                                  THE CREDITS

         2.1      Commitment. From and including the date of this Agreement and
prior to the Facility Termination Date, subject to the terms and conditions set
forth in this Agreement, (a) each Lender severally agrees to make Loans to the
Borrower from time to time in amounts not to exceed in the aggregate at any one
time outstanding the amount of its Commitment and (b) the Issuer agrees to issue
Letters of Credit for the account of the Borrower in an aggregate amount not to
exceed $10,000,000 (and each Lender severally agrees to participate in each such
Letter of Credit as more fully set forth in Section 2.20). Subject to the terms
of this Agreement, the Borrower may borrow, repay and reborrow at any time prior
to the Facility Termination Date. The Commitments hereunder shall expire on the
Facility Termination Date. Any repayments of Loans after the Facility
Termination Date may not be reborrowed.

         2.2      Required Payments; Maturity. The Aggregate Outstanding Credit
Exposure and all other unpaid Obligations shall be paid in full (or, the case of
any Letter of Credit, a Letter of Credit Collateral Account shall be established
in accordance with Section 2.20(xi)) by the Borrower on the Final Maturity Date.

         2.3      Ratable Loans. Each Advance hereunder shall consist of Loans
made from the several Lenders ratably in proportion to the ratio that their
respective Commitments bear to the Aggregate Commitment.

         2.4      Types of Advances. The Advances may be Floating Rate Advances
or Eurodollar Advances, or a combination thereof, selected by the Borrower in
accordance with Sections 2.8 and 2.9.

         2.5      Commitment Fee; Changes in Aggregate Commitment; Up-Front
Fees.

         (i)      The Borrower agrees to pay to the Agent for the account of
each Lender a commitment fee at a per annum rate equal to the Commitment Fee
Rate on the daily unused portion of such Lender's Commitment from the date
hereof to and including the Facility Termination Date, payable on each Payment
Date hereafter and on the Facility Termination Date.

                                       12


         (ii)     The Borrower may permanently reduce the Aggregate Commitment
in whole, or in part ratably among the Lenders in integral multiples of
$1,000,000, upon at least ten (10) Business Days' written notice to the Agent,
which notice shall specify the amount of any such reduction, provided that the
amount of the Aggregate Commitment may not be reduced below the Aggregate
Outstanding Credit Exposure. All accrued commitment fees shall be payable on the
effective date of any termination of the obligations of the Lenders to make
Loans hereunder.

         (iii)    The Borrower may, from time to time, by means of a letter
delivered to the Agent substantially in the form of Exhibit E, request that the
Aggregate Commitment be increased to up to $125,000,000 (less the amount of any
previous reductions of the Aggregate Commitment pursuant to clause (ii) above)
by (a) increasing the Commitment of one or more Lenders which have agreed to
such increase and/or (b) adding one or more commercial banks or other Persons as
a party hereto (each an "Additional Lender") with a Commitment in an amount
agreed to by any such Additional Lender; provided that no Additional Lender
shall be added as a party hereto without the written consent of the Agent (which
shall not be unreasonably withheld) or if a Default or an Unmatured Default
exists. Any increase in the Aggregate Commitment pursuant to this clause (iii)
shall be effective three Business Days after the date on which the Agent has
received (and, to the extent applicable, consented to) the applicable increase
letter in the form of Annex 1 to Exhibit E (in the case of an increase in the
Commitment of an existing Lender) or assumption letter in the form of Annex 2 to
Exhibit E (in the case of an Additional Lender). The Agent shall promptly notify
the Borrower and the Lenders of any increase in the amount of the Aggregate
Commitment pursuant to this clause (iii) and of each Lender's pro rata share of
the Aggregate Commitment of each Lender after giving effect thereto. The
Borrower acknowledges that, in order to maintain ratable Advances in accordance
with each Lender's pro rata share of the Aggregate Commitment, prepayment of all
or portions of certain ratable Advances may be required on the date of any
increase in the Aggregate Commitment pursuant to this clause (iii) (and any such
prepayment shall be subject to the provisions of Section 3.4).

         (iv)     The Borrower agrees to pay to the Agent on behalf of each
Lender on the date the Borrower signs this Agreement an up-front fee in the
amount previously agreed upon among the Company, the Agent and such Lender.

         2.6      Minimum Amount of Each Advance. Each Eurodollar Advance shall
be in the minimum amount of $1,000,000 (and in multiples of $100,000 if in
excess thereof), and each Floating Rate Advance shall be in the minimum amount
of $1,000,000 (and in multiples of $100,000 if in excess thereof), provided that
any Floating Rate Advance may be in the amount of the unused Aggregate
Commitment.

         2.7      Optional Principal Payments. The Borrower may from time to
time pay, without penalty or premium, all outstanding Floating Rate Advances,
or, in a minimum aggregate amount of $1,000,000 or any integral multiple of
$100,000 in excess thereof, any portion of the outstanding Floating Rate
Advances upon two Business Days' prior notice to the Agent. The Borrower may
from time to time pay, subject to the payment of any funding indemnification
amounts required by Section 3.4 but without penalty or premium, all outstanding
Eurodollar Advances, or, in a minimum aggregate amount of $1,000,000 or any
integral multiple of $100,000 in excess thereof, any portion of the outstanding
Eurodollar Advances upon three Business Days' prior notice to the Agent.

                                       13


         2.8      Method of Selecting Types and Interest Periods for New
Advances. The Borrower shall select the Type of Advance and, in the case of each
Eurodollar Advance, the Interest Period applicable thereto from time to time.
The Borrower shall give the Agent irrevocable notice (a "Borrowing Notice") not
later than 10:00 a.m. (Chicago time) at least one Business Day before the
Borrowing Date of each Floating Rate Advance and three Business Days before the
Borrowing Date for each Eurodollar Advance, specifying:

         (i)      the Borrowing Date, which shall be a Business Day, of such
                  Advance,

         (ii)     the aggregate amount of such Advance,

         (iii)    the Type of Advance selected, and

         (iv)     in the case of each Eurodollar Advance, the Interest Period
                  applicable thereto.

Not later than noon (Chicago time) on each Borrowing Date, each Lender shall
make available its Loan or Loans in funds immediately available in Chicago to
the Agent at its address specified pursuant to Article XIII. The Agent will make
the funds so received from the Lenders available to the Borrower at the Agent's
aforesaid address.

         2.9      Conversion and Continuation of Outstanding Advances. Floating
Rate Advances shall continue as Floating Rate Advances unless and until such
Floating Rate Advances are converted into Eurodollar Advances pursuant to this
Section 2.9 or are repaid in accordance with Section 2.7. Each Eurodollar
Advance shall continue as a Eurodollar Advance until the end of the then
applicable Interest Period therefor, at which time such Eurodollar Advance shall
be automatically converted into a Floating Rate Advance unless (x) such
Eurodollar Advance is or was repaid in accordance with Section 2.7 or (y) the
Borrower shall have given the Agent a Conversion/Continuation Notice (as defined
below) requesting that, at the end of such Interest Period, such Eurodollar
Advance continue as a Eurodollar Advance for the same or another Interest
Period. Subject to the terms of Section 2.6, the Borrower may elect from time to
time to convert all or any part of a Floating Rate Advance into a Eurodollar
Advance. The Borrower shall give the Agent irrevocable notice (a
"Conversion/Continuation Notice") of each conversion of a Floating Rate Advance
into a Eurodollar Advance or continuation of a Eurodollar Advance not later than
10:00 a.m. (Chicago time) at least three Business Days prior to the date of the
requested conversion or continuation, specifying:

         (i)      the requested date, which shall be a Business Day, of such
                  conversion or continuation,

         (ii)     the aggregate amount and Type of the Advance which is to be
                  converted or continued, and

         (iii)    the amount of such Advance which is to be converted into or
                  continued as a Eurodollar Advance and the duration of the
                  Interest Period applicable thereto.

         2.10     Changes in Interest Rate, etc. Each Floating Rate Advance
shall bear interest on the outstanding principal amount thereof, for each day
from and including the date such Advance is made or is automatically converted
from a Eurodollar Advance into a Floating Rate Advance

                                       14


pursuant to Section 2.9, to but excluding the date it is paid or is converted
into a Eurodollar Advance pursuant to Section 2.9 hereof, at a rate per annum
equal to the Floating Rate for such day. Changes in the rate of interest on that
portion of any Advance maintained as a Floating Rate Advance will take effect
simultaneously with each change in the Alternate Base Rate. Each Eurodollar
Advance shall bear interest on the outstanding principal amount thereof from and
including the first day of the Interest Period applicable thereto to (but not
including) the last day of such Interest Period at the interest rate determined
by the Agent as applicable to such Eurodollar Advance based upon the Borrower's
selections under Sections 2.8 and 2.9 and otherwise in accordance with the terms
hereof. No Interest Period may end after the Final Maturity Date.

         2.11     Rates Applicable After Default. Notwithstanding anything to
the contrary contained in Section 2.8 or 2.9, during the continuance of a
Default or Unmatured Default the Required Lenders may, at their option, by
notice to the Borrower (which notice may be revoked at the option of the
Required Lenders notwithstanding any provision of Section 8.2 requiring
unanimous consent of the Lenders to changes in interest rates), declare that no
Advance may be made as, converted into or continued as a Eurodollar Advance.
During the continuance of a Default the Required Lenders may, at their option,
by notice to the Borrower (which notice may be revoked at the option of the
Required Lenders notwithstanding any provision of Section 8.2 requiring
unanimous consent of the Lenders to changes in interest rates), declare that (i)
each Eurodollar Advance shall bear interest for the remainder of the applicable
Interest Period at the rate otherwise applicable to such Interest Period plus 2%
per annum, (ii) each Floating Rate Advance shall bear interest at a rate per
annum equal to the Floating Rate in effect from time to time plus 2% per annum
and (iii) the Letter of Credit Fee Rate shall be increased by 2% per annum,
provided that, during the continuance of a Default under Section 7.6 or 7.7, the
interest rates set forth in clauses (i) and (ii) above and the increase in the
Letter of Credit Fee Rate set forth in clause (iii) above shall be applicable to
all applicable Credit Extensions without any election or action on the part of
the Agent or any Lender.

         2.12     Method of Payment. All payments of the Obligations hereunder
shall be made, without setoff, deduction, or counterclaim, in immediately
available funds to the Agent at the Agent's address specified pursuant to
Article XIII, or at any other Lending Installation of the Agent specified in
writing by the Agent to the Borrower, by noon (local time) on the date when due
and shall be applied ratably by the Agent among the Lenders. Each payment
delivered to the Agent for the account of any Lender shall be delivered promptly
by the Agent to such Lender in the same type of funds that the Agent received at
its address specified pursuant to Article XIII or at any Lending Installation
specified in a notice received by the Agent from such Lender. The Agent is
hereby authorized to charge the account of the Borrower maintained with Bank One
for each payment of principal, interest, Reimbursement Obligations and fees as
it becomes due hereunder.

         2.13     Noteless Agreement; Evidence of Indebtedness. (i) Each Lender
shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower to such Lender resulting from each
Loan made by such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

                                       15


         (ii) The Agent shall also maintain accounts in which it will record (a)
the amount of each Loan made hereunder, the Type thereof and the Interest Period
with respect thereto, (b) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder,
(c) the original stated amount of each Letter of Credit and the amount of Letter
of Credit Obligations outstanding at any time and (d) the amount of any sum
received by the Agent hereunder from the Borrower and each Lender's share
thereof.

         (iii) The entries maintained in the accounts maintained pursuant to
paragraphs (i) and (ii) above shall be prima facie evidence of the existence and
amounts of the Obligations therein recorded; provided that the failure of the
Agent or any Lender to maintain such accounts or any error therein shall not in
any manner affect the obligation of the Borrower to repay the Obligations in
accordance with their terms.

