WERNER (hereinafter collectively referred to as "Thatcher and Werner" and/or the "Indemnifying Party"), whose address is 360 Thames Street, First Floor, Newport, Rhode Island, 02840, and the ESTATE OF THOMAS N. HACKETT (hereinafter referred to as the "Estate" and/or the "Indemnified Party"), whose administrative address is C/O Bryan M. Dench, Esq., Skelton, Taintor & Abbott, 95 Main Street, Auburn, Maine 04212-3200; WITNESSETH Upon execution of the Closing documents and Exhibits attached hereto, the transaction will be completed whereby the sale of One Hundred Fifty-Six Thousand (156,000) shares of Acadia National Health Systems, Inc. (hereinafter referred to as "Acadia") common stock and Seventy-three (73) shares of PRI, Inc. (hereinafter referred to as "PRI") common stock is being purchased from the Estate by several affiliates of the Company (including present officers and directors.) The transaction is hereby consummated with the execution of all documents set forth herein and attached hereto as Exhibits, and involves the estate's beneficial ownership of shares of Acadia and PRI's common stock. The sale is hereby made pursuant to Section 4(2) of the Securities Act of 1933 (the "Act") involving the sale of securities not to be made in any public offering. The Estate acknowledges that, prior to consummation of all transactions represented by these closing documents, it was the majority shareholder of Acadia National Health Systems, Inc. ("Acadia and/or the "Company"). The Estate also acknowledges that it had no interest in continuing to control the Board of Directors of the Company nor to retain the majority ownership of the Company. Thatcher and Werner acknowledge hereby that they will accept appointment to the Board of Directors of Acadia and will also accept appointment by the Interim Board to be officers of the Company. This appointment will automatically assign "affiliate" status to both Thatcher and Werner and will restrict all common equity holdings they have in the Company, pursuant to Rule 144 of the Act and Section 13 or 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act"). In order to provide further assurances to the Estate, and as part of the negotiated sale of the Estate's controlling interest, Thatcher and Werner have agreed to hold harmless and indemnify the Estate against any liability which may arise out of the continued operation, development and expansion of Acadia. NOW THEREFORE, IT IS AGREED AS FOLLOWS: 1. Indemnification: In consideration of the Estate appointing Thatcher and Werner to serve as members of the Board of Directors of Acadia, and to induce the consummation of the purchase and sale of the Estate's controlling interest in Acadia to present officers of the Company, Thatcher and Werner hereby agree to indemnify and hold harmless the Estate against any and all liability, claims or causes of action whatsoever arising out of the continued operation, development and expansion of Acadia, including reasonable attorneys fees and costs incurred in defending any such claims or causes of action; provided, however, that this indemnification shall not apply to any intentional acts committed by the Estate, which are deemed by a court of law to have been fraudulent or in breach of its fiduciary duty to Thatcher and Werner or the officers and directors of the Company. 2. Insurance: Thatcher and Werner will insure the Estate by purchasing an indemnity policy of insurance or bond which may be in the form of specific directors and officers insurance ("D&O"). All policies shall be listed in Schedule A attached hereto, and the policies and any proceeds received thereunder shall be made payable to the Estate for the purposes of this Agreement. Thatcher and Werner shall have the right to take out insurance on the life of any Shareholder whenever, in the opinion of either party, additional insurance may be required to carry out the obligations under this Agreement. Thatcher and Werner shall ensure payment of all premiums on insurance policies taken out pursuant to this Agreement and shall give proof of payment to the Estate within fifteen (15) days after a written request by the Estate or its representative. 3. Warranties/Representations: (i) The Indemnifying Party hereby jointly and severally agrees to indemnify the Estate and defend and hold it harmless from and against all claims, damages, losses, costs, and expenses (including reasonable attorney fees, court costs and other expenses incident to any proceeding, investigation or any claim, including without limitation in any suit by the Estate against the Indemnifying Party) attributable directly or indirectly to the breach by the Indemnifying Party of any obligation hereunder or the inaccuracy of any representation or warranty made by the Indemnifying Party herein or in any instrument delivered pursuant hereto or in connection with the transactions contemplated hereby, including, but not limited to, the Schedule. (ii) A claim for indemnification shall be made only by the Estate notifying the Indemnifying Party of the existence of the claim for which indemnification is sought. The Estate shall thereafter be entitled, at its option, to control, or participate in, any prosecution or defense relating to such claim for indemnity (including without limitation decisions to settle or appeal) through attorneys and agents of its choosing, all at the expense of the Indemnifying Party (except in any suit by the Indemnifying Party against the Estate). The results of any such prosecution or defense shall be binding upon the Indemnifying Party and the Estate for purposes of resolving any claim for indemnity. (iii)Notwithstanding the foregoing, no new notice of claim for indemnity may be given by the Estate after July 1, 2002; any claims for indemnity thereafter are barred. Any claims for indemnity, or portions thereof, in excess of the aggregate amount of proceeds received from the indemnity policy due to the Indemnifying Party and the Estate shall be the joint and several responsibility of the Indemnifying Party and paid to the Estate on demand. The Indemnifying Party shall not be entitled to indemnity or contribution from, or subrogation to or recovery against the Estate with respect to any liability of the Indemnifying Party which may arise under this Agreement of the transactions contemplated hereby. 4. This Agreement shall bind upon and inure to the benefit of the heirs, successors and assigns of the parties hereto.
