ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

Merger Agreement

     On February 4, 2011, Endwave Corporation, a Delaware corporation (“Endwave”), GigOptix, Inc., a Delaware corporation (“GigOptix”), and Aerie Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of GigOptix (“Merger Subsidiary”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Merger Subsidiary will, subject to the satisfaction or waiver of the conditions therein, merge with and into Endwave, the separate corporate existence of Merger Subsidiary shall cease and Endwave will be the successor or surviving corporation of the merger (the “Merger”) and a wholly-owned subsidiary of GigOptix.

     Upon the consummation of the Merger, (i) the outstanding shares of Endwave common stock will be converted into the right to receive an aggregate number of shares of GigOptix common stock equal to the product of (.425/.575) and the number of shares of GigOptix common stock outstanding immediately prior to consummation of the Merger, less 42.5% of the Endwave Option Shares (as defined below) and (ii) in-the-money options to acquire Endwave common stock outstanding immediately prior to the consummation of the Merger will be converted into that number of shares of GigOptix common stock determined by dividing the spread value of such options at closing by the closing price of GigOptix’s common stock on the trading day prior to closing (such shares, the “Endwave Option Shares”), such that following the Merger, the pre-Merger holders of common stock and restricted stock units will own that number of shares equal to 42.5% of the outstanding stock of the combined company, less 42.5% of the shares issued in respect of Endwave stock options. If the Merger were consummated on February 4, 2011, each outstanding share of Endwave common stock would convert into approximately 0.89 shares of GigOptix common stock.

     The Merger Agreement contains customary “no-solicitation” covenants pursuant to which neither Endwave nor GigOptix is permitted to solicit any alternative acquisition proposals, provide any information to any person in connection with any alternative acquisition proposal, participate in any discussions or negotiations relating to any alternative acquisition proposal, approve, endorse or recommend any alternative acquisition proposal, or enter into any agreement relating to any alternative acquisition proposal. The “no-solicitation” provision is subject to certain exceptions that permit the Board of Directors of each of Endwave and GigOptix, as the case may be, to comply with their respective fiduciary duties, which, under certain circumstances, would enable Endwave or GigOptix, as the case may be, to provide information to, and engage in discussions or negotiations with, third parties with respect to alternative acquisition proposals.

     The Merger Agreement contains certain termination rights for both Endwave and GigOptix and further provides that, upon termination of the Merger Agreement under certain circumstances, Endwave may be obligated to pay GigOptix a termination fee of $1,000,000 plus certain reasonable documented expenses of GigOptix.

     GigOptix and Endwave currently expect to complete the Merger in the second quarter of 2011. GigOptix’s and Endwave’s obligations to consummate the Merger are subject to the satisfaction or waiver of customary closing conditions and regulatory approvals, as well as the approval of the merger by the stockholders of Endwave.

     Dr. Avi Katz will maintain his position as Chairman of the Board of Directors, Chief Executive Officer and President of the combined company. Curt P. Sacks, the current Chief Financial Officer of Endwave, will serve as the Chief Financial Officer of the combined company. Andrea Betti-Berutto, the current Chief Technology Officer of GigOptix, will serve as the Chief Technology Officer of the combined company. Other key executives from both companies will be combined to serve on the management team. GigOptix’s new Board of Directors will consist of all five existing GigOptix directors and two Endwave directors, John Mikulsky and Joseph Lazzara.

     The Boards of Directors of GigOptix and Endwave have each unanimously approved the Merger Agreement and the related transactions, and the Board of Directors of Endwave has also adopted resolutions recommending the requisite Endwave stockholder approval for consummation of the Merger. Endwave will hold a stockholders’ meeting to submit these matters to its stockholders for their consideration. In connection with the Merger, GigOptix intends to file with the U.S. Securities and Exchange Commission (“SEC”) a registration statement on Form S-4, which will include a proxy statement of Endwave and a prospectus of GigOptix.

