(i) 400,000,000 shares of Common Stock, $.00001 par value per share ("Common
Stock"), and (ii) 10,000,000 shares of Preferred Stock, $.01 par value per share
("Preferred Stock").

     The following is a statement of the designations and the powers, privileges
and rights, and the qualifications, limitations or restrictions thereof in
respect of each class of capital stock of the Corporation.

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

     1. General. The voting, dividend and liquidation rights of the holders of
        -------
the Common Stock are subject to and qualified by the rights of the holders of
the Preferred Stock of any series as may be designated by the Board of Directors
upon any issuance of the Preferred Stock of any series.

     2. Voting. The holders of the Common Stock shall have voting rights at all
        ------
meetings of stockholders, each such holder being entitled to one vote for each
share thereof held by such holder. There shall be no cumulative voting.

     The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the Corporation
entitled to vote, irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law of Delaware.

                                      -2-


     3.  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.

     4.  Liquidation.  Upon the dissolution or liquidation of the Corporation,
         -----------
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive all assets of the Corporation available for distribution to its
stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

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

     Preferred Stock may be issued from time to time in one or more series, each
of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided. Any shares of
Preferred Stock which may be redeemed, purchased or acquired by the Corporation
may be reissued except as otherwise provided by law. Different series of
Preferred Stock shall not be construed to constitute different classes of shares
for the purposes of voting by classes unless expressly provided.

     Authority is hereby expressly granted to the Board of Directors from time
to time to issue the Preferred Stock in one or more series, and in connection
with the creation of any such series, by resolution or resolutions providing for
the issuance of the shares thereof, to determine and fix such voting powers,
full or limited, or no voting powers, and such designations, preferences and
relative participating, optional or other special rights, and qualifications,
limitations or restrictions thereof, including without limitation thereof,
dividend rights, conversion rights, redemption privileges and liquidation
preferences, as shall be stated and expressed in such resolutions, all to the
full extent now or hereafter permitted by the General Corporation Law of
Delaware. Without limiting the generality of the foregoing, the resolutions
providing for issuance of any series of Preferred Stock may provide that such
series shall be superior or rank equally or be junior to the Preferred Stock of
any other series to the extent permitted by law. Except as otherwise provided in
this Certificate of Incorporation, no vote of the holders of the Preferred Stock
or Common Stock shall be a prerequisite to the designation or issuance of any
shares of any series of the Preferred Stock authorized by and complying with the
conditions of this Certificate of Incorporation, the right to have such vote
being expressly waived by all present and future holders of the capital stock of
the Corporation.

                                      -3-


     FIFTH. Except as otherwise provided herein, the Corporation reserves the
right to amend, alter, change or repeal any provision contained in this
Certificate of Incorporation, in the manner now or hereafter prescribed by
statute and this Certificate of Incorporation, and all rights conferred upon
stockholders herein are granted subject to this reservation.

     SIXTH. In furtherance and not in limitation of the powers conferred upon it
by the laws of the State of Delaware, the Board of Directors shall have the
power to adopt, amend, alter or repeal the Corporation's By-laws. The
affirmative vote of a majority of the directors present at any regular or
special meeting of the Board of Directors at which a quorum is present shall be
required to adopt, amend, alter or repeal the Corporation's By-laws. The
Corporation's By-laws also may be adopted, amended, altered or repealed by the
affirmative vote of the holders of at least seventy-five percent (75%) of the
votes which all the stockholders would be entitled to cast in any annual
election of directors or class of directors. Notwithstanding any other
provisions of law, this Certificate of Incorporation or the By-Laws of the
Corporation, and notwithstanding the fact that a lesser percentage may be
specified by law, the affirmative vote of the holders of at least seventy-five
percent (75%) of the votes which all the stockholders would be entitled to cast
in any annual election of directors or class of directors shall be required to
amend or repeal, or to adopt any provision inconsistent with, this Article
SIXTH.

     SEVENTH. Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability. No amendment to or repeal of this provision shall apply to or have
any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal.

     EIGHTH. 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, partner, employee 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

                                      -4-


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.

     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, partner, employee or trustee of, or in a
similar capacity with, another corporation, 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, to the extent permitted by law,
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 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 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 EIGHTH, 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'

                                      -5-


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 purposes 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 action, suit, proceeding or
investigation, other than as provided below in this Section 4.  The Indemnitee
shall have the right to employ his own counsel in connection with such action,
suit, proceeding or investigation, 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, suit, proceeding or
investigation or (iii) the Corporation shall not in fact have employed counsel
to assume the defense of such action, suit, proceeding or investigation, 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.  The Corporation shall not be
required to indemnify the Indemnitee under this Article for any amounts paid in
settlement of any action, suit, proceeding or investigation effected without its
written consent.  The Corporation shall not settle any action, suit, proceeding
or investigation in any manner

                                      -6-


which would impose any penalty or limitation on the Indemnitee without the
Indemnitee's written consent. Neither the Corporation nor the Indemnitee will
unreasonably withhold or delay its consent to any proposed settlement.

