Second Amended and Restated Warrant between the Company and SVB Financial Group dated March 26, 2018

Exhibit 10.4

SECOND AMENDED AND RESTATED WARRANT

THIS SECOND AMENDED AND RESTATED WARRANT ("WARRANT") WAS ORIGINALLY SOLD ON THE ISSUE DATE IN A PRIVATE TRANSACTION AND IS AMENDED AND RESTATED AS OF THE SECOND RESTATEMENT DATE, WITHOUT REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR THE SECURITIES LAWS OF ANY STATE, AND MAY BE OFFERED OR SOLD ONLY IF REGISTERED UNDER THE SECURITIES ACT AND SUCH LAWS OR IF AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT AND SUCH LAWS IS AVAILABLE.

The term “Holder” shall initially refer to SVB Financial Group (by assignment on the Issue Date from its Affiliate, Silicon Valley Bank, a California corporation), which is the initial holder of this Warrant and shall further refer to any subsequent permitted holder of this Warrant from time to time.

Giga-tronics Incorporated, a California corporation (the “Company”) does hereby certify and agree that for good and valuable consideration, Holder, or its permitted successors and assigns, hereby is entitled to Exercise or Exchange this Warrant (each as defined below) in the Company for up to Ninety-One Thousand Five Hundred Twenty (91,520) duly authorized, validly issued, fully paid and non-assessable shares of its Common Stock, no par value per share (the “Common Stock”) upon the terms and subject to the provisions of this Warrant. The Common Stock issuable upon Exercise or Exchange of this Warrant is referred to herein as the “Warrant Stock”. Capitalized terms used but not defined in this Warrant have their meanings as set forth in that certain Loan and Security Agreement of even date herewith between the Company and Partners for Growth IV, L.P. (the “Loan Agreement”), regardless of whether the Loan Agreement is then in effect. When the term “convert” or “conversion” in relation to the Warrant is used herein, it includes an Exchange and an Exercise, each as defined below, as applicable.

1.1     Term of Warrant. This Warrant shall be convertible from the Issue Date until the Expiration Date.

1.2     Exchange Price. The price per share at which the Warrant Stock is issuable upon conversion of this Warrant shall be the lesser of (i) $0.25 per share and (ii) the exercise price per share under those certain common stock warrants issued to investors as part of Units on or about January 29, 2016, as such exercise price is restated by agreement of the Company and such investors on or about the 2^nd Restatement Date of this Warrant (the “Exchange Price”).

1.3     Exercise of Warrant; Exchange of Warrant.

(a)     This Warrant may be Exercised (as defined below) in whole or in part, upon surrender of this Warrant to the Company at its then principal offices in the United States, together with the form of election to Exchange or Exercise attached hereto as Exhibit A (the “Election”) duly completed and executed with “Exercise” selected as the mode of conversion, and upon payment to the Company of the Exchange Price for the number of shares of Warrant Stock in respect of which this Warrant is then being converted (an “Exercise”). In lieu of an Exercise, Holder may exchange this Warrant in whole or in part on a cashless basis by indicating so in the Election and proceeding in accordance with the remainder of this Section 1.3 (an “Exchange”).

(b)     Upon an Exchange, the Holder shall receive Warrant Stock such that, without the payment of any funds, the Holder shall surrender this Warrant in exchange for the number of shares of Warrant Stock equal to “X” (as defined below), computed using the following formula:

Where

(c)     For purposes of this Warrant, the “Fair Market Value” of one share of Warrant Stock shall be (i) if the Company’s Common Stock is becomes listed on a national stock exchange, the volume weighted average price per share reported on such exchange over the 30 trading-day period prior to the date Holder delivers its Election to the Company (the “30 Day VWAP”), or (ii) if the Common Stock is traded over-the-counter, the average of the bid and ask price for Common Stock over the 30 trading-day period prior to the date Holder delivers its Election to the Company. If another class or series of Company securities is listed or traded as aforesaid, the Fair Market Value shall be adjusted based on the ratio that the Warrant Stock converts into such other class or series or such other class or series converts into Warrant Stock, as appropriate. If the Common Stock is not traded as contemplated in clauses (i) or (ii), above, the Fair Market Value of the Company’s Warrant Stock shall be the price per share of Warrant Stock which the Company could obtain from a willing buyer of Warrant Stock sold by the Company from its authorized but unissued shares, initially as the Board of Directors of the Company (“Board”) shall determine in its reasonable good faith judgment, but in no event less than the price per share at which Common Stock (or options for Common Stock) are then issuable to Company employees based on a valuation compliant with Section 409A of the United States Internal Revenue Code; provided, however, if Holder disagrees the Fair Market Value of Warrant Stock as determined by the Board, the parties shall jointly engage a valuation expert to value the Warrant Stock based on a valuation of the Company as a going concern using standard valuation methodologies for the Warrant Stock. If the Warrant is to be converted in connection with an Acquisition, the Fair Market Value of a share of Warrant Stock shall be based on the enterprise value specified or implied in such Acquisition and shall be the greater of (A) the value attributable to the Warrant Stock and (B) the value attributable to the Company securities into which the Warrant Stock is (or may be) convertible (but subject to Holder’s conversion directly into such other Company securities).

