                      AGREEMENT AND PLAN OF REORGANIZATION


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


                                    RECITALS

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

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

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

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

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



                                       1.






                                    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 ASCOR (the "Merger"),  as soon as practicable following the
satisfaction  or  waiver  of the  conditions  set forth in  Article  VI  hereof.
Following the Merger,  ASCOR shall  continue as the surviving  corporation  (the
"Surviving  Corporation"),  and the separate  corporate  existence of Merger Sub
shall cease.

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

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

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

         SECTION 1.02         CONVERSION OF SHARES.

                      (a)     At the Effective Time:

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

                                       2.
 





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

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

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


         SECTION 1.03         EXCHANGE OF CERTIFICATES.

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

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

                                       3.






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

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

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

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

                                       4.







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

         SECTION 1.06         ASCOR STOCK OPTIONS AND WARRANTS.

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

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

                                       5.






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

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

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

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


                                   ARTICLE II

                            THE SURVIVING CORPORATION

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

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

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


                                       6.







                                   ARTICLE III

                     REPRESENTATIONS AND WARRANTIES OF ASCOR

         Except  as  disclosed  in a  document  referring  specifically  to this
Agreement  (the "ASCOR  Disclosure  Schedule")  which is  delivered  by ASCOR to
Giga-tronics  no less than five days prior to the  execution  of this  Agreement
(which shall contain  appropriate  and  reasonably  detailed  references to each
representation and warranty to which any item there disclosed  pertains),  ASCOR
represents and warrants to Giga-tronics as set forth below:

         SECTION 3.01 CORPORATE EXISTENCE AND POWER. ASCOR is a corporation duly
incorporated,  validly existing and in good standing under the laws of the State
of  California,  and has all  corporate  powers  and all  material  governmental
licenses,  authorizations,  consents and approvals (collectively,  "Governmental
Authorizations")  required to carry on its business as now  conducted.  ASCOR is
duly qualified to do business as a foreign  corporation  and is in good standing
in each  jurisdiction  where the character of the property owned or leased by it
or the nature of its activities makes such  qualification  necessary.  ASCOR has
delivered  to  Giga-tronics  true and  complete  copies of ASCOR's  Articles  of
Incorporation and Bylaws as currently in effect.

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

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

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

                      (b)  compliance  with any applicable  requirements  of the

                                       7.







                      (d)  compliance  with  any  applicable  foreign  or  state
securities or "blue sky" laws; and

                      (e)  such  other   filings  or   registrations   with,  or
authorizations,   consents  or  approvals  of,  governmental  bodies,  agencies,
officials  or  authorities,  the  failure  of which to make or obtain  would not
materially adversely affect the ability of ASCOR,  Giga-tronics or Merger Sub to
consummate the transactions  contemplated hereby and operate their businesses as
heretofore operated.

         SECTION 3.04 NON-CONTRAVENTION. The execution, delivery and performance
by ASCOR of this Agreement,  the ASCOR Ancillary  Agreements and the Certificate
of Merger and the consummation by ASCOR of the transactions  contemplated hereby
and thereby do not and will not:

                      (a)   contravene   or  conflict   with  the   Articles  of
Incorporation or Bylaws of ASCOR;

                      (b) assuming  compliance  with the matters  referred to in
Section 3.03 and assuming the requisite approval of ASCOR's  shareholders of the
Merger,  contravene  or conflict with or constitute a violation of any provision
of any law, regulation,  judgment,  injunction,  order or decree binding upon or
applicable to ASCOR;

                      (c) conflict  with or result in a breach or violation  of,
or constitute a default under, or result in the termination or cancellation  of,
or right to accelerate, any agreement, contract or other instrument binding upon
ASCOR or any license,  franchise,  permit or other similar authorization held by
ASCOR; or

                      (d) result in the creation or  imposition  of any Lien (as

                      (d) No ASCOR Options for the purchase of any ASCOR Shares;
and

                      5,119,395  shares  of  ASCOR  Common  Stock  reserved  for
issuance upon exercise of  outstanding  ASCOR  Warrants and ASCOR  Options.  All
outstanding ASCOR Common Shares have been duly authorized and validly issued and

are no  outstanding  obligations  of ASCOR to  repurchase,  redeem or  otherwise
acquire any ASCOR Securities.  No holder of ASCOR Securities has, as of the date
hereof, any contractual right to include any such securities in any registration

