Ladies and Gentlemen:

        The undersigned, Crosstex Energy Services, L.P. (the "Company"), hereby agrees with you as follows:

        1.    AUTHORIZATION OF ISSUE OF NOTES.    The Company will authorize the issue of its senior secured promissory notes (the "Notes") in the aggregate principal amount of $50,000,000, to be dated the date of issue thereof; to mature, in the case of each Note so issued, no more than seven years after the date of original issuance thereof; to have an average life, in the case of each note so issued, of no more than five years after the date of original issuance thereof; to bear interest on the unpaid balance thereof from the date thereof at the rate per annum, and to have such other particular terms, as shall be set forth, in the case of each Note so issued, in the Confirmation of Acceptance with respect to such Note delivered pursuant to paragraph 2F; and to be substantially in the form of Exhibit A-1 attached hereto. The term "Notes" as used herein shall include each Note delivered pursuant to any provision of this Agreement and each Note delivered in substitution or exchange for any such Note pursuant to any such provision. Notes which have (i) the same final maturity, (ii) the same principal prepayment dates, (iii) the same principal prepayment amounts (as a percentage of the original principal amount of each Note), (iv) the same interest rate, (v) the same interest payment periods, and (vi) the same original date of issuance are herein called a "Series" of Notes. Capitalized terms used herein have the meanings specified in paragraph 10.

        2.    PURCHASE AND SALE OF NOTES.    

        2A.    Facility.    Prudential is willing to consider, in its sole discretion and within limits which may be authorized for purchase by Prudential Affiliates from time to time, the purchase of Notes pursuant to this Agreement. The willingness of Prudential to consider such purchase of Notes is herein called the "Facility". At any time, the aggregate principal amount of Notes stated in paragraph 1, minus the aggregate principal amount of Notes purchased and sold pursuant to this Agreement prior to such time, minus the aggregate principal amount of Accepted Notes (as hereinafter defined) which have not yet been purchased and sold hereunder prior to such time is herein called the "Available Facility Amount" at such time. NOTWITHSTANDING THE WILLINGNESS OF PRUDENTIAL TO CONSIDER PURCHASES OF NOTES BY PRUDENTIAL AFFILIATES, THIS AGREEMENT IS ENTERED INTO ON THE EXPRESS UNDERSTANDING THAT NEITHER PRUDENTIAL NOR ANY PRUDENTIAL AFFILIATE SHALL BE OBLIGATED TO MAKE OR ACCEPT OFFERS TO PURCHASE NOTES, OR TO QUOTE RATES, SPREADS OR OTHER TERMS WITH RESPECT TO SPECIFIC PURCHASES OF NOTES, AND THE FACILITY SHALL IN NO WAY BE CONSTRUED AS A COMMITMENT BY PRUDENTIAL OR ANY PRUDENTIAL AFFILIATE.

1

        2B.    Issuance Period.    Notes may be issued and sold pursuant to this Agreement until the earlier of (i) (a) if no Notes (other than the Series A Notes) have been previously issued hereunder, the second anniversary of the date of this Agreement or (b) upon receipt of the Renewal Fee provided for in paragraph 2I(4) or the issuance of Notes, prior to the second anniversary date of this Agreement, the third anniversary of the date of this Agreement (or if any such anniversary is not a Business Day, the Business Day next preceding such anniversary) and (ii) the thirtieth day after Prudential shall have given to the Company, or the Company shall have given to Prudential, written notice stating that it elects to terminate the issuance and sale of Notes pursuant to this Agreement (or if such thirtieth day is not a Business Day, the Business Day next preceding such thirtieth day). The period during which Notes may be issued and sold pursuant to this Agreement is herein called the "Issuance Period".

