ITEM 4.          CHANGE IN REGISTRANT'S CERTIFYING ACCOUNTANT.


        On September 2, 1996, Registrant, acting upon the authorization of its
Board of Directors, selected Arthur Andersen L.L.P. as its principal
independent accountant to replace Jones, Jensen & Co. Except as described
below, the reports of Registrant's prior principal accountant for the two most
recent fiscal years did not contain an adverse opinion or disclaimer of
opinion, or modification as to uncertainty, audit scope, or accounting
principles.  The reports related to periods before Registrant acquired its
current business operations and to periods in which  Registrant was a
development stage company.  Accordingly, the reports noted that Registrant was
a development stage company which had no significant operating results to the
date of such reports and stated that unless Registrant was able to obtain
significant outside financing, there existed substantial doubt of its ability
to continue as a going concern.

        There were no disagreements with the Registrant's former
principal accountant on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure.


ITEM 5.          OTHER EVENTS.


        Effective September 3, 1996, the Registrant amended its
Certificate of Incorporation and Bylaws. Among other things, the Amended and
Restated Certificate of Incorporation changed the name of the Registrant to
Unidyne Corporation.  Copies of the Amended and Restated Certificate of
Incorporation and Amended and Restated Bylaws are attached hereto as Exhibits
3.1 and 3.2, respectively.

                           BLUE JAY ENTERPRISES, INC.


         BLUE JAY ENTERPRISES, INC., a corporation organized and existing under
the law of the State of Delaware (the "CORPORATION"), hereby certifies as
follows:

         1.      The Corporation was originally incorporated under the name
BLUE JAY PETROLEUM CORP., and the name was subsequently changed to BLUE JAY

value $10.00, create a classified board of directors, limit stockholder actions
to those actions taken at meetings of the stockholders, limit the ability to
amend certain provisions of the Certificate of Incorporation, as amended, or
the Corporation's bylaws, limit the personal liability of directors to the
Corporation or its stockholders, and authorize indemnification of the
Corporation's directors, and also integrates and restates the Certificate of
Incorporation, as amended and heretofore in effect and as further amended
hereby.

         4.      This Amended and Restated Certificate of Incorporation has
been proposed by the Board of Directors of the Corporation and adopted by the
stockholders of the Corporation in the manner and by the vote prescribed by
Sections 242 and 245 of the General Corporation Law of the State of Delaware
(the "CORPORATION LAW"), and is as follows:

         THIRD:  The purpose of the Corporation is to engage in any lawful act
or activity for which corporations may be organized under the Corporation Law.

         FOURTH:  The total number of shares of stock which the Corporation has

<PAGE>   4
shares, of which Fifty Million (50,000,000) shares shall be Common Stock of the
par value of $0.001 per share (the "COMMON STOCK") and Twenty Million
(20,000,000) shares shall be Preferred Stock of the par value of $10.00 per
share (the "PREFERRED STOCK").  The Corporation shall be entitled to treat the
person in whose name any share of its stock is registered as the owner thereof
for all purposes and shall not be bound to recognize any equitable or other
claim to, or interest in, such share on the part of any other person, whether
or not the Corporation shall have notice thereof, except as expressly provided
by applicable law.  The shares of the Preferred Stock and Common Stock,
respectively, shall have the following express terms:

         SECTION 1.  PREFERRED STOCK.

