</TABLE>
         "Total Leverage Ratio" is defined as the ratio of Borrower's Total
         Indebtedness to Consolidated Annualized EBITDA.

         "Consolidated Annualized EBITDA" is defined as Borrower's Consolidated
         EBITDA as calculated on an annualized basis whereby (i) through the
         quarterly period ending June 30, 2001, Consolidated EBITDA for the
         subject fiscal quarter shall be multiplied by four, and (ii) beginning
         with the quarterly period ending September 30, 2001, Consolidated
         EBITDA for the four fiscal quarters through and including the subject
         fiscal quarter shall be summed.

                                       2
<PAGE>

         "Consolidated EBITDA" is defined as the sum of Borrower's (i)
         consolidated net income, (ii) consolidated interest expense, (iii)
         accrued consolidated federal and state income taxes payable which are
         included in the determination of consolidated net income, and (iv)
         consolidated depreciation and amortization.

         "Total Indebtedness" is defined as all obligations for borrowed money,
         including all obligations owed pursuant to this Agreement, Subordinated
         Debt, guarantees, stand-by letters of credit, capitalized leases, and
         other loans. Total Indebtedness excludes all preferred stock and
         preferred stock dividends.

         The Bank will determine the Applicable Term Loan Prime Rate Margin and
         the Applicable Term Loan LIBOR Rate Margin for each fiscal quarter on
         the forty-fifth (45th) day following the last day of each quarter of
         the immediately preceding fiscal quarter by reference to the Compliance
         Certificate delivered to the Bank by the Borrower pursuant to Section
         4.5(c) of this Agreement. If Bank has not received the Compliance
         Certificate by the forty-fifth (45th) day as required, the Applicable
         Term Loan C Prime Rate Margin will be 3.50% and any LIBOR balances may
         be converted to the Prime Rate plus the Applicable Term Loan C Prime
         Rate Margin at Bank's discretion. The Total Leverage Ratio for the
         immediately preceding fiscal quarter must meet the above referenced
         thresholds for any decrease in the Applicable Term Loan C LIBOR Rate
         Margin and the Applicable Term Loan C Prime Rate Margin to occur.

             (2) LIBOR ADDENDUM. The LIBOR Addendum attached to the Term Loan C
         Note shall set forth additional terms relating to LIBOR Rate loans.

(d)          TERM LOAN C NOTE. The payment terms, maturity date, and certain
other terms of the Term Loan C will be contained in a promissory note dated
the date of this agreement ("Term Loan C Note"), as such may be amended or
replaced from time to time.

time to time and in such amounts as Borrower shall request up to an aggregate
principal amount outstanding not to exceed:

             (1) Eighty percent (80%) of Eligible Accounts, plus

             (2) Fifty percent (50%) of Eligible Inventory, not to exceed One
         Million Dollars ($1,000,000);

as such Eligible Accounts and Eligible Inventory may be adjusted from time to
time as provided for under Section 4.15 hereof (the "Borrowing Base"), and in no
event more than Seven Million Dollars ($7,000,000) (the "ABL Line of Credit").

the ABL Loan Account (as defined below) is greater than the lesser of: (x) the
Borrowing Base or (y) the ABL Line of Credit,

                                       3

Borrower shall immediately pay to Bank, in cash, the amount of such excess.
Any commitment of Bank, pursuant to the terms of this Agreement, to make ABL
Loans shall expire on the ABL Maturity Date (as hereinafter defined), subject

Provided that no Event of Default (as hereinafter defined) has occurred and
is continuing, all or any portion of the ABL Loans advanced by Bank which are
repaid by Borrower shall be available for reborrowing in accordance with the
terms hereof. Borrower promises to pay to Bank the entire outstanding unpaid

Account on the earlier of demand by Bank or May 31, 2001 ("ABL Maturity
Date").

an ABL Loan, a representative of Bank shall have conducted an audit of
Borrower's books and records relating to the Accounts and Inventory and any
other Collateral for the ABL Loans and made extracts therefrom, and arranged
for verification of the Accounts, directly with the account debtors or
otherwise, and of the Inventory all with results satisfactory to Bank, the
cost of such audit shall be at Borrower's sole expense. Based on Bank's
review of such audit, and prior to the advance of an ABL Loan in accordance
with the terms hereof, Bank may adjust the Borrowing Base percentage, in its
sole and reasonable discretion, as provided for under Section 4.15 hereof..
Unless an Event of Default has occurred and continues, Bank shall conduct no
more than two (2) audits per calendar year.

