or procedures), trademarks, service marks and trade names currently employed by
them in connection with the business now operated by them, except where the
failure to so own or possess would not, individually or in the aggregate, have a
Material Adverse Effect, and neither the Company nor any of its subsidiaries has
received any notice of infringement of or conflict with asserted rights of
others with respect to any of the foregoing, which, individually or in the
aggregate, if the subject of an unfavorable decision, ruling or finding, would
reasonably be expected to have a Material Adverse Effect.

     (dd) Disclosure Controls. The Company and its subsidiaries maintain a
system of “disclosure controls and procedures” (as defined in Rule 13a-15(e) of

Act is recorded, processed, summarized and reported within the time periods
specified in the Commission’s rules and forms, including controls and procedures
designed to ensure that such information is accumulated and communicated to the
Company’s management as appropriate to allow timely decisions regarding required
disclosure. The Company and its subsidiaries have carried out evaluations of the
effectiveness of their disclosure controls and procedures as required by
Rule 13a-15 of the Exchange Act.
     (ee) Accounting Controls. The Company and its subsidiaries maintain a
system of “internal control over financial reporting” (as defined in
Rule 13a-15(f) of the Exchange Act) that comply with the requirements of the
Exchange Act and have been designed by, or under the supervision of, their
respective principal executive and principal financial officers, or persons
performing similar functions, to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements
for external purposes in accordance with GAAP. The Company and its subsidiaries
(A) make and keep books, records and accounts, which, in reasonable detail,
accurately and fairly reflect the transactions and

to believe that there has been any material weakness in the Company’s internal
control over financial reporting (whether or not remediated) and (ii) there has
been no change in the Company’s internal control over financial reporting that
has materially affected, or is reasonably likely to materially affect, the
Company’s internal control over financial reporting.
     (ff) Insurance. The Company and each of its subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as are prudent and customary in the businesses in which they
are engaged; neither the Company nor any of its subsidiaries has been refused
any insurance coverage sought or applied for; and neither the Company nor any of
its subsidiaries has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not have a Material Adverse Effect, except as
described in each of the Time of Sale Information and Offering Memorandum.

its subsidiaries conduct business, the rules and regulations thereunder and any
related or similar rules, regulations or guidelines, issued, administered or
enforced by any governmental agency (collectively, the “Money Laundering Laws”)

agent, employee or affiliate of the Company or any of its subsidiaries is
currently subject to any U.S. sanctions administered

13

(after giving effect to the issuance of the Securities and the other
transactions related thereto as described in each of the Time of Sale
Information and the Offering Memorandum) will be Solvent. As used in this
paragraph, the term “Solvent” means, with respect to a particular date, that on
such date (i) the present fair market value (or present fair saleable value) of
the assets of the Company is not less than the total amount required to pay the
liabilities of the Company on its total existing debts and liabilities

liabilities beyond its ability to pay as such debts and liabilities mature;

propose to engage in any business or transaction, for which its property would

other distribution on such subsidiary’s equity securities or similar ownerships
interest, from repaying to the Company any loans or advances to such subsidiary
from the Company or from transferring any of such subsidiary’s properties or
assets to the Company or any other subsidiary of the Company.
     (ll) No Broker’s Fees. Neither the Company nor any of its subsidiaries is a

finder’s fee or like payment in connection with the offering and sale of the
Securities.
     (mm) Rule 144A Eligibility. On the Closing Date, the Securities will not be
of the same class as securities listed on a national securities exchange
registered under Section 6 of the Exchange Act or quoted on an automated
inter-dealer quotation system; and each of the Preliminary Offering Memorandum

of any form of general solicitation or general advertising within the meaning of
Rule 502(c) of Regulation D or in any manner involving a public offering within
the meaning of Section 4(2) of the Securities Act or (ii) engaged in any
directed selling efforts within the meaning of Regulation S under the Securities
Act (“Regulation S”), and all such persons have complied with the offering
restrictions requirement of Regulation S. The sale of the Securities pursuant to
Regulation S is not part of a plan or scheme to evade the registration
provisions of the Securities Act.
     (pp) Securities Law Exemptions. Assuming the accuracy of the
representations and warranties of the Initial Purchasers contained in
Section 1(b) (including Annex C hereto) and their compliance with their
agreements set forth therein, it is not necessary, in connection with the
issuance and sale of the Securities to the Initial Purchasers and the offer,
resale and delivery of the Securities by the Initial Purchasers in the manner
contemplated by this Agreement, the Time of Sale Information and the Offering

     (c) No Material Adverse Change. Subsequent to the execution and delivery of
this Agreement, no event or condition of a type described in Section 3(e) hereof
shall have occurred or shall exist, which event or condition is not described in
each of the Time of Sale Information (excluding any amendment or supplement
thereto) and the Offering Memorandum (excluding any amendment or supplement
thereto) the effect of which in the judgment of the Representative makes it
impracticable or inadvisable to proceed with the offering, sale or delivery of
the Securities on the terms and in the manner contemplated by this Agreement,
the Time of Sale Information and the Offering Memorandum.
     (d) Officers’ Certificate. The Representative shall have received on and as
of the Closing Date a certificate of two executive officers of the Company and
of each Guarantor who have specific knowledge of the Company’s or such
Guarantor’s financial matters and is satisfactory to the Representative
(i) confirming that such officers have carefully reviewed the Time of Sale
Information and the Offering Memorandum and, to the best knowledge of each such
officer, the representations set forth in Sections 3(a), 3(b) and 3(c) hereof
are true and correct, (ii) confirming that the other representations and
warranties of the Company and the Guarantors in this Agreement are true and
correct and that the Company and the Guarantors have complied with all
agreements and satisfied all conditions on their part to be performed or
satisfied hereunder at or prior to the Closing Date, (iii) to the effect set
forth in paragraphs (b) and (c) above and (iv) that, to the knowledge of each
such officer, the statements of the Company and its officers made in any
certificates delivered pursuant to this Agreement are true and correct on and as
of the Closing Date.

PricewaterhouseCoopers LLP shall have furnished to the Representative, at the
request of the Company, letters, dated the respective dates of delivery thereof

substance reasonably satisfactory to the Representative, containing statements
and information of the type customarily included in accountants’ “comfort
letters” to underwriters with respect to the financial statements and certain
financial information of the Company and its subsidiaries contained or
incorporated by reference in each of the Time of Sale Information and the
Offering Memorandum; provided that the letter delivered on the date of this
Agreement and the Closing Date shall use a “cut-off” date no more than three
business days prior to such date.
     (f) Reserve Engineer Letters. The Representative shall have received, on
each of the date hereof and the Closing Date, a letter dated the date hereof or
the Closing Date, as the case may be, in form and substance satisfactory to the
Representative, from each of the Reserve Engineers, letters containing
statements and information ordinarily included in reserve engineers’ “comfort
letters” with respect to the applicable reserve reports and related information
contained or incorporated by reference in the Time of Sale Information or the
Offering Memorandum.

Representative shall have received the written opinion and 10b-5 statement,
dated the Closing Date and addressed to the Initial Purchasers, from Vinson &
Elkins L.L.P., counsel for the Company and the Guarantors, in substantially the
form set forth as Exhibit B and in form and substance reasonably satisfactory to
the Representative and counsel for the Initial Purchasers.
     (h) Opinion and 10b-5 Statement of Counsel for the Initial Purchasers. The
Representative shall have received on and as of the Closing Date an opinion and
10b-5 statement of Andrews Kurth LLP, counsel for the Initial Purchasers, with
respect to such matters as the Representative may reasonably request, and such
counsel shall have received such documents and information as they may
reasonably request to enable them to pass upon such matters.
     (i) No Legal Impediment to Issuance. No action shall have been taken and no

issuance of the Guarantees; and no injunction or order of any federal, state or
foreign court shall have been issued that would, as of the Closing Date, prevent
the issuance or sale of the Securities or the issuance of the Guarantees.
     (j) Good Standing. The Representative shall have received on and as of the
Closing Date satisfactory evidence of the good standing of the Company and its
subsidiaries in their respective jurisdictions of organization and their
qualification and good standing in such other jurisdictions in which the conduct
of the Company’s and its subsidiaries’ business or ownership or leasing of
property or assets requires such qualification, in each case in writing or any
standard form of telecommunication, from the appropriate governmental
authorities of such jurisdictions.

