Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery will be included as "Proved Developed Producing Reserves" only after testing by a pilot project or after the operation of an installed program has confirmed through production response through existing completions producing to market that increased recovery will be achieved. Proved Developed Producing Reserves shall not include any Proved Developed Non-Producing Reserves. "Proved Developed Non-Producing Reserves" has the meaning assigned to that term by the Society of Petroleum Engineers, as it may be amended from time to time, but generally shall mean the subcategory of "Proved Developed Reserves" (as defined by the Society of Petroleum Engineers) which will become "Proved Developed Producing Reserves" upon minor capital expenditures being made with respect to existing wells which will cause formerly non-producing completions or intervals to become open and producing to market. "Proved Reserves" means and includes Proved Developed Producing Reserves, Proved Developed Non-Producing Reserves and Proved Undeveloped Reserves. "Proved Undeveloped Reserves" has the meaning assigned to that term by the Society of Petroleum Engineers, as it may be amended from time to time, but generally shall mean those reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. Proved Undeveloped Reserves on undrilled acreage shall be limited to those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved Undeveloped Reserves for other undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. Under no circumstances should estimates for Proved Undeveloped Reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual tests in the area and in the same reservoir.

"Unfunded Liabilities" means, with respect to any Plan at any time, the amount (if any) by which (i) the present value of all benefits under such Plan exceeds (ii) the fair market value of all Plan assets allocable to such benefits (excluding any accrued but unpaid contributions), all determined as of the then most recent valuation date for such Plan, but only to the extent that such excess represents a potential liability of the Issuer or any Subsidiary (whether direct or joint and several with one or more affiliates) to the PBGC or any other Person under Title IV of ERISA. "Wholly-Owned Subsidiary" means any Subsidiary all of the shares of capital stock or other ownership interests of which (except directors' qualifying shares) are at the time directly or indirectly owned by the Issuer. SECTION 1.02. Accounting Terms and Definitions. Unless otherwise specified herein, all accounting terms used in this Agreement shall be interpreted, all accounting determinations hereunder shall be made and all financial statements required to be delivered hereunder shall be prepared in accordance with generally accepted accounting principles as in effect from time to time, applied on a basis consistent (except for changes concurred by the Issuer's independent public accountants) with the most recent audited consolidated financial statements of the Issuer delivered to the Holders. ARTICLE II THE NOTES SECTION 2.01. Sale and Purchase of Notes. The Issuer agrees to issue and sell to each Purchaser, and subject to the terms and conditions of this Agreement, each Purchaser, severally and not jointly, agrees to purchase from the Issuer, at the Closing provided for in Section 2.02, Notes in the principal amounts specified opposite such Purchaser's name on Schedule A attached hereto. The purchase price of the Notes to be purchased by each Purchaser shall be 100% of the principal amount thereof. The Notes to be purchased by each Purchaser will be dated the date of issue thereof, will mature on the date set forth therein and will bear interest on the unpaid balance thereof from the date of issue until the principal thereof shall become due and payable, at the rate of 7.19% per annum. Interest on the Notes shall be computed on the basis of a year of 360 days, consisting of 12 30-day months, and accrued and unpaid interest on the unpaid balance thereof shall be payable semi-annually on May 15 and November 15 of each year, commencing May 15, 1998, and at maturity.

