CGGS owns producing oil and gas properties in western Canada (the "CGGS Properties") and interests ranging from 10% to 100% in 197 miles of natural gas gathering systems and 11 natural gas processing plants or compression facilities, four of which are operated by CGGS (the "CGGS Plants"). The purchase price for the stock was $94.7 million which included approximately $11.0 million for CGGS' working capital. Funding for the acquisition was provided by proceeds from Abraxas' and Canadian Abraxas' recent senior note offering. (See item 5). The CGGS Properties consist of 154,968 gross acres (86,327 net acres) and 120 gross wells (68.8 net wells), 48 of which will be operated by the Company. As of September 1, 1996, the CGGS Properties had total proved reserves of 10,821 MBOE (91.8% natural gas) with aggregate PV-10 of $46.4 million, 86.3% of which is attributable to proved developed reserves. The CGGS Plants had aggregate net natural gas processing capacity of 98.3 MMcf per day at September 1, 1996. (B) On November 14, 1996 Abraxas acquired a 75% partnership interest in Portilla - 1996 L.P. (the "Partnership") for $27.5 million including the repayment of certain indebtedness. The Company previously owned the other 25% interest in the Partnership. The Partnership owned a 100% working interest in the Portilla Field, a 100% interest in a natural gas processing plant located at the Portilla Field, located in the Texas gulf coast region and a 12% working interest in the Happy Field, located in the Permian Basin of west Texas. Funding for the acquisition was provided by proceeds from Abraxas' and Canadian Abraxas' recent senior note offering. (See item 5). Portilla and Happy consist of 1,405 gross acres (1,115 net acres) and 78 gross wells (52 net wells), 61 of which are operated by the Company. As of June 30, 1996, Portilla and Happy had total proved reserves of 4,314 MBOE (18.4% natural gas) with an aggregate PV-10 of $30.2 million, 99.8% of which was attributable to proved developed reserves. The Portilla Plant had natural gas processing capacity of approximately 20.0 MMcf per day at June 30, 1996. Item 5. OTHER EVENTS A. SENIOR NOTE OFFERING SALE OF NOTES. On November 14, 1996, Abraxas and Canadian Abraxas consummated the offering of $215 million of 11.5% senior notes due 2004 (the "Notes"). Interest on the Notes will accrue from their date of original issuance (the "Issue Date") and will be payable semi-annually in arrears on May 1 and November 1 of each year, commencing on May 1, 1997, at the rate of 11.5% per annum. The Notes will be redeemable, in whole or in part, at the option of Abraxas and Canadian Abraxas, on or after November 1, 2000, at the redemption prices set forth below, plus accrued and unpaid interest to the date of redemption, if redeemed during the 12-month period commencing on November 1 of the years set forth below: Year Percentage 2000 105.75% 2001 102.875 2002 and thereafter 100.00% In addition, at any time on or prior to November 1, 1999, Abraxas and Canadian Abraxas may, at their option, redeem up to 35% of the aggregate principal amount of the Notes originally issued with the net cash proceeds of one or more equity offerings, at a redemption price equal to 111.5% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest to the date of redemption; provided, however, that, after giving effect to any such redemption, at least $139.75 million aggregate principal amount of Notes remains outstanding. The Notes are general unsecured obligations of Abraxas and Canadian Abraxas and will rank pari passu in right of payment to all existing and future unsubordinated indebtedness of Abraxas and Canadian Abraxas. The Notes rank senior in right of payment to all future subordinated indebtedness of Abraxas and Canadian Abraxas. The Notes are, however, effectively subordinated to secured indebtedness of Abraxas and Canadian Abraxas to the extent of the value of the assets securing such indebtedness. The Notes are unconditionally guaranteed, jointly and severally, by certain of Abraxas' and Canadian Abraxas' future subsidiaries (the "Subsidiary Guarantors"). The guarantees are general unsecured obligations of the Subsidiary Guarantors and rank pari passu in right of payment to all unsubordinated indebtedness of the Subsidiary Guarantors and senior in right of payment to all subordinated indebtedness of the Subsidiary Guarantors. The Guarantees are effectively subordinated to secured indebtedness of the Subsidiary Guarantors to the extent of the value of the assets securing such indebtedness. As of the date of this Report, Abraxas, Canadian Abraxas and the Subsidiary Guarantors have no secured indebtedness outstanding. Upon a Change of Control (as defined in the Indenture governing the Notes), each holder of the Notes will have the right to require Abraxas and Canadian Abraxas to repurchase all or a portion of such holder's Notes at a redemption price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of repurchase. In addition, Abraxas and Canadian Abraxas will be obligated to offer to repurchase the Notes at 100% of the principal amount thereof plus accrued and unpaid interest to the date of repurchase in the event of certain asset sales. USE OF PROCEEDS. The net proceeds to Abraxas and Canadian Abraxas from the offering of the Notes were approximately $207.0 million after deducting underwriting discounts and estimated offering expenses payable by Abraxas and Canadian Abraxas. Abraxas and Canadian Abraxas used the net proceeds to (1) repay all amounts outstanding under its credit agreement dated September 30, 1996 with Bankers Trust Company ("BT") and other lenders in the amount of $85.0 million, (2) acquire the outstanding capital stock of CGGS for $94.7 million, (3) acquire the Partnership Interest in Portilla - 1996 L.P. and repay certain indebtedness for $27.5 million and (4) provide working capital for general corporate purposes including future acquisitions and development of producing properties. New Credit Facility. In connection with the consummation of the offering of the Notes, Abraxas entered into an Amended and Restated Credit Agreement with Bankers Trust Company and ING (U.S.) Capital Corporation (the "New Credit Facility". The New Credit Facility provides for a $40.0 million revolving facility of which $20.0 million is initially available and is secured by substantially all of the U.S. assets of Abraxas. B. EQUITY ISSUES In a November 1995 private equity placement, the Company sold 1,330,000 units, each consisting of one share of common stock and one contingent value right ("CVR"). Under the terms of the placement, each CVR holder had the right to acquire additional shares of common stock at November 17, 1996 under certain circumstances related to the current trading value of the Company's stock. The Company had the option to extend the issue date for any additional shares based on the stock price until November 1997. On November 15, 1996 the Company notified the CVR owners that it had exercised its option and extended any CVR related share issue date until November 17, 1997 and correspondingly the target value of share price had been increased from $10 to $12.50 per share.

No service charge shall be made for any registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any transfer tax, fee or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Sections 2.10, 3.04, 4.15, 4.16 or 9.05, in which event the Issuers shall be responsible for the payment of such taxes). The Registrar or co-Registrar shall not be required to register the transfer of or exchange of any Note (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Note being redeemed in part. Any Holder of a beneficial interest in a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Notes may be effected only through a book entry system maintained by the Holder of such Global Note (or its agent), and that ownership of a beneficial interest in the Note shall be required to be reflected in a book entry system. 29 145385.01 SECTION 2.07. Replacement Notes. If a mutilated Note is surrendered to the Trustee or if the Holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Issuers shall issue and the Trustee shall authenticate a replacement Note and the Subsidiary Guarantors shall execute a Guarantee thereon if the Trustee's requirements are met. If required by the Trustee or the Issuers, such Holder must provide an indemnity bond or other indemnity of reasonable tenor, sufficient in the reasonable judgment of the Issuers, the Subsidiary Guarantors and the Trustee, to protect the Issuers, the Subsidiary Guarantors, the Trustee or any Agent from any loss which any of them may suffer if a Note is replaced. Every replacement Note shall constitute an additional obligation of the Issuers and the Subsidiary Guarantors. SECTION 2.08. Outstanding Notes. Notes outstanding at any time are all the Notes that have been authenticated by the Trustee except those canceled by it, those delivered to it for cancellation and those described in this Section as not outstanding. Subject to the provisions of Section 2.09, a Note does not cease to be outstanding because an Issuer or any of its Affiliates holds the Note. If a Note is replaced pursuant to Section 2.07 (other than a mutilated Note surrendered for replacement), it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender of such Note and replacement thereof pursuant to Section 2.07. If on a Redemption Date or the Maturity Date the Paying Agent holds U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the principal, premium, if any, and interest due on the Notes payable on that date and is not prohibited from paying such money to the Holders thereof pursuant to the terms of this Indenture, then on and after that date such Notes shall be deemed not to be outstanding and interest on them shall cease to accrue. 30 145385.01 SECTION 2.09. Treasury Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Issuers or an Affiliate of the Issuers shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which a Trust Officer of the Trustee actually knows are so owned shall be so considered. The Issuers shall notify the Trustee, in writing, when either of them or, to their knowledge, any of their Affiliates repurchases or otherwise acquires Notes, of the aggregate principal amount of such Notes so repurchased or otherwise acquired and such other information as the Trustee may reasonably request and the Trustee shall be entitled to rely thereon. SECTION 2.10. Temporary Notes. Until definitive Notes are ready for delivery, the Issuers may prepare and the Trustee shall authenticate temporary Notes upon receipt of a written order of the Issuers in the form of an Officers' Certificate. The Officers' Certificate shall specify the amount of temporary Notes to be authenticated and the date on which the temporary Notes are to be authenticated. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Issuers consider appropriate for temporary Notes and so indicate in the Officers' Certificate. Without unreasonable delay, the Issuers shall prepare, the Trustee shall authenticate and the Subsidiary Guarantors shall execute Guarantees on, upon receipt of a written order of the Issuers pursuant to Section 2.02, definitive Notes in exchange for temporary Notes. SECTION 2.11. Cancellation. The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent, and no one else, shall cancel and, at the written direction of the Issuers, shall dispose, in its customary manner, of all Notes surrendered for transfer, exchange, payment or cancellation. Subject to Section 2.07, the Issuers may not issue new Notes to replace Notes that they have paid or delivered to the Trustee for cancellation. If the Issuers shall acquire any of the Notes, such acquisition shall not operate as a redemption or satisfaction of the Indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation pursuant to this Section 2.11. 31 145385.01 SECTION 2.12. Defaulted Interest. The Issuers will pay interest on overdue principal from time to time on demand at the rate of interest then borne by the Notes. The Issuers shall, to the extent lawful, pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the rate of interest then borne by the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months, and, in the case of a partial month, the actual number of days elapsed. If the Issuers default in a payment of interest on the Notes, they shall pay the defaulted interest, plus (to the extent lawful) any interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which special record date shall be the fifteenth day next preceding the date fixed by the Issuers for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. The Issuers shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment (a "Default Interest Payment Date"), and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section; provided, however, that in no event shall the Issuers deposit monies proposed to be paid in respect of defaulted interest later than 11:00 a.m. New York City time of the proposed Default Interest Payment Date. At least 15 days before the subsequent special record date, the Issuers shall mail (or cause to be mailed) to each Holder, as of a recent date selected by the Issuers, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. Notwithstanding the foregoing, any interest which is paid prior to the expiration of the 30-day period set forth in Section 6.01(a) shall be paid to Holders as of the regular record date for the Interest Payment Date for which interest has not been paid. Notwithstanding the foregoing, the Issuers may make payment of any defaulted interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange. SECTION 2.13. CUSIP Number. The Issuers in issuing the Notes may use a "CUSIP" number, and, if so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuers shall promptly notify the Trustee of any change in the CUSIP number. 32 145385.01 SECTION 2.14. Deposit of Monies. Prior to 11:00 a.m. New York City time on each Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Offer Payment Date, the Issuers shall have deposited with the Paying Agent in immediately available funds money sufficient to make cash payments, if any, due on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Offer Payment Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment Date and Net Proceeds Offer Payment Date, as the case may be. SECTION 2.15. Restrictive Legends. Each Global Note and Physical Note that constitutes a Restricted Security shall bear the following legend (the "Private Placement Legend") on the face thereof until after the third anniversary of the later of the Issue Date and the last date on which an Issuer or any Affiliate of either Issuer was the owner of such Note (or any predecessor security) (or such shorter period of time as permitted by Rule 144(k) under the Securities Act or any successor provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws in the opinion of counsel for the Issuers, unless otherwise agreed by the Issuers and the Holder thereof): THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH BELOW.

IN CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN THREE YEARS AFTER THE ORIGINAL ISSUANCE OF THIS SECURITY, IF THE PROPOSED TRANSFEREE IS AN ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE ISSUERS SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. Each Global Note shall also bear the following legend on the face thereof: UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY, OR BY ANY SUCH NOMINEE OF THE DEPOSITORY, OR BY THE DEPOSITORY OR NOMINEE OF SUCH SUCCESSOR DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITORY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITORY.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN SECTION 2.17 OF THE INDENTURE. SECTION 2.16. Book-Entry Provisions for Global Security. (a) The Global Notes initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Trustee as custodian for such Depository and (iii) bear legends as set forth in Section 2.15. Members of, or participants in, the Depository ("Agent Members") shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository, or the Trustee as its custodian, or under the Global Notes, and the Depository may be treated by the Issuers, the Trustee and any Agent of the Issuers or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Trustee or any Agent of the Issuers or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note. (b) Transfers of a Global Note shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in a Global Note may be transferred or exchanged for Physical Notes in accordance with the rules and procedures of the Depository and the provisions of Section 2.17. In addition, Physical Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in a Global Note if (i) the Depository notifies the Issuers that it is unwilling or unable to continue as Depository for the Global Notes and a successor depositary is not appointed by the Issuers within 90 days of such notice or (ii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the Depository to issue Physical Notes. (c) In connection with any transfer or exchange of a portion of the beneficial interest in a Global Note to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more Physical Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial interest in 35 145385.01 the Global Note to be transferred, and the Issuers shall execute, the Subsidiary Guarantors shall execute Guarantees on, and the Trustee shall authenticate and deliver, one or more Physical Notes of like tenor and amount. (d) In connection with the transfer of an entire Global Note to beneficial owners pursuant to paragraph (b), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Issuers shall execute, the Subsidiary Guarantors shall execute Guarantees on and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in the Global Note, an equal aggregate principal amount of Physical Notes of authorized denominations. (e) Any Physical Note constituting a Restricted Security delivered in exchange for an interest in a Global Note pursuant to paragraph (b) or (c) shall, except as otherwise provided by paragraphs (a)(i)(x) and (c) of Section 2.17, bear the legend regarding transfer restrictions applicable to the Physical Notes set forth in Section 2.15. (f) The Holder of a Global Note may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Notes. SECTION 2.17. Special Transfer Provisions. (a) Transfers to Non-QIB Institutional Accredited Investors and Non-U.S. Persons. The following provisions shall apply with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to any Institutional Accredited Investor which is not a QIB or to any Non-U.S. Person: (i) the Registrar shall register the transfer of any Note constituting a Restricted Security, whether or not such Note bears the Private Placement Legend, if (x) the requested transfer is after the third anniversary of the Issue Date (provided, however, that neither the Company nor any Affiliate of the Company has held any beneficial interest in such Note, or portion thereof, at any time on or prior to the third anniversary of the Issue Date) or (y) (1) in the case of a transfer to an Institutional Accredited Investor which is not a QIB (excluding Non-U.S. Persons), the proposed transferee has delivered to the Registrar a certificate substantially in the form of Exhibit C hereto or (2) in the case of a transfer to a Non-U.S. Person, the proposed transferor has delivered to the Registrar a certificate substantially in the form of Exhibit D hereto; and (ii) if the proposed transferor is an Agent Member holding a beneficial interest in the Global Note, upon receipt by the Registrar of (x) the certificate, if any, required by paragraph (i) above and (y) written instructions given in accordance with the Depository's and the Registrar's procedures, whereupon 36 145385.01 (a) the Registrar shall reflect on its books and records the date and (if the transfer does not involve a transfer of outstanding Physical Notes) a decrease in the principal amount of such Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and (b) the Issuers shall execute, the Subsidiary Guarantors shall execute the Guarantees on and the Trustee shall authenticate and deliver one or more Physical Notes of like tenor and amount. (b) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Note constituting a Restricted Security to a QIB (excluding transfers to Non-U.S. Persons): (i) the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Note stating, or has otherwise advised the Issuers and the Registrar in writing, that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed the certification provided for on the form of Note stating, or has otherwise advised the Issuers and the Registrar in writing, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Issuers as it has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; and (ii) if the proposed transferee is an Agent Member, and the Notes to be transferred consist of Physical Notes which after transfer are to be evidenced by an interest in a Global Note, upon receipt by the Registrar of written instructions given in accordance with the Depository's and the Registrar's procedures, the Registrar shall reflect on its books and records the date and an increase in the principal amount of such Global Note in an amount equal to the principal amount of the Physical Notes to be transferred, and the Trustee shall cancel the Physical Notes so transferred. (c) Private Placement Legend. Upon the transfer, exchange or replacement of Notes not bearing the Private Placement Legend, the Registrar shall deliver Notes that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Notes bearing the Private Placement Legend, the Registrar shall deliver only Notes that bear the Private Placement Legend unless (i) the requested transfer is after the third anniversary of the Issue Date (provided, however, that neither Issuer nor any Affiliate of the Issuers has held any beneficial interest in such Note, or portion thereof, at any time prior to or on the third anniversary of the Issue Date), or (ii) there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuers and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. 37 145385.01 (d) General. By its acceptance of any Note bearing the Private Placement Legend, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Note only as provided in this Indenture. The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.16 or this Section 2.17. The Issuers shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time during the Registrar's normal business hours upon the giving of reasonable written notice to the Registrar. (e) Transfers of Notes Held by Affiliates. Any certificate (i) evidencing a Note that has been transferred to an Affiliate of an Issuer within three years after the Issue Date, as evidenced by a notation on the Assignment Form for such transfer or in the representation letter delivered in respect thereof or (ii) evidencing a Note that has been acquired from an Affiliate (other than by an Affiliate) in a transaction or a chain of transactions not involving any public offering, shall, until three years after the last date on which either Issuer or any Affiliate of either Issuer was an owner of such Note, in each case, bear a legend in substantially the form set forth in Section 2.15 hereof, unless otherwise agreed by the Issuers (with written notice thereof to the Trustee). SECTION 2.18. Liquidated Damages Under Registration Rights Agreement. Under certain circumstances, the Issuers shall be obligated to pay certain liquidated damages to the Holders, all as set forth in Section 4 of the Registration Rights Agreement. The terms thereof are hereby incorporated herein by reference. ARTICLE THREE REDEMPTION SECTION 3.01. Notices to Trustee. If the Company elects to redeem Notes pursuant to Paragraph 6 of the Notes, it shall notify the Trustee and the Paying Agent in writing of the Redemption Date and the principal amount of the Notes to be redeemed. The Company shall give each notice provided for in this Section 3.01 60 days before the Redemption Date (unless a shorter notice period shall be satisfactory to the Trustee, as evidenced in a writing signed on behalf of the Trustee), together with an Officers' Certificate stating that such redemption shall comply with the conditions contained herein and in the Notes. 38 145385.01 SECTION 3.02. Selection of Notes To Be Redeemed. In the event that less than all of the Notes are to be redeemed at any time, selection of such Notes, or portions thereof, for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not then listed on a national securities exchange, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate; provided, however, that no Notes of a principal amount of $1,000 or less shall be redeemed in part; and provided, further, that if a partial redemption is made with the proceeds of an Equity Offering, selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of DTC), unless such method is otherwise prohibited. Notice of redemption shall be mailed by first-class mail at least 30 but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at its registered address. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the applicable Redemption Date, interest will cease to accrue on Notes or portions thereof called for redemption as long as the Issuers have deposited with the Paying Agent for the Notes funds in satisfaction of the applicable Redemption Price. SECTION 3.03. Optional Redemption. The Notes will be redeemable, at the Issuers' option, in whole at any time or in part from time to time, on and after November 1, 2000, upon not less than 30 nor more than 60 days' notice, at the following Redemption Prices (expressed as percentages of the principal amount thereof) if redeemed during the twelve-month period commencing on November 1 of the years set forth below, plus, in each case, accrued and unpaid interest, if any, thereon to the date of redemption: Year Percentage 2000............................ 105.750% 2001............................ 102.875% 2002 and thereafter.... 100.000% At any time, or from time to time, on or prior to __________, 1999, the Issuers may, at their option, use all or a portion of the net cash proceeds of one or more Equity Offerings (as defined below) to redeem up to 35% of the aggregate principal amount of the Notes originally issued at a Redemption Price equal to 111.5% of the aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, thereon to the date of redemption; provided, however, that at least $139.75 million aggregate principal amount of Notes remains outstanding immediately after giving effect to any such redemption (it being expressly agreed that for purposes of determining whether this 39 145385.01 condition is satisfied, Notes owned by either Issuer or any of their Affiliates shall be deemed not to be outstanding). In order to effect the foregoing redemption with the proceeds of any Equity Offering, the Issuers shall make such redemption not more than 60 days after the consummation of any such Equity Offering. SECTION 3.04. Notice of Redemption. At least 30 days but not more than 60 days before a Redemption Date, the Issuers shall mail or cause to be mailed a notice of redemption by first class mail to each Holder of Notes to be redeemed at its registered address, with a copy to the Trustee and any Paying Agent. At the Issuers' request, the Trustee shall give the notice of redemption in the Issuers' name and at the Company's expense.

SECTION 3.05. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.04, such notice of redemption shall be irrevocable and Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price plus accrued interest as of such date, if any. Upon surrender to the Trustee or Paying Agent, such Notes called for redemption shall be paid at the Redemption Price plus accrued interest thereon to the Redemption Date, but installments of interest, the maturity of which is on or prior to the Redemption Date, shall be payable to Holders of record at the close of business on the relevant record dates referred to in the Notes. Interest shall accrue on or after the Redemption Date and shall be payable only if the Issuers default in payment of the Redemption Price. SECTION 3.06. Deposit of Redemption Price. On or before the Redemption Date and in accordance with Section 2.14, the Issuers shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay the Redemption Price plus accrued interest, if any, of all Notes to be redeemed on that date. The Paying Agent shall promptly return to the Company any U.S. Legal Tender so deposited which is not required for that purpose, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven. Unless the Issuers fail to comply with the preceding paragraph and default in the payment of such Redemption Price plus accrued interest, if any, interest on the Notes to be redeemed will cease to accrue on and after the applicable Redemption Date, whether or not such Notes are presented for payment. SECTION 3.07. Notes Redeemed in Part. Upon surrender of a Note that is to be redeemed in part, the Trustee shall authenticate for the Holder a new Note or Notes equal in principal amount to the unredeemed portion of the Note surrendered. 41 145385.01 ARTICLE FOUR COVENANTS SECTION 4.01.

(c) Notwithstanding anything to the contrary contained in this Indenture, the Issuers may, to the extent they are required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments hereunder. SECTION 4.02. Maintenance of Office or Agency. The Issuers shall maintain the office or agency required under Section 2.03. The Issuers shall give prior written notice to the Trustee of the location, and any change in the location, of such office or agency.

