Ladies and Gentlemen:

Cooper-Standard Holdings Inc., a Delaware corporation (the “Company”) hereby confirms its agreement with you (the “Initial Purchasers”), as set forth below.

Section 1. The Securities. Subject to the terms and conditions herein contained, the Company proposes to issue and sell to the Initial Purchasers $25,000,000 aggregate principal amount of its Senior PIK Toggle Notes due 2018 (the “Notes”). The Notes are to be issued under that certain indenture (the “Indenture”) dated as of April 3, 2013, by and between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Notes will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “DTC”).

The Company previously issued $175,000,000 aggregate principal amount of its Senior PIK Toggle Notes due 2018 under the Indenture (the “Existing Notes”). The Notes constitute an issuance of “Additional Securities” under the Indenture. Except as otherwise described in the Pricing Disclosure Package (as defined below), the Notes will have identical terms to the Existing Notes and will be treated as a single class of notes for all purposes under the Indenture. The Notes will have the same CUSIP and ISIN numbers as, and will trade fungibly with, the Existing Notes (except that the Notes issued pursuant to Regulation S (as defined below) will trade separately under different CUSIP and ISIN numbers until at least 40 days after the issue date of the Notes).

This Agreement, the Notes and the Indenture, as entered into by the Company, are hereinafter referred to as the “Transaction Documents.”

The Notes will be offered and sold to the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the “Act”), in reliance on exemptions therefrom.

In connection with the sale of the Notes, the Company has prepared a preliminary offering memorandum dated May 13, 2013 (including the information incorporated by reference therein, the “Preliminary Memorandum”) setting forth or including a description of the terms of the Notes, the terms

of the offering of the Notes, a description of the Company and any material developments relating to the Company occurring after the date of the most recent historical financial statements included (or incorporated by reference) therein. As used herein, “Pricing Disclosure Package” shall mean the Preliminary Memorandum, as supplemented or amended by the written communications listed on Schedule 2 hereto in the most recent form that has been prepared and delivered by the Company to the Initial Purchasers in connection with their solicitation of offers to purchase Notes prior to the time when sales of the Notes were first made (the “Time of Execution”). Promptly after the Time of Execution and in any event no later than the second Business Day following the Time of Execution, the Company will prepare and deliver to each Initial Purchaser a final offering memorandum (including the information incorporated by reference therein, the “Final Memorandum”), which will consist of the Preliminary Memorandum with such changes therein as are required to reflect the information contained in the amendments or supplements listed on Schedule 2 hereto. The Company hereby confirms that it has authorized the use of the Pricing Disclosure Package, the Final Memorandum and any Recorded Road Show (as defined below) in connection with the offer and sale of the Notes by the Initial Purchasers.

Section 2. Representations and Warranties. As of the Time of Execution and at the Closing Date, the Company represents and warrants to and agrees with each of the Initial Purchasers as follows (references in this Section 2 to the “Offering Memorandum” are to (i) the Pricing Disclosure Package in the case of representations and warranties made as of the Time of Execution and (ii) both the Pricing Disclosure Package and the Final Memorandum in the case of representations and warranties made at the Closing Date):

(a) The Preliminary Memorandum, on the date thereof, did not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. At the Time of Execution, the Pricing Disclosure Package does not, and the Final Memorandum as of its date (as amended or supplemented in accordance with Section 5(a)) and on the Closing Date (as defined in Section 3 below) will not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company does not make any representation or warranty as to the information contained in or omitted from the Pricing Disclosure Package and Final Memorandum in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of the Initial Purchasers through Deutsche Bank Securities Inc. (“DBSI”) specifically for inclusion therein, as described in Section 12 hereof. The Company has neither distributed nor referred to and will not distribute or refer to any written communications (as defined in Rule 405 of the Act) that constitutes an offer to sell or solicitation of an offer to buy the Notes (each such communication by the Company or its agents and representatives (other than the Pricing Disclosure Package and Final Memorandum), an “Issuer Written Communication”) other than the Pricing Disclosure Package, the Final Memorandum and the recorded electronic road show made available to investors, if any (the “Recorded Road Show”). Any information in an Issuer Written Communication that is not otherwise included in the Pricing Disclosure Package and the Final Memorandum does not conflict with the Pricing Disclosure Package or the Final Memorandum, and each Issuer Written Communication, when taken together with the Pricing Disclosure Package does not at the Time of Execution and when taken together with the Final Memorandum at the Closing Date will not, contain 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 under which they were made, not misleading.

