                    NATIONAL INSURANCE GROUP AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  Financial Information

         In the opinion of management, the financial information reflects all
      adjustments (consisting only of normal recurring adjustments) which are
      necessary to a fair presentation of financial position and results of
      operations for the interim periods. The results for the nine month period
      ended September 30, 1997 and September 30, 1996 are not necessarily
      indicative of the results to be expected in the future.

2.  Acquisition

         On September 18, 1997, two wholly owned subsidiaries of National
      Insurance Group, a California corporation (the "Company" or "National"),
      Pinnacle American Realty Tax Services, Inc., a Delaware corporation
      ("PARTS-VA"), and Pinnacle American Realty Tax Services of New York, Inc.,
      a Delaware corporation ("PARTS-NY") (PARTS-NY and PARTS-VA, collectively
      "PARTS"), acquired substantially all the assets and assumed certain
      liabilities of American Realty Tax Services, Inc., a Virginia corporation
      ("ARTS-VA"), and American Realty Tax Services of New York, Inc., a
      Virginia corporation ("ARTS-NY") (ARTS-NY and ARTS-VA, collectively
      "ARTS"). The acquisition agreement, dated August 15, 1997, as amended (the
      "Agreement"), was entered into by and among ARTS, the shareholders of
      ARTS, the Company, and New Arts Acquisition, Inc., a Delaware corporation,
      which is a wholly owned subsidiary of the Company ("New Arts"). On October
      1, 1997, PARTS-VA changed its name to Pinnacle Real Estate Tax Services,
      Inc. ("PRETS-VA"), and PARTS-NY changed its name to Pinnacle Real Estate
      Tax Services of New York, Inc. ("PRETS-NY") (PRETS-NY and PRETS-VA,
      collectively "PRETS").

         As consideration for the acquisition of certain assets of ARTS (the
      "ARTS Acquisition"), New Arts paid $9.2 million in cash and agreed to
      assume certain liabilities of ARTS. Pursuant to the Agreement, if the cash
      revenue of certain contracts of PRETS exceeds certain targets for the
      twelve months ended and including April 30, 1998, PRETS is required to pay
      additional consideration of up to $4 million according to a formula as set
      forth in the Agreement ("Additional Consideration"). Fifty percent of the
      Additional Consideration may be paid in the form of a three year note
      bearing interest at eight percent per annum. The remaining fifty percent
      of the Additional Consideration may be paid in cash. The Company has
      agreed to guarantee the payment of these obligations.

         The ARTS Acquisition was accounted for as a purchase of assets. The
      fair market value of the assets acquired from ARTS was approximately $4.4
      million. The fair market value of liabilities assumed was approximately
      $7.3 million, including approximately $7 million of deferred revenue
      related to PRETS' existing portfolio of loans. The amount of goodwill
      recorded in connection with the transaction was $12.7 million, which will
      be amortized over a 25-year period as a result of PRETS' long standing
      vendor and customer relationships. Since the ARTS Acquisition was executed
      only thirteen days prior to the end of the third quarter of 1997, the
      Company's results of operations for the third quarter and nine months
      ended September 30, 1997, were not materially affected by the ARTS
      Acquisition. The Company filed with the Securities and Exchange Commission
      a Form 8-K, Current Report, dated September 18, 1997, in connection with
      the ARTS Acquisition. The Company will file an amendment to the Form 8-K
      in which historical and pro-forma financial information for PRETS will be
      presented.

         The majority of tax service revenues earned by PRETS are from "life of
      loan" servicing contracts, which require customers to pay an up-front,
      one-time fee to receive real estate property tax tracking services over
      the life of a loan. The revenue from "life of loan" contracts is
      recognized over the estimated life of the loans in proportion to the
      amount of expenses incurred to 



                                       5
<PAGE>   8

      service the real estate property tax tracking on the subject loans. Since
      the bulk of expenses incurred in providing real estate property tax
      tracking on the loans occurs in the first year, a majority of the "life of
      loan" revenue is recognized within the first year of servicing. The
      remainder of the revenue is amortized in accordance with the estimated
      rate at which loans are paid off or otherwise are removed from the
      servicing portfolio. As a result of this revenue recognition policy, PRETS
      records a deferred revenue reserve on its balance sheet. As of
      September 30, 1997, deferred "life of loan" tax servicing revenue was $7.0
      million.

         The primary business of PRETS is real estate property tax information
      services for mortgage lending and mortgage loan servicing institutions.
      PRETS facilitates the payment by mortgage lenders and mortgage loan
      servicing companies of borrowers' escrowed and non-escrowed funds to
      local, county and state taxing authorities nationwide. PRETS obtains
      property tax data from various taxing authorities and integrates this
      information with loan data from its customer base. PRETS accomplishes this
      through a proprietary online database and software, as well as a network
      of customer service centers.

3. Financing

         In connection with the ARTS Acquisition, the Company and New Arts
      entered into a term note facility (the "Term Facility") with the Company's
      primary commercial bank. The Term Facility allows for a maximum borrowing
      of $11.3 million, including $2 million for any Additional Consideration
      which may be payable pursuant to the Agreement on or before May 25, 1998.
      The Term Facility matures in May, 2003, and calls for interest payments at
      the rate of prime plus one and one-quarter percent, beginning September,
      1997. Principal is paid monthly, beginning May 30, 1998, in accordance
      with a variable amortization schedule. Collateral for the loan includes
      non-insurance company cash deposits of the Company, the common stock of
      the Company's wholly owned subsidiary, Pinnacle Data Corporation, a
      California corporation, as well as the stock of PRETS and of New Arts. As
      of September 30, 1997, the Company had utilized $9.3 million of the $11.3
      million Term Facility.

         On September 18, 1997, the Company amended its $5 million revolving
      facility (the "Revolving Facility"). The primary amendment to the
      Revolving Facility was the reduction in borrowing limits to $1 million
      from $5 million. As of September 30, 1997, the Company had no borrowings
      under the Revolving Facility and was in compliance with the financial
      covenants of the Revolving Facility.

4.  Reclassification

         For comparative purposes, certain prior year amounts have been
      reclassified to conform to the current year presentation. Such
      reclassifications had no impact on the Company's net income or
      shareholders' equity.

5.  Earnings per share

         In February, 1997, the Financial Accounting Standards Board ("FASB")
      issued Statement of Financial Accounting Standards ("SFAS") No. 128. SFAS
      No. 128 is designed to improve the earnings per share ("EPS") information
      provided in the financial statements by simplifying the existing
      computational guidelines, revising the disclosure requirements, and
      increasing the comparability of EPS data on an international basis. SFAS
      No. 128 is required to be adopted on December 31, 1997. The Company does
      not believe that SFAS No. 128 will have a material impact on its financial
      statements.