         1.1 AUTHORITY OF THE BOARD OF DIRECTORS TO CREATE SERIES. The Board of
Directors of the Corporation is hereby expressly granted authority, to the full
extent now or hereafter permitted herein and by the Corporation Law, at any
time or from time to time, by resolution or resolutions, to create one or more
series of Preferred Stock, to fix the authorized number of shares of any such
series (which number of shares may vary as between series and be changed from
time to time by like action), and to fix the terms of such series, including
but not limited to, the following:

                 (i)      the designation of such series, which may be by
         distinguishing number, letter or title;

                 (ii)     the rate or rates at which shares of such series
         shall be entitled to receive dividends; the periods in respect of
         which dividends are payable; the conditions upon, and times of payment
         of, such dividends; the relationship and preference, if any, of such
         dividends to dividends payable on any other class or classes or any
         other series of stock; whether such dividends shall be cumulative and,
         if cumulative, the date or dates from which such dividends shall
         accumulate; and the other terms and conditions applicable to dividends
         upon shares of such series;

                 (iii)    the rights of the holders of the shares of such
         series in case the Corporation be liquidated, dissolved or wound up
         (which may vary depending upon the time, manner or voluntary or
         involuntary nature or other circumstances of such liquidation,
         dissolution or winding up) and the relationship and preference, if
         any, of such rights to rights of holders of shares of stock of any
         other class or classes or any other series of stock;

                 (iv)     the right, if any, of the Corporation to redeem
         shares of such series at its option, including any limitation of such
         right, and the amount or amounts to be payable in respect of the
         shares of such series in case





                                     - 2 -
<PAGE>   5
         of such redemption (which may vary depending on the time, manner or
         other circumstances of such redemption), and the manner, effect and
         other terms and conditions of any such redemption;

                 (v)      the obligation, if any, of the Corporation to
         purchase, redeem or retire shares of such series and/or to maintain a
         fund for such purpose, and the amount or amounts to be payable from
         time to time or such purpose or into such fund, or the number of
         shares to be purchased, redeemed or retired, the per share purchase
         price or prices, and the other terms and conditions of any such
         obligation or obligations;

                 (vi)     the voting rights, if any, which, if granted, may be
         full, special, or limited, to be given the shares of such series,
         including, without limiting the generality of the foregoing, the
         right, if any, as a series or in conjunction with other series or
         classes, to elect one or more members of the Board of Directors either
         generally or at certain times or under certain circumstances, and
         restrictions, if any, on particular corporate acts without a specified
         vote or consent of holders of such shares (such as, among others,
         restrictions on modifying the terms of such series or of the Preferred
         Stock, restricting the permissible terms of other series or the
         permissible variations between series of the Preferred Stock,
         authorizing or issuing additional shares of the Preferred Stock,
         creating debt, or creating any class of stock ranking prior to or on a
         parity with the Preferred Stock or any series thereof as to dividends,
         or assets remaining for distribution to the stockholders in the event
         of the liquidation, dissolution, or winding up of the Corporation);

                 (vii) the right, if any, to exchange or convert the shares
         into shares of any other series of the Preferred Stock or into shares
         of any other class of stock of the Corporation or the securities of
         any other corporation, and the rate or basis, time, manner, terms and
         conditions of exchange or conversion or the method by which the same
         shall be determined; and

                 (viii)  the other special rights, if any, and the
         qualifications, limitations or restrictions thereof, of the shares of
         such series.

         The Board of Directors shall fix the terms of each series of the
Preferred Stock by resolution or resolutions adopted at any time prior to the
issuance of the shares thereof, and the terms of each such series may, subject
only to restrictions, if any, imposed by this Amended and Restated Certificate
of Incorporation or by applicable law, vary from the terms of other series to
the extent





                                     - 3 -
<PAGE>   6
determined by the Board of Directors from time to time and provided in the
resolution or resolutions fixing the terms of the respective series of the
Preferred Stock.

         1.2     STATUS OF CERTAIN SHARES.  Shares of any series of the
Preferred Stock, whether provided for herein or by resolution or resolutions of
the Board of Directors, which have been redeemed (whether through the operation
of a sinking fund or otherwise) or which, if convertible or exchangeable, have
been converted into or exchanged for shares of stock of any other class or
classes, or which have been purchased or otherwise acquired by the Corporation,
shall have the status of authorized and unissued shares of the Preferred Stock
of the same series and may be reissued as a part of the series of which they
were originally a part or may be reclassified and reissued as part of a new
series of the Preferred Stock to be created by resolution or resolutions of the
Board of Directors or as part of any other series of the Preferred Stock, all
subject to the conditions or restrictions on issuance set forth herein or in
the resolution or resolutions adopted by the Board of Directors providing for
the issue of any series of the Preferred Stock.

