those stockholders entitled to vote for directors. A director shall hold office
until the next annual meeting of 



                                       -2-



stockholders and until his or her successor shall be elected and shall qualify,
subject, however, to such director's prior death, resignation or removal from
office. Except as required by law or the provisions of this Amended and Restated
Certificate of Incorporation, all vacancies on the Board of Directors and
newly-created directorships shall be filled by the Board of Directors. Any

                                   ARTICLE VII

         A.       Indemnification of Officers, Directors, Employees and Agents:
The Corporation shall:

                  1. indemnify, to the fullest extent permitted by the DGCL, 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 (other than an action
         by or in the right of the Corporation) by reason of the fact that such
         person 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 such person in
         connection with such action, suit or proceeding if such person acted in
         good faith and in a manner such person reasonably believed to be in, or
         not opposed to, the best interests of the Corporation, and, with
         respect to any criminal action or proceeding, had no reasonable cause
         to believe such person's 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, shall not, of
         itself, create a presumption that the person did not act in good faith
         and in a manner which such person reasonably believed to be in, or not
         opposed to, the best interests of the Corporation, and, with respect to
         any criminal action or proceeding, had reasonable cause to believe that
         such person's conduct was unlawful; and

                  2. 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 such person 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 



                                       -3-



         corporation, partnership, joint venture, trust or other enterprise
         against expenses (including attorneys' fees) actually and reasonably
         incurred by such person in connection with the defense or settlement
         of such action or suit if such person acted in good faith and in a
         manner such person reasonably believed to be in or not opposed to the
         best interests of the Corporation and except that no indemnification
         shall be made in respect of any claim, issue or matter as to which
         such person shall have been adjudged to be liable to the Corporation
         unless and only to the extent that the Court of Chancery or the court
         in which such action or suit was brought shall determine upon
         application that, despite the adjudication of liability but in view of
         all the circumstances of the case, such person is fairly and
         reasonably entitled to indemnity for such expenses which the Court of
         Chancery or such other court shall deem proper; and

                  3. to the extent that a present or former director or officer
         of the Corporation has been successful on the merits or otherwise in
         defense of any action, suit or proceeding referred to in Article
         VII.A.1. and 2., or in defense of any claim, issue or matter therein,
         indemnify such person against expenses (including attorneys' fees)
         actually and reasonably incurred by such person in connection
         therewith; and

                  4. make any indemnification under Article VII.A.1. and 2.
         (unless ordered by a court) only as authorized in the specific case
         upon a determination that indemnification of the director, officer,
         employee or agent is proper in the circumstances because such person
         has met the applicable standard of conduct set forth in Article
         VII.A.1. and 2. Such determination shall be made, with respect to a
         person who is an officer or director at the time of such determination,
         (1) by the Board of Directors by a majority vote of the directors who
         are not parties to such action, suit or proceeding, even if less than a
         quorum, or (2) by a committee of such directors designated by a
         majority vote of such directors, even if less than a quorum, or (3) if
         there are no such directors, or if such directors so direct, by
         independent legal counsel in a written opinion, or (4) by the
         stockholders of the Corporation; and

                  5. pay expenses (including attorneys' fees) incurred by a
         director or officer in defending a civil or criminal action, suit or
         proceeding in advance of the final disposition of such action, suit or
         proceeding upon receipt of an undertaking by or on behalf of such
         director or officer to repay such amount if it shall ultimately be
         determined that such person is not entitled to be indemnified by the
         Corporation as authorized in this Article VII; such expenses (including
         attorneys' fees) incurred by former directors and officers or other
         employees and agents to be so paid upon such terms and conditions, if
         any, as the Corporation deems appropriate.

                  Notwithstanding anything to the contrary contained in this
         Article VII.A, (i) the Corporation shall not be obligated to pay
         expenses incurred by a director or officer with respect to any
         threatened, pending, or completed claims, suits or actions, whether
         civil, criminal, administrative, investigative or otherwise
         ("Proceedings"), initiated or brought voluntarily by such director or
         officer and not by way of defense (other than Proceedings brought to
         establish or enforce a right to indemnification under the provisions of
         this



                                       -4-



         Article VII, unless a court of competent jurisdiction determines that
         each of the material assertions made by such director or officer in
         such Proceedings were not made in good faith or were frivolous) and
         (ii) the Corporation shall not be obligated to indemnify such director
         or officer for any amount paid in settlement of a Proceeding covered
         hereby without the prior written consent of the Corporation to such
         settlement; and

                  6. not deem the indemnification and advancement of expenses
         provided by, or granted pursuant to, the other subsections of this
         Article VII as exclusive of any other rights to which those seeking
         indemnification or advancement of expenses may be entitled under any
         By-law, agreement, or vote of stockholders or disinterested directors,
         or otherwise, both as to action in such person's official capacity and
         as to action in another capacity while holding such office; and

                  7. have the right, authority and power to purchase and
         maintain insurance 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 against any liability asserted against such person and
         incurred by such person in any such capacity, or arising out of such
         person's status as such, whether or not the Corporation would have the
         power to indemnify such person against such liability under the
         provisions of this Article VII; and