(b) As of the Closing Date, the Company will have the authorized, issued and outstanding capitalization set forth in the Offering Memorandum under the heading “Capitalization”; all of the subsidiaries of the Company are listed in Annex A attached hereto (each, a “Subsidiary”

-2-

and collectively, the “Subsidiaries”); all of the outstanding shares of capital stock of the Company and the Subsidiaries have been, and as of the Closing Date will be, duly authorized and validly issued, are fully paid and nonassessable (except as such nonassessability may be affected by Sections 18-607 and 18-804 of the Delaware Limited Liability Company Act) and were not issued in violation of any preemptive or similar rights; except as set forth in the Pricing Disclosure Package and the Final Memorandum, all of the outstanding shares of capital stock of the Company and of each of the Subsidiaries will be free and clear of all liens, encumbrances, equities and claims or restrictions on transferability or voting (other than those imposed by the Act and the securities or “Blue Sky” laws of certain jurisdictions). Except as set forth in the Offering Memorandum, there are no (i) options, warrants or other rights to purchase, (ii) agreements or other obligations to issue or (iii) other rights to convert any obligation into, or exchange any securities for, shares of capital stock of or ownership interests in the Company or any of the Subsidiaries outstanding.

(d) The Company has all requisite corporate power and authority to execute, deliver and perform each of its obligations under the Notes. The Notes, when issued, will be in the form contemplated by the Indenture.

(e) The Company has all requisite corporate power and authority to perform its obligations under the Indenture and, as of the date of execution thereof, the Company had all requisite corporate power and authority to execute, deliver and perform its obligations under the Indenture.

(a) Until the later of (i) the completion of the distribution of the Notes by the Initial Purchasers and (ii) the Closing Date, the Company will not amend or supplement the Pricing Disclosure Package and the Final Memorandum or otherwise distribute or refer to any written communication (as defined under Rule 405 of the Act) that constitutes an offer to sell or a solicitation of an offer to buy the Notes (other than the Pricing Disclosure Package, any Recorded Road Show and the Final Memorandum) or file any report with the Commission under the Exchange Act unless the Initial Purchasers shall previously have been advised and furnished a copy for a reasonable period of time prior to the proposed amendment, supplement or report.

(b) The Company will cooperate with the Initial Purchasers in arranging for the qualification of the Notes for offering and sale under the securities or “Blue Sky” laws of such jurisdictions as the Initial Purchasers may designate and will continue such qualifications in effect for as long as may be necessary to complete the resale of the Notes; provided, however, that in connection therewith, the Company shall not be required to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction or subject itself to taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject.

(c) If, at any time prior to later of the Closing Date and the completion of the sale by the Initial Purchasers of the Notes, any event occurs or information becomes known as a result of which the Pricing Disclosure Package and the Final Memorandum as then amended or supplemented would include any untrue statement of a material fact, or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or any Issuer Written Communication would conflict with the Pricing Disclosure Package as then amended or supplemented, or if for any other reason it is necessary at any time to amend or supplement by Issuer Written Communication, the Pricing Disclosure Package and the Final Memorandum to comply with applicable law, the Company will promptly notify the Initial Purchasers thereof and will prepare, at its own expense, an amendment or supplement to any of the Pricing Disclosure Package or any Issuer Written Communication (it being understood that any such amendments or supplements may take the form of an amended or supplemented Final Memorandum) as may be necessary so that the statements in any of the Pricing Disclosure Package as so amended or supplemented will not, in light of the circumstances under which they were made, be misleading or so that any Issuer Written Communication will not conflict with the Pricing Disclosure Package or so that the Pricing Disclosure Package or any Issuer Written Communication as so amended or supplemented will comply with law.

(d) The Company will, without charge, provide to the Initial Purchasers and to counsel for the Initial Purchasers as many copies of the Pricing Disclosure Package, any Issuer Written Communication and the Final Memorandum (including, any amendment or supplement thereto and documents incorporated by reference therein) as the Initial Purchasers may reasonably request.

