to be Buyer's election to take the action described in clause (a) above. If Buyer elects to terminate this Agreement as provided
in clause (b) above, this Agreement shall automatically terminate, the parties shall be released from all further obligations under
this Agreement (except pursuant to any provisions which by their terms survive a termination of this Agreement), the Deposit shall
be immediately returned to Buyer and Buyer shall immediately return to Seller or destroy all Property Information and Seller may
terminate Buyer’s access to the Data Room.

as required by law, by court order, or in connection with any subpoena served upon Buyer or Seller; provided Buyer and Seller shall
provide each other with written notice before making any such disclosure. Notwithstanding the foregoing and anything to the contrary
in this Agreement, nothing contained herein shall impair Seller's (or any Seller affiliate's) right to disclose information relating

shall cooperate with Buyer in connection with any filings against or negotiations with the tenant involved and Buyer’s indemnity

or renewal if it has not notified Seller specifying with particularity the matters to which Buyer reasonably objects, within 5

or the new lease.

 

    	 	7	 

     

    

  

5.4       Damage
or Condemnation. Risk of loss resulting from any condemnation or eminent domain proceeding which is commenced or has been
threatened against the Property before the Close of Escrow, and risk of loss to the Property due to fire, flood or any other cause
before the Close of Escrow, shall remain with Seller. If before the Close of Escrow the Property or any portion thereof shall be
materially damaged, or if the Property or any material portion thereof shall be subjected to a bona fide threat of condemnation
or shall become the subject of any proceedings, judicial, administrative or otherwise, with respect to the taking by eminent domain
or condemnation, then Buyer may elect not to acquire the Property by delivering written notice of such election to Seller within
twenty (20) days after Buyer learns of the damage or taking, in which event Buyer shall no longer be obligated to purchase, and
Seller shall no longer be obligated to sell, the Property, in which event the Deposit will be immediately returned to Buyer. If
the Closing Date is within the aforesaid 5-day period, then the Close of Escrow shall be extended to the next business day following
the end of said 5-day period. If no such election is made, and in any event if the damage is not material, this Agreement shall
remain in full force and effect, the purchase contemplated herein, less any interest taken by eminent domain or condemnation, shall
be effected with no further adjustment, and upon the Close of Escrow, Seller shall assign, transfer and set over to Buyer all of
the right, title and interest of Seller in and to any awards that have been or that may thereafter be made for such taking, and
Seller shall assign, transfer and set over to Buyer any insurance proceeds that may thereafter be made for such damage or destruction
giving Buyer a credit at the Close of Escrow for any deductible under such policies. For purposes of this Section 5.4, the
phrase(s) (i) "Material damage" or "Materially damaged" means (a) damage reasonably exceeding $500,000.00,
(b) damage that materially adversely affects access or parking for the Real Property or (c) any damage which is not fully insured
and for which Buyer will not receive, at Seller's election in its sole discretion, a credit in the amount of the uninsured portion
of such damage upon the Close of Escrow, and (ii) "material portion" means any portion of the Property that has a "fair
market value" exceeding $500,000.00 or that if lost through condemnation would materially adversely affect the use of the
Real Property or access or parking at the Real Property.

		10.	PRORATIONS.

 

The parties shall allocate and prorate
all the income and expenses of the Property as of 12:01 a.m. local time on the Closing Date, as if Buyer were vested with title
to the Property during the entire day upon which the Close of Escrow Occurs, as set forth below.

 

10.1     Collected
Rent. All rent (including, without limitation, all base rents, additional rents and retroactive rents, and expressly excluding
tenant reimbursements for Operating Costs, as hereinafter defined) and all other income (and any applicable state or local tax
on rent, other than income taxes) (hereinafter collectively referred to as "Rents") collected under Leases in effect
on the Closing Date shall be prorated as of the Close of Escrow. Uncollected Rent shall not be prorated and, to the extent payable
for the period prior to the Close of Escrow, shall be the property of Buyer. Seller shall not pursue collection of any Rents that
were past due as of the Closing Date.

 

10.2     Operating
Costs and Additional Rent Reconciliation. Seller, as landlord under the Leases, is currently collecting from tenants under
the Leases additional rent to cover taxes, insurance, utilities (to the extent not paid directly by tenants), common area maintenance
and other operating costs and expenses (collectively, "Operating Costs") in connection with the ownership,
operation, maintenance and management of the Real Property. At the Close of Escrow, a portion of the purchase price equal to the
lesser of (a) $275,000 or (b) a lesser reasonable amount to be agreed upon by the parties prior to Closing (the “Escrowed
Funds”), shall remain in escrow with the Escrow Holder until the expiration of the applicable Operating Costs reconciliation
periods under the Leases to account for the reconciliation of additional rent (including, without limitation, estimated payments
for Operating Costs) paid by tenants to the landlord under the Leases based on an estimated payment basis (monthly, quarterly,
or otherwise) for which a future reconciliation of actual Operating Costs to estimated payments is required to be performed at
the end of a reconciliation period. If, as of the expiration of the applicable reconciliation period under the applicable Lease,
Seller has received additional rent payments in excess of the amount that tenants were required to pay under the Lease during the
period that Seller was the landlord under the applicable Lease, based on the actual Operating Costs paid by Seller as of the Close
of Escrow, Escrow Holder shall disburse to Buyer an amount equal to such excess. If, as of the expiration of the applicable reconciliation
period under the applicable Lease, Seller has received additional rent payments that are less than the amount that tenants would
be required to pay during the period that Seller was the landlord under the applicable Lease based on the actual Operating Costs
paid by Seller as of the Close of Escrow, Buyer shall pay to Seller the amount of such deficiency, to the extent, and only to the
extent, that Buyer receives such deficiency from the tenant under the applicable Lease. Buyer and Seller shall each execute and
deliver written instructions to Escrow Holder as and when required to effectuate the disbursements of the Escrowed Funds in accordance
with this Section 10.2. The provisions of this Section 10.2 shall survive the Close of Escrow without limitation.

