                           ISTA PHARMACEUTICALS, INC.



                                    ARTICLE I

                                CORPORATE OFFICES

         1.1     REGISTERED OFFICE

         The registered office of the corporation shall be in the City of
Wilmington, County of New Castle, State of Delaware. The name of the registered
agent of the corporation at such location is The Corporation Trust Company.

         1.2     OTHER OFFICES

         The board of directors may at any time establish other offices at any
place or places where the corporation is qualified to do business.



                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

         2.1     PLACE OF MEETINGS

         Meetings of stockholders shall be held at any place, either within or
without the State of Delaware, as may be designated by the board of directors or
in the manner provided in these amended and restated bylaws. In the absence of
any such designation, stockholders' meetings shall be held at the registered
office of the corporation in the State of Delaware.

         2.2     ANNUAL MEETING

        The annual meeting of stockholders shall be held each year on a date and
at a time designated by the board of directors. In the absence of such
designation, the annual meeting of stockholders shall be held on the 15th day of
April of each year at 10:00 a.m. However, if such day falls on a


<PAGE>   6


weekend or a legal holiday, then the meeting shall be held at the same time and
place on the next succeeding business day. At the meeting, directors shall be
elected and any other proper business may be transacted.

         2.3     SPECIAL MEETING

         A special meeting of the stockholders may be called at any time by the
board of directors, or by the chairman of the board, or by the chief executive
officer, or by the president.

         If a special meeting is called by any person or persons other than the
board of directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or by telegraphic or
other facsimile transmission to the chairman of the board, the president or the
secretary of the corporation. No business may be transacted at such special
meeting otherwise than specified in such notice. The officer receiving the
request shall cause notice to be promptly given to the stockholders entitled to
vote, in accordance with the provisions of Sections 2.4 and 2.5 of this Article
II, that a meeting will be held at the time requested by the person or persons
calling the meeting, not less than ten (10) nor more than sixty (60) days after
the receipt of the request. Nothing contained in this paragraph of this Section
2.3 shall be construed as limiting, fixing, or affecting the time when a meeting
of stockholders called by action of the board of directors may be held.

         2.4     NOTICE OF STOCKHOLDERS' MEETINGS

         All notices of meetings with stockholders shall be in writing and shall
be sent or otherwise given in accordance with Section 2.6 of these amended and
restated bylaws not less than ten (10) nor more than sixty (60) days before the
date of the meeting to each stockholder entitled to vote at such meeting. The
notice shall specify the place, date, and hour of the meeting, and, in the case
of a special meeting, the purpose or purposes for which the meeting is called.

         2.5     ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS

         Subject to the rights of holders of any class or series of stock having
a preference over the Common Stock as to dividends or upon liquidation,

                  (i)      nominations for the election of directors, and

                  (ii)     business proposed to be brought before any
stockholder meeting

may be made by the board of directors or proxy committee appointed by the board
of directors or by any stockholder entitled to vote in the election of directors
generally if such nomination or business proposed is otherwise proper business
before such meeting. However, any such stockholder may nominate one or more
persons for election as directors at a meeting or propose business to be brought
before a meeting, or both, only if such stockholder has given timely notice in
proper written

                                      -2-

<PAGE>   7

form of its intent to make such nomination or nominations or to propose such
business. To be timely, such stockholder's notice must be delivered to or mailed
and received at the principal executive offices of the corporation not less than
one hundred twenty (120) calendar days in advance of the first anniversary date
of mailing of the corporation's proxy statement released to stockholders in
connection with the previous year's annual meeting of stockholders; provided,
however, that in the event that no annual meeting was held in the previous year
or the date of the annual meeting has been changed by more than thirty (30) days
from the date contemplated at the time of the previous year's proxy statement,
notice by the stockholder to be timely must be so received a reasonable time
before the solicitation is made. To be in proper form, a stockholder's notice to
the secretary shall set forth:

                           (a) the name and address of the stockholder who
         intends to make the nominations or propose the business and, as the
         case may be, of the person or persons to be nominated or of the
         business to be proposed;

                           (b) a representation that the stockholder is a holder
         of record of stock of the corporation entitled to vote at such meeting
         and, if applicable, intends to appear in person or by proxy at the
         meeting to nominate the person or persons specified in the notice;

                           (c) if applicable, a description of all arrangements
         or understandings between the stockholder and each nominee and any
         other person or persons (naming such person or persons) pursuant to
         which the nomination or nominations are to be made by the stockholder;

                           (d) such other information regarding each nominee or
         each matter of business to be proposed by such stockholder as would be
         required to be included in a proxy statement filed pursuant to the
         proxy rules of the Securities and Exchange Commission had the nominee
         been nominated, or intended to be nominated, or the matter been
         proposed, or intended to be proposed by the board of directors; and

                           (e) if applicable, the consent of each nominee to
         serve as director of the corporation if so elected.

