                            MEETINGS OF STOCKHOLDERS

         SECTION 1. PLACE OF MEETINGS. All meetings of stockholders for any
purpose shall be held at such place, within or without the State of Delaware, as
shall be designated by the Board of Directors or the Chairman of the Board or
the President and stated in the notice of the meeting. The Board of Directors
may, in its sole discretion, determine that a meeting of stockholders shall not
be held in any place but shall instead be held solely by means of remote
communication. If authorized by the Board of Directors in its sole discretion,
and subject to such guidelines and procedures as the Board of Directors may
adopt, stockholders not physically present at a meeting of stockholders may, by
means of remote communication, participate in a meeting of stockholders and be
deemed present in person and vote at a meeting of stockholders whether such
meeting is to be held at a designated place or solely by means of remote
communication, provided that (a) the Board of Directors shall implement
reasonable measures to verify that each person deemed present and permitted to
vote at the meeting by means of remote communication is a stockholder, (b) the
Board of Directors shall implement reasonable measures to provide such
stockholders a reasonable opportunity to participate in the meeting and to vote
on matters submitted to the stockholders, including an opportunity to read or
hear the proceedings of the meeting substantially concurrently with such
proceedings, and (c) if any stockholder votes or takes other action at the
meeting by means of remote communication, a record of such vote or other action
shall be maintained by the corporation.

         SECTION 2. ANNUAL MEETING. An annual meeting of the stockholders of the
corporation, for the election of Directors to succeed those whose terms expire
and for the transaction of such other business as may properly come before the
meeting, shall be held on such date and at such time as shall be fixed from time
to time by the Board of Directors and stated in the notice of the meeting.

         SECTION 3. SPECIAL MEETINGS. Special meetings of the stockholders may
be called by the Chairman of the Board, the President or by order of the Board
of Directors. Business transacted at any special meeting shall be confined to
the purpose or purposes stated in the notice of such meeting.

         SECTION 4. NOTICE OF MEETING. Whenever stockholders are required or
permitted to take any action at a meeting, a written notice of the meeting shall
be given which shall state the place, if any, date and hour of the meeting, the
means of remote communications, if any, by which stockholders may be deemed to
be present in person and vote at such meeting, and, in the case of a special
meeting, the purpose or purposes for which the meeting is called. Unless
otherwise required by law, the certificate of incorporation or these By-laws,
notice of the time and place of holding each annual meeting and each special
meeting of stockholders shall be given by the Secretary, not less than ten nor
more than sixty days before the meeting, to each stockholder of record entitled
to vote at such meeting.

         When a meeting is adjourned to another place, date or time, unless the
adjournment is for more than thirty days or a new record date is fixed for the
adjourned meeting, notice of the adjourned meeting need not be given if the
time, place, if any, thereof, and the means of remote communication, if any, by
which stockholders may be deemed to be present in person and vote at such
adjourned meeting are announced at the meeting at which the adjournment is
taken. At such adjourned meeting at which a quorum shall be present or
represented any business may be transacted which might have been transacted at
the meeting as originally called.

         SECTION 5. LIST OF STOCKHOLDERS. At least ten days before every meeting
of stockholders a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder,
shall be prepared by the Secretary, who shall have charge of the stock ledger.
Nothing contained in this Section 5 shall require the corporation to include
electronic mail addresses or other electronic contact information on such list.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, for a period of at least ten days prior to the meeting:
(i) on a reasonably accessible electronic network, provided that the information
required to gain access to such list is provided with the notice of the meeting,
or (ii) during ordinary business hours, at the principal place of business of
the corporation. In the event that the corporation determines to make the list
available on an electronic network, the corporation may take reasonable steps to
ensure that such information is available only to stockholders of the



                                       2
   3

corporation. If the meeting is to be held at a place, then the list shall be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present. If the meeting
is to be held solely by means of remote communication, then the list shall also
be open to the examination of any stockholder during the whole time of the
meeting on a reasonably accessible electronic network, and the information
required to access such list shall be provided with the notice of the meeting.
Except as otherwise provided by law, the stock ledger shall be the only evidence
as to who are the stockholders entitled to examine the stock ledger, the list of
stockholders or the books of the corporation, or to vote in person or by proxy
at any meeting of stockholders.

