Preliminary Copy                                                   June 14, 1996

To Our Shareholders:

         I cordially invite you to attend the special meeting of Giga-tronics
Incorporated ("Giga-tronics") shareholders to be held at 10:00 a.m. on
Wednesday, July 17, 1996, at the Giga-tronics facility, 4650 Norris Canyon Road,
San Ramon, California.

         At such meeting, Giga-tronics shareholders will be asked to consider
and approve the issuance of 724,986 shares of Giga-tronics Common Stock in
connection with the proposed Merger of Giga-tronics and ASCOR, Inc. ("ASCOR"),
as described in the attached Joint Proxy Statement/Prospectus. As a result of
the "Merger," and subject to the approval of the Merger by the shareholders of
ASCOR, a newly created wholly owned subsidiary of Giga-tronics would be merged
into ASCOR, whereby ASCOR would become a wholly owned subsidiary of Giga-tronics
and continue operating as a separate company, and each ASCOR shareholder would
receive Giga-tronics common stock as consideration for his or her ASCOR stock.
The Merger Agreement provides that each share of ASCOR stock and other
securities convertible into ASCOR stock would be converted into the right to
receive the quotient of (i) 724,986 shares of Giga-tronics common stock, divided
by (ii) the total number of ASCOR shares and such convertible securities
outstanding at the time the Merger shall become effective. Cash will be paid in 
lieu of issuance of any fractional shares. If the merger is consummated, the
percentage of outstanding stock of Giga-tronics held by ASCOR shareholders would
be approximately 21.5%.
    

         Your Board of Directors has determined, after due deliberation and
discussion, that the consideration to be given to the ASCOR shareholders in the
Merger is fair from a financial point of view to, and in the best interests of,
Giga-tronics and the shareholders of Giga-tronics. The Board of Directors, by
unanimous vote, has approved the terms of the Merger Agreement, and recommends
that Giga-tronics shareholders vote FOR the proposed Merger and the issuance of
724,986 shares of Giga-tronics Common Stock in connection with the proposed
Merger. It should be noted that two of the four members of the Giga-tronics
Board of Directors also participate on the ASCOR Board of Directors.
Additionally, three of the four members of the Giga-tronics Board hold varying
amounts of ASCOR stock and stock equivalents. Each shareholder is urged to read
the attached Joint Proxy Statement/Prospectus accompanying this letter for more
details.

         Approval of the Merger and issuance of Giga-tronics Common Stock
requires the approval of a majority of the outstanding shares held by
Giga-tronics shareholders. For more details with respect to all of the
foregoing, each shareholder is urged to read the Joint Proxy
Statement/Prospectus accompanying this letter.

         The Company counts on your continued interest, and I hope you will be
able to attend the meeting. However, regardless of whether you plan to attend in
person, it is important that your vote be counted. I urge you to vote your
shares by signing and returning the accompanying proxy card.

                                       Sincerely,

                                       George H. Bruns, Jr.

Risk Factors

         Giga-tronics. The issuance of Giga-tronics Common Stock to ASCOR
shareholders and consummation of the Merger involves a degree of risk. In
addition to other information included elsewhere in this Joint Proxy
Statement/Prospectus, holders of Giga-tronics Common Stock should consider the
following: (i) dependence on key ASCOR personnel, (ii) potential distribution
channel risks and dropping of Giga-tronics products by "sales reps," (iii) the
reliance of ASCOR's revenue stream on a single family of products, (iv) ASCOR's
reliance on major defense contracts and a relatively small number of customers,
(v) facility and personnel issues related to ASCOR sales growth, and (vi)
potential effects on the Giga-tronics stock price of ASCOR's large shareholders
wishing to become liquid over a short time period. Before voting on the Merger,
shareholders of Giga-tronics should carefully consider the information set forth
in "Risk Factors - Giga-tronics," beginning on page 17, as well as other
information in the entire Proxy.

         ASCOR. The Merger of ASCOR into Giga-tronics involves a degree of risk
for ASCOR shareholders. In addition to other information included elsewhere in

The Special Meeting and Votes Required

   
          The Special Meeting of Giga-tronics Shareholders will be held at 10:00
a.m. on July 17, 1996, at the Giga-tronics facilities at 4650 Norris Canyon
Road, San Ramon, California 94583. The holders of record of Giga-tronics Common
Stock as of the close of business on June 14, 1996, will be entitled to notice
of and to vote at the Special Meeting. At this Special Meeting Giga-tronics'
shareholders will be asked to vote upon a proposal to approve the Merger to be
effected pursuant to the Reorganization Agreement. Approval of the Merger
requires the affirmative vote of at least a majority of the outstanding shares
of Common Stock held by Giga-tronics shareholders. At the close of business on
June 14, 1996, directors and officers of Giga-tronics and their affiliates, in
the aggregate were entitled to vote 438,538 shares of Giga-tronics Common Stock,
representing 16.5% of the total shares entitled to vote at the Special Meeting.

          ASCOR will be soliciting the approval of its shareholders by delivery
of this Joint Proxy Statement/Prospectus with a request that the shareholders
entitled to vote with respect to approval of the Merger give their written
consent to the Merger. Approval of the Merger by ASCOR's shareholders requires
the written consent of persons holding a majority of the votes entitled to be
cast by holders of outstanding (a) ASCOR Common Stock voting as a class, (b)
ASCOR Preferred Stock voting as a separate class and (c) ASCOR Common Stock and
ASCOR Preferred Stock voting together as a single class. Each share of ASCOR
Common Stock is entitled to one vote and each share of ASCOR Preferred Stock is
entitled to such number of votes as the number of shares of ASCOR Common Stock
into which such share of ASCOR Preferred Stock is convertible, At the close of
business on June 14, 1996, directors and officers of ASCOR and their affiliates,
in the aggregate held approximately 5,741,368 shares of ASCOR Common Stock and
shares of ASCOR Preferred Stock entitled to cast approximately 4,164,023 votes,
representing approximately 73% of the outstanding shares of ASCOR Common Stock,
approximately 78% of the total votes entitled to be voted by ASCOR Preferred
Stock and approximately 75% of the total votes entitled to be voted by ASCOR
Common Stock and ASCOR Preferred Stock voting together as a single class, by
written consent with respect to the Merger.
    

Description of the Merger

         At the effective time of the Merger (the "Effective Time"), (i)
Acquisition Corp. will be merged with and into ASCOR and ASCOR will become a
wholly owned subsidiary of Giga-tronics; (ii) each (a) share of ASCOR no par
value Common Stock ("ASCOR Common Stock") and no par value preferred stock
("ASCOR Preferred Stock" and, together with ASCOR Common Stock, the "ASCOR
Shares") outstanding immediately prior to the Merger (other than ASCOR Shares
held by shareholders who have perfected and not withdrawn their right to seek
appraisal of their shares under applicable California law) and (b) outstanding
options for the purchase of ASCOR Shares ("ASCOR Option") and warrants
exercisable for the purchase of ASCOR Shares ("ASCOR Warrant" and, together with
any ASCOR Options, the "ASCOR Convertible Securities") will be converted into
the right to receive a pro rata portion of an aggregate of 724,986 Shares of
Giga-tronics Common Stock to be issued in the Merger (the "Merger
Consideration"). In determining the fraction of a Giga-tronics Stock (the
"Exchange Ratio") which holders of ASCOR Shares and ASCOR Convertible Securities
(collectively "ASCOR Securities") will be entitled to receive, all ASCOR
Convertible Securities will be treated as having been converted or exercised
into ASCOR Shares. Any ASCOR Convertible Securities which are considered
"out-of-the-money" will be assumed by Giga-tronics and will be exercisable for
Giga-tronics Common Stock as adjusted by the Merger. Shares of Giga-tronics
Common Stock attributable to ASCOR Convertible Securities which are assumed by
Giga-tronics will be retained by Giga-tronics from the Merger Consideration
pending their exercise. See "THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS
- - The Exchange Ratio and ASCOR Convertible Securities." See "THE MERGER -
Description of the Merger" and "Dissenter's Appraisal Rights."

                                      -9-
<PAGE>   17
         A maximum of 724,986 shares of Giga-tronics Common Stock will be
issuable in the Merger, including (a) shares issuable in respect of ASCOR
Convertible Securities which are assumed, which shares will be retained by
Giga-tronics if such securities expire unexercised, (b) fractional shares, (c)
shares issuable in respect of ASCOR Shares for which dissenters' appraisal
rights (see "THE MERGER - Dissenters' Appraisal Rights") are perfected, and (d)
shares deemed surrendered upon exercise of ASCOR Convertible Securities for
which a deemed net exercise has occurred. The Merger will be effective at the
time an Agreement of Merger is filed with the Secretary of State of the State of
California. Assuming all conditions to the Merger are met or waived prior
thereto, it is anticipated that the Effective Time will occur not later than
June 28, 1996. See "THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS - The
Reorganization Agreement - The Exchange Ratio."

Other Matters Related to the Merger

         Background of the Merger: The terms of the Merger (including the Merger
Consideration) were determined through negotiations between Giga-tronics and
ASCOR. For a description of these negotiations, see "THE MERGER - Background of
the Merger."

         Giga-tronics' Reasons for the Merger; Recommendations of the
Giga-tronics Board: The Board of Directors of Giga-tronics believes that the
issuance of Common Stock in connection with the Merger of Giga-tronics and ASCOR
is fair to and in the best interests of Giga-tronics and its shareholders. The
proposed Reorganization Agreement has been approved by the Board by unanimous
vote, noting that two of the four Board members are also members of the ASCOR
Board of Directors. Additionally, three of the four Giga-tronics Board members
hold varying amounts of ASCOR Shares and ASCOR Convertible Securities. In
evaluating the Merger, the Board considered the following factors as important:
(i) ASCOR's business prospects and recent results of operations and financial
position, (ii) the benefit of having access to certain of ASCOR's technology and
technical resources, (iii) the potential synergistic benefits derived from the
coordination of sales and marketing strategies, and (iv) the ease of integration
and exchange of ideas due to long-term familiarity. The Giga-tronics Board of
Directors, in making its recommendation to shareholders, considered the positive
and negative factors as a whole.

         THE BOARD OF DIRECTORS OF GIGA-TRONICS UNANIMOUSLY RECOMMENDS THAT
GIGA-TRONICS SHAREHOLDERS VOTE FOR APPROVAL OF THE PROPOSAL REGARDING THE MERGER
TO BE EFFECTED PURSUANT TO THE REORGANIZATION AGREEMENT.

         ASCOR's Reasons; Recommendations of the ASCOR Board: The Board of
Directors of ASCOR believes that terms of the Reorganization Agreement is fair
to and in the best interest of ASCOR and its shareholders. The Reorganization
Agreement has been approved by the Board of Directors of ASCOR by unanimous
vote, noting that two of the five members of the ASCOR Board of Directors are
also members of the Giga-tronics Board. Additionally, two of the members of the
ASCOR Board of Directors hold varying amounts of Giga-tronics stock and stock
equivalents. In evaluating the Reorganization Agreement, the Board considered
the following important factors: (i) Giga-tronics' business prospects and recent
results of operations and financial position, (ii) the benefit of having access
to certain of Giga-tronics' sales and marketing resources, (iii) the ease of
integration and exchange of ideas due to long-term familiarity between the
companies, (iv) the benefit of having access to certain management resources to
help sustain ASCOR's possible sales growth, and (v) increased liquidity for
holders of ASCOR stock and stock equivalents. The ASCOR Board of Directors, in
making its recommendation to shareholders, considered the positive and negative
factors as a whole. THE BOARD OF DIRECTORS OF ASCOR RECOMMENDS THAT ASCOR
SHAREHOLDERS VOTE FOR APPROVAL OF THE PROPOSAL REGARDING THE MERGER TO BE
EFFECTED PURSUANT TO THE REORGANIZATION AGREEMENT.

                                      -10-
<PAGE>   18
         Opinion of Giga-tronics Financial Advisor: Wood, Warren & Co. has
rendered to the Board of Directors of Giga-tronics its written opinion dated as
of May 2, 1996 that, as of such date and based upon and subject to the matters
set forth therein the Exchange Ratio to be applied in the Merger is fair, from a
financial point of view, to Giga-tronics. See "Giga-tronics Financial Advisor's
Opinion." Giga-tronics' Shareholders are urged to read this opinion carefully in
its entirety for assumptions made, matters considered and the limits of the
review undertaken by Wood, Warren & Co.

   
         Conflicts of Interest: Mr. George H. Bruns, Jr. is Chairman of the
Board of Directors of both Giga-tronics and ASCOR. Two of the four Giga-tronics
Directors (including Mr. Bruns) participate on the Board of Directors of ASCOR.
Likewise, two of the five ASCOR Directors (including Mr. Bruns) participate on
the Giga-tronics Board. Additionally, Mr. George H. Bruns, Jr. is the Chief
Executive Officer of Giga-tronics. It also should be noted that three of the
four Giga-tronics Board members (which includes Mr. George H. Bruns, Jr., the
Giga-tronics Chief Executive Officer and Chairman of both Boards) beneficially
own shares of ASCOR Common or Preferred Stock or ASCOR warrants. These three
members hold approximately 33% of the ASCOR outstanding stock and approximately
17% of the Giga-tronics Common Stock as of the record date of June 14, 1996.
Additionally, since the ASCOR warrants may be converted into shares of
Giga-tronics Common Stock in connection with the Merger, these three members may
hold approximately 20% of the combined Company Common Stock if the Merger is
consummated.
    

         Conditions to Merger; Termination and Expenses: Consummation of the
Merger is subject to the satisfaction of various conditions, including among
other things approval of the Merger Agreement by Giga-tronics shareholders and
by ASCOR shareholders, the absence of any material adverse change in the
business or financial condition of Giga-tronics or ASCOR, the ability of
Giga-tronics to account for the Merger as a pooling of interests, the absence of
the perfection of dissenters' appraisal rights by Giga-tronics Shareholders with
respect to 5% or more of the Giga-tronics Common Stock Outstanding on the date
of the Special Meeting and the requirement that all outstanding ASCOR Preferred
Stock be tendered for exchange into Giga-tronics Common Stock at the Closing in
accordance with the provisions of tender instructions (the "Tender
Instructions") which will stipulate such ASCOR Preferred Stock tendered
therewith be exchanged for Giga-tronics Common Stock in accordance with the
terms of the Reorganization Agreement, notwithstanding any other rights the
ASCOR Preferred Stock may have or which might arise in a transaction such as the
Merger. See 'DESCRIPTION OF GIGA-TRONICS AND ASCOR SECURITIES - ASCOR - ASCOR
Preferred Stock" and "THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS - The
Reorganization Agreement - Conditions to the Merger." Except as to any condition
the satisfaction of which is required by law, the Boards of Directors of ASCOR
and Giga-tronics have the authority to waive satisfaction of the respective
conditions to such Company's obligations to consummate the Merger. See "THE
REORGANIZATION AGREEMENT AND RELATED AGREEMENTS - The Reorganization Agreement
Conditions to the Merger". The Reorganization Agreement may be terminated at any
time prior to consummation of the Merger by mutual consent of the Boards of
Directors of Giga-tronics and ASCOR and by the Board of Directors of
Giga-tronics in certain circumstances. The Reorganization Agreement may be
amended by mutual consent of the Boards of Directors of Giga-tronics and ASCOR
at any time, except that, after approval of the Merger by Giga-tronics and ASCOR
shareholder, respectively, no amendment that would have a material adverse
effect on such shareholders will be made without obtaining the further approval
of said shareholders. See "THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS -
The Reorganization Agreement - Termination."

         Summary of Income Tax Consequences: It is a condition to the Merger
that Giga-tronics and ASCOR receive tax opinions to the effect that the Merger
will constitute a tax-free reorganization for federal income tax purposes. The
Merger has been structured with the intent that

                                      -11-
<PAGE>   19
ASCOR shareholders will recognize no gain or loss on the exchange of ASCOR
Common Stock into Giga-tronics Common Stock, except for gain or loss
attributable to cash received in lieu of fractional shares. ASCOR shareholders
are advised to consult their own tax advisors regarding all tax consequences of
the Merger. See "THE MERGER - Certain Federal Income Tax Consequences."

         Accounting Treatment: The Merger is intended to qualify as a
pooling-of-interests for accounting and financial reporting purposes. Under this
method of accounting, the assets and liabilities of Giga-tronics and ASCOR will
be carried forward to the combined company at their recorded historical amounts,
income of the combined company will include income of Giga-tronics and ASCOR for
the entire fiscal period in which the combination occurs and the reported income
of the separate companies for prior periods will be combined and restated as
income of the combined company. See "THE MERGER - Accounting Treatment."

         Management of Giga-tronics and ASCOR Following the Merger: ASCOR will
be a wholly owned subsidiary of Giga-tronics after the Merger. The Board of
Directors of the combined Giga-tronics Company after the Merger will be the same
as the current Giga-tronics Board. The current President of ASCOR, Mr. Jeffrey
Lum, will report to Mr. George Bruns, Jr., Chief Executive Officer of
Giga-tronics, after the Merger. Mr. Lum will be an officer of Giga-tronics, as
well as remain President of the ASCOR subsidiary. The other four remaining
Giga-tronics officers (including Mr. George Bruns, Jr. as Chief Executive
Officer) will remain the same after the Merger. The four officers of ASCOR
currently (including Mr. Jeffrey Lum) will remain officers of the ASCOR
subsidiary after the Merger.

         Dissenters' Rights: Under the California General Corporation Law (the
"California Corporate Law") ASCOR Shareholders will be entitled to dissenters'
rights of appraisal in connection with the Merger. Giga-tronics Shareholders
will also be entitled to such rights under certain circumstances. (See "THE
MERGER - Appraisal Rights.") In the event that shareholders of Giga-tronics
exercise their rights to dissent with respect to 5% or more of the outstanding
shares of Giga-tronics Common Stock, or if holders of ASCOR Shares exercise
dissenters' rights with respect to such number of shares of ASCOR stock such
that the Merger cannot be accounted for as a pooling of interests, the Board of
Directors of Giga-tronics may elect not to proceed with implementation of the
Merger, notwithstanding the approval of the Merger by ASCOR's and Giga-tronics'
shareholders. See "THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS - The
Reorganization Agreement - Conditions to the Merger."

         Comparison of Shareholders' Rights: There are no material differences
between the rights of holders of ASCOR Common Stock and the rights of holder of
Giga-tronics Common Stock, as both corporations are organized in the State of
California and have similar Articles of Incorporation and By-Laws. See
"COMPARISON OF RIGHTS OF SHAREHOLDERS OF GIGA-TRONICS and ASCOR AND DESCRIPTION
OF GIGA-TRONICS AND ASCOR SECURITIES."

         Exchange Procedures: Promptly after the consummation of the Merger,
Chemical Mellon Shareholder Services of California (the "Exchange Agent") will
mail a letter of transmittal with instructions to all holders of record of ASCOR
Securities as of the Effective Time of the Merger regarding the exchange of
their ASCOR share certificates for certificates representing shares of
Giga-tronics Common Stock. ASCOR Shareholders should not surrender any
Certificates until the letter of transmittal is received. A holder of ASCOR
Securities will not be entitled to any rights of a holder of Giga-tronics Common
Stock until such holder exchanges the ASCOR Securities for certificates
representing Giga-tronics Common Stock. See "THE REORGANIZATION AGREEMENT AND
RELATED AGREEMENTS - The Reorganization Agreement - Exchange of Certificates"
for more details.

Certain Related Agreements:

         Letter Agreement. Pursuant to a letter agreement among Giga-tronics and
ASCOR dated May 20, 1996 (the "Letter Agreement"), Giga-tronics has agreed to
use its best faith efforts to effect the registration pursuant to federal
securities laws of the Giga-tronic Common Stock to be issued in the Merger on a
Form S-4 registration statement. See "THE REORGANIZATION AGREEMENT AND RELATED
AGREEMENTS - Letter Agreement."

         Registration Rights Agreement. The Reorganization Agreement
contemplates that the Giga-tronics Common Stock to be issued in the Merger would
not be issued pursuant to a registration statement under federal securities law,
but rather pursuant to exemption from such registration requirements as a
private placement. If Giga-tronics is unable to effect the registration of such
Giga-tronics Common Stock as contemplated by the Letter Agreement, at the
Effective Time Giga-tronics will enter into a Registration Rights Agreement with
holders of ASCOR Securities who receive Giga--tronics Common Stock pursuant to
which they will be granted certain demand and piggyback registration rights with
respect to such Giga-tronics Common Stock. See "THE REORGANIZATION AGREEMENT AND
RELATED AGREEMENTS - The Reorganization Agreement - Registration of Merger
Consideration and The Registration Rights Agreement."

Summary Historical and Pro Forma Financial Information:

         The following historical financial information of Giga-tronics and
ASCOR has been derived from their respective historical consolidated financial
statements, and should be read in conjunction with such consolidated financial
statements and the notes thereto, which are included as Annexes to this Joint
Proxy Statement/Prospectus. The selected pro forma financial information of
Giga-tronics and ASCOR is derived from the unaudited pro forma combined
condensed financial statements and should be read in conjunction with such pro
forma statements and notes thereto, which are included elsewhere in this Joint
Proxy Statement/Prospectus. For pro forma purposes, ASCOR financial data covers
the approximate comparable financial reporting periods used by Giga-tronics.

         The pro forma financial information does not purport to represent what
Giga-tronics' financial position or results of operations would actually have
been had the Merger occurred at the beginning of the earliest period presented
or to project Giga-tronics' financial position or results of operations for any
future date or period.

   
         Neither Giga-tronics or ASCOR has declared or paid any dividends on its
capital stock during the periods presented.

Comparative Per Share Data:

   
         Set out below are income and book value per common share data of
Giga-tronics and ASCOR on both a historical and unaudited pro forma condensed
combined basis and on a per share equivalent unaudited pro forma basis for
ASCOR. Unaudited pro forma condensed combined per share information is derived
from the unaudited pro forma condensed combined information presented elsewhere
herein which gives effect to the Merger under the pooling of interests
accounting method at the beginning of the earliest period presented, and assumes
the issuance of 724,986 shares of Giga-tronics Common Stock in 1995 and 1994.
Expenses directly attributable to the consummation of the Merger are expected to
approximate $250,000. The pro forma adjustment to retained earnings is
$125,000 while the total estimated costs are $250,000 because $125,000 of costs
are already included in the fiscal 1996 financial statements. The estimated
$250,000 of merger costs are not included in the pro forma statements of
operations since they will be nonrecurring. The expenses have been deducted in
calculating the pro forma combined book value per share, but are not reflected
in the pro forma earnings (loss) per share amounts. Neither Giga-tronics or
ASCOR has declared or paid any dividends on its capital stock during the periods
presented.
    

         The pro forma information is presented for illustrative purposes only
and is not necessarily indicative of the operating results or financial position
that would have occurred if the Merger had been consummated, nor is it
necessarily indicative of future operating results or financial position.

                                  RISK FACTORS
   
     GIGA-TRONICS

     In addition to the other information included in this Joint Proxy
Statement/Prospectus, the following information should be considered carefully
by holders of Giga-tronics Common Stock in evaluating the Merger.

Dependence On Key Personnel and Ability to Hire Technical Staff to 
Support Growth
    

     ASCOR's future success is highly dependent on certain key management and
technical personnel. The loss of any one of these key personnel could have a
material adverse impact on ASCOR's results of operation. In addition, there will
be no employment contracts awarded to any of these personnel during the Merger.
Stock options in the combined Company may be granted in the normal course of
business, and the key personnel will have a significant equity interest in the
combined Company. ASCOR has "key-executive" life insurance for Mr. Jeffrey Lum,
President of ASCOR. See "THE MERGER - Management and Security Ownership After
the Merger."

     ASCOR employs technical staff with a need for a precise set of engineering
skills. Given the short supply and high demand on engineers in general since
1994 (due to business expansion in Silicon Valley), rapid growth could put a
strain on the Company's ability to hire technical personnel at a pace fast
enough to support the higher sales volume.

Distribution Channel Conflicts

     Some of the sales representatives which currently sell Giga-tronics
products also sell the Racal Dana VXI product line which competes with ASCOR's
products. Since historically, Racal Dana has generated significantly more volume
than ASCOR, and since some representatives may have a conflict of interest with
Racal Dana by carrying ASCOR products as well as Giga-tronics (post-Merger)
products, many of such sales representatives may have to be convinced that it is
in their best interest to also represent ASCOR products and to continue to
represent Giga-tronics products. There are eight major Giga-tronics sales
representatives which also market Racal Dana products. These representatives
currently sell approximately $13 million of Giga-tronics products annually.
Giga-tronics may be required to develop new sales representatives should current
ones resign. There can be no assurance that any loss of sales of Giga-tronics
products due to the loss of such sales representatives will be offset by sales
of ASCOR products or that Giga-tronics would be successful in developing
additional sales representatives to replace any lost sales due to the
above-described conflicts.

   
Reliance on A Single Family of Products That Are Military-Dependent

     All of ASCOR's revenues are associated with the VXI architecture. The
future expansion of the Company is dependent on increased acceptance of this
type of architecture by customers. To date, acceptance has been primarily by the
military, and military orders have generally been soft across most markets in
recent years. If military orders declined in the future and if ASCOR is unable
to gain acceptance by civilian customers, ASCOR's sales might suffer, which may
result in a material adverse effect on the combined companies.

<PAGE>   25
Reliance On Major Contracts and A Few Number of Customers

     ASCOR relies on a relatively small number of large government contracts and
government related orders comprise most of its sales. Though ASCOR's few
customers are large companies, they also are few in number. The contracts are
usually awarded following a competitive bidding process which can begin well
before the contract is awarded. The timing and likelihood of any particular
contract is difficult to predict. Revenue and earnings are therefore subject to
significant fluctuations between quarterly and annual periods depending on the
number of contracts awarded.

   
Management Of Growth and Potential Higher Overhead Cost of New Facility

     ASCOR currently is utilizing all of the available space in its leased
Fremont facility. In addition, the lease on the facility is due to expire on
January 31, 1998. If sales volume grows significantly over the next year or two,
a larger facility will need to be secured. Since current lease rates being paid
by ASCOR are substantially below market, a new larger facility at market rates
would add significantly to the Company's overhead costs. Higher overhead costs
would increase the sales volume break-even point and cause potential volume
fluctuations to have a bigger impact on profit. Given the small number of
contracts and customers in the current sales mix (See " - Reliance on Major
Contracts and A Few Number of Customers"), the Company's vulnerability would be
enhanced.

Future Sales of Giga-tronics Common Stock Issued in Merger Could Adversely
Impact Stock Price

     In the event that the ASCOR shareholders wish to sell all or a portion of
their Giga-tronics Common Stock after consummation of the Merger, their effort
to do so could result in a depression of the Giga-tronics share price traded on
NASDAQ due to the historically thin trading volume of Giga-tronics stock.

     ASCOR

     In addition to the foregoing risk factors which would affect them as
shareholders of Giga-tronics and the other information included in this Joint
Proxy Statement/Prospectus, the following information should also be considered
carefully by holders of ASCOR common stock and common stock equivalents in
evaluating the Merger.

Limited Liquidity for ASCOR Shareholders and Potential Adverse Impact on
Giga-tronics Stock Price

     Giga-tronics stock has historically traded on thin volume on NASDAQ. The
ASCOR shareholders receiving Giga-tronics stock may not be able to sell a
significant volume of stock if they wished to increase their liquidity after the
Merger. In addition, their effort to sell significant volume of their newly
acquired stock could result in a depression of the Giga-tronics share price. In
any circumstance, such shareholdings will certainly be subject to the vagaries
of the market place.

Giga-tronics Revenues Could Decrease Due to Declining Order Intake

     Current softness in the market for Giga-tronics products has resulted in a
substantial decline in backlog. If this trend cannot be reversed in the near
term, Giga-tronics shipments in the current year could fall short of plan with a
concurrent decline in earnings.

Succession of Chief Executive Officer at Giga-tronics Could Result In a Less
Supportive Management Perspective for ASCOR
    

         Mr. George H. Bruns, Jr. may decide over the next year or two to bring
in a new Chief Executive Officer to manage Giga-tronics. Mr. Bruns joined the
Company in January of 1995, originally with the intention to just stay a short
time period. Due to Mr. Bruns many other business interests he may need to
reduce his time spent at Giga-tronics. Since Mr. Bruns has been associated with
ASCOR since its inception, a new Chief Executive Officer at Giga-tronics may not
be as effective at managing the combined entities.

                            GIGA-TRONICS INCORPORATED

     Giga-tronics designs, manufactures and markets microwave and radio
frequency signal generation and power measurement instruments for the
electronics test and measurement equipment industry. These products are used in
the design, production, repair, and maintenance of telecommunications, radar,
electronic warfare, and transportation systems. Giga-tronics has approximately
145 employees and all functions of the Company operate out of a 47,000 square
foot facility in San Ramon, California. The Company books a mixture of
commercial and government-related orders. In the past three fiscal years, sales
related to U.S. Government agencies accounted for 31%, 26%, and 27% of total net
sales. It is anticipated that sales to U.S. Government agencies will remain
significant in fiscal 1997, even though the outlook for defense-related orders
continues to be soft. Shipments are realized to domestic and international
customers.

     On March 30, 1996, Giga-tronics had a backlog of approximately $6,112,000
compared to $10,154,000 at March 25, 1995. The Company shares the market with
competitors that are larger and that have greater financial, engineering and
marketing resources than the Company. The future success of the Company is
dependent on its ability to steadily incorporate advancements in semiconductor
and related microwave component technologies into its new products.

     The Company was incorporated in 1980, and operated previously out of
locations in Pleasant Hill, California and Sunnyvale, California. Currently, the
San Ramon facility is the only location, which is occupied under a lease with
ten years remaining.

     Two of the fours members of the Giga-tronics  Board of Directors,  Mr.
George H. Bruns, Jr., and Mr. James A. Cole, are also members of the ASCOR Board
of Directors. Additionally, Mr. Bruns, Mr. Cole, and Mr. Robert C. Wilson (also
on the Giga-tronics Board) hold varying amounts of ASCOR Shares and ASCOR
Convertible Securities. Each shareholder is urged to read this Proxy in its
entirety for more details.

                                   ASCOR, INC.

     ASCOR designs, manufactures and markets an extensive line of switching and
connecting devices that link together many specific purpose instruments that are
part of automatic test systems. ASCOR offers a family of Switching and Interface
Test Adapters as standard VXI configured products. Additionally, it provides
complete systems integration services to the Automatic Test Equipment (ATE)
market.

     In the past three fiscal years, defense-related orders accounted for 87%,
87%, and 100% of net sales in the twelve-month periods ending March, 1996, 1995,
and 1994, respectively. Management anticipates that sales to defense contractors
will remain significant in fiscal 1997, even though the outlook for
defense-related orders continues to be soft. Shipments are realized only to
domestic customers.

     On March 30, 1996, ASCOR had a backlog of approximately $2,742,000 compared
to $3,023,000 at March 25, 1995. The Company shares the market with competitors
that are larger and that have greater financial, engineering, and marketing
resources than the Company. The future success of the Company is dependent on
its ability to steadily incorporate advancements in semiconductor and related
microwave component technologies into its new products.

     ASCOR was founded and incorporated in 1987. It has approximately 50
employees and all functions of the Company operate out of a leased facility with
12,160 square feet in Fremont, California. The lease for the facility expires on
January 31, 1998.

     Two of the five members of the ASCOR Board of Directors,  Mr. George H.
Bruns, Jr., and Mr. James A. Cole, are also members of the Giga-tronics Board of
Directors. Additionally, Mr. Bruns, Mr. Cole and Mr. Robert C. Wilson (also on
the Giga-tronics Board) hold varying amounts of ASCOR Shares and ASCOR
Convertible Securities. Each shareholder is urged to read this Proxy in its

                                   THE MERGER

Description of the Merger

     At the Effective Time, (i) Acquisition Corp. will be merged with and into
ASCOR and ASCOR will become a wholly owned subsidiary of Giga-tronics; (ii) each
(a) share of ASCOR Common Stock and ASCOR Preferred Stock outstanding
immediately prior to the Merger (other than ASCOR Shares held by shareholders
who have perfected and not withdrawn their right to seek appraisal of their
shares under applicable California law) and (b) outstanding ASCOR Convertible
Security will be converted into the right to receive a pro rata portion of an
aggregate of 724,986 Shares of Giga-tronics Common Stock to be issued in the
Merger. In determining the Exchange Ratio which holders of ASCOR Securities will
be entitled to receive, all ASCOR Convertible Securities will be treated as
having been converted or exercised into ASCOR Shares. Any ASCOR Convertible
Securities which are considered "out-of-the-money" will be assumed by
Giga-tronics and will be exercisable for Giga-tronics Common Stock as adjusted
by the Merger. Shares of Giga-tronics Common Stock attributable to ASCOR
Convertible Securities which are assumed by Giga-tronics will be retained by
Giga-tronics from the Merger Consideration pending their exercise. See "THE
REORGANIZATION AGREEMENT AND RELATED AGREEMENTS - The Reorganization Agreement -
The Exchange Ratio and ASCOR Convertible Securities." See "DISSENTERS' APPRAISAL
RIGHTS."

   
     A maximum of 724,986 shares of Giga-tronics Common Stock will be issuable
in the Merger, including (a) shares issuable in respect of ASCOR Convertible
Securities which are assumed, which shares will be retained by Giga-tronics if
such securities expire unexercised, (b) fractional shares, (c) shares issuable
in respect of ASCOR Shares for which dissenters' appraisal rights (see " -
DISSENTERS' APPRAISAL RIGHTS") are perfected, and (d) shares deemed surrendered
upon exercise of ASCOR Convertible Securities for which a deemed net exercise
has occurred. See "THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS - The
Reorganization Agreement - The Exchange Ratio." The Merger will be effective at
the time the agreement of merger (the "Agreement of Merger" the form of which is
attached to the Reorganization Agreement as Exhibit 1.01 - See Annex C) is filed
with the Secretary of State of the State of California. Assuming all conditions
to the Merger are met or waived prior thereto, it is anticipated that the
Effective Time will occur not later than July 30, 1996.

Voting and Proxies - Giga-tronics

     Date, Time and Place of Special Meeting. The Special Meeting is scheduled
to be held at 10:00 a.m., local time, on Wednesday, June 26, 1996, at the
Giga-tronics facilities at 4650 Norris Canyon Road, San Ramon, California 94583.
    

   
     Record Date and Outstanding Shares. Only holders of record of shares of
Giga-tronics Common Stock at the close of business on June 14, 1996 (the "Record
Date") may vote at the Special Meeting or at any adjournments or postponements
thereof. As of the Record Date, there were 2,642,970 shares of Giga-tronics
Common Stock outstanding, the only class of securities of the Company entitled
to vote at the Special Meeting, held by approximately 1,089 shareholders of
record. Each shareholder is entitled to one vote for each share registered in
the shareholder's name on the Record Date.
    

     Voting Proxies. Many of the Company's shareholders may be unable to attend
the Special Meeting. Therefore, Giga-tronics' Board of Directors is soliciting
proxies so that each shareholder has the opportunity to vote on the proposals to
be considered at the Special Meeting. When a proxy card is returned properly
signed and dated, the shares represented thereby will be voted in


                                      -22-
<PAGE>   30
accordance with the instructions on the proxy card. However, if a shareholder
does not return a signed proxy card, his or her shares will not be voted by the
proxies. Shareholders are urged to mark the boxes on the proxy card to indicate
how their shares are to be voted. If a shareholder returns a signed proxy card
and a choice is not specified, the shares represented by that proxy card will be
voted in favor of the Merger and may also be voted in the proxy holder's
discretion on such other business as may properly come before the meeting or any
adjournments or postponements thereof, except that shares represented by proxies
which have been voted "against" the Reorganization Agreement and the Merger will
not be used to vote "for" postponement or adjournment of the Special Meeting for
the purpose of allowing additional time for soliciting additional votes "for"
the Reorganization Agreement and the Merger. See " - Vote Required.".

   
     Shareholders of Giga-tronics who execute proxies retain the right to revoke
them at any time before they are voted. Any proxy given by a shareholder may be
revoked (i) by duly executing and delivering a later proxy prior to the exercise
of such proxy, (ii) by giving notice of revocation in writing to the Secretary
of the Company prior to the meeting, at 4650 Norris Canyon Road, San Ramon,
California 94583, or (iii) by attending the Special Meeting and voting in
person.

     Vote Required. A quorum for the transaction of business at the meeting
consists of holders of the majority of the outstanding shares of the
Giga-tronics' Common Stock, present in person or by proxy. For purposes of
determining the presence of a quorum, abstentions, but not broker non-votes,
will be counted. In the event that less than a majority of the outstanding
shares are present at the Special Meeting, either in person or by proxy, a
majority of the shares so represented may vote to adjourn the Special Meeting
from time to time without further notice, other than announcement at the Special
Meeting, until a quorum shall be present or represented.

     The affirmative vote of holders of at least a majority of the outstanding
shares of Common Stock of Giga-tronics as of the Record Date is required to
approve and adopt the Reorganization Agreement and the transactions contemplated
thereby. Under the California Corporate Law, in determining whether the proposal
regarding the adoption of the Reorganization Agreement has received the
requisite number of affirmative votes, abstentions will be counted and will
have the same effect as a vote against such proposal. Broker non-votes which
are not counted for any purpose will have no effect on the proposal.

     At the Close of Business on June 14, 1996 directors and officers of
Giga-tronics were entitled to vote 438,538 shares of Giga-tronics' Common Stock
representing 16.5% of the total shares entitled to vote at the Special Meeting.

     Solicitation of Proxies; Expenses. The cost of solicitation, including the
cost of preparing and mailing the Notice of Special Meeting of Shareholders and
this Joint Proxy Statement/Prospectus, will be paid by Giga-tronics.
Solicitation will be made primarily by mailing this Joint Proxy
Statement/Prospectus to all shareholders entitled to vote at the Special
Meeting. Proxies may be solicited by officers and regular employees, but at no
compensation in addition to their regular compensation as employees.
Giga-tronics may reimburse brokers, banks and others holding shares in their
names for third parties for the cost of forwarding Joint Proxy
Statement/Prospectus to and obtaining proxies from third parties. In addition,
while Giga-tronics has no present intention to retain anyone to assist in
soliciting proxies, Giga-tronics may do so if it deems such action necessary.
    

ASCOR Shareholder Consent Solicitation - Vote Required

     Consent Solicitation. ASCOR will deliver copies of this Joint Proxy
Statement/Prospectus to all of its shareholders with a request that they execute
a written consent approving the Merger. Pursuant to California Corporate Law,
the Merger will be deemed approved by ASCOR's shareholders at such time as there
have been filed with the secretary of ASCOR consents relating to the vote of
ASCOR shareholders required to approve the Merger. See " - Vote Required." Under
California Corporate Law ASCOR shareholders who have previously delivered a
written consent

                                      -23-
<PAGE>   31
approving the Merger may revoke the consent by a writing received by ASCOR prior
to the time that written consents of the number of votes required to authorize
the Merger are received by the secretary of ASCOR. Such revocation is effective
upon receipt by the secretary of ASCOR.

     Vote Required. Approval of the Merger by ASCOR's shareholders requires the
written consent of persons holding a majority of the votes entitled to be cast
by holders of outstanding (a) ASCOR Common Stock voting as a class, (b) ASCOR
Preferred Stock voting as a separate class and (c) ASCOR Common Stock and ASCOR
Preferred Stock voting together as a single class. Each share of ASCOR Common
Stock is entitled to one vote and each share of ASCOR Preferred Stock is
entitled to such number of votes as the number of shares of ASCOR Common Stock
into which such share of ASCOR Preferred Stock is convertible. At the close of
business on May 20, 1996, directors and officers of ASCOR and their affiliates,
in the aggregate held ASCOR Common Stock and ASCOR Preferred Stock entitled to
cast 10,546,254 votes, representing 75.0% of the total votes entitled to be
voted by ASCOR Common Stock and ASCOR Preferred Stock voting together as a
single class, by written consent with respect to the Merger.

Background of the Merger

   
     Since two of the four Giga-tronics  Directors (Mr. George H. Bruns, Jr.,
and Mr. James A. Cole) are also Directors of ASCOR, Giga-tronics has known about
ASCOR since its incorporation in 1987. However, discussion of the proposed
merger was initiated by Mr. Jeff Lum, President of ASCOR, and Mr. Bliss McCrum,
an ASCOR investor and ASCOR Board member. For Mr. Jeff Lum, primary reasons
included the need for capital, the advantage of being associated with a larger
company, and the need for access to international markets. For Bliss McCrum, and
the other venture capitalists (ASCOR investors), there is a need for medium term
liquidity.

     Over the past two years, the Giga-tronics Board has discussed the pursuit
of various acquisition candidates which would potentially be synergistic with
the Giga-tronics product line, but never reached any agreements on a
transaction. There also were no formal negotiations conducted or offers made or
rejected for any acquisition candidates. There was significant contact and
discussions with three companies, but negotiations were not initiated due to
various negative factors associated with one or all of the candidates, including
but not limited to geography (too far from Giga-tronics), inconsistent financial
performance, limited history, and the potential purchase price not appearing
financially justifiable. Due to the extremely high costs of completing
acquisitions, only strong acquisition targets are pursued, and only one
acquisition is contemplated at a given time. In September and October of 1995,
the idea of a Giga-tronics/ASCOR merger was discussed at both Companys'
respective Board meetings. It was felt that if such a merger were otherwise
possible, it would substantially broaden the product base and strengthen the
technical capability of Giga-tronics while providing marketing leverage and
added financial resources for ASCOR.

     The discussions at the September 27, 1995 ASCOR Board meeting included
general discussion concerning Giga-tronics compatibility in the areas of
technology, products, and markets. These discussions were held among Mr. George
H. Bruns, Jr., Mr. James A. Cole, Mr. Jeffrey Lum, Mr. Bliss McCrum, and Mr.
Steven Herrick. There was a brief review of the historical financials for
Giga-tronics, as well as the projections for fiscal year 1996 ending March 30,
1996. The discussions held at the October 23, 1995 Giga-tronics Board meeting
included general discussion concerning ASCOR compatibility in the areas of
technology, products and markets. These discussions were held among Mr. George
H. Bruns, Jr., Mr. James A. Cole, Mr. Edward D. Sherman, and Mr. Robert C.
Wilson. There was never any discussion or consideration given to the option of
contracting for or seeking to enter into a licensing agreement for the
desired VXI architecture.
    

     In subsequent discussions between the two companies, it was felt that the
commonality of interests and purpose suggested a Merger based upon relative,
rather than absolute values.

     At the November 15, 1995 ASCOR Board meeting, there was a more detailed
discussion about the advantages of a merger with Giga-tronics. These discussions
included the need for cash by ASCOR to re-pay debt, while Giga-tronics was in a
cash surplus position. While Giga-tronics had a very strong balance sheet, the
earnings stream of Giga-tronics would benefit from a merger with ASCOR. The
future growth potential of both companies was discussed. It was decided that a
group representing ASCOR (Mr. Jeffrey Lum, Mr. Fred Chu, Mr. James A. Cole, and
Mr. Bliss McCrum) would formulate a set of relative values for ASCOR and
Giga-tronics after the Merger. Meanwhile, Giga-tronics (represented by Mr.
George H. Bruns, Jr.) would also formulate a

                                      -24-
<PAGE>   32
proposal. Shortly thereafter, Mr. Jeffrey Lum submitted an ASCOR proposal
including post-merger values of 69% Giga-tronics and 31% ASCOR. Mr. Bruns
indicated that this proposal would not be acceptable because the recent history
(3 years) of the two companies had been given too much weight. Since the recent
earnings history of ASCOR had been stronger than Giga-tronics, but Giga-tronics
had very strong earnings prior to the most recent 3 years through fiscal 1995,
more work was needed to reach an equitable ratio of post-merger ownership.

     At the December 6, 1995 Giga-tronics Board meeting, Mr. George H. Bruns,
Jr., Mr. James A. Cole, Mr. Edward D. Sherman, Mr. Robert C. Wilson and Mr.
Gregory L. Overholtzer (Chief Financial Officer and Secretary of Giga-tronics)
reviewed in detail the five-year history of Giga-tronics and ASCOR, one-year
projections for both companies, projected ASCOR cash flow for fiscal 1996, the
capitalization of ASCOR, and the positive/negative attributes of both companies.
While ASCOR had good technology, good growth, excellent management, and was in a
good market, it also was dependent on large contracts, had a large concentration
of its sales with a few customers, its sales were all related to the U.S.
defense industry, it was going to need cash over the next year, and the ratio of
earnings to sales were projected to decline somewhat in the fiscal year 1996
ending September 30. Though Giga-tronics had some product lines which were aging
with poor profit margins, it also had a broad market base, more commercial
accounts than defense oriented, a strong field organization, a very strong
balance sheet and cash position, and a strong earnings history if at least the
prior 5 years were included. A post-combination value ratio of ASCOR to
Giga-tronics of 22% to 78% was approved by the Giga-tronics Board. On December
7, this proposal was communicated by Mr. George H. Bruns to the ASCOR
negotiating team. Mr. Bruns communicated to ASCOR that the Board of Giga-tronics
believed that this ratio was equitable and fair to ASCOR, as well as to
Giga-tronics Shareholders for all the reasons outlined above, and that if ASCOR
was not in agreement, Giga-tronics would seek other synergistic acquisitions to
pursue.

     Over the next few weeks, various proposals with different post-combination
value ratios were presented to Mr. George H. Bruns, Jr. by Mr. James A. Cole and
Mr. Bliss McCrum. These proposals were reviewed and rejected by Giga-tronics. By
mid-December, after due consideration of past and potential future growth,
profitability, technical strengths, financial strength and organizational
compatibility, it was mutually agreed that a post combination value ratio of
ASCOR to Giga-tronics would be 22% to 78%. Based upon the number of outstanding
shares of Giga-tronics common stock of 2,569,920 as of December 1, 1995, the
preceding ratios suggested that ASCOR thus had an equivalent value of 724,986
Giga-tronics shares.

     The Board of Directors of Giga-tronics felt it was important that the
proposed merger be accounted for as a pooling-of-interests. In late December,
the Giga-tronics finance group and the Giga-tronics auditors, KPMG Peat Marwick
LLP ("KPMG") began financial due diligence and an analysis of poolability. Upon
satisfactory completion of these tasks in late March, 1996, an audit of ASCOR by
KPMG was arranged and conducted in April 1996. Upon completion of the audit, the
"Reorganization Agreement" was executed on May 2, 1996.

     On May 20, 1996 Giga-tronics and ASCOR executed the Letter Agreement
pursuant to which Giga-tronics agreed to sue its best faith efforts to effect
the registration pursuant to federal securities laws of the Giga-tronics Common
Stock to be issued in the Merger on a Form S-4 registration statement. See "THE
REORGANIZATION AGREEMENT AND RELATED AGREEMENTS - Letter Agreement."

Giga-tronics' Reasons for the Merger; Recommendations of Giga-tronics' Board of
Directors

     The Board of Directors of Giga-tronics believes that the terms of the
Reorganization Agreement and the transactions contemplated thereby are fair to,
and in the best interest of, Giga-tronics Incorporated and its shareholders. In
making that determination, the Giga-tronics Board of Directors considered the
following factors: (i) ASCOR's business prospects and recent results of

                                      -25-
<PAGE>   33
operations and financial position, (ii) the benefit of having access to certain
of ASCOR's technology and technical resources, (iii) the potential synergistic
benefits derived from the coordination of sales and marketing strategies, and
(iv) the ease of integration and exchange of ideas due to long-term
familiarity. Mr. George H. Bruns also had numerous meetings with Mr. Roger
Wood, the financial advisor, to discuss his analysis of the proposed merger
and his findings regarding the fairness of the merger consideration.

     The Board of Directors of Giga-tronics considered ASCOR's working capital
position, anticipated cash flow from operations, available cash balances and the
quality of ASCOR's customer base.

     The Giga-tronics Board also considered the impact that access to ASCOR's
engineering personnel could have on advancing Giga-tronics products and
technology. The Board noted that Giga-tronics and ASCOR technology was
complementary and that ASCOR possessed certain VXI and switching capabilities
required by Giga-tronics in developing new products for its markets.

     ASCOR's understanding of high bandwidth electronic switching could help
broaden the Giga-tronics microwave product line by allowing Giga-tronics to
incorporate the ASCOR switch technology into its products. ASCOR's products
could help Giga-tronics realize new market potential for its microwave products
through the use of its VXI architecture. The signal generator product offering
of the combined Company could enable the combined Giga-tronics to be a more
powerful force in the microwave test instrument marketplace. ASCOR has
established strong relationships with some very large companies that may also be
potential customers for signal generators and power measurement devices produced
by Giga-tronics. In summary, the acquisition of ASCOR by Giga-tronics offers the
opportunity to expand one of its oldest product lines by infusing new technical
concepts into the product and providing market synergy with an important
customer base. Notwithstanding certain distribution channel risks (see "RISK
FACTORS - Distribution Channel Conflicts"), the Giga-tronics sales reps may also
enable the ASCOR product line to realize more sales domestically, and establish
an international customer base as well (currently there are no direct
international sales).

     While the pre-Merger Giga-tronics balance sheet is very strong,
Giga-tronics' earnings as a percentage of sales are lower than ASCOR's earnings
as a percentage of sales because Giga-tronics generally has more mature
products with relatively lower margins. ASCOR's earnings as a percent of sales
are relatively high. With the income streams of the entities combined, and the
realization of product, market, and technical synergies noted above, the
combined Giga-tronics company could realize an improved earnings stream while
maintaining a very strong balance sheet.

     The Board of Directors of Giga-tronics also believes that Mr. George H.
Bruns, Jr. and Mr. James A. Cole can, because of their long-term familiarity
with both organizations, ease integration and the exchange of ideas between the
two companies.

     In approving the Merger, Giga-tronics also took into account the potential
conflicts of interest of Mr. George H. Bruns, Jr., Mr. James A. Cole, and Mr.
Robert C. Wilson because of their shareholdings in both Giga-tronics and ASCOR.

     The Board of Directors of Giga-tronics considered the positive and negative
factors as a whole and concluded that the negative factors were outweighed by
the positive factors as a whole and accordingly determined that the Merger is
fair to, and in the best interests of, the shareholders of Giga-tronics. The
negative factors considered included the dependence on key personnel,
distribution channel risks, reliance on a single family of products, reliance on
major contracts and a few number of customers, growth management, and future
sales of common stock after the Merger.

     In view of the wide variety of factors considered by the Giga-tronics Board
of Directors, it did not find it practicable to quantify, or otherwise attempt
to assign relative weights to the specific factors considered in making its
determination. Consequently the Giga-tronics' Board of Directors did not
quantify the assumptions and results of its analysis in reaching its
determination that the Merger is fair to, and in the best interests of,
Giga-tronics' shareholders.

ASCOR Reasons for the Merger - Recommendations of ASCOR's Board of Directors

     The Board of Directors of ASCOR believes that the terms of the proposed
Reorganization Agreement and the transactions contemplated thereby are fair to,
and in the best interest of, ASCOR, Inc. and its shareholders. In making that
determination, the ASCOR Board of Directors considered the following factors:
(i) Giga-tronics' business prospects and recent results of operations and
financial position, (ii) the benefit of having access to certain of
Giga-tronics' sales and marketing resources, (iii) the ease of integration and
exchange of ideas due to long-term familiarity, (iv) the benefit of having
access to certain management resources to help sustain ASCOR's potential sales
growth, and (v) increased liquidity for holders of ASCOR stock and stock
equivalents.

     The Board of Directors of ASCOR considered Giga-tronics' working capital
position, anticipated cash flow from operations, available cash balances and the
quality of Giga-tronics' customer base. They believed that Giga-tronics' strong
balance sheet would permit available cash to assist in funding potential growth
of ASCOR.

     The ASCOR Board believed that, notwithstanding the distribution channel
risks discussed above (see "RISK FACTORS - Distribution Channel Conflicts"), the
Giga-tronics sales reps and Giga-tronics sales and marketing group could enable
the ASCOR product line to realize more sales domestically, and establish an
international customer base as well (currently there are no direct international
sales).
   

     The Board of Directors of ASCOR believes that Mr. George H. Bruns, Jr., and
Mr. James A. Cole can, because of their long-term familiarity with both
organizations, ease integration and the exchange of ideas between the two
companies. With two Board members being common to ASCOR and Giga-tronics, ASCOR
will have the benefit of Board familiarity with ASCOR after the merger. This
familiarity will prevent short-term decisions being made after the merger that
might have poor long-term consequences for ASCOR. Two of the four post-merger
Giga-tronics Directors already understand the ASCOR business, and have the
product knowledge to immediately implement post-merger decisions that would
benefit ASCOR as well as Giga-tronics. These Board members have an in-depth
perspective on ASCOR operations.
    

     If ASCOR experiences a high sales growth rate, the senior management of
Giga-tronics (a Company with five times the revenue) can be helpful in
identifying and solving risks and issues related to larger companies. These
benefits accrue to ASCOR with no incremental cost being incurred.

     Since Giga-tronics is publicly traded on NASDAQ, the holders of ASCOR stock
and stock equivalents would have increased liquidity after the merger has been
consummated and their stock is tradeable after expiration of holding periods
required under federal securities law or sold in a registered offering of
Giga-tronics stock pursuant to their rights under the Registration Rights
Agreement.
   

     The Board of Directors of ASCOR considered the positive and negative
factors as a whole and concluded that the negative factors were outweighed by
the positive factors as a whole and accordingly determined that the Merger is
fair to, and in the best interest of, the shareholders of ASCOR. The negative
factors considered included the limited liquidity for ASCOR shareholders
(historically thin Giga-tronics trading volume), the softness in recent
Giga-tronics order intake, and the future succession of the Chief Executive
Officer at Giga-tronics. In approving the Merger, the Board of Directors of
ASCOR also took into account the potential conflicts of interest of Mr. George
H. Bruns. Jr., and Mr. James A. Cole because of their shareholdings and Board
positions in both ASCOR and Giga-tronics.
    

     THE BOARD OF DIRECTORS OF ASCOR RECOMMENDS THAT ASCOR SHAREHOLDERS VOTE FOR
APPROVAL OF THE MERGER AND EXCHANGE OF ALL OUTSTANDING ASCOR COMMON STOCK FOR
GIGA-TRONICS COMMON STOCK PURSUANT TO THE TERMS OF THE REORGANIZATION AGREEMENT.

Opinion of Financial Advisor
   

      On April 12, 1996, the Giga-tronics Board of Directors retained Wood,
Warren and Company to render a fairness opinion. On May 3, 1996, the
Giga-tronics Board of Directors received Wood, Warren & Co.'s Opinion dated May
2, 1996, which provided that as of such date that the Exchange Ratio to be
applied in the Merger is fair, from a financial point of view, to Giga-tronics.
Wood, Warren & Co.'s opinion is directed only to the financial terms of the
Reorganization Agreement and does not constitute a recommendation to any
shareholder of Giga-tronics as to how such shareholder should vote at the
Giga-tronics Special Meeting. No limitations were placed on Wood, Warren & Co.
by the Board of Directors of Giga-tronics with respect to the investigation made
or the procedures followed in preparing and rendering its opinion. A copy of
Wood, Warren & Co.'s written opinion and summary of significant analysis is
attached as Annex E hereto and should be read in its entirety for a description
of the procedures followed, matters considered, assumptions made and methods
employed by Wood, Warren & Co.
    

     In arriving at its opinion, Wood, Warren & Co.: (i) reviewed the Merger
Agreement and the Joint Proxy Statement/Prospectus dated May 2, 1996 and such
other information that was publicly available or was furnished to it by the
Company or ASCOR, (ii) reviewed financial statements for the five years ending
March 30, 1996 and other financial information, including forecasts, and
operating data of Giga-tronics and ASCOR furnished to Wood, Warren & Co. by the
companies, (iii) considered the historical stock prices and trading volumes of
the common stock of the Company, (iv) reviewed the prices and premiums paid in
other business combinations, (v) and prepared a discounted cash flow analysis of
ASCOR. In addition, Wood, Warren & Co. held discussions with the senior
management of Giga-tronics and ASCOR regarding the strategic rationale for, and
benefits of, the Merger and the past and current business operations, financial
condition and future prospects of the respective companies on a stand alone
basis and as combined in the Merger, and undertook such other financial analyses
as it deemed appropriate for purposes of this opinion.

     The following paragraphs summarize the significant analyses performed by
Wood, Warren & Co. in arriving at its opinion. The information presented below
is based on the financial condition of the Company and ASCOR as of a date or
dates shortly before the date of its opinion (May 2, 1996). The closing price of
Giga-tronics common stock on May 2, 1996, as reported by NASDAQ National
Marketing System, was $8.25. Based on that price and the assumption that
Giga-tronics will issue the maximum 724,986 shares of its common stock in the
Merger, the enterprise value of ASCOR was approximately $5.6 million.

     Analysis of Selected Transactions Analysis. Wood, Warren & Co. compared the
proposed Merger with selected merger and acquisition transactions. This analysis
included 32 technology company transactions. In examining these transactions,
Wood, Warren & Co. analyzed certain income statement and balance sheet
parameters of the acquired company relative to the consideration offered.
Multiples analyzed included consideration offered to historical revenue, to
historical cash flow from operations, to historical earnings before interest and
taxes, to historical net income, and to historical book value. Based on the
analysis of the selected merger and acquisition transactions, ASCOR's implied
equity value ranged from approximately $5.0 million to approximately $16.7
million.

     Discounted Cash Flow Analysis. Wood, Warren & Co. analyzed the theoretical
valuation of ASCOR based on projections prepared by the managements of
Giga-tronics and ASCOR. To estimate the total present value of ASCOR's business,
Wood, Warren & Co. discounted to present value the business as reflected in the
financial performance estimates using discount rates ranging from 25% to 40%.
The terminal value was based on multiples of 5.5 and 7.5 times projected
earnings before interest and taxes for fiscal 2001. Based on the discounted cash
flow analysis, ASCOR's enterprise value ranged from approximately $4.4 million
to approximately $9.2 million.

   
     Pro Forma Analysis. Wood, Warren & Co. analyzed the pro forma impact of the
proposed Merger on Giga-tronics earnings per share. In conducting its analysis,
Wood, Warren & Co. relied upon the financial projections for the fiscal years
ending March, 1997 through 2001 provided by the management of Giga-tronics and
ASCOR, respectively. The analysis indicated that earnings per share of the pro
forma combined company would be higher in the first fiscal year after the Merger
and higher thereafter through fiscal 2001 than comparable projections for
Giga-tronics as a stand-alone company.
    

     Stock Trading History Analysis. Wood, Warren & Co. examined the trading
history in terms of both price and volume for periods of time ranging from six
months, one year, three years and five years. Wood, Warren & Co. noted that the
Giga-tronics' average price per share was $7.76,

                                      -28-
<PAGE>   36
$7.65, $6.64, and $6.84, respectively. In addition, Wood, Warren & Co. analyzed
the volume of Giga-tronics shares traded at different prices over the same time
periods. Wood, Warren & Co. noted that, for each period analyzed, approximately
48% to 64% of the trading volume was at prices below the six month average price
per share of $7.76.

     Contribution Analysis. Wood, Warren & Co. analyzed the contribution of each
of Giga-tronics and ASCOR to certain financial statement categories of the pro
forma combined company, including revenue, gross profit, operating income, and
net income. The review was made for the three years ended March 30, 1996. This
contribution analysis was then compared to the pro forma ownership percentage of
ASCOR's shareholders (approximately 22%) in the pro forma combined company. In
gross profits and earnings, ASCOR's contribution exceeded that of its
approximate ownership in the pro forma combined company.

     The preparation of a fairness opinion involves various determinations as to
the most appropriate and relevant quantitative and qualitative methods of
financial analyses and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. No company or transaction used in the above analysis is
closely comparable to Giga-tronics or ASCOR or the Merger. Accordingly, Wood,
Warren & Co., believes its analyses must be considered as a whole and that
considering any portion of such analyses and of the factors considered, without
considering all analyses and current factors, could create a misleading or
incomplete view of the process underlying the opinion. Any estimates contained
in these analyses are not necessarily indicative of actual values or predictive
of future results or values, which may be significantly more or less favorable
than as set forth therein. In addition, analyses relating to the value of
businesses do not purport to be appraisals or to reflect the prices at which
businesses actually may be sold.

   
Conflicts of Interest
    

     In considering the recommendations of the Board of Directors of
Giga-tronics with respect to the issuance of shares of Giga-tronics Common Stock
pursuant to the Reorganization Agreement, shareholders of Giga-tronics should be
aware that certain members of Giga-tronics' Board of Directors and the Chief
Executive Officer of Giga-tronics have certain interests in the Merger that are
in addition to the interests of shareholders of Giga-tronics generally. In
particular, three of the four Giga-tronics Board members, including Mr. George
H. Bruns, Jr., Chairman and Chief Executive Officer, beneficially own shares of
ASCOR Common or Preferred Stock or ASCOR

                                      -29-
<PAGE>   37
warrants (which shares shall or warrants may be converted into shares of
Giga-tronics Common Stock in connection with the Merger), as set out in the
table below. Two of the four Giga-tronics Board members, Mr. George H. Bruns,
Jr., and Mr. James A. Cole, also participate on the ASCOR Board of Directors
(which is comprised of five members in total).

     These interests were considered, among other matters, in approving the
Reorganization Agreement and the transactions completed thereby.

Employee Benefit Plan

     The current ASCOR benefit plan, which is fairly similar to the current
Giga-tronics benefit plan, will be retained. In the future, both companies may
operate under the current Giga-tronics benefit plan if that is desirable from a
cost-benefit trade-off. The differences in the two plans are as follows. Medical
and Dental insurance costs and providers are different for the companies. Cost
to the Giga-tronics' employees is somewhat higher, though there are more
coverage options to choose from. Both companies have 401K plans with company
contributions based on employee participation. The rate of corporate matching
for Giga-tronics is higher, but the cap on employer matching is lower, than the
ASCOR Plan.

