and Cypress Advisors, Inc., a Delaware corporation (Cypress).

1. Appointment. Each of Parent, Intermediate and the Company hereby retains Cypress to provide the advisory and
consulting services described in Section 2 hereof, commencing on the date hereof.

2. Services. Cypress hereby agrees
that, commencing on the date hereof, it shall provide to each of Parent, Intermediate and the Company (and their subsidiaries) the following advisory and consulting services as requested from time to time by any of Parent, Intermediate and the
Company (and their subsidiaries):

(a) advice in connection with the negotiation and consummation of
agreements, contracts, documents and instruments necessary to provide the Company with financing on terms and conditions satisfactory to the Company (including with respect to any initial public offering of the common stock of Parent);

(b) advice in connection with financing, acquisition, disposition, merger, business combination and change of control
transactions involving the Company or any of its subsidiaries (however structured), including transaction analysis and support services; and

(c) such other services (which may include financial and strategic planning and analysis) as may be requested from time to time.

Cypress will devote, in its discretion, such time and efforts to the performance of services contemplated hereby as Cypress deems reasonably necessary or appropriate;provided, however, that no

3. Fees.

(a) Parent, Intermediate and the Company hereby jointly and severally agree to pay Cypress a management fee (the
Quarterly Fee) equal to $100,000 per calendar quarter (to a maximum aggregate amount of $600,000) payable in advance on or before the first business day of the applicable quarter with the first payment due January 19, 2011. The
Quarterly Fee is payable until the first to occur of (i) payment in full of the Success Fee (defined in Section 3(b)) or (ii) June 30, 2012.

(b) Upon a Successful Liquidity Event (defined below), Parent, Intermediate and the Company hereby jointly and severally agree to pay a success fee (the "Success Fee") equal to $2 million plus the amount
of any Quarterly Fees that would have been paid through June 30, 2012 but which have not been paid as of the date of the Successful Liquidity Event. A Successful Liquidity Event shall occur at such time as the Stockholders (as
defined in the Stockholders Agreement dated November 30, 2004 as in effect on the date hereof) realize, or have the actual ability to realize (including, without limitation, through a right to elect cash consideration or the receipt of freely
transferable securities), a cash payment on their entire original investment equal to or greater than two times the amount of such investment (either through one or more private transactions or through sales on the public market). In the event that
a transaction occurs involving only a portion of such Shareholders original investment, a Success Fee may still be payable if such transaction, when aggregated with all other transactions, results in an average transaction value which equals
or exceeds the two times threshold on a per-share equivalent basis for all of such Shareholders original investment (meaning, for example, that if a transaction occurred for 25% of the shares comprising the original investment at a price equal
to 1.5 times the amount of such investment and a subsequent (or a prior) transaction occurred for 25% of the shares comprising the original investment at a price equal to 2.5 times the amount of such investment, and a subsequent (or a prior)
transaction occurred for the remaining 50% of the shares comprising the original investment at a price equal to or in excess of 2.0 times the amount of such investment, Cypress would be entitled to the Success Fee).

(c) No Success Fee is payable after termination of the Agreement on June 30, 2013; provided, however, if Parent or
the Stockholders execute a binding definitive agreement with a third party prior to June 30, 2013 relating to a transaction and that transaction is consummated with such third party after June 30, 2013 and results in a Successful Liquidity
Event within six months (6) months of the execution of the applicable agreement with such third party, the Success Fee shall be earned and payable hereunder.



---

(d) In no event shall Parent, Intermediate and the Company be obligated
collectively to pay any amounts pursuant to this Section 3 in excess of $2.6 million in the aggregate.

