BANK OF AMERICA                                   BUSINESS LOAN AGREEMENT
NATIONAL TRUST AND SAVINGS ASSOCIATION

--------------------------------------------------------------------------

This Agreement dated as of March 4, 1998, is between Bank of America National
Trust and Savings Association (the "Bank") and SRS Labs, Inc. (the "Borrower").

1.   LINE OF CREDIT AMOUNT AND TERMS

1.1  LINE OF CREDIT AMOUNT.

(a)  During the availability period described below.  The Bank will provide a
     line of credit to the Borrower. The amount of the line of credit (the
     "Commitment") is the lesser of:

     (i)  Ten Million Dollars ($10,000,000) or

     (ii) the loan value of the marketable securities pledged to the Bank. The
          loan value of a marketable security will be a percentage of its fair
          market value. The fair market value will be determined by the Bank
          from time to time in its sole discretion. The percentage applied to a
          particular marketable security will be set by the Bank at the time it
          is pledged to the Bank. The percentage can be charged by the Bank at
          any time for reasonable cause. The Bank's records of the applicable
          percentage will be controlling.

      If at any time the total amount of principal outstanding under the line
      of credit exceeds this limit, the Borrower will immediately either
      increase the loan value of marketable securities or other acceptable
      collateral pledged to the Bank, or reduce the total mount outstanding in
      order to comply with this limit. If any of the pledged assets are margin
      stock, the Borrower will provide the Bank a Form U-1 Purpose Statement,
      and the Bank and the Borrower will comply with the restrictions imposed
      by Regulation U of the Federal Reserve, which may require a reduction in
      the loan value of the margin stock pledged to the Bank.

      For regulatory reasons, the Bank will not accept as collateral ineligible
      Securities while they are being underwritten by BancAmerica Robertson
      Stephens, or for thirty days thereafter. BancAmerica Robertson Stephens is
      a wholly-owned subsidiary of BankAmerica Corporation, and is a registered
      broker-dealer which is permitted to underwrite and deal in certain
      ineligible Securities. "Ineligible Securities" means securities which may
      not be underwritten or dealt in by member banks of the Federal Reserve
      System under Section 16 of the Banking Act of 1933 (12 U.S.C. Section 24,
      Seventh), as amended.

(b)   This is a revolving line of credit providing for cash advances and letters
      of credit. During the availability period, the Borrower may repay
      principal amounts and reborrow them.

(c)   The Borrower agrees not to permit the outstanding principal balance of
      advances under the line of credit plus the outstanding amounts of any
      letters of credit, including amounts drawn on letters of credit and not
      yet reimbursed to exceed the Commitment.

1.2   AVAILABILITY PERIOD.  The line of credit is available between the date of
this Agreement and June 1, 2000 (the "Expiration Date") unless the Borrower is
in default.

1.3   INTEREST RATE.

(a)   Unless the Borrower elects an optional interest rate as described below,
      the interest rate is the Bank's Reference Rate.

(b)   The Reference Rate is the rate of interest publicly announced from time to
      time by the Bank in San Francisco, California, as its Reference Rate. The
      Reference Rate is set by the Bank based on various factors, including the
      Bank's costs and desired return, general economic conditions and other

                                 - 1 -
<PAGE>   2
        factors, and is used as a reference point for pricing some loans. The
        Bank may price loans to its customers at, above, or below the Reference
        Rate. Any change in the Reference Rate shall take effect at the opening
        of business on the day specified in the public announcement of a change
        in the Bank's Reference Rate.

1.4     REPAYMENT TERMS.

(a)     The Borrower will pay interest on April 1, 1998, and then monthly
        thereafter until payment in full of any principal outstanding under this
        line of credit.

(b)     The Borrower will repay in full all principal and any unpaid interest or
        other charges outstanding under this line of credit no later than the
        Expiration Date.

(c)     Any amount bearing interest at an optional interest rate (as described
        below) may be repaid at the end of the applicable interest period, which
        shall be no later than the Expiration Date.

1.5     OPTIONAL INTEREST RATES. Instead of the interest rate based on the
Bank's Reference Rate, the Borrower may elect the optional interest rates listed
below during interest periods agreed to by the Bank and the Borrower. The
optional interest rates shall be subject to the terms and conditions described
later in this Agreement. Any principal amount bearing interest at an optional
rate under this Agreement is referred to as a "Portion." The following optional
interest rates are available:

(a)     the LIBOR Rate plus 0.75 percentage point.