21

--------------------------------------------------------------------------------

 

     (k) Indenture. The Company, the Guarantors and the Trustee shall have

provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Initial Purchasers.
     7. Indemnification and Contribution.
     (a) Indemnification of the Initial Purchasers. The Company and each of the
Guarantors jointly and severally agree to indemnify and hold harmless each
Initial Purchaser, its affiliates who have, or who are alleged to have,
participated in the distribution of Securities, 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, and the
successors and assigns of all the foregoing persons, from and against any and
all losses, claims, damages and liabilities (including, without limitation,
legal fees and other expenses incurred in connection with any suit, action or
proceeding or any claim asserted, as such fees and expenses are incurred), joint
or several, that arise out of, or are based upon, any untrue statement or
alleged untrue statement of a material fact contained or incorporated by
reference in the Preliminary Offering Memorandum, any of the other Time of Sale
Information, any Issuer Written Communication or the Offering Memorandum (or any
amendment or supplement thereto) or any omission or alleged omission to state
therein a material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading, in
each case except insofar as such losses, claims, damages or liabilities arise
out of, or are based upon, any untrue statement or omission or alleged untrue
statement or omission made in reliance upon and in conformity with any
information relating to any Initial Purchaser furnished to the Company in
writing by such Initial Purchaser through the Representative expressly for use
therein, it being understood and agreed that the only such information furnished
by any Initial Purchaser consists of the information described as such in
paragraph (b) below.
     (b) Indemnification of the Company. Each Initial Purchaser agrees,
severally and not jointly, to indemnify and hold harmless the Company, each of
the Guarantors, each of their respective directors and officers and each person,
if any, who controls the Company or any of the Guarantors (within the meaning of
Section 15 of the Securities Act or Section 20 of the

22

--------------------------------------------------------------------------------

 

Exchange Act) to the same extent as the indemnity set forth in paragraph (a)
above, but only with respect to any losses, claims, damages or liabilities that
arise out of, or are based upon, any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with any
information relating to such Initial Purchaser furnished to the Company in
writing by such Initial Purchaser through the Representative expressly for use
in the Preliminary Offering Memorandum, any of the other Time of Sale
Information, any Issuer Written Communication or the Offering Memorandum (or any
amendment or supplement thereto), it being understood and agreed that the only
such information consists of the following: the information contained in the
third and fourth sentences of the tenth paragraph and the twelfth paragraph,
respectively, under the caption “Plan of distribution” in the Preliminary
Offering Memorandum and the Offering Memorandum.
     (c) Notice and Procedures. If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be brought or
asserted against any person in respect of which indemnification may be sought
pursuant to either paragraph (a) or (b) above, such person (the “Indemnified
Person”) shall promptly notify the person against whom such indemnification may
be sought (the “Indemnifying Person”) in writing; provided that the failure to
notify the Indemnifying Person shall not relieve it from any liability that it
may have under paragraph (a) or (b) above except to the extent that 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 Person shall not relieve it from any liability that it may have to
an Indemnified Person otherwise than under paragraph (a) or (b) above. If any
such proceeding shall be brought or asserted against an Indemnified Person and
it shall have notified the Indemnifying Person thereof, the Indemnifying Person
shall retain counsel reasonably satisfactory to the Indemnified Person (who
shall not, without the consent of the Indemnified Person, be counsel to the
Indemnifying Person) to represent the Indemnified Person and any others entitled
to indemnification pursuant to this Section 7 that the Indemnifying Person may
designate in such proceeding and shall pay the fees and expenses of such
proceeding and shall pay the fees and expenses of such counsel related to such
proceeding, as incurred. In any such proceeding, any Indemnified Person shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed in
writing to the contrary; (ii) the Indemnifying Person has failed within a
reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person; (iii) the Indemnified Person shall have reasonably concluded that there
may be legal defenses available to it that are different from or in addition to
those available to the Indemnifying Person; or (iv) the named parties in any
such proceeding (including any impleaded parties) include both the Indemnifying
Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. It is understood and agreed that the Indemnifying Person shall
not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the reasonably incurred fees and expenses of more
than one separate firm (in addition to any local counsel) for all Indemnified
Persons, and that all such fees and expenses shall be paid or reimbursed as they
are incurred. Any such separate firm for any Initial Purchaser, its affiliates,
directors and officers and any control persons of such Initial Purchaser shall
be designated in writing by J.P. Morgan Securities LLC and any such separate
firm for the Company, the Guarantors, their respective directors and officers
and any control persons of the Company and the Guarantors shall be designated in

23

--------------------------------------------------------------------------------

 

writing by the Company. The Indemnifying Person shall not be liable for any
settlement of any proceeding effected without its written consent (which shall
not be unreasonably withheld), but if settled with such consent or if there be a
final judgment for the plaintiff, the Indemnifying Person agrees to indemnify
each Indemnified Person from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an Indemnified Person shall have requested that an Indemnifying Person reimburse
the Indemnified Person for fees and expenses of counsel as contemplated by this
paragraph (c), the Indemnifying Person 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 the Indemnifying Person of such
request and (ii) the Indemnifying Person shall not have reimbursed the
Indemnified Person in accordance with such request prior to the date of such
settlement. No Indemnifying Person shall, without the written consent of the
Indemnified Person (which shall not be unreasonably withheld), effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Person is or could have been a party and indemnification could have
been sought hereunder by such Indemnified Person, unless such settlement
(x) includes an unconditional release of such Indemnified Person, in form and
substance reasonably satisfactory to such Indemnified Person, from all liability
on claims that are the subject matter of such proceeding and (y) does not
include any statement as to or any admission of fault, culpability or a failure
to act by or on behalf of any Indemnified Person.
     (d) Contribution. If the indemnification provided for in paragraphs (a) and
(b) above is unavailable to an Indemnified Person or insufficient in respect of
any losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Guarantors on the one hand and the
Initial Purchasers on the other from the offering of the Securities 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 Company and
the Guarantors on the one hand and the Initial Purchasers on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Guarantors
on the one hand and the Initial Purchasers on the other shall be deemed to be in
the same respective proportions as the net proceeds (before deducting expenses)
received by the Company from the sale of the Securities and the total discounts
and commissions received by the Initial Purchasers in connection therewith, as
provided in this Agreement, bear to the aggregate offering price of the
Securities. The relative fault of the Company and the Guarantors on the one hand
and the Initial Purchasers on the other 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 Company or any Guarantor or by the Initial
Purchasers and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.
     (e) Limitation on Liability. The Company, the Guarantors and the Initial
Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 7 were determined by pro rata allocation (even if the
Initial Purchasers were treated as one entity for

24

--------------------------------------------------------------------------------

 

such purpose) or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an Indemnified Person as a result of the losses, claims, damages
and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred
by such Indemnified Person in connection with any such action or claim.
Notwithstanding the provisions of this Section 7, in no event shall an Initial
Purchaser be required to contribute any amount in excess of the amount by which
the total discounts and commissions received by such Initial Purchaser with
respect to the offering of the Securities exceeds the amount of any damages that
such Initial Purchaser has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Initial Purchasers’
obligations to contribute pursuant to this Section 7 are several in proportion
to their respective purchase obligations hereunder and not joint.
     (f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are
not exclusive and shall not limit any rights or remedies that may otherwise be
available to any Indemnified Person at law or in equity.
     8. Termination. This Agreement may be terminated in the absolute discretion
of the Representative, by notice to the Company, if after the execution and
delivery of this Agreement and on or prior to the Closing Date (i) trading
generally shall have been suspended or materially limited, or minimum or maximum
prices for trading have been fixed, or maximum ranges for prices have been
required, on or by any of the New York Stock Exchange, the Nasdaq Global Select
Market or the over-the-counter market; (ii) trading of any securities issued or
guaranteed by the Company or any of the Guarantors shall have been suspended on
any exchange or in any over-the-counter market; (iii) a material disruption in
securities settlement, payment or clearance services in the United States shall
have occurred; (iv) a general moratorium on commercial banking activities shall
have been declared by federal or New York State authorities; (v) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis, either within or outside the United
States, that, in the judgment of the Representative, is material and adverse and
makes it impracticable or inadvisable to proceed with the offering, sale or
delivery of the Securities on the terms and in the manner contemplated by this
Agreement, the Time of Sale Information and the Offering Memorandum; or
(vi) there has been, since the time of execution of this Agreement or since the
respective dates as of which information is given in the Time of Sale
Information or the Offering Memorandum, any change in the condition, financial
or otherwise, or in the earnings, business affairs or business prospects of the
Company and its subsidiaries, taken as a whole, whether or not arising in the
ordinary course of business, that, in the judgment of the Representative, is
material and adverse and makes it impracticable or inadvisable to proceed with
the offering, sale or delivery of the Securities on the terms and in the manner
contemplated by this Agreement, the Time of Sale Information and the Offering
Memorandum.