         The chairman of the meeting shall refuse to acknowledge the nomination
of any person or the proposal of any business not made in compliance with the
foregoing procedure.

         2.6      MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

         Written notice of any meeting of stockholders, if mailed, is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the secretary or an assistant secretary or of the transfer agent of
the corporation that the notice has been given shall, in the absence of fraud,
be prima facie evidence of the facts stated therein.

                                      -3-

<PAGE>   8

         2.7     QUORUM

         The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the certificate of
incorporation. If, however, such quorum is not present or represented at any
meeting of the stockholders, then either (i) the Chairman of the meeting or (ii)
the stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented. At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

         2.8     ADJOURNED MEETING; NOTICE

         When a meeting is adjourned to another time or place, unless these
amended and restated bylaws otherwise require, notice need not be given of the
adjourned meeting if the time and place thereof are announced at the meeting at
which the adjournment is taken. At the adjourned meeting the corporation may
transact any business that might have been transacted at the original meeting.
If the adjournment is for more than thirty (30) days, or if after the
adjournment a new record date is fixed for the adjourned meeting, a notice of
the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.

         2.9     CONDUCT OF BUSINESS

         The chairman of any meeting of stockholders shall determine the order
of business and the procedure at the meeting, including such regulation of the
manner of voting and the conduct of business.

         2.10    VOTING

         The stockholders entitled to vote at any meeting of stockholders shall
be determined in accordance with the provisions of Section 2.13 of these amended
and restated bylaws, subject to the provisions of Sections 217 and 218 of the
Delaware General Corporation Law (relating to voting rights of fiduciaries,
pledgors and joint owners of stock and to voting trusts and other voting
agreements).

         Except as may be otherwise provided in the certificate of
incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

        Notwithstanding the foregoing, if the stockholders of the corporation
are entitled, pursuant to Sections 2115 and 301.5 of the California Corporations
Code, to cumulate their votes in the election of directors, each such
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes that such stockholder normally
is entitled to cast) only if the candidates' names have been properly placed in
nomination (in accordance with these

                                      -4-

<PAGE>   9

Amended and Restated Bylaws) prior to commencement of the voting, and the
stockholder requesting cumulative voting has given notice prior to commencement
of the voting of the stockholder's intention to cumulate votes. If cumulative
voting is properly requested, each holder of stock, or of any class or classes
or of a series or series thereof, who elects to cumulate votes shall be entitled
to as many votes as equals the number of votes that (absent this provision as to
cumulative voting) he or she would be entitled to cast for the election of
directors with respect to his or her shares of stock multiplied by the number of
directors to be elected by him, and he or she may cast all of such votes for a
single director or may distribute them among the number to be voted for, or for
any two or more of them, as he or she may see fit.

         2.11     WAIVER OF NOTICE

         Whenever notice is required to be given under any provision of the
Delaware General Corporation Law or of the certificate of incorporation or these
amended and restated bylaws, a written waiver, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders, directors, or members of a
committee of directors need be specified in any written waiver of notice unless
so required by the certificate of incorporation or these amended and restated
bylaws.

         2.12     STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Unless otherwise provided in the certificate of incorporation, any
action required to be taken at any annual or special meeting of stockholders of
a corporation, or any action that 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 or consents 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.

         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. If the action which is consented to is such as
would have required the filing of a certificate under any section of the
Delaware General Corporation Law if such action had been voted on by
stockholders at a meeting thereof, then the certificate filed under such section
shall state, in lieu of any statement required by such section concerning any
vote of stockholders, that written notice and written consent have been given as
provided in Section 228 of the Delaware General Corporation Law.

                                      -5-

         2.13     RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

         In order that the corporation may determine the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof, or entitled to express consent to corporate action in writing without a
meeting, or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion or exchange of stock or for the purpose of any other lawful
action, the board of directors may fix, in advance, a record date, which shall
not be more than sixty (60) nor less than ten (10) days before the date of such
meeting, nor more than sixty (60) days prior to any other action.

