and interests hereinafter in this Indenture described and set forth in Article II hereof, captioned “Trust Estate”. Grantors are of the opinion that, because of the essential nature of such property, property rights and interests and the
division of same in some instances into undivided fractional interests in contractual rights and benefits, the best method for each of them to realize upon and liquidate his interests in said property, property rights and interests is to transfer
the same to the Trustee, to be conserved and liquidated in accordance with the terms of this Indenture. Accordingly each Grantor has by an assignment and conveyance of even date herewith assigned and conveyed to the Trustee all his right, title and
interest in and to said property and property rights. A copy of said Assignment and Conveyance (exclusive of signatures and acknowledgments) is attached hereto as Exhibit A hereof and reference is made thereto for all the purposes hereof.

Trustee, it is agreed by and between each of the Grantors and the Trustee as follows:

any business pursuant hereto, but the operations of the Trustee hereunder shall be restricted to holding the property, property rights and interests assigned and conveyed to it hereunder and receiving and holding such other property, property rights
and interests that may accrue to it hereunder, and no part of the trust estate or the income therefrom shall be used by the Trustee for any purpose other than for the payment of expenses in connection with the administration of the trust estate as
herein specifically provided for and the distribution of the net income to the Certificate holders. 
 ARTICLE IV. 

TITLE AND THE FUNCTION OF THE TRUSTEE 

The Trustee shall take and hold title to the trust estate, IN TRUST, HOWEVER, to be administered and disposed of by it in accordance with the
terms of this Indenture for the benefit of all the Certificate holders in proportion to the respective interests of such holders as represented by said Certificates. It shall collect and receive all income, monies and proceeds accruing to the trust
estate and give receipts and acquittances therefor. The Trustee shall have the power to execute and deliver all instruments and do and perform all acts in its opinion necessary or appropriate to conserve, uphold, defend and evidence the trust
estate, its title thereto and its right to income accruing thereto, and in connection with such conservation, upholding, defending and evidencing, and for no other purpose, it shall have all necessary powers, which, by way of example, shall include
the power to institute, contest, defend, arbitrate, compromise, waive, release or abandon any action, proceeding, claim, demand or right. The Trustee or any Certificate holder may, but shall not be obligated to, at any time and from time to time, in
its or his discretion, make advances to satisfy or meet obligations of the trust estate; but all monies so advanced by the Trustee or any Certificate holder, together with interest at the rate of 6% per annum thereon, shall be repaid out of the
first available funds coming into the possession of the Trustee and belonging to the trust estate. Until such repayment the Trustee or Certificate holder shall have a lien upon the trust estate for such advances together with interest thereon prior
to the interest of any other Certificate holders. 
 The Trustee may from time to time and shall, at least once every three years from the
date hereof, provided that the income accruing to the Trustee is sufficient to defray the costs thereof, conduct an investigation to determine whether the Trustee is receiving all of the monies, income, gains and revenues


  
 Page 6 













 
properly accruing to the trust estate. In addition, Trustee shall undertake such an investigation at any time when specifically directed in writing so to do by Certificate holders owning more
than 10% of the outstanding units of interest. In conducting this investigation, the Trustee may employ and designate such independent agents as it shall deem qualified to conduct such an investigation and as in its discretion it may deem necessary,
and the Trustee may rely in good faith upon the opinions, reports, recommendations and conclusions of such persons, and the Trustee shall not have any liability to any Certificate holder or former Certificate holder for any action taken, omitted or
suffered in good faith in reliance upon the opinions, reports, recommendations and conclusions received from such persons. 
 The Trustee in
the performance of its duties hereunder shall not have the power or authority (a) to engage in any trade or business, (b) to invest or reinvest any moneys or properties forming a part of the trust estate, or to use any of such moneys for
any purpose other than the purposes authorized herein, or (c) to sell any part of the trust estate, or to dispose of any part of the trust estate other than by transfers and distributions made in connection with the termination of all or any
part of this Trust in accordance with the provisions of Article X hereof. 
 No person paying money to the Trustee shall be bound to see to
the application thereof. 
 The Trustee, individually or in any representative or fiduciary capacity other than as Trustee under this
Indenture, may acquire, own and dispose of Certificates to the same extent as if it were not Trustee hereunder. 
 The Trustee shall at any
time and from time to time, upon the request in writing of (i) any Certificate holder, or (ii) any holder of a Warrant to purchase units of interest, issued under a Warrant Agreement dated as of October 1, 1956, between certain of the

Act of 1933 and file said Registration Statements with the Securities and Exchange Commission, Washington, D.C., and prepare, execute and deliver each and every instrument and do and perform each and every act deemed necessary or appropriate by the
Trustee or required by law to cause said Registration Statements and any amendments thereto to become effective, including expressly any and all post-effective amendments of any Registration Statement required by any undertaking therein or requested
by any such Certificate holder or Warrant holder. The Trustee shall at any time and from time to time upon like request execute and deliver each and every instrument and do and perform each and every act deemed necessary or appropriate by the
Trustee or required by law to qualify the Warrants referred to above and/or any units of interest for sale in any state of the United States pursuant to the laws thereof. 