6.  Comprehensive income

         In June, 1997, the FASB issued SFAS No. 130, Reporting Comprehensive
      Income. SFAS No. 130 establishes standards for the reporting and display
      of comprehensive income and its 



                                       6
<PAGE>   9

      components in a full set of general purpose financial statements.
      Comprehensive income is defined as the change in equity of a business
      enterprise during a period from transactions and other events and
      circumstances from non-owner sources. SFAS No. 130 is effective for fiscal
      years beginning after December 15, 1997. The Company does not believe that
      SFAS No. 130 will have a material impact on its financial statements.

7.  Segment reporting

         In June, 1997, the FASB issued SFAS No. 131, Disclosures about Segments
      of an Enterprise and Related Information. SFAS No. 131 requires
      publicly-held companies to report financial and other information about
      key revenue-producing segments of the entity for which such information is
      available and utilized by the chief operating decision maker. Specific
      information to be reported for individual segments includes profit or
      loss, certain revenue and expense items and total assets. A reconciliation
      of segment financial information to amounts reported in the financial
      statements would be provided. SFAS No. 131 is effective for fiscal years
      beginning after December 15, 1997. The Company does not believe that SFAS
      No. 131 will have a material impact on its financial statements.

8.  Subsequent events

         On November 1, 1997, the Company's Board of Directors declared a
      dividend of $0.11 per share. The dividend is payable on November 24, 1997,
      to shareholders of record on November 17, 1997.

           These quarterly interim financial statements are unaudited.

ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

    The following discussion should be read in conjunction with the interim
financial statements and the notes thereto, which are set forth elsewhere in
this report.

RESULTS OF OPERATIONS

General

    On September 18, 1997, two wholly owned subsidiaries of the Company acquired
substantially all the assets of ARTS and assumed certain liabilities. The
acquisitions were accounted for as purchases of assets and are described in
detail in the notes to the financial statements contained in this report. The
Company's results of operations for the third quarter ended and for the nine
months ended September 30, 1997, were not materially affected by this
transaction, since the transaction closed thirteen days before the end of the
quarter.

THIRD QUARTER OF 1997 COMPARED WITH THIRD QUARTER OF 1996:

Revenue

         Total revenue of the Company for the third quarter increased from $10.1
      million in 1996 to $13.2 million in 1997, an increase of $3.1 million, or
      31%. Revenues for the comparable period of 1996 included a change in a
      deferred revenue estimate, which increased reported revenue for that
      period by $885,000. Had this adjustment not been made, the Company would
      have recognized $9.2 million in the third quarter of 1996, instead of the
      reported $10.1 million.



                                       7
<PAGE>   10

   Net premiums written by the Company's wholly owned subsidiary, Great Pacific
Insurance Company, a California corporation (the "Insurance Subsidiary"), for
the third quarter increased from $2.7 million in 1996 to $5.1 million in 1997,
an increase of $2.4 million, or 90%. The increase in net premiums written was
primarily due to an increase in the volume of business from the Company's
existing mortgage hazard insurance tracking customers.

    Net premiums earned by the Insurance Subsidiary for the third quarter
increased from $3.0 million in 1996 to $4.7 million in 1997, an increase of $1.7
million, or 55%. Premium revenue is generally earned ratably over a twelve month
period from the inception date of each insurance policy written, and is affected
by policies written over the prior twelve months and by policies canceled during
the quarter. Such cancellations would be applicable to premiums written in all
prior periods. The combined effect of changes in premiums written, earned and
canceled within any period is measured in terms of the change in unearned
premiums. For the quarter ended September 30, 1997, unearned premiums increased
by $425,000, compared to a decrease in unearned premiums of $344,000 for the
same quarter of 1996. See also, "Item 2, Management's Discussion and Analysis of
Financial Condition and Results of Operations, Results of Operations, Nine
Months Ended September 30, 1997, Compared with the Nine Months Ended September
30, 1996, Revenue."

    Real estate information services revenues for the third quarter increased
from $4.9 million in 1996 to $5.9 million in 1997, an increase of $1 million, or
20%. This increase is primarily a result of higher volume of inquires from
existing flood zone determination customers. The real estate information
services revenues for the third quarter of 1996 included a change in a deferred
revenue estimate, which increased reported revenues by $885,000. Had this
adjustment not been made, real estate information services revenues would have
been $4 million, instead of the reported $4.9 million.

    Tracking fees for the third quarter increased from $1.4 million in 1996 to
$1.9 million in 1997, an increase of $500,000, or 39%. The increase was due
primarily to the addition of new customers.

Expenses

   Loss and loss adjustment expenses ("LAE") incurred for the third quarter
increased from $975,000 (32% of net premiums earned) in 1996 to $1.6 million
(34% of net premiums earned) in 1997, an increase of $630,000, or 65%. The
average loss and LAE per new claim reported in the third quarter of 1997 was
approximately $6,080, compared to $5,600 for the same period in 1996. The number
of losses increased from 173 in 1996 to 264 in 1997.

    Commissions to non-affiliates in the third quarter decreased from $346,000
(11.3% of net premiums earned) in 1996 to $152,000 (3.2% of net premiums earned)
in 1997, a decrease of $194,000, or 56%. The decrease in the amount of
commission expense is due to a decline in net premiums written by independent
agents. The percentage of commissions paid to net premiums earned varies
depending upon customer mix. The decrease as a percentage of net premiums is due
primarily to the fact that a larger percentage of the Insurance Subsidiary's
business is produced by lenders who earn lower commission rates.

   Personnel expenses in the third quarter increased from $4.3 million in 1996
to $5.7 million in 1997, an increase of $1.4 million, or 33%. This increase was
a result of an increase in hiring in response to volume increases in net
premiums written, flood zone determinations, and motor vehicle tracking 



                                       8
<PAGE>   11

business. Personnel expenses as a percent of total revenue remained constant
at 43% from 1996 to 1997.

    All other expenses in the third quarter increased from $3.1 million in 1996
to $4.4 million in 1997, an increase of $1.3 million, or 41%. The increase was
primarily due to additional costs incurred to handle the increase in the volume
of business in each of the Company's subsidiaries.

    As a result of the above factors, income before provision for income taxes
for the third quarter decreased from $1.37 million in 1996 to $1.36 million in
1997, a decrease of approximately $10,000. Net Income for the third quarter of
1996 was $870,000, or $0.22 per share compared with net income of $878,000, or
$0.22 per share in 1997. The weighted average number of shares outstanding for
the third quarter of 1996 and 1997 were 3,996,897 and 4,063,047, respectively.

