person's interest to the Borrower, whether such right to payment is or is not
already earned by performance, and howsoever such right to payment may be
evidenced, together with all other rights and interests (including all Liens)
which the Borrower may at any time have by law or agreement against any account
debtor or other obligor obligated to make any such payment or against any

person requesting an Advance was not in fact authorized to do so. Any request
for an Advance, whether written or telephonic, shall be deemed to be a
representation by the Borrower that the conditions set forth in Section 4.2 have
been satisfied as of the time of the request.

         (b) DISBURSEMENT. Upon fulfillment of the applicable conditions set
forth in Article IV, the Lender shall disburse the proceeds of the requested

Rules and L/C Rules then in effect, costs of issuing or maintaining any Advance
or Letter of Credit and amounts received or receivable under this Agreement or

         (e) "Rule Change" means any change in any Capital Adequacy Rule or L/C
Rule occurring after the date of this Agreement, or any change in the

Rules or any increases in the capital that the Lender is required to maintain to
the extent that the increases are required due to a regulatory authority's
assessment of that Lender's financial condition.

                  The initial notice sent by the Lender shall be sent as
promptly as practicable after the Lender learns that its Return has been
reduced, shall include a demand for payment of the amount necessary to restore
the Lender's Return for the quarter in which the notice is sent, and shall state
in reasonable detail the cause for the reduction in its Return and its
calculation of the amount of such reduction. Thereafter, the Lender may send a

reduced Return for that quarter and including a demand for payment of the amount
necessary to restore its Return for that quarter. The Lender's calculation in
any such notice shall be conclusive and binding absent demonstrable error.

         Lender and the Issuer. The terms and conditions set forth in each such
         L/C Application shall supplement the terms and conditions hereof, but
         if the terms of any such L/C Application and the terms of this
         Agreement are inconsistent, the terms hereof shall control.

         (b) No Letter of Credit shall be issued with an expiry date later than
the Termination Date in effect as of the date of issuance.

         (c) Any request to cause an Issuer to issue a Letter of Credit shall be
deemed to be a representation by the Borrower that the conditions set forth in
Section 4.2 have been satisfied as of the date of the request.

         Section 2.5 Special Account. If the Credit Facility is terminated for
any reason while any Letter of Credit is outstanding, the Borrower shall
thereupon pay the Lender in immediately available funds for deposit in the
Special Account an amount equal to the L/C Amount. The Special Account shall be

institution acceptable to the Lender. Any interest earned on amounts deposited
in the Special Account shall be credited to the Special Account. The Lender may

<PAGE>

repayable in accordance with and be treated in all other respects as a Revolving
Advance hereunder.

         (c) If a draft is submitted under a Letter of Credit when the Borrower
is unable, because a Default Period exists or for any other reason, to obtain a
Revolving Advance to pay the Obligation of Reimbursement, the Borrower shall pay
to the Lender on demand and in immediately available funds, the amount of the
Obligation of Reimbursement together with interest, accrued from the date of the
draft until payment in full at the Default Rate. Notwithstanding the Borrower's
inability to obtain a Revolving Advance for any reason, the Lender is
irrevocably authorized, in its sole discretion, to make a Revolving Advance in
an amount sufficient to discharge the Obligation of Reimbursement and all
accrued but unpaid interest thereon.

         (d) The Borrower's obligation to pay any Revolving Advance made under
this Section 2.6, shall be evidenced by the Revolving Note and shall bear
interest as provided in Section 2.8.

         Section 2.7 Obligations Absolute. The Borrower's obligations arising
under Section 2.6 shall be absolute, unconditional and irrevocable, and shall be
paid strictly in accordance with the terms of Section 2.6, under all
circumstances whatsoever, including (without limitation) the following
circumstances:

         (a) any lack of validity or enforceability of any Letter of Credit or
any other agreement or instrument relating to any Letter of Credit (collectively
the "Related Documents");

         (b) any amendment or waiver of or any consent to departure from all or
any of the Related Documents;

         (c) the existence of any claim, setoff, defense or other right which
the Borrower may have at any time, against any beneficiary or any transferee of
any Letter of Credit (or any persons or entities for whom any such beneficiary
or any such transferee may be acting), or other person or entity, whether in
connection with this Agreement, the transactions contemplated herein or in the
Related Documents or any unrelated transactions;

         (d) any statement or any other document presented under any Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect
or any statement therein being untrue or inaccurate in any respect whatsoever;

         (e) payment by or on behalf of the Issuer under any Letter of Credit
against presentation of a draft or certificate which does not strictly comply
with the terms of such Letter of Credit; or

         (f) any other circumstance or happening whatsoever, whether or not
similar to any of the foregoing.

         Section 2.8 Interest; Minimum Interest Charge; Default Interest;
Clearance Days; Participations; Usury.

         (a) INTEREST. Except as set forth in Section 2.8(c) and Section 2.8(f),
the outstanding principal balance of the Note shall bear interest at the
Floating Rate.

                                      -15-
<PAGE>

         (b) MINIMUM INTEREST CHARGE. Notwithstanding the interest payable
pursuant to Subsection (a), the Borrower shall pay to the Lender interest of not
less than $37,500 per quarter (the "Minimum Interest Charge") during the term of
this Agreement, and the Borrower shall pay any deficiency between (i) the
Minimum Interest Charge and (ii) the sum of the amount of interest otherwise
calculated under Section 2.8(a) of this Agreement, Section 2.8(a) of the
Metretek Credit and Security Agreement and Section 2.5(a) of the Southern Flow
Credit and Security Agreement; on the first day of each quarter and on the
Termination Date. The Borrower will be given full credit on a dollar for dollar
basis against the Minimum Interest Charge payable hereunder to the extent such
amount is paid to the Lender pursuant to the Metretek Credit and Security
Agreement or the Southern Flow Credit and Security Agreement.

         (c) DEFAULT INTEREST RATE. Upon notice to the Borrower from the Lender
from time to time, the principal of the Advances outstanding from time to time
shall bear interest at the Default Rate, effective as of the first day of the
month during which any Default Period begins through the last day of such
Default Period. The Lender's election to charge the Default Rate shall be in its
sole discretion and shall not be a waiver of any of its rights and remedies. The
Lender's election to charge interest at the Default Rate for less than the
entire period during which the Default Rate may be charged shall not be a waiver
of its right to later charge the Default Rate for the entire such period.