In no event shall the Trustee be obligated to sign or file any Registration Statement which is not acceptable to it in form and content or to
take any action under the preceding paragraph which in its opinion may subject it to any cost or expense unless, in the opinion of the Trustee, sufficient funds have been provided it, over and above and in addition to any funds or property in the
trust estate, to meet the costs and expenses of registration of the Warrants and units of interest and the preparation and delivery of Prospectuses or supplements thereto, or it has received an indemnity, commitment or undertaking satisfactory to it
with respect to the payment in full of said costs and expenses. 
 In no event shall the Trustee be obligated to take any action with
respect to the signing or filing of Registration Statements or amendments thereof or the filing of any document under the securities laws of any state unless the unit holders and/or Warrant holders requesting the signing and filing of said
Registration Statements, amendment or document, jointly and severally, agree in writing to indemnify and hold harmless the trust estate, the Trustee, in its capacity as Trustee and as a national banking institution, and any person who controls it,
from and against any loss, expense, liability or claim which arises out of or 

  
 Page 7 













 
is based upon any alleged untrue statement of a material fact in such Registration Statement, amendment or other document or in any Prospectus (or supplement or amendment thereof) whether
preliminary, amended, supplemented or otherwise included therein, or arises out of or is based upon any alleged omission to state a material fact required to be stated therein or necessary to make the statements made therein not misleading; such
indemnification and undertaking to include the obligation to bear all expenses of defending any action in respect of which indemnity may be sought by the Trustee, including fees of counsel of the Trustee. 

In connection with the filing of said Registration Statements, amendments or other documents, the Trustee shall make available to the persons
requesting the filing of the same and to the Depositary under the Warrant Agreement as many copies of the Prospectuses as they may reasonably request for the purposes contemplated by the Securities Act of 1933. 

ARTICLE V. 
 CERTIFICATES
OF BENEFICIAL INTEREST 
 SECTION 1. The Trustee shall forthwith issue to such persons, firms or organizations (including the Trustee
acting in any representative or fiduciary capacity) as the Grantors may in writing direct, Certificates for an aggregate of 1,733,333 units of interest. Such Certificates and all other Certificates issued hereunder shall be in substantially the form
of Exhibit B hereto. 
 No Certificates for fractional units shall be issued. Fractional units of 1/2 or less shall be disregarded for all
purposes. In lieu of the issue of fractional units larger than 1/2, whole units shall be issued. 
 SECTION 2. The Certificate holders shall
be entitled to participate, according to the number of units of interest represented by and stated in their respective Certificates, in all the benefits of the trust estate, but each Certificate holder, whether said Certificate was acquired by
assignment or otherwise, shall take and hold the same subject to all the terms and provisions of this Indenture. Subject to the provisions of Section 4 of this Article V, by an assignment or transfer of any Certificate the assignor thereby
shall part with all his rights in, to and under the trust estate and any rights or benefits therein evidenced by such Certificate and under this Indenture as against all other Certificate holders and the Trustee. Said Certificates are and shall be
held and construed to be in all respects personal property and shall in no wise pass to or vest in any owner or holder thereof or his heirs, legatees or assignees as real estate and said Certificates shall be bequeathed, assigned, disposed of and
distributed as personal property. No Certificate holder as such shall have any legal title in or to the trust estate or any part thereof, the interest therein of each Certificate holder being subject to all the rights, powers, duties and obligations
of the Trustee to conserve, hold and dispose of the trust estate and to account for the same as in this Indenture provided. No Certificate holder shall have the right to call for or demand or secure any partition during the continuance of the Trust
hereby created. 
 SECTION 3. All Certificates shall be signed by a duly authorized officer of the Trustee and countersigned by the Transfer
Agent. The signature of the authorized officer of the Trustee and its seal may be facsimile in form. If any officer or officers of the Trustee whose signature may appear upon any of the Certificates shall cease to be such officer or officers of the
Trustee before such Certificates so signed and sealed shall have been authenticated or delivered by the Transfer Agent, such Certificates, upon such authentication and delivery, shall be valid and effective for all purposes as though the officer or
officers who signed and sealed the same had continued to be such officer or officers of the Trustee. Certificates may be signed and sealed on behalf of the Trustee by such persons as at the actual date of the signing and sealing of such Certificates
shall be the proper officers of the Trustee, although at the nominal date of such Certificates any such person shall not have been such officer of the Trustee. 

  
 Page 8 













 SECTION 4. The Certificate shall be transferable as against the Trustee only on the
registration books of the Transfer Agent and upon the surrender of such Certificates to the Transfer Agent duly endorsed by the holder thereof in good form for transfer in accordance with the regulations established by the Transfer Agent, and upon
payment of any transfer charges established by the Transfer Agent and approved by the Trustee. Until any such transfer, the Trustee may treat the owner of any Certificate as shown by the registration books of the Transfer Agent as the owner thereof
and shall not be charged with notice of any claim or demand to such Certificate or the interest represented thereby by any other party. Any such transfer of a Certificate shall, as to the Trustee, transfer to the transferee as at the date of
transfer all right, title and interest of the transferor in and to the trust estate and all parts thereof and all funds therein, either received or receivable, to which the transferor might then be entitled, provided that a transfer of a Certificate
after any Record Date determined as provided in Section 2 of Article VII hereof shall not transfer to the transferee the right of the transferor to any sum payable by the Trustee to him as the holder of record of the Certificate on said day.
Although the units of interest represented by the Certificates are not capital stock, for convenience it is stipulated that as to matters affecting title, ownership, warranty or transferability of the Certificates, the Uniform Commercial Code as
adopted and then in force in the State of Texas shall govern, except, as otherwise herein specifically provided. The death of any Certificate Holder shall not entitle the legal representative, heirs or assigns of such deceased Certificate Holder to
an account or valuation for any purpose, but such representatives, heirs or assigns shall succeed to all rights of the deceased Certificate Holder under this Indenture upon proper proof of title, satisfactory to the Trustee.
<PAGE>    22 
 SECTION 5. The Transfer Agent shall be a corporation or a national banking association having
offices in the geographical limits of the United States of America, and the Trustee may, in its discretion, act as Transfer Agent hereunder. The Transfer Agent shall maintain its registration books in its office. The Trustee may at any time remove
any Transfer Agent and, in the event of a vacancy resulting either from such removal or from the resignation of any Transfer Agent, a successor Transfer Agent shall be appointed by the Trustee, and as heretofore stated, the Trustee may appoint
itself to serve as Transfer Agent hereunder. All fees and charges of the Transfer Agent, including fees and charges of the Trustee, when serving as Transfer Agent, other than transfer charges to be paid by the transferring Certificate holder, as
provided in Section 4 of this Article V, shall be fixed and paid by the Trustee out of the trust estate at rates to be fixed by the Trustee, which shall be reasonable rates for such services. 

