II-1 (a) The Restated Articles of Incorporation of the registrant provide for indemnification as follows: "TWELFTH: 1. The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, except an action by or in the right of the corporation, by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with the action, suit or proceeding if he acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, has no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, does not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and that, with respect to any criminal action or proceeding, he had reasonable cause to believe that his conduct was unlawful. 2. The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses, including amounts paid in settlement and attorneys' fees actually and reasonably incurred by him in connection with the defense or settlement of the action or suit if he acted in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation. Indemnification shall not be made for any claim, issue or matter as to which such a person has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable to the corporation or for amounts paid in settlement to the corporation unless and only to the extent that the court in which the action or suit was brought or other court of competent jurisdiction determines upon application that in II-2 view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. 3. To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in sections 1 and 2 of this Article Twelfth, or in defense of any claim, issue or matter therein, he must be indemnified by the corporation against expenses, including attorneys' fees, actually and reasonably incurred by him in connection with the defense. 4. Any indemnification under sections 1 and 2 of this Article Twelfth, unless ordered by a court or advanced pursuant to section 5 of this Article Twelfth, must be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances. The determination must be made: (a) By the stockholders; (b) By the board of directors by majority vote of a quorum consisting of directors who were not parties to the act, suit or proceeding; (c) If a majority vote of a quorum consisting of directors who were not parties to the act, suit or proceeding so orders, by independent legal counsel in a written opinion; or (d) If a quorum consisting of directors who were not parties to the act, suit or proceeding cannot be obtained, by independent legal counsel in a written opinion. 5. The expenses of officers and directors incurred in defending a civil or criminal action, suit or proceeding must be paid by the corporation as they are incurred and in advance of the final disposition of the action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay the amount if it is ultimately determined by a court of competent jurisdiction that he is not entitled to be indemnified by the corporation. The provisions of this section 5 of this Article Twelfth do not affect any rights to advancement of expenses to which corporate personnel other than directors or officers may be entitled under any contract or otherwise by law. II-3 6. The indemnification and advancement of expenses provided by this Article Twelfth: (a) Does not exclude any other rights to which a person seeking indemnification or advancement of expenses may be entitled under these articles of incorporation or any bylaws, agreement, vote of stockholders or disinterested directors or otherwise, for either an action in his official capacity or an action in another capacity while holding his office, except that indemnification, unless ordered by a court pursuant to section 2 of this Article Twelfth or for the advancement of expenses of any director or officer, if a final adjudication establishes that his acts or omissions involved intentional misconduct, fraud or a knowing violation of the law and was material to the cause of action. (b) Continues for a person who has ceased to be a director, officer, employee or agent and inures to the benefit of the heirs, executors and administrators of such a person. 7. The corporation may purchase and maintain insurance or make other financial arrangements on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise for any liability asserted against him and liability and expenses incurred by him in his capacity as a director, officer, employee or agent, or arising out of his status as such, whether or not the corporation has the authority to indemnify him against such liability and expenses. 8. The other financial arrangements made by the corporation pursuant to section 7 of this Article Twelfth may include the following: (a) The creation of a trust fund. (b) The establishment of a program of self-insurance. (c) The securing of its obligation of indemnification by granting a security interest or other lien on any assets of the corporation. (d) The establishment of a letter of credit, guaranty or surety. II-4 No financial arrangement made pursuant to this section may provide protection for a person adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable for intentional misconduct, fraud or a knowing violation of law, except with respect to the advancement of expenses or indemnification ordered by a court. 9. Any insurance or other financial arrangement made on behalf of a person pursuant to this Article Twelfth may he provided by the corporation or any other person approved by the board of directors, even if all or part of the other person's stock or other securities is owned by the corporation. 10. In the absence of fraud: (a) The decision of the board of directors as to the propriety of the terms and conditions of any insurance or other financial arrangement made pursuant to this Article Twelfth and the choice of the person to provide the insurance or other financial arrangement shall be conclusive; and (b) The insurance or other financial arrangement: (1) Is not void or voidable; and (2) Does not subject any director approving it to personal liability for his action, even if a director approving the insurance or other financial arrangement is a beneficiary of the insurance or other financial arrangement." (b) The registrant's Bylaws provide that the registrant shall indemnify each and every present and former director and officer of the registrant, and each and every person who may have served at the registrant's request as a director or officer of another corporation in which the registrant owns shares of capital stock or of which the registrant is a creditor (each of which other corporation is individually referred to herein as an "Other Enterprise"), against any and all expenses (including attorneys' fees) actually and necessarily incurred by him in connection with the defense of any action, suit or proceeding in which he was or is a party by reason of being or having been a director or officer of the registrant or Other Enterprise to the fullest extent permitted by law. The rights of indemnification provided in the Bylaws are in addition to any other rights to which a person may otherwise be entitled by any other provisions of the registrant's Restated Articles of Incorporation, statute, agreement, vote of stockholders or otherwise. II-5 The registrant's Bylaws further provide that the registrant shall indemnify officers and directors of the registrant, as well as other persons who serve as agents and employees of the registrant, to the extent set forth in the Restated Articles. Additionally, the registrant's Bylaws provide that the registrant may purchase and maintain insurance on behalf of, and contractually agree to indemnify, any person who is or was a director, officer, employee or agent of the registrant, or is or was serving at the request of the registrant as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the registrant would have the power to indemnify him against such liability under the provisions of the Bylaws. (c) The registrant has entered into agreements with each Director, certain key employees, including Brian K. Harrington and G. Stephen Holcomb, and certain directors of subsidiaries of the registrant, that provide for the indemnification of such individuals for certain liabilities incurred in such capacity. Item 8. Exhibits.