         SECTION 6. QUORUM. At any meeting of stockholders, the holders of
issued and outstanding shares of capital stock which represent a majority of the
votes entitled to be cast thereat, present in person or represented by proxy,
shall constitute a quorum for the transaction of business. If, however, such
quorum shall not be present or represented at any meeting of the stockholders,
then either the person presiding over the meeting or the stockholders entitled
to vote thereat, present in person or represented by proxy, shall have the power
to adjourn the meeting from time to time until a quorum shall be present or
represented.

         SECTION 7. VOTING. At any meeting of the stockholders, every
stockholder having the right to vote shall be entitled to vote in person, or by
proxy appointed by an instrument in writing subscribed by such stockholder and
bearing a date not more than eleven months prior to said meeting. When a quorum
is present at any meeting, a plurality of the votes properly cast for election
to the Board of Directors and a majority of the votes properly cast on any
question other than election to the Board of Directors shall decide the question
unless the question is one upon which by express provision of law or of the
certificate of incorporation or of these By-laws a different vote is required,
in which case such express provision shall govern and control the decision of
such question.

         SECTION 8.  FIXING OF RECORD DATE.

         (a) In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, 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 other than stockholder action by written consent, the Board
of Directors may fix a record date, which shall not precede the date such record
date is fixed and shall not be more than sixty nor less than ten days before the
date of such meeting, nor more than sixty days prior to any such other action.
If no record date is fixed, 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.
The record date for any other purpose other than stockholder action by written
consent shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or 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.



                                       3

         (b) In order that the corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the Board
of Directors 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 of
Directors, and which date shall not be more than ten days after the date upon
which the resolution fixing the record date is adopted by the Board of
Directors. Any stockholder of record seeking to have the stockholders authorize
or take corporate action by written consent shall, by written notice to the
Secretary, request the Board of Directors to fix a record date. The Board of
Directors shall promptly, but in all events within ten days after the date on
which such a request is received, adopt a resolution fixing the record date. If
no record date has been fixed by the Board of Directors within ten days of the
date on which such a request is received, the record date for determining
stockholders entitled to consent to corporate action in writing without a
meeting, when no prior action by the Board of Directors is required by
applicable law, 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 any officer or agent of the corporation having
custody of the book in which proceedings of meetings of stockholders are
recorded. Delivery made to the 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 of Directors and prior action by the Board of
Directors is required by applicable law, 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 date on which the Board of
Directors adopts the resolution taking such prior action.

         SECTION 9. NOMINATION OF DIRECTORS. Only persons who are nominated in
accordance with the procedures set forth in the By-laws shall be eligible to
serve as Directors. Nominations of persons for election to the Board of
Directors of the corporation may be made at a meeting of stockholders (a) by or
at the direction of the Board of Directors or (b) by any stockholder of the
corporation who is a stockholder of record at the time of giving of notice
provided for in this Section 9, who shall be entitled to vote for the election
of Directors at the meeting and who complies with the notice procedures set
forth in this Section 9. Such nominations, other than those made by or at the
direction of the Board of Directors, shall be made pursuant to timely notice in
writing to the Secretary of the corporation. To be timely, a stockholder's
notice shall be delivered to or mailed and received at the principal executive
offices of the corporation not less than 90 days prior to the meeting; provided,
however, that in the event that less than 100 days' notice or prior public
disclosure of the date of the meeting is given or made to stockholders, notice
by the stockholder to be timely must be so received not later than the close of
business on the tenth day following the day on which such notice of the date of
the meeting or such public disclosure was made. Such stockholder's notice shall
set forth (a) as to each person whom the stockholder proposes to nominate for
election or reelection as a Director all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
Directors, or is otherwise required, in each case pursuant to Regulation 14A
under the Securities Exchange Act of 1934, as amended (including such person's
written consent to being named in the proxy statement as a nominee and to