Payment of Taxes and Other Claims. The Issuers shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all material taxes, assessments and governmental charges (including withholding taxes and any penalties, interest and additions to taxes) levied or imposed upon either of them or any of their Subsidiaries or properties of either of them or any of their Subsidiaries and (ii) all material lawful claims for labor, materials and supplies that, if unpaid, might by law become a Lien upon the property of the Issuers or any of their Subsidiaries; provided, however, that the Issuers shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate negotiations or proceedings properly instituted and diligently conducted for which adequate reserves, to the extent required under GAAP, have been taken. SECTION 4.05. Maintenance of Properties and Insurance. (a) Each Issuer shall, and shall cause each of the Restricted Subsidiaries to, maintain all properties used or useful in the conduct of its business in good working order and condition (subject to ordinary wear and tear) and make all necessary repairs, renewals, replacements, additions, betterments and improvements thereto and actively conduct and carry on its business; provided, however, that nothing in this Section 4.05 shall prevent an Issuer or any of the Restricted Subsidiaries from discontinuing the operation and maintenance of any of its properties, if such discontinuance is (i) in the ordinary course of business pursuant to customary business terms or (ii) in the good faith judgment of the respective Boards of Directors or other governing body of such Issuer or Restricted Subsidiary, as the case may be, desirable in the conduct of their respective businesses and is not disadvantageous in any material respect to the Holders. (b) The Issuers shall provide or cause to be provided, for themselves and each of the Restricted Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of the Company, are adequate and appropriate for the conduct of the business of the Company and its Restricted Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States of America, Canada or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the good faith judgment of the Company, for companies similarly situated in the industry. 43 145385.01 SECTION 4.06. Compliance Certificate; Notice of Default. (a) The Issuers shall deliver to the Trustee, within 105 days after the end of their respective fiscal quarters and fiscal years, an Officers' Certificate of each of the Issuers (provided, however, that one of the signatories to each such Officers' Certificate shall be the respective Issuer's principal executive officer, principal financial officer or principal accounting officer), as to such Officers' knowledge, without independent investigation, of such Issuer's compliance with all conditions and covenants under this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and in the event any Default of the Issuers exists, such Officers shall specify the nature of such Default. Each such Officers' Certificate shall also notify the Trustee should such Issuer elect to change the manner in which it fixes its fiscal year end. (b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the annual financial statements delivered pursuant to Section 4.08 shall be accompanied by a written report of the Company's independent certified public accountants (who shall be a firm of established national reputation) stating (A) that their audit examination has included a review of the terms of this Indenture and the form of the Notes as they relate to accounting matters, and (B) whether, in connection with their audit examination, any Default or Event of Default has come to their attention and if such a Default or Event of Default has come to their attention, specifying the nature and period of existence thereof; provided, however, that, without any restriction as to the scope of the audit examination, such independent certified public accountants shall not be liable by reason of any failure to obtain knowledge of any such Default or Event of Default that would not be disclosed in the course of an audit examination conducted in accordance with generally accepted auditing standards. (c) (i) If any Default or Event of Default has occurred and is continuing or (ii) if any Holder seeks to exercise any remedy hereunder with respect to a claimed Default under this Indenture or the Notes, the Company shall deliver to the Trustee, at its address set forth in Section 10.02 hereof, by registered or certified mail or by facsimile transmission followed by hard copy by registered or certified mail an Officers' Certificate specifying such event, notice or other action within 10 days of its becoming aware of such occurrence. 44 145385.01 SECTION 4.07. Compliance with Laws. The Issuers shall comply, and shall cause each of their Subsidiaries to comply, with all applicable statutes, rules, regulations, orders and restrictions of the United States of America, all states and municipalities thereof, and of any governmental department, commission, board, regulatory authority, bureau, agency and instrumentality of the foregoing, in respect of the conduct of their respective businesses and the ownership of their respective properties, except for such noncompliances as could not singly or in the aggregate reasonably be expected to have a material adverse effect on the financial condition, business, prospects or results of operations of the Company and its Subsidiaries taken as a whole. SECTION 4.08. Reports to Holders. The Company will deliver to the Trustee within 15 days after filing the same with the Commission, copies of the quarterly and annual reports and of the information, documents and other reports, if any, which the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act. Notwithstanding that the Company may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company will file with the Commission, to the extent permitted, and provide the Trustee and Holders with such annual reports and such information, documents and other reports specified in Sections 13 and 15(d) of the Exchange Act. The Company will also comply with the other provisions of Section 314(a) of the TIA. SECTION 4.09. Waiver of Stay, Extension or Usury Laws. The Issuers covenant (to the extent that they may lawfully do so) that they will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive the Issuers from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that they may lawfully do so) the Issuers hereby expressly waive all benefit or advantage of any such law, and covenant that they will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. SECTION 4.10. Limitation on Restricted Payments. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, (i) declare or pay any dividend or make any distribution (other than dividends or distributions payable solely in Qualified Capital Stock of the Company) on or in respect of shares of the Company's Capital Stock to 45 145385.01 holders of such Capital Stock; (ii) purchase, redeem or otherwise acquire or retire for value any Capital Stock of the Company or any warrants, rights or options to purchase or acquire shares of any class of such Capital Stock other than through the exchange therefor solely of Qualified Capital Stock of the Company or warrants, rights or options to purchase or acquire shares of Qualified Capital Stock of the Company; (iii) make any principal payment on, purchase, defease, redeem, prepay, decrease or otherwise acquire or retire for value, prior to any scheduled final maturity, scheduled repayment or scheduled sinking fund payment, any Indebtedness of the Company or a Subsidiary Guarantor that is subordinate or junior in right of payment to the Notes or such Subsidiary Guarantor's Guarantee, as the case may be; or (iv) make any Investment (other than a Permitted Investment) (each of the foregoing actions set forth in clauses (i), (ii), (iii) and (iv) being referred to as a "Restricted Payment"), if at the time of such Restricted Payment or immediately after giving effect thereto, (a) a Default or an Event of Default shall have occurred and be continuing, (b) the Company is not able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in compliance with Section 4.12; provided, however, that notwithstanding the provisions of clause (i) (a) of Section 4.12, for purposes of determining whether the Company could incur such additional Indebtedness pursuant to this clause (b), the Consolidated EBITDA Coverage Ratio which shall be required shall be at least 2.5 to 1.0, or (c) the aggregate amount of Restricted Payments (including such proposed Restricted Payment) made subsequent to the Issue Date (the amount expended for such purposes, if other than in cash, being the fair market value of such property as determined reasonably and in good faith by the Board of Directors of the Company) shall exceed the sum of: (A) 50% of the cumulative Consolidated Net Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of such loss) of the Company earned subsequent to the Issue Date and on or prior to the last date of the Company's fiscal quarter immediately preceding such Restricted Payment (the "Reference Date") (treating such period as a single accounting period); plus (B) 100% of the aggregate net cash proceeds received by the Company from any Person (other than a Restricted Subsidiary of the Company) from the issuance and sale subsequent to the Issue Date and on or prior to the Reference Date of Qualified Capital Stock of the Company, plus (C) without duplication of any amounts included in the immediately preceding subclause (B), 100% of the aggregate net cash proceeds of any equity contribution received by the Company from a holder of the Company's Capital Stock 46 145385.01 (excluding in the case of the immediately preceding clause (B) and this clause (C), any net cash proceeds from an Equity Offering to the extent used to redeem the Notes); plus (D) an amount equal to the net reduction in Investments in Unrestricted Subsidiaries resulting from dividends, interest payments, repayments of loans or advances, or other transfers of cash, in each case to the Company or to any Restricted Subsidiary of the Company from Unrestricted Subsidiaries (but without duplication of any such amount included in calculating cumulative Consolidated Net Income of the Company), or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries (in each case valued as provided in Section 4.14), not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary and which was treated as a Restricted Payment hereunder; plus (E) without duplication of the immediately preceding subclause (D), an amount equal to the lesser of the cost or net cash proceeds received upon the sale or other disposition of any Investment made after the Issue Date which had been treated as a Restricted Payment (but without duplication of any such amount included in calculating cumulative Consolidated Net Income of the Company); plus (F) $5,000,000. Notwithstanding the foregoing, the provisions set forth above will not prohibit: (1) The payment of any dividend or redemption payment within 60 days after the date of declaration of such dividend or applicable redemption if the dividend or redemption payment, as the case may be, would have been permitted on the date of declaration; (2) If no Default or Event of Default shall have occurred and be continuing, the acquisition of any shares of Capital Stock of the Company, either (a) solely in exchange for shares of Qualified Capital Stock of the Company or (b) through the application of net proceeds of a substantially concurrent sale for cash (other than to a Restricted Subsidiary of the Company) of shares of Qualified Capital Stock of the Company; (3) If no Default or Event of Default shall have occurred and be continuing, the acquisition of any Indebtedness of the Company or Subsidiary Guarantor that is subordinate or junior in right of payment to the Notes or such Subsidiary Guarantor's Guarantee, as the case may be, either (a) solely in exchange for shares of Qualified Capital Stock of the Company or (b) through the application of the net proceeds of a substantially concurrent sale for cash (other than to a Restricted Subsidiary of the Company) of (i) shares of Qualified Capital Stock of the Company or (ii) Refinancing Indebtedness; 47 145385.01 (4) If no Default or Event of Default shall have occurred and be continuing, the payment of dividends in respect of the Company's Series 1995-B Preferred Stock in an amount not to exceed $400,000 in any one year; (5) The initial designation of Cascade, Grey Wolf and Western as Unrestricted Subsidiaries; and (6) The payment of such portion of the CGGS purchase price, if any, as shall have been placed in an escrow account to the former shareholders of CGGS. In determining the aggregate amount of Restricted Payments made subsequent to the Issue Date in accordance with clause (c) of this Section 4.10, amounts expended pursuant to clauses (1), (2)(b) and (5) shall be included in such calculation. SECTION 4.11. Limitation on Transactions with Affiliates. (i) The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, enter into, amend or permit or suffer to exist any transaction or series of related transactions (including, without limitation, the purchase, sale, lease or exchange of any property, the guaranteeing of any Indebtedness or the rendering of any service) with or for the benefit of any of their respective Affiliates (an "Affiliate Transaction"), other than (a) Affiliate Transactions permitted under paragraph (ii) of this Section 4.11 and (b) Affiliate Transactions that are on terms that are fair and reasonable to the Company or the applicable Restricted Subsidiary and are no less favorable to the Company or the applicable Restricted Subsidiary than those that might reasonably have been obtained in a comparable transaction at such time on an arm's-length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary. All Affiliate Transactions (and each series of related Affiliate Transactions which are similar or part of a common plan) involving aggregate payments or other property with a fair market value in excess of $1,000,000 shall be approved by the Board of Directors of the Company, such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with the foregoing provisions. If the Company or any Restricted Subsidiary enters into an Affiliate Transaction (or a series of related Affiliate Transactions related to a common plan) that involves an aggregate fair market value of more than $10,000,000, the Company shall, prior to the consummation thereof, obtain a favorable opinion as to the fairness of such transaction or series of related transactions to the Company or the relevant Restricted Subsidiary, as the case may be, from a financial point of view, from an Independent Advisor and file the same with the Trustee. (ii) The restrictions set forth in clause (i) shall not apply to (a) reasonable fees and compensation paid to and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any Restricted Subsidiary as determined in good faith by the Board of Directors or senior management of the Company or such Restricted Subsidiary, as the case may be; (b) transactions exclusively between or among 48 145385.01 the Company and any of its Restricted Subsidiaries or exclusively between or among such Restricted Subsidiaries; provided, however, that such transactions are not otherwise prohibited hereunder; (c) Restricted Payments permitted hereunder; and (iv) the payment of such portion of the CGGS purchase price, if any, as shall have been held in escrow to the former shareholders of CGGS. SECTION 4.12. Limitation on Incurrence of Additional Indebtedness. Other than Permitted Indebtedness, the Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume, guarantee, acquire, become liable, contingently or otherwise, with respect to, or otherwise become responsible for payment of (collectively, "incur") any Indebtedness; provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time of or as a consequence of the incurrence of any such Indebtedness, the Company and the Restricted Subsidiaries or any of them may incur Indebtedness (including, without limitation, Acquired Indebtedness), in each case, if on the date of the incurrence of such Indebtedness, after giving pro forma effect to the incurrence thereof and the receipt and application of the proceeds therefrom, (i) both (a) the Company's Consolidated EBITDA Coverage Ratio would have been greater than 2.25 to 1.0 if such proposed incurrence is on or prior to November 1, 1997 and at least equal to 2.5 to 1.0 if such proposed incurrence is thereafter and (b) the Company's Adjusted Consolidated Net Tangible Assets are equal to or greater than 150% of the aggregate consolidated Indebtedness of the Company and its Restricted Subsidiaries or (ii) the Company's Adjusted Consolidated Net Tangible Assets are equal to or greater than 200% of the aggregate consolidated Indebtedness of the Company and its Restricted Subsidiaries. For purposes of determining any particular amount of Indebtedness under this Section 4.12, guarantees of Indebtedness otherwise included in the determination of such amount shall not also be included. Indebtedness of a Person existing at the time such Person becomes a Restricted Subsidiary (whether by merger, consolidation, acquisition of Capital Stock or otherwise) or is merged with or into the Company or any Restricted Subsidiary or which is secured by a Lien on an asset acquired by the Company or a Restricted Subsidiary (whether or not such Indebtedness is assumed by the acquiring Person) shall be deemed incurred at the time the Person becomes a Restricted Subsidiary or at the time of the asset acquisition, as the case may be. The Company will not, and will not permit any Subsidiary Guarantor to incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated in right of payment to any other Indebtedness of the Company or such Subsidiary Guarantor unless such Indebtedness is also by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate in right of payment to the Notes or the Guarantee of such Subsidiary Guarantor, as the case may be, pursuant to subordination provisions that are substantively identical to the subordination 49 145385.01 provisions of such Indebtedness (or such agreement) that are most favorable to the holders of any other Indebtedness of the Company or such Subsidiary Guarantor, as the case may be. SECTION 4.13. Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to: (a) pay dividends or make any other distributions on or in respect of its Capital Stock; (b) make loans or advances, or pay any Indebtedness or other obligation owed, to the Company or any other Restricted Subsidiary; (c) guarantee any Indebtedness or any other obligation of the Company or any Restricted Subsidiary; or (d) transfer any of its property or assets to the Company or any other Restricted Subsidiary (each such encumbrance or restriction, a "Payment Restriction"), except for such encumbrances or restrictions existing under or by reason of: (1) applicable law; (2) this Indenture; (3) the New Credit Facility; (4) customary non-assignment provisions of any contract or any lease governing a leasehold interest of any Restricted Subsidiary; (5) any instrument governing Acquired Indebtedness, which encumbrance or restriction is not applicable to such Restricted Subsidiary, or the properties or assets of such Restricted Subsidiary, other than the Person or the property or assets of the Person so acquired; (6) agreements existing on the Issue Date to the extent and in the manner such agreements are in effect on the Issue Date; (7) customary restrictions with respect to a Restricted Subsidiary of the Company pursuant to an agreement that has been entered into for the sale or disposition of Capital Stock or assets of such Restricted Subsidiary to be consummated in accordance with the terms of this Indenture solely in respect of the assets or Capital Stock to be sold or disposed of; (8) any instrument governing a Permitted Lien, to the extent and only to the extent such instrument restricts the transfer or other disposition of assets subject to such Permitted Lien; or (9) an agreement governing Refinancing Indebtedness incurred to Refinance the Indebtedness issued, assumed or incurred pursuant to an agreement referred to in clause (2), (3), (5) or (6) above; provided, however, that the provisions relating to such encumbrance or restriction contained in any such Refinancing Indebtedness are no less favorable to the Holders in any material respect as determined by the Board of Directors of the Company in their reasonable and good faith judgment than the provisions relating to such encumbrance or restriction contained in the applicable agreement referred to in such clause (2), (3), (5), or (6). 50 145385.01 SECTION 4.14. Limitation on Restricted and Unrestricted Subsidiaries. The Board of Directors may, if no Default or Event of Default shall have occurred and be continuing or would arise therefrom, designate an Unrestricted Subsidiary to be a Restricted Subsidiary; provided, however, that (i) any such redesignation shall be deemed to be an incurrence as of the date of such redesignation by the Company and its Restricted Subsidiaries of the Indebtedness (if any) of such redesignated Subsidiary for purposes of Section 4.12, (ii) unless such redesignated Subsidiary shall not have any Indebtedness outstanding, other than Indebtedness which would be Permitted Indebtedness, no such designation shall be permitted if immediately after giving effect to such redesignation and the incurrence of any such additional Indebtedness the Company could not incur $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.12 and (iii) such Subsidiary assumes by execution of a supplemental indenture all of the obligations of a Subsidiary Guarantor under a Guarantee. The Board of Directors of the Company also may, if no Default or Event of Default shall have occurred and be continuing or would arise therefrom, designate any Restricted Subsidiary to be an Unrestricted Subsidiary if (i) such designation is at that time permitted under Section 4.10 and (ii) immediately after giving effect to such designation, the Company could incur $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.12. Any such designation by the Board of Directors shall be evidenced to the Trustee by the filing with the Trustee of a certified copy of the resolution of the Board of Directors giving effect to such designation or redesignation and an Officers' Certificate certifying that such designation or redesignation complied with the foregoing conditions and setting forth in reasonable detail the underlying calculations. In the event that any Restricted Subsidiary is designated an Unrestricted Subsidiary in accordance with this Section 4.14, such Restricted Subsidiary's Guarantee will be released. For purposes of Section 4.10, (i) an "Investment" shall be deemed to have been made at the time any Restricted Subsidiary is designated as an Unrestricted Subsidiary in an amount (proportionate to the Company's equity interest in such Subsidiary) equal to the net worth of such Restricted Subsidiary at the time that such Restricted Subsidiary is designated as an Unrestricted Subsidiary; (ii) at any date the aggregate amount of all Restricted Payments made as Investments since the Issue Date shall exclude and be reduced by an amount (proportionate to the Company's equity interest in such Subsidiary) equal to the net worth of any Unrestricted Subsidiary at the time that such Unrestricted Subsidiary is designated a Restricted Subsidiary, not to exceed, in the case of any such redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, the amount of Investments previously made by the Company and the Restricted Subsidiaries in such Unrestricted Subsidiary (in each case (i) and (ii) "net worth" to be calculated based upon the fair market value of the assets of such Subsidiary as of any such date of designation); and (iii) any property transferred to or from an Unrestricted Subsidiary shall be valued at its fair market value at the time of such transfer. Notwithstanding the foregoing, the Board of Directors may not designate any 51 145385.01 Subsidiary of the Company to be an Unrestricted Subsidiary if, after such designation, (a) the Company or any Restricted Subsidiary (i) provides credit support for, or a guarantee of, any Indebtedness of such Subsidiary (including any undertaking, agreement or instrument evidencing such Indebtedness) or (ii) is directly or indirectly liable for any Indebtedness of such Subsidiary or (b) such Subsidiary owns any Capital Stock of, or owns or holds any Lien on any property of, any Restricted Subsidiary which is not a Subsidiary of the Subsidiary to be so designated. Notwithstanding the foregoing, the provisions set forth above will not prohibit the initial designation of each of Grey Wolf, Cascade and Western as Unrestricted Subsidiaries. Subsidiaries of the Company that are not designated by the Board of Directors as Restricted or Unrestricted Subsidiaries will be deemed to be Restricted Subsidiaries. Notwithstanding any provisions of this Section 4.14, all Subsidiaries of an Unrestricted Subsidiary will be Unrestricted Subsidiaries. SECTION 4.15. Change of Control. (a) Upon the occurrence of a Change of Control, each Holder will have the right to require that the Issuers repurchase all or a portion of such Holder's Notes pursuant to the offer described below (the "Change of Control Offer"), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to the date of purchase. (b) Within 30 days following the date upon which the Change of Control occurred, the Issuers must send, by first class mail, a notice to each Holder at such Holder's last registered address, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. The notice to the Holders shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Change of Control Offer. Such notice shall state: (i) that the Change of Control Offer is being made pursuant to this Section 4.15, that all Notes tendered and not withdrawn will be accepted for payment and that the Change of Control Offer shall remain open for a period of 20 Business Days or such longer period as may be required by law; (ii) the purchase price (including the amount of accrued interest) and the purchase date (which shall be no earlier than 30 days nor later than 45 days from the date such notice is mailed, other than as may be required by law) (the "Change of Control Payment Date"); (iii) that any Note not tendered will continue to accrue interest; (iv) that, unless the Issuers default in making payment therefor, any Note accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Payment Date; 52 145385.01 (v) that Holders electing to have a Note purchased pursuant to a Change of Control Offer will be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date; (vi) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the second Business Day prior to the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Notes purchased; (vii) that Holders whose Notes are purchased only in part will be issued new Notes in a principal amount equal to the unpurchased portion of the Notes surrendered; provided, however, that each Note purchased and each new Note issued shall be in an original principal amount of $1,000 or integral multiples thereof; and (viii) the circumstances and relevant facts regarding such Change of Control. On or before the Change of Control Payment Date, the Issuers shall (i) accept for payment Notes or portions thereof tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent in accordance with Section 2.14 U.S. Legal Tender sufficient to pay the purchase price plus accrued interest, if any, of all Notes so tendered and (iii) deliver to the Trustee Notes so accepted together with an Officers' Certificate stating the Notes or portions thereof being purchased by the Issuers. Upon receipt by the Paying Agent of the monies specified in clause (ii) above and a copy of the Officers' Certificate specified in clause (iii) above, the Paying Agent shall promptly mail to the Holders of Notes so accepted payment in an amount equal to the purchase price plus accrued interest, if any, and the Trustee shall promptly authenticate and mail to such Holders new Notes equal in principal amount to any unpurchased portion of the Notes surrendered. Any Notes not so accepted shall be promptly mailed by the Company to the Holder thereof. For purposes of this Section 4.15, the Trustee shall act as the Paying Agent. The Issuers shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer at the Change of Control Purchase Price, at the same times and otherwise in compliance with the requirements applicable to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. Neither the Board of Directors of the Company nor the Trustee may waive the 53 145385.01 provisions of this Section 4.15 relating to the Issuers' obligation to make a Change of Control Offer. The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.15, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached their obligations under the provisions of this Section 4.15 by virtue thereof. SECTION 4.16. Limitation on Asset Sales. (a) The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (i) the Company or the applicable Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets sold or otherwise disposed of (as determined in good faith by the Company's Board of Directors or senior management of the Company); (ii) (a) at least 70% of the consideration received by the Company or the Restricted Subsidiary, as the case may be, from such Asset Sale shall be in the form of cash or Cash Equivalents and is received at the time of such disposition and (b) at least 15% of such consideration received if in a form other than cash or Cash Equivalents is converted into or exchanged for cash or Cash Equivalents within 120 days of such disposition; and (iii) upon the consummation of an Asset Sale, the Company shall apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof either (a) to repay or prepay Indebtedness outstanding under the New Credit Facility, including, without limitation, a permanent reduction in the related commitment, (b) to repay or prepay any Indebtedness of the Company that is secured by a Lien permitted to be incurred pursuant to Section 4.18, (c) to make an investment in properties or assets that replace the properties or assets that were the subject of such Asset Sale or in properties or assets that will be used in the business of the Company and its Restricted Subsidiaries as existing on the Issue Date or in businesses reasonably related thereto ("Replacement Assets"), (d) to an investment in Crude Oil and Natural Gas Related Assets or (e) a combination of prepayment and investment permitted by the foregoing clauses (iii)(a) through (iii)(d). On the 366th day after an Asset Sale or such earlier date, if any, as the Board of Directors of the Company determines not to apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses (iii)(a) through (iii)(d) of the next preceding sentence (each a "Net Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds which have been received by the Company or such Restricted Subsidiary but which have 54 145385.01 not been applied on or before such Net Proceeds Offer Trigger Date as permitted in clauses (iii)(a) through (iii)(d) of the next preceding sentence (each a "Net Proceeds Offer Amount") shall be applied by the Company or such Restricted Subsidiary, as the case may be, to make an offer to purchase (a "Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not less than 30 nor more than 45 days following the applicable Net Proceeds Offer Trigger Date, from all Holders on a pro rata basis, that principal amount of Notes purchasable with the Net Proceeds Offer Amount at a price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest, if any, thereon to the date of purchase; provided, however, that if at any time any non-cash consideration received by the Company or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then such conversion or disposition shall be deemed to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be applied in accordance with this Section 4.16. The Company may defer the Net Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $5,000,000 resulting from one or more Asset Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and not just the amount in excess of $5,000,000, shall be applied as required pursuant to this paragraph). In the event of the transfer of substantially all (but not all) of the property and assets of the Company and its Restricted Subsidiaries as an entirety to a Person in a transaction permitted under Section 5.01, the successor corporation shall be deemed to have sold the properties and assets of the Company and its Restricted Subsidiaries not so transferred for purposes of this Section 4.16, and shall comply with the provisions of this Section 4.16 with respect to such deemed sale as if it were an Asset Sale. In addition, the fair market value of such properties and assets of the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash Proceeds for purposes of this Section 4.16. Notwithstanding the two immediately preceding paragraphs, the Company and its Restricted Subsidiaries will be permitted to consummate an Asset Sale without complying with such paragraphs to the extent (a) the consideration for such Asset Sale constitutes Replacement Assets and/or Crude Oil and Natural Gas Related Assets and (b) such Asset Sale is for fair market value; provided, however, that any consideration not constituting Replacement Assets and Crude Oil and Natural Gas Related Assets received by the Company or any of its Restricted Subsidiaries in connection with any Asset Sale permitted to be consummated under this paragraph shall constitute Net Cash Proceeds subject to the provisions of the two immediately preceding paragraphs. (b) Subject to the deferral of the Net Proceeds Offer contained in clause (a)(iii) above, each notice of a Net Proceeds Offer pursuant to this Section 4.16 shall be mailed or caused to be mailed, by first class mail, by the Issuers not more than 30 days after the Net Proceeds Offer Trigger Date to all Holders at their last registered addresses, with a copy to the Trustee.

The Paying Agent shall promptly mail to the Holders of Notes so accepted payment in an amount equal to the purchase price plus accrued interest, if any. For purposes of this Section 4.16, the Trustee shall act as the Paying Agent. The Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.16, the Issuers shall comply with the applicable securities laws and regulations and shall not be deemed to have breached their obligations under the provisions of this Section 4.16 by virtue thereof. SECTION 4.17. Limitation on Preferred Stock of Restricted Subsidiaries. The Company will not cause or permit any of its Restricted Subsidiaries to issue any Preferred Stock (other than to the Company or to a Wholly Owned Restricted Subsidiary) or permit any Person (other than the Company or a Wholly Owned Restricted Subsidiary) to own any Preferred Stock of any Restricted Subsidiary. SECTION 4.18. Limitation on Liens. Other than Permitted Liens, the Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or permit or suffer to exist any Liens of any kind against or upon any property or assets of the Company or any of its Restricted Subsidiaries (whether owned on the Issue Date or acquired after the Issue Date) or any proceeds therefrom, or assign or otherwise convey any right to receive income or profits therefrom unless (a) in the case of Liens securing Indebtedness that is expressly subordinate or junior in right of payment to the Notes or any Guarantee, the Notes or such Guarantee, as the case may be, are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens at least to the same extent as the Notes are senior in priority to such Indebtedness and (b) in all other cases, the Notes and the Guarantees are equally and ratably secured. SECTION 4.19. Limitation on Conduct of Business. The Company will not, and will not permit any of its Restricted Subsidiaries to, engage in the conduct of any business other than the Crude Oil and Natural Gas Business. 57 145385.01 SECTION 4.20. Additional Subsidiary Guarantees. If the Company or any of its Restricted Subsidiaries transfers or causes to be transferred, in one transaction or a series of related transactions, any property to any Restricted Subsidiary that is not a Subsidiary Guarantor, or if the Company or any of its Restricted Subsidiaries shall organize, acquire or otherwise invest in or hold an Investment in another Restricted Subsidiary having total consolidated assets with a book value in excess of $500,000 that is not a Subsidiary Guarantor, then such transferee or acquired or other Restricted Subsidiary shall (a) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Company's obligations under the Notes and this Indenture on the terms set forth in this Indenture and (b) deliver to the Trustee an Opinion of Counsel and an Officers' Certificate, stating that no event of default shall occur as a result of such supplemental indenture, that it complies with the terms of this Indenture and that such supplemental indenture has been duly authorized, executed and delivered by such Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Restricted Subsidiary. Thereafter, such Restricted Subsidiary shall be a Subsidiary Guarantor for all purposes of the Indenture. 58 145385.01 ARTICLE FIVE SUCCESSOR CORPORATION SECTION 5.1. Merger, Consolidation and Sale of Assets. The Company will not, in a single transaction or series of related transactions, consolidate or merge with or into any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or cause or permit any Restricted Subsidiary to sell, assign, transfer, lease, convey or otherwise dispose of) all or substantially all of the Company's assets (determined on a consolidated basis for the Company and its Restricted Subsidiaries), whether as an entirety or substantially as an entirety to any Person unless: (a) either (i) the Company or such Restricted Subsidiary, as the case may be, shall be the surviving or continuing corporation or (ii) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by sale, assignment, transfer, lease, conveyance or other disposition the properties and assets of the Company and its Restricted Subsidiaries substantially as an entirety (the "Surviving Entity") (x) shall be a corporation organized and validly existing under the laws of the United States or any state thereof or the District of Columbia and (y) shall expressly assume, by supplemental indenture (in form and substance satisfactory to the Trustee), executed and delivered to the Trustee, the due and punctual payment of the principal of, premium, if any, and interest on all of the Notes and the performance of every covenant of the Notes, the Indenture and the Registration Rights Agreement on the part of the Company to be performed or observed; (b) immediately after giving effect to such transaction and the assumption contemplated by clause (a)(ii)(y) above (including giving effect to any Indebtedness incurred or anticipated to be incurred in connection with or in respect of such transaction), the Company or such Surviving Entity, as the case may be, (i) shall have a Consolidated Net Worth equal to or greater than the Consolidated Net Worth of the Company immediately prior to such transaction and (ii) shall be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.12 hereof; (c) immediately before and immediately after giving effect to such transaction and the assumption contemplated by clause (a)(ii)(y) above (including, without limitation, giving effect to any Indebtedness incurred or anticipated to be incurred and any Lien granted in connection with or in respect of the transaction), no Default or Event of Default shall have occurred or be continuing; and (d) the Company or the Surviving Entity, as the case may be, shall have delivered to the Trustee an officers' certificate and an opinion of counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture comply with the applicable provisions hereof and that all conditions precedent in this Indenture relating to such transaction have been satisfied; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Company. 59 145385.01 For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries the Capital Stock of which constitutes all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. Notwithstanding the foregoing, nothing in this Section shall prohibit the merger of CGGS with and into Canadian Abraxas. Each Subsidiary Guarantor (other than any Subsidiary Guarantor whose Guarantee is to be released in accordance with the terms of the Guarantee and this Indenture in connection with any transaction complying with the provisions of the Indenture described under Article Five) will not, and the Company will not cause or permit any Subsidiary Guarantor to, consolidate with or merge with or into any Person other than the Company or another Subsidiary Guarantor that is a Wholly Owned Restricted Subsidiary unless: (a) the entity formed by or surviving any such consolidation or merger (if other than the Subsidiary Guarantor) or to which such sale, lease, conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States or any state thereof or the District of Columbia; (b) such entity assumes by execution of a supplemental indenture all of the obligations of the Subsidiary Guarantor under its Guarantee; (c) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; and (d) immediately after giving effect to such transaction and the use of any net proceeds therefrom on a pro forma basis, the Company could satisfy the provisions of clause (b) of the first paragraph of this covenant. Any merger or consolidation of a Subsidiary Guarantor with and into the Company (with the Company being the surviving entity) or another Subsidiary Guarantor that is a Wholly Owned Restricted Subsidiary need only comply with clause (d) of the first paragraph of this Section 5.01. SECTION 5.02. Successor Corporation Substituted. Upon any consolidation, merger, conveyance, lease or transfer in accordance with Section 5.01, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, lease or transfer is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company herein and thereafter (except in the case of a lease) the predecessor corporation will be relieved of all further obligations and covenants under this Indenture and the Notes. 60 145385.01 ARTICLE SIX REMEDIES SECTION 6.01. Events of Default. An "Event of Default" means any of the following events: (a) the failure to pay interest (including any Additional Interest) on any Notes when the same becomes due and payable and such default continues for a period of 30 days; (b) the failure to pay the principal of any Notes when such principal becomes due and payable, at maturity, upon redemption or otherwise (including the failure to make a payment to purchase Notes tendered pursuant to a Change of Control Offer or a Net Proceeds Offer); (c) a default in the observance or performance of any other covenant or agreement contained in this Indenture which default continues for a period of 30 days after either Issuer or Subsidiary Guarantor receives written notice specifying the default (and demanding that such default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the Notes (except in the case of a default with respect to observance or performance of any of the terms or provisions of Section 4.15, 4.16 or 5.01 which will constitute an Event of Default with such notice requirement but without such passage of time requirement); (d) a default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness of the Company or any Restricted Subsidiary (or the payment of which is guaranteed by the Issuers or any Restricted Subsidiary), whether such Indebtedness now exists, or is created after the Issue Date, which default (i) is caused by a failure to pay principal of or premium, if any, or interest on such Indebtedness after any applicable grace period provided in such Indebtedness (a "Payment Default") or (ii) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $5,000,000 or more; (e) one or more judgments in an aggregate amount in excess of $5,000,000 (unless covered by insurance by a reputable insurer as to which the insurer has acknowledged coverage) shall have been rendered against the Company or any of its Restricted Subsidiaries and such judgments remain undischarged, unvacated, unpaid or unstayed for a period of 60 days after such 61 145385.01 judgment or judgments become final and non-appealable; (f) the Company or any of its Subsidiaries pursuant to or under or within the meaning of any Bankruptcy Law: (i) commences a voluntary case or proceeding; (ii) consents to the entry of an order for relief against it in an involuntary case or proceeding; (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property; (iv) makes a general assignment for the benefit of its creditors; or (v) shall generally not pay its debts when such debts become due or shall admit in writing its inability to pay its debts generally; (g) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Company or any Subsidiary of the Company in an involuntary case or proceeding, (ii) appoints a Custodian of the Company or any Subsidiary of the Company for all or substantially all of its Properties, or (iii) orders the liquidation of the Company or any Subsidiary of the Company, and in each case the order or decree remains unstayed and in effect for 60 days; or (h) any of the Guarantees cease to be in full force and effect or any of the Guarantees are declared to be null and void or invalid and unenforceable or any of the Subsidiary Guarantors denies or disaffirms its liability under its Guarantees (other than by reason of release of a Subsidiary Guarantor in accordance with the terms of this Indenture). 62 145385.01 SECTION 6.02. Acceleration. Upon the happening of any Event of Default specified in Section 6.01 the Trustee may, or the holders of at least 25% in aggregate principal amount of outstanding Notes may, declare the principal of, premium, if any, and accrued and unpaid interest on all the Notes to be due and payable by notice in writing to the Issuers and the Trustee specifying the respective Event of Default and that it is a "notice of acceleration" and the same shall become immediately due and payable. If an Event of Default of the type described in clause (f) or (g) above occurs and is continuing, then such amount will ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. At any time after a declaration of acceleration with respect to the Notes as described in the preceding paragraph, the Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Company and the Trustee may rescind and cancel such declaration and its consequences (a) if the rescission would not conflict with any judgment or decree, (b) if all existing Events of Default have been cured or waived except nonpayment of principal or interest that has become due solely because of such acceleration, (c) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid, (d) if the Issuers have paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances and (e) in the event of the cure or waiver of an Event of Default of the type described in clause (f) or (g) of the description of Events of Default above, the Trustee shall have received an Officers' Certificate and an Opinion of Counsel that such Event of Default has been cured or waived; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Company. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 63 145385.01 SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of, premium, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. All rights of action and claims under this Indenture or the Notes may be enforced by the Trustee even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. SECTION 6.04. Waiver of Past Defaults. Prior to the declaration of acceleration of the Notes, the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may, on behalf of the Holders of all the Notes, waive any existing Default or Event of Default and its consequences under this Indenture, except a Default or Event of Default specified in Section 6.01(a) or (b) or in respect of any provision hereof which cannot be modified or amended without the consent of the Holder so affected pursuant to Section 9.02. When a Default or Event of Default is so waived, it shall be deemed cured and shall cease to exist. This Section 6.04 shall be in lieu of ss. 316(a)(1)(B) of the TIA and such ss. 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. SECTION 6.05. Control by Majority. Holders of the Notes may not enforce this Indenture or the Notes except as provided in this Article Six and under the TIA. The Holders of not less than a majority in aggregate principal amount of the outstanding Notes shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided, however, that the Trustee may refuse to follow any direction (a) that conflicts with any rule of law or this Indenture, (b) that the Trustee determines may be unduly prejudicial to the rights of another Holder, or (c) that may expose the Trustee to personal liability for which reasonable indemnity provided to the Trustee against such liability shall be inadequate; provided, further, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction or this Indenture. This Section 6.05 shall be in lieu of ss. 316(a)(1)(A) of the TIA, and such ss. 316(a)(1)(A) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. 64 145385.01 SECTION 6.06. Limitation on Suits. No Holder of any Notes shall have any right to institute any proceeding with respect to this Indenture or the Notes or any remedy hereunder, unless the Holders of at least 25% in aggregate principal amount of the outstanding Notes have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as Trustee under the Notes and this Indenture, the Trustee has failed to institute such proceeding within 30 days after receipt of such notice, request and offer of indemnity and the Trustee, within such 30-day period, has not received directions inconsistent with such written request by Holders of not less than a majority in aggregate principal amount of the outstanding Notes. The foregoing limitations shall not apply to a suit instituted by a Holder of a Note for the enforcement of the payment of the principal of, premium, if any, or interest on, such Note on or after the respective due dates expressed or provided for in such Note. A Holder may not use this Indenture to prejudice the rights of any other Holders or to obtain priority or preference over such other Holders. SECTION 6.07. Right of Holders To Receive Payment. Notwithstanding any other provision in this Indenture, the right of any Holder of a Note to receive payment of the principal of, premium, if any, and interest on such Note, on or after the respective due dates expressed or provided for in such Note, or to bring suit for the enforcement of any such payment on or after the respective due dates, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder. SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company, or any other obligor on the Notes for the whole amount of the principal of, premium, if any, and accrued interest remaining unpaid, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, in each case at the rate per annum provided for by the Notes and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 65 145385.01 SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents, counsel, accountants and experts) and the Holders allowed in any judicial proceedings relative to the Issuers or Restricted Subsidiaries (or any other obligor upon the Notes), their creditors or their property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such judicial proceedings is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee under Section 7.07. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10 Priorities. If the Trustee collects any money pursuant to this Article Six it shall pay out such money in the following order: First: to the Trustee for amounts due under Section 7.07; Second: to Holders for interest accrued on the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for interest; Third: to Holders for the principal amounts (including any premium) owing under the Notes, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for the principal (including any premium); and Fourth: the balance, if any, to the Issuers. The Trustee, upon prior written notice to the Issuers, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. 66 145385.01 SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court may in its discretion require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to any suit by the Trustee, any suit by a Holder pursuant to Section 6.06, or a suit by a Holder or Holders of more than 10% in aggregate principal amount of the outstanding Notes. SECTION 6.12. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture or any Note and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Issuers, the Trustee and the Holders shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. ARTICLE SEVEN TRUSTEE SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise thereof as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. (b) Except during the continuance of an Event of Default: (1) The Trustee need perform only those duties as are specifically set forth in this Indenture and no covenants or obligations shall be implied in this Indenture that are adverse to the Trustee. (2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or 67 145385.01 opinions that by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (c) Notwithstanding anything to the contrary herein contained, the Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (1) This paragraph does not limit the effect of paragraph (b) of this Section 7.01. (2) The Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. (3) The Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.02, 6.04 or 6.05. (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (e) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), (c) and (d) of this Section 7.01 and Section 7.02. (f) The Trustee shall not be liable for interest on any money or assets received by it except as the Trustee may agree in writing with the Issuers. Assets held in trust by the Trustee need not be segregated from other assets except to the extent required by law. SECTION 7.02. Rights of Trustee. Subject to Section 7.01: (a) The Trustee may rely and shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper Person.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred by it in compliance with such request, order or direction. (g) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers, any of their Subsidiaries, or their respective Affiliates with the same rights it would have if it were not Trustee.