        2C.    Periodic Spread Information.    Provided no Default or Event of Default exists, not later than 9:30 A.M. (New York City local time) on a Business Day during the Issuance Period if there is an Available Facility Amount on such Business Day, the Company may request by telecopier or telephone, and Prudential will, to the extent reasonably practicable, provide to the Company on such Business Day (or, if such request is received after 9:30 A.M. (New York City local time) on such Business Day, on the following Business Day), information (by telecopier or telephone) with respect to various spreads at which Prudential Affiliates might be interested in purchasing Notes of different average lives; provided, however, that the Company may not make such requests more frequently than once in every five Business Days or such other period as shall be mutually agreed to by the Company and Prudential. The amount and content of information so provided shall be in the sole discretion of Prudential but it is the intent of Prudential to provide information which will be of use to the Company in determining whether to initiate procedures for use of the Facility. Information so provided shall not constitute an offer to purchase Notes, and neither Prudential nor any Prudential Affiliate shall be obligated to purchase Notes at the spreads specified. Information so provided shall be representative of potential interest only for the period commencing on the day such information is provided and ending on the earlier of the fifth Business Day after such day and the first day after such day on which further spread information is provided. Prudential may suspend or terminate providing information pursuant to this paragraph 2C for any reason, including its determination that the credit quality of the Company has declined since the date of this Agreement.

        2D.    Request for Purchase.    The Company may from time to time during the Issuance Period make requests for purchases of Notes (each such request being a "Request for Purchase"). Each Request for Purchase shall be made to Prudential by telecopier or overnight delivery service, and shall, unless otherwise expressly accepted by Prudential, (i) specify the aggregate principal amount of Notes covered thereby, which shall not be less than $10,000,000 and not be greater than the Available Facility Amount at the time such Request for Purchase is made, (ii) specify the principal amounts, final maturities, principal prepayment dates and amounts and interest payment periods (quarterly or semi-annual in arrears) of the Notes covered thereby, (iii) specify the use of proceeds of such Notes, (iv) specify the proposed day for the closing of the purchase and sale of such Notes, which shall be a Business Day during the Issuance Period not less than 10 days and not more than 25 days after the making of such Request for Purchase, (v) specify the number of the account and the name and address of the depository institution to which the purchase prices of such Notes are to be transferred on the Closing Day for such purchase and sale, (vi) certify that the representations and warranties contained in paragraph 8 are true on and as of the date of such Request for Purchase and that there exists on the date of such Request for Purchase no Event of Default or Default, (vii) specify the Designated Spread for such Notes and (viii) be substantially in the form of Exhibit B attached hereto. Each Request for Purchase shall be in writing and shall be deemed made when received by Prudential.

        2E.    Rate Quotes.    Not later than five Business Days after the Company shall have given Prudential a Request for Purchase pursuant to paragraph 2D, Prudential may, but shall be under no obligation to, provide to the Company by telephone or telecopier, in each case between 9:30 A.M. and

2

1:30 P.M. New York City local time (or such later time as Prudential may elect) interest rate quotes for the several principal amounts, maturities, principal prepayment schedules, and interest payment periods of Notes specified in such Request for Purchase. Each quote shall represent the interest rate per annum payable on the outstanding principal balance of such Notes, at which a Prudential Affiliate would be willing to purchase such Notes at 100% of the principal amount thereof.

        2F.    Acceptance.    Within 30 minutes after Prudential shall have provided any interest rate quotes pursuant to paragraph 2E or such other period as Prudential may specify to the Company (such period being the "Acceptance Window"), the Company may, subject to paragraph 2G, elect to accept such interest rate quotes as to not less than $10,000,000 aggregate principal amount of the Notes specified in the related Request for Purchase. Such election shall be made by an Authorized Officer of the Company notifying Prudential by telephone or telecopier within the Acceptance Window that the Company elects to accept such interest rate quotes, specifying the Notes (each such Note being an "Accepted Note") as to which such acceptance (an "Acceptance") relates. The day the Company notifies an Acceptance with respect to any Accepted Notes is herein called the "Acceptance Day" for such Accepted Notes. Any interest rate quotes as to which Prudential does not receive an Acceptance within the Acceptance Window shall expire, and no purchase or sale of Notes hereunder shall be made based on such expired interest rate quotes. Subject to paragraph 2G and the other terms and conditions hereof, the Company agrees to sell to a Prudential Affiliate, and Prudential agrees to cause the purchase by a Prudential Affiliate of, the Accepted Notes at 100% of the principal amount of such Notes. As soon as practicable following the Acceptance Day, the Company, Prudential and each Prudential Affiliate which is to purchase any such Accepted Notes will execute a confirmation of such Acceptance substantially in the form of Exhibit C attached hereto (a "Confirmation of Acceptance"). If the Company should fail to execute and return to Prudential within two Business Days following receipt thereof a Confirmation of Acceptance with respect to any Accepted Notes, Prudential may at its election at any time prior to its receipt thereof cancel the closing with respect to such Accepted Notes by so notifying the Company in writing.

