                                   By-Laws of
                    Drexler Technology Corporation (Delaware)

                            As Adopted July 24, 1987
            And Incorporating All Amendments as of February 21, 1997


                               Article I. Offices

         I.1. Principal Office. The principal executive office and place of
business of the corporation (hereafter called the "principal office") is
fixed and located at:
                            1077 Independence Avenue
                             Mountain View, CA 94043

The Board of Directors shall have the authority from time to time to change the
principal office from one location to another by amending this Section 1.1.

         I.2. Registered Office. The registered office of the corporation in
Delaware is located as set forth in the Certificate of Incorporation. The Board
of Directors may by resolution change such location and shall then make
appropriate filings with the Delaware Secretary of State and the Office of the
Recorder for the county in which the new registered office is located.

         I.3. Other Offices. One or more branches or other subordinate offices
may at any time be fixed and located by the Board of Directors at such place or
places within or without the State of California as it deems appropriate.

                      Article II. Meetings of Stockholders

         II.1. Place of Meetings. Meetings of the stockholders shall be held at
any place within or outside the State of Delaware that may be designated by the
Board of Directors. If no such designation is made, the meetings shall be held
at the principal office of the corporation designated in Section 1.1 of these
By-Laws.

         II.2. Annual Meetings. The annual meeting of the stockholders shall be
held on the second Wednesday of September in each year, if not a legal holiday,
and if a legal holiday, then on the next succeeding business day, at the hour of
2:00 P.M., at which time the stockholders shall elect a Board of Directors and
transact such other business as may properly be brought before the meeting.

                  If the annual meeting of stockholders shall not be held on the
date above specified, the Board of Directors shall cause such a meeting to be
held as soon thereafter as convenient, and any business transacted or election
held at such meeting shall be as valid as if transacted or held at an annual
meeting on the date above specified.

         II.3. Special Meetings. Special meetings of the stockholders, for any
purpose or purposes whatsoever, may be called at any time by the Board of
Directors or by stockholders entitled to cast not less than ten percent (10%) of
the votes at such meeting.


<PAGE>   2




         II.4. Notice of Stockholders' Meetings. Whenever stockholders are
required or permitted to take any action at a meeting, a written notice of the
meeting shall be given not less than ten (10) (or if sent by third-class mail,
thirty (30)) nor more than sixty (60) days before the date of the meeting to
each stockholder entitled to vote thereat. Such notice shall state the place,
date and hour of the meeting and (1) in the case of a special meeting, the
general nature of the business to be transacted, and no other business may be
transacted, or (2) in the case of the annual meeting, those matters which the
Board of Directors, at the time of the mailing of the notice, intends to present
for action by the stockholders, but any proper matter may be presented by the
Board of Directors at the meeting for such action. The notice of any meeting at
which directors are to be elected shall include the names of nominees intended
at the time of the notice to be presented by the Board for election.

                  Notice of a stockholders' meeting shall be given either
personally or by first or third class mail or other means of written
communication, addressed to the stockholder at the address of such stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice; or if no such address appears or is
given, at the place where the principal office of the corporation is located.
The notice shall be deemed to have been given at the time when delivered
personally or deposited in the mail postage prepaid or sent by other means of
written communication. No notice need to be given to those stockholder specified
in Section 230 of the Law. An affidavit of the Secretary or an Assistant
Secretary or the transfer agent of the corporation that notice has been given
shall in the absence of fraud, be prima facie evidence of the facts stated
therein.

         II.5. Quorum. At a meeting of the stockholders, a majority of the
shares of the corporation entitled to vote, represented in person or by proxy,
shall constitute a quorum for the transaction of business. The affirmative vote
of a majority of the shares, present in person or represented by proxy at the
meeting and entitled to vote on the subject matter, at a duly held meeting at
which a quorum is present, shall be the act of the stockholders, unless the vote
of a greater number or voting by classes is required by the Law, or the
Certificate of Incorporation or By-Laws of this corporation. Stockholders
present at a valid meeting at which a quorum is initially present may continue
to do business until adjournment notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by a majority of the shares originally present at the
time the quorum was determined and which shares are entitled to vote on the
subject matter.

         II.6. Adjourned Meeting. Any annual or special stockholders' meeting
may be adjourned from time to time, even though a quorum is not present, by the
vote of the holders of a majority of the voting shares represented at the
meeting either in person or by proxy, provided that in the absence of a quorum,
no other business may be transacted at the meeting except as provided in Section
2.5 of these By-Laws.

                  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, any business may be transacted which 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.


<PAGE>   3




         II.7. Waiver or Consent by Stockholders. The transactions of any
meeting of stockholders, however called and noticed, and wherever held, are as
valid as though had at a meeting duly held after regular call and notice, if a
quorum is present either in person or by proxy, and if, either before or after
the meeting, each of the persons entitled to vote, not present in person or by
proxy, signs a written waiver of notice of the meeting. All such waivers shall
be filed with the corporate records or made a part of the minutes of the
meeting. Attendance of a person at a meeting shall constitute a waiver of notice
of and presence at such meeting, except when the person objects, 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 stockholders need be specified
in any written waiver of notice.

