At any time when the Company is not subject to Section 13 or 15(d) of the Exchange Act and the Offered Securities are outstanding, the Company will promptly furnish or cause to be furnished to CSFB and, upon request, to each of the other Purchasers and, upon request of holders and prospective purchasers of the Offered Securities, to such holders and purchasers, copies of the information required to be delivered to holders and prospective purchasers of the Offered Securities pursuant to Rule 144A(d)(4) under the Securities Act (or any successor provision thereto) in order to permit compliance with Rule 144A in connection with resales by such holders of the Offered Securities. The Company and the Guarantors will pay the expenses of printing and distributing to the Purchasers (and all such holders and prospective purchasers) all such documents. (c) The Company will arrange for the qualification of the Offered Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions in the United States as CSFB reasonably designates and will continue such qualifications in effect so long as required for the resale of the Offered Securities by the Purchasers, provided that neither the Company nor any of the Guarantors will be required to qualify as a foreign corporation or to file a general consent to service of process or to subject itself to taxation in any such jurisdiction. 12 (d) During the period of two years after the Closing Date or, if earlier until such time as the Offered Securities are no longer restricted securities (as defined in Rule 144 under the Securities Act), the Company will, upon request, furnish to CSFB, each of the Purchasers and any holder of Offered Securities a copy of the restrictions on transfer applicable to the Offered Securities. (e) During the period of two years after the Closing Date or, if earlier until such time as the Offered Securities are no longer restricted securities (as defined in Rule 144 under the Securities Act), the Company will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Offered Securities that have been reacquired by any of them. (f) To the extent that the Company's periodic reports under the Exchange Act are not readily available in the Commission's EDGAR system (or any successor thereto), or the Company no longer files periodic reports under Section 13 or 15(d) of the Exchange Act, during the period of five years hereafter, the Company will furnish to CSFB and, upon request, to each of the other Purchasers, as soon as practicable after the end of each fiscal year, a copy of its annual report to shareholders for such year; and the Company will furnish to CSFB and, upon request, to each of the other Purchasers (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to shareholders, and (ii) from time to time, such other information concerning the Company as CSFB may reasonably request. (g) During the period of two years after the Closing Date or, if earlier until such time as the Offered Securities are no longer restricted securities (as defined in Rule 144 under the Securities Act), the Company will not and the Guarantors will not be or become, an open-end investment company, unit investment trust or face-amount certificate company that is or is required to be registered under Section 8 of the Investment Company Act. (h) The Company will pay all expenses incidental to the performance of its obligations under this Agreement, the Indenture and the Registration Rights Agreement, including (i) the reasonable fees and expenses of the Trustee and its counsel; (ii) all expenses in connection with the execution, issue, authentication, packaging and initial delivery of the Offered Securities and, as applicable, the Exchange Securities, the preparation and printing of this Agreement, the Registration Rights Agreement, the Offered Securities, the Indenture, the Offering Document and amendments and supplements thereto, and any other document relating to the issuance, offer, sale and delivery of the Offered Securities and as applicable, the Exchange Securities; (iii) the cost of listing the Offered Securities and qualifying the Offered Securities for trading in The PortalSM Market ("PORTAL") and any expenses incidental thereto; (iv) the cost of any advertising approved by the Company in connection with the issue of the Offered Securities (v) for any reasonable expenses (including fees and disbursements of counsel) incurred in connection with qualification of the Offered Securities or the Exchange Securities for sale under the laws of such jurisdictions in the United States as CSFB reasonably designates and the printing of memoranda relating thereto; (vi) for any fees charged by investment rating agencies for the rating of the Securities or the Exchange Securities, and (vii) for expenses incurred in distributing preliminary offering circulars and the Offering Document (including any amendments and supplements thereto) to the Purchasers. The Company will also pay or 13 reimburse the Purchasers (to the extent incurred by them) for all travel expenses of the Purchasers and the Company's officers and employees and any other expenses of the Purchasers and the Company in connection with attending or hosting meetings with prospective purchasers of the Offered Securities from the Purchasers. (i) In connection with the offering, until CSFB shall have notified the Company and the other Purchasers of the completion of the resale of the Offered Securities, neither the Company nor any of its affiliates has or will, either alone or with one or more other persons, bid for or purchase for any account in which it or any of its affiliates has a beneficial interest any