Item 9. Undertakings. A. The undersigned registrant hereby undertakes: (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; (2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such II-7 securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. B. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. C. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Section 4. Conditions for Grant of Options. (a) Each Option shall be evidenced by an option agreement that may contain any term deemed necessary or desirable by the Committee, provided such terms are not inconsistent with this Plan or any applicable law.

The Committee may from time to time in granting Options under the Plan prescribe such other terms and conditions concerning such Options as it deems appropriate, including, without limitation, relating an Option to achievement of specific goals established by the Committee or the continued employment of the Optionee for a specified period of time, provided that such terms and conditions are not more favorable to an Optionee than those expressly permitted herein.

Section 6. Exercise of Options. An Option shall be deemed exercised when (i) the Company has received written notice of such exercise in accordance with the terms of the Option, (ii) full payment of the aggregate exercise price of the Shares as to which the Option is exercised has been made, and (iii) arrangements that are satisfactory to the Committee in its sole discretion have been made for the Optionee's payment to the Company of the amount, if any, that the Committee determines to be necessary for the Company or Subsidiary employing the Optionee to withhold in accordance with applicable federal or state income tax withholding requirements. Unless further limited by the Committee in any Option, the Exercise price of any Shares purchased shall be paid solely in cash, by certified or cashier's check, by money order, with Shares (but with Shares only if permitted by an Option agreement or otherwise permitted by the Committee in its sole discretion at the time of exercise) or by a combination of the above; provided, however, that the Committee in its sole discretion may accept a personal check in full or partial payment of any Shares.

Exercisability of Options. (a) Any Option shall become exercisable in such amounts and at such intervals as the Committee shall provide in any Option, except as otherwise provided in this Section 7; provided in each case that the Option has not expired on the date of exercise. (b) The expiration date of an Option shall be determined by the Committee at the Date of Grant, but in no event shall an Option be exercisable after the expiration of ten (10) years from the Date of Grant. (c) An Option shall not be exercisable prior to the six- month anniversary of its Date of Grant. (d) The Committee may in its sole discretion accelerate the date on which any Option may be exercised. (e) On the date thirty (30) days prior to any occurrence described in Subsections (7)(e)(i), (ii) or (iii), but only where such anticipated occurrence actually takes place, notwithstanding the exercise schedule in an Option, each Option shall immediately become exercisable in full where there (i) is any transaction (which shall include a series of transactions occurring within 60 days or occurring pursuant to a plan) that has the result that shareholders of the Company immediately before such transaction cease to own at least 51% of (x) the voting stock of the Company or (y) of any entity that results from the participation of the Company in a reorganization, consolidation, merger, liquidation or any other form of corporate transaction; (ii) is a merger, consolidation, reorganization, liquidation or dissolution in which the Company does not survive; (iii) is a sale, lease, exchange or other disposition of all or substantially all the property and assets of the Company. (f) Notwithstanding any provisions hereof to the contrary, if any Option is accelerated under Subsection 7(d) or (e), the portion of such Option that may be exercised to acquire Shares that the Optionee would not be entitled to acquire but for such acceleration (the "Acceleration Shares"), is limited to that number of Acceleration Shares that can be acquired without causing the Optionee to have an "excess parachute payment" as determined under Section 280G of the Internal Revenue Code, determined by taking into account all of the Optionee's "parachute payments" determined under Section 280G of the Code.