         II.8. Action Without Meeting. Any action which may be taken at any
annual or special meeting of stockholders may be taken without a meeting and
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 shares 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. Such written consent may be signed in counterparts and,
in order to be effective, shall bear the date of signature of each stockholder
who signs the consent and be delivered within sixty (60) days of the earliest
dated consent to the corporation's registered office in Delaware, its principal
place of business, or an officer or agent of the corporation having custody of
the book in which proceedings of meetings of stockholders are recorded. To be
effective, delivery made to the corporation's registered office shall only be by
hand or by certified or registered mail, return receipt requested; delivery to
the principal place of business or to an officer or agent of the corporation may
be made also by other means. 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.

                  Any stockholder giving a written consent, or the stockholder's
proxyholders, or a transferee of the shares or a personal representative of the
stockholder or their respective proxyholders, may revoke the consent by a
writing received by the corporation prior to the time that written consents of
the number of shares required to authorize the proposed action have been filed
with the Secretary of the corporation, but may not do so thereafter. Such
revocation is effective upon its receipt by the Secretary of the corporation.

         II.9. Record Date and Voting Rights. Except as otherwise provided by
law, only persons in whose names shares entitled to vote stand on the stock
records of the corporation at the close of business on the record date fixed by
the Board of Directors as provided in Section 5.1 for the determination of
stockholders of record shall be entitled to notice of and to vote at such
meeting of stockholders. If no record date is fixed, 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 business day next
preceding the day on which notice is given or, if notice is waived, at the close
of business on the business day next preceding the day on which the meeting is
held; the record date for determining stockholders entitled to give consent to
corporate action in writing without a meeting, when no prior action by the Board
is required, shall be the day on which the first written consent is given, and
if such Board action is


<PAGE>   4



required, shall be the day that the Board adopted a resolution taking such
action; and the record date for determining stockholders for any other purpose
shall be at the close of business on the day on which the Board adopts the
resolution relating thereto. Unless the Board of Directors chooses to fix a new
record date for an adjourned meeting, the record date for the adjourned meeting
shall be that of the original meeting.

                  Except as may be otherwise provided in the Certificate of
Incorporation, the holder of each outstanding share, regardless of class, shall
be entitled to one vote for each share held on each matter submitted to a vote
of stockholders. The voting of shares held in a fiduciary capacity, held of
record by two or more persons, or which are pledged or subject to a voting
agreement or trust shall be determined by and subject to Sections 217 and 218 of
the Law. Voting may be by voice or ballot, provided that any election of
directors must be by ballot upon the demand of any stockholder made at the
meeting and before the voting begins.

         II.10. Proxies. Every person entitled to vote shares may authorize
another person or persons to act by proxy with respect to such shares. All
proxies must be in writing and must be signed by the stockholder confirming the
proxy or his attorney-in-fact. No proxy shall be valid after the expiration of
three years from the date thereof unless otherwise provided in the proxy. Every
proxy continues in full force and effect until revoked by the person executing
it prior to the vote pursuant thereto, unless the proxy states that it is
irrevocable and if, and only so long as, it is coupled with an interest
sufficient in law to support an irrevocable proxy. Except for such irrevocable
proxies, such revocation may be effected by a writing delivered to the
corporation stating that the proxy is revoked or by a subsequent proxy executed
by the person executing the prior proxy and presented to the meeting, or as to
any meeting, by attendance at such meeting and voting in person by the person
executing the proxy. The dates contained on the forms of proxy presumptively
determine the order of execution, regardless of the postmark dates on the
envelopes in which they are mailed.

         II.11. Inspectors of Election. In advance of any meeting of
stockholders the Board of Directors may appoint inspectors of election to act at
the meeting and any adjournment thereof. If inspectors of election are not so
appointed, or if any persons so appointed fail to appear or refuse to act, the
chairman of any meeting of stockholders may, and on the request of any
stockholder or a stockholder's proxy shall, appoint inspectors of election (or
persons to replace those who so fail or refuse) at the meeting. The number of
inspectors shall be either one or three. If appointed at a meeting on the
request of one or more stockholders or proxies, the majority of shares
represented in person or by proxy shall determine whether one or three
inspectors are to be appointed. If there are three inspectors of election, the
decision, act or certificate of a majority is effective in all respects as the
decision, act or certificate of all.

                  The inspectors of election shall determine the number of
shares outstanding and the voting power of each, the shares represented at the
meeting, the existence of a quorum and the authenticity, validity and effect of
proxies, receive votes, ballots or consents, hear and determine all challenges
and questions in any way arising in connection with the right to vote, count and
tabulate all votes or consents, determine when the polls shall close, determine
the result and do such acts as may be proper to conduct the election or vote
with fairness to all stockholders.

         II.12. List of Stockholders. The Secretary shall prepare and make, at
least ten (10) days before every meeting of stockholders, a complete list of the
stockholders entitled to vote at said 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 opened 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)


<PAGE>   5



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 specified,at the place where the meeting is to be held. The list shall be
produced and kept at the time and place of meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

         II.13.  Nominations and Proposals.

                  (a) The Board of Directors of the Corporation may nominate
candidates for election as directors of the corporation and may propose such
other matters for approval of the stockholders as the Board deems necessary or
appropriate.

