COMSTOCK HOLDING COMPANIES, INC. 

WARRANTS FOR THE PURCHASE OF SHARES OF COMMON STOCK 
  

			
	No. [            ]	 	150,000 Shares

 THIS CERTIFIES that, for value received, Comstock Holding Companies, Inc., a Delaware corporation (the
“Company”), upon the surrender of this Warrant to the Company at the address specified herein, at any time during the Exercise Period (as defined below) will upon receipt of the Exercise Price (as defined below), sell and deliver to
Comstock Development Services, LC (the “Holder”), up to the number of duly authorized, validly issued and fully paid and nonassessable shares of Class A common stock of the Company, par value $0.01 per share (the “Common
Stock”), set forth above, as appropriately adjusted pursuant to Section G. The term “Common Stock” shall mean the aforementioned common stock of the Company together with any other equity securities that may be issued by the
Company in connection therewith or in substitution therefor, as provided herein, that is not limited as to final sum or percentage in respect of the rights of the holders thereof to participate in dividends or in distribution of assets upon the
voluntary or involuntary liquidation, dissolution or winding up of the Company. The “Exercise Period” shall begin on the date six months from the date hereof and shall end on August 15, 2016. During the Exercise Period and subject to the
restrictions set forth in Section D, the Holder may purchase such number of shares of Common Stock at a purchase price per share equal to the average of the closing stock price of the 20 trading days preceding execution of this Warrant which is
shown on Schedule A hereto, and as appropriately adjusted pursuant to Section G (the “Exercise Price”).  
 The number of
shares of Common Stock to be received upon the exercise of this Warrant and the price to be paid for a share of Common Stock are subject to adjustment from time to time as hereinafter set forth. The shares of Common Stock deliverable upon such
exercise, as adjusted from time to time, are hereinafter sometimes referred to as “Warrant Shares.” 
 Section A.
Exercise of Warrant. Subject to the terms and conditions of this Warrant and applicable securities laws, the purchase right represented by this Warrant may be exercised in whole or in part, at any time or from time to time, during the
Exercise Period by presentation and surrender of this Warrant to the Company at its principal office at 1886 Metro Center Dr., 4th Floor, Reston, Virginia 20190 (or at such other address in the
United States of America as the Company may hereafter designate in writing to the Holder), with the Notice of Exercise, contained herein as Exhibit A, duly executed and accompanied by a wire transfer of immediately available funds, cash or a
certified or official bank check drawn to the order of “Comstock Holding Companies, Inc.” in the amount of the Exercise Price multiplied by the number of Warrant Shares specified in such form. The Exercise Price may also be paid in whole
or in part, by delivery of such a Notice of Exercise and shares of Common Stock owned by the Holder having an aggregate Fair Market Value (as defined below) on the last business day ending immediately prior

 
to the exercise date equal to the portion of the aggregate Exercise Price being paid in such shares. In addition, each Warrant may be exercised, pursuant to a cashless exercise by providing
irrevocable instructions to the Company, through delivery of a Notice of Exercise with an appropriate reference to this Section A as set forth below in this Section A. If this Warrant should be exercised in part only, the Company shall,
upon surrender of this Warrant, promptly execute and deliver a new Warrant evidencing the rights of the Holder to purchase the balance of the Warrant Shares purchasable hereunder. Upon receipt by the Company during the Exercise Period of this
Warrant and such Notice of Exercise, in proper form for exercise, together with proper payment of the Exercise Price, at such office, the Holder shall be deemed to be the holder of record of the number of Warrant Shares specified in such Notice of
Exercise; provided, however, that if the date of such receipt by the Company or its agent is a date on which the stock transfer books of the Company are closed, such person shall be deemed to have become the record holder of such
shares on, and such certificate shall be dated, the next succeeding business day on which the stock transfer books of the Company are open. Any new or substitute Warrant issued under this Section A, or any other provision of this Warrant, shall be
dated the date of this Warrant. Upon exercise of this Warrant, the Company shall, as soon as possible and in any event within 30 days after such exercise, cause to be issued and shall promptly deliver upon written order of the Holder, and in such
name or names as the Holder may designate, a certificate or certificates for the Warrant Shares. If the Company fails to deliver to the Holder such certificate or certificates representing the Warrant Shares pursuant to this Section A by the 30th business day after exercise hereof, then, without limiting any of its other rights or remedies, the Holder will have the right to rescind such exercise in its sole discretion. 

Notwithstanding the foregoing, in the event that at any time, the Holder elects to exercise all or any part of this Warrant, this Warrant may
also be exercised at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: 

(A) = the Fair Market Value; 

(B) = the Exercise Price of this Warrant, as adjusted (to the date of such calculation); and 

(X) = the number of Warrant Shares issuable in accordance with the terms of this Warrant for which a cashless exercise has been requested
(which shall be zero if B equals or exceeds A). 
 The “Fair Market Value” of a share of Common Stock on any day means (a) if the principal
market for the Common Stock is The Nasdaq Stock Market or any other national securities exchange, the average of the closing stock price of the 20 trading days preceding such day as reported by such exchange or market, or on a consolidated tape
reflecting transactions on such exchange or market, or (b) if the principal market for the Common Stock is not a national securities exchange or The Nasdaq Stock Market and the Common Stock is quoted on the National Association of Securities
Dealers Automated Quotations System, the average of the mean between the closing bid and the closing asked prices for the Common Stock of the 20 trading days preceding such day as quoted on such System, or (c) if the Common Stock is not quoted
on the National Association of Securities Dealers Automated Quotations System, the average of the mean between the highest bid and lowest ask prices for the Common Stock of the 20 trading days preceding such day as reported by the National Quotation
Bureau, Inc.; provided, that if none of (a), (b) or (c) above is applicable, or if no trades have been made or no quotes are available for such day, the Fair Market Value of the Common Stock shall be determined by a generally
recognized source selected by the Board of Directors of the Company reasonably acceptable to the Holder. 
 In addition to any other rights available to the
Holder, if the Company fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the Warrant Shares pursuant to an exercise of this Warrant on or before the
30th business day following such exercise, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) Common Stock to deliver in
satisfaction of a sale by the Holder of Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (1) pay in cash to the Holder the amount by which (x) the Holder’s total
purchase price (including brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection
with the exercise at issue times (B) the price at which the sell order giving rise to such purchase obligation was 

