Additionally, no relationship, direct or indirect, exists between any of the Martin Parties, Prism Gas or Waskom on the one hand, and the directors, officers, stockholders, customers or suppliers of any of the Martin Parties, Prism Gas or Waskom on the other hand, that is required by the Act to be disclosed in the Registration Statement and the Final Prospectus that is not so disclosed.

All property (real and personal) held under lease by the Partnership Entities or Waskom is held by them under valid, enforceable leases with only such exceptions as in the aggregate are not materially burdensome and do not have and will not result in a Material Adverse Effect.
     (qq) Each of the Partnership Entities and Waskom has all permits, licenses, franchises, approvals, consents and authorizations of governmental or regulatory authorities (hereinafter “permit” or “permits”) as are necessary to own or lease its properties and to conduct its business in the manner described in the Preliminary Final Prospectus and the Final Prospectus, subject to such qualifications as may be set forth in the Preliminary Final Prospectus and the Final Prospectus, except where the failure to have obtained any such permit has not had and will not have a Material Adverse Effect.
     (rr) The Partnership Entities and Waskom maintain a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorizations and (iv) the recorded amount of assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.
     (ss) The principal executive officer and the principal financial officer of the General Partner of the Partnership have made all certifications relating to the Partnership required by the Sarbanes-Oxley Act or any related rules and regulations promulgated by the Commission, and the statements contained in any such certification were complete and correct when made. The Partnership maintains “disclosure controls and procedures” (as defined in Rule 13a-15 under the Exchange Act), and such controls and procedures are designed (i) to ensure that information required to be disclosed by the Partnership in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms and (ii) to ensure that information required to be disclosed by the Partnership in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Partnership’s management, including the principal executive officer and principal financial officer of the General Partner of the Partnership, as appropriate to allow timely decisions regarding required disclosure. The Partnership does not

13


 

have any material weaknesses in internal controls, and there has been no fraud, whether or not material, that involves management or other employees who have a significant role in the Partnership’s internal controls. The Partnership is otherwise in compliance in all material respects with all applicable effective provisions of the Sarbanes-Oxley Act and the rules and regulations promulgated by the Commission.
     (tt) Except as described in the Preliminary Final Prospectus and the Final Prospectus, the Partnership Entities and Waskom (i) are in compliance with any and all applicable federal, state, local and foreign laws and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval, except where such noncompliance with Environmental Laws, failure to receive required permits, licenses or other approvals or failure to comply with the terms and conditions of such permits, licenses or other approvals would not, individually or in the aggregate, have a Material Adverse Effect. None of the Partnership Entities or Waskom has been named as a “potentially responsible party” under the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended, in regard to any unresolved matter or claim. None of the Partnership Entities or Waskom owns, leases or occupies any property requiring remediation that appears on any list of hazardous sites compiled by any state or local governmental agency. In the ordinary course of its business, each of the Partnership Entities and Waskom conducts a periodic review of the effect of Environmental Laws on its business, operations and properties, in the course of which it identifies and evaluates associated costs and liabilities (including any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review and amount of its established reserves, each of the Partnership Entities and Waskom has reasonably concluded that such associated costs and liabilities would not, individually or in the aggregate, result in a Material Adverse Effect.
     (uu) The Partnership has procured lock-up agreements, in the form of Exhibit A attached hereto (“Lock-Up Agreements”), from MRMC, Midstream, MPS and each of the executive officers and directors of the General Partner.

     (ww) Each of the Partnership Entities is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in which it is engaged; and none of the Partnership Entities has reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a comparable cost.
     (xx) Except for the Martin Midstream Partners L.P. Long-Term Incentive Plan (the “Plan”), none of the Partnership Entities or Waskom is a party to, or has any liability with

14


 

respect to, any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by them or their “ERISA Affiliates” (as defined below). “ERISA Affiliate” means, with respect to any Partnership Entity, any member of any group or organization described in Sections 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986 (as amended, the “Code”) of which such entity is a member. The Plan is in compliance with ERISA and all other applicable state and federal laws. No “reportable event” (as defined in ERISA) has occurred with respect to the Plan. The Plan, if it were to be terminated as of the Closing Date, would not have any “amount of unfunded benefit liabilities” (as defined in ERISA). None of the Partnership Entities, Waskom nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, the Plan or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each “employee benefit plan” established or maintained by any Partnership Entity or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, that would cause the loss of such qualification.
     (yy) Each of the statements made by the Partnership in the Registration Statement and the Final Prospectus within the coverage of Rule 175(b) under the Act, including (but not limited to) any statements with respect to future available cash or future cash distributions of the Partnership or the anticipated ratio of taxable income to cash distributions, was made with a reasonable basis and in good faith.