SECTION 6. If any Certificate shall become lost, destroyed or mutilated, the Trustee, in its discretion, and upon proper proof of title,
satisfactory to the Trustee, together with the surety bond sufficient in the opinion of the Trustee and the Transfer Agent to indemnify the Trustee and the Transfer Agent against all loss or expenses in the premises, and upon surrender of the
mutilated Certificate in case of mutilation, shall issue a new Certificate to the owner of such lost, destroyed or mutilated Certificate, upon payment of the reasonable charges of the Trustee and the Transfer Agent and any reasonable expenses
incurred by them in connection therewith. 
 SECTION 7. In the event of any disagreement between the transferees, legal representatives,
heirs or assigns succeeding to all or a part of the interest of any Certificate holder, resulting in adverse claims or demands being made in connection with such interest, the Trustee shall be entitled at its option to refuse to comply with any such
claims or demands so long as such disagreement shall continue. In so refusing, the Trustee may elect to make no delivery or other disposition of the interest represented by the Certificate involved, or any part thereof, or of any sum or sums of
money accrued or accruing thereunder, and in so doing the Trustee shall not be or become liable to any of said mentioned parties for the failure or refusal of the Trustee to comply with such conflicting or adverse claims and demands and the Trustee
shall be entitled to continue so to refrain and refuse so to act, until either 

  
 Page 9 













 (a) the rights of the adverse claimants have been adjudicated by a final
judgment of a court assuming and having jurisdiction of the parties and the interest and money involved, or 
 (b) all
differences have been adjusted by valid agreement between said parties and the Trustee shall have been notified thereof in writing signed by all of the interested parties. 

Upon distribution of any moneys so withheld by reason of conflicting or adverse claims or demands the Trustee may deduct therefrom the amount of all expenses,
including taxes, it shall have incurred as a result of withholding such distribution pending adjudication or settlement of such conflicting or adverse claims or demands. 

SECTION 8. Anything herein to the contrary notwithstanding, if within six (6) months from the effective date hereof none of the
Certificates to be issued hereunder shall have been offered for sale under the Securities Act of 1933, the Trustee may, in its discretion, thereafter act as Transfer Agent hereunder, and any provisions herein contained which are inconsistent with
such action shall from and after said date be null and void and of no effect. 
 ARTICLE VI. 

LIABILITY OF TRUSTEE AND METHOD OF SUCCESSION 

SECTION 1. The Trustee shall not be liable to any Grantor, Certificate holder or to any other person whomsoever for any loss, damage, claim,
demand or liability arising out of or in any way connected with the Trust or the Corporation or resulting from any act or omission of the Trustee in connection therewith, nor for any error of judgment made in good faith, except for its negligence or
willful misconduct or failure to account properly for funds and property actually received, nor shall the Trustee be liable for the acts or omissions of any independent agents appointed by said Trustee except for negligence in appointing such
agents. 
 SECTION 2. No officer, director or employee of the Corporation, who is or was at the time in question also an officer or employee
of the Trustee, shall be liable to any Grantor, Certificate holder or to any other person whomsoever for any loss, damage, claim, demand or liability arising out of or in any way connected with the management and administration of the affairs of the
Corporation, nor for any act or omission in connection therewith, nor for any error of judgment made in good faith, except for his own negligence, willful misconduct or failure to account properly for funds and property actually received, nor shall

trust estate except claims against the Trustee for its own negligence, willful misconduct or failure to account properly for funds and property actually received by it, shall, if established, be satisfied out of the trust estate and under no
circumstances shall be the personal obligation of the Trustee. If any such liability satisfiable out of the trust estate should be asserted against the Trustee, the Trustee may use such part of the trust estate as may be necessary in contesting any
such liability and in payment thereof. The Trustee may take such action and incur such expenses as it may in its sole discretion deem advisable in connection with any such claim and likewise may effectuate a compromise thereof. 

SECTION 4. In no event shall the Trustee be obligated to take any action as Trustee under this Indenture which in its opinion might subject it
to any expense or liability whatsoever unless, in the opinion of the Trustee, sufficient funds or property, available for reimbursement and indemnification, are present in the trust estate with which to reimburse or indemnify the Trustee; but
neither the presence in the trust estate of such funds or property, nor the furnishing of same by others, shall obligate the Trustee to take any action which it may deem improper under this Indenture. No bond shall ever be required of the Trustee.

 SECTION 5. The Trustee may, but shall not be required to, consult with counsel (who may be
its own counsel), accountants, engineers and other parties deemed by the Trustee to be qualified on the matters submitted to them, and the opinion of any such parties on any matter submitted to them by the Trustee shall be full and complete
authorization and protection to the Trustee and the Trustee shall not be liable to any person for any act taken, suffered or omitted by it hereunder in good faith in accordance with the opinion of any such party. 