 
executed, and (2) at the option of the Holder, either reinstate the portion of this Warrant and equivalent number of Warrant Shares for which such exercise was not honored or deliver to the
Holder the number of Warrant Shares that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in
respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit the Holder’s right to pursue any other rights or remedies available to it hereunder, at law or in
equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver a certificate or certificates representing the Warrant Shares upon exercise of this Warrant
as required pursuant to the terms hereof. 
 Section B. Stock Fully Paid; Reservation of Shares. All Warrant
Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance pursuant to the terms and conditions herein, be validly issued, fully paid and nonassessable, and free and clear from all liens and all
contractual restrictions and preemptive rights with respect to the issue thereof. During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized, and reserved for the purpose of
the issue upon exercise of the rights represented by this Warrant, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant. 

Section C. Warrant Register; Transfer and Exchange. The Company will maintain a register containing the names and
addresses of each Holder of this Warrant. Any registered Holder may change such registered Holder’s address as shown on the warrant register by written notice to the Company requesting such change. Any notice or written communication required
or permitted to be given to the Holder may be delivered or given by mail to the Holder as shown on the warrant register and at the address shown on the warrant register. Until any transfer of this Warrant is made in the warrant register, the Company
may treat the registered Holder of this Warrant as the absolute owner hereof for all purposes; provided, however, that if and when this Warrant is properly assigned in blank, the Company may (but shall not be required to) treat the
bearer hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary. This Warrant may not be transferred or assigned without compliance with all applicable federal and state securities laws by the transferor and
the transferee (including the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company). Subject to the provisions of this Warrant with respect to compliance with the Act, this Warrant and all rights
hereunder may be transferred by Holder, in whole or in part, on the books of the Company maintained for such purpose at the principal office of the Company, upon surrender of this Warrant with a properly executed assignment in the form of Exhibit B
hereto (the “Assignment Form”) and upon payment of any necessary transfer tax or other governmental charge imposed upon such transfer. If this Warrant should be transferred in part only, the Company shall, upon surrender of this Warrant,
promptly execute and deliver a new Warrant evidencing the rights of the Holder thereof to purchase the balance of the Warrant Shares purchasable hereunder. 

Section D. Compliance with Securities Laws. The Holder, by acceptance hereof, agrees that, absent an effective
registration statement filed with the Securities and Exchange Commission (the “SEC”) under the Act, covering the disposition or sale of this Warrant or the Warrant Shares issued or issuable upon exercise hereof, as the case may be, and
registration or qualification under applicable state securities laws, the Holder will not sell, transfer, pledge, or hypothecate any or all such Warrants or Warrant Shares, as the case may be, unless either (a) the Company has received an
opinion of counsel, in form and substance reasonably satisfactory to the Company, to the effect that such registration is not required in connection with such disposition, or (b) the sale of such securities is made pursuant to Rule 144 under
the Act. By acceptance of this Warrant, the Holder hereby represents, warrants and covenants that (i) it is an “accredited investor” as defined in Rule 501 of Regulation D promulgated under the Act; (ii) any Warrant Shares shall
be acquired for investment only and not with a view to, or for sale in connection with, any distribution thereof; (iii) that the Holder has had such opportunity as such Holder has deemed adequate to obtain from representatives of the Company
such information as is necessary to permit the Holder to evaluate the merits and risks of its investment in the Company; (iv) that the Holder is able to bear the economic risk of holding such shares as may be acquired pursuant to the exercise
of this Warrant for an indefinite period; (v) that the Holder understands that the shares of stock acquired pursuant to the exercise of this Warrant will not be registered under the Act (unless otherwise required pursuant to exercise by the
Holder of the registration rights, if any, previously granted to the registered the Holder) and will be “restricted securities” within the meaning of Rule 144 under the Act and that the exemption from registration under Rule 144 will not
be available until the applicable holding period has been satisfied and unless a public market then exists for the stock, adequate information concerning the Company is then available to the public, and other terms and conditions of Rule 144 are
complied with; and (vi) that all stock certificates representing shares of stock issued to the Holder upon exercise of this Warrant may have affixed thereto a legend substantially in the following form: 

 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF
COUNSEL IN A FORM REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933. 
 The
legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of the Warrant Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at
DTC, if (A) such Warrant Shares are sold or transferred pursuant to Rule 144 (assuming the transferor is not an Affiliate of the Company (as defined below)), (B) such Warrant Shares are eligible for sale under Rule 144 free from any volume
or other restrictions, or (C) if such legend is not required under applicable requirements of the Act (including controlling judicial interpretations and pronouncements issued by the SEC). 