Offered Securities or attempt to induce any person to purchase any Offered Securities; and neither it nor any of its affiliates will make bids or purchases for the purpose of creating actual, or apparent, active trading in, or of raising the price of, the Offered Securities. (j) For a period of 90 days after the date of the initial offering of the Offered Securities by the Purchasers, the Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any United States dollar-denominated debt securities issued or guaranteed by the Company and having a maturity of more than one year from the date of issue except issuances of Exchange Securities pursuant to the Registration Rights Agreement, without the prior written consent of CSFB. The Company will not at any time offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any securities under circumstances where such offer, sale, pledge, contract or disposition would cause the exemption afforded by Section 4(2) of the Securities Act or the safe harbor of Regulation S thereunder to cease to be applicable to the offer and sale of the Offered Securities. (k) The Company will, concurrently with the issuance of the Offered Securities on the Closing Date, enter into a new senior credit facility (the "New Senior Credit Facility") and the New Senior Credit Facility will be in full force and effect on the Closing Date, and the New Senior Credit Facility will conform in all material respects to the description thereof contained in the Offering Document. 6. Conditions of the Obligations of the Purchasers. The obligations of the several Purchasers to purchase and pay for the Offered Securities will be subject to the accuracy of the representations and warranties on the part of the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors herein on the date hereof and on the Closing Date, to the accuracy of the statements of officers of the Company made in certificates made pursuant to the provisions hereof, to the performance by the Company and the Guarantors of their obligations hereunder and to the following additional conditions precedent: (a) On or prior to midnight on the date hereof, (i) the Company shall have caused PricewaterhouseCoopers LLP to have delivered a "comfort letter" to the Representative, dated the date hereof and addressed to the Purchasers and covering such matters as may be requested by them and in form and substance satisfactory to them in all respects, all as determined by the Representative in its sole discretion (it being understood that in no event will the comfort letter be less favorable than the draft delivered to Latham & Watkins LLP on March 21, 2003) and (ii) the Final Offering Circular shall have been finalized in form and substance satisfactory to the Representative in all respects, all as determined by the Representative in its sole 14 discretion, or at such other time not later than 3 full business days thereafter as the Representative and the Company may determine. (b) Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as one enterprise which, in the judgment of a majority in interest of the Purchasers including CSFB, is material and adverse and makes it impractical or inadvisable to proceed with completion of the offering or the sale of and payment for the Offered Securities as contemplated by this agreement; (ii) any downgrading in the rating of any debt securities of the Company by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement that the Company has been placed on negative outlook; (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of a majority in interest of the Purchasers including CSFB, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities as contemplated by this agreement, whether in the primary market or in respect of dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange, or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of securities or clearance services in the United States; or (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of a majority in interest of the Purchasers including CSFB, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the offering or the sale of and payment for the Offered Securities. (c) The Representative shall have received an opinion, dated the Closing Date, of Hunton & Williams LLP, counsel for the Company, in substantially the form of Exhibit 2 hereto. (d) The Representative shall have received opinions, dated the Closing Date, from foreign counsel, concerning the Non-Swiss Foreign Guarantors and the Swiss Guarantors named in Schedule D hereto, in form and substance reasonably acceptable to the Representative and customary for the type of transactions contemplated by this Agreement. (e) The Representative shall have received from Latham & Watkins LLP, counsel for the Purchasers, such opinion or opinions, dated the Closing Date, with respect to the incorporation of the Company, the validity of the Offered Securities, the Final 15 Offering Circular, the exemption from registration for the offer and sale of the Offered Securities by the Company to the several Purchasers and the resales by the several Purchasers as contemplated hereby and other related matters as CSFB reasonably may require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. (f) The Representative shall have received a certificate, dated the Closing Date, of the President or any Vice President and a principal financial or accounting officer of the Company in which such officers, to the best of their knowledge after reasonable investigation, shall state, on behalf of the Company, each of the Domestic Guarantors and each of the Non-Swiss Foreign Guarantors, that the representations