     The Merger Agreement has been filed as an exhibit to this Form 8-K to provide information regarding the terms of the agreements and is not intended to modify or supplement any factual disclosures about GigOptix or Endwave in public reports filed with the SEC. The representations and warranties may be subject to a contractual standard of materiality different from those generally applicable to stockholders, or may have been used for the purpose of allocating risk between GigOptix and Endwave rather than establishing matters as facts. The foregoing description of the Merger Agreement does not purport to be complete, and is qualified in its entirety by reference to the full text of the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures. For the foregoing reasons, no person should rely on the representations and warranties as statements of factual information at the time they were made or otherwise. A copy of the Merger Agreement is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

Amendment to Rights Agreement

     On February 4, 2011, Endwave entered into that certain Amendment No. 2 to Rights Agreement (the “Rights Agreement Amendment”) with Computershare Trust Company, N.A., successor in interest to Computershare Trust Company, Inc., amending that certain Rights Agreement, dated as of December 1, 2005, as amended by that certain Amendment No. 1 to Rights Agreement, dated as of December 21, 2007 (the “Rights Agreement”). The Rights Agreement Amendment amended the terms of the Rights Agreement to exclude GigOptix and its affiliates from the definition of Acquiring Person thereunder, and to provide that the execution, delivery or performance of the Merger Agreement shall not trigger the rights set forth in the Rights Agreement.

     The description of the Rights Agreement, as modified by the Rights Agreement Amendment, is a summary only, does not purport to be complete, and is qualified in its entirety by reference to the full text of the Rights Agreement and the Rights Agreement Amendment. A copy of the Rights Agreement is attached as an exhibit to the Company’s Current Report on Form 8-K filed with the SEC on December 5, 2005 and is incorporated herein by reference. The

Rights Agreement Amendment is filed as Exhibit 4.1 hereto and is incorporated herein by reference.

Item 8.01 Other Events.

     On February 7, 2011, GigOptix and Endwave issued a joint press release announcing, among other things, the execution of the Merger Agreement. A copy of the press release is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

For the sake of example, based on the number of shares of GigOptix Common Stock which are issued and outstanding as of the Agreement Date as set forth in Section 4.04(a), the Total Merger Consideration would be 9,024,978 shares of GigOptix Common Stock.

ARTICLE II

CONVERSION OF SHARES

     Section 2.01 Conversion of Stock. Pursuant to the Merger, and without any action on the part of the holders of any outstanding shares of capital stock or securities of Endwave or Merger Sub:

     (a) As of the Effective Time, each share of Endwave Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Endwave Common Stock to be cancelled pursuant to Section 2.01(c) and any Dissenting Shares (as defined, and to the extent provided in Section 2.07)) (the “Converting Endwave Common Stock”) shall be automatically converted into such number of fully paid and nonassessable shares of GigOptix Common Stock equal to the Stock Merger Consideration divided by the sum of (i) the aggregate number of shares of Converting Endwave Common Stock and (ii) the aggregate number of shares of Endwave Common Stock issuable upon settlement of each Endwave Restricted Unit that is outstanding as of immediately prior to the Effective Time, whether or not vested (the “Conversion Ratio”). The shares of GigOptix Common Stock into which the Converting Endwave Common Stock are converted pursuant to this Section 2.01(a) shall constitute the “Merger Consideration”.

     (b) As of the Effective Time, each holder of record of Converting Endwave Common Stock shall cease to have any rights with respect thereto, except the right to receive (i) a certificate (or, at the Holder’s request, direct registration) representing the number of whole shares of GigOptix Common Stock into which such shares have been converted, and (ii) cash in lieu of fractional shares of GigOptix Common Stock in accordance with Section 2.01(f), without interest.

     (c) As of the Effective Time, each share of Endwave Common Stock held of record immediately prior to the Effective Time by Endwave, Merger Sub, GigOptix or any Subsidiary of GigOptix shall be cancelled and extinguished without any conversion thereof.

     (d) As of the Effective Time, each share of Common Stock, $0.001 par value, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be cancelled, extinguished and automatically converted into one validly issued, fully paid and nonassessable share of Common Stock, $0.001 par value, of the Surviving Corporation. Each certificate evidencing ownership of a number of shares of Merger Sub Common Stock shall be deemed to evidence ownership of the same number of shares of Common Stock, $0.001, of the Surviving Corporation.

     (e) In the event of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into capital stock), reorganization, reclassification, combination, recapitalization or other like change with respect to Endwave Common Stock or GigOptix Common Stock occurring after the Agreement Date and prior to the Effective Time, all references in this Agreement to specified numbers of shares of any class or series affected thereby, and all calculations provided for that are based upon numbers of shares

8

of any class or series (or trading prices therefor) affected thereby, shall be equitably adjusted to the extent necessary to provide the parties the same economic effect as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reorganization, reclassification, combination, recapitalization or other like change.

