          ----------------

          The Board of Directors shall fix the location of the principal
executive office of the corporation at any place within or outside the State of

the corporation has one or more business offices in such state, then the Board
of Directors shall fix and designate a principal business office in the State of
Delaware.

     1.2  Other Offices.
          -------------

          The Board of Directors may at any time establish other offices at any
place or places where the corporation is qualified to do business.

                            MEETINGS OF STOCKHOLDERS
                            ------------------------

     2.1  Place Of Meetings.
          -----------------

          Meetings of stockholders shall be held at any place, within or outside
the State of Delaware, designated by the Board of Directors. In the absence of
any such designation, stockholders' meetings shall be held at the registered
office of the corporation.

     2.2  Annual Meeting.
          --------------

          The annual meeting of stockholders shall be held on such date, time
and place, either within or without the State of Delaware, as may be designated
by resolution of the Board of Directors each year. At the meeting, directors
shall be elected and any other proper business may be transacted.

     2.3  Special Meeting.
          ---------------

          A special meeting of the stockholders may be called at any time by the
Board of Directors, the chairman of the board, the president or by one or more
stockholders holding shares in the aggregate entitled to cast not less than ten
percent of the votes at that meeting.

          If a special meeting is called by any person or persons other than the
Board of Directors, the president or the chairman of the board, the request
shall be in writing, specifying



the time of such meeting and the general nature of the business proposed to be
transacted, and shall be delivered personally or sent by registered mail or by
telegraphic or other facsimile transmission to the chairman of the board, the
president, any vice president, or the secretary of the corporation. No business
may be transacted at such special meeting otherwise than specified in such
notice. The officer receiving the request shall cause notice to be promptly
given to the stockholders entitled to vote, in accordance with the provisions of
Sections 2.4 and 2.5 of this Article II, that a meeting will be held at the time
requested by the person or persons calling the meeting, not less than
thirty-five (35) nor more than sixty (60) days after the receipt of the request.
If the notice is not given within twenty (20) days after the receipt of the
request, the person or persons requesting the meeting may give the notice.
Nothing contained in this paragraph of this Section 2.3 shall be construed as
limiting, fixing, or affecting the time when a meeting of stockholders called by
action of the Board of Directors may be held.

     2.4  Notice Of Stockholders' Meetings.
          --------------------------------

          All notices of meetings with stockholders shall be in writing and
shall be sent or otherwise given in accordance with Section 2.5 of these Bylaws
not less than ten (10) nor more than sixty (60) days before the date of the
meeting to each stockholder entitled to vote at such meeting. The notice shall
specify the place (if any), date and hour of the meeting, and in the case of a
special meeting, the purpose or purposes for which the meeting is called.

     2.5  Manner Of Giving Notice; Affidavit Of Notice.
          --------------------------------------------

          Written notice of any meeting of stockholders, if mailed, is given
when deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation.
Without limiting the manner by which notice otherwise may be given effectively
to stockholders, any notice to stockholders may be given by electronic mail or
other electronic transmission, in the manner provided in Section 232 of the
Delaware General Corporation Law. An affidavit of the secretary or an assistant
secretary or of the transfer agent of the corporation that the notice has been
given shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.

     2.6  Quorum.
          ------

          The holders of a majority of the shares of stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation. If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (a) the chairman of
the meeting or (b) holders of a majority of the shares of stock entitled to vote
who are present, in person or by proxy, shall have power to adjourn the meeting
to another place (if any), date or time.

     2.7  Adjourned Meeting; Notice.
          -------------------------

          When a meeting is adjourned to another place (if any), date or time,
unless these Bylaws otherwise require, notice need not be given of the adjourned
meeting if the time and place

                                      -2-



(if any), thereof and the means of remote communications, if any, by which
stockholders and proxyholders may be deemed to be present and vote at such
adjourned meeting, are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or a new record date is affixed for the adjourned
meeting, notice of the place (if any), date and time of the adjourned meeting
and the means of remote communications, if any, by which stockholders and proxy
holders may be deemed to be present in person and vote at such adjourned meeting
shall be given to each stockholder of record entitled to vote at the meeting.

