5. Acquisition of Six Degrees Patent. If the Company, directly or indirectly, acquires sole ownership of the Six Degrees Patent (whether by purchase of all other membership units of Degrees LLC or otherwise), then:

(i) in the event the Company and/or its affiliates sell the Six Degrees Patent to any individual or entity (other than the Company or any of its affiliates) as a discrete, stand alone asset sold separately from other assets or businesses of the Company and/or its affiliates, the Company shall, within thirty (30) days after receiving any cash payment arising from such sale, pay to ▇▇▇▇▇▇▇ an amount of cash equal to the product of (A) 0.80 and (B) (x) the aggregate sales price for the Six Degrees Patent in such sale, minus (y) the Purchase Price, minus (z) the aggregate amount paid or payable by the Company and/or its affiliates to acquire sole ownership of the Six Degrees Patent (other than the Purchase Price);

(ii) in the event the Company and/or its affiliates sell the Six Degrees Patent to any individual or entity (other than the Company or any of its affiliates) with other assets or businesses of the Company and/or its affiliates, otherwise than pursuant to a Change of Control Transaction (as defined below), (A) prior to such sale, the Company and ▇▇▇▇▇▇▇ shall mutually agree on the portion of the aggregate sales price in such sale that is attributable to only the Six Degrees Patent and (B) the Company shall, within thirty (30) days after receiving any cash payment arising from such sale, pay to ▇▇▇▇▇▇▇ an amount of cash equal to the product of (A) 0.80 and (B) (x) the portion of the aggregate sales price in such sale that the Company and ▇▇▇▇▇▇▇ mutually agreed is attributable to only the Six Degrees Patent, minus (y) the Purchase Price, minus (z) the aggregate amount paid or payable by the Company and/or its affiliates to acquire sole ownership of the Six Degrees Patent (other than the Purchase Price); and

The provisions contained in this Section 5 shall terminate and have no further force or effect upon the consummation of a Change of Control Transaction. For purposes of this Agreement, the term “Change of Control Transaction” means the acquisition of the Company (whether by merger or otherwise) or the sale of all or substantially all of the assets of the Company.

6. Further Assurances. Subsequent to the execution and delivery of this Agreement and without any additional consideration, each party hereto, at the written request of the other party hereto, will execute and deliver any further legal instruments, and take all such other actions, which are or may become reasonably necessary or helpful to effectuate the purposes of this Agreement.

-4-

7. Governing Law. This Agreement and the relationship between the parties hereto shall be governed by and construed and enforced in accordance with the laws of the State of California without regard to its principles of conflicts of law.

8. Entire Agreement. This Agreement constitutes and contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersedes any and all prior and contemporaneous negotiations, correspondences, agreements, understandings, duties or obligations between the parties respecting the subject matter hereof.

9. Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by facsimile or by electronic delivery in PDF format shall be sufficient to bind the parties to the terms and conditions of this Agreement.

10. Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto shall use their reasonable best efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

11. Specific Performance. The parties hereto hereby acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that each of the parties hereto, in addition to any other available rights or remedies, shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, and each party hereto hereby expressly waives the defense that a remedy in damages will be adequate.

12. Assignment; Successors. The rights and obligations of ▇▇▇▇▇▇▇ under this Agreement may not be assigned or delegated, in whole or in part, by operation of law or otherwise, without the prior written consent of the Company. Subject to the immediately preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and assigns.