         1.3     CHANGES IN NUMBER OF AUTHORIZED SHARES.  The number of
authorized shares of Preferred Stock may be increased or decreased (but not
below the number of shares thereof then outstanding) by the affirmative vote of
the holders of a majority of the outstanding Common Stock, without a vote of
the holders of the Preferred Stock, or of any series thereof, unless a vote of
any such holders is required pursuant to the express terms of the Preferred
Stock or any series thereof as fixed or determined pursuant to this Section 1
of this Article FOURTH.

         SECTION 2.  COMMON STOCK.

         2.1     ISSUANCE, CONSIDERATION AND TERMS.  Any unissued or treasury
shares of the Common Stock may be issued from time to time for such
consideration as may be fixed from time to time by the Board of Directors.  The
Common Stock shall be subject to the express terms of the Preferred Stock and
any series thereof. Each share of Common Stock shall be of equal rank and shall
be identical to every other share of Common Stock.  Holders of Common Stock
shall have such rights as are provided herein and by law.

         2.2     VOTING RIGHTS.  Except as expressly required by law or as
provided in or fixed and determined pursuant to Section 1 of this Article
FOURTH, the entire voting power and all voting rights shall be vested
exclusively in the Common Stock.  Each holder of shares of Common Stock shall
be entitled to one (1) vote for each share standing in such holder's name on
the books of the Corporation.

         2.3     DIVIDENDS.  Subject to Section 1 of this Article FOURTH, the
holders of Common Stock shall be entitled to receive, and shall share equally
share for share, when and as declared by the Board of





                                     - 4 -
<PAGE>   7
Directors, out of the assets of the Corporation which are by law available
therefor, dividends or distributions payable in cash, in property or in
securities of the Corporation.

         FIFTH:  Any action required or permitted to be taken by the
stockholders of the Corporation must be effected at a duly called annual or
special meeting of such holders and may not be effected by any consent in
writing by such holders.  Except as otherwise required by law and subject to
the rights of the holders of any class or series of stock having a preference
over the Common Stock as to dividends or upon liquidation, special meetings of
stockholders of the Corporation for any purpose or purposes may be called only
by the Board of Directors pursuant to a resolution stating the purpose or
purposes thereof approved by a majority of the total number of directors which
the Board of Directors of the Corporation would have if there were no vacancies
(the "WHOLE BOARD") or by the Chairman of the Board of Directors of the
Corporation and any power of stockholders to call a special meeting is
specifically denied.  No business other than that stated in the notice shall be
transacted at any special meeting.  Notwithstanding anything contained in this
Amended and Restated Certificate of Incorporation to the contrary, the
affirmative vote of the holders of at least 80% of the voting power of all
shares of the Corporation entitled to vote generally in the election of
directors (the "VOTING STOCK") then outstanding, voting together as a single
class, shall be required to alter, amend, or adopt any provision inconsistent
with or repeal this Article FIFTH.

         SIXTH:  The following provisions of this Article SIXTH shall apply
with respect to the Board of Directors of the Corporation:

         SECTION 1.  NUMBER, ELECTION AND TERMS.