     2.8   Organization; Conduct of Business.
           ---------------------------------

           (a)  Such person as the Board of Directors may have designated or, in
the absence of such a person, the President of the Corporation or, in his or her
absence, such person as may be chosen by the holders of a majority of the shares
entitled to vote who are present, in person or by proxy, shall call to order any
meeting of the stockholders and act as Chairman of the meeting. In the absence
of the Secretary of the Corporation, the Secretary of the meeting shall be such
person as the Chairman of the meeting appoints.

           (b)  The Chairman of any meeting of stockholders shall determine the
order of business and the procedure at the meeting, including the manner of
voting and the conduct of business. The date and time of opening and closing of
the polls for each matter upon which the stockholders will vote at the meeting
shall be announced at the meeting.

     2.9   Voting.
           ------

           The stockholders entitled to vote at any meeting of stockholders
shall be determined in accordance with the provisions of Section 2.12 of these
Bylaws, subject to the provisions of Sections 217 and 218 of the General
Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors
and joint owners of stock and to voting trusts and other voting agreements).

           Except as may be otherwise provided in the certificate of
incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder. All elections shall be determined by a
plurality of the votes cast, and except as otherwise required by law, all other
matters shall be determined by a majority of the votes cast affirmatively or
negatively.

     2.10  Waiver Of Notice.
           -----------------

           Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
or waiver by electronic mail or other electronic transmission by such person,
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

                                      -3-



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 need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these Bylaws.

     2.11  Stockholder Action By Written Consent Without A Meeting.
           -------------------------------------------------------

           Unless otherwise provided in the certificate of incorporation, any
action required to be taken at any annual or special meeting of stockholders of
the corporation, or any action that may be taken at any annual or special
meeting of such stockholders, may be taken without a meeting, without prior
notice, and without a vote if a consent in writing, setting forth the action so
taken, is (i) signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted, and (ii) delivered to the Corporation in accordance with Section
228(a) of the Delaware General Corporation Law.

           Every written consent shall bear the date of signature of each
stockholder who signs the consent and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty (60) days of
the date the earliest dated consent is delivered to the Corporation, a written
consent or consents signed by a sufficient number of holders to take action are
delivered to the Corporation in the manner prescribed in this Section. A
telegram, cablegram, electronic mail or other electronic transmission consenting
to an action to be taken and transmitted by a stockholder or proxyholder, or by
a person or persons authorized to act for a stockholder or proxyholder, shall be
deemed to be written, signed and dated for purposes of this Section to the
extent permitted by law. Any such consent shall be delivered in accordance with
Section 228(d)(1) of the Delaware General Corporation Law.

           Any copy, facsimile or other reliable reproduction of a consent in
writing may be substituted or used in lieu of the original writing for any and
all purposes for which the original writing could be used, provided that such
copy, facsimile or other reproduction shall be a complete reproduction of the
entire original writing.

           Prompt notice of the taking of the corporate action without a meeting
by less than unanimous written consent shall be given to those stockholders who
have not consented in writing (including by electronic mail or other electronic
transmission as permitted by law). If the action which is consented to is such
as would have required the filing of a certificate under any section of the
General Corporation Law of Delaware if such action had been voted on by
stockholders at a meeting thereof, then the certificate filed under such section
shall state, in lieu of any statement required by such section concerning any
vote of stockholders, that written notice and written consent have been given as
provided in Section 228 of the General Corporation Law of Delaware.

     2.12  Record Date For Stockholder Notice; Voting; Giving Consents.
           -----------------------------------------------------------

           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 express

                                      -4-



consent to 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 shall not be more than sixty (60) nor
less than ten (10) days before the date of such meeting, nor more than sixty
(60) days prior to any other action.

           If the Board of Directors does not so fix a record date:

           (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 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 (including consent by electronic mail or other electronic transmission
as permitted by law) is delivered to the corporation.

           (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.

           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,
if such adjournment is for thirty (30) days or less; provided, however, that the
Board of Directors may fix a new record date for the adjourned meeting.

