        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for exchange Registrable Securities or portions thereof validly tendered and not properly withdrawn pursuant to the Exchange Offer; and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 their 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
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 November 12, 2010 or (iii) upon receipt of a written request (a "Shelf Request") from any Initial Purchaser representing that it holds Registrable
Securities that are or were ineligible to be exchanged in the Exchange Offer (which Shelf Request must be made to the Company and the Guarantors on or before the 270th day
following the date of this Agreement), the Company and the Guarantors shall use their 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. 


        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 their commercially reasonable efforts to file and have become effective both an Exchange Offer Registration Statement pursuant to Section 2(a) 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. 


        In
the event that the Company and the Guarantors are required to file a Shelf Registration Statement pursuant to this Section 2(b), the Company and the Guarantors agree to
use their commercially reasonable efforts to keep the Shelf Registration Statement continuously effective until the earlier of (i) one year following the effective date of such Shelf
Registration Statement or (ii) such shorter period that will terminate when 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 Holder of Registrable Securities with respect to information relating to such Holder, and to use their commercially
reasonable efforts to cause any such amendment to become effective, if required, 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 Holders of Registrable Securities copies of any such supplement or amendment promptly after its being used or
filed with the SEC. 


5







 

        (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. 



        In
the event that either the Exchange Offer is not completed or the Shelf Registration Statement, if required pursuant to Section 2(b)(i), 2(b)(ii) or 2(b)(iii) hereof, does not
become effective on or prior to November 12, 2010 (the "Target Registration Date"), 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, becomes effective. 


        If
the Shelf Registration Statement, if required hereby, has become effective and thereafter either ceases to be effective or the Prospectus contained therein ceases to be usable, in
each case whether or not permitted by this Agreement, 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, then 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 become effective or the Prospectus again becomes usable. 


        (e)   The
provisions for the payment of additional interest set forth in Section 2(d) shall be the only monetary remedy available to Holders for the Company's and the
Guarantors' failure to cause the Exchange Offer Registration Statement or the Shelf Registration Statement to become effective, or continue to be effective, as the case may be, in accordance with the
provisions of this Agreement. 


        3.    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:

Company and the Guarantors, (y) shall, in the case of a Shelf Registration, be available for the resale of the Registrable Securities by the Holders thereof and (z) shall comply as to

to cause such Registration Statement to become effective and remain effective for the applicable period in accordance with Section 2 hereof; 


        (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 Holder of Registrable Securities, to counsel for the Initial Purchasers, to counsel for such Holders and to each
Underwriter of an Underwritten

Securities 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
their commercially reasonable efforts to register or qualify the Registrable Securities under all applicable state securities or blue sky laws of such jurisdictions
as any Holder of Registrable Securities covered by a Registration Statement shall reasonably request in writing by the time the applicable Registration Statement becomes effective; cooperate with such
Holders in connection with any filings required to be made with Financial Industry Regulatory Authority; and do any and all other acts and things that may be reasonably necessary or advisable to
enable each Holder to complete the disposition in each such jurisdiction of the Registrable Securities owned by such 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 Holder of Registrable Securities and counsel for such Holders promptly
and, if requested by any such 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

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 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
their commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a Registration Statement or, in the case of a Shelf

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

        (x)   in
the case of a Shelf Registration, upon the occurrence of any event contemplated by Section 3(a)(vi)(5) hereof, use their commercially reasonable efforts to
prepare and file with the SEC a supplement or post-effective amendment to such 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 Holders of Registrable Securities to suspend use of the Prospectus or any
Free Writing Prospectus as promptly as practicable after the occurrence of such an event, and such Holders hereby agree to suspend use of the Prospectus or any Free Writing Prospectus, as the case may

initial filing of a Registration Statement, provide copies of such document to the Initial Purchasers and their counsel (and, in the case of a Shelf Registration Statement, to the Holders of
Registrable Securities 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 Holders of Registrable Securities 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 or a Prospectus or a Free Writing
Prospectus, or any document that is to be incorporated by reference into 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 Holders of Registrable Securities and their counsel) shall not have previously been advised and furnished a copy or to which the Initial Purchasers or
their counsel (and, in the case of a Shelf Registration Statement, the Holders of Registrable Securities or their counsel) shall object;

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, Holder or Underwriter; 



        (xv) in
the case of a Shelf Registration, use their commercially reasonable efforts to cause all Registrable Securities to be listed on any securities exchange or any
automated quotation system on which similar securities issued or guaranteed by the Company or any Guarantor are then listed if requested by the Majority Holders, to the extent such Registrable
Securities satisfy applicable listing requirements; 


        (xvi) if
reasonably requested by any Holder of Registrable Securities covered by a Shelf Registration Statement, promptly include in a Prospectus supplement or
post-effective amendment such information with respect to such Holder as such 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; 


        (xvii)  in
the case of an Underwritten Offering pursuant to a Shelf Registration Statement, enter into such customary agreements and take all such other actions in connection
therewith (including those requested by the 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 and in such connection, (1) to the extent possible, make such representations and warranties to the 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 such Underwriters and their
counsel) addressed to each 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 any Guarantor, or of any
business acquired by the Company or any Guarantor for which financial statements and financial data are or are required to be included in the Registration Statement) addressed to each selling 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) reserve report confirmation letters from the independent reserve engineers of the Company and the Guarantors in the customary form and covering matters of the type customarily included in
such letters to underwriters in connection with primary underwritten offerings 


9







 



and
(5) deliver such documents and certificates as may be reasonably requested by the 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 



        (xviii)  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 such 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. 


        (c)   In
the case of a Shelf Registration Statement, each Holder of Registrable Securities covered in such Shelf Registration Statement 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 3(a)(vi)(5) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to the Shelf Registration Statement until such 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 Holder will deliver to the Company and the Guarantors all copies in its possession, other than permanent file
copies then in such 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
Holders of Registrable Securities covered by a Shelf Registration Statement 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. 


        4.    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 


10







 



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. 


        (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. 


        5.    Indemnification and Contribution.    (a) The Company and each Guarantor, 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 JPMorgan or any selling Holder, respectively, 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, their affiliates and each Person who controls such Underwriters (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 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 


11







 



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 this Section 5 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 this Section 5. 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 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 JPMorgan, (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. 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 


12







 



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. 


        (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. 


        6.    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 


13







 



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 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 given: at the time
delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; 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 shall be governed by and construed in accordance with the laws of the State of
New York. 


14







 

        (j)    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. 


15







 

        IN
WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