25

--------------------------------------------------------------------------------

 

     9. Defaulting Initial Purchaser.
     (a) If, on the Closing Date, any Initial Purchaser defaults on its
obligation to purchase the Securities that it has agreed to purchase hereunder,
the non-defaulting Initial Purchasers may in their discretion arrange for the
purchase of such Securities by other persons satisfactory to the Company 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 Securities, then the Company 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 Securities on such terms. If
other persons become obligated or agree to purchase the Securities of a
defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or
the Company may postpone the Closing Date for up to five full business days in
order to effect any changes that in the opinion of counsel for the Company or
counsel for the Initial Purchasers may be necessary in the Time of Sale
Information, the Offering Memorandum or in any other document or arrangement,
and the Company agrees to promptly prepare any amendment or supplement to the
Time of Sale Information 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 otherwise requires, any person
not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases
Securities that a defaulting Initial Purchaser agreed but failed to purchase.
     (b) If, after giving effect to any arrangements for the purchase of the
Securities of a defaulting Initial Purchaser or Initial Purchasers by the
non-defaulting Initial Purchasers and the Company as provided in paragraph (a)
above, the aggregate principal amount of such Securities that remains
unpurchased does not exceed one-eleventh of the aggregate principal amount of
all the Securities, then the Company shall have the right to require each
non-defaulting Initial Purchaser to purchase the principal amount of Securities
that such Initial Purchaser agreed to purchase hereunder plus such Initial
Purchaser’s pro rata share (based on the principal amount of Securities that
such Initial Purchaser agreed to purchase hereunder) of the Securities of such
defaulting Initial Purchaser or Initial Purchasers for which such arrangements
have not been made.
     (c) If, after giving effect to any arrangements for the purchase of the
Securities of a defaulting Initial Purchaser or Initial Purchasers by the
non-defaulting Initial Purchasers and the Company as provided in paragraph (a)
above, the aggregate principal amount of such Securities that remains
unpurchased exceeds one-eleventh of the aggregate principal amount of all the
Securities, or if the Company 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 Company or the Guarantors, except that the Company and each of the
Guarantors will continue to be liable for the payment of expenses as set forth
in Section 10 hereof and except that the provisions of Section 7 hereof 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 Company, the Guarantors or any
non-defaulting Initial Purchaser for damages caused by its default.

26

--------------------------------------------------------------------------------

 

     10. Payment of Expenses.
     (a) Whether or not the transactions contemplated by this Agreement are
consummated or this Agreement is terminated, the Company and each of the
Guarantors jointly and severally agree to pay or cause to be paid all costs and
expenses incident to the performance of their respective obligations hereunder,
including without limitation, (i) the costs incident to the authorization,
issuance, sale, preparation and delivery of the Securities and any transfer fees
or taxes payable in that connection; (ii) the costs incident to the preparation,
printing of the Preliminary Offering Memorandum, any other Time of Sale
Information, any Issuer Written Communication and the Offering Memorandum
(including any amendment or supplement thereto) and the distribution thereof;
(iii) the costs of reproducing and distributing each of the Transaction
Documents; (iv) the fees and expenses of the Company’s and the Guarantors’
counsel, the independent accountants and reserve engineers; (v) the fees and
expenses incurred in connection with the registration or qualification and
determination of eligibility for investment of the Securities under the laws of
such jurisdictions as the Representative may designate and the preparation,
printing and distribution of a Blue Sky Memorandum (including the related fees
and expenses of counsel for the Initial Purchasers); (vi) any fees charged by
rating agencies for rating the Securities; (vii) the fees and expenses of the
Trustee and any paying agent (including related fees and expenses of any counsel
to such parties); (viii) all expenses and application fees incurred in
connection with the approval of the Securities for book-entry transfer by DTC;
and (ix) all expenses incurred by the Company in connection with any “road show”
presentation to potential investors (including, without limitation, expenses
associated with the preparation or dissemination of any electronic road show,
expenses associated with the production of road show slides and graphics, fees
and expenses of any consultants engaged in connection with the road show
presentations with the prior approval of the Company, travel and lodging
expenses of the representatives and officers of the Company and any such
consultants; provided that notwithstanding clause (ix) above, the Initial
Purchasers shall pay one-half of the lease expenses associated with any airplane
which is used in connection with such “road show” presentations.
     (b) If (i) this Agreement is terminated pursuant to clauses (ii) or (vi) of
Section 8, (ii) the Company for any reason fails to tender the Securities for
delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to
purchase the Securities for any reason permitted under this Agreement, the
Company and each of the Guarantors jointly and severally agrees to reimburse the
Initial Purchasers for all out-of-pocket costs and expenses (including the fees
and expenses of their counsel) reasonably incurred by the Initial Purchasers in
connection with this Agreement and the offering contemplated hereby.
     11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to
the benefit of and be binding upon the parties hereto and their respective
successors and any controlling persons referred to herein, and the affiliates,
officers and directors of each Initial Purchaser referred to in Section 7
hereof. Nothing 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 provision contained herein. No purchaser of Securities
from any Initial Purchaser shall be deemed to be a successor merely by reason of
such purchase.
     12. Survival. The respective indemnities, rights of contribution,
representations, warranties and agreements of the Company, the Guarantors and
the Initial Purchasers contained

27

--------------------------------------------------------------------------------

 

in this Agreement or made by or on behalf of the Company, the Guarantors or the
Initial Purchasers pursuant to this Agreement or any certificate delivered
pursuant hereto shall survive the delivery of and payment for the Securities and
shall remain in full force and effect, regardless of any termination of this
Agreement or any investigation made by or on behalf of the Company, the
Guarantors or the Initial Purchasers.
     13. Certain Defined Terms. For purposes of this Agreement, (a) except where
otherwise expressly provided, the term “affiliate” has the meaning set forth in
Rule 405 under the Securities Act; (b) the term “business day” means any day
other than a day on which banks are permitted or required to be closed in New

any resale of such Exchange Securities.
     As soon as practicable after the last Exchange Date, the Company and the
Guarantors shall:

  (i)   accept for exchange Registrable Securities or portions thereof validly
tendered and not properly withdrawn pursuant to the Exchange Offer; and     (ii)
  deliver, or cause to be delivered, to the Trustee for cancellation all
Registrable Securities or portions thereof so accepted for exchange by the
Company and issue, and cause the Trustee to promptly authenticate and deliver to
each Holder, Exchange Securities equal in principal amount to the principal
amount of the Registrable Securities tendered by such Holder.

