Form of Underwriting Agreement

Healthcare Acquisition Partners Corp., a Delaware corporation (the “Company”), confirms its agreement with FTN Midwest Securities Corp. (“FTN”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters”), for whom FTN is acting as representative (in such capacity, the “Representative”), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of units of the Company (the “Units”, and the Units to be purchased by the Underwriters pursuant hereto are referred to as the “Initial Units”) set forth in said Schedule A, and with respect to the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 2,500,000 additional Units (the “Option Units”) to cover overallotments, if any. Each Unit consists of one share of the Company’s common stock, par value $.0001 per share (the “Common Stock”), and two warrants (each, a “Warrant”). Each Warrant entitles its holder to exercise it to purchase one share of Common Stock for an exercise price of $5.00 during the period commencing on the later of the consummation by the Company of its “Business Combination” or one year from the effective date (the “Effective Date”) of the Registration Statement (as defined below) and terminating on the fifth anniversary of the Effective Date. “Business Combination” means any merger, capital stock exchange, asset acquisition or other similar business combination consummated by the Company with an operating business, as described in the Registration Statement. The Units, the shares of Common Stock and the Warrants included in the Units, and the shares of Common Stock issuable upon exercise of the Warrants are hereinafter collectively referred to as the “Public Securities”. The Public Securities and the Representative’s Securities (as defined in Section 2(c) hereof) are hereinafter collectively referred to as the “Securities”.

The Company has entered into a warrant agreement with respect to the Warrants and the Representative’s Warrants (as defined in Section 2(c)) with Mellon Investor Services LLC on l, 2005 (the “Warrant Agreement”). The Company has caused its initial stockholder who owns shares of Common Stock immediately prior to the consummation of the offering pursuant to this Agreement (the “Initial Stockholder”) to enter into an escrow agreement (the “Escrow Agreement”) with JPMorgan Chase Bank, N.A. (the “Escrow Agreement”) on l, 2005, pursuant to which the shares of Common Stock owned by the Initial Stockholder immediately prior to the consummation of the offering pursuant to this Agreement will be held in escrow by the Escrow Agent until the third anniversary of the Effective Date. The company has entered into a service agreement (the “Service Agreement”) with [FTN] (in such capacity, the “Servicer”), pursuant to which the Servicer will

make available to the Company general and administrative services including office space, utilities and secretarial support for the Company’s use for $7,500 per month. The Company has entered into an Investment Management Trust Agreement (the “Trust Agreement”) with l, on l, 2005, pursuant to which $89,595,000 of the proceeds received by the Company for the Initial Units will be deposited in a trust fund (the “Trust Fund”) for the benefit of holders of any of the Units, shares of Common Stock or Warrants offered to the public pursuant to this Agreement.

The Company understands that the Underwriters propose to make a public offering of the Public Securities as soon as the Representative deems advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (No. 333-129035), including the related preliminary prospectus or prospectuses, covering the registration of the Securities under the Securities Act of 1933, as amended (the “1933 Act”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430A (“Rule 430A”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”) and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations. The information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective pursuant to paragraph (b) of Rule 430A is referred to as “Rule 430A Information.” Each prospectus used before such registration statement became effective, and any prospectus that omitted the Rule 430A Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a “preliminary prospectus.” Such registration statement, including the exhibits and any schedules thereto, at the time it became effective, and including the Rule 430A Information, is herein called the “Registration Statement.” Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the “Rule 462(b) Registration Statement,” and after such filing the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The final prospectus in the form first furnished to the Underwriters for use in connection with the offering of the Securities is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

(a) Representations and Warranties by the Company.

(xii) Absence of Defaults and Conflicts. The Company is not in violation of its charter or by-laws or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company is subject (collectively, “Agreements and Instruments”); and the execution, delivery and performance of this Agreement, the Warrant Agreement, the Representative’s Purchase Option, the Trust Agreement, the Services Agreement and the Escrow Agreement and the consummation of the transactions contemplated herein, therein and in the Registration Statement (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations hereunder and thereunder have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to, the Agreements and Instruments, nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its assets, properties or operations.