         Except as otherwise fixed by or pursuant to the provisions of Article
FOURTH hereof relating to the rights of the holders of any shares of the
Preferred Stock or any series thereof having a preference over the Common Stock
as to dividends or upon liquidation to elect additional directors under
specified circumstances, the number of the directors of the Corporation shall
be fixed from time to time exclusively pursuant to a resolution adopted by a
majority of the Whole Board (but shall not be less than two).  So long as there
shall be more than two directors, the directors, other than those who may be
elected by the holders of any shares of Preferred Stock or series thereof
having a preference over the Common Stock as to dividends or upon liquidation,
shall be classified, with respect to the time for which they severally hold
office, into, three classes, as nearly equal in number as possible, one class
to be originally elected for a term expiring at the annual meeting of
stockholders to be held in 1997, another class to be originally elected for a
term expiring at the annual meeting of stockholders to be held in 1998, and
another class to be originally elected for a term expiring at the annual
meeting of stockholders to be held in 1999, with each class to hold office
until its





                                     - 5 -
<PAGE>   8
successor is duly elected and qualified.  At each succeeding annual meeting of
stockholders, directors elected to succeed those directors whose terms then
expire shall be elected for a term of office to expire at the third succeeding
annual meeting of stockholders after their election, with each director to hold
office until such person's successor shall have been duly elected and
qualified. Election of directors need not be by written ballot unless and to
the extent that the Bylaws of the Corporation so provide.

         SECTION 2.  STOCKHOLDER NOMINATIONS AND PROPOSALS.

         Advance notice of stockholder nominations for the election of
directors and of the proposal of business by stockholders shall be given in the
manner provided in the Bylaws of the Corporation, as amended and in effect from
time to time.

         SECTION 3.  NEWLY CREATED DIRECTORSHIPS AND VACANCIES.

         Except as otherwise provided for or fixed by or pursuant to the
provisions of Article FOURTH hereof relating to the rights of the holders of
any class or series of the Preferred Stock having a preference over the Common
Stock as to dividends or upon liquidation to elect directors under specified
circumstances, newly created directorships resulting from any increase in the
number of directors and any vacancies on the Board of Directors resulting from
death, resignation, disqualification, removal or other cause shall be filled by
the affirmative vote of a majority of the remaining directors then in office,
even though less than a quorum of the Board of Directors, and not by the
stockholders.  Any director elected in accordance with the preceding sentence
shall hold office for the remainder of the full term of the class of directors
in which the new directorship was created or the vacancy occurred and until
such director's successor shall have been duly elected and qualified.  No
decrease in the number of directors constituting the Board of Directors shall
shorten the term of any incumbent director.

         SECTION 4.  REMOVAL.

         Subject to the rights of any class or series of the Preferred Stock
having a preference over the Common Stock as to dividends or upon liquidation
to elect Directors under specified circumstances, any director may be removed
from office only for cause by the affirmative vote of the holders of at least a
majority of the voting power of all Voting Stock then outstanding, voting
together as a single class.

         SECTION 5.  AMENDMENT, REPEAL, ETC.

         Notwithstanding anything contained in this Amended and Restated
Certificate of Incorporation to the contrary, the affirmative vote of the
holders of at least 80% of the voting power





                                     - 6 -
<PAGE>   9
of all Voting Stock then outstanding, voting together as a single class, shall
be required to alter, amend, adopt any provision inconsistent with or repeal
this Article SIXTH.

         SEVENTH:         The Bylaws of the Corporation may be altered or
repealed and new Bylaws may be adopted either:  (1) at any annual or special
meeting of stockholders, by the affirmative vote of the holders of a majority
of the voting power of the stock issued and outstanding and entitled to vote
thereat, provided that any proposed alteration or repeal of, or the adoption of
any Bylaw inconsistent with this sentence, by the stockholders shall require
the affirmative vote of the holders of at least 80% of the voting power of all
Voting Stock then outstanding, voting together as a single class; and provided,
further, that in the case of any such stockholder action at a special meeting
of stockholders, notice of the proposed alteration, repeal or adoption of the
new Bylaw or Bylaws must be contained in the notice of such special meeting; or
(2) by the affirmative vote of a majority of the Whole Board.