1.6     LETTERS OF CREDIT. This line of credit may be used for financing:

        (i)     commercial letters of credit with a maximum maturity of 120 days
                but not to extend beyond the Expiration Date. Each commercial
                letter of credit will require drafts payable at sight.

        (ii)    standby letters of credit with a maximum maturity of 360 days
                but not to extend beyond the Expiration Date.

        (iii)   The amount of letters of credit outstanding at any one time,
                (including amounts drawn on letters of credit and not yet
                reimbursed), may not exceed Two Million Dollars ($2,000,000).

The Borrower agrees:

(a)     any sum drawn under a letter of credit may, at the option of the Bank,
        be added to the principal amount outstanding under this Agreement. The
        amount will bear interest and be due as described elsewhere in this
        Agreement.

(b)     if there is a default under this Agreement, to immediately prepay and
        make the Bank whole for any outstanding letters of credit.

(c)     the issuance of any letter of credit and any amendment to a letter of
        credit is subject to the Bank's written approval and must be in form and
        content satisfactory to the Bank and in favor of a beneficiary
        acceptable to the Bank. Without limiting the foregoing, no letter of
        credit may be issued to support any obligation of the Borrower in
        connection with workers' compensation laws.

(d)     to sign the Bank's form Application and Agreement for Commercial Letter
        of Credit or Application and Agreement for Standby Letter of Credit.

(e)     to pay any issuance and/or other fees that the Bank notifies the
        Borrower will be charged for issuing and processing letters of credit
        for the Borrower.

(f)     to allow the Bank to automatically charge its checking account for
        applicable fees, discounts, and other charges.

                                     - 2 -

2.      OPTIONAL INTEREST RATES

2.1     OPTIONAL RATES. Each optional interest rate is a rate per year. Interest
will be paid on the last day of each interest period, and on the first day each
month during the interest period. At the end of any interest period, the
interest rate will revert to the rate based on the Reference Rate, unless the
Borrower has designated another optional interest rate for the Portion. No
Portion will be converted to a different interest rate during the applicable
interest period. Upon the occurrence of an event of default under this
Agreement, the Bank may terminate the availability of optional interest rates
for interest periods commencing after the default occurs.

2.2     LIBOR RATE. The election of LIBOR Rates shall be subject to the
following terms and requirements:

(a)     The interest period during which the LIBOR Rate will be in effect will
        be one, two, three, four, five, six, seven, eight, nine, ten, eleven, or
        twelve months. The first day of the interest period must be a day other
        than a Saturday or a Sunday on which the Bank is open for business in
        California, New York and London and dealing in offshore dollars (a
        "LIBOR Banking Day"). The last day of the interest period and the actual
        number of days during the interest period will be determined by the Bank
        using the practices of the London inter-bank market.

(b)     Each LIBOR Rate Portion will be for an amount not less than the
        following:

        (i)     for interest periods of four months or longer, Five Hundred
                Thousand Dollars ($500,000).

        (ii)    for interest periods of one, two or three months, One Million
                Dollars ($1,000,000).

(c)     The "LIBOR Rate" means the interest rate determined by the following
        formula, rounded upward to the nearest 1/100 of one percent. (All
        amounts in the calculation will be determined by the Bank as of the
        first day of the interest period.)

                 LIBOR Rate =   London Inter-Bank Offered Rate
                              ----------------------------------
                                 (1.00 - Reserve Percentage)

        Where,

        (i)     "London Inter-Bank Offered Rate" means the interest rate at
                which the Bank's London Branch, London, Great Britain, would
                offer U.S. dollar deposits for the applicable interest period to
                other major banks in the London inter-bank market at
                approximately 11:00 a.m. London time two (2) London Banking Days
                before the commencement of the interest period. A "London
                Banking Day" is a day on which the Bank's London Branch is open
                for business and dealing in offshore dollars.

        (ii)    "Reserve Percentage" means the total of the maximum reserve
                percentages for determining the reserves to be maintained by
                member banks of the Federal Reserve System for Eurocurrency
                Liabilities, as defined in Federal Reserve Board Regulation D,
                rounded upward to the nearest 1/100 of one percent. The
                percentage will be expressed as a decimal, and will include, but
                not be limited to, marginal, emergency, supplemental, special,
                and other reserve percentages.

