The undersigned also understands that RTI intends to enter into a Share Exchange Agreement with Camp Nine, Inc., a Nevada corporation (“Pubco”), pursuant to which Pubco will acquire 100% of the issued and outstanding equity securities of RTI, in exchange for the issuance of shares of common stock, par value $0.001 per share, of Pubco (the “ Pubco Common Stock”), which are to be issued to the shareholders of RTI, constituting approximately 80% of the issued and outstanding Pubco Common Stock after such issuance (the “Share Exchange”). As a result of the Share Exchange, RTI will become the wholly owned subsidiary of Pubco and the former shareholders of RTI will became the controlling shareholders of Pubco.

In furtherance of the foregoing, Pubco and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if RTI notifies the undersigned that it does not intend to proceed with the Share Exchange or if the Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to the closing of the Share Exchange, then the undersigned will be released from the undersigned’s obligations under this Lock-Up Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.
