Incorporation.

     Section 2. Place of Business. In addition to its registered office, the

     Section 1. Annual Meetings. Annual meetings of the shareholders shall be
held at such times as shall be determined by the Board of Directors. At each
annual meeting, the shareholders shall elect a Board of Directors, and shall
transact such other business as may be properly brought before the meeting.

     Section 2. Special Meetings. Unless otherwise provided by the Articles of
Incorporation, special meetings of the shareholders may be called by the
President, the Board of Directors or the holders of shares representing not less
than [10%] of the votes entitled to be cast on any issue at meetings of

business transacted at a special meeting shall be confined to the purposes
stated in the notice of such meeting.

     Section 3. Place of Meetings. Meetings of the shareholders of the
Corporation shall be held at such places within or without the State of Texas as
shall be determined by the Board of Directors or, in the absence of such a

hour of the meeting and, in case of a special



meeting, the purpose or purposes for which the meeting is called, shall be
delivered not less than ten (10) nor more than sixty (60) days before the date
of the meeting, either personally or by mail, by or at the direction of the
President, the Secretary or the person calling the meeting, to each shareholder
entitled to vote at the meeting. If mailed, such notice shall be deemed to be
delivered when deposited in the United States mail addressed to the shareholder
at his or her address as it appears on the stock transfer books of the
Corporation, with postage thereon prepaid.

     Section 5. Voting List. At least ten (10) days before each meeting of the

the registered office or principal place of business of the Corporation for a
period of ten (10) days prior to such meeting, and shall be subject to
inspection by any shareholder who may be present. The original stock transfer

Failure to comply with the requirements of this Section shall not affect the
validity of any action taken at such meeting.

     Section 6. Quorum of Shareholders; Adjournment.

entitled to be cast at a meeting, present in person or represented by proxy,
shall be requisite to and shall constitute a quorum at all meetings of the
shareholders for the transaction of business except as otherwise provided by the
Articles of Incorporation or by these Bylaws. Once a quorum is present at a
meeting of shareholders, the shareholders represented in person or by proxy at
the meeting may conduct such business as may be properly brought before the
meeting until it is adjourned, and the subsequent withdrawal from the meeting of
any shareholder or the refusal of any shareholder represented in person or by
proxy to vote shall not affect the presence of a quorum at the meeting. Upon
attainment of representation by a quorum, subsequent to an adjournment of the
meeting, any business may be transacted which might have been transacted at the
meeting as originally notified.

          (B) If a quorum is not present or represented at any meeting of the
shareholders, the shareholders entitled to vote thereat, present in person or
represented by proxy, shall have the power to adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum is
present or represented. When a determination of shareholders entitled to vote at
any meeting of shareholders has been made as provided in these Bylaws, such
determination shall apply to any adjournment thereof except where the
determination has been made through the closing of the share transfer records
and the stated period of closing has expired.

such person as may be chosen by the holders of shares representing a majority of
the votes which could be cast by those present, in person or by proxy, and
entitled to vote shall call to order any meeting of the shareholders and act as
chairman of the meeting. The Secretary of the Corporation, if present, shall act
as secretary of the meeting, but in his absence, the secretary of the meeting
shall be such person as the chairman of the meeting appoints. The chairman of
any meeting of shareholders shall determine the order of business and the
procedure at the meeting, including regulation of the manner of voting and the
conduct of discussion; but the order of business to be followed at any meeting
at which a quorum is present may be changed by the holders of shares of stock
present in person or by proxy and entitled to vote at such meeting (determined
by a majority of the votes cast).

     Section 8. Required Vote. With respect to matters other than elections of
directors, except as otherwise required by statute, the Articles of

holders of shares entitled to vote in the election of directors.

     Section 9. Method of Voting; Proxies. Each outstanding share, regardless of
class, shall be entitled to one vote on each matter submitted to a vote at a
meeting of the shareholders, except to the extent that the voting rights of the
shares of any class or classes are enhanced or limited by statute, by the
Articles of Incorporation (including amendments thereto) or by agreement. At any
meeting of the shareholders, each shareholder having the right to vote shall be
entitled to vote in person, or by written proxy appointed by an instrument
executed by such shareholder. No proxy shall be valid after eleven (11) months
from the date of its execution, unless otherwise provided in the proxy. A proxy
shall be revocable unless expressly provided therein to be irrevocable and
unless otherwise made irrevocable by law. Each proxy shall be filed with the
Secretary of the Corporation prior to or at the time of the meeting. Any vote
may be taken by voice or by show of hands unless a shareholder entitled to vote
objects, in which case written ballots shall be used.

