SECTION 2. Special Meetings. Special meetings of the shareholders, for any ---------------- purpose or purposes, may be called by the President or by the Board of Directors, and shall be called by the President at the request of the holders of not less than 10% of the outstanding shares of the Corporation entitled to vote at the meeting.

If the stock transfer books shall be closed for the purpose of determining shareholders entitled to notice of or to vote at a meeting of shareholders, such books shall be closed for at least ten (10) days immediately preceding such meeting.

If the stock transfer books are not closed and no record date is fixed for the determination of shareholders entitled to notice of or to vote at a meeting of shareholders, or shareholders entitled to receive payment of a distribution (other than a distribution involving a purchase or redemption by the Corporation of its own shares) or a share dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the Board of Directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of shareholders. When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this section, such determination shall apply to any adjournment thereof except where the determination has been made through the closing of the stock transfer books and the stated period of closing has expired. 2 SECTION 6. Fixing Record Dates for Consents to Action. Unless a record date ------------------------------------------ shall have previously been fixed or determined pursuant to Section 5 of this Article II, whenever action by shareholders is proposed to be taken by consent in writing without a meeting of shareholders, the Board of Directors may fix a record date for the purpose of determining shareholders entitled to consent to that action, which record date shall not precede, and shall not be more than ten (10) days after, the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date has been fixed by the Board of Directors and the prior action of the Board of Directors is not required by the Texas Business Corporation Act, the record date for determining shareholders entitled to consent to action in writing without a meeting shall be the of first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office, its principal place of business, or an officer or agent of the Corporation having custody of the books in which proceedings of meetings of shareholders are recorded. Delivery shall be by hand or by certified or registered mail, return receipt requested.

Such list shall also be produced and opened at the time and place of the meeting and shall be subject to the inspection by any shareholder during the whole time of the meeting.

At such adjournment meeting at which a quorum shall be present or represented, any business may be transacted that might have been transacted as originally notified. The shareholders present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum. 3 SECTION 9. Proxies. At all meetings of shareholders, a shareholder may vote ------- by proxy executed in writing by the shareholder or by his duly authorized attorney in fact. A telegram, telex, cablegram or similar transmission by the shareholder or his duly authorized attorney in fact, or a photographic, photostatic, facsimile or similar reproduction of a writing executed by the shareholder or his duly authorized attorney in fact shall be treated as an execution in writing for purposes of this section. Such proxy shall be filed with the Secretary of the Corporation before or at the time of the meeting. No proxy shall be valid after 11 months from the date of its execution, unless otherwise provided in the proxy.

Such writing, which may be in counterparts, shall be manually executed if practicable; provided, however, that if circumstances so require, effect shall be given to written consent transmitted by telegraph, telex, telecopy or similar means of visual data transmission. Every written consent shall bear the date of signature of each shareholder who signs the consent.

(c) "Proceeding" means any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative, any appeal in such an action, suit or proceeding, and any inquiry or investigation that could lead to such an action, suit or proceeding. SECTION 2. Indemnification. The Corporation shall indemnify every --------------- Indemnitee against all judgments, penalties (including excise and similar taxes), fines, amounts paid in settlement and reasonable expenses actually incurred by the Indemnitee in connection with any Proceeding in which he was, is or is threatened to be named defendant or respondent, or in which he was or is a witness without being named a defendant or respondent, by reason, in whole or in part, of his serving or having served, or having been nominated or designated to serve, in any of the capacities referred to in Section 1 of this Article, if it is determined in accordance with Section 4 of this Article that the Indemnitee (a) conducted himself in good faith, (b) reasonably believed, in the case of conduct in his Official Capacity, that his conduct was in the Corporation's best interests and, in all other cases, that his conduct was at least not opposed to the Corporation's best interests, and (c) in the case of any criminal proceeding, had no reasonable cause to believe that his conduct was unlawful; provided, however, that in the event that an Indemnitee is found liable to the Corporation or is found liable on the basis that personal benefit was improperly received by the Indemnitee the indemnification (i) is limited to reasonable expenses actually incurred by the Indemnitee in connection with the Proceeding and (ii) shall not be made in respect of any Proceeding in which the Indemnitee shall have been found liable for willful or intentional misconduct in the performance of his duty to the Corporation. Except as provided in the immediately preceding proviso to the first sentence of this Section 2 of this Article, no indemnification shall be made under this Section 2 of this Article in respect of any Proceeding in which such Indemnitee shall have been (x) found liable on the basis that personal benefit was improperly received by him, whether or not the benefit resulted from an action taken in the Indemnitee's Official Capacity, or (y) found liable to the Corporation. The termination of any Proceeding by judgment, order, settlement or conviction, or on a plea of nolo contendere or its equivalent, is not of itself determinative that the Indemnitee did not meet the requirements set forth in clauses (a), (b) or (c) in the first sentence of this Section 2 of this Article. An Indemnitee shall be deemed to have been found liable in respect of any claim, issue or matter only after the Indemnitee shall have been so adjudged by a court of competent jurisdiction after exhaustion of all appeals therefrom.

The indemnification provided herein shall be applicable whether or not negligence or gross negligence of the Indemnitee is alleged or proven. 13 SECTION 3. Successful Defense.

