(a)(i) On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, each of the Forward Seller (with respect to the Borrowed Underwritten Shares) and the Company (with respect to any Company Top-Up Underwritten Shares), severally and not jointly, agrees to sell to the several Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Forward Seller (with respect to the Borrowed Underwritten Shares) and the Company (with respect to any Company Top-Up Underwritten Shares) the respective number of Underwritten Shares set forth in Schedule I-A hereto opposite its name at $151.74 per share (the “Purchase Price”).

(ii) On the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, the Underwriters shall have the option to purchase pursuant to clause (A) or clause (B) below, as applicable, severally and not jointly, the Option Shares, at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Underwritten Shares but not payable on the Option Shares (the “Option Purchase Price”). The Representative may exercise the option, on behalf of the Underwriters, to purchase Option Shares at any time in whole or from time to time in part by giving written notice to the Company not later than 30 days after the date of this Agreement. Any exercise notice shall specify the number of Option Shares to be purchased by the Underwriters and the date on which such Option Shares are to be purchased. Each purchase date must be at least one but within three (3) business days after the written notice is given and may not be earlier than the Closing Date nor later than ten business days after the date of such notice. Following delivery of an exercise notice:

(A) The Company may, in its sole discretion, within one business day after such notice is given, execute and deliver to the Forward Seller an additional letter agreement substantially in the form attached hereto as Schedule II-A between the Company and the Forward Purchaser (the “Additional Forward Sale Agreement”) providing for the forward sale by the Company, subject to the Company’s right to elect Cash Settlement or Net Share Settlement (as such terms are defined in such Additional Forward Sale Agreement), of a number of shares of Common Stock equal to the aggregate number of Option Shares being purchased by the Underwriters from the Forward Seller pursuant to the exercise of such option. Upon the Company’s execution and delivery to the Forward Seller of such Additional Forward Sale Agreement, the Forward Purchaser shall promptly execute and deliver such Additional Forward Sale Agreement to the Company, and upon such execution and delivery to the Company, on the basis of the representations, warranties and agreements contained herein, and subject to the conditions stated herein, the Forward Seller (or, in the case of any Company Top-Up Option Shares, the Company) hereby agrees to sell to the several Underwriters such number of Option Shares at the Option Purchase Price.

(B) If the Company does not timely execute and deliver the Additional Forward Sale Agreement pursuant to clause (A) above, then on the basis of the representations, warranties and agreements contained in this Agreement, and subject to the terms and conditions stated herein, the Company hereby agrees to sell to the several Underwriters the aggregate number of Option Shares with respect to which the option is being exercised at the Option Purchase Price.

On each Date of Delivery, if any, each Underwriter agrees, severally and not jointly, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, to purchase from the Company or the Forward Seller, as applicable, at the Option Purchase Price, the number of Option Shares that bears the same ratio to the aggregate number of Option Shares being purchased on such Date of Delivery as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule I-A hereto (or such number increased as set forth in Section 14 hereof) bears to the aggregate number of Underwritten Shares being purchased by the several Underwriters, subject, however, to such adjustments to eliminate any fractional Shares as the Representative in its sole discretion shall make.

(the “1992 ISDA Master Agreement”), as they relate to the Forward Sale Agreement, and that the maximum number of shares of Common Stock initially issuable under the Forward Sale Agreement have been duly authorized and, upon issuance pursuant to the terms of the Forward Sale Agreement, will be validly issued, fully paid and nonassessable on or prior to the Closing Date (clauses (i) through (vii), together, the “Conditions”), the Forward Seller, in its sole discretion, may elect not to borrow and deliver for sale to the Underwriters the Borrowed Underwritten Shares. In addition, in the event that (A) in connection with establishing its commercially reasonable hedge position the Forward Seller or an affiliate thereof is unable, after using commercially reasonable efforts, to borrow and deliver for sale under this Agreement a number of shares of Common Stock equal to the number of Borrowed Underwritten Shares, or (B), in the Forward Purchaser’s sole judgment, the Forward Seller or its affiliate would incur a stock loan cost of more than 200 basis points per annum with respect to all or any portion of such shares to do so, then, in each case, the Forward Seller shall only be required to deliver for sale to the Underwriters on the Closing Date the aggregate number

As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters a prospectus relating to the Shares is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Shares by any Underwriter or dealer.

(c) Amendments or Supplements, Issuer Free Writing Prospectuses. Until in the opinion of counsel for the Underwriters a prospectus relating to the Shares is no longer required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Shares by any Underwriter or dealer, the Company, before using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus, and before filing any amendment or supplement to the Registration Statement or the Prospectus, will furnish to the Representative and counsel for the Underwriters a copy of the proposed Issuer Free Writing Prospectus, amendment or supplement for review and will not prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus or file any such proposed amendment or supplement to which the Representative reasonably objects.

(d) Notice to the Representative. The Company will advise the Representative promptly, and confirm such advice in writing, (i) when the Registration Statement has become effective; (ii) when any amendment to the Registration Statement has been filed or becomes effective; (iii) when any supplement to the Prospectus or any Issuer Free Writing Prospectus or any amendment to the Prospectus has been filed; (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (v) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (vi) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Time of Sale Information or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vii) of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act; and (viii) of the receipt by the Company of any notice with respect to any

suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Shares and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(e) Ongoing Compliance. (1) If during the Prospectus Delivery Period (i) any event shall occur or condition shall exist as a result of which the Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, not misleading, or (ii) it is necessary to amend or supplement the Prospectus to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission and furnish to the Underwriters and to such dealers as the Representative may designate, such amendments or supplements to the Prospectus as may be necessary so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances existing when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with law and (2) if at any time after the date of this Agreement (i) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances, not misleading, or (ii) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will immediately notify the Underwriters thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to the Underwriters and to such dealers as the Representative may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

(f) “Blue Sky” Compliance. The Company will qualify the Shares for offer and sale under the securities or “Blue Sky” laws of such jurisdictions as the Representative shall reasonably request and will continue such qualifications in effect so long as required for distribution of the Shares.

The Company shall either directly or indirectly apply the net proceeds from the sale of the Company Shares, if any, and the net proceeds, if any, due upon settlement of the Forward Sale Agreement or any Additional Forward Sale Agreement, in each case, as described in the Registration Statement, the Time of Sale Information and the Prospectus under the heading “Use of Proceeds.”

(j) No Stabilization. The Company shall not take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Shares.

(k) Exchange Listing. The Company shall use its best efforts to list on the New York Stock Exchange, subject to notice of issuance, (i) the Company Shares to be issued and sold by the Company hereunder, if any, and (ii) the maximum number of shares of Common Stock (if any) to be issued to the Forward Purchaser pursuant to the Forward Sale Agreement and any Additional Forward Sale Agreement, whether pursuant to Physical Settlement, Net Share Settlement or as a result of an Early Valuation (as such terms are defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable) or otherwise.

(l) Reports. During the period of 180 days from Closing Date or any Date of Delivery or, in the case of the Forward Seller, until the expiration or termination of the Forward

If immediately prior to the third anniversary of February 27, 2012 (such third anniversary, the “Renewal Deadline”) any of the Shares remain unsold by the Underwriters, the Company shall, prior to the Renewal Deadline, promptly notify the Underwriters and the Forward Seller and file, if it has not already done so and is eligible to do so, an automatic shelf registration statement (as defined in Rule 405 of the 1933 Act Regulations) relating to the Shares, in a form satisfactory to the Representative and the Forward Seller. If at the Renewal Deadline any of the Shares remain unsold by the Underwriters and the Company is not eligible to file an automatic shelf registration statement, the Company shall, if it has not already done so, promptly notify the Underwriters and the Forward Seller and file a new shelf registration statement or post-effective amendment on the proper form relating to the Shares in a form satisfactory to the Representative and the Forward Seller, and shall use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable after the Renewal Deadline and promptly notify the Underwriters and the Forward Seller of such effectiveness. The Company shall take all other action necessary or appropriate to permit the public offering and sale of the Shares to continue as contemplated in the expired registration statement relating thereto. References herein to the “Registration Statement” shall include such automatic shelf registration statement or such new shelf registration statement or post-effective amendment, as the case may be.

11. Indemnification and Contribution.

(a) Indemnification of the Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, the Forward Purchaser and the Forward Seller, each of their respective affiliates (including broker-dealer affiliates), directors and officers and each person, if any, who controls such Underwriter, the Forward Purchaser or the Forward Seller within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any Time of Sale Information (including any Time of Sale Information that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter, the Forward Purchaser or the Forward Seller furnished to the Company in writing by such Underwriter, the Forward Purchaser or the Forward Seller through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter, the Forward Purchaser or the Forward Seller consists of the information described as such in subsection (b) below.

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement, the Forward Purchaser, the Forward Seller, each of the directors and officers of the Forward Purchaser and Forward Seller, and each person, if any, who controls the Company, the Forward Purchaser or the Forward Seller within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed upon that the only such information furnished by any

Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the last paragraph on the cover page concerning delivery of the Shares; and the first sentence of the third paragraph of text under the heading “Underwriting” concerning the price at which the Underwriters propose to offer the shares.

