                           LOAN AND SECURITY AGREEMENT

     This Loan and Security Agreement ("AGREEMENT") is between the undersigned
Borrower and the undersigned Lender concerning loans and other credit
accommodations to be made by Lender to Borrower. Certain terms are defined
within this Agreement and within Section 10 hereof.

1.   PARTIES

     1.1 Borrower. The "BORROWER" is identified in Section 10.5(c) and its
successors and assigns. If more than one Borrower is specified in Section
10.5(c), all references to Borrower shall mean each of them, jointly and
severally, individually and collectively, and the successors and assigns of
each.

     1.2 Lender. The "LENDER" is THE CIT GROUP/BUSINESS CREDIT, INC. and its
agents, designees, representatives, successors and assigns.

2.   LOANS AND OTHER CREDIT ACCOMMODATIONS

     2.1 Revolving Loans. Lender shall, subject to the terms and conditions
contained herein, make revolving loans to Borrower ("REVOLVING LOANS") in
amounts requested by Borrower from time to time, but (i) not in excess of the
Net Availability existing immediately prior to the making of the requested loan,
(ii) proceeds of the Revolving Loans shall not be used to acquire inventory in
excess of the Inventory Sublimit set forth in Section 10.1(c), (iii) provided
the requested loan would not cause the outstanding Obligations to exceed the
Maximum Credit and (iv) provided that any Revolving Loans that may be made due
to the inclusion of clause (vi) within the definition of Gross Availability
shall be (x) made quarterly and (y) shall be repaid within fourteen (14) days
after such Revolving Loan is made, unless otherwise agreed by Lender.

     (a) The "MAXIMUM CREDIT" is set forth in Section 10.1(a).

     (b) The "GROSS AVAILABILITY" is at any time (i) the product of the
outstanding amount of Eligible Accounts, multiplied by the Eligible Accounts
Percentage set forth in Section 10.1(b), plus (ii) the product(s) obtained by
multiplying the applicable Eligible Inventory Percentage(s) for Finished Goods,
if any, set forth in Section 10.1(b) by the values (based on the lower of cost
or market value) of Eligible Inventory that is finished goods, plus (iii) the
product(s) obtained by multiplying the applicable Eligible Inventory
Percentage(s) for Component Goods, if any, set forth in Section 10.1(b) by the
values (based on the lower of cost, market or appraised value) of Eligible
Inventory that is component parts, plus (iv) the product(s) obtained by
multiplying the applicable Eligible Inventory Percentage(s) for work in
progress, plus (v) $1,000,000, if any, set forth in Section 10.1(b) by the
values (based on the lower of cost, market or appraised value) of Eligible
Inventory that is work in progress, but the amount so added under subsections
(ii), (iii), (iv) and (v) hereof shall not exceed any sublimits set forth in
Section 10.1(c) plus (vi) any cash in an amount not to exceed $7,500,000 secured
by a Pledge Agreement and a Control Agreement as described in Section 4.5
hereto, provided that such cash may be included within the calculation of Gross
Availability only if no Event of Default exists and at Lender's sole discretion.

     (c) The "NET AVAILABILITY" shall be calculated at any time as an amount
equal to the Gross Availability minus the aggregate amount of all
then-outstanding Obligations to Lender.

     (d) "ELIGIBLE ACCOUNTS" are accounts created by Borrower in the ordinary
course of its business which are and remain acceptable to Lender for lending
purposes. General criteria for Eligible Accounts are set forth below but may be
revised from time to time by Lender, in its sole judgment, on thirty (30) days'
prior written notice to Borrower. Lender shall, in general, deem and continue to
deem accounts to be Eligible Accounts if: (1) such accounts arise from bona fide
completed transactions and have not remained unpaid for more than the number of
days after the invoice date set forth in Section 10.1(d); (2) the amounts of the
accounts reported to Lender are absolutely owing to Borrower and

<PAGE>   5

payment is not conditional or contingent, (such as consignments, guaranteed
sales or right of return or other similar terms); (3) the account debtor's chief
executive office or principal place of business is located in the United States
or Lender has expressly approved as an eligible account debtor an account debtor
whose chief executive office or principal place of business is not located in
the United States; (4) such accounts do not arise from progress billings,
unbilled receivables, retainages or bill and hold sales not to exceed $2,000,000
(unless Lender is provided with proper identification, acceptable backlog,
tri-party documentation, and such accounts are less than 45 days from the date
of invoice, all satisfactory to Lender in its reasonable discretion); (5) there
are no contra relationships, setoffs, counterclaims or disputes existing with
respect thereto and there are no other facts existing or threatened which would
impair or delay the collectibility of all or any portion thereof, unless waived
by Lender; (6) the goods giving rise thereto were not at the time of the sale
subject to any liens except those permitted in this Agreement; (7) such accounts
are not accounts with respect to which the account debtor or any officer or
employee thereof is an officer, employee or agent of or is affiliated with
Borrower, directly or indirectly, whether by virtue of family membership,
ownership, control, management or otherwise; (8) there has been compliance with
the Assignment of Claims Act or similar State or local law, if applicable, if
the account debtor is the United States or any domestic governmental unit; (9)
Borrower has delivered to Lender such documents as Lender may have requested
pursuant to Section 5.9 hereof in connection with such accounts and Lender shall
have received verifications of such accounts, satisfactory to it, if sent to the
account debtors or any other obligors or any bailees pursuant to Section 5.5
hereof; (10) there are no known facts existing or threatened which might result
in any adverse change in the account debtor's financial condition; (11) accounts
owed by an account debtor and its affiliates do not represent more than
thirty-five percent (35%) of all otherwise Eligible Accounts (the amount
exceeding thirty-five percent (35%) shall not be eligible); (12) not more than
fifty percent (50%) of the accounts of an account debtor or its affiliates owed
to Borrower are more than the number of days set forth in Section 10.1(d),
except not more than twenty-five percent (25%) of the accounts described in
subsection (4) as bill and hold sales are more than forty-five (45) days from
invoice date; (13) such accounts are owed by account debtors whose total
indebtedness to Borrower does not exceed the amount of any customer credit
limits as established from time to time on notice to Borrower (the amount
exceeding the credit limit shall not be eligible); and (14) such accounts are
owed by account debtors deemed creditworthy at all times by Lender.

     (e) "ELIGIBLE INVENTORY" is inventory owned by Borrower which is and
remains acceptable to Lender for lending purposes and is located at one of the
addresses set forth in Section 10.5(e).

     (f) Lender shall have a continuing right to reduce the Gross Availability
by implementing Reserves ("RESERVES"), and to increase and decrease such
Reserves from time to time, if and to the extent that, in Lender's sole
judgment, such Reserves are necessary to protect Lender against any state of
facts which does, or would, with notice or passage of time or both, constitute
an Event of Default or have an adverse effect on any Collateral. Customer
Deposits and Letter of Credit Guaranties shall constitute Reserves reducing
Gross Availability.

     (g) If a voluntary or involuntary petition under the Bankruptcy Code is
filed against Borrower, then Lender need not make loans or issue Letters of
Credit.

     (h) Revolving Loans and Letters of Credit will not at any time exceed the
Gross Availabiity unless Lender has consented.

     2.2 Letters of Credit. In order to assist Borrower in establishing or
opening Letters of Credit with an Issuing Bank, Borrower has requested Lender to
join in the applications for such Letters of Credit, and/or guarantee payment or
performance of such Letters of Credit and any drafts or acceptances thereunder
through the issuance of the Letter of Credit Guaranty, thereby lending Lender's
credit to Borrower and Lender has agreed to do so. These arrangements shall be
handled by Lender subject to the terms and conditions set forth below.

     (a) "ISSUING BANK" shall mean the bank issuing Letters of Credit for
Borrower.

     (b) "LETTERS OF CREDIT" shall mean all letters of credit issued with the
assistance of Lender in accordance with Section 2.2 hereof by the Issuing Bank
for or on behalf of Borrower.

Borrower under Section 3.4(f) of this Agreement for: (i) issuing a Letter of
Credit Guaranty, and/or (ii) otherwise aiding Borrower in obtaining Letters of
Credit, all pursuant to Sections 2.2 and 3.4 hereof.

     (e) "LETTER OF CREDIT SUB-LINE" shall mean the commitment of Lender to
assist Borrower in obtaining Letters of Credit, pursuant to Section 2.2 hereof,
in an aggregate amount of $l,000,000.

     (f) Within the Maximum Credit and Net Availability, Lender shall assist
Borrower in establishing or opening Letters of Credit in an amount not to exceed
the outstanding amount of the Letter of Credit Sub-Line. Lender's assistance for
amounts in excess of the limitation set forth herein shall at all times and in
all respects be in Lender's sole discretion. It is understood that the term,
form and purpose of each Letter of Credit and all documentation in connection
therewith, and any amendments, modifications or extensions thereof, must be
mutually acceptable to Lender, the Issuing Bank and Borrower. Any and all
outstanding Letters of Credit shall be reserved dollar for dollar from Net
Availability as a Reserve.

     (g) Lender shall have the right, without notice to Borrower, to charge
Borrower's Revolving Loan Account (as defined in Section 5 hereof) with the
amount of any and all indebtedness, liability or obligation of any kind incurred
by Lender under the Letters of Credit Guaranty at the earlier of a) payment by
Lender under the Letters of Credit Guaranty, or b) the occurrence of an Event of
Default. Any amount charged to Borrower's Revolving Loan Account shall be deemed
a Revolving Loan hereunder and shall incur interest at the rate provided in
Section 3 of this Agreement.

