Dear Sir:

        This letter is to confirm that Wells Fargo Bank, National Association
("Bank"), subject to all terms and conditions contained herein, has agreed to

which Bank will make advances to Borrower from time to time up to and including
May 1, 1998, not to exceed at any time the maximum principal amount of Ten
Million Dollars ($10,000,000.00) ("Line of Credit"), the proceeds of which
shall be used to support Borrower's working capital requirements.

I.  CREDIT TERMS:

    1.  LINE OF CREDIT:

        (a)  Line of Credit Note.  Borrower's obligation to repay advances
under the Line of Credit shall be evidenced by a promissory note substantially

which are incorporated herein by this reference.

        (b)  Borrowing and Repayment.  Borrower may from time to time during
the term of the Line of Credit borrow, partially or wholly repay its
outstanding borrowings, and reborrow, subject to all of the limitations, terms
and conditions contained herein or in the Line of Credit Note; provided
however, that the total outstanding borrowings under the Line of Credit shall
not at any time exceed the maximum principal amount available thereunder, as
set forth above.

II. INTEREST/FEES:

    1.  Interest.  The outstanding principal balance of the Line of Credit shall
bear interest at the rate of interest set forth in the Line of Credit Note.

        2.  Computation and Payment.  Interest shall be computed on the basis
of a 360-day year, actual days elapsed. Interest shall be payable at the times
and place set forth in the Line of Credit Note.

        3.  Commitment Fee.  Borrower shall pay to Bank a non-refundable
commitment fee for the Line of Credit equal to $13,000.00, which fee shall be
due and payable in full upon execution of this letter.

III.    REPRESENTATIONS AND WARRANTIES:

        Borrower makes the following representations and warranties to Bank,
which representations and warranties shall survive the execution of this letter
and shall continue in full force and effect until the full and final payment,
and satisfaction and discharge, of all obligations of Borrower to Bank subject
to this letter.

        1.  Legal Status.  Borrower is a corporation, duly organized and
existing and in good standing under the laws of the state of California, and is
qualified or licensed to do business in all jurisdictions in which such
qualification or licensing is required or in which the failure to so qualify or
to be so licensed could have a material adverse effect on Borrower.

        2.  Authorization and Validity.  This letter, the Line of Credit Note,
and each other document, contract or instrument deemed necessary by Bank to
evidence any extension of credit to Borrower pursuant to the terms and
conditions hereof, or now or at any time hereafter required by or delivered to
Bank in connection with this letter (collectively, the "Loan Documents") have
been duly authorized, and upon their execution and delivery in accordance with
the provisions hereof will constitute legal, valid and binding agreements and
obligations of Borrower or the party which executes the same, enforceable in
accordance with their respective terms.

        3.  No Violation.  The execution, delivery and performance by Borrower
of each of the Loan Documents do not violate any provision of any law or
regulation, or contravene any provision of the Articles of Incorporation or
By-Laws of Borrower, or result in a breach of or constitute a default under any
contract, obligation, indenture or other instrument to which Borrower is a
party or by which Borrower may be bound.

        4.      Litigation.  There are no pending, or to the best of Borrower's
knowledge threatened, actions, claims, investigations, suits or proceedings by
or before any governmental authority, arbitrator, court or administrative
agency which could have a material adverse effect on the financial condition or
operation of Borrower other than those disclosed by Borrower to Bank in writing 
prior to the date hereof.

        5.      Correctness of Financial Statement.  The financial statement of
Borrower dated December 31, 1996, a true copy of which has been delivered by
Borrower to Bank prior to the date hereof, (a) is complete and correct and
presents fairly the financial condition of Borrower, (b) discloses all
liabilities of Borrower that are required to be reflected or reserved against
under generally accepted accounting principles, whether liquidated or
unliquidated, fixed or contingent, and (c) has been prepared in accordance with
generally accepted accounting principles consistently applied.  Since the date
of such financial statement there has been no material adverse change in the
financial condition of Borrower, nor has Borrower mortgaged, pledged, granted a
security interest in or otherwise encumbered any of its assets or properties
except in favor of Bank or as otherwise permitted by Bank in writing.