                  (b) No nominations for director of the corporation by any
person other than the Board of Directors shall be presented to any meeting of
stockholders unless the person making the nomination is a record stockholder and
shall have given a timely notice to the Secretary. To be timely, a stockholder's
notice shall be delivered to or mailed and received at the principal offices of
the corporation not less than 60 days nor more than 90 days prior to the
meeting; provided, however, that in the event that less than 60 days' notice or
prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholder to be timely must be so received not
later than the close of business on the 10th day following the day on which such
notice of the date of the meeting was mailed or such public disclosure was made
and provided further, that public disclosure shall hereby be deemed to have been
made of any annual meeting held on the date specified in these By-Laws. Such
notice shall (i) set forth the name and address of the person advancing such
nomination and the nominee, together with such information concerning the person
making the nomination and the nominee as would be required by the appropriate
Rules and Regulations of the Securities and Exchange Commission to be included
in a proxy statement soliciting proxies for the election of such nominee, and
(ii) shall include the duly executed written consent of such nominee to serve as
director if elected.

                  (c) No proposal by any person other than the Board of
Directors shall be submitted for the approval of the stockholders at any regular
or special meeting of the stockholders of the corporation unless the person
advancing such proposal shall have given a timely notice to the Secretary. To be
timely, a stockholder's notice shall be delivered to or mailed and received at
the principal offices of the corporation not less than 60 days nor more than 90
days prior to the meeting; provided, however, that in the event that less than
60 days' notice or prior public disclosure of the date of the meeting is given
or made to stockholders, notice by the stockholder to be timely must be so
received not later than the close of business on the 10th day following the day
on which such notice of the date of the meeting was mailed or such public
disclosure was made and provided further, that public disclosure shall be deemed
to have been made of any annual meeting held on the date specified in these
By-Laws. Such notice shall set forth the name and address of the person
advancing the proposal, any material interest of such person in the proposal,
and such other information concerning the person making such proposal and the
proposal itself as would be required by the appropriate Rules and Regulations of
the Securities and Exchange Commission to be included in a proxy statement
soliciting proxies for the proposal.

                       Article III. Directors; Management

         III.1. Powers. Subject to any provisions of the Certificate of
Incorporation and these By-Laws of this corporation and of the Law limiting the
powers of the Board of Directors or reserving powers to the stockholders, the
Board shall, directly or by delegation, manage the business and affairs of the
corporation and exercise all corporate powers permitted by law.


<PAGE>   6




         III.2. Number and Qualification of Directors. The authorized number of
directors shall be three (3), unless and until changed by a proper amendment to
this Section 3.2. A reduction in the authorized number of directors shall not
remove any director prior to the expiration of such director's term of office.
Directors need not be stockholders of the corporation.

         III.3. Election and Term of Office. The directors shall be elected
annually by the stockholders at the annual meeting of the stockholders;
provided, that if for any reason, said annual meeting or an adjournment thereof
is not held or the directors are not elected thereat, then the directors may be
elected at any special meeting of the stockholders called and held for that
purpose. The term of office of the directors shall, except as provided in
Section 3.4, begin immediately after their election and shall continue until
their respective successors are elected and qualified or until earlier
resignation or removal.

         III.4. Removal of Directors. A director may be removed from office by
the Board of Directors if he is declared of unsound mind by an order of court or
convicted of a felony. Any or all of the directors may be removed from office
with or without cause by a vote of stockholders holding a majority of the
outstanding shares entitled to vote at an election of directors.

         III.5. Vacancies. A vacancy or vacancies on the Board of Directors
shall exist on the death, resignation, or removal of any director, or if the
authorized number of directors is increased or the stockholders fail to elect
the full authorized number of directors. Any director may resign by giving
written notice to the Chairman of the Board, the President, the Secretary or the
Board of Directors of the corporation, which resignation shall be effective upon
the giving of such notice, unless the notice specifies a later time for the
effectiveness of such resignation.

                  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors may be filled by a majority of
the directors then in office, although less than a quorum, or by a sole
remaining director. When one or more directors shall resign from the Board,
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.

                  If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole Board (as constituted immediately prior to any such increase), the
Court of Chancery may, upon application of any stockholder or stockholders
holding at least 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 Section 211 of the Law as far as applicable.
Otherwise, the stockholders shall not be entitled to fill a vacancy or newly
created directorship except at an annual meeting or at a special meeting called
pursuant to Section 2.3 for such purpose. Notwithstanding the foregoing, 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
Certificate of Incorporation or the bylaws, or may apply to the Court of
Chancery for a decree summarily ordering an election as provided in Section 211
of the Law.

         III.6.  Place of Meetings.  Regular and special meetings of the Board
of Directors shall be held at any place within or outside the State of


<PAGE>   7



Delaware that is designated by resolution of the Board or, either before or
after the meeting, consented to in writing by all the Board members. If the
place of a regular or special meeting is not fixed by resolution or written
consents of the Board, it shall be held at the corporation's principal office.

         III.7.  Organizational Meetings.  Immediately following each annual
stockholders' meeting, the Board of Directors shall hold an organizational
meeting to organize, elect officers, and transact other business.  Notice
of this meeting shall not be required.