 

10.3     Taxes
and Assessments. Real estate taxes and assessments imposed by any governmental authority ("Taxes")
with respect to the Real Property and Improvements for the relevant tax year in which the Real Property is being sold and that
are not yet due and payable or that have not yet been paid and that are not (and shall not be) reimbursable by tenants under the
Leases as Operating Costs shall be prorated as of the Close of Escrow based upon the most recent ascertainable assessed values
and tax rates and based upon the number of days Buyer and Seller will have owned the Real Property during such relevant tax year.
Seller shall receive a credit for any Taxes paid by Seller and applicable to any period after the Close of Escrow.

 

    	 	12	 

     

    

  

10.4     Leasing
Commissions and Tenant Improvements and Contracts. Schedule 10.4 attached hereto sets forth improvement allowances, free
rent, and other all leasing costs arising under the Leases and unpaid as of the Closing Date or arising or due after the Closing
Date (“Leasing Costs”). At Close of Escrow, Buyer shall assume (pursuant to the Assignment of Leases)
the obligation to pay all Leasing Costs. Buyer shall be entitled to a credit against the Purchase Price equal to the amount of
Leasing Costs. To the extent, and only to the extent, any Leasing Costs are included in the Cure Costs pursuant to Section 4.7.3,
such amounts included in the Cure Costs shall be excluded from the amount to be assumed by Buyer and the corresponding credit due
Buyer at Closing pursuant to this Section 10.4.

 

10.5     Tenant
Deposits. All tenant security deposits actually received by Seller (and interest thereon if required by law or contract
to be earned thereon) and not theretofore applied to tenant obligations under the Leases shall be transferred or credited to Buyer
at the Close of Escrow or placed in escrow if required by law. To the extent, and only to the extent, any security deposits due
under this Section 10.5 are included in the Cure Costs pursuant to Section 4.7.3, such amounts included in the Cure Costs shall
be excluded from the amount of the credit due Buyer at Closing pursuant to this Section 10.5. As of the Close of Escrow, Buyer
shall assume Seller's obligations related to tenant security deposits. Buyer will indemnify, defend, and hold Seller harmless from
and against all demands and claims made by tenants arising out of the transfer or disposition of any security deposits properly
transferred or credited to Buyer.

 

10.6     Utilities
and Utility Deposits. Utilities for the Real Property (excluding utilities for which payment is made directly by tenants),
including water, sewer, electric, and gas, based upon the last reading of meters prior to the Close of Escrow, shall be prorated.
Seller shall be entitled to a credit for all security deposits held by any of the utility companies providing service to the Real
Property and assigned to Buyer. Seller shall endeavor to obtain meter readings on the day before the Closing Date, and if such
readings are obtained, there shall be no proration of such items and Seller shall pay at Close of Escrow the bills therefor for
the period to the day preceding the Close of Escrow, and Buyer shall pay the bills therefor for the period subsequent thereto.
If the utility company will not issue separate bills, Buyer will receive a credit against the Purchase Price for Seller's portion
and will pay the entire bill prior to delinquency after Close of Escrow. If Seller has paid utilities no more than 30 days in advance
in the ordinary course of business, then Buyer shall be charged its portion of such payment at Close of Escrow. Buyer shall be
responsible for making any security deposits not credited to Seller and required by utility companies providing service to the
Real Property.

to purchase the Real Property from Seller, Seller makes the following representations and warranties to Buyer:

 

(a)       Seller

Bankruptcy Court Sale Order, Seller has the legal right, power and authority to enter into this Agreement and to consummate the

is no agreement to which Seller is a party or to Seller's Actual Knowledge binding on Seller which would prevent Seller from consummating
the transaction contemplated by this Agreement.

 

(c)       Except
as disclosed in Exhibit “L” attached hereto, Seller has received no written notice from any governmental agency that
the Property or the use and operation thereof violate any applicable federal, state or municipal law, statute, code, ordinance,
rule or regulation (including those relating to environmental matters), except with respect to such violations as have been fully
cured prior to the date hereof, and, to Seller’s Actual Knowledge, the Property is not in violation of any applicable federal,
state or municipal law, statute, code, ordinance, rule or regulation (including those relating to environmental matters).

 

(d)       Except
as disclosed in Exhibit “L” attached hereto, Seller has not received written notice from any governmental agency of
any condemnation, zoning, or land use proceedings relating to the Property and, to Seller’s Actual Knowledge, no condemnation,
zoning, or land use proceedings are pending or threatened (in writing) that affect the Property.

 

(e)       Except
as disclosed on Exhibit “L” attached hereto, Seller has not received written notice of any existing actions, suits,
litigation, or other proceedings that have been filed against Seller that arise out of or relates to the ownership of the Property,
and, to Seller’s Actual Knowledge, no actions, suits, litigation, or other proceedings are pending or threatened (in writing)
that arise out of or relate to Seller’s ownership of the Property.