        6.      Income Tax Returns.  Borrower has no knowledge of any pending
assessments or adjustments of its income tax payable with respect to any year.

        7.      No Subordination.  There is no agreement, indenture, contract
or instrument to which Borrower is a party or by which Borrower may be bound
that requires the subordination in right of payment of any of Borrower's
obligations subject to this letter to any other obligation of Borrower.

        8.      Permits, Franchises.  Borrower possesses, and will hereafter
possess, all permits, consents, approvals, franchises and licenses required
and all rights to trademarks, trade names, patents and fictitious names, if
any, necessary to enable it to conduct the business in which it is now engaged
in compliance with applicable law.

        9.      ERISA.  Borrower is in compliance in all material respects with
all applicable provisions of the Employee Retirement Income Security Act of
1974, as amended or recodified from time to time ("ERISA"); Borrower has not
violated any provision of any defined employee pension benefit plan (as defined
in ERISA) maintained or contributed to by Borrower (each, a "Plan"); no
Reportable Event, as defined in ERISA, has occurred and is continuing with
respect to any Plan initiated by Borrower;
   4

Page 4


Borrower has met its minimum funding requirements under ERISA with respect to
each Plan; and each Plan will be able to fulfill its benefit obligations as
they come due in accordance with the Plan documents and under generally
accepted accounting principles.

        10.     Other Obligations.  Borrower is not in default on any
obligation for borrowed money, any purchase money obligation or any other
material lease, commitment, contract, instrument or obligation.

        11.     Environmental Matters.  Except as disclosed by Borrower to Bank
in writing prior to the date hereof, Borrower is in compliance in all material
respects with all applicable federal or state environmental, hazardous waste,
health and safety statutes, and any rules or regulations adopted pursuant
thereto, which govern or affect any of Borrower's operations and/or properties,
including without limitation, the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, the Superfund Amendments and
Reauthorization Act of 1986, the Federal Resource Conservation and Recovery Act
of 1976, and the Federal Toxic Substances Control Act, as any of the same may be
amended, modified or supplemented from time to time.  None of the operations of
Borrower is the subject of any federal or state investigation evaluating whether
any remedial action involving a material expenditure is needed to respond to a
release of any toxic or hazardous waste or substance into the environment.
Borrower has no material contingent liability in connection with any release of
any toxic or hazardous waste or substance into the environment.

IV.     CONDITIONS:

        1.      Conditions of Initial Extension of Credit.  The obligation of
Bank to extend any credit contemplated by this letter is subject to fulfillment
to Bank's satisfaction of all of the following conditions:

affect or operate as a waiver of such right, power or remedy; nor shall any
single or partial exercise of any such right, power or remedy preclude, waive or

other person) relating to any Borrower or any other person or entity.

        3.  Successors, Assignment.  This letter shall be binding upon and inure
to the benefit of the heirs, executors, administrators, legal representatives,

Bank reserves the right to sell, assign, transfer, negotiate or grant
participations in all or any part of, or any interest in, Bank's rights and
benefits under each of the Loan Documents. In connection therewith Bank may

        4.  Entire Agreement; Amendment.  This letter and the other Loan

party beneficiary of, or have any direct or indirect cause of action or claim in
connection with, this letter or any other of the Loan Documents to which it is
not a party.