Whenever any payment of principal of, or interest on, a Note shall be due on a day which is not a Business Day, the date for payment thereof shall be extended to the next succeeding Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon will be payable for such extended time. The Notes will be in registered form substantially in the form of Exhibit A attached hereto. 11 SECTION 2.02. CLOSING. The sale and purchase of the Notes shall take place- at the offices of Milbank, Tweed, Hadley & McCloy, 1 Chase Manhattan Plaza, New York, New York 10005, at 10:00 a.m., New York City time, on November 18, 1997 or at such other time on such day as may be agreed upon by the Issuer and the Purchasers (the "Closing"). At the Closing, the Issuer will deliver to each Purchaser the Note or Notes to be purchased by such Purchaser, dated the date of the Closing and registered in such Purchaser's name (or in the name of such Purchaser's nominee), against delivery by such Purchaser to the Issuer or its order of immediately available funds in the amount of the purchase price thereof. If at the Closing the Issuer shall fail to tender such Note or Notes to such Purchaser as provided above, or any of the conditions specified in Article III shall not have been satisfied or waived, such Purchaser shall, at its election, be relieved of all further obligations under this Agreement, without thereby waiving any other rights such Purchaser may have by reason of such failure or such nonfulfillment. SECTION 2.03. Prepayments. (a) Subject to the provisions of Section 2.03(e), the Issuer shall pay $20,000,000 of the outstanding principal amount of the Notes on November 15 of each of the years 2005 through 2008, inclusive, and shall pay the remaining outstanding principal amount of the Notes together with all accrued but unpaid interest thereon, and the Notes shall finally mature, on November 15, 2009. (b) On any date (but in any event not more than four times in any fiscal year), the Issuer may prepay all or any portion of the Notes, provided that, simultaneously with any such prepayment, the Issuer shall pay accrued but unpaid interest and a prepayment charge with respect to Notes being prepaid equal to the amount (the "Make Whole Amount") not less than zero that is the excess of: (1) the sum of the Present Values of (i) the aggregate principal amount of the Notes being prepaid (assuming the principal balance of such Notes payable upon maturity and the required prepayments pursuant to Section 2.03(a) are paid when due, without regard to the prepayment in respect of which the Make Whole Amount is being calculated) and (ii) the amount of interest which would have been payable on the principal amount of such Notes (assuming the principal balance of such Notes payable upon maturity, the required prepayments pursuant to Section 2.03(a) and interest payments pursuant to the terms of such Notes are paid when due); over (2) the aggregate principal amount of the Notes being prepaid. For purposes of the definition of Make Whole Amount, "Present Value" shall be computed in accordance with generally accepted accounting principles on a semiannual basis at a discount rate equal to the sum of the Treasury Yield plus 0.50%; and the "Treasury Yield" shall be the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day prior to the date fixed for prepayment, on the display designated as Bloomberg Financial Markets "Page USD" (or such other display as may replace Bloomberg Financial Markets "Page USD") for actively traded United States Treasury securities adjusted to a constant maturity equal to the then remaining weighted average life of the Notes being prepaid (the "Remaining Life"), or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day prior to the date fixed for prepayment in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded United States Treasury securities adjusted to a constant maturity equal to the Remaining Life; provided that if the Remaining Life of the Notes is not equal to the constant maturity of a United States Treasury 12 security for which a weekly average yield is given, the Treasury Yield shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the most recent weekly average yield of United States Treasury securities for which such yields are given having a maturity as close as possible to the Remaining Life. Prepayments of Notes in accordance with this subsection (b) shall be made in minimum amounts of $5,000,000 principal amount of Notes and increments of $1,000,000. (c) The Issuer shall give each Holder at least 20 Business Days'(but not more than 60 days') notice of any anticipated prepayment of Notes pursuant to paragraph (b) of this Section 2.03, which notice shall set forth the date of the prepayment and the anticipated amount of the prepayment applicable to such Holder's Notes. Any such notice given by the Issuer hereunder shall be irrevocable. The Issuer shall, at least one Business Day prior to the date of the prepayment, give immediate notice to each Holder of the Make Whole Amount applicable to such prepayment, showing the components of the calculation thereof. (d) In the event of a Change of Control, the Issuer shall prepay the aggregate principal amount of the Notes of any Holder electing prepayment, together with accrued and unpaid interest thereon and the Make Whole Amount with respect