     (h) BORROWER UNCONDITIONALLY INDEMNIFIES LENDER AND HOLDS LENDER HARMLESS
FROM ANY AND ALL LOSS, CLAIM OR LIABILITY INCURRED BY LENDER ARISING FROM ANY
TRANSACTIONS OR OCCURRENCES RELATING TO LETTERS OF CREDIT ESTABLISHED OR OPENED
FOR BORROWER'S ACCOUNT, THE COLLATERAL RELATING THERETO AND ANY DRAFTS OR
ACCEPTANCES THEREUNDER, AND ALL OBLIGATIONS THEREUNDER, INCLUDING ANY SUCH LOSS
OR CLAIM DUE TO ANY ERRORS, OMISSIONS, NEGLIGENCE, MISCONDUCT OR ACTION TAKEN BY
ANY ISSUING BANK, OTHER THAN FOR ANY SUCH LOSS, CLAIM OR LIABILITY ARISING OUT
OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT BY LENDER UNDER THE LETTERS OF
CREDIT GUARANTY. THIS INDEMNITY SHALL SURVIVE TERMINATION OF THIS AGREEMENT.
BORROWER AGREES THAT ANY CHARGES INCURRED BY LENDER FOR BORROWER ACCOUNT BY THE
ISSUING BANK SHALL BE CONCLUSIVE ON LENDER AND MAY BE CHARGED TO BORROWER'S
REVOLVING LOAN ACCOUNT.

     (i) Lender shall not be responsible for: the existence, character, quality,
quantity, condition, packing, value or delivery of the goods purporting to be
represented by any documents; any difference or variation in the character,
quality, quantity, condition, packing, value or delivery of the goods from that
expressed in the documents; the validity, sufficiency or genuineness of any
documents or of any endorsements thereon, even if such documents should in fact
prove to be in any or all respects invalid, insufficient, fraudulent or forged;
the time, place, manner or order in which shipment is made; partial or
incomplete shipment, or failure or omission to ship any or all of the goods
referred to in the Letters of Credit or documents; any deviation from
instructions; delay, default, or fraud by the shipper and/or anyone else in
connection with the goods or the shipping thereof; or any breach of contract
between the shipper or vendors and Borrower.

     (j) Borrower agrees that any action taken by Lender, if taken in good
faith, or any action taken by any Issuing Bank, under or in connection with the
Letters of Credit, the guarantees, the drafts or acceptances, or the Collateral,
shall be binding on Borrower and shall not put Lender in any resulting liability
to Borrower. In furtherance thereof, Lender shall have the full right and
authority to clear and resolve any questions of non-compliance of documents; to
give any instructions as to acceptance or rejection of any documents or goods;
to execute any and all steamship or

                                       -3-
<PAGE>   7

airways guaranties (and applications therefore), indemnities or delivery orders;
to grant any extensions of the maturity of, time of payment for, or time of
presentation of, any drafts, acceptances, or documents; and to agree to any
amendments, renewals, extensions, modifications, changes or cancellations of any
of the terms or conditions of any of the applications, Letters of Credit, drafts
or acceptances; all in Lender's sole name, and the Issuing Bank shall be
entitled to comply with and honor any and all such documents or instruments
executed by or received solely from Lender, all without any notice to or any
consent from Borrower. Notwithstanding any prior course of conduct or dealing
with respect to the foregoing including amendments and non-compliance with
documents and/or Borrower's instructions with respect thereto, Lender shall
exercise its rights hereunder in its sole and reasonable business judgement. In
addition, without Lender's express consent and endorsement in writing, Borrower
agrees: (a) not to execute any and all applications for steamship or airway
guaranties, indemnities or delivery orders; to grant any extensions of the
maturity of, time of payment for, or time of presentation of, any drafts,
acceptances or documents; or to agree to any amendments, renewals, extensions,
modifications, changes or cancellations of any of the terms or conditions of any
of the applications, Letters of Credit, drafts or acceptances; and (b) after the
occurrence of an Event of Default which is not cured within any applicable grace
period, if any, or waived by Lender, not to (i) clear and resolve any questions
of non-compliance of documents, or (ii) give any instructions as to acceptances
or rejection of any documents or goods.

     (k) Borrower agrees that any necessary import, export or other licenses or
certificates for the import or handling of the Collateral will have been
promptly procured; all foreign and domestic governmental laws and regulations in
regard to the shipment and importation of the Collateral, or the financing
thereof will have been promptly and fully complied with; and any certificates in
that regard that Lender may at any time request will be promptly furnished. In
this connection, Borrower warrants and represents that all shipments made under
any such Letters of Credit are in accordance with the laws and regulations of
the countries in which the shipments originate and terminate, and are not
prohibited by any such laws and regulations. Borrower assumes all risk,
liability and responsibility for, and agrees to pay and discharge, all present
and future local, state, federal or foreign taxes, duties, or levies. Any
embargo, restriction, laws, customs or regulations of any country, state, the
city, or other political subdivision, where the Collateral is or may be located,
or wherein payments are to be made, or wherein drafts may be drawn, negotiated,
accepted, or paid, shall be solely Borrower's risk, liability and
responsibility.

     (l) Upon any payments made to the Issuing Bank under the Letter of Credit
Guaranty, Lender shall acquire by subrogation, any rights, remedies, duties or
obligations granted or undertaken by Borrower to the Issuing Bank in any
application for Letters of Credit, any standing agreement relating to Letters of
Credit or otherwise, all of which shall be deemed to have been granted to Lender
and apply in all respects to Lender and shall be in addition to any rights,
remedies, duties or obligations contained herein.

     2.3 Minimum Excess Availability. Following the effective date of this
Agreement ("CLOSING DATE") and the application of the proceeds of the initial
Revolving Loan, Borrower must have Net Availability at least equal to the
Minimum Excess Availability amount set forth in Section 10.1(g) hereto, provided
that all of Borrower's indebtedness, liabilities, obligations and payables are
then current in accordance with Borrower's usual business practices.

3.   INTEREST AND FEES

     3.1 Interest.

     (a) Interest on the Revolving Loans shall be payable by Borrower on the
first day of each month, calculated upon the greater of (i) the closing daily
balances in the Revolving Loan Account of Borrower for each day during the
immediately preceding month or (ii) $3,000,000, at the lesser of (i) the Maximum
Rate set forth in Section 10.3(i) or (ii) the per annum rate set forth as the
Applicable Rate in Section 10.3(a). If at any time the Applicable Rate for any
Revolving Loan shall exceed the Maximum Rate, thereby causing the interest
accruing on such Revolving Loan to be limited to the Maximum Rate, then any
subsequent reduction in the Applicable Rate for such Revolving Loan shall not
reduce the rate of interest on such Revolving Loan below the Maximum Rate until
the aggregate amount of interest accrued on such Revolving Loan equals the
aggregate amount of interest which would have accrued on such Revolving Loan if
the Applicable Rate had at all times been in effect. The Applicable Rate shall
increase or decrease by an amount

                                      -4-

<PAGE>   8

equal to each increase or decrease, respectively, in the Applicable Rate,
effective as of the date of each such change. On and after any Event of Default
(which is not cured within any applicable grace period or waived by Lender) or
termination or non-renewal hereof, interest on all unpaid Obligations shall
accrue at a rate equal to the lesser of (i) the Maximum Rate or (ii) two percent
(2%) per annum in excess of the Applicable Rate otherwise payable, until such
time as all Obligations are indefeasibly paid in full (notwithstanding entry of
any judgment against Borrower or the exercise of any other right or remedy by
Lender), and all such interest shall be payable on demand. Interest shall in no
month be less than the Applicable Rate on the first day of such month multiplied
by the Minimum Borrowing set forth in Section 10.1(e). In no event shall charges
constituting interest exceed the rate permitted under any applicable law or
regulation, and if any provision of this Agreement is in contravention of any
such law or regulation, such provision shall be deemed amended to conform
thereto.

     3.2 Prime Rate Provisions.

     (a) All Revolving Loans shall be Prime Rate Loans unless Borrower is
permitted to designate Revolving Loans as LIBOR Loans pursuant to Section 3.3
hereof

     (b) "APPLICABLE PRIME RATE MARGIN" shall mean zero percent when Borrower
reports for the prior two consecutive quarters cumulative Net Income of at least
one dollar, as defined in Section 10.2 hereof, and shall mean one-half of one
percent when Borrower reports a cumulative Net Loss, as defined in Section 10.2
hereof, for the prior two consecutive fiscal quarters.

     (c) The "PRIME RATE" is the rate of interest publicly announced by The
Chase Manhattan Bank in New York, New York, or its successors and assigns from
time to time as its prime rate.

     (d) "PRIME RATE LOAN" shall mean any loans made pursuant to this Agreement
which are made or maintained at a rate of interest based upon the Prime Rate.

     3.3 LIBOR Provisions.

     (a) So long as (i) Borrower's average outstanding Revolving Loan balance
exceeds $10,000,000.00, (ii) Borrower has not reported a cumulative Net Loss for
the prior two consecutive fiscal quarters, and (iii) no Event of Default is in
effect, Borrower shall be permitted to designate Revolving Loans as LIBOR Loans
in accordance with this Section 3.3.

     (b) "APPLICABLE LIBOR MARGIN" shall mean for any day, the margin of
interest over LIBOR that is applicable when any Applicable Rate based on LIBOR
is determined under this Agreement. The Applicable LIBOR Margin is subject to
adjustment (upwards or downwards, as appropriate) based on Borrower's Fixed
Charge Coverage Ratio. Effective as of each Adjustment Date (as defined in
Section 6.11 hereof), the Applicable LIBOR Margin shall be adjusted as follows
based on the Fixed Charge Coverage Ratio as demonstrated by the most recently
delivered Compliance Certificate as required by Section 6.11 hereof:

After each adjustment of the Applicable LIBOR Margin in accordance herewith due
to a change in the Fixed Charge Coverage Ratio as demonstrated by the Compliance
Certificate, the new Applicable LIBOR Margin shall apply to all LIBOR Loans made
thereafter until the next Adjustment Date as of which the Compliance Certificate
demonstrates a change in the Fixed Charge Coverage Ratio to a level for which
another Applicable LIBOR Margin shall apply. Upon the request of Lender,
Borrower must demonstrate to the reasonable satisfaction of Lender the required
Fixed Charge Coverage Ratio in order to obtain an adjustment to a lower
Applicable LIBOR Margin. If Borrower fails to furnish to Lender any Compliance
Certificate (with accompanying financial statements) by the date required by
this Agreement, then the maximum Applicable LIBOR Margin shall apply at all
times after such date for all LIBOR Loans made or outstanding after such date
until Borrower furnishes the required Compliance Certificate (with accompanying
financial statements) to Lender.

