connection with this Agreement, the Property or the Earnest Money, the prevailing party shall be
entitled to recover from the losing party all of its costs and expenses, including court costs and
reasonable attorneys’ fees.

Article 8 — Risk of Loss

8.1 Eminent Domain. In the event all or any portion of the Property, or any access to
the Property, or any interest in the Property is taken or is threatened to be taken by eminent
domain (whether or not an eminent domain proceeding is actually commenced) prior to Closing, Seller
shall immediately notify Buyer in writing (the “Eminent Domain Notice”) which shall include
a description in reasonable detail of the property or interest therein to be taken and Seller’s
good faith estimate of the cost to repair or restore any damage to or loss of the Property which
would be occasioned by the taking. In such event Buyer may, at its sole election, terminate this
Agreement by giving written notice of such election to Seller and the Title Company not later than
the earlier of (i) the last business day prior to scheduled Closing Date, provided, however, in no
event shall Buyer be required to give notice of such election sooner than five (5) business days
after receipt of the Eminent Domain Notice, and the Closing shall be adjourned, if necessary, to
accommodate such period, or (ii) the fifteenth (15th) calendar day after Buyer’s receipt of the
Eminent Domain Notice. If Buyer so elects to terminate this Agreement, the Earnest Money Deposit
shall be returned to Buyer and neither party shall have any further rights or obligations under
this Agreement. Buyer’s failure to give timely notice to terminate this Agreement as provided
above shall be deemed to be an election to proceed to close the Transaction in accordance with the
terms of this Agreement. In such latter event, Buyer shall be entitled to participate in the
taking proceeding or the negotiations regarding the taking award, and Seller shall assign to Buyer
at Closing Seller’s right, title and interest in any taking award
which remains unpaid to Seller in connection with such taking. Further in such event, Buyer
shall receive as a credit against the Purchase Price the amount of any taking award previously paid
to Seller in connection with the taking and not used in the repair or restoration of the Property
prior to Closing. As used herein a “taking” shall be deemed to include a voluntary conveyance in
lieu of a taking by eminent domain.

Article 9 — Put Options

9.1 Put Options. As used in this Article 9 the term “Put Option Property”
will mean the Land, Appurtenances, and any Site Improvements existing at the date a Put Option
hereunder is exercised. Landmark hereby grants to Buyer a put option (“Put Option One”) to
sell to Landmark the Put Option Property existing at the time Put Option One is exercised (the
“Put Option One Exercise Date”). Barton hereby grants to Buyer a put option (“Put
Option Two”) to sell to Barton the Put Option Property existing at the time Put Option Two is
exercised (the “Put Option Two Exercise Date”). Put Option Two shall be binding on Barton,
his heirs, devisees, legatees, successors, and assigns. Put Option One and Put Option Two (herein
sometimes collectively called the “Put Options” or individually a “Put Option”) are
only exercisable after the fifth (5th) anniversary of the date the Deed is recorded and on or
before the sixth (6th) anniversary of the date the Deed is recorded (“Put Option Term”).
Buyer may elect to exercise one or both Put Options. If Buyer elects to exercise both Put Options
concurrently, the Put Options shall be deemed joint and several obligations of Landmark and Barton.
Buyer may collect the Put Option Purchase Price from Landmark and/or Barton and convey the Put
Option Property to Landmark and Barton as tenants in common. Notwithstanding the foregoing,
Landmark and Barton may agree among themselves which will acquire the Put Option Property, or in
what divided or undivided interests they will acquire the Put Option Property, and how the
obligation to pay the Put Option Purchase Price will be allocated among them. Buyer agrees to
cooperate with such internal agreements but only if the Put Option Property is timely acquired for
the total Put Option Purchase Price.

9.2 Exercising Put Option(s). Buyer may exercise the Put Options during the Put
Option Term by sending written notice of Buyer’s election to exercise the Put Option(s) (the
“Put Option Exercise Notice(s)”).

9.3 Put Option Purchase Price. The purchase price for the Put Option Property (the
“Put Option Purchase Price”) shall be shall be equal to the Purchase Price together with
interest thereon from the Closing Date (of Buyer’s acquisition of the Property) until the Put
Option Exercise Date at the annual rate of Ten Percent (10%) per year, not compounded. In other
words, the Put Option Purchase Price will be determined as if Buyer had loaned Landmark and Barton
the Purchase Price on the date of Closing and Landmark and/or Barton are jointly and severally
obligated to repay the same, with annual interest at Ten Percent (10%), not compounded, on the
applicable Put Option Exercise Date. The intent of this Article 9 is for Landmark and Barton to
jointly and severally guarantee Buyer a Ten Percent (10%) return on its investment in the Property
(less closing costs to consummate the Put Option)s)) over a period ending on the Put Option
Exercise Date, but with such guarantee to expire if not exercised, on the sixth (6th) anniversary
of the date the Deed is recorded.