     (f) No fraction of a share of GigOptix Common Stock will be issued by virtue of the Merger. Instead, each Holder who would otherwise be entitled to a fraction of a share of GigOptix Common Stock (after aggregating all fractional shares of GigOptix Common Stock to be received by such holder) shall receive from GigOptix an amount of cash (rounded down to the nearest whole cent) equal to the product of (i) such fraction, multiplied by (ii) the GigOptix Closing Value. For the purposes of this Agreement, “GigOptix Closing Value” shall mean the closing price per share of GigOptix Common Stock as reported on the OTC Bulletin Board on the trading day immediately preceding the Effective Time.

     Section 2.02 Endwave Options and Restricted Stock Units. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Endwave Option that is outstanding and unexercised as of immediately prior to the Effective Time shall terminate and cease to represent a right to acquire Endwave Common Stock, and the holder thereof shall be entitled to receive therefor that number of shares of GigOptix Common Stock equal to (a) the product of (i) the difference between the closing price of Endwave’s Common Stock as reported on Nasdaq on the trading day immediately prior to the Effective Time and the per-share exercise price of such Endwave Option and (ii) the number of whole shares of Endwave Common Stock (with any fractional shares being settled in cash as provided in Section 2.01(f)) that were issuable upon exercise of Endwave Option, whether or not vested, divided by (b) the GigOptix Closing Value. The aggregate number of shares of GigOptix Common Stock to be issued pursuant to the prior sentence to the holders of the terminated Endwave Options shall be referred to herein as the “Endwave Option Shares”. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each Endwave Restricted Unit that is outstanding as of immediately prior to the Effective Time shall terminate and cease to represent a right to acquire Endwave Common Stock, and the holder thereof shall be entitled to receive that number of shares of GigOptix Common Stock equal to (a) the product of (i) the number of shares of Endwave Common Stock issuable upon settlement of such Endwave Restricted Unit, whether or not vested, and (ii) the Conversion Ratio. All such shares of GigOptix Common Stock issuable pursuant to this Section 2.02 (i) shall be subject to applicable withholding for federal, state and other taxes, such withholding to be satisfied by reducing the number of shares of GigOptix Common Stock (and cash in respect of fractional shares) otherwise issuable and (ii) shall not serve as an offset to or otherwise reduce the severance benefits to which a holder of Endwave Options or Endwave Restricted Units may otherwise be entitled. Endwave shall provide GigOptix all information (other than share price information) needed to effectuate such withholding at least three business days prior to the Effective Time. Endwave shall take all action necessary to terminate the Endwave Option Plans as of immediately prior to the Effective Time.

9

     Section 2.03 Endwave Stock Purchase Plan. By virtue of GigOptix not assuming outstanding rights of or substituting similar rights for participants under the Endwave Stock Purchase Plan, accumulated payroll deductions under the Endwave Stock Purchase Plan shall be used to purchase Endwave Common Stock immediately prior to the Effective Time. Endwave shall take all action necessary to terminate the Endwave Stock Purchase Plan as of the Effective Time.

     Section 2.04 Exchange of Stock Certificates.

     (a) At or prior to the Effective Time, GigOptix shall enter into an agreement with a bank or trust company selected by GigOptix and reasonably acceptable to Endwave to act as the exchange agent for the Merger (the “Exchange Agent”).

     (b) At or prior to the Effective Time, GigOptix shall supply or cause to be supplied to or for the account of the Exchange Agent in trust for the benefit of the Holders of Endwave Common Stock, for exchange pursuant to this Section 2.04 (i) certificates (or, at the Holder’s request, direct registration) evidencing the shares of GigOptix Common Stock issuable pursuant to Section 2.01 to be exchanged for outstanding shares of Endwave Common Stock, and (ii) cash in an aggregate amount sufficient to make the payments in lieu of fractional shares provided for in Section 2.01(f).