         III.8. Other Regular Meetings. The Board of Directors may, by
resolution, fix any time, date and place for other regular meetings of the Board
of Directors; provided, however, that any director not present at the meeting at
which such resolution was adopted receives notice of the adoption of such
resolution and the time and place of such meetings prior to the first regular
meeting held pursuant to such resolution. Such notice of the adoption of the
resolution must comply with the notice provisions of Section 3.9 of these
By-Laws as if the first regular meeting were a special meeting. After the first
regular meeting held pursuant to such resolution, no notice of regular meetings
held pursuant to this paragraph and such resolution shall be required.

         III.9.  Special Meetings.

                  (a) Special meetings of the Board of Directors for any purpose
or purposes may be called at any time or place by the Chairman of the Board, by
the President, or if both the Chairman of the Board and the President are
absent, are unable or refuse to act, by any Vice President, or by any two
directors.

                  (b)  Notice of the time and place of special meetings shall be
given in any one of the following manners:

                       (1) if delivered in person or by telephone, such notice
shall be delivered at least forty-eight (48) hours prior to the time the meeting
is to be held. Such notice may be communicated either to the director or to a
person at the home or business of the director when the person delivering the
notice has reason to believe such person will promptly communicate it to the
director. Such notice shall be considered delivered when the person noticing the
meeting believes in good faith that the notified person has heard and
acknowledged the notice;

                       (2) if delivered by telegram, such notice shall be
delivered to a common carrier, charges prepaid, for transmission to the director
at least forty-eight (48) hours prior to the time the meeting is to be held.
Delivery to a common carrier shall be due and legal notice to such director;

                       (3) if delivered by overnight courier service, including
without limitation such services as Express Mail and Federal Express, such
notice shall be delivered to such courier service, charges prepaid, for delivery
to the director no later than two days prior to the day upon which the meeting
is to be held. Delivery to a courier service shall be due and legal notice to
such director;

                       (4) if delivered by facsimile transmission, such notice
shall be either delivered to a common carrier, charges prepaid, for transmission
to the director or transmitted by or under the direction of the person giving
notice to the director at least forty-eight (48) hours prior to the time the
meeting is to be held. Delivery to a common carrier or transmission of a
facsimile shall be due and legal notice to such director;

                       (5) if delivered by first-class mail, such notice shall

<PAGE>   8



days prior to the date of the meeting to be held.  Deposit in the U.S. mail
shall be due and legal notice to such director.

                  The notice need not specify the place of the meeting if the
meeting is to be held at the principal office of the corporation.

         III.10. Quorum. A majority of the authorized number of directors, but
in no event less than two (2) (unless the authorized number of directors is one
(1)), shall constitute a quorum for the transaction of business, except to
adjourn a meeting under Section 3.12. Every act done or decision made by a
majority of the directors present at a meeting at which a quorum is present
shall be regarded as the act of the Board of Directors, unless the vote of a
greater number is required by law, the Certificate of Incorporation, or these
By-Laws. 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 a majority of the required quorum for such meeting.

         III.11. Contents of Notice and Waiver of Notice. Neither the business
to be transacted at, nor the purposes of, any regular or special Board meeting
need be specified in the notice or waiver of notice of the meeting. Notice of a
meeting need not be given to any director who signs a waiver of notice of the
meeting either before or after the meeting, or who attends the meeting without
protesting, prior thereto or at its commencement, the lack of notice to said
director. All such waivers shall be filed with the corporate records or made a
part of the minutes of the meeting.

         III.12.  Adjournment.  A majority of the directors present, whether
or not a quorum is present, may adjourn any meeting to another time and
place.

         III.13. Notice of Adjournment. Notice of the time and place of holding
an adjourned meeting need not be given to absent directors if the time and place
are fixed at the meeting being adjourned, except that if the meeting is
adjourned for more than twenty-four (24) hours such notice shall be given prior
to the adjourned meeting to the directors who were not present at the time of
the adjournment.

         III.14. Telephone Participation. Members of the Board of Directors may
participate in a meeting through use of conference telephone or similar
communications equipment, so long as all members participating in such meetings
can hear one another. Such participation constitutes presence in person at such
meeting.

         III.15. Action Without Meeting. The Board of Directors may take any
action without a meeting that may be required or permitted to be taken by the
Board at a meeting, if all members of the Board individually or collectively
consent in writing to the action. The written consent or consents shall be filed
in the minutes of the proceedings of the Board. Such action by written consent
shall have the same effect as a unanimous vote of directors.

         III.16. Fees and Compensation. Directors and members of committees
shall receive neither compensation for their services nor reimbursement for
their expenses unless these payments are fixed by resolution of the Board of
Directors.

         III.17. Certain Corporate Loans and Guaranties. The corporation may
make loans of money or property to, or guarantee the obligations of, or
otherwise assist any officer or other employee of the corporation or of its
subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, or adopt an employee benefit plan or plans
authorizing such loans or guaranties, upon the approval of the Board of


<PAGE>   9



Directors alone if the Board of Directors determines that such a loan or
guaranty or plan may reasonably be expected to benefit the corporation.