(c)          LOAN LEDGER ACCOUNT; USE OF PROCEEDS. The amount of each ABL
Loan made by Bank to Borrower hereunder shall be debited to the loan ledger

the date of the advance of the initial ABL Loan through the ABL Maturity
Date, on or before the tenth (10th) day of each month, interest on the unpaid
balance of the ABL Loan Account at a rate of interest elected by the
Borrower, either at the Prime Rate, which shall vary concurrently with any
change in such Prime Rate, plus the Applicable ABL Prime Rate Margin or at
the LIBOR Rate plus the applicable ABL LIBOR Rate Margin.

6.08     CESSATION OF BUSINESS. Borrower shall voluntarily suspend its
business.

6.09     ADVERSE CHANGE. Any change which, in the reasonable opinion of Bank,
is materially adverse to the financial condition of Borrower or any
Guarantor; or should Bank, for any material reason, believe that the prospect
of Borrower's payment or performance hereunder or under any other agreement
or instrument with Bank be impaired.

6.10     OTHER DEFAULTS. Any default in the payment in excess of $25,000 or
performance of any obligation, or any defined event of default, under the
terms of any contract or instrument (other than any of the Loan Documents)
pursuant to which Borrower has incurred any debt or other liability to any
person or entity, including Bank, unless Borrower is contesting such default
in good faith to the Bank's satisfaction.

6.11     ADVANCES. Notwithstanding anything to the contrary contained herein,
Bank shall have no duty to make advances while any event of default exists
notwithstanding any cure period provided for herein.

6.12     RIGHT TO CURE. If any default, other than a default on indebtedness,
is curable, and if Borrower has not been given a prior notice of a breach of
the same provision of this agreement, it may be cured, (and no Event of
Default will have occurred), if Borrower, after Bank sends written notice
demanding cure of such default, (a) cures the default within ten (10) days,
or (b) if the cure requires more than ten (10) days, immediately initiates
steps which Bank deems, in Bank's sole discretion, to be sufficient to cure
the default and thereafter continues and completes all reasonable and
necessary steps sufficient to produce compliance as soon as reasonably
practical.

or monies of Borrower then or thereafter with Bank or other holder, within
ten (10) days after the Event of Default, and notice of the occurrence of any
Event of Default by Bank to Borrower.

(a) Other than (i) nonjudicial foreclosure and all matters in connection

the appointment of a receiver, or the exercise of other provisional remedies
(any and all of which may be initiated pursuant to applicable law), each
controversy, dispute or claim between the parties arising out of or relating
to this Credit Agreement, any security

                                       19
<PAGE>

agreement executed by Borrower in favor of Bank or any note executed by
Borrower in favor of Bank or any other agreement or instrument issued in
favor of Bank by Borrower (collectively in this Section, the "Agreement")
which controversy, dispute or claim is not settled in writing within thirty
(30) days after the "CLAIM DATE" (defined as the date on which a party
subject to this Agreement gives written notice to all other parties that a
controversy, dispute or claim exists), will be settled by a reference
proceeding in California in accordance with the provisions of Section 638 ET
SEQ. of the California Code of Civil Procedure, or their successor section
("CCP"), which shall constitute the exclusive remedy for the settlement of
any controversy, dispute or claim concerning this Agreement, including
whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or
jurisdiction other than the Superior Court in the County where the Real
Property, if any, is located or Los Angeles County if none (the "COURT"). The
referee shall be a retired Judge of the Court selected by mutual agreement of
the parties, and if they cannot so agree within forty-five (45) days after
the Claim Date, the referee shall be promptly selected by the Presiding Judge
of the Court (or his representative). The referee shall be appointed to sit
as a temporary judge, with all of the powers for a temporary judge, as
authorized by law, and upon selection should take and subscribe to the oath
of office as provided for in Rule 244 of the California Rules of Court (or
any subsequently enacted Rule). Each party shall have one peremptory
challenge pursuant to CCP Section 170.6. The referee shall (a) be requested
to set the matter for hearing within sixty (60) days after the date of
selection of the referee and (b) try any and all issues of law or fact and
report a statement of decision upon them, if possible, within ninety (90)
days of the Claim Date. Any decision rendered by the referee will be final,
binding and conclusive and judgment shall be entered pursuant to CCP Section
644 in any court in the state of California having jurisdiction. Any party
may apply for a reference proceeding at any time after thirty (30) days
following notice to any other party of the nature of the controversy, dispute
or claim, by filing a petition for a hearing and/or trial. All discovery
permitted by this Agreement shall be completed no later than fifteen (15)
days before the first hearing date established by the referee. The referee
may extend such period in the event of a party's refusal to provide requested
discovery for any reason whatsoever, including, without limitation, legal
objections raised to such discovery or unavailability of a witness due to
absence or illness. No party shall be entitled to "priority" in conducting
discovery. Depositions may be taken by either party upon seven (7) days
written notice, and request for production or inspection of documents shall
be responded to within ten (10) days after service. All disputes relating to
discovery which cannot be resolved by the parties shall be submitted to the
referee whose decision shall be final and binding upon the parties. Pending
appointment of the referee as provided herein, the Superior Court is
empowered to issue temporary and/or provisional remedies, as appropriate.

