Healthcare Acquisition Partners Corp. is a blank check company recently formed for the purpose of acquiring, through a merger, capital stock exchange, asset acquisition or other similar business combination, one or more operating businesses in the healthcare sector. This is an initial public offering of our securities. Each unit that we are offering consists of:

Each warrant entitles the holder to purchase one share of our common stock at a price of $5.00. Each warrant will become exercisable on the later of our completion of a business combination and 12 months from the date on which this offering is completed, and will expire on , or earlier upon redemption.

We have granted the underwriters a 45-day option to purchase up to 2,500,000 additional units solely to cover over-allotments, if any (over and above the 16,666,667 units referred to above). We have also agreed to sell to FTN Midwest Securities Corp., the representative of the underwriters, for $100, as additional compensation, an option to purchase up to a total of 958,333 units at a price of $7.50 per unit. The units issuable upon exercise of this option are identical to those offered by this prospectus, except that each of the warrants underlying such units entitles the holder to purchase one share of our common stock at a price of $6.25. The purchase option and its underlying securities have been registered under the registration statement of which this prospectus forms a part.

There is presently no public market for our units, common stock or warrants. We anticipate that the units will be quoted on the OTC Bulletin Board promptly after the date of this prospectus. Each of the common stock and warrants will begin separate trading 20 days after the earlier of the expiration of the underwriters’ over-allotment option or the exercise in full by the underwriters of such option. Once the common stock and warrants comprising the units begin separate trading, we anticipate that the common stock and warrants will be traded on the OTC Bulletin Board.

Investing in our securities involves a high degree of risk. See “ Risk Factors” beginning on page 8 of this prospectus for a discussion of information that should be considered in connection with an investment in our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Of the net proceeds we receive from this offering, $89,595,000 ($5.38 per unit) will be deposited into a trust account at JPMorgan Chase Bank, N.A.

FTN Midwest Securities Corp. holds all of the membership interests in our initial shareholder and is also the lead manager and sole book runner in this offering. FTN Midwest Securities Corp. or any of its affiliates may use this prospectus in connection with offers and sales of the securities in market-making transactions after their initial sale.

We are offering the units for sale on a firm-commitment basis. FTN Midwest Securities Corp., acting as representative of the underwriters, expects to deliver our securities to investors in the offering on or about , 2005.

You should rely only on the information contained or incorporated by reference in this prospectus. We have not, and the underwriters have not, authorized anyone to provide you with different information. We are not making an offer of these securities in any jurisdiction where the offer is not permitted. You should not assume that the information in this prospectus is accurate as of any date other than the date on the front cover of this prospectus.

This prospectus contains forward-looking statements that involve substantial risks and uncertainties as they are not based on historical facts, but rather are based on current expectations, estimates and projections about our industry, our beliefs, and our assumptions. These statements are not guarantees of future performance and are subject to risks, uncertainties, and other factors, some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. You should not place undue reliance on any forward-looking statements, which apply only as of the date of this prospectus.

This summary highlights certain information appearing elsewhere in this prospectus. For a more complete understanding of this offering, you should read the entire prospectus carefully, including the risk factors and the financial statements, and the notes and schedules related thereto. Unless otherwise stated in this prospectus, references to “we,” “us” or “our” refer to Healthcare Acquisition Partners Corp. Unless we tell you otherwise, the information in this prospectus assumes that the underwriters have not exercised their over-allotment option and that FTN Midwest Securities Corp. has not exercised its purchase option.

Unless we tell you otherwise, the term “business combination” as used in this prospectus means an acquisition of, through a merger, capital stock exchange, asset acquisition or other similar business combination, one or more operating businesses. In addition, unless we tell you otherwise, the term “initial stockholder” as used in this prospectus refers to Healthcare Acquisition Partners Holdings, LLC, which hold all of the shares of our common stock prior to the date of this prospectus. Further, unless we tell you otherwise, the term “public stockholders” as used in this prospectus refers to those persons that purchase the securities offered by this prospectus, including members of our initial stockholder if they purchase these securities either in this offering or afterwards, provided that the term “public stockholders” shall only apply to such holders to the extent of those securities so purchased in this offering or afterwards. Our initial stockholder will agree not to purchase any additional shares of common stock, whether as part of this offering or otherwise, prior to the completion of a business combination. Unless the context indicates otherwise, numbers in this prospectus have been rounded and are, therefore, approximate.

We are a blank check company incorporated under the laws of Delaware on August 15, 2005. We were formed for the purpose of acquiring, through a merger, capital stock exchange, asset acquisition or other similar business combination, one or more operating businesses in the healthcare sector. By healthcare sector, we mean a company engaged in the business of providing goods and services in the healthcare industry, such as a healthcare service provider, drug manufacturer or healthcare device company. To date, our efforts have been limited to organizational activities and activities relating to this offering. We do not have any specific business combination under consideration, and neither we, nor any representative acting on our behalf, has had any contacts with any target businesses regarding a business combination, nor taken any direct or indirect actions to locate or search for a target business regarding a business combination.

Through the members of our management team and our directors, we have extensive contacts and sources from which to generate acquisition opportunities in the healthcare sector. These contacts and sources include private equity and venture capital funds, public and private companies, investment bankers, attorneys and accountants. The members of our management team intend to maintain relationships with a significant number of private equity and venture capital funds.

$4.8 billion in venture investment into U.S. healthcare companies in the first nine months of 2004 alone. Within this industry we believe there are numerous niche sectors each with potential markets totaling in the hundreds of millions of dollars. While some of these sectors are serviced by large traditional healthcare institutions, we believe many are nascent with significant opportunities for fast-moving, smaller companies.

While we may seek to effect business combinations with more than one target business, our initial business acquisition must be with one or more operating businesses whose fair market value is, either individually or collectively, at least equal to 80% of our net assets at the time of such acquisition.

We are a Delaware corporation that was formed on August 15, 2005. Our executive offices are located at 350 Madison Avenue, New York, New York 10017, and our telephone number is (212) 418-5050.

Our initial stockholder is Healthcare Acquisition Partners Holdings, LLC, a limited liability company organized in Delaware. Healthcare Acquisition Parent, LLC, a limited liability company organized in Delaware currently holds 100% of the membership interests in our initial stockholder. John Voris, our chief executive officer and a member of our board, Erin Enright, our chief financial officer, and Wayne Yetter and Jean-Pierre Millon, members of our board, will be granted, prior to completion of this offering, membership interests in our initial stockholder representing 14%, 4%, 8% and 8% respectively. Healthcare Acquisition Parent, LLC is the managing member of our initial stockholder, and as such, has authority to make decisions on behalf of all members of our initial stockholder. The membership interests of Healthcare Acquisition Parent, LLC are held by FTN Midwest Securities Corp. William Bischoff, a managing director at FTN Midwest Securities Corp., is the manager of Healthcare Acquisition Parent, LLC. The common stock held by the initial stockholder will be subject to a lock-up agreement restricting its sale until six months after a business combination is completed. The membership interests in Healthcare Acquisition Partners Holdings, LLC and Healthcare Acquisition Parent, LLC will be subject to similar lock-up agreements. The members of each of Healthcare Acquisition Partners Holdings, LLC and Healthcare Acquisition Parent, LLC will agree not to dissolve those entities prior to the earlier of the date that is six months after the completion of a business combination and the date of our liquidation.

The remaining 66% of the membership interests in our initial stockholder held by Healthcare Acquisition Parent, LLC may be allocated to current or future members of our management and/or to employees of FTN Midwest Securities Corp. and its affiliates. These interests may be subject to vesting requirements.

We believe that the offering size of approximately $100,000,000 is sufficient to enable us to acquire an operating company that is of a suitable size to be a publicly traded reporting company. Our management has prepared a budget for our anticipated costs, essentially related to the identification of an acquisition target and the negotiation, preparation and consummation of an acquisition, with a view to putting as much of the offering proceeds as possible, after underwriting commissions and expenses related to this offering, in trust. All offering proceeds in excess of what we anticipate needing to identify an acquisition target and complete a business combination will be put in trust for the benefit of the purchasers of units in this offering. As set forth under “Use of Proceeds,” we are committed to putting $89,596,000 into a trust account (assuming no exercise of the underwriters’ over-allotment option). We believe that the initial unit price of $6.00 is appropriate to attract investors while meeting our projected needs and we note that other blank check companies have used similar price-ranges.

Proceeds from the exercise, if any, of the warrants will be paid directly to us. Those proceeds will not be held in trust and may be used as the board of directors approves or directs. For more information, see the section entitled “Description of Securities— Warrants” in this prospectus.

The following table summarizes the relevant financial data for our business and should be read in conjunction with our financial statements, and the notes and schedules related thereto, which are included in this prospectus. We have not had any significant operations to date, so only balance sheet data is presented.

The “as adjusted” information gives effect to the sale of the units in this offering and the application of the estimated net proceeds.

The working capital (as adjusted) and total assets (as adjusted) amounts include $89,595,000 being held in the trust account, which will be available to us only upon the consummation of a business combination within the time period described in this prospectus. If a business combination is not so consummated, we will be liquidated and the proceeds held in the trust account will be distributed solely to our public stockholders.

We will not proceed with a business combination that has been approved by a majority of shares of common stock voted by our stockholders if public stockholders owning 20% or more of the shares sold in this offering both vote against the business combination and exercise their conversion rights. Accordingly, we may effect a business combination only if public stockholders owning less than 20% of the shares sold in this offering exercise their conversion rights. If this occurred, we would be required to convert to cash up to approximately 19.99% of the 16,666,667 shares of common stock sold in this offering, or 3,331,667 shares of common stock, at an initial per share conversion price of $5.38 plus interest earned thereon in the trust account. The actual per share conversion price will be equal to the amount in the trust account, including all accrued interest, at the close of business on the second business day prior to the proposed consummation of the business combination, divided by the number of shares of common stock sold in this offering.

An investment in our securities involves a high degree of risk. You should consider carefully all of the risks described below, together with the other information contained in this prospectus, before making a decision to invest in our securities. If any of the following events occur, our business, financial conditions and results of operations may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment.

We are a development stage company with no operating history and, accordingly, you will have no basis upon which to evaluate our ability to achieve our business objective.

We are a recently incorporated development stage company with no operating results to date. Therefore, our ability to begin operations is dependent upon obtaining financing through the public offering of our securities. Since we do not have an operating history, you will have no basis upon which to evaluate our ability to achieve our business objective, which is to acquire one or more operating businesses in the healthcare-related sector. We have not conducted any discussions and we have no plans, arrangements or understandings with any prospective acquisition candidates. We will not generate any revenues until, at the earliest, after the consummation of a business combination. We cannot assure you as to when or if a business combination will occur.

We may not be able to consummate a business combination within the required time frame, in which case, we would be forced to liquidate.

We must complete a business combination with a fair market value of at least 80% of our net assets at the time of acquisition within 18 months after the consummation of this offering (or within 24 months after the consummation of this offering if a definitive agreement relating to a business combination has been executed within 18 months after the consummation of this offering). If we fail to consummate a business combination in the healthcare sector within the required time frame, we will be forced to liquidate our assets. We may not be able to find suitable target businesses within the required time frame. In addition, our negotiating position and our ability to conduct adequate due diligence on any potential target may be reduced as we approach the deadline for the consummation of a business combination. We do not have any specific business combination under consideration, and neither we, nor any representative acting on our behalf, has had any contacts with any target businesses regarding a business combination, nor taken any direct or indirect actions to locate or search for a target business regarding a business combination.

If we are forced to liquidate before a business combination, our public stockholders will receive less than $6.00 per share upon distribution of the trust account and our warrants will expire worthless.

If we are unable to complete a business combination and are forced to liquidate our assets, the per-share liquidation distribution on the shares of common stock sold in this offering will be less than $6.00 because of the expenses related to this offering, our general and administrative expenses and the anticipated costs of seeking a business combination. Furthermore, the warrants will expire worthless if we liquidate before the completion of a business combination.

You will not be entitled to protections normally afforded to investors of blank check companies under federal securities laws.

Since the net proceeds of this offering are intended to be used to complete a business combination with one or more operating businesses in the healthcare sector that have not been identified, we may be deemed to be a “blank check” company under the federal securities laws. However, since we will have net tangible assets in

excess of $5,000,000 upon the successful consummation of this offering and will file a Current Report on Form 8-K with the SEC upon consummation of this offering including an audited balance sheet demonstrating this fact, we believe that we are exempt from rules promulgated by the SEC to protect investors in blank check companies such as Rule 419. Accordingly, investors will not be afforded the benefits or protections of those rules. Because we do not believe we are subject to Rule 419, our units will be immediately tradeable and we will have a longer period of time within which to complete a business combination in certain circumstances. For a more detailed comparison of this offering to offerings under Rule 419, see the section below entitled “Proposed Business—Comparison to offerings of blank check companies.”

If third parties bring claims against us, the proceeds held in trust could be reduced and the per-share liquidation distribution received by stockholders could be less than $5.38 per share.

Our placing of funds in trust may not protect those funds from third party claims against us. Although we will seek to have all vendors, prospective target businesses or other entities we engage waive any right, title, interest or claim of any kind in or to any monies held in the trust account for the benefit of our public stockholders, there is no guarantee that they will execute such waivers. Nor is there any guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the trust account for any reason. Neither our initial stockholder, nor any of our directors or officers will agree to be personally liable for, or to indemnify us against, these liabilities. Accordingly, the proceeds held in trust could be subject to claims which could take priority over the claims of our public stockholders and the per-share liquidation price could be less than $5.38, plus interest, due to claims of such creditors.

Since we have not currently selected any prospective target businesses with which to complete a business combination, investors in this offering are unable to currently ascertain the merits or risks of any particular target business’ operations.

Since we have not yet selected or approached any prospective target businesses, investors in this offering have no current basis to evaluate the possible merits or risks of any particular target business’ operations. While it is unlikely that we would complete a business combination with a financially unstable company or an entity in its development stage, if we determined that one or more of such entities met our criteria, it is possible that our board of directors would recommend, and our stockholders would approve, a business combination with one or more of such entities. Although our management will endeavor to evaluate the risks inherent in a particular target business, we cannot assure you that we will properly ascertain or assess all of the significant risk factors, or that we will have adequate time to complete due diligence. We also cannot assure you that an investment in our units will not ultimately prove to be less favorable to investors in this offering than a direct investment, if an opportunity were available, in any particular target business. For a more complete discussion of our selection of target businesses, see the section below entitled “Proposed Business—Effecting a business combination—We have not selected or approached any target businesses.”

We may issue shares of our capital stock, including through convertible debt securities, to complete a business combination, which would reduce the equity interest of our stockholders and likely cause a change in control of our ownership.

Our Amended and Restated Certificate of Incorporation authorizes the issuance of up to 200,000,000 shares of common stock, par value $.0001 per share, and 1,000,000 shares of preferred stock, par value $.0001 per share. Immediately after this offering (assuming no exercise of the underwriters’ over-allotment option), there will be 142,958,333 authorized but unissued shares of our common stock available for issuance (after appropriate reservation for the issuance of shares upon full exercise of our outstanding warrants and the purchase option granted to FTN Midwest Securities Corp.) and all of the 1,000,000 shares of preferred stock available for issuance. Although we have no commitments as of the date of this offering to issue any securities, we may issue a substantial number of additional shares of our common stock or preferred stock, or a combination of both,

including through convertible debt securities, to complete a business combination. The issuance of additional shares of our common stock or any number of shares of preferred stock, including upon conversion of any debt securities:

For a more complete discussion of the possible structure of a business combination, see the section below entitled “Proposed Business—Effecting a business combination—Selection of target businesses and structuring of a business combination.”

We may issue notes or other debt securities, assume debt of a target business, or otherwise incur substantial debt, to complete a business combination, which may adversely affect our leverage and financial condition.

We may choose to issue a substantial amount of notes or other debt securities, assume outstanding indebtedness of a target business, or opt to incur substantial debt, or a combination of the aforementioned, to complete a business combination. The issuance of notes or other debt securities, the assumption of a target business’s indebtedness, or the incurrence of debt:

Our ability to be successful after a business combination will be largely dependent upon the efforts of the key personnel who will join us following a business combination, who may be unfamiliar with the requirements of operating a public company.