     (c) "EUROCURRENCY RESERVE REQUIREMENTS" for any day, as applied to a LIBOR
Loan, shall mean the aggregate (without duplication) of the maximum rates
of reserve requirements (expressed as a decimal fraction) in effect with respect
to Lender and/or any present or future lender or participant on such day
(including, without limitation, basic, supplemental, marginal and emergency
reserves under Regulation D or any other applicable regulations of the Board of
Governors of the Federal Reserve System or other governmental authority having
jurisdiction with respect thereto, as now and from time to time in effect,
dealing with reserve requirements prescribed for Eurocurrency funding (currently
referred to as "Eurocurrency Liabilities" in Regulation D of such Board)
maintained by Lender and/or any such lenders or participants (such rate to be
adjusted to the nearest one sixteenth of one percent (1/16 of 1%) or, if there
is not a nearest one sixteenth of one percent (1/16 of 1%), to the next higher
one sixteenth of one percent (1/16 of 1%)).

     (d) "INTEREST PERIOD" shall mean:

         (i) with respect to any initial request by Borrower for a LIBOR Loan, a
30, 60 or 90 day period commencing on the borrowing or conversion date with
respect to a LIBOR Loan and ending 30, 60 or 90 days thereafter, as applicable;
and

         (ii) thereafter with respect to any continuation of, or conversion to,
a LIBOR Loan, at the option of Borrower, any 30, 60 or 90 days period commencing
on the last day of the immediately preceding Interest Period applicable to such
LIBOR Loan and ending 30, 60 or 90 days thereafter, as applicable;

     provided that, the foregoing provisions relating to Interest Periods are
subject to the following:

              (a) if any Interest Period would otherwise end on a day which is
not a Business Day, that Interest Period shall be extended to the next
succeeding Business Day, unless the result of such extension would

                                       -6-
<PAGE>   10

extend such payment into another calendar month in which event such Interest
Period shall end on the immediately preceding Business Day;

              (b) any Interest Period that begins on the last Business Day of a
calendar month (or on a day for which there is no numerically corresponding day
in the calendar month, at the end of such Interest Period) shall end on the last
Business Day of a calendar month; and

              (c) for purposes of determining the availability of Interest
Periods, such Interest Periods shall be deemed available if (x) Chase Manhattan
Bank quotes an applicable rate or Lender determines LIBOR, as provided in the
definition of LIBOR, (y) LIBOR determined by Chase Manhattan Bank or Lender will
adequately and fairly reflect the cost of maintaining or funding its loans
bearing interest at LIBOR, for such Interest Period, and (z) such Interest
Period will end on or before the last day of the then current Term of this
Agreement. If a requested Interest Period shall be unavailable in accordance
with the foregoing sentence, Borrower shall continue to pay interest on the
Obligations at the applicable per annum rate based upon the rate then applicable
to Prime Rate Loans.

     (e) "LIBOR LOAN" shall mean any loans made pursuant to this Agreement which
are made or maintained at a rate of interest based upon LIBOR, provided that (i)
no Event of Default has occurred hereunder, which has not been waived in writing
by Lender, and (ii) no LIBOR Loan shall be made with an Interest Period that
ends subsequent to the end of a Term or any applicable Early Termination Date.

     (f) "LIBOR" shall mean, at any time of determination, and subject to
availability, for each applicable Interest Period, a variable rate of interest
equal to: (a) the applicable LIBOR quoted to Lender by The Chase Manhattan Bank
(or any successor thereof), or, if unavailable under (a), (b) the rate of
interest determined by Lender at which deposits in U.S. dollars are offered for
the relevant Interest Period based on information presented on Telerate Systems
at Page 3750 as of 11:00 A.M. (London time) on the day which is two (2) Business
Days prior to the first day of such Interest Period, provided that, if at least
two such offered rates appear on the Telerate System at Page 3750 in respect of
such Interest Period, the arithmetic mean of all such rates (as determined by
Lender) will be the rate used; divided by (b) a number equal to 1.0 minus the
aggregate (but without duplication) of the rates (expressed as a decimal
fraction) of Eurocurrency Reserve Requirements in effect on the day which is two
(2) Business Days prior to the beginning of such Interest Period.

     (g) In accordance with Section 3.1(a) hereof, Borrower may request LIBOR
Loans on the following terms and conditions: Borrower may elect, subsequent to
the Closing Date and from time to time thereafter (i) to request any loan made
hereunder to be a LIBOR Loan as of the date of such loan or (ii) to convert
Prime Rate Loans to LIBOR Loans, and may elect from time to time to convert
LIBOR Loans to Prime Rate Loans by giving Lender at least three Business Days'
prior irrevocable notice of such election, provided that any such conversion of
LIBOR Loans to Prime Rate Loans shall only be made, subject to the second
following sentence, on the last day of an Interest Period with respect thereto.
Should Borrower elect to convert Prime Rate Loans to LIBOR Loans, it shall give
Lender at least three Business Days' prior irrevocable notice of such election.
If the last day of an Interest Period with respect to a loan that is to be
converted is not a Business Day, then such conversion shall be made on the next
succeeding Business Day, as the case may be, and during the period from such
last day of an Interest Period to such succeeding Business Day, as the case may
be, such loan shall bear interest as if it were a Prime Rate Loan. All or any
part of outstanding Prime Rate Loans then outstanding with respect to Revolving
Loans may be converted to LIBOR Loans as provided herein, provided that partial
conversions shall be in multiples in an aggregate principal amount of at least
$500,000, with additional increments of $100,000.

     (h) The LIBOR Loans shall bear interest for each Interest Period with
respect thereto on the unpaid principal amount thereof at a rate per annum equal
to LIBOR determined for each Interest Period in accordance with the terms hereof
plus the Applicable LIBOR Margin.

     (i) Interest in respect of the LIBOR Loans shall be calculated on the basis
of a 360-day year and shall be payable as provided in Section 3.1(a) and, in
addition, on the last day of the applicable Interest Period.

                                       -7-

<PAGE>   11

     (j) If any payment on a LIBOR Loan becomes due and payable on a day other
than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day unless the result of such extension would be to extend
such payment into another calendar month in which event such payment shall be
made on the immediately preceding Business Day.

     (k) Borrower may not have more than five (5) facilities which are LIBOR
Loans outstanding at any given time.

     (l) Any LIBOR Loans may be continued as such upon the expiration of an
Interest Period, provided Borrower so notifies Lender, at least three Business
Days' prior to the expiration of said Interest Period, and provided further that
no LIBOR Loan may be continued as such upon the occurrence of any Default or
Event of Default under this Agreement, but shall be automatically converted to a
Prime Rate Loan on the last day of the Interest Period during which occurred
such Default or Event of Default. Absent such notification, LIBOR Loans shall
convert to Prime Rate Loans on the last day of the applicable Interest Period.
Each notice of election, conversion or continuation furnished by Borrower
pursuant hereto shall specify whether such election, conversion or continuation
is for a 30, 60 or 90 day period. Notwithstanding anything to the contrary
contained herein, Lender (or any participant, if applicable) shall not be
required to purchase United States Dollar deposits in the London interbank
market or from any other applicable LIBOR rate market or source or otherwise
"match fund" to fund LIBOR Loans, but any and all provisions hereof relating to
LIBOR Loans shall be deemed to apply as if Lender (and any participant, if
applicable) had purchased such deposits to fund any LIBOR Loans.

     (m) As further set forth in Section 3.6 hereof, in the event that Lender
(or any financial institution which may become a participant hereunder) shall
have determined in the exercise of its reasonable business judgment (which
determination shall be conclusive and binding upon Borrower) that by reason of
circumstances affecting the interbank LIBOR rate market, adequate and reasonable
means do not exist for ascertaining LIBOR applicable for any Interest Period
with respect to (a) a proposed loan that Borrower has requested be made as a
LIBOR Loan, (b) a LIBOR Loan that will result from the requested conversion of a
Prime Rate Loan into a LIBOR Loan or (c) the continuation of LIBOR Loans beyond
the expiration of the then current Interest Period with respect thereto, Lender
shall forthwith give written notice of such determination to Borrower at least
two (2) days prior to, as the case may be, the requested borrowing date for such
LIBOR Loan, the conversion date of such Prime Rate Loan or the last day of such
Interest Period. If such notice is given (i) any requested LIBOR Loan shall be
made as a Prime Rate Loan, (ii) any Prime Rate Loan that was to have been
converted to a LIBOR Loan shall be continued as a Prime Rate Loan, and (iii) any
outstanding LIBOR Loan shall be converted, on the last day of then current
Interest Period with respect thereto, to a Prime Rate Loan. Until such notice
has been withdrawn by Lender, no further LIBOR Loan shall be made nor shall
Borrower have the right to convert a Prime Rate Loan to a LIBOR Loan.

     (n) Notwithstanding any other provisions herein, if any law, regulation,
treaty or directive or any change therein or in the interpretation or
application thereof, shall make it unlawful for Lender to make or maintain LIBOR
Loans as contemplated herein, the then outstanding LIBOR Loans, if any, shall be
converted automatically to Prime Rate Loans on the next succeeding Interest
Payment Date or within such earlier period as required by law. Borrower hereby
agrees promptly to pay Lender, upon its demand, any additional amounts necessary
to compensate Lender for any costs incurred by Lender in making any conversion
in accordance with this Section 3.3(n), including, but not limited to, any
interest or fees payable by Lender to lenders of funds obtained by Lender in
order to make or maintain LIBOR Loans hereunder.