(d)     Upon surrender of this Warrant, and the duly completed and executed Election, and payment of the Exchange Price (if an Exercise) or conversion of this Warrant through Exchange, the Company shall promptly issue and deliver to the Holder or such other person as the Holder may designate in writing a certificate or certificates for the number of shares of Warrant Stock issuable pursuant to the terms of this Warrant upon conversion. Such certificate or certificates shall be deemed to have been issued and any person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Stock as of the date of the surrender of this Warrant, and the duly completed and executed Election, and payment of the Exchange Price in the case of an Exercise or conversion of this Warrant through Exchange; provided, that if the date of surrender of this Warrant and payment of the Exchange Price is not a business day, the certificates for the Warrant Stock shall be deemed to have been issued as of the next business day (whether before or after the Expiration Date). If this Warrant is converted in part, a new warrant of the same tenor and for the number of shares of Warrant Stock not converted shall be executed by the Company and delivered to Holder.

1.4     Fractional Interests. The Company shall not be required to issue fractions of shares of Warrant Stock upon the conversion of this Warrant. If any fraction of a share of Warrant Stock would be issuable upon the exchange of this Warrant (or any portion thereof), the Company shall purchase such fraction for an amount in cash equal to the Fair Market Value of the Warrant Stock.

1.5     Automatic Exchange on Expiration Date. In the event that, by the Expiration Date, this Warrant has not been fully converted, then this Warrant shall be deemed Exchanged pursuant to Section 1.3 as to all Warrant Stock (or such other securities) for which it shall not previously have been converted, and the Company shall promptly deliver a certificate representing the Warrant Stock (or such other securities) issued upon such conversion to the Holder.

1.6     Treatment of Warrant Upon Acquisition of Company.

(a)     “Acquisition”. For the purpose of this Warrant, “Acquisition” means any sale or other disposition of all or substantially all of the assets of the Company in whatever form, or any reorganization, consolidation, or merger of the Company (whether in a single transaction or multiple related transactions) where the holders of the Company’s securities before the transaction beneficially own less than 50% of the outstanding voting securities of the surviving entity after the transaction(s).

(b)     Treatment of Warrant at Acquisition. Upon the closing of any Acquisition, at Holder’s option: (i) if the surviving entity (if applicable in such Acquisition) is willing assume the obligations of the Company under this Warrant, then if Holder so elects this Warrant shall be convertible into the same securities as would be payable for the Warrant Stock issuable upon conversion of the unconverted portion of this Warrant as if such Warrant Stock were outstanding on the record date for the Acquisition (and the Warrant Price and/or number of shares of Warrant Stock shall be adjusted accordingly); or (ii) the Company or other surviving entity in such Acquisition may (in lieu of assuming this Warrant under clause (i)) upon initial closing of such Acquisition purchase this Warrant at its “Fair Value” (the “Purchase Price”). For purposes hereof, “Fair Value” means that value determined by the parties using a Black-Scholes Option-Pricing Model (the “ Black-Scholes Calculation”) with the following assumptions: (A) a risk-free interest rate equal to the risk-free interest rate at the time of the closing of the Acquisition (or as close thereto as practicable), (B) a contractual life of the Warrant equal to the remaining term of this Warrant as of the date of the announcement of the Acquisition, (C) an annual dividend yield equal to dividends declared on the underlying Warrant Stock (including securities into which the Warrant Stock may be convertible) during the term of this Warrant (calculated on an annual basis), and (D) a volatility factor of the expected market price of the Company’s Common Stock comprised of: (1) if the Company is publicly traded on a national securities exchange, its volatility over the one year period ending on the day prior to the announcement of the Acquisition, (2) if the Common Stock is traded over-the-counter, its volatility over the one year period ending on the day prior to the announcement of the Acquisition, or (3) if the Company is a non-public company, the volatility, over the one year period prior to the Acquisition, of an average of publicly-traded companies in the same or similar industry to the Company with such companies having similar revenues. The Purchase Price determined in accordance with the above shall be paid upon the initial closing of the Acquisition and shall not be subject to any post-Acquisition closing contingencies or adjustments; provided, however, the parties may take such post-Acquisition closing contingencies or adjustments into account in determining the Purchase Price, and if the parties take any post-Acquisition closing contingencies or adjustments into account, then upon the partial or complete removal of those post-Acquisition closing contingencies or adjustments, a new Black-Scholes Calculation would be made using all of the same inputs except for the value of the Company’s Common Stock (as determined under subclause (D)), and any increase in Fair Value (and, correspondingly, Purchase Price), including, without limitation, as a result of any earn-out or escrowed consideration, would be paid in full to Holder immediately after those post-Acquisition closing contingencies or adjustments can be determined or achieved.

