 Each certificate signed by any officer of the

to a purchaser, be misleading or so that the Offering Memorandum, as amended or supplemented, will comply with applicable law; and (iii) supply any supplemented or amended Offering Memorandum to the Initial Purchasers and Counsel for the
Initial Purchaser, without charge, in such quantities as may be reasonably requested. 
  

 25 








 (d) The Issuers will (i) qualify the Notes and the Guarantees for sale by the
Initial Purchasers under the laws of such jurisdictions as the Initial Purchasers may designate and (ii) maintain such qualifications for so long as required for the sale of the Notes by the Initial Purchasers. The Issuers will promptly advise

securities rating agency has under surveillance or review, with possible negative implications, its rating of the Notes, as soon as the Issuers become aware of any such decrease, notice or public announcement.

other than pursuant to an effective registration statement under the Securities Act or in accordance with Rule 144 under the Securities Act.

 26

offering restrictions requirements of Regulation S. 
 (j) None of the Issuers or any of their Affiliates, nor any person
acting on their behalf (other than the Initial Purchasers or any of their Affiliates, as to which no statement is made), will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any securities of the same or a similar
class as the Notes, other than the Notes offered or sold to the Initial Purchasers hereunder, in a manner which would require the registration under the Securities Act of the Notes. 
 (k) So long as any of the Notes are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, at
any time that either Issuer is not then subject to Section 13 or 15(d) of the Exchange Act, such Issuer will provide at its expense to each holder of the Notes and to each prospective purchaser (as designated by such holder) of the Notes, upon
the request of such holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Securities Act. (This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by
such holders from time to time, of the Notes.) 
 (l) The Issuers will apply the net proceeds from the sale of the Notes as
set forth under “Use of Proceeds” in the Offering Memorandum. 
 (m) Until completion of the distribution, neither
the Issuers nor any of their Affiliates will take, directly or indirectly, any action designed to cause or result in, or which has constituted or which might reasonably be expected to cause or result in, stabilization or manipulation of the price of
any security of the Issuers to facilitate the sale or resale of the Notes. 
 (n) For so long as any Notes are outstanding,
the Issuers and their subsidiaries will conduct their operations in a manner that will not subject the Issuers or any subsidiary to registration as an investment company under the Investment Company Act. 
 (o) Each Note will bear a legend substantially to the following effect until such legend shall no longer be necessary or advisable because
the Notes are no longer subject to the restrictions on transfer described therein: 
 THIS NOTE HAS NOT BEEN REGISTERED UNDER
THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE 

  

 27 








 
REGISTRATION STATEMENT UNDER, OR AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF, THE SECURITIES ACT, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF
ANY STATE OF THE UNITED STATES OR ANY OTHER JURISDICTION AND IN ACCORDANCE WITH THE TRANSFER RESTRICTIONS CONTAINED IN THE INDENTURE UNDER WHICH THIS NOTE WAS ISSUED. 
 (p) The Issuers will not, directly or indirectly, offer, sell, contract to sell or otherwise dispose of any debt securities of the Issuers

the prior written consent of Wachovia. 
 (q) The Issuers will, promptly after they have notified the Initial Purchasers of
any intention by the Issuers to treat the Transactions as being a “reportable transaction” (within the meaning of Treasury Regulation Section 1.6011-4), deliver a duly completed copy of IRS Form 8886 or any successor form to the
Initial Purchasers. 
 5. Expenses. (a) Whether or not the transactions contemplated in this Agreement are consummated or this

incident to the performance of the obligations of the Issuers hereunder for which provision is not otherwise made in this Section. 
 (b) If
the sale of the Notes provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because this Agreement is terminated pursuant to Section 9
hereof or because of any failure, refusal or inability on the part of the Issuers to perform all obligations and satisfy all conditions on their part to be performed or satisfied hereunder other than by reason of a default by the Initial Purchasers,
the Issuers will reimburse the Initial Purchasers upon demand for all reasonable out-of-pocket expenses (including counsel fees and disbursements) that shall have been incurred by it in connection with the proposed purchase and sale of the Notes.