         (iv) Any Lender may request that its Loans be evidenced by a Note. In
such event, the Borrower shall prepare, execute and deliver to such Lender a
Note payable to the order of such Lender. Thereafter, the Loans evidenced by
such Note and interest thereon shall at all times (including after any
assignment pursuant to Section 12.3) be represented by one or more Notes payable
to the order of the payee named therein or any assignee pursuant to Section
12.3, except to the extent that any such Lender or assignee subsequently returns
any such Note for cancellation and requests that such Loans once again be
evidenced as described in paragraphs (i) and (ii) above.

         2.14     Telephonic Notices. The Borrower hereby authorizes the Lenders
and the Agent to extend, convert or continue Advances, effect selections of
Types of Advances and to transfer funds based on telephonic notices made by any
person or persons the Agent or any Lender in good faith believes to be acting on
behalf of the Borrower, it being understood that the foregoing authorization is
specifically intended to allow Borrowing Notices and Conversion/Continuation
Notices to be given telephonically. The Borrower agrees to deliver promptly to
the Agent a written confirmation, if such confirmation is requested by the Agent
or any Lender, of each telephonic notice signed by an Authorized Officer. If the
written confirmation differs in any material respect from the action taken by
the Agent and the Lenders, the records of the Agent and the Lenders shall govern
absent manifest error.

         2.15     Interest Payment Dates; Interest and Fee Basis. Interest
accrued on each Floating Rate Advance shall be payable on each Payment Date,
commencing with the first such date to occur after the date hereof, on any date
on which the Floating Rate Advance is prepaid, whether due to acceleration or
otherwise, and at maturity. Interest accrued on that portion of the outstanding
principal amount of any Floating Rate Advance converted into a Eurodollar
Advance on a day other than a Payment Date shall be payable on the date of
conversion. Interest accrued on each Eurodollar Advance shall be payable on the
last day of its applicable Interest Period, on any date on which the Eurodollar
Advance is prepaid, whether by acceleration or otherwise, and at maturity.
Interest accrued on each Eurodollar Advance having an Interest Period longer
than three months shall also be payable on the last day of each three-month
interval during such Interest Period. Interest and commitment fees shall be
calculated for actual days elapsed on the basis of a 360-day year, except that
interest accruing at the Prime Rate shall be calculated for actual days elapsed
on the basis of a 365, or when appropriate 366, day year. Interest shall be
payable for the day an Advance is made but not for the day of any payment on the
amount paid if

                                       16


payment is received prior to noon (local time) at the place of payment. If any
payment of principal of or interest on an Advance shall become due on a day
which is not a Business Day, such payment shall be made on the next succeeding
Business Day and, in the case of a principal payment, such extension of time
shall be included in computing interest in connection with such payment.

         2.16     Notification of Advances, Interest Rates, Prepayments and
Commitment Reductions. Promptly after receipt thereof, the Agent will notify
each Lender of the contents of each Aggregate Commitment reduction notice,
Borrowing Notice, Conversion/Continuation Notice, and repayment notice received
by it hereunder. The Agent will notify each Lender of the interest rate
applicable to each Eurodollar Advance promptly upon determination of such
interest rate and will give each Lender prompt notice of each change in the
Alternate Base Rate.

         2.17     Lending Installations. Each Lender may book its Loans at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any
such Lending Installation and the Loans and any Notes issued hereunder shall be
deemed held by each Lender for the benefit of any such Lending Installation.
Each Lender may, by written notice to the Agent and the Borrower in accordance
with Article XIII, designate replacement or additional Lending Installations
through which Loans will be made by it and for whose account Loan payments are
to be made.

         2.18     Non-Receipt of Funds by the Agent. Unless the Borrower or a
Lender, as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made. The Agent may, but shall not be obligated to, make the amount of such
payment available to the intended recipient in reliance upon such assumption. If
such Lender or the Borrower, as the case may be, has not in fact made such
payment to the Agent, the recipient of such payment shall, on demand by the
Agent, repay to the 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 Agent until the date the Agent recovers such
amount at a rate per annum equal to (x) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day for the first three days and,
thereafter, the interest rate applicable to the relevant Loan or (y) in the case
of payment by the Borrower, the interest rate applicable to the relevant Loan.

         2.19     Replacement of Lender. If the Borrower is required pursuant to
Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any
Lender's obligation to make or continue, or to convert Floating Rate Advances
into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender
so affected an "Affected Lender"), the Borrower may elect, if such amounts
continue to be charged or such suspension is still effective, to replace such
Affected Lender as a Lender party to this Agreement, provided that no Default or
Unmatured Default shall have occurred and be continuing at the time of such
replacement, and provided, further, that, concurrently with such replacement,
(i) another bank or other entity which is reasonably satisfactory to the
Borrower and the Agent shall agree, as of such date, to purchase for cash the
Advances and other Obligations due to the Affected Lender pursuant to an
assignment substantially in the form of Exhibit B and to become a Lender for all
purposes under

                                       17


this Agreement and to assume all obligations of the Affected Lender to be
terminated as of such date and to comply with the requirements of Section 12.3
applicable to assignments, and (ii) the Borrower shall pay to such Affected
Lender in same day funds on the day of such replacement (A) all interest, fees
and other amounts then accrued but unpaid to such Affected Lender by the
Borrower hereunder to and including the date of termination, including without
limitation payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5,
and (B) an amount, if any, equal to the payment which would have been due to
such Lender on the day of such replacement under Section 3.4 had the Loans of
such Affected Lender been prepaid on such date rather than sold to the
replacement Lender.

         2.20     Letters of Credit.

         (i)      Issuance. The Issuer hereby agrees, on the terms and
conditions set forth in this Agreement, to issue standby letters of credit and
to renew, extend, increase, decrease or otherwise modify Letters of Credit
("Modify," and each such action a "Modification") from time to time from and
including the date of this Agreement and prior to the Facility Termination Date
upon the request of the Borrower; provided that immediately after each such
Letter of Credit is issued or Modified, (i) the aggregate amount of the
outstanding LC Obligations shall not exceed $10,000,000 and (ii) the Aggregate
Outstanding Credit Exposure shall not exceed the Aggregate Commitment. No Letter
of Credit shall have an expiry date later than the scheduled Facility
Termination Date. By their execution of this Agreement, the Borrower, each
Lender, the Issuer and the Agent agree that, effective as of the date of this
Agreement, the Existing LC shall be a Letter of Credit under this Agreement and
subject to the terms hereof.

         (ii)     Participations. On the date of this Agreement, with respect to
the Existing LC, and upon the issuance of each other Letter of Credit or the
Modification of any Letter of Credit in accordance with this Section 2.20, the
Issuer shall be deemed, without further action by any party hereto, to have
unconditionally and irrevocably sold to each Lender, and each Lender shall be
deemed, without further action by any party hereto, to have unconditionally and
irrevocably purchased from the Issuer, a participation in such Letter of Credit
(and each Modification thereof) and the related LC Obligations in proportion to
its pro rata share of the Aggregate Commitment.

         (iii)    Notice. Subject to Section 2.20(i), the Borrower shall give
the Issuer notice prior to 10:00 a.m. (Chicago time) at least three Business
Days prior to the proposed date of issuance or Modification of each Letter of
Credit, specifying the beneficiary, the proposed date of issuance (or
Modification) and the expiry date of such Letter of Credit, and describing the
proposed terms of such Letter of Credit and the nature of the transactions
proposed to be supported thereby. Upon receipt of such notice, the Issuer shall
promptly notify the Agent, and the Agent shall promptly notify each Lender, of
the contents thereof and of the amount of such Lender's participation in such
proposed Letter of Credit. The issuance or Modification by the Issuer of any
Letter of Credit shall, in addition to the conditions precedent set forth in
Article IV (the satisfaction of which the Issuer shall have no duty to
ascertain), be subject to the conditions precedent that such Letter of Credit
shall be satisfactory to the Issuer and that the Borrower shall have executed
and delivered such application agreement and/or such other instruments and
agreements relating to such Letter of Credit as the Issuer shall have reasonably
requested (each a

                                       18


"Letter of Credit Application"). In the event of any conflict between the terms
of this Agreement and the terms of any Letter of Credit Application, the terms
of this Agreement shall control.

         (iv)     Letter of Credit Fees. The Borrower shall pay to the Agent,
for the account of the Lenders ratably in accordance with their respective pro
rata shares of the Aggregate Commitment, with respect to each Letter of Credit,
a letter of credit fee (the "Letter of Credit Fee") at a per annum rate equal to
the Letter of Credit Fee Rate in effect from time to time on the undrawn stated
amount available under such Letter of Credit, such fee to be payable in arrears
on each Payment Date. The Borrower shall also pay to the Issuer for its own
account (x) a fronting fee in the amount agreed to by the Issuer and the
Borrower from time to time, with such fee to be payable in arrears on each
Payment Date, and (y) documentary and processing charges in connection with the
issuance or Modification of and draws under Letters of Credit in accordance with
the Issuer's standard schedule for such charges as in effect from time to time.

         (v)      Administration; Reimbursement by Lenders. Upon receipt from
the beneficiary of any Letter of Credit of any demand for payment under such
Letter of Credit, the Issuer shall notify the Agent and the Agent shall promptly
notify the Borrower and each other Lender as to the amount to be paid by the
Issuer as a result of such demand and the proposed payment date (the "Letter of
Credit Payment Date"). The responsibility of the Issuer to the Borrower and each
Lender shall be only to determine that the documents (including each demand for
payment) delivered under each Letter of Credit in connection with such
presentment shall be in conformity in all material respects with such Letter of
Credit. The Issuer shall endeavor to exercise the same care in its issuance and
administration of Letters of Credit as it does with respect to letters of credit
in which no participations are granted, it being understood that in the absence
of any gross negligence or willful misconduct by the Issuer, each Lender shall
be unconditionally and irrevocably obligated, without regard to the occurrence
of any Default or any condition precedent whatsoever, to reimburse the Issuer on
demand for (i) such Lender's pro rata share (determined by such Lender's pro
rata share of the Aggregate Commitment) of the amount of each payment made by
the Issuer under each applicable Letter of Credit to the extent such amount is
not reimbursed by the Borrower pursuant to Section 2.20(vi) below, plus (ii)
interest on the foregoing amount for each day from the date of the applicable
payment by the Issuer to the date on which such Lender pays the amount to be
reimbursed by it, at a rate of interest per annum equal to the Federal Funds
Effective Rate or, beginning on third Business Day after demand for such amount
by the Issuer, the rate applicable to Floating Rate Advances.

         (vi)     Reimbursement by Borrower. The Borrower shall be irrevocably
and unconditionally obligated to reimburse the Issuer on or before the
applicable Letter of Credit Payment Date for any amount to be paid by the Issuer
upon any drawing under any Letter of Credit issued by the Issuer, without
presentment, demand, protest or other formalities of any kind; provided that the
Borrower shall not hereby be precluded from asserting any claim for direct (but
not consequential) damages suffered by the Borrower to the extent, but only to
the extent, caused by (i) the willful misconduct or gross negligence of the
Issuer in determining whether a request presented under any Letter of Credit
issued by it complied with the terms of such Letter of Credit or (ii) the
Issuer's failure to pay under any Letter of Credit issued by it after the
presentation to it of a request strictly complying with the terms and conditions
of such Letter of Credit. All such amounts paid by the Issuer and remaining
unpaid by the Borrower shall bear interest, payable on demand, for each day
until paid at a rate per annum equal to the sum of 2%

                                       19


plus the rate applicable to Floating Rate Advances. The Issuer will pay to each
Lender ratably in accordance with its pro rata share of the Aggregate Commitment
all amounts received by it from the Borrower for application in payment, in
whole or in part, of the Reimbursement Obligation in respect of any Letter of
Credit issued by the Issuer, but only to the extent such Lender has made payment
to the Issuer in respect of such Letter of Credit pursuant to Section 2.20(v).

