This Agreement is made with reference to the following facts and circumstances:

A.                                   Seller is a physician licensed in the State of California and the record owner of eight hundred thirty-nine and 02/100 (839.02) shares (the “Shares”) of common stock of Company, representing approximately fifty five percent (55%) of the issued and outstanding shares of Nuestra Familia Medical Group, Inc.

B.                                     Purchaser is a physician licensed in the State of California.

C.                                     PMG was the holder of an option to buy the Shares.

D.                                    PMS is the manager of PMG pursuant to a long term management agreement and is a party to an agreement of accommodation reflecting that option to buy the Shares then held by PMG, was held by PMG as an accommodation on behalf of PMS. .

D.                                    PMG assigned the option to Purchaser, with the consent of PMS, so that Purchaser, as a duly licensed physician, could serve as the nominee holder of record title to PMG’s shares in Nuestra.

E.                                      Purchaser exercised the option to purchase the Shares and desires to effectuate the transfer of the Shares pursuant to this Agreement.

F.                                      As a result of Purchaser’s purchase of the Shares, Purchaser will hold all of PMG’s shares in Nuestra which equals approximately 55% of Nuestra’s issued and outstanding shares.

G.                                     Seller desires to sell the Shares to Purchaser and Purchaser desires to purchase the Shares from Seller, on the terms and conditions set forth in this Agreement.
