ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

        On December 2, 1997, Giga-tronics Incorporated, a California corporation
(the "Registrant") acquired Ultracision, Inc., a California corporation
("Ultracision"), by merging Giga Acquisition Inc., a wholly owned subsidiary of
the Registrant, with and into Ultracision with Ultracision as the surviving
corporation. By virtue of the merger, Ultracision became a direct, wholly-owned
subsidiary of the Registrant, and all of Ultracision's outstanding capital stock
was converted into capital stock of the Registrant as adjusted to reflect an
exchange ratio (the "Exchange Ratio") of approximately .75 shares of the
Registrant's common stock for each share of Ultracision common stock. As a
result, each shareholder of Ultracision became the owner of shares of capital
stock of the Registrant as adjusted to reflect the Exchange Ratio. Additionally,
each outstanding option to purchase shares of Ultracision common stock was
automatically converted into an option to purchase, upon the same terms and
conditions, shares of the Registrant's common stock in an amount adjusted to
reflect the Exchange Ratio.

                      AGREEMENT AND PLAN OF REORGANIZATION


        THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is entered
into as of the 26th day of November, 1997, by and among Giga-tronics
Incorporated, a California corporation ("Giga-tronics"), Giga Acquisition Corp.,
a Delaware corporation and a wholly owned subsidiary of Giga-tronics ("Merger
Sub"), and Ultracision, Inc., a California corporation ("Ultracision") and
Gordon Hampton, a shareholder of Ultracision (the "Shareholder").


                                    RECITALS

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

        B. The Board of Directors of Ultracision has approved, and has resolved
to recommend that the shareholders of Ultracision approve, the Merger and this
Agreement and the shareholders of Ultracision have approved 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
<PAGE>   3

                                    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 Ultracision (the "Merger"), as soon as practicable following the
satisfaction or waiver of the conditions set forth in Article VIII hereof.
Following the Merger, Ultracision 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, Ultracision 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
the General Corporation Law of California. 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 property, rights, privileges, powers and franchises and be
subject to all of the restrictions, liabilities and duties of Ultracision and
Merger Sub, all as provided under the laws of the State of California.

        (d) The closing of the transactions contemplated by this Agreement (the
"Closing") shall take place on December 2, 1997 at the offices of Gibson, Dunn &
Crutcher LLP, One Montgomery Street, San Francisco, California 94104, or at such
other date and place as Giga-tronics and Ultracision 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 Ultracision Common Stock issued and outstanding
immediately prior to the Effective Time (the "Ultracision 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 517,000 shares of Giga-tronics Common Stock (the "Merger
Consideration") will be issued in the Merger, including 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 Ultracision Shares into Giga-tronics
Common Stock and shall be equal to (a) 517,000 divided by (b) the number of
Ultracision Shares outstanding at the Effective Time 



                                       2
<PAGE>   4

(the "Ultracision Outstanding Equivalent Number"). All Ultracision 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 Ultracision 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) On the Closing Date, each holder of Ultracision Shares shall
surrender all of such holder's certificates which immediately prior to the
Effective Time represented issued and outstanding Ultracision Shares
(individually a "Certificate" and collectively the "Certificates") duly endorsed
for transfer. Upon such surrender Giga-tronics shall promptly deliver such
Merger Consideration that such holder is entitled to receive pursuant to Section
1.02(a) hereof to such surrendering holder. 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.

        (b) After the Effective Time there shall be no transfers on the stock
transfer books of either Ultracision (the stock transfer books of which shall be
closed) or the Surviving Corporation of Ultracision Shares which were
outstanding immediately prior to the Effective Time.

        Section 1.04. Intentionally Deleted.

        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 Ultracision 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
Ultracision 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 Giga-tronics
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 NASDAQ prior to the Effective Time.

        Section 1.06. Ultracision Options. Giga-tronics will assume the
outstanding Ultracision options for shares of Ultracision Common Stock
("Ultracision Options") set forth in the Disclosure Schedule, as adjusted to
reflect the Exchange Ratio. Each outstanding option to purchase shares of
Ultracision Common Stock (each, an "Option") issued pursuant to any of
Ultracision's stock option plans, whether vested or unvested, shall convert into
an option (a "Replacement Option") to acquire, on the same terms and conditions,
including the vesting schedule, as were applicable under such replaced Option
prior to the Effective Time, the number of shares of Giga-tronics Common Stock
(rounded down to the nearest whole number) equal to the product of the Exchange
Ratio and the number of shares subject to such Option, at a price per



                                       3
<PAGE>   5

share equal to the aggregate exercise price for the shares subject to such 
Option divided by the number of full shares of Giga-tronics Common Stock deemed
to be purchasable pursuant to such Replacement Option; provided, however, that
in no event shall the terms of any Replacement Option give the optionee
additional benefits that such optionee did not have under an original Option
that is described under Section 421(a) of the Code. Following the Effective
Time, upon surrender of the outstanding Options, Giga-tronics shall deliver to
holders of Options appropriate option agreements representing the Replacement
Options.

