the Letters of Credit shall (i) be issued by the Issuing Bank, (ii) contain such
terms and provisions as are reasonably required by the Issuing Bank, (iii) be
for the account of the Borrower and (iv) expire not later than the earlier to
occur of (A) one year after the date of its issuance and (B) two (2) days before
the Revolving Credit Termination Date. On and after the Closing Date, any
Letters of Credit issued and outstanding under the Prior Credit Agreement shall
be deemed to be Letters of Credit issued hereunder.

      (c) Limitation on Types of Loans. All Tranche B Loans up to the amount of
the Tranche B Aggregate Commitments shall be Fixed Rate Loans. All Tranche A
Loans up to the amount of the Tranche A Aggregate Commitments (at the option of
the Borrower, and provided that they are done in compliance with the other terms
and conditions of this Agreement) may be Base Rate Loans or LIBOR Loans;
provided that, without the prior written consent of the Tranche A Majority
Lenders, no more than six (6) LIBOR Loans may be outstanding at any time.

Section 2.02 Borrowings, Continuations and Conversions, Letters of Credit.

      (a) Borrowings. The Borrower shall give the Administrative Agent (which
shall promptly notify the applicable Lenders) advance notice as hereinafter
provided of each borrowing hereunder, which shall specify (i) the aggregate
amount of such borrowing, (ii) the Type and (iii) the date (which shall be a
Business Day) of the Loans to be borrowed, and (iv) (in the case of LIBOR Loans)
the duration of the Interest Period therefor.

      (b) Minimum Amounts. All Base Rate Loan and Fixed Rate Loan borrowings
shall be in amounts of at least $100,000 or the remaining balance of the Tranche
A Aggregate Commitments or Tranche B Aggregate Commitments (as applicable), if
less, or any whole multiple of $50,000 in excess thereof, and all LIBOR Loans
shall be in amounts of at least $500,000 or any whole multiple of $100,000 in
excess thereof.

      (c) Notices. All borrowings, continuations and conversions shall require
advance written notice to the Administrative Agent (which shall promptly notify
the applicable Lenders) in the form of Exhibit B (or telephonic notice promptly
confirmed

                                       21
<PAGE>
by such a written notice), which in each case shall be irrevocable, from the
Borrower to be received by the Administrative Agent not later than (i) 11:00
a.m. on the date of each Base Rate Loan borrowing, (ii) 12:00 noon Charlotte,
North Carolina time three Business Days prior to the date of each LIBOR Loan
borrowing, continuation or conversion, and (iii) 12:00 noon Charlotte, North
Carolina time five (5) Business Days prior to the date of each Fixed Rate Loan
borrowing. Without in any way limiting the Borrower's obligation to confirm in
writing any telephonic notice, the Administrative Agent may act without
liability upon the basis of telephonic notice believed by the Administrative
Agent in good faith to be from the Borrower prior to receipt of written
confirmation. In each such case, the Borrower hereby waives the right to dispute
the Administrative Agent's record of the terms of such telephonic notice except
in the case of gross negligence or willful misconduct by the Administrative
Agent.

      (d) Continuation Options. Subject to the provisions made in this Section
2.02(d), the Borrower may elect to continue all or any part of any LIBOR Loan
beyond the expiration of the then current Interest Period relating thereto by
giving advance notice as provided in Section 2.02(c) to the Administrative Agent
(which shall promptly notify the Tranche A Lenders) of such election, specifying
the amount of such Loan to be continued and the Interest Period therefor. In the
absence of such a timely and proper election, the Borrower shall be deemed to
have elected to convert such LIBOR Loan to a Base Rate Loan pursuant to Section
2.02(e). All or any part of any LIBOR Loan may be continued as provided herein,
provided that (i) any continuation of any such Loan shall be (as to each Loan as
continued for an applicable Interest Period) in amounts of at least $500,000 or
any whole multiple of $100,000 in excess thereof and (ii) no Default shall have
occurred and be continuing. If a Default shall have occurred and be continuing,
each LIBOR Loan shall be converted to a Base Rate Loan on the last day of the
Interest Period applicable thereto.

      (e) Conversion Options. The Borrower may elect to convert all or any part
of any LIBOR Loan on the last day of the then current Interest Period relating
thereto to a Base Rate Loan by giving advance notice to the Administrative Agent
(which shall promptly notify the Tranche A Lenders) of such election. Subject to
the provisions made in this Section 2.02(e), the Borrower may elect to convert
all or any part of any Base Rate Loan at any time and from time to time to a
LIBOR Loan by giving advance notice as provided in Section 2.02(c) to the
Administrative Agent (which shall promptly notify the Tranche A Lenders) of such
election. All or any part of any outstanding Tranche A Loan may be converted as
provided herein, provided that (i) any conversion of any Base Rate Loan into a
LIBOR Loan shall be (as to each such Loan into which there is a conversion for
an applicable Interest Period) in amounts of at least $500,000 or any whole
multiple of $100,000 in excess thereof and (ii) no Default shall have occurred
and be continuing. If a Default shall have occurred and be continuing, no Base
Rate Loan may be converted into a LIBOR Loan.

      (f) Advances. Not later than 2:00 p.m. Charlotte, North Carolina time on
the date specified for each borrowing hereunder, each applicable Lender shall
make available the amount of the Loan to be made by it on such date to the
Administrative Agent, to an account which the Administrative Agent shall
specify, in immediately available funds,

                                       22
<PAGE>
for the account of the Borrower. The amounts so received by the Administrative
Agent shall, subject to the terms and conditions of this Agreement, be made
available to the Borrower by depositing the same, in immediately available
funds, in an account of CPOC (until the hereinafter defined Required CPOC
Capital Contribution Amount has been made), designated by CPOC. All funds so
deposited with CPOC shall be recorded on the books of the Borrower as capital
contributions to CPOC until such time as the sum of such capital contributions,
together with any other capital contributions made or deemed made by the
Borrower to CPOC as a result of the forgiveness or exchange of any Debt owed by
CPOC to Borrower arising from intercompany advances made by Borrower to CPOC and
funded with the proceeds of the advances under the Prior Credit Agreement,
equals the Aggregate Maximum Credit Amount (the "Required CPOC Capital
Contribution Amount"). Thereafter, all such funds shall be made available to
Borrower by depositing the same, in immediately available funds, in an account
of the Borrower, designated by the Borrower.

(g)   Letters of Credit.

                  (i) The Borrower shall give the Issuing Bank (which shall
            promptly notify the Tranche A Lenders of such request and their
            Tranche A Percentage Share of such Letter of Credit) advance notice
            to be received by the Issuing Bank not later than 11:00 a.m.
            Charlotte, North Carolina time not less than three (3) Business Days
            prior thereto of each request for the issuance, and at least three
            (3) Business Days prior to the date of the renewal or extension, of
            a Letter of Credit hereunder which request shall specify (i) the
            amount of such Letter of Credit which shall be at least $50,000,
            (ii) the date (which shall be a Business Day) such Letter of Credit
            is to be issued, renewed or extended, (iii) the duration thereof,
            (iv) the name and address of the beneficiary thereof, (v) the type
            of the Letter of Credit and (vi) such other information as the
            Administrative Agent may reasonably request, all of which shall be
            reasonably satisfactory to the Administrative Agent. Subject to the
            terms and conditions of this Agreement, on the date specified for
            the issuance, renewal or extension of a Letter of Credit, the
            Administrative Agent shall issue, renew or extend such Letter of
            Credit to the beneficiary thereof.

                  (ii) In conjunction with the issuance of each Letter of
            Credit, the Borrower and the applicable Guarantor, if the account
            party, shall execute a Letter of Credit Agreement. In the event of
            any conflict between any provision of a Letter of Credit Agreement
            and this Agreement, the Borrower, the Issuing Bank, the
            Administrative Agent and the Tranche A Lenders hereby agree that the
            provisions of this Agreement shall govern.

                  (iii) The Issuing Bank will send to the Borrower and each
            Tranche A Lender, immediately upon issuance of any Letter of Credit,
            or an amendment thereto, a true and complete copy of such Letter of
            Credit, or such amendment thereto.

Section 2.03 Changes of Commitments.

      (a) The Aggregate Commitments shall at all times be equal to the lesser of
(i) the Aggregate Maximum Credit Amounts after adjustments resulting from
reductions pursuant to Section 2.03(b) or (ii) the Borrowing Base as determined
from time to time. The Tranche A Aggregate Commitments shall at all times be
equal to the lesser of (i) the Tranche A Aggregate Maximum Credit Amounts after
adjustments resulting from reductions pursuant to Section 2.03(b) or (ii) the
Tranche A Borrowing Base as determined from time to time. The Tranche B
Aggregate Commitments shall at all times be equal to the lesser of (i) the
Tranche B Aggregate Maximum Credit Amounts after adjustments resulting from the
reduction pursuant to Section 2.03(b) or (ii) the Tranche B Borrowing Base as
determined from time to time.

      (b) The Borrower shall have the right to terminate or to reduce the amount
of the Aggregate Maximum Credit Amounts at any time, or from time to time, upon
not less than three (3) Business Days' prior notice to the Administrative Agent
(which shall promptly notify the Lenders) of each such termination or reduction,
which notice shall specify the effective date thereof, whether such termination
or reduction is of the Tranche A Aggregate Maximum Credit Amounts or the Tranche
B Aggregate Maximum Credit Amounts, the amount of any such reduction (which
shall not be less than $1,000,000 or any whole multiple of $1,000,000 in excess
thereof), and shall be irrevocable and effective only upon receipt by the
Administrative Agent; provided, however, that (i) no termination or reduction of
the Tranche B Aggregate Maximum Credit Amounts shall be made on or before June
30, 2003, without the prior written consent of the Tranche B Majority Lenders,
and (ii) no termination or reduction of the Tranche B Aggregate Maximum Credit
Amounts shall be made at any time without the prior written consent of the
Tranche A Majority Lenders if at such time any Tranche A Loans or Letters of
Credit would remain outstanding or any Tranche A Commitments exist. Each
reduction in the Tranche A Aggregate Maximum Credit Amount shall apply pro rata
to each Tranche A Lender based on its Tranche A Percentage Share, and each
reduction in the Tranche B Aggregate Maximum Credit Amount shall apply pro rata
to each Tranche B Lender based on its Tranche B Percentage Share.

      (c) The Aggregate Maximum Credit Amounts once terminated or reduced may
not be reinstated.

Section 2.04 Fees.

      (a) Commitment Fees. The Borrower shall pay to the Administrative Agent
for the account of each Tranche A Lender a commitment fee on the daily average
unused amount of the Tranche A Aggregate Commitments for the period from and
including the Closing Date up to, but excluding, the earlier of the date the
Tranche A Aggregate Commitments are terminated or the Revolving Credit
Termination Date at a rate per annum equal to the rate set forth at the
appropriate intersection in the table set forth below:

               Greater than or equal to 50%           0.375%
</TABLE>

      Accrued commitment fees hereunder shall be payable quarterly in arrears on
      each Quarterly Date and on the earlier of the date the Tranche A Aggregate
      Commitments are terminated or the Revolving Credit Termination Date.

            (b)   Letter of Credit Fees.

                  (i) The Borrower agrees to pay the Administrative Agent, for
            the account of each Tranche A Lender, commissions for issuing the
            Letters of Credit on the daily average outstanding of the maximum
            liability of the Issuing Bank existing from time to time under such
            Letters of Credit (calculated separately for each Letter of Credit)
            at the per annum rate equal to the then effective Applicable Margin
            for LIBOR Loans, provided that each Letter of Credit shall bear a
            minimum commission of $500. Each Letter of Credit shall be deemed to
            be outstanding up to the full face amount of the Letter of Credit
            until the Issuing Bank has received the canceled Letter of Credit or
            a written cancellation of the Letter of Credit from the beneficiary
            of such Letter of Credit in form and substance acceptable to the
            Issuing Bank, or for any reductions in the amount of the Letter of
            Credit (other than from a drawing), written notification from the
            beneficiary of such Letter of Credit. Such commissions are payable
            quarterly in arrears on each Quarterly Date and upon cancellation or
            expiration of each such Letter of Credit.

                  (ii) The Issuing Bank, for its own account, shall receive
            0.125% of the face amount of each Letter of Credit as an issuing
            fee.

            (c) Fee Letters. The Borrower shall pay to the Administrative Agent
      and the Tranche B Lenders such other fees as are set forth in the Fee
      Letters on the Closing Date (or any other specified date) and in the
      amounts specified therein. Payment of such fees that are due on the
      Closing Date to any Lender is a condition precedent to such Lender's
      obligation to make its part of the Initial Funding.

      Section 2.05 Several Obligations. The failure of any Lender to make any
Loan to be made by it or to provide funds for disbursements or reimbursements
under Letters of Credit on the date specified therefor shall not relieve any
other Lender of its obligation to make its Loan or provide funds on such date,
but no Lender shall be responsible for the failure of any other Lender to make a
Loan to be made by such other Lender or to provide funds to be provided by such
other Lender.

      Section 2.06 Notes. The Loans made by each Lender shall be evidenced by a
single promissory note of the Borrower in substantially the form of Exhibit A-1
or A-2, as appropriate, dated (i) the Closing Date or (ii) the effective date of
an Assignment pursuant to Section

                                       25
<PAGE>
12.06(b), payable to the order of such Lender in a principal amount equal to its
Maximum Credit Amount as originally in effect and otherwise duly completed and
such substitute Notes as required by Section 12.06(b). The date, amount, Type,
interest rate and Interest Period of each Loan made by each Lender, and all
payments made on account of the principal thereof, shall be recorded by such
Lender on its books for its Note, and, prior to any transfer may be endorsed by
such Lender on the schedule attached to such Note or any continuation thereof or
on any separate record maintained by such Lender. Failure to make any such
notation or to attach a schedule shall not affect any Lender's or the Borrower's
rights or obligations in respect of such Loans or affect the validity of such
transfer by any Lender of its Note.

      Section 2.07 Prepayments.

            (a) Voluntary Prepayments. The Borrower may prepay the Base Rate
      Loans upon not less than one (1) Business Day's prior notice to the
      Administrative Agent (which shall promptly notify the Lenders), which
      notice shall specify the prepayment date (which shall be a Business Day)
      and the amount of the prepayment (which shall be at least $100,000 or the
      remaining aggregate principal balance outstanding on the Notes) and shall
      be irrevocable and effective only upon receipt by the Administrative
      Agent. The Borrower may prepay LIBOR Loans (except that prior notice to
      the Administrative Agent shall be not less than three (3) Business Days
      for LIBOR Loans) and in addition such prepayments of LIBOR Loans shall be
      subject to the terms of Section 5.05 and shall be in an amount equal to
      all of the LIBOR Loans for the Interest Period prepaid provided that
      interest on the principal prepaid, accrued to the prepayment date, shall
      be paid on the prepayment date.

            The Borrower may prepay Tranche B Loans upon not less than thirty
      (30) days notice to the Administrative Agent (which shall promptly notify
      the Tranche B Lenders); provided, however, that no such prepayment may be
      made on or before June 30, 2003, without the prior written consent of the
      Tranche B Majority Lenders. At or prior to the time of such prepayment,
      the Tranche A Lenders will, in their sole and absolute discretion, have
      the right to make an immediate redetermination of the Borrowing Base, and
      no such prepayment shall be made if, after giving effect thereto and to
      such redetermined Borrowing Base, a Borrowing Base Deficiency would exist.
      Any prepayment of Tranche B Loans hereunder shall automatically and
      without further notice or other action result in (i) a reduction of the
      Tranche B Aggregate Maximum Credit Amount by the amount of such prepayment
      (pro rata to each Tranche B Lender based on its Tranche B Percentage
      Share), and (ii) unless the Tranche A Aggregate Maximum Credit Amount has
      been sooner terminated pursuant to Section 2.03(b), an increase of the
      Tranche A Aggregate Maximum Credit Amount by an amount equal to such
      prepayment (pro rata to each Tranche A Lender based on its Tranche A
      Percentage Share).

            (b)   Mandatory Prepayments.

                  (i) If, after giving effect to any optional termination or
            reduction by the Borrower of the Tranche A Aggregate Maximum Credit
            Amounts pursuant to Section 2.03(b), the outstanding aggregate
            principal amount of the Tranche A Loans plus the LC Exposure exceeds
            the Tranche A Aggregate Maximum Credit

                                       26
<PAGE>
            Amounts, the Borrower shall (i) prepay the Tranche A Loans on the
            date of such termination or reduction in an aggregate principal
            amount equal to the excess, together with interest on the principal
            amount paid accrued to the date of such prepayment and (ii) if any
            excess remains after prepaying all of the Tranche A Loans because of
            LC Exposure, pay to the Administrative Agent on behalf of the
            Lenders an amount equal to the excess to be held as cash collateral
            as provided in Section 2.10(b) hereof. If, after giving effect to
            any optional termination or reduction by the Borrower of the Tranche
            B Aggregate Maximum Credit Amounts pursuant to Section 2.03(b), the
            outstanding aggregate principal amount of the Tranche B Loans
            exceeds the Tranche B Aggregate Maximum Credit Amounts, the Borrower
            shall prepay the Tranche B Loans on the date of such termination or
            reduction in an aggregate principal amount equal to the excess,
            together with interest on the principal amount paid accrued to the
            date of such prepayment and a prepayment premium calculated pursuant
            to Section 2.07(d); provided, however, that no prepayment may be
            made at any time without the prior written consent of the Tranche A
            Majority Lenders, as provided for in Section 2.03(b), if any Tranche
            A Loans or Letters of Credit remain outstanding or any Tranche A
            Commitments exist at the time of such proposed prepayment of Tranche
            B Loans.

                  (ii) Upon any redetermination of the amount of the Borrowing
            Base in accordance with Section 2.08, if the redetermined Borrowing
            Base results in a Borrowing Base Deficiency, then the Borrower shall
            within thirty (30) days of receipt of written notice thereof either:
            (A) prepay the Loans (and provide cash collateral for the Letter of
            Credit) in an aggregate principal amount equal to the Borrowing Base
            Deficiency, together with interest on the principal amount paid
            accrued to the date of such prepayment; or (B) the Borrower shall
            notify the Administrative Agent (which will promptly notify the
            Lenders) in writing of the Borrower's election to initiate a
            Deficiency Period during which it will eliminate such Borrowing Base
            Deficiency by making six (6) consecutive monthly Deficiency
            Payments, the first of such payments being due and payable with the
            delivery to the Administrative Agent of such notice and each of the
            remaining payments due and payable on the same day of each month
            thereafter during the Deficiency Period; provided however, in the
            event of an acceleration of the maturity of the Notes pursuant to
            Section 10.02 hereof, such acceleration shall also accelerate the
            maturity of all outstanding and unpaid Deficiency Payments. All
            payments under this subsection (ii), whether a single payment under
            clause (A) or monthly Deficiency Payments under clause (B), shall be
            applied in the order of priority specified in Section 3.03, and any
            payments required by Section 3.03(a)(iii) to be held as cash
            collateral shall be held in accordance with Section 2.10(b).