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 11 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 11. If any such proceeding shall be brought or asserted against an Indemnified Person and such Indemnified Person shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary or (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, the Forward Purchaser and the Forward Seller, each of their respective affiliates, directors and officers and any control persons of such Underwriter, Forward Purchaser or Forward Seller shall be designated in writing by the Representative and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement or compromise of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than thirty (30) days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened

action, claim or proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person (whether or not the Indemnified Person is an actual or potential party to such action, claim or proceeding), unless such settlement or compromise (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability arising out of such action, claim or proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Person, on the one hand, and the Indemnified Person on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Indemnifying Person, on the one hand, and the Indemnified Person on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Underwriters and the Forward Seller shall be deemed to be in the same respective proportions as (x) in the case of the Company, the net proceeds (before deducting expenses) received by the Company (which proceeds shall include the proceeds that would be received by the Company pursuant to the Forward Sale Agreement and any Additional Forward Sale Agreement assuming Physical Settlement (as such term is defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as applicable) of the Forward Sale Agreement and any Additional Forward Sale Agreement on the Effective Date (as such term is defined in the Forward Sale Agreement or Additional Forward Sale Agreement, as the case may be)), (y) in the case of the Underwriters, the total underwriting discounts and commissions received by the Underwriters and (z) in the case of the Forward Seller, the aggregate Spread (as defined in the Forward Sale Agreement and any Additional Forward Sale Agreement) retained by the Forward Purchaser under the Forward Sale Agreement and any Additional Forward Sale Agreement, net of any costs associated therewith, as reasonably determined by the Forward Seller, in each case bear to the aggregate offering price of the Shares plus such Spread, net of any such costs. The relative fault of the Indemnifying Person, on the one hand, and the Indemnified Person on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Underwriters or the Forward Seller and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company, the Forward Seller, the Forward Purchaser and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one

entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 11, (A) in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (B) the Forward Seller shall not be required to contribute an amount in excess of the aggregate Spread (as defined in the Forward Sale Agreement and any Additional Forward Sale Agreement) retained by the Forward Purchaser under the Forward Sale Agreement and any Additional Forward Sale Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 11 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

12. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

13. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after the execution and delivery of this Agreement and prior to delivery and payment for the Shares, (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, the NYSE MKT LLC, FINRA, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

14. Defaulting Underwriter. (a) If, on the Closing Date or as of each Date of Delivery, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company, in the case of Company Shares, or the Forward Seller and the Forward Purchaser, in the case of

Borrowed Shares, on the terms contained in this Agreement. If, within thirty-six (36) hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company, in the case of Company Shares, or the Forward Seller and the Forward Purchaser, in the case of Borrowed Shares, shall be entitled to a further period of thirty-six (36) hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Date of Delivery, as the case may be, for up to five (5) full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” or “Underwriters” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed on Schedule I-A hereto that, pursuant to this Section 14, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Forward Seller, the Forward Purchaser and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Date of Delivery, as the case may be, does not exceed one eleventh (1/11th) of the aggregate number of Shares to be purchased on such date, then the Company, in the case of Company Shares, or the Forward Seller or the Forward Purchaser, in the case of Borrowed Shares, shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Forward Seller, the Forward Purchaser and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Date of Delivery, as the case may be, exceeds one eleventh (1/11th) of the aggregate amount of Shares to be purchased on such date, or if the Company, in the case of Company Shares, or the Forward Seller or the Forward Purchaser, in the case of Borrowed Shares, shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Date of Delivery, the obligation of the Underwriters to purchase Shares on the Date of Delivery, as the case may be, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 14 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 16 hereof and except that the provisions of Section 11 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

15. Additional Issuance and Sale by the Company. (a) In the event that (i) all the Conditions are not satisfied on or prior to the Closing Date or, in respect of any Additional Forward Sale Agreement entered into pursuant to Section 2(a)(ii)(A), all the Additional Conditions are not satisfied on any relevant Date of Delivery, as the case may be, and the Forward Seller elects, pursuant to Section 2(b) or Section 2(c) hereof, as the case may be, not to deliver the total number of Borrowed Underwritten Shares or Borrowed Option Shares, as applicable, deliverable by the Forward Seller hereunder, (ii) the Forward Seller or an affiliate thereof is unable, after using commercially reasonable efforts, to borrow and deliver for sale under this Agreement a number of shares of Common Stock equal to the total number of the Borrowed Underwritten Shares or Borrowed Option Shares, as applicable, or (iii) in the Forward Purchaser’s sole judgment, the Forward Seller or its affiliate would incur a stock loan cost of more than 25 basis points per annum to borrow and deliver for sale under this Agreement the total number of Borrowed Underwritten Shares or Borrowed Option Shares, as applicable, then, in each case, the Company shall issue and sell to the Underwriters on the Closing Date or the relevant Date of Delivery, pursuant to Section 2 hereof, in whole but not in part, an aggregate number of shares of Common Stock equal to the number of Borrowed Underwritten Shares or Borrowed Option Shares, as the case may be, that the Forward Seller does not so deliver and sell to the Underwriters. In connection with any such issuance and sale by the Company, the Company or the Representative shall have the right to postpone the Closing Date or the relevant Date of Delivery, as the case may be, for a period not exceeding one business day in order to effect any required changes in any documents or arrangements. The shares of Common Stock sold by the Company to the Underwriters pursuant to this Section 15(a) in lieu of any Borrowed Underwritten Shares are referred to herein as the “Company Top-Up Underwritten Shares,” and the shares of Common Stock sold by the Company to the Underwriters pursuant to this Section 15(a) in lieu of any Borrowed Option Shares are referred to herein as the “Company Top-Up Option Shares.”

16. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement, the Forward Sale Agreement or any Additional Forward Sale Agreement are

consummated or this Agreement, the Forward Sale Agreement or any Additional Forward Sale Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations under this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement, including, without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Shares and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing this Agreement, the Forward Sale Agreement and any Additional Forward Sale Agreement and any documents related hereto and thereto; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Shares under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a “Blue Sky” memorandum (including the related fees and expenses of counsel for the Underwriters); (vi) the cost of preparing stock certificates; (vii) the costs and charges of any transfer agent and any registrar; (viii) all expenses and application fees, if any, incurred in connection with any filing with, and clearance of the offering by, FINRA; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (x) all expenses and application fees related to the listing of any Company Shares and any shares issuable pursuant to the Forward Sale Agreement or any Additional Forward Sale Agreement on the New York Stock Exchange.

Re:	Issuer Share Forward Sale Transaction

Ref. No:	[Insert Reference Number]

Date:	[Insert Trade Date]

Dear Sir(s):

The purpose of this communication (this “Confirmation”) is to set forth the terms and conditions of the above-referenced transaction entered into on the Trade Date specified below (the “Transaction”) between Goldman, Sachs & Co. (“GS&Co.”) and AvalonBay Communities, Inc. (“Counterparty”). This communication constitutes a “Confirmation” as referred to in the Agreement specified below. This Confirmation is a confirmation for purposes of Rule 10b-10 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

1. This Confirmation is subject to, and incorporates, the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International Swaps and Derivatives Association, Inc. (“ISDA”). For purposes of the Equity Definitions, the Transaction will be deemed to be a Share Forward Transaction.

This Confirmation shall supplement, form a part of and be subject to an agreement (the “Agreement”) in the form of the 1992 ISDA Master Agreement (Multicurrency—Cross Border) (the “ISDA Form”), as published by ISDA, as if GS&Co. and Counterparty had executed the ISDA Form on the date hereof (but without any Schedule except for (i) the election of Loss and Second Method, New York law (without regard to New York’s choice of laws doctrine other than Title 14 of Article 5 of the New York General Obligations Law) as the governing law and US Dollars (“USD”) as the Termination Currency, (ii) the replacement of the word “third” in the last line of Section 5(a)(i) with the word “first” and (iii) the election that the “Cross Default” provisions of Section 5(a)(vi) shall apply to GS&Co. and Counterparty with a “Threshold Amount” in respect of GS&Co. of 3% of the stockholders’ equity of The Goldman Sachs Group, Inc. and a “Threshold Amount” in respect of Counterparty of (A) zero in respect of Specified Indebtedness incurred under (1) the Third Amended and Restated Revolving Loan Agreement (the “Credit Facility”), dated as of September 29, 2011, among Counterparty and the several financial institutions party thereto, as amended by Amendment No. 1 to the Third Amended and Restated Revolving Loan Agreement, dated as of December 20, 2012, and as may be further amended from time to time, (2) any successor to the Credit Facility or any other credit facility of Counterparty that represents Counterparty’s principal credit facility at such time or (3) the Term Loan Agreement, dated as of March 31, 2014, among Counterparty, Wells Fargo Bank, National Association, PNC Bank, National Association and the other lenders party thereto, as amended from time to time, (B) USD200 million in respect of Specified Indebtedness assumed by Counterparty or its affiliates in connection with Counterparty’s acquisition of the assets and liabilities of Archstone Enterprise LP and (C) USD135 million in respect of all other Specified Indebtedness; provided that (x) the words “, or becoming capable at such time of being declared,” shall be deleted from clause (1) thereof and (y) the following language shall be added to the end of such Section 5(a)(vi): “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (X) the default was caused solely by error or omission of an administrative or operational nature; (Y)

funds were available to enable the party to make the payment when due; and (Z) the payment is made within two Local Business Days of such party’s receipt of written notice of its failure to pay;”).