     (b) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership hereby grants an option to the Underwriter to purchase, severally and not jointly, up to the number of Option Units set forth in Schedule I hereto at the same purchase price per Unit as the Underwriter shall pay for the Underwritten Units. Said option may be exercised only to cover over-allotments in the sale of the Underwritten Units by the Underwriter. Said option may be exercised in whole or in part at any time on or before the 30th day after the date of the Final Prospectus upon written or telegraphic notice by the Underwriter to the Company setting forth the number of Option Units as to which the Underwriter is exercising the option and the settlement date.

Delivery of the Units shall be made to the Underwriter against payment by the Underwriter of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Partnership. Delivery of the Underwritten Units and the Option Units shall be made through the facilities of The Depository Trust Company unless the Underwriter shall otherwise instruct.

If settlement for the Option Units occurs after the Closing Date, the Partnership will deliver to the Underwriter on the settlement date for the Option Units (each, an “Option Closing Date”), and the obligation of the Underwriter to purchase the Option 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.

     (a) 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.

The Partnership will promptly advise the Underwriter 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, (i) when, prior to termination of the offering of the Units, any amendment to the Registration Statement shall have been filed or become effective, (ii) 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, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice that

16


 

would prevent its use or the institution or threatening of any proceeding for that purpose and (iv) 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 best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or prevention and, upon such issuance, occurrence or prevention, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or prevention, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.
     (b) To prepare a final term sheet, to the extent you require us to prepare a term sheet, containing solely a description of the Units, in a form approved by you and to file such term sheet pursuant to Rule 433(d) within the time required by such Rule.
     (c) If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Partnership will notify promptly the Underwriter so that any use of the Disclosure Package may cease until it is amended or supplemented.
     (d) If, at any time when a prospectus relating to the Units is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), 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, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Partnership promptly will (i) notify the Underwriter of such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.
     (e) As soon as practicable, the Partnership will make generally available to its security holders and to the Underwriter 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.
     (f) The Partnership will furnish to the Underwriter and counsel for the Underwriter, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Final Prospectus, the Final Prospectus and each Issuer Free

     (h) The Partnership agrees that, unless it obtains the prior written consent of the Underwriter, and the Underwriter agrees with the Partnership that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Partnership, it has not made and will not make any offer relating to the Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433, other than the final term sheet prepared and filed pursuant to Section 5 hereto; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto.

     (xvi) Each of the Operative Agreements to which any of the Martin Parties is a party has been duly authorized and validly executed and delivered by the Martin Parties that are parties thereto. Assuming due authorization, execution and delivery by each party other than a Martin Party, each of the Operative Agreements (other than any Operative Agreement governed by law other than Texas law) to which any of the Martin Parties is a party constitutes a valid and legally binding obligation of the Martin Parties that are parties thereto, enforceable against each such party in accordance with its terms, subject to (A) bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (B) public policy, applicable law relating to fiduciary duties and indemnification and contribution and an implied covenant of good faith and fair dealing.
     (xvii) Except as described in the Registration Statement and the Final Prospectus, to the knowledge of such counsel, there is no action, suit, inquiry, proceeding or investigation by or before any court or governmental or other regulatory or administrative agency or commission pending or threatened, against or involving any of the Martin Parties, or to which any of the Martin Parties or their properties are subject that are required to be described in the Registration Statement or the Final Prospectus that are not described as required therein.
     (xviii) None of the offering, issuance and sale of the Units by the Partnership, the execution, delivery or performance of this Agreement by the Martin Parties, or the consummation of the transactions contemplated hereby (A) conflicts with or will conflict with or constitutes or will constitute a breach or violation of, or a default under, the certificate or agreement of limited partnership, certificate of formation, limited liability company agreement, certificate or articles of incorporation or bylaws (or other organizational documents) of any of the Martin Parties or Prism Gas, (B) constitutes or will constitute a breach or violation of, or a default (or an event that, with notice or lapse of time or both, would constitute such a default) under, any Operative Agreement or any other agreement filed as an exhibit to the Registration Statement, (C) violates or will result in any violation of (assuming compliance with all applicable state securities and Blue Sky laws) any applicable Delaware, Texas or federal law or regulation, or any ruling, filing, judgment, injunction, order or decree of any Delaware, Texas or federal court or government agency applicable to the Martin Parties or Prism Gas, or (D) results