Notwithstanding anything contained in this Certificate of Incorporation to the
contrary, the affirmative vote of the holders of at least 80% of the voting
power of all Voting Stock then outstanding, voting together as a single class,
shall be required to alter, amend, adopt any provision inconsistent with or
repeal this Article SEVENTH.

         EIGHTH: The Corporation reserves the right at any time and from time
to time to amend, alter, change or repeal any provision contained in this
Amended and Restated Certificate of Incorporation, and any other provisions
authorized by the laws of the State of Delaware at the time in force may be
added or inserted, in the manner now or hereafter prescribed by law; and,
except as set forth in Article ELEVENTH, all rights, preferences and privileges
of whatsoever nature conferred upon stockholders, directors or any other
persons whomsoever by and pursuant to this Amended and Restated Certificate of
Incorporation in its present form or as hereafter amended are granted subject
to the right reserved in this Article EIGHTH.  Notwithstanding anything
contained in this Amended and Restated Certificate of Incorporation to the
contrary, the affirmative vote of the holders of at least 80% of the Voting
Stock then outstanding, voting together as a single class, shall be required to
alter, amend, adopt any provision inconsistent with or repeal Articles FIFTH,
SIXTH, SEVENTH or EIGHTH hereof.

         NINTH:  A director of the Corporation shall not be personally liable
to the Corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for such liability as is expressly not
subject to limitation under the Corporation Law as the same exists or hereafter
may be amended.  Neither the amendment nor repeal of this Article NINTH shall
eliminate or reduce the effect of Section 1 of this Article NINTH in respect of
any matter occurring, or any cause of action, suit or





                                     - 7 -
<PAGE>   10
claim that, but for this Article NINTH would accrue or arise, prior to such
amendment or repeal.

         TENTH: Whenever a compromise or arrangement is proposed between the
Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under
the provisions of Section 291 of the Corporation Law or on the application of
trustees in dissolution or of any receiver or receivers appointed for the
Corporation under the provisions of Section 279 of the Corporation Law, order a
meeting of the creditors or class of creditors, and/or of the stockholders or
class of stockholders of the Corporation, as the case may be, to be summoned in
such manner as the said court directs.  If a majority in number representing
three-fourths in value of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the Corporation, as the case may be,
agree to any compromise or arrangement and to any reorganization of the
Corporation as a consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of the Corporation, as the case may be, and also on the
Corporation.

         ELEVENTH: The Corporation shall indemnify the persons described in the
following provisions of this Article ELEVENTH to the extent set forth herein:

         SECTION 1.  INDEMNIFICATION.

         Each person who was or is made a party to, or is threatened to be made
a party to, or who was or is made a nonparty witness or otherwise involved as a
nonparty in, any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (hereafter a
"PROCEEDING") by reason of the fact that he or she, or a person of whom he or
she is the legal representative, is or was or has agreed to become a director
or officer of the Corporation, or is or was serving or has agreed to serve at
the request of the Corporation as a director, officer, trustee, employee, or
agent of another corporation, partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, whether
the basis of such action, suit or proceeding is alleged in an official capacity
as a director, officer, employee, agent or trustee or in any other capacity
while serving as a director, officer, employee, agent or trustee, shall be
indemnified and held harmless by the Corporation to the fullest extent
authorized by the Corporation Law (as the same now exists or hereafter may be
amended, but in the event of any such amendment only to the extent that such
amendment