Our ability to successfully effect a business combination will be dependent upon the efforts of our key personnel. The future role of our management personnel following a business combination, however, cannot presently be fully ascertained. Specifically, our current officers have no obligation to remain with us subsequent to a business combination (nor have any indicated an intent to leave). Depending on the target company’s management composition, we therefore may have to employ other personnel following the business combination. While we intend to closely scrutinize any additional individuals we engage after a business combination, we cannot assure you that our assessment of these individuals will prove to be correct. These individuals may be unfamiliar with the requirements of operating a public company as well as with United States securities laws which could cause us to have to expend time and resources helping them become familiar with such laws. This could be expensive and time-consuming and could lead to various regulatory problems that may adversely affect our operations.

Our officers and directors will allocate their time to other businesses, which could produce conflicts of interest in their determination as to how much time to devote to our affairs and could cause us to be less efficient in completing an acquisition than a competitor.

We do not intend to have any full time employees prior to the consummation of a business combination. Each of our officers and directors is engaged in other business endeavors and is not required to, and will not, commit their full time to our affairs, which may result in a conflict of interest in allocating their time between our operations and other businesses. This could cause us to be less efficient in completing an acquisition than a prospective competitor or otherwise have a negative impact on our ability to consummate a business combination. If our officers’ and directors’ other business affairs require them to devote substantial amounts of time to such affairs in excess of their current commitment levels, it could limit their ability to devote time to our affairs and could have a negative impact on our ability to consummate a business combination. We cannot assure you that these conflicts will be resolved in our favor.

Sean McDevitt, the chairman of our board, and Pat LaVecchia, our vice-president and secretary and a director, are each managing directors of FTN Midwest Securities Corp., the representative of the underwriters in this offering and the beneficial owner of a controlling interest in our initial stockholder. We cannot assure you that their interest as principals of our underwriter will not conflict with your interest as investors.

For a complete discussion of the potential conflicts of interest that you should be aware of, see the section below entitled “Certain Relationships and Related Transactions.”

Certain of our officers and directors are currently, and all may in the future become, affiliated with entities engaged in business activities similar to those intended to be conducted by us and, accordingly, may have conflicts of interest in determining to which entity, and in what priority, a particular business opportunity should be presented.

John Voris, our CEO and a director, Erin Enright, our CFO, Jean-Pierre Milton, one of our directors, and Wayne Yetter, one of our directors, are currently, and all of our officers and directors may in the future become, affiliated with entities engaged in business activities similar to those intended to be conducted by us. See the section below entitled “Management—Directors and Executive Officers.” In addition, all of our officers and directors may in the future become affiliated with other “blank check” companies. Our officers and directors may become aware of business opportunities which may be appropriate for presentation to us as well as the other entities with which they are or may be affiliated. Due to these existing affiliations, they may have fiduciary obligations to present potential business opportunities to those entities prior to presenting them to us which could cause additional conflicts of interest. Accordingly, they may have conflicts of interest in determining to which entity, and in what priority, a particular business opportunity should be presented. We have entered into agreements with FTN Midwest Securities Corp. and certain of our officers and directors, under the terms of which each of them has agreed to present to us for our consideration any opportunity to acquire all or substantially all of the outstanding equity securities of, or otherwise acquire a controlling equity interest in, an operating business in the healthcare, or a healthcare-related, sector, provided that they are under no obligation to present to us any opportunity involving a business in the healthcare, or a healthcare-related, sector seeking a strategic combination with another operating business in the healthcare, or a healthcare-related, sector. The terms of these agreements do not obligate these individuals or FTN Midwest Securities Corp. to present any opportunities to us for consideration prior to presenting such opportunities to any other person or entity. We cannot assure you that any conflicts that do arise will be resolved in our favor. For a complete discussion of our management’s business affiliations and the potential conflicts of interest that you should be aware of, see the sections below entitled “Management—Directors and Executive Officers” and “Certain Relationships and Related Transactions.”

Because our directors and officers may indirectly own shares of our common stock through our initial stockholder that will not participate in any liquidation distributions of the trust funds, they may have a conflict of interest in determining whether a particular target business is appropriate for a business combination.

Our directors and officers, other than Sean McDevitt and Pat LaVecchia, will become members of our initial stockholder and will, as a result, indirectly own shares of our common stock that were issued prior to this offering. Our initial stockholder will not have the right to receive distributions from the trust account upon our liquidation in the event we fail to complete a business combination within the time frame provided in this prospectus. Those shares and warrants that will be indirectly owned by our management will be worthless if we do not consummate a business combination. The personal and financial interests of our management may influence their motivation in identifying and selecting target businesses and completing a business combination in a timely manner. Consequently, our directors’ and officers’ discretion in identifying and selecting suitable target businesses may result in a conflict of interest when determining whether the terms, conditions and timing of a particular business combination are appropriate and in our public stockholders’ best interest.

Our underwriter owns a controlling interest in our initial stockholder and as a result exercises control over us.

Prior to completion of this offering, FTN Midwest Securities Corp., the representative of the underwriters in this offering, will continue to be the beneficial owner of a controlling interest in our initial stockholder. As a result, FTN has made certain decisions concerning our structure, operations and management, and, subject to the requirement that our independent directors make certain decisions, is expected to continue to play a significant role. After this offering has been consummated, FTN, through its majority holding in our initial stockholder, will continue to exercise considerable indirect influence over our operations. We cannot assure you that its interest as underwriter will not conflict with your interest as investors. For a complete discussion of the potential conflicts of interest that you should be aware of, see the sections below entitled “Management—Conflicts of Interest” and “Certain Relationships and Related Transactions.”

If our common stock becomes subject to the SEC’s penny stock rules, broker-dealers may experience difficulty in completing customer transactions and trading activity in our securities may be adversely affected.

If at any time we have net tangible assets of $5,000,000 or less and our common stock has a market price per share of less than $5.00, transactions in our common stock may be subject to the “penny stock” rules promulgated under the Securities Exchange Act of 1934, as amended. Under these rules, broker-dealers who recommend such securities to persons other than institutional accredited investors must:

If our common stock becomes subject to these rules, broker-dealers may find it difficult to effect customer transactions and trading activity in our securities may be adversely affected. As a result, the market price of our securities may become depressed, and you may find it difficult to sell our securities.

We may only be able to complete one initial business combination, which may cause us to be solely dependent on a single business and a limited number of products or services permanently or for an extended period.

This offering will provide us with net proceeds of approximately $91,475,000, which we may use to complete a business combination. While we intend subsequently to effect a business combination with more than one target business, our initial business acquisition must be with one or more operating businesses whose fair market value, collectively, is at least equal to 80% of our net assets at the time of such acquisition. We may not be able to acquire more than one target business because of various factors, including insufficient financing or the difficulties inherent in consummating the contemporaneous acquisition of more than one operating business. Therefore, it is possible that we will only be able to complete an initial business combination with a single operating business, which may have only a limited number of products or services. The resulting lack of diversification may:

In this case, we will not be able to diversify our operations or benefit from the possible spreading of risks or offsetting of losses, unlike other entities which may have the resources to complete several business combinations in different industries or different areas of a single industry so as to diversify risks and offset losses. Further, the prospects for our success may be entirely dependent upon the future performance of the initial target business or businesses we acquire.

In addition, since our business combination may entail the contemporaneous acquisition of several operating businesses and may be with different sellers, we will need to convince such sellers to agree that the purchase of their businesses is contingent upon the simultaneous closings of the other acquisitions.

Because of our limited resources and the significant competition for business combination opportunities, we may not be able to consummate an attractive business combination.

We expect to encounter intense competition from other entities having a business objective similar to ours, including venture capital funds, leveraged buyout funds and operating businesses competing for acquisitions. Many of these entities are well established and have extensive experience in identifying and effecting business combinations directly or through affiliates. Many of these competitors possess greater technical, human and other resources than we do and our financial resources will be relatively limited when contrasted with those of many of these competitors. While we believe that there are numerous potential target businesses in the healthcare sector that we could acquire with the net proceeds of this offering, our ability to compete in acquiring certain sizable target businesses will be limited by our available financial resources. This inherent competitive limitation gives others an advantage over us in pursuing the acquisition of certain target businesses. Further:

Any of these obligations may place us at a competitive disadvantage in successfully negotiating and completing a business combination.

In addition, because our business combination may entail the contemporaneous acquisition of several operating businesses and may be with several different sellers, we will need to convince such sellers to agree that the purchase of their businesses is contingent upon the simultaneous closings of the other acquisitions.

We may be unable to obtain additional financing, if required, to complete a business combination or to fund the operations and growth of the target business, which could compel us to restructure or abandon a particular business combination.

Although we believe that the net proceeds of this offering will be sufficient to allow us to consummate a business combination, since we have not yet selected or approached any prospective target businesses, we cannot ascertain the capital requirements for any particular business combination. If the net proceeds of this offering prove to be insufficient, either because of the size of the business combination or the depletion of the available net proceeds in search of target businesses, or because we become obligated to convert into cash a significant number of shares from dissenting stockholders, we will be required to seek additional financing through the issuance of equity or debt securities or other financing arrangements. We cannot assure you that such financing would be available on acceptable terms, if at all. To the extent that additional financing proves to be unavailable when needed to consummate a particular business combination, we would be compelled to restructure or abandon that particular business combination and seek alternative target business candidates. In addition, if we consummate a business combination, we may require additional financing to fund the operations or growth of the target businesses. The failure to secure additional financing could have a material adverse effect on the continued development or growth of the target businesses. None of our officers, directors or initial stockholder is required to provide any financing to us in connection with or after a business combination.

Our initial stockholder controls a substantial interest in us and thus may influence certain actions requiring stockholder vote and could support proposals that are not in your interest.

Upon consummation of this offering, our initial stockholder will own approximately 20% of our issued and outstanding shares of common stock. Healthcare Acquisition Parent, LLC is the managing member of our initial stockholder, and certain of our other officers and directors will be members. William Bischoff, a managing director of FTN Midwest Securities Corp., is the managing member of Healthcare Acquisition Parent, LLC. Prior to the completion of this offering, our initial stockholder, each member of our initial stockholder, and each member of Healthcare Acquisition Parent, LLC will enter into lock-up agreements restricting the sale of shares of our common stock, interests in our initial stockholder and interests in Healthcare Acquisition Parent, LLC until six months after a business combination is completed. In addition, each member of our initial stockholder and of Healthcare Acquisition Parent, LLC will agree not to dissolve those entities prior to the earlier of the date that is six months after the completion of a business combination and the date of our liquidation.

In connection with the vote required for our initial business combination, our initial stockholder has agreed to vote all of the shares of common stock owned by it immediately before this offering in the same way as the holders of the majority of the shares sold to the public in this offering and any other public offering.

It is unlikely that there will be an annual meeting of stockholders to elect new directors prior to the consummation of a business combination, in which case all of the current directors will continue in office at least until the consummation of the business combination. If there is an annual meeting, our initial stockholder, because of its ownership position, will have considerable influence regarding the outcome of the election. Accordingly, our initial stockholder will continue to exert considerable control at least until the consummation of a business combination. Our initial stockholder will agree not to purchase any additional shares of common stock, whether as part of this offering or otherwise, prior to the completion of a business combination, but its members and their affiliates are not prohibited from purchasing units in this offering or shares offered hereby in the aftermarket, and they will have full voting rights with respect to any shares of common stock they may acquire, either through this offering or in subsequent market transactions. If they do, we cannot assure you that our initial stockholder’s members and their affiliates will not have considerable influence upon the vote in connection with a business combination.

Our initial stockholder paid approximately $0.006 per share for its shares and, accordingly, you will experience immediate and substantial dilution from the purchase of our common stock.

The difference between the public offering price per share of our common stock and the pro forma net tangible book value per share of our common stock after this offering constitutes the dilution to you and the other investors in this offering. The fact that our initial stockholder acquired its shares of common stock prior to this offering at a nominal price has significantly contributed to this dilution. Assuming this offering is completed, you and the other new investors will incur an immediate and substantial dilution of approximately 30% or $1.80 per share (the difference between the pro forma net tangible book value per share of $4.20 and the public initial offering price of $6.00 per unit).

Our outstanding warrants may have an adverse effect on the market price of our common stock and make it more difficult to effect a business combination.

In connection with this offering, as part of the units, we will be issuing warrants to purchase 38,333,334 shares of common stock (assuming full exercise of the underwriters’ over-allotment option). In addition, we have agreed to sell to FTN Midwest Securities Corp. an option to purchase up to a total of 958,333 units that, if exercised, would result in the issuance of warrants to purchase an additional 1,916,666 shares of common stock. To the extent we issue shares of common stock to effect a business combination, the potential for the issuance of substantial numbers of additional shares upon exercise of these warrants could make us a less attractive acquisition vehicle in the eyes of a target business as such warrants, when exercised, will increase the number of issued and outstanding shares of our common stock and reduce the value of the shares issued to complete the business combination. Accordingly, our warrants may make it more difficult to effectuate a business combination or increase the cost of a target business. Additionally, the sale, or even the possibility of sale, of the shares underlying the warrants could have an adverse effect on the market price for our securities or on our ability to obtain future public financing. If and to the extent these warrants are exercised, you may experience dilution to your holdings.

If our initial stockholder exercises its registration rights, it may have an adverse effect on the market price of our common stock and the existence of these rights may make it more difficult to effect a business combination.

Our initial stockholder is entitled to demand that we register the resale of its shares of common stock in certain circumstances. For more information, see “Certain Relationships and Related Transactions—Initial Share Issuances” in this prospectus. If our initial stockholder exercises its registration rights with respect to all of its shares of common stock, then there will be an additional 4,166,667 shares of common stock eligible for trading in the public market. The presence of this additional number of shares of common stock eligible for trading in the public market may have an adverse effect on the market price of our common stock. In addition, the existence of these rights may make it more difficult to effect a business combination or increase the cost of a target business, as the stockholders of a particular target business may be discouraged from entering into a business combination with us or will request a higher price for their securities as a result of these registration rights and the potential future effect their exercise may have on the trading market for our common stock.

The securities being offered will be available for sale to individuals in only a limited number of states and you may only be able to purchase the securities if you are an institutional investor as defined under applicable state securities laws. In addition, there may be restrictions under applicable state securities laws on an investor’s ability to resell the securities it purchases in the offering.

We will seek to register or otherwise qualify the securities for offer and sale to individuals in only a limited number of states and jurisdictions. If you reside in a state or jurisdiction where the securities will not be registered or qualified for sale, you will only be able to purchase securities in the offering if you are an institutional investor as defined under the securities laws of your state. The definition of an “institutional investor” varies from state to state but generally includes banks and other financial institutions, broker-dealers,

insurance companies, pension or profit-sharing plans, and other qualified entities. You should consult with your own financial and legal advisors to determine whether you would qualify as an institutional investor under the laws of your state.

Even if you are able to purchase securities in this offering, your ability to resell your securities will also be limited by applicable state securities laws. You may be able to resell your securities only in the states in which the securities are registered or only to persons who qualify as institutional investors., which may have an adverse impact upon the price of the securities. For more information, see “Underwriting—State Blue Sky Information” in this prospectus.

We intend to have our securities quoted on the OTC Bulletin Board, which will limit the liquidity and price of our securities more than if our securities were quoted or listed on the Nasdaq National Market or a national exchange.

Our securities will be traded in the over-the-counter market. It is anticipated that they will be quoted on the OTC Bulletin Board, an inter-dealer automated quotation system for equity securities sponsored and operated by The Nasdaq Stock Market, Inc., but not included in the Nasdaq National Market. Quotation of our securities on the OTC Bulletin Board will limit the liquidity and price of our securities more than if our securities were quoted or listed on the Nasdaq National Market or a national exchange. Lack of liquidity will limit the price at which you may be able to sell our securities or your ability to sell our securities at all.

None of our initial stockholder, our directors and officers, or any other person has committed to us to purchase warrants in the market. This may impact the liquidity and price of the warrants once they begin to trade separately from our common stock.

If we are deemed to be an investment company, we may be required to institute burdensome compliance requirements and our activities may be restricted, which may make it difficult for us to complete a business combination.