           STOCK OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
   

     The following table sets forth certain information concerning (i) persons
or entities anticipated to hold 5% or more of Giga-tronics Common Stock after
the Merger, (ii) anticipated ownership of Giga-tronics by each anticipated
director and executive officer of Giga-tronics individually, and by all
directors and executive officers of Giga-tronics as a group, (iii) anticipated
ownership of Giga-tronics by each current ASCOR director and executive officer,
in each case based upon ownership by such person of Giga-tronics Common Stock
and ASCOR Common Stock/Common Stock Equivalents as of June 14, 1996 and after
giving effect to the Merger. The estimated ASCOR to Giga-tronics exchange ratio
of 18.246 to 1 was determined by dividing the Merger Consideration by the number
of ASCOR Common Shares and equivalents outstanding as of the date of this Joint
Proxy Statement/Prospectus. The actual Exchange Rate at the Effective Time
should be approximately the same figure.

Accounting Treatment

     The Merger is intended to qualify as a pooling-of-interests for accounting
and financial reporting purposes. Under this method of accounting, the assets
and liabilities of Giga-tronics and ASCOR will be carried forward to the
combined company (combined Giga-tronics) at their recorded amounts, income of
the combined company will include income of Giga-tronics and ASCOR for the
entire fiscal period in which the combination occurs (fiscal 1997 ending March
29, 1997) and the reported income of the separate companies for prior periods
will be combined and restated as income of the combined company. Expenses of the
Merger, which are estimated to be $250,000, will be charged to expense as
incurred in fiscal years 1996 and 1997.

     Pursuant to the Reorganization Agreement, Giga-tronics and ASCOR are
required to exercise their best efforts to cause each of their respective
affiliates to execute a written agreement as of the Effective Time of the Merger
to the effect that such person has not transferred shares of Common Stock of
Giga-tronics and Common or Preferred Stock of ASCOR within the preceding 30 days
and will not transfer any shares of combined Giga-tronics Common Stock prior to
the date that combined Giga-tronics publishes results covering at least 30 days
of combined operations of Giga-tronics and ASCOR. See "THE REORGANIZATION
AGREEMENT AND RELATED AGREEMENTS - The Reorganization Agreement and Affiliates
Agreements."

Certain Federal Income Tax Consequences
   

     In the opinion of Brobeck Phleger & Harrison LLP ("Brobeck") , the
following discussion describes the material Federal Income tax considerations of
the Merger to ASCOR and to the shareholders of ASCOR under existing federal
income tax law, which is subject to change, possibly retroactively. This
discussion does not describe all aspects of federal Income taxation which may be
relevant to particular stockholders in light of their personal circumstances,
such as holders whose stock was acquired pursuant to the exercise of an employee
stock option or otherwise as compensation, nor to stockholders who are subject
to special treatment under the Federal income tax laws (for example, financial
institutions, insurance companies, tax-exempt organizations, broker-dealers and
foreign taxpayers); nor does it discuss any aspects of state, local, or foreign
tax law. THIS DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES OF THE MERGER TO
HOLDERS OF ASCOR OPTIONS OR WARRANTS WHICH HAVE NOT BEEN ACTUALLY EXERCISED FOR
ASCOR STOCK PRIOR TO THE MERGER, AND SUCH HOLDERS ARE ADVISED TO CONSULT THEIR 
TAX ADVISORS REGARDING THE FEDERAL, STATE, LOCAL, AND FOREIGN INCOME AND OTHER 
TAX CONSEQUENCES OF THE MERGER. THIS DISCUSSION ALSO DOES NOT DISCUSS THE TAX
CONSEQUENCES OF ANY TRANSACTION OTHER THAN THE MERGER (INCLUDING OTHER
TRANSACTIONS UNDERTAKEN IN CONNECTION W/OR PURSUANT TO THE MERGER).

     The Merger has been structured with the intent that it be tax-free to ASCOR
and shareholders of ASCOR for federal income tax purposes. In the opinion
of Brobeck, based upon certain facts and representations as set forth in such
opinion, the Merger will generally constitute a tax-free reorganization within
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended,
for federal income tax purposes.

     Assuming the Merger qualifies as a reorganization, the following will be 
the general federal income tax consequences of the Merger to the shareholders
of ASCOR:

     1.           No gain or loss will be recognized by holders of ASCOR stock 
                  who exchange their ASCOR stock for Giga-tronics Common Stock,
                  except for any cash received by such stockholders in lieu of 
                  fractional shares of such common stock. A holder of ASCOR
                  stock who receives cash in lieu of fractional shares will 
                  recognize gain or loss to the extent of the difference 
                  between the holder's basis allocable to the fractional share 
                  and the amount of cash received for the fractional share 
                  (assuming the fractional shares are held as capital assets).

    
                                      -38-
<PAGE>   46
   
      2.           The aggregate tax basis of Giga-tronics Common Stock 
                   received by holders of ASCOR stock in the Merger will equal
                   the aggregate tax basis of the ASCOR stock exchanged
                   therefor, reduced by any amount allocable to any fractional
                   share interest for which cash is received.

     3.           Provided that ASCOR stock is held by a holder as a capital as
                  set at the Effective Time, the holding period of the
                  Giga-tronics Common Stock received by the holder of ASCOR
                  stock in the Merger will include the holding period of ASCOR
                  stock.

     4.           No gain or loss will be recognized by ASCOR upon the Merger.

     The opinion of Brobeck expressed herein represents such counsel's best
legal judgment based on existing authorities and is not binding on the Service.
The Service might successfully assert upon an audit of either ASCOR or its
stockholders that different tax consequences result. In addition, this opinion
is based on certain representations made by Giga-tronics, ASCOR and certain
ASCOR shareholders. In the event that such representations are inaccurate,
counsel's opinion could be altered.

     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT APPLY TO PARTICULAR CATEGORIES OF HOLDERS OF ASCOR
STOCK SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS, SUCH AS
FOREIGN HOLDERS AND HOLDERS WHOSE ASCOR STOCK WAS ACQUIRED PURSUANT TO THE
EXERCISE OF AN EMPLOYEE STOCK OPTION OR OTHERWISE AS COMPENSATION. IN ADDITION,
THERE MAY BE RELEVANT STATE, LOCAL OR OTHER TAX CONSEQUENCES, NONE OF WHICH ARE
DESCRIBED ABOVE. ASCOR SHAREHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS TO
DETERMINE THE SPECIFIC TAX CONSEQUENCES OF THE MERGER TO THEM INCLUDING THE
APPLICABILITY AND EFFECT OF FOREIGN, STATE, LOCAL AND OTHER TAX LAWS AND THE
EFFECT OF PROPOSED CHANGES IN THE TAX LAWS.
    

Dissenters' Appraisal Rights

     General. Giga-tronics shareholders and ASCOR shareholders who follow
certain procedures will be entitled, as dissenting shareholders, to have the
"fair value" of their Giga-tronics shares or ASCOR Common Stock or ASCOR
Preferred Stock determined by a court and to be paid in cash therefor pursuant
to California Corporate Law.

     In the event Giga-tronics shareholders holding more than 5% of outstanding
Giga-tronics Common Stock exercise their right of dissent to the Merger (which
percentage is the minimum required for such rights to be executable), preventing
the transaction from being accounted for as a pooling of interests, the
Giga-tronics Board of Directors may elect not to proceed and consummate the
Merger. If ASCOR shareholders exercise their right to dissent to the Merger and
perfect such rights with respect to such amounts of ASCOR Securities as would be
exchanged for 10% or more of the number of shares of Giga-tronics Common Stock
to be issued in the Merger, the transaction will not qualify as a pooling of
interest and the Giga-tronics Board of Directors may elect not to proceed and
consummate the Merger. See "THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS
- - The Reorganization Agreement - Conditions to the Merger."

     Giga-tronics Shareholders. Pursuant to California Corporate Law, as shares
of Giga-tronics Common Stock are traded on NASDAQ, no dissenters' rights of
appraisal are available to any Giga-tronics shareholders unless demands for
payment are filed with respect to 5% or more of the outstanding number of shares
of Giga-tronics Common Stock. If the Merger is approved by the required vote of
the Giga-tronics shareholders and is not abandoned or terminated, any holder of
Giga-tronics Common Stock may, by complying with the provisions of Sections 1300
to and


                                      -39-
<PAGE>   47
including 1312 of the California Corporate Law, require Giga-tronics to purchase
for cash at fair market value the shares owned by such holder which were voted
against the Merger. The fair market value shall be determined as of the day
before the first announcement of the terms of the proposed Merger (which
announcement was made on May 12, 1996) excluding any appreciation or
depreciation in consequence of the proposed Merger.

     THE FOLLOWING IS A BRIEF SUMMARY OF SECTIONS 1300 TO AND INCLUDING 1312,
WHICH SETS FORTH THE PROCEDURES FOR DISSENTING FROM THE MERGER BY GIGA-TRONICS
SHAREHOLDERS AND DEMANDING STATUTORY APPRAISAL RIGHTS UNDER CALIFORNIA LAW. THIS
SUMMARY DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF THE PROVISIONS OF
CALIFORNIA LAW RELATING TO THE RIGHTS OF GIGA-TRONICS SHAREHOLDERS TO AN
APPRAISAL OF THE VALUE OF THEIR SHARES AND IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO SECTIONS 1300 TO AND INCLUDING 1312 OF THE CALIFORNIA CORPORATE
LAW, THE FULL TEXT OF WHICH IS ATTACHED HERETO AS ANNEX F. FAILURE TO FOLLOW
SUCH PROCEDURES EXACTLY COULD RESULT IN THE LOSS OF APPRAISAL RIGHTS.

     The dissenting shareholder wishing to require Giga-tronics to purchase his
shares of Giga-tronics Common Stock must:

     (a)      vote any of the shares the shareholder wishes to be dissenting
              shares against the Merger;

     (b)      make written demand upon Giga-tronics not later than the date of
              the Special Meeting setting forth in the demand such shareholder's
              name and address, and the number and class of shares which the
              shareholder demands that Giga-tronics purchase and a statement as
              to what the shareholder believes the fair market value of such
              shares to have been, based upon the standard set forth above; and

     (c)      submit for endorsement, within 30 days after the date on which the
              notice of approval of the Merger by the Giga-tronics shareholders
              is mailed to such shareholder (which notice must be mailed within
              10 days after the date of approval), at the principal office of
              Giga-tronics, the certificates representing any shares in regard
              to which demand for purchase is being made, with a statement
              regarding which of the shares are dissenting shares.

     Simply voting against approval of the Merger will not be sufficient to
constitute the demand described in clause (b) above.

     Within 10 days after the date of the approval of the Merger, Giga-tronics
will mail to each shareholder who has voted against the Merger and made a proper
written demand for dissenter's rights with respect to Giga-tronics Common Stock
a notice of approval of the Merger together with a statement of the price
determined by Giga-tronics to represent the fair market value of dissenting
shares, and a brief description of the procedure to be followed if the
shareholder desires to exercise dissenters' rights under the California General
Corporation Law. The statement of the price of the shares will constitute an
offer by Giga-tronics to purchase at the price stated therein any dissenting
shares. If Giga-tronics and the dissenting shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder will be entitled to the agreed price plus interest thereon at the
legal rate on judgments from the date of such agreement. Subject to the
provisions of the California General Corporation Law, payment of the fair market
value of the dissenting shares will be made within 30 days after such agreement
or after satisfaction of any statutory or contractual condition, whichever is
later, and upon surrender of the certificates therefor.

                                      -40-
<PAGE>   48
     If Giga-tronics denies that the shares are dissenting shares or if
Giga-tronics and the dissenting shareholder fail to agree upon the fair market
value of the shares, then the dissenting shareholder, within six months after
the date on which notice of approval of the Merger by the Giga-tronics
shareholders is mailed to such shareholder, and not thereafter, may file a
complaint in the Superior Court of Contra Costa County, Martinez, California
requesting the court to determine whether the shares are dissenting shares, or
the fair market value of the dissenting shares, or both, or may intervene in any
pending action for the appraisal of any shares of Giga-tronics Common Stock.

     To the extent that the provisions of Chapter 5 of the California General
Corporation Law (which generally prohibits certain payments to shareholders by
insolvent companies) prevent the payment to any holders of dissenting shares of
the fair market value of such shares, such shareholders will become creditors of
Giga-tronics for the amount that they otherwise would have received in
repurchase of their dissenting shares, plus interest at the legal rate on
judgments until the date of payment, but subordinate to all other creditors in
any liquidation proceeding, such debt to be payable when permissible under the
provisions of Chapter 5 of the California General Corporation Law.

     ASCOR Shareholders. Pursuant to California Corporate Law, if the Merger is
approved by the required vote of the ASCOR shareholders and is not abandoned or
terminated, any holder of ASCOR Common Stock may, by complying with the
provisions of Sections 1300 to and including 1312 of the California Corporate
Law, require ASCOR to purchase for cash at fair market value the shares owned by
such holder for which a written consent to the Merger was not given. The fair
market value shall be determined as of the day before the first announcement of
the terms of the proposed Merger (which announcement was made on May 12, 1996)
excluding any appreciation or depreciation in consequence of the proposed
Merger.

     THE FOLLOWING IS A BRIEF SUMMARY OF SECTIONS 1300 TO AND INCLUDING 1312,
WHICH SETS FORTH THE PROCEDURES FOR DISSENTING FROM THE MERGER BY ASCOR
SHAREHOLDERS AND DEMANDING STATUTORY APPRAISAL RIGHTS UNDER CALIFORNIA LAW. THIS
SUMMARY DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF THE PROVISIONS OF
CALIFORNIA LAW RELATING TO THE RIGHTS OF ASCOR SHAREHOLDERS TO AN APPRAISAL OF
THE VALUE OF THEIR SHARES AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
SECTIONS 1300 TO AND INCLUDING 1312 OF THE CALIFORNIA CORPORATE LAW, THE FULL
TEXT OF WHICH IS ATTACHED HERETO AS ANNEX F. FAILURE TO FOLLOW SUCH PROCEDURES
EXACTLY COULD RESULT IN THE LOSS OF APPRAISAL RIGHTS.

     The dissenting shareholder wishing to require ASCOR to purchase his shares
of ASCOR Common Stock must:

     (a)      not vote any of the shares the shareholder wishes to be dissenting
              shares in favor of the Merger;

     (b)      make written demand upon ASCOR not later than thirty days after
              the date on which the notice of approval of the Merger by ASCOR
              shareholders is mailed to such shareholder (which notice must be
              mailed within 10 days after the date of approval), setting forth
              in the demand such shareholder's name and address, and the number
              and class of shares which the shareholder demands that ASCOR
              purchase and a statement as to what the shareholder believes the
              fair market value of such shares to have been, based upon the
              standard set forth above; and

     (c)      submit for endorsement, within 30 days after the date on which the
              notice of approval of the Merger by the ASCOR shareholders is
              mailed to such shareholder, at the principal office of ASCOR, the
              certificates representing any shares in regard to which demand for
              purchase is being made, with a statement regarding which of the
              shares are dissenting shares.


                                      -41-
<PAGE>   49
     Simply not voting to approve the Merger by not executing the written
consent will not be sufficient to constitute the demand described in clause (b)
above.

     Within 10 days after the date of the approval of the Merger, ASCOR will
mail to each shareholder who did not vote in favor of the Merger with respect
ASCOR Common Stock a notice of approval of the Merger together with a statement
of the price determined by ASCOR to represent the fair market value of
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise dissenters' rights under the California
General Corporation Law. The statement of the price of the shares will
constitute an offer by ASCOR to purchase at the price stated therein any
dissenting shares. If ASCOR and the dissenting shareholder agree that the shares
are dissenting shares and agree upon the price of the shares, the dissenting
shareholder will be entitled to the agreed price plus interest thereon at the
legal rate on judgments from the date of such agreement. Subject to the
provisions of the California General Corporation Law, payment of the fair market
value of the dissenting shares will be made within 30 days after such agreement
or after satisfaction of any statutory or contractual condition, whichever is
later, and upon surrender of the certificates therefor.

     If ASCOR denies that the shares are dissenting shares or if ASCOR and the
dissenting shareholder fail to agree upon the fair market value of the shares,
then the dissenting shareholder, within six months after the date on which
notice of approval of the Merger by the ASCOR shareholders is mailed to such
shareholder, and not thereafter, may file a complaint in the Superior Court of
Contra Costa County, Martinez, California requesting the court to determine
whether the shares are dissenting shares, or the fair market value of the
dissenting shares, or both, or may intervene in any pending action for the
appraisal of any shares of ASCOR Common Stock.

     To the extent that the provisions of Chapter 5 of the California General
Corporation Law prevent the payment to any holders of dissenting shares of the
fair market value of such shares, such shareholders will become creditors of
ASCOR for the amount that they otherwise would have received in repurchase of
their dissenting shares, plus interest at the legal rate on judgments until the
date of payment, but subordinate to all other creditors in any liquidation
proceeding, such debt to be payable when permissible under the provisions of
Chapter 5 of the California General Corporation Law.

                                   SECTION VI

               THE REORGANIZATION AGREEMENT AND RELATED AGREEMENTS

The Reorganization Agreement

     The following is a brief summary of certain provisions of the
Reorganization Agreement, a copy of which is attached as Annex C to this Joint
Proxy Statement/Prospectus and is incorporated herein by reference. This summary
is qualified in its entirety by reference to the full text of the Reorganization
Agreement.

     The Reorganization Agreement provides that, subject to the terms and
conditions of the Reorganization Agreement, at the Effective Time, Acquisition
Corp. will be merged with and into ASCOR, and the separate corporate existence
of Acquisition Corp. will thereupon cease. ASCOR will be the surviving
corporation in the Merger (sometimes hereinafter referred to as the "Surviving
Corporation") and will continue to be governed by the laws of the State of
California, and the separate corporate existence of ASCOR with all its rights,
privileges, immunities, powers and franchises will continue unaffected by the
Merger, except as set forth in the Reorganization Agreement. The Merger will
have the effects specified in California Corporate Law.

     As soon as practicable following the closing of the Merger, and provided
that the Reorganization Agreement has not been terminated or abandoned, ASCOR
and Acquisition Corp. will cause the Agreement of Merger to be executed,
acknowledged and filed with the Secretary of State of the State of California.
The Merger will become effective at such time as the Agreement of Merger (the
form of which is attached as Exhibit 1.01 to the Reorganization Agreement) has
been duly filed with the Secretary of State of the State of California.

     The Exchange Ratio. At the Effective Time, by virtue of the Merger and
without any action on the part of the holder of any ASCOR Securities, (i) each
(a) share of ASCOR Common Stock and ASCOR Preferred Stock outstanding
immediately prior to the Merger (other than ASCOR Shares held by shareholders
who have perfected and not withdrawn their right to seek appraisal of their
shares under applicable California law) and (b) outstanding ASCOR Convertible
Security will be converted into the right to receive a pro rata portion of the
Merger Consideration (a maximum aggregate of 724,986 Shares of Giga-tronics
Common Stock) and (ii) any ASCOR Convertible Securities which are considered
"out-of-the-money" will be assumed by Giga-tronics and will be exercisable for
Giga-tronics Common Stock as adjusted by the Merger. (See " - ASCOR Convertible
Securities.") In determining the Exchange Ratio of Giga-tronics Common Stock for
ASCOR Securities which holders of ASCOR Shares and ASCOR Convertible Securities
will be entitled to receive, all ASCOR Convertible Securities will be treated as
having been converted or exercised into ASCOR Shares. Shares of Giga-tronics
Common Stock attributable to ASCOR Convertible Securities which are assumed by
Giga-tronics will be retained by Giga-tronics from the Merger Consideration
pending their exercise.

     A maximum of 724,986 shares of Giga-tronics Common Stock will be issuable
in the Merger, including (a) shares issuable in respect of ASCOR Convertible
Securities which are assumed, which shares will be retained by Giga-tronics if
such securities expire unexercised, (b) fractional shares, (c) shares issuable
in respect of ASCOR Shares for which dissenters' appraisal rights (see "THE
MERGER - Dissenters' Appraisal Rights") are perfected, and (d) shares deemed
surrendered upon exercise of ASCOR Convertible Securities for which a deemed net
exercise has occurred.

     The Agreement of Merger to be filed will contain the final exchange ratio
(the "Exchange Ratio") for ASCOR Shares into Giga-tronics Common Stock which
will be equal to 724,986


                                      -43-
<PAGE>   51
divided by the fully diluted number of ASCOR Shares outstanding at the Effective
Time (the "ASCOR Outstanding Equivalent Number"). The ASCOR Outstanding
Equivalent Number will be equal to the sum of (1) the number of ASCOR Shares
outstanding at the Effective Time; plus (2) the total number of ASCOR Shares
which would be issuable on the exercise of any ASCOR Convertible Securities. All
ASCOR Shares will be exchangeable into Giga-tronics Common Stock at the same
Exchange Ratio.

     ASCOR Convertible Securities. Except as discussed below Giga-tronics will
not assume any ASCOR Convertible Securities. At the Effective Time, outstanding
ASCOR Convertible Securities will be deemed exercised for such number of shares
of Giga-tronics Common Stock as would be exchanged in the Merger for the ASCOR
Shares which would have been issued had such ASCOR Convertible Securities been
exercised in full immediately prior to the Effective Time, subject to the
following provisions. Such deemed exercise of ASCOR Convertible Securities will
be on a "net exercise" basis. The full number of shares issuable on exercise of
such ASCOR Convertible Securities (including such number of shares as are deemed
surrendered in the net exercise) will be included in the number of ASCOR Shares
used in calculating the Exchange Ratio. The value of the ASCOR Shares issuable
on the exercise of any ASCOR Convertible Security for purposes of determining
the number of ASCOR Shares to be surrendered in the deemed net exercise shall be
equal to the number of ASCOR Shares issuable on exercise of such ASCOR
Convertible Security, multiplied by the Exchange Ratio, multiplied by the
average closing price of a share of Giga-tronics Stock on such stock exchange as
Giga-tronics Stock is then traded for the five (5) business days immediately
preceding the Closing Date. Shares of Giga-tronics Common Stock which would
otherwise be issuable in respect of the ASCOR Shares deemed surrendered upon
such net exercise will be retained by Giga-tronics and not otherwise issued.

      Notwithstanding the foregoing, any ASCOR Warrant which, based upon the
foregoing determination of the value of ASCOR Shares issuable on its exercise,
would be "out-of-the-money" will be assumed by Giga-tronics. For purpose of the
forgoing determination, an ASCOR Warrant will be deemed out-of-money if its
exercise price per share is greater than the value of such share as determined
as described in the immediately preceding paragraph. Any assumed ASCOR Warrant
will remain outstanding and exercisable in accordance with its terms except that
(1) it will be exercisable for such number of shares of Giga-tronics Common
Stock as equals the number of ASCOR Shares for which it was exercisable
multiplied by the Exchange Ratio and (2) the exercise price per share of such
warrant will be the exercise price as stated on such warrant divided by the
Exchange Ratio. The number of shares of Giga-tronics Common Stock as would be
issuable on exercise of any ASCOR Warrants so assumed will be reserved out of
the Merger Consideration. If any ASCOR Warrant assumed by Giga-tronics expires
unexercised the Giga-tronics Common Stock which would have been issuable on its
exercise will be retained by Giga-tronics and not otherwise issued.

     Registration of Merger Consideration. As amended by the Letter Agreement
the Reorganization Agreement contemplates that Giga-tronics will use its best
faith efforts to secure the registration of the Giga-tronics Common Stock to be
issued pursuant to the Merger. As registered securities, such shares of
Giga-tronics Common Stock held by former shareholders of ASCOR who were not
affiliates of ASCOR or Giga-tronics will generally be freely tradable. If the
Giga-tronics Common Stock to be issued pursuant to the Merger are not so
registered, they will be issued pursuant to a transaction not involving a public
offering and therefore will be characterized as "restricted securities" under
federal securities laws. Pursuant to the Securities Act of 1933, as amended (the
"Securities Act") any Giga-tronics Common Stock so issued may be resold without
registration under the Securities Act only in certain limited circumstances. The
Certificates issued pursuant to the Merger without registration would bear the
following legend relating to their status as restricted securities:


                                      -44-
<PAGE>   52
               "These securities have not been registered under the Securities
               Act of 1993, as amended. They may not be sold, offered for sale,
               pledged or hypothecated in the absence of a registration
               statement in effect with respect to the securities under such Act
               or an opinion of counsel satisfactory to the Company that such
               registration is not required or unless sold pursuant to Rule 144
               of such Act."

     Other than as provided by the Letter Agreement if the Giga-tronics Common
Stock issued in the Merger is not registered, Giga-tronics will be under no
obligation to effect a registration statement with respect to Giga-tronics
Common Stock issued in the Merger other than as required pursuant to the
Registration Rights Agreement.

     If such stock is issued pursuant to an effective registration statement,
the Registration Rights Agreement will be of no force and the Giga-tronics stock
issued will not be legended as above. See " - Registration Rights Agreement" and
"Letter Agreement."

     Exchange of Certificates. Prior to the Effective Time, Giga-tronics shall
appoint a bank or trust company to act as exchange agent (the "Exchange Agent")
in the Merger.

     As soon as practicable after the Effective Date, the Exchange Agent will
mail to each holder of record of a stock certificate that, immediately prior to
the Effective Time, represented outstanding of ASCOR Shares (a "Certificate")
whose shares are being converted into Giga-tronics Common Stock (i) a letter of
transmittal, and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for certificates evidencing Giga-tronics Common Stock.
Upon surrender of a Certificate for cancellation to the Exchange Agent, together
with such letter of transmittal, duly executed, the holder of such Certificate
will be entitled to receive in exchange therefor a certificate for the number of
whole shares of Giga-tronics Common Stock to which the holder of such ASCOR
Shares is entitled pursuant to the Reorganization Agreement (and an amount of
cash in lieu of any fractional shares of Giga-tronics Common Stock as discussed
below). The Certificate so surrendered will forthwith be canceled. Until
surrendered, each Certificate will be deemed at any time after the Effective
Time to represent the right to receive upon such surrender such whole number of
shares of Giga-tronics Common Stock as provided by the Reorganization Agreement
and an amount of cash in lieu of any fractional shares of Giga-tronics Common
Stock as discussed below.

     The Exchange Procedures for ASCOR Preferred Stock will differ from the
foregoing as described below.

     It is a condition for Giga-tronics' obligation to consummate the Merger
that all ASCOR Preferred Stock be tendered at the closing for exchange for
Giga-tronics Common Stock. See " - Conditions to the Merger." The ASCOR
Preferred Stock so tendered must be accompanied by the Tender Instructions, in
the Form of Annex I, pursuant to which the holder of ASCOR Preferred Stock will
agree to accept Giga-tronics Common Stock at the exchange ratio described above
and waive any rights to different or additional consideration to which they may
be entitled in a transaction such as the Merger. Such rights to additional
consideration may arise due to accrual of dividends on the ASCOR Preferred
Stock, exercise of liquidation preference rights or conversion of the ASCOR
Preferred Stock into ASCOR Common Stock prior to the Merger. See "DESCRIPTION OF
GIGA-TRONICS" AND ASCOR SECURITIES - ASCOR - ASCOR PREFERRED STOCK."

     No dividends on the Giga-tronics Common Stock to be issued in the Merger
will be paid to the holder of any unsurrendered Certificate until the holder of
record of such Certificate will surrender such Certificate; provided, however,
that upon surrender of a Certificate which immediately prior to the Effective
Time represented shares of ASCOR Common Stock, there will be paid to the


                                      -45-
<PAGE>   53
holder of such Certificate the amount of dividends, if any, without interest,
which theretofore became payable, but which were not paid by reason of the
foregoing, with respect to the number of whole shares of Giga-tronics Common
Stock represented by the Certificate or Certificates issued upon such surrender.
Subject to the effect, if any, of applicable escheat and other laws, following
surrender of any Certificate, there will be delivered to the person entitled
thereto, without interest,the amount of dividends so withheld as of any date
subsequent to the Effective Time of the Merger and prior to such date of
delivery.

     All Giga-tronics Common Stock delivered, and cash in lieu of any fractional
shares of Giga-tronics Common Stock paid, upon the surrender for exchange of
shares of ASCOR Common Stock will be deemed to have been delivered and paid in
full satisfaction of all rights pertaining to such shares. If, after the
Effective Time, Certificates are presented for any reason, they will be canceled
and exchanged pursuant to the Reorganization Agreement.

     No fractional shares of Giga-tronics Common Stock will be issued in
connection with the Merger. All shares of Giga-tronics Common Stock to which a
holder of ASCOR Shares is entitled immediately prior to the Effective Time will
be aggregated. If a fractional share results from such aggregation, in lieu of
any such fractional share, each holder of ASCOR Shares who would otherwise have
been entitled to receive a fraction of a share of Giga-tronics Common Stock upon
surrender of Certificates for exchange will be entitled to receive from the
Exchange Agent a cash payment equal to such fraction multiplied by the closing
sale price per share of Giga-tronics Common Stock on the last business day on
which Giga-tronics Common Stock is traded on the NASD prior to the Effective
Time.

Merger; (i) keep confidential for a period of three years following the
termination of the Reorganization Agreement confidential information of each

     No Solicitation of Transactions. Pursuant to the Reorganization Agreement,
from the date of the Reorganization Agreement until the earlier of the Effective
Time of the Merger or termination of the Reorganization Agreement, ASCOR and the
officers, directors, employees or other agents of ASCOR have agreed they will
not, directly or indirectly, (i) take any action to solicit, initiate or
encourage the making of any Acquisition Proposal (as hereinafter defined); or
(ii) engage in negotiations with, or disclose any nonpublic information relating
to ASCOR or afford access to the properties, books or records of ASCOR to, any
person or entity that informs the Board of Directors that it is considering
making, or has made, an Acquisition Proposal. Until such time as the
Reorganization Agreement is terminated in accordance with its terms, ASCOR has
agreed not to enter into any agreement to merge or consolidate with, or sell a
substantial portion of its assets to, any person or entity. ASCOR has agreed to
promptly notify Giga-tronics after receipt of any Acquisition Proposal or any
request for nonpublic information relating to ASCOR in connection with an
Acquisition Proposal or for access to the properties, books or records of ASCOR
by any person or entity that informs the Board of Directors that it is
considering making, or has made, an Acquisition Proposal. The term "Acquisition
Proposal" means (i) any merger, consolidation, tender offer or other similar
transaction or related transactions pursuant to which the holders of the voting
securities of ASCOR prior to the transaction hold following the consummation of
such transaction less than 80% of the voting securities of the surviving entity,
(ii) a sale of a material portion of the assets of ASCOR, or (iii) any equity or

securities of ASCOR representing more than 20% of the aggregate voting power of
ASCOR's outstanding securities, other than in each case the transactions
contemplated by the Reorganization Agreement or such transactions as occur via
unsolicited purchases in the open market. For purposes of the foregoing
definition, one person is deemed to be affiliated with a


                                      -47-
<PAGE>   55
second person if such first person controls, is controlled by or is under common
control with the second person, and control, for purposes hereof, is deemed to
exist only in the event there exists ownership of or the right to vote, in
either case directly or indirectly, securities representing more than 50% of the
aggregate voting power of an entity's outstanding securities.

     Conditions to the Merger. The respective obligations of ASCOR, Giga-tronics
and Acquisition Corp. to consummate the Merger are subject to the fulfillment of
each of the following conditions, among others: (a) the accuracy of warranties
and representations; (b) covenants shall have been complied with in all material
respects on or before the Effective Time and a Certificate of a respective
officer of Giga-tronics and ASCOR as the case may be, shall have been received
by the other party; (c) there shall have been no Material Adverse Effect (as
defined in the Reorganization Agreement) and no material adverse change; (d)
Giga-tronics shall have received executed Affiliate Agreements; (e) the
shareholders of ASCOR and Giga-tronics shall have approved and adopted the
Reorganization Agreement and the transactions contemplated thereby; (f)
Giga-tronics and ASCOR shall have received a written opinion from Brobeck that
the Merger will constitute a reorganization within the meaning of Section 368 of
the Code; (g) no statute, rule or regulation by any court or governmental
authority shall prohibit the consummation of the Merger; (h) all written
consents or authorizations that are required shall have been obtained; and (i)
Giga-tronics shall have completed a due diligence review of ASCOR and such
review shall not have revealed any facts or circumstances which could have a
material adverse effect on ASCOR; and (j) it is a condition of Giga-tronics'
obligations that Giga-tronics' shareholders shall not have perfected Dissenters'
Rights with respect to 5% or more of the Giga-tronics Common Stock outstanding
on the date of the Special Meeting.

     It is a condition of Giga-tronics obligations under the Reorganization
Agreement that as of the Closing Date all shares of ASCOR Preferred Stock
outstanding as of the date the Reorganization Agreement was executed shall (i)
have remained outstanding, (ii) shall have been tendered at the Closing with the
Tender Instructions which provides that such shares are to be exchanged at the
Effective Time for Giga-tronics Common Stock in accordance with the terms of the
Reorganization agreement, and (iii) not have been transferred by the owners of
such shares as of the date of the Reorganization Agreement to any other person.

     The Reorganization Agreement further provides that it is a condition of
Giga-tronics obligations to consummate the Merger that in Giga-tronics' sole
discretion the Merger qualifies for accounting treatment as a pooling of
interests in accordance with Accounting Principles Board Release No. 16. In
making the determination of whether the Merger so qualifies Giga-tronics may
consider the impact of ASCOR Shares which are voted against the Merger or which
have abstained from voting with respect to the Merger.

     Termination. The Reorganization Agreement may be terminated and the Merger
may be abandoned at any time prior to the Effective Time, before or after the
approval by the ASCOR shareholders: (a) by the mutual consent of the ASCOR,
Giga-tronics and Acquisition Corp. Board of Directors; (b) by Giga-tronics and
Acquisition Corp. or by ASCOR if the Reorganization Agreement is not approved
and adopted by Giga-tronics and ASCOR's shareholders prior to December 31, 1996;
(c) by the parties to the Reorganization Agreement if there has been a breach of
any representation and warranty, or a breach of any covenant or agreement
contained in the Reorganization Agreement that has not been cured or waived and
which has a material adverse effect on the breaching party; (d) by the parties
to the Reorganization Agreement at any time after December 31, 1996, unless the
delay is caused by the failure of the terminating party to fulfill its
obligations; (e) by Giga-tronics or Acquisition Corp. if such party is not in
material breach of its obligations and if the Board of Directors of ASCOR
withdraws its recommendation of the Merger or recommends, or approves,
acceptance by ASCOR shareholders of any Acquisition Proposal by any other party;
(f) by ASCOR, if it is not in material breach of its obligations and if the
Board of Directors of either Giga-tronics or Acquisition Corp. withdraw its
recommendation of the Merger,

                                      -48-
<PAGE>   56
or recommend or approve acceptance by Giga-tronics shareholders of any
Acquisition Proposal by any other party; (g) by Giga-tronics if the conditions
described above regarding absence of pooling-of-interest issues and perfection
of dissenters' rights by Giga-tronics' shareholders with respect to dissenters'
rights are not fulfilled; and (h) by Giga-tronics if ASCOR has issued any ASCOR
Securities between the date of the Reorganization Agreement and the Closing Date
without Giga-tronics' prior consent.

     Governance. The Certificate of Incorporation and Bylaws of Acquisition
Corp. in effect immediately prior to the Effective Time will be the Certificate
of Incorporation and Bylaws of the Surviving Corporation. At the Effective Time,
the initial directors of the Surviving Corporation and the officers of ASCOR
will become the initial directors and officers, respectively of the Surviving
Corporation.

     Expenses. Whether or not the Merger is consummated, each party will pay all
fees and expenses incurred by such party specifically identifiable to such party
in connection with the transactions contemplated thereby. Any other costs and
expenses not specifically identified as applicable to either party will be
shared equally.

     Amendment and Waiver. Subject to the applicable provisions of California
law, the parties may modify or amend the Reorganization Agreement by written
agreement at any time prior to the Effective Time. The conditions to each
party's obligations to consummate the Merger may be waived by such party in
whole or in part to the extent permitted by applicable law.

LETTER AGREEMENT

     Pursuant to the Letter Agreement between Giga-tronics and ASCOR dated May
20, 1996 (attached as Annex J) Giga-tronics has agreed to use its best faith
efforts to file with the Securities and Exchange Commission, and cause the
effectiveness under federal securities law of, a registration statement on Form
S-4 (or such other form as may be applicable) covering the shares of
Giga-tronics Common Stock to be issued in the Merger. ASCOR agreed that upon the
issuance of such Giga-tronics Common Stock pursuant to an effective registration
statement the Registration Rights Agreement would be of no force and effect and
would therefore not be delivered at the Closing.

REGISTRATION RIGHTS AGREEMENT

     Pursuant to the Reorganization Agreement, Giga-tronics will enter into the
Registration Rights Agreement at the Effective Time with ASCOR Shareholders. The
following is a summary of the Registration Rights Agreement. This summary is
qualified in its entirety by reference to the complete text of such agreement, a
form of which is filed as an exhibit to the Registration Rights Agreement.

     If at any time after results covering at least thirty (30) days of combined
operations of the Company and ASCOR have been published by the Company in the
form of a quarterly earnings report, an effective registration statement filed
with the Securities and Exchange Commission (the "Commission"), a report to the
Commission on Form 10-K, 10-Q or 8-K, or any other public filing or announcement
which includes the combined results of operation, "Holders" (as that term is
defined below) request in writing that Giga-tronics file a registration
statement under the Securities Act covering the registration of at least 200,000
Registrable Securities (as such number may be adjusted from time to time for
stock dividends, splits or other changes in the capitalization of Giga-tronics)
or a lesser number if the anticipated aggregate offering price, net of
underwriting discounts and commissions, would exceed $1,000,000, then
Giga-tronics will, subject to certain provisos, use all reasonable efforts to
file and cause the effectiveness of, within 90 days of the


                                      -49-
<PAGE>   57
receipt of such request, the registration under the Securities Act of all
Registrable Securities which the Holders request to be registered. Giga-tronics
will have the right to defer requested registrations in certain circumstances.

     Giga-tronics is obligated to effect only one (1) such registration pursuant
to the Registration Rights Agreement. Giga-tronics will be obligated to maintain
the effectiveness of any registration statement filed pursuant to the Holders'
request for no more than 180 days subsequent to declaration of its effectiveness
by the Commission.

     If Giga-tronics proposes to register (including for this purpose a
registration effected by the Company for shareholders other than the Holders)
any of Giga-tronics Common Stock or other securities under the Securities Act in
connection with the public offering of such securities solely for cash (other
than a registration relating either to the sale of securities to participants in
a Giga-tronics stock option, stock purchase or similar plan or to an SEC Rule
145 transaction, or a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities),
Giga-tronics will subject to certain provisos be required to cause to be
registered under the Securities Act all of the Registrable Securities that each
Holder requests be registered.

     All expenses other than underwriting discounts and commissions incurred in
connection with registrations, filings or qualifications, including (without
limitation), all registration, filing and qualification fees, printers and
accounting fees, fees and disbursements of counsel for Giga-tronics and the
reasonable fees and disbursements of up to $25,000 for one (but only one)
counsel for the selling Holders will be borne by Giga-tronics.

     The registration rights of any Holder expire (a) if the Registrable
Securities were issued by Giga-tronics to the Holder pursuant to a registration
statement filed with the SEC or (b) at and after such time as such Holder holds
Registrable Securities equal to 1% or less of the outstanding stock of the
Company (calculated on an as-converted basis) and is able to dispose of all the
Registrable Securities held by such Holder under Rule 144 of the Securities Act
during any 90-day period.

     Under the Registration Rights Agreement "Registrable Securities" means (a)
the shares of Giga-tronics Common Stock issuable to the ASCOR Shareholders upon
consummation of the Merger and any other shares of Giga-tronics Common Stock
issued as (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued as) a dividend or other distribution with respect
to, or in exchange for or in replacement of, the Registrable Securities with
certain exclusions. "Holder" is defined as any person owning of record
Registrable Securities who acquired such Registrable Securities in a transaction
or series of transactions not involving any registered public offering.

     As amended by the Letter Agreement, the Reorganization Agreement
contemplates that if the Giga-tronics Common Stock to be issued in the merger
has been issued under federal securities law pursuant to an effective
registration statement on Form S-4 (or such other form as may be applicable),
that the Registration Rights Agreement would be of no force or effect (due to
such event triggering the termination of registration rights thereunder) and
that the Registration Rights Agreement would therefore not be delivered at the
Closing.

AFFILIATE AGREEMENTS

     The following is a brief summary of the terms of the Affiliate Agreements,
copies of which are attached as exhibits to the Reorganization Agreement which
is attached as Annex C to the Joint Proxy Statement/Prospectus. This summary is
qualified in its entirety by reference to the full text of the Affiliate
Agreements.

     Pursuant to the Reorganization Agreement, certain shareholders of ASCOR and
Giga-tronics have or will executed Affiliate Agreements. Each Affiliate
Agreement provides, among other things, the following representations,
warranties and covenants: (a) the party will not sell, transfer, exchange or
otherwise dispose of any shares of Giga-tronics Common Shares acquired in the
Merger unless such transaction is permitted under Rule 144 or Rule 145 under the
1933 Act or counsel representing the party shall have advised Giga-tronics that
no registration under the 1933 Act is required; and (b) the party has, and as of
the Effective Time will have, no plan or intention to sell, transfer, exchange
or otherwise dispose of more than fifty percent of the shares of Giga-tronics
Common Stock acquired in connection with the Merger. The Affiliate Agreement
will terminate upon the termination of the Reorganization Agreement.

                           COMPARATIVE PER SHARE DATA
   
     Set out below are income and book value per common share data of
Giga-tronics and ASCOR on both a historical and a pro forma condensed combined
basis and on a per share equivalent pro forma basis for ASCOR. Pro forma
condensed combined per share information is derived from the pro forma condensed
combined information presented elsewhere herein which gives effect to the Merger
under the pooling of interests accounting method at the beginning of the
earliest period presented, and assumes the issuance of 724,986 shares of
Giga-tronics Common Stock in 1995 and 1994. Expenses directly attributable to
the consummation of the Merger are expected to approximate $250,000. The pro
forma adjustment to retained earnings is $125,000 while the total estimated
costs are $250,000 because $125,000 of costs are already included in the fiscal
1996 financial statements. The estimated $250,000 of merger costs are not
included in the pro forma statements of operations since they will be
nonrecurring. The expenses have been deducted in calculating the pro forma
combined book value per share, but are not reflected in the pro forma earnings
(loss) per share amounts. Neither Giga-tronics or ASCOR has paid any dividends
on its capital stock during the periods presented.

     The pro forma information is presented for illustrative purposes only and
is not necessarily indicative of the operating results or financial position
that would have occurred if the Merger had been consummated, nor is it
necessarily indicative of future operating results or financial position.

March 26, 1994 with the results of ASCOR for twelve months ended March 31, 1996,
March 31, 1995, and March 31, 1994. Pro forma combined per share data gives
effect to the assumed issuance of 724,986 shares of Giga-tronics Common Stock in
exchange for the ASCOR Common Stock in the Merger.

     The pro forma financial information is presented for illustrative purposes
only and is not necessarily indicative of the operating results or financial
position that would have occurred if the Merger had been consummated, nor is it
necessarily indicative of future operating results or financial position.

     The pro forma condensed combined financial information set forth below
gives effect to the Merger under the pooling of interests accounting method at
the beginning of the earliest period presented. The pro forma condensed combined
statements of operations assume the issuance of 724,986 shares of Giga-tronics
Common Stock in 1995 and 1994, and do not give effect to the estimated costs
associated with the consummation of the Merger. Total expenses directly
attributable to the consummation of the Merger are expected to approximate
$250,000. The pro forma condensed combined balance sheet reflects the $250,000
estimated costs of the Merger as a reduction of retained earnings.

                             INFORMATION CONCERNING
                            GIGA-TRONICS INCORPORATED

General and Business

         Giga-tronics designs, manufactures and markets microwave and radio
frequency (RF) signal generation and power measurement instruments. These
products are used primarily in the design, production, repair and maintenance of
telecommunications, radar, electronic warfare, and transportation systems.

Industry Segments

         Giga-tronics operates in one industry segment: electronic test and
measurement equipment.

Products and Markets

         Giga-tronics produces signal sources, generators and sweepers, and
power measurement instruments for use in the microwave and RF frequency range
(10 Khz to 75 GHz). Within each product line are a number of different models
and options allowing customers to select frequency range and specialized
capabilities, features and functions.

         The end-user markets can be divided into three broad segments:
telecommunications, radar and electronic warfare. Giga-tronics' instruments are
used in the design, production, repair and maintenance and calibration of other
manufacturers' products, from discrete components to complex systems.

Sources and Availability of Raw Materials and Components

         Substantially all of the components required by Giga-tronics to make
its assemblies are available from more than one source. Giga-tronics
occasionally uses sole source arrangements to obtain leading-edge technology,
favorable pricing or supply terms. Although extended delays in delivering
components could result in longer product delivery schedules, Giga-tronics
believes that its protection against this possibility stems from its practice of
dealing with well-established suppliers and maintaining good relationships with
such suppliers.

Patents and Licenses

         Giga-tronics attempts to obtain patents when appropriate. In addition,
Giga-tronics has acquired numerous patents in the course of its two recent
acquisitions. However, Giga-tronics believes that its competitive position
depends on the creative ability and technical competence of its personnel and
the timely introduction of new products rather than on the ownership or
development of patents.

         Giga-tronics licenses certain instrument operating system software from
third parties. Other than such software licenses, Giga-tronics is not aware that
the manufacture and sale of its products requires licenses from others.
Giga-tronics believes, based on industry practice, that any necessary licenses
could be obtained on conditions which would not have a materially adverse
financial effect on Giga-tronics.

Seasonal Nature of Business

         The business of Giga-tronics is not seasonal.

Working Capital Practices

         Giga-tronics does not believe that it has any special practices or
special conditions affecting working capital items that are significant for an
understanding of its business.

Importance of Limited Number of Customers

         Since its inception, Giga-tronics has been a leading supplier of test
instruments to various U.S. Government defense agencies, as well as to their
prime contractors. U.S. Government agencies accounted for 31%, 26%, and 27% of
net sales in fiscal 1996, 1995, and 1994, respectively. Management anticipates
sales to U.S. Government agencies will remain significant in fiscal 1997, even
though the outlook for defense-related orders continues to be soft.

Backlog of Orders

         On March 30, 1996, Giga-tronics had a backlog of approximately
$6,112,000 compared to $10,154,000 at March 25, 1995. Orders for Giga-tronics'
products include large program orders, from both the U.S. Government and defense
contractors, with extended delivery dates. Accordingly, the backlog of orders
may vary substantially from quarter to quarter and the backlog entering any
single quarter may not necessarily be indicative of sales for any period.

         Backlog includes only those customer orders for which a delivery
schedule has been agreed upon between Giga-tronics and the customer and, in the
case of U.S. Government orders, for which funding has been appropriated.
Giga-tronics believes that essentially all of the year ending backlog will be
shipped within the next twelve months.

         A substantial portion of the year-end backlog consisted of U.S.
Government contracts. These contracts contain customary provisions permitting
termination at the convenience of the Government upon payment of a negotiated
cancellation charge. Giga-tronics never has experienced a significant contract
termination.

Competition

         The principal competitive factors in the marketing of microwave and RF
test instruments include product functionality, reliability and price.
Giga-tronics competes mainly with Hewlett-Packard, Anritsu, Marconi and Rohde &
Schwarz. These competitors are larger and have greater financial, engineering
and marketing resources than the Company. Nonetheless, Giga-tronics believes
that within its chosen markets and applications, its products are fully
competitive with those of other manufacturers.

Product Development

         Microwave and RF test instruments of the type manufactured by
Giga-tronics historically have had relatively long product life cycles. However,
the electronics industry is subject to rapid technological changes at the
component level. The future success of Giga-tronics is dependent on its ability
to steadily incorporate advancements in semiconductor and related microwave
component technologies into its new products.

         Product development expense was approximately $2,512,000, $2,700,000
and $2,569,000 in fiscal 1996, 1995 and 1994, respectively. Activities included
the development of

                                      -61-
<PAGE>   69
new products and the improvement of existing products. It is management's
intention to maintain expenditures for product development at levels required to
sustain its competitive position. All of Giga-tronics' product development
activities are internally funded and expensed as incurred.

Manufacturing

         The assembly and testing of Giga-tronics' microwave, RF and power
measurement products is done at its relatively new San Ramon facility. The
Sunnyvale manufacturing operations (performing assembly and test of power
measurement products) relocated to the San Ramon facility in July, 1995.

Environment

         To the best of its knowledge, Giga-tronics is in compliance with all
federal, state and local laws and regulations involving the protection of the
environment.

Employees

         As of March 30, 1996, Giga-tronics employed 146 persons. Management
believes that the future success of Giga-tronics depends on its ability to
attract and retain skilled personnel. None of Giga-tronics' employees is
represented by a labor union and Giga-tronics considers its employee relations
to be excellent.

Information about Foreign Operations

         Giga-tronics sells to its international customers through a network of
foreign technical sales representative organizations. Sales to foreign customers
were approximately $6,791,000, $4,458,000, and $4,544,000 in fiscal 1996, 1995
and 1994, respectively.

         Giga-tronics has no foreign-based operations or material amount of
identifiable assets in foreign countries. Its gross margins on foreign and
domestic sales are similar. Management does not believe that foreign sales are
subject to materially greater risks than domestic sales.

Outlook

         Even though Giga-tronics has now achieved more balance between its
defense and commercial businesses, defense related orders remain very important
to Giga-tronics. The outlook for such orders continues to be soft. Giga-tronics
believes that some growth can be realized by sustaining an effective new product
development program, aggressively pursuing new markets, vigorously competing for
defense business, and making synergistic acquisitions.

Property

         As of March 30, 1996, Giga-tronics' executive, marketing, sales and
engineering offices and manufacturing facilities are located in approximately
47,000 square feet in San Ramon, California, which Giga-tronics occupies under a
lease agreement expiring December 31, 2006. The 30,000 square foot facility in
Pleasant Hill, California, which formerly housed all of the signal generator
operations, was vacated at the end of April, 1994. The Pleasant Hill lease
agreement expired April 30, 1994. The 40,000 square foot facility in Sunnyvale,
California, which formerly housed all of the power measurement instrument
operations, was vacated in July, 1994. The Sunnyvale lease agreement expired
July 31, 1994.

Legal Proceedings

         As of March 30, 1996, Giga-tronics has no pending legal proceedings,
other than routine litigation incidental to the Company's business, to which
Giga-tronics is a party or to which any of its property is subject.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF GIGA-TRONICS FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS
                           FOR FISCAL 1996, 1995, 1994

       New orders received in 1996 were $20,856,000, a decrease of 21% from
1995, which increased 30% over 1994. In 1996, the decrease reflects large order
decreases in both the microwave signal generator (SG) and radio frequency signal
generator (RF) product line. In 1995, the increase in orders resulted from
additional orders in both the microwave signal generator and RF product line.
Overall, the approximate proportion of net sales coming from defense-related
customers was 31% in 1996 and less than 30% in 1995 and 1994. Continuing the
focus of a business better balanced between commercial and defense markets has
been and remains a major strategic priority. At year-end 1996, Giga-tronics'
backlog of unfilled orders was $6,112,000, compared to $10,154,000 at the end of
1995 and $5,800,000 at the end of 1994. The decrease in backlog from 1995 to
1996 resulted mostly from a decline in SG product line defense-related orders.
Due to the softness in order intake, fiscal 1997 revenues excluding ASCOR will
likely be less than fiscal 1996. However, it is projected at this time that
continued improvement in manufacturing efficiencies and other cost reduction
activities will largely offset any unfavorable impact caused by the decline in
revenues.
 

       Net sales for 1996 were $24,898,000, a 13% increase from 1995, which
follows a 10% increase in 1995 from 1994. Somewhat greater sales volume for SG
products was the major factor. Average selling prices were stable. Gross profit
as a percentage of sales increased to 37% in 1996, from 32% in 1995, due to
better factory efficiencies. Gross profit as a percentage of sales decreased
from 40% to 32% from 1994 to 1995 due to factory inefficiencies associated with
the acquired RF signal generator product lines, manufacturing scaleup of new
microwave products, inventory reserve increases related to the above product
lines, and certain costs for upgrading Giga-tronics' management information
system. Giga-tronics continues to implement programs to improve manufacturing
efficiencies and reduce costs.

       While there is a small percentage of product lines (less than 10% of
sales) with poor profit margins due to aging of product, potential inventory
obsolescence has been carefully analyzed and fully reserved for. There is no
expected impact on future results of operations for these product lines. More
over, there is a plan for designing and bringing to market new products, which
will replace products reaching the end of their life cycle. Since potential
inventory obsolescence is constantly being scrutinized, and new product launches
are being planned for fiscal 1997 and fiscal 1998, future results of operations
are not expected to deteriorate due to these factors.
    

       Operating expenses decreased 9% in 1996 over 1995. Costs were tightly
controlled in many areas despite higher sales. In 1995, operating expenses
increased 17% from 1994 due to personnel severance costs (including those
associated with the resignation of Mr. Donald F. Bogue as President and Chief
Executive Officer) and additional inventory reserves taken for customer
demonstration equipment utilized by sales and marketing.

       Amortization expense, relating to the intellectual property and
non-compete convenants associated with two prior acquisitions, amounted to
$560,000, the same as 1995 and increasing from $410,000 in fiscal 1994. The
increase from 1994 to 1995 is due to 1995 being the first fiscal year with the
full 12 month effect of the two acquisitions (the RF product line in fiscal 1994
and the power measurement product line in fiscal 1993).

       Interest income increased by 43% to $323,000 in 1996, following a
decrease of 28% from 1994 to 1995. The increase in 1996 interest income from
1995 was due primarily to an increase in cash, resulting from an earnings
increase and much lower inventory levels. The decrease in 1995 was due to the
earnings decline in 1995 and higher inventory balances in fiscal 1995 relative
to the inventory level in fiscal 1994. Giga-tronics continues to invest
principally in securities which are exempt from federal taxes.

       The provision for income taxes in 1996 was $301,000. In 1995, income tax
expense was a benefit due to a pretax loss of approximately $2,220,000.

   
       Giga-tronics recorded net earnings of $901,000, or $0.34 per share, in
1996, an increase in earnings per share from a $0.61 loss in 1995, and $0.09
earnings per share in 1994. The improved results in 1996 were due to a sales
increase of 13%, an improved gross profit margin, a decrease in operating
expenses of 9%, and an increase in interest income. The loss in 1995 was largely
a result of delayed product shipments, depressed manufacturing margins in
certain microwave and RF signal generator product lines, related inventory
reserve increases, personnel severance costs, and certain costs for upgrading
Giga-tronics' management information system, all of which are not expected 
to recur.

Financial Condition and Liquidity

   
     At year-end 1996, Giga-tronics had $10,785,000 in cash, cash equivalents 
and investments, compared to $5,768,000 at the beginning of the year. Most of 
the increase resulted from the higher earnings, lower inventories and lower 
receivables in 1996. Inventories have decreased $2 million ($2M) in 1996 due 
largely to the completed implementation of the MIS system installed early in 
fiscal 1995. It took almost two years to successfully install and effectively 
use all of the MIS management tools. Production management now procures 
inventory closer to shipment time. The receivables declined by $800,000 in 1996
due to a $200,000 increase in the allowance for doubtful accounts and a 
$600,000 decrease in gross receivables. The allowance has been increased due to
the substantial relative increase in "risky" (potentially uncollectible) sales 
recorded in fiscal 1996 compared to fiscal 1995. The gross receivables have 
decreased due to more effective collection efforts on the part of Giga-tronics. 
Cash provided from operations amounted to $5,161,000 in 1996, compared to cash 
provided from operations of $158,000 in 1995, and cash used by operations of
$932,000 in 1994. In 1995, cash provided by operations was negligible, as the 
small favorable change in balance sheet accounts and "the depreciation 
add-back" was mostly offset by a $1.6M loss. In 1994, a $2.1M increase in
inventories was the major factor in the negative cash flow from operations. 
This increase was due to a deteriorating MIS system (replaced in early fiscal 
1995) and the acquisition of two Fluke Company product lines and related 
inventory in June of 1993.
    

       Giga-tronics continues to maintain a strong financial position, with
working capital at year-end of $15,830,000, compared to $13,242,000 and
$14,209,000 at the end of 1995 and 1994, respectively. Giga-tronics' current
ratio of 5.3 increased somewhat from the 1995 and 1994 figures.
   

       Additions to property and equipment were $356,000 in 1996, compared to
$670,000 and $673,000 in 1995 and 1994, respectively. This spending reflects
continuing investments to support new product development, increase productivity
and improve product quality. Other cash outflows for investing activities
included $1.3M in 1996 and $3.7M in 1994 for purchases of short-term
investments. These are marketable securities, which are available for sale on
short notice. In 1994, there was a $1.1M outflow for the acquisition of two
product lines from the Fluke Company. Financing cash inflow in 1996 was due to
exercise of stock options.
    

         Management believes that Giga-tronics has adequate resources to meet
its operating and capital expenditure needs for the foreseeable future.

                             INFORMATION CONCERNING
                                   ASCOR, INC.

General and Business

         ASCOR was founded and incorporated in California in 1987. ASCOR
designs, manufacturers and markets high frequency and high density switches.
These switches are used in support of Automated Test Equipment (ATE) or any
other application where VXI bus (VME extensions for Instrumentation)
architecture is utilized.

Industry Segments

         ASCOR operates in one industry segment: electronic test and measurement
equipment.

Products and Markets

         ASCOR produces switch modules which meet the need for low noise and
high density switching within the VXI chassis. Switch matrices and scanners
utilize over 1,600 relays in a single VXI bus module. Additionally, ASCOR offers
switch modules that operate with a bandwidth from DC to in excess of 18
Gigahertz. ASCOR also offers Interface Adapters, which allow multiple pieces of
equipment to be tested using the same test instruments. Within the product line,
there are a number of different modules and options allowing customers to select
frequency range and specialized capabilities, features and functions.

         The end-user markets are primarily related to electronic warfare,
though there will likely be an increasing demand from the telecommunications
market if the VXI bus architecture becomes more readily accepted.

Sources and Availability of Raw Materials and Components

         Substantially all of the components required by ASCOR to make its
assemblies are available from more than one source. ASCOR occasionally uses sole
source arrangements to obtain leading-edge technology, favorable pricing or
supply terms. Although extended delays in delivering components could results in
longer product delivery schedules, ASCOR believes that its protection against
this possibility stem from its practice of dealing with well-established
suppliers and maintaining good relationships with such suppliers.

Patents and Licenses

         ASCOR has an exclusive arrangement with GDE Systems for the use and
manufacture of a high speed digital pin driver and receiver device. This is a
high density semiconductor device used for the output stage of a digital test
system. This device contains all the circuitry to drive, receive, or load
digital circuits that is being tested. It has an advantage in that it is
packaged in one silicon chip and saves circuit board space. The device will give
ASCOR the advantage of designing more complex digital VXI modules than possible
with current techniques used by competitors.

Seasonal Nature of Business

         The business of ASCOR is not seasonal in nature.


                                      -66-
<PAGE>   74
Working Capital Practices

         ASCOR does not believe that it has any special practices or special
conditions affecting working capital items that are significant for an
understanding of its business. It can be noted, moreover, that most inventory is
procured on the basis of confirmed customer sales orders.

Importance of Limited Number of Customers

         Since its inception, ASCOR has been a leading supplier of test
instruments to various defense-related contractors. Defense-related orders
accounted for 87%, 87%, and 100% of net sales in the twelve-month periods ending
March, 1996, March, 1995, and March, 1994. Management anticipates sales to
defense contractors will remain significant in fiscal 1997.

Backlog of Orders

         On March 30, 1996, ASCOR had a backlog of approximately $2,742,000
compared to $3,023,000 on March 25, 1995. Orders for ASCOR included large
program orders, from both commercial and defense contractors.

         Backlog includes only those customer orders for which a delivery
schedule has been agreed upon between ASCOR and the customer, and in the case of
defense-related orders, for which funding has been appropriated. ASCOR believes
that essentially all of the March period end backlog will be shipped within the
next twelve months.

         A majority of the March 30, 1996 backlog is related to defense-related
contracts. These contracts contain customary provisions permitting termination
at the convenience of the customer upon payment of a negotiated cancellation
charge. ASCOR never has experienced a significant contract termination.

Competition

         The principal competitive factors in the marketing of VXI switching
interface adapters include product modularity, density factor, quality, and
price. ASCOR competes mainly with Racal Dana, Hewlett Packard and Tektronix.
These competitors are larger and have greater financial, engineering and market
resources than ASCOR. However, ASCOR's product line has superior performance
over equivalent competitors' models. In addition, the modular design approach of
ASCOR's product lends itself to more flexible configuration in order to meet the
needs of the customers. ASCOR's products are therefore technically superior to
those of other manufacturers while being competitive in price.

Product Development

         The electronics and communications industry is subject to rapid
technological changes at the component level. The future success of ASCOR is
dependent on its ability to steadily incorporate advancements in semiconductor
and related microwave component technologies into its new products.

         Product development expense was approximately $214,000, $228,000, and
$130,000 for the twelve month periods ending March, 1996, March 1995, and March
1994, respectively. Activities included the development of new products and the
improvement of existing products. It is management's' intention to maintain
expenditures for product development at levels required to sustain its
competitive position. All of ASCOR's recent product development activities are
internally funded. All product development costs are expensed as incurred.

Manufacturing

         The assembly and testing of ASCOR's products is done at its Fremont
facility. Manufacturing operations have been performed in this facility since
1987.

Environment

         To the best of its knowledge, ASCOR is in compliance with all federal,
state and local laws and regulations involving the protection of the
environment.

Employees

         As of March 30, 1996, ASCOR employed 48 persons. Management believes
that the future success of ASCOR depends on its ability to attract and retain
skilled personnel. None of ASCOR's employees is represented by a labor union and
ASCOR considers its employee relations to be excellent.