(xviii) Title to Property. The Company has good and marketable title to all real property owned by the Company and good title to all other properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind except such as (a) are described in the Prospectus or (b) do not, singly or in the aggregate, materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company; and all of the leases and subleases material to the business of the Company, and under which the Company holds properties described in the Prospectus, are in full force and effect, and the Company has not any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company to the continued possession of the leased or subleased premises under any such lease or sublease.

(the “NASD”).

(b) Officer’s Certificates. Any certificate signed by any officer of the Company delivered to the Representative or to counsel for the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby.

(a) Initial Units. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the price per Unit set forth in Schedule B, the number of Initial Units set forth in Schedule A opposite the name of such Underwriter.

(b) Option Units. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option

to the Underwriters, severally and not jointly, to purchase up to an additional 2,500,000 Units at the price per unit set forth in Schedule B, less an amount per unit equal to any dividends or distributions declared by the Company and payable on the Initial Units but not payable on the Option Units. The option hereby granted will expire 45 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering overallotments which may be made in connection with the offering and distribution of the Initial Units upon notice by the Representative to the Company setting forth the number of Option Units as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Units. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representative, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Units, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Units then being purchased which the number of Initial Units set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Units, subject in each case to such adjustments as FTN in its discretion shall make to eliminate any sales or purchases of fractional shares.

(c) Purchase Option. The Company hereby agrees to issue and sell to the Representative (and/or its designees) on the Effective Date an option (the “Representative’s Purchase Option”) for the purchase of an aggregate of 958,333 Units (the “Representative’s Units”) for an aggregate purchase price of $7,187,497.50. Each of the Representative’s Units is identical to the Initial Units except that the Warrants included in the Representative’s Units (the “Representative’s Warrants”) have an exercise price of $6.25 (125% of the exercise price of the Warrants included in the Units sold to the public). The Representative’s Purchase Option shall be exercisable, in whole or in part, commencing on the later of (i) one year from the Effective Date and (ii) the consummation of a Business Combination and expiring on the five-year anniversary of the Effective Date at an initial exercise price per Representative’s Unit of $7.50, which is equal to 125% of the initial public offering price of a Unit. The Representative’s Purchase Option, the Representative’s Units, the Representative’s Warrants and the shares of Common Stock issuable upon exercise of the Representative’s Warrants are hereinafter referred to collectively as the “Representative’s Securities.”

(d) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Units shall be made at the offices of Sidley Austin Brown & Wood LLP at 787 Seventh Avenue, New York, NY 10019, or at such other place as shall be agreed upon by the Representative and the Company, at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof, or such other time not later than ten business days after such date as shall be agreed upon by the Representative and the Company (such time and date of payment and delivery being herein called “Closing Time”).

In addition, in the event that any or all of the Option Units are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Units shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company, on each Date of Delivery as specified in the notice from the Representative to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Representative for the respective accounts of the Underwriters of certificates for the Units to be purchased by them. It is understood that each Underwriter has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Units and the Option Units, if any, which it has agreed to purchase. FTN, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Units or the Option Units, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant

Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(e) Denominations; Registration. Certificates for the Securities shall be in such denominations and registered in such names as the Representative may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates for the Securities will be made available for examination and packaging by the Representative in The City of New York not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

The Company will promptly effect the filings necessary pursuant to Rule 424(b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Company will give the Representative notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)) or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus will furnish the Representative with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representative or counsel for the Underwriters shall object.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Public Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representative may designate and to maintain such qualifications in effect for a period of not less than one year from the later of the effective date of the Registration Statement and any Rule 462(b) Registration Statement; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(g) Rule 158.