NINE MONTHS ENDED SEPTEMBER 30, 1997, COMPARED WITH THE NINE MONTHS ENDED
SEPTEMBER 30, 1996:

Revenue

   Total revenue of the Company for the nine month period increased from $30.7
million in 1996 to $36.7 million in 1997, an increase of $6.0 million, or 20%.
Revenues for the comparable period of 1996 included a change in a deferred
revenue estimate, which increased reported revenue for that period by $885,000.
Had this adjustment not been made, the Company would have recognized revenues of
$29.8 million in the third quarter of 1996, instead of the reported $30.7
million.

    Net premiums written for the period increased from $8.7 million in 1996 to
$14.9 million in 1997, an increase of $6.2 million, or 71%. The increase in net
premiums written was primarily due to an increase in the volume of business from
the Company's existing mortgage tracking customers.

    Net premiums earned by the Insurance Subsidiary for the period increased
from $9.9 million in 1996 to $13.4 million in 1997, an increase of $3.5 million,
or 35%. Premium revenue is generally earned ratably over a twelve month period
from the inception date of each insurance policy written, and is affected by
policies written over the prior twelve months and by policies canceled during
the applicable accounting period. Such cancellations would be applicable to
premiums written in all prior periods. The combined effect of changes in
premiums written, earned and canceled within any period is measured in terms of
the change in unearned premiums. For the nine months ended September 30, 1997,
unearned premiums increased by $1.5 million, compared to a decrease in unearned
premiums of $1.2 million for the same nine months of 1996.

     The Company has received notice from a customer that it would not renew its
hazard insurance tracking and force-place insurance contract effective October
31, 1997. Such customer accounted for 1.6% of consolidated revenue in 1995, 3.3%
in 1996 and 11% in the first nine months of 1997. Management believes that the
decrease in revenue due to the loss of this customer may be material, but will
be offset, in part, by changes in certain reserves potentially arising from the
customer's departure, and additional business from new and existing customers;
and, delayed by the rate at which the unearned premium for such customer is
earned over the next twelve months. The Company is presently unable to estimate
the amount of such offsets, which are dependent upon numerous factors,
including, without limitation, the general health of the mortgage banking and
vehicle financing industries, interest rates, general economic conditions, the
realization of expected new business from new and existing customers 



                                       9

and other factors. These factors, together with statements regarding certain
risks and uncertainties contained in other parts of this report, may affect the
Company's operating results. Investors should read this paragraph, which
contains forward looking statements, in connection with any other
forward looking statement made in this report, including, but not limited to,
statements preceded or followed by the words "believes", "anticipates",
"expects", "aware" or similar expressions as they relate to the Company or its
management.

    Real estate information services revenues for the period increased from
$14.5 million in 1996 to $15.9 million in 1997, an increase of $1.4 million, or
10%. This increase is primarily a result of higher volume of inquiries from
existing flood zone determination customers. The real estate information
services revenues for the nine months ended September 30, 1996, included a
change in a deferred revenue estimate, which increased reported revenues by
$885,000. Had this adjustment not been made, real estate information services
revenues would have been $13.6 million, instead of the reported $14.5 million.

    Tracking fees for the period increased from $3.9 million in 1996 to $5.5
million in 1997, an increase of $1.6 million, or 42%. The increase was due
primarily to the addition of new customers.

Expenses

    Loss and LAE incurred for the nine month period increased from $3.6 million
(36.9% of net premiums earned) in 1996 to $4.5 million (34% of net premiums
earned) in 1997, an increase of $900,000, or 23%. The average loss and LAE per
new claim reported in the nine month period ended September 30, 1997, was
approximately $7,209, compared to $6,100 for the same period in 1996. The number
of losses increased from 595 in 1996 to 623 in 1997.

    Commissions to non-affiliates for the period decreased from $1.6 million
(16.2% of net premiums earned) in 1996 to $1.3 million (9.4% of net premiums
earned) in 1997, a decrease of $300,000, or 18.8%. The percentage of commissions
paid to net premiums earned varies depending upon customer mix. The decrease is
due primarily to the fact that a larger percentage of the Insurance Subsidiary's
business is being produced by lenders who earn lower commission rates.

    Personnel expenses for the period increased from $14.5 million in 1996 to
$16.3 million in 1997, an increase of $1.8 million, or 13%. This increase was in
response to volume increases in the volume of net written premiums, flood zone
determinations and motor vehicles tracked. Personnel expenses as a percent of
total revenue decreased from 47.2% in 1996 to 44% in 1997. The reduction was
primarily due to the fact that personnel expenses from the comparable period of
1996 included expenses of $1.37 million from executive retention agreements
entered into in the second quarter of 1996 in connection with a change in
management of the Company. Had these expenses not occurred, the Company would
have recognized $13.1 million in personnel expenses in the comparable period of
1996, instead of the reported $14.5 million; accordingly, personnel expenses as
a percentage of revenues would have been 43%, instead of 47.2%.

    All other expenses in the nine month period increased nominally from $10.7
million in 1996 to $10.8 million in 1997, an increase of $100,000, or 1%.

    As a result of the above factors, pre-tax income for the nine month period
increased from $255,000 in 1996 to $3.9 million in 1997, an increase of $3.6
million. The pre-tax income from last year's 



                                       10
<PAGE>   13

comparable period included a change in a deferred revenue estimate, as well as
costs incurred in connection with executive retention agreements. The deferred
revenue adjustment increased reported revenue and pre-tax earnings for the
period by $885,000; the expenses recognized in connection with the executive
retention agreements lowered reported pre-tax earnings for the period by $1.37
million. Had this adjustment and expense not occurred, the Company would have
recognized pre-tax income for the nine months ended September 30, 1996, of
$751,000, instead of the reported pre-tax income of $255,000; net income would
have been $477,000, or $0.12 per share, instead of the reported net income of
$162,000, or $0.04 per share. The weighted average number of shares outstanding
for the nine months ended September 30, 1996, and 1997 were 3,985,708 and
4,049,796, respectively.

LIQUIDITY AND CAPITAL RESOURCES

    National is a holding company with no operations and no sources of income
itself except interest or investment income. The principal assets of National
are the stock of its subsidiaries. National is, and for the foreseeable future
will continue to be, dependent on the dividends from its subsidiaries to meet
its liquidity requirements, including debt service obligations. Dividends
payable to National by the Insurance Subsidiary are subject to certain
regulatory restrictions described below.

