registered office and shall have a registered agent whose business office is
identical with such registered office.

      Section 1.2 Other Offices. The corporation may have offices at such place

      Section 2.1 Issuance and Notice. Certificates of stock shall be numbered
consecutively in the order in which they are issued. They shall be signed by the
President and Secretary and the seal of the corporation shall be affixed
thereto. In an appropriate place in the corporate records there shall be entered
the name of the person owning the shares, the number of shares and the date of

corporation may appoint a transfer agent or agents and a registrar or registrars
of transfer (other than the corporation itself or an employee thereof) for the
issuance of shares of stock of the corporation and may require that all stock
certificates bear the signature of such transfer agent or registrar. In the
event such a transfer agent or registrar is thus appointed, any share
certificate may be signed by the facsimile of the signature of either or both of
the President and Secretary printed thereon. If the same is countersigned by the
transfer agent of the corporation, the certificates bearing the facsimile of the
signatures of the President and Secretary shall be valid in all respects as if
such person or persons were still in office even though such person or persons
shall have died or otherwise ceased to be officers.

      Section 2.3 Transfer. Upon the surrender to the corporation or to the
transfer agent of the corporation of a certificate for shares duly endorsed or

thereto, to cancel the surrendered certificate and to record the transaction
upon its books.

      Section 2.4 Lost Certificates. The Board of Directors may direct a new
certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the corporation that is alleged to have been
lost or destroyed. 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 or destroyed
certificate or certificates, or his legal representative, to (i) advertise the
same in such manner as it shall require, and/or (ii) give the corporation a bond
in such sum as it may direct as indemnity against any


                                      -2-


claim that may be made against the corporation with respect to the certificate
alleged to have been lost or destroyed.

      Section 2.5 Voting. The holders of the common stock shall be entitled to

      Section 3.1 Place of Meetings. All meetings of the Shareholders shall be
held at the registered office of the corporation or at such other place, either
within or without the State of Texas, as the Board of Directors or the
Shareholders may, from time to time, elect.

      Section 3.2 Annual Meeting. An annual meeting of the common stock
Shareholders shall be held each year at 11:00 a.m. on the last Monday of the
last month in the fiscal year of the corporation. If such date is a legal
holiday, then the meeting shall be held at 11:00 a.m. on the next regular
business day following the legal holiday or at such other date and time as shall
be designated, from time to time, by the Board of Directors and stated in the
notice of the meeting. If an annual meeting has not been called and held within
six months after the time designated, any common stock Shareholder may call such
meeting.

      Section 3.3 Special Meetings. Special meetings of the common stock
Shareholders may be called at any time by (i) the President, (ii) a majority of

holder or holders of one-third or more of the capital stock of the corporation
outstanding and entitled to vote.

      Section 3.4 Notice of Meeting. Written notice stating the place, day and
hour of the meeting, and, in the case of a special meeting, the purpose or
purposes for which the meeting is called, shall be given not less than ten nor
more than fifty days before the date of the meeting, either by hand or by
first-class mail, to each Shareholder of record entitled to vote at such
meeting. If mailed, such notice shall be deemed to be delivered when deposited
in the United States mail with first-class postage thereon, prepaid and
addressed to the Shareholder at his address as it appears on the stock transfer
books of the corporation.

      Section 3.5 Waiver of Notice. Notice of a meeting need not be given to any
Shareholder who signs a waiver of notice, in person or by proxy, either before
or after the meeting; and a Shareholder's waiver shall be deemed the equivalent
of giving proper notice. Attendant of a Shareholder at a meeting, either in
person or by proxy, shall by itself constitute a waiver of notice and a waiver
of any and all objections to the time or place of the meeting or the manner in
which it has been called or convened, unless a Shareholder attends a meeting
solely for the purpose of stating, at the beginning of the meeting, any such
objection or objections to the transaction of business. Unless otherwise
specified herein, neither the business transacted nor the purpose of the meeting
need be specified in the waiver.

      Section 3.6 Quorum. The majority of the shares entitled to vote,
represented in person or by proxy, shall constitute a quorum at any meeting of
Shareholders. If a quorum is present, the affirmative vote of the majority of
shares represented at the meeting and entitled to vote on the subject matter
shall be the act of the Shareholders. When a quorum is once present to


                                      -4-


organize a meeting, the Shareholders present may continue to do business at the
meeting until adjournment even though enough Shareholders withdraw to leave less
than a quorum.