         (d) CLEARANCE DAYS. Notwithstanding Section 2.11(b)(ii), interest at
the interest rate applicable under this Section 2.8 shall accrue on the amount
of all payments (even if in the form of immediately available federal funds) for
one (1) day(s) for clearance.

         (e) PARTICIPATIONS. If any Person shall acquire a participation in the
Advances or the Obligation of Reimbursement, the Borrower shall be obligated to
the Lender to pay the full amount of all interest calculated under this Section
2.8, along with all other fees, charges and other amounts due under this
Agreement, regardless if such Person elects to accept interest with respect to
its participation at a lower rate than that calculated under this Section 2.8,
or otherwise elects to accept less than its prorata share of such fees, charges
and other amounts due under this Agreement.

         (f) USURY. In any event no rate change shall be put into effect which
would result in a rate greater than the highest rate permitted by law.
Notwithstanding anything to the contrary contained in any Loan Document, all
agreements which either now are or which shall become agreements between the
Borrower and the Lender are hereby limited so that in no contingency or event
whatsoever shall the total liability for payments in the nature of interest,
additional interest and other charges exceed the applicable limits imposed by
any applicable usury laws. If any payments in the nature of interest, additional
interest and other charges made under any Loan Document are held to be in excess
of the limits imposed by any applicable usury laws, it is agreed that any such
amount held to be in excess shall be considered payment of principal hereunder,
and the indebtedness evidenced hereby shall be reduced by such amount so that
the total liability for payments in the nature of interest, additional interest
and other charges shall not exceed the applicable limits imposed by any
applicable usury laws, in compliance with the desires of the Borrower and the
Lender. This provision shall never be superseded or waived and shall control
every other provision of the Loan Documents and all agreements between the
Borrower and the Lender, or their successors and assigns.

         Section 2.9 Fees.

         (a) RESTRUCTURE FEE. The Borrower shall pay the Lender a fully earned
and non-refundable restructure fee of $7,500, due and payable upon the execution
of this Agreement. The Borrower will be given full credit on a dollar for dollar
basis against the restructure fee payable hereunder to the extent such amount is
paid to the Lender pursuant to the Metretek Credit and Security Agreement or the
Southern Flow Credit and Security Agreement.

         (b) UNUSED LINE FEE. For the purposes of this Section 2.9, "Unused
Amount" means the Maximum Line reduced by (A) outstanding Revolving Advances,
(B) the L/C Amount, (C) outstanding Metretek Revolving Advances, (D) the
Metretek L/C Amount, and (E) outstanding Southern Flow Revolving Advances. The
Borrower agrees to pay to the Lender an unused line fee at the rate of one
quarter of one percent (.25%) per annum on the average daily Unused Amount from
the date of this Agreement to and including the Termination Date, due and
payable monthly in arrears on the first day of the month and on the Termination
Date. The Borrower will be given full credit on a dollar for dollar basis
against the unused line fee payable hereunder to the extent such amount is paid
to the Lender pursuant to the Metretek Credit and Security Agreement or the
Southern Flow Credit and Security Agreement.

         (c) FACILITY FEE. The Borrower agrees to pay to the Lender an annual
facility fee at the rate of one half of one percent (.50%) of the Maximum Line,
which facility fee shall be due and payable annually on September 1st. The
Borrower will be given full credit on a dollar for dollar basis against the
facility fee payable hereunder to the extent such amount is paid to the Lender
pursuant to the Metretek Credit and Security Agreement or the Southern Flow
Credit and Security Agreement.

         (d) AUDIT FEES. The Borrower shall pay the Lender, on demand, audit
fees in connection with any audits or inspections conducted by the Lender of any
Collateral or the Borrower's operations or business at the rates established
from time to time by the Lender as its audit fees (which fees are currently $90
per hour per auditor), together with all actual out-of-pocket costs and expenses
incurred in conducting any such audit or inspection.

         (e) LETTER OF CREDIT FEES. The Borrower shall pay to the Lender a fee
with respect to each Letter of Credit, if any, accruing on a daily basis and
computed at the annual rate of two percent (2.0%) of the aggregate amount that
may then be drawn on under it assuming compliance with all conditions for
drawing (the "Aggregate Face Amount"), from and including the date of issuance
of such Letter of Credit until such date as such Letter of Credit shall
terminate by its terms or be returned to the Lender, due and payable monthly in
arrears on the first day of each month and on the Termination Date; provided,
however, that during Default Periods, in the Lender's sole discretion and
without waiving any of its other rights and remedies, such fee shall increase to
five percent (5.0%) of the Aggregate Face Amount. The foregoing fee shall be in
addition to any and all fees, commissions and charges of the Issuer with respect
to or in connection with such Letter of Credit.

         (f) LETTER OF CREDIT ADMINISTRATIVE FEES. The Borrower shall pay to the
Lender, on written demand, the administrative fees charged by the Issuer in
connection with the honoring of drafts under any Letter of Credit, amendments
thereto, transfers thereof and all other activity

                                      -17-
<PAGE>

with respect to the Letters of Credit at the then-current rates published by the
Issuer for such services rendered on behalf of customers of the Issuer
generally.

         (g) TERMINATION AND LINE REDUCTION FEES. If the Credit Facility is
terminated (i) by the Lender during a Default Period that begins before a
Maturity Date, (ii) by the Borrower (A) as of a date other than a Maturity Date
or (B) as of a Maturity Date but without the Lender having received written
notice of such termination at least 90 days before such Maturity Date, or if the
Borrower reduces the Maximum Line, the Borrower shall pay to the Lender a fee in
an amount equal to a percentage of the Maximum Line (or the reduction of the
Maximum Line, as the case may be) as follows: (A) two percent (2.0%) if the
termination or reduction occurs on or before September 30, 2004; and (B) one
percent (1.0%) if the termination or reduction occurs after September 30, 2004.
The Borrower will be given full credit on a dollar for dollar basis against the
fee payable hereunder to the extent such amount is paid to the Lender pursuant
to the Metretek Credit and Security Agreement or the Southern Flow Credit and
Security Agreement.

         (h) WAIVER OF TERMINATION FEE. The Borrower will not be required to pay
the termination fee otherwise due under Section 2.9(g) if (i) such termination
or prepayment is made because of refinancing by an affiliate of the Lender or
(ii) the Credit Facility is refinanced within 90 days after a request by the
Lender for compensation under Section 2.3.

         (i) OTHER FEES. The Lender may from time to time charge additional fees
for Advances made in excess of the Borrowing Base, for late delivery of reports,
in lieu of imposing interest at the Default Rate, and (during a Default Period)
for other reasons.

