ADDENDUM

(TO COMMERCIAL CONTRACT – IMPROVED PROPERTY)

Notwithstanding anything to the contrary set forth in the Commercial Contract – Improved Property (the “Contract”) between GTC, INC., a Texas corporation (“Seller”), and HARMONY PUBLIC SCHOOLS, a Texas non-profit corporation (“Buyer”), to which this Addendum is attached, the parties hereto agree to the following provisions:

1. All defined terms used in this Addendum, unless otherwise expressly provided herein, shall have the same respective meanings as are ascribed to such defined terms in the Contract. The Contract and this Addendum shall together constitute but one and the same instrument. In the event of any conflict between the terms and provisions of this Addendum and the terms and provisions of the Contract, the terms and provisions of this Addendum shall supersede and control. All references in this Addendum to “this Contract” or “the Contract” shall mean and refer to the Contract as amended and supplemented by this Addendum.

2. Paragraph 2.B is hereby deleted and replaced with the following:

“B. Seller will convey title to (i) the Property to Seller by delivering the special warranty deed in accordance with Paragraph 10.C, and (ii) any appliances, fixtures, equipment, machinery, furniture, carpet, drapes and other personal property, if any, owned by Seller and located on or about the Property by delivering the bill of sale in accordance with Paragraph 10.D.”

3. The Earnest Money described in Paragraph 5(A) shall be fully earned by Seller and non-refundable upon the expiration of the Feasibility Period (or, if applicable, the Extended Feasibility Period), except only as expressly provided in Paragraph 6.D, Paragraph 7.B, Paragraph 15, Paragraph 16, and Paragraph 19.A.

4. Paragraph 6.D is hereby deleted and replaced with the following:

“Buyer shall have fifteen (15) days after receipt of the last of (a) the title commitment described in Paragraph 6.A(3), including copies of recorded documents evidencing the title exceptions therein (collectively, the “Title Report”), and (b) the survey described in Paragraph 6.B(1) (the “Survey”), to notify Seller in writing of any objections with respect to the Title Report and Survey (“Title Objections”). In the event Buyer provides such notice, Seller shall have five (5) days after receipt thereof (“Seller’s Response Period”) to notify Buyer whether Seller elects to cause any or all of the Title Objections disclosed therein to be removed or insured over by the Title Company. Seller’s failure to notify Buyer within Seller’s Response Period as to any Title Objection shall be deemed an election by Seller not to remove or have the Title Company insure over such Title Objection. If Seller notifies or is deemed to have notified Buyer that Seller shall not remove nor have the Title Company insure over any or all of the Title Objections, Buyer shall have until five (5) days after the expiration of Seller’s Response Period, either to terminate this Contract, or waive such Title

Objections and proceed to Closing without any abatement or reduction in the Sales Price on account of such Title Objections. If Buyer does not give such notice within said five (5) day period, Buyer shall be deemed to have elected to waive such Title Objections. If Buyer timely elects to terminate the Contract pursuant to this Paragraph 6.D, the Earnest Money, less the independent consideration under Paragraph 7.B(1), will immediately be refunded to Buyer in accordance with the terms of this Contract. The phrase “Permitted Exceptions” shall mean all exceptions to title (including printed exceptions) set forth in the Title Report and Survey other than Title Objections identified and not thereafter waived by Buyer. Notwithstanding the foregoing, in all events and regardless of whether Buyer objects to such exceptions, on or before the Closing, Seller shall discharge any voluntary lien created by Seller that is secured by any portion of the Property and discharge any lien for delinquent ad valorem taxes (“Monetary Lien”). Seller agrees any Monetary Liens do not constitute Permitted Exceptions or Permitted Encumbrances under Section 10.C. Buyer’s failure to timely object or terminate under this Paragraph 6.D is a waiver of Buyer’s right to object except that Buyer will not waive the requirements of the Title Company in Schedule C of the Title Report.”

5. The following shall be added to the end of Paragraph 7.B(1):

“Subject to the terms hereof, Buyer shall have the unilateral option to extend the Feasibility Period for one (1) additional period of thirty (30) days (the “Extended Feasibility Period”). To exercise such option, Buyer, on or prior to the expiration of the Feasibility Period, must (i) deposit with the Title Company additional earnest money in the amount of $100,000.00, which shall become part of the Earnest Money, and (ii) provide Seller written notice thereof sent in accordance with the terms of this Contract. Notwithstanding anything to the contrary in this Contract, Buyer may terminate this Contract for any reason (or no reason) whatsoever by giving written notice of termination to Seller on or before the last day of the Extended Feasibility Period. If Buyer terminates this Contract during the Extended Feasibility Period pursuant to this paragraph 7.B(1), the Earnest Money, less $50,000.00 thereof to be retained by Seller, shall immediately be refunded to Buyer in accordance with the terms of this Contract.”

