Attention: Jubal R. Thompson, General Counsel

The undersigned subscriber (“Subscriber”) acknowledges that he/she/it has received and reviewed the Risk Disclosures and operating agreement of Comstock Investors VII, L.C., a Virginia limited liability company (the “Company”), including the exhibits thereto (the “Company Operating Agreement”), relating to the offering of Company membership interest(s) (the “Interests”) and has reviewed it in conjunction with the risk disclosures for the manager of the Company, Comstock Holding Companies, Inc. (“Comstock” or “Manager”) as contained in the latest Annual Report filed on Form 10-K as can be found online at www.sec.gov or at its investors relations homepage found at www.comstockhomes.com. Subscriber also understands that certain portions of the offering materials contain forward-looking statements within the meaning of the federal securities laws. These statements include, but are not limited to, those identified by such words as may, will, expect, project, anticipate, estimate, believe, intend, plan and other similar terminology. These forward-looking statements reflect the Company’s current expectations and assumptions regarding future events and operating and financial performance. However, actual results are subject to risks and uncertainties, which could cause actual results to differ materially from those contained in the forward-looking statements.

Subscriber understands that the Interest(s) are being offered (the “Offering”) to a small number of investors on the terms and in the manner described herein and in the Company Operating Agreement. Subscriber also understands that any promotional materials received in conjunction with the Offering are for marketing and promotional purposes only, and Subscriber understands and agrees that he/she/it cannot rely on such promotional materials to explain all terms and conditions of this Subscription Agreement or the Company Operating Agreement. Therefore, Subscriber understands that any inconsistency between the promotional materials and this Subscription Agreement or the Company Operating Agreement must be resolved in favor of this Subscription Agreement or the Company Operating Agreement, as applicable. Subscriber acknowledges that Subscriber is not entitled to rely, and has not relied, on any oral representations.

The Company reserves the right to hold a closing of the sale and purchase of Interests before it has raised the full amount solicited in the Offering and in such event, the Company Operating Agreement shall be amended to reflect the addition of additional members at a later date. No escrow agent is being appointed in connection with the Offering.
