Gentlemen:

      This letter is to confirm the changes agreed upon between Wells Fargo
Bank, National Association ("Bank") and Intevac, Inc. ("Borrower") to the terms

acknowledged, Bank and Borrower hereby agree that the Agreement shall be
amended as follows to reflect said changes.

      1.  The Agreement is hereby amended by deleting "May 1, 1998" as the last
day on which Bank will make advances under the Line of Credit, and by
substituting for said date "May 1, 1999," with such change to be effective upon
the execution and delivery to Bank of a promissory note substantially in the
form of Exhibit A attached hereto (which promissory note shall replace and be
deemed the Line of Credit Note defined in and made pursuant to the Agreement)
and all other contracts, instruments and documents required by Bank to evidence
such change.

      2.  Paragraphs V.3.(c) and (d) are hereby deleted in their entirety,
without substitution.

      3.  Paragraph V.3.(e) shall be renumbered to Paragraph V.3.(c).

      4.  Paragraph V.8.(a) is hereby deleted in its entirety, and the
following substituted therefor:

            "(a)  Tangible Net Worth not at any time less than $90,000,000.00,
      with "Tangible Net Worth" defined as the sum of the capital stock and
      additional paid in capital, plus retained earnings, plus subordinated debt
      of the Borrower and its subsidiaries, minus intangible assets on a
      consolidated basis and minus any permitted stock repurchase."

      5.  The following is hereby added to the Agreement as Paragraph V.15.:

            "15.  Year 2000 Compliance.  Perform all acts reasonably necessary
      to ensure that (a) Borrower and any business in which Borrower holds a
      substantial interest, and (b) all customers, suppliers and vendors that
      are material to Borrower's business, become Year 2000 Compliant in a
      timely manner. Such acts shall include, without limitation, performing a
      comprehensive review and assessment of all of Borrower's systems and
      adopting a detailed plan, with itemized budget, for the remediation,
      monitoring and testing of such systems. As used herein, "Year 2000
      Compliant" shall mean, in regard to any entity, that all software,
      hardware, firmware, equipment, goods or systems utilized by or material to
      the business operations or financial condition of such entity, will
      properly perform date sensitive functions before, during and after the
      year 2000. Borrower shall, immediately upon request, provide to Bank such
      certifications or other evidence of Borrower's compliance with the terms
      hereof as Bank may from time to time require."

      6.  Except as specifically provided herein, all terms and conditions of
the Agreement remain in full force and effect, without waiver or modification.
All terms defined in the Agreement shall have the same meaning when used
herein. This letter and the Agreement shall be read together, as one document.

      7.  Borrower hereby remakes all representations and warranties contained
in the Agreement and reaffirms all covenants set forth therein. Borrower
further certifies that as of the date of Borrower's acknowledgement set forth
below there exists no default or defined event of default under the Agreement
or any promissory note or other contract, instrument or document executed in
connection therewith, nor any condition, act or event which with the giving of
notice or the passage of time or both would constitute such a default or
defined event of default.

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

$10,000,000.00                                              San Jose, California
                                                                     May 1, 1998

     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
98115, 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, then
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 1.78000%
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 not 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 a 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 (02/98), Page 1

   5
principal amount subject thereto, and (iii) 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 change with respect to
any LIBOR options, or change the basis of taxation of payments to Bank of
principal, interests, 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 any 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 June 1, 1998.

      (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 (02/98), Page 2

     









   6
from time to time by the holder. The outstanding principal balance of this Note
shall be due and payable in full on May 1, 1999.

     (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 UPDAGRAFF or CHARLES EDDY or KEVIN SOULSBY or 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 $10,000.000; 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
when due hereunder or under any contract, instrument or document executed in
connection with this Note.

     (b)  The filing of a petition by or against any Borrower, any guarantor of
this Note or any general partner or joint venturer in any Borrower which is a
partnership or a joint venture (with each such guarantor, general partner
and/or joint venturer referred to herein as a "Third Party Obligor") under any
provisions of the Bankruptcy Reform Act, Title 11 of the United States Code, as
amended or recodified from time to time, or under any similar or other law
relating to bankruptcy, insolvency, reorganization or other relief for debtors;
the appointment of a receiver, trustee, custodian or liquidator of or for any
part of the assets or property of any Borrower or Third Party Obligor; any
Borrower or Third Party Obligor becomes insolvent, makes a general assignment
for the benefit of creditors or is generally not paying its debts as they
become due; or any attachment or like levy on any property of any Borrower or
Third Party Obligor.

     (c)  The death or incapacity of any individual Borrower or Third Party
Obligor, or the dissolution or liquidation of any Borrower or Third Party
Obligor which is a corporation, partnership, joint venture or other type of
entity.






Revolving Line of Credit Note (02/98), Page 3

   7
     (d)  Any default in the payment or performance of any obligation, or any
defined event of default, under any provisions of any contract, instrument or
document pursuant to which any Borrower or Third Party Obligor has incurred any
obligation for borrowed money, any purchase obligation, or any other liability
of any kind to any person or entity, including the holder.

     (e)  Any financial statement provided by any Borrower or Third Party
Obligor to Bank proves to be incorrect, false or misleading in any material
respect.

     (f)  Any sale or transfer of all or a substantial or material part of the
assets of any Borrower or Third Party Obligor other than in the ordinary course
of its business.

     (g)  Any violation or breach of any provision of, or any defined event of
default under, any addendum to this Note or any loan agreement, guaranty,
security agreement, deed of trust, mortgage or other document executed in
connection with or securing this Note.

MISCELLANEOUS:

     (a)  Remedies. Upon the occurrence of any Event of Default, the holder of
this Note, at the holder's option, may declare all sums of principal and
interest outstanding hereunder to be immediately due and payable without
presentment, demand, notice of nonperformance, notice of protect, protest or
notice of dishonor, all of which are expressly waived by each Borrower, and the
obligation, if any, of the holder to extend any further credit hereunder shall
immediately cease and terminate. Each Borrower shall pay to the holder
immediately upon demand the full amount of all payments, advances, charges,
costs and expenses, including reasonable attorneys' fees (to include outside
counsel fees and all allocated costs of the holder's in-house counsel),
expended or incurred by the holder in connection with the enforcement of the
holder's rights and/or the collection of any amounts which become due to the
holder under this Note, and the prosecution or defense of any action in any way
related to this Note, including without limitation, any action for declaratory
relief, whether incurred at the trial or appellate level, in an arbitration
proceeding or otherwise, and including any of the foregoing incurred in
connection with any bankruptcy proceeding (including without limitation, any
adversary proceeding, contested matter or motion brought by Bank or any other
person) relating to any Borrower or any other person or entity.

     (b)  Obligations Joint and Several. Should more than one person or entity
sign this Note as a Borrower, the obligations of each such Borrower shall be
joint and several.

     (c)  Governing Law. This Note shall be governed by and construed in
accordance with the laws of the state of California.

     IN WITNESS WHEREOF, the undersigned has executed this Note as of the date
first written above.
