            SECOND AMENDED AND RESTATED CERTIFICATE OF INCORPORATION

                                       OF

                        WORKGROUP TECHNOLOGY CORPORATION


         The undersigned, an authorized officer of Workgroup Technology
Corporation, a corporation organized and existing under the laws of the State of
Delaware, hereby certifies as follows:

         1.   The name of the corporation is Workgroup Technology Corporation.
The original certificate of incorporation of the corporation was filed with the
Secretary of State of the State of Delaware on May 11, 1992. The certificate of
incorporation, as amended, was amended and restated on March 26, 1996.

         2.   The amendment and restatement of the certificate of incorporation
has been duly adopted by both the Board of Directors and the stockholders of the
corporation in accordance with the provisions of Sections 141, 222, 242 and 245
of the General Corporation Law of the State of Delaware.

         3.   Pursuant to Sections 242 and 245 of the General Corporation Law of
the State of Delaware, this Second Amended and Restated Certificate of
Incorporation restates and integrates and further amends the provisions of the
corporation's certificate of incorporation as heretofore amended, restated or
supplemented.

         4.   The text of the Second Amended and Restated Certificate of
Incorporation reads in its entirety as follows:

         FIRST. The name of the Corporation is Workgroup Technology Corporation
(the "Corporation").

         SECOND. The address of the registered office of the Corporation in the
State of Delaware is 1209 Orange Street, Wilmington, County of New Castle,
Delaware 19801. The name of its registered agent at such address is The
Corporation Trust Company.

         THIRD. The nature of the business or purposes to be conducted or
promoted is to engage in any lawful act or activity for which corporations may
be organized under the General Corporation Law of the State of Delaware.

         FOURTH. Effective upon the filing of this Second Amended and Restated
Certificate of Incorporation with the Secretary of State of the State of
Delaware (the "Effective Date"), each share of Common Stock, $.01 par value per
share (the "Old Common Stock"), then issued and outstanding or held in the
treasury of the Corporation at the close of business on the Effective Date shall
automatically be reclassified, converted and changed into 0.25 share of Common
Stock, $.01 par value per share ("New Common Stock"), of the Corporation without
any further action by the holders of such shares of Old Common Stock (and any
fractional shares resulting from such exchange will not be issued but will be
rounded up and exchanged for one (1) whole share of New Common Stock). Each
stock certificate representing shares of Old Common Stock
<PAGE>

shall thereafter represent that number of shares of New Common Stock into which
the shares of Old Common Stock represented by such certificate shall have been
reclassified; provided, however, that each person holding of record a stock
              --------  -------
certificate or certificates that represented shares of Old Common Stock shall
receive, upon surrender of such certificate or certificates, a new certificate
or certificates evidencing and representing the number of shares of New Common
Stock to which such person is entitled. The New Common Stock issued in this
exchange shall have the same rights and preferences as the Common Stock (as
defined below).

         The total number of shares of all classes of capital stock which the
Corporation shall have authority to issue is 31,000,000 shares, consisting of
30,000,000 shares of Common Stock with a par value of $.01 per share (the
"Common Stock") and 1,000,000 shares of Preferred Stock with a par value of $.01
per share (the "Preferred Stock").

         A description of the respective classes of stock and a statement of the
designations, powers, preferences and rights, and the qualifications,
limitations and restrictions of the Preferred Stock and Common Stock are as
follows:

         A.    COMMON STOCK
               ------------

         1.    General.  All shares of Common Stock will be identical and will
               -------
entitle the holders thereof to the same rights, powers and privileges. The
rights, powers and privileges of the holders of the Common Stock are subject to
and qualified by the rights of holders of the Preferred Stock.

         2.    Dividends.  Dividends may be declared and paid on the Common
               ---------
Stock from funds lawfully available therefor as and when determined by the Board
of Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

         3.    Dissolution, Liquidation or Winding Up. In the event of any
               --------------------------------------
dissolution, liquidation or winding up of the affairs of the Corporation,
whether voluntary or involuntary, each issued and outstanding share of Common
Stock shall entitle the holder thereof to receive an equal portion of the net
assets of the Corporation available for distribution to the holders of Common
Stock, subject to any preferential rights of any then outstanding Preferred
Stock.