24


 

in or will result in the creation or imposition of any lien, encumbrance, security interest, charge or claim (other than Permitted Liens) upon any property or assets of any of the Partnership Entities, which conflicts, breaches, violations, defaults or liens, encumbrances, security interests, charges or claims, in the case of clauses (ii), (iii) or (iv), would individually or in the aggregate, result in a Material Adverse Effect.
     (xix) No consent, approval, authorization or other order of, or registration, qualification or filing with, any Delaware, Texas or federal court, regulatory body, administrative agency or other governmental body, agency or official is required on the part of any of the Partnership Entities for the valid offering, issuance and sale of the Units to the Underwriter under this Agreement, the execution, delivery and performance of this Agreement by the Martin Parties or the consummation by the Martin Parties of the transactions contemplated by this Agreement except (A) for such consents required under the Act and the Exchange Act or under state securities or “Blue Sky” laws, as to which such counsel need to express any opinion, (B) for such consents which have been obtained or made, (C) for such consents which (1) are of a routine or administrative nature and (2) are not customarily obtained or made prior to the consummation of transactions such as those contemplated by this Agreement or (D) for such consents which, if not obtained or made, would not, individually or in the aggregate, have a Material Adverse Effect.
     (xx) The Registration Statement has been declared effective by the Commission under the Act. To the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings for such purpose have been instituted or are pending or are contemplated or threatened by the Commission. Any required filing of the Final Prospectus and any supplement thereto pursuant to Rule 424(b) under the Act has been made in the manner and within the time period required by such Rule 424(b).
     (xxi) The Registration Statement, including any Rule 462 Registration Statement, the Final Prospectus and each amendment or supplement to the Registration Statement and the Final Prospectus, as of their respective effective or issue dates (other than the financial statements and the notes and schedules thereto, and the other financial, statistical and accounting data included in the Registration Statement, Prospectus and in the exhibits to or excluded from the Registration Statement, as to which no opinion need be given) comply as to form in all material respects with the requirements of the Act.
     (xxii) None of the Martin Parties or Prism Gas is, or will be after giving effect to the offering and sale of the Units and the application of the proceeds thereof as described in the Registration Statement and the Final Prospectus, an “investment company”, as such term is defined in the Investment Company Act of 1940, as amended.
     (xxiii) The opinion of Baker Botts L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed and the Underwriter may rely on such opinion as if it were addressed to them.

25


 

     (xxiv) The statements in the Registration Statement and Final Prospectus under the captions “Cash Distribution Policy,” “Description of the Common Units” and “The Partnership Agreement” accurately describe, in all material respects, the portions of the documents addressed thereby and, insofar as they purport to constitute summaries of law or legal conclusions, are accurate in all material respects; and the Common Units, the Subordinated Units and the Incentive Distribution Rights conform in all material respects to the descriptions thereof contained in the Registration Statement and Final Prospectus under the captions “Summary—The Offering,” “Cash Distribution Policy,” “Description of the Common Units” and “The Partnership Agreement.”
     (xxv) In rendering such opinion, counsel may rely, to the extent they deem such reliance proper, as to matters of fact upon certificates of officers of the Martin Parties and of government officials as well as on the legal opinion of local counsel as to certain legal matters, provided that counsel shall state their belief that they and you are justified in relying thereon. Copies of all such certificates shall be furnished to you and your counsel on the Closing Date and each Option Closing Date, as the case may be.
     (xxvi) In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Martin Parties and Prism Gas, the independent public accountants of the Partnership, and the Underwriter, at which the contents of the Registration Statement and the Final Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing on, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement and the Final Prospectus (except to the extent specified in the foregoing opinion), based on the foregoing, no information has come to such counsel’s attention that causes such counsel to believe that the Registration Statement (other than (i) the financial statements included or incorporated by reference therein, including the notes and schedules thereto and the auditors’ reports thereon, (ii) the other financial, statistical and accounting data included or incorporated by reference therein, and (iii) the exhibits thereto, as to which such counsel need not comment), as of its effective date contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Final Prospectus (other than (i) the financial statements included or incorporated by reference therein, including the notes and schedules thereto and the auditors’ reports thereon, (ii) the other financial, statistical and accounting data included or incorporated by reference therein, and (iii) the exhibits thereto, as to which such counsel need not comment), as of its issue date and the Closing Date contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.
     (c) The Underwriter shall have received from Vinson & Elkins L.L.P., counsel for the Underwriter, such opinion or opinions, dated the Closing Date and addressed to the Underwriter, with respect to the issuance and sale of the Units, the Registration Statement, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Underwriter may reasonably require, and the Martin Parties and their counsel shall have