     2.13  Proxies.
           -------

           Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action in writing without a meeting may
authorize another person or persons to act for such stockholder by an instrument
in writing or by an electronic transmission permitted by law filed with the
secretary of the corporation, but no such proxy shall be voted or acted upon
after three (3) years from its date, unless the proxy provides for a longer
period. A proxy shall be deemed signed if the stockholder's name is placed on
the proxy (whether by manual signature, typewriting, telegraphic transmission or
otherwise) by the stockholder or the stockholder's attorney-in-fact. The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
Delaware.

                                    ---------

     3.1  Powers.
          ------

          Subject to the provisions of the General Corporation Law of Delaware
and any limitations in the certificate of incorporation or these Bylaws relating
to action required to be approved by the stockholders or by the outstanding
shares, the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the Board of
Directors.

     3.2  Number Of Directors.
          -------------------

          Upon the adoption of these bylaws, the number of directors
constituting the entire Board of Directors shall be six. Thereafter, this number
may be changed by a resolution of the Board of Directors or of the stockholders,
subject to Section 3.4 of these Bylaws. No reduction of the authorized number of
directors shall have the effect of removing any director before such director's
term of office expires.

     3.3  Election, Qualification And Term Of Office Of Directors.
          -------------------------------------------------------

          Except as provided in Section 3.4 of these Bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Directors need not be stockholders unless so required by the
certificate of incorporation or these Bylaws, wherein other qualifications for
directors may be prescribed. Each director, including a director elected to fill
a vacancy, shall hold office until his or her successor is elected and qualified
or until his or her earlier resignation or removal.

          Elections of directors need not be by written ballot.

     3.4  Resignation And Vacancies.
          -------------------------

          Any director may resign at any time upon written notice to the
attention of the Secretary of the corporation. When one or more directors so
resigns and the resignation is effective at a future date, a majority of the
directors then in office, including those who have so resigned, shall have power
to fill such vacancy or vacancies, the vote thereon to take effect when such
resignation or resignations shall become effective, and each director so chosen
shall hold office as provided in this section in the filling of other vacancies.

          Unless otherwise provided in the certificate of incorporation or these
Bylaws:

          (a)  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

          (b) Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

          If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these Bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

          If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole board (as constituted immediately prior to any such increase), then
the Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten (10) percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

the Board of Directors, may participate in a meeting of the Board of Directors,
or any committee, by means of conference telephone or other communications
equipment by means of which all persons participating in the meeting can hear

person at the meeting.

     3.6  Regular Meetings.
          ----------------

          Regular meetings of the Board of Directors may be held without notice
at such time and at such place as shall from time to time be determined by the

                                      -7-



           Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally by
facsimile, by electronic transmission, by telephone or by telegram, it shall be
delivered at least forty-eight (48) hours before the time of the holding of the
meeting. Any oral notice given personally or by telephone may be communicated
either to the director or to a person at the office of the director who the
person giving the notice has reason to believe will promptly communicate it to
the director. The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation. Unless otherwise indicated in the notice thereof, any and all
business may be transacted at a special meeting.

     3.8   Quorum.
           ------

           At all meetings of the Board of Directors, a majority of the total
number of directors shall constitute a quorum for the transaction of business
and the act of a majority of the directors present at any meeting at which there
is a quorum shall be the act of the Board of Directors, except as may be
otherwise specifically provided by statute or by the certificate of
incorporation. If a quorum is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

           A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

     3.9   Waiver Of Notice.
           ----------------

           Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the certificate of incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
or waiver by electronic mail or other electronic transmission by such person,
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 directors, or members of a committee of directors, need be specified in
any written waiver of notice unless so required by the certificate of
incorporation or these Bylaws.

     3.10  Board Action By Written Consent Without A Meeting.
           -------------------------------------------------

           Unless otherwise restricted by the certificate of incorporation or
these Bylaws, any action required or permitted to be taken at any meeting of the
Board of Directors, or of any committee thereof, may be taken without a meeting
if all members of the board or committee, as

                                      -8-



the case may be, consent thereto in writing or by electronic transmission, and
the writing or writings or electronic transmission or transmissions are filed
with the minutes of proceedings of the board or committee. Such filing shall be
in paper form if the minutes are maintained in paper form and shall be in
electronic form if the minutes are maintained in electronic form.

