8.                                       Covenants of the Underwriters .  Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

9.                                       Indemnity and Contribution.   (a) Each of the Company, the General Partner and the Operating Partnership, jointly and severally, agrees to indemnify and hold harmless each Underwriter, the Forward Purchaser, the Forward Seller, each person, if any, who controls any Underwriter, the Forward Purchaser, or the Forward Seller within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter, the Forward Purchaser, or the Forward Seller within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show as defined in Rule 433(h) under the Securities Act (a “road show”), or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter, the Forward

29

Purchaser or the Forward Seller furnished to the Company in writing by such Underwriter, the Forward Purchaser or the Forward Seller through you expressly for use therein.

(b)                    Each Underwriter, the Forward Purchaser and the Forward Seller agrees, severally and not jointly, to indemnify and hold harmless the Company, the General Partner, the Operating Partnership, their respective directors and officers, each person, if any, who controls the Company, the General Partner or the Operating Partnership within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of the Company, the General Partner and the Operating Partnership within the meaning of Rule 405 under the Securities Act to the same extent as the foregoing indemnity from the Company, the General Partner and the Operating Partnership to such Underwriter, the Forward Purchaser and the Forward Seller set forth in Section 9(a) above, but only with reference to information relating to such 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 you expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show, or the Prospectus or any amendment or supplement thereto.  The Company, General Partner and the Operating Partnership acknowledge that: (i) the only information furnished in writing by or on behalf of the Underwriters for inclusion in the Prospectus shall be (x) such Underwriter’s name on the cover of the Prospectus, (y) such Underwriter’s name in the first table under the caption “Underwriting” in the Prospectus; and (z) the first two sentences of the third paragraph under the caption “Underwriting” in the Prospectus and (ii) the only information furnished in writing by or on behalf of the Forward Purchaser or Forward Seller for inclusion in the Prospectus shall be such Forward Purchaser’s or Forward Seller’s name on the cover of the Prospectus and the Forward Purchaser’s name in the first paragraph under the caption “Underwriting—Forward Sale Agreement” in the Prospectus.

(c)                     In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 9(a) or 9(b) such person (the “ indemnified party ”) shall promptly notify the person against whom such indemnity may be sought (the “ indemnifying party ”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding.  In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, including different defenses.  It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings 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 such indemnified parties and that all such fees and expenses shall be

30

reimbursed as they are incurred.  Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 9(a), by the Company, the General Partner and the Operating Partnership, in the case of parties indemnified pursuant to Section 9(b).  The indemnifying party shall not be liable for any settlement 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 party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment.  No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)                    To the extent the indemnification provided for in Section 9(a) or 9(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 Company, the General Partner and the Operating Partnership, on the one hand, and the Underwriters, the Forward Purchaser and the Forward Seller, on the other hand, from the offering of the Shares or (ii) if the allocation provided by clause 9(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 9(d)(i) above but also the relative fault of the Company, the General Partner and the Operating Partnership, on the one hand, and of the Underwriters, the Forward Purchaser and the Forward Seller, on the other hand, 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 General Partner and the Operating Partnership, on the one hand, and the Underwriters, the Forward Purchaser and the Forward Seller, on the other hand, in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company, the General Partner and the Operating Partnership (which proceeds shall include the proceeds to be received by the Company pursuant to the Forward Sale Agreement assuming Physical Settlement (as such term is defined in the Forward Sale Agreement) of the Forward Sale Agreement on the Effective Date (as such term is defined in the Forward Sale Agreement)), the total underwriting discounts and commissions received by the Underwriters and the aggregate absolute difference between the Daily Rate and the USD-Federal Funds Rate (as such terms are defined in the Forward Sale Agreement) received by the Forward Purchaser under the Forward Sale Agreement, net of any costs associated therewith, as reasonably determined by the Forward Seller, bear to the aggregate Public Offering Price of the Shares.  The relative fault of the Company, the General Partner and the Operating Partnership, on the one hand, and the Underwriters, the Forward Purchaser and the Forward Seller, on the other hand, 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

31

relates to information supplied by the Company, the General Partner and the Operating Partnership or by the Underwriters, the Forward Purchaser or the Forward Seller and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Underwriters’, the Forward Purchaser’s or the Forward Seller’s respective obligations to contribute pursuant to this Section 9 are several and not joint.