6. Paragraph 7.C(1) is hereby deleted and replaced with the following:

(a) Buyer and its engineers, architects, representatives, employees and agents (the “Inspector Parties”) may access the Property for the limited purpose of inspecting the physical condition of the Property and conducting non-intrusive physical and environmental tests and inspections thereof, including without limitation a Phase I environmental assessment (provided that Buyer and its employees and agents may continue to access the Property as permitted by the Existing Lease). INSPECTOR PARTIES SHALL NOT CONDUCT OR ALLOW ANY PHYSICALLY INTRUSIVE TESTING OF, ON OR UNDER THE PROPERTY, WITHOUT FIRST OBTAINING SELLER’S WRITTEN CONSENT, WHICH CONSENT MAY BE WITHHELD IN SELLER’S SOLE AND ABSOLUTE DISCRETION, AS TO THE TIMING AND SCOPE OF THE WORK TO BE PERFORMED.

(b) Prior to entry on the Property by any Inspector Party, Buyer shall furnish (or caused to be furnished) to Seller a certificate of insurance demonstrating that Seller and any lender or other parties with insurable interest that Seller may reasonably designate are included as additional insureds (on a primary and non-contributory basis) on Buyer’s (and, if applicable, its agent’s) commercial general liability and excess umbrella liability insurance policy(ies) in compliance with the Existing Lease. Such policies shall provide, at Buyer’s or its agent’s sole cost, coverage and limits in an amount not less than the amount Buyer is required to carry under the Existing Lease. All policies shall include or be endorsed to provide a waiver of subrogation in favor of Seller and all other parties named as additional insured to such policies. Buyer agrees to maintain such coverage for so long as this Contract remains in effect.”

7. Paragraph 7.C(2) is hereby deleted.

8. Paragraph 7.C(4) is hereby deleted and replaced with the following:

The indemnity in this Paragraph 7.C(4) shall survive the Closing or any termination of this Contract.”

19. Paragraph 19 is hereby deleted in its entirety and replaced with the following:

“A. Seller Representations. The matters set forth in this Paragraph 19.A constitute representations, warranties and covenants by Seller which are now and shall, at the Closing, be true and correct:

23. Paragraph 21 is hereby deleted in its entirety.

24. Paragraph 22.E is hereby deleted in its entirety and replaced with the following:

“This Contract shall bind and inure to the benefit of Seller and Buyer and their respective successors and permitted assigns.

For the avoidance of doubt, no such assignment or assumption shall relieve Buyer or any assignee from its obligations hereunder.

25. Paragraph 24 is hereby deleted in its entirety and replaced with the following:

“The effective date of this Contract for the purpose of performance of all obligations is the date the last of Buyer and Seller executes this Contract.”

26. Survival.

Furthermore, notwithstanding anything to the contrary contained in this Contract, Seller’s liability shall not survive the Closing for more than a period of one (1) year after the Closing Date, at which time, such representations, covenants, indemnities, conditions and agreements shall terminate and be of no further effect; provided, however, any claim brought by Buyer during such one (1) year period shall survive until such claim is resolved. For the purposes of this Paragraph 26 of this Addendum, a party shall be deemed to have made a claim sufficient to preserve a party’s rights under this Contract if the party gives written notice of a claim to the other party prior to the expiration of the one (1) year survival period provided for herein; provided, however, that a party must bring suit to enforce such party’s claim no later than

ninety (90) days after the date of such notice. To the fullest extent permitted by law, the foregoing shall constitute the express intent of the parties to shorten the period of limitations for bringing claims on account of Seller’s breach of its representations, covenants, indemnities, conditions and agreements if a longer period would otherwise be permitted by applicable law.

