                  Section 2. Funding Obligation and Procedure.

                  (a) Funding. RERC hereby irrevocably agrees to make Fundings
to RENH in the amount that RENH is obligated to advance to REMA under the
Subordinated Working Capital Facility on or before (i) the first Rent Payment
Date after its receipt of a Cash Flow Coverage Certificate specifying a Cash
Deficiency Amount and (ii) ten Business Days after its receipt of a Cash Flow
Coverage Certificate specifying an Interim Cash Deficiency Amount but, in each
case, in no event in excess of the undrawn amount of the Commitment. RERC shall
make all Fundings in U.S. Dollars. All Fundings shall be in immediately
available funds paid directly to RENH. The obligation of RENH in respect of each
Funding shall be evidenced by, at the sole option of RERC, (x) a note in the
form of Exhibit A attached hereto in the principal amount of such Funding or (y)
Capital Stock in the number shares equal to the aggregate amount of such Funding
divided by the Issue Price.

                  (b) Delivery of Evidence of Funding. REHN agrees to deliver to
RERC promptly after receipt of the Funding an appropriately completed note or
stock certificate, as applicable, evidencing the Funding.

                  (c) Proceeds. The proceeds of a Fundings Loan shall be used
solely to make advances to REMA under the Subordinated Working Capital Facility.

                  (d) Payments and Reborrowing. RENH shall make payments to RERC
to be applied to RENH's obligation respecting the Fundings in an amount equal to
any amounts paid or prepaid to RENH by REMA in respect of the Subordinated
Working Capital Facility upon RENH's receipt of such payment. Any payment or
prepayment on a Funding constituting a Loan shall be applied to first to the
accrued and unpaid interest on such Loan and then to principal of such Loan. Any
payment or prepayment on a Funding constituting Capital Stock shall be applied
in redemption of such Capital Stock at a price equal to the Put Price.

otherwise.

                  "Telerate" means, when used in connection with any designated
page and the "LIBOR" rate, the display page so designated on the Dow Jones
Telerate Service (or such other page as may replace that page on that service or
on any replacement Dow Jones Service for the purpose of displaying rates
comparable to the "LIBOR" rate).

         2. Subordination.

                  (a) The indebtedness evidenced by this Note and the other
obligations described in the definition of "Subordinated Indebtedness" is
subordinated and subject in right of payment to the prior payment in full of all
Senior Obligations (as hereinafter defined) of Facility Lessee. Each holder of
this Note, by its acceptance hereof, agrees to and shall be bound by all the
provisions hereof.

                  (b) No payment on account of rent, principal, premium or
interest on the Subordinated Indebtedness shall be made unless (a) full payment
of all amounts then due and payable with respect to Senior Obligations has been
made, (b) such payment would be permitted under the Senior Obligations and by
the Participation Agreements, (c) each of the applicable conditions, if any, set
forth in Section 5.4 of the Participation Agreements has been satisfied and (d)
immediately after giving effect to such payment, there shall not exist any
Significant Lease Default or Lease Event of Default. Any such payment permitted
pursuant to this paragraph is hereinafter referred to as a "Permitted Payment".
For the purposes of these provisions, no Senior Obligation shall be deemed to
have been paid in full until the obligee of such Senior Obligation shall have
indefeasibly received payment in full in cash. Any cash payment on the Senior
Obligations made by a Person which is solvent at the time of and after giving
effect to such payment shall be presumed to have been indefeasibly paid in full
in cash absent actual knowledge by the payor to the contrary.

                  (c) Upon any payment or distribution of assets of Facility
Lessee of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution or winding up or total or partial liquidation or
reorganization of Facility Lessee, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, then and in any such
event all amounts (including interest, indemnities and fees) due or to become
due upon all Senior Obligations shall first be paid in full before the holders
of the Subordinated Indebtedness shall be

                                       3
<PAGE>   4

entitled to retain any assets so paid or distributed in respect of the
Subordinated Indebtedness (for principal, premium, interest or otherwise) and
upon any such dissolution or winding up or liquidation or reorganization, any
payment or distribution of assets of Facility Lessee of any kind or character,
whether in cash, property or securities, to which the holders of the
Subordinated Indebtedness would be entitled, except as otherwise provided
herein, shall be paid by Facility Lessee or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment or
distribution, or by the holders of the Subordinated Indebtedness if received by
them, directly to the holders of the Senior Obligations or their representatives
for application to such Senior Obligations in accordance with their terms. So
long as any Senior Obligation is outstanding, the holder of this Note shall not
commence, or join with any creditor other than any Person to whom Senior
Obligations are owed, in commencing, or directly or indirectly causing Facility
Lessee to commence, or assist Facility Lessee in commencing, any proceeding
referred to in the preceding sentence.