                                       4

serving as a Director if elected); and (b) as to the stockholder giving the
notice (i) the name and address, as they appear on the corporation's books, of
such stockholder and (ii) the class and number of shares of the corporation
which are beneficially owned by such stockholder. At the request of the Board of
Directors, any person nominated by the Board of Directors for election as a
Director shall furnish to the Secretary of the corporation that information
required to be set forth in a stockholder's notice of nomination which pertains
to the nominee. No person shall be eligible to serve as a Director of the
corporation unless nominated in accordance with the procedures set forth in this
By-law. The person presiding over the meeting shall, if the facts warrant,
determine and declare to the meeting that a nomination was not made in
accordance with the procedures prescribed by the By-laws, and if he or she
should so determine, he or she shall so declare to the meeting and the defective
nomination shall be disregarded. Notwithstanding the foregoing provisions of
this Section 9, a stockholder shall also comply with all applicable requirements
of the Securities Exchange Act of 1934, as amended, and the rules and
regulations thereunder with respect to the matters set forth in this Section.

         SECTION 10. NOTICE OF BUSINESS. At any meeting of the stockholders,
only such business shall be conducted as shall have been brought before the
meeting (a) by or at the direction of the Board of Directors or (b) by any
stockholder of the corporation who is a stockholder of record at the time of
giving of the notice provided for in this Section 10, who shall be entitled to
vote at such meeting and who complies with the notice procedures set forth in
this Section 10. For business to be properly brought before a stockholder
meeting by a stockholder, the business must relate to a proper subject matter
for stockholder action and the stockholder must have given timely notice thereof
in writing to the Secretary of the corporation. To be timely, a stockholder's
notice must be delivered to or mailed and received at the principal executive
offices of the corporation not less than 90 days prior to the meeting; provided,
however, that in the event that less than 100 days' notice or prior public
disclosure of the date of the meeting is given or made to stockholders, notice
by the stockholder, to be timely must be received no later than the close of
business on the 10th day following the day on which such notice of the date of
the meeting was mailed or such public disclosure was made. A stockholder's
notice to the Secretary shall set forth as to each matter the stockholder
proposes to bring before the meeting (a) a brief description of the business
desired to be brought before the meeting and the reasons for conducting such
business at the meeting, (b) the name and address, as they appear on the
corporation's books, of the stockholder proposing such business, (c) the class
and number of shares of the corporation which are beneficially owned by the
stockholder and (d) any material interest in the stockholder in such business.
Notwithstanding anything in the By-laws to the contrary, no business shall be
conducted at a stockholder meeting except in accordance with the procedures set
forth in this Section 10. The person presiding over the meeting shall, if the
facts warrant, determine and declare to the meeting that business was not
properly brought before the meeting and in accordance with the provisions of the
By-laws, and if he or she should so determine, he or she shall so declare to the
meeting and any such business not properly brought before the meeting shall not
be transacted. Notwithstanding the foregoing provisions of this Section 10, a
stockholder shall also comply with all applicable requirements of the Securities
Exchange Act of 1934, as amended, and the rules and regulations thereunder with
respect to the matters set forth in this Section.

have the right and authority to convene and adjourn the meeting, to prescribe
such rules, regulations and procedures and to do all such acts as, in the
judgment of the person presiding over the meeting, are necessary, appropriate or
convenient for the proper conduct of the meeting, including, without limitation,
establishing an agenda or order of business for the meeting, rules and
procedures for maintaining order at the meeting and the safety of those present,

meeting that a matter or business was not properly brought before the meeting
and if the person presiding over the meeting should so determine and declare,
any such matter or business shall not be transacted or considered. Unless and to
the extent determined by the Board of Directors or the person presiding over the
meeting, meetings of stockholders shall not be required to be held in accordance
with rules of parliamentary procedure.

of the Board or to the President or to the Secretary of the corporation; and any
member of any committee may resign upon notice given in writing or by electronic
transmission given either as aforesaid or to the committee of which he or she is

thereof, and, unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective. The Board of Directors



                                       10
   11

corporation entitled to vote generally in the election of Directors, and his or
her successor or their successors shall be elected by the remaining Directors as
provided in these By-laws in the filling of other vacancies. A Director may be

before the body proposing to remove him or her.