            (c) Generally. Prepayments permitted or required under this Section
      2.07 shall be without premium or penalty, except as required under Section
      5.05 for prepayment of LIBOR Loans and under Section 2.07(d) for
      prepayment of Fixed Rate Loans. Any prepayments on the Tranche A Loans may
      be reborrowed subject to the then effective Aggregate Commitments.

            (d) Prepayment Premium for Tranche B Loans. If the Borrower elects
      to reduce the Tranche B Aggregate Maximum Credit Amounts, resulting in a
      prepayment on the Tranche B Loans pursuant to Section 2.07(b)(i), or if
      the Borrower elects to make a voluntary prepayment of the Tranche B Loans
      pursuant to Section 2.07(a), the Borrower will, at the same time that it
      makes such prepayment, pay the Tranche B Lenders (i) all interest then
      accrued on the principal prepaid on the Tranche B Loans, plus (ii) a
      prepayment premium in an aggregate amount equal to the amount of principal
      so prepaid multiplied by the applicable percentage as follows:

      Section 2.08 Borrowing Base.

            (a) The Borrowing Base shall be determined in accordance with
      Section 2.08(b) by the Administrative Agent with the concurrence of the
      Tranche A Majority Lenders and is subject to redetermination in accordance
      with Section 2.08(d). Upon any redetermination of the Borrowing Base, such
      redetermination shall remain in effect until the next successive
      Redetermination Date. So long as any of the Commitments are in effect or
      any LC Exposure or Loans are outstanding hereunder, this facility shall be
      governed by the then effective Borrowing Base. During the period from and
      after the Closing Date until September 30, 2002, and thereafter until the
      first redetermination pursuant to Section 2.08(d) or the first adjustment
      pursuant to Section 8.08(c), the amount of the Borrowing Base shall be
      $75,000,000. The Tranche B Borrowing Base shall be $30,000,000 on the
      Closing Date and shall thereafter be the least of (i) the Borrowing Base,
      (ii) the Tranche B Aggregate Maximum Credit Amounts, and (iii) the unpaid
      principal balance of the Tranche B Loans, all as determined at the time in
      question. The Tranche A Borrowing Base shall be the difference of the
      Borrowing Base minus the Tranche B Borrowing Base. The Availability under
      the Borrowing Base shall be limited by any principal amounts which have to
      be paid on the 2002 Subordinated Notes in September 2002 in accordance
      with Section 6.02(d).

            (b) Upon receipt of the reports required by Section 8.07 and such
      other reports, data and supplemental information as may from time to time
      be reasonably requested by the Administrative Agent (the "Engineering
      Reports"), the Administrative Agent will redetermine the Borrowing Base.
      Except for redeterminations of the Borrowing Base as provided in Sections
      2.07(a) and 9.16, which shall be redetermined in any amount at the sole
      and absolute discretion (and without having to follow normal and customary
      procedures of the Administrative Agent, any of the Lenders, or of the
      lending industry) of the Administrative Agent, such redetermination will
      be in accordance with its normal and customary procedures for evaluating
      oil and gas reserves and other related assets as such exist at that
      particular time, and the Administrative Agent, in its sole discretion, may
      make adjustments to the rates, volumes and prices and other assumptions

                                       28
<PAGE>
      set forth therein in accordance with its normal and customary procedures
      for evaluating oil and gas reserves and other related assets as such exist
      at that particular time. The Administrative Agent shall propose to the
      Tranche A Lenders a new Borrowing Base within 14 days following receipt by
      the Administrative Agent and the Tranche A Lenders of the Engineering
      Reports in a timely and complete manner. After having received notice of
      such proposal by the Administrative Agent, the Tranche A Lenders shall
      have 14 days to agree or disagree with such proposal. Any Tranche A
      Lenders that have not communicated their approval or disapproval at the
      end of the 14 days shall be deemed to have approved the Administrative
      Agent's proposal of the redetermined Borrowing Base. To the extent that
      within such 14 days the Administrative Agent has not received the
      requisite number of approvals from the Tranche A Lenders of the
      redetermined Borrowing Base, the requisite number of Tranche A Lenders
      shall, within a reasonable period of time, agree on a new Borrowing Base.
      Any increase in the Borrowing Base must be approved by the Administrative
      Agent and all of the Tranche A Lenders and any decrease in or
      reaffirmation of the existing Borrowing Base must be approved by the
      Tranche A Majority Lenders and, if the decrease of the existing Borrowing
      Base reduces the Borrowing Base below the Tranche B Aggregate Maximum
      Credit Amount, then such decrease must also be approved by the Tranche B
      Majority Lenders.

            (c) The Administrative Agent may exclude any Oil and Gas Property or
      portion of production therefrom or any income from any other Property from
      the Borrowing Base, at any time, because title information is not
      reasonably satisfactory, such Property is not Collateral or such Property
      is not assignable.

            (d) So long as any of the Commitments are in effect and until
      payment in full of all Loans hereunder, on or around the first Business
      Day of each April and October, commencing October 1, 2002, (each being a
      "Scheduled Redetermination Date"), the Tranche A Lenders shall redetermine
      the amount of the Borrowing Base in accordance with Section 2.08(b). In
      addition, (i) the Borrower may initiate a redetermination of the Borrowing
      Base at any other time as it so elects by specifying in writing to the
      Administrative Agent (who will promptly notify the Lenders) the date by
      which the Borrower will furnish to the Administrative Agent and all of the
      Lenders a Reserve Report in accordance with Section 8.07(b) and the date
      by which such redetermination is requested to occur; provided, however,
      that the Borrower may initiate only one such unscheduled redetermination
      between Scheduled Redetermination Dates during the first twelve (12)
      months after the Closing Date and thereafter, may initiate only one such
      unscheduled redetermination per year and (ii) the Tranche A Majority
      Lenders may initiate a redetermination of the Borrowing Base at any other
      time as they so elect by specifying in writing to the Borrower the date by
      which the Borrower is to furnish a Reserve Report in accordance with
      Section 8.07(b) and the date on which such redetermination is to occur;
      provided, however, that the Tranche A Majority Lenders may initiate only
      one such unscheduled redetermination between Scheduled Redetermination
      Dates during the first twelve (12) months after the Closing Date and
      thereafter, may initiate only one such unscheduled redetermination per
      year except as provided hereinbelow in this Section 2.08(d). No such
      unscheduled redetermination shall cause a reduction in the Borrowing Base
      on or before September 30, 2002. In addition, the

                                       29
<PAGE>
      Tranche A Majority Lenders, in their sole discretion, may redetermine the
      Borrowing Base as provided in Section 2.07(a) and Section 9.16.

            (e) The Administrative Agent shall promptly notify in writing the
      Borrower and the Lenders of the new Borrowing Base. Any redetermination of
      the Borrowing Base shall not be in effect until written notice is received
      by the Borrower.

            (f) The Tranche B Lenders shall be entitled to exercise all rights
      of the Tranche A Lenders under this Section 2.08 (and to redetermine the
      Borrowing Base pursuant to Section 9.16) whenever no Tranche A Loans or
      Letters of Credit remain outstanding and no Tranche A Commitments exist.

      Section 2.09 Assumption of Risks. The Borrower assumes all risks of the
acts or omissions of any beneficiary of any Letter of Credit or any transferee
thereof with respect to its use of such Letter of Credit. Neither the Issuing
Bank (except in the case of gross negligence or willful misconduct on the part
of the Issuing Bank or any of its employees), its correspondents nor any Lender
shall be responsible for the validity, sufficiency or genuineness of
certificates or other documents or any endorsements thereon, even if such
certificates or other documents should in fact prove to be invalid,
insufficient, fraudulent or forged; for errors, omissions, interruptions or
delays in transmissions or delivery of any messages by mail, telex, or
otherwise, whether or not they be in code; for errors in translation or for
errors in interpretation of technical terms; the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign any
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason;
the failure of any beneficiary or any transferee of any Letter of Credit to
comply fully with conditions required in order to draw upon any Letter of
Credit; or for any other consequences arising from causes beyond the Issuing
Bank's control or the control of the Issuing Bank's correspondents. In addition,
neither the Issuing Bank, the Administrative Agent nor any Lender shall be
responsible for any error, neglect, or default of any of the Issuing Bank's
correspondents; and none of the above shall affect, impair or prevent the
vesting of any of the Issuing Bank's, the Administrative Agent's or any Lender's
rights or powers hereunder or under the Letter of Credit Agreements, all of
which rights shall be cumulative. The Issuing Bank and its correspondents may
accept certificates or other documents that appear on their face to be in order,
without responsibility for further investigation of any matter contained therein
regardless of any notice or information to the contrary. In furtherance and not
in limitation of the foregoing provisions, the Borrower agrees that any action,
inaction or omission taken or not taken by the Issuing Bank or by any
correspondent for the Issuing Bank in good faith in connection with any Letter
of Credit, or any related drafts, certificates, documents or instruments, shall
be binding on the Borrower and shall not put the Issuing Bank or its
correspondents under any resulting liability to the Borrower.

      Section 2.10 Obligation to Reimburse and to Prepay.

            (a) If a disbursement by the Issuing Bank is made under any Letter
      of Credit, the Borrower shall pay to the Administrative Agent within two
      (2) Business Days after notice of any such disbursement is received by the
      Borrower, the amount of each such disbursement made by the Issuing Bank
      under the Letter of Credit (if such payment is not sooner effected as may
      be required under this Section 2.10 or under other provisions of

                                       30
<PAGE>
      the Letter of Credit), together with interest on the amount disbursed from
      and including the date of disbursement until payment in full of such
      disbursed amount at a varying rate per annum equal to (i) the then
      applicable interest rate for Base Rate Loans through the second Business
      Day after notice of such disbursement is received by the Borrower and (ii)
      thereafter, the Post-Default Rate for Base Rate Loans (but in no event to
      exceed the Highest Lawful Rate) for the period from and including the
      third Business Day following the date of such disbursement to and
      including the date of repayment in full of such disbursed amount. The
      obligations of the Borrower under this Agreement with respect to each
      Letter of Credit shall be absolute, unconditional and irrevocable and
      shall be paid or performed strictly in accordance with the terms of this
      Agreement under all circumstances whatsoever, including, without
      limitation, but only to the fullest extent permitted by applicable law,
      the following circumstances: (i) any lack of validity or enforceability of
      this Agreement, any Letter of Credit or any of the Security Instruments;
      (ii) any amendment or waiver of (including any default), or any consent to
      departure from this Agreement (except to the extent permitted by any
      amendment or waiver), any Letter of Credit or any of the Security
      Instruments; (iii) the existence of any claim, set-off, defense or other
      rights which the Borrower may have at any time against the beneficiary of
      any Letter of Credit or any transferee of any Letter of Credit (or any
      Persons for whom any such beneficiary or any such transferee may be
      acting), the Issuing Bank, the Administrative Agent, any Lender or any
      other Person, whether in connection with this Agreement, any Letter of
      Credit, the Security Instruments, the transactions contemplated hereby or
      any unrelated transaction; (iv) any statement, certificate, draft, notice
      or any other document presented under any Letter of Credit proves to have
      been forged, fraudulent, insufficient or invalid in any respect or any
      statement therein proves to have been untrue or inaccurate in any respect
      whatsoever; (v) payment by the Issuing Bank under any Letter of Credit
      against presentation of a draft or certificate which appears on its face
      to comply, but does not comply, with the terms of such Letter of Credit;
      and (vi) any other circumstance or happening whatsoever, whether or not
      similar to any of the foregoing.

      Notwithstanding anything in this Agreement to the contrary, the Borrower
      will not be liable for payment or performance that results from the gross
      negligence or willful misconduct of the Issuing Bank, except where the
      Borrower or any Subsidiary actually recovers the proceeds for itself or
      the Issuing Bank of any payment made by the Issuing Bank in connection
      with such gross negligence or willful misconduct.

            (b) In the event of a payment or prepayment pursuant to Section
      2.07(b) or the maturity of the Notes, whether by acceleration or
      otherwise, an amount equal to the LC Exposure (or the excess in the case
      of Section 2.07(b)) shall be deemed to be forthwith due and owing by the
      Borrower to the Issuing Bank, the Administrative Agent and the Tranche A
      Lenders as of the date of any such occurrence; and the Borrower's
      obligation to pay such amount shall be absolute and unconditional, without
      regard to whether any beneficiary of any such Letter of Credit has
      attempted to draw down all or a portion of such amount under the terms of
      a Letter of Credit, and, to the fullest extent permitted by applicable
      law, shall not be subject to any defense or be affected by a right of
      set-off, counterclaim or recoupment which the Borrower may now or
      hereafter have against any such beneficiary, the Issuing Bank, the
      Administrative Agent, the Lenders or any other

                                       31
<PAGE>
      Person for any reason whatsoever. Such payments shall be held by the
      Issuing Bank on behalf of the Tranche A Lenders as cash collateral
      securing the LC Exposure in an account or accounts at the Principal
      Office; and the Borrower hereby grants to and by its deposit with the
      Administrative Agent grants to the Administrative Agent a security
      interest in such cash collateral. In the event of any such payment by the
      Borrower of amounts contingently owing under outstanding Letters of Credit
      and in the event that thereafter drafts or other demands for payment
      complying with the terms of such Letters of Credit are not made prior to
      the respective expiration dates thereof, the Administrative Agent agrees,
      if no Event of Default has occurred and is continuing or if no other
      amounts are outstanding under this Agreement, the Notes or the Security
      Instruments, to remit to the Borrower amounts for which the contingent
      obligations evidenced by the Letters of Credit have ceased.

            (c) Each Tranche A Lender severally and unconditionally agrees that
      it shall promptly reimburse the Issuing Bank an amount equal to such
      Tranche A Lender's Tranche A Percentage Share of any disbursement made by
      the Issuing Bank under any Letter of Credit that is not reimbursed
      according to this Section 2.10.

            (d) Notwithstanding anything to the contrary contained herein, if no
      Default exists and subject to availability under the Tranche A Aggregate
      Maximum Credit Amount (after reduction for LC Exposure), to the extent the
      Borrower has not reimbursed the Issuing Bank for any drawn upon Letter of
      Credit within one (1) Business Day after notice of such disbursement has
      been received by the Borrower, the amount of such Letter of Credit
      reimbursement obligation shall automatically be funded by the Tranche A
      Lenders as a Base Rate Loan hereunder and used by the Tranche A Lenders to
      pay such Letter of Credit reimbursement obligation. If an Event of Default
      has occurred and is continuing, or if the funding of such Letter of Credit
      reimbursement obligation as a Base Rate Loan would cause the aggregate
      amount of all Tranche A Loans outstanding to exceed the Tranche A
      Aggregate Maximum Credit Amount (after reduction for LC Exposure), such
      Letter of Credit reimbursement obligation shall not be funded as a Base
      Rate Loan, but instead shall accrue interest as provided in Section
      2.10(a).

      Section 2.11 Lending Offices. The Loans of each Type made by each Lender
shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type.

                                  ARTICLE III

                       PAYMENTS OF PRINCIPAL AND INTEREST

      Section 3.01 Repayment of Principal.

            (a) Loans. On the Revolving Credit Termination Date the Borrower
      shall repay the outstanding aggregate principal of the Loans and the Notes
      evidencing the Loans.

            (b) Generally. The Borrower will pay to the Administrative Agent,
      for the account of each Lender, the principal payments required by this
      Section 3.01.

                                       32
<PAGE>
            Section 3.02 Payment of Interest.

            (a) Interest Rates. The Borrower will pay to the Administrative
      Agent, for the account of each Lender, interest on the unpaid principal
      amount of each Loan made by such Lender for the period commencing on the
      date such Loan is made to, but excluding, the date such Loan shall be paid
      in full, at the following rates per annum:

                  (i) if such a Loan is a Base Rate Loan, the Base Rate (as in
            effect from time to time) plus the Applicable Margin, but in no
            event to exceed the Highest Lawful Rate;

                  (ii) if such a Loan is a LIBOR Loan, for each Interest Period
            relating thereto, the LIBOR Rate for such Loan plus the Applicable
            Margin (as in effect from time to time), but in no event to exceed
            the Highest Lawful Rate; and

                  (iii) if such a Loan is a Fixed Rate Loan, the Fixed Rate, but
            in no event to exceed the Highest Lawful Rate.

            (b) Post-Default Rate. Notwithstanding the foregoing, the Borrower
      will pay to the Administrative Agent, for the account of each Lender
      interest at the applicable Post-Default Rate on any principal of any Loan
      made by such Lender, and (to the fullest extent permitted by law) on any
      other amount payable by the Borrower hereunder, under any Loan Document or
      under any Note held by such Lender to or for account of such Lender, for
      the period commencing on the date of an Event of Default until the same is
      paid in full or all Events of Default are cured or waived.

            (c) Due Dates. Accrued interest on Base Rate Loans and the Fixed
      Rate Loans shall be payable on each Quarterly Date commencing on September
      27, 2002; provided, however, that if accrued interest on each LIBOR Loan
      shall be payable on the last day of the Interest Period therefor and, if
      such Interest Period is longer than three months at three-month intervals
      following the first day of such Interest Period, except that interest
      payable at the Post-Default Rate shall be payable from time to time on
      demand and interest on any LIBOR Loan that is converted into a Base Rate
      Loan (pursuant to Section 5.04) shall be payable on the date of conversion
      (but only to the extent so converted). Any accrued and unpaid interest on
      the Loans on the Revolving Credit Termination Date shall be paid on such
      date.

            (d) Determination of Rates. Promptly after the determination of any
      interest rate provided for herein or any change therein, the
      Administrative Agent shall notify the Lenders to which such interest is
      payable and the Borrower thereof. Each determination by the Administrative
      Agent of an interest rate or fee hereunder shall, except in cases of
      manifest error, be final, conclusive and binding on the parties.

      Section 3.03 Payment Waterfall. Notwithstanding any other provision in
this Agreement or any other Loan Document to the contrary:

            (a) Whenever the Borrower (or any Guarantor) pays or is required to
      make payments on the Obligations, or whenever any Lender receives (and
      such funds were not

                                       33
<PAGE>
      received from the Administrative Agent in accordance with the priorities
      established by this Section 3.03) or has the right to receive funds to be
      applied to the Obligations (whether in bankruptcy, pursuant to Section
      4.05, or otherwise), or whenever the Administrative Agent holds proceeds
      of collection or other funds to be applied to the Obligations, in each
      case whether before or after maturity (and notwithstanding any bankruptcy,
      insolvency, or any other proceeding), such payments shall be made and such
      proceeds and other funds shall be applied in the following order of
      priority:

                  (i) first, to reimbursements of expenses and payment of
            indemnities due and owing at the time in question to the
            Administrative Agent or the Tranche A Lenders under this Agreement
            and the other Loan Documents;

                  (ii) second, to accrued interest (including, without
            limitation, interest which may accrue subsequent to Borrower or any
            Guarantor becoming subject to any state or federal debtor-relief
            statute), fees, and principal then due and owing to the Tranche A
            Lenders (whether such principal is due and owing at maturity, due to
            acceleration, or due to a reduction in the Borrowing Base, or for
            any reason), together with any payments then due and owing to the
            Tranche A Lenders under Hedging Agreements permitted hereunder;

                  (iii) third, to the extent expressly required at such time
            under Section 2.10(b), to serve as cash collateral to be held by the
            Administrative Agent to secure the LC Exposure;

                  (iv) fourth, to reimbursements of expenses and payment of
            indemnities then due and owing to the Tranche B Lenders under this
            Agreement and the other Loan Documents;

                  (v) fifth, to accrued interest (including, without limitation,
            interest which may accrue subsequent to Borrower or any Guarantor
            becoming subject to any state or federal debtor-relief statute) and
            fees then due and owing to the Tranche B Lenders, together with any
            prepayments of principal on the Tranche B Loans that have been
            approved by the Tranche A Majority Lenders (whether under Section
            2.07 or otherwise);

                  (vi) sixth, to the prepayment of principal on the Tranche A
            Loans until they are paid in full;

                  (vii) seventh, to the payment or prepayment of principal on
            the Tranche B Loans until they are paid in full;

                  (viii) eighth, to the pro rata payment of all other
            Obligations; and

                  (ix) last, any excess shall be paid to the Borrower or as
            otherwise required by any Governmental Requirement.

