                      AGREEMENT AND PLAN OF REORGANIZATION


         THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is entered
into as of the 6th day of June, 1997, by and among Giga-tronics Incorporated, a
California corporation ("Giga-tronics"), GTV Acquisition Corp., a California
corporation and a wholly owned subsidiary of Giga-tronics ("Merger Sub"), and
Viking Semiconductor Equipment, Inc., a California corporation ("Viking").


                                    RECITALS

         A. The Boards of Directors of Giga-tronics, Merger Sub and Viking have
each determined to engage in the transactions contemplated hereby, pursuant to
which (i) Merger Sub will merge (the "Merger") with and into Viking, (ii) each
share of common stock, no par value, of Viking ("Viking Common Stock") and any
other shares of Viking stock which shall have previously been converted into
Viking Common Stock (except for shares of Viking 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 Viking Common Stock, all upon the terms and subject to the conditions
set forth herein.

         B. The Board of Directors of Viking has approved, and has resolved to
recommend that the shareholders of Viking 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. 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.

                                    ARTICLE I

                                   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 Viking (the "Merger"), as soon as practicable following the satisfaction or
waiver of the conditions set forth in Article VIII hereof. Following the Merger,
Viking 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 Viking 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 Viking 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, 1997 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 Viking 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 Viking Common Stock
                  issued and outstanding immediately prior to the Effective Time
                  (other than Dissenting Viking Shares (as defined in Section
                  1.04 hereof))(the "Viking Shares") shall automatically, by
                  virtue of the Merger and without any action on the part of the
                  holder thereof, be converted into a right to receive the
                  number of shares of Giga-tronics Common Stock as is determined
                  pursuant to this Section 1.02. A maximum total of 420,000
                  shares of Giga-tronics Common Stock (the "Merger
                  Consideration") will be issued in the Merger, including shares
                  that would have been issued to holders of Dissenting Viking
                  Shares and fractional shares that would have been issuable but
                  for Section 1.05 below.





                                       2.


<PAGE>   8



                           (ii) The Agreement of Merger to be filed shall
                  contain the final exchange ratio (the "Exchange Ratio") for
                  Viking Shares into Giga-tronics Common Stock and shall be
                  equal to 420,000 divided by the fully diluted number of Viking
                  Shares outstanding at the Effective Time (the "Viking
                  Outstanding Equivalent Number"). The Viking Outstanding
                  Equivalent Number shall be equal to the sum of (1) the number
                  of Viking Shares outstanding at the Effective time; plus (2)
                  the total number of Viking Shares which would be issuable on
                  the exercise of any Viking warrants or options or other
                  securities convertible into, or exercisable for, Viking Shares
                  (collectively "Viking Options"). All Viking 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 Viking 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 Viking shareholders and, if applicable, the cash to
which holders of Viking 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 Viking 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 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 Viking 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.







                                       3.




<PAGE>   9



                  (d) After the Effective Time there shall be no transfers on
the stock transfer books of either Viking (the stock transfer books of which
shall be closed) or the Surviving Corporation of Viking 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. Viking 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 Viking 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
Viking Shares pursuant to the law of the State of California. If a holder of
Dissenting Viking 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 Viking Shares shall cease to be Dissenting Viking Shares and shall be
converted into the right to receive, and shall be exchangeable for, the Merger
Consideration into which such Dissenting Viking Shares would have been converted
pursuant to Section 1.02(a) hereof. Viking shall give Giga-tronics prompt notice
of any demand received by Viking from a holder of Dissenting Viking Shares for
appraisal of Viking Shares, and Giga-tronics shall have the right to participate
in all negotiations and proceedings with respect to such demand. Viking 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 Viking 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 Viking Shares shall be retained by
Giga-tronics.

         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 Viking 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 Viking 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.


                                       4.

         SECTION 1.06 VIKING OPTIONS. Giga-tronics will not assume any Viking
Options. At the Effective Time, any outstanding Viking Options shall be deemed
exercised for such number of shares of Giga-tronics Common Stock as would be
exchanged in the Merger for the Viking Shares which would have been issued had
such Viking Options been exercised in full and such Viking Shares been
outstanding immediately prior to the Effective Time, subject to the following
provisions of this Section 1.06. Such deemed exercise of Viking Options shall be
on a "net exercise" basis. The full number of shares issuable on exercise of
such Viking Option (including such number of shares as are deemed surrendered in
the net exercise) shall be added to the Viking Outstanding Equivalent Number as
described in Section 1.02 above. The value of the Viking Shares issuable on the
exercise of any Viking Option for purposes of determining the number of Viking
Shares to be surrendered in the deemed net exercise shall be equal to the number
of Viking Shares issuable on exercise of such Viking 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
Viking Shares deemed surrendered upon such net exercise shall be retained by
Giga-tronics.