         If the board of directors does not so fix a record date:

                  (i) The record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held.

                  (ii) The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the board of directors is necessary, shall be the first date on which
a signed written consent is delivered to the corporation.

                  (iii) The record date for determining stockholders for any
other purpose shall be at the close of business on the day on which the board of
directors adopts the resolution relating thereto.

         A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the board of directors may fix a new record date for the
adjourned meeting.

         2.14     PROXIES

         Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for such stockholder by a written
proxy, signed by such stockholder and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period. A proxy
shall be deemed signed if such stockholder's name is placed on the proxy by any
reasonable means including, but not limited to, by facsimile signature, manual
signature, typewriting, telegraphic transmission or otherwise, by such
stockholder or such stockholder's attorney-in-fact. The revocability of a proxy

         2.15     LIST OF STOCKHOLDERS ENTITLED TO VOTE

         The officer who has charge of the stock ledger of a corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present. Such list shall
presumptively determine the identity of the stockholders entitled to vote at the
meeting and the number of shares held by each of them.

                                   ARTICLE III

                                    DIRECTORS

         3.1     POWERS

         Subject to the provisions of the Delaware General Corporation Law and
any limitations in the certificate of incorporation or these amended and
restated bylaws relating to action required to be approved by the stockholders
or by the outstanding shares, the business and affairs of the corporation shall
be managed and all corporate powers shall be exercised by or under the direction
of the board of directors.

         3.2     NUMBER OF DIRECTORS

         The board of directors shall consist of nine (9) members. The number of
directors may be changed by an amendment to this bylaw, duly adopted by the
board of directors or by the stockholders, or by a duly adopted amendment to the
certificate of incorporation. Upon the closing of the first sale of the
corporation's common stock pursuant to a firmly underwritten registered public
offering (the "IPO"), the directors shall be divided into three classes, with
the term of office of the first class, which class shall initially consist of
three (3) directors, to expire at the first annual meeting of stockholders held
after the IPO; the term of office of the second class, which shall initially
consist of three (3) directors, 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 three (3) 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 held
after such election.

                                      -7-
<PAGE>   12


         No reduction of the authorized number of directors shall have the
effect of removing any director before that director's term of office expires.

         3.3     ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS

         Except as provided in Sections 3.2 and 3.4 of these amended and
restated bylaws, directors shall be elected at each annual meeting of
stockholders to hold office until the next annual meeting. Directors need not be
stockholders unless so required by the certificate of incorporation or these
amended and restated bylaws, wherein other qualifications for directors may be
prescribed. Each director, including a director elected to fill a vacancy, shall
hold office until his successor is elected and qualified or until his earlier
resignation or removal.

         Elections of directors need not be by written ballot.

         3.4     RESIGNATION AND VACANCIES

         Any director may resign at any time upon written notice to the
attention of the Secretary of the corporation. When one or more directors shall
resign from the board of directors, effective at a future date, a majority of
the directors then in office, including those who have so resigned, shall have
power to fill such vacancy or vacancies, the vote thereon to take effect when
such resignation or resignations shall become effective, and each director so
chosen shall hold office as provided in this section in the filling of other
vacancies.

         Unless otherwise provided in the certificate of incorporation or these
amended and restated bylaws:

                  (i) Vacancies and newly created directorships resulting from
any increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

                  (ii) Whenever the holders of any class or classes of stock or
series thereof are entitled to elect one or more directors by the certificate of
incorporation, vacancies and newly created directorships of such class or
classes or series may be filled by a majority of the directors elected by such
class or classes or series thereof then in office, or by a sole remaining
director so elected.

         If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these amended and restated
bylaws, or may apply to the Court of Chancery for a decree summarily ordering an
election as provided in Section 211 of the Delaware General Corporation Law.
                                      -8-

<PAGE>   13



        If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole board (as constituted immediately prior to any such increase), then
the Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten (10) percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by the provisions of Section 211 of the
Delaware General Corporation Law as far as applicable.

         3.5     PLACE OF MEETINGS; MEETINGS BY TELEPHONE

         The board of directors of the corporation may hold meetings, both
regular and special, either within or outside the State of Delaware.

         Unless otherwise restricted by the certificate of incorporation or
these amended and restated bylaws, members of the board of directors, or any
committee designated by the board of directors, may participate in a meeting of
such board of directors, 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 such participation in a meeting pursuant to
this section shall constitute presence in person at the meeting.