        Section 1.07. Registration of Giga-tronics Common Stock.

        (a) 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 1933, 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 Giga-tronics
               Incorporated that such registration is not required or unless
               sold pursuant to Rule 145 of such Act."

        (b) Simultaneous with the execution hereof, Giga-tronics and the
shareholders of Ultracision shall enter into an agreement with respect to the
registration of the shares of Giga-tronics Common Stock received in the Merger
in substantially the form attached hereto as Exhibit 1.07 (the "Registration
Rights Agreement").

                                   ARTICLE II
                            THE SURVIVING CORPORATION

        Section 2.01. Articles of Incorporation. The Articles 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 attached as Exhibit 2.02 hereto 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
Ultracision at the Effective Time shall become the initial officers of the
Surviving Corporation.

laws of the State of California, and has all corporate powers and all material

conducted. Each of Ultracision and its Subsidiaries (as defined in Section 3.06)
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.

Sections 5.09 and 6.08, respectively, hereof) and the consummation by
Ultracision of the transactions contemplated hereby and thereby are within
Ultracision's corporate powers and have been duly authorized by all necessary
corporate action. The Ultracision and Giga-tronics Affiliates Agreement are
collectively referred to herein as the "Ultracision Ancillary Agreements." This
Agreement and the Ultracision Ancillary Agreements constitute, or upon execution
will constitute, valid and binding agreements of Ultracision, enforceable
against Ultracision in accordance with their respective terms, subject to laws
of general applicability relating to bankruptcy, insolvency, reorganization,
moratorium, and the relief of debtors and rules governing specific performance,
injunctive relief or other equitable remedies.

        (b) The execution, delivery and performance by the Shareholder of this
Agreement, the Registration Rights Agreement, and the Ultracision Ancillary
Agreements and the consummation by the Shareholder of the transactions
contemplated hereby and thereby are within the Shareholder's powers. This
Agreement, the Registration Rights Agreement and the Ultracision Ancillary
Agreements constitute, or upon execution will constitute, valid and binding
agreements of the Shareholder, enforceable against the Shareholder in accordance
with their respective terms, subject to laws of general applicability relating
to bankruptcy, insolvency, reorganization, moratorium, the relief of debtors and
rules governing specific performance, injunctive relief or other equitable
remedies and the extent to which indemnification provisions in the Registration
Rights Agreement are limited by public policy.

heretofore operated.

        (b) The execution, delivery and performance by the Shareholder of this
Agreement, the Registration Rights Agreement, the Ultracision Ancillary
Agreements and the Agreement of Merger and the consummation of the Merger by the

on the part of Ultracision which 



                                       12

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

any mortgage, pledge, lien, charge, security interest, encumbrance, restriction,
lease, license, easement, liability or adverse claim of any nature whatsoever,
except (i) mortgages or security interests shown on the Balance Sheet as
securing specific liabilities or obligations or (ii) those imperfections of
title and encumbrances, if any, which, individually or in the aggregate, (A) are

of business. All of the properties and assets owned, leased or used by

a default, right to accelerate or loss of rights under, any terms or provisions
of its certificate of incorporation or by-laws as presently

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. The information with

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, the Merger will so qualify.

Disclosure Schedule sets forth all persons who, as of the date of this
Agreement, may be deemed to be affiliates of Ultracision under Rule 145 of the

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 Ultracision is a party or otherwise binding upon Ultracision which has or
could reasonably be expected to have the effect of prohibiting or impairing any

Ultracision has not entered into any agreement under which Ultracision is
restricted from selling, licensing or otherwise distributing any of its
products.

        Section 3.26. Interested Party Transactions. No officer, director or
shareholder of Ultracision (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 Ultracision furnishes or sells or proposes to
furnish or sell, or (ii) 



                                       15
<PAGE>   17

an economic interest in any entity that purchases from, or sells or furnishes
to, Ultracision any goods 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.

not incur any indebtedness or liabilities of any kind except pursuant to this
Agreement.