If any Optionee exercises an Option prior to Stockholder approval of this Plan as provided in Section 19 hereof, the Optionee must tender the exercise price at the time of exercise and the Company shall hold the exercise price and the Shares to be issued pursuant to such exercise until the stockholders approve the Plan.

Any Common Stock delivered in satisfaction of all or a portion of the exercise price shall be appropriately endorsed for transfer and assignment to the Company.

(a) If at any time there shall be an increase or decrease in the number of issued and outstanding Shares, through the declaration of a stock dividend or through any recapitalization resulting in a stock split-up, combination or exchange of Shares, then appropriate proportional adjustment shall be made in the number of Shares (and with respect to outstanding Options, the exercise price per Share): (i) subject to outstanding Options; (ii) reserved under the Plan; and (iii) subject to Options granted subsequently. In the event of a dispute concerning such adjustment, the Committee has full discretion to determine the resolution of such dispute. Such determination shall be final, binding and conclusive. (b) In the event of a merger, consolidation or other reorganization of the Company under the terms of which the Company is not the surviving corporation, but the surviving corporation elects to assume an Option, the respective Agreement and this Plan, the Optionee shall be entitled to receive, upon the exercise of such Option, with respect to each Share issuable upon exercise of such Option, the number of shares of stock of the surviving corporation (or equity interest in any other entity) and any other notes, evidences of indebtedness or other property that Optionee would have received in connection with such merger, consolidation or other reorganization had he exercised the Option with respect to such Share immediately prior to such merger, consolidation or other reorganization.

(d) Without limiting the generality of the foregoing, the existence of outstanding Options granted under the Plan shall not affect in any manner the right or power of the Company to make, authorize or consummate: (i) any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or its business; (ii) any merger or consolidation of the Company; (iii) any issuance by the Company of debt securities or preferred or preference stock that would rank above the Shares subject to outstanding Options; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or assignment of all or any part of the assets or business of the Company; or (vi) any other corporate act or proceeding, whether of a similar character or otherwise.