                  8. deem the provisions of this Article VII to be a contract
         between the Corporation and each director, or appropriately designated
         officer, employee or agent who serves in such capacity at any time
         while this Article VII is in effect, and any repeal or modification of
         this Article VII shall not affect any rights or obligations then
         existing with respect to any state of facts then or theretofore
         existing or any action, suit or proceeding theretofore or thereafter
         brought or threatened based in whole or in part upon such state of
         facts. The provisions of this Article VII shall not be deemed to be a
         contract between the Corporation and any directors, officers, employees
         or agents of any other corporation (the "Second Corporation") which
         shall merge into or consolidate with the Corporation when the
         Corporation shall be the surviving or resulting Corporation, and any
         such directors, officers, employees or agents of the Second Corporation
         shall be indemnified to the extent required under the DGCL only at the
         discretion of the Board of Directors of the Corporation; and

                  9. continue the indemnification and advancement of expenses
         provided by, or granted pursuant to, this Article VII, unless otherwise
         provided when authorized or ratified, as to a person who has ceased to
         be a director, officer, employee or agent of the Corporation, and the
         indemnification and advancement of expenses provided by, or granted
         pursuant to, this Article VII shall inure to the benefit of the heirs,
         executors and administrators of such a person.


         B. ELIMINATION OF CERTAIN LIABILITY OF DIRECTORS: No director of the
Corporation shall



                                       -5-



be personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to the Corporation or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL,
as the same exists or hereafter may be amended, or (iv) for any transaction from
which the director derived an improper personal benefit. If the DGCL is amended
to authorize the further elimination or limitation of liability of directors,
then the liability of a director of the Corporation existing at the time of such
elimination or limitation, in addition to the limitation on personal liability
provided herein, shall be limited to the fullest extent permitted by the amended
DGCL. Any repeal or modification of this Article VII 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.


                                  ARTICLE VIII

         A director of the Corporation shall not, in the absence of fraud, be
disqualified by his office from dealing or contracting with the Corporation
either as a vendor, purchaser or otherwise, nor in the absence of fraud shall a
director of the Corporation be liable to account to the Corporation for any
profit realized by him from or through any transaction or contract of the
Corporation by reason of the fact that such director, or any firm of which such
director is a member or any corporation of which such director is an officer,
director or stockholder, was interested in such transaction or contract if such
transaction or contract has been authorized, approved or ratified in a manner
provided in the DGCL for authorization, approval or ratification of transactions
or contracts between the Corporation and one or more of its directors or
officers or between the Corporation and any other corporation, partnership,
association or other organization in which one or more of its directors or
officers are directors or officers or have a financial interest.


                                   ARTICLE IX


         A. WRITTEN CONSENT. At any time after the closing of an initial public
offering of the Corporation's Common Stock, any action required or permitted to
be taken by the stockholders of the Corporation shall be effected only at a duly
called annual or special meeting of stockholders of the Corporation and shall
not be effected by consent in writing by the holders of outstanding stock
pursuant to Section 228 of the DGCL or any other provision of the DGCL.

         B. SPECIAL MEETINGS. Special meetings of stockholders of the
Corporation may be called upon not less than ten (10) nor more than sixty (60)
days' written notice only by the Board of Directors pursuant to a resolution
approved by a majority of the Board of Directors.

         C. AMENDMENT. Notwithstanding anything contained in this Amended and
Restated Certificate of Incorporation to the contrary, the affirmative vote of
the holders of at least 80% of 



                                       -6-



the shares entitled to vote generally in the election of directors shall be
required to amend, alter or repeal, or to adopt any provision inconsistent with,
this Article IX.


                                    ARTICLE X

         Meetings of stockholders may be held within or without the State of
Delaware as the By-laws of the Corporation may provide. The books of the
Corporation may be kept outside the State of Delaware at such place or places as
may be designated from time to time by the Board of Directors of the Corporation
or in the By-laws of the Corporation. Election of directors need not be by
written ballot unless the By-laws of the Corporation so provide.


                                   ARTICLE XI

         Whenever a compromise or arrangement is proposed between the
Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under the
provisions of Section 291 of the DGCL or on the application of trustees in
dissolution or of any receiver or receivers appointed for the Corporation under
the provisions of Section 279 of the DGCL, order a meeting of the creditors or
class of creditors and/or the stockholders or class of stock of the Corporation,
as the case may be, to be summoned in such manner as the said court directs. If
a majority in number representing three-fourths (3/4) of the value of the
creditors or class of creditors and/or the stockholders or class of stockholders
of the Corporation, as the case may be, agree to any compromise or arrangement
or to any reorganization of the Corporation as a consequence of such compromise
or arrangement, said compromise or arrangement or said reorganization shall, if
sanctioned by the Court to which said application has been made, be binding on
all the creditors or class of creditors and/or on all the stockholders or class
of stockholders, of the Corporation, as the case may be, and also on the
Corporation.


                                   ARTICLE XII

         In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to adopt, alter amend or
repeal the By-laws of the Corporation. The By-laws of the Corporation may be
altered, amended, or repealed or new By-laws may be adopted, by the Board of
Directors in accordance with the preceding sentence or by the vote of the
holders of at least 80% of the voting power of the shares of the Corporation
entitled to vote generally in the election of directors at an annual or special
meeting of stockholders, provided that if such alteration, amendment, repeal or
adoption of new By-laws is effected at a duly called special meeting, notice of
such alteration, amendment, repeal or adoption of new By-laws is contained in
the notice of such special meeting.