All provisions contained in the Agreement are incorporated into and shall govern this Confirmation except as expressly modified below. This Confirmation evidences a complete and binding agreement between GS&Co. and Counterparty as to the terms of the Transaction and replaces any previous agreement between the parties with respect to the subject matter hereof.

The Transaction hereunder shall be the sole Transaction under the Agreement. If there exists any ISDA Master Agreement between GS&Co. or any of its Affiliates, including The Goldman Sachs Group, Inc. (collectively, “Goldman Sachs”), and Counterparty or any confirmation or other agreement between Goldman Sachs and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Goldman Sachs and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which Goldman Sachs and Counterparty are parties, the Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement. In the event of any inconsistency among the Agreement, this Confirmation and the Equity Definitions, the following will prevail in the order of precedence indicated: (i) this Confirmation; (ii) the Equity Definitions; and (iii) the Agreement.

Settlement Price:	For any Cash Settlement, the arithmetic average of the 10b-18 VWAP on each Unwind Date relating to such settlement, plus 0.05% of such amount.

	For any Net Share Settlement, the weighted average price of the purchases of Shares made by GS&Co. (or its agent or affiliate) during the Unwind Period in connection with unwinding its commercially reasonable hedge position relating to such Settlement (weighted based

	on the number of Shares purchased by GS&Co. or its agent or affiliate on each Unwind Date in connection with unwinding its commercially reasonable hedge position in connection with such Settlement, as determined by the Calculation Agent), plus USD0.02.

10b-18 VWAP:	For any Exchange Business Day, as determined by the Calculation Agent based on the New York 10b-18 Volume Weighted Average Price per Share for the regular trading session (including any extensions thereof) of the Exchange on such Exchange Business Day (without regard to pre-open or after hours trading outside of such regular trading session for such Exchange Business Day), as published by Bloomberg at 4:15 p.m. New York time (or 15 minutes following the end of any extension of the regular trading session) on such Exchange Business Day, on Bloomberg page “AVB.N <Equity> AQR_SEC” (or any successor thereto), or if such price is not so reported on such Exchange Business Day for any reason or is, in the Calculation Agent’s reasonable determination, erroneous, such 10b-18 VWAP shall be as reasonably determined by the Calculation Agent. For purposes of calculating the 10b-18 VWAP for such Exchange Business Day, the Calculation Agent will include only those trades that are reported during the period of time during which Counterparty could purchase its own shares under Rule 10b-18(b)(2) and are effected pursuant to the conditions of Rule 10b-18(b)(3), each under the Exchange Act (such trades, “Rule 10b-18 eligible transactions”).

Unwind Activities:	The times and prices at which GS&Co. (or its agent or affiliate) purchases any Shares during any Unwind Period in connection with unwinding its commercially reasonable hedge position shall be determined by GS&Co. in a commercially reasonable manner. Without limiting the generality of the foregoing, in the event that GS&Co. concludes, in its reasonable discretion based on advice of counsel, that it is appropriate with respect to any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by GS&Co.) (a “Regulatory Disruption”), for it to refrain from purchasing Shares in connection with unwinding its commercially reasonable hedge position on any Scheduled Trading Day that would have been an Unwind Date but for the occurrence of a Regulatory Disruption, GS&Co. may (but shall not be required to) notify Counterparty in writing that a Regulatory Disruption has occurred on such Scheduled Trading Day, in which case GS&Co. shall, to the extent practicable in its good faith discretion, specify the nature of such Regulatory Disruption, and, for the avoidance of doubt, such Scheduled Trading Day shall not be an Unwind Date and such Regulatory Disruption shall be deemed to be a Market Disruption Event; provided that GS&Co. may exercise its right to suspend under this sentence only in good faith in relation to events or circumstances that are not the result of actions of it or any of its Affiliates that are taken with the intent to avoid its obligations under the Transaction.

Relevant Settlement Date:	For any Settlement, the Settlement Date, Cash Settlement Payment Date or Net Share Settlement Date, as the case may be.

Other Applicable Provisions:	To the extent GS&Co. is obligated to deliver Shares hereunder, the provisions of Sections 9.2 (last sentence only), 9.8, 9.9, 9.10, 9.11 and 9.12 of the Equity Definitions will be applicable as if “Physical

	Settlement” applied to the Transaction; provided that the Representation and Agreement contained in Section 9.11 of the Equity Definitions shall be modified by excluding any representations therein relating to restrictions, obligations, limitations or requirements under applicable securities laws that exist as a result of the fact that Counterparty is the issuer of the Shares.

Share Adjustments:

Potential Adjustment Events:	An Extraordinary Dividend shall not constitute a Potential Adjustment Event. For the avoidance of doubt, a cash dividend on the Shares that differs from expected dividends as of the Trade Date shall not be a Potential Adjustment Event under Section 11.2(e)(vii) of the Equity Definitions.

Extraordinary Dividend:	Any dividend or distribution on the Shares with an ex-dividend date occurring on any day following the Trade Date (other than (i) any dividend or distribution of the type described in Section 11.2(e)(i) or Section 11.2(e)(ii)(A) of the Equity Definitions or (ii) a regular, quarterly cash dividend in an amount equal to or less than the Regular Dividend Amount for such calendar quarter that has an ex-dividend date no earlier than the Forward Price Reduction Date occurring in the relevant quarter).

Regular Dividend Amount:	For each calendar quarter, as set forth on Annex B.

Method of Adjustment:	Calculation Agent Adjustment

Extraordinary Events:

Extraordinary Events:	The consequences that would otherwise apply under Article 12 of the Equity Definitions to any applicable Extraordinary Event (excluding any Failure to Deliver, Increased Cost of Hedging, Increased Cost of Stock Borrow or any Extraordinary Event that also constitutes a Bankruptcy Termination Event, but including, for the avoidance of doubt, any other applicable Additional Disruption Event) shall not apply.

Tender Offer:	Applicable; provided that Section 12.1(d) of the Equity Definitions shall be amended by replacing the reference therein to “10%” with a reference to “20%”.

Delisting:	In addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it shall also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any such exchange or quotation system, such exchange or quotation system shall be deemed to be the Exchange.

	(including, without limitation, any tax law) or (ii) the promulgation of or any change in or public announcement of the formal or informal interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law or regulation (including any action taken by a taxing authority), in each case, constitutes a “Change in Law” shall be made without regard to Section 739 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 or any similar legal certainty provision in any legislation enacted, or rule or regulation promulgated, on or after the Trade Date, (B) Section 12.9(a)(ii) of the Equity Definitions is hereby amended (i) by adding the words “(including, for the avoidance of doubt and without limitation, adoption or promulgation of new regulations authorized or mandated by existing statute)” after the word “regulation” in the second line thereof and (ii) by replacing the words “the interpretation” with the words “or public announcement of any formal or informal interpretation” in the third line thereof and (C) the words “, unless the illegality is due to an act or omission of the party seeking to elect termination of the Transaction with the intent to avoid its obligations under the terms of the Transaction” are added immediately following the word “Transaction” in the fifth line thereof; and provided further that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by adding the phrase “and/or Hedge Position” after the word “Shares” in clause (X) thereof and (iii) by immediately following the word “Transaction” in clause (X) thereof, adding the phrase “in the manner contemplated by the Hedging Party on the Trade Date”.

Failure to Deliver:	Applicable if GS&Co. is required to deliver Shares hereunder; otherwise, Not Applicable.

Hedging Disruption:	Applicable

Increased Cost of Hedging:	Applicable; provided that Section 12.9(b)(vi) of the Equity Definitions shall be amended by (i) deleting clause (C) of the second sentence thereof and (ii) deleting the third and fourth sentences thereof.

Increased Cost of Stock Borrow:	Applicable; provided that Section 12.9(b)(v) of the Equity Definitions shall be amended by (i) deleting clause (C) of the second sentence thereof and (ii) deleting the third, fourth and fifth sentences thereof. For the avoidance of doubt, upon the announcement of any event that, if consummated, would result in a Merger Event or Tender Offer, the term “rate to borrow Shares” as used in Section 12.9(a)(viii) of the Equity Definitions shall include any commercially reasonable cost borne or amount payable by the Hedging Party in respect of maintaining or reestablishing its hedge position, including, but not limited to, any assessment or other amount payable by the Hedging Party to a lender of Shares in respect of any merger or tender offer premium, as applicable.