                                   ARTICLE VII

                INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

         SECTION 1. DIRECTORS AND OFFICERS. Subject to the provisions of Section
5, the corporation shall indemnify, to the fullest extent permitted by the
General Corporation Law of the State of Delaware as presently in effect or as
hereafter amended:

                  (a) 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
         and whether external or internal to the corporation (other than by
         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 or
         officer of another corporation, partnership, joint venture, trust or
         other enterprise, against expenses (including attorneys' fees),
         judgments, fines and amounts paid in settlement actually and reasonably
         incurred by him or her in connection with such suit, action or
         proceeding if he or she acted in good faith and in a manner which he or
         she reasonably believed to be in or not opposed to the best interests
         of the corporation, and, with respect to any criminal action or
         proceeding, had reasonable cause to believe that his or her conduct was
         unlawful. The termination of any action, suit or proceeding by
         judgment, order, settlement, conviction, or upon a plea of nolo
         contendere or its equivalent, shall not, of itself, create a
         presumption that the person did not act in good faith and in a manner
         which he or she reasonably believed to be in or not opposed to the best
         interests of the corporation, and, with respect to any criminal action
         or proceeding, had reasonable cause to believe that his or her conduct
         was lawful.



                                       11
   12

                  (b) 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 or officer of another corporation, partnership, joint
         venture, trust or other enterprise, against expenses (including
         attorneys' fees) and, to the extent permitted by law, amounts paid in
         settlement actually and reasonably incurred by him or her in connection
         with the defense or settlement of such action or suit if he or she
         acted in good faith and in a manner he or she reasonably believed to be
         in or not opposed to the best interests of the corporation and except
         that no indemnification shall be made in respect of any claim, issue or
         matter as to which such person shall have been adjudged to be liable to
         the corporation unless and only to the extent that the Court of
         Chancery of the State of Delaware or the court in which such action or
         suit was brought shall determine upon application that, despite the
         adjudication of liability but in view of all the circumstances of the
         case, such person is fairly and reasonably entitled to indemnity for
         such expenses which the Court of Chancery of the State of Delaware or
         such other court shall deem proper.

                  (c) In addition to and without limiting the foregoing
         provisions of this Article VII and except to the extent otherwise
         required by law, any person seeking indemnification under or pursuant
         to this Section 1 shall be deemed and presumed to have met the
         applicable standard of conduct set forth in this Section l unless the
         contrary shall be established, and the corporation shall have the
         burden of proof to overcome such prescription in connection with the
         making by any person or entity of any determination contrary to that
         presumption.

         SECTION 2. EMPLOYEES AND AGENTS. Subject to the provisions of Section
5, the Board of Directors, in its discretion, may authorize the corporation to
indemnify to the fullest extent permitted by the General Corporation Law of the
State of Delaware (as presently in effect or as hereafter amended):

                  (a) 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 an employee or agent of the
         corporation, or is or was serving at the request of the corporation as
         an employee or agent of another corporation, partnership, joint
         venture, trust or other enterprise, against expenses (including
         attorneys' fees), judgments, fines and amounts paid in settlement
         actually and reasonably incurred by him or her in connection with such
         suit, action or proceeding if he or she acted in good faith and in a
         manner he or she reasonably believed to be in or not opposed to the
         best interest of the corporation, and, with respect to any criminal
         action or proceeding, had no reasonable cause to believe his or her



                                       12
   13

         conduct was unlawful. The termination of any action, suit or proceeding
         by judgment, order, settlement, conviction, or upon a plea of nolo
         contendere or its equivalent, shall not, of itself, create a
         presumption that the person did not act in good faith and in a manner
         which he or she reasonably believed to be in or not opposed to the best
         interests of the corporation, and, with respect to any criminal action
         or proceeding, had reasonable cause to believe that his or her conduct
         was unlawful.

