remaining director, and the directors so chosen shall hold office until the next
annual election and until their successors are duly elected and shall qualify,
unless sooner displaced. If there are no directors in office, then an election

Directors shall be held at such time and place as shall be fixed by the vote of
the stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present. In the event of the failure of the
stockholders to fix the time or place of such first meeting of the newly elected
Board of Directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, the meeting may be held at such time and
place as shall be specified in a notice given as hereinafter provided for
special meetings of the Board of Directors, or as shall be specified in a
written waiver signed by all of the directors.

on the written request of two directors unless the board consists of only one
director, in which case special meetings shall be called by the president or
secretary in like manner and on like notice on the written request of the sole
director.

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 shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

               Section 9. Unless otherwise restricted by the certificate of
incorporation of these bylaws, any action required or permitted to be taken at

               In the absence of disqualification of a member of a committee,
the member or members thereof present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member.

               Any such committee, to the extent provided in the resolution of
the Board of Directors, shall have and may exercise all the powers and authority
of the Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the certificate of incorporation, adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the bylaws of the corporation; and,
unless the resolution or the certificate of incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to

if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

                                   FISCAL YEAR

               Section 4. The fiscal year of the corporation shall be fixed by

                                 INDEMNIFICATION

               Section 6. The corporation shall, to the fullest extent
authorized under the laws of the State of Delaware, as those laws may be amended
and supplemented from time to time, indemnify any director made, or threatened
to be made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation or, at the corporation's request, a
director or officer of another corporation, provided, however, that the
corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the corporation. The indemnification provided for in this Section 6
shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under any bylaw, agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in their official
capacities and as to action in another capacity while holding such office, (ii)
continue as to a person who has ceased to be a director, and (iii) inure to the
benefit of the heirs, executors and administrators of such a person. The
corporation's obligation to provide


                                       19
   20

indemnification under this Section 6 shall be offset to the extent of any other
source of indemnification or any otherwise applicable insurance coverage under a
policy maintained by the corporation or any other person.

               Expenses incurred by a director of the corporation in defending a
civil or criminal action, suit or proceeding by reason of the fact that he is or
was a director of the corporation (or was serving at the corporation's request
as a director or officer of another corporation) 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 to
repay such amount if it shall ultimately be determined that he is not entitled
to be indemnified by the corporation as authorized by relevant sections of the
General Corporation Law of Delaware. Notwithstanding the foregoing, the
corporation shall not be required to advance such expenses to an agent who is a
party to an action, suit or proceeding brought by the corporation and approved
by a majority of the Board of Directors of the corporation which alleges willful
misappropriation of corporate assets by such agent, disclosure of confidential
information in violation of such agent's fiduciary or contractual obligations to
the corporation or any other willful and deliberate breach in bad faith of such
agent's duty to the corporation or its shareholders.

               The foregoing provisions of this Section 6 shall be deemed to be
a contract between the corporation and each director who serves in such capacity
at any time while this bylaw is in effect, and any repeal or modification
thereof shall not affect any rights or obligations then existing with respect to
any state of facts then or theretofore existing or any action, suit or
proceeding theretofore or thereafter brought based in whole or in part upon any
such state of facts.


                                       20
   21

               The Board of Directors in its discretion shall have power on
behalf of the corporation to indemnify any person, other than a director, made a
party to any action, suit or proceeding by reason of the fact that he, his
testator or intestate, is or was an officer or employee of the corporation.

               To assure indemnification under this Section 6 of all directors,
officers and employees who are determined by the corporation or otherwise to be
or to have been "fiduciaries" of any employee benefit plan of the corporation
which may exist from time to time, Section 145 of the General Corporation Law of
Delaware shall, for the purposes of this Section 6, be interpreted as follows:
an "other enterprise" shall be deemed to include such an employee benefit plan,
including without limitation, any plan of the corporation which is governed by
the Act of Congress entitled "Employee Retirement Income Security Act of 1974,"
as amended from time to time; the corporation shall be deemed to have requested
a person to serve an employee benefit plan where the performance by such person
of his duties to the corporation also imposes duties on, or otherwise involves
services by, such person to the plan or participants or beneficiaries of the
plan; excise taxes assessed on a person with respect to an employee benefit plan
pursuant to such Act of Congress shall be deemed "fines."

                                  ARTICLE VIII

                             RIGHT OF FIRST REFUSAL

               Section 1. No stockholder shall sell, assign, pledge, or in any
manner transfer any of the shares of stock of the corporation or any right or
interest therein, whether voluntarily or by operation of law, or by gift or
otherwise, except by a transfer which meets the requirements hereinafter set
forth in this Bylaw:


                                       21
   22

               (a) If the stockholder desires to sell or otherwise transfer any
of his or her shares of stock, then the stockholder shall first give written
notice thereof to the corporation. The notice shall name the proposed transferee
and state the number of shares to be transferred, the proposed consideration and
all other terms and conditions of the proposed transfer.