(b) Except as expressly set forth in this Agreement, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of all hearings, the order of presentation of evidence,
and all other questions that arise with respect to the course of the
reference proceeding. All proceedings and hearings conducted before the
referee, except for trial, shall be conducted without a court reporter except
that when any party so requests, a court reporter will be used at any hearing
conducted before the referee. The party making such a request shall have the
obligation to arrange for and pay for the court reporter. The costs of the
court reporter at the trial shall be borne equally by the parties.

(c) The referee shall be required to determine all issues in accordance with
existing case law and the statutory laws of the state of California. The
rules of evidence applicable to proceedings at law in the state of California
will be applicable to the reference proceeding. The referee shall be
empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable

                                       20
<PAGE>

orders that will be binding upon the parties. The referee shall issue a
single judgment at the close of the reference proceeding which shall dispose
of all of the claims of the parties that are the subject of the reference.
The parties hereto expressly reserve the right to contest or appeal from the
final judgment or any appealable order or appealable judgment entered by the
referee. The parties hereto expressly reserve the right to findings of fact,
conclusions of laws, a written statement of decision, and the right to move
for a new trial or a different judgment, which new trial, if granted, is also
to be a reference proceeding under this provision.

(d) In the event that the enabling legislation which provides for appointment
of a referee is repealed (and no successor statute is enacted), any dispute
between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration.
The arbitration will be conducted by a retired judge of the Court, in
accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time. The limitations with respect
to discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

by and between OBAGI MEDICAL PRODUCTS, INC. ("Borrower") and Imperial Bank

referred to herein as "Prime Loans" and each such advance shall be a "Prime
Loan." Each Prime Loan shall bear interest at an annual rate equal to the sum
of   *   % plus the Bank's Prime Rate. "Prime Rate" shall mean the rate of

this Addendum which bear interest in relation to the Libor Rate shall be
referred to herein as "Libor Loans" and each such advance shall be a "Libor
Loan." Each Libor Loan shall bear interest at the Libor Rate, as defined
below. A Libor Loan shall be in the minimum amount of One Million Dollars

     2. INTEREST ON LIBOR LOANS.

     2.1 RATE OF INTEREST. Each Libor Loan shall bear interest on the unpaid
principal amount thereof from the Loan Date through the date paid (whether by

the Libor Rate for the Interest Period.

         (a)  "Loan Date" shall mean the date on which (i) a Libor Loan is

Date of the Loan. Borrower may also select a twelve (12) month Interest
Period if and when Bank notifies Borrower that such Interest Period is
available, as determined by Bank in its sole discretion. During a Libor
Interest Period, interest shall be payable on the last day of the Interest
Period, provided that for any Interest Period longer than 3 months, interest
shall be payable quarterly and on the last day of the Interest Period.

         (c)  "Libor Rate" shall mean, for the applicable Interest Period for
a Libor Loan, a rate per annum (rounded upwards, if necessary, to the nearest
1/16 of 1%) equal to (i) the Libor Base Rate for such Interest Period divided
by (ii) 1.00 minus the Reserve Requirement Rate (expressed as a decimal
fraction) for such Interest Period.

         (d)  "Libor Base Rate" shall mean with respect to any Interest
Period, the rate equal to the arithmetic mean (rounded upwards, if necessary,
to the nearest 1/16 of 1%) of:

for a period equal to such Interest Period which appears at 11:00 a.m.,
London time, on the Reuters Screen LIBOR Page on the Business Day that is two
(2) Business Days before the first day of such Interest Period, in each case
if at least four (4) such offered rates appear on such page, or

