ITEM 5.  OTHER EVENTS.

         On March 8, 1999, HCC Insurance Holdings, Inc. ("HCC") executed a 
Loan Agreement ($150,000,000 Revolving Loan Facility and $100,000,000 Short 
Term Revolving Loan Facility) (the "Facility") with a syndicate of financial 
institutions led by Wells Fargo Bank (Texas), National Association ("Wells 
Fargo") as agent and lender and NationsBank, N.A. as documentation agent and 
lender.  Under the Facility, borrowings may be made from time-to-time by HCC 
for general corporate purposes through the Short Term Revolving Loan Facility 
until the expiration of the Short Term Revolving Loan Facility on March 7, 
2000 and through the Revolving Loan Facility until its expiration on 
February 28, 2002. Outstanding loans under the Facility bear interest at 
HCC's option at rates related to current LIBOR or the announced prime rate of 
Wells Fargo.  The loan is secured in part by the pledge of the stock of 
Avemco Insurance Company, Houston Casualty Company and U.S. Specialty 
Insurance Company, three of HCC's insurance company subsidiaries and by the 
pledge of stock in and guaranties entered into by HCC's principal agency 
subsidiaries.  HCC has made standard affirmative and negative covenants 
consistent with facilities of this type.  The initial funding from the 
Facility will be used, among other things, to refinance existing outstanding 
loans under a $120,000,000 revolving credit facility with Wells Fargo and 
other lenders.

their respective shares of the outstanding Short Term Revolving Loan 
Commitment Percentages until the Short Term Revolving Loan Obligations of 
each Short Term Revolving Loan Lender (including the defaulting Lender) are 
equal to such Lender's Short Term Revolving Loan Commitment Percentage of the 
total Short Term Revolving Loan Obligations.

     2.5  NOTES.  The Revolving Loans made by each Lender shall be evidenced 
by a single Revolving Note of Borrower in substantially the form of EXHIBIT C 
hereto payable to the order of such Lender in a principal amount equal to the 
Revolving Loan Commitment of such Lender, and otherwise duly completed.  The 
Short Term Revolving Loans made by each Lender shall be evidenced by a single 
Short Term Revolving Note of Borrower in substantially the form of EXHIBIT I 
hereto payable to the order of such Lender in a principal amount equal to the 
Short Term Revolving Loan Commitment of such Lender, and otherwise duly 
completed.  Each Lender is hereby authorized by Borrower to endorse on the 
schedule (or a continuation thereof) that may be attached to each Note of 
such Lender, to the extent applicable, the date, amount, type of and the 
applicable period of interest for each Loan made by such Lender to Borrower 
hereunder, and the amount of each payment or prepayment of principal of such 
Loan received by such Lender, PROVIDED, that any failure by such Lender to 
make any such endorsement shall not affect the obligations of Borrower under 
such Note or hereunder in respect of such Loan.

     2.6  USE OF PROCEEDS.  The proceeds of the Loans shall be used to 
refinance existing Borrowed Money Indebtedness of Borrower, to finance 
acquisitions and for other working capital and general corporate purposes. 
Neither Agent nor any Lender shall have any responsibility as to the use of 
any proceeds of the Loans.

3.   BORROWINGS, PAYMENTS, PREPAYMENTS AND INTEREST OPTIONS.

     3.1  BORROWINGS.  Borrower shall give Agent notice of each borrowing to 
be made hereunder as provided in SECTION 4.3 hereof and Agent shall promptly 
notify each Lender of such request.  Not later than 11:00 a.m., San Francisco, 
California time on the date specified for each such borrowing hereunder, each 
Lender shall make available the amount of the Loan, if any, to be made by it 
on such date to Agent at its Principal Office, in immediately available 
funds, for the account of Borrower.  Such amounts received by Agent will be 
held in an account maintained by Borrower with Agent.  The amounts so 
received by Agent shall, subject to the terms and conditions of this 
Agreement, be made available to Borrower by wiring or otherwise transferring, 
in immediately available funds, such amount to an account designated by 
Borrower.

     3.2  PREPAYMENTS.

     (a)  OPTIONAL PREPAYMENTS.  Except as provided in SECTION 3.3 hereof, 
Borrower shall have the right to prepay, on any Business Day, in whole or in 
part, without the payment of any penalty or fee, any Loans at any time or 
from time to time, PROVIDED that Borrower shall give Agent notice of each 
such prepayment as provided in SECTION 4.3 hereof.  Each optional prepayment 
on a Loan shall be in an amount equal to an integral multiple of $500,000 or 
an integral multiple of $100,000 in excess thereof.  Notwithstanding the 
foregoing, no prepayment may be made on the Revolving Loan Obligations unless 
all Short Term Revolving Loan Obligations shall have been paid in full.

     (b)  INTEREST PAYMENTS.  Accrued and unpaid interest on the unpaid 
principal balance of the Loans shall be due and payable (i) on the date of 
any prepayment permitted hereunder and (ii) on the Interest Payment Dates.

     (c)  MANDATORY PREPAYMENTS.  If the Revolving Loan Commitments shall at 
any time be less than the unpaid principal balance of the Revolving Loans, 
Borrower shall make an immediate prepayment on the Revolving Loans equal to 
the difference.  If the Short Term Revolving Loan Commitments shall at any 
time be less than the unpaid principal balance of the Short Term Revolving 
Loans, Borrower shall make an immediate prepayment on the Short Term 
Revolving Loans equal to the difference.

     3.3  INTEREST OPTIONS

     (a)  OPTIONS AVAILABLE.  The outstanding principal balance of the Notes 
shall bear interest at the Base Rate; PROVIDED, that (1) all past due 
amounts, both principal and accrued interest, shall bear interest at the Past 
Due Rate, and (2) subject to the provisions hereof, Borrower shall have the 
option of having all or any portion of the principal balances of the Notes 
from time to time outstanding bear interest at a Eurodollar Rate.  The 
records of Agent and each of the Lenders with respect to Interest Options, 
Interest Periods and the amounts of Loans to which they are applicable shall 
create a rebuttable presumption as to the accuracy thereof, and Agent and 
Lenders agree to furnish written evidence to Borrower upon request of 
Borrower with respect to such matters.  Interest on the Loans shall be 
calculated at the Base Rate except where it is expressly provided pursuant to 


                                       21

<PAGE>

this Agreement that a Eurodollar Rate is to apply.  Interest on the amount of 
each advance against the Notes shall be computed on the amount of that 
advance and from the date it is made. Notwithstanding anything in this 
Agreement to the contrary, for the full term of the Notes the interest rate 
produced by the aggregate of all sums paid or agreed to be paid to the 
holders of the Notes for the use, forbearance or detention of the debt 
evidenced thereby (including all interest on the Notes at the Stated Rate 
plus the Additional Interest) shall not exceed the Ceiling Rate.

     (b)  DESIGNATION AND CONVERSION.  Borrower shall have the right to 
designate or convert its Interest Options in accordance with the provisions 
hereof.  PROVIDED no Event of Default has occurred and is continuing and 
subject to the last sentence of SECTION 3.3(a) and the provisions of 
SECTION 3.3(c), Borrower may elect to have a Eurodollar Rate apply or 
continue to apply to all or any portion of the principal balance of the 
Notes.  Each change in Interest Options shall be a conversion of the rate of 
interest applicable to the specified portion of the Loans, but such 
conversion shall not change the respective outstanding principal balances of 
the Notes.  The Interest Options shall be designated or converted in the 
manner provided below:

     (i)    Borrower shall give Agent telephonic notice, promptly confirmed by a
            Rate Designation Notice (and Agent shall promptly inform each Lender
            thereof).  Each such telephonic and written notice shall specify the
            amount of the Loan and type (i.e. Revolving Loan or Short Term
            Revolving Loan) which is the subject of the designation, if any; the
            amount of borrowings into which such borrowings are to be converted
            or for which an Interest Option is designated; the proposed date for
            the designation or conversion and the Interest Period or Periods, if
            any, selected by Borrower.  Such telephonic notice shall be
            irrevocable and shall be given to Agent no later than the applicable
            Rate Designation Date.

     (ii)   No more than ten (10) LIBOR Borrowings shall be in effect with
            respect to the Loans at any time.

     (iii)  Each designation or conversion of a LIBOR Borrowing shall occur on a
            LIBOR Business Day.

     (iv)   Each request for a LIBOR Borrowing shall be in the amount equal to
            an integral multiple of $2,000,000 or an integral multiple of
            $100,000 in excess thereof.

     (v)    Each designation of an Interest Option with respect to the Revolving
            Notes shall apply to all of the Revolving Notes ratably in
            accordance with their respective outstanding principal balances. 
            Each designation of an Interest Option with respect to the Short
            Term Revolving Notes shall apply to all of the Short Term Revolving
            Notes ratably in accordance with their respective outstanding
            principal balances.  If any Lender assigns an interest in any of its
            Notes when any LIBOR Borrowing is outstanding with respect thereto,
            then such assignee shall have its ratable interest in such LIBOR
            Borrowing.


                                       22

     (c)    SPECIAL PROVISIONS APPLICABLE TO LIBOR BORROWINGS.

     (i)    OPTIONS UNLAWFUL.  If the adoption of any applicable Legal 
Requirement after the Effective Date or any change after the Effective Date 
in any applicable Legal Requirement or in the interpretation or administration 
thereof by any Governmental Authority or compliance by any Lender with any 
request or directive (whether or not having the force of law) issued after 
the Effective Date by any central bank or other Governmental Authority shall 
at any time make it unlawful or impossible for any Lender to permit the 
establishment of or to maintain any LIBOR Borrowing, the commitment of such 
Lender to establish or maintain such LIBOR Borrowing shall forthwith be 
canceled and Borrower shall forthwith, upon demand by Agent to Borrower, 
(1) convert the LIBOR Borrowing of such Lender with respect to which such 
demand was made to a Base Rate Borrowing; (2) pay all accrued and unpaid 
interest to date on the amount so converted; and (3) pay any amounts required 
to compensate each Lender for any additional cost or expense which any Lender 
may incur as a result of such adoption of or change in such Legal Requirement 
or in the interpretation or administration thereof and any Funding Loss which 
any Lender may incur as a result of such conversion.  If, when Agent so 
notifies Borrower, Borrower has given a Rate Designation Notice specifying a 
LIBOR Borrowing but the selected Interest Period has not yet begun, as to the 
applicable Lender such Rate Designation Notice shall be deemed to be of no 
force and effect, as if never made, and the balance of the Loans made by such 
Lender specified in such Rate Designation Notice shall bear interest at the 
Base Rate until a different available Interest Option shall be designated in 
accordance herewith.

     (ii)   INCREASED COST OF BORROWINGS.  If the adoption after the 
Effective Date of any applicable Legal Requirement or any change after the 
Effective Date in any applicable Legal Requirement or in the interpretation 
or administration thereof by any Governmental Authority or compliance by any 
Lender with any request or directive (whether or not having the force of law) 
issued after the Effective Date by any central bank or Governmental Authority 
shall at any time as a result of any portion of the principal balances of the 
Notes being maintained on the basis of a Eurodollar Rate:

            (1)     subject any Lender to any Taxes, or any deduction or
                    withholding for any Taxes, on or from any payment due under
                    any LIBOR Borrowing or other amount due hereunder, other
                    than income and franchise taxes of the United States or its
                    political subdivisions or such other jurisdiction in which
                    the applicable Lender has its principal office or applicable
                    lending office; or

            (2)     change the basis of taxation of payments due from Borrower
                    to any Lender under any LIBOR Borrowing (other than by a
                    change in the rate of taxation of the overall net income of
                    such Lender); or

            (3)     impose, modify, increase or deem applicable any reserve
                    requirement (excluding that portion of any reserve
                    requirement included in the calculation of the applicable
                    Eurodollar Rate), special deposit requirement or similar
                    requirement (including, but not limited to, state law
                    requirements and 


                                       23

<PAGE>

                    Regulation D) against assets of any Lender, or against
                    deposits with any Lender, or against loans made by any
                    Lender, or against any other funds, obligations or other
                    property owned or held by any Lender; or

            (4)     impose on any Lender any other condition regarding any LIBOR
                    Borrowing;

and the result of any of the foregoing is to materially increase the cost to 
any Lender of agreeing to make or of making, renewing or maintaining such 
LIBOR Borrowing, or reduce the amount of principal or interest received by 
any Lender, then, within 15 Business Days after demand by the applicable 
Lender (accompanied by a statement setting forth in reasonable detail the 
applicable Lender's basis therefor), Borrower shall pay to Agent additional 
amounts which shall compensate each Lender for such increased cost or reduced 
amount.  The determination by any Lender of the amount of any such increased 
cost, increased reserve requirement or reduced amount shall create a rebuttable 
presumption as to the accuracy thereof.  Borrower shall have the right, if it 
receives from Agent any notice referred to in this paragraph, upon three 
Business Days' notice to Agent (which shall notify each affected Lender), 
either (i) to repay in full (but not in part) any borrowing with respect to 
which such notice was given, together with any accrued interest thereon, or 
(ii) to convert the LIBOR Borrowing which is the subject of the notice to a 
Base Rate Borrowing; PROVIDED, that any such repayment or conversion shall be 
accompanied by payment of (x) the amount required to compensate each Lender 
for the increased cost or reduced amount referred to in the preceding 
paragraph; (y) all accrued and unpaid interest to date on the amount so 
repaid or converted, and (z) any Funding Loss which any Lender may incur as a 
result of such repayment or conversion.  Each Lender will notify Borrower 
through Agent of any event occurring after the date of this Agreement which 
will entitle such Lender to compensation pursuant to this Section as promptly 
as practicable after it obtains knowledge thereof and determines to request 
such compensation, and (if so requested by Borrower through Agent) will 
designate a different lending office of such Lender for the applicable LIBOR 
Borrowing or will take such other action as Borrower may reasonably request 
if such designation or action is consistent with the internal policy of such 
Lender and legal and regulatory restrictions, will avoid the need for, or 
reduce the amount of, such compensation and will not, in the sole opinion of 
such Lender, be materially disadvantageous to such Lender (PROVIDED that such 
Lender shall have no obligation so to designate a different lending office 
which is located in the United States of America).