 6. Conditions to the Initial Purchaser’s Obligations. The obligations of the Initial Purchasers to purchase and pay for the
Notes shall be subject to the accuracy of the representations and warranties of the Issuers in Section 1 hereof, in each case as of the date hereof and as of the Closing Date, as if made on and as of the Closing Date, to the accuracy of the
statements of the Issuers’ officers made pursuant to the provisions hereof, to the performance by the Issuers of their covenants and agreements hereunder and to the following additional conditions:

and substance satisfactory to Wachovia, to the effect set forth in Exhibit A hereto. 
 (b) The Initial Purchasers
shall have received such other opinions of counsel, dated the Closing Date, of covering regulatory and local matters as Wachovia shall reasonably request. 
 (c) The Initial Purchaser shall have received an opinion, dated the Closing Date, of Cahill Gordon & Reindel LLP, Counsel for the Initial Purchasers, with respect to the issuance and sale of
the Notes and such other related matters as Wachovia may reasonably require, and the Issuers shall have furnished to such counsel such documents as it may reasonably request for the purpose of enabling it to pass upon such matters. In rendering such
opinion, such counsel may rely as to certain matters of law upon the opinion of Ledgewood referred to in Section 6(a). 
 (d) The Initial Purchasers shall have received on each of the date hereof and the Closing Date (i) a letter, dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to Wachovia and Counsel for
the Initial Purchasers, from Grant Thornton LLP, independent public accountants, and (ii) a letter, 

  

 29 








 
dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to Wachovia and Counsel for the Initial Purchasers from
KPMG LLP, independent public accountants with respect to the Anadarko Assets, in each case containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the
financial statements and certain financial information contained in the Offering Memorandum; provided, however, that the letters referenced in clause (i) shall use a “cut-off date” within three days of the date of such letter.

accident or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree (whether domestic or foreign) otherwise than as set forth in the Offering Memorandum (exclusive of any
amendment or supplement thereto); and (ii) since the respective dates as of which information is given in each Memorandum, there shall not have been any change in the capital stock or long-term debt of any Issuer and its subsidiaries or any
other Guarantor, or any change in or effect on or any development having a prospective change in or effect on the business, operations, properties, assets, liabilities, stockholders’ equity, earnings, condition (financial or otherwise), results
of operations or management of any Issuer and its subsidiaries or any other Guarantor, whether or not in the ordinary course of business, otherwise than as set forth in each such Memorandum (exclusive of any amendment or supplement thereto), the
effect of which, in any such case described in clause (i) or (ii), is, in the sole judgment of Wachovia, so material and adverse as to make it impracticable or inadvisable to market the Notes on the terms and in the manner described in the
Offering Memorandum (exclusive of any amendment or supplement thereto). 
 (f) None of the information set forth in the
sections of the Offering Memorandum, or documents incorporated by reference therein, entitled “Offering Memorandum Summary—Recent Developments,” “Use of Proceeds,” “Capitalization,” “Executive

 7. Indemnification and Contribution. (a) Each Issuer and each Guarantor, jointly and severally, agrees to indemnify and hold harmless each Initial Purchasers, their affiliates, directors and officers and each person, if any, who
controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) such Initial Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Initial Purchaser or such other
person may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the
Preliminary Memorandum, the Offering Memorandum or any amendment or supplement thereto; or (ii) the omission or alleged omission to state in the Preliminary Memorandum, the Offering Memorandum, the Final Memorandum or any amendment or
supplement thereto and each Issuer Supplemental Disclosure Document or any amendment or supplement thereto a material fact necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, and will
reimburse, as incurred, such Initial Purchaser and each such other person for any legal or other expenses reasonably incurred by such Initial Purchaser or such other person in connection with investigating, defending against or appearing as a
third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, that the Issuers and the Guarantors 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 untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Memorandum, the Offering Memorandum or any amendment or supplement thereto, in reliance upon and in
conformity with written information relating to such Initial Purchaser furnished to the Issuers by such Initial Purchaser through Wachovia specifically for use therein as set forth in Section 11 hereof. 
 (b) The Initial Purchasers will, severally and not jointly, indemnify and hold harmless the Issuers and the Guarantors and their respective affiliates,
directors, officers, and each person, if any, who controls any of the Issuers or the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to
which the Issuers, the Guarantors, any such affiliates, directors or officers or such controlling person may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact contained in the Preliminary Memorandum or any amendment or supplement thereto, or (ii) the omission or alleged omission to state in the Preliminary Memorandum, or
the Offering Memorandum or any amendment or supplement thereto a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information 

  