         3.6     REGULAR MEETINGS

         Regular meetings of the board of directors may be held without notice
at such time and at such place as shall from time to time be determined by the
board.

         3.7     SPECIAL MEETINGS; NOTICE

         Special meetings of the board of directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two (2) directors.

         Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally or by
telephone or by telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director. The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

         3.8     QUORUM

         At all meetings of the board of directors, a majority of the authorized
number of directors shall constitute a quorum for the transaction of business
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 statute, the certificate of incorporation, or
these amended and restated bylaws. If a quorum is not present at any meeting of
the board of directors, then the directors present thereat may adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum is present.

         A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

         3.9     WAIVER OF NOTICE

         Whenever notice is required to be given under any provision of the
Delaware General Corporation Law, the certificate of incorporation, or these
amended and restated bylaws, a written waiver thereof, signed by the person
entitled to notice, whether before or after the time stated therein, shall be
deemed equivalent to notice. Attendance of a person at a meeting shall
constitute a waiver of notice of such meeting, except when such person attends a
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the directors, or members of a committee of
directors, need be specified in any written waiver of notice unless so required
by the certificate of incorporation or these amended and restated bylaws.

         3.10     BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

         Unless otherwise restricted by the certificate of incorporation or
these amended and restated bylaws, any action required or permitted to be taken
at any meeting of the board of directors, or of any committee thereof may be
taken 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.

         3.11     FEES AND COMPENSATION OF DIRECTORS

         Unless otherwise restricted by the certificate of incorporation or
these amended and restated bylaws, the board of directors shall have the
authority to fix the compensation of directors.

         3.12     APPROVAL OF LOANS TO OFFICERS

        The corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee

                                      -10-


<PAGE>   15

who is a director of the corporation or its subsidiary, whenever, in the
judgment of the directors, such loan, guaranty or assistance may reasonably be
expected to benefit the corporation. The loan, guaranty or other assistance may
be with or without interest and may be unsecured, or secured in such manner as
the board of directors shall approve, including, without limitation, a pledge of
shares of stock of the corporation. Nothing contained in this section shall be
deemed to deny, limit or restrict the powers of guaranty or warranty of the
corporation at common law or under any statute.

         3.13     REMOVAL OF DIRECTORS

         Unless otherwise restricted by statute, by the certificate of
incorporation or by these amended and restated bylaws, any director or the
entire board of directors may be removed, with or without cause, by the holders
of a majority of the shares then entitled to vote at an election of directors;
provided, however, that, so long as stockholders of the corporation are entitled
to cumulative voting, if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against his removal
would be sufficient to elect such director if then cumulatively voted at an
election of the entire board of directors or, if there be classes of directors,
at an election of the class of directors of which such director is a part.

         No reduction of the authorized number of directors shall have the
effect of removing any director prior to the expiration of such director's term
of office.

                                   ARTICLE IV

                                   COMMITTEES

         4.1     COMMITTEES OF DIRECTORS

        The board of directors may, by resolution passed by a majority of the
whole board, designate one or more committees, with each committee to consist of
one or more of the directors of the corporation. The board may designate one or
more directors as alternate members of any committee, who may replace any absent
or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not such
member or members constitute a quorum, may unanimously appoint another member of
the board of directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the board of directors, or in the amended and restated bylaws of
the corporation, shall have and may exercise all the powers and authority of the
board of directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers that may require it; but no such committee shall have the power or
authority (i) approving or adopting or recommending to the stockholders, any
action or matter expressly required by the Delaware General Corporation Law to
be submitted to stockholders for approval or (ii) adopting, amending, or
repealing any amended and restated bylaws of the corporation; and, unless

                                      -11-
<PAGE>   16

the board resolution establishing the committee, the amended and restated bylaws
or the certificate of incorporation expressly so provide, no such committee
shall have the power or authority to declare a dividend, to authorize the
issuance of stock, or to adopt a certificate of ownership and merger pursuant to
Section 253 of the Delaware General Corporation Law.