        2G.    Market Disruption.    Notwithstanding the provisions of paragraph 2F, if Prudential shall have provided interest rate quotes pursuant to paragraph 2E and thereafter prior to the time an Acceptance with respect to such quotes shall have been notified to Prudential in accordance with paragraph 2F the domestic market for U.S. Treasury securities or derivatives shall have closed or there shall have occurred a general suspension, material limitation, or significant disruption of trading in securities generally on the New York Stock Exchange or in the domestic market for U.S. Treasury securities or derivatives, then such interest rate quotes shall expire, and no purchase or sale of Notes hereunder shall be made based on such expired interest rate quotes. If the Company thereafter notifies Prudential of the Acceptance of any such interest rate quotes, such Acceptance shall be ineffective for all purposes of this Agreement, and Prudential shall promptly notify the Company that the provisions of this paragraph 2G are applicable with respect to such Acceptance.

        2H.    Closing.    

        2H(1).    Series A Closing.    The Company hereby agrees to sell to the Purchasers and, subject to the terms and conditions herein set forth, each Purchaser agrees to purchase from the Company under the Facility 6.95% Senior Secured Notes, Series A, due 2010 (the "Series A Notes") in the aggregate principal amount set forth opposite its name on the Purchaser Schedule attached hereto at 100% of such aggregate principal amount. The Series A Notes shall be substantially in the form of Exhibit A-2 attached hereto. The Company will deliver to Prudential, at the offices of Baker Botts L.L.P. at 2001 Ross Avenue, Dallas, Texas 75201, one or more Notes registered in the name of the Purchasers, evidencing the aggregate principal amount of Series A Notes to be purchased by the Purchasers and in the denomination or denominations specified in the Purchaser Schedule attached hereto against payment of the purchase price thereof by transfer of immediately available funds to the credit of the Company's account #0880423630 at Union Bank of California, Los Angeles, California (ABA

3

No. 122000496) on the date of closing, which shall be June 3, 2003, or any other date upon which the Company and Prudential may mutually agree in writing (the "Series A Closing").

        2H(2).    Subsequent Closings.    Not later than 11:30 A.M. (New York City local time) on the Closing Day for any Accepted Notes, the Company will deliver to each Purchaser listed in the Confirmation of Acceptance relating thereto at the offices of Baker Botts L.L.P., 2001 Ross Avenue, Dallas, Texas 75201 the Accepted Notes to be purchased by such Purchaser in the form of one or more Notes in authorized denominations as such Purchaser may request for each Series of Accepted Notes to be purchased on the Closing Day, dated the Closing Day and registered in such Purchaser's name (or in the name of its nominee), against payment of the purchase price thereof by transfer of immediately available funds for credit to the Company's account specified in the Request for Purchase of such Notes.