The Company, the General Partner, the Operating Partnership, the Underwriters, the Forward Purchaser and the Forward Seller agree that it would not be just or equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters, the Forward Purchaser or the Forward Seller 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 Section 9(d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 9(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 9, no Underwriter, Forward Purchaser or Forward Seller (except as may be provided in any agreement among Underwriters, the Forward Purchaser or the Forward Seller relating to the offering of the Shares) shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by such Underwriter and distributed to the public were offered to the public or, with respect to the Forward Seller and the Forward Purchaser, the aggregate absolute difference between the Daily Rate and the USD-Federal Funds Rate (as such terms are defined in the Forward Sale Agreement) received by the Forward Purchaser under the Forward Sale Agreement, net of any costs associated therewith, as reasonably determined by the Forward Seller, as applicable, exceeds the amount of any damages that such Underwriter, Forward Purchaser or Forward Seller has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  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 remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(e)                     The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Company, the General Partner and the Operating Partnership contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, the Forward Purchaser or the Forward Seller, any person controlling any Underwriter, the Forward Purchaser or the Forward Seller or any affiliate of any Underwriter, the Forward Purchaser or the Forward Seller or by or on behalf of the Company, its officers or directors, the General Partner, the Operating Partnership or any person controlling the Company, the General Partner and the Operating Partnership and (iii) acceptance of and payment for any of the Shares.

11.                  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, and the Forward Seller elects, pursuant to Section 3(c), not to deliver the Borrowed Shares deliverable by the Forward Seller, (ii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller is unable to borrow and deliver for sale under this Agreement a number of shares of Common Stock equal to the number of the Borrowed Shares to be borrowed and delivered for sale by the Forward Seller under this Agreement or (iii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller would incur a stock loan cost of more than a rate equal to 25 basis points per annum to do so, in each case, the Company shall issue and sell to the Underwriters, pursuant to Section 3 hereof, in whole but not in part, an aggregate number of shares of Common Stock equal to the number of Borrowed Shares 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 Representatives shall have the right to postpone the Closing Date for a period not exceeding three business days 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 11(a) in lieu of Borrowed Shares are referred to herein as the “ Company Top-Up Underwritten Shares ”.

(b)                    Neither the Forward Purchaser nor the Forward Seller shall have any liability whatsoever for any Borrowed Shares that the Forward Seller does not deliver and sell to the Underwriters or any other party if (i) all of the Conditions are not satisfied on or prior to the Closing Date and the Forward Seller elects, pursuant to Section 3(c), not to deliver and sell to the Underwriters the Borrowed Shares, (ii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller is unable to borrow and deliver for sale under this Agreement on the Closing Date a number of shares of Common Stock equal to the number of the Borrowed Shares to be borrowed and delivered for sale by the Forward Seller under this Agreement or (iii) in the Forward Purchaser’s commercially reasonable judgment, the Forward Seller would incur a stock loan cost of more than a rate equal to 25 basis points per annum to do so.

12.                  Termination .  (a) In the case of the Underwritten Shares, the Underwriters or the Forward Seller may terminate this Agreement by notice given by the Representatives or the Forward Seller, as applicable, to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date, or (b) in the case of the Option Shares, the Underwriters may terminate this Agreement by notice given by the Representatives to the Company if after the execution and delivery of this Agreement and prior to the Additional Closing Date, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, the New York Stock Exchange or NASDAQ, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed

33

with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Registration Statement, the Time of Sale Prospectus or the Prospectus.

13.                  Effectiveness; Defaulting Underwriters .  This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Additional Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Underwritten Shares set forth opposite their respective names in Schedule I hereto bears to the aggregate number of Underwritten Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter.  If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Underwritten Shares and the aggregate number of Underwritten Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Underwritten Shares to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Underwritten Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company, the General Partner or the Operating Partnership.  In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected.  If, on an Additional Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Option Shares and the aggregate number of Option Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Option Shares to be purchased on such Additional Closing Date, the non-defaulting Underwriters shall have the option to (i)  terminate their obligation hereunder to purchase the Option Shares to be sold on such Additional Closing Date or (ii) purchase not less than the number of Option Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default.  Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company, General Partner, or Operating Partnership to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company, General Partner, or Operating Partnership shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all

34

out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

14.                  Research Analyst Independence . Each of the Company, the General Partner and the Operating Partnership acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. Each of the Company, the General Partner and the Operating Partnership acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the Transactions.