         (vii)    Obligations Absolute. The Borrower's obligations under this
Section 2.20 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment which the
Borrower may have or have had against the Issuer, any Lender or any beneficiary
of a Letter of Credit. The Borrower further agrees with the Issuer and the
Lenders that neither the Issuer nor any Lender shall be responsible for, and the
Borrower's Reimbursement Obligation in respect of any Letter of Credit shall not
be affected by, among other things, the validity or genuineness of documents or
of any endorsements thereon, even if such documents should in fact prove to be
in any or all respects invalid, fraudulent or forged, or any dispute between or
among the Borrower, any of its Affiliates, the beneficiary of any Letter of
Credit or any financing institution or other party to whom any Letter of Credit
may be transferred or any claims or defenses whatsoever of the Borrower or of
any of its Affiliates against the beneficiary of any Letter of Credit or any
such transferee. The Issuer shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit. The
Borrower agrees that any action taken or omitted by the Issuer or any Lender
under or in connection with any Letter of Credit and the related drafts and
documents, if done without gross negligence or willful misconduct, shall be
binding upon the Borrower and shall not put the Issuer or any Lender under any
liability to the Borrower. Nothing in this Section 2.20(vii) is intended to
limit the right of the Borrower to make a claim against the Issuer for damages
as contemplated by the proviso to the first sentence of Section 2.20(vi).

         (viii)   Actions of Issuer. The Issuer shall be entitled to rely, and
shall be fully protected in relying, upon any Letter of Credit, draft, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, facsimile, telex or teletype message, statement, order or other
document believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons, and upon advice and statements of legal
counsel, independent accountants and other experts selected by the Issuer. The
Issuer shall be fully justified in failing or refusing to take any action under
this Agreement unless it shall first have received such advice or concurrence of
the Required Lenders as it reasonably deems appropriate or it shall first be
indemnified to its reasonable satisfaction by the Lenders against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. Notwithstanding any other provision of this
Section 2.20, the Issuer shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement in accordance with a request of the
Required Lenders, and such request and any action taken or failure to act
pursuant thereto shall be binding upon the Lenders and any future holders of a
participation in any Letter of Credit.

         (ix)     Indemnification. The Borrower hereby agrees to indemnify and
hold harmless each Lender, the Issuer and the Agent, and their respective
directors, officers, agents and employees, from and against any and all claims
and damages, losses, liabilities, costs or expenses which such Lender, the
Issuer or the Agent may incur (or which may be claimed against such

                                       20


Lender, the Issuer or the Agent by any Person whatsoever) by reason of or in
connection with the issuance, execution and delivery or transfer of or payment
or failure to pay under any Letter of Credit or any actual or proposed use of
any Letter of Credit, including, without limitation, any claims, damages,
losses, liabilities, costs or expenses which the Issuer may incur by reason of
or in connection with (i) the failure of any other Lender to fulfill or comply
with its obligations to the Issuer hereunder (but nothing herein contained shall
affect any rights the Borrower may have against any defaulting Lender) or (ii)
by reason of or on account of the Issuer issuing any Letter of Credit which
specifies that the term "Beneficiary" included therein includes any successor by
operation of law of the named Beneficiary, but which Letter of Credit does not
require that any drawing by any such successor Beneficiary be accompanied by a
copy of a legal document, satisfactory to the Issuer, evidencing the appointment
of such successor Beneficiary; provided that the Borrower shall not be required
to indemnify any Lender, the Issuer or the Agent for any claims, damages,
losses, liabilities, costs or expenses to the extent, but only to the extent,
caused by (x) the willful misconduct or gross negligence of the Issuer in
determining whether a request presented under any Letter of Credit issued by the
Issuer complied with the terms of such Letter of Credit or (y) the Issuer's
failure to pay under any Letter of Credit after the presentation to it of a
request strictly complying with the terms and conditions of such Letter of
Credit. Nothing in this Section 2.20(ix) is intended to limit the obligations of
the Borrower under any other provision of this Agreement.

         (X)      Lenders' Indemnification. Each Lender shall, ratably in
accordance with its pro rata share of the Aggregate Commitment, indemnify the
Issuer, its affiliates and its directors, officers, agents and employees (to the
extent not reimbursed by the Borrower) against any cost, expense (including
reasonable counsel fees and disbursements), claim, demand, action, loss or
liability (except such as result from such indemnitees' gross negligence or
willful misconduct or the Issuer's failure to pay under any Letter of Credit
after the presentation to it of a request strictly complying with the terms and
conditions of the Letter of Credit) that such indemnitees may suffer or incur in
connection with this Section 2.20 or any action taken or omitted by such
indemnitees hereunder.

         (xi)     Letter of Credit Collateral Account. The Borrower agrees that
it will, upon the request of the Agent or the Required Lenders and until the
final expiration date of any Letter of Credit and thereafter as long as any
amount is payable to the Issuer or the Lenders in respect of any Letter of
Credit, maintain a special collateral account pursuant to arrangements
satisfactory to the Agent (the "Letter of Credit Collateral Account") at the
Agent's office at the address specified pursuant to Article XIII, in the name of
such Borrower but under the sole dominion and control of the Agent, for the
benefit of the Lenders and in which the Borrower shall have no interest other
than as set forth in Section 8.1. The Borrower hereby pledges, assigns and
grants to the Agent, on behalf of and for the ratable benefit of the Lenders and
the Issuer, a security interest in all of the Borrower's right, title and
interest in and to all funds which may from time to time be on deposit in the
Letter of Credit Collateral Account to secure the prompt and complete payment
and performance of the Obligations. The Agent will invest any funds on deposit
from time to time in the Letter of Credit Collateral Account in certificates of
deposit of Bank One having a maturity not exceeding 30 days. Nothing in this
Section 2.20(xi) shall either obligate the Agent to require the Borrower to
deposit any funds in the Letter of Credit Collateral Account or limit the right
of the Agent to release any funds held in the Letter of Credit Collateral
Account in each case other than as required by Section 8.1; provided that if one
or more Letters

                                       21


of Credit are outstanding on the Facility Termination Date, the Borrower shall
deposit funds in the Letter of Credit Collateral Account in an amount equal to
the stated amount of all such Letters of Credit, and such account shall at all
times thereafter have a balance in excess of the full amount available to be
drawn under such Letters of Credit.

         (xii)    Rights as a Lender. In its capacity as a Lender, the Issuer
shall have the same rights and obligations as any other Lender.

                                  ARTICLE III.

                             YIELD PROTECTION; TAXES

         3.1      Yield Protection. If, on or after the date of this Agreement,
the adoption of or any change in any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law), or any change in the interpretation or
administration thereof by any governmental or quasi-governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender, any applicable Lending
Installation or the Issuer with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency:

         (i)      subjects any Lender, any applicable Lending Installation or
                  the Issuer to any Taxes, or changes the basis of taxation of
                  payments (other than with respect to Excluded Taxes) to any
                  Lender or the Issuer in respect of its Eurodollar Loans,
                  Letters of Credit or participations therein, or

         (ii)     imposes or increases or deems applicable any reserve,
                  assessment, insurance charge, special deposit or similar
                  requirement against assets of, deposits with or for the
                  account of, or credit extended by, any Lender, any applicable
                  Lending Installation or the Issuer (other than reserves and
                  assessments taken into account in determining the interest
                  rate applicable to Eurodollar Advances), or

         (iii)    imposes any other condition the result of which is to increase
                  the cost to any Lender, any applicable Lending Installation or
                  the Issuer of making, funding or maintaining its Eurodollar
                  Loans or of issuing or participating in Letters of Credit or
                  reduces any amount receivable by any Lender, any applicable
                  Lending Installation or the Issuer in connection with its
                  Eurodollar Loans or Letters of Credit, or requires any Lender,
                  any applicable Lending Installation or the Issuer to make any
                  payment calculated by reference to the amount of Eurodollar
                  Loans or Letters of Credit held or interest received by it, by
                  an amount deemed material by such Lender or the Issuer, as the
                  case may be,

and the result of any of the foregoing is to increase the cost to such Lender,
the applicable Lending Installation or the Issuer of making or maintaining its
Eurodollar Loans, Letters of Credit or Commitment or to reduce the return
received by such Lender, the applicable Lending Installation or the Issuer in
connection with such Eurodollar Loans, Letters of Credit or Commitment, then,
within 15 days of demand by such Lender or the Issuer, the Borrower shall

                                       22


pay such Lender or the Issuer such additional amount or amounts as will
compensate such Lender or the Issuer for such increased cost or reduction in
amount received.

         3.2      Changes in Capital Adequacy Regulations. If a Lender or the
Issuer determines the amount of capital required or expected to be maintained by
such Lender, the Issuer, any Lending Installation of such Lender or any
corporation controlling such Lender or the Issuer is increased as a result of a
Change, then, within 15 days of demand by such Lender or the Issuer, the
Borrower shall pay such Lender or the Issuer the amount necessary to compensate
for any shortfall in the rate of return on the portion of such increased capital
which such Lender or the Issuer determines is attributable to this Agreement,
its Outstanding Credit Exposure or its Commitment to make Loans and issue or
participate in Letters of Credit, as the case may be, hereunder (after taking
into account such Lender's or the Issuer's policies as to capital adequacy).
"Change" means (i) any change after the date of this Agreement in the Risk-Based
Capital Guidelines or (ii) any adoption of or change in any other law,
governmental or quasi-governmental rule, regulation, policy, guideline,
interpretation, or directive (whether or not having the force of law) after the
date of this Agreement which affects the amount of capital required or expected
to be maintained by any Lender, any Lending Installation or the Issuer or any
corporation controlling any Lender or the Issuer. "Risk-Based Capital
Guidelines" means (i) the risk-based capital guidelines in effect in the United
States on the date of this Agreement, including transition rules, and (ii) the
corresponding capital regulations promulgated by regulatory authorities outside
the United States implementing the July 1988 report of the Basle Committee on
Banking Regulation and Supervisory Practices Entitled "International Convergence
of Capital Measurements and Capital Standards," including transition rules, and
any amendments to such regulations adopted prior to the date of this Agreement.

         3.3      Availability of Types of Advances. If any Lender determines
that maintenance of its Eurodollar Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders determine that (i) deposits
of a type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to Eurodollar Advances does not
accurately reflect the cost of making or maintaining Eurodollar Advances, then
the Agent shall suspend the availability of Eurodollar Advances and require any
affected Eurodollar Advances to be repaid or converted to Floating Rate Advances
(on or before the date required by such law, rule, regulation or directive),
subject to the payment of any funding indemnification amounts required by
Section 3.4.

         3.4      Funding Indemnification. If any payment of a Eurodollar
Advance occurs on a date which is not the last day of the applicable Interest
Period, whether because of acceleration, prepayment or otherwise, or a
Eurodollar Advance is not made on the date specified by the Borrower for any
reason other than default by the Lenders, the Borrower will indemnify each
Lender for any loss or cost incurred by it resulting therefrom, including,
without limitation, any loss or cost in liquidating or employing deposits
acquired to fund or maintain such Eurodollar Advance.

         3.5      Taxes. (i) All payments by the Borrower to or for the account
of any Lender, the Issuer or the Agent hereunder or under any Note shall be made
free and clear of and without deduction for any and all Taxes. If the Borrower
shall be required by law to deduct any Taxes

                                       23


from or in respect of any sum payable hereunder to any Lender, the Issuer or the
Agent, (a) the sum payable shall be increased as necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section 3.5) such Lender, the Issuer or the Agent (as the
case may be) receives an amount equal to the sum it would have received had no
such deductions been made, (b) the Borrower shall make such deductions, (c) the
Borrower shall pay the full amount deducted to the relevant authority in
accordance with applicable law and (d) the Borrower shall furnish to the Agent
the original copy of a receipt evidencing payment thereof within 30 days after
such payment is made.

         (ii) In addition, the Borrower hereby agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or under
any Note or Letter of Credit Application or from the execution or delivery of,
or otherwise with respect to, this Agreement, any Note or any Letter of Credit
Application ("Other Taxes").