        2H(3).    Rescheduled Closings.    If the Company fails to tender to any Purchaser the Accepted Notes to be purchased by such Purchaser on the scheduled Closing Day for such Accepted Notes as provided above in this paragraph 2H, or any of the conditions specified in paragraph 3 shall not have been fulfilled by the time required on such scheduled Closing Day, the Company shall, prior to 1:00 P.M., New York City local time, on such scheduled Closing Day notify Prudential (which notification shall be deemed received by each Purchaser) in writing whether (x) such closing is to be rescheduled (such rescheduled date to be a Business Day during the Issuance Period not less than one Business Day and not more than 30 Business Days after such scheduled Closing Day (the "Rescheduled Closing Day") and certify to Prudential (which certification shall be for the benefit of each Purchaser) that the Company reasonably believes that it will be able to comply with the conditions set forth in paragraph 3 on such Rescheduled Closing Day and that the Company will pay the Delayed Delivery Fee in accordance with paragraph 2I(3) or (y) such closing is to be canceled as provided in paragraph 2I(4). In the event that the Company shall fail to give such notice referred to in the preceding sentence, Prudential (on behalf of each Purchaser) may at its election, at any time after 1:00 P.M., New York City local time, on such scheduled Closing Day, notify the Company in writing that such closing is to be canceled as provided in paragraph 2I(4). Notwithstanding anything to the contrary appearing in this Agreement, the Company may elect to reschedule a closing with respect to any given Accepted Notes on not more than one occasion, unless Prudential shall have otherwise consented in writing.

        2I.    Fees.    

        2I(1).    Facility Fee.    In consideration for the time, effort and expense involved in the preparation, negotiation and execution of this Agreement, at the time of the execution and delivery of this Agreement by the Company and Prudential, the Company will pay to Prudential in immediately available funds a fee (the "Facility Fee") in the amount of $100,000.

        2I(2).    Issuance Fee.    The Company will pay to each Purchaser in immediately available funds a fee (the "Issuance Fee") on each Closing Day on or after June 6, 2003 in an amount equal to 0.25% of the aggregate principal amount of Notes sold to such Purchaser on such Closing Day.

        2I(3).    Delayed Delivery Fee.    If the closing of the purchase and sale of any Accepted Note is delayed for any reason (other than if the Company has satisfied all of the conditions in paragraph 3 with respect to the purchase of such Accepted Notes and the Purchasers fail to purchase such Accepted Notes) beyond the original Closing Day for such Accepted Note, the Company will pay to the Purchaser of such Accepted Note on the Cancellation Date or actual closing date of such purchase and sale a fee (the "Delayed Delivery Fee") calculated as follows:

(BEY–MMY) X DTS/360 X PA

where "BEY" means Bond Equivalent Yield, i.e., the bond equivalent yield per annum of such Accepted Note, "MMY" means Money Market Yield, i.e., the yield per annum on a commercial paper

investment of the highest quality selected by Prudential on the date Prudential receives notice of the delay in the closing for such Accepted Note having a maturity date or dates the same as, or closest to, the Rescheduled Closing Day or Rescheduled Closing Days (a new alternative investment being selected by Prudential each time such closing is delayed); "DTS" means Days to Settlement, i.e., the number of actual days elapsed from and including the original Closing Day with respect to such Accepted Note to but excluding the date of such payment; and "PA" means Principal Amount, i.e., the principal amount of the Accepted Note for which such calculation is being made. In no case shall the Delayed Delivery Fee be less than zero. Nothing contained herein shall obligate any Purchaser to purchase any Accepted Note on any day other than the Closing Day for such Accepted Note, as the same may be rescheduled from time to time in compliance with paragraph 2H.

        2I(4).    Cancellation Fee.    If the Company at any time notifies Prudential in writing that the Company is canceling the closing of the purchase and sale of any Accepted Note, or if Prudential notifies the Company in writing under the circumstances set forth in the penultimate sentence of paragraph 2H(3) that the closing of the purchase and sale of such Accepted Note is to be canceled, or if the closing of the purchase and sale of such Accepted Note is not consummated on or prior to the last day of the Issuance Period (the date of any such notification, or the last day of the Issuance Period, as the case may be, being the "Cancellation Date"), the Company will pay the Purchasers in immediately available funds an amount (the "Cancellation Fee") calculated as follows:

PI X PA

where "PI" means Price Increase, i.e., the quotient (expressed in decimals) obtained by dividing (a) the excess of the ask price (as determined by Prudential) of the Hedge Treasury Note(s) on the Cancellation Date over the bid price (as determined by Prudential) of the Hedge Treasury Notes(s) on the Acceptance Day for such Accepted Note by (b) such bid price; and "PA" has the meaning specified in paragraph 2I(3). The foregoing bid and ask prices shall be as reported by TradeWeb LLC (or, if such data for any reason ceases to be available through TradeWeb LLC, any publicly available source of similar market data). Each price shall be rounded to the second decimal place. In no case shall the Cancellation Fee be less than zero.

