At the request of the Partnership, the Grantee shall execute the Partnership Agreement or a joinder or counterpart signature page thereto. The Grantee acknowledges that the Partnership may from time to time issue or cancel (or otherwise modify) LTIP Units in accordance with the terms of the Partnership Agreement. The Class 1 LTIP Units shall have the rights, voting powers, restrictions, limitations as to distributions, qualifications and terms and conditions of redemption and conversion set forth herein, in the Plan and in the Partnership Agreement. Capitalized terms used herein and not otherwise defined shall have the meanings assigned such terms in the Plan and/or the Partnership Agreement, as applicable.

Subject to Section 3 below, unless the vesting under this Agreement is accelerated in accordance with Article 14 of the Plan, 100% of the Class 1 LTIP Units subject to this Agreement shall vest and cease to be subject to the restrictions set forth in Section 3 on the first anniversary of the Vesting Commencement Date set forth above.

3.Restrictions.

Without the consent of the Committee (which it may give or withhold in its sole discretion), Restricted Units may not be sold, transferred, exchanged, redeemed, assigned, pledged, hypothecated or otherwise encumbered (collectively, “Transferred”). If the Grantee’s service with UDR, Inc.

The restrictions imposed under this Section 3 shall apply to all securities issued with respect to Restricted Units hereunder in connection with any merger, reorganization, consolidation, re-capitalization, stock dividend, unit distribution or other change in corporate structure affecting the common stock of the Company or the Partnership Units of the Partnership.

(b) On the date specified by the Committee or as otherwise established in the Plan in the event of an acceleration of vesting under Article 14 of the Plan (including, without limitation, upon retirement or the occurrence of a Change of Control, as defined in the Plan).

5.Delivery of Units. The Class 1 LTIP Units will be registered in the name of the Grantee as Restricted Units and may be held by the Company or the Partnership prior to the lapse of the restrictions thereon as provided in Section 2 or 4 hereof (the “Restricted Period”). Any certificate for Class 1 LTIP Units issued during the Restricted Period shall be registered in the name of the Grantee and shall bear a legend in substantially the following form:

In addition, if requested, the Grantee shall deposit with the Company or the Partnership, a stock/unit power, or powers, executed in blank and sufficient to re-convey the Restricted Units to the Company or the Partnership upon termination of the Grantee’s service during the Restricted Period, in accordance with the provisions of this Agreement.

Any permitted transferee of the Class 1 LTIP Units shall take such Class 1 LTIP Units subject to the terms of the Plan, this Agreement, and the Partnership Agreement. Any such permitted transferee must, upon the request of the Partnership, agree to be bound by the Plan, the Partnership Agreement, and this Agreement, and shall execute the same on request, and must agree to such other waivers, limitations, and restrictions as the Partnership or the Company may reasonably require. Any Transfer of the Class 1 LTIP Units which is not made in compliance with the Plan, the Partnership Agreement and this Agreement shall be null and void and of no effect. Notwithstanding any other provision of this Agreement, without the consent of the Committee (which it may give or withhold in its sole discretion), the Grantee shall not convert the Class 1 LTIP Units into Partnership Common Units, or Transfer the Class 1 LTIP Units (whether vested or unvested), including by means of a redemption of such Class 1 LTIP Units by the Partnership, until the earlier of (i) the occurrence of, and in connection with, a Change of Control (or such earlier time as is necessary in order for the Grantee to participate in such Change of Control transaction with respect to the Class 1 LTIP Units and receive the consideration payable with respect thereto in connection with such Change of Control) and (ii) the expiration of the two (2) year period following the Date of Grant set forth above, other than by will or the laws of descent and distribution.

8.Capital Account. The Grantee shall make no contribution of capital to the Partnership in connection with the issuance of the Class 1 LTIP Units and, as a result, the Grantee’s Capital Account balance in the Partnership immediately after his or her receipt of the Class 1 LTIP Units shall be equal to zero, unless the Grantee was a Partner in the Partnership prior to such issuance, in which case the Grantee’s Capital Account balance shall not be increased as a result of his or her receipt of the Class 1 LTIP Units.