         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.

(vii) there are no pending, or, to the best knowledge of Viking after due
inquiry, threatened claims against Viking relating to any Environmental Law or
Hazardous Substance.

         SECTION 3.18 INTELLECTUAL PROPERTY. No claim is pending or, to the
knowledge of Viking, threatened to the effect that the present or past
operations of Viking 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 Viking to conduct its business as now operated
(the "Viking Intellectual Property"), except as disclosed in the Viking
Disclosure Schedule, no claim is pending or, to the best knowledge of Viking,
threatened to the effect that any of the Viking Intellectual Property is invalid
or unenforceable. Viking 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 Viking and each of its
subsidiaries. Except as set forth in the Viking Disclosure Schedule, no
contract, agreement or understanding between Viking or any of its subsidiaries
and any other party exists which would impede or prevent the continued use by
Viking and its subsidiaries of the entire right, title and interest of Viking
and its subsidiaries in and to the Viking Intellectual Property.

         SECTION 3.19 NO GUARANTIES. None of the obligations or liabilities of
Viking is guaranteed by, or subject to a similar contingent liability of, any
other person, firm or corporation, nor has Viking guaranteed, or otherwise
become contingently liable for, the obligations or liabilities of any other
person, firm or corporation.

         SECTION 3.20 ABSENCE OF CERTAIN BUSINESS PRACTICES. Neither Viking nor
any officer, employee or agent of Viking, 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 Viking (or assist Viking in connection with any actual or proposed
transaction) which (a) might subject Viking 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 Viking as reflected in the Financial Statements or (c) if not continued in
the future, might adversely affect Viking's assets, business, operations or
prospects or which might subject Viking to suit or penalty in any private or
governmental litigation or proceeding.

         SECTION 3.21 COMPLIANCE WITH LAWS AND OTHER INSTRUMENTS. Viking 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 Viking'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,





                                       15.

ordinance, rule or regulation, or any order, judgment or decree to which Viking
is a party or by which it may be bound or affected. Neither Viking nor any
Shareholder is aware of any proposed laws, rules, regulations, ordinances,
orders, judgments, decrees, governmental takings, condemnations 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 Viking for inclusion in the information materials relating to
the solicitation of the approval of Viking's shareholders of the Merger (the
"Information Materials") at the time of mailing of the Information Materials to
shareholders of Viking, and at the time of the meeting of Viking shareholders to
be held in connection with the Merger or action by written consent of
shareholders approving 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.

         SECTION 3.23 TAX MATTERS. Neither Viking 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 Viking 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 Viking Disclosure
Schedule sets forth all persons who, as of the date of this Agreement, may be
deemed to be affiliates of Viking 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, Viking 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.

         SECTION 3.25 RESTRICTIONS ON BUSINESS ACTIVITIES. There is no agreement
(non-compete or otherwise), commitment, judgment, injunction order or decree to
which Viking is a party or otherwise binding upon Viking which has or could
reasonably be expected to have the effect of prohibiting or impairing any
business practice of Viking, any acquisition of property by Viking or the
conduct of business by Viking. Without limiting the foregoing, Viking has not
entered into any agreement under which Viking is restricted from selling,
licensing or otherwise distributing any of its products.

         SECTION 3.26 INTERESTED PARTY TRANSACTIONS. No officer, director or
stockholder of Viking (nor any ancestor, sibling, descendant or spouse of any
such person, or any trust, partnership or corporation in which any of such
persons has or has had an interest) has or has had, directly or indirectly, (i)
an economic interest in any entity which furnished or sold, or furnishes or
sells, services or products that Viking furnishes or sells or proposes to
furnish or sell, or (ii) an economic interest in any entity that purchases from,
or sells or furnishes to, Viking any goods





                                       16.

or services; provided that ownership of no more than one percent (1%) of the
outstanding voting stock of a publicly traded corporation shall not be deemed an
"economic interest in any entity" for purposes of this Section 3.26.

group of affiliated persons other than current security holders of Viking
acquire securities of Viking representing more than 20% of the aggregate voting
power of Viking'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

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 Viking 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,
Viking 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






                                       24.

writs, injunctions, judgments, statutes, rules and regulations applicable to
Viking and its properties or assets.

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

that the consent of such person is or may be required in connection with the
Merger;

Merger.