Section E. Lost, Mutilated or Missing Warrant. Upon receipt by the Company of evidence reasonably satisfactory to
it of the loss, theft, destruction or mutilation of this Warrant, and (in the case of loss, theft or destruction) of reasonably satisfactory unsecured indemnification, and upon surrender and cancellation of this Warrant, if mutilated, the Company,
at its expense, shall execute and deliver a new Warrant of like tenor and date. 
 Section F. Rights of the
Holder. Subject to applicable law, the Holder shall not, by virtue hereof, be entitled to any rights or subject to any obligation or liability of a shareholder in the Company, either at law or equity, and the rights of the Holder are limited
to those expressed in this Warrant, except to the extent the Holder has duly exercised this Warrant. 
 Section G.
Adjustments. The Exercise Price and the number of shares purchasable hereunder are subject to adjustment from time to time as follows: 

1. Subdivision and Combination. If the Company shall at any time subdivide its outstanding shares of Common Stock into
a greater number or combine into a smaller number, the number of Warrant Shares and the Exercise Price shall forthwith be proportionately decreased in the event of subdivision or increased in the event of combination. 

2. Adjustment in Number of Securities. Upon each adjustment of the Exercise Price pursuant to the provisions of this
Section G, the number of securities issuable upon the exercise of this Warrant shall be adjusted to the nearest full amount by multiplying (a) a number equal to the Exercise Price in effect immediately prior to such adjustment by
(b) the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price. 

3. Merger or Consolidation. In the event that at any time or from time to time after the date hereof, (a) the
Company shall (i) effect a reorganization, (ii) consolidate with or merge into any other person, or (iii) sell, transfer or otherwise dispose of all or substantially all of its properties or assets or (b) more than 50% of the
voting equity securities of the Company (whether issued and outstanding, newly issued, from treasury, or any combination thereof) is acquired by any other person or group under any plan or arrangement contemplating the consolidation or merger, sale,
transfer or disposition, or dissolution of the Company (each, a “Trigger Event”), the corporation or entity formed by or resulting from such consolidation or merger or the recipient of such properties, assets or equity securities shall
execute and deliver to the Holder a supplemental warrant agreement whereby the Holder shall thereafter be entitled to 

 
purchase pursuant to such supplemental warrant agreement (in lieu of the number of Warrant Shares which the Holder would have been entitled to purchase immediately prior to such Trigger Event)
the kind and number of shares of stock or other securities or property to which the Holder would have been entitled upon such Trigger Event if the Holder had exercised this Warrant in full immediately prior to such Trigger Event and acquired the
applicable number of Warrant Shares then issuable hereunder as a result of such exercise , at an aggregate purchase price equal to that which would have been payable if such number of Warrant Shares had been purchased immediately prior thereto. In
case of any such Trigger Event, lawful, adequate and appropriate provision shall be made with respect to the rights and interests thereafter of the Holder such that all the provisions of each Warrant shall thereafter be applicable, as nearly as
practicable, to such stock or other securities (“Replacement Securities”) and/or property thereafter deliverable upon the exercise of each Warrant. The supplemental warrant agreement shall contain the express assumption by such successor
corporation or entity of the due and punctual performance and observation of every provision of each Warrant to be performed and observed by the Company and of all liabilities and obligations of the Company hereunder and thereunder. Upon
consummation of any such transaction, the term “Common Stock” as used herein, shall be deemed to mean, as appropriate, such Replacement Securities and/or property, including without limitation, the definition of Warrant Shares as used
herein. 
 4. No Adjustment of Exercise Price in Certain Cases. No adjustment of the Exercise Price shall be made:

 (a) if the amount of said adjustment shall be less than one cent ($.01) per share of Common Stock issuable upon exercise
of this Warrant; provided, however, that in such case any adjustment that would otherwise be required then to be made shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which,
together with any adjustment so carried forward, shall amount to at least one cent ($.01) per share of Common Stock issuable upon exercise of this Warrant; 

(b) based upon the issuance of Common Stock to employees, consultants or directors pursuant to the Company’s 2004
Long-Term Incentive Compensation Plan (as may be amended from time to time); 
 (c) based upon the issuance of equity
securities of the Company in consideration for the acquisition (whether by merger or otherwise) by the Company or any of its subsidiaries of all or substantially all of the stock or assets of any other entity; provided that such transaction, and the
issuance of shares in connection therewith, (i) has been approved by a majority of the Board of Directors of the Company and (ii) is on commercially reasonable terms and does not involve an Affiliate (as defined in the Amended and Restated
Indenture, dated as of March 14, 2008, between the Company and Wells Fargo Bank, N.A., as may be amended from time to time); or 

(d) based upon the issuance of equity securities of the Company issued or issuable to banks or similar institutional credit
financing sources pursuant to a debt financing or similar transaction; provided that such transaction, and the issuance of shares in connection therewith, is on commercially reasonable terms and does not involve an Affiliate. 

5. Certificate as to Adjustments. Upon the occurrence of each adjustment or readjustment pursuant to this Section G,
the Company, at its own expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to each Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon
which such adjustment or readjustment is based. The Company shall, upon the written request, at any time, of any such Holder, furnish or cause to be furnished to such Holder a like certificate setting forth: (a) such adjustments and
readjustments; (b) the Exercise Price at the time in effect; and (c) the number of shares of Common Stock and the amount, if any, of other property that at the time would be received upon the exercise of this Warrant. 