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Notes, and it shall not be accountable for the Issuers' use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuers in this Indenture or the Notes other than the Trustee's certificate of authentication.

The foregoing sentence of this Section 7.05 shall be in lieu of the proviso to ss. 315(b) of the TIA and such proviso to ss. 315(b) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA.

The Issuers shall promptly notify the Trustee if the Notes become listed on any stock exchange and the Trustee shall comply with TIA ss. 313(d). 70 145385.01 SECTION 7.07. Compensation and Indemnity. The Issuers shall pay to the Trustee from time to time such compensation for its services as has been agreed to in writing signed by the Issuers and the Trustee. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuers shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it in connection with the performance of its duties under this Indenture. Such expenses shall include the reasonable fees and expenses of the Trustee's agents, counsel, accountants and experts. The Issuers shall indemnify each of the Trustee (or any predecessor Trustee) and its agents, employees, stockholders, Affiliates and directors and officers for, and hold them each harmless against, any and all loss, liability, damage, claim or expense (including reasonable fees and expenses of counsel), including taxes (other than taxes based on the income of the Trustee) incurred by them except for such actions to the extent caused by any negligence, bad faith or willful misconduct on their part, arising out of or in connection with the acceptance or administration of this trust including the reasonable costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their rights, powers or duties hereunder. The Trustee shall notify the Issuers promptly of any claim asserted against the Trustee for which it may seek indemnity. At the Trustee's sole discretion, the Issuers shall defend the claim and the Trustee shall cooperate and may participate in the defense; provided, however, that any settlement of a claim shall be approved in writing by the Trustee if such settlement would result in an admission of liability by the Trustee or if such settlement would not be accompanied by a full release of the Trustee for all liability arising out of the events giving rise to such claim. Alternatively, the Trustee may at its option have separate counsel of its own choosing and the Issuers shall pay the reasonable fees and expenses of such counsel. To secure the Issuers' payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Notes on all assets or money held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of or premium, if any, or interest on particular Notes. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(f) or (g) occurs, such expenses and the compensation for such services are intended to constitute expenses of administration under any Bankruptcy Law. The provisions of this Section 7.07 shall survive the termination of this Indenture. 71 145385.01 SECTION 7.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Issuers. The Holders of a majority in principal amount of the outstanding Notes may remove the Trustee and appoint a successor Trustee with the Issuers' consent, by so notifying the Issuers and the Trustee. The Issuers may remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; (2) the Trustee is adjudged bankrupt or insolvent; (3) a receiver or other public officer takes charge of the Trustee or its property; or (4) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers shall notify each Holder of such event and shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Immediately after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.07, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The Issuers shall mail notice of such successor Trustee's appointment to each Holder. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuers or the Holders of at least 10% in aggregate principal amount of the outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Notwithstanding any resignation or replacement of the Trustee pursuant to this Section 7.08, the Issuers' obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 72 145385.01 SECTION 7.09. Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee; provided, however, that such corporation shall be otherwise qualified and eligible under this Article Seven. SECTION 7.10 Eligibility; Disqualification. This Indenture shall always have a Trustee who satisfies the requirement of TIA ss.ss. 310(a)(1), (2) and (5). The Trustee (or, in the case of a Trustee that is a corporation included in a bank holding company system, the related bank holding company) shall have a combined capital and surplus of at least $150 million as set forth in its most recent published annual report of condition, and have a Corporate Trust Office in the City of New York. In addition, if the Trustee is a corporation included in a bank holding company system, the Trustee, independently of such bank holding company, shall meet the capital requirements of TIA ss. 310(a)(2). The Trustee shall comply with TIA ss. 310(b); provided, however, that there shall be excluded from the operation of TIA ss. 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuers are outstanding, if the requirements for such exclusion set forth in TIA ss. 310(b)(1) are met. The provisions of TIA ss. 310 shall apply to the Company, as obligors of the Notes. SECTION 7.11 Preferential Collection of Claims Against Issuers. The Trustee shall comply with TIA ss. 311(a), excluding any creditor relationship listed in TIA ss. 311(b). A Trustee who has resigned or been removed shall be subject to TIA ss. 311(a) to the extent indicated therein. The provisions of TIA ss. 311 shall apply to the Issuers, as obligors on the Notes. 73 145385.01 ARTICLE EIGHT DISCHARGE OF INDENTURE; DEFEASANCE SECTION 8.01 Termination of Issuers' Obligations. This Indenture will be discharged and will cease to be of further effect (except as to surviving rights of registration of transfer or exchange of the Notes, as expressly provided for in this Indenture) as to all outstanding Notes when (a) either (i) all Notes, theretofore authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from such trust) have been delivered to the Trustee for cancellation or (ii) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable and the Issuers have irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the Notes to the date of deposit together with irrevocable instructions from the Issuers directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be; (b) the Issuers have paid all other sums payable under this Indenture by the Issuers; and (c) the Issuers have delivered to the Trustee an officers' certificate and an opinion of counsel stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture have been complied with; provided, however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuers. The Issuers may, at their option and at any time, elect to have their obligations and the corresponding obligations of the Subsidiary Guarantors discharged with respect to the outstanding Notes ("Legal Defeasance"). Such Legal Defeasance means that the Issuers shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, and satisfied all of their obligations with respect to the Notes, except for (a) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due, (b) the Issuers' obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payments, (c) the rights, powers, trust, duties and immunities of the Trustee and the Issuers' obligations in connection therewith and (d) the Legal Defeasance provisions of this Section 8.01. In addition, the Issuers may, at their option and at any time, elect to have the obligations of the Issuers and the Subsidiary Guarantors, if any, released with respect to covenants contained in Sections 4.04, 4.08 and 4.10 through 4.20 and Article Five ("Covenant Defeasance") and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes. In the event of Covenant Defeasance, those events described under Section 6.01 (except those events described in Section 6.01(a),(b),(f) and (g)) will no longer constitute an Event of Default with respect to the Notes. 74 145385.01 75 145385.01 In order to exercise either Legal Defeasance or Covenant Defeasance: (a) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in United States dollars, non-callable U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be; (b) in the case of Legal Defeasance, the Issuers shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that (i) the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of this Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (c) in the case of Covenant Defeasance, the Issuers shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that the Holders will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or insofar as Events of Default under Section 6.01(f) or (g) from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; (e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under this Indenture or any other agreement or instrument to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; (f) the Issuers shall have delivered to the Trustee an officers' certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders over any other creditors of either Issuer or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Issuers or others; (g) the Issuers shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with; provided, 76 145385.01 however, that such counsel may rely, as to matters of fact, on a certificate or certificates of officers of the Issuers; (h) the Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally; and (i) certain other customary conditions precedent are satisfied. SECTION 8.02. Application of Trust Money. The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or U.S. Government Obligations deposited with it pursuant to Section 8.01, and shall apply the deposited U.S. Legal Tender and the money from U.S. Government Obligations in accordance with this Indenture to the payment of the principal of and interest on the Notes. The Trustee shall be under no obligation to invest said U.S. Legal Tender or U.S. Government Obligations except as it may agree in writing with the Issuers. The Issuers shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Legal Tender or U.S. Government Obligations deposited pursuant to Section 8.01 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of outstanding Notes. SECTION 8.03. Repayment to the Issuers. Subject to Section 8.01, the Trustee and the Paying Agent shall promptly pay to the Issuers upon request any excess U.S. Legal Tender or U.S. Government Obligations held by them at any time and thereupon shall be relieved from all liability with respect to such money. The Trustee and the Paying Agent shall pay to the Issuers upon request any money held by them for the payment of principal or interest that remains unclaimed for one year; provided, however, that the Trustee or such Paying Agent, before being required to make any payment, may at the expense of the Issuers cause to be published once in a newspaper of general circulation in the City of New York or mail to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein which shall be at least 30 days from the date of such publication or mailing any unclaimed balance of such money then remaining will be repaid to the Issuers. After payment to the Issuers, Holders entitled to such money must look to the Issuers for payment as general creditors unless an applicable law designates another Person. 77 145385.01 SECTION 8.04. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuers' obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or Paying Agent is permitted to apply all such U.S. Legal Tender or U.S. Government Obligations in accordance with Section 8.01; provided, however, that if the Issuers have made any payment of interest on or principal of any Notes because of the reinstatement of their obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the U.S. Legal Tender or U.S. Government Obligations held by the Trustee or Paying Agent. SECTION 8.05. Acknowledgment of Discharge by Trustee. After (i) the conditions of Section 8.01 have been satisfied, (ii) the Issuers have paid or caused to be paid all other sums payable hereunder by the Issuers and (iii) each of the Issuers has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent referred to in clause (i) above relating to the satisfaction and discharge of this Indenture have been complied with, the Trustee upon request shall acknowledge in writing the discharge of the Issuers' obligations under this Indenture except for those surviving obligations specified in Section 8.01, provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers' Certificates of the Issuers. 78 145385.01 ARTICLE NINE MODIFICATION OF THE INDENTURE SECTION 9.01. Without Consent of Holders. Subject to the provisions of Section 9.02, the Issuers, the Subsidiary Guarantors and the Trustee may amend, waive or supplement this Indenture without notice to or consent of any Holder: (a) to cure any ambiguity, defect or inconsistency; (b) to comply with Section 5.01 of this Indenture; (c) to provide for uncertificated Notes in addition to certificated Notes; (d) to comply with any requirements of the Commission in order to effect or maintain the qualification of this Indenture under the TIA; or (e) to make any change that would provide any additional benefit or rights to the Holders or that does not adversely affect the rights of any Holder. Notwithstanding the foregoing, the Trustee and the Issuers may not make any change that adversely affects the rights of any Holder under this Indenture without the consent of such Holder. In formulating its opinion on such matters, the Trustee will be entitled to rely on such evidence as it deems appropriate, including, without limitation, solely on an Opinion of Counsel; provided, however, that in delivering such Opinion of Counsel, such counsel may rely as to matters of fact, on a certificate or certificates of officers of the Company. SECTION 9.02. With Consent of Holders. All other modifications and amendments of this Indenture may be made with the consent of the Holders of a majority in the then outstanding principal amount of the then outstanding Notes, except that, without the consent of each Holder of the Notes affected thereby, no amendment may, directly or indirectly: (i) reduce the amount of Notes whose Holders must consent to any amendment; (ii) reduce the rate of or change the time for payment of interest, including defaulted interest, on any Notes; (iii) reduce the principal of or change the fixed maturity of any Notes, or change the date on which any Notes may be subject to redemption or repurchase, or reduce the redemption or repurchase price therefor; (iv) make any Notes payable in money other than that stated in the Notes; (v) make any change in provisions of this Indenture protecting the right of each Holder of a Note to receive payment of principal of and interest on such Note on or after the due date thereof or to bring suit to enforce such payment or permitting Holders of a majority in aggregate principal amount of the then outstanding Notes to waive Defaults or Events of Default; (vi) amend, change or modify in any material respect the obligation of the Issuers to make and consummate a Change of Control Offer in the event of a Change of Control or make and consummate a Net Proceeds Offer with respect to any Asset Sale that has been consummated or modify any of the provisions or definitions with respect thereto; (vii) modify or change any provision of this Indenture or Section 1.01 affecting the ranking of the Notes or any Guarantee in a manner which adversely affects the Holders; or (viii) release any Subsidiary Guarantor from any of its obligations under its Guarantee or this Indenture otherwise than in accordance with the terms of this Indenture. 79 145385.01 SECTION 9.03. Compliance with TIA. Every amendment, waiver or supplement of this Indenture or the Notes shall comply with the TIA as then in effect; provided, however, that this Section 9.03 shall not of itself require that this Indenture or the Trustee be qualified under the TIA or constitute any admission or acknowledgment by any party hereto that any such qualification is required prior to the time this Indenture and the Trustee are required by the TIA to be so qualified. SECTION 9.04. Revocation and Effect of Consents. Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of such Note by notice to the Trustee or the Issuers received before the date on which the Trustee receives an Officers' Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. An amendment, supplement or waiver becomes effective upon receipt by the Trustee of such Officers' Certificate and evidence of consent by the Holders of the requisite percentage in principal amount of outstanding Notes. The Issuers may, but shall not be obligated to, fix a Record Date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which Record Date shall be at least 30 days prior to the first solicitation of such consent. If a Record Date is fixed, then notwithstanding the second sentence of the immediately preceding paragraph, those Persons who were Holders at such Record Date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such Record Date. No such consent shall be valid or effective for more than 90 days after such Record Date unless consents from Holders of the requisite percentage in principal amount of outstanding Notes required hereunder for the effectiveness of such consents shall have also been given and not revoked within such 90 day period. SECTION 9.05. Notation on or Exchange of Notes. If an amendment, supplement or waiver changes the terms of a Note, the Trustee may require the Holder of such Note to deliver it to the Trustee. The Trustee may place an appropriate notation on the Note about the changed terms and return it to the Holder. Alternatively, if the Issuers or the Trustee so determine, the Issuers in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. 80 145385.01 SECTION 9.06. Trustee To Sign Amendments, Etc. The Trustee shall execute any amendment, supplement or waiver authorized pursuant to this Article Nine; provided, however, that the Trustee may, but shall not be obligated to, execute any such amendment, supplement or waiver which affects the Trustee's own rights, duties or immunities under this Indenture. In executing such supplement or waiver the Trustee shall be entitled to receive indemnity reasonably satisfactory to it, and shall be fully protected in relying upon an Opinion of Counsel and an Officers' Certificate of each Issuer, each stating that no event of default shall occur as a result of such amendment, supplement or waiver and that the execution of any amendment, supplement or waiver authorized pursuant to this Article Nine is authorized or permitted by this Indenture, provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers' Certificates of the Issuers. Such Opinion of Counsel shall not be an expense of the Trustee. ARTICLE TEN MISCELLANEOUS SECTION 10.01. TIA Controls. If any provision of this Indenture limits, qualifies, or conflicts with another provision which is required to be included in this Indenture by the TIA, the required provision shall control; provided, however, that this Section 10.01 shall not of itself require that this Indenture or the Trustee be qualified under the TIA or constitute any admission or acknowledgment by any party hereto that any such qualification is required prior to the time this Indenture and the Trustee are required by the TIA to be so qualified.

Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture, other than the Officers' Certificate required by Section 4.06, shall include: (1) a statement that the Person making such certificate or opinion has read such covenant or condition; (2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; (3) a statement that, in the opinion of such Person, he has made such examination or investigation as is reasonably necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and (4) a statement as to whether or not, in the opinion of each such Person, such condition or covenant has been complied with. SECTION 10.06. Rules by Trustee, Paying Agent, Registrar. The Trustee may make reasonable rules in accordance with the Trustee's customary practices for action by or at a meeting of Holders. The Paying Agent or Registrar may make reasonable rules for its functions. 83 145385.01 SECTION 10.07. Legal Holidays.

SECTION 10.08. Governing Law. THIS INDENTURE AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS. Each of the parties hereto agrees to submit to the jurisdiction of the courts of the State of New York in any action or proceeding arising out of or relating to this Indenture. SECTION 10.09. No Adverse Interpretation of Other Agreements. This Indenture may not be used to interpret another indenture, loan or debt agreement of either Issuer or any of their Subsidiaries. Any such indenture, loan or debt agreement may not be used to interpret this Indenture. SECTION 10.10. No Personal Liability. No director, officer, employee or stockholder, as such, of either Issuer or any Subsidiary Guarantor, as such, shall have any liability for any obligations of either Issuer or any Subsidiary Guarantor under the Notes, this Indenture, the Guarantees or the Registration Rights Agreement or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. SECTION 10.11. Successors. All agreements of the Issuers in this Indenture and the Notes shall bind their successors. All agreements of the Trustee in this Indenture shall bind its successors. SECTION 10.12.