(d)     The Borrower shall irrevocably request a LIBOR Rate Portion no later
        than 12:00 noon San Francisco time on the LIBOR Banking Day preceding
        the day on which the London Inter-Bank Offered Rate will be set, as
        specified above. For example, if there are no intervening holidays or
        weekend days in any of the relevant locations, the request must be made
        at least three days before the LIBOR Rate takes effect.

(e)     The Borrower may not elect a LIBOR Rate with respect to any principal
        amount which is scheduled to be repaid before the last day of the
        applicable interest period.

(f)     Each prepayment of a LIBOR Rate Portion, whether voluntary, by reason of
        acceleration or otherwise, will be accompanied by the amount of accrued
        interest on the amount prepaid and a prepayment fee as described below.
        A "prepayment" is a payment of an amount on a date earlier than the
        scheduled

                                     - 3 -
<PAGE>   4
     payment date for such amount as required by this Agreement. The prepayment
     fee shall be equal to the amount (if any) by which:

     (i)  the additional interest which would have been payable during the
          interest period on the amount prepaid had it not been prepaid, exceeds

     (ii) the interest which would have been recoverable by the Bank by placing
          the amount prepaid on deposit in the domestic certificate of deposit
          market, the eurodollar deposit market, or other appropriate money
          market selected by the Bank, for a period starting on the date on
          which it was prepaid and ending on the last day of the interest period
          for such Portion (or the scheduled payment date for the amount
          prepaid, if earlier).

(g)  The Bank will have no obligation to accept an election for a LIBOR Rate
     Portion if any of the following described events has occurred and is
     continuing:

     (i)  Dollar deposits in the principal amount, and for periods equal to the
          interest period, of a LIBOR Rate Portion are not available in the
          London inter-bank market; or

     (ii) the LIBOR Rate does not accurately reflect the cost of a LIBOR Rate
          Portion.

3.   EXPENSES

3.1  EXPENSES. The Borrower agrees to immediately repay the Bank for expenses
that include, but are not limited to, filing, recording and search fees and
documentation fees.

3.2  REIMBURSEMENT COSTS.

(a)  The Borrower agrees to reimburse the Bank for any expenses it incurs in the
     preparation of this Agreement and any agreement or instrument required by
     this Agreement. Expenses include, but are not limited to, reasonable
     attorney's fees, including any allocated costs of the Bank's in-house
     counsel.

(b)  The Borrower agrees to reimburse the Bank for the cost of periodic audits
     of the collateral securing this Agreement, at such intervals as the Bank
     may reasonably require. The audits may be performed by employees of the
     Bank or by independent auditors.

4.   COLLATERAL

4.1  PERSONAL PROPERTY.  The Borrower's obligations to the Bank under this
Agreement will be secured by personal property the Borrower now owns or will
own in the future as listed below. The collateral is further defined in
security agreement(s) executed by the Borrower. In addition, all personal
property collateral securing this Agreement shall also secure all other present
and future obligations of the Borrower to the Bank (excluding any consumer
credit covered by the federal Truth in Lending law, unless the Borrower has
otherwise agreed in writing). All personal property collateral securing any
other present or future obligations of the Borrower to the Bank shall also
secure this Agreement.

Account number 3600014 maintained by Salomon Brothers Asset Management, Inc.
("Bailee") in the name of the Borrower, and all successor and replacement
accounts, regardless of the numbers of such accounts or the offices at which
such accounts are maintained (the "Accounts") and all rights of Borrower
against Bailee in connection with the Account.

5.   DISBURSEMENTS, PAYMENTS AND COSTS

5.1  REQUESTS FOR CREDIT. Each request for an extension of credit will be made
in writing in a manner acceptable to the Bank, or by another means acceptable
to the Bank.

5.2  DISBURSEMENTS AND PAYMENTS. Each disbursement by the Bank and each payment
by the Borrower will be:

(a)  made at the Bank's branch (or other location) selected by the Bank from
time to time;

                                     - 4 -
<PAGE>   5
(b)  made for the account of the Bank's branch selected by the Bank from time
     to time;

(c)  made in immediately available funds, or such other type of funds selected
     by the Bank;

(d)  evidenced by records kept by the Bank. In addition, the Bank may, at its
     discretion, require the Borrower to sign one or more promissory notes.

5.3  TELEPHONE AND TELEFAX AUTHORIZATION.

(a)  The Bank may honor telephone or telefax instructions for advances or
     repayments or for the designation of optional interest rates and telefax
     requests for the issuance of letters of credit given by any one of the
     individuals authorized to sign loan agreements on behalf of the Borrower,
     or any other individual designated by any one of such authorized signers.