Information About Foreign Operations

         ASCOR has no formal organization for sales to international customers.
Currently, all of its products that ultimately are shipped overseas have been
sold to domestic prime contractors who have sold a complete automatic test
system overseas.

Outlook

         Since ASCOR focuses on system integration needs for low noise and high
density switching within the VXI chassis, growth would likely be realized on the
assumption that a growing number of instruments available in VXI bus
architecture would be demanded.

Property

         As of March 30, 1996, ASCOR's executive, marketing, sales and
engineering offices and manufacturing facilities are located in approximately
12,160 square feet in Fremont, California, which ASCOR occupies under a lease
expiring on January 31, 1998, including the exercise of three one-year options
to renew (original lease expired January 31, 1995).

Legal Proceedings

         As of March 30, 1996, ASCOR has no pending legal proceedings, other
than routine litigation incidental to ASCOR's business, to which ASCOR is a
party or to which any of its property is subject.

            MANAGEMENT'S DISCUSSION AND ANALYSIS OF ASCOR FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS
                           FOR FISCAL 1996, 1995, 1994

       New orders received in 1996 were $5,173,000, an increase of 190% from
1995, which decreased 78% over 1994. In 1996, the increase reflects an increase
in commercial related orders. In 1995, the decrease in orders resulted from a
reduction in defense related activity. Overall, the approximate proportion of
net sales coming from defense-related customers was 87% in 1996 and greater than
90% in 1995 and 1994. At year-end 1996, ASCOR's backlog of unfilled orders was
$2,356,000, compared to $3,023,000 at the end of 1995 and $5,223,000 at the end
of 1994. The decrease in backlog from 1995 to 1996 resulted mostly from an
increase in shipments against large orders placed in 1994.

       Net sales for 1996 were $5,913,000, a 47% increase from 1995, which
follows a 13% increase in 1995 from 1994. Gross profit as a percentage of sales
decreased to 37% in 1996, from 41% in 1995, due to lower margins earned on
commercial orders. Commercial sales are more price competitive, whereas
defense-related sales are typically sole source. In addition, the large
contract orders in 1995 allowed for greater manufacturing efficiencies and
lower material costs due to a higher volume of repetitive business. Gross
profit as a percentage of sales decreased from 45% to 41% from 1994 to 1995
due to increased material costs.
    

       Operating expenses increased 54% in 1996 over 1995. In an effort to
increase market share, additional marketing personnel were added and the use of
regional US sales reps were increased, causing an increase in sales commission
expense. In 1995, operating expenses increased 51% from 1994 due to the addition
of a Director of Sales & Marketing, a Controller and an increase in national
advertising.

       Interest expense in 1995 and 1996 were similar, but more than $40,000
favorable to interest expense in 1994 due to a larger proportion of customer
advance payments received against orders (resulting in higher average cash
balances).

   
       The provision for income taxes in 1996 was a tax benefit of $59,000. In
1995, income tax expense was $52,000. In 1996 the Company reduced its deferred
tax valuation allowance to recognize operating loss carryforwards that are
realizable this year and set up an asset that it believes will be realized in
the future.
    

       Other income decreased by $11,000 in 1996 from 1995. In 1995, other
income decreased by $135,000 from 1994 due to the sale of a licensing agreement
in 1994.

       ASCOR recorded profits of $839,000, or $0.15 per share, in 1996, an
increase in income per share from $0.12 per share in 1995, and a decrease in
income from $0.22 per share in 1994. The improved results in 1996 were due to
increased sales of 47% and the tax benefit. The decrease from 1995 to 1994 was
primarily due to the 1994 licensing agreement sale, decreased gross margins and
an increase in operating expenses resulting from additions to ASCOR's management
team.

   
Financial Condition and Liquidity

       At year-end 1996, ASCOR had $451,000 in cash, cash equivalents and
investments, compared to $1,265,000 at the beginning of the year. Most of the
decrease resulted from a decrease in customer advances, additional capital
expenditures and higher receivables. The higher receivables in 1996 were due to
a 72 percent increase in shipments from the fourth quarter of fiscal 1995 to the
fourth quarter of fiscal 1996, and a relatively large portion of the Q4
shipments were recorded in March. The accounts receivable allowance, which was
zero at previous year-ends amounted to $13,000 because of one invoice deemed to 
be potentially uncollectible. Cash used in operations amounted to $514,000 in 
1996, compared to cash provided from operations of $428,000 in 1995, and cash 
provided from operations of $1,085,000 in 1994. The 1995 cash provided from  
operations was due to earnings and customer advances, offset primarily by an 
increase in inventories. The 1994 cash provided by operations was due to 
earnings.
    

                                      -69-
<PAGE>   77
   
       The working capital position at year-end of ($1,222,000) compared
unfavorably to ($796,000) at the end of 1995 due to the redeemable preferred
stock.

       Additions to property and equipment were $277,000 in 1996, compared to
$75,000 and $65,000 in 1995 and 1994, respectively. This spending reflects
continuing investments to support new product development, increase productivity
and improve product quality. Other cash outflows for investing activities
included $100,000 in 1996 and $200,000 in 1995 for purchases of short-term
investments. Cash outflows from financing activities were negligible.

INDEPENDENT AUDITOR'S REPORT

The Board of Directors and Shareholders
Giga-tronics Incorporated:



         We  have  audited  the  accompanying  balance  sheets  of  Giga-tronics
Incorporated  as of  March  30,  1996,  and  March  25,  1995,  and the  related
statements  of  operations,   shareholders'   equity  and  cash  flows  for  the
fifty-three week period ended March 30, 1996, and for each of the fifty-two week
periods in the two-year period ended March 25, 1995. These financial  statements
are the  responsibility of the Company's  management.  Our  responsibility is to
express an opinion on these financial statements based on our audits.

         We conducted our audits in accordance with generally  accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion,  the  financial  statements  referred to above  present
fairly,  in all  material  respects,  the  financial  position  of  Giga-tronics
Incorporated  as of March 30, 1996,  and March 25, 1995,  and the results of its
operations  and its cash flows for the  fifty-three  week period ended March 30,
1996,  and for each of the fifty-two  week periods in the two-year  period ended
March 25, 1995, in conformity with generally accepted accounting principles.

                         Notes to Financial Statements

   1     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   
         Description  of  Operations  The  Company  designs,  manufacturers  and
         markets  microwave and radio frequency (RF) signal generation and power
         measurement  instruments.  The market  for the  Company is the test and
         measurement industry.  These products are used primarily in the design,
         production,  repair and maintenance of wireless  communications,  radar
         and electronic warfare systems.  The Company has no foreign operations,
         and all non-U.S. sales are made in U.S. dollars, and therefore there is
         no currency risk on these transactions.
    

         Use of  Estimates  Management  of the  Company  has  made a  number  of
         estimates  and  assumptions  relating  to the  reporting  of assets and
         liabilities and the disclosure of contingent  assets and liabilities to
         prepare  these  financial   statements  in  conformity  with  generally
         accepted accounting principles.  Actual results could differ from these
         estimates.

         Revenue Recognition  Revenues are recognized when products are shipped.
         Interest income is recognized when earned.

         Cash  Equivalents For purposes of the  accompanying  statements of cash
         flows,  the Company  considers all highly liquid debt  instruments with
         maturity  dates of 90 days or less  from  date of  purchase  to be cash
         equivalents.

         Inventories Inventories are stated at the lower of cost or market. Cost
         is determined on a first-in, first-out basis.

         Property  and  Equipment  Property  and  equipment  are stated at cost.
         Depreciation  is  calculated  using the  straight-line  method over the
         estimated useful lives of the respective assets,  which range from 3 to
         10 years.  Leasehold improvements are amortized using the straight-line
         method over the shorter of the estimated useful lives of the respective
         improvements or the lease term.

         Income Taxes The Company  accounts for income taxes in accordance  with
         SFAS No. 109, "Accounting for Income Taxes." SFAS No. 109 prescribes an
         asset  and  liability  approach  that  results  in the  recognition  of
         deferred  tax  assets  and  liabilities  for the  expected  future  tax
         consequences  of  events  that have been  recognized  in the  Company's
         financial   statements  or  tax  returns.   In  estimating  future  tax
         consequences,  SFAS No. 109  generally  considers  all expected  future
         events other than enactment of changes in tax laws or rates.

         Patents and Licenses Patents and licenses are being amortized using the
         straight-line  method over periods of five to seven years.  As of March
         30, 1996 and March 25, 1995,  accumulated  amortization  on patents and
         licenses was $1,741,000 and $1,180,000, respectively.

         Earnings  (Loss)  Per Share  Earnings  (loss)  per  common  and  common
         equivalent  share is based on the weighted  average number of shares of
         common stock and dilutive common stock  equivalent  shares  outstanding
         during the year.
   
         Investments  During  fiscal  1995,  the Company  adopted  Statement  of
         Financial  Accounting Standards (SFAS) No. 115, "Accounting for Certain
         Investments in  Debt and  Equity  Securities."   The effect of adopting
         FAS 115  was not  material to  the Company's  financial position.  This
         statement  addresses  the  accounting  and reporting for investments in
         equity  securities that have readily  determinable  fair values and for
         all investments in debt securities.   The  Company's   investments have
         been classified  as available-for-sale  securities and  are reported at
         fair  value.  Unrealized  gains  and  losses  have  been  reported as a
         separate component of shareholders' equity.
    

         Concentration  of  Credit  Risk  and  Financial  Instruments  Financial
         instruments,  which  potentially  subject the  Company to credit  risk,
         consist principally of investments and trade accounts  receivable.  The
         Company's  investments  consist  principally of variable and fixed rate
         bonds  issued by state and local  governmental  agencies.  The  Company
         individually  evaluates  the  creditworthiness  of  its  customers  and
         generally does not require collateral or other security.  Historically,
         the Company has not incurred any significant credit related losses.

         Fair Market Value of Financial  Instruments The carrying amount for the
         Company's trade accounts receivable, accounts payable and other accrued
         expenses  approximates  fair market value because of the short maturity
         of these financial instruments.

         Recent  Accounting   Pronouncements  In  October,  1995  the  Financial
         Accounting  Standards  Board  issued  SFAS  No.  123,  "Accounting  for
         Stock-Based  Compensation."  SFAS No. 123 will be effective  for fiscal
         years  beginning  after  December 15,  1995,  and will require that the
         Company either  recognize in its financial  statements costs related to
         its employee  stock-based  compensation plans, such as stock option

         and stock purchase plans,  or make pro forma  disclosures of such costs
         in a footnote to the financial statements.

         The Company expects to continue to use the intrinsic value-based method
         of  Accounting  Principles  Board Opinion No. 25, as allowed under SFAS
         No. 123, to account for all of its  employee  stock-based  compensation
         plans.  Therefore,  in its financial  statements  for fiscal 1997,  the
         Company will make the required pro forma  disclosures  in a footnote to
         the  financial  statements.  SFAS  No.  123 is not  expected  to have a
         material  effect on the  Company's  results of  operations or financial
         position.

   2     CASH, CASH EQUIVALENTS AND INVESTMENTS

         Cash and cash  equivalents  consist of bank and money market  accounts,
         variable and fixed rate bonds, and fixed rate municipal notes which are
         stated at cost.  Investments  consist of municipal  notes and bonds and
         U.S.  Treasury Bills of varying  maturities.  The cash  equivalents and
         investments  mature  or are  marketable  within  30  days,  thus  being
         available for current  operating cash needs.  As of March 30, 1996, the
         interest rates on cash, cash  equivalents  and investments  ranged from
         3.5% to 6.6%.

         As of March 30, 1996 and March 25, 1995, the Company had $3,822,000 and
         $4,249,000, respectively, invested in variable and fixed rate bonds and
         fixed rate notes  issued by  governmental  agencies.  The  portfolio is
         diversified, consisting of five and six different governmental agencies
         located in various  geographic regions of the United States as of March
         30, 1996 and March 25, 1995, respectively.

   3     ESTIMATED VALUE OF INVESTMENTS

         Certain cash  equivalents and all  investments  have been classified as
         available-for-sale  securities,  and as of March 30, 1996  consisted of

   8     STOCK OPTION AND EMPLOYEE BENEFIT PLANS

         Stock  Option  Plans In March  1990,  the Company  established  a stock
         option plan which  provided for the granting of up to 300,000 shares of
         common  stock at 100% of fair market  value at the date of grant,  with
         each grant  needing  approval by the Board of Directors of the Company.
         Options  granted vest in one or more  installments  as set forth in the
         option agreement and must be exercised while the grantee is employed by
         the Company or within a certain period after termination of employment.
         Options granted to employees shall not have terms in excess of 10 years
         from the grant date.  In May 1994,  the Company  amended the 1990 Stock
         Option  Plan to allow  the total  number  of  shares  of  common  stock
         available  for issuance to be  increased  by 100,000  shares to 400,000
         shares.  During fiscal 1995,  the Company  offered  option  holders the
         opportunity to have outstanding options repriced to current fair value,
         with the related  vesting period  starting over. The Company  cancelled
         and  reissued  (repriced)  77,900  options  pursuant to the  repricing.
         Options granted vest in annual installments and must be exercised while
         the  grantee is  employed by the  Company,  or within a certain  period
         after  termination  of employment.  During fiscal 1996,  45,000 options
         were  exercised.  As of March 30,  1996,  the total number of shares of
         common stock  available for issuance is 355,000.  As of March 30, 1996,
         157,900 options for shares have been granted,  all of which have a term
         of 5 years.
                  Holders of options may be granted  stock  appreciation  rights
         which  entitle  them  to  surrender  outstanding  options  for  a  cash
         distribution  under  certain  changes in ownership  of the Company,  as
         defined in the stock option plan.

         The aggregate  rental  expense was  $637,000,  $568,000 and $595,000 in
         fiscal 1996, 1995 and 1994, respectively.

         The Company maintains a $2,000,000 line of credit collateralized by all
         of the Company's  assets.  This line of credit bears  interest at prime
         plus 2.25% and expires on July 31, 1996. As of March 30, 1996,  none of
         this line has been utilized.

   10    SUBSEQUENT EVENT

         On May 2, 1996 the  Company  entered  into an  agreement  to merge with
         ASCOR, Inc., a private company that designs, manufactures and markets a
         line of switching and connecting devices.  The merger will be accounted
         for as a  pooling-of-interests.  Accordingly the historical accounts of
         ASCOR will be combined  with those of the Company as if they had always
         been merged.  The merger is expected to be effective in June 1996.  The
         merger is subject to final approval of the  transaction by Giga-tronics
         and ASCOR shareholders.

         If the merger had been  effective  as of March 30, 1996  revenues,  net
         earnings  (loss)  and  earnings  (loss)  per share  would  have been as

INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders

ASCOR Incorporated:

We have audited the accompanying balance sheets of ASCOR Incorporated (the
Company) as of March 31, 1996, and 1995, and the related statements of
operations, shareholders' deficit and cash flows for the each of the years in
the three-year period ended March 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         As discussed in Note 14 to these financial statements, the Company is
expected to merge with Giga-tronics Incorporated, a publicly held company, early
in fiscal year 1997, subject to final approval of the transaction by
Giga-tronics and ASCOR shareholders.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of ASCOR Incorporated
as of March 31, 1996, and 1995, and the results of its operations and its cash
flows for each of the years in the three-year period ended March 31, 1996, in
conformity with generally accepted accounting principles.

                          Notes to Financial Statements

1        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Description of Operations The Company designs and manufactures modular,
         computer-based automatic test system equipment used for testing
         computer assemblies. The Company's customer base is primarily defense
         related companies located in the United States.

         Use of Estimates Management of the Company has made a number of
         estimates and assumptions relating to the reporting of assets and
         liabilities and the disclosure of contingent assets and liabilities to
         prepare these financial statements in conformity with generally
         accepted accounting principles. Actual results could differ from these
         estimates.

         Revenue Recognition The Company receives advances from its major
         customers for the purchase of inventory and funding of production to
         fulfill purchase order requirements. Sales are recognized when the
         products are shipped. In 1996 there were very few advances from
         customers.

         Cash Equivalents For purposes of the accompanying statements of cash
         flows, the Company considers all highly liquid debt instruments with
         maturity dates of 90 days or less from date of purchase to be cash
         equivalents.

         Investments Investments consist of certificates of deposit with
         original maturities greater than 90 days.

         Inventories Inventories consist of raw materials and work-in-process
         and are stated at the lower of cost or market. Cost is determined on a
         first-in, first-out basis.

         Property and Equipment Property and equipment are stated at cost.
         Depreciation is calculated using the straight-line method over the
         estimated useful lives of the respective assets, which range from 3 to
         7 years.

         Capital Leases Assets and liabilities are recorded at amounts equal to
         the lesser of the present value of the minimum lease payments on the
         lease obligations or the fair market value of the leased equipment at
         the beginning of the lease terms. Interest expensed relating to the
         lease liabilities is recorded to effect a constant rate of interest
         over the terms of the leases.

         Income Taxes The Company accounts for income taxes in accordance with
         Statement of Financial Accounting Standards (SFAS) No. 109, Accounting
         for Income Taxes. SFAS No. 109 prescribes an asset and liability
         approach that results in the recognition of deferred tax assets and
         liabilities for the expected future tax consequences of events that
         have been recognized in the Company's financial statements or tax
         returns. In estimating future tax consequences, SFAS No. 109 generally
         considers all expected future events other than enactment of changes in
         tax laws or rates.

         Earnings Per Share Earnings per common and common equivalent share is
         based on the weighted average number of shares of common stock and
         dilutive common stock equivalent shares outstanding during the year.
         Net earnings available to common shareholders is reduced by the
         accruable, but undeclared, dividends due on Series A, Series B, and
         Series C preferred stock.

         Product Development Costs Product development costs are charged to
         operations in the year incurred.

         Concentration of Credit Risk and Financial Instruments The Company
         maintains its cash in commercial checking and money market accounts and
         certificates of deposit.

         Fair Market Value of Financial Instruments The carrying amount for the
         Company's investments, trade accounts receivable, accounts payable,
         notes payable and other accrued expenses approximates fair market value
         because of the short maturity of these financial instruments.

         Recent Accounting Pronouncements In October, 1995 the Financial
         Accounting Standards Board issued SFAS No. 123, Accounting for
         Stock-Based Compensation. SFAS No. 123 will be effective for fiscal
         years beginning after December 15, 1995, and will require that the
         Company either recognize in its financial statements costs related to
         its employee stock-based compensation plans, such as stock option and
         stock purchase plans, or make pro forma disclosures of such costs in a
         footnote to the financial statements.

<PAGE>   108
                                  ASCOR, Inc.

                          Notes to Financial Statements

         The Company expects to continue to use the intrinsic value-based method
         of Accounting Principles Board Opinion No. 25, as allowed under SFAS
         No. 123, to account for all of its employee stock-based compensation
         plans. Therefore, in its financial statements for fiscal 1997, the
         Company will make the required pro forma disclosures in a footnote to
         the financial statements. SFAS No. 123 is not expected to have a
         material effect on the Company's results of operations or financial
         position.

2        CASH, CASH EQUIVALENTS AND INVESTMENTS

         Cash and cash equivalents consist of bank accounts and certificates of
         deposit. The certificates of deposits have maturity dates between 90
         and 180 days, maturing in April and May 1996, and bear interest from
         5.45% to 5.6%. Certificates of deposit which have original maturities
         greater than 90 days are considered short-term investments and are
         stated at cost which approximates market value.

3        SALES TO SIGNIFICANT CUSTOMERS

   
         The Company had sales to two customers in 1996, three customers in
         1995, and three customers in 1994, which amounted to approximately
         $3,758,000, $3,027,000, and $2,970,000 of gross revenues for the years
         ended March 31, 1996, 1995, and 1994, respectively.

         contributions to the plan up to 15% of their defined compensation. The
         Company is required to match 10% of the amount contributed by plan
         participants. Participants vest ratably in the Company contribution
         over a four-year period. Company contributions to the plan for fiscal
         1996,1995 and 1994 were approximately $9,231, $5,586, and $ 0,
         respectively.

         Under the lease, the Company is required to pay monthly operating
         expenses in addition to the monthly rent payments. Rent expense,
         including related occupancy costs, was approximately $97,757, $93,951,
         and $89,620 for the years ended March 31, 1996, 1995 and 1994.

12       REDEEMABLE PREFERRED STOCK

         Dividends The holders of each series of preferred stock are entitled to
         receive cumulative dividends, out of any available funds, accruing
         quarterly beginning September 30, 1992 of $.047 per share of Series A
         preferred stock per year, $.05 per share of Series B preferred stock
         per year, and $.055 per share of Series C preferred stock per year
         payable in preference and priority to any payment of any dividend on
         common stock of the Company. As of March 31, 1996, accumulated but
         undeclared dividends on cumulative Series A, Series B, and Series C
         preferred stock was approximately $910,000. In 1994, 1995 and 1996,
         dividends accrued amounted to $260,000 in each year for Series A, B and
         C preferred stock.

         Conversion Each share of Series A, Series B and Series C preferred
         stock is convertible into the number of shares of common stock that
         results from dividing the original issue price by the "conversion
         price" in effect at that time. As of March 31, 1996, the conversion
         price was $0.47, $0.50, and $0.55 for Series A, Series B, and Series C
         preferred stock, respectively. Each share of preferred stock will be
         automatically converted upon the effectiveness of a registration
         statement under the Securities Act of 1933, if the public offering is
         at least $2.75 per share and total proceeds equal or exceed $5,000,000.

         Voting Rights Each share of preferred stock has voting rights equal to
         its common stock equivalents.

         Liquidation Preference In the event of liquidation, the holders of the
         Series B preferred and Series C preferred are entitled to receive
         distributions on a prorata basis, in preference to the holders of the
         Series A preferred and the holders of common stock.

         Redemption To the extend of legally available funds, the Company shall
         redeem on each of September 30, 1995, September 30, 1996, and September
         30, 1997 one third of the Series A, Series B and Series C preferred
         shares at the original issue price, plus any accrued but unpaid
         dividends.

         Proposed Merger As a result of the proposed merger, (see footnote 14),
         it is expected that the preferred shareholders will exchange their
         preferred stock interests for common stock of ASCOR prior to the
         Merger, and will subsequently receive Giga-tronics stock in exchange
         for these interests. None of the redeemable preferred stock will be
         redeemed prior to the Merger. There are no plans to pay the dividends
         prior to the Merger, since no dividends have been declared. The
         Giga-tronics common stock, which the ASCOR preferred shareholders
         will receive, will not include any consideration for undeclared
         dividends. 
    

13       RESERVED COMMON STOCK

         As of March 31, 1996, the Company has reserved 11,346,061 shares of
         common stock for future issuance upon the exercise of stock warrants
         and the conversion of preferred stock.

         Additionally, in conjunction with bridge financing agreements entered
         into during the period of April through December, 1991, warrants to
         purchase 6,096,545 shares of common stock were issued. These warrants,
         which are exercisable at $.07 per share, expire five years from the
         date of issuance between April and December, 1996.

14       SUBSEQUENT EVENT

         On May 2, the Company entered into an agreement to merge with
         Giga-tronics Inc., a publicly held company. It is intended that the
         transaction will be accounted for as a pooling of interests.

                      AGREEMENT AND PLAN OF REORGANIZATION


                  THIS AGREEMENT AND PLAN OF REORGANIZATION  (this  "Agreement")
is  entered  into  as of the 2nd day of May,  1996,  by and  among  Giga-tronics
Incorporated,  a  California  corporation  ("Giga-tronics"),  ASCOR  Acquisition
Corp., a California  corporation  and a wholly owned  subsidiary of Giga-tronics
("Merger Sub"), and ASCOR, Inc., a California corporation ("ASCOR").


                                    RECITALS

                  A. The Boards of  Directors  of  Giga-tronics,  Merger Sub and
ASCOR have each determined to engage in the  transactions  contemplated  hereby,
pursuant to which (i) Merger Sub will merge (the  "Merger") with and into ASCOR,
(ii) each share of common stock,  no par value,  of ASCOR ("ASCOR Common Stock")
and any other shares of ASCOR stock which shall have  previously  been converted
into  Ascor  Common  Stock  (except  for  shares  of  ASCOR  stock  as to  which
dissenters' rights, if available,  shall have been perfected) shall be converted
into the right to receive a fraction of a share of common  stock,  no par value,
of Giga-tronics  ("Giga-tronics  Common Stock"), in the manner and amount herein
described,  and (iii) the capital  stock of Merger Sub shall be  converted  into
shares of ASCOR Common Stock,  all upon the terms and subject to the  conditions
set forth herein.

                  B. The  Board of  Directors  of ASCOR  has  approved,  and has
resolved to recommend that the  shareholders  of ASCOR  approve,  the Merger and
this Agreement.

                  C. The  respective  Boards of  Directors of  Giga-tronics  and
Merger Sub have approved the Merger and this  Agreement.  The Board of Directors
of Giga-tronics  has resolved to recommend that the shareholders of Giga-tronics
approve the Merger and this Agreement.  Giga-tronics, as the sole shareholder of
Merger Sub, has approved the Merger and this Agreement.

                  D. The parties  intend for the  transactions  contemplated  by
this Agreement to qualify as a tax-free  reorganization  in accordance  with the
provisions  of Section  368(a) of the Internal  Revenue Code of 1986, as amended
(the "Code"), and to be accounted for as a pooling of interests transaction.

                  NOW,  THEREFORE,  in  consideration  of the  foregoing and the
mutual representations,  warranties,  covenants and agreements set forth herein,
the parties agree as follows:

                                       1.

                                   THE MERGER

         SECTION 1.01         THE MERGER.

                      (a)  Subject to the terms and  conditions  hereof,  and in
accordance with the General  Corporation  Law of California,  Merger Sub will be
merged with and into ASCOR (the "Merger"),  as soon as practicable following the
satisfaction  or  waiver  of the  conditions  set forth in  Article  VI  hereof.
Following the Merger,  ASCOR shall  continue as the surviving  corporation  (the
"Surviving  Corporation"),  and the separate  corporate  existence of Merger Sub
shall cease.

                      (b) Concurrent  with the Closing (as defined in subsection
(d) below),  Giga-tronics,  and ASCOR and Merger Sub shall file an  agreement of
merger in the form attached  hereto as Exhibit 1.01 (the  "Agreement of Merger")
in the Office of the Secretary of State of the State of California in accordance
with  California  Law.  The Merger  shall  become  effective at such time as the
Agreement of Merger is duly filed in the Office of the Secretary of State of the
State of California  (the date of such filing being  hereinafter  referred to as
the "Effective Date" and the time of such filing being  hereinafter  referred to
as the "Effective Time").

                      (c) From and  after  the  Effective  Time,  the  Surviving
Corporation shall possess all the rights, privileges,  powers and franchises and
be  subject  to all of the  restrictions,  disabilities  and duties of ASCOR and
Merger Sub, all as provided under California Law.

                      (d) The closing of the  transactions  contemplated by this
Agreement  (the  "Closing")  shall take place on June 27, 1996 at the offices of
Brobeck Phleger & Harrison LLP, One Market Plaza, San Francisco, CA 94105, or at
such other date and place as Giga-tronics and  ASCOR may agree.  The date of the
Closing  determined  pursuant  to this  Section  1.01(d) is  referred  to as the
"Closing Date."

         SECTION 1.02         CONVERSION OF SHARES.

                      (a)     At the Effective Time:

                              (i)  Subject  to  Section  1.05  hereof,   at  the
         Effective Time each issued and outstanding share of ASCOR Common Stock,
         Series A Preferred Stock of ASCOR (the "ASCOR Series A Shares"), Series
         B Preferred  Stock of ASCOR (the "ASCOR  Series B Shares") and Series C
         Preferred Stock of ASCOR (the "ASCOR Series C Shares" and  collectively
         with the  ASCOR  Series A Shares  and the ASCOR  Series B  Shares,  the
         "ASCOR Preferred  Shares") issued and outstanding  immediately prior to
         the Effective Time (other than  Dissenting  ASCOR Shares (as defined in
         Section 1.04 hereof)) shall automatically,  by virtue of the Merger and
         without any action on the part of the holder thereof, be converted into
         a right to

                                       2.
<PAGE>   121
         receive  the  number  of  shares  of  Giga-tronics  Common  Stock as is
         determined  pursuant to this Section  1.02.  The ASCOR Common Stock and
         ASCOR  Preferred  Shares  are  collectively  referred  to herein as the
         "ASCOR  Shares."  A maximum  total of  724,986  shares of  Giga-tronics
         Common Stock (the "Merger Consideration") will be issued in the Merger,
         including  (1)  shares  issuable  in respect  of any  warrants  for the
         purchase of ASCOR Common Shares ("ASCOR Common  Warrants") and warrants
         for the  purchase  of any  series  of  ASCOR  preferred  stock  ("ASCOR
         Preferred Warrants") (the ASCOR Common Warrants and the ASCOR Preferred
         Warrants are referred to  collectively as the "ASCOR  Warrants")  which
         remain outstanding at the Effective Time, (2) shares deemed surrendered
         on  exercise  of any  ASCOR  Warrant  for which a deemed  net  exercise
         pursuant  to Section  1.06 below has been made;  (3) shares  that would
         have  been  issued to  holders  of  Dissenting  ASCOR  Shares;  and (4)
         fractional  shares that would have been  issuable  but for Section 1.05
         below.

                              (ii) The  Agreement  of Merger  to be filed  shall
         contain  the final  exchange  ratio (the  "Exchange  Ratio")  for ASCOR
         Shares  into  Giga-tronics  Common  Stock and shall be equal to 724,986
         divided by the fully diluted number of ASCOR Shares  outstanding at the
         Effective Time (the "ASCOR Outstanding  Equivalent Number").  The ASCOR
         Outstanding  Equivalent  Number  shall  be  equal to the sum of (1) the
         number of ASCOR Shares  outstanding at the Effective time; plus (2) the
         total number of ASCOR Shares which would be issuable on the exercise of
         any ASCOR Warrants or ASCOR Options (as such terms are defined  below).
         All ASCOR Shares shall be exchangeable into  Giga-tronics  Common Stock
         at the same Exchange Ratio.

                      (b)  If  between  the  date  of  this  Agreement  and  the
Effective Time, the number of outstanding ASCOR Shares or shares of Giga-tronics
Common  Stock shall have been  changed  into a  different  number of shares or a
different class, by reason of any stock dividend, subdivision, reclassification,
recapitalization,  split-up,  combination,  exchange of shares or the like,  the
Exchange Ratio shall be correspondingly adjusted.


         SECTION 1.03         EXCHANGE OF CERTIFICATES.

                      (a)  Giga-tronics  (or such  third  party as  Giga-tronics
shall appoint)  shall act as Exchange Agent (the "Exchange  Agent") for delivery
of the Merger  Consideration to the ASCOR  shareholders and, if applicable,  the
cash to which holders of ASCOR shares shall be entitled pursuant to Section 1.05
hereof.

                      (b) As soon as practicable  after the Effective  Time, the
Exchange Agent shall mail to each holder of record (other than  Giga-tronics  or
Merger  Sub or  any  other  subsidiary  of  Giga-tronics)  of a  certificate  or
certificates  which immediately  prior to the Effective Time represented  issued
and outstanding ASCOR Shares  (individually a "Certificate" and collectively the
"Certificates"),  a letter of transmittal for return to the Exchange Agent which
shall specify that delivery shall be effected, and risk of loss and the

                                       3.
<PAGE>   122
title to the  Certificates  shall pass, only upon receipt of the Certificates in
exchange  for the Merger  Consideration.  Upon  surrender of a  Certificate  for
cancellation  to the Exchange  Agent,  together with and in accordance with such
letter of  transmittal,  the holder of such  Certificate  shall be  entitled  to
receive in  exchange  therefor  the  Merger  Consideration  that such  holder is
entitled to receive pursuant to Section 1.02(a) hereof.  Upon such surrender the
Exchange Agent shall promptly deliver such Merger Consideration.

                      (c) Until  surrendered,  each Certificate  shall be deemed
for all purposes to evidence only the right to receive the Merger  Consideration
into which ASCOR Shares formerly  represented  thereby shall have been converted
pursuant to Section 1.02(a) hereof. No dividends or other distribution  declared
after the  Effective  Time with respect to Giga-  tronics  Common Stock shall be
paid to the holders of any  unsurrendered  Certificate  until the holder thereof
surrenders such Certificate.

                      (d) After the  Effective  Time there shall be no transfers
on the stock  transfer  books of either ASCOR (the stock transfer books of which
shall be  closed)  or the  Surviving  Corporation  of ASCOR  Shares  which  were
outstanding immediately prior to the Effective Time. If after the Effective Time
Certificates  are presented for transfer to the Exchange Agent,  together and in
accordance with the letter of transmittal from the Exchange Agent, they shall be
cancelled and exchanged for the Merger Consideration.

         SECTION 1.04 DISSENTING  SHARES.  ASCOR Shares that have not been voted
for  approval of this  Agreement  and with respect to which a demand for payment
and appraisal shall have been properly made in accordance with Chapter 13 of the
General  Corporation Law of California  ("Dissenting ASCOR Shares") shall not be
converted  into the right to receive  the Merger  Consideration  at or after the
Effective   Time  but  shall  be  converted  into  the  right  to  receive  such
consideration  as may be  determined  to be due with respect to such  Dissenting
ASCOR  Shares  pursuant  to the law of the State of  California.  If a holder of
Dissenting ASCOR Shares  ("Dissenting  Shareholder"),  shall withdraw his or her
demand for such  payment  and  appraisal  or shall  become  ineligible  for such
payment and appraisal,  then, as of the Effective Time of the occurrence of such
event of  withdrawal  or  ineligibility,  whichever  last occurs,  such holder's
Dissenting  ASCOR Shares shall cease to be Dissenting  ASCOR Shares and shall be
converted into the right to receive,  and shall be exchangeable  for, the Merger
Consideration  into which such Dissenting ASCOR Shares would have been converted
pursuant to Section 1.02(a) hereof.  ASCOR shall give Giga-tronics prompt notice
of any demand  received by ASCOR from a holder of  Dissenting  ASCOR  Shares for
appraisal of ASCOR Shares,  and Giga-tronics shall have the right to participate
in all negotiations  and proceedings  with respect to such demand.  ASCOR agrees
that,  except with the prior  written  consent of  Giga-tronics,  or as required
under the General  Corporation Law of California,  it will not voluntarily  make
any payment with  respect to, or settle or offer to settle,  any such demand for
appraisal.  Each  Dissenting  Shareholder  who,  pursuant to the  provisions  of
Chapter 13 of the General  Corporation  Law of California,  becomes  entitled to
payment of the value of shares of ASCOR stock  shall  receive  payment  therefor
(but only  after the value  therefor  shall  have been  agreed  upon or  finally
determined  pursuant to such provisions).  Any Merger  Consideration which would
have been issuable with respect to Dissenting  ASCOR Shares shall be retained by
Giga-tronics.

                                       4.
<PAGE>   123
         SECTION 1.05 FRACTIONAL SHARES.  Notwithstanding any other provision of
this  Agreement to the contrary,  no fractional  shares of  Giga-tronics  Common
Stock shall be issued in connection with the Merger.  All shares of Giga-tronics
Common Stock to which a holder of ASCOR Shares is entitled  immediately prior to
the Effective Time shall be aggregated.  If a fractional share results from such
aggregation,  in lieu of any such fractional  share, each holder of ASCOR Shares
who would  otherwise  have been  entitled  to receive a  fraction  of a share of
Giga-tronics  Common Stock upon surrender of Certificates for exchange  pursuant
to Section  1.03 shall be entitled  to receive  from the  Exchange  Agent a cash
payment equal to such fraction multiplied by the closing sale price per share of
Giga-tronics  Common Stock on the last business day on which Giga-tronics Common
Stock is traded on the NASD, prior to the Effective Time.

         SECTION 1.06         ASCOR STOCK OPTIONS AND WARRANTS.

                      (a)  Except  as  described   below  in  Section   1.06(b),
Giga-tronics  will not assume any options for the  purchase of ASCOR  Shares (an
"ASCOR Option") or ASCOR  Warrants.  At the Effective  Time,  outstanding  ASCOR
Options and ASCOR Warrants  shall be deemed  exercised for such number of shares
of  Giga-tronics  Common Stock as would be exchanged in the Merger for the ASCOR
Shares  which  would have been issued had such ASCOR  Options or ASCOR  Warrants
been exercised in full and such ASCOR Shares been outstanding  immediately prior
to the Effective Time, subject to the following provisions of this Section 1.06.
Such deemed  exercise of ASCOR  Options  and ASCOR  Warrants  shall be on a "net
exercise"  basis.  The full number of shares  issuable on exercise of such ASCOR
Warrant  or  ASCOR  Option  (including  such  number  of  shares  as are  deemed
surrendered  in the net  exercise)  shall  be  added  to the  ASCOR  Outstanding
Equivalent  Number as described  in Section  1.02 above.  The value of the ASCOR
Shares  issuable  on the  exercise  of any ASCOR  Warrant  or ASCOR  Option  for
purposes of  determining  the number of ASCOR  Shares to be  surrendered  in the
deemed net  exercise  shall be equal to the number of ASCOR  Shares  issuable on
exercise  of such ASCOR  Warrant or ASCOR  Option,  multiplied  by the  Exchange
Ratio,  multiplied by the average closing price of a share of Giga-tronics Stock
on such stock  exchange  as  Giga-tronics  Stock is then traded for the five (5)
business days  immediately  preceding the Closing Date.  Shares of  Giga-tronics
Common  Stock which would  otherwise  be issuable in respect of the ASCOR Shares
deemed surrendered upon such net exercise shall be retained by Giga-tronics.

                      (b)  Notwithstanding  the  foregoing,  any  ASCOR  Warrant
which,  based  upon the  foregoing  determination  of the value of ASCOR  Shares
issuable  on its  exercise,  would be  "out-of-the-money"  shall be  assumed  by
Giga-tronics.  An ASCOR Warrant shall be deemed out-of-the-money if its exercise
price per share is greater than the value of such share as determined in Section
1.06(a)  above.   Any  assumed  ASCOR  Warrant  shall  remain   outstanding  and
exercisable in accordance with its terms except that (1) it shall be exercisable
for such number of shares of  Giga-tronics  Common Stock as equals the number of
ASCOR Shares for which it was  exercisable  multiplied by the Exchange Ratio and
(2) the exercise  price per share of such warrant shall be the exercise price as
stated on such warrant  divided by the Exchange  Ratio.  The number of shares of
Giga-tronics  Common Stock as would be issuable on exercise in full of any ASCOR
Warrants assumed shall be

                                       5.
<PAGE>   124
reserved  out of the  Merger  Consideration.  If any ASCOR  Warrant  assumed  by
Giga-tronics  pursuant to this Section 1.06 shall expire  unexercised in full or
in part,  the  Giga-tronics  Common  Stock  which  would have been  issuable  on
exercise shall be retained by Giga-tronics and not otherwise issued.

         SECTION 1.07 NO REGISTRATION OF GIGA-TRONICS  COMMON STOCK. The parties
acknowledge and agree that the  Giga-tronics  Common Stock to be issued pursuant
to the Merger will be issued  pursuant to a  transaction  not involving a public
offering and therefore will be  characterized as "restricted  securities"  under
federal securities laws. The parties further acknowledge and agree that pursuant
to  the  Securities  Act  of  1933,  as  amended  (the  "Securities   Act")  the
Giga-tronics Common Stock so issued may be resold without registration under the
Securities Act only in certain limited circumstances.  It is understood that the
Certificates issued pursuant to the Merger will bear the following legend:

                      "These  securities  have not  been  registered  under  the
                      Securities Act of 1993, as amended.  They may not be sold,
                      offered for sale,  pledged or  hypothecated in the absence
                      of a registration  statement in effect with respect to the
                      securities  under  such  Act  or  an  opinion  of  counsel
                      satisfactory to the Company that such  registration is not
                      required or unless sold pursuant to Rule 144 of such Act."

                      Giga-tronics  shall  be under no  obligation  to  effect a
registration statement with respect to Giga-tronics Common Stock received in the
Merger other than as required pursuant to the Registration  Rights Agreement (as
such term is defined in Section 10.01 below).


                                   ARTICLE II

                            THE SURVIVING CORPORATION

         SECTION  2.01   CERTIFICATE  OF   INCORPORATION.   The  Certificate  of
Incorporation  of the  Surviving  Corporation  shall be amended at the Effective
Time to conform to the Certificate of  Incorporation of Merger Sub, as in effect
immediately prior to the Effective Time.

         SECTION 2.02 BYLAWS. The Bylaws of Merger Sub, as in effect immediately
prior to the Effective Time,  shall be the Bylaws of the Surviving  Corporation,
until thereafter amended in accordance with applicable law.

         SECTION 2.03 DIRECTORS AND OFFICERS. From and after the Effective Time,
until  successors are duly elected or appointed and qualified in accordance with
applicable  law, the directors of Merger Sub at the Effective  Time shall become
the initial directors of the Surviving Corporation, and the officers of ASCOR at
the  Effective  Time  shall  become  the  initial   officers  of  the  Surviving
Corporation.

                                       6.

Giga-tronics  no less than five days prior to the  execution  of this  Agreement
(which shall contain  appropriate  and  reasonably  detailed  references to each
representation and warranty to which any item there disclosed  pertains),  ASCOR
represents and warrants to Giga-tronics as set forth below:

         SECTION 3.01 CORPORATE EXISTENCE AND POWER. ASCOR is a corporation duly

Authorizations")  required to carry on its business as now  conducted.  ASCOR is
duly qualified to do business as a foreign  corporation  and is in good standing
in each  jurisdiction  where the character of the property owned or leased by it
or the nature of its activities makes such  qualification  necessary.  ASCOR has
delivered  to  Giga-tronics  true and  complete  copies of ASCOR's  Articles  of
Incorporation and Bylaws as currently in effect.

         SECTION  3.02  CORPORATE  AUTHORIZATION.  The  execution,  delivery and
performance by ASCOR of this Agreement,  the ASCOR and  Giga-tronics  Affiliates
Agreements (as defined in Sections 5.09 and 6.08  respectively,  hereof) and the
consummation by ASCOR of the  transactions  contemplated  hereby and thereby are
within ASCOR's  corporate  powers and have been duly authorized by all necessary
corporate action,  except for the approval by ASCOR's shareholders in connection
with the  consummation  of the  Merger.  The ASCOR and  Giga-tronics  Affiliates
Agreement  are   collectively   referred  to  herein  as  the  "ASCOR  Ancillary
Agreements." This Agreement and the ASCOR Ancillary  Agreements  constitute,  or
upon  execution  will  constitute,   valid  and  binding  agreements  of  ASCOR,
enforceable against ASCOR in accordance with their respective terms.

         SECTION 3.03 GOVERNMENTAL  AUTHORIZATION.  The execution,  delivery and
performance by ASCOR of this Agreement,  the ASCOR Ancillary  Agreements and the
Agreement  of Merger  and the  consummation  of the  Merger by ASCOR  require no
action by or in respect  of, or filing  with,  any  governmental  body,  agency,
official or authority other than:

                      (a) the filing of the  Agreement  of Merger in  accordance
with California Law;

respect to any writ, order,  judgment,  injunction or decree, which would have a

any  liability  under,  and  has  complied  in all  respects  with,  the  Worker

officer,  director  or  employee  of  ASCOR,  whether  written  or oral  (each a
"Material ASCOR Agreement").

                      (b) Neither  ASCOR nor,  to the  knowledge  of ASCOR,  any
other party is in default  under any Material  ASCOR  Agreement and no event has
occurred  which (after notice or lapse of time or both) would become a breach or
default  under,  or would permit  modification,  cancellation,  acceleration  or
termination  of any  Material  ASCOR  Agreement or result in the creation of any
security  interest  upon,  or any person  obtaining  any right to  acquire,  any
properties, assets or rights of ASCOR.

                      (c) Each  Material  ASCOR  Agreement  is in full force and
effect and is valid and legally  binding,  there are, to the knowledge of ASCOR,
no  unresolved  disputes  involving  or  with  respect  to  any  Material  ASCOR

Material ASCOR Agreement upon the expiration of the term thereof.

                      (d)  ASCOR is not in  violation  of,  or in  default  with

property of ASCOR,  including any leased property,  and any material  buildings,
structures and improvements located thereon or therein, such buildings, fixtures
and  improvements,  and the  present  use  thereof,  are not the  subject of any
official  complaint or notice of violation of any applicable  zoning  ordinance,
building  code or  environmental  laws,  and such  premises  are not affected or
threatened by any condemnation or eminent domain proceeding.

                      (c) All leases of real property and all material leases of
personal  property  by ASCOR  are in full  force  and  effect  and,  to  ASCOR's
knowledge,  there  exists no default on the part of ASCOR which would  interfere
with the use made and  proposed to be made of such real and  personal  property,
and, except for leases of personal property terminated in the ordinary course of
business, upon consummation of the Merger, will continue to entitle ASCOR to the
use and  possession  of the real or personal  property  purported  to be covered
thereby for the terms  specified  in such leases and for the  purposes for which
such real or personal property is now used.

         SECTION 3.16 TITLE TO ASSETS. ASCOR has good,  marketable and insurable
title  to all the  properties  and  assets  it owns or uses in its  business  or

subject thereto,  (B) do not interfere with either the present and continued use
of such property or the conduct of ASCOR's normal operations and (C) have arisen
only in the ordinary course of business. All of the properties and assets owned,
leased or used by ASCOR are in good operating condition and repair, are suitable
for the purposes used, are adequate and sufficient for all current operations of
ASCOR and are directly related to the business of ASCOR.

         SECTION  3.18  INTELLECTUAL  PROPERTY.  No claim is pending  or, to the
knowledge of ASCOR, threatened to the effect that the present or past operations
of ASCOR  infringes  upon or conflicts with the rights of others with respect to
any intellectual  property (including,  without limitation,  licenses,  patents,
patent rights, patent applications,  trademarks,  trademark applications,  trade
names,  copyrights,  drawings,  trade secrets,  know-how and computer  software)
necessary to permit  ASCOR to conduct its  business as now operated  (the "ASCOR
Intellectual  Property"),  except as disclosed in the ASCOR Disclosure Schedule,
no claim is pending or, to the best knowledge of ASCOR, threatened to the effect
that any of the ASCOR Intellectual  Property is invalid or unenforceable.  ASCOR
has provided Giga-tronics with a list of all licenses,  patents,  patent rights,
patent applications, trademarks, trademark applications, trade names, copyrights
and service marks of ASCOR and each of its subsidiaries.  Except as set forth in
the ASCOR Disclosure Schedule,  no contract,  agreement or understanding between
ASCOR or any of its  subsidiaries  and any other party exists which would impede
or prevent the continued use by ASCOR and its  subsidiaries of the entire right,
title  and  interest  of  ASCOR  and  its  subsidiaries  in  and  to  the  ASCOR
Intellectual Property.

         SECTION 3.19 NO GUARANTIES.  None of the  obligations or liabilities of
ASCOR is  guaranteed  by, or subject to a similar  contingent  liability of, any

firm or corporation.

         SECTION 3.20 ABSENCE OF CERTAIN BUSINESS  PRACTICES.  Neither ASCOR nor
any  officer,  employee or agent of ASCOR,  nor any other  person  acting on its
behalf, has, directly or indirectly,  within the past five years given or agreed
to give any gift or similar  benefit  to any  customer,  supplier,  governmental
employee  or other  person who is or may be in a position  to help or hinder the
business  of ASCOR (or assist  ASCOR in  connection  with any actual or proposed
transaction)  which (a) might  subject  ASCOR to any  damage or  penalty  in any
civil,  criminal or governmental  litigation or proceeding,  (b) if not given in
the past, might have had an adverse effect on the assets, business or operations
of ASCOR as reflected in the Financial Statements or (c) if not continued in the
future, might adversely affect ASCOR's assets, business, operations or prospects
or which might subject  ASCOR to suit or penalty in any private or  governmental
litigation or proceeding.

         SECTION  3.21  COMPLIANCE  WITH LAWS AND OTHER  INSTRUMENTS.  ASCOR had
complied  with  all  existing  laws,  rules,  regulations,  ordinances,  orders,
judgments and decrees now  applicable to its business,  properties or operations
as presently conducted.  Neither the ownership nor use of ASCOR's properties nor
the conduct of its business conflicts with the rights of any other person,  firm
or  corporation  or  violates,  or with or  without  the giving of notice or the
passage of time, or both,  will  violate,  conflict with or result in a default,
right to  accelerate  or loss of rights  under,  any terms or  provisions of its
certificate  of  incorporation  or by-laws as presently in effect,  or any lien,
encumbrance, mortgage, deed of trust, lease, license, agreement,  understanding,
law, ordinance,  rule or regulation,  or any order,  judgment or decree to which
ASCOR is a party or by which it may be bound or affected.  Neither ASCOR nor any
Shareholder  is aware of any  proposed  laws,  rules,  regulations,  ordinances,
orders, judgments, decrees, governmental takings, condemnations

                                       16.
<PAGE>   135
or other  proceedings  which would be applicable to its business,  operations or
properties and which might adversely affect its properties, assets, liabilities,
operations or prospects, either before or after the Closing.

         SECTION 3.22 DISCLOSURE DOCUMENTS.  None of the information supplied or
to be supplied by ASCOR for  inclusion  in the proxy  statement  relating to the
meeting of  Giga-tronics's shareholders to be held in connection with the Merger
(the  "Proxy  Statement")  at the time of  mailing  of the  Proxy  Statement  to
shareholders  of  Giga-tronics,  and at the time of the meeting of  Giga-tronics
shareholders  to be held in  connection  with the  Merger,  contain  any  untrue
statement of a material  fact or omits or will omit to state any  material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in  light  of  the  circumstances  under  which  they  are  made,  not
misleading.  The Proxy Statement will comply as to form in all material respects
with  the  provisions  of  the  Exchange  Act  and  the  rules  and  regulations
thereunder,  except  that no  representation  is made by ASCOR  with  respect to
information supplied by Giga-tronics or Merger Sub for inclusion therein.

         SECTION 3.23 TAX MATTERS.  Neither ASCOR nor any of its  affiliates has
taken or agreed to take any action  that  would  prevent  the Merger  from being
effected as a pooling of interests or would prevent the Merger from constituting
a transaction qualifying under Section 368(a) of the Code. Neither ASCOR nor any
of  its  affiliates  or  agents  is  aware  of  any  agreement,  plan  or  other
circumstances that would prevent the Merger from qualifying under Section 368(a)
of the Code and to their best  knowledge  after due inquiry,  the Merger will so
qualify.

         SECTION 3.24 ACCOUNTING MATTERS.  Schedule 3.24 of the ASCOR Disclosure
Schedule  sets forth all persons who, as of the date of this  Agreement,  may be
deemed  to be  affiliates  of  ASCOR  under  Rule 145 of the  Securities  Act or
otherwise   under   applicable   SEC   accounting   releases   with  respect  to
pooling-of-interests  accounting treatment.  Prior to the date hereof, ASCOR has
advised such persons of the resale restrictions imposed by applicable securities
Laws and  required  to cause the  Merger  to  qualify  for  pooling-of-interests
accounting treatment.

promptly prepare and file with the SEC, will use all reasonable  efforts to have
cleared by the SEC and will thereafter  deliver to its  shareholders as promptly
as  practicable  the Proxy  Statement  and all other  proxy  materials  for such
meeting;

                      (b)  will  use  all  reasonable   efforts  to  obtain  the
necessary  approvals by its  shareholders of this Agreement and the transactions
contemplated hereby; and

                      (c) will  otherwise  comply  with all  legal  requirements
applicable to such meeting.

         SECTION 5.03 ACCESS TO FINANCIAL  AND OPERATION  INFORMATION.  From the
date hereof until the Effective Time, ASCOR will give Giga-tronics, its counsel,
financial  advisors,  auditors and other authorized  representatives  reasonable
access  during  normal  business  hours to the  offices,  properties,  books and
records  of  ASCOR,  will  furnish  to Giga-  tronics,  its  counsel,  financial

employees,  counsel and financial advisors to cooperate with Giga-tronics in its
investigation  of the business of ASCOR and in the planning for the  combination
of the businesses of ASCOR and  Giga-tronics  following the  consummation of the
Merger; provided that no investigation pursuant to this Section shall affect any
representation  or  warranty  given  by  ASCOR  to  Giga-tronics  hereunder.  In
addition, ASCOR will cooperate in arranging joint meetings among representatives
of ASCOR and  Giga-tronics  and  persons  with  whom  ASCOR  maintains  business
relationships.  All requests for information made pursuant to this Section shall

         SECTION  5.04 OTHER  OFFERS.  From the date hereof until the earlier of

agreement to merge or  consolidate  with, or sell a  substantial  portion of its
assets to, any person or entity.  ASCOR will promptly notify  Giga-tronics after
receipt of any  Acquisition  Proposal or any request for  nonpublic  information
relating to ASCOR in connection  with an  Acquisition  Proposal or for access to
the  properties,  books or records of ASCOR by any person or entity that informs
the  Board  of  Directors  that  it is  considering  making,  or  has  made,  an
Acquisition Proposal. The term "Acquisition Proposal" shall mean (i) any merger,

transaction hold following the consummation of such transaction less than 80% of
the voting securities of the surviving entity, (ii) a sale of a material portion
of the assets of ASCOR, or (iii) any equity or convertible  debt  transaction or

more than 20% of the aggregate voting power of ASCOR's  outstanding  securities,
other than in each case the  transactions  contemplated by this  Agreement.  For
purposes  of  the  foregoing  definition,  one  person  shall  be  deemed  to be
affiliated with a second person if such first person controls,  is controlled by
or is under common  control with the second  person,  and control,  for purposes
hereof,  shall be deemed to exist only in the event there exists ownership of or
the  right  to  vote,  in  either  case  directly  or   indirectly,   securities
representing  more  than  50% of  the  aggregate  voting  power  of an  entity's
outstanding securities.

         SECTION 5.05  MAINTENANCE OF BUSINESS.  ASCOR will use its best efforts
to carry on its  business,  keep  available  the  services of its  officers  and
employees and preserve its relationships with those of its customers, suppliers,
licensors and others having business  relationships with it that are material to
its  business  in  substantially  the same  manner  as it has  prior to the date
hereof.  If ASCOR becomes aware of a material  deterioration  or facts which are
likely  to result  in a  material  deterioration  in the  relationship  with any
material customer,  supplier,  licensor or others having business  relationships
with it,  it will  promptly  bring  such  information  to the  attention  of the
Giga-tronics in writing.

         SECTION 5.06 COMPLIANCE WITH OBLIGATIONS.  Prior to the Effective Date,
ASCOR shall comply with (i) all  applicable  federal,  state,  local and foreign
laws,  rules and  regulations,  (ii) all material  agreements  and  obligations,
including its Articles of Incorporation  and Bylaws, by which it, its properties
or its assets may be bound, and (iii) all decrees,  orders, writs,  injunctions,
judgments,   statutes,  rules  and  regulations  applicable  to  ASCOR  and  its
properties or assets.

         SECTION 5.07 NOTICES OF CERTAIN  EVENTS.  ASCOR shall,  upon  obtaining
knowledge of any of the following, promptly notify Giga-tronics of:

alleging  that the consent of such  person is or may be  required in  connection

judicial proceedings  commenced or threatened against ASCOR which, if pending on
the date of this  Agreement,  would have been  required  to have been  disclosed
pursuant to Sections  3.10 or 3.20 or which  relate to the  consummation  of the
Merger.

         SECTION 5.08  CONFIDENTIALITY.  ASCOR agrees that for a period of three

operations of Giga-tronics  whether of a technical or commercial nature, nor (b)
use, or permit or assist, by acquiescence or otherwise, any person, association,
firm,  corporation  or other  entity to use,  directly or  indirectly,  any such
information  or data in any  manner  which  reasonably  would  be  deemed  to be
competitive  with  the  operations  of  Giga-tronics  excepting  only use of (i)

industry.

         SECTION 5.09  COMPLIANCE  WITH THE SECURITIES ACT. ASCOR shall prior to
15 days after  signing but in any event prior to mailing of the Proxy  Statement
cause each person who is an  "affiliate," as that term is used in paragraphs (c)
and  (d) of  Rule  145  under  the  Securities  Act,  of  ASCOR  to  deliver  to
Giga-tronics an Affiliates  Agreement in substantially  the form attached hereto
as Exhibit 5.09 (an "ASCOR Affiliates Agreement").

misleading  in any  material  respect  (other  than  an  event  so  affecting  a

         SECTION 8.01 CONDITIONS TO OBLIGATIONS OF GIGA-TRONICS  AND MERGER SUB.
The  obligations  of  Giga-tronics  and Merger Sub  hereunder are subject to the
fulfillment  or  satisfaction,  on and as of the Effective  Date, of each of the
following  conditions  (any one or more of which may be waived by  Giga-tronics,
but only in a writing signed by Giga-tronics):

                      (a)  Accuracy  of  Representations  and  Warranties.   The
representations  and warranties of ASCOR  contained in Article III shall be true
and accurate in all material  respects on and as of the Effective  Date with the
same force and effect as if they had been made on the Effective  Date (except to
the extent a  representation  or warranty speaks only as of an earlier date) and
ASCOR  shall have  provided  Giga-tronics  with a  certificate  executed  by the
President and the Chief  Financial  Officer of ASCOR,  dated as of the Effective
Date, to such effect; provided, however, that any inaccuracy of a representation
or warranty,  on the date hereof or on the Effective  Date,  shall not result in
the  non-satisfaction  of this Section  8.01(a)  unless any such  inaccuracy  or
inaccuracies,  either (i) individually or in the aggregate, represent a Material
Adverse Effect on ASCOR or (ii) are willful and  intentional  misrepresentations
of a material  matter that  constitute  common law fraud.  For  purposes of this
Agreement,  a "Material  Adverse  Effect," with respect to any person or entity,
means  a  material  adverse  effect  on  the  financial   condition,   business,
liabilities (including contingent  liabilities) or results of operations of such
person or entity and its

                                       30.
<PAGE>   149
subsidiaries,  taken as a whole;  and  "Material  Adverse  Change"  shall mean a
change or a  development  involving  a  prospective  change  which  would have a
Material Adverse Effect.

                      (b)  Covenants.  ASCOR shall have  performed  and complied
with  all of its  covenants  contained  in  Articles  V and VII in all  material
respects on or before the  Effective  Date,  and  Giga-tronics  shall  receive a
certificate  to such  effect  signed by ASCOR's  President  and Chief  Financial
Officer.

                      (c) No Material  Adverse Change.  There shall have been no
Material Adverse Change in ASCOR since the ASCOR Balance Sheet Date.

                      (d)  Affiliates   Agreements.   Giga-tronics   shall  have
received  from each person or entity who may be deemed  pursuant to Section 5.09
to be an  affiliate  of ASCOR a duly  executed  Affiliates  Agreement,  and such
Affiliates Agreements shall remain in full force and effect.

                      (e)  Satisfactory  Completion  of  Due  Diligence  Review.
Giga-tronics  shall have  completed  its due  diligence  review of the business,
operations  and  financial  condition  of ASCOR by May 24,  1996 and such review
shall not have  revealed  any  facts or  circumstances  which in the  reasonable
judgment of Giga-tronics  could have a Material Adverse Effect on ASCOR. If such
due diligence review shall reveal facts or circumstances which in the reasonable
judgement  of  Giga-tronics  could  have a  Material  Adverse  Effect  on ASCOR,
Giga-tronics shall promptly notify ASCOR of its determination or shall be deemed
to have waived compliance with this condition.

                      (f) Pooling of Interests  Matters.  In the sole discretion
of Giga-tronics,  the Merger shall qualify for accounting treatment as a pooling
of interests in accordance with Accounting  Principles  Board Release No. 16. In
determining whether the Merger so qualifies Giga-tronics may consider the impact
on such  qualification  of ASCOR  Shares  which are voted  against the Merger or
which have abstained from voting with respect to the Merger.

                      (g)  Giga-tronics  Dissenters'  Rights.   Shareholders  of
Giga-tronics  shall  not have  perfected  dissenters'  rights  with  respect  to
Giga-tronics  Common  Stock  with  respect to five  percent  (5%) or more of the
Giga-tronics   Common  Stock   outstanding  on  the  date  of  the  Giga-tronics
Shareholder Meeting.

                      (h) ASCOR  Preferred  Stock.  As of the  Closing  Date all
shares of ASCOR  Preferred  Stock  outstanding  as of the date of this Agreement
shall (i) have remained outstanding (ii) shall have been tendered at the Closing
with instructions that such shares are to be exchanged at the Effective Time for
Giga-tronics  Common Stock in accordance with the terms of this  Agreement,  and
(iii) not have been  transferred  by the owners of such shares as of the date of

Effective Date, of

                                       31.

representations  and warranties of Giga-tronics set forth in Article IV shall be
true and accurate in all material  respects on and as of the Effective Date with
the same force and effect as if they had been made on the Effective Date (except
to the extent a representation or warranty speaks only as of an earlier date and
except for changes  contemplated by this Agreement) and Giga-tronics  shall have
provided  ASCOR  with a  certificate  executed  by the  President  and the Chief
Financial  Officer of  Giga-tronics,  dated as of the  Effective  Date,  to such
effect; provided,  however, that any inaccuracy of a representation or warranty,
on  the  date  hereof  or on  the  Effective  Date,  shall  not  result  in  the
non-satisfaction   of  this  Section  8.02(a)  unless  any  such  inaccuracy  or
inaccuracies,  either (i) individually or in the aggregate, represent a Material
Adverse   Effect  on   Giga-tronics   or  (ii)  are  willful   and   intentional
misrepresentations that constitute common law fraud of a material matter.

                      (b)  Covenants.  Giga-tronics  shall  have  performed  and
complied with all of its covenants contained in Section 2.03 and Articles VI and
VII in all material  respects on or before the Effective  Date,  and ASCOR shall
receive a  certificate  to such effect  signed by  Giga-tronics's  President and
Chief Financial Officer.