     (iii)  INADEQUACY OF PRICING AND RATE DETERMINATION.  If, for any reason 
with respect to any Interest Period, Agent shall have determined (which 
determination shall create a rebuttable presumption as to the accuracy thereof) 
that:

            (1)     Agent is unable through its customary general practices to
                    determine any applicable Eurodollar Rate, or

            (2)     by reason of circumstances affecting the applicable market,
                    generally, Agent is not being offered deposits in United
                    States dollars in such market, for the applicable Interest
                    Period and in an amount equal to the amount of any
                    applicable LIBOR Borrowing requested by Borrower.


                                       24

<PAGE>

then Agent shall give Borrower written notice thereof (accompanied by a 
statement setting forth in reasonable detail the applicable Lender's basis 
therefor) and thereupon, (A) any Rate Designation Notice previously given by 
Borrower designating the applicable LIBOR Borrowing which has not commenced 
as of the date of such notice from Agent shall be deemed for all purposes 
hereof to be of no force and effect, as if never given, and (B) until Agent 
shall notify Borrower that the circumstances giving rise to such notice from 
Agent no longer exist, each Rate Designation Notice requesting the applicable 
Eurodollar Rate shall be deemed a request for a Base Rate Borrowing, and any 
applicable LIBOR Borrowing then outstanding shall be converted, without any 
notice to or from Borrower, upon the termination of the Interest Period then 
in effect with respect to it, to a Base Rate Borrowing.

     (iv)   FUNDING LOSSES.  Borrower shall indemnify each Lender against and 
hold each Lender harmless from any Funding Loss.  This indemnity shall, 
subject to the provisions of SECTION 3.5 hereof, survive the payment of the 
Notes.  A certificate of such Lender (explaining in reasonable detail the 
amount and calculation of the amount claimed) as to any additional amounts 
payable pursuant to this paragraph submitted to Borrower shall create a 
rebuttable presumption as to the accuracy thereof.

     (d)    FUNDING OFFICES; ADJUSTMENTS AUTOMATIC; CALCULATION YEAR.  Any 
Lender may, if it so elects, fulfill its obligation as to any LIBOR Borrowing 
by causing a branch or affiliate of such Lender to make such Loan and may 
transfer and carry such Loan at, to or for the account of any branch office 
or affiliate of such Lender; PROVIDED, that in such event for the purposes of 
this Agreement such Loan shall be deemed to have been made by such Lender and 
the obligation of Borrower to repay such Loan shall nevertheless be to such 
Lender and shall be deemed held by it for the account of such branch or 
affiliate.  Without notice to Borrower or any other Person, each rate required 
to be calculated or determined under this Agreement shall automatically 
fluctuate upward and downward in accordance with the provisions of this 
Agreement.  Interest at the Prime Rate shall be computed on the basis of the 
actual number of days elapsed in a year consisting of 365 or 366 days, as the 
case may be.  All other interest required to be calculated or determined 
under this Agreement shall be computed on the basis of the actual number of 
days elapsed in a year consisting of 360 days, unless the Ceiling Rate would 
thereby be exceeded, in which event, to the extent necessary to avoid 
exceeding the Ceiling Rate, the applicable interest shall be computed on the 
basis of the actual number of days elapsed in the applicable calendar year in 
which accrued.

     (e)    FUNDING SOURCES.  Notwithstanding any provision of this Agreement 
to the contrary, each Lender shall be entitled to fund and maintain its funding 
of all or any part of the Loans in any manner it sees fit, it being understood, 
however, that for the purposes of this Agreement all determinations hereunder 
shall be made as if each Lender had actually funded and maintained each LIBOR 
Borrowing during each Interest Period through the purchase of deposits having 
a maturity corresponding to such Interest Period and bearing an interest rate 
equal to the Eurodollar Rate for such Interest Period.

     3.4    CAPITAL ADEQUACY.  If any Lender shall have determined that the 
adoption after the Effective Date of any applicable law, rule, regulation or 
treaty regarding capital adequacy, or any 


                                       25

<PAGE>

change therein after the Effective Date, or any change in the interpretation 
or administration thereof after the Effective Date by any Governmental 
Authority, central bank or comparable agency charged with the interpretation 
or administration thereof, or compliance by any Lender with any request or 
directive after the Effective Date regarding capital adequacy (whether or not 
having the force of law) of any such Governmental Authority, central bank or 
comparable agency has or would have the effect of reducing the rate of return 
on such Lender's capital as a consequence of its obligations hereunder, under 
the Notes or other Obligations held by it to a level below that which such 
Lender could have achieved but for such adoption, change or compliance by an 
amount deemed by such Lender to be material, then from time to time, upon 
satisfaction of the conditions precedent set forth in this Section, after 
demand by such Lender (with a copy to Agent) as provided below, Borrower 
shall pay (subject to SECTION 11.7 hereof) to such Lender such additional 
amount or amounts as will compensate such Lender for such reduction. The 
certificate of any Lender setting forth such amount or amounts as shall be 
necessary to compensate it and the basis thereof and reasons therefor shall 
be delivered as soon as practicable to Borrower and shall create a rebuttable 
presumption as to the accuracy thereof.  Borrower shall pay the amount shown 
as due on any such certificate within five (5) Business Days after the 
delivery of such certificate.  In preparing such certificate, a Lender may 
employ such assumptions and allocations of costs and expenses as it shall in 
good faith deem reasonable and may use any reasonable averaging and 
attribution method.

     3.5    LIMITATION ON CHARGES; SUBSTITUTE LENDERS; NON-DISCRIMINATION.  
Anything in SECTIONS 3.3 or 3.4 notwithstanding:

            (1)     Borrower shall not be required to pay to any Lender
     reimbursement with regard to any costs or expenses described in such
     Sections, unless such Lender notifies Borrower of such costs or expenses
     within 90 days after the date paid or incurred but in no event more than
     90 days after the repayment of the Loans and the termination of the
     Commitments;

            (2)     none of the Lenders shall be permitted to pass through to
     Borrower charges and costs under such Sections (other than Funding Losses)
     on a discriminatory basis (i.e., which are not also passed through by such
     Lender to all other customers of such Lender similarly situated where such
     customer is subject to documents providing for such pass through); and

            (3)     if any Lender (including, without limitation, the Agent)
     elects to pass through to Borrower any material charge or cost under such
     Sections (other than Funding Losses) or elects to terminate the
     availability of LIBOR Borrowings for any material period of time, Borrower
     may, within 60 days after the date of such event and so long as no Default
     shall have occurred and be continuing, elect to terminate such Lender as a
     party to this Agreement; PROVIDED that, concurrently with such termination
     Borrower shall (i) if Agent and each of the other Lenders shall consent,
     pay that Lender all principal, interest and fees and other amounts owed to
     such Lender through such date of termination or (ii) have arranged for
     another financial institution approved by Agent (such approval not to be
     unreasonably withheld) as of such date, to become a substitute Lender for
     all purposes under this Agreement in the 


                                       26

<PAGE>

     manner provided in SECTION 11.6; PROVIDED FURTHER that, prior to
     substitution for any Lender, Borrower shall have given written notice to
     Agent of such intention and the Lenders shall have the option, but no
     obligation, for a period of 60 days after receipt of such notice, to
     increase their Commitments in order to replace the affected Lender in lieu
     of such substitution.

4.   PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC.

     4.1    PAYMENTS.

     (a)    Except to the extent otherwise provided herein, all payments of 
principal, interest Obligations and other amounts to be made by Borrower 
hereunder, under the Notes and under the other Loan Documents shall be made 
in Dollars, in immediately available funds, to Agent at the Principal Office 
(or in the case of a successor Agent, at the principal office of such successor 
Agent in the United States), not later than 11:00 a.m., San Francisco, 
California time on the date on which such payment shall become due (each such 
payment made after such time on such due date to be deemed to have been made 
on the next succeeding Business Day).

     (b)    Borrower shall, at the time of making each payment hereunder, 
under any Note or under any other Loan Document, specify to Agent the Loans 
or other amounts payable by Borrower hereunder or thereunder to which such 
payment is to be applied.  Each payment received by Agent hereunder, under 
any Note or under any other Loan Document for the account of a Lender shall 
be paid promptly to such Lender, in immediately available funds.  If Agent 
fails to send to any Lender the applicable amount by the close of business on 
the date any such payment is received by Agent if such payment is received 
prior to 11:00 a.m., San Francisco, California time (or on the next succeeding 
Business Day with respect to payments which are received after 11:00 a.m., 
San Francisco, California time), Agent shall pay to the applicable Lender 
interest on such amount from such date at the Federal Funds Rate.  Borrower, 
the Lenders and Agent acknowledge and agree that this provision and each 
other provision of this Agreement or any of the other Loan Documents relating 
to the application of amounts in payment of the Obligations shall be subject 
to the provisions of SECTION 4.2(d) regarding PRO RATA application of amounts 
after an Event of Default shall have occurred and be continuing.

     (c)    If the due date of any payment hereunder or under any Note falls 
on a day which is not a Business Day, the due date for such payments (except 
as otherwise provided in SECTION 3.3 hereof) shall be extended to the next 
succeeding Business Day and interest shall be payable for any principal so 
extended for the period of such extension.

     (d)    All payments by the Borrower hereunder or under any other Loan 
Document shall be made free and clear of and without deduction for or on 
account of any present or future income, stamp, or other taxes, fees, duties, 
withholding or other charges of any nature whatsoever imposed by any taxing 
authority excluding in the case of each Lender taxes imposed on or measured 
by its net income or franchise taxes imposed by the jurisdiction in which it 
is organized or through which it acts for purposes of this Agreement (such 
non-excluded items being hereinafter referred to as 


                                       27

<PAGE>

"TAXES").  If as a result of any change in law (or the interpretation 
thereof) after the date that the applicable Lender became a "Lender" under 
this Agreement any withholding or deduction from any payment to be made to, 
or for the account of, a Lender by the Borrower hereunder or under any other 
Loan Document is required in respect of any Taxes pursuant to any applicable 
law, rule, or regulation, then the Borrower will (i) pay to the relevant 
authority the full amount required to be so withheld or deducted; (ii) to the 
extent available, promptly forward to the Agent an official receipt or other 
documentation reasonably satisfactory to the Agent evidencing such payment to 
such authority; and (iii) pay to the Agent, for the account of each affected 
Lender, such additional amount or amounts as are necessary to ensure that the 
net amount actually received by such Lender will equal the full amount such 
Lender would have received had no such withholding or deduction been 
required.  Each Lender shall determine such additional amount or amounts 
payable to it (which determination shall create a rebuttable presumption as 
to the accuracy thereof), and in such event, Agent shall furnish written 
evidence to Borrower showing how Agent made such determination.  If a Lender 
becomes aware that any such withholding or deduction from any payment to be 
made by the Borrower hereunder or under any other Loan Document is required, 
then such Lender shall promptly notify the Agent and the Borrower thereof 
stating the reasons therefor and the additional amount required to be paid 
under this Section.  Each Lender shall execute and deliver to the Agent and 
Borrower such forms as it may be required to execute and deliver pursuant to 
SECTION 11.13 hereof.  To the extent that any such withholding or deduction 
results from the failure of a Lender to provide a form required by SECTION 11.13
hereof (unless such failure is due to some prohibition under applicable Legal 
Requirements), the Borrower shall have no obligation to pay the additional 
amount required by CLAUSE (iii) above.  Anything in this Section 
notwithstanding, if any Lender elects to require payment by the Borrower of 
any material amount under this Section, the Borrower may, within 60 days 
after the date of receiving notice thereof and so long as no Default shall 
have occurred and be continuing, elect to terminate such Lender as a party to 
this Agreement; PROVIDED that, concurrently with such termination the 
Borrower shall (i) if the Agent and each of the other Lenders shall consent, 
pay that Lender all principal, interest and fees and other amounts owed to 
such Lender through such date of termination or (ii) have arranged for 
another financial institution approved by the Agent (such approval not to be 
unreasonably withheld) as of such date, to become a substitute Lender for all 
purposes under this Agreement in the manner provided in SECTION 11.6; 
PROVIDED FURTHER that, prior to substitution for any Lender, the Borrower 
shall have given written notice to the Agent of such intention and the 
Lenders shall have the option, but no obligation, for a period of 60 days 
after receipt of such notice, to increase their Commitments in order to 
replace the affected Lender in lieu of such substitution.