Unconditional Guarantee. Subject to the provisions of this Article Eleven, each Subsidiary Guarantor, if any, hereby, jointly and severally, unconditionally and irrevocably guarantees, on a senior basis (such guarantee to be referred to herein as a "Guarantee") to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuers or any other Subsidiary Guarantors to the Holders or the Trustee hereunder or thereunder, that: (a) the principal of, premium, if any, and interest on the Notes (and any Additional Interest payable thereon) shall be duly and punctually paid in full when due, whether at maturity, upon redemption at the option of Holders pursuant to the provisions of the Notes relating thereto, by acceleration or otherwise, and interest on the overdue principal and (to the extent permitted by law) interest, if any, on the Notes and all other obligations of the Issuers or the Subsidiary Guarantors to the Holders or the Trustee hereunder or thereunder (including amounts due the Trustee under Section 7.07 hereof) and all other obligations shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed, or failing performance of any other obligation of the Issuers to the Holders under this Indenture or under the Notes, for whatever reason, each Subsidiary Guarantor shall be obligated to pay, or to perform or cause the performance of, the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under this Guarantee, and shall entitle the Holders of Notes to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the obligations of the Issuers. Each of the Subsidiary Guarantors hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, any release of any other Subsidiary Guarantor, the recovery of any judgment against the Issuers, any action to enforce the same, whether or not a Guarantee is affixed to any particular Note, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each of the Subsidiary Guarantors hereby waives the benefit of diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that its Guarantee shall not be discharged except by complete performance of 86 145385.01 the obligations contained in the Notes, this Indenture and this Guarantee. This Guarantee is a guarantee of payment and not of collection. If any Holder or the Trustee is required by any court or otherwise to return to the Issuers or to any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuers or such Subsidiary Guarantor, any amount paid by the Issuers or such Subsidiary Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor further agrees that, as between it, on the one hand, and the Holders of Notes and the Trustee, on the other hand, (a) subject to this Article Eleven, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (b) in the event of any acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of this Guarantee. No stockholder, officer, director, employee or incorporator, past, present or future, or any Subsidiary Guarantor, as such, shall have any personal liability under this Guarantee by reason of his, her or its status as such stockholder, officer, director, employee or incorporator. Each Subsidiary Guarantor that makes a payment or distribution under its Guarantee shall be entitled to a contribution from each other Subsidiary Guarantor, determined in accordance with GAAP. SECTION 11.02. Limitations on Guarantees. The obligations of each Subsidiary Guarantor under its Guarantee will be limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, will result in the obligations of such Subsidiary Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. SECTION 11.03. Execution and Delivery of Guarantee. To further evidence the Guarantee set forth in Section 11.01, each Subsidiary Guarantor hereby agrees that a notation of such Guarantee, substantially in the form of Exhibit E herein, shall be endorsed on each Note authenticated and delivered by the Trustee. Such Guarantee shall be executed on behalf of each Subsidiary Guarantor by either manual or facsimile signature of two Officers of each Subsidiary Guarantor, each of whom, in each case, shall have been duly authorized to so execute by all requisite corporate action. The validity and enforceability of any Guarantee shall not be affected by the fact that it is not affixed to any particular Note. 87 145385.01 Each of the Subsidiary Guarantors hereby agrees that its Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee. If an Officer of a Subsidiary Guarantor whose signature is on this Indenture or a Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such Guarantee is endorsed or at any time thereafter, such Subsidiary Guarantor's Guarantee of such Note shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of each Subsidiary Guarantor. SECTION 11.04. Release of a Subsidiary Guarantor. (a) If no Default exists or would exist under this Indenture, upon the sale or disposition of all of the Capital Stock of a Subsidiary Guarantor by the Issuers or a Restricted Subsidiary of the Issuers in a transaction constituting an Asset Sale the Net Cash Proceeds of which are applied in accordance with Section 4.16, or upon the consolidation or merger of a Subsidiary Guarantor with or into any Person in compliance with Article Five (in each case, other than to an Issuer or an Affiliate of an Issuer or a Restricted Subsidiary), such Subsidiary Guarantor and each Subsidiary of such Subsidiary Guarantor that is also a Subsidiary Guarantor shall be deemed released from all obligations under this Article Eleven without any further action required on the part of the Trustee or any Holder; provided, however, that each such Subsidiary Guarantor is sold or disposed of in accordance with this Indenture. Any Subsidiary Guarantor not so released or the entity surviving such Subsidiary Guarantor, as applicable, shall remain or be liable under its Guarantee as provided in this Article Eleven. (b) The Trustee shall deliver an appropriate instrument evidencing the release of a Subsidiary Guarantor upon receipt of a request by the Issuers or such Subsidiary Guarantor accompanied by an Officers' Certificate and an Opinion of Counsel certifying as to the compliance with this Section 11.04, provided the legal counsel delivering such Opinion of Counsel may rely as to matters of fact on one or more Officers Certificates of the Issuers. The Trustee shall execute any documents reasonably requested by the Issuers or a Subsidiary Guarantor in order to evidence the release of such Subsidiary Guarantor from its obligations under its Guarantee endorsed on the Notes and under this Article Eleven. Except as set forth in Articles Four and Five and this Section 11.04, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Subsidiary Guarantor with or into the Issuers or another Subsidiary Guarantor or shall prevent any sale or conveyance of the property of a Subsidiary Guarantor as an entirety or substantially as an entirety to the Issuers or another Subsidiary Guarantor. 88 145385.01 SECTION 11.05. Waiver of Subrogation. Until this Indenture is discharged and all of the Notes are discharged and paid in full, each Subsidiary Guarantor hereby irrevocably waives and agrees not to exercise any claim or other rights which it may now or hereafter acquire against the Issuers that arise from the existence, payment, performance or enforcement of the Issuers' obligations under the Notes or this Indenture and such Subsidiary Guarantor's obligations under this Guarantee and this Indenture, in any such instance including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, indemnification, and any right to participate in any claim or remedy of the Holders against the Issuers, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuers, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Subsidiary Guarantor in violation of the preceding sentence and any amounts owing to the Trustee or the Holders of Notes under the Notes, this Indenture, or any other document or instrument delivered under or in connection with such agreements or instruments, shall not have been paid in full, such amount shall have been deemed to have been paid to such Subsidiary Guarantor for the benefit of, and held in trust for the benefit of, the Trustee or the Holders and shall forthwith be paid to the Trustee for the benefit of itself or such Holders to be credited and applied to the obligations in favor of the Trustee or the Holders, as the case may be, whether matured or unmatured, in accordance with the terms of this Indenture. Each Subsidiary Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 11.05 is knowingly made in contemplation of such benefits. SECTION 11.06. Immediate Payment. Each Subsidiary Guarantor agrees to make immediate payment to the Trustee on behalf of the Holders of all Obligations owing or payable to the respective Holders upon receipt of a demand for payment therefor by the Trustee to such Subsidiary Guarantor in writing. SECTION 11.07. No Set-Off. Each payment to be made by a Subsidiary Guarantor hereunder in respect of the Obligations shall be payable in the currency or currencies in which such Obligations are denominated, and shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 89 145385.01 SECTION 11.08. Obligations Absolute. The obligations of each Subsidiary Guarantor hereunder are and shall be absolute and unconditional and any monies or amounts expressed to be owing or payable by each Subsidiary Guarantor hereunder which may not be recoverable from such Subsidiary Guarantor on the basis of a Guarantee shall be recoverable from such Subsidiary Guarantor as a primary obligor and principal debtor in respect thereof. SECTION 11.09. Obligations Continuing. The obligations of each Subsidiary Guarantor hereunder shall be continuing and shall remain in full force and effect until all the obligations have been paid and satisfied in full. Each Subsidiary Guarantor agrees with the Trustee that it will from time to time deliver to the Trustee suitable acknowledgments of this continued liability hereunder and under any other instrument or instruments in such form as counsel to the Trustee may advise and as will prevent any action brought against it in respect of any default hereunder being barred by any statute of limitations now or hereafter in force and, in the event of the failure of a Subsidiary Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and agent of such Subsidiary Guarantor to make, execute and deliver such written acknowledgment or acknowledgments or other instruments as may from time to time become necessary or advisable, in the judgment of the Trustee on the advice of counsel, to fully maintain and keep in force the liability of such Subsidiary Guarantor hereunder. SECTION 11.10. Obligations Not Reduced. The obligations of each Subsidiary Guarantor hereunder shall not be satisfied, reduced or discharged solely by the payment of such principal, premium, if any, interest, fees and other monies or amounts as may at any time prior to discharge of this Indenture pursuant to Article 8 be or become owing or payable under or by virtue of or otherwise in connection with the Notes or this Indenture. SECTION 11.11. Obligations Reinstated. The obligations of each Subsidiary Guarantor hereunder shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment which would otherwise have reduced the obligations of any Subsidiary Guarantor hereunder (whether such payment shall have been made by or on behalf of the Issuers or by or on behalf of a Subsidiary Guarantor) is rescinded or reclaimed from any of the Holders upon the insolvency, bankruptcy, liquidation or reorganization of either Issuer or any Subsidiary Guarantor or otherwise, all as though such payment had not been made. If demand for, or acceleration of the time for, payment by the Issuers is stayed upon the insolvency, bankruptcy, liquidation or reorganization of either Issuer, all such Indebtedness otherwise subject to demand for payment or acceleration shall nonetheless be payable by each Subsidiary Guarantor as provided herein. 90 145385.01 SECTION 11.12. Obligations Not Affected. The obligations of each Subsidiary Guarantor hereunder shall not be affected, impaired or diminished in any way by any act, omission, matter or thing whatsoever, occurring before, upon or after any demand for payment hereunder (and whether or not known or consented to by any Subsidiary Guarantor or any of the Holders) which, but for this provision, might constitute a whole or partial defense to a claim against any Subsidiary Guarantor hereunder or might operate to release or otherwise exonerate any Subsidiary Guarantor from any of its obligations hereunder or otherwise affect such obligations, whether occasioned by default of any of the Holders or otherwise, including, without limitation: (a) any limitation of status or power, disability, incapacity or other circumstance relating to either Issuer or any other person, including any insolvency, bankruptcy, liquidation, reorganization, readjustment, composition, dissolution, winding-up or other proceeding involving or affecting either Issuer or any other person; (b) any irregularity, defect, unenforceability or invalidity in respect of any indebtedness or other obligation of either Issuer or any other person under this Indenture, the Notes or any other document or instrument; (c) any failure of the Issuers, whether or not without fault on their part, to perform or comply with any of the provisions of this Indenture or the Notes, or to give notice thereof to a Subsidiary Guarantor; (d) the taking or enforcing or exercising or the refusal or neglect to take or enforce or exercise any right or remedy from or against the Issuers or any other person or their respective assets or the release or discharge of any such right or remedy; (e) the granting of time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the Issuers or any other Person; (f) any change in the time, manner or place of payment of, or in any other term of, any of the Notes, or any other amendment, variation, supplement, replacement or waiver of, or any consent to departure from, any of the Notes or this Indenture, including, without limitation, any increase or decrease in the principal amount of or premium, if any, or interest on any of the Notes; (g) any change in the ownership, control, name, objects, businesses, assets, capital structure or constitution of either Issuer or a Subsidiary Guarantor; (h) any merger or amalgamation of either Issuer or a Subsidiary 91 145385.01 Guarantor with any Person or Persons; (i) the occurrence of any change in the laws, rules, regulations or ordinances of any jurisdiction by any present or future action of any governmental authority or court amending, varying, reducing or otherwise affecting, or purporting to amend, vary, reduce or otherwise affect, any of the Obligations or the obligations of a Subsidiary Guarantor under its Guarantee; and (j) any other circumstance, including release of the Subsidiary Guarantor pursuant to Section 11.04 (other than by complete, irrevocable payment) that might otherwise constitute a legal or equitable discharge or defense of the Issuers under this Indenture or the Notes or of a Subsidiary Guarantor in respect of its Guarantee hereunder. SECTION 11.13. Waiver. Without in any way limiting the provisions of Section 11.01 hereof, each Subsidiary Guarantor hereby waives notice of acceptance hereof, notice of any liability of any Subsidiary Guarantor hereunder, notice or proof of reliance by the Holders upon the obligations of any Subsidiary Guarantor hereunder, and diligence, presentment, demand for payment on the Issuers, protest, notice of dishonor or non-payment of any of the Obligations, or other notice or formalities to the Issuers or any Subsidiary Guarantor of any kind whatsoever. SECTION 11.14. No Obligation To Take Action Against the Issuers. Neither the Trustee nor any other Person shall have any obligation to enforce or exhaust any rights or remedies or to take any other steps under any security for the Obligations or against the Issuers or any other Person or any Property of the Issuers or any other Person before the Trustee is entitled to demand payment and performance by any or all Subsidiary Guarantors of their liabilities and obligations under their Guarantees or under this Indenture. SECTION 11.15. Dealing with the Issuers and Others. The Holders, without releasing, discharging, limiting or otherwise affecting in whole or in part the obligations and liabilities of any Subsidiary Guarantor hereunder and without the consent of or notice to any Subsidiary Guarantor, may (a) grant time, renewals, extensions, compromises, concessions, waivers, releases, discharges and other indulgences to the Issuers or any other Person; (b) take or abstain from taking security or collateral from the Issuers or from perfecting security or collateral of the Issuers; 92 145385.01 (c) release, discharge, compromise, realize, enforce or otherwise deal with or do any act or thing in respect of (with or without consideration) any and all collateral, mortgages or other security given by the Issuers or any third party with respect to the obligations or matters contemplated by this Indenture or the Notes; (d) accept compromises or arrangements from the Issuers; (e) apply all monies at any time received from the Issuers or from any security upon such part of the Obligations as the Holders may see fit or change any such application in whole or in part from time to time as the Holders may see fit; and (f) otherwise deal with, or waive or modify their right to deal with, the Issuers and all other Persons and any security as the Holders or the Trustee may see fit. SECTION 11.16. Default and Enforcement. If any Subsidiary Guarantor fails to pay in accordance with Section 11.06 hereof, the Trustee may proceed in its name as trustee hereunder in the enforcement of the Guarantee of any such Subsidiary Guarantor and such Subsidiary Guarantor's obligations thereunder and hereunder by any remedy provided by law, whether by legal proceedings or otherwise, and to recover from such Subsidiary Guarantor the obligations. SECTION 11.17. Amendment, Etc. No amendment, modification or waiver of any provision of this Indenture relating to any Subsidiary Guarantor or consent to any departure by any Subsidiary Guarantor or any other Person from any such provision will in any event be effective unless it is signed by such Subsidiary Guarantor and the Trustee. SECTION 11.18. Acknowledgment. Each Subsidiary Guarantor hereby acknowledges communication of the terms of this Indenture and the Notes and consents to and approves of the same. SECTION 11.19. Costs and Expenses. Each Subsidiary Guarantor shall pay on demand by the Trustee any and all costs, fees and expenses (including, without limitation, legal fees on a solicitor and client basis) incurred by the Trustee, its agents, advisors and counsel or any of the Holders in enforcing any of their rights under any Guarantee. 93 145385.01 SECTION 11.20. No Merger or Waiver; Cumulative Remedies. No Guarantee shall operate by way of merger of any of the obligations of a Subsidiary Guarantor under any other agreement, including, without limitation, this Indenture. No failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, remedy, power or privilege hereunder or under the Indenture or the Notes, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or under this Indenture or the Notes preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges in the Guarantee and under this Indenture, the Notes and any other document or instrument between a Subsidiary Guarantor and/or either Issuer and the Trustee are cumulative and not exclusive of any rights, remedies, powers and privilege provided by law. SECTION 11.21. Survival of Obligations. Without prejudice to the survival of any of the other obligations of each Subsidiary Guarantor hereunder, the obligations of each Subsidiary Guarantor under Section 11.01 shall survive the payment in full of the Obligations and shall be enforceable against such Subsidiary Guarantor without regard to and without giving effect to any defense, right of offset or counterclaim available to or which may be asserted by the Company or any Subsidiary Guarantor. SECTION 11.22. Guarantee in Addition to Other Obligations. The obligations of each Subsidiary Guarantor under its Guarantee and this Indenture are in addition to and not in substitution for any other obligations to the Trustee or to any of the Holders in relation to this Indenture or the Notes and any guarantees or security at any time held by or for the benefit of any of them. SECTION 11.23. Severability. Any provision of this Article Eleven which is prohibited or unenforceable in any jurisdiction shall not invalidate the remaining provisions and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction unless its removal would substantially defeat the basic intent, spirit and purpose of this Indenture and this Article Eleven. 94 145385.01 SECTION 11.24. Successors and Assigns. Each Guarantee shall be binding upon and inure to the benefit of each Subsidiary Guarantor and the Trustee and the other Holders and their respective successors and permitted assigns, except that no Subsidiary Guarantor may assign any of its obligations hereunder or thereunder.

The Issuers issued the Notes under an Indenture, dated as of November 14, 1996 (the "Indenture"), among the Issuers, the Subsidiary Guarantors and the Trustee. This Note is one of a duly authorized issue of Initial Notes of the Issuers designated as their 11 1/2% Senior Notes due 2004, Series A (the "Initial Notes"). The Notes are limited in aggregate principal amount to $215,000,000. The Notes include the Initial Notes and the Exchange Notes, as defined below, issued in exchange for the Initial Notes pursuant to the Registration Rights Agreement. The Initial Notes and the Exchange Notes are treated as a single class of securities under the Indenture. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code ss.ss. 77aaa-77bbbb) (the "TIA"), as in effect 145385.01 on the date of the Indenture. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and said Act for a statement of them. The Notes are general unsecured obligations of the Issuers. 5. Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time in accordance with its terms. 6. Redemption.

In order to effect the foregoing redemption with the proceeds of any Equity Offering, the Issuers shall make such redemption not more than 60 days after the consummation of any Equity Offering. 7. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder's registered address. Notes in denominations larger than $1,000 may be redeemed in part. Except as set forth in the Indenture, if monies for the redemption of the Notes called for redemption shall have been deposited with the Paying Agent for redemption on such Redemption Date, then, unless the Issuers default in the payment of such Redemption Price plus accrued interest, if any, the Notes called for redemption will cease to bear interest from and after such Redemption Date and the only right of the Holders of such Notes will be to receive payment of the Redemption Price plus accrued interest, if any. 145385.01 8. Offers to Purchase. Sections 4.15 and 4.16 of the Indenture provide that, after certain Asset Sales (as defined in the Indenture) and upon the occurrence of a Change of Control (as defined in the Indenture), and subject to further limitations contained therein, the Issuers will make an offer to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture. 9. Registration Rights. Pursuant to the Registration Rights Agreement among the Issuers, the Subsidiary Guarantors and the Initial Purchasers, the Issuers and the Subsidiary Guarantors will be obligated to consummate an exchange offer pursuant to which the Holder of this Note shall have the right to exchange this Note for the Issuers' 11 1/2% Senior Notes due 2004, Series B (the "Exchange Notes"), which have been registered under the Securities Act, in like principal amount and having terms identical in all material respects as the Initial Notes. The Holders of the Initial Notes shall be entitled to receive certain additional interest payments in the event such exchange offer is not consummated and upon certain other conditions, all pursuant to and in accordance with the terms of the Registration Rights Agreement. 10. Denominations; Transfer; Exchange. The Notes are in registered form, without coupons, and (except Notes issued as payment of Interest) in denominations of $1,000 and integral multiples of $1,000. A Holder shall register the transfer of or exchange Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption. 11. Persons Deemed Owners. The registered Holder of a Note shall be treated as the owner of it for all purposes. 12. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for one year, the Trustee and the Paying Agent will pay the money back to the Issuers. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 13. Discharge Prior to Redemption or Maturity. If the Issuers at any time deposit with the Trustee U.S. Legal Tender or U.S. Government Obligations sufficient to pay the principal of and interest on the Notes to redemption or maturity and comply with the other provisions of the Indenture relating thereto, the Issuers will be discharged from certain provisions of the Indenture and the Notes (including certain covenants, but including, under certain circumstances, their obligation to pay the principal of and interest on the Notes but without affecting the rights of the Holders to receive such amounts from such deposits). 14. Amendment; Supplement; Waiver. Subject to certain exceptions set forth in the Indenture, the Indenture or the Notes may be amended or supplemented with the written consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding, and any past 145385.01 Default or Event of Default or noncompliance with any provision may be waived with the written consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes, comply with any requirements of the Commission in order to effect or maintain the qualification of the Indenture under the TIA or comply with Article Five of the Indenture or make any other change that does not adversely affect the rights of any Holder of a Note. 15. Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Issuers and the Restricted Subsidiaries to, among other things, incur additional Indebtedness, make payments in respect of their Capital Stock or certain Indebtedness, make certain Investments, create or incur liens, enter into transactions with Affiliates, create dividend or other payment restrictions affecting Restricted Subsidiaries, issue Preferred Stock of their Restricted Subsidiaries, and on the ability of the Issuers and their Restricted Subsidiaries to merge or consolidate with any other Person or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of the Issuers' and their Restricted Subsidiaries' assets or adopt a plan of liquidation. Such limitations are subject to a number of important qualifications and exceptions. Pursuant to Section 4.06 of the Indenture, the Issuer must annually report to the Trustee on compliance with such limitations. 16. Successors. When a successor assumes, in accordance with the Indenture, all the obligations of its predecessor under the Notes and the Indenture, the predecessor, subject to certain exceptions, will be released from those obligations. 17. Defaults and Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of not less than 25% in aggregate principal amount of Notes then outstanding may declare all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity reasonably satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal or interest when due, for any reason or a Default in compliance with Article Five of the Indenture) if it determines that withholding notice is in their interest. 18. Trustee Dealings with Issuers. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuers, their Subsidiaries or their respective Affiliates as if it were not the Trustee. 19. No Recourse Against Others. No partner, director, officer, employee or stockholder, as such, of either Issuer or any Subsidiary Guarantor, 145385.01 as such, shall have any liability for any obligations of either Issuer or any Subsidiary Guarantor under the Notes, the Indenture, the Guarantees or the Registration Rights Agreement or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes. 20. Guarantees. This Note will be entitled to the benefits of certain Guarantees, if any, made for the benefit of the Holders. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and obligations thereunder of the Subsidiary Guarantors, the Trustee and the Holders. 21.

Trustee Dealings with Issuers. The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuers, their Subsidiaries or their respective Affiliates as if it were not the Trustee. 18.

The Issuers shall furnish to the Initial Purchasers such conformed copies of such documents, opinions, certificates, letters, schedules and instruments in such quantities as the Initial Purchasers shall reasonably request. 8. Offering of Securities; Restrictions on Transfer. (a)Each of the Initial Purchasers represents and warrants (as to itself only) that it is a QIB. Each of the Initial Purchasers agrees with the Issuers (as to itself only) that (i) it has not and will not solicit offers for, or offer or sell, the Securities by any form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Act; and (ii) it has and will solicit offers for the Securities only from, and will offer the Securities only to (A) in the case of offers inside the United States, (x) persons whom the Initial Purchasers reasonably believe to be QIBs or, if any such person is buying for one or more institutional accounts for which such person is acting as fiduciary or agent, only when such person has represented to the Initial Purchasers that each such account is a QIB, to whom notice has been given that such sale or delivery is being made in reliance on Rule 144A, and, in each case, in transactions under Rule 144A or (y) a limited number of other institutional investors reasonably believed by the Initial Purchasers to be Accredited Investors that, prior to their purchase of the Securities, deliver to the Initial Purchasers a letter containing the representations and agreements set forth in Annex A to the Final Memorandum and (B) in the case of offers outside the United States, to persons other than U.S. persons ("foreign purchasers," which term shall include dealers or other professional fiduciaries in the United States acting on a discretionary basis for foreign beneficial owners (other than an estate or trust)); provided, however, that, in the case of this clause (B), in purchasing such Securities such persons are deemed to have represented and agreed as provided under the caption "Transfer Restrictions" contained in the Final Memorandum (or, if the Final Memorandum is not in existence, in the most 28 recent Memorandum). (b) Each of the Initial Purchasers represents and warrants (as to itself only) with respect to offers and sales outside the United States that (i) it has and will comply with all applicable laws and regulations in each jurisdiction in which it acquires, offers, sells or delivers Securities or has in its possession or distributes any Memorandum or any such other material, in all cases at its own expense including, without limitation, that the Securities have not been and will not be offered or sold to residents of the Province of Alberta, Canada; (ii) the Securities have not been and will not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with Regulation S under the Act or pursuant to an exemption from the registration requirements of the Act; (iii) it has offered the Securities and will offer and sell the Securities (A) as part of its distribution at any time and (B) otherwise until 40 days after the later of the commencement of the offering and the Closing Date, only in accordance with Rule 903 of Regulation S and, accordingly, neither it nor any persons acting on its behalf have engaged or will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Securities, and any such persons have complied and will comply with the offering restrictions requirement of Regulation S; and (iv) it agrees that, at or prior to confirmation of sales of the Securities, it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it during the restricted period a confirmation or notice to substantially the following effect: "The Securities covered hereby have not been registered under the United States Securities Act of 1933 (the "Securities Act") and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of the distribution of the Securities at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and the closing date of the offering, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meaning given to them in Regulation S." Terms used in this Section 8(b) and not defined in this Agreement have the meanings given to them in Regulation S. (c) Each of the Initial Purchasers represents and warrants (as to itself only) that the source of funds being used by it to acquire the Securities does not include the assets of any "employee benefit plan" (within the meaning of Section 3 of ERISA) or any "plan" (within the meaning of Section 4975 of the Code). 9. Indemnification and Contribution. (a)The Issuers and any Subsidiary Guarantors agree, jointly and severally, to indemnify and hold harmless the Initial Purchasers, their affiliates and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which any Initial Purchaser or such controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon: 29 (i) any untrue statement or alleged untrue statement of any material fact contained in any Memorandum or any amendment or supplement thereto or any application or other document, or any amendment or supplement thereto, executed by an Issuer or based upon written information furnished by or on behalf of an Issuer filed in any jurisdiction in order to qualify the Securities under the securities or "Blue Sky" laws thereof or filed with any securities association or securities exchange (each an "Application"); or (ii) the omission or alleged omission to state, in any Memorandum or any amendment or supplement thereto or any Application, a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and will reimburse, as incurred, the Initial Purchasers, each such affiliate and each such controlling person for any reasonable legal or other reasonable expenses incurred by the Initial Purchasers, such affiliate or such controlling person in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, that the Issuers and the Subsidiary Guarantors will not be liable (i) in any such case to the extent that any such loss, claim, damage, or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in any Memorandum or any amendment or supplement thereto or any Application in reliance upon and in conformity with written information concerning the Initial Purchasers furnished to an Issuer by the Initial Purchasers specifically for use therein or (ii) with respect to the Preliminary Memorandum, to the extent that any such loss, claim, damage or liability arises solely from the fact that the Initial Purchasers sold Securities to a person to whom there was not sent or given, on or prior to the written confirmation of such sale, a copy of the Final Memorandum, as amended and supplemented, if the Issuers shall have previously furnished copies thereof to the Initial Purchasers in accordance with this Agreement and the Final Memorandum, as amended and supplemented, would have corrected any such untrue statement or omission. This indemnity agreement will be in addition to any liability that the Issuers and the Subsidiary Guarantors may otherwise have to the indemnified parties. The Issuers and the Subsidiary Guarantors shall not be liable under this Section 9 for any settlement of any claim or action effected without their prior written consent, which shall not be unreasonably withheld. The Initial Purchasers shall not, without the prior written consent of the Issuers, effect any settlement or compromise of any pending or threatened proceeding in respect of which any Issuer is or could have been a party, or indemnity could have been sought hereunder by any Issuer, unless such settlement (A) included an unconditional written release of the Issuers, in form and substance reasonably satisfactory to the Issuers, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any Issuer. 30 (b) The Initial Purchasers agree, severally and not jointly, to indemnify and hold harmless the Issuers and the Subsidiary Guarantors, their respective directors and their respective officers and each person, if any, who controls an Issuer within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which an Issuer or any of the Subsidiary Guarantors or any such director, officer or controlling person may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in any Memorandum or any amendment or supplement thereto or any Application, or (ii) the omission or the alleged omission to state therein a material fact required to be stated in any Memorandum or any amendment or supplement thereto or any Application, or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser, furnished to an Issuer by such Initial Purchaser specifically for use therein; and subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any reasonable legal or other expenses incurred by an Issuer or any of the Subsidiary Guarantors or any such director, officer or controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability that the Initial Purchasers may otherwise have to the indemnified parties. The Initial Purchasers shall not be liable under this Section 9 for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld. The Issuers shall not, without the prior written consent of the Initial Purchasers, effect any settlement or compromise of any pending or threatened proceeding in respect of which any Initial Purchaser is or could have been a party, or indemnity could have been sought hereunder by any Initial Purchaser, unless such settlement (A) includes an unconditional written release of the Initial Purchasers, in form and substance reasonably satisfactory to the Initial Purchasers, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any Initial Purchaser. (c) Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 9, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party of the commencement thereof in writing; but the omission to so notify the indemnifying party (i) will not relieve the indemnifying party from any liability under paragraph (a) or (b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement 31 thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to direct the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations or circumstances, designated by the Initial Purchasers in the case of paragraph (a) of this Section 9 or the Issuers in the case of paragraph (b) of this Section 9, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 9, in which case the indemnified party may effect such a settlement without such consent. (d) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 9 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Securities or (ii) if the allocation provided 32 by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Issuers on the one hand and any Initial Purchaser on the other shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Issuers bear to the total discounts and commissions received by such Initial Purchaser. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers on the one hand, or such Initial Purchaser on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Issuers and the Initial Purchasers agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Initial Purchaser shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Initial Purchaser under this Agreement, less the aggregate amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of the untrue or alleged untrue statements or the omissions or alleged omissions to state a material fact, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each affiliate of an Initial Purchaser, each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each director of an Issuer, each officer of an Issuer and each person, if any, who controls an Issuer within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Issuers. 10. Survival Clause. The respective representations, warranties, agreements, covenants, indemnities and other statements of the Issuers, their respective officers and the Initial Purchasers set forth in this Agreement or made by or on behalf of them pursuant to this Agreement shall remain in full force and effect, regardless of (i) any investigation made by or on behalf of the Issuers, any of their respective officers or directors, the Initial Purchasers or any controlling person referred to in Section 9 hereof and (ii) delivery of and payment for the Securities. The respective agreements, covenants, indemnities and other statements set forth in Sections 6, 9 and 15 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement. 11. Termination. (a)This Agreement may be terminated in the sole discretion of the Initial Purchasers by notice to the Issuers given prior to the Closing Date in the event that either of the Issuers shall have failed, refused or been unable to perform all obligations and satisfy all conditions on its part 33 to be performed or satisfied hereunder at or prior thereto or, if at or prior to the Closing Date: (i) either of the Issuers shall have sustained any loss or interference with respect to its businesses or properties from fire, flood, hurricane, accident or other calamity, whether or not covered by insurance, or from any strike, labor dispute, slow down or work stoppage or any legal or governmental proceeding, which loss or interference, in the sole judgment of the Initial Purchasers, has had or has a Material Adverse Effect, or there shall have been, in the sole judgment of the Initial Purchasers, any event or development that, individually or in the aggregate, has or could be reasonably likely to have a Material Adverse Effect (including without limitation a change in control of any of the Issuers or the Subsidiaries), except in each case as described in the Final Memorandum (exclusive of any amendment or supplement thereto); (ii) trading in securities generally on the New York Stock Exchange, American Stock Exchange or the NASDAQ National Market shall have been suspended or minimum or maximum prices shall have been established on any such exchange or market; (iii) a banking moratorium shall have been declared by New York or United States authorities; (iv) there shall have been (A) an outbreak or escalation of hostilities between the United States and any foreign power, or (B) an outbreak or escalation of any other insurrection or armed conflict involving the United States or any other national or international calamity or emergency, or (C) any material change in the financial markets of the United States which, in the case of (A), (B) or (C) above and in the sole judgment of the Initial Purchasers, makes it impracticable or inadvisable to proceed with the offering or the delivery of the Securities as contemplated by the Final Memorandum; or (v) any securities of the Issuers shall have been downgraded or placed on any "watch list" for possible downgrading by any nationally recognized statistical rating organization. (b) Termination of this Agreement pursuant to this Section 11 shall be without liability of any party to any other party except as provided in Section 10 hereof. 12. Information Supplied by the Initial Purchasers.

THE VALIDITY AND INTERPRETATION OF THIS AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED WHOLLY THEREIN, WITHOUT GIVING EFFECT TO ANY PROVISIONS THEREOF RELATING TO CONFLICTS OF LAW. 16. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 17. Miscellaneous. If, on the Closing Date, any of the Initial Purchasers shall fail or refuse to purchase Securities that it has agreed to purchase hereunder on such date, and the aggregate amount of Securities which such defaulting Initial Purchaser agreed but failed and refused to purchase is not more than ten percent of the aggregate amount of Securities to be purchased 35 on such date, the other Initial Purchasers shall be obligated to purchase the Securities which such defaulting Initial Purchaser agreed but failed or refused to purchase on such date. If, on the Closing Date, any Initial Purchaser shall fail or refuse to purchase Securities which it agreed to purchase hereunder on such date and the aggregate amount of Securities with respect to which such default occurs is more than ten percent of the aggregate amount of Securities to be purchased on such date and arrangements satisfactory to the nondefaulting Initial Purchasers and the Company for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any nondefaulting Initial Purchasers or of the Company, except as provided in Section 10. In any such case either the nondefaulting Initial Purchaser or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Final Memorandum or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Initial Purchaser from liability in respect to any default of such Initial Purchaser under this Agreement. 18.