              (ii)  if clause (i) is inapplicable, (x) the offered rate per
annum for deposits in U.S. Dollars for a period equal to such Interest Period
which appears as of 11:00 a.m., London time on the Telerate Monitor on
Telerate Screen 3750 on the Business Day which is two (2) Business Days
before the first day of such Interest Period; or (y) if clause (x) above is
inapplicable, the arithmetic mean (rounded upwards, if necessary, to the
nearest 1/16 of 1%) of the interest rates per annum offered by at least three
(3) prime banks selected by Bank at approximately 11:00 a.m. London time, on
the Business Day which is two (2) Business Days before such date for deposits
in U.S. Dollars to prime banks in the London interbank market, in each case
for a period equal to such Interest Period in an amount equal to the amount
to which the Libor Rate applies.

aggregate of the rates, effective as of the Business Day which is two (2)
Business Days before the first day of the Interest Period, at which:

               (i)  reserves (including any marginal, supplemental or
     emergency reserves) are required to be maintained during such Interest
     Period under Regulation D against "Eurocurrency liabilities" (as such
     term is used in Regulation D) by member banks of the Federal Reserve
     System; and

              (ii)  any additional reserves are required to be maintained by
     Bank by reason of any Regulatory Change against (x) any category of
     liabilities which includes deposits by reference to which the Libor Rate
     is to be determined as provided in the definition of "Libor Base Rate;"
     or (y) any category of extensions of credit or other assets which
     include Libor Loans.

          (h)  "Regulatory Change" means, with respect to Bank, any change on
or after the date of the Note and this Addendum in any Governmental
Regulation, including the introduction of any new Governmental Regulation or
the rescission of any existing Governmental Regulation.

          (i)  "Governmental Regulation" means any (i) United States
Federal, state or foreign law or regulation (including without limitation
Regulation D); and (ii) the adoption or making of any interpretation,
application, directive or request applying to a class of lenders, including
Bank, of or under any United States Federal, state, or any foreign law or
regulation (whether or not having the force of law) by any court or by any
governmental, central banking, monetary or taxing authority charged with the
interpretation or administration of such law or regulation.

     2.2  DETERMINATION OF INTEREST RATES.  Subject to the terms and
conditions of the Note and this Addendum, Borrower, at its option, may
request an advance in the form of a Libor Loan, a continuation of a Libor
Loan, or a conversion of a Prime Loan into a Libor Loan, only upon delivery
to Bank of an irrevocable written notice received by Bank at least three (3)
Business Days prior to the requested Loan Date, specifying (i) the principal
amount of such Libor Loan, (ii) the requested Loan Date, and (iii) the
selected Interest Period. Upon receiving such notice, Bank shall determine
(which determination shall be in accordance with Section 2.1 and shall,
absent manifest error, be final, conclusive and binding upon all parties
hereto) the Libor Rate applicable to such Libor Loan two (2) Business Days
prior to the Loan Date, and shall promptly give notice thereof (in writing or
by telephone confirmed in writing) to Borrower. If Borrower shall fail to
notify Bank of its selected Interest Period for a Libor Loan (including the
continuation of an existing Libor Loan or the conversion of a Prime Loan into
a Libor Loan), the Borrower shall be deemed to have selected an Interest
Period of three (3) months.

     2.3  COMPUTATION OF INTEREST AND FEES. All computations of interest and
fees payable pursuant to the Note shall be calculated on the basis of a three
hundred sixty (360) day year for the actual number of days elapsed (less the
date of repayment).

     2.4  RECORDATION BY BANK. Bank is hereby authorized to record the Loan
Date, the applicable Interest Period, the principal amount, and the interest
rate of each Libor Loan made (or continued or converted) by Bank, and the
date and amount of each payment or prepayment of principal thereof, in Bank's
records. Any such recordation shall constitute PRIMA FACIE evidence of the
accuracy of the information recorded; PROVIDED that the failure to make any
such recordation shall not in any way affect the Borrower's obligations
hereunder.

     3.  CONVERSION TO PRIME LOANS.

     3.1  ELECTION BY BORROWER.  Subject to all the terms and conditions of
this Addendum, Borrower may elect from time to time to convert a Libor Loan
to a Prime Loan by giving Bank at least three (3) Business Days' prior
irrevocable notice of such election, and any such conversion of a Libor Loan
shall be made on the last day of the Interest Period with respect thereto.

     3.2  FAILURE OF NOTICE BY BORROWER.  If Borrower otherwise fails to give
notice specifying its requests with respect to any Libor Loans that are
scheduled to become due, such failure shall be deemed, in the absence of any
notice from Borrower to the contrary, to be notice of a requested advance in
the form of a Prime Loan in a principal amount equal to the amount of said
Libor Loan.

