proposal to be presented at an annual meeting shall be received at the
Corporation's principal executive offices not less than 120 calendar days in
advance of the date that the Corporation's (or the Corporation's predecessor's)
proxy statement was released to stockholders in connection with the previous

of stock entitled to vote thereat who are present, in person or represented by
proxy, shall have the power to adjourn the meeting from time to time, without

represented, any business may be transacted which might have been transacted at
the meeting as originally notified. If the adjournment is for more than thirty

represented by proxy shall decide any question brought before such meeting,
unless the question is one on which by express provision of the General
Corporation Laws of the State of Delaware or of the Certificate of
Incorporation, a different vote is required in which case such express provision
shall govern and control the decision of such question. Each stockholder shall
at every meeting of the stockholders be entitled to one vote in person or by
proxy for each share of the capital stock having voting power held by such
stockholder, but no proxy shall be voted on after three (3) years from its date,
unless the proxy provides for a longer period.

         Section 8. Prior to the IPO, unless otherwise provided in the
Certificate of Incorporation, any action required to be taken at any annual or
special meeting of stockholders of the Corporation, or any action which may be
taken at any annual or special meeting of such stockholders, may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted, provided, however, that upon
the closing of the IPO, this Section 8 of Article II shall no longer be
effective and shall be null and void. Prompt notice of the taking of the
corporate action without a meeting by less than unanimous written consent shall
be given to those stockholders who have not consented in writing.

         Section 1. The number of directors shall be between four (4) and seven
(7), with the number initially set at four (4), and thereafter shall be fixed
from time to time exclusively by the Board of Directors pursuant to a resolution
adopted by a majority of the total number of authorized directors (whether or
not there exist any vacancies in previously authorized directorships at the time
any such resolution is presented to the Board for adoption). The four (4)
directors shall be elected at the annual meeting of the stockholders, who shall
vote for such directors as provided in the Certificate of Incorporation. Upon
the closing of the IPO, the directors shall be divided into three (3) classes,
with the term of office of the first class, which 


                                       3
   5
class shall initially consist of one (1) director, to expire at the first annual
meeting of stockholders held after the IPO; the term of office of the second
class, which class shall initially consist of one (1) director, to expire at the
second annual meeting of stockholders held after the IPO; the term of office of
the third class, which class shall initially consist of two (2) directors, to
expire at the third annual meeting of stockholders held after the IPO; and
thereafter for each such term to expire at each third succeeding annual meeting
of stockholders after such election. Upon the closing of the IPO, a vacancy
resulting from the removal of a director by the stockholders as provided in
Article III, Section 2 below may be filled by the Board of Directors. All
directors shall hold office until the expiration of the term for which elected
and until their respective successors are elected, except in the case of the
death, resignation or removal of any director. Directors need not be
stockholders.

         Section 2. Prior to the IPO, any vacancies on the Board of Directors
shall be filled by the stockholders of the Corporation entitled to fill such
vacancy as provided in the Certificate of Incorporation and the director so
chosen shall hold office until such director's successor is elected and
qualified. Vacancies from any newly created directorships resulting from any
increase in the authorized number of directors may be filled by all of the
directors then in office, and the directors so chosen shall hold office until
such directors' successors are elected and qualified. Upon the closing of the
IPO, subject to the rights of the holders of any series of Preferred Stock then
outstanding, newly created directorships resulting from any increase in the
authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification or other cause
(other than removal from office by a vote of the stockholders) may be filled
only by a majority vote of the directors then in office, though less than a
quorum, and directors so chosen shall hold office for a term expiring at the
next annual meeting of stockholders at which the term of office of the class to
which they have been elected expires. No decrease in the number of directors
constituting the Board of Directors shall shorten the term of any incumbent
director.

         Section 3. The business of the Corporation shall be managed by its
Board of Directors which shall have and exercise full power in the management
and conduct of the business and affairs of the Corporation and do all such
lawful acts and things as are not by statute or by the Certificate of
Incorporation of by these Bylaws directed or required to be exercised or done by
the stockholders.

shall be held immediately following the annual meeting of shareholders and in
the same place as the annual meeting of shareholders, and no notice to the newly
elected directors of such meeting shall be necessary in order legally to hold
the meeting provided a quorum shall be present. In the event such meeting is not
held, the meeting may be held at such time and place as shall be 


                                       4

receipt of confirmation of transmission); special meetings shall be called by
the President or Secretary in like manner or on like notice on the written
request of one director. Upon the closing of the IPO, special meetings of the
board may be called by the President or Chief Executive Officer or by resolution
adopted by at least one-third (1/3) of the directors then holding office, though
less than a quorum, on one (1) day's notice to each director, either personally
or by mail or by telegram or facsimile (with receipt of confirmation of
transmission).

         Section 8. At all meetings of the board, a majority of all the
directors of the Corporation shall constitute a quorum and the act of a majority
of the directors present at any meeting at which there is a quorum shall be the
act of the Board of Directors, except as may be otherwise specifically provided
by the General Corporation Law of the State of Delaware, by the Certificate of
Incorporation or by these Bylaws. If a quorum shall not be present at any
meeting of the Board of Directors, the directors present thereat may adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

         Section 9. Unless otherwise restricted by the Certificate of
Incorporation or these Bylaws, any action required or permitted to be taken at

without a meeting, if all members of the board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board or committee.