 32 








 
furnished to the Issuers by the Initial Purchaser specifically for use therein as set forth in Section 11 hereof and, subject to the limitation set
forth immediately preceding this clause, will reimburse as incurred, any legal or other expenses reasonably incurred by the Issuers or the Guarantors or any such affiliates, directors or officers or such controlling person in connection with
investigating, defending against or appearing as a third-party witness in connection with, any such loss, claim, damage, liability or action in respect thereof. 
 (c) Promptly after receipt by any person to whom indemnity may be available under this Section 7 (the “indemnified party”) of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any person from whom indemnity may be sought under this Section 7 (the “indemnifying party”), notify such indemnifying party of the commencement thereof; provided,
however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced by such failure and, provided further, that the
failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. In case any such action is brought against any indemnified party, and such
indemnified party notifies the relevant indemnifying party of the commencement thereof, such indemnifying party will be entitled to participate therein and, to the extent that it may wish, to assume the defense thereof, jointly with any other
indemnifying party similarly notified, with counsel satisfactory to such indemnified party; provided, however, that if the named parties in any such action (including impleaded parties) include both the indemnified party and the indemnifying party
and the indemnified party shall have concluded, based on advice of outside counsel, that there may be one or more legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the
indemnifying party or that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, the indemnifying party shall not have the right to direct the defense of such action on
behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from an indemnifying party to an
indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, such indemnifying party will not be liable to such indemnified party under this Section 7 for
any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) such indemnified party shall have employed separate counsel in
accordance with the proviso to the immediately preceding sentence or (ii) such indemnifying party does not promptly retain counsel satisfactory to such indemnified party or (iii) such indemnifying party has authorized the employment of
counsel for such indemnified party at the expense of the indemnifying party. After such notice from an indemnifying party to an indemnified party, such indemnifying party will not be liable for the costs and expenses of any settlement of such action
effected by such indemnified party without the written consent of such indemnifying party. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for


  

 33 








 
fees and expenses of counsel as contemplated by (i), (ii) or (iii) of the third sentence of this paragraph, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its written consent if (x) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (y) such indemnifying
party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. An indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent
to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which indemnification may be sought hereunder (whether or not the indemnified party or any other person that may be entitled to indemnification
hereunder is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of the indemnified party and such other persons from all liability arising out of such claim, action,
suit or proceeding. 
 (d) (i) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this
Section 7 is unavailable or insufficient, for any reason, to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (including, without limitation, any legal or other expenses incurred in connection with
defending or investigating any action or claim) (or actions in respect thereof) (“Losses”), the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, in order to provide for just and equitable
contribution, agree to contribute to the amount paid or payable by such indemnified party as a result of such Losses to which the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, may be subject, in such
proportion as is 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 the
foregoing clause (i) is unavailable for any reason, not only such relative benefits but also the relative fault of the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, in connection with the statements or
omissions or alleged statements or omissions that resulted in such Losses. The relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, shall be deemed to be in the same proportion as
the total proceeds from the offering (before deducting expenses) received by the Issuers bear to the total discounts and commissions received by the Initial Purchasers from the Issuers in connection with the purchase of the Notes hereunder as set
forth in the Offering Memorandum. The relative fault of the parties 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 Issuers, the Guarantors or the Initial Purchasers, the parties’ intent, relative knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances. The Issuers, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or by any other method of
allocation that does not take into account the equitable considerations referred to above. Notwithstanding any other provision of this paragraph (d), the Initial Purchasers shall not be obligated to make 

  

 34 








 
contributions hereunder that in the aggregate exceed the total underwriting discounts and commissions received by the Initial Purchasers from the Issuers in
connection with the purchase of the Notes hereunder, and 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. For purposes of this paragraph (d), each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each other person listed
in Section 7(a) hereof shall have the same rights to contribution as an Initial Purchaser, and each affiliate, director or officer of the Issuers or any Guarantor and each person, if any, who controls the Issuers within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Issuers and the Guarantors. 
 (e) The obligations of the Issuers and the Guarantors under this Section 7 shall be in addition to any obligations or liabilities which the Issuers and the Guarantors may otherwise have and the obligations of the
Initial Purchasers under this Section 7 shall be in addition to any obligations or liabilities which the Initial Purchasers may otherwise have. 
 8. Survival. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Issuers, the Guarantors, their respective officers, and the Initial Purchasers set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Issuers, the Guarantors, their respective
officers or directors or any controlling person referred to in Section 7 hereof or the Initial Purchasers and (ii) delivery of and payment for the Notes. The respective agreements, covenants, indemnities and other statements set forth in
Sections 5, 7 and Sections 10-15 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 
 9. Termination. (a) The Initial Purchasers may terminate this Agreement with respect to the Notes by notice to the Issuers at any time on or prior to the Closing Date in the event that the Issuers shall have failed, refused or
been unable to perform in any material respect all obligations and satisfy in any material respect all conditions on their part to be performed or satisfied hereunder at or prior thereto or if, at or prior to the Closing Date (i) trading in
securities generally on the New York Stock Exchange, the NASDAQ National Market or in the over-the-counter market, or trading in any securities of the Issuers on any exchange or in the over-the-counter market, shall have been suspended or minimum or
maximum prices shall have been established on any such exchange or market; (ii) there has been a material disruption in commercial banking or securities settlement, payment or clearance services in the United States; (iii) a banking
moratorium shall have been declared by New York, North Carolina or United States authorities or (iv) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power, (B) an outbreak
or escalation of any other insurrection or armed conflict involving the United States, (C) the occurrence of any other calamity or crisis involving the United States or (D) any change in general economic, political or financial conditions
which has an effect on the U.S. financial markets that, in the 