                              Article IV. Officers

         IV.1. Officers. The officers of the corporation shall be a President, a
Secretary, and a Treasurer. The corporation may also have, at the discretion of
the Board of Directors, a Chairman of the Board, one or more Vice Presidents,
one or more Assistant Secretaries, one or more Assistant Treasurers, and any
other officers who may be appointed under Section 4.3 of these By-Laws. Any two
or more offices, except those of President and Secretary, may be held by the
same person.

         IV.2. Election. The officers of the corporation, except those appointed
under Section 4.3 of these By-Laws, shall be chosen annually by the Board of
Directors, and each shall hold his office at the pleasure of the Board of
Directors until he resigns or is removed or otherwise disqualified to serve, or
his successor is elected and qualified.

         IV.3. Subordinate Officers. The Board of Directors may appoint, and may
authorize the President to appoint, any other officers that the business of the
corporation may require, each of whom shall hold office for the period, have the
authority, and perform the duties specified in the By-Laws or by the Board of
Directors.

         IV.4. Removal and Resignation. Any officer may be removed with or
without cause either by the Board of Directors at any regular or special Board
meeting or, except for an officer chosen by the Board, by an officer on whom the
power of removal may be conferred by the Board.

                  Any officer may resign at any time by giving written notice to
the Board, the President, or the Secretary of the corporation. An officer's
resignation shall take effect when it is received or at any later time specified
in the resignation. Unless the resignation specifies otherwise, its acceptance
by the corporation shall not be necessary to make it effective.

         IV.5.  Vacancies.  A vacancy in any office because of death,
resignation, removal, disqualification, or any other cause shall be filled
in the manner prescribed in these By-Laws for regular appointments to the
office.

   
         IV.6. Chairman of the Board. The Chairman shall be the corporation's
chief executive officer and general manager and shall, subject to the control of
the Board, have general supervision, direction and control over the
corporation's business and officers. This officer shall have the general powers
and duties of management usually vested in a corporation's chief executive
officer; shall have any other powers and duties that are prescribed by the Board
or these By-Laws; and shall be primarily responsible for carrying out all orders
and resolutions of the Board.

         The Chairman shall also preside as chairman at all meetings of the
directors and stockholders.
    
   
         IV.7. President. The President shall be the corporation's chief
operating officer with such responsibilities and authority as the Chairman shall
delegate. If the Chairman is unreachable in the event of an emergency, or is
disabled or dies, the President shall so notify the Board and, subject to
supervision by the Board, shall temporarily perform such duties of the Chairman
as are appropriate in the circumstances. When so acting temporarily, the
President shall have all the powers of the Chairman, subject to such limitations
thereon as may be imposed by the Board.
    


<PAGE>   10




         IV.8. Vice Presidents. If the President is absent or is unable or
refuses to act, the Vice Presidents in order of their rank as fixed by the Board
of Directors or, if not ranked, the Vice President designated by the Board,
shall perform all the duties of the President, and when so acting shall have all
the powers of, and be subject to all the restrictions on, the President. Each
Vice President shall have any other powers and perform any other duties that are
prescribed for him by the Board or the By-Laws.

   
         IV.8A. Executive Vice President. The Executive Vice President shall
have such management responsibilities and authority, particularly with respect
to manufacturing facilities, as the Chairman shall delegate. This officer shall
also be the first in rank of the Vice Presidents, such that if the President is
absent or is unable or refuses to act, the Executive Vice President shall be the
next in succession to perform the duties of the President.
    

         IV.9. Secretary. The Secretary shall keep or cause to be kept, and be
available at the principal office and any other place that the Board of
Directors specifies, a book of minutes of all directors' and stockholders'
meetings. The minutes of each meeting shall state the time and place that it was
held, whether it was regular or special, if a special meeting, how it was
authorized, the notice given, the names of those present or represented at
stockholders' meetings, and the proceedings of the meetings. A similar minute
book shall be kept for any committees, if required by the Board.

                  The Secretary shall keep, or cause to be kept, at the
principal office or at the office of the corporation's transfer agent, a share
register, or a duplicate share register, showing the stockholders' names and
addresses, the number and classes of shares held by each, the number and date of
each certificate issued for these shares, and the number and date of
cancellation of each certificate surrendered for cancellation.

                  The Secretary shall give, or cause to be given, notice of all

of account shall at all reasonable times be open to inspection by any director.

                  The corporation's chief financial officer shall deposit all

the depositories designated by the Board of Directors. He shall disburse the
corporation's funds as ordered by the Board of Directors; shall render to the
President and directors, whenever they request it, an account of all his
transactions as the corporation's chief financial officer and of the
corporation's financial condition; and shall have any other powers and perform
any other duties that are prescribed by the Board of Directors or the By-Laws.

                  If required by the Board of Directors, the corporation's chief

surety or sureties specified by the Board for faithful performance of the duties
of his office and for restoration to the corporation of all its books, papers,
vouchers, money, and other property of every kind in his


<PAGE>   11



possession or under his control on his death, resignation, retirement, or
removal from office.

         4.11 Representation of Shares of Other Corporations. The Chairman of
the Board, the President, any Vice President, the Treasurer, the Secretary or
Assistant Secretary of this corporation, or any other person authorized by the
Board of Directors or the President or a Vice President, is authorized to vote,
represent, and exercise on behalf of this corporation all rights incident to any
and all shares of any other corporation or corporations standing in the name of
this corporation. The authority granted herein may be exercised either by such
person directly or by any other person authorized to do so by proxy or power of
attorney duly executed by such person having the authority.