            (b) Payments must be made in accordance with the foregoing order of
      priority whether or not the Borrower provides sufficient funds to make all
      payments due on the

                                       34
<PAGE>
      Obligations at the time in question, but compliance with such order of
      priority does not relieve the Borrower of its duty to make all payments of
      the Obligations whenever they become due and any breach of such duty shall
      constitute an Event of Default or Default as provided in Section 10.01.

            (c) Should any Lender receive any funds to be applied to the
      Obligations from any source whatsoever (whether in bankruptcy, pursuant to
      Section 4.05, or otherwise) and such funds have not been distributed to
      the Lenders in accordance with the provisions of this Section 3.03, such
      funds shall immediately be paid to the Administrative Agent who shall
      distribute such funds in accordance with the provisions of this Section
      3.03. Without in any manner limiting the generality of the foregoing, if
      any petition is filed or any proceeding is instituted by or against
      Borrower or any Guarantor under any provisions of the Bankruptcy Reform
      Act, Title 11 of the United States Code, or any other or similar law
      relating to bankruptcy, insolvency, reorganization or other relief for
      debtors, or generally affecting creditors' rights, or seeking the
      appointment of a receiver, trustee, custodian or liquidator of or for
      Borrower or any Guarantor or any of their assets, any payment or
      distribution of any of Borrower's or any Guarantor's assets, whether in
      cash, securities or any other property, which would be payable or
      deliverable with respect to any of the Obligations owed to the Tranche B
      Lenders, shall be paid or delivered to the Administrative Agent to be paid
      in accordance with the procedures and priority established in this Section
      3.03. The Lenders grant to the Administrative Agent the right to enforce,
      collect and receive any such payment or distribution and to give releases
      or acquittances therefor, subject, however to the express provisions
      contained in this Agreement permitting all or certain Lenders to direct
      the Administrative Agent to act or refrain from acting; provided, however,
      that nothing contained in this section shall prohibit the Lenders from
      suing for collections of principal on the Notes at maturity or for
      collection of interest on the Notes provided that the Administrative Agent
      has not already commenced such suits, and provided that the Lenders have
      the right to bring such suits under the provisions of this Agreement
      including, without limitation, all provisions under Section 10.02
      (provided that, with respect to any exercise of remedies by the Tranche B
      Lenders under Section 10.02(c), the 180 day period in Section 10.02(c)
      must have elapsed); and provided further that if any sums are collected by
      any of the Lenders, they will be paid to the Administrative Agent for
      payment and distribution in accordance with Section 3.03. Each Lender
      agrees not to vote for any plan of reorganization in any bankruptcy
      proceeding of Borrower or any Guarantor that would not give effect to the
      payment provisions in Section 3.03.

            (d) The Tranche B Lenders irrevocably consent and direct that all
      Obligations owing to the Tranche A Lenders shall be paid in full prior to
      Borrower or any Guarantor making any payment on any Obligations owing to
      the Tranche B Lenders, except such payments as are expressly permitted by
      this Section 3.03. Without the prior written consent of the Tranche A
      Majority Lenders, the Borrower and the Guarantors will not make, and the
      Tranche B Lenders will not accept or receive, any payment or benefit in
      cash, by setoff or otherwise, directly or indirectly, on account of
      principal, interest or any other amounts owing on any of the Obligations
      owing to the Tranche B Lenders, except such payments as are expressly
      permitted herein, until the Tranche A Lenders shall have no obligations
      hereunder to the Borrower or any Guarantor including, without limitation,

                                       35
<PAGE>
      any obligation to loan money or issue Letters of Credit. Should any Lender
      receive any money with respect to the Obligations, it will be paid to the
      Administrative Agent to be applied in accordance with the procedures and
      priorities set forth in Section 3.03.

                                   ARTICLE IV

                PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

      Section 4.01 Payments. Except to the extent otherwise provided herein, all
payments of principal, interest and other amounts to be made by the Borrower
under this Agreement, the Notes and the Letter of Credit Agreements shall be
made in Dollars, in immediately available funds, to the Administrative Agent at
such account as the Administrative Agent shall specify by notice to the Borrower
from time to time, not later than 12:00 noon Charlotte, North Carolina time on
the date on which such payments shall become due (each such payment made after
such time on such due date to be deemed to have been made on the next succeeding
Business Day). Such payments shall be made without (to the fullest extent
permitted by applicable law) defense, set-off or counterclaim. Each payment
received by the Administrative Agent under this Agreement or any Note for
account of a Lender shall be paid promptly to such Lender in immediately
available funds. Except as otherwise provided in the definition of "Interest
Period", if the due date of any payment under this Agreement or any Note would
otherwise fall on a day which is not a Business Day such date shall be extended
to the next succeeding Business Day and interest shall be payable for any
principal so extended for the period of such extension. At the time of each
payment to the Administrative Agent of any principal of or interest on any
borrowing, the Borrower shall notify the Administrative Agent of the Loans to
which such payment shall apply. In the absence of such notice the Administrative
Agent may specify the Loans to which such payment shall apply, but to the extent
possible such payment or prepayment will be applied first to the Loans comprised
of Base Rate Loans.

      Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided
herein each Tranche A Lender agrees that: (i) each borrowing from the Tranche A
Lenders under Section 2.01 and each continuation and conversion under Section
2.02 shall be made from the Tranche A Lenders pro rata in accordance with their
Tranche A Percentage Share, each payment of commitment fee under Section 2.04(a)
shall be made for account of the Tranche A Lenders pro rata in accordance with
their Tranche A Percentage Share, and each termination or reduction of the
amount of the Tranche A Aggregate Maximum Credit Amounts under Section 2.03(b)
shall be applied to the Commitment of each Tranche A Lender, pro rata according
to the amounts of its respective Commitment; (ii) each payment of principal of
Tranche A Loans by the Borrower shall be made for account of the Tranche A
Lenders pro rata in accordance with the respective unpaid principal amount of
the Tranche A Loans held by the Tranche A Lenders; (iii) each payment of
interest on Tranche A Loans by the Borrower shall be made for account of the
Tranche A Lenders pro rata in accordance with the amounts of interest due and
payable to the respective Tranche A Lenders; and (iv) each reimbursement by the
Borrower of disbursements under Letters of Credit shall be made for account of
the Issuing Bank or, if funded by the Tranche A Lenders, pro rata for the
account of the Tranche A Lenders, in accordance with the amounts of
reimbursement obligations due and payable to each respective Tranche A Lender.

                                       36
<PAGE>
      Except to the extent otherwise provided herein, each Tranche B Lender
agrees that: (i) each borrowing from the Tranche B Lenders under Section 2.01
shall be made from the Tranche B Lenders pro rata in accordance with their
Tranche B Percentage Share, each payment of commitment fees under Section
2.04(a)(ii) shall be made for account of the Tranche B Lenders pro rata in
accordance with their Tranche B Percentage Share, and each termination or
reduction of the amount of the Tranche B Aggregate Maximum Credit Amounts under
Section 2.03(b) shall be applied to the Tranche B Commitment of each Tranche B
Lender, pro rata according to the amounts of its respective Tranche B
Commitment; (ii) each payment of principal of Tranche B Loans by the Borrower
shall be made for account of the Tranche B Lenders pro rata in accordance with
the respective unpaid principal amount of the Tranche B Loans held by the
Tranche B Lenders and (iii) each payment of interest on Tranche B Loans by the
Borrower shall be made for account of the Tranche B Lenders pro rata in
accordance with the amounts of interest due and payable to the respective
Tranche B Lenders.

      Section 4.03 Computations. Interest on LIBOR Loans, interest on Fixed Rate
Loans and commitment fees shall be computed on the basis of a year of 360 days
and actual days elapsed (including the first day but excluding the last day)
occurring in the period for which such interest is payable, unless such
calculation would exceed the Highest Lawful Rate, in which case interest shall
be calculated on the per annum basis of a year of 365 or 366 days, as the case
may be. Interest on Base Rate Loans shall be computed on the basis of a year of
365 or 366 days, as the case may be, and actual days elapsed (including the
first day but excluding the last day) occurring in the period for which such
interest is payable.

      Section 4.04 Non-receipt of Funds by the Administrative Agent. Unless the
Administrative Agent shall have been notified by a Lender or the Borrower prior
to the date on which such notifying party is scheduled to make payment to the
Administrative Agent (in the case of a Lender) of the proceeds of a Loan or a
payment under a Letter of Credit to be made by it hereunder or (in the case of
the Borrower) a payment to the Administrative Agent for account of one or more
of the Lenders hereunder (such payment being herein called the "Required
Payment"), which notice shall be effective upon receipt, that it does not intend
to make the Required Payment to the Administrative Agent, the Administrative
Agent may assume that the Required Payment has been made and may, in reliance
upon such assumption (but shall not be required to), make the amount thereof
available to the intended recipient(s) on such date and, if such Lender or the
Borrower (as the case may be) has not in fact made the Required Payment to the
Administrative Agent, the recipient(s) of such payment shall, on demand, repay
to the Administrative Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Administrative Agent until, but excluding,
the date the Administrative Agent recovers such amount at a rate per annum
which, for any Lender as recipient, will be equal to the Federal Funds Rate, and
for the Borrower as recipient, will be equal to the Base Rate plus the
Applicable Margin.

      Section 4.05 Set-off, Sharing of Payments, Etc.

            (a) The Borrower agrees that, in addition to (and without limitation
      of) any right of set-off, bankers' lien or counterclaim a Lender may
      otherwise have, each Lender shall have the right and be entitled (after
      consultation with the Administrative Agent), at

                                       37
<PAGE>
      its option, to offset balances held by it or by any of its Affiliates for
      account of the Borrower or any Guarantor at any of its offices, in Dollars
      or in any other currency, against any principal of or interest on any of
      such Lender's Loans, or any other amount payable to such Lender hereunder,
      which is not paid when due after the passage of any applicable grace
      periods (regardless of whether such balances are then due to the
      Borrower), in which case it shall promptly notify the Borrower and the
      Administrative Agent thereof, provided that such Lender's failure to give
      such notice shall not affect the validity thereof.

            (b) If any Lender shall obtain payment of any principal of or
      interest on any Loan made by it to the Borrower under this Agreement (or
      reimbursement as to any Letter of Credit) through the exercise of any
      right of set-off, banker's lien or counterclaim or similar right or
      otherwise, and, as a result of such payment, such Lender shall have
      received a greater portion of the principal or interest (or reimbursement)
      then due hereunder by the Borrower to such Lender than the portion
      received by any other Lenders, it shall promptly (i) notify the
      Administrative Agent and each other Lender thereof and (ii) purchase from
      such other Lenders participations in (or, if and to the extent specified
      by such Lender, direct interests in) the Loans (or participations in
      Letters of Credit) made by such other Lenders (or in interest due thereon,
      as the case may be) in such amounts, and make such other adjustments from
      time to time as shall be equitable, to the end that all the Lenders shall
      share the benefit of such excess payment (net of any expenses which may be
      incurred by such Lender in obtaining or preserving such excess payment) in
      accordance with the unpaid principal and/or interest on the Loans held by
      each of the Lenders (or reimbursements of Letters of Credit). To such end
      all the Lenders shall make appropriate adjustments among themselves (by
      the resale of participations sold or otherwise) if such payment is
      rescinded or must otherwise be restored. The Borrower agrees that any
      Lender so purchasing a participation (or direct interest) in the Loans
      made by other Lenders (or in interest due thereon, as the case may be) may
      exercise all rights of set-off, banker's lien, counterclaim or similar
      rights with respect to such participation as fully as if such Lender were
      a direct holder of Loans (or Letters of Credit) in the amount of such
      participation. Nothing contained herein shall require any Lender to
      exercise any such right or shall affect the right of any Lender to
      exercise, and retain the benefits of exercising, any such right with
      respect to any other indebtedness or obligation of the Borrower. If under
      any applicable bankruptcy, insolvency or other similar law, any Lender
      receives a secured claim in lieu of a set-off to which this Section 4.05
      applies, such Lender shall, to the extent practicable, exercise its rights
      in respect of such secured claim in a manner consistent with the rights of
      the Lenders entitled under this Section 4.05 to share the benefits of any
      recovery on such secured claim.

            (c) The provisions of this Section 4.05 are in all ways subject to
      the provisions of Section 3.03.

      Section 4.06 Taxes.

            (a) Payments Free and Clear. Any and all payments by the Borrower
      hereunder shall be made, in accordance with Section 4.01, free and clear
      of and without

                                       38
<PAGE>
      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 Lender, the Issuing Bank and the
      Administrative Agent, taxes imposed on its income, and franchise or
      similar taxes imposed on it, by (i) any jurisdiction (or political
      subdivision thereof) of which the Administrative Agent, the Issuing Bank
      or such Lender, as the case may be, is a citizen or resident or in which
      such Lender has an Applicable Lending Office, (ii) the jurisdiction (or
      any political subdivision thereof) in which the Administrative Agent, the
      Issuing Bank or such Lender is organized, or (iii) any jurisdiction (or
      political subdivision thereof) in which such Lender, the Issuing Bank or
      the Administrative Agent is presently doing business which taxes are
      imposed solely as a result of doing business in such jurisdiction (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 to the Lenders, the Issuing Bank or
      the Administrative Agent (i) the sum payable shall be increased by the
      amount necessary so that after making all required deductions (including
      deductions applicable to additional sums payable under this Section 4.06)
      such Lender, the Issuing Bank or the Administrative Agent (as the case may
      be) shall receive 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
      taxing authority or other Governmental Authority in accordance with
      applicable law.

            (b) Other Taxes. In addition, to the fullest extent permitted by
      applicable law, the Borrower agrees to pay any present or future stamp or
      documentary taxes or any other excise or property taxes, charges or
      similar levies that arise from any payment made hereunder or from the
      execution, delivery or registration of, or otherwise with respect to, this
      Agreement or any Security Instrument (hereinafter referred to as "Other
      Taxes").

            (c) INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
      LAW, THE BORROWER WILL INDEMNIFY EACH LENDER AND THE ISSUING BANK AND THE
      ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES AND OTHER TAXES
      (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED BY ANY
      GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 4.06) PAID BY
      SUCH LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT (ON THEIR BEHALF
      OR ON BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY
      (INCLUDING PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM OR WITH
      RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY
      OR LEGALLY ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR
      LEGALLY ASSERTED AND SUCH LENDER'S PAYMENT OF SUCH TAXES OR OTHER TAXES
      WAS THE RESULT OF ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. ANY PAYMENT
      PURSUANT TO SUCH INDEMNIFICATION SHALL BE MADE WITHIN THIRTY (30) DAYS
      AFTER THE DATE ANY LENDER, THE ISSUING BANK OR THE ADMINISTRATIVE AGENT,
      AS THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR. IF ANY LENDER, THE
      ISSUING BANK OR THE ADMINISTRATIVE AGENT RECEIVES A REFUND OR CREDIT IN
      RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH LENDER, ISSUING BANK OR
      THE ADMINISTRATIVE AGENT HAS RECEIVED PAYMENT FROM THE BORROWER IT SHALL
      PROMPTLY NOTIFY THE BORROWER OF SUCH REFUND OR CREDIT AND SHALL, IF

                                       39
<PAGE>
      NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN THIRTY (30) DAYS AFTER
      RECEIPT OF A REQUEST BY THE BORROWER (OR PROMPTLY UPON RECEIPT, IF THE
      BORROWER HAS REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT
      HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO THE BORROWER
      WITHOUT INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED), PROVIDED
      THAT THE BORROWER, UPON THE REQUEST OF SUCH LENDER, THE ISSUING BANK OR
      THE ADMINISTRATIVE AGENT, AGREES TO RETURN SUCH REFUND OR CREDIT (PLUS
      PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER OR THE ADMINISTRATIVE
      AGENT IN THE EVENT SUCH LENDER OR THE ADMINISTRATIVE AGENT IS REQUIRED TO
      REPAY SUCH REFUND OR CREDIT.

            (d) Lender Representations.

                  (i) Each Lender represents that it is either (1) not a
            "foreign person" as such term is defined in U.S. Treasury
            Regulations Section 1.1441-1(c)(2) or (2) it is 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 (A) under an applicable provision of a tax
            convention to which the United States of America is a party or (B)
            because it is acting through a branch, agency or office in the
            United States of America and any payment to be received by it
            hereunder is effectively connected with a trade or business in the
            United States of America. Each Lender that is a "foreign person" as
            such term is defined in U.S. Treasury Regulations Section
            1.441-1(c)(2) agrees to provide to the Borrower and the
            Administrative Agent on the Closing Date, or on the date of its
            delivery of the Assignment pursuant to which it becomes a Lender,
            and at such other times as required by United States law or as the
            Borrower or the Administrative Agent shall reasonably request, two
            accurate and complete original signed copies of either (A) Internal
            Revenue Service Form W-8ECI (or successor form) certifying that all
            payments to be made to it hereunder will be effectively connected to
            a United States trade or business (the "Form W-8ECI Certification")
            or (B) Internal Revenue Service Form W-8BEN (or successor form)
            certifying that it is entitled to the benefit of a provision of a
            tax convention to which the United States of America is a party
            which completely exempts from United States withholding tax all
            payments to be made to it hereunder (the "Form W-8BEN
            Certification"). In addition, each Lender agrees that if it
            previously filed a Form W-8ECI Certification, it will deliver to the
            Borrower and the Administrative Agent a new Form W-8ECI
            Certification prior to the first payment date occurring in each of
            its subsequent taxable years; and if it previously filed a Form
            W-8BEN Certification, it will deliver to the Borrower and the
            Administrative Agent a new certification prior to the first payment
            date falling in the third year following the previous filing of such
            certification. Each Lender also agrees to deliver to the Borrower
            and the Administrative Agent such other or supplemental forms as may
            at any time be required as a result of changes in applicable law or
            regulation in order to confirm or maintain in effect its entitlement
            to exemption from United States withholding tax on any payments
            hereunder, provided that the circumstances of such Lender at the
            relevant time and applicable laws permit it to do so. If a Lender
            determines, as a result of any

                                       40
<PAGE>
            change in either (i) a Governmental Requirement or (ii) its
            circumstances, that it is unable to submit any form or certificate
            that it is obligated to submit pursuant to this Section 4.06, or
            that it is required to withdraw or cancel any such form or
            certificate previously submitted, it shall promptly notify the
            Borrower and the Administrative Agent of such fact. If a Lender is
            organized under the laws of a jurisdiction outside the United States
            of America, unless the Borrower and the Administrative Agent have
            received a Form W-8BEN Certification or Form W-8ECI Certification
            satisfactory to them indicating that all payments to be made to such
            Lender hereunder are not subject to United States withholding tax,
            the Borrower shall withhold taxes from such payments at the
            applicable statutory rate. Each Lender agrees to indemnify and hold
            harmless the Borrower or Administrative Agent, as applicable, from
            any United States taxes, penalties, interest and other expenses,
            costs and losses incurred or payable by (i) the Administrative Agent
            as a result of such Lender's failure to submit any form or
            certificate that it is required to provide pursuant to this Section
            4.06 or (ii) the Borrower or the Administrative Agent as a result of
            their reliance on any such form or certificate which such Lender has
            provided to them pursuant to this Section 4.06.