     4.2    PRO RATA TREATMENT.  Except to the extent otherwise provided

Revolving Loan Lenders in accordance with their respective Revolving Loan 
Commitments and each Short Term Revolving Loan borrowing shall be made 
ratably from the Short Term Revolving Loan Lenders in accordance with their 
respective Short Term Revolving Loan Commitments; (b) each payment of 
commitment fees with respect to the Revolving Loan Commitments and the Short

of the Revolving Loan Lenders or the Short Term Revolving Loan Lenders, as 
the case may be, and each termination or reduction of the Revolving Loan 
Commitments or Short Term Revolving Loan Commitments, as the case may be, 
under SECTION 


                                       28

<PAGE>

2.2 hereof shall be applied, PRO RATA, according to the applicable Lenders' 
respective Revolving Loan Commitments or Short Term Revolving Loan Commitments, 
as the case may be, and (c) each payment by Borrower of principal of or

</TABLE>

Each such notice of termination or reduction shall specify the amount of the 
applicable Commitment to be terminated or reduced.  Each such notice of 
borrowing or prepayment shall specify the amount of the Loans to be borrowed 
or prepaid and the date of borrowing or prepayment (which shall be a Business 
Day). Agent shall promptly notify the affected Lenders of the contents of 
each such notice.  Any selection of a Eurodollar Rate with respect to a Loan 
shall be subject to the advance notice requirements set forth in SECTION 3.3 
hereof.

     4.4    NON-RECEIPT OF FUNDS BY AGENT.  Unless Agent shall have been 
notified by a Lender or Borrower (the "PAYOR") prior to the day on which such 
Lender is to make payment to Agent of the proceeds of a Loan to be made by it 
hereunder or Borrower is to make a payment to Agent for the account of one or 
more of the Lenders, as the case may be (such payment being herein called the 
"REQUIRED PAYMENT"), which notice shall be effective upon receipt, that the 
Payor does not intend to make the Required Payment to Agent, Agent may assume 
that the Required Payment has been made and may, in reliance upon such 
assumption (but shall not be required to), make the amount thereof available 
to the intended recipient on such date and, if the Payor has not in fact made 
the 


                                       29

<PAGE>

Required Payment to Agent, the recipient of such payment shall, on demand, 
pay to Agent the amount made available by Agent, together with interest 
thereon in respect of the period commencing on the date such amount was so 
made available by Agent until the date Agent recovers such amount at a rate 
per annum equal to the Federal Funds Rate for such period.

     4.5    SHARING OF PAYMENTS, ETC.  If a Lender shall obtain payment of 
any principal of or interest on any Loan made by it under this Agreement or 
on any other Obligation then due to such Lender hereunder, through the 
exercise of any right of set-off (including, without limitation, any right of 
setoff or lien granted under SECTION 9.2 hereof), banker's lien, counterclaim 
or similar right, or otherwise, it shall promptly purchase from the other 
Lenders participations in the Loans made or other Obligations held, by the 
other Lenders in such amounts, and make such other adjustments from time to 
time as shall be equitable to the end that all the Lenders shall share the 
benefit of such payment (net of any expenses which may be incurred by such 
Lender in obtaining or preserving such benefit) PRO RATA in accordance with 
the unpaid Obligations then due to each of them (after giving due consideration 
to any similar payments obtained by the other Lenders).  To such end all the 
Lenders shall make appropriate adjustments among themselves (by the resale of 
participations sold or otherwise) if such payment is rescinded or must 
otherwise be restored.  Borrower agrees, to the fullest extent it may 
effectively do so under applicable law, that any Lender so purchasing a 
participation in the Loans made or other Obligations held, by other Lenders 
may exercise all rights of set-off, bankers' lien, counterclaim or similar 
rights with respect to such participation as fully as if such Lender were a 
direct holder of Loans or other Obligations in the amount of such participation.
Nothing contained herein shall require any Lender to exercise any such right 
or shall affect the right of any Lender to exercise, and retain the benefits 
of exercising, any such right with respect to any other indebtedness or 
obligation of Borrower.

5.   CONDITIONS PRECEDENT.

     5.1    INITIAL LOANS.  The obligation of each Lender to make its initial 
Loans hereunder is subject to the following conditions precedent, each of 
which shall have been fulfilled or waived to the satisfaction of Agent:

     (a)    AUTHORIZATION AND STATUS.  Agent shall have received from the 
appropriate Governmental Authorities certified copies of the Organizational 
Documents (other than by-laws) of each Obligor, and evidence satisfactory to 
Agent of all action taken by each Obligor authorizing the execution, delivery 
and performance of the Loan Documents and all other documents related to this 
Agreement to which it is a party (including, without limitation, a certificate 
of the secretary of each such party which is a corporation setting forth the 
resolutions of its Board of Directors authorizing the transactions contemplated 
thereby and attaching a copy of its bylaws), together with such certificates 
as may be appropriate to demonstrate the qualification and good standing of 
and payment of taxes by each Obligor in the jurisdiction of its organization 
and in each other jurisdiction where the failure in which to qualify would 
have a Material Adverse Effect.

     (b)    INCUMBENCY.  Each Obligor shall have delivered to Agent a 
certificate in respect of the name and signature of each of the officers (i) who
is authorized to sign on its behalf the 


                                       30

<PAGE>

applicable Loan Documents related to any Loan and (ii) who will, until 
replaced by another officer or officers duly authorized for that purpose, act 
as its representative for the purposes of signing documents and giving 
notices and other communications in connection with any Loan.  Agent and each 
Lender may conclusively rely on such certificates until they receive notice 
in writing from the applicable Obligor to the contrary.

     (c)    NOTES.  Agent shall have received the appropriate Notes of 
Borrower for each Lender, duly completed and executed.

     (d)    LOAN DOCUMENTS.  Each Obligor shall have duly executed and 
delivered the Loan Documents to which it is a party (in such number of copies 
as Agent shall have requested).  Each such Loan Document shall be in 
substantially the form furnished to the Lenders prior to their execution of 
this Agreement, together with such changes therein as Lenders may approve.

     (e)    SECURITY MATTERS.  All such action as Agent shall have requested 
to perfect the Liens created pursuant to the Security Documents shall have 
been taken, including, without limitation, where applicable, the filing and 
recording of the Security Documents with the appropriate Governmental 
Authorities.  Agent shall also have received evidence satisfactory to it that 
the Liens created by the Security Documents constitute first priority Liens, 
except for the exceptions expressly provided for herein, including, without 
limitation, delivery of all applicable stock certificates (with stock powers 
executed in blank), Uniform Commercial Code search reports and executed 
releases of any prior Liens (except as permitted by SECTION 8.2).

     (f)    FEES AND EXPENSES. Borrower shall have paid to Agent all unpaid 
fees in the amounts previously agreed upon in writing among Borrower and 
Agent; and shall have in addition paid to Agent all amounts payable under 
SECTION 11.3 hereof, on or before the date of this Agreement, except for 
amounts which Agent, in its sole discretion, agrees may be paid at a later 
date.

     (g)    INSURANCE.  Borrower shall have delivered to Agent certificates 
of insurance satisfactory to Agent evidencing the existence of all insurance 
required to be maintained by each Obligor by this Agreement and the Security 
Documents.

     (h)    OPINIONS OF COUNSEL.  Agent shall have received such opinions of 
counsel to Obligors as Agent shall reasonably request with respect to 
Obligors and the Loan Documents.

     (i)    CONSENTS.  Agent shall have received evidence satisfactory to 
Agent that all material consents of each Governmental Authority and of each 
other Person, if any, reasonably required in connection with (a) the Loans 
and (b) the execution, delivery and performance of this Agreement and the 
other Loan Documents have been satisfactorily obtained.

     (j)    PAYMENT OF CERTAIN OUTSTANDING INDEBTEDNESS.  Agent shall have 
received evidence satisfactory to Agent that all existing Borrowed Money 
Indebtedness owing by any Obligors (other than Indebtedness permitted under 
SECTION 8.1 hereof) shall have been paid in full (or will be paid in full out 
of the initial advance hereunder) and that any credit availability under any 
facility for 


                                       31

<PAGE>

Borrowed Money Indebtedness to which any Obligor is a party as the borrower 
(other than Indebtedness permitted under SECTION 8.1 hereof) shall have been 
terminated.

     (k)    OTHER DOCUMENTS.  Agent shall have received such other documents 
consistent with the terms of this Agreement and relating to the transactions 
contemplated hereby as Agent may reasonably request.

     5.2    ALL LOANS.  The obligation of each Lender to make any Loan 
(including the initial Loan) to be made by it hereunder is subject to (a) the 
accuracy, in all material respects, on the date of such Loan of all 
representations and warranties of each Obligor contained in this Agreement 
and the other Loan Documents (except for such representations and warranties 
which expressly refer to a prior date in which case they shall be true and 
correct as of such earlier date); PROVIDED, HOWEVER, that for purposes of 
this Section, in each representation and warranty in ARTICLE 6 hereof that 
makes reference to a Schedule, the representation under this Section that 
such representation and warranty in ARTICLE 6 hereof is true on and as of the 
date of making of such Loan shall take into account subsequent amendments to 
any Schedule referred to therein and matters arising after the date hereof 
which do not otherwise give rise to or constitute a Default hereunder; 
(b) Agent shall have received the following, all of which shall be duly 
executed and in Proper Form: (1) a Request for Extension of Credit as to the 
Loan no later than 9:00 a.m., San Francisco, California time on the Business 
Day on which such Request for Extension of Credit must be given under 
SECTION 4.3 hereof, and (2) such other documents as Agent may reasonably 
require; (c) prior to the making of such Loan and after giving effect 
thereto, there shall have occurred no event having a Material Adverse Effect; 
(d) no Default or Event of Default shall have occurred and be continuing;  
(e) the making of such Loan shall not be illegal or prohibited by any Legal 
Requirement, and (f) Borrower shall have paid all fees and expenses of the 
type described in SECTION 11.3 hereof and all other fees owed to Agent or any 
Lender under the Loan Documents which are due and payable, in each case, 
prior to or on the date of such Loan or such issuance (except for amounts 
which Agent or the applicable Lender, as the case may be, in their sole 
discretion, agree may be paid at a later date).  The submission by the 
Borrower of a Request for Extension of Credit shall be deemed to be a 
representation and warranty that the conditions precedent to the applicable 
Loan have been satisfied.  Selection of a new interest rate at the expiration 
of an Interest Period shall not constitute a new Loan hereunder.

     5.3    SHORT TERM REVOLVING LOANS.  In addition to and cumulative of the 
other conditions precedent set forth in this Section, Borrower shall not be 
entitled to any Short Term Revolving Loan unless there is no current 
availability for further Revolving Loans at the time of the requested Short 
Term Revolving Loan.

6.   REPRESENTATIONS AND WARRANTIES.

     To induce the Lenders to enter into this Agreement and to make the 
Loans, Borrower represents and warrants (such representations and warranties 
to survive any investigation and the making of the Loans) to the Lenders and 
Agent as follows:


                                       32

<PAGE>

     6.1    ORGANIZATION.  Each Obligor (a) is duly incorporated, validly 
existing and in good standing under the laws of the jurisdiction of its 
organization; (b) has all necessary power and authority to conduct its 
business as presently conducted, and (c) is duly qualified to do business and 
in good standing in the jurisdiction of its organization and in all 
jurisdictions in which the failure to so qualify would reasonably be expected 
to have a Material Adverse Effect.

