                               SECTION 1. OFFICES

         The principal office of the corporation shall be located at its
principal place of business or such other place as the Board of Directors
("Board") may designate. The corporation may have such other offices, either
within or without the State of Delaware, as the Board may designate or as the
business of the corporation may require from time to time.

                             SECTION 2. STOCKHOLDERS

         2.1      ANNUAL MEETING.

         The annual meeting of the stockholders shall be held on such date and
at such place and hour as shall be fixed by the Board and designated in the
notice of such meeting or waiver of notice thereof.

         2.2      SPECIAL MEETINGS.

         The Chairman of the Board, the President, the Secretary, the Board or
the holders of not less than 20% of all the outstanding shares of the
corporation entitled to vote at the meeting, may call special meetings of the
stockholders for any purpose.

         2.3      PLACE OF MEETING.

         All meetings shall be held at the principal office of the corporation
or at such other place within or without the State of Delaware designated by the
Board, by any persons entitled to call a meeting hereunder or in a waiver of
notice signed by all of the stockholders entitled to notice of the meeting.

         2.4      NOTICE OF MEETING.

         The Chairman of the Board, the President, the Secretary, the Board, or
stockholders calling an annual or special meeting of stockholders as provided
for herein, shall cause to be delivered to each stockholder entitled to notice
of or to



vote at the meeting either personally or by mail, not less than ten nor more
than sixty days before the meeting, written notice stating the place, day and
hour of the meeting and, in the case of a special meeting, the purpose or
purposes for which the meeting is called. At any time, upon written request of
the holders of not less than the number of outstanding shares of the corporation
specified in subsection 2.2 and entitled to vote at the meeting, it shall be the
duty of the Secretary to give notice of a special meeting of stockholders to be
held on such date and at such place and hour as the Secretary may fix, not less
than ten nor more than thirty-five days after receipt of said request, and if
the Secretary shall neglect or refuse to issue such notice, the person making
the request may do so and may fix the date for such meeting. If such notice is
mailed, it shall be deemed delivered when deposited in the official government
mail properly addressed to the stockholder at his or her address as it appears
on the stock transfer books of the corporation with postage prepaid. If the
notice is telegraphed, it shall be deemed delivered when the content of the
telegram is delivered to the telegraph company.

         2.5      WAIVER OF NOTICE.

                  2.5.1    Whenever any notice is required to be given to any
stockholder under the provisions of these By-laws, the Certificate of
Incorporation or the General Corporation Law of Delaware, a waiver thereof in
writing, signed by the person or persons entitled to such notice, whether before
or after the time stated therein, shall be deemed equivalent to the giving of
such notice.

                  2.5.2    The attendance of a stockholder at a meeting shall
constitute a waiver of notice of such meeting, except when a stockholder 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.

         2.6      FIXING OF RECORD DATE FOR DETERMINING STOCKHOLDERS.

                  2.6.1    MEETINGS.

         For the purpose of determining stockholders entitled to notice of and
to vote at any meeting of stockholders or any adjournment thereof, the Board may
fix a record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board, and

                                                                          Page 2



which record date shall not be more than sixty (or if less, the maximum number
permitted by applicable law) nor less than ten days before the date of such
meeting. If no record date is fixed by the Board, the record date for
determining 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. A determination of stockholders of record entitled to notice of and to
vote at the meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board may fix a new record date for the
adjourned meeting.

                  2.6.2    CONSENT TO CORPORATE ACTION WITHOUT A MEETING.

         For the purpose of determining stockholders entitled to consent to
corporate action in writing without a meeting, the Board may fix a record date,
which record date shall not precede the date upon which the resolution fixing
the record date is adopted by the Board, and which date shall not be more than
ten (or the maximum number permitted by applicable law) days after the date upon
which the resolution fixing the record date is adopted by the Board. If no
record date has been fixed by the Board, the record date for determining
stockholders entitled to consent to corporate action in writing without a
meeting, when no prior action by the Board is required by Chapter 1 of the
General Corporation Law of the State of Delaware, as now or hereafter amended,
shall be the first date on which a signed written consent setting forth the
action taken or proposed to be taken is delivered to the corporation by delivery
to its registered office in the State of 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. Delivery made to
a corporation's registered office shall be by hand or by certified or registered
mail, return receipt requested. If no record date has been fixed by the Board
and prior action by the Board is required by Chapter 1 of the General
Corporation Law of the State of Delaware, as now or hereafter amended, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting shall be at the close of business on the day on
which the Board adopts the resolution taking such prior action.

                                                                          Page 3



                  2.6.3    DIVIDENDS, DISTRIBUTIONS AND OTHER RIGHTS.

         For the purpose of determining stockholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or 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,
the Board may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted, and which record
date shall be not more than sixty (or the maximum number permitted by applicable
law) days prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board adopts the resolution relating thereto.

