The statements made in the Pricing Disclosure Package and the Offering Memorandum, insofar as they purport to constitute summaries of the terms of the contracts and other documents described and filed, constitute accurate summaries of the terms of such contracts and documents in all material respects. Each such contract and other document is in full force and effect and (assuming that such contracts and

Except as described in the Pricing Disclosure Package and the Offering Memorandum, none of the Issuers or Guarantors is a party to any contract, agreement or understanding with any person (other than this Agreement) that would give rise to a valid claim against any of them or the Initial Purchasers for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Notes.

(zz) Stabilization. The Partnership Entities have not taken, directly or indirectly, any action that has constituted, or that was designed to or could reasonably be expected to cause or result in, the stabilization or manipulation of the price of any security of the Partnership in connection with the offering of the Notes.

In computing the amount of such contingent liabilities at any time, it is intended that such liabilities will be computed at the amount that, in the light of all the facts and circumstances existing at such time, represents the amount that can reasonably be expected to become an actual or matured liability.

(fff) Registration Rights Disclosed.

(d) If, at any time prior to completion of the distribution of the Notes by the Initial Purchasers to Eligible Purchasers, any event occurs or information becomes known that, in the judgment of any of the Issuers or Guarantors or in the opinion of counsel for the Initial Purchasers, should be set forth in the Pricing Disclosure Package or the Offering Memorandum so that the Pricing Disclosure Package or the Offering Memorandum, as then amended or supplemented, does not include an untrue statement of 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, or if it is necessary to supplement or amend the Pricing Disclosure Package or the Offering Memorandum in order to comply with any law, the Issuers and the Guarantors will forthwith prepare an appropriate supplement or amendment thereto, and will expeditiously furnish to the Initial Purchasers a reasonable number of copies thereof.

(l) The Issuers and the Guarantors will not, and will not permit any of their respective affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Notes that have been acquired by any of them, except for Notes purchased by any of the Partnership Entities and resold in a transaction registered under the Securities Act.

(m) The Issuers and the Guarantors agree not to sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Securities Act) that would be integrated with the sale of the Notes in a manner that would require the registration under the Securities Act of the sale to the Initial Purchasers or the Eligible Purchasers of the Notes.

(ii) That they have examined the Pricing Disclosure Package and the Offering Memorandum, and, in their opinion, (A) the Pricing Disclosure Package, as of the Applicable Time, and the Offering Memorandum, as of its date and as of the Closing Date, did not and do not contain an untrue statement of a material fact and did not and do not omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading and (B) since the date of the Pricing Disclosure Package and the Offering Memorandum, no event has occurred which should have been set forth in a supplement or amendment to the Pricing Disclosure Package and the Offering Memorandum; and

(n) The Notes shall be eligible for clearance and settlement through DTC.

8. Indemnification and Contribution.

(a) Each of the Issuers and Guarantors hereby agrees, jointly and severally, to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Notes), to which that Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) an untrue statement or alleged untrue statement of a material fact contained in (A) any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared or executed by any of the Issuers or Guarantors (or based upon any written information furnished by any of the Issuers or Guarantors) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), or (C) in any materials or information provided to investors by, or with the approval of, any of the Issuers or Guarantors in connection with the marketing of the offering of the Notes, including any “road show” or investor presentations made to investors by the Issuers (whether in person or electronically) (“Marketing Materials”), or (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Initial Purchaser, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Issuers and the Guarantors shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Disclosure Package or Offering Memorandum, or in any such amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Issuers by or on behalf of any Initial Purchaser specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Issuers and the Guarantors may otherwise have to any Initial Purchaser or to any affiliate, director, officer, employee or controlling person of that Initial Purchaser.

(b) Each Initial Purchaser, severally and not jointly, hereby agrees to indemnify and hold harmless each of the Issuers and Guarantors, their respective officers and employees, each of their respective directors, and each person, if any, who controls any of the Issuers or Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which any of the Issuers, Guarantors or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) an untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky Application, or (C) in any Marketing Materials, or (ii) the omission or alleged omission to state in any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials any material fact required to be stated herein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Issuers by or on behalf of that Initial Purchaser specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that any Initial Purchaser may otherwise have to any of the Issuers, Guarantors or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, 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 claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under paragraphs (a) or (b) above except to the extent it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under paragraphs (a) or (b) above. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought

under this Section 8, if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its respective directors, officers, employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) 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, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(a) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, from the offering of the Notes, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from

the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Issuers and the Guarantors, as set forth in the table on the cover page of the Offering Memorandum, on the one hand, and the total discounts and commissions received by the Initial Purchasers with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement as set forth on the cover page of the Offering Memorandum. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Issuers, the Guarantors or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Issuers shall be deemed to be also for the benefit of the Guarantors, and information supplied by the Issuers shall also be deemed to have been supplied by the Guarantors. The Issuers, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably 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 Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Notes distributed by it for any damages that such Initial Purchaser has paid or will become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective purchase obligations and not joint.

