Unless otherwise agreed upon and subject to any exceptions permitted or contemplated by the Indenture or the Security Agreements, the Representative and the Notes Collateral Agent shall have received (i) UCC financing statements (or the equivalent filing in each other jurisdiction of the Issuer or Guarantor required to be made on the Closing Date) necessary to perfect the security interests in the Collateral (to the extent such security interests can be perfected by filing) for the benefit of the Notes Collateral Agent, the Trustee and the holders of the Securities, in form for filing in the appropriate jurisdictions, and (ii) intellectual property security agreements in form for filing in the USPTO or the USCO, as applicable, in order to perfect the security interests in the intellectual property which is part of the Collateral for the benefit of the Notes Collateral Agent, the Trustee and the holders of the Securities, in each case, with the priority required by the Security Agreements.

(s)Lien Searches. The Representative shall have received certified copies of Uniform Commercial Code tax and judgment lien searches or equivalent reports or searches listing all effective financing statements, lien notices or comparable documents that name the Issuer or any Guarantor as debtor, none of which encumber the Collateral covered or intended to be covered by the Security Agreements (other than Permitted Liens).

(t)Stock Certificates. Certificates representing all of the capital stock of the Issuer’s subsidiaries, to the extent certificated and required to be pledged as Collateral under the Security Agreements shall have been delivered to the New Credit Facility Agent, as required by the Security Agreements and subject to the terms of the Intercreditor Agreement and any exceptions permitted or contemplated by the Indenture and the Security Agreements. The Initial Purchasers hereby acknowledge the satisfaction of this Section 6(u).

(u)Additional Documents. On or prior to the Closing Date, the Issuer shall have furnished to the Initial Purchasers such further certificates and documents as the Initial Purchasers may reasonably request.

All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers.

7.     Indemnification and Contribution.

(a)Indemnification of the Initial Purchasers. The Issuer and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Initial Purchaser, its affiliates, directors and officers and each person, if any, who controls such Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses reasonably incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Circular, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Circular (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser furnished to the Issuer in writing by such Initial Purchaser through the Representative expressly for use therein as set forth in paragraph (b) below.

(b)Indemnification of the Issuer and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Issuer and each of the Guarantors, each of the Issuer’s and the Guarantors’ respective directors and officers and each person, if any, who controls the Issuer or the Guarantors, in each case, within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Issuer in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Circular, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Circular (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the following: the first sentence of the fourth paragraph, the second and third sentences of the fifth paragraph, and the statements set forth in the eighth paragraph under the heading “Plan of Distribution” in the Preliminary Offering Circular and the Offering Circular.

(c)Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification

pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by the Representative and any such separate firm for the Issuer, the Guarantors, their respective directors and officers and any control persons of the Issuer and the Guarantors shall be designated in writing by the Issuer. The Indemnifying Person 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 Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement unless such Indemnifying Person has (a) paid all undisputed amounts and only failed to pay amounts disputed in good faith and (b) provided detail regarding the reasons for the failure to pay amounts requested by the Indemnifying Person. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)Contribution. If the indemnification provided for in the above paragraphs (a) or (b) of this Section 7 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Issuer from the sale of the Securities and the commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Issuer and the Guarantors on the one hand and the Initial Purchasers on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue

statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuer or any Guarantor or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)Limitation on Liability. The Issuer and the Guarantors, and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser 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 Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f)Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8.     Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Issuer, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the Nasdaq Stock Market; (ii) trading of any securities issued or guaranteed by MultiPlan Corporation, the Issuer or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Circular.

9.     Defaulting Initial Purchaser.

(a)If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Issuer on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Issuer shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the nondefaulting Initial Purchasers or the Issuer may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Issuer or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Circular or in any other document or arrangement, and the Issuer agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Circular that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in

Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b)If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuer as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Issuer shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c)If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuer as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Issuer shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Issuer or the Guarantors, except that the Issuer and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

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

10.    Payment of Expenses.

(a)Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Issuer and each of the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Circular, any other Time of Sale Information, any Issuer Written Communication and the Offering Circular (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Issuer’s and the Guarantors’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Initial Purchasers may designate and the preparation, printing and distribution of a Blue Sky memorandum (including the related reasonable fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee, the Notes Collateral Agent and any paying agent (including related reasonable fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with the approval of the Securities for book-entry transfer by DTC; (ix) costs relating to the creation, documentation or perfection of liens on the Collateral, including reasonable fees and expenses of counsel to the Initial Purchasers in connection with the creation, documentation or perfection of such liens; and (x) all expenses incurred by the Issuer and the Guarantors in connection with any “road show” presentation to potential investors; provided in the case of this clause (x) (A) the Initial Purchasers shall pay their own travel costs and expenses in connection with any “road show” and (B) the cost of any chartered aircraft used by the Issuer in connection with any “road show” presentation shall be borne 50% by the Issuer and 50% by the Initial Purchasers.