4.
Reimbursements. In addition to the Quarterly Fee and the Success Fee, Parent, Intermediate and the Company hereby jointly and severally agree to reimburse Cypress for its reasonable Out-of-Pocket Expenses incurred after the date hereof in connection
with the services provided to Parent, Intermediate and the Company (and their subsidiaries) pursuant to Section 2 hereof. For the purposes of this Agreement, the term Out of Pocket Expenses shall mean the amounts actually paid by
Cypress in connection with the services contemplated hereby, including (i) reasonable air travel expenses, (ii) reasonable hotel or other lodging expenses, (iii) reasonable business-related meal expenses, (iv) other reasonable
incidental travel-related expenses and (v) reasonable non-meal entertainment expenses approved in writing in advance by the Companys chief executive officer or chief financial officer. Out of Pocket Expenses shall not include any expenses
for third party professional services unless approved in writing in advance by the Companys chief executive officer or chief financial officer. All reimbursements for Out-of-Pocket Expenses shall be made promptly upon or as soon as practicable
after presentation by Cypress of an invoice therefor (together with reasonable supporting detail). Cypress agrees that it shall invoice the Company monthly for such Out-of-Pocket Expenses. The Company shall present a summary of such Out-of-Pocket
Expenses for review by the Audit Committee of the Board of Directors on a quarterly basis.

5. Indemnification; Limitation of
Liability. Parent, Intermediate and the Company hereby jointly and severally agree to indemnify and hold harmless Cypress, and its affiliates and partners, members, officers, directors, employees, agents, representatives, investors and stockholders
(each being an Indemnified Party) from and against any and all losses, claims, damages and liabilities of whatever kind or nature, joint or several, absolute, contingent or consequential, to which such Indemnified Party may become
subject under any applicable federal or state law, or any claim made by any third party, or otherwise, to the extent they relate to or arise out of the services contemplated by this Agreement or the engagement of Cypress pursuant to, and the
performance by Cypress of the services contemplated by, this Agreement (including, without limitation, any cost and expenses incurred by an Indemnified Party to successfully enforce the provisions of this Section 5). Parent, Intermediate and
the Company hereby jointly and severally agree to reimburse any Indemnified Party for all reasonable costs and expenses (including reasonable attorneys fees and expenses) as they are incurred in connection with the investigation of,
preparation for or defense of any pending or threatened claim for which the Indemnified Party would be entitled to indemnification under the terms of the previous sentence, or any action or proceeding arising therefrom, whether or not such
Indemnified Party is a party hereto. Cypress represents and warrants to the Company on a continuing basis through the termination of this Agreement that none of the Indemnified Parties is a director, officer or employee of the Company (or an entity
controlled by the Company or any of the foregoing persons) other than Mr. James Stern. Parent, Intermediate and the Company will not be liable under the foregoing indemnification provision to the extent that any loss, claim, damage, liability,
cost or expense is (i) determined by a court, in a final judgment from which no further appeal may be taken, to have resulted primarily from the gross negligence or willful misconduct of Cypress or (ii) in the event Cypress is in breach of
the foregoing representation and warranty. In no event will Cypress or any Indemnified Party be liable to the Company or any of its affiliates for any indirect, special, incidental or consequential damages, including, without limitation, lost
profits or savings, whether or not such damages are foreseeable, or for any third party claims (whether based in contract, tort or otherwise), relating to the services to be provided by Cypress hereunder.

6. Term; Early Termination. This Agreement shall become effective as of the date hereof and
shall terminate on the first to occur of (i) June 30, 2013 (or, if the proviso of Section 3(c) is applicable, such later date as provided therein) or (ii) payment in full of the Success Fee. Parent, Intermediate and the Company
may terminate this Agreement at any time on 90 days prior written notice. Upon such termination by such notice, Cypress shall no longer be entitled to any Quarterly Fee, but shall remain entitled to earn the Success Fee (excluding, for this purpose,
any portion of the Quarterly Fee that was not paid as a result of early termination) until June 30, 2013 (or, if the proviso of Section 3(c) is applicable, such later date as provided therein). The obligation to pay any Success Fee earned
pursuant to Section 3 prior to termination of this Agreement shall survive termination of this Agreement. Sections 4 (solely with respect to expenses incurred prior to the date of termination), 5, 6, 7 and 8 shall survive the termination of
this Agreement.

7. Permissible Activities. Nothing herein shall in any way preclude Cypress or its partners, members,
officers, employees or affiliates from engaging in any business activities or, from performing services or investing in securities of other companies for its or their own account or for the account of others, including for or of companies that may
be in competition with the business conducted by the Company.

8. Confidentiality. Cypress acknowledges that it will receive

any breach by any of Cypress's Representatives of this Section 8. The Information will not, without the prior written consent of the Company, be used by Cypress or its Representatives, directly or indirectly, for any purpose other than the
