Board of Directors and Committees of the Board of Directors

The Board of Directors has responsibility for the overall governance of HAPC. The Board of Directors held a total of 9 meetings during the fiscal year ended December 31, 2006. Each incumbent director attended at least 75% of the meetings held by the Board of Directors. In addition to regularly scheduled meetings, the directors discharge their responsibilities through telephonic and other communications with each other and the executive officers. All of the directors are expected to attend the 2007 annual stockholders meeting.

HAPC’s Board of Directors has established an Audit Committee to devote attention to specific subjects and to assist the Board of Directors in the discharge of its responsibilities. HAPC does not currently have a Compensation Committee or Nominating and Governance Committee. The Board of Directors does not believe that any marked efficiencies or enhancements would be achieved by the creation of a separate Compensation Committee or Nominating and Governance Committee.

The duties and responsibilities typically delegated to a Nominating and Governance Committee are included in the responsibilities of the entire Board of Directors. The Board of Directors identifies nominees by first evaluating the current members of the Board of Directors willing to continue in service. If any member of the Board of Directors does not wish to continue in service or if the Board of Directors decides not to re-nominate a member for re-election, the Board will consider all qualified director candidates identified by members of the Board, by senior management and stockholders. Stockholders who would like to propose an independent director candidate for consideration by the Board of Directors may do so by submitting the candidate’s name, résumé and biographical information to the attention of Pat LaVecchia, Secretary, HAPC, INC., 350 Madison Avenue, 20th Floor, New York, New York 10017. All proposals for nomination received by the Secretary will be presented to the Board of Directors for consideration.

The Board of Directors reviews each director candidate’s biographical information and assesses each candidate’s independence, skills and expertise based on a variety of factors, including the following criteria:

Application of these factors requires the exercise of judgment by members of the Board of Directors and cannot be measured in a quantitative way.

Table of Contents

The Board of Directors of HAPC has not formed a Compensation Committee because it does not pay any of its executive officers a regular salary. The duties and responsibilities typically delegated to a Compensation Committee are included in the responsibilities of the entire Board of Directors.

The Board of Directors has established an Audit Committee, which reports to the Board of Directors. The Audit Committee is responsible for meeting with HAPC’s independent registered accounting firm regarding, among other issues, audits and adequacy of HAPC’s accounting and control systems. In addition, the Audit Committee monitors compliance on a quarterly basis with the terms of HAPC’s initial public offering consummated on April 18, 2006. If any noncompliance is identified, the Audit Committee has the responsibility to take immediately all action necessary to rectify such noncompliance or otherwise cause compliance with the terms of HAPC’s initial public offering. The Audit Committee held 4 meetings during the fiscal year ended December 31, 2006. Each member of the Audit Committee attended all of the meetings.

The Audit Committee is composed entirely of independent directors. The following individuals are members of HAPC’s Audit Committee: Jean-Pierre Millon and Wayne Yetter. Due to the affiliation of Messrs. McDevitt and LaVecchia with FTN Midwest Securities Corp., the underwriter of HAPC’s initial public offering, to the extent FTN Midwest Securities is acting as HAPC’s 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 HAPC’s Audit Committee is an “audit committee financial expert” as that term is defined under Item 401 of Regulation S-K of the Exchange Act, but nonetheless, HAPC believes the members are qualified to perform their duties.

Communications with the Board of Directors

The stockholders may communicate with the Board of Directors and executive officers, by sending written communications addressed to such person or persons in care of HAPC, INC., 350 Madison Avenue, 20th Floor, New York, New York 10017. All communications will be compiled by the Secretary and submitted to the addressee.

Code of Conduct and Ethics

HAPC has adopted a code of conduct and ethics applicable to its directors, officers and employees in accordance with applicable federal securities laws. Stockholders may obtain copies of the code of conduct and ethics free of charge by sending a request in writing to HAPC, INC., 350 Madison Avenue, 20th Floor, NY, NY 10017, Attn: Secretary.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires HAPC’s officers and directors and persons who beneficially own more than 10% of HAPC’s common stock to file initial reports of ownership of such securities and reports of changes in ownership of such securities with the U.S. Securities and Exchange Commission (the “SEC”). Such officers, directors and 10% stockholders of HAPC are also required by SEC regulations to furnish HAPC with copies of all Section 16(a) forms they file.

Based solely on HAPC’s review of the copies of such forms received by it with respect to fiscal year 2006, all reports were filed on a timely basis except for the report by Sean McDevitt, HAPC’s chairman, with respect to his purchase of 624,286 warrants from HAPC for an aggregate purchase price of $437,000 on December 28 2006.