               (b) For thirty (30) days following receipt of such notice, the
corporation shall have the option to purchase all, but not less than all, of the
shares specified in the notice at the price and upon the terms set forth in such
notice. In the event of a gift, property settlement or other transfer in which
the proposed transferee is not paying the full price for the shares, the price
shall be deemed to be the fair market value of the stock at such time as
determined in good faith by the Board of Directors. In the event the corporation
elects to purchase such shares, is shall give written notice to the transferring
stockholder of its election and settlement for said shares shall be made as
provided below in paragraph (d).

               (c) The corporation may assign its rights hereunder.

               (d) In the event the corporation and/or its assignee(s) elect to
acquire the shares of the transferring stockholder as specified in said
transferring stockholder's notice, the Secretary of the corporation shall so
notify the transferring stockholder and settlement thereof shall be made in cash
within thirty (30) days after the Secretary of the corporation receives said
transferring stockholder's notice; provided that if the terms of payment set
forth in said transferring stockholder's notice be payable in property other
than cash or evidences of indebtedness, the corporation shall have the right to
pay the purchase price in the form of cash equal to the value of such property.



                                       22
   23

               (e) In the event the corporation and/or its assignees(s) do not
elect to acquire the shares specified in the transferring stockholder's notice,
said transferring stockholder may, within the sixty-day period following the
expiration of the option rights granted to the corporation and/or its
assignees(s) herein, transfer the shares as specified in said transferring
stockholder's notice. All shares so sold by said transferring stockholder shall
continue to be subject to the provision of this Bylaw in the same manner as
before said transfer.


               (f) Anything to the contrary contained herein notwithstanding,
the following transactions shall be exempt from the provision of this Bylaw:



                  (1) A stockholder's transfer of any or all shares held either
during such stockholder's lifetime or on death by will or intestacy to such
stockholder's immediate family or to any custodian or trustee for the account of
such stockholder or such stockholder's immediate family. "Immediate family" as
used herein shall mean spouse, lineal descendant, father, mother, brother, or
sister of the stockholder making such transfer.

                  (2) A stockholder's transfer of any or all of such
stockholder's shares to a person who, at the time of such transfer, is a
stockholder of the corporation.

                  (3) A stockholder's transfer of any or all of such
stockholder's shares to a person who, at the time of such transfer, is an
officer or Director of the corporation.

                  (4) A corporate stockholder's transfer of any or all of its
shares pursuant to and in accordance with the terms of any merger,
consolidation,


                                       23
   24

reclassification of shares or capital reorganization of the corporate
stockholder, or pursuant to a sale of all or substantially all of the stock or
assets of a corporate stockholder.

                  (5) A transfer by a stockholder which is a limited or general
partnership to any or all of its partners or former partners.

                  (6) A corporate stockholder's transfer of any or all of its
shares to its stockholders on a pro rata basis.

               In any such case, the transferee, assignee, or other recipient
shall receive and hold such stock subject to the provisions of this Bylaw, and
there shall be no further transfer of such stock except in accord with this
Bylaw.

               (g) The provisions of this Bylaw may be waived with respect to
any transfer either by the corporation, upon duly authorized action of its Board
of Directors, or by the stockholders, upon the express written consent of the
owners of a majority of the voting power of the corporation (excluding the votes
represented by those shares to be transferred by the transferring stockholder).
This Bylaw may be amended or repealed either by a duly authorized action of the
Board of Directors or by the stockholders, upon the express written consent of
the owners of a majority of the voting power of the corporation.

               (h) Any sale or transfer, or purported sale or transfer, of
securities of the corporation shall be null and void unless the terms,
conditions, and provisions of this Bylaw are strictly observed and followed.

               (i) The foregoing right of first refusal shall terminate on
either of the following dates, whichever shall first occur:

                  (1) On May 24, 2005; or



                                       24
   25

                  (2) Upon the date securities of the corporation are first
offered to the public pursuant to a registration statement filed with, and
declared effective by, the United States Securities and Exchange Commission
under the Securities Act of 1933, as amended.

               (j) The certificates representing shares of stock of the
corporation shall bear on their face the following legend so long as the
foregoing right of first refusal remains in effect:

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT
               OF FIRST REFUSAL OPTION IN FAVOR OF THE CORPORATION AND/OR ITS
               ASSIGNEE(S), AS PROVIDED IN THE BYLAWS OF THE CORPORATION.

                                   ARTICLE IX

                                   AMENDMENTS

               Section 1. These bylaws may be altered, amended or repealed or
new bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by 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
bylaws be contained in the notice of such special meeting. If the power to
adopt, amend or repeal bylaws is conferred upon the Board of Directors by the
certificate or incorporation it shall not divest or limit the power of the
stockholders to adopt, amend or repeal bylaws.