                  (ii) For any period with respect to which a Lender has failed
            to provide the Borrower with the form required pursuant to this
            Section 4.06, if any, (other than if such failure is due to a change
            in a Governmental Requirement occurring subsequent to the date on
            which a form originally was required to be provided), such Lender
            shall not be entitled to indemnification under Section 4.06 with
            respect to taxes imposed by the United States which taxes would not
            have been imposed but for such failure to provide such forms;
            provided, however, that if a Lender, which is otherwise exempt from
            or subject to a reduced rate of withholding tax, becomes subject to
            taxes because of its failure to deliver a form required hereunder,
            the Borrower shall take such steps as such Lender shall reasonably
            request to assist such Lender to recover such taxes.

                  (iii) Any Lender claiming any additional amounts payable
            pursuant to this Section 4.06 shall use reasonable efforts
            (consistent with legal and regulatory restrictions) to file any
            certificate or document requested by the Borrower or the
            Administrative Agent or to change the jurisdiction of its Applicable
            Lending Office or to contest any tax imposed if the making of such a
            filing or change or contesting such tax would avoid the need for or
            reduce the amount of any such additional amounts that may thereafter
            accrue and would not, in the sole determination of such Lender, be
            otherwise disadvantageous to such Lender.

            (e) To the extent that any payments made or received under this
      Section 4.06 constitute interest that would be in excess of the Highest
      Lawful Rate, the Borrower shall not make, and no Lender shall receive, any
      such payment.

      Section 4.07 Disposition of Proceeds. Certain of the Security Instruments
contain an assignment by the Borrower and the Guarantors, as the case may be,
unto and in favor of the Agent for the benefit of the Lenders of all Hydrocarbon
production and all proceeds attributable

                                       41
<PAGE>
thereto which may be produced from or allocated to the Mortgaged Oil and Gas
Properties, and further provides in general for the application of such proceeds
to the satisfaction of the Obligations and any other obligations described
therein and secured thereby. Notwithstanding the assignment contained in such
Security Instruments, until the occurrence of an Event of Default, the Lenders
agree that they will neither notify the purchaser or purchasers of such
production nor take any other action to cause such proceeds to be remitted to
the Lenders, but the Lenders will instead permit such proceeds to be paid to the
Borrower and the Guarantors, as the case may be.

                      CAPITAL ADEQUACY AND YIELD PROTECTION

      Section 5.01 Additional Costs.

            (a) LIBOR Regulations, etc. The Borrower shall pay directly to each
      Tranche A Lender from time to time such amounts as such Lender may
      determine to be necessary to compensate such Lender for any costs which it
      determines are attributable to its making or maintaining of any LIBOR
      Loans or issuing or participating in Letters of Credit hereunder or its
      obligation to make any LIBOR Loans or issue or participate in any Letters
      of Credit hereunder, or any reduction in any amount receivable by such
      Lender hereunder in respect of any of such LIBOR Loans, Letters of Credit
      or such obligation (such increases in costs and reductions in amounts
      receivable being herein called "Additional Costs"), resulting from any
      Regulatory Change which: (i) changes the basis of taxation of any amounts
      payable to such Lender under this Agreement or any Note in respect of any
      of such LIBOR Loans or Letters of Credit (other than taxes imposed on the
      overall net income of such Lender or of its Applicable Lending Office for
      any of such LIBOR Loans by the jurisdiction in which such Lender has its
      principal office or Applicable Lending Office); or (ii) imposes or
      modifies any reserve, special deposit, minimum capital, capital ratio or
      similar requirements relating to any extensions of credit or other assets
      of, or any deposits with or other liabilities of such Lender, or the
      Commitment or Loans of such Lender or the London interbank market; or
      (iii) imposes any other condition affecting this Agreement or any Note (or
      any of such extensions of credit or liabilities) or such Lender's
      Commitment or Loans. Each Tranche A Lender will notify the Administrative
      Agent and the Borrower of any event occurring after the Closing Date which
      will entitle such Lender to compensation pursuant to this Section 5.01(a)
      as promptly as practicable after it obtains knowledge thereof and
      determines to request such compensation, and will designate a different
      Applicable Lending Office for the Loans of such Lender affected by such
      event if such designation will avoid the need for, or reduce the amount
      of, such compensation and will not, in the sole opinion of such Lender, be
      disadvantageous to such Lender, provided that such Lender shall have no
      obligation to so designate an Applicable Lending Office located in the
      United States. If any Tranche A Lender requests compensation from the
      Borrower under this Section 5.01(a), the Borrower may, by notice to such
      Lender, suspend the obligation of such Lender to make additional Loans of
      the Type with respect to which such compensation is requested until the
      Regulatory Change giving rise to such request ceases to be in effect (in
      which case the provisions of Section 5.04 shall be applicable).

                                       42

                  (b) Regulatory Change. Without limiting the effect of the
         provisions of Section 5.01(a), in the event that at any time (by reason
         of any Regulatory Change or any other circumstances arising after the
         Closing Date affecting (A) any Tranche A Lender, (B) the London
         interbank market or (C) such Tranche A Lender's position in such
         market), the LIBOR Rate, as determined in good faith by such Lender,
         will not adequately and fairly reflect the cost to such Lender of
         funding its LIBOR Loans, then, if such Lender so elects, by notice to
         the Borrower and the Administrative Agent, the obligation of such
         Lender to make additional LIBOR Loans shall be suspended until such
         Regulatory Change or other circumstances ceases to be in effect (in
         which case the provisions of Section 5.04 shall be applicable).

                  (c) Capital Adequacy. Without limiting the effect of the
         foregoing provisions of this Section 5.01 (but without duplication),
         the Borrower shall pay directly to any Tranche A Lender from time to
         time on request such amounts as such Lender may reasonably determine to
         be necessary to compensate such Lender or its parent or holding company
         for any costs which it determines are attributable to the maintenance
         by such Lender or its parent or holding company (or any Applicable
         Lending Office), pursuant to any Governmental Requirement following any
         Regulatory Change, of capital in respect of its Commitment, its Note,
         or its Loans or any interest held by it in any Letter of Credit, such
         compensation to include, without limitation, an amount equal to any
         reduction of the rate of return on assets or equity of such Lender or
         its parent or holding company (or any Applicable Lending Office) to a
         level below that which such Lender or its parent or holding company (or
         any Applicable Lending Office) could have achieved but for such
         Governmental Requirement. Such Tranche A Lender will notify the
         Borrower that it is entitled to compensation pursuant to this Section
         5.01(c) as promptly as practicable after it determines to request such
         compensation.

                  (d) Compensation Procedure. Any Tranche A Lender notifying the
         Borrower of the incurrence of Additional Costs under this Section 5.01
         shall in such notice to the Borrower and the Administrative Agent set
         forth in reasonable detail the basis and amount of its request for
         compensation. Determinations and allocations by each Tranche A Lender
         for purposes of this Section 5.01 of the effect of any Regulatory
         Change pursuant to Section 5.01(a) or (b), or of the effect of capital
         maintained pursuant to Section 5.01(c), on its costs or rate of return
         of maintaining Loans or its obligation to make Loans or issue Letters
         of Credit, or on amounts receivable by it in respect of Loans or
         Letters of Credit, and of the amounts required to compensate such
         Lender under this Section 5.01, shall be conclusive and binding for all
         purposes, provided that such determinations and allocations are made on
         a reasonable basis. Any request for additional compensation under this
         Section 5.01 shall be paid by the Borrower within thirty (30) days of
         the receipt by the Borrower of the notice described in this Section
         5.01(d).

         Section 5.02 Limitation on LIBOR Loans. Anything herein to the contrary
notwithstanding, if, on or prior to the determination of any LIBOR Rate for any
Interest Period:

                  (a) the Administrative Agent determines (which determination
         shall be conclusive, absent manifest error) that quotations of interest
         rates for the relevant

                                       43
<PAGE>
         deposits referred to in the definition of "LIBOR Rate" in Section 1.02
         are not being provided in the relevant amounts or for the relevant
         maturities for purposes of determining rates of interest for LIBOR
         Loans as provided herein; or

                  (b) the Administrative Agent determines (which determination
         shall be conclusive, absent manifest error) that the relevant rates of
         interest referred to in the definition of "LIBOR Rate" in Section 1.02
         upon the basis of which the rate of interest for LIBOR Loans for such
         Interest Period is to be determined are not sufficient to adequately
         cover the cost to the Tranche A Lenders of making or maintaining LIBOR
         Loans;

then the Administrative Agent shall give the Borrower prompt notice thereof, and
so long as such condition remains in effect, the Tranche A Lenders shall be
under no obligation to make additional LIBOR Loans.

         Section 5.03 Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Tranche A Lender or its
Applicable Lending Office to honor its obligation to make or maintain LIBOR
Loans hereunder, then such Lender shall promptly notify the Borrower thereof and
such Lender's obligation to make LIBOR Loans shall be suspended until such time
as such Lender may again make and maintain LIBOR Loans (in which case the
provisions of Section 5.04 shall be applicable).

         Section 5.04 Base Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03.
If the obligation of any Tranche A Lender to make LIBOR Loans shall be suspended
pursuant to Sections 5.01, 5.02 or 5.03 ("Affected Loans"), all Affected Loans
which would otherwise be made by such Lender shall be made instead as Base Rate
Loans (and, if an event referred to in Section 5.01(b) or Section 5.03 has
occurred and such Lender so requests by notice to the Borrower, all Affected
Loans of such Lender then outstanding shall be automatically converted into Base
Rate Loans on the date specified by such Lender in such notice) and, to the
extent that Affected Loans are so made as (or converted into) Base Rate Loans,
all payments of principal which would otherwise be applied to such Lender's
Affected Loans shall be applied instead to its Base Rate Loans.

         Section 5.05 Compensation. The Borrower shall pay to each Tranche A
Lender within thirty (30) days of receipt of written request of such Lender
(which request shall set forth, in reasonable detail, the basis for requesting
such amounts and which shall be conclusive and binding for all purposes provided
that such determinations are made on a reasonable basis), such amount or amounts
as shall compensate it for any loss, cost, expense or liability which such
Lender determines are attributable to:

                  (a) any payment, prepayment or conversion of a LIBOR Loan
         properly made by such Lender or the Borrower for any reason (including,
         without limitation, the acceleration of the Loans pursuant to Section
         10.01) on a date other than the last day of the Interest Period for
         such Loan; or

                  (b) any failure by the Borrower for any reason (including but
         not limited to, the failure of any of the conditions precedent
         specified in Article VI to be satisfied) to

                                       44
<PAGE>
         borrow, continue or convert a LIBOR Loan from such Lender on the date
         for such borrowing, continuation or conversion specified in the
         relevant notice given pursuant to Section 2.02(c).

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
which would have accrued on the principal amount so paid, prepaid or converted
or not borrowed for the period from the date of such payment, prepayment or
conversion or failure to borrow to the last day of the Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for such Loan
which would have commenced on the date specified for such borrowing) at the
applicable rate of interest for such Loan provided for herein over (ii) the
interest component of the amount such Lender would have bid in the London
interbank market for Dollar deposits of leading banks in amounts comparable to
such principal amount and with maturities comparable to such period (as
reasonably determined by such Lender).

         Section 5.06 Time Limit; Etc.

                  (a) Time Limited. Notwithstanding anything to the contrary
         contained in Sections 5.01 through 5.05, the Borrower shall not be
         required to reimburse or pay any costs or expenses to any Tranche A
         Lender as required by such sections which have accrued more than 180
         days prior to such Lender's giving notice to the Borrower that such
         Lender has suffered or incurred such costs or expenses.

                  (b) Non-Discriminatory Basis. None of the Tranche A Lenders
         shall be permitted to pass through to the Borrower costs and expenses
         under Sections 5.01 through 5.05 which are not also passed through by
         such Lender to other customers of such Lender similarly situated when
         such customer is subject to documents containing similar provisions as
         those contained in such Sections.

         Section 5.07 Replacement Tranche A Lenders.

                  (a) Terminated Tranche A Lenders. If any Tranche A Lender has
         notified the Borrower and the Administrative Agent of its incurring
         Additional Costs under Section 5.01 or has required the Borrower to
         make payments for Taxes under Section 4.06 or it is unable to make
         LIBOR Loans under Section 5.03, then the Borrower may, unless such
         Tranche A Lender has notified the Borrower and the Administrative Agent
         that the circumstances giving rise to such notice no longer apply,
         terminate, in whole but not in part, the Commitment of any Lender
         (other than the Administrative Agent) (the "Terminated Lender") at any
         time upon five (5) Business Days' prior written notice to the
         Terminated Lender and the Administrative Agent (such notice referred to
         herein as a "Notice of Termination").

                  (b) Replacement Tranche A Lenders. In order to effect the
         termination of the Commitment of the Terminated Lender, the Borrower
         shall: (i) obtain an agreement with one or more Lenders to increase
         their Tranche A Commitment and/or (ii) request any one or more other
         banking institutions to become parties to this Agreement in place and
         instead of such Terminated Lender and agree to accept a Tranche A
         Commitment;

                                       45
<PAGE>
         provided, however, that such one or more other banking institutions are
         reasonably acceptable to the Administrative Agent and become parties by
         executing an Assignment (the lenders or other banking institutions that
         agree to accept in whole or in part the Tranche A Commitment of the
         Terminated Lender being referred to herein as the "Replacement
         Lenders"), such that the aggregate increased and/or accepted Tranche A
         Commitments of the Replacement Lenders under clauses (i) and (ii) above
         equal the Tranche A Commitment of the Terminated Lender.

                  (c) Content of Notice of Termination. The Notice of
         Termination shall include the name of the Terminated Lender, the date
         the termination will occur (the "Lender Termination Date"), and the
         Replacement Lender or Replacement Lenders to which the Terminated
         Lender will assign its Tranche A Commitment and, if there will be more
         than one Replacement Lender, the portion of the Terminated Lender's
         Tranche A Commitment to be assigned to each Replacement Lender.

                  (d) Effecting Termination. On the Lender Termination Date, (i)
         the Terminated Lender shall by execution and delivery of an Assignment
         assign its Tranche A Commitment to the Replacement Lender or
         Replacement Lenders (pro rata, if there is more than one Replacement
         Lender, in proportion to the portion of the Terminated Lender's Tranche
         A Commitment to be assigned to each Replacement Lender) indicated in
         the Notice of Termination and shall assign to the Replacement Lender or
         Replacement Lenders each of its Tranche A Loans (if any) then
         outstanding and participation interests in Letters of Credit (if any)
         then outstanding pro rata as aforesaid), (ii) the Terminated Lender
         shall endorse its Note, payable without recourse, representation or
         warranty to the order of the Replacement Lender or Replacement Lenders
         (pro rata as aforesaid), (iii) the Replacement Lender or Replacement
         Lenders shall purchase the Note held by the Terminated Lender (pro rata
         as aforesaid) at a price equal to the unpaid principal amount thereof
         plus interest and facility and other fees accrued and unpaid to the
         Lender Termination Date, and (iv) the Replacement Lender or Replacement
         Lenders will thereupon (pro rata as aforesaid) succeed to and be
         substituted in all respects for the Terminated Lender with like effect
         as if becoming a Lender pursuant to the terms of Section 12.06(b), and
         the Terminated Lender will have the rights and benefits of an assignor
         under Section 12.06(b). To the extent not in conflict, the terms of
         Section 12.06(b) shall supplement the provisions of this Section
         5.06(d). For each assignment made under this Section 5.06, the
         Replacement Lender shall pay to the Administrative Agent the processing
         fee provided for in Section 12.06(b). The Borrower will be responsible
         for the payment of any breakage costs associated with termination and
         Replacement Lenders, as set forth in Section 5.05.

                                   ARTICLE VI

         Section 6.02 Initial and Subsequent Loans and Letters of Credit. The
obligation of the Lenders to make Loans to the Borrower upon the occasion of
each borrowing hereunder and to issue, renew, extend or reissue Letters of
Credit for the account of the Borrower (including the Initial Funding) is
subject to the further conditions precedent that, as of the date of such Loans
and after giving effect thereto:

                                       48
<PAGE>
                  (a) no Default shall exist;

                  (b) no Material Adverse Effect shall have occurred;

                  (c) the representations and warranties made by the Borrower in
         Article VII and in the Security Instruments shall be true on and as of
         the date of the making of such Loans or issuance, renewal, extension or
         reissuance of a Letter of Credit with the same force and effect as if
         made on and as of such date and following such new borrowing, except to
         the extent such representations and warranties are expressly limited to
         an earlier date or, with respect to Tranche A Loans, the Tranche A
         Majority Lenders may expressly consent in writing to the contrary, or,
         with respect to Tranche B Loans, the Tranche B Majority Lenders may
         expressly consent in writing to the contrary; and

                  (d) No borrowing shall be made which, after giving effect to
         such borrowing and the use of proceeds therefrom, would result in the
         Availability being less than $20,085,000.00 unless the 2002
         Subordinated Notes have been (or contemporaneously therewith will be)
         either repaid or renewed and extended in compliance with the terms and
         provisions of this Agreement.

         Each request for a borrowing or issuance, renewal, extension or
reissuance of a Letter of Credit by the Borrower hereunder shall constitute a
certification by the Borrower to the effect set forth in Section 6.02(c) (both
as of the date of such notice and, unless the Borrower otherwise notifies the
Administrative Agent prior to the date of and immediately following such
borrowing or issuance, renewal, extension or reissuance of a Letter of Credit as
of the date thereof).

         Section 6.03 Conditions Precedent for the Benefit of Lenders. All
conditions precedent to the obligations of the Tranche A Lenders to make any
Tranche A Loan or to issue, renew or extend any Letter of Credit are imposed
hereby solely for the benefit of the Tranche A Lenders, and no other Person
(including, without limitation, any Tranche B Lender) may require satisfaction
of any such condition precedent or be entitled to assume that the Tranche A
Lenders will refuse to make any Tranche A Loan or issue, renew or extend any
Letter of Credit in the absence of strict compliance with such conditions
precedent. All conditions precedent to the obligations of the Tranche B Lenders
to make any Tranche B Loan are imposed hereby solely for the benefit of the
Tranche B Lenders, and no other Person (including, without limitation, any
Tranche A Lender) may require satisfaction of any such condition precedent or be
entitled to assume that the Tranche B Lenders will refuse to make any Tranche B
Loan in the absence of strict compliance with such conditions precedent.