         4.12 Authority and Duties of Officers. In addition to the foregoing
authority and duties, all officers of the corporation shall respectively have
such authority and perform such duties in the management of the business of the
corporation as may be designated from time to time by the Board of Directors or
the stockholders.

                      Article V. General Corporate Matters

         V.1. Record Date and Closing of Stockbooks. The Board of Directors may
fix a time in the future as a record date for determining stockholders entitled
to notice of and to vote at any stockholders' meeting, entitled to consent to
corporate action, 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, commission or exchange of stock or for the purpose of any
other lawful action. The record date for determining the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof, shall not, however, be more than sixty (60) nor less than ten (10) days
prior to the date of such meeting. The record date for determining the
stockholders entitled to consent to corporate action in writing without a
meeting shall not be more than ten (10) days after the date upon which the
resolution fixing the record date is adopted by the board of directors. The
record date for determining the stockholders entitled to receive payments of any
dividend or other distribution or allotment of any rights or for determining the
stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
shall not be more than sixty (60) days prior to such action. If a record date is
fixed for a particular meeting or event, only stockholders of record on that
date are entitled to notice and to vote and to receive the dividend,
distribution, or allotment of rights, or to exercise the rights, as the case may
be, notwithstanding any transfer of any shares on the books of the corporation
after the record date.

         V.2. Corporate Records and Inspection by Stockholders and Directors.
The corporation shall, either at its principal office 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 bylaws as amended to date, accounting books,
books of minutes of meetings or consents of the Board of Directors, committees
thereof, and stockholders and other records. Any stockholder of record, in
person or by attorney or other agent, shall, upon five days' prior 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 to so act on behalf of the
stockholder. The demand


<PAGE>   12



under oath shall be directed to the corporation at its registered office in
Delaware or at its principal place of business.

                  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.

         V.3. Checks, Drafts, Evidences of Indebtedness. All checks, drafts, or
other orders for payment of money, notes, and all mortgages, or other evidences
of indebtedness, issued in the name of or payable to the corporation, and all
assignments and endorsements of the foregoing, shall be signed or endorsed by
the person or persons and in the manner specified by the Board of Directors.

         V.4. Corporate Contracts and Instruments; How Executed. Except as
otherwise provided in the By-Laws, officers, agents or employees must be
authorized by the Board of Directors to enter into any contract or execute any
instrument in the corporation's name and on its behalf. This authority may be
general or confined to specific instances.

         V.5. Stock Certificates. One or more certificates for shares of the
corporation's capital stock shall be issued to each stockholder for any of his
shares that are fully paid up. The corporate seal or its facsimile may be fixed
on certificates. All certificates shall be signed by the Chairman of the Board,
President, or a Vice President and the Secretary, Treasurer, or an Assistant
Secretary. Any or all of the signatures on the certificate may be facsimile
signatures. 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 he were such
officer, transfer agent or registrar at the date of issue.

         V.6. Lost Certificates. No new share certificate that replaces an old
one shall be issued unless the old one is surrendered and cancelled at the same
time; provided, however, that if any share certificate is lost, stolen,
mutilated, or destroyed, the President and Secretary may cause to be issued a
new certificate replacing the old one on any terms and conditions, including a
bond or other reasonable arrangement for indemnification of the corporation,
that the President may specify.

         V.7. Construction; Definitions. Unless the context requires otherwise,
the general provisions, rules of construction, and definitions in the Delaware
General Corporation Law (heretofore and hereafter the "Law") shall govern the
construction of these By-Laws. 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.

                             Article VI. Amendments

         By-Laws may be adopted, amended or repealed by either the affirmative
vote or written consent of stockholders owning a majority of the outstanding
shares entitled to vote or by the Board of Directors.






<PAGE>   13



                      Article VII. Committees of the Board

         The Board of Directors may, by resolution adopted by a majority of the
authorized number of directors, designate one or more committees, each
consisting of one or more directors, to serve at the pleasure of the Board and
with such authority and organization as the Board may from time to time
determine. The Board may designate one or more directors as alternate members of
any committee, who may replace any absent member at any meeting of the
committee. The appointment of members or alternate members of a committee
requires the vote of a majority of the authorized number of directors. In the
absence or disqualification of a member of a committee, the member or members
thereof present at any meeting and not disqualified for voting, whether or not
he or they 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, shall have and may exercise 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 to (i) amend the Certificate of Incorporation (except that a committee
may, to the extent authorized in the resolution or resolutions providing for the
issuance of shares of stock adopted by the Board of Directors as provided in
Section 151(a) of the Law, fix the designations and any of the preferences or
rights of such shares relating to dividends, redemption, dissolution, any
distribution of assets of the corporation or the conversion into, or the
exchange of such shares for, share of any other class or classes or any other
series of the same or any other class or classes of stock of the corporation or
fix the number of shares of any series of stock or authorize the increase or
decrease of the shares of any series), (ii) adopt an agreement of merger or
consolidation under Sections 251 or 252 of the Law, (iii) recommend to the
stockholders the sale, lease or exchange of all or substantially all of the
corporation's property and assets, (iv) recommend to the stockholders a
dissolution of the corporation or a revocation of a dissolution, or (v) amend
the By-Laws of the corporation; and, unless the Board resolution establishing
the committee, the By-Laws 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 Law.