         4.2     COMMITTEE MINUTES

         Each committee shall keep regular minutes of its meetings and report
the same to the board of directors when required.

taken in accordance with, the provisions of Article III of these amended and
restated bylaws, Section 3.5 (place of meetings and meetings by telephone),
Section 3.6 (regular meetings), Section 3.7 (special meetings and notice),
Section 3.8 (quorum), Section 3.9 (waiver of notice), and Section 3.10 (action
without a meeting), with such changes in the context of those amended and
restated bylaws as are necessary to substitute the committee and its members for
the board of directors and its members; provided, however, that the time of
regular meetings of committees may be determined either by resolution of the
board of directors or by resolution of the committee, that special meetings of
committees may also be called by resolution of the board of directors and that
notice of special meetings of committees shall also be given to all alternate
members, who shall have the right to attend all meetings of the committee. The
board of directors may adopt rules for the government of any committee not
inconsistent with the provisions of these amended and restated bylaws.

                                    ARTICLE V

                                    OFFICERS

necessary to make it effective. Any resignation is without prejudice to the
rights, if any, of the corporation under any contract to which the officer is a
party.

         Any vacancy occurring in any office of the corporation shall be filled
by the board of directors.

         5.5     CHAIRMAN OF THE BOARD

<PAGE>   20

such person directly or by any other person authorized to do so by proxy or

                                   ARTICLE VI

                                    INDEMNITY

         6.1     THIRD PARTY ACTIONS

         The corporation shall indemnify 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 (if such settlement is approved
in advance by the corporation, which approval shall not be unreasonably
withheld) 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 the person reasonably believed to be in or not
opposed to the best interest of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that the person's
conduct was unlawful.

         6.2     ACTIONS BY OR IN THE RIGHT OF THE CORPORATION

         The corporation shall 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 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


                                      -16-
<PAGE>   21

against expenses (including attorneys' fees) and amounts paid in settlement (if
such settlement is approved in advance by the corporation, which approval shall
not be unreasonably withheld) 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 manner such person 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 Delaware 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 Delaware Court of Chancery or such other court shall deem
proper. Notwithstanding any other provision of this Article VI, no person shall
be indemnified hereunder for any expenses or amounts paid in settlement with
respect to any action to recover short-swing profits under Section 16(b) of the
Securities Exchange Act of 1934, as amended.

         6.3     SUCCESSFUL DEFENSE

         To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Sections 6.1 and 6.2, or in defense of
any claim, issue or matter therein, such person shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by such
person in connection therewith.

         6.4     DETERMINATION OF CONDUCT

         Any indemnification under Sections 6.1 and 6.2 (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case
upon a determination that the 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 Sections 6.1 and 6.2. Such
determination shall be made (1) by the Board of Directors or the Executive
Committee by a majority vote of a quorum consisting of directors who were not
parties to such action, suit or proceeding or (2) if such quorum is not
obtainable or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders. Notwithstanding the foregoing, a director, officer, employee or
agent of the Corporation shall be entitled to contest any determination that the
director, officer, employee or agent has not met the applicable standard of
conduct set forth in Sections 6.1 and 6.2 by petitioning a court of competent
jurisdiction.

         6.5     PAYMENT OF EXPENSES IN ADVANCE

         Expenses incurred in defending a civil or criminal action, suit or
proceeding, by an individual who may be entitled to indemnification pursuant to
Section 6.1 or 6.2, shall be paid by the corporation in advance of the final
disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of the director, officer, employee or agent to repay such amount if
it

                                      -17-
<PAGE>   22

shall ultimately be determined that such person is not entitled to be
indemnified by the corporation as authorized in this Article VI.

         6.6     INDEMNITY NOT EXCLUSIVE

         The indemnification and advancement of expenses provided by or granted
pursuant to the other sections of this Article VI shall not be deemed exclusive
of any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any by-law, agreement, 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.

         6.7     INSURANCE INDEMNIFICATION

         The corporation shall have the 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 VI.

         6.8     THE CORPORATION

         For purposes of this Article VI, references to "the corporation" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, and employees or agents, so that
any person who is or was a director, officer, employee or agent of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under and subject to the provisions of this Article VI (including,
without limitation the provisions of Section 6.4) with respect to the resulting
or surviving corporation as such person would have with respect to such
constituent corporation if its separate existence had continued.

         6.9     EMPLOYEE BENEFIT PLANS

         For purposes of this Article VI, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner such person
reasonably believed to be in the interest of the participants and beneficiaries
of an employee

                                      -18-
<PAGE>   23

benefit plan shall be deemed to have acted in a manner "not opposed to the best
interests of the corporation" as referred to in this Article VI.