     (o) BORROWER AGREES TO INDEMNIFY AND TO HOLD LENDER (INCLUDING ANY
PARTICIPANT) HARMLESS FROM ANY LOSS OR EXPENSE WHICH LENDER OR SUCH PARTICIPANT
MAY SUSTAIN OR INCUR AS A CONSEQUENCE OF (A) DEFAULT BY BORROWER IN PAYMENT OF
THE PRINCIPAL AMOUNT OF OR INTEREST ON ANY LIBOR LOANS, AS AND WHEN THE SAME
SHALL BE DUE AND PAYABLE IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT,
INCLUDING, BUT NOT LIMITED TO, ANY SUCH LOSS OR EXPENSE ARISING FROM INTEREST OR
FEES PAYABLE BY LENDER OR SUCH PARTICIPANT TO LENDERS OF FUNDS OBTAINED BY
EITHER OF THEM IN ORDER TO

                                       -8-

<PAGE>   12

MAINTAIN THE LIBOR LOANS HEREUNDER, (B) DEFAULT BY BORROWER IN MAKING A
BORROWING OR CONVERSION AFTER BORROWER HAS GIVEN A NOTICE IN ACCORDANCE WITH
SECTION 3.3(G) HEREOF, (C) ANY PREPAYMENT OF LIBOR LOANS ON A DAY WHICH IS NOT
THE LAST DAY OF THE INTEREST PERIOD APPLICABLE THERETO, INCLUDING, WITHOUT
LIMITATION, PREPAYMENTS ARISING AS A RESULT OF THE APPLICATION OF THE PROCEEDS
OF COLLATERAL TO THE REVOLVING LOANS AND (D) DEFAULT BY BORROWER IN MAKING ANY
PREPAYMENT AFTER BORROWER HAD GIVEN NOTICE TO LENDER THEREOF. THE DETERMINATION
BY LENDER OF THE AMOUNT OF ANY SUCH LOSS OR EXPENSE, WHEN SET FORTH IN A WRITTEN
NOTICE TO BORROWER, CONTAINING LENDER'S CALCULATIONS THEREOF IN REASONABLE
DETAIL, SHALL BE CONCLUSIVE ON BORROWER IN THE ABSENCE OF MANIFEST ERROR.
CALCULATION OF ALL AMOUNTS PAYABLE UNDER THIS PARAGRAPH WITH REGARD TO LIBOR
LOANS SHALL BE MADE AS THOUGH LENDER HAD ACTUALLY FUNDED THE LIBOR LOANS THROUGH
THE PURCHASE OF DEPOSITS IN THE RELEVANT MARKET AND CURRENCY, AS THE CASE MAY
BE, BEARING INTEREST AT THE RATE APPLICABLE TO SUCH LIBOR LOANS IN AN AMOUNT
EQUAL TO THE AMOUNT OF THE LIBOR LOANS AND HAVING A MATURITY COMPARABLE TO THE
RELEVANT INTEREST PERIOD PROVIDED, HOWEVER, THAT LENDER MAY FUND EACH OF THE
LIBOR LOANS IN ANY MANNER LENDER SEES FIT AND THE FOREGOING ASSUMPTION SHALL BE
USED ONLY FOR CALCULATION OF AMOUNTS PAYABLE UNDER THIS PARAGRAPH. IN ADDITION,
NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, LENDER SHALL APPLY
ALL PROCEEDS OF COLLATERAL AND ALL OTHER AMOUNTS RECEIVED BY IT FROM OR ON
BEHALF OF BORROWER (I) INITIALLY TO THE PRIME RATE LOANS AND (II) SUBSEQUENTLY
TO LIBOR LOANS; PROVIDED, HOWEVER, (X) UPON THE OCCURRENCE OF AN EVENT OF
DEFAULT OR (Y) IN THE EVENT THE AGGREGATE AMOUNT OF OUTSTANDING LIBOR LOANS
EXCEEDS NET AVAILABILITY OR THE APPLICABLE MAXIMUM LEVELS SET FORTH THEREFOR,
LENDER MAY APPLY ALL SUCH AMOUNTS RECEIVED BY IT TO THE PAYMENT OF OBLIGATIONS
IN SUCH MANNER AND IN SUCH ORDER AS LENDER MAY ELECT IN ITS REASONABLE BUSINESS
JUDGMENT. IN THE EVENT THAT ANY SUCH AMOUNTS ARE APPLIED TO REVOLVING LOANS
WHICH ARE LIBOR LOANS, SUCH APPLICATION SHALL BE TREATED AS A PREPAYMENT OF SUCH
LOANS AND LENDER SHALL BE ENTITLED TO INDEMNIFICATION HEREUNDER. THIS COVENANT
SHALL SURVIVE TERMINATION OF THIS AGREEMENT AND PAYMENT OF THE OUTSTANDING
OBLIGATIONS.

     (p) Notwithstanding anything to the contrary in this Agreement, in the
event that, by reason of any Regulatory Change (for purposes hereof "REGULATORY
CHANGE" shall mean, with respect to Lender, any change after the date of this
Agreement in United States federal, state or foreign law or regulations
(including, without limitation, Regulation D) or the adoption or making after
such date of any interpretation, directive or request applying to a class of
banks including Lender of or under any United States federal, state or foreign
law or regulations (whether or not having the force of law and whether or not
failure to comply therewith would be unlawful), Lender either (a) incurs any
material additional costs based on or measured by the excess above a specified
level of the amount of a category of deposits or other liabilities of such bank
which includes deposits by reference to which the interest rate on LIBOR Loans
is determined as provided in this Agreement or a category of extensions of
credit or other assets of Lender which includes LIBOR Loans or (b) becomes
subject to any material restrictions on the amount of such a category of
liabilities or assets which it may hold, then, if Lender so elects by notice to
Borrower the obligation of Lender to make or continue, or to convert Prime Rate
Loans into LIBOR Loans hereunder shall be suspended until such Regulatory Change
ceases to be in effect.

     (q) If all or a portion of the outstanding principal amount of the
Obligations shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such outstanding amount, to the extent it is a LIBOR
Loan, shall be converted to a Prime Rate Loan at the end of the last Interest
Period therefor.

     (r) Lender shall, at the request of Borrower, deliver to Borrower a
statement showing the quotations given by The Chase Manhattan Bank and the
computations used in determining any interest rate pursuant to Section 3.3
hereof.

     3.4 Fees. Borrower shall pay to Lender:

     (a) Loan Facility Fee. At closing, and at the time of each increment
contemplated in Section 10.3(c) and at the beginning of each three-year renewal
term, a Loan Facility Fee in the amount set forth in Section 10.3(c).

     (b) Commitment Fee. At closing, the balance of a nonrefundable Commitment
Fee in the amount set forth in Section 10.3(d), which shall have been remitted
to Lender in part in the amount set forth in Section 10.3(d) prior to the
Closing Date; provided that the remaining balance of such Commitment Fee paid on
the Closing Date shall be applied to the Loan Facility Fee described in Section
3.4(a).

     (c) Intentionally Omitted.

     (d) Unused Line Fee. Monthly, on the first day of each month, in arrears,
an Unused Line Fee for each month during the initial and each renewal Term at
the rate per annum set forth in Section 10.3(f), calculated upon the amount, if
any, by which the Maximum Credit exceeds the average outstanding daily principal
balance during the preceding month of all Revolving Loans plus each Letter of
Credit.

     (e) Collateral Management Fee. Monthly, on the first day of each month
during the initial and each renewal Term, a Collateral Management Fee for the
immediately preceding month (or part thereof) in the amount set forth in Section
10.3(i).

     (f) Letter of Credit Guaranty Fee. In consideration of the Letter of Credit
Guaranty of Lender, the Letter of Credit Guaranty Fee which shall be an amount
equal to (a) one percent on the face amount of each Letter of Credit payable
upon issuance thereof per annum, payable monthly on the first day of each month
during the initial and each renewal Term.

     (g) Additional Letter of Credit Fees. Any and all charges, fees,
commissions, costs and expenses charged to Lender for Borrower's account by any
Issuing Bank in connection with, or arising out of, Letters of Credit or out of
transactions relating thereto, which will be charged to the Revolving Loan
Account in full when charged to, or paid by Lender, or as may be due upon
any termination of this Agreement hereof, and when made by any such Issuing Bank
shall be conclusive on Lender.

     3.5 Capital Adequacy. In the event that Lender or any participant hereunder
(or any financial institution which may from time to time become a participant
or lender hereunder) shall have determined in the exercise of its reasonable
business judgement that subsequent to the Closing Date any change in applicable
law, rule, regulation or guideline regarding capital adequacy, or any change in
the interpretation or administration thereof, or compliance by Lender or such
participant with any new request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on Lender's or such participant's capital as a consequence of its obligations
hereunder to a level below that which Lender or such participant could have
achieved but for such adoption, change or compliance (taking into consideration
Lender or such participant's policies with respect to capital adequacy) by an
amount reasonably deemed by Lender or such participant to be material, then,
from time to time, Borrower shall pay no later than five days following demand
to Lender or such participant such additional amount or amounts as will
compensate Lender or such participant for such reduction. In determining such
amount or amounts, Lender or such participant may use any reasonable averaging
or attribution methods. The protection of this Section 3.5 shall be available to
Lender or such participant regardless of any possible contention of invalidity
or inapplicability with respect to the applicable law, regulation or condition.
A certificate of Lender or such participant setting forth such amount or amounts
as shall be necessary to compensate Lender or such participant with respect to
this Section 3.5 and the calculation thereof when delivered to Borrower shall be
conclusive on Borrower absent manifest error. Notwithstanding anything in this
paragraph to the contrary, in the event Lender or such participant has exercised
its rights pursuant to this paragraph, and subsequent thereto determines that
the additional amounts paid by Borrower in whole or in part exceed the amount
which Lender or such participant actually required pursuant hereto, the excess,
if any, shall be returned to Borrower by Lender or such participant.