thereto. The Issuer shall give notice (the "Change of Control Notice") to each Holder of a Change of Control within 5 Business Days of knowledge of such event. The Change of Control Notice shall include a statement of the date of occurrence of such Change of Control and a description of the facts known to the Issuer underlying such Change of Control and shall state that the Issuer is obligated, pursuant to this Section 2.03(d), to purchase Notes in respect of which a Holder shall elect prepayment. Each Holder electing prepayment shall notify the Issuer in writing of its election of prepayment (the "Election Notice") within 30-days of the date of the Change of Control Notice. The Issuer shall promptly upon receipt of an Election Notice from any Holder forward a copy of such Election Notice to all other Holders. In the event that a Change of Control occurs but no Change of Control Notice is given by the Issuer, a Holder may deliver a notice to the Issuer (a "Purchase Notice") stating that it is electing to exercise its right to require the Issuer to purchase its Notes. The Issuer shall forthwith upon receipt of any Purchase Notice give notice of the receipt of such Purchase Notice (and enclose a copy of such Purchase Notice) to all other Holders, stating that other Holders may give a similar notice to the Issuer within 30 days of the date of transmission of the copy of such Purchase Notice by the Issuer. Prepayments required to be made by this paragraph (d) shall be made on a date specified by the Issuer by at least 5 Business Days notice to the Holders electing prepayment, which date shall be no later than 15 days after the earlier of (i) the last day for submission of the Election Notice or Purchase Notice by any Holder and (ii) the date of receipt by the Issuer of an Election Notice or Purchase Notice from a Holder such that all Holders of Outstanding Notes have delivered such Notice to the Issuer. (e) The Issuer will not make any payment of any Note under this Section 2.03 unless a simultaneous payment is made to all Holders (or in the case of prepayment under subsection (d) to all Holders electing prepayment) so as to reduce ratably the obligation of the Issuer under each of the Outstanding Notes (or, in the case of prepayment under subsection (d), under each of the Outstanding Notes as to which the Holder has elected prepayment). The amount of each payment required by subsection (a) shall be reduced ratably by the aggregate principal amount of Notes prepaid in accordance with subsection (b) or (d). (f) The Issuer will not, and will not permit any of its Affiliates to, acquire directly or indirectly by purchase or prepayment or otherwise any of the Outstanding Notes except by way of payment or prepayment in accordance with the provisions of the Notes and of this 13 Agreement. Notes paid or prepaid in full in accordance with this Section 2.03 shall not be deemed Outstanding for any purpose under this Agreement. SECTION 2.04. Maximum Interest Rate. The Issuer, the Purchasers and all other Holders of the Notes specifically intend and agree to limit contractually the amount of interest, and all amounts which shall be deemed to constitute interest under applicable law, payable under this Agreement, the Notes and all other instruments and agreements related hereto and thereto to the maximum amount of interest lawfully permitted to be charged under applicable law. Therefore, none of the terms of this Agreement, the Notes or any instrument pertaining to or relating to this Agreement or the Notes shall ever be construed to create a contract to pay interest at a rate in excess of the maximum rate permitted to be charged under applicable law, and neither the Issuer nor any other party liable or to become liable hereunder, under the Notes or under any other instruments and agreements related hereto and thereto shall ever be liable for interest in excess of the amount determined at such maximum rate, and the provisions of this Section 2.04 shall control over all other provisions of this Agreement, the Notes, or any other instrument pertaining to or relating to the transactions herein contemplated. If any amount of interest taken or received by any Holder of a Note shall be in excess of said maximum amount of interest which, under applicable law, could lawfully have been collected by such Holder incident to such transactions, then such excess shall be deemed to have been the result of a mathematical error by all parties hereto and the amount of interest which would otherwise be payable hereunder or under the Notes shall be automatically reduced to the amount allowed under applicable law, and such excess shall be credited ratably against and to the extent of the unpaid principal amount of the Note or Notes held by such Holder, with the excess, if any, being refunded to the Issuer. All amounts paid or agreed to be paid in connection with such transactions which would under applicable law be deemed "interest" shall, to the extent permitted by such applicable law, be amortized, prorated, allocated and spread throughout the full stated term of this Agreement. "Maximum rate" as used in this paragraph means, with respect to each of the Notes, the maximum lawful, nonusurious rates of interest which under applicable law may be charged to the Issuer from time to time with respect to such Notes.