(e) The Initial Purchasers severally confirm and the Issuers and the Guarantors acknowledge and agree that the statements with respect to the offering of the Notes by the Initial Purchasers set forth in the section entitled “Plan of Distribution—Stabilization and Short Positions” in the Pricing Disclosure Package and the Offering Memorandum are correct and constitute the only information concerning such Initial Purchasers furnished in writing to any of the Issuers or Guarantors by or on behalf of the Initial Purchasers specifically for inclusion in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum or in any amendment or supplement thereto or in any Blue Sky Application or in any Marketing Materials.

9. Defaulting Initial Purchasers.

(a) If, on the Closing Date, any Initial Purchaser defaults in its obligations to purchase the Notes that it has agreed to purchase under this Agreement, the remaining non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Notes by the non-defaulting Initial Purchasers or other persons satisfactory to the Issuers on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-

defaulting Initial Purchasers do not arrange for the purchase of such Notes, then the Issuers shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Notes on such terms. In the event that within the respective prescribed periods, the non-defaulting Initial Purchasers notify the Issuers that they have so arranged for the purchase of such Notes, or the Issuers notify the non-defaulting Initial Purchasers that they have so arranged for the purchase of such Notes, either the non-defaulting Initial Purchasers or the Issuers may postpone the Closing Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Issuers or counsel for the Initial Purchasers may be necessary in the Pricing Disclosure Package, the Offering Memorandum or in any other document or arrangement, and the Issuers agree to promptly prepare any amendment or supplement to the Pricing Disclosure Package or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 9, purchases Notes that a defaulting Initial Purchaser agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuers as provided in paragraph (a) above, the aggregate principal amount of such Notes that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Notes, then the Issuers shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Notes that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Notes that such Initial Purchaser agreed to purchase hereunder) of the Notes of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made; provided that the non-defaulting Initial Purchasers shall not be obligated to purchase more than 110% of the aggregate principal amount of Notes that they agreed to purchase on the Closing Date pursuant to the terms of Section 3.

(c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Issuers as provided in paragraph (a) above, the aggregate principal amount of such Notes that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Notes, or if the Issuers shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Issuers or the Guarantors, except that each of the Issuers and Guarantors will continue to be liable for the payment of expenses as set forth in Sections 6 and 11 and except that the provisions of Section 8 shall not terminate and shall remain in effect.

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

10. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Initial Purchasers by notice given to and received by the Issuers prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(k), (m) or (o) shall have occurred or if the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement.

11. Reimbursement of Initial Purchasers’ Expenses. If (i) the Issuers for any reason fail to tender the Notes for delivery to the Initial Purchasers, or (ii) the Initial Purchasers decline to purchase the Notes for any reason permitted under this Agreement (other than Sections 7(o)(i)(A), (o)(ii), (o)(iii) or (o)(iv)), the Issuers and the Guarantors shall reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Initial Purchasers) incurred by the Initial Purchasers in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Issuers and the Guarantors shall pay the full amount thereof to the Representative. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Initial Purchasers or pursuant to Section 10 as a result of the occurrence of any of the events listed in Sections 7(o)(i)(A), (o)(ii), (o)(iii) or (o)(iv), the Issuers and the Guarantors shall not be obligated to reimburse any defaulting Initial Purchaser on account of those expenses.

12. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to any of the Initial Purchasers, shall be delivered or sent by hand delivery, mail, overnight courier or facsimile transmission to Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, New York 10010-3629, Attention: IBCM-Legal, facsimile number: (212) 325-4296, with a copy to Vinson & Elkins L.L.P., 1001 Fannin Street, Suite 2500, Houston, Texas 77002, Attention: Sarah K.