The Company will not consummate a Business Combination with any entity which is affiliated with FTN or any Initial Stockholder or with respect to which FTN or any of its affiliates submitted a proposal or provided other merger and acquisition services unless (i) such Business Combination has been approved by a majority of the Company’s independent directors [and (ii) the Company obtains an opinion from an independent investment banking firm that such Business Combination is fair to the Company’s stockholders from a financial perspective]. Except as set forth in the Service Agreement, the Company shall not pay FTN or any Initial Stockholder or any of their affiliates any fees or compensation, for services rendered to the Company prior to, or in connection with, the consummation of a Business Combination; provided that FTN and the Initial Stockholder shall be entitled to reimbursement from the Company for their reasonable out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination.

(l) Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the rules and regulations of the Commission thereunder.

(m) Reports to the Representative. For a period of five years from the Effective Date, the Company will furnish to the Representative and its counsel copies of such financial statements and other periodic and special reports as the Company from time to time furnishes generally to holders of any class of its securities, and promptly furnish to the Representative (i) a copy of each periodic report the Company shall be required to file with the Commission, (ii) a copy of every press release and every news item and article with respect to the Company or its affairs which was released by the Company,(iii) a copy of each Form 8-K or Schedules 13D, 13G, 14D-1 or 13E-4 received or prepared by the Company, (iv) five copies of each registration statement filed by the Company with the Commission under the 1933 Act, (v) a copy of monthly statements, if any, setting forth such information regarding the Company’s results of operations and financial position (including balance sheet, profit and loss statements and data regarding outstanding purchase orders) as is regularly prepared by management of the Company and (vi) such additional documents and information with respect to the Company and the affairs of any future subsidiaries of the Company as the Representative may from time to time reasonably request.

(n) Notice to NASD. In the event any person or entity (regardless of any NASD affiliation or association) is engaged to assist the Company in its search for a merger candidate or to provide any other merger and acquisition services, the Company will provide the following to the NASD and FTN prior to the consummation of the Business Combination: (i) complete details of all services and copies of agreements governing such services; and (ii) justification as to why the person or entity providing the merger and acquisition services should not be considered an “underwriter and related person” with respect to the Company’s initial public offering, as such term is defined in Rule 2710 of the NASD’s Conduct Rules. The Company also agrees that proper disclosure of such arrangement or potential arrangement will be made in the proxy statement which the Company will file for purposes of soliciting stockholder approval for the Business Combination. Further, the Company agrees to promptly advise the NASD and the Representative and its counsel if it learns that any officer, director or owner of at least 5% of the Company’s outstanding shares of Common Stock becomes an affiliate or associated person of an NASD member participating in the distribution of the Public Securities.

The Company will establish and maintain a system of internal accounting controls sufficient to provide reasonable assurances that: (i) transactions are executed in accordance with management’s general or specific authorization, (ii) transactions are recorded as necessary in order to permit preparation of financial statements in accordance with generally accepts accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(p) Accountants. Until the earlier of five years from the Effective Date or until such earlier time upon which the Company is required to be liquidated, the Company shall retain an independent public accountant.

(q) Form 8-K. The Company shall, on the date hereof, retain its independent public accountants to audit the financial statements of the Company as of the Closing Time (the “Audited Financial Statements”) reflecting the receipt by the Company of the proceeds of the initial public offering. As soon as the Audited Financial Statements become available, the Company shall immediately file a Current Report on Form 8-K with the Commission, which Report shall contain the Audited Financial Statements.

(r) Business Combination Announcement. Within five business days following the consummation by the Company of a Business Combination, the Company shall cause an announcement (the “Business Combination Announcement”) to be placed, at its cost, in THE WALL STREET JOURNAL, THE NEW YORK TIMES and a third publication to be selected by the Representative announcing the consummation of the Business Combination and indicating that the Representative was the managing underwriter in the offering. The Company shall supply the Representative with a draft of the Business Combination Announcement and provide the Representative with a reasonable opportunity to comment thereon. The Company will not place the Business Combination Announcement without the final approval of the Representative, which approval will not be unreasonably withheld.