     5.  Advance of Expenses. Subject to the provisions of Section 6 of this
         -------------------
Article EIGHTH, in the event that the Corporation does not assume the defense
pursuant to Section 4 of this Article EIGHTH 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
                --------  -------
the 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; and further provided that no such advancement of
expenses shall be made if it is determined (in the manner described in Section
6) that (i) 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, or (ii) with respect to any criminal action or proceeding, the
Indemnitee had reasonable cause to believe his conduct was unlawful.  Such
undertaking shall be accepted without reference to the financial ability of the
Indemnitee 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 EIGHTH,
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 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 of this
Article EIGHTH the Corporation determines within such 60-day period that the
Indemnitee did not meet the applicable standard of conduct set forth in Section
1, 2 or 5 of this Article EIGHTH, as the case may be.  Any such indemnification,
unless ordered by a court, shall be made with respect to requests under Section
1 or 2 only as authorized in the specific case upon a determination by the
Corporation that the indemnification of the Indemnitee is proper because the
Indemnitee has met 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 (a) by
a majority vote of the directors of the

                                      -7-


Corporation consisting of persons who are not at that time parties to the
action, suit or proceeding in question ("disinterested directors"), whether or
not a quorum, (b) by a majority vote of a committee of disinterested directors
designated by majority vote of disinterested directors, whether or not a quorum,
(c), if there are no disinterested directors, or if disinterested directors so
direct, by independent legal counsel (who may, to the extent permitted by law,
be regular legal counsel to the Corporation) in a written opinion, or (d) by the
stockholders of the Corporation.

     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.  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 of this Article EIGHTH 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.  Limitations.  Notwithstanding anything to the contrary in this Article,
         -----------
except as set forth in Section 7 of the Article EIGHTH, the Corporation shall
not indemnify an Indemnitee 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.  Notwithstanding anything to the contrary
in this Article, the Corporation shall not indemnify an Indemnitee to the extent
such Indemnitee is reimbursed from the proceeds of insurance, and in the event
the Corporation makes any indemnification payments to an Indemnitee and such
Indemnitee is subsequently reimbursed from the proceeds of insurance, such
Indemnitee shall promptly refund such indemnification payments to the
Corporation to the extent of such insurance reimbursement.

     9.  Subsequent Amendment. No amendment, termination or repeal of this
         --------------------
Article or of the relevant provisions of the General Corporation Law 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 investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

                                      -8-


     10.  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.

     11.  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.

     12.  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 Delaware.

     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 any applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

                                      -9-


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

     NINTH. This Article is inserted for the management of the business and for
the conduct of the affairs of the Corporation.

     1. Number of Directors; Election of Directors. The number of directors of
        ------------------------------------------
the Corporation shall not be less than three. The exact number of directors
within the limitations specified in the preceding sentence shall be determined
from time to time by, or in the manner provided in, the By-laws of the
Corporation. Election of directors need not be by written ballot, except as and
to the extent provided in the By-laws 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. If a fraction is contained in
the quotient arrived at by dividing the authorized number of directors by three,
then, if such fraction is one-third, the extra director shall be a member of
Class I, and if such fraction is two-thirds, one of the extra directors shall be
a member of Class I and one of the extra directors shall be a member of Class
II, unless otherwise provided by resolution of the Board of Directors.

     3. 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, that each initial director in Class I shall serve for a
term expiring at the Corporation's annual meeting of stockholders held in 2001;
each initial director in Class II shall serve for a term expiring at the
Corporation's annual meeting of stockholders held in 2002; and each initial
director in Class III shall serve for a term expiring at the Corporation's
annual meeting of stockholders held in 2003; provided further, that the term of
each director shall continue until the election and qualification of his
successor and be subject to his earlier death, resignation or removal.

     4. Allocation of Directors Among Classes in the Event of Increases or
        ------------------------------------------------------------------
Decreases in the Authorized 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 a director of the class of which he is a
member until the expiration of his current term, subject to his earlier death,
resignation or removal and (ii) the newly created or eliminated directorships
resulting from such increase or decrease shall be apportioned by the Board of
Directors among

                                      -10-


the three classes of directors in accordance with the provisions of Section 2 of
this Article NINTH. To the extent possible, consistent with the provisions of
Section 2 of this Article NINTH, any newly created directorships shall be added
to those classes whose terms of office are to expire at the latest dates
following such allocation, and any newly eliminated directorships shall be
subtracted from those classes whose terms of offices are to expire at the
earliest dates following such allocation, unless otherwise provided from time to
time by resolution of the Board of Directors.

     5.  Quorum. A majority of the directors at any time in office shall
         ------
constitute a quorum for the transaction of business. 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 director so disqualified, provided that
in no case shall less than one-third of the number of directors fixed pursuant
to Section 1 of this Article NINTH constitute a quorum. If at any meeting of the
Board of Directors there shall be less than such a quorum, 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.

     6.  Action at Meeting. Every act or decision done or made by a majority of
         -----------------
the directors present at a meeting duly held at which a quorum is present shall
be regarded as the act of the Board of Directors unless a greater number is
required by law, by this Certificate of Incorporation, or by the By-laws of the
Corporation.

     7.  Removal. Directors of the Corporation may be removed only for cause by
         -------
the affirmative vote of the holders of at least seventy-five percent (75%) of
the votes which all the stockholders would be entitled to cast in any annual
election of directors or class of directors.

     8.  Vacancies.  Any vacancy in the Board of Directors, however occurring,
         ---------
including a vacancy resulting from an enlargement of the Board, shall be filled
only by vote of a majority of the directors then in office, although less than a
quorum, or by a sole remaining director.  A director elected to fill a vacancy
shall be elected to hold office until the next election of the class for which
such director shall have been chosen, subject to the election and qualification
of his successor and to his earlier death, resignation or removal.

     9.  Stockholder Nominations and Introduction of Business, Etc. Advance
         ---------------------------------------------------------