26


 

furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.
     (d) The Partnership shall have furnished to the Underwriter a certificate of the General Partner, signed by the President and Chief Executive Officer and the Executive Vice President and Chief Financial Officer of the General Partner, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Final Prospectus, the Disclosure Package and any supplements or amendments thereto and this Agreement and that:
     (i) the representations and warranties of the Martin 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 Martin Parties have complied with all the agreements and satisfied all the conditions on their part to be performed or satisfied at or prior to the Closing Date;
     (ii) no stop order suspending the effectiveness of the Registration Statement or any notice that would prevent its use has been issued and no proceedings for that purpose have been instituted or, to any Martin Party’s knowledge, threatened; and
     (iii) since the date of the most recent financial statements included or incorporated by reference 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 Partnership and its subsidiaries, 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 Disclosure Package and the Final Prospectus (exclusive of any supplement thereto).
     (e) The Underwriter shall have received letters addressed to the Underwriter and dated the date hereof and the Closing Date or each Option Closing Date, as the case may be, from the firm of KPMG LLP, independent certified public accountants (i) confirming that they are independent public accountants within the meaning of the Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, and (ii) stating, as of the date thereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Registration Statement, the Disclosure Package and the Final Prospectus, as of a date not more than five days prior to the date thereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to representatives in connection with registered public offerings with respect to the financial statements and certain financial information contained in (or incorporated by reference in) the Registration Statement, the Disclosure Package and the Final Prospectus.
     (f) 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), the Final Prospectus (exclusive of any supplement thereto) or any Issuer Free Writing 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 (e) of this Section 6 or (ii) any change, or

27


 

any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Partnership and its subsidiaries, 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 Underwriter, 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), the Final Prospectus (exclusive of any supplement thereto) and any Issuer Free Writing Prospectus.
     (g) All corporate, partnership and limited liability company proceedings and other legal matters incident to the authorization, form and validity of this Agreement, the Operative Agreements, the Units, the Registration Statement and the Final Prospectus, and all other legal matters relating to this Agreement and the transactions contemplated hereby shall be reasonably satisfactory in all material respects to counsel for the Underwriter, and the Partnership shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters.
     (h) No stop order suspending the effectiveness of the Registration Statement shall have been issued by the Commission and no proceedings for that purpose shall be pending or, to the knowledge of the Partnership, shall be threatened or contemplated by the Commission at or prior to the Closing Date or each Option Closing Date, as the case may be; (i) no order suspending the effectiveness of the Registration Statement or the qualification or registration of the Units under the securities or Blue Sky laws of any jurisdiction shall be in effect and no proceeding for such purpose shall be pending or, to the knowledge of the Partnership, threatened or contemplated by the authorities of any jurisdiction; (ii) any request for additional information on the part of the staff of the Commission or any such authorities shall have been complied with to the satisfaction of the staff of the Commission or such authorities; (iii) after the date hereof, no amendment or supplement to the Registration Statement or the Final Prospectus shall have been filed unless a copy thereof was first submitted to you and you did not object thereto in good faith; and (iv) all of the representations and warranties of the Martin Parties contained in this Agreement shall be true and correct on and as of the date hereof and on and as of the Closing Date or Option Closing Date, as the case may be, as if made on and as of the Closing Date or Option Closing Date, as the case may be.
     (i) None of the Martin Parties shall have failed in any material respect at or prior to the Closing Date or each Option Closing Date, as the case may be, to have performed or complied with any of their agreements herein contained and required to be performed or complied with by them hereunder at or prior to the Closing Date or Option Closing Date, as the case may be.
     (j) The Partnership shall have furnished or caused to have been furnished to the Underwriter such further information, certificates and documents as the Underwriter may reasonably request.
     (k) The Partnership shall have received a letter from the Corporate Financing Department of the NASD confirming that such Department has determined to raise no objections