     Section 10. Action Without Meeting. Any action which must or may be taken
at any annual or special meeting of shareholders may be taken without a meeting,
without prior notice and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall be signed by (i) the holders of all the
shares entitled to vote with respect to the action that is the subject of the
consent, or (ii) if the Articles of Incorporation so provide, the holders of
shares of 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 on the

                                        3

action without a meeting by less than unanimous written consent shall be given

the express purpose of objecting to the transaction of any business on the
ground that the meeting is not lawfully called or convened.

Directors shall be determined from time to time by resolution of a majority of

the number of directors shall be at least one (1) and no decrease shall have the
effect of shortening the term of any incumbent director.

or at a special meeting of shareholders called for that purpose; provided that,
during the period between any two (2) successive annual meetings of
shareholders, the Board of Directors may not fill more than two (2) vacancies
resulting from an increase in the number of directors. A director elected to
fill a vacancy shall be elected for the unexpired term of his or her
predecessor, in office.

their meetings, both regular and special, either within or without the State of

be held without notice at such times and places as may be fixed from time to
time by resolutions adopted by the Board of Directors and communicated to all
directors at their last known addresses. Except as otherwise provided by

waiver of notice of such meeting.

     Section 11. Quorum; Majority Vote. At all meetings of the Board of
Directors, the presence of a majority of the number of directors fixed in
accordance with these Bylaws shall be necessary and sufficient to 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 required by
statute, the Articles of Incorporation or these Bylaws. If a quorum is not
present at any meeting of the directors, 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. Upon attainment of representation by a
quorum, subsequent to an adjournment of the meeting, any business

                                        5



may be transacted which might have been transacted at the meeting as originally
notified.

dissent shall not apply to a director who voted in favor of such action.

determine from time to time the amount of compensation, if any, which shall be
paid to its members for their services as directors and as members of standing
or special committees of the Board. The Board shall also have power in its
discretion to provide for and to pay to directors rendering services to the
Corporation not ordinarily rendered by directors as such, special compensation
appropriate to the value of such services as determined by the Board from time
to time. Nothing in these Bylaws shall be construed to preclude any directors
from serving the Corporation in any capacity other than as a director and
receiving compensation therefor.

     Section 14. Procedure. The Board of Directors shall keep regular minutes of
its proceedings. The minutes shall be placed in the minute book of the
Corporation.

taken, is signed by all the members of the Board of Directors or such committee,
as the case may be. Such consent shall have the same force and effect as
unanimous vote at a meeting, and may be stated as such in any document or
instrument filed with the Secretary of State. The signed consent or a copy
thereof shall be placed in the minute book of the Corporation.

     Section 16. Telephone Meeting. Members of the Board of Directors or of any

shall consist of money paid, labor done (including services actually performed
for the Corporation) or property (tangible or intangible) actually received.
Neither promissory notes nor the promise of future services shall constitute
payment for shares. In the absence of fraud in the transaction, the judgment of
the Board of Directors as to the value of consideration received shall be
conclusive. When consideration, fixed as provided by law, has been paid, the
shares shall be deemed to have been issued and shall be considered fully paid
and nonassessable.

     Section 4. Lost, Stolen or Destroyed Certificates. The Board of Directors,
the President, or such other officer or officers of the Corporation as the Board
of Directors may from time to time designate, in their discretion, may direct a
new certificate or certificates representing shares to be issued in place of any
certificate or certificates theretofore issued by the Corporation alleged to
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the person claiming the certificate or certificates to be lost, stolen
or destroyed. When authorizing such issuance of a new certificate or
certificates, the Board of Directors, the President, or any such other officer,
in their discretion and as a condition precedent to the issuance thereof, may
require the owner of such lost, stolen or destroyed certificate or certificates,
or his or her legal representative, to advertise the same in such manner as the
Board of Directors, the President or such other officer shall require and/or
give the Corporation a bond in such form, in such sum, and with such surety or
sureties, as they may direct as indemnity against any claim that may be made
against the Corporation with respect to the certificate or certificates alleged
to have been lost, stolen or destroyed.

     Section 5. Transfers of Shares. Shares of stock shall be transferable only
on the books of the Corporation at the direction of the registered holder
thereof or by such holder's duly authorized attorney. Upon surrender to the
Corporation or the transfer agent of the Corporation of a certificate or
certificates representing shares, duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, with all required
stock transfer tax stamps affixed thereto and cancelled or accompanied by
sufficient funds to pay such taxes, it shall be the duty of the Corporation or
the transfer agent of the Corporation to issue a new certificate or certificates
to the person entitled thereto, cancel the old certificate or certificates and
record the transaction upon its books.