(b)If (i) this Agreement is terminated pursuant to Section 8, (ii) the Issuer for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to

purchase the Securities for any reason permitted under this Agreement (except that if this Agreement is terminated pursuant to Section 9, the fees and expenses of any defaulting Initial Purchaser need not be reimbursed), the Issuer agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.

11.    Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of each Initial Purchaser referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.

12.    Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of (a) the Issuer and the Guarantors and (b) the Initial Purchasers contained in this Agreement or made by or on behalf of the Issuer, the Guarantors or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Issuer, the Guarantors or the Initial Purchasers.

13.    Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act.

14.    Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Initial Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Issuer, which information may include the name and address of their respective clients, as well as other information that will allow the Initial Purchasers to properly identify their respective clients.

15.    Recognition of the U.S. Special Resolution Regimes. In the event that any Initial Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Initial Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

In the event that any Initial Purchaser that is a Covered Entity or a BHC Act Affiliate of such Initial Purchaser becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Initial Purchaser are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section 15, the following definitions apply:

16.    Miscellaneous.

(a)Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by the Representative on behalf of the Initial Purchasers, and any such action taken by the Representative shall be binding upon the Initial Purchasers.

Notices to the Initial Purchasers shall be given to the Representative: c/o Goldman Sachs & Co. LLC, 200 West Street, New York, NY 10282, Attention: Registration Department. Notices to the Issuer and the Guarantors shall be given to them c/o MultiPlan Corporation, 115 Fifth Avenue New York, NY 10003; Attention: Chief Financial Officer.

(c)Entire Agreement. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof.

(d)Governing Law. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the laws of the State of New York. The Issuer and each of the Guarantors agree that any suit or proceeding arising in respect of this Agreement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Issuer and each of the Guarantors agree to submit to the jurisdiction of, and to venue in, such courts.

(e)Waiver of Jury Trial. Each of the parties hereto hereby irrevocably waives any right to trial by jury in any suit or proceeding arising out of or relating to this Agreement.

This Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

    Title: Managing Director

1.    Pricing Supplement containing the terms of the Securities, substantially in the form of Exhibit A.

ANY DISCLAIMERS OR OTHER NOTICES THAT MAY APPEAR BELOW ARE NOT APPLICABLE TO THIS COMMUNICATION AND SHOULD BE DISREGARDED. SUCH DISCLAIMERS OR OTHER NOTICES WERE AUTOMATICALLY GENERATED AS A RESULT OF THIS COMMUNICATION BEING SENT VIA BLOOMBERG OR ANOTHER EMAIL SYSTEM.

In connection with offers and sales of Securities outside the United States:

(a)    Each Initial Purchaser acknowledges that the Securities have not been registered under the Securities Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except pursuant to an exemption from, or in transactions not subject to, the registration requirements of the Securities Act.

(b)    Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that:

    (i)    Such Initial Purchaser has offered and sold the Securities, and will offer and sell the Securities, (A) as part of their distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering of the Securities and the Closing Date, only in accordance with Regulation S under the Securities Act (“Regulation S”) or Rule 144A or any other available exemption from registration under the Securities Act.

    (ii)    (A) Neither such Initial Purchaser nor any of its affiliates or any person acting on its or their behalf has engaged or will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Securities, (B) such Initial Purchaser has not entered and will not enter into any contractual arrangement with any distributor (within the meaning of Regulation S) with respect to the distribution of the Securities, except with its affiliates and (C) such Initial Purchaser and its affiliates and any person acting on its behalf have complied and will comply with the offering restrictions requirement of Regulation S.

    (iii)    At or prior to the confirmation of sale of any Securities sold in reliance on Regulation S, such Initial Purchaser will have sent to each distributor, dealer or other person receiving a selling concession, fee or other remuneration that purchases Securities from it during the distribution compliance period (within the meaning of Regulation S) a confirmation or notice to substantially the following effect:

(c)    Each Initial Purchaser acknowledges that no action has been or will be taken by the Issuer that would permit a public offering of the Securities, or possession or distribution of any of the Time of Sale Information, the Offering Circular, any Issuer Written Communication or any other offering or publicity material relating to the Securities, in any country or jurisdiction where action for that purpose is required.

(d)    Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that:

    (i)    it has only communicated or caused to be communicated and will only communicate or cause to be communicated any invitation or inducement to engage in investment

activity (within the meaning of Section 21 of the United Kingdom Financial Services and Markets Act 2000 (the “FSMA”)) received by it in connection with the issue or sale of any Securities in circumstances in which Section 21(1) of the FSMA does not apply to the Issuer or the Guarantors; and