     6.2    FINANCIAL STATEMENTS.  Borrower has furnished to Agent (i) audited 
financial statements (including a balance sheet) as to Borrower which fairly 
present in all material respects, in accordance with GAAP, the consolidated 
financial condition and the results of operations of Borrower as at the end 
of Borrower's fiscal year ending in 1997 and (ii) unaudited financial 
statements (including a balance sheet) as to Borrower which fairly present in 
all material respects, in accordance with GAAP (subject to year-end 
adjustments and the absence of notes), the consolidated financial condition 
and the results of operations of Borrower as at the end of the fiscal quarter 
ended September 30, 1998.  No events, conditions or circumstances have 
occurred from the date that the financial statements were delivered to Agent 
through the Effective Date which would cause said financial statements to be 
misleading in any material respect.  There are no material instruments or 
liabilities which should, in accordance with GAAP, be reflected in such 
financial statements provided to Agent which are not so reflected.

     6.3    ENFORCEABLE OBLIGATIONS; AUTHORIZATION.  The Loan Documents have 
been duly executed and delivered by each applicable Obligor and are legal, 
valid and binding obligations of each applicable Obligor, enforceable in 
accordance with their respective terms, except as may be limited by 
bankruptcy, insolvency and other similar laws and judicial decisions 
affecting creditors' rights generally and by general equitable principles.  
The execution, delivery and performance of the Loan Documents (a) have all 
been duly authorized by all necessary action; (b) are within the power and 
authority of each applicable Obligor; (c) to the best of Borrower's 
knowledge, do not and will not contravene or violate any Legal Requirement 
applicable to any applicable Obligor or the Organizational Documents of any 
applicable Obligor, the contravention or violation of which would reasonably 
be expected to have a Material Adverse Effect; (d) do not and will not result 
in the breach of, or constitute a default under, any material agreement or 
instrument by which any Obligor or any of its Property may be bound the 
contravention or violation of which would reasonably be expected to have a 
Material Adverse Effect, and (e) do not and will not result in the creation 
of any Lien upon any material Property of any Obligor except for Permitted 
Liens.  All necessary permits, registrations and consents for such making and 
performance have been obtained, except where the failure to obtain the same 
would not have a Material Adverse Effect.  Except as otherwise expressly 
stated in the Security Documents, the Liens of the Security Documents will 
constitute valid and perfected first and prior Liens on the Property 
described therein, subject to no other Liens whatsoever except Permitted 
Liens covering Collateral other than equity interests in the Subsidiaries of 
Borrower.

     6.4    OTHER DEBT.  After giving effect to the initial advance hereunder 
(and the payment of certain existing Indebtedness of Obligors thereby), no 
Obligor is in default in the payment of any other Indebtedness or under any 
agreement, mortgage, deed of trust, security agreement or lease to which it 
is a party and which would constitute an Event of Default under SECTION 9.1(b).


                                       33

<PAGE>

     6.5    LITIGATION.  There is no litigation or administrative proceeding, 
to the knowledge of any executive officer of Borrower, pending or threatened 
against, nor any outstanding judgment, order or decree against, Borrower or 
any of its Subsidiaries before or by any Governmental Authority which does or 
would reasonably be expected to have a Material Adverse Effect.  No Obligor 
is in default with respect to any judgment, order or decree of any Governmental 
Authority where such default would have a Material Adverse Effect.

     6.6    TITLE.  Each Obligor has indefeasible title to all of its material 
Property necessary in the ordinary course of its business, free and clear of 
all Liens except Permitted Liens.

     6.7    TAXES.  Each Obligor has filed all federal and other material tax 
returns required to have been filed and paid all federal taxes and all other 
material taxes due and payable, except (i) those for which extensions have 
been obtained and those which are being contested in good faith and adequate 
reserves computed in accordance with GAAP have been set aside therefor and 
(ii) taxes, assessments, levies or other charges imposed by any Governmental 
Authority (other than federal income taxes) with respect to which the failure 
to make payments could not, by reason of the amount thereof or of remedies 
available to such Governmental Authorities, reasonably be expected to have a 
Material Adverse Effect.

     6.8    REGULATIONS U AND X.  None of the proceeds of any Loan will be 
used for the purpose of purchasing or carrying directly or indirectly any 
margin stock or for any other purpose which would constitute this transaction 
a "purpose credit" within the meaning of Regulations U and X of the Board of 
Governors of the Federal Reserve System, as any of them may be amended from 
time to time.

     6.9    SUBSIDIARIES.  As of the Effective Date, Borrower has no 
Subsidiaries other than those set forth on EXHIBIT F hereto.

     6.10   NO UNTRUE OR MISLEADING STATEMENTS.  No representation or 
warranty made by Borrower in any Loan Document or in any document, instrument 
or other writing furnished to the Lenders by or on behalf of any Obligor in 
connection with the transactions contemplated in any Loan Document contains 
any untrue material statement of material fact or omits to state any such 
material fact (of which any executive officer of Borrower has knowledge) 
necessary to make the representations, warranties and other statements 
contained herein or in such other document, instrument or writing not 
misleading in any material respect on the date when made or deemed made.

     6.11   ERISA.  With respect to each Plan, Borrower and each member of 
the Controlled Group have fulfilled their obligations, including obligations 
under the minimum funding standards of ERISA and the Code and are in 
compliance in all material respects with the provisions of ERISA and the 
Code.  No event has occurred which could result in a liability of Borrower or 
any member of the Controlled Group to the PBGC or a Plan (other than to make 
contributions in the ordinary course) that would reasonably be expected to 
have a Material Adverse Effect.  There have not been any nor are there now 
existing any events or conditions that would cause the Lien provided under 
Section 4068 of ERISA to attach to any Property of Borrower or any member of 
the Controlled 


                                       34

<PAGE>

Group. Unfunded Liabilities as of the date hereof do not exceed $500,000.  No 
"prohibited transaction" (for which there is not an exemption) has occurred 
with respect to any Plan.

     6.12   INVESTMENT COMPANY ACT.  No Obligor is an investment company 
within the meaning of the Investment Company Act of 1940, as amended, or, 
directly or indirectly, controlled by or acting on behalf of any Person which 
is an investment company, within the meaning of said Act.

     6.13   PUBLIC UTILITY HOLDING COMPANY ACT.  No Obligor is an "affiliate" 
or a "subsidiary company" of a "public utility company," or a "holding 
company," or an "affiliate" or a "subsidiary company" of a "holding company," 
as such terms are defined in the Public Utility Holding Company Act of 1935, 
as amended.

     6.14   SOLVENCY.  None of Borrower, any other Obligor, or Borrower and 
its Subsidiaries on a consolidated basis, is "insolvent," as such term is 
used and defined in (i) the Bankruptcy Code and (ii) the fraudulent conveyance 
statutes of the State of Texas or of any other applicable jurisdiction.

     6.15   FISCAL YEAR.  The fiscal year of each Obligor ends on December 31.

     6.16   COMPLIANCE.  To the best knowledge of any executive officer of 
Borrower, Borrower and each of its Subsidiaries is in compliance with all 
Legal Requirements applicable to it, except to the extent that the failure to 
comply therewith would not reasonably be expected to have a Material Adverse 
Effect.

     6.17   ENVIRONMENTAL MATTERS. Each Obligor has, to the best knowledge of 
Borrower's executive officers, obtained and maintained in effect all 
Environmental Permits (or the applicable Person has initiated the necessary 
steps to transfer the Environmental Permits into its name or obtain such 
permits), the failure to obtain which would reasonably be expected to have a 
Material Adverse Effect.  Each Obligor and its Properties, business and 
operations have been and are, to the best knowledge of Borrower's executive 
officers, in compliance with all applicable Requirements of Environmental Law 
and Environmental Permits, the failure to comply with which would reasonably 
be expected to have a Material Adverse Effect.  Each Obligor and its 
Properties, business and operations are not, to the best knowledge of 
Borrower's executive officers (after making reasonable inquiry of the 
personnel and records of their respective Corporations), subject to any 
(a) Environmental Claims or (b) Environmental Liabilities, in either case 
direct or contingent, arising from or based upon any act, omission, event, 
condition or circumstance occurring or existing on or prior to the date 
hereof which would reasonably be expected to have a Material Adverse Effect.  
None of the officers of Borrower have received nor is aware of any Obligor 
receiving any notice of any violation or alleged violation of any Requirements 
of Environmental Law or Environmental Permit or any Environmental Claim in 
connection with its Properties, liabilities, condition (financial or otherwise),
business or operations which would reasonably be expected to have a Material 
Adverse Effect.  Borrower does not know of any event or condition with respect 
to currently enacted Requirements of Environmental Laws presently scheduled 
to become effective in the future with respect to any of the Properties of 
any Obligor which would reasonably be expected to have a 


                                       35

<PAGE>

Material Adverse Effect, for which the applicable Person has not made good 
faith provisions in its business plan and projections of financial performance.

     6.18   PROPERTY AND EARNINGS OF MATERIAL SUBSIDIARIES.  The aggregate 
book value of the Property owned by the Material Subsidiaries is equal to or 
greater than ninety percent (90%) of the aggregate consolidated book value of 
the Property owned by Borrower and its Subsidiaries on the Effective Date and 
the aggregate earnings of the Material Subsidiaries for the twelve month 
period ending on the Effective Date is equal to or greater than ninety 
percent (90%) of the aggregate consolidated earnings of Borrower and its 
Subsidiaries for such period.

7.   AFFIRMATIVE COVENANTS.

     Borrower covenants and agrees with Agent and the Lenders that prior to 
the termination of this Agreement it will do or cause to be done, and cause 
each of its Subsidiaries to do or cause to be done, each and all of the 
following:

     7.1    TAXES, EXISTENCE, REGULATIONS, PROPERTY, ETC.  At all times (a) pay 
when due all taxes and governmental charges of every kind upon it or against 
its income, profits or Property, unless and only to the extent that the same 
shall be contested diligently in good faith and adequate reserves in 
accordance with GAAP have been established therefor and, in the case of 
Subsidiaries which are not Obligors, the failure to pay would reasonably be 
expected to have a Material Adverse Effect; (b) do all things necessary to 
preserve its existence, qualifications, rights and franchises in all 
jurisdictions where such failure to qualify would reasonably be expected to 
have a Material Adverse Effect; (c) comply with all applicable Legal 
Requirements (including without limitation Requirements of Environmental Law) 
in respect of the conduct of its business and the ownership of its Property, 
the noncompliance with which would reasonably be expected to have a Material 
Adverse Effect; and (d) cause its Property to be protected, maintained and 
kept in good repair (ordinary wear and tear excepted) and make all replacements 
and additions to such Property as may be reasonably necessary to conduct its 
business properly and efficiently except where the failure to do so would not 
reasonably be expected to have a Material Adverse Effect.