                  (d) The holder of this Note hereby irrevocably authorizes and
empowers (without imposing any obligation on) each Person to whom any Senior
Obligation is owed and such Person's representatives, under the circumstances
set forth in the immediately preceding paragraph, to demand, sue for, collect
and receive every such payment or distribution described therein and give
acquittance therefor, to file claims and proofs of claims in any statutory or
nonstatutory proceeding, to vote such Person's ratable share of the full amount
of the Subordinated Indebtedness evidenced by this Note in its sole discretion
in connection with any resolution, arrangement, plan of reorganization,
compromise, settlement or extension and to take all such other action (including
the right to participate in any composition of creditors and the right to vote
such Person's ratable share of the Subordinated Indebtedness, evidenced by this
Note, at creditors' meetings for the election of trustees, acceptances of plans
and otherwise), in the name of the holder of the Subordinated Indebtedness
evidenced by this Note or otherwise, as such Person's representatives may deem
necessary or desirable for the enforcement of the subordination provisions of
this Note. The holder of this Note shall execute and deliver to each Person to
whom any Senior Obligation is owed and such Person's representatives all such
further instruments confirming the foregoing authorization, and all such powers
of attorney, proofs of claim, assignments of claim and other instruments, and
shall take all such other action as may be reasonably requested by such Person
or such Person's representatives in order to enable such holder to enforce all
claims upon or in respect of such Person's ratable share of the Subordinated
Indebtedness evidenced by this Note; provided, however, that nothing herein
shall obligate the holder of this Note to pay or incur any cost, expense or
liability or to take any action that may result in the imposition of any cost,
expense or liability.

                  (e) The holder of this Note shall not, without the prior
written consent of the various Owner Lessors and, so long as the Lien of the
various Lease Indentures shall not have been discharged or terminated in
accordance with the terms thereof, the Lease Indenture Trustee, have any right
to accelerate payment of, or institute any proceedings to enforce, the
Subordinated Indebtedness (other than a Permitted Payment) so long as any Senior
Obligation is outstanding.

                  (f) If any payment (other than a Permitted Payment) or
distribution of assets of Facility Lessee of any kind or character, whether in
cash, property or securities, shall be received by the holder of the
Subordinated Indebtedness before all Senior Obligations are paid in full,

                                       4
<PAGE>   5

such payment or distribution will be held in trust for the benefit of, and shall
be immediately paid over to, the holders of the Senior Obligations or their
representatives for application to such Senior Obligations in accordance with
their terms.

                  (g) Nothing contained in this Note is intended to or shall
impair as between Facility Lessee, its creditors (other than the holders of
Senior Obligations) and the holders of the Subordinated Indebtedness, the
obligations of Facility Lessee, to pay to the holders of the Subordinated
Indebtedness, as and when the same shall become due and payable in accordance
with their terms, or to affect the relative rights of the holders of the
Subordinated Indebtedness and creditors of Facility Lessee (other than holders
of Senior Obligations).

                  (h) The Persons to whom Senior Obligations are due shall not
be prejudiced in their rights to enforce the subordination contained herein in
accordance with the terms hereof by any act or failure to act on the part of
Facility Lessee.

                  (i) The holder of this Note agrees to execute and deliver such
further documents and to do such other acts and things as the Transaction
Parties may reasonably request in order fully to effect the purposes of these
subordination provisions. Each holder of this Note by its acceptance hereof
authorizes and directs the Transaction Parties on its behalf to take such
further action as may be necessary to effectuate the subordination as provided
herein and appoints the various Lease Indenture Trustees, so long as the Lien of
the Lease Indentures shall not have been terminated or discharged in accordance
with the terms thereof and thereafter the various Owner Lessors, as its
attorney-in-fact for any and all such purposes.