                                      -10-
<PAGE>   14

     3.6 Additional Costs. In the event that any applicable law, treaty or
governmental regulation, or any change therein or in the interpretation or
application thereof, or compliance by Lender or such participant with any
request or directive (whether or not having the force of law) from any central
bank or other financial, monetary or other authority, shall:

     (a) subject Lender or such participant to any tax of any kind whatsoever
with respect to this Agreement or change the basis of taxation of payments to
Lender or such participant of principal, fees, interest or any other amount
payable hereunder or under any other documents (except for changes in the rate
of tax on the overall net income of Lender or such participant by the federal
government or the jurisdiction in which it maintains its principal office);

     (b) impose, modify or hold applicable any reserve, special deposit,
assessment or similar requirement against assets held by, or deposits in or for
the account of, advances or loans by, or other credit extended by Lender or such
participant by reason of or in respect to this Agreement and the Loan Documents,
including (without limitation) pursuant to Regulation D of the Board of
Governors of the Federal Reserve System; or

     (c) impose on Lender or such participant any other condition with respect
to this Agreement or any other document, and the result of any of the foregoing
is to increase the cost to Lender or such participant of making, renewing or
maintaining its loans hereunder by an amount that Lender or such participant
deems to be material in the exercise of its reasonable business judgement or to
reduce the amount of any payment (whether of principal, interest or otherwise)
in respect of any of the loans by an amount that Lender or such participant
deems to be material in the exercise of its reasonable business judgement, then,
in any case Borrower shall pay Lender or such participant, within five (5) days
following its demand, such additional cost or, within thirty (30) days following
its demand, such reduction, as the case may be. Lender or such participant shall
certify the amount of such additional cost or reduced amount to Borrower and the
calculation thereof and such certification shall be conclusive upon Borrower
absent manifest error. Notwithstanding anything in this paragraph to the
contrary, in the event Lender or such participant has exercised its rights
pursuant to this paragraph, and subsequent thereto determine that the additional
amounts paid by Borrower in whole or in part exceed the amount which Lender or
such participant actually required pursuant hereto, the excess, if any, shall be
returned to Borrower by Lender or such participant.

     4.5 Cash and Financial Assets Security. Borrower agrees that upon Lender's
request, it will execute a Pledge Agreement ("PLEDGE AGREEMENT") with respect to
Borrower's deposit account at Chase Bank of Texas, National Association.
Borrower, Chase Bank of Texas, National Association and Lender have executed or
will execute a Tri-Party Control Agreement ("CONTROL AGREEMENT") with respect to
such account.

     4.6 Continuation of Security Interest. The rights and security interests
granted to Lender hereunder are to continue in full force and effect,
notwithstanding the termination of this Agreement or the fact that the Revolving
Loan Account maintained in Borrower's name may from time to time be temporarily
in a credit position, until the final payment in full to Lender of all
Obligations and the termination of this Agreement. Any delay, or omission by
Lender to exercise any right hereunder shall not be deemed a waiver thereof, or
be deemed a waiver of any other right, unless such waiver shall be in writing
and signed by Lender. A waiver on any one occasion shall not be construed as a
bar to, or waiver of, any right or remedy on any future occasion.

     4.7 Election of Remedies. Notwithstanding Lender's security interest in the
Collateral and to the extent that the Obligations are now or hereafter secured
by any assets or property other than the Collateral or by the guarantee,
endorsement, assets or property of any other person, Lender shall have the right
in its sole discretion to determine which rights, liens, security interests or
remedies Lender shall at any time pursue, foreclose upon, relinquish,
subordinate, modify or take any other action with respect to, without in any way
modifying or affecting any of them, or any of Lender's rights hereunder.

     4.8 Credit Balances and Security. Any balances to the credit of Borrower
and any other property or assets of Borrower (now or hereafter acquired) in the
possession or control of Lender may be held by Lender as security for any
Obligations and applied in whole or partial satisfaction of such Obligations
when due. The liens and security interests granted herein, and any other lien or
security interest Lender may have in any other assets of Borrower, shall secure
payment and performance of all now existing and future Obligations. Lender may
in its discretion charge any or all of the Obligations to the Revolving Loan
Account when due.

     4.9 General Intangibles. Borrower possesses all general intangibles and
rights thereto necessary to conduct its business as conducted as of the Closing
Date and Borrower shall maintain its rights in, and the value of, the foregoing
in the ordinary course of its business, including, without limitation, by making
timely payment with respect to any applicable licensed rights. Borrower shall
deliver to Lender, and/or shall cause the appropriate party to deliver to
Lender, from time to time such pledge or security agreements with respect to
general intangibles (now owned or hereafter acquired) of Borrower and its
subsidiaries as Lender shall require to obtain valid first liens thereon. In
furtherance of the foregoing, Borrower shall provide timely notice to Lender of
any additional patents, trademarks, tradenames, service marks, copyrights, brand
names, trade names, logos and other trade designations acquired or applied for
subsequent to the Closing Date and Borrower shall execute such documentation as
Lender may reasonably require to obtain and perfect its lien thereon. Borrower
hereby irrevocably grants to Lender a royalty-free, non-exclusive license in the
general intangibles set forth in Section 4, including tradenames, trademarks,
copyrights, patents, licenses, and any other proprietary and intellectual
property rights and any and all right, title and interest in any of the
foregoing, for the sole purpose, upon the occurrence of an Event of Default, of
the right to: (i) advertise for sale and sell or transfer any inventory bearing
any of the general intangibles, and (ii) make, assemble, prepare for sale or
complete, or cause others to do so, any applicable raw materials or inventory
bearing any of the general intangibles, including use of the equipment for the
purpose of completing the manufacture of unfinished goods, raw materials or
work-in-process comprising inventory, and apply the proceeds thereof to the
Obligations hereunder, all as further set forth in this Agreement and
irrespective of Lender's lien and perfection in any general intangibles.

5.   COLLECTION AND ADMINISTRATION

     5.1 Collections. Borrower will, at its expense as Lender requests, direct
that all remittances and all other proceeds of accounts and other Collateral be
sent to its present lock box unless otherwise approved by Lender, and deposited
into a bank account selected by Lender with arrangements with the bank providing
that all funds deposited in the bank account are to be transferred solely to
Lender. Borrower shall bear all risk of loss of any funds deposited into

                                      -13-
<PAGE>   17

such account. In connection therewith, Borrower shall execute such lock box and
bank account agreements as Lender shall specify. Any collections or other
proceeds received by Borrower shall be held in trust for Lender and immediately
remitted to Lender in kind.

     5.2 Charges to Loan Account. At Lender's option, all payments of principal,
interest, fees, costs, expenses and other charges provided for in this
Agreement, or in any other agreement now or hereafter existing between Lender
and Borrower, may be charged on the date when due, as principal to a loan
account of Borrower maintained by Lender (the "REVOLVING LOAN ACCOUNT").
Interest, fees for the Letter of Credit Guaranty, the Unused Line Fee and any
other amounts payable by Borrower to Lender based on a per annum rate shall be
calculated on the basis of actual days elapsed over a 360-day year.

     5.3 Payments. All Obligations shall be payable at Lender's bank designated
in Section 10.5(b) or at such other bank or place in New York as Lender may
expressly designate from time to time for purposes of this Section. Lender shall
apply all proceeds of accounts or other Collateral received by Lender and all
other payments in respect of the Obligations to the Revolving Loans or to any
other Obligations then due, in whatever order or manner Lender shall determine.
For purposes of determining Gross Availability and Net Availability and for the
calculation of the Minimum Borrowing, remittances and other payments will be
treated as credited to the loan account of Borrower maintained by Lender and
Collateral balances to which they relate, upon the date of Lender's receipt of
advice from Lender's bank that such remittances or other payments have been
credited to Lender's account or in the case of remittances or other payments
received directly in kind by Lender, upon the date of Lender's deposit thereof
at Lender's bank, subject to final payment and collection. In computing interest
charges, the loan account of Borrower will be credited with remittances and
other payments for the number of days set forth in Section 10.3(b) after the day
Lender has received advice of receipt of remittances in Lender's account at
Lender's Bank. For purposes of this Agreement, "BUSINESS DAY" shall mean any day
other than a Saturday, Sunday or any other day on which Lender or banks located
in states where Lender has its offices, are authorized to close.

     5.4 Loan Account Statements. Lender shall render to Borrower monthly a
Revolving Loan Account statement. Each statement shall be considered correct and
binding upon Borrower as an account stated, except to the extent that Lender
receives, within sixty (60) days after the mailing of such statement, written
notice from Borrower of any specific exceptions by Borrower to that statement.

     5.5 Direct Collections. Upon an Event of Default, the Lender may, at any
time, (a) notify any account debtor that the accounts and other Collateral which
includes a monetary obligation have been assigned to Lender by Borrower and that
payment thereof is to be made to the order of and directly to Lender, (b) send,
or cause to be sent by its designee, requests (which may identify the sender by
a pseudonym) for verification by telephone, in writing or otherwise of accounts
and other Collateral directly to any account debtor or any other obligor or any
bailee with respect thereto, (c) demand, collect or enforce payment of any
accounts or such other Collateral, but without any duty to do so, and Lender
shall not be liable for any failure to collect or enforce payment thereof, (d)
take or bring, in the name of Lender or Borrower, all steps, actions, suits or
proceedings deemed by Lender necessary or desirable to effect collection of or
other realization upon the accounts and other Collateral, (e) after an Event of
Default, continuing for thirty (30) days (without any additional grace period
that may be provided by Section 7.2 hereof), change the address for delivery of
mail to Borrower and to receive and open mail addressed to Borrower, and (f)
after an Event of Default, continuing for thirty (30) days (without any
additional grace period that may be provided by Section 7.2 hereof), extend the
time of payment of, compromise or settle for cash, credit, return of
merchandise, and upon any terms or conditions, any and all accounts or other
Collateral which includes a monetary obligation and discharge or release the
account debtor or other obligor, without affecting any of the Obligations. At
Lender's request, all invoices and statements sent to any account debtor, other
obligor or bailee, shall state that the accounts and such other Collateral have
been assigned to Lender and are payable directly and only to Lender.