(s) Trust Fund Waiver Acknowledgment. The Company hereby agrees that it will not commence its due diligence investigation of any operating business which the Company seeks to acquire (the “Target Business”) or obtain the services of any vendor unless and until such Target Business or vendor acknowledges in writing, whether through a letter of intent, memorandum of understanding or other similar document (and subsequently acknowledges the same in any definitive document replacing any of the foregoing), that (a) it has read the Prospectus and understands that the Company has established the Trust Fund, initially in an amount of $89,595,000 for the benefit of the public stockholders and that the Company may disburse monies from the Trust Fund only (i) to the public stockholders in the event they elect to convert their IPO Shares (as defined in Section 3(w)) and the liquidation of the Company or (ii) to the Company after it consummates a Business Combination and (b) for and in consideration of the Company (i) agreeing to evaluate such Target Business for purposes of consummating a Business Combination with it or (ii) agreeing to engage the services of the vendor, as the case may be, such Target Business or vendor agrees that it does not have any right, title, interest or claim of any kind in or to any monies in the Trust Fund (the “Claims”) and waives any Claim it may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company and will not seek recourse against the Trust Fund for any reason whatsoever.

(t) Insider Letters. The Company shall not take any action or omit to take any action which would cause a breach of any of the Insider Letters executed between each Initial Stockholder and FTN and will not allow any amendments to, or waivers of, such Insider Letters without the prior written consent of the Representative.

(u) Certificate of Incorporation and Bylaws. The Company shall not take any action or omit to take any action that would cause the Company to be in breach or violation of its Certificate of Incorporation or Bylaws. Prior to the consummation of a Business Combination, the Company will not amend its Certificate of Incorporation without the prior written consent of the Representative.

(v) Blue Sky Requirements. The Company shall provide counsel to the Representative with ten copies of all proxy information and all related material filed with the Commission in connection with a Business Combination concurrently with such filing with the Commission. In addition, the Company shall furnish any other state in which its initial public offering was registered such information as may be requested by such state.

(w) Acquisition/Liquidation Procedure. The Company agrees: (i) that, prior to the consummation of any Business Combination, it will submit such transaction to the Company’s stockholders for their approval (the “Business Combination Vote”) even if the nature of the acquisition is such as would not ordinarily require stockholder approval under applicable state law; and (ii) that, in the event that the Company does not effect a Business Combination within 18 months from the consummation of this offering (subject to extension for an additional six-month period, as described in the Prospectus), the Company will be liquidated and will distribute to all holders of IPO Shares (as defined below) an aggregate sum equal to the Company’s “Liquidation Value”. The Company’s “Liquidation Value” means the Company’s book value, as determined by the Company and approved by its independent accountant. In no event, however, will the Company’s Liquidation Value be less than the Trust Fund, inclusive of any net interest income thereon. Only holders of IPO Shares shall be entitled to receive liquidating distributions with respect to the IPO Shares they beneficially own and the Company shall pay no liquidating distributions with respect to any other shares of capital stock of the Company. With respect to the Business Combination Vote, the Company shall cause the Initial Stockholder to vote the shares of Common Stock owned by it immediately prior to the consummation of the offering in accordance with the vote of the holders of a majority of the IPO Shares present, in person or by proxy, at a meeting of the Company’s stockholders called for such purpose. At the time the Company seeks approval of any potential Business Combination, the Company will offer each holder of the Company’s Common Stock issued in this offering (the “IPO Shares”) the right to convert their IPO Shares at a per share price (the “Conversion Price”) equal to the amount in the Trust Fund (inclusive of any interest income therein) calculated as of two business days prior to the consummation of the proposed Business Combination divided by the total number of IPO Shares. If holders of less than 20% in interest of the Company’s IPO Shares elect to convert their IPO Shares, the Company may, but will not be required to, proceed with such Business Combination. If the Company elects to so proceed, it will convert shares, based upon the Conversion Price, from those holders of IPO Shares who affirmatively requested such conversion and who voted against the Business Combination. If holders of 20% or more in interest of the IPO Shares, who vote against approval of any potential Business Combination, elect to convert their IPO Shares, the Company will not proceed with such Business Combination and will not convert such shares.