                  (j) The subordination effected by these provisions, and the
rights of the Persons to whom Senior Obligations are owed, shall not be affected
by (i) any amendment of, or addition or supplement to any Operative Document, or
any other document evidencing or securing any Senior Obligation, (ii) any
exercise or nonexercise of any right, power or remedy under or in respect of any
Operative Document, or any other document evidencing or securing any Senior
Obligation or (iii) any waiver, consent, release, indulgence, extension,
renewal, modification, delay, or other action, inaction or omission, in respect
of, any Operative Document, or any other document evidencing or securing any
Senior Obligation, whether or not any holder of any Subordinated Indebtedness
shall have had notice or knowledge of any of the foregoing. No failure on the
part of any holder of a Senior Obligation to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

                  (k) The holder of this Note and Facility Lessee each hereby
waive promptness, diligence, notice of acceptance and any other notice with
respect to any Senior Obligation and these terms of subordination and any
requirement that any Transaction Party protect, secure, perfect or insure any
Lien or any property subject thereto or exhaust any right to take any action
against Facility Lessee any other Person or any collateral.

                                       5
<PAGE>   6

                  (l) These terms of subordination shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any Senior Obligation is rescinded or must otherwise be returned by the Person
to whom such Senior Obligation is owed upon the insolvency, bankruptcy or
reorganization of Facility Lessee or otherwise, all as though such payment had
not been made.

                  (m) The provisions of these terms of subordination constitute
a continuing agreement and shall (i) remain in full force and effect until each
of the Facility Leases has been terminated and all amounts owed thereunder have
been paid and the Lien of the Lease Indentures has been terminated or discharged
in accordance with their terms, (ii) be binding upon the holder of this Note and
Facility Lessee and their respective successors, transferees and assignees and
(iii) inure to the benefit of, and be enforceable by, the Transaction Parties.
Without limiting the generality of the foregoing clause (iii), the Transaction
Parties may assign or otherwise transfer all or any portion of their rights and
obligations under all or any of the Operative Documents to any other Person (to
the extent permitted by the Operative Documents), and such other Person shall
thereupon become vested with all the rights in respect thereof granted to the
Transaction Parties herein or otherwise.

         3. Advances. Lender shall make advances (the "Loans") to the Facility
Lessee hereunder in accordance with this Section 3:

                  (a) Between ten and three Business Days before any Rent
Payment Date, the Facility Lessee shall deliver to the Lender and Reliant Energy
Resources Corp., a Delaware corporation ("RERC"), a certificate (the "Pro Forma
Coverage Certificate") setting forth its computation in reasonable detail of the
Pro Forma Coverage Ratio for the six-month (or shorter period from the Closing
Date) period ending on such Rent Payment Date. In the event that such Pro Forma
Coverage Ratio is less than 1.1 to 1.0, such certificate shall specify the
amount (the "Cash Deficiency Amount"), which, if added to the pro forma Cash
Flow Available for Fixed Charges included in such computation of Pro Forma
Coverage Ratio, would make the Pro Forma Coverage Ratio equal to 1.1 to 1.0.
Lender shall irrevocably make Loans to Facility Lessee, and Facility Lessee
irrevocably agrees to borrow such Loans from Lender, on such Rent Payment Date
in the amount equal to the lesser of (x) the Cash Deficiency Amount, if any,
relating to such Rent Payment Date and (y) the undrawn amount of the Commitment.

                  (b) From time to time, the Facility Lessee may deliver to the
Lender and RERC a Pro Forma Coverage Certificate setting forth its computation
in reasonable detail of the Pro Forma Coverage Ratio for the six-month (or
shorter period from the Closing Date) period ending on the last day of the month
in which delivery of such certificate occurs demonstrating that such Pro Forma
Coverage Ratio is less than 1.1 to 1.0 and specifying the amount (the "Interim
Cash Deficiency Amount"), which, if added to the pro forma Cash Flow Available
for Fixed Charges included in such computation of Pro Forma Coverage Ratio,
would make the Pro Forma Coverage Ratio equal to 1.1 to 1.0. Lender shall make
Loans to Facility Lessee, within ten Business Days after delivery of such
certificate in an amount equal to the lesser of (x) the Interim Cash Deficiency
Amount, on the date such certificate was delivered and (y) the undrawn amount of
the Commitment.

                                       6
<PAGE>   7

                  (c) Repayment of the Loans is subject to Section 2. Facility
Lessee may borrow, repay and reborrow amounts available under the Commitment in
accordance with Section 3.

