Exhibit 10.101

LAND PURCHASE AGREEMENT

THIS LAND PURCHASE AGREEMENT (“Agreement”) is made this              day of                     , 2013, by and between Thos. Somerville Co., a Delaware corporation (the “Seller”), and Comstock Sixth Street, L.C., a Virginia limited liability company (“Purchaser”).

WITNESSETH:

WHEREAS, Seller is the owner of certain undeveloped real property located on 6^th Street, NE, Washington, D.C. more particularly identified on Exhibit A attached hereto and incorporated herein by reference, together with any and all improvements and fixtures thereon and all rights, privileges, easements, benefits and agreements appurtenant thereto (the “Property”); and

WHEREAS, Purchaser desires to purchase the Property in accordance with the terms and conditions hereof, and Seller desires to sell the Property in accordance with the terms and conditions hereof.

NOW, THEREFORE, in consideration of the foregoing and for TEN AND NO/100THS DOLLARS ($10.00) paid by Purchaser to Seller and for other good and valuable consideration, the receipt and sufficiency of which are hereby conclusively acknowledged, the parties agree as follows:

1. AGREEMENT OF PURCHASE AND SALE. Seller hereby agrees to sell and convey unto the Purchaser and Purchaser hereby agrees to purchase from Seller the Property at the price and upon the terms and conditions hereinafter set forth.

2. PURCHASE PRICE. Seller agrees to sell and Purchaser agrees to purchase the Property for a total purchase price of FOUR MILLION THREE HUNDRED TWENTY-SIX THOUSAND DOLLARS ($4,326,000) (the “Purchase Price”). The Purchase Price shall be paid by Purchaser to Seller in the form of cash, wire transfer or other immediately available funds at settlement hereunder.

3. DEPOSIT.

a. Within seven business days after the execution and delivery of this Agreement, Purchaser shall deliver to Stewart Title and Escrow, Inc. (the “Escrow Agent”) in the form of cash or letter of credit, SEVENTY-FIVE THOUSAND DOLLARS ($75,000) (the “Initial Deposit”). Within seven business days after the expiration of the Study Period, Purchaser shall deliver to Escrow Agent in the form of cash or letter of credit, an additional deposit of SEVENTY-FIVE THOUSAND DOLLARS ($75,000) (the “Additional Deposit”). The Initial Deposit and Additional Deposit shall be collectively referred to as the “Deposit.” The Deposit shall become nonrefundable on expiration of the Study Period (except on Seller default or failure of a condition precedent to settlement).

b. The Deposit shall be deposited by the Escrow Agent into a separate interest-bearing escrow account at a federally-insured financial institution with offices in the District of Columbia, and be invested by the Escrow Agent in a money market account, certificates of deposit or other investment(s) selected by Purchaser. If the financial condition of the financial institution in which the funds are held changes in any adverse way which prohibits the ability of the Escrow Agent to withdraw such funds in accordance with the terms of this Escrow Agreement, then the Escrow Agent may move the Deposit to another financial institution that satisfies the requirements of this paragraph 7.

c. The Deposit shall be held by the Escrow Agent until the earlier of (i) Closing (as hereinafter defined), when the Deposit shall be delivered to Seller and credited against the Purchase Price or (ii) five (5) business days after receipt by the Escrow Agent of a notice from Seller or Purchaser stating that this Agreement has been terminated, in which event the Deposit shall be delivered to Seller or returned to Purchaser, as appropriate. If all conditions precedent to the Purchaser’s obligation to purchase the Property have been satisfied and the Purchaser defaults in purchasing the Property at Closing as required by this Agreement, Escrow Agent shall pay the Deposit to the Seller and upon such payment to the Seller this Agreement shall automatically terminate and neither party shall have any further liability to the other. The Seller’s sole and exclusive remedy for the Purchaser’s default shall be to receive the Deposit as liquidated damages, in lieu of all other rights and remedies that the Seller may have against the Purchaser at law or in equity.

d. If there is a dispute between the Seller and the Purchaser concerning the Seller’s or the Purchaser’s right to receive the Deposit, Escrow Agent shall continue to hold the Deposit until the dispute is resolved by the Seller and the Purchaser or until otherwise directed by a court of competent jurisdiction. Upon termination of the escrow, all interest earned on the Deposit shall be paid to the party entitled to receive the principal.

e. Any notice sent to Escrow Agent by the Purchaser or the Seller shall simultaneously be sent to the other party and no notice to the Title Company shall be effective unless such duplicate copy is sent. Escrow Agent shall be entitled to act on any notice believed by it in good faith to be genuine and shall be released from any and all responsibility or liability with respect to the Deposit, except for its willful misconduct or gross negligence. Seller and Purchaser hereby jointly and severally indemnify the Escrow Agent and hold it harmless from any claims made against it with respect to the Deposit.

