RE:      INITIAL PUBLIC OFFERING

Gentlemen:

The undersigned stockholder, officer, director or senior advisor of Harbor
Business Acquisition Corp. ("Company"), in consideration of H.C. Wainwright &
Co., Inc. ("H.C. Wainwright") entering into a letter of intent ("Letter of
Intent") to underwrite an initial public offering of the securities of the
Company ("IPO") and embarking on the IPO process, hereby agrees as follows
(certain capitalized terms used herein are defined in paragraph 15 hereof):

1. If the Company solicits approval of its stockholders of a Business
Combination, the undersigned will cause Harbor Healthcare Holding LLC to vote
(i) all Insider Shares owned by it in accordance with the majority of the votes
cast by the holders of the IPO Shares, (ii) all of the shares that may be
acquired by it in the Private Placement, the IPO or in the aftermarket for the
Business Combination and (iii) all Insider Shares and all shares that may be
acquired by it in the Private Placement, the IPO or in the aftermarket for an
amendment to the Company's Certificate of Incorporation to provide for perpetual
existence of the Company in the event the Business Combination is approved.

2. In the event that the Company fails to consummate a Business Combination
within twenty-four-month period immediately following the date of the prospectus
related to the IPO (such date being referred to herein as the "Termination
Date"), the undersigned shall (i) cause the Trust Fund (as defined in the Letter
of Intent) to be liquidated and distributed to the holders of IPO Shares and
(ii) take all reasonable actions within his power to cause the Company to
liquidate as soon as reasonably practicable pursuant to the requirements of the
Delaware General Corporation Law. The undersigned hereby waives any and all
right, title, interest or claim of any kind ("Claim") in or to any liquidating
distributions by the Company, including, without limitation, any distribution of
the Trust Fund (as defined in the Letter of Intent), as a result of such
liquidation with respect to his Insider Shares and the Private Placement Shares
and hereby waives any Claim the undersigned may have in the future as a result
of, or arising out of, any contracts or agreements with the Company and will not
seek recourse against the Trust Fund for any reason whatsoever.

3. In the event of the liquidation of the Trust Fund, the undersigned agrees to
indemnify and hold harmless the Company against any and all loss, liability,
claims, damage and expense whatsoever (including, but not limited to, any and
all legal or other expenses reasonably incurred in investigating, preparing or
defending against any litigation, whether pending or threatened, or any claim
whatsoever) to which the Company may become subject as a result of any claim by
any vendor, prospective target business or other entity that is owed money by
the Company for services rendered or products sold but only to the extent
necessary to ensure that such loss, liability, claim, damage or expense does not
reduce the amount in the Trust Fund. In the event that the Company does not
consummate a business combination and must distribute to its public stockholders
the amount in its trust account (including any accrued interest) plus any
remaining net assets, and if such funds are insufficient to complete such
liquidation, the undersigned agrees to advance such funds necessary to complete
such liquidation (currently anticipated to be no more than approximately
$15,000) and agrees not to seek repayment for such expenses.

4. In order to minimize potential conflicts of interest which may arise from
multiple affiliations, the undersigned agrees to present to the Company for its
consideration, and not to any other person or entity unless the opportunity is
rejected by the Company, those opportunities to acquire an operating company the
undersigned reasonably believes are suitable opportunity for the Company, until
the earlier of the consummation by the Company of a Business Combination, the
dissolution and liquidation of the Company or until such time as the undersigned
ceases to be an officer or director of the Company, subject to any pre-existing
fiduciary obligations the undersigned might have.

5. The undersigned acknowledges and agrees that the Company will not consummate
any Business Combination which involves a company which is affiliated with any
of the Insiders unless the Company obtains an opinion from an independent
investment banking firm reasonably acceptable to H.C. Wainwright that the
business combination is fair to the Company's stockholders from a financial
perspective.

6. Except for monthly payments of $7,500 to be made to Harbor Business Group,
LLC for administrative payments and for any repayments of principal and interest
on the Convertible Loans pursuant to the terms thereof in effect on the closing
date of the IPO, or from the funds outside of the Trust Fund neither the
undersigned, any member of the family of the undersigned, nor any affiliate of
the undersigned ("Affiliate") will be entitled to receive and will not accept
any compensation for services rendered to the Company prior to the consummation
of the Business Combination; provided that the undersigned shall be entitled to
receive reimbursement from the Company for his out-of-pocket expenses incurred
in connection with seeking and consummating a Business Combination.

7. Neither the undersigned, any member of the family of the undersigned, nor any
Affiliate of the undersigned will be entitled to receive or accept a finder's
fee or any other compensation in the event the undersigned, any member of the
family of the undersigned or any Affiliate of the undersigned originates a
Business Combination.