     5.6 Attorney-in-Fact. Borrower hereby irrevocably appoints Lender as
Borrower's attorney-in-fact and authorizes Lender at Borrower's sole expense, to
exercise at any times in Lender's discretion all or any of the powers

                                      -14-
<PAGE>   18

necessary for Lender to obtain information about the Collateral or to enforce
Lender's rights in accordance with law and with this Agreement.

     5.7 Liability. Borrower hereby releases and exculpates Lender, its officers
and employees from any liability arising from any acts under this Agreement or
in furtherance thereof, except for gross negligence or willful misconduct.
Lender and Borrower will not have any liability to each other for lost profits
or other special or consequential damages.

     5.8 Administration of Accounts. After written notice by Lender to Borrower
or without notice after an Event of Default, within forty-five (45) days
following such written notice or Event of Default, Borrower shall not, outside
of the ordinary course of business: (a) amend, modify, settle or compromise any
of the accounts or any other Collateral which includes a monetary obligation,
(b) release in whole or in part any account debtor or other person liable for
the payment of any of the accounts or any such other Collateral, or (c) grant
any credits, discounts, allowances, deductions, return authorizations or the
like with respect to any of the accounts or any such other Collateral.

     5.9 Documents. Borrower shall reasonably deliver to Lender, as Lender or
Lender's counsel may request, all documents, schedules, invoices, proofs of
delivery, purchase orders, statements, contracts and all other information
evidencing or relating to the Collateral, in form and substance satisfactory to
Lender and duly executed by Borrower. Without limiting the provisions of Section
5.5, Borrower's granting of credits, discounts, allowances, deductions, return
authorizations or the like will be promptly reported to Lender in writing. In no
event shall any schedule or confirmatory assignment (or the absence thereof or
omission of any of the accounts or other Collateral therefrom) limit or in any
way be construed as a waiver, limitation or modification of the security
interests or rights of Lender or the warranties, representations and covenants
of Borrower under this Agreement. Any documents, schedules, invoices or other
paper delivered to Lender by Borrower may be destroyed or otherwise disposed of
by Lender six months after receipt by Lender, unless Borrower requests their
return in writing in advance and makes prior arrangements for their return at
Borrower's expense.

     5.10 Access. Lender shall have access, prior to an Event of Default during
reasonable business hours and on or after an Event of Default at any time, to
all of the premises where Collateral is located for the purposes of inspecting
or copying the Collateral, and all Borrower's books and records. Lender, at no
charge, may use such of Borrower's personnel, equipment, including computer
equipment, programs, printed output and computer readable media, supplies and
premises for the collection of accounts and realization on other Collateral as
Lender, in its sole discretion, deems appropriate. Borrower hereby irrevocably
authorizes all accountants and third parties to disclose and deliver to Lender
at Borrower's expense all financial information, books and records, work papers,
management reports and other information in their possession regarding Borrower.

     5.11 Environmental Audits. From time to time, but not more frequently than
annually (provided Borrower is not in default) as requested by Lender, at the
sole expense of Borrower, Borrower shall provide Lender, or its designee,
complete access to all of Borrower's facilities for the purpose of conducting an
environmental audit of such facilities as Lender may deem necessary.

     6.2 Trade Names. Borrower may from time to time render invoices under its
trade names set forth in Section 10.5(g) and, Borrower represents that: (a) each

Lender of cancellation or reduction of coverage. Lender may obtain at Borrower's
expense, any such insurance should Borrower fail to do so and adjust or settle

faith. Lender may establish Reserves for the amount contested and penalties
which may accrue thereon.

except as reported in writing to Lender, Borrower has no knowledge that any of
the criteria for eligibility are not or are no longer satisfied and the
Eligibility criteria will continue to be satisfied. All statements made and all

     (i) Any petition or application for any relief under the bankruptcy laws of
the United States now or hereafter in effect or under any insolvency,
reorganization, receivership, readjustment of debt, dissolution or liquidation
law or statute of any jurisdiction now or hereafter in effect (whether at law or
in equity) is filed by or against Borrower or any guarantor;

     (j) The indictment of Borrower or any guarantor under any criminal statute,
or commencement of criminal or civil proceedings against Borrower or any
guarantor, pursuant to which statute or proceedings the penalties or remedies
sought or available include forfeiture of any of the property of Borrower or
such guarantor which Lender believes may have a material adverse effect on the
Collateral or Borrower's business;

     (k) Any default or event of default occurs on the part of Borrower under
any material provision of any agreement, document or instrument to which
Borrower is a party or by which Borrower or any of its property is bound;
provided that it shall not be an Event of Default hereunder if Borrower is
contesting in good faith and by appropriate proceedings or action the
determination that such default or event of default has occurred;

     (1) Lender in good faith believes that either (i) the prospect of payment
or performance of the Obligations is impaired or (ii) the Collateral is not
sufficient to secure fully the Obligations; or

     (m) Any material change occurs in the nature or conduct of Borrower's
business.

     7.2 Remedies. Upon the occurrence of an Event of Default, which Event of
Default is continuing for ten (10) days (other than an Event of Default pursuant
to a violation of Section 5.5 hereof), and at any time thereafter, Lender shall
have all rights and remedies provided in this Agreement, any other agreements
between Borrower and Lender, the Uniform Commercial Code and other applicable
law, all of which rights and remedies may be exercised without notice to
Borrower, all such notices being hereby waived, except such notice as is
expressly provided for hereunder or is not waivable under applicable law. All
rights and remedies of Lender are cumulative and not exclusive and are
enforceable, in Lender's discretion, alternatively, successively, or
concurrently on any one or more occasions and in any order Lender may determine.
Without limiting the foregoing, Lender may (a) accelerate the payment of all
Obligations and demand immediate payment thereof to Lender, (b) with or without
judicial process or the aid or assistance of others, enter upon any premises on
or in which any of the Collateral may be located and take possession of the
Collateral or complete processing, manufacturing and repair of all or any
portion of the Collateral, (c) require Borrower, at Borrower's expense, to
assemble and make available to Lender any part or all of the Collateral at any
place and time designated by Lender, (d) collect, foreclose, receive,
appropriate, setoff and realize upon any and all Collateral, (e) sell, lease,
transfer, assign, deliver or otherwise dispose of any and all Collateral
(including, without limitation, entering into contracts with respect thereto, by
public or private sales at any exchange, broker's board, any office of Lender or
elsewhere) (in the case of program inventory, only after an applicable account
debtor's failure to purchase its program inventory at a price acceptable to
Lender), at such prices or terms as Lender may deem reasonable, for cash, upon
credit or for future delivery, with Lender having the right to purchase the
whole or any part of the Collateral at any such public sale, all of the
foregoing being free from any right or equity of redemption of Borrower, which
right or equity of redemption is hereby expressly waived and released by
Borrower. If any of the Collateral is sold or leased by Lender upon credit terms
or for future delivery, the Obligations shall not be reduced as a result thereof
until payment therefor is finally collected by Lender. If notice of disposition
of Collateral is required by law, ten (10) days prior notice by Lender to
Borrower designating the time and place of any public sale or the time after
which any private sale or other intended disposition of Collateral is to be
made, shall be deemed to be reasonable notice thereof and Borrower waives any
other notice. In the event Lender institutes an action to recover any Collateral
or seeks recovery of any Collateral by way of prejudgment remedy, Borrower
waives the posting of any bond which might otherwise be required.

     7.3 Application of Proceeds. Lender may apply the cash proceeds of
Collateral other than accounts actually received by Lender from any sale, lease,
foreclosure or other disposition of the Collateral to payment of any of the
Obligations, in whole or in part and in such order as Lender may elect, whether
or not then due. Borrower shall remain liable to Lender for the payment of any
deficiency together with interest at the highest rate provided for herein and
all costs and expenses of collection or enforcement, including reasonable
attorneys' fees and legal expenses.

     7.4 Lender's Cure of Third Party Agreement Default. Lender may, at its
option, cure any default by Borrower under any agreement with a third party or
pay or bond on appeal any judgment entered against Borrower, discharge taxes,
liens, security interests or other encumbrances at any time levied on or
existing with respect to the Collateral and pay any amount, incur any expense or
perform any act which, in Lender's sole judgment, is necessary or appropriate to
preserve, protect, insure, maintain, or realize upon the Collateral. Lender may
charge Borrower's Revolving Loan Account for any amounts so expended, such
amounts to be repayable by Borrower on demand. Lender shall be under no
obligation to effect such cure, payment, bonding or discharge, and shall not, by
doing so, be deemed to have assumed any obligation or liability of Borrower.

8.   JURY TRIAL WAIVER; CERTAIN OTHER WAIVERS AND CONSENTS

     8.1 JURY TRIAL WAIVER. BORROWER AND LENDER EACH WAIVE ALL RIGHTS TO TRIAL
BY JURY IN ANY ACTION OR PROCEEDING INSTITUTED BY EITHER OF THEM AGAINST THE
OTHER WHICH PERTAINS DIRECTLY OR INDIRECTLY TO THIS AGREEMENT, THE OBLIGATIONS,
THE COLLATERAL, ANY ALLEGED TORTIOUS CONDUCT BY BORROWER OR LENDER, OR, IN ANY
WAY, DIRECTLY OR INDIRECTLY, ARISES OUT OF OR RELATES TO THE RELATIONSHIP
BETWEEN BORROWER AND LENDER. IN NO EVENT WILL LENDER OR BORROWER BE LIABLE FOR
LOST PROFITS OR OTHER SPECIAL OR CONSEQUENTIAL DAMAGES; PROVIDED, HOWEVER, THAT
NOTHING CONTAINED HEREIN SHALL AFFECT THE BORROWER'S OBLIGATION TO PAY ALL
AMOUNTS OWING UNDER THIS AGREEMENT.