    The Insurance Subsidiary collects and invests premiums written in advance of
the payments for associated claims. In the absence of a catastrophic loss, this
timing difference between premium collection and claims payment, combined with
investment income, normally provides short-term funds in excess of normal
operating demands for cash. As of September 30, 1997, the Company had cash and
short-term investments aggregating $15.7 million compared to $13.2 million at
December 31, 1996.

    Of the Company's cash and short-term investments as of September 30, 1997,
$8.3 million is held by the Insurance Subsidiary compared to $8.3 million at
December 31, 1996. Insurance companies, including the Insurance Subsidiary, are
subject to laws and regulations which restrict their ability to pay dividends to
parent companies or other shareholders. Under California law, the maximum amount
of dividends that the Insurance Subsidiary may pay the Company in any twelve
month period without prior regulatory approval is the greater of (i) net income
for the preceding calendar year, or (ii) 10% of policyholders' surplus
(shareholders' equity adjusted to a statutory basis) as of the previous December
31. For the year ended December 31, 1996, the Insurance Subsidiary had net
income of approximately $2.8 million and as of December 31, 1996, statutory
policyholders' surplus of $26.8 million. Accordingly, for the year ended
December 31, 1996, the maximum dividend permitted by the Insurance Subsidiary to
National was approximately $2.8 million. On April 10, 1997, the Insurance
Subsidiary made a dividend payment to National in the amount of $2.5 million.

    On September 18, 1997, the Company entered into a secured term note facility
(the "Term Facility") with a commercial bank. The Term Facility allows for a
maximum borrowing of $11.3 million, the proceeds of which may only be used for
purposes of acquiring the assets of ARTS. As of September 30, 1997, the
Company's borrowings under the Term Facility were $9.3 million. The remaining
portion of the Term Facility may be used for paying additional consideration for
ARTS in accordance with the Asset Purchase Agreement dated August 15, 1997, as
amended. As of September 30, 1997, the Company was in compliance with all
financial ratio and minimum net worth requirements per the terms of the Term
Facility.

    On September 18, 1997, the Company amended its $5 million revolving facility
(the "Revolving Facility"). The primary amendment to the Revolving Facility was
the reduction in borrowing limits to 



                                       11
<PAGE>   14

$1 million from $5 million. As of September 30, 1997, the Company had no
borrowings under the Revolving Facility and was in compliance with the financial
covenants of the Revolving Facility.

    In addition to the Term Facility and Revolving Facility, the Company has a
remaining balance of $500,000 due under a $2 million note payable (the "Term
Loan") as of September 30, 1997. As of September 30, 1997, the Company is in
compliance with the financial covenants of the Term Loan.

    Consolidated shareholders' equity at September 30, 1997, totaled $27.1
million, or $6.80 per share, compared to $28.6 million, or $7.33 per share, at
December 31, 1996.

    Industry and regulatory guidelines suggest that a property and casualty
insurers' annual statutory net written premium should not exceed approximately
three times its policyholder surplus. The Company's surplus ratio is
significantly lower than such guidelines. For the year ended December 31, 1996,
the Company's net written premium to policyholder surplus ratio was .50 to 1.
Management believes that as of September 30, 1997, that ratio has not materially
changed.

    The Company is not aware of any trends, requirements, commitments, or events
that will or are reasonably likely to have a material negative impact on the
Company's liquidity during 1997. This report contains forward-looking statements
reflecting the Company's current expectations. There can be no assurance that
the Company's actual future performance will meet the Company's current
expectations. 

    Inflation generally affects the rate of investment return in the securities
and financial markets, and increases and decreases in such investment return
rates have a corresponding effect on the Company's investment income.

          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 of 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 Claim Date 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 644.90 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 


                                       3
<PAGE>   10
          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 law, 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.

     5.   The Borrower hereby agrees that as long as New Arts remains obligated
          to the Bank the provisions of Sections B.4, B.5, B.6, and B.7 of the
          Agreement shall remain in full force and effect and shall survive
          repayment if full of all obligations of Borrower to Bank or the
          termination of the Agreement or if the Agreement is no longer in
          effect for any reason. Any breach of this provision shall result in a
          default in the New Arts Credit Agreement.

     6.   Except as provided above, the Agreement remains unchanged.

        your Bank or any holder of Notes issued hereunder, in the exercise of
        any power, right or privilege hereunder shall operate as a waiver
        thereof, nor shall any single or partial exercise of any such power,
        right or privilege preclude other or further exercise thereof or of any
        other right, power or privilege. All rights and remedies existing under

        notice and upon the effective termination date, the Borrower has no
        outstanding principal, interest, penalties, or any other amounts due
        under this agreement. Upon termination, Lender's interest in all
        Collateral of Borrower shall cease.

F.   Applicable Law and Reference Provisions

     1.   APPLICABLE LAW.  This Agreement and all other agreements and
          instruments required by Bank in connection therewith shall be governed
          by and construed according to the laws of the State of California, to
          the jurisdiction of which the parties hereby agree to submit.

     2.   REFERENCE PROVISIONS.

          (a). Other than (i) non-judicial 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 the 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 securing this Agreement, 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 of 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 Claim Date
               and (b) try any and all issues of law or fact and report a
               statement of decision upon them, if




                                       7

<PAGE>   8
               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 644.90 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 law, 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.

                              [IMPERIAL BANK LOGO]

                                      NOTE


$11,268,000.00              Walnut Creek, California         September 11, 1997

On March 30, 2003, and as hereinafter provided, for value received, the
undersigned promises to pay to IMPERIAL BANK ("Bank") a California banking
corporation, or order, at its East Bay Regional office, the principal sum of
$11,268,000.00 or such sums up to the maximum if so stated, as the Bank may now
or hereafter advance to or for the benefit of the undersigned in accordance with
the terms hereof, together with interest from date of disbursement or (N/A),
whichever is later, on the unpaid principal balance [ ] at the rate of ____% per
year [X] at the rate of 1.250% per year in excess of the rate of interest which
Bank has announced as its prime lending rate (the "Prime Rate"), which shall
vary concurrently with any change in such Prime Rate, or $250.00, whichever is
greater. Interest shall be computed at the above rate on the basis of the actual
number of days during which the principal balance is outstanding, divided by
360, which shall, for interest computation purposes, be considered one year.

Interest shall be payable [X] monthly [ ] quarterly [X] included with principal
[ ] in addition to principal [ ] beginning September 30, 1997, and if not so
paid shall become a part of the principal. All payments shall be applied first
to any late charges owing, then to interest and the remainder, if any, to
principal. [X] (if checked), Principal shall be payable in installments of
$______________, or more, each installment on the 30th day of each month,
beginning May 30, 1998. Advances not to exceed any unpaid balance owing at any
one time equal to the maximum amount specified above, may be made at the option
of Bank.