Corporate Existence and Power. The Issuer and each Subsidiary is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation, and has all corporate powers and all governmental licenses, authorizations, consents and approvals required to own its assets and to carry on its business as now conducted and is duly qualified as a foreign corporation in good standing in each jurisdiction where the nature of its business or the ownership or leasing of its Properties requires such qualification, except where the failure to qualify would not materially and adversely affect the conduct of its business or the enforceability of contractual obligations of the Issuer. Neither the Issuer nor any Affiliate is subject to regulation under the Public Utility Holding Company Act of 1935, the Investment Company Act of 1940, the Transportation Act (49 U.S.C.), as amended, the Federal Power Act, as amended, or any other law or regulation the application of which limits the incurrence by the Issuer of Debt hereunder, including, but not limited to, laws relating to common or contract carriers or the sale of electricity, gas, steam, water or other public utility services. SECTION 4.02. Corporate and Governmental Authorization; No Contravention. The execution, delivery and performance by the Issuer of this Agreement and the Notes are within the Issuer's corporate powers, have been duly authorized by all necessary corporate action, require no action by or in respect of, or filing with, any governmental body, agency or official and do not contravene, or constitute a default under, any provision of applicable law or regulation or of the certificate of incorporation or bylaws of the Issuer or of any agreement or instrument evidencing or governing Debt of the Issuer or any Affiliate or any other agreement, instrument, judgment, injunction, order or decree binding upon the Issuer or any Subsidiary or result in the creation or imposition of any Lien on any asset of the Issuer pursuant to any such agreement, instrument, judgment, injunction, order or decree.

SECTION 4.04. Financial Information (a) Audited Financial Statements. The consolidated balance sheets of the Issuer and its Subsidiaries as of the fiscal years ended December 31, 1994 to 1996 and the related consolidated statements of operations, cash flows and stockholders' equity for the fiscal years then ended, reported on by Coopers & Lybrand and set forth in the Offering Memorandum, a copy of which has been delivered to each of the Purchasers, fairly present, in conformity with generally accepted accounting principles, the consolidated financial position of the Issuer and its Subsidiaries as of such dates and their consolidated results of operations and cash flows for such fiscal years. (b) Reserve Data. There are no statements or conclusions in the reserve report included in the Offering Memorandum provided to Purchasers regarding reserves which are based upon or include misleading information or fail to take into account material information known to the Issuer regarding the matters reported therein, it being understood that such statements and conclusions are necessarily based upon professional opinions, estimates and forecasts, and the Issuer 16 does not warrant that such opinions, estimates and forecasts will ultimately prove to have been accurate. Such reserve data has, in the judgment of the Issuer, been properly compiled from engineering tests conducted in accordance with prevailing industry standards. (c) The financial projections and estimates and the pro forma financial statements included in the Offering Memorandum or otherwise furnished by the Issuer in connection with the Notes and this Agreement have been prepared by the Issuer in good faith on the basis of information and assumptions that the Issuer believed to be reasonable as of the date of such information, and no material assumptions have been omitted as basis for such financial projections and estimates and pro forma financial statements. (d) Since December 31, 1996, there has been no material adverse change in the business, Properties, financial position, results of operations or prospects of the Issuer or the Issuer and its Subsidiaries, considered as a whole. SECTION 4.05. Full Disclosure. None of the financial statements and other financial or factual information included in the Offering Memorandum (excluding estimates, financial projections and pro forma financial statements) contains any untrue statement of material fact or omits to state a material fact necessary in order to make the statements contained therein not misleading. All other financial and reserve information, financial statements and other documents (excluding estimates, projections and pro forma financial information) furnished by the Issuer to the Purchasers in connection with the Notes and this Agreement and set forth on Schedule 4.05 do not and will not contain any untrue statement of material fact or omit to state a material fact necessary in order to make the statements contained therein not misleading. The Issuer has disclosed to the Purchasers in writing any and all facts known to the Issuer which materially, and adversely affect the business, properties, operations or condition, financial or