 

    	 	13	 

     

    

  

(f)        To
Seller's Actual Knowledge, neither Seller nor any of its respective affiliates or constituents, nor any of their respective brokers
or other agents acting in any capacity in connection with the transactions contemplated by this Agreement is or will be (a) conducting
any business or engaging in any transaction or dealing with any person appearing on the U.S. Treasury Department's Office of Foreign
Assets Control ("OFAC") list of restrictions and prohibited persons ("Prohibited Person") (which

receiving of any contribution of funds, goods or services to or for the benefit of any Prohibited Person; (b) dealing in, or otherwise
engaging in any transaction relating to, any property or interests in property blocked pursuant to Executive Order No. 13224 dated
September 24, 2001, relating to "Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit,
or Support Terrorism"; or (c) engaging in or conspiring to engage in any transaction that evades or avoids, or has the purpose
of evading or avoiding, or attempting to violate, any of the prohibitions set forth in any U.S. anti-money laundering law.

 

(g)       To
Seller's Actual Knowledge, the Rent Rolls and Operating Statements for the year 2018 are true, complete, and correct.

Seller's Actual Knowledge, the aggregate amount of Cure Costs under the Leases and Contracts as of the Effective Date is $143,227.87.

the tenants and the property manager of the Real Property, and (b) the actual (and not implied, imputed, or constructive) knowledge
of the agents or employees of CBRE, Inc. acting in its capacity of or providing services to Seller as, property manager of the
Property, and not individually and without personal liability therefore. The Buyer acknowledges that it is unlikely that Marcus
P. Rogers has any extensive knowledge with respect to any specific asset of the Estate of James F. Cotter, Deceased. The Buyer
is relying on the Bankruptcy Court Sale Order and its Title Policy.

 

The representations and warranties made
by Seller in this Agreement shall not survive the recordation of the Deed. If, after the Effective Date, but before the Close of
Escrow, Seller has Actual Knowledge of any facts or changes in circumstances that would cause any of its representations and warranties
in this Agreement to be untrue at Close of Escrow, Seller shall notify Buyer in writing of such fact. In such case, or in the event
Buyer obtains information after the Due Diligence Period which would cause any of Seller's representations and warranties to be
untrue at Close of Escrow, Buyer, as its sole and exclusive remedy, shall have the right to either (i) terminate this Agreement
to the extent that the failure of any such representation or warranty to be true would have a material adverse impact on the Property
or create material liability of Buyer not contemplated in this Agreement, in which case the Deposit shall be immediately returned
to Buyer and neither party shall have any rights or obligations under this Agreement (except for Sections 4.3.1, 16.3 and 16.5
which survive termination of this Agreement), in which event Seller shall pay to Buyer an amount equal to Buyer's costs and expenses
(including reasonable attorneys' fees and expenses) incurred in connection with Buyer's due diligence investigations and negotiation
and execution of this Agreement, not to exceed Two Hundred Fifty Thousand and No/100 Dollars ($250,000.00); or (ii) to the extent
Buyer is not permitted to terminate this Agreement pursuant to clause (i) above, accept a qualification to Seller's representations
and warranties as of the Close of Escrow and complete the purchase and sale of the Property without any rights to recovery for
breach of the unqualified representation and warranty.

 

11.2     As-ls.
As of the expiration of the Due Diligence Period, Buyer will have, at its own cost and expense, made its own independent investigation
respecting the Property and all other aspects of this transaction, and shall have relied thereon and on the advice of its consultants
in entering into this Agreement, and Buyer, by proceeding with this transaction following the expiration of the Due Diligence Period,
shall be deemed to have determined that the same are satisfactory to Buyer.

Accordingly, subject to Seller's Warranties, Buyer, on behalf of itself and all of its officers, directors, shareholders, employees,
representatives and affiliated entities (collectively, the "Releasors") hereby expressly waives and relinquishes

    	 	16	 

     

    

  

THE FOREGOING WAIVERS, RELEASES AND AGREEMENTS
BY BUYER, ON BEHALF OF ITSELF AND THE RELEASORS, SHALL SURVIVE THE CLOSE OF ESCROW AND THE RECORDATION OF THE DEED AND SHALL NOT
BE DEEMED MERGED INTO THE DEED UPON ITS RECORDATION.

 

12.3     ERISA.
Buyer is not purchasing any of the Property with "plan assets" of an Employee Benefit Plan subject to Title I of the
Employee Retirement Income Security Act of 1974 (as amended from time to time, the "Act," and together with any regulation,
rule or judicial or administrative case, order, or pronouncement arising under or connected with the Act, "ERISA") or
of a plan subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"). Buyer shall take all
actions reasonably requested by Seller for the purpose of ensuring, to Seller's satisfaction, that the transactions contemplated
herein will comply with ERISA and not result in an imposition of an excise tax under Section 4975 of the Code; such actions shall
include, without limitation, the making of such further representations and warranties as Seller's counsel reasonably deems necessary
to ensure that neither this Agreement nor any of the transactions contemplated herein will violate ERISA or result in an imposition
of an excise tax under Section 4975 of the Code. In the event that this Agreement, or any transaction or other action by Seller
in connection herewith, shall be deemed to violate ERISA or result in an imposition of an excise tax under Section 4975 of the
Code, Seller may immediately terminate this Agreement (without any liability to Seller) in accordance with, and subject to the
terms and conditions of, Section 9.3 hereof as if such termination arose from a failed condition under Section 9.3
hereof.