         Section 2.10 Time for Interest Payments; Payment on Non-Banking Days;
Computation of Interest and Fees.

         (a) TIME FOR INTEREST PAYMENTS. Interest shall be due and payable in
arrears on the first day of each month and on the Termination Date.

         (b) PAYMENT ON NON-BANKING DAYS. Whenever any payment to be made
hereunder shall be stated to be due on a day which is not a Banking Day, such
payment may be made on the next succeeding Banking Day, and such extension of
time shall in such case be included in the computation of interest on the
Advances or the fees hereunder, as the case may be.

         (c) COMPUTATION OF INTEREST AND FEES. Interest accruing on the
outstanding principal balance of the Advances and fees hereunder outstanding
from time to time shall be computed on the basis of actual number of days
elapsed in a year of 360 days.

         Section 2.11 Lockbox and Collateral Account; Application of Payments.

         (a) LOCKBOX AND COLLATERAL ACCOUNT.

                  (i)      The Borrower shall instruct all account debtors to
         pay all Accounts directly to the Lockbox. If, notwithstanding such
         instructions, the Borrower receives any payments on Accounts, the
         Borrower shall deposit such payments into the Collateral Account. The
         Borrower shall also deposit all other cash proceeds of Collateral
         directly into the Collateral Account. Until so deposited, the Borrower
         shall hold all such

                                      -18-
<PAGE>

         payments and cash proceeds in trust for and as the property of the
         Lender and shall not commingle such property with any of its other
         funds or property. Amounts deposited in the Collateral Account shall
         not bear interest. All deposits in the Collateral Account shall
         constitute proceeds of Collateral and shall not constitute payment of
         the Obligations.

                  (ii)     All items deposited in the Collateral Account shall
         be subject to final payment. If any such item is returned uncollected,
         the Borrower will immediately pay the Lender, or, for items deposited
         in the Collateral Account, the bank maintaining such account, the
         amount of that item, or such bank at its discretion may charge any
         uncollected item to the Borrower's commercial account or other account.
         The Borrower shall be liable as an endorser on all items deposited in
         the Collateral Account, whether or not in fact endorsed by the
         Borrower.

         (b) APPLICATION OF PAYMENTS.

                  (i)      The Borrower may, from time to time, in accordance
         with the Lockbox and Collection Account Agreement, cause funds in the
         Collateral Account to be transferred to the Lender's general account
         for payment of the Obligations. Except as provided in the preceding
         sentence, amounts deposited in the Collateral Account shall not be
         subject to withdrawal by the Borrower, except after full payment and
         discharge of all Obligations.

                  (ii)     All payments to the Lender shall be made in
         immediately available funds and shall be applied to the Obligations
         upon receipt by the Lender. Funds received from the Collateral Account
         shall be deemed to be immediately available. The Lender may hold all
         payments not constituting immediately available funds for three (3)
         additional days before applying them to the Obligations.

         Section 2.12 Voluntary Prepayment; Reduction of the Maximum Line;
Termination of the Credit Facility by the Borrower. Except as otherwise provided
herein, the Borrower may prepay the Advances in whole at any time or from time
to time in part. The Borrower may terminate the Credit Facility or reduce the
Maximum Line at any time if it (i) gives the Lender at least 30 days' prior
written notice and (ii) pays the Lender termination or Maximum Line reduction
fees in accordance with Section 2.9(g). Any reduction in the Maximum Line must
be in an amount of not less than $100,000 or an integral multiple thereof. If
the Borrower reduces the Maximum Line to zero, all Obligations shall be
immediately due and payable. Subject to termination of the Credit Facility and
payment and performance of all Obligations, the Lender shall, at the Borrower's
expense, release or terminate the Security Interest and the Security Documents
to which the Borrower is entitled by law.

         Section 2.13 Mandatory Prepayment. Without notice or demand, if the sum
of the outstanding principal balance of the Revolving Advances plus the L/C
Amount shall at any time exceed the Borrowing Base, the Borrower shall (i)
first, immediately prepay the Revolving Advances to the extent necessary to
eliminate such excess; and (ii) if prepayment in full of the Revolving Advances
is insufficient to eliminate such excess, pay to the Lender in immediately
available funds for deposit in the Special Account an amount equal to the
remaining excess. Any payment received by the Lender under this Section 2.13 or
under Section 2.12 may be applied to

                                      -19-
<PAGE>

the Obligations, in such order and in such amounts as the Lender, in its
discretion, may from time to time determine.

         Section 2.14 Revolving Advances to Pay Obligations. Notwithstanding
anything in Section 2.1, the Lender may, in its discretion at any time or from
time to time, without the Borrower's request and even if the conditions set
forth in Section 4.2 would not be satisfied, make a Revolving Advance in an
amount equal to the portion of the Obligations from time to time due and
payable.

         Section 2.15 Use of Proceeds. The Borrower shall use the proceeds of
Advances and each Letter of Credit for ordinary working capital purposes and to
provide advances to Corporate Guarantors in accordance with Section 6.27.

         Section 2.16 Liability Records. The Lender may maintain from time to
time, at its discretion, records as to the Obligations. All entries made on any
such record shall be presumed correct until the Borrower establishes the
contrary. Upon the Lender's demand, the Borrower will admit and certify in
writing the exact principal balance of the Obligations that the Borrower then
asserts to be outstanding. Any billing statement or accounting rendered by the
Lender shall be conclusive and fully binding on the Borrower unless the Borrower
gives the Lender specific written notice of exception within 30 days after
receipt.

                                   ARTICLE III

                      SECURITY INTEREST; OCCUPANCY; SETOFF

         Section 3.1 Grant of Security Interest. The Borrower hereby pledges,
assigns and grants to the Lender a lien and security interest (collectively
referred to as the "Security Interest") in the Collateral, as security for the
payment and performance of the Obligations. Upon request by the Lender, the
Borrower will grant the Lender a security interest in all commercial tort claims
it may have against any Person.