                  (d) Lender shall, on the Business Day on which the Loan is to
be advanced, credit Facility Lessee's bank account with the amount of the Loan,
in immediately available funds. All Loans made by Lender to Facility Lessee and
all repayments of the principal thereof and interest thereon shall be recorded
by Lender on the schedule attached hereto, or on a continuation of such schedule
to be attached to and made a part hereof, and any such recordation shall
constitute prima facie evidence of the accuracy of such information so recorded;
provided, however, that the failure of Lender to record any such Loans and
repayments on the schedule attached hereto shall not diminish Facility Lessee's
obligation to repay all principal outstanding under any Loan and to pay all
interest accrued and unpaid in respect of any Loan under this Note in accordance
with its terms.

         4. Interest. Each Loan shall bear interest at a varying rate per annum
equal to the lesser of (a) the LIBOR Rate plus 3.50% per annum, such varying
rate to change automatically every calendar month, effective as of the first day
of each calendar month, to reflect the LIBOR Rate in effect on such day,
commencing August 24, 2000 and on the first day of each calendar month
thereafter, without notice to Facility Lessee or any other person or (b) the
highest rate permitted under applicable law (the "Maximum Lawful Rate"). All
calculations of interest hereunder shall be made on the basis of a year of 360
days for the actual number of days (including the first day but excluding the
last day) occurring in the period for which interest is payable. Payment of
interest on the Loans is subject to Section 2.

         5. Authorized Officers. The President of Facility Lessee or any person
from time to time designated to Lender in writing by the President of Facility
Lessee, shall have authority, subject to Section 3, to borrow funds from Lender
hereunder, subject to Section 2, to make interest payments hereunder, to give
notices of and, subject to Section 2, to make repayments of Loans outstanding
hereunder.

         6. Notices. All written notices hereunder shall be sent to the
respective parties at the addresses set forth above, Attention: President. All
telephone borrowing notices to Lender shall be made to James E. Hammelman,
(713)207-3351.

         7. Maturity and Scheduled Payments. Subject to Section 2 and subject to
the right of the holder of this Note to accelerate the maturity hereof as
hereinafter described (which is subject to Section 2), the principal of this
Note shall be due and payable on the Maturity Date and accrued and unpaid
interest on the principal amount outstanding on this Note shall be due and
payable to Lender at its address set forth above as it accrues quarterly on each
January 1, April 1, July 1 and October 1 throughout the term of this Note,
beginning on October 1 2000, until all unpaid principal and accrued and unpaid
interest on this Note shall be paid in full.

         8. Prepayments. Subject to Section 2, at any time, Facility Lessee may
prepay any amounts owing hereunder in whole or in part, without penalty. If any
payment of principal or interest on this Note shall become due on a day that is
not a Business Day, such payment shall be made on the next succeeding Business
Day and such extension of time shall in such case be

                                       7
<PAGE>   8

included in computing interest in connection with such payment. All payments
made in accordance with this Note are to be made in lawful money of the United
States of America in same day funds at the locations specified herein, or such
other place as Lender shall designate in writing to Facility Lessee.

         9. Events of Default. If any of the following events (each, an "Event
of Default") shall occur and be continuing, the obligation of Lender to make any
further advance hereunder shall terminate and the outstanding principal balance
of this Note, together with accrued and unpaid interest and any other sums that
Facility Lessee may owe to Lender under or in connection with this Note or
otherwise (collectively, the "Obligations") shall automatically become
immediately due and payable, without any further notice of any kind to Facility
Lessee, all of which notices are expressly waived below:

                  (a) the Facility Lessee (i) admits in writing its inability to
         pay its debts generally as they become due; (ii) generally fails to pay
         its debts as they become due; (iii) files a petition or answer seeking
         for itself, or consenting to or acquiescing in any reorganization,
         arrangement, composition, readjustment, liquidation, dissolution or
         similar relief under, any bankruptcy law or any insolvency law or other
         law for the relief or aid of debtors (including, without limitation,
         the Bankruptcy Code or any amendment thereto); or (iv) makes an
         assignment for the benefit of its creditors; or

                  (b) there is appointed a receiver, custodian, liquidator,
         fiscal agent or trustee of Facility Lessee or of the whole or any
         substantial part of its properties or assets, or any court enters an
         order, judgment or decree approving a petition filed against Facility
         Lessee seeking reorganization, arrangement, composition, readjustment,
         liquidation, dissolution or similar relief under any law referred to in
         paragraph (b) above and either such order, judgment or decree so filed
         against it is not dismissed or stayed (unless and until such stay is no
         longer in effect) within 30 days of entry thereof or an order for
         relief is entered pursuant to any such law.