        6.  Severability of Provisions.  If any provision of this letter shall
be prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity without

        8.  Arbitration.

        (a)  Arbitration.  Upon the demand of any party, any Dispute shall be

with the terms of this letter. A "Dispute" shall mean any action, dispute, claim
or controversy of
   11
Intevac, Inc.
April 30, 1997
Page 11


any kind, whether in contract or tort, statutory or common law, legal or
equitable, now existing or hereafter arising under or in connection with, or in
any way pertaining to, any of the Loan Documents, or any past, present or future
extensions of credit and other activities, transactions or obligations of any
kind related directly or indirectly to any of the Loan Documents, including
without limitation, any of the foregoing arising in connection with the exercise
of any self-help, ancillary or other remedies pursuant to any of the Loan
Documents. Any party may by summary proceedings bring an action in court to
compel arbitration of a Dispute. Any party who fails or refuses to submit to
arbitration following a lawful demand by any other party shall bear all costs
and expenses incurred by such other party in compelling arbitration of any
Dispute.

        (b)  Governing Rules.  Arbitration proceedings shall be administered by
the American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon in accordance with the AAA Commercial
Arbitration Rules. All Disputes submitted to arbitration shall be resolved in
accordance with the Federal Arbitration Act (Title 9 of the United States Code),
notwithstanding any conflicting choice of law provision in any of the Loan
Documents. The arbitration shall be conducted at a location in California
selected by the AAA or other administrator. If there is any inconsistency
between the terms hereof and any such rules, the terms and procedures set forth
herein shall control. All statutes of limitation applicable to any Dispute shall
apply to any arbitration proceeding. All discovery activities shall be expressly
limited to matters directly relevant to the Dispute being arbitrated. Judgment
upon any award rendered in an arbitration may be entered in any court having
jurisdiction; provided however, that nothing contained herein shall be deemed to
be a waiver by any party that is a bank of the protections afforded to it under
12 U.S.C. Section 91 or any similar applicable state law.

        (c)     No Waiver; Provisional Remedies, Self-Help and Foreclosure.  No
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a
   12
Intevac, Inc.
April 30, 1997
Page 12


court of competent jurisdiction before, after or during the pendency of any
arbitration or other proceeding. The exercise of any such remedy shall not waive
the right of any party to compel arbitration or reference hereunder.

        (d)     Arbitrator Qualifications and Powers; Awards.  Arbitrators must
be active members of the California State Bar or retired judges of the state or
federal judiciary of California, with expertise in the substantive law
applicable to the subject matter of the Dispute. Arbitrators are empowered to
resolve Disputes by summary rulings in response to motions filed prior to the
final arbitration hearing. Arbitrators (i) shall resolve all Disputes in
accordance with the substantive law of the state of California, (ii) may grant
any remedy or relief that a court of the state of California could order or
grant within the scope hereof and such ancillary relief as is necessary to make
effective any award, and (iii) shall have the power to award recovery of all
costs and fees, to impose sanctions and to take such other actions as they deem
necessary to the same extent a judge could pursuant to the Federal Rules of
Civil Procedure, the California Rules of Civil Procedure or other applicable
law. Any Dispute in which the amount in controversy is $5,000,000 or less shall
be decided by a single arbitrator who shall not render an award of greater than
$5,000,000 (including damages, costs, fees and expenses). By submission to a
single arbitrator, each party expressly waives any right or claim to recover
more than $5,000,000. Any Dispute in which the amount in controversy exceeds
$5,000,000 shall be decided by majority vote of a panel of three arbitrators;
provided however, that all three arbitrators must actively participate in all
hearings and deliberations.

        (e)     Judicial Review.  Notwithstanding anything herein to the
contrary, in any arbitration in which the amount in controversy exceeds
$25,000,000, the arbitrators shall be required to make specific, written
findings of fact and conclusions of law. In such arbitrations (i) the
arbitrators shall not have the power to make any award which is not supported by
substantial evidence or which is based on legal error, (ii) an award shall not
be binding upon the parties unless the findings of fact are supported by
substantial evidence and the conclusions of law are not erroneous under the
substantive law of the state of California, and (iii) the parties shall have in
addition to the grounds referred to in the Federal Arbitration Act for vacating,
modifying or correcting an award the right to judicial
   13
Intevac, Inc.
April 30, 1997
Page 13


review of (A) whether the findings of fact rendered by the arbitrators are
supported by substantial evidence, and (B) whether the conclusions of law are
erroneous under the substantive law of the state of California.  Judgment
confirming an award in such a proceeding may be entered only if a court
determines the award is supported by substantial evidence and not based on legal
error under the substantive law of the state of California.