(x) Rule 419. The Company agrees that it will use its best efforts to prevent the Company from becoming subject to Rule 419 under the 1933 Act prior to the consummation of any Business Combination, including but not limited to using its best efforts to prevent any of the Company’s outstanding securities from being deemed to be a “penny stock” as defined in Rule 3a-51-1 under the 1934 Act during such period.

(y) Target Net Assets. The Company agrees that the initial Target Business that it acquires must have a fair market value equal to at least 80% of the Company’s net assets at the time of such acquisition. The fair market value of such business must be determined by the Board of Directors of the Company based upon standards generally accepted by the financial community, such as actual and potential sales, earnings and cash flow and book value. If the Board of Directors of the Company is not

able to independently determine that the target business has a fair market value of at least 80% of the Company’s fair market value at the time of such acquisition, the Company will obtain an opinion from an unaffiliated, independent investment banking firm which is a member of the NASD with respect to the satisfaction of such criteria. The Company is not required to obtain an opinion from an investment banking firm as to the fair market value if the Company’s Board of Directors independently determines that the Target Business does have sufficient fair market value.

(a) Expenses. The Company will pay all expenses incident to the performance of its obligations under this Agreement, including (i) the preparation, printing and filing of the Registration Statement (including financial statements and exhibits) as originally filed and of each amendment thereto, (ii) the preparation, printing and delivery to the Underwriters of this Agreement, any Agreement among Underwriters and such other documents as may be required in connection with the offering, purchase, sale, issuance or delivery of the Securities, (iii) the preparation, issuance and delivery of the certificates for the Securities to the Underwriters, including any stock or other transfer taxes and any stamp or other duties payable upon the sale, issuance or delivery of the Securities to the Underwriters, (iv) the fees and disbursements of the Company’s counsel, accountants and other advisors, (v) the qualification of the Securities under securities laws in accordance with the provisions of Section 3(f) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection therewith and in connection with the preparation of the Blue Sky Survey and any supplement thereto, (vi) the printing and delivery to the Underwriters of copies of each preliminary prospectus and of the Prospectus and any amendments or supplements thereto, (vii) the preparation, printing and delivery to the Underwriters of copies of the Blue Sky Survey and any supplement thereto, (viii) the fees and expenses of any of the escrow agent, trustee, transfer agent or registrar, and warrant agent for the Securities, (ix) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the Securities, including without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and the cost of aircraft and other transportation chartered in connection with the road show. (x) the filing fees incident to, and the reasonable fees and disbursements of counsel to the Underwriters in connection with, the review by the NASD of the terms of the sale of the Securities and (xi) all other costs and expenses customarily borne by an issuer incident to the performance of its obligations hereunder.

(b) Nonaccountable Expenses. The Company further agrees that, in addition to the expenses payable pursuant to paragraph (a) above, at the Closing Time, it will pay to the Representative a nonaccountable expense allowance equal to one percent (1.0%) of the gross proceeds received by the Company from the sale of the Initial Units, by deduction from the proceeds of the offering contemplated herein.

(c) Expenses Related to Business Combination. The Company further agrees that, in the event the Representative assists the Company in trying to obtain stockholder approval of a proposed Business Combination, the Company agrees to reimburse the Representative for all out-of-pocket expenses, including, but not limited to, “road-show” and due diligence expenses.

(d) Termination of Agreement. If this Agreement is terminated by the Representative in accordance with the provisions of Section 5 or Section 9(a)(i) hereof, the Company shall reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters.

SECTION 5. Conditions of Underwriters’ Obligations. The obligations of the several Underwriters hereunder are subject to the accuracy of the representations and warranties of the Company contained in Section 1 hereof or in certificates of any officer of the Company of the Company delivered pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder, and to the following further conditions:

In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York, the federal law of the United States and the General Corporation Law of the State of Delaware, upon the opinions of counsel satisfactory to the Representative. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and certificates of public officials.