Compensation Discussion and Analysis

The Board of Directors of HAPC has not formed a Compensation Committee because it does not pay any of its executive officers a regular salary. The duties and responsibilities typically delegated to a Compensation Committee are included in the responsibilities of the entire Board of Directors. The foundation of HAPC’s compensation policy is that compensation paid to executive officers should be aligned on a long and short term basis. The general compensation policy of the Board of Directors is that total compensation should be tied to individual performance and supplemented with awards tied to HAPC’s performance in achieving financial and non-financial objectives. Upon the consummation of HAPC’s acquisition of InfuSystem, Inc. (“InfuSystem”) pursuant to the terms of that certain Stock Purchase Agreement, dated as of September 29, 2006, by and among Iceland Acquisition Subsidiary, Inc., a wholly owned subsidiary of HAPC, HAPC, InfuSystem, a wholly owned subsidiary of I-Flow Corporation (“I-Flow”) and I-Flow, HAPC will commence paying its officers regular salaries. Provided that the 2007 HAPC Stock Incentive Plan (the “Plan”) is adopted by the stockholders at the 2007 annual stockholders meeting, HAPC’s officers will become eligible for grants under the Plan.

Summary Compensation Table

The following table summarizes the compensation of the executive officers of HAPC for the fiscal years ended December 31, 2006 and December 31, 2005.

HAPC’s officers receive reimbursement for any out-of-pocket expenses incurred in connection with activities on HAPC’s behalf such as identifying potential acquisition 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 is no review of the reasonableness of the expenses by anyone other than the Board of Directors of HAPC, 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 are used to reimburse out-of-pocket expenses prior to a business combination.

As of April 3, 2007, HAPC had reimbursed $9,331.16 in expenses to Erin Enright for travel and legal expenses in connection with the initial public offering and acquisition of InfuSystem as well as attendance at certain meetings of the Board of Directors.

Board of Directors Acting as Compensation Committee and Compensation Committee Interlocks and Insider Participation

The Board of Directors of HAPC has not established a Compensation Committee. A majority of the independent directors of the Board of Directors will determine the compensation of the executive officers. Jean Pierre Millon and Wayne Yetter are the independent directors of the Board of Directors of HAPC. Neither of them was, or has been, an officer or employee of HAPC, or has a relationship that would constitute an interlocking relationship with executive officers or directors of HAPC or another entity.

The following table sets forth information regarding the beneficial ownership of the common stock of HAPC as of April 11, 2007 which amount includes shares of common stock which may be acquired by such persons within 60 days of the filing of this Form 10-K/A:

All of the common stock issued to these individuals will vest upon completion of the acquisition of InfuSystem.

HAPC granted a purchase option to FTN Midwest Securities Corp. at the closing of the initial public offering on April 18, 2006 to acquire 833,333 units for $100. Similar to the units issued in connection with the initial public offering, the units issuable upon exercise of the purchase option consist of one share of common stock and one warrant. Each warrant underlying the purchase option, however, entitles the holder to purchase one share of our common stock at a price of $6.25 per share. The purchase 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. Additionally, the terms of the purchase option provide that: (i) HAPC is not obligated to deliver any securities pursuant to the exercise of the purchase option unless a registration statement under the Securities Act of 1933, as amended, with respect to the common stock issuable upon exercise of the warrants which are issuable upon exercise of the purchase option is effective; and (ii) FTN is not entitled to receive a net-cash settlement or other consideration in lieu of physical settlement in securities if the common stock issuable upon exercise of the warrants is not covered by an effective registration statement.

Securities Authorized for Issuance Under Equity Compensation Plans

HAPC does not currently have any authorized or outstanding equity compensation plans.

Sean McDevitt is the chairman of HAPC’s Board of Directors and Pat LaVecchia is HAPC’s Secretary and a member of HAPC’s Board of Directors. Sean McDevitt and Pat LaVecchia were previously managing directors of FTN Midwest Securities Corp., the underwriter of HAPC’s initial public offering and advisor in connection with the acquisition of InfuSystem. Mr. McDevitt resigned from his position as a managing director of FTN Midwest Securities Corp. effective January 19, 2007 and Mr. LaVecchia resigned from his position as a managing director of FTN Midwest Securities Corp. effective February 2, 2007.

HAPC has entered into an agreement with FTN Midwest Securities Corp. under the terms of which FTN Midwest Securities Corp. will make available to HAPC certain administrative, technology and secretarial services, as well as the use of certain limited office space, including a conference room, in the New York area as may be required by HAPC from time to time, situated at 350 Madison Avenue, 20th Floor, New York, New York, or any successor location. Such services will be of the same quality and condition as made available by FTN Midwest Securities Corp. to itself, provided that no disruption of FTN Midwest Securities Corp.’s day-to-day business will result from the provision of the services. In exchange therefor, HAPC will pay FTN Midwest Securities Corp. the sum of $1 per year.