     The Company and the Guarantors shall use commercially reasonable efforts to
complete the Exchange Offer as provided above and shall comply with the
applicable requirements of the Securities Act, the Exchange Act and other
applicable laws and regulations in connection with the Exchange Offer. The
Exchange Offer shall not be subject to any conditions, other than that the
Exchange Offer does not violate any applicable law or applicable interpretations
of the Staff.
          (b) In the event that (i) the Company and the Guarantors determine
that the Exchange Offer Registration provided for in Section 2(a) above is not
available or the Exchange Offer may not be completed as soon as practicable
after the last Exchange Date because it would violate any applicable law or
applicable interpretations of the Staff, (ii) the Exchange Offer is not for any
other reason completed by January 28, 2012 or (iii) any Initial Purchaser shall
so request

Exhibit - A-6

--------------------------------------------------------------------------------

 

in connection with any offer or sale of Registrable Securities (a “Shelf
Request”), the Company and the Guarantors shall use commercially reasonable
efforts to cause to be filed as soon as practicable after such determination,
date or Shelf Request, as the case may be, a Shelf Registration Statement
providing for the sale of all the Registrable Securities by the Holders thereof
and to have such Shelf Registration Statement become effective; provided that no
Holder will be entitled to have any Registrable Securities included in any Shelf
Registration Statement, or entitled to use the prospectus forming a part of such
Shelf Registration Statement, until such Holder shall have delivered a completed
and signed Notice and Questionnaire and provided such other information
regarding such Holder to the Company as is contemplated by Section 3(b) hereof.
     In the event that the Company and the Guarantors are required to file a
Shelf Registration Statement pursuant to clause (iii) of the preceding sentence,
the Company and the Guarantors shall use commercially reasonable efforts to file
and have declared effective by the SEC (or file and become effective
automatically, as the case may be) both an Exchange Offer Registration Statement
pursuant to Section 2(a) above with respect to all Registrable Securities and a
Shelf Registration Statement (which may be a combined Registration Statement
with the Exchange Offer Registration Statement) with respect to offers and sales
of Registrable Securities held by the Initial Purchasers after completion of the
Exchange Offer.
     The Company and the Guarantors agree to use commercially reasonable efforts
to keep the Shelf Registration Statement continuously effective until the
earlier of one year following the effective date of the Shelf Registration
Statement and such time as all the Registrable Securities covered by the Shelf
Registration Statement have been sold pursuant to the Shelf Registration
Statement (the “Shelf Effectiveness Period”). The Company and the Guarantors
further agree to supplement or amend the Shelf Registration Statement, the
related Prospectus and any Free Writing Prospectus if required by the rules,
regulations or instructions applicable to the registration form used by the
Company for such Shelf Registration Statement or by the Securities Act or by any
other rules and regulations thereunder or if reasonably requested by a
Participating Holder with respect to information relating to such Holder, and,
to the extent necessary, to use commercially reasonable efforts to cause any
such amendment to become effective and such Shelf Registration Statement,
Prospectus or Free Writing Prospectus, as the case may be, to become usable as
soon as thereafter practicable. The Company and the Guarantors agree to furnish
to the Participating Holders copies of any such supplement or amendment promptly
after its being used or filed with the SEC.
          (c) The Company and the Guarantors shall pay all Registration Expenses
in connection with any registration pursuant to Section 2(a) or Section 2(b)
hereof. Each Holder shall pay all underwriting discounts and commissions,
brokerage commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder’s Registrable Securities pursuant to the Shelf
Registration Statement.
          (d) An Exchange Offer Registration Statement pursuant to Section 2(a)
hereof will not be deemed to have become effective unless it has been declared
effective by the SEC. A Shelf Registration Statement pursuant to Section 2(b)
hereof will not be deemed to have become effective unless it has been declared
effective by the SEC or is automatically effective upon filing with the SEC as
provided by Rule 462 under the Securities Act.

Exhibit - A-7

--------------------------------------------------------------------------------

 

     In the event that either the Exchange Offer is not completed or the Shelf
Registration Statement, if required hereby, is not declared effective (or does
not automatically become effective) on or prior to January 28, 2012, the Company
will pay liquidated damages to Holders of Registrable Securities with the effect
that the interest rate on the Registrable Securities will be increased by 1.00%
per annum until the Exchange Offer is completed or the Shelf Registration
Statement, if required hereby, is declared effective by the SEC (or becomes
automatically effective). All liquidated damages will be paid by the Company on
the next scheduled interest payment date in the same manner as interest is paid
on the Securities under the Indenture.
     If the Shelf Registration Statement, if required hereby, has been declared
effective or automatically becomes effective, as the case may be, and thereafter
either ceases to be effective or the Prospectus contained therein ceases to be
usable at any time during the Shelf Effectiveness Period, and such failure to
remain effective or usable exists for more than 30 days (whether or not
consecutive) in any 12-month period, unless such failure to remain effective or
usable relates or is directly attributable to an acquisition or disposition
being undertaken by the Company then the Company will pay liquidated damages to
the Holders of Registrable Securities with the effect that the interest rate on
the Registrable Securities will be increased by 1.00% per annum commencing on
the 31st day in such 12-month period and ending on such date that the Shelf
Registration Statement has again been declared (or automatically becomes)
effective or the Prospectus again becomes usable.
          (e) Without limiting the remedies available to the Initial Purchasers
and the Holders, the Company and the Guarantors acknowledge that any failure by
the Company or the Guarantors to comply with their obligations under
Section 2(a) and Section 2(b) hereof may result in material irreparable injury
to the Initial Purchasers or the Holders for which there is no adequate remedy
at law, that it will not be possible to measure damages for such injuries
precisely and that, in the event of any such failure, the Initial Purchasers or
any Holder may obtain such relief as may be required to specifically enforce the
Company’s and the Guarantors’ obligations under Section 2(a) and Section 2(b)
hereof. The provisions for liquidated damages set forth in Section 2(d) above
shall be the only monetary remedy available to the Holders under this Agreement.
     17. Registration Procedures. (a) In connection with their obligations
pursuant to Section 2(a) and Section 2(b) hereof, the Company and the Guarantors
shall as expeditiously as possible:

  (i)   prepare and file with the SEC a Registration Statement on the
appropriate form under the Securities Act, which form (x) shall be selected by
the Company and the Guarantors, (y) shall, in the case of a Shelf Registration,
be available for the sale of the Registrable Securities by the Participating
Holders thereof and (z) shall comply as to form in all material respects with
the requirements of the applicable form and include all financial statements and
oil and gas reserve information required by the SEC to be filed therewith; and
use commercially reasonable efforts to cause such Registration Statement to
become effective and remain effective for the applicable period in accordance
with Section 2 hereof;

Exhibit - A-8

--------------------------------------------------------------------------------

 

  (ii)   prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such
Registration Statement effective for the applicable period in accordance with
Section 2 hereof and cause each Prospectus to be supplemented by any required
prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424
under the Securities Act; and keep each Prospectus current during the period
described in Section 4(3) of and Rule 174 under the Securities Act that is
applicable to transactions by brokers or dealers with respect to the Registrable
Securities or Exchange Securities;     (iii)   to the extent any Free Writing
Prospectus is used, file with the SEC any Free Writing Prospectus that is
required to be filed by the Company or the Guarantors with the SEC in accordance
with the Securities Act and to retain any Free Writing Prospectus not required
to be filed;     (iv)   in the case of a Shelf Registration, furnish to each
Participating Holder, to counsel for the Initial Purchasers, to counsel for such
Participating Holders and to each Underwriter of an Underwritten Offering of
Registrable Securities, if any, without charge, as many copies of each
Prospectus, including each preliminary prospectus or Free Writing Prospectus,
and any amendment or supplement thereto, as such Participating Holder, counsel
or Underwriter may reasonably request in order to facilitate the sale or other
disposition of the Registrable Securities thereunder; and, subject to
Section 3(c) below, the Company and the Guarantors’ consent to the use of such
Prospectus, preliminary prospectus or such Free Writing Prospectus and any
amendment or supplement thereto in accordance with applicable law by each of the
Participating Holders and any such Underwriters in connection with the offering
and sale of the Registrable Securities covered by and in the manner described in
such Prospectus, preliminary prospectus or such Free Writing Prospectus or any
amendment or supplement thereto in accordance with applicable law;     (v)   use
commercially reasonable efforts to register or qualify the Registrable
Securities under all applicable state securities or blue sky laws of such
jurisdictions as any Participating Holder shall reasonably request in writing by
the time the applicable Registration Statement becomes effective; cooperate with
such Participating Holders in connection with any filings required to be made
with FINRA, and do any and all other acts and things that may be reasonably
necessary or advisable to enable each Participating Holder to complete the
disposition in each such jurisdiction of the Registrable Securities owned by
such Participating Holder; provided that neither the Company nor any Guarantor
shall be required to (1) qualify as a foreign corporation or other entity or as
a dealer in securities in any such jurisdiction where it would not otherwise be
required to so qualify, (2) file any general consent to service of process in
any such jurisdiction or (3) subject itself to taxation in any such jurisdiction
if it is not so subject;     (vi)   notify counsel for the Initial Purchasers
and, in the case of a Shelf Registration, notify each Participating Holder and
counsel for such Participating Holders