         4.    Voting Rights. Except as otherwise required by law or this Second
               -------------
Amended and Restated Certificate of Incorporation, each holder of Common Stock
shall have one vote in respect of each share of stock held of record by such
holder on the books of the Corporation for the election of directors and on all
matters submitted to a vote of stockholders of the Corporation. Except as
otherwise required by law or provided herein, holders of Common Stock shall vote
together with holders of the Preferred Stock as a single class, subject to any
special or preferential voting rights of any then outstanding Preferred Stock.
There shall be no cumulative voting.

         B.    PREFERRED STOCK
               ---------------

         The Preferred Stock may be issued in one or more series at such time or
times and for such consideration or considerations as the Board of Directors of
the Corporation may determine. Each series shall be so designated as to
distinguish the shares thereof from the shares of all other series and classes.
Except as otherwise provided in this Second Amended and Restated Certificate of
Incorporation, different series of Preferred Stock shall not be construed to
constitute different classes of shares for the purpose of voting by classes.

                                       2
<PAGE>

         The Board of Directors is expressly authorized to provide for the
issuance of all or any shares of the undesignated Preferred Stock in one or more
series, each with such designations, preferences, voting powers (or special,
preferential or no voting powers), relative, participating, optional or other
special rights and privileges and such qualifications, limitations or
restrictions thereof as shall be stated in the resolution or resolutions adopted
by the Board of Directors to create such series, and a certificate of said
resolution or resolutions (a "Certificate of Designation") shall be filed in
accordance with the General Corporation Law of the State of Delaware. The
authority of the Board of Directors with respect to each such series shall
include, without limitation of the foregoing, the right to provide that the
shares of each such series may be: (i) subject to redemption at such time or
times and at such price or prices; (ii) entitled to receive dividends (which may
be cumulative or non-cumulative) at such rates, on such conditions, and at such
times, and payable in preference to, or in such relation to, the dividends
payable on any other class or classes or any other series; (iii) entitled to
such rights upon the dissolution of, or upon any distribution of the assets of,
the Corporation; (iv) convertible into, or exchangeable for, shares of any other
class or classes of stock, or of any other series of the same or any other class
or classes of stock of the Corporation at such price or prices or at such rates
of exchange and with such adjustments, if any; (v) entitled to the benefit of
such limitations, if any, on the issuance of additional shares of such series or
shares of any other series of Preferred Stock; or (vi) entitled to such other
preferences, powers, qualifications, rights and privileges, all as the Board of
Directors may deem advisable and as are not inconsistent with law and the
provisions of this Second Amended and Restated Certificate of Incorporation.

         FIFTH.     The Corporation is to have perpetual existence.

         SIXTH.     The following provisions are included for the management of
the business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its Board of Directors and stockholders:

              1.    The business and affairs of the Corporation shall be managed
by or under the direction of the Board of Directors of the Corporation.

              2.    The Board of Directors of the Corporation is expressly
authorized to adopt, amend or repeal the By-laws of the Corporation, subject to
any limitation thereof contained in the By-laws. The stockholders shall also
have the power to adopt, amend or repeal the By-laws of the Corporation;
provided, however, that, in addition to any vote of the holders of any class or
series of stock of the Corporation required by law or by this Second Amended and
Restated Certificate of Incorporation, the affirmative vote of the holders of at
least seventy-five percent (75%) of the voting power of all of the then
outstanding shares of the capital stock of the Corporation entitled to vote
generally in the election of directors, voting together as a single class, shall
be required to adopt, amend or repeal any provision of the By-laws of the
Corporation.

              3.    Stockholders of the Corporation may not take any action by
written consent in lieu of a meeting.

              4.    Special meetings of stockholders may be called at any time
only by the President, the Chairman of the Board of Directors (if any) or a
majority of the Board of Directors. Business transacted at any special meeting
of stockholders shall be limited to matters relating to the purpose or purposes
stated in the notice of meeting.

                                       3
<PAGE>

              5.   The books of the Corporation may be kept at such place
within or without the State of Delaware as the By-laws of the Corporation may
provide or as may be designated from time to time by the Board of Directors of
the Corporation.

         SEVENTH.

         1.   Number of Directors. The number of directors which shall
              -------------------
constitute the whole Board of Directors shall be determined by resolution of a
majority of the Board of Directors, but in no event shall the number of
directors be less than three. The number of directors may be decreased at any
time and from time to time by a majority of the directors then in office, but
only to eliminate vacancies existing by reason of the death, resignation,
removal or expiration of the term of one or more directors. The directors shall
be elected at the annual meeting of stockholders by such stockholders as have
the right to vote on such election. Directors need not be stockholders of the
Corporation.