SECTION 6. The Trustee may resign at any time by written notice to each of the Certificate holders, given by mail addressed to each such
holder at his last known post office address as shown by the registration books of the Transfer Agent. Such notice shall be duly acknowledged in the form required under the laws of Texas for the acknowledgment of deeds, and shall specify a date when
such resignation shall take effect, which shall be a business day not less than thirty (30) days from the date such notice is mailed. The registration of the Trustee shall be effective on the date specified in the notice regardless of whether a
successor Trustee has then been appointed. 
 SECTION 7. The Trustee may be removed at any time upon written direction or directions signed
by Certificate holders owning a majority of the outstanding units of interest. A Trustee so removed shall forthwith be paid any and all compensation, fees, expenses, and other sums of money to which it may then be entitled, and shall be entitled to
withdraw such funds from the trust estate. 
 SECTION 8. In the event of a vacancy in the position of Trustee or in the event the Trustee in
its resignation has designated a date in the future at which such resignation shall become effective, Certificate holders owning a majority of the outstanding units of interest may, by written direction or directions, appoint a successor Trustee.
Any successor Trustee shall be a national bank, state bank or trust company having its principal office in the United States and having an unimpaired capital and surplus of not less than Three Million Dollars ($3,000,000.00). In the event a vacancy
in the position of Trustee continues for sixty (60) days, a successor Trustee may be appointed by the Junior District Judge of the United States District Court for the Northern District of Texas, Dallas Division (if he fails or refuses to act,
then by the Senior Judge of the District Courts of Dallas County, Texas), upon the ex parte application of the resigning Trustee, or any Certificate holder; and in the event any such application is filed, such Judge may appoint, at any time
thereafter, a temporary Trustee having the qualifications specified in this Section, and such temporary Trustee shall, pending the final appointment of a successor Trustee, have such powers and duties as the Judge appointing such temporary Trustee
shall provide in the order of appointment, consistent with the provisions of this Indenture. 
 Immediately upon the appointment of any
successor Trustee, all rights, titles, duties, power and authority theretofore held by the retiring Trustee hereunder shall be imposed upon, vested in and undertaken by the successor Trustee, and the successor Trustee, upon delivering to the
retiring Trustee adequate receipts, releases and acquittances, shall be entitled to receive from the retiring Trustee all of the trust estate held by it and all records and files in connection therewith. 

ARTICLE VII. 
 ACCOUNTING
FOR INCOME OF TRUST ESTATE 
 SECTION 1. The Trustee may and shall at any time and from time to time use so much of all money received
by it as may be necessary to pay all liabilities and obligations incurred by it in connection with the administration of the trust estate, including, without limiting the generality of the foregoing, all expenses, taxes and liabilities incurred of
all kinds, including expenses of the Corporation, compensation to the Trustee for its services hereunder and compensation to such parties as may be employed or used by the Trustee as herein provided; provided, however, that the expenses of
establishing this Trust shall not be considered an expense of the trust estate. 

  
 Page 11 













 SECTION 2. On the 28th day of March, June, September and December of each year, or on the
next succeeding business day if any such date is a Saturday, Sunday or legal holiday, the Trustee shall make distributions to the Certificate Holders, pro rata in proportion to the number of units of interest represented by their respective
Certificates, of all cash in the trust estate as of the close of the last business day of the preceding month (herein called the “Record Date”), such payment to be made to the Certificate Holders of record on the registration books of the
Transfer Agent at the close of business on the Record Date, less such amounts of money not in excess of $2,000 as the Trustee may reasonably determine should be reserved for the payment of estimated liabilities and expenses of the trust estate, and
less such amounts as may be allocable to any units of interest the ownership of which are in question. Payments shall be made by mailing to each Certificate Holder a check drawn on the bank in which trust funds are deposited for the amount to be
paid to each Certificate Holder. With each such check the Trustee shall send to each Certificate Holder a statement showing in summary form, on a per unit basis, the receipts and disbursements of the Trustee during the period from the last previous
Record Date to the Record Date as of which the payment being made was computed. Such statement shall contain such information as is reasonably available to the Trustee and as it may consider to be helpful in determining the amount of taxable income
that such person should include in his Federal Income tax return on account of the payments then being made by the Trustee. If any of the Certificates issued hereunder shall be offered for sale under the Securities Act of 1933, the Trustee shall
file with the Securities and Exchange Commission copies of all statements mailed pursuant to the requirements of the foregoing sentence and copies of all other communications which it may send to Certificate Holders. 

ARTICLE VIII. 

INDEMNIFICATION, REIMBURSEMENT AND COMPENSATION OF THE TRUSTEE 

SECTION 1. The Trustee shall be indemnified by, and receive reimbursement from the trust estate against and from any and all personal
liability, claims, damages or loss incurred by it in the administration of the trust estate or any part thereof, or in the doing of any act of omission or commission done or performed by it as Trustee hereunder, and the Trustee shall have a first
lien upon the trust estate to secure it for such indemnification and reimbursement, as well as for the compensation to be paid the Trustee hereunder; provided, however, that nothing in this Section shall entitle the Trustee to any indemnification or
reimbursement or to any lien therefor on account of any claim, damage or loss arising out of, or any act of omission or commission constituting negligence or willful misconduct or failure to account properly for funds actually received. 

SECTION 2. The Trustee and the Transfer Agent shall be protected, and shall not be liable to any one whomsoever, in acting upon any notice,
credential, certificate, assignment, transfer, or other document or instrument believed by them, or either of them acting on the same, to be genuine and to be signed by the proper party or parties.