  

 35 








 
case of any event described in this clause (iv), in the sole judgment of Wachovia, makes it impracticable or inadvisable to proceed with the offer, sale and
delivery of the Notes as disclosed in the Preliminary Memorandum or the Offering Memorandum, exclusive of any amendment or supplement thereto. 
 (b) Termination of this Agreement pursuant to this Section 9 shall be without liability of any party to any other party except as provided in Sections 5 and 7 hereof. 
 10. Information Supplied by Initial Purchasers. The statements set forth in the second and fourth sentences of the third paragraph, the second
sentence of the fifth paragraph and the seventh, eighth, ninth and tenth paragraphs under the heading “Plan of Distribution” in the Preliminary Memorandum and the Offering Memorandum, to the extent such statements relate to the Initial
Purchasers, constitute the only information furnished by the Initial Purchasers to the Issuers for the purposes of Sections 1(a) and 7 hereof. 
 11. Notices. All communications hereunder shall be in writing and, if sent to any of the Initial Purchasers, shall be delivered or sent by mail, telex or facsimile transmission and confirmed in writing to Wachovia Capital Markets,
LLC, One Wachovia Center, 301 South College Street, Charlotte, North Carolina 28288-0604, Attention: Jay Braden, with a copy to Cahill Gordon & Reindel LLP, 80 Pine Street, New York, New York 10005, Attention: Noah B. Newitz,
and if sent to the Issuers, shall be delivered or sent by mail, telex or facsimile transmission and confirmed in writing to the Issuers at Atlas Pipeline Partners, L.P., Westpointe Corporate Center One, 1550 Coraopolis Heights, Moon Township,
Pennsylvania 15108, Attention: Michael L. Staines, with a copy to Ledgewood, 1900 Market Street, Suite 750, Philadelphia, Pennsylvania 19103, Attention: Lisa A Ernst. 
 12. Successors. This Agreement shall inure to the benefit of and shall be binding upon the Initial Purchasers, the Issuers and the Guarantors and their respective successors and legal representatives, and
nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained, this Agreement and
all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of the Initial Purchasers, the Issuers and the Guarantors and their respective successors and legal representatives, and for the benefit of no
other person, except that (i) the indemnities of the Issuers contained in Section 7 of this Agreement shall also be for the benefit of any person or persons who control an Initial Purchaser within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act and (ii) the indemnities of the Initial Purchasers contained in Section 7 of this Agreement shall also be for the benefit of the affiliates, directors and officers of the Issuers and
the Guarantors, and any person or persons who control the Issuers or the Guarantors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act. No purchaser of Notes from an Initial Purchasers shall be deemed
a successor to such Initial Purchaser because of such purchase. 
  

