The undersigned has been advised that the issuance of shares of Pure Common Stock to the undersigned in connection with the Merger has been or will be registered with the Commission under the Act on a Registration Statement on Form S-4. However, the undersigned has also been advised that, since the undersigned may be deemed to have been an affiliate of Atria and the distribution by the undersigned of any Pure Common Stock has not been registered, and is not exempt, under the Act, the undersigned may not sell, transfer or otherwise dispose of Pure Common Stock issued to the undersigned in the Merger unless (i) such sale, transfer or other disposition has been registered under the Act, (ii) such sale, transfer or other disposition is made in conformity with the requirements of Rule 145 promulgated by the Commission under the Act, or (iii) in the opinion of counsel reasonably acceptable to Pure, such sale, transfer or other disposition is otherwise exempt from registration under the Act. 5.

THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED JUNE 6, 1996 BETWEEN THE REGISTERED HOLDER HEREOF AND PURE SOFTWARE INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF PURE." 7. Unless the transfer by the undersigned of its Pure Common Stock has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, Pure reserves the right to put the following legend on the certificates issued any transferee of the undersigned: "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES.

The legends set forth in paragraphs 6 and 7 above shall be removed by delivery of substitute certificates without such legend if the undersigned shall have delivered to Pure a copy of a letter from the staff of the Commission, or an opinion of counsel in form and substance reasonably satisfactory to Pure, to the effect that such legend is not required for purposes of the Act. 9.