HAPC has entered into agreements with FTN Midwest Securities Corp. and Sean McDevitt and Pat LaVecchia, under the terms of which each of them has agreed to present to HAPC for its 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 HAPC 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 opportunity to consider the acquisition of InfuSystem was presented to HAPC by FTN Midwest Securities Corp. pursuant to this agreement.

HAPC has sold to FTN Midwest Securities Corp., for $100, an option to purchase up to a total of 833,333 units comprised of one share of common stock and two warrants. The units issuable upon exercise of the option are identical to those offered in HAPC’s initial public offering except that the warrants included in the option units have an exercise price of $6.25 (125% of the exercise price of the warrants included in the units sold in the initial public offering). This option is exercisable at $7.50 per unit commencing on the later of the consummation of a business combination and April 11, 2007.

None of HAPC’s officers and directors are required to commit their full time to its affairs and, accordingly, they may have conflicts of interest in allocating management time among various business activities.

In the course of their other business activities, HAPC’s officers and directors may become aware of investment and business opportunities which may be appropriate for presentation to HAPC as well as the other entities with which they are affiliated. For a complete description of HAPC’s management’s other affiliations, see “Item 10 – Directors, Executive Officers and Corporate Governance.”

HAPC’s officers and directors may in the future become affiliated with entities, including other blank check companies, engaged in business activities similar to those intended to be conducted by HAPC.

HAPC’s officers and directors (other than Messrs. McDevitt and LaVecchia) own shares of HAPC common stock, which are subject to forfeiture provisions and lock-up agreements restricting their sale until six months after a business combination is successfully completed. The shares owned by HAPC’s directors and officers will be worthless if HAPC does not consummate a business combination. Therefore, HAPC’s management may have a conflict of interest in determining whether a particular target business is appropriate to effect a business combination. The personal and financial interests of HAPC’s directors and officers may influence their motivation in identifying and selecting target businesses and completing a business combination in a timely manner.

Messrs. McDevitt and LaVecchia have, collectively, committed to purchase $1,000,000 of

warrants in the market at prevailing market prices or from HAPC at a price of $0.70 per warrant, subsequent to the preliminary filing of HAPC’s proxy statement relating to the acquisition of InfuSystem with the SEC.

On December 28, 2006, HAPC issued and sold to Sean McDevitt 624,286 warrants to purchase common stock at a purchase price of $0.70 per warrant for an aggregate purchase price of $437,000. Mr. McDevitt purchased the warrants on his own behalf. Each warrant represents the right to purchase one share of common stock at an exercise price of $5.00 per share. The warrants are exercisable commencing on the later of HAPC’s completion of a business combination or April 11, 2007, and expire on April 11, 2011 or earlier upon HAPC’s redemption of the warrants. HAPC may redeem the warrants in whole, and not in part, at a price of $0.01 per warrant, at any time after the warrants become exercisable, provided that Mr. McDevitt receives no less than 30 days written notice prior to the redemption and the last reported 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 Mr. McDevitt. The exercise price and number of shares of common stock issuable upon exercise of the warrants will be subject to future adjustments in the event that HAPC subdivides or combines its outstanding shares of common stock or issues a stock dividend. HAPC issued and sold to Mr. McDevitt an additional 447,143 warrants to purchase common stock at a purchase price of $0.70 per warrant for an aggregate purchase price of $313,000 as of April 12, 2007 (the date HAPC received payment for such warrants). These warrants are subject to the same terms and conditions as the warrants purchased by Mr. McDevitt in December 2006. To date, Mr. McDevitt has purchase 1,071,429 of warrants from HAPC at an aggregate purchase price of $750,000.

HAPC’s Board of Directors, with Messrs. McDevitt and LaVecchia not participating, have determined to grant to them 2,000,000 and 416,666 shares, respectively, of HAPC common stock. These shares will not be transferred until six months after the completion of a business combination or, if later, April 11, 2007.

HAPC’s officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers and directors were included by a target business as a condition to any agreement with respect to a business combination.

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:

Director Independence

Based upon information solicited from each nominee, the Board of Directors of HAPC has determined that Jean Pierre Millon and Wayne Yetter have no material relationship with HAPC (either directly or as a partner, stockholder or officer of an organization that has a relationship with HAPC) and are “independent” within the meaning of Nasdaq’s director independence standards and Audit Committee independence standards, as currently in effect.