MISCELLANEOUS 
 SECTION 1.
Each Certificate holder of record and his duly authorized agents, attorneys and auditors shall have the right, during reasonable business hours, to examine, inspect and audit the records of the Trustee relating to the trust estate and the records of
the Corporation. 
 SECTION 2. Neither this Indenture nor any executed copy hereof need be filed in any county in which any of the trust
estate is located, but the same may be filed for record in any county, agency, registry or jurisdiction by the Trustee. In order to avoid the necessity of filing this Indenture for record, the Trustee agrees that for the purpose of vesting the
record title in any successor Trustee, the retiring trustee will, upon appointment of any successor Trustee, execute and deliver to any successor Trustee appropriate assignments and conveyances preserving and continuing the terms and provisions of
the Assignment and Conveyance attached hereto as Exhibit A. 
 SECTION 3. In the event any person refuses or threatens to refuse to perform
any obligation contained in any contract, agreement or undertaking constituting a part of the trust estate on the ground that such contract, agreement or undertaking violates the rule of law known as the “Rule against Perpetuities,” the
Trustee is authorized and empowered, on behalf of the Grantors and Certificate holders, to amend and modify such contract, agreement or undertaking to the extent necessary to conform to, and be valid under, such rule of law for the longest possible
period of time. 

  
 Page 13 













 SECTION 4. Insofar as may be provided, it is hereby provided that this Trust shall not be
subject to the provisions of the Texas Trust Act as it may now or hereafter be written. In all other respects, this Indenture shall be deemed to be a contract made under, and shall be construed in accordance with, the laws of the State of Texas.

 SECTION 5. When authorized and directed in writing by Certificate holders owning eighty per cent (80%) of the outstanding units of
interest, the Trustee shall, on behalf of the Grantors and Certificate holders, amend and modify any contract, agreement or undertaking which, or an interest in which, constitutes a part of the trust estate; provided, however, that no such amendment
or modification shall in any way change the nature of this trust from that of a purely ministerial trust, nor shall any such amendment or modification be in any way inconsistent with the purpose of this Indenture, nor shall such amendment or
modification change the rights, duties or responsibilities of the Trustee without the consent of such Trustee; and provided, further, that no such amendment or modification shall reduce or diminish the rights and interests of the Trust in any such
contract, agreement or undertaking, or the money, income, gains and revenues accruing to the trust estate thereunder. 
 SECTION 6. When
authorized and directed in writing by Certificate holders owning a majority of the outstanding units of interest, the Trustee shall, on behalf of the Grantors and Certificate holders, vote the shares of stock of the Corporation in favor of
dissolution of the Corporation and the transfer of its properties to the Trustee as a part of the trust estate. 
 SECTION 7. Whenever
provision is made herein for the giving of notices to Certificate holders by the Trustee, the persons to whom such notices shall be given by the Trustee and the persons entitled to act with respect to any such notices shall be determined by
reference to the registration books of the Transfer Agent with respect to the persons holding certificates as of the close of business on the 10th business day prior to the date on which such notices from the Trustee to Certificate holders are first
placed in the mail by the Trustee. 
 Whenever provision is made herein for the taking of action pursuant to or upon the authorization,
direction or consent of Certificate holders owning a specified percentage of the outstanding units of interest, such authorization, direction or consent shall be evidenced by an instrument or instruments in writing, all of which instruments shall be
dated as of the same date (which date is hereinafter referred to as the “date of record” and which date may be a date other than the date of execution of the instrument by the Certificate holder giving the authorization, direction or
consent) and the required percentage of such Certificate holders and the persons entitled to act with respect to any proposed authorization, direction or consent and to whom notices thereof shall be given, shall be determined by reference to the
registration books of the Transfer Agent with respect to the persons holding Certificates as of the close of business on the date of record; provided that no such instrument in writing evidencing such authorization, direction or consent shall be
effective for the purposes thereof unless received by the Trustee within 45 days after the date of record. 
 SECTION 8. In the event any of
the provisions contained in this Indenture should be held invalid by a final judgment of a court with jurisdiction in the premises, the invalidity of any such provision shall not affect the validity of any other provision hereof.

 ARTICLE X. 

TERMINATION OF TRUST 

SECTION 1. The Trust hereby created shall continue until June 1, 2041, provided that: 

(a) Certificate holders owning a majority of the outstanding units of interest may, by written consent or consents, extend the
term of this Trust for an additional period of not more than twenty (20) years from the date fixed in such written consent. 

(b) Certificate holders owning a majority of the outstanding units of interest may, by written consent or consents, authorize
and direct the Trustee to organize and create one or more corporations to receive and hold title to the property, property rights and interests then comprising the trust estate, or any portion thereof, as such Certificate holders shall authorize and
direct, and to administer the same in the place of the Trustee; provided, however, that there shall be no such action if the Trustee shall receive written objection to such action from any Certificate holder within twenty (20) days from the
date of mailing to the Certificate holders of the first notice of the proposed consent. In the event such a corporation is organized: 
 1.
Such corporation shall be organized under the laws of and in such jurisdiction and with such powers as such Certificate holders shall in such written consent or consents authorize and approve. 