 Section H. Fractional Shares. No fractional shares of Common Stock
will be issued in connection with any exercise hereunder but in lieu of such fractional shares the Company shall make a cash refund therefor equal in amount to the product of the applicable fraction multiplied by the Exercise Price paid by the
Holder for one Warrant Share upon such exercise. 
 Section I. Notices of Certain Events. In the event of: 

1. any capital reorganization or reclassification of the Common Stock (other than a subdivision or combination of the
outstanding Common Stock and other than a change in par value of the Common Stock) or of any consolidation or merger to which the Company is a party or of the conveyance or transfer of all or substantially all of the properties and assets of the
Company; 
 2. the voluntary or involuntary dissolution, liquidation or winding-up of the Company; or 

3. any other actions would require an adjustment under Section G, 

the Company will cause to be mailed to the Holder, at least ten business days before the applicable record or effective date hereinafter
specified, a notice stating (A) the date as of which the holders of Common Stock of record entitled to receive any such rights, warrants or distributions are to be determined, or (B) the date on which any such consolidation, merger,
conveyance, transfer, dissolution, liquidation or winding-up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record will be entitled to exchange their shares of Common Stock for securities or
other property, if any, deliverable upon such reorganization, reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding-up. Nothing herein shall prevent the Holder from exercising this Warrant during such 10
business day period. 
 Section J. Listing on Securities Exchanges. Subject to the restrictions on the
securities stated herein, the Company will list on The Nasdaq Stock Market and each national securities exchange on which any Common Stock may at any time be listed all shares of Common Stock from time to time issuable upon the exercise of this
Warrant, subject to official notice of issuance upon the exercise of this Warrant, and will maintain such listing so long as any other shares of its Common Stock are so listed; and the Company shall so list on The Nasdaq Stock Market and each
national securities exchange, and shall maintain such listing of, any other shares of capital stock of the Company issuable upon the exercise of this Warrant if and so long as any shares of capital stock of the same class are listed on The Nasdaq
Stock Market and such national securities exchange by the Company. Any such listing will be at the Company’s expense. 
 Section
K. Successors. All of the provisions of this Warrant by or for the benefit of the Company shall bind and inure to the benefit of its respective successors and assigns. 

Section L. Headings. The headings of sections of this Warrant have been inserted for convenience of reference
only, are not to be considered a part hereof and shall in no way modify or restrict any of the terms or provisions hereof. 
 Section
M. Amendments. Except as otherwise provided herein, the terms and provisions of this Warrant may not be modified or amended, or any provisions hereof waived, temporarily or permanently, except by written consent of the Company
and the Holder. 
 Section N. Notices. Unless otherwise provided in this Warrant, all notices, requests,
consents and other communications hereunder shall be in writing, shall be sent by first-class U.S. Mail or a nationally recognized overnight express courier postage prepaid, and shall be deemed given five business days after being sent by U.S. mail

given to each other party hereto.

contract made under the laws of the State of Delaware and for all purposes shall be construed in accordance with the laws of said State as applied to contracts made and to be performed in Delaware between Delaware residents. 

Section P. Closing of Books. The Company shall at no time close its transfer books against the transfer of any
shares issued or issuable upon the exercise of this Warrant in a manner that interferes with the timely exercise of this Warrant. 

Section Q. Severability. If any provision of this Warrant shall be held to be invalid and unenforceable, such
invalidity or unenforceability shall not affect any other provision of this Warrant.

 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 6th
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: 
 a. Purchaser, at Purchaser’s expense, shall have obtained beyond all
applicable appeals periods and from all applicable governmental authorities, approval of a Planned Unit Development, as evidenced by a Recorded PUD covenant, to allow for no less than thirty-five (35) market rate, single family residential attached
lots with minimum dimensions of 18’ wide by 38’ deep;

otherwise, required in connection with the development of the Property for Purchaser’s Intended Use which Seller has agreed to obtain pursuant to Paragraph 4 above shall have been obtained by Seller at Seller’s expense; 

 c. All utilities, in adequate capacities needed to serve the Property for Purchaser’s
Intended Use, shall be immediately available at the Property line to allow for service to be installed at Purchaser’s expense;

the representations of Seller set forth herein shall be true and accurate in all material respects and Seller shall have fully performed all of its obligations hereunder; 

g. On the date of settlement hereunder, no action of general applicability (such as the imposition of a building, water or sewer moratorium,
adequacy of public facilities scheme or allocation scheme) shall be in effect, or shall have been threatened, or publicly announced to be taken, by any applicable governmental authority relating to the Property and no such other set of circumstances
or facts of general applicability shall exist which materially and adversely affects the availability of building permits or residential use permits, or adversely affects the availability or adequacy of public facilities, sewer or water
facilities, or any other facilities or utilities necessary to serve the residential dwelling units to be constructed on the Property; 

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 
 i. Title to the Property shall be good of record and in fact, merchantable, in fee
simple and insurable at regular rates by a title insurance company selected by Purchaser subject to such other easements, rights of way, encumbrances, restrictions and other condition of title as agreed upon by Purchaser in writing and other
covenants of title that will not adversely affect the use of the Property for construction of residential dwellings;
 In the event that any
of the foregoing conditions have not been satisfied at the time set for settlement on the Property, then Purchaser, at its option and in addition to any other remedies hereunder, may either (i) terminate this Agreement by delivering written notice
thereof to Seller, whereupon the Deposit shall be returned to Purchaser and the parties hereto shall have no further rights or obligations hereunder, or (ii) waive the satisfaction of such condition and proceed to settlement hereunder, or (iii)
extend the date of the settlement in order to provide an opportunity for such condition to be satisfied, and in such event Purchaser’s obligation to settle shall remain contingent upon the satisfaction of all conditions precedent to settlement
at the time set for settlement, as extended, or (iv) pursue specific performance of this Agreement. Notwithstanding the foregoing, the time for settlement hereunder may not be extended beyond two (2) years from the Effective Date of this
Agreement, without the express written consent of Seller. 
 6. SETTLEMENT. 

a. Purchaser and Seller shall make full settlement on the Property within sixty (60) days after notice from Purchaser of the satisfaction of
the conditions precedent to closing. Closing shall be conducted at the offices of the Escrow Agent.