(b) Notwithstanding the foregoing, the Option shall vest as to all Shares then subject to this Option upon the occurrence of any of the following events: (1) a transaction (or series of transactions occurring within a 60-day period or pursuant to a plan approved by the Board or the shareholders of the Company) occurs which has the result that stockholders of the Company immediately before such transaction cease to own directly or indirectly at least 51% of the voting stock of the Company or of any entity which results from the participation of the Company, in a reorganization, consolidation, merger, liquidation or any other form of corporate transaction; (2) all or substantially all of the assets of the Company shall be sold or otherwise disposed of except that this Option shall not vest as to all Shares then subject to this Option if after such sale or disposition (i) the stockholders of the Company immediately prior to such transaction continue to own at least 51% of the voting stock of the entities which acquired 50% or more in value of the assets of the Company so sold or conveyed and (ii) the acquiring entity agrees to assume the obligations of the Company under this Agreement; or (3) the occurrence of a merger, consolidation or other reorganization of the Company under the terms of which the surviving entity does not assume the obligations of the Company under this Agreement. Section 7. Type of Option. The Option granted hereunder shall be a Nonqualified Stock Option. Section 8. Exercise of the Option. (a) This Option shall not be exercisable prior to January 20, 1994. After January 20, 1994, this Option may be exercised at any time and from time to time during the Option Period, in whole or in part, with respect to Shares that have vested in accordance with Section 6 hereof. If the Optionee exercises this Option prior to stockholder approval of this Plan as provided in Section 4 hereof, the Optionee must tender the exercise price at the time of exercise and the Company shall hold the exercise price and the Shares to be issued pursuant to such exercise until the stockholders approve the Plan. If the Plan is approved by the stockholders, the Company shall issue and deliver the Shares as to which the Option has been exercised. If the Plan is not approved by the stockholders, the Company shall return the exercise price to the Optionee and no Shares will be issued. (b) This Option may be exercised (i) during the Optionee's lifetime, solely by the Optionee or (ii) after the Optionee's death, by the personal representative of the Optionee's estate or the person or persons entitled thereto under his will or under the laws of descent and distribution. (c) This Option shall be deemed exercised when (i) the Company has received written notice of such exercise delivered to the Company in accordance with the terms of Subsection 17(l) hereof, (ii) full payment of the aggregate exercise price of the Shares as to which the Option is exercised has been tendered to the Company, and (iii) arrangements that are satisfactory to the Committee in its sole discretion have been made for the Optionee's payment to the Company of the amount, if any, that the Company determines to be necessary for the Company to withhold in accordance with applicable federal or state income tax withholding requirements. (d) The exercise price of any Shares purchased shall be paid (i) solely in cash, by certified or cashier's check, by money order or by personal check or (ii) at the option of the Optionee, in Common Stock theretofore owned by such Optionee (or by a combination of the above); provided, however, that if the Optionee acquired such stock to be surrendered directly or indirectly from the Company, he shall have owned such stock for six months prior to using such stock to exercise this Option. For purposes of determining the amount, if any, of the exercise price satisfied by payment in Common Stock, such Common Stock shall be valued at its Fair Market Value on the date of exercise. Any Common Stock delivered in satisfaction of all or a portion of the exercise price shall be appropriately endorsed for transfer and assignment to the Company. (e) The Optionee shall not be, nor have any of the rights or privileges of, a stockholder of the Company with respect to any Shares purchasable upon the exercise of any part of this Option unless and until certificates representing such Shares shall have been issued by the Company to the Optionee. Section 9. Termination of Option Period. (a) The unexercised portion of this Option shall automatically and without notice terminate and become null and void upon the earliest to occur of the following: (i) one (1) year after the death of the Optionee; or (ii) July 20, 2003. (b) The Committee in its sole discretion may, by giving written notice to the Optionee ("Cancellation Notice"), cancel, effective upon the date of the consummation of any corporate transaction described in Subsection 6(b) hereof, any portion of this Option which remains unexercised on such date. Such cancellation notice shall be given to Optionee at least ten (10) days prior to the date of cancellation. Section 10. Assignability. This Option is not assignable or otherwise transferable except by will or the laws of descent and distribution. Section 11. Adjustments. (a) If at any time while any unexercised portion of this Option is outstanding there shall be an increase or decrease in the number of issued and outstanding Shares through the declaration of a stock dividend or through any recapitalization resulting in a stock split-up, combination or exchange of Shares, then appropriate adjustment shall be made in the number of Shares II-63 and the exercise price per Share subject to such outstanding portion of this Option, so that the same proportion of the Company's issued and outstanding Shares shall remain subject to purchase at the same aggregate exercise price. (b) In the event of a merger, consolidation or other reorganization of the Company under the terms of which the Company is not the surviving corporation, but the surviving corporation elects to assume this Option, the Optionee shall be entitled to receive, upon the exercise of this Option, with respect to each Share (i) the number of shares of stock of the surviving corporation (or equity interest in any other entity) and (ii) any other notes, evidences of indebtedness or other property, that Optionee would have received in connection with such merger, consolidation or other reorganization had he executed the Option with respect to such Share immediately prior to such merger, consolidation or other reorganization. (c) Except as otherwise expressly provided herein, the issuance by the Company of shares of its capital stock of any class, or securities convertible into shares of capital stock of any class, either in connection with direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of or exercise price of Shares then subject to this Option. (d) Without limiting the generality of the foregoing, the existence of this Option shall not affect in any manner the right or power of the Company to make, authorize or consummate (i) any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or its business; (ii) any merger or consolidation of the Company; (iii) any issue by the Company of debt securities, or preferred or preference stock that