Re: Initial Public Offering

Gentlemen:

KrisLee & Associates, LLC (“KrisLee”), a stockholder of Oakmont Acquisition Corp. (“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 9 hereof):

1. If the Company solicits approval of its stockholders of a Business Combination, KrisLee will vote all Insider Shares owned by it in accordance with the majority of the votes cast by the holders of the IPO Shares.

2. KrisLee will escrow its Insider Shares for the three year period commencing on the Effective Date subject to the terms of a Stock Escrow Agreement which the Company will enter into with KrisLee and an escrow agent acceptable to the Company.

3. 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), KrisLee will take all reasonable actions within its power to cause the Company to liquidate as soon as reasonably practicable. KrisLee hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any distribution of the Trust Fund (as defined in the Letter of Intent) with respect to KrisLee’s Insider Shares and waives any Claim KrisLee 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.

4. KrisLee 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 Morgan Joseph that the business combination is fair to the Company’s stockholders from a financial perspective.

5. Neither KrisLee, or any member, officer, director, employee or any affiliate of KrisLee, will be entitled to receive or accept a finder’s fee or any other compensation in the event KrisLee, or any member, officer, director, employee or any affiliate thereof originates a Business Combination.

6. KrisLee’s Questionnaire furnished to the Company and annexed as Exhibit A hereto is true and accurate in all respects.

7. KrisLee has full right and power, without violating any agreement by which it is bound, to enter into this letter agreement.

8. Neither KrisLee, or any member, officer, director, employee or any affiliate of KrisLee, 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 KrisLee shall be entitled to reimbursement from the Company for its out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination.