        (f)     Real Property Collateral; Judicial Reference.  Notwithstanding
anything herein to the contrary, no Dispute shall be submitted to arbitration
if the Dispute concerns indebtedness secured directly or indirectly, in whole
or in part, by any real property unless (i) the holder of the mortgage, lien or
security interest specifically elects in writing to proceed with the
arbitration, or (ii) all parties to the arbitration waive any rights or
benefits that might accrue to them by virtue of the single action rule statute
of California, thereby agreeing that all indebtedness and obligations of the
parties, and all mortgages, liens and security interests securing such
indebtedness and obligations, shall remain fully valid and enforceable.  If any
such Dispute is not submitted to arbitration, the Dispute shall be referred to
a referee in accordance with California Code of Civil Procedure Section 638 et
seq., and this general reference agreement is intended to be specifically
enforceable in accordance with said Section 638.  A referee with the
qualifications required herein for arbitrators shall be selected pursuant to the
AAA's selection procedures.  Judgment upon the decision rendered by a referee
shall be entered in the court in which such proceeding was commenced in
accordance with California Code of Civil Procedure Sections 644 and 645.

        (g)     Miscellaneous.  To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA.  No arbitrator or other party to an arbitration proceeding may disclose
the existence, content or results thereof, except for disclosures of

WELLS FARGO BANK                                  REVOLVING LINE OF CREDIT NOTE
- --------------------------------------------------------------------------------

$10,000,000.00                                              San Jose, California
                                                                  April 30, 1997


        FOR VALUE RECEIVED, the undersigned INTEVAC, INC. ("Borrower") promises
to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION ("Bank") at its
office at Santa Clara Valley RCBO, 121 Park Center Plaza 3rd Flr, San Jose, CA
95115, or at such other place as the holder hereof may designate, in lawful
money of the United States of America and in immediately available funds, the
principal sum of $10,000,000.00, or so much thereof as may be advanced and be
outstanding, with interest thereon, to be computed on each advance from the date
of its disbursement as set forth herein.

DEFINITIONS:

        As used herein, the following terms shall have the meanings set forth
after each, and any other term defined in this Note shall have the meaning set
forth at the place defined:

        (a)     "Business Day" means any day except a Saturday, Sunday or any
other day on which commercial banks in California are authorized or required by
law to close.

        (b)     "Fixed Rate Term" means a period commencing on a Business Day
and continuing for 1, 2 or 3 months, as designated by Borrower, during which all
or a portion of the outstanding principal balance of this Note bears interest
determined in relation to LIBOR; provided however, that no Fixed Rate Term may
be selected for a principal amount less than $500,000.00; and provided further,
that no Fixed Rate Term shall extend beyond the scheduled maturity date
hereof.  If any Fixed Rate Term would end on a day which is not a Business Day,
the such Fixed Rate Term shall be extended to the next succeeding Business Day.

        (c)     "LIBOR" means the rate per annum (rounded upward, if necessary,
to the nearest whole 1/8 of 1%) determined by dividing Base LIBOR by a
percentage equal to 100% less any LIBOR Reserve Percentage.


                (i)     "Base LIBOR" means the rate per annum for United States
dollar deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the
understanding that such rate is quoted by Bank for the purpose of calculating
effective rates of interest for loans making reference thereto, on the first day
of a Fixed Rate Term for delivery of funds on said date for a period of time
approximately equal to the number of days in such Fixed Rate Term and in an
amount approximately equal to the principal amount to which such Fixed Rate Term
applies.  Borrower understands and agrees that Bank may base its quotation of
the Inter-Bank Market Offered Rate upon such offers or other market indicators
of the Inter-Bank Market as Bank in its discretion deems appropriate including,
but not limited to, the rate offered for U.S. dollar deposits on the London
Inter-Bank Market. 

