The Partnership may have filed one or more amendments thereto, including a related Preliminary Prospectus, each of which has previously been furnished to you. The Partnership will file with the Commission a final prospectus in accordance with Rule 424(b). As filed, such final prospectus shall contain all information required by the Act and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to the Representatives prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the latest Preliminary Prospectus) as the Partnership has advised the Representatives, prior to the Execution Time, will be included or made therein.

(b) No stop order suspending the effectiveness of the Registration Statement, any post-effective amendment thereto or the Rule 462(b) Registration Statement, if any, has been issued under the Act, and no proceeding for that purpose or pursuant to Section 8A of the Act has been initiated or, to the knowledge of any of the PennTex Parties, threatened by the Commission.

On the Effective Date, the Registration Statement did, and when the Prospectus is first filed in accordance with Rule 424(b) and on the Closing Date and on any date on which Option Units are purchased, if such date is not the Closing Date (a “settlement date”), the Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act; on the Effective Date and at the Execution Time, the Registration Statement did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any settlement date, the Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the PennTex Parties make no representations or warranties as to the information contained in or omitted from the Registration Statement, each Preliminary Prospectus or the Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Partnership by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement, each Preliminary Prospectus or the Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof.

(e) Each of the statements made by the Partnership in the Registration Statement and the Disclosure Package and to be made in the Prospectus (and any supplements thereto) within the coverage of Rule 175(b) under the Act, including (but not limited to) any statements with respect to projected results of operations, estimated available cash and future cash distributions of the Partnership, and any statements made in support thereof or related thereto under the heading “Our Cash Distribution Policy and Restrictions on Distributions” or the anticipated ratio of taxable income to distributions, was made or will be made with a reasonable basis and in good faith.

(g) (i) At the time of filing the Registration Statement and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Partnership was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Partnership be considered an Ineligible Issuer.

(h) From the time of the initial confidential submission of the Registration Statement to the Commission (or, if earlier, the first date on which the Partnership engaged directly or through any person authorized to act on its behalf in any Testing-the-Waters Communication) through the Execution Time, the Partnership has been and is an “emerging growth company,” as defined in Section 2(a) of the Act (an “Emerging Growth Company”).

(i) The Partnership (i) has not alone engaged in any Testing-the-Waters Communication other than Testing-the-Waters Communications with the consent of the Representatives with entities that are qualified institutional buyers within the meaning of Rule 144A or institutions that are accredited investors within the meaning of Rule 501 and (ii) has not authorized anyone other than the Representatives to engage in

(ee) The historical consolidated financial statements and schedules of each of the Partnership and PennTex Operating included in the Registration Statement, the Preliminary Prospectus and the Prospectus present fairly in all material respects the financial condition, results of operations and cash flows of the Partnership and PennTex Operating, as applicable, as of the dates and for the periods indicated, comply as to form with the applicable accounting requirements of the Act, and have been prepared in conformity with generally accepted accounting principles in the United States applied on a consistent basis throughout the periods involved (except as otherwise noted therein). The pro forma financial statements of the Partnership included in the Registration Statement, the Preliminary Prospectus and the Prospectus include assumptions that provide a reasonable basis for presenting the significant effects directly attributable to the transactions and events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro forma adjustments reflect the proper application of those adjustments to the historical financial statement amounts in the pro forma financial statements included in the Registration Statement, the Preliminary Prospectus and the Prospectus. The pro forma financial statements of the Partnership included in the Registration Statement, the Preliminary Prospectus and the Prospectus comply as to form in all material respects with the applicable accounting requirements of the Act (including, without limitation, Regulations S-X and G of the Act), Item 10 under Regulation S-K and Financial Interpretation No. 46 and the pro forma adjustments have been properly applied to the historical amounts in the compilation of those statements. The summary historical and pro forma financial information set forth in the Registration

Statement, the Preliminary Prospectus and the Prospectus under the caption “Summary—Summary Historical and Pro Forma Financial Data” and the selected historical and pro forma financial information set forth under the caption “Selected Historical and Pro Forma Financial Data” in the Registration Statement, the Preliminary Prospectus and the Prospectus are accurately presented in all material respects and prepared on a basis consistent with the audited and unaudited historical financial statements and pro forma financial statements, as applicable, from which they have been derived.