         (iii) The Borrower hereby agrees to indemnify the Agent, each Lender
and the Issuer for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed on amounts payable under this
Section 3.5) paid by the Agent, such Lender or the Issuer and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto. Payments due under this indemnification shall be made within 30 days of
the date the Agent, such Lender or the Issuer makes demand therefor pursuant to
Section 3.6.

         (iv) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof (each a "Non-U.S. Lender") agrees that it
will, not less than ten Business Days after the date of this Agreement, (i)
deliver to each of the Borrower and the Agent two duly completed copies of
United States Internal Revenue Service Form 1001 or 4224, certifying in either
case that such Lender is entitled to receive payments under this Agreement
without deduction or withholding of any United States federal income taxes, and
(ii) deliver to each of the Borrower and the Agent a United States Internal
Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to
an exemption from United States backup withholding tax. Each Non-U.S. Lender
further undertakes to deliver to each of the Borrower and the Agent (x) renewals
or additional copies of such form (or any successor form) on or before the date
that such form expires or becomes obsolete, and (y) after the occurrence of any
event requiring a change in the most recent forms so delivered by it, such
additional forms or amendments thereto as may be reasonably requested by the
Borrower or the Agent. All forms or amendments described in the preceding
sentence shall certify that such Lender is entitled to receive payments under
this Agreement without deduction or withholding of any United States federal
income taxes, unless an event (including without limitation any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form or amendment with respect to it and such Lender advises the Borrower and
the Agent that it is not capable of receiving payments without any deduction or
withholding of United States federal income tax.

         (v) For any period during which a Non-U.S. Lender has failed to provide
the Borrower with an appropriate form pursuant to clause (iv), above (unless
such failure is due to a change in treaty, law or regulation, or any change in
the interpretation or administration thereof by any

                                       24


governmental authority, occurring subsequent to the date on which a form
originally was required to be provided), such Non-U.S. Lender shall not be
entitled to indemnification under this Section 3.5 with respect to Taxes imposed
by the United States; provided that, should a Non-U.S. Lender which is otherwise
exempt from or subject to a reduced rate of withholding tax become subject to
Taxes because of its failure to deliver a form required under clause (iv),
above, the Borrower shall take such steps as such Non-U.S. Lender shall
reasonably request to assist such Non-U.S. Lender to recover such Taxes.

         (vi) Any Lender that is entitled to an exemption from or reduction of
withholding tax with respect to payments under this Agreement or any Note
pursuant to the law of any relevant jurisdiction or any treaty shall deliver to
the Borrower (with a copy to the Agent), at the time or times prescribed by
applicable law, such properly completed and executed documentation prescribed by
applicable law as will permit such payments to be made without withholding or at
a reduced rate.

         (vii) If the U.S. Internal Revenue Service or any other governmental
authority of the United States or any other country or any political subdivision
thereof asserts a claim that the Agent did not properly withhold tax from
amounts paid to or for the account of any Lender (because the appropriate form
was not delivered or properly completed, because such Lender failed to notify
the Agent of a change in circumstances which rendered its exemption from
withholding ineffective, or for any other reason), such Lender shall indemnify
the Agent fully for all amounts paid, directly or indirectly, by the Agent as
tax, withholding therefor, or otherwise, including penalties and interest, and
including taxes imposed by any jurisdiction on amounts payable to the Agent
under this subsection, together with all costs and expenses related thereto
(including attorneys fees and time charges of attorneys for the Agent, which
attorneys may be employees of the Agent). The obligations of the Lenders under
this Section 3.5(vii) shall survive the payment of the Obligations and
termination of this Agreement.

         3.6      Lender Statements; Survival of Indemnity. To the extent
reasonably possible, each Lender shall designate an alternate Lending
Installation with respect to its Eurodollar Loans to reduce any liability of the
Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the
unavailability of Eurodollar Advances under Section 3.3, so long as such
designation is not, in the judgment of such Lender, disadvantageous to such
Lender. Each Lender shall deliver a written statement of such Lender to the
Borrower (with a copy to the Agent) as to the amount due, if any, under Section
3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable
detail the calculations upon which such Lender determined such amount and shall
be final, conclusive and binding on the Borrower in the absence of manifest
error. Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable on demand after receipt by the Borrower of such written statement. The
obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive
payment of the Obligations and termination of this Agreement.

                                       25


                                  ARTICLE IV.

                              CONDITIONS PRECEDENT

         4.1      Initial Credit Extension. The Lenders and the Issuer shall not

                  Borrower, together with all amendments, and a certificate of

                  Borrower authorized to sign the Loan Documents to which the
                  Borrower is a party, upon which certificate the Agent and the
                  Lenders shall be entitled to rely until informed of any change
                  in writing by the Borrower.

         (iv)     Evidence,in form and substance satisfactory to the Agent, that

                  Letter of Credit hereunder on the date of this Agreement).

         (x)      If the initial Credit Extension will be the issuance of a

         (xi)     Such other documents as any Lender or its counsel may have

                  extent any such representation or warranty is stated to relate
                  solely to an earlier date, in which case such representation
                  or warranty shall have been true and correct on and as of such
                  earlier date.

         (iii)    All legal matters incident to the making of such Credit

         Each Borrowing Notice and each request for the issuance of a Letter of

conditions contained in Sections 4.2(i) and (ii) have been satisfied.

                                   ARTICLE V.

                         REPRESENTATIONS AND WARRANTIES

         The Borrower represents and warrants to the Lenders that:

         5.1      Existence and Standing. Each of the Borrower and its
Subsidiaries is a corporation, partnership or limited liability company duly and
properly incorporated or organized, as the case may be, validly existing and (to
the extent such concept applies to such entity) in good standing under the laws
of its jurisdiction of incorporation or organization and has all requisite
authority to conduct its business in each jurisdiction in which its business is
conducted.

         5.2      Authorization and Validity. The Borrower has the corporate
power and authority and legal right to execute and deliver the Loan Documents
and to perform its obligations thereunder. The execution and delivery by the
Borrower of the Loan Documents and the performance of its obligations thereunder
have been duly authorized by proper corporate proceedings. After giving effect
to each Credit Extension hereunder, the aggregate amount of all Indebtedness and
borrowings of the Borrower will not exceed the maximum amount of Indebtedness
and borrowings authorized by the Borrower's Board of Directors. The Loan
Documents constitute legal, valid and binding obligations of the Borrower
enforceable against the Borrower in accordance with their terms, except as
enforceability may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors' rights generally.

                                       27


         5.3      No Conflict; Government Consent. Neither the execution and
delivery by the Borrower of the Loan Documents, nor the consummation of the
transactions therein contemplated, nor compliance with the provisions thereof
will violate (i) any law, rule, regulation, order, writ, judgment, injunction,
decree or award binding on the Borrower or any of its Subsidiaries, or (ii) the
Borrower's or any Subsidiary's articles or certificate of incorporation,
partnership agreement, certificate of partnership, articles or certificate of
organization, bylaws, or operating or other management agreement, as the case
may be, or (iii) the provisions of any indenture, instrument or agreement to
which the Borrower or any of its Subsidiaries is a party or is subject, or by
which it, or its Property, is bound, or conflict with or constitute a default
thereunder, or result in, or require, the creation or imposition of any Lien in,
of or on the Property of the Borrower or a Subsidiary pursuant to the terms of
any such indenture, instrument or agreement. No order, consent, adjudication,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, or other action in respect of any
governmental or public body or authority, or any subdivision thereof, which has
not been obtained by the Borrower or any of its Subsidiaries and is in full
force and effect, is required to be obtained by the Borrower or any of its
Subsidiaries in connection with the execution and delivery of the Loan
Documents, the borrowings under this Agreement, the payment and performance by
the Borrower of the Obligations or the legality, validity, binding effect or
enforceability of any of the Loan Documents, except that the Borrower is
required to make a notice filing with the SEC pursuant to the SEC's Rule 52
adopted pursuant to the Public Utility Holding Company Act of 1935, as amended.
The Borrower covenants that it will make the notice filing referred to in the
preceding sentence within the time limited prescribed therefor and further
represents that no further consent, approval, license, authorization or
validation of the SEC is required in connection therewith.

         5.4      Financial Statements. The September 30, 2002 consolidated
financial statements of the Borrower and its Subsidiaries heretofore delivered
to the Lenders were prepared in accordance with generally accepted accounting
principles in effect on the date such statements were prepared and fairly
present the consolidated financial condition and operations of the Borrower and
its Subsidiaries at such date and the consolidated results of their operations
for the period then ended.

         5.5      Material Adverse Change. Since September 30, 2002 no event has
occurred which could reasonably be expected to have a Material Adverse Effect.

         5.6      Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes due pursuant to said returns or pursuant to any
assessment received by the Borrower or any of its Subsidiaries, except such
taxes, if any, as are being contested in good faith and as to which adequate
reserves have been provided in accordance with Agreement Accounting Principles
and as to which no Lien exists. The United States income tax returns of the
Borrower and its Subsidiaries have been audited by the Internal Revenue Service
through the fiscal year ended July 31, 1997. No tax liens have been filed
against the Borrower or any Subsidiary. The charges, accruals and reserves on
the books of the Borrower and its Subsidiaries in respect of any taxes or other
governmental charges are adequate.

                                       28


         5.7      Litigation and Contingent Obligations. Except as described on
Schedule 5.7 or in the Borrower's annual report on Form 10K for the year ended
December 31, 2001 and the Borrower's quarterly reports on Form 10Q for the
periods ended March 31, 2002, June 30, 2002 and September 30, 2002, there is no
litigation, arbitration, governmental investigation, proceeding or inquiry
pending or, to the knowledge of any of their officers, threatened against or
affecting the Borrower or any of its Subsidiaries which could reasonably be
expected to have a Material Adverse Effect or which seeks to prevent, enjoin or
delay the making of any Loans. Other than any liability incident to any
litigation, arbitration or proceeding which could not reasonably be expected to
have a Material Adverse Effect, the Borrower has no material contingent
obligations not provided for or disclosed in the financial statements referred
to in Section 5.4.

         5.8      Subsidiaries. As of the date of this Agreement, the Borrower
has no Subsidiaries other than Southwestern Public Service Capital I.

         5.9      ERISA. The Unfunded Liabilities of all Single Employer Plans
do not in the aggregate exceed $25,000,000. Each Plan complies in all material
respects with all applicable requirements of law and regulations, no Reportable
Event has occurred with respect to any Plan, neither the Borrower nor any other
member of the Controlled Group (while it was a member of the Controlled Group)
has withdrawn from any Plan or initiated steps to do so, and no steps have been
taken to reorganize or terminate any Plan. Neither the Borrower nor any other
member of the Controlled Group is party to any Multiemployer Plan.

         5.10     Accuracy of Information. No information, exhibit or report
furnished by the Borrower or any of its Subsidiaries to the Agent or to any
Lender in connection with the negotiation of, or compliance with, the Loan
Documents contained any material misstatement of fact or omitted to state a
material fact or any fact necessary to make the statements contained therein not
misleading.

         5.11     Regulation U. Margin stock (as defined in Regulation U)
constitutes less than 25% of the value of those assets of the Borrower and its
Subsidiaries which are subject to any limitation on sale, pledge, or other
restriction hereunder.

         5.12     Material Agreements. Neither the Borrower nor any Subsidiary
is a party to any agreement or instrument or subject to any charter or other
corporate restriction which could reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in (i) any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect or (ii) any
agreement or instrument evidencing or governing Indebtedness.

         5.13     Compliance With Laws. The Borrower and its Subsidiaries have
complied in all material respects with all applicable statutes, rules,
regulations, orders and restrictions of any domestic or foreign government or
any instrumentality or agency thereof having jurisdiction over the conduct of
their respective businesses or the ownership of their respective Property.

                                       29


         5.14     Plan Assets; Prohibited Transactions. The Borrower is not an
entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA)
which is subject to Title I of ERISA or any plan (within the meaning of Section
4975 of the Code), and neither the execution of this Agreement nor the making of
Loans hereunder gives rise to a prohibited transaction within the meaning of
Section 406 of ERISA or Section 4975 of the Code.