would rank above the Shares subject to this Option; (iv) the dissolution or liquidation of the Company; (v) any sale, transfer or assignment of all or any part of the assets or business of the Company; or (vi) any other corporate act or proceeding, whether of a similar character or otherwise. Section 12. Purchase for Investment. As a condition of any issuance of a stock certificate for Shares, the Committee may obtain such agreements or undertakings, if any, as it may deem necessary or advisable to assure compliance with any provision of this Option or any law or regulation, including, but not limited to, the following: (a) a representation and warranty by the Optionee to the Company, at the time this Option is exercised, that he is acquiring the Shares to be issued to him for investment and not with a view to, or for sale in connection with, the distribution of any such Shares; and (b) a representation, warranty or agreement to be bound by any legends that are, in the opinion of the Committee, necessary or appropriate to comply with the provisions of any securities law deemed by the Committee to be applicable to the issuance of the Shares and are endorsed upon the certificates representing the Shares. Section 13. Amendment, Modification, Suspension or Discontinuance of this Plan. For the purpose of complying with changes in the Code or ERISA, the Committee may amend, modify, suspend or terminate the Option any time without the consent of the Optionee and for the purpose of meeting or addressing any other changes in legal requirements or any other purpose, the Committee may amend, modify, suspend or terminate the Option only once every six months; provided that no such amendment, modification, suspension or termination shall materially impair the Option without the consent of the Optionee. Section 14. Government Regulations. This Option, and the obligation of the Company to sell and deliver Shares under this Option, shall be subject to all applicable laws, rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. Section 15. Withholding. Prior to the issuance of any Shares to Optionee under this Option, Optionee shall pay to the Company in a form satisfactory to the Company the amount (if any) which the Company reasonably determines to be necessary for the employer of the Optionee to withhold in accordance with applicable federal or state tax withholding requirements. Section 16. Administration of the Plan. (a) This Option shall be administered by the Committee. The Committee shall be the Compensation Committee of the Board excluding Optionee (if he is a member of the Compensation Committee); provided, however, that for purposes of this Option, the Committee shall consist of not less than two individuals; provided further, however, that if no Compensation Committee is appointed, the Board (if a majority of which and a majority of the Directors acting on any matter are Disinterested Persons) shall administer the Option and in such case all references to the Committee shall be deemed to be references to the Board. The Committee shall have all of the powers of the Board with respect to the Option. (b) The Committee, from time to time, may adopt rules and regulations for carrying out the purposes of the Option. The determinations and the interpretation and construction of any provision of the Option by the Committee shall be final and conclusive. (c) Any and all decisions or determinations of the Committee shall be made either (i) by a majority vote of the members of the Committee at a meeting, or (ii) without a meeting by the written approval of a majority of the members of the Committee. (d) Subject to the express provisions of this Option, the Committee shall have the authority, in its sole and absolute discretion (i) to adopt, amend, and rescind administrative and interpretive rules and regulations relating to this Option; (ii) to construe the terms of this Option; (iii) as provided in Subsection 11, upon certain events to make appropriate adjustments to the exercise price and number of Shares subject to this Option; and (iv) to make all other determinations and perform all other acts necessary or advisable for administering this Option, including the delegation of such ministerial acts and responsibilities as the Committee deems appropriate. The Committee may correct any defect or supply any omission or reconcile any inconsistency in this Option in the manner and to the extent it shall deem expedient to carry it into effect, and it shall be the sole and final judge of such expediency. The Committee shall have full discretion to make all determinations on the matters referred to in this Subsection 16(d), and such determinations shall be final, binding and conclusive. Section 17. Miscellaneous. (a) The proceeds received by the Company from the sale of Shares pursuant to this Option shall be used for general corporate purposes. (b) This Option shall be in addition to regular director's fees paid to the Optionee and stock options granted to the Optionee pursuant to the Company's 1989 Director Stock Option Plan or other stock option plans of the Company or other benefits with respect to Optionee's position with the Company or its Subsidiaries. Nothing contained in this Option shall confer upon the Optionee the right to continue as a director or Chairman of the Board of the Company, or interfere in any way with the rights of the Company to terminate his status as a director or Chairman of the Board. (c) Neither the members of the Board nor any member of the Committee shall be liable for any act, omission, or determination taken or made in good faith with respect to this Option, and members of the Board and the Committee shall, in addition to all II-66 other rights of indemnification and reimbursement, be entitled to indemnification and reimbursement by the Company in respect of any claim, loss, damage, or expense (including attorneys' fees, the costs of settling any suit, provided such settlement is approved by independent legal counsel selected by the Company, and amounts paid in satisfaction of a judgment, except a judgment based on a finding of bad faith) arising from such claim, loss, damage, or expense to the full extent permitted by law and under any directors' and officers' liability or similar insurance coverage that may from time to time be in effect. (d) Any payment of cash or any issuance or transfer of Shares to the Optionee, or to his legal representative, heir, legatee, or distributee, in accordance with the provisions of this Option, shall, to the extent thereof, be in full satisfaction of all claims of such persons under the Plan. The Committee may require any Optionee, legal representative, heir, legatee or distributee as a condition precedent to such payment or issuance or transfer of Shares, to execute a release and receipt for such payment or issuance or transfer of Shares in such form as it shall determine. (e) Neither the Committee nor the Company guarantees Shares from loss or depreciation. (f) All expenses incident to the administration, termination, or protection of this Option, including, but not limited to, legal and accounting fees, shall be paid by the Company; provided, however, the Company may recover any and all damages, fees, expenses and costs arising out of any actions taken by the Company to enforce its rights under this Option.