     Section 6. Registered Shareholders. The Corporation shall be entitled to
treat the holder of record of any share or shares of stock as the holder in fact
thereof and, accordingly, shall not be bound to recognize any equitable or other
claim to or interest in

                                       12



such share or shares on the part of any other person, whether or not it shall
have express or other notice thereof, except as otherwise provided by law.

     Section 7. Restriction on Transfer of Shares of Stock. These Bylaws
authorize (but do not require) a restriction on the transfer of the
Corporation's shares which:

          (A) maintains the status of the Corporation as an electing small
business corporation under Subchapter S of the United States Internal Revenue
Code;

          (B) obligates the holders of the restricted stock to offer to the
other holders of stock of the Corporation a prior opportunity, to be exercised
within a reasonable time, to acquire the restricted stock pursuant to an
agreement respecting the purchase and sale of the restricted stock;

          (C) obligates the Corporation to the extent permitted by law or any
holder of stock of the Corporation to purchase the stock which is the subject of
an agreement respecting the purchase and sale of the restricted stock; or

          (D) requires the Corporation and the holders of any stock of the
Corporation to consent to any proposed transfer of the restricted stock for the
purpose of preventing violations of federal or state law.

     The Corporation will furnish to the holder of a certificate of stock in the
Corporation, without charge, upon written request to the Corporation at its
principal place of business or registered office, a copy of the Bylaws and the
Agreement, if any, restricting the transfer of stock.

                                  ARTICLE VIII.

                                  MISCELLANEOUS

     Section 1. Fixing Record Dates. For the purpose of determining shareholders
entitled to notice of or to vote at any meeting of shareholders or any
adjournment thereof, or entitled to receive a distribution by the Corporation
(other than a distribution involving a purchase or redemption by the Corporation
of any of its shares) or a share dividend, or in order to make a determination
of shareholders for any other proper purpose (other than determining
shareholders entitled to consent to action by shareholders proposed to be taken
without a meeting of shareholders), the Board of Directors may (i) fix in
advance the record date for any such determination of shareholders, though such
record date shall not be more than sixty (60) days and, for the purpose of
determining shareholders entitled to notice of or to vote at a meeting of
shareholders, shall not be less than ten (10) days, prior to the date on which
the particular action requiring such determination of shareholders is to be
taken, or (ii) close the

                                       13



share transfer records for a period of not more than sixty (60) days and, for
the purpose of determining shareholders entitled to notice of or to vote at a
meeting of shareholders, for a period of not less than ten (10) days, prior to
the date on which the particular action requiring such determination of
shareholders is to be taken. In the absence of any such action by the Board of
Directors, the date on which notice of the meeting is mailed or the date on
which the resolution of the Board of Directors declaring such distribution or
share dividend is adopted, as the case may be, shall be the record date for such
determination of shareholders. The record date for the purpose of determining
shareholders entitled to consent to an action shall be fixed in accordance with
applicable statutes.

     Section 2. Reserves. There may be created from time to time by resolution
of the Board of Directors, out of the earned surplus of the Corporation, such
reserve or reserves as the directors from time to time, in their discretion,
think proper to provide for contingencies, or to equalize dividends, or to
repair or maintain any property of the Corporation or for such other purpose as
the directors shall think beneficial to the Corporation. The directors may
modify or abolish any such reserve in the manner in which it was created.

     Section 3. Signature of Negotiable Instruments. All bills, notes, checks or
other instruments for the payment of money shall be signed or countersigned by
such officer, officers, agent or agents and in such manner as are permitted by
these Bylaws and/or as, from time to time, may be prescribed by resolution
(whether general or special) of the Board of Directors.

     Section 4. Fiscal Year. The business of the Corporation shall be conducted
on either a fiscal year or calendar year basis, and the selection of the basis
to be used shall be, and is hereby delegated to the discretion of the Board of
Directors.

     Section 5. Seal. The Corporation's seal, if obtained, shall be in such form
as shall be adopted and approved from time to time by the Board of Directors.
The seal may be used by causing it, or a facsimile thereof, to be impressed,
affixed, imprinted or in any manner reproduced. Except as expressly required by
law, no action shall be invalid or unenforceable for failure to use the
corporate seal in connection therewith.

     Section 6. Books and Records. The Corporation shall keep correct and
complete books and records of account and shall keep minutes of the proceedings
of its shareholders and Board of Directors and shall keep at its registered
office or principal place of business, or at the office of its transfer agent or
registrar, a record of its shareholders, giving the names and addresses of all
shareholders and the number and class of the shares held by each.