         5.15     Environmental Matters. In the ordinary course of its business,
the officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
concluded that Environmental Laws cannot reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any Subsidiary has received
any notice to the effect that its operations are not in material compliance with
any of the requirements of applicable Environmental Laws or are the subject of
any federal or state investigation evaluating whether any remedial action is
needed to respond to a release of any toxic or hazardous waste or substance into
the environment, which noncompliance or remedial action could reasonably be
expected to have a Material Adverse Effect.

         5.16     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.

         5.17     Public Utility Holding Company Act. The Borrower is a
subsidiary of Xcel Energy Inc., which is a regulated "holding company" within
the meaning of the Public Utility Holding Company Act of 1935, as amended.

         5.18     Insurance. The Borrower and its Subsidiaries maintain a
self-insurance program and maintain with financially sound and reputable
insurance companies insurance on all their Property of a character usually
insured by entities in the same or similar businesses similarly situated against
loss or damage of the kinds and in the amounts, customarily insured against by
such entities, and maintain such other insurance as is usually carried by such
entities.

                                  ARTICLE VI.

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         8.1      Acceleration; Letter of Credit Collection Account.

         (i) If any Default described in Section 7.6 or 7.7 occurs with respect
to the Borrower, the obligations of the Lenders to make Loans hereunder and the
obligation and power of the Issuer to issue Letters of Credit shall
automatically terminate and the Obligations shall immediately become due and
payable without any election or action on the part of the Agent, any Lender or
the Issuer and the Borrower will be and become thereby unconditionally
obligated, without any further notice, act or demand, to pay to the Agent an
amount in immediately available funds, which funds shall be held in the Letter
of Credit Collateral Account, equal to the excess of (x) the amount of LC
Obligations at such time over (y) the amount on deposit in the Letter of Credit
Collateral Account at such time which is free and clear of all rights and claims
of third parties and has not been applied against the Obligations (such
difference, the "Collateral Shortfall Amount"). If any other Default occurs and
is continuing, the Required Lenders (or the Agent

                                       36


with the consent of the Required Lenders) may (a) terminate or suspend the
obligations of the Lenders to make Loans hereunder and the obligation and power
of the Issuer to issue Letters of Credit, or declare the Obligations to be due
and payable, or both, whereupon the Obligations shall become immediately due and
payable, without presentment, demand, protest or notice of any kind, all of
which the Borrower hereby expressly waives, and/or (b) upon notice to the
Borrower and in addition to the continuing right to demand payment of all
amounts payable under this Agreement, make demand on the Borrower to pay, and
the Borrower will, forthwith upon such demand and without any further notice or
act, pay to the Agent in immediately available funds the Collateral Shortfall
Amount, which funds shall be deposited in the Letter of Credit Collateral
Account.

         (ii) If at any time while any Default exists, the Agent determines that
the Collateral Shortfall Amount at such time is greater than zero, the Agent may
make demand on the Borrower to pay, and the Borrower will, forthwith upon such
demand and without any further notice or act, pay to the Agent in immediately
available funds the Collateral Shortfall Amount, which funds shall be deposited
in the Letter of Credit Collateral Account.

         (iii) The Agent may at any time or from time to time, after funds are
deposited in the Letter of Credit Collateral Account, apply such funds to the
payment of the Obligations and any other amounts as shall from time to time have
become due and payable by the Borrower to the Lenders or the Issuer under the
Loan Documents.

         (iv) At any time while any Default is continuing, neither the Borrower
nor any Person claiming on behalf of or through the Borrower shall have any
right to withdraw any of the funds held in the Letter of Credit Collateral
Account. After all of the Obligations have been indefeasibly paid in full and
the Aggregate Commitment has been terminated, any funds remaining in the Letter
of Credit Collateral Account shall be returned by the Agent to the Borrower or
paid to whomever may be legally entitled thereto at such time.

         If, within 30 days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans
hereunder as a result of any Default (other than any Default as described in
Section 7.6 or 7.7 with respect to the Borrower) and before any judgment or
decree for the payment of the Obligations due shall have been obtained or
entered, the Required Lenders (in their sole discretion) shall so direct, the
Agent shall, by notice to the Borrower, rescind and annul such acceleration
and/or termination.

         8.2      Amendments. Subject to the provisions of this Article VIII,
the Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or waiving any
Default hereunder; provided, however, that no such supplemental agreement shall,
without the consent of all of the Lenders:

         (i)      Extend the final maturity of any Loan or the Final Maturity
                  Date, or extend the expiry date of any Letter of Credit to a
                  date after the Facility Termination Date, forgive all or any
                  portion of the principal amount thereof, or reduce the rate or

                                       37


                  extend the time of payment of interest or fees thereon or any
                  Reimbursement Obligation related thereto.

         (ii)     Reduce the percentage specified in the definition of Required
                  Lenders.

         (iii)    Extend the Facility Termination Date, or reduce the amount or
                  extend the payment date for, the mandatory payments required
                  under Section 2.2, or increase the amount of the Aggregate
                  Commitment or of the Commitment of any Lender hereunder, or
                  permit the Borrower to assign its rights under this Agreement.

         (iv)     Amend this Section 8.2.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent, and no amendment of any
provision to this Agreement relating to the Issuer shall be effective without
the written consent of the Issuer. The Agent may waive payment of the fee
required under Section 12.3.2 without obtaining the consent of any other party
to this Agreement.

         8.3      Preservation of Rights. No delay or omission of the Lenders,
the Issuer or the Agent to exercise any right under the Loan Documents shall
impair such right or be construed to be a waiver of any Default or an
acquiescence therein, and the making of a Credit Extension notwithstanding the
existence of a Default or the inability of the Borrower to satisfy the
conditions precedent to such Credit Extension shall not constitute any waiver or
acquiescence. Any single or partial exercise of any such right shall not
preclude other or further exercise thereof or the exercise of any other right,
and no waiver, amendment or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by the Lenders required pursuant to Section 8.2, and then only to the
extent in such writing specifically set forth. All remedies contained in the
Loan Documents or by law afforded shall be cumulative and all shall be available
to the Agent, the Lenders and the Issuer until the Obligations have been paid in
full.

                                  ARTICLE IX.

                               GENERAL PROVISIONS

         9.1      Survival of Representations. All representations and
warranties of the Borrower contained in this Agreement shall survive the making
of the Credit Extensions herein contemplated.

         9.2      Governmental Regulation. Anything contained in this Agreement
to the contrary notwithstanding, no Issuer or Lender shall be obligated to
extend credit to the Borrower in violation of any limitation or prohibition
provided by any applicable statute or regulation.

         9.3      Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

                                       38


         9.4      Entire Agreement. The Loan Documents embody the entire
agreement and understanding among the Borrower, the Agent, the Lenders and the
Issuer and supersede all prior agreements and understandings among the Borrower,
the Agent, the Lenders and the Issuer relating to the subject matter thereof
other than the fee letter described in Section 10.13.

         9.5      Several Obligations; Benefits of this Agreement. The
respective obligations of the Lenders hereunder are several and not joint and no
Lender shall be the partner or agent of any other (except to the extent to which
the Agent is authorized to act as such). The failure of any Lender to perform
any of its obligations hereunder shall not relieve any other Lender from any of
its obligations hereunder. This Agreement shall not be construed so as to confer
any right or benefit upon any Person other than the parties to this Agreement
and their respective successors and assigns, provided that the parties hereto
expressly agree that the Arranger shall enjoy the benefits of the provisions of
Sections 9.6, 9.10 and 10.11 to the extent specifically set forth therein and
shall have the right to enforce such provisions on its own behalf and in its own
name to the same extent as if it were a party to this Agreement.

         9.6      Expenses; Indemnification. (i) The Borrower shall reimburse
the Agent and the Arranger for all reasonable costs, internal charges and
out-of-pocket expenses (including reasonable attorneys' fees and reasonable time
charges of attorneys for the Agent, which attorneys may be employees of the
Agent) paid or incurred by the Agent or the Arranger in connection with the
preparation, negotiation, execution, delivery, syndication, review, amendment,
modification, and administration of the Loan Documents. The Borrower also agrees
to reimburse the Agent, the Arranger, the Lenders and the Issuer for all
reasonable costs, internal charges and out-of-pocket expenses (including
reasonable attorneys' fees and reasonable time charges of attorneys for the
Agent, the Arranger, the Lenders and the Issuer, which attorneys may be
employees of the Agent, the Arranger, the Lenders or the Issuer) paid or
incurred by the Agent, the Arranger, any Lender or the Issuer in connection with
the collection and enforcement of the Loan Documents.

         (ii) The Borrower hereby further agrees to indemnify the Agent, the
Arranger, each Lender, the Issuer, their respective affiliates, and each of
their directors, officers and employees against all losses, claims, damages,
penalties, judgments, liabilities and reasonable expenses (including, without
limitation, all reasonable expenses of litigation or preparation therefor
whether or not the Agent, the Arranger, any Lender, the Issuer or any affiliate
is a party thereto) which any of them may pay or incur arising out of or
relating to this Agreement, the other Loan Documents, the transactions
contemplated hereby or the direct or indirect application or proposed
application of the proceeds of any Credit Extension hereunder except to the
extent that they are determined in a final non-appealable judgment by a court of
competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the party seeking indemnification. The obligations of the Borrower
under this Section 9.6 shall survive the termination of this Agreement.

         9.7      Numbers of Documents. All statements, notices, closing
documents, and requests hereunder shall be furnished to the Agent with
sufficient counterparts so that the Agent may furnish one to each of the
Lenders.

                                       39


         9.8      Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

         9.9      Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         9.10     Nonliability of Lenders. The relationship between the Borrower
on the one hand and the Lenders, the Issuer and the Agent on the other hand
shall be solely that of borrower and lender. Neither the Agent, the Arranger,
any Lender nor the Issuer shall have any fiduciary responsibilities to the
Borrower. Neither the Agent, the Arranger, any Lender nor the Issuer undertakes
any responsibility to the Borrower to review or inform the Borrower of any
matter in connection with any phase of the Borrower's business or operations.
The Borrower agrees that neither the Agent, the Arranger, any Lender nor the
Issuer shall have liability to the Borrower (whether sounding in tort, contract
or otherwise) for losses suffered by the Borrower in connection with, arising
out of, or in any way related to, the transactions contemplated and the
relationship established by the Loan Documents, or any act, omission or event
occurring in connection therewith, unless it is determined in a final
non-appealable judgment by a court of competent jurisdiction that such losses
resulted from the gross negligence or willful misconduct of the party from which
recovery is sought. Neither the Agent, the Arranger, any Lender nor the Issuer
shall have any liability with respect to, and the Borrower hereby waives,
releases and agrees not to sue for, any special, indirect or consequential
damages suffered by the Borrower in connection with, arising out of, or in any
way related to the Loan Documents or the transactions contemplated thereby.

         9.11     Limited Disclosure. (a) Notwithstanding anything to the
contrary herein, the Borrower, each Lender and the Agent hereby agree that, from
the commencement of discussions with respect to the facility established by this
Agreement (the "Facility"), the Borrower, each Lender and the Agent (and each of
their respective, and their respective Affiliates', employees, officers,
directors, representatives, advisors and agents) are permitted to disclose to
any and all Persons, without limitation of any kind, the structure and tax
aspects (as such terms are used in sections 6011 and 6111 of the Code) of the
Facility, and all materials or any kind (including opinions or other tax
analyses) that are provided to the Borrower, any Lender or the Agent related to
such structure and tax aspects. In this regard, each of the Borrower, each
Lender and the Agent acknowledges and agrees that the disclosure of the
structure or tax aspects of the Facility is not limited in any way by an express
or implied understanding or agreement, oral or written (whether or not such
understanding or agreement is legally binding). Furthermore, each of the
Borrower, each Lender and the Agent acknowledges and agrees that it does not
know or have reason to know that its use or disclosure of information relating
to the structure or tax aspects of the Facility is limited in any other manner
(such as where the Facility is claimed to be proprietary or exclusive) for the
benefit of any other Person.