        2I(5).    Renewal Fee.    If no Notes (other than the Series A Notes) are issued after the date hereof until the second anniversary of the date of this Agreement, the Facility shall be terminated and the Issuance Period shall end on such anniversary date unless on or before such second anniversary the Company shall pay to Prudential a renewal fee (the "Renewal Fee") in the aggregate amount of $10,000. In the event the Company pays the Renewal Fee, the Facility shall remain in place and the Issuance Period shall extend until the third anniversary of the date of this Agreement (unless terminated earlier pursuant to paragraph 2B).

        5M.    Environmental Remediation and Indemnification.    If at any time any Hazardous Material is discovered on, under or about any Mortgaged Property or any other property owned or operated by the Company or any Subsidiary ("Other Property") and failure to remediate the same would cause the Company or any Subsidiary to be in violation of any Environmental Law, the Company will inform the Holders of the same and of the Company's proposed remediation program, and the Company or such Subsidiary will, at no cost and expense to the Collateral Agent or the Holders, and only to the extent of any legal requirement under applicable Environmental Laws for the Company or such Subsidiary to do so, remediate or remove such Hazardous Materials from such Mortgaged Property or Other Property or the groundwater underlying such Mortgaged Property or Other Property in accordance with (i) such remediation program as a prudent operator would undertake, (ii) the approval of the appropriate Governmental Persons, if any such approval is required under the applicable Environmental Laws, and (iii) all applicable Environmental Laws.

13

The Company further covenants to promptly execute and deliver at its expense (including the reasonable fees and expenses of counsel for the holders of the Notes) an amendment to this Agreement in form and substance satisfactory to the Required Holder(s) evidencing the amendment of this Agreement to include such Additional Covenants and Additional Defaults, provided that the execution and delivery of such amendment shall not be a precondition to the effectiveness of such amendment as provided for in this paragraph 5O, but shall merely be for the convenience of the parties hereto.

        7B.    Rescission of Acceleration.    At any time after any or all of the Notes shall have been declared immediately due and payable pursuant to paragraph 7A, the Required Holder(s) may, by notice in writing to the Company, rescind and annul such declaration and its consequences if (i) the Company shall have paid all overdue interest on the Notes, the principal of and Yield-Maintenance Amount, if any, payable with respect to any Notes which have become due otherwise than by reason of such declaration, and interest on such overdue interest and overdue principal and Yield Maintenance Amount at the rate specified in the Notes, (ii) the Company shall not have paid any amounts which

No remedy conferred in this Agreement upon any Holder is intended to be exclusive of any other remedy, and each and every such remedy shall be cumulative and shall be in addition to every other remedy conferred herein or now or hereafter existing at law or in equity or by statute or otherwise. All amounts recovered by any Holder as the result of the exercise of such remedies or from distributions or other payments under the Intercreditor Agreement (after application of amounts thereunder pursuant to the terms of Section 4.3 thereof) shall be applied in accordance with the following priorities (with all partial payments of amounts owing within each category being allocated ratably in accordance with the amounts so owing to each Holder): first, to the payment of all fees, indemnities, costs and expenses then owing to the Holders under the Loan Documents; second, after payment in full of the amounts set forth in clause first above, to the payment of the Yield-Maintenance Amount, if any, then owing; third, after payment in full of the amounts set forth in clause second above, to the payment of all accrued and unpaid interest then owing to the Holders under the Loan Documents; and fourth, after payment in full of the amounts set forth in clause third above, to the payment of principal then outstanding under the Notes

Such financial statements (including any related schedules and/or notes) are true and correct in all material respects (subject, as to interim statements, to changes resulting from audits and year-end adjustments), have been prepared in accordance with GAAP consistently followed throughout the periods involved and show all liabilities, direct and contingent, of the Company and its Subsidiaries required to be shown in accordance with such principles. The balance sheets fairly present the condition of the Company and its Subsidiaries as at the dates thereof, and the statements of operations, cash flows and changes in partners' capital fairly present the results of the operations of the Company and its Subsidiaries and their cash flows for the periods indicated. There has been no material adverse change in the business, property or assets, condition (financial or otherwise) operations or prospects of the Company and its Subsidiaries taken as a whole since the end of the most recent fiscal year for which such audited financial statements have been furnished.