           Any copy, facsimile or other reliable reproduction of a consent in
writing may be substituted or used in lieu of the original writing for any and
all purposes for which the original writing could be used, provided that such
copy, facsimile or other reproduction shall be a complete reproduction of the
entire original writing.

therefor.

           The corporation may lend money to, or guarantee any obligation of, or

subsidiary, including any officer or employee who is a director of the
corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation. Nothing in this section contained shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

incorporation or by these Bylaws, any director or the entire Board of Directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that if the stockholders of the corporation are entitled to cumulative voting,
if less than the entire Board of Directors is to be removed, no director may be
removed without cause if the votes cast against his removal would be sufficient
to elect him if then cumulatively voted at an election of the entire Board of
Directors.

           No reduction of the authorized number of directors shall have the
effect of removing any director prior to the expiration of such director's term
of office.

resolution of the Board of Directors or by resolution of the committee, that
special meetings of committees may also be called by resolution of the Board of
Directors and that notice of special meetings of committees shall also be given

permitted by the General Corporation Law of Delaware, indemnify each of its
directors and officers against expenses (including attorneys' fees), judgments,
fines, settlements and other amounts actually and reasonably incurred in
connection with any proceeding, arising by reason of the fact that such person
is or was an agent of the corporation. For purposes of this Section 6.1, a
"director" or "officer" of the corporation includes any person (a) who is or was
a director or officer of the corporation, (b) who is or was serving at the
request of the corporation as a director or officer of another corporation,

manner permitted by the General Corporation Law of Delaware, to indemnify each
of its employees and agents (other than directors and officers) against expenses
(including attorneys' fees), judgments, fines, settlements and other amounts
actually and reasonably incurred in connection with any proceeding, arising by

agent of the corporation, (b) who 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, or (c) who was an employee or agent of a
corporation which was a predecessor corporation of the corporation or of another
enterprise at the request of such predecessor corporation.

     6.3  Payment Of Expenses In Advance.
          ------------------------------

          Expenses incurred in defending any action or proceeding for which
indemnification is required pursuant to Section 6.1 or for which indemnification
is permitted pursuant to Section 6.2 following authorization thereof by the
Board of Directors shall be paid by the corporation in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by or on
behalf of the indemnified party to repay such amount if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal that the indemnified party is not entitled to be indemnified as
authorized in this Article VI.

     6.4  Indemnity Not Exclusive.
          -----------------------

          The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be

directors or otherwise, both as to action in an

                                      -14-



official capacity and as to action in another capacity while holding such
office, to the extent that such additional rights to indemnification are
authorized in the certificate of incorporation

          ---------

          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,

employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any 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 the General Corporation Law of
Delaware.

     6.6  Conflicts.
          ---------

          No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

          (a) That it would be inconsistent with a provision of the certificate
of incorporation, these Bylaws, a resolution of the stockholders or an agreement
in effect at the time of the accrual of the alleged cause of the action asserted
in the proceeding in which the expenses were incurred or other amounts were
paid, which prohibits or otherwise limits indemnification; or

          (b) That it would be inconsistent with any condition expressly imposed
by a court in approving a settlement.

shall, upon written demand under oath stating the purpose thereof, have the
right during the usual hours for business to inspect for any proper purpose the
corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder. In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder. The demand under

                                      -15-



oath shall be directed to the corporation at its registered office in Delaware
or at its principal place of business.

          A complete list of stockholders entitled to vote at any meeting of
stockholders, arranged in alphabetical order for each class of stock and showing
the address of each such stockholder and the number of shares registered in each
such stockholder's name, shall be open to the examination of any such
stockholder for a period of at least ten (10) days prior to the meeting in the
manner provided by law. The stock list shall also be open to the examination of
any stockholder during the whole time of the meeting as provided by law. This
list shall presumptively determine the identity of the stockholders entitled to
vote at the meeting and the number of shares held by each of them.