                      (c) No Material  Adverse Change.  There shall have been no
Material  Adverse Change in Giga-tronics  since the  Giga-tronics  Balance Sheet
Date.

         SECTION 8.03  CONDITIONS TO OBLIGATIONS  OF EACH PARTY.  The respective
obligations of ASCOR and Giga-tronics  hereunder are subject to the fulfillment,
on and as of the Effective Date, of each of the following conditions (any one or
more of which  may be waived by such  parties,  but only in a writing  signed by
such parties):

                      (a) Shareholder Approval. Each of ASCOR's shareholders and
Giga-tronics'  shareholders shall have duly approved this Agreement,  the Merger
Agreement and the Merger,  all in accordance with applicable laws and regulatory
requirements.

                      (b)   Tax-Free   Reorganization.   Each   of   ASCOR   and
Giga-tronics  shall have  received a written  opinion  from  Brobeck,  Phleger &
Harrison  LLP  ("Brobeck")  to the effect  that the  Merger  will  constitute  a
reorganization  within the  meaning of Section 368 of the Code,  which  opinions
shall be substantially  identical in form and substance.  In preparing ASCOR and
the Giga-tronics tax opinions, Brobeck may rely on (and to the extent reasonably
required,   the  parties  and  ASCOR's   shareholders   shall  make)  reasonable
representations related thereto.

                      (c)  Illegality  or Legal  Constraint.  No statute,  rule,
regulation,  executive order, decree, injunction or restraining order shall have
been enacted, promulgated or enforced (and not repealed, superseded or otherwise
made  inapplicable)  by any court or governmental  authority which prohibits the
consummation of the Merger (each party

                                       32.
<PAGE>   151
agreeing to use its  reasonable  best efforts to have any such order,  decree or
injunction lifted).

                      (d) Consents. All written consents,  assignments,  waivers
or authorizations ("Consents"), other than Governmental Authorizations, that are
required as a result of the Merger for the continuation in full force and effect
of any  material  contracts or leases of ASCOR or  Giga-tronics  shall have been
obtained,  other than those  Consents  the failure of which to obtain  would not
have a Material Adverse Effect on ASCOR or Giga-tronics.

                      (e)  Governmental  Authorizations.  There  shall have been
obtained  any  and  all  Governmental  Authorizations,  permits,  approvals  and
consents of securities or "blue sky"  commissions of any jurisdiction and of any
other  governmental  body or agency,  that may reasonably be deemed necessary so
that the  consummation of the Merger will be in compliance with applicable laws,
the  failure to comply  with  which  would  have a  Material  Adverse  Effect on
Giga-tronics,  ASCOR or the Surviving  Corporation or would be reasonably likely
to subject any of  Giga-tronics,  Merger Sub,  ASCOR or any of their  respective
directors or officers to substantial penalties or criminal liability.

                      (f)  HSR  Act.  The  waiting  period  (and  any  extension
thereof)  applicable to the  consummation  of the Merger under the HSR Act shall
have expired or been terminated.

                            TERMINATION OF AGREEMENT

         SECTION 9.01 TERMINATION.  This Agreement may be terminated at any time
prior to the  Effective  Time  whether  before  or  after  the  approval  by the
shareholders of ASCOR or Giga-tronics:

                              (i) by mutual  consent of the Boards of  Directors
         of Giga-tronics, Merger Sub and ASCOR;

                              (ii) by  either  Giga-tronics  and  Merger  Sub or
         ASCOR, if the requisite vote of the shareholders of Giga-tronics  shall
         not have been obtained or the written  consent of shareholders of ASCOR
         shall not be obtained by December 31, 1996;

                              (iii) by  Giga-tronics,  if it is not in  material
         breach of its  obligations  under  this  Agreement  and if the Board of
         Directors of ASCOR shall have:

                                       (A) withdrawn its  recommendation  of the
         Merger, or

                                       33.
<PAGE>   152
                                       (B)    recommended    or   approved   any
         acceptance by shareholders  of any Acquisition  Proposal (other than an
         Acquisition   Proposal  made  by   Giga-tronics   or  an  affiliate  of
         Giga-tronics); or

                              (iv) by ASCOR,  if it is not in material breach of
         its  obligations  under this Agreement and if the Board of Directors of
         Giga-tronics shall have:

                                       (A) withdrawn its  recommendation  of the
         Merger, or

                                       (B)    recommended    or   approved   any
         acceptance by shareholders  of any Acquisition  Proposal (other than an
         Acquisition Proposal made by ASCOR or an affiliate of ASCOR); or

                              (v)  by  either  Giga-tronics  and  Merger  Sub or
         ASCOR,   respectively,   (A)  if  there   has  been  a  breach  of  any
         representation  and  warranty  such that  Section  8.01(a) or  8.02(a),
         respectively,  cannot be satisfied or (B) if there has been the willful
         breach  on  the  part  of  ASCOR  or   Giga-tronics   and  Merger  Sub,
         respectively,  of any covenant or agreement contained in this Agreement
         such that Sections 8.01(b) or 8.02(b) cannot be satisfied,  and in both
         case (A) and case (B) such  breach has not been  promptly  cured  after
         notice to the breaching party; or

                              (vi) by Giga-tronics,  if the conditions contained
         in Section 8.02(f), (g) or (h) are not satisfied; or

                              (vii) by Giga-tronics,  if ASCOR shall have issued
         any ASCOR Securities between the date of this Agreement and the Closing
         Date without the prior consent of Giga-tronics; or

                              (viii) by either  Giga-tronics  and  Merger Sub or
         ASCOR,  respectively,  at any time after December 31, 1996,  unless the
         delay is caused by the failure of the terminating  party to fulfill its
         obligations hereunder.

         SECTION 9.02 EFFECT OF TERMINATION. In the event of termination of this
Agreement as provided above,  this Agreement  shall  forthwith  become void, and
there shall be no  liability on the part of either  Giga-tronics,  Merger Sub or
ASCOR,  except that each of the agreements  contained or referred to in Sections
5.08, 6.06 and 11.02 shall survive the termination  hereof;  provided,  however,
that each party  shall be  entitled  to any  remedies at law or in equity in the
event of a breach of this  Agreement by the other  party,  except as provided in
Sections 11.02(b) and (c).

<PAGE>   155
         SECTION 11.07 SEVERABILITY.  If any provision of this Agreement, or the
application  thereof,  shall for any  reason  or to any  extent  be  invalid  or
unenforceable, the remainder of this Agreement and application of such provision
to other persons or circumstances shall continue in full force and effect and in
no way be affected, impaired or invalidated.

         SECTION 11.08 ENTIRE AGREEMENT. This Agreement and the other agreements
and  instruments  referenced  herein  constitute  the entire  understanding  and
agreement of the parties with respect to the subject matter hereof and supersede
all prior and  contemporaneous  agreements  or  understandings,  inducements  or
conditions,  express or  implied,  written or oral,  between  the  parties  with

         SECTION 11.09 OTHER REMEDIES.  Except as otherwise provided herein, any
and all  remedies  herein  expressly  conferred  upon a party  shall  be  deemed

or prospectively) only by a writing signed by the party to be bound thereby. The

further approval.

         SECTION 11.11 NO WAIVER. The failure of any party to enforce any of the
provisions  hereof  shall not be  construed  to be a waiver of the right of such
party thereafter to enforce such provisions.

         SECTION 11.12 CONSTRUCTION OF AGREEMENT;  KNOWLEDGE.  A reference to an
Article,  Section or an  Exhibit  shall  mean an  Article  of, a Section  in, or

limit the  construction  of this Agreement which shall be considered as a whole.
The words "include," "includes" and "including" when used herein shall be deemed
in each case to be followed by the words "without  limitation."  For purposes of
this  Agreement,  "knowledge"  of any  party  shall  mean the  knowledge  of the
executive  officers of such party after such  officers  shall have made  inquiry
that is customary and appropriate  under the circumstances to which reference is

                      Manner And Basis Of Converting Shares

         4.01     At the Effective Time of the Merger:

                  (a)      Each share of AAC Stock which is outstanding
immediately prior to the Effective Time of the Merger shall be converted at the
Effective Time of the Merger into one share of ASCOR Common Stock.

                  (b)      Each share of ASCOR Common Stock, each share of ASCOR
Series A Preferred Stock, each share of ASCOR Series B Preferred Stock and each
share of ASCOR Series C Preferred Stock (except for shares, if any, which shall
then or thereafter constitute "dissenting shares" within the meaning of Section
1300 of the California General Corporations Law and those shares of AAC common
stock converted to shares of ASCOR Common Stock pursuant to Section 4.01(a)
above) which is outstanding immediately prior to the Effective Time of the

[__________________ FINAL NUMBER TO BE INSERTED AT CLOSING PURSUANT TO
CALCULATION CONTAINED IN REORGANIZATION AGREEMENT] shares (the "Exchange Ratio")
of Giga-tronics Common Stock.

         4.02     Giga-tronics shall not be required to issue or deliver any
fractional shares of Giga-tronics Giga-tronics Common Stock or any Giga-tronics
certificates

                                        3
<PAGE>   163
representing fractional shares of Giga-tronics Common Stock in connection with
any exchange of ASCOR certificates for Giga-tronics certificates; however,
Giga-tronics shall pay to each person who would otherwise be entitled to receive
a Giga-tronics certificate representing a fractional share of Giga-tronics
Common Stock an amount in cash (rounded to the nearest whole cent) equal to such
fraction multiplied by the closing sale price per share of Giga-tronics Common
Stock on the last business day on which Giga- tronics Common Stock is traded on
the NASD prior to the Effective Time.

         4.03     Immediately after the Effective Time of the Merger and after
surrender to Giga-tronics or such other party designated by Giga-tronics (the
"Exchange Agent") of any certificate which prior to the Effective Time of the
Merger shall have represented any ASCOR Shares, Giga-tronics shall cause to be
distributed to the person in whose name such certificate shall have been issued
a certificate registered in the name of such person representing the whole
shares of Giga-tronics Common Stock into which any shares previously represented
by the surrendered certificate shall have been converted at the Effective Time
of the Merger, along with the check representing the value of any fractional
share as determined in Section 4.02 above. Until surrendered to the Exchange
Agent, each certificate which immediately prior to the Effective Time of the
Merger shall have represented any ASCOR Share shall be deemed at and after the
Effective Time of the Merger to represent only the right to receive upon
surrender the certificate and payment contemplated above. Upon such surrender,
there shall be paid to the person in whose name the certificate representing
such shares of Giga-tronics Ordinary Shares shall be issued and without interest
any dividends which shall have become payable with respect to such shares of
Giga-tronics Common Stock between the Effective Time of the Merger and the time
of such surrender.

                                   ARTICLE V.

         5.01     This Merger Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         5.02     Notwithstanding approval of this Merger Agreement by the
shareholders of either of the Constituent Corporations, this Merger Agreement
shall terminate forthwith in the event that the Agreement and Plan of
Reorganization shall be terminated as therein provided.

         5.03     This Merger Agreement may be amended by the parties hereto at
any time before or after approval hereof by the shareholders of the Constituent
Corporations and Giga-tronics, but, after any such approval, no amendment shall
be made which would have a material adverse effect on the shareholders of either
of the

                                        4
<PAGE>   164
Constituent Corporations or Giga-tronics, or change any of the principal terms
of the Merger Agreement, without the further approval of such shareholders. This
Merger Agreement may not be amended except by an instrument in writing signed on
behalf of each of the parties hereto. Without limiting the foregoing, the
parties hereto acknowledge and agree that any modification of the manner or
basis of converting ASCOR Shares into Giga-tronics Common Stock shall require
further approval of the Board of Directors (or appropriate committee thereof
empowered to so act) of Giga-tronics and the shareholders of ASCOR.

                                  EXHIBIT 5.09

                       FORM OF ASCOR AFFILIATES AGREEMENT

                  THIS AFFILIATES AGREEMENT (the "Agreement") is entered into as
of this __ day of May, 1996 among GIGA-TRONICS, INC., a California corporation
("Giga- tronics"), the undersigned shareholder ("Shareholder") of ASCOR, INC., a
California corporation ("ASCOR"), ASCOR ACQUISITION CORP., a California
corporation and wholly owned subsidiary of Giga-tronics ("MERGER SUB") and
ASCOR.

                  This Agreement is entered into in connection with that certain
Agreement and Plan of Reorganization dated as of May __, 1996 (the
"Reorganization Agreement") among Giga-tronics, Merger Sub, and ASCOR. The
Reorganization Agreement provides for the merger (the "Merger") of Merger Sub
with and into ASCOR in a transaction in which issued and outstanding shares of
common stock, no par value, and preferred stock, no par value, of ASCOR (the
"ASCOR Stock") will be exchanged for shares of common stock, no par value of
Giga-tronics (the "Giga-tronics Stock") on the terms and conditions set forth in
the Reorganization Agreement. Capitalized terms used herein and not defined
herein shall have their defined meanings as set forth in the Reorganization
Agreement.

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual representations, warranties and covenants set forth herein, the parties
agree as follows:

                  1.       TAX AND ACCOUNTING TREATMENT. Shareholder understands
and agrees that it is intended that the Merger will be treated as a
"reorganization" for federal income tax purposes and as a "pooling of interests"
in accordance with generally accepted accounting principals and the applicable
General Rules and Regulations published by the Securities and Exchange
Commission (the "SEC"). Shareholder further understands and agrees that
Shareholder may be deemed to be an "Affiliate" of ASCOR within the meaning of
Rule 145 ("Rule 145") promulgated under the Securities Act of 1933, as amended
(the "Securities Act"), although nothing contained herein should be construed as
an admission of such fact.

                  2.       RELIANCE UPON REPRESENTATIONS, WARRANTIES AND
COVENANTS. Shareholder has been informed that the treatment of the Merger as a
reorganization for federal income tax purposes requires that a sufficient number
of former stockholders of ASCOR maintain a meaningful continuing equity
ownership interest in Giga-tronics after the Merger. Shareholder understands
that the representations, warranties and covenants of the Shareholder set forth
herein will be relied upon by Giga-tronics, ASCOR, and agrees that their
respective counsel and accounting firms and other stockholders of ASCOR shall be
entitled to rely thereon.

                                       1.
<PAGE>   168
                  3.       REPRESENTATIONS, WARRANTIES AND COVENANTS OF
SHAREHOLDER. Share- holder represents, warrants and covenants as follows:

                           (a)      Shareholder has full power and authority to
         execute this Agreement, to make the representations, warranties and
         covenants herein contained and to perform Shareholder's obligations
         hereunder.

                           (b)      Appendix A attached hereto sets forth all
         shares of ASCOR Stock owned by Shareholder, including all ASCOR Stock
         as to which Shareholder has sole or shared voting or investment power
         and all rights and options to acquire ASCOR Stock.

                           (c)      Shareholder will not sell, transfer,
         exchange, pledge, or otherwise dispose of, or make any offer or
         agreement relating to any of the foregoing with respect to, any shares
         of Giga-tronics Stock that Shareholder may acquire in connection with
         the Merger, or any securities that may be paid as a dividend or
         otherwise distributed thereon or with respect thereto or issued or
         delivered in exchange or substitution therefor (all such shares and
         other securities of Giga-tronics being herein sometimes collectively
         referred to as "Restricted Securities"), or any option, right or other
         interest with respect to any Restricted Securities, unless (i) such
         transaction is permitted pursuant to Rule 144 and 145(d) under the
         Securities Act, (ii) counsel representing Shareholder shall have
         advised Giga-tronics in a written opinion letter satisfactory to
         Giga-tronics and Giga-tronics's legal counsel, and upon which
         Giga-tronics and its legal counsel may rely, that no registration under
         the Securities Act would be required in connection with the proposed
         sale, transfer or other disposition, (iii) a registration statement
         under the Securities Act covering the Giga-tronics Stock proposed to be
         sold, transferred or otherwise disposed of, describing the manner and
         terms of the proposed sale, transfer or other disposition, and
         containing a current prospectus, shall have been filed with the SEC and
         made effective under the Securities Act, or (iv) an authorized
         representative of the SEC shall have rendered written advice to
         Shareholder (sought by Shareholder or counsel to Shareholder, with a
         copy thereof and all other related communications delivered to
         Giga-tronics) to the effect that the SEC would take no action, or that
         the staff of the SEC would not recommend that the SEC take action, with
         respect to the proposed disposition if consummated.

                           (d)      Notwithstanding any other provision of this
         Agreement to the contrary, Shareholder will not sell, transfer,
         exchange, pledge or otherwise dispose of, or in any other way reduce
         Shareholder's risk of ownership or investment in, or make any offer or
         agreement relating to any of the foregoing with respect to any ASCOR
         Stock or any rights, options or warrants to purchase ASCOR Stock, or
         any Restricted Securities or other securities of Giga-tronics (i)
         during the 30-day period immediately preceding the Effective Time of
         the Merger and (ii) until such time after the Effective Time of the
         Merger as Giga-tronics has publicly released a report

                                       2.
<PAGE>   169
         including the combined financial results of Giga-tronics and ASCOR for
         a period of at least 30 days of combined operations of Giga-tronics and
         ASCOR within the meaning of Accounting Series Release No. 130, as
         amended, of the SEC. Giga- tronics agrees to publish such financial
         results expeditiously in a manner consistent with its prior practices;
         provided that nothing contained herein shall obligate Giga- tronics to
         publish its financial results other than on a quarterly basis.

                           (e)      Shareholder has, and as of the Effective
         Time of the Merger will have, no plan or intention (a "Plan") to sell,
         transfer, exchange, pledge (other than in a pre-existing bona fide
         margin account) or otherwise dispose of (any of the foregoing, a
         "Sale"), more than fifty percent (50%) of the shares of Giga-tronics
         Stock that Shareholder may acquire in connection with the Merger, or
         any securities that may be paid as a dividend or otherwise distributed
         thereon or with respect thereto or issued or delivered in exchange or
         substitution therefor. Sale shall also be deemed to include a
         distribution by a partnership to its partners, or a corporation to its
         stockholders, or any other transaction which results in a reduction in
         the risk of ownership. Shareholder is not aware of, or participating
         in, any Plan on the part of ASCOR stockholders to engage in Sales of
         the shares of Giga-tronics Stock to be issued in the Merger such that
         the aggregate fair market value, as of the Effective Time of the
         Merger, of the shares subject to such Sales would exceed fifty percent
         (50%) of the aggregate fair market value of all shares of outstanding
         ASCOR Stock immediately prior to the Merger. For purposes of the
         preceding sentence, shares of ASCOR Stock (i) with respect to which
         dissenters' rights are exercised, (ii) which are exchanged for cash in
         lieu of fractional shares of Giga-tronics Stock or (iii) with respect
         to which a pre-Merger Sale occurs in a transaction that is in
         contemplation of, or related or pursuant to, the Merger or the
         Reorganization Agreement, shall be considered to be shares of ASCOR
         Stock that are exchanged for Giga-tronics Stock in the Merger and then
         disposed of pursuant to a Plan. If any of Shareholder's representations
         in this Section 3(e) ceases to be true at any time prior to the
         Effective Time of the Merger, Shareholder will deliver to each of ASCOR

                      AGREEMENT AND PLAN OF REORGANIZATION

                                  EXHIBIT 6.08

                    FORM OF GIGA-TRONICS AFFILIATES AGREEMENT

                  THIS AFFILIATES AGREEMENT (the "Agreement") is entered into as
of this __ day of May, 1996 among GIGA-TRONICS, INC., a California corporation
("Giga-tronics"), the undersigned shareholder ("Shareholder") of GIGA-TRONICS,
ASCOR ACQUISITION CORP., a California corporation and wholly owned subsidiary of
Giga-tronics ("MERGER SUB") and ASCOR, INC., a California corporation ("ASCOR").

                  This Agreement is entered into in connection with that certain
Agreement and Plan of Reorganization dated as of May __, 1996 (the
"Reorganization Agreement") among Giga-tronics, Merger Sub, and ASCOR. The
Reorganization Agreement provides for the merger (the "Merger") of Merger Sub
with and into ASCOR in a transaction in which issued and outstanding shares of
common stock, no par value, and preferred stock, no par value of ASCOR (the
"ASCOR Stock") will be exchanged for shares of common stock, no par value of
Giga-tronics (the "Giga-tronics Stock") on the terms and conditions set forth in
the Reorganization Agreement. Capitalized terms used herein and not defined
herein shall have their defined meanings as set forth in the Reorganization
Agreement.

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual representations, warranties and covenants set forth herein, the parties
agree as follows:

                  1.       TAX AND ACCOUNTING TREATMENT. Shareholder understands
and agrees that it is intended that the Merger will be treated as a
"reorganization" for federal income tax purposes and as a "pooling of interests"
in accordance with generally accepted accounting principals and the applicable
General Rules and Regulations published by the Securities and Exchange
Commission (the "SEC"). Shareholder further understands and agrees that
Shareholder may be deemed to be an "Affiliate" of Giga-tronics within the
meaning of Rule 145 ("Rule 145") promulgated under the Securities Act of 1933,
as amended (the "Securities Act"), although nothing contained herein should be
construed as an admission of such fact.

                  2.       RELIANCE UPON REPRESENTATIONS, WARRANTIES AND
COVENANTS. Shareholder has been informed that the treatment of the Merger as a
reorganization for federal income tax purposes requires that a sufficient number
of shareholders of Giga-tronics maintain a meaningful continuing equity
ownership interest in Giga-tronics after the Merger. Shareholder understands
that the representations, warranties and covenants of the Shareholder set forth
herein will be relied upon by Giga-tronics, ASCOR, and agrees that their
respective counsel and accounting firms and other shareholders of ASCOR shall be
entitled to rely thereon.

                                       1.
<PAGE>   175
                  3.       REPRESENTATIONS, WARRANTIES AND COVENANTS OF
SHAREHOLDER. Shareholder represents, warrants and covenants as follows:

                           (a)      Shareholder has full power and authority to
         execute this Agreement, to make the representations, warranties and
         covenants herein contained and to perform Shareholder's obligations
         hereunder.

                           (b)      Appendix A attached hereto sets forth all
         shares of Giga-tronics stock owned by Shareholder, including all
         Giga-tronics stock as to which Shareholder has sole or shared voting or
         investment power and all rights and options to acquire Giga-tronics
         stock.

                           (c)      Shareholder will not sell, transfer,
         exchange, pledge, or otherwise dispose of, or make any offer or
         agreement relating to any of the foregoing with respect to, any shares
         of Giga-tronics Stock that Shareholder may acquire in connection with
         the Merger, or any securities that may be paid as a dividend or
         otherwise distributed thereon or with respect thereto or issued or
         delivered in exchange or substitution therefor (all such shares and
         other securities of Giga-tronics being herein sometimes collectively
         referred to as "Restricted Securities"), or any option, right or other
         interest with respect to any Restricted Securities, unless (i) such
         transaction is permitted pursuant to Rule 144 and 145(d) under the
         Securities Act, (ii) counsel representing Shareholder shall have
         advised Giga-tronics in a written opinion letter satisfactory to
         Giga-tronics and Giga-tronics's legal counsel, and upon which
         Giga-tronics and its legal counsel may rely, that no registration under
         the Securities Act would be required in connection with the proposed
         sale, transfer or other disposition, (iii) a registration statement
         under the Securities Act covering the Giga-tronics Stock proposed to be
         sold, transferred or otherwise disposed of, describing the manner and
         terms of the proposed sale, transfer or other disposition, and
         containing a current prospectus, shall have been filed with the SEC and
         made effective under the Securities Act, or (iv) an authorized
         representative of the SEC shall have rendered written advice to
         Shareholder (sought by Shareholder or counsel to Shareholder, with a
         copy thereof and all other related communications delivered to
         Giga-tronics) to the effect that the SEC would take no action, or that
         the staff of the SEC would not recommend that the SEC take action, with
         respect to the proposed disposition if consummated.

                           (d)      Notwithstanding any other provision of this
         Agreement to the contrary, Shareholder will not sell, transfer,
         exchange, pledge or otherwise dispose of, or in any other way reduce
         Shareholder's risk of ownership or investment in, or make any offer or
         agreement relating to any of the foregoing with respect to any
         Giga-tronics stock or any rights, options or warrants to purchase
         Giga-tronics stock, or other securities of Giga-tronics (i) during the
         30-day period immediately preceding the Effective Time of the Merger
         and (ii) until such time after the Effective Time of the Merger as
         Giga-tronics has publicly released a report including the combined

                                       2.
<PAGE>   176
         financial results of Giga-tronics and ASCOR for a period of at least 30
         days of combined operations of Giga-tronics and ASCOR within the
         meaning of Accounting Series Release No. 130, as amended, of the SEC.
         Giga-tronics agrees to publish such financial results expeditiously in
         a manner consistent with its prior practices; provided that nothing
         contained herein shall obligate Giga-tronics to publish its financial
         results other than on a quarterly basis.

                           (e)      Shareholder has, and as of the Effective
         Time of the Merger will have, no plan or intention (a "Plan") to sell,
         transfer, exchange, pledge (other than in a pre-existing bona fide
         margin account) or otherwise dispose of (any of the foregoing, a
         "Sale"), more than fifty percent (50%) of the shares of Giga-tronics
         Stock that Shareholder may acquire in connection with the Merger, or
         any securities that may be paid as a dividend or otherwise distributed
         thereon or with respect thereto or issued or delivered in exchange or
         substitution therefor. Sale shall also be deemed to include a
         distribution by a partnership to its partners, or a corporation to its
         shareholders, or any other transaction which results in a reduction in
         the risk of ownership. Shareholder is not aware of, or participating
         in, any Plan on the part of ASCOR shareholders to engage in Sales of
         the shares of Giga-tronics Stock to be issued in the Merger such that
         the aggregate fair market value, as of the Effective Time of the
         Merger, of the shares subject to such Sales would exceed fifty percent
         (50%) of the aggregate fair market value of all shares of outstanding
         ASCOR Stock immediately prior to the Merger. For purposes of the
         preceding sentence, shares of ASCOR Stock (i) with respect to which
         dissenters' rights are exercised, (ii) which are exchanged for cash in
         lieu of fractional shares of Giga-tronics Stock or (iii) with respect
         to which a pre-Merger Sale occurs in a transaction that is in
         contemplation of, or related or pursuant to, the Merger or the
         Reorganization Agreement, shall be considered to be shares of ASCOR
         Stock that are exchanged for Giga-tronics Stock in the Merger and then
         disposed of pursuant to a Plan. If any of Shareholder's representations
         in this Section 3(e) ceases to be true at any time prior to the
         Effective Time of the Merger, Shareholder will deliver to each of ASCOR
         and Giga- tronics, prior to the Effective Time of the Merger, a written
         statement to that effect, signed by Shareholder.

                  4.       RULE 144 AND 145. From and after the Effective Time
of the Merger and for so long as is necessary in order to permit Shareholder to
sell the Giga-tronics Stock held by and pursuant to Rule 144 under the
Securities Act, Giga-tronics will use its best efforts to file on a timely basis
all reports required to be filed by it pursuant to Section 13 of the Securities
Exchange Act of 1934, as amended, referred to in paragraph (c)(1) of Rule 144
under the Securities Act, in order to permit Shareholder to sell the
Giga-tronics Stock held by it pursuant to the terms and conditions of Rule 144.
Shareholder understands that, except as set forth in the Reorganization
Agreement and the Registration Rights Agreement, Giga-tronics is under no
obligation to register the sale, transfer or other disposition of any Restricted
Securities by or on behalf of Shareholder or to take any other action necessary
in order to make compliance with an exemption from registration available.

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement") is entered into as
of the ____ day of [June] 1996, by and among Giga-tronics, Inc., a California
corporation (the "Company") and the shareholders who are former shareholders
(the "Ascor Shareholders") of Ascor, Inc., a California corporation ("Ascor") .

                                    RECITALS

                  WHEREAS, as of the date hereof each of the Ascor Shareholders
owns the number of shares of the Company's Common Stock (the "Common Stock") set
forth opposite its name on Exhibit A hereto;

                  WHEREAS, the Ascor Shareholders received such Company Common
Stock pursuant to the Merger of Ascor with Ascor Acquisition Corporation, a
wholly-owned subsidiary of the Company pursuant to the terms of that certain
Agreement and Plan of Reorganization dated as of May ___, 1996 (the "Merger
Agreement") by and among the Company Ascor Acquisition Corp. And Ascor; and

                  WHEREAS, the execution of this Agreement by the Company is a
condition to the obligations of Ascor under the Merger Agreement and the Company
has agreed to execute this Agreement and grant to the Ascor Shareholders the
rights contained herein in order to fulfill such condition.

                  NOW, THEREFORE, the parties agree as follows:

SECTION 1. Amendment

         1.1      Amendment and Waiver. Except as expressly provided in this
Agreement, neither this Agreement nor any term hereof may be amended, waived,
discharged or terminated other than upon the written consent of all of (i) the
Company and (ii) the Holders of at least a majority of the Registrable
Securities. Any amendment or waiver effected in accordance with this paragraph
shall be binding upon each Holder of Registrable Securities and the Company. In
the event that an underwriting agreement is entered into between the Company and
any Holder, and such underwriting agreement contains terms differing from this
Agreement as to any such Holder, the terms of such underwriting agreement shall
govern.

         1.2      Effect of Amendment or Waiver. Without limiting the provisions
of Section 1.1 hereof, the Investors and their successors and assigns
acknowledge that by the operation of Section 3.7 hereof the holders of a
majority of the outstanding Registrable Securities, acting in conjunction with
the Company, will have the right and power to diminish or eliminate all rights
pursuant to this Agreement

                                       1.
<PAGE>   184
SECTION 2. Registration Rights

         2.1      Definitions. As used in this Agreement:

                  (a)      The terms "register," "registered," and
"registration" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act of 1933, as amended
(the "Securities Act") and the subsequent declaration or ordering of the
effectiveness of such registration statement.

                  (b)      The term "Registrable Securities" means:

                           (i)      the shares of Common Stock issuable to the
Ascor Shareholder upon consummation of the Merger; and

                           (ii)     any other shares of Common Stock issued as
(or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to,
or in exchange for or in replacement of, the Registrable Securities, excluding
in all cases, however, any Registrable Securities sold by a person in a
transaction in which his or her rights under this Agreement are not assigned;
provided, however, that Common Stock or other securities shall only be treated
as Registrable Securities if and so long as they have not been (A) sold to or
through a broker or dealer or underwriter in a public distribution or a public
securities transaction, or (B) sold, assigned or otherwise transferred in a
transaction in which the rights under this Section 2 have not been assigned in
accordance with Section 2.13.

                  (c)      The number of shares of "Registrable Securities then
outstanding" shall be determined by the number of shares of Common Stock
outstanding which are, and the number of shares of Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities.

                  (d)      The term "Holder" means any person owning of record
Registrable Securities who acquired such Registrable Securities in a transaction
or series of transactions not involving any registered public offering.

                  (e)      Capitalized terms used but not defined in this
Agreement shall have the meanings attributed to them in the Merger Agreement.

         2.2      Requested Registration.

                  (a)      If the Company shall receive at any time after
results covering at least thirty (30) days of combined operations of the Company
and Ascor have been published by the Company in the form of a quarterly earnings
report, an effective registration statement filed with the Securities and
Exchange Commission (the "Commission"), a report to the Commission on Form 10-K,
10-Q or 8-K, or any other

                                       2.
<PAGE>   185
public filing or announcement which includes the combined results of operation,
a written request from one or more Holders that the Company file a registration
statement under the Securities Act covering the registration of at least 200,000
Registrable Securities (as such number may be adjusted from time to time for
stock dividends, splits or other changes in the capitalization of the Company)
or a lesser number if the anticipated aggregate offering price, net of
underwriting discounts and commissions, would exceed $1,000,000, then the
Company shall, within ten (10) days of the receipt thereof, give written notice
of such request to all Holders and shall, subject to the limitations of
subsection 2.2(b), use all reasonable efforts to file and cause the
effectiveness of, within 90 days of the receipt of such request, the
registration under the Securities Act of all Registrable Securities which the
Holders request to be registered within twenty (20) days of the mailing of such
notice by the Company in accordance with Section 3.5.

                  (b)      If the Holders initiating the registration request
hereunder ("Initiating Holders") intend to distribute the Registrable Securities
covered by their request by means of an underwriting, they shall so advise the
Company as a part of their request made pursuant to this Section 2.2 and the
Company shall include such information in the written notice referred to in
subsection 2.2(a). The underwriter will be selected by the Company and shall be
reasonably acceptable to a majority in interest of the Initiating Holders;
provided, however, that if the Company is not also intending to sell any shares
under such Registration Statement, then the underwriter will be selected by a
majority in interest of the Initiating Holders and shall be reasonably
acceptable to the Company. In such event, the right of any Holder to include his
Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall (together with the Company as provided in subsection
2.4(e)) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting. Notwithstanding any
other provision of this Section 2.2, if the underwriter advises the Initiating
Holders in writing that marketing factors require a limitation of the number of
shares to be underwritten, then the Initiating Holders shall so advise all
Holders of Registrable Securities which would otherwise be underwritten pursuant
hereto, and the number of shares of Registrable Securities that may be included
in the underwriting shall be allocated among all Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder.

                  (c)      The Company is obligated to effect only one (1) such
registration pursuant to this Section 2.2. The Company shall be obligated to
maintain the effectiveness of any registration statement filed pursuant to this
Section 2.2 for no more than 180 days subsequent to declaration of its
effectiveness by the Commission.

                                       3.
<PAGE>   186
                  (d)      Notwithstanding the foregoing, if the Company shall
furnish to Holders requesting a registration statement pursuant to this Section
2.2, a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its shareholders for such registration
statement to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
for a period of not more than one hundred and twenty (120) days after receipt of
the request of the Initiating Holders; provided, however, that the Company may
not utilize this right more than twice in total.

         2.3      Company Registration. If (but without any obligation to do so
under this Agreement) the Company proposes to register (including for this
purpose a registration effected by the Company for shareholders other than the
Holders) any of its Common Stock or other securities under the Securities Act in
connection with the public offering of such securities solely for cash (other
than a registration relating either to the sale of securities to participants in
a Company stock option, stock purchase or similar plan or to an SEC Rule 145
transaction, or a registration on any form which does not include substantially
the same information as would be required to be included in a registration
statement covering the sale of the Registrable Securities), the Company shall,
at such time, promptly give each Holder written notice of such registration.
Upon the written request of each Holder given within twenty (20) days after
mailing of such notice by the Company in accordance with Section 3.5, the
Company shall, subject to the provisions of Section 2.8, cause to be registered
under the Securities Act all of the Registrable Securities that each such Holder
has requested to be registered.

         2.4      Obligations of the Company. Whenever required under this
Section 2 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                  (a)      Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its best efforts
to cause such registration statement to become effective, and, upon the request
of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective for up to one hundred
eighty (180) days.

                  (b)      Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                  (c)      Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                                       4.
<PAGE>   187
                  (d)      Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or, except as required under
the Securities Act, to file a general consent to service of process in any such
states or jurisdictions.

                  (e)      In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                  (f)      Notify each Holder of Registrable Securities covered
by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

                  (g)      Cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange or automated
quotation system on which similar securities issued by the Company are then
listed.

         2.5      Furnish Information.

                  (a)      It shall be a condition precedent to the obligations
of the Company to take any action pursuant to this Section 2 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish to
the Company such information regarding itself, the Registrable Securities held
by it, and the intended method of disposition of such securities as shall be
required to effect the registration of such Holder's Registrable Securities.

                  (b)      The Company shall have no obligation with respect to
any registration requested pursuant to Section 2.2 or Section 2.12 if, due to
the failure of sufficient Holders to satisfy the condition precedent set forth
in subsection 2.5(a), the number of shares or the anticipated aggregate offering
price of the Registrable Securities to be included in the registration does not
equal or exceed the number of shares or the anticipated aggregate offering price
required to originally trigger the Company's obligation to initiate such
registration as specified in subsection 2.2(a) or subsection 2.12(b)(2),
whichever is applicable.

         2.6      Expenses of Demand Registration. All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or

                                       5.
<PAGE>   188
qualifications pursuant to Section 2.2, including (without limitation), all
registration, filing and qualification fees, printers and accounting fees, fees
and disbursements of counsel for the Company, and the reasonable fees and
disbursements of up to $25,000 for one (but only one) counsel for the selling
Holders shall be borne by the Company.

         2.7      Expenses of Company Registration. The Company shall bear and
pay all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 2.3 for each Holder (which right may be assigned as provided
in Section 2.13), including (without limitation) all registration, filing, and
qualification fees, printers and accounting fees relating or apportionable
thereto, but excluding the fees and disbursements of counsel for the selling
Holders and underwriting discounts and commissions relating to Registrable
Securities.

         2.8      Underwriting Requirements. In connection with any offering
involving an underwriting of shares being issued by the Company, the Company
shall not be required under Section 2.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it, and then
only in such quantity as will not, in the opinion of the underwriters,
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters reasonably believe compatible with the success
of the offering, then the Company shall be required to include in the offering
only that number of such securities, including Registrable Securities, which the
underwriters believe will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling shareholders
according to the total amount of securities entitled to be included therein
owned by each selling shareholder or in such other proportions as shall mutually
be agreed to by such selling shareholders, provided that the number of shares of
Registrable Securities to be included in any such offering shall not be reduced
unless all other securities held by persons other than the Holders or the
Company are first entirely excluded from the underwriting); but in no event
shall the amount of securities of the selling Holders included in the offering
be reduced below twenty percent (20%) of the total amount of securities included
in such offering. For purposes of the preceding parenthetical concerning
apportionment, for any selling shareholder which is a holder of Registrable
Securities and which is a partnership or corporation, the partners, retired
partners and shareholders of such holder, or the estates and family members of
any such partners and retired partners and any trusts for the benefit of any of
the foregoing persons shall be deemed to be a single "selling shareholder," and
any pro rata reduction with respect to such "selling shareholder" shall be based
upon the aggregate amount of shares carrying registration rights owned by all
entities and individuals included in such "selling shareholder," as defined in
this sentence.

         2.9      Delay of Registration. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 2.

         2.10     Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 2:

                  (a)      To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, any underwriter (as defined in the
Securities Act) for such Holder and each person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Securities
Exchange Act of 1934, as amended (the "1934 Act"), against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Securities Act, the 1934 Act or other federal or state law, insofar as
such losses, claims, damages, or liabilities (or actions in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the 1934 Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the 1934 Act or any state securities law; and the Company will pay as incurred
to each such Holder, underwriter or controlling person, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this subsection 2.10(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld), nor shall the Company be
liable in any such case for any such loss, claim, damage, liability, or action
to the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by any such Holder, underwriter or
controlling person.

                  (b)      To the extent permitted by law, each selling Holder
will indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Securities Act, any underwriter,
any other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Securities Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation, in
each case to

                                       7.
<PAGE>   190
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by such Holder expressly
for use in connection with such registration; and each such Holder will pay, as
incurred, any legal or other expenses reasonably incurred by any person intended
to be indemnified pursuant to this subsection 2.10(b), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
2.10(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Holder, which consent shall not be unreasonably withheld.

                  (c)      Promptly after receipt by an indemnified party under
this Section 2.10 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 2.10, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 2.10, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section
2.10.

                  (d)      No indemnifying party, in the defense of any claim
arising out of a Violation shall, except with the consent of each indemnified
party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect
to such claim or litigation and, in the event the terms of such judgment or
settlement include any term other than the payment by the indemnifying party of
money damages, the indemnifying party shall not so consent or enter into such a
settlement without the consent of each indemnified party (which will not be
unreasonably withheld) whether or not the terms thereof include such a release.

                  (e)      The obligations of the Company and Holders under this
Section 2.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 2, and otherwise.

                                       8.
<PAGE>   191
                  (f)      Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

         2.11     Reports Under Securities Exchange Act of 1934. With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration the Company agrees to file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the 1934 Act.

         2.12     Assignment of Registration Rights. The rights to cause the
Company to register Registrable Securities pursuant to this Section 2 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who, after such assignment or transfer, holds (i) at
least 1% of the Registrable Securities then outstanding (subject to appropriate
adjustment for stock splits, stock dividends, combinations and other
recapitalizations), or (ii) all of the shares of Registrable Securities held by
such Holder, provided that, within a reasonable time after such transfer, the
Company is furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Securities Act. For the purposes of determining the number
of shares of Registrable Securities held by a transferee or assignee, the
holdings of transferees and assignees of a partnership who are partners or
retired partners of such partnership (including spouses and ancestors, lineal
descendants and siblings of such partners or spouses who acquire Registrable
Securities by gift, will or intestate succession) shall be aggregated together
and with the partnership; provided that all assignees and transferees who would
not qualify individually for assignment of registration rights shall have a
single attorney-in-fact for the purpose of exercising any rights, receiving
notices or taking any action under this Section 2.

         2.13     Limitations on Subsequent Registration Rights. From and after
the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of a majority of the outstanding Registrable Securities,
enter into any agreement with any holder or prospective holder of any securities
of the Company which would allow such holder or prospective holder (a) to
include such securities in any registration filed under Section 2.2 hereof,
unless under the terms of such agreement, such holder or prospective holder may
include such securities in any such registration only to the extent that the
inclusion of his securities will not reduce the amount of the Registrable
Securities of the Holders which is included or (b) to make a demand registration
which could result in such registration statement being declared effective prior
to the earlier of

                                       9.
<PAGE>   192
the date set forth in subsection 2.2(a) or within one hundred twenty (120) days
of the effective date of any registration effected pursuant to Section 2.2.

         2.14     Termination of Registration Rights. No Holder shall be
entitled to exercise any right provided for in this Section 2:

                  (a)      if the Registrable Securities were issued by
Giga-tronics to the Holder pursuant to a registration statement filed with the
SEC; or

                  (b)      at and after such time as such Holder holds
Registrable Securities equal to 1% or less of the outstanding stock of the
Company (calculated on an as-converted basis) and is able to dispose of all the
Registrable Securities held by such Holder under Rule 144 during any 90-day
period.

SECTION 3. Miscellaneous

         3.1      Assignment. Subject to the provisions of Section 2.13 hereof,

binding upon the respective successors and assigns of the parties hereto.

         3.2      Third Parties. Nothing in this Agreement, express or implied,
is intended to confer upon any party, other than the parties hereto, and their
respective successors and assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement, except as expressly provided
herein.

         3.3      Governing Law. This Agreement shall be governed by and
construed under the laws of the State of California in the United States of
America as applied to agreements among California residents entered into and to
be performed entirely within California.

         3.4      Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         3.5      Notices. Any notice or communication required or permitted by
this Agreement shall be deemed sufficiently given if in writing and, if
delivered personally, when it is delivered or, if delivered in another manner,
the earlier of when it is actually received by the party to whom it is directed
or when the period set forth below expires (whether or not it is actually
received):

                  A.       if deposited with the U.S. Postal Service, postage
prepaid, and addressed to the party to receive it as set forth below their
signatures, 48 hours after such deposit as registered or certified mail; or

                                       10.
<PAGE>   193

service in general usage for delivery to the address of the party to receive it
as set forth next below their signatures, 24 hours after the delivery time
promised by the delivery service.

         3.6      Severability. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, portions of such provisions, or
such provisions in their entirety, to the extent necessary, shall be severed
from this Agreement, and the balance of this Agreement shall be enforceable in
accordance with its terms.

         3.7      Rights of Holders. Each holder of Registrable Securities shall
have the absolute right to exercise or refrain from exercising any right or
rights that such holder may have by reason of this Agreement, including, without
limitation, the right to consent to the waiver or modification of any obligation
under this Agreement, and such holder shall not incur any liability to any other
holder of any securities of the Company as a result of exercising or refraining
from exercising any such right or rights.

         3.8      Delays or Omissions. No delay or omission to exercise any
right, power or remedy accruing to any party to this Agreement, upon any breach
or default of the other party, shall impair any such right, power or remedy of
such non-breaching party nor shall it be construed to be a waiver of any such
breach or default, or an acquiescence therein, or of or in any similar breach or
default thereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or
thereafter occurring. Any waiver, permit, consent or approval of any kind or
character on the part of any party of any breach or default under this
Agreement, or any waiver on the part of any party of any provisions or
conditions of this Agreement, must be made in writing and shall be effective
only to the extent specifically set forth in such writing. All remedies, either
under this Agreement, or by law or otherwise afforded to any holder, shall be
cumulative and not alternative.

necessary to enforce or interpret the terms of this Agreement, the prevailing
party shall be entitled to reasonable attorney's fees, costs and necessary
disbursements in addition to any other relief to which such party may be
entitled.

Board of Directors
Giga-tronics Incorporated
4650 Norris Canyon Road
San Ramon, CA  94583

Dear Sirs:

         You have requested our opinion as to the fairness from a financial
point of view to Giga-tronics Incorporated ("Giga-tronics" or the "Company") of
the Exchange Ratio (defined below) to be applied in connection with the proposed
merger of Giga-tronics and ASCOR Incorporated ("ASCOR") (the "Merger").
Giga-tronics and ASCOR have entered into an Agreement and Plan of Merger
("Merger Agreement") pursuant to which a newly created wholly owned subsidiary
of the Company would be merged into ASCOR, whereby ASCOR would continue to
operate as a wholly owned subsidiary of the Company, and each share of ASCOR
common stock would be converted into the right to receive Giga-tronics common
stock based on the quotient of (i) 724,986 shares of Giga-tronics common stock,
divided by (ii) the total number of ASCOR shares outstanding at the time the
Merger shall become effective, which is expected to be approximately 14,500,000
shares. The quotient based on 14,500,000 ASCOR shares outstanding would be
 .0500, and will change less than 1/100th based on the actual number of ASCOR
shares outstanding when the Merger becomes effective. The terms and conditions
of the Merger are set forth in more detail in the Giga-tronics proxy statement
dated May 2, 1996 ("Proxy Statement").

         In arriving at our opinion, we: (1) reviewed the Merger Agreement and
the Proxy Statement dated May 2, 1996 and such other information that was
publicly available or was furnished to us by the Company or ASCOR which we
believe to be relevant to our inquiry, (2) reviewed financial and operating
information with respect to the business operations and prospects of the Company
and ASCOR furnished to us by the Company and ASCOR, (3) prepared a discounted
cash flow analysis of ASCOR, (4) considered the historical stock prices and
trading volumes of the common stock of the Company from calendar 1993 to the
present, and (5) reviewed the prices and premiums paid in other business
combinations. In addition, Wood, Warren & Co. held discussions with senior
management of Giga-tronics and ASCOR regarding the strategic rationale for, and
benefits of, the Merger and the past and current business operations, financial
condition and future prospects of the respective companies on a stand alone
basis and as combined in the Merger, and undertook such other financial
analyses and investigations as we deemed appropriate for purposes of this
opinion.

         In rendering our opinion, we have relied upon and assumed, without
independent verification, the accuracy, completeness and fairness of all the
financial and other information that was available to us from public sources,
that was provided to us by the Company and ASCOR or that was otherwise reviewed
by us. We are not qualified to and did not evaluate the technical capabilities
of ASCOR's products or services. We have not

                                      E-1
<PAGE>   200
assumed any responsibility for making any independent evaluation of the assets
or liabilities of the Company or ASCOR or for making any independent
verification of any of the information supplied to or reviewed by us.

         Our opinion is necessarily based on economic, market, financial and
other conditions as they exist on, and on the information made available to us
as of, the date of this letter. Our opinion does not constitute a recommendation
to any shareholder as to how such shareholder should vote on the proposed
Merger. Our opinion does not address the underlying business decision of the
Company to enter into the Merger.

         We are expressing no opinion as to what the value of Giga-tronics
common stock will actually be when issued pursuant to the Merger or the prices
at which the common stock will actually trade at any time.

         Wood, Warren & Co., as part of its investment banking services, is
regularly engaged in the valuation of businesses and securities in connection
with mergers, acquisitions, private placements and valuations for corporate and
other purposes.

         Based upon the foregoing and such factors as we deem relevant, we are
of the opinion that the Exchange Ratio to be applied in the Merger is fair to
the Company from a financial point of view.

                                                    Very truly yours,



                                                    Wood, Warren & Co.

                           FINANCIAL ADVISOR ANALYSIS
                               FOR OPINION LETTER

         Giga-tronics engaged Wood, Warren & Co. to render an opinion as to the
fairness from a financial point of view to Giga-tronics of the Exchange Ratio
used in connection with the Merger. Wood, Warren & Co. rendered its written
opinion on May 2, 1996 to the Board of Directors of Giga-tronics that, as of
such date, the Exchange Ratio is fair from a financial point of view. Wood,
Warren & Co.'s opinion is directed only to the financial terms of the Merger
Agreement and does not constitute a recommendation to any stockholder of
Giga-tronics as to how such stockholder should vote at the Giga-tronics Special
Meeting. A copy of Wood, Warren & Co.'s opinion dated May 2, 1996 and the
procedures followed by Wood, Warren & Co., is attached hereto as Annex E pages
E-1 and E-2, and the summary of the complete opinion set forth in this Joint
Proxy Statement is qualified in its entirety by reference to the opinion.
Giga-tronics stockholders are advised to read the opinion in its entirety. No
limitations were placed on Wood, Warren & Co. by the Board of Directors of
Giga-tronics with respect to the investigation made or the procedures followed
in preparing and rendering its opinion.

         In arriving at its opinion, Wood, Warren & Co.: (i) reviewed the Merger
Agreement and the Proxy Statement dated May 2, 1996 and such other information
that was publicly available or was furnished to it by the Company or ASCOR, (ii)
reviewed financial statements for the five years ending March 30, 1996 and other
financial information, including forecasts, and operating data of Giga-tronics
and ASCOR furnished to Wood, Warren & Co. by the companies, (iii) considered the
historical stock prices and trading volumes of the common stock of the Company,
(iv) reviewed the prices and premiums paid in other business combinations, (v)
and prepared a discounted cash flow analysis of ASCOR. In addition,  Wood,
Warren & Co. held discussions with senior management of Giga-tronics and ASCOR
regarding the strategic rationale for, and benefits of, the Merger and the past
and current business operations, financial condition and future prospects of the
respective companies on a stand alone basis and as combined in the Merger, and
undertook such other financial analyses as it deemed appropriate for purposes of
this opinion.

         The following paragraphs summarize the significant analyses performed
by Wood, Warren & Co. in arriving at its opinion. The information presented
below is based on the financial condition of the Company and ASCOR as of a date
or dates shortly before the date of its opinion (May 2, 1996). The closing price
of Giga-tronics common stock on May 2, 1996, as reported by NASDAQ National
Marketing System, was $8.25. Based on that price and the assumption that
Giga-tronics will issue the maximum 724,986 shares of its common stock in the
Merger, the enterprise value of ASCOR was approximately $5.6 million.

         Analysis of Selected Transactions Analysis. Wood, Warren & Co.
compared the proposed Merger with selected merger and acquisition transactions.
This analysis included 32 technology company transactions. In examining these
transactions, Wood, Warren & Co. analyzed certain income statement and balance
sheet parameters of the acquired company relative to the consideration offered.
Multiples analyzed included consideration offered to historical revenue, to
historical earnings before interest and taxes, to historical net income, and to
historical book value. Based on the analysis of the selected merger and
acquisition transactions, ASCOR's implied enterprise value ranged from
approximately $5.0 million to approximately $16.7 million.

                                      E-3
<PAGE>   202
         Discounted Cash Flow Analysis. Wood, Warren & Co. analyzed the
theoretical valuation of ASCOR based on projections prepared by the managements
of Giga-tronics and ASCOR. To estimate the total present value of ASCOR's
business, Wood, Warren & Co. calculated a net present value of the free cash
flows for the fiscal years ended March 31, 1997 through 2001 using discount
rates ranging from 25% to 40%. The terminal value was based on multiples of 5.5
and 7.5 times projected earnings before interest and taxes for fiscal 2001.
Based on the discounted cash flow analysis, ASCOR's enterprise value ranged from
approximately $4.4 million to approximately $9.2 million.

         Pro Forma Analysis. Wood, Warren & Co. analyzed the pro forma impact of
the proposed Merger on Giga-tronics earnings per share. In conducting its
analysis, Wood, Warren & Co. relied upon the financial projections for the
fiscal years ending March, 1997 through 2001 provided by the management of
Giga-tronics and ASCOR, respectively. The analysis indicated that earnings per
share of the pro forma combined company would be higher in the first fiscal year
after the Merger and higher thereafter through fiscal 2001 than comparable
projections for Giga-tronics as a stand-alone company.

         Stock Trading History Analysis. Wood, Warren & Co. examined the trading
history in terms of both price and volume for periods of time ranging from six
months, one year, three years and five years. Wood, Warren & Co. noted that the
Giga-tronics' average price per share was $7.76, $7.65, $6.64, and $6.84,
respectively. In addition, Wood, Warren & Co. analyzed the volume of
Giga-tronics shares traded at different prices over the same time periods. Wood,
Warren & Co. noted that, for each period analyzed, approximately 48% to 64% of
the trading volume was at prices below the six month average price per share of
$7.76.

         Contribution Analysis. Wood, Warren & Co. reviewed the contribution of
each of Giga-tronics and ASCOR to certain financial statement categories of the
pro forma combined company, including revenue, gross profit, earnings before
interest and taxes, and net income. The review was made for the three years
ended March 30, 1996. This contribution analysis was then compared to the pro
forma ownership percentage of ASCOR's shareholders (approximately 22%) in the
pro forma combined company. For the year ended March 1996 and the average of the
three year period, ASCOR contributed approximately 19% and 17% to revenues, 19%
and 18% to gross profit, 52% and 102% (based on the two fiscal years 1994 and
1996 because Giga-tronics had a loss in 1995) to earnings before interest and
taxes, and 45% and 64% to net income.

         The preparation of a fairness opinion involves various determinations
as to the most appropriate and relevant quantitative and qualitative methods of
financial analyses and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. No company or transaction used in the above analysis is
closely comparable to Giga-tronics or ASCOR or the Merger. Accordingly, Wood,
Warren & Co., believes its analyses must be considered as a whole and that
considering any portion of such analyses and of the factors considered, without
considering all analyses and current factors, could create a misleading or
incomplete view of the process underlying the opinion. Any estimates contained
in these

                                      E-4
<PAGE>   203
analyses are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than as set
forth therein. In addition, analyses relating to the value of businesses do not
purport to be appraisals or to reflect the prices at which businesses actually
may be sold.

         In arriving at its opinion, Wood, Warren & Co. relied, without
independent verification, solely on the aforementioned information and
activities and did not obtain any independent appraisal of the properties or
assets of the Company or ASCOR. With respect to the financial projections
supplied to it, Wood, Warren & Co. assumed that such projections were reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of management of Giga-tronics and ASCOR as to the future financial
performance of the companies. Wood, Warren & Co.'s opinion is necessarily based
upon market, financial, economic and other conditions existing, and the
information available to it, as of the date of its opinion. It should be
understood that, although subsequent developments may affect its opinion, Wood,
Warren & Co. does not have any obligation to update, review or reaffirm its
opinion.

         Wood, Warren & Co. was formally engaged by the Board of Directors on
April 12, 1996 to render an opinion as to the fairness from a financial point of
view to Giga-tronics of the proposed Merger Exchange Ratio. Pursuant to the
engagement letter, Giga-tronics agreed to pay Wood, Warren & Co. a fee of
$29,950 of which $8,000 was to be paid upon the execution of the engagement
letter and $10,000 became due at the time the Proxy Statement was mailed to
stockholders and the balance is payable upon consummation of the Merger. The
obligation of the Company to pay such fees to Wood, Warren & Co. was not
contingent on whether the opinion of Wood, Warren & Co. was favorable or
unfavorable. In addition, the Company agreed to indemnify Wood, Warren & Co.,
against certain liabilities, including liabilities under the federal securities
laws, related to or arising out of its engagement. Wood, Warren & Co., as part
of its investment banking services, is regularly engaged in the valuation of
businesses and their securities in connection with mergers, acquisitions,
private placements and valuations for corporate reorganizations and other
purposes.

<PAGE>   205
1300. REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES; CORPORATE PURCHASE
AT FAIR MARKET VALUE; DEFINITIONS.

         (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.

         (b) As used in this chapter, "dissenting shares" means shares which
come within all of the following descriptions:

         (1) Which were not immediately prior to the reorganization or
short-form merger either (A) listed on any national securities exchange
certified by the Commissioner of Corporations under subdivision (o) of Section
25100 or (B) listed on the list of OTC margin stocks issued by the Board of
Governors of the Federal Reserve System, and the notice of meeting of
shareholders to act upon the reorganization summarizes this section and Sections
1301, 1302, 1303 and 1304; provided, however, that this provision does not apply
to any shares with respect to which there exists any restriction on transfer
imposed by the corporation or by any law or regulation; and provided, further,
that this provision does not apply to any class of shares described in * * *
subparagraph (A) or (B) if demands for payment are filed with respect to 5
percent or more of the outstanding shares of that class.

         (2) Which were outstanding on the date for the determination of
shareholders entitled to vote on the reorganization and (A) were not voted in
favor of the reorganization or, (B) if described in * * * subparagraph (A) or
(B) of paragraph (1) (without regard to the provisos in that paragraph), were
voted against the reorganization, or which were held of record on the effective
date of a short-form merger; provided, however, that * * * subparagraph (A)
rather than * * * subparagraph (B) of this paragraph applies in any case where
the approval required by Section 1201 is sought by written consent rather than
at a meeting.

         (3) Which the dissenting shareholder has demanded that the corporation
purchase at their fair market value, in accordance with Section 1301.

         (4) Which the dissenting shareholder has submitted for endorsement, in
accordance with Section 1302.

         (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

1301. NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS; DEMAND FOR
PURCHASE; TIME; contents.

         (a) If, in the case of a reorganization, any shareholders of a
corporation have a right under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation to
purchase their shares for cash, such corporation 

                                       1.
<PAGE>   206
shall mail to each such shareholder a notice of the approval of the
reorganization by its outstanding shares (Section 152) within 10 days after the
date of such approval, accompanied by a copy of Sections 1300, 1302, 1303, 1304
and this section, a statement of the price determined by the corporation to
represent the fair market value of the dissenting shares, and a brief
description of the procedure to be followed if the shareholder desires to
exercise the shareholder's right under such sections. The statement of price
constitutes an offer by the corporation to purchase at the price stated any
dissenting shares as defined in subdivision (b) of Section 1300, unless they
lose their status as dissenting shares under Section 1309.

         (b) Any shareholder who has a right to require the corporation to
purchase the shareholder's shares for cash under Section 1300, subject to
compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who
desires the corporation to purchase such shares shall make written demand upon
the corporation for the purchase of such shares and payment to the shareholder
in cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) or paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

         (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

1302. SUBMISSION OF SHARE CERTIFICATES FOR ENDORSEMENT; UNCERTIFICATED
SECURITIES.

         Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.

1303. PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR MARKET VALUE;
FILING; TIME OF PAYMENT.

         (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as 

                                       2.
<PAGE>   207
between the corporation and the holders thereof shall be filed with the
secretary of the corporation.

         (b) Subject to the provisions of Section 1306, payment of the fair
market value of dissenting shares shall be made within 30 days after the amount
thereof has been agreed or within 30 days after any statutory or contractual
conditions to the reorganization are satisfied, whichever is later, and in the
case of certificated securities, subject to surrender of the certificates
therefor, unless provided otherwise by agreement.

1304. ACTION TO DETERMINE WHETHER SHARES ARE DISSENTING SHARES OR FAIR MARKET
VALUE; LIMITATION; JOINDER; CONSOLIDATION; DETERMINATION OF ISSUES; APPOINTMENT
OF APPRAISERS.

         (a) If the corporation denies that the shares are dissenting shares, or
the corporation and the shareholder fail to agree upon the fair market value of
the shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

         (b) Two or more dissenting shareholders may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.

         (c) On the trial of the action, the court shall determine the issues.
If the status of the shares as dissenting shares is in issue, the court shall
first determine that issue. If the fair market value of the dissenting shares is
in issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

1305. REPORT OF APPRAISERS; CONFIRMATION; DETERMINATION BY COURT; JUDGMENT;
PAYMENT; APPEAL; COSTS.

         (a) If the court appoints an appraiser or appraisers, they shall
proceed forthwith to determine the fair market value per share. Within the time
fixed by the court, the appraisers, or a majority of them, shall make and file a
report in the office of the clerk of the court. Thereupon, on the motion of any
party, the report shall be submitted to the court and considered on such
evidence as the court considers relevant. If the court finds the report
reasonable, the court may confirm it.

         (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

         (c) Subject to the provisions of Section 1306, judgment shall be
rendered against the corporation for payment of an amount equal to the fair
market value of each dissenting share multiplied by the number of dissenting
shares which any dissenting shareholder who is a party, or who has intervened,
is entitled to require the corporation to purchase, with interest thereon at the
legal rate from the date on which judgment was entered.

                                       3.
<PAGE>   208
         (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

         (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301, and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

1306. PREVENTION OF IMMEDIATE PAYMENT; STATUS AS CREDITORS; INTEREST.

         To the extent that the provisions of Chapter 5 prevent the payment to
any holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

1307. DIVIDENDS ON DISSENTING SHARES.

         Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.

1308. RIGHTS OF DISSENTING SHAREHOLDERS PENDING VALUATION; WITHDRAWAL OF DEMAND
FOR PAYMENT.

         Except as expressly limited in this chapter, holders of dissenting
shares continue to have all the rights and privileges incident to their shares,
until the fair market value of their shares is agreed upon or determined. A
dissenting shareholder may not withdraw a demand for payment unless the
corporation consents thereto.

1309. TERMINATION OF DISSENTING SHARE AND SHAREHOLDER STATUS.

         Dissenting shares lose their status as dissenting shares and the
holders thereof cease to be dissenting shareholders and cease to be entitled to
require the corporation to purchase their shares upon the happening of any of
the following:

         (a) The corporation abandons the reorganization. Upon abandonment of
the reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorney's fees.