 

		13.	DEFAULT AND DAMAGES.

 

13.1     DEFAULT
BY BUYER. BUYER AND SELLER HEREBY ACKNOWLEDGE AND AGREE THAT, IN THE EVENT THE CLOSE OF ESCROW FAILS TO OCCUR DUE TO A
BUYER DEFAULT (ALL OF THE CONDITIONS TO BUYER'S OBLIGATIONS TO CLOSE HAVING BEEN SATISFIED OR WAIVED), SELLER WILL SUFFER DAMAGES
IN AN AMOUNT WHICH WILL, DUE TO THE SPECIAL NATURE OF THE TRANSACTION CONTEMPLATED BY THIS AGREEMENT AND THE SPECIAL NATURE OF
THE NEGOTIATIONS WHICH PRECEDED THIS AGREEMENT, BE IMPRACTICAL OR EXTREMELY DIFFICULT TO ASCERTAIN. IN ADDITION, BUYER WISHES TO
HAVE A LIMITATION PLACED UPON THE POTENTIAL LIABILITY OF BUYER TO SELLER IN THE EVENT THE CLOSE OF ESCROW FAILS TO OCCUR DUE TO
A BUYER DEFAULT, AND WISHES TO INDUCE SELLER TO WAIVE OTHER REMEDIES WHICH SELLER MAY HAVE IN THE EVENT OF A BUYER DEFAULT. BUYER
AND SELLER, AFTER DUE NEGOTIATION, HEREBY ACKNOWLEDGE AND AGREE THAT THE AMOUNT OF THE DEPOSIT REPRESENTS A REASONABLE ESTIMATE
OF THE DAMAGES WHICH SELLER WILL SUSTAIN IN THE EVENT OF SUCH BUYER DEFAULT. BUYER AND SELLER HEREBY AGREE THAT SELLER MAY, IN
THE EVENT THE CLOSE OF ESCROW FAILS TO OCCUR DUE TO A BUYER DEFAULT, AS SELLER'S SOLE AND EXCLUSIVE REMEDY AS A RESULT OF BUYER'S
DEFAULT, TERMINATE THIS AGREEMENT BY WRITTEN NOTICE TO BUYER AND ESCROW HOLDER, CANCEL THE ESCROW AND RECEIVE OR RETAIN (IF SELLER
ALREADY HOLDS THE DEPOSIT) THE DEPOSIT AS LIQUIDATED DAMAGES AND ESCROW HOLDER SHALL IMMEDIATELY DELIVER (UNLESS IT HAS ALREADY
DONE SO) THE DEPOSIT TO SELLER SUCH RETENTION OF THE DEPOSIT BY SELLER IS INTENDED TO CONSTITUTE LIQUIDATED DAMAGES TO SELLER AND
SHALL NOT BE DEEMED TO CONSTITUTE A FORFEITURE OR PENALTY. NOTHING IN THIS SECTION 13.1 SHALL (A) PREVENT OR PRECLUDE ANY
RECOVERY OF ATTORNEYS' FEES OR OTHER COSTS INCURRED BY SELLER PURSUANT TO SECTION 16.5 OR (B) IMPAIR OR LIMIT THE EFFECTIVENESS
OR ENFORCEABILITY OF THE INDEMNIFICATION OBLIGATIONS OF BUYER CONTAINED IN SECTIONS 4.3.1 AND 14 HEREOF.

 

13.2     Default
by Seller. If Seller defaults in its obligations pursuant to this Agreement, Buyer's sole and exclusive remedy shall be
to elect one of the following: (a) to terminate this Agreement, in which event Buyer shall be entitled to the return by the Escrow
Holder to Buyer of the Deposit, and Seller shall pay to Buyer an amount equal to Buyer's costs and expenses (including reasonable
attorneys' fees and expenses) incurred in connection with Buyer's due diligence investigations and negotiation and execution of
this Agreement, not to exceed Two Hundred Fifty Thousand and No/100 Dollars ($250,000.00) in the aggregate, or (b) to bring a suit
in the United States Bankruptcy Court for the Western District of Texas, San Antonio Division, for specific performance provided
that any suit for specific performance must be brought as to the Property within 45 days after the Closing Date, Buyer's waiving
the right to bring suit at any later date to the extent permitted by law. This Agreement confers no present right, title or interest
in the Property to Buyer and Buyer agrees not to file a lis pendens or other similar notice against the Real Property except in
connection with, and after, the proper filing of a suit for specific performance.

 

    	 	17	 

     

    

  

		14.	BROKER'S COMMISSIONS.

 

Except for CBRE, Inc., Seller's broker
(whose commission shall be paid by Seller pursuant to a separate agreement between Seller and Seller's broker) and Price Edwards
 & Company (“Buyer's Broker”) (whose commission shall be paid by Buyer pursuant to a separate agreement
between Buyer and Buyer's Broker), neither party hereto has had any contact or dealing regarding the Real Property, or any communication
in connection with the subject matter of this transaction, through any licensed real estate broker or other person who can claim
a right to a commission or finder's fee as a procuring cause of the sale contemplated herein. In the event that any other broker
or finder perfects a claim for a commission or finder's fee, the party responsible for the contact or communication on which the
broker or finder based such claim shall indemnify, save harmless and defend the other party from said claim and all costs and expenses
(including reasonable attorneys' fees) incurred by the other party in defending against the same.