(or, in the case of an ISDA Event that is an Event of Default or Termination Event, the party entitled to designate an Early Termination Date in respect of such event pursuant to Section 6 of the Agreement) shall have the right to designate any Scheduled Trading Day to be the “Early Valuation Date”, in which case the provisions set forth in this “Early Valuation” section shall apply, in the case of an Event of Default or Termination Event, in lieu of Section 6 of the Agreement. For the avoidance of doubt, any amount calculated pursuant to this “Early Valuation” section as a result of an Extraordinary Dividend shall not be adjusted by the value associated with such Extraordinary Dividend.

	GS&Co. represents and warrants to and agrees with Counterparty that (i) based upon advice of counsel, GS&Co. (A) does not know of the existence on the Trade Date of an Excess Section 13 Ownership Position, an Excess NYSE Ownership Position or an Excess Regulatory Ownership Position and (B) based on reasonable internal inquiry in the ordinary course of GS&Co.’s business does not know on the Trade Date of any event or circumstance that will cause the occurrence of an Excess Section 13 Ownership Position, an Excess NYSE Ownership Position or an Excess Regulatory Ownership Position on any day during the term of the Transaction; and (ii) GS&Co. will not knowingly cause the occurrence of an Excess Section 13 Ownership Position, an Excess NYSE Ownership Position or an Excess Regulatory Ownership Position on any day during the term of the Transaction for the purpose, in whole or in part, of causing the occurrence of an Early Valuation Date.

	If the Early Valuation Date occurs on a date that is not during an Unwind Period, then the Early Valuation Date shall be a Valuation Date for a Physical Settlement, and the number of Settlement Shares for such Settlement shall be the Number of Shares on the Early Valuation Date; provided that GS&Co. may in its sole discretion permit Counterparty to elect Cash Settlement or Net Share Settlement.

	If the Early Valuation Date occurs during an Unwind Period, then (i) (A) the last Unwind Date of such Unwind Period shall be deemed to be the Early Valuation Date, (B) a Settlement shall occur in respect of such Unwind Period, and the Settlement Method elected by Counterparty in respect of such Settlement shall apply, and (C) the number of Settlement Shares for such Settlement shall be the number of Unwound Shares for such Unwind Period on the Early Valuation Date, and (ii) (A) the Early Valuation Date shall be a Valuation Date for an

	additional Physical Settlement (provided that GS&Co. may in its sole discretion elect that the Settlement Method elected by Counterparty for the Settlement described in clause (i) of this sentence shall apply) and (B) the number of Settlement Shares for such additional Settlement shall be the number of Remaining Shares on the Early Valuation Date.

	Notwithstanding the foregoing, in the case of a Nationalization or Merger Event, if at the time of the related Relevant Settlement Date the Shares have changed into cash or any other property or the right to receive cash or any other property, the Calculation Agent shall adjust the nature of the Shares as it determines appropriate to account for such change such that the nature of the Shares is consistent with what shareholders receive in such event.

ISDA Event:	(i) Any Event of Default or Termination Event, other than an Event of Default or Termination Event that also constitutes a Bankruptcy Termination Event, that gives rise to the right of either party to designate an Early Termination Date pursuant to Section 6 of the Agreement or (ii) the announcement of any event or transaction that, if consummated, would result in a Merger Event, Tender Offer, Nationalization, Delisting or Change in Law, in each case, as determined by the Calculation Agent.

Amendment to Merger Event:	Section 12.1(b) of the Equity Definitions is hereby amended by deleting the remainder of such Section beginning with the words “in each case if the Merger Date is on or before” in the fourth to last line thereof.

Hedging Event:	(i) (x) A Loss of Stock Borrow in connection with which Counterparty does not refer the Hedging Party to a satisfactory Lending Party within the required time period as provided in Section 12.9(b)(iv) of the Equity Definitions or (y) a Hedging Disruption, (ii) (A) an Increased Cost of Stock Borrow or (B) an Increased Cost of Hedging in connection with which, in the case of sub-clause (A) or (B), Counterparty does not elect, and so notify the Hedging Party of its election, in each case, within the required time period to either amend the Transaction pursuant to Section 12.9(b)(v)(A) or Section 12.9(b)(vi)(A) of the Equity Definitions, as applicable, or pay an amount determined by the Calculation Agent that corresponds to the relevant Price Adjustment pursuant to Section 12.9(b)(v)(B) or Section 12.9(b)(vi)(B) of the Equity Definitions, as applicable, or (iii) the occurrence of a Market Disruption Event during an Unwind Period and the continuance of such Market Disruption Event for at least eight Scheduled Trading Days.

Remaining Shares:	On any day, the Number of Shares as of such day (or, if such day occurs during an Unwind Period, the Number of Shares as of such day minus the Unwound Shares for such Unwind Period on such day).

Unwound Shares:	For any Unwind Period on any day, the aggregate number of Shares with respect to which GS&Co. has unwound its commercially reasonable hedge position in respect of the Transaction in connection with the related Settlement as of such day.

Transfer:	Notwithstanding anything to the contrary in the Agreement, GS&Co. may assign, transfer and set over all rights, title and interest, powers, privileges and remedies of GS&Co. under the Transaction, in whole or in part, to an affiliate of GS&Co. whose obligation is guaranteed by The Goldman Sachs Group, Inc. without the consent of Counterparty; provided that (x) Counterparty will neither (1) be required to pay, nor is there a material likelihood that it would be required to pay, an additional amount in respect of an Indemnifiable Tax under Section 2(d)(i)(4) of the Agreement, nor (2) receive a payment, nor is there a material likelihood that it would receive a payment, from which an amount has been deducted or withheld for or on account of any Indemnifiable Tax in respect of which the other party is not required to pay an additional amount, in either case as a result of such transfer or assignment and (y) no Event of Default or Potential Event of Default shall have occurred with respect to either party solely as a result of such transfer and assignment.

Following any determination or calculation by the Calculation Agent hereunder, upon a written request by Counterparty, the Calculation Agent will, within a commercially reasonable period of time following such request, provide to Counterparty by e-mail to the e-mail address provided by Counterparty in such written request a report (in a commonly used file format for the storage and manipulation of financial data) displaying in reasonable detail the basis for such determination or calculation, as the case may be; provided that GS&Co. shall not be required to disclose any proprietary or confidential models of GS&Co. or any information that is proprietary or subject to contractual, legal or regulatory obligations to not disclose such information.

3. Effectiveness.

The effectiveness of this Confirmation and the Transaction shall be subject to the following conditions:

(a) the representations and warranties of Counterparty contained in the Underwriting Agreement dated the date hereof between Counterparty and GS&Co., as representative of the Underwriters party thereto (the “Underwriting Agreement”), and any certificate delivered pursuant thereto by Counterparty shall be true and correct on the Effective Date as if made as of the Effective Date;

(b) Counterparty shall have performed all of the obligations required to be performed by it under the Underwriting Agreement on or prior to the Effective Date;

(d) the Date of Delivery (as defined in the Underwriting Agreement) shall have occurred as provided in the Underwriting Agreement;

(e) all of the representations and warranties of Counterparty hereunder and under the Agreement shall be true and correct on the Effective Date as if made as of the Effective Date;

(f) Counterparty shall have performed all of the obligations required to be performed by it hereunder and under the Agreement on or prior to the Effective Date, including without limitation its obligations under Section 6 hereof; and

(g) Counterparty shall have delivered to GS&Co. an opinion of counsel in form and substance reasonably satisfactory to GS&Co., with respect to the matters set forth in Section 3(a) of the Agreement and that the maximum number of Shares initially issuable hereunder have been duly authorized and, upon issuance pursuant to the terms of the Transaction, will be validly issued, fully paid and nonassessable.

Notwithstanding the foregoing or any other provision of this Confirmation, if (x) on or prior to 9:00 a.m., New York City time, on the date the Date of Delivery (as defined in the Underwriting Agreement) is scheduled to occur, in connection with establishing its commercially reasonable hedge position GS&Co., in its sole judgment, is unable, after using commercially reasonable efforts, to borrow and deliver for sale the Full Number of Shares or (y) in GS&Co.’s sole judgment, it would incur a stock loan cost of more than 200 basis points per annum with respect to all or any portion of the Full Number of Shares (in each case, an “Initial Hedging Disruption”), the effectiveness of this Confirmation and the Transaction shall be limited to the number of Shares GS&Co. is so able to borrow in connection with establishing its commercially reasonable hedge position at a cost of not more than 200 basis points

per annum (such number of Shares, the “Reduced Number of Shares”), which, for the avoidance of doubt, may be zero.

4. Additional Mutual Representations and Warranties. In addition to the representations and warranties in the Agreement, each party represents and warrants to the other party that it is an “eligible contract participant”, as defined in the U.S. Commodity Exchange Act (as amended), and an “accredited investor” as defined in Section 2(a)(15)(ii) of the Securities Act of 1933 (as amended) (the “Securities Act”), and is entering into the Transaction hereunder as principal and not for the benefit of any third party.