     4.  PREPAYMENTS.

     4.1  VOLUNTARY PREPAYMENT BY BORROWER.  Subject to the terms and
conditions of the Note and this Addendum, Borrower may, upon at least three
(3) Business Days' irrevocable notice to Bank as provided herein, at any time
and from time to time on any Business Day prepay any Prime Loan or Libor
Loan in whole or in part, without penalty or premium, other than customary
actual "Breakage Fees" and "Prepayment Costs" as defined below, resulting
from prepayment of any Libor Loan prior to the expiration of the Interest
Period relating thereto. The notice of prepayment shall specify the date and
amount of the prepayment, and the Loan to which the

                                    Page 2 of 4

<PAGE>

prepayment applies. Each partial prepayment of a Libor Loan shall be in an
amount not less than One Hundred Thousand Dollars ($100,000) or such greater
amount which is an integral multiple of One Hundred Thousand Dollars
($100,000); PROVIDED that unless a Libor Loan is prepaid in full, no
prepayment shall be made if, after giving effect to such prepayment, the
aggregate principal amount of Libor Loans having the same Interest Period
shall be less than One Million Dollars ($1,000,000). Notice of prepayment
having been delivered as aforesaid, the principal amount of the prepayment
specified in such notice shall become due and payable on the prepayment date
set forth in such notice. All payments of principal under this Section 4
shall be accompanied by accrued but unpaid interest on the amount being
prepaid through the date of such prepayment.

      4.2   BREAKAGE FEES.  If for any reason (including voluntary or
mandatory prepayment, voluntary or mandatory conversion of a Libor Loan into
a Prime Loan, or acceleration), Bank receives all or part of the principal
amount of a Libor Loan prior to the last day of the Interest Period for such
Loan, Borrower shall immediately notify Borrower's account officer at Bank
and, on demand by Bank, pay Bank the Breakage Fees, defined as the amount (if
any) by which (i) the additional interest which would have been payable on
the amount so received had it not been received until the last day of such
Interest Period exceeds (ii) the interest which would have been recoverable
by Bank (without regard to whether Bank actually so invests said funds) by
placing the amount so received on deposit in the certificate of deposit
markets or the offshore currency interbank markets or United States Treasury
investment products, as the case may be, for a period starting on the date on
which it was so received and ending on the last day of such Interest Period
at the interest rate determined by Bank in its reasonable discretion. Bank's
determination as to such amount shall be conclusive and final, absent manifest
error.

      4.3   PREPAYMENT COSTS.  Borrower shall pay to Bank, upon the demand
of Bank, such other amount or amounts as shall be sufficient (in the sole
good faith opinion of Bank) to compensate it for any loss, costs or expense
incurred by it as a result of any prepayment by Borrower (including voluntary
or mandatory prepayment, voluntary or mandatory conversion of a Libor Loan
into a Prime Loan, or prepayment due to acceleration) of all or part of the
principal amount of a Libor Loan prior to the last day of the Interest Period
for such Loan (including without limitation any failure by Borrower to
borrow a Libor Loan on the Loan Date for such borrowing specified in the
relevant notice of borrowing hereunder). Such costs shall include, without
limitation, any interest or fees payable by Bank to lenders of funds obtained
by it in order to make or maintain its loans based on the London interbank
eurodollar market. Bank's determination as to such costs shall be conclusive
and final, absent manifest error.

      5.    REMEDIES UPON EVENTS OF DEFAULT.

      5.1   CONVERSION TO PRIME LOANS.  If any Event of Default has occurred
and is continuing under the Note or this Addendum, then in addition to all
other remedies available to Bank under the Note, at the option of Bank and
without demand or notice, all Libor Loans then outstanding shall be
automatically converted to Prime Loans on the last day of each respective
Interest Period for each Libor Loan.

      5.2   INDEMNITY.  Borrower agrees to pay and indemnify Bank for, and to
hold Bank harmless from, any and all cost, loss or expense (including without
limitation any such cost, loss or expense arising from interest or fees
payable by Bank to lenders of funds obtained by it in order to maintain its
Libor Loans hereunder, or in its reemployment of funds obtained in connection
with the making or maintaining of Libor Loans) which Bank may sustain or incur
as a consequence of any default by Borrower in connection with or related to:
(a) payment of the principal amount of or interest on Libor Loans, (b) making
a borrowing or conversion of a Libor Loan after Borrower has given a notice
thereof in accordance with this Addendum, or (c) making a prepayment of a
Libor Loan after Borrower has given a notice thereof in accordance with this
Addendum, or any prepayment (whether optional or mandatory) of any Libor Loan
prior to the end of the applicable Interest Period for such Loan.