Exhibit - A-9

--------------------------------------------------------------------------------

 

      promptly and, if requested by any such Participating Holder or counsel,
confirm such advice in writing (1) when a Registration Statement has become
effective, when any post-effective amendment thereto has been filed and becomes
effective, when any Free Writing Prospectus has been filed or any amendment or
supplement to the Prospectus or any Free Writing Prospectus has been filed,
(2) of any request by the SEC or any state securities authority for amendments
and supplements to a Registration Statement, Prospectus or any Free Writing
Prospectus or for additional information after the Registration Statement has
become effective, (3) of the issuance by the SEC or any state securities
authority of any stop order suspending the effectiveness of a Registration
Statement or the initiation of any proceedings for that purpose, including the
receipt by the Company of any notice of objection of the SEC to the use of a
Shelf Registration Statement or any post-effective amendment thereto pursuant to
Rule 401(g)(2) under the Securities Act, (4) if, between the applicable
effective date of a Shelf Registration Statement and the closing of any sale of
Registrable Securities covered thereby, the representations and warranties of
the Company or any Guarantor contained in any underwriting agreement, securities
sales agreement or other similar agreement, if any, relating to an offering of
such Registrable Securities cease to be true and correct in all material
respects or if the Company or any Guarantor receives any notification with
respect to the suspension of the qualification of the Registrable Securities for
sale in any jurisdiction or the initiation of any proceeding for such purpose,
(5) of the happening of any event during the period a Registration Statement is
effective that makes any statement made in such Registration Statement or the
related Prospectus or any Free Writing Prospectus untrue in any material respect
or that requires the making of any changes in such Registration Statement or
Prospectus or any Free Writing Prospectus in order to make the statements
therein, in the light of the circumstances in which they were made in the case
of the Prospectus or any Free Writing Prospectus, not misleading and (6) of any
determination by the Company or any Guarantor that a post-effective amendment to
a Registration Statement or any amendment or supplement to the Prospectus or any
Free Writing Prospectus would be appropriate;     (vii)   use commercially
reasonable efforts to obtain the withdrawal of any order suspending the
effectiveness of a Registration Statement or, in the case of a Shelf
Registration, the resolution of any objection of the SEC pursuant to
Rule 401(g)(2) under the Securities Act, including by filing an amendment to
such Registration Statement on the proper form, at the earliest practicable
moment and provide immediate notice to each Holder or Participating Holder of
the withdrawal of any such order or such resolution;     (viii)   in the case of
a Shelf Registration, furnish or make available to each Participating Holder,
without charge, at least one conformed copy of each Registration Statement and
any post-effective amendment thereto (without any documents incorporated therein
by reference or exhibits thereto, unless requested);

Exhibit - A-10

--------------------------------------------------------------------------------

 

  (ix)   in the case of a Shelf Registration, cooperate with the Participating
Holders to facilitate the timely preparation and delivery of certificates
representing Registrable Securities to be sold and not bearing any restrictive
legends and enable such Registrable Securities to be issued in such
denominations and registered in such names (consistent with the provisions of
the Indenture) as such Participating Holders may reasonably request at least one
Business Day prior to the closing of any sale of Registrable Securities;     (x)
  upon the occurrence of any event contemplated by Section 3(a)(vi)(5) hereof,
use commercially reasonable efforts to prepare and file with the SEC a
supplement or post-effective amendment to the Exchange Offer Registration
Statement or Shelf Registration Statement or the related Prospectus or any Free
Writing Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered (or, to the extent
permitted by law, made available) to purchasers of the Registrable Securities,
such Prospectus or Free Writing Prospectus, as the case may be, will not contain
any untrue statement of a material fact or 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 the Company and the Guarantors
shall notify the Participating Holders (in the case of a Shelf Registration
Statement) and the Initial Purchasers and any Participating Broker-Dealers known
to the Company (in the case of the Exchange Offer Registration Statement) to
suspend use of the Prospectus or any Free Writing Prospectus as promptly as
practicable after the occurrence of such an event, and such Participating
Holders, such Participating Broker-Dealers and the Initial Purchasers, as
applicable, hereby agree to suspend use of the Prospectus or any Free Writing
Prospectus, as the case may be, until the Company and the Guarantors have
amended or supplemented the Prospectus or the Free Writing Prospectus, as the
case may be, to correct such misstatement or omission; provided that the
obligations under this Section 3(a)(x) with respect to the Exchange Offer
Registration Statement shall terminate at the end of the period set forth in
Section 2(a)(ii) of this Agreement;     (xi)   a reasonable time prior to the
filing of any Registration Statement, any Prospectus, any Free Writing
Prospectus, any amendment to a Registration Statement or amendment or supplement
to a Prospectus or a Free Writing Prospectus, provide copies of such document to
the Initial Purchasers and their counsel (and, in the case of a Shelf
Registration Statement, to the Participating Holders and their counsel) and make
such of the representatives of the Company and the Guarantors as shall be
reasonably requested by the Initial Purchasers or their counsel (and, in the
case of a Shelf Registration Statement, the Participating Holders or their
counsel) available for discussion of such document; and the Company and the
Guarantors shall not, at any time after initial filing of a Registration
Statement, use or file any Prospectus, any Free Writing Prospectus, any
amendment of or supplement to a Registration Statement, a Prospectus or a Free
Writing Prospectus, of which the Initial Purchasers and their counsel (and, in
the case of a Shelf Registration Statement, the Participating Holders and their
counsel) shall not have previously been advised and furnished a copy or to which

Exhibit - A-11

--------------------------------------------------------------------------------

 

      the Initial Purchasers or their counsel (and, in the case of a Shelf
Registration Statement, the Participating Holders or their counsel) shall
reasonably object;     (xii)   obtain a CUSIP number for all Exchange Securities
or Registrable Securities, as the case may be, not later than the initial
effective date of a Registration Statement;     (xiii)   cause the Indenture to
be qualified under the Trust Indenture Act in connection with the registration
of the Exchange Securities or Registrable Securities, as the case may be;
cooperate with the Trustee and the Holders to effect such changes to the
Indenture as may be required for the Indenture to be so qualified in accordance
with the terms of the Trust Indenture Act; and execute, and use commercially
reasonable efforts to cause the Trustee to execute, all documents as may be
required to effect such changes and all other forms and documents required to be
filed with the SEC to enable the Indenture to be so qualified in a timely
manner;     (xiv)   in the case of a Shelf Registration, make available for
inspection by a representative of the Participating Holders (an “Inspector”),
any Underwriter participating in any disposition pursuant to such Shelf
Registration Statement, any attorneys and accountants designated by a majority
in aggregate principal amount of the Registrable Securities held by the
Participating Holders and any attorneys and accountants designated by such
Underwriter, at reasonable times and in a reasonable manner, all pertinent
financial and other records, documents and properties of the Company and its
subsidiaries, and cause the respective officers, directors and employees of the
Company and the Guarantors to supply all information reasonably requested by any
such Inspector, Underwriter, attorney or accountant in connection with a Shelf
Registration Statement; provided that if any such information is identified by
the Company or any Guarantor as being confidential or proprietary, each Person
receiving such information shall take such actions as are reasonably necessary
to protect the confidentiality of such information to the extent such action is
otherwise not inconsistent with, an impairment of or in derogation of the rights
and interests of any Inspector, Participating Holder or Underwriter;     (xv)  
if reasonably requested by any Participating Holder, promptly include in a
Prospectus supplement or post-effective amendment such information with respect
to such Participating Holder as such Participating Holder reasonably requests to
be included therein and make all required filings of such Prospectus supplement
or such post-effective amendment as soon as the Company has received
notification of the matters to be so included in such filing;     (xvi)   in the
case of a Shelf Registration, enter into such customary agreements and take all
such other commercially reasonable actions in connection therewith (including
those requested by the Participating Holders of a majority in principal amount
of the Registrable Securities covered by the Shelf Registration Statement) in
order to expedite or facilitate the disposition of such Registrable Securities
including, but