If we are deemed to be an investment company under the Investment Company Act of 1940, as amended, our activities may be restricted, including:

We do not believe that our anticipated principal activities will subject us to the Investment Company Act of 1940, as amended. To this end, the proceeds held in trust may only be invested by the trust agent in a money market fund, selected by us, which invests principally in short-term securities issued or guaranteed by the United States having a rating in the highest investment category granted thereby by a recognized credit rating agency at the time of acquisition with specific maturity dates. By restricting the investment of the proceeds to these instruments, we intend to meet the requirements for the exemption provided in Rule 3a-1 under the Investment Company Act of 1940. If we were deemed to be subject to the act, compliance with these additional regulatory burdens would require additional expense that we have not allotted for.

Because there are numerous companies with a business plan similar to ours seeking to complete a business combination, it may be more difficult for us to complete a business combination.

Published reports indicate that between 33 to 42 similarly structured blank check companies filed initial public offerings with the Securities and Exchange Commission from January 2005 through October 2005. Of

these companies, few have announced that they have entered into a definitive agreement for a business combination, while even fewer have consummated a business combination. According to the Investment Dealers Digest, through October 2005, 19 such initial public offerings have been completed so far this year, raising a total of $1.1 billion, while nine IPOs raised $339.6 million in 2004. While some of those companies have targeted specific industries in which they must complete a business combination and only a few have targeted the healthcare industry, a number of them may consummate a business combination in any industry they choose. Competition from these and other companies seeking to consummate a business plan similar to ours could increase demand for attractive target companies. Further, the fact that very few of such companies have entered into a definitive agreement for a business combination and even fewer have completed a business combination may be an indication that there are only a limited number of attractive target businesses available or that target businesses may not be inclined to enter into business combinations with publicly held blank check companies like us. Therefore, we cannot assure you that we will be able to successfully compete for an attractive business combination, nor can we assure you that we will be able to effectuate a business combination within the required time period. If we are unable to find a suitable target business within such time periods, we will be forced to liquidate and the portion of your investment not placed in trust would be lost.

The healthcare industry is susceptible to significant liability exposure. If liability claims are brought against us following a business combination, the defense of such claims could consume management’s time and our resources and a negative outcome could disrupt our operations.

Any target business we acquire in the healthcare industry will be exposed to potential liability risks that are inherent in the testing, manufacturing, marketing and sale of healthcare products and/or the provision of healthcare services. A successful liability claim could have material adverse effect on our business, financial condition or market price of our common stock and warrants. In addition, the time, energy and attention that our management could be required to devote to confronting any such claims could prevent it from concentrating on the growth and profitability of our acquired business, which could have a material impact on our financial results and the market prices of our securities.

Changes in the healthcare industry are subject to various influences, each of which may affect our prospective business.

The healthcare industry is subject to changing political, economic, and regulatory influences. These factors affect the purchasing practices and operations of healthcare organizations. Any changes in current healthcare financing and reimbursement systems could cause us to make unplanned enhancements of our prospective products or services, or result in delays or cancellations of orders, or in the revocation of endorsement of our prospective products or services by clients. Federal and state legislatures have periodically considered programs to reform or amend the U.S. healthcare system at both the federal and state level. Such programs may increase governmental regulation or involvement in healthcare, lower reimbursement rates, or otherwise change the environment in which healthcare industry participants operate. Healthcare industry participants may respond by reducing their investments or postponing investment decisions, including investments in our prospective products or services.

Many healthcare industry participants are consolidating to create integrated healthcare systems with greater market power. As the healthcare industry consolidates, competition to provide products and services to industry participants will become even more intense, as will the importance of establishing a relationship with each industry participant. These industry participants may try to use their market power to negotiate price reductions for our prospective products and services. If we were forced to reduce our prices, our operating results could suffer if we could not achieve corresponding reductions in our expenses.

Any business we acquire will be subject to extensive government regulation. Any business changes to the laws and regulations governing our prospective business, or the interpretation and enforcement of those laws or regulations, could cause us to modify our operations and could result in increased costs.

We believe that our prospective business will be extensively regulated by the federal government and any states in which we decide to operate. The laws and regulations governing our operations, if any, are generally intended to benefit and protect persons other than our stockholders. The government agencies administering these laws and regulations have broad latitude to enforce them. These laws and regulations along with the terms of any government contracts we may enter into would regulate how we do business, what products and services we could offer, and how we would interact with the public. These laws and regulations, and their interpretations, are subject to frequent change. Changes in existing laws or regulations, or their interpretations, or the enactment of new laws or regulations could reduce our revenue, if any, by:

For example, Congress enacted the Health Insurance Portability and Accountability Act of 1996 which had serious implications for the healthcare industry, including the imposition of a vast array of additional requirements with respect to privacy protections, electronic security protections, and additional requirements with respect to the manner in which health care transactions (such as claim submissions) must be conducted. Another example of recently enacted and far-reaching legislation is the Medicare Prescription Drug, Improvement and Modernization Act of 2003, which will have very significant effects in greatly increasing the level of federal expenditures for prescription drugs. The new legislation will alter the nature and degree of reimbursement for drugs and for healthcare services as it is phased in in 2006. Any analogous requirements applied to our prospective products or services would be costly to implement and could affect our prospective revenues.

We believe that our business, if any, will be subject to various routine and non-routine governmental reviews, audits and investigation. Violation of the laws governing our prospective operations, or changes in interpretations of those laws, could result in the imposition of civil or criminal penalties, the cancellation of any contracts to provide products or services, the suspension or revocation of any licenses, and exclusion from participation in government sponsored health programs, such as Medicare, Medicaid and the State Children’s Health Insurance Program. If we become subject to material fines or if other sanctions or other corrective actions were imposed upon us, we might suffer a substantial reduction in revenue, and might also lose one or more of our government contracts and as a result lose significant numbers of members and amounts of revenue.

For example, in recent years there have been an increasing number of investigations for sales under federal and state anti-kickback statutes relating to Medicare and Medicaid reimbursement and the federal False Claims Act and its state analogues, with settlements often reaching into the several hundred million dollar range. This risk applies to both healthcare service providers and medical device manufacturers. Investigations in this area will be further stimulated by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003.

The current administration’s issuance of new regulations, its enforcement of the existing laws and regulations, the states’ ability to promulgate stricter rules, and uncertainty regarding many aspects of the regulations may make compliance with any new regulatory landscape difficult. In order to comply with any new regulatory requirements, any prospective business we acquire may be required to employ additional or different programs and systems, the costs of which are unknown to us at this time. Further, compliance with any such new

regulations may lead to additional costs that we have not yet identified. We do not know whether, or the extent to which, we would be able to recover our costs of complying with any new regulations. Any new regulations and the related compliance costs could have a material adverse effect on our business.

If we are unable to attract qualified healthcare professionals at reasonable cost, it could limit our ability to grow and could decrease our profitability.

We may rely significantly on our ability to attract and retain qualified healthcare professionals who possess the skills, experience and licenses necessary to meet the certification requirements and the requirements of the hospitals, nursing homes and other healthcare facilities with which we may work, as well as the requirements of applicable state and federal governing bodies. We will compete for qualified healthcare professionals with hospitals, nursing homes and other healthcare organizations. Currently, for example, there is a shortage of qualified nurses in most areas of the United States. Therefore, competition for nursing personnel is increasing, and nurses’ salaries and benefits have risen. This may also occur with respect to other healthcare professionals on whom our business may become dependent.

Our ability to attract and retain such qualified healthcare professionals will depend on several factors, including our ability to provide attractive assignments and competitive benefits and wages. We cannot assure you that we will be successful in any of these areas. Because we may operate in a fixed reimbursement environment, increases in the wages and benefits that we must provide to attract and retain qualified healthcare professionals or increases in our reliance on contract or temporary healthcare professionals could negatively affect our revenue. We may be unable to continue to increase the number of qualified healthcare professionals that we recruit, decreasing the potential for growth of our business. Moreover, if we are unable to attract and retain qualified healthcare professionals, we may have to limit the number of clients for whom we can provide any of our prospective products or services.

We may be dependent on payments from Medicare and Medicaid. Changes in the rates of methods governing these payments for our prospective products or services, or delays in such payments, could adversely affect our prospective revenue.

A large portion of our revenue may consist of payments from Medicare and Medicaid programs. We cannot assure you that Medicare and Medicaid will continue to pay in the same manner or in the same amount that they currently do. Any reductions in amounts paid by government programs for our prospective products or services or changes in methods or regulations governing payments would adversely affect our potential revenue. Additionally, delays in any such payments, whether as a result of disputes or for any other reason, would also adversely affect our potential revenue.

If our costs were to increase more rapidly than payment adjustments we receive from Medicare, Medicaid or other third-party payors for any of our potential products or services, our revenue could be negatively impacted.

We may receive fixed payments for our prospective products or services based on the level of service or care that we provide. Accordingly, our revenue may be largely dependent on our ability to manage costs of providing any products or services and to maintain a client base. We may become susceptible to situations where our clients may require more extensive and therefore more expensive products or services than we may be able to profitably deliver. Although Medicare, Medicaid and certain third-party payors currently provide for an annual adjustment of various payment rates based on the increase or decrease of the medical care expenditure category of the Consumer Price Index, these increases have historically been less than actual inflation. If these annual adjustments were eliminated or reduced, or if our costs of providing our products or services increased more than the annual adjustment, any revenue stream we may generate would be negatively impacted.

We may depend on payments from third-party payors, including managed care organizations. If these payments are reduced, eliminated or delayed, our prospective revenues could be adversely affected.

We may be dependent upon private sources of payment for any of our potential products or services. Any amounts that we may receive in payment for such products and services may be adversely affected by market and cost factors as well as other factors over which we have no control, including regulations and cost containment and utilization decisions and reduced reimbursement schedules of third-party payors. Any reductions in such payments, to the extent that we could not recoup them elsewhere, would have a material adverse effect on our prospective business and results of operations. Additionally, delays in any such payments, whether as a result of disputes or for any other reason, would have a material adverse effect on our prospective business and results of operations.

Medical reviews and audits by governmental and private payors could result in material payment recoupments and payment denials.

Medicare fiscal intermediaries and other payors may periodically conduct pre-payment or post-payment medical reviews or other audits of our prospective products or services. In order to conduct these reviews, the payor would request documentation from us and then review that documentation to determine compliance with applicable rules and regulations, including the documentation of any products or services that we might provide. We cannot predict whether medical reviews or similar audits by federal or state agencies or commercial payors of such products or services will result in material recoupments or denials, which could reduce our revenues and cause damage to our business reputation.

The FDA and state and foreign regulatory agencies have promulgated regulations that will affect our existing or potential products after consummating an acquisition.

The business activities we may engage in following a business combination, including medical device manufacturing and drug development or testing, are subject to rigorous regulatory requirements at the federal, state and foreign levels, which lead to burdensome reporting requirements or potential sanctions. See the section below entitled “Proposed Business—Regulation of the Healthcare Sector.”

The regulatory requirements applicable to our products may be modified in the future. We cannot determine what effect changes in regulations or statutes or legal interpretations may have on a product in the future. Changes could require alterations to manufacturing methods, expanded or different labeling, monitoring mechanisms, the recall, replacement or withdrawal of certain products, additional record keeping and expanded documentation of the properties of certain products or their effects on patients, and new scientific substantiation. Any changes or new legislation could have a material adverse effect on our ability to develop and sell new products and, therefore, our ability to generate revenue and cash flow from them.

Additionally, our potential products may be subject to regulation by similar agencies in other states and foreign countries. Compliance with such laws or regulations, including any new laws or regulations in connection any potential products developed by us, might impose additional costs on us or marketing impediments on such products which could adversely affect our revenues and increase our expenses. The FDA and state authorities have broad enforcement powers. Our failure to comply with applicable regulatory requirements could result in enforcement action by the FDA or state agencies, which may include any of the following sanctions:

The FDA can impose civil and criminal enforcement actions and other penalties on us if we were to fail to comply with stringent FDA regulations.

Medical device manufacturing facilities must maintain records, which are available for FDA inspectors documenting that the appropriate manufacturing procedures were followed. Should we acquire such a facility as a result of a business combination, the FDA would have authority to conduct inspections of such a facility. Labeling and promotional activities are also subject to scrutiny by the FDA and, in certain instances, by the Federal Trade Commission. Any failure by us to take satisfactory corrective action in response to an adverse inspection or to comply with applicable FDA regulations could result in enforcement action against us, including a public warning letter, a shutdown of manufacturing operations, a recall of our products, civil or criminal penalties or other sanctions. From time to time, the FDA may modify such requirements, imposing additional or different requirements which could require us to alter our business methods which could potentially result in increased expenses.

The following table sets forth the proceeds we estimate to receive from this offering:

We intend to use the proceeds from the sale of the units to acquire one or more operating businesses in the healthcare-related sector.

Of the net proceeds, $89,595,000, or $103,195,000 if the underwriters’ over-allotment option is exercised in full, will be placed in a trust account at JPMorgan Chase Bank, N.A. The proceeds will not be released from the trust account until the earlier of the completion of a business combination or our liquidation. The proceeds held in the trust account may be used as consideration to pay the sellers of a target business with which we ultimately complete a business combination. Any amounts not paid as consideration to the sellers of the target business may be used to finance the costs of a business combination, future operations and/or subsequent acquisitions.

We intend to use the excess working capital (approximately $850,000) for director and officer liability insurance premiums (approximately $100,000), annual retainers for certain of our officers and directors (approximately $500,000) and repayment of the loan from our initial stockholder (approximately $60,000), with the balance of $190,000 being held in reserve. We have reserved approximately $150,000 for reimbursement of internal expenses incurred in connection with conducting due diligence reviews of prospective target businesses, including any out-of-pocket expenses incurred by our initial stockholder in connection with activities on our behalf. We expect that internal due diligence of prospective target businesses will be performed by some or all of

our officers and directors. We have reserved approximately $650,000 for legal, accounting and other third party expenses, such as engaging market research and valuation firms, as well as other expenses of structuring and negotiating business combinations, including the making of a down payment or the payment of exclusivity or similar fees and expenses.

We may not use all of the proceeds in the trust in connection with a business combination, either because the consideration for the business combination is less than the proceeds in trust or because we finance a portion of the consideration with our capital stock or debt securities. In that event, the proceeds held in the trust account as well as any other net proceeds not expended will be used to finance the costs of a business combination, future operations and/or subsequent acquisitions.

Our initial stockholder has made a loan to us of approximately $60,000. This loan and the proceeds of the sale of shares to our initial stockholder were used to pay certain expenses of the offering including the SEC registration fee of $38,351 and the NASD filing fee of $33,083. This loan will be repaid upon the consummation of the offering out of the net proceeds not placed in trust.

The net proceeds of this offering that are not immediately required for the purposes set forth above will be invested in a money market fund, selected by us, which invests principally in short-term securities issued or guaranteed by the United States having a rating in the highest investment category granted thereby by a recognized credit rating agency at the time of acquisition, so that we are not deemed to be an investment company under the Investment Company Act of 1940. The interest income derived from investment of the net proceeds not held in trust during this period will be used to defray our general and administrative expenses, as well as costs relating to compliance with securities laws and regulations, including associated professional fees, until a business combination is completed.

We believe that, upon consummation of this offering, we will have sufficient available funds to operate for at least the next 24 months, assuming that a business combination is not consummated during that time.

No cash compensation will be paid to our initial stockholder for services rendered to us prior to or in connection with the consummation of the business combination. Each of our officers and directors, other than Sean McDevitt and Pat LaVecchia will receive a percentage interest in our initial stockholder. Healthcare Acquisition Parent, LLC, of which William Bischoff, a managing director of FTN Midwest Securities Corp., is the manager and of which FTN Midwest Securities Corp. is the sole member, currently holds a 100% interest in our initial stockholder. At the consummation of the offering, Healthcare Acquisition Parent, LLC will hold a 66% interest in our initial stockholder (all or any part of such interest may be allocated to current or future members of our management or to management of FTN Midwest Securities Corp. or its affiliates). These interests in our initial stockholder, the interests in Healthcare Acquisition Parent, LLC held by FTN Midwest Securities Corp., and the interest in the shares of our common stock held by our initial stockholder will be subject to lock-up agreements restricting their sale until six months after a business combination is completed. Our chief executive officer, chief financial officer, and each of our independent directors will receive an annual retainer of $50,000. John Voris, our chief executive officer and a director, will receive an additional $50,000 annual retainer for his services as a director. Our initial stockholder, its members and their affiliates will receive reimbursement for any out-of-pocket expenses incurred by them in connection with activities on our behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations. Since the role of present management after a business combination is uncertain, we have no ability to determine what remuneration, if any, will be paid to those persons after a business combination.