        Any partial prepayment shall be applied to the Installments, if any, in
inverse order of maturity. Should default be made in the payment of principal or
interest when due, or in the performance or observance, when due, of any item,
covenant or condition of any deed of trust, security agreement or other
agreement (including amendments or extensions thereof) securing or pertaining to
this note, at the option of the holder hereof and without notice or demand, the
entire balance of principal and accrued interest then remaining unpaid shall (a)
become immediately due and payable, and (b) thereafter bear interest, until paid
in full, at the increased rate of 5% per year in excess of the rate provided for
above, as it may vary from time to time.

        Defaults shall include*

        If any installment payment, interest payment, principal payment or
principal balance payment due hereunder is delinquent ten or more days, Obligor
agrees to pay Bank at late charge in the amount of 5% of the payment so due and
unpaid, in addition to the payment; but nothing in this paragraph is to be
construed as any obligation on the part of the holder of this note to accept
payment of any payment past due or less than the total unpaid principal balance
after maturity.

        If this note is not paid when due, each Obligor promises to pay all
costs and expenses of collection and reasonable attorneys fees incurred by the
holder hereof on account of such collection, plus interest at the rate
applicable to principal, whether or not suit is filed hereon. Each Obligor shall
be jointly and severally liable hereon and consents to renewals, replacements
and extensions of time for payment hereof, before, at, or after maturity;
consents to the acceptance, release or substitution of security for this note;
and waives demand and protest and the right to assert any statute of
limitations. Any married person who signs this note agrees that recourse may be
had against separate property for any obligations hereunder. The indebtedness
evidenced hereby shall be payable in lawful money of the United States. In any
action brought under or arising out of this note, each Obligor, including
successor(s) or assign(s) hereby consents to the application of California law,
to the jurisdiction of any competent court within the State of California, and
to service of process by any means authorized by California law.

        No single or partial exercise of any power hereunder, or under any deed
of trust, security agreement or other agreement in connection herewith shall
preclude other or further exercises thereof or the exercise of any other such
power. The holder hereof shall at all times have the right to proceed against
any portion of the security for this note in such order and in such manner as
such holder may consider appropriate, without waiving any rights with respect to
any of the security. Any delay or omission on the part of the holder hereof in
exercising any right hereunder, or under any deed of trust, security agreement
or other agreement, shall not operate as a waiver of such right, or of any other
right, under this note or any deed of trust, security agreement or other
agreement in connection herewith.

                                      NOTE

$ 1,000,000.00              Walnut Creek, California, September 11, 1997

On     March 31, 1998     , and as hereinafter provided, for value received,
the undersigned promises to pay to IMPERIAL BANK ("Bank") a California banking
corporation, or order, at its East Bay Regional office, the principal sum of
$1,000,000.00 Maximum or such sums up to the maximum if so stated, as the Bank
may now or hereafter advance to or for the benefit of the undersigned in
accordance with the terms hereof, together with interest from date of
disbursement or (N/A), whichever is later, on the unpaid principal balance
[  ] at the rate of       % per year [X] at the rate of 0.750% per year in
excess of the rate of interest which Bank has announced as its prime lending
rate (the "Prime Rate"), which shall vary concurrently with any change in such
Prime Rate, or $250.00, whichever is greater. Interest shall be computed at the
above rate on the basis of the actual number of days during which the principal
balance is outstanding, divided by 360, which shall, for interest computation
purposes, be considered one year.

Interest shall be payable [X] monthly [ ] quarterly [ ] included with principal
[ ] in addition to principal [ ] beginning September 30, 1997, and if not so
paid shall become a part of the principal. All payments shall be applied first
to any late charges owing, then to interest and the remainder, if any, to
principal. [ ] (If checked), Principal shall be payable in Installments of
$        or more, each installment on the       day of each               ,
beginning                              . Advances not to exceed any unpaid
balance owing at any one time equal to the maximum amount specified above, may
be made at the option of Bank.

     Any partial prepayment shall be applied to the installments, if any, in
inverse order of maturity. Should default be made in the payment of principal
or interest when due, or in the performance or observance, when due, of any
item, covenant or condition of any deed of trust, security agreement or other
agreement (including amendments or extensions thereof) securing or pertaining
to this note, at the option of the holder hereof and without notice or demand,
the entire balance of principal and accrued interest then remaining unpaid
shall (a) become immediately due and payable, and (b) thereafter bear interest,
until paid in full, at the increased rate of 5% per year in excess of the rate
provided for above, as it may vary from time to time.

     Defaults shall include*

     If any installment payment, interest payment, principal payment or
principal balance payment due hereunder is delinquent ten or more days, Obligor
agrees to pay Bank a late charge in the amount of 5% of the payment so due and
unpaid, in addition to the payment; but nothing in this paragraph is to be
construed as any obligation on the part of the holder of this note to accept
payment of any payment past due or less than the total unpaid principal balance
after maturity.

     If this note is not paid when due, each Obligor promises to pay all costs
and expenses of collection and reasonable attorneys fees incurred by the holder
hereof on account of such collection, plus interest at the rate applicable to
principal, whether or not suit is filed hereon. Each Obligor shall be jointly
and severally liable hereon and consents to renewals, replacements and
extensions of time for payment hereof, before, at, or after maturity,
consents to the acceptance, release or substitution of security for this note,
and waives demand and protest and the right to assert any statute of
limitations. Any married person who signs this note agrees that recourse may be
had against separate property for any obligations hereunder. The indebtedness
evidenced hereby shall be payable in lawful money of the United States. In any
action brought under or arising out of this note, each Obligor, including
successor(s) or assign(s) hereby consents to the application of California law,
to the jurisdiction of any competent court within the State of California, and
to service of process by any means authorized by California law.

     No single or partial exercise of any power hereunder, or under any deed of
trust, security agreement or other agreement in connection herewith shall
preclude other or further exercises thereof or the exercise of any other such
power. The holder hereof shall at all times have the right to proceed against
any portion of the security for this note in such order and in such manner as
such holder may consider appropriate, without waiving any rights with respect to
any of the security. Any delay or omission on the part of the holder hereof in
exercising any right hereunder, or under any deed of trust, security agreement
or other agreement, shall not operate as a waiver of such right, or of any other
right, under this note or any deed of trust, security agreement or other
agreement in connection herewith.

*those defaults in that Credit Terms and Conditions between the undersigned and
the Bank. 
Any default under the obligations of New Arts Acquisition, Inc. to
Bank shall constitute a default hereunder.