otherwise, of the Issuer or the Issuer and its Subsidiaries, considered as a whole or the Issuer's ability to perform its obligations under the Notes and this Agreement. SECTION 4.06. Litigation. Except as disclosed on Schedule 4.06 there is no action, suit or proceeding pending against, or to the knowledge of the Issuer threatened against or affecting, the Issuer or any of its Affiliates before any court or arbitrator or any governmental body, agency or official in which there is a reasonable possibility of an adverse decision which could individually or in the aggregate materially adversely affect the financial position of the Issuer or the Issuer and its Subsidiaries, considered as a whole or which in any manner draws into question the validity of the Notes and this Agreement. SECTION 4.07. Compliance with ERISA. (a) Each member of the ERISA Group has fulfilled its obligations under the minimum funding standards of ERISA and the Internal Revenue Code with respect to each Plan and is in compliance in all material respects with the presently applicable provisions of ERISA and the Internal Revenue Code with respect to each Plan. No member of the ERISA Group has (i) sought a waiver of the minimum funding standard under Section 412 of the Internal Revenue Code in respect of any Plan, (ii) failed to make any contribution or payment to any Plan or Multiemployer Plan, or made any amendment to any Plan, which, in either case, has resulted or could result in the imposition of a Lien on Property of the Issuer or any Subsidiary or the posting of a bond or other security by the Issuer or any Subsidiary under ERISA or the Internal Revenue Code or (iii) incurred any liability under Title IV of ERISA (other than a liability to the PBGC for premiums under Section 4007 of ERISA) which could cause the Issuer or any Subsidiary (whether directly or jointly and severally with one or more affiliates) to incur any liability. 17 (b) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406(a) of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Internal Revenue Code. The representation by the Issuer in the immediately preceding sentence is made in reliance upon and subject to the accuracy of the representation of each Purchaser in Section 7.02 as to the sources of the funds used to pay the purchase price of the Notes to be purchased by such Purchaser. SECTION 4.08. Environmental Matters. In the ordinary course of its business, the Issuer considers effects of all existing and applicable Environmental Laws on the business, operations and properties of the Issuer and its Subsidiaries, in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for cleanup or closure of properties currently or previously owned, any capital or operating expenditures required to achieve or maintain compliance with environmental protection standards imposed by law or as a condition of any license, permit or contract, any related constraints on operating activities, including any periodic or permanent shutdown of any facility or reduction in the level of or change in the nature of operations conducted thereat and any actual or potential liabilities to third parties, including employees, and any related costs and expenses). The Issuer has reasonably concluded that existing and applicable Environmental Laws are unlikely to have a material adverse effect on the business, Properties, financial condition, results of operations or prospects of the Issuer or the Issuer and its Subsidiaries, considered as a whole. The Issuer and its Subsidiaries have conducted and are conducting their respective businesses in compliance with all applicable Environmental Laws, except where the failure to so comply would not have a material adverse effect on the Issuer or the Issuer and its Subsidiaries, considered as a whole. SECTION 4.09. Taxes. The Issuer and its Subsidiaries have filed all United States Federal income tax returns and all other material tax returns which are required to be filed by them and have paid all taxes due pursuant to such returns or pursuant to any assessment received by the Issuer or any Subsidiary. The charges, accruals and reserves on the books of the Issuer and its Subsidiaries in respect of taxes or other governmental charges are adequate. SECTION 4.10. Titles, ect. The Issuer and each Subsidiary has valid and defensible title to its material (individually or in the aggregate) Petroleum Properties and good, valid, defensible and marketable title to its other real and personal property, in each case free and clear of all Liens except Liens expressly permitted by Section 5.10. Each lease under which the Issuer or any of its Subsidiaries is the lessee which is material to the business or operations of the Issuer or the Issuer and its Subsidiaries considered as a whole is valid and subsisting and is in full force and effect. SECTION 4.11. Casualities; Taking of Properties. Since the date of the reserve data included in the Offering Memorandum, neither the business nor the Petroleum Properties of the Issuer or any of its Subsidiaries have been affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property or cancellation of contract, permits or concessions by any domestic or foreign government or any agency thereof, riot, activities