(b)  Advances will be deposited in and repayments will be withdrawn from the
     Borrower's account number 14588-26464, or such other of the Borrower's
     accounts with the Bank as designated in writing by the Borrower.

(c)  The Borrower indemnifies and excuses the Bank (including its officers,
     employees, and agents) from all liability, loss, and costs in connection
     with any act resulting from telephone or telefax instructions it reasonably
     believes are made by any individual authorized by the Borrower to give such
     instructions. This indemnity and excuse will survive this Agreement's
     termination.

5.4  DIRECT DEBIT (PRE-BILLING).

(a)  The Borrower agrees that the Bank will debit the Borrower's deposit account
     number 14588-26464, or such other of the Borrower's accounts with the Bank
     as designated in writing by the Borrower (the "Designated Account") on the
     date each payment of principal and interest and any fees from the Borrower
     becomes due (the "Due Date"). If the Due Date is not a banking day, the
     Designated Account will be debited on the next banking day.

(b)  Approximately 10 days prior to each Due Date, the Bank will mail to the
     Borrower a statement of the amounts that will be due on that Due Date (the
     "Billed Amount"). The calculation will be made on the assumption that no
     new extensions of credit or payments will be made between the date of the
     billing statement and the Due Date, and that there will be no changes in
     the applicable interest rate.

(c)  The Bank will debit the Designated Account for the Billed Amount,
     regardless of the actual amount due on that date (the "Accrued Amount").

     If the Billed Amount debited to the Designated Account differs from the
     Accrued Amount, the discrepancy will be treated as follows:

     (i)  If the Billed Amount is less than the Accrued Amount, the Billed
          Amount for the following Due Date will be increased by the amount of
          the discrepancy. The Borrower will not be in default by reason of any
          such discrepancy.

     (ii) If the Billed Amount is more than the Accrued Amount, the Billed
          Amount for the following Due Date will be decreased by the amount of
          the discrepancy.

     Regardless of any such discrepancy, interest will continue to accrue based
     on the actual amount of principal outstanding without compounding. The Bank
     will not pay the Borrower interest on any overpayment.

(d)  The Borrower will maintain sufficient funds in the Designated Account to
     cover each debit. If there are insufficient funds in the Designated Account
     on the date the Bank enters any debit authorized by this Agreement, the
     debit will be reversed.

5.5  BANKING DAYS.  Unless otherwise provided in this Agreement, a banking day
is a day other than a Saturday or a Sunday on which the Bank is open for
business in California. For amounts bearing interest at an


                                     - 5 -


<PAGE>   6
offshore rate (if any), a banking day is a day other than a Saturday or a
Sunday on which the Bank is open for business in California and dealing in
offshore dollars. All payments and disbursements which would be due on a day
which is not a banking day will be due on the next banking day. All payments
received on a day which is not a banking day will be applied to the credit on
the next banking day.

5.6  TAXES.

(a)  If any payments to the Bank under this Agreement are made from outside the
     United States, the Borrower will not deduct any foreign taxes from any
     payments it makes to the Bank. If any such taxes are imposed on any payment
     made by the Borrower (including payments under this paragraph), the
     Borrower will pay the taxes and will also pay to the Bank, at the time
     interest is paid, any additional amount which the Bank specifies as
     necessary to preserve the after-tax yield the Bank would have received if
     such taxes had not been imposed. The Borrower will confirm that it has paid
     the taxes by giving the Bank official tax receipts (or notarized copies)
     within 30 days after the due date.

(b)  Payments made by the Borrower to the Bank will be made without deduction of
     United States withholding or similar taxes. If the Borrower is required to
     pay U.S. withholding taxes, the Borrower will pay such taxes in addition to
     the amounts due to the Bank under this Agreement. If the Borrower fails to
     make such tax payments when due, the Borrower indemnifies the Bank against
     any liability for such taxes, as well as for any related interest,
     expenses, additions to tax, or penalties asserted against or suffered by
     the Bank with respect to such taxes.

5.7  ADDITIONAL COSTS.   The Borrower will pay the Bank, on demand, for the
Bank's costs or losses arising from any statute or regulation, or any request
or requirement of a regulatory agency which is applicable to all national banks
or a class of all national banks. The costs and losses will be allocated to the
loan in a manner determined by the Bank, using any reasonable method. The costs
include the following:

(a)  any reserve or deposit requirements; and

(b)  any capital requirements relating to the Bank's assets and commitments for
     credit.