      6.    ADDITIONAL PROVISIONS REGARDING LIBOR LOANS.

      6.1   LIBOR RATE TAXES.  All payments of principal, interest, fees,
costs, expenses and all other amounts payable by Borrower pursuant to the
Note and this Addendum shall be made free and clear of and without reduction
by reason of all present and future income, stamp and other taxes or other
charges whatsoever imposed, assessed, levied or collected by any national
government or any political subdivision or taxing authority thereof or any
organization of which it is a member (excluding (i) any taxes imposed on or
measured by the overall net income or gross receipts of Bank by any such
entity, and (ii) any taxes which would have been imposed even if no
provisions for Libor Loans had appeared in this Addendum) (collectively,
"Libor Taxes").

            If any Libor Taxes are required to be withheld from any amounts
payable to Bank, Borrower shall pay such additional amounts as may be
necessary so as to yield to Bank a net amount equal to the total amount of the
payments provided for in this Addendum or under the Note which Bank would
have received if such amounts had not been subject to Libor Taxes.

            If any Libor Taxes are payable directly by Borrower, they shall
be paid by Borrower prior to the date on which penalties attach for failure to
timely pay such Libor Taxes. Within forty five (45) days after the date on
which payment of any such Libor Taxes is due pursuant to applicable law,
Borrower will furnish Bank the original receipt for the full payment of
such Libor Taxes or, if such is not available, evidence of such payment
satisfactory in form and substance to Bank. Borrower shall indemnify and hold
Bank harmless against, and will reimburse to Bank, upon demand, any
incremental taxes, interest or penalties that may become payable by Bank as a
result of any failure by Borrower to pay any Libor Taxes when due.

      6.2  INABILITY TO DETERMINE FAIR INTEREST RATE.  If at any time Bank,
in its sole and absolute discretion, determines that: (i) the amount of the
Libor Loans for periods equal to the corresponding  Interest Periods are not
available to Bank in the offshore currency interbank markets, (ii) the Libor
Rate does not accurately reflect the cost to Bank of lending the Libor Loan,
or (iii) by reason of any changes arising after the date of the Note
affecting the London interbank eurodollar market, adequate and fair means do
not exist for ascertaining the applicable interest rate on the basis provided
for in Sections 2.1 and 2.2 above, then Bank shall promptly give notice
thereof to Borrower. Upon the giving of such notice, Bank's obligation to
make Libor Loans shall terminate, unless Bank and the Borrower agree in
writing to a different interest rate applicable to Libor Loans, or until such
time as Bank notifies Borrower that the circumstances giving rise to Bank's
notice no longer exist. While such circumstances continue to exist, (x)
any requested Libor Loan shall be treated as a request for a Prime Loan, (y)
any Prime Loan that was to have been converted to a Libor Loan shall be
continued as a Prime Loan, and (z) any outstanding Libor Loan shall be
converted retroactively, on the first day of the then current Interest Period
with respect thereto, to a Prime Loan.

      6.3   ILLEGALITY OR IMPRACTICABILITY.  If (i) due to any Governmental
Regulation it shall become unlawful for Bank to continue to fund or maintain
any Libor Loans, or to perform its obligations hereunder, or (ii) due to any
contingency occurring after the date of the Note which has a material adverse
effect on the London interbank eurodollar market, it has become
impracticable for Bank to continue to fund or maintain any Libor Loans, or to
perform its obligations hereunder, then Bank shall promptly give notice
thereof to Borrower. Upon the giving of such notice, Bank's obligation to
make Libor Loans shall terminate, and in such event, (x) any requested Libor
Loan shall be treated as a request for a Prime Loan, (y) any Prime Loan that
was to have been converted to a Libor Loan shall be continued as a Prime
Loan, and (z) any outstanding Libor Loan shall be converted retroactively,
on the first day of the then current Interest Period with respect thereto, to
a Prime Loan.