 

Seller acknowledges that prior to the commencement
of discussions with Buyer regarding the purchase of the Property, Hall, Estill, Hardwick, Gable, Golden, & Nelson, P.C. (“Hall
Estill”), a material tenant of the Property Buyer, disclosed to Seller that Hall Estill was evaluating a potential renewal
of its lease at the Property or a relocation of its office to another property (the “Hall Estill Transaction”). Seller
further acknowledges that Buyer and Buyer’s Broker have each disclosed to Seller that Buyer’s Broker has represented
and is currently representing Hall Estill with respect the Hall Estill Transaction, and Seller has no objection to the concurrent
and common engagement of, and representation by, Buyer’s Broker of Hall Estill with respect to the Hall Estill Transaction
and Buyer with respect to the transaction contemplated by this Agreement. Seller waives and forever discharges and releases any
claim of any nature now existing or hereafter arising against Buyer or its representatives, agents, and affiliates, including Price
Edwards, arising in connection with the Hall Estill Transaction or the transactions contemplated by this Agreement. Notwithstanding
the above, Buyer, on behalf of Buyer and Buyer’s Broker, acknowledges and agrees that no such lease renewal will be executed
prior to Closing without Buyer being responsible for and specifically assuming (subject to Closing) any leasing commissions or
tenant improvement costs associated with that lease renewal.

 

		15.	BANKRUPTCY MATTERS.

 

15.1     Bankruptcy
Court Filings. Within two (2) Business Days after the Effective Date, Seller will file a motion seeking expedited entry
of the Sale Procedure Order with the Bankruptcy Court. On the later to occur of (a) two (2) Business Days after Buyer’s request,
or (b) the expiration of the Due Diligence Period, Seller shall file a motion seeking entry of the Bankruptcy Court Sale Order
with the Bankruptcy Court. Seller will pursue diligently the entry of the Sale Procedure Order and the Bankruptcy Court Sale Order,
as applicable. If the Sale Procedure Order is not entered by the Bankruptcy Court prior to the date that is five (5) days prior
the expiration of the Due Diligence Period (the “Sale Procedure Order Deadline”), then Buyer shall be
entitled to (a) extend the Due Diligence Period for a period not to exceed thirty (30) days provided Buyer gives Seller prior written
notice of such extension on or before the expiration of the Due Diligence Period, in which case the Sale Procedure Order Deadline
shall be correspondingly extended, or (b) waive the requirement of the Sale Procedure Order, provided that in no event shall the
Sale Procedure Order not be delivered by the Close of Escrow. In the event that the entry of the Sale Procedure Order, Bankruptcy
Court Sale Order, or Assignment Order is appealed or a stay pending appeal is sought, Seller will oppose the appeal or the stay
pending appeal and seek the dismissal of any appeal (including a petition for certiorari, motion for rehearing, reargument, reconsideration
or revocation). Seller will consult with Buyer and provide Buyer, where possible, at least 24 hours’ notice in advance of
filing with the Bankruptcy Court or any appellate court any motion, brief, notice, proposed order, amendment, supplement or other
pleading that Seller proposes to file in the Bankruptcy Court relating to the transactions contemplated by this Agreement. Seller
will give Buyer reasonable advance notice of any hearings regarding the motions required to obtain the issuance of the Sale Procedure
Order, the Assignment Order, or the Bankruptcy Sale Order and Buyer will have the right to attend and seek to be heard at any such
hearings. Seller shall bear the sole cost and expense for all of its attorney’s fees, costs and expenses incurred for representation
of the Seller in connection with all motions relating to the Sale Procedure Order, the Assignment Order, the Bankruptcy Court Sale
Order, and any other motions or orders filed or sought by Seller in the Bankruptcy Case. Notwithstanding any of the foregoing,
should the Court decline to enter the Sale Procedure Order but instead enter the Bankruptcy Court Sale Order, then Seller shall
have complied with this paragraph and paragraph 7.1(f) above.

15.2     Sale
Procedures.

 

(a)           The
matters set forth in this Section 15.2 shall be described in the Sale Procedure Order and the motion filed in connection therewith.
Given the extraordinary marketing period that Seller has conducted, each of Buyer and Seller acknowledges and agrees that it believes
this Agreement is the highest and best offer to purchase the Property. Seller shall not initiate contact, solicit, or encourage
submission of any inquiries, proposals, or offers by any person or entity with respect to a transaction involving the direct or
indirect sale, transfer, or disposition of the Property to a purchaser or purchasers other than Buyer or effecting any other transaction
(including a Chapter 11 plan) the consummation of which would be substantially inconsistent with the transactions herein contemplated
(a “Competing Transaction”), provided that Seller is permitted to respond to any unsolicited proposals
with respect to a Competing Transaction. Seller shall provide prompt written notice to Buyer of the receipt of any unsolicited
proposal to acquire the Property or request for information regarding the Property or access to Seller’s documentation related
to the use, ownership, or occupancy of the Property. Notwithstanding anything contained herein to the contrary, Seller shall not
entertain or consider any offer to purchase the Property from any third party other than Buyer unless the offer is a Qualified
Bid (as defined in the Sale Procedure Order) which must be received by Seller no later than the Bid Deadline (as hereinafter defined).
Among other things, a Qualified Bid must contain a bona fide offer to purchase the Property on the following terms:

 

(i)        the
purchase price in the Qualified Bid is greater than the sum of (A) the Purchase Price, (B) the Expense Reimbursement, (C) the Break-Up
Fee, and (D) $100,000.