         (b) The shares are transferred prior to their submission for
endorsement in accordance with Section 1302 or are surrendered for conversion
into shares of another class in accordance with the articles.

         (c) The dissenting shareholder and the corporation do not agree upon
the status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six 

                                       4.
<PAGE>   209
months after the date on which notice of the approval by the outstanding shares
or notice pursuant to subdivision (i) of Section 1110 was mailed to the
shareholder.

         (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

1310. SUSPENSION OF RIGHT TO COMPENSATION OR VALUATION PROCEEDINGS; LITIGATION
OF SHAREHOLDERS' APPROVAL.

         If litigation is instituted to test the sufficiency or regularity of
the votes of the shareholders in authorizing a reorganization, any proceedings
under Sections 1304 and 1305 shall be suspended until final determination of
such litigation.

1311. EXEMPT SHARES.

         This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

1312. RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR RESCIND MERGER OR
REORGANIZATION; RESTRAINING ORDER OR INJUNCTION; CONDITIONS.

         (a) No shareholder of a corporation who has a right under this chapter
to demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

         (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days prior
notice to the corporation and upon a determination by the court that clearly no
other remedy will adequately protect the complaining shareholder or the class of
shareholders of which such shareholder is a member.

         (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is 

                                       5.
<PAGE>   210
just and reasonable as to the shareholders of the controlled party, and (2) a
person who controls two or more parties to a reorganization shall have the
burden of proving that the transaction is just and reasonable as to the
shareholders of any party so controlled.

               WHEREAS, it is the desire of the Board of Directors of this
         corporation pursuant to its authority as aforesaid, to fix the rights,
         preferences, restrictions and other matters relating to a first series

               NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors does
         hereby provide, pursuant to Article Fifth of the Articles of
         Incorporation, for the issuance of a first series of Preferred Stock of
         the Corporation, and it does hereby fix and determine the rights,
         preferences, restrictions and other matters relating to said series of

         I.    Title of Series

               The-first series of Preferred Stock shall be designated and known

         III.  Dividend Rights

                    The holders of the Preferred Stock, Series A shall be
               entitled to receive, out of funds legally available therefor,
               dividends at the rate of One Dollar Forty Cents ($1.40) per annum
               per share, payable in cash quarterly on the fifteenth (15th) day

               March 15, 1981, when and as declared by the Board of Directors of
               the Corporation. Such dividends shall not be cumulative;
               provided, however, that if the Corporation's independent
               certified public accountant determines, for any fiscal year, that
               the Corporation had after-tax earnings for such year, legally
               available for the payment of dividends, dividends will cumulate
               in an amount equal to the lesser of dividends payable but not
               declared during such fiscal year and after-tax earnings for such
               fiscal year. Dividends so cumulative will be paid or set apart
               for payment, but without interest, before the payment of any
               dividend on the common stock of the Corporation (the "Common
               Stock').

               Dividends shall be paid by forwarding a check, postage prepaid,
               to the address of each holder (or, in the 

                                      -2-
<PAGE>   218
case of joint holders, to the address of either such holder) of Preferred Stock,
Series A as shown on the books of the Corporation, unless such holder specifies
another address by written notice to the Corporation. The forwarding of such
check shall satisfy all obligations of the Corporation with respect to such
dividends, unless such check is not paid upor timely presentation.

               The holders of the Preferred Stock, Series A shall be entitled to
dividends as set forth in this Section III and no more. At any time after all
dividends on the Preferred Stock, Series A shall have been declared and paid or
set apart for payment in accordance with the provisions of this Section III,
dividends may be paid on outstanding Common Stock out of any funds legally
available therefor.

         IV. Liquidation Riqhts.

               In the event of any liquidation, dissolution and winding up of
the Corporation, whether voluntary or not, the holders of Preferred Stock,

Dollars ($20) plus all dividends to which they are entitled before any amount
shall be paid to holders of the Common Stock, and shall not be entitled to
receive any portion of the remaining assets of the Corporation.

         V. Voting Rights

               The holders of the Preferred Stock, Series A shall have one vote
for each full share of Common Stock into which their respective shares of
Preferred Stock, Series A, are convertible on all matters on which holders of
Common Stock are entitled to vote, and, except as expressly provided by law,

                                       -3-
<PAGE>   219
         (2) "Conversion Price" shall mean the price, determined pursuant to
         this Section VI, at which shares of Common Stock shall be deliverable
         upon conversion of Preferred Stock, Series A.

         (3) "Current Conversion Price" shall mean the Conversion Price
         immediately before the occurrence of any event, which, pursuant to
         Section VI.C, causes a redetermination of the Conversion Price.

         (4) "Convertible Securities" shall mean any indebtedness or shares of
         stock convertible into or exchangeable for Common Stock.

         (5) "Options" shall mean any rights or options to subscribe for or
         purchase Common Stock or Convertible Securities.

         (6) "Common Stock Outstanding" shall include all Common Stock issuable
         upon exercise of all outstanding Options and conversion of all
         outstanding Convertible Securities.

         (7) "Distribution" shall have the meaning of the term "distribution to
         its shareholders" in the California Corporations Code as in effect on
         the date of this certificate.

               B. Right to Convert; Initial Conversion Price. Each holder of the
         Preferred Stock, Series A may, at any time, upon surrender of the
         certificates therefor, convert any or all of his Preferred Stock,
         Series A into fully paid and non-assessable shares of Common Stock at
         the Conversion Price, each share of Preferred Stock, Series A being
         taken at Twenty Dollars ($20) for the purpose of such conversion. The
         Conversion Price shall initially be Twenty Dollars ($20) per share of
         Common Stock. Such initial Conversion Price shall be subject to
         adjustment from time to time in certain instances as hereinafter
         provided. No adjustments with respect to conversion shall be made on
         account of any dividends that may be cumulated but unpaid on the
         Preferred Stock, Series A surrendered for conversion, but no dividends
         shall thereafter be paid on the Common Stock unless such cumulated but
         unpaid dividends have first been paid to the holders at the time of
         conversion of the Preferred Stock, Series A.

               Before any holder of Preferred Stock, Series A shall be entitled
         to convert the same into Common Stock, he shall surrender the
         certificate or certificates therefor, duly

         such Preferred Stock, Series A, and shall give written notice to the
         Corporation at such office that he elects to convert the same. The
         Corporation shall, as soon as practicable thereafter, issue and deliver
         at such office to such holder of Preferred Stock, Series A, or to his
         nominee or nominees, certificates for the number of full shares of
         Common Stock to which he shall be entitled, together with cash in lieu
         of any fraction of a share as hereinafter provided, and, if ' less than
         all of the shares of Preferred Stock, Series A represented by such
         certificate are converted, a certificate representing the shares of
         Preferred Stock, Series A not converted. Such conversion shall be
         deemed to have been made as of the date of such surrender of the
         Preferred Stock, Series A to be converted, and the person or persons
         entitled to receive the Common Stock issuable upon such conversion
         shall be treated for all purposes as the record holder or holders of
         such Common Stock on such date.

         C. Adjustments to Conversion Price. Subject to Section VI.C.9, the
         Conversion Price in effect from time to time shall be subject to
         adjustment in certain cases as follows:

               1. Issuance of Securities. In case the Corporation shall at any
         time after the Series A Issuance Date (i) issue or sell any Common
         Stock without consideration, or for a consideration per share less than
         the Current Conversion price, or (ii) pay or make a dividend or other
         Distribution on the Common Stock (other than in cash out of its
         retained earnings, in Common Stock, in Convertible Securities, or in
         Options) then, and thereafter successively upon each such issuance,
         sale, dividend or other Distribution, the Current Conversion Price
         shall simultaneously with such issuance, sale, dividend or other
         Distribution be adjusted to a Conversion Price (calculated to the
         nearest cent) determined by dividing

                    (a) an amount equal to (i) the total number of shares of
               Common Stock Outstanding when the Current Conversion Price became
               effective multiplied by the Current Conversion Price, plus (ii)
               the aggregate of the amount of all consideration, if any,
               received by the Corporation for the issuance or sale of Common
               Stock since the Current Conversion Price became effective, minus
               (iii) the aggregate amount of all dividends or Distributions on
               Common Stock (other than in cash out of its retained earnings, in
               shares of Common Stock, in Convertible Securities, or in
               Options), paid by the Corporaton since the Current Conversion
               Price became effective, by

                                       -5-
<PAGE>   221
                    (b) the total number of shares of Common Stock Outstanding
               immediately after such issuance, sale, dividend, or other
               Distribution,

               except that the Current Conversion Price shall not be reduced if
               the amount of such reduction would be less than fifty cents
               ($.50), and in no event shall the Conversion Price exceed the
               Initial Conversion Price.

         For the purposes of this subsection VI.C.1, the following provisions
shall also be applicable:

               (i) Cash Consideration. In case of the issuance or sale of
         additional Common Stock for cash, the consideration received by the
         Corporation therefor shall be deemed to be the amount of cash received
         by the Corporation for such shares (or, if such shares are offered by
         the Corporation for subscription, the subscription price, or, if such
         shares are sold to underwriters or dealers for public offering without
         a subscription offering, the initial public offering price), without
         deducting there from any compensation or discount paid or allowed to
         underwriters or dealers or others performing similar services or for
         any expenes incurred in connection therewith.

               (ii) Non-Cash Consideration. In case of the issuance (Otherwise
         than upon conversion or exchange of Convertible Securities) or sale of
         additional Common Stock, Options or Convertible Securities for a
         consideration other than cash or a consideration a part of which shall
         be other than cash, the fair value of such consideration as determined
         by the Board of Directors of the Corporation in the good faith exercise
         of its business judgment, irrespective of the accounting treatment
         thereof, shall be deemed to be the value, for purposes of this Section
         VI, of the consideration other than cash received by the Corporation
         for such securities.

               (iii) Options and Convertible Securities. In case the Corporation
         shall in any manner issue or grant any Options or any Convertible
         Securities, the total maximum number of shares

                                       -6-
<PAGE>   222
         of Common Stock issuable upon the exercise of such Options or upon
         conversion or exchange of the total maximum amount of such Convertible
         Securities at the time such Convertible Securities first become
         convertible or exchangeable shall (as of the date of issue or grant of
         such Options or, in the case of the issue or sale of Convertible
         Securities other than where the same are issuable upon the exercise of
         Options, as of the date of such issue or sale) be deemed to be issued
         and to be outstanding for the purpose of this subsection VI.C.1 and to
         have been issued for the price per share for which shares of Common
         Stock are issuable upon the exercise of such Options or upon conversion
         or exchange of such Convertible Securities at the time such Convertible
         Securities first become convertible or exchangeable; provided that,
         subject to the provisions of subsection VI.C.2, no further adjustment
         of the Conversion Price shall be made upon the actual issuance of any
         such Common Stock or Convertible Securities or upon the conversion or
         exchange of any such Convertible Securities.
   

               (iv) Dividends in Common Stock, Options, or Convertible
         Securities. In the case of the issuance of additional Common Stock,
         Options, or Convertible Securities as a dividend or as a Distribution
         on Common Stock, the aggregate number of shares of Common Stock issued
         (or deemed issued pursuant to Section VI.C.1(iii)) in payment of such
         dividend or Distribution shall be deemed to have been issued on the
         record date for such dividend or Distribution and shall be deemed to
         have been issued without consideration.
    

               (v) Other Dividends. In case of the payment or making of a
         dividend or other Distribution on Common Stock in property (excluding
         Common Stock, Convertible Securities and Options, but including all
         other securities), such dividend or other Distribution shall be deemed
         to have been paid or made on the record date for such dividend or other
         Distribution and in the amount of such dividend or other Distribution
         in property on such record date, as determined by the Board of
         Directors of the Corporation.

                                       -7-
<PAGE>   223
               (vi) Reclassification. The reclassification of securities other
         than Common Stock into securities including Common Stock shall be
         deemed to involve the issuance for a consideration other than cash of
         such Common Stock at the close of business on the date fixed for the
         determination of shareholders entitled to receive such Common Stock.

               (vii) Record Date. In the event that there shall be no record
         date for the determination of shareholders entitled to any dividend or
         Distribution declared by the Corporation, the first business day during
         which the stock transfer books of the Corporation shall be closed for
         the purpose of such determination shall be deemed to be the record date
         for the determination of shareholders entitled to such dividend or
         Distribution.

         2. Change in Option Price or Conversion Rate. In the event that the
         purchase price provided for in any Option referred to in subsection
         VI.C.1(iii), or the rate at which any Convertible Securities referred
         to in subsection VI.C.1(iii) are convertible into or exchangeable for
         shares of Common Stock shall change at any time (other than under or by
         reason of provisions designed to protect against dilution), the Current
         Conversion Price in effect at the time of such event shall forthwith be
         readjusted to the Conversion Price that would have been in effect at
         such time had such Options or Convertible Securities still outstanding
         provided for such changed purchase price, additional consideration or
         conversion rate, as the case may be, at the time initially granted,
         issued or sold. In the event that the purchase price provided for in
         any such Option referred to in subsection VI.C.1(iii), or the
         additional consideration (if any) payable upon the conversion or
         exchange of any Convertible Securities referred to in subsection
         VI.C.1(iii), or the rate at which any Convertible Securities referred
         to in subsection VI.C.1(iii) are convertible into or exchangeable for
         shares of Common Stock, shall be reduced at any time under or by reason
         of provisions with respect thereto designed to protect against
         dilution, then in case of the delivery of shares of Common Stock upon
         the exercise of any such Option or upon conversion or exchange of any
         such Convertible Security, the Current Conversion Price then in effect
         hereunder shall, upon issuance of such shares of Common Stock, be
         adjusted to such amount as would have

                                       -8-
<PAGE>   224
         obtained had such Option or Convertible Security never been issued and
         had adjustments been made only upon the issuance of the shares of
         Common Stock delivered as aforesaid.

               3. Termination of Option or Conversion Rights. In the event of
         the termination or expiration of any right to purchase Common Stock
         under any Option or of any right to convert or exchange Convertible
         Securities, the Current Conversion Price shall, upon such termination,
         be changed to the Conversion Price that would have been in effect at
         the time of such expiration or termination had such Option or
         Convertible Security, to the extent outstanding immediately prior to
         such expiration or termination, never been issued, and the shares of
         Common Stock issuable thereunder shall no longer be deemed to be Common
         Stock Outstanding.

               4. Stock Splits. In the event the out standing Common Stock shall
         be subdivided into a greater number of shares of Common Stock, the
         Current Conversion Price shall, simultaneously with the effectiveness
         of such subdivision, be proportionately reduced, and conversely,in case
         the outstanding Common Stock shall be combined into a smaller number of
         shares of Common Stock, the Current Conversion Price shall,
         simultaneously with the effectiveness of such combination, be
         proportionately increased. For the purposes of subsections VI.C.1 and
         VI.C.4, a distribution of Common Stock to holders of Common Stock in
         which the number of shares distributed is 25 percent (25%) or more of
         the number of shares of Common Stock upon which the distribution is to
         be made shall be deemed to be a subdivision of Common Stock, and a
         distribution of a lesser number of shares of Common Stock shall be
         deemed to be a stock dividend.

               5. Successive Changes. The above provisions of this Section VI
         shall similarly apply to successive issuances, sales, dividends or
         other Distributions,subdivisions and combinations on or of the Common
         Stock after the Series A Issuance Date.

               6. Merger; Sale of Corporation. Subject to Section IV, in the
         event, after the Series A Issuance Date, of any consolidation of the
         Corporation with, or merger of the Corporation with or into another
         corporation (other than a consolidation or merger in which the
         Corporation is the continuing corporation and which does

                                       -9-
<PAGE>   225
         not result in any reclassification of, or change in, the outstanding
         shares of Common Stock), or in case of any sale or transfer to another
         corporation of all or substantially all of the assets of the
         Corporation, each share of Preferred Stock, Series A shall be treated
         for all purposes as if it had been converted into Common Stock on the
         earlier of (i) the record date, if any, for voting by holders of Common
         Stock on such event and (ii) the date of such event.

               7. Other Events Altering Conversion Price. Upon the occurrence of
         any event not specifically denominated in this Section VI as altering
         the Conversion Price that, in the reasonable exercise of the business
         judgment of the Board of Directors of the Corporation requires, on
         equitable principles, the alteration of the Conversion Price, the
         Conversion Price will be equitably altered.

               8. Miscellaneous Conversion Price Matters. The Corporation shall
         at all times reserve and keep available out of its authorized but
         unissued Common Stock the full number of shares of Common Stock
         deliverable upon conversion of all the then outstanding Preferred
         Stock, Series A, and shall, at its own expense, take all such actions
         and obtain all such permits and orders as may be necessary to enable
         the Corporation lawfully to issue such Common Stock upon the conversion
         of such Preferred Stock. No fractions of Common Stock shall be issued
         upon the conversion of Preferred Stock, Series A, and in lieu thereof
         the Corporation shall pay the holder an amount in cash equal to the
         fair market value of such fractional interest as determined by the
         Board of Directors of the Corporation in the exercise of its good faith
         business judgment.

               9. Excluded Events. Notwithstanding anything in this Section VI
         to the contrary, the Conversion Price shall not be adjusted by virtue
         of the issuance or sale of an aggregate of not more than 20,000 shares
         of Common Stock to employees of the Corporation at a price,which is
         less than the Conversion Price at the time of such issuance or sale
         (all as determined in accordance with this Section VI).

               D. Mandatory Conversion. At any time on or after the earlier of
         (a) the date on which any Common Stock is sold to the public by the
         Corporation (or selling shareholders, if any) in a public offering
         registered under the Securities Act of 1933 at a per share public
         offering price of not less 

                                      -10-
<PAGE>   226
         than twice the Conversion Price (as defined in Section VI.A(2) hereof)
         then in effect, or (b) the expiration of three (3) years after the
         Series A Issuance Date (as defined in Section VI.A.(3), then, in either
         case, the Corporation, may, at its election, cause all or any portion
         of the Preferred Stock, Series A to be converted at the Conversion
         Price then in effect.

         The Corporation shall give notice of its election to cause conversion
         under this Section VI.D by mail, postage prepaid, at least 15 days
         prior to the date specified for conversion, to each holder of record of
         the Preferred Stock, Series A at the address of such holder as the same
         shall appear on the books of the Corporation, which notice shall
         specify said conversion date, the Conversion Price, the number of
         shares of Common Stock to be issued upon such conversion, the amount of
         the cash adjustment to be paid in respect of a fractional share of
         Common Stock and the amount of any dividends cumulated Sand unpaid
         prior to such conversion date. On and after said conversion date,
         notwithstanding that any certificates for the Preferred Stock, Series A
         shall not have been surrendered for conversion, the shares of Preferred
         Stock, Series A evidenced thereby shall be deemed to be no longer
         outstanding, and all rights with respect thereto shall forthwith cease
         and terminate, except only the rights of the holder (i) to receive the
         shares of Common Stock to which he shall be entitled upon conversion
         thereof, (ii) to receive the amount of cash payable in respect of any
         fractional share of Common Stock to which he shall be entitled, and
         (iii) with respect to dividends cumulated but unpaid on such Preferred
         Stock, Series A prior to such conversion date.

         VII.  Warrant.

               Subject to the terms and conditions hereinafter set forth, each
         holder of Preferred Stock, Series A, is hereby granted the right (a
         "Warrant"), to purchase, upon (but only upon and in no event after)
         conversion into Common Stock of the shares of Preferred Stock, Series A
         to which such Warrant relates, one share of Common Stock for each five
         share of Preferred Stock, Series A, held, at a price ("Exercise Price")
         of Twenty Dollars ($20.00) per share of Common Stock.

               The Warrants are exercisable at the office of the Corporation, or
         such other office or agency as the Corporation may from time to time
         designate, upon surrender of the certificate for the holder's Preferred
         Stock, Series A for conversion into shares of Common Stock and payment
         of the Exercise Price for the shares of Common Stock to be purchased

                                      -11-
<PAGE>   227
         on such exercise, in United States currency, either in cash, or by
         certified or official bank check payable to the order of the
         Corporation.

               A Warrant may be exercised only in full, only upon conversion of
         all Preferred Stock, Series A held by the holder making such exercise,
         and only upon exercise of all Warrants relating to such holder's shares
         of Preferred Stock, Series A.

               Shares of Common Stock sufficient to provide for the exercise of
         the Warrants shall at all times be reserved by the Corporation for
         issuance upon exercise. All shares of Common Stock issuable upon the
         exercise of the Warrants shall be validly issued, full paid and
         non-assessable.

               VIII. Certain Taxes

               The Corporation shall pay any and all issuance and other taxes
         (excluding any federal or state income taxes) that may be payable in
         respect of any issuance or delivery of shares of Common Stock on
         conversion of Preferred Stock, Series A, or on exercise of any Warrant.
         The Corporation shall not, however, be required to pay any tax that may
         be payable in respect of any transfer involved in the issuance and
         delivery of shares of Common Stock in a name other than that in which
         the shares of Preferred Stock, Series A to which such issuance relates
         were registered, and no such issuance or delivery shall be made unless
         and until the person requesting such issuance has paid to the
         Corporation the amount of any such tax, or it is established to the
         satisfaction of the Corporation that such tax has been paid.

               RESOLVED FURTHER, that the President or any Vice President and
         the Secretary or any Assistant Secretary of this Corporation be, and
         they hereby are, authorized and directed to prepare and file a

appointment at the meeting. The number of inspectors shall be either one or
three. If appointed at a meeting on the request of one or more shareholders or
proxies, the majority of shares represented in person or by proxy shall
determine whether one or three inspectors are to be nominated. In case any
person

                                                                            II-5
<PAGE>   240

may, and on the request of any shareholder or a shareholder's proxy shall, be
filled by appointment by the board of directors in advance of the meeting, or at
the meeting by the chairman of the meeting.

         The duties of such inspectors shall be as prescribed by Section 707 of
the General Corporation Law and shall include: determining the number of shares
outstanding and the voting power of each, the shares represented at the meeting,
the existence of a quorum, the authenticity, validity and effect of proxies;
receiving votes, ballots or consents; hearing and determining all challenges and
questions in any way arising in connection with the right to vote; counting and
tabulating all votes or consents; determining when the polls shall close;
determining the result; and such acts as may be proper to conduct the election
or vote with fairness to all shareholders. In the determination of the validity
and effect of proxies the dates contained on the forms of proxy shall
presumptively determine the order of execution of the proxies, regardless of the
postmark dates on the envelopes in which they are mailed.

         The inspectors of election shall perform their duties impartially, in
good faith, to the best of their ability and as expeditiously as is practical.
If there are three inspectors of election, the decision, act or certificate of a
majority is effective in all respects as the decision, act or certificate of
all. Any report or certificate made by the inspectors of election is prima facie
evidence of the facts stated therein.

                                                                            II-6

domestic corporation, partnership, joint venture, trust or other enterprise;

         (i) The corporation shall have power to indemnify any person who was or
is a party or is threatened to be made a party to any proceeding (other than an
action by or in the right of the corporation to procure a judgment in its favor)
by reason of the fact that such person is or was an agent of the corporation,
against expenses, judgments, fines, settlements and other amounts actually and
reasonably incurred in connection with such proceeding if such person acted in
good faith and in a manner such person reasonably believed to be in the best
interests of the corporation and, in the case of a criminal proceeding, had no
reasonable cause to believe the conduct of such person was unlawful. The
termination of any proceeding by judgment, order, settlement

                                                                             V-3

<PAGE>   253
conviction or upon a plea of nolo contendere or its equivalent shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which the person reasonably believed to be in the best interests of the
corporation or that the person had reasonable cause to believe that the person's
conduct was unlawful.

(ii) A corporation shall have power to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action by or in the right of the corporation to procure a judgment in
its favor by reason of the fact that such person is or was an agent of the
corporation, against expenses actually and reasonably incurred by such person in
connection with the defense or settlement of such action if such person acted in
good faith, in a manner such person believed to be in the best interests of the
corporation and with such care, including reasonable inquiry, as an ordinarily
prudent person in a like position would use under similar circumstances. No
indemnification shall be made under this subdivision (b):

         (A) In respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the corporation in the performance of
such person's duty to the corporation, unless and only to the extent that the
court in which such proceeding is or was pending shall determine upon
application that, in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for the expenses which such court
shall determine;

         (B) Of amounts paid in settling or otherwise disposing of a threatened
or pending action, with or without court approval; or

         (C) Of expenses incurred in defending a threatened or pending action
which is settled or otherwise disposed of without court approval.

         (c) Expenses. To the extent that an agent of a corporation has been
successful on the merits in defense of any proceeding referred to in subdivision
(b) or in defense of any claim, issue or matter therein, the agent shall be
indemnified against expenses actually and reasonably incurred by the agent in
connection therewith.

                                                                             V-4
<PAGE>   254
(d) Vote Authorizing Indemnification. Except as provided in subdivision (c), any
indemnification under this section shall be made by the corporation only if
authorized in the specific case, upon a determination that indemnification of
the agent is proper in the circumstances because the agent has met the
applicable standard of conduct set forth in subdivision (b) or (c), by:

(i) A majority vote of a quorum consisting of directors who are not parties to
such proceeding;

(ii) Approval of the shareholders by majority vote, with the shares owned by the
person to be indemnified not being entitled to vote thereon; or

(iii) The court in which such proceeding is or was pending upon application made
by the corporation or the agent or the attorney or other person rendering
services in connection with the defense, whether or not such application by the
agent, attorney or other person is opposed by the corporation.

(e) Advancement of Expenses. Expenses incurred in defending any proceeding may
be advanced by the corporation prior to the final disposition of such proceeding
upon receipt of an undertaking by or on behalf of the agent to repay such amount
unless it shall be determined ultimately that the agent is entitled to be
indemnified as authorized in this section.

(f) Validity and Limitation. No provision made by a corporation to indemnify its
or its subsidiary's directors or officers for the defense of any proceeding,
whether contained in the articles, bylaws, a resolution of shareholders or
directors, an agreement or otherwise, shall be valid unless consistent with this
section. Nothing contained in this section shall affect any right to
indemnification to which persons other than such directors and officers may be
entitled by contract or otherwise.

(g) No indemnification or advance shall be made under this section, except as
provided in subdivision (c) or paragraph (iii) of subdivision (d), in any
circumstance where it appears:

                                                                             V-5
<PAGE>   255
(i) That it would be inconsistent with a provision of the articles, bylaws, a
resolution of the shareholders or an agreement in effect at the time of accrual
of the alleged cause of action asserted in the proceeding in which the expenses
were incurred or other amounts were paid, which prohibits or otherwise limits
indemnification; or

(ii) That it would be inconsistent witn any condition expressly imposed by a
court in approving a settlement.

(h) Purchase o,f Insurance. The corporation shall have power to purchase and
maintain insurance on behalf of any agent of the corporation against any
liability asserted against or incurred by the agent in such capacity or arising
out of the agent's status as such whether or not the corporation would have the
power to indemnify the agent against such liability under the provisions of this
section.

(i) Trustee, Etc. Excluded. This section does not apply to any proceeding
against any trustee, investment manager or other fiduciary of an employee
benefit plan in such person's capacity as such, even though such person may also
be an agent as defined in subdivision (a) of the employer corporation. A
corporation shall have power to indemnify such a trustee, investment manager or
other fiduciary to the extent permitted by General Corporation Law subdivision
(f) of Section 207.

Section 7. Record Date. In order that the corporation may determine the
shareholders entitled to notice of any meeting or to vote or entitled to receive
payment of any dividend or other distribution or allotment of any rights or
entitled to exercise any rights in respect of any other lawful action, the board
may fix, in advance, a record date, which shall not be more than 60 nor less
than 10 days prior to the date of such meeting nor more than 60 days prior to
any other action.

Section 8. Construction and Definitions. Unless the context otherwise requires,
the general provisions, rules of constructions and definitions contained in the
California General Corporation Law shall govern the construction of these
bylaws.

                                                                             V-6

         Section 1. Power of Shareholders. New bylaws may , be adopted or these
bylaws may be amended or repealed by the affirmative vote of a majority of the
outstanding shares entitled to vote, or by the written assent of shareholders
entitled to vote such shares except as otherwise provided by law or by the
articles of incorporation.

Section 2. Power of Directors. Subject to the right of shareholders as provided
in Section l of this Article VI to adopt, amend or repeal bylaws, bylaws may be
adopted, amended or repealed by the board of directors provided, however, that
the board of directors may adopt a bylaw or amendment thereof changing the
authorized number of directors only for the purpose of fixing the exact number

bylaws.

                                                                            VI-1

enter into a Registration  Rights Agreement (in the form of Exhibit 10.01 to the
Reorganization  Agreement) with the former  shareholders  of ASCOR.  Pursuant to
Section  2.14 of the  Registration  Rights  Agreement  the  registration  rights
granted thereunder will not be available if the Giga-tronics Common Stock issued
in  the  merger  was  "issued  by  Giga-tronics  to  the  Holder  pursuant  to a
registration statement filed with the SEC".

                  Giga-tronics  believes it is in the interests of  Giga-tronics
and the combined  companies to issue the  Giga-tronics  Common Stock pursuant to
such a registration  statement.  Therefore,  Giga-tronics  now agrees to use its
best faith  efforts to file with the  Securities  and Exchange  Commission,  and
cause  the  effectiveness  under  federal  securities  law  of,  a  registration
statement  on Form S-4 (or such other form as may be  applicable)  covering  the
shares of Giga-tronics Common Stock to be issued in the Merger.

                  The  undersigned  hereby  agree that upon the issuance of such
Giga-tronics  Common Stock pursuant to an effective  registration  statement the
Registration  Rights Agreement will be of no force and effect and will therefore
not be delivered at the Closing.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Giga-tronics is incorporated in California. Under Section 317 of the
California Corporation Code (the "CCC"), a California corporation generally has
the power to indemnify its present and former directors and officers against
expenses, judgments, fines, settlements and other amounts actually paid and
reasonably incurred by them in connection with any threatened, pending or
completed action or proceeding so long as they acted in good faith and in a
manner they reasonably believed to be in the best interests of the company, and
with respect to any criminal action, they had no reasonable cause to believe
their conduct was unlawful.

         The Articles of Incorporation of Giga-tronics (the "Articles") and the
Bylaws of Giga-tronics (the "Bylaws") provide that Giga-tronics has the powers
of indemnification as specified in Section 317 of the CCC. The Bylaws provide to
the extent an agent of Giga-tronics has been successful on the merits in defense
of a proceeding relating to which Giga-tronics has the power to indemnify them,
the agent shall be indemnified against expenses actually and reasonably incurred
by the agent in connection therewith. The Bylaws further provide that except in
such cases where an agent is successful on the merits in such defense,
indemnification is to be made only upon a determination that indemnification is
proper in the circumstances because the agent met standards of conduct as
determined by (i) a majority vote of a quorum consisting of directors who are
not parties to such proceeding; (ii) approval of the shareholders by majority
vote, with the shares owned by the person to be indemnified not being entitled
to vote thereon; or (iii) the court in which such proceeding is or was pending
upon application made by the corporation or the agent or the attorney or other
person rendering services in connection with the defense, whether or not such
application by the agent, attorney or other person is opposed by the
corporation.

         Section 204(a)(10) of the CCC provides that Articles of Incorporation
may, subject to certain provisos, contain a provision eliminating or limiting
the personal liability of a director for monetary damages in an action brought
by or in the right of the company for breach of a director's duty to the company
and its shareholders. The Articles provide that the liability of the directors
of Giga-tronics for monetary damages will be eliminated to the fullest extent
permissible under California law.

ITEM 22.  UNDERTAKINGS

         (a)  The undersigned registrants hereby undertake:

                  (1) To file, during any period in which offers or sales are
         being made, a post-effective amendment to this registration statement:

                           (i)  To include any prospectus required by Section 
                  10(a)(3) of the Securities Act of 1993;

                           (ii) To reflect in the prospectus any facts or events
                  arising after the effective date of the registration statement
                  (or the most recent post-effective amendment thereof) which,
                  individually or in the aggregate, represent a fundamental
                  change in the information set forth in the registration
                  statement. Notwithstanding the foregoing, any increase or
                  decrease in volume of securities offered (if the total dollar
                  value of securities offered would not exceed that which was
                  registered) and any deviation from the low or high and of the
                  estimated maximum offering range may be reflected in the form
                  of prospectus filed with the Commission pursuant to Rule
                  424(b) if, in the aggregate, the changes in volume and price
                  represent no more than 20 percent change in the maximum
                  aggregate offering price set forth in the "Calculation of
                  Registration Fee" table in the effective registration
                  statement;

                           (iii) To include any material information with
                  respect to the plan of distribution not previously disclosed
                  in the registration statement or any material change to such
                  information in the registration statement.

                  (2) That, for the purpose of determining any liability under
         the Securities Act of 1933, each such post-effective amendment shall be
         deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time shall
         be deemed to be the initial bona fide offering thereof.

                  (3) To remove from registration by means of a post-effective
         amendment any of the securities being registered which remain unsold at
         the termination of the offering.

         (b)      (1) The undersigned Registrant hereby undertakes as follows: 
         that prior to any public reoffering of the securities registered
         hereunder through use of a prospectus which is a part of this
         Registration Statement, by any person or party who is deemed to be an
         underwriter within the meaning of Rule 145(c), the issuer undertakes
         that such reoffering prospectus will contain the information called for
         by the applicable registration form with respect to reofferings by 
         persons who may be deemed underwriters, in addition to the information
         called for by the other items of the applicable form.

                  (2) The Registrant undertakes that every prospectus (i) that
         is filed pursuant to the immediately preceding paragraph b.(1), or (ii)
         that purports to meet the requirements of Section 10(a)(3) of the Act
         and is used in connection with an offering of securities subject to
         Rule 415, will be filed as a part of an amendment to the Registration
         Statement and will not be used until such amendment is effective, and
         that, for purposes of determining any liability under the Securities
         Act, each such post-effective amendment shall be deemed to be a new
         registration statement relating to the
<PAGE>   267
         securities offered therein, and the offering of such securities at that
         time shall be deemed to be the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
         Securities Act may be permitted to directors, officers and controlling
         persons of the Registrant pursuant to the foregoing provisions, or
         otherwise, the Registrant has been advised that in the opinion of the
         Securities and Exchange Commission such indemnification is against
         public policy as expressed in the Securities Act and is, therefore,
         unenforceable. In the event that a claim for indemnification against
         such liabilities (other than the payment by the Registrant of expenses
         incurred or paid by a director, officer or controlling person of the
         Registrant in the successful defense of any action, suit or proceeding)
         is asserted by such director, officer or controlling person in
         connection with the securities being registered, the Registrant will,
         unless in the opinion of its counsel the matter has been settled by
         controlling precedent, submit to a court of appropriate jurisdiction
         the question whether such indemnification by it is against public
         policy as expressed in the Securities Act and will be governed by the
         final adjudication of such issue.

         (d) The undersigned Registrant hereby undertakes to supply by means of
         a post-effective amendment all information concerning a transaction,
         and the company being acquired involved therein, that was not the
         subject of and included in the Registration Statement when it became
         effective.

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant has duly caused this Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of San Ramon,

Giga-tronics Incorporated
4650 Norris Canyon Road
San Ramon, California 94583

ASCOR, Inc.
47790 Westinghouse Drive
Fremont, California 94539

Ladies and Gentlemen:

                This opinion is being delivered to you pursuant to Section
8.03(b) of the Agreement and Plan of Reorganization (the "Agreement") among
Giga-tronics Incorporated, a California corporation ("Giga-tronics"), its wholly
owned subsidiary, ASCOR Acquisition Corp., a California corporation ("Sub"), and
ASCOR, Inc., a California corporation ("ASCOR"), dated May 2, 1996. Pursuant to
the Agreement, Sub will merge with and into ASCOR (the "Merger"), and ASCOR will
become a wholly owned subsidiary of Giga-tronics.

                Except as otherwise provided, capitalized terms referred to
herein have the meanings set forth in the Agreement. All section references,
unless otherwise indicated, are to the Internal Revenue Code of 1986, as amended
(the "Code").

                We have acted as legal counsel to Giga-tronics and Sub in
connection with the Merger. As such, and for the purpose of rendering this
opinion, we have examined (or will examine on or prior to the Effective Date)
and are relying (or will rely) upon (without any independent investigation or
review thereof) the truth and accuracy, at all relevant times, of the
statements, covenants, representations and warranties contained in the following
documents (including all schedules and exhibits thereto):

                1.      The Agreement;

                2.      Representations made to us by Giga-tronics and Sub in a 
letter reproduced as an exhibit hereto;

                                                                          Page 2





                  3. Representations made to us by ASCOR in a letter reproduced
as an exhibit hereto;

                  4. Representations made by certain shareholders of ASCOR in
"Affiliates Agreements";

                  5. The Registration Statement filed with respect to the
Merger; and

                  6. Such other instruments and documents related to the
formation, organization and operation of Giga-tronics, ASCOR and Sub or to the
consummation of the Merger and the transactions contemplated thereby as we have
deemed necessary or appropriate.

                  In connection with rendering this opinion, we have assumed or
obtained representations (and are relying thereon, without any independent
investigation or review thereof) that:

                  1. Original documents (including signatures) are authentic,
documents submitted to us as copies conform to the original documents, and there
has been (or will be by the Effective Time) due execution and delivery of all
documents where due execution and delivery are prerequisites to effectiveness
thereof;

                  2. The Merger will be consummated in accordance with the
Agreement and will be effective under the laws of the State of California;

                  3. The shareholders of ASCOR do not, and will not on or before
the Effective Date, have an existing plan or intent to dispose of an amount of
Giga-tronics Common Stock to be received in the Merger (or to dispose of ASCOR
capital stock in anticipation of the Merger) such that the shareholders of ASCOR
will not receive and retain a meaningful continuing equity ownership in
Giga-tronics that is sufficient to satisfy the continuity of interest
requirement as specified in Treasury Regulations Section 1.368-1(b) and as
interpreted in certain Internal Revenue Service rulings and federal judicial
decisions;

                  4. After the Merger, ASCOR will hold "substantially all" of
its and Sub's properties within the meaning of Section 368(a)(2)(E)(i) of the
Code and the regulations promulgated thereunder;

                  5. To the extent any expenses relating to the Merger (or the
"plan of reorganization" within the meaning of Treasury Regulations Section
1.368-1(c) with respect to the Merger) are funded directly or indirectly by a
party other than the


<PAGE>   3

incurring party, such expenses will be within the guidelines established in
Revenue Ruling 73-54, 1973-1 C.B. 187; and

                6. At all relevant times, including as of the Effective Time,
(i) no outstanding indebtedness of ASCOR, Giga-tronics or Sub has or will
represent equity for tax purposes; and (ii) no outstanding equity of ASCOR,
Giga-tronics or Sub has or will represent indebtedness for tax purposes.

                Based on our examination of the foregoing items and subject to
the assumptions, exceptions, limitations and qualifications set forth herein, we
are of the opinion that, for federal income tax purposes, the Merger will be a
"reorganization" as defined in Section 368(a) of the Code.

                In addition to the assumptions set forth above, this opinion is
subject to the exceptions, limitations and qualifications set forth below.

                1. This opinion represents and is based upon our best judgment
regarding the application of federal income tax laws arising under the Code,
existing judicial decisions, administrative regulations and published rulings
and procedures. Our opinion is not binding upon the Internal Revenue Service or
the courts, and there is no assurance that the Internal Revenue Service will not
successfully assert a contrary position. Furthermore, no assurance can be given
that future legislative, judicial or administrative changes, on either a
prospective or retroactive basis, would not adversely affect the accuracy of the
conclusions stated herein. Nevertheless, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
federal income tax laws.

                2. This opinion addresses only the classification of the Merger
as a reorganization under Section 368(a) of the Code, and does not address any
other federal, state, local or foreign tax consequences that may result from the
Merger or any other transaction (including any transaction undertaken in
connection with the Merger). In particular, we express no opinion regarding (i)
whether and the extent to which any ASCOR shareholder who has provided or will
provide services to ASCOR, Giga-tronics or Sub will have compensation income
under any provision of the Code; (ii) the effects of such compensation income,
including but not limited to the effect upon the basis and holding period of the
Giga-tronics stock received by any such shareholder in the Merger; (iii) the
potential application of the "golden parachute" provisions (Sections 280G,
3121(v)(2) and 4999) of the Code, the alternative minimum tax provisions
(Sections 55, 56 and 57) of the Code or Sections 305, 306, 357, 424, and 708, or
the regulations promulgated thereunder; (iv) other than that the Merger will be
a reorganization within the meaning of Code Section 368 and the consequences
that follow directly and solely

from such characterization, the corporate level tax consequences of the Merger
to Giga-tronics, Sub or ASCOR, including without limitation the survival and/or
availability, after the Merger, of any of the federal income tax attributes or
elections of ASCOR, after application of any provision of the Code, as well as
the regulations promulgated thereunder and judicial interpretations thereof; (v)
the basis of any equity interest in ASCOR acquired by Giga-tronics in the
Merger; (vi) the tax consequences of any transaction in which ASCOR stock or a
right to acquire ASCOR stock was received; (vii) the tax consequences of the
Merger to holders of options or warrants for ASCOR stock; or (viii) the tax
consequences that may be relevant to particular classes of ASCOR stockholders
such as dealers in securities, corporate shareholders subject to the alternative
minimum tax, foreign persons, and holders of shares acquired upon exercise of
stock options or in other compensatory transactions.

                3. No opinion is expressed as to any transaction other than the
Merger as described in the Agreement or to any transaction whatsoever, including
the Merger, if all the transactions described in the Agreement are not
consummated in accordance with the terms of such Agreement and without waiver or
breach of any material provision thereof or if all of the representations,
warranties, statements and assumptions upon which we relied are not true and
accurate at all relevant times. In the event any one of the statements,
representations, warranties or assumptions upon which we have relied to issue
this opinion is incorrect, our opinion might be adversely affected and may not
be relied upon.

                4. This opinion has been delivered to you for the purpose of
satisfying the conditions set forth in Section 8.03(b) of the Agreement and is
intended solely for your benefit; it may not be relied upon for any other
purpose or by any other person or entity, and may not be made available to any
other person or entity without our prior written consent. We hereby consent to
the filing of this opinion as an exhibit to the Registration Statement and
further consent to all references to us in the Registration Statement.

                                          Very truly yours,

                      corporation ("Sub")

Ladies and Gentlemen:

               This letter is supplied to you in connection with your rendering
of an opinion pursuant to Section 8.03(b) of the Agreement regarding certain
federal income tax consequences of the Merger. Unless otherwise indicated,
capitalized terms not defined herein have the meanings set forth in the
Agreement.


A.      REPRESENTATIONS

               On behalf of Giga-tronics and Sub, the undersigned hereby certify
and represent that the following facts are now true and will continue to be true
as of the Effective Date of the Merger:

               1. Pursuant to the Merger, Sub will merge with and into ASCOR,
and ASCOR will acquire all of the assets and liabilities of Sub. At least ninety
percent (90%) of the fair market value of the net assets and at least seventy
percent (70%) of the fair market value of the gross assets held by ASCOR
immediately prior to the Merger will continue to be held by ASCOR immediately
after the Merger. For the purpose of determining the percentage of ASCOR's net
and gross assets held by it immediately following the Merger, the following
assets will be treated as property held by ASCOR immediately prior but not
subsequent to the Merger: (i) assets disposed of by ASCOR prior to or subsequent
to the Merger and in contemplation thereof (including without limitation any
asset disposed of by ASCOR, other than in the ordinary course of

                                                                          Page 2




business, pursuant to a plan or intent existing during the period ending on the
Effective Date and beginning with the commencement of negotiations (whether
formal or informal) with Giga-tronics regarding the Merger (the "Pre-Merger
Period")), (ii) assets used by ASCOR to pay expenses or liabilities incurred in
connection with the Merger, and (iii) assets used to make distribution,
redemption or other payments in respect of ASCOR capital stock or rights to
acquire such stock (including payments to dissenters) that are made in
contemplation of the Merger or related thereto;

               2. Giga-tronics is participating in the Merger for good and valid
business reasons and not for tax purposes;

               3. Prior to the Merger, Giga-tronics will be in "Control" of Sub.
As used herein, "Control" of a corporation shall consist of ownership of stock
possessing at least eighty percent (80%) of the total combined voting power of
all classes of stock entitled to vote and at least eighty percent (80%) of the
total number of shares of all other classes of stock of the corporation. For
purposes of determining Control, a person shall not be considered to own voting
stock if rights to vote such stock (or to restrict or otherwise control the
voting of such stock) are held by a third party (including a voting trust) other
than an agent of such person;

               4. In the Merger, all shares of ASCOR capital stock will be
exchanged solely for voting stock of Giga-tronics, except to the extent of cash
paid to dissenters and cash paid in lieu of fractional shares in accordance with
the terms of the Merger Agreement;
   

               5. Giga-tronics has no plan or intention to cause ASCOR to issue
additional shares of stock after the Merger that would result in Giga-tronics
losing Control of ASCOR;
    

               6. Giga-tronics has no plan or intention to reacquire any of its
stock issued pursuant to the Merger;

               7. Except for transfers described in both Section 368(a)(2)(C) of
the Internal Revenue Code of 1986, as amended (the "Code"), and Treasury
Regulation Section 1.368-2(j)(4), Giga-tronics has no current plan or intention
to (i) liquidate ASCOR; (ii) merge ASCOR with or into another corporation
including Giga-tronics or its affiliates; (iii) sell, distribute or otherwise
dispose of the capital stock of ASCOR; or (iv) cause ASCOR to sell or otherwise
dispose of any of its assets (or any assets acquired from Sub) except for
dispositions made in the ordinary course of business or payment of expenses
incurred by ASCOR pursuant to the Merger (including payments made with respect
to dissenting shareholders and fractional shares);

               8. In the Merger, Sub will have no liabilities assumed by ASCOR
and will not transfer to ASCOR any assets subject to liabilities;

               9. Giga-tronics intends that, following the Merger, the historic
business of ASCOR will be continued;

               10. Neither Giga-tronics nor any current or former subsidiary of
Giga-tronics owns, or has owned during the past five (5) years, directly or
indirectly, any shares of ASCOR capital stock, or the right to acquire or vote
any such shares (except such rights as are granted in the Agreement);

               11. Giga-tronics is not an investment company within the meaning
of Sections 368(a)(2)(F)(iii) and (iv) of the Code;

               12. No shareholder of ASCOR is acting as agent for Giga-tronics
in connection with the Merger or approval thereof, and Giga-tronics will not
reimburse any ASCOR shareholder for ASCOR capital stock such shareholder may
have purchased or for other obligations such shareholder may have incurred;

               13. Neither Giga-tronics nor Sub is under the jurisdiction of a
court in a Title 11 or similar case within the meaning of Section 368(a)(3)(A)
of the Code;

               14. Giga-tronics has no knowledge of any plan or intention on the
part of ASCOR's shareholders (a "Plan") to engage in a sale, exchange, transfer,
distribution, pledge, disposition or any other transaction which results in a
reduction in the risk of ownership or a direct or indirect disposition (a
"Sale") of shares of Giga-tronics Common Stock to be issued to such shareholders
in the Merger, which shares would have an aggregate fair market value, as of the
Effective Date of the Merger, in excess of fifty percent (50%) of the aggregate
fair market value, immediately prior to the Merger, of all outstanding shares of
ASCOR capital stock. For purposes of this paragraph, shares of ASCOR capital
stock (or the portion thereof) (i) with respect to which a ASCOR shareholder
receives consideration in the Merger other than Giga-tronics Common Stock
(including, without limitation, cash received as a result of the exercise of
dissenters' rights and cash received in lieu of fractional shares of
Giga-tronics Common Stock) and/or (ii) with respect to which a Sale occurs prior
to and in contemplation of the Merger shall be considered shares of outstanding
ASCOR capital stock exchanged for Giga-tronics Common Stock in the Merger and
then disposed of pursuant to a Plan;

               15. The payment of cash in lieu of fractional shares of
Giga-tronics is solely for the purpose of avoiding the expense and inconvenience
to Giga-tronics of issuing fractional shares and does not represent separately
bargained-for consideration. The

total cash consideration that will be paid in the Merger to ASCOR shareholders
in lieu of fractional shares of Giga-tronics Common Stock will not exceed one
percent (1%) of the total consideration that will be issued in the Merger to
ASCOR shareholders in exchange for their shares of ASCOR capital stock. The
fractional share interests of each ASCOR shareholder will be aggregated and no
ASCOR shareholder will receive cash in an amount greater than the value of one
full share of Giga-tronics Common Stock;

               16. Except with respect to payments of cash to dissenting ASCOR
shareholders and payments of cash in lieu of fractional shares of Giga-tronics
Common Stock, one hundred percent (100%) of the ASCOR capital stock outstanding
immediately prior to the Merger will be exchanged solely for Giga-tronics Common
Stock. Thus, except as set forth in the preceding sentence, Sub and Giga-tronics
intend that no consideration be paid or received (directly or indirectly,
actually or constructively) for ASCOR capital stock other than Giga-tronics
Common Stock;

               17. At the Effective Time of the Merger, the fair market value of
the Giga-tronics Common Stock received by each ASCOR shareholder will be
approximately equal to the fair market value of the ASCOR capital stock
surrendered in exchange therefor, and the aggregate consideration received by
ASCOR shareholders in exchange for their ASCOR capital stock will be
approximately equal to the fair market value of all of the outstanding shares of
ASCOR capital stock immediately prior to the Merger;

               18. No shares of Sub have been or will be used as consideration
or issued to shareholders of ASCOR pursuant to the Merger;

               19. Giga-tronics, ASCOR, Sub and the shareholders of ASCOR will
each pay separately its or their own expenses in connection with the Merger;

               20. There is no intercorporate indebtedness existing between
Giga-tronics and ASCOR or between Sub and ASCOR that was issued, acquired or
will be settled at a discount as a result of the Merger, and Giga-tronics will
assume no liabilities of ASCOR or any ASCOR shareholder in connection with the
Merger;

               21. The terms of the Agreement and all other agreements entered
into in connection therewith are the product of arm's-length negotiations;

               22. None of the compensation received by any
shareholder-employees of ASCOR will be separate consideration for, or allocable
to, any of their shares of ASCOR capital stock; none of the shares of
Giga-tronics Common Stock received by any shareholder-employees of ASCOR will be
separate consideration for, or allocable to, any employment agreement or any
covenants not to compete; and the compensation paid to

any shareholder-employees of ASCOR will be for services actually rendered and
will be commensurate with amounts paid to third parties bargaining at arm's
length for similar services;

               23. No "poison pill" or similar rights will be associated with
the Giga-tronics Common Stock on or prior to the date of the Merger;

               24. With respect to each instance, if any, in which shares of
ASCOR capital stock have been purchased by a shareholder of Giga-tronics (a
"Shareholder") during the Pre-Merger Period (a "Stock Purchase"): (i) the Stock
Purchase was made by such Shareholder on its own behalf and with its own funds
and not as a representative, or for the benefit, of Giga-tronics; (ii) the
purchase price paid by such Shareholder pursuant to the Stock Purchase was the
product of arm's-length negotiations, was funded by such Shareholder's own
assets, and was not advanced, and will not be reimbursed, either directly or
indirectly, by Giga-tronics; (iii) at no time was such Shareholder or any other
party required or obligated to surrender to Giga-tronics the ASCOR capital stock
acquired in the Stock Purchase, and neither such Shareholder nor any other party
will be required to surrender to Giga-tronics the Giga-tronics Common Stock for
which such shares of ASCOR capital stock will be exchanged in the Merger; and
(iv) the Stock Purchase was not a formal or informal condition to consummation
of the Merger and was entered into solely to satisfy the separate interests of
such Shareholder and the seller;

               25. Each of the representations made by Giga-tronics and Sub in
the Agreement and any other documents associated therewith is true and accurate;
and

               26. The undersigned is authorized to make all of the
representations set forth herein on behalf of Giga-tronics and Sub.


B.      RELIANCE BY YOU IN RENDERING OPINION; LIMITATIONS ON YOUR
        OPINION

               Re:    Merger pursuant to the Agreement and Plan of
                      Reorganization (the "Agreement") dated May 2, 1996, among
                      Giga-tronics Incorporated, a California corporation
                      ("Giga-tronics"), ASCOR, Inc., a California corporation
                      ("ASCOR") and ASCOR Acquisition Corp., a California
                      corporation ("Sub")

Ladies and Gentlemen:

               This letter is supplied to you in connection with your rendering
of an opinion pursuant to Section 8.03(b) of the Agreement regarding certain
federal income tax consequences of the Merger. Unless otherwise indicated,
capitalized terms not defined herein have the meanings set forth in the
Agreement.

A.      REPRESENTATIONS

               On behalf of ASCOR, the undersigned hereby certifies and
represents that the following facts are now true and will continue to be true
through the Effective Date of the Merger:

               1. Pursuant to the Merger, Sub will merge with and into ASCOR,
and ASCOR will acquire all of the assets and liabilities of Sub. At least ninety
percent (90%) of the fair market value of the net assets and at least seventy
percent (70%) of the fair market value of the gross assets held by ASCOR
immediately prior to the Merger will continue to be held by ASCOR immediately
after the Merger. For the purpose of determining the percentage of ASCOR's net
and gross assets held by it immediately following the Merger, the following
assets will be treated as property held by ASCOR immediately prior but not
subsequent to the Merger: (i) assets disposed of by ASCOR prior to or subsequent
to the Merger and in contemplation thereof (including, without limitation, any
asset disposed of by ASCOR, other than in the ordinary course of business,
pursuant to a plan or intent existing during the period ending on the Effective

                                                                          Page 2




Date of the Merger and beginning with the commencement of negotiations (whether
formal or informal) with Giga-tronics regarding the Merger (the "Pre-Merger
Period")), (ii) assets used by ASCOR to pay other expenses or liabilities
incurred in connection with the Merger and (iii) assets used to make
distribution, redemption or other payments in respect of ASCOR capital stock or
rights to acquire such stock (including payments to dissenters) that are made in
contemplation of the Merger or related thereto;

               2. ASCOR has made no transfer of any of its assets (including any
distribution of assets with respect to, or in redemption of, stock) in
contemplation of the Merger or during the Pre-Merger Period other than (i) in
the ordinary course of business and (ii) payments for expenses incurred in
connection with the Merger;

               3. ASCOR is participating in the Merger for good and valid
business reasons and not for tax purposes;

               4. At the time of the Merger, except as specified in, or
disclosed in the Agreement or in a schedule or exhibit to, the Agreement, ASCOR
will have no outstanding warrants, options or convertible securities nor any
other type of right outstanding pursuant to which any person could acquire
shares of ASCOR capital stock or any other equity interest in ASCOR;

               5. In the Merger, shares of ASCOR capital stock representing
"Control" of ASCOR will be exchanged solely for voting stock of Giga-tronics; at
the time of the Merger, there will exist no rights to acquire ASCOR capital
stock or to vote (or restrict or otherwise control the vote of) ASCOR capital
stock which, if exercised, could affect Giga-tronics' acquisition and retention
of Control of ASCOR. For purposes of this paragraph, shares of ASCOR capital
stock exchanged in the Merger for cash and other property (including, without
limitation, cash paid to dissenters and cash paid in lieu of fractional shares
of Giga-tronics Common Stock) will be treated as ASCOR capital stock outstanding
on the date of the Merger but not exchanged for voting stock of Giga-tronics. As
used herein, "Control" of a corporation shall consist of ownership of stock
possessing at least eighty percent (80%) of the total combined voting power of
all classes of stock entitled to vote and at least eighty percent (80%) of the
total number of shares of all other classes of stock of the corporation. For
purposes of determining Control, a person shall not be considered to own voting
stock if rights to vote such stock (or to restrict or otherwise control the
voting of such stock) are held by a third party (including a voting trust) other
than an agent of such person;

               6. ASCOR has no obligation, understanding, agreement or intention
to issue additional shares of stock after the Merger that would result in
Giga-tronics losing Control of ASCOR;

                                                                          Page 3





               7. The liabilities of ASCOR have been incurred by ASCOR in the
ordinary course of its business;

               8. The fair market value of ASCOR's assets will, on the Effective
Date, exceed the aggregate liabilities of ASCOR;

               9. Other than shares of ASCOR capital stock or options to acquire
ASCOR capital stock issued as compensation to present or former service
providers (including, without limitation, employees and directors) of ASCOR in
the ordinary course of business, no issuances of ASCOR capital stock or rights
to acquire ASCOR capital stock have occurred or will occur during the Pre-Merger
Period other than pursuant to options, warrants or agreements outstanding prior
to the Pre-Merger Period or as otherwise specifically identified in the
Agreement;

               10. Cash or other property paid to employees of ASCOR during the
Pre-Merger Period has been or will be in the ordinary course of business or
pursuant to agreements entered into prior to the Pre-Merger Period;

               11. ASCOR is not and will not be on the Effective Date an
"investment company" within the meaning of Section 368(a)(2)(F)(iii) and (iv) of
the Code;

               12. ASCOR is not under the jurisdiction of a court in a Title 11
or similar case within the meaning of Section 368(a)(3)(A) of the Code;

               13. ASCOR has no knowledge of any plan or intention on the part
of ASCOR's shareholders (a "Plan") to engage in a sale, exchange, transfer,
distribution, pledge, disposition or any other transaction which results in a
reduction in the risk of ownership or a direct or indirect disposition (a
"Sale") of shares of Giga-tronics Common Stock to be issued to such shareholders
in the Merger, which shares would have an aggregate fair market value, as of the
Effective Date of the Merger, in excess of fifty percent (50%) of the aggregate
fair market value, immediately prior to the Merger, of all outstanding shares of
ASCOR capital stock. For purposes of this paragraph, shares of ASCOR capital
stock (or the portion thereof) (i) with respect to which a ASCOR shareholder
receives consideration in the Merger other than Giga-tronics Common Stock
(including, without limitation, cash received as a result of the exercise of
dissenters' rights and cash received in lieu of fractional shares of
Giga-tronics Common Stock) and/or (ii) with respect to which a Sale occurs prior
to and in contemplation of the Merger shall be considered shares of outstanding
ASCOR capital stock exchanged for Giga-tronics Common Stock in the Merger and
then disposed of pursuant to a Plan;

                                                                          Page 4




               14. The payment of cash in lieu of fractional shares of
Giga-tronics is solely for the purpose of avoiding the expense and inconvenience
to Giga-tronics of issuing fractional shares and does not represent separately
bargained-for consideration. The total cash consideration that will be paid in
the Merger to ASCOR shareholders in lieu of fractional shares of Giga-tronics
Common Stock will not exceed one percent (1%) of the total consideration that
will be issued in the Merger to ASCOR shareholders in exchange for their shares
of ASCOR capital stock. The fractional share interests of each ASCOR shareholder
will be aggregated, and no ASCOR shareholder will receive cash in an amount
greater than the value of one full share of Giga-tronics Common Stock;

               15. Except with respect to payments of cash to dissenting ASCOR
shareholders and payments of cash in lieu of fractional shares of Giga-tronics
Common Stock, one hundred percent (100%) of the ASCOR capital stock outstanding
immediately prior to the Merger will be exchanged solely for Giga-tronics Common
Stock. Thus, except as set forth in the preceding sentence, ASCOR intends that
no consideration be paid or received (directly or indirectly, actually or
constructively) for ASCOR capital stock other than Giga-tronics Common Stock;

               16. At the Effective Date of the Merger, the fair market value of
the Giga-tronics Common Stock received by each ASCOR shareholder will be
approximately equal to the fair market value of the ASCOR capital stock
surrendered in exchange therefor, and the aggregate consideration received by
ASCOR shareholders in exchange for their ASCOR capital stock will be
approximately equal to the fair market value of all of the outstanding shares of
ASCOR capital stock immediately prior to the Merger;

               17. No shares of Sub have been or will be used as consideration
or issued to shareholders of ASCOR pursuant to the Merger;

               18. Giga-tronics, ASCOR, Sub and the shareholders of ASCOR will
each pay separately its or their own expenses in connection with the Merger;

               19. There is no intercorporate indebtedness existing between
Giga-tronics and ASCOR or between Sub and ASCOR that was issued, acquired or
will be settled at a discount as a result of the Merger, and Giga-tronics will
assume no liabilities of ASCOR or any ASCOR shareholder in connection with the
Merger;

               20. The terms of the Agreement and all other agreements entered
into in connection therewith are the product of arm's-length negotiations;

               21. None of the compensation received by any
shareholder-employees of ASCOR will be separate consideration for, or allocable
to, any of their shares of

ASCOR capital stock; none of the shares of Giga-tronics Common Stock received by
any shareholder-employees of ASCOR will be separate consideration for, or
allocable to, any employment agreement or any covenants not to compete; and the
compensation paid to any shareholder-employees of ASCOR will be for services
actually rendered and will be commensurate with amounts paid to third parties
bargaining at arm's length for similar services;

               22. No direct or indirect subsidiary of ASCOR owns any shares of
ASCOR capital stock;

               23. No "poison pill" or similar rights will be associated with
shares of ASCOR capital stock on or prior to the date of the Merger;

               24. With respect to each instance, if any, in which shares of
ASCOR capital stock have been purchased by a shareholder of Giga-tronics (a
"Shareholder") during the Pre-Merger Period (a "Stock Purchase"): (i) to the
best knowledge of ASCOR, (A) the Stock Purchase was made by such Shareholder on
its own behalf and with its own funds, rather than as a representative, or for
the benefit, of Giga-tronics, (B) the Stock Purchase was entered into solely to
satisfy the separate interests of such Shareholder and the seller and (C) the
purchase price paid by such Shareholder pursuant to the Stock Purchase was the
product of arm's-length negotiations and (ii) the Stock Purchase was not a
formal or informal condition to consummation of the Merger;

               25. Each of the representations made by ASCOR in the Agreement
and any other documents associated therewith is true and accurate; and

               26. The undersigned is authorized to make all of the
representations set forth herein on behalf of ASCOR.


B.      RELIANCE BY YOU IN RENDERING OPINION;
        LIMITATIONS ON YOUR OPINION

on the representations set forth herein and on the statements contained in the

                         RESTATED 1990 STOCK OPTION PLAN

               AS RESTATED JULY 23, 1992 AND AMENDED MAY 17, 1994
<PAGE>   2
                                   ARTICLE ONE

                               GENERAL PROVISIONS

        I.    PURPOSES OF THE PLAN

              A.   This Restated 1990 Stock Option Plan (the "Plan"), as 
restated effective July 23, 1992 and amended May 17, 1994, is intended to
promote the interests of Giga-tronics Incorporated, a California corporation
(the "Company"), by providing a method whereby the Company's employees are to be
offered equity incentives intended to encourage such individuals to acquire a
proprietary interest, or otherwise increase their proprietary interest, in the
Company and to continue to render services to the Company or its parent or
subsidiary corporations.