A public stockholder will be entitled to receive funds, on a pro rata basis, from the trust account (including interest earned on the trust account) only in the event of our liquidation upon our failure to complete a business combination within the time frame provided in this prospectus or if that public stockholder were to seek to convert such shares into cash in connection with a business combination which the public stockholder previously voted against and which we actually consummate. In no other circumstances will a public stockholder have any right or interest of any kind to or in the trust account.

The following table sets forth our capitalization at September 15, 2005 and as adjusted to give effect to the sale of our units in this offering and the application of the estimated net proceeds derived from the sale of our units (assuming no exercise of the underwriters’ over-allotment option):

The difference between the public offering price per share of common stock, assuming no value is attributed to the warrants included in the units, and the pro forma net tangible book value per share of our common stock after this offering constitutes the dilution to investors in this offering. Net tangible book value per share is determined by dividing our net tangible book value, which is our total tangible assets less total liabilities (including the value of common stock which may be converted into cash), by the number of outstanding shares of our common stock.

At September 15, 2005, our net tangible book value was approximately $24,944, or approximately $(.006) per share of common stock. After giving effect to the sale of 16,666,667 shares of common stock included in the units (but excluding shares issuable upon exercise of the warrants included in the units), and the deduction of underwriting discounts and estimated expenses of this offering, our pro forma net tangible book value (as decreased by the value of 3,331,667 shares of common stock which may be converted into cash) at September 15, 2005 would have been approximately $73,575,576 or $4.20 per share, representing an immediate increase in net tangible book value of $4.20 per share to our initial stockholder and an immediate dilution of $1.80 per share or 30% to new investors not exercising their conversion rights.

The following table illustrates the dilution to the new investors on a per-share basis, assuming no value is attributed to the warrants included in the units:

Our pro forma net tangible book value after this offering has been reduced by approximately $17,924,368 because if we effect a business combination, the conversion rights to the public stockholders may result in the conversion into cash of up to approximately 19.99% of the aggregate number of the shares sold in this offering at a per-share conversion price equal to the amount in the trust account calculated as of two business days prior to the consummation of the proposed business combination, inclusive of any interest, divided by the number of shares sold in this offering.

The following table sets forth information with respect to our initial stockholder and the new investors:

The pro forma net tangible look value after the offering is calculated as follows:

We were formed on August 15, 2005, as a blank check company for the purpose of acquiring, through a merger, capital stock exchange, asset acquisition or other similar business combination, one or more operating businesses in the healthcare sector. We do not have any specific business combination under consideration, and neither we, nor any representative acting on our behalf, has had any contacts with any target businesses regarding a business combination, nor taken any direct or indirect actions to locate or search for a target business regarding a business combination. We intend to use cash derived from the proceeds of this offering, our capital stock, debt or a combination of cash, capital stock and debt, to finance the costs of a business combination, future operations and/or subsequent acquisitions.

The issuance of additional capital stock, including upon conversion of any convertible debt securities we may issue, or the incurrence of debt could have material consequences on our business and financial condition. The issuance of additional shares of our capital stock (including upon conversion of convertible debt securities):

To date, our efforts have been limited to organizational activities. We have neither engaged in any operations nor generated any revenues to date.

We estimate that the net proceeds from the sale of the units will be approximately $91,475,000 (or $105,275,000 if the underwriters’ over-allotment option is exercised in full), after deducting offering expenses of approximately $521,434 and underwriting discounts of approximately $8,000,000 (or $9,200,000 if the underwriters’ over-allotment option is exercised in full), including $1,000,000 ($1,150,000 of the underwriters’ over-allotment option is exercised in full) evidencing the underwriters’ non-accountable expense allowance of 1% of the gross proceeds. Of this amount, $89,595,000, or $103,195,000 if the underwriters’ over-allotment option is exercised in full, will be held in trust and the remaining $1,880,000, or $2,080,000 if the underwriters’ over-allotment is exercised in full, will not be held in trust. We will use substantially all of the net proceeds of this offering to acquire one or more operating businesses, including identifying and evaluating prospective acquisition candidates, selecting one or more operating businesses, and structuring, negotiating and consummating the business combination. However, we may not use all of the proceeds in the trust in connection

with a business combination, either because the consideration for the business combination is less than the proceeds in trust or because we finance a portion of the consideration with our capital stock or debt securities. In that event, the proceeds held in the trust account as well as any other net proceeds not expended will be used to finance the costs of a business combination, future operations and/or subsequent acquisitions.

We believe that, upon consummation of this offering and payment of certain expenses in connection with the offering, the funds available to us outside of the trust account will be sufficient to allow us to operate for the next 24 months, assuming that a business combination is not consummated during that time. Over this time period, we anticipate making the following expenditures:

We do not believe we will need additional financing following this offering in order to meet the expenditures required for operating our business. However, we may need to obtain additional financing to the extent such financing is required to consummate a business combination, in which case we may issue additional securities or incur debt in connection with such business combination.

We have also agreed to sell to FTN Midwest Securities Corp., for $100, an option to purchase up to a total of 958,333 units, each consisting of one share of common stock and two warrants, at $7.50 per unit, commencing on the later of the consummation of a business combination and one year after the date of this prospectus and expiring five years after the date of this prospectus. The warrants underlying such units will have terms that are identical to those being issued in this offering, with the exception of the exercise price, which will be set at $7.50 per warrant. The purchase option may be transferred, in whole or in part, to any subsidiary or affiliate of FTN Midwest Securities Corp., upon notice to us, or to any third party transferee, subject to our consent. The purchase option will also contain a cashless exercise feature that allows the holder of the purchase option to receive units on a net exercise basis. In addition, the purchase option will provide for registration rights that will permit the holder of the purchase option to demand that a registration statement be filed with respect to all or any part of the securities underlying the purchase option within five years of the date of this prospectus. Further, the holder of the purchase option will be entitled to piggy-back registration rights in the event we undertake a subsequent registered offering within seven years of the date of this prospectus. The warrants and shares of common stock FTN Midwest Securities Corp. may obtain pursuant to this option will be subject to a lock-up agreement restricting their sale until six months after completion of a business combination.

We are a recently organized Delaware blank check company formed for the purpose of acquiring, through a merger, capital stock exchange, asset acquisition or other similar business combination, one or more operating businesses in the healthcare sector.

According to the National Coalition on Health Care, U.S. healthcare spending reached $1.7 trillion in 2003, the latest year for which data is available, approximately 4.3 times the amount spent on national defense. According to the Centers for Medicare & Medicaid, total U.S. healthcare expenditures are projected to increase to $3.4 trillion in 2013, with the annual growth rate averaging about 7%. U.S. healthcare spending, calculated at 15% of GDP based on statistics from the Centers for Medicare & Medicaid and projected to be more than 18% of GDP in 2013 according to the California HealthCare Foundation, is larger than that of every other developed nation in total size, as a percentage of GDP, and on a per-capita basis according to Plunkett’s Health Care Industry Almanac. In fact, according to Plunkett’s Health Care Industry Almanac, per capita spending is twice the average of that of member countries of the Organization for Economic Cooperation and Development. Moreover, according to Plunkett’s Health Care Industry Almanac, investors are supporting this growth, investing $4.8 billion in venture investment into U.S. healthcare companies in the first nine months of 2004 alone. Within this industry we believe there are numerous niche sectors each with potential markets totaling in the hundreds of millions of dollars. While some of these sectors are serviced by large traditional healthcare institutions, we believe many are nascent with significant opportunities for fast-moving, smaller companies. The Centers for Medicare and Medicaid Services anticipates the industry will grow at a compounded annual growth rate (CAGR) of 7.2% from 2004 to 2013, reaching $3.4 trillion. This growth outpaces the forecasted U.S. GDP CAGR of 5.2% for the same time frame. At these respective rates, healthcare costs will comprise 18% of the GDP in 2013. Factors contributing to this growth include:

While the market has grown, it has also faced substantial challenges and undergone significant changes. Rising costs have placed increased pressure on payors, providers, and consumers to find lower-cost healthcare solutions. Legislation has reformed Medicare to give private insurers a greater role in insuring the elderly and to provide prescription drug benefits for seniors. Other legislative efforts have targeted drug pricing by attempting to find ways to encourage the manufacture of generics. New technology and services are increasing the efficiency of all aspects of the healthcare industry, from physicians to payors.

In recent years, the healthcare industry has capitalized on many remarkable advances in medical technology, including breakthroughs in computing, communications, small-incision surgery, drug therapies, diagnostics and instruments. Meanwhile, more emphasis is being placed on the use of computers and advanced telecommunication technology in many phases of hospital operations and patient care, often in conjunction with complex equipment to diagnose and improve patients’ conditions. With respect to investment in IT, the healthcare industry lagged behind almost all other business sectors in 2003, spending just under 4% of its revenue on IT, in contrast to many other industries that have been averaging 5% to 8%. However, this is starting to change. Gartner, a major research firm, projects healthcare industry spending on IT to rise from $34 billion in 2001 to nearly $48 billion in 2006—the second-fastest area for IT growth after the Federal Government. A recent survey by the Health Information Management and Systems Society found that 60% of U.S. hospitals are utilizing, installing or planning to install systems to handle electronic records.

The U.S. Department of Health & Human Services estimated that a national electronic health information network could save about $140 billion yearly, or 8% of the nation’s health expenditures. This is due to the fact that vast amounts of time and money are wasted on redundant paperwork, billing errors, duplicated tasks and mistreatment of patients due to lack of complete health information at the point of treatment.

The large number of growth factors and regulatory changes creates an entrepreneur’s market in which companies that can capitalize on the growth and changing environment will prosper. While the healthcare market is dominated by some of the largest companies in the U.S., their ability to adapt to meet the industry’s growth and changing paradigms has been hampered by bureaucracy, heavy R&D costs, and increased litigation. In this type of environment, middle market companies can often react faster to changes and take advantage of the market opportunities.

Through our management team and our directors, we have extensive contacts and sources in the healthcare sector from which we believe that we will be able to generate acquisition opportunities. These contacts and sources include private equity and venture capital funds, public and private companies, investment bankers, attorneys and accountants. The members of our management team intend to maintain relationships with a significant number of private equity and venture capital funds and public and private companies.

While we expect to seek to effect additional business combinations, our initial business acquisition must be with one or more operating businesses whose fair market value is, either individually or collectively, at least equal to 80% of our net assets at the time of such acquisition. We do not have any specific business combination under consideration, and neither we, nor any representative acting on our behalf, has had any contacts with any target businesses regarding a business combination, nor taken any direct or indirect actions to locate or search for a target business regarding a business combination.

The development, testing, production and marketing of any of our potential products that we may manufacture, market or sell following a business combination may be subject to regulation by the FDA as “devices” under the 1976 Medical Device Amendments to the Federal Food, Drug and Cosmetic Act, as amended. Before a new medical device, or a new use of, or claim for, an existing product can be marketed in the United States, it must first receive either 510(k) clearance or pre-market approval from the FDA, unless an exemption applies. Either process can be expensive and lengthy. The FDA’s 510(k) clearance process usually takes from three to twelve months, but it can take longer and is unpredictable. The process of obtaining

pre-market approval is much more costly and uncertain than the 510(k) clearance process and it generally takes from one to three years, or even longer, from the time the application is filed with the FDA.

As a result, we may be required to comply with QSR requirements and if we fail to comply with these requirements, we may need to find another company to manufacture any such devices which could delay the shipment of our potential product to our customers.

The FDA requires producers of medical devices to obtain FDA clearance or approval prior to commercialization in the United States. Testing, preparation of necessary applications and the processing of those applications by the FDA is expensive and time consuming. We do not know if the FDA would act favorably or quickly in making such reviews, and significant difficulties or costs may potentially be encountered by us in any efforts to obtain FDA clearance or approval. The FDA may also place conditions on clearances and approvals that could restrict commercial applications of such products. Product approvals may be withdrawn if compliance with regulatory standards is not maintained or if problems occur following initial marketing. Delays imposed by the FDA clearance or approval process may materially reduce the period during which we have the exclusive right to commercialize any potential patented products. We may make modifications to any potential devices and may make additional modifications in the future that we may believe do not or will not require additional clearances or approvals. If the FDA should disagree, and require new clearances or approvals for the potential modifications, we may be required to recall and to stop marketing the potential modified devices. We also may be subject to Medical Device Reporting regulations, which would require us to report to the FDA if our products were to cause or contribute to a death or serious injury, or malfunction in a way that would likely cause or contribute to a death or serious injury.

The development, testing, production and marketing of any of our potential products that we may manufacture, market or sell following a business combination may be subject to regulation by the FDA as “drugs.” All “new drugs” must be the subject of an FDA-approved new drug application (NDA) and all new biologics products must be the subject of a biologics license application (BLA) before they may be marketed in the United States. All generic equivalents to previously approved drugs or new dosage forms of existing drugs must be the subject of an FDA-approved abbreviated new drug application (ANDA) before they may be marketed in the United States. In all cases, the FDA has the authority to determine what testing procedures are appropriate for a particular product and, in some instances, has not published or otherwise identified guidelines as to the appropriate procedures. The FDA has the authority to withdraw existing NDA, BLA and ANDA approvals and to review the regulatory status of products marketed under its enforcement policies. The FDA may require an approved NDA, BLA, or ANDA for any drug or biologic product marketed to be recalled or withdrawn under its enforcement policy if new information reveals questions about the drug or biologic’s safety or effectiveness. All drugs must be manufactured in conformity with current good manufacturing practice regulations (GMPs) and drugs and biologics subject to an approved NDA, BLA, or ANDA must be manufactured, processed, packaged, held and labeled in accordance with information contained in those approvals. The required product testing and approval process for new drugs and biologics ordinarily takes several years and requires the expenditure of substantial resources. Testing of any product under development may not result in a commercially-viable product. Even after such time and expenses, regulatory approval by the FDA may not be obtained for any products developed. In addition, delays or rejections may be encountered based upon changes in FDA policy during the period of product development and FDA review. Any regulatory approval may impose limitations in the indicated use for the product. Even if regulatory approval is obtained, a marketed product, its manufacturer and its manufacturing facilities are subject to continual review and periodic inspections. Subsequent discovery of previously unknown problems with a product, manufacturer or facility may result in restrictions on the product or manufacturer, including withdrawal of the product from the market.

Even if required FDA approval has been obtained with respect to a new drug or biologic product, foreign regulatory approval of a product must also be obtained prior to marketing the product internationally. Foreign approval procedures vary from country to country and the time required for approval may delay or prevent marketing. The clinical testing requirements and the time required to obtain foreign regulatory approvals may differ from that required for FDA approval. Although there is now a centralized European Union approval mechanism for new pharmaceutical products in place, each European Union member state may nonetheless impose its own procedures and requirements, many of which are time consuming and expensive, and some European Union member states require price approval as part of the regulatory approval process. Thus, there can be substantial delays in obtaining required approval from both the FDA and foreign regulatory authorities.

We are not presently engaged in, and we will not engage in, any substantive commercial business for an indefinite period of time following this offering. We intend to use cash derived from the proceeds of this offering, our capital stock, debt or a combination of these to effect a business combination involving one or more operating businesses in the healthcare-related sector. Although substantially all of the net proceeds of this offering are intended to be generally applied toward effecting a business combination as described in this prospectus, the proceeds are not otherwise being designated for any more specific purposes. Accordingly, prospective investors in this offering will make their decision whether to invest in us without an opportunity to evaluate the specific merits or risks of any one or more business combinations. A business combination may involve the acquisition of, or merger with, one or more operating businesses which do not need substantial additional capital but which desire to establish a public trading market for their shares, while avoiding what they may deem to be adverse consequences of undertaking a public offering itself. We believe these include certain time delays, significant expense, loss of voting control and compliance with various federal and state securities laws. In the alternative, a business combination may involve one or more companies which may be financially unstable or in the early stages of development or growth.