     7.2    FINANCIAL STATEMENTS AND INFORMATION.  Furnish to Agent fifteen (15)
copies of each of the following: (a) as soon as available and in any event
within 100 days after the end of each applicable fiscal year, beginning with the

Borrower; (b) as soon as available and in any event within 60 days after the end

therewith as of the applicable date, all certified and signed by the president,
chief financial officer or treasurer of Borrower (or other authorized officer
approved by Agent) as true and correct in all material respects to the best
knowledge of such officer and, concurrently with the financial statements
provided for in SUBSECTIONS 7.2(a) and (b) hereof commencing with the Annual
Financial Statement prepared as of December 31, 1998, a compliance certificate

requirements, Borrower will fund, or will cause the applicable member of the 
Controlled Group to fund, all current service pension liabilities as they are 
incurred under the provisions of all Plans from time to time in effect, and 
comply with all applicable provisions of ERISA, in each case, except to the

Material Adverse Effect.  Except to the extent that failure to do the same 
would not reasonably be expected to have a Material Adverse Effect, Borrower 
covenants that it shall and shall cause each member of the Controlled Group 
to (1) make contributions to each Plan in accordance with the time limits 
imposed by ERISA and in an amount sufficient to comply with the contribution 
obligations under such Plan and the minimum funding standards requirements of 
ERISA; (2) prepare and file in accordance with the time limits imposed by

limitation, performing a comprehensive review and assessment of all of 
Borrower's and each of its Subsidiaries' systems and adopting a detailed 
plan, with itemized budget, for the remediation, monitoring and testing of 
such systems.  As used herein, "YEAR 2000 COMPLIANT" shall mean, in regard to 
any entity, that all software, hardware, firmware, equipment, goods or 
systems utilized by or material to the business operations or financial 
condition of such entity and the failure of which would reasonably be 
expected to have a Material Adverse Effect, will properly perform date 
sensitive functions before, during and after the year 2000.  Borrower shall 
(and shall cause each of its Subsidiaries to), immediately upon request, 
provide to Agent such certifications or other evidence of Borrower's and its 
Subsidiaries' compliance with the terms hereof as Agent or the Majority 
Lenders may from time to time reasonably require.

creation or acquisition, Borrower shall continue to be in compliance with the 
provisions of SECTION 8.16 hereof); (b) to the extent such Subsidiary 
constitutes an Agency Subsidiary, such Subsidiary shall execute and deliver

Material Subsidiaries for the twelve month period ending on the last day of

Aggregate transfers of Property from Material Subsidiaries which are

and all deposits (general or special, time or demand, provisional or final 
(but excluding the funds held in accounts clearly designated as escrow or 
trust accounts held by Borrower or any other Obligor for the benefit of 
Persons which are not Affiliates of any Obligor, whether or not such setoff 
results in any loss of interest or other penalty, and including without 
limitation all certificates 


                                       48

<PAGE>

of deposit) at any time held, and any other funds or Property at any time 
held, and other Indebtedness at any time owing by such Lender to or for the 
credit or the account of Borrower or any other Obligor against any and all of 
the Obligations irrespective of whether or not such Lender or Agent will have 
made any demand under this Agreement, the Notes or any other Loan Document.  
Should the right of any Lender to realize funds in any manner set forth 
hereinabove be challenged and any application of such funds be reversed, 
whether by court order or otherwise, the Lenders shall make restitution or 
refund to Borrower pro rata in accordance with their Commitments.  Each 
Lender agrees to promptly notify Borrower and Agent after any such setoff and 
application, provided that the failure to give such notice will not affect 
the validity of such setoff and application.  The rights of Agent and the 
Lenders under this Section are in addition to other rights and remedies

Lenders may have.  This Section is subject to the terms and provisions of 
SECTIONS 4.5 and 11.7 hereof.

     9.3    REMEDIES CUMULATIVE.  No remedy, right or power conferred upon 
Agent or any Lender is intended to be exclusive of any other remedy, right or 
power given hereunder or now or hereafter existing at law, in equity, or 
otherwise, and all such remedies, rights and powers shall be cumulative.

10.  AGENT.

     10.1   APPOINTMENT, POWERS AND IMMUNITIES.  Each Lender hereby 
irrevocably appoints and authorizes Agent to act as its agent hereunder and 
under the other Loan Documents with such powers as are specifically delegated 
to Agent by the terms hereof and thereof, together with such other powers as 
are reasonably incidental thereto.  Any Loan Documents executed in favor of 
Agent shall be held by Agent for the ratable benefit of the Lenders. Agent 
("Agent" as used in this SECTION 10 shall include reference to its Affiliates 
and its own and its Affiliates' respective officers, shareholders, directors, 
employees and agents) (a) shall not have any duties or responsibilities 
except those expressly set forth in this Agreement and the other Loan 
Documents, and shall not by reason of this Agreement or any other Loan 
Document be a trustee or fiduciary for any Lender; (b) shall not be 
responsible to any Lender for any recitals, statements, representations or 
warranties contained in this Agreement or any other Loan Document, or in any 
certificate or other document referred to or provided for in, or received by 
any of them under, this Agreement or any other Loan Document, or for the 
value, validity, effectiveness, genuineness, enforceability, execution, 
filing, registration, collectibility, recording, perfection, existence or 
sufficiency of this Agreement or any other Loan Document or any other 
document referred to or provided for herein or therein or any Property 
covered thereby or for any failure by any Obligor or any other Person to 
perform any of its obligations hereunder or thereunder, and shall not have 
any duty to inquire into or pass upon any of the foregoing matters; (c) shall 
not be required to initiate or conduct any litigation or collection 
proceedings hereunder or under any other Loan Document except to the extent 
requested by the Majority Lenders; (d) shall not be responsible for any 
mistake of law or fact or any action taken or omitted to be taken by it 
hereunder or under any other Loan Document or any other document or 
instrument referred to or provided for herein or therein or in connection 
herewith or therewith, including, without limitation, pursuant to its own 
negligence, except for its own gross negligence or willful misconduct; 
(e) shall not be bound by or obliged to recognize any agreement among or 


                                       49

<PAGE>

between Borrower and any Lender to which Agent is not a party, regardless of 
whether Agent has knowledge of the existence of any such agreement or the 
terms and provisions thereof; (f) shall not be charged with notice or 
knowledge of any fact or information not herein set out or provided to Agent 
in accordance with the terms of this Agreement or any other Loan Document; 
(g) shall not be responsible for any delay, error, omission or default of any 
mail, telegraph, cable or wireless agency or operator, and (h) shall not be 
responsible for the acts or edicts of any Governmental Authority.  Agent may 
employ agents and attorneys-in-fact and shall not be responsible for the 
negligence or misconduct of any such agents or attorneys-in-fact selected by 
it with reasonable care.  In any foreclosure proceeding concerning any 
Collateral, each holder of an Obligation if bidding for its own account or 
for its own account and the accounts of other Lenders is prohibited from 
including in the amount of its bid an amount to be applied as a credit 
against the Obligations held by it or the Obligations held by the other 
Lenders; instead, such holder must bid in cash only.  However, in any such 
foreclosure proceeding, Agent may (but shall not be obligated to) submit a 
bid for all Lenders (including itself) in the form of a credit against the 
Obligations, and Agent or its designee may (but shall not be obligated to) 
accept title to such collateral for and on behalf of all Lenders.

     10.2   RELIANCE.  Agent shall be entitled to rely upon any certification, 
notice or other communication (including any thereof by telephone, telex, 
telegram or cable) believed by it to be genuine and correct and to have been 
signed or sent by or on behalf of the proper Person or Persons, and upon 
advice and statements of legal counsel (which may be counsel for Borrower), 
independent accountants and other experts selected by Agent.  Agent shall not 
be required in any way to determine the identity or authority of any Person 
delivering or executing the same.  As to any matters not expressly provided 
for by this Agreement or any other Loan Document, Agent shall in all cases be 
fully protected in acting, or in refraining from acting, hereunder and 
thereunder in accordance with instructions of the Majority Lenders, and any 
action taken or failure to act pursuant thereto shall be binding on all of 
the Lenders. Pursuant to instructions of the requisite Lenders, Agent shall 
have the authority to execute releases of the Security Documents on behalf of 
the Lenders without the joinder of any Lender.  If any order, writ, judgment 
or decree shall be made or entered by any court affecting the rights, duties 
and obligations of Agent under this Agreement or any other Loan Document, 
then and in any of such events Agent is authorized, in its sole discretion, 
to rely upon and comply with such order, writ, judgment or decree which it is 
advised by legal counsel of its own choosing is binding upon it under the 
terms of this Agreement, the relevant Loan Document or otherwise; and if 
Agent complies with any such order, writ, judgment or decree, then it shall 
not be liable to any Lender or to any other Person by reason of such 
compliance even though such order, writ, judgment or decree may be 
subsequently reversed, modified, annulled, set aside or vacated.

     10.3   DEFAULTS.  Agent shall not be deemed to have knowledge of the 
occurrence of a Default (other than the non-payment of principal of or 
interest on Loans) unless Agent has received notice from a Lender or Borrower 
specifying such Default and stating that such notice is a "NOTICE OF 
DEFAULT."  In the event that Agent receives such a Notice of Default, Agent 
shall give prompt notice thereof to the Lenders (and shall give each Lender 
prompt notice of each such non-payment).  Agent shall (subject to SECTION 10.7 
hereof) take such action with respect to such Notice of Default as shall be 
directed by the Majority Lenders and within its rights under the Loan 
Documents and at law or in equity, PROVIDED that, unless and until Agent 
shall have received such directions, Agent 


                                       50

<PAGE>

may (but shall not be obligated to) take such action, or refrain from taking 
such action, permitted hereby with respect to such Notice of Default as it 
shall deem advisable in the best interests of the Lenders and within its 
rights under the Loan Documents, at law or in equity.

     10.4   MATERIAL WRITTEN NOTICES.  In the event that Agent receives any 
written notice of a material nature from the Borrower or any Obligor under 
the Loan Documents, Agent shall promptly inform each of the Lenders thereof.  
Agent shall promptly distribute the financial statements delivered to Agent 
pursuant to SECTION 7.2 hereof and any notices delivered to Agent pursuant to 
SECTION 7.8 hereof.

     10.5   RIGHTS AS A LENDER.  With respect to its Commitments and the 
Loans made, Wells Fargo in its capacity as a Lender hereunder shall have the 
same rights and powers hereunder as any other Lender and may exercise the 
same as though it were not acting in its agency capacity, and the term 
"LENDER" or "LENDERS" shall, unless the context otherwise indicates, include 
Agent in its individual capacity.  Agent may (without having to account 
therefor to any Lender) accept deposits from, lend money to and generally 
engage in any kind of banking, trust, letter of credit, agency or other 
business with Borrower (and any of its Affiliates) as if it were not acting 
as Agent, and Agent may accept fees and other consideration from Borrower (in 
addition to the fees heretofore agreed to between Borrower and Agent) for 
services in connection with this Agreement or otherwise without having to 
account for the same to the Lenders.

     10.6   INDEMNIFICATION.  The Lenders agree to indemnify Agent (to the 
extent not reimbursed under SECTION 11.3 or SECTION 11.4 hereof, but without 
limiting the obligations of Borrower under said SECTIONS 11.3 and 11.4), 
ratably in accordance with the Lenders' respective Commitments, for any and 
all liabilities, obligations, losses, damages, penalties, actions, judgments, 
suits, costs, expenses or disbursements of any kind and nature whatsoever, 
REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE OF ANY 
INDEMNIFIED PARTIES, which may be imposed on, incurred by or asserted against 
Agent in any way relating to or arising out of this Agreement or any other 
Loan Document or any other documents contemplated by or referred to herein or 
therein or the transactions contemplated hereby or thereby (including, 
without limitation, the costs and expenses which Borrower is obligated to pay 
under SECTIONS 11.3 and 11.4 hereof, interest, penalties, attorneys' fees and 
amounts paid in settlement, but excluding, unless a Default has occurred and 
is continuing, normal administrative costs and expenses incident to the 
performance of its agency duties hereunder) or the enforcement of any of the 
terms hereof or thereof or of any such other documents; PROVIDED that no 
Lender shall be liable for any of the foregoing to the extent they arise from 
the gross negligence or willful misconduct of the party to be indemnified.  
The obligations of the Lenders under this SECTION 10.6 shall survive the 
termination of this Agreement and the repayment of the Obligations.

     10.7   NON-RELIANCE ON AGENT AND OTHER LENDERS.  Each Lender agrees that 
it has received current financial information with respect to Borrower and 
each other Obligor that it has, independently and without reliance on Agent 
or any other Lender and based on such documents and information as it has 
deemed appropriate, made its own credit analysis of Borrower and each other 
Obligor and decision to enter into this Agreement and that it will, 
independently and without reliance upon Agent or any other Lender, and based 
on such documents and information as it shall deem 


                                       51

<PAGE>

appropriate at the time, continue to make its own analysis and decisions in 
taking or not taking action under this Agreement or any of the other Loan 
Documents.  Agent shall not be required to keep itself informed as to the 
performance or observance by any Obligor of this Agreement or any of the 
other Loan Documents or any other document referred to or provided for herein 
or therein or to inspect the properties or books of any Obligor. Except for 
notices, reports and other documents and information expressly required to be 
furnished to the Lenders by Agent hereunder or under the other Loan 
Documents, Agent shall not have any duty or responsibility to provide any 
Lender with any credit or other information concerning the affairs, financial 
condition or business of any Obligor (or any of their affiliates) which may 
come into the possession of Agent.

     10.8   FAILURE TO ACT.  Except for action expressly required of Agent 
hereunder or under the other Loan Documents, Agent shall in all cases be 
fully justified in failing or refusing to act hereunder and thereunder unless 
it shall receive further assurances to its satisfaction by the Lenders of 
their indemnification obligations under SECTION 10.6 hereof against any and 
all liability and expense which may be incurred by it by reason of taking or 
continuing to take any such action.