     Section 7. Resignation. Unless otherwise expressly provided, any director,
committee member, officer or agent may

                                       14



resign by giving written notice to the President or the Secretary. The
resignation shall take effect at the time specified therein, or immediately if
no time is specified. Unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

     Section 8. Surety Bonds. Such officers and agents of the Corporation (if
any) as the President, or the Board of Directors may direct, from time to time,
shall be bonded for the faithful performance of their duties and for the
restoration to the Corporation, in case of their death, resignation, retirement,
disqualification or removal from office, of all books, papers, vouchers, money
and other property of whatever kind in their possession or under their control
belonging to the Corporation, in such amounts and by such surety companies as
the President or the Board of Directors may determine. The premiums on such
bonds shall be paid by the Corporation, and the bonds so furnished shall be in
the custody of the Secretary.

     Section 9. Interested Directors, Officers and Security Holders. No contract
or transaction between the Corporation and one or more of its directors,
officers or security holders, or between the Corporation and any other
corporation, partnership, association, trust, plan or other organization or
enterprise in which one or more of the Corporation's directors, officers or
security holders are directors, officers, security holders, members or
employees, or have a direct or indirect financial interest, shall be void or
voidable solely because of such position or interest, solely because the
director, officer or security holder is present at or participates in the
meeting of the Board of Directors or committee thereof which authorizes the
contract or transaction, or solely because the votes of such director, officer
or security holder are counted for such purpose, if:

          (a) the material facts of the contract or transaction and of the
relationship or interest are known or disclosed to the Board of Directors or the
committee, and the Board or committee in good faith authorizes the contract or
transaction by the affirmative vote of a majority of the disinterested
directors, even though the disinterested directors be less than a quorum;

          (b) the material facts of the contract or transaction and of the
relationship or interest are known or disclosed to the shareholders entitled to
vote thereon, and the contract or transaction is specifically approved in good
faith by a vote of the shareholders; or

          (c) the contract or transaction is fair to the Corporation as of the
time it is authorized, approved, or ratified by the Board of Directors, a
committee thereof, or the shareholders.

     Common or interested directors may be counted in determining the presence
of a quorum at a meeting of the Board of Directors or of a committee which
authorizes the contract or

                                       15



transaction. No director shall be liable to account to the Corporation for any
profits realized by, from or through any such contract or transaction by reason
of an interest therein when such contract or transaction has been authorized or
ratified in accordance with the foregoing. This section shall not be construed
to invalidate any contract or transaction which would otherwise be valid in the
absence of this provision.

     Section 10. Indemnification. Any person who was, is, or is threatened to be
made, a named defendant or respondent in any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, arbitrative, investigative
or administrative, any appeal in such action suit or proceeding, and any inquiry
or investigation that could lead to such an action, suit or proceeding
(collectively, a "proceeding"), by reason of the fact that he or she is or was a
director or officer [employee or agent] of the Corporation, or, while a director
or officer of the Corporation, is or was serving at the request of the
Corporation as a director, officer, partner, venturer, proprietor, trustee,
employee, agent, or similar functionary of another foreign or domestic
corporation, partnership, joint venture, sole proprietorship, trust, employee
benefit plan, or other enterprise, shall be indemnified by the Corporation to
the fullest extent authorized by the Texas Business Corporation Act, as the same
exists or may hereafter be amended (but in the case of any such amendment, only
to the extent that such amendment permits the Corporation to provide broader
indemnification rights than such law permitted the Corporation to provide prior
to such amendment), against all expense, liability and loss (including
attorneys' fees, judgments, court costs, fines, penalties, excise taxes, and
amounts paid in settlement) reasonably incurred or suffered in connection
therewith and such indemnification shall continue as to any such person who has
ceased to be a director or officer [employee or agent] and shall inure to the
benefit of such persons' heirs, executors and administrators. The right to
indemnification conferred in this Section shall be a contract right and shall
include the right to be paid by the Corporation the expenses (court costs and
attorneys' fees) incurred in defending any such proceeding in advance of its
final disposition; provided, the applicable requirements of the Texas Business
Corporation Act are met prior to such advancement.

     The right to indemnification and to the advancement of expenses conferred
in this Section shall not be exclusive of, nor shall it be construed to limit,
any other right which any person may have or hereafter acquire under any
statute, the Articles of Incorporation, these Bylaws, agreement, vote of
shareholders or otherwise.

                                   ARTICLE IX.

                                   AMENDMENTS

     These Bylaws may be altered, amended or repealed or new Bylaws may be
adopted at any meeting of the Board of Directors at which a

                                       16



quorum is present by the affirmative vote of a majority of the directors present
at such meeting.