              B.   For purposes of the Plan, the following definitions shall be
in effect:

                   BOARD: the Company's Board of Directors.

                   COMMON STOCK: The Common Stock issuable under the Plan shall
         be shares of the Company's common stock, no par value.

                   DISABILITY: The permanent incapacity of an individual, by
         reason of physical or mental illness, to perform his/her usual duties 
         for the Company. Disability shall be determined by the Committee after
         consideration of such medical evidence as it may require.

                  EMPLOYEE: An individual shall be considered to be an
         Employee for so long as such individual remains in the employ
         of the Company or one or more of its parent or subsidiary
         corporations.

                   FAIR MARKET VALUE: The Fair Market Value per share of Common
         Stock on any relevant date under the Plan shall be the mean between the
         highest bid and lowest asked prices (or, if such information is
         available, the closing selling price) per share of Common Stock on such
         date in the over-the-counter market, as such prices are reported by the
         National Association of Securities Dealers on the Nasdaq National
         Market (or any successor system). Should the Common Stock become traded
         on a national securities exchange, then the Fair Market Value per share
         shall be the closing selling price on such exchange on the date in
         question, as such price is quoted on the composite tape of transactions
         on such exchange. If there is no reported sale of Common Stock on the
         over-the-
<PAGE>   3
         counter market (or national securities exchange) on the date in
         question, then the Fair Market Value shall be the mean between the
         highest bid and lowest asked prices (or closing selling price) on the
         last preceding date for which such quotations exist.

                   PARENT: A corporation shall be deemed to be a parent of the 
         Company if it is a corporation (other than the Company) in an unbroken
         chain of corporations ending with the Company, provided each such
         corporation in the unbroken chain (other than the Company) owns, at the
         time of the determination, stock possessing fifty percent (50%) or more
         of the total combined voting power of all classes of stock in one of
         the other corporations in such chain.

                   SECTION 16(B) INSIDER: An individual shall be considered to 
         be a Section 16(b) Insider on any relevant date under the Plan if such
         individual is at the time subject to the short-swing profit
         restrictions of Section 16(b) of the Securities Exchange Act of 1934 by
         reason of his or her affiliation with the Company.

                   SERVICE: An individual shall be deemed to be in the Service
         of the Company for so long as such individual (i) renders service on a
         periodic basis to the Company or one or more of its parent or
         subsidiary corporations as an Employee or (ii) serves as a non-employee
         member of the Company's Board of the Directors.

                   SUBSIDIARY: A corporation shall be deemed to be a subsidiary
         of the Company if it is one of the corporations (other than the
         Company) in an unbroken chain of corporations beginning with the
         Company, provided each such corporation (other than the last
         corporation in the unbroken chain) owns, at the time of determination,
         stock possessing fifty percent (50%) or more of the total combined
         voting power of all classes of stock in one of the other corporations
         in such chain. For purposes of all non-statutory option grants under
         Article Two and all Corporate Transaction provisions of the Plan, the
         term "subsidiary" shall also include any partnership, joint venture or
         other business entity of which the Company owns, directly or indirectly
         through another subsidiary corporation, more than a fifty percent (50%)
         interest in voting power, capital or profits.

              C.   Stock option grants made to any individual under the Plan 
shall not in any way affect, limit or restrict such individual's eligibility to
participate in any other stock plan or


                                       2.
<PAGE>   4
other compensation or benefit plan, arrangement or practice now or hereafter
maintained by the Company or any parent or subsidiary corporation.

         II.  ADMINISTRATION OF THE PLAN

              A.   The Plan shall be administered by a committee (the
"Committee") of two (2) or more Board members appointed by the Board. A Board
member shall be eligible to serve on such Committee only if such individual
shall not have received, at any time during the twelve (12)-month period
preceding the date such individual is to commence Committee service, any awards
or grants under this Plan (other than an automatic option grant under the
provisions of this Plan in effect prior to the May 1994 amendment) or under any
other stock option, stock appreciation, stock bonus or other stock plan of the
Company or its parent or subsidiary corporations. The Board shall have the
authority to fill any and all vacancies on the Committee, however caused.

              B.   Subject to the express provisions of the Plan, the Committee
shall have plenary authority:

                 (i)     to make discretionary option grants to Employees under
the Discretionary Option Grant Program set forth in Article Two;

                (ii)     to interpret the Plan, to prescribe, amend and rescind
rules and regulations relating to it, and to make all other determinations
deemed necessary or advisable in administering the Plan; and

               (iii)     to change the terms and conditions of any outstanding
option grant under the Discretionary Option Grant Program, provided such action
does not, without the consent of the holder, adversely affect the rights and
obligations such individual may have under the Plan or the outstanding grant.

              C.  Determinations of the Committee on all matters relating to the
Plan and any option grants or stock issuances made hereunder shall be final,
binding and conclusive on all persons having any interest in the Plan or any
options granted or shares issued under the Plan.

         III. PLAN STRUCTURE AND ELIGIBILITY

              A.   The Plan as amended May 1994 shall consist only of the
Discretionary Option Grant Program set forth in Article Two. The terms and
provisions of Articles One and Five of the Plan shall also be applicable to such
program.

                                       3.
<PAGE>   5
              B.   The individuals eligible to participate in the Discretionary
Option Grant Program ("Optionees") shall be limited to Employees (including
officers and directors) of the Company or its parent or subsidiary corporations.
Non-employee members of the Board shall not be eligible to participate in the
Discretionary Option Grant Program.

              C.   Members of the Committee shall not, during their period of
Committee service, participate in the Discretionary Option Grant Program of
Article II of this Plan or in any other stock option, stock bonus, stock
purchase or stock plan of the Company or its parent or subsidiary corporations.

         IV.  STOCK SUBJECT TO THE PLAN

              A.   The Common Stock issuable under the Plan shall be made
available either from authorized but unissued shares of Common Stock or from
shares of Common Stock reacquired by the Company on the open market. The
aggregate number of shares of Common Stock issuable over the term of this Plan
shall not exceed 400,000 shares (subject to adjustment from time to time in
accordance with paragraph C. below).

              B.   Should an option expire or terminate for any reason prior to
exercise or surrender in full (including options cancelled in accordance with
the cancellation-regrant provisions of Article Two below), the shares subject to
the portion of the option not so exercised or surrendered shall be available for
subsequent option grants under the Plan. Shares subject to any stock
appreciation rights exercised in accordance with the Stock Appreciation Right
provisions of Articles Two and all share issuances under the Plan shall reduce
on a share-for-share basis the number of shares of Common Stock available for
subsequent option grants under this Plan. If the exercise price of an
outstanding option under the Plan is paid with shares of Common Stock or if
shares of Common Stock otherwise issuable under the Plan are withheld by the
Company in satisfaction of the withholding taxes incurred in connection with the
exercise of an outstanding option under the Plan, then the number of shares of
Common Stock available for issuance under the Plan shall be reduced by the gross
number of shares for which the option is exercised, and not by the net number of
shares of Common Stock actually issued.

              C.   In the event any change is made to the Common Stock issuable
under the Plan by reason of any stock dividend, stock split, combination of
shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without receipt of consideration, then appropriate adjustments
shall be made to (i)

                                       4.
<PAGE>   6
the maximum number and/or class of shares issuable under this Plan, to reflect
the effect of such change upon the Company's capital structure, (ii) the class
and/or maximum number of securities for which stock options and separately
exercisable stock appreciation rights may be granted to any one participant in
the aggregate after April 30, 1994 and (iii) the number and/or class of shares
and the exercise price per share of the stock subject to each outstanding option
in order to preclude the dilution or enlargement of benefits thereunder. The
adjustments determined by the Committee shall be final, binding and conclusive.

              D.   In the event that (i) the Company is the surviving entity in
any Corporate Transaction which does not result in the termination of
outstanding options pursuant to the Corporate Transaction provisions of the Plan
or (ii) the outstanding options under the Plan are to be assumed in connection
with such Corporate Transaction, then each such continuing or assumed option
shall, immediately after such Corporate Transaction, be appropriately adjusted
Ito apply and pertain to the number and class of securities which would be
issuable, in consummation of such Corporate Transaction, to an actual holder of
the same number of shares of Common Stock as are subject to such option
immediately prior to such Corporate Transaction. Appropriate adjustments shall
also be made to the exercise price payable per share, provided the aggregate
option price shall remain the same, and to the number and class of securities
which remain issuable under this Plan.

              E.   In no event may any one individual participating in the Plan 
be granted stock options and separately exercisable stock appreciation rights
for more than 200,000 shares in the aggregate over the remaining term of the
Plan, subject to adjustment from time to time in accordance with paragraph C.
above. For purposes of such limitation, no stock options or stock appreciation
rights granted prior to May 1, 1994 shall be taken into account.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM


         I.   TERMS AND CONDITIONS OF OPTIONS

              A.   The Committee shall have plenary authority (subject to the
express provisions of the Plan) to determine which Employees are to be granted
options under this Discretionary Option Grant Program, the number of shares to
be covered by each such option, the status of the granted option as either an
incentive stock option which meets the requirements of Section 422 of the
Internal Revenue Code ("Incentive Option") or a non-statutory option not
intended to meet such requirements, the time or times at which such option is to
become exercisable and the maximum term for which the option is to remain
outstanding.

              B.   The granted options shall be evidenced by instruments in such
form as the Committee shall from time to time approve; provided, however, that
each such instrument shall comply with and incorporate the terms and conditions
specified below.

              1.   Option Price.

              a.   The option price per share shall be fixed by the Committee, 
but in no event shall the option price per share be less than eighty percent
(80%) of the Fair Market Value per share of Common Stock on the date of the
option grant.

              b.   The option price shall become immediately due upon exercise 
of the option and shall, subject to the loan provisions of this Article Two, be
payable in one of the alternative forms specified below:

                   (A)  full payment in cash or check made payable to the 
         Company's order; or

                   (B)  full payment in shares of Common Stock held by the 
         Optionee for the requisite period necessary to avoid a charge to the 
         Company's reported earnings and valued at Fair Market Value on the
         Exercise Date (as such term is defined below); or


                                       6.
<PAGE>   8
                   (C) full payment in a combination of shares of Common Stock
         held by the Optionee for the requisite period necessary to avoid a 
         charge to the Company's reported earnings and valued at Fair Market
         Value on the Exercise Date and cash or check made payable to the
         Company's order; or

                   (D)  full payment through a sale and remittance procedure
         pursuant to which the Optionee (I) shall provide irrevocable written
         instructions to a designated brokerage firm to effect the immediate 
         sale of the purchased shares and remit to the Company, out of the sale
         proceeds available on the settlement date, sufficient funds to cover
         the aggregate option price payable for the purchased shares plus all
         applicable Federal and State income and employment taxes required to be
         withheld by the Company by reason of such purchase and (II) shall
         concurrently provide written directives to the Company to deliver the
         certificates for the purchased shares directly to such brokerage firm
         in order to complete the sale transaction.

              c.   For purposes of subparagraph b. above, the Exercise Date 
shall be the date on which written notice of the option exercise is delivered to
the Company. Except to the extent the sale and remittance procedure is utilized
in connection with the option exercise, payment of the option price for the
purchased shares must accompany the exercise notice.

              2.   Term and Exercise of Options.

              a.   Each option granted under this Discretionary Option Grant
Program shall be exercisable in one or more installments over the Optionee's
period of Service as shall be determined by the Committee and shall be set forth
in the instrument evidencing such option; provided, however, that (i) no such
option shall become exercisable in whole or in part within the first six (6)
months after the grant date, except as otherwise provided in Section III of this
Article Two and (ii) no such option shall have a term in excess of ten (10)
years from the grant date.

              b.   During the lifetime of the optionee, the option, together 
with any stock appreciation rights pertaining to such option, shall be
exercisable only by the optionee and shall not be assignable or transferable by
the optionee other than a transfer of the option effected by will or by the laws
of descent and distribution following the optionee's death.


                                       7.
<PAGE>   9
              3.   Termination of Service.

              a.   Should an Optionee cease to continue in Service for any 
reason (other than termination set forth in subparagraph c. below) while the
holder of one or more outstanding options under this Discretionary Option Grant
Program, then such options shall not be exercisable at any time after the
earlier of (i) the specified expiration date of the option term or (ii) the
expiration of the limited period of time (not to exceed twelve (12) months after
the Optionee's cessation of Service) specified by the Committee in the option
agreement. Each such option shall, during the applicable period following
cessation of Service, be exercisable only to the extent of the number of shares
(if any) in which the Optionee is vested on the date of such cessation of
Service.

              b.   Any option granted to an Optionee under this Discretionary
Option Grant Program and outstanding in whole or in part on the date of the
Optionee's death may be subsequently exercised, but only to the extent of the
number of shares (if any) in which the Optionee is vested on the date of his/her
cessation of Service (less any shares subsequently purchased by the optionee
prior to death), by the personal representative of the Optionee's estate or by
the person or persons to whom the option is transferred pursuant to the
Optionee's will or in accordance with the laws of descent and distribution. Any
such exercise must occur prior to the earlier of (i) the expiration date of the
option term or (ii) the expiration of the limited period of time (not to exceed
twelve (12) months following the Optionee's cessation of Service) specified by
the Committee in the option agreement.

              c.   If the Optionee's Service is terminated for any of the
following reasons, then all outstanding options granted the Optionee under this
Discretionary Option Grant Program shall immediately terminate and cease to be
exercisable immediately upon such termination of Service:

                   (1)  Optionee's intentional misconduct or continuing gross
         neglect of duties which materially and adversely affects the business
         and operations of the Company or any parent or subsidiary corporation
         employing Optionee;

                   (2)  Optionee's unauthorized use or disclosure (or attempt
         thereat) of confidential information or trade secrets of the Company or
         its parent or subsidiary corporations; or


                                       8.
<PAGE>   10
                   (3) Optionee's commission of an act involving embezzlement,
         theft, fraud, falsification of records, destruction of property or
         commission of a crime or other offense involving money or other 
         property of the Company or any parent or subsidiary corporation
         employing Optionee.

                   The reasons for termination of Optionee's Service set forth
in this subparagraph c. are not intended to be, and are not inclusive of, all
acts or omissions which the Company may deem to constitute misconduct or other
grounds for terminating the Optionee's (or any other individual's) Service.

              d.   The Committee shall have complete discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to establish as a provision applicable to the exercise of one or
more options granted under this Discretionary Option Grant Program that during
the limited period of exercisability following cessation of Service, the option
may be exercised not only with respect to the number of shares in which the
Optionee is vested at the time of such cessation of Service but also with
respect to one or more subsequent installments of purchasable shares in which
the Optionee would otherwise have vested had the Optionee continued in Service.
In addition, the Committee shall have similar discretion to extend the period of
time during which the option is to remain exercisable following the optionee's
cessation of Service, but in no event shall such period extend beyond the
specified expiration date of the option term.

              4.   Shareholder Rights. An option holder shall have none of the
rights of a shareholder with respect to any shares covered by the option until
such individual shall have exercised the option, paid the option price and
satisfied all other conditions precedent to the issuance of certificates for the
purchased shares.

         II.  STOCK APPRECIATION RIGHTS

              A.   Each Section 16(b) Insider shall have a limited stock
appreciation right ("Limited Right") in tandem with each option grant (whether
an Incentive Option or a non-statutory option) made to such individual under
this Discretionary Option Grant Program. The Limited Right shall entitle the
Section 16(b) Insider to surrender the underlying option in connection with a
Change in Control (as defined below) for an appreciation distribution from the
Company in an amount equal to the excess of (I) the Change in Control Price (as
defined below) of the number of shares in which the Section 16(b) Insider is at
the time vested under the surrendered option over (II) the aggregate option
price payable for such vested shares.

                                       9.
<PAGE>   11
              B.  The terms and conditions applicable to each such Limited 
Right shall be as follows:

                  1.   The option may only be surrendered during the thirty
         (30)-day period following the Change in Control. However, the Section
         16(b) Insider may not surrender any option which (I) has not been
         outstanding for at least six (6) months prior to the surrender date and
         (II) is not at the time exercisable for any vested shares.

                  2.   For purposes of calculating the appreciation 
         distribution payable by the Company on each surrendered option, the
         Change in Control Price per share of the vested Common Stock subject to
         the surrendered option shall be deemed to be equal to the greater of
         (a) the Fair Market Value per share on the option surrender date or (b)
         the highest reported price per share paid in effecting the Change in
         Control. However, if the option is an Incentive Option, then the Change
         in Control Price of the vested shares subject to the surrendered option
         shall not exceed the value per share determined under clause (a) above.

                  3.   The appreciation distribution shall be made entirely in
         cash, and neither the approval of the Committee nor the consent of the
         Board shall be required in connection with such surrender and
         distribution. The shares of Common Stock subject to each surrendered
         option shall not be available for subsequent issuance under this Plan.

                  4.   A Change in Control shall be deemed to occur in the 
         event any of the following transactions is effected:

                      (i)     the acquisition by a person or group of related
                  persons, other than the Company or any person controlling,
                  controlled by or under common control with the Company, of
                  beneficial ownership (as determined pursuant to the provisions
                  of Rule 13d-3 under the Securities Exchange Act of 1934, as
                  amended) of securities of the Company representing thirty
                  percent (30%) or more of the combined voting power of the
                  Company's then outstanding securities pursuant to a
                  transaction or series of related transactions which the Board
                  does not approve; or


                                       10.
<PAGE>   12
                      (ii)    the first date within any period of twelve (12)
                  consecutive months or less on which there is effected any
                  change in the composition of the Board such that the majority
                  of the Board (determined by rounding up to the next whole
                  number) ceases to be comprised of individuals who either (A)
                  have been members of the Board continuously since the
                  beginning of such period or (B) have been elected or nominated
                  for election as Board members during such period by at least a
                  majority of the Board members described in clause (A) who were
                  still in office at the time such election or nomination was
                  approved by the Board.

         III. CORPORATE TRANSACTION/CHANGE IN CONTROL

              A.   Upon the occurrence of any of the following transactions (a
"Corporate Transaction") to which the Company is a party and for which the
approval of the Company's shareholders is obtained:

                   (i)     a merger or acquisition in which the Company is not
          the surviving entity, except for a transaction the principal purpose
          of which is to change the State of the Company's incorporation,

                  (ii)     the sale, transfer or other disposition of all or
         substantially all of the assets of the Company to any entity other than
         a parent or subsidiary of the Company, or

                  (iii)    any reverse merger in which the Company is the 
         surviving entity but in which fifty percent (50%) or more of the
         Company's outstanding voting stock is transferred to holders different
         from those who held the stock immediately prior to such merger,

              the exercisability of each option outstanding under this
Discretionary Option Grant Program (whether or not such option has been
outstanding for a period of six (6) months) shall be automatically accelerated
so that each such option shall, immediately prior to the specified effective
date for the Corporate Transaction, become fully exercisable with respect to the
total number of shares of Common Stock purchasable under such option and may be
exercised for all or any portion of such shares. However, the instrument
evidencing an option grant under this Discretionary Option Grant Program may
provide that such option shall not be so


                                       11.
<PAGE>   13
accelerated if and to the extent: (i) such option is, in connection with the
Corporate Transaction, either to be assumed by the successor corporation or
parent thereof or to be replaced with a comparable option to purchase shares of
the capital stock of the successor corporation or parent thereof, or (ii) such
option is to be replaced by a comparable cash incentive program of the successor
corporation based on the value of the option at the time of the Corporate
Transaction, or (iii) the acceleration of such option is subject to other
applicable limitations imposed by the Committee at the time of grant. The
determination of comparability under clause (i) or (ii) above shall be made by
the Committee, and its determination shall be final, binding and conclusive. The
Committee shall have the discretion, exercisable either in advance of any
actually-anticipated Corporate Transaction or at the time of an actual Corporate
Transaction, to provide (upon such terms and conditions as it may deem
appropriate) for either the automatic acceleration of one or more assumed or
replaced options which are not otherwise to be accelerated in connection with
the Corporate Transaction or the automatic vesting of any cash incentive
programs implemented in replacement of such options, in the event the Optionee's
employment should subsequently terminate within a designated period following
the effective date of such Corporate Transaction.

              B. Immediately following the consummation of the Corporate
Transaction, all outstanding options under this Discretionary Option Grant
Program shall, to the extent not previously exercised or assumed by the
successor corporation or its parent company, terminate and cease to be
outstanding.

              C. Upon the occurrence of any of the following transactions (a
"Change in Control"):

                  (i)   the acquisition by a person or group of related persons,
         other than the Company or any person controlling, controlled by or
         under common control with the Company, of beneficial ownership (as
         determined pursuant to the provisions of Rule 13d-3 under the
         Securities Exchange Act of 1934, as amended) of securities of the
         Company representing thirty percent (30%) or more of the combined
         voting power of the Company's then outstanding securities pursuant to a
         transaction or series of related transactions which the Board does not
         approve; or

                 (ii)   the first date within any period of twelve (12)
         consecutive months or less on which there is effected any change in the
         composition of the Board such that the majority of the Board
         (determined by rounding up


                                       12.
<PAGE>   14
         to the next whole number) ceases to be comprised of individuals who
         either (A) have been members of the Board continuously since the
         beginning of such period or (B) have been elected or nominated for
         election as Board members during such period by at least a majority of
         the Board members described in clause (A) who were still in office at
         the time such election or nomination was approved by the Board;

              the exercisability of each option outstanding under this
Discretionary Option Grant Program (whether or not such option has been
outstanding for a period of six (6) months) shall be automatically accelerated
so that each such option shall become exercisable, immediately prior to such
Change in Control, for the full number of shares purchasable under such option
and may be exercised for all or any portion of such shares at any time
thereafter until the expiration or sooner termination of the option term.
However, an outstanding option under this Discretionary Option Grant Program
shall not be so accelerated if and to the extent one or more limitations imposed
by the Committee at the time of grant preclude such acceleration upon a Change
in Control. The Committee shall have the discretion, exercisable either in
advance of any actually-anticipated Change in Control or at the time of an
actual Change in Control, to provide (upon such terms and conditions as it may
deem appropriate) for the automatic acceleration of one or more outstanding
options which are not otherwise to be accelerated upon a Change in Control, in
the event the Optionee's employment should subsequently terminate within a
designated period following the effective date of such Change in Control.

              D.   In the event a particular transaction qualifies as both a
Corporate Transaction and a Change in Control, the provisions of Section III.A
shall be controlling.

              E.   The grant of options under this Discretionary Option Grant
Program shall in no way affect the right of the Company to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.

         IV.  INCENTIVE OPTIONS

              A.   The terms and conditions specified below shall be applicable 
to all Incentive Options granted under this Discretionary Option Grant Program.
Options which are specifically designated as "non-statutory" options when issued
under this Discretionary Option Grant Program shall not be subject to such terms
and conditions.

                                       13.
<PAGE>   15
                  1. Option Price. The option price per share of the Common
         Stock subject to an Incentive Option shall in no event be less than one
         hundred percent (100%) of the Fair Market Value per share of Common
         Stock on the grant date.

                  2. 10% Stockholder. If any individual to whom an Incentive
         Option is to be granted pursuant to the provisions of this
         Discretionary Option Grant Program is on the grant date the owner of
         stock (as determined under Section 425(d) of the Internal Revenue Code)
         possessing 10% or more of the total combined voting power of all
         classes of stock of the Company or any one of its parent or subsidiary
         corporations (such person to be herein referred to as a 10%
         Stockholder), then (i) the option price per share shall not be less
         than one hundred and ten percent (110%) of the Fair Market Value per
         share of Common Stock on the grant date and (ii) the maximum term of
         the option shall not exceed five (5) years from the grant date.

                  3. Dollar Limitation. The aggregate fair market value
         (determined on the basis of the Fair Market Value in effect on the
         respective date or dates of grant) of the Common Stock for which one or
         more options granted to any Employee under this Plan (or any other
         option plan of the Company or its parent or subsidiary corporations)
         may for the first time become exercisable as incentive stock options
         under the Federal tax laws during any one calendar year shall not
         exceed the sum of One Hundred Thousand Dollars ($100,000). To the
         extent the Employee holds two or more such options which become
         exercisable for the first time in the same calendar year, the foregoing
         limitation on the exercisability thereof as incentive stock options
         under the Federal tax laws shall be applied on the basis of the order
         in which such options are granted.

              B.   Except as modified by the preceding provisions of this
Incentive Options section, all the provisions of this Discretionary Option Grant
Program shall be applicable to the Incentive Options granted hereunder.

         V.   CANCELLATION AND RE-GRANT OF OPTIONS

              A.   The Committee shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under this Discretionary Option
Grant Program and to grant in

                                       14.

substitution therefor new options under this Plan covering the same or different
numbers of shares of Common Stock but having an option price per share not less
than (i) eighty percent (80%) of the Fair Market Value per share of Common Stock
on the new grant date, or (ii) one hundred percent (100%) of such Fair Market
Value if the new option is to be an Incentive Option, or (iii) one hundred and
ten percent (110%) of such Fair Market Value if the new option is to be an
Incentive Option subject to the provisions of Section IV.A.2.

         VI.  LOANS OR GUARANTEE OF LOANS

              A.   The Committee may assist any Employee (including any officer
or director) in the exercise of one or more outstanding options under this
Discretionary Option Grant Program by (a) authorizing the extension of a loan to
such Employee from the Company, (b) permitting the Employee to pay the option
price for the purchased Common Stock in installments over a period of years or
(c) authorizing a guarantee by the Company of a third-party loan to the
Employee. The terms of any loan, installment method of payment or guarantee
(including the interest rate and terms of repayment) shall be established by the
Committee in its sole discretion. Loans, installment payments and guarantees may
be granted without security or collateral, but the maximum credit available to
the optionee shall not exceed the sum of (i) the aggregate option price of the
purchased shares plus (ii) any Federal and State income and employment tax
liability incurred by the Employee in connection with the exercise of the
option.

                                  MISCELLANEOUS

         I.   TAX WITHHOLDING

              A.   The Company's obligation to deliver shares or cash upon the
exercise or surrender of stock options or stock appreciation rights granted
under the Discretionary Option Grant Program shall be subject to the
satisfaction of all applicable Federal, State and local income and employment
tax withholding requirements.

              B.   The Committee may, in its discretion and upon such terms and
conditions as it may deem appropriate (including the applicable safe-harbor
provisions of SEC Rule 16b-3 or any successor rule or regulation) provide any or
all holders of outstanding option grants under the Discretionary Option Grant
Program with the election to have the Company withhold, from the shares of
Common Stock purchased or issued pursuant to such options, a portion of those
shares with an aggregate Fair Market Value equal to the designated percentage
(any multiple of 5% specified by the Optionee) of the Federal and State income
taxes ("Taxes") incurred in connection with their acquisition. In lieu of such
direct withholding, one or more Optionees may also be granted the right to
deliver shares of Common Stock to the Company in satisfaction of such Taxes. The
withheld or delivered shares shall be valued at the Fair Market Value on the
applicable determination date for such Taxes or such other date required by the
applicable safe-harbor provisions of SEC Rule 16b-3.

         II.  AMENDMENT OF THE PLAN

              A.   Except to the extent otherwise provided in this Article 
Three, the Board shall have the complete and exclusive authority to amend or
modify the Plan in any or all respects whatsoever. However, no such amendment or
modification shall, without the consent of the holders, adversely affect rights
and obligations with respect to any stock options or stock appreciation rights
at the time outstanding under the Plan.

              B.   The Board shall not, without the approval of the Company's
shareholders, (i) increase the maximum number of shares issuable under the Plan
or the number of shares for which any one individual participating in the Plan
may be granted stock options and separately exercisable stock appreciation
rights in the aggregate after April 30, 1994, except for permissible adjustments
in the event of a change in the corporate structure of the Company, (ii)
materially increase the benefits accruing to participants


                                       16.
<PAGE>   18
under the Plan or (iii) materially modify the eligibility requirements for
participation in the Plan.

         III. EFFECTIVE DATE AND TERM OF PLAN

              A.   The Plan was initially adopted by the Board on June 26, 1990
and approved by the Company's shareholders at the 1990 Annual Meeting. The
Committee may grant stock options under the Discretionary Option Grant Program
at any time prior to the date fixed herein for termination of the Plan.

              B.   The Board amended and restated the Plan effective May 8, 1991
to implement the automatic option grant program for certain non-employee Board
members and to conform the provisions of the Plan to recent changes in the SEC
rules under Section 16 of the Securities Exchange Act of 1934 applicable to
transactions effected under the Plan by Section 16(b) Insiders. The May 1991
restatement was approved by the Company's shareholders at the 1991 Annual
Meeting. The May 1991 restatement shall apply only to options granted under the
Plan from and after the May 8, 1991 effective date. Each option (together with
any related stock appreciation right) issued and outstanding under the Plan
immediately prior to such effective date shall continue to be governed by the
terms and conditions of the Plan (and the option agreement evidencing such
option and stock appreciation right) as in effect on the date such option was
previously granted, and nothing in the May 1991 restatement shall be deemed to
affect or otherwise modify the rights or obligations of the holders of such
options with respect to the acquisition of shares of Common Stock thereunder or
the exercise of their outstanding stock appreciation rights.

              C.   On July 23, 1992, the Board adopted a restatement of the Plan
to bring the Plan into compliance with recent SEC interpretive rulings under
Rule 16b-3, as amended May 1, 1991, under the Securities Exchange Act of 1934.
The July 1992 restatement shall apply only to options granted under the Plan
from and after the July 23, 1992 effective date. Each option (together with any
related stock appreciation right) issued and outstanding under the Plan
immediately prior to such effective date shall continue to be governed by the
terms and conditions of the Plan (and the option agreement evidencing such
option and stock appreciation right) as in effect on the date such option was
previously granted, and nothing in the July 1992 restatement shall be deemed to
affect or otherwise modify the rights or obligations of the holders of such
options with respect to the acquisition of shares of Common Stock thereunder or
the exercise of their outstanding stock appreciation rights.


                                       17.
<PAGE>   19
              D.   The sale and remittance procedure for the exercise of
outstanding options shall be available for all options granted under the Plan
after April 30, 1991 and for all non-statutory options outstanding under the
Plan on such date. The Committee may also allow such procedure to be utilized in
connection with one or more disqualifying dispositions of Incentive Option
shares effected after such date.

              E.   On May 17, 1994, the Board amended the Plan to increase the
number of shares of Common Stock issuable over the term of the Plan by an
additional 100,000 shares, and such amendment shall be submitted for shareholder
approval at the 1994 Annual Meeting. The 100,000-share increase became effective
immediately upon authorization by the Board, but no option granted on the basis
of such increase shall be exercisable unless and until the increase shall have
been approved by the Company's shareholders. If such shareholder approval is not
obtained at the 1994 Annual Meeting, then any options previously granted on the
basis of the 100,000-share increase shall terminate and no further options based
on such increase shall be granted. Those options granted under the Plan which
are not based on such increase shall remain outstanding in accordance with the
terms and conditions of the respective instruments evidencing such options,
whether or not the requisite shareholder approval is obtained. Subject to the
foregoing limitations, the Plan Administrator may grant options under the Plan
at any time before the date fixed herein for termination of the Plan. In
addition, the May 1994 amendment eliminated the automatic option grant program
previously in effect under the Plan for non-employee Board members, retroactive
to January 1, 1993.

              F.   The Plan shall in all events terminate upon the earlier of
(i) the tenth (10th) anniversary of the date of its adoption by the Board or
(ii) the date on which all shares available for issuance under the Plan shall
have been issued or cancelled pursuant to the exercise or surrender of stock
options and/or stock appreciation rights under the Plan. If the date of
termination is determined under clause (i) above, then any stock options and
stock appreciation rights at the time outstanding under the Plan shall continue
to have force and effect in accordance with the provisions of the instruments
evidencing such grants.

              G.   Options may be granted under this Plan to purchase shares of
Common Stock in excess of the number of shares then available for issuance under
the Plan, provided (i) an amendment to increase the maximum number of shares
issuable under the Plan is adopted by the Board prior to the initial grant of
any such option and within one year thereafter such amendment is approved by the
Company's shareholders and (ii) each option granted is not to

                   
                                       18.

become exercisable, in whole or in part, at any time prior to the obtaining of
such shareholder approval.

         IV.  MISCELLANEOUS PROVISIONS

              A.   Any cash proceeds received by the Company from the issuance
of shares hereunder shall be used for general corporate purposes.

              B.   The implementation of the Plan, the granting of any stock
option, and the issuance of Common Stock hereunder, shall be subject to the
Company's procurement of all approvals and permits required by regulatory
authorities having jurisdiction over the Plan, and the stock options granted
under it and the Common Stock issued pursuant to it.

              C.   Neither the action of the Company in establishing the Plan,
nor any action taken by the Board or the Committee hereunder, nor any provision
of the Plan itself shall be construed so as to grant any individual the right to
remain in the employ or service of the Company or any of its parent or
subsidiary corporations for any period of specific duration, and the Company (or
any parent or subsidiary retaining the services of such individual) may
terminate such individual's employment or service at any time and for any
reason, with or without cause.

              D.   Nothing contained in the Plan shall be construed to limit the
authority of the Company to exercise its corporate rights and powers, including
(without limitation) the right of the Company (a) to grant options for proper
corporate purposes otherwise than under this Plan to any Employee or other
person, firm or company or association or (b) to grant options to, or assume the
option of, any person in connection with the acquisition (by purchase, lease,
merger, consolidation or otherwise) of the business and assets (in whole or in
part) of any person, firm, company or association.

                             STOCK OPTION AGREEMENT

                                   WITNESSETH:

RECITALS

                  A.       The Board of Directors of the Company (the "Board")
has adopted the Company's Restated 1990 Stock Option Plan (the "Plan") for the
purpose of attracting and retaining the services of key employees (including
officers and directors) who contribute to the financial success of the Company
or its parent or subsidiary corporations.

                  B.       Optionee is an individual who is to render valuable
services to the Company or its parent or subsidiary corporations, and this
Agreement is executed pursuant to, and is intended to carry out the purposes of,
the Plan in connection with the Company's grant of a stock option to Optionee.

                  C.       For purposes of this Agreement, the following
definitions shall be in effect:

                           Employee: Optionee shall be considered to be an
         Employee for so long as such individual remains in the employ of the
         Company or one or more of its Parent or Subsidiary corporations.

                           Fair Market Value: The Fair Market Value per share of
         Common Stock on any relevant date under the Plan shall be the mean
         between the highest bid and lowest asked prices (or, if such
         information is available, the closing selling price) per share of
         Common Stock on such date in the over-the-counter market, as such
         prices are reported by the National Association of Securities Dealers
         through the NASDAQ system (or any successor system). Should the Common
         Stock become traded on a national securities exchange, then the Fair
         Market Value per share shall be the closing selling price on such
         exchange on the date in question, as such price is quoted on the
         composite tape of transactions on such exchange. If there is no
         reported sale of Common Stock on the over-the-counter market (or
         national securities exchange) on the date in question, then the Fair
         Market Value shall be the mean between the highest bid and lowest asked
         prices (or closing selling price) on the last preceding date for which
         such quotations exist.

                                       1.
<PAGE>   22
                           Parent: A corporation shall be deemed to be a Parent
         of the Company if it is a corporation (other than the Company) in an
         unbroken chain of corporations ending with the Company, provided each
         such corporation in the unbroken chain (other than the Company) owns,
         at the time of the determination, stock possessing fifty percent (50%)
         or more of the total combined voting power of all classes of stock in
         one of the other corporations in such chain.

                           Service: Optionee shall be deemed to be in the
         Service of the Company for so long as such individual (i) renders
         services on a periodic basis to the Company or one or more of its
         Parent or Subsidiary corporations as an Employee or (ii) serves as a
         non-employee member of the Board.

                           Subsidiary: A corporation shall be deemed to be a
         Subsidiary of the Company if it is a member of an unbroken chain of
         corporations beginning with the Company provided each corporation in
         such chain (other than the last corporation) owns, at the time of
         determination, stock possessing 50% or more of the total combined
         voting power of all classes of stock in one of the other corporations
         in such chain. In the event this option is a non-statutory option as
         specified in the Grant Notice, the term "Subsidiary" shall also include
         any partnership, joint venture or other business entity of which the
         Company owns, directly or indirectly through another subsidiary
         corporation, more than a fifty percent (50%) interest in voting power,
         capital or profits.

TERMS

                  1.       Grant of Option. Subject to and upon the terms and
conditions set forth in this Agreement, the Company hereby grants to Optionee,
as of the grant date (the "Grant Date") specified in the accompanying Notice of
Grant of Stock Option (the "Grant Notice"), a stock option to purchase up to
that number of shares of the Company's Common Stock (the "Optioned Shares") as
is specified in the Grant Notice. The Optioned Shares shall be purchasable from
time to time during the option term at the option price per share (the "Option
Price") specified in the Grant Notice.

                  2.       Option Term. This option shall have a maximum term of
five (5) years measured from the Grant Date and shall accordingly expire at the
close of business on the expiration date (the "Expiration Date") specified in
the Grant Notice, unless sooner terminated in accordance with Paragraph 5 or 7A
of this Agreement.

                                       2.
<PAGE>   23
                  3.       Transferability. This option shall not be
transferable or assignable by Optionee other than by will or by the laws of
descent and distribution. Accordingly, this option may be exercised, during
Optionee's lifetime, only by Optionee.

                  4.       Exercisability. This option shall become exercisable
for the Optioned Shares in one or more installments as is specified in the Grant
Notice. As the option becomes exercisable in one or more installments, it shall
remain so exercisable until the Expiration Date or sooner termination of the
option term under Paragraph 5 or Paragraph 7A of this Agreement.

                  5.       Termination of Service. In connection with the
Optionee's cessation of Service, the option term specified in Paragraph 2 shall
terminate (and this option shall cease to be exercisable) prior to the
ExpiratiOn Date in accordance with the following provisions:

                           (i)      Except as otherwise provided in
subparagraphs (ii) and (iii) below, should the Optionee's Service with the
Company terminate at any time during the option term, then the period for
exercising this option shall be reduced to a two (2) month period commencing
with the date of such termination of Service but in no event shall this option
be exercisable at any time after the Expiration Date. During such limited period
of exercisability, this option may not be exercised for more the number of
Optioned Shares (if any) for which the option is exercisable on the date of
Optionee's termination of Service.(1) Upon the expiration of such two (2) month
period or (if earlier) upon the Expiration Date, the option shall terminate and
cease to be outstanding.

                           (ii)     Should Optionee die while this option is
outstanding, then the personal representative of the Optionee's estate (or the
person or persons to whom the option is transferred pursuant to the Optionee's
will or in accordance with the laws of descent and distribution) shall have the
right to exercise this option for any or all of the Optioned Shares for which
this option is exercisable on the date of the Optionee's cessation of Service.
Such right shall lapse, and this option shall cease to be exercisable, upon the
earlier of (A) the

- -------------
         (1) In the event this option is an incentive stock option as specified
in the Grant Notice, the exercise of this option more than three (3) months
after the date of Optionee's cessation of Employee status for any reason (other
than death or permanent disability) will disqualify this option for favorable
tax treatment as further specified in Paragraph 17A.

                                       3.
<PAGE>   24
expiration of the six (6) month period measured from the date of Optionee's
cessation of Service or (B) the Expiration Date.

                           (iii)    Should the Optionee's Service be terminated
for any of the following reasons, then this option shall terminate and cease to
be exercisable immediately upon such termination of Service:

                                    (1)      Optionee's intentional misconduct
or continuing gross neglect of duties which materially and adversely affects the
business and operations of the Company or any Parent or Subsidiary corporation
employing Optionee;

                                    (2)      Optionee's unauthorized use or
disclosure (or attempt thereat) of confidential information or trade secrets of
the Company or its Parent or subsidiary corporations;

                                    (3)      Optionee's commission of an act
involving embezzlement, theft, fraud, falsification of records, destruction of
property or commission of a crime or other offense involving money or other
property of the Company or any Parent or subsidiary corporation employing
Optionee.

                  The reasons for termination of Optionee'S Service set forth in
this subparagraph (iii) are not intended to be, and are not inclusive of, all
acts or omissions which the Company may deem to constitute misconduct or other
grounds for terminating the Optionee's (or any other individual's) Service.

                  6.       Adjustment in Optioned Shares.

                  A.       In the event any change is made to the Common Stock
issuable under the Plan by reason of any stock dividend, stock split,
combination of shares, exchange of shares, or other change affecting the
outstanding Common stock as a class without receipt of consideration, the Plan
Administrator shall make appropriate adjustments to (a) the class and/or number
of securities subject to this option and (b) the Option Price payable per share
in order to reflect such change and thereby preclude a dilution or enlargement
of benefits hereunder. The adjustments so determined by the Plan Administrator
shall be final, binding and conclusive.

                  B.       In the event that (i) the Company is the surviving
entity in any Corporate Transaction (within the meaning of paragraph 7A) which
does not result in the termination of this option pursuant to the provisions of
Paragraph 7 or (ii) this option is to be assumed in connection with such
Corporate Transaction, then this option shall, immediately after such Corporate
Transaction, be appropriately adjusted to apply and

                                       4.
<PAGE>   25
pertain to the number and class of securities which would be issuable, in
consummation of such Corporate Transaction, to an actual holder of the same
number of shares of Common Stock as are subject to this option immediately prior
to such Corporate Transaction. Appropriate adjustments shall also be made to the
Option Price payable per share, provided the aggregate Option Price shall remain
the same.

                  7.       Corporate Transaction/Change in Control.

                  A.       Upon the occurrence of one or more of the following
transactions (a "Corporate Transaction"):

                           (i)      a merger or acquisition in which the Company
is not the surviving entity, except for a transaction the principal purpose of
which is to change the state of the Company's incorporation,

                           (ii)     the sale, transfer or other disposition of
all or substantially all of the assets of the Company to any entity other than a
Parent or Subsidiary of the Company, or,

                           (iii)    any reverse merger in which the Company is
the surviving entity but in which fifty percent (50%) or more of the Company's
outstanding voting stock is transferred to holders different from those who held
the stock immediately prior to such merger,

the exercisability of this option shall, to the extent it is not otherwise at
the time fully exercisable, be automatically accelerated so that such option
shall, immediately prior to the specified effective date for the Corporate
Transaction, become fully exercisable for all of the Optioned Shares and may be
exercised for all or any portion of such shares. No such acceleration of this
option, however, shall occur if and to the extent (i) the option is, in
connection with the Corporate Transaction, either to be assumed by the successor
corporation or parent thereof or be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation or parent
thereof or (ii) the option is to be replaced by a comparable cash incentive
program of the successor corporation based on the option spread (the excess of
the Fair Market Value of the shares of the Common Stock at the time subject to
the option over the Option Price payable for such shares) at the time of the
Corporate Transaction. The determination of option comparability under clause
(i) or (ii) shall be made by the Plan Administrator, and its determination shall
be final, binding and conclusive.

                  B.       This option, to the extent not previously exercised,
shall terminate upon the consummation of the Corporate

                                       5.
<PAGE>   26
Transaction and cease to be exercisable, unless it is expressly assumed by the
successor corporation or parent thereof.

                  C.       Upon the occurrence of one or more of the following
transactions (a "Change in Control"):

                           (i)      the acquisition by a person or group of
related persons, other than the Company or any person controlling, controlled by
or under common control with the Company, of beneficial ownership (as determined
pursuant to the provisions of Rule 13d-3 under the Securities Exchange Act of
1934, as amended) of securities of the Company representing thirty percent (30%)
or more of the combined voting power of the Company's then outstanding
securities pursuant to a transaction or series of related transactions which the
Board does not approve; or

                           (ii)     the first date within any period of thirty-
six (36) consecutive months or less on which there is effected any change in the
composition of the Board such that the majority of the Board (determined by
rounding up to the next whole number) ceases to be comprised of individuals who
either (I) have been members of the Board continuously since the beginning of
such period or (II) have been elected or nominated for election as Board members
during such period by at least a majority of the Board members described in
clause (I) who were still in office at the time such election or nomination was
approved by the Board;

the exercisability of this option (if outstanding at the time) shall be
automatically accelerated so that such option shall become exercisable,
immediately prior to the consummation or the Change in Control, for all of the
Optioned Shares and may be exercised for all or any portion of such shares at
any time thereafter until the expiration or sooner termination of the option
term.

                  D.       This Agreement shall not in any way affect the right
of the Company to adjust, reclassify, reorganize or otherwise make changes in
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

                  8.       Privilege of Stock Ownership. The holder of this

                  9.       Manner of Exercising Option.

                  A.       In order to exercise this option for one or more
Optioned Shares for which this option is at the time exercisable, Optionee (or
in the case of exercise after Optionee's death, the Optionee's executor,
administrator, heir or legatee, as the case may be) must take the following
actions:

                           (i)      Execute and deliver to the Secretary of the
Company a written notice of exercise (the "Exercise Notice") in substantially
the form of Exhibit I attached hereto.

                           (ii)     Pay the aggregate Option Price for the
purchased shares in one or more of the following alternative forms:

                                    (1)      full payment in cash or check made
payable to the Company's order; or

                                    (2)      full payment in shares of Common
Stock held by the Optionee for the requisite period necessary to avoid a charge
to the Company's reported earnings and valued at Fair Market Value on the
Exercise Date (as such term is defined below); or

                                    (3)      full payment in a combination of
shares of Common Stock held for the requisite period necessary to avoid a charge
to the Company's reported earnings and valued at Fair Market Value on the
Exercise Date and cash or check.

                           (iii)    Furnish to the Company appropriate
documentation that the person or persons exercising the option, if other than
Optionee, have the right to exercise this option.

                  B.       The Option Price may also be paid through a sale and
remittance procedure. Pursuant to such procedure, Optionee (I) shall provide
irrevocable written instructions to a designated brokerage firm to effect the
immediate sale of the purchased Optioned Shares and remit to the Company, out of
the sale proceeds available on the settlement date, sufficient funds to cover
the aggregate Option Price payable for such purchased shares plus all applicable
federal and state income and employment taxes required to be withheld by the
Company by reason of such purchase and (II) shall concurrently provide written
directives to the Company to deliver the certificates for the purchased Optioned
Shares directly to such brokerage firm in order to complete the sale
transaction.

                  C.       For purposes of this Agreement, the Exercise Date
shall be the first date on which the Exercise Notice shall have been delivered
to the Company. Except to the extent the sale and

                                       7.
<PAGE>   28
remittance procedure of Paragraph 9B is utilized, payment of the Option Price
shall immediately become due and shall accompany the Exercise Notice.

                  D.       As soon as practical after the Exercise Date, the
Company shall mail or deliver to Optionee (or to the other person or persons
exercising this option) a certificate or certificates representing the purchased
shares.

                  E.       In no event may this option be exercised for any
fractional shares.

                  10.      Compliance with Laws and Regulations.

                  A.       The exercise of this option and the issuance of
Optioned Shares upon such exercise shall be subject to compliance by the Company
and the Optionee with all applicable requirements of law relating thereto and
with all applicable regulations of any stock exchange on which shares of the
Company's Common Stock may be listed at the time of such exercise and issuance.

                  B.       In connection with the exercise of this option,
Optionee shall execute and deliver to the Company such representations in
writing as may be requested by the Company in order for it to comply with the
applicable requirements of federal and state securities laws.

                  11.      Successors and Assigns. Except to the extent
otherwise provided in Paragraph 3 or 7A, the provisions of this Agreement shall
inure to the benefit of, and be binding upon, the successors, administrators,
heirs, legal representatives and assigns of Optionee and the successors and
assigns of the Company.

                  12.      Liability of Company.

                  A.       If the Optioned Shares covered by this Agreement
exceed, as of the Grant Date, the number of shares of Common Stock which may
without shareholder approval be issued under the Plan, then this option shall be
void with respect to such excess shares unless shareholder approval of an
amendment sufficiently increasing the number of shares of Common Stock issuable
under the Plan is obtained.

                  B.       The inability of the Company to obtain approval from
any regulatory body having authority deemed by the Company to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Company of any liability with respect to the non-issuance or sale of
the Common Stock as to which such approval shall not have been obtained.

                                       8.
<PAGE>   29
The Company, however, shall use its best efforts to obtain all such approvals.

                  13.      No Employment or Service Contract. Nothing in this
Agreement or in the Plan shall confer upon the Optionee any right to continue in
the Service of the Company (or any Parent or Subsidiary employing or retaining
Optionee) for any period of time or otherwise interfere with or restrict in any
way the rights of the Company (or any Parent or Subsidiary employing or
retaining Optionee) or the Optionee, which rights are hereby expressly reserved
by each, to terminate the Optionee's Service at any time for any reason
whatsoever, with or without cause.

                  14.      Notices. Any notice required to be given or delivered
to the Company under the terms of this Agreement shall be in writing and
addressed to the Company in care of the Corporate Secretary at its principal
corporate offices. Any notice required to be given or delivered to Optionee
shall be in writing and addressed to Optionee at the address indicated below
Optionee's signature line on the Grant Notice. All notices shall be deemed to
have been given or delivered upon personal delivery or upon deposit in the U.S.
mail, postage prepaid and properly addressed to the party to be notified.

                  15.      Construction. This Agreement and the option evidenced
hereby are made and granted pursuant to the Plan and are in all respects limited
by and subject to the express terms and provisions of the Plan. All decisions of
the Plan Administrator with respect to any question or issue arising under the
Plan or this Agreement shall be conclusive and binding on all persons having an
interest in this option.

                  16.      Governing Law. The interpretation, performance, and
enforcement of this Agreement shall be governed by the laws of the State of
California without resort to that state's conflict-of-laws rules.

                  17.      Additional Terms Applicable to an Incentive Stock
Option. In the event this option is an incentive stock option as specified in
the Grant Notice, the following terms and conditions shall also apply to the
grant:

                  A.       This option shall cease to qualify for favorable tax
treatment as an incentive stock option under the federal tax laws if (and to the
extent) this option is exercised for one or more Optioned Shares: (i) more than
three (3) months after the date the Optionee ceases Employee status for any
reason other than death or permanent disability or (ii) more than one (1) year
after the date the Optionee ceases Employee status by reason of permanent
disability.

                                       9.
<PAGE>   30
                  For purposes of this Paragraph 17, Optionee shall be deeded to
be permanently disabled if Optionee is, by reason of any medically determinable
physical or mental impairment expected to result in death or to be of continuous
duration of twelve (12) consecutive months or more, unable to perform his/her
usual duties for the Company or Subsidiary retaining his/her services.

                  B.       Except in the event of a Corporate Transaction or
Change in Control under Paragraph 7, this option shall not become exercisable in
any calendar year during which it is outstanding if (and to the extent) the
aggregate fair market value (determined at the Grant Date) of the Common Stock
for which this option would otherwise first become exercisable in such calendar
year would, when added to the aggregate fair market value (determined as of the
respective date or dates of grant) of the Common Stock for which this option or
one or more other post-1986 incentive stock options granted to the Optionee
prior to the Grant Date (whether under the Plan or any other option plan of the
Company or any Parent or Subsidiary corporations) first become exercisable
during the same calendar year, exceed One Hundred Thousand Dollars ($100,000) in
the aggregate. To the extent the exercisability of this option is deferred by
reason of the foregoing limitation, the deferred portion will first become
exercisable in the first calendar year or years thereafter in which the One
Hundred Thousand Dollar ($100,000) limitation of this Paragraph 17B would not be
contravened.

                  C.       Should the exercisability of this option be
accelerated upon a Corporate Transaction or Change in Control in accordance with
Paragraph 7, then this option shall qualify for favorable tax treatment as an
incentive stock option under the federal tax laws only to the extent the
aggregate fair market value (determined at the Grant Date) of the Common Stock
for which this option first becomes exercisable in the calendar year in which
the Corporate Transaction or Change in Control occurs does not, when added to
the aggregate fair market value (determined as of the respective date or dates
of grant) of the Common Stock for which this option or one or more other
post-1986 incentive stock options granted to the Optionee prior to the Grant
Date (whether under the Plan or any other option plan of the Company or any
Parent or Subsidiary corporations) first become exercisable during the same
calendar year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate.

                  D.       To the extent this option should fail to qualify as
an incentive stock option under the federal tax laws, the Optionee will
recognize compensation income in connection with the acquisition of one or more
Optioned Shares hereunder, and the Optionee must make appropriate arrangements
for the satisfaction of all federal, state or local income tax withholding

                                       10.

requirements and federal social security employee tax requirements applicable to
such compensation income.

                  18.      Additional Terms Applicable to a Non-Statutory Stock
Option. In the event this option is a non-statutory stock option as specified in
the Grant Notice, Optionee hereby agrees to make appropriate arrangements with
the Company or Parent or Subsidiary employing Optionee for the satisfaction of
any federal, state or local income tax withholding requirements and federal
social security employee tax requirements applicable to the exercise of this
option.

                            INDEMNIFICATION AGREEMENT

THIS AGREEMENT, made and entered into the 14th day of May, 1990 between Giga-

                                WITNESSETH THAT:

         WHEREAS, Officer of the Corporation, performs a valuable service in
such capacity of Corporation; and

insurance ("D & O Insurance"), covering certain liabilities which may be
incurred by its directors and officers in the performance as officers and
directors of Corporation; and

         WHEREAS, as a result of recent developments affecting the terms, scope
and availability of D & O Insurance there exists general uncertainty as to the
extent of protection afforded officers and directors by such D & O Insurance and
by statutory and by-law indemnification provisions; and

         WHEREAS, in order to induce Officer to continue to serve as an officer
of Corporation, Corporation has determined and agreed to enter into this
contract with Officer;

                   Corporation for any of the following:

                   (i)      except to the extent the aggregate of losses to be
                            indemnified thereunder exceeds the sum of such 
                            losses for which the Officer is indemnified pursuant
                            to Section 1 hereof or pursuant to any D & O

                            violation of law;

                   (iii)    on account of any suit in which judgment is rendered

                            from the purchase or sale by Officer of securities
                            of Corporation pursuant to the provisions of section
                            16(b) of the Securities Exchange Act of 1934 and
                            amendments thereto or similar provisions of any
                            federal, state or local statutory law;

                   (iv)     on account of Officer's acts or omissions that

<PAGE>   3
                    (vii)   on account of any action, suit or proceeding
                            commenced by the Officer against the
                            Corporation or against any officer, director
                            or shareholder of the Corporation unless
                            authorized in the specific case by action of
                            the Board of Directors;

              (b)   In addition to those limitations set forth above in
                    paragraph (a) of this Section 3, no indemnity
                    pursuant to Section 2 hereof in an action by or in
                    the right of Corporation shall be paid by Corporation
                    for any of the following:

                    (i)     on account of acts or omissions that Officer
                            believes to be contrary to the best interests of
                            the Corporation or its shareholders or that involve
                            the absence of good faith on the part of Officer;

                    (ii)    with respect to any transaction from which Officer
                            derived an improper personal benefit;

                    (iii)   on account of acts or omissions that show a
                            reckless disregard for Officer's duty to the
                            Corporation or its shareholders in circumstances in
                            which Officer was aware, or should have been aware,
                            in the ordinary course of performing an officer's
                            duties, of a risk of serious injury to Corporation
                            or its shareholders;

                    (iv)    on account of acts or omissions that constitute an
                            unexcused pattern of inattention that amounts to an
                            abdication of Officer's duty to the Corporation or
                            its shareholders;

                    (v)     to the extent prohibited by Section 310 of the 
                            California Corporations Code, "Contracts In Which
                            Officer Has Material Financial Interest";

                    (vi)    to the extent prohibited by Section 316 of the 
                            California Corporations Code, "Corporate Actions
                            Subjecting Officers To Joint And Several Liability"
                            (for prohibited distributions, loans and 
                            guarantees);

                    (vii)   in respect to any claim, issue or matter as to 
                            which Officer shall have been adjudged to be liable
                            to Corporation in the performance of Officer's duty
                            to Corporation and its shareholders, unless and 
                            only to the extent that the court in which such
                            proceeding is or was pending shall determine upon
                            application that, in view of all the circumstances
                            of the case, Officer is fairly and reasonably
                            entitled to indemnity for

  
                                       3.
<PAGE>   4
                            expenses and then only to the extent that the court
                            shall determine;

                    (viii)  of amounts paid in settling or otherwise disposing 
                            of a pending action without court approval; or

                    (ix)    of expenses incurred in defending a pending action
                            which is settled or otherwise disposed of without 
                            court approval.

         4.   CONTRIBUTION.  If the indemnification provided in 1 and 2 is 
              unavailable and may not be paid to Officer for any reason other
              than those set forth in Section 3 (excluding subsections
              3(b)(viii) and (ix), then in respect of any threatened pending
              or completed action, suit or proceeding in which Corporation is
              jointly liable with Officer (or would be if joined in such
              action, suit or proceeding), Corporation shall contribute to the
              amount of expenses (including attorneys' fees), judgments, fines
              and amounts paid in settlement actually and reasonably incurred
              and paid or payable by Officer in such proportion as is
              appropriate to reflect (i) the relative benefits received by
              Corporation on the one hand and Officer on the other hand from
              the transaction from which such action, suit or proceeding
              arose, and (ii) the relative fault of Corporation on the one
              hand and of Officer on the other in connection with the events
              which resulted in such expenses, judgments, fines or settlement
              amounts, as well as any other relevant equitable considerations.
              The relative fault of Corporation on the one hand and the
              Officer on the other shall be determined by reference to, among
              other things, the parties' relative intent, knowledge, access to
              information and opportunity to correct or prevent the
              circumstances resulting in such expenses, judgments, fines or
              settlement amounts. Corporation agrees that it would not be just
              and equitable if contribution pursuant to this Section 4 were
              determined by pro rata allocation or any other method of
              allocation which does not take account of the foregoing
              equitable consideration.

         5.   CONTINUATION OF OBLIGATIONS.  All agreements and obligations of 
              Corporation contained herein shall continue during the period
              Officer is a director, officer, employee or agent of Corporation
              (or is or was serving at the request of Corporation as a
              director, officer, employee or agent of another corporation,
              partnership, joint venture, trust or other enterprise) and shall
              continue hereafter so long as Officer shall be subject to any
              possible claim or threatened, pending or completed action, suit
              or proceeding, whether civil, criminal or investigative by
              reason of the fact that Officer was an officer of Corporation or
              serving in any other capacity referred to herein.

         6.   NOTIFICATION AND DEFENSE OF CLAIM.  Promptly after receipt by 
              Officer of notice of the commencement of any action, suit or
              proceeding, Officer will, if a claim


                                       4.
<PAGE>   5



              in respect thereof is to be made against Corporation under this
              Agreement, notify Corporation of the commencement thereof; but
              the omission so to notify Corporation will not relieve it from
              any liability which it may have to Officer otherwise than under
              this Agreement. With respect to any such action, suit or
              proceeding as to which officer notifies Corporation of the
              commencement thereof;

              (a)  Corporation will be entitled to participate therein at its 
                   own expense;

              (b)  except as otherwise provided below, to the extent that it may
                   wish, Corporation jointly with any other indemnifying party
                   similarly notified will be entitled to assume the defense
                   thereof, with counsel satisfactory to Officer. After notice
                   from Corporation to Officer of its election so as to assume
                   the defense thereof, Corporation will not be liable to
                   Officer under this Agreement for any legal or other expenses
                   subsequently incurred by Officer in connection with the
                   defense thereof other than reasonable costs of investigation
                   or as otherwise provided below. Officer shall have the right
                   to employ its counsel in such action, suit or proceeding but
                   the fees and expenses of such counsel incurred after notice
                   from Corporation of its assumption of the defense thereof
                   shall be at the expense of Officer unless (i) the employment
                   of counsel by Officer has been authorized by Corporation,
                   (ii) Officer shall have reasonably concluded that there may
                   be a conflict of interest between Corporation and Officer in
                   the conduct of the defense of such action, in each of which
                   cases the fees and expenses of counsel shall be at the
                   expense of Corporation. Corporation shall not be entitled to
                   assume the defense of any action, suit or proceeding brought
                   by or on behalf of Corporation or as to which Officer shall
                   have made the conclusion provided for in (ii) above; and

              (c)  Corporation shall not be liable to indemnify Officer under 
                   this Agreement for any amounts paid in settlement of any
                   action or claim effected without its written consent.
                   Corporation shall not settle any action or claim in any
                   manner which would impose any penalty or limitation on
                   Officer without Officer's written consent. Neither
                   Corporation nor Officer will unreasonably withhold its
                   consent to any proposed settlement.

         7.   ADVANCEMENT AND PAYMENT OF EXPENSES.

              (a)  In the event that Officer employs his own counsel pursuant to
                   Section 6(b)(i) through (iii) above, Corporation shall
                   advance to Officer, prior to any final disposition of any
                   threatened or pending


                                       5.

                   action, suit or proceeding, whether civil, criminal,
                   administrative or investigative, any and all reasonable
                   expenses (including legal fees and expenses) incurred in
                   investigating or defending any such action, suit or
                   proceeding within ten (10) days after receiving copies of
                   invoices presented to Officer for such expenses; and

              (b)  Officer agrees that Officer will reimburse Corporation for
                   all reasonable expenses paid by Corporation in defending any
                   civil or criminal action, suit or proceeding against Officer
                   in the event and only to the extent it shall be ultimately
                   determined by a final judicial decision (from which there is
                   no right of appeal) that Officer is not entitled, under
                   applicable law, the by-laws, this Agreement or otherwise, to
                   be indemnified by Corporation for such expenses.