         Section 3.2 Notification of Account Debtors and Other Obligors. The
Lender may at any time (whether or not a Default Period then exists) notify any
account debtor or other person obligated to pay the amount due that such right
to payment has been assigned or transferred to the Lender for security and shall
be paid directly to the Lender. The Borrower will join in giving such notice if
the Lender so requests. At any time after the Borrower or the Lender gives such
notice to an account debtor or other obligor, the Lender may, but need not, in
the Lender's name or in the Borrower's name, (a) demand, sue for, collect or
receive any money or property at any time payable or receivable on account of,
or securing, any such right to payment, or grant any extension to, make any
compromise or settlement with or otherwise agree to waive, modify, amend or
change the obligations (including collateral obligations) of any such account
debtor or other obligor; and (b) as the Borrower's agent and attorney-in-fact,
notify the United States Postal Service to change the address for delivery of
the Borrower's mail to any address designated by the Lender, otherwise intercept
the Borrower's mail, and receive, open and dispose of the Borrower's mail,
applying all Collateral as permitted under this Agreement and holding all other
mail for the Borrower's account or forwarding such mail to the Borrower's last
known address.

                                      -20-
<PAGE>

         Section 3.3 Assignment of Insurance. As additional security for the
payment and performance of the Obligations, the Borrower hereby assigns to the
Lender any and all monies (including proceeds of insurance and refunds of
unearned premiums) due or to become due under, and all other rights of the
Borrower with respect to, any and all policies of insurance now or at any time
hereafter covering the Collateral or any evidence thereof or any business
records or valuable papers pertaining thereto, and the Borrower hereby directs
the issuer of any such policy to pay all such monies directly to the Lender. At
any time, whether or not a Default Period then exists, the Lender may (but need
not), in the Lender's name or in the Borrower's name, execute and deliver proof
of claim, receive all such monies, endorse checks and other instruments
representing payment of such monies, and adjust, litigate, compromise or release
any claim against the issuer of any such policy.

         Section 3.4 Occupancy.

         (a) The Borrower hereby irrevocably grants to the Lender the right to
take exclusive possession of the Premises at any time during a Default Period.

         (b) The Lender may use the Premises only to hold, process, manufacture,
sell, use, store, liquidate, realize upon or otherwise dispose of goods that are
Collateral and for other purposes that the Lender may in good faith deem to be
related or incidental purposes.

         (c) The Lender's right to hold the Premises shall cease and terminate
upon the earlier of (i) payment in full and discharge of all Obligations and
termination of the Credit Facility, and (ii) final sale or disposition of all
goods constituting Collateral and delivery of all such goods to purchasers.

         (d) The Lender shall not be obligated to pay or account for any rent or
other compensation for the possession, occupancy or use of any of the Premises;
provided, however, that if the Lender does pay or account for any rent or other
compensation for the possession, occupancy or use of any of the Premises, the
Borrower shall reimburse the Lender promptly for the full amount thereof. In
addition, the Borrower will pay, or reimburse the Lender for, all taxes, fees,
duties, imposts, charges and expenses at any time incurred by or imposed upon
the Lender by reason of the execution, delivery, existence, recordation,
performance or enforcement of this Agreement or the provisions of this Section
3.4.

         Section 3.5 License. Without limiting the generality of any other
Security Document, the Borrower hereby grants to the Lender a non-exclusive,
worldwide and royalty-free license to use or otherwise exploit all Intellectual
Property Rights of the Borrower for the purpose of: (a) completing the
manufacture of any in-process materials during any Default Period so that such
materials become saleable Inventory, all in accordance with the same quality
standards previously adopted by the Borrower for its own manufacturing and
subject to the Borrower's reasonable exercise of quality control; and (b)
selling, leasing or otherwise disposing of any or all Collateral during any
Default Period.

         Section 3.6 Financing Statement. The Borrower authorizes the Lender to
file from time to time where permitted by law, such financing statements against
collateral described as "all personal property" or describing specific items of
collateral including commercial tort claims

                                      -21-
<PAGE>

as the Lender deems necessary or useful to perfect the Security Interest. All
financing statements filed before the date hereof to perfect the Security
Interest were authorized by the Borrower and are hereby re-authorized. A carbon,
photographic or other reproduction of this Agreement or of any financing
statements signed by the Borrower is sufficient as a financing statement and may
be filed as a financing statement in any state to perfect the security interests
granted hereby. For this purpose, the following information is set forth:

                  Denver, Colorado 80274

         Section 3.7 Setoff. The Lender may at any time or from time to time
after a Default or an Event of Default has occurred and is continuing, at its
sole discretion and without demand and without notice to anyone, setoff any
liability owed to the Borrower by the Lender, whether or not due, against any
Obligation, whether or not due. In addition, each other Person holding a
participating interest in any Obligations shall have the right to appropriate or
setoff any deposit or other liability then owed by such Person to the Borrower,
whether or not due, and apply the same to the payment of said participating
interest, as fully as if such Person had lent directly to the Borrower the
amount of such participating interest.

         Section 3.8 Collateral. This Agreement does not contemplate a sale of
accounts, contract rights or chattel paper, and, as provided by law, the
Borrower is entitled to any surplus and shall remain liable for any deficiency.
The Lender's duty of care with respect to Collateral in its possession (as
imposed by law) shall be deemed fulfilled if it exercises reasonable care in
physically keeping such Collateral, or in the case of Collateral in the custody
or possession of a bailee or other third person, exercises reasonable care in
the selection of the bailee or other third person, and the Lender need not
otherwise preserve, protect, insure or care for any Collateral. The Lender shall
not be obligated to preserve any rights the Borrower may have against prior
parties, to realize on the Collateral at all or in any particular manner or
order or to apply any cash proceeds of the Collateral in any particular order of
application. The Lender has no obligation to clean-up or otherwise prepare the
Collateral for sale. The Borrower waives any right it may have to require the
Lender to pursue any third person for any of the Obligations.

         The Borrower represents and warrants to the Lender as follows:

         Section 5.1 Existence and Power; Name; Chief Executive Office;
Inventory and Equipment Locations; Federal Employer Identification Number and
Organizational Identification Number. The Borrower is a corporation, duly
organized, validly existing and in good standing under the laws of the State of
the jurisdiction of its incorporation and is duly licensed or qualified to
transact business in all jurisdictions where the character of the property owned
or leased or the nature of the business transacted by it makes such licensing or
qualification necessary. The Borrower has all requisite power and authority to
conduct its business, to own its properties and to execute and deliver, and to
perform all of its obligations under, the Loan Documents. During its existence,
the Borrower has done business solely under the names set forth in Schedule 5.1.
The Borrower's chief executive office and principal place of business is located
at the address set forth in Schedule 5.1, and all of the Borrower's records
relating to its business or the Collateral

                                      -25-
<PAGE>

are kept at that location. All Inventory and Equipment is located at that
location or at one of the other locations listed in Schedule 5.1. The Borrower's
federal employer identification number and organization identification number
are correctly set forth in Section 3.6.