Exchange Offer (a) To the extent permitted by applicable law or applicable interpretation of the staff of the Division of Corporation Finance of the SEC, the Issuers shall file with the SEC, no later than the Filing Date, a Registration Statement (the "Exchange Offer Registration Statement") on an appropriate registration form with respect to a registered offer (the "Exchange Offer") to exchange any and all of the Registrable Notes for a like aggregate principal amount of notes (the "Exchange Notes") of the Issuers (the guarantees, if any, of the Subsidiary Guarantors) that are identical in all material respects to the Notes except that the Exchange Notes (and the guarantees, if any, of the Subsidiary Guarantors) shall contain no restrictive legend thereon. The Exchange Offer shall comply with all 4 145391.01 applicable tender offer rules and regulations under the Exchange Act and other applicable law. The Issuers shall use their respective best efforts to (x) cause the Exchange Offer Registration Statement to be declared effective under the Securities Act on or before the Effectiveness Date; (y) keep the Exchange Offer open for at least 30 days (or longer if required by applicable law) after the date that notice of the Exchange Offer is mailed to Holders; and (z) consummate the Exchange Offer on or prior to the 135th day following the date on which the Exchange Offer Registration Statement is declared effective by the SEC. If, after the Exchange Offer Registration Statement is initially declared effective by the SEC, the Exchange Offer or the issuance of the Exchange Notes thereunder is interfered with by any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court, the Exchange Offer Registration Statement shall be deemed not to have become effective for purposes of this Agreement. Each Holder that participates in the Exchange Offer will be required to represent that any Exchange Notes to be received by it will be acquired in the ordinary course of its business, that at the time of the consummation of the Exchange Offer such Holder will have no arrangement or understanding with any Person to participate in the distribution of the Exchange Notes in violation of the provisions of the Securities Act, and that such Holder is not an affiliate of any of the Issuers within the meaning of the Securities Act. Upon consummation of the Exchange Offer in accordance with this Section 2, the provisions of this Agreement shall continue to apply, mutatis mutandis, solely with respect to Registrable Notes that are Private Exchange Notes, Exchange Notes as to which Section 2(c)(iv) is applicable and Exchange Notes held by Participating Broker-Dealers (as defined), and the Issuers shall have no further obligation to register Registrable Notes (other than Private Exchange Notes and other than in respect of any Exchange Notes as to which clause 2(c)(iv) hereof applies) pursuant to Section 3 hereof. No securities other than the Exchange Notes shall be included in the Exchange Offer Registration Statement. (b) The Issuers shall include within the Prospectus contained in the Exchange Offer Registration Statement a section entitled "Plan of Distribution," reasonably acceptable to the Holders, which shall contain a summary statement of the positions taken or policies made by the staff of the SEC with respect to the potential "underwriter" status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such broker-dealer in the Exchange Offer (a "Participating Broker-Dealer"), whether such positions or policies have been publicly disseminated by the staff of the SEC or such positions or policies represent the prevailing views of the staff of the SEC. Such "Plan of Distribution" section shall also expressly permit, to the extent permitted by applicable policies and regulations of the SEC, the use of the Prospectus by all Persons subject to the prospectus delivery requirements of the Securities Act, including, to the extent permitted by applicable policies and regulations of the SEC, all Participating Broker-Dealers, and include a statement describing the means by which 5 145391.01 Participating Broker-Dealers may resell the Exchange Notes in compliance with the Securities Act. The Issuers shall use their respective best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the Prospectus contained therein in order to permit such Prospectus to be lawfully delivered by all Persons subject to the prospectus delivery requirements of the Securities Act for such period of time as is necessary to comply with applicable law in connection with any resale of the Exchange Notes covered thereby; provided, however, that such period shall not exceed 180 days after such Exchange Offer Registration Statement is declared effective (or such longer period if extended pursuant to the last paragraph of Section 5 hereof) (the "Applicable Period"). If, prior to consummation of the Exchange Offer, any Holder holds any Notes acquired by it that have, or that are reasonably likely to be determined to have, the status of an unsold allotment in an initial distribution, or any Holder is not entitled to participate in the Exchange Offer, the Issuers upon the request of any such Holder shall simultaneously with the delivery of the Exchange Notes in the Exchange Offer, issue and deliver to any such Holder, in exchange (the "Private Exchange") for such Notes held by any such Holder, a like principal amount of notes (the "Private Exchange Notes") of the Issuers that are identical in all material respects to the Exchange Notes and the Subsidiary Guarantors if any shall guarantee such Private Exchange Notes. The Private Exchange Notes shall be issued pursuant to the same indenture as the Exchange Notes and bear the same CUSIP number as the Exchange Notes. Interest on the Exchange Notes and the Private Exchange Notes will accrue from (A) the later of (i) the last interest payment date on which interest was paid on the Notes surrendered in exchange therefor or (ii) if the Notes are surrendered for exchange on a date in a period which includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date or (B) if no interest has been paid on the Notes, from the date of the original issuance of the Notes. In connection with the Exchange Offer, the Issuers shall: (1) mail, or cause to be mailed, to each Holder entitled to participate in the Exchange Offer a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; (2) keep the Exchange Offer open for not less than 30 days after the date that notice of the Exchange Offer is mailed to Holders (or longer if required by applicable law); (3) utilize the services of a depositary for the Exchange Offer with an address in the Borough of Manhattan, The City of New York; 6 145391.01 (4) permit Holders to withdraw tendered Notes at any time prior to the close of business, New York time, on the last business day on which the Exchange Offer shall remain open; and (5) otherwise comply in all material respects with all applicable laws, rules and regulations. As soon as practicable after the close of the Exchange Offer and the Private Exchange, if any, the Issuers shall: (1) accept for exchange all Registrable Notes validly tendered and not validly withdrawn pursuant to the Exchange Offer and the Private Exchange, if any; (2) deliver to the Trustee for cancellation all Registrable Notes so accepted for exchange; and (3) cause the Trustee to authenticate and deliver promptly to each Holder of Notes, Exchange Notes or Private Exchange Notes, as the case may be, equal in principal amount to the Notes of such Holder so accepted for exchange. The Exchange Offer and the Private Exchange shall not be subject to any conditions, other than that (i) the Exchange Offer or Private Exchange, as the case may be, does not violate applicable law or any applicable interpretation of the staff of the SEC, (ii) no action or proceeding shall have been instituted or threatened in any court or by any governmental agency which might materially impair the ability of the Issuers to proceed with the Exchange Offer or the Private Exchange, and no material adverse development shall have occurred in any existing action or proceeding with respect to the Issuers and (iii) all governmental approvals shall have been obtained, which approvals the Issuers deem necessary for the consummation of the Exchange Offer or Private Exchange. The Exchange Notes and the Private Exchange Notes shall be issued under (i) the Indenture or (ii) an indenture identical in all material respects to the Indenture and which, in either case, has been qualified under the TIA or is exempt from such qualification and shall provide that the Exchange Notes shall not be subject to the transfer restrictions set forth in the Indenture. The Indenture or such indenture shall provide that the Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent together on all matters as one class and that none of the Exchange Notes, the Private Exchange Notes or the Notes will have the right to vote or consent as a separate class on any matter. (c) If, (i) because of any change in law or in currently prevailing interpretations of the staff of the SEC, the Issuers are not permitted to effect the Exchange Offer, (ii) the Exchange Offer is not consummated within 150 days of the Issue Date, (iii) any holder of Private Exchange Notes so requests in writing to the Issuers within 60 days after the consummation of the Exchange 7 145391.01 Offer, or (iv) in the case of any Holder that participates in the Exchange Offer, such Holder does not receive Exchange Notes on the date of the exchange that may be sold without restriction under state and federal securities laws (other than due solely to the status of such Holder as an affiliate of any of the Issuers within the meaning of the Securities Act) and so notifies the Issuers within 30 days after such Holder first becomes aware of such restrictions, in the case of each of clauses (i) to and including (iv) of this sentence, then the Issuers shall promptly deliver to the Holders and the Trustee written notice thereof (the "Shelf Notice") and shall file a Shelf Registration pursuant to Section 3 hereof. 3. Shelf Registration If at any time a Shelf Notice is delivered as contemplated by Section 2(c) hereof, then: (a) Shelf Registration. The Issuers shall file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes not exchanged in the Exchange Offer, Private Exchange Notes and Exchange Notes as to which Section 2(c)(iv) is applicable (the "Initial Shelf Registration"). The Issuers shall use their respective diligent best efforts to file with the SEC the Initial Shelf Registration on or before the applicable Filing Date. The Initial Shelf Registration shall be on Form S-1 or another appropriate form permitting registration of such Registrable Notes for resale by Holders in the manner or manners designated by them (including, without limitation, one or more underwritten offerings). The Issuers shall not permit any securities other than the Registrable Notes to be included in the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below). The Issuers shall use their respective best efforts to cause the Initial Shelf Registration to be declared effective under the Securities Act on or prior to the Effectiveness Date and to keep the Initial Shelf Registration continuously effective under the Securities Act until the date which is three years from the Effectiveness Date, subject to extension pursuant to the last paragraph of Section 5 hereof (the "Effectiveness Period"), or such shorter period ending when (i) all Registrable Notes covered by the Initial Shelf Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration or (ii) a Subsequent Shelf Registration covering all of the Registrable Notes covered by and not sold under the Initial Shelf Registration or an earlier Subsequent Shelf Registration has been declared effective under the Securities Act; provided, however, that the Effectiveness Period in respect of the Initial Shelf Registration shall be extended to the extent required to permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under the Securities Act and as otherwise provided herein and shall be subject to reduction to the extent that the applicable provisions of Rule 144 are amended or revised. No holder of Registrable Notes may include any of its Registrable Notes in any Shelf Registration Statement pursuant to this Agreement unless and until such holder furnishes to the Issuers in writing, within 30 days after 8 145391.01 receipt of a request therefor, such information as the Issuers may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary prospectus included therein. No holder of Registrable Notes shall be entitled to Additional Interest pursuant to Section 4 hereof unless and until such holder shall have provided all such reasonably requested information. Each holder of Registrable Notes as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Issuers all information required to be disclosed in order to make information previously furnished to the Issuers by such Holder not materially misleading. (b) Subsequent Shelf Registrations. If the Initial Shelf Registration or any Subsequent Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the securities registered thereunder), the Issuers shall use their respective best efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within 30 days of such cessation of effectiveness amend the Initial Shelf Registration in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional "shelf" Registration Statement pursuant to Rule 415 covering all of the Registrable Notes covered by and not sold under the Initial Shelf Registration or an earlier Subsequent Shelf Registration (each, a "Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed, the Issuers shall use their respective best efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities Act as soon as practicable after such filing and to keep such subsequent Shelf Registration continuously effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf Registration or any Subsequent Shelf Registration was previously continuously effective. As used herein the term "Shelf Registration" means the Initial Shelf Registration and any Subsequent Shelf Registration. (c) Supplements and Amendments. The Issuers shall promptly supplement and amend any Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used for such Shelf Registration, if required by the Securities Act, or if reasonably requested by the Holders of a majority in aggregate principal amount of the Registrable Notes covered by such Registration Statement or by any underwriter of such Registrable Notes. 4. Additional Interest (a) The Issuers and the Initial Purchasers agree that the Holders will suffer damages if the Issuers fail to fulfill their obligations under Section 2 or Section 3 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Issuers agree, jointly and severally, to pay, as liquidated damages, additional interest on the Notes ("Additional Interest") under the circumstances and to the extent set forth below (each of which shall be given independent effect): (i) if (A) neither the Exchange Offer Registration Statement nor the Initial Shelf Registration has been filed on or prior to the applicable 9 145391.01 Filing Date or (B) notwithstanding that the Issuers have consummated or will consummate the Exchange Offer, the Issuers are required to file a Shelf Registration and such Shelf Registration is not filed on or prior to the Filing Date applicable thereto, then, commencing on the day after any such Filing Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.50% per annum for the first 90 days immediately following each such Filing Date, and such Additional Interest rate shall increase by an additional 0.50% per annum at the beginning of each subsequent 90-day period; or (ii) if (A) neither the Exchange Offer Registration Statement nor the Initial Shelf Registration is declared effective by the SEC on or prior to the relevant Effectiveness Date or (B) notwithstanding that the Issuers have consummated or will consummate the Exchange Offer, the Issuers are required to file a Shelf Registration and such Shelf Registration is not declared effective by the SEC on or prior to the Effectiveness Date in respect of such Shelf Registration, then, commencing on the day after such Effectiveness Date, Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.50% per annum for the first 90 days immediately following the day after such Effectiveness Date, and such Additional Interest rate shall increase by an additional 0.50% per annum at the beginning of each subsequent 90-day period; or (iii) if (A) the Issuers have not exchanged Exchange Notes for all Notes validly tendered in accordance with the terms of the Exchange Offer on or prior to the 135th day after the date on which the Exchange Offer Registration Statement relating thereto was declared effective or (B) if applicable, a Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period, then Additional Interest shall accrue on the principal amount of the Notes at a rate of 0.50% per annum for the first 90 days commencing on the (x) 151st day after such effective date, in the case of (A) above, or (y) the day such Shelf Registration ceases to be effective in the case of (B) above, and such Additional Interest rate shall increase by an additional 0.50% per annum at the beginning of each such subsequent 90-day period; provided, however, that the Additional Interest rate on the Notes may not exceed at any one time in the aggregate 1.50% per annum; provided, further, however, that (1) upon the filing of the applicable Exchange Offer Registration Statement or the applicable Shelf Registration as required hereunder (in the case of clause (i) above of this Section 4), (2) upon the effectiveness of the Exchange Offer Registration Statement or the applicable Shelf Registration Statement as required hereunder (in the case of clause (ii) of this Section 4), or (3) upon the exchange of the applicable Exchange Notes for all Notes tendered (in the case of clause (iii)(A) of this Section 4), or upon the effectiveness of the applicable Shelf Registration Statement which had ceased to remain effective (in the case of (iii)(B) of this Section 4), Additional Interest on the Notes in respect of which such events relate as a result of such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. 10 145391.01 (b) The Issuers shall notify the Trustee within one business day after each and every date on which an event occurs in respect of which Additional Interest is required to be paid (an "Event Date"). Any amounts of Additional Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be payable in cash semi-annually on each May 1 and November 1 (to the holders of record on the April 15 and October 15 immediately preceding such dates), commencing with the first such date occurring after any such Additional Interest commences to accrue. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest rate by the principal amount of the Registrable Notes, multiplied by a fraction, the numerator of which is the number of days such Additional Interest rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which is 360. 5. Registration Procedures In connection with the filing of any Registration Statement pursuant to Sections 2 or 3 hereof, the Issuers shall effect such registrations to permit the sale of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Issuers hereunder the Issuers shall: (a) Prepare and file with the SEC prior to the applicable Filing Date, a Registration Statement or Registration Statements as prescribed by Sections 2 or 3 hereof, and use their respective best efforts to cause each such Registration Statement to become effective and remain effective as provided herein; provided, however, that, if (1) such filing is pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period relating thereto, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Issuers shall furnish to and afford the Holders of the Registrable Notes covered by such Registration Statement or each such Participating Broker-Dealer, as the case may be, their counsel and the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including copies of any documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least five days prior to such filing, or such later date as is reasonable under the circumstances). The Issuers shall not file any Registration Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in aggregate principal amount of the Registrable Notes covered by such Registration Statement, or any such Participating Broker-Dealer, as the case may be, their counsel, or the managing underwriters, if any, shall reasonably object. 11 145391.01 (b) Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration Statement or Exchange Offer Registration Statement, as the case may be, as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period or the Applicable Period, as the case may be; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply with the provisions of the Securities Act and the Exchange Act applicable to each of them with respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented and with respect to the subsequent resale of any securities being sold by a Participating Broker-Dealer covered by any such Prospectus. The Issuers shall be deemed not to have used their respective diligent best efforts to keep a Registration Statement effective during the Effective Period or the Applicable Period, as the case may be, relating thereto if any of the Issuers voluntarily takes any action that would result in selling Holders of the Registrable Notes covered thereby or Participating Broker-Dealers seeking to sell Exchange Notes not being able to sell such Registrable Notes or such Exchange Notes during that period unless (i) such action is required by applicable law or (ii) such Issuers comply with the provisions of the last sentence of Section 5(k) or the last paragraph of this Section 5. (c) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period relating thereto from whom the Company has received written notice that it will be a Participating Broker-Dealer in the Exchange Offer, notify the selling Holders of Registrable Notes, or each such Participating Broker-Dealer, as the case may be, their counsel and the managing underwriters, if any, promptly (but in any event within one day), and confirm such notice in writing, (i) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under the Securities Act (including in such notice a written statement that any Holder may, upon request, obtain, at the sole expense of the Issuers, one conformed copy of such Registration Statement or post-effective amendment including financial statements and schedules, documents incorporated or deemed to be incorporated by reference and exhibits), (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of any preliminary prospectus or the initiation of any proceedings for that purpose, (iii) if at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of the Registrable Notes or resales of Exchange Notes by Participating Broker-Dealers the representations and warranties of any of the Issuers contained in any agreement (including any underwriting agreement) contemplated by Section 5(m) hereof cease to be true and correct in all 12 145391.01 material respects, (iv) of the receipt by any of the Issuers of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Notes or the Exchange Notes to be sold by any Participating Broker-Dealer for offer or sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, (v) of the happening of any event, the existence of any condition or any information becoming known that makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments or supplements to such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vi) of any of the Issuers' determination that a post-effective amendment to a Registration Statement would be appropriate. (d) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, use their respective best efforts to prevent the issuance of any order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Notes or the Exchange Notes to be sold by any Participating Broker-Dealer, for sale in any jurisdiction, and, if any such order is issued, to use their respective best efforts to obtain the withdrawal of any such order at the earliest possible date. (e) Subject to the provisions of the last sentence of Section 5(k), if a Shelf Registration is filed pursuant to Section 3 and if requested by the managing underwriter or underwriters (if any), the Holders of a majority in aggregate principal amount of the Registrable Notes being sold in connection with an underwritten offering or any Participating Broker-Dealer, (i) promptly as practicable incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters (if any), such Holders, any Participating Broker-Dealer or counsel for any of them reasonably request to be included therein, (ii) make all required filings of such prospectus supplement or such post-effective amendment as soon as practicable after either Issuer has received notification of the matters to be incorporated in such prospectus supplement or post-effective amendment, and (iii) supplement or make amendments to such Registration Statement; provided, however, that the Issuers shall not be required to take any action pursuant to this 13 145391.01 Section 5(e) that would violate applicable law. (f) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, furnish to each selling Holder of Registrable Notes and to each such Participating Broker-Dealer who so requests and to counsel and each managing underwriter, if any, at the sole expense of the Issuers, one conformed copy of the Registration Statement or Registration Statements and each post-effective amendment thereto, including financial statements and schedules, and, if requested, all documents incorporated or deemed to be incorporated therein by reference and all exhibits. (g) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, deliver to each selling Holder of Registrable Notes, or each such Participating Broker-Dealer, as the case may be, their respective counsel, and the underwriters, if any, at the sole expense of the Issuers, as many copies of the Prospectus or Prospectuses (including each form of preliminary prospectus) and each amendment or supplement thereto and any documents incorporated by reference therein as such Persons may reasonably request; and, subject to the last paragraph of this Section 5, each of the Issuers hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders of Registrable Notes or each such Participating Broker-Dealer, as the case may be, and the underwriters or agents, if any, and dealers (if any), in connection with the offering and sale of the Registrable Notes covered by, or the sale by Participating Broker-Dealers of the Exchange Notes pursuant to, such Prospectus and any amendment or supplement thereto. (h) Prior to any public offering of Registrable Notes or any delivery of a Prospectus contained in the Exchange Offer Registration Statement by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, to use their respective best efforts to register or qualify, and to cooperate with the selling Holders of Registrable Notes or each such Participating Broker-Dealer, as the case may be, the managing underwriter or underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Notes for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any selling Holder, Participating Broker-Dealer, or the managing underwriter or underwriters reasonably request in writing; provided, however, that where Exchange Notes held by Participating Broker-Dealers or Registrable Notes are offered other than through an underwritten offering, the Issuers agree to cause their counsel to perform Blue Sky investigations and file 14 145391.01 registrations and qualifications required to be filed pursuant to this Section 5(h); keep each such registration or qualification (or exemption therefrom) effective during the period such Registration Statement is required to be kept effective and do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of the Exchange Notes held by Participating Broker-Dealers or the Registrable Notes covered by the applicable Registration Statement; provided, however, that none of the Issuers shall be required to (A) qualify generally to do business in any jurisdiction where it is not then so qualified, (B) take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject or (C) subject itself to taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject. (i) If a Shelf Registration is filed pursuant to Section 3 hereof, cooperate with the selling Holders of Registrable Notes and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Notes to be sold, which certificates shall not bear any restrictive legends and shall be in a form eligible for deposit with The Depository Trust Company; and enable such Registrable Notes to be in such denominations and registered in such names as the managing underwriter or underwriters, if any, or Holders may request. (j) Use their respective best efforts to cause the Registrable Notes covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be reasonably necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to consummate the disposition of such Registrable Notes, except as may be required solely as a consequence of the nature of such selling Holder's business, in which case the Issuers will cooperate in all reasonable respects with the filing of such Registration Statement and the granting of such approvals. (k) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, upon the occurrence of any event contemplated by paragraph 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable prepare and (subject to Section 5(a) hereof) file with the SEC, at the sole expense of the Issuers, a supplement or post-effective amendment to the Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, or file any other required document so that, as thereafter delivered to the purchasers of the Registrable Notes being sold thereunder or to the purchasers of the Exchange Notes to whom such Prospectus will be delivered by a Participating Broker-Dealer, any such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary 15 145391.01 to make the statements therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the Issuers shall not be required to amend or supplement a Registration Statement, any related prospectus or any document incorporated therein by reference in the event that, and for a period (a "Black Out Period") not to exceed, for so long as this Agreement is in effect, an aggregate of 45 days if (x) an event occurs and is continuing as a result of which a Registration Statement, any related prospectus or any document incorporated therein by reference as then amended or supplemented would, in the Issuers' good faith judgment, contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and (y) (1) the Issuers determine in good faith that the disclosure of such event at such time would have a material adverse effect on the business, operations or prospects of the Issuers or (2) the disclosure otherwise relates to a material business transaction which has not yet been publicly disclosed in any relevant jurisdiction. (l) Prior to the effective date of the first Registration Statement relating to the Registrable Notes, (i) provide the Trustee with certificates for the Registrable Notes in a form eligible for deposit with The Depository Trust Company and (ii) provide a CUSIP number for the Registrable Notes. (m) In connection with any underwritten offering of Registrable Notes pursuant to a Shelf Registration, enter into an underwriting agreement as is customary in underwritten offerings of debt securities similar to the Notes in form and substance reasonably satisfactory to the Issuers and take all such other actions as are reasonably requested by the managing underwriter or underwriters in order to expedite or facilitate the registration or the disposition of such Registrable Notes and, in such connection, (i) make such representations and warranties to, and covenants with, the underwriters with respect to the business of the Issuers and their respective subsidiaries (including any acquired business, properties or entity, if applicable) and the Registration Statement, Prospectus and documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, as are customarily made by issuers to underwriters in underwritten offerings of debt securities similar to the Notes, and confirm the same in writing if and when requested in form and substance reasonably satisfactory to the Issuers; (ii) obtain the written opinions of counsel to the Issuers and written updates thereof in form, scope and substance reasonably satisfactory to the managing underwriter or underwriters, addressed to the underwriters covering the matters customarily covered in opinions reasonably requested in underwritten offerings and such other matters as may be reasonably requested by the managing underwriter or underwriters; (iii) use their best efforts to obtain "cold comfort" letters and updates thereof in form, scope and substance reasonably satisfactory to the managing underwriter or underwriters from the independent certified public accountants of the Issuers (and, if necessary, any other independent certified public accountants of any subsidiary of any of the Issuers or of any business 16 145391.01 acquired by any of the Issuers for which financial statements and financial data are, or are required to be, included or incorporated by reference in the Registration Statement), addressed to each of the underwriters, such letters to be in customary form and covering matters of the type customarily covered in "cold comfort" letters in connection with underwritten offerings of debt securities similar to the Notes and such other matters as reasonably requested by the managing underwriter or underwriters as permitted by the Statement on Auditing Standards No. 72; and (iv) if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures no less favorable to the sellers and underwriters, if any, than those set forth in Section 7 hereof (or such other provisions and procedures acceptable to Holders of a majority in aggregate principal amount of Registrable Notes covered by such Registration Statement and the managing underwriter or underwriters or agents, if any). The above shall be done at each closing under such underwriting agreement, or as and to the extent required thereunder. (n) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period, make available for inspection by any selling Holder of such Registrable Notes being sold, or each such Participating Broker-Dealer, as the case may be, any underwriter participating in any such disposition of Registrable Notes, if any, and any attorney, accountant or other agent retained by any such selling Holder or each such Participating Broker-Dealer, as the case may be, or underwriter (collectively, the "Inspectors"), at the offices where normally kept, during reasonable business hours, all financial and other records, pertinent corporate documents and instruments of the Issuers and their respective subsidiaries (collectively, the "Records") as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, directors and employees of the Issuers and their respective subsidiaries to supply all information reasonably requested by any such Inspector in connection with such Registration Statement and Prospectus. Each Inspector shall agree in writing that it will keep the Records confidential and that it will not disclose any of the Records unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in such Registration Statement or Prospectus, (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, (iii) disclosure of such information is necessary or advisable, in the opinion of counsel for any Inspector, in connection with any action, claim, suit or proceeding, directly or indirectly, involving or potentially involving such Inspector and arising out of, based upon, relating to, or involving this Agreement or the Purchase Agreement, or any transactions contemplated hereby or thereby or arising hereunder or thereunder, or (iv) the information in such Records has been made generally available to the public; provided, however, that prior notice shall be provided as soon as practicable to the Issuers of the potential disclosure of any information by such Inspector pursuant to clauses (ii) or (iii) of this sentence to permit the Issuers to obtain a protective order (or waive the provisions of this paragraph (n)) and that such Inspector shall take such actions as are reasonably necessary to protect the confidentiality of such information (if practicable) to the extent such action is otherwise not inconsistent with, an impairment of or in derogation of the rights and interests of the Holder or any Inspector. Each selling Holder of such Registrable Notes and each such Participating Broker-Dealer will be required to agree that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Issuers unless and until such is made generally available to the public. Each selling Holder of such Registrable Notes and each such Participating Broker-Dealer will be required to further agree that it will, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Issuers and allow the Issuers to undertake appropriate action to prevent disclosure of the Records deemed confidential at the Issuers' expense. (o) Provide an indenture trustee for the Registrable Notes or the Exchange Notes, as the case may be, and cause the Indenture or the trust indenture provided for in Section 2(a) hereof, as the case may be, to be qualified under the TIA not later than the effective date of the first Registration Statement relating to the Registrable Notes; and in connection therewith, cooperate with the trustee under any such indenture and the Holders of the Registrable Notes, to effect such changes to such indenture as may be required for such indenture to be so qualified in accordance with the terms of the TIA; and execute, and use their respective best efforts to cause such trustee to execute, all documents as may be required to effect such changes, and all other forms and documents 17 145391.01 required to be filed with the SEC to enable such indenture to be so qualified in a timely manner. (p) Comply with all applicable rules and regulations of the SEC and make generally available to their respective securityholders earnings statements satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable Notes are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of the Issuers after the effective date of a Registration Statement, which statements shall cover said 12- month periods. (q) Upon consummation of the Exchange Offer or a Private Exchange, obtain an opinion of counsel to the Issuers, in a form customary for underwritten transactions, addressed to the Trustee for the benefit of all Holders of Registrable Notes participating in the Exchange Offer or the Private Exchange, as the case may be, that the Exchange Notes or Private 18 145391.01 Exchange Notes, as the case may be, and the related indenture constitute legal, valid and binding obligations of the Issuers, enforceable against the Issuers in accordance with its respective terms, subject to customary exceptions and qualifications. (r) If the Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Registrable Notes by Holders to the Issuers (or to such other Person as directed by the Issuers) in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be, the Issuers shall mark, or cause to be marked, on such Registrable Notes that such Registrable Notes are being cancelled in exchange for the Exchange Notes or the Private Exchange Notes, as the case may be; in no event shall such Registrable Notes be marked as paid or otherwise satisfied. (s) Cooperate with each seller of Registrable Notes covered by any Registration Statement and each underwriter, if any, participating in the disposition of such Registrable Notes and their respective counsel in connection with any filings required to be made with the National Association of Securities Dealers, Inc. (the "NASD"). (t) Use their respective best efforts to take all other steps reasonably necessary to effect the registration of the Exchange Notes and/or Registrable Notes covered by a Registration Statement contemplated hereby. The Issuers may require each seller of Registrable Notes as to which any registration is being effected to furnish to the Issuers such information regarding such seller and the distribution of such Registrable Notes as the Issuers may, from time to time, reasonably request. The Issuers may exclude from such registration the Registrable Notes of any seller so long as such seller fails to furnish such information within a reasonable time after receiving such request. Each seller as to which any Shelf Registration is being effected agrees to furnish promptly to the Issuers all information required to be disclosed in order to make the information previously furnished to the Issuers by such seller not materially misleading. If any such Registration Statement refers to any Holder by name or otherwise as the holder of any securities of the Issuers, then such Holder shall have the right to require (i) the insertion therein of language, in form and substance reasonably satisfactory to such Holder, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of any of the Issuers, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the Securities Act or any similar federal statute then in force, the deletion of the reference to such Holder in any amendment or supplement to the Registration Statement filed or prepared subsequent to the time that such reference ceases to be required. 19 145391.01 Each Holder of Registrable Notes and each Participating Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange Notes to be sold by such Participating Broker-Dealer, as the case may be, that, upon actual receipt of any notice from the Issuers of the happening of any event of the kind described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi) hereof, such Holder will forthwith discontinue disposition of such Registrable Notes covered by such Registration Statement or Prospectus or Exchange Notes to be sold by such Holder or Participating Broker-Dealer, as the case may be, until such Holder's or Participating Broker-Dealer's receipt of the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof, or until it is advised in writing (the "Advice") by any of the Issuers that the use of the applicable Prospectus may be resumed, and has received copies of any amendments or supplements thereto. In the event that the Issuers shall give any such notice, each of the Effectiveness Period and the Applicable Period shall be extended by the number of days during such periods from and including the date of the giving of such notice to and including the date when each seller of Registrable Notes covered by such Registration Statement or Exchange Notes to be sold by such Participating Broker-Dealer, as the case may be, shall have received (x) the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof or (y) the Advice. 6. Registration Expenses All fees and expenses incident to the performance of or compliance with this Agreement by the Issuers shall be borne by the Issuers, jointly and severally, whether or not the Exchange Offer Registration Statement or any Shelf Registration is filed or becomes effective or the Exchange Offer is consummated, including, without limitation, (i) all registration and filing fees (including, without limitation, (A) fees with respect to filings required to be made with the NASD in connection with an underwritten offering and (B) fees and expenses of compliance with state securities or Blue Sky laws (including, without limitation, reasonable fees and disbursements of counsel in connection with Blue Sky qualifications of the Registrable Notes or Exchange Notes and determination of the eligibility of the Registrable Notes or Exchange Notes for investment under the laws of such jurisdictions (x) where the holders of Registrable Notes are located, in the case of the Exchange Notes, or (y) as provided in Section 5(h) hereof, in the case of Registrable Notes or Exchange Notes to be sold by a Participating Broker-Dealer during the Applicable Period)), (ii) printing expenses, including, without limitation, expenses of printing certificates for Registrable Notes or Exchange Notes in a form eligible for deposit with The Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by the managing underwriter or underwriters, if any, by the Holders of a majority in aggregate principal amount of the Registrable Notes included in any Registration Statement or in respect of Registrable Notes or Exchange Notes to be sold by any Participating Broker-Dealer during the Applicable Period, as the case may be, (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Issuers and reasonable fees and disbursements of one special counsel for all of the sellers of Registrable Notes (exclusive of any counsel retained pursuant to Section 7 hereof), (v) fees and disbursements of all independent certified public accountants referred to in Section 5(m)(iii) hereof (including, without 20 145391.01 limitation, the expenses of any special audit and "cold comfort" letters required by or incident to such performance), (vi) Securities Act liability insurance, if the Issuers desire such insurance, (vi) fees and expenses of all other Persons retained by any of the Issuers, (viii) internal expenses of the Issuers (including, without limitation, all salaries and expenses of officers and employees of all of the Issuers performing legal or accounting duties), (ix) the expense of any annual audit, (x) the fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange, and the obtaining of a rating of the securities, in each case, if applicable, and (xi) the expenses relating to printing, word processing and distributing all Registration Statements, underwriting agreements, indentures and any other documents necessary in order to comply with this Agreement. 7. Indemnification (a) The Issuers and any Subsidiary Guarantors agree, jointly and severally, to indemnify and hold harmless each Holder of Registrable Notes and each Participating Broker-Dealer selling Exchange Notes during the Applicable Period, the officers, directors, employees and agents of each such Person, and each Person, if any, who controls any such Person within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (each, a "Participant"), from and against any and all losses, claims, damages, judgments, liabilities and expenses (including, without limitation, the reasonable legal fees and other expenses actually incurred in connection with any suit, action or proceeding or any claim asserted) caused by, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement (or any amendment thereto) or Prospectus (as amended or supplemented if any of the Issuers shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by, arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of the Prospectus in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Participant furnished to the Issuers in writing by such Participant expressly for use therein; provided, however, that the Company will not be liable if such untrue statement or omission or alleged untrue statement or omission was contained or made in any preliminary prospectus and corrected in the final Prospectus or any amendment or supplement thereto and any such loss, liability, claim, or damage or expense suffered or incurred by the Participants resulted from any action, claim or suit by any Person who purchased Registrable Notes or Exchange Notes which are the subject thereof from such Participant and it is established in the related proceeding that such Participant failed to deliver or provide a copy of the final Prospectus (as amended or supplemented) to such Person with or prior to the confirmation of the sale of such Registrable Notes or Exchange Notes sold to such Person if required by applicable law. (b) Each Participant agrees, severally and not jointly, to indemnify 21 145391.01 and hold harmless each of the Issuers, their respective directors, their respective officers who sign the Registration Statement and each Person who controls each Issuer within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent (but on a several, and not joint, basis) as the foregoing indemnity from the Issuers to each Participant, but only with reference to information relating to such Participant furnished to the Issuers in writing by such Participant expressly for use in any Registration Statement or Prospectus, any amendment or supplement thereto, or any preliminary prospectus. The liability of any Participant under this paragraph shall in no event exceed the proceeds received by such Participant from sales of Registrable Notes or Exchange Notes giving rise to such obligations. (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 indemnity may be sought pursuant to either of the two preceding paragraphs, such Person (the "Indemnified Person") shall promptly notify the Persons against whom such indemnity may be sought (the "Indemnifying Persons") in writing, and the Indemnifying Persons, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Persons may reasonably designate in such proceeding and shall pay the fees and expenses actually incurred by such counsel related to such proceeding; provided, however, that the failure to so notify the Indemnifying Persons shall not relieve any of them of any obligation or liability which any of them may have hereunder or otherwise. 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 Persons and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Persons shall have failed within a reasonable period of time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include both any Indemnifying Person and the Indemnified Person or any affiliate thereof and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that, unless there exists a conflict among Indemnified Persons, the Indemnifying Persons shall not, in connection with such proceeding or separate but substantially similar related proceeding in the same jurisdiction arising out of the same general allegations, 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 promptly as they are incurred. Any such separate firm for the Participants and such control Persons of Participants shall be designated in writing by Participants who sold a majority in interest of Registrable Notes and Exchange Notes sold by all such Participants and shall be reasonably acceptable to the Issuers and any such separate firm for the Issuers, their respective directors, their respective officers and such control Persons of the Issuers shall be designated in writing by the Issuers and shall be reasonably acceptable to the Holders. The Indemnifying Persons shall not be liable for any settlement of any proceeding effected without its prior written consent (which consent shall not be unreasonably withheld or delayed), but if settled with such consent or if 22 145391.01 there be a final non-appealable judgment for the plaintiff for which the Indemnified Person is entitled to indemnification pursuant to this Agreement, each of the Indemnifying Persons agrees to indemnify and hold harmless each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the prior written consent of the Indemnified Persons (which consent shall not be unreasonably withheld or delayed), effect any settlement or compromise of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party, or indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (A) includes an unconditional written 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 an admission of fault, culpability or failure to act by or on behalf of such Indemnified Person. (d) If the indemnification provided for in the first and second paragraphs of this Section 7 is for any reason unavailable to, or insufficient to hold harmless, an Indemnified Person in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraphs, in lieu of indemnifying such Indemnified Person thereunder and in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect (i) the relative benefits received by the Indemnifying Person or Persons on the one hand and the Indemnified Person or Persons on the other from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the Indemnifying Person or Persons on the one hand and the Indemnified Person or Persons on the other in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative benefits received by the Issuers on the one hand and the Participants on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of discounts and commissions but before deducting expenses) of the Notes received by the Issuers bears to the total proceeds received by such Participant from the sale of Registrable Notes or Exchange Notes, as the case may be, in each case as set forth in the table on the cover page of the Offering Memorandum in respect of the sale of the Notes. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers on the one hand or such Participant or such other Indemnified Person, as the case may be, on the other, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. (e) The parties 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 Participants were treated as one entity for such purpose) or by any 23 145391.01 other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages, judgments, liabilities and expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any reasonable legal or other expenses actually incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall a Participant be required to contribute any amount in excess of the amount by which proceeds received by such Participant from sales of Registrable Notes or Exchange Notes, as the case may be, exceeds the amount of any damages that such Participant has otherwise been required to pay or has paid 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. (f) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 7 shall be paid by the Indemnifying Party to the Indemnified Party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Issuers set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Holder or any person who controls a Holder, any Issuer, their respective directors, officers, employees or agents or any person controlling any Issuer, and (ii) any termination of this Agreement. (g) The indemnity and contribution agreements contained in this Section 7 will be in addition to any liability which the Indemnifying Persons may otherwise have to the Indemnified Persons referred to above. 8. Rules 144 and 144A The Issuers covenant and agree that each of them will file the reports required to be filed by each of them under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, if at any time any of the Issuers is not required to file such reports, such Issuer will, upon the request of any Holder or beneficial owner of Registrable Notes, make available such information necessary to permit sales pursuant to Rule 144A under the Securities Act. The Issuers further covenant and agree, for so long as any Registrable Notes remain outstanding that each of them will take such further action as any Holder of Registrable Notes may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Notes without registration under the Securities Act within the limitation of the exemptions provided by (a) Rule 144(k) and Rule 144A under the Securities Act, as such Rules may be amended from time to time, or (b) any similar rule or regulation hereafter adopted by the SEC. 24 145391.01 25 145391.01 9. Underwritten Registrations If any of the Registrable Notes covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will manage the offering will be selected by the Holders of a majority in aggregate principal amount of such Registrable Notes included in such offering and shall be reasonably acceptable to the Issuers. No Holder of Registrable Notes may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Registrable Notes on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements. 10. Miscellaneous (a) No Inconsistent Agreements. None of the Issuers has, as of the date hereof, and none of the Issuers shall, after the date of this Agreement, enter into any agreement with respect to any of its securities that is inconsistent with the rights granted to the Holders of Registrable Notes in this Agreement or otherwise conflicts with the provisions hereof. 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 of the Issuers' other issued and outstanding securities under any such agreements. Except as otherwise disclosed to the Initial Purchasers, none of the Issuers has entered and none will enter into any agreement with respect to any of its securities which will grant to any Person piggy-back registration rights with respect to any Registration Statement. (b) Adjustments Affecting Registrable Notes. None of the Issuers shall, directly or indirectly, take any action with respect to the Registrable Notes as a class that would adversely affect the ability of the Holders of Registrable Notes to include such Registrable Notes in a registration undertaken pursuant to this Agreement. (c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, otherwise than with the prior written consent of (I) the Issuers and the Subsidiary Guarantors, if any, and (II)(A) the Holders of not less than a majority in aggregate principal amount of the then outstanding Registrable Notes and (B) in circumstances that would adversely affect the Participating Broker-Dealers, the Participating Broker-Dealers holding not less than a majority in aggregate principal amount of the Exchange Notes held by all Participating Broker-Dealers; provided, however, that Section 7 and this Section 10(c) may not be amended, modified or supplemented without the prior written consent of each Holder and each Participating Broker-Dealer (including any person who was a Holder or Participating Broker-Dealer of Registrable Notes or Exchange Notes, as the case may be, disposed of pursuant to 26 145391.01 any Registration Statement) affected by any such amendment, modification or supplement. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Notes whose securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders of Registrable Notes may be given by Holders of at least a majority in aggregate principal amount of the Registrable Notes being sold pursuant to such Registration Statement. (d) Notices. All notices and other communications (including, without limitation, any notices or other communications to the Trustee) provided for or permitted hereunder shall be made in writing by hand-delivery, registered first-class mail, next-day air courier or facsimile: (i) if to a Holder of the Registrable Notes or any Participating Broker-Dealer, at the most current address of such Holder or Participating Broker-Dealer, as the case may be, set forth on the records of the registrar under the Indenture. (ii) if to either of the Issuers or any of the Subsidiary Guarantors, at the address as follows: c/o Abraxas Petroleum Corporation 500 N.