(a)     This Warrant may be transferred, in whole or in part, without restriction, subject to (i) Holder’s compliance with applicable securities laws (including, without limitation, the delivery of investment representation letters and legal opinions in legally sufficient and customary form), and (ii) the transferee holder of the new Warrant assuming in writing the obligations of the Holder and making the representations and warranties set forth in this Warrant. Notwithstanding and without the necessity of delivering an opinion of counsel, Holder may at any time transfer this Warrant in whole or in part to any affiliate. By its acceptance of this Warrant, each such affiliate transferee will be deemed to have made to the Company each of the representations and warranties set forth in Section 7 hereof and agrees to be bound by all of the terms and conditions of this Warrant as if the original Holder hereof. A transfer may be registered with the Company by submission to it of this Warrant, together with the Assignment Form attached hereto as Exhibit B duly completed and executed. After the Company’s receipt of this Warrant and the Assignment Form so completed and executed, the Company will issue and deliver to the transferee a new warrant (representing the portion of this Warrant so transferred) at the same Exchange Price per share and otherwise having the same terms and provisions as this Warrant, which the Company will register in the new holder’s name. In the event of a partial transfer of this Warrant, the Company shall concurrently issue and deliver to the transferring holder a new warrant that entitles the transferring holder to purchase the balance of this Warrant not so transferred and that otherwise is upon the same terms and conditions as this Warrant. Upon the due delivery of this Warrant for transfer, the transferee holder shall be deemed for all purposes to have become the holder of the new warrant issued for the portion of this Warrant so transferred, effective immediately prior to the close of business on the date of such delivery, irrespective of the date of actual delivery of the new warrant representing the portion of this Warrant so transferred. Notwithstanding any contrary provision herein, at all times prior to the IPO, Holder may not, without the Company’s prior written consent, transfer this Warrant or any portion hereof, or any shares issued upon any exercise hereof to any person or entity who directly competes with the Company, except in connection with an Acquisition of the Company by such a direct competitor.

(b)     In the event of the loss, theft or destruction of this Warrant, the Company shall execute and deliver an identical new warrant to the Holder in substitution therefor upon the Company’s receipt of (i) evidence reasonably satisfactory to the Company of such event and (ii) if requested by the Company, an indemnity agreement reasonably satisfactory in form and substance to the Company. In the event of the mutilation of or other damage to the Warrant, the Company shall execute and deliver an identical new warrant to the Holder in substitution therefor upon the Company’s receipt of the mutilated or damaged warrant.

(c)     The Company shall pay all reasonable costs and expenses incurred in connection with any conversion (by Exercise or Exchange), transfer or replacement of this Warrant, including, without limitation, the costs of preparation, execution and delivery of a new warrant and of share certificates representing all Warrant Stock.

(a)     The Company shall at all times reserve for issuance and keep available out of its authorized and unissued Common Stock, solely for the purpose of providing for the exchange of this Warrant, such number of shares of Common Stock as shall from time to time be sufficient therefor.

(b)     The Company will not, by amendment or restatement of its Certificate of Incorporation or Bylaws or through reorganization, consolidation, merger, amalgamation, sale of assets or otherwise, avoid or seek to avoid the observance or performance of any of the terms of this Warrant. Without limiting the foregoing, the Company will not increase the par value of any Warrant Stock receivable upon the exchange of this Warrant above the amount payable therefor upon such exchange.

(c)     So long as Holder holds this Warrant, the Company shall deliver to Holder such reports as it provides to its common stockholders generally, as and when delivered to such stockholders. Notwithstanding the foregoing, the Company shall provide Holder quarterly and annual financial statements upon request, if such statements are not publicly available. The parties shall not treat the Warrant or the Warrant Stock as being granted or issued as property transferred in connection with the performance of services or otherwise as compensation for services rendered.

