If, during the period in which Sangamo is required to deliver the Prospectus in connection with the issuance and sale of the Shares (“Prospectus Delivery Period”), any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Prospectus to comply with the Securities Act, the Company will promptly notify Sigma of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to Sigma, a copy of such amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.
     3.36 SEC Filings. Sangamo will file all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and during the Prospectus Delivery Period.

Representations, Warranties and Covenants of Sigma
     Sigma represents and warrants to, and covenants and agrees with, Sangamo, as of the date hereof and as of the date of Closing, as follows:
     4.1 Due Organization. Sigma is a corporation duly organized under the laws of the State of Delaware, and has all necessary power and authority to conduct its business in the manner in which it is currently being conducted. Sigma is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the ownership or operation of its assets or the conduct of its business requires such qualification, except for failures to be so qualified or in good standing, as the case may be, that would not individually or in the aggregate have a material adverse effect on Sigma.
     4.2 Authority; Binding Nature of Agreement. Sigma has the right, power and authority to enter into and perform its obligations under this Agreement. The execution, delivery and performance of this Agreement by Sigma have been duly authorized by all necessary corporate action on the part of Sigma. Assuming due execution by Sangamo, this Agreement constitutes the legal, valid and binding obligation of Sigma, enforceable against Sigma in accordance with its terms, subject to (a) laws of general application relating to bankruptcy, insolvency and the relief of debtors, and (b) rules of law governing specific performance, injunctive relief and other equitable remedies.
     4.3 Non-Contravention. The execution, delivery and performance of this Agreement by Sigma, and the consummation by Sigma of the transactions contemplated hereby, do not (i) contravene or conflict with the organizational documents Sigma; (ii) constitute a violation of any provision of any federal, state, local or foreign law, rule, regulation, order or decree applicable to Sigma; or (iii) constitute a default or require any consent under, give rise to any right of termination, cancellation or acceleration of, or to a loss of any material benefit to which Sigma is entitled under, or result in the creation or imposition of any lien, claim or encumbrance on any asset of Sigma under, any material contract to which Sigma is a party or any material permit, license or similar right relating to Sigma or by which Sigma may be bound or affected.
     4.4 Short Sale. Neither Sigma nor any person acting on behalf of, or pursuant to any understanding with or based upon any information received from, Sigma has, directly or indirectly, engaged in any transactions in the securities of Sangamo (including, without limitation, any Short Sales involving Sangamo’s securities). “Short Sales” include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, whether or not against the box, and all types of direct and indirect stock pledges, forward sale contracts, options, puts, calls, short sales, swaps, “put equivalent positions” (as defined in Rule 16a-1(h) under the Exchange Act) and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.
     4.5 Lock-Up Period. Beginning on the date hereof and continuing for a period of 180 days, Sigma and its affiliate shall not (i) sell, offer to sell offer, hypothecate, pledge,

12.


 

announce the intention to sell, contract to sell, sell any option or contract to purchase, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, with respect to any Shares or (ii) enter into any swap, hedge or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Shares, without the prior written consent of Sangamo (which consent may be withheld in Sangamo’s sole discretion). Sigma acknowledges that the certificate representing the Shares being purchased hereunder shall contain an appropriate legend regarding the foregoing transfer restriction.