         10. Maximum Lawful Rate. Nothing contained in this Note or any other
document executed in connection herewith is intended to require Facility Lessee
to pay interest (including fees, charges or expenses or any other amounts which,
under applicable law, are deemed interest) for the account of Lender at a rate
exceeding the Maximum Lawful Rate.

                  All agreements between Facility Lessee and Lender, whether now
existing or hereafter arising and whether written or oral, are hereby expressly
limited so that in no contingency or event whatsoever, whether by reason of
demand being made on this Note, prepayment or otherwise, shall the amount paid,
or agreed to be paid, to the Lender for the use, forbearance, or detention of
the money to be loaned under this Note or otherwise or for the payment or
performance of any covenant or obligation contained herein or in any other
document executed in connection herewith exceed the Maximum Lawful Rate. If the
amount of any interest (including fees, charges or expenses or any other amounts
which, under applicable law, are deemed interest) contracted for, taken,
reserved, charged or received by or for the account of Lender, would exceed the
Maximum Lawful Rate, then, ipso facto, the amount of such interest payable for
the account of Lender shall be automatically reduced to such Maximum

                                       8
<PAGE>   9

Lawful Rate, and if, from any such circumstance, Lender shall ever receive
interest or anything which might be deemed interest under applicable law which
would exceed the Maximum Lawful Rate, such amount which would be excessive
interest shall be applied to the reduction of the principal amount owing on
account of this Note held by Lender and not to the payment of interest, or if
such excessive interest exceeds the unpaid balance of principal of such Note,
such excess shall be refunded to Facility Lessee. All sums paid or agreed to be
paid to Lender for the use, forbearance or detention of the indebtedness of
Facility Lessee to Lender shall, to the extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full of the principal (including the period of any
renewal or extension thereof) so that the interest on account of such
indebtedness shall not exceed the Maximum Lawful Rate.

         11. Expenses. In addition to all principal and accrued interest on this
Note, Facility Lessee agrees, subject to Section 2, to pay (i) all reasonable
costs and expenses incurred by all owners and holders of this Note in collecting
this Note through any probate, reorganization, bankruptcy or any other
proceeding; (ii) reasonable attorneys' fees when and if this Note is placed in
the hands of an attorney for collection after default; and (iii) all attorneys'
fees related to the preparation and execution of this Note and any document,
agreement or instrument executed in connection with or given as security for
this Note.

         12. Waivers. Facility Lessee and any and all endorsers, guarantors and
sureties severally waive grace, presentment for payment, notice of dishonor,
protest and notice of protest and diligence in collecting and bringing of suit
against any party hereto. Facility Lessee and any and all endorsers, guarantors
and sureties further agree: (i) to all renewals, extensions, amendments and
modifications hereof without limit, or partial payments hereon; (ii) to any
release or substitution of security herefor, in whole or in part, or any release
or discharge of any guarantor, surety, or co-maker, with or without notice,
before or after maturity; (iii) that waiver of any default shall not constitute
waiver of any prior or subsequent default; and (iv) that no remedy, right or
power conferred upon Lender or the holder of this Note is intended to be
exclusive of any other remedy, right or power given hereunder or now or
hereafter available at law, in equity or otherwise. This Note may be transferred
by Lender, and the rights and privileges of Lender under this Note shall inure
to the benefit of Lender's representatives, successors and assigns.

         13. Proceeds. The proceeds of the Loans shall be used exclusively for
the purpose of financing operating expenses, excluding Capital Expenditures, and
Senior Obligations and shall not be used directly or indirectly to finance the
payment of Indebtedness subordinated to the Senior Obligations or any other
Restricted Payments. The Loans are for business, commercial, or investment
purposes and none of such proceeds shall be used for personal, consumer, family
household or agricultural purposes or for purchasing or carrying margin stock.

         14. Governing Law. This Note shall be governed by and construed in
accordance with, the laws of the State of New York but without giving effect to
the conflict of laws principles thereof.

         15. Final Agreement. THIS NOTE AND THE OTHER DOCUMENTS, AGREEMENTS AND
INSTRUMENTS EXECUTED IN CONNECTION HEREWITH REPRESENT THE FINAL AGREEMENT
BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