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 and in the manner specified in such Indenture. (e) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties hereto, the Holders and the Participating Broker-Dealers. (f) Release of Subsidiary Guarantors. If any Subsidiary Guarantor becomes a party to this Agreement and is subsequently released from its obligations under the Indenture in accordance with the terms thereof then such 27 145391.01 Subsidiary Guarantor shall be released from its obligations hereunder. (g) 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. (h) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. (i) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED ENTIRELY WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. (j) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their best efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. (k) Securities Held by the Issuers or Their Affiliates. Whenever the consent or approval of Holders of a specified percentage of Registrable Notes is required hereunder, Registrable Notes held by any of the Issuers or any of their their respective affiliates (as such term is defined in Rule 405 under the Securities Act) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

The Vendors hereby authorize the Representative to deliver the Debentures to the Company marked paid-in-full upon payment of the principal and all interest accrued but unpaid thereon as contemplated in Section 9.7. (b) All actions to be taken by the Vendors herein except as may be limited by Section 1.8(a) may be taken by the Representative.

If the Parties are unable to agree on either or both of the said amount or amounts, the said amount or amounts shall be settled by arbitration in accordance with Article 13 and the Closing Date shall be extended in order for the arbitration proceedings to be conducted and the arbitrator's decision to be rendered.

ARTICLE 9 POST-CLOSING MATTERS 9.1 Claims (a) If, at any time, a Party or Parties (herein, whether one or more, a "Notifying Party") believes that it has incurred or suffered or that it will incur or suffer liabilities, losses or costs (herein collectively "Damages") because of the incorrectness or breach of a representation or warranty in Article 3 or 4 (whether as of the date hereof or at the Closing Time) or the certificates delivered by the Company pursuant to Section 6.1 and 6.2 hereof, or the breach of any covenant set forth in Section 2.3(d), 8.1, 8.4, 8.5, 9.3 or 9.6 or this Section 9.1 or Articles 10, 11 or 13, or any amount of Taxes or Alberta Crown Royalties finally established by a Court of competent jurisdiction, or agreed by the Representative to be payable by the Company as the result of an Assessment as contemplated in Section 9.6, or any such amount paid in good faith by the Company or the Purchaser (without the consent of the Representative) with respect to an Assessment as contemplated in Sections 9.6(b) and (d), or any claim by Jefferies for indemnification pursuant to the Jefferies Indemnification Letter as the case may be, or the fraud of the Company or any of the Vendors, as the result of which it has an actual or potential claim for Damages or amounts or that for any other reason it has any claim hereunder (each such claim being referred to as a "Contractual Claim"), the Notifying Party shall forthwith give written notice (herein the "Claim Notice") to the other Parties (herein, whether one or more, the "Receiving Party") and to the Escrow Agent of the matter giving rise to the Contractual Claim. The notification shall specify in reasonable detail the subject matter of the Contractual Claim, to the extent then known to the Notifying Party.

In such event, the Notifying Party shall have the right to retain its own counsel but the fees and expenses of such counsel shall be at the expense of the Notifying Party. The failure to give such notice of intent to defend a Contractual Claim shall constitute a waiver of the Receiving Party's right to defend such Contractual Claim under this Section 9.1(b) and shall preclude the Receiving Party from disputing the manner in which the Notifying Party may in good faith conduct the defence of such Contractual Claim or the reasonableness of any amount paid in good faith by the Notifying Party in satisfaction of such Contractual Claim. The Receiving Party shall not compromise or settle any Contractual Claim without the consent of the Notifying Party, not to be unreasonably withheld. (c) The failure by a Party to give a Claim Notice to the other Parties with respect to any Contractual Claim shall relieve the other Parties of their obligations with respect to the particular Contractual Claim, but only if and to the extent that the other Parties are prejudiced by such failure.

(d) The Parties will cooperate with each other in providing access to their respective records in connection with Contractual Claims. The Purchaser shall preserve such data and other information as may reasonably be required in connection with a Contractual Claim until the end of the limitation period applicable by virtue of Section 5.1(b).

Subject to the last sentence of this Section 9.2(b), in no event will the Purchaser have any claim whatsoever under this Agreement against the Representative, the Vendors or the current or former employees, officers or directors of the Company or any of them personally, nor will the Purchaser be entitled to recover separately or in the aggregate, in respect of all Established Contractual Claims and each of them, an amount in excess of the Escrow Amount. In no event will the limitations in this Section 9.2(b) apply to: (i) any Established Contractual Claim based upon: (A) the fraud of the Company or any of the Vendors; or (B) the incorrectness or breach of any of the representations and warranties set forth in Sections 3.42 to 3.46 inclusive or the breach of any covenants or agreements set forth in Section 2.3(d), 8.1(f), 8.5 or Article 10; or (ii) any claim, right, demand or cause of action relating to or arising out of the incorrectness or breach of any covenant, representation or warranty in any agreement or document entered into or executed by any of the Parties pursuant to the terms hereof or as contemplated hereby; with respect to which the Purchaser or the Vendors, as the case may be, shall be entitled to indemnification as provided herein directly from the other and to such other remedies as may be available at law or in equity. 9.3 Joint Venture Audits (a) Each notice or enquiry received or sent by the Company, or hereafter received or sent by the Company as a result of any joint venture or similar audit (herein a "Joint Venture Audit") conducted before or after August 1, 1996 as to expenses incurred or revenues received in respect of any of the Assets prior to August 1, 1996 pursuant to an operating agreement is referred to herein as an "Audit Notice".

Neither the Purchaser nor the Company shall make a payment by way of an adjustment resulting from any such Joint Venture Audit, of expenses or revenues pertaining to any period ending on or prior to August 1, 1996, without the consent of the Representative acting reasonably, except pursuant to the award of a Court or arbitrator. Subject to Sections 5.1, 9.1 and 9.2, if the amount of the payment to be made or received by the Company, as the case may be, exceeds $100,000, the Vendors shall forthwith reimburse the Company for, or the Purchaser shall cause the Company to pay to the Representative (for immediate disbursement to the Vendors as their interests appear), as the case may be, the amount by which the said payment exceeds $100,000.

(b) Upon notice given by the Representative to the Purchaser within 15 Business Days after receipt by the Representative from the Purchaser or the Company of a notice of an Assessment, the Representative on behalf of the Vendors shall have the right at its own expense (not to be paid out of the Escrow Account) and employing counsel of its own choice to contest, in good faith, any Assessment. In such event, the Purchaser shall have the right to retain its own counsel but the fees and expenses of such counsel shall be at the expense of the Purchaser. The failure to give such notice of intent to contest an Assessment shall constitute a waiver of the Vendors' right to contest such Assessment under this Section 9.6(b) and shall preclude the Vendors from disputing the manner in which the Purchaser or the Company may in good faith contest such Assessment or the reasonableness of any amount paid in good faith by the Company in satisfaction of such Assessment. The Representative shall not compromise or settle any Assessment without the consent of the Purchaser, which shall not be unreasonably withheld. (c) The Purchaser will cooperate with the Representative, including providing access to its employees and to financial and other records of the Company and the Purchaser, in order to facilitate the filing of Tax Returns or returns relating to Alberta Crown Royalties, as the case may be, in respect of periods of time prior to the Closing and the conduct of any disputes relating thereto.

(d) Except with the consent of the Representative, which consent shall not be unreasonably withheld, the Purchaser shall not, and shall not permit the Company, to agree to any compromise or settlement with respect to any Assessment; provided, however, that notwithstanding the foregoing, if the Purchaser or the Company determines in good faith that the failure to pay, compromise or settle an Assessment could adversely affect the Company or its business, the Purchaser or Company may pay, compromise or settle such Assessment and such action shall not impair or adversely affect the Purchaser's or Company's right to make such payment the subject of a claim in accordance with Sections 9.1, 9.2 and 9.6 hereof. (e) If a refund of Taxes or Alberta Crown Royalties, as the case may be (to the extent not reflected in the July 31 Balance Sheet) (the "Refund") is received by, or credited to, the account of the Company, in respect of any fiscal period ending on or prior to July 31, 1996, such recipient shall pay the amount of the Refund to the Representative, after deduction of an amount equal to the amount of Taxes, if any, to which the recipient would be subject as a result of the receipt or crediting of such Refund. The Representative shall forthwith upon receipt of any such Refund distribute same to the Vendors as their respective interests appear. (f) The Purchaser undertakes to inform and to cause the Company to inform the Representative of all written audit inquiries received with respect to the representations and warranties in Section 3.9 within 30 days of receipt thereof and to provide the Representative with the right to make any representations prior to an Assessment. (g) References to the "Company" in this Section 9.6 shall include and be deemed to include successors to such corporations by way of amalgamation, winding-up or other reorganization of any nature whatsoever. (h) The failure by the Purchaser to give to the Representative the notice required by Section 9.6(a) with, respect to any Claim relating to Tax or Alberta Crown Royalty matters shall relieve the Vendors of their obligations with respect to such Claim only in the event the Vendors are prejudiced by such failure. (i) Notwithstanding any of the provisions of this Agreement, the Purchaser shall not be entitled to recover twice for the same Damages or Claim under Section 9.2 in respect of the breach or incorrectness of any of the representations and warranties set forth in Article 3 or in respect of any amount of Taxes or Alberta Crown Royalties. 9.7 Repayment of Debentures On the same Business Day as the Representative makes written demand of the Company, which shall not be made earlier than the Business Day immediately after Closing, the Purchaser shall cause the Company to repay in full the principal amount of the Debentures, plus the interest accrued but unpaid thereon, to the Vendors, as their respective interests appear.

In connection with the consummation of the Bond Offering (as defined herein) the Borrower has paid contemporaneously with the effectiveness of this Agreement all amounts outstanding under the Original Credit Agreement. D. The Borrower, the Agent and the Banks desire to amend and restate the Original Credit Agreement in its entirety, to provide for among other things, the modification, extension and renewal of the "Revolving Commitments" under the Original Credit Agreement, which are the Commitments referred to herein. Accordingly, in consideration of the foregoing and the mutual covenants set forth herein, the parties agree that the Original Credit Agreement is hereby amended and restated in its entirety to read as follows: HOU04:43581.4 ARTICLE I DEFINITIONS, ETC. Section 1.01. Certain Defined Terms. Capitalized terms used in this Agreement and not otherwise defined herein, shall have the respective meanings set forth in Annex A hereto (such meanings to be equally applicable to both singular and plural forms of the terms defined).