and warranties of the Company, each of the Domestic Guarantors and each of the Non-Swiss Foreign Guarantors, as applicable, in this Agreement are true and correct, that the Company and each of the Guarantors, as applicable, has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date, and that, subsequent to the most recent financial statements included or incorporated by reference in the Offering Document, there has been no Material Adverse Effect, nor any development or event that would reasonably be expected to result in a Material Adverse Effect, except as set forth in or contemplated by the Offering Document or Exchange Act Reports. (g) The Representative shall have received a letter, dated the Closing Date, of PricewaterhouseCoopers LLP which meets the requirements of subsection (a) of this Section, except that the specified date referred to in such subsection will be a date not more than three days prior to the Closing Date for the purposes of this subsection and such letter shall include all information contained in the Final Offering Circular that would otherwise have been included in the "comfort letter" required pursuant to subsection (a) had the Final Offering Circular been finalized on the date hereof. (h) The Company shall, concurrently with the issuance of the Offered Securities on the Closing Date, enter into a new senior credit facility (the "New Senior Credit Facility") and the New Senior Credit Facility shall be in full force and effect on the Closing Date, and the New Senior Credit Facility shall conform in all material respects to the description thereof contained in the Offering Document. The Company will furnish the Representative with such conformed copies of such opinions, certificates, letters and documents as the Representative may reasonably request. CSFB may in its sole discretion waive on behalf of the Purchasers compliance with any conditions to the obligations of the Purchasers hereunder. 7. Indemnification and Contribution. (a) The Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors will, jointly and severally, indemnify and hold harmless each Purchaser, its partners, directors and officers and each person, if any, who controls such Purchaser within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such Purchaser may become subject, 16 under the Securities Act or 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 any untrue statement or alleged untrue statement of any material fact contained in the Offering Document, or any amendment or supplement thereto, or any related preliminary offering circular, or arise out of or are based upon the 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, including any losses, claims, damages or liabilities arising out of or based upon the Company's failure to perform its obligations under Section 5(a) of this Agreement, and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such Purchaser in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that none of the Company or any of the Guarantors will be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Purchaser through CSFB specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below. (b) Each Purchaser will severally and not jointly indemnify and hold harmless the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors, their respective directors and officers and each person, if any, who controls the Company or such Domestic Guarantor or such Non-Swiss Foreign Guarantor within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Company or such Domestic Guarantor or such Non-Swiss Foreign Guarantor may become subject, under the Securities Act or 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 any untrue statement or alleged untrue statement of any material fact contained in the Offering Document, or any amendment or supplement thereto, or any related preliminary offering circular, or arise out of or are based upon the omission or the 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 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 furnished to the Company by such Purchaser through CSFB specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Purchaser consists of (i) the following information in the Preliminary Offering Circular: (A) the last two sentences on page 8, (B) the second sentence of the second paragraph on page 17, (C) the table set forth on page 97, (D) the first sentence of the sixth paragraph on page 97, and (E) the second sentence of the second paragraph on page 98, and (ii) the names of the Purchasers on the cover page of the Final Offering Circular and the corresponding information in the Final Offering Circular, provided, however, that the Purchasers shall not be liable for any 17 losses, claims, damages or liabilities arising out of or based upon the Company's failure to perform its obligations under Section 5(a) of this agreement. (c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this section 7 except to the extent that the indemnifying party 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 party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (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 (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 (i) an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to or an admission of fault-culpability or failure to act by or on behalf of any indemnified party. (d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors on the one hand and the Purchasers on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (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 (i) above but also the relative fault of the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting 18 expenses) received by the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors bear to the total discounts and commissions received by the Purchasers from the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors or the Purchasers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total discounts, fees and commissions received by such Purchaser exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers' obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. 