      6.4   GOVERNMENTAL REGULATIONS; INCREASED COSTS.  Borrower shall pay to
Bank within 15 days after demand by Bank, from time to time such amounts as
Bank may determine to be necessary to compensate it for any increased costs
incurred by Bank that Bank determines are attributable to its making or
maintaining of any Libor Loans to Borrower (such increases in costs and
reductions in amounts receivable being herein called "Additional Costs"),
in each case resulting from any Regulatory Change which:

            (a)   imposes a new tax or changes the basis of taxation of any
amounts payable to Bank under the Note of this Addendum in respect of any
Libor Loans (other than changes which affect taxes measured by or imposed on
the overall net income of Bank by the jurisdiction in which such Bank has its
principal office); or

            (b)   imposes or modifies any reserve, special deposit or similar
requirements relating to any extensions of credit or other assets of, or any
deposits or other liabilities with or for the account of Bank (including any
Libor Loans or any deposits referred to in the definition of  Libor Base
Rate); or

            (c)   imposes any other condition affecting the Note (or any of
such extensions of credit or liabilities); or

            (d)   imposes or modifies a Governmental Regulation regarding
capital adequacy which has or would have the effect of reducing the rate of
return on capital of Bank or any person or entity controlling Bank ("Parent")
as a consequence of its obligations hereunder to a level below that which
Bank (or its Parent) could have achieved but for such adoption, change or
compliance (taking into consideration its policies with respect to capital
adequacy) by an amount deemed by Bank to be material.

         Bank will notify Borrower of any event occurring after the date of
the Note which will entitle Bank to Additional Costs pursuant to this Section
6.4 as promptly as practicable after it obtains knowledge thereof and
determines to request such compensation. Bank will furnish Borrower with a
statement setting forth the basis and amount of each request by Bank for
Additional Costs under this Section 6.4. Determinations and allocations by
Bank for purposes of this Section 6.4 of the effect of any Regulatory Change
on its costs of maintaining its obligations to make Libor Loans or of making
or maintaining Libor Loans or on amounts receivable by it in respect of
Libor Loans, and of the additional amounts required to compensate Bank in
respect of any Additional Costs, shall be conclusive and final, absent
manifest error.

         This Addendum is executed as of the date first written above.

taxes, documentary taxes, assessments, or charges made by any governmental
authority of the United States of America, or any political subdivision or
governmental authority thereof or therein, and imposed on Bank by reason of the
execution and delivery of this Agreement, or any other document, instrument or
agreement entered into in connection herewith, excluding any taxes imposed on
Bank under the Internal Revenue Code or similar state and local laws and
determined by Bank's net income or revenue earned.

                           (c) Company shall and hereby agrees to indemnify,
protect, defend and hold harmless Bank and its directors, officers, agents,
employees and attorneys from and against any and all losses, claims, damages,
liabilities, deficiencies, judgments, costs and expenses (including attorneys'
fees and attorneys' fees incurred pursuant to proceedings arising under the
United States Bankruptcy Code) incurred by any of them (except to the extent
that it is finally judicially determined to have resulted from their own gross
negligence or willful misconduct) arising out of or by reason of any
litigations, investigations, claims or proceedings (whether administrative,
judicial or otherwise), including discovery, whether or not Bank is designated a
party thereto, which arise out of or are in any way related to (i) this
Agreement or the transactions contemplated hereby or thereby, or (ii) Bank's
entering into this Agreement or any other agreements and documents relating
hereto. If and to the extent that the obligations of Company hereunder are
unenforceable for any reason, Company hereby agrees to make the maximum
contribution to the payment and satisfaction of such obligations of Bank which
is permissible under applicable law.

                           (d) Company's obligations under this Section 6.3
shall survive any termination of this Agreement and the payment in full of the
Shared Appreciation Amount, and are in addition to, and not in substitution of,
any other of its obligations set forth in this Agreement.

                  6.4 AMENDMENTS AND WAIVERS. Any provision of this Agreement
may be amended or waived if, but only if, such amendment or waiver is in
writing and is signed by the party asserted to be bound thereby, and then
such amendment or waiver shall be effective only in the specific instance and
specific purpose for which given.

                  6.5 SUCCESSORS AND ASSIGNS; PARTICIPATIONS; DISCLOSURE.

                           (a) This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns,
except that Company may not assign or transfer any of its rights or obligations
under this Agreement without the prior written consent of Bank and any such
prohibited assignment or transfer by Company shall be void.

                           (b) Bank may, at its own expense, assign to one or
more banks or other financial institutions all or a portion of its rights under
this Agreement.

                           (c) Bank may at any time sell to one or more banks or
other financial institutions (each a "PARTICIPANT") participating interests in
any interest of Bank hereunder. In the event of any such sale by Bank of a
participating interest to a Participant, Company shall

                                      8
<PAGE>

continue to deal solely and directly with Bank in connection with Bank's
rights under this Agreement.

                           (d) Company authorizes Bank to disclose to any
assignee or any Participant (either, a "TRANSFEREE") and any prospective
Transferee any and all financial information in Bank's possession concerning
Company which has been delivered to Bank by Company pursuant to this Agreement
or which has been delivered to Bank by Company in connection with Bank's credit
evaluation prior to entering into this Agreement, subject to the Transferee's
written assumption of the same level of confidentiality as provided by Bank to
Company.