(e) The Company will apply the net proceeds from the sale of the Notes as set forth under “Use of Proceeds” in the Pricing Disclosure Package and the Final Memorandum.

(f) None of the Company or any of its Affiliates will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any “security” (as defined in the Act) that could be integrated with the sale of the Notes in a manner which would require the registration under the Act of the Notes.

(g) The Company will not, and will not permit any of its Affiliates or persons acting on their behalf to, engage in any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) in connection with the offering of the Notes or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Act.

(h) For so long as any of the Notes remain outstanding, the Company will make available at its expense, upon request, to any holder of such Notes and any prospective purchasers thereof the information specified in Rule 144A(d)(4) under the Act, unless the Company is then subject to Section 13 or 15(d) of the Exchange Act.

(i) The Company will use its commercially reasonable efforts to permit the Notes to be eligible for clearance and settlement through The Depository Trust Company.

(j) During the period beginning on the date hereof and continuing to the date that is 90 days after the Release Date, without the prior written consent of DBSI, the Company will not offer, sell, contract to sell or otherwise dispose of, except as provided hereunder, any debt securities of the Company that are substantially similar to the Notes.

(k) In connection with Notes offered and sold in an offshore transaction (as defined in Regulation S), the Company will not register any transfer of such Notes not made in accordance with the provisions of Regulation S or will, except in accordance with the provisions of Regulation S, if applicable, issue any such Notes in the form of definitive securities.

(l) Neither the Company nor any of its Affiliates will engage in any directed selling efforts (as that term is defined in Regulation S) with respect to the Notes.

(m) For a period of one year (calculated in accordance with paragraph (d) of Rule 144 under the Act) following the Closing Date, the Company will not, and will use its reasonable best efforts not to permit any of its subsidiaries to, resell any Notes are acquired by the Company or any of its subsidiaries, except for Notes purchased by the Company or any of its subsidiaries and resold in a transaction registered under the Act.

printing the Pricing Disclosure Package and the Final Memorandum and any amendment or supplement thereto, and any “Blue Sky” memoranda, (ii) all arrangements relating to the delivery to the Initial Purchasers of copies of the foregoing documents, (iii) the fees and disbursements of the counsel, the accountants and any other experts or advisors retained by the Company, (iv) preparation (including printing), issuance and delivery to the Initial Purchasers of the Notes, (v) the qualification of the Notes under state securities and “Blue Sky” laws, including filing fees and reasonable fees and disbursements of counsel for the Initial Purchasers in connection with the production of the Blue Sky Memorandum, (vi) expenses in connection with the “roadshow” and any other meetings with prospective investors in the Notes (provided, however, that the Company and the Initial Purchasers shall each agree to pay for 50% of the cost of any aircraft chartered in order to transport representatives of the Company and the Initial Purchasers to meetings with prospective investors in the Notes), (vii) fees and expenses of the Trustee including reasonable and documented fees and expenses of counsel and (viii) any fees charged by investment rating agencies for the rating of the Notes. If the sale of the Notes provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 7 hereof is not satisfied, because this Agreement is terminated or because of any failure, refusal or inability on the part of the Company to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder (other than solely by reason of a default by the Initial Purchasers of their obligations hereunder after all conditions hereunder have been satisfied in accordance herewith), the Company agrees to promptly reimburse the Initial Purchasers upon demand for all reasonable and documented out-of-pocket expenses (including reasonable fees, disbursements and charges of Cahill Gordon & Reindel LLP, counsel for the Initial Purchasers) that shall have been reasonably incurred by the Initial Purchasers in connection with the proposed purchase and sale of the Notes.