We do not have any specific business combination under consideration and neither we, nor any representative acting on our behalf, has had any contacts with any target businesses regarding a business combination, nor taken any direct or indirect actions to locate or search for a target business regarding a business combination. Subject to the requirement that our initial business combination must be with one or more operating businesses in the healthcare sector that, collectively, have a fair market value of at least 80% of our net assets at the time of the acquisition, as described below in more detail, we will have virtually unrestricted flexibility in identifying and selecting prospective acquisition candidates in the healthcare sector. Accordingly, there is no basis for investors in this offering to evaluate the possible merits or risks of the particular industry in the healthcare sector in which we may ultimately operate or the target businesses with which we may ultimately complete a business combination.

We anticipate that acquisition candidates may be brought to our attention by FTN Midwest Securities Corp., or from various unaffiliated sources, including securities broker-dealers, investment bankers, venture capitalists, bankers and other members of the financial community, who may present solicited or unsolicited proposals. We have entered into agreements with FTN Midwest Securities Corp. and certain officers and directors, under the terms of which each of them has agreed to present to us for our consideration any opportunity to acquire all or substantially all of the outstanding equity securities of, or otherwise acquire a controlling equity interest in, an operating business in the healthcare, or a healthcare-related, sector, provided that they are under no obligation to present to us any opportunity involving a business in the healthcare, or a healthcare-related, sector seeking a strategic combination with another operating business in the healthcare, or a healthcare-related, sector. The terms

of these agreements do not obligate these individuals or FTN Midwest Securities Corp. to present any opportunities to us for consideration prior to presenting such opportunities to any other person or entity. Our other officers and directors and their affiliates intend to solicit such proposals, and may also bring to our attention acquisition candidates. In addition, we anticipate that the positions held and contacts maintained by the members of our management within the financial community will generate other unsolicited proposals. We do not anticipate receiving any unsolicited proposals with respect to business combinations with prospective target businesses until we have completed this offering. In addition, we will not evaluate any unsolicited proposals that we may receive with respect to any business combinations with prospective target businesses until we have completed this offering.

Subject to the requirement that our initial business combination must be with one or more operating businesses that, individually or collectively, have a fair market value of at least 80% of our net assets at the time of such acquisition, our management will have virtually unrestricted flexibility in identifying and selecting prospective target businesses in the healthcare sector. However, subject to fluctuations in the economy in general, and the healthcare sector in particular, we currently intend to concentrate on prospective target companies, in each case assuming an acquisition value that is equivalent to the available proceeds held in the trust account. We expect that our management will diligently review all of the proposals we receive with respect to prospective target businesses. In evaluating prospective target businesses, our management expects to consider, among other factors, the following:

These criteria are not intended to be exhaustive. Any evaluation relating to the merits of a particular business combination with one or more operating businesses will be based, to the extent relevant, on the above factors as well as other considerations deemed relevant by our management in effecting a business combination consistent with our business objective. In evaluating prospective target businesses, we intend to conduct an extensive due diligence review which will encompass, among other things, meetings with incumbent management and inspection of facilities, as well as review of financial and other information which will be made available to us.

We will endeavor to structure a business combination so as to achieve the most favorable tax treatment to us, the target businesses and their stockholders, as well as our stockholders. We cannot assure you, however, that the Internal Revenue Service or appropriate state tax authority will agree with our tax treatment of the business combination.

The time and costs required to select and evaluate target businesses and to structure and complete the business combination cannot presently be ascertained with any degree of certainty. Any costs incurred with respect to the identification and evaluation of prospective target businesses with which a business combination is not ultimately completed will result in a loss to us and reduce the amount of capital available to otherwise complete a business combination.

The initial target businesses that we acquire must have a fair market value, individually or collectively, equal to at least 80% of our net assets at the time of such acquisition. The fair market value of such businesses will be determined by our board of directors based upon standards generally accepted by the financial community, such as actual and potential sales, earnings and cash flow and book value. If our board is not able to determine on its own that the target businesses have a sufficient fair market value or if a conflict of interest exists with respect to such determination, we will obtain an opinion from an unaffiliated, independent investment banking firm which is a member of the National Association of Securities Dealers, Inc., or NASD, with respect to the satisfaction of such criteria. However, we will not be required to obtain an opinion from an investment banking firm as to the fair market value of the target business if our board of directors independently determines that the target businesses have sufficient fair market value. We expect that any such opinion will be included in our proxy solicitation materials furnished to our stockholders in connection with a business combination, and that such independent investment banking firm will be a consenting expert.

The net proceeds from this offering will provide us with approximately $91,475,000 which we may use to complete a business combination. While we may seek to effect a business combination with more than one target business, our initial business acquisition must be with one or more operating businesses whose fair market value, individually or collectively, is at least equal to 80% of our net assets at the time of such acquisition. At the time of our initial business combination, we may not be able to acquire more than one target business because of various factors, including insufficient financing or the difficulties involved in consummating the contemporaneous acquisition of more than one operating company; therefore, it is possible that we will have the ability to complete a business combination with only a single operating business which may only have a limited number of products or services. The resulting lack of diversification may:

In this case, we will not be able to diversify our operations or benefit from the possible spreading of risks or offsetting of losses, unlike other entities which have the resources to complete several business combinations in different industries or different areas of a single industry so as to diversify risks and offset losses. Further, the prospects for our success may be entirely dependent upon the future performance of the initial target business or businesses we acquire.

In addition, since our business combination may entail the contemporaneous acquisition of several operating businesses at the same time and may be with different sellers, we will need to convince such sellers to agree that the purchase of their businesses is contingent upon the simultaneous closings of the other acquisitions.

As noted above, we expect to effect our initial business combination through the acquisition of a single business, but we reserve the right to acquire more than one business in contemporaneous acquisitions if our

board of directors determines that such a course is in our best interest. Completing our initial business combination through more than one acquisition would likely result in increased costs as we would be required to conduct a due diligence investigation of more than one business and negotiate the terms of the acquisition with multiple sellers. In addition, due to the difficulties involved in consummating multiple acquisitions concurrently, our attempt to complete our initial business combination in this manner would increase the chance that we would be unable to successfully complete our initial business combination in a timely manner.

Although we intend to closely scrutinize the management of prospective target businesses when evaluating the desirability of effecting a business combination with those businesses, we cannot assure you that our assessment of the target business’s management will prove to be correct. In addition, we cannot assure you that the future management will have the necessary skills, qualifications or abilities to manage a public company intending to embark on a program of business development. Further, we cannot ascertain the future role of our officers and directors, if any, in the target businesses. While it is possible that one or more of our officers and directors will remain associated with us in some capacity following a business combination, it is unlikely that any of them will devote their full efforts to our affairs subsequent to a business combination. Moreover, we cannot assure you that our officers and directors will have significant experience or knowledge relating to the operations of the particular target businesses acquired.

Following a business combination, we may seek to recruit additional managers to supplement the incumbent management of the acquired businesses. We cannot assure you that we will have the ability to recruit additional managers, or that additional managers will have the requisite skills, knowledge or experience necessary to enhance the incumbent management.

Prior to the completion of a business combination, we will submit the transaction to our stockholders for approval, even if the nature of the acquisition is such as would not ordinarily require stockholder approval under applicable state law. In connection with seeking stockholder approval of a business combination, we will furnish our stockholders with proxy solicitation materials prepared in accordance with the Securities Exchange Act of 1934, which, among other matters, will include a description of the operations of the target business and certain required financial information regarding the business.

In connection with the vote required for our initial business combination, our initial stockholder has agreed to vote the shares of common stock owned by it immediately before the consummation of this offering in the same way as the holders of the majority of the shares sold to the public in this offering and any other public offering. We will proceed with the business combination only if a majority of the shares of common stock voted by the public stockholders are voted in favor of the business combination and public stockholders owning less than 20% of the shares sold in this offering both vote against the business combination and exercise their conversion rights.

At the time we seek stockholder approval of our initial business combination, we will offer each public stockholder the right to have such stockholder’s shares of common stock converted to cash if the stockholder votes against the business combination and the business combination is approved and completed. The actual per-share conversion price will be equal to the amount in the trust account, inclusive of any interest (calculated as of two business days prior to the consummation of the proposed business combination), divided by the number of shares of common stock sold in this offering. Without taking into any account interest earned on the trust account, the initial per-share conversion price would be $5.38, or $.62 less than the per-unit offering price of $6.00. An eligible stockholder may request conversion at any time after the mailing to our stockholders of the proxy statement and prior to the vote taken with respect to a proposed business combination at a meeting held for

that purpose, but the request will not be granted unless the stockholder votes against the business combination and the business combination is approved and completed. Any request for conversion, once made, may be withdrawn at any time up to the date of the meeting. It is anticipated that the funds to be distributed to stockholders entitled to convert their shares who elect conversion will be distributed promptly after completion of a business combination. Public stockholders who convert their stock into their share of the trust account still have the right to exercise the warrants that they received as part of the units. We will not complete any business combination if public stockholders, owning 20% or more of the shares sold in this offering, both vote against a business combination, and, subsequently, exercise their conversion rights. Our initial stockholder, members of our management team and the beneficial owners of our initial stockholder and of Healthcare Acquisition Parent, LLC, including FTN Midwest Securities Corp., will agree not to purchase any additional shares of common stock, whether as part of this offering or otherwise, prior to the completion of a business combination and will therefore have no conversion rights. This agreement will not apply to the acquisition of securities by FTN Midwest Securities Corp. pursuant to the underwriting agreement (including the over-allotment option) and will allow FTN Midwest Securities Corp. to engage in stabilizing transactions and passive market-making as described in the section entitled “Underwriting”.

If we do not complete a business combination within 18 months after the consummation of this offering, or within 24 months if the extension criteria described below have been satisfied, we will be liquidated and will distribute to all of our public stockholders, in proportion to their respective equity interests, an aggregate sum equal to the amount in the trust account, inclusive of any interest, plus any remaining net assets. Our initial stockholder will not have the right to participate in any liquidation distribution occurring upon our failure to consummate a business combination with respect to those shares of common stock acquired prior to this offering and our initial stockholder, members of our management team and the beneficial owners of our initial stockholder and of Healthcare Acquisition Parent, LLC, including FTN Midwest Securities Corp., will agree not to purchase any additional shares of common stock, whether as part of this offering or otherwise, prior to the completion of a business combination and will, therefore, have no right to participate in a liquidation distribution. This agreement will not apply to the acquisition of securities by FTN Midwest Securities Corp. pursuant to the underwriting agreement (including the over-allotment option) and will allow FTN Midwest Securities Corp. to engage in stabilizing transactions and passive market-making as described in the section entitled “Underwriting”. There will be no distribution from the trust account with respect to our warrants, and all rights with respect to our warrants will effectively cease upon our liquidation.

If we were to expend all of the net proceeds of this offering, other than the proceeds deposited in the trust account, and without taking into account interest, if any, earned on the trust account, the initial per-share liquidation price would be $5.38, or $0.62 less than the per-unit offering price of $6.00. The proceeds deposited in the trust account could, however, become subject to the claims of our creditors which could be prior to the claims of our public stockholders. We cannot assure you that the actual per-share liquidation price will not be less than $5.38, plus interest, due to claims of creditors.

If we enter into a definitive agreement to complete a business combination prior to the expiration of 18 months after the consummation of this offering, but are unable to complete the business combination within the 18-month period, then we will have an additional six months in which to complete the business combination contemplated by the definitive agreement. If we are unable to do so by the expiration of the 24-month period from the consummation of this offering, we will then liquidate. Upon notice from us, the trustee of the trust account will commence liquidating the investments constituting the trust account and will turn over the proceeds to our transfer agent for distribution to our public stockholders. We anticipate that our instruction to the trustee would be given promptly after the expiration of the 18-month or 24-month period, as applicable.

Our public stockholders will be entitled to receive funds from the trust account only in the event of our liquidation or if the stockholders seek to convert their respective shares into cash upon the consummation of a business combination which the stockholder voted against and which is actually completed by us. In no other circumstances, except as required by applicable law, will a stockholder have any right or interest of any kind to or in the trust account.

Our Amended and Restated Certificate of Incorporation sets forth certain requirements and restrictions relating to this offering that apply to us until the consummation of a business combination. Specifically, our Amended and Restated Certificate of Incorporation provides, among other things, that:

In identifying, evaluating and selecting target businesses, we may encounter intense competition from other entities having a business objective similar to ours. Many of these entities are well established and have extensive experience identifying and effecting business combinations directly or through affiliates. Many of these competitors possess greater financial, technical, human and other resources than us. While we believe there are numerous potential target businesses that we could acquire with the net proceeds of this offering, our ability to compete in acquiring certain sizable target businesses will be limited by our available financial resources. This inherent competitive limitation gives others an advantage over us in pursuing the acquisition of target businesses. Further:

Any of these factors may place us at a competitive disadvantage in successfully negotiating a business combination. Our management believes, however, that our status as a public entity and potential access to the United States public equity markets may give us a competitive advantage over privately-held entities having a similar business objective as ours in acquiring a target business on favorable terms.

If we succeed in effecting a business combination in the healthcare sector, there will be, in all likelihood, intense competition from competitors of the target businesses. In particular, certain industries which experience

rapid growth frequently attract an increasingly larger number of competitors, including competitors with increasingly greater financial, marketing, technical, human and other resources than the initial competitors in the industry. The degree of competition characterizing the industry of any prospective target business cannot presently be ascertained. We cannot assure you that, subsequent to a business combination, we will have the resources to compete effectively, especially to the extent that the target businesses are in high-growth industries.

We do not own any real estate or other physical properties materially important to our operation. Our executive offices, which we use pursuant to an agreement with FTN Midwest Securities Corp., are located at 350 Madison Avenue, New York, NY 10017. We believe that our office facilities are suitable and adequate for our business as it is presently conducted.

We currently have three officers, two of whom, John Voris and Pat LaVecchia, are also members of our board of directors. John Voris will receive a $50,000 annual retainer for his services as chief executive officer and a $50,000 annual retainer for his services as a director for a total of $100,000 per year. Erin Enright will receive a $50,000 annual retainer for her services as chief financial officer. Pat LaVecchia will receive no compensation from us. Mr. Voris will hold a 14% interest in our initial stockholder. Ms. Enright will hold a 4% interest in our initial stockholder. We have no other employees. These individuals are not obligated to devote any specific number of hours to our matters and intend to devote only as much time as they deem necessary to our affairs. We do not intend to have any full time employees prior to the consummation of a business combination. Pat LaVecchia, our Secretary and Director, is a managing director of FTN Midwest Securities Corp.

We will register our units, common stock and warrants under the Securities Exchange Act of 1934, and have reporting obligations thereunder, including the requirement that we file annual and quarterly reports with the SEC. In accordance with the requirements of the Securities Exchange Act of 1934, our annual reports will contain financial statements audited and reported on by our independent registered public accounting firm.

We will not acquire a target business if we cannot obtain audited financial statements based on United States generally accepted accounting principles for the target business. Additionally, our management will provide stockholders with audited financial statements, prepared in accordance with generally accepted accounting principles, of the prospective businesses as part of the proxy solicitation materials sent to stockholders to assist them in assessing the business combination. Our management believes that the requirement of having available audited financial statements for the target businesses will not materially limit the pool of potential target businesses available for acquisition.

The following table compares and contrasts the terms of this offering and the terms of an offering by blank check companies under Rule 419 promulgated by the SEC assuming that the gross proceeds, underwriting discounts and underwriting expenses for a Rule 419 offering are the same as this offering and that the underwriters do not exercise their over-allotment option. None of the terms of a Rule 419 offering will apply to this offering.

Our Board of Directors intends to establish an Audit Committee, which will report to the Board of Directors. The Audit Committee will be responsible for meeting with our independent registered accounting firm regarding, among other issues, audits and adequacy of our accounting and control systems.

In addition, the Audit Committee will monitor compliance on a quarterly basis with the terms of this offering. If any noncompliance is identified, then the Audit Committee will have the responsibility to take immediately all action necessary to rectify such noncompliance or otherwise cause compliance with the terms of this offering. The Audit Committee is required to be composed entirely of independent directors.