28


 

with respect to the fairness or reasonableness of the underwriting terms and arrangements of the offering contemplated hereby.
     (l) The NASDAQ Global Select Market shall have approved the Units for inclusion therein, subject only to official notice of issuance, and satisfactory evidence of such actions shall have been provided to the Underwriter.
     (m) At the Execution Time, the Martin Parties shall have furnished to the Underwriter a letter substantially in the form of Exhibit A hereto from each officer and director of the General Partner and from Midstream, MPS, Martin LLC and MRMC addressed to the Underwriter.
     (n) There shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the NASDAQ Global Select Market, or the establishing on such market by the SEC or by such market of minimum or maximum prices which are not in force and effect on the date hereof; (ii) a suspension or material limitation in trading in the Partnership’s securities on the NASDAQ Global Select Market or the establishing on such market by the SEC or by such market of minimum or maximum prices which are not in force and effect on the date hereof; (iii) a general moratorium on commercial banking activities declared by either federal or any applicable state authorities; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war, which in the judgment of the Underwriter makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Units in the manner contemplated in the Final Prospectus; or (v) any calamity or crisis, change in national, international or world affairs, act of God, change in the international or domestic markets, or change in the existing financial, political or economic conditions in the United States or elsewhere, the effect of which on the financial markets of the United States is such as to make it in the judgment of the Underwriter impracticable or inadvisable to proceed with the public offering or the delivery of the Units in the manner contemplated in the Final Prospectus.
     (o) If any of the conditions specified in this Section 6 shall not have been fulfilled 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 reasonably satisfactory in form and substance to the Underwriter and counsel for the Underwriter, this Agreement and all obligations of the Underwriter hereunder may be canceled at, or at any time prior to, the Closing Date by the Underwriter. Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing.
     (p) The documents required to be delivered by this Section 6 shall be delivered to Vinson & Elkins L.L.P., counsel for the Underwriter, at the office of Baker Botts L.L.P., counsel for the Martin Parties, at 2001 Ross Avenue, Suite 1100, Dallas, Texas, on the Closing Date.
     7. Reimbursement of Underwriter’s Expenses. If the sale of the Units provided for herein is not consummated because any condition to the obligations of the Underwriter set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Martin Parties to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriter, the Partnership will reimburse the Underwriter on demand for all out-of-pocket

29


 

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) The Martin Parties will indemnify and hold harmless the Underwriter from and against any losses, damages or liabilities to which the Underwriter may become subject, under the Act, or otherwise, insofar as such losses, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Final Prospectus, the Registration Statement, the Basic Prospectus, the Final Prospectus or any amendment or supplement thereto or (B) any Issuer Free Writing Prospectus used or referred to in any “free writing prospectus” (as defined in Rule 405) used or referred to by the Underwriter or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and will reimburse the Underwriter for any legal or other out-of-pocket expenses reasonably incurred by the Underwriter in connection with investigating, preparing, pursuing or defending against any such loss, damage, liability or action or claim, including, without limitation, any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to the indemnified party, as such expenses are incurred (including such losses, damages, liabilities or expenses to the extent of the aggregate amount paid in settlement of any such action or claim, provided that (subject to Section 8(c) hereof) any such settlement is effected with the written consent of the General Partner); provided, however, that the Martin Parties shall not be liable in any such case to the extent, but only to the extent, that any such loss, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Final Prospectus, the Registration Statement, the Basic Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto, in reliance upon and in conformity with written information relating to the Underwriter furnished to the Martin Parties by the Underwriter, expressly for use in the preparation thereof.
     (b) The Underwriter will indemnify and hold harmless the Martin Parties, from and against any losses, damages or liabilities to which the Martin Parties may become subject, under the Act or otherwise, insofar as such losses, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Final Prospectus, the Final Prospectus and the Disclosure Package or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in 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 the Registration Statement, any Preliminary Final Prospectus, the Final Prospectus and the Disclosure Package or any such amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of the Underwriter, expressly for use in the preparation thereof, and will reimburse the Martin Parties for any legal or other expenses incurred by the Martin Parties in connection with investigating or defending any such action or claim as such expenses are incurred (including such losses, damages, liabilities or expenses to