(b) If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b), any event occurs as a result of which (i) the Disclosure Package or any Issuer Free Writing Prospectus 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 (ii) any Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the most recent Preliminary Prospectus or the Prospectus, the Partnership will (A) notify promptly the Representatives so that any use of the Disclosure Package or the Issuer Free Writing Prospectus, as the case may be, may cease until it is amended or supplemented; (B) amend or supplement the Disclosure Package or the Issuer Free Writing Prospectus, as the case may be, to correct such statement, omission or conflict; and (C) supply any amendment or supplement to the Representatives in such quantities as they may reasonably request.

(c) 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 Disclosure Package or 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 Disclosure Package or Prospectus to comply with the Act, the Partnership promptly will (i) notify the Representatives of any 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 which will correct such statement or omission or effect such compliance; and (iii) supply any supplemented Prospectus to the Representatives in such quantities as they may reasonably request.

The Partnership will pay the expenses of printing or other production of all documents relating to the offering.

(f) The Partnership will arrange, if necessary, for the qualification of the Units for sale under the laws of such jurisdictions as the Representatives may designate and will maintain such qualifications in effect so long as required for the distribution of the Units; 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.

(g) The Partnership will not, without the prior written consent of Citigroup Global Markets 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, 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 with respect to, any Common Units or any securities convertible into or exercisable or exchangeable for Common Units, or publicly announce an intention to effect any such transaction, for a period of 180 days (the “Lock-Up Period”) after the date of this Agreement; provided, however, that the Partnership may, without the prior written consent of Citigroup Global Markets Inc., (A) effect the registration of the offer and sale of the Units as contemplated by this Agreement; (B) issue and sell any Common Units, options to purchase Common Units or other equity incentive awards, in each case issued or granted pursuant to the LTIP, and file a registration statement on Form S-8 relating to, the LTIP; and (C) Common Units, Subordinated Units and other equity securities convertible or exchangeable into Common Units, issued by the Partnership up to an aggregate of 10% of the Common Units to be outstanding immediately following the sale of the Firm Units pursuant to this Agreement, in connection with the acquisition by the Partnership or any of its subsidiaries of the securities, business property or other assets of another person or entity or pursuant to any plan assumed by the Partnership in connection with such acquisition; provided, however, that securities issued by the Partnership pursuant to clause (C) shall be subject to the restrictions set forth in this Section 5(g).

(h) The PennTex Parties will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Units.

(i) The Partnership agrees to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Prospectus, the Prospectus and each Issuer Free Writing Prospectus, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Prospectus, each Issuer Free Writing Prospectus and each Written Testing-the-Waters Communication, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Units; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Units, including any stamp or transfer taxes in connection with the original issuance and sale of the Units; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Units; (v) the registration of the Units under the Exchange Act and the listing of the Units on NASDAQ; (vi) any registration or qualification of the Units for offer and sale under the securities or blue sky laws of the several states (including filing fees); (vii) any filings required to be made with FINRA, including filing fees and attorneys’ fees (such attorneys’ fees not to exceed $25,000 in the aggregate); (viii) the transportation and other expenses incurred by or on behalf of the Partnership in connection with presentations to prospective purchasers of the Units (except that 50% of the cost of any aircraft chartered in connection with the roadshow will be paid by the Underwriters); (ix) the fees and

expenses of the PennTex Parties’ accountants and the fees and expenses of counsel (including local and special counsel) for the Partnership; and (x) all other costs and expenses incident to the performance by the Partnership Parties of their obligations hereunder; provided that except as provided in this Section 5 and in Section 7 hereof, the Underwriters shall pay their own costs and expenses, including, without limitation, the costs and expenses of their counsel, any transfer taxes on the Units that they may sell and the expenses of advertising any offering of the Units made by the Underwriters.