Exhibit - A-12

--------------------------------------------------------------------------------

 

      not limited to, an Underwritten Offering and in such connection, (1) to
the extent possible, make such representations and warranties to the
Participating Holders and any Underwriters of such Registrable Securities with
respect to the business of the Company and its subsidiaries and the Registration
Statement, Prospectus, any Free Writing Prospectus and documents incorporated by
reference or deemed incorporated by reference, if any, in each case, in form,
substance and scope as are customarily made by issuers to underwriters in
underwritten offerings and confirm the same if and when requested, (2) obtain
opinions of counsel to the Company and the Guarantors (which counsel and
opinions, in form, scope and substance, shall be reasonably satisfactory to the
Participating Holders and such Underwriters and their respective counsel)
addressed to each Participating Holder and Underwriter of Registrable
Securities, covering the matters customarily covered in opinions requested in
underwritten offerings, (3) obtain “comfort” letters from the independent
certified public accountants of the Company and the Guarantors (and, if
necessary, any other certified public accountant of any subsidiary of the
Company or the Guarantors, or of any business acquired by the Company or the
Guarantors for which financial statements and financial data are or are required
to be included in the Registration Statement) addressed to each Participating
Holder (to the extent permitted by applicable professional standards) and
Underwriter of Registrable Securities, such letters to be in customary form and
covering matters of the type customarily covered in “comfort” letters in
connection with underwritten offerings, including but not limited to financial
information contained in any preliminary prospectus, Prospectus or Free Writing
Prospectus, (4) obtain oil and gas reserve report letters from any independent
petroleum engineering firms whose reports relating to the Company’s reserves
have, prior to the date of such Shelf Registration, been previously publicly
disclosed in a filing by the Company and (5) deliver such documents and
certificates as may be reasonably requested by the Participating Holders of a
majority in principal amount of the Registrable Securities being sold or the
Underwriters, and which are customarily delivered in underwritten offerings, to
evidence the continued validity of the representations and warranties of the
Company and the Guarantors made pursuant to clause (1) above and to evidence
compliance with any customary conditions contained in an underwriting agreement;
and     (xvii)   So long as any Registrable Securities remain outstanding, cause
each Additional Guarantor upon the creation or acquisition by the Company of
such Additional Guarantor, to execute a counterpart to this Agreement in the
form attached hereto as Annex A and to deliver such counterpart, together with
an opinion of counsel as to the enforceability thereof against such entity, to
the Initial Purchasers no later than five Business Days following the execution
thereof.

          (b) In the case of a Shelf Registration Statement, the Company may
require each Holder of Registrable Securities to furnish to the Company a Notice
and Questionnaire and such other information regarding such Holder and the
proposed disposition by such Holder of such Registrable Securities as the
Company and the Guarantors may from time to time reasonably request in writing.

Exhibit - A-13

--------------------------------------------------------------------------------

 

          (c) Each Participating Holder agrees that, upon receipt of any notice
from the Company and the Guarantors of the happening of any event of the kind
described in Section 3(a)(vi)(3) or Section 3(a)(vi)(5) hereof, such
Participating Holder will forthwith discontinue disposition of Registrable
Securities pursuant to the Shelf Registration Statement until such Participating
Holder’s receipt of the copies of the supplemented or amended Prospectus and any
Free Writing Prospectus contemplated by Section 3(a)(x) hereof and, if so
directed by the Company and the Guarantors, such Participating Holder will
deliver to the Company and the Guarantors all copies in its possession, other
than permanent file copies then in such Participating Holder’s possession, of
the Prospectus and any Free Writing Prospectus covering such Registrable
Securities that is current at the time of receipt of such notice.
          (d) If the Company and the Guarantors shall give any notice to suspend
the disposition of Registrable Securities pursuant to a Registration Statement,
the Company and the Guarantors shall extend the period during which such
Registration Statement shall be maintained effective pursuant to this Agreement
by the number of days during the period from and including the date of the
giving of such notice to and including the date when the Holders of such
Registrable Securities shall have received copies of the supplemented or amended
Prospectus or any Free Writing Prospectus necessary to resume such dispositions.
The Company and the Guarantors may give any such notice only twice during any
365-day period and any such suspensions shall not exceed 30 days for each
suspension and there shall not be more than two suspensions in effect during any
365-day period.
          (e) The Participating Holders who desire to do so may sell such
Registrable Securities in an Underwritten Offering. In any such Underwritten
Offering, the investment bank or investment banks and manager or managers (each
an “Underwriter”) that will administer the offering will be selected by the
Holders of a majority in principal amount of the Registrable Securities included
in such offering; provided, however, that such Underwriter must be reasonably
satisfactory to the Company.
     18. Participation of Broker-Dealers in Exchange Offer. (a) The Staff has
taken the position that any broker-dealer that receives Exchange Securities for
its own account in the Exchange Offer in exchange for Securities that were
acquired by such broker-dealer as a result of market-making or other trading
activities (a “Participating Broker-Dealer”) may be deemed to be an
“underwriter” within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Securities.
     The Company and the Guarantors understand that it is the Staff’s position
that if the Prospectus contained in the Exchange Offer Registration Statement
includes a plan of distribution containing a statement to the above effect and
the means by which Participating Broker-Dealers may resell the Exchange
Securities, without naming the Participating Broker-Dealers or specifying the
amount of Exchange Securities owned by them, such Prospectus may be delivered by
Participating Broker-Dealers (or, to the extent permitted by law, made available
to purchasers) to satisfy their prospectus delivery obligation under the
Securities Act in connection with resales of Exchange Securities for their own
accounts, so long as the Prospectus otherwise meets the requirements of the
Securities Act.

Exhibit - A-14

--------------------------------------------------------------------------------

 

          (b) In light of the above, and notwithstanding the other provisions of
this Agreement, the Company and the Guarantors agree to amend or supplement the
Prospectus contained in the Exchange Offer Registration Statement for a period
of up to 180 days after the last Exchange Date (as such period may be extended
pursuant to Section 3(d) of this Agreement), in order to expedite or facilitate
the disposition of any Exchange Securities by Participating Broker-Dealers
consistent with the positions of the Staff recited in Section 4(a) above. The
Company and the Guarantors further agree that Participating Broker-Dealers shall
be authorized to deliver such Prospectus (or, to the extent permitted by law,
make available) during such period in connection with the resales contemplated
by this Section 4.
          (c) The Initial Purchasers shall have no liability to the Company, any
Guarantor or any Holder with respect to any request that they may make pursuant
to Section 4(b) above.
     19. Indemnification and Contribution. (a) The Company and the Guarantors,
jointly and severally, agree to indemnify and hold harmless each Initial
Purchaser and each Holder, their respective affiliates, directors and officers
and each Person, if any, who controls any Initial Purchaser or any Holder within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act, from and against any and all losses, claims, damages and liabilities
(including, without limitation, legal fees and other expenses incurred in
connection with any suit, action or proceeding or any claim asserted, as such
fees and expenses are incurred), joint or several, that arise out of, or are
based upon, (1) any untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement or any omission or alleged omission
to state therein a material fact required to be stated therein or necessary in
order to make the statements therein not misleading, or (2) any untrue statement
or alleged untrue statement of a material fact contained in any Prospectus, any
Free Writing Prospectus or any “issuer information” (“Issuer Information”) filed
or required to be filed pursuant to Rule 433(d) under the Securities Act, or any
omission or alleged omission to state therein a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, in each case except insofar as such losses,
claims, damages or liabilities arise out of, or are based upon, any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with any information relating to any Initial Purchaser or
information relating to any Holder furnished to the Company in writing through
J.P. Morgan or any selling Holder expressly for use therein. In connection with
any Underwritten Offering permitted by Section 3, the Company and the
Guarantors, jointly and severally, will also indemnify the Underwriters, if any,
selling brokers, dealers and similar securities industry professionals
participating in the distribution, their respective affiliates and each Person
who controls such Persons (within the meaning of the Securities Act and the
Exchange Act) to the same extent as provided above with respect to the
indemnification of the Holders, if requested in connection with any Registration
Statement, any Prospectus, any Free Writing Prospectus or any Issuer
Information.
          (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Guarantors, the Initial Purchasers and the other
selling Holders, the directors of the Company and the Guarantors, each officer
of the Company and the Guarantors who signed the Registration Statement and each
Person, if any, who controls the Company, the Guarantors, any Initial Purchaser
and any other selling Holder within the meaning of Section 15