[LOGO IMPERIAL BANK LOGO]

CONTINUING GUARANTEE

                          ORIGINATING OFFICE:

                              NAME OF OFFICE: East Bay Regional Office

                              STREET ADDRESS: 1331 N. California Blvd., Ste. 320

                       CITY, STATE, ZIP CODE: Walnut Creek, CA  94596-9504


     The undersigned (hereinafter referred to as "Guarantor") hereby requests
and authorizes IMPERIAL BANK (hereinafter referred to as the "Bank") to extend
credit to New Arts Acquisition, Inc. a Corporation (Designate type of entity) 
(hereinafter referred to as "Debtor"), and in consideration of the granting of
such credit by the Bank to Debtor, Guarantor agrees as follows:

     1.  The words "indebtedness" and "credit" are used herein in their most
comprehensive sense and include any and all advances, debts, obligations and
liabilities, including interest thereon, of Debtor heretofore, now or hereafter
made, incurred or created, with or without notice to Guarantor, whether
voluntary or involuntary and however arising, whether due or not due, absolute
or contingent, liquidated or unliquidated, determined or undetermined, whether
assumed by Debtor's successors, heirs or assigns by operation of law or
otherwise, and whether Debtor is liable individually or jointly with others,
and whether recovery upon any such indebtedness or credit is or hereafter
becomes barred by any statute of limitations or is or hereafter becomes
otherwise unenforceable.

     2.  Credit may be granted from time to time at the request of Debtor and
without further authorization from or notice to Guarantor, even though Debtor's
financial condition may have deteriorated since the date hereof. If Debtor is a
corporation or a partnership,the Bank need not inquire into the power of
Debtor or the authority of its officers, directors, partners or agents acting
or purporting to act in its behalf. Each credit heretofore or hereafter granted
to Debtor shall be considered to have been granted at the special instance and
request of Guarantor and in consideration of and in reliance upon this
guarantee.

     3.  Guarantor hereby unconditionally guarantees and promises to pay the
Bank or its order any and all indebtedness of Debtor to the Bank and to perform
any and all obligations of Debtor under the terms of any agreement or
instrument evidencing, securing or executed in connection with any such
indebtedness ("Credit Documents"). The liability of guarantor shall not at any
time exceed the sum of the amount set forth below, plus the interest thereon in
accordance with the Credit Documents and the costs, attorneys' fees and other
expenses provided for in Paragraph 15 hereof. If no amount is set forth below,
the liability of the Guarantor hereunder shall be unlimited. The Bank may permit
Debtor's indebtedness to exceed any maximum liability without impairing the
obligations of Guarantor hereunder. No payments made by or on behalf of
Guarantor to the Bank shall reduce any such maximum liability unless written
notice to that effect is received by the Bank at or prior to the time such
payment is made. If Guarantor has executed more than one guarantee of the
indebtedness of Debtor to the Bank, the guarantees shall be cumulative.

     4.  Either before or after revocation hereof and in such manner, upon such
terms and at such times as it considers best and with or without notice to
Guarantor, the Bank may alter, compromise, accelerate, extend or change the time
or manner for the payment of any indebtedness hereby guaranteed, increase or
reduce the rate of interest thereon, release or add any one or more guarantors
or endorsers, accept additional or substituted security therefor, or release or
subordinate any security therefor. No exercise or nonexercise by the Bank of any
right hereby given it, no dealing by the Bank with Debtor or any other person,
and no change, impairment or suspension of any right or remedy of the Bank shall
in any way affect any of the obligations of Guarantor hereunder or any security
furnished by Guarantor or give Guarantor any recourse against the Bank.

     5.

                                  Page 1 of 4
<PAGE>   2
     6.  Guarantor waives and agrees not to assert or take advantage of (a) any
right to require the Bank to proceed against the Debtor or any other person,
firm or corporation or to proceed against or exhaust any security held by it at
any time or to pursue any other remedy in its power; (b) the defense of the
statute of limitations in any action hereunder or for the collection of any
indebtedness or the performance of any obligation guaranteed hereby; (c) any
defense that may arise by reason of the incapacity, lack of authority, death or
disability of, or revocation hereof by any other or others or the failure of
the Bank to file or enforce a claim against the estate (either in
administration, bankruptcy, or other proceeding) of any other or others; (d)
demand, protest and notice of any kind including, without limiting the
generality of the foregoing, notice of the existence, creation or incurring of
new or additional indebtedness or of any action or non-action on the part of
the Debtor, the Bank, any endorser, creditor of Debtor or Guarantor under this
or any other instrument, or any other person whomsoever, in connection with any
obligation or evidence of indebtedness hereby guaranteed; (e) any defense based
upon an election of remedies by the Bank, including without limitation, an
election to proceed by nonjudicial rather than judicial foreclosure, which
election destroys or otherwise impairs subrogation rights of Guarantor or the
right of Guarantor to proceed against Debtor for reimbursement, or both,
including, without limitation, the impairment of subrogation rights arising by
virtue of California Civil Code 580(b) and 580(d); (f) any defense or right
based upon the fair value deficiency protections and provisions of California
Civil Code 580(a) and California Civil Procedure Code 726; and (g) any defense
or right based upon the acceptance by the Bank or an affiliate of the Bank of a
deed in lieu of foreclosure, without extinguishing the indebtedness, even if
such acceptance destroys, alters or otherwise impairs subrogation rights of
Guarantor or the right of Guarantor to proceed against Debtor for
reimbursement, or both.

     7.  Guarantor, by execution hereof, represents to the Bank that the
relationship between Guarantor and Debtor is such that Guarantor has access to
all relevant facts and information concerning the indebtedness and Debtor and
that the Bank can rely upon Guarantor having such access. Guarantor waives and
agrees not to assert any duty on the part of the Bank to disclose to Guarantor
any facts that the Bank may now or hereafter know about Debtor, regardless of
whether the Bank has reason to believe that any such facts materially increase
the risk beyond that which Guarantor intends to assume, or has reason to believe
that such facts are unknown to Guarantor, or has a reasonable opportunity to
communicate such facts to Guarantor. Guarantor is fully responsible for being
and keeping informed of the financial condition of Debtor and all circumstances
bearing on the risk of non-payment of the indebtedness guaranteed hereby.

     8.  Until all indebtedness of Debtor to the Bank has been paid in full,
even though such indebtedness is in excess of the liability of Guarantor,
Guarantor shall have no right of subrogation and waives any right to enforce
any remedy which the Bank now has or may hereinafter have against Debtor and
any benefit of and any right to participate in any security now or hereinafter
held by the Bank.