         Section 6.04 No Waiver. No waiver of any condition precedent shall
preclude the Administrative Agent or the applicable Lenders from requiring such
condition to be met prior to making any subsequent Loan or preclude the
applicable Lenders from thereafter declaring that the failure of the Borrower to
satisfy such condition precedent constitutes a Default.

                                  ARTICLE VII

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Administrative Agent and
the Lenders that (each representation and warranty herein is given as of the
Closing Date and shall be deemed repeated and reaffirmed on the dates of each
borrowing and issuance, renewal, extension or reissuance of a Letter of Credit
as provided in Section 6.02):

         Section 7.01 Corporate Existence. Each of the Borrower and each
Guarantor: (i) is a corporation duly organized, legally existing and in good
standing under the laws of the jurisdiction of its incorporation; (ii) has all
requisite corporate power, and has all material governmental licenses,
authorizations, consents and approvals necessary to own its assets and carry on
its business as now being or as proposed to be conducted; and (iii) is qualified
to do business in all jurisdictions in which the nature of the business
conducted by it makes such qualification necessary and where failure so to
qualify would have a Material Adverse Effect.

         Section 7.02 Financial Condition. The audited consolidated balance
sheet of the Borrower and its Consolidated Subsidiaries as at December 31, 2001,
and the related consolidated statement of income, stockholders' equity and cash
flow of the Borrower and its Consolidated Subsidiaries for the fiscal year ended
on said date, with the opinion thereon of Arthur Andersen LLP heretofore
furnished to the Administrative Agent and the unaudited consolidated balance
sheet of the Borrower and its Consolidated Subsidiaries as at March 31, 2002,
and their related consolidated statements of income, stockholders' equity and
cash flow of the Borrower and its Consolidated Subsidiaries for the three-month
period ended on such date heretofore furnished to the Administrative Agent, are
complete and correct in all material respects and fairly present the
consolidated financial condition of the Borrower and its Consolidated
Subsidiaries as at said dates and the results of its operations for the fiscal
year and the three month period ending on said dates, all in accordance with
GAAP, as applied on a consistent basis (subject, in the case of the interim
financial statements, to normal year-end adjustments). Neither the Borrower nor
any Subsidiary has on the Closing Date any material Debt, contingent
liabilities, liabilities for taxes, unusual forward or long-term commitments or
unrealized or anticipated losses from any unfavorable commitments, except as
referred to or reflected or provided for in the Financial Statements or in
Schedule 7.02. As of the Closing Date, since December 31, 2001, there has been
no change or event having a Material Adverse Effect.

         Section 7.03 Litigation. Except as disclosed to the Lenders in Schedule
7.03 hereto, at the Closing Date there is no litigation, legal, administrative
or arbitral proceeding, investigation or other action of any nature pending or,
to the knowledge of the Borrower threatened against or affecting the Borrower or
any Subsidiary which involves the possibility of any judgment or liability
against the Borrower or any Subsidiary not fully covered by insurance (except
for normal deductibles).

         Section 7.04 No Breach. Neither the execution and delivery of the Loan
Documents, nor compliance with the terms and provisions hereof will conflict
with or result in a breach of, or require any consent which has not been
obtained as of the Closing Date under, the respective

                                       50
<PAGE>
charter or by-laws of the Borrower or any Subsidiary, or any Governmental
Requirement or any agreement or instrument to which the Borrower or any
Subsidiary is a party or by which it is bound or to which it or its Properties
are subject, or constitute a default under any such agreement or instrument, or
result in the creation or imposition of any Lien upon any of the revenues or
assets of the Borrower or any Subsidiary pursuant to the terms of any such
agreement or instrument other than the Liens created by the Loan Documents.

         Section 7.05 Authority. The Borrower and each Guarantor have all
necessary corporate power and authority to execute, deliver and perform its
obligations under the Loan Documents to which it is a party; and the execution,
delivery and performance by the Borrower and each Guarantor of the Loan
Documents to which it is a party, have been duly authorized by all necessary
corporate action on its part; and the Loan Documents constitute the legal, valid
and binding obligations of the Borrower and each Guarantor, enforceable in
accordance with their terms.

         Section 7.06 Approvals. No authorizations, approvals or consents of,
and no filings or registrations with, any Governmental Authority are necessary
for the execution, delivery or performance by the Borrower or any Guarantor of
the Loan Documents or for the validity or enforceability thereof, except for the
recording and filing of the Security Instruments as required by this Agreement.

         Section 7.07 Use of Loans. The proceeds of the Loans shall be used by
Borrower and its wholly owned Subsidiaries to make capital contributions to CPOC
as described in Section 2.02(f) and for (i) the acquisition by them of Oil and
Gas Properties, (ii) exploration and development of their Oil and Gas
Properties, (iii) working capital for their operations and (iv) their other
general corporate purposes. None of the Guarantors or the Borrower is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose, whether immediate, incidental or ultimate, of buying or
carrying margin stock (within the meaning of Regulation T, U or X of the Board
of Governors of the Federal Reserve System) and no part of the proceeds of any
Loan hereunder will be used to buy or carry any margin stock.

         Section 7.08 ERISA.

                  (a) The Borrower, each Subsidiary and each ERISA Affiliate
         have complied in all material respects with ERISA and, where
         applicable, the Code regarding each Plan.

                  (b) Each Plan is, and has been, maintained in substantial
         compliance with ERISA and, where applicable, the Code.

                  (c) No act, omission or transaction has occurred which could
         result in imposition on the Borrower, any Subsidiary or any ERISA
         Affiliate (whether directly or indirectly) of (i) either a civil
         penalty assessed pursuant to section 502(c), (i) or (l) of ERISA or a
         tax imposed pursuant to Chapter 43 of Subtitle D of the Code or (ii)
         breach of fiduciary duty liability damages under section 409 of ERISA.

                  (d) No Plan (other than a defined contribution plan) or any
         trust created under any such Plan has been terminated since September
         2, 1974. No liability to the PBGC (other than for the payment of
         current premiums which are not past due) by the Borrower,

                                       51
<PAGE>
         any Subsidiary or any ERISA Affiliate has been or is expected by the
         Borrower, any Subsidiary or any ERISA Affiliate to be incurred with
         respect to any Plan. No ERISA Event with respect to any Plan has
         occurred.

                  (e) Full payment when due has been made of all amounts which
         the Borrower, any Subsidiary or any ERISA Affiliate is required under
         the terms of each Plan or applicable law to have paid as contributions
         to such Plan, and 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.

                  (f) The actuarial present value of the benefit liabilities
         under each Plan which is subject to Title IV of ERISA does not, as of
         the end of the Borrower's most recently ended fiscal year, exceed the
         current value of the assets (computed on a plan termination basis in
         accordance with Title IV of ERISA) of such Plan allocable to such
         benefit liabilities. The term "actuarial present value of the benefit
         liabilities" shall have the meaning specified in section 4041 of ERISA.

                  (g) None of the Borrower, any Subsidiary or any ERISA
         Affiliate sponsors, maintains, or contributes to an employee welfare
         benefit plan, as defined in section 3(1) of ERISA, including, without
         limitation, any such plan maintained to provide benefits to former
         employees of such entities, that may not be terminated by the Borrower,
         a Subsidiary or any ERISA Affiliate in its sole discretion at any time
         without any material liability.

                  (h) None of the Borrower, any Subsidiary or any ERISA
         Affiliate sponsors, maintains or contributes to, or has at any time in
         the preceding six calendar years, sponsored, maintained or contributed
         to, any Multiemployer Plan.

                  (i) None of the Borrower, any Subsidiary or any ERISA
         Affiliate is required to provide security under section 401(a)(29) of
         the Code due to a Plan amendment that results in an increase in current
         liability for the Plan.

         Section 7.09 Taxes. Except as set out in Schedule 7.09, each of the
Borrower and its Subsidiaries has filed all United States Federal income tax
returns and all other tax returns which are required to be filed by them and
have paid all material taxes due pursuant to such returns or pursuant to any
assessment received by the Borrower or any Subsidiary. The charges, accruals and
reserves on the books of the Borrower and its Subsidiaries in respect of taxes
and other governmental charges are, in the opinion of the Borrower, adequate. No
tax lien has been filed and, to the knowledge of the Borrower, no claim is being
asserted with respect to any such tax, fee or other charge.

         Section 7.10 Titles, etc.

                  (a) Except as set out in Schedule 7.10, each of the Borrower
         and the Guarantors has good and defensible title to its material
         (individually or in the aggregate) Properties, free and clear of all
         Liens, except Liens permitted by Section 9.02. Except as set forth in
         Schedule 7.10, after giving full effect to the Excepted Liens, the
         Borrower owns the net interests in production attributable to the
         Hydrocarbon Interests reflected in

                                       52
<PAGE>
         the most recently delivered Reserve Report and the ownership of such
         Properties does not in any material respect obligate the Borrower to
         bear the costs and expenses relating to the maintenance, development
         and operations of each such Property in an amount in excess of the
         working interest of each Property set forth in the most recently
         delivered Reserve Report. All information contained in the most
         recently delivered 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 the Guarantors are valid
         and subsisting, in full force and effect and 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
         agreement, which would affect in any material respect the conduct of
         the business of the Borrower and the Guarantors.

                  (c) The rights, Properties and other assets presently owned,
         leased or licensed by the Borrower and the Guarantors including,
         without limitation, all easements and rights of way, include all
         rights, Properties and other assets reasonably necessary to permit the
         Borrower and the Guarantors to conduct their business in all material
         respects in the same manner as its business has been conducted prior to
         the Closing Date.

                  (d) All of the assets and Properties of the Borrower and the
         Guarantors which are reasonably necessary for the operation of its
         business are in good working condition and are maintained in accordance
         with customary industry standards.

         Section 7.11 No Material Misstatements. No written information,
statement, exhibit, certificate, document or report furnished to the
Administrative Agent and the Lenders (or any of them) by the Borrower or any
Subsidiary in connection with the negotiation of this Agreement contained any
material misstatement of fact or omitted to state a material fact or any fact
necessary to make the statement contained therein not materially misleading in
the light of the circumstances in which made and with respect to the Borrower
and its Subsidiaries taken as a whole. There is no fact peculiar to the Borrower
or any Subsidiary which has a Material Adverse Effect or in the future is
reasonably likely to have (so far as the Borrower can now foresee) a Material
Adverse Effect and which has not been disclosed in writing to the Administrative
Agent and the Lenders by or on behalf of the Borrower or any Subsidiary prior
to, or on, the Closing Date in connection with the transactions contemplated
hereby.

         Section 7.12 Investment Company Act. Neither the Borrower nor any
Subsidiary is an "investment company" or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

         Section 7.13 Public Utility Holding Company Act. Neither the Borrower
nor any Subsidiary is a "holding company," or a "subsidiary company" of a
"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company," or a "public utility" within the meaning of the
Public Utility Holding Company Act of 1935, as amended.

         Section 7.14 Subsidiaries. Except as set forth on Schedule 7.14, as of
the Closing Date the Borrower has no Subsidiaries.

         Section 7.15 Location of Business and Offices. The Borrower's principal
place of business and chief executive offices are located at the address stated
on the signature page of this Agreement. The principal place of business and
chief executive office of each Subsidiary are located at the addresses stated on
Schedule 7.14.

         Section 7.16 Defaults. Neither the Borrower nor any Subsidiary is in
default nor has any event or circumstance occurred which, but for the expiration
of any applicable grace period or the giving of notice, or both, would
constitute a default under any material agreement or instrument to which the
Borrower or any Subsidiary is a party or by which the Borrower or any Subsidiary
is bound which default would have a Material Adverse Effect. No Default
hereunder has occurred and is continuing.

         Section 7.17 Environmental Matters. Except (i) as provided in Schedule
7.17 or (ii) as would not have a Material Adverse Effect (or with respect to
(c), (d) and (e) below, where the failure to take such actions would not have a
Material Adverse Effect):

                  (a) Neither any Property of the Borrower or any Subsidiary nor
         the operations conducted thereon violate any order or requirement of
         any court or Governmental Authority or any Environmental Laws;

                  (b) Without limitation of clause (a) above, no Property of the
         Borrower or any Subsidiary nor the operations currently conducted
         thereon or, to the best knowledge of the Borrower, by any prior owner
         or operator of such Property or operation, are in violation of or
         subject to any existing, pending or threatened action, suit,
         investigation, inquiry or proceeding by or before any court or
         Governmental Authority or to any remedial obligations under
         Environmental Laws;

                  (c) All notices, permits, licenses or similar authorizations,
         if any, required to be obtained or filed in connection with the
         operation or use of any and all Property of the Borrower and each
         Subsidiary, including without limitation past or present treatment,
         storage, disposal or release of a hazardous substance or solid waste
         into the environment, have been duly obtained or filed, and the
         Borrower and each Subsidiary are in compliance with the terms and
         conditions of all such notices, permits, licenses and similar
         authorizations;

                  (d) All hazardous substances, solid waste, and oil and gas
         exploration and production wastes, if any, generated at any and all
         Property of the Borrower or any Subsidiary have in the past been
         transported, treated and disposed of in accordance with Environmental
         Laws and so as not to pose an imminent and substantial endangerment to
         public health or welfare or the environment, and, to the best knowledge
         of the Borrower, all such transport carriers and treatment and disposal
         facilities have been and are operating in compliance with Environmental
         Laws and so as not to pose an imminent and substantial endangerment to
         public health or welfare or the environment, and are not the

                                       54
<PAGE>
         subject of any existing, pending or threatened action, investigation or
         inquiry by any Governmental Authority in connection with any
         Environmental Laws;

                  (e) The Borrower has taken all steps reasonably necessary to
         determine and has determined that no hazardous substances, solid waste,
         or oil and gas exploration and production wastes, have been disposed of
         or otherwise released and there has been no threatened release of any
         hazardous substances on or to any Property of the Borrower or any
         Subsidiary except in compliance with Environmental Laws and so as not
         to pose an imminent and substantial endangerment to public health or
         welfare or the environment;

                  (f) To the extent applicable, all Property of the Borrower and
         each Subsidiary currently satisfies all design, operation, and
         equipment requirements imposed by the OPA or scheduled as of the
         Closing Date to be imposed by OPA during the term of this Agreement,
         and the Borrower does not have any reason to believe that such
         Property, to the extent subject to OPA, will not be able to maintain
         compliance with the OPA requirements during the term of this Agreement;
         and

                  (g) Neither the Borrower nor any Subsidiary has any known
         contingent liability in connection with any release or threatened
         release of any oil, hazardous substance or solid waste into the
         environment.

         Section 7.18 Compliance with the Law. Neither the Borrower nor any
Subsidiary has violated any Governmental Requirement or failed to obtain any
license, permit, franchise or other governmental authorization necessary for the
ownership of any of its Properties or the conduct of its business, which
violation or failure would have (in the event such violation or failure were
asserted by any Person through appropriate action) a Material Adverse Effect.
Except for such acts or failures to act as would not have a Material Adverse
Effect, the Oil and Gas Properties (and properties unitized therewith) have been
maintained, operated and developed in a good and workmanlike manner and in
conformity with all applicable laws and all rules, regulations and orders of all
duly constituted authorities having jurisdiction and in conformity with the
provisions of all leases, subleases or other contracts comprising a part of the
Hydrocarbon Interests and other contracts and agreements forming a part of the
Oil and Gas Properties; specifically in this connection, (i) after the Closing
Date, no Oil and Gas Property is subject to having allowable production reduced
below the full and regular allowable (including the maximum permissible
tolerance) because of any overproduction (whether or not the same was
permissible at the time) prior to the Closing Date and (ii) none of the wells
comprising a part of the Oil and Gas Properties (or properties unitized
therewith) are deviated from the vertical more than the maximum permitted by
applicable laws, regulations, rules and orders, and such wells are, in fact,
bottomed under and are producing from, and the well bores are wholly within, the
Oil and Gas Properties (or in the case of wells located on properties unitized
therewith, such unitized properties).

         Section 7.19 Insurance. Schedule 7.19 attached hereto contains an
accurate and complete description of all material policies of fire, liability,
workmen's compensation and other forms of insurance owned or held by the
Borrower and each Subsidiary. All such policies are in full force and effect,
all premiums with respect thereto covering all periods up to and including the
date of the closing have been paid, and no notice of cancellation or termination
has been

                                       55
<PAGE>
received with respect to any such policy. Such policies are sufficient for
compliance with all requirements of law and of all material agreements to which
the Borrower or any Subsidiary is a party; are valid, outstanding and
enforceable policies; provide adequate insurance coverage in at least such
amounts and against at least such risks (but including in any event public
liability) as are customarily insured against in the same general area by
companies engaged in the same or a similar business for the assets and
operations of the Borrower and each Subsidiary; will remain in full force and
effect through the respective dates set forth in Schedule 7.19 without the
payment of additional premiums; and will not in any way be affected by, or
terminate or lapse by reason of, the transactions contemplated by this
Agreement. Schedule 7.19 identifies all material risks, if any, which the
Borrower and its Subsidiaries and their respective Board of Directors or
officers have designated as being self insured. Neither the Borrower nor any
Subsidiary has been refused any insurance with respect to its assets or
operations, nor has its coverage been limited below usual and customary policy
limits, by an insurance carrier to which it has applied for any such insurance
or with which it has carried insurance during the last three years.

         Section 7.20 Hedging Agreements. Schedule 7.20 sets forth, as of the
Closing Date, a true and complete list of all Hedging Agreements (including
commodity price swap agreements, forward agreements (for terms in excess of
thirty days) or contracts of sale which provide for prepayment for deferred
shipment or delivery of oil, gas or other commodities) of the Borrower and each
Subsidiary, the material terms thereof (including the type, term, effective
date, termination date and notional amounts or volumes), the net mark to market
value thereof, all credit support agreements relating thereto (including any
margin required or supplied), and the counter party to each such agreement.

         Section 7.21 Restriction on Liens. Neither the Borrower nor any of the
Guarantors is a party to any agreement or arrangement (other than this Agreement
and the Security Instruments), or subject to any order, judgment, writ or
decree, which either restricts or purports to restrict its ability to grant
Liens to other Persons on or in respect of their respective assets or
Properties.