9.Stop Transfer Notices. In order to ensure compliance with the restrictions on transfer set forth in this Agreement, the Plan or the Partnership Agreement, the Company and the Partnership may issue appropriate “stop transfer” instructions to its transfer agent, if any, and, if the Company or the Partnership transfers its own securities, it may make appropriate notations to the same effect in its own records.

10.Refusal to Transfer. The Partnership shall not be required (a) to transfer on its books any Restricted Units that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (b) to treat as owner of such Restricted Units or to accord the right to vote or make distributions to any purchaser or other transferee to whom such Restricted Units shall have been so transferred.

11.Restrictions on Public Sale by the Grantee. To the extent not inconsistent with applicable law, the Grantee agrees not to effect any sale or distribution of the Class 1 LTIP Units or any similar security of the Company or the Partnership, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the 1933 Act, during the fourteen (14) days prior to, and for a period of up to 180 days beginning on, the date of the pricing of any public or private debt or equity securities offering by the Company or the Partnership (except as part of such offering), if and to the extent requested in writing by the Partnership or the Company in the case of a non-underwritten public or private offering or if and to the extent requested in writing by the managing underwriter or underwriters (or initial purchaser or initial purchasers, as the case may be) and consented to by the Partnership or the Company, which consent may be given or withheld in the Partnership’s or the Company’s sole and absolute discretion, in the case of an underwritten public or private offering (such agreement to be in the form of a lock-up agreement provided by the Company, the Partnership, managing underwriter or underwriters, or initial purchaser or purchasers as the case may be).

12.Conformity to Securities Laws. The Grantee acknowledges that the Plan and this Agreement are intended to conform to the extent necessary with all provisions of all applicable federal and state laws, rules and regulations (including, but not limited to, the 1933 Act and the 1934 Act and any and all regulations and rules promulgated by the Securities and Exchange Commission thereunder, including without limitation the applicable exemptive conditions of Rule 16b-3 of the 1934 Act) and to such approvals by any listing, regulatory or other governmental authority as may, in the opinion of counsel for the Partnership or the Company, be necessary or advisable in connection therewith. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the award of Class 1 LTIP Units is made, only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by applicable law, the Plan, this Agreement and this award of Class 1 LTIP Units shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.

13.No Right of Continued Service. Nothing in this Agreement shall interfere with or limit in any way the right of the Company or any Parent or Subsidiary to terminate the Grantee’s service at any time, nor confer upon the Grantee any right to continue in the service of the Company or any Parent or Subsidiary.

14.Payment of Taxes.

(a) The Grantee covenants that the Grantee shall make a timely election under Section 83(b) of the Code (and any comparable election in the state of the Grantee’s residence) with respect to the Class 1 LTIP Units, and the Partnership hereby consents to the making of such election(s). In connection with such election, the Grantee and the Grantee’s spouse, if applicable, shall promptly provide a copy of such election to the Partnership. A form of election under Section 83(b) of the Code is attached hereto as Exhibit A. The Grantee represents that the Grantee has

consulted any tax advisor(s) that the Grantee deems advisable in connection with the filing of an election under Section 83(b) of the Code and similar state tax provisions. The Grantee acknowledges that it is the Grantee’s sole responsibility and not the Company’s or the Partnership’s to timely file an election under Section 83(b) of the Code (and any comparable state election), even if the Grantee requests that the Company, the Partnership or any representative thereof make such filing on the Grantee’s behalf. The Grantee should consult his or her tax advisor to determine if there is a comparable election to file in the state of his or her residence.

(b) The Grantee will, no later than the date as of which any amount related to the Class 1 LTIP Units first becomes includable in the Grantee’s gross income for federal income tax purposes, pay to the Company, or make other arrangements satisfactory to the Committee regarding payment of, any federal, state and local taxes of any kind required by law to be withheld with respect to such amount. For the avoidance of doubt, the Grantee may satisfy such payment by permitting the Company or the Partnership to reduce the number of Class 1 LTIP Units by an amount sufficient to satisfy the minimum amount (and not any greater amount) required to be withheld for tax purposes. The obligations of the Company and the Partnership under this Agreement will be conditional on such payment or arrangements, and the Company, and, where applicable, its Subsidiaries will, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the Grantee.