         SECTION 5.08 CONFIDENTIALITY. Viking agrees that for a period of three
years following any termination of this Agreement Viking shall not (a) disclose
to any person, association, firm, corporation or other entity in any manner,
directly or indirectly, any confidential information or data relevant to the
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

competitive with the operations of Giga-tronics excepting only use of (i)
information in the public domain at the time of disclosure to Viking (ii)
information subsequently coming into the public domain by means other than
disclosure by Viking or any of its agents (iii) information Viking can establish
and document was in its possession or was known to it prior to its disclosure to
Viking by Giga-tronics; (iv) information disclosed to Viking by a third party
not in violation of any obligation of confidentiality or nondisclosure known to
Viking or of which Viking should reasonably have known; or (v) information which
was independently developed by Viking or which is generally known in Viking's
industry.

         SECTION 5.09 COMPLIANCE WITH THE SECURITIES ACT. Viking shall prior to
15 days after signing but in any event prior to mailing of the Information
Materials 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 Viking to
deliver to Giga-tronics an Affiliates Agreement in substantially the form
attached hereto as Exhibit 5.09 (an "Viking Affiliates Agreement").

         SECTION 6.08 COMPLIANCE WITH THE SECURITIES ACT. Giga-tronics shall use

                                   ARTICLE VII

                         OTHER COVENANTS OF THE PARTIES

         The Parties agree that:

         SECTION 7.01 ADVICE OF CHANGES. Each party will promptly advise each
other party in writing (i) of any event known to its executive officers
occurring subsequent to the date of this Agreement that would render any
representation or warranty of such party contained in this Agreement, if made on
or as of the date of such event or the Effective Date, untrue, inaccurate or
misleading in any material respect (other than an event so affecting a
representation or warranty which is expressly limited to a state of facts
existing at a time prior to the occurrence of such event) and (ii) of any
Material Adverse Change in the business condition of the party and its
Subsidiaries, taken as a whole.

         SECTION 7.02 REGULATORY APPROVALS. Prior to the Effective Time, each
party shall execute and file, or join in the execution and filing of, any
application or other document that may be necessary in order to obtain the
authorization, approval or consent of any governmental body, federal, state,
local or foreign, which may be reasonably required, or that the other company
may reasonably request, in connection with the consummation of the Merger. Each
party shall use its reasonable best efforts to obtain all such authorizations,
approvals and consents.

         SECTION 7.03 ACTIONS CONTRARY TO STATED INTENT. No party hereto shall,
from or after the date hereof and either before or after the Effective Time,
take any action that would prevent the Merger from qualifying as a
reorganization under Section 368 of the Code.

another:

                  (c) in determining whether any action by or in respect of, or

                                       28.


<PAGE>   34



                  (d) in seeking any such actions, consents, approvals or
waivers or making any such filings, furnishing information required in
connection therewith and seeking timely to obtain any such actions, consents,
approvals or waivers.

         SECTION 7.05 COMMUNICATIONS. Between the date hereof and the Effective
Time, no party will furnish any written communication to its shareholders or to
the public generally if the subject matter thereof relates to the transactions
contemplated by this Agreement without the prior approval of Viking and

withheld; provided that the foregoing shall not be deemed to prohibit any
disclosure required by any applicable law or by any competent governmental
authority.

         SECTION 7.06 SATISFACTION OF CONDITIONS PRECEDENT. The parties will use
their reasonable best efforts to satisfy or cause to be satisfied all the
conditions precedent that are set forth in Article VIII, as applicable to each
of them, and to cause the transactions contemplated by this Agreement to be

required on its part in order to effect the transactions contemplated hereby.


                                  ARTICLE VIII

                            CONDITIONS TO THE MERGER

         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 Viking 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
Viking shall have provided Giga-tronics with a certificate executed by the
President and the Chief Financial Officer of Viking, 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 Viking 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 subsidiaries, taken as a whole; and "Material Adverse
Change" shall






                                       29.

<PAGE>   35



mean a change or a development involving a prospective change which would have a
Material Adverse Effect.

                  (b) Covenants. Viking 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 Viking's President and Chief Financial Officer.

                  (c) No Material Adverse Change. There shall have been no
Material Adverse Change in Viking since the Viking 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 Viking 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 Viking by May 25, 1997 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 Viking. 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 Viking,
Giga-tronics shall promptly notify Viking 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 Viking Shares which are voted against the Merger or
which have abstained from voting with respect to the Merger.

         SECTION 8.02 CONDITIONS TO OBLIGATIONS OF VIKING. Viking's obligations
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 Viking, but only in a writing signed by Viking):

                  (a) Accuracy of Representations and Warranties. The
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 Viking 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-






                                      30.

