Re:          Initial Public Offering

Gentlemen:

The undersigned officer of HD Partners Acquisition Corporation (“Company”), in consideration of Morgan Joseph & Co. Inc. (“Morgan Joseph”) 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 13 hereof):

1.             In the event that the Company fails to consummate a Business Combination within 18 months from the effective date (“Effective Date”) of the registration statement relating to the IPO (or 24 months under the circumstances described in the prospectus relating to the IPO), the undersigned will (i) cause the Trust Fund (as defined in the Letter of Intent) to return capital held in the Trust Fund to the holders of IPO Shares and (ii) take all reasonable actions within his power to cause the Company to dissolve as soon as reasonably practicable. The undersigned hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any rights in the Trust Fund, except with respect to any of the IPO Shares, as defined herein, acquired by the undersigned in connection with or following the IPO, and any remaining net assets of the Company as a result of such return of capital held in the Trust Fund and dissolution of the Company 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. 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) 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 provided that the Company did not obtain a waiver from such party of its rights or claims to the Trust Fund and only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount in the Trust Fund (as defined in the Letter of Intent).

2.             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, prior to presentation to any other person or entity, any suitable opportunity to acquire an operating business, until the earlier of the consummation by the Company of a Business Combination, the dissolution of the Company or until such time as the undersigned ceases to be an officer of the Company, subject to any pre-existing fiduciary and contractual obligations the undersigned might have.

3.             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 which is a member of the National Association of Securities Dealers, Inc. and is reasonably acceptable to Morgan Joseph that the Business Combination is fair to the Company’s stockholders from a financial perspective.

4.             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 commencing on the Effective Date, Value Investments, LLC (“Related Party”), shall be allowed to charge the Company an allocable share of Related Party’s overhead, up to $7,500 per month, to compensate it for the Company’s use of Related Party’s office space, utilities, administrative, technology and secretarial services. Related Party and the undersigned shall also be entitled to reimbursement from the Company for their out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination.

5.             Neither the undersigned, any member of the family of the undersigned, nor any Affiliate 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 originates a Business Combination.
