If settlement for the Additional Units occurs after the Closing Date, the Partnership will deliver to the Underwriters on the settlement date for the Additional Units, and the obligation of the Underwriters to purchase the Additional Units shall be conditioned upon receipt of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 6 hereof. 12 4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Units for sale to the public as set forth in the Final Prospectus. 5. Agreements. Each of the Alliance Parties, jointly and severally, agrees with the Underwriters that: (a) The Partnership will use its reasonable commercial efforts to cause the Registration Statement, if not effective at the Execution Time, and any amendment thereof, to become effective. Prior to the termination of the offering of the Units, the Partnership will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Final Prospectus) to the Basic Prospectus or any Rule 462(b) Registration Statement unless the Partnership has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. Subject to the foregoing sentence, if the Registration Statement has become or becomes effective pursuant to Rule 430A, or filing of the Final Prospectus is otherwise required under Rule 424(b), the Partnership will cause the Final Prospectus, properly completed, and any supplement thereto to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Underwriters of such timely filing. The Partnership will promptly advise the Underwriters (1) when the Registration Statement, if not effective at the Execution Time, shall have become effective, (2) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (3) when, prior to termination of the offering of the Units, any amendment to the Registration Statement shall have been filed or become effective, (4) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (5) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (6) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its reasonable commercial efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof. (b) If, at any time when a prospectus relating to the Units is required to be delivered under the Act, any event occurs as a result of which the Final Prospectus as then supplemented would include 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, or if it shall be necessary to amend the Registration Statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, the Partnership promptly will (1) notify the Underwriters of such event, (2) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such statement or omission or effect such compliance and (3) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request. 13 (c) As soon as practicable, the Partnership will make generally available to its security holders and to the Underwriters an earnings statement or statements of the Partnership and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act.

The Partnership will pay the expenses of printing or other production of all documents relating to the offering. (e) The Partnership will arrange, if necessary, for the qualification of the Units for sale under the laws of such jurisdictions as the Underwriters may reasonably designate, will maintain such qualifications in effect so long as required for the distribution of the Units and will pay any fee of the National Association of Securities Dealers, Inc., in connection with its review of the offering; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Units, in any jurisdiction where it is not now so subject. (f) The Partnership will not, without the prior written consent of Salomon Smith Barney Inc., offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership or any affiliate of the Partnership or any person in privity with the Partnership or any affiliate of the Partnership) directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units; or publicly announce an intention to effect any such transaction, until the Business Day set forth on Schedule II hereto, provided, however, that the Partnership may issue and sell Common Units pursuant to (i) the Alliance Resource Management GP, LLC 1999 Long-Term Incentive Plan, (ii) the Alliance Resource Management GP, LLC Supplemental Executive Retirement Plan and (iii) the Director's Deferred Compensation Program, each in effect at the Execution Time, and pursuant to (x) the Managing General Partner's capital contribution in connection with this Offering and (y) the conversion of securities or the exercise of warrants outstanding at the Execution Time.

(i) Each of the Alliance Entities will take such steps as shall be necessary to ensure that none of them shall become an "investment company" within the meaning of such term under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder. 6.