of armed forces or acts of God or of any public enemy, or any other event the occurrence of which, would have a material adverse effect on the business, Properties, financial condition, results of operations or prospects of the Issuer or the Issuer and its Subsidiaries, considered as a whole. SECTION 4.12. Gas Imbalances. There exists no gas imbalances, take or pay or other prepayments with respect to any Petroleum Properties which would require the Issuer or any Subsidiary to deliver hydrocarbons produced from any Petroleum Properties at some future time 18 without then or thereafter receiving full payment therefor which would be reasonably likely to have a material adverse effect on the business, Properties, financial condition, results of operations or prospects of the Issuer or the Issuer and its Subsidiaries, considered as a whole. SECTION 4.13. Use of Proceeds. The proceeds from the sale of the Notes pursuant to this Agreement will be used by the Issuer to repay indebtedness under the Credit Agreement and for general corporate purposes. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation G of the Board of Governors of the Federal Reserve System (12 CFR 207), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Issuer in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 5% of the value of the consolidated assets of the Issuer and its Subsidiaries and the Issuer does not have any present intention that margin stock will constitute more than 5% of the value of such assets. As used in this Section, the terms "margin stock" and "purpose of buying or carrying" shall have the meanings assigned to them in said Regulation G. SECTION 4.14. Offering of the Notes. Neither the Issuer nor any Person acting on behalf of the Issuer has, directly or indirectly, offered any of the Notes or any similar security of the Issuer for sale to, or solicited any offers to buy any thereof from, or otherwise approached or negotiated with respect thereto with, anyone other than the Purchasers and not more than 75 other institutional investors, each of whom were offered a portion of the Notes for purposes of investment and not for distribution. Neither the Issuer nor any Person acting on behalf of the Issuer has taken or will take any action which would cause the offer, issuance or sale of any Note to any Purchaser to violate the provisions of the Securities Act of 1933, as amended, or any other securities or blue sky laws of any applicable jurisdiction or subject the issuance or sale of the Notes to the registration requirements of Section 5 of said Securities Act. SECTION 4.15. Ownership of Subsidiaries. Schedule 4.15 sets forth a list of each Subsidiary of the Issuer and its jurisdiction of incorporation. All of the issued shares of capital stock of such Subsidiary have been duly and validly authorized and issued, are fully paid and nonassessable, and are owned directly or indirectly by the Issuer, free and clear of all Liens and restrictions on transferability or voting. ARTICLE V COVENANTS The Issuer agrees that, so long as any amount payable under any Note or this Agreement remains unpaid, it will, and will cause each of its Subsidiaries to, perform and comply with each of the following covenants, unless such performance and compliance shall have been specifically waived in writing by the Required Lenders: 19 SECTION 5.01.

SECTION 5.05. Compliance with Laws. The Issuer will comply, and will cause each Subsidiary to comply, in all material respects with all applicable laws, ordinances, rules, regulations, and requirements of governmental authorities (including, without limitation, Environmental Laws and ERISA and the rules and regulations thereunder) except for laws the violation of which could not have a material adverse effect on the Issuer or any Subsidiary and where the necessity of compliance therewith is contested in good faith by appropriate proceedings. 21 SECTION 5.06.

(iii) Immediately upon acquisition or development by the Issuer or any Subsidiary of any Petroleum Property owned directly by the Issuer or any Subsidiary and not reflected in the most recent Reserve Report, the calculation of Present Value 22 of Proved Reserves shall be increased in an amount equal to the Present Value of Proved Reserves attributable to such Petroleum Property.

As used in this Section 7.02, the terms "employee benefit plan", "governmental plan", "party in interest" and "separate account" shall have the respective meanings assigned to such terms in Section 3 of ERISA. 28 SECTION 7.03. Securities Act; Legend. Each Purchaser represents that it is an accredited investor (as defined in Regulation D of the Rules and Regulations of the Securities and Exchange Commission under the Securities Act of 1933, as amended) and that it understands the Notes have not been registered under the Securities Act of 1933. Each Purchaser acknowledges that upon issuance of the Notes, and until such time, if any, as the same is no longer required under applicable securities laws, the Notes shall bear the following legend: THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE REGISTRATION UNDER SAID ACT IS IN EFFECT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT OR IF SAID ACT DOES NOT APPLY.

