Castle Hills Development Project

On November 30, 2012, Global Growth Trust, Inc. (“us,” “we,” “our,” or the “Company”), through an affiliate, GGT Castle Hills Holdings LLC, entered into the Limited Liability Company Agreement (the “Joint Venture Agreement”) with HRI TRG Castle Hills, LLC (the “Hunt JV Partner”), an affiliate of Hunt Realty Investments (“Hunt Realty”), and TRG Castle Hills L.P. (the “Trinsic JV Partner”), an affiliate of Trinsic Residential Group, LP, a real estate development group (“Trinsic”). Pursuant to the Joint Venture Agreement, we agreed to fund capital contributions of up to approximately $5.66 million for a 54% interest in a joint venture, GGT TRG Castle Hills TX, LLC, a Delaware limited liability company (the “Joint Venture”), the Hunt JV Partner agreed to fund capital contributions of up to approximately $3.77 million for a 36% interest in the Joint Venture, and the Trinsic JV Partner agreed to fund capital contributions of $1.05 million for the remaining 10% interest in the Joint Venture. We are not affiliated with either Hunt Realty or Trinsic. We, through our affiliate, are the managing member of the Joint Venture, but have delegated authority to manage certain of the day-to-day operations to the Trinsic JV Partner, subject to our approval of major decisions, and certain rights to remove and replace the Trinsic JV Partner.

Generally, under the terms of the Joint Venture Agreement, operating cash flow will be distributed to us, the Hunt JV Partner and the Trinsic JV Partner on a pro rata basis. Upon the occurrence of a capital event, such as a sale of substantially all of the assets of the Joint Venture, the proceeds of the capital event will be distributed to us, the Hunt JV Partner and the Trinsic JV Partner pro rata until our invested capital is returned and a minimum return on capital is achieved, and thereafter, the Trinsic JV Partner will receive a disproportionate higher share of any remaining sales proceeds, based on our having received certain minimum threshold returns. At any time 24 months after completion of the Development Project, described below, we can make an all cash offer (i) to purchase the entire interests of the Trinsic JV Partner and the Hunt JV Partner in the Joint Venture, or (ii) to sell our entire interest in the Joint Venture to the Trinsic JV Partner. The Trinsic JV Partner has a similar right to make an all cash offer to either purchase all of our interest in the Joint Venture, or to sell to us all of its and the Hunt JV Partner’s interests in the Joint Venture. In the event of any such proposal, by us or the Trinsic JV Partner, the responding party shall be obligated to either (x) accept the proposal, or (y) to elect to purchase the interests of proposing party, at a purchase price to be determined in accordance with the formula set forth in the Joint Venture Agreement.

On November 30, 2012, as contemplated by the Joint Venture Agreement, the Joint Venture acquired from Trinsic Acquisition Company, LLC, an affiliate of Trinsic, a fee simple interest in an approximately 16-acre parcel of land (the “Castle Hills Property”) located in Lewisville Texas, 25 miles outside of Dallas for a purchase price of approximately $4.42 million. The Joint Venture funded the acquisition of the Castle Hills Property and related closing costs, as well as certain expenses, fees and pre-development costs from initial capital contributions of the members. The Joint Venture will develop, construct and operate 316 residential “Class A” garden-style units on the Castle Hills Property, which will be known as “Aura Castle Hills” (the “Development Project”). The Development Project is governed by a Development Agreement between the Joint Venture and Trinsic dated November 30, 2012 (the “Development Agreement”). The total budget for the Development Project under the Development Agreement is approximately $34.91 million. The members of the Joint Venture are required to fund the balance of their capital commitments to the Joint Venture during the initial development period to fund certain development costs. Thereafter, the balance of the development and construction costs will be funded with the Construction Loan described below in Item 2.03. Trinsic will serve as the developer for the Development Project, and shall be entitled to a fee equal to approximately $1.02 million. In addition, Trinsic Residential Builders, LLC, also an affiliate of Trinsic (“Trinsic Residential Builders”), will serve as the general contractor for the Development Project under the terms of a construction agreement between the Joint Venture and Trinsic Residential Builders, dated November 30, 2012, pursuant to which it will be entitled to a fee equal to approximately $1.23 million. Commencement of construction is planned for December 2012, with completion targeted for June of 2014. After construction is completed, we anticipate the management of the Development Project will be provided by a national property management firm specializing in the on-site management of multifamily properties.

Please see the disclosure under Items 1.01 and 2.03 herein, which is incorporated by reference herein.

Castle Hills Village Financing

On November 30, 2012, the Joint Venture entered into a Construction Loan and Security Agreement with JPMorgan Chase Bank, N.A. (the “Lender”), pursuant to which development and construction costs of the Development Project will be funded by draws on an approximately $24.44 million construction loan from the Lender (the “Construction Loan”). The Construction Loan has an initial term of three years, with two additional 12-month extensions, each subject to certain conditions and the payment of a loan extension fee. During its term, the Construction Loan will bear interest, at the Joint Venture’s election, at either: (i) the floating rate which is equal to the prime rate announced per annum publicly by the Lender from time to time plus 0.10%, or (ii) the Eurodollar rate which is equal to the announced daily Reuters LIBOR rate plus 2.60%. Accrued interest is due and payable monthly in arrears. Assuming two extensions of the initial term, the estimated outstanding principal balance of the Construction Loan would be approximately $24.19 million at the end of the second extension period.

The Construction Loan Agreement and related documents contain customary affirmative, negative and financial covenants, agreements, representations, warranties, borrowing conditions, and events of default. The Construction Loan is recourse to the Joint Venture. The Construction Loan is secured by the Castle Hills Property and all improvements to be constructed thereon; and requires completion of the Development Project within two years of the closing of the Construction Loan.

We issued a press release describing the transaction covered by this report, a copy of which is attached hereto as Exhibit 99.1.