15.                  Entire Agreement .  (a) This Agreement, together with any contemporaneous written agreements (including the Forward Sale Agreement) and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company, the General Partner, the Operating Partnership, the Underwriters, the Forward Seller and the Forward Purchaser with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b)                    Each of the Company, the General Partner and the Operating Partnership acknowledges that in connection with the offering of the Shares:(i) the Underwriters, the Forward Purchaser and the Forward Seller have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company, the General Partner and the Operating Partnership or any other person, (ii) the Underwriters, the Forward Purchaser and the Forward Seller owe the Company, the General Partner and the Operating Partnership only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters, the Forward Purchaser and the Forward Seller may have interests that differ from those of the Company, the General Partner and the Operating Partnership, and (iv) none of the Underwriters, the Forward Purchaser and the Forward Seller is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the Transactions, and none of the Underwriters, the Forward Purchaser and the Forward Seller shall have any responsibility or liability to the Company with respect thereto. Any review by the Underwriters, the Forward Purchaser or the Forward Seller of the Company, the Transactions or other matters relating to the Transactions will be performed solely for the benefit of the Underwriters, the Forward Purchaser or the Forward Seller, as the case may be, and shall not be on behalf of the Company.  Each of the Company, the General Partner and the Operating Partnership waives to the full extent permitted by applicable law any claims it may

35

have against the Underwriters, the Forward Seller or the Forward Purchaser arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

16.                  Counterparts .  This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

17.                  Applicable Law .  This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York without giving effect to any choice of law or conflicting provision or rule (whether of the State of New York, or of any other jurisdiction) that would cause the laws of any jurisdiction other than the State of New York to be applied.

18.                  Headings .  The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

19.                  Trial by Jury .  Each of the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates), the General Partner (on its behalf and, to the extent permitted by applicable law, on behalf of its sole trustee and affiliates) and the Operating Partnership (on its behalf and, to the extent permitted by applicable law, on behalf of its limited partners and affiliates) and each of the Underwriters, the Forward Seller and the Forward Purchaser hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the Transactions.

MATTERS TO BE ADDRESSED IN TAX OPINION OF

SKADDEN, ARPS, SLATE, MEAGHER & FLOM

1.               Commencing with its taxable year ended on December 31, 2013, CyrusOne has been organized and has operated in conformity with the requirements for qualification and taxation as a real estate investment trust (“ REIT ”) under the Code, and its proposed method of operation will enable it to meet the requirements for qualification and taxation as a REIT under the Code.

2.               Although the discussion set forth in the Prospectus under the heading “U.S. Federal Income Tax Considerations,” as supplemented by the discussion set forth in the Prospectus under the heading “Supplement to U.S. Federal Income Tax Considerations,” does not purport to discuss all possible U.S. Federal income tax consequences of the ownership and disposition of shares of Common Stock, such discussion, though general in nature, constitutes, in all material respects, a fair and accurate summary under current law of the material U.S. Federal income tax consequences of the ownership and disposition of shares of Common Stock, subject to the qualifications set forth therein.  The U.S. Federal income tax consequences of the ownership and disposition of shares of Common Stock by a holder will depend upon that holder’s particular situation, and we express no opinion as to the completeness of the discussion set forth in “U.S. Federal Income Tax Considerations” and “Supplement to U.S. Federal Income Tax Considerations” as applied to any particular holder.

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 Morgan Stanley & Co. LLC (“ Dealer ”) and CyrusOne 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 ”) and the 2006 ISDA Definitions (the “ Swap Definitions ”), as published by the International Swaps and Derivatives Association, Inc. (“ ISDA ”).  In the event of any inconsistency between the Equity Definitions and this Confirmation, this Confirmation will govern. 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 2002 ISDA Master Agreement (the “ ISDA Form ”), as published by ISDA, as if Dealer and Counterparty had executed the ISDA Form on the date hereof (but without any Schedule except for (i) the election of 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 election that the “Cross Default” provisions of Section 5(a)(vi) of the Agreement shall apply to Counterparty and Dealer, with a “Threshold Amount” of USD 50 million for Counterparty and a “Threshold Amount” equal to 3% of shareholders’ equity of Morgan Stanley, a Delaware corporation (“ MS Parent ”) as of the date hereof for Dealer; provided that (a) the phrase “or becoming capable at such time of being declared” shall be deleted from clause (1) of such Section 5(a)(vi) of the Agreement, (b) the following sentence shall be added to the end thereof: “Notwithstanding the foregoing, a default under subsection (2) hereof shall not constitute an Event of Default if (i) the default was caused solely by error or omission of an administrative or operational nature; (ii) funds were available to enable the party to make the payment when due; and (iii) the payment is made within three Local Business Days of such party’s receipt of written notice of its failure to pay.”; (c) the term “Specified Indebtedness” shall have the meaning specified in Section 14 of the Agreement, except that such term shall not include obligations in respect of deposits received in the ordinary course of a party’s banking business; and (iii) the elections set forth in Section 9 of this Confirmation.  All provisions contained in the Agreement are incorporated into and shall govern this Confirmation except as expressly modified herein.  This Confirmation evidences a complete and binding agreement between Dealer 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 Dealer or any of its Affiliates, including MS Parent (collectively, “ Morgan Stanley ”), and Counterparty or any confirmation or other agreement between Morgan Stanley and Counterparty pursuant to which an ISDA Master Agreement is deemed to exist between Morgan Stanley and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any