2. Each Certificate holder shall own an interest in such corporation in the same proportion as his units of interest under this Trust bears to
all of the units of interest under this Trust outstanding upon a date fixed by such Certificate holders in such written consent or consents, and the shares of such corporation shall be distributed at the time and in the manner prescribed in such
written consent or consents. 
 3. The Trustee shall assign and convey to such corporation such property, property rights and interests then
comprising the trust estate as such Certificate holders shall authorize and direct in such written consent or consents; and such corporation shall assume such outstanding debts, obligations and liabilities of the Trustee and trust estate as such
Certificate holders shall authorize and direct in such written consent or consents. 
 Upon the organization of such corporation, the
issuance of its capital stock, the transfer and conveyance of it of property, property rights and interests of the trust estate and the assumption by it of debts, obligations and liabilities of the Trustee and the trust estate, all as above
provided, this Trust shall no longer apply to such property, property rights and interests and the Trustee shall be under no further liability or obligations with respect to the property, property rights and interests so assigned and conveyed to
such corporation. If all of the property, property rights and interests of the trust estate are assigned and conveyed to such corporation or corporations and all of the debts, obligations and liabilities of the Trustee and trust estate are assumed
by such corporation or corporations, this Trust shall terminate and the Trustee shall be under no further liability or obligation whatever. 

(c) No amendment to this Indenture shall in any way change the nature of this Trust from that of a purely ministerial trust.
Subject to this limitation, Certificate holders owning eighty per cent (80%) of the outstanding units of interest may, by written consent or consents, amend this Indenture in such manner as shall be provided in such written consent or consents;
provided, however, that there shall be no change in the rights, duties or responsibilities of the Trustee without the consent of such Trustee; and provided, further, that no such change shall be made if the Trustee shall receive written objection to
such change from any Certificate holder within twenty (20) days from the date of mailing to the Certificate holders of the first notice of the proposed consent. 

(d) Certificate holders owning eighty per cent (80%) of the outstanding units of interest may, by written consent or consents,
terminate this Trust at such date as may be fixed in such written consent or consents. 

  
 Page 15 













 Upon termination of this Trust by lapse of time or action of Certificate holders,
Certificate holders owning a majority of the outstanding units of interest shall designate, by written consent or consents, an agent to receive all subsequent conveyances and payments and to distribute the same among the persons entitled thereto.

 SECTION 2. Anything herein to the contrary notwithstanding, this Trust shall in any event terminate not later than twenty-one (21) years from and after the death of the last survivor of all of the individual persons who as Grantors execute this Indenture and establish this Trust and who are living at the effective date of
this Trust. 
 In the event it should be finally determined by any court, tribunal, or other authority having jurisdiction so to determine
that the immediately foregoing paragraph of this Section 2 is invalid for any reason, including the reason that the number of individual persons who as Grantors execute this Indenture and establish this Trust and are living at the effective
date of this Trust are either so numerous or so situated that evidence of their deaths is likely to be unreasonably difficult to obtain, then, in that event only, and anything herein to the contrary notwithstanding, this Trust shall terminate not
later than twenty-one (21) years from and after death of the last survivor of the following persons, all of whom are Grantors hereunder, to-wit: 

L. C. Paslay 
 J. H. Pernell 

Chas. G. McBurney 
 Geo. M. Pavey,
Jr. 
 Patricia L. Paslay 
 Neal
W. Morris 
 and the lineal descendants of each of said persons living at the effective date of this Trust. 

SECTION 3. For the purpose of liquidating and concluding the affairs of this Trust at its termination otherwise than by action taken pursuant
to Section 1(b) of this Article X, the Trustee shall continue to act as such until its duties have been fully performed, subject to the right of resignation and removal. At such time, after paying, satisfying and discharging all of the debts,
liabilities, and obligations of the trust estate, the Trustee shall make distribution of the trust estate according to the respective interests and rights of the Certificate holders, executing and delivering to the persons entitled thereto all
instruments of assignment and conveyance, without, however, any warranty of title, as are necessary and required to transfer to each Certificate holder legal title to his undivided share of the property then comprising the trust estate, in return
for the surrender of his outstanding Certificates. After so doing, the Trustee shall be under no further liability. 
 ARTICLE XI.

 ESCROW OF A PORTION OF GRANTORS’ INTEREST 

SECTION 1. There is pending in one of the District Courts of Dallas County, Texas, a suit numbered
4966-F styled `R. A. Irwin v. L. C. Paslay, et al.’ Because of the pendency of such suit, certain portions of the property, property rights and interests which would otherwise have been assigned and
conveyed to the Trustee hereunder and made a part of the trust estate have not been so assigned and conveyed, such portion aggregating a 10/75ths interest of the parties creating this Trust in each of the following items of property comprising the
trust estate, viz., the items described in Paragraphs A.l, A.2, A.3, B.5, B.6, B.7, C.8, D.9, and H.13 of ARTICLE II of this Indenture. Concurrently with the execution of this Indenture and the assignment and conveyance to the Trustee of the
property, property rights and 

