Exhibit 10.6

[FORM OF INDEMNIFICATION AGREEMENT]

This INDEMNIFICATION AGREEMENT, made and entered into this                      day of                     , 2006 (“Agreement”), by and between MARATHON ACQUISITION CORP., a Delaware corporation (the “Company”) and the undersigned (“Indemnitee”).

WHEREAS, highly competent persons are becoming more reluctant to serve corporations as directors or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation, and

WHEREAS, the Board of Directors of the Company has determined that the inability to attract and retain such persons is detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; and

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; and

WHEREAS, Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified;

NOW, THEREFORE, in consideration of the promises, conditions, representations and warranties set forth herein, including Indemnitee’s continued service to the Company, the Company and Indemnitee hereby covenant and agree as follows:

4.04 Indemnification For Expenses of a Witness. Notwithstanding any other provision of this Agreement to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness in a Proceeding, Indemnitee shall be indemnified against all Losses and Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith.

ARTICLE VI

PROCEDURES FOR DETERMINATION OF ENTITLEMENT

The Secretary of the Company shall promptly advise the Board in writing that Indemnitee has requested indemnification.

6.02 D&O Insurance. If, at the time of the receipt of such notice, the Company has D&O Insurance in effect, the Company shall give prompt notice of the commencement of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies in favor of Indemnitee. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all Losses and Expenses payable as a result of such Proceeding in accordance with the terms of such policies.

6.03 Employment of Counsel. To the extent the Company does not, at the time of the commencement of or the threat of commencement of a Proceeding, have applicable D&O Insurance, or if a Determination is made that any Expenses arising out of such Proceeding will not be payable under the D&O Insurance then in effect, the Company shall be obligated to pay the Expenses of any such Proceeding in advance of the final disposition thereof as provided in Article V and the Company, if appropriate, shall be entitled to assume the defense of such Proceeding, with counsel satisfactory to Indemnitee, upon the delivery to Indemnitee of written notice of its election so to do. After delivery of such notice, the Company will not be liable to Indemnitee under this Agreement for any legal or other Expenses subsequently incurred by Indemnitee in connection with such defense other than reasonable Expenses of investigation provided that Indemnitee shall have the right to employ its own counsel in any such Proceeding but the fees and expenses of such counsel incurred after delivery of notice from the Company of its assumption of such defense shall be at Indemnitee’s expense and provided further that if (i) the employment of counsel by Indemnitee has been previously authorized by the Company, (ii) Indemnitee and counsel shall have reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense or (iii) the Company shall not, in fact, have employed counsel to assume the defense of such Proceeding, the fees and expenses of counsel shall be at the expense of the Company.

6.04 Payment. All payments on account of the Company’s indemnification obligations under this Agreement shall be made within sixty (60) days of Indemnitee’s written request therefor unless a Determination is made that the claims giving rise to Indemnitee’s request are Excluded Claims or otherwise not payable under this Agreement or applicable law.

6.05 Reimbursement by Indemnitee. Indemnitee agrees that he or she will reimburse the Company for all Losses and Expenses paid by the Company in connection with any Proceeding against Indemnitee in the event and only to the extent that a Determination shall have been made by a court in a final adjudication from which there is no further right of appeal that Indemnitee is not entitled to be indemnified by the Company for such Expenses because the claim is an Excluded Claim or because Indemnitee is otherwise not entitled to payment under this Agreement.

6.06 Cooperation. Indemnitee shall cooperate with the person, persons or entity making the Determination with respect to Indemnitee’s entitlement to indemnification under this Agreement, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such Determination. Any costs or Expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such Determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.