SECTION 4. Determinations. Any indemnification under Section 2 of this -------------- Article (unless ordered by a court of competent jurisdiction) shall be made by the Corporation only upon a determination that indemnification of the Indemnitee is proper in the circumstances because he has met the applicable standard of conduct. Such determination shall be made (a) by the Board of Directors by a majority vote of a quorum consisting of directors who, at the time of such vote, are not named defendants or respondents in the Proceeding, (b) if such a quorum cannot be obtained, then by a majority vote of a committee of the Board of Directors, duly designated to act in the matter by a majority vote of all directors (in which designation directors who are named defendants or respondents in the Proceeding may participate), such committee to consist solely of two (2) or more directors who, at the time of the committee vote, are not named defendants or respondents in the Proceeding, (c) by special legal counsel selected by the Board of Directors or a committee thereof by vote as set forth in clauses (a) or (b) of this Section 4 of this Article or, if the requisite quorum of all of the directors cannot be obtained therefor and such committee cannot be established, by a majority vote of all of the directors (in which directors who are named defendants or respondents in the Proceeding may participate); or (d) by the shareholders in a vote that excludes the shares held by directors that are named defendants or respondents in the Proceeding. Determination as to reasonableness of expenses shall be made in the same manner as the determination that indemnification is permissible, except that if the determination that indemnification is permissible is made by special legal counsel, determination as to reasonableness of expenses must be made in the manner specified in clause (c) of the preceding sentence for the selection of special legal counsel. In the event a determination is made under this Section 4 of this Article that the Indemnitee has met the applicable standard of conduct as to some matters but not as to others, amounts to be indemnified may be reasonably prorated. SECTION 5. Advancement of Expenses. Reasonable expenses (including court ----------------------- costs and attorneys' fees) incurred by an Indemnitee who was or is a witness or was, is or is threatened to be made a named defendant or respondent in a Proceeding shall be paid by the Corporation at reasonable intervals in advance of the final disposition of such Proceeding, and without making the determination specified in Section 4 of this Article, after receipt by the Corporation of (a) a written affirmation by such Indemnitee of his good faith belief that he has met the standard of conduct necessary for indemnification by the Corporation under this Article and (b) a written undertaking by or on behalf of such Indemnitee to repay the amount paid or reimbursed by the Corporation if it shall ultimately be determined that he is not entitled to be indemnified by the Corporation as authorized in this Article. Such written undertaking shall be an unlimited obligation of the Indemnitee but need not be secured and it may be accepted without reference to financial ability to make repayment. Notwithstanding any other provision of this Article, the 14 Corporation may pay or reimburse expenses incurred by an Indemnitee in connection with his appearance as a witness or other participation in a Proceeding at a time when he is not named a defendant or respondent in the Proceeding. SECTION 6. Employee Benefit Plans. For purposes of this Article, the ----------------------- Corporation shall be deemed to have requested an Indemnitee to serve an employee benefit plan whenever the performance by him of his duties to the Corporation also imposes duties on or otherwise involves services by him to the plan or participants or beneficiaries of the plan. Excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall be deemed fines. Action taken or omitted by an Indemnitee with respect to an employee benefit plan in the performance of his duties for a purpose reasonably believed by him to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is not opposed to the best interests of the Corporation. SECTION 7. Other Indemnification and Insurance. The indemnification ----------------------------------- provided by this Article shall (a) not be deemed exclusive of, or to preclude, any other rights to which those seeking indemnification may at any time be entitled under the Corporation's Articles of Incorporation, any law, agreement or vote of shareholders or disinterested directors, or otherwise, or under any policy or policies of insurance purchased and maintained by the Corporation on behalf of any Indemnitee, both as to action in his Official Capacity and as to action in any other capacity, (b) continue as to a person who has ceased to be in the capacity by reason of which he was an Indemnitee with respect to matters arising during the period he was in such capacity, and (c) inure to the benefit of the heirs, executors and administrators of such a person. SECTION 8. Notice. Any indemnification of or advance of expenses to an ------ Indemnitee in accordance with this Article shall be reported in writing to the shareholders of the Corporation with or before the notice or waiver of notice of the next shareholders' meeting or with or before the next submission to shareholders of a consent to action without a meeting and, in any case, within the twelve-month period immediately following the date of the indemnification or advance. SECTION 9. Construction. The indemnification provided by this Article shall ------------ be subject to all valid and applicable laws, including, without limitation, Article 2.02-1 of the TBCA, and, in the event this Article or any of the provisions hereof or the indemnification contemplated hereby are found to be inconsistent with or contrary to any such valid laws, the latter shall be deemed to control and this Article shall be regarded as modified accordingly, and, as so modified, to continue in full force and effect. SECTION 10. Continuing Offer, Reliance, etc. The provisions of this Article -------------------------------- (a) are for the benefit of, and may be enforced by, each Indemnitee of the Corporation, the same as if set forth in their entirety in a written instrument duly executed and delivered by the Corporation and such Indemnitee and (b) constitute a continuing offer to all present and future Indemnitees. The Corporation, by its adoption of these Bylaws, (x) acknowledges and agrees that each Indemnitee 15 of the Corporation has relied upon and will continue to rely upon the provisions of this Article in becoming, and serving in any of the capacities referred to in Section 8.1(a) of this Article, (y) waives reliance upon, and all notices of acceptance of, such provisions by such Indemnitees and (z) acknowledges and agrees that no present or future Indemnitee shall be prejudiced in his right to enforce the provisions of this Article in accordance with their terms by any act or failure to act on the part of the Corporation. SECTION 11. Effect of Amendment. No amendment, modification or repeal of ------------------- this Article or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitees to be indemnified by the Corporation, nor the obligation of the Corporation to indemnify any such Indemnitees, under and in accordance with the provisions of the Article as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted. 16