27. Limitation on Liability. In any action brought to enforce the obligations of Seller under this Contract or any other document delivered in connection herewith, the judgment or decree shall be subject to the provisions of this Paragraph 27 of this Addendum. In all events, the liability of Seller under this Contract in the aggregate shall be enforceable against Seller only up to a maximum of $400,000 (“Maximum Liability Cap”). Further, no claim by Buyer may be made and Seller shall not be liable for any suits, claims, losses, damages, liabilities, costs and expenses (collectively, “Losses”) unless and until Buyer’s claims for such Losses exceed $25,000 in the aggregate (the “Liability Basket”), in which event Seller’s liability respecting any Losses shall be for the amount in excess of the Liability Basket, subject to the Maximum Liability Cap. Buyer acknowledges and agrees that Buyer shall have no recourse against any other property or assets of Seller or to any Seller Parties except for the Property (and the proceeds from the sale thereof), but only up to the Maximum Liability Cap, or of any of the assets or property of any of the Seller Parties for the payment or collection of any amount, judgment, judicial process, arbitral award, fee or cost or for any other obligation or claim arising out of or based upon this Contract and requiring the payment of money by Seller, except for the Property (and the proceeds from the sale thereof), but only up to the Maximum Liability Cap. The Seller Parties shall not be subject to levy, lien, execution, attachment or other enforcement procedure for the satisfaction of any of Buyer’s rights or remedies under or with respect to this Agreement, at law, in equity or otherwise, provided the foregoing shall not limit the rights of Buyer to pursue claims against the Property (and the proceeds from the sale thereof), but only up to the Maximum Liability Cap. Nothing contained in this Contract shall be deemed or construed to be an acknowledgment or agreement by Seller, or any other Seller Party that they do not have and maintain, respectively, separate existences, identities and integrity from the others, or that their separate existences, identities and integrity are impaired or should be disregarded in any manner whatsoever. The provisions of this Section are intended and shall be construed to be a limitation on liability only and shall not be deemed or be construed to create any liability or obligation of the Seller or any of the Seller Parties. The provisions of this Paragraph shall survive the Closing or termination of this Agreement.

28. Confidentiality: Seller and Buyer agree not to cause any public announcements to be made of the execution of this Contract or the Closing of this transaction, and further agree not to disclose to any party the Sales Price payable hereunder or the other terms or provisions hereof. Notwithstanding the foregoing, Seller, Buyer or title company may disclose any aspect of this transaction to any governmental agency, or any officer thereof, upon proper request or requirement therefor, where required, in accordance with applicable law, and after Closing may disclose the Closing of the transaction contemplated hereby without restriction. For the avoidance of doubt, Seller, on or after the effective date of this Contract, may cause the following filings to be made with the United States Securities and Exchange Commission as and to the extent required: (i) a Current Report on Form 8-K, and (ii) a Quarterly Report on Form 10-Q, which public filings may contain a description of the transaction and a copy of this Contract. Notwithstanding anything to the contrary contained herein, Buyer may, make disclosure of this Contract and information about the Property to its Permitted Outside Parties

(hereafter defined) as necessary to perform its obligations hereunder or to determine the feasibility of Buyer’s acquisition of the Property and as may be required under laws or regulations applicable to Buyer. In addition, the foregoing restrictions on disclosure shall not apply to information that was in Buyer’s possession prior to disclosure by Seller or is generally available to the public (other than as a result of Buyer’s wrongful disclosure thereof). “Permitted Outside Parties”, as used herein, shall mean those persons who are responsible for determining the feasibility of Buyer’s acquisition of the Property, including environmental auditors, appraisers, engineers, surveyors, title agents and consultants, and any of Buyer’s investors, officers, directors, existing or potential employees, attorneys, accountants, potential lenders, potential property managers and permitted assignees under this Contract.

THIS WAIVER IS A MATERIAL INDUCEMENT FOR SELLER TO ENTER INTO AND ACCEPT THIS CONTRACT AND THE DOCUMENTS TO BE DELIVERED BY BUYER AT CLOSING, AND SHALL SURVIVE THE CLOSING OR TERMINATION OF THIS AGREEMENT. Each party hereby authorizes and empowers the other to file this Paragraph 29 of this Addendum and this Contract with the clerk or judge of any court of competent jurisdiction as a written consent to waiver of jury trial.

30. Qualifications to Seller’s Representations. If (i) Buyer or any affiliate of Buyer has as of the effective date of this Contract, or (ii) Buyer or any affiliate of Buyer acquires from the effective date of this Contract through the Closing Date, actual knowledge or is deemed to know that Seller’s representations in this Contract or any other documents delivered by Seller in connection with the transactions contemplated by this Contract are inaccurate, untrue or incorrect in any way, then such representations and warranties shall be deemed modified to reflect such knowledge or deemed knowledge. Buyer shall be deemed to know a representation or warranty is untrue, inaccurate or incorrect if this Contract or any files, documents, materials, analyses, studies, tests, reports or other information disclosed, heretofore or hereafter made available to, whether in written or electronic form, or otherwise obtained from whatever source by Buyer contains information which is inconsistent with such representation or warranty.