No provision of this Agreement shall be interpreted or construed against any Person solely because that Person or its legal representative drafted such provision. HOU04:43581.4 ARTICLE II COMMITMENTS AND TERMS OF CREDIT Section 2.01. Commitments. (a) (i) Each Bank severally agrees, on the terms and conditions hereinafter set forth, to make one or more loans (the "Loans") to the Borrower from time to time on any Business Day during the period from the Effective Date up to, but excluding, the Maturity Date in an aggregate amount outstanding for such Bank not to exceed at any time an amount equal to such Bank's Commitment. Each Loan shall be made as either a Base Rate Loan or a Eurodollar Rate Loan and as part of a single Borrowing made on the same day by the Banks ratably according to their respective Commitment Percentages. Each Base Rate Borrowing shall be in an aggregate amount not less than $2,000,000, or, if less, the entire unfunded portion of the Total Commitment. Each Eurodollar Rate Borrowing shall be in an aggregate amount not less than $2,000,000 or an integral multiple of $1,000,000 in excess thereof. Within the limits set forth above and subject to the terms and conditions of this Agreement, the Borrower may borrow, repay pursuant to Section 2.07 or prepay pursuant to Section 2.09 and reborrow under this Section 2.01(a). (ii) The Issuing Bank agrees, on the terms and conditions hereinafter set forth, to issue standby or commercial letters of credit for the account of the Borrower (the "Letters of Credit") from time to time on any one or more Business Days during the period from the Effective Date up to, but excluding, the ninetieth (90th) day preceding the Maturity Date in an aggregate amount for all Outstanding Letters of Credit not exceeding at any time the Letter of Credit Limit. Each Letter of Credit shall be denominated in Dollars, shall expire no later than the date set forth in Section 2.03(a), and shall be in such form as approved from time to time by the Issuing Bank and the Borrower. Each Bank severally agrees, on the terms and conditions hereinafter set forth, to purchase participations in the Letters of Credit issued by the Issuing Bank pursuant to this Agreement in an amount equal to such Bank's Commitment Percentage of the face amount of such Letter of Credit. Upon the issuance of each Letter of Credit, the Issuing Bank shall be deemed, without further action by any party hereto, to have sold to each Bank, and each Bank shall be deemed, without further action by any party hereto, to have purchased from the Issuing Bank, a participation, to the extent of such Bank's Commitment Percentage, in such Letter of Credit, the obligations of the Issuing Bank thereunder and in the reimbursement obligations of the Borrower due in respect of drawings made under such Letter of Credit. Subject to the terms of the Loan Documents, the Banks will execute any other documents the Issuing Bank may reasonably request to evidence the purchase of such participation. On each day during the period commencing with the issuance by the Issuing Bank of any Letter of Credit and ending on the date when such Letter of Credit shall have expired or been terminated, and, irrespective of whether such Letter of Credit has expired or terminated if such Letter of Credit has been drawn upon and the amount so drawn has not been reimbursed to the Issuing Bank, the Commitment of each Bank shall be deemed to be utilized for all purposes hereof in an amount equal to such Bank's Commitment Percentage of the Outstanding Letters of Credit. HOU04:43581.4 (iii) Notwithstanding any other term or provision hereof (A) no Loan shall be made and no Letter of Credit shall be issued if after giving effect to the making of such Loan or issuance of such Letter of Credit the aggregate amount of Credit Outstanding would exceed the Total Commitment and (B) no Letter of Credit shall be issued if after giving effect to the issuance of such Letter of Credit the aggregate amount of Outstanding Letters of Credit would exceed the Letter of Credit Limit. (b) Loans of more than one Type may be outstanding at the same time, but the Borrower shall not be entitled to request any Borrowing or to Convert Loans comprising any Borrowing into Loans of another Type, if after giving effect to such Borrowing or Conversion, as the case may be, any Bank would have outstanding (i) at any one time more than four (4) different Types of Loans. Loans having different Interest Periods, regardless of whether they commence on the same date or have the same type of interest rate, shall be considered different Types of Loans; provided, however, that all Base Rate Loans are the same type of Loan so long as they remain Base Rate Loans. Section 2.02. Borrowing Procedures; Conversions. (a) (i) Each Borrowing shall be made upon the written, telecopied or facsimile transmitted request of the Borrower, given to the Agent not later than 11:00 a.m. (New York time) on (A) the third Business Day prior to the proposed Borrowing Date in the case of a Eurodollar Rate Borrowing, or (B) the Business Day immediately preceding the proposed Borrowing Date in the case of a Base Rate Borrowing, and the Agent shall give each other member of the Bank Group prompt notice of such request by telecopier, telex or cable. (ii) Each request for a Borrowing (a "Borrowing Request") made by the Borrower shall be in substantially the form of Exhibit 2.02(a), specifying therein (A) the Borrowing Date for such Borrowing, (B) the Type of Loans comprising such Borrowing, (C) the aggregate amount of such Borrowing and (D) in the case of a Eurodollar Rate Borrowing, the Interest Period for the Loans comprising such Borrowing. Each Bank shall, before 12:00 Noon (New York time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 9.03, in same day funds, such Bank's ratable portion of such Borrowing. After the Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will make such funds available to the Borrower at the Agent's aforesaid address. Each Borrowing Request shall be irrevocable and binding on the Borrower. (b) Unless the Agent shall have received notice from a Bank prior to the date of any Borrowing that such Bank will not make available to the Agent such Bank's ratable portion of such Borrowing, the Agent may assume that such Bank has made such portion available to the Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have HOU04:43581.4 so made such ratable portion available to the Agent, such Bank and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount, together with interest thereon for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank's Loan as part of such Borrowing for purposes of this Agreement, and Borrower shall be relieved of Borrower's obligation to repay such amount under this Section 2.02(b). The failure of any Bank to make the Loan to be made by it as part of any Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its Loan on the date of such Borrowing or any subsequent Borrowing Date, but no Bank shall be responsible for the failure of any other Bank to make the Loan to be made by such other Bank on the date of any Borrowing. (c) The Borrower may, subject to the terms of this Agreement, on any Business Day, upon written, telecopied or facsimile transmitted notice to the Agent, given not later than 11:00 a.m. (New York time) on (i) the third Business Day prior to the proposed Conversion Date in the case of a Conversion of Loans into Eurodollar Rate Loans, or (ii) the Business Day immediately preceding the proposed Conversion Date in the case of a Conversion of Loans into Base Rate Loans, Convert Loans into Borrowings comprised of Loans of another Type, and the Agent shall promptly transmit the contents of such notice to each other member of the Bank Group by telecopier, telex or cable. Notwithstanding any other term or provision hereof, after giving effect to any such Conversion, the size of all Borrowings outstanding hereunder, and the number of different Types of Loans outstanding hereunder, shall conform to the requirements of Section 2.01. In the event of any Conversion of Eurodollar Rate Loans on any day other than the last day of the Interest Period applicable thereto, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.13. Each notice of a Conversion (a "Conversion Notice") given by the Borrower shall be in substantially the form of Exhibit 2.02(c) hereto, specifying therein (A) the Conversion Date for such Conversion, (B) the Loans to be Converted, (C) the Type of Loans to which such Loans are to be Converted and (D) in the case of a Conversion into Eurodollar Rate Loans, the Interest Period for such Converted Loans. If the Borrower shall fail to give a timely Conversion Notice conforming to the requirements of this Agreement with respect to any Eurodollar Rate Loans prior to the expiration of the Interest Period applicable thereto, such Eurodollar Rate Loans shall, automatically on the last day of such Interest Period, be Converted into Base Rate Loans. Section 2.03. Issuing and Reimbursing the Letters of Credit. (a) Each Letter of Credit shall, subject to the terms of this Agreement, be issued upon the written or facsimile transmitted request (an original of which shall be immediately forwarded by overnight courier to the Issuing Bank) of the Borrower given to the Agent not later than 11:00 a.m. (New York time) on the third Business Day prior to the proposed date of issuance of such Letter of HOU04:43581.4 Credit. Each such request for a Letter of Credit (a "Letter of Credit Request") made by the Borrower shall be in substantially the form of Exhibit 2.03 hereto and shall specify the Business Day on which such Letter of Credit is to be issued, the beneficiary of such Letter of Credit, the amount of such Letter of Credit, the draw conditions applicable thereto and shall provide for an expiry date which is not later than thirty days prior to the Maturity Date. (b) Upon satisfaction of the applicable terms and conditions set forth in Article III, the Issuing Bank shall issue such Letter of Credit to the specified beneficiary not later than the close of business (New York time) on the date so specified. The Issuing Bank shall provide each other member of the Bank Group with a copy of each Letter of Credit so issued, but any failure of the Issuing Bank to provide such Persons with a copy of such Letter of Credit shall not in any way affect the Borrower's obligation to reimburse the Issuing Bank for any amount paid by the Issuing Bank under any Letter of Credit or the Banks' obligation to reimburse the Issuing Bank for such amount, to the extent provided herein, in the event the Borrower fails to do so. Each such Letter of Credit shall (i) provide for the payment of drafts or other forms of payment to be presented for honor thereunder by the beneficiary in accordance with the terms thereon, at sight when accompanied by the documents described therein and (ii) be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, (and any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Bank) (the "UCP") and shall, as to matters not governed by the UCP, be governed by, and construed and interpreted in accordance with, the governing law specified in this Agreement. (c) Upon presentment to the Issuing Bank of any draft for honor under any Letter of Credit by the beneficiary thereof and the determination by the Issuing Bank that such draft is in order, the Issuing Bank shall give prompt notice (a "Reimbursement Notice") to the Borrower of (i) the Letter of Credit to which such Reimbursement Notice relates, (ii) the amounts to be paid on account of such draft (the "Reimbursement Amount") and (iii) the date on which such amounts are to be paid (the "Reimbursement Date"), but any failure to so notify the Borrower shall not in any way affect the Borrower's obligations to reimburse the Issuing Bank for any amount paid by the Issuing Bank under any Letter of Credit. (d) Upon receipt of any Reimbursement Notice, the Borrower shall reimburse the Issuing Bank by forthwith paying to the Agent for the benefit of the Issuing Bank (who shall promptly notify the Issuing Bank of such payment) no later than 10:00 a.m. (New York time) on the Reimbursement Date specified in such Reimbursement Notice an amount equal to the Reimbursement Amount specified in such Reimbursement Notice, and, if the Issuing Bank is not fully reimbursed by the Borrower on such Reimbursement Date, together with interest from such Reimbursement Date until such reimbursement is made by the Borrower at a fluctuating rate per annum equal to the lesser of (i) the Highest Lawful Rate and (ii) the Base Rate in effect during the time such reimbursement HOU04:43581.4 obligation remains unpaid plus the Applicable Margin for Base Rate Loans from such Reimbursement Date until the third day immediately following the delivery of such Reimbursement Notice by the Issuing Bank to Borrower and (B) thereafter, the Default Rate. To the extent availability may then exist, and upon compliance with the relevant terms and conditions of this Agreement, the Borrower may repay any or all of the obligations described in this paragraph by requesting a Borrowing and applying the proceeds thereof accordingly. (e) If the Borrower shall fail to reimburse the Issuing Bank for any payment by the Issuing Bank under a Letter of Credit by 12:00 noon. (New York time) on the Reimbursement Date specified in the Reimbursement Notice related thereto, the Agent shall give prompt notice thereof to each other member of the Bank Group. Upon receipt of such notice, each Bank shall, notwithstanding any other provision of this Agreement (including the occurrence and continuance of a Default or an Event of Default), make available to the Agent for the benefit of the Issuing Bank an amount equal to its Commitment Percentage of the Reimbursement Amount specified in the related Reimbursement Notice no later than the close of business on such Reimbursement Date. If such amount is not in fact made available to the Agent by such Bank on such Reimbursement Date, such Bank shall pay to the Agent for the account of the Issuing Bank, on demand made by the Issuing Bank, in addition to such amount, interest on such amount for the number of days that elapse from such Reimbursement Date to the date on which the amount equal to such Bank's Commitment Percentage of such Reimbursement Amount becomes immediately available to the Issuing Bank at a rate per annum equal to the average daily Federal Funds Rate for such days. Any amount received by the Agent or the Issuing Bank from the Borrower in respect of a draft honored under a Letter of Credit after one or more of the Banks have made funds available for the payment of such draft pursuant to this paragraph shall be paid over by the Agent or the Issuing Bank, as the case may be, to the Banks, pro rata according to the amounts so made available by the Banks, promptly upon receipt by the Agent or the Issuing Bank of such amount. Nothing in this Agreement shall diminish the Borrower's obligation under this Agreement to provide the funds for the payment of, or on demand to reimburse the Issuing Bank for payment of, any draft presented to, and duly honored by, the Issuing Bank under any Letter of Credit. (f) In order to induce the issuance of Letters of Credit by the Issuing Bank and the purchase of participations therein by the Banks, the Borrower irrevocably agrees (i) that the obligation of the Borrower to reimburse the Issuing Bank for amounts paid by the Issuing Bank under any Letter of Credit, including accrued interest thereon, as set forth herein is absolute and unconditional, (ii) that no member of the Bank Group shall be responsible or liable for, and the Borrower's unconditional obligation to reimburse the Issuing Bank through the Agent for amounts paid by the Issuing Bank on account of drafts honored under the Letters of Credit shall not be affected by, any circumstance, act or omission whatsoever relating to any Letter of Credit, whether or not known to any member of the Bank Group, unless such circumstance, act or omission results in the wrongful payment or the wrongful dishonor of any Letter of Credit HOU04:43581.4 or is otherwise the result of the gross negligence or willful misconduct of such member of the Bank Group, (iii) that any action taken or omitted to be taken by any member of the Bank Group under or in connection with any Letter of Credit or any related draft, document or property shall be binding on the Borrower and shall not put any member of the Bank Group under any resulting liability to the Borrower, unless such action or omission results in the wrongful payment or the wrongful dishonor of any Letter of Credit or otherwise is the result of the gross negligence or willful misconduct of such member of the Bank Group and (iv) to indemnify, defend and hold each member of the Bank Group harmless from and against any and all liabilities, damages, claims or reasonable expenses (including reasonable attorneys' fees and amounts paid in settlement) arising out of or based on any Letter of Credit, except to the extent the same is the result of the wrongful payment or the wrongful dishonor of any Letter of Credit or is otherwise the result of the gross negligence or willful misconduct of the Person seeking indemnity hereunder, IT BEING THE EXPRESS INTENTION OF THE BORROWER THAT EACH MEMBER OF THE BANK GROUP SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LIABILITIES, CLAIMS, OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF SUCH MEMBER OF THE BANK GROUP. The Borrower hereby waives presentment for payment and notice of dishonor, protest and notice of protest with respect to drafts honored under the Letters of Credit. (g) The provisions of this Agreement and the other Loan Documents concerning collateral, standard of care of the Issuing Bank, timing of payments, interest rates applicable to any reimbursement obligation relating to any Letter of Credit, any representations, warranties, covenants, events of default, remedies and governing law shall supersede in their entirety the provisions of any Letter of Credit application relating to such matters. In the event any other provision of any Letter of Credit application is inconsistent with, or in conflict of any provision of this Agreement or any Loan Documents, the provisions of this Agreement or the Loan Documents shall govern. Section 2.04. Borrowing Base. (a) The Borrowing Base in effect from time to time shall represent the maximum amount (subject to the Total Commitment) of Loans that the Banks will make to the Borrower. During the period from and after the Effective Date until the Borrowing Base is redetermined in accordance with this Section, the amount of the Borrowing Base shall be $20,000,000. The Borrowing Base shall be determined in accordance with Section 2.04(b) by the Agent and approved by all of the Banks or the Majority Banks, as applicable. The Borrowing Base is subject to redetermination in accordance with Section 2.04(d). Upon any redetermination of the Borrowing Base, such redetermination shall remain in effect until the next successive date that the redetermined Borrowing Base becomes effective subject to the notice requirements specified in Section 2.04(e) for both the scheduled redetermination and unscheduled redeterminations. So long as any part of the Commitments are in effect and until all of the Loans outstanding hereunder are paid in full, this Agreement shall be governed by the then effective Borrowing Base. HOU04:43581.4 (b) The Agent will after receipt of the most recent Reserve Report delivered to the Banks under Section 5.10, and such other data and supplemental information as may from time to time be reasonably requested by the Agent, but in no event later than May 1 and November 1 of each year commencing May 1, 1997, redetermine the Borrowing Base based on such Reserve Report. The Agent and each Bank will redetermine the Borrowing Base in accordance with their respective normal and customary oil and gas lending criteria as such exist at that particular time taking into account all of the assets and liabilities of the Borrower and its Subsidiaries. The Agent and each Bank, in their sole discretion, may make reasonable adjustments to the rates, volumes and prices and other assumptions set forth in the Reserve Reports and such other data and supplemental information. Each redetermination of the Borrowing Base which would increase the Borrowing Base must be approved by all of the Banks, and each other redetermination of the Borrowing Base must be approved by the Majority Banks. Failure of a Bank to object to a redetermination within 14 days after notice of such redetermination is given to such Bank by the Agent shall be deemed an approval of such redetermination by such Bank. (c) The Agent may exclude any Oil and Gas Property or portion of production therefrom from the Borrowing Base, at any time, because the status of title to such Oil or Gas Property is not reasonably satisfactory to Agent or because such Oil and Gas Property is not subject to a first priority lien in favor of the Agent as security for the Obligations. (d) So long as any of the Commitments are in effect and until payment in full of all Loans hereunder, effective on or about May 1 and November 1 of each year commencing May 1, 1997 (each being a "Scheduled Redetermination Date"), the Agent with the approval of all of the Banks or the Majority Banks, as applicable, shall redetermine the amount of the Borrowing Base in accordance with Section 2.04(b). In addition, at any time after the first scheduled Redetermination Date, (i) the Borrower may request a redetermination of the Borrowing Base on its own initiation at any time in connection with a proposed acquisition of Oil and Gas Properties with a fair market value in excess of $10,000,000 and at one additional time during any consecutive twelve (12) month period, and (ii) the Agent and Majority Banks may each initiate a redetermination of the Borrowing Base at any time as they so elect; provided, however, that the Agent and Majority Banks may each initiate only one such unscheduled redetermination during any consecutive twelve (12) month period (each being an "Unscheduled Redetermination Date"). Any redetermination of the Borrowing Base on an Unscheduled Redetermination Date shall be in accordance with Section 2.04(b). (e) The Agent shall promptly notify in writing the Borrower and the Banks of the new Borrowing Base. Such redetermination of the Borrowing Base shall not be in effect until notice is given to the Borrower. HOU04:43581.4 Section 2.05. The Notes. The Loans made by each Bank shall be evidenced by a single Note issued to such Bank by the Borrower, (i) dated the date of this Agreement (or such other date as may be specified in Section 9.02), (ii) payable to the order of such Bank in a principal amount equal to such Bank's Commitment Percentage of the Aggregate Maximum Commitment and (iii) otherwise duly completed. Each Loan made by a Bank to the Borrower and all payments made on account of the principal amount thereof shall be entered by such Bank in its records or on the schedule (or a continuation thereof) attached to the Note of such Bank, provided, that prior to any transfer of any such Note, such Bank shall endorse the amount and maturity of any outstanding Loans on the schedule (or a continuation thereof) attached to such Note. Section 2.06. Reduction of the Commitments. (a) The Borrower shall have the right, upon at least three Business Days' notice to the Agent to terminate in whole or reduce ratably in part the unused portions of the Aggregate Maximum Commitment; provided, that each partial reduction in the Aggregate Maximum Commitment shall be in the aggregate amount of $1,000,000 or an integral multiple of $1,000,000 in excess thereof. Any such reduction or termination shall be irrevocable by the Borrower. (b) On each Commitment Reduction Date, the Reducing Commitment Amount shall automatically be reduced by an amount equal to 8.2% of the Reducing Commitment Amount as of the first Commitment Reduction Date. On the Maturity Date the Commitment of each Bank shall automatically be reduced to zero. Section 2.07. Mandatory Repayment of Loans. (a) The Borrower shall from time to time repay the Loans comprising part of the same Borrowing or provide cover for Outstanding Letters of Credit in such amounts as shall be necessary so that at all times the Credit Outstanding shall not be in excess of the Total Commitment. Except to the extent that repayment or cover is required to be made in three equal monthly installments under Section 2.07(b), any repayment or cover required by this Section 2.07(a) shall be due and payable on the date such repayment or cover obligation accrues pursuant to the preceding sentence. (b) The Borrower shall from time to time repay the Loans comprising part of the same Borrowing or provide cover for Outstanding Letters of Credit (as provided below) in whole or ratably in part in an amount equal to the excess of (i) the Credit Outstanding as of any redetermination of the Borrowing Base pursuant to Section 2.04 over (ii) the Borrowing Base as of such date. Any repayment or cover required by this Section 2.07(b) shall be due and payable in three equal monthly installments, each in an amount equal to one third (1/3rd) of the original amount of such excess, commencing on the last day of the calendar month immediately following such redetermination of the Borrowing Base and continuing on the same day of each subsequent calendar month. HOU04:43581.4 (c) In the event that the Borrower shall be required pursuant to this Section 2.07 to repay Loans or provide cover for Outstanding Letters of Credit, the Borrower shall make such repayment and provide such cover in the following order: (i) first, pay the amount of all unreimbursed drawings under the Letters of Credit, (ii) second, repay the principal of the Loans and (iii) third, provide cover for Letters of Credit. Cover for Letters of Credit shall be effected by paying to the Agent immediately available funds, to be held by the Agent in an account under the sole dominion and control of the Agent, for the benefit of the Bank Group, as security for the obligations of the Borrower under the Loan Documents until the earlier of (A) the occurrence in this Section 2.07 which necessitated such cover no longer exists or (B) such time as the Letters of Credit have been terminated and all obligations of the Borrower to the Bank Group (including the Issuing Bank) in respect thereof have been paid in full, at which time the Agent shall remit the amount of such cover, in immediately available funds, at the direction or instruction of the Borrower. Any funds delivered pursuant to the preceding sentence shall be placed in an interest bearing account selected by the Agent and so long as no Default has occurred and is continuing, any accrued interest on such funds shall be distributed monthly to the Borrower. (d) All outstanding Loans shall be fully due and payable on the Maturity Date, together with any unpaid interest accrued thereon. (e) Each repayment of Loans required by this Section 2.07 shall be accompanied by payment of accrued interest to the date of such payment on the principal amount paid. In the event of any payment of a Eurodollar Rate Loan, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.13. All principal payments required by this Section 2.07 shall first be applied to Base Rate Borrowings, and second to Eurodollar Rate Borrowings. Section 2.08. Interest Accrual, Payments. (a) Accrual and Payment. Subject to the provisions of Section 9.13, the Borrower shall pay interest on the unpaid principal amount of each Loan made by each Bank from the date of such Loan until such principal amount shall be paid in full, on the dates and at the rates per annum specified as follows: (i) Base Rate Loans. If such Loan is a Base Rate Loan, a rate per annum equal at all times to the lesser of (A) the Highest Lawful Rate and (B) the Base Rate in effect from time to time plus the Applicable Margin in effect from time to time, and unpaid accrued interest on such Loans shall be due and payable on each Quarterly Payment Date and on the date such Base Rate Loan shall be paid in full; provided, however, that if the Borrower has not been notified by the Agent of the amount of such accrued interest at least one Business Day prior to such date, such accrued interest shall be due and payable one Business Day after the Borrower is notified of such amount. (ii) Eurodollar Rate Loans. If such Loan is a Eurodollar Rate Loan, a rate per annum equal at HOU04:43581.4 all times during the Interest Period for such Loan to the lesser of (A) the Highest Lawful Rate and (B) the sum of the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect as of the first day of such Interest Period, and unpaid accrued interest on such Loans shall be due and payable on the last day of such Interest Period; provided, however, that if the Borrower has not been notified by the Agent of the amount of such accrued interest at least one Business Day prior to such date, such accrued interest shall be due and payable one Business Day after the Borrower is notified of such amount. Any amount of principal or, to the extent permitted by applicable law, interest which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, at a rate per annum equal at all times to the lesser of (A) the Highest Lawful Rate and (B) the Base Rate in effect from time to time during the applicable period plus the Applicable Margin in effect from time to time during such period plus two percent (2%) (the "Default Rate"), payable on demand. (b) Determination of Interest Rates. (i) The Agent shall give prompt notice to the Borrower and each other member of the Bank Group of the applicable interest rate determined by the Agent hereunder for each Borrowing. Each determination by the Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error. (ii) If the Majority Banks shall, at least one Business Day before the date of any requested Eurodollar Rate Borrowing, notify the Agent that the Eurodollar Rate applicable to such Borrowing will not adequately reflect the cost to such Banks of making, funding or maintaining their respective Eurodollar Rate Loans for such Borrowing, the right of the Borrower to select Eurodollar Rate Loans for such Borrowing or any subsequent Borrowing shall be suspended until the Agent shall notify the Borrower and each other member of the Bank Group that the circumstances causing such suspension no longer exist, and each Loan comprising such Borrowing shall be made as, or Converted into, as applicable, a Base Rate Loan. (c) Applicable Margin. As used in this Agreement and the other Loan Documents, "Applicable Margin" means, as to Loans consisting of a single Borrowing, a rate per annum determined by reference to the Type of Loans comprising such Borrowing as follows: (i) if the aggregate amount of Loans outstanding as of the date of determination is equal to or greater than 66.7% of the Total Commitment as of such date, then such rate per annum shall be one-half of one percent (1/2%) for Base Rate Loans, and two percent (2%) for Eurodollar Rate Loans; (ii) if the aggregate amount of Loans outstanding as HOU04:43581.4 of the date of determination is equal to or greater than 33.3% but less than 66.7% of the Total Commitment as of such date, such rate per annum shall be one-half of one percent (1/2%) for Base Rate Loans and one and three-quarters (1 3/4%) for Eurodollar Rate Loans; and (iii) if the aggregate amount of Loans outstanding as of the date of determination is less than 33.3% of the Total Commitment as of such date, such rate per annum shall be one-half of one percent (1/2%) for Base Rate Loans, and one and one-quarter percent (1 1/4%) for Eurodollar Rate Loans. Section 2.09. Optional Prepayments. (a) The Borrower may, from time to time on any Business Day, upon notice to the Agent stating the proposed date and aggregate principal amount thereof, and if such notice is given the Borrower shall, prepay the outstanding principal amount of the Base Rate Loans (without premium or penalty) comprising part of the same Borrowing in whole or ratably in part; provided, that any partial prepayment of such Base Rate Loans shall be in an aggregate principal amount of not less than $500,000. The Borrower may from time to time upon at least three Business Days' notice to the Agent stating the proposed date and the aggregate principal amount thereof, and if such notice is given the Borrower shall, prepay the outstanding principal amount of the Eurodollar Rate Loans comprising part of the same Borrowing in whole or ratably in part; provided, that any partial prepayment of such Eurodollar Rate Loans shall be in an aggregate principal amount of not less than $500,000 or an integral multiple of $100,000 in excess thereof. (b) Each prepayment of Loans made pursuant to this Section 2.09 shall be accompanied by a payment of accrued interest to the date of such prepayment on the principal amount prepaid. In the event of any prepayment of a Eurodollar Rate Loan, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.13. Section 2.10. Payments, Notice of Certain Repayments and Computations. (a) All payments of principal, interest, commitment fees and other amounts hereunder, under the Notes and the other Loan Documents (other than Bank Group Derivatives) shall be made in Dollars to the Agent at its address specified in Section 9.03 for the account of each of the Banks, in immediately available funds not later than 11:00 a.m. (New York time) on the date when due. Upon receipt of such payments, the Agent will promptly cause to be distributed like funds relating to the payment of principal or interest or commitment fees ratably (other than amounts payable pursuant to Section 2.12, Section 2.13, Section 2.14 or Section 2.15) to the Banks, for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank, to such Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. (b) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks under the HOU04:43581.4 Loan Documents that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent the Borrower shall not have made such payment in full to the Agent each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank, together with interest thereon for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent at the Federal Funds Rate. (c) All payments by the Borrower of the fees payable to the Agent or the Issuing Bank shall be made in Dollars directly to such Person at its address specified in Section 9.03 in immediately available funds not later than 11:00 a.m. (New York time) on the date when due. (d) All computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate, as well as commitment fees, shall be made on the basis of a year of 360 days (unless use of a 360 day year would cause the interest contracted for, charged or received hereunder to exceed the Highest Lawful Rate, in which case such computations shall be made on the basis of a year of 365 or 366 days, as the case may be), in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or commitment fees are payable. (e) Whenever any payment under the Loan Documents shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment fee, as the case may be; provided, if such extension would cause payment of interest on or principal of Eurodollar Rate Loans to be made in the next following calendar month, such payment shall be made on the immediately preceding Business Day. (f) If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of setoff, or otherwise) on account of the Loans made by it (other than pursuant to Section 2.08(b), Section 2.12, Section 2.13, Section 2.14 or Section 2.15), or payments by the Issuing Bank made pursuant to Section 2.03, in excess of its ratable share of payments on account of the Loans or payments by the Issuing Bank made pursuant to Section 2.03, obtained by all the Banks, such Bank shall forthwith purchase from the other Banks such participations in the Loans made by such other Banks, or the reimbursement obligations in respect of the payments by the Issuing Bank made pursuant to Section 2.03, as the case may be, as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.10(f) may, to the fullest extent HOU04:43581.4 permitted by law and this Agreement, exercise all its rights of payment (including the right of setoff) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation. Section 2.11. Fees. (a) Subject to the provisions of Section 9.13, the Borrower agrees to pay to each Bank a commitment fee equal to one-half of one percent (1/2%) per annum on the average unused portion of the Commitment of such Bank in effect from time to time for the period from the Execution Date to, but excluding, the Maturity Date (or if earlier, the termination in full of the Commitment). Accrued commitment fees shall be due and payable in arrears on each Quarterly Payment Date in each year, on the date of any reduction or termination of the Commitment of such Bank and on the Maturity Date (or if earlier, the termination in full of the Commitment); provided that if the Borrower has not been notified by Agent of the amount of such fee at least one Business Day prior to any such date, such fee shall be due and payable one Business Day after the Borrower is notified by Agent of such amount, and shall be computed for the period commencing with the day to which such fee was last paid (or, in the case of the first commitment fee payment date, for the period commencing with and including the Execution Date) to the date such fee is due and payable. Subject to the provisions of Section 9.13, so long as any Obligation shall remain outstanding or any Banks shall have any Commitment hereunder the Borrower shall pay the Agent an annual agency fee of $25,000 on the Execution Date and on each anniversary date thereof. (b) (i) The Borrower agrees to pay the Issuing Bank a fee in respect of each Letter of Credit issued for the account of the Borrower (the "L/C Fees"). With respect to each Letter of Credit, Borrower agrees to pay an L/C Fee, for the period from the date of issuance of such Letter of Credit in an amount equal to 1 1/4 % per annum on the outstanding face amount of such Letter of Credit. All L/C Fees shall be paid in immediately available funds and shall based on a 360 day year and actual days elapsed. Accrued L/C Fees for each Letter of Credit shall be due and payable in arrears on each Quarterly Payment Date and on the termination or expiration date of such Letter of Credit (or if earlier, the termination in full of the Commitments). The Issuing Bank shall be entitled to retain, solely for the Issuing Bank's account, .15% per annum as an issuing fee on all Letters of Credit (the "Retained L/C Fees") and pay to the Agent for the pro rata benefit of the Banks all remaining L/C Fees. In addition to the L/C Fees, the Borrower shall pay the Issuing Bank, solely for the Issuing Bank's account, its customary administrative service charges relating to the issuance of, amendment to, payment under and transfer of any Letters of Credit. Such amounts to be due and payable when such services are rendered by the Issuing Bank. (ii) On each Quarterly Payment Date, the Issuing Bank shall pay the aggregate amount of all L/C Fees collected by the Issuing Bank during the quarterly period then ended, net of the amount of any Retained L/C Fees retained by the Issuing Bank for such period, to the Agent. Upon receipt by the Agent, the Agent shall distribute such net amount of L/C Fees to the Banks ratably according to their respective Commitment Percentages. Within ten (10) HOU04:43581.4 Business Days after each Quarterly Payment Date, the Issuing Bank shall give a written report to the other members of the Bank Group specifying the gross amount of all L/C Fees collected by the Issuing Bank during the quarterly period then ended, the amount of all Retained L/C Fees, and the net amount of such L/C Fees delivered to the Agent for distribution to the Banks. Section 2.12. Setoff, Counterclaims and Taxes. (a) All payments of principal, interest, expenses, reimbursements, compensation, commitment fees, L/C Fees, arrangement fees or administration fees and any other amount from time to time due under the Notes, this Agreement or any other Loan Document shall be made by the Borrower without setoff or counterclaim and shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each member of the Bank Group, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such member of the Bank Group is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction of such Bank's Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Loan Document to any member of the Bank Group, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.12) such member of the Bank Group receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. (b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under the Notes or the other Loan Documents or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes or the other Loan Documents (hereinafter referred to as "Other Taxes"). (c) The Borrower will indemnify each member of the Bank Group for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.12) paid, by such member of the Bank Group (whether paid on its own behalf or on behalf of any other member of the Bank Group) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 10 days from the date such member of the Bank Group makes written demand therefor. HOU04:43581.4 (d) Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section 9.03, the original or a certified copy of a receipt evidencing payment thereof. If no Taxes are payable in respect of any payment hereunder or under the Notes or the other Loan Documents, upon the reasonable request of the Agent, the Borrower will furnish to the Agent at its address referred to in Section 9.03, a certificate from each appropriate taxing authority, or an opinion of counsel acceptable to the Agent stating that such payment is exempt from or not subject to Taxes. (e) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.12 shall survive the payment in full of the Credit Outstanding and all other amounts owing under the other Loan Documents. The provisions of this Section 2.12 are in all respects subject to Section 9.13 hereof. (f) Each Bank represents and warrants to the Agent, the Issuing Bank, the Borrower and the Guarantor that such Bank is either (i) a corporation organized under the laws of the United States or a state thereof or (ii) entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement and the other Loan Documents (x) under an applicable provision of a tax convention to which the United States is a party or (y) because it is acting through a branch, agency or office in the United States and any payment to be received by it hereunder is effectively connected with a trade or business in the United States. Upon becoming a party to this Agreement (whether by assignment or as an original signatory hereto), and in any event, from time to time upon the request of the Agent or the Borrower, each Bank which is not a corporation organized under the laws of the United States or any state thereof shall deliver to the Agent and the Borrower such forms, certificates or other instruments as may be required by the Agent in order to establish that such Bank is entitled to complete exemption from United States withholding taxes imposed on or with respect to any payments, including fees, to be made to such Bank under this Agreement and the other Loan Documents. Each Bank also agrees to deliver to the Borrower and the Agent and such other supplemental forms as may at any time be required as a result of the passage of time or changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption from U.S. withholding tax on any payments hereunder; provided, that the circumstances of the Bank at the relevant time and applicable laws permit it to do so. If a Bank determines, as a result of any change in either (1) applicable law, regulation or treaty, or in any official application thereof or (2) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 2.12(f), or that it is required to withdraw or cancel any such form or certificate previously submitted, it shall promptly notify the Borrower and the Agent of such fact. If a Bank is organized under the laws of a jurisdiction outside the United States, and the Borrower and the Agent have not received forms, certificates or other instruments indicating to their satisfaction that all payments to be made to such Bank hereunder or under the Guaranty are not subject to United States withholding tax or the Agent otherwise has reason to believe HOU04:43581.4 that such Bank is subject to U.S. withholding tax, the Borrower and the Guarantor shall withhold taxes from such payments at the applicable statutory rate. Each Bank shall indemnify and hold the Borrower, the Guarantor, the Issuing Bank and the Agent harmless from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by them as a result of either (A) such Bank's failure to submit any form or certificate that it is required to provide pursuant to this Section 2.12(f) or (B) reliance by the Borrower, the Guarantor, the Issuing Bank or the Agent on any such form or certificate which such Bank has provided to them pursuant to this Section 2.12(f). HOU04:43581.4 Section 2.13. Funding Losses. The Borrower shall indemnify each Bank against any loss or reasonable expense (including, but not limited to, any loss or reasonable expense sustained or incurred or to be sustained or incurred in liquidating or reemploying deposits from third parties acquired to effect or maintain such Loan or any part thereof as a Eurodollar Rate Loan) which such Bank may sustain or incur as a consequence of (a) any failure by the Borrower to fulfill on the date of any Borrowing hereunder the applicable conditions set forth in Article III, (b) any failure by the Borrower to borrow hereunder, or to Convert Loans hereunder or to cause a Letter of Credit to be issued after a Borrowing Request, Letter of Credit Request or Conversion Notice, respectively, has been given, (c) any payment, prepayment or Conversion of a Eurodollar Rate Loan required or permitted by any other provisions of this Agreement, including, without limitation, payments made due to the acceleration of the maturity of the Notes pursuant to Section 7.01, or otherwise made on a date other than the last day of the applicable Interest Period, (d) any default in the payment or prepayment of the principal amount of any Loan or any part thereof or interest accrued thereon, as and when due and payable (at the due date thereof, by notice of prepayment or otherwise) or (e) the occurrence of an Event of Default. Such loss or reasonable expense shall include, without limitation, an amount equal to the excess, if any, as determined by each Bank of (i) its cost of obtaining the funds for the Loan being paid, prepaid or Converted or not borrowed or Converted (based on the Eurodollar Rate applicable thereto) for the period from the date of such payment, prepayment or Conversion or failure to borrow or Convert to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow or Convert, the Interest Period for the Loan which would have commenced on the date of such failure to borrow or Convert) over (ii) the amount of interest (as estimated by such Bank) that would be realized by such Bank in reemploying the funds so paid, prepaid or Converted or not borrowed or Converted for such period or Interest Period, as the case may be. A certificate of each Bank setting forth any amount or amounts which such Bank is entitled to receive pursuant to this Section 2.13 shall be delivered to the Borrower (with a copy to the Agent and the Co-Agent) and shall be conclusive, if made in good faith, absent manifest error. The Borrower shall pay to the Agent for the account of each Bank the amount shown as due on any certificate within 10 days after its receipt of the same. Notwithstanding the foregoing, in no event shall any Bank be permitted to receive any compensation hereunder constituting interest in excess of the Highest Lawful Rate. Without prejudice to the survival of any other obligations of the Borrower hereunder, the obligations of the Borrower under this Section 2.13 shall survive the termination of this Agreement and/or the payment or assignment of any of the Notes. Section 2.14. Change of Law. (a) If at any time any Bank determines in good faith (which determination shall be conclusive) that any change in any applicable law, rule or regulation or in the interpretation, application or administration thereof makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for such Bank or its foreign branch or branches to fund or maintain any Eurodollar Rate Loan (any of the foregoing determinations being a "Eurodollar Event"), then, such Bank, at its option, may: (i) declare that Eurodollar Rate Loans will no longer be made HOU04:43581.4 or maintained by such Bank, whereupon the right of the Borrower to select Eurodollar Rate Loans for any Borrowing shall be suspended until such Bank shall notify the Agent that the circumstances causing such Eurodollar Event no longer exist; (ii) with respect to any Eurodollar Rate Loans of such Bank then outstanding, require that all such Eurodollar Rate Loans be Converted to Base Rate Loans, in which event all such Eurodollar Rate Loans shall automatically be Converted into Base Rate Loans on the effective date of such notice and all payments or prepayments of principal that would have otherwise been applied to repay such Converted Eurodollar Rate Loans shall instead be applied to repay the Base Rate Loans resulting from such Conversion; and/or (iii) with respect to any Eurodollar Rate Loans requested of such Bank but not yet made as or Converted into such, require that such Eurodollar Rate Loans be made as or Converted into, as applicable, Base Rate Loans. (b) Upon the occurrence of any Eurodollar Event, and at any time thereafter so long as such Eurodollar Event shall continue, such Bank may exercise its aforesaid option by giving written notice thereof to the Agent and the Borrower, such notice to be effective upon receipt thereof by the Borrower. Any Conversion of any Eurodollar Rate Loan which is required under this Section 2.14 shall be made, together with accrued and unpaid interest and all other amounts payable to such Bank under this Agreement with respect to such Converted Loan (including, without limitation, amounts payable pursuant to Section 2.13 hereof), on the date stated in the notice to the Borrower referred to above. Section 2.15. Increased Costs. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline issued or request made by any central bank or other Governmental Authority (whether or not having the force of law) after the date hereof, there shall be any increase in the cost to any Bank of agreeing to make or making, funding or maintaining Eurodollar Rate Loans, then the Borrower shall from time to time, subject to the provisions of Section 9.13, pay to the Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost upon demand by such Bank. (b) If any Bank shall have determined in good faith that any law, rule, regulation or guideline adopted after the date hereof pursuant to or arising out of the July 1988 report of the Basle Committee on Banking Regulations and Supervisory Practices entitled "International Convergence of Capital Measurement and Capital Standards" or that the adoption after the date hereof of any applicable law, rule, regulation or guideline regarding capital adequacy, or any change after the date hereof in any of the foregoing or in the interpretation or administration thereof by any central bank or other Governmental Authority charged with the interpretation or administration thereof, or compliance by such Bank (or any lending office of such Bank) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority or comparable agency, affects or would affect the amount of capital required or expected to be maintained by such Bank or any corporation controlling such Bank, then the Borrower shall from HOU04:43581.4 time to time, subject to the provisions of Section 9.13, pay to such Bank upon demand additional amounts sufficient to compensate such Bank or such corporation in the light of such circumstances, to the extent that such Bank reasonably determines such increase in capital to be allocable to the existence of such Bank's Commitment hereunder. (c) If any law, executive order or regulation is adopted or interpreted by any central bank or other Governmental Authority so as to affect any of the Borrower's obligations or the compensation to any Bank or the Issuing Bank in respect of the Letters of Credit or the cost to such Bank or the Issuing Bank of establishing and/or maintaining the Letters of Credit (or any participation therein), then the Borrower shall from time to time upon demand, subject to the provisions of Section 9.13, reimburse or indemnify such Bank or the Issuing Bank, as the case may be, with respect thereto so that such Bank or the Issuing Bank, as the case may be, shall be in the same position as if there had been no such adoption or interpretation. (d) Each Bank or the Issuing Bank, as the case may be, will notify the Borrower of any event occurring after the date of this Agreement which will entitle such Bank or the Issuing Bank, as the case may be, to compensation pursuant to this Section 2.15 as promptly as practicable after such Bank obtains knowledge of the occurrence of such event. A certificate of such Bank or the Issuing Bank, as the case may be, setting forth in reasonable detail (i) such amount or amounts as shall be necessary to compensate such Bank (or participating banks or other entities pursuant to Section 9.02) or the Issuing Bank, as the case may be, as specified above and (ii) the calculation of such amount or amounts shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay to such Bank or to the Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after its receipt of the same. The failure of any Bank or the Issuing Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of the right of such Bank, any other Bank or the Issuing Bank, to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital as such rights are set forth herein. The protection of this Section 2.15 shall be available to the Issuing Bank and the Banks regardless of any possible contention of invalidity or inapplicability of law, regulation or condition which shall have been imposed.