 36 








 13. Applicable Law. This Agreement shall be governed by the laws of the State of New York.

 14. Submission to Jurisdiction and Service of Process; Waiver of Jury Trial. (a) Any claim, counterclaim or dispute of any
kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, may be commenced, prosecuted or continued in any court of the State of New York located in the City and County of
New York or in the United States District Court for the Southern District of New York, which courts shall have non-exclusive jurisdiction over the adjudication of such matters, and each Issuer, each Initial Purchaser and each of the Subsidiaries and
Guarantors consents to the non-exclusive jurisdiction of such courts and personal service with respect thereto. 
 (b) Each party agrees that
any service of process or other legal summons in connection with any Proceeding may be served on it by mailing a copy thereof by registered mail, or a form of mail substantially equivalent thereto, postage prepaid, addressed to the served party at
its address as provided for in Section 11 hereof. Nothing in this Section shall affect the right of the parties to serve process in any other manner permitted by law. 
 (c) Each Issuer (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders, partners and affiliates), each Initial
Purchaser and each of the Subsidiaries and Guarantors waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. Each Issuer
and each of the Subsidiaries and Guarantors agree that a final judgment in any such proceeding brought in any such court shall be conclusive and binding upon it and may be enforced in any other courts in the jurisdiction of which it is or may be
subject, by suit upon such judgment. 
 15. Defaulting Initial Purchasers. If, on the Closing Date, any Initial Purchaser defaults in
the performance of its obligations under this Agreement, the non-defaulting Initial Purchasers shall be obligated to purchase the Notes that such defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on the Closing Date
(the “Remaining Notes”) in the respective proportions that the principal amount of the Notes set opposite the name of each non-defaulting Initial Purchaser in Schedule I hereto bears to the total number of the Notes set opposite the
names of all the non-defaulting Initial Purchasers in Schedule I hereto; provided, however, that the non-defaulting Initial Purchasers shall not be obligated to purchase any of the Notes on the Closing Date if the total amount of Notes
which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds 10% of the total amount of Notes to be purchased on the Closing Date. If the foregoing maximum is exceeded, the non-defaulting Initial
Purchasers, or those other purchasers satisfactory to the Initial Purchasers who so agree, shall have the right, but not the obligation, to purchase, in such proportion as may be agreed upon among them, all the Remaining Notes. If the non-defaulting
Initial Purchasers or other Initial Purchasers satisfactory to the Initial Purchasers do not elect to purchase the Remaining Notes, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or the Issuers,
except that the Issuers will continue to be liable for the payment of expenses to the extent set forth herein. 
  

 37 








 Nothing contained in this Agreement shall relieve a defaulting Initial Purchaser of any liability it may
have to the Issuers for damages caused by its default. If other purchasers are obligated or agree to purchase the Notes of a defaulting or withdrawing Initial Purchaser, the Issuers or Wachovia may postpone the Closing Date for up to five full
business days in order to effect any changes in the Transaction Documents or in any other document or arrangement that, in the opinion of counsel for the Issuers or Counsel for the Initial Purchasers, may be necessary. 
 16. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together
shall constitute one and the same instrument.

 B. The Finance Co has been duly incorporated and
is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation. 
 C. The Partnership is duly
qualified to do business and is in good standing under the laws of each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except where the failure to so qualify or be in good
standing would not have a Material Adverse Effect. 
 D. The Partnership has full partnership power to own or lease its properties and
conduct its business as described in the Offering Memorandum, to enter into the Transaction Documents and to carry out its obligations thereunder. 
 E. Each subsidiary of the Partnership and each other Guarantor has been duly organized, is validly existing as a limited liability company or limited partnership in good standing under the laws of the jurisdiction of its formation, has the
entity power and authority to own its property and to conduct its business as described in the Offering Memorandum and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its
ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a Material Adverse Effect; all of the issued equity interests of each subsidiary of the

the Pennsylvania Limited Liability Company Act, the Arkansas Limited Liability Company Act, the Texas Limited Partnership Act or the Oklahoma Limited Liability Company Act. 
 F. To such counsel’s best knowledge such counsel does not know of any legal or governmental proceedings pending or threatened to which the

 H. Each of the Indenture and the Registration Rights Agreement has been duly authorized, executed and delivered by, and is a
valid and binding agreement of, each Issuer and each Guarantor party thereto, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and general principles of

when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of the Purchase Agreement, will be valid and binding obligations of the Issuers,
enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and general principles of equity, and will be entitled to the benefits of the Indenture and the
Registration Rights Agreement. 
 K. The Exchange Notes have been duly authorized by the Issuers and, if any are issued, when executed and
authenticated in accordance with the provisions of the Indenture and Registration Rights Agreement and delivered to the noteholders in exchange for the Notes in accordance with the terms of the Registration Rights Agreement, will be valid and
binding obligations of the Issuers, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and general principles of equity, and will be entitled to the
benefits of the Indenture and the Registration Rights Agreement. 
 L. The statements in the Offering Memorandum under the captions
“Risk Factors — The covenants in the indenture governing the notes impose, and covenants contained in agreements governing indebtedness we incur in the future may impose, restrictions that may limit our operating and financial
flexibility,” “Risk Factors — The subsidiary guarantees could be deemed fraudulent conveyances under certain circumstances, and a court may try to subordinate or void the subsidiary guarantees,” “Description of Other
Indebtedness,” “Description of Notes,” “Exchange Offer; Registration Rights” and “Notice to Investors” and the statements in the documents incorporated by reference in the Offering Memorandum under the captions
“Business”, “Directors and Executive Officers of the Registrant,” “Executive Compensation,” “Certain Relationships and Related Transactions,” insofar as such statements constitute summaries of legal matters or
documents, fairly summarize in all material respects such matters or documents. 
  

