Subject to the fulfillment of all the terms and conditions hereof (unless waived as herein provided), at the Time of Closing: the Seller shall deliver to the Purchaser a certificate or certificates representing all of the issued and outstanding MedElite shares, duly endorsed in blank for transfer, and/or will cause the transfer of such shares to be duly and regularly recorded on the books of MedElite in the name of the Purchaser and/or cause a new certificate issued in the Purchaser’s name to be delivered at the time of Closing or earlier; and the Purchaser shall deliver to the Seller a certificate representing ten million (10,000,000) EFSF shares duly recorded on the books of EFSF in the Seller’s name. The EFSF shares delivered shall be “restricted securities,” as defined in Rule 144(a) of the Securities Act of 1933 and may not be offered or sold without compliance with the registration requirements of that Act of an available exemption from registration.

Dr. Goldfarb may transfer any of the ten million shares to any person (individual or entity), provided the Board of Directors of EFSF consents in writing to such transfer and further provided that the transferee agrees in writing to the terms and conditions of the lock-up.