                  (b) 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 an employee or agent of
         the corporation, or is or was serving at the request of the corporation
         as an employee or agent of another corporation, partnership, joint
         venture, trust or other enterprise, against expenses (including
         attorneys' fees) and amounts, to the extent permitted by law, paid in
         settlement actually and reasonably incurred by him or her in connection
         with the defense or settlement of such action or suit if he or she
         acted in good faith and in a manner he or she reasonably believed to be
         in or not opposed to the best interests of the corporation and except
         that no indemnification shall be made in respect of any claim, issue or
         matter as to which such person shall have been adjudged to be liable to
         the corporation unless and only to the extent that the Court of
         Chancery of the State of Delaware or the court in which such action or
         suit was brought shall determine upon application that, despite the
         adjudication of liability but in view of all the circumstances of the
         case, such person is fairly and reasonably entitled to indemnity for
         such expenses which the Court of Chancery of the State of Delaware or
         such other court shall deem proper.

         SECTION 3. INDEMNIFICATION FOR EXPENSES OF SUCCESSFUL PARTY.
Notwithstanding the other provisions of this Article, to the extent that a
present or former Director or officer of the corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred to
in Section 1 or in Section 2 of this Article, or in defense of any claim, issue
or matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith. Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to such person, (ii) an
adjudication that such person was liable to the corporation, (iii) a plea of
guilty or nolo contendere by such person, (iv) an adjudication that such person
did not act in good faith and in a manner he or she reasonably believed to be in
or not opposed to the best interests of the corporation, and (v) with respect to
any criminal proceeding, an adjudication that such person had reasonable cause
to believe his or her conduct was unlawful, such person shall be considered for
the purposes hereof to have been wholly successful with respect thereto.

         SECTION 4. PROCEDURE. Any indemnification under this Article VII
(unless required by law or ordered by a court) shall be made by the corporation
only as authorized in the specific case upon a determination that
indemnification of the present or former Director, officer, employee or agent is
proper in the circumstances because he or she has met the applicable standard of
conduct set forth in Sections l and 2 of this Article VII. Such determination



                                       13
   14

shall be made, with respect to a person who is a Director or officer at the time
of such determination, (i) by a majority vote of the Directors who are not
parties to such action, suit or proceeding, even though less than a quorum or
(ii) by a committee of such Directors designated by majority vote of such
Directors, even though less than a quorum or (iii) if there are no such
Directors, or if such Directors so direct, by independent legal counsel in a
written opinion, or (iv) by the stockholders of the corporation.

         SECTION 5. NOTIFICATION AND DEFENSE OF CLAIM; RIGHT TO INSTITUTE SUIT.

