NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto agree as follows: 1. Certain Acknowledgments by Affiliate. The Affiliate hereby represents and warrants to East that the Affiliate has carefully read this Agreement and the Merger Agreement and, to the extent the Affiliate felt necessary, has discussed the requirements of this Agreement with the Affiliate's professional advisors who are qualified to advise the Affiliate with regard to such matters. Execution of this Agreement shall not be considered an admission by the Affiliate that he or it is an "affiliate", or as a waiver of any rights the Affiliate may have to object to any claim that the Affiliate is such an "affiliate" on or after the date of this Agreement. 2. Compliance with Rule 145 and the Securities Act. (a) The Affiliate understands and hereby acknowledges that the Affiliate has been advised that (A) the issuance of East Common Stock in connection with the Merger is expected to be effected pursuant to a registration statement on Form S-4 promulgated under the Securities Act of 1933, as amended (the "Securities Act") and the resale of such shares of East Common Stock will be subject to restrictions set forth in Rule 145 under the Securities Act; and (B) Affiliate may be deemed to be an "affiliate" of West as the term "affiliate" is used for purposes of Rule 144 and Rule 145 under the Securities Act. Accordingly, the Affiliate hereby agrees not to sell, transfer or otherwise dispose of any East Common Stock issued to the Affiliate in the Merger, or otherwise acquired by the Affiliate subsequent to the date hereof, unless (i) such sale, transfer or other disposition is made in conformity with the requirements of Rule 145 promulgated under the Securities Act; (ii) such sale, transfer or other disposition is made pursuant to a registration statement declared or ordered effective under the Securities Act, or an appropriate exemption from the registration and prospectus delivery requirements of the Securities Act; (iii) the Affiliate delivers to East a written opinion of legal counsel, reasonably acceptable to East in form and substance, that such sale, transfer or other disposition is otherwise exempt from the registration and prospectus delivery requirements of the Securities Act; or (iv) an authorized representative of the SEC shall have rendered written advice to the Affiliate to the effect that the SEC would take no action, or that the staff of the SEC would not recommend that the SEC take any action, with respect to the proposed disposition if consummated. (b) The Affiliate understands and hereby acknowledges that East will give stop transfer instructions to its transfer agent with respect to any East Common Stock issued to the Affiliate pursuant to the Merger, and there shall be placed on the certificates representing such East Common Stock, or any substitutions therefor, a legend stating in substance: "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), APPLIES AND MAY ONLY BE TRANSFERRED IN CONFORMITY WITH SUCH RULE 145 OR PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT, OR IN ACCORDANCE WITH A WRITTEN OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO THE ISSUER IN FORM AND SUBSTANCE, THAT SUCH TRANSFER IS EXEMPT FROM REGISTRATION UNDER THE ACT OR PURSUANT TO WRITTEN ADVICE FROM AN AUTHORIZED REPRESENTATIVE OF THE SEC TO THE EFFECT THAT THE SEC WOULD TAKE NO ACTION, OR THAT THE STAFF OF THE SEC WOULD NOT RECOMMEND THAT THE SEC TAKE ANY ACTION, WITH RESPECT TO THE PROPOSED TRANSFER IF CONSUMMATED." 2 (c) The Affiliate also understands that unless a sale or transfer is made in conformity with the provisions of Rule 145, or pursuant to an effective registration statement, East reserves the right to place, as applicable, on the certificates issued to the Affiliate's transferee with respect to East Common Stock a legend stating in substance: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE ACT APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE ACT AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT." (d) The legends set forth in paragraphs 2(b) and 2(c) above shall be removed (by delivery of a substitute certificate without such legend), if (i) one year shall have elapsed from the date the undersigned acquired East Common Stock received in the Merger and the provisions of Rule 145(d)(2) are then available to the Affiliate, (ii) two years shall have elapsed from the date the Affiliate acquired the East Common Stock received in the Merger and the provisions of Rule 145(d)(3) are then applicable to the Affiliate or (iii) the Affiliate delivers to East (A) satisfactory written evidence that the Shares have been sold in compliance with Rule 145 (in which case, the substitute certificate shall be issued in the name of the transferee); or (B) an opinion of counsel, in form and substance reasonably satisfactory to East, or written advice from an authorized representative of the SEC to the effect that the restrictions imposed by Rule 144 and Rule 145 under the Securities Act no longer apply to the Affiliate. 3.