Due to the affiliation of Messrs. McDevitt and LaVecchia with FTN Midwest Securities Corp., to the extent FTN Midwest Securities is acting as our advisor in connection with a business combination, the Audit Committee will have the sole authority to negotiate and approve the terms of such business combination, subject to the stockholder approval rights.

No member of our Board of Directors is an an “audit committee financial expert” as that term is defined under Item 401 of Regulation S-K of the Securities Exchange Act of 1934, as amended, but nonetheless, we believe the members are qualified to perform their duties.

No executive officer, director or initial stockholder, nor any affiliate thereof, has received any cash compensation for services rendered.

Each of our officers and directors, other than Sean McDevitt and Pat LaVecchia, will receive a percentage interest in our initial stockholder. John Voris will receive a 14% interest, Wayne Yetter will receive an 8% interest, Jean-Pierre Millon will receive an 8% interest and Erin Enright will receive a 4% interest. Healthcare Acquisition Parent, LLC, of which William Bischoff, a managing director of FTN Midwest Securities Corp., is the managing member, holds a 100% interest in our initial stockholder. At the time of the offering, Healthcare Acquisition Parent, LLC will hold a 66% interest in our initial stockholder (all or any part of such interest may be allocated to current or future members of our management or to management of FTN Midwest Securities Corp. or its affiliates). These interests in our initial stockholder, the interests in Healthcare Acquisition Parent, LLC held by FTN Midwest Securities Corp., and the interests in the shares of our common stock held by our initial stockholder will be subject to lock-up agreements restricting their sale until six months after a business combination is completed.

After completion of this offering, our chief executive officer, chief financial officer and each of our independent directors will receive annual compensation of $50,000. John Voris, our chief executive officer and a director, will receive an additional $50,000 annual retainer for his services as a director. No cash compensation of any kind will be paid to our initial stockholder for services rendered prior to or in connection with a business combination, but our initial stockholder and officers will receive reimbursement for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. There is no limit on the amount of these out-of-pocket expenses and there will be no review of the reasonableness of the expenses by anyone other than our board of directors, which includes persons who may seek reimbursement, or a court of competent jurisdiction if such reimbursement is challenged; provided that no proceeds held in the trust account will be used to reimburse out-of-pocket expenses prior to a business combination. If all of our directors are not deemed “independent,” we will not have the benefit of independent directors examining the propriety of expenses incurred on our behalf and subject to reimbursement, or monitoring our compliance with the terms of this offering. In addition, since the role of our current management and directors subsequent to a business combination is uncertain, we have no ability to determine what remuneration, if any, will be paid to our current management and directors after a business combination by any target businesses.

Prior to the completion of this offering, we will adopt an equity compensation plan, which we refer to as the plan. The plan generally is to be administered by the compensation committee of our board of directors, except that the full board may act at any time to administer the plan, and authority to administer any aspect of the plan may be delegated to an executive officer or any other person. The plan allows the plan administrator to grant awards of shares of our common stock or the right to receive or purchase shares of our common stock (including options to purchase common stock, restricted stock and stock units, bonus stock, performance stock, and stock appreciation rights) to our employees, directors or other persons or entities providing significant services to us or our subsidiaries, and further provides the plan administrator the authority to reprice outstanding stock options or other awards. The actual terms of an award, including the number of shares of common stock relating to the award, any exercise or purchase price, any vesting, forfeiture or transfer restrictions, the time or times of exercisability for, or delivery of, shares of common stock, are to be determined by the plan administrator and set forth in a written award agreement with the participant.

The aggregate number of shares of our common stock for which awards may be granted under the plan cannot exceed 5% of the number of shares of our common stock issued and outstanding at the time any award is granted. Awards made under the plan that have been forfeited (including our repurchase of shares of common stock subject to an award for the price, if any, paid to us for such shares of common stock, or for their par value), cancelled or have expired, will not be treated as having been granted for purposes of the preceding sentence.

The plan permits the plan administrator to make an equitable adjustment to the number, kind and exercise price per share of awards in the event of our recapitalization, reorganization, merger, spin-off, share exchange, dividend of common stock, liquidation, dissolution or other similar transaction or events. In addition, the plan administrator may make adjustments in the terms and conditions of any awards in recognition of any unusual or nonrecurring events. Our board of directors may, at any time, alter, amend, suspend or discontinue the plan. The plan will automatically terminate ten years after it has been most recently approved by our stockholders.

Prior to completion of this offering, we will adopt a code of ethics that applies to directors, officers and employees. A copy of the code of ethics will be filed as an exhibit to a subsequent amendment to the registration statement of which this prospectus forms a part.

Due to their affiliations and other professional activities, our officers and directors may encounter conflicts of interest. All ongoing and future transactions between us and any of our officers and directors or their respective affiliates will be on terms we believe to be no less favorable than are available from unaffiliated third parties and such transactions will require prior approval in each instance by a majority of our non-interested “independent” directors or the members of our board who do not have an interest in the transaction, in either case who had access, at our expense, to our attorneys or independent legal counsel.

In general, officers and directors of a corporation incorporated under the laws of the State of Delaware are required to present business opportunities to the corporation if:

Accordingly, as a result of multiple business affiliations, our officers and directors may have similar legal obligations relating to presenting business opportunities meeting the above-listed criteria to other entities. In addition, conflicts of interest may arise when our board evaluates a particular business opportunity with respect to the above-listed criteria. We cannot assure you that any of the above mentioned conflicts will be resolved in our favor.

On September 13, 2005, we issued 4,166,667 shares of our common stock to our initial stockholder, Healthcare Acquisition Partners Holdings, LLC, for an aggregate amount of $25,000 in cash, at a purchase price of approximately $0.006 per share. Healthcare Acquisition Parent, LLC currently holds a 100% interest in Healthcare Acquisition Partners Holdings, LLC. FTN Midwest Securities Corp. owns all the membership interests in Healthcare Acquisition Parent LLC. Prior to the completion of this offering, John Voris, our chief executive officer and a member of our Board, will receive a 14% interest in our initial stockholder Erin Enright, our chief financial officer, vice president and treasurer, will receive a 4% interest and each of Wayne Yetter and John-Pierre Millon, members of our Board, will receive an 8% interest. In addition, the 66% of the membership interests in our initial stockholder held by Healthcare Acquisition Parent, LLC may be allocated to current or future members of our management and/or to employees of FTN Midwest Securities Corp. or its affiliates. These interests may be subject to vesting requirements.

Healthcare Acquisition Parent, LLC, is the managing member of our initial stockholder. William Bischoff, a managing director of FTN Midwest Securities Corp., is the manager of Healthcare Acquisition Parent, LLC.

Prior to the completion of this offering, our initial stockholder, each member of our initial stockholder and each member of Healthcare Acquisition Parent, LLC, will enter into lock-up agreements restricting the sale of shares of our common stock, interests in our initial stockholder, and interests in Healthcare Acquisition Parent, LLC until six months after a business combination is completed. This agreement will not apply to the acquisition of securities by FTN Midwest Securities Corp. pursuant to the underwriting agreement (including the over-allotment option) and will allow FTN Midwest Securities Corp. to engage in stabilizing transactions and passive market-making as described in the section entitled “Underwriting.” In addition, each member of our initial stockholder and of Healthcare Acquisition Parent, LLC, will agree not to dissolve those entities prior to the earlier of the date that is six months after the completion of a business combination and the date of our liquidation.

Our initial stockholder will be entitled to make up to two demands that we register these shares pursuant to an agreement to be signed prior to or on the date of this prospectus. Our initial stockholder can elect to exercise these registration rights at any time subsequent to six months after the consummation of a business combination, pursuant to the terms of the lock-up agreement. In addition, our initial stockholder has certain “piggy-back” registration rights on registration statements filed subsequent to such date. We will bear the expenses incurred in connection with the filing of any such registration statements.

We will reimburse our officers and directors for any out-of-pocket business expenses incurred by them in connection with certain activities on our behalf such as identifying and investigating possible target businesses and business combinations. There is no limit on the amount of accountable out-of-pocket expenses reimbursable by us, which will be reviewed only by our board or a court of competent jurisdiction if such reimbursement is challenged; provided that no proceeds held in the trust account will be used to reimburse out-of-pocket expenses prior to a business combination.

Our chief executive officer, chief financial officer and each of our independent directors will receive an annual retainer of $50,000. John Voris, our chief executive officer and a director, will receive an additional $50,000 annual retainer for his services as a director.

All ongoing and future transactions between us and any of our officers and directors or their respective affiliates, including loans by our officers and directors, will be on terms we believe to be no less favorable than are available from unaffiliated third parties and such transactions or loans, including any forgiveness of loans, will require prior approval in each instance by a majority of our non-interested “independent” directors (to the extent we have any) or the members of our board who do not have an interest in the transaction, in either case who had access, at our expense, to our attorneys or independent legal counsel.

Our “parent” and “promoter,” as these terms are defined under the federal securities laws, are Healthcare Acquisition Partners Holdings, LLC and Healthcare Acquisition Parent, LLC.

The following table sets forth information regarding the beneficial ownership of our common stock prior to, and immediately upon completion of, this offering (assuming the following persons do not purchase units in this offering and there is no exercise of the underwriters’ over-allotment option), by:

Unless otherwise indicated, we believe that all persons named in the table have sole voting and investment power with respect to all shares of common stock beneficially owned by them.

The shares beneficially owned by Healthcare Acquisition Parent, LLC, John Voris, Wayne Yetter and Jean-Pierre Millon reflect what will be their respective percentage interests in Healthcare Acquisition Partners Holdings, LLC as of the date of the offering. Healthcare Acquisition Parent, LLC currently holds a 100% interest in Healthcare Acquisition Partners Holdings, LLC. In addition, as managing member of Healthcare Acquisition Partners Holdings, LLC, Healthcare Acquisition Parent, LLC. could be deemed to be the beneficial owner of all the shares held by Healthcare Acquisition Partners Holdings, LLC. As managing member of Healthcare Acquisition Parent, LLC, Mr. Bischoff could be deemed to be the beneficial owner of all the shares held by Healthcare Acquisition Partners Holdings, LLC. In addition, Mr. Bischoff is the control person of FTN Midwest Securities Corp.

manager of Healthcare Acquisition Parent, LLC. The common stock held by the initial stockholder will be subject to a lock-up agreement restricting its sale until six months after a business combination is completed. The membership interests in Healthcare Acquisition Partners Holdings, LLC and Healthcare Acquisition Parent, LLC will be subject to similar lock-up agreements. The members of each of Healthcare Acquisition Partners Holdings, LLC and Healthcare Acquisition Parent, LLC have agreed not to dissolve those entities prior to the earlier of the date that is six months after completion of a business combination and the date of our liquidation.

The 66% of the membership interests in our initial stockholder held by Healthcare Acquisition Parent, LLC may be allocated to current or future members of our management and/or to employees of FTN Midwest Securities Corp. or its affiliates. These interests may be subject to vesting requirements.

In addition, if we take advantage of increasing the size of the offering pursuant to Rule 462(b) under the Securities Act, we may effect a stock dividend in such amount to maintain the initial stockholder’s ownership at 20% of our issued and outstanding shares of common stock upon consummation of the offering.

Immediately after this offering, our initial stockholder will own 20.0% of the then issued and outstanding shares of our common stock. Because of this ownership block, our initial stockholder may be able to effectively exercise control over all matters requiring approval by our stockholders, including the election of directors and approval of significant corporate transactions, other than approval of the initial business combination.

All of the shares of our common stock outstanding prior to the consummation of this offering, all interests in Healthcare Acquisition Parent, LLC and all interests in our initial stockholder will be subject to a lock-up agreement between us, the initial stockholder, the members of our initial stockholder and the members of Healthcare Acquisition Parent, LLC restricting the sale of such shares until the earlier of six months following a business combination and our liquidation. During the lock-up period, the initial stockholder, its members and the members of Healthcare Acquisition Parent, LLC will not be able to sell or transfer the securities subject to the lock-up except to members of the initial stockholder, their spouses and children or trusts established for their benefit (who will be bound by the terms of the lock-up agreement). The initial stockholder will have all other rights as our stockholders, including without limitation, the right to vote its shares of common stock.

The initial stockholder does not have the right to participate in any liquidation distribution occurring upon our failure to consummate a business combination within the time period provided for in this prospectus with respect to those shares of common stock acquired by it prior to the consummation of this offering. Our initial stockholder, members of our management team and the beneficial owners of our initial stockholder and of Healthcare Acquisition Parent, LLC will agree not to purchase any additional shares of common stock, whether as part of this offering or otherwise, prior to the completion of a business combination. This agreement will not apply to the acquisition of securities by FTN Midwest Securities Corp. pursuant to the underwriting agreement (including the over-allotment option) and will allow FTN Midwest Securities Corp. to engage in stabilizing transactions and passive market-making as described in the section entitled “Underwriting.”

In addition, in connection with the vote required for our initial business combination, our initial stockholder has agreed to vote the shares of common stock owned by it immediately before the consummation of this offering, in the same way as the holders of the majority of the shares sold to the public in this offering and any other public offering.

We are authorized to issue 200,000,000 shares of common stock, par value $.0001 per share, and 1,000,000 shares of preferred stock, par value $.0001 per share. As of the date of this prospectus, 4,166,667 shares of common stock are outstanding, held by one recordholder and no shares of preferred stock are outstanding. Our initial stockholder will agree not to purchase any additional shares of common stock, whether as part of this offering or otherwise, prior to the completion of a business combination.

Each unit consists of one share of common stock and two warrants. Each warrant entitles its holder to purchase one share of common stock at an exercise price of $5.00. Each of the common stock and warrants will begin separate trading 20 days after the earlier of the expiration of the underwriters’ option to purchase up to 2,500,000 additional units to cover over-allotments and the exercise in full by the underwriters of such option; provided that we have filed with the SEC a Current Report on Form 8-K which includes an audited balance sheet. We intend to file a Current Report on Form 8-K which includes this audited balance sheet promptly after the consummation of this offering, which is anticipated to take place four business days after the date of this prospectus. The audited balance sheet will reflect the proceeds we receive from the exercise of the over-allotment option, if the over-allotment option is exercised contemporaneously with this offering. In addition, we intend to file a subsequent Current Report on Form 8-K in the event all or any portion of the over-allotment option is subsequently exercised.

Our stockholders are entitled to one vote for each share held of record on all matters to be voted on by stockholders. In connection with the vote required for our initial business combination, our initial stockholder has agreed to vote the shares of common stock owned by it immediately before the consummation of this offering in the same way as the holders of the majority of the shares sold to the public in this offering and any other public offering. Our initial stockholder will vote all of its shares in any manner it determines, in its sole discretion, with respect to any other matters that come before a vote of our stockholders.

We will proceed with the business combination only if a majority of the shares of common stock voted by the public stockholders are voted in favor of the business combination and public stockholders owning less than 20% of the shares sold in this offering exercise their conversion rights discussed below.

Our board of directors is not classified, and there is no cumulative voting with respect to the election of directors. As a result, the holders of more than 50% of the shares voted for the election of directors can elect all of the directors.

If we are forced to liquidate for failure to consummate a business combination within the time period provided in this prospectus, our public stockholders are entitled to a pro rata share of the trust account, inclusive of any interest, and any net assets remaining available for distribution to them after payment of liabilities. The initial stockholder does not have the right to participate in any liquidation distribution occurring upon our failure to consummate a business combination with respect to those shares of common stock acquired by it prior to the consummation of this offering.

Our stockholders have no conversion, preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to our common stock, except that public stockholders have the right to have their shares of common stock converted to cash equal to their pro rata share of the trust account if they vote against the initial business combination and the business combination is approved and completed. Public stockholders who convert their stock into their share of the trust account still have the right to exercise the warrants that they received as part of the units.

Our Amended and Restated Certificate of Incorporation authorizes the issuance of 1,000,000 shares of blank check preferred stock with such designation, rights and preferences as may be determined from time to time by our board of directors. No shares of preferred stock are being issued or registered in connection with this offering. Accordingly, our board of directors is empowered, without stockholder approval, to issue preferred stock with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of the holders of our common stock, although the underwriting agreement prohibits us, prior to a business combination, from issuing preferred stock which participates in any manner in the trust account, or which votes as a class with the common stock on the initial business combination. We may issue some or all of the preferred stock to effect a business combination. In addition, the preferred stock could be utilized as a method of discouraging, delaying or preventing a change in control of us. Although we do not currently intend to issue any shares of preferred stock, we cannot assure you that we will not do so in the future.