 

(ii)       the
Qualified Bid provides for a cash deposit equal to or greater than the Deposit.

 

(iii)      the
Qualified Bid must be on terms no less favorable (and no more burdensome or conditional) to Seller than the terms of this Agreement.

 

(iv)      the
Qualified Bid does not include any contingency relating to due diligence or financing, or any other material conditions precedent
to the Buyer’s obligation to close, that is not otherwise contained in this Agreement.

 

(v)       the
bidder in the Qualified Bid demonstrates that it is financially able to consummate the Competing Transaction and provides adequate
assurance of its ability to perform the obligations of the landlord under the Assumed Leases.

 

(vi)      the
Qualified Bid must expressly exclude any right to receive a break-up fee, expense reimbursement, termination fee, or any similar
form of compensation.

 

(vii)     the
Qualified Bid must provide for the purchase of all of the Property.

 

(b)           Seller
shall provide prompt written notice to Buyer of the receipt any Qualified Bid, which notice shall include in reasonable detail
sufficient information to confirm the Qualified Bid’s satisfaction of the requirements set forth above. In the event that
Seller does not receive a Qualified Bid prior to the expiration of the Due Diligence Period (the “Bid Deadline”),
Buyer and Seller shall proceed to the Close of Escrow as contemplated by this Agreement and Seller shall thereafter not be entitled
to entertain or enter into any bids for the Property, regardless of whether the bid is a Qualified Bid. If Seller does receive
a Qualified Bid prior to the Bid Deadline, Seller shall request an expedited hearing in the Bankruptcy Court to be set as soon
as the Court’s docket will accommodate such request. Seller shall request that the Court consider any higher or better offers
that may be presented to Seller and whether or not they are Qualified Bids. If the Court determines that any such offer(s) are
Qualified Bids, the Court shall conduct an auction (the “Auction”). Buyer shall be permitted to participate
in the Auction. Seller shall request the establishment of reasonable procedures for such Auction (“Auction Procedures”)
in its Sale Procedure Order which shall include, but not be limited to, the following: (i) unless otherwise ordered by the Bankruptcy
Court prior to the Auction for cause shown, any bidder (other than Buyer) that has failed to provide a Qualified Bid by the Bid
Deadline shall be disqualified from participation in the Auction; (ii) at the commencement of the Auction, Seller shall determine
based on the nature of the Qualified Bids the bid (the “Baseline Bid”) to serve as the lead bid in the
Auction, which bid will at the commencement of the Auction be announced to all bidders participating at the Auction; (iii) participating
bidders (including the Buyer to the extent Buyer so chooses) will be permitted to increase their bids and to agree to modifications
to their bids in order to make their bids more favorable to Seller, provided, subject to the following clause (iv), that each bid
shall exceed the preceding bid by $100,000.00 or a multiple thereof; (v) solely for purposes of determining the Successful Bids
(as defined below), any overbid submitted by Buyer shall be deemed to include the full amount of the Break-Up Fee and Expense Reimbursement
Payment potentially payable; and (vi) at the conclusion of the Auction, the Court shall determine, considering factors such as
the financial and contractual terms of each bid and factors affecting the speed, certainty of closing each bid and net proceeds
to the Bankruptcy Estate, the highest or otherwise best bid (the “Successful Bid”).

 

    	 	19	 

     

    

 

(c)       If
Buyer is not the proponent of the Successful Bid and a transaction is thereafter consummated with another third party purchaser
resulting in a closing of a sale of the Property, then this Agreement shall automatically terminate and Seller will pay to Buyer,
in cash, the Break-Up Fee and the Expense Reimbursement pursuant to the Sale Procedure Order. The Break-Up Fee and Expense Reimbursement
shall be paid in cash concurrently with the consummation and closing (which, in the case of a plan of reorganization or liquidation,
shall be the effectiveness) of the first Competing Transaction to occur simultaneously with or following the termination of this
Agreement and shall be paid from the first proceeds of such Competing Transaction prior to payment of any other claims, including
claims secured by the assets that are the subject of the Competing Transaction, until the Break-Up Fee and Expense Reimbursement
are paid in full. For the avoidance of doubt, nothing in the preceding sentence shall limit the Buyer’s recourse with respect
to the Break-Up Fee and Expense Reimbursement to the proceeds described therein, and the Break-Up Fee and Expense Reimbursement
will constitute, pursuant to sections 364 and 503 of the Bankruptcy Code, a superpriority administrative expense claim in Seller’s
bankruptcy estates and in any successor bankruptcy estate of any chapter 7 proceeding following conversion of any of Seller’
chapter 11 proceedings with priority over any and all administrative expense claims. Any Break-Up Fee and Expense Reimbursement
payable pursuant to this Agreement will be allowed and paid, without any further Bankruptcy Court approval or order.

 

(d)       Notwithstanding
anything to the contrary contained herein, upon timely payment of the Break-Up Fee and Expense Reimbursement to Buyer in accordance
with this Section 15.2, Seller and its respective representatives and affiliates, on the one hand, and Buyer and its respective
representatives and affiliates, on the other hand, will be deemed to have fully released and discharged each other from any liability
resulting from the termination of this Agreement and neither Seller and its respective representatives and affiliates, on the one
hand, and Buyer and its respective representatives and affiliates, on the other hand, nor any other person or entity will have
any other remedy or cause of action under or relating to this Agreement or any applicable law.