Each of the Company and its Subsidiaries has good and defensible title to all easements and rights of way purported to be owned by it. All leases necessary in any material respect for the conduct of the respective businesses of the Company and its Subsidiaries are valid and subsisting and are in full force and effect. The Company and each Subsidiary enjoys peaceful and undisturbed possession of all easements and rights of way necessary in any material respect for the operation of its Properties. None of the Assigned Agreements, and none of the other documents

Neither the execution nor delivery of this Agreement, the Notes or any other Loan Document, nor the offering, issuance and sale of the Notes, nor fulfillment of nor compliance with the terms and provisions hereof and of the other Loan Documents will conflict with, or result in a breach of the terms, conditions or provisions of, or constitute a default under, or result in any violation of, or result in the creation of any Lien upon any of the properties or assets of the Company or any of its Subsidiaries other than the Liens created in favor of the Collateral Agent for the ratable benefit of the Holders and the Banks pursuant to, the Company Partnership Agreement or the charter or by-laws or other organizational documents of any of its Subsidiaries, any award of any arbitrator or any agreement (including any agreement with partners or members), instrument, order, judgment, decree, statute, law, rule or regulation to which the Company or any of its Subsidiaries is subject. Neither the Company nor any of its Subsidiaries is a party to, or otherwise subject to any provision contained in, any instrument evidencing Debt of the Company or such Subsidiary, any agreement relating thereto or any other contract or agreement (including its limited partnership agreement or limited liability company agreement) which limits the amount of, or otherwise imposes restrictions on the incurring of, Debt of the Company of the type to be evidenced by the Notes, or Debt of the Subsidiaries that are Guarantors of the type to be evidenced by the Guaranties, except as set forth in the agreements listed in Schedule 8G attached hereto.

Neither the Company nor any agent acting on its behalf has taken or will take any action which might cause this Agreement or the Notes to violate Regulation T, Regulation U or any other regulation of the Board of Governors of the Federal Reserve System or to violate the Exchange Act, in each case as in effect now or as the same may hereafter be in effect.

24

        8J.    ERISA.    No accumulated funding deficiency (as defined in section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect to any Plan (other than a Multiemployer Plan). No liability to the PBGC has been or is expected by the Company or any ERISA Affiliate to be incurred with respect to any Plan (other than a Multiemployer Plan) by the Company, any Subsidiary or any ERISA Affiliate which is or would be materially adverse to the business, property or assets, condition (financial or otherwise) or operations of the Company and its Subsidiaries taken as a whole. Neither the Company, any Subsidiary nor any ERISA Affiliate has incurred or presently expects to incur any withdrawal liability under Title IV of ERISA with respect to any Multiemployer Plan which is or would be materially adverse to the business, property or assets, condition (financial or otherwise) or operations of the Company and its Subsidiaries taken as a whole. The execution and delivery of this Agreement and the issuance and sale of the Notes will be exempt from or will not involve any transaction which is subject to the prohibitions of section 406 of ERISA and will not involve any transaction in connection with which a penalty could be imposed under section 502(i) of ERISA or a tax could be imposed pursuant to section 4975 of the Code. The representation by the Company in the next preceding sentence is made in reliance upon and subject to the accuracy of the representation of each Purchaser in paragraph 9B as to the source of funds to be used by it to purchase any Notes.