                  6.6 COUNTERPARTS; INTEGRATION. This Agreement may be signed in
any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement constitutes the entire agreement and understanding among the
parties hereto and supersedes any and all prior agreements and understandings,
oral or written, relating to the subject matter hereof.

                  6.7 SEVERABILITY. The provisions of this Agreement are
severable. The invalidity, in whole or in part, of any provision of this
Agreement shall not affect the validity or enforceability of any other of its
provisions. If one or more provisions hereof shall be declared invalid or
unenforceable, the remaining provisions shall remain in full force and effect
and shall be construed in the broadest possible manner to effectuate the
purposes hereof.

                  6.8 GOVERNING LAW. This Agreement shall be deemed to have been
made in the State of California and the validity, construction, interpretation,
and enforcement hereof, and the rights of the parties hereto, shall be
determined under, governed by, and construed in accordance with the internal
laws of the State of California, without regard to principles of conflicts of
law.

                  6.9 JUDICIAL REFERENCE.

                           (a) Other than (i) nonjudicial foreclosure and all
matters in connection therewith regarding security interests in real or personal
property; or (ii) the appointment of a receiver, or the exercise of other
provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to this Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in California in accordance with the provisions of Section
638 ET SEQ. of the California Code of Civil Procedure, or their successor
section ("CCP"), which shall constitute the exclusive remedy for the settlement
of any controversy, dispute or claim concerning this Agreement, including
whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than the Superior Court in the County where any real property collateral
is located, or Los Angeles County, if none (the "COURT"). The referee shall be a
retired Judge of the Court selected by mutual agreement of the parties, and if
they cannot so agree within forty-five (45) days after the Claim Date, the
referee shall be promptly selected by the Presiding Judge of the Court (or his
or

                                      9
<PAGE>

her representative). The referee shall be appointed to sit as a temporary
judge, with all of the powers for a temporary judge, as authorized by law,
and upon selection should take and subscribe to the oath of office as
provided for in Rule 244 of the California Rules of Court (or any
subsequently enacted Rule). Each party shall have one peremptory challenge
pursuant to CCP Section 170.6. The referee shall (i) be requested to set the
matter for hearing within sixty (60) days after the Claim Date and (ii) try
any and all issues of law or fact and report a statement of decision upon
them, if possible, within ninety (90) days of the Claim Date. Any decision
rendered by the referee will be final, binding and conclusive and judgment
shall be entered pursuant to CCP Section 644 in any court in the State of
California having jurisdiction. Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a
petition for a hearing and/or trial. All discovery permitted by this
Agreement shall be completed no later than fifteen (15) days before the first
hearing date established by the referee. The referee may extend such period
in the event of a party's refusal to provide requested discovery for any
reason whatsoever, including, without limitation, legal objections raised to
such discovery or unavailability of a witness due to absence or illness. No
party shall be entitled to "priority" in conducting discovery. Depositions
may be taken by either party upon seven (7) days written notice, and request
for production or inspection of documents shall be responded to within ten
(10) days after service. All disputes relating to discovery which cannot be
resolved by the parties shall be submitted to the referee whose decision
shall be final and binding upon the parties. Pending appointment of the
referee as provided herein, the Superior Court is empowered to issue
temporary and/or provisional remedies, as appropriate.

                           (b) Except as expressly set forth in this Agreement,
the referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding. All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee. The party making such a request
shall have the obligation to arrange for and pay for the court reporter. The
costs of the court reporter at the trial shall be borne equally by the parties.

                           (c) The referee shall be required to determine all
issues in accordance with existing case law and the statutory laws of the State
of California. The rules of evidence applicable to proceedings at law in the
State of California will be applicable to the reference proceeding. The referee
shall be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties. The referee shall issue a single judgment at the close
of the reference proceeding which shall dispose of all of the claims of the
parties that are the subject of the reference. The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee. The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

                           (d) In the event that the enabling legislation which
provides for appointment of a referee is repealed (and no successor statute is
enacted), any dispute between

                                      10
<PAGE>

the parties that would otherwise be determined by the reference procedure
herein described will be resolved and determined by arbitration. The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, `1280 through `1294.2 of the CCP as
amended from time to time. The limitations with respect to discovery as set
forth hereinabove shall apply to any such arbitration proceeding.

                                      11

                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed by their respective authorized officers as of the
day and year first above written.