         2.   Classes of Directors.  The Board of Directors shall be and is
              --------------------
divided into three classes: Class I, Class II and Class III. No one class shall
have more than one director more than any other class.

         3.   Election of Directors.  Elections of directors need not be by
              ---------------------
written ballot except as and to the extent provided in the By-laws of the
Corporation.

         4.   Terms of Office. Each director shall serve for a term ending on
              ---------------
the date of the third annual meeting following the annual meeting at which such
director was elected; provided, however, that each initial director in Class I
shall serve for a term ending on the date of the annual meeting next following
the end of the Corporation's fiscal year ending March 31, 1996; each initial
director in Class II shall serve for a term ending on the date of the annual
meeting next following the end of the Corporation's fiscal year ending March 31,
1997; and each initial director in Class III shall serve for a term ending on
the date of the annual meeting next following the end of the Corporation's
fiscal year ending March 31, 1998.

         5.   Allocation of Directors Among Classes in the Event of Increases or
              ------------------------------------------------------------------
Decreases in the Number of Directors. In the event of any increase or decrease
------------------------------------
in the authorized number of directors, (i) each director then serving as such
shall nevertheless continue as director of the class of which he or she is a
member until the expiration of such director's current term or his or her prior
death, retirement or resignation and (ii) the newly created or eliminated
directorships resulting from such increase or decrease shall be apportioned by
the Board of Directors among the three classes of directors so as to ensure that
no one class has more than one director more than any other class. To the extent
possible, consistent with the foregoing rule, any newly created directorships
shall be added to those classes whose terms of office are to expire at the
earliest dates following such allocation. No decrease in the number of director
constituting the whole Board of Directors shall shorten the term of an incumbent
Director.

         6.   Tenure.  Notwithstanding any provisions to the contrary contained
              ------
herein, each director shall hold office until his or her successor is elected
and qualified, or until his or her earlier death, resignation or removal.

         7.   Vacancies. Unless and until filled by the stockholders, any
              ---------
vacancy in the Board of Directors, however occurring, including a vacancy
resulting from an enlargement of the Board of Directors, may be filled only by
vote of a majority of the directors then in office, even if less than a quorum,
or by a sole remaining director. A director elected to fill a vacancy shall be

                                       4
<PAGE>

elected for the unexpired term of his or her predecessor in office, if
applicable, and a director chosen to fill a position resulting from an increase
in the number of directors shall hold office until the next election of the
class for which such director shall have been chosen and until his or her
successor is elected and qualified, or until his or her earlier death,
resignation or removal.

         8.   Quorum. A majority of the total number of the whole Board of
              ------
Directors shall constitute a quorum at all meetings of the Board of Directors.
In the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each such director
so disqualified; provided, however, that in no case shall less than one-third
(1/3) of the number so fixed constitute a quorum. In the absence of a quorum at
any such meeting, a majority of the directors present may adjourn the meeting
from time to time without further notice other than announcement at the meeting,
until a quorum shall be present.

         9.   Action at Meeting.  At any meeting of the Board of Directors at
              -----------------
which a quorum is present, the vote of a majority of those present shall be
sufficient to take any action, unless a different vote is specified by law or
the Corporation's By-laws.

         10.  Removal. Any one or more or all of the directors may be removed
              -------
without cause only by the holders of at least seventy-five percent (75%) of the
shares then entitled to vote at an election of directors. Any one or more or all
of the directors may be removed with cause only by the holders of at least a
majority of the shares then entitled to vote at an election of directors.

         11.  Stockholder Nominations and Introduction of Business, Etc.
              ----------------------------------------------------------
Advance notice of stockholder nominations for election of directors and other
business to be brought by stockholders before a meeting of stockholders shall be
given in the manner provided in the By-laws of the Corporation.

         12.  Rights of Preferred Stock.  The provisions of this Article are
              -------------------------
subject to the rights of the holders of any series of Preferred Stock from time
to time outstanding.

         EIGHTH. No director (including any advisory director) of the
Corporation shall be personally liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director notwithstanding
any provision of law imposing such liability; provided, however, that, to the
extent provided by applicable law, this provision shall not eliminate the
liability of a director (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 General Corporation Law of the State of Delaware,
or (iv) for any transaction from which the director derived an improper personal
benefit. No amendment to or repeal of this provision shall apply to or have any
effect on the liability or alleged liability of any director for or with respect
to any acts or omissions of such director occurring prior to such amendment or
repeal.