         2.7      VOTING LIST.

         At least ten days before each meeting of stockholders, a complete list
of the stockholders entitled to vote at such meeting, or any adjournment
thereof, shall be made, arranged in alphabetical order, with the address of and
number of shares held by each stockholder. This list shall be open to
examination by any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of ten 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. This list shall also be produced and kept at
such meeting for inspection by any stockholder who is present.

         2.8      QUORUM.

         A majority of the outstanding shares of the corporation entitled to
vote, present in person or represented by proxy at the meeting, shall constitute
a quorum at a meeting of the stockholders; provided, that where a separate vote
by a class or classes is required, a majority of the outstanding shares of such
class or classes, present in person or represented by proxy at the meeting,
shall constitute a quorum entitled to take action with respect to that vote on
that matter. If less than a majority of the outstanding shares entitled to vote
are represented at a meeting, a majority of the shares so represented may
adjourn the meeting from time to time without further notice. If a quorum is
present or represented at a reconvened meeting following such an adjournment,
any business may be transacted that might have been transacted at the

                                                                          Page 4



meeting as originally called. The stockholders present at a duly organized
meeting may continue to transact business until adjournment, notwithstanding the
withdrawal of enough stockholders to leave less than a quorum.

         2.9      MANNER OF ACTING.

         In all matters other than the election of Directors, if a quorum is
present, the affirmative vote of the majority of the outstanding shares present
in person or represented by proxy at the meeting and entitled to vote on the
subject matter shall be the act of the stockholders, unless the vote of a
greater number is required by these By-laws, the Certificate of Incorporation or
the General Corporation Law of Delaware. Where a separate vote by a class or
classes is required, if a quorum of such class or classes is present, the
affirmative vote of the majority of outstanding shares of such class or classes
present in person or represented by proxy at the meeting shall be the act of
such class or classes. Directors shall be elected by a plurality of the votes of
the shares present in person or represented by proxy at the meeting and entitled
to vote on the election of Directors.

         2.10     PROXIES.

                  2.10.1   APPOINTMENT.

         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 proxy. Such
authorization may be accomplished by (a) the stockholder or such stockholder's
authorized officer, director, employee or agent executing a writing or causing
his or signature to be affixed to such writing by any reasonable means,
including facsimile signature, or (b) by transmitting or authorizing the
transmission of a telegram, cablegram or other means of electronic transmission
to the intended holder of the proxy or to a proxy solicitation firm, proxy
support service or similar agent duly authorized by the intended proxy holder to
receive such transmission; provided, that any such telegram, cablegram or other
electronic transmission must either set forth or be accompanied by information
from which it can be determined that the telegram, cablegram or other electronic
transmission was authorized by the stockholder. Any copy, facsimile
telecommunication or other reliable reproduction of the writing or transmission
by which a stockholder has authorized another person to act as proxy for such
stockholder may be substituted or used in lieu of the original writing or

                                                                          Page 5



transmission for any and all purposes for which the original writing or
transmission could be used, provided that such copy, facsimile telecommunication
or other reproduction shall be a complete reproduction of the entire original
writing or transmission.

                  2.10.2   DELIVERY TO CORPORATION; DURATION.

         A proxy shall be filed with the Secretary of the Corporation before or
at the time of the meeting or the delivery to the Corporation of the consent to
corporate action in writing. A proxy shall become invalid three years after the
date of its execution unless otherwise provided in the proxy. A proxy with
respect to a specified meeting shall entitle the holder thereof to vote at any
reconvened meeting following adjournment of such meeting but shall not be valid

         Each stockholder entitled to vote at an election of Directors may vote,
in person or by proxy, the number of shares owned by such stockholder for as

shall (a) 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

the corporation having custody of the records of proceedings of meetings of
stockholders. Delivery made to the corporation's registered office shall be by
hand or by certified mail or registered mail, return receipt requested. Every

the stockholder shall be determined by or at the direction of the Secretary of
the Corporation. A written record of the information upon which the person
making such determination relied shall be made and kept in the records of the
proceedings of the stockholders. Prompt notice of the taking of the corporate
action without a meeting by less than unanimous written consent shall be given

number to be set by resolution of the Board, in accordance with the provisions
of the Certificate of Incorporation. The number of Directors may be changed from
time to time by amendment to these By-laws, but no decrease in the number of

Director. Unless a Director dies, resigns, or is removed, he or she shall hold
office until the next annual meeting of stockholders or until his or her
successor is elected, whichever is later. Directors need not

                                                                          Page 7

election of directors may be made (a) by or at the direction of the Board, or
(b) by any stockholder of record entitled to vote for the election of directors
at the annual stockholder meeting; provided, however, that a stockholder may
nominate a person for election as a director only if written nomination is
received by the Secretary not less than seven (7) nor more than thirty (30) days
prior to the date of such annual meeting. Any such stockholder's nomination
shall set forth (a) the name and address of the stockholder who is making the
nomination, (b) as to each person the stockholder nominates for election, the

procedure and, if it is so determined, the defective nomination shall be
disregarded. The foregoing procedure is subject to the rights of the holders of
any class or series of stock having a preference over the Common Stock.