<PAGE>   36

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 Articles VI and VII in all material
respects on or before the Effective Date, and Viking 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 Viking 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. Viking's 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 Viking 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 Viking and the
Giga-tronics tax opinions, Brobeck may rely on (and to the extent reasonably
required, the parties and Viking'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 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 Viking 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 Viking 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









                                       31.




<PAGE>   37



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, Viking or the Surviving Corporation or
would be reasonably likely to subject any of Giga-tronics, Merger Sub, Viking 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.


                                   ARTICLE IX

                            TERMINATION OF AGREEMENT

         SECTION 9.01 TERMINATION. This Agreement may be terminated at any time

         Giga-tronics, Merger Sub and Viking;

                  (b) by either Giga-tronics and Merger Sub or Viking, if the
         requisite approval of the shareholders of Viking shall not be obtained
         by August 1, 1997;

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

                           (i) withdrawn its recommendation of the Merger, or

                           (ii) 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



                  (d) by either Giga-tronics and Merger Sub or Viking,
         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
         Viking 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

                  (e) by Giga-tronics, if the conditions contained in Section
         8.01(f) are not satisfied; or






                                       32.

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

                  (g) by either Giga-tronics and Merger Sub or Viking,
         respectively, at any time after August 1, 1997, 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
Viking, 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.

                              AGREEMENT OF MERGER


                 This Agreement of Merger, dated as of _______________, 199__
("Merger Agreement"), is made and entered into by GTV Acquisition Corp., a
California corporation ("GTV"), Viking Semiconductor Equipment, Inc., a
California corporation ("Viking") (GTV and Viking being collectively referred
to as the "Constituent Corporations") and Giga-tronics Incorporated, a
California corporation ("Giga-tronics").

                                  WITNESSETH:

                 WHEREAS, the Constituent Corporations and Giga-tronics
previously have entered into an Agreement and Plan of Reorganization (the
"Agreement and Plan of Reorganization") providing for certain representations,
warranties and agreements in connection with the transactions contemplated; and

                 WHEREAS, the Boards of Directors of the Constituent
Corporations deem it advisable and in the best interests of the Constituent
Corporations and in the best interests of the shareholders of the Constituent
Corporations that GTV merge (the "Merger") with and into Viking.


                 NOW, THEREFORE, the Constituent Corporations and Giga-tronics
hereby agree as follows:


                                   ARTICLE I.

                          The Constituent Corporations

                 1.01     (a)     Viking was incorporated under the laws of the
State of California on December 16, 1983.

                          (b)     Viking is authorized to issue an aggregate of
100,000 Common Shares (the "Viking Common Stock").

                          (c)     As of the date and time immediately prior to
the consummation of the Merger, there will be an aggregate of 27,313 shares of
Viking Common Stock outstanding.

                 1.02     (a)     GTV was incorporated under the laws of the
State of California on April 7, 1997.




<PAGE>   45
                          (b)     GTV is authorized to issue an aggregate of
1,000 shares of common stock ("GTV Common Stock").

                          (c)     As of the date and time immediately prior to
the consummation of the Merger, an aggregate of 1,000 shares of GTV Common
Stock were outstanding and owned by Giga-tronics.


                                  ARTICLE II.

                                   The Merger

                 2.01     (a)     This Merger Agreement shall be submitted to
the shareholders of Viking and GTV.  If adopted and approved by the
shareholders of Viking and GTV and if all of the conditions precedent to the
consummation of the Merger specified in the Agreement and Plan of
Reorganization shall have been satisfied or duly waived by the party entitled
to satisfaction thereof, then, unless terminated as provided in the Agreement
and Plan of Reorganization, this Merger Agreement, along with certificates
meeting the requirements of the California General Corporation Law, shall be
filed with the Secretary of State of California.  Upon such filing, the Merger
shall become effective ("Effective Time of the Merger").

                          (b)     At the Effective Time of the Merger, GTV
shall be merged into Viking and the separate corporate existence of GTV shall
thereupon cease.  Viking shall be the surviving corporation in the Merger (the
"Surviving Corporation") and the separate corporate existence of Viking, with
all of its purposes, objects, rights, privileges, powers, immunities and
franchises, shall continue unaffected and unimpaired by the Merger.

                 2.02     (a)     The Surviving Corporation shall succeed to
all of the rights, privileges, powers, immunities and franchises of GTV, all of
the properties and assets of GTV and all of the debts, choices in action and
other interests due or belonging to GTV and shall be subject to, and
responsible for, all of the debts, liabilities and obligations of GTV with the
effect set forth in the California General Corporation Law.