         Section 5.2 Capitalization. Schedule 5.2 constitutes a correct and
complete list of all ownership interests of the Borrower and rights to acquire
ownership interests including the record holder, number of interests and
percentage interests on a fully diluted basis, and an organizational chart
showing the ownership structure of all Subsidiaries of the Borrower.

         Section 5.3 Authorization of Borrowing; No Conflict as to Law or
Agreements. The execution, delivery and performance by the Borrower of the Loan
Documents and the borrowings from time to time hereunder have been duly
authorized by all necessary corporate action and do not and will not (i) require
any consent or approval of the Borrower's Owners; (ii) require any
authorization, consent or approval by, or registration, declaration or filing
with, or notice to, any governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, or any third party, except such
authorization, consent, approval, registration, declaration, filing or notice as
has been obtained, accomplished or given prior to the date hereof; (iii) violate
any provision of any law, rule or regulation (including Regulation X of the
Board of Governors of the Federal Reserve System) or of any order, writ,
injunction or decree presently in effect having applicability to the Borrower or
of the Borrower's Constituent Documents; (iv) result in a breach of or
constitute a default under any indenture or loan or credit agreement or any
other material agreement, lease or instrument to which the Borrower is a party

Interest) upon or with respect to any of the properties now owned or hereafter
acquired by the Borrower.

         Section 5.4 Legal Agreements. This Agreement constitutes and, upon due
execution by the Borrower, the other Loan Documents will constitute the legal,
valid and binding obligations of the Borrower, enforceable against the Borrower
in accordance with their respective terms.

         Section 5.5 Subsidiaries. Except as set forth in Schedule 5.5 hereto,
the Borrower has no Subsidiaries.

         Section 5.6 Financial Condition; No Adverse Change. The Borrower has
furnished to the Lender its audited financial statements for its fiscal year
ended December 31, 2002 and unaudited financial statements for the
fiscal-year-to-date period ended July 31, 2003, and those statements fairly
present the Borrower's financial condition on the dates thereof and the results
of its operations and cash flows for the periods then ended and were prepared in
accordance with GAAP. For purposes of this Agreement, the Lender agrees that the
audited consolidated financial statements of Parent and its Subsidiaries,
including Borrower, and the consolidating financial statements of Borrower
included therein, shall constitute the "audited" financial statements of
Borrower hereunder. Since the date of the most recent financial statements,
there has been no change in the Borrower's business, properties or condition
(financial or otherwise) which has had a Material Adverse Effect.

         Section 5.7 Litigation. There are no actions, suits or proceedings
pending or, to the Borrower's knowledge, threatened against or affecting the
Borrower or any of its Affiliates or the properties of the Borrower or any of
its Affiliates before any court or governmental department, commission, board,

adversely to the Borrower or any of its Affiliates, would have a Material
Adverse Effect, except as set forth on Schedule 5.7.

         Section 5.8 Regulation U. The Borrower is not engaged in the business
of extending credit for the purpose of purchasing or carrying margin stock
(within the meaning of Regulation U of the Board of Governors of the Federal
Reserve System), and no part of the proceeds of any Advance will be used to
purchase or carry any margin stock or to extend credit to others for the purpose
of purchasing or carrying any margin stock.

         Section 5.9 Taxes. The Borrower and its Affiliates have paid or caused
to be paid to the proper authorities when due all federal, state and local taxes
required to be withheld by each of them, except to the extent of any taxes that
are being contested in good faith by appropriate proceedings and for which
proper reserves have been made in accordance with GAAP. Except as set forth in
the foregoing proviso, the Borrower and its Affiliates have filed all federal,
state and local tax returns which to the knowledge of the Officers of the
Borrower or any Affiliate, as the case may be, are required to be filed, and the
Borrower and its Affiliates have paid or caused to be paid to the respective
taxing authorities all taxes as shown on said returns or on any assessment
received by any of them to the extent such taxes have become due.

         Section 5.10 Titles and Liens. The Borrower has good and absolute title

financing statement naming the Borrower as debtor is on file in any office
except to perfect only Permitted Liens.

         (a) OWNED INTELLECTUAL PROPERTY. Schedule 5.11 is a complete list of
all patents, applications for patents, trademarks, applications to register
trademarks, service marks, applications to register service marks, mask works,
trade dress and copyrights for which the Borrower is the owner of record (the

Borrower owns the Owned Intellectual Property free and clear of all restrictions
(including covenants not to sue a third party), court orders, injunctions,
decrees, writs or Liens, whether by written agreement or otherwise, (ii) no
Person other than the Borrower owns or has been granted any right in the Owned
Intellectual Property, (iii) all Owned Intellectual Property is valid,
subsisting and enforceable and (iv) the Borrower has taken all commercially
reasonable action necessary to maintain and protect the Owned Intellectual
Property.

         (b) AGREEMENTS WITH EMPLOYEES AND CONTRACTORS. The Borrower has entered
into a legally enforceable agreement with each of its employees and
subcontractors obligating each such Person to assign to the Borrower, without
any additional compensation, any Intellectual Property Rights created,
discovered or invented by such Person in the course of such Person's employment
or engagement with the Borrower (except to the extent prohibited by law), and
further requiring such Person to cooperate with the Borrower, without any
additional

                                      -27-
<PAGE>

compensation, in connection with securing and enforcing any Intellectual
Property Rights therein; provided, however, that the foregoing shall not apply
with respect to employees and subcontractors whose job descriptions are of the
type such that no such assignments are reasonably foreseeable.

         (c) INTELLECTUAL PROPERTY RIGHTS LICENSED FROM OTHERS. Schedule 5.11 is
a complete list of all agreements under which the Borrower has licensed
Intellectual Property Rights from another Person ("Licensed Intellectual
Property") other than readily available, non-negotiated licenses of computer
software and other intellectual property used solely for performing accounting,
word processing and similar administrative tasks ("Off-the-shelf Software") and
a summary of any ongoing payments the Borrower is obligated to make with respect
thereto. Except as disclosed on Schedule 5.11 and in written agreements copies
of which have been given to the Lender, the Borrower's licenses to use the
Licensed Intellectual Property are free and clear of all restrictions, Liens,
court orders, injunctions, decrees, or writs, whether by written agreement or
otherwise. Except as disclosed on Schedule 5.11, the Borrower is not obligated
or under any liability whatsoever to make any payments of a material nature by
way of royalties, fees or otherwise to any owner of, licensor of, or other
claimant to, any Intellectual Property Rights.