5.8  INTEREST CALCULATION.    Except as otherwise stated in this Agreement, all
interest and fees, if any, will be computed on the basis of a 360-day year and
the actual number of days elapsed. This results in more interest or a higher
fee than if a 365-day year is used. Instalments of principal which are not paid
when due under this Agreement shall continue to bear interest until paid.

5.9  DEFAULT RATE.  Upon the occurrence and during the continuation of any
default under this Agreement, principal amounts outstanding under this
Agreement will at the option of the Bank bear interest at a rate which is 2.00
percentage point(s) higher than the rate of interest otherwise provided under
this Agreement. This will not constitute a waiver of any default.

5.10 INTEREST COMPOUNDING.    At the Bank's sole option in each instance, any
interest, fees or costs which are not paid when due under this Agreement shall
bear interest from the due date at the Bank's Reference Rate plus 2.00
percentage points. This may result in compounding of interest.

6.   CONDITIONS

The Bank must receive the following items, in form and content acceptable to
the Bank, before it is required to extend any credit to the Borrower under this
Agreement:

6.1  AUTHORIZATIONS.     Evidence that the execution, delivery and performance

7.15    YEAR 2000 COMPLIANCE.  The Borrower has conducted a comprehensive
review and assessment of the Borrower's computer applications and made inquiry
of the Borrower's key suppliers, vendors and customers with respect to the "year
2000 problem" (that is, the risk that computer applications may not be able to
properly perform date-sensitive functions after December 31, 1999) and, based
on that review and inquiry, the Borrower does not believe the year 2000 problem
will result in a material adverse change in the Borrower's business condition
(financial or otherwise), operations, properties or prospects, or ability to
repay the credit.

     Agreement.

about the Borrower with actual or potential participants or assignees; provided

or the loan is assigned, the purchaser will have the right of set-off against
the Borrower.

10.4  ARBITRATION.

(a)   This paragraph concerns the resolution of any controversies or claims
between the Borrower and the Bank, including but not limited to those that
arise from:

      (i)  This Agreement (including any renewals, extensions or modifications
of this Agreement);

                                      -10-

<PAGE>   11
        (ii)    Any document, agreement or procedure related to or delivered in
                connection with this Agreement;

        (iii)   Any violation of this Agreement; or

        (iv)    Any claims for damages resulting from any business conducted
                between the Borrower and the Bank, including claims for injury
                to persons, property or business interests (torts).

(b)     At the request of the Borrower or the Bank, any such controversies or
        claims will be settled by arbitration in accordance with the United
        States Arbitration Act. The United States Arbitration Act will apply
        even though this Agreement provides that it is governed by California
        law.

(c)     Arbitration proceedings will be administered by the American Arbitration
        Association and will be subject to its commercial rules of arbitration.

(d)     For purposes of the application of the statute of limitations, the
        filing of an arbitration pursuant to this paragraph is the equivalent of
        the filing of a lawsuit, and any claim or controversy which may be
        arbitrated under this paragraph is subject to any applicable statute of
        limitations. The arbitrators will have the authority to decide whether
        any such claim or controversy is barred by the statute of limitations
        and, if so, to dismiss the arbitration on that basis.

(e)     If there is a dispute as to whether an issue is arbitrable, the
        arbitrators will have the authority to resolve any such dispute.

(f)     The decision that results from an arbitration proceeding may be
        submitted to any authorized court of law to be confirmed and enforced.

(g)     The procedure described above will not apply if the controversy or
        claim, at the time of the proposed submission to arbitration, arises
        from or relates to an obligation to the Bank secured by real property
        located in California. In this case, both the Borrower and the Bank must
        consent to submission of the claim or controversy to arbitration. If
        both parties do not consent to arbitration, the controversy or claim
        will be settled as follows:

        (i)     The Borrower and the Bank will designate a referee (or a panel
                of referees) selected under the auspices of the American
                Arbitration Association in the same manner as arbitrators are
                selected in Association-sponsored proceedings;

        (ii)    The designated referee (or the panel of referees) will be
                appointed by a court as provided in California Code of Civil
                Procedure Section 638 and the following related sections;

        (iii)   The referee (or the presiding referee of the panel) will be an
                active attorney or a retired judge; and

        (iv)    The award that results from the decision of the referee (or the
                panel) will be entered as a judgment in the court that appointed
                the referee, in accordance with the provisions of California
                Code of Civil Procedure Sections 644 and 645.