 b. At settlement, Seller shall (i) cause conveyance of the Property to the Purchaser by Special
Warranty Deed (the “Deed”) in proper form for recording among the land records of the jurisdiction where the Property is located, (ii) execute and deliver a DC Form FP 7/C, (iii) execute and deliver a Certificate of Non-Foreign Status By
Individual, Corporation, Partnership, Trust and/or Estate, (iv) execute and deliver all additional documents as may be requested by Purchaser, its lender or lender’s counsel, and Escrow Agent that may be reasonably required to consummate

 c. Except as otherwise provided herein, Seller and Purchaser shall each pay one-half of all escrow fees and
related costs (if any), any transfer taxes payable upon transfer of the Property to Purchaser and any “recordation tax” related to the recordation of the Deed evidencing such transfer. Seller shall pay the cost to prepare the
Deed. Purchaser shall pay all of the costs of examination of title, title insurance premiums, survey, any and all costs or recordation taxes incurred in connection with Purchaser’s financing, and all other closing costs, and each party
shall pay its own attorneys’ fees. 
 d. Rents, operating expenses, taxes (including ad valorem taxes and sanitary sewer taxes), water
and sewer rents, fuel (if any) based on last invoice price and supplier’s measurement, and similar charges or fees, and insurance assumed by the Purchaser (if any) are to be adjusted to the Closing Date. Taxes, general and special, are to
be adjusted according to the taxing authority in the District of Columbia except that assessments for improvements completed prior to the date of this Agreement, whether assessment theretofore has been levied or not, shall be paid by the Seller or
allowance made therefor at Closing. Seller shall bear all costs of terminating any service contracts not approved by Purchaser at or prior to Closing. In adjusting for uncollected rents (including operating expense pass-throughs), no
adjustment shall be made at Closing in Seller’s favor for amounts that have accrued or are unpaid as of Closing, but Purchaser shall pay Seller such accrued and unpaid amounts, as and when collected by Purchaser (less reasonable expenses of
collection thereof), it being understood that Purchaser shall not be deemed to have collected any such arrearage attributable to the period prior to Closing until such time as the tenant(s) from whom the amount is collected is current in the payment
of all amounts accruing from and after Closing. The amount of any security deposits or other amounts that are required to be returned to or applied for the benefit of tenants under the Leases as of or after the Closing Date shall be credited
against the Purchase Price (and Seller shall be entitled to retain such security deposits and other amounts). 
 7.
SELLER’S REPRESENTATIONS. Seller makes the following representations and warranties to the Purchaser: 

a. Seller has the power and authority to enter into this Agreement and perform its obligations hereunder; the performance by Seller of its
obligations hereunder does not and will not violate any law; and neither this Agreement nor the performance by Seller of its obligations hereunder violates any agreement or contract to which Seller is bound or a party. This Agreement is binding
upon and enforceable against Seller in accordance with its terms and the person signing this Agreement on behalf of Seller is authorized to do so. 

b. To the best of Seller’s knowledge, , all of the Property is vacant and free of leases, tenancies, licenses, or other rights of present
or future occupancy or use, written or verbal, for any portion of the Property, except for four short term tenancies, all of which are subject to earlier termination by Seller on notice varying from 30 to 120 days. As of the date of Settlement,
all leases on the Property shall have been terminated and all tenants shall have vacated the Property. 

 c. To the best of Seller’s knowledge, none of the Property is subject to any purchase
contract, option to purchase or right of first refusal, recorded or unrecorded, . 
 d. No Bankruptcy/Dissolution events have been done
by Seller, or against or with respect to Seller. For purposes of this Agreement, “Bankruptcy/Dissolution Events” shall be defined as (i) the commencement of a case under Title 11 of the U.S. Code, as now constituted or hereafter
amended, or under any other applicable federal or state bankruptcy law or other similar law, (ii) the employment of a trustee or receiver of any Property interest of Seller, (iii) an assignment for the benefit of creditors, (iv) an attachment,
execution or other judicial seizure of a substantial Property interest of Seller, or (v) a dissolution or liquidation of Seller. 
 e. Seller
has not received notice of violations of laws or municipal ordinances, orders or requirements noted, or issued, by any governmental department or authority having jurisdiction over or affecting the Property nor does Seller have any knowledge of any
such violations. 
 f. All bills and claims for labor performed and materials furnished to, or for the benefit of, the Property for all
periods prior to the date of settlement have been (or prior to the date of settlement thereon will be) paid in full, and on the date of settlement on the Property there shall be no mechanics’ liens or materialmen’s liens, whether or not
perfected, on or affecting any portion of the Property and if there shall be any such liens, then Seller shall obtain the release of the same on or before settlement (except that Purchaser shall pay all costs associated with liens resulting from
work for which Purchaser is obligated to pay hereunder). In connection therewith, Seller agrees, at settlement, at no additional cost to Purchaser, to execute any affidavits and/or customary indemnity agreements which may be required by
Purchaser’s title insurance company in order for Purchaser to obtain from such title insurance company an owner’s policy of title insurance covering the Property without exception for mechanics’ liens or rights of parties in
possession. 
 g. To Seller’s best information, knowledge and belief, there is no pending or threatened condemnation or similar
proceeding affecting the Property or any part thereof. 
 h. To the best of Seller’s knowledge, there are no legal actions, suits,
zoning or rezoning actions, or other legal or administrative proceedings pending or threatened against Seller or the Property and Seller is not aware of any facts which might result in any such action, suit or other proceedings; and to the best of
Seller’s knowledge there is no action, suit, proceedings or claim affecting Seller or the Property relating to or arising out of, the ownership, operation, use or occupancy of the Property pending in a court of competent jurisdiction or before
any federal, state, county or municipal department, commission, board, bureau, agency or other governmental instrumentality nor, to the best knowledge of Seller, has any such action, suit, proceeding or claim been threatened or asserted. 