         (d) OTHER INTELLECTUAL PROPERTY NEEDED FOR BUSINESS. Except for
Off-the-shelf Software and as disclosed on Schedule 5.11, the Owned Intellectual
Property and the Licensed Intellectual Property constitute all Intellectual
Property Rights used or necessary to conduct the Borrower's business as it is
presently conducted or as the Borrower reasonably foresees conducting it.

         (e) INFRINGEMENT. Except as disclosed on Schedule 5.11, the Borrower
has no knowledge of, and has not received any written claim or notice alleging,
any Infringement of another Person's Intellectual Property Rights (including any
written claim that the Borrower must license or refrain from using the
Intellectual Property Rights of any third party) nor, to the Borrower's
knowledge, is there any threatened claim or any reasonable basis for any such
claim.

         Section 5.12 Plans. Except as disclosed to the Lender in writing prior

or has maintained any Pension Plan, (ii) contributes or has contributed to any
Multiemployer Plan or (iii) provides or has provided post-retirement medical or
insurance benefits with respect to employees or former employees (other than
benefits required under Section 601 of ERISA, Section 4980B of the IRC or
applicable state law). Neither the Borrower nor any ERISA Affiliate has received
any notice or has any knowledge to the effect that it is not in full compliance
with any of the requirements of ERISA, the IRC or applicable state law with
respect to any Plan. No Reportable Event exists in connection with any Pension
Plan. Each Plan which is intended to qualify under the IRC is so qualified, and
no fact or circumstance exists which may have an adverse effect on the Plan's
tax-qualified status. Neither the Borrower nor any ERISA Affiliate has (i) any
accumulated funding deficiency (as defined in Section 302 of ERISA and Section
412 of the IRC) under any Plan, whether or not waived, (ii) any liability under
Section 4201 or 4243 of ERISA for any withdrawal, partial withdrawal,
reorganization or other event under any Multiemployer Plan or (iii) any
liability or knowledge of any facts or circumstances which could result in any
liability to the Pension Benefit Guaranty Corporation, the Internal Revenue
Service, the Department of

                                      -28-

Labor or any participant in connection with any Plan (other than routine claims
for benefits under the Plan).

         Section 5.13 Default. The Borrower is in compliance with all provisions
of all agreements, instruments, decrees and orders to which it is a party or by
which it or its property is bound or affected, the breach or default of which
could have a Material Adverse Effect.

         Section 5.14 Environmental Matters.

         (a) To the Borrower's best knowledge, there are not present in, on or
under the Premises any Hazardous Substances in such form or quantity as to
create any material liability or obligation for either the Borrower or the
Lender under the common law of any jurisdiction or under any Environmental Law,
and no Hazardous Substances have ever been stored, buried, spilled, leaked,
discharged, emitted or released in, on or under the Premises in such a way as to
create any such material liability.

         (b) To the Borrower's best knowledge, the Borrower has not disposed of
Hazardous Substances in such a manner as to create any material liability under
any Environmental Law.

         (c) There are not and there never have been any requests, claims,
notices, investigations, demands, administrative proceedings, hearings or
litigation, relating in any way to the Premises or the Borrower, alleging
material liability under, violation of, or noncompliance with any Environmental

the Borrower's best knowledge, no such matter is threatened or impending.

         (d) To the Borrower's best knowledge, the Borrower's businesses are and
have in the past always been conducted in accordance with all Environmental Laws
and all licenses, permits and other authorizations required pursuant to any
Environmental Law and necessary for the lawful and efficient operation of such
businesses are in the Borrower's possession and are in full force and effect. No
permit required under any Environmental Law is scheduled to expire within 12
months and there is no threat that any such permit will be withdrawn,
terminated, limited or materially changed.

         (e) To the Borrower's best knowledge, the Premises are not and never
have been listed on the National Priorities List, the Comprehensive
Environmental Response, Compensation and Liability Information System or any
similar federal, state or local list, schedule, log, inventory or database.

         (f) The Borrower has delivered to Lender all environmental assessments,
audits, reports, permits, licenses and other documents describing or relating in
any way to the Premises or Borrower's businesses.

         Section 5.15 Submissions to Lender. All financial and other information
provided to the Lender by or on behalf of the Borrower in connection with the
Borrower's request for the credit facilities contemplated hereby is (i) true and
correct in all material respects, (ii) does not omit any material fact necessary
to make such information not misleading and, (iii) as to projections, valuations

         Section 5.16 Financing Statements. The Borrower and each Corporate
Guarantor has authorized the filing of financing statements sufficient when
filed to perfect the Security Interest and the other security interests created
by the Security Documents. When such financing statements are filed in the
offices noted therein, the Lender will have a valid and perfected security
interest in all Collateral which is capable of being perfected by filing
financing statements. None of the Collateral is or will become a fixture on real
estate, unless a sufficient fixture filing is in effect with respect thereto.

         Section 5.17 Rights to Payment. Each right to payment and each
instrument, document, chattel paper and other agreement constituting or
evidencing Collateral is (or, in the case of all future Collateral, will be when
arising or issued) the valid, genuine and legally enforceable obligation,
subject to no defense, setoff or counterclaim, of the account debtor or other
obligor named therein or in the Borrower's records pertaining thereto as being
obligated to pay such obligation.

         Section 5.18 Financial Solvency. Both before and after giving effect to
the transactions contemplated in the Loan Documents, none of the Borrower or its
Affiliates:

Section 101(32) of the United States Bankruptcy Code and Section 2 of the
Uniform Fraudulent Transfer Act;

         (b) has unreasonably small capital or is engaged or about to engage in
a business or a transaction for which any remaining assets of the Borrower or
such Affiliate are unreasonably small;

         (c) by executing, delivering or performing its obligations under the
Loan Documents or other documents to which it is a party or by taking any action
with respect thereto, intends to, nor believes that it will, incur debts beyond
its ability to pay them as they mature;

         (d) by executing, delivering or performing its obligations under the
Loan Documents or other documents to which it is a party or by taking any action
with respect thereto, intends to hinder, delay or defraud either its present or
future creditors; and

         (e) at this time contemplates filing a petition in bankruptcy or for an
arrangement or reorganization or similar proceeding under any law of any
jurisdiction, nor, to the best knowledge of the Borrower, is the subject of any
actual, pending or threatened bankruptcy, insolvency or similar proceedings
under any law of any jurisdiction.