5. Additional Representations and Warranties of Counterparty. In addition to the representations and warranties in the Agreement and those contained elsewhere herein, Counterparty represents and warrants to GS&Co., and agrees with GS&Co., that:

(a) without limiting the generality of Section 13.1 of the Equity Definitions, it acknowledges that GS&Co. is not making any representations or warranties with respect to the treatment of the Transaction, including without limitation ASC Topic 260, Earnings Per Share, ASC Topic 815, Derivatives and Hedging, ASC Topic 480, Distinguishing Liabilities from Equity, ASC 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity (or any successor issue statements) or under the Financial Accounting Standards Board’s Liabilities & Equity Project;

(b) it shall not take any action to reduce or decrease the number of authorized and unissued Shares below the sum of (i) the Number of Shares plus (ii) the total number of Shares issuable upon settlement (whether by net share settlement or otherwise) of any other transaction or agreement to which it is a party;

(c) it will not repurchase any Shares if, immediately following such repurchase, the sum of (x) the Number of Shares hereunder and (y) the “Number of Shares” as such term is defined in the Base Confirmation would be equal to or greater than 4.5% of the number of then-outstanding Shares and it will notify GS&Co. immediately upon the announcement or consummation of any repurchase of Shares in an amount that, taken together with the amount of all repurchases since the date of the last such notice (or, if no such notice has been given, since the Trade Date), exceeds 0.5% of the number of then-outstanding Shares;

(d) it is not entering into this Confirmation to create actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for Shares), or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for Shares) for the purpose of inducing the purchase or sale of the Shares (or any security convertible into or exchangeable for Shares) by others;

(e) neither it nor any of its officers, directors, managers or similar persons is aware of any material non-public information regarding itself or the Shares; it is entering into this Confirmation and will provide any Settlement Notice in good faith and not as part of a plan or scheme to evade compliance with Rule 10b-5 or any other provision of the federal securities laws; it has not entered into or altered any hedging transaction relating to the Shares corresponding to or offsetting the Transaction; and it has consulted with its own advisors as to the legal aspects of its adoption and implementation of this Confirmation under Rule 10b5-1 under the Exchange Act (“Rule 10b5-1”);

(f) no state or local (including non-U.S. jurisdictions) law, rule, regulation or regulatory order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without limitation a requirement to obtain prior approval from any person or entity) as a result of GS&Co. or its affiliates owning or holding (however defined) Shares; provided that Counterparty makes no such representation or warranty regarding any such requirement that is applicable generally to the ownership of equity securities by GS&Co.;

(g) as of the Trade Date and as of the date of any payment or delivery by Counterparty or GS&Co. hereunder, it is not and will not be “insolvent” (as such term is defined under Section 101(32) of the Bankruptcy Code);

(h) it is not, and after giving effect to the transactions contemplated hereby will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended;

(i) it: (i) is an “institutional account” as defined in FINRA Rule 4512(c); and (ii) is capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities, and will exercise independent judgment in evaluating any recommendations of GS&Co. or its associated persons; and

(j) IT UNDERSTANDS THAT THE TRANSACTION IS SUBJECT TO COMPLEX RISKS WHICH MAY ARISE WITHOUT WARNING AND MAY AT TIMES BE VOLATILE AND THAT LOSSES MAY OCCUR QUICKLY AND IN UNANTICIPATED MAGNITUDE AND IS WILLING TO ACCEPT SUCH TERMS AND CONDITIONS AND ASSUME (FINANCIALLY AND OTHERWISE) SUCH RISKS.

6. Additional Covenants of Counterparty.

(a) Counterparty acknowledges and agrees that any Shares delivered by Counterparty to GS&Co. on any Settlement Date or Net Share Settlement Date will be (i) newly issued, (ii) approved for listing or quotation on the Exchange, subject to official notice of issuance, and (iii) registered under the Exchange Act, and, when delivered by GS&Co. (or an affiliate of GS&Co.) to securities lenders from whom GS&Co. (or an affiliate of GS&Co.) borrowed Shares in connection with hedging its exposure to the Transaction, will be freely saleable without further registration or other restrictions under the Securities Act in the hands of those securities lenders, irrespective of whether any such stock loan is effected by GS&Co. or an affiliate of GS&Co. Accordingly, Counterparty agrees that any Shares so delivered will not bear a restrictive legend and will be deposited in, and the delivery thereof shall be effected through the facilities of, the Clearance System. In addition, Counterparty represents and agrees that any such Shares shall be, upon such delivery, duly and validly authorized, issued and outstanding, fully paid and nonassessable, free of any lien, charge, claim or other encumbrance.

(b) Counterparty agrees that Counterparty shall not enter into or alter any hedging transaction relating to the Shares corresponding to or offsetting the Transaction. Without limiting the generality of the provisions set forth opposite the caption “Unwind Activities” in Section 2 of this Confirmation, Counterparty acknowledges that it has no right to, and agrees that it will not seek to, control or influence GS&Co.’s decision to make any “purchases or sales” (within the meaning of Rule 10b5-1(c)(1)(i)(B)(3)) under or in connection with the Transaction, including, without limitation, GS&Co.’s decision to enter into any hedging transactions.

(c) Counterparty acknowledges and agrees that any amendment, modification, waiver or termination of this Confirmation must be effected in accordance with the requirements for the amendment or termination of a “plan” as defined in Rule 10b5-1(c). Without limiting the generality of the foregoing, any such amendment, modification, waiver or termination shall be made in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5, and no such amendment, modification or waiver shall be made at any time at which Counterparty or any officer, director, manager or similar person of Counterparty is aware of any material non-public information regarding Counterparty or the Shares.

(d) Counterparty shall promptly provide notice thereof to GS&Co. (i) upon the occurrence of any event that would constitute an Event of Default or a Termination Event in respect of which Counterparty is a Defaulting Party or an Affected Party, as the case may be, and (ii) upon announcement of any event that, if consummated, would constitute an Extraordinary Event or Potential Adjustment Event.

(e) Neither Counterparty nor any of its “affiliated purchasers” (as defined by Rule 10b-18 under the Exchange Act (“Rule 10b-18”)) shall take any action that would cause any purchases of Shares by GS&Co. or any of its Affiliates in connection with any Cash Settlement or Net Share Settlement not to meet the requirements of the safe harbor provided by Rule 10b-18 if such purchases were made by Counterparty. Without limiting the generality of the foregoing, during any Unwind Period, except with the prior written consent of GS&Co., Counterparty will not, and will cause its affiliated purchasers (as defined in Rule 10b-18) not to, directly or indirectly (including, without limitation, by means of a derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or announce or commence any tender offer relating to, any Shares (or equivalent interest,

including a unit of beneficial interest in a trust or limited partnership or a depository share) or any security convertible into or exchangeable for the Shares.

(f) Counterparty will not be subject to any “restricted period” (as such term is defined in Regulation M promulgated under the Exchange Act (“Regulation M”)) in respect of Shares or any security with respect to which the Shares are a “reference security” (as such term is defined in Regulation M) during any Unwind Period.

(g) Counterparty shall: (i) prior to the opening of trading in the Shares on any day on which Counterparty makes, or expects to be made, any public announcement (as defined in Rule 165(f) under the Securities Act) of any Merger Transaction, notify GS&Co. of such public announcement; (ii) promptly notify GS&Co. following any such announcement that such announcement has been made; (iii) promptly (but in any event prior to the next opening of the regular trading session on the Exchange) provide GS&Co. with written notice specifying (A) Counterparty’s average daily Rule 10b-18 Purchases (as defined in Rule 10b-18) during the three full calendar months immediately preceding the announcement date for the Merger Transaction that were not effected through GS&Co. or its affiliates and (B) the number of Shares purchased pursuant to the proviso in Rule 10b-18(b)(4) under the Exchange Act for the three full calendar months preceding such announcement date. Such written notice shall be deemed to be a certification by Counterparty to GS&Co. that such information is true and correct. In addition, Counterparty shall promptly notify GS&Co. of the earlier to occur of the completion of such transaction and the completion of the vote by target shareholders. Counterparty acknowledges that any such notice may result in a Regulatory Disruption, a Trading Condition or, if such notice relates to an event that is also an ISDA Event, an Early Valuation, or may affect the length of any ongoing Unwind Period; accordingly, Counterparty acknowledges that its delivery of such notice must comply with the standards set forth in Section 6(c) above. “Merger Transaction” means any merger, acquisition or similar transaction involving a recapitalization as contemplated by Rule 10b-18(a)(13)(iv) under the Exchange Act. For the avoidance of doubt, a Merger Transaction or the announcement thereof shall not give either party the right to designate an Early Valuation Date and/or to accelerate or preclude an election by Counterparty of Physical Settlement, unless such Merger Transaction or the announcement thereof is also an ISDA Event.