Exhibit - A-15

--------------------------------------------------------------------------------

 

of the Securities Act or Section 20 of the Exchange Act to the same extent as
the indemnity set forth in paragraph (a) above, but only with respect to any
losses, claims, damages or liabilities that arise out of, or are based upon, any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with any information relating to such Holder
furnished to the Company in writing by such Holder expressly for use in any
Registration Statement, any Prospectus and any Free Writing Prospectus.
          (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnification may be sought pursuant to either
paragraph (a) or (b) above, such Person (the “Indemnified Person”) shall
promptly notify the Person against whom such indemnification may be sought (the
“Indemnifying Person”) in writing; provided that the failure to notify the
Indemnifying Person shall not relieve it from any liability that it may have
under paragraph (a) or (b) above except to the extent that 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 Person shall not relieve it from any liability that it may have to
an Indemnified Person otherwise than under paragraph (a) or (b) above. If any
such proceeding shall be brought or asserted against an Indemnified Person and
it shall have notified the Indemnifying Person thereof, the Indemnifying Person
shall retain counsel reasonably satisfactory to the Indemnified Person to
represent the Indemnified Person and any others entitled to indemnification
pursuant to this Section 5 that the Indemnifying Person may designate in such
proceeding and shall pay the fees and expenses of such counsel related to such
proceeding, as incurred. In any such proceeding, any Indemnified Person shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed to the
contrary; (ii) the Indemnifying Person has failed within a reasonable time to
retain counsel reasonably satisfactory to the Indemnified Person; (iii) the
Indemnified Person shall have reasonably concluded that there may be legal
defenses available to it that are different from or in addition to those
available to the Indemnifying Person; or (iv) the named parties in any such
proceeding (including any impleaded parties) include both the Indemnifying
Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. It is understood and agreed that the Indemnifying Person shall
not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm (x) for any Initial Purchaser, its affiliates, directors and
officers and any control Persons of such Initial Purchaser shall be designated
in writing by J.P. Morgan, (y) for any Holder, its directors and officers and
any control Persons of such Holder shall be designated in writing by the
Majority Holders and (z) in all other cases shall be designated in writing by
the Company. The Indemnifying Person shall not be liable for any settlement of
any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Indemnifying
Person agrees to indemnify each Indemnified Person from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested
that an Indemnifying Person reimburse the Indemnified Person for fees and
expenses of counsel as contemplated by this paragraph, the Indemnifying Person
shall be liable for any settlement of any proceeding effected without its
written consent if

Exhibit - A-16

--------------------------------------------------------------------------------

 

(i) such settlement is entered into more than 30 days after receipt by the
Indemnifying Person of such request and (ii) the Indemnifying Person shall not
have reimbursed the Indemnified Person in accordance with such request prior to
the date of such settlement. No Indemnifying Person shall, without the written
consent of the Indemnified Person, effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could
have been a party and indemnification could have been sought hereunder by such
Indemnified Person, unless such settlement (A) includes an unconditional release
of such Indemnified Person, in form and substance reasonably satisfactory to
such Indemnified Person, from all liability on claims that are the subject
matter of such proceeding and (B) does not include any statement as to or any
admission of fault, culpability or a failure to act by or on behalf of any
Indemnified Person.
          (d) If the indemnification provided for in paragraphs (a) and (b)
above is unavailable to an Indemnified Person or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Guarantors from the offering of the
Securities and the Exchange Securities, on the one hand, and by the Holders from
receiving Securities or Exchange Securities registered under the Securities Act,
on the other hand, or (ii) if the allocation provided by clause (i) is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) but also the relative fault
of the Company and the Guarantors on the one hand and the Holders on the other
in connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Guarantors on the one
hand and the Holders on the other 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 Company and the Guarantors or by the Holders and the
parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.
          (e) The Company, the Guarantors and the Holders agree that it would
not be just and equitable if contribution pursuant to this Section 5 were
determined by pro rata allocation (even if the Holders were treated as one
entity for such purpose) or by any other method of allocation that does not take
account of the equitable considerations referred to in paragraph (d) above. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in paragraph (d) above shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses incurred by such Indemnified Person in connection with any such
action or claim. Notwithstanding the provisions of this Section 5, in no event
shall a Holder be required to contribute any amount in excess of the amount by
which the total price at which the Securities or Exchange Securities sold by
such Holder exceeds the amount of any damages that such Holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The Holders’ obligations to contribute pursuant to this
Section 5 are several and not joint.

Exhibit - A-17

--------------------------------------------------------------------------------

 

          (f) The remedies provided for in this Section 5 are not exclusive and
shall not limit any rights or remedies that may otherwise be available to any
Indemnified Person at law or in equity.
          (g) The indemnity and contribution provisions contained in this
Section 5 shall remain operative and in full force and effect regardless of
(i) any termination of this Agreement, (ii) any investigation made by or on
behalf of the Initial Purchasers or any Holder or any Person controlling any
Initial Purchaser or any Holder, or by or on behalf of the Company or the
Guarantors or the officers or directors of or any Person controlling the Company
or the Guarantors, (iii) acceptance of any of the Exchange Securities and
(iv) any sale of Registrable Securities pursuant to a Shelf Registration
Statement.
     20. General.
          (a) No Inconsistent Agreements. The Company and the Guarantors
represent, warrant and agree that (i) the rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of any other outstanding securities issued or
guaranteed by the Company or any Guarantor under any other agreement and
(ii) neither the Company nor any Guarantor has entered into, or on or after the
date of this Agreement will enter into, any agreement that is inconsistent with
the rights granted to the Holders of Registrable Securities in this Agreement or
otherwise conflicts with the provisions hereof.
          (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company and the Guarantors have obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or consent; provided that no amendment, modification,
supplement, waiver or consent to any departure from the provisions of Section 5
hereof or any provision that could affect adversely the rights of any Holder of
Registrable Securities to receive liquidated damages in the amount and on the
payment dates as provided in Section 2(d) shall be effective as against any
Holder of Registrable Securities unless consented to in writing by such Holder.
Any amendments, modifications, supplements, waivers or consents pursuant to this
Section 6(b) shall be by a writing executed by each of the parties hereto.
          (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to the Initial
Purchasers, the address set forth in the Purchase Agreement; (ii) if to the
Company and the Guarantors, initially at the Company’s address set forth in the
Purchase Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 6(c); and (iii) to such
other persons at their respective addresses as provided in the Purchase
Agreement and thereafter at such other address, notice of which is given in
accordance with the provisions of this Section 6(c). All such notices and
communications shall be deemed to have been duly

Exhibit - A-18

--------------------------------------------------------------------------------

 

given: at the time delivered by hand, if personally delivered; five Business
Days after being deposited in the mail, postage prepaid, if mailed; when receipt
is acknowledged, if telecopied; and on the next Business Day if timely delivered
to an air courier guaranteeing overnight delivery. Copies of all such notices,
demands or other communications shall be concurrently delivered by the Person
giving the same to the Trustee, at the address specified in the Indenture.
          (d) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Registrable Securities in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all the terms of this Agreement, and by taking and holding such
Registrable Securities such Person shall be conclusively deemed to have agreed
to be bound by and to perform all of the terms and provisions of this Agreement
and such Person shall be entitled to receive the benefits hereof. The Initial
Purchasers (in their capacity as Initial Purchasers) shall have no liability or
obligation to the Company or the Guarantors with respect to any failure by a
Holder to comply with, or any breach by any Holder of, any of the obligations of
such Holder under this Agreement.
          (e) Third Party Beneficiaries. Each Holder shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights or the rights of
other Holders hereunder.
          (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.
          (g) Headings. The headings in this Agreement are for convenience of
reference only, are not a part of this Agreement and shall not limit or
otherwise affect the meaning hereof.
          (h) Governing Law. This Agreement, and any claim, controversy or
dispute arising under or related to this Agreement, shall be governed by and
construed in accordance with the laws of the State of New York.
          (i) Entire Agreement; Severability. This Agreement contains the entire
agreement between the parties relating to the subject matter hereof and
supersedes all oral statements and prior writings with respect thereto. If any
term, provision, covenant or restriction contained in this Agreement is held by
a court of competent jurisdiction to be invalid, void or unenforceable or
against public policy, the remainder of the terms, provisions, covenants and
restrictions contained herein shall remain in full force and effect and shall in
no way be affected, impaired or invalidated. The Company, the Guarantors and the
Initial Purchasers shall endeavor in good faith negotiations to replace the
invalid, void or unenforceable provisions with valid

provisions the economic effect of which comes as close as possible to that of
the invalid, void or unenforceable provisions.