                (ii)    "LIBOR Reserve Percentage" means the reserve percentage
prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for "Eurocurrency Liabilities" (as defined in Regulation D of the
Federal Reserve Board, as amended), adjusted by Bank for expected changes in
such reserve percentage during the applicable Fixed Rate Term.

        (d)     "Prime Rate" means at any time the rate of interest most
recently announced within Bank at its principal office as its Prime Rate, with
the understanding that the Prime Rate is one of Bank's base rates and serves as
the basis upon which effective rates of interest are calculated for those loans
making reference thereto, and is evidenced by the recording thereof after its
announcement in such internal publication or publications as Bank may designate.

INTEREST:

        (a)     Interest.  The outstanding principal balance of this Note shall
bear interest (computed on the basis of a 360-day year, actual days elapsed)
either (i) at a fluctuating rate per annum equal to the Prime Rate in effect
from time to time, or (ii) at a fixed rate per annum determined by Bank to be
1.75000% above LIBOR in effect on the first day of the applicable Fixed Rate
Term.  When interest is determined in relation to the Prime Rate, each change in
the rate of interest hereunder shall become effective on the date each Prime
Rate change is announced within Bank.  With respect to each LIBOR selection
option selected hereunder, Bank is hereby authorized to note the date, principal
amount, interest rate and Fixed Rate Term applicable thereto and any payments
made thereon on Bank's books and records (either manually or by electronic
entry) and/or on any schedule attached to this Note, which notations shall be
prima facie evidence of the accuracy of the information noted.

        (b)     Selection of Interest Rate Options.  At any time any portion of
this Note bears interest determined in relation to LIBOR, it may be continued by
Borrower at the end of the Fixed Rate Term applicable thereto so that all or a
portion thereof bears interest determined in relation to the Prime Rate or to
LIBOR for a new Fixed Rate Term designated by Borrower.  At any time any portion
of this Note bears interest determined in relation to the Prime Rate, Borrower
may convert all or a portion thereof so that it bears interest determined in
relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as
Borrower requests an advance hereunder or wishes to select a LIBOR option for
all or portion of the outstanding principal balance hereof, and at the end of
each Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the
interest rate option selected by Borrower; (ii) the






Revolving Line of Credit Note (08/96), Page 1
   20
principal amount subject thereto; and (iii) for each LIBOR selection, the length
of the applicable Fixed Rate Term. Any such notice may be given by telephone so
long as, with respect to each LIBOR selection, (A) Bank receives written
confirmation from Borrower not later than 3 Business Days after such telephone
notice is given, and (B) such notice is given to Bank prior to 10:00 a.m.,
California time, on the first day of the Fixed Rate Term. For each LIBOR option
requested hereunder, Bank will quote the applicable fixed rate to Borrower at
approximately 10:00 a.m., California time, on the first day of the Fixed Rate
Term. If Borrower does not immediately accept the rate quoted by Bank, any
subsequent acceptance by Borrower shall be subject to a redetermination by Bank
of the applicable fixed rate; provided however, that if Borrower fails to accept
any such rate by 11:00 a.m., California time, on the Business Day such quotation
is given, then the quoted rate shall expire and Bank shall have no obligation to
permit a LIBOR option to be selected on such day. If no specific designation of
interest is made at the time any advance is requested hereunder or at the end of
any Fixed Rate Term, Borrower shall be deemed to have made a Prime Rate interest
selection for such advance or the principal amount to which such Fixed Rate Term
applied.

        (c)     Additional LIBOR Provisions.