         8.   ENFORCEMENT.

              (a)  Corporation expressly confirms and agrees that it has
                   entered into this Agreement and assumed the obligations
                   imposed on Corporation hereby in order to induce Officer to
                   continue as an Officer of Corporation, and acknowledges that
                   Officer is relying upon this Agreement in continuing in such
                   capacity.

              (b)  In the event Officer is required to bring any action to
                   enforce rights or to collect monies due under this Agreement
                   and is successful in such action, Corporation shall
                   reimburse Officer for all of Officer's reasonable fees and
                   expenses in bringing and pursuing such action.

         9.   SEPARABILITY.  Each of the provisions of this Agreement is a
              separate and distinct agreement and independent or the others,
              so that if any provision hereof shall be held to be valid or
              unenforceable for any reason, such invalidity or
              unenforceability shall not affect the validity or enforceability
              of the other provisions hereof.

         10.  GOVERNING LAW.  This Agreement shall be interpreted and enforced
              in accordance with the laws of the State of California.

         11.  BINDING EFFECT.  This Agreement shall be binding upon Officer and
              upon Corporation, its successors and assigns, and shall inure to
              the benefit of Officer, his heirs, personal representatives and
              assigns and to the benefit of Corporation, its successors and
              assigns.

         12.  AMENDMENT AND TERMINATION.  No amendment, modification, 
              termination or cancellation of this Agreement shall be effective
              unless in writing signed by both parties hereto.

         THIS LEASE, dated as of December 6, 1993, is made by and between
CalFront Associates, a California corporation (herein called "Landlord") and
Giga-tronics Incorporated, a California corporation (herein called "Tenant").

1.       Definitions.

         1.1      Base Monthly Rent: The amount specified on Schedule A which
Tenant is to pay each month pursuant to Paragraph 4.1 and subject to adjustment
as provided on Schedule A.

         1.2      Commencement Date: The date on which the term of this Lease is
to begin which shall be the date specified in Schedule A, subject to adjustment
pursuant to Paragraphs 3.2 and 3.3.

         1.3      Building: The building indicated on Schedule A.

         1.4      Premises: That area located within the Building as indicated
on Schedule A.

         1.5      Net Rentable Area of Premises: That area comprising the
Premises which is hereby stipulated for all purposes to contain the square
footage indicated on Schedule A, as such square footage may be recalculated
following the initial tenant improvements based on ANSI Publication Z65.1 (1980)
(BOMA standard). The initial determination of Net Rentable Area shall be made by
Landlord's architect following contruction of the initial tenant improvements in
each portion of the Premises. Within thirty (30) days after Tenant takes
possession of each portion of the Premises, Tenant may, at its expense, have its
architect recalculate the Net Rentable Area of the applicable portion of the
Premises. In the event the actual Net Rentable Area of the Demised Premises
differs from the initial calculation of Landlord's architect, the Base Monthly
Rent and all additional charges based on Net Rentable Area shall be
proportionately adjusted as of the Commencement Date to reflect Tenant's actual
Net Rentable Area. Tenant shall pay such rent and additional charges based on
the initial calculation of Landlord's architect pending final determination of
the actual Net Rentable Area. The parties shall execute an instrument
acknowledging the actual Net Rentable Area once it has been finally determined.

         1.6      Tenant's Percentage Share: The percentage indicated on
Schedule A. Such Tenant's Percentage Share is derived by dividing the Net
Rentable Area of the Premises by the total rentable area of the Building.
Landlord shall initially calculate Tenant's Percentage Share based on the
initial calculation of Net Rentable Area provided by Landlord in accordance with
Paragraph 1.5 above, subject to later adjustment in the event of a
redetermination of Net Rentable Area of the Premises. Landlord reserves the
right, in the future, to readjust Tenant's Percentage Share to reflect the
addition or removal of improvements to the total space on which expenses passed
through to Tenant will be calculated. Any adjustments will be made on a
reasonable basis and so as not to prejudice Tenant.

         1.7      The following terms shall have the meanings specified where
indicated:

         a.       Additional Rent: Paragraph 4.2

         b.       Alterations: Paragraph 6.3

         2.2      Common Areas.

                  (a)      As used herein, "Common Areas" shall mean all areas

the project. Landlord may from time to time change the size, location, nature
and use of any of the Common Areas, including converting Common Areas into
leasable areas and increasing or decreasing common area land, floor space and/or
facilities; provided, however, that any such change in the Common Areas shall
not unreasonably interfere with Tenant's use and enjoyment of the Premises or
materially decrease the quality or level of Common Area services and facilities.

                  (b)      Tenant, its employees, agents, customers and business
invitees shall have the nonexclusive right (in common with all others to whom
Landlord has granted or may hereafter grant such rights) to use the Common Areas
for the purposes intended, subject to such reasonable rules and regulations
relating to such use as Landlord may from time to time establish. Landlord may

thereto, or to prevent the acquisition of public rights in such areas, and
reasonable may do such other acts in and to the Common Areas as in its
reasonable judgment it deems appropriate, so long as reasonable access to the
Premises remains available. Tenant shall not at any time unreasonably interfere
with the rights of Landlord, other tenants, or of any other person entitled to
use the Common Areas, to use any part thereof.

3.       Term.

         3.1      Term. This Lease shall be for the term specified on Schedule
A, commencing on the Commencement Date specified on such Schedule A, or, if
later, the date upon which the Initial Improvements to be installed by Landlord

terminated pursuant to any provision hereof. The Initial Improvements shall be
deemed to be substantially complete upon the earliest to occur of the following:
(a) the date by which all improvements to be constructed by Landlord have been
completed, except for punch list items which do not prevent Tenant from using
the Premises for their intended use, and the relevant local authority has issued
a certificate of temporary occupancy for the Premises or the equivalent
(provided, however, that the issuance of such local authority approval shall be
deemed to have occurred if denied solely by reason of the failure Tenant's Work
to satisfy local authority requirements), or (b) the date Tenant opens for
business in the Premises. The parties shall, after the Lease Commencement Date
has occurred, execute an instrument specifying the actual Lease Commencement
Date.

         3.2      Delay in Possession. Notwithstanding said Commencement Date,
if for any reason Landlord cannot deliver possession of the Premises to Tenant
on said date, Landlord shall not be subject to any liability therefor, nor shall
such failure affect the validity of this Lease or the obligations of Tenant
hereunder, but, in such case, Tenant shall not be obligated to pay rent until
the initial improvements are substantially complete in accordance with Paragraph
3.1 above, and the Expiration Date shall be automatically extended; provided,
however, that if Landlord shall not have delivered possession of the Premises
within 90 days from said Commencement Date, Tenant may, at Tenant's option, by
notice in writing to Landlord within ten (10) days thereafter, cancel this
Lease, in which event the parties shall be discharged from all obligations
hereunder; provided that such 90-day period shall be subject to extension for
any delays (i) caused by Tenant requests for changes in Landlord's construction,
if any, or due to fault or neglect of Tenant or Tenant's agents or contractors,
or (ii) due to acts of God, strikes, fires, weather, casualty, war, acts of
governmental bodies, inability to obtain labor or materials or other causes
beyond Landlord's reasonable control.

         3.3      Early Possession. Subject to any early occupancy for
completion of Tenant's Work as specified in Paragraphs 4.1 and 6.1 of Exhibit C,
if Tenant occupies the Premises prior to said Commencement Date, such occupancy
shall be subject to all provisions hereof, such occupancy shall not advance the
Expiration Date, and Tenant shall pay rent for such period at the initial Base
Monthly Rent set forth in Schedule A for the period following any free rent
period.

4.       Rent.

         4.1      Base Rent. Tenant shall pay to Landlord, as Base Monthly Rent
for the Premises, the amount specified on Schedule A. Rent shall be payable in
advance, on or before the first day of each month of the term hereof. Rent for
any period during the term hereof which is for less than one month shall be a
pro rata portion of the monthly installment. Rent shall be payable in lawful
money of the United States to Landlord without deduction, offset, prior notice
or demand at the address stated herein or to such other persons or at such other
places as Landlord may designate in writing.

         4.2      Additional Rent. As rent for the Premises, in addition to the
Base Monthly Rent, Tenant shall pay to Landlord, in the amounts and at the times
provided, all of the other charges and payments provided for in this Lease
("Additional Rent"), such as (but not limited to) Operating Expenses over the
Base Year (including any insurance premiums payable by Tenant, taxes payable by
Tenant, jointly metered utility charges, common area costs), late charges, and
interest ("Additional Rent"). Unless otherwise specified herein, all payments of
Additional Rent shall be payable in full on the date that the next installment
of Base Monthly Rent is payable.

         4.3      Operating Expenses.

                  (a)      Tenant shall pay to Landlord as Additional Rent
Tenant's Percentage Share (as specified on Schedule A) of all Operating Expenses
as hereinafter defined during each calendar year or part thereof during the term
of this Lease over the amount of Operating Expenses paid during the Base Year
specified on Schedule A, in accordance with the following provisions. Subject to
the exclusions in (e) below, "Operating Expenses" shall mean the total cost and
expenses paid or incurred by Landlord in the exercise of its discretion in
connection with the management, operation, maintenance and repair of the
Building, including an allocable proportion of the shared cost and expenses of
Common Areas and other costs of the project as allocated to the Building by
Landlord in its reasonable good faith determination. Such Operating Expenses
shall include, without limitation, (i) the cost of air conditioning,
electricity, heating, mechanical, ventilating, elevator systems and all other
utilities (to the extent not separately charged or metered to Tenant) and the
cost of supplies and equipment and maintenance and service contracts in
connection therewith (to the extent the heating, ventilating, and air
conditioning systems in the Premises are not maintained by Tenant at Tenant's
sole cost); (ii) all costs, charges and fees associated with all water and sewer
service supplied but not separately metered to Tenant and all costs of any other
utility not separately assessed to Tenant; (iii) the cost of watchmen, guards
and security personnel and services; (iv) the cost of repairs (including,
without limitation, roof repairs and 

                                       9.
<PAGE>   10
maintenance and repair of the structural components of the Building), general
maintenance, plumbing service, janitorial and cleaning service, and fire
protection systems; (v) the cost of fire, extended coverage, boiler, sprinkler,
public liability, property damage, rent, earthquake, and other insurance paid by
Landlord; (vi) wages, salaries and other labor costs, including employee
benefits; (vii) fees, charges and other costs, including management fees,
consulting fees, legal fees and accounting fees, of all independent contractors
engaged by Landlord or reasonably charged by Landlord if Landlord performs
management services in connection with the Building or project; (viii) license,
permit and inspection fees; (ix) supplies, materials, tools and equipment and
the cost of supplying, replacing and cleaning employee uniforms; (x) the fair
market rental value of Landlord's or the property manager's offices in any
building used in the management of the Building or Common Areas; (xi) all costs
and expenses of contesting by appropriate legal proceedings any matter
concerning operating or managing the Building or Common Areas; (xii)
depreciation on all personal property, fixtures and equipment used in the
management, operation, maintenance and repair of the Building or Common Areas;
(xiii) all costs associated with the operation, management, maintenance and
repair of the Common Areas, including landscaping and gardening, signs,
maintenance, repairs, resurfacing, repaving, painting, refinishing, lighting,
cleaning, storm drainage and sanitary sewer systems, refuse removal, snow, ice
and ash removal; (xiv) the cost of any capital improvements made to the Building
or project after completion of its construction as a labor-saving device or to
effect other economies in the operation or maintenance of the Building or
project, or made to the Building or project after the date of this Lease that
are required under any governmental law or regulation that was not applicable to
the Building or project at the time that permits for the construction thereof
were obtained, such cost to be amortized over the useful life of the
improvement, provided, however, that in the case of a cost-saving capital
improvement the amortization of the cost of such improvement shall be at a rate
that shall not exceed the actual savings realized by such measure; (xv) the cost
of all Real Property Tax paid by Landlord pursuant to Paragraph 9; (xvi) costs
incurred to test, survey, clean up, contain, abate, remove or otherwise remedy
Hazardous Substances from the Building or project except to the extent caused by
Landlord's negligence or intentional acts or the proven negligence or
intentional acts of any other tenant in the Building; and (xvii) any other
expense of any other kind whatsoever reasonably incurred in managing, operating,
maintaining and repairing the Building or project. Expenses shall be adjusted to
reflect a ninety-five percent (95%) occupancy of the Building. The determination
of Operating Expenses and their allocation shall be in accordance with generally
accepted accounting principles applied on a consistent basis. If the Common
Areas contain more than one building at any time during the Lease term, then the
term "Operating Expenses" shall mean and include all of the Operating Expenses
allocable to the Premises and a proportionate share (based on the square footage
of gross rentable area in the Premises as a percentage of the total of square
footage of gross rentable area of the buildings on the Common Areas at the time
in question) of all Operating Expenses which are related to such buildings in
general and are not allocated to any one building on the Common Areas. The
specific examples of Operating Expenses stated in this Paragraph are in no way
intended to and shall not limit the costs comprising Operating Expenses, nor
shall such examples be deemed to obligate Landlord to incur such costs or to
provide such services or to take such actions except as Landlord may be
expressly required in other portions of this Lease, or except as Landlord, in
its sole discretion, may elect.

                  (b)      Tenant shall pay to Landlord as Additional Rent
during each calendar year or part thereof during the term of this Lease
one-twelfth (1/12th) of Tenant's Percentage Share of the increase in Operating
Expenses over the Base Year for each such calendar year or partial calendar year
on or before the first day of each calendar month, in advance, in an amount
estimated by Landlord and billed by Landlord to Tenant; provided that Landlord
shall have the right initially to determine reasonable monthly estimates and to
revise such estimates from time to time but not more often than twice per
calendar year. With reasonable promptness, but no later than 90 days after the
expiration of each calendar year, Landlord shall furnish Tenant with a statement
(herein called "Landlord's Expense Statement"), setting forth in reasonable
detail the Operating Expenses for such calendar year and Tenant's Percentage
Share, if any, of the increase in such Operating Expenses. If the actual
increase in Operating Expenses for the Building for such calendar year exceed
the estimated increase in Operating Expenses paid by Tenant for such calendar
year, Tenant shall pay to Landlord the difference between the amount paid by
Tenant and the actual increase in 

                                      10.
<PAGE>   11
Operating Expenses within 30 days after the receipt of Landlord's Expense
Statement, and if the total amount paid by Tenant for any such calendar year
shall exceed the actual increase in Operating Expenses for such calendar year,
such excess shall be credited against the next installment of rent, or at the
end of the Term, reimbursed within 30 days of expiration or early termination of
the Lease.

                  (c)      If for any calendar year any tenant of the Building
(including Tenant) is separately metered for any utility, the utility for which
such tenant is separately metered shall not be included in Operating Expenses
for the computation of the Additional Rent to be paid by such tenant for such
calendar year under this Paragraph. In such event, for purposes of computing the
portion of each utility that is separately metered to any tenant to be paid by
the tenants that are not separately metered, Tenant's Percentage Share shall be
the percentage figure obtained by dividing the rentable area of the premises of
each tenant that is not separately metered by the total rentable area of all the
tenants that are not separately metered. In the event any utility is separately
metered for only a portion of any calendar year, such charges shall be prorated
on a daily basis based upon a thirty (30) day month in accordance with the
foregoing formula. Such computations shall be shown on Landlord's Expense
Statement for the applicable calendar year.

                  (d)      If the expiration date fixed for this Lease shall
occur on a date other than the end of a calendar year, Tenant's Percentage Share
of increased Operating Expenses for the calendar year in which the expiration
date falls shall be prorated on an annual basis; provided, however, Landlord
may, pending the determination of the amount of increased Operating Expenses for
such partial calendar year, furnish Tenant with statements of estimated excess
Operating Expenses and Tenant's Percentage Share thereof for such partial
calendar year. Within 30 days after receipt of such estimated statement, Tenant
shall remit to Landlord, as Additional Rent, the amount of Tenant's Percentage
Share of such increase in Operating Expenses. After such Operating Expenses have
been finally determined and Landlord's Expense Statement furnished to Tenant
pursuant to this Paragraph, if there has been an underpayment of Tenant's
Percentage Share of increased Operating Expenses, Tenant shall remit the amount
of such underpayment to Landlord within 30 days of receipt of such statements
and, if there has been an overpayment, Landlord shall remit the amount of any
such overpayment to Tenant within 30 days of the issuance of such statement.

                  (e)      Notwithstanding anything in this Lease to the
contrary, Operating Expenses shall not include the following: (i) legal fees,
brokerage commissions, advertising costs, or other related expenses incurred in
connection with the leasing of the Building or project; (ii) any capital
improvements or alterations, except as expressly provided in (a) above;
provided, however, that structural repairs or improvements costing less than
$25,000 shall not be deemed capital, and that the costs of replacement or repair
of the roof membrane amortized over its useful life may be included in Operating
Expenses; (iii) depreciation or amortization of the Building; (iv) damage and
repairs to the extent covered by the proceeds of any insurance policy carried
by, or required to be carried by, Landlord in connection with the Building,
project or Common Areas; (v) executive salaries; (vi) salaries of service
personnel to the extent that the service personnel perform services not solely
in connection with the management, operation, repair or maintenance of the
Building, project or Common Areas; (vii) Landlord's general overhead expenses
not related to the Building or project; (viii) payments of principal or interest
on any mortgage or other encumbrance; (ix) legal fees, accountants' fees and
other expenses incurred in connection with disputes with Tenant, tenants or
other occupants or associated with the enforcement of any lease or defense of
Landlord's title to or interest in the Building or project to the extent such
defense does not benefit tenants of the Building; (x) costs (including permit,
license and inspection fees) incurred in renovating or otherwise improving,
decorating, painting or altering space for other tenants or other occupants or
vacant space in the Building or project; (xi) interest, penalties or other costs
arising out of Landlord's failure to make timely payment of its obligations;
(xii) the cost of any service provided to Tenant or other occupants of the
Building or project and not to Tenant for which Landlord is to be reimbursed
separately; (xiii) overhead and profit paid to subsidiaries or affiliates of
Landlord for management or other services for the project or Building or for
supplies or other materials to the extent that the costs of the services,
supplies or materials exceed the competitive costs of the services, supplies or
materials if they were not provided by a subsidiary or an affiliate; (xiv)
damage 

                                      11.
<PAGE>   12
and repairs necessitated by the negligence or wilful misconduct of Landlord or
Landlord's employees, contractors or agents; (xv) costs incurred due to a proven
violation by any other tenant in the Building of the terms and conditions of any
lease; (xvi) costs of operating and maintaining any portion of the Building or
Common Areas which is used for parking and for which parking fees are charged;
(xvii) property management fees to the extent they exceed customary and
reasonable charges in the San Ramon/Pleasanton local area; (xviii) costs
incurred in advertising and promotional activities for the Building (including
gifts and promotional services to tenants or other parties); (xix) cost of
capital improvements otherwise permitted to be passed through to Tenant
hereunder in excess of the costs amortized over the useful life of the capital
improvement (for which purposes repair or improvement costs shall be capitalized
if over $25,000 in any one instance and otherwise expensed); and (xx) rent for
space within the Building or other locations other than as expressly permitted
in 4.3(a)(x).

                  (f)      Tenant shall have the right, at Tenant's expense, at
all reasonable times upon ten days' prior written notice within one year
following receipt of Landlord's statements (or, in the case of retroactive
billings, within 12 months following receipt of Landlord's invoice), to audit
Landlord's books and records relating to the Operating Expenses of the Building
for the previous calendar year at the office where Landlord keeps such
documents. If it is determined following such audit that payment adjustments are
required, Landlord or Tenant, as the case may be, shall make the required
payment within 30 days thereafter. In the event such audit reveals that
Landlord's Expense Statement overstated actual Operating Expenses by more than
five percent (5%) for any particular year, Landlord shall reimburse Tenant for
the reasonable cost of such audit.

                  (g)      Landlord shall increase the Operating Expenses paid
or incurred by Landlord during the Base Year to the extent there is a component
of Operating Expenses incurred after the Base Year which (i) was not paid or
incurred in the Base Year; (ii) is not the result of any requirement imposed by
a governmental agency; and (iii) is not approved by Tenant. The amount of the
increase in the Operating Expenses paid or incurred by Landlord during the Base
Year as a result of an additional component of Operating Expenses shall be the
amount which Landlord and Tenant reasonably determine would have been paid or
incurred by Landlord in the Base Year in connection with the additional
component. If increase shall be the amount of the Operating Expense paid in the
first year the additional component is paid (i.e., a year after the Base Year),
reduced by a percentage equal to the percentage increase in the Consumer Price
Index between the Base Year and the first year the component is paid.

5.       Use.

         5.1      Use.

                  The Premises shall be used and occupied only for the permitted
use stated on Schedule A and for related purposes.

         5.2      Compliance with Law and Restrictions.

                  (a)      Tenant shall comply promptly with all applicable
statutes, ordinances, rules, regulations, orders, easements, covenants and
restrictions of record, and requirements in effect during the term hereof
applicable to the space within the Premises (or resulting from tenant
improvements), regulating the use by Tenant of the Premises, including the
Covenants, Conditions and Restrictions specified on Schedule A, a copy of which
is attached as Exhibit F. The costs of Tenant's compliance shall be borne solely
by Tenant except to the extent the costs (i) relate to any portion of the
Building other than the space leased by Tenant or (ii) result from the failure
of the Premises (other than the tenant improvements constructed by Tenant) to
comply with the applicable statutes, etc., as of the Commencement Date.
Notwithstanding the foregoing, Landlord shall at Landlord's expense be
responsible for complying with the Americans with Disabilities Act as applicable
to the Building and Premises on the Commencement Date. Tenant shall not use nor
permit the use of the Premises in any manner that will tend to create waste or a
nuisance or result in any increase in any insurance premiums payable on
insurance carried on the Premises, or, if there shall be more than one tenant in
the Building containing the Premises, shall tend to disturb such other 

                                      12.
<PAGE>   13
tenants. Tenant shall not cause, maintain or permit any outside storage on or
about the Premises. Tenant shall not conduct nor permit to be conducted any
auction on the Premises without Landlord's prior written consent.

         5.3      Condition of Premises.

                  (a)      Landlord shall deliver the Premises to Tenant clean
and free of debris on the Lease Commencement Date (unless Tenant is already in
possession). Except as otherwise provided in this Lease, Tenant shall be deemed
to have accepted the Premises in their "as is" condition existing as of the
Lease Commencement Date or the date Tenant takes possession of the Premises,
whichever is earlier, subject to all applicable zoning, municipal, county and
state laws, ordinances and regulations governing the use of the Premises, and
any covenants or restrictions of record, and accepts this Lease subject thereto
and to all matters disclosed thereby and by any exhibits attached hereto. Tenant
acknowledges that neither Landlord nor any real estate broker or other agent of
Landlord has made any representation or warranty as to the present or future
suitability of the Premises for the conduct of Tenant's business.

                  (b)      Landlord shall have no obligation to construct or
install in the Premises any improvements, fixtures or equipment whatsoever,
except to the extent otherwise provided in Exhibit C attached hereto, if any. By
taking possession of the Premises, Tenant is deemed to have accepted Initial
Improvements to be constructed by Landlord (if any) as being completed in
accordance with the plans and specifications for such improvements, subject only
to completion of items on Landlord's and Tenant's punch list, and except for
patent defects which Tenant identified to Landlord within 30 days of the
Commencement Date and latent defects not reasonably discoverable by Tenant
within such 30-day period.

         5.4      Hazardous Substances. Except in compliance with all government
approvals, applicable Laws and regulations pertaining to Hazardous Materials (as
defined below), and in accordance with the additional provisions of this
Paragraph 5.4, Tenant shall not cause or permit the presence, use, handling,
generation, emission, release, discharge, storage or disposal of any Hazardous
Materials on, under, in or about the Premises; and shall not cause or permit the
transportation of any Hazardous Materials to or from the Premises. Tenant shall
indemnify, protect, defend, and hold harmless Landlord from and against all
liability, and foreseeable consequential damages, penalties, expenses and costs
of any required or necessary remediation, repair, removal, cleanup or
detoxification, of the Premises and surrounding properties, and from and against
the preparation of any cleanup, remediation, closure or other required plans,
whether such action is required or necessary prior to or following the
termination of this Lease, to the full extent that the same is attributable to
the presence, use, handling, generation, emission, release, discharge, storage
or disposal of Hazardous Materials by Tenant, its agents, employees, or
contractors. Neither the written consent by Landlord to the handling, use,
presence, generation, emission, release, discharge, storage, or disposal of
Hazardous Materials nor the strict compliance by Tenant with all Laws and
government approvals pertaining to Hazardous Materials shall excuse Tenant from
Tenant's obligations of indemnification pursuant to this Paragraph. Tenant shall
at all times notify Landlord of any Hazardous Materials present, used,
generated, handled, emitted, released, discharged, stored or disposed of on or
from the Premises. Notwithstanding the foregoing, notice shall not be required
for Hazardous Materials present on the Premises in reasonable quantities which
are commonly used in business offices including, but not limited to, cleaning
materials, correcting fluids, and toner used in photocopy machines, provided
such Hazardous Materials are used and disposed of in accordance with law. Tenant
shall also observe any reasonable, additional requirements imposed by Landlord
from time to time in the presence, use, handling, generation, emission, release,
discharge, storage or disposal of Hazardous Materials, and shall institute
operating procedures designed to handle Hazardous Materials consistent with
prudent industry practice. Landlord shall have the right to inspect the Premises
on 24- hours' prior notice for compliance with the provisions of this Paragraph.
If Landlord in its reasonable judgment decides that the manner or extent of
Tenant's activities involving Hazardous Materials so require or that Tenant is
violating its obligations under this Paragraph in its handling of Hazardous
Materials, Landlord may hire an independent expert to develop a Hazardous
Materials program for Tenant and monitor 

                                      13.
<PAGE>   14
Tenant's compliance therewith. Tenant shall reimburse Landlord for the
reasonable cost of such independent consultant promptly upon demand.

         The term "Hazardous Materials" shall mean any toxic substance,
hazardous substance, hazardous material, or hazardous waste, pollutant or
contaminant which is or becomes regulated by any local governmental authority,
the State of California, or the United States government, including, but not
limited to, any material or substance which is (i) defined as a "hazardous
waste", "extremely hazardous waste" or "restricted hazardous waste" under
Sections 25115, 25117 or 25122.7, or listed pursuant to Section 25140 of the
California Health and Safety Code, Division 20, Chapter 6.5 (Hazardous Waste
Control Law), (ii) defined as a "hazardous substance" under Section 25316 of the
California Health and Safety Code, Division 20, Chapter 6.8
(Carpenter-Presley-Tanner Hazardous Substance Account Act), (iii) listed as a
chemical known to cause cancer or reproductive toxicity pursuant to Section
25249.8 of the California Health and Safety Code, Division 20, Chapter 6.6 (Safe
Drinking Water and Toxic Enforcement Act), (iv) designated as a "hazardous
substance" pursuant to Section 6380 of the California Labor Code, Division 5,
Chapter 2.5 (Hazardous Substances Information and Training Act); (v) defined as
a "hazardous waste" pursuant to Section 1004 of the Resource Conservation and
Recovery Act, 42 U.S.C. Section 6901 et seq. (42 U.S.C. Section 6903), (vi)
defined as a "hazardous substance" pursuant to Section 101 of the Comprehensive
Environmental Response, Compensation, and Liability Act, 42 U.S.C. Section 9601
et seq. (42 U.S.C. Section 9601), or (vii) defined as a "hazardous material,"
"Hazardous substance," or "hazardous waste" under Section 25501 of the
California Health and Safety Code, Division 20, Chapter 6.95 (Hazardous
Materials Release Response Plans and Inventory), (viii) defined as a "hazardous
substance" under Section 25281 of the California Health and Safety Code,
Division 20, Chapter 6.7 (Underground Storage of Hazardous Substances), (ix)
listed under Article 9 or defined as hazardous or extremely hazardous pursuant
to Article 11 of Title 22 of the California Administrative Code, Division 4,
Chapter 20.

6.       Maintenance, Repairs and Alterations.

         6.1      Landlord's Obligations.

         (a)      Subject to the provisions of Paragraphs 5, 6.2 and 8 and,
except for damage caused by any negligent or intentional act or omission of
Tenant, Tenant's agents, employees or invitees, in which event, Tenant shall
repair the damage, Landlord shall keep in good order, condition and repair (i)
the gross structural components of the Premises and the Building, namely the
foundations, subflooring, exterior walls, bearing walls, and structural roof
components; (ii) the Common Areas, including landscaping, driveways, parking
lots, fences and signs located on the Building site and all sidewalks and
parkways adjacent to the Building, (iii) Building systems and utility
installations to the outlets, and (iv) the roof membrane; the expenses of which
shall be recovered from Tenant for Tenant's Percentage Share as specified on
Schedule A to the extent permitted by Paragraph 4.3. In addition, Landlord shall
maintain the heating, ventilation and air conditioning systems serving the
Premises, the expenses of which shall be included in Operating Expenses to the
extent they are for portions of the heating, ventilation and air conditioning
system up to and including the central heating, ventilation and air conditioning
system equipment within Landlord's utility room, and the expenses of which shall
be directly reimbursable by Tenant to the extent they are for portions of the
heating, ventilation and air conditioning system from such utility room and
within the Premises (which would otherwise be Tenant's obligation to maintain
and repair). Landlord shall have no obligation to make repairs under this
Paragraph 6.1 until a reasonable time after receipt of written notice of the
need for such repairs. There shall be no abatement of rent or liability of
Landlord on account of any injury or interference with Tenant's business with
respect to any improvements, alterations or repairs made by Landlord to any part
of the Building or the Premises. Tenant expressly waives the benefit of any
statute now or hereafter in effect which would otherwise afford Tenant the right
to make repairs at Landlord's expense or to terminate this Lease because of
Landlord's failure to keep the Premises in good order, condition and repair.
Notwithstanding the foregoing, if Landlord fails to perform repairs and
maintenance after reasonable notice from Tenant (but in no event less than 30
days), Tenant can repair and invoice Landlord for the actual reasonable cost
therefor for payment within 30 days.


                                      14.
<PAGE>   15
             (b) Landlord shall, prior to the Commencement Date hereof,
construct certain Initial Improvements to the Premises in accordance with
Exhibit C, if any.

         6.2 Tenant's Obligations.

             (a) Subject to the provisions of Paragraphs 5, 6.1 and 8, Tenant,
at Tenant's expense, shall keep in good order, condition and repair the Premises
and every part thereof (whether or not the damaged portion of the Premises or
the means of repairing the same are reasonably or readily accessible to Tenant)
including, without limiting the generality of the foregoing, any and all
telephone and telecommunications wiring and equipment, fixtures, interior walls,
and interior surface of exterior walls, ceilings, windows, doors, plate glass,
showcases, skylights and entrances located within the Premises, and the
electrical, plumbing, lighting, heating and air conditioning systems (unless
Landlord has elected to keep and maintain the heating, ventilation and air
conditioning systems pursuant to Paragraph 6.1).

             (b) If Tenant fails to perform Tenant's obligations under this
Paragraph 6.2 or under any other Paragraph of this Lease, Landlord may, at
Landlord's option, enter upon the Premises after ten (10) days' prior written
notice to Tenant (except in the case of emergency, in which case no notice shall
be required), to perform such obligations on Tenant's behalf and put the
Premises in good order, condition and repair, and the cost thereof together with
interest thereon from the date of Landlord's expenditure at the rate specified
in Paragraph 18 shall be due and payable as Additional Rent to Landlord within
30 days following Landlord's invoice to Tenant.

             (c) On the Expiration Date of the term hereof, or on any earlier
termination, Tenant shall surrender the Premises to Landlord in the same
condition as received, clean and free of debris, ordinary wear and tear
excepted. Any damage or deterioration of the Premises shall not be deemed
ordinary wear and tear if the same could have been avoided by good maintenance
practices by Tenant. Tenant shall repair any damage to the Premises, occasioned
by the installation or removal of its trade fixtures, furnishings and equipment.
Notwithstanding anything to the contrary stated in this Lease, Tenant shall
leave the air lines, power panels, electrical distribution systems, lighting
fixtures, space heaters, heating and air conditioning systems, window coverings,
wall coverings, carpets, panelling, ceilings, and plumbing on the Premises in
good order and operating condition.

         6.3 Alterations.

             (a) Tenant shall not, without Landlord's prior written consent
(which shall not be unreasonably withheld or delayed), make any Alterations or
Utility Installations or repairs in, on or about the Premises or attach any
fixtures or equipment thereto, except for interior decorative and nonstructural
Alterations exceeding $20,000 in any instance during the term of this Lease. As
used in this Paragraph 6.3, the term "Alterations" shall mean any alterations,
additions, improvements, construction, maintenance, repair, replacement,
installation, removal or decoration undertaken by Tenant in connection with the
Premises. The term "Utility Installations" shall mean carpeting, window and wall
coverings, air lines, power panels, electrical distribution systems, lighting
fixtures, space heaters, air conditioning, plumbing, and telephone and
telecommunications wiring and equipment and any other system. Landlord may
require that Tenant remove any or all of said Alterations or Utility
Installations installed after Tenant's initial occupancy, at the expiration of
the term, and restore the Premises to their prior condition, provided that
Landlord notifies Tenant at the time Landlord consents to their installation
that it reserves the right to require their removal. Should Tenant make any
Alterations or Utility Installations without the prior approval of Landlord,
Landlord may require that Tenant remove any and all of the same.

             (b) Any Alterations or Utility Installations in, on or about the
Premises that Tenant shall desire to make and which requires the consent of the
Landlord shall be presented to Landlord in written form, with complete plans and
specifications. If Landlord shall give its consent, the consent shall be deemed

governmental agencies, the furnishing of a copy thereof to 

                                      15.
<PAGE>   16
Landlord prior to the commencement of the work and the compliance by Tenant with
all conditions of said permit in a prompt and expeditious manner. The contractor
or person selected by Tenant to make such Alterations or Utility Installations
must be approved in writing by Landlord (such approval not to be unreasonably
withheld, conditioned, or delayed) prior to commencement of any work, and such
contractor or person shall, at all times, be subject to Landlord's control while
in the Building and shall comply with Landlord's Rules and Regulations for
Tenant Contractors, the current version of which is attached hereto as Exhibit
E. Tenant shall also require its contractor to maintain insurance in amounts and
in such form as Landlord may reasonably require and naming Landlord as an
additional insured. Any Alterations or Utility Installations shall be completed
in substantial accordance with the plans and specifications approved by
Landlord, shall be carried out in a good, workmanlike and prompt manner, shall
be of good and sufficient quality and materials, shall comply with all
applicable laws and shall be subject to reasonable supervision by Landlord or
its authorized representatives. Without Landlord's prior written consent, which
shall not be unreasonably withheld, Tenant shall not use any portion of the
Common Areas in connection with the making of any Alterations or Utility
Installations. Should any Alterations or Utility Installations on the Premises
by Tenant interfere with the harmonious labor relations in existence in the
Building, Tenant shall take all reasonable steps to halt such interference,
including, if necessary, cessation of the work.

             (c) Tenant shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Tenant at or for use in
the Premises, which claims are or may be secured by any mechanics' or
materialmen's lien against the Premises or any interest therein. Tenant shall
give Landlord not less than fifteen (15) days' notice prior to the commencement
of any work in the Premises, and Landlord shall have the right to post notices
of non-responsibility in or on the Premises as provided by law. If Tenant shall,
in good faith, contest the validity of any such lien, claim or demand, then
Tenant shall, at its sole expense, defend itself and Landlord against the same
and shall pay and satisfy any adverse judgment that may be rendered thereon
before the enforcement thereof against the Landlord or the Premises, upon the
condition that if Landlord shall require, Tenant shall furnish to Landlord a
surety bond satisfactory to Landlord in an amount equal to such contested lien,
claim or demand indemnifying Tenant against liability for the same and holding
the Premises free from the effect of such lien or claim. In addition, Landlord
may require Tenant to pay Landlord's attorneys' fees and costs in participating
in such action if Landlord shall decide it is to its best interest to do so.

             (d) Unless Landlord requires their removal, as set forth in
Paragraph 6.3(a), all Alterations and Utility Installations (whether or not they
constitute trade fixtures of Tenant) which may be made on the Premises,
including but not limited to the floor coverings, panelings, doors, drapes,
built-ins, moldings, soundproofing and lighting and telephone or communications
systems, conduit, wiring and outlets, shall become the property of Landlord and
remain upon and be surrendered with the Premises at the expiration of the term.
Notwithstanding the provisions of this Paragraph 6.3(d), Tenant's machinery and
equipment, other than that which is affixed to the Premises so that it cannot be
removed without material damage to the Premises, shall remain the property of
Tenant and may be removed by Tenant subject to the provisions of Paragraph
6.2(a).

             (e) Tenant shall provide Landlord with as-built plans and
specifications for any Alterations or Utility Installations.

7.       Indemnity; Insurance.

         7.1 Indemnity.

             (a) Tenant shall indemnify and hold harmless Landlord from and
against any and all claims to the extent arising from Tenant's use or occupancy
of the Premises, or from the conduct of Tenant's business or from any activity,
work or things done, permitted or suffered by Tenant in, on or about the
Premises other than claims to the extent arising primarily by reason of
negligence or wilful acts of third parties or of Landlord, its agent, employees
or contractors, and shall further indemnify and hold harmless Landlord from and
against any and all claims to the extent arising from any breach or default in
the performance 

                                      16.
<PAGE>   17
of any obligation on Tenant's part to be performed under the terms of this
Lease, or arising from the negligent or intentional acts or omissions of the
Tenant, or any of Tenant's agents, contractors, or employees, and from and
against all costs, attorneys' fees, expenses and liabilities incurred in the
defense of any such claim or any action or proceeding brought thereon; and in
the case of any action or proceeding brought against Landlord by reason of any
such claim, Tenant upon notice from Landlord shall defend the same at Tenant's
expense by counsel satisfactory to Landlord. Tenant, as a material part of the
consideration to Landlord, hereby assumes all risk of injury to Tenant's
business, loss of income, damage to property or injury to persons, in, on or
about the Premises arising from any cause and Tenant hereby waives all claims in
respect thereof against Landlord.

             (b) Landlord shall defend, indemnify, hold and save Tenant harmless
from and against any and all loss, costs, claims, liability or damage (including
reasonable attorneys' fees or court costs) in connection with Landlord's
ownership and management of the Premises, Building and project other than claims
arising primarily by reason of the wilful misconduct or negligence of third
parties or of Tenant, or Tenant's officers, contractors, agents or employees.

         7.2 Tenant's Insurance. During the term of this Lease, Tenant shall at
Tenant's expense, obtain and keep in force the following policies of insurance:

             (a) Comprehensive General Liability Insurance protecting Tenant
against any liability for injury or death to any person or persons or damage to
property arising out of Tenant's exclusive use, occupancy or maintenance of the
Premises. The limits of such liability insurance shall not be less than Two
Million Dollars ($2,000,000.00) combined single limit per occurrence, such limit
to be increased upon Landlord's request whenever Landlord reasonably determines
that such an increase is required adequately to protect Landlord from the
matters insured against.

             (b) All-Risk Property Insurance covering loss or damage to Tenant's
fixtures, equipment or tenant improvements. All insurance required under this
Paragraph 7.2 shall be written on an occurrence basis and be (i) issued by such
good and responsible companies qualified to do and doing business in the state
where the Premises are located and with a Best's rating of B+XI or better, and
(ii) name Landlord as a named additional insured by an additional insured
endorsement. Tenant shall deliver to Landlord certificates evidencing the
existence and amounts of insurance required above and, if requested by Landlord,
copies of the insurance policies. No such policy shall be cancellable or subject
to reduction of coverage except upon thirty (30) days' written notice to
Landlord. Tenant shall, within thirty (30) days of expiration of such policies,
furnish Landlord with certificates of renewal or "binders" therefor.

         7.3 Landlord's Insurance. Landlord shall, at Tenant's expense, obtain
and keep in force during the term of this Lease the following insurance:

             (a) Comprehensive General Liability Insurance covering bodily
injury and property damage liabilities arising out of the Landlord's ownership,
use, occupancy or maintenance of the Premises and all areas appurtenant thereto
in an amount not less than Two Million Dollars ($2,000,000.00) combined single
limit per occurrence.

             (b) Property Insurance covering loss or damage to the Building, but
not Tenant's fixtures, equipment or tenant improvements in an amount not less
than 80% of the full replacement value thereof, as the same may exist from time
to time, providing protection against all perils included within the
classification "all risk," as such term is used in the insurance industry,
including vandalism and malicious mischief, but excluding flood or earthquake
coverage unless required by a lender having a lien on the Premises. In addition,
Landlord may obtain and keep in force during the term of this Lease, a policy of
rental value insurance covering a period of one year, with loss payable to
Landlord, which insurance shall also cover all real estate taxes and insurance
costs for said period.

                                      17.
<PAGE>   18
             (c) Such other insurance (including flood or earthquake coverage)
as Landlord reasonably deems necessary and prudent.

         7.4 Payment of Premium. Tenant shall pay to Landlord during the term
hereof, as Additional Rent, Tenant's Percentage Share of the increase over the
Base Year of premiums for the insurance required under Paragraph 7.3, in
accordance with Paragraph 4.3.

         7.5 Waiver of Subrogation. Landlord and Tenant each hereby release and
relieve the other, and waive their entire right of recovery against the other
for loss or damage arising out of or incident to risks insured against under all
policies of fire and extended coverage, public liability, workers' compensation
and other insurance now or hereafter existing during the term hereof and
covering any portion of the Premises or any operations therein, regardless of
cause, including negligence of the other party, its agents, employees and
contractors. Landlord and Tenant shall, upon obtaining the policies of insurance
required hereunder, advise each insurance carrier that the foregoing mutual
waiver of subrogation is contained herein, and each party covenants that no
insurer shall hold any right of subrogation against such other party.

<PAGE>   19

to cancel and terminate this Lease, Tenant shall have the right within ten (10)
days after the receipt of such notice to give written notice to Landlord of
Tenant's intention to repair such damage at Tenant's expense, without
reimbursement from Landlord, in which event, this Lease shall continue in full
force and effect, and Tenant shall proceed to make such repair as soon as
reasonably possible. If Tenant does not give such notice within such ten (10)
day period, this Lease shall be cancelled and terminated as of the date of the
occurrence of such damage.

this Lease there is material damage, whether or not an Insured Loss, which falls
within the classification of Premises Partial Damage, either party may, at its
option, cancel and terminate this Lease as of the date of occurrence of such
damage by giving written notice to the other party of its election to do so
within thirty (30) days after the date of occurrence of such damage.

             (b) Notwithstanding Paragraph 8.5(a), in the event that Tenant has
an option to extend or renew this Lease, and the time within which said option

is to be exercised at all, no later than twenty (20) days after the occurrence
of an Insured Loss falling within the classification of Premises Partial Damage
during the last six (6) months of the term of this Lease. If Tenant duly
exercises such option during said twenty (20) day period, Landlord shall, at
Landlord's expense, repair such damage as soon as reasonably possible, and this
Lease shall continue in full force and effect. If Tenant fails to exercise such
option during said twenty (20) day period, then Landlord may, at Landlord's
option, terminate and cancel this Lease as of the expiration of said twenty (20)
day period by giving written notice to Tenant of Landlord's election to do so
within ten (10) days after the expiration of said twenty (20) day period,
notwithstanding any term or provision in the grant of option to contrary.

         8.6 Abatement of Rent; Tenant's Remedies.

             (a) In the event of damage described in Paragraphs 8.2 or 8.3, and
Landlord or Tenant repairs or restores the Premises pursuant to the provisions
of this Paragraph 8, the rent payable hereunder for the period during which such
damage, repair or restoration continues shall be abated in proportion to the
area of the Premises unusable for the period from occurrence of the damage to
the date of the restoration. Except for abatement of rent, if any, Tenant shall
have no claim against Landlord for any damage suffered by reason of such damage,
destruction, repair or restoration; provided, however, that nothing shall
restrict Tenant's ability to pursue recovery from Tenant's insurer(s).

             (b) If Landlord shall be obligated to repair or restore the
Premises under the provisions of this Paragraph 8 and such restoration and
repair is not reasonably estimated to be capable of completion within 180 days
after the damage or destruction or if Landlord shall not commence preparations
for such repair or restoration within ninety (90) days after such obligations
shall accrue, Tenant may, at Tenant's option, cancel and terminate this Lease by
giving Landlord written notice of Tenant's election to do so at any time within
20 

                                      19.
<PAGE>   20
days after Landlord notifies Tenant that (i) the restoration period will exceed
180 days or (ii) the end of the 90-day period, provided Landlord has not
completed the repair or restoration before Tenant gives Landlord such notice. In
such event, this Lease shall terminate as of the date of such notice.

         8.7 Termination - Advance Payments. Upon termination of this Lease
pursuant to this Paragraph 8, an equitable adjustment shall be made concerning

         9.1 Payment of Tax. Landlord shall pay the Real Property Tax, as
defined in Paragraph 9.3, applicable to the Building and the land upon which it
is located; provided, however, that Tenant shall pay, as an item of Operating
Expenses, Tenant's Percentage Share of the increase in such Real Property Tax
over that in the Base Year, in the manner provided for Operating Expenses in
Paragraph 4.3, or, at Landlord's election, within thirty (30) days after receipt
of Landlord's written statement setting forth the amount of such pro rata share.
If the term of this Lease shall not expire concurrently with the expiration of
the tax fiscal year, Tenant's liability for taxes for the last partial lease
year shall be prorated on an annual basis.

         9.2 Additional Improvements. Notwithstanding Paragraph 9.1 hereof,
Tenant shall pay to Landlord within thirty (30) days of receipt of Landlord's
demand therefor the entirety of any increase in Real Property Tax if assessed
solely by reason of additional improvements placed upon the Premises by Tenant
or at Tenant's request.

         9.3 Definition of Real Property Tax. As used herein, the term "Real
Property Tax" shall include (to the extent any of the following are not paid by
Tenant pursuant to Paragraphs 9.2 and 9.5) any form of real estate tax or
assessment, general, special, ordinary or extraordinary, any service payments in
lieu of taxes, any personal property taxes, sales and/or use taxes, employee
taxes, and any excises, license fee, commercial rental tax, improvement bond or
bonds, transit charges, housing fund assessments or other housing charges,
parking facilities assessments or other parking charges, environmental
surcharges, levy or tax, foreseen or unforeseen (other than inheritance,
personal income or estate taxes) imposed on the Premises and/or Common Areas by
any authority having the direct or indirect power to tax, including any city,
state or federal government, or any school, agricultural, sanitary, fire,
street, drainage or other improvement district thereof, as against any legal or
equitable interest of Landlord in the Premises or in the real property of which
the Premises are a part, as against Landlord's right to rent or other income
therefrom, and as against Landlord's business of leasing the Premises. The term
"Real Property Tax" shall also include any tax, fee, levy, assessment or charge
(i) in substitution of, partially or totally, any tax, fee, levy, assessment or
charge hereinabove included within the definition of Real Property Tax, or (ii)
the nature of which was hereinbefore included within the definition of Real
Property Tax, or (iii) all other governmental, quasi-governmental or special
district impositions of any kind, present or future, whether or not customary or
within the contemplation of the parties hereto and regardless of whether
resulting from increased rate and/or valuation, or (iv) which is imposed as a
result of a transfer, either partial or total, of Landlord's interest in the
Premises and/or Common Areas or which is added to a tax or charge hereinbefore

tenant improvements in the Building; (iii) gross receipts taxes; nor (iv) any

                                      20.
<PAGE>   21
increase in Real Property Tax due to a reassessment of the property following a
change of ownership by CalFront Associates during the initial five years of the
Term, provided, however, that at its option, in lieu of excluding such sums from
the definition of Real Property Tax, Landlord may pay Tenant the net present
value of such sum (discounted at the federal discount rate) at the time of the
reassessment.

         9.4  Joint Assessment. If the Building and the Common Areas are not
separately assessed, Tenant's liability shall be an equitable proportion of the
Real Property Tax for all of the land and improvements included within the tax
parcel(s) assessed, such proportion to be determined by Landlord from the
respective valuations assigned in the assessor's worksheets or such other
information as may be reasonably available. Landlord's reasonable determination
thereof, in good faith, shall be conclusive.

         9.5  Personal Property Taxes.

              (a) Tenant shall pay, prior to delinquency, all taxes assessed
against and levied upon trade fixtures, furnishings, equipment and all other
personal property of Tenant contained in the Premises. When possible, Tenant
shall cause said trade fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of
Landlord.

              (b) If any of Tenant's said personal property shall be assessed
with Tenant's real property, Tenant shall pay Landlord the taxes attributable to
Tenant within 30 days after receipt of a written statement setting forth the
taxes applicable to Tenant's property.

10.      Utilities and Services.

         (a)  Tenant shall pay for all gas, heat, light, power, telephone and
other utilities and services supplied to the Premises, together with any taxes
thereon. If such services are not separately metered to Tenant, Tenant shall pay
a reasonable proportion of all charges jointly metered with other premises; such
amount to be determined in good faith by Landlord. Tenant shall also contract
separately for and pay the cost of all janitorial services to the Premises.

         (b)  Any heating, ventilation and air conditioning service provided by
Landlord to Tenant during other than ordinary business hours shall be furnished
on 24 hours' prior written notice of Tenant and at Tenant's sole cost, which
shall be an amount equal to Landlord's actual cost of supplying HVAC systems to
the HVAC systems zone of which the Premises form a part (consisting of (i)
Landlord's actual out-of-pocket third party costs; (ii) reasonable repair and
maintenance costs; and (iii) reasonable charge for depreciation) not to exceed
$35 per hour in the first year of the Term.

11.      Assignment and Subletting.

         11.1 Landlord's Consent Required. Tenant shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Tenant's interest in this Lease or in the Premises,
without Landlord's prior written consent, which shall not be unreasonably
withheld or delayed. Any attempted assignment, transfer, mortgage, encumbrance
or subletting without such consent shall be voidable and shall, at Landlord's
option, constitute a breach of this Lease that entitles Landlord to terminate
this Lease. Tenant agrees that the instrument by which any assignment or
subletting consented to by Landlord is accomplished shall be in a form
satisfactory to Landlord and shall expressly provide that the assignee or
subtenant will perform and observe all the agreements, covenants, conditions and
provisions to be performed and observed by Tenant under this Lease as and when
performance and observance is due, and that Landlord will have the right to
enforce such agreements, covenants, conditions and provisions directly against
such assignee or subtenant. Any subtenant shall, by reason of entering into a
sublease under this Lease, be deemed, for the benefit of Landlord, to have
assumed and agreed to conform and comply with each and every obligation of
Tenant hereunder, other than such obligations as 

                                      21.
<PAGE>   22
are contrary to provisions contained in a sublease to which Landlord has
expressly consented in writing.

         11.2 Tenant Affiliate. Notwithstanding the provisions of Paragraph 11.1
hereof, Tenant may assign or sublet the Premises, or any portion thereof,
without Landlord's consent, to any corporation which wholly controls, is
controlled by or is under common control with Tenant, or to any corporation
resulting from the merger or consolidation with Tenant, or to any person or
entity which acquires all the assets of Tenant as a going concern of the
business that is being conducted on the Premises, provided that said assignee
assumes, in full, the obligations of Tenant under this Lease. Any such
assignment shall not, in any way, affect or limit the liability of Tenant under
the terms of this Lease.

         11.3 No Release of Tenant. Regardless of Landlord's consent, no
subletting or assignment shall release Tenant of Tenant's obligation or alter
the primary liability of Tenant to pay the rent and to perform all other
obligations to be performed by Tenant hereunder, whether accruing before or
after such subletting or assignment, except as provided in Paragraph 11.6 below.
The acceptance of rent by Landlord from any other person shall not be deemed to
be a waiver by Landlord of any provision hereof. Consent to one assignment or
subletting shall not be deemed consent to any subsequent assignment or
subletting. In the event of default by any assignee of Tenant or any successor
of Tenant in the performance of any of the terms hereof, Landlord may proceed
directly against Tenant without the necessity of exhausting remedies against
said assignee. Landlord may consent to subsequent assignments or subletting of
this Lease or amendments or modifications to this Lease with assignees of Tenant
without notifying Tenant or any successor of Tenant, and without obtaining its
or their consent thereto, and such action shall not relieve Tenant of liability
under this Lease.

         11.4 Notice of Assignment or Subletting. Before entering into any
assignment of this Lease or into a sublease of all or a part of the Premises for
which Landlord's consent is required hereunder, Tenant shall give written notice
to Landlord (a) identifying the intended assignee or subtenant by name and
address, (b) describing the nature of the proposed business to be carried on in
the Premises, (c) specifying the terms of the intended assignment or sublease,
and (d) providing such financial and other business information as Landlord may
reasonably request concerning the proposed assignee or subtenant (including,
without limitation, a bank reference and financial statements for the two most
recently completed fiscal years). Landlord shall respond to Tenant's request for
consent within ten business days of submission of all requested information.
Failure of Landlord to respond within the ten business day period shall be
deemed a consent by Landlord to the request.

         11.5 Condition to Landlord's Consent. As a condition to Landlord's
consent to any assignment or subletting, Landlord shall be entitled to receive,
in the case of a subletting, 50% of the rent (however denominated and paid)
payable by the subtenant to Tenant in excess of that payable by Tenant to
Landlord hereunder and, in the case of an assignment, 50% of the consideration
given, directly or indirectly, by the assignee to Tenant in connection with such
assignment, after Tenant has first recovered its unamortized costs of tenant
improvements in the Premises (amortized over the remainder of the then-current
Term) and any direct costs incurred by it in such assignment or sublease such as
brokerage commissions and tenant improvements made for the sublessee or
assignee. For purposes of this Paragraph, the term "rent" shall mean all
consideration paid or given, directly or indirectly, for the use of the Premises
or any portion thereof. The term "consideration" shall mean and include money,
services, property or any other thing of value such as payment of costs,
cancellation of indebtedness, discounts, rebates and the like. The rent or other
consideration which is to be passed through to Landlord by Tenant pursuant to
this Paragraph shall be paid to Landlord promptly upon receipt by Tenant and
shall be paid in cash, irrespective of the form in which received by Tenant from
any subtenant or assignee. If any rent or other consideration received by Tenant
from a subtenant or assignee is in a form other than cash, Tenant shall pay to
Landlord in cash the fair value of such consideration.

         11.6 Landlord's Expenses. In the event Tenant shall assign or sublet
the Premises or request the consent of Landlord to any assignment or subletting,
then Tenant shall pay 

                                      22.
<PAGE>   23
Landlord's reasonable costs and direct expenses incurred in connection
therewith, not to exceed $1,000, including, without limitation, attorneys' fees,
and Landlord may condition its consent on the payment thereof.

12.      Defaults; Remedies.

         12.1 Defaults. The occurrence of any one or more of the following
events shall constitute a material default and breach of this Lease by Tenant:

              (a) the abandonment of the Premises by Tenant; providing that the
Premises shall not be deemed abandoned if vacated in such a manner that the
Premises are properly secured and Landlord's insurance premiums do not increase;

              (b) the failure by Tenant to make payment of Base Monthly Rent,
Additional Rent, or any other payment required to be made by Tenant hereunder,
as and when due, where such failure shall continue for a period of ten days
after written notice thereof from Landlord to Tenant;

              (c) the failure by Tenant to observe or perform any of the
covenants, conditions or provisions of this Lease to be observed or performed by
Tenant, other than described in Subparagraph (b) or (f), where such failure
shall continue for a period of 30 days after written notice thereof from
Landlord to Tenant; provided, however, that if the nature of Tenant's default is
such that more than 30 days are reasonably required for its cure, then Tenant
shall not be deemed to be in default if Tenant commences such cure within said
30-day period and thereafter diligently prosecutes such cure to completion;

              (d) (i) the making by Tenant of any general arrangement or
assignment for the benefit of creditors; (ii) Tenant's becoming a "debtor" as
defined in 11 U.S.C. Section 101 or any successor statute thereto (unless, in
the case of a petition filed against Tenant, the same is dismissed within 60
days); (iii) the appointment of a trustee or receiver to take possession of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within 30
days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this lease, where such seizure is not discharged within 30 days. In
the event that any provision of this Paragraph 12.1(d) is contrary to any
applicable law, such provision shall be of no force or effect.

              (e) The discovery by Landlord that any financial statement given
to Landlord by Tenant, any assignee of Tenant, any subtenant of Tenant, any
successor in interest of Tenant or any guarantor of Tenant's obligations
hereunder, and any of them, was materially false, if Tenant (or its assignee or
subtenant) knows that such financial information is false.

              (f) An assignment, subletting or other transfer or attempted
transfer in violation of Paragraph 11.

         12.2 Remedies. In the event of any such material default or breach by
Tenant, Landlord may at any time thereafter, with or without notice or demand
and without limiting Landlord in the exercise of any right or remedy which
Landlord may have by reason of such default or breach:

              (a) Terminate Tenant's right to possession of the Premises by any
lawful means, in which case, this Lease shall terminate, and Tenant shall
immediately surrender possession of the Premises to Landlord. In such event,
Landlord shall be entitled to recover from Tenant all damages incurred by
Landlord by reason of Tenant's default, including, but not limited to, (i) the
cost of recovering possession of the Premises; (ii) expenses of reletting,
including necessary renovation and alteration of the Premises, reasonable
attorneys' fees, and any real estate commission actually paid; (iii) the worth
at the time of the award by the court having jurisdiction thereof of the unpaid
rent earned at the time of termination of Tenant's right to possession of the
Premises; (iv) the worth at the time of the award of the amount by which the
unpaid rent that would have been earned after the date of termination of
Tenant's 

                                      23.
<PAGE>   24
right to possession until the time of award exceeds the amount of the loss of
rent for the same period that Tenant proves could be reasonably avoided; (v) the
worth at the time of award of the amount by which the unpaid rent for the
balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Tenant proves could be reasonably avoided;
and (vi) that portion of any leasing commission paid by Landlord applicable to
the unexpired term of the Lease.

              (b) Maintain Tenant's right to possession in which case this Lease
shall continue in effect whether or not Tenant shall have abandoned the
Premises. In such event, Landlord shall be entitled to enforce all of Landlord's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

              (c) Pursue any other remedy now or hereafter available to Landlord
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Tenant under the terms of this Lease shall bear interest from the date due at
the rate specified in Paragraph 18.

         12.3 Default by Landlord. Landlord shall not be in default unless
Landlord fails to perform obligations required of Landlord within a reasonable
time but, in no event, later than thirty (30) days after written notice by
Tenant to Landlord, specifying where Landlord has failed to perform such
obligation; provided, however, that if the nature of Landlord's obligation is
such that more than thirty (30) days are required for performance, then Landlord
shall not be in default if Landlord commences performance within such thirty
(30) day period and thereafter diligently prosecutes the same to completion.

         12.4 Late Charges. Tenant hereby acknowledges that late payment by
Tenant to Landlord of rent and other sums due hereunder will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed on
Landlord by the terms of any mortgage or deed of trust covering the Premises.
Accordingly, if any installment of rent or any other sum due from Tenant shall
not be received by Landlord or Landlord's designee within ten days after such
amount shall be due, Landlord shall deliver a notice to Tenant of the
delinquency and Tenant shall pay to Landlord a late charge equal to five percent
(5%) of such overdue amount; provided, however, that for the first late payment
under this Lease no late charge shall be payable unless the payment is not made
within 10 days following written notice that such payment is late, and
thereafter that no such late charge shall be payable for the first late payment
in any 12-month period. The parties hereby agree that such late charge
represents a fair and reasonable estimate of the costs Landlord will incur by
reason of late payment by Tenant. Acceptance of such late charge by Landlord
shall, in no event, constitute a waiver of Tenant's default with respect to such
overdue amount, nor prevent Landlord from exercising any of the other rights and
remedies granted hereunder. Any overdue rent and other payments due from Tenant
under this Lease and not paid when due shall bear interest at the rate specified
in Paragraph 18.

         12.5 Landlord's Right to Cure Defaults. All agreements, covenants,
conditions and provisions to be performed or observed by Tenant under this Lease
shall be at its sole cost and expense and without any abatement of rent. If
Tenant shall fail to pay any sum of money, other than rent, required to be paid
by it hereunder or shall fail to perform any other act on its part to be
performed hereunder, Landlord may, but shall not be obligated to do so, and
without having or releasing Tenant from any obligations of Tenant, make any such
payment or perform any such other act on Tenant's part to be made or performed
as provided in this Lease. All sums so paid by Landlord and all reasonably
necessary incidental costs shall be deemed Additional Rent hereunder and shall
be payable to Landlord on demand, together with interest thereon at the rate
specified in Paragraph 18 per annum at the time of expenditure by Landlord from
the date of expenditure to the date of repayment by Tenant, and Landlord shall
have (in addition to any other right or remedy of Landlord) the same rights and
remedies in the event of the nonpayment thereof by Tenant as in the case of
default by Tenant in the payment of rent.

                                      24.
<PAGE>   25
13.      Condemnation. If the Premises or any portion thereof or of the Building
are taken under the power of eminent domain, or sold under the threat of the
exercise of said power (all of which are herein called "condemnation"), this
Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs. If more than
twenty-five percent (25%) of the floor area of the Premises is taken, or if so
much of the Common Areas of the Building is taken as would render the Premises
untenantable, as reasonably determined by Landlord, Tenant may, at Tenant's
option, to be exercised in writing only within ten (10) days after Landlord
shall have given Tenant written notice of such taking (or in the absence of such
notice, within ten (10) days after the condemning authority shall have taken
possession), terminate this Lease as of the date the condemning authority takes
such possession. If Tenant does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the rent shall be reduced in the proportion
that the floor area of the Premises taken bears to the total floor area of the
Premises. No reduction of rent shall occur if only Common Areas, areas not
included in the Premises, or areas not within the Building are taken. Any award
for the taking of all or any part of the Premises under the power of eminent
domain or any payment made under threat of the exercise of such power shall be
the property of Landlord, whether such award shall be made as compensation for
diminution in value of the leasehold or for the taking of the fee, or as
severance damages; provided, however, that Tenant shall be entitled to any award
for loss of or damage to Tenant's trade fixtures and removable personal
property. In the event that this Lease is not terminated by reason of such
condemnation, Landlord shall, to the extent of severance damages received by
Landlord in connection with such condemnation, repair any damage to the Premises
caused by such condemnation except to the extent that Tenant has been reimbursed
therefor by the condemning authority.

