Dear Gary and Jerry:

As you know, we submitted the enclosed claim letter to Corporate Stock Transfer (the "Escrow Agent') on September 29, 2014, which letter sets forth the basis of our claims against those 600,000 MusclePharm Corporation ("MSLP") shares currently being held by the Escrow Agent (the "Claim Letter ").  The Claim Letter claims $4,675,928.84 (the "Claimed Amount ") or 372,881 shares (the "Claimed Shares").
In exchange for you conceding that 90,000 shares be released to MSLP, MSLP will withdraw the Claim Letter as it pertains to all matters stated therein, provided however, MSLP will not withdraw that portion of the Claim Letter. Claimed Amount, and/or Claimed Shares that relates in any way to the 580 Garcia Lease, including, without limitation, the lawsuit or any future known or unknown claim s that are not specifically stated in the Claim Letter that do not relate in anyway to 580 Garcia Lease. 1

MSLP will maintain the Claim Letter as it pertains to 580 Garcia Lease and will enforce its right to have $3,036,723.84 wo1th of MSLP's shares maintained in escrow until such time as MSLP and Cocrystal Pharma , Inc. can reach a mutually agreeable arrangement with respect to 580 Gar·cia Lease. We note that any such arrangement would require you to deliver notice and assurances to MSLP that the lawsuit has been dropped, with prejudice, and that the note holder and landlord will no longer seek to evict MSLP so long as MSLP continues to pay its rent on time.
By this letter we would like to propose the following mutually beneficial arrangement, subject to a definitive settlement agreement , to expedite resolution of the Claim Letter:
1 These 90,000 shares are intended to reimburse MSLP for expenses incurred by Cocrystal and paid for by MSLP, which expense and disbursement s MSLP has been indemnified  for.

This letter, and your acceptance of the aforementioned terms are, without waiver of any rights , agreements, understandings, indemnities, claims or causes of action in law or in equity , which may be asserted by MSLP in any court or tribunal , whether known or unknown , which have not specifically been stated in the Claim Notice, provided however, that all claims set forth in the Cl aims Notice pertaining to 580 Garcia Lease or any future known or unknown claims that are not specifically stated in the Cl aim Letter that do not relate in any way to 580 Garcia Lease are expressly reserved.

Pre-Closing Operating Expenses
    MSLP has incurred $207,723.84 in Indemnified Losses related to pre-closing operating expenses. These expenses are outlined in Schedule A to this letter, which is enclosed herewith.

MSLP has or will suffer $3,036,571.30 of Indemnified Losses arising from a lawsuit commenced against sellers titled: 580 Garcia Properties. LLC vs. Biozone Laboratories. Inc. et al. PS 14-0407, Superior Court of California, County of Contra Costa (the '·Lawsuit"). The Lawsuit pertains to a breach of the lease agreement between BZNE and 580 Garcia Properties, LLC (the “Landlord”), which was executed on March 1, 2004 (the '"Lease"). The Lease was assigned to MSLP in violation of its terms.

Article 10(a)(iii) of the APA provides that Sellers agreed to indemnify MSLP for:

any and all Indemnified Losses related to or arising from claim for breach of contract existing on or prior to the Closing Date, and/or which are brought after the Closing Date for acts and omissions by Sellers, which occurred prior to the closing date .

Additionally, MSLP and ("BZNE'') executed a separate indemnity agreement dated January 2, 20 14 (the “Side“) regarding the subject matter of the lawsuit that provided:

BZNE agrees to unconditionally defend. indemnify and hold harmless MSLP and its Affiliates ... from against and in respect of any and all actions and causes of action, suits, claims, controversies, liabilities, damages, costs and reasonable attorney’s fees which the Indemnified Parties may suffer, expend or incur as a consequence of any actions, claims or proceedings brought by… [580 Garcia Properties, LLC] because of or based upon the failure of the parties to obtain Landlord’s consent to the transfer of the Garcia Lease. Such recoverable damages will include payment of all relocation expenses (which MSLP·s management has advised BZNE could exceed $3.0 million) if such relocation is necessary, including payment of moving expenses and any rental amounts at a new facility that are in excess of the rental amounts under the Garcia Lease and incurred during the period of the Garcia Lease would have been in effect.

Based on the terms of the APA and the Side Indemnity, as set forth above, BZNE has indemnified MSLP for the lawsuit and any other damages that may arise .from Lease, including , relocation expenses.

Litigation fees of $36,571 .30 related to the Lawsuit: and

Anticipated Relocation Expenses $3,000,000.

Sellers agreed to indemnify for “·any and all Indemnified Losses arising from or in connection with any breach or violation of the covenants or agreement s of Sellers contained in the [APA]."