laws of the State of Delaware to (i) execute and deliver, and incur and perform
all of its obligations under, the Purchase Agreement, the Registration Rights
Agreement, the Base Indenture, the Supplemental Indenture and the Securities
(collectively the “Transaction Documents”) and (ii) carry on its business and
own its properties as described in the Time of Sale Information and the Offering

respective obligations under, each of the Transaction Documents to which it is a
party, each in accordance with its terms, (A) constituted, constitutes or will
constitute a violation under any provision of the Delaware Limited Liability

except for any contravention described in clauses (A) or (C) which would not,
individually or in the aggregate, have a Material Adverse Effect.
     5. No consent, approval, authorization or order of, or qualification or
filing with, any governmental body or agency is required for the execution and

approval, authorization, order or qualification would not reasonably be expected
to have a Material Adverse Effect or materially impair the ability of the
Company and Guarantors to consummate the transactions contemplated by the
Transaction Documents.
     6. The statements under the caption “Description of notes” in the
Preliminary Offering Memorandum as supplemented by the Pricing Term Sheet and in
the Offering Memorandum, insofar as such statements purport to summarize certain
provisions of documents referred to therein and reviewed by us as described
above, fairly summarize such provisions in all material respects, subject to the
qualifications and assumptions stated therein.
     7. The statements in the Preliminary Offering Memorandum and the Offering
Memorandum under the caption “Certain United States federal income tax
considerations,” insofar as they refer to statements of law or legal
conclusions, fairly summarize the matters referred to therein in all material
respects, subject to the qualifications and assumptions stated therein.
     8. The Indenture constitutes a valid and binding obligation of each of the
Obligors, enforceable against each of them in accordance with its terms, under
the laws of the State of New York, except as such enforceability may be limited
by the Enforceability Exceptions; and the Indenture conforms in all material
respects with the requirements of the Trust Indenture Act and the rules and
regulations of the Commission applicable to an indenture that is qualified
thereunder.
     9. When authenticated by the Trustee in the manner provided in the
Indenture and delivered to and paid for by the Initial Purchasers in accordance
with the Purchase Agreement, the Securities will constitute valid and binding
obligations of the Company, entitled to the benefits of the Indenture and
enforceable against the Company in accordance with their terms, under the laws
of the State of New York, except as such enforceability may be limited by the
Enforceability Exceptions.
     10. When the Securities have been authenticated by the Trustee in the
manner provided in the Indenture and delivered to and paid for by the Initial
Purchasers in accordance with the Purchase Agreement, the guarantee of the
Securities included in the Indenture will constitute a valid and binding
obligation of the Guarantors, enforceable against the Guarantors in accordance
with the terms of the Indenture, under the laws of the State of New York, except
as such enforceability may be limited by the Enforceability Exceptions.

Exhibit B-2

--------------------------------------------------------------------------------

 

     11. When validly executed by the Company and authenticated by the Trustee
in the manner provided in the Indenture and delivered in exchange for Initial
Securities pursuant to the Exchange Offer contemplated by the Registration
Rights Agreement, the Exchange Securities will constitute valid and binding
obligations of the Company, entitled to the benefits of the Indenture and
enforceable against the Company in accordance with their terms, under the laws
of the State of New York, except as such enforceability may be limited by the
Enforceability Exceptions.
     12. When the Exchange Securities have been validly executed by the Company
and authenticated by the Trustee in accordance with the provisions of the
Indenture and delivered in exchange for Initial Securities pursuant to the
Exchange Offer contemplated by the Registration Rights Agreement, the guarantee
included in the Indenture of the Exchange Securities will constitute a valid and
binding obligation of the Guarantors, enforceable against the Guarantors in
accordance with the terms of the Indenture, under the laws of the State of New
York, except as such enforceability may be limited by the Enforceability
Exceptions.
     13. The Registration Rights Agreement constitutes a valid and binding
obligation of each of the Obligors, enforceable against each of them in
accordance with its terms, under the laws of the State of New York, except as
such enforceability may be limited by the Enforceability Exceptions.
     14. (A) Assuming the accuracy of the representations, warranties and
covenants of the Company, Guarantors and Initial Purchasers set forth in ( ), (
), ( ) in the Purchase Agreement, the offer, issue, sale and delivery of the
Securities (and the guaranties thereof by the Guarantors) to the Initial
Purchasers and the initial resale of the Securities (and the guaranties thereof
by the Guarantors) by the Initial Purchasers, each in the manner contemplated by
the Purchase Agreement and the Offering Memorandum, do not require registration
under the Securities Act, and (B) prior to the consummation of the Exchange
Offer or the effectiveness of the Shelf Registration Statement (as defined in
the Registration Rights Agreement), such offer, issue, sale and delivery of the
Securities (and the guaranties thereof by the Guarantors) and such initial
resale of the Securities (and the guaranties thereof by the Guarantors) do not
require qualification of the Indenture under the Trust Indenture Act, as
amended, provided, however, that we express no opinion as to any subsequent
resale of any Security (and the guaranties thereof by the Guarantors) or any
Exchange Security (and the guaranties thereof by the Guarantors).
     15. The Company and the Guarantors are not, and immediately after giving
effect to the issuance and sale of the Securities pursuant to the Purchase
Agreement and the application of proceeds therefrom as described in the
Preliminary Offering Memorandum as supplemented by the Pricing Term Sheet and in
the Offering Memorandum, will not be, an “investment company” within the meaning
of said term as used in the Investment Company Act of 1940, as amended.
     16. In a case properly argued and presented, a Texas court or a United
States federal court sitting in Texas and applying Texas conflict of law
principles as set out in Chapter 271 of the Texas Business and Commerce Code,
would give effect to the provisions of the Securities and the provisions of the
Indenture that purport to require that the rights and obligations of the parties
thereto are to be governed by and construed in accordance with the laws of the
State of New York.

Exhibit B-3

--------------------------------------------------------------------------------

 

          In addition, we have participated in conferences with officers and
other representatives of the Obligors, the independent registered public
accounting firm and the reserve engineer for the Obligors, your counsel and your
representatives at which the contents of the Time of Sale Information and the
Offering Memorandum and related matters were discussed and, although we have not
independently verified and are not passing upon, and do not assume any
responsibility for, the accuracy, completeness or fairness of the statements
contained in the Time of Sale Information and the Offering Memorandum (except as
and to the extent set forth in paragraphs 6 and 7 above), on the basis of the
foregoing (relying as to factual matters to the extent we deem reasonable upon
statements of fact made to us by representatives of the Obligors), no facts have
come to our attention that have led us to believe that (i) the Time of Sale
Information, as of 12:15 p.m. (Eastern Standard Time) on January 28, 2011
contained an untrue statement of a material fact or omitted 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) the Offering
Memorandum, as of its date and as of the date hereof, contained or contains an
untrue statement of a material fact or omitted or omits to state any material
fact necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading, it being understood that we express
no statement or belief with respect to (i) the historical financial statements
and related schedules, including the notes and schedules thereto and the
auditor’s report thereon (and any other financial or accounting data derived
therefrom) and (ii) oil and natural gas reserve estimates, in each case included
in, or excluded from, the Offering Memorandum or the Time of Sale Information.