     10.9   RESIGNATION OR REMOVAL OF AGENT.  Subject to the appointment and 
acceptance of a successor Agent as provided below, Agent may resign at any 
time by giving notice thereof to the Lenders and Borrower, and Agent may be 
removed at any time with or without cause by the Majority Lenders; PROVIDED, 
that Agent shall continue as Agent until such time as any successor shall 
have accepted appointment as Agent hereunder.  Upon any such resignation or 
removal, (i) the Majority Lenders without the consent of Borrower shall have 
the right to appoint a successor Agent so long as such successor Agent is 
also a Lender at the time of such appointment and (ii) the Majority Lenders 
shall have the right to appoint a successor Agent that is not a Lender at the 
time of such appointment so long as Borrower consents to such appointment 
(which consent shall not be unreasonably withheld).  If no successor Agent 
shall have been so appointed by the Majority Lenders and accepted such 
appointment within 30 days after the retiring Agent's giving of notice of 
resignation or the Majority Lenders' removal of the retiring Agent, then the 
retiring Agent may, on behalf of the Lenders, appoint a successor Agent.  Any 
successor Agent shall be a bank which has an office in the United States and 
a combined capital and surplus of at least $250,000,000.  Upon the acceptance 
of any appointment as Agent hereunder by a successor Agent, such successor 
Agent shall thereupon succeed to and become vested with all the rights, 
powers, privileges and duties of the retiring Agent and the retiring Agent 
shall be discharged from its duties and obligations hereunder and under any 
other Loan Documents.  Such successor Agent shall promptly specify by notice 
to Borrower its Principal Office referred to in SECTION 3.1 and SECTION 4 
hereof.  After any retiring Agent's resignation or removal hereunder as 
Agent, the provisions of this SECTION 10 shall continue in effect for its 
benefit in respect of any actions taken or omitted to be taken by it while it 
was acting as Agent.

     10.10  NO PARTNERSHIP.  Neither the execution and delivery of this 
Agreement nor any of the other Loan Documents nor any interest the Lenders, 
Agent or any of them may now or hereafter have in all or any part of the 
Obligations shall create or be construed as creating a partnership, joint 
venture or other joint enterprise between the Lenders or among the Lenders 
and Agent.  The relationship between the Lenders, on the one hand, and Agent, 
on the other, is and shall be that of principals and agent only, and nothing 
in this Agreement or any of the other Loan Documents shall 


                                       52

<PAGE>

be construed to constitute Agent as trustee or other fiduciary for any Lender 
or to impose on Agent any duty, responsibility or obligation other than those 
expressly provided for herein and therein.

     10.11  NO WAIVER.  None of the provisions of this Section 10 shall be 
construed as limiting or otherwise waiving any rights or remedies which 
Borrower or any other Obligor may have against Agent or any Lender.

11.  MISCELLANEOUS.

     11.1   WAIVER.  No waiver of any Default or Event of Default shall be a 
waiver of any other Default or Event of Default.  No failure on the part of 
Agent, any Lender or Borrower or any other Obligor to exercise and no delay 
in exercising, and no course of dealing with respect to, any right, power or 
privilege under any Loan Document shall operate as a waiver thereof, nor 
shall any single or partial exercise of any right, power or privilege 
thereunder preclude any other or further exercise thereof or the exercise of 
any other right, power or privilege.  The remedies provided in the Loan 
Documents are cumulative and not exclusive of any remedies provided by law or 
in equity.

     11.2   NOTICES.  All notices and other communications provided for 
herein (including, without limitation, any modifications of, or waivers or 
consents under, this Agreement) shall be given or made by telex, telegraph, 
telecopy (confirmed by mail), cable or other writing and telexed, telecopied, 
telegraphed, cabled, mailed or delivered to the intended recipient at the

Lenders, and each Affiliate thereof and their respective directors, officers,

subject, REGARDLESS OF WHETHER CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE

damages arise out of or result from any (i) actual or proposed use by Borrower 
of the proceeds of any extension of credit by any Lender hereunder; (ii) breach 
by any Obligor of this Agreement or any other Loan Document; (iii) violation

only to the extent, caused by (i) the willful misconduct or gross negligence 
of the party seeking indemnification or (ii) disputes between or among any 
and all of Agent and Lenders.  Nothing in this Section is intended to limit 
the obligations of Borrower under any other provision of this Agreement.

     11.5   AMENDMENTS, ETC.  No amendment or modification of this Agreement, 
the Notes or any other Loan Document shall in any event be effective against 
Borrower unless the same shall be agreed or consented to in writing by

that no amendment, modification, waiver or consent shall, unless in writing

Lender affected thereby, do any of the following:  (a) increase any Commitment 
of any of the Lenders (or reinstate any termination or reduction of the 
Commitments) or subject any of the Lenders to any additional obligations; 
(b) reduce the principal of, or interest on, any Loan or fee hereunder; 
(c) postpone or extend the Revolving Loan Maturity Date, the Revolving Loan 
Termination Date, the Revolving Loan Availability Period, the Short Term

hereof; (d) change the percentage of any of the Commitments or of the aggregate 
unpaid principal amount of any of the Loans, or the percentage of Lenders, 
which shall be required for the Lenders or any of them to take any action 
under this Agreement (including, without limitation, the definition of 
"Majority Lenders"); (e) change any provision contained in SECTIONS 3.4, 11.3 
OR 11.4 hereof or this SECTION 11.5; (f) release any Person from liability 
under a Guaranty or release substantially all of the security for the 
Obligations or release Collateral in any one (1) calendar year ascribed an

not apply to releases which Agent is obligated to provide pursuant to this 
Agreement (including releases required under the definition of "Agency 
Subsidiaries" set forth in SECTION 1.1 hereof) or any of the other Loan 
Documents or by law), or (g) modify the provisions of SECTIONS 4.1(b) or 4.2 
hereof regarding PRO RATA application of amounts after an Event of Default

SECTION 11.5 to the contrary, no amendment, modification, waiver or consent 
shall be made with respect to SECTION 10 without the consent of Agent to the 
extent it affects Agent, as Agent.

     11.6   SUCCESSORS AND ASSIGNS.

     (a)    This Agreement shall be binding upon and inure to the benefit of 
Borrower, Agent and the Lenders and their respective successors and assigns; 
PROVIDED, HOWEVER, that Borrower may not assign or transfer any of its rights 
or obligations hereunder without the prior written consent of all of the 
Lenders, and any such assignment or transfer without such consent shall be 
null and void. Each Lender may sell participations to any Person in all or 
part of any Loan, or all or part of its Notes or Commitments, in which event, 
without limiting the foregoing, the provisions of the Loan Documents shall 
inure to the benefit of each purchaser of a participation; PROVIDED, HOWEVER, 
the PRO RATA treatment of payments, as described in SECTION 4.2 hereof, shall 
be determined as if such Lender had not sold such participation.  Any Lender 
that sells one or more participations to any Person shall not be relieved by 
virtue of such participation from any of its obligations to Borrower under 
this Agreement relating to the Loans.  In the event any Lender shall sell any 
participation, such Lender shall retain the sole right and responsibility to 
enforce the obligations of Borrower relating to the Loans, including, without 
limitation, the right to approve any amendment, modification or waiver of any 
provision of this Agreement other than amendments, modifications or waivers 
with respect to (i) any fees payable hereunder to the Lenders, (ii) the 
amount of principal or the rate of interest payable on, or the dates fixed 
for the scheduled repayment of principal of, the Loans and (iii) the release 
of the Liens on all or substantially all of the Collateral.

     (b)    Each Lender may assign to one or more Lenders or any other Person 
all or a portion of its interests, rights and obligations under this Agreement; 
PROVIDED, HOWEVER, that (i) the aggregate 


                                       55

<PAGE>

amount of the Commitments of the assigning Lender subject to each such 
assignment shall in no event be less than $5,000,000; (ii) other than in the 
case of an assignment to another Lender (that is, at the time of the 
assignment, a party hereto) or to an Affiliate of such Lender or to a Federal 
Reserve Bank, Agent and, so long as no Event of Default shall have occurred 
and be continuing, Borrower must each give its prior written consent, which 
consents shall not be unreasonably withheld, and (iii) the parties to each 
such assignment shall execute and deliver to Agent, for its acceptance an 
Assignment and Acceptance in the form of EXHIBIT D hereto (each an 
"ASSIGNMENT AND ACCEPTANCE") with blanks appropriately completed, together 
with any Note or Notes subject to such assignment and a processing and 
recording fee of $3,000 paid by the assignee (for which Borrower will have no 
liability). Upon such execution, delivery and acceptance, from and after the 
effective date specified in each Assignment and Acceptance, (A) the assignee 
thereunder shall be a party hereto and, to the extent provided in such 
Assignment and Acceptance, have the rights and obligations of a Lender 
hereunder and (B) the Lender thereunder shall, to the extent provided in such 
Assignment and Acceptance, be released from its obligations under this 
Agreement (and, in the case of an Assignment and Acceptance covering all or 
the remaining portion of an assigning Lender's rights and obligations under 
this Agreement, such Lender shall cease to be a party hereto except in 
respect of provisions of this Agreement which survive payment of the 
Obligations and termination of the Commitments). Notwithstanding anything 
contained in this Agreement to the contrary, any Lender may at any time 
assign all or any portion of its rights under this Agreement and the Notes 
issued to it as collateral to a Federal Reserve Bank; provided that no such 
assignment shall release such Lender from any of its obligations hereunder.

     (c)    By executing and delivering an Assignment and Acceptance, the 
Lender assignor thereunder and the assignee thereunder confirm to and agree 
with each other and the other parties hereto as follows:  (i) other than the 
representation and warranty that it is the legal and beneficial owner of the 
interest being assigned thereby free and clear of any adverse claim, such 
Lender assignor makes no representation or warranty and assumes no 
responsibility with respect to any statements, warranties or representations 
made in or in connection with this Agreement or any of the other Loan 
Documents or the execution, legality, validity, enforceability, genuineness, 
sufficiency or value of this Agreement or any of the other Loan Documents or 
any other instrument or document furnished pursuant thereto; (ii) such Lender 
assignor makes no representation or warranty and assumes no responsibility 
with respect to the financial condition of Borrower or the performance or 
observance by Borrower of any of its obligations under this Agreement or any 
of the other Loan Documents or any other instrument or document furnished 
pursuant hereto; (iii) such assignee confirms that it has received a copy of 
this Agreement, together with copies of the financial statements referred to 
in SECTION 6.2 hereof and such other documents and information as it has 
deemed appropriate to make its own credit analysis and decision to enter into 
such Assignment and Acceptance; (iv) such assignee will, independently and 
without reliance upon Agent, such Lender assignor or any other Lender and 
based on such documents and information as it shall deem appropriate at the 
time, continue to make its own credit decisions in taking or not taking 
action under this Agreement and the other Loan Documents; (v) such assignee 
appoints and authorizes Agent to take such action as agent on its behalf and 
to exercise such powers under this Agreement and the other Loan Documents as 
are delegated to Agent by the terms hereof, together with such powers as are 
reasonably incidental thereto; and (vi) such assignee agrees that it will 
perform in accordance 


                                       56

<PAGE>

with their terms all obligations that by the terms of this Agreement and the 
other Loan Documents are required to be performed by it as a Lender.

     (d)    The entries in the records of Agent as to each Assignment and 
Acceptance delivered to it and the names and addresses of the Lenders and the 
Commitments of, and principal amount of the Loans owing to, each Lender from 
time to time shall create a rebuttable presumption as to the accuracy thereof 
and Borrower, Agent and the Lenders may treat each Person the name of which 
is recorded in the books and records of Agent as a Lender hereunder for all 
purposes of this Agreement and the other Loan Documents.

     (e)    Upon Agent's receipt of an Assignment and Acceptance executed by 
an assigning Lender and the assignee thereunder, together with any Note or 
Notes subject to such assignment and the written consent to such assignment 
(to the extent consent is required), Agent shall, if such Assignment and 
Acceptance has been completed with blanks appropriately filled, (i) accept 
such Assignment and Acceptance, (ii) record the information contained therein 
in its records and (iii) give prompt notice thereof to Borrower.  Within 
fifteen (15) Business Days after receipt of notice (and provided that Borrower 
has consented to the applicable assignment to the extent Borrower's consent 
is required with respect thereto), Borrower, at its own expense (but without 
incurring any expense or cost incurred by Agent or any Lender), shall execute 
and deliver to Agent in exchange for the surrendered Notes new Notes to the 
order of such assignee in an amount equal to the respective Commitments assumed 
by it pursuant to such Assignment and Acceptance and, if the assigning Lender 
has retained Commitments hereunder, new Notes to the order of the assigning 
Lender in an amount equal to the respective Commitments retained by it 
hereunder.  Such new Notes shall be in an aggregate principal amount equal to 
the aggregate principal amount of such surrendered Notes, shall be dated the 
effective date of such Assignment and Acceptance and shall otherwise be in 
substantially the form of the respective Note.  Thereafter, such surrendered 
Notes shall be marked renewed and substituted and the originals thereof 
delivered to Borrower (with copies, certified by Borrower as true, correct 
and complete, to be retained by Agent).