         Section 7.22 Material Agreements. Set forth on Schedule 7.22 hereto is
a complete and correct list of all material agreements, leases, indentures,
purchase agreements, obligations in respect of letters of credit, guarantees,
joint venture agreements, and other instruments in effect or to be in effect as
of the Closing Date (other than Hedging Agreements and agreements relating to
Debt of the type described in clause (iii) in the definition of Debt or clause
(vii) in the definition of Debt to the extent relating to primary obligations of
the type described in clause (iii) in the definition of Debt) providing for,
evidencing, securing or otherwise relating to any Debt of the Borrower or any of
its Subsidiaries, and all obligations of the Borrower or any of its Subsidiaries
to issuers of surety or appeal bonds issued for account of the Borrower or any
such Subsidiary, and such list correctly sets forth the names of the debtor or
lessee and creditor or lessor with respect to the Debt or lease obligations
outstanding or to be outstanding and the Property subject to any Lien securing
such Debt or lease obligation. The Borrower has heretofore delivered to the
Administrative Agent a complete and correct copy of all such material credit
agreements, indentures, purchase agreements, contracts, letters of credit,
guarantees, joint venture agreements, or other instruments, including any
modifications or supplements thereto, as in effect on the Closing Date, which
the Administrative Agent has requested.

         Section 7.23 Gas Imbalances. Except as set forth on Schedule 7.23 or on
the most recent certificate delivered pursuant to Section 8.07(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, in the aggregate, five percent (5%) or more of the quarterly production
from Hydrocarbons produced from the Borrower's Oil and Gas Properties at some
future time without then or thereafter receiving full payment therefor.

                                  ARTICLE VIII

                              AFFIRMATIVE COVENANTS

         The Borrower covenants and agrees that, so long as any of the
Commitments are in effect and until payment in full of all Loans hereunder, all
interest thereon and all other amounts payable by the Borrower hereunder:

         Section 8.01 Reporting Requirements. The Borrower shall deliver, or
shall cause to be delivered, to the Administrative Agent with sufficient copies
of each for the Lenders:

                  (a) Annual Financial Statements. As soon as available and in
         any event within 90 days after the end of each fiscal year of the
         Borrower, the audited consolidated statement of income, stockholders'
         equity, changes in financial position and cash flows of the Borrower
         and its Consolidated Subsidiaries for such fiscal year, and the related
         consolidated balance sheet of the Borrower and its Consolidated
         Subsidiaries as at the end of such fiscal year, and setting forth in

         Material Adverse Effect: (i) all Property of the Borrower and its

         redetermination requested by the Tranche A Majority Lenders or the
         Borrower pursuant to Section 2.08(d)), the Borrower shall provide such
         Reserve Report with an "as of" date as required by the Majority Tranche
         A Lenders as soon as possible, but in any event no later than 30 days

                  (c) With the delivery of each Reserve Report, the Borrower
         shall provide to the Administrative Agent and the Lenders, a
         certificate from a Responsible Officer certifying that, to the best of

         Liens permitted by Section 9.02, (iii) except as set forth on an
         exhibit to the certificate, on a net basis there are no gas imbalances,
         take or pay or other prepayments with respect to its Oil and Gas

         Borrower to deliver Hydrocarbons produced from such Oil and Gas
         Properties at some future time without then or thereafter receiving
         full payment therefor, (iv) none of its Oil and Gas Properties listed
         in the immediately prior Reserve Report as having proved reserves have
         been sold since the date of the last Borrowing Base determination
         except as set forth on an exhibit to the certificate, which certificate
         shall list all of such Oil and Gas Properties sold and in such detail
         as reasonably required by the Administrative Agent, (v) attached to the
         certificate is a list of all Persons disbursing proceeds to the
         Borrower from its Mortgaged Oil and Gas Properties and (vi) except as
         set forth on a schedule attached to the certificate all of the Oil and

         Section 8.08 Title Information.

                  (a) Delivery. On or before the delivery to the Administrative
         Agent and the Lenders of each Reserve Report required by Section
         8.07(a), the Borrower will deliver

                                       62
<PAGE>
         title information in form and substance acceptable to the
         Administrative Agent covering enough of the Mortgaged Oil and Gas
         Properties evaluated by such Reserve Report that were not included in
         the immediately preceding Reserve Report, so that the Administrative
         Agent shall have received together with title information previously
         delivered to the Administrative Agent, satisfactory title information
         on at least seventy percent (70%) of the value of the Mortgaged Oil and
         Gas Properties evaluated by such Reserve Report.

                  (b) Cure of Title Defects. The Borrower shall cure any title
         defects or exceptions which are not Excepted Liens raised by such
         information, or substitute acceptable Oil and Gas Properties of an
         equivalent value, with no title defects or exceptions except for
         Excepted Liens, within 60 days after a request by the Administrative
         Agent or the Lenders to cure such defects or exceptions.

                  (c) Failure to Cure Title Defects. If the Borrower is unable
         to cure any title defect requested by the Administrative Agent or the
         Lenders to be cured within the 60- day period or the Borrower does not
         comply with the requirements to provide acceptable title information
         covering seventy percent (70%) of the value of the Oil and Gas
         Properties evaluated in the most recent Reserve Report and included in
         the determination of the then current Borrowing Base, such default
         shall not be a Default or an Event of Default, but instead the
         Administrative Agent and the Lenders shall have the right to exercise
         the following remedy in their sole discretion from time to time, after
         September 30, 2002, and any failure to so exercise this remedy at any
         time shall not be a waiver as to future exercise of the remedy by the
         Administrative Agent or the Lenders. To the extent that the
         Administrative Agent or the Lenders are not satisfied with title to any
         Mortgaged Oil and Gas Property after the time period in Section 8.08(b)
         has elapsed, such unacceptable Mortgaged Oil and Gas Property shall not
         count towards the seventy percent (70%) requirement, and the
         Administrative Agent may send a notice to the Borrower and the Lenders
         that the then outstanding Borrowing Base shall be reduced by an amount
         as determined by all of the Tranche A Lenders to cause the Borrower to
         be in compliance with the requirement to provide acceptable title
         information on seventy percent (70%) of the value of the Mortgaged Oil
         and Gas Properties included in the determination of the Borrowing Base.
         This new Borrowing Base shall become effective immediately after
         receipt of such notice.

         Section 8.09 Collateral.

                  (a) Collateral. The Obligations shall be secured by a
         perfected first priority Lien (subject only to Liens permitted under
         Section 9.02 entitled to priority under applicable law or under Section
         9.02) granted to the Administrative Agent for the benefit of the
         Beneficiaries in (i) the Oil and Gas Properties of the Borrower and the
         Guarantors, whether now owned or hereafter acquired, pursuant to the
         terms of the Security Instruments to which they are parties, and which
         compose at least 95% of the value of the Oil and Gas Properties
         described in the most recent Reserve Report and (ii) all of the
         accounts receivable, inventory, equipment, contract rights, general
         intangibles and equity interests in all Subsidiaries of the Borrower
         and each Guarantor pursuant to the terms of the Security Instruments to
         which they are parties.

                  (b) Lien in Acquired Oil and Gas Properties. Subject to the
         provisions of Section 8.09(a), should the Borrower acquire any
         additional Oil and Gas Properties or additional interests in its
         existing Oil and Gas Properties, the Borrower will at the same time
         grant to the Administrative Agent as security for the Obligations a
         first-priority Lien interest (subject only to Excepted Liens) on the
         Borrower's interest in any Oil and Gas Properties not already subject
         to a Lien of the Security Instruments, which Lien will be created and

and if a Borrowing Base Deficiency results therefrom, the Borrower shall
concurrently with completing such Transfer, make a prepayment of the outstanding

circumstances, if any, pertaining to such Property where such violations or
remedial obligations would have a Material Adverse Effect.

         Section 9.18 Transactions with Affiliates. Neither the Borrower nor any
Subsidiary will enter into any transaction, including, without limitation, any
purchase, sale, lease or exchange of Property or the rendering of any service,
with any Affiliate unless such transactions are otherwise permitted under this
Agreement, are in the ordinary course of its business and are upon fair and
reasonable terms no less favorable to it than it would obtain in a comparable
arm's length transaction with a Person not an Affiliate.

         Section 9.19 Intentionally Deleted.

         Section 9.20 Subsidiaries. The Borrower shall not and shall not permit

permitted under Section 9.02 with respect to the Property covered by such Liens
only) which in any way prohibits or restricts the granting, conveying, creation
or imposition of any Lien on any of its Property or restricts any Guarantor from
paying dividends to the Borrower, or which requires the consent of or notice to
other Persons in connection therewith.

         Section 9.23 Subordinated Debt. Neither the Borrower nor any Guarantor
shall make any voluntary prepayment in respect of any Subordinated Debt or the
Existing Subordinated Debt, nor will they make any other payment thereon that
would not be allowed under the subordination provisions of any Subordinated Debt
or the Existing Subordinated Debt. The Borrower will not amend, supplement or
otherwise modify any instruments evidencing, or agreements relating to or
executed in connection with, any Existing Subordinated Debt, in any manner which
would have the effect of (i) accelerating the timing or amount of any scheduled
payments of principal or interest thereon, (ii) increasing the rate of interest
payable thereon or (iii) resulting in a Material Adverse Effect.

         Section 9.24 Duke Credit Agreement. Without the prior written consent

or Event of Default has occurred and is continuing at the time Borrower or any
of its Subsidiaries enters into any Permitted Medusa Transaction, the entering
into and carrying out of such Permitted Medusa Transaction shall be allowed
hereunder and shall not in itself constitute a breach of, non-compliance with,
or Default or Event of Default under this Agreement or any other Loan Document.

                                   ARTICLE XI

                            THE ADMINISTRATIVE AGENT

         Section 11.01 Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its agent
hereunder and under the Security Instruments with such powers as are
specifically delegated to the Administrative Agent by the terms of this
Agreement and the Security Instruments, together with such other powers as are
reasonably incidental thereto. The Administrative Agent (which term as used in
this sentence and in Section 11.05 and the first sentence of Section 11.06 shall
include reference to its Affiliates and its and its Affiliates' officers,
directors, employees, attorneys, accountants, experts and agents): (i) shall
have no duties or responsibilities except those expressly set forth in the Loan
Documents, and shall not by reason of the Loan Documents be a trustee or
fiduciary for any Lender; (ii) makes no representation or warranty to any Lender
and shall not be responsible to the Lenders for any recitals, statements,
representations or warranties contained in this Agreement, or in any certificate
or other document referred to or provided for in, or received by any of them
under, this Agreement, or for the value, validity, effectiveness, genuineness,
execution, effectiveness, legality, enforceability or sufficiency of this
Agreement, any Note or any other document referred to or provided for herein or
for any failure by the Borrower or any other Person (other than the
Administrative Agent) to perform any of its obligations hereunder or thereunder
or for the existence, value, perfection or priority of any collateral security
or the financial or other condition of the Borrower, its Subsidiaries or any
other obligor or guarantor; (iii) except pursuant to Section 11.07 shall not be
required to initiate or conduct any litigation or collection proceedings
hereunder; and (iv) shall not be responsible for any action taken or omitted to
be taken by it hereunder or under any other document or instrument referred to
or provided for herein or in connection herewith including its own ordinary
negligence, except for its own gross negligence or willful misconduct. The
Administrative Agent may employ agents, accountants, attorneys and experts and
shall not be responsible for the negligence or misconduct of any such agents,
accountants, attorneys or experts selected by it in good faith or any action
taken or omitted to be taken in good faith by it in accordance with the advice
of such agents, accountants, attorneys or experts. The Administrative Agent may
deem and treat the payee of any Note as the holder thereof for all purposes
hereof unless and until a written notice of the assignment or transfer thereof
permitted hereunder shall have been filed with the Administrative Agent. The
Administrative Agent is authorized to release any collateral that is permitted
to be sold or released pursuant to the terms of the Loan Documents.

         Section 11.02 Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely upon any certification, notice or other
communication (including any thereof by

                                       77
<PAGE>
telephone, telex, telecopier, telegram or cable) believed by it to be genuine
and correct and to have been signed or sent by or on behalf of the proper Person
or Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Administrative Agent.

         Section 11.03 Defaults. The Administrative Agent shall not be deemed to
have knowledge of the occurrence of a Default (other than the non-payment of
principal of or interest on Loans or of fees or failure to reimburse for Letter
of Credit drawings) unless the Administrative Agent has received notice from a
Lender or the Borrower specifying such Default and stating that such notice is a
"Notice of Default." In the event that the Administrative Agent receives such a
notice of the occurrence of a Default, the Administrative Agent shall give
prompt notice thereof to the Lenders. In the event of a payment Default, the
Administrative Agent shall give each Lender prompt notice of each such payment
Default.

         Section 11.04 Rights as a Lender. With respect to its Commitments and
the Loans made by it and its participation in the issuance of Letters of Credit,
Wachovia (and any successor acting as Administrative Agent) in its capacity as a
Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as the
Administrative Agent, and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Administrative Agent in its individual
capacity. Wachovia (and any successor acting as Administrative Agent) and its
Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to and generally engage in any kind of banking, trust
or other business with the Borrower (and any of its Affiliates) as if it were

AND (B) NO TRANCHE B LENDER SHALL INDEMNIFY THE ISSUING BANK FOR ANY MATTERS

         Section 11.06 Non-Reliance on Administrative Agent and other Lenders.
Each Lender acknowledges and agrees that it has, independently and without
reliance on the Administrative Agent or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis of the Borrower and its decision to enter into this Agreement, and that
it will, independently and without reliance upon the Administrative Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in
taking or not taking action under this Agreement. The Administrative Agent shall
not be required to keep itself informed as to the performance or observance by
the Borrower of this Agreement, the Notes, the Security Instruments or any other
document referred to or provided for herein or to inspect the properties or
books of the Borrower. Except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Borrower (or any
of its Affiliates) which may come into the possession of the Administrative
Agent or any of its Affiliates. In this regard, each Lender acknowledges that
Winstead Sechrest & Minick P.C., is acting in this transaction as special
counsel to the Administrative Agent only, except to the extent otherwise
expressly stated in any legal opinion or any Loan Document. Each Lender will
consult with its own legal counsel to the extent that it deems necessary in
connection with the Loan Documents and the matters contemplated therein. Except
for breach of the express terms of the Loan Documents, or the gross negligence
or willful misconduct of the Administrative Agent or any of the Tranche A
Lenders, neither the Administrative Agent nor the Tranche A Lenders,
respectively, shall have any liability to the Tranche B Lenders of any kind with
respect to the manner or time in which the Administrative Agent or Tranche A
Lenders elect to exercise (or refrain from exercising) any of their rights or
remedies under the Loan Documents with respect to the Tranche A Loans, the
Tranche B Loans, the LC Exposure, Borrower, any Guarantor, or any of Borrower's
or any Guarantor's assets. The Tranche B Lenders acknowledge and agree that the
Tranche A Lenders may exercise any of their rights and remedies under this
Agreement and the other Loan Documents in any way and to any extent provided for
in the Loan Documents, without any implied obligations to the Tranche B Lenders.
Similarly, except for breach of the express terms of the Loan Documents, or the
gross negligence or willful misconduct of any of the Tranche B Lenders, the
Tranche B Lenders shall have no liability to the Tranche A Lenders of any kind
with respect to the manner or time in which the Tranche B Lenders elect to
exercise (or refrain from exercising) any of their rights or remedies under the
Loan Documents with respect to the Tranche B Loans, Borrower, any Guarantor, or
any of Borrower's or any Guarantor's assets. The Tranche A Lenders acknowledge
and agree that the Tranche B Lenders may exercise any of their rights and
remedies under this Agreement and the other Loan Documents in any way and to any
extent provided for in the Loan Documents, without any implied obligations to
the Tranche A Lenders. The Tranche B Lenders waive any right the Tranche B
Lenders might otherwise have to require a marshalling of any assets or security
held for all or any part of the Obligations owed to the Tranche A Lenders or,
except as otherwise provided for herein, to direct or affect the manner or
timing with which the Tranche A Lenders enforce any of their rights and remedies
with respect to the Collateral.

         Section 11.07 Action by Administrative Agent. Except for action or
other matters expressly required of the Administrative Agent hereunder, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall (i) receive written instructions from
the Majority Lenders (or the Tranche A Majority Lenders or the Tranche B
Majority Lenders as expressly required by Section 10.02 or all of the Lenders as
expressly required by Section 12.04) specifying the action to be taken, and (ii)
be indemnified to its satisfaction by the Lenders against any and all liability
and expenses which may be incurred by it by reason of taking or continuing to
take any such action. The instructions of the Majority Lenders (or the Tranche A
Majority Lenders or the Tranche B Majority Lenders as expressly required by
Section 10.02 or all of the Lenders as expressly required by Section 12.04) and
any action taken or failure to act pursuant thereto by the Administrative Agent
shall be binding on all of the Lenders. If a Default has occurred and is
continuing, the Administrative Agent shall take such action with respect to such
Default as shall be directed by the Majority Lenders, the Tranche A Majority
Lenders or the Tranche B Majority Lenders, as applicable (or all of the Lenders
as required by Section 12.04) in the written instructions (with indemnities)
described in this Section 11.07, provided that, unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default as it shall deem advisable in
the best interests of the Lenders. In no event, however, shall the
Administrative Agent be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement and the Loan Documents or applicable law.

         Section 11.08 Resignation or Removal of Administrative Agent. Subject
to the appointment and acceptance of a successor Administrative Agent as
provided below, the Administrative Agent may resign at any time by giving notice
thereof to the Lenders and the Borrower, and the Administrative Agent may be
removed at any time with or without cause by the Majority Lenders. Upon any such
resignation or removal, the Majority Lenders shall have the right to appoint a
successor Administrative Agent with the consent of the Borrower (such consent
not to be unreasonably withheld). If no successor Administrative Agent shall
have been so appointed by the Majority Lenders and shall have accepted such
appointment within thirty (30) days after the retiring Administrative Agent's
giving of notice of resignation or the Majority Lenders' removal of the retiring
Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent with the consent of the
Borrower (such consent not to be unreasonably withheld). Upon the acceptance of
such appointment hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder. After any retiring Administrative Agent's resignation or
removal hereunder as Administrative Agent, the provisions of this Article XI and
Section 12.03 shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as the Administrative
Agent.

                                  MISCELLANEOUS

         Section 12.01 Waiver. No failure on the part of the Administrative
Agent or any Lender to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power or privilege under any of the Loan
Documents shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege under any of the Loan Documents
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law.

                  (b) No Indemnified Party may settle any claim to be
         indemnified without the consent of the Borrower, such consent not to be
         unreasonably withheld; provided, that the Borrower may not reasonably
         withhold consent to any settlement that an Indemnified Party proposes,
         if the Borrower does not have the financial ability to pay all its
         obligations outstanding and asserted against the Borrower at that time,
         including the maximum potential claims against the Indemnified Party to
         be indemnified pursuant to this Section 12.03.

<PAGE>

                  (c) In the case of any indemnification hereunder, the
         Administrative Agent or Lender, as appropriate shall give notice to the
         Borrower of any such claim or demand being made against the Indemnified
         Party and the Borrower shall have the non-exclusive right to join in
         the defense against any such claim or demand provided that if the
         Borrower provides a defense, the Indemnified Party shall bear its own
         cost of defense unless there is a conflict between the Borrower and
         such Indemnified Party.