(h)     This provision does not limit the right of the Borrower or the Bank to:

        (i)     exercise self-help remedies such as setoff;

        (ii)    foreclose against or sell any real or personal property
                collateral; or

        (iii)   act in a court of law, before, during or after the arbitration
                proceeding to obtain;

                (A)     an interim remedy; and/or

                (B)     additional or supplementary remedies.


                                      -11-

<PAGE>   12
(i)   The pursuit of or a successful action for interim, additional or
      supplementary remedies, or the filing of a court action, does not
      constitute a waiver of the right of the Borrower or the Bank, including
      the suing party, to submit the controversy or claim to arbitration if the
      other party contests the lawsuit. However, if the controversy or claim
      arises from or relates to an obligation to the Bank which is secured by
      real property located in California at the time of the proposed submission
      to arbitration, this right is limited according to the provision above
      requiring the consent of both the Borrower and the Bank to seek resolution
      through arbitration.

(j)   If the Bank forecloses against any real property securing this Agreement,
      the Bank has the option to exercise the power of sale under the deed of
      trust or mortgage, or to proceed by judicial foreclosure.

10.5  SEVERABILITY; WAIVERS. If any part of this Agreement is not enforceable,
the rest of the Agreement may be enforced. The Bank retains all rights, even if
it makes a loan after default. If the Bank waives a default, it may enforce a
later default. Any consent or waiver under this Agreement must be in writing.

10.6  ADMINISTRATION COSTS. The Borrower shall pay the Bank for all reasonable
costs incurred by the Bank in connection with administering this Agreement.

10.7  ATTORNEYS' FEES. The Borrower shall reimburse the Bank for any reasonable
costs and attorneys' fees incurred by the Bank in connection with the
enforcement or preservation of any rights or remedies under this Agreement and
any other documents executed in connection with this Agreement, and in
connection with any amendment, waiver, "workout" or restructuring under this
Agreement. In the event of a lawsuit or arbitration proceeding, the prevailing
party is entitled to recover costs and reasonable attorneys' fees incurred in
connection with the lawsuit or arbitration proceeding, as determined by the
court or arbitrator. In the event that any case is commenced by or against the
Borrower under the Bankruptcy Code (Title 11, United States Code) or any similar
or successor statute, the Bank is entitled to recover costs and reasonable
attorneys' fees incurred by the Bank related to the preservation, protection, or
enforcement of any rights of the Bank in such a case. As used in this paragraph,
"attorneys' fees" includes the allocated costs of the Bank's in-house counsel.

10.8  ONE AGREEMENT. This Agreement and any related security or other agreements
required by this Agreement, collectively:

(a)   represent the sum of the understandings and agreements between the Bank
      and the Borrower concerning this credit; and

(b)   replace any prior oral or written agreements between the Bank and the
      Borrower concerning this credit; and

(c)   are intended by the Bank and the Borrower as the final, complete and
      exclusive statement of the terms agreed to by them.

In the event of any conflict between this Agreement and any other agreements
required by this Agreement, this Agreement will prevail.

10.9  INDEMNIFICATION. The Borrower will indemnify and hold the Bank harmless
from any loss, liability, damages, judgments, and costs of any kind relating to
or arising directly or indirectly out of (a) this Agreement or any document
required hereunder, (b) any credit extended or committed by the Bank to the
Borrower hereunder, and (c) any litigation or proceeding related to or arising
out of this Agreement, any such document, or any such credit. This indemnity
includes but is not limited to attorneys' fees (including the allocated cost of
in-house counsel). This indemnity extends to the Bank, its parent, subsidiaries
and all of their directors, officers, employees, agents, successors, attorneys,
and assigns. This indemnity will survive repayment of the Borrower's obligations
to the Bank. All sums due to the Bank hereunder shall be obligations of the
Borrower, due and payable immediately without demand.

10.10 NOTICES. All notices required under this Agreement shall be personally
delivered or sent by first class mail, postage prepaid, to the addresses on the
signature page of this Agreement, or to such other addresses as the Bank and the
Borrower may specify from time to time in writing.

10.11 HEADINGS. Article and paragraph headings are for reference only and shall
not affect the interpretation or meaning of any provisions of this Agreement.
