represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented. At such adjourned
meeting at which a quorum shall be present or represented any business

notified. 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

                 Section 9.        When a quorum is present at any meeting, the 
vote of the holders of a majority of the stock having voting power present in
person or represented by proxy shall decide any question brought before such
meeting unless the question is one upon which, by express provision of the

in which case such express provision shall govern and control the decision of
such question.

                 Section 10.      Unless otherwise provided in the certificate

                INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS

         (a)     Indemnification in Actions Other Than Those Brought by the
Corporation. The corporation shall indemnify and hold harmless, to the
fullest extent permitted by the Delaware General Corporation Law, as the same
exists or may hereafter be amended (but, in the case of such amendment, only to
the extent that such amendment permits the corporation to provide broader
indemnification rights than such law permitted the corporation to provide prior
to such amendment), 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,
whether civil, criminal, administrative or investigative (other than an action
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 is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding. Except as provided in 


N.E.T. BY-LAWS                         19              AS AMENDED AUGUST 8, 1995
   21
paragraph (d) of this Section 6, the corporation shall be required to
indemnify a person in connection with a proceeding (or part thereof) initiated
by such person only if the proceeding (or part thereof) was authorized by the
Board of Directors of the corporation.

         (b)     Indemnification in Actions Brought By or on Behalf of the 
Corporation. The corporation shall indemnify and hold harmless, to the fullest
extent permitted by the Delaware General Corporation Law, as the same exists or
may hereafter be amended, any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit 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 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, against expenses (including attorney's fees)
actually and reasonably incurred by him or her in connection with the defense or
settlement of such action or suit.

         (c)     Expenses; Prepayment. The corporation shall pay the
expenses (including attorneys' fees) incurred by a director or officer who has
been successful on the merits or otherwise in defending any action, suit or
proceeding referenced in paragraphs (a) and (b) of this Section 6 and shall pay
such expenses in advance of the final disposition of such matter upon receipt of
an undertaking by the director or officer to repay all amounts advanced if it
should be ultimately determined that the director or officer is not entitled to
be indemnified under this Article or otherwise.

         (d)     Indemnification Procedure; Claims. Any indemnification
under paragraphs (a) and (b) of this Section 


N.E.T. BY-LAWS                         20              AS AMENDED AUGUST 8, 1995

6 (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
director or office is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in paragraphs (a) and (b). If a claim
for indemnification or payment of expenses under Section 6 of this Article is
not paid in full within sixty days after a written claim therefor has been
received by the corporation, the claimant may file suit to recover the unpaid
amount of such claim and, if successful in whole or in part, shall be entitled
to be paid the expense of prosecuting such claim.

         (e)     Indemnification of Others. The Board of Directors, in its
discretion, shall have the power on behalf of the corporation to indemnify any
person, other than a director or officer, made a party to any action, suit or
proceeding by reason of the fact that he or she, or his or her testator or
intestate, is or was an employee or agent of the corporation and to pay the
expenses incurred by any such person in defending such action, suit or
proceeding in advance of its final disposition.

         (f)     Non-exclusivity of Rights. The indemnification and
advancement of expenses provided by or granted pursuant to Section 6 of this
Article VII shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
bylaw, 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.

         (g)     Other Indemnification. The corporation's obligation, if
any, to indemnify any person who was or is serving at its request as a director,
officer, employee or 


N.E.T. BY-LAWS                         21              AS AMENDED AUGUST 8, 1995
   23
agent of another corporation, partnership, joint venture, trust, enterprise or
nonprofit entity shall be reduced by any amount such person may collect as
indemnification from such other corporation, partnership, joint venture, trust,
enterprise or nonprofit enterprise.

         (h)     Insurance. The corporation shall have the power to purchase
and maintain insurance on behalf of any person who is or was a director,
officer, employee or agent of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation against any liability asserted against him or her and incurred by
him or her in such capacity, or arising out of his or her status as such,
whether or not the corporation would have the power to indemnify him or her
against such liability under the provisions of this Section 6.

         (i)     Successor Entities. For purposes of Section 6 of this
Article VII, references to "the corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued would have had power and authority to indemnify its
directors, officers, employees and agents so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation shall stand in the same
position under the provisions of this Section 6 of Article VII with respect to
the resulting or surviving corporation as he or she would have with respect to
such constituent corporation if its separate existence had continued.

         (j)     Survival of Rights; Amendment or Repeal. The
indemnification and advancement of expenses provided by, or granted pursuant to
this Article VII shall, unless otherwise provided when authorized or ratified,
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 a person. Any repeal or modification of the foregoing provisions of
Section 6 of this Article VII shall not adversely affect any right or protection
hereunder of any person in respect of any act or omission occurring prior to the
time of such repeal or modification.

                                  ARTICLE VIII

                 Section 1.        These By-Laws may be altered, amended or 
repealed or new By-Laws may be adopted by the stockholders or by the Board of
Directors pursuant to the provisions of 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 By-Laws be contained in