                          (b)     If, at any time after the Effective Time of
the Merger, the Surviving Corporation shall consider or be advised that any
deeds, bills of sale, assignments, assurances or any other actions or things
are necessary or desirable to vest, perfect or confirm of record or otherwise
in the Surviving Corporation its right, title or interest in, to or under any
of the rights, properties or assets of GTV acquired or to be acquired by the
Surviving Corporation as a result of, or in connection with, the Merger or to
otherwise carry out this Merger Agreement, the officers and directors of the
Surviving Corporation shall and will be authorized to execute and deliver, in
the name and on behalf of the Constituent Corporations or otherwise, all such
deeds, bills of sale,





                                       2.
<PAGE>   46
assignments and assurances and to take and do, in the name and on behalf of the
Constituent Corporations or otherwise, all such other actions and things as may
be necessary or desirable to vest, perfect or confirm any and all right, title
and interest in, to and under such rights, properties or assets in the
Surviving Corporation or to otherwise carry out this Merger Agreement.


                                  ARTICLE III.

                           Articles of Incorporation

                 3.01     The Articles of Incorporation of Viking in effect
immediately prior to the Effective Time of the Merger shall be amended and
restated to read as attached at Exhibit 1.


                                  ARTICLE IV.

                     Manner And Basis Of Converting Shares
                        Of The Constituent Corporations

                 4.01     At the Effective Time of the Merger:

                          (a)     Each share of GTV 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 Viking Common Stock.

                          (b)     Each share of Viking Common Stock (except for
shares, if any, which shall then or thereafter constitute "dissenting shares"
within the meaning of Section 1300 of the California General Corporation Law
and those shares of GTV Common Stock converted to shares of Viking Common Stock
Pursuant to Section 4.01(a) above) which is outstanding immediately prior to
the Effective Time of the Merger shall be converted at the Effective Time of
the Merger into [______ 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 Common Stock or any Giga- tronics
certificates representing fractional shares of Giga-tronics Common Stock in
connection with any exchange of Viking certificates for Giga-tronics
certificates; however, Giga-tronics shall pay to each person who would
otherwise be entitled to receive an 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





                                       3.
<PAGE>   47

of Giga-tronics Common Stock on the last business day on which the Giga-tronics
Common Stock is traded on the NASDAQ National Market 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 shares of Viking Common
Stock, 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 share of Viking Common Stock 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 Common Stock 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.

                                    General

                 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
either of the Constituent Corporations, but, after any such approval, no
amendment shall be made which would have a material adverse effect on the
shareholders of either of the Constituent Corporations, 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.





                                       4.
<PAGE>   48

Without limiting the foregoing, the parties hereto acknowledge and agree that
any modification of the manner or basis of converting Viking Common Stock 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 Viking.

                 IN WITNESS WHEREOF, the parties have duly executed this Merger
Agreement as of the date first written above.

into as of this __ day of _____, 1997 among GIGA-TRONICS, INC., a California
corporation ("Giga-tronics"), the undersigned shareholder ("Shareholder")
of VIKING SEMICONDUCTOR EQUIPMENT, INC., a California corporation ("Viking"),
GTV ACQUISITION CORP., a California corporation and wholly owned subsidiary of
Giga-tronics ("MERGER SUB") and Viking.

                    This Agreement is entered into in connection with that
certain Agreement and Plan of Reorganization dated as of June 6, 1997 (the
"Reorganization Agreement") among Giga-tronics, Merger Sub, and Viking.  The
Reorganization Agreement provides for the merger (the "Merger") of Merger Sub
with and into Viking in a transaction in which issued and outstanding shares of
common stock, no par value, of Viking (the "Viking 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 Viking 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 Viking 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, Viking, and agrees that





                                       1.

their respective counsel and accounting firms and other stockholders of Viking
shall be entitled to rely thereon.

                    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 Viking Stock owned by Shareholder, including all Viking
         Stock as to which Shareholder has sole or shared voting or investment
         power and all rights and options to acquire Viking 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 Viking
         Stock or any rights, options or warrants to purchase Viking Stock, or
         any





                                       2.
<PAGE>   52
         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 including the combined
         financial results of Giga-tronics and Viking for a period of at least
         30 days of combined operations of Giga-tronics and Viking 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 Viking 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
         Viking Stock immediately prior to the Merger.  For purposes of the
         preceding sentence, shares of Viking 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 Viking
         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 Viking 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, Giga-tronics is under no obligation to register
the sale, transfer or other disposition of any





                                       3.

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.

                 5.       NOTICES.  Any notice or communication required or

                 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)     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
         financial results of Giga-tronics and Viking for a period of at least
         30 days of combined operations of Giga-tronics and Viking 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.

                          (d)     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 Viking 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
         Viking Stock immediately prior to the Merger.  For purposes of the
         preceding sentence, shares of Viking 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