         NINTH. The Board of Directors of the Corporation, when evaluating any
offer of another party (a) to make a tender or exchange offer for any equity
security of the Corporation or (b) to effect a business combination, shall, in
connection with the exercise of its judgment in determining what is in the best
interests of the Corporation as whole, be authorized to give due consideration
to any such factors as the Board of Directors determines to be relevant,
including, without limitation:

         (i) the interests of the Corporation's stockholders, including the
      possibility that these interests might be best served by the continued
      independence of the Corporation;

                                       5
<PAGE>

         (ii) whether the proposed transaction might violate federal or state
      laws;

         (iii) not only the consideration being offered in the proposed
      transaction, in relation to the then current market price for the
      outstanding capital stock of the Corporation, but also to the market price
      for the capital stock of the Corporation over a period of years, the
      estimated price that might be achieved in a negotiated sale of the
      Corporation as a whole or in part or through orderly liquidation, the
      premiums over market price for the securities of other corporations in
      similar transactions, current political, economic and other factors
      bearing on securities prices and the Corporation's financial condition and
      future prospects; and

         (iv) the social, legal and economic effects upon employees, suppliers,
      customers, creditors and others having similar relationships with the
      Corporation, upon the communities in which the Corporation conducts its
      business and upon the economy of the state, region and nation.

In connection with any such evaluation, the Board of Directors is authorized to
conduct such investigations and engage in such legal proceedings as the Board of
Directors may determine.

         TENTH.

         1.   Actions, Suits and Proceedings Other Than by or in the Right of
              ---------------------------------------------------------------
the Corporation. The Corporation shall indemnify each 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 he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) (all such persons being
referred to hereafter as an "Indemnitee"), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner 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, had 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, shall 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, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful. Notwithstanding
anything to the contrary in this Article, except as set forth in Section 6
below, the Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by the Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation.

         2.   Actions or Suits by or in the Right of the Corporation. The
              ------------------------------------------------------
Corporation shall indemnify any Indemnitee 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, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation,

                                       6
<PAGE>

partnership, joint venture, trust or other enterprise (including any employee
benefit plan), or by reason of any action alleged to have been taken or omitted
in such capacity, against all expenses (including attorneys' fees) and amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with such action, suit or proceeding and any appeal therefrom, if he
acted in good faith and in a manner he reasonably believed to be in, or not
opposed to, the best interests of the Corporation, 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 of Delaware or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of such liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses (including attorneys' fees) which the Court of
Chancery of Delaware or such other court shall deem proper.

         3.   Indemnification for Expenses of Successful Party. Notwithstanding
              ------------------------------------------------
the other provisions of this Article, to the extent that an Indemnitee 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, or in defense of any
claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, he shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by him or on his behalf in connection
therewith. Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an
adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of
guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the
          ---- ----------
Indemnitee did not act in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purpose hereof to have been wholly successful with respect
thereto.

         4.   Notification and Defense of Claim. As a condition precedent to his
              ---------------------------------
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving him for which indemnity will or could be sought. With respect to any
action, suit, proceeding or investigation of which the Corporation is so
notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee. After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such claim,
other than as provided below in this Section 4. The Indemnitee shall have the
right to employ his own counsel in connection with such claim, but the fees and
expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the Corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of counsel for the Indemnitee shall be at the expense of the Corporation, except
as otherwise expressly provided by this Article. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above.

                                       7
<PAGE>

         5.   Advance of Expenses. Subject to the provisions of Section 6 below,
              -------------------
in the event that the Corporation does not assume the defense pursuant to
Section 4 of this Article of any action, suit, proceeding or investigation of
which the Corporation receives notice under this Article, any expenses
(including attorneys' fees) incurred by an Indemnitee in defending a civil or
criminal action, suit, proceeding or investigation or any appeal therefrom shall
be paid by the Corporation in advance of the final disposition of such matter,
provided, however, that the payment of such expenses incurred by an Indemnitee
--------  -------
in advance of the final disposition of such matter shall be made only upon
receipt of an undertaking by or on behalf of the Indemnitee to repay all amounts
so advanced in the event that it shall ultimately be determined that the
indemnitee is not entitled to be indemnified by the Corporation as authorized in
this Article. Such undertaking may be accepted without reference to the
financial ability of such person to make such repayment.

