The Nance Financial Statements, true and complete copies of which have been previously delivered to St. Mary present fairly the financial position, assets and liabilities of Nance as of the dates thereof and the revenues, expenses, results of operations and cash flows of Nance for the periods covered thereby, on a tax basis with adjustments made in accordance with GAAP so that the net asset value of Nance can be determined and reasonably compared with the net asset value of St. Mary. The Nance Financial Statements are in accordance with the books and records of Nance and do not reflect any transactions which are not bona fide transactions. The books and records of Nance have been maintained in accordance with applicable laws, rules and regulations, and in the ordinary course of business. To the best of Stockholders' Knowledge, the accounts and notes receivable of Nance reflected in the Nance Financial Statements are valid, existing and genuine and represent sales actually made or services actually delivered by Nance in bona fide transactions in the ordinary course of business consistent with past practice and there is no material right of setoff or counterclaim or threat thereof that would jeopardize the collectability of such accounts and notes receivable at the aggregate recorded amounts thereof.

The Stockholders and St. Mary shall give prompt written notice to each other of any claim by any party which might give rise to a claim by the Stockholders or St. Mary against the other based upon the indemnity provisions contained herein, stating the nature and basis of the claim and the actual or estimated amount thereof; provided, however, that failure to give such notice will not affect the obligation of the indemnifying party to provide indemnification in accordance with the provisions of this Article 7 unless, and only to the extent that, such indemnifying party is actually prejudiced thereby. In the event that any action, suit or proceeding is brought by a third party against the Stockholders or St. Mary with respect to which the other party may have liability under the indemnification provisions contained herein, the indemnifying party shall have the right, at its sole cost and expense, to defend such action in the name or on behalf of the indemnified party and, in connection with any such action, suit or proceeding, the parties hereto agree to render to each other such assistance as may reasonably be required in order to ensure the proper and adequate defense of any such action, suit or proceeding; provided further, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate because of actual or potential differing interests between such indemnified party and any other party represented by such counsel. Neither party hereto shall make any settlement of any claim which might give rise to liability of the other party under the indemnification provisions contained herein without the written consent of such other party, which consent such other party covenants shall not be unreasonably withheld. 30 7.05 Limitation of Liability. Notwithstanding the provisions of this Article 7, neither the Stockholders collectively nor St. Mary shall have any liability to the other with respect to any matter which liability does not exceed $150,000 as to any single liability or $250,000 as to liabilities in the aggregate irrespective of their single size except that such limitations shall not apply to any Third Party Claim. In the event of any liability of the Stockholders for indemnification, St. Mary may elect to cause such liability to be satisfied in part or in whole by reducing pro rata the St. Mary Stock issued to the Stockholders by the number of shares (rounded to the nearest whole number) equal to the amount of the Stockholders' liability based on the published closing price for a share of St. Mary Stock on the day such liability is quantified, and the certificates of St. Mary Stock issued to the Stockholders shall bear a legend to that effect. ARTICLE 8 SHARE RESTRICTIONS 8.01 Restricted Shares. The Stockholders hereby agree that during the period beginning on the Closing and, subject to Section 8.05, ending on the date which is three years after the date hereof, the Stockholders will not sell, assign, transfer, pledge, hypothecate, encumber or otherwise dispose of ("Transfer") any shares of St. Mary Stock received as part of the Consideration (the "Restricted Shares"), other than in accordance with the terms of this Article 8 or as otherwise agreed by St. Mary in writing in its sole discretion, and any such purported Transfer shall be void, except that the Stockholders may make a Permitted Transfer (as hereinafter defined), if and only if the transferee in such Permitted Transfer ("Permitted Transferee") executes and delivers a written agreement to the effect that the Restricted Shares transferred to such Permitted Transferee shall be bound by the terms of this Article 8 as if such Permitted Transferee were an original party hereto. 8.02 Permitted Transfer. For purposes of this Article 8, a "Permitted Transfer" of Restricted Shares by any Stockholder is (i) any bona fide gift of such Restricted Shares by the Stockholder, including a charitable gift, (ii) any transfer of such Restricted Shares by the Stockholder to a trustee for the benefit of the Stockholder or the Stockholder's ancestors, descendants or spouse, or (iii) any transfer of such Restricted Shares by a Stockholder to the Stockholder's executors, administrators or legal representatives, heirs or devisees pursuant to the laws of descent and distribution. 8.03 Restrictive Legends; Stop Orders. The certificate or certificates representing Restricted Shares issued to the Stockholders or any Permitted Transferee shall bear an appropriate legend referring to the restrictions on Transfer contained in this Article 8 (together with the legends referred to in 31 Section 3.29 and Section 7.05 hereof) shall be endorsed with substantially the following legend in addition to any other legend which may appear on such certificate or certificates: THE SALE, ASSIGNMENT, TRANSFER, PLEDGE, HYPOTECATION, ENCUMBRANCE OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A STOCK EXCHANGE AGREEMENT DATED JUNE 1, 1999, BETWEEN ST.

Any provision of this Agreement to the contrary notwithstanding, the restrictions on Transfer contained in this Article 8 shall expire as follows: (i) with respect to twenty percent of the original number of Restricted Shares, one year after the date hereof, and (ii) with respect to the remaining Restricted Shares, three years after the date hereof. The restrictions contained herein shall expire with respect to the Restricted Shares held by the Stockholders in proportion to his respective ownership of shares of St. Mary Stock on the date hereof. 8.05 Removal of Legends. Whenever the restrictions imposed by this Article 8 shall terminate by reason of the passage of time and the Restricted Shares are transferable pursuant to Rule 144(k) under the Securities Act or other available exemption from the registration requirements of the Securities Act, each holder of Restricted Shares shall be entitled to receive from St. Mary, without cost or expense, a new certificate representing such Restricted Shares not bearing the legends set forth in Section 8.03 and Section 3.29 upon receipt of an opinion of counsel reasonably satisfactory to St. Mary that such restrictions have terminated in accordance with their terms and that such Restricted Shares are transferable without registration under the Securities Act pursuant to Rule 144(k) under the Securities Act or other available exemption from the registration requirements of the Securities Act. 32 8.06 Voting Rights. The holder or holders of Restricted Shares shall retain the full right to vote or to execute and deliver a proxy to vote Restricted Shares on any matter submitted to holders of St. Mary Stock.