  
 Page 16 













 
interests constituting the trust estate, including 65/75ths interest of the parties creating this Trust in each of the items of property comprising the trust estate heretofore referred to,
Grantors, except Alex Pope, Jr. and Louis H. Haring, have executed an additional Assignment and Conveyance, dated as of June 1, 1956, as amended and supplemented by a Supplemental Assignment and Conveyance, dated as of June 1, 1956, and
other instruments of transfer in favor of the Trustee covering said 10/75ths interest not yet included in the trust estate, which Assignment and Conveyance, as amended and supplemented, and other instruments of transfer have been delivered to
Republic National Bank of Dallas, as Depositary (hereinafter referred to as the `Depositary’), to be held temporarily by said Depositary and subsequently to be delivered pursuant to the terms of a certain Depositary Agreement, a copy of which,
exclusive of signatures and acknowledgments, is annexed hereto as Exhibit C and by reference made a part hereof, as supplemented and amended by a certain Supplemental Depositary Agreement, designated as Part B of an Agreement dated as of
June 1, 1956, between the Depositary, Grantors and others, which agreement is by reference made a part hereof. The property, property rights and interests covered by said Assignment and Conveyance, as supplemented and amended by the
Supplemental Assignment and Conveyance, are hereinafter sometimes called `the escrowed properties,’ and the separate items of property included therein are sometimes referred as having been `placed in escrow’. The execution and delivery of
the Depositary Agreement, as amended and supplemented, and the execution and delivery of the Assignments and Conveyances, as so amended and supplemented, and other instruments of transfer constituting the `Deposited Property’, as defined in the
Depositary Agreement, as amended and supplemented, are irrevocable, and each Grantor, upon the acceptance of the considerations and benefits of this Indenture, is precluded from rescission or revocation of the Depositary Agreement, as amended and
supplemented, and the conveyances delivered in connection therewith. 
 SECTION 2. If and when the above-styled suit has been finally
determined and all other suits and adverse claims pending at the time of determination of said suit, if any, have been likewise determined, and all judgments entered against any of the Grantors as a result of any of such suits have been satisfied in
such a manner as to permit inclusion of all of the escrowed properties in the trust estate in the manner provided in said Depositary Agreement, as amended, the Assignment and Conveyance to the Trustee, as amended and supplemented by the Supplemental
Assignment and Conveyance dated as of June 1, 1956, and the other instruments of transfer deposited with the Depositary shall be delivered by the Depositary to the Trustee concurrently with the delivery by the Depositary to Marine Petroleum
Corporation of certain other instruments also deposited in escrow, all as provided in the Depositary Agreement, as amended and supplemented, and the property, property rights and interests covered by this said Assignment and Conveyance to the
Trustee, as so amended and supplemented, shall thereafter be and become a part of the trust estate. Upon receipt of the Assignment and Conveyance, as so amended and supplemented, and the other instruments of transfer, the Trustee shall issue to the
Grantors, their heirs, executors, administrators or assigns, Certificates representing an aggregate of 266,667 units of interest, as provided in the Depositary Agreement, as supplemented, and in accordance with the directions contained in said
Assignment and Conveyance. 
 SECTION 3. If and when the above-styled suit has been finally determined and all other suits and adverse
claims pending at the time of determination of said suit, if any, have been likewise determined and all judgments entered against any of the Grantors as a result of the above-styled suit or any other such suits have been satisfied in such manner as
to prevent inclusion of all of the escrowed properties in the trust estate, a portion of the escrowed properties may, nevertheless, within one year from the final determination of the last of such suits to be determined, be assigned and conveyed to
the Trustee and included in the trust estate, if all the following terms, conditions and limitations are satisfied: 
 (a)
Any Grantor or any group of the Grantors, their heirs or personal representatives, may at any time and from time to time during said one-year period, execute and deliver to the Trustee an assignment and
conveyance of a portion of the escrowed properties, provided that such assignment and conveyance or assignments and conveyances in each instance cover an interest in each separate item of property comprising the escrowed properties, and provided
further that all of the other conditions of this Section 3 are satisfied; 

  
 Page 17 













 (b) to the extent that the quantum of interest (number of units, number of
fractional interests, or number of shares, as the case may be) of any such separate item of property to be transferred to the Trustee under this Section 3 is less than the quantum of interest of such item of property originally placed in
escrow, then the quantum of interest (number of units, number of fractional interests, or number of shares, as the case may be) of each other separate item of property included in the assignment and conveyance to the Trustee shall be proportionately
reduced so that the quantum of interest (number of units, number of fractional interests, or number of shares, as the case may be) of every separate item of property shall bear the same ratio to each of the other items of property as the quantum of
interest of each of the separate items of property originally placed in escrow bore to each other. For example, 60,316 shares of beneficial interest in Tidelands Royalty Trust “B” have been originally placed in escrow; accordingly, if
30,158 of such shares are included in the assignment and conveyance contemplated in this Section, being 1/2 of the number of such shares originally placed in escrow and being 50% of the quantum of interest in such item of property originally placed
in escrow, 50% of the quantum of interest placed in escrow of each other item of property may be included in such assignment and conveyance, viz., an undivided 2.4864876 interest in the overriding royalty interest conveyed to Marine Instrument
Company and others by the Atlantic Refining Company and others, an undivided 2.4864876 interest in and to all of the rights, privileges and benefits under the Atlantic Agreement, 29,166 units in Tidelands Agency Agreement “A”, an undivided
5% interest in and to all the rights, privileges and benefits under each of the Gulf Agreements, 50,000/1,000,000ths fractional interests in each of the Temporary Indentures, an undivided 5/75ths of the interest of TEMPORARY TRUSTEE in each of the
Temporary Indentures, an undivided 5/75ths interest in and to all the rights, privileges and benefits under the Supplemental Gulf Agreement, an undivided 5/75ths interest in and to all of the rights, privileges and benefits under the Texas Gulf
Agreement and 30,158 shares of beneficial interest in Tidelands Royalty Trust “B”; upon acceptance by the Trustee of an assignment and conveyance covering such properties in the amounts stated in this example, the Trustee shall issue to
such persons, firms or organizations as the persons executing such assignment and conveyance may in writing direct, Certificates for an aggregate of 133,333 units of interest; it being the purpose of this subsection (b) and of the essence in
making provision herein for the transfer of a portion of the escrowed properties to the Trustee, that the interest in the trust estate of a Certificate holder at or prior to such assignment and conveyance shall not be diluted but that following such
assignment and conveyance each such Certificate holder shall thereafter own the same proportionate interest in each of the separate items of property constituting the trust estate as he owned prior to such assignment and conveyance; 