         (t) Any breach, default or event of default by or attributable to any

PowerSecure Guaranty or the PowerSecure Security Agreement, a default under
Section 6.2(a) or Section 6.2(b) of the Metretek Credit and Security Agreement (
a "Metretek Default") shall not constitute an Event of Default under this
Agreement, the PowerSecure Guaranty or the PowerSecure Security Agreement if
within 20 days of the occurrence of the Metretek Default:

         (1)      the Metretek Default is waived by the Lender in writing, or

         (2)      each of the following conditions precedent have been
satisfied, each in form and substance satisfactory to the Lender:

         A.       The Metretek Revolving Note and the Metretek L/C Amount are
paid in full, and all fees and expenses of the Lender payable under the Metretek
Credit and Security Agreement are paid in full.

         B.       The Metretek Credit and Security Agreement is terminated by
Metretek, Incorporated.

         C.       The Southern Flow Term Note is paid in full.

         D.       Neither the Borrower nor Southern Flow Companies, Inc. are in

or any guarantees by the Borrower or Southern Flow Companies, Inc. in favor of
the Lender or any security agreements by and between the Lender and the Borrower
or Southern Flow Companies, Inc.

provided, further, however, that Metretek, Incorporated will remain as a
Guarantor under this Agreement and under the Southern Flow Credit and Security
Agreement.

         Section 7.2 Rights and Remedies. During any Default Period, the Lender
may exercise any or all of the following rights and remedies:

         (a) the Lender may, by notice to the Borrower, declare the Commitment
to be terminated, whereupon the same shall forthwith terminate;

         (b) the Lender may, by notice to the Borrower, declare the Obligations
to be forthwith due and payable, whereupon all Obligations shall become and be
forthwith due and payable, without presentment, notice of dishonor, protest or
further notice of any kind, all of which the Borrower hereby expressly waives;

         (c) the Lender may, without notice to the Borrower and without further
action, apply any and all money owing by the Lender to the Borrower to the
payment of the Obligations;

                                      -43-
<PAGE>

         (d) the Lender may exercise and enforce any and all rights and remedies
available upon default to a secured party under the UCC, including the right to
take possession of Collateral, or any evidence thereof, proceeding without
judicial process or by judicial process (without a prior hearing or notice
thereof, which the Borrower hereby expressly waives) and the right to sell,
lease or otherwise dispose of any or all of the Collateral (with or without
giving any warranties as to the Collateral, title to the Collateral or similar
warranties), and, in connection therewith, the Borrower will on demand assemble
the Collateral and make it available to the Lender at a place to be designated
by the Lender which is reasonably convenient to both parties;

         (e) the Lender may make demand upon the Borrower and, forthwith upon
such demand, the Borrower will pay to the Lender in immediately available funds
for deposit in the Special Account pursuant to Section 2.13 an amount equal to
the aggregate maximum amount available to be drawn under all Letters of Credit
then outstanding, assuming compliance with all conditions for drawing
thereunder;

         (f) the Lender may exercise and enforce its rights and remedies under
the Loan Documents; and

         (g) the Lender may exercise any other rights and remedies available to
it by law or agreement.

Notwithstanding the foregoing, upon the occurrence of an Event of Default
described in Section 7.1(e) or Section 7.1(f), the Obligations shall be
immediately due and payable automatically without presentment, demand, protest
or notice of any kind. If the Lender sells any of the Collateral on credit, the
Obligations will be reduced only to the extent of payments actually received. If
the purchaser fails to pay for the Collateral, the Lender may resell the
Collateral and shall apply any proceeds actually received to the Obligations.

         Section 7.3 Certain Notices. If notice to the Borrower of any intended
disposition of Collateral or any other intended action is required by law in a
particular instance, such notice shall be deemed commercially reasonable if
given (in the manner specified in Section 8.3) at least ten calendar days before
the date of intended disposition or other action.

                                  ARTICLE VIII

                                  MISCELLANEOUS

         Section 8.1 No Waiver; Cumulative Remedies; Compliance with Laws. No
failure or delay by the Lender in exercising any right, power or remedy under
the Loan Documents shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right, power or remedy preclude any other or
further exercise thereof or the exercise of any other right, power or remedy
under the Loan Documents. The remedies provided in the Loan Documents are
cumulative and not exclusive of any remedies provided by law. The Lender may
comply with any applicable state or federal law requirements in connection with
a disposition of the Collateral and such compliance will not be considered
adversely to affect the commercial reasonableness of any sale of the Collateral.

<PAGE>

         Section 8.2 Amendments, Etc. No amendment, modification, termination or
waiver of any provision of any Loan Document or consent to any departure by the
Borrower therefrom or any release of a Security Interest shall be effective
unless the same shall be in writing and signed by the Lender, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. No notice to or demand on the Borrower in any
case shall entitle the Borrower to any other or further notice or demand in
similar or other circumstances.

         Section 8.3 Addresses for Notices; Requests for Accounting. Except as
otherwise expressly provided herein, all notices, requests, demands and other
communications provided for under the Loan Documents shall be in writing and
shall be (a) personally delivered, (b) sent by first class United States mail,
(c) sent by overnight courier of national reputation, or (d) transmitted by
telecopy, in each case addressed or telecopied to the party to whom notice is
being given at its address or telecopier number as set forth below next to its
signature or, as to each party, at such other address or telecopier number as
may hereafter be designated by such party in a written notice to the other party
complying as to delivery with the terms of this Section. All such notices,
requests, demands and other communications shall be deemed to have been given on
(a) the date received if personally delivered, (b) when deposited in the mail if
delivered by mail, (c) the date sent if delivered by overnight courier, or (d)
the date of transmission if delivered by telecopy, except that notices or
requests delivered to the Lender pursuant to any of the provisions of Article II
shall not be effective until received by the Lender. All requests under Section
9-210 of the UCC (i) shall be made in a writing signed by a Person authorized
under Section 2.2(a), (ii) shall be personally delivered, sent by registered or
certified mail, return receipt requested, or by overnight courier of national
reputation, (iii) shall be deemed to be sent when received by the Lender and
(iv) shall otherwise comply with the requirements of Section 9-210. The Borrower
requests that the Lender respond to all such requests which on their face appear
to come from an authorized individual and releases the Lender from any liability
for so responding. The Borrower shall pay the Lender the maximum amount allowed
by law for responding to such requests.