      Section 3.7 Adjournment. Any meeting of the Shareholders may be adjourned
by the holders of a majority of the voting shares represented at a meeting,
whether or not a quorum is present. Notice of the adjourned meeting or of the
business to be transacted at such meeting shall not be necessary, provided the
time and place to which the meeting is adjourned are announced at the meeting at
which the adjournment is taken. At an adjourned meeting at which a quorum is
present or represented, any business may be transacted which could have been
transacted at the meeting originally called.

      Section 3.8 Voting Rights. Each Shareholder shall be entitled at each
Shareholders' meeting to one vote for each share of the capital stock having
voting power held by such Shareholder.

      Section 3.9 Proxies. A Shareholder entitled to vote may vote in person or
by proxy executed in writing by the Shareholder or by his attorney-in-fact. A
proxy shall not be valid after eleven months from the date of its execution
unless a longer period is expressly stated in such proxy.

      Section 3.10 Action by Consent of Shareholders. Any action required or
permitted to be taken at a meeting of the Shareholders may be taken without a
meeting if a written consent setting forth the action shall be signed by all of
the Shareholders entitled to vote with respect to the subject matter thereof.
Any such consent shall be filed with the Secretary of the corporation and shall
have the same force and effect as a unanimous vote of the Shareholders.

agreement between the Shareholders, the full and entire management of the
affairs and business of the corporation shall be vested in the Board of
Directors which shall have and which may exercise all of the powers that may be
exercised or performed by the corporation.

      Section 4.2 Number, Qualification and Term of Office. The business and
affairs of the corporation shall be managed by a Board of Directors which shall
consist of not less than three (3) nor more than nine (9) members unless the
number of Shareholders shall be less than three (3). In the event there shall be
less than three (3) Shareholders, the minimum number of the Board of Directors
may equal the number of Shareholders. Each member of the Board of Directors of
the corporation shall be elected by the affirmative vote of a majority of the
voting shares represented at the meeting at which such election is held. None of
the Directors need be a resident of the State of Texas or hold shares of stock
in the corporation. The Directors shall be elected at an annual meeting of the
Shareholders and shall serve for a term of one (1) year or until their
successors are elected and qualified.

      Section 4.3 Vacancies. The Directors may fill the place of any Director
which may become vacant prior to the expiration of his term, such appointment by
the Directors to continue until the expiration of the term of the Director whose
place has become vacant.

may receive a fixed sum salary and reimbursement of expenses of attendance at
each meeting of the Board in


                                      -6-


accordance with directions from the Shareholders at a duly constituted meeting
of the Shareholders. A Director may serve the corporation in a capacity other

other capacity.

charges prepaid, to the address of each Director.

      Section 5.5 Waiver of Notice. A Director may waive in writing notice of a

shall be deemed the


                                      -7-


equivalent of giving notice. Attendance of a Director at a meeting shall
constitute a waiver of notice of that meeting unless he attends for the express
purpose of objecting to the transaction of business on the grounds that the
meeting has not been lawfully called or convened.

      Section 5.6 Quorum. At meetings of the Board of Directors, a majority of
the Directors shall constitute a quorum for the transaction of business or in
the event that the minimum number of Directors shall be less than three (3),

quorum. If a quorum is present, the acts of a majority of Directors in
attendance shall be the acts of the Board.

      Section 5.7 Adjournment. A meeting of the Board of Directors may be
adjourned. Notice of the time and the place of the adjourned meeting and of the
business to be transacted thereat, other than by announcement at the meeting at
which the adjournment is taken, shall not be necessary. At an adjourned meeting
at which a quorum is present, any business may be transacted which could have
been transacted at the meeting originally called.

      Section 5.8 Action by Consent. If all the Directors, severally or
collectively, consent in writing to any action taken or to be taken by the
corporation and the writing or writings evidencing their consent are filed with
the Secretary of the corporation, the action shall be as valid as though it had
been authorized at a meeting of the Board of Directors.

paid or allowed to or in respect of (i) all officers and any or all employees of

the corporation and (ii) the Directors of the corporation, as such. Directors of
the corporation shall not be disqualified from voting on their own or any other
person's plan, benefit or compensation to be paid by the corporation merely
because they or such other person is a Director or an officer or an employee of
the corporation. The Board of Directors may delegate these functions to any

Director.

                                 INDEMNIFICATION

   Section 9.1 Circumstances for Claim of Indemnification. Any person who was
or is a party to, 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 the


                                      -11-


corporation) by reason of the fact that he or she is or was a director, officer,
employee or agent of this corporation, shall be indemnified by this corporation,
against all expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by him or her in connection
with such action, suit or proceeding if he or she acted in a manner reasonably
believed by such person to be in or not opposed to the best interests of this
corporation and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that his 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 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 conduct was unlawful.