         (b) Neither the Agent nor any Lender may disclose to any Person any
Specified Information (as defined below) except to its, and its Affiliates',
officers, employees, agents,

                                       40


accountants, legal counsel, advisors and other representatives who have a need
to know such Specified Information. "Specified Information" means information
that the Borrower furnishes to the Agent or any Lender in a writing designated
as confidential, but does not include any such information that (i) relates to
the "structure" or "tax aspects" of the transactions contemplated by this
Agreement, as such terms are used in Sections 6011, 6111 and 6112 of the Code
and the regulations promulgated thereunder or (ii) is or becomes generally
available to the public or that is or becomes available to the Agent or such
Lender from a source other than the Borrower.

         (c) The provisions of subsection (b) above shall not apply to Specified
Information (i) that is a matter of general public knowledge or has heretofore
been or is hereafter published in any source generally available to the public,
(ii) that is required to be disclosed by law, regulation or judicial order,
including pursuant to the tax shelter regulations under Sections 6011, 6111 and
6112 of the Code, (iii) that is requested by any regulatory body with
jurisdiction over the Agent or any Lender, or (iv) that is disclosed to legal
counsel, accountants and other professional advisors to such Lender, in
connection with the exercise of any right or remedy hereunder or under any Note
or any suit or other litigation or proceeding relating to this Agreement or any
Note, to a rating agency if required by such agency in connection with a rating
relating to Credit Extensions hereunder or to assignees or participants or
potential assignees or participants who agree to be bound by the provisions of
this Section 9.11.

         (d) The provisions of this Section 9.11 supersede any confidentiality
obligations of any Lender or the Agent relating to the Facility under any
agreement between the Borrower and any such party. The parties hereto agree that
any such confidentiality obligations of any Lender or the Agent shall be deemed
void ab initio to the extent the same relate to the Facility.

         9.12     Nonreliance. Each Lender hereby represents that it is not
relying on or looking to any margin stock (as defined in Regulation U of the
Board of Governors of the Federal Reserve System) for the repayment of the
Credit Extensions provided for herein.

         9.13     Disclosure. The Borrower, each Lender and the Issuer hereby
(i) acknowledge and agree that Bank One and/or its Affiliates from time to time
may hold investments in, make other loans to or have other relationships with
the Borrower and its Affiliates, and (ii) waive any liability of Bank One or
such Affiliate of Bank One to the Borrower or any Lender, respectively, arising
out of or resulting from such investments, loans or relationships other than
liabilities arising out of the gross negligence or willful misconduct of Bank
One or its Affiliates.

                                   ARTICLE X.

                                   THE AGENT

         10.1     Appointment; Nature of Relationship. Bank One, is hereby
appointed by each of the Lenders as its contractual representative (herein
referred to as the "Agent") hereunder and under each other Loan Document, and
each of the Lenders irrevocably authorizes the Agent to act as the contractual
representative of such Lender with the rights and duties expressly set forth
herein and in the other Loan Documents. The Agent agrees to act as such
contractual representative upon the express conditions contained in this Article
X. Notwithstanding the use of the defined term "Agent," it is expressly
understood and agreed that the Agent shall not have

                                       41


any fiduciary responsibilities to any Lender by reason of this Agreement or any
other Loan Document and that the Agent is merely acting as the contractual
representative of the Lenders with only those duties as are expressly set forth
in this Agreement and the other Loan Documents. In its capacity as the Lenders'
contractual representative, the Agent (i) does not hereby assume any fiduciary
duties to any of the Lenders, (ii) is a "representative" of the Lenders within
the meaning of Section 9-105 of the Uniform Commercial Code and (iii) is acting
as an independent contractor, the rights and duties of which are limited to
those expressly set forth in this Agreement and the other Loan Documents. Each
of the Lenders hereby agrees to assert no claim against the Agent on any agency
theory or any other theory of liability for breach of fiduciary duty, all of
which claims each Lender hereby waives.

         10.2     Powers. The Agent shall have and may exercise such powers
under the Loan Documents as are specifically delegated to the Agent by the terms
of each thereof, together with such powers as are reasonably incidental thereto.
The Agent shall have no implied duties to the Lenders, or any obligation to the
Lenders to take any action thereunder except any action specifically provided by
the Loan Documents to be taken by the Agent.

         10.3     General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
to the extent such action or inaction is determined in a final non-appealable
judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

         10.4     No Responsibility for Loans, Recitals, etc. Neither the Agent
nor any of its directors, officers, agents or employees shall be responsible for
or have any duty to ascertain, inquire into, or verify (a) any statement,
warranty or representation made in connection with any Loan Document or any
borrowing hereunder; (b) the performance or observance of any of the covenants
or agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (c) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered solely to the Agent; (d) the existence
or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith, or (f) the
financial condition of the Borrower or of any of the Borrower's Subsidiaries.
The Agent shall have no duty to disclose to the Lenders information that is not
required to be furnished by the Borrower to the Agent at such time, but is
voluntarily furnished by the Borrower to the Agent (either in its capacity as
Agent or in its individual capacity).

         10.5     Action on Instructions of Lenders. The Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder and
under any other Loan Document in accordance with written instructions signed by
the Required Lenders (or, when expressly required hereunder, all of the
Lenders), and such instructions and any action taken or failure to act pursuant
thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge
that the Agent shall be under no duty to take any discretionary action permitted
to be taken by it pursuant to the provisions of this Agreement or any other Loan
Document unless it shall be requested in writing to do so by the Required
Lenders. The Agent shall be fully justified in

                                       42


failing or refusing to take any action hereunder and under any other Loan
Document unless it shall first be indemnified to its satisfaction by the Lenders
pro rata against any and all liability, cost and expense that it may incur by
reason of taking or continuing to take any such action.

         10.6     Employment of Agents and Counsel. The Agent may execute any of
its duties as Agent hereunder and under any other Loan Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters pertaining to the Agent's duties hereunder and under any other
Loan Document.

         10.7     Reliance on Documents; Counsel. The Agent shall be entitled to
rely upon any Note, notice, consent, certificate, affidavit, letter, telegram,
statement, paper or document believed by it to be genuine and correct and to
have been signed or sent by the proper person or persons, and, in respect to
legal matters, upon the opinion of counsel selected by the Agent, which counsel
may be employees of the Agent.

         10.8     Agent's Reimbursement and Indemnification. The Lenders agree
to reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan Documents, (ii) for any other expenses incurred by
the Agent on behalf of the Lenders, in connection with the preparation,
execution, delivery, administration and enforcement of the Loan Documents
(including, without limitation, for any expenses incurred by the Agent in
connection with any dispute between the Agent and any Lender or between two or
more of the Lenders) and (iii) for any liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever which may be imposed on, incurred by or
asserted against the Agent in any way relating to or arising out of the Loan
Documents or any other document delivered in connection therewith or the
transactions contemplated thereby (including, without limitation, for any such
amounts incurred by or asserted against the Agent in connection with any dispute
between the Agent and any Lender or between two or more of the Lenders), or the
enforcement of any of the terms of the Loan Documents or of any such other
documents, provided that (i) no Lender shall be liable for any of the foregoing
to the extent any of the foregoing is found in a final non-appealable judgment
by a court of competent jurisdiction to have resulted from the gross negligence
or willful misconduct of the Agent and (ii) any indemnification required
pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this
Section 10.8, be paid by the relevant Lender in accordance with the provisions
thereof. The obligations of the Lenders under this Section 10.8 shall survive
payment of the Obligations and termination of this Agreement.

         10.9     Notice of Default. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Unmatured Default
hereunder unless the Agent has received written notice from a Lender or the
Borrower referring to this Agreement describing such Default or Unmatured
Default and stating that such notice is a "notice of default". In the event that
the Agent receives such a notice, the Agent shall give prompt notice thereof to
the Lenders.

                                       43


         10.10    Rights as a Lender. In the event the Agent is a Lender, the
Agent shall have the same rights and powers hereunder and under any other Loan
Document with respect to its Commitment and its Loans as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, at any time when the Agent is a Lender, unless the context
otherwise indicates, include the Agent in its individual capacity. The Agent and
its Affiliates may accept deposits from, lend money to, and generally engage in
any kind of trust, debt, equity or other transaction, in addition to those
contemplated by this Agreement or any other Loan Document, with the Borrower or
any of its Subsidiaries in which the Borrower or such Subsidiary is not
restricted hereby from engaging with any other Person. The Agent, in its
individual capacity, is not obligated to remain a Lender.

         10.11    Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Arranger or any other
Lender and based on the financial statements prepared by the Borrower and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and the other Loan
Documents. Each Lender also acknowledges that it will, independently and without
reliance upon the Agent, the Arranger or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement and the other Loan Documents.

         10.12    Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. The Agent may be removed at any time with or without cause
by written notice received by the Agent from the Required Lenders, such removal
to be effective on the date specified by the Required Lenders; provided that the
Agent may not be removed unless the Agent (in its individual capacity) and any
affiliate thereof acting as Issuer is relieved of all of its duties as Issuer
pursuant to documentation reasonably satisfactory to such Person on or prior to
the date of such removal. Upon any such resignation or removal, the Required
Lenders shall have the right to appoint, on behalf of the Borrower and the
Lenders, a successor Agent. If no successor Agent shall have been so appointed
by the Required Lenders within thirty days after the resigning Agent's giving
notice of its intention to resign, then the resigning Agent may appoint, on
behalf of the Borrower and the Lenders, a successor Agent. Notwithstanding the
previous sentence, the Agent may at any time without the consent of any Lender
and with the consent of the Borrower, not to be unreasonably withheld or
delayed, appoint any of its Affiliates which is a commercial bank as a successor
Agent hereunder. If the Agent has resigned or been removed and no successor
Agent has been appointed, the Lenders may perform all the duties of the Agent
hereunder and the Borrower shall make all payments in respect of the Obligations
to the applicable Lender and for all other purposes shall deal directly with the
Lenders. No successor Agent shall be deemed to be appointed hereunder until such
successor Agent has accepted the appointment. Any such successor Agent shall be
a commercial bank having capital and retained earnings of at least $100,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning or removed Agent. Upon
the effectiveness of the resignation or removal of the Agent, the resigning or
removed Agent shall be discharged from its duties and obligations hereunder and
under the Loan Documents. After the effectiveness of the resignation or removal
of an Agent,

                                       44


the provisions of this Article X shall continue in effect for the benefit of
such Agent in respect of any actions taken or omitted to be taken by it while it
was acting as the Agent hereunder and under the other Loan Documents. In the
event that there is a successor to the Agent by merger, or the Agent assigns its
duties and obligations to an Affiliate pursuant to this Section 10.12, then the
term "Prime Rate" as used in this Agreement shall mean the prime rate, base rate
or other analogous rate of the new Agent.

         10.13    Agent's Fee. The Borrower agrees to pay to the Agent, for its
own account, the fees agreed to by the Borrower and the Agent pursuant to that
certain letter agreement dated January 23, 2003, or as otherwise agreed from
time to time.

         10.14    Delegation to Affiliates. The Borrower and the Lenders agree
that the Agent may delegate any of its duties under this Agreement to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection with this Agreement shall be
entitled to the same benefits of the indemnification, waiver and other
protective provisions to which the Agent is entitled under Articles IX and X.

         10.15    Syndication Agent. No Lender identified on the cover page, the
signature pages or otherwise in this Agreement, or in any document related
hereto, as being the "Syndication Agent" shall have any right, power,
obligation, liability, responsibility or duty under this Agreement in such
capacity other than those applicable to all Lenders. Each Lender acknowledges
that it has not relied, and will not rely, on the Syndication Agent in deciding
to enter into this Agreement or in taking or refraining from taking any action
hereunder or pursuant hereto.

                                  ARTICLE XI.

                            SETOFF; RATABLE PAYMENTS

         11.1     Setoff. In addition to, and without limitation of, any rights
of the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender or
any Affiliate of any Lender to or for the credit or account of the Borrower may
be offset and applied toward the payment of the Obligations owing to such
Lender, whether or not the Obligations, or any part thereof, shall then be due.