         Section 10. Members of the Board of Directors, or any committee
designated by the board, may participate in a meeting of such board or committee
by means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other, and

and affairs of the Corporation, and may authorize the seal of the Corporation to
be affixed to all 


                                       5

disqualification of any member of such committee or committees and any alternate
members, the member or members thereof present at any meeting and not
disqualified from voting, whether or not such members constitute a quorum, may
unanimously appoint another member of the Board of Directors to act the meeting
in the place of any such absent or disqualified member. Such committee or
committees shall have such name or names as may be determined from time to time
by resolution adopted by the Board of Directors. Each committee shall keep
regular minutes of its meetings and report the same to the Board of Directors
when required.

         Section 12. The directors may be paid their expenses, if any, of
attendance at each meeting of the Board of Directors and may be paid a fixed sum
for attendance at each meeting of the Board of Directors or a stated salary as
director. No such payment shall preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor. Members
of special or standing committee may be allowed like compensation for attending
committee meetings.

         Section 1. Right to Indemnification. Each person who was or is made a
party or is threatened to be made a party to or is involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative

the Corporation or is or was serving at the request of the Corporation as a
director, officer or employee of another corporation, or of a partnership, joint

official capacity as a director, officer or employee or in any other capacity
while serving as a director, officer or employee, shall be indemnified and held
harmless by the Corporation to the fullest extent authorized by Delaware 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 expenses, liability and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties,
amounts paid or to be paid in settlement and amounts expended in seeking
indemnification granted to such person under applicable law, this Bylaw or any
agreement with the Corporation) reasonably incurred or suffered by such person
in connection therewith and such indemnification shall continue as to a person
who has ceased to be a director, officer or employee and shall inure to the
benefit of his or her heirs, executors and administrators; provided, however,
that, except as provided in Section 3 of this Article VIII, the Corporation

Proceeding (or part thereof) was authorized and approved by the Board of
Directors of the Corporation, or (c) the action, suit or Proceeding (or part
thereof) is brought to establish or enforce a right to indemnification under an
indemnity agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law. Such right shall be a
contract right and shall include the right to be paid by the Corporation
expenses incurred in defending any such Proceeding in advance of its final
disposition; provided. 


                                       11

however. that, unless" the Delaware General Corporation Law then so prohibits,
the payment of such expenses incurred by a director or officer of the
Corporation in his or her capacity as a director or officer (and not in any
other capacity in which service was or is tendered by such person while a
director or officer, including, without limitation. service to an employee
benefit plan) in advance of the final disposition of such 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 should be
determined ultimately that such director or officer is not entitled to be
indemnified under this Section or otherwise.

         Section 2. Prepayment of Expenses. The Corporation shall pay the
expenses incurred by an officer or director in defending any Proceeding in
advance of its final disposition, provided however, that the payment of expenses
incurred by a director or officer in advance of the final disposition of a
Proceeding shall be made only upon receipt of an undertaking by the director or
officer to repay all amounts advanced if it should be ultimately determined that
the director or officer is not entitled to be indemnified under this Article or
otherwise. For purposes of this Section 2, the terms "expenses incurred by an
officer or director in defending any Proceeding" shall not include any fees or
expenses incurred in connection with the affirmative prosecution of any claim
against the Corporation by such director or officer, whether as plaintiff,
counterclaimant, cross-claimant or otherwise.

         Section 3. Claims. If a claim for indemnification or payment of
expenses under this Article is not paid in full within sixty (60) days after a
written claim therefor has been received by the Corporation, the claimant may
file suit to recover the unpaid amount of such claim and, if successful in whole
or in part, shall be entitled to be paid the expense of prosecuting such claim.
In any such action, the Corporation shall have the burden of proving that the
claimant was not entitled to the requested indemnification or payment of
expenses under applicable law.

         Section 4. Non-exclusivity of Rights. The rights conferred on any
person by this Article VIII shall not be exclusive of any other rights which
such person may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, these Bylaws, agreement, vote of stockholders or
disinterested directors or otherwise.

to indemnify any person who was or is serving at its request as a director or
officer of another corporation, partnership, joint venture, trust enterprise or
non-profit entity shall be reduced by any amount such person may collect as
indemnification from such other corporation, partnership, joint venture, trust,
enterprise or non-profit enterprise.

         Section 6. Amendment or Repeal. Any repeal or modification of the
foregoing provisions of this Article VIII shall not adversely affect any right
or protection hereunder of any person in respect of any act or omission
occurring prior to the time of such repeal or modification.

         Section 7. Insurance. The Corporation shall maintain insurance to the
extent reasonably available, at its expense, to protect itself and any such
director, officer, employee or agent of the Corporation or another corporation,
partnership, joint venture, trust or other 


                                       12

liability or loss under the Delaware General Corporation Law.

or repealed at any regular meeting of the Board of Directors or at any special
meeting of the Board of Directors if notice of such alteration or repeal is
contained in the notice of such special meeting. Prior to the closing of the

directors then serving and approved by the holders of at least a majority of the
total number of shares of Preferred Stock then outstanding. Upon the closing of

repeal Bylaws of the Corporation. Any adoption, amendment or repeal of Bylaws of
the Corporation by the Board of Directors shall require the approval of at least
two-thirds (2/3) of the total number of authorized directors (whether or not
there exist any vacancies in previously authorized directorships at the time any
resolution providing for adoption, amendment or repeal is presented to the Board
of Directors). The stockholders shall also have power to adopt, amend or repeal
the Bylaws of the Corporation. Any adoption, amendment or repeal of Bylaws of

or by this Certificate of Incorporation, the affirmative vote of the holders of
at least sixty-six and two-thirds percent (66-2/3%) 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.


         These First Amended and Restated Bylaws were adopted by all the
directors of the Corporation on the 11th day of October, 1997.