     9.  Except as otherwise provided in this paragraph, upon a default
hereunder or in any obligation guaranteed hereunder all existing or future
indebtedness of Debtor to Guarantor and, if Debtor is a partnership, any right
to withdraw any capital of Guarantor invested in Debtor, is hereby subordinated
to all indebtedness hereby guaranteed and, without the prior written consent of
the Bank, shall not be paid or withdrawn in whole or in part nor will Guarantor
accept any payment of or on account of any such indebtedness or as a withdrawal
of capital while this guarantee is in effect. At the Bank's request, Debtor
shall pay to the Bank all or any part of subordinated indebtedness and any
capital which Guarantor is entitled to withdraw. Each payment by Debtor to
Guarantor in violation of this paragraph shall be received in trust for the Bank
and shall be paid to the Bank immediately on account of the indebtedness of
Debtor to the Bank. No such payment shall reduce or affect in any manner
Guarantor's liability under any of the provisions of this guarantee. Guarantor
reserves the right to receive from Debtor payment of any salary for personal
services at the same monthly rate as that at which Guarantor has been paid
during the preceding twelve months, it being expressly understood that such
amount shall not be subordinated to the indebtedness guaranteed hereby.

    10.  Guarantor will file all claims against Debtor in any bankruptcy or
other proceeding in which the filing of claims is required by law upon any
indebtedness of Debtor to Guarantor and shall concurrently assign to the Bank
all of the Guarantor's rights thereunder. If Guarantor does not file any such
claim, the Bank, as Guarantor's attorney-in-fact, is hereby authorized to do so
in Guarantor's name or, in the Bank's discretion, to assign the claim and to
cause proof of claim to be filed in the name of the Bank's nominee. In all such
cases, whether in administration, bankruptcy or otherwise, the person or
persons authorized to pay such claims shall pay to the Bank the full amount
thereof and, to the full extent necessary for the purpose, Guarantor hereby 
assigns to the Bank all of the Guarantor's rights to any and all such payments
or distributions to which Guarantor would otherwise be entitled. If the amount
so paid is greater than the guaranteed indebtedness than outstanding, the Bank
will pay the amount of the excess to the person entitled thereto.

    11.  With or without notice to Guarantor, the Bank, in its sole discretion
and at any time and from to time either before or after delivery of any notice
of revocation hereunder and in such manner and upon such terms as it considers
fit, may (a) apply any or all payments or recoveries from Debtor, from Guarantor
or from any other guarantor under this or any other instrument or realized from
any security, in such manner and order or priority as the Bank elects, to any
indebtedness of Debtor to the Bank, whether or not such indebtedness is
guaranteed hereby or is otherwise secured or is due at the time of such
application; and (b) refund to Debtor any payment received by the Bank upon any
indebtedness hereby guaranteed and payment of the amount refunded shall be fully
guaranteed hereby. Any recovery realized from any other guarantor under this or
any other instrument shall be first credited upon that portion of the
indebtedness of Debtor to the Bank which exceeds Guarantor's maximum liability,
if any, hereunder.

    12.  The amount of Guarantor's liability and all rights, powers and
remedies of the Bank hereunder and under the Credit Documents and any other
agreement now or at any time hereafter in force between the Bank and Guarantor
shall be cumulative and not alternative, and such rights, powers and remedies
shall be in addition to all rights, powers and remedies given to the Bank by
law. 

    13.  Guarantor's obligations hereunder are independent of the obligations of
Debtor and, in the event of any default hereunder, a separate action or actions
may be brought and prosecuted against Guarantor whether action is brought
against Debtor or whether Debtor is joined in any such action or actions. The
Bank may maintain successive actions for other defaults. The Bank's rights
hereunder shall not be exhausted by its exercise of any of its rights or
remedies or by any such action or by any number of successive actions until and
unless all indebtedness and obligations hereby guaranteed have been paid and
fully performed.



                                  Page 2 of 4

     14.  This is a continuing guarantee and Guarantor agrees that it shall
remain in full force until and unless Guarantor delivers to the Bank written
notice that it has been revoked as to credit granted subsequent to the effective
time of revocation as herein provided. Delivery of such notice shall be
effective by personal service upon an officer of the Bank at the originating
office of the Bank designated on the first page hereof or by mailing such notice
by certified or registered mail, return receipt requested, postage prepaid and
addressed to the Bank at the originating office designated on the first page
hereof. Regardless of how notice of revocation is given, it shall not be
effective until twelve o'clock noon Pacific Standard or Daylight Savings Time,
as the case may be, on the next succeeding Bank business day following the day
such notice is delivered, but delivery of such notice shall not affect any of
Guarantor's obligations hereunder with respect to credit granted prior to the
effective date of such revocation, nor shall it affect any of the obligations of
any other guarantor for the credit granted to Debtor hereunder. If the
originating office of the Bank designated above is not in existence at the time
notice of revocation is desired to be given, then such notice may be given in
the manner above provided by delivering the same to IMPERIAL BANK OFFICE at 9920
South La Cienega Boulevard, Inglewood, California 90301. 

     15.  Guarantor agrees to pay to the Bank without demand reasonable
attorneys' fees and all costs and other expenses which the Bank expends or
incurs in collecting or compromising any indebtedness of the Debtor, in
protecting the Bank's security under the Credit Documents or in enforcing this
guarantee against Guarantor or any other guarantor of any indebtedness hereby
guaranteed whether or not suit is filed, including, without limitation,
attorney's fees, costs and other such expenses incurred in any bankruptcy
proceeding. Guarantor warrants and represents that it is fully authorized by law
to execute this guarantee.

     16.  This guarantee shall benefit the Bank, its successors and assigns,
including the assignees of any indebtedness hereby guaranteed, and binds
Guarantor's successors and assigns. This guarantee is assignable by the Bank
with respect to all or any portion of the indebtedness and obligations
guaranteed hereunder, and, when so assigned, Guarantor shall be liable to the
assignees under this guarantee without in any manner affecting Guarantor's
liability hereunder with respect to any indebtedness or obligations retained by
the Bank. No delegation or assignment of this guarantee by any Guarantor shall
be of any force or effect or release Guarantor from any obligation hereunder.

     17.  No provision of this guarantee or right of the Bank hereunder can be
waived, nor can any Guarantor be released from his/her obligations hereunder,
except by a writing duly executed by an authorized officer of the Bank. Should
any one or more provisions of this guarantee be determined to be illegal or
unenforceable, all other provisions nevertheless shall be governed by and
construed in accordance with the laws of California, and Guarantor agrees to
submit to the jurisdiction of the Courts of California.

     18.  If more than one guarantor signs this guarantee, the obligation of all
such guarantors shall be joint and several. When the context and construction so
require, all words used in the singular shall be deemed to have been used in the
plural and the masculine shall include the feminine and neuter. Any married
person who signs this guarantee agrees that recourse may be had against separate
property for all obligations under this guarantee.