14.      Real Estate Brokers. Tenant represents and warrants that it has not
authorized or employed, or acted by implication to authorize or to employ, any
real estate broker or salesman to act for Tenant in connection with this Lease,
except as otherwise noted in Schedule A. Tenant shall hold Landlord harmless
from and indemnify and defend Landlord against any and all claims by any other
real estate broker or salesman for a commission or finder's fee as a result of
Tenant's entering into this Lease.

15.      Estoppel Certificate.

         (a) Tenant shall, at any time upon not less than ten (10) days' prior
written request from Landlord, execute, acknowledge and deliver to Landlord a
statement in writing (i) certifying that this Lease is unmodified and in full
force and effect (or, if modified, stating the nature of such modification and
certifying that this Lease, as so modified, is in full force and effect) and the
date to which the rent and other charges are paid in advance, if any, (ii)
acknowledging that there are not, to Tenant's knowledge, any uncured defaults on
the part of Landlord hereunder, or specifying such defaults if any are claimed,
and (iii) certifying or acknowledging facts as to such other matters as Landlord
may reasonably require. Any such statement may be conclusively relied upon by
any prospective purchaser or encumbrancer of the Premises.

         (b) At Landlord's option, Tenant's failure to deliver such statement
within such time shall be conclusive upon Tenant, (i) that this Lease is in full
force and effect, without modification, except as may be represented by
Landlord, (ii) that there are no uncured defaults in Landlord's performance,
(iii) that not more than one month's rent has been paid in advance, and (iv)
that such other matters as to which Landlord has requested information are as
represented by Landlord, or such failure may be considered by Landlord as an
uncurable default by Tenant under this Lease five days after written notice has
been delivered to Tenant notifying Tenant of its failure to deliver the estoppel
certificate.

16.      Landlord's Liability. The term "Landlord" as used herein shall mean 
only the owner or owners at the time in question of the fee title or a tenant's
interest in a ground lease of the Premises, and in the event of any transfer of
such title or interest, Landlord herein named (and in case of any subsequent
transfers then the grantor) shall be relieved from and after the date of such
transfer of all liability as respects Landlord's obligations thereafter to be
performed, provided that any funds in the hands of Landlord or the then grantor
at the time 

                                      25.
<PAGE>   26
of such transfer, in which Tenant has an interest, shall be delivered to the
grantee and provided that Landlord (i.e., the party who is the Landlord after
the transfer) at the time of the transfer maintains $1.2 million of equity in
the project (as determined by the valuation any third-party lender to the
successor Landlord places upon the project). The obligations contained in this
Lease to be performed by Landlord shall, subject as aforesaid, be binding on
Landlord's successors and assigns only during their respective periods of
ownership.

17. Severability. The invalidity of any provision of this Lease as determined by
a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

18. Interest on Past-Due Obligations. Except as otherwise expressly herein
provided, any amount due to Landlord not paid when due shall bear interest at
the rate of 4% over the Wall Street Journal Prime Rate for the date the payment
is due, or, if less, the maximum rate then allowable by law, from the date due.
Payment of such interest shall not excuse or cure any default by Tenant under
this Lease, provided, however, that interest shall not be payable on late
charges incurred by Tenant nor on any amounts upon which late charges are paid
by Tenant.

19. Time of Essence. Time is of the essence.

20. Security Deposit. Upon execution of this Lease, Tenant shall deposit with
Landlord the sum specified on Schedule A, if any, as security for Tenant's
faithful performance of Tenant's, if any, obligations hereunder subject to
reduction as provided below. If Tenant fails to make any payment when due
hereunder, or otherwise defaults with respect to any provisions of this Lease,
Landlord may use, apply or retain all or any portion of said deposit for the
payment of such payment in default or for the payment of any other sum to which
Landlord may become obligated by reason of Tenant's default, or to compensate
Landlord for any loss or damage which Landlord may suffer thereby. If Landlord
so uses or applies all or any portion of said deposit, Tenant shall within ten
(10) days after written demand therefor deposit cash with Landlord in an amount
sufficient to restore said deposit to the full amount hereinabove stated, and
Tenant's failure to do so shall be a breach of this Lease. If Tenant performs
all of Tenant's obligations hereunder (except in case of a good faith dispute
over Operating Expenses), Landlord shall (upon Tenant's request therefor) refund
$10,000 of such security deposit on each of the first four anniversary dates of
the Term, and Tenant shall not after the fourth anniversary be required to
maintain any security deposit. If 0enant performs all of Tenant's obligations
hereunder, said deposit, or so much thereof as has not theretofore been applied
by Landlord, shall be returned to Tenant (or at Landlord's option, to the last
assignee, if any, of Tenant's interest hereunder) at the expiration of the term
hereof, and after Tenant has vacated the Premises. Landlord shall not be
required to keep this security deposit separate from its general funds, and
Tenant shall not be entitled to interest on such deposit. Upon termination of
the original Landlord's or any successor Landlord's interest in the Premises,
the original Landlord or such successor Landlord shall be relieved of further
liability with respect to the security deposit, provided that the amount thereof
in the hands of the original Landlord or such successor Landlord has been
delivered to the new owner of the Premises. No trust relationship is created
hereby between Landlord and Tenant with respect to said security deposit.

21. Incorporation of Prior Agreements; Amendments. This Lease contains all
agreements, oral or written, of the parties with respect to any matter mentioned
herein. No prior agreement or understanding pertaining to any such matter shall
be effective. There are no representations between Landlord and Tenant or
between any real estate broker and Tenant other than those contained in this
Lease. This Lease may be modified in writing only, signed by the parties in
interest at the time of the modification.

22. Notices. Any notice required or permitted to be given hereunder shall be in
writing and may be given by personal delivery, nationally recognized overnight
delivery service, or by registered or certified mail, return receipt requested.
If given personally, such notice shall be deemed sufficiently given if delivered
to any person apparently in charge or authorized to receive mail, or if given by
mail, shall be deemed sufficiently given if addressed to Tenant or to Landlord,
at the address noted in Schedule A or, if sent to Tenant subsequent to Tenant's
taking possession of the Premises, at the Premises. Any notice shall be deemed
to 

                                      26.
<PAGE>   27
have been given upon the date of personal delivery or, if mailed, three (3) days
after the date of mailing as provided herein. Either party may by notice to the
other specify a different address for notice purposes. A copy of all notices
required or permitted to be given to Landlord hereunder shall be concurrently
transmitted to such party or parties at such addresses as Landlord and Tenant
may from time to time hereafter designate, by notice, to the other party.

23.      Waivers. No waiver by Landlord or Tenant of any provision hereof shall
be deemed a waiver of any other provision hereof or of any subsequent breach by
Landlord or Tenant of the same or any other provision. Landlord's consent to, or
approval of any act, shall not be deemed to render unnecessary the obtaining of
Landlord's consent to or approval of any subsequent act by Tenant. The
acceptance of rent hereunder by Landlord shall not be a waiver of any preceding
breach by Tenant of any provision hereof, other than the failure of Tenant to
pay the particular rent, so accepted, regardless of Landlord's knowledge of such
preceding breach at the time of acceptance of such rent.

24.      Parking. Tenant shall be entitled to park in common with other tenants
of Landlord and shall have the nonexclusive right to use of the number of 
parking places set forth on Schedule A, or any lesser number which is now or
hereafter required under applicable laws or regulations affecting parking space
requirements. Tenant agrees not to overburden the parking facilities and agrees
to cooperate with Landlord and other tenants in the use of parking facilities.
Landlord reserves the right in its absolute discretion to determine whether
parking facilities are becoming crowded and, in such event, to allocate or
reallocate parking spaces among Tenant and other tenants.

25.      Holding Over. If Tenant, with Landlord's consent, remains in possession
of the Premises or any part thereof after the expiration of the term hereof,
such occupancy shall be a tenancy from month to month at a rental in the amount
of 150% the last Base Monthly Rent installment, plus all other Additional Rent
and charges payable hereunder during the option term, and upon all the other
provisions of this Lease pertaining to the obligations of Tenant, but all
options and rights of first refusal, if any, granted under the terms of this
Lease shall be deemed terminated and be of no further effect during said month
to month tenancy. Each party shall give the other written notice at least one
month prior to the date of termination of such monthly tenancy of its intention
to terminate.

26.      Cumulative Remedies.  No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

27.      Binding Effect; Choice of Law. Subject to any provisions hereof 
restricting assignment or subletting by Tenant and subject to the provisions of
Paragraph 16, this Lease shall bind the parties, their personal representatives,
successors and assigns. This Lease shall be governed by the laws of the State of
California.

28.      Subordination.

         (a) This Lease, at Landlord's option, shall be subordinate to any
ground lease, mortgage, deed of trust, or any other hypothecation for security
now or hereafter placed upon the real property of which the Premises are a part,
or to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Tenant's right to quiet possession of the
Premises shall not be disturbed so long as Tenant shall pay the rent and observe
and perform all the provisions of this Lease unless this Lease is otherwise
terminated pursuant to its terms. If any mortgagee, trustee or ground lessor
shall elect to have this Lease prior to the lien of its mortgage, deed of trust
or ground lease, and shall give written notice thereof to Tenant, this Lease
shall be deemed prior to such mortgage, deed of trust, or ground lease, whether
this Lease is dated prior or subsequent to the date of said mortgage, deed of
trust or ground lease or the date of recording thereof.

         (b) Tenant agrees to execute any documents containing nondisturbance
provisions as described in Paragraph 28(a) reasonably required to acknowledge or
effectuate an attornment, a subordination or to make this Lease prior to the
lien of any mortgage, deed of 

                                      27.
<PAGE>   28
trust or ground lease, as the case may be, and failing to do so within ten (10)
days after written demand does hereby make, constitute and irrevocably appoint
Landlord as Tenant's attorney in fact and in Tenant's name, place and stead, to
do so.

29. Attornment. In the event of foreclosure or the exercise of the power of sale
under any deed of trust made by Landlord covering the Premises (or a transfer
under a deed in lieu of foreclosure), Tenant shall attorn to the purchaser upon
any such foreclosure or sale (or to the grantee of such deed in lieu of
foreclosure), and Tenant shall recognize such purchaser or grantee as Landlord
under this Lease, provided such purchaser or grantee agrees in writing to
recognize all of Tenant's rights hereunder and to perform all of Landlord's
obligations hereunder from the date of the attornment.

30. Landlord's Access. Landlord and Landlord's agents shall have the right to
enter the Premises at reasonable times (including, in an emergency, immediate
entry without notice) for the purpose of inspecting the same, showing the same
to prospective purchasers, lenders, or tenants, making such alterations,
repairs, improvements or additions to the Premises or to the Building as
Landlord may deem necessary or desirable, and the erecting, use and maintenance
of utilities, services, pipes and conduits through the Premises, as long as
there is no material adverse effect upon Tenant's use of the Premises. Landlord
may at any time place on or about the Premises any ordinary "For Sale" signs,
and Landlord may, at any time during the last ninety (90) days of the term
hereof, place on or about the Premises any ordinary "For Lease" signs, all
without rebate of rent or liability to Landlord. Landlord shall retain a key to
all locked portions of the Premises (except vaults and locked file or storage
cabinets) at all times and shall have the right to unlock all doors. Tenant may
not change locks upon the Premises unless Tenant furnishes Landlord with a key
thereto. Tenant waives any claim or charges for damages or interference with
Tenant's property or business, any loss of quiet enjoyment or other loss
occasioned by Landlord's entry. Except in an emergency, Landlord shall effect
such entry in compliance with Tenant's reasonable security procedure.

31. Signs. Tenant may install on the Premises signs which identify Tenant and
the business Tenant conducts on the Premises, provided Tenant's signs comply
with (a) applicable requirements of governmental authorities, (b) applicable
recorded restrictions, and (c) Landlord's reasonable requirements, which may
include limitations on the number and placement of signs. Subject to compliance
with the foregoing requirements, Tenant may place a monument sign at the Camino
Ramon entrance to the Premises. In addition, subject to compliance with the
foregoing requirements, so long as Tenant leases the entire ground floor of the
Building, Landlord shall not allow any other tenant (or other person or entity)
to place a sign on the parapet of the Building. Tenant shall not install its
signs without Landlord's prior written approval which shall not be unreasonably
withheld or delayed. Tenant shall maintain its signs in neat condition and
repair throughout the Lease term. Tenant shall repair any damage which
maintenance, alterations or renovation of its signs may cause during or at the
expiration of the Lease term. Landlord agrees not to permit another tenant to
install parapet signs on the exterior top of the Building unless and until
Tenant ceases to lease the entire ground floor of the Building.

32. Merger. The voluntary or other surrender of this Lease by Tenant, or a
mutual cancellation thereof, or a termination by Landlord, shall not work a
merger, and shall, at the option of Landlord, terminate all or any existing
subtenancies or may, at the option of Landlord, operate as an assignment to
Landlord of any or all of such subtenancies.

33. No Light, Air or View Easement. Any diminution or shutting off of light, air
or view by any structure which may be erected on lands adjacent to the Premises
shall in no way affect this Lease or impose any liability on Landlord.

34. Consents. In any case in which either Landlord or Tenant is required to give
consent or approve any action of the other party under this Lease, such consent
shall not be unreasonably withheld or delayed.

35. Quiet Possession. Upon Tenant paying the rent for the Premises and observing
and performing all of the covenants, conditions and provisions on Tenant's part
to be observed 

                                      28.
<PAGE>   29
and performed hereunder, Tenant shall have quiet possession of the Premises for
the entire term hereof subject to all of the provisions of this Lease. The
individuals executing this Lease on behalf of Landlord represent and warrant to
Tenant that they are fully authorized and legally capable of executing this
Lease on behalf of Landlord, and that such execution is binding upon all parties
holding an ownership interest in the Premises.

36.      Landlord's Rules and Regulations. Tenant agrees that it will abide by,
keep and observe all reasonable rules and regulations which Landlord may make
from time to time for the management, safety, care and cleanliness of the
Building and grounds, the parking of vehicles and the preservation of good order
therein as well as for the convenience of other occupants and tenants of the
Building. Landlord's current Rules and Regulations, if any, are attached as
Exhibit D to this Lease, and Tenant shall faithfully comply with all such rules
and regulations and all reasonable modifications thereof and additions thereto
from time to time promulgated in writing by Landlord. The violation of any such
rules and regulations by Tenant shall be deemed a material breach of this Lease.
Landlord shall not be responsible to Tenant for the nonperformance of any such
rules and regulations by any other tenant of the Building or another Building
within the same complex.

37.      Security Measures. Tenant hereby acknowledges that the rental payable
to Landlord hereunder does not include the cost of guard service or other
security measures, and that Landlord shall have no obligation whatsoever to
provide the same. Tenant assumes all responsibility for the protection of
Tenant, its agents and invitees from acts of third parties. Nothing contained
herein shall prevent Landlord, at Landlord's sole option, from providing
security protection for the Building or any part thereof, in which event, the
cost thereof shall be included within the definition of Operating Expenses as
set forth in Paragraph 4.3.

38.      Landlord's Reservation of Rights.

         38.1 Easements. Landlord reserves to itself the right, from time to
time, to grant such easements, rights and dedications that Landlord deems
necessary or desirable and to cause the recordation of Parcel Maps and
restrictions, so long as such easements, rights, dedications, maps and
restrictions do not unreasonably interfere with the use of the Premises by
Tenant. Tenant shall sign any of the aforementioned documents upon request of
Landlord and failure to do so shall constitute a material breach of this Lease.

         38.2 Building Rights. Landlord shall have the right to (i) change the
name, address or title of the Building upon at least sixty (60) days' prior
written notice to Tenant, providing Landlord pays Tenant's reasonable costs of
printing new stationery reflecting such change; (ii) to, at Tenant's expense,
provide and install Building standard graphics on the door of the Premises and
such portions of the Common Areas as Landlord deems appropriate; (iii) to permit
any tenant the exclusive right to conduct any business as long as such exclusive
right does not conflict with any rights expressly granted herein; and (iv) to
place such signs, notices or displays as Landlord deems appropriate upon or
about the exterior of the Building or the Common Areas.

39.      Authority. If Tenant is a corporation, trust, or general or limited
partnership, each individual executing this Lease on behalf of such entity
represents and warrants that he or she is duly authorized to execute and deliver
this Lease on behalf of such entity.

40.      Conflict. Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions shall be controlled by the typewritten
or handwritten provisions.

41.      Attorneys' Fees. In the event of any action or proceeding at law or in
equity between Landlord and Tenant to enforce any provision of this Lease or to
protect or establish any right or remedy of either Landlord or Tenant hereunder,
the unsuccessful party to such action or proceeding shall pay to the prevailing
party all costs and expenses, including reasonable attorneys' fees, incurred in
such action or proceeding and in any appeal in connection therewith, and if such
prevailing party shall recover judgment

                                      29.
<PAGE>   30
in any such action, proceeding or appeal, such costs, expenses and attorneys'
fees shall be included in and as part of such judgment.

42.      Exhibits. The following exhibits are attached to this Lease and herein
incorporated by reference: Exhibit A (Site Plan); Exhibit B (Premises); Exhibit
C (Initial Improvements of Premises); Exhibit D (Rules and Regulations); Exhibit
E (Rules and Regulations for Tenant Contractors); and Exhibit F (CC&R's).

43.      Options.

         43.1 Options Personal. Any options ("Options") granted to Tenant in
this Lease (including, without limitation, the renewal option granted in
Paragraph 44, expansion rights granted in Paragraph 46, the cancellation right
granted in Paragraph 48, and the right of first offer granted in Paragraph 47)
are personal to Tenant and may not be exercised or be assigned, voluntarily or
involuntarily, by or to any person or entity other than Tenant; provided,
however, that any Option may be exercised by or assigned to any Tenant Affiliate
as defined in Paragraph 11.2 of this Lease and provided further than any Option
other than the expansion rights granted in Paragraph 46 may be assigned in
conjunction with an approved assignment of this Lease.

         43.2 Effect of Default on Option.

              (a) Tenant shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary, (i) during
the time commencing from the date Landlord gives to Tenant a notice of default
pursuant to Paragraph 12.1(c) and continuing until the default alleged in said
notice of default is cured, or (ii) during the period of time commencing on the
day after a monetary obligation to Landlord is due from Tenant and unpaid
(without any necessity for notice thereof to Tenant) continuing until the
obligation is paid, (except if there exists a bona fide dispute as to whether
such amounts are payable) or (iii) at any time after an event of default
described in Paragraph 12.1(a), 12.1(d), 12.1(e) or 12.1(f) (without any
necessity of Landlord to give notice of such default to Tenant), or (iv) in the
event there have been three or more defaults under Paragraph 12.1(b) during the
prior 12 months (except if there exists a bona fide dispute as to whether such
amounts are payable) where a late charge becomes payable under Paragraph 12.4
for each of such defaults, and/or notices of default under Paragraph 12.1(c),
whether or not the defaults are cured.

              (b) The period of time within which an Option may be exercised
shall not be extended or enlarged by reason of Tenant's inability to exercise an
Option because of the provisions of Subparagraph (a) above.

              (c) All rights of Tenant under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Tenant's due and
timely exercise of the Option, if any of the circumstances specified in (a)
above occurs after such exercise but prior to the time the Option takes effect.

44.      Extension Option. Landlord hereby grants to Tenant the option to extend
the term of this Lease (the "Extension Option") for one additional five-year
period. Tenant shall exercise such Extension Option by giving written notice of
exercise to Landlord at least six (6) months prior to the Expiration Date. All
of the terms and conditions of this Lease shall govern such extended term
insofar as applicable, and all references in this Lease to the term hereof shall
be deemed to include such extended term unless the context clearly indicates to
the contrary.

45.      Extended Term - Rent (Fair Market Value Determination).

         (a) The Base Monthly Rent for the Extension Option term shall be 95% of
the fair market rate for comparable space in the San Ramon and Pleasanton areas
as of the commencement of the Extension Option term as determined by the
agreement of the parties or, if the parties are unable to agree on or before
ninety (90) days prior to the expiration of the term, then by an appraisal
conducted pursuant to Subparagraph (b) below. The Base Monthly Rent shall take
into account the duration of the extension term and may provide for reasonable
periodic rental increases during such term.

                                      30.
<PAGE>   31
         (b) If it becomes necessary to determine the fair market rate for the
Premises by appraisal, then real estate appraiser(s), all of whom shall be
members of the American Institute of Real Estate Appraisers and shall have at
least two years' experience appraising commercial and industrial real property
located within the vicinity of the Premises, shall be appointed and shall act in
accordance with the following procedures:

             (i)   If Landlord and Tenant are unable to agree on the Monthly 
Base Rent for the Extension Option term, then either party may demand an
appraisal by giving written notice to the other party which demand to be
effective must state the name, address and qualifications of an appraiser
selected by the party demanding an appraisal (the "Notifying Party"). Within ten
(10) days following the Notifying Party's appraisal demand, the other party (the
"Non-Notifying Party") shall either approve the appraiser selected by the
Notifying Party or select a second properly qualified appraiser by giving
written notice of the name, address and qualifications of said appraiser to the
Notifying Party. If the Non-Notifying Party fails to select an appraiser within
the ten (10) day period, then the appraiser selected by the Notifying Party
shall be deemed selected by both parties and no other appraiser shall be
selected. If two appraisers are selected, they shall select a third
appropriately qualified appraiser. If the two appraisers fail to select a third
qualified appraiser within ten (10) days, then, upon application by either
party, the third appraiser shall be appointed by the President (or person
serving in comparable position, if there is no President) of the local Real
Estate Board (or any successor entity or body of comparable standing if such
Board does not then exist) or the person to whom the President may delegate that
function.

             (ii)  If only one appraiser is selected, then that appraiser shall
notify the parties in simple letter form of its determination of the fair market
rate for the Premises within thirty (30) days of his selection, which appraisal
shall be conclusively determinative and binding on the parties as the fair
market rent for the Premises.

             (iii) If multiple appraisers are selected, then the appraisers
shall meet not later than ten (10) days following selection of the last
appraiser. At such meeting, the appraisers shall attempt to determine the fair
market rate for the Premises as of the commencement date of the Option period by
the agreement of at least two of the appraisers.

             (iv)  The appraisers' determination of the fair market rate shall 
be based on a building of the same age, construction, size and location as the
Premises and shall take into account Tenant's obligation to pay additional rent
under the terms of this Lease. In determining the fair market rate, the
appraisers shall not consider any improvements, alterations, additions, fixtures
or equipment installed in the Premises at Tenant's expense, but shall include
improvements, alterations, additions, fixtures of equipment installed at
Landlord's expense. If two or more of the appraisers agree on the fair market
rate for the Premises at the initial meeting, then such agreement shall be
determinative and binding on the parties hereto, and the agreeing appraisers
shall, in simple letter form executed by the agreeing appraisers, forthwith
notify both Landlord and Tenant of the amount set by such agreement.

             (v)   If multiple appraisers are selected and the agreement of at
least two appraisers cannot be obtained within ten (10) days after the initial
meeting, then, within five (5) days after the expiration of said ten (10) day
period, all appraisers shall submit to Landlord and Tenant and independent
appraisal, in simple letter form, of the fair market rent for the Premises. The
parties shall then determine the appraised fair market rent for the Premises by
averaging the appraisals; provided, however, that (i) if the lowest appraisal is
less than eighty-five percent (85%) of the middle appraisal, then such lowest
appraisal shall be disregarded, and (ii) if the highest appraisal is greater
than one hundred fifteen percent (115%) of the middle appraisal, then such
highest appraisal shall be disregarded. If any appraisal is so disregarded, then
the average shall be determined by computing the average of the appraisals that
have not been disregarded.

             (vi)  Nothing contained herein shall prevent Landlord and Tenant
from jointly selecting a single appraiser to determine the fair market rate of
the Premises, in which 

                                      31.
<PAGE>   32
event, the determination of such appraisal shall be conclusively deemed to be
the fair market rate of the Premises for the Extension Option term in question.

             (vii) If only one appraiser is selected, then each party shall pay
half of the fees and expenses of that appraiser. If three appraisers are
selected, then each party shall bear the fees and expenses of the appraiser it
selects, plus half of the fees and expenses of the third appraiser.

46.      Expansion Option. Landlord hereby grants to Tenant the option (the
"Expansion Option") to lease from Landlord, in addition to the Premises, any
other portion of the Building in which the Premises are situated or, after its
initial lease-up, any portion of the building located at 4550 Norris Canyon Road
(hereinafter called the "Expansion Space"), at any time on or prior to April 15,
1998 that such space becomes available for Lease. Tenant's rights pursuant to
this Expansion Option shall be subordinate to any rights held by SBE or Biogenex
with respect to certain space consisting of approximately 9600 square feet
located at 4550 Norris Canyon Road, more specifically described and set forth in
Exhibit G, attached hereto ("Subordinated Space"). This expansion right shall
terminate immediately as to the building located at 4550 Norris Canyon Road upon
a sale or other transfer of such building to an unaffiliated third party. When
any such space becomes available, Landlord shall notify Tenant in writing of its
availability. Tenant shall exercise its Expansion Option by written notice
delivered to Landlord within ten days of receipt of Landlord's notice of
availability. If Tenant exercises its option to lease such Expansion Space, the
parties shall perform whatever acts are necessary to execute a lease thereof (or
an addendum hereto adding such Expansion Space to the Premises) within 30 days
after Tenant notifies Landlord of the exercise of Tenant's Expansion Option. Any
such lease by Tenant of any Expansion Space shall expire co- terminously with
the original Lease and shall be at the same rental per square foot of floor
space and upon all of the other terms and conditions of this Lease then in
effect; provided, however, that the tenant improvement allowance specified in
Exhibit C shall be reduced proportionately to the reduced initial term of this
Lease as it applies to the Expansion Space. If Tenant fails within the aforesaid
ten-day period to exercise its option to lease such Expansion Space hereunder,
it shall be conclusively presumed at the end of such ten-day period that Tenant
has waived its right to exercise such Expansion Option, but Tenant shall
thereafter retain its Right of First Offer under Paragraph 47 with respect to
such space. Such Expansion Option shall not be applicable to any space in the
Building which is subject to expansion or renewal options, or prior rights of
first offer or first refusal existing on the execution date hereof. Landlord
shall not be liable to Tenant for any failure of an existing occupant to vacate
Expansion Space leased by Tenant in a timely manner.

47.      Right of First Offer.

         (a) [intentionally deleted]

         (b) Grant of Right of First Offer. Landlord hereby agrees to notify
Tenant in writing, specifying the terms set forth in Subparagraph (c) below,
each time at least two thousand (2,000) contiguous square feet of space in the
Building becomes available for lease from Landlord (hereinafter the "Right of
First Offer"); provided, however, that such Right of First Offer shall not be
applicable to any space in the Building which is subject to expansion or renewal
options, or prior rights of first offer or first refusal existing on the
execution date hereof.

             Such Right of First Offer shall be nonexclusive. Landlord shall be
permitted to offer the space available to present or future tenants in the
Building whose leases contain similar rights of first offer at the same time as
such space is being offered to Tenant. In the event one or more other tenants
exercise rights of first offer and there is insufficient space available to
satisfy the requirements of all tenants, the space available shall be offered to
each tenant in proportion to the space requested in each tenant's Requirements
Notice. Furthermore, Tenant's rights pursuant to this Right of First Offer shall
be subordinate to any rights held by SBE and Biogenex with respect to the
Subordinated Space.

         (c) Offering Notice. Each notice made by landlord pursuant to
Subparagraph (b) above (the "Offering Notice") shall specify (i) the number of
square feet of space available 

                                      32.
<PAGE>   33
and the location of such space, (ii) the market rent and other charges at which
Landlord intends to offer such space, (iii) the value of leasehold improvements
or tenant allowance to be provided by Landlord for such space, if any, and (iv)
the estimated date that such space will be available for occupancy by Tenant.
Landlord hereby agrees that space offered to Tenant pursuant to this Right of
First Offer shall be offered at the rent and on the terms which Landlord in good
faith intends to offer to the general public. Tenant shall have fifteen (15)
days after receipt of the Offering Notice to accept or reject such space on the
terms specified in the Offering Notice. If Tenant rejects space offered pursuant
to an Offering Notice, Landlord's obligation to offer the particular such space
in question to Tenant in the future pursuant to this Right of First Offer shall
terminate.

         (d) Acceptance of Space. If Tenant desires to lease the space offered,
then Tenant shall have thirty (30) days to enter into a lease of such space on
the terms and conditions set forth in the Offering Notice and on such other
terms and conditions as Landlord offers to the general public (including any
increased rental or premium as a result of space rendered less marketable due to
Tenant's leasing of additional space) (hereinafter an "Expansion Lease");
provided, however, that (a) the term of any such Expansion Lease shall be
coterminous with the Lease (including any options to extend the term of the
Lease), and (b) if three (3) or less years remain in the term or any extended
term of the Lease (and Tenant has not exercised any remaining options to extend
the terms of the Lease) then (i) the rent provided in such Expansion Lease shall
be adjusted to reflect the cost of any tenant improvements or alterations borne
by Landlord amortized over the remaining term of the Lease at an interest rate
of 10%, or (ii) Tenant shall agree to pay to Landlord, at the end of the term of
such Expansion Lease, an amount equal to the portion of the cost of such tenant
improvements not recovered by Landlord pursuant to such Expansion Lease
(amortized at an interest rate of 10%).

         (e) Restrictions. Any space occupied pursuant to an Expansion Lease
shall be used and occupied only for the same uses permitted under this Lease,
except as otherwise agreed by Landlord. This Right of First Offer shall,
automatically and without notice, terminate upon (i) the termination of the
Lease for any reason; (ii) the subletting by Tenant at any one time of more than
25% of the Net Rentable Area of the Premises; (iii) the sale to an unaffiliated
third party of all or any portion of the Building by Landlord with regard to the
portion so sold. Furthermore, Tenant may not exercise any Right of First Offer,
and Landlord shall have no obligation to make such first offer to Tenant at any
time that Tenant is in default (as defined in Paragraph 12.1) of any of its
obligations under this Lease.

48.      Cancellation Right.

         (a) If, effective at any time from and after the end of the seventh
Lease year, Landlord fails to give Tenant notice of the availability of
additional space anywhere within the project commonly known as Norris Technology
Center sufficient to meet any expansion needs within 30 days of receipt of
Tenant's good faith written notification of its expansion requirements, Tenant
may elect to terminate this Lease upon at least 30 days' prior written notice.
Tenant shall exercise such election following the seventh anniversary of the
Commencement Date and within 30 days following Landlord's acknowledgement to
Tenant that it is unable to meet Tenant's expansion needs, by written notice to
Landlord specifying the intended Lease termination date and by making the
payment required by Subsection (b) below.

         (b) If Tenant exercises its right to terminate this Lease as provided
above, Tenant shall pay CalFront Associates (and not any successor landlord that
hereafter becomes Landlord under this Lease) on or prior to the termination
date: (i) unamortized leasing commissions; plus (ii) the unamortized portion of
Landlord's cost of Tenant's Initial Improvements constructed pursuant to Exhibit
C. Amortization shall be computed on a straight-line basis over the initial
ten-year term on the basis of the applicable principal amounts without interest.

49.      Moving Allowance. As an additional inducement to Tenant to enter into
this Lease, Landlord shall pay Tenant $1 per square foot of Net Rentable Area of
the Premises as a moving allowance to cover certain direct out-of-pocket costs
related to Tenant's relocation to 

                                      33.
<PAGE>   34
the Premises from its existing premises. Such allowance shall be payable upon
the initial Premises leased hereunder and any Expansion Space leased by the
Tenant pursuant to Paragraph 46 hereof. Such costs shall include the cost of
moving services and of replacing Tenant's existing supplies of stationery.
Landlord shall pay Tenant such amount within 30 days following submission of
invoices therefor in form reasonably satisfactory to Landlord.

                            (Signature Page Follows)

                                      34.

IN WITNESS WHEREOF, the parties hereto have executed this Lease as of the date
first above written.

                              Work Letter Agreement

1.       Landlord's Work.

         1.1 Landlord, through its general contractor, South Bay Construction
Company, shall furnish and install within the Premises those items of general
construction finally approved by Landlord and Tenant to build out the Premises
in accordance with the space plan attached as Exhibit ____ ("Landlord's Work")
as shown on the plans and specifications to be developed by Landlord's architect
or engineer (the "Final Plans and Specifications"), using Landlord's Building
standard materials, finishes and installations.

         1.2 Landlord's subcontractors for mechanical, electrical and fire
systems shall be selected by mutual agreement of Landlord and Tenant. The
construction contract shall require major subcontracts other than those for
mechanical, electrical and fire systems to be selected after three bids have
been obtained.

2.       Cost of Landlord's Work.

         2.1 As its contribution to the cost of Landlord's Work, Landlord shall
provide to Tenant a tenant improvement allowance equal to the cost of Landlord's
Work as shown on the Final Plans and Specifications as approved in Paragraph 1.1
above, up to $20 per square foot of Net Rentable Area. Tenant shall pay the cost
of all Landlord's Work in excess of such tenant improvement allowance as
provided in this Article 2. The cost of demolishing existing improvements and of
installing grade level loading doors shall be paid through the application of
such tenant improvement allowance except for the costs of demolishing existing
improvements in the portion of the space delineated on Attachment I as "former
DoD Space", which Landlord shall demolish at its sole cost. In addition,
Landlord shall bear the cost of any code compliance work required as a condition
to obtaining a building permit and not required by Tenant's special uses of the
Premises and the cost of providing a separate heating, ventilation and air
conditioning system to the Premises, which shall not be offset against the
tenant improvement allowance. If the Initial Improvement costs are less than the
full amount of Landlord's allowance, any unexpended balance up to $5 per square
foot of Net Rentable Area shall be credited towards Tenant's first payments of
Base Monthly Rent due under the Lease.

         2.2 Tenant shall bear the cost of Landlord's Work to the extent such
costs result from changes requested by Tenant to Final Plans and Specifications
or for requests for materials which cause the cost of Landlord's Work to exceed
the tenant improvement allowance.

         2.3 Landlord's obligation to perform Landlord's Work shall not require
Landlord to incur overtime costs and expenses and shall be subject to
unavoidable delays due to acts of God, governmental restrictions, strikes, labor
disturbances, shortages of material or supplies and any other cause or event
beyond Landlord's reasonable control.

         2.4 Tenant shall promptly pay Landlord during the course of
construction the cost of the work to be paid by Tenant under this Article 2,
based on invoices submitted by Landlord's contractor and certified by Landlord's
architect, so as to enable Landlord to pay Landlord's contractor without
advancing Landlord's funds for the cost of the work to be paid by Tenant.

         2.5 It is understood and agreed by Tenant that any minor changes from
any plans and specifications that may be reasonably necessary during
construction of the Premises shall not affect, change or invalidate this Lease.

                                       1.
<PAGE>   40
3.       Plans and Specifications.

         3.1 Landlord, through its architect and engineer, shall furnish all
architectural and engineering plans and specifications ("Plans and
Specifications") required to complete Final Plans and Specifications for the
construction of Landlord's Work.

         3.2 Tenant shall be furnished a copy of Final Plans and Specifications
and shall request any Tenant changes within seven days of submission to Tenant
by Landlord.

         3.3 Landlord shall bear the cost of architectural services for
Landlord's Work except as provided in Paragraph 3.4 below.

         3.4 Tenant shall pay the cost of any engineering services for
Landlord's Work. In addition, Tenant shall pay for any revisions required by
Tenant to Plans and Specifications previously approved by Tenant. The tenant
improvement allowance may be applied towards such architectural and engineering
costs.

4.       Tenant's Work.

         4.1 Any items or work not shown in the approved Final Plans and
Specifications, such as telephone service, furnishings or floor coverings for
which Tenant contracts separately (hereinafter "Tenant's Work") shall be subject
to Landlord's policies and schedules and shall be conducted in such as way as
not to hinder, cause any disharmony with, or delay work in the Building(s).
Tenant's suppliers, contractors, workmen and mechanics shall be subject to
approval by Landlord prior to the commencement of their work (which approval
shall not be unreasonably withheld or delayed) and shall be subject to
Landlord's administrative control while performing their work. If at any time
any supplier, contractor, workman or mechanic performing Tenant's Work hinders
or delays any other work in the Building(s) or performs any work which may or
does impair the quality, integrity or performance of any portion of the
Building(s), Tenant shall cause such supplier, contractor, workman or mechanic
to leave the Building(s) and remove all his tools, equipment and materials
immediately upon Landlord's notice delivered to Tenant. Tenant shall reimburse
Landlord for any repairs or corrections of Landlord's Work or of Tenant's Work
or of any portion of the Building(s) caused by or resulting from the work of any
supplier, contractor, workman or mechanic with whom Tenant contracts. Tenant
shall bear the cost of Landlord's expenses resulting from the performance of
Tenant's Work, including without limitation the cost of hoisting, cleaning,
security, administration and coordination by Landlord or Landlord's contractor.
Tenant shall reimburse Landlord for Landlord's reasonable direct out-of-pocket
costs for design reviews and approvals and reviews of construction progress, and
for the cost of all utilities and the services provided by Landlord to or for
the Premises during the performance of Tenant's Work. Landlord shall provide
access to Tenant's suppliers, contractors, workmen and mechanics so as to
achieve timely completion and occupancy of the Premises, if Landlord's
construction schedule permits such early entry and Tenant's early entry does not
interfere with Landlord's construction.

5.       [RESERVED]

6.       Completion Date.

         6.1 Landlord shall, when construction progress so permits, notify
Tenant, in advance, when it may enter the Premises for purposes of constructing
Tenant's Work as specified in Paragraph 4.1 of this Exhibit C, which shall be at
least 15 days prior to substantial completion of Landlord's Work in order to
allow Tenant to install Tenant's cabling, furniture and equipment. Landlord
shall also, when construction progress so permits, notify Tenant in advance of
the approximate date on which Landlord's Work will be substantially completed
and will notify Tenant when Landlord's Work is, in fact, substantially
completed, which latter notice shall constitute delivery of possession of the
Premises to Tenant. If any dispute shall arise as to whether the Premises are
substantially completed and ready for Tenant's occupancy, a certificate
furnished by Landlord's architect certifying the date of substantial completion
shall be conclusive of that fact and date and 

                                       2.
<PAGE>   41
binding upon Landlord and Tenant. If the Commencement Date is delayed because
Landlord is delayed in substantially completing said work as a result of:

             (a) Tenant's failure to furnish complete and timely instructions or
approvals,

             (b) Tenant's changes to any Plans and Specifications after approval
thereof,

             (c) Tenant's request for materials, finishes or installations other
than Landlord's Building standard, except as expressly provided in approved
Plans and Specifications, or

             (d) Hindrance or disruption of the work of Landlord's contractor
resulting from Tenant's Work, then the Commencement Date under the Lease shall
be advanced by the number of days of such delay.

         6.2 Failure by Tenant to meet any of the time requirements specified in
this Exhibit C shall, at Landlord's option, constitute a a default under the
Lease. Tenant shall not be entitled to a cure period with respect to any such
default.

         6.3 Except as expressly provided in the Lease, failure of Landlord to
deliver possession of the Premises within the time and in the condition provided
for in the Lease will not give rise to any claim for damages by Tenant against
Landlord or Landlord's contractor.

         6.4 Upon Landlord's delivery to Tenant of the notice of substantial
completion specified in Paragraph 6.1, Landlord and Tenant shall together hold a
walkthrough of the Premises. Landlord and Tenant shall identify those items

Committee. After Declarant ceases to perform the functions of the Architectual
Control Committee, the Architectual Control Committee shall be composed of three

until removed or replaced as provided for in this Declaration.

subject to this Declaration (excluding dedicated streets) shall have the right,
by recorded written notice executed by such owners, to remove and select one or
more of the members of the Architectual Control Committee, or to fill a vacancy
that occurs pursuant to Paragraph 4.5 and remains unfilled for a period of
thirty (30) days. Such recorded written notice shall specify the member being

performing duties on behalf of the Architectural Control Committee.

         4.5 Vacancies. A vacancy in the Architectural Control Committee shall
exist in the event of the death or resignation of any member or if the
authorized number of members is increased by an amendment to this Declaration.
The members of the Architectural Control Committee shall have the right to
declare an office of a member vacant by a vote of more than fifty percent (50%)
of the other members, if a member is found to be of unsound mind by a court,
convicted of a felony, or if within thirty (30) days after his election fails to

though they are less than a quorum. Written notice of any change in the members
of the Architectural Control Committee shall be recorded and a copy mailed to
each Owner. Such recorded written notice shall specify the member being replaced
and the name and address of the individual selected to the Architectural Control
Committee.

         4.6 Meetings, Quorum and Rules. Meetings may be called by any member of

be reviewed or approved by the Architectural Control Committee may be presented
to any member who shall then call a meeting of the Architectural Control
Committee upon at least forty-eight (48) hours prior notice to the other members
either by written notice or telephonic communication. A majority of the
authorized number of members constitutes a quorum of the Architectural Control
Committee and every act or decision done or made by a majority of the members
present is the act of the Architectural Control Committee. The members may adopt
by a majority vote of all the members such additional rules and procedures for
the running of the Architectural Control Committee, which rules shall be made
available to all Owners upon request.

         4.7 Approval of Plans. No improvement shall be erected, placed,
altered, remodeled, modified, removed, maintained or permitted to remain on any
of the Properties subject to this Declaration until plans and specifications
shall have been submitted to and approved in writing by the Architectural
Control Committee. Such plans and specifications shall be submitted in writing
in duplicate over the authorized signature of the Owner, lessee, licensee or
other occupant of the Lot or his authorized agent. Such plans and specifications
shall be in such form and shall contain such information as may be required by
the Architectural Control Committee, but in any event shall include:

              (a) A site development plan of the Lot showing the nature, grading
scheme, drainage plan, shape, materials and location with respect to the
particular Lot (including proposed front, rear and side setback lines) of all
structures, the location thereof with reference to structures on adjoining
portions of the property, and the number and location of all parking spaces and
driveways on the site;

              (b) a landscaping plan for the particular site;

              (c) A signing and lighting plan; and

                                       7.
<PAGE>   52
              (d) A building elevation plan showing dimensions, materials and
exterior color scheme and be in no less detail than required by the appropriate
governmental authority for the issuance of a building permit. Any changes in
approved plans which materially affect building size, placement or external
appearance shall be similarly submitted to and approved by the Architectural
Control Committee.

No improvement or structure shall be erected or placed on any Lot resulting from
the rearrangement or resubdivision of any of the Lots initially subject to this
Declaration or annexed pursuant to Section 2 unless approved by the Architectual
Control Committee in its sole discretion, provided that two or more Lots or
portions thereof may be combined to create one Lot and provided that three or
more Lots may be combined and resubdivided into Lots none of which shall contain
a lesser amount of square footage or less frontage than the smallest of such
Lots prior to such resubdivision.

         4.8 Basis for Approval. Approval shall be based, among other things, on
adequacy of site dimensions, coverage, adequacy of structural design, conformity
and harmony of external design with neighboring structures, effect of location
and use of proposed improvements on neighboring sites, proper facing of main
elevation with respect to nearby streets, adequacy of screening of mechanical
air conditioning or other roof top installations, and conformity of the plans
and specifications to the purpose and general plan and intent of this
Declaration. No plans will be approved which do not provide for the underground
installation of power, electrical, telephone and other utility lines from the
property line to buildings. The Architectural Control Committee shall not
arbitrarily or unreasonably withhold its approval of such plans and
specifications.

         4.9 Approval Process. Upon approval by the Architectural Control
Committee of any plans and specifications submitted hereunder, a copy of such
plans and specifications as approved, shall be deposited for permanent record
with the Architectural Control Committee, and a copy of such plans and
specifications bearing such approval, in writing, shall be returned to the
applicant submitting the same. If the Architectural Control Committee fails
either to approve or disapprove such plans and specifications within thirty (30)
days after the same have been submitted to it, it shall be conclusively presumed
that the Architectural Control Committee has approved said plans and
specifications; provided, however, that if within said 30-day period, the
Architectural Control Committee gives written notice of the fact that more time
is required for the approval of such plans and specifications, there shall be no
presumption that the same are approved until the expiration of a reasonable
period of time as set forth in said notice.

         4.10 Proceeding With Work. Upon receipt of approval from the
Architectural Control Committee pursuant to this Section 4, the Owner or lessee
to whom the same is given shall as soon as practicable, satisfy all conditions
thereof and diligently proceed with the commencement and completion of all
approved construction, refinishing, alterations and excavations. In all cases
work shall be commenced within one (1) year from the date of such approval, if
there is a failure to comply with this Paragraph 4.10, then the approval given
shall be deemed revoked unless the Architectural Control Committee upon request
made prior to the expiration of said one (1) year period extends the time for
commencing work.

         4.11 Completion of Work. In any event, reconstruction, refinishing or
alteration of any improvement shall be completed within two (2) years after the
commencement thereof except for so long as such completion is rendered
impossible or would result in great hardship due to strikes, fires, national
emergencies, natural calamities or other supervening forces beyond the control
of the Owner, lessee, licensee or occupant or his agents. Failure to comply with
this paragraph shall constitute a breach of this Declaration and subject the
defaulting party or parties to all enforcement procedures set forth in this
Declaration and any other remedies provided by law or in equity.

         4.12 Liability. The Architectural Control Committee shall not be liable
for any damage, loss or prejudice suffered or claimed on account of:

             (a) The approval or disapproval of any plans, drawings and
specifications, whether or not defective;

                                       8.
<PAGE>   53
             (b) The construction or performance of any work, whether or not
pursuant to approved plans, drawings and specifications; or

             (c) the development of any property within the Properties.

         4.13 Review Fee. An architectural review fee shall be paid to the
Architectural Control Committee at such time as plans and specifications are
submitted for approval and in such amounts as shall be established by a schedule
adopted from time to time by the Architectural Control Committee based on
reasonable costs incurred by the Architectural Control Committee for such
review.

         4.14 Construction Without Approval. If any improvement shall be
altered, erected, placed or maintained upon any Lot, or any new use commenced on
any lot, otherwise than in accordance with the approval by the Architectural
Control Committee pursuant to the provisions of this Section 4, such alteration,
erection, maintenance or use shall be deemed to have been undertaken in
violation of this Section 4 and without the approval required herein, and upon
written notice from the Architectural Control Committee, any such structure so
altered, erected, placed or maintained upon any lot in violation hereof shall be
removed or re-altered, and any such use shall be terminated so as to extinguish
such violation. If within fifteen (15) days after the notice of such violation
the Owner of the Lot upon which such violation exists shall not have taken
reasonable steps toward the removal or termination of the same, the
Architectural Control Committee shall have the right, through its agents and
employees, to enter upon such Lot, subject to any security controls imposed by
the Government of the United States (or any agency thereof) with respect to any
operation being conducted thereon, and to take such steps as may be necessary to
extinguish such violation. The Architectural Control Committee or any such agent
shall not thereby be deemed to have trespassed upon such Lot and shall be
subject to no liability to the Owner or occupant of such Lot for such entry and
any action taken in connection with the removal of any violation. The cost of
any abatement or removal hereunder shall be a binding personal obligation of
such Owner as well as a lien (enforceable in the same manner as a mortgage) upon
the Lot in question. The lien provided in this Section shall not be valid as
against a bona-fide purchaser (or bona fide mortgagee) of a Lot in question
unless a suit to enforce said lien shall have been filed in a court of record in
Contra Costa County, California, prior to the recordation of the deed (or
mortgage) conveying the Lot in question to such purchaser (or subjecting the
same to such mortgage).

         4.15 Minimum Setback Lines. No improvements of any kind, and no part
thereof, shall be placed closer than permitted by the Architectural Control
Committee to an interior property line but in no event closer than twenty (20)
feet. No improvements of any kind, and no part thereof, shall be placed closer
than thirty (30) feet from a property line fronting on any street as shown on a
map for all or a portion of the Properties.

         4.16 Exceptions to Setback Requirements. The following structures and
improvements are specifically excluded from the foregoing setback requirements:

              (a) Roof overhang subject to the specific approval of the
Architectural Control Committee in writing, provided it does not extend more
than six (6) feet into the setback area;

              (b) Steps and walks;

              (c) Paving and associated curbing except that vehicle parking area
shall not be permitted within five (5) feet of a property line fronting any
street;

              (d) Fences, except that no fence shall be placed within the street
setback area unless specific approval is given by the Architectural Control
Committee in writing;

              (e) Landscaping;

              (f) Planters, not to exceed three (3) feet in height, unless
specific approval is given by the Architectural Control Committee in writing;

                                       9.
<PAGE>   54
              (g) Signs identifying the Owner, lessee or occupant subject to the
specific approval of the Architectural Control Committee in writing; and

              (h) Lighting facilities, subject to the specific approval of the
Architectural Control Committee in writing.

         4.17 Landscaping. Every Lot on which a building shall have been placed
shall be landscaped in accordance with plans and specifications submitted to and
approved by the Architectural Control Committee pursuant to Section 4.
Landscaping as approved by the Architectural Control Committee shall be
installed within ninety (90) days of occupancy or completion of the building,
whichever occurs first, unless the Architectural Control Committee approves in
writing another completion date. After completion such landscaping shall be
maintained in a sightly and well-kept condition. The area of each site between
any street and any minimum setback line as defined by Paragraphs 4.15 and 4.16
shall be landscaped with an effective combination of street trees, trees, ground
cover and shrubbery. All other areas fronting on a street that are not utilized
for parking or driveways shall be landscaped in a similar manner. All areas of
each site not fronting on a street and not used for parking or storage shall be
landscaped utilizing ground cover and/or shrub and tree materials. Undeveloped
areas proposed for future expansion shall be maintained in a weed-free condition
and shall be landscaped if requested by the Architectural Control Committee.
Unpaved areas between the street curb line and the property line adjoining any
street shall be landscaped and maintained by Owner.

         4.18 Maintenance of Landscaping. If, in the opinion and sole discretion
of the Architectural Control Committee, the required landscaping is not
maintained in a sightly and well-kept condition, the Architectural Control
Committee shall have the right, through its agents and employees, to enter onto
any site and to take such steps as may be necessary to maintain the landscaping
in a sightly and well-kept condition. The Architectural Control Committee, or
any such agent or employee, shall not thereby be deemed to have trespassed upon
such site and shall be subject to no liability to the Owner or occupant of such
site for such entry and any action taken in connection with such necessary
maintenance. The cost of any such maintenance hereunder shall be a binding
personal obligation of such Owner, as well as a lien (enforceable in the same
manner as a mortgage) upon the site in question. The lien provided in this
Section shall not be valid as against a bona fide purchaser (or bona fide
mortgagee) of a site in question unless a suit to enforce said lien shall have
been filed in a court of record in Contra Costa County, California, prior to the
recordation of a deed (or mortgagee) conveying the site in question to such
purchaser (or subjecting the same to such mortgage).

         4.19 Adequate Parking Areas. Adequate off-street parking shall be
provided to accommodate all parking needs for employee, visitor and company
vehicles on the Lot. The intent of this provision is to eliminate the need for
any on-street parking; provided that this provision does not prohibit on-street
parking of public transportation vehicles. If parking requirements increase as a
result of a change in use or number of employees, additional off-street parking
shall be provided to satisfy the intent of this Paragraph. Required off-street
parking shall be provided on the site of the use served. Where parking is
provided on other than the Lot concerned, a recorded document shall be filed
with the Architectural Control Committee and signed by the Owners of the
alternate site stipulating to the permanent reservation of the use of the site
for said parking.

         4.20 Paved Parking Areas. Parking areas shall be paved so as to provide
dust- free, all-weather surfaces. Each parking space provided shall be
designated by lines painted on the paved surfaces and shall be adequate in area,
and all parking areas shall provide, in addition to parking spaces, adequate
driveways and space for the movement of vehicles. The number of parking spaces
required for each site, and the specific location of the same, shall be
designated in plans for each Lot which have been submitted and approved in the
manner set forth herein. In determining the number of parking spaces and the
location thereof of each site, the Architectural Control Committee shall
consider the exact nature of the use proposed for the site; the anticipated
number and manner of employment of persons on the site; the nature and location
of proposed structures on the site; and such other matters as the Architectural
Control Committee shall deem relevant. No parking spaces shall be located on,

                                      10.
<PAGE>   55
and no parking shall be permitted by the Architectural Control Committee within
designated setback areas adjacent to any street except that parking may be
permitted by the Architectural Control Committee within said setback area when
such parking is screened from view from the street by approved trees, screen
wall, shrubbery or berms.

         4.21 Storage and Loading Areas. Unless specifically approved by the
Architectural Control Committee in writing, no materials, supplies or equipment,
including company-owned or operated trucks and motor vehicles, shall be stored
in any area on a site except inside a closed building, or behind a visual
barrier screening such areas so that they are not visible from the neighboring
properties or public streets to a person six (6) feet tall standing at ground
level on such neighboring properties or public streets. Any storage areas
screened by visual barriers shall be located on the rear portions of the site,
unless approved by the Architectural Control Committee in writing. No storage
areas shall extend into setback lines as established herein unless approved by
the Architectural Control Committee in writing. All provisions for vehicle
loading shall be provided on the site with on-street vehicle loading not
permitted. No loading dock or trucking activity shall be permitted between the
structure and any street, and no loading area shall encroach into setback areas
unless specifically approved by the Architectural Control Committee. Loading
dock areas shall be set back and screened so as not to be visible from
neighboring properties and streets. No storage areas, loading docks, truck or
loading activity shall be permitted on a Lot adjoining Interstate Highway 680
unless specifically approved by the Architectural Control Committee.

5.       PROTECTION OF FIRST MORTGAGEES

         A breach of any of the provisions, covenants, restrictions or
limitations hereof, or the recordation of any assessment lien or the pursuit of
any remedy hereunder, shall not defeat or render invalid the lien of any first
Mortgage of record (meaning any recorded Mortgage or deed of trust with first
priority or security over other Mortgages or deeds of trust) made with an Owner
in good faith and for value upon the Lot of such Owner. All of the provisions
herein shall be binding upon and effective against any Owner whose title to said
Lot is hereafter acquired through foreclosure or trustee's sale. Each first
Mortgagee of a Mortgage encumbering any Lot in the Properties, which obtains
title to such Lot pursuant to the remedies provided in such Mortgage, by
judicial foreclosure or by deed or assignment in lieu of foreclosure, shall take
title to such Lot free and clear of any claims for unpaid assessments or
charges, if any, against such Lot which accrued prior to the time such holder
acquires title to such Lot.

6.       DURATION AND AMENDMENT

         6.1 Duration. This Declaration shall continue in full force for a term
of fifty (50) years from the date hereof, after which time the same shall be
automatically extended for successive periods of ten (10) years, unless a
Declaration of Termination is recorded in the Official Records, Contra Costa
County, California, meeting the requirements of an amendment to this Declaration
as set forth in Paragraph 6.2.

         6.2 Amendment. This Declaration or any provision thereof, or any
covenant, condition or restriction contained herein may be terminated, extended,
modified or amended, as to all or any portion of the Properties, with the
written consent of the Owners of sixty-six and two-thirds percent (66-2/3%) of
the real property then subject to this Declaration based on the number of acres
owned as compared to the total number of acres subject to this Declaration
(excluding dedicated streets), provided, however, that so long as Declarant owns
a Lot subject to the Declaration or for a period of fifteen (15) years from the
date of recordation of this Declaration, whichever period is longer, no such
termination, extension, modification or amendment shall be effective without the
written consent of the Declarant thereto. No such termination, extension,
modification or amendment shall be effective until a proper instrument in
writing has been executed, acknowledged and recorded. Notwithstanding the
foregoing, any of the following modifications or amendments, to be effective,
must be approved in writing by all of the institutional Mortgagees holding first
Mortgages encumbering the Lots in the Properties:

                                      11.
<PAGE>   56
             (a) Any amendment or modification which affects or purports to
affect the validity or priority of encumbrances or the rights, or protection
granted to encumbrancers as provided in Section 5 hereof; or

             (b) Any amendment or modification which would or could result in an
encumbrance being cancelled by forfeiture.

7.       GENERAL PROVISIONS

         7.1 Legal Proceedings. Failure to comply with any of the terms of this
Declaration, by an Owner, his guests, employees, invitees or tenants, shall be
grounds for relief which may include, without limitation, an action to recover
sums due for damages, injunctive relief, foreclosure of lien, or any combination
thereof, which relief may be sought by Declarant, the Architectural Control
Committee, or, if appropriate, by an aggrieved Owner. Failure to enforce any
provision hereof shall not constitute a waiver of the right to enforce said
provision, or any other provision hereof. The Declarant, the Architectural
Control Committee, any Owner (not at the time in default hereunder), shall be
entitled to bring an action for damages against any defaulting Owner, and in
addition may enjoin any violation of this Declaration. Any judgment rendered in
any action or proceeding pursuant thereto shall include a sum for attorneys'
fees in such amount as the Court may deem reasonable, in favor of the prevailing
party. Each remedy provided for in this Declaration shall be cumulative and not
exclusive or exhaustive.

         7.2 Severability. The provisions hereof shall be deemed independent and
severable, and a determination of invalidity or partial invalidity or
unenforceability of any one provision or portion hereof by a court of competent
jurisdiction shall not affect the validity or enforceability of any other
provisions hereof.

         7.3 Interpretation. The provisions of this Declaration shall be
liberally construed to effectuate its purpose of creating a uniform plan for the
creation and operation of an industrial and business park development and any
violation of this Declaration shall be deemed to be a nuisance. The section and
paragraph headings, titles and captions have been inserted for convenience only,
and shall not be considered or referred to in resolving questions of
interpretation or construction. As used herein, the singular shall include the
plural and the masculine, feminine and neuter shall mean the same. This
Declaration shall be construed and enforced in accordance with the laws of the
State of California.

         7.4 Construction and Sales by Declarant. Nothing in this Declaration
shall limit, and no Owner shall do anything which shall interfere with, the
right of Declarant to complete any construction of improvements on the Lots
owned by Declarant, or to alter the foregoing and its construction plans and
designs, or to construct such additional improvements on such Lots as Declarant
deems advisable prior to completion and sale of the last Lot in the Properties.
Each Owner by accepting a deed to a Lot hereby acknowledges that the activities
of Declarant may constitute a temporary inconvenience or nuisance to the Owners
and hereby consents to such inconvenience or nuisance. Each Owner hereby grants,
upon acceptance of his deed to his Lot, an irrevocable, special power of
attorney to Declarant to execute and record all documents and maps necessary to
allow Declarant to exercise its rights under this Paragraph 7.4. Such right
shall include, but shall not be limited to, erecting, constructing and
maintaining on the Properties such structures and displays as may be reasonably
necessary for the conduct of its business of completing the work and disposing
of the same by sale, lease or otherwise. Declarant may use any Lots owned by
Declarant in the Properties as models or real estate sales or leasing offices.
This Declaration shall not limit the right of Declarant at any time prior to
acquisition of title to the last Lot in the Properties by a purchaser from
Declarant, to establish on the Lots owned by Declarant easements, reservations
and rights-of-way to itself, to utility companies, or to other Persons as may
from time to time be reasonably necessary to the proper development and disposal
of the Properties. Such easements may be created for the construction,
installation, maintenance, removal, replacement, operation and use of utilities,
including without limitation, sewers, water and gas pipes and systems, drainage
lines and systems, electric power and conduit lines and wiring, telephone
conduits, lines and wires, and other utilities, public or private, beneath the
ground surface (except vaults, vents, access structures and other facilities

                                      12.
<PAGE>   57
required to be above ground surface by good engineering practice), including the
right to dedicate, grant or otherwise convey easements or rights-of-way to any
public utility or government entity for such purposes. All or any portion of the
rights of Declarant hereunder may be assigned to any successor or successors to
all or part of Declarant's respective interest in the Properties, or to any
other person designated by Declarant by an express written assignment recorded
in the Office of the Contra Costa County Recorder. Declarant need not seek or
obtain the approval of the Architectural Control Committee in connection with
any improvements constructed or altered by Declarant in the Properties.

         7.5 No Public Right or Dedication. Nothing contained in this
Declaration shall be deemed to be a gift or dedication of all or any part of the
Properties to the public, or for any public use.

         7.6 Designation of Owners Representative. Upon the conveyance of a Lot
to an Owner and on July 1, of each year, Owner shall provide by written notice
to the Architectual Control Committee the name of an individual and his address
who shall be the Owner's Representative. The Owner's Representative shall be
deemed to have the power to bind the Owner in connection with any matter arising
under this Declaration and any notice delivered to the Owner's Representative
shall be deemed notice to the Owner. Each Owner shall have the right to
designate a replacement Representative by compliance with the provisions of this
Paragraph 7.6.

         7.7 Notices. Except as otherwise provided in this Declaration, in each
instance in which notice is to be given to an Owner, the same shall be in
writing and may be delivered personally to the Owner's Representative, as
designed pursuant to Paragraph 7.6. In the event that a Representative for an
Owner has not been designated, personal delivery of such notice to one or more
co-owners of a Lot or to any general partner of a partnership owning a Lot shall
be deemed delivery to all co-owners or to the partnership, as the case may be
and personal delivery of such notice to any officer or agent for the service of
process on a corporation shall be deemed delivery to the corporation. In lieu of
the foregoing, such notice may be delivered by regular United States mail,
postage prepaid, addressed to the Owner's Representative at the most recent
address furnished by such Owner or to the street address of such Owner's Lot.
Such notice shall be deemed delivered at the beginning of the second day after
the day of such mailing.

         THIS DECLARATION has been executed on the date first written above.