                                     - 8 -
<PAGE>   11
authorizes broader indemnification rights than the Corporation Law permitted
prior to such amendment) from and against any and all liability, loss and
expense (including attorneys' fees, judgments, fines, ERISA excise taxes and
penalties and amounts paid or to be paid in settlement) actually and reasonably
incurred or suffered by such person in connection with such proceeding and any
appeal therefrom and such indemnification shall continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such person; provided
that, except as provided in Section 2 of this Article ELEVENTH, the Corporation
shall indemnify any such person seeking indemnification in connection with a
proceeding (or part thereof) initiated by such person only if such proceeding
(or part thereof) was authorized by the Board of Directors of the Corporation.
The right to indemnification conferred in this Section 1 of this Article
ELEVENTH shall be a contract right and shall include the right to have the
Corporation pay the expenses incurred in defending any such proceeding in
advance of its final disposition; any advance payments to be paid by the
Corporation shall be paid within 30 calendar days after the receipt by the
Corporation of a statement or statements from the claimant requesting such
advance or advances from time to time; provided, however, that, if and to the
extent the Corporation Law requires, the payment of such expenses incurred by a
director or officer in such person's capacity as a director or officer (and not
in any other capacity) in advance of the final disposition of a proceeding,
shall be made only upon delivery to the Corporation of an undertaking, by or on
behalf of such director or officer, to repay all amounts so advanced if it
shall ultimately be determined that such director or officer is not entitled to
be indemnified under this Article ELEVENTH or otherwise.  The Corporation may,
to the extent authorized from time to time by the Board of Directors, grant
rights to indemnification, and rights to have the Corporation pay the expenses
incurred in defending any proceeding in advance of its final disposition, to
any employee or agent of the Corporation to the fullest extent of the
provisions of this Article ELEVENTH with respect to the indemnification and
advancement of expenses of directors and officers of the Corporation.

         SECTION 2.  RIGHT OF CLAIMANT TO BRING SUIT.

         If a claim under Section 1 of this Article ELEVENTH is not paid in
full by the Corporation within 30 calendar days after a written claim has been
received by the Corporation, the claimant may at any time thereafter bring suit
against the Corporation to recover the unpaid amount of the claim and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim.  It shall be a defense to any such
action (other than an action brought to enforce a claim for expenses incurred
in defending any proceeding in advance of its final disposition where the
required undertaking, if any is required, has been tendered to the Corporation)
that the claimant has not met the standard of conduct which makes it
permissible





                                     - 9 -
<PAGE>   12
under the Corporation Law for the Corporation to indemnify the claimant for the
amount claimed, but the burden of proving such defense shall be on the
Corporation.  Neither the failure of the Corporation (including its Board of
Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because the claimant has met the
applicable standard of conduct set forth in the Corporation Law, nor an actual
determination by the Corporation (including its Board of Directors, independent
legal counsel, or its stockholders) that the claimant has not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that the claimant has not met the applicable standard of conduct.

         SECTION 3.  NON-EXCLUSIVITY OF RIGHTS.

         The right to indemnification and the payment of expenses incurred in
defending a proceeding in advance of its final disposition conferred in this
Article ELEVENTH shall not be exclusive of any other right which any person may
have or hereafter acquire under any statute, provision of this Amended and
Restated Certificate of Incorporation or any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.  No repeal or
modification of this Article ELEVENTH shall in any way diminish or adversely
affect the rights herein conferred on any director or officer of the
Corporation, or any other person specified herein, in respect of any occurrence
or matter arising prior to any such repeal or modification.

         SECTION 4.  INSURANCE.

         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 such 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 Corporation Law.

         SECTION 5.  SEVERABILITY.

         If any provision or provisions of this Article ELEVENTH shall be held
to be invalid, illegal or unenforceable for any reason whatsoever:  (1) the
validity, legality and enforceability of the remaining provisions of this
Article ELEVENTH (including, without limitation, each portion of any paragraph
of this Article ELEVENTH containing any such provision held to be invalid,
illegal or unenforceable, that is not itself held to be invalid, illegal or
unenforceable) shall not in any way be affected or impaired thereby; and (2) to
the fullest extent possible, the provisions of this Article ELEVENTH
(including, without limitation, each such portion of any paragraph of this
Article ELEVENTH containing any such provision held to be invalid, illegal or
unenforceable) shall





                                     - 10 -
<PAGE>   13
be construed so as to give effect to the intent manifested by the provision
held invalid, illegal or unenforceable.