     (f)    Any Lender may, in connection with any assignment or participation 
or proposed assignment or participation pursuant to this SECTION 11.6, disclose 
to the assignee or participant or proposed assignee or participant, any 
information relating to Borrower furnished to such Lender by or on behalf of 
Borrower.

     11.7   LIMITATION OF INTEREST.  Borrower and the Lenders intend to 
strictly comply with all applicable federal and Texas laws, including 
applicable usury laws (or the usury laws of any jurisdiction whose usury laws 
are deemed to apply to the Notes or any other Loan Documents despite the 
intention and desire of the parties to apply the usury laws of the State of 
Texas).  Accordingly, the provisions of this SECTION 11.7 shall govern and 
control over every other provision of this Agreement or any other Loan 
Document which conflicts or is inconsistent with this Section, even if such 
provision declares that it controls.  As used in this Section, the term 
"interest" includes the aggregate of all charges, fees, benefits or other 
compensation which constitute interest under applicable law, PROVIDED that, 
to the maximum extent permitted by applicable law, (a) any non-principal 
payment shall be characterized as an expense or as compensation for something 
other than the use, forbearance or detention of money and not as interest, 
and (b) all interest at any time 


                                       57

<PAGE>

contracted for, reserved, charged or received shall be amortized, prorated, 
allocated and spread, in equal parts during the full term of the Obligations. 
In no event shall Borrower or any other Person be obligated to pay, or any 
Lender have any right or privilege to reserve, receive or retain, (a) any 
interest in excess of the maximum amount of nonusurious interest permitted 
under the laws of the State of Texas or the applicable laws (if any) of the 
United States or of any other jurisdiction, or (b) total interest in excess 
of the amount which such Lender could lawfully have contracted for, reserved, 
received, retained or charged had the interest been calculated for the full 
term of the Obligations at the Ceiling Rate.  The daily interest rates to be 
used in calculating interest at the Ceiling Rate shall be determined by 
dividing the applicable Ceiling Rate per annum by the number of days in the 
calendar year for which such calculation is being made.  None of the terms 
and provisions contained in this Agreement or in any other Loan Document 
(including, without limitation, SECTION 9.1 hereof) which directly or 
indirectly relate to interest shall ever be construed without reference to 
this SECTION 11.7, or be construed to create a contract to pay for the use, 
forbearance or detention of money at an interest rate in excess of the 
Ceiling Rate.  If the term of any Obligation is shortened by reason of 
acceleration of maturity as a result of any Default or by any other cause, or 
by reason of any required or permitted prepayment, and if for that (or any 
other) reason any Lender at any time, including but not limited to, the 
stated maturity, is owed or receives (and/or has received) interest in excess 
of interest calculated at the Ceiling Rate, then and in any such event all of 
any such excess interest shall be canceled automatically as of the date of 
such acceleration, prepayment or other event which produces the excess, and, 
if such excess interest has been paid to such Lender, it shall be credited 
PRO TANTO against the then-outstanding principal balance of Borrower's 
obligations to such Lender, effective as of the date or dates when the event 
occurs which causes it to be excess interest, until such excess is exhausted 
or all of such principal has been fully paid and satisfied, whichever occurs 
first, and any remaining balance of such excess shall be promptly refunded to 
its payor.

     11.8   SURVIVAL.  The obligations of Borrower under SECTIONS 3.3, 3.4, 
11.3 AND 11.4 hereof and all other obligations of Borrower in any other Loan 
Document (to the extent stated therein as surviving) and the obligations of 
the Lenders under SECTION 10.5 and 11.7 hereof, shall, notwithstanding anything 
herein to the contrary, survive the repayment of the Loans and the termination 
of the Commitments.

     11.9   CAPTIONS.  Captions and section headings appearing herein are 
included solely for convenience of reference and are not intended to affect 
the interpretation of any provision of this Agreement.

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

     11.11  GOVERNING LAW.  THIS AGREEMENT AND (EXCEPT AS THEREIN PROVIDED) 
THE OTHER LOAN DOCUMENTS SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE 
WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF 
AMERICA FROM TIME TO TIME IN EFFECT.


                                       58

     11.12  SEVERABILITY.  Whenever possible, each provision of the Loan
Documents shall be interpreted in such manner as to be effective and valid under
applicable law.  If any provision of any Loan Document shall be invalid, illegal
or unenforceable in any respect under any applicable law, the validity, legality
and enforceability of the remaining provisions of such Loan Document shall not
be affected or impaired thereby.

     11.13  TAX FORMS.  Each Lender which is organized under the laws of a
jurisdiction outside the United States shall, on the day of the initial
borrowing from each such Lender hereunder and from time to time thereafter if
requested by Borrower or Agent, provide Agent and Borrower with the forms
prescribed by the Internal Revenue Service of the United States certifying as to
such Lender's status for purposes of determining exemption from United States
withholding taxes with respect to all payments to be made to such Lender
hereunder or other documents satisfactory to such Lender, Borrower and Agent
indicating that all payments to be made to such Lender hereunder are not subject
to United States withholding tax or are subject to such tax at a rate reduced by
an applicable tax treaty.  Unless Borrower and Agent shall have received such
forms or such documents indicating that payments hereunder are not subject to
United States withholding tax or are subject to such tax at a rate reduced by an
applicable tax treaty, Borrower or Agent shall withhold taxes from such payments
at the applicable statutory rate.

     11.14  VENUE.  The Borrower hereby irrevocably (a) agrees that any legal
proceeding against the Agent or any Lender arising out of or in connection with
the Loan Documents shall be brought in the district courts of Harris County,
Texas, or in the United States District Court for the Southern District of
Texas, Houston Division (collectively, the "HOUSTON COURTS"); (b) submits to the
non-exclusive jurisdiction of the Houston Courts; (c) agrees and consents that
service of process may be made upon it in any proceeding arising out of the Loan
Documents or any transaction contemplated thereby by service of process as
provided by Texas law; (d) WAIVES, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of any Loan Document or the transactions
contemplated thereby in the Houston Courts; and (e) WAIVES any claim that any
such suit, action or proceeding in any Houston Court has been brought in an
inconvenient forum.  All of the obligations of the Borrower under the Loan
Documents are performable in Harris County, Texas.  Nothing herein shall affect
the right of the Agent or any Lender to commence legal proceedings or otherwise
proceed against the Borrower in any jurisdiction or to serve process in any
manner permitted by applicable law.  The Borrower agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions in any manner provided by law.

     11.15  JURY WAIVER.  BORROWER, AGENT AND LENDERS EACH WAIVE ANY RIGHT TO
HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT,
TORT OR OTHERWISE ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO
THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS.  INSTEAD, ANY DISPUTES RESOLVED IN COURT WILL BE
RESOLVED IN A BENCH TRIAL WITHOUT A JURY.


                                   59
<PAGE>

     11.16  CONFLICTS BETWEEN THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.  In
the event of any conflict between the terms of this Agreement and the terms of
any of the other Loan Documents, the terms of this Agreement shall control.

     11.17  DISCLOSURE TO OTHER PERSONS; CONFIDENTIALITY.  Agent and each Lender
agree that it may deliver copies of any financial statements and other documents
or information delivered to it and disclose any other information disclosed to
it by or on behalf of Borrower or any Subsidiary of Borrower in connection with
or pursuant to this Agreement and the other Loan Documents only to:

            (i)     its and its affiliates' directors, officers, employees,
     auditors, attorneys and professional consultants;

            (ii)    any other Lender;

            (iii)   any Person to which such Lender offers to sell its Note or
     any part thereof, provided that each such Person agrees in writing to
     observe the confidentiality standards described in this Section;

            (iv)    any Person to which such Lender sells or offers to sell a
     participation in all or any part of its Note, PROVIDED that each such
     Person agrees in writing to observe the confidentiality standards described
     in this Section;

            (v)     any federal or state regulatory authority having
     jurisdiction over it;

            (vi)    any other Person to which such delivery or disclosure may be
     legally required in response to any subpoena or other legal process or
     investigative demand (in which event the Agent or the applicable Lender, as
     the case may be, shall, unless prohibited by applicable law, notify
     Borrower as soon as practicable), and 

            (vii)   any other Person in connection with any litigation involving
     any obligation, right or remedy of Agent or any Lender under the Loan
     Documents.

Subject to the foregoing, Agent and each Lender hereby agrees to use its best
efforts to hold in confidence and not to disclose any Confidential Information;
PROVIDED, that such Person will be free, after notice to Borrower, to correct
any false or misleading information which may become public concerning its
relationship to Borrower.  For the purpose of this Section, the term 
"CONFIDENTIAL INFORMATION" shall mean information about Borrower or any
Subsidiary of Borrower furnished by Borrower or any such Subsidiary, but does
not include any information which (i) is publicly known, or otherwise known to
such holder, at the time of disclosure; (ii) subsequently becomes publicly
known, but not through any act or omission by such holder, or (iii) otherwise
becomes known to such holder other than through disclosure by Borrower or any
Subsidiary of Borrower from any Person which is not known to be subject to a
confidentiality agreement with Borrower or the applicable Subsidiary of
Borrower.

Dollars ($_____________) (or the unpaid balance of all principal advanced 
against this note, if that amount is less), together with interest on the 
unpaid principal balance of this note from time to time outstanding at the 
rate or rates provided in that certain Loan Agreement (as amended,

dated as of March ____, 1999 among Maker, certain signatory banks named 
therein, NationsBank, N.A., as Documentation Agent, and Wells Fargo Bank 
(Texas), National Association, as Agent; PROVIDED, that for the full term of 
this note the interest rate produced by the aggregate of all sums paid or 
agreed to be paid to the holder of this note for the use, forbearance or 
detention of the debt evidenced hereby (including, but not limited to, all 
interest on this note at the Stated Rate plus the Additional Interest) shall 
not exceed the Ceiling Rate.  Any term defined in the Loan Agreement which is 
used in this note and which is not otherwise defined in this note shall have 
the meaning ascribed to it in the Loan Agreement.

     1.     LOAN AGREEMENT; ADVANCES; SECURITY.  This note has been issued
pursuant to the terms of the Loan Agreement, and is one of the Revolving Notes
referred to in the Loan Agreement.  Advances against this note by Payee or other
holder hereof shall be governed by the terms and provisions of the Loan
Agreement.  Reference is hereby made to the Loan Agreement for all purposes. 
Payee is entitled to the benefits of and security provided for in the Loan
Agreement.  The unpaid principal balance of this note at any time shall be the
total of all amounts lent or advanced against this note less the amount of all
payments or  prepayments made on this note and by or for the account of Maker. 
All Loans and advances and all payments and  prepayments made hereon may be
endorsed by the holder of this note on a schedule which may be attached hereto
(and thereby made a part hereof for all purposes) or otherwise recorded in the
holder's records; PROVIDED, that any failure to make notation of (a) any Loan or
advance shall not cancel, limit or otherwise affect Maker's obligations or any
holder's rights with respect to that Loan or advance, or (b) any payment or 
prepayment of principal shall not cancel, limit or otherwise affect Maker's
entitlement to credit for that payment as of the date received by the holder.


                                   EXHIBIT C
                               to Loan Agreement
                                      -1-

<PAGE>

     2.     MANDATORY PAYMENTS OF PRINCIPAL AND INTEREST.

     (a)    Accrued and unpaid interest on the unpaid principal balance of this
note shall be due and payable on the Interest Payment Dates.

     (b)    On the Revolving Loan Maturity Date, the entire unpaid principal
balance of this note and all accrued and unpaid interest on the unpaid principal
balance of this note shall be finally due and payable.

     (c)    All payments hereon made pursuant to this Paragraph shall be applied
first to accrued interest, the balance to principal.

     (d)    The Loan Agreement provides for required prepayments of the
indebtedness evidenced hereby upon terms and conditions specified therein.