Expenses; Documentary Taxes; Indemnification for Litigation.

(a) The Notes issuable under this Agreement shall be registered notes substantially in the form of Exhibit A hereto and shall be issued in denominations of $1,000,000 and any larger multiple of $50,000 (except as may otherwise be required as a result of prepayments of portions of Notes pursuant to Section 2.03). The Issuer shall keep at its principal office a register in which the Issuer shall provide for the registration of the transfers of Notes. The Issuer's principal office for such purposes shall be maintained in the continental United States and, until further notice, will be maintained at the address specified pursuant to Section 8.01. Upon surrender of any Note at such office for registration of transfer, the Issuer shall execute and deliver, at its expense, one or more new Notes of a like aggregate unpaid principal amount. Each such new Note shall be registered in the name of the designated transferee or transferees (or its nominee or nominees). At the option of the Holder of any Note such Note may be exchanged for other Notes of any authorized denominations, of a like aggregate unpaid principal amount upon surrender of the Note to be exchanged at the principal office of the Issuer. Whenever any Notes are so surrendered for exchange, the Issuer shall execute and deliver, at its expense, the Notes which the Holder thereof making the exchange is entitled to receive. Every Note presented or surrendered for registration of transfer shall be duly endorsed, or be accompanied by a written instrument of transfer duly executed by the registered Holder or his attorney duly authorized in writing. Any Note or Notes issued in exchange for any Note or upon transfer thereof shall carry the rights to unpaid interest and interest to accrue which were carried by the Note so exchanged or transferred, and neither gain nor loss of interest shall result from any such transfer or exchange. Upon the written request of any Holder, the Issuer shall promptly forward to such Holder the names and addresses of all other Holders and the principal amount of Notes held by such Holders. Upon receipt by the Issuer of evidence reasonably satisfactory to it of the ownership of and loss, theft, destruction or mutilation of any Note and (i) in case of loss, theft, or destruction, of indemnity reasonably satisfactory to it (provided that, with respect to Institutional Investors and their nominees, such Person's agreement of indemnity shall be deemed to be satisfactory) or (ii) in the case of mutilation, upon surrender and cancellation thereof, the Issuer, at its expense, will execute and deliver, in lieu thereof, a new Note of like tenor and dated and bearing interest from the date to which interest has been paid on such lost, stolen, destroyed or mutilated Note. SECTION 8.08. Persons Deemed Owners. Prior to due presentment for registration of transfer, the Issuer may treat the Person in whose name any Note is registered as the owner and holder of such Note for the purpose of receiving payment of principal of and interest and premium on such Note and for all other purposes whatsoever, whether or not such Note is or shall be overdue, and the Issuer shall not be affected by notice to the contrary. SECTION 8.09. Home Office Payment. The Issuer agrees that, so long as a Purchaser listed on the signature pages hereof or its nominee shall hold any of the Notes, it will make payments of principal of and interest and Make Whole Amounts (if any) on such Notes not later than 12:00 noon, New York City time, on the date such payment is due, in immediately available funds, at the address specified for such purpose on Schedule A or such other account or address (in the United States of America) as such Purchaser may designate in writing, notwithstanding any contrary provisions contained herein or in the Notes and without any requirement of surrendering the Notes (except that, upon the written request of the Issuer, any Note that has been paid or prepaid in full shall be surrendered for cancellation to the Issuer at its principal office maintained by the Issuer pursuant to Section 8.07). Each Purchaser agrees that, before selling or otherwise transferring any Note, it will make a notation thereon of all principal payments previously made thereon and of the date to which interest thereon has been paid. As to any subsequent Holder, the Issuer will make payments of principal of and interest on the Notes held by such Holder not later than 12:00 noon, local time, to a place within the United States on the date such payment is due, in immediately 31 available funds, by credit to the account designated by such Holder or at the option of such Holder by a check mailed or delivered to the address designated by such Holder. SECTION 8.10. Substitution. Each Purchaser may by notice to the Issuer substitute any of its wholly-owned subsidiaries as a Purchaser hereunder. Such notice shall be signed by such Purchaser and such wholly-owned subsidiary, shall contain such wholly-owned subsidiary's agreement to be bound by this Agreement and shall contain confirmation by such wholly-owned subsidiary