        8K.    Governmental Consent.    Neither the nature of the Company or of any Subsidiary, nor any of their respective businesses or properties, nor any relationship between the Company or any Subsidiary and any other Person, nor any circumstance in connection with the offering, issuance, sale or delivery of the Notes is such as to require any authorization, consent, approval, exemption or any action by or notice to or filing with any court or administrative or governmental or regulatory body (other than routine filings after the Closing Day for any Notes with the Securities and Exchange Commission and/or state Blue Sky authorities) in connection with the execution and delivery of this Agreement and the other Loan Documents, the offering, issuance, sale or delivery of the Notes or fulfillment of or compliance with the terms and provisions hereof or of the other Loan Documents.

Whenever any Notes are so surrendered for exchange, the Company shall, at its expense, execute and deliver the Notes which the Holder making the exchange is entitled to receive. Each installment of principal payable on each installment date upon each new Note issued upon any such transfer or exchange shall be in the same proportion to the unpaid principal amount of such new Note as the installment of principal payable on such date on the

42

Note surrendered for registration of transfer or exchange bore to the unpaid principal amount of such Note. No reference need be made in any such new Note to any installment or installments of principal previously due and paid upon the Note surrendered for registration of transfer or exchange. Every Note surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer duly executed, by the Holder of such Note or such Holder's 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, so that neither gain nor loss of interest shall result from any such transfer or exchange. Upon receipt of written notice from the Holder of any Note of the loss, theft, destruction or mutilation of such Note and, in the case of any such loss, theft or destruction, upon receipt of such Holder's unsecured indemnity agreement, or in the case of any such mutilation upon surrender and cancellation of such Note, the Company will make and deliver a new Note, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Note.

        11H.    Independence of Covenants.    All covenants hereunder shall be given independent effect so that if a particular action or condition is prohibited by any one of such covenants, the fact that it would be permitted by an exception to, or otherwise be in compliance within the limitations of, another covenant shall not avoid the occurrence of a Default or Event of Default if such action is taken or such condition exists.

        11I.    Notices.    All written communications provided for hereunder (other than communications provided for under paragraph 2) shall be sent by first class mail or nationwide overnight delivery service (with charges prepaid) and (i) if to any Purchaser, addressed as specified for such communications in the Purchaser Schedule attached hereto (in the case of the Series A Notes) or the Purchaser Schedule attached to the applicable Confirmation of Acceptance (in the case of any Notes issued after the date hereof) or at such other address as any such Purchaser shall have specified to the Company in writing, (ii) if to any other Holder of any Note, addressed to it at such address as it shall have specified in writing to the Company, or, if any such Holder shall not have so specified an address, then addressed to such Holder in care of the last Holder of such Note which shall have so specified an

If the date for any payment is extended to the next succeeding Business Day by reason of the preceding sentence, the period of such extension shall not be included in the computation of the interest payable on such Business Day.

        11K.    Severability.    Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Therefore, none of the terms of this Agreement, the Notes, the other Loan Documents or any instrument pertaining to or relating to this Agreement, the Notes or the other Loan Documents 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 Company, any guarantor nor any other party liable or to become liable hereunder or under the Notes, any guaranty, any other Loan Document or 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 paragraph 11S shall control over all other provisions of this Agreement, any Notes, the other Loan Documents, any guaranty or any other instrument pertaining to or relating to the transactions herein contemplated. If any amount of interest taken or received by Prudential, any Purchaser or any Holder shall be in excess of said maximum amount of interest which, under applicable law, could lawfully have been collected by Prudential, such Purchaser or 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 shall be refunded

45

promptly by the Person receiving such amount to the party paying such amount, or, at the option of the recipient, credited ratably against the unpaid principal amount of the Note or Notes held by Prudential, such Purchaser or such Holder, respectively. 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 stated term of this Agreement and the Notes. "Applicable law" as used in this paragraph means that law in effect from time to time which permits the charging and collection of the highest permissible lawful, nonusurious rate of interest on the transactions herein contemplated, and "maximum rate" as used in this paragraph means, with respect to each of the Notes, the maximum lawful, nonusurious rates of interest (if any) which under applicable law may be charged to the Company from time to time with respect to such Notes.

46

        If you are in agreement with the foregoing, please sign the form of acceptance on the enclosed counterpart of this letter and return the same to the Company, whereupon this letter shall become a binding agreement between the Company and you.