     3.     NO USURY INTENDED; SPREADING.  Notwithstanding any provision to the
contrary contained in this note or any of the other Loan Documents, it is
expressly provided that in no case or event shall the aggregate of (a) all
interest on the unpaid balance of this note, accrued or paid from the date
hereof and (b) the aggregate of any Additional Interest, ever exceed the Ceiling
Rate.  In this connection, Maker and Payee stipulate and agree that it is their
common and overriding intent to contract in strict compliance with applicable
federal and Texas usury laws (and the usury laws of any other jurisdiction whose
usury laws are deemed to apply to this note or any of the other Loan Documents
despite the intention and desire of the parties to apply the usury laws of the
State of Texas).  In furtherance thereof, none of the terms of this note or any
of the other Loan Documents shall ever be construed to create a contract to pay,
as consideration for the use, forbearance or detention of money, interest at a
rate in excess of the Ceiling Rate.  Maker or other parties now or hereafter
becoming liable for payment of the indebtedness evidenced by this note shall
never be liable for interest in excess of the Ceiling Rate.  If, for any reason
whatever, the interest paid or received on this note during its full term
produces a rate which exceeds the Ceiling Rate, the holder of this note shall
credit against the principal of this note (or, if such indebtedness shall have
been paid in full, shall refund to the payor of such interest) such portion of
said interest as shall be necessary to cause the interest paid on this note to
produce a rate equal to the Ceiling Rate.  All sums paid or agreed to be paid to
the holder of this note for the use, forbearance or detention of the
indebtedness evidenced hereby shall, to the extent permitted by applicable law,
be amortized, prorated, allocated and spread in equal parts throughout the full
term of this note, so that the interest rate is uniform throughout the full term
of this note.  The provisions of this Paragraph shall control all agreements,
whether now or hereafter existing and whether written or oral, between Maker and
Payee.

     4.     DEFAULT.  The Loan Agreement provides for the acceleration of the
maturity of this note and other rights and remedies upon the occurrence of
certain events specified therein.


                                   EXHIBIT C
                               to Loan Agreement
                                      -2-

<PAGE>

     5.     WAIVERS BY MAKER AND OTHERS.  Except to the extent, if any, that
notice of default is expressly required herein or in any of the other Loan
Documents, Maker and any and all co-makers, endorsers, guarantors and sureties
severally waive notice (including, but not limited to, notice of intent to
accelerate and notice of acceleration, notice of protest and notice of
dishonor), demand, presentment for payment, protest, diligence in collecting and
the filing of suit for the purpose of fixing liability and consent that the time
of payment hereof may be extended and re-extended from time to time without
notice to any of them.  Each such Person agrees that its liability on or with
respect to this note shall not be affected by any release of or change in any
guaranty or security at any time existing or by any failure to perfect or to
maintain perfection of any lien against or security interest in any such
security or the partial or complete unenforceability of any guaranty or other
surety obligation, in each case in whole or in part, with or without notice and
before or after maturity.

     6.     PARAGRAPH HEADINGS.  Paragraph headings appearing in this note are
for convenient reference only and shall not be used to interpret or limit the
meaning of any provision of this note.

     7.     CHOICE OF LAW.  THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES
OF AMERICA FROM TIME TO TIME IN EFFECT.

     8.     SUCCESSORS AND ASSIGNS.  This note and all the covenants and
agreements contained herein shall be binding upon, and shall inure to the
benefit of, the respective legal representatives, heirs, successors and assigns
of Maker and Payee.

     9.     RECORDS OF PAYMENTS.  The records of Payee shall be prima facie
evidence of the amounts owing on this note.

     10.    SEVERABILITY.  If any provision of this note is held to be illegal,
invalid or unenforceable under present or future laws, the legality, validity
and enforceability of the remaining provisions of this note shall not be
affected thereby, and this note shall be liberally construed so as to carry out
the intent of the parties to it.

     11.    REVOLVING LOAN.  Subject to the terms and provisions of the Loan
Agreement, Maker may use all or any part of the credit provided to be evidenced
by this note at any time before the Revolving Loan Maturity Date.  Maker may
borrow, repay and reborrow hereunder; and except as set forth in the Loan
Agreement there is no limitation on the number of advances made hereunder. 
Maker and Payee agree pursuant to Chapter 346 ("CHAPTER 346") of the Texas
Finance Code, that Chapter 346 (which relates to open-end line of credit
revolving loan accounts) shall not apply to this note or any Loan evidenced
hereby and that neither this note nor any Loan evidenced hereby shall be
governed by Chapter 346 or subject to its provisions in any manner whatsoever.

     12.    BUSINESS LOANS.  Maker warrants and represents to Payee and all

Chapter 1D.

                              SHORT TERM REVOLVING NOTE

                                    Houston, Texas
$__________                                            ______________, 199__ 


     FOR VALUE RECEIVED, HCC INSURANCE HOLDINGS, INC., a Delaware corporation 
("MAKER"), promises to pay to the order of _______________________ ("PAYEE"), 
at the principal office of Wells Fargo Bank (Texas), National Association, a 
national banking association, Syndications Dept., 201 3rd Street, 8th Floor, 
San Francisco, California 94103, in immediately available funds and in lawful 
money of the United States of America, the principal sum of ________________ 
Dollars ($_____________) (or the unpaid balance of all principal advanced 
against this note, if that amount is less), together with interest on the 
unpaid principal balance of this note from time to time outstanding at the 
rate or rates provided in that certain Loan Agreement (as amended, 
supplemented, restated or replaced from time to time, the "LOAN AGREEMENT") 
dated as of March ____, 1999 among Maker, certain signatory banks named 
therein, NationsBank, N.A., as Documentation Agent, and Wells Fargo Bank 
(Texas), National Association, as Agent; PROVIDED, that for the full term of 
this note the interest rate produced by the aggregate of all sums paid or 
agreed to be paid to the holder of this note for the use, forbearance or 
detention of the debt evidenced hereby (including, but not limited to, all 
interest on this note at the Stated Rate plus the Additional Interest) shall 
not exceed the Ceiling Rate.  Any term defined in the Loan Agreement which is 
used in this note and which is not otherwise defined in this note shall have 
the meaning ascribed to it in the Loan Agreement.

     1.     LOAN AGREEMENT; ADVANCES; SECURITY.  This note has been issued
pursuant to the terms of the Loan Agreement, and is one of the Short Term
Revolving Notes referred to in the Loan Agreement.  Advances against this note
by Payee or other holder hereof shall be governed by the terms and provisions of
the Loan Agreement.  Reference is hereby made to the Loan Agreement for all
purposes.  Payee is entitled to the benefits of and security provided for in the
Loan Agreement.  The unpaid principal balance of this note at any time shall be
the total of all amounts lent or advanced against this note less the amount of
all payments or  prepayments made on this note and by or for the account of
Maker.  All Loans and advances and all payments and  prepayments made hereon may
be endorsed by the holder of this note on a schedule which may be attached
hereto (and thereby made a part hereof for all purposes) or otherwise recorded
in the holder's records; PROVIDED, that any failure to make notation of (a) any
Loan or advance shall not cancel, limit or otherwise affect Maker's obligations
or any holder's rights with respect to that Loan or advance, or (b) any payment
or  prepayment of principal shall not cancel, limit or otherwise affect Maker's
entitlement to credit for that payment as of the date received by the holder.


                                   EXHIBIT I
                               to Loan Agreement
                                      -1-

<PAGE>

     2.     MANDATORY PAYMENTS OF PRINCIPAL AND INTEREST.

     (a)    Accrued and unpaid interest on the unpaid principal balance of this
note shall be due and payable on the Interest Payment Dates.

     (b)    On the Short Term Revolving Loan Maturity Date, the entire unpaid
principal balance of this note and all accrued and unpaid interest on the unpaid
principal balance of this note shall be finally due and payable.

     (c)    All payments hereon made pursuant to this Paragraph shall be applied
first to accrued interest, the balance to principal.

     (d)    The Loan Agreement provides for required prepayments of the
indebtedness evidenced hereby upon terms and conditions specified therein.

     3.     NO USURY INTENDED; SPREADING.  Notwithstanding any provision to the
contrary contained in this note or any of the other Loan Documents, it is
expressly provided that in no case or event shall the aggregate of (a) all
interest on the unpaid balance of this note, accrued or paid from the date
hereof and (b) the aggregate of any Additional Interest, ever exceed the Ceiling
Rate.  In this connection, Maker and Payee stipulate and agree that it is their
common and overriding intent to contract in strict compliance with applicable
federal and Texas usury laws (and the usury laws of any other jurisdiction whose
usury laws are deemed to apply to this note or any of the other Loan Documents
despite the intention and desire of the parties to apply the usury laws of the
State of Texas).  In furtherance thereof, none of the terms of this note or any
of the other Loan Documents shall ever be construed to create a contract to pay,
as consideration for the use, forbearance or detention of money, interest at a
rate in excess of the Ceiling Rate.  Maker or other parties now or hereafter
becoming liable for payment of the indebtedness evidenced by this note shall
never be liable for interest in excess of the Ceiling Rate.  If, for any reason
whatever, the interest paid or received on this note during its full term
produces a rate which exceeds the Ceiling Rate, the holder of this note shall
credit against the principal of this note (or, if such indebtedness shall have
been paid in full, shall refund to the payor of such interest) such portion of
said interest as shall be necessary to cause the interest paid on this note to
produce a rate equal to the Ceiling Rate.  All sums paid or agreed to be paid to
the holder of this note for the use, forbearance or detention of the
indebtedness evidenced hereby shall, to the extent permitted by applicable law,
be amortized, prorated, allocated and spread in equal parts throughout the full
term of this note, so that the interest rate is uniform throughout the full term
of this note.  The provisions of this Paragraph shall control all agreements,
whether now or hereafter existing and whether written or oral, between Maker and
Payee.

     4.     DEFAULT.  The Loan Agreement provides for the acceleration of the
maturity of this note and other rights and remedies upon the occurrence of
certain events specified therein.


                                   EXHIBIT I
                               to Loan Agreement
                                      -2-

<PAGE>

     5.     WAIVERS BY MAKER AND OTHERS.  Except to the extent, if any, that
notice of default is expressly required herein or in any of the other Loan
Documents, Maker and any and all co-makers, endorsers, guarantors and sureties
severally waive notice (including, but not limited to, notice of intent to
accelerate and notice of acceleration, notice of protest and notice of
dishonor), demand, presentment for payment, protest, diligence in collecting and
the filing of suit for the purpose of fixing liability and consent that the time
of payment hereof may be extended and re-extended from time to time without
notice to any of them.  Each such Person agrees that its liability on or with
respect to this note shall not be affected by any release of or change in any
guaranty or security at any time existing or by any failure to perfect or to
maintain perfection of any lien against or security interest in any such
security or the partial or complete unenforceability of any guaranty or other
surety obligation, in each case in whole or in part, with or without notice and
before or after maturity.

     6.     PARAGRAPH HEADINGS.  Paragraph headings appearing in this note are
for convenient reference only and shall not be used to interpret or limit the
meaning of any provision of this note.

     7.     CHOICE OF LAW.  THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES
OF AMERICA FROM TIME TO TIME IN EFFECT.

     8.     SUCCESSORS AND ASSIGNS.  This note and all the covenants and
agreements contained herein shall be binding upon, and shall inure to the
benefit of, the respective legal representatives, heirs, successors and assigns
of Maker and Payee.

     9.     RECORDS OF PAYMENTS.  The records of Payee shall be prima facie
evidence of the amounts owing on this note.

     10.    SEVERABILITY.  If any provision of this note is held to be illegal,
invalid or unenforceable under present or future laws, the legality, validity
and enforceability of the remaining provisions of this note shall not be
affected thereby, and this note shall be liberally construed so as to carry out
the intent of the parties to it.

     11.    REVOLVING LOAN.  Subject to the terms and provisions of the Loan
Agreement, Maker may use all or any part of the credit provided to be evidenced
by this note at any time before the Short Term Revolving Loan Maturity Date. 
Maker may borrow, repay and reborrow hereunder; and except as set forth in the
Loan Agreement there is no limitation on the number of advances made hereunder. 
Maker and Payee agree pursuant to Chapter 346 ("CHAPTER 346") of the Texas
Finance Code, that Chapter 346 (which relates to open-end line of credit
revolving loan accounts) shall not apply to this note or any Loan evidenced
hereby and that neither this note nor any Loan evidenced hereby shall be
governed by Chapter 346 or subject to its provisions in any manner whatsoever.


                                   EXHIBIT I
                               to Loan Agreement
                                      -3-

<PAGE>

     12.    BUSINESS LOANS.  Maker warrants and represents to Payee and all
other holders of this note that all loans evidenced by this note are and will be
for business, commercial, investment or other similar purpose and not primarily
for personal, family, household or agricultural use, as such terms are used in
Chapter 1D.

     13.    ARBITRATION.  Reference is hereby made to SECTION 11.14 of the 
Loan Agreement providing for arbitration. The provisions of such Section are 
hereby incorporated herein by this reference.