        Section 6.08. Compliance with the Securities Act. Giga-tronics shall
cause each person who is an "affiliate," as that term is used in paragraphs (c)

attached hereto as Exhibit 6.08 (a "Giga-tronics Affiliates Agreement").

                                   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.

        Section 7.04. Certain Filings.  The Parties shall cooperate with one 
another:

        (a) in determining whether any action by or in respect of, or filing
with, any governmental body, agency or official, or authority is required, or
any actions, consents, approvals or waivers are required to be obtained from
parties to any material contracts, in connection with the consummation of the
transactions contemplated by this Agreement; and

        (b) 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 Ultracision and
Giga-tronics as to the content thereof, which approval shall not be unreasonably
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
consummated, and, without limiting the generality of the foregoing, to obtain
all consents and authorizations of third parties and to make all filings with,
and give all notices to, third parties that may be necessary or reasonably
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 Ultracision and the Shareholder 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 except for changes contemplated by this Agreement) and
Ultracision shall have provided Giga-tronics with a certificate executed by the
President and the Chief Financial Officer of Ultracision, 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 



                                       27
<PAGE>   29

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

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

               (c) No Material Adverse Change. There shall have been no Material
Adverse Change in Ultracision since the Ultracision 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 Ultracision 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' due diligence review of the business, operations and financial
condition of Ultracision shall not have revealed any facts or circumstances
which in the reasonable judgment of Giga-tronics could have a Material Adverse
Effect on Ultracision. If such due diligence review shall reveal facts or
circumstances which in the reasonable judgment of Giga-tronics could have a
Material Adverse Effect on Ultracision, Giga-tronics shall promptly notify
Ultracision 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 Ultracision 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 Ultracision. Ultracision'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 Ultracision, but only in a writing signed by
Ultracision):

               (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 



                                       28
<PAGE>   30

Ultracision 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 Articles VI and VII in all material
respects on or before the Effective Date, and Ultracision shall receive a
certificate to such effect signed by Giga-tronics' 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 Ultracision 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) 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).

               (b) 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 Ultracision 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 Ultracision or Giga-tronics.

               (c) 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, Ultracision or the Surviving Corporation or would be reasonably
likely to subject any of Giga-tronics, Merger Sub, Ultracision or any of their
respective directors or officers to substantial penalties or criminal liability.

                            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 Ultracision or Giga-tronics:

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

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

               (c) by either Giga-tronics and Merger Sub or Ultracision,
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 Ultracision 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

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

               (f) by Giga-tronics, if Ultracision shall have issued any
Ultracision 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 Ultracision,
respectively, at any time after December 10, 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
Ultracision, except that each of the agreements contained or referred to in
Sections 5.08, 6.06 and 10.02 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.

                                    ARTICLE X

transactions contemplated hereby. Any other costs and expenses not specifically
identified as applicable to either Ultracision or Giga-tronics shall be shared

Agreement may be amended, and the observance of any term of this Agreement may
be waived (either generally or in a particular instance and either retroactively
or prospectively) only by a writing signed by the party to be bound thereby. The

               Giga-tronics Finalizes Acquisition of Ultracision

San Ramon, California - Giga-tronics Incorporated (NASDAQ-GIGA) announced today
that it had completed its acquisition of Ultracision, Inc. of Santa Clara,
California effective December 2, 1997. 517,000 shares of Giga-tronics stock
were exchanged for all of the outstanding shares of Ultracision stock, a
transaction that is intended to be accounted for using the "pooling of
interests" method of accounting.

     Ultracision serves the semiconductor industry as a developer and a
manufacturer of robotic equipment for the handling and inspection of silicon
wafers and hard drive media. The company additionally produces a line of
probers for the testing and inspection of silicon devices. Sales, as reported
for the fiscal year ended March 31, 1997, were $5,653,000.

     Ultracision will function as a wholly owned subsidiary of Giga-tronics.
Its present management, including Gordon Hampton as President, will remain in
place.

     This is Giga-tronics second strategic move into the semiconductor
equipment market, following the acquisition of Viking Semiconductor Equipment,
Inc. last June.

     Giga-tronics designs, manufactures and markets an extensive line of
instruments and automatic test systems with broad application in wireless
communications, including cellular telephone, satellite transmission, aircraft
navigation, and electronic defense.

     Headquartered in San Ramon, California, Giga-tronics is a publicly held
company, traded over the counter on NASDAQ National Market Systems under the
symbol "GIGA".
