7.       Indemnification and Insurance:

                  (a) Right to Indemnification. Each person who was or is made a
         party or is threatened to be made a party or is involved in any action,
         suit or proceeding, whether civil, criminal, administrative or
         investigative (hereinafter a "proceeding"), by reason of





         the fact that he or she, or a person of whom he or she is the legal
         representative, is or was a director or officer, of the Corporation or
         is or was serving at the request of the Corporation as a director,
         officer, employee or agent of another corporation or of a partnership,
         joint venture, trust or other enterprise, including service with
         respect to employee benefit plans, whether the basis of such proceeding
         is alleged action in an official capacity as a director, officer,
         employee or agent, shall be indemnified and held harmless by the
         Corporation to the fullest extent authorized by the Delaware General
         Corporation Law, as the same exists or may hereafter be amended (but,
         in the case of any such amendment, only to the extent that such
         amendment permits the Corporation to provide broader indemnification
         rights than said law permitted the Corporation to provide prior to such
         amendment), against all expense, liability and loss (including
         attorney's fees, judgments, fines, ERISA excise taxes or penalties and
         amounts paid or to be paid in settlement) reasonably incurred or
         suffered by such person in connection therewith and such
         indemnification shall continue as to a person who has ceased to be
         director, officer, employee or agent and shall inure to the benefit of
         his or her heirs, executors and administrators; provided, however,
         that, except as provided in paragraph (b) hereof, the Corporation shall
         indemnify any such person seeking indemnification in connection with a
         proceeding (or part thereof) initiated by such person only if such
         proceeding (or part thereof) was authorized by the Board of Directors
         of the Corporation. The right to indemnification conferred in this
         Section shall be a contract right and shall include the right to be
         paid by the Corporation the expenses incurred in defending any such
         proceeding in advance of its final disposition; provided, however,
         that, if the Delaware General Corporation Law requires, the payment of
         such expenses incurred by a director or officer in his or her capacity
         as a director or officer (and not in any other capacity in which
         service was or is rendered by such person while a director or officer,
         including, without limitation, service to an employee benefit plan) in
         advance of the final disposition of a proceeding, shall be made only
         upon delivery to the Corporation of an undertaking, by or on behalf of
         such director or officer, to repay all amounts so advanced if it shall
         ultimately be determined that such director or officer is not entitled
         to be indemnified under this Section or otherwise. The Corporation may,
         by action of its Board of Directors, provide indemnification to
         employees and agents of the Corporation with the same scope and effect
         as the foregoing indemnification of directors and officers.

                  (b) Right of Claimant to Bring Suit: If a claim under
         paragraph (a) of this Section is not paid in full by the Corporation
         within thirty (30) days after a written claim has been received by the
         Corporation, the claimant may at any time thereafter bring suit against
         the Corporation to recover the unpaid amount of the claim and, if
         successful in whole or in part, the claimant shall be entitled to be
         paid also the expense of prosecuting such claim. It shall be a defense
         to any such action (other than an action brought to enforce a claim for
         expenses incurred in defending any proceeding in advance of its final
         disposition where the required undertaking, if any is required, has
         been tendered to the Corporation) that the claimant has not met the
         standards of conduct which make it permissible under the Delaware
         General Corporation Law for the Corporation to indemnify the claimant
         for the amount claimed, but the burden of proving such defense



                                      -2-


         shall be on the Corporation. Neither the failure of the Corporation
         (including its Board of Directors, independent legal counsel, or its
         stockholders) to have made a determination prior to the commencement of
         such action that indemnification of the claimant is proper in the
         circumstances because he or she has met the applicable standard of
         conduct set forth in the Delaware General Corporation Law, nor an
         actual determination by the Corporation (including its Board of
         Directors, independent legal counsel, or its stockholders) that the
         claimant has not met such applicable standard or conduct, shall be a
         defense to the action or create a presumption that the claimant has not
         met the applicable standard of conduct.

                  (c) Notwithstanding any limitation to the contrary contained
         in subparagraphs 7(a) and 7(b), the Corporation shall to the fullest
         extent permitted by Section 145 of the General Corporation Law of the
         State of Delaware, as the same may be amended and supplemented,
         indemnify any and all persons whom it shall have power to indemnify
         under said section from and against any and all of the expenses,
         liabilities or other matters referred to in or covered by said section,
         and the indemnification provided for herein shall not be deemed
         exclusive of any other rights to which those indemnified may be
         entitled under any By-Law or agreement, vote of stockholders or
         disinterested Directors or otherwise, both as to action in his official
         capacity and as to action in another capacity while holding such
         office, and shall continue as to a person who has ceased to be
         director, officer, employee or agent and shall inure to the benefit of
         the heirs, executors and administrators of such a person.

                  (d) Insurance. The Corporation may maintain insurance, at its
         expense, to protect itself and any director, officer, employee or agent
         of the Corporation or another corporation, partnership, joint venture,
         trust or other enterprise against any such expense, liability or loss,
         whether or not the Corporation would have the power to indemnify such
         person against such expense, liability or loss under Delaware General
         Corporation Law.

8.       A director of the Corporation shall not be personally liable to the
         Corporation or its stockholders for monetary damages for breach of
         fiduciary duty as a director for any act or omission; provided,
         however, that the foregoing shall not eliminate or limit the liability
         of a director (a) for any breach of the director's duty or loyalty to
         the Corporation or its stockholders, (b) for any act or omission not in
         good faith or which involves intentional misconduct or a knowing
         violation of law, (c) under Section 174 of the General Corporation Law
         of the State of Delaware, or (d) for any transaction from which the
         director derived an improper personal benefit. Any repeal or
         modification of this article by the stockholders of the Corporation
         shall be prospective only, and shall not adversely affect any
         limitation on the personal liability of a director of the Corporation
         existing at the time of such repeal or modification.


9.       In furtherance and not in limitation of the powers conferred by the
         General Corporation Law of the State of Delaware, the Board of
         Directors of the Corporation is expressly authorized to make, alter, or
         repeal the By-Laws of the Corporation.



                                      -3-


10.      Elections of directors need not be by written ballot except and to the
         extent provided in the By-Laws of the corporation.


         I, Paula S. Belcher, being the Sole Incorporator hereinbefore named,
for the purpose of forming a corporation pursuant to the General Corporation Law
of the State of Delaware, do make this certificate, hereby declaring and
certifying and this is my act and deed and the facts herein stated are true, and
accordingly have hereunto set my hand this 17th day of March, 1999.