                  The Board shall designate a chairman for each committee who
shall have the sole power to call any committee meeting other than a meeting set
by the Board. Each committee shall keep regular minutes of its meetings and
report the same to the Board of Directors when required.

                  Meetings and actions of committees shall be governed by, and
held and taken in accordance with, the provisions of the following sections of
Article III of these By-Laws, Section 3.6 (place of meetings, Section 3.8
(regular meetings), Section 3.9 (special meetings), Section 3.10 (quorum),
Section 3.11 (contents of notice and waiver of notice), Section 3.12
(adjournment), Section 3.13 (notice of adjournment), Section 3.14 (telephone
participation), and Section 3.15 (action without a meeting), with such changes
in the context of those By-Laws 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 By-Laws.

                          ARTICLE VIII. Indemnification

         VIII.1. Action, Etc. Other Than 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,
suit or proceeding or investigation, whether civil, criminal, administrative, or
investigative, and whether external or internal to the corporation (other than a
judicial action or suit brought by or in the right of the corporation), by
reason of the fact that he or she is or was a director or officer of the
corporation, or that he or she is or was serving at the request of the
corporation as a director, officer, employee, trustee, or agent of another
corporation, partnership, joint venture, trust or other enterprise (all such
persons being referred to hereafter as an "Agent"), against expenses (including
attorneys' fees), judgments, fines and amounts paid or to be paid in settlement
(if such settlement is approved by the corporation, which approval shall not be
unreasonably withheld or delayed) actually and reasonably incurred by him or her
in connection with such action, suit or proceeding, or any appeal therein, if
the Agent acted in good faith and in a manner he or she 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
conduct was unlawful. The termination of any action, suit or proceeding --
whether 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 or she reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, that such person had
reasonable cause to believe that his or her conduct was unlawful.

         VIII.2. Action, Etc., 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 judicial action or suit
brought by or in the right of the corporation to procure a judgment in its favor
by reason of the fact that he or she is or was an Agent (as defined above)
against expenses (including attorneys' fees) actually and reasonably incurred by
him or her in connection with the defense, settlement or appeal of such action
or suit if he or she acted in good faith and in a manner he or she 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 or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or other such court shall deem proper.

         VIII.3. Determination of Right of Indemnification. Any indemnification
under Sections 8.1 or 8.2 above (unless ordered by a court) shall be made by the
corporation only as authorized in the specific case upon a determination that
indemnification of the Agent is proper in the circumstances because he or she
has met the applicable standard of conduct set forth in Sections 8.1 and/or 8.2.
Such determination shall be made (1) by the Board of Directors by a majority
vote of a quorum consisting of Directors who were not parties to such action,
suit or proceeding, or (2) if such a quorum is not obtainable, or if such a
quorum is obtainable and so directs, by independent legal counsel (chosen either
jointly by the corporation and Agent or else by counsel to the corporation) in a
written opinion, or (3) by the stockholders.

         VIII.4.  Indemnification Against Expenses of Successful Party.
Notwithstanding the other provisions of this Article VIII, to the extent
that an Agent has been successful on the merits or otherwise, including,


<PAGE>   15



without limitation, the dismissal of an action without prejudice or the
settlement of an action without admission of liability, in defense of any claim,
issue, or matter therein, or an appeal from any such proceeding, action, or
claim or matter, such Agent shall be indemnified against all expenses incurred
in connection therewith.

         VIII.5. Advances of Expenses. Except as listed by Section 8.6, costs,
charges and expenses (including attorneys' fees) incurred in any action, suit,
proceeding or investigation or any appeal therefrom shall be paid by the
corporation in advance of the final disposition of such matter, if the Agent
shall undertake to repay such amount in the event that it is ultimately
determined, as provided herein, that such person is not entitled to
indemnification.

         VIII.6. Right of Agent to Indemnification Upon Application; Procedure
Upon Application. Any indemnification provided for in Sections 8.1, 8.2, or 8.4
shall be made no later than six (6) months after the corporation is given notice
of request by Agent, provided that such request is made after final
adjudication, dismissal, or settlement unless an appeal is filed, in which case
the request is made after the appeal is resolved. Upon such notice, the
corporation shall within two (2) weeks call a Board of Directors meeting to be
held within two (2) months of such notice to make a determination as to whether
the Agent has met the applicable standard of conduct. The corporation shall
retain (at the corporation's expense) independent legal counsel chosen either
jointly by the corporation and Agent or else by corporation counsel within two
(2) weeks to make such determination, if at such meeting a quorum consisting of
directors who were not parties to the relevant action, suit, or proceeding is
not obtainable, or if obtainable such quorum refuses to make such determination,
but so directs the corporation. If such legal counsel is not so retained or does
not make such determination within six (6) weeks, then the Board of Directors
shall cause a stockholders meeting to be held within two (2) months to make such
a determination.