 

(e)       Seller
acknowledges that (i) the agreements contained in this Section 15.2 are an integral part of the transactions contemplated by this
Agreement, (ii) the damages resulting from termination of this Agreement under circumstances where the Break-Up Fee is payable
are uncertain and incapable of accurate calculation and therefore, the amount payable pursuant to this Section 15.2 is not a penalty
but rather constitutes liquidated damages in a reasonable amount that will compensate the Buyer for the efforts and resources expended
and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation
of the transactions contemplated hereby and (iii) without the agreements contained in this Section 15.2 the parties would not have
entered into this Agreement.

16.2       Assignment:
Binding on Successors and Assigns. Buyer shall not assign, transfer or convey its rights or obligations under this Agreement
or with respect to the Property without the prior written consent of Seller, which consent Seller may withhold in its sole, absolute
and subjective discretion; provided, however, Buyer may assign its rights under this Agreement without Seller's consent to an Affiliate
(as hereinafter defined), so long as (i) Buyer provides Seller with notice of such assignment at least ten (10) days before the
Closing Date of its intentions to assign its rights under this Agreement to the Affiliate, which notice must be accompanied by
the name of such assignee and such assignee's signature block, (ii) the Affiliate assumes, jointly and severally, in writing Buyer's
obligations hereunder and the Affiliate agrees in writing to be subject to all of the terms and conditions set forth in this Agreement,
and (iii) Buyer shall not be released from its obligations hereunder. As used in this Section 16.2, the term "Affiliate"
means (a) an entity that directly or indirectly controls, is controlled by or is under common control with the Buyer, (b) any fund
or entity sponsored by Buyer, or (c) an entity at least a majority of whose economic interest is owned by Buyer or by the direct
or indirect owners of Buyer; and the term "control" means the power to direct the management of such entity through voting
rights, ownership or contractual obligations. Any attempted assignment in violation of the provisions of this Section 16.2
shall be void and Buyer shall be deemed in default hereunder. Any permitted assignments shall not relieve the assigning party from
its liability under this Agreement. Subject to the foregoing, and except as provided to the contrary herein, the terms, covenants,
conditions and warranties contained herein and the powers granted hereby shall inure to the benefit of and bind all parties hereto
and their respective heirs, executors, administrators, successors and assigns, and all subsequent owners of the Property.

 

16.3       Work
Product. Effective upon and in the event of a termination of this Agreement for any reason other than a default by Seller,
Buyer shall assign and deliver to Seller (at no cost to Seller), and does hereby assign without the need for any further act or
instrument (at no cost to Seller), all reports, plans, studies, documents, written information and the like which has been generated
by Buyer in-house or by Buyer's third party consultants, whether prior to the Opening of Escrow or during the period of Escrow
in connection with Buyer's proposed acquisition, development, use or sale of the Real Property excluding, however, market and economic
feasibility studies (collectively, the "Work Product"). In such event, Buyer shall deliver the Work Product
which has been assigned to Seller not later than five (5) days after the date of the termination of this Agreement. The Work Product
shall be fully paid for and shall not be subject to any lien, encumbrance or claim of any kind. Buyer shall also return all materials
and information (including, without limitation, the Property Information) given to it by Seller or its consultants during Escrow,
in the same condition as delivered to Buyer. Seller acknowledges and agrees that any such delivery of Work Product is made without
representation or warranty as to the accuracy, completeness, or content thereof by Buyer. Seller releases Buyer from all claims,
demands, causes of action, judgments, losses, damages, liabilities, costs, and expenses asserted or incurred against Seller by
reason of the information contained in, or that should have been contained in, the Work Product.

Seller or Buyer, Seller and Buyer hereby agree to perform, execute and deliver, or cause to be performed, executed and delivered,
on the Closing Date or thereafter any and all such further acts, deeds and assurances as Buyer or Seller, as the case may be, may
reasonably require in order to consummate fully the transactions contemplated hereunder.

 

16.5       Attorneys'
Fees. If any legal action is brought or if an attorney is retained for the enforcement of this Agreement or any portion
thereof, or because of any alleged dispute, breach, default or misrepresentation in connection with any of the provisions of this
Agreement, the prevailing party shall be entitled to recover from the other reimbursement for the reasonable fees of attorneys
and other costs (including court costs and witness fees) incurred by it, in addition to any other relief to which it may be entitled.
The term "prevailing party" means the party obtaining substantially the relief sought, whether by compromise, settlement
or judgment.

 

16.6       Not
Applicable.

 

16.7       Entire
Agreement. Except for the Sale Procedure Order, the Bankruptcy Court Sale Order, and the Assignment Order, this Agreement
contains the entire agreement and understanding of the parties in respect to the subject matter hereof, and the parties intend
for the literal words of this Agreement to govern and for all prior negotiations, drafts, and other extrinsic communications, whether
oral or written, to have no significance or evidentiary effect. The parties further intend that neither this Agreement nor any
of its provisions may be changed, amended, discharged, waived or otherwise modified orally except only by an instrument in writing
duly executed by the party to be bound thereby. The parties hereto fully understand and acknowledge the importance of the foregoing
sentence and are aware that the law may permit subsequent oral modification of a contract notwithstanding contract language which
requires that any such modification be in writing; but Buyer and Seller fully and expressly intend that the foregoing requirements
as to a writing be strictly adhered to and strictly interpreted and enforced by any court which may be asked to decide the question.
Each party hereto acknowledges that this Agreement accurately reflects the agreements and understandings of the parties hereto
with respect to the subject matter hereof and hereby waive any claim against the other party which such party may now have or may
hereafter acquire to the effect that the actual agreements and understandings of the parties hereto with respect to the subject
matter hereof may not be accurately set forth in this Agreement.