                  (d) THE FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED
         PARTIES NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND
         OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN
         AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES
         OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF
         ONE OR MORE OF THE INDEMNIFIED PARTIES OR BY REASON OF STRICT LIABILITY
         IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNIFIED PARTIES. TO
         THE EXTENT THAT AN INDEMNIFIED PARTY IS FOUND TO HAVE COMMITTED AN ACT
         OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, THIS CONTRACTUAL OBLIGATION
         OF INDEMNIFICATION SHALL CONTINUE BUT SHALL ONLY EXTEND TO THE PORTION
         OF THE CLAIM THAT IS DEEMED TO HAVE OCCURRED BY REASON OF EVENTS OTHER
         THAN THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE INDEMNIFIED
         PARTY.

                  (e) The Borrower's obligations under this Section 12.03 shall
         survive any termination of this Agreement and the payment of the Notes
         and shall continue thereafter in full force and effect.

                  (f) The Borrower shall pay any amounts due under this Section
         12.03 within thirty (30) days of the receipt by the Borrower of notice

Obligations outstanding under this Agreement, releases any guarantor of the
Obligations or releases all or substantially all of the collateral, reduces the
interest rate applicable to the Loans or the fees payable to the Lenders
generally, affects Section 2.03(a), this Section 12.04 or Section 12.06(a), or
modifies the definition of "Tranche A Majority Lenders, "Tranche B Majority
Lenders," or "Majority Lenders" shall be effective without consent of all
Lenders; (ii) no amendment, modification or waiver which increases the Maximum
Credit Amount of any Lender shall be effective without the consent of such
Lender; (iii) no amendment, modification or waiver which modifies the rights,
duties or obligations of the Administrative Agent shall be effective without the
consent of the Administrative Agent; (iv) no amendment which increases the
Borrowing Base shall be effective without the written consent of all the Tranche
A Lenders; (v) this Section 12.04 does not restrict or limit the application of
any other provision hereof that expressly authorizes particular Lenders to
consent to particular matters, such as the provisions of Sections 9.13(a),
9.14(a), and 9.15(a) which allow the Tranche A Majority Lenders to consent (if
they choose) to the Borrower's failure to comply with certain specified
financial requirements; and (vi) the Tranche B Lenders shall not, without all of
the Tranche A Lenders' prior written consent, settle any claim it now has or may
at any time

hereafter have against Borrower or any Guarantor at any time that any of the
Obligations to any of the Tranche A Lenders remain outstanding and/or any of the
Tranche A Lenders remain committed to extend any credit to Borrower, or any
Letters of Credit remain outstanding unless they have been fully cash
collateralized as required by Section 2.10 pursuant to documents in form and
substance satisfactory to the Administrative Agent.

         Section 12.05 Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

         Section 12.06 Assignments and Participations.

                  (a) The Borrower may not assign its rights or obligations
         hereunder or under the Notes or any Letters of Credit without the prior
         consent of all of the Lenders and the Administrative Agent.

                  (b) Any Lender may, upon the written consent of the
         Administrative Agent and, if no Event of Default has occurred and is
         continuing, the Borrower (which consent will not be unreasonably
         withheld), assign to one or more assignees all or a portion of its
         rights and obligations under this Agreement pursuant to an Assignment
         Agreement substantially in the form of Exhibit E-1 (for Tranche A
         Lenders) and Exhibit E-2 (for Tranche B Lenders) (an "Assignment");
         provided, however, that (i) any such assignment of a partial interest
         in a Note shall be in the amount of at least $5,000,000 or such lesser
         amount to which the Borrower has consented; (ii) the assignee or
         assignor shall pay to the Administrative Agent a processing and
         recordation fee of $3,500 for each assignment; and (iii) no consent of
         the Administrative Agent or the Borrower shall be required for any
         assignment by a Lender to any Lender or any nominee or Affiliate of any
         Lender. Any such assignment will become effective upon the execution
         and delivery to the Administrative Agent of the Assignment and the
         consent of the Administrative Agent and, if applicable, the Borrower.
         Promptly after receipt of an executed Assignment, the Administrative
         Agent shall send to the Borrower a copy of such executed Assignment.
         Upon receipt of such executed Assignment, the Borrower, will, at its
         own expense, execute and deliver new Notes to the assignor and/or
         assignee, as appropriate, in accordance with their respective interests
         as they appear. Upon the effectiveness of any assignment pursuant to
         this Section 12.06(b), the assignee will become a "Lender," if not
         already a "Lender," for all purposes of this Agreement and the Loan
         Documents. The assignor shall be relieved of its obligations hereunder
         to the extent of such assignment (and if the assigning Lender no longer
         holds any rights or obligations under this Agreement, such assigning
         Lender shall cease to be a "Lender" hereunder except that its rights
         under Sections 4.06, 5.01, 5.05 and 12.03 shall not be affected). The
         Administrative Agent will prepare on the last Business Day of each
         month during which an assignment has become effective pursuant to this
         Section 12.06(b), a new Annex I giving effect to all such assignments
         effected during such month, and will promptly provide the same to the
         Borrower and each of the Lenders.

                  (c) Each Lender may transfer, grant or assign participations
         in all or any part of such Lender's interests hereunder pursuant to
         this Section 12.06(c) to any Person, provided that: (i) such Lender
         shall remain a "Lender" for all purposes of this Agreement

                                       85
<PAGE>

         and the transferee of such participation shall not constitute a
         "Lender" hereunder; and (ii) no participant under any such
         participation shall have rights to approve any amendment to or waiver
         of any of the Loan Documents except to the extent such amendment or
         waiver would (x) forgive any principal owing on any Obligations or
         extend the final maturity of the Loans, (y) reduce the interest rate
         (other than as a result of waiving the applicability of any
         post-default increases in interest rates) or fees applicable to any of
         the Commitments or Loans or Letters of Credit in which such participant
         is participating, or postpone the payment of any thereof, or (z)
         release any guarantor of the Obligations or release all or
         substantially all of the collateral (except as provided in the Loan
         Documents) supporting any of the Commitments or Loans or Letters of
         Credit in which such participant is participating. In the case of any
         such participation, the participant shall not have any rights under
         this Agreement or any of the Security Instruments (the participant's
         rights against the granting Lender in respect of such participation to
         be those set forth in the agreement with such Lender creating such
         participation), and all amounts payable by the Borrower hereunder shall
         be determined as if such Lender had not sold such participation,
         provided that such participant shall be entitled to receive --------
         additional amounts under Article V on the same basis as if it were a
         Lender and be indemnified under Section 12.03 as if it were a Lender.
         In addition, each agreement creating any participation must include an
         agreement by the participant to be bound by the provisions of Section
         12.15.

                  (d) The Lenders may furnish any information concerning the
         Borrower in the possession of the Lenders from time to time to
         assignees and participants (including prospective assignees and
         participants); provided that, such Persons agree to be bound by the
         provisions of Section 12.15.

                  (e) Notwithstanding anything in this Section 12.06 to the
         contrary, any Lender may assign and pledge its Note to any Federal
         Reserve Bank. No such assignment and/or pledge shall release the
         assigning and/or pledging Lender from its obligations hereunder.

                  (f) Notwithstanding any other provisions of this Section
         12.06, no transfer or assignment of the interests or obligations of any
         Lender or any grant of participations therein shall be permitted if
         such transfer, assignment or grant would require the Borrower to file a
         registration statement with the SEC or to qualify the Loans under the
         "Blue Sky" laws of any state.

                  (g) Upon request of the Tranche B Lenders given at any time
         during the continuance of any Event of Default, the Tranche A Lenders
         shall assign to the Tranche B Lenders (or their nominee) the Tranche A
         Loans and the Tranche A Notes, in whole but not in part, for a purchase
         price equal to the principal and accrued interest plus all unpaid fees
         and expenses so assigned; provided, however, that the Borrower shall
         have cash collateralized an amount equal to the entire LC Exposure by
         executing such instruments and documents that any of the Tranche A
         Lenders shall request in an amount equal to the LC Exposure.

         Section 12.07 Invalidity. In the event that any one or more of the
provisions contained in any of the Loan Documents, the Letters of Credit, or the
Letter of Credit Agreements shall, for

                                       86
<PAGE>

any reason, be held invalid, illegal or unenforceable in any respect, such
invalidity, illegality or unenforceability shall not affect any other provision
of the Notes, this Agreement or any other Loan Document.

         Section 12.08 Counterparts. This Agreement may be executed in any
number of counterparts, all of which taken together shall constitute one and the
same instrument and any of the parties hereto may execute this Agreement by
signing any such counterpart.

"hereof," "hereunder" and other words of similar import when used in this
Agreement refer to this Agreement as a whole, and not to any particular article,

4.06, Article V, and Sections 11.05 and 12.03 shall survive the repayment of the
Loans and the termination of the Commitments. To the extent that any payments on
the Obligations or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, debtor in possession, receiver or other Person under any bankruptcy
law, common law or equitable cause, then to such extent, the Obligations so
satisfied shall be revived and continue as if such payment or proceeds had not
been received and the Administrative Agent's and the Lenders' Liens, security
interests, rights, powers and remedies under this Agreement and each Security
Instrument shall continue in full force and effect. In such event, each Security
Instrument shall be automatically reinstated and the Borrower shall take such
action as may be reasonably requested by the Administrative Agent and the
Lenders to effect such reinstatement.

                  (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND
         CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS, EXCEPT TO
         THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CHARGE

                                       87
<PAGE>

         INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER
         IS LOCATED. CH. 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN
         REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL
         NOT APPLY TO THIS AGREEMENT OR THE NOTES.

                  (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN
         DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF
         THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, AND,
         BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER HEREBY

         OTHERWISE HAVING JURISDICTION.

                  (c) THE BORROWER HEREBY IRREVOCABLY CONSENTS TO THE SERVICE OF
         PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR

         SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL
         DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES;

         TO ENFORCE THE FOREGOING WAIVERS, AND (IV) ACKNOWLEDGE THAT IT HAS BEEN
         INDUCED TO ENTER INTO THIS CREDIT AGREEMENT AND THE OTHER LOAN
         DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY,

         Section 12.14 Interest. It is the intention of the parties hereto that
each Lender shall conform strictly to usury laws applicable to it. Accordingly,
if the transactions contemplated hereby would be usurious as to any Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to such Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, it is agreed as follows: (i) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by such Lender under any
of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if
theretofore paid shall be credited by such Lender on the principal amount of the
Obligations (or, to the extent that the principal amount of the Obligations
shall have been or would thereby be paid in full, refunded by such Lender to the
Borrower); and (ii) in the event that the maturity of the Notes is accelerated
by reason of an election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest under
law applicable to any Lender may never include more than the maximum amount
allowed by such applicable law, and excess interest, if any, provided for in
this Agreement or otherwise shall be canceled automatically by such Lender as of
the date of such acceleration or prepayment and, if theretofore paid, shall be
credited by such Lender on the principal amount of the Obligations (or, to the
extent that the principal amount of the Obligations shall have been or would
thereby be paid in full, refunded by such Lender to the Borrower). All sums paid
or agreed to be paid to any Lender for the use, forbearance or detention of sums
due hereunder shall, to the extent permitted by law applicable to such Lender,
be amortized, prorated, allocated and spread throughout the full term of the
Loans evidenced by the Notes until payment in full so that the rate or amount of
interest on account of any Loans hereunder does not exceed the maximum amount
allowed by such applicable law. If at any time and from time to time (i) the
amount of interest payable to any Lender on any date shall be computed at the
Highest Lawful Rate applicable to such Lender pursuant to this Section 12.14 and
(ii) in respect of any subsequent interest computation period the amount of
interest otherwise payable to such Lender would be less than the amount of
interest payable to such Lender computed at the Highest Lawful Rate applicable
to such Lender, then the amount of interest payable to such Lender in respect of
such subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to such Lender until the total amount of interest
payable to such Lender shall equal the total amount of interest which would have
been payable to such Lender if the total amount of interest had been computed
without giving effect to this Section 12.14. To the extent that Chapter 303 of
the Texas Finance Code is relevant for the purpose of determining the Highest
Lawful Rate, such Lender elects to determine the applicable rate ceiling under
such Chapter by the weekly ceiling from time to time in effect.

         Section 12.15 Confidentiality. In the event that the Borrower or any
Subsidiary provides to the Administrative Agent or the Lenders confidential
information belonging to the Borrower or such Subsidiary, which the Borrower or
any Subsidiary shall designate in writing as "confidential", the Administrative
Agent and the Lenders 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

                                       89
<PAGE>

apply to such portions of the information which (i) are in the public domain,
(ii) hereafter become part of the public domain without the Administrative Agent
or the Lenders breaching their obligation of confidence to the Borrower, (iii)
are previously known by the Administrative Agent or the Lenders from some source
other than the Borrower, (iv) are hereafter developed by the Administrative
Agent or the Lenders without using the Borrower's information, (v) are hereafter
obtained by or available to the Administrative Agent or the Lenders 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 Governmental Requirement or to Persons
regulating the activities of the Administrative Agent or the Lenders, 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
Administrative Agent or a Lender may disclose any such information to any other
Lender, or any Affiliate of any Lender any independent petroleum engineers or
consultants, any independent certified public accountants, any legal counsel
employed by such Person in connection with this Agreement or any Security
Instrument, 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 Administrative Agent or the Lenders shall receive a confidentiality
agreement from the Person to whom such information is disclosed such that said
Person shall have the same obligation to maintain the confidentiality of such
information as is imposed upon the Administrative Agent or the Lenders
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 Administrative Agent and the Lenders arising by contract, agreement,
statute or law except as expressly stated in this Section 12.15.

         Section 12.16 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE SECURITY
INSTRUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS

AND THE SECURITY INSTRUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT
IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS
RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT
IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION
OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS ON THE BASIS THAT THE PARTY HAD
NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT
"CONSPICUOUS."

         Section 12.17 Hedging Agreement Substitution of Collateral. If the
Obligations are paid in full and this Agreement is terminated, the
Administrative Agent and the Lenders shall execute and deliver or cause to be
executed and delivered such instruments of satisfaction and reassignment as may
be appropriate in order to release all liens and security interests created by
the Security Instruments, provided, however, that in lieu of paying off any such
Obligations arising under any Hedging Agreement with any Lender or Affiliate of
any Lender, the Borrower may provide substitute credit support under a standard
form ISDA Credit Support Annex acceptable to such Lender (or its Affiliate) in
the form of a letter of credit or cash equivalents in an amount equal to 110% of
the then current exposure under such Hedging Agreement.

         Section 12.18 Amendment, Restatement and Rearrangement of Prior Debt.
The parties hereto agree that to the extent the Prior Debt is refinanced with
proceeds of Loans hereunder, this Agreement amends, restates and rearranges such
Prior Debt pursuant to the terms and conditions of this Agreement.

         Section 12.19 Obligations as Senior Indebtedness; Specified Senior
Indebtedness. It is the intent of all the parties hereto that all of the
Obligations arising under this Agreement and the other Loan Documents shall
constitute (and to the extent, if any, required are hereby designated by
Borrower to constitute) (i) "Senior Indebtedness" and Debt arising under the
"Senior Secured Credit Facility" as such terms are defined in the Duke Credit
Agreement, and (ii) "Senior Indebtedness" and "Specified Senior Indebtedness" as
such terms are defined in the indentures governing the Existing Subordinated
Debt. This Agreement and the other Loan Documents represent (i) the "Senior
Secured Credit Facility," as defined in the Duke Credit Agreement, and (ii) the
"Credit Facility" as defined in the indentures governing the Existing
Subordinated Debt. Notwithstanding the foregoing, the acknowledgment of intent
contained in this Section 12.19 shall not be deemed to modify or amend any
provision of this Agreement or any of the other Loan Documents.

AGREEMENT OF LIMITED PARTNERSHIP OF AIMCO PROPERTIES, L.P., dated as of May 14,
2002 (this "Amendment"), is being executed by AIMCO-GP, Inc., a Delaware

L.P., a Delaware limited partnership (the "Partnership"), pursuant to the
authority conferred on the General Partner by Section 7.3.C(7) of the Third
Amended and Restated Agreement of Limited Partnership of AIMCO Properties, L.P.,
dated as of July 29, 1994 (the "Agreement"). Capitalized terms used, but not
otherwise defined herein, shall have the respective meanings ascribed thereto in
the Agreement.

         WHEREAS, pursuant to Section 4.2.A of the Agreement, the General
Partner is authorized to cause the Partnership to issue Partnership Units with
such designations, preferences and relative, participating, optional or other
special rights, powers and duties as the General Partner shall determine and as
shall be set forth in a written document attached to and made an exhibit to the
Agreement; and

         WHEREAS, the General Partner has determined that it is in the best
interests of the Partnership to issue 5,000 units of a new class of Partnership
Units in consideration of capital contributions to the Partnership in the
aggregate amount of $1,066,000.

         NOW, THEREFORE, in consideration of the foregoing, and other good and

acknowledged, the parties hereto agree as follows:

         1. The Agreement is hereby amended by the addition of a new exhibit,
entitled "Exhibit KK," in the form attached hereto, which shall be attached to

         2. Each Person to whom the General Partner shall initially cause the
Partnership to issue any of the Partnership Units described on Exhibit KK shall
be admitted to the Partnership as a Limited Partner with the rights of holders
of the Partnership Units set forth on Exhibit KK. The General Partner shall
amend Exhibit A to the Agreement to reflect the admittance of each such Person
as a Limited Partner and the issuance of such Partnership Units to each such
Person.

         3. Except as specifically amended hereby, the terms, covenants,
provisions and conditions of the Agreement shall remain unmodified and continue
in full force and effect and, except as amended hereby, all of the terms,
covenants, provisions and conditions of the Agreement are hereby ratified and

                                     OF THE
                   CLASS V HIGH PERFORMANCE PARTNERSHIP UNITS
                            OF AIMCO PROPERTIES, L.P.

         1. NUMBER OF UNITS AND DESIGNATION.

         A class of Partnership Units is hereby designated as "Class V High
Performance Partnership Units," and the number of Partnership Units initially
constituting such class shall be five thousand (5,000), subject to adjustment at
the Class V High Performance Valuation Date, as provided in Section 3 hereof.

         2. DEFINITIONS.

         For purposes of this Partnership Unit Designation, the following terms
shall have the meanings indicated in this Section 2. Capitalized terms used and
not otherwise defined herein shall have the meanings assigned thereto in the
Agreement.

         "AIMCO EQUITY CAPITALIZATION" shall mean the quotient obtained by
dividing (i) the sum of the AIMCO Market Values for each trading day included in
the Measurement Period, by (ii) the number of trading days included in the
Measurement Period.

         "AIMCO MARKET VALUE" shall mean, for any date, the product of (i) the
number of REIT Shares and Partnership Units (other than Partnership Preferred
Units) outstanding as of the close of business on such date, multiplied by (ii)
the Value of a REIT Share on such date.