i. During the period of Seller’s ownership of the Property, and to Seller’s actual knowledge, neither the Property nor any portion
thereof has been used for landfill, dumping or other waste disposal activities or operations; storage of raw materials, products or wastes of toxic or hazardous nature; and to Seller’s actual knowledge, no such hazardous materials or raw
materials of a toxic or hazardous nature presently exist on the Property, except as disclosed and or described in the following reports, copies of which Seller shall deliver to Purchaser, as provided in Paragraph 4 of this Agreement: 1) Phase I
Environmental Assessment for 6th St. N.E. prepared by ECS for Rocky Gorge Communities dated August 25, 2004 and 2) “Report of Subsurface Exploration and Geotechnicial Engineering
Analyses” prepared for Emerson Park Phase II N.E. Washington DC for Rocky Gorge Communities dated August 24, 2004. As used herein, all references to hazardous materials and raw materials, products or wastes of a toxic or hazardous nature
shall mean and refer to hazardous waste as that term is defined in the Resource Conservation 

 
and Recovery Act of 1976 (42 U.S.C. Section 6901, et. seq.) the Comprehensive Environmental Response Compensation and Liability Act of 1980 (42 U.S.C. Section 9601 et.
seq.), or under any other federal, state or local law, ordinance, statute, rule or regulation, including (without limitation) any asbestos or asbestos-related products and any oils or pesticides. Notwithstanding anything contained herein
to the contrary, Seller agrees to indemnify, defend and hold Purchaser harmless from and against any and all costs, expenses, liabilities and causes of action which may be incurred by Purchaser or asserted against Purchaser (including, without
limitation, clean-up costs, court costs, reasonable attorneys’ fees and claims and fines imposed by any governmental agencies or third parties) as a result of the breach of this representation. 

j. There shall be in existence as of the date of settlement no contracts, agreements, or other understandings with respect to the Property, or
relating to the ownership, development or operation thereof which shall survive settlement hereunder, other than matters recorded among the land records at the time of Purchaser’s title search. 

k. In the event Purchaser is required to prepare consolidated financial statements that include financial information regarding the Property in
connection with Purchaser’s regular reporting requirements, the Seller agrees to provide such information as reasonably requested by Purchaser. 

8. PURCHASER’S DEFAULT; SELLER’S
REMEDY. In the event that Seller performs all of its obligations hereunder and Purchaser fails to meet any of its obligations under the Agreement or to complete settlement
hereunder or post the Deposit as required herein, and Purchaser fails to cure such default within twenty-one (21) days of notice from Seller, then Seller shall be entitled to terminate this Agreement by delivery of written notice to Purchaser, and
thereupon the parties hereto shall have no further rights or obligations hereunder, and Seller shall receive the amount of the Deposit posted, if any, from the Escrow Agent as full liquidated damages and as its sole remedy, in lieu of any other
claims or causes of action which may be available to Seller at law or in equity by reason of such default hereunder by Purchaser, provided, however, that the Purchaser shall immediately deliver or cause to be assigned, transferred and delivered to
Seller, to the extent assignable, owned by Purchaser, or in Purchaser’s control, any Property studies, tests, engineering reports, or PUD related documents, plats, site plans and lot applications (the “Purchaser’s Study
Materials”) The Seller and the Purchaser agree that: (i) the Seller’s damages resulting from the Purchaser’s default are difficult, if not impossible, to determine; (ii) it would be impracticable and extremely difficult to
fix the actual damages suffered by the Seller as a result of the Purchaser’s failure to complete the purchase of the Property pursuant to this Agreement; and (iii) the Deposit is a fair estimate of those damages which has been agreed to in an
effort to cause the amount of said damages to be certain. In no event and under no circumstance shall Seller be entitled to receive more than the Deposit as damages for Purchaser’s default, except that Purchaser shall remain liable to
Seller for delivery of the Purchaser’s Study Materials and for any indemnification and restoration expenses due and payable to Seller under Paragraph 4 of this Agreement. 

9. SELLER’S DEFAULT; PURCHASER’S
REMEDY. In the event that Seller fails to settle on the Property pursuant to the terms hereof or otherwise breaches the terms hereof and Seller fails to cure such default within
twenty-one (21) days of notice from Purchaser, then Purchaser may, in its sole discretion (i) terminate this Agreement and receive the refund of the Deposit whereupon the parties hereto shall have no further rights or obligations hereunder, or (ii)
be entitled to enforce any and all remedies available to Purchaser, at law or in equity, provided that in an action for damages, Seller’s liability shall be limited to Purchaser’s out-of-pocket expenses for engineering, planning, title,
financing and legal expenses, not to exceed One Hundred Fifty Thousand Dollars ($150,000). 

 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. 
 b. The Purchaser hereby indemnifies and agrees to defend and hold harmless the Seller 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 the Seller 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 Purchaser made herein or in any instrument or document delivered pursuant hereto, or (ii) any obligation or liability accruing after the
Closing relating to the ownership, use, operation or maintenance of the Property. 
 c. These indemnities shall survive for a period of
twelve (12) months from the Closing Date, during which time notice must be given to the indemnitor of a specific claim. 