9.4 Other Terms of Sale Pursuant to Put Option. The purchase and sale of the Put
Option Property shall be consummated within thirty (30) days after the giving of the Put Option
Exercise Notice(s). Landmark and Barton agree to accept title to the Put Option Property pursuant
to a special warranty deed from Buyer (i.e. subject to the same title exceptions as contained in
the Deed). Landmark and Barton further agree to accept the Put Option Property in its current
physical condition, and if applicable, subject to such additional physical matters arising after
the Closing Date provided such additional matters do not materially adversely affect
the value of the Put Option Property. The closing costs relating to the consummation of the
Put Option(s) and the allocation thereof among the Buyer (as seller), and Landmark and Barton (as
buyers) shall be the same as set forth in Section 7.1; provided, however, Buyer shall not be
obligated to furnish a survey of the Put Option Property. The income and expenses of the Put
Option Property will be prorated as of the closing date of the consummation of the Put Option and
the Put Option Purchase Price will be adjusted on the same basis as set forth in Section 7.2 above.

9.5 Golsen Subordination. Golsen has represented that he has loaned $1,076,770.83 to
Barton (the “Golsen Loan”) pursuant to a promissory note dated March 2, 2011. Golsen has
agreed to subordinate his right to be repaid the Golsen Loan to Buyer’s prior right to be paid all
sums that may become due and owing pursuant to the exercise of the Put Options. Therefore, Golsen
agrees the Golsen Loan shall at all times be subordinate and inferior in right of payment to
Buyer’s right to be paid any amount becoming due under the Put Options. In furtherance of Golsen’s
subordination agreement set forth above, Golsen and Barton further agrees as follows:

(i) During the Put Option Term and any period thereafter if a Put Option has been exercised
and not full performed by Landmark and/or Barton:

(a) Golsen will not ask, demand, sue for, take or receive from Barton (or from any assumptor
or guarantor of the Golsen Loan, any nominee of any thereof, or otherwise), by set-off or in any
other manner, or retain, any payment or distribution on account of the Golsen Loan (whether
principal, interest or otherwise), nor will Golsen ask, demand or receive any security for all or
any part of the Golsen Loan;

(b) Golsen hereby directs Barton not to make, and Barton hereby agrees not to make, any
payments on the Golsen Loan until the earlier satisfaction or expiration of all Put Option
obligations by Landmark and/or Barton;

(c) Golsen will not declare all or any part of the Golsen Loan owing to Golsen due and payable
by reason of any default or any other reason, or commence, or join with any other creditor in
commencing, any proceeding against the Barton under any bankruptcy, reorganization, readjustment of
debt, suspension of payments, receivership, liquidation or insolvency law or statute now or
hereafter in effect (“Proceedings”);

(d) if the Barton makes an assignment for the benefit of creditors or any Proceedings are
commenced by or against Barton, then and in any such event and at any time thereafter, Golsen will,
upon the written request of Buyer, (1) duly and promptly take such action as may be required by
Buyer to collect the Golsen Loan for the account of Buyer (to be held by Buyer as security for the
performance of the Put Option obligations and without allowance of interest thereon) and/or to file
appropriate proofs of claim in respect of the Golsen Loan; (2) authorize and empower (and Golsen
hereby authorizes and empowers) Buyer to vote the full amount of the Golsen Loan in any Proceeding
affecting Barton and in any meeting of creditors of Barton, and (3) duly and promptly execute and
deliver to Buyer or its representatives on demand such powers of attorney, proofs of claim and
other instruments as may be requested by Buyer or its representatives in order to enable Buyer to
(A) enforce any and all claims upon or with respect to the Golsen Loan; (B) collect and receive any
and all such payments or distributions which may be payable or deliverable at any time upon or with
respect to the Golsen Loan, and (C) vote the full amount of the Golsen Loan in any Proceeding or
meeting referred to in the immediately preceding clause (2); and

 

12

 