         11.2     Ratable Payments. If any Lender, whether by setoff or
otherwise, has payment made to it upon its Outstanding Credit Exposure (other
than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5 and payments
made to the Issuer in respect of Reimbursement Obligations so long as the
Lenders have not funded their participations therein) in a greater proportion
than that received by any other Lender, such Lender agrees, promptly upon
demand, to purchase a portion of the Aggregate Outstanding Credit Exposure held
by the other Lenders so that after such purchase each Lender will hold its
ratable proportion of the Aggregate Outstanding Credit Exposure. If any Lender,
whether in connection with setoff or amounts which might be subject to setoff or
otherwise, receives collateral or other protection for its Obligations or such
amounts which may be subject to setoff, such Lender agrees, promptly upon

                                       45


demand, to take such action necessary such that all Lenders share in the
benefits of such collateral ratably in proportion to their Aggregate Outstanding
Credit Exposure. In case any such payment is disturbed by legal process, or
otherwise, appropriate further adjustments shall be made.

                                  ARTICLE XII.

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         12.1     Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (i) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents and (ii) any assignment by any Lender must be made in compliance
with Section 12.3. The parties to this Agreement acknowledge that clause (ii) of
this Section 12.1 relates only to absolute assignments and does not prohibit
assignments creating security interests, including, without limitation, any
pledge or assignment by any Lender of all or any portion of its rights under
this Agreement and any Note to a Federal Reserve Bank; provided that no such
pledge or assignment creating a security interest shall release the transferor
Lender from its obligations hereunder unless and until the parties thereto have
complied with the provisions of Section 12.3. The Agent may treat the Person
which made any Loan or which holds any Note as the owner thereof for all
purposes hereof unless and until such Person complies with Section 12.3;
provided that the Agent may in its discretion (but shall not be required to)
follow instructions from the Person which made any Loan or which holds any Note
to direct payments relating to such Loan or Note to another Person. Any assignee
of the rights to any Loan or any Note agrees by acceptance of such assignment to
be bound by all the terms and provisions of the Loan Documents. Any request,
authority or consent of any Person, who at the time of making such request or
giving such authority or consent is the owner of the rights to any Loan (whether
or not a Note has been issued in evidence thereof), shall be conclusive and
binding on any subsequent holder or assignee of the rights to such Loan.

         12.2     Participations.

                  12.2.1   Permitted Participants; Effect. Any Lender may, in
         the ordinary course of its business and in accordance with applicable
         law, at any time sell to one or more banks or other entities
         ("Participants") participating interests in any Outstanding Credit
         Exposure owing to such Lender, any Note held by such Lender, any
         Commitment of such Lender or any other interest of such Lender under
         the Loan Documents. In the event of any such sale by a Lender of
         participating interests to a Participant, such Lender's obligations
         under the Loan Documents shall remain unchanged, such Lender shall
         remain solely responsible to the other parties hereto for the
         performance of such obligations, such Lender shall remain the owner of
         its Outstanding Credit Exposure and the holder of any Note issued to it
         in evidence thereof for all purposes under the Loan Documents, all
         amounts payable by the Borrower under this Agreement shall be
         determined as if such Lender had not sold such participating interests,
         and the Borrower and the Agent shall continue to deal solely and
         directly with such Lender in connection with such Lender's rights and
         obligations under the Loan Documents.

                                       46


                  12.2.2   Voting Rights. Each Lender shall retain the sole
         right to approve, without the consent of any Participant, any
         amendment, modification or waiver of any provision of the Loan
         Documents other than any amendment, modification or waiver with respect
         to any Credit Extension or Commitment in which such Participant has an
         interest which forgives principal, interest, fees or Reimbursement
         Obligations or reduces the interest rate or fees payable with respect
         to any such Credit Extension or Commitment, extends the Facility
         Termination Date or the Final Maturity Date, or postpones any date
         fixed for any regularly scheduled payment of principal of, or interest
         or fees on, any such Credit Extension or Commitment.

                  12.2.3   Benefit of Setoff. The Borrower agrees that each
         Participant shall be deemed to have the right of setoff provided in
         Section 11.1 in respect of its participating interest in amounts owing
         under the Loan Documents to the same extent as if the amount of its
         participating interest were owing directly to it as a Lender under the
         Loan Documents, provided that each Lender shall retain the right of
         setoff provided in Section 11.1 with respect to the amount of
         participating interests sold to each Participant. The Lenders agree to
         share with each Participant, and each Participant, by exercising the
         right of setoff provided in Section 11.1, agrees to share with each
         Lender, any amount received pursuant to the exercise of its right of
         setoff, such amounts to be shared in accordance with Section 11.2 as if
         each Participant were a Lender.

         12.3     Assignments.

                  12.3.1   Permitted Assignments. Any Lender may, in the
         ordinary course of its business and in accordance with applicable law,
         at any time assign to one or more banks or other entities
         ("Purchasers") all or any part of its rights and obligations under the
         Loan Documents. Such assignment shall be substantially in the form of
         Exhibit C or in such other form as may be agreed to by the parties
         thereto. The consent of the Borrower and the Agent shall be required
         prior to an assignment becoming effective with respect to a Purchaser
         which is not a Lender or an Affiliate thereof; provided that if a
         Default has occurred and is continuing, the consent of the Borrower
         shall not be required. Such consent shall not be unreasonably withheld
         or delayed. Each such assignment with respect to a Purchaser which is
         not a Lender or an Affiliate thereof shall (unless each of the Borrower
         and the Agent otherwise consents) be in an amount not less than the
         lesser of (i) $10,000,000 or (ii) the remaining amount of the assigning
         Lender's Commitment (calculated as at the date of such assignment) or
         outstanding Loans (if the applicable Commitment has been terminated).

                  12.3.2   Effect; Effective Date. Upon (i) delivery to the
         Agent of an assignment, together with any consents required by Section
         12.3.1, and (ii) payment of a $3,500 fee to the Agent for processing
         such assignment (unless such fee is waived by the Agent), such
         assignment shall become effective on the effective date specified in
         such assignment. The assignment shall contain a representation by the
         Purchaser to the effect that none of the consideration used to make the
         purchase of the Commitment and Outstanding Credit Exposure under the
         applicable assignment agreement constitutes "plan assets" as defined
         under ERISA and that the rights and interests of the Purchaser in and
         under the Loan Documents will not be "plan assets" under ERISA. On and
         after the effective date of

                                       47


         such assignment, such Purchaser shall for all purposes be a Lender
         party to this Agreement and any other Loan Document executed by or on
         behalf of the Lenders and shall have all the rights and obligations of
         a Lender under the Loan Documents, to the same extent as if it were an
         original party hereto, and no further consent or action by the
         Borrower, the Lenders or the Agent shall be required to release the
         transferor Lender with respect to the percentage of the Aggregate
         Commitment and the Aggregate Outstanding Credit Exposure assigned to
         such Purchaser. Upon the consummation of any assignment to a Purchaser
         pursuant to this Section 12.3.2, the transferor Lender, the Agent and
         the Borrower shall, if the transferor Lender or the Purchaser desires
         that its Loans be evidenced by Notes, make appropriate arrangements so
         that new Notes or, as appropriate, replacement Notes are issued to such
         transferor Lender and new Notes or, as appropriate, replacement Notes,
         are issued to such Purchaser, in each case in principal amounts
         reflecting their respective Commitments, as adjusted pursuant to such
         assignment.

         12.4     Dissemination of Information. The Borrower authorizes each
Lender to disclose to any Participant or Purchaser or any other Person acquiring
an interest in the Loan Documents by operation of law (each a "Transferee") and
any prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries, including
without limitation any information contained in any Reports; provided that each
Transferee and prospective Transferee agrees to be bound by Section 9.11 of this
Agreement.

         12.5     Tax Treatment. If any interest in any Loan Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.5(iv).

                                 ARTICLE XIII.

                                   NOTICES

         13.1     Notices. Except as otherwise permitted by Section 2.14 with
respect to borrowing notices, all notices, requests and other communications to
any party hereunder shall be in writing (including electronic transmission,
facsimile transmission or similar writing) and shall be given to such party: (x)
in the case of the Borrower or the Agent, at its address or facsimile number set
forth on the signature pages hereof, (y) in the case of any Lender, at its
address or facsimile number set forth in its administrative questionnaire or (z)
in the case of any party, at such other address or facsimile number as such
party may hereafter specify for the purpose by notice to the Agent and the
Borrower in accordance with the provisions of this Section 13.1. Each such
notice, request or other communication shall be effective (i) if given by
facsimile transmission, when transmitted to the facsimile number specified in
this Section and confirmation of receipt is received, or (ii) if given by any
other means, when delivered (or, in the case of electronic transmission,
received) at the address specified in this Section; provided that notices to the
Agent under Article II shall not be effective until received.

         13.2     Change of Address. The Borrower, the Agent and any Lender may
each change the address for service of notice upon it by a notice in writing to
the other parties hereto.

                                       48



                                  ARTICLE XIV.

                                  COUNTERPARTS

         This Agreement may be executed in any number of counterparts, all of
which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective when it has been executed by the Borrower, the
Agent and the Lenders and each party has notified the Agent by facsimile
transmission or telephone that it has taken such action.

                                   ARTICLE XV.

                     CHOICE OF LAW; CONSENT TO JURISDICTION;
                   WAIVER OF JURY TRIAL; MAXIMUM INTEREST RATE

         15.1     CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING
A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE
WITH THE INTERNAL LAWS (INCLUDING, WITHOUT LIMITATION, 735 ILCS SECTION 105/5-1
ET SEQ, BUT OTHERWISE WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE
STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL
BANKS.

         15.2     CONSENT TO JURISDICTION. THE BORROWER HEREBY IRREVOCABLY
SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR
ILLINOIS STATE COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING
ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY
IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY
BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION
IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR
PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM.
NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT, ANY LENDER OR THE ISSUER TO
BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.
ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY LENDER OR ANY
AFFILIATE OF THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY
MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN
DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN CHICAGO, ILLINOIS.

         15.3     WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT, THE ISSUER AND
EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING,
DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR
OTHERWISE) IN ANY WAY

                                       49



ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE
RELATIONSHIP ESTABLISHED THEREUNDER.

         15.4     Maximum Interest Rate. No provision of the Loan Documents
shall require the payment or permit the collection of interest in excess of the
maximum permitted by applicable law ("Maximum Rate"). If any interest in excess
of the Maximum Rate is provided for or shall be adjudicated to be provided for
in the Notes or otherwise in connection with this Agreement, the provisions of
this Section 15.4 shall govern and prevail and neither the Borrower nor the
sureties, guarantors, successors or assigns of the Borrower shall be obligated
to pay the excess amount of the interest or any other excess sum paid for the
use, forbearance, or detention of sums loaned. In the event the Agent or any
Lender ever receives, collects or applies as interest any amount in excess of
the Maximum Rate, the amount by which such amount exceeds the Maximum Rate shall
be applied as a payment and reduction of the principal of indebtedness evidenced
by the Loans, and, if the principal amount of the Loans has been paid in full,
any remaining excess shall forthwith be paid to the Borrower.

                                       50



         IN WITNESS WHEREOF, the Borrower, the Lenders and the Agent have
executed this Agreement as of the date first above written.

         For the purposes of this Schedule, the following terms have the
following meanings, subject to the final paragraph of this Schedule:

         "Level I Status" exists at any date if, on such date, the Borrower's
Moody's Rating is A3 or better and the Borrower's S&P Rating is A- or better.

         "Level II Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status and (ii) the Borrower's Moody's Rating is
Baa1 or better and the Borrower's S&P Rating is BBB+ or better.

         "Level III Status" exists at any date if, on such date, (i) the
Borrower has not qualified for Level I Status or Level II Status; and (ii) the
Borrower's Moody's Rating is Baa2 or better and the Borrower's S&P Rating is BBB
or better.