The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Pricing Disclosure Package or the Offering Memorandum, and we have not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Pricing Disclosure Package and the Offering Memorandum involve matters of a non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Pricing Disclosure Package and the Offering Memorandum (except to the extent stated in paragraphs 18, 19 and 20 above). Subject to the foregoing and on the basis of the information we gained in the course of performing the services referred to above, we advise you that nothing came to our attention that caused us to believe that:

(a) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted 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; or

(b) the Offering Memorandum, as of its date or as of the Closing Date, included or includes an untrue statement of a material fact or omitted or omits 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;

it being understood that in each case we have not been asked to, and do not express any belief with respect to (i) the financial statements and schedules or other financial, accounting or reserve information contained or included or incorporated by reference therein or omitted therefrom or (ii) representations and warranties and other statements of fact contained in the exhibits to the documents incorporated by reference therein.

The opinions set forth above are limited in all respects to matters governed by federal law, the laws of the State of New York, the Texas Limited Liability Company Act, the Delaware LP Act, the Delaware General Corporation Law and the Delaware LLC Act, in each case published and in effect on the date hereof, and we express no opinion as to any other laws.

The Trustee may rely on our opinions in paragraphs 1, 8, 10, 11, 12 and 13 above as if this letter had been addressed to it. Otherwise, we are furnishing this letter to the Initial Purchasers solely for their use in connection with the transactions consummated on the date hereof pursuant to the Purchase Agreement, and this letter may not be relied upon by any other person or for any other purpose. This letter speaks as of the date hereof, and we disclaim any obligation to update this letter.

Christopher R. Jones shall have furnished to the Initial Purchasers his written opinion, as general counsel to the Partnership Entities, addressed to the Initial Purchasers and dated the Closing Date, in form and substance reasonably satisfactory to Credit Suisse Securities (USA) LLC, to the effect that:

1. Legal Proceedings. To the knowledge of such counsel, there are no legal, governmental or regulatory investigations, actions, suits or proceedings pending or threatened to which any of the Partnership Entities is a party or to which any of their respective properties is subject that are required to be described in, or incorporated by reference into, the Pricing Disclosure Package or the Offering Memorandum but are not so described, or incorporated by reference into, in each case as required by the Securities Act;

2. Contracts to be Described or Filed. To the knowledge of such counsel, there are no agreements, contracts, indentures, leases or other instruments to which any of the Partnership Entities is a party that would be required to be described in a registration statement filed under the Securities Act or filed as exhibits to a registration statement of the Partnership pursuant to Item 601 of Regulation S-K that have not been described in, or incorporated by reference into, the Pricing Disclosure Package and the Offering Memorandum; and

3. No Conflicts. None of the issuance and sale of the Notes and the Guarantees, the execution, delivery and performance by the Issuers and the Guarantors of the Indenture and this Agreement and the consummation of the transactions contemplated hereby and thereby, violates or will violate any order, judgment, decree, or injunction known to such counsel to which any of the Partnership Entities is a party or any of their property or assets is subject, to the knowledge of such counsel, 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 agreement or other instrument to which a Partnership Entity is a party (excluding for purposes of this clause 3 of this opinion those agreements and instruments filed or incorporated by reference as an exhibit to Tallgrass Energy’s Annual Report on Form 10-K for the year ended December 31, 2019 and any of Tallgrass Energy’s Current Reports on Form 8-K filed with the Commission since December 31, 2019) (collectively, the “Applicable Agreements”), or to the knowledge of such counsel, results or will result in the creation or imposition of any Lien upon any property or assets of the Partnership Entities under any Applicable Agreement, except for any such violations, breaches, defaults or Liens that, individually or in the aggregate, are not reasonably likely to materially impair the ability of the Partnership to consummate the transactions provided for in this Agreement.

Exhibit B-1

In addition, such counsel shall make statements to the following effect:

I have reviewed the Pricing Disclosure Package and the Offering Memorandum and I or my representatives have participated in conferences with officers and other representatives of the Partnership Entities, with representatives of the Partnership’s independent registered public accounting firm, and with your representatives and your counsel, at which the contents of the Pricing Disclosure Package and the Offering Memorandum and related matters were discussed. I have not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Pricing Disclosure Package and the Offering Memorandum involve matters of a non-legal nature. Accordingly, I am not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Pricing Disclosure Package and the Offering Memorandum (except to the extent stated in paragraph 1). Subject to the foregoing and on the basis of the information I gained in the course of performing the services referred to above, I advise you that nothing came to my attention that caused me to believe that:

it being understood that in each case I have not been asked to, and do not express any belief with respect to (i) the financial statements and schedules or other financial, accounting or reserve information contained or included or incorporated by reference therein or omitted therefrom or (ii) representations and warranties and other statements of fact contained in the exhibits to the documents incorporated by reference therein.