                  3.8.2    BY ATTENDANCE.

taken shall be presumed to have assented to the action taken unless his or her

of the Board, shall constitute a quorum for the transaction of business at any
meeting of such committee but, if less than a majority are present at a meeting,
a majority of such Directors present may adjourn the meeting from time to time

present at a meeting at which a quorum is present shall be the act of such
committee.

                  registered under the Securities Act of 1933 or any applicable
                  state law, and no interest therein may be sold, distributed,
                  assigned, offered, pledged or otherwise transferred unless (a)
                  there is an effective registration statement under such Act
                  and applicable state securities laws covering any such
                  transaction involving said securities or (b) this corporation
                  receives an opinion of legal counsel for the holder of these
                  securities (concurred in by legal counsel for this
                  corporation) stating that such transaction is exempt from
                  registration or this corporation otherwise satisfies itself
                  that such transaction is exempt from registration. Neither the
                  offering of the securities nor any

                                                                         Page 18



                  offering materials have been reviewed by any administrator
                  under the Securities Act of 1933 or any applicable state law."

         6.5      TRANSFER OF SHARES.

         The transfer of shares of the corporation shall be made only on the
stock transfer books of the corporation pursuant to authorization or document of
transfer made by the holder of record thereof or by his or her legal
representative, who shall furnish proper evidence of authority to transfer, or
by his or her attorney-in-fact authorized by power of attorney duly executed and
filed with the Secretary of the corporation. All certificates surrendered to the
corporation for transfer shall be cancelled and no new certificate shall be
issued until the former certificates for a like number of shares shall have been
surrendered and cancelled.

         6.6      LOST OR DESTROYED CERTIFICATES.

         In the case of a lost, destroyed or mutilated certificate, a new
certificate may be issued therefor upon such terms and indemnity to the
corporation as the Board may prescribe.

                          SECTION 7. BOOKS AND RECORDS

         The corporation shall keep correct and complete books and records of
account, stock transfer books, minutes of the proceedings of its stockholders
and Board and such other records as may be necessary or advisable.

                           SECTION 8. ACCOUNTING YEAR

         The accounting year of the corporation shall be the twelve months ended
October 31, provided that if a different accounting year is at any time selected
for purposes of federal income taxes, the accounting year shall be the year so
selected.

                                 SECTION 9. SEAL

         The seal of the corporation shall consist of the name of the
corporation, the state of its incorporation and the year of its incorporation.

                                                                         Page 19



                           SECTION 10. INDEMNIFICATION

         10.1     RIGHT TO INDEMNIFICATION.

         Each person who was or is made a party or is threatened to be made a
party to or is otherwise involved (including, without limitation, as a witness)
in any actual or threatened action, suit or proceeding, whether civil, criminal,
administrative or investigative (hereinafter a "proceeding"), by reason of the
fact that he or she is or was a Director or officer of the corporation or that,
being or having been such a Director or officer or an employee of the
corporation, he or she is or was serving at the request of the corporation as a
Director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to an
employee benefit plan (hereinafter an "indemnitee"), whether the basis of such
proceeding is alleged action in an official capacity as such a Director,
officer, employee or agent or in any other capacity while serving as such a
Director, officer, employee or agent, shall be indemnified and held harmless by
the corporation to the full extent permitted by the General Corporation Law of
Delaware, as the same exists or may hereafter be amended (but, in the case of
any such amendment, only to the extent that such amendment permits the
corporation to provide broader indemnification rights than permitted prior
thereto), or by other applicable law as then in effect, against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) actually and reasonably
incurred or suffered by such indemnitee in connection therewith and such
indemnification shall continue as to an indemnitee who has ceased to be a
Director, officer, employee or agent and shall inure to the benefit of the
indemnitee's heirs, executors and administrators; provided, however, that except
as provided in subsection 10.2 of this Section with respect to proceedings
seeking to enforce rights to indemnification, the corporation shall indemnify
any such indemnitee in connection with a proceeding (or part thereof) initiated
by such indemnitee only if such proceeding (or part thereof) was authorized or
ratified by the Board. The right to indemnification conferred in this subsection
10.1 shall be a contract right and shall include the right to be paid by the
corporation the expenses incurred in defending any such proceeding in advance of
its final disposition (hereinafter an "advancement of expenses"); provided,
however, that if the General Corporation Law of Delaware requires, an
advancement of expenses incurred by an indemnitee in his or her capacity as a
Director or officer (and not in any other capacity in which service was or is

                                                                         Page 20



rendered by such indemnitee, including, without limitation, service to an
employee benefit plan) shall be made only upon delivery to the corporation of an
undertaking (hereinafter an "undertaking"), by or on behalf of such indemnitee,
to repay all amounts so advanced if it shall ultimately be determined by final
judicial decision from which there is no further right to appeal that such
indemnitee is not entitled to be indemnified for such expenses under this
subsection 10.1 or otherwise.