(e) upon any distribution of the assets of Barton in connection with any dissolution, winding
up, liquidation or reorganization of Barton (whether in connection with
Proceedings, an assignment for the benefit of creditors, any other marshalling of the assets
and liabilities of Barton or otherwise), Buyer shall first be entitled to receive payment in full
of amount of any Put Option that has been exercised or otherwise the amount of any Put Option that
that could be exercised on the last day of the Put Option Term (as applicable, the “Superior
Indebtedness”), before Golsen shall be entitled to receive any payment in respect of the Golsen
Loan, and any payment or distribution of assets of Barton to which Golsen would be entitled but for
the provisions of this Agreement shall be made directly to Buyer to the extent necessary to pay the
Superior Indebtedness, without regard to whether such Superior Indebtedness is then due or remains
contingent only. Upon any such dissolution, winding up, liquidation or reorganization, any payment
or distribution of assets of Barton of any kind or character, whether in cash, property or
securities, to which Golsen would be entitled except for the provisions of this Agreement
(including any such payment or distribution which may be payable or deliverable by virtue of the
provisions of securities which are subordinated as junior in right of payment to the Golsen Loan)
shall be made by the liquidating trustee, agent or other person making such payment or distribution
(whether a trustee in bankruptcy, a receiver, a liquidating trustee or otherwise)(a “Paying
Party”), or if received by Golsen, by Golsen, directly to Buyer, to the extent necessary to pay
in full the Superior Indebtedness remaining unpaid, after giving effect to any concurrent payment
or distribution to Buyer. Golsen hereby authorizes and directs each Paying Party to pay over to
Buyer, upon demand by Buyer, all such payments or distributions without the necessity of any
inquiry as to the status or balance of the Superior Indebtedness, and without further notice to or
consent of Golsen. Golsen hereby irrevocably authorizes and empowers Buyer to demand, sue for,
collect and receive every such payment or distribution and give acquittance therefor, to execute,
sign, endorse, transfer and deliver any and all receipts and instruments, and to file claims and
take such other proceedings, all in the name of Golsen, or otherwise, as Buyer may deem necessary
or advisable for the enforcement of this Agreement, but Buyer has no obligation to do so. In
furtherance of the foregoing, but not by way of limitation thereof, in the event that Barton is
subject to any Proceeding, with the result that Barton is excused from meeting its obligations to
pay all or part of the interest otherwise accruing under the Superior Indebtedness during the
period subsequent to the commencement of any such proceeding, Golsen agrees that all or such part
of such interest, as the case may be, shall be payable out of, and to that extent diminish and be
at the expense of, reorganization dividends or distributions in respect of such Golsen Loan. Buyer
agrees to hold any Superior Indebtedness received before the exercise of any Put Option as security
for any later obligation by Landmark and/or Barton to perform a Put Option later exercised. If the
Put Option Period expires without a Put Option having been exercised, Buyer agrees promptly to pay
any monies so held directly to Golsen.

9.6 Obligations Survive Closing. The rights and obligations of the parties under this
Article 9 shall survive the Closing,

Article 10 — Intentionally Deleted

Article 11 — Default and Remedies

In the event a default occurs in the performance of any party’s obligations hereunder, the
non-defaulting party(ies) shall, as a condition of exercising its(their) remedies hereunder,
provide written notice of such default to the defaulting party. The defaulting party shall
thereafter have five (5) business days, commencing the day notice is deemed received, in which to
remedy such default. If Seller defaults hereunder with respect to its obligation to sell the
Property and fails to timely cure such default, or if Seller wrongfully refuses to close the sale
of the Property under the terms of this Agreement, Buyer shall be entitled to the remedies under
Texas law at the time of the breach, including, without limitation, specific performance and
injunctive relief (prohibitive and mandatory) and the right to recover as an element of its damages
all costs and expenses,
including, without limitation, those incurred in connection with the negotiation and drafting
of this Agreement and the preparation for the Closing, as well as its court costs and the
reasonable fees and expenses of its attorneys and expert witnesses, including such fees, costs, and
expenses incurred in connection with appellate proceedings. If Buyer defaults hereunder and fails
to timely cure such default or if Buyer wrongfully refuses to close the purchase of the Property
under the terms of this Agreement, Seller shall be entitled, as its sole remedy, to the Earnest
Money Deposit, which Seller shall be entitled to retain in full satisfaction of any liability of
Buyer hereunder. In the event of a dispute between Buyer and Seller relating to the Earnest Money
Deposit, the prevailing party shall have the right to recover all of its expenses and costs
incurred by reason of the dispute including, but not limited to, attorney’s fees, court costs, and
costs of suit preparation. Neither party shall be entitled to consequential or punitive damages in
connection with a breach hereof. If Landmark or Barton default under their obligations contained
in Article 9, or if Buyer has to take action to collect a Mandatory Refund Amount from Golsen under
Section 4.1.4, Buyer shall be entitled to the remedies under Texas law at the time of the breach,
including, without limitation, specific performance and injunctive relief (prohibitive and
mandatory) and the right to recover as an element of its damages all costs and expenses, including,
without limitation, its court costs and the reasonable fees and expenses of its attorneys and
expert witnesses, including such fees, costs, and expenses incurred in connection with appellate
proceedings.