 

16.8       Governing
Law. This Agreement shall be governed by the laws of the State of Oklahoma, and by applicable provisions of federal law,
including the United States Bankruptcy Code.

 

16.9       Counterparts.
This Agreement may be executed simultaneously in one or more counterparts, each of which shall be deemed an original but all of
which together shall constitute one and the same instrument.

 

16.10       Headings;
Construction. The various headings of this Agreement are included for convenience only and shall not affect the meaning
or interpretation of this Agreement or any provision hereof. When the context and construction so require, all words used in the
singular herein shall be deemed to have been used in the plural and the masculine shall include the feminine and the neuter and
vice versa. The use in this Agreement of the term "including" and related terms such as "include" shall in
all cases mean "without limitation." All references to "days" in this Agreement shall be construed to mean
calendar days unless otherwise expressly provided.

 

16.11       Time
of Essence. Seller and Buyer hereby acknowledge and agree that time is strictly of the essence with respect to each and
every term, condition, obligation and provision hereof and failure to perform timely any of the terms, conditions, obligations
or provisions hereof by either party shall constitute a material breach of, and non-curable (but waivable) default under this Agreement
by the parties so failing to perform.

 

16.12       Partial
Validity; Severability. If any term or provision of this Agreement or the application thereof to any person or circumstance
shall, to any extent, be held invalid or unenforceable, the remainder of this Agreement, or the application of such term or provision
to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby, and
each such term and provision of this Agreement shall be valid and be enforced to the fullest extent permitted by law.

 

    	 	22	 

     

    

  

16.13       No
Third Party Beneficiaries. This Agreement is for the sole and exclusive benefit of the parties hereto and their respective
permitted successors and assigns, and no third party is intended to, or shall have, any rights hereunder.

 

16.14       Intentionally
Omitted.

 

16.15       Joint
Product of Parties. This Agreement is the result of arms-length negotiations between Seller and Buyer and their respective
attorneys. Accordingly, neither party shall be deemed to be the author of this Agreement and this Agreement shall not be construed
against either party.

 

16.16       Calculation
of Time Periods. Unless otherwise specified, in computing any period of time described herein, the day of the act or event
after which the designated period of time begins to run is not to be included and the last day of the period so computed is to
be included at, unless such last day is not a Business Day, in which event the period shall run until the end of the next day which
is neither a Saturday, Sunday, or legal holiday. Unless otherwise expressly provided herein, the last day of any period of time
described herein shall be deemed to end at 5:00 p.m., Oklahoma City time.

 

16.17       Procedure
for Indemnity. The following provisions govern actions for indemnity under this Agreement. Promptly after receipt by an
indemnitee of notice of any claim, such indemnitee will, if a claim in respect thereof is to be made against the indemnitor, deliver
to the indemnitor written notice thereof and the indemnitor shall have the right to participate in and, if the indemnitor agrees
in writing that it will be responsible for any costs, expenses, judgments, damages, and losses incurred by the indemnitee with
respect to such claim, to assume the defense thereof, with counsel mutually satisfactory to the parties; provided, however, that
an indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnitor, if the indemnitee
reasonably believes that representation of such indemnitee by the counsel retained by the indemnitor would be inappropriate due
to actual or potential differing interests between such indemnitee and any other party represented by such counsel in such proceeding.
The failure of indemnitee to deliver written notice to the indemnitor within a reasonable time after indemnitee receives notice
of any such claim shall relieve such indemnitor of any liability to the indemnitee under this indemnity only if and to the extent
that such failure is prejudicial to its ability to defend such action, and the omission so to deliver written notice to the indemnitor
will not relieve it of any liability that it may have to any indemnitee other than under this indemnity. If an indemnitee settles
a claim without the prior written consent of the indemnitor, then the indemnitor shall be released from liability with respect
to such claim unless the indemnitor has unreasonably withheld such consent.

 

16.18       Waiver
of Jury Trial; Jurisdiction. To the extent permitted by applicable law, the parties hereby waive any right to trial by
jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. In the
event of any litigation or claims under or arising out of this Agreement, the Buyer and Seller agree to the sole and exclusive
jurisdiction of the United States Bankruptcy Court for the Western District of Texas, San Antonio Division.

 

16.19       No
Personal Liability. Notwithstanding anything stated to the contrary herein, Seller's liability under this Agreement shall
be limited to Seller's interest in the Property and neither Seller, Seller's constituent partners, Seller's asset manager, nor
Seller's directors, employees or agents shall have any personal liability hereunder.

 

16.20       Joint
and Several Liability. If Buyer is composed of more than one individual or entity, all obligations and liabilities of Buyer
under this Agreement shall be joint and several as to each of the individuals or entities who compose Buyer.

 

IN WITNESS WHEREOF,
the parties hereto have executed this Agreement the day and year first above written.