No warrants are currently outstanding. Each warrant offered hereby entitles its registered holder to purchase one share of our common stock at a price of $5.00 per share, subject to adjustment as discussed below, at any time commencing on the later of:

The warrants will expire five years from the date of this prospectus at 5:00 p.m., New York City time. We may call the warrants for redemption:

Our reason for permitting the redemption of the warrants under such circumstances is to enable us to simplify our capital structure once the warrants are “in the money,” by allowing us to require holders to exercise their warrants or have them redeemed. The price of $8.50 per share reflects a significant premium on the common stock price and using the 20 day threshold ensures that such a price level is more than a one-time event. We note that such redemption provisions are typical for other blank check companies similar to us that have registered the public offering of their securities.

The warrants will be issued in registered form under a warrant agreement between Mellon Investor Services LLC, as warrant agent, and us. You should review a copy of the warrant agreement, which has been filed as an exhibit to the registration statement of which this prospectus is a part, for a complete description of the terms and conditions applicable to the warrants.

The exercise price and number of shares of common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or our recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuances of common stock at a price below their respective exercise prices.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified check payable to us, for the number of warrants being exercised. The warrant holders do not have the rights or privileges of holders of

common stock or any voting rights until they exercise their warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

No warrants will be exercisable unless at the time of exercise a prospectus relating to common stock issuable upon exercise of the warrants is current and the common stock has been registered under the Securities Act of 1933 or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. Under the terms of the warrant agreement, we have agreed to meet these conditions and use our best efforts to maintain a current prospectus relating to common stock issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so. The warrants may be deprived of any value and the market for the warrants may be limited if the prospectus relating to the common stock issuable upon the exercise of the warrants is not current or if the common stock is not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside.

No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round up to the nearest whole number the number of shares of common stock to be issued to the warrant holder.

We have agreed to sell to FTN Midwest Securities Corp. an option to purchase up to a total of 958,333 units at a per-unit price of $7.50. The units issuable upon exercise of this option are identical to those offered by this prospectus except that the warrants included in the option have an exercise price of $6.25 (125% of the exercise price of the warrants included in the units sold in this offering). For a more complete description of the purchase option, see the section below entitled “Underwriting—Purchase Option.”

We have not paid any dividends on our common stock to date and do not intend to pay dividends prior to the completion of a business combination. The payment of dividends in the future will be contingent upon our revenues and earnings, if any, capital requirements and general financial condition subsequent to the completion of a business combination. The payment of any dividends subsequent to the consummation of a business combination will be within the discretion of our then board of directors. It is the present intention of our board of directors to retain all earnings, if any, for use in our business operations and, accordingly, our board of directors does not anticipate declaring any dividends in the foreseeable future.

The transfer agent for our securities and warrant agent for our warrants is Mellon Investor Services LLC.

Immediately after this offering, we will have 20,833,334 shares of common stock outstanding, or 23,333,334 shares if the underwriters’ over-allotment option is exercised in full. Of these shares, the 16,666,667 shares sold in this offering, or 19,166,667 shares if the over-allotment option is exercised, will be freely tradable without restriction or further registration under the Securities Act of 1933, except for any shares purchased by our affiliates within the meaning of Rule 144 under the Securities Act of 1933. All of the remaining 4,166,667 shares are restricted securities under Rule 144, in that they were issued in private transactions not involving a public offering. None of those shares will be eligible for re-sale under Rule 144 prior to September 13, 2006. Notwithstanding this, all of those shares are subject to lock-up agreements and will not be transferable until the earlier of six months following a business combination or our liquidation except in certain limited circumstances.

In general, under Rule 144 under the Securities Act of 1933, as amended, as currently in effect, a person who has beneficially owned restricted shares of our common stock for at least one year would be entitled to sell within any three-month period a number of shares that does not exceed the greater of either of the following:

Sales under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

Under Rule 144(k), a person who is not deemed to have been one of our affiliates at the time of or at any time during the three months preceding a sale, and who has beneficially owned the restricted shares proposed to be sold for at least two years, including the holding period of any prior owner other than an affiliate, is entitled to sell their shares without complying with the manner of sale, public information, volume limitation or notice provisions of Rule 144.

The SEC has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after a business combination, would act as an “underwriter” under the Securities Act of 1933 when reselling the securities of a blank check company. Accordingly, the SEC believes that those securities can be resold only through a registered offering and that Rule 144 would not be available for those resale transactions despite technical compliance with the requirements of Rule 144.

The holders of our 4,166,667 issued and outstanding shares of common stock immediately prior to the consummation of this offering will be entitled to registration rights with respect to those shares pursuant to an agreement to be signed prior to or on the effective date of this offering. Our initial stockholder is entitled to make up to two demands that we register these shares. Our initial stockholder can elect to exercise these registration rights any time subsequent to six months after the consummation of a business combination, pursuant to the terms of the lock-up agreement. In addition, our initial stockholder has certain “piggy-back” registration rights on registration statements filed subsequent to such date. We will bear the expenses incurred in connection with the filing of any such registration statements.

FTN Midwest Securities Corp. is also entitled to one demand for registration and “piggy-back” registration rights with respect to the securities subject to its purchase option.

We will issue our securities in the form of global securities registered in the name of Cede & Co., as nominee of DTC. Each global security will be issued only in fully registered form.

You may hold your beneficial interests in a global security directly through DTC if you have an account at DTC, or indirectly through organizations that have accounts at DTC.

A global security is a special type of indirectly held security in the form of a certificate held by a depositary for the investors in a particular issue of securities. Since we choose to issue our securities in the form of global securities, the ultimate beneficial owners can only be indirect holders. This is done by requiring that our global securities be registered in the name of a financial institution selected by us, as appropriate, and by requiring that

the securities underlying our global securities not be transferred to the name of any direct holder except in certain circumstances.

The financial institution that acts as the sole direct holder of a global security is called the “Depositary.” Any person wishing to own our securities must do so indirectly by virtue of an account with a broker, bank or other financial institution that in turn has an account with the Depositary. In the case of our securities, DTC will act as depositary and Cede & Co. will act as its nominee.

Except under limited circumstances or upon the issuance of securities in definitive form, a global security may be transferred, in whole and not in part, only to DTC, to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in a global security will be represented, and transfers of such beneficial interests will be made, through accounts of financial institutions acting on behalf of beneficial owners either directly as account holders, or indirectly through account holders, at DTC.

As an indirect holder, an investor’s rights relating to the global security will be governed by the account rules of the investor’s financial institution and of the Depositary, DTC, as well as general laws relating to securities transfers. We will not recognize this type of investor as a holder of our securities and instead will deal only with DTC, the Depositary that holds the global securities.

An investor in our securities should be aware that because these securities will be issued only in the form of global securities:

DTC is a limited purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act.

In accordance with the terms and conditions contained in the underwriting agreement, we have agreed to sell to each of the underwriters named below, and each of the underwriters, for which FTN Midwest Securities Corp. is acting as lead manager and sole book runner, have severally, and not jointly, agreed to purchase on a firm commitment basis the number of units offered in this offering set forth opposite their respective names below assuming no exercise of the underwriters’ over-allotment option:

The form of the underwriting agreement has been filed as an exhibit to the registration statement of which this prospectus forms a part.

Under the rules of the National Association of Securities Dealers, Inc. (“NASD”), FTN Midwest Securities Corp., which is participating in the offering as underwriter, may be deemed to be an affiliate of us and/or FTN Midwest Securities Corp. may be deemed to have a conflict of interest with us. Accordingly, the offering is being made in conformity with certain applicable provisions of NASD Rule 2720.

The lead manager has informed us that all the shares of our common stock in this offering will be offered and sold only to “qualified institutional buyers,” as defined in Rule 144A under the Securities Act and to institutions that qualify as “accredited investors” under Rule 501(a) under the Securities Act. In addition, you may purchase units in this offering only if you are an institutional investor as defined in the securities law of the state in which you reside, or in which you have your principal executive offices. The definition of “institutional investor” varies from state to state but generally includes banks and other financial institutions, broker-dealers, insurance companies, pension and profit-sharing plans, and other qualified entities. No sales may be made in any jurisdiction until any required action has been taken and completed and the registration statement relating to the units has been made effective by the SEC.

Your ability to resell the units and/or the common stock and warrants comprising the units may also be limited under state securities laws. You may initially be able to sell the securities only in those states where the securities are registered or where an applicable exemption from registration is available, including the exemption for transactions with institutional purchasers. Under the provisions of the National Securities Markets Improvement Act of 1996, or NSMIA, once we become a company that files annual and periodic reports under the Securities Exchange Act of 1934, securities registration requirements in all states are preempted for certain secondary market transactions. Some states, however, require a notice to be filed and a fee to be paid prior to making a sale in reliance upon this preemption. You should consult your financial and legal advisors to determine whether with respect to a specific state, an exemption from registration is available or the NSMIA preemption is applicable. In the case of both state exemptions and the NSMIA preemption, a state may attempt to prevent a secondary market sale of a security issued by a blank check company.

In the event that the warrants we are selling as part of a unit are resold to another person, the purchaser may not be able to exercise the warrants unless an exemption is available in the purchaser’s state of residence for the issuance of common stock upon exercise, or the shares have been registered in that state.

We have been advised by the lead manager and sole book runner that the underwriters propose to offer the units to the public at the initial offering price set forth on the cover page of this prospectus. They may allow some dealers concessions not in excess of $ per unit and the dealers may reallow a concession not in excess of $ per unit to other dealers.

Prior to this offering there has been no public market for any of our securities. The public offering price of the units and the terms of the warrants were negotiated between us and the representative. Factors considered in determining the prices and terms of the units, including the common stock and warrants underlying the units, include:

However, although these factors were considered, the determination of our offering price is more arbitrary than the pricing of securities for an operating company in a particular industry since the underwriters are unable to compare our financial results and prospects with those of public companies operating in the same industry.

We have granted to the underwriters an option, exercisable during the 45-day period commencing on the date of this prospectus, to purchase from us at the offering price, less underwriting discounts, up to an aggregate of 2,500,000 additional units for the sole purpose of covering over-allotments, if any. The over-allotment option will only be used to cover the net syndicate short position resulting from the initial distribution. The underwriters may exercise that option if the underwriters sell more units than the total number set forth in the table above. If any units underlying the option are purchased, the underwriters will severally purchase the units in approximately the same proportion as set forth in the table above.

The following table shows the public offering price, underwriting discount to be paid by us to the underwriters and the proceeds, before expenses, to us. This information assumes either no exercise or full exercise by the underwriters of their over-allotment option.

We have agreed to sell to FTN Midwest Securities Corp., for $100, an option to purchase up to a total of 958,333 units. The units issuable upon exercise of this option are identical to those offered by this prospectus except that the warrants included in the units have an exercise price of $6.25 (125% of the exercise price of the warrants included in the units sold in this offering). This option is exercisable at $7.50 per unit commencing on the later of the consummation of a business combination and one year from the date of this prospectus and expiring five years from the date of this prospectus. The purchase option and the 958,333 units, the 958,333 shares of common stock and the 1,916,666 warrants underlying such units, and the 1,916,666 shares of common stock underlying such warrants, have been deemed compensation by the NASD and are therefore subject to a 180-day lock-up pursuant to Rule 2710(g)(1) of the NASD Conduct Rules. The purchase option is subject to certain transfer restrictions.

The warrants and shares of our common stock that FTN Midwest Securities Corp. may obtain pursuant to this option will be subject to a lock-up agreement restricting their sale until six months after completion of a business combination. Shares obtained by FTN Midwest Securities Corp. pursuant to the underwriting agreement (including the over-allotment option), as part of stabilizing transactions or pursuant to market-making activities will not be subject to this lock-up.

Although the purchase option and its underlying securities have been registered under the registration statement of which this prospectus forms a part, the purchase option grants to holders demand and “piggy back” rights with respect to the registration under the Securities Act of 1933 of the securities directly and indirectly issuable upon exercise of the purchase option. We will bear all fees and expenses attendant to registering the securities underlying the purchase option, excluding only underwriting discounts and commissions which are to be paid by the holder of the securities to be sold. The exercise price and number of units issuable upon exercise of the purchase option may be adjusted in certain circumstances including in the event of a stock dividend, or our recapitalization, reorganization, merger or consolidation. However, the purchase option will not be adjusted for issuances of common stock at a price below its exercise price.

FTN Midwest Securities Corp. holds all of the membership interests in Healthcare Acquisition Parent, LLC, which in turn holds all of the membership interests in, and is the managing member of our initial stockholder. William Bishoff, a managing director of FTN Midwest Securities Corp., is the manager of Healthcare Acquisition Parent, LLC. Prior to the offering, membership interests representing 34% of our initial stockholder will be acquired by certain members of our management. In addition, the remaining 66% of the membership interests in our initial stockholder held by Healthcare Acquisition Parent, LLC may be allocated to current or future members of our management and/or to employees of FTN Midwest Securities Corp. or its affiliates. These interests may be subject to vesting requirements. See “Principal Stockholders”.

FTN Midwest Securities Corp. holds all of the membership interests in our initial shareholder and is also the lead manager and sole bookrunner in this offering and, thereby, is an affiliate of Healthcare Acquisition Partners Corp. Each initial offering of securities will be conducted in compliance with the requirements of Rule 2720 of the National Association of Securities Dealers, Inc., which is commonly referred to as the NASD, regarding a NASD member firm’s distributing the securities of an affiliate. Following the initial distribution of any of these securities, FTN Midwest Securities Corp. or any of its affiliates may offer and sell these securities in the course of their business as broker dealers. FTN Midwest Securities Corp. and its affiliates may act as principals or agents in these transactions and may make any sales at varying prices related to prevailing market prices at the time of sale or otherwise. FTN Midwest Securities Corp. and its affiliates may use this prospectus in connection with these transactions. Neither FTN Midwest Securities Corp. nor any of its affiliates is obligated to make a market in any of these securities and may discontinue any market making activities at any time without notice.

Rules of the SEC may limit the ability of the underwriters to bid for or purchase our units before the distribution of the units is completed. However, the underwriters may engage in the following activities in accordance with the rules:

Stabilization and syndicate covering transactions may cause the price of the units to be higher than it would be in the absence of these transactions. The imposition of a penalty bid might also have an effect on the price of the securities if it discourages resales of the securities.

Neither we nor the underwriters makes any representation or prediction as to the effect that the transactions described above may have on the price of the securities. These transactions may occur on the OTC Bulletin Board, in the over-the-counter market or on any trading market. If any of these transactions are commenced, they may be discontinued without notice at any time.

We have entered into agreements with FTN Midwest Securities Corp. and certain officers and directors, under the terms of which each of them has agreed to present to us for our consideration any opportunity to acquire all or substantially all of the outstanding equity securities of, or otherwise acquire a controlling equity interest in, an operating business in the healthcare, or a healthcare-related, sector, provided that they are under no obligation to present to us any opportunity involving a business in the healthcare, or a healthcare-related, sector seeking a strategic combination with another operating business in the healthcare, or a healthcare-related, sector. The terms of these agreements do not obligate these individuals or FTN Midwest Securities Corp. to present any opportunities to us for consideration prior to presenting such opportunities to any other person or entity.

Although neither the underwriters nor their representatives are obligated to do so, any of them may introduce us to potential target businesses or assist us in raising additional capital, as needs may arise in the future, but there are no preliminary agreements or understandings between any of the underwriters and any potential targets. We are not under any contractual obligation to engage any of the underwriters to provide any services for us after this offering, but if we do, we may pay the underwriters a finder’s fee that would be determined at that time in an arm’s length negotiation subject to the approval of the independent directors where the terms would be fair and reasonable to each of the interested parties; provided that no agreement will be entered into and no fee will be paid prior to the one year anniversary of the date of this prospectus.

We have agreed to indemnify the underwriters against some liabilities, including civil liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make in this respect.