4.1     Adjustments. The Exchange Price shall be subject to adjustment from time to time in accordance with this Section 4. Upon each adjustment of the Exchange Price pursuant to this Section 4, the Holder shall thereafter be entitled to acquire upon conversion, at the Exchange Price resulting from such adjustment, the number of shares of Warrant Stock obtainable by multiplying the Exchange Price in effect immediately prior to such adjustment by the number of shares of Warrant Stock acquirable immediately prior to such adjustment and dividing the product thereof by the new Exchange Price resulting from such adjustment.

4.2     Subdivisions, Combinations and Stock Dividends. If the Company shall at any time subdivide by split-up or otherwise, its outstanding Common Stock into a greater number of shares, or issue additional Common Stock as a dividend or otherwise with respect to any Common Stock, the Exchange Price in effect immediately prior to such subdivision or share dividend shall be proportionately reduced and the number of shares acquirable upon Exercise or Exchange hereunder shall be proportionately increased. Conversely, in case the outstanding Common Stock of the Company shall be combined into a smaller number of shares, the Exchange Price in effect immediately prior to such combination shall be proportionately increased and the number of shares acquirable upon Exercise or Exchange hereunder shall be proportionately reduced.

4.3     Reclassification, Exchange, Substitutions, Etc. Upon any reclassification, exchange, substitution, or other event that results in a change of the number and/or class of the securities issuable upon conversion of this Warrant, Holder shall be entitled to receive and the Company shall promptly issue an amended warrant for the number and kind of securities and property that Holder would have received for the Warrant Stock if this Warrant had been converted immediately before such reclassification, exchange, substitution, or other event. The amendment to this Warrant shall provide for adjustments (as determined in good faith by the Board) which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 4.3, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon conversion of the new Warrant. The provisions of this Section 4.3 shall similarly apply to successive reclassifications, exchanges, substitutions, or other similar events.

4.4.     Notices of Record Date, Etc. In the event that the Company shall:

(1) declare any dividend upon its Common Stock, whether payable in cash, property, stock or other securities and whether or not a regular cash dividend, or

(2) offer for sale to (but not necessarily exclusively to) its existing securityholders any additional shares of any class or series of the Company’s stock or securities exchangeable for or convertible into such stock in any transaction that would give rise (regardless of waivers thereof) to pre-emptive rights of any class or series of stockholders, or

(3) effect or approve (by stockholder vote or otherwise) any reclassification, exchange, substitution or recapitalization of the capital stock of the Company, including any subdivision or combination of its outstanding capital stock, or consolidation or merger of the Company with, or sale of all or substantially all of its assets to, another corporation, or to liquidate, dissolve or wind up (including an assignment for the benefit of creditors), or

(4) offer holders of registration rights the opportunity to participate in any public offering of the Company’s securities,

then, in connection with such event, the Company shall give to Holder:

(i) at least ten (10) days prior written notice of the date on which the books of the Company shall close or a record shall be taken for such a dividend or offer in respect of the matters referred to in (1) or (2) above;

(ii) in the case of the matters referred to in (3) above, at least ten (10) days prior written notice of the date when the same shall take place; and

(iii) in the case of the matter referred to in (4) above, the same notice as is given or required to be given to the holders of such registration rights.

Such notice in accordance with the foregoing clause (1) shall also specify, in the case of any such dividend, the date on which the holders of capital stock shall be entitled thereto and the terms of such dividend, and such notice in accordance with clause (2) shall also specify the date on which the holders of capital stock shall be entitled to exchange their capital stock for securities or other property deliverable upon such reorganization, reclassification, exchange, substitution, consolidation, merger or sale, as the case may be, and the terms of such exchange. Each such written notice shall be given by first class mail, postage prepaid, addressed to the holder of this Warrant at the address of Holder.

4.5     Adjustment by Board. If any event occurs as to which, in the opinion of the Board, the provisions of this Section 4 are not strictly applicable or if strictly applicable would not fairly protect the rights of the Holder in accordance with the essential intent and principles of such provisions, then the Board shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to protect such rights, but in no event shall any adjustment have the effect of increasing the Exchange Price as otherwise determined pursuant to any of the provisions of this Section 4, except in the case of a combination of shares of a type contemplated in Section 4.2 and then in no event to an amount larger than the Exchange Price as adjusted pursuant to Section 4.2.