         (a) In addition to and without limiting the foregoing provisions of
this Article VII and except to the extent otherwise required by law, it shall be
a condition of the corporation's obligation to indemnify under Sections l and 2
of this Article VII (in addition to any other condition in these By-laws or by
law provided or imposed) that the person asserting, or proposing to assert, the
right to be indemnified, must notify the corporation in writing as soon as
practicable of any action, suit, proceeding or investigation involving such
person for which indemnity will or could be sought, but the failure to so notify
shall not affect the corporation's objection to indemnify except to the extent
the corporation is adversely affected thereby. With respect to any action, suit,
proceeding or investigation of which the corporation is so notified, the
corporation will be entitled to participate therein at its own expense and/or to
assume the defense thereof at its own expense, with legal counsel reasonably
acceptable to such person. After notice from the corporation to such person of
its election so to assume such defense, the corporation shall not be liable to
such person for any legal or other expenses subsequently incurred by such person
in connection with such action, suit, proceeding or investigation other than as
provided below in this subsection (a). Such person shall have the right to
employ his or her own counsel in connection with such action, suit, proceeding
or investigation, but the fees and expenses of such counsel incurred after
notice from the corporation of its assumption of the defense thereof shall be at
the expense of such person unless (i) the employment of counsel by such person
has been authorized by the corporation, (ii) counsel to such person shall have
reasonably concluded that there may be a conflict of interest or position on any
significant issue between the corporation and such person in the conduct of the
defense of such action, suit, proceeding or investigation or (iii) the
corporation shall not in fact have employed counsel to assume the defense of
such action, suit, proceeding or investigation, in each of which cases the fees
and expenses of counsel for such person shall be at the expenses of the
corporation, except as otherwise expressly provided by this Article VII. The
corporation shall not be entitled, without the consent of such person, to assume
the defense of any claim brought by or in the right of the corporation or as to
which counsel for such person shall have reasonably made the conclusion provided
for in clause (ii) above. The corporation shall not be required to indemnify
such person under this Article VII for any amounts paid in settlement of any
action, suit, proceeding or investigation effected without its written consent.
The corporation shall not settle any action, suit, proceeding or investigation
in any manner which would impose any penalty or limitation on such person
without such person's written consent. Neither the corporation nor such person
will unreasonably withhold their consent to any proposed settlement.



                                       14
   15


         (b) If a claim for indemnification or advancement of expenses under
this Article VII is not paid in full by the corporation within 90 days after a
written claim therefor 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 expenses of prosecuting such claim.

         SECTION 6. REDUCTION AND REIMBURSEMENT. The corporation's
indemnification under Sections 1 and 2 of this Article VII 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, partnership, joint venture, trust or other
enterprise, shall be reduced by any amounts such person receives as
indemnification (i) under any policy of insurance purchased and maintained on
his or her behalf by the corporation, (ii) from such other corporation,
partnership, joint venture, trust or other enterprise, or (iii) under any other
applicable indemnification provision. In the event the corporation makes an
indemnification payment under this Article VII and the person receiving such
payment is subsequently reimbursed from the proceeds of insurance or by such
other corporation, partnership, joint venture, trust or other enterprise, such
person shall promptly refund such indemnification payments to the corporation to
the extent of such reimbursement.

         SECTION 7. ADVANCE OF EXPENSES. In the event that the corporation does
not assume the defense pursuant to Section 5, any expenses (including attorneys'
fees) incurred by a Director or officer in defending any civil, criminal,
administrative or investigative action, suit or proceeding 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 or
officer to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the corporation as authorized in
this Article VII. Any advance under this Section 4 shall be made promptly, and
in any event within ninety days, upon the written request of the person seeking
the advance.

         SECTION 8. INSURANCE. The corporation may 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, partnership,
joint venture, trust or other enterprise, against any liability asserted against
such person and incurred by such person in any such capacity, or arising out of
such person's status as such, whether or not the corporation would have the
power to indemnify such person against such liability under the provisions of
the General Corporation Law of the State of Delaware (as presently in effect or
hereafter amended), the certificate of incorporation of the corporation or these
By-laws.

         SECTION 9. CONSOLIDATION OR MERGER. In the discretion of the Board of
Directors of the corporation, for the purposes of this Article VII, references
to "the corporation" may also include 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 or officers, so that any person who is or was a Director



                                       15
   16

or officer of such constituent corporation, or is or was serving at the request
of such constituent corporation as a Director or officer of another corporation,
partnership, joint venture, trust or other enterprise, would stand in the same
position under the provisions of this Article VII with respect to the resulting
or surviving corporation as he or she would have with respect to such other
constituent corporation if its separate existence had continued.