7. Termination on Bankruptcy. The parties hereto agree that, notwithstanding anything to the contrary in the Agreement or the Equity Definitions, the Transaction constitutes a contract to issue a security of Counterparty as contemplated by Section 365(c)(2) of the Bankruptcy Code and that the Transaction and the obligations and rights of Counterparty and GS&Co. (except for any liability as a result of breach of any of the representations or warranties provided by Counterparty in Section 4 or Section 5 above) shall immediately terminate, without the necessity of any notice, payment (whether directly, by netting or otherwise) or other action by Counterparty or GS&Co., if, on or prior to the final Settlement Date, Cash Settlement Payment Date or Net Share Settlement Date, an Insolvency Filing occurs or any other proceeding commences with respect to Counterparty under the Bankruptcy Code (a “Bankruptcy Termination Event”).

8. Additional Provisions.

(a) GS&Co. acknowledges and agrees that Counterparty’s obligations under the Transaction are not secured by any collateral and that this Confirmation is not intended to convey to GS&Co. rights with respect to the transactions contemplated hereby that are senior to the claims of common stockholders in any U.S. bankruptcy proceedings of Counterparty; provided that nothing herein shall limit or shall be deemed to limit GS&Co.’s right to pursue remedies in the event of a breach by Counterparty of its obligations and agreements with respect to this Confirmation or the Agreement; provided further that nothing herein shall limit or shall be deemed to limit GS&Co.’s rights in respect of any transaction other than the Transaction.

(b) GS&Co. represents and warrants to Counterparty that, as of the Trade Date, the obligations of GS&Co. under this Confirmation are fully and unconditionally guaranteed by The Goldman Sachs Group, Inc. as set forth in the General Guarantee Agreement, dated January 30, 2006, a copy of which is available at http://www.sec.gov/Archives/edgar/data/886982/000095012306001208/y16720exv10w45.htm (the “GS Guarantee”). For the avoidance of doubt, the GS Guarantee shall not be a Credit Support Document hereunder, and The Goldman Sachs Group, Inc. shall not be a Credit Support Provider of GS&Co. hereunder.

(i) the Transaction to be a “securities contract” as defined in Section 741(7) of the Bankruptcy Code, and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections 362(b)(6), 362(b)(27), 362(o), 546(e), 546(j), 555 and 561 of the Bankruptcy Code;

(ii) the rights given to GS&Co. pursuant to “Early Valuation” in Section 2 above to constitute “contractual rights” to cause the liquidation of a “securities contract” and to set off mutual debts and claims in connection with a “securities contract”, as such terms are used in Sections 555 and 362(b)(6) of the Bankruptcy Code;

(iii) any cash, securities or other property provided as performance assurance, credit support or collateral with respect to the Transaction to constitute “margin payments” and “transfers” under a “securities contract” as defined in the Bankruptcy Code;

(iv) all payments for, under or in connection with the Transaction, all payments for Shares and the transfer of Shares to constitute “settlement payments” and “transfers” under a “securities contract” as defined in the Bankruptcy Code; and

(v) any or all obligations that either party has with respect to this Confirmation or the Agreement to constitute property held by or due from such party to margin, guaranty or settle obligations of the other party with respect to the transactions under the Agreement (including the Transaction) or any other agreement between such parties.

(d) Notwithstanding any other provision of the Agreement or this Confirmation, in no event will Counterparty be required to deliver in the aggregate in respect of all Settlement Dates, Net Share Settlement Dates or other dates on which Shares are delivered in respect of any amount owed under this Agreement a number of Shares greater than [ ](2) (the “Capped Number”). The Capped Number shall be subject to adjustment only on account of (x) Potential Adjustment Events of the type specified in (1) Sections 11.2(e)(i) through (vi) of the Equity Definitions or (2) Section 11.2(e)(vii) of the Equity Definitions so long as, in the case of this sub-clause (2), such event is within Issuer’s control, (y) Merger Events requiring corporate action of Issuer (or any surviving entity of the Issuer hereunder in connection with any such Merger Event) and (z) Announcement Events that are not outside Issuer’s control. Counterparty represents and warrants to GS&Co. (which representation and warranty shall be deemed to be repeated on each day that the Transaction is outstanding) that the Capped Number is equal to or less than the number of authorized but unissued Shares that are not reserved for future issuance in connection with transactions in the Shares (other than the Transaction) on the date of the determination of the Capped Number (such Shares, the “Available Shares”). In the event Counterparty shall not have delivered the full number of Shares otherwise deliverable as a result of this Section 8(c) (the resulting deficit, the “Deficit Shares”), Counterparty shall be continually obligated to deliver Shares, from time to time until the full number of Deficit Shares have been delivered pursuant to this paragraph, when, and to the extent that, (A) Shares are repurchased, acquired or otherwise received by Counterparty or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other consideration), (B) authorized and unissued Shares reserved for issuance in respect of other transactions prior to such date which prior to the relevant date become no longer so reserved and (C) Counterparty additionally authorizes any unissued Shares that are not reserved for other transactions (such events as set forth in clauses (A), (B) and (C) above, collectively, the “Share Issuance Events”). Counterparty shall promptly notify GS&Co. of the occurrence of any of the Share Issuance Events (including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares to be delivered) and, as promptly as reasonably practicable, deliver such Shares thereafter. Counterparty shall not, until Counterparty’s obligations under the Transaction have been satisfied in full, use any Shares that become available for potential delivery to GS&Co. as a result of any Share Issuance Event for the settlement or satisfaction of any transaction or obligation other than the Transaction or reserve any such Shares for future issuance for any purpose other than to satisfy Counterparty’s obligations to GS&Co. under the Transaction.

(2) Insert two times the Number of Shares as of the Trade Date.

(e) The parties intend for this Confirmation to constitute a “Contract” as described in the letter dated October 6, 2003 submitted on behalf of GS&Co. to Paula Dubberly of the staff of the Securities and Exchange Commission (the “Staff”) to which the Staff responded in an interpretive letter dated October 9, 2003.

(f) The parties intend for this Transaction (taking into account purchases of Shares in connection with any Cash Settlement or Net Share Settlement) to comply with the requirements of Rule 10b5-1(c)(1)(i)(A) under the Exchange Act and for this Confirmation to constitute a binding contract or instruction satisfying the requirements of 10b5-1(c) and to be interpreted to comply with the requirements of Rule 10b5-1(c).

(g) Notwithstanding any provisions of the Agreement, all communications relating to the Transaction or the Agreement shall be transmitted exclusively through GS&Co. at 200 West Street, New York, New York 10282-2198, Telephone No. (212) 902-1981, Facsimile No. (212) 428-1980/1983.

(h) Counterparty acknowledges that:

(i) during the term of the Transaction, GS&Co. and its affiliates may buy or sell Shares or other securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to establish, adjust or unwind its hedge position with respect to the Transaction;

(ii) GS&Co. and its affiliates may also be active in the market for the Shares and derivatives linked to the Shares other than in connection with hedging activities in relation to the Transaction, including acting as agent or as principal and for its own account or on behalf of customers;

(iii) GS&Co. shall make its own determination as to whether, when or in what manner any hedging or market activities in Counterparty’s securities shall be conducted and shall do so in a manner that it deems appropriate to hedge its price and market risk with respect to the Forward Price and the Settlement Price;

(iv) any market activities of GS&Co. and its affiliates with respect to the Shares may affect the market price and volatility of the Shares, as well as the Forward Price and the Settlement Price, each in a manner that may be adverse to Counterparty; and

(v) the Transaction is a derivatives transaction; GS&Co. may purchase or sell shares for its own account at an average price that may be greater than, or less than, the price received by Counterparty under the terms of the Transaction.

9. Indemnification. Counterparty agrees to indemnify and hold harmless GS&Co., its affiliates and its assignees and their respective directors, officers, employees, agents and controlling persons (GS&Co. and each such person being an “Indemnified Party”) from and against any and all losses (excluding, for the avoidance of doubt, financial losses resulting from the economic terms of the Transaction), claims, damages and liabilities (or actions in respect thereof), joint or several, incurred by or asserted against such Indemnified Party arising out of, in connection with, or relating to, the execution or delivery of this Confirmation, the performance by the parties hereto of their respective obligations under the Transaction, any breach of any covenant or representation made by Counterparty in this Confirmation or the Agreement or the consummation of the transactions contemplated hereby. Counterparty will not be liable under the foregoing indemnification provision to the extent that any loss, claim, damage, liability or expense is found in a nonappealable judgment by a court of competent jurisdiction to have resulted from GS&Co.’s willful misconduct, gross negligence or bad faith in performing the services that are subject of the Transaction. If for any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold harmless any Indemnified Party, then Counterparty shall contribute, to the maximum extent permitted by law, to the amount paid or payable by the Indemnified Party as a result of such loss, claim, damage or liability. In addition, Counterparty will reimburse any Indemnified Party for all reasonable expenses (including reasonable counsel fees and expenses) as they are incurred in connection with the investigation of, preparation for or defense or settlement of any pending or threatened claim or any action, suit or proceeding arising therefrom, whether or not such Indemnified Party is a party thereto and whether or not such claim, action, suit or proceeding is initiated or brought by or on behalf of Counterparty. Counterparty also agrees that no Indemnified Party shall have any liability

to Counterparty or any person asserting claims on behalf of or in right of Counterparty in connection with or as a result of any matter referred to in this Confirmation except to the extent that any losses, claims, damages, liabilities or expenses incurred by Counterparty result from the gross negligence, willful misconduct or bad faith of the Indemnified Party. The provisions of this Section 9 shall survive the completion of the Transaction contemplated by this Confirmation and any assignment and/or delegation of the Transaction made pursuant to the Agreement or this Confirmation shall inure to the benefit of any permitted assignee of GS&Co. For the avoidance of doubt, any payments due as a result of this provision may not be used to set off any obligation of GS&Co. upon settlement of the Transaction.