         "AIMCO TOTAL RETURN" shall mean the Total Return of the REIT Shares for
the Measurement Period; provided, however, that, for purposes of calculating the
security price of the REIT Shares (i) at the beginning of the Measurement
Period, such price shall be $45.19 and (ii) at the end of the Measurement
Period, such price shall be the average of the daily market prices for twenty
(20) consecutive trading days ending immediately prior to the Class V High
Performance Valuation Date. The market price for any such trading day shall be:

                  (a) if the REIT Shares are listed or admitted to trading on
         any securities exchange or The Nasdaq Stock Market's National Market
         System, the volume-weighted average of trading prices on such day, as
         reported by Bloomberg Financial Markets (or another reliable source
         selected by the General Partner), or if no trade takes place on such
         day, the average of the closing bid

                                      KK-1
<PAGE>

         and asked prices on such day, as reported in the principal consolidated
         transaction reporting system;

                  (b) if the REIT Shares are not listed or admitted to trading
         on any securities exchange or The Nasdaq Stock Market's National Market
         System, the last reported sale price on such day or, if no sale takes
         place on such day, the average of the closing bid and asked prices on
         such day, as reported by a reliable quotation source designated by the
         General Partner; or

                  (c) if the REIT Shares are not listed or admitted to trading
         on any securities exchange or The Nasdaq Stock Market's National Market
         System and no such last reported sale price or closing bid and asked
         prices are available, the average of the reported high bid and low
         asked prices on such day, as reported by a reliable quotation source
         designated by the General Partner, or if there shall be no bid and
         asked prices on such day, the average of the high bid and low asked
         prices, as so reported, on the most recent day (not more than ten (10)
         days prior to the date in question) for which prices have been so
         reported;

provided, however, that, if there are no bid and asked prices reported during
the ten (10) days prior to the date in question, the market price of the REIT
Shares shall be determined by the General Partner acting in good faith on the
basis of such quotations and other information as it considers, in its
reasonable judgment, appropriate.

         "AGREEMENT" shall mean the Third Amended and Restated Agreement of
Limited Partnership of the Partnership, as amended from time to time.

         "CHANGE OF CONTROL" shall mean the occurrence of any of the following
events:

                  (i) an acquisition (other than directly from the Previous
General Partner) of any voting securities of the Previous General Partner (the
"VOTING SECURITIES") by any "person" (as the term "person" is used for purposes
of Section 13(d) or Section 14(d) of the Securities Exchange Act of 1934, as
amended (the "EXCHANGE ACT")) immediately after which such person has
"beneficial ownership" (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) ("BENEFICIAL OWNERSHIP") of 20% or more of the combined voting
power of the Previous General Partner's then outstanding Voting Securities;
provided, however, in determining whether a Change in Control has occurred,
Voting Securities that are acquired in a Non-Control Acquisition (as hereinafter
defined) shall not constitute an acquisition that would cause a Change in
Control. "NON-CONTROL ACQUISITION" shall mean an acquisition by (A) an employee
benefit plan (or a trust forming a part thereof) maintained by (1) the Previous
General Partner or (2) any corporation, partnership or other person of which a
majority of its voting power or its equity securities or equity interest is
owned directly or indirectly by the Previous General Partner or in which the
Previous General Partner serves as a general

                                      KK-2
<PAGE>

partner or manager (a "SUBSIDIARY"), (B) the Previous General Partner or any
Subsidiary, or (C) any person in connection with a Non-Control Transaction (as
hereinafter defined);

                  (ii) the individuals who constitute the Board of Directors of
the Previous General Partner as of January 1, 2002 (the "INCUMBENT BOARD") cease
for any reason to constitute at least two-thirds (2/3) of the Board of
Directors; provided, however, that if the election, or nomination for election
by the Previous General Partner's stockholders, of any new director was approved
by a vote of at least two-thirds (2/3) of the Incumbent Board, such new director
shall be considered as a member of the Incumbent Board; provided, further, that
no individual shall be considered a member of the Incumbent Board if such
individual initially assumed office as a result of either an actual or
threatened "election contest" (as described in Rule 14a-11 promulgated under the
Exchange Act) (an "ELECTION CONTEST") or other actual or threatened solicitation
of proxies or consents by or on behalf of a person other than the Board of
Directors (a "PROXY CONTEST") including by reason of any agreement intended to
avoid or settle any Election Contest or Proxy Contest; or

                  (iii) approval by stockholders of the Previous General Partner
of: (A) a merger, consolidation, share exchange or reorganization involving the
Previous General Partner, unless (1) the stockholders of the Previous General
Partner, immediately before such merger, consolidation, share exchange or
reorganization, own, directly or indirectly immediately following such merger,
consolidation, share exchange or reorganization, at least 80% of the combined
voting power of the outstanding voting securities of the corporation that is the
successor in such merger, consolidation, share exchange or reorganization (the
"SURVIVING COMPANY") in substantially the same proportion as their ownership of
the Voting Securities immediately before such merger, consolidation, share
exchange or reorganization, (2) the individuals who were members of the
Incumbent Board immediately prior to the execution of the agreement providing
for such merger, consolidation, share exchange or reorganization constitute at
least two-thirds (2/3) of the members of the board of directors of the Surviving
Company, and (3) no persons (other than the Previous General Partner or any
Subsidiary, any employee benefit plan (or any trust forming a part thereof)
maintained by the Previous General Partner, the Surviving Company or any
Subsidiary, or any person who, immediately prior to such merger, consolidation,
share exchange or reorganization had Beneficial Ownership of 15% or more of the
then outstanding Voting Securities has Beneficial Ownership of 15% or more of
the combined voting power of the Surviving Company's then outstanding voting
securities (a transaction described in clauses (1) through (3) is referred to
herein as a "NON-CONTROL TRANSACTION"); (B) a complete liquidation or
dissolution of the Previous General Partner; or (C) an agreement for the sale or
other disposition of all or substantially all of the assets of the Previous
General Partner to any person (other than a transfer to a Subsidiary).

                                      KK-3
<PAGE>

         Notwithstanding the foregoing, a Change of Control shall not be deemed
to occur solely because any person (a "SUBJECT PERSON") acquired Beneficial
Ownership of more than the permitted amount of the outstanding Voting Securities
as a result of the acquisition of Voting Securities by the Previous General
Partner that, by reducing the number of Voting Securities outstanding, increases
the proportional number of shares Beneficially Owned by such Subject Person,
provided that if a Change of Control would occur (but for the operation of this
sentence) as a result of the acquisition of Voting Securities by the Previous
General Partner, and after such share acquisition by the Previous General
Partner, such Subject Person becomes the Beneficial Owner of any additional
Voting Securities that increases the percentage of the then outstanding Voting
Securities Beneficially Owned by such Subject Person, then a Change of Control
shall occur.

         "CLASS V HIGH PERFORMANCE CASH AMOUNT" shall mean, as of any date, the
lesser of (i) an amount of cash equal to the product of the amount that a Holder
would receive in respect of each Class V High Performance Partnership Unit if
the Partnership sold all of its properties at their fair market value (which may
be determined by reference to the Value of a REIT Share), paid all of its debts
and distributed the remaining proceeds to the Partners as provided in Section
13.2 of the Agreement, determined as of the applicable Valuation Date, or (ii)
in the case of a Declination followed by a Public Offering Funding, the Public
Offering Funding Amount.

         "CLASS V HIGH PERFORMANCE PARTNERSHIP UNIT" shall mean a Partnership

occurs.

         "DETERMINATION DATE" shall mean (i) when used with respect to any
dividend or other distribution, the date fixed for the determination of the
holders of the securities entitled to receive such dividend or distribution, or,
if a dividend or distribution is paid or made without fixing such a date, the
date of such dividend or distribution, and (ii) when used with respect to any
split, subdivision, reverse stock split, combination or reclassification of
securities, the date upon which such split, subdivision, reverse stock split,
combination or reclassification becomes effective.

         "DILUTION LIMIT" shall mean an amount equal to 1.0% of the total number
of REIT Shares and Partnership Common Units outstanding on the Class V High
Performance Valuation Date, on a fully diluted basis (excluding any Partnership
Common Units held by the Previous General Partner or any of its wholly owned
subsidiaries).

                                      KK-4
<PAGE>

         "EX-DATE" shall mean (i) when used with respect to any dividend or
distribution, the first date on which the securities on which the dividend or
distribution is payable trade regular way on the relevant exchange or in the
relevant market without the right to receive such dividend or distribution, and
(ii) when used with respect to any split, subdivision, reverse stock split,
combination or reclassification of securities, the first date on which the
securities trade regular way on such exchange or in such market to reflect such
split, subdivision, reverse stock split, combination or reclassification
becoming effective.

         "EXTRAORDINARY DISTRIBUTION" shall mean the distribution by the
Previous General Partner, by dividend or otherwise, to all holders of its REIT
Shares of evidences of its indebtedness or assets (including securities) other
than cash.

         "HURDLE RATE OF RETURN" shall mean the greater of (i) 36.8% (or if the
Measurement Period is less than three years, a percentage equal to the return
over the Measurement Period that would result in a cumulative return of 36.8%
over a three year period with annual compounding) or (ii) 115% of the Industry
Total Return.

         "INDUSTRY TOTAL RETURN" shall mean the Total Return of the securities
included in the Industry Peer Group Index for the Measurement Period, with such
average determined in a manner consistent with the manner in which such index is
calculated; provided, however, that if such Total Return would be less than zero
without giving effect to the reinvestment of dividends, then the "Industry Total
Return" shall be equal to zero.

         "INDUSTRY PEER GROUP INDEX" shall mean the Morgan Stanley Dean Witter
REIT Index or any other similar industry index approved by the Board of
Directors of the Previous General Partner.

         "MEASUREMENT PERIOD" shall mean the period from and including January

<PAGE>

(assuming that all dividends other than Extraordinary Distributions are
reinvested in such security as of the payment date for such dividend based on
the security price on the dividend payment date), and (B) an amount equal to (1)
the security price at the end of such period, minus (2) the security price at
the beginning of such period, divided by (ii) the security price at the
beginning of the measurement period; provided, however, that if the foregoing
calculation results in a negative number, the "Total Return" shall be equal to
zero.

         "VALUE" shall have the meaning set forth in the Agreement, except that
Value shall be determined by reference to the average of the daily market prices
for twenty (20) consecutive trading days rather than ten (10) consecutive
trading days.

         3. ADJUSTMENT OF UNITS AT CLASS V HIGH PERFORMANCE VALUATION DATE.

            On the Class V High Performance Valuation Date, without any action
on the part of the Partnership, the General Partner or the Holder of any Class V
High Performance Partnership Unit, each Class V High Performance Partnership
Unit shall automatically be adjusted to equal (a) if the Outperformance Return
is 0%, 1/100 of a Class V High Performance Partnership Unit, or (b) if the
Outperformance Return is greater than 0%, the lesser of (i) the Dilution Limit
divided by 5,000, or (ii) the quotient obtained by dividing (x) the product of
(A) 5% of the Outperformance Return, multiplied by (B) the AIMCO Equity
Capitalization, by (y) the product of (A) 5,000 and (B) the Value of a REIT
Share on the Class V High Performance Valuation Date. For illustrative purposes,
examples of the calculation of adjustments to the number Class V High
Performance Partnership Units are set forth in Annex I hereto.

         4. DISTRIBUTIONS.

            (a) Prior to the Class V High Performance Valuation Date, Holders of
Class V High Performance Partnership Units shall be entitled to receive
distributions (other than distributions upon liquidation) if, as, when and in
the same amounts and of the same type as may be paid to Holders of Partnership
Common Units as if each Holder of Class V High Performance Partnership Units
held 1/100 of a Partnership Common Unit.

            (b) On and after the Class V High Performance Valuation Date, the
Holders of Class V High Performance Partnership Units shall be entitled to
receive distributions (other than distributions upon liquidation) if, as, when
and in the same amounts and of the same type as may be paid to Holders of
Partnership Common Units as if each Holder of Class V High Performance
Partnership Units held an equal number of Partnership Common Units originally
issued on the Class V High Performance Valuation Date.

                                      KK-6

         5. ALLOCATIONS.

         (a) Prior to the Class V High Performance Valuation Date, Net Income
and Net Loss shall be allocated to the Holders of Class V High Performance
Partnership Units as if each such Holder was the Holder of 1/100 of a
Partnership Common Unit.

         (b) On and after the Class V High Performance Valuation Date, Net
Income and Net Loss shall be allocated to each of the Holders of Class V High
Performance Partnership Units as if each such Holder was the Holder of an equal
number of Partnership Common Units originally issued on the Class V High
Performance Valuation Date; provided, however, that if the Outperformance Return
is 0% on the Class V High Performance Valuation Date, then as of the last day of
the Measurement Period, each of the Holders of Class V High Performance
Partnership Units shall be specially allocated Net Loss or deduction in an
amount equal to (i) the excess of (x) the aggregate Class V High Performance
Partnership Unit capital contributions over (y) the fair market value of the
Class V High Performance Partnership Units as of such date, after applying the
adjustments required by Section 3 of this Partnership Unit Designation, divided
by (ii) the number of Class V High Performance Partnership Units held by such
Holder.

         (c) In the event that the Partnership disposes of all or substantially
all of its assets in a transaction that will lead to a liquidation of the
Partnership pursuant to Article XIII of the Agreement, then, notwithstanding
Section 6.3.C of the Agreement, each Holder of Class V High Performance
Partnership Units shall be specifically allocated items of Partnership income
and gain in an amount sufficient to cause the Capital Account of such Holder to
be equal to that of a Holder of an equal number of Partnership Common Units.

         6. REDEMPTION.

         Upon the occurrence of a Change of Control, and subject to the
applicable requirements of Federal securities laws and any securities exchange
of quotation system rules or regulations, each Holder of Class V High
Performance Partnership Units shall have the redemption rights of Qualifying
Parties set forth in Section 8.6 of the Agreement, except that (i) all
references therein to "Redeemable Units" or "Partnership Common Units" shall be
deemed to be references to Class V High Performance Partnership Units, (ii) the
first Twelve-Month Period applicable to all Class V High Performance Partnership
Units shall be deemed to have passed, (iii) all references therein to "Cash
Amount" shall be deemed to be references to the Class V High Performance Cash
Amount, and (iv) in the event that the Previous General Partner elects to
acquire Class V High Performance Partnership Units that have been tendered for
Redemption, the Previous General Partner shall acquire each such Class V High
Performance Partnership Unit in exchange for a number of REIT Shares equal to
the quotient obtained

                                      KK-7
<PAGE>

by dividing the Class V High Performance Cash Amount by the Value of a REIT
Share, determined as of the applicable Valuation Date.

         7. STATUS OF REACQUIRED UNITS.

         All Class V High Performance Partnership Units which shall have been
issued and reacquired in any manner by the Partnership shall be deemed cancelled
and no longer outstanding.

         8. RESTRICTIONS ON OWNERSHIP AND TRANSFER.

         The restrictions on Transfer set forth in Sections 11.1.B and 11.3.A of
the Agreement shall not apply to Transfers of Class V High Performance
Partnership Units. Prior to the Class V High Performance Valuation Date, the
Class V High Performance Partnership Units shall be owned and held solely by SMP
2005, L.L.C., a Delaware limited liability company (the "SMP"). On or after the
Class V High Performance Valuation Date, the Class V High Performance
Partnership Units may be Transferred (i) by the SMP to (a) any Person who is a
member (a "MEMBER") of the SMP immediately prior to such transfer, (b) a Family
Member of a Member, (c) a Controlled Entity of a Member, (c) any Person with
respect to whom the Member constitutes a Controlled Entity, (d) upon the death
of a Member, by will or by the laws of descent and distribution to any Qualified
Transferee, and (ii) by any other Person to (a) a Family Member of a such
Person, (b) a Controlled Entity of such Person, (c) any other Person with
respect to whom such Person constitutes a Controlled Entity, (d) upon the death
of such Person, by will or by the laws of descent and distribution to any
Qualified Transferee.

         9. VOTING RIGHTS.

         Each Holder of Class V High Performance Partnership Units shall have
the same voting and approval rights as a Holder of an equal number of
Partnership Common Units.

         10. ADJUSTMENTS.

             (a) In the event of any Extraordinary Distribution occurring on or
after January 1, 2002, for purposes of determining the Value of a REIT Share or
the AIMCO Total Return, each price of a REIT Share determined as of a date on or
after the Ex-Date for such Extraordinary Distribution shall be adjusted by
multiplying such price by a fraction (i) the numerator of which shall be the
price of a REIT Share on the date immediately prior to such Ex-Date, and (ii)
the denominator of which shall be (A) the price of a REIT Share on the date
immediately prior to such Ex-Date, minus (B) the fair market value on the date
fixed for such determination of the portion of the evidences of indebtedness or
assets so distributed applicable to one REIT Share (as determined by the General
Partner, whose determination shall be conclusive); provided further, that such

                                      KK-8
<PAGE>

amount shall be so adjusted for each such Extraordinary Distribution occurring
on or after January 1, 2002.

             (b) In the event that, on or after January 1, 2002, the Previous
General Partner (i) declares or pays a dividend on its outstanding REIT Shares
in REIT Shares or makes a distribution to all holders of its outstanding REIT
Shares in REIT Shares, (ii) splits or subdivides its outstanding REIT Shares,
(iii) effects a reverse stock split or otherwise combines its outstanding REIT
Shares into a smaller number of REIT Shares, or (iv) otherwise reclassifies its
outstanding REIT Shares, then, for purposes of determining the Value of a REIT
Share or the AIMCO Total Return, each price of a REIT Share determined as of a
date on or after the Ex-Date for such transaction shall be adjusted by
multiplying such price by a fraction (x) the numerator of which shall be the
number of REIT Shares issued and outstanding on the Determination Date for such
dividend, distribution, split, subdivision, reverse stock split, combination or
reclassification (assuming for such purposes that such dividend, distribution,
split, subdivision, reverse split or combination has occurred as of such time)
and (y) the denominator of which shall be the actual number of REIT Shares
(determined without the above assumption) issued and outstanding on the
Determination Date for such dividend, distribution, split, subdivision, reverse
stock split, combination or reclassification.

             (c) The General Partner shall have authority to appropriately
adjust the AIMCO Market Value, the AIMCO Total Return or the Value of a REIT
Share if any other transaction or circumstance occurs or arises that would have
an inequitable result.

         11. GENERAL.

         Class V High Performance Partnership Units shall be evidenced by
certificates in the form of Annex II hereto, or in such other form as the
General Partner shall specify from time to time. The Class V High Performance
Partnership Units shall be securities governed by Article 8 of the Uniform
Commercial Code. Each certificate evidencing a Class V High Performance
Partnership Unit shall bear the following legend: "This certificate evidences an
interest in AIMCO Properties, L.P. and shall be a security for purposes of the
Uniform Commercial Code." This provision shall not be amended, and any purported
amendment to this provision shall not take effect until all outstanding
certificates have been surrendered for cancellation. The General Partner shall
amend Exhibit A to the Agreement from time to time to the extent necessary to
reflect accurately the issuance of, and subsequent conversion, redemption, or
any other event having an effect on the ownership of, Class V High Performance
Partnership Units.

   Class V High Performance Partnership Units on the Class V High Performance
                                 Valuation Date

         The following table illustrates the adjustment that would be made to
the number of Class V High Performance Partnership Units on the Class V High
Performance Valuation Date under different circumstances. Except as otherwise
indicated, it is assumed, for purposes of the illustration, that: (i) the Class
V High Performance Valuation Date is January 1, 2005; (ii) the Industry Total
Return is 36.8%, resulting in a Hurdle Rate of Return of 42.3%; and (iii) the
AIMCO market capitalization is $3.965 billion.