         6.10     CONTINUATION OF INDEMNIFICATION AND ADVANCEMENT OF EXPENSES

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



                                   ARTICLE VII

                               RECORDS AND REPORTS

         7.1     MAINTENANCE AND INSPECTION OF RECORDS

         The corporation shall, either at its principal executive officer or at
such place or places as designated by the board of directors, keep a record of
its stockholders listing their names and addresses and the number and class of
shares held by each stockholder, a copy of these amended and restated bylaws as
amended to date, accounting books, and other records.

         Any stockholder of record, in person or by attorney or other agent,
shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder. In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent so to act on
behalf of the stockholder. The demand under oath shall be directed to the
corporation at its registered office in Delaware or at its principal place of
business.

         The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, showing the address of each stockholder and the number of
shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at


                                      -19-
<PAGE>   24

the time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present.

         7.2     INSPECTION BY DIRECTORS

         Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his position as a director. The Court of Chancery
is hereby vested with the exclusive jurisdiction to determine whether a director
is entitled to the inspection sought. The Court may summarily order the
corporation to permit the director to inspect any and all books and records, the
stock ledger, and the stock list and to make copies or extracts therefrom. The
Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

         7.3     ANNUAL STATEMENT TO STOCKHOLDERS

         The board of directors shall present at each annual meeting, and at any
special meeting of the stockholders when called for by vote of the stockholders,
a full and clear statement of the business and condition of the corporation.


                                  ARTICLE VIII

                                 GENERAL MATTERS

         8.1     CHECKS

         From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

         8.2     EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS

         The board of directors, except as otherwise provided in these amended
and restated bylaws, may authorize any officer or officers, or agent or agents,
to enter into any contract or execute any instrument in the name of and on
behalf of the corporation; such authority may be general or confined to specific
instances. Unless so authorized or ratified by the board of directors or within
the agency power of an officer, no officer, agent or employee shall have any
power or authority to bind the corporation by any contract or engagement or to
pledge its credit or to render it liable for any purpose or for any amount.

         8.3     STOCK CERTIFICATES; PARTLY PAID SHARES

         The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the board of
directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the board of directors, or the president or vice-president, and by the chief
financial officer or an assistant treasurer, or the secretary or an assistant
secretary of such corporation representing the number of shares registered in
certificate form. Any or all of the signatures on the certificate may be a
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate has ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the corporation with the same effect as if such person were
such officer, transfer agent or registrar at the date of issue.

         The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

         8.4     SPECIAL DESIGNATION ON CERTIFICATES

         If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

         8.5     LOST CERTIFICATES

        Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time. The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate theretofore issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify it against any claim that may be made against it on
account of the alleged loss, theft or destruction of any such certificate or the
issuance of such new certificate or uncertificated shares.

         8.6     CONSTRUCTION; DEFINITIONS

         Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Delaware General Corporation Law shall
govern the construction of these amended and restated bylaws. Without limiting
the generality of this provision, the singular number includes the plural, the
plural number includes the singular, and the term "person" includes both a
corporation and a natural person.

         8.7     DIVIDENDS

         The directors of the corporation, subject to any restrictions contained
in (i) the Delaware General Corporation Law or (ii) the certificate of
incorporation, may declare and pay dividends upon the shares of its capital
stock. Dividends may be paid in cash, in property, or in shares of the
corporation's capital stock.

         The directors of the corporation may set apart out of any of the funds
of the corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

         8.8     FISCAL YEAR

         The fiscal year of the corporation shall be fixed by resolution of the
board of directors and may be changed by the board of directors.

         8.9     SEAL

         The corporation may adopt a corporate seal, which shall be adopted and
which may be altered by the board of directors, and may use the same by causing
it or a facsimile thereof to be impressed or affixed or in any other manner
reproduced.

         8.10     TRANSFER OF STOCK

         Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignation or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate, and record the transaction in its books.

         8.11     STOCK TRANSFER AGREEMENTS

         The corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the corporation to restrict the transfer of shares of stock of the corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the Delaware General Corporation Law.

         8.12     REGISTERED STOCKHOLDERS

         The corporation shall be entitled to recognize the exclusive right of a
person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                   ARTICLE IX

                                   AMENDMENTS

         The amended and restated bylaws of the corporation may be adopted,
amended or repealed by the stockholders entitled to vote; provided, however,
that the corporation may, in its certificate of incorporation, confer the power
to adopt, amend or repeal amended and restated bylaws upon the directors. The
fact that such power has been so conferred upon the directors shall not divest
the stockholders of the power, nor limit their power to adopt, amend or repeal
amended and restated bylaws.