         SECTION 10. NON-EXCLUSIVE; SAVINGS CLAUSE. The indemnification and
advancement of expenses provided by, or granted pursuant to, the other Sections
of this Article VII shall not be deemed exclusive of any other rights to which
any person, whether or not entitled to be indemnified under this Article VII,
may be entitled under any statute, by-law, agreement, vote of stockholders or
disinterested Directors or otherwise, both as to action in such person's
official capacity and as to action in another capacity while holding such
office. Each person who is or becomes a Director or officer as described in
Section 1 shall be deemed to have served or to have continued to serve in such
capacity in reliance upon the indemnity provided for in this Article VII. All
rights to indemnification under this Article VII shall be deemed to be provided
by a contract between the corporation and the person who serves as a Director or
officer of the corporation at any time while these By-laws and other relevant
provisions of the General Corporation Law of the State of Delaware and other
applicable law, if any, are in effect. Any repeal or modification thereof shall
not affect any rights or obligations then existing.

         SECTION 11. INUREMENT. The indemnification and advancement of expenses
provided by, or granted pursuant to, this Article VII 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 a
person.

         SECTION 12. DEFINITIONAL MATTERS. For purposes of this Article VII,
references to "other enterprises" shall include employee benefit plans;
references to "fines" shall include any excise taxes assessed on a person with
respect to any employee benefit plan; and references to "serving at the request
of the corporation" shall include any service by a Director or officer of the
corporation which imposes duties on, or involves services by, such person with
respect to any employee benefit plan, its participants, or beneficiaries; and a
person who acted in good faith and in a manner he or she reasonably believed to
be in the interest of the participants and beneficiaries of an employee benefit
plan shall be deemed to have acted in a manner "not opposed to the best
interests of the corporation" as referred to in this Article VII.

                                  ARTICLE VIII

                                  CAPITAL STOCK

         SECTION 1. STOCK CERTIFICATES. Each stockholder shall be entitled to a
certificate or certificates representing in the aggregate the share owned by him
or her and certifying the number and class thereof, which shall be in such form
as this Board shall adopt. Each certificate of stock shall be signed by the
Chairman of the Board or the President or a Vice President, and by the Treasurer
or an Assistant Treasurer or the Secretary or an Assistant Secretary. Any of or
all the signatures on the certificate may be a facsimile. In case any officer,



                                       16
   17

transfer agent or registrar who has signed or whose facsimile signature has been
placed upon a certificate has ceased to be such officer, transfer agent or
registrar before the certificate is issued, such certificate may nevertheless be
issued by the corporation with the same effect as if he or she were such
officer, transfer agent or registrar at the date of issue.

         SECTION 2. TRANSFER OF STOCK. Shares of stock shall be transferable on
the books of the corporation pursuant to applicable law and such rules and
regulations as the Board of Directors shall from time to time prescribe.

         SECTION 3. HOLDERS OF RECORD. Prior to due presentment for registration
of transfer the corporation may treat the holder of record of a share of its
stock as the complete owner thereof exclusively entitled to vote, to receive
notifications and otherwise entitled to all the rights and powers of a complete
owner thereof, notwithstanding notice to the contrary.

         SECTION 4. TRANSFER AGENT AND REGISTRAR. The Board of Directors may at
any time appoint a transfer agent or agents and/or registrar or registrars for
the transfer and/or registration of shares of stock.

         SECTION 5. LOST, STOLEN, DESTROYED OR MUTILATED STOCK CERTIFICATES. The
Board of Directors may direct a new stock certificate or certificates to be
issued in place of any certificate or certificates theretofore issued by the
corporation alleged to have been lost, stolen, destroyed or mutilated, upon the
making of an affidavit of that fact by the person claiming the certificate of
stock to be lost, stolen, destroyed or mutilated. 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, destroyed or mutilated certificate or certificates, or his or her
legal representative, to (a) advertise the same in such manner as it shall
require and/or (b) 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, destroyed or
mutilated and/or (c) comply with any other reasonable requirements prescribed by
the Board.