         SECTION 3.06 SUBSIDIARIES AND INVESTMENTS. ASCOR does not own, directly
or  indirectly,  any  outstanding  capital  stock  or  equity  interest  in  any

Section of this  Agreement) of financial  statements  (hereinafter  collectively
called the "Financial Statements"),  all of which are complete and correct, have
been  prepared in  accordance  with  generally  accepted  accounting  principles
consistently applied and maintained  throughout the periods indicated and fairly
present the financial  condition of ASCOR as at their  respective  dates and the

         SECTION 3.09 NO  UNDISCLOSED  LIABILITIES.  There are no liabilities of
ASCOR or any of its Subsidiaries,  including contingent liabilities, of the type

                      (d)     liabilities under this Agreement.

including,  without limitation, any claims for indemnification arising under any
agreement  to which  ASCOR  is a  party,  which  could,  individually  or in the
aggregate,  have a  Material  Adverse  Effect  on ASCOR  or which in any  manner
challenges or seeks to prevent,  enjoin,  alter or  materially  delay any of the
transactions  contemplated  hereby.  ASCOR is not subject to or in default  with
respect to any writ, order,  judgment,  injunction or decree, which would have a
Material Adverse Effect on ASCOR.

         SECTION 3.11         TAXES.

                      (a) For purposes of this Agreement, "Tax" or "Taxes" means
any and all taxes, fees, levies, duties, tariffs,  imposts, and other charges of
any kind  (together with any and all interest,  penalties,  additions to tax and
additional  amounts imposed with respect thereto) imposed by any governmental or
taxing authority  including,  without  limitation:  taxes or other charges on or

charges in the nature of excise, withholding, ad valorem, stamp, transfer, value
added,  or gains  taxes;  license,  registration  and  documentation  fees;  and
customs' duties, tariffs, and similar charges.

                      (b)  Except as  described  in  Schedule  3.11 of the ASCOR
Disclosure Schedule,  (i) ASCOR has filed all federal,  state, local and foreign
tax returns and reports  required to be filed by it and has paid and  discharged
all Taxes  shown as due thereon and has paid all of such other Taxes as are due,
other than (a) such filings, payments or other occurrences that would not have a
Material Adverse Effect;  (ii) neither the IRS nor any other taxing authority or

after due inquiry,  threatening  to assert against ASCOR any deficiency or claim
for additional Taxes or interest  thereon or penalties in connection  therewith;
(iii)  ASCOR has not  granted  any  waiver of any  statute of  limitations  with
respect to, or any  extension  of a period for the  assessment  of, any federal,

other party is in default  under any Material  ASCOR  Agreement and no event has
occurred  which (after notice or lapse of time or both) would become a breach or
default  under,  or would permit  modification,  cancellation,  acceleration  or
termination  of any  Material  ASCOR  Agreement or result in the creation of any
security  interest  upon,  or any person  obtaining  any right to  acquire,  any
properties, assets or rights of ASCOR.

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

misleading.  The Proxy Statement will comply as to form in all material respects
with  the  provisions  of  the  Exchange  Act  and  the  rules  and  regulations
thereunder,  except  that no  representation  is made by ASCOR  with  respect to
information supplied by Giga-tronics or Merger Sub for inclusion therein.

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

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.

licensors and others having business  relationships with it that are material to
its  business  in  substantially  the same  manner  as it has  prior to the date
hereof.  If ASCOR becomes aware of a material  deterioration  or facts which are
likely  to result  in a  material  deterioration  in the  relationship  with any
material customer,  supplier,  licensor or others having business  relationships
with it,  it will  promptly  bring  such  information  to the  attention  of the
Giga-tronics in writing.

industry.

         SECTION 5.09  COMPLIANCE  WITH THE SECURITIES ACT. ASCOR shall prior to
15 days after  signing but in any event prior to mailing of the Proxy  Statement

                                   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  connection  with  the  preparation  of  the  Proxy
Statement;

                      (b) in  connection  with  the  preparation  of any  filing
required by the HSR Act;

                      (c) 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

                                       29.