                  If a claim under these By-Laws, under any statute, under any
provision of any agreement with the corporation, or under the corporation's
Certificate of Incorporation providing for indemnification or advance of
expenses, is not paid in full by the corporation within sixty (60) days in case
of indemnification and twenty (20) days in case of advance of expenses after
notice of a request for payment thereof has been given to the corporation by
Agent, Agent may, but need not, at any time thereafter bring an action against
the corporation to recover the unpaid amount of the claim or the expense advance
and, if successful, Agent shall also be entitled to be paid for the expenses
(including attorneys' fee) of bringing such action. It shall be a defense to any
such action (other than an action brought to enforce a claim for expenses
incurred in connection with any action, suit or proceeding in advance of its
final disposition) that Agent has not met the standards of conduct which make it
permissible under applicable law for the corporation to indemnify Agent for the
amount claimed, and Agent shall be entitled to receive interim payment of
expenses pursuant to Section 8.5 unless and until such defense may be finally
adjudicated by court order or judgment from which no further right of appeal
exists. Neither the failure of the corporation (including its Board of
Directors, any committee or subgroup of the Board of Directors, independent
legal counsel, or its stockholders) to have made a determination that
indemnification of Agent is proper in the circumstances because Agent has met
the applicable standard of conduct required by applicable law, nor an actual
determination by the corporation (including its Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its stockholders) that Agent has not met such applicable standard of conduct,
shall create a presumption that Indemnitee has or has not met the applicable
standard of conduct.

         VIII.7.  Other Rights and Remedies.  The indemnification provided by
this Article shall not be deemed exclusive of, and shall not affect, any


<PAGE>   16



other rights to which an Agent seeking indemnification may be entitled under any
law, other provision of these By-Laws, the corporation's Certificate of
Incorporation, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his or her official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be an Agent and shall inure to the benefit of the heirs,
executors, and administrators of such a person. All right to indemnification
under this Article shall be deemed to be provided by a contract between the
corporation and the Agent who serves in such capacity at any time these By-Laws
and other relevant provisions of the general corporation law and other
applicable law, if any, are in effect. Any repeal or modification thereof shall
not affect any rights or obligations then existing. In addition, notwithstanding
any other provisions of these ByLaws, the corporation hereby agrees to indemnify
the Agent to the fullest extent permitted by law, regardless of whether such
indemnification is authorized by any other provision of these By-Laws by the
corporation's Certificate of Incorporation, by agreement with the corporation,
or by statute.

         VIII.8. Insurance. Upon resolution passed by the Board of Directors,
the corporation may purchase and maintain insurance on behalf of any person who
is or was an Agent against any liability asserted against such person and
incurred by him or her in any such capacity, or arising out of his or her 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.

         VIII.9. Optional Means of Assuring Payment. Upon request by an Agent
certifying that the Agent has reasonable grounds to believe the Agent may be
made a party to a proceeding for which the Agent may be entitled to be
indemnified under this Article VIII, the corporation may but is not required to
create a trust fund, grant a security interest or use other means (including,
without limitation, a letter of credit) to ensure the payment of such sums as
may become necessary to effect indemnification as provided herein.

         VIII.10. Constituent Corporations. For the purposes of this Article,
references to "the corporation" include all constituent corporations absorbed in
a consolidation or merger as well as the resulting or surviving corporation, so
that any person who is or was a director, officer, employee, or trustee of such
a constituent corporation or who, being or having been such a director, officer,
employee or trustee, is or was serving at the request of such constituent
corporation as a director, officer, employee, trustee of another corporation,
partnership, joint venture, trust or other enterprise shall stand in the same
position under the provisions of this Article with respect to the resulting or
surviving corporation as such person would if he or she had served the resulting
or surviving corporation in the same capacity.

         VIII.11. Other Enterprises, Fines, and Serving at Corporation's
Request. For purposes of this Article, references to "other enterprise" in
Sections 8.1 and 8.10 shall include employee benefit plans; references to
"fines" shall include any excise taxes assessed on a person with respect to any
employee benefit plan; and references to "serving at the request of the
corporation" shall include any service by Agent as director, officer, employee,
trustee, or agent of the corporation which imposes duties on, or involves
services by, such Agent with respect to any employee benefit plan, its
participants, or beneficiaries; and a person who acted in good faith and in a
manner he or she reasonably believed to be in the interest of the participants
and beneficiaries of an employee 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.

         VIII.12.  Savings Clause.  If this Article or any portion thereof
shall be invalidated on any ground by any court of competent jurisdiction,


<PAGE>   17


then the corporation shall nevertheless indemnify each Agent as to expenses
(including attorneys' fees), judgments, fines, and amounts paid in settlement
with respect to any action, suit, appeal, proceeding, or investigation, whether
civil, criminal, or administrative, and whether internal or external, including
a grand jury proceeding and an action or suit brought by or in the right of the
corporation, to the full extent permitted by any applicable portion of this
Article that shall not have been invalidated, or by any other applicable law.

         VIII.13. Employees or Agents. The corporation may, by resolution of the
Board of Directors, grant an agent or employee of the corporation who is not an
officer or director of the corporation and therefore not an Agent, the rights of
an Agent under this Article VIII.