         IN WITNESS WHEREOF, the Corporation has caused this Amended and
Restated Certificate of Incorporation to be signed by its President and
attested by its Secretary as of this 2nd day of September, 1996.

Class B directors at the second succeeding annual meeting of shareholders, and

<PAGE>   19
as constituted from time to time shall constitute a quorum for the transaction
of business, but, if at any meeting of the Board of Directors (whether or not

committees, each committee to consist of one or more of the directors of the
corporation.  The Board may designate one or more directors as alternate

a committee, the member or members thereof present at any meeting and not
disqualified from 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 place of any such absent or disqualified member.  Any such
committee, to the extent provided in





                                     - 5 -
<PAGE>   20
the resolution of the Board of Directors, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the
business, property, and affairs of the corporation, and may authorize the seal
of the corporation to be affixed to all papers which may require it; but no
such committee shall have power or authority in reference to amending the
Certificate of Incorporation of the corporation (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 pursuant to
authority expressly granted to the Board of Directors by the Certificate of
Incorporation, fix 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, shares
of any other class or classes or any other series of the same or any other
class or classes of stock of the corporation), adopting an agreement of merger

                                     - 6 -
<PAGE>   21
General Corporation Law of the State of Delaware.  Each committee which may be
established by the Board of Directors pursuant to these Bylaws may fix its own
rules and procedures.  Notice of meetings of committees, other than of regular
meetings provided for by the rules, shall be given to committee members.  All
action taken by committees shall be recorded in minutes of the meetings.

                          SECTION 2.6  ACTION WITHOUT MEETING.  Nothing
contained in these Bylaws shall be deemed to restrict the power of members of
the Board of Directors or any committee designated by the Board to take any
action required or permitted to be taken by them without a meeting.

                          SECTION 2.7  TELEPHONE MEETINGS.  Nothing contained
in these Bylaws shall be deemed to restrict the power of members of the Board
of Directors, or any committee designated by the Board, to participate in a
meeting of the Board, or committee, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other.

may deem necessary or desirable.  Each officer shall hold office for such term
as may be prescribed by the Board of Directors from time to time.  Any person
may hold at one time two or more offices.

                          SECTION 3.2  POWERS AND DUTIES.  The Chairman shall
preside at all meetings of the stockholders and of the Board of Directors.  In
the absence of the Chairman, the President, or a Vice President appointed by

of the corporation shall each have such powers and authority and shall perform
such duties in the management of the business, property, and affairs of the
corporation as generally pertain to their respective offices, as well as such
powers and authorities and such duties as from time to time may be prescribed
by the Board of Directors.

meeting thereof, or by written consent, at any time, may, to the extent
permitted by law, remove with or without cause from office or terminate the
employment of any officer or member of any committee and may, with or without
cause, disband any committee.

                          (b)  Any director or the entire Board of Directors
may be removed, with or without cause, by the holders of a majority of the
shares entitled at the time to vote at an election of directors.

                          SECTION 4.3  VACANCIES.  Any vacancy in the office of
any director or officer through death, resignation, removal, disqualification,
or other cause, and any additional directorship resulting from increase in the
number of directors, may be filled at any time by a majority of the directors
then in office (even though less than a quorum remains) or, in the case of any
vacancy in the office of any director, by the stockholders, and, subject to the
provisions of this Article IV, the person so chosen shall hold office until his
successor shall have been elected and qualified; or, if the person so chosen is
a director elected to fill a vacancy, he shall (subject to the provisions of

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, unless otherwise provided by law,

any certificate or certificates theretofore issued by the corporation, alleged

authorized to do so by a resolution of 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 give the corporation a bond in such sum as the Board
of Directors (or any transfer agent so authorized) shall direct to indemnify
the corporation against any claim that may be made against the corporation with
respect to the certificate alleged to have been lost, stolen, or destroyed or
the issuance of such new certificates, and such requirement may be general or
confined to specific instances.