(j) Any action required of the Company relating to this Option shall be by resolution of its Board, the Committee or by a person authorized to act by resolution of the Board or the Committee. (k) If any provision of this Option is held to be illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining provisions of this Option, but such provision shall be fully severable, and this Option shall be construed and enforced as if the illegal or invalid provision had never been included in this Option. (l) Whenever any notice is required or permitted under this Option, such notice must be in writing and personally delivered or sent by mail or delivery by a nationally recognized courier service. Any notice required or permitted to be delivered under this Option shall be deemed to be delivered on the date on which it is personally delivered, or, if mailed, whether actually received or not, on the third Business Day after it is deposited in the United States mail, certified or registered, postage prepaid, addressed to the person who is to receive it at the address which such person has previously specified by written notice delivered in accordance with this Subsection 17(l) or, if by courier, seventy-two (72) hours after it is sent, addressed as described in this Subsection 17(l).

Stone, Jr. (the "Stone Plan", and together with the 1994 Employee Plan and the 1994 Director Plan, the "Plans"). You have requested the opinion of this firm with respect to certain legal aspects of the proposed offering. In connection therewith, we have examined and relied upon the original, or copies identified to our satisfaction, of (1) the Restated Articles of Incorporation and the Bylaws of the Company, each as amended; (2) minutes and records of the corporate proceedings of the Company with respect to the establishment of each of the Plans and the reservation of 1,125,000 additional shares of Common Stock to be issued upon the exercise of options granted under the Plans (collectively, the "Options") and to which the Registration Statement relates; (3) the Registration Statement and exhibits thereto, including the Plans; and (4) such other documents and instruments as we have deemed necessary for the II-71 expression of the opinions herein contained. In making the foregoing examinations, we have assumed the genuineness of all signatures and the authenticity of all documents submitted to us as originals, and the conformity to original documents of all documents submitted to us as certified or photostatic copies. As to various questions of fact material to this opinion, and as to the content and form of the Restated Articles of Incorporation, the Bylaws, minutes, records, resolutions and other documents or writings of the Company, we have relied, to the extent we deem reasonably appropriate, upon representations or certificates of officers or directors of the Company and upon documents, records and instruments furnished to us by the Company, without independent confirmation or verification of their accuracy. Based upon our examination and consideration of, and reliance on, the documents and other matters described above, and subject to the comments and exceptions noted below, we are of the opinion that the Company presently has available sufficient shares of authorized but unissued shares of Common Stock from which the 1,125,000 shares of Common Stock subject to the exercise of Options may be issued. Furthermore, assuming that (i) the outstanding Options were duly granted, the Options to be granted in the future are duly granted in accordance with the terms of the applicable Plan and the shares of Common Stock to be issued pursuant to the exercise of Options are duly issued in accordance with the terms of the applicable Plan, (ii) the Company maintains an adequate number of authorized but unissued shares and/or treasury shares of Common Stock available for issuance to those persons who exercise Options, and (iii) the consideration for shares of Common Stock issued pursuant to the exercise of Options is actually received by the Company in accordance with the terms of the applicable Plan and exceeds the par value of such shares, then are of the opinion that the shares of Common Stock issued pursuant to the exercise of Options and in accordance with the terms of the applicable Plan, will be duly and validly issued, fully paid and nonassessable. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to references to our firm included in or made a part of the Registration Statement. In giving this consent, we do not admit that we come within the category of person whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Securities and Exchange Commission thereunder.