4. STUDY PERIOD. Purchaser shall have the right, in its exclusive and absolute discretion, to terminate this Agreement for any reason whatsoever by giving written notice thereof to Seller within NINETY (90) days following the Effective Date of this Agreement (the “Study Period”). As of the execution of this Agreement, Seller shall have delivered, free of charge and cost to Purchaser, all engineering, architectural or other material data regarding the Property, to the extent in Seller’s possession or control, including but not limited to generalized development plans, subdivision plans, record plat, conditions of development, and all tests, studies, reports, title reports and other materials relating to Property in Seller’s possession or control, together with a written notice to Purchaser that Seller has delivered all such material information regarding the subject Property. Seller hereby represents that the Property was the subject of a prior contract of sale pursuant to which the former contract purchaser obtained an Order of the Zoning Commission for the District of Columbia approving a Planned Unit Development on the Property in Zoning Case No. 06-26 (Feb. 12, 2007), and Purchaser agrees to review all covenants, lot division applications and other land use agreements associated with such rezoning case to the extent necessary for development of the Property for Purchaser’s intended use of the Property as a planned townhouse residential community (the “Intended Use”)..

After the Effective Date of this Agreement and until the date of settlement hereunder or termination hereof, Purchaser shall have the right, at its option and expense, to enter upon the Property at reasonable times, in a reasonable manner, and upon reasonable notice and/or cause to have performed engineering tests, studies and/or economic investigations concerning the Property. Purchaser hereby agrees to indemnify and save Seller harmless from any losses actually incurred

by Seller by virtue of Purchaser or its agents or employees entering on the Property to conduct such investigations. Purchaser further agrees to repair any physical damage caused to the Property by Purchaser or its agents or employees in connection with such tests and studies. This Paragraph 4 shall survive the termination or consummation of this Agreement.

Prior to the expiration of the Study Period hereunder, Purchaser shall obtain a title report and ALTA survey for the Property and shall deliver notice to Seller, along with a copy of the title report and ALTA survey, of any defects in title which are to be remedied. In the event of any such defects, Seller shall notify Purchaser in writing within fifteen (15) days after Seller’s receipt of Purchaser’s notice of said title defects as to whether or not Seller shall remedy same and the reasonable time period needed to do so. Seller shall have no obligation to remove any encroachments or remedy alleged title defects. If Seller elects not to remedy same, then Purchaser shall have the right to (i) elect (such election to be made in writing within ten (10) days after Seller’s notice to Purchaser) to waive such title defects and to proceed hereunder, or (ii) to terminate this Agreement whereupon the Deposit shall be returned to Purchaser, and in such event the parties shall be relieved of all further liability hereunder. From and after the Effective Date of this Agreement, Seller shall not create or permit to be created any lien, easement or any other encumbrance, affecting title to the Property, without Purchaser’s prior written consent unless same is of a nature that it will be paid and released at settlement from the proceeds of this sale. Furthermore, at or before settlement, Seller shall cause to be paid and released any and all mortgages, deeds of trust or liens secured against the portion of the Property being acquired, including but not limited to the prorated portion of all unpaid real estate taxes or assessments and utility charges through the date of the applicable settlement.

Within six (6) months from the Effective Date of this Agreement, Purchaser shall deliver notice to Seller, of any offsite easements, utility connections, or both, that are needed for its Intended Use, specifying the exact location and specifications for such easements or utility connections. Seller shall have sixty (60) days from receipt of Purchaser’s notice to determine whether it will provide such easements and/or utility connections and the time it will need to do so. If Seller, by notice to Purchaser within such sixty (60) day period, elects not to provide any one or all of such requested easements and/or utility connections or the time to obtain them is not acceptable to Purchaser, Purchaser shall have the right by notice to Seller within thirty (30) days of receipt of Seller’s notice to (i) elect to obtain the easements and/or utility connections at its own expense and to proceed under the Agreement; or (ii) to terminate this Agreement whereupon the Deposit shall be returned to Purchaser, and in such event the parties shall be relieved of all further liability hereunder. If Purchase elects to obtain the easements and/or utility connections at its own expense, Seller shall to the extent reasonably feasible and without further expense cooperate with Purchaser in obtaining any such easements or connections.

5. PRECONDITIONS OF SETTLEMENT. In addition to any other preconditions to settlement specifically provided in this Agreement, the obligation of Purchaser to proceed to settlement hereunder is subject to the satisfaction of the following conditions:

h. On the date of settlement hereunder, no suit, action, arbitration or legal, administrative or other proceeding shall be pending, or to the best of Seller’s knowledge, threatened against the Property or against Seller, with respect to the Property, or any part thereof which would materially and adversely affect the development of the Property as contemplated herein, or Seller’s ability to convey the Property; and

10. INDEMNIFICATION.

a. The Seller hereby indemnifies and agrees to defend and hold harmless the Purchaser and its successors and assigns from and against any and all claims, damages, losses and liabilities (including reasonable attorneys’ fees) which may at any time be asserted against or suffered by Purchaser from and after the Closing Date, as a result or on account of (i) any breach of any representation, warranty, covenant or agreement on the part of the Seller made herein or in any instrument or document delivered pursuant hereto; (ii) any obligation or liability relating to hazardous or toxic materials, substances or wastes accruing prior to the Closing, or (iii) any other obligation or liability (except for Permitted Exceptions) accruing prior to the Closing relating to the ownership, use, operation or maintenance of the Property that shall not have been assumed by Purchaser in accordance with the terms hereof.

12. GENERAL PROVISIONS.