 Ex. A-2 








 M. The statements in the Offering Memorandum under the caption “Material United States Federal
Income Tax Consequences,” insofar as such statements constitute a summary of the United States federal tax laws referred to therein, are accurate and fairly summarize in all material respects the United States federal tax laws referred to
therein. 
 N. Based upon the representations, warranties and agreements of the Issuers in Sections 1(hhh), (iii), 1(jjj) and 1(kkk), 4(g),
4(h), 4(i) and 4(j) of the Purchase Agreement and of the Initial Purchasers in Section 3 of the Purchase Agreement, it is not necessary in connection with the offer, sale and delivery of the Notes to the Initial Purchasers under the Purchase
Agreement or in connection with the initial resale of such Notes by the Initial Purchasers in accordance with Section 3 of the Purchase Agreement to register the Notes under the Securities Act of 1933 or to qualify the Indenture under the Trust
Indenture Act of 1939, it being understood that no opinion is expressed as to any subsequent resale of any Notes. 
 O. The execution and
delivery by each Issuer of, and the performance by each Issuer and each Guarantor of its obligations under, the Purchase Agreement, the Registration Rights Agreement and the Notes will not contravene the certificate of incorporation, operating
agreement or by-laws of any Issuer or any provision of applicable law or any agreement or other instrument binding upon any Issuer or any of its subsidiaries or any judgment, order or decree of any governmental body, agency or court having
jurisdiction over any Issuer or any of its subsidiaries, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Issuers and their respective subsidiaries and
each other Guarantor of their respective obligations under the Purchase Agreement, the Registration Rights Agreement or the Notes, except such as may be required by the securities or Blue Sky laws of the various states in connection with the offer
and sale of the Notes and by Federal and state securities laws with respect to the obligations of the Issuers and the Guarantors under the Registration Rights Agreement. 
 P. None of the Issuers nor any Guarantor is, nor after giving effect to the offering and sale of the Notes and the application of the proceeds thereof as described in the Offering Memorandum will be, an
“investment company,” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended. 
 Q. The Preliminary Memorandum and the Offering Memorandum comply as to form in all material respects with requirements of Form S-3 under the Securities
Act of 1933 (except for the financial statements and notes and financial schedules and other financial and accounting data contained or incorporated by reference therein, as to which such counsel expresses no opinion). To the best knowledge of such
counsel, there are no contracts or other documents that would be required by the Securities Act to be disclosed in a prospectus were the Notes being issued and sold in a public offering registered on Form S-3 under the Securities Act that are not so
disclosed in the Preliminary Memorandum or the Offering Memorandum. 
 R. The documents incorporated or deemed to be incorporated by
reference in the Offering Memorandum at the time they were filed with the Commission complied as to form in all material respects with the requirements of the Exchange Act and the rules and regulations of the Commission promulgated thereunder.

  

 Ex. A-3 








 In addition, Ledgewood, P.C. shall include in its opinion or a separate letter the following language:

 In our capacity as counsel to the Issuers, we have examined a copy of the Offering Memorandum (including the documents
incorporated by reference therein). We have also reviewed and participated in discussions concerning the preparation of the Preliminary Memorandum and the Offering Memorandum with certain officers and employees of the Partnership, with its auditors
and with representatives of and counsel to the Initial Purchasers. The limitations inherent in the independent verification of factual matters and in the role of outside counsel are such, however, that we cannot and do not assume any responsibility
for the accuracy, completeness or fairness of any of the statements made in the Offering Memorandum, except as set forth in paragraphs L and M of our opinion addressed to you, dated the date hereof. 
 Subject to the limitations set forth in the immediately preceding paragraph, we advise you that, on the basis of the information we gained
in the course of performing the services referred to above, no facts came to our attention which give us reason to believe that the Offering Memorandum (including the documents incorporated by reference therein) (other than the financial statements
and schedules and other financial data included therein or omitted therefrom, as to which we have not been requested to express a view) as of the Time of Sale and as of the date hereof and the Final Memorandum (other than the financial statements
and schedules and other financial data included therein or omitted therefrom, as to which we have not been requested to express a view), as of its date or the date hereof, contained or contains 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.