(b) Each of the Initial Purchasers represents and warrants (as to itself only) with respect to offers and sales outside the United States that (i) it has and will comply with all applicable laws and regulations in each jurisdiction in which it acquires, offers, sells or delivers Notes or has in its possession or distributes any Pricing Disclosure Package or Final Memorandum or any such other material, in all cases at its own expense; (ii) the Notes have not been and will not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with Regulation S under the Act or pursuant to an exemption from the registration requirements of the Act; and (iii) it has offered

(a) The Company agrees to indemnify and hold harmless each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which any Initial Purchaser or such controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon the following:

(i) any untrue statement or alleged untrue statement of any material fact contained in the Pricing Disclosure Package, any Issuer Written Communication or the Final Memorandum or any amendment or supplement thereto; or

(ii) the omission or alleged omission to state, in the Pricing Disclosure Package, any Issuer Written Communication or the Final Memorandum or any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein not misleading;

and will reimburse, as incurred, the Initial Purchasers and each such controlling person for any legal or other expenses incurred by the Initial Purchasers or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Pricing Disclosure Package or Final Memorandum or any amendment or supplement thereto in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to the Company by DBSI specifically for use therein. The indemnity provided for in this Section 9 will be in addition to any liability that the Company may otherwise have to the indemnified parties. The Company shall not be liable under this Section 9 for any settlement of any claim or action effected without its prior written consent, which shall not be unreasonably withheld.

(b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Pricing Disclosure Package, any Issuer Written Communication or the Final Memorandum or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated in the Pricing Disclosure Package, any Issuer Written Communication or the Final Memorandum or any amendment or supplement thereto, or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser, furnished

-16-

to the Company by DBSI specifically for use therein; and subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any legal or other expenses incurred by the Company or any such director, officer or controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. The indemnity provided for in this Section 9 will be in addition to any liability that the Initial Purchasers may otherwise have to the indemnified parties. The Initial Purchasers shall not be liable under this Section 9 for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld.

(c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 9, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchasers in the case of paragraph (a) of this Section 9 or the Company in the case of paragraph (b) of this Section 9, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. All fees and expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 9, in which case the indemnified party may effect such a settlement without such consent. No indemnifying party shall, without the prior written consent of the indemnified party, effect any

-17-

settlement or compromise of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party, or indemnity could have been sought hereunder by any indemnified party, unless such settlement (A) includes an unconditional written release of the indemnified party, in form and substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 9 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company on the one hand and any Initial Purchaser on the other shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by such Initial Purchaser. The relative fault of the parties 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 on the one hand, or such Initial Purchaser on the other, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Company and the Initial Purchasers agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each director of the Company, each officer of the Company and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company.

Section 10. Survival Clause. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Company, its officers and the Initial Purchasers set forth in this Agreement or made by or on behalf of them pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Company, any of its officers or directors, the Initial Purchasers or any controlling person referred to in Section 9 hereof and (ii) delivery of and payment for the Notes. The respective agreements, covenants, indemnities and other statements set forth in Sections 6, 9, 10 and 15 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement; provided, however, that if the purchase of the Notes by the Initial Purchasers is not consummated as a result of the occurrence or happening of an event described

-18-

in clause (a)(ii), (iii) or (iv) of Section 11 hereof, the Company shall have no obligation to pay for any expenses (including fees and disbursements of counsel) incurred by the Initial Purchasers in connection with the offering of the Notes.

Section 11. Termination.

(a) This Agreement may be terminated in the discretion of the Initial Purchasers by written notice to the Company given prior to the Closing Date in the event that the Company shall have failed, refused or been unable to perform all obligations and satisfy all conditions on its part to be performed or satisfied hereunder at or prior thereto, if not waived by the Initial Purchasers, or, if at or prior to the Closing Date,

(ii) trading in securities on the New York Stock Exchange shall have been suspended or materially limited or minimum or maximum prices shall have been established on any such exchange or market;

(iii) a banking moratorium shall have been declared by New York or United States authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred;

(iv) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power, or (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or any other calamity or emergency involving the United States, or (C) any material change in the financial markets of the United States which, in the case of (A), (B) or (C) above and in the sole judgment of DBSI, makes it impracticable or inadvisable to proceed with the offering or the delivery of the Notes as contemplated by the Pricing Disclosure Package and the Final Memorandum; or

(v) any securities of the Company shall have been downgraded by any nationally recognized statistical rating organization or any such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its ratings of any securities of the Company (other than an announcement with positive implications of a possible upgrading).

(b) Termination of this Agreement pursuant to this Section 11 shall be without liability of any party to any other party except as provided in Section 10 hereof.