     8.2 Counterclaims. Borrower waives all rights to interpose any claims,
deductions, setoffs or counterclaims of any kind, nature or description in any
action or proceeding instituted by Lender with respect to this Agreement, the
Obligations, the Collateral or any matter arising therefrom or relating thereto,
except compulsory counterclaims.

     8.3 Jurisdiction. Borrower hereby irrevocably submits and consents to the
nonexclusive jurisdiction of the State and Federal Courts located in the State
of New York with respect to any action or proceeding arising out of this
Agreement, the Obligations, the Collateral or any matter arising therefrom or
relating thereto. In any such action or proceeding, Borrower waives personal
service of the summons and complaint or other process and papers therein and
agrees that the service thereof may be made by mail directed to Borrower at its
chief executive office set forth herein or other address thereof of which Lender
has received notice as provided herein, service to be deemed complete five (5)
days after mailing, or as permitted under the rules of either of said Courts.
Any such action or proceeding commenced by Borrower against Lender will be
litigated only in a Federal Court located in the district, or a State Court in
the State of New York, in New York County, and Borrower waives any objection
based on FORUM NON CONVENIENS and any objection to venue in connection
therewith.

     8.4 No Waiver by Lender. Lender shall not, by any act, delay, omission or
otherwise be deemed to have expressly or impliedly waived any of its rights or
remedies unless such waiver shall be in writing and signed by an authorized
officer of Lender. A waiver by Lender of any right or remedy on any one occasion
shall not be construed as a bar to or waiver of any such right or remedy which
Lender would otherwise have on any future occasion, whether similar in kind or
otherwise.

9.   TERM OF AGREEMENT; MISCELLANEOUS

     9.1 Term. This Agreement shall only become effective upon execution and
delivery by Borrower and Lender and shall continue in full force and effect for
a term set forth in Section 10.6 from the date hereof and shall be deemed
automatically renewed, based upon all of the terms and provisions of this
Agreement, for successive terms of equal duration thereafter unless terminated
as of the end of the initial or any renewal term (each a "TERM") by either party
giving the other written notice at least sixty (60) days' prior to the end of
the then current Term.

                                      -21-
<PAGE>   25

     9.2 Early Termination. Borrower may also terminate this Agreement by giving
Lender at least thirty (30) days prior written notice and payment in full of all
of the Obligations as provided herein, including the Early Termination Fee set
forth in Section 10.3(h), unpaid and earned Loan Facility Fee and any other fees
then owed to Lender as set forth in the Agreement. Thirty days after receipt of
such early termination notice, Lender need not make any further Revolving Loans.
Lender shall also have the right to terminate this Agreement at any time upon or
after the occurrence of an Event of Default in accordance with Section 7. If
Lender terminates this Agreement upon or after the occurrence of an Event of
Default, Borrower shall pay Lender forthwith, in full, payment in all
Obligations, including Early Termination Fee, unpaid and earned Loan Facility
Fee and any other fees then owed to Lender as set forth in this Agreement. In
view of the impracticality and extreme difficulty of ascertaining actual
damages, the Early Termination Fee shall be in the amounts set forth in Section
10.3(h); provided that Borrower shall not owe such Early Termination Fee if
Borrower refinances the Revolving Loans with the proceeds of a loan made by
Chase Bank or Chase Bank of Texas, N.A. at any time after the first annual
anniversary of the Closing Date.

     9.3 Termination Indemnity Deposit. Upon termination of this Agreement by
Borrower, as permitted herein, in addition to payment of all Obligations which
are not contingent, Borrower shall deposit such amount of cash collateral as
Lender determines is necessary to secure Lender from loss, cost, damage or
expense, including reasonable attorneys' fees, in connection with any open
Letters of Credit and Letter of Credit Guaranties or remittance items or other
payments provisionally credited to the Obligations and/or to which Lender has
not yet received final and indefeasible payment.

     9.4 Notices. Except as otherwise provided, all notices, requests and
demands hereunder shall be (a) made to Lender at its address set forth in
Section 10.5(a) and to Borrower at its chief executive office set forth in
Section 10.5(d), or to such other address as either party may designate by
written notice to the other in accordance with this provision, and (b) deemed to
have been given or made: if by hand, immediately upon delivery; if by telex,
telegram or telescope (fax), immediately upon confirmed receipt; if by overnight
delivery service, one day after dispatch; and if by first class or certified
mail, three (3) days after mailing with confirmed receipt.

     9.5 Severability. If any provision of this Agreement is held to be invalid
or unenforceable, such provision shall not affect this Agreement as a whole, but
this Agreement shall be construed as though it did not contain the particular
provision held to be invalid or unenforceable.

     9.6 Entire Agreement; Amendments; Assignments. This Agreement contains the
entire agreement of the parties as to the subject matter hereof, all prior
commitments, proposals and negotiations concerning the subject matter hereof
being merged herein. Neither this Agreement nor any provision hereof shall be
amended, modified or discharged orally or by course of conduct, but only by a
written agreement signed by an authorized officer of Lender. This Agreement
shall be binding upon and inure to the benefit of each of the parties hereto and
their respective successors and assigns, except that any obligation of Lender
under this Agreement shall not be assignable nor inure to the successors and
assigns of Borrower unless otherwise agreed-to in writing by Lender.

     9.7 Discharge of Borrower. No termination of this Agreement shall relieve
or discharge Borrower of its Obligations, grants of Collateral, duties and
covenants hereunder or otherwise until such time as all Obligations to Lender
have been indefeasibly paid and satisfied in full, including, without
limitation, the continuation and survival in full force and effect of all
security interests and liens of Lender in and upon all then existing and
thereafter-arising or acquired Collateral and all warranties and waivers of
Borrower.

     9.8 Usage. All terms used herein which are defined in the Uniform
Commercial Code shall have the meanings given therein unless otherwise defined
in this Agreement and all references to the singular or plural herein shall also
mean the plural or singular, respectively.

     9.9 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

     9.10 ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REFERRED
TO HEREIN REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND MAY NOT BE
CONTRADICTED OR VARIED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OR DISCUSSIONS OF THE PARTIES HERETO. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS AMONG THE PARTIES HERETO.

     9.11 Maximum Interest. In no event whatsoever shall the aggregate of all
amounts deemed interest hereunder and charged or collected pursuant to the terms
of this Agreement exceed the Maximum Rate, nor shall any provisions hereof be
construed as a contract to pay, for the use, forbearance or detention of money
with interest at a rate or in an amount in excess of the Maximum Rate. If any
provisions of this Agreement contravene any such law, such provisions shall be
deemed amended to conform to such law. Notwithstanding anything to the contrary
contained herein, no provision of this Agreement shall require the payment or
permit the collection of interest in excess of the Maximum Rate. If any excess
of interest in such respect is herein provided for, or shall be adjudicated to
be so provided, in this Agreement or otherwise in connection with this loan
transaction, the provisions of this paragraph shall govern and prevail, and
neither Borrower nor the sureties, guarantors, successors or assigns of Borrower
shall be obligated to pay the excess amount of such interest, or any other
excess sum paid for the use, forbearance or detention of sums loaned pursuant
hereto. If for any reason interest in excess of the Maximum Rate shall be
deemed charged, required or permitted by any court of competent jurisdiction,
any such excess shall be applied as a payment and reduction of the principal of
indebtedness evidenced by this Agreement; and, if the principal amount hereof
has been paid in full, any remaining excess shall forthwith be paid to Borrower.
In determining whether or not the interest paid or payable exceeds the Maximum
Rate, Borrower shall, to the extent permitted by applicable law, (i)
characterize any non-principal payment as an expense, fee, or premium rather
than as interest, (ii) exclude voluntary prepayments and the effects thereof,
and (iii) amortize, prorate, allocate, and spread in equal or unequal parts the
total amount of interest throughout the entire contemplated term of the
indebtedness evidenced by this Agreement so that the interest for the entire
term does not exceed the Maximum Rate.

     (d) GAAP:                        Generally accepted accounting principles
                                      in the United States of America as in
                                      effect from time to time and for the
                                      period as to which such accounting

          THIS FOURTH SUPPLEMENTAL INDENTURE, dated as of ______, 2000 between
Virginia Electric and Power Company, a corporation duly organized and existing
under the laws of the Commonwealth of Virginia (herein called the "Company"),
having its principal office at 701 East Cary Street, Richmond, Virginia 23219-
3932, and The Chase Manhattan Bank, as Trustee, a New York banking corporation
having its principal corporate trust office at 450 West 33rd Street, New York,
New York 10001 (hereinafter called the "Trustee").

                                   RECITALS

          The Company and the Trustee are parties to an Indenture, dated as of
June 1, 1998, as supplemented by a First Supplemental Indenture dated as of June
1, 1998, a Second Supplemental Indenture dated as of June 1, 1999 and a Third
Supplemental Indenture dated as of November 1, 1999 (the "Indenture"), relating
to the issuance from time to time by the Company of its unsecured notes or other
evidences of indebtedness (the "Securities") on terms to be specified at the
time of issuance.  Capitalized terms used herein, not otherwise defined, shall
have the same meanings given them in the Indenture.

          The Company has requested the Trustee to join with it in the execution
and delivery of this fourth supplemental indenture (the "Fourth Supplemental
Indenture") in order to supplement and amend the Indenture, by adding certain
provisions thereof, to permit the Company to require, if it shall so elect, that
Securities of any series created after the date hereof be subject to repayment,
in whole or in part, prior to their Stated Maturity, at the option of Holders
thereof.

          Section 901 of the Indenture provides that a supplemental indenture
may be entered into by the Company and the Trustee, without the consent of any
Holders of Securities to make any provisions with respect to matters or
questions arising under the Indenture, so long as such action does not adversely
affect the interests of the Holders of Securities of any series coupons in any
material respect.

          The Company has determined that this Fourth Supplemental Indenture
complies with Section 901 and does not require the consent of any Holders of
Securities or coupons.