(c) concurrently with delivery to the Trustee of such assignment and conveyance or assignment and conveyances the parties
executing the same shall execute and deliver to Marine Petroleum Corporation, a Texas corporation, an assignment and conveyance in substantially the same form as the assignment and conveyance to the Trustee, covering a like quantum of interest in
and to (i) each of the Gulf Agreements, (ii) each of the Temporary Indentures, (iii) the Supplemental Gulf Agreement, and (iv) the Texas Gulf Agreement, respectively, insofar, but only insofar, as said property, property rights
and interests pertain to or affect lands within the State of Louisiana and the lands which would be within the area of the State of Louisiana if its boundaries were extended seaward to the outer margin of the outer Continental Shelf in the Gulf of
Mexico, term “outer Continental Shelf” herein having the meaning contained as of the date hereof in Section 2(a) of the United States Outer Continental Shelf Lands Act (hereinafter sometimes referred to as the ‘Louisiana
Lands’), such assignment and conveyance to Marine Petroleum Corporation heretofore defined in substantially the same manner as such reservation is expressed in the Assignment and Conveyance to said Corporation, dated as of June 1, 1956,
delivered to the Corporation concurrently herewith. 

  
 Page 18 













 (d) concurrently with delivery to the Trustee and Marine Petroleum
Corporation of said assignments and conveyances, the parties executing such assignments and conveyances shall furnish a favorable opinion of Thompson, Knight, Wright & Simmons, of Dallas, Texas, or their successors, or of other counsel
acceptable to the Trustee, to the effect that: (i) said assignments and conveyances, upon delivery, will be effective to vest good and marketable title to said property, property rights and interests in the Trustee and Marine Petroleum
Corporation, respectively, in accordance with their terms, (ii) said property, property rights and interests are free and clear of all pledges, liens and encumbrances of record, (iii) the transfers of the portion of the escrowed properties
to the Trustee and Marine Petroleum Corporation, respectively, have been made in compliance with the provisions of the Indenture and the Supplemental Indentures, and (iv) no dilution will result to the interest of any Certificate holder who was
a holder at or prior to the transfer of the said additional properties. The opinion of counsel, however, may be made subject to the same kind of exceptions, reservations and comments that are contained in the opinion of counsel delivered to the
Trustee upon execution and delivery of the Indenture. 
 (e) upon acceptance by the Trustee of any such assignment and
conveyance, accompanied by the opinion described in sub-paragraph (d), Trustee shall issue to such persons, firms or organizations (including the Trustee acting in any representative or fiduciary capacity) as
the persons executing such assignment and conveyance may in writing direct, Certificates for an aggregate number of units of interest (less than 266,667) which is in the same ratio in the quantum of interest of each of the separate items of property
included in said assignment and conveyance as 266,667 bore to the quantum of interest of each of the separate items of property originally placed in escrow, that is to say, the aggregate number of units of interest to be issued under this subsection
(e) shall be proportionately reduced from 266,667 to the same extent that is provided in subsection (b) of this Section for reducing the quantum of interest of each separate item of property originally placed in escrow; 

(f) each of said assignments and conveyances to the Trustee and to Marine Petroleum Corporation shall be joined in by the
persons presently doing business as partners under the partnership name of Marine Instrument Company, their successors or assigns, and the TEMPORARY TRUSTEE, his successors or assigns, and shall cover the interest of the TEMPORARY TRUSTEE in each of
the Temporary Indentures as said Temporary Indentures pertain to or affect Texas Lands and Louisiana Lands, respectively, the quantum of interest of the TEMPORARY TRUSTEE to be assigned and conveyed in each assignment and conveyance to be determined
in the manner heretofore provided in subsection (b) of this Section for determining the quantum of interest to be assigned and conveyed with respect to the items of property therein described; 

(g) the Trustee and Marine Petroleum Corporation, in accepting the assignments and conveyances provided for in this Section,
and in including the property, property rights and interests covered thereby in the trust estate and in issuing Units and Certificates, may rely in good faith upon the opinion of counsel to the effect that the Trustee and Marine Petroleum
Corporation are acting in accordance with the provisions of this Section. 
 SECTION 4. If and when the above-styled suit has been finally
determined in the manner provided in Section 2 of this ARTICLE XI to permit inclusion of all the escrowed properties in the trust estate, but nevertheless, because of breach of contract, failure of title, or any other cause, Depositary fails or
refuses 

  
 Page 19 













 
or is not authorized to deliver the Assignments and Conveyances deposited to the Trustee and <PAGE> 51 Marine Petroleum Corporation, then any GRANTOR or group of GRANTORS may, within one
year from the final determination of such suit, assign and convey to the Trustee a portion of the escrowed properties upon the terms, conditions and limitations provided in Section 3 of this ARTICLE XI. 

SECTION 5. The Depositary Agreement is to remain in effect until the final determination of the above-styled suit and any other suits and
adverse claims affecting any of the items of property an interest in which is a part of the trust estate pending at the time of determination of said suit and the satisfaction of any judgments entered in favor of the Plaintiff in said suit and in
favor of any other claimants in such other suits or until the termination of this trust, whichever is earlier. All costs and expenses in connection with the inclusion in the trust estate of all or part of the escrowed properties and the issue of
units of interest shall be borne by the persons to whom such Certificates are issued. Except as provided in this ARTICLE XI, the Trustee shall at no time issue Certificates representing more than the 1,733,333 units of interest specified in
Section 1 of ARTICLE V hereof. Upon issuance of any Certificates under this ARTICLE XI, the Trustee shall promptly give notice thereof to all Certificate holders.