     19.  Except as provided in any other written agreement now or at any time
hereafter in force between the Bank and Guarantor, this guarantee shall
constitute the entire agreement of Guarantor with the Bank with respect to the
subject matter hereof and no representation, understanding, promise or condition
concerning the subject matter hereof shall be binding upon the Bank unless
expressed herein. Any notice to Guarantor shall be considered to have been duly
given when delivered personally or forty-eight hours after being mailed,
postage prepaid, to the address(es) set forth below or to such other address(es)
as Guarantor may from time to time designate by giving notice in the same manner
of notice to the Bank set forth in Paragraph 14 hereof.

     20.  Each of the undersigned Guarantors hereby acknowledges the receipt of
a true copy of this guarantee.

     21.  [  ] This guarantee is secured by a deed of trust dated            ,
19 , to Imperial Bancorp. as Trustee.

          security interest. Should any remittance include a payment not on an
          account, it shall be delivered to Bank and, if no event of default
          has occurred, Bank shall pay obligor the amount of such payment.

          (e)  Obligor agrees not to compromise, settle or adjust any account or
          renew or extend the time of payment thereof without Bank's prior

     8.   Obligor will insure the Collateral with Bank as loss payee in form and
amounts with companies, and against risks and liability satisfactory to Bank,
and hereby assigns such policies to Bank, agrees to deliver them to Bank at
Bank's request, and authorizes Bank to make any claim thereunder, to cancel the
insurance on Obligor's default, and to receive payment of and endorse any
instrument in payment of any loss or return premium. If Obligor should fail to
deliver the required policy or policies to the Bank, Bank may, at Obligor's cost
and expense, without any duty to do so, get and pay for insurance naming as the
Insured, at Bank's option, either both Obligor and Bank, or only Bank, and the
cost thereof shall be secured by this Security Agreement, and shall be repayable
as provided in paragraph 1 above.

     9.   Obligor will give Bank any information it requires. All information at
any time supplied to Bank by Obligor (including, but not limited to, the value
and condition of Collateral, financial statements, financing statements, and
statements made in documentary Collateral) is correct and complete, and Obligor
will notify Bank of any adverse change in such information. Obligor will
promptly notify Bank of any change of Obligor's residence, chief executive

          (a)  Endorse, collect and receive delivery or payment of instruments
          and documents constituting Collateral;
          
          (b)  Make extension agreements with respect to or affecting
          Collateral, exchange it for other Collateral, release persons liable
          thereon or take security for the payment thereof, and compromise
          disputes in connection therewith;
     
          (c)  Use or operate Collateral for the purpose of preserving
          Collateral or its value and for preserving or liquidating Collateral.

     11.  If more than one Obligor signs this Agreement, their liability is
joint and several. Any Obligor who is married agrees that recourse may be had

even if the Debt is outlawed. All Obligors waive: (a) any right to require Bank
to proceed against any Obligor before any other, or to pursue any other remedy;
(b) presentment, protest and notice of protest, demand and notice of nonpayment,
demand or performance, notice of sale, and advertisement of sale; (c) any right

part of the Debt shall immediately become due. Bank shall have all rights given
by law, and may sell, in one or more sales, Collateral in any county where Bank
has an office. Bank may purchase at such sale. Sales for cash or on credit to a
wholesaler, retailer or user of the Collateral, or at public or private auction,
are all to be considered commercially reasonable. Bank may require Obligor to
assemble the Collateral and make it available to Bank at the entrance to the
location of the Collateral, or a place designated by Bank.

          Defaults shall include:

          (a)  Any default by Obligor in the Credit Terms and Conditions
          executed by Obligor.

          (b)  Any default by National Insurance Group in any of its
          obligations to the Bank.

          (c)  Any actual or reasonably anticipated deterioration of the
          Collateral or in the market price thereof which causes it, in Bank's
          judgment, to become unsatisfactory as security.
        
          (d)  Any levy or seizure against Borrower or any of the Collateral.

          (e)  Death, termination of business, assignment for creditors,
          insolvency, appointment of receiver, or the filing of any petition
          under bankruptcy or debtor's relief laws of, by or against Obligor
          or Borrower or any guarantor of the Debt.

          (f)  Any warranty or representation which is false or is reasonably 
          believed in good faith by Bank to be false.

     13.  Bank's acceptance of partial or delinquent payments or the failure of
Bank to exercise any right or remedy shall not waive any obligation of Obligor
or Borrower or right of Bank to modify this Agreement, or waive any other
similar default.

     14.  On transfer of all or any part of the Debt, Bank may transfer all or
any part of the Collateral. Bank may deliver all or any part of the Collateral
to any Obligor at any time. Any such transfer or delivery shall discharge Bank
from all liability and responsibility with respect to such Collateral
transferred or delivered. This Agreement benefits Bank's successors and assigns
and binds Obligor's heirs, legatees, personal representatives, successors and
assigns. Obligor agrees not to assert against any assignee of Bank any claim or
defense that may exist against Bank. Time is of the essence. This Agreement and
supplementary schedules hereto contain the entire security agreement between
Bank and Obligor. Obligor will execute any additional agreements, assignments or
documents reasonably required by Bank to carry this Agreement into effect.

     15.  This Agreement shall be governed by and construed in accordance with
the laws of the State of California, to the jurisdiction of whose courts the
Obligor hereby agrees to submit. Obligor agrees that service of process may be
accompanied by any means authorized by California law. All words used herein in
the singular shall be considered to have been used in the plural where the
context and construction so require.

      (b)   If Pledgor fails faithfully to perform or observe any material
covenant or agreement herein to be performed by Pledgor and such failure has a
material adverse effect on the Collateral, and such failure continues for

compelled to resort to one or more sales to a restricted group of purchasers
who will be required to agree to acquire the Collateral for their own account,
for investment and not with a view to the further distribution or resale
thereof without restriction. Pledgor agrees that any sale(s) so made may be at
prices and other terms less favorable to Pledgor than if the Collateral were
sold to the public, and that Secured Party has no obligation to delay the sale
of the Collateral for period(s) of time necessary to permit the issuer thereof
to register the Collateral for sale to the public under any of the Securities
Laws. Pledgor agrees that negotiated sales whether for cash or credit made
under the
<PAGE>   5
foregoing circumstances shall not be deemed for that reason not to have been
made in a commercially reasonable manner. Pledgor shall cooperate with Secured
Party and shall satisfy any requirements under the Securities laws applicable
to the sale or transfer of the Collateral.