11. ASSIGNMENT OF ENGINEERING
DATA. Upon settlement hereunder, Seller hereby transfers and assigns, at no cost or expense to Purchaser, to the extent assignable, all of Seller’s
right, title and interest in and to any and all engineering data, plans, plats, site plans, governmental approvals, any other information and approvals obtained by Seller or within Seller’s possession or control relating to the Property
(hereinafter the “Engineering Data”). To the extent that any of the Engineering Data is not assignable, Seller shall take the necessary steps to authorize where appropriate the engineer/architect to allow Purchaser to use the
Engineering Data in connection with the development of the Property provided Seller shall assume or bear no costs to such engineer or architect for doing so. Seller makes no representation as to whether the engineer /architect retained by the
prior contract purchaser of the Property will allow Purchaser to use or rely upon any of the engineering or architectural work product, copies of which Seller has or will make available to Purchaser. As part of Purchaser’s due diligence,
Purchaser should confirm with such engineer/architect its ability to use such materials and at what fee or cost if any. Seller shall be responsible for payment of all sums owed third parties for work performed at Seller’s direction
regarding the Engineering Data, if any such work has been done. Each party shall timely mail or fax copies to the other party of all correspondence delivered to or received from governmental authorities and each party shall notify the other
party in advance of any meetings with governmental authorities and the other party shall be given the opportunity to attend such meetings. 

 12. GENERAL PROVISIONS. 

a. Broker. Other than Dianne Haskett from Washington DC Associates, PLLC, who shall be paid pursuant to a separate agreement by Seller,
Purchaser and Seller warrant that they have not dealt with any Broker in the transaction contemplated hereby. Any other fees and commissions of any broker, finder, financial advisor or other person acting in a capacity that would entitle such
person to a fee or commission in connection with the sale of the Property shall be Seller’s responsibility. Seller and Purchaser each agree to indemnify and hold harmless the other party from any claim for commission by any broker or agent
claiming any such commission for or through either Seller or Purchaser other than referenced herein. 
 b. Applicable Law. The
provisions of this Agreement and the application thereof shall be governed by the laws of the District of Columbia, without regard to principles of conflicts of laws. 

c. Survival. The provisions of this Agreement shall not be merged into the execution and delivery of the deed and shall survive such
execution and delivery. 
 d. Computation of Time. In the event that any period of time provided for under this Agreement expires, or
falls upon, a Saturday, Sunday or legal holiday, then said period of time will be deemed to be extended to the immediately following business day. No amendment, modification, or waiver under this Agreement shall be effective unless in writing
and signed by both parties. Time shall be of the essence for all purposes under this Agreement. 
 e. Entire Agreement. This
Agreement constitutes the entire agreement by and between the parties. No amendment, modification, or waiver under this Agreement shall be effective unless in writing and signed by both parties.

f. Notices. Unless otherwise agreed to by the parties any and all notices required hereunder shall be sent to the parties by hand delivery
or overnight delivery service or by certified or registered mail, return receipt requested, (or by electronic mail transmission when followed by delivery of the original) at the following addresses.

party to such Agreement. 
 h. Assignment. The parties to this Agreement mutually agree that the benefits hereunder are not assignable by
either party without prior, written consent, except that Purchaser shall be entitled to assign this Agreement to an affiliate with prior notice only, but shall be binding upon them and each of their respective successors and assigns. 

i. Rule against Perpetuities. To avoid the rule against perpetuities, in no event shall the last settlement hereunder shall take place later

 j. Counterparts. This Agreement may be executed in counterparts, each of which shall

k. Casualty. If all or any material part of the Property, or the improvements or vegetation thereon are destroyed or damaged (normal wear
and tear excepted) prior to settlement, Seller shall give notice to Purchaser of such damage or destruction and of Seller’s insurance coverage. Purchaser shall have a reasonable time (not to exceed thirty (30) days) in which to elect to
either (i) terminate this Agreement in which case the Escrow Agent shall immediately refund the Deposit to Purchaser and this Agreement will be null and void or (ii) to proceed to settlement hereunder, in which case the Purchase Price shall not be
reduced but Seller shall assign to Purchaser any and all of Seller’s right to insurance proceeds payable to Seller. Seller agrees until settlement to maintain the improvements and vegetation in their existing condition, normal wear and
tear excepted, and to preserve all existing insurance on the improvements.

12. LIKE KIND EXCHANGE. Purchaser acknowledges that Seller has
indicated that Seller may wish, at its sole cost and expense, to structure this transaction in such a manner so as to effectuate a simultaneous or deferred like-kind exchange (“Exchange”) pursuant to the applicable provisions of Section
1031 of the Internal Revenue Code, as amended. Accordingly and without any representation by Purchaser that such an Exchange is possible or permissible, Purchaser agrees that Seller shall have the right to assign its rights under this Agreement
to a third party for the purpose of effectuating such an Exchange; provided, however, that (i) the Settlement pursuant to this Agreement shall not be delayed by reason of such exchange, (ii) Purchaser shall not be required to incur any additional
cost or expense as a result of such Exchange, including the cost of reasonable attorney’s fees incurred by Purchaser for review of documents prepared by Seller for Purchaser’s execution to effectuate the Exchange, which reasonable costs
shall be reimbursed to Purchaser by Seller at Settlement, (iii) Purchaser shall not be required to acquire title to any real property other than the Property, (iv) Seller’s ability to consummate such an Exchange shall not be a condition to the
obligations of Seller or Purchaser under this Agreement, and (v) Seller’s obligation to cooperate with Purchaser shall not be impacted by any such assignment.