                                   ARTICLE IX

                        SECURITIES OF OTHER CORPORATIONS

substitution) to act in the name and on behalf of the corporation (as proxy or
otherwise), at any meeting of the holders of stock or other securities of any

   18

corporation or other organization, securities of which shall be held by this
corporation, or (ii) express consent or dissent, as a holder of such securities,
to corporate or other action by such other corporation or organization.

for such other purpose as the Directors shall think conducive to the interest of
the corporation, and the Directors may modify or abolish any such reserve in the

stockholders given by the corporation under any provision of law, the
certificate of incorporation, or these By-laws shall be effective if given by a
form of electronic transmission consented to by the stockholder to whom the
notice is given. Any such consent shall be revocable by the stockholder by
written notice to the corporation. Any such consent shall be deemed revoked if
(a) the corporation is unable to deliver by electronic transmission two
consecutive notices given by the corporation in accordance with such consent and
(b) such inability becomes known to the Secretary or an Assistant Secretary of
the corporation or to the transfer agent, or other person responsible for the
giving of notice; provided, however, the inadvertent failure to treat such
inability as a revocation shall not invalidate any meeting or other action.

         Notice given pursuant to the immediately preceding paragraph shall be
deemed given: (a) if by facsimile telecommunication, when directed to a number
at which the stockholder has consented to receive notice; (b) if by electronic
mail, when directed to an electronic mail address at which the stockholder has
consented to receive notice; (c) if by a posting on an electronic network
together with separate notice to the stockholder of such specific posting, upon
the later of (i) such posting and (ii) the giving of such separate notice; and
(d) if by any other form of electronic transmission, when directed to the
stockholder. An affidavit of the Secretary or any Assistant Secretary or of the
transfer agent or other agent of the corporation that the notice has been given
by a form of electronic transmission shall, in the absence of fraud, be PRIMA
FACIE evidence of the facts stated therein.

         For purposes of these By-laws, "electronic transmission" means any form
of communication, not directly involving the physical transmission of paper,
that creates a record that may be retained, retrieved and reviewed by a

recipient thereof, and that may be directly reproduced in paper form by such a
recipient through an automated process.

         SECTION 2. WAIVER OF NOTICE. Whenever notice is required, the
certificate of incorporation, these By-laws or as otherwise provided by law, a
written waiver thereof, signed by the person entitled to notice, or a waiver by
electronic transmission by the person entitled to notice, whether before or
after the time stated therein, shall be deemed equivalent to notice. Attendance
of a person at a meeting shall constitute a waiver of notice of such meeting
except when the person 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. Neither the business to be
transacted at, nor the purpose of, any regular or special meeting of the
stockholders, Directors or members of a committee of directors need be specified
in any written waiver of notice or any waiver by electronic transmission.

                                   ARTICLE XVI

                                  SEVERABILITY

         If any term or provision of the By-laws, or the application thereof to
any person or circumstance or period of time, shall to any extent be invalid or
unenforceable, the remainder of the By-laws, or the application of such term or
provision to persons or circumstances or periods of time other than those as to
which it is invalid or unenforceable, shall not be affected thereby and each
term and provision of the By-laws shall be valid and enforced to the fullest
extent permitted by law. All restrictions, limitations, requirements and other
provisions of these By-laws shall be construed, insofar as possible, as
supplemental and additional to all provisions of law applicable to the subject
matter thereof and shall be fully complied with in addition to the said
provisions of law unless such compliance shall be contrary to law.

                                  ARTICLE XVII

                                   AMENDMENTS

         The Board of Directors and the stockholders shall each have the power
to adopt, alter, amend and repeal these By-laws, and any By-laws adopted by the
Directors or the stockholders under the powers conferred hereby may be altered,
amended or repealed by the Directors or by the stockholders; provided, however,
that these By-laws shall not be altered, amended or repealed by action of the
stockholders, and no By-law shall be adopted by action of the stockholders,
without the affirmative vote of the holders of at least seventy-five percent
(75%) of the voting power of all the shares of the corporation entitled to vote
generally in the election of Directors, voting together as a single class.

         The above Amended and Restated By-laws are effective as of May 18,
2001, the date of their adoption by the Board of Directors of Nabi.