other agreement to which Morgan Stanley and Counterparty are parties, the Transaction shall not be considered a Transaction under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

(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 Dealer 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 Dealer, 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 take, or permit to be taken, any action to cause any “restricted period” (as such term is defined in Regulation M promulgated under the Exchange Act (“ Regulation M ”)) to occur 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 Dealer of such public announcement; (ii) promptly notify Dealer following any such

17

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 Dealer 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 Dealer 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 Dealer that such information is true and correct.  In addition, Counterparty shall promptly notify Dealer of the earlier to occur of the completion of such transaction and the completion of the vote by target shareholders.  Counterparty acknowledges that under the terms of this Confirmation, any such notice may result in a Regulatory Disruption, a Trading Condition or an Early Valuation or may affect the length of any ongoing Unwind Period; accordingly, Counterparty acknowledges that its delivery of such notice shall comply with the standards set forth in Section 6(c) above.  “ Merger Transaction ” means any merger, acquisition or similar transaction involving a recapitalization with respect to the Counterparty and/or the Shares as contemplated by Rule 10b-18(a)(13)(iv) under the Exchange Act.

(h)          Counterparty represents and warrants to, and agrees with, Dealer that Counterparty has not and will not, without the prior written consent of Dealer, enter into any structured share purchase or sale transaction (including the purchase or sale of any option or combination of options relating to the Shares), or any other transaction similar to the Transaction described herein, where any valuation period (however defined) in such other transaction will overlap at any time (including as a result of acceleration, postponement or extension in such valuation period as provided in the relevant agreement) with any Unwind Period under this Confirmation.  In the event that the valuation period in any such other transaction overlaps with any Unwind Period under this Confirmation as a result of any acceleration, postponement or extension of such Unwind Period, Counterparty shall promptly amend such transaction to avoid any such overlap.

(i)              Counterparty agrees to provide Dealer at least 10 Scheduled Trading Days’ written notice prior to any amendment, supplement, waiver or other modification to the Charter, bylaws or any other constitutive document of Counterparty that would reduce the ownership threshold set forth in Section 7.2.1 of the Charter to a percentage lower than 9.8% or that would, based on the advice of counsel to Counterparty, give rise to any other Applicable Restriction (as defined below) applicable to Dealer (including with respect to its commercially reasonable Hedge Positions) with respect to the Transaction (a “ Charter Notice ”). Upon receipt of a Charter Notice, Dealer may designate an Additional Termination Event with respect to any portion of the Transaction as the sole Affected Transaction with Counterparty as the sole Affected Party, that Dealer (or its affiliate), reasonably determines, based on advice of counsel,  is necessary to reduce the Charter Percentage to (i) the lowest ownership level contemplated by Section  7.2.1 of the Charter (or, if lower, the ownership level contemplated in any such other Applicable Restriction) minus (ii) 0.5%. The “ Charter Percentage ” shall be a fraction, the numerator of which is (i) the relevant Number of Shares plus (ii) any other Shares that Dealer, its affiliates and each other person  subject to aggregation of Shares with Dealer under the Charter (or such other Applicable Restriction) reasonably determines, based on advice of counsel, may be “Beneficially Owned” (howsoever defined) under the Charter (or such other Applicable Restriction), and the denominator of which is the number of Shares outstanding.

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 Dealer (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 Dealer, 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)  Dealer 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 Dealer 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

18

or shall be deemed to limit Dealer’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 Dealer’s rights in respect of any transaction other than the Transaction.

(b)          [Reserved.]

(c)           The parties hereto intend for:

(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 Dealer 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 5,000,000 Shares  (as adjusted for stock splits and similar events) (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 Counterparty’s control, (y) Merger Events requiring corporate action of Counterparty (or any surviving entity of the Issuer hereunder in connection with any such Merger Event) and (z) Announcement Events that are not outside Counterparty’s control.  Counterparty represents and warrants to Dealer (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 Dealer 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, shall deliver such Shares thereafter.