                (i)     If Bank at any time shall determine that for any reason
adequate and reasonable means do not exist for ascertaining LIBOR, then Bank
shall promptly give notice thereof to Borrower. If such notice is given and
until such notice has been withdrawn by Bank, then (A) no new LIBOR option may
be selected by Borrower, and (B) any portion of the outstanding principal
balance hereof which bears interest determined in relation to LIBOR, subsequent
to the end of the Fixed Rate Term applicable thereto, shall bear interest
determined in relation to the Prime Rate.

                (ii)    If any law, treaty, rule, regulation or determination of
a court or governmental authority or any change therein or in the interpretation
or application thereof (each a "Change in Law") shall make it unlawful for Bank
(A) to make LIBOR options available hereunder, or (B) to maintain interest rates
based on LIBOR, then in the former event, any obligation of Bank to make
available such unlawful LIBOR options shall immediately be cancelled, and in the
latter event, any such unlawful LIBOR-based interest rates then outstanding
shall be converted, at Bank's option, so that interest on the portion of the
outstanding principal balance subject thereto is determined in relation to the
Prime Rate; provided however, that if any such Change in Law shall permit any
LIBOR-based interest rates to remain in effect until the expiration of the Fixed
Rate Term applicable thereto, then such permitted LIBOR-based interest rates
shall continue in effect until the expiration of such Fixed Rate Term. Upon the
occurrence of any of the foregoing events, Borrower shall pay to Bank
immediately upon demand such amounts as may be necessary to compensate Bank for
any fines, fees, charges, penalties or other costs incurred or payable by Bank
as a result thereof and which are attributable to any LIBOR options made
available to Borrower hereunder, and any reasonable allocation made by Bank
among its operations shall be conclusive and binding upon Borrower.

                (iii)   If any Change in Law or compliance by Bank with any
request or directive (whether or not having the force of law) from any central
bank or other governmental authority shall:

                (A)     subject Bank to any tax, duty or other charge with
                        respect to any LIBOR options, or change the basis of
                        taxation of payments to Bank of principal, interest,
                        fees or any other amount payable hereunder (except for
                        changes in the rate of tax on the overall net income of
                        Bank); or

                (B)     impose, modify or hold applicable any reserve, special
                        deposit, compulsory loan or similar requirement against
                        assets held by, deposits or other liabilities in or for
                        the account of, advances or loans by, or any other
                        acquisition of funds by any office of Bank; or

                (C)     impose on Bank any other condition;

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing or maintaining any LIBOR options hereunder and/or to reduce any
amount receivable by Bank in connection therewith, then in any such case,
Borrower shall pay to Bank immediately upon demand such amounts as may be
necessary to compensate Bank for additional costs incurred by Bank and/or
reductions in amounts received by Bank which are attributable to such LIBOR
options. In determining which costs incurred by Bank and/or reductions in
amounts received by Bank are attributable to any LIBOR options made available to
Borrower hereunder, any reasonable allocation made by Bank among its operations
shall be conclusive and binding upon Borrower.

        (d)     Payment of Interest.  Interest accrued on this Note shall be
payable on the 1st day of each month, commencing May 1, 1997.

        (e)     Default Interest.  From and after the maturity date of this
Note, or such earlier date as all principal owing hereunder becomes due and
payable by acceleration or otherwise, the outstanding principal balance of this
Note shall bear interest until paid in full at an increased rate per annum
(computed on the basis of a 360-day year, actual days elapsed) equal to 4%
above the rate of interest from time to time applicable to this Note.

BORROWING AND REPAYMENT:

        (a)     Borrowing and Repayment.  Borrower may from time to time during
the term of this Note borrow, partially or wholly repay its outstanding
borrowings, and reborrow, subject to all of the limitations, terms and
conditions of this Note and of any document executed in connection with or
governing this Note; provided however, that the total outstanding borrowings
under this Note shall not at any time exceed the principal amount stated above.
The unpaid principal balance of this obligation at any time shall be the total
amounts advanced hereunder by the holder hereof less the amount of principal
payments made hereon by or for any Borrower, which balance may be endorsed
hereon


Revolving Line of Credit Note (08/96), Page 2
   21
from time to time by the holder. The outstanding principal balance of this Note
shall be due and payable in full on May 1, 1998.