ARTICLE IV REPRESENTATIONS AND WARRANTIES In order to induce the Bank Group to enter into this Agreement, the Borrower hereby represents and warrants to the Bank Group as follows: Section 4.01. Corporate Existence. Each of the Borrower and its Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation, and is duly qualified or licensed to transact business as a foreign corporation and is in good standing under the laws of each jurisdiction in which the conduct of its operations or the ownership or leasing of its properties requires such qualification or licensing, except where the failure to be so qualified or licensed will not have a Material Adverse Effect on such Person. Schedule 4.01 is a complete list of the Borrower's Subsidiaries. Section 4.02. Corporate Authority; Binding Obligations. Each of the Borrower and its Subsidiaries has all requisite corporate power and HOU04:43581.4 authority to conduct its business, to own, operate and encumber its Property, and to execute, deliver and perform all of its obligations under the Loan Documents executed by, or to be executed by, such Person. The execution, delivery and performance of each of the Loan Documents to which the Borrower or any of its Subsidiaries is a party and the consummation of the transactions contemplated thereby have been duly authorized by all necessary corporate action. Each of the Loan Documents to which the Borrower or any of its Subsidiaries is a party has been duly executed and delivered by such Person, is in full force and effect and constitutes the legal, valid and binding obligation of such Person, enforceable against it in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditor's rights generally and general principles of equity. The Security Documents create valid Liens in the collateral described therein, securing the secured obligations described therein. Section 4.03. No Conflict. The execution, delivery and performance by the Borrower or any of its Subsidiaries of each Loan Document to which such Person is a party and the consummation of each of the transactions contemplated thereby do not and shall not, by the lapse of time, the giving of notice or otherwise: (a) constitute a violation of any Requirement of Law or a breach of any provision contained in the articles or certificate of incorporation or bylaws of such Person, or any shareholder agreement pertaining to such Person, or contained in any material agreement, instrument or document to which it is now a party or by which it or its properties is bound, except for such violations or breaches that will not have a Material Adverse Effect on any such Person; or (b) result in or require the creation or imposition of any Lien whatsoever upon any of the properties or assets of the Borrower or any of its Subsidiaries (other than Excepted Liens and Liens in favor of the Agent arising pursuant to the Loan Documents). Section 4.04. No Consent. No authorization, consent, approval, license, or exemption of or filing or registration with, any Governmental Authority or any other Person, which has not been obtained, was, is or will be necessary for the valid execution, delivery or performance by the Borrower or any of its Subsidiaries of any of the Loan Documents to which it is a party and the consummation of each of the transactions contemplated thereby or the Borrower's or any of its Subsidiaries' ownership, use or operation of any of their Properties other than (a) those listed on Schedule 4.04 and (b) those that the failure to obtain, file or make will not have a Material Adverse Effect on any such Person. Section 4.05. No Defaults or Violations of Law. No Default or Event of Default has occurred and is continuing. No default (or event or circumstance occurred which, but for the passage of time or the giving of notice, or both, would constitute a default) has occurred and is continuing with respect to any note, indenture, loan agreement, mortgage, lease, deed or other agreement to which the Borrower or any of its Subsidiaries is a party or by which any of them or their Properties is bound, except for such defaults that will not have a Material Adverse Effect on the Borrower or any of its Subsidiaries. Neither the Borrower nor HOU04:43581.4 any of its Subsidiaries is in violation of any applicable Requirement of Law except for such violations that will not have a Material Adverse Effect on any such Person. Section 4.06. Financial Position. (a) Prior to the Execution Date, the Borrower has furnished to the Agent and the Bank Group audited financials of the Borrower and its Subsidiaries as of December 31, 1995 and unaudited financials of the Borrower as of June 30, 1996. The audited financials referred to in the previous sentence have been prepared in accordance with generally accepted accounting principles consistently applied throughout the periods involved and present fairly the financial condition of the Borrower and its Subsidiaries as of the dates thereof and the results of their operations for the periods then ended. No event has occurred since June 30, 1996 that could reasonably be expected to have a Material Adverse Effect on the Borrower or any of its Subsidiaries. (b) Except as fully reflected in the audited financials referred to in paragraph (a) of this Section 4.06, as of the date hereof, there are no liabilities or obligations of the Borrower or any of its Subsidiaries of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether or not due) which, either individually or in aggregate, would have a Material Adverse Effect on the Borrower or any of its Subsidiaries. Section 4.07. Litigation. Except as set out in Schedule 4.07, there are no actions, suits or proceedings pending or, to the knowledge of the Borrower threatened against or affecting the Borrower or any of its Subsidiaries, or the Properties of any such Person, before or by any Governmental Authority or other Person, which, if determined adversely to such Person could have a Material Adverse Effect on any such Person. Section 4.08. Use of Proceeds. (a) The Borrower's uses of the proceeds of the Loans and of the Letters of Credit are, and will continue to be, legal and proper corporate uses (duly authorized by Borrower's board of directors), and such uses are consistent with the terms of the Loan Documents, including, without limitation, Section 5.09, and all Requirements of Law. (b) Neither the Borrower nor any of its Subsidiaries is engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U), and no part of the proceeds of any Loan or Letter of Credit will be used, directly or indirectly, (i) to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying any margin stock or (ii) for the purpose of purchasing, carrying or trading in any securities under such circumstances as to involve the Borrower or any of its Subsidiaries in a violation of Regulation X. Section 4.09. Governmental Regulation. Neither the Borrower nor any of its Subsidiaries is subject to regulation under the Public Utility Holding Company Act, as amended, the Investment Company Act of 1940, as amended, or any other Requirement of Law such that the ability of any such HOU04:43581.4 Person to incur indebtedness is limited or its ability to consummate the transactions contemplated by this Agreement, the other Loan Documents or any document executed in connection therewith is impaired. Section 4.10. Disclosure. The schedules, documents, exhibits, reports, certificates and other written statements and information furnished by or on behalf of the Borrower or any of its Subsidiaries to the Bank Group do not contain any Material misstatement of fact, or omit to state a Material fact necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading. Neither the Borrower nor any of its Subsidiaries has intentionally withheld any fact known to it which has or is reasonably likely to have a Material Adverse Effect on the Borrower or any of its Subsidiaries. Section 4.11. ERISA. (a) The Borrower, and each ERISA Affiliate and Subsidiary have operated and administered each Pension Plan and Other Benefit Plan in compliance with all applicable laws, except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Borrower nor any ERISA Affiliate or Subsidiary has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Internal Revenue Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists or is threatened that could reasonably be expected to result in the incurrence of any such liability by the Borrower or any ERISA Affiliate or Subsidiary, or in the imposition of any Lien on any of the rights, properties or assets of the Borrower or any ERISA Affiliate or Subsidiary, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Internal Revenue Code, other than such liabilities or Liens as would not be, individually or in the aggregate, Material. (b) The present value of the aggregate benefit liabilities under each Pension Plan subject to Title IV of ERISA, determined as of the end of such Pension Plan's most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Pension Plan's most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Pension Plan allocable to such benefit liabilities. The term "benefit liabilities" has the meaning specified in section 4001 of ERISA and the terms "current value" and "present value" have the meaning specified in Section 3 of ERISA. (c) The Borrower and its ERISA Affiliates and Subsidiaries do not currently and have never had any liability or obligation with respect to any liabilities (and are not subject to contingent withdrawal liabilities) under section 4201 or 4204 of any Multiemployer Plan. (d) The expected post-retirement benefit obligation (determined as of the last day of the Borrower's most recently ended fiscal year in accordance with Financial HOU04:43581.4 Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Internal Revenue Code ("COBRA")) of the Borrower and its ERISA Affiliates and Subsidiaries is not Material and, except as modified by COBRA, such obligations can be unilaterally terminated at any time by the Borrower, or its ERISA Affiliates and Subsidiaries without any Material liability. Section 4.12. Payment of Taxes. The Borrower has filed, and has caused each of its Subsidiaries to file, all federal, state and local tax returns and other reports that the Borrower and each such Subsidiary are required by law to file and have paid all taxes and other similar charges that are due and payable pursuant to such returns and reports, except to the extent any of the same may be contested in good faith by appropriate proceedings promptly initiated and diligently conducted, and with respect to which adequate reserves have been set aside on the books of such Person in accordance with generally accepted accounting principles. Section 4.13. Title and Liens. (a) Except as set out in Schedule 4.13 the Borrower and its Subsidiaries have good and defensible title to its Properties, free and clear of all Liens except Liens permitted by Section 6.02. Except as set forth in Schedule 4.13, after giving full effect to the Excepted Liens, the Borrower owns the net interests in production attributable to the Oil and Gas Properties reflected in the Initial Reserve Report and the ownership of such Oil and Gas Properties shall not in any material respect obligate the Borrower to bear the costs and expenses relating to the maintenance, development and operations of each such Oil and Gas Property in an amount in excess of the working interest of each Oil and Gas Property set forth in the Initial Reserve Report. Further, upon delivery of each Reserve Report, the statements made in the preceding sentence shall be true with respect to such furnished Reserve Reports including the ownership of the Oil and Gas Properties set forth therein. To the best of the Borrower's knowledge, all information contained in the Initial Reserve Report is true and correct in all material respects as of the date thereof. (b) All material leases and agreements necessary for the conduct of the business of the Borrower and its Subsidiaries are valid and subsisting, in full force and effect and, to the knowledge of the Borrower, there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which would affect in any material respect the conduct of the business of the Borrower and its Subsidiaries. (c) The rights, properties and other assets presently owned, leased or licensed by the Borrower and its Subsidiaries including, without limitation, all easements and rights of way, include all rights, properties and other assets necessary to permit the Borrower and its Subsidiaries to conduct their business in all material respects in the same manner as their business has been conducted prior to the date hereof. HOU04:43581.4 (d) All of the assets and properties of the Borrower and its Subsidiaries which are reasonably necessary for the operation of its business are in good working condition and are maintained in accordance with prudent business standards. Section 4.14. Gas Imbalances. As of the date of this Agreement, except as set forth in Schedule 4.14 or on the most recent certificate delivered pursuant to Section 5.10(c), on a net basis there are no gas imbalances, take or pay or other prepayments with respect to the Borrower's Oil and Gas Properties which would require the Borrower to deliver Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor exceeding a market value of $100,000 in the aggregate.

If any indemnity furnished to the Agent, the Issuing Bank and the Co-Agent for any purpose is, in the opinion of such Person insufficient or becomes impaired, such Person may call for additional indemnity and not commence or cease to do the acts indemnified against until such additional indemnity is furnished. Without limitation of the foregoing, each Bank agrees to reimburse the Agent, the Issuing Bank or the Co-Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including HOU04:43581.4 counsel fees) incurred by such Person in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and the other Loan Documents, to the extent that the Agent, the Issuing Bank or the Co-Agent is not reimbursed for such expenses by the Borrower.

(c) The Agent shall maintain at its address referred to in Section 9.03 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Banks and the Commitment of, and principal amount of the Loans owing to, each Bank from time to time (the "Register"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower and each member of the Bank Group may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any member of the Bank Group at any reasonable time and from time to time upon reasonable prior notice. (d) Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee representing that it is an Eligible Assignee, together with any Notes subject to such assignment and the administrative fee payable to the Agent for such assignment, the Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit 9.02 hereto, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. Within five (5) Business Days after its receipt of such notice, the Borrower, at its own expense, shall execute and deliver to the Agent, in exchange for the surrendered Notes, new Notes to the order of such Eligible Assignee in an amount corresponding to the Commitment assumed by such Eligible Assignee pursuant to such Assignment and Acceptance and, if the assigning Bank has retained a Commitment hereunder, new Notes to the order of the assigning Bank in an amount corresponding to the Commitment retained by it hereunder. Such new Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form prescribed by Section 2.05 hereto. (e) Each Bank may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment and the Loans owing to it and its interest in the Outstanding Letters of Credit); provided, that (i) such Bank's obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) and the other Loan Documents shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, and the participating banks or other entities shall not be considered a "Bank" for purposes of the Loan Documents, (iii) the participating banks or other entities shall be entitled to the cost protection provisions contained in Sections 2.11 through 2.14 to the same extent that the Bank from HOU04:43581.4 which such participating bank or other entity acquired its participation would be entitled to the benefit of such cost protection provisions, so long as Borrower is not obligated to pay any amount under such Sections in excess of the amount that would have been due to such Bank under such Sections if no participations had been made by such Bank, and (iv) the Borrower and the other members of the Bank Group shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement and the other Loan Documents, and such Bank shall retain the sole right to enforce the obligations of the Borrower relating to the Loans and the Letters of Credit and to approve any amendment, modification or waiver of any provision of this Agreement (other than amendments, modifications or waivers with respect to the amounts of any fees payable hereunder or the amount of principal of or the rate at which interest is payable on the Loans or the amount of any reimbursement obligations payable with respect to any Letter of Credit or the dates fixed for payments of principal or interest on the Loans or reimbursement obligations in respect of any Letters of Credit). (f) Any Bank may at any time pledge or assign all or any portion of its rights under this Agreement and the other Loan Documents to any Federal Reserve Bank without notice to or consent of the Borrower. No such pledge or assignment shall release the assigning Bank from its obligations hereunder. (g) The Agent, the Issuing Bank and each Bank may furnish any information concerning the Borrower or its Subsidiaries in the possession of the Agent or such Bank from time to time to Affiliates of the Agent or such Bank (including without limitation, in the case of Bankers Trust Company, BT Securities Corporation and its employees, to the extent necessary for the purposes contemplated by this Agreement, including, without limitation, the syndication of the credit facilities contemplated hereby) and, in the case of each Bank, to assignees and participants (including prospective assignees and participants) of such Bank. Each Bank will take reasonable steps to protect the confidentiality of any information concerning the Borrower or its Subsidiaries provided to a respective participant or assignee and known by such Bank to be confidential, and, if requested by the Borrower, such Bank will identify the prospective assignees and participants that have received such information.

All correspondence, statements, notices, requests and demands (collectively "Communications") shall be in writing (including telegraphic Communications) and mailed, telegraphed, telecopied, facsimile transmitted or delivered as follows: if to the Borrower -- Abraxas Petroleum Corporation 500 North Loop 1604 East, Suite 100 San Antonio, Texas 78232 Attention: Robert L.G.

Section 9.06. Independence of Covenants. All covenants contained in the Loan Documents shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that such action or condition would be permitted by an exception to, or otherwise be within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default if such action is taken or condition exists. Section 9.07. Survival of Representations and Warranties. All representations and warranties contained in this Agreement and the other Loan Documents or made in writing by the Borrower or the Guarantor in connection herewith or therewith, shall survive the execution and delivery of this Agreement, the Notes and the other Loan Documents, the expiration of the Letters of Credit and the repayment of the Loans. Any investigation by any member of the Bank Group shall not diminish in any respect whatsoever its right to rely on such representations and warranties. Section 9.08. Separability. Should any clause, sentence, paragraph, subsection, Section or Article of this Agreement be judicially declared to be invalid, unenforceable or void, such decision will not have the effect of invalidating or voiding the remainder of this Agreement, and the parties hereto agree that the part or parts of this Agreement so held to be invalid, unenforceable or void will be deemed to have been stricken herefrom by the parties hereto, and the remainder will have the same force and effectiveness as if such stricken part or parts had never been included herein. Section 9.09. Captions. The captions in this Agreement have been inserted for convenience only and shall be given no substantive meaning or significance whatsoever in construing the terms and provisions of this Agreement. Section 9.10. Counterparts.

Section 9.11. Governing Law. THIS AGREEMENT (INCLUDING THE VALIDITY AND ENFORCEABILITY HEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. Chapter 15, Subtitle 3, Title 79, of the Revised Civil Statutes of Texas, 1925, as amended (relating to revolving loans and revolving triparty accounts), shall not apply to this Agreement or the Notes or the transactions contemplated hereby. HOU04:43581.4 Section 9.12. Submission to Jurisdiction. (a) The Borrower hereby irrevocably submits to the non-exclusive jurisdiction of any New York state court located in the Borough of Manhattan, City and State of New York, or any federal court located in the Southern District of New York over any action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents, and each of the Borrower irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such New York state or federal court; provided, nothing in this Section 9.12 is intended to waive the right of any member of the Bank Group to remove any such action or proceeding commenced in any such New York state court to an appropriate New York federal court to the extent the basis for such removal exists under applicable law. The Borrower hereby irrevocably appoints CT Corporation (the "Process Agent"), with an office on the date hereof at 1633 Broadway, New York, New York 10019, as its agent to receive on behalf of it and its properties service of copies of the summons and complaint and any other process which may be served in any such action or proceeding. Such service may be made by mailing by certified mail a copy of such process to the Borrower in care of the Process Agent at the Process Agent's above address, with a copy to such Person at its address specified herein and each of the Borrower hereby irrevocably authorizes and directs the Process Agent to accept such service on its behalf. As an alternative method of service, each of the Borrower also irrevocably consents to the service of any and all process in any such action or proceeding by the mailing by certified mail of copies of such process to it at its address specified herein. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. (b) Nothing in this Section 9.12 shall affect the right of any member of the Bank Group to serve legal process in any other manner permitted by law or affect the right of any member of the Bank Group to bring any action or proceeding against the Borrower, or such Person's properties, in the courts of any other jurisdiction. Section 9.13. Limitation on Interest. Each provision in this Agreement and each other Loan Document is expressly limited so that in no event whatsoever shall the amount paid, or otherwise agreed to be paid, by the Borrower for the use, forbearance or detention of the money to be loaned under this Agreement or any other Loan Document or otherwise (including any sums paid as required by any covenant or obligation contained herein or in any other Loan Document which is for the use, forbearance or detention of such money), exceed that amount of money which would cause the effective rate of interest to exceed the Highest Lawful Rate, and all amounts owed under this Agreement and each other Loan Document shall be held to be subject to reduction to the effect that such amounts so paid or agreed to be paid which are for the use, forbearance or detention of money under this Agreement or such Loan Document shall in no event exceed that amount of money which would cause the effective rate of interest to exceed the Highest Lawful Rate. To the extent that the Highest Lawful Rate applicable to a Bank is at any time determined by Texas law, such rate shall be the "indicated rate ceiling" described in Section (a)(1) of Article 1.04 of HOU04:43581.4 Chapter 1, Subtitle 1, Title 79, of the Revised Civil Statutes of Texas, 1925, as amended; provided, to the extent permitted by such Article, the Banks from time to time by notice from the Agent to Borrower may revise the aforesaid election of such interest rate ceiling as such ceiling affects the then-current or future balances of the Loans outstanding under the Notes. Notwithstanding any provision in this Agreement or any other Loan Document to the contrary, if the maturity of the Notes or the obligations in respect of the other Loan Documents are accelerated for any reason, or in the event of prepayment of all or any portion of the Notes or the obligations in respect of the other Loan Documents by the Borrower or in any other event, earned interest on the Loans and such other obligations of the Borrower may never exceed the maximum amount permitted by applicable law, and any unearned interest otherwise payable under the Notes or the obligations in respect of the other Loan Documents that is in excess of the maximum amount permitted by applicable law shall be cancelled automatically as of the date of such acceleration or prepayment or other such event and, if theretofore paid, shall be credited on the principal of the Notes or, if the principal of the Notes has been paid in full, held as collateral for any contingent or unmatured obligation of the Borrower, or, if there are no contingent or unmatured obligations of the Borrower then outstanding, refunded to the Borrower. In determining whether or not the interest paid or payable, under any specific contingency, exceeds the Highest Lawful Rate, the Borrower and the Banks shall, to the maximum extent permitted by applicable law, amortize, prorate, allocate and spread, in equal parts during the period of the actual term of this Agreement, all interest at any time contracted for, charged, received or reserved in connection with this Agreement. Section 9.14. Indemnification. The Borrower agrees to indemnify, defend and hold the Agent, the Co-Agent and each member of the Bank Group, their Affiliates and their officers, employees, agents, directors, shareholders and Affiliates (collectively, "Indemnified Persons") harmless from and against any and all loss, liability, damage, judgment, claim, deficiency or reasonable expense (including interest, penalties, reasonable attorneys' fees and amounts paid in settlement) incurred by or asserted against any Indemnified Person arising out of, in any way connected with, or as a result of (i) the execution and delivery of this Agreement and the other documents contemplated hereby, the performance by the parties hereto and thereto of its obligations hereunder and thereunder (including but not limited to the making of the Commitments of each Bank) and consummation of the transactions contemplated hereby and thereby, (ii) the actual or proposed use of the Letters of Credit or the proceeds of the Loans, (iii) any violation by the Borrower or any of its Subsidiaries of any Requirement of Law, including but not limited to Environmental Laws, (iv) ownership by the Bank Group of any real or personal property following foreclosure under the Security Documents, to the extent such losses, liabilities, damages, judgments, claims, deficiencies or expenses arise out of or result from the presence, disposal or release of any hazardous materials or solid waste in, on or under such property during the period owned, leased or operated by the Borrower or any of its Subsidiaries, including, without limitation, losses, liabilities, damages, judgments, claims, deficiencies or expenses which are imposed under Environmental Laws upon Persons by virtue of their ownership, (v) any member of the Bank Group being deemed an HOU04:43581.4 operator of any such real or personal property in circumstances in which no member of the Bank Group is generally operating or generally exercising control over such property, to the extent such losses, liabilities, damages, judgments, claims, deficiencies or expenses arise out of or result from any hazardous materials or solid waste located in, on or under such property or (vi) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnified Person is a party thereto; provided that such indemnity shall not apply to any such losses, claims, damages, liabilities or related expenses that are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnified Person. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, IT IS THE EXPRESS INTENTION OF THE BORROWER THAT EACH INDEMNIFIED PERSON SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DEFICIENCIES, JUDGMENTS OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF SUCH INDEMNIFIED PERSON. THE OBLIGATIONS OF THE BORROWER UNDER THIS SECTION 9.14 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT. Section 9.15. Ratification of Security Documents. The Borrower hereby ratifies, adopts and confirms the Liens granted by and under the Security Documents as security for all of the Obligations. The Borrower further acknowledges and agrees that the term "Secured Obligations" as defined in the Security Agreement shall include, without limitation, the payment and performance of the Obligations as defined in this Agreement. Section 9.16. Confidentiality. In the event that the Borrower provides to the Agent or the Banks written confidential information belonging to the Borrower, if the Borrower shall denominate such information in writing as "confidential", the Agent and the Banks shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without the Agent or the Banks breaching their obligation of confidence to the Borrower, (iii) are previously known by the Agent or the Banks from some source other than the Borrower, (iv) are hereafter obtained by or available to the Agent or the Banks from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (vi) are disclosed with the Borrower's consent, (vii) must be disclosed either pursuant to any Requirements of Law or to Persons regulating the activities of the Agent or the Banks, or (viii) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, the Agent or a Bank may disclose any such information to any other Bank, any independent petroleum engineers or consultants, any independent certified public HOU04:43581.4 accountants, any legal counsel employed by such Person in connection with this Agreement or any Security Document, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans; provided, however, that the Agent or Bank imposes on the Person to whom such information is disclosed the same obligation to maintain the confidentiality of such information as is imposed upon it hereunder. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three (3) years from the date the information was furnished, unless the Borrower requests in writing at least thirty (30) days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period. The Borrower waives any and all other rights it may have to confidentiality as against the Agent and the Banks arising by contract, agreement, statute or law except as expressly stated in this Section 9.16. Section 9.17. Final Agreement of the Parties. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO ORAL AGREEMENTS BETWEEN THE PARTIES.
