                          , 2006 
  
 FTN Midwest Securities Corp.

	Re:	Healthcare Acquisition Partners Corp. 

  
 Gentlemen: 
  
 This letter will confirm the agreement among FTN Midwest Securities Corp. (“FTN”) and Sean McDevitt, Pat LaVecchia, John Voris,
Jean-Pierre Millon, Erin Enright and Wayne Yetter (the “Management Members”) whereby the Management Members agree to purchase warrants (“Warrants”) of Healthcare Acquisition Partners Corp.
(“Company”) included in the units (“Units”) being sold in the Company’s initial public offering (“IPO”) upon the terms and conditions set forth herein. Each Unit is
comprised of one share of Common Stock and two Warrants. The shares of Common Stock and Warrants will not be separately tradable until the earlier of 65 days after the effective date of the Company’s IPO or 20 days after the exercise in full by
the underwriters of the underwriters’ over-allotment option in connection with the IPO. 
  
 The Management Members agree that on the date hereof they will enter into an agreement or plan in accordance with the guidelines specified by Rules 10b5-1 under the Securities Exchange Act of 1934, as amended
(“Exchange Act”), with an independent broker-dealer (the “Broker”) registered under Section 15 of Exchange Act which is neither affiliated with the Company, FTN nor part of the underwriting or
selling group, pursuant to which the Management Members place an irrevocable order for the Management Members to collectively purchase through the Broker for the account or accounts of the Management Members, within the sixty trading-day period
commencing on the later of (i) the date separate trading of the Warrants commences and (ii) the date that is 90 days after the end of the “restricted period” under Regulation M as determined by FTN (“Commitment
Date”), up to $1,000,000 (“Commitment Amount”) of Warrants in the open market (“Warrant Purchase”). The Management Members shall instruct the Broker to fill such order in such amounts and
at such times as the Broker may determine, in its sole discretion, during the sixty trading-day period described above. 







 If at the end of such sixty trading-day period the Broker has not purchased up to the Commitment Amount
on behalf of the Management Members, then the Management Members agree to purchase Warrants from the Company in a private placement at a price per Warrant to be agreed upon, but in no event less than $0.70 per warrant, in an amount equal to the
difference of the Commitment Amount and the total amount paid by the Broker. 
  
 The Management Members agree that they may not sell or transfer any Warrants purchased pursuant to this agreement until after the Company consummates a business combination, as discussed in the prospectus in
connection with the IPO. 
  
 Sean McDevitt and Pat LaVecchia each
agree not to purchase Warrants if the aggregate number of (a) shares of Common Stock purchased in the open market and owned by FTN and its affiliates, plus (b) Warrants and shares of Common Stock comprising any Units purchased in
the open market and owned by FTN and its affiliates, plus (c) the 833,333 shares of Common Stock subject to FTN’s purchase option granted by the Company in connection with the IPO (“Purchase Option”),
plus (d) Warrants to be purchased in the open market and owned by FTN’s affiliates under the agreement set forth in this letter would exceed 9.00% of the total number of shares of Common Stock then outstanding (assuming exercise in
full of the Purchase Option and any such Warrants). 
  
 Each of
the Management Members represents and warrants that he is not aware of any material nonpublic information concerning the Company or any securities of the Company and is entering into this agreement in good faith and not as part of a plan or scheme
to evade the prohibitions of Rule 10b5-1. Each of the Management Members agrees that while this agreement is in effect, he or she shall comply with the prohibition set forth in Rule 10b5-1(c)(1)(i)(C) against entering into or altering a
corresponding or hedging transaction or position with respect to the Company’s securities. Each of the Management Members each further agrees that he or she shall not, directly or indirectly, communicate any material nonpublic information
relating to the Company or the Company’s securities to any employee of the Broker. Each of the Management Members hereby confirms that he or she does not have, and shall not attempt to exercise, any influence over how, when or whether to effect
purchases by the Broker of Warrants pursuant to this agreement. 
  
 This agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to conflict of laws.
