or summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock, provided 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, designations, preferences and
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.

                  Section 2. Any of or all the signatures on the certificate may
be facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have 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.

                                LOST CERTIFICATES

                  Section 3. The Board of Directors may direct a new certificate
or certificates to be issued in place of any certificate or certificates
theretofore issued by the corporation alleged to have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, stolen or destroyed. When authorizing such
issue of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his
legal representative, to advertise the same in such manner as it shall require
and/or to give the corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

                                TRANSFER OF STOCK

                  Section 4. 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 upon its books.

                               FIXING RECORD DATE

                  Section 5. In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholder or
any adjournment thereof, or 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. A
determination of stockholders of record entitled to notice of or


                                       10
<PAGE>   11
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.

                             REGISTERED STOCKHOLDERS

                  Section 6. 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, and to hold liable for calls and
assessments a 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 any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                   ARTICLE VII

                               GENERAL PROVISIONS

                                    DIVIDENDS

                  Section 1. Dividends upon the capital stock of the
corporation, subject to the provisions of the certificate of incorporation, if
any, may be declared by the Board of Directors at any regular or special
meeting, pursuant to law. Dividends may be paid in cash, in property, or in
shares of the capital stock, subject to the provisions of the certificate of
incorporation.

                  Section 2. Before payment of any dividend, there may be set
aside out of any funds of the corporation available for dividends such sum or
sums as the directors from time to time, in their absolute discretion, think
proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the corporation, or
for such other purposes as the directors shall think conducive to the interest
of the corporation, and the directors may modify or abolish any such reserve in
the manner in which it was created.

                                     CHECKS

                  Section 3. All checks or demands for money and notes of the
corporation shall be signed by such officer or officers or such other person or
persons as the Board of Directors may from time to time designate.

                                   FISCAL YEAR

                  Section 4. The fiscal year of the corporation shall be fixed
by resolution of the Board of Directors.

                                      SEAL

having inscribed thereon the name of the corporation, the year of its
organization and the words "Corporate Seal,



                                       11

Delaware." The seal may be used by causing it or a facsimile thereof to be
impressed or affixed or reproduced or otherwise.

                                 INDEMNIFICATION

                  Section 6. The corporation shall, to the fullest extent
authorized under the laws of the State of Delaware, as those laws may be amended
and supplemented from time to time, indemnify any director made, or threatened
to be made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being an agent of the corporation
or a predecessor corporation or, at the corporation's request, a director of
another corporation, provided, however, that the corporation shall indemnify any
such agent in connection with a proceeding initiated by such agent only if such
proceeding was authorized by the Board of Directors of the corporation. The
indemnification provided for in this Section 6 shall: (i) not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any bylaw, agreement or vote of stockholders or disinterested directors or
otherwise, both as to action in their official capacities and as to action in
another capacity while holding such office, (ii) continue as to a person who has
ceased to be a director, and (iii) inure to the benefit of the heirs, executors
and administrators of such a person. The corporation's obligation to provide
indemnification under this Section 6 shall be offset to the extent of any other
source of indemnification or any otherwise applicable insurance coverage under a
policy maintained by the corporation or any other person.

                  Expenses incurred by a director of the corporation in
defending a civil or criminal action, suit or proceeding by reason of the fact
that he is or was a director of the corporation (or was serving at the
corporation's request as a director or officer of another corporation) 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 such director to
repay such amount if it shall ultimately be determined that he is not entitled
to be indemnified by the corporation as authorized by relevant sections of the
General Corporation Law of Delaware. Notwithstanding the foregoing, the
corporation shall not be required to advance such expenses to an agent who is a
party to an action, suit or proceeding brought by the corporation and approved
by a majority of the Board of Directors of the corporation that alleges willful
misappropriation of corporate assets by such agent, disclosure of confidential
information in violation of such agent's fiduciary or contractual obligations to
the corporation or any other willful and deliberate breach in bad faith of such
agent's duty to the corporation or its stockholders.

                  The foregoing provisions of this Section 6 shall be deemed to
be a contract between the corporation and each director who serves in such
capacity at any time while this bylaw is in effect, and any repeal or
modification thereof shall not affect any rights or obligations then existing
with respect to any state of facts then or theretofore existing or any action,
suit or proceeding theretofore or thereafter brought based in whole or in part
upon any such state of facts.

                  The Board of Directors in its discretion shall have power on
behalf of the corporation to indemnify any person, other than a director, made a
party to any action, suit or


                                       12
<PAGE>   13
proceeding by reason of the fact that he, his testator or intestate, is or was
an officer or employee of the corporation.

                  To assure indemnification under this Section 6 of all
directors, officers and employees who are determined by the corporation or
otherwise to be or to have been "fiduciaries" of any employee benefit plan of
the corporation that may exist from time to time, Section 145 of the General
Corporation Law of Delaware shall, for the purposes of this Section 6, be
interpreted as follows: an "other enterprise" shall be deemed to include such an
employee benefit plan, including without limitation, any plan of the corporation
that is governed by the Act of Congress entitled "Employee Retirement Income
Security Act of 1974," as amended from time to time; the corporation shall be
deemed to have requested a person to serve an employee benefit plan where the
performance by such person of his duties to the corporation also imposes duties
on, or otherwise involves services by, such person to the plan or participants
or beneficiaries of the plan; excise taxes assessed on a person with respect to
an employee benefit plan pursuant to such Act of Congress shall be deemed
"fines."

                                  ARTICLE VIII

                                   AMENDMENTS

                  Section 1. These bylaws may be altered, amended or repealed or
new bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the certificate of
incorporation at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal or adoption of new
bylaws be contained in the notice of such special meeting. If the power to
adopt, amend or repeal bylaws is conferred upon the Board of Directors by the
certificate or incorporation it shall not divest or limit the power of the
stockholders to adopt, amend or repeal bylaws.