         6.   Procedure for Indemnification. In order to obtain indemnification
              -----------------------------
or advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the
Indemnitee shall submit to the Corporation a written request, including in such
request such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to determine whether and to what extent
the Indemnitee is entitled to indemnification or advancement of expenses. Any
such indemnification or advancement of expenses shall be made promptly, and in
any event within 60 days after receipt by the Corporation of the written request
of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the
Corporation determines, by clear and convincing evidence, within such 60-day
period that the Indemnitee did not meet the applicable standard of conduct set
forth in Section 1 or 2, as the case may be. Such determination shall be made in
each instance by (a) a majority vote of the directors of the Corporation who are
not at that time parties to the action, suit or proceeding in question
("disinterested directors"), even though less than a quorum, (b) if there are no
such disinterested directors, or if such disinterested directors so direct, by
independent legal counsel (who may be regular legal counsel to the corporation)
in a written opinion, (c) a majority vote of a quorum of the outstanding shares
of stock of all classes entitled to vote for directors, voting as a single
class, which quorum shall consist of stockholders who are not at that time
parties to the action, suit or proceeding in question, or (d) a court of
competent jurisdiction.

         7.   Remedies. The right to indemnification or advances as granted by
              --------
this Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6. Unless otherwise provided by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation. Neither the failure of the Corporation
to have made a determination prior to the commencement of such action that
indemnification is proper in the circumstances because the Indemnitee has met
the applicable standard of conduct, nor an actual determination by the
Corporation pursuant to Section 6 that the Indemnitee has not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that the Indemnitee has not met the applicable standard of conduct.
The Indemnitee's expenses (including attorneys' fees) incurred in connection
with successfully establishing his right to indemnification, in whole or in
part, in any such proceeding shall also be indemnified by the Corporation.

         8.   Subsequent Amendment. No amendment, termination or repeal of this
              --------------------
Article or of the relevant provisions of the General Corporation Law of the
State of Delaware or any other applicable laws shall affect or diminish in any
way the rights of any Indemnitee to indemnification under the provisions hereof
with respect to any action, suit, proceeding or

                                       8

investigation arising out of or relating to any actions, transactions or facts
occurring prior to the final adoption of such amendment, termination or repeal.

         9.   Other Rights. The indemnification and advancement of expenses
              ------------
provided by this Article shall not be deemed exclusive of any other rights to
which an Indemnitee seeking indemnification or advancement of expenses may be
entitled under any law (common or statutory), agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in any other capacity while holding office for the
Corporation, and shall continue as to an Indemnitee who has ceased to be a
director or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of the Indemnitee. Nothing contained in this
Article shall be deemed to prohibit, and the Corporation is specifically
authorized to enter into, agreements with officers and directors providing
indemnification rights and procedures different from those set forth in this
Article. In addition, the Corporation may, to the extent authorized from time to
time by its Board of Directors, grant indemnification rights to other employees
or agents of the Corporation or other persons serving the Corporation and such
rights may be equivalent to, or greater or less than, those set forth in this
Article.

         10.  Partial Indemnification. If an Indemnitee is entitled under any
              -----------------------
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

         11.  Insurance. The Corporation may purchase and 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 (including any employee benefit plan) against any expense,
liability or loss incurred by him in any such capacity, or arising out of his
status as such, whether or not the Corporation would have the power to indemnify
such person against such expense, liability or loss under the General
Corporation Law of the State of Delaware.

         12.  Merger or Consolidation. If the Corporation is merged into or
              -----------------------
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such merger or consolidation.

         13.  Savings Clause. If this Article or any portion hereof shall be
              --------------
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit, proceeding or investigation, whether civil,
criminal or administrative, including an action by or in the right of the
Corporation, to the fullest extent permitted by an applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

         14.  Definitions.  Terms used herein and defined in Section 145(h) and
              -----------
Section 145(i) of the General Corporation Law of the State of Delaware shall
have the respective meanings assigned to such terms in such Section 145(h) and
Section 145(i).

         15.  Subsequent Legislation. If the General Corporation Law of the
              ----------------------
State of Delaware is amended after adoption of this Article to expand further
the indemnification permitted to Indemnitees, then the Corporation shall
indemnify such persons to the fullest extent permitted by the General
Corporation Law of the State of Delaware, as so amended.

         ELEVENTH. The Corporation reserves the right to amend or repeal any
provision contained in this Second Amended and Restated Certificate of
Incorporation in the manner prescribed by the laws of the State of Delaware and
all rights conferred upon stockholders are granted subject to this reservation,