15.Profits Interests. The Partnership and the Grantee intend that (i) the Class 1 LTIP Units be treated as “profits interests” as defined in Internal Revenue Service Revenue Procedure 93-27, as clarified by Revenue Procedure 2001-43, (ii) the issuance of such units not be a taxable event to the Partnership or the Grantee as provided in such revenue procedures, and (iii) the Partnership Agreement, the Plan and this Agreement be interpreted consistently with such intent. In furtherance of such intent, effective immediately prior to the issuance of the Class 1 LTIP Units, the Partnership may revalue all Partnership assets to their respective gross fair market values, and make the resulting adjustments to the Capital Accounts of the Partners, in each case, as set forth in the Partnership Agreement.

16.Ownership Information. The Grantee hereby covenants that so long as the Grantee holds any Class 1 LTIP Units, at the request of the Partnership, the Grantee shall disclose to the Partnership in writing such information relating to the Grantee’s ownership of the Class 1 LTIP Units as the Partnership reasonably believes to be necessary or desirable to ascertain in order to comply with the Code or the requirements of any other appropriate taxing authority.

17.Grantee’s Covenant. The Grantee hereby agrees to use his best efforts to provide services to the Company in a workmanlike manner and to promote the Company’s interests.

18.Amendment. The Committee may amend, modify or terminate this Agreement without approval of the Grantee; provided, however, that such amendment, modification or termination shall not, without the Grantee’s consent, reduce or diminish the value of this award determined as if it had been fully vested on the date of such amendment or termination.

19.Plan Controls. The terms contained in the Plan are incorporated into and made a part of this Agreement and this Agreement shall be governed by and construed in accordance with the Plan. In the event of any actual or alleged conflict between the provisions of the Plan and the provisions of this Agreement, the provisions of the Plan shall be controlling and determinative.

20.Successors. This Agreement shall be binding upon any successor of the Company or the Partnership, in accordance with the terms of this Agreement and the Plan.

21.Severability. If any one or more of the provisions contained in this Agreement is invalid, illegal or unenforceable, the other provisions of this Agreement will be construed and enforced as if the invalid, illegal or unenforceable provision had never been included.

22.Notice. Notices and communications under this Agreement must be in writing and either personally delivered or sent by registered or certified United States mail, return receipt requested, postage prepaid. Notices to the Company or the Partnership must be addressed to:

Highlands Ranch, Colorado 80129

Attn: Corporate Secretary

or any other address designated by the Company or the Partnership in a written notice to the Grantee. Notices to the Grantee will be directed to the address of the Grantee then currently on file with the Company, or at any other address given by the Grantee in a written notice to the Company.

23.Dispute Resolution. The provisions of this Section 23 shall be the exclusive means of resolving disputes arising out of or relating to the Plan and this Agreement. The Company, the Grantee, and the Grantee’s assignees (the “parties”) shall attempt in good faith to resolve any disputes arising out of or relating to the Plan and this Agreement by negotiation between individuals who have authority to settle the controversy. Negotiations shall be commenced by either party by notice of a written statement of the party’s position and the name and title of the individual who will represent the party. Within thirty (30) days of the written notification, the parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to resolve the dispute. If the dispute has not been resolved by negotiation, the parties agree that any suit, action, or proceeding arising out of or relating to the Plan or this Agreement shall be brought in the United States District Court for the District of Colorado (or should such court lack jurisdiction to hear such action, suit or proceeding, in a state court in Colorado) and that the parties shall submit to the jurisdiction of such court. The parties irrevocably waive, to the fullest extent permitted by law, any objection the party may have to the laying of venue for any such suit, action or proceeding brought in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or more provisions of this Section 23 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable.