      Section 9.2 Determination of Right to Indemnification. Determination of
the right to indemnification and the amount thereof may be made, at the option
of the person to be indemnified, pursuant to procedure set forth from time to
time in the by-laws or by any of the following procedures: (i) order of the
court or administrative body or agency having jurisdiction of the action, suit
or proceeding, (ii) resolution adopted by a majority of a quorum of the Board of
Directors of the corporation without counting in such majority or quorum any
Directors who have incurred expenses in connection with such action, suit or
proceeding, (iii) resolution adopted by a majority of a quorum of the
Shareholders entitled to vote at any meeting, or (iv) order of any court having
jurisdiction over the corporation. Any such determination that a payment by way
of indemnity should be made shall be binding upon the corporation. Such right


                                      -12-


of indemnification shall not be exclusive of any other right which such
Directors, officers and employees of the corporation and the other persons above
mentioned may have or hereafter acquire and, without limiting the generality of
such statement, they shall be entitled to their respective rights of
indemnification or reimbursement under any by-laws, agreement or vote of the
Shareholders, their rights under this Article being cumulative. The provisions
of this Article shall apply to any member of any committee appointed by the
Board of Directors as fully as though such person had been a Director, officer
or employee of the corporation.

      Section 9.3 Payment During Pendency of Action. A disinterested majority of
the Board of Directors of this corporation or a majority of a quorum of the
Shareholders entitled to vote at a meeting shall be authorized to pay to any
person entitled to indemnification under this Article all actual expenses
incurred in connection with such action, suit or proceeding during the pendency
thereof.

      Section 9.4 Intent. It is the intention of this corporation that this
Article of the by-laws of this corporation and the indemnification hereunder
shall extend to the maximum indemnification possible under the laws of the State
of Texas and if one or more words, phrases, clauses, sentences or sections of
this Article should be held unenforceable for any reason, all of the remaining
portions of this Article shall remain in full force and effect.

                                    ARTICLE X

                                    DEALINGS

      Section 10.1 Related Transactions. No contract or other transaction
between this corporation and any other firm, association or corporation shall be
affected or invalidated by the


                                      -13-


fact that any of the members of the Board of Directors of this corporation are
interested in or are members, shareholders, governors or directors of such firm,
association or corporation; and no contract, act or transaction of this
corporation with any individual, firm, association or corporation shall be
affected or invalidated by the fact that any of the members of the Board of
Directors of this corporation are parties to or interested in such contract, act
or transaction or are in any way connected with such individual, firm,
association or corporation. Each and every individual who may become a member of
the Board of Directors of this corporation is hereby relieved from any liability
that might otherwise exist from contracting with this corporation for the
benefit of himself or herself or any firm, association or corporation in which
he or she may in any way be interested. Notwithstanding the above, the
provisions of this Section 10.1 shall be applicable only in the absence of fraud
and only where the interest in such transaction of an interested party has been
disclosed and the interested party, if a Director, has abstained from a vote
thereon.

                                   ARTICLE XI

                             DIVIDENDS AND RESERVES

      Section 11.1 Dividends. The Board of Directors of the corporation may from
time to time declare, and in such event the corporation shall pay, dividends on
the corporation's outstanding shares in cash, property, or the corporation's own
shares, except when the corporation is insolvent or when the declaration or
payment thereof would be contrary to any restrictions contained in the Articles
of Incorporation and subject to the following provisions: dividends may be
declared and paid in cash or property only out of the unreserved and


                                      -14-


unrestricted earned surplus of the corporation or out of the unreserved and
unrestricted net earnings of the current fiscal year or the next preceding
fiscal year.

      Section 11.2 Reserves. Before payment of any dividend, there may be set
aside out of any funds of the corporation available for dividends such sum or
sums as the Directors, from time to time, in their absolute discretion, think
proper as a reserve fund to meet contingencies or for equalizing dividends or
for repairing or maintaining any property of the corporation or 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
manner by which it was created.

                                 ARTICLE XII

                                REIMBURSEMENT

      Section 12.1 Disallowed Corporate Deductions. Any payments made to an
officer of the corporation such as a salary, commission, bonus, interest, rent
or entertainment expense incurred by him, which shall be disallowed in whole or
in part as a deductible expense by the Internal Revenue Service, shall be
reimbursed by such officer to the corporation to the full extent of such
disallowance. It shall be the duty of the Directors, as a Board, to enforce
payment of each such amount disallowed. In lieu of payment by the officer,
subject to the determination of the Directors, proportionate amounts may be
withheld from his future compensation payments until the amount owed to the
corporation has been recovered.

      I, Michael J. Gross, Secretary of JTM Industries, Inc. formed and existing
under the laws of the State of Texas, do hereby certify that the foregoing is a