10. Beneficial Ownership. Notwithstanding anything to the contrary in the Agreement or this Confirmation, in no event shall GS&Co. be entitled to receive, or be deemed to receive, or have the “right to acquire” (within the meaning of NYSE Rule 312.04(g)) Shares to the extent that, upon such receipt of such Shares, and after taking into account any Shares concurrently deliverable to GS&Co. pursuant to the Base Confirmation, (i) the “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and the rules promulgated thereunder) of Shares by GS&Co., any of its affiliates’ business units subject to aggregation with GS&Co. for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act and all persons who may form a “group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with GS&Co. with respect to “beneficial ownership” of any Shares (collectively, “GS Group”) would be equal to or greater than the lesser of (x) 4.5% of the outstanding Shares (such condition, an “Excess Section 13 Ownership Position”), and (y) [ ](3) Shares (such number of Shares, the “Threshold Number of Shares” and such condition, the “Excess NYSE Ownership Position”) or (ii) GS&Co., GS Group or any person whose ownership position would be aggregated with that of GS&Co. or GS Group (GS&Co., GS Group or any such person, a “GS Person”) under Sections 3-601 through 3-603 of the Maryland Code (Corporations and Associations) or any state or federal bank holding company or banking laws, or any federal, state or local laws, regulations or regulatory orders applicable to ownership of Shares (“Applicable Laws”), would own, beneficially own, constructively own, control, hold the power to vote or otherwise meet a relevant definition of ownership in excess of a number of Shares equal to (x) the lesser of (A) the maximum number of Shares that would be permitted under Applicable Laws and (B) the number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a GS Person under Applicable Laws and with respect to which such requirements have not been met or the relevant approval has not been received or that would give rise to any consequences under the constitutive documents of Counterparty (including, without limitation, Section 9.2(a) of Counterparty’s Restated Articles of Incorporation (as amended from time to time)) or any contract or agreement to which Counterparty is a party, in each case minus (y) 1% of the number of Shares outstanding on the date of determination (such condition described in clause (ii), an “Excess Regulatory Ownership Position”). If any delivery owed to GS&Co. hereunder is not made, in whole or in part, as a result of this provision, (i) Counterparty’s obligation to make such delivery shall not be extinguished and Counterparty shall make such delivery as promptly as practicable after, but in no event later than one Exchange Business Day after, GS&Co. gives notice to Counterparty that such delivery would not, after taking into account any Shares concurrently deliverable to GS&Co. pursuant to the Base Confirmation, result in (x) GS Group directly or indirectly so beneficially owning in excess of the lesser of (A) 4.5% of the outstanding Shares and (B) the Threshold Number of Shares or (y) the occurrence of an Excess Regulatory Ownership Position and (ii) if such delivery relates to a Physical Settlement, notwithstanding anything to the contrary herein, GS&Co. shall not be obligated to satisfy the portion of its payment obligation corresponding to any Shares required to be so delivered until the date Counterparty makes such delivery.

11. Non-Confidentiality. The parties hereby agree that (i) effective from the date of commencement of discussions concerning the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind, including opinions or other tax analyses, provided by GS&Co. and its affiliates to Counterparty relating to such tax treatment and tax structure; provided that the foregoing does not constitute an authorization to disclose the identity of GS&Co. or its affiliates, agents or advisers, or, except to the extent relating to such tax structure or tax treatment, any specific pricing terms or commercial or financial information, and (ii) GS&Co. does not assert any claim of proprietary ownership in respect of any description

(3) To be 4.9% of the outstanding Shares as of the Trade Date.

contained herein or therein relating to the use of any entities, plans or arrangements to give rise to a particular United States federal income tax treatment for Counterparty.

12. Restricted Shares. If Counterparty is unable to comply with the covenant of Counterparty contained in Section 6 above or GS&Co. otherwise determines in its reasonable opinion that any Shares to be delivered to GS&Co. by Counterparty may not be freely returned by GS&Co. to securities lenders as described in the covenant of Counterparty contained in Section 6 above, then delivery of any such Settlement Shares (the “Unregistered Settlement Shares”) shall be effected pursuant to Annex A hereto, unless waived by GS&Co.

13. Use of Shares. GS&Co. acknowledges and agrees that, except in the case of a Private Placement Settlement, GS&Co. shall use any Shares delivered by Counterparty to GS&Co. on any Settlement Date to return to securities lenders to close out borrowings created by GS&Co. in connection with its hedging activities related to exposure under this Transaction or otherwise in compliance with applicable law.

14. Rule 10b-18. In connection with bids and purchases of Shares in connection with any Net Share Settlement or Cash Settlement of the Transaction, GS&Co. shall use commercially reasonable efforts to conduct its activities, or cause its affiliates to conduct their activities, in a manner consistent with the requirements of the safe harbor provided by Rule 10b-18 under the Exchange Act, as if such provisions were applicable to such purchases and taking into account any applicable Securities and Exchange Commission no-action letters as appropriate, and subject to any delays between the execution and reporting of a trade of the Shares on the Exchange and other circumstances beyond GS&Co.’s control.

15. Governing Law. Notwithstanding anything to the contrary in the Agreement, the Agreement, this Confirmation and all matters arising in connection with the Agreement and this Confirmation shall be governed by, and construed and enforced in accordance with, the laws of the State of New York (without reference to its choice of laws doctrine other than Title 14 of Article 5 of the New York General Obligations Law).

16. Set-Off.

(a) The parties agree that upon the occurrence of an Event of Default or Termination Event with respect to a party who is the Defaulting Party or the Affected Party (“X”), the other party (“Y”) will have the right (but not be obliged) without prior notice to X or any other person to set-off or apply any obligation of X owed to Y (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation) against any obligation of Y owed to X (whether or not matured or contingent and whether or not arising under the Agreement, and regardless of the currency, place of payment or booking office of the obligation). Y will give notice to the other party of any set-off effected under this Section 16.

Amounts (or the relevant portion of such amounts) subject to set-off may be converted by Y into the Termination Currency at the rate of exchange at which such party would be able, acting in a reasonable manner and in good faith, to purchase the relevant amount of such currency. If any obligation is unascertained, Y may in good faith estimate that obligation and set-off in respect of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained. Nothing in this Section 16 shall be effective to create a charge or other security interest. This Section 16 shall be without prejudice and in addition to any right of set-off, combination of accounts, lien or other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).

(b) Notwithstanding anything to the contrary in the foregoing, GS&Co. agrees not to set off or net amounts due from Counterparty with respect to any Transaction against amounts due from GS&Co. to Counterparty with respect to contracts or instruments that are not Equity Contracts. “Equity Contract” means any transaction or instrument that does not convey to GS&Co. rights, or the ability to assert claims, that are senior to the rights and claims of common stockholders in the event of Counterparty’s bankruptcy and would be classified as equity according to generally accepted accounting principles in the United States.

17. Staggered Settlement. Notwithstanding anything to the contrary herein, GS&Co. may, by prior notice to Counterparty, satisfy its obligation to deliver any Shares or other securities on any date due (an “Original Delivery Date”) by making separate deliveries of Shares or such securities, as the case may be, at more than one time on or prior to such Original Delivery Date, so long as the aggregate number of Shares and other securities so delivered on or prior to such Original Delivery Date is equal to the number required to be delivered on such Original Delivery Date.

18. Arbitration.

(a) All parties to this Confirmation are giving up the right to sue each other in court, including the right to a trial by jury, except as provided by the rules of the arbitration forum in which a claim is filed.

(b) Arbitration awards are generally final and binding; a party’s ability to have a court reverse or modify an arbitration award is very limited.

(c) The ability of the parties to obtain documents, witness statements and other discovery is generally more limited in arbitration than in court proceedings.

(d) The arbitrators do not have to explain the reason(s) for their award.

(e) The panel of arbitrators will typically include a minority of arbitrators who were or are affiliated with the securities industry, unless Counterparty is a member of the organization sponsoring the arbitration facility, in which case all arbitrators may be affiliated with the securities industry.