         10.2     RIGHT OF INDEMNITEE TO BRING SUIT.

         If a claim under subsection 10.1 of this Section is not paid in full by
the corporation within sixty days after a written claim has been received by the
corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty days, the indemnitee may at any
time thereafter bring suit against the corporation to recover the unpaid amount
of the claim. If successful in whole or in part in any such suit, or in a suit
brought by the corporation to recover an advancement of expenses pursuant to the
terms of an undertaking, the indemnitee shall be entitled to be paid also the
expense of prosecuting or defending such suit. The indemnitee shall be presumed
to be entitled to indemnification under this Section upon submission of a
written claim (and, in an action brought to enforce a claim for an advancement
of expenses, where the required undertaking, if any is required, has been
tendered to the corporation), and thereafter the corporation shall have the
burden of proof to overcome the presumption that the indemnitee is not so
entitled. Neither the failure of the corporation (including its Board,
independent legal counsel or its stockholders) to have made a determination
prior to the commencement of such suit that indemnification of the indemnitee is
proper in the circumstances nor an actual determination by the corporation
(including its Board, independent legal counsel or its stockholders) that the
indemnitee is not entitled to indemnification shall be a defense to the suit or
create a presumption that the indemnitee is not so entitled.

         10.3     NONEXCLUSIVITY OF RIGHTS.

         The rights to indemnification and to the advancement of expenses
conferred in this Section shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, agreement, vote of
stockholders or disinterested Directors, provisions of the Certificate of
Incorporation or By-laws of the corporation or otherwise.

                                                                         Page 21



         10.4     INSURANCE, CONTRACTS AND FUNDING.

         The corporation may maintain insurance, at its expense, to protect
itself and any Director, officer, employee or agent of the corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the corporation would
have the power to indemnify such person against such expense, liability or loss
under the General Corporation Law of Delaware. The corporation, without further
stockholder approval, may enter into contracts with any Director, officer,
employee or agent in furtherance of the provisions of this Section and may
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 amounts as
may be necessary to effect indemnification as provided in this Section.

         10.5     INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE CORPORATION.

         The corporation may, by action of the Board, grant rights to
indemnification and advancement of expenses to employees or agents or groups of
employees or agents of the corporation with the same scope and effect as the
provisions of this Section with respect to the indemnification and advancement
of expenses of Directors and officers of the corporation; provided, however,
that an undertaking shall be made by an employee or agent only if required by
the Board.

         10.6     PERSONS SERVING OTHER ENTITIES.

         Any person who is or was a Director, officer or employee of the
corporation who is or was serving (a) as a Director or officer of another
corporation of which a majority of the shares entitled to vote in the election
of its Directors is held by the corporation or (b) in an executive or management
capacity in a partnership, joint venture, trust or other enterprise of which the
corporation or a wholly owned subsidiary of the corporation is a general partner
or has a majority ownership shall be deemed to be so serving at the request of
the corporation and entitled to indemnification and advancement of expenses
under subsection 10.1 of this Section.

          SECTION 11. SHARES REGISTERED IN THE NAME OF THE CORPORATION

         The Board shall designate officers of the Corporation who shall have
authority from time to time to appoint an agent or

                                                                         Page 22



agents of the corporation to exercise in the name and on behalf of the
corporation the powers and rights which the corporation may have as the holder
of stock or other securities in any other corporation, and to vote or consent in
respect of such stock or securities. Such designated officers may instruct the
person or persons so appointed as to the manner of exercising such powers and
rights, and such designated officers may execute or cause to be executed in the
name and on behalf of the corporation and under its corporate seal, or
otherwise, such written proxies, powers of attorney or other instruments as they
may deem necessary or proper in order that the corporation may exercise its
powers and rights.

                             SECTION 12. AMENDMENTS

         These By-laws may be amended or repealed and new By-laws may be adopted
by the Board. The stockholders may also amend and repeal these By-laws or adopt
new By-laws. All By-laws made by the Board may be amended or repealed by the
stockholders.

         The foregoing By-laws were adopted by the Board of Directors on July
14, 1992.