(d) Officers’ Certificate. At Closing Time, there shall not have been, since the date hereof or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company, whether or not arising in the ordinary course of business, and the Representative shall have received a certificate of the President or a Vice President of the Company and of the chief financial or chief accounting officer of the Company, dated as of Closing Time, to the effect that (i) there has been no such material adverse change, (ii) the representations and warranties in Section 1(a) hereof are true and correct with the same force and effect as though expressly made at and as of Closing Time, (iii) the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to Closing Time, and (iv) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending or, to their knowledge, contemplated by the Commission.

(j) Conditions to Purchase of Option Units. In the event that the Underwriters exercise their option provided in Section 2(b) hereof to purchase all or any portion of the Option Units, the representations and warranties of the Company contained herein and the statements in any certificates furnished by the Company hereunder shall be true and correct as of each Date of Delivery and, at the relevant Date of Delivery, the Representative shall have received:

(a) Indemnification of Underwriters. (1) The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, as such term is defined in Rule 501(b) under the 1933 Act (each, an “Affiliate”), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company;

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by FTN), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through FTN expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(2) In addition to and without limitation of the Company’s obligation to indemnify the Independent Underwriter as an Underwriter, the Company also agrees to indemnify and hold harmless the Independent Underwriter, its Affiliates and selling agents and each person, if any, who controls the Independent Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage, and expense whatsoever, as incurred, incurred as a result of the Independent Underwriter’s participation as a “qualified independent underwriter” within the meaning of Rule 2720 of the Conduct Rules of the NASD in connection with the offering of the Securities.

(3) Insofar as this indemnity agreement may permit indemnification for liabilities under the 1933 Act of any person who is a partner of an Underwriter or who controls an underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and who, at the date of this Agreement, is a director or officer of the Company or controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, such indemnity agreement is subject to the undertaking of the Company in the Registration Statement under Item 17 thereof.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through FTN expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by FTN, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances; provided, that, if indemnity is sought pursuant to Section 6(a)(2), then, in addition to the fees and expenses of such counsel for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one counsel (in addition to any local counsel) separate from its own counsel and that of the other indemnified parties for the Independent Underwriter in its capacity as a “qualified independent underwriter” and all persons, if any, who control the Independent Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of 1934 Act in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances if, in the reasonable judgment of the Independent Underwriter, there may exist a conflict of interest between the Independent Underwriter and the other indemnified

parties. Any such separate counsel for the Independent Underwriter and such control persons of the Independent Underwriter shall be designated in writing by the Independent Underwriter. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a) (ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in

investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Units set forth opposite their respective names in Schedule A hereto and not joint.

Title:

For itself and as Representative of the other Underwriters named in Schedule A hereto.

1. The initial public offering price per Unit, determined as provided in said Section 2, shall be $6.00.

The purchase price per unit for the Units to be paid by the several Underwriters shall be $5.52, being an amount equal to the initial public offering price set forth above less $0.48 per Unit; provided that the purchase price per Unit for any Option Units purchased upon the exercise of the overallotment option described in Section 2(b) shall be reduced by an amount per Unit equal to any dividends or distributions declared by the Company and payable on the Initial Units but not payable on the Option Units.

(i) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware.

(ii) The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and to enter into perform its obligations under the Underwriting Agreement.

(iii) The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

(iv) The authorized, issued and outstanding capital stock of the Company is as set forth in the Prospectus in the column entitled “Actual” under the caption “Capitalization” (except for subsequent issuances, if any, pursuant to the Underwriting Agreement or pursuant to reservations, agreements or employee benefit plans referred to in the Prospectus or pursuant to the exercise of convertible securities or options referred to in the Prospectus); the shares of issued and outstanding capital stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable; and none of the outstanding shares of capital stock of the Company was issued in violation of the preemptive or other similar rights of any securityholder of the Company.