30


 

the extent of the aggregate amount paid in settlement of any such action or claim, provided that (subject to Section 8(c) hereof) any such settlement is effected with the written consent of the Underwriter).
     (c) Promptly after receipt by an indemnified party under Section 8(a) or 8(b) hereof of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under Section 8(a) or 8(b) hereof, notify each such indemnifying party in writing of the commencement thereof, but the failure so to notify such indemnifying party shall not relieve such indemnifying party from any liability except to the extent that it has been prejudiced in any material respect by such failure or from any liability that it may have to any such indemnified party otherwise than under Section 8(a) or 8(b) hereof. In case any such action shall be brought against any such indemnified party and it shall notify each indemnifying party of the commencement thereof, each such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party under Section 8(a) or 8(b) hereof similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of such indemnified party, be counsel to such indemnifying party), and, after notice from such indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under Section 8(a) or 8(b) hereof for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. The indemnified party shall have the right to employ its own counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party at the expense of the indemnifying party has been authorized by the indemnifying party, (ii) the indemnified party shall have been advised by such counsel that there may be a conflict of interest between the indemnifying party and the indemnified party in the conduct of the defense, or certain aspects of the defense, of such action (in which case the indemnifying party shall not have the right to direct the defense of such action with respect to those matters or aspects of the defense on which a conflict exists or may exist on behalf of the indemnified party) or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to such indemnified party to assume the defense of such action, in any of which events such fees and expenses to the extent applicable shall be borne, and shall be paid as incurred, by the indemnifying party. If at any time such indemnified party shall have requested such indemnifying party under Section 8(a) or 8(b) hereof to reimburse such indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 8(a) or 8(b) hereof effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of such request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request for reimbursement prior to the date of such settlement. No such indemnifying party shall, without the written consent of such indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not such indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of such indemnified party from

31


 

all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any such indemnified party. In no event shall such indemnifying parties be liable for the fees and expenses of more than one counsel, other than one local counsel, for all such indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.
     (d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to indemnify or hold harmless an indemnified party under Section 8(a) or 8(b) hereof in respect of any losses, damages or liabilities (or actions or claims in respect thereof) referred to therein, then each indemnifying party under Section 8(a) or 8(b) hereof shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages or liabilities (or actions or claims in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Martin Parties on the one hand, and the Underwriter on the other hand, from the offering of the Units. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 8(c) hereof and such indemnifying party was prejudiced in a material respect by such failure, then each such indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault, as applicable, of the Martin Parties on the one hand, and the Underwriter, on the other hand in connection with the statements or omissions that resulted in such losses, damages or liabilities (or actions or claims in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by, as applicable, the Martin Parties on the one hand and the Underwriter, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Martin Parties bear to the total underwriting discounts and commissions received by the Underwriter. The relative fault, as applicable, of the Martin Parties, on the one hand and the Underwriter, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Martin Parties on the one hand, or the Underwriter, on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Martin Parties and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by such an indemnified party as a result of the losses, damages or liabilities (or actions or claims in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the Underwriter 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 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 the Underwriter within the meaning of either the Act or the Exchange Act

     (e) The rights and obligations of the Martin Parties under this Section 8 shall be in addition to any liability that the Martin Parties may otherwise have and shall extend, upon the same terms and conditions, to each officer, director, employee, agent or other representative and to each person, if any, who controls the Underwriter within the meaning of the Act; and the obligations of the Underwriter under this Section 8 shall be in addition to any liability that the respective Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Partnership and General Partner who signed the Registration Statement and to each person, if any, who controls the Martin Parties within the meaning of the Act.
     9. Substitution of Underwriter. If the Underwriter is in default, then this Agreement (or, with respect to the Option Closing Date, the obligations of the Underwriter to purchase and of the Partnership to sell the Option Units) shall thereupon terminate, without liability on the part of the Martin Parties except for the expenses to be borne by the Partnership and the Underwriter as provided in Section 12 hereof and the indemnity and contribution agreements in Section 8 hereof, but nothing herein shall relieve a defaulting Underwriter from liability for its default.
     10. Termination.
