mean a purpose 



reasonably related to such person's interest as a stockholder. In every instance

such other writing which authorizes the attorney or other agent to so act on
behalf of the stockholder. The demand under oath shall be directed to the

      If no record date is fixed:

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

            (b) The record date for determining stockholders entitled to express
      consent to corporate action in writing without a meeting, when no prior
      action by the Board of Directors is necessary, shall be the day on which
      the first written consent is expressed.

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




            (d) A determination of stockholders of record entitled to notice of

      the meeting; provided, however, that the Board of Directors may fix a new
      record date for the adjourned meeting.

      Section 5. DIVIDENDS: The Board of Directors may declare and pay dividends

maintaining any property of the corporation, or for such other purpose as the

stockholders, the general nature of the business to be transacted.

      Section 4. WAIVER OF NOTICE: Whenever any written notice is required by
statute, or by the Certificate or the By-Laws of this corporation 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. Except in the case of a special meeting of
stockholders, neither the business to be transacted at nor the purpose of the
meeting need be specified in the waiver of notice of such meeting. Attendance of
a person either in person or by proxy, at any meeting shall constitute a waiver
of notice of such meeting, except where a person attends a meeting for the
express purpose of objecting to the transaction of any business because the
meeting was not lawfully called or convened.

      Section 5. DISALLOWED COMPENSATION: Any payments made to an officer or
employee of the corporation such as a salary, commission, bonus, interest, rent,
travel or entertainment expense incurred by him, which shall be disallowed in
whole or in part as a deductible expense by the Internal Revenue Service, shall
be reimbursed by such officer or employee to the corporation to the full extent
of such 



disallowance. It shall be the duty of the directors, as a Board, to enforce
payment of each such amount disallowed. In lieu of payment by the officer or
employee, subject to the determination of the directors, proportionate amounts
may be withheld from his future compensation payments until the amount owed to
the corporation has been recovered.

receipt by the corporation, unless some time be fixed in the resignation and

make it effective.

                          ARTICLE X - ANNUAL STATEMENT

      Section 1. The President and the Board of Directors shall present at each
annual meeting a full and complete statement of the business and affairs of the
corporation for the preceding year. Such statement shall be prepared and
presented in whatever manner the Board of Directors shall deem advisable and
need not be verified by a Certified Public Accountant.

                   ARTICLE XI - INDEMNIFICATION AND INSURANCE:

      Section 1. (a) RIGHT TO INDEMNIFICATION. Each person who was or is made a
party or is threatened to be made a party or is involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative
(hereinafter 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 a director or officer, of the Corporation or 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 employee benefit plans, whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent authorized by the Delaware General
Corporation Law, 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 said law permitted
the Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid or to be paid in settlement) reasonably
incurred or suffered by such person in connection therewith 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 his or her heirs,
executors and administrators; provided, however, that, except as provided in
paragraph (b) hereof, 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 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: provided, however, that, if
the Delaware General Corporation Law requires, the payment of such expenses
incurred by a director or officer in his or her capacity as a director or
officer (and not in any other capacity in which service was or is rendered by
such person while a director or officer, including, without limitation, service
to an employee benefit plan) 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 Section or otherwise. The
Corporation may, by action of its Board of Directors, provide indemnification to
employees and agents of the Corporation with the same scope and effect as the
foregoing indemnification of directors and officers.

            (b) RIGHT OF CLAIMANT TO BRING SUIT:

      If a claim under paragraph (a) of this Section is not paid in full by the
Corporation within thirty 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 standards of conduct which make it 



permissible under the Delaware General 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 he or she has met the applicable standard of conduct set forth in the
Delaware General 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 or conduct,
shall be a defense to the action or create a presumption that the claimant has
not met the applicable standard or conduct.

            (c) Notwithstanding any limitation to the contrary contained in
sub-paragraphs (a) and 8 (b) of this section, the corporation shall, to the
fullest extent permitted by Section 145 of the General Corporation Law of the
State of Delaware, as the same may be amended and supplemented, indemnify any
and all persons whom it shall have power to indemnify under said section from
and against any and all of the expenses, liabilities or other matters referred
to in or covered by said section, and the indemnification provided for herein
shall not be deemed exclusive of any other rights to which those indemnified may
be entitled under any By-law, agreement, vote of stockholders or disinterested
Directors or otherwise, both as to action in his 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 director, officer, employee or agent and shall inure to the benefit
of the heirs, executors and administrators of such a person.

            (d) 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
Delaware General Corporation Law.

                            ARTICLE XII - AMENDMENTS

      Section 1. These By-Laws may be amended or repealed by the vote of
stockholders entitled to cast at least a majority of the votes which all
stockholders are entitled to cast thereon, at any regular or special meeting of
the stockholders, duly convened after notice to the stockholders of that
purpose.