(e) The Partnership shall have furnished to the Underwriters a certificate signed by the President and Chief Executive Officer and the principal financial or accounting 23 officer of the Managing General Partner, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Final Prospectus, any supplements to the Final Prospectus and this Agreement and that: (i) the representations and warranties of the Alliance Parties in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Alliance Parties have complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date; (ii) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the Managing General Partner's knowledge, threatened; and (iii) since the date of the most recent financial statements included in the Final Prospectus (exclusive of any supplement thereto), there has been no material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Alliance Entities, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Final Prospectus (exclusive of any supplement thereto). (f) The Partnership shall have requested and caused Deloitte & Touche LLP to have furnished to the Underwriters, at the Execution Time and at the Closing Date, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance reasonably satisfactory to the Underwriters, confirming that they are independent auditors within the meaning of the Act and the Exchange Act and the respective applicable rules and regulations adopted by the Commission thereunder and that they have performed a review of the unaudited interim financial information of the Partnership for the three-month periods ended March 31, 2002 and 2001, the three-month and six-month period ended June 30, 2002 and 2001, the three-month and nine-month periods ended September 30, 2002 and 2001, and the three-month periods ended December 31, 2002 and 2001 and the year ended December 31, 2002, in accordance with Statement on Auditing Standards No. 71, and stating in effect, that: (i) in their opinion the audited financial statements and financial statement schedules included in the Registration Statement and the Final Prospectus and reported on by them comply as to form in all material respects with the applicable accounting requirements of the Act and the Exchange Act and the related rules and regulations adopted by the Commission; (ii) on the basis of a reading of the latest unaudited financial statements made available by the Alliance Entities; their limited review, in accordance with standards established under Statement on Auditing Standards No. 71, of the unaudited consolidated interim financial information for the three-month periods ended March 31, 2002 and 2001, the three-month and six-month period ended June 30, 2002 and 2001, the three-month and nine-month periods ended September 30, 2002 and 2001 in the Registration Statement and Final Prospectus and the three-month periods ended December 31, 2002 and 2001 and the year ended December 31, 2002 in the 8-K filed by 24 the Partnership January 29, 2003; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the 2002 minutes of the meetings of the General Partners; and inquiries of certain officials of the Alliance Entities who have responsibility for financial and accounting matters of the Alliance Entities as to transactions and events subsequent to December 31, 2001, nothing came to their attention which caused them to believe that: (A) the unaudited interim financial statements included in the Registration Statement and the Final Prospectus do not comply as to form in all material respects with applicable accounting requirements of the Act and with the related rules and regulations adopted by the Commission with respect to financial statements included or incorporated by reference in quarterly reports on Form 10-Q under the Exchange Act; and said unaudited financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included in the Registration Statement and the Final Prospectus; (B) with respect to the period subsequent to December 31, 2002, there were any changes, at a specified date not more than five days prior to the date of the letter, in the capital stock, increase in long-term debt of the Partnership, or decreases in the consolidated net current assets or the owners' equity/partners' capital of the Partnership as compared with the amounts shown on the December 31, 2002, unaudited consolidated balance sheet filed by the Partnership on Form 8-K on January 29, 2003, or for the period from January 1, 2003 to such specified date there were any decreases, as compared with the comparable period from January 1, 2003, in revenues or income of the Partnership, except in all instances for changes or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Partnership as to the significance thereof unless said explanation is not deemed necessary by the Underwriters; (iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Partnership) set forth in the Registration Statement and the Final Prospectus agrees with the analyses prepared by management from the accounting records of the Alliance Entities, excluding any questions of legal interpretation; and (iv) on the basis of a reading of the unaudited pro forma financial statements included or incorporated by reference in the Registration Statement and the Final Prospectus (the "pro forma financial statements"), carrying out certain specified procedures, inquiries of certain officials of the Partnership who have responsibility for financial and accounting matters, and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the unaudited pro forma financial statements, nothing came to their attention which caused them to believe that the unaudited pro forma financial statements do not comply as to form in all material 25 respects with the applicable requirements of Rule 11-02 of Regulation S-X and that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such statements. References to the Final Prospectus in this section (f) include any supplement thereto at the date of the letter. (g) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (f) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Alliance Entities, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Final Prospectus (exclusive of any supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Underwriters, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any supplement thereto). (h) Prior to the Closing Date, the Partnership shall have furnished to the Underwriters such further information, certificates and documents as the Underwriters may reasonably request. (i) The Units shall have been listed and admitted and authorized for quotation on the Nasdaq National Market System, and satisfactory evidence of such actions shall have been provided to the Underwriters. (j) At the Execution Time, the Partnership shall have furnished to the Underwriters a letter substantially in the form of Exhibit B hereto from each executive officer and director of the Managing General Partner addressed to the Underwriters. If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Underwriters and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Underwriters. Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing. The documents required to be delivered by this Section 6 shall be delivered on the Closing Date. 7. Reimbursement of Underwriters' Expenses. If the sale of the Units provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of the Partnership to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Partnership will reimburse the Underwriters 26 severally through Salomon Smith Barney Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Units. 8. Indemnification and Contribution. (a) Each of the Alliance Parties, jointly and severally, agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law 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 a material fact contained in the Registration Statement for the registration of the Units as originally filed or in any amendment thereof, or in the Basic Prospectus, or the Final Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Alliance Parties 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 such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of any Underwriter specifically for inclusion therein; provided further, that with respect to any untrue statement or omission or alleged untrue statement or omission in or from any Final Prospectus, the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of any Underwriter (or director, officer, employee, agent or controlling person thereof) from whom the person asserting any such loss, claim, damage or liability purchased the securities concerned, to the extent that any such loss, claim, damage or liability of such Underwriter (or director, officer, employee, agent or controlling person thereof) occurs under the circumstance where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (w) the Alliance Parties have previously furnished copies of the Final Prospectus to Salomon Smith Barney Inc., (x) delivery of the Final Prospectus was required by the Act to be made to such person, (y) the untrue statement or omission or alleged untrue statement or omission in or from the Basic Prospectus was corrected in the Final Prospectus and (z) there was not sent or given to such person, at or prior to the written confirmation of the sale of such securities to such person, a copy of the Final Prospectus. This indemnity agreement will be in addition to any liability which any Alliance Party may otherwise have. (b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Alliance Parties, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Partnership within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from Alliance Parties to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Partnership by or on behalf of such Underwriter- specifically for inclusion in the 27 documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Alliance Parties acknowledge that the statements set forth in the last paragraph of the cover page regarding delivery of the Units and, under the heading "Underwriting" or "Plan of Distribution," (i) the list of Underwriters and their respective participation in the sale of the Units, (ii) the sentences related to concessions and reallowances, (iii) the paragraph related to release of the lockup agreements and (iv) the paragraphs related to stabilization, syndicate covering transactions, penalty bids, passive market making transactions and compliance with Rule 2810 of the NASD's Conduct Rules in the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Final Prospectus. (c) Promptly after receipt by an indemnified party under this Section 8 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 this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and 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 paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel 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 actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, 28 the Alliance Parties and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Alliance Parties and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and by the Underwriters on the other from the offering of the Units; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Units) be responsible for any amount in excess of the underwriting discount or commission applicable to the Units purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Alliance Parties and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Alliance Parties on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Alliance Parties shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Alliance Parties on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Alliance Parties and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), 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 Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Alliance Parties within the meaning of either the Act or the Exchange Act, any of the directors or officers of the Alliance Parties who shall have signed the Registration Statement shall have the same rights to contribution as the Alliance Parties, subject in each case to the applicable terms and conditions of this paragraph (d). 9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Units agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Units set forth opposite their names in Schedule I hereto bears to the aggregate amount of Units set forth opposite the names of all the remaining Underwriters) the Units which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Units which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Units set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation 29 to purchase any, of the Units, and if such nondefaulting Underwriters do not purchase all the Units, this Agreement will terminate without liability to any nondefaulting Underwriter or the Partnership. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Underwriters shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Partnership and any nondefaulting Underwriter for damages occasioned by its default hereunder. 10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Underwriters, by notice given to the Partnership prior to delivery of and payment for the Units, if at any time prior to such time (i) trading in the Partnership's Common Units shall have been suspended by the Commission or the Nasdaq National Market or trading in securities generally on the New York Stock Exchange or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established on either of such Exchanges or the Nasdaq National Market, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Underwriters, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Final Prospectus (exclusive of any supplement thereto). 11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Alliance Parties or any of their respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Alliance Entities or any of their respective officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Units. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Underwriters, will be mailed, delivered or telefaxed to the Salomon Smith Barney Inc. General Counsel (fax no.: (212) 816-7912) and confirmed to the General Counsel, Salomon Smith Barney Inc., at 388 Greenwich Street, New York, New York, 10013, Attention: General Counsel; or, if sent to the Partnership, will be mailed, delivered or telefaxed to Thomas L.

This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder. 30 14. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 15. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement. 16. Headings.
