EXHIBIT 10.15

REAL ESTATE ACQUISITION AGREEMENT

THIS REAL ESTATE ACQUISITION AGREEMENT the (“Agreement”) is dated the 15th day of November, 2012, by and between IBG ADRIATICA HOLDINGS, INC., hereinafter referred to as “Seller”, and HIMALAYAN ST. PAUL’S SQUARE HOLDINGS, LLC, hereinafter referred to as “Buyer”.

WITNESSETH:

For and in consideration of the mutual covenants hereinafter contained, the parties agree as follows:

1. Sale Agreement. Seller hereby agrees to sell, and Buyer hereby agrees to purchase, upon the terms hereinafter stated, the properties more particularly described on Exhibit “A” and Exhibit “B” attached hereto (collectively, the “Property”).

Seller hereby acknowledges receipt of the sum of $50.00 cash (the “Option Consideration”) from Purchaser, as consideration for execution of this Agreement by Seller. If the purchase and sale of the Property is consummated pursuant to this Agreement, the Option Consideration shall be applied toward the cash portion of the Purchase Price (as hereinafter defined) paid by Purchaser. If this Agreement is terminated pursuant to a default by Seller hereunder, the Option Consideration shall be immediately returned by Seller to Purchaser. If this Agreement is terminated for any reason other than a default by Seller hereunder, Seller shall be entitled to retain the Option Consideration.

2. Purchase Price. Subject to the adjustments and pro-rations hereinafter described, the total purchase price to be paid for the Property shall be THREE MILLION FOUR HUNDRED FIFTY TWO THOUSAND AND NO/100 DOLLARS ($3,452,000.00) as follows:

2.1 Cash Closing. The entirety of the purchase price shall be paid in cash (by wired funds or certified funds satisfactory to Title Company, as defined herein, for the purposes of making an immediate funding thereof) at closing.

3. Inspection Period and Contingency. Seller agrees to permit Buyer and its representatives for a period of five (5) days from the date hereof (the “Inspection Period”) to have

access to the Property to, at Buyer’s sole expense, perform such geological, soil tests, engineering studies and other tests as Buyer shall require. Upon completion of such inspections and tests, Buyer shall, at its sole expense, cause the Property to be restored to its previous condition, and Buyer shall indemnify and hold Seller and its agents harmless of and from all claims which may be asserted against Seller or its agents and from all damages arising from such entry. During this period, Buyer shall determine to its satisfaction whether the Property is satisfactory for the construction thereon of Buyer’s proposed construction.

In order to assist Buyer in making this determination, Seller agrees to provide to Buyer, within three (3) days from the date of this Agreement, copies of all surveys, engineering reports, development studies, soil reports, and environmental assessments in Seller’s possession, if any, which Seller has obtained for the Property; provided, however, such materials shall be provided to Buyer as a convenience only, and Seller makes no representation or warranty as to the accuracy thereof or anything contained therein. Should Buyer discover evidence of Hazardous Materials on the Property which would make the Property unsuitable for Buyer’s proposed construction on the Property, Buyer shall, prior to the expiration of the Inspection Period, deliver to Seller written notice of such discovery. Upon receipt of such written notice, Seller shall, within three (3) days from the date of the Agreement, either (i) remove the Hazardous Materials from the Property to the reasonable satisfaction of Buyer, or (ii) deliver written notice to Buyer that Seller will not remove the Hazardous Materials from the Property. In the event that either (i) Seller’s efforts to remove the Hazardous Materials are not reasonably acceptable to Buyer, or (ii) Seller, in accordance with the preceding sentence, delivers written notice to Buyer that it will not remove the Hazardous Materials from the Property, Buyer shall have the right to terminate this Agreement by, within ten (10) days from the date of this Agreement, delivering to Seller a written notice of termination. Buyer shall have no right to terminate this Agreement under this Paragraph 3 for any reason other than as set forth above. Notwithstanding anything in this Paragraph 3 to the contrary, in the event Buyer fails, for any reason, to send a written notice of termination to Seller prior to the expiration of the Inspection Period, Buyer agrees that it should be conclusively presumed that the Property is suitable for Buyer’s proposed construction, that all conditions to closing set forth in this Paragraph 3 have been satisfied, and Buyer shall have no further right to terminate this Agreement pursuant to the provisions of this Paragraph 3.

4. Title. Seller shall, within five (5) days after the date hereof, cause Reunion Title, 1700 Redbud Blvd., Suite 300, McKinney, Texas 75069 (the “Title Company”) to furnish to Buyer a commitment (hereinafter referred to as the “Commitment”) for an Owner’s Title Policy covering the Property in the form promulgated by the State Board of Insurance of the State of Texas. The Commitment covering the Property shall be in the amount of the purchase price and shall be accompanied by copies of all instruments creating any exceptions, including easements, restrictions, reservations, rights of way or other conditions, if any, affecting the Property. Seller shall cause the Title Company to issue an Owner’s Title Policy in the form Promulgated by the State Board of Insurance of the State of Texas and in the amount aforesaid, based upon the Commitment covering the Property to Buyer at closing, which Owner’s Title Policy shall be subject to the standard printed exceptions and the Permitted Exceptions, as that term is hereinafter defined. Seller and Buyer shall each pay for one-half ( ¹/₂) of the cost of said Commitment and Policy, except and excluding any and all costs associated with the deletion of the “survey exception”, which shall be paid for solely by Buyer.

4.1 Title of Record. As used herein, title shall be indefeasible, as that term is defined by the current title standards in use in the State of Texas, free and clear of all liens and encumbrances, except interest in the oil, gas and other minerals lying in and under the Property and the other Permitted Encumbrances.

4.2 Objections to Title of Record. Within three (3) days after receipt of the Commitment, Buyer shall furnish to Seller written notification of any objections to or defects in the Title of Record. Any matter reflected on the Commitment to which Buyer does not give Seller written notice of objection within said three (3) day period shall be deemed a Permitted Exception, as that term is used herein. Seller shall have the right, but not the obligation, to cure Buyer’s objections to defects in the title prior to closing. In the event such defects are not cured by such date, Buyer shall have the option to (i) terminate this Agreement by giving notice to Seller prior to closing, or (ii) waive the defects and close, in which event the matter made the basis of such objection shall constitute a Permitted Exception.

5. Plat and Survey. Within five (5) days after the date hereof, Buyer shall have ordered and received a current survey of the Property (the “Survey”) which shall have been prepared by and certified by a registered professional engineer or land surveyor, which survey shall be in a form satisfactory to the Title company such that the survey exception will be removed from the title insurance policy delivered at closing; provided, however, Buyer agrees to pay the additional title insurance premium charged by Title Company in connection therewith should Buyer elect to have the exception removed from the policy. The metes and bounds description for the Property as prepared by the surveyor in connection with the Survey shall be substituted for the description of the Property shown as Exhibit “A” attached hereto, and used in the Special Warranty Deed (the “Deed”) to be delivered at closing. Within three (3) days after receipt of the Survey, Buyer shall furnish to Seller written notice of any objections to the Survey. Any matter reflected on the Survey to which Buyer does not give Seller written notice of objection within said three (3) day period shall be deemed a Permitted Exception. Seller shall have the right, but not the obligation, to cure Buyer’s objections to the Survey prior to closing. In the event such defects are not cured by such date, Buyer shall have the option to (i) terminate this Agreement by giving notice to Seller prior to closing, or (ii) waive its survey objections and close. Buyer shall pay for the total cost of the Survey.