of the accuracy with respect to it of the representations set forth in Article VII (subject to any exception necessary to reflect the intention, if any, of such wholly-owned subsidiary to transfer to such Purchaser at a subsequent date all or any of the Notes to be acquired by such wholly-owned subsidiary). The Issuer agrees that, upon receipt of such notice, all references to "Purchaser" hereunder (other than this Section 8.10) shall include a reference to such wholly-owned subsidiary and that such wholly-owned subsidiary shall have the right to transfer the Notes acquired by it hereunder to a Purchaser subsequent to such purchase. In the event that a wholly-owned subsidiary is substituted for a Purchaser in accordance with this Section 8.10 and thereafter transfers its Notes or any portion thereof to such Purchaser, the term "Purchaser" shall be deemed to refer to such wholly-owned subsidiary only if it retains any portion of the Notes, and shall refer to such Purchaser to the extent such Purchaser owns all or any portion of the Notes, and such Purchaser and such wholly-owned subsidiary (if it retains any Notes) shall each have all the rights which an original purchaser of Notes has under this Agreement. SECTION 8.11. Credit Decision. Each Purchaser acknowledges that it has, independently and without reliance upon any other Purchaser, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Purchaser also acknowledges that it will, independently and without reliance upon any other Purchaser, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under the Notes and this Agreement. SECTION 8.12. Counterparts; Integration; Effectiveness; Severability. (a) This Agreement may be signed in any number to counterparts, each of which shall be an original, and all of which taken together shall constitute a single agreement, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective when the Issuer shall have received counterparts hereof signed by all of the parties hereto (or, in the case of any Purchaser as to which an original executed counterpart shall not have been received, the Issuer shall have received from such Purchaser an executed counterpart hereof by facsimile by such Purchaser). (b) In case any provision in this Agreement or any Note shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby and such provision shall be ineffective only to the extent of such invalidity, illegality or unenforceability. SECTION 8.13. SUBMISSION TO JURISDICTION. THE ISSUER HEREBY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND OF ANY NEW YORK STATE COURT SITTING IN THE CITY OF NEW YORK FOR PURPOSES OF ALL LEGAL PROCEEDINGS WHICH MAY ARISE HEREUNDER OR UNDER THE NOTES. THE ISSUER IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW, 32 ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDINGS BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. THE ISSUER HEREBY CONSENTS TO PROCESS BEING SERVED IN ANY SUCH PROCEEDING BY THE MAILING OF A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO ITS ADDRESS SPECIFIED PURSUANT TO SECTION 8.01 OR IN ANY OTHER MANNER PERMITTED BY LAW. SECTION 8.14. Confidentiality. For the purposes of this Section 8.14, "Confidential Information" means information delivered to a Holder by or on behalf of the Issuer or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Holder as being confidential information of the Issuer or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Holder prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Holder or any person acting on its behalf, (c) otherwise becomes known to such Holder other than through disclosure by the Issuer or any Subsidiary or (d) constitutes financial statements delivered to such Holder under Section 5.01 that are otherwise publicly available. Each Holder will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Holder in good faith to protect confidential information of third parties delivered to it, provided that such Holder may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by Notes held by it), (ii) its financial advisors and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 8.14, (iii) any other holder of any Note, (iv) any Institutional Investor to which such Holder sells or offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 8.14), (v) any federal or state regulatory authority having jurisdiction over such Holder, (vi) the National Association of Insurance Commissioners or any similar organization, or any nationally recognized rating agency that requires access to information about such Holder's investment portfolio, or (vii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Holder, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Holder is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Holder may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under its Notes and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 8.14 as though it were a party to this Agreement. On reasonable request by the Issuer in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Issuer embodying the provisions of this Section 8.14. 33 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the date first above written.