        (b)  Advances.  Advances hereunder, to the total amount of the principal
sum available hereunder, may be made by the holder at the oral or written
request of (i) Ruth Updegruff, Charley Eddly, Kevin Soulsby, Norman Pond, any
one acting alone, who are authorized to request advances and direct the
disposition of any advances until written notice of the revocation of such
authority is received by the holder at the office designated above, or (ii) any
person, with respect to advances deposited to the credit of any account of any
Borrower with the holder, which advances, when so deposited, shall be
conclusively presumed to have been made to or for the benefit of each Borrower
regardless of the fact that persons other than those authorized to request
advances may have authority to draw against such account. The holder shall have
no obligation to determine whether any person requesting an advance is or has
been authorized by any Borrower.

        (c)  Application of Payments.  Each payment made on this Note shall be
credited first, to any interest then due and second, to the outstanding
principal balance hereof. All payments credited to principal shall be applied
first, to the outstanding principal balance of this Note which bears interest
determined in relation to the Prime Rate, if any, and second, to the
outstanding principal balance of this Note which bears interest determined in
relation to LIBOR, with such payments applied to the oldest Fixed Rate Term
first.

PREPAYMENT:

        (a)  Prime Rate.  Borrower may prepay principal on any portion of this
Note which bears interest determined in relation to the Prime Rate at any time,
in any amount and without penalty.

        (b)  LIBOR.  Borrower may prepay principal on any portion of this Note
which bears interest determined in relation to LIBOR at any time and in the
minimum amount of $10,000.00; provided however, that if the outstanding
principal balance of such portion of this Note is less than said amount, the
minimum prepayment amount shall be the entire outstanding principal balance
thereof. In consideration of Bank providing this prepayment option to Borrower,
or if any such portion of this Note shall become due and payable at any time
prior to the last day of the Fixed Rate Term applicable thereto by acceleration
or otherwise. Borrower shall pay to Bank immediately upon demand a fee which is
the sum of the discounted monthly differences for each month from the month of
prepayment through the month in which such Fixed Rate Term matures, calculated
as follows for each such month:

        (i)  Determine the amount of interest which would have accrued each
month on the amount prepaid at the interest rate applicable to such amount had
it remained outstanding until the last day of the Fixed Rate Term applicable
thereto.

        (ii)  Subtract from the amount determined in (i) above the amount of
interest which would have accrued for the same month on the amount prepaid for
the remaining term of such Fixed Rate Term at LIBOR in effect on the date of
prepayment for new loans made for such term and in a principal amount equal to
the amount prepaid.

        (iii)  If the result obtained in (ii) for any month is greater than
zero, discount that difference by LIBOR used in (ii) above.

Each Borrower acknowledges that prepayment of such amount may result in Bank
incurring additional costs, expenses and/or liabilities, and that it is
difficult to ascertain the full extent of such costs, expenses and/or
liabilities. Each Borrower, therefore, agrees to pay the above-described
prepayment fee and agrees that said amount represents a reasonable estimate of
the prepayment costs, expenses and/or liabilities of Bank. If Borrower fails to
pay any prepayment fee when due, the amount of such prepayment fee shall
thereafter bear interest until paid at a rate per annum 2.000% above the Prime
Rate in effect from time to time (computed on the basis of a 360-day year,
actual days elapsed). Each change in the rate of interest on any such past due
prepayment fee shall become effective on the date each Prime Rate change is
announced within Bank.

EVENTS OF DEFAULT:

        The occurrence of any of the following shall constitute an "Event of
Default" under this Note:

        (a)  The failure to pay any principal, interest, fees or other charges
