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. 7 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. 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. 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. 10 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. 5. 11 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 Articles 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 Viking at the Effective Time shall become the initial officers of the Surviving Corporation. ARTICLE III REPRESENTATIONS AND WARRANTIES OF VIKING Except as disclosed in a document referring specifically to this Agreement (the "Viking Disclosure Schedule") which is delivered by Viking 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), Viking represents and warrants to Giga-tronics as set forth below: SECTION 3.01 CORPORATE EXISTENCE AND POWER.

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

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 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.

(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. 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.