(v) The Securities have been duly authorized for issuance and sale to the Underwriters pursuant to the Underwriting Agreement and, when issued and delivered by the Company pursuant to the Underwriting Agreement against payment of the consideration set forth in the Underwriting Agreement, will be validly issued and fully paid and non-assessable and no holder of the Securities is or will be subject to personal liability by reason of being such a holder.

(vi) The issuance of the Securities is not subject to preemptive or other similar rights of any securityholder of the Company.

(viii) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(ix) The Registration Statement, including any Rule 462(b) Registration Statement, has been declared effective under the 1933 Act; any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); and, to the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or threatened by the Commission.

(x) The Registration Statement, including any Rule 462(b) Registration Statement and the Rule 430A Information, the Prospectus and each amendment or supplement to the Registration Statement and Prospectus as of their respective effective or issue dates (other than the financial statements and supporting schedules included therein or omitted therefrom, as to which we need express no opinion) complied as to form in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations.

(xi) The form of certificate used to evidence the Common Stock complies in all material respects with all applicable statutory requirements, with any applicable requirements of the charter and by-laws of the Company

(xii) To the best of our knowledge, there is not pending or threatened any action, suit, proceeding, inquiry or investigation, to which the Company is a party, or to which the property of the Company is subject, before or brought by any court or governmental agency or body, domestic or foreign, which would reasonably be expected to result in a Material Adverse Effect, or which would reasonably be expected to materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the Underwriting Agreement or the performance by the Company of its obligations thereunder.

(xiii) The information in the Prospectus under “Description of Securities” and in the Registration Statement under Item 14, to the extent that it constitutes matters of law, summaries of legal matters, the Company’s charter and bylaws or legal proceedings, or legal conclusions, has been reviewed by us and is correct in all material respects [and the opinion of such firm set forth under “Certain Federal Income Tax Considerations” is confirmed].

(xiv) All descriptions in the Registration Statement of contracts and other documents to which the Company is a party are accurate in all material respects; to the best of our knowledge, there are no franchises, contracts, indentures, mortgages, loan agreements, notes, leases or other instruments required to be described or referred to in the Registration Statement or to be filed as exhibits to the Registration Statement other than those described or referred to therein or filed as exhibits thereto.

(xv) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign (other than under the 1933 Act and the 1933 Act Regulations, which have been obtained, or as may be required under the securities or blue sky laws of the various states, as to which we need express no opinion) is necessary or required in connection with the due authorization, execution and delivery of the Underwriting Agreement or for the offering, issuance, sale or delivery of the Securities.

(xvi) The execution, delivery and performance of the Underwriting Agreement and the consummation of the transactions contemplated in the Underwriting Agreement and in the Registration Statement (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Prospectus under the caption “Use Of Proceeds”) and compliance by the Company with its obligations under the Underwriting Agreement do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined in Section 1(a)(xii) of the Underwriting Agreement) under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument, known to us, to which the Company is a party or by which it or any of them may be

bound, or to which any of the property or assets of the Company is subject, nor will such action result in any violation of the provisions of the charter or by-laws of the Company, or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to us, of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its properties, assets or operations.

(xvii) To the best of our knowledge, there are no persons with registration rights or other similar rights to have any securities registered pursuant to the Registration Statement or otherwise registered by the Company under the 1933 Act.

(xviii) The Company is not required, and upon the issuance and sale of the Securities as herein contemplated and the application of the net proceeds therefrom as described in the Prospectus will not be required, to register as an “investment company” under the 1940 Act.

Nothing has come to our attention that would lead us to believe that the Registration Statement or any amendment thereto, including the Rule 430A Information, (except for financial statements and schedules and other financial data included therein or omitted therefrom, as to which we need make no statement), at the time such Registration Statement or any such amendment became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus or any amendment or supplement thereto (except for financial statements and schedules and other financial data included therein or omitted therefrom, as to which we need make no statement), at the time the Prospectus was issued, at the time any such amended or supplemented prospectus was issued or at the Closing Time, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, such counsel may rely as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).
