WITNESSETH:

WHEREAS, GRMH, TSH and FHA, have entered into that certain Amended and Restated Membership Purchase Agreement dated effective March 29, 2013 (the “ARMPA”);

WHEREAS, one of the material conditions of closing under the ARMPA (as defined therein, herein the “Closing”) is the execution of this Agreement, and

WHEREAS, the Parties now desire to enter into this Agreement.

NOW THEREFORE, for and in consideration of the sum of $10 in hand paid, the above premises, the agreements of the Parties set forth herein below, and other good and valuable consideration, the receipt and sufficiency of which are hereby severally acknowledged, it is agreed as follows:

1. Oliver loans; Conversion to Stock. All indebtedness due by GRMH to Oliver, principal and accrued interest (as evidenced by such promissory notes and with principal and interest set forth on Exhibit “A” attached hereto) shall at Closing be converted based on such outstanding principal and interest to shares of common voting stock of GRMH at forty-five cents (45c) per share as set forth on Exhibit “A”. GRMH shall cause such shares to be issued to Oliver at Closing, such shares shall be unrestricted and freely transferable (except as required by SEC rules) and shall be registered after Closing and as soon as possible by GRMH at its cost by S-1 registration. In addition, after Closing and as soon as possible, all existing shares of stock of Oliver (and his related parties Valiant Investments, LLC and Oliver Company Holdings, LLC) in GRMH owned prior to Closing as further set forth on Exhibit “A” (and any warrants exercisable in connection therewith upon any exercise), shall also be registered by GRMH at its cost by S-1 registration. The above shares of GRMH owned by Oliver and his related parties shall in all events be so registered within two years after Closing. The shares of GRMH issued to FHA at Closing shall not be registered prior to the shares of GRMH owned by Oliver and his related parties being registered without the written consent of Oliver. However, in the event all GRMH shares of Oliver and his related parties and any other person or entity, to be registered cannot be so registered due to SEC legal requirements, GRMH shall apportion the securities registered among the securities holders pro rata according to the total amount of securities entitled to be included therein owned by each holder, and such procedure shall continue until all such shares to be registered are registered. After Closing and without the written consent of Oliver, GRMH shall not grant any other person or entity registration rights with respect to GRMH stock with terms superior to or on par with the registration rights granted to Oliver in this Agreement. GRMH shall take all steps necessary to fulfill the provisions of this paragraph 2. In addition, if GRMH proposes to issue any class of common stock in an offering (registered under the Securities Act), then GRMH shall allow Oliver the opportunity and Oliver shall have the right to register and/or include and sell such number of GRMH shares owned by Oliver (the “Oliver Shares”) in such offering as Oliver may request up to 15% of the total number of previously unregistered shares to be offered by GRMH, on the same terms and conditions as the shares to be offered by GRMH. GRMH shall pay the costs of such offering, including the Oliver Shares that are a part of such offering. The rights above are in addition to the registration rights of Oliver pursuant to this Closing Agreement 2. The reference to Oliver shall include his related entities Valiant Investments, LLC and Oliver Company Holdings, LLC.

2. Payment by Oliver to Arvest; Loan to GRMH. Oliver at Closing shall have made as a condition thereto, an agreed payment to Arvest Bank on the limited guaranties of Oliver (and of Oliver Company Holdings, LLC and the Roy T. Oliver Revocable Trust) for the Arvest Bank debt owed by GRMH and SDC and with Oliver to be released therefrom, such payment to be in the amount of $6,000,000.00 and treated as a loan to GRMH ($351,709.60 of this amount already funded for GRMH April loan payment to Arvest as set forth in Exhibit “A”) and subject to the provisions of paragraph 1 above.