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. (e) The obligations of the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors under this Section shall be in addition to any liability which the Company and the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Purchaser within the meaning of the Securities Act or the Exchange Act; and the obligations of the Purchasers under this Section shall be in addition to any liability which the respective Purchaser may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Company or any of the Guarantors within the meaning of the Securities Act or the Exchange Act. 8. Default of Purchasers. If any Purchaser or Purchasers default in their obligations to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, CSFB may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase. If any Purchaser or Purchasers so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to CSFB and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser, the Company or the Guarantors, except as provided in 19 Section 9. As used in this Agreement, the term "Purchaser" includes any person substituted for a Purchaser under this Section. Nothing herein will relieve a defaulting Purchaser from liability for its default. 9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors or their respective officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Purchasers is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5(h) and the respective obligations of the Company, the Domestic Guarantors and the Non-Swiss Foreign Guarantors and the Purchasers pursuant to Section 7 shall remain in effect, provided, however, if the Company does not enter into the New Senior Credit Facility as specified in Section 6(h), the Company shall not be responsible for the expenses to be paid or reimbursed by it pursuant to Section 5(h). If the purchase of the Offered Securities by the Purchasers is not consummated for any reason other than (x) solely because of the occurrence of any event specified in clause (iii), (iv), (v), (vi) or (vii) of Section 6(b), or (y) the Company does not enter into the New Senior Credit Facility as specified in Section 6(h), the Company will reimburse the Purchasers for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by it in connection with the offering of the Offered Securities. 10. Notices. All communications hereunder will be in writing and, if sent to the Purchasers will be mailed, delivered or faxed and confirmed to the Purchasers, c/o Credit Suisse First Boston LLC at Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: Investment Banking Department - Transactions Advisory Group (fax # 212-538-8246), or, if sent to the Company or the Guarantors, will be mailed, delivered or faxed and confirmed to it at Ethyl Corporation, 330 South Fourth Street, P.O. Box 2189, Richmond, Virginia 23218-2189, Attention: Secretary (fax # 804-788-5688). 11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder, except that holders of Offered Securities shall be entitled to enforce the agreements for their benefit contained in the second and third sentences of Section 5(b) hereof against the Company and the Guarantors as if such holders were parties thereto. 12. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement. 20 13. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws. 14. Submission to Jurisdiction. The Company and the Guarantors hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. 15. Amendments or Waivers. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the Company, the Guarantors and the Representative. 16. Swiss Guarantors. Each of the Swiss Guarantors is executing this Agreement solely to evidence its obligation to issue its respective Subsidiary Guarantee and Exchange Security Guarantee pursuant to the terms of the Indenture. Each of Ethyl Services GmbH's and Ehtyl Administration GmbH's liability (whether arising under contract, tort or otherwise) under this Agreement shall at all times be limited to the amount of its balance sheet profit available at the time of the payment, as determined by their respective independent auditors, based upon their duly audited financial statements at the time of such payment, taking into consideration any reduction of the balance sheet profit from the date of the annual financial statements and the time of the payment, minus 35% for the applicable withholding tax. 17. Entire Agreement. This Agreement, including the Schedules and Exhibit hereto, the Registration Rights Agreement, the Indenture, the Offered Securities, the Subsidiary Guarantees, the Exchange Securities and the Exchange Security Guarantees constitute the entire agreement among the parties pertaining to the subject matter hereof and supercedes all other prior and contemporaneous agreements and understandings, both oral and written, of the parties in connection therewith. 21 If the foregoing is in accordance with the Purchasers' understanding of our agreement, kindly sign and return to us one of the counterparts hereof, whereupon it will become a binding agreement among the Company, the Guarantors and the several Purchasers in accordance with its terms.