(f) The rules of some arbitration forums may impose time limits for bringing a claim in arbitration. In some cases, a claim that is ineligible for arbitration may be brought in court.

(g) The rules of the arbitration forum in which the claim is filed, and any amendments thereto, shall be incorporated into this Confirmation.

(h) Counterparty agrees that any and all controversies that may arise between Counterparty and GS&Co. arising out of or relating to the Agreement or any Transaction hereunder shall be determined by arbitration conducted before the FINRA Dispute Resolution (“FINRA-DR”), or, if the FINRA-DR declines to hear the matter, before the American Arbitration Association, in accordance with their arbitration rules then in force. The award of the arbitrator shall be final, and judgment upon the award rendered may be entered in any court, state or federal, having jurisdiction.

(i) No person shall bring a putative or certified class action to arbitration, nor seek to enforce any pre-dispute arbitration agreement against any person who has initiated in court a putative class action or who is a member of a putative class who has not opted out of the class with respect to any claims encompassed by the putative class action until: (i) the class certification is denied; (ii) the class is decertified; or (iii) Counterparty is excluded from the class by the court.

(j) Such forbearance to enforce an agreement to arbitrate shall not constitute a waiver of any rights under this Confirmation except to the extent stated herein.

19. Counterparts. This Confirmation may be executed in any number of counterparts, all of which shall constitute one and the same instrument, and any party hereto may execute this Confirmation by signing and delivering one or more counterparts.

20. Delivery of Cash. For the avoidance of doubt, nothing in this Confirmation shall be interpreted as requiring Counterparty to deliver cash or other assets in respect of the settlement of the Transaction, except in circumstances where the required cash or other asset settlement thereof is permitted for classification of the contract as equity by ASC 815-40, Derivatives and Hedging — Contracts in Entity’s Own Equity, as in effect on the Trade Date.

Counterparty hereby agrees (a) to check this Confirmation carefully and immediately upon receipt so that errors or discrepancies can be promptly identified and rectified and (b) to confirm that the foregoing (in the exact form provided by GS&Co.) correctly sets forth the terms of the agreement between GS&Co. and Counterparty with respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement to such terms and providing the other information requested herein and immediately returning an executed copy to Equity Derivatives Documentation Department, Facsimile No. 212-428-1980/83.

ANNEX A

PRIVATE PLACEMENT PROCEDURES

If Counterparty delivers Unregistered Settlement Shares pursuant to Section 12 above (a “Private Placement Settlement”), then:

(a) all Unregistered Settlement Shares shall be delivered to GS&Co. (or any affiliate of GS&Co. designated by GS&Co.) pursuant to the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof;

(b) as of or prior to the date of delivery, GS&Co. and any potential purchaser of any such shares from GS&Co. (or any affiliate of GS&Co. designated by GS&Co.) identified by GS&Co. shall be afforded a commercially reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for private placements of equity securities of similar size (including, without limitation, the right to have made available to them for inspection all financial and other records, pertinent corporate documents and other information reasonably requested by them);

(c) as of the date of delivery, Counterparty shall enter into an agreement (a “Private Placement Agreement”) with GS&Co.. (or any affiliate of GS&Co. designated by GS&Co.) in connection with the private placement of such shares by Counterparty to GS&Co. (or any such affiliate) and the private resale of such shares by GS&Co. (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities of similar size, in form and substance commercially reasonably satisfactory to GS&Co., which Private Placement Agreement shall include, without limitation, provisions substantially similar to those contained in such private placement purchase agreements relating, without limitation, to the indemnification of, and contribution in connection with the liability of, GS&Co. and its affiliates and obligations to use best efforts to obtain customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters, and shall provide for the payment by Counterparty of all commercially reasonable fees and expenses in connection with such resale, including all commercially reasonable fees and expenses of counsel for GS&Co., and shall contain representations, warranties, covenants and agreements of Counterparty reasonably necessary or advisable to establish and maintain the availability of an exemption from the registration requirements of the Securities Act for such resales; and

(d) in connection with the private placement of such shares by Counterparty to GS&Co. (or any such affiliate) and the private resale of such shares by GS&Co. (or any such affiliate), Counterparty shall, if so requested by GS&Co., prepare, in cooperation with GS&Co., a private placement memorandum in form and substance reasonably satisfactory to GS&Co..

In the case of a Private Placement Settlement, GS&Co. shall, in its good faith discretion, adjust the amount of Unregistered Settlement Shares to be delivered to GS&Co. hereunder in a commercially reasonable manner to reflect the fact that such Unregistered Settlement Shares may not be freely returned to securities lenders by GS&Co. and may only be saleable by GS&Co. at a discount to reflect the lack of liquidity in Unregistered Settlement Shares.

If Counterparty delivers any Unregistered Settlement Shares in respect of the Transaction, Counterparty agrees that (i) such Shares may be transferred by and among GS&Co. and its affiliates and (ii) after the minimum “holding period” within the meaning of Rule 144(d) under the Securities Act has elapsed after the applicable Settlement Date, Counterparty shall promptly remove, or cause the transfer agent for the Shares to remove, any legends referring to any transfer restrictions from such Shares upon delivery by GS&Co. (or such affiliate of GS&Co.) to Counterparty or such transfer agent of seller’s and broker’s representation letters customarily delivered by GS&Co. or its affiliates in connection with resales of restricted securities pursuant to Rule 144 under the Securities Act, each without any further requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any transfer tax stamps or payment of any other amount or any other action by GS&Co. (or such affiliate of GS&Co.).

September [ ], 2014

Goldman, Sachs & Co.

As Representative of the

several Underwriters

200 West Street

New York, New York 10282

Re: AvalonBay Communities, Inc. — Lock-Up Agreement

Dear Sirs:

We refer to the Underwriting Agreement (the “Underwriting Agreement”), dated September 9, 2014, between AvalonBay Communities, Inc., a Maryland corporation (the “Company”), the Forward Seller (as defined therein), the Forward Purchaser (as defined therein) and you as Representative of the Underwriters named therein (the “Underwriters”), relating to the underwritten public offering (the “Offering”) of 4,500,000 shares (the “Shares”) of common stock, par value $0.01 per share, of the Company (the “Common Stock”).

In recognition of the benefit that such an offering will confer upon the undersigned as a stockholder and an officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with the Underwriters that, during a period of 30 days from the date of the Underwriting Agreement, such period not to exceed 30 days, the undersigned will not, without the prior written consent of the Representative, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of Common Stock or any securities convertible into, exchangeable or exercisable for, or that represent the right to receive shares of Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition (except as set forth below) or whether owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the Securities and Exchange Commission, or file or make any demand for the filing of, any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing (collectively, the “Lock-Up Securities”), or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Lock-Up Securities, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise. The foregoing sentence is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Lock-Up Securities even if the Lock-Up Securities would be disposed of by someone other than the undersigned. Such prohibited hedging or other

transactions would include, without limitation, any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Lock-Up Securities or with respect to any security that includes, relates to, or derives any significant part of its value from the Lock-Up Securities.

The restrictions set forth in the foregoing paragraph shall not apply to (a) transactions relating to shares of Common Stock or other securities acquired in open market transactions after the completion of the Offering, (b) the exercise for cash of any stock option, provided that all shares issued upon exercise are subject to the restrictions hereof, (c) the delivery of shares of Common Stock to the Company for cancellation (or the withholding and cancellation of shares of Common Stock by the Company) as payment for (i) the exercise price of any stock option granted in the ordinary course pursuant to any of the Company’s current or future employee or director stock option, incentive or benefit plans, or (ii) the withholding taxes due upon the exercise of any such stock option or the vesting of any restricted shares of Common Stock granted under any such plan provided that (i) no filing by any party under the Exchange Act shall be required or shall be voluntarily made in connection with such exercise or vesting other than a Form 4 (which shall explain in a footnote the reason for such filing) and (ii) all net shares received upon such exercise or vesting are subject to the restrictions hereof, (d) sales pursuant to plans complying with the safe harbor provided by Rule 10b5-1 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that were entered into prior to the date hereof, (e) a foreclosure by a bona fide lender upon shares which on the date hereof are pledged to secure a loan, provided that the officers or directors providing such pledge used reasonable efforts to prevent such foreclosure, or (f) any transfer of shares of Common Stock as a bona fide gift or gifts, provided that, in the case of a gift of greater than 7,500 shares of Common Stock or a gift to a donee that is not a tax-exempt charitable organization or foundation, the donee or donees thereof agree to be bound in writing by the restrictions set forth herein; provided, that in the case of any transactions relating to shares of Common Stock or other securities acquired in open market transactions pursuant to clause (a), no filing by any party under the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Common Stock or other securities acquired in such open market transactions.

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the Offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns. If for any reason the Underwriting Agreement shall be terminated prior to the Closing Date (as defined in the Underwriting Agreement), the agreement set forth above shall likewise be terminated.