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

                                       30.






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

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

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

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

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

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

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

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

         SECTION 8.02  CONDITIONS TO OBLIGATIONS OF ASCOR.  ASCOR's  obligations
hereunder  are  subject to the  fulfillment  or  satisfaction,  on and as of the
Effective Date, of

                                       31.






each of the  following  conditions  (any one or more of which  may be  waived by
ASCOR, but only in a writing signed by ASCOR):

                      (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  ASCOR  with a  certificate  executed  by the  President  and the Chief
Financial  Officer of  Giga-tronics,  dated as of the  Effective  Date,  to such
effect; provided,  however, that any inaccuracy of a representation or warranty,
on  the  date  hereof  or on  the  Effective  Date,  shall  not  result  in  the
non-satisfaction   of  this  Section  8.02(a)  unless  any  such  inaccuracy  or
inaccuracies,  either (i) individually or in the aggregate, represent a Material
Adverse   Effect  on   Giga-tronics   or  (ii)  are  willful   and   intentional
misrepresentations that constitute common law fraud of a material matter.

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

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

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

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

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

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

                                       32.






agreeing to use its  reasonable  best efforts to have any such order,  decree or
injunction lifted).

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

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

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


                                   ARTICLE IX

                            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

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

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

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

                                       (A) withdrawn its  recommendation  of the
         Merger, or


                                       33.






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

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

                                       (A) withdrawn its  recommendation  of the
         Merger, or

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

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

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

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

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

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

Agreement and the  provisions  hereof shall be binding upon each of the parties,
their  permitted  successors and assigns.  This Agreement may not be assigned by
any party without the prior consent of the other.

                                       36.







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

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

         SECTION 11.09 OTHER REMEDIES.  Except as otherwise provided herein, any
and all  remedies  herein  expressly  conferred  upon a party  shall  be  deemed
cumulative with and not exclusive of any other remedy conferred hereby or by law
on such  party,  and the  exercise  of any one  remedy  shall not  preclude  the
exercise of any other.

         SECTION  11.10  AMENDMENT  AND  WAIVERS.  Any term or provision of this
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
waiver by a party of any  breach  hereof or default  in the  performance  hereof
shall  not be  deemed  to  constitute  a  waiver  of any  other  default  or any
succeeding  breach or  default.  At any time  before or after  approval  of this
Agreement and the Merger by the shareholders of ASCOR and prior to the Effective
Time,  this Agreement may be amended or  supplemented  by ASCOR or  Giga-tronics
with  respect  to any of the terms  contained  in this  Agreement,  except  that
following  approval by the  shareholders of ASCOR there shall be no amendment or
change to the  provisions  hereof with  respect to the  Exchange  Ratio  without
further  approval by the  shareholders of ASCOR, and no other amendment shall be
made which by law requires  further approval by such  shareholders  without such
further approval.

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

         SECTION 11.12 CONSTRUCTION OF AGREEMENT;  KNOWLEDGE.  A reference to an
Article,  Section or an  Exhibit  shall  mean an  Article  of, a Section  in, or
Exhibit to, this Agreement unless otherwise explicitly set forth. The titles and
headings  herein  are for  reference  purposes  only and shall not in any manner
limit the  construction  of this Agreement which shall be considered as a whole.
The words "include," "includes" and "including" when used herein shall be deemed
in each case to be followed by the words "without  limitation."  For purposes of
this  Agreement,  "knowledge"  of any  party  shall  mean the  knowledge  of the
executive  officers of such party after such  officers  shall have made  inquiry
that is customary and appropriate  under the circumstances to which reference is
made.


                                       37.






         SECTION  11.13  COUNTERPARTS.  This  Agreement  may be  executed in any
number of counterparts,  each of which shall be an original as against any party
whose signature  appears thereon and all of which together shall  constitute one
and the same  instrument.  This Agreement  shall become binding when one or more
counterparts hereof,  individually or taken together,  shall bear the signatures
of all of the paries reflected hereon as signatories.

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