(j) The Partnership agrees to pay (i) all fees and disbursements of counsel incurred by the Underwriters in connection with the Directed Unit Program in an amount not to exceed $25,000, (ii) all costs and expenses incurred by the Underwriters in connection with the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of copies of the Directed Unit Program materials and (iii) all stamp duties, similar taxes or duties or other taxes, if any, incurred by the Underwriters in connection with the Directed Unit Program. Furthermore, the Partnership Parties covenant with the Underwriters that the Partnership will comply with all applicable securities and other applicable laws, rules and regulations in each foreign jurisdiction in which the Directed Units are offered in connection with the Directed Unit Program.

(k) The Partnership agrees that, unless it has or shall have obtained the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Partnership that, unless it has or shall have obtained, 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; provided, that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectuses included in Schedule II hereto and any electronic road show. Any such free writing prospectus consented to by the Representatives or the Partnership is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (ii) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(l) The Partnership will use the net proceeds received by it from the sale of the Units in the manner specified in the Registration Statement, the Disclosure Package and the Prospectus under “Use of Proceeds.”

(m) The Partnership will use its reasonable best efforts to effect and maintain the listing of the Common Units on NASDAQ.

(o) If at any time following the distribution of any Written Testing-the-Waters Communication, any event occurs as a result of which such Written Testing-the-Waters Communication 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 at such time not misleading, the Partnership will (i) notify promptly the Representatives so that use of the Written Testing-the-Waters Communication may cease until it is amended or supplemented; (ii) amend or supplement the Written Testing-the-Waters Communication to correct such statement or omission; and (iii) supply any amendment or supplement to the Representatives in such quantities as may be reasonably requested.

6. Conditions to the Obligations of the Underwriters.

(b) The Partnership shall have requested and caused Xxxxxx & Xxxxxxx LLP, counsel for the PennTex Parties, to have furnished to the Representatives its legal opinion and letters, each dated the Closing Date and any settlement date pursuant to Section 3 hereof, and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representatives, substantially in the form set forth on Exhibit B-1, Exhibit B-2 and Exhibit B-3.

(e) The General Partner shall have furnished to the Representatives certificates of the Chairman, the President or the Chief Executive Officer of the General Partner (or persons holding similar positions, as applicable) and of the Chief Financial Officer or Chief Accounting Officer of the General Partner (or persons holding similar positions, as applicable), dated the Closing Date and any settlement date pursuant to Section 3 hereof, to the effect that the signers of each such certificate have carefully examined the Registration Statement, the Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus and any amendment or supplement thereto, as well as each electronic roadshow used in connection with the offering of the Units, and this Agreement and that:

(i) the representations and warranties of such PennTex Party in this Agreement are true and correct on and as of the Closing Date and any settlement date pursuant to Section 3 hereof, with the same effect as if made on the Closing Date and any settlement date pursuant to Section 3 hereof, and such PennTex Party has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied on or prior to such Closing Date or settlement date, as applicable;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the knowledge of such PennTex Party, threatened; and

References to the Prospectus in this paragraph (f) include any supplement thereto at the date of the respective 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 Prospectus (exclusive of any amendment or supplement thereto), there shall not have been any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties (including, for the avoidance of doubt, the Partnership Properties) of the Partnership Parties taken as a whole, whether or not arising from transactions in the ordinary course of business, except as described in the Disclosure Package and the Prospectus (exclusive of any supplement thereto) the effect of which is, in the sole judgment of the Representatives, 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 Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto).

(h) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Partnership Parties’ debt securities, if any, by any “nationally recognized statistical rating organization” (as defined for purposes of Section 3(a)(62) of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(i) The Units shall have been approved for listing and admitted and authorized for trading on NASDAQ, and satisfactory evidence of such actions shall have been provided to the Representatives.

(j) At the Execution Time, the Partnership shall have furnished to the Representatives a letter substantially in the form of Exhibit A hereto from each of the parties listed on Schedule III hereto and addressed to the Representatives.

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 Representatives and Xxxxxx & Xxxxxx L.L.P., 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 Representatives. 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 at the office of Xxxxxx & Xxxxxx L.L.P., counsel for the Underwriters, at 0000 Xxxxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, on the Closing Date and any settlement date pursuant to Section 3 hereof.