     7.2  Inspection By Directors.

          Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his or her position as a director. The Court of
Chancery is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought. The Court may summarily order the
corporation to permit the director to inspect any and all books and records, the
stock ledger, and the stock list and to make copies or extracts therefrom. The
Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the Board of Directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

                                      -16-



     8.3  Stock Certificates; Partly Paid Shares.
          --------------------------------------

          The shares of a corporation shall be represented by certificates,
provided that the Board of Directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the Board of
Directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the Board of Directors, or the president or vice-president, and by the treasurer
or an assistant treasurer, or the secretary or an assistant secretary of such
corporation representing the number of shares registered in certificate form.
Any or all of the signatures on the certificate may be a facsimile. In case any
officer, 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 such certificate is issued, it may 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.

          The corporation may issue the whole or any part of its shares as
partly paid and subject to call for the remainder of the consideration to be
paid therefor. Upon the face or back of each stock certificate issued to
represent any such partly paid shares, upon the books and records of the
corporation in the case of uncertificated partly paid shares, the total amount
of the consideration to be paid therefor and the amount paid thereon shall be
stated. Upon the declaration of any dividend on fully paid shares, the
corporation shall declare a dividend upon partly paid shares of the same class,
but only upon the basis of the percentage of the consideration actually paid
thereon.

     8.4  Special Designation On Certificates.
          -----------------------------------

          If the corporation is authorized to issue more than one class of stock
or more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

     8.5  Lost Certificates.
          -----------------

          Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The corporation
may issue a new certificate of stock or

                                      -17-



uncertificated shares in the place of any certificate previously issued by it,
alleged to have been lost, stolen or destroyed, and the corporation may require
the owner of the lost, stolen or destroyed certificate, or the owner's legal
representative, to give the corporation a bond sufficient to indemnify it
against any claim that may be made against it on account of the alleged loss,
theft or destruction of any such certificate or the issuance of such new
certificate or uncertificated shares.

     8.6  Construction; Definitions.
          -------------------------

          Unless the context requires otherwise, the general provisions, rules
of construction, and definitions in the Delaware General Corporation Law shall
govern the construction of these Bylaws. Without limiting the generality of this
provision, the singular number includes the plural, the plural number includes
the singular, and the term "person" includes both a corporation and a natural
person.

     8.7  Dividends.
          ---------

          The directors of the corporation, subject to any restrictions
contained in (a) the General Corporation Law of Delaware or (b) the certificate
of incorporation, may declare and pay dividends upon the shares of its capital
stock. Dividends may be paid in cash, in property, or in shares of the
corporation's capital stock.

          The directors of the corporation may set apart out of any of the funds
of the corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

     8.8  Fiscal Year.
          -----------

          The fiscal year of the corporation shall be fixed by resolution of the
Board of Directors and may be changed by the Board of Directors.

     8.9  Seal.
          ----

          The corporation may adopt a corporate seal, which may be altered at
pleasure, and may use the same by causing it or a facsimile thereof, to be
impressed or affixed or in any other manner reproduced.

     8.10 Transfer Of Stock.
          -----------------

          Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignation or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate, and record the transaction in its books.

                                      -18-



     8.11  Stock Transfer Agreements.
           -------------------------

           The corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the corporation to restrict the transfer of shares of stock of the corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the General Corporation Law of Delaware.

     8.12  Registered Stockholders.
           -----------------------

           The corporation shall be entitled to recognize the exclusive right of
a person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

     8.13  Facsimile Signature
           -------------------

           In addition to the provisions for use of facsimile signatures
elsewhere specifically authorized in these Bylaws, facsimile signatures of any
officer or officers of the Corporation may be used whenever and as authorized by
the Board of Directors or a committee thereof.

                                   ARTICLE IX

                                   AMENDMENTS
                                   ----------

           The Bylaws of the corporation may be adopted, amended or repealed by
the stockholders entitled to vote; provided, however, that the corporation may,
in its certificate of incorporation, confer the power to adopt, amend or repeal
Bylaws upon the directors. The fact that such power has been so conferred upon
the directors shall not divest the stockholders of the power, nor limit their
power to adopt, amend or repeal Bylaws.

                                      -19-