19

Counterparty shall not, until Counterparty’s Share delivery obligations under the Transaction have been satisfied in full, use any Shares that become available for potential delivery to Dealer 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 Dealer under the Transaction.

(e)           The parties intend for this Confirmation to constitute a “Contract” as described in the letter dated October 6, 2003 submitted on behalf of Goldman, Sachs &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 Dealer at 1585 Broadway, New York, New York 10036, Telephone No. (212) 761-3778, Facsimile No. (212) 212-507-4629

9.                                       [INTENTIONALLY OMITTED]

10.                                Beneficial Ownership .  Notwithstanding anything to the contrary in the Agreement or this Confirmation, in no event shall Dealer be entitled to receive, or be deemed to receive, Shares to the extent that, upon such receipt of such Shares, (i) the “beneficial ownership” (within the meaning of Section 13 of the Exchange Act and the rules promulgated thereunder) of Shares by Dealer, any of its affiliates’ business units subject to aggregation with Dealer 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 Dealer with respect to “beneficial ownership” of any Shares (collectively, “ MS Group ”) would be equal to or greater than 9.0% of the outstanding Shares (an “ Excess Section 13 Ownership Position ”), (ii) violation would occur in respect of any restriction on ownership and/or transfers set forth in Section 7.2.1 of the Charter or (iii) Dealer, MS Group or any person whose ownership position would be aggregated with that of Dealer or MS Group (Dealer, MS Group or any such person, a “ MS Person ”) under Sections 3-601 to 3-605 and 3-701 to 3-710 of the Maryland General Corporation Law or any state or federal bank holding company or banking laws, or any federal, state or local laws, regulations or regulatory orders or organizational documents or contracts of Counterparty, in each case, applicable to ownership of Shares (“ Applicable Restrictions ”), 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 Share that would be permitted under Applicable Restrictions 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 MS Person under Applicable Restrictions 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 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 (iii), an “ Excess Regulatory Ownership Position ”).  If any delivery owed to Dealer 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, Dealer gives notice to Counterparty that such delivery would not result in (x) MS Group directly or indirectly so beneficially owning in excess of 9.0% of the outstanding Shares and (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, Dealer 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

20

structure of the Transaction and all materials of any kind, including opinions or other tax analyses, provided by Dealer and its affiliates to Counterparty relating to such tax treatment and tax structure and (ii) Dealer does not assert any claim of proprietary ownership in respect of any description 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.                                Use of Shares .  Dealer acknowledges and agrees that, except in the case of a Private Placement Settlement, Dealer (or its agents or affiliates, as applicable) shall use any Shares delivered by Counterparty to Dealer on any Settlement Date to return to securities lenders to close out borrowings created by Dealer (or its agents or affiliates, as applicable) in connection with its hedging activities related to exposure under this Transaction or in a manner that Dealer otherwise believes in good faith and based on the advice of counsel to be in compliance with applicable securities law.

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

14.                                Set-Off.   Notwithstanding Section 6(f) of the Agreement, Dealer agrees not to set off or net amounts due from Counterparty with respect to any Transaction against amounts due from Dealer 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 Dealer 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.

15.                                Staggered Settlement .  Notwithstanding anything to the contrary herein, Dealer 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.

16.                                Special Dividends .  If an ex-dividend date for a Special Dividend occurs on or after the Trade Date and on or prior to the Maturity Date (or, if later, the last date on which Shares are delivered by Counterparty to Dealer in settlement of the Transaction), Counterparty shall pay to Dealer on the earlier of (i) the date on which such Special Dividend is paid by the Issuer to holders of record of the Shares and (ii) the Maturity Date an amount, as determined by the Calculation Agent, in cash equal to the product of (a) the per Share amount of such Special Dividend, and (b) the Remaining Amount on such ex-dividend date.  “ Special Dividend ” means any cash dividend or distribution declared by the Issuer with respect to the Shares that is specified by the board of directors of the Issuer as an “extraordinary” dividend.  “ Remaining Amount ” means, at any time, the sum of (i) the number of Remaining Shares as of such time and (ii) if the Net Share Settlement Amount as of such time is (A) a positive number and (B) has not been delivered by Counterparty to Dealer pursuant to “Net Share Settlement” above, such Net Share Settlement Amount.