The validity of the securities offered in this prospectus are being passed upon for us by Morgan, Lewis & Bockius LLP, New York, New York. Certain legal matters with respect to this offering will be passed upon for the underwriters by Sidley Austin Brown & Wood LLP, New York, New York.

The financial statements of Healthcare Acquisition Partners Corp. at September 15, 2005 and for the period from August 15, 2005 (date of inception) through September 15, 2005 appearing in this prospectus and in the registration statement have been included herein in reliance upon the report of Miller, Ellin & Company LLP, independent registered public accounting firm, given on the authority of such firm as experts in accounting and auditing.

We have filed with the SEC a registration statement on Form S-1, which includes exhibits, schedules and amendments, under the Securities Act of 1933, with respect to this offering of our securities. Although this prospectus, which forms a part of the registration statement, contains all material information included in the registration statement, parts of the registration statement have been omitted as permitted by rules and regulations of the SEC. We refer you to the registration statement and its exhibits for further information about us, our securities and this offering. The registration statement and its exhibits, as well as our other reports filed with the SEC, can be inspected and copied at the SEC’s public reference room at 100 F Street, N.E., Washington, D.C. 20549. The public may obtain information about the operation of the public reference room by calling the SEC at 1-800-SEC-0330. In addition, the SEC maintains a web site at http://www.sec.gov which contains the Form S–1 and other reports, proxy and information statements and information regarding issuers that file electronically with the SEC.

We have audited the accompanying balance sheet of Healthcare Acquisition Partners Corp. (a corporation in the development stage) as of September 15, 2005, and the related statement of operations, stockholders’ equity, and cash flows for the period from August 15, 2005 (date of inception) through September 15, 2005. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Healthcare Acquisition Partners Corp. as of September 15, 2005, and the results of its operations and its cash flows for the period from August 15, 2005 (date of inception) to September 15, 2005, in conformity with United States generally accepted accounting principles.

/s/ MILLER, ELLIN & COMPANY, LLP

CERTIFIED PUBLIC ACCOUNTANTS

Healthcare Acquisition Partners Corp. (the “Company”) was incorporated in Delaware on August 15, 2005 as a blank check company whose objective is to acquire through a merger, capital stock exchange, asset acquisition or other similar business combination, one or more operating businesses primarily in the healthcare sector.

At September 15, 2005, the Company had not yet commenced any operations. All activity through September 15, 2005 relates to the Company’s formation and the proposed public offering described below. The Company has selected December 31 as its fiscal year end.

The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a proposed public offering (“Proposed Offering”) which is discussed in Note 2. The Company’s management has broad discretion with respect to the specific application of the net proceeds of this Proposed Offering, although substantially all of the net proceeds of this Proposed Offering are intended to be generally applied toward consummating a Business Combination with one or more operating businesses whose fair market value is, either individually or collectively, at least 80% of the Company’s net assets at the time of such acquisition (“Business Combination”). Furthermore, there is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Proposed Offering, at least ninety percent (90%) of the net proceeds, after payment of certain amounts to the underwriter, will be held in a trust account (“Trust Account”) and invested in U.S. government securities until the earlier of (i) the consummation of a Business Combination and (ii) liquidation of the Company. The remaining net proceeds (not held in the Trust Account) may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses. The Company, after signing a definitive agreement for the acquisition of a target business, will submit such transaction for stockholder approval. In the event that stockholders owning 19.99% or more of the shares sold in the Proposed Offering vote against the Business Combination and exercise their conversion rights described below, the Business Combination will not be consummated. The Company’s stockholder prior to the Proposed Offering, (the “Initial Stockholder”), has agreed to vote its 4,166,667 founding shares of common stock in accordance with the vote of the majority in interest of all other stockholders of the Company (“Public Stockholders”) with respect to any Business Combination. The Initial Stockholder has agreed not to acquire any additional shares of the registrant in connection with or following the Proposed Offering. After consummation of a Business Combination, these voting safeguards will no longer be applicable.

The Company’s Amended and Restated Certificate of Incorporation provides for mandatory liquidation of the Company in the event that the Company does not consummate a Business Combination within 18 months from the date of the consummation of the Proposed Offering, or 24 months from the consummation of the Proposed Offering if certain extension criteria have been satisfied. In the event of liquidation, it is likely that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be less than the initial public offering price per share in the Proposed Offering (assuming no value is attributed to the Warrants contained in the Units to be offered in the Proposed Offering discussed in Note 2).

Loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period.

The Company uses the liability method for reporting income taxes, under which current and deferred tax liabilities and assets are recorded in accordance with enacted tax laws and rates. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Under the liability method, the amounts of deferred tax liabilities and assets at the end of each period are determined using the tax rate expected to be in effect when taxes are actually paid or recovered. Future tax benefits are recognized when it is more likely than not that such benefits will be realized.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Management does not believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

The Proposed Offering calls for the Company to offer for public sale up to 16,666,667 units (“Units”). Each Unit consists of one share of the Company’s common stock, $.0001 par value, and two Redeemable Common Stock Purchase Warrants (“Warrants”). Each Warrant will entitle the holder to purchase from the Company one share of common stock at an exercise price of $5.00 commencing the later of the completion of a Business Combination or one year from the effective date of the Proposed Offering and expiring five years from the effective date of the Proposed Offering. The Company may call the Warrants for redemption in whole and not in part at a price of $.01 per Warrant at any time after the Warrants become exercisable. They cannot be redeemed unless the Warrant holders receive written notice not less than 30 days prior to the redemption; and if, and only if, the reported last sale price of the common stock equals or exceeds $8.50 per share for any 20 trading days within a 30 trading day period ending on the third business day prior to the notice of redemption to Warrant holders.

In addition, the Company will issue (See Note 4) to FTN Midwest Securities Corp., for $100, an option to purchase up to a total of 958,333 units. The units issuable upon exercise of this option are identical to those offered in this Proposed Offering, except that each of the warrants underlying this option entitles the holder to purchase one share of our common stock at a price of $6.25. This option is exercisable at $7.50 per unit commencing on the later of the consummation of a Business Combination and one year from the date of the prospectus and expiring five years from the date of the prospectus. The option may only be exercised or converted by the option holder.

The sale of the option will be accounted for as an equity transaction. Accordingly, there will be no net impact on the Company’s financial position or results of operations, except for the recording of the $100 proceeds from the sale. The Company has preliminarily estimated that the fair value of the above option on the date of sale would be approximately $2.36 per unit, or $2,261,666 total, using an expected life of five years, volatility of 47% and a risk-free interest rate of 3.98%.

The volatility calculation of 47% is based on the 180 day average volatility of a representative sample of forty-one (41) companies with market capitalization under $200 million that Management believes could be considered to be engaged in a business in the Healthcare Industry (the “Sample Companies”). Because the Company does not have a trading history, the Company needed to estimate the potential volatility of its

common stock price, which will depend on a number of factors, which cannot be ascertained at this time. The Company referred to the 180 day average volatility of the Sample Companies because Management believes that the average volatility of such companies is a reasonable benchmark to use in estimating the expected volatility of the Company’s common stock post-business combination. Although an expected life of five years was taken into account for purposes of assigning a fair value to the option, if the Company does not consummate a business combination within the prescribed time period and liquidates, the option would become worthless.

The Company has a commitment to pay an underwriting discount of 7% of the public offering price and a non-accountable expense allowance of 1% of the public offering price to FTN Midwest Securities Corp., representative of the underwriters, at the closing of the Proposed Offering. The Company may pay financial advisory fees in connection with a Business Combination.

The Company will also issue an option to the underwriters to purchase up to a total of 958,333 units at a price of $7.50. The units issuable upon the exercise of this option are identical to those offered in the prospectus, except that the exercise price of the warrants underlying the underwriters’ purchase option is $6.25.

After completion of the Proposed Offering, the Company’s independent directors will receive annual compensation of $50,000.

The Company has entered into agreements with FTN Midwest Securities Corp. and certain officers and directors whereby each of them has agreed to present to the Company for the Company’s consideration any opportunity to acquire all or substantially all of the outstanding equity securities of, or otherwise acquire a controlling equity interest in, an operating business in the healthcare, or a healthcare-related, sector, provided that they are under no obligation to present to the Company any opportunity involving a business in the healthcare, or a healthcare-related, sector seeking a strategic combination with another operating business in the healthcare, or a healthcare-related, sector.

The Company is authorized to issue 1,000,000 shares of preferred stock with such designations, voting and other rights and preferences as may be determined from time to time by the Board of Directors.

The Company will utilize certain administrative, technology and secretarial services, as well as certain limited office space provided by FTN Midwest Securities Corp. until the consummation of a Business Combination by the Company. The Company has agreed to pay $7,500 per month for such services commencing on the effective date of the Proposed Offering and continuing monthly thereafter.

On October 4, 2005, the Company borrowed $60,000 of unsecured promissory notes from the Initial Stockholder. The notes bear interest at a rate of 3% per annum and are payable on the earlier of September 28, 2006 or the date the Company consummates the Proposed Offering. Due to the short-term nature of the notes, the fair value of the notes approximates their carrying amount. There were no amounts outstanding as of September 15, 2005.

The estimated expenses payable by us in connection with the offering described in this registration statement (other than the underwriting discount and commissions and the representative non-accountable expense allowance) will be as follows:

Our Amended and Restated Certificate of Incorporation provides that all directors, officers, employees and agents of the registrant shall be entitled to be indemnified by us to the fullest extent permitted by Section 145 of the Delaware General Corporation Law. Section 145 of the Delaware General Corporation Law concerning indemnification of officers, directors, employees and agents is set forth below.

“Section 145. Indemnification of officers, directors, employees and agents; insurance.

(a) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person’s conduct was unlawful.

(b) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of

such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

(c) To the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith.

(d) Any indemnification under subsections (a) and (b) of this section (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. Such determination shall be made, with respect to a person who is a director or officer at the time of such determination, (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (2) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (4) by the stockholders.

(e) Expenses (including attorneys’ fees) incurred by an officer or director in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this section. Such expenses (including attorneys’ fees) incurred by former directors and officers or other employees and agents may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

(f) The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office.

(g) A corporation shall have power to purchase and maintain insurance on behalf of any person who is or was director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under this section.

(h) For purposes of this section, references to “the corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued.

(i) For purposes of this section, references to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to “serving at the request of the corporation” shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the corporation” as referred to in this section.

(j) The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

(k) The Court of Chancery is hereby vested with exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this section or under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. The Court of Chancery may summarily determine a corporation’s obligation to advance expenses (including attorneys’ fees).”

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to our directors, officers, and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment of expenses incurred or paid by a director, officer or controlling person in a successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to the court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Article Seventh, paragraph B of our Amended and Restated Certificate of Incorporation provides:

“The Corporation, to the full extent permitted by Section 145 of the DGCL, as amended from time to time, shall indemnify all persons whom it may indemnify pursuant thereto. Expenses (including attorneys’ fees) incurred by an officer or director in defending any civil, criminal, administrative, or investigative action, suit or proceeding or which such officer or director may be entitled to indemnification hereunder shall be paid by the Corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized hereby.”

Article VII of our Bylaws provides for indemnification of any of our present or former directors, officers, employees or agents for certain matters in accordance with Section 145 of the DGCL.

Pursuant to the Underwriting Agreement filed as Exhibit 1.1 to this Registration Statement, we have agreed to indemnify the Underwriters and the Underwriters have agreed to indemnify us against certain civil liabilities that may be incurred in connection with this offering, including certain liabilities under the Securities Act of 1933.

(a) During the past three years, we sold the following shares of common stock without registration under the Securities Act:

Such shares were issued on September 13, 2005 in connection with our organization pursuant to the exemption from registration contained in Section 4(2) of the Securities Act of 1933. The shares issued to Healthcare Acquisition Partners Holdings, LLC for an aggregate offering price of $25,000, or at an average purchase price of approximately $0.006 per share. No underwriting discounts or commissions were paid with respect to such sales.

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

i. To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

ii. To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

iii. To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned hereby undertakes to provide to the underwriter at the closing specified in the underwriting agreements, certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Pursuant to the requirements of the Securities Act of 1933, the Registrant has duly caused this amendment no. 1 to registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in New York, New York, on December 8, 2005.

	Terms of This Offering	Terms Under a Rule 419 Offering
Escrow of offering proceeds	$89,595,000 of the net offering proceeds will be deposited into a trust account located at and maintained by JPMorgan Chase Bank, N.A.	$82,800,000 of the offering proceeds would be required to be deposited into either an escrow account with an insured depositary institution or in a separate bank account established by a broker-dealer in which the broker-dealer acts as trustee for persons having the beneficial interests in the account.

Investment of net proceeds	The $89,595,000 of net offering proceeds held in trust will be invested in a money market fund, selected by us, which invests principally in short-term securities issued or guaranteed by the United States having a rating in the highest investment category granted thereby by a recognized credit rating agency at the time of acquisition.	Proceeds could be invested only in specified securities such as a money market fund meeting conditions of the Investment Company Act of 1940 or in securities that are direct obligations of, or obligations guaranteed as to principal or interest by, the United States.

Limitation on fair value or net assets of target business	The initial target businesses that we acquire must have a fair market value equal to at least 80% of our net assets at the time of such acquisition.	We would be restricted from acquiring a target business unless the fair value of such business or net assets to be acquired represent at least 80% of the maximum offering proceeds.


	Terms of This Offering	Terms Under a Rule 419 Offering

Trading of securities issued	The units may commence trading on or promptly after the date of this prospectus. The common stock and warrants comprising the units will begin to trade separately 20 days after the earlier of the expiration of the underwriters’ option to purchase up to 2,500,000 additional units to cover over-allotments, and the exercise in full by the underwriters of such option, provided that we have filed with the SEC a Current Report on Form 8-K, which includes an audited balance sheet reflecting our receipt of the net proceeds of this offering, including any proceeds we receive from the exercise of the over-allotment option, if such option is exercised prior to the filing of the Form 8-K. In addition, we will file a subsequent Current Report on Form 8-K in the event a material portion of the over-allotment option is exercised subsequent to the filing of our initial Current Report on Form 8-K.	No trading of the units or the underlying common stock and warrants would be permitted until the completion of a business combination. During this period, the securities would be held in the escrow or trust account.

Exercise of the warrants	The warrants cannot be exercised until the later of the completion of a business combination or one year from the date of this prospectus and, accordingly, will only be exercised after the trust account has been terminated and distributed.	The warrants could be exercised prior to the completion of a business combination, but securities received and cash paid in connection with the exercise would be deposited in the escrow or trust account.


	Terms of This Offering	Terms Under a Rule 419 Offering

Election to remain an investor	We will give our stockholders the opportunity to vote on the business combination. In connection with seeking stockholder approval, we will send each stockholder a proxy statement containing information required by the SEC. A stockholder who votes against the business combination following the procedures described in this prospectus is given the right to convert his or her shares into his or her pro rata share of the trust account. However, a stockholder who votes against the business combination but who does not follow these procedures or a stockholder who does not vote against the business combination would not be entitled to the conversion right.	A prospectus containing information required by the SEC would be sent to each investor. Each investor would be given the opportunity to notify the company, in writing, within a period of no less than 20 business days and no more than 45 business days from the effective date of the post-effective amendment, to notify the company of his or her election to remain an investor. If the company has not received the notification by the end of the 45th business day, funds and interest or dividends, if any, held in the trust or escrow account would automatically be returned to the stockholder. Unless a sufficient number of investors elect to remain investors, all of the deposited funds in the escrow account must be returned to all investors and none of the securities would be issued.

Business combination deadline	A business combination must occur within 18 months after the consummation of this offering or within 24 months after the consummation of this offering if a definitive agreement relating to a prospective business combination was entered into prior to the end of the 18-month period after the consummation of this offering.	If an acquisition has not been consummated within 18 months after the effective date of the initial registration statement, funds held in the trust or escrow account would be returned to investors.

Release of funds	The proceeds held in the trust account will not be released until the earlier of the completion of a business combination or our liquidation upon our failure to effect a business combination within the allotted time period provided in this prospectus.	The proceeds held in the escrow account would not be released until the earlier of the completion of a business combination or the failure to effect a business combination within the allotted time.