Exhibit 10.3

FIRST AMENDMENT TO

REAL ESTATE PURCHASE CONTRACT

This First Amendment to Real Estate Purchase Contract (“Amendment”) is effective as of October
20, 2011, and is entered into by and among: SOUTH PADRE ISLAND DEVELOPMENT, LLC, a Delaware
limited liability company (herein “Seller”); PRIME FINANCIAL L.L.C., an Oklahoma limited
liability company, or its assigns (herein “Buyer”); LANDMARK LAND COMPANY, INC., a
Delaware corporation (“Landmark”); GERALD G. BARTON, an individual (“Barton”); and
JACK E. GOLSEN, an individual (“Golsen”).

WHEREAS, Seller, Buyer, Landmark, Barton and Golsen executed a Real Estate Purchase Contract
(“Contract”) on four tracts of land in Cameron County, Texas (the “Land”) associated with Seller’s
and Landmark’s (“Developer’s”) development of residential and commercial real property in Cameron
County, Texas (the “Planned Development”) of which the Land is a part; and

WHEREAS, International Bank of Commerce (“Lender”) holds liens on the Land and other real
property in the Planned Development that secure the payment of Developer’s indebtedness to Lender;
and

WHEREAS, Developer has advised Buyer that Lender and Developer are negotiating the terms of a
renewal and extension of Developer’s indebtedness owed to Lender that may: (i) increase the
portion of the Purchase Price that Developer must pay to Lender in order to obtain a release of
Lender’s liens on the Land; and (ii) impose new or modified conditions on Developer that impact
Developer’s ability to market and close on its remaining Planned Development properties in the time
and manner set forth in Developer’s short, medium and long term business plans; collectively, the
“Lender Additional Conditions”; and

WHEREAS, Buyer has advised Developer that Buyer is unwilling to proceed with the purchase of
the Land if the Lender’s Additional Conditions negatively affect Developer’s short term cash flow
or Developer’s sales projections on its remaining Planned Development properties (collectively, the
“Potential Adverse Consequences”), so Buyer and Developer, in lieu of Buyer terminating the
Contract during the Inspection Period, have agreed to amend the Contract in certain respects to
give Developer time to negotiate Lender Additional Conditions that are mutually acceptable to
Developer and Lender, and that allow Developer to show Buyer, to Buyer’s reasonable satisfaction,
that the agreed Lender Additional Conditions either do not have any Potential Adverse Consequences
that adversely affect the marketability or fair market value of the Land, or that minimize such
risks.

 

 

 

NOW THEREFORE, Seller, Buyer, Landmark, Barton and Golsen agree as follows:

1. The Inspection Period under Section 4.2 is extended until the later of (i) ___ or (ii) twenty days after the date that Buyer receives an updated
Title Commitment from the Title Company based on the information disclosed in the Survey.

2. The parties acknowledge that Buyer has provided Seller a letter dated October 20, 2011,
detailing Buyer’s Title Objections (as defined in the Contract) to title and survey matters
disclosed in the Title Commitment and the Survey, as well as additional development matters
identified during the Inspection Period, collectively, the “Buyer Issues.” In lieu of the process
set forth in Section 3.4 of the Contract, on and after the date of this Amendment, Seller and Buyer
shall seek to resolve, prior to the expiration of the Inspection Period, to Seller’s and Buyer’s
mutual satisfaction, the Buyer Issues. If there are unresolved Buyer Issues at the expiration of
the Inspection Period, the Contract will terminate, unless Buyer, in writing, prior to the
expiration of the Inspection Period, agrees to waive any outstanding Buyer Issues. If the Contract
is terminated, Seller will return the Earnest Money Deposit to Buyer within five (5) calendar days
of the termination of the Contract, Seller shall bear the cost of all title work, including the
Survey, and any survey consultation services of Pena Engineering, procured in connection with the
Contract, and thereafter Seller and Buyer shall have no further rights or obligations under the
Contract.

3. Seller acknowledges receipt of the initial $350,000 Earnest Money Deposit required of Buyer
under Section 2.1 of the Contract. The requirement for the “First Additional Earnest Money Deposit
(as defined in the Contract), and the “Second Additional Earnest Money Deposit (as defined in the
Contract) are deleted from the Contract.

4. The fourth sentence in Section 6.1 of the Contract is deleted in its entirety.

5. Except as provided in this Amendment, all other terms and conditions of the Contract remain in
full force and effect.

IN WITNESS WHEREOF, the parties have executed this Amendment on the separate signature pages
attached as a part hereof.