17.                                Waiver of Jury Trial . EACH PARTY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE AGREEMENT, THIS CONFIRMATION, ANY TRANSACTION HEREUNDER AND/OR ALL MATTERS ARISING IN CONNECTION WITH THE AGREEMENT, THIS CONFIRMATION AND/OR ANY TRANSACTION HEREUNDER.  EACH PARTY (I) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF SUCH A SUIT, ACTION OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTY HAVE BEEN INDUCED TO ENTER INTO THE TRANSACTIONS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS PROVIDED HEREIN.

21

18.                                Submission to Jurisdiction .  13(b) of the Agreement is deleted in its entirety and replaced by the following:

Nothing in the Confirmation or this Agreement precludes either party from bringing Proceedings in any other jurisdiction if (A) the courts of the State of New York or the United States of America for the Southern District of New York lack jurisdiction over the parties or the subject matter of the Proceedings or declines to accept the Proceedings on the grounds of lacking such jurisdiction; (B) the Proceedings are commenced by a party for the purpose of enforcing against the other party’s property, assets or estate any decision or judgment rendered by any court in which Proceedings may be brought as provided hereunder; (C) the Proceedings are commenced to appeal any such court’s decision or judgment to any higher court with competent appellate jurisdiction over that court’s decisions or judgments if that higher court is located outside the State of New York or Borough of Manhattan, such as a federal court of appeals or the U.S. Supreme Court; or (D) any suit, action or proceeding has been commenced in another jurisdiction by or against the other party or against its property, assets or estate and, in order to exercise or protect its rights, interests or remedies under this Agreement or the Confirmation, the party (1) joins, files a claim, or takes any other action, in any such suit, action or proceeding, or (2) otherwise commences any Proceeding in that other jurisdiction as the result of that other suit, action or proceeding having commenced in that other jurisdiction.”

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.                                Taxes .

(i)                                      For the purpose of Section 3(f) of the Agreement, Dealer makes the following representations: (1) it is a disregarded entity and its sole owner is a “U.S. person” (as that term is used in Section 1.1441-4(a)(3)(ii) of the United States Treasury Regulations (the “ Treasury Regulations ”)) for U.S. federal income tax purposes and (2) Dealer’s sole member is a corporation duly organized under the laws of the State of Delaware and is an exempt recipient under Treasury Regulations Section 1.6049-4(c)(1)(ii).

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 Dealer (or any affiliate of Dealer designated by Dealer) 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, Dealer and any potential purchaser of any such shares from Dealer (or any affiliate of Dealer designated by Dealer) identified by Dealer 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 issuers comparable to Counterparty (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 Dealer. (or any affiliate of Dealer designated by Dealer) in connection with the private placement of such shares by Counterparty to Dealer (or any such affiliate) and the private resale of such shares by Dealer (or any such affiliate), substantially similar to private placement purchase agreements customary for private placements of equity securities, in form and substance commercially reasonably satisfactory to Dealer, 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, Dealer and its affiliates and the provision of customary opinions, accountants’ comfort letters and lawyers’ negative assurance letters, and shall provide for the payment by Counterparty of all reasonable fees and expenses in connection with such resale, including all reasonable fees and expenses of counsel for Dealer, 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 Dealer (or any such affiliate) and the private resale of such shares by Dealer (or any such affiliate), Counterparty shall, if so requested by Dealer, prepare, in cooperation with Dealer, a private placement memorandum in form and substance reasonably satisfactory to Dealer.

In connection with the foregoing, Dealer acknowledges and agrees that a Private Placement Agreement and private placement memorandum substantially similar to the Underwriting Agreement and prospectus used in connection with the public offering of Shares pursuant thereto (with such modifications thereto as are reasonably satisfactory to Dealer taking into account the exempt resale of the Unregistered Settlement Shares, then-current facts and circumstances and such other factors as Dealer determines appropriate in good faith and its reasonable discretion, including with respect to any legal, regulatory or self-regulatory requirements or related policies and procedures generally applicable in similar situations and applied in a non-discriminatory manner (whether or not such requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer)), respectively, shall satisfy the documentation requirements set forth in clauses (c) and (d) above.

In the case of a Private Placement Settlement, Dealer shall, in its good faith discretion, adjust the amount of Unregistered Settlement Shares to be delivered to Dealer hereunder in a commercially reasonable manner to reflect the fact that such Unregistered Settlement Shares may not be freely returned to securities lenders by Dealer and may only be saleable by Dealer 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 Dealer 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 Dealer (or such affiliate of Dealer) to Counterparty or such transfer agent of seller’s and broker’s representation letters customarily delivered by Dealer 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 Dealer (or such affiliate of Dealer).