         Section 8.4 Further Documents. The Borrower will from time to time
execute, deliver, endorse and authorize the filing of any and all instruments,
documents, conveyances, assignments, security agreements, financing statements,
control agreements and other agreements and writings that the Lender may
reasonably request in order to secure, protect, perfect or enforce the Security
Interest or the Lender's rights under the Loan Documents (but any failure to
request or assure that the Borrower executes, delivers, endorses or authorizes
the filing of any such item shall not affect or impair the validity, sufficiency
or enforceability of the Loan Documents and the Security Interest, regardless of
whether any such item was or was not executed, delivered or endorsed in a
similar context or on a prior occasion).

         Section 8.5 Costs and Expenses. The Borrower shall pay on demand all
costs and expenses, including reasonable attorneys' fees, incurred by the Lender
in connection with the Obligations, this Agreement, the Loan Documents, any
Letter of Credit and any other document or agreement related hereto or thereto,
and the transactions contemplated hereby, including all such costs, expenses and
fees incurred in connection with the negotiation, preparation, execution,
amendment, administration, performance, collection and enforcement of the
Obligations and all

                                      -45-
<PAGE>

such documents and agreements and the creation, perfection, protection,
satisfaction, foreclosure or enforcement of the Security Interest.

         Section 8.6 Indemnity. In addition to the payment of expenses pursuant
to Section 8.5, the Borrower shall indemnify, defend and hold harmless the
Lender, and any of its participants, parent corporations, subsidiary
corporations, affiliated corporations, successor corporations, and all present
and future officers, directors, employees, attorneys and agents of the foregoing
(the "Indemnitees") from and against any of the following (collectively,
"Indemnified Liabilities"):

                  (i)      any and all transfer taxes, documentary taxes,
         assessments or charges made by any governmental authority by reason of
         the execution and delivery of the Loan Documents or the making of the
         Advances;

                  (ii)     any claims, loss or damage to which any Indemnitee
         may be subjected if any representation or warranty contained in Section
         5.14 proves to be incorrect in any respect or as a result of any
         violation of the covenant contained in Section 6.11(b); and

                  (iii)    any and all other liabilities, losses, damages,
         penalties, judgments, suits, claims, costs and expenses of any kind or
         nature whatsoever (including the reasonable fees and disbursements of
         counsel) in connection with the foregoing and any other investigative,
         administrative or judicial proceedings, whether or not such Indemnitee
         shall be designated a party thereto, which may be imposed on, incurred
         by or asserted against any such Indemnitee, in any manner related to or
         arising out of or in connection with the making of the Advances and the
         Loan Documents or the use or intended use of the proceeds of the
         Advances.

If any investigative, judicial or administrative proceeding arising from any of
the foregoing is brought against any Indemnitee, upon such Indemnitee's request,
the Borrower, or counsel designated by the Borrower and satisfactory to the
Indemnitee, will resist and defend such action, suit or proceeding to the extent
and in the manner directed by the Indemnitee, at the Borrower's sole costs and
expense. Each Indemnitee will use its best efforts to cooperate in the defense
of any such action, suit or proceeding. If the foregoing undertaking to
indemnify, defend and hold harmless may be held to be unenforceable because it
violates any law or public policy, the Borrower shall nevertheless make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. The Borrower's obligation
under this Section 8.6 shall survive the termination of this Agreement and the
discharge of the Borrower's other obligations hereunder.

         Section 8.7 Participants. The Lender and its participants, if any, are
not partners or joint venturers, and the Lender shall not have any liability or
responsibility for any obligation, act or omission of any of its participants.
All rights and powers specifically conferred upon the Lender may be transferred
or delegated to any of the Lender's participants, successors or assigns.

         Section 8.8 Execution in Counterparts; Telefacsimile Execution. This
Agreement and other Loan Documents may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed to be
an original and all of which counterparts, taken

                                      -46-
<PAGE>

together, shall constitute but one and the same instrument. Delivery of an
executed counterpart of this Agreement by telefacsimile shall be equally as
effective as delivery of an original executed counterpart of this Agreement. Any
party delivering an executed counterpart of this Agreement by telefacsimile also
shall deliver an original executed counterpart of this Agreement but the failure
to deliver an original executed counterpart shall not affect the validity,
enforceability, and binding effect of this Agreement.

         Section 8.9 Retention of Borrower's Records. The Lender shall have no
obligation to maintain any electronic records or any documents, schedules,
invoices, agings, or other papers delivered to the Lender by the Borrower or in
connection with the Loan Documents for more than four months after receipt by
the Lender.

         Section 8.10 Binding Effect; Assignment; Complete Agreement; Exchanging
Information. The Loan Documents shall be binding upon and inure to the benefit
of the Borrower and the Lender and their respective successors and assigns,
except that the Borrower shall not have the right to assign its rights
thereunder or any interest therein without the Lender's prior written consent.
To the extent permitted by law, the Borrower waives and will not assert against
any assignee any claims, defenses or set-offs which the Borrower could assert
against the Lender. This Agreement shall also bind all Persons who become a
party to this Agreement as a borrower. This Agreement, together with the Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and supersedes all prior agreements, written or oral, on
the subject matter hereof. Without limiting the Lender's right to share
information regarding the Borrower and its Affiliates with the Lender's
participants, accountants, lawyers and other advisors, the Lender, Wells Fargo &
Company, and all direct and indirect subsidiaries of Wells Fargo & Company, may
exchange any and all information they may have in their possession regarding the
Borrower and its Affiliates, and the Borrower waives any right of
confidentiality it may have with respect to such exchange of such information.

         Section 8.11 Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable shall be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof.

         Section 8.12 Headings. Article, Section and subsection headings in this
Agreement are included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose.

         Section 8.13 Governing Law; Jurisdiction, Venue; Waiver of Jury Trial.
The Loan Documents shall be governed by and construed in accordance with the
substantive laws (other than conflict laws) of the State of Colorado. The
parties hereto hereby (i) consent to the personal jurisdiction of the state and
federal courts located in the State of Colorado in connection with any
controversy related to this Agreement; (ii) waive any argument that venue in any
such forum is not convenient; (iii) agree that any litigation initiated by the
Lender or the Borrower in connection with this Agreement or the other Loan
Documents may be venued in either the state or federal courts located in the
City and County of Denver, Colorado; and (iv) agree that a final judgment in any
such suit, action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
THE PARTIES WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING

less, the aggregate unpaid principal amount of all Revolving Advances made by
the Lender to the Borrower under the Credit Agreement (defined below) together
with interest on the principal amount hereunder remaining unpaid from time to