          At the request of the Trustee, the Company has furnished the Trustee
with an Opinion of Counsel complying with the requirements of Section 903 of the
Indenture, stating, among other things, that the execution of this Fourth
Supplemental Indenture is authorized or permitted by the Indenture, and an
Officers' Certificate and Opinion of Counsel complying with the requirements of
Section 102 of the Indenture, and has delivered to the Trustee a Board
Resolution as required by Section 901 of the Indenture authorizing the execution
by the Company of this Fourth Supplemental Indenture and its delivery by the
Company to the Trustee.

                                       1
<PAGE>

          All things necessary to make this Fourth Supplemental Indenture a
valid agreement of the Company and the Trustee, in accordance with the terms of
the Indenture, and a valid amendment of, and supplement to the Indenture have
been done.

          NOW, THEREFORE, THIS FOURTH SUPPLEMENTAL INDENTURE WITNESSETH:

          For and in consideration of the premises, it is mutually covenanted
and agreed, for the equal and proportionate benefit of all Holders of Securities
or coupons, as follows:

I.        AMENDMENTS TO THE INDENTURE

          A.  Section 101 of the Indenture is amended to add a new definition
thereto, in the appropriate alphabetical sequence, as follows:

               "Repayment Date" shall mean, when used with respect to any
                --------------
     Security to be repaid at the option of the Holder, the date fixed for such
     repayment by or pursuant to such Security.

               "Repayment Price" shall mean, when used with respect to any
                ---------------
     Security to be repaid at the option of the Holder, the price at which it is
     to be repaid pursuant to this Indenture.

          B.   Section 113 of the Indenture is hereby deleted and replaced in
its entirety as follows:

               SECTION 113.  Legal Holidays.

               Except as otherwise specified as contemplated by Section 301 with
     regard to a series of Securities, in any case where any Interest Payment
     Date, Redemption Date, Repayment Date or Stated Maturity of any Security
     shall not be a Business Day at any Place of payment, then (notwithstanding
     any other provision of this Indenture or of the Securities or coupons)
     payment of interest or principal (and premium, if any) need not be made at
     such Place of Payment on such date, but may be made on the next succeeding
     Business Day at such Place of Payment with the same force and effect as if
     made on the Interest Payment Date, Redemption Date or Repayment Date or at
     the Stated Maturity, provided that no interest shall accrue on the amount
     so payable for the period from and after such Interest Payment Date,
     Redemption Date, Repayment Date or Stated Maturity, as the case may be.

          C.   Article Two of the Indenture is amended and supplemented to add a
new Section 206, which reads in its entirety as follows:

                                       2
<PAGE>

          Section 206. Securities Repayable at the Option of Holders.

          If the Company shall establish pursuant to Section 301 that the
Securities of a particular series offered in a periodic offering are to be
repaid before their Stated Maturity at the option of Holders thereof, then the
face of such Securities may indicate the applicable Repayment Date(s) and
Repayment Price(s), and such Securities may include the following provisions:

               If so indicated on the face of this Security, the Company may be
          required to repurchase this Security at the option of the Holder, in
          whole or in part, on the Repayment Date(s) and at the applicable
          Repayment Price(s) so indicated on the face hereof, plus accrued
          interest, if any, to the applicable Repayment Date.  On or before the
          applicable Repayment Date, the Company shall deposit with the Trustee
          money sufficient to pay the applicable Repayment Price and any
          interest accrued on the portion of this Security to be tendered for
          repayment.  On and after such Repayment Date, interest will cease to
          accrue on this Security or any portion hereof tendered for repayment.

               The repayment option may be exercised by the Holder of this
          Security for less than the entire principal amount hereof, but in that
          event, the principal amount hereof remaining outstanding after
          repayment must be in an authorized denomination. In the event of
          repurchase of this Security in part only, a new Security or Securities
          of this series and of like tenor for the unpurchased portion hereof
          will be issued in the name of the Holder hereof upon the cancellation
          hereof.

               In order for this Security to be repaid, the Trustee must receive
          at least 30 days but not more than 60 days prior to the Repayment Date
          (i) this Security with the form entitled "Option to Elect Repayment"
          attached to this Security duly completed or (ii) a facsimile
          transmission or a letter from a member of a national securities
          exchange or the National Association of Securities Dealers, Inc. or a
          commercial bank or trust company in the United States setting forth
          the name of the Holder of this Security, the principal amount of this
          Security, the principal amount of this Security to be repaid, the
          certificate number or a description of the tenor and terms of this
          Security, a statement that the option to elect repayment is being
          exercised thereby, and a guarantee that this Security to be repaid,
          together with the duly completed form entitled "Option to Elect
          Repayment" attached to this Security, will be received by the Trustee
          not later than the fifth Business Day after the date of such facsimile
          transmission or letter; however, such facsimile transmission or letter
          shall only be effective if this Security and duly completed form are
          received by the Trustee by such fifth Business Day. Such notice, once
          given, will be irrevocable unless waived by the Company.

                                       3

               Unless otherwise indicated on the face hereof, this Security will
          not be subject to repayment at the option of the Holder.

          D.   SECTION 902(1) of the Indenture is hereby amended (i) to add the
following after the word "redemption" on the third line thereof: "or repayment"
and (ii) to add the following after the words "Redemption Date" in the last line
thereof:  "or, in the case of repayment, on or after the Repayment Date."

          E.   The Indenture is amended and supplemented by adding the following
Article Fifteen:

                                ARTICLE FIFTEEN

                      REPAYMENT AT THE OPTION OF HOLDERS

          Section 1501.  Applicability of Article.

          Repayment of Securities of any series before their Stated Maturity at
the option of Holders thereof shall be made in accordance with the terms of such
Securities and (except as otherwise specified by the terms of such series
established pursuant to Section 301) in accordance with this Article.

          Section 1502.  Repayment of Securities.

          Securities of any series subject to repayment in whole or in part at
the option of the Holders thereof will, unless otherwise provided in the terms
of such Securities, be repaid at a price equal to the principal amount thereof,
together with interest, if any, thereon accrued to the Repayment Date specified
in or pursuant to the terms of such Securities.  The Company covenants that on
or before the Repayment Date it will deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money sufficient to pay the
principal (or, if so provided by the terms of the Securities of any series, a
percentage of the principal) of, and (except if the Repayment Date shall be an
Interest Payment Date) accrued interest on, all the Securities or portions
thereof, as the case may be, to be repaid on such date.

          Section 1503.  Exercise of Option.

          Securities of any series subject to repayment at the option of the
Holders thereof will contain an "Option to Elect Repayment" form on such
Securities.  In order for any Security to be repaid at the option of the Holder,
the Trustee must receive at the Place of Payment therefor specified in the terms
of such Security (or at such other place or places of which the Company shall
from time to time notify the Holders of such Securities) not earlier than 60
days nor later than 30 days prior to the Repayment Date (1) the Security so
providing for such repayment together with the "Option to Elect Repayment" form
duly completed by the Holder (or by the

                                       4
<PAGE>

Holder's attorney duly authorized in writing) or (2) a facsimile transmission or
a letter from a member of a national securities exchange, or the National
Association of Securities Dealers, Inc. ("NASD"), or a commercial bank or trust
company in the United States setting forth the name of the Holder of Security,
the principal amount of the Security, the amount of the Security to be repaid,
the certificate number or a description of the tenor and terms of the Security,
a statement that the option to elect repayment is being exercised thereby and a
guarantee that the Security to be repaid, together with the duly completed form
entitled "Option to Elect Repayment", will be received by the Trustee not later
than the fifth Business Day after the date of such facsimile transmission or
letter; provided, however, that such facsimile transmission or letter shall only
be effective if such Security and form duly completed are received by the
Trustee by such fifth Business Day. If less than the entire principal amount of
such Security is to be repaid in accordance with the terms of such Security, the
principal amount of such Security to be repaid, in increments of the minimum
denomination for Securities of such series, and the denomination or
denominations of the Security or Securities to be issued to the Holder for the
portion of the principal amount of such Security surrendered that is not to be
repaid, must be specified. The principal amount of any Security providing for
repayment at the option of the Holder thereof may not be repaid in part if,
following such repayment, the unpaid principal amount of such Security would be
less than the minimum authorized denomination of Securities of the series of
which such Security to be repaid is a part. Except as otherwise may be provided
by the terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Company.

          Section 1504.  When Securities Presented for Repayment Become Due and
Payable.

          If the Securities of any series providing for repayment at the option
of the Holders thereof shall have been surrendered as provided in this Article
and as provided by or pursuant to the terms of such Securities, such Securities
or the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities so to be repaid shall cease to bear interest.  Upon surrender of any
such Security for repayment in accordance with such provisions, the principal
amount of such Security so to be repaid shall be paid by the Company, together
with accrued interest, if any, to the Repayment Date; provided that,
installments of interest, if any, whose Stated Maturity is on or prior to the
Repayment Date shall be payable (but without interest thereon, unless the
Company shall default in the payment thereof) to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of
business on the relevant Record Dates according to their terms and the
provisions of Section 307.

          If the principal amount of any Security surrendered for repayment
shall not be so repaid upon surrender thereof, such principal amount (together
with interest, if any, thereon accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of interest set forth in
such Security.

          Section 1505.  Securities Repaid in Part.

          Upon surrender of any Security which is to be repaid in part only
(with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder thereof or his attorney duly
authorized in writing), the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge
and at the expense of the Company, a new Security or Securities of the same
series, Stated Maturity and original issue date of any authorized denomination
specified by the Holder, in an aggregate principal amount equal to and in
exchange for the portion of the principal of such Security so surrendered which
is not to be repaid.

          Section 1506.  Compliance with Exchange Act.

          In connection with any repayment of Securities pursuant to this
Article, the Company will comply with the provisions of Rule 13e-4, Rule 14e-1
and any other tender offer rules under the Exchange Act, if required, and will
file Schedule 13E-4 or any other schedule, if required.