4.6     Officers’ Statement as to Adjustments. Whenever the Exchange Price and/or number of shares of Warrant Stock subject to the Warrant is required to be adjusted as provided in this Section 4, the Company shall forthwith file at its principal office with a copy to the Holder notice parties set forth in Section 9 hereof a statement, signed by the Chief Executive Officer or Chief Financial Officer of the Company, showing in reasonable detail the facts requiring such adjustment, the Exchange Price and number of issuable shares that will be effective after such adjustment; provided, however, such statement shall not be required to the extent the information otherwise required by this Section 4.7 is available through the Company’s current reports filed with the Securities and Exchange Commission.

4.7     Issue of Securities other than Common Stock. In the event that at any time, as a result of any adjustment made pursuant to this Section 4, Holder thereafter shall become entitled to receive any securities of the Company, other than Common Stock, the number of such other shares so receivable upon Exercise or Exchange of this Warrant shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Stock contained in this Section 4.

Except as otherwise specified in this Warrant, this Warrant shall not entitle the Holder to any rights of a holder of Common Stock in the Company until such time as this Warrant is exchanged or exercised.

6.1      Corporate Power; Authorization. The Company has all requisite corporate power and has taken all requisite corporate action to execute and deliver this Warrant, to sell and issue the Warrant and Warrant Stock and to carry out and perform all of its obligations hereunder.

6.5     Governmental and other Consents. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any governmental authority or other person or entity is required on the part of the Company in connection with the issuance, sale and delivery of the Warrant and the Warrant Stock, except such filings pursuant to the United States Securities Act of 1933, as amended (the “Securities Act”) and applicable state securities laws, which have been made or will be made in a timely manner.

6.11     Legends. The Company shall remove any restrictive securities legends on Warrant Stock resulting from conversion of this Warrant as soon as permitted by applicable law.

Section 7.         Representations and Warranties of Holder. Holder hereby represents and warrants to the Company as of the Closing Date as follows:

7.1     Investment Experience. Holder is an “accredited investor” within the meaning of Rule 501 under the Securities Act, and was not organized for the specific purpose of acquiring the Securities. Holder is aware of the Company’s business affairs and financial condition and has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and its underlying securities. Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to Holder or to which Holder has access. Holder has such business and financial experience as is required to give it the capacity to protect its own interests in connection with the purchase of the Securities.

7.2     Investment Intent. Holder is purchasing the Warrant for investment for its own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act. Holder understands that the Warrant has not been registered under the Securities Act or registered or qualified under any state securities law in reliance on specific exemptions therefrom, which exemptions may depend upon, among other things, the bona fide nature of Holder's investment intent as expressed herein.

7.3     Authorization. Holder has all requisite power and has taken all requisite action required of it to carry out and perform all of its obligations hereunder. The execution and delivery of this Warrant has been duly authorized, executed and delivered on behalf of Holder and constitutes the valid and binding agreement of Holder, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization or similar laws relating to or affecting the enforcement of creditors' rights generally and (ii) as limited by equitable principles generally. The consummation of the transactions contemplated herein and the fulfillment of the terms herein will not result in a breach of any of the terms or provisions of Holder's constitutional documents or instruments.

7.4     The Act. Holder understands that this Warrant and the Warrant Stock issuable upon exercise hereof have not been registered under the Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein. Holder understands that this Warrant and the Warrant Stock issued upon any exercise hereof must be held indefinitely unless subsequently registered under the Act and qualified under applicable state securities laws, or unless exemption from such registration and qualification are otherwise available. Holder is aware of the provisions of Rule 144 promulgated under the Act.

7.5      No Voting Rights. Holder, as a Holder of this Warrant, will not have any voting rights until the conversion in whole or in part of this Warrant.

This Warrant and the Warrant Stock have not been registered under any securities laws. Accordingly, any share certificates issued pursuant to the conversion of this Warrant shall (until receipt of an opinion of counsel in customary form that such legend is no longer necessary) bear the following legend:

THIS WARRANT AND THE WARRANT STOCK ISSUABLE UPON CONVERSION HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”), AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE OFFER, SALE, PLEDGE, TRANSFER OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN CUSTOMARY FORM THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT.

Any notice or other communication required or permitted to be given here shall be in writing and shall be effective (a) upon hand delivery or delivery by e-mail or facsimile at the address or number designated below (if delivered on a business day during normal business hours where such notice is to be received) or the first business day following such delivery (if delivered other than on a business day during normal business hours where such notice is to be received), or (b) on the third business day following the date of mailing by express courier service, fully prepaid, addressed to such address, or upon actual receipt of such mailing, whichever shall first occur.