 REINSTATEMENT AND SECOND AMENDMENT TO 

LAND PURCHASE AGREEMENT 

(Sixth and Buchanan Streets N.E., DC) 

THIS REINSTATEMENT AND SECOND AMENDMENT TO LAND PURCHASE AGREEMENT (the “Reinstatement and Second Amendment”) is entered into as of
the day of 2014, being the latest date set forth beneath a signature at the end of this Reinstatement and Second Amendment, by and between Comstock Sixth Street, L.C., a Virginia limited liability company (“Purchaser”) and Thos.
Somerville Co. a Delaware corporation (“Seller”). 
 RECITALS: 

R-1 Comstock Sixth Street, L.C. (“Comstock”) as Purchaser and Thos. Somerville 

Co. (“TSCO”) as Seller entered into a Land Purchase Agreement effective December 23, 2013, as amended by a First Amendment dated
March 24, 2014, (the “Contract”) for the purchase and sale of approximately 4E acres of land located in Washington, D.C., near the intersection of Sixth and Buchanan Streets, N.E,, as more particularly described in the Contract and Exhibit
A thereto and defined therein as the “Property.” 
 R-2 Subsequent to the Effective Date of the Contract, the
parties agreed, per the First 
 Amendment to the Contract, to extend the Study Period under the Contract for an additional thirty (30) days
until April 22, 2014. On April 22, 2013, Comstock delivered a notice to TSCO of its election to terminate the Contract. The parties, however, have continued to discuss the purchase and sale of the Property, and now desire to reinstate the Contract,
based on certain mutually agreed upon modifications as set forth in this Reinstatement and Second Amendment. 
 NOW, THEREFORE, in
consideration of the mutual covenants of Seller and Purchaser and for other good and valuable consideration, the receipt and legal sufficiency of which the parties acknowledge, Seller and Purchaser hereby agree as follows: 

 

	 	1.	Each capitalized term used in this Reinstatement and Second Amendment and not defined herein will have the definition provided for it in the Contract. 

 

	 	2.	The Contract is hereby reinstated. The parties, by signing below, acknowledge and affirm their intent to be bound thereby, subject to the provisions of such Contract as expressly modified by this Reinstatement and
Second Amendment. 

  

	 	3.	Paragraph 2 of the Contract is modified hereby to change the Purchase Price from, $4,326,000 to $4,000,000. This Purchase Price shall be subject to increase, however, at the rate of $100,000 for each market rate
residential unit over and above thirty-three (33) market rate units for which Purchaser achieves Planned Unit Development approval. See Paragraph 5 below. 

  

	 	4.	Seller agrees to reimburse Purchaser for one-half the cost of the Phase II environmental site assessment investigation costs incurred by Purchaser 

should Purchaser elect not to proceed to Closing based solely upon the results of the Phase II site assessment
investigation, which Phase II assessment Purchaser has agreed to obtain within the Study Period as extended by Paragraph 9 below, The costs of such Phase 11 assessment, to be split between Purchaser and Seller, shall not exceed $17,700. If the
Purchaser proceeds to Closing, Purchaser shall bear the entire costs of the Phase II assessment, 

	 	5.	Paragraph 5.a. of the Contract, one of the “Preconditions to Settlement,” is amended to provide that Purchaser shall have achieved approval of a Planned Unit Development for no less than thirty-three (33)
market rate units and four (4) “affordable” dwelling units. For each market rate unit over 33, the Purchase Price will increase by $100,000. 

  

	 	6.	Paragraph 5 of the Contract is amended to add as an additional “Precondition to Settlement,” the following subparagraph “5.j.”, as a new precondition: 

“5.j. Purchaser, at Purchaser’s expense, shall have obtained the necessary governmental permit allowing it to
proceed with sediment, erosion control and grading on the Property.” 
  

	 	7.	Paragraph 6,a of the Contract is amended to provide that, notwithstanding any other provisions of the Contract as amended, Closing under the Contract shall occur on or before December 23, 2015, time being of the
essence to Seller. However, in the event all of the “Preconditions to Settlement” have not been satisfied by the December 23, 2015 date, Purchaser shall have the right to extend the Closing for two (2) periods of three (3) months each
by paying to Seller a non-refundable “Extension Fee” in the amount of Fifty thousand and no/100 dollars ($50,000.00) for each of the two extensions of the Closing. 

 

	 	8.	Seller agrees that it will grant a standard easement of record for existing natural gas and water lines to public authorities, if Purchaser reasonably requests that it do so within the Study Period as extended hereby.

  

	 	9.	The Study Period, as provided in Paragraph 4 of the Contract, is hereby extended until 5:00 p.m. EDT, Friday, June 6, 2014, for the singular purpose of allowing time for Purchaser to complete the Phase II
environmental assessment. Purchaser represents and warrants that Purchaser has completed its title report and ALTA survey (or had the opportunity to conduct an ALTA survey), and that Purchaser has accepted title to Property, waiving any obligations
or title defects. 

  

	 	10.	Seller informs Purchaser, and Purchaser acknowledges receipt of this information, that to best of Seller’s knowledge, there was never an escrow established in the amount of $200,000 (or any other amount) nor any
geotechnical report done on the section of retaining wall constructed at an increased height of approximately 16 feet on the rear portions of some of the bordering residential lots fronting on 7th Street N.E. 

	 	11.	It is the intention of Purchaser and Seller that all questions with respect to the construction of this Reinstatement and Second Amendment, and the rights or liabilities of the parties hereunder, shall be determined in
accordance with the laws of the District of Columbia, without regard to conflicts of laws principles. 

  

	 	12.	Purchaser and Seller ratify the Contract as modified here. 

  

	 	13.	This Reinstatement and Second Amendment may be executed in counterparts, which, when taken together, shall constitute one original. 

IN WITNESS WHEREOF, the parties hereto have signed, sealed and delivered this Reinstatement and Second Amendment.

Preconditions of Settlement in Paragraph 5 of the Agreement have not been completed by February 24, 2016, on the terms set out in Paragraph 7 of the Second Amendment. However, if at anytime after December 23, 2015, Purchaser elects to terminate
the Agreement under the terms and condition of the Agreement, Purchaser shall pay to Seller the first of the two Extension Fees of $50,000.00 as provided for in the Reinstatement and Second Amendment to Land Purchase Agreement except in the case an