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, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the PennTex Parties to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the PennTex Parties will reimburse the Underwriters severally through Citigroup Global Markets Inc. on demand for all reasonable 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) The PennTex Parties jointly and severally agree to indemnify and hold harmless each Underwriter, the directors, officers, managers, employees and agents of each Underwriter, affiliates of each Underwriter who have, or are alleged to have, participated in the distribution of Units as underwriters, 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 any Preliminary Prospectus, the Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication 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, in the light of the circumstances under which they were made (with respect to any Preliminary Prospectus, the Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus), 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 indemnifying party shall not be obligated to pay the fees and expenses of more than one counsel chosen by the Underwriters (other than any local counsel and subject to the additional obligations set forth in Section 8(c)); provided, further that the PennTex 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 through the Representatives specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8(b) hereof. This indemnity agreement will be in addition to any liability which the PennTex Parties may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the PennTex Parties, each of the General Partner’s directors and officers who signs the Registration Statement, and each person who controls the PennTex Parties within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the PennTex Parties to each Underwriter, but only with reference to written information furnished to the Partnership by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The PennTex Parties acknowledge that (i) the list of Underwriters and their respective participation in the sale of the Units, (ii) the sentences related to concessions and reallowances and (iii) the paragraph related to stabilization, syndicate covering transactions, penalty bids and the information regarding the limitation on sales to discretionary accounts, in each case under the heading “Underwriting” in the Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Registration Statement, Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communications.

(c) Each of the PennTex Parties agrees, jointly and severally, to indemnify and hold harmless Xxxxx Fargo Securities, LLC, the directors, officers, managers, employees and agents of Xxxxx Fargo Securities, LLC and each person who controls Xxxxx Fargo Securities, LLC within the meaning of either the Act or the Exchange Act (“Xxxxx Fargo Entities”), from and against any and all losses, claims, damages and liabilities to which they may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim), insofar as such losses, claims damages or liabilities (or actions in respect thereof) (i) arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact regarding the PennTex Parties contained in any material prepared by or with the approval of the Partnership for distribution to Directed Unit Participants in connection with the Directed Unit Program or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) are caused by the failure of any Direct Unit Participant to pay for and accept delivery of the Directed Units which immediately following the Effective Date of the Registration Statement, were subject to a properly confirmed agreement to purchase; or (iii) relate to, arise out of, or were incurred in connection with the Directed Unit Program, except that this clause (iii) shall not apply to the extent that such loss, claim, damage or liability is finally judicially determined to have resulted primarily from the gross negligence or willful misconduct of Xxxxx Fargo Entities.

(d) 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), (b) or (c) 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), (b) or (c) 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 reasonably satisfactory to the indemnified party (which consent shall not be unreasonably withheld). 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 one separate counsel (in addition to 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 reasonably 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 (which consent shall not be unreasonably withheld), 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 and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to Section 8(c) indemnifying one or more Xxxxx Fargo Entities for damages arising out of the Directed Unit Program hereof in respect of such action or proceeding, then in addition to such separate counsel for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate counsel (in addition to any local counsel) for the Xxxxx Fargo Entities for the defense of any losses, claims, damages and liabilities arising out of the Directed Unit Program.

(e) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the PennTex Parties, jointly and severally, on the one hand, and the Underwriters severally, on the other hand, agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the PennTex Parties, on the one hand, and one or more of the Underwriters, on the other hand, may be subject in such proportion as is appropriate to reflect the relative benefits received by the PennTex Parties, jointly and severally, on the one hand, and by the Underwriters, on the other hand, 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 PennTex Parties, jointly and severally, on the one hand, and the Underwriters severally, on the other hand, shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the PennTex Parties, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the PennTex Parties shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses and applicable structuring and advisory fees) received by the each of them, 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 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 PennTex Parties or by the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The PennTex Parties on the one hand and the Underwriters on the other hand 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 (e), 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(e), (i) each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, manager, employee, affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and (ii) each person who controls the PennTex Parties within the meaning of either the Act or the Exchange Act, each officer of the General Partner who shall have signed the Registration Statement and each director of the General Partner shall have the same rights to contribution as the PennTex Parties, subject in each case to the applicable terms and conditions of this paragraph (e).

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 that 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 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 PennTex Parties other than as contemplated by Sections 5(i), 7 and 8. 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 Representatives shall determine in order that the required changes in the Registration Statement and the 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.