         "Level IV Status" exists at any date if, on such date, (i) the Borrower
has not qualified for Level I Status, Level II Status or Level III Status; and
(ii) the Borrower's Moody's Rating is Baa3 or better and the Borrower's S&P
Rating is BBB- or better.

         "Level V Status" exists at any date if, on such date, the Borrower has
not qualified for Level I Status, Level II Status, Level III Status or Level IV
Status.

         "Moody's Rating" means, at any time, the rating issued by Moody's and
then in effect with respect to the Borrower's senior unsecured long-term debt
securities without third-party credit enhancement.

         "S&P Rating" means, at any time, the rating issued by S&P and then in
effect with respect to the Borrower's senior unsecured long-term debt securities
without third-party credit enhancement.



         "Status" means Level I Status, Level II Status, Level III Status, Level
IV Status or Level V Status.

         The Applicable Margin, the Commitment Fee Rate and the Letter of Credit
Fee Rate shall be determined in accordance with the foregoing table based on the
Borrower's Status as determined from its then-current Moody's and S&P Ratings.
The credit rating in effect on any date for the purposes of this Schedule is
that in effect at the close of business on such date. If at any time the
Borrower has no Moody's Rating or no S&P Rating, Level V Status shall exist.



                                  SCHEDULE 5.7

                       LITIGATION; CONTINGENT LIABILITIES

         On July 24, 1995, Lamb County Electric Cooperative, Inc. (LCEC)
petitioned the Public Utility Commission of Texas (PUCT) for a cease and desist
order against the Borrower. LCEC alleged that the Borrower had been unlawfully
providing service to oil-field customers and their facilities in LCEC's singly
certificated area. The Borrower responded that it was lawfully entitled to serve
oil field customers under "grandfather rights" granted to it in the same order
that granted LCEC its certificated area. Ultimately, the Commission issued an
order granting the Borrower's motion for summary disposition, thus denying
LCEC's petition. LCEC appealed the Commission's order to district court, which
upheld the order. LCEC then appealed to the Third Court of Appeals, which
reversed the district court judgment and remanded the case to the Commission for
an evidentiary hearing. The LCEC complaint was transferred to the State Office
of Administrative Hearings (SOAH) for processing. A hearing on the merits was
held October 7-10, 2002, and we are currently waiting for a Proposal For
Decision from the SOAH Administrative Law Judge. In related litigation, on
October 18, 1996, LCEC filed an action for damages based on its claim that the
Borrower has been unlawfully providing service to oil field customers in its
certificated area. This case has remained dormant pending a final determination
by the PUCT of the lawfulness of the service. Damages resulting from a decision
adverse to the Borrower could be material.

                                  SCHEDULE 5.9

                           EXCLUDED REPORTABLE EVENTS

         Pursuant to 29 CFR Part 4043, Subparts A and B, a Reportable Event
occurred on November 22, 2002, when five former officers of NRG Energy, Inc. a
wholly owned subsidiary of Xcel Energy Inc., filed an involuntary petition in
the United States Bankruptcy Court, District of Minnesota, alleging non-payment
of certain obligations arising out of their employment with NRG Energy, Inc.

         Xcel Energy Inc., as plan sponsor of the Xcel Energy Pension Plan, of
which NRG Energy, Inc. is a participating employer, has complied with the
Pension Benefit Guaranty Corporation's Reporting and Notification requirements,
and takes the position that the Involuntary Petition has no impact on the funded
status of the Xcel Energy Pension Plan.

                                 FORM OF OPINION

                                February 18, 2003

To:      The Agent and the Lenders who are parties to the
         Credit Agreement described below.

Re:      Southwestern Public Service Company

Ladies and Gentlemen:

         We have acted as counsel for Southwestern Public Service Company (the
"Borrower") and have represented the Borrower in connection with its execution
and delivery of a Credit Agreement dated as of February 18, 2003 (the
"Agreement"), among the Borrower, the Lenders named therein, Bank One, NA, as
Agent, The Bank of New York, as Syndication Agent, and Bank One Capital Markets,
Inc., as Lead Arranger and Sole Book Runner, providing for Credit Extensions in
an aggregate principal amount not exceeding $125,000,000 at any one time
outstanding. All capitalized terms used in this opinion and not otherwise
defined herein shall have the meanings attributed to them in the Agreement.

         We are not general counsel to the Borrower, and our representation
consists of advising the Borrower on corporate matters as to which we have been
specifically consulted. In connection with this opinion, we have examined the
originals or photocopies of the Agreement, the Notes executed and to be executed
by the Borrower, and such corporate records, agreements and instruments of the
Borrower, certificates of public officials and of officers of the Borrower, such
other documents and records, and such matters of law, as we have deemed
necessary or appropriate for purposes of the opinions rendered below. In such
examination, we have assumed the genuineness of all signatures (other than those
of the Borrower), the authenticity of all documents submitted to us as copies
and the authenticity of the originals of such latter documents. In addition,
where relevant facts were not independently established, we have relied as to
matters of fact (but not conclusions of law) upon the aforesaid agreements,
corporate records, instruments, documents and certificates, discussions with
officers and representatives of the Borrower, the representations and warranties
of the Borrower contained in the Agreement and the certificates of officers of
the Borrower being delivered to you in connection with the Agreement. In
rendering this opinion, we have also assumed that the Agreement has been duly
authorized, executed and delivered by, and is the legal, valid and binding
agreement of, and is enforceable against, the Lenders.

         Based on the foregoing examination, and subject to the limitations and
qualifications set forth in this letter, we are of the opinion that:

         1.       The Borrower is a corporation, duly and properly incorporated,
validly existing, and in good standing under the laws of New Mexico and has all
requisite authority to conduct its business in each jurisdiction in which
qualification is required, except where the failure to

                                   Exhibit A-1



so qualify would not have a Material Adverse Effect.

         2.       The execution and delivery by the Borrower of the Loan
Documents and the performance by the Borrower of its obligations thereunder have
been duly authorized by proper corporate proceedings on the part of the Borrower
and will not:

                  (a)      require any consent of the Borrower's shareholders;

                  (b)      violate (i) any law, rule, regulation, order, writ,
         judgment, injunction, decree or award binding on the Borrower or (ii)
         the Borrower's restated articles of incorporation, or bylaws, or (iii)
         the provisions of any indenture, instrument or agreement to which the
         Borrower is a party or is subject, or by which it, or its Property, is
         bound, or conflict with or constitute a default thereunder; or

                  (c)      result in, or require, the creation or imposition of
         any Lien in, of, or on the Property of the Borrower pursuant to the
         terms of any indenture, instrument or agreement binding upon the
         Borrower.

         3.       The Loan Documents have been duly executed and delivered by
the Borrower and constitute the legal, valid and binding obligations of the
Borrower enforceable against the Borrower in accordance with their terms except
to the extent the enforcement thereof may be limited by bankruptcy, insolvency
or similar laws affecting the enforcement of creditors' rights generally and
subject also to the availability of equitable remedies if equitable remedies are
sought.

         4.       Except as set forth in the Borrower's Annual Report on Form
10-K for the fiscal year ended December 31, 2001, the Borrower's Quarterly
reports on Form 10-Q for the quarters ended March 31, 2002, June 30, 2002, and
September 30, 2002, and in Schedule 5.7 to the Agreement, there is no
litigation, arbitration, governmental investigation, proceeding or inquiry
pending or, to the best of our knowledge after due inquiry, threatened against
the Borrower which, if adversely determined, could reasonably be expected to
have a Material Adverse Effect.

         5.       No order, consent, adjudication, approval, license,
authorization, or validation of, or filing, recording or registration with, or
exemption by, or other action in respect of any governmental or public body or
authority, or any subdivision thereof which has not been obtained by the
Borrower is required to be obtained by the Borrower in connection with the
execution and delivery of the Loan Documents, the borrowings under the
Agreement, the payment and performance by the Borrower of the Obligations, or
the legality, validity, binding effect or enforceability of any of the Loan
Documents.

         This opinion is subject to and qualified in all respects by the
following:

         1.       This opinion is limited to federal law and the laws of New
Mexico as in effect on the date hereof, and we disclaim any responsibility to
inform you of any changes after the date

                                   Exhibit A-2



hereof. We express no opinion as to (a) any matter that may be governed by the
laws of any other jurisdiction; (b) state and federal securities, tax, and ERISA
laws, rules, and regulations; or (c) potential liability imposed by any of the
foregoing laws with respect to the transactions contemplated by the Agreement.

         2.       We express no opinion not expressly stated herein, and no
further or other opinion shall be implied.

          This opinion is being delivered solely in connection with the closing
under the Agreement that is being consummated on the date hereof. The opinions
expressed herein are based upon the laws mentioned above in effect on the date
hereof, and we assume no obligation to revise or supplement this letter to take
into account any event, action, interpretation, change of circumstance, change
of law or other matters coming to our attention after the date hereof.

          This opinion may be relied upon by the Agent, the Lenders, and their
participants, assignees and other transferees.

                                Very truly yours,

                                   Exhibit A-3



                                    EXHIBIT B

                          FORM OF ASSIGNMENT AGREEMENT

         This Assignment Agreement (this "Assignment Agreement") between
_______________________________ (the "Assignor") and _________________________
(the "Assignee") is dated as of ___________________, 20___. The parties hereto
agree as follows:

         1.       PRELIMINARY STATEMENT. The Assignor is a party to a Credit
Agreement (which, as it may be amended, modified, renewed or extended from time
to time is herein called the "Credit Agreement") described in Item 1 of Schedule
1 attached hereto ("Schedule 1"). Capitalized terms used herein and not
otherwise defined herein shall have the meanings attributed to them in the
Credit Agreement.

         2.       ASSIGNMENT AND ASSUMPTION. The Assignor hereby sells and
assigns to the Assignee, and the Assignee hereby purchases and assumes from the
Assignor, an interest in and to the Assignor's rights and obligations under the
Credit Agreement and the other Loan Documents, such that after giving effect to
such assignment the Assignee shall have purchased pursuant to this Assignment
Agreement the percentage interest specified in Item 3 of Schedule 1 of all
outstanding rights and obligations under the Credit Agreement and the other Loan
Documents relating to the facilities listed in Item 3 of Schedule 1. The
aggregate Commitment (or Loans, if the applicable Commitment has been
terminated) purchased by the Assignee hereunder is set forth in Item 4 of
Schedule 1.

         3.       EFFECTIVE DATE. The effective date of this Assignment
Agreement (the "Effective Date") shall be the later of the date specified in
Item 5 of Schedule 1 or two Business Days (or such shorter period agreed to by
the Agent) after this Assignment Agreement, together with any consents required
under the Credit Agreement, are delivered to the Agent. In no event will the
Effective Date occur if the payments required to be made by the Assignee to the
Assignor on the Effective Date are not made on the proposed Effective Date.

         4.       PAYMENT OBLIGATIONS. In consideration for the sale and
assignment of Loans hereunder, the Assignee shall pay the Assignor, on the
Effective Date, the amount agreed to by the Assignor and the Assignee. On and
after the Effective Date, the Assignee shall be entitled to receive from the
Agent all payments of principal, interest and fees with respect to the interest
assigned hereby. The Assignee will promptly remit to the Assignor any interest
on Loans and fees received from the Agent which relate to the portion of the
Commitment or Loans assigned to the Assignee hereunder for periods prior to the
Effective Date and not previously paid by the Assignee to the Assignor. In the
event that either party hereto receives any payment to which the other party
hereto is entitled under this Assignment Agreement, then the party receiving
such amount shall promptly remit it to the other party hereto.

         5.       RECORDATION FEE. The Assignor and Assignee each agree to pay
one-half of the recordation fee required to be paid to the Agent in connection
with this Assignment Agreement unless otherwise specified in Item 6 of Schedule
1.

         6.       REPRESENTATIONS OF THE ASSIGNOR; LIMITATIONS ON THE ASSIGNOR'S