     (c) Promptly (and in no event more than five business days) after the Effective Time, GigOptix shall mail or shall cause to be mailed to each Holder a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Endwave Certificates shall pass, only upon proper delivery of the Endwave Certificates to the Exchange Agent) and instructions for surrender of the Endwave Certificates. Upon surrender to the Exchange Agent of an Endwave Certificate (if any), together with such letter of transmittal duly executed, the Holder shall be entitled to receive in exchange therefor (no later than five business days after the Exchange Agent’s receipt of the duly executed letter of transmittal and, if applicable, Endwave Certificate): (i) certificates evidencing that number of shares of GigOptix Common Stock issuable to such Holder in accordance with this Article II; (ii) any dividends or other distributions that such Holder has the right to receive pursuant to Section 2.04(d); and (iii) cash in respect of fractional shares as provided in Section 2.01(f), and such Endwave Certificate so surrendered shall forthwith be cancelled. No certificate representing shares of GigOptix Common Stock will be issued to a Person who is not the registered owner of a surrendered Endwave Certificate unless (i) the Endwave Certificate so surrendered has been properly endorsed or otherwise is in proper form for transfer, and (ii) such Person shall either (A) pay any transfer or other tax required by reason of such issuance or (B) establish to the reasonable satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered in accordance with the provisions of this Section 2.04, from and after the Effective Time, each Endwave Certificate (except an Endwave Certificate representing Dissenting Shares) shall be deemed to represent, for all purposes other than payment of dividends, the right to receive a certificate representing the number of full shares of GigOptix Common Stock as determined in accordance with this Article II and cash in lieu of fractional shares as provided in Section 2.01(f).

10

     (d) No dividend or other distribution shall be paid or declared with respect to GigOptix Common Stock prior to the Effective Time. No dividend or other distribution declared with respect to GigOptix Common Stock with a record date after the Effective Time will be paid to Holders of unsurrendered Endwave Certificates until such Holders surrender their Endwave Certificates. Upon the surrender of such Endwave Certificates, there shall be paid to such Holders, promptly after such surrender, the amount of dividends or other distributions, excluding interest, declared with a record date after the Effective Time and not paid because of the failure to surrender Endwave Certificates for exchange.

     (e) Notwithstanding anything to the contrary in this Agreement, neither the Exchange Agent, GigOptix, the Surviving Corporation nor any party hereto shall be liable to any Holder for shares of GigOptix Common Stock or cash in lieu of fractional shares delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

     Section 2.05 Lost, Stolen or Destroyed Certificates. In the event that any Endwave Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue and pay in respect of such lost, stolen or destroyed Endwave Certificates, upon the making of an affidavit of that fact by the Holder thereof, certificates representing the shares of GigOptix Common Stock as may be required pursuant to Section 2.01 and cash in lieu of fractional shares, if any, as may be required pursuant to Section 2.01(f) and any dividends or distributions payable pursuant to Section 2.04(d); provided, however, that GigOptix may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Endwave Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against GigOptix or the Exchange Agent with respect to the Endwave Certificates alleged to have been lost, stolen or destroyed.

     Section 2.06 Tax Consequences. For United States federal income tax purposes, it is intended by the parties hereto that this Agreement is a “plan of reorganization” and that the Merger qualify as a reorganization within the meaning of Section 368(a) of the Code.

     Section 2.07 Appraisal Rights.

     (a) Notwithstanding any provision of this Agreement to the contrary other than Section 2.07(b), any shares of Endwave Common Stock held by an Endwave Stockholder who has demanded and perfected appraisal rights for such shares in accordance with Delaware Law and who, as of the Effective Time, has not effectively withdrawn or lost such appraisal rights (“Dissenting Shares”), shall not be converted into or represent a right to receive Merger Consideration pursuant to Section 2.01, but instead shall be converted into the right to receive only such consideration as may be determined to be due with respect to such Dissenting Shares under the laws of the State of Delaware. From and after the Effective Time, a holder of Dissenting Shares shall not be entitled to exercise any of the voting rights or other rights of a stockholder of the Surviving Corporation.

     (b) Notwithstanding the provisions of Section 2.01(a), if any Endwave Stockholder who demands appraisal of such shares under Delaware Law shall effectively withdraw or lose

11

(through failure to perfect or otherwise) the right to appraisal, then, as of the later of the Effective Time and the occurrence of such event, such Endwave Stockholder’s shares shall no longer be Dissenting Shares and shall automatically be converted into and represent only the right to receive the Merger Consideration as provided in Section 2.01(a), without interest thereon, upon surrender of the certificate representing such shares pursuant to Section 2.04.

     (c) Endwave shall give GigOptix (i) prompt notice of any written demands for appraisal of any shares of Endwave Common Stock, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by Endwave which relate to any such demand for appraisal and (ii) the opportunity to participate in all negotiations and proceedings which take place prior to the Effective Time with respect to demands for appraisal under Delaware Law. Endwave shall not, except with the prior written consent of GigOptix, voluntarily make any payment with respect to any demands for appraisal of Endwave Common Stock or offer to settle or settle any such demands.

Except for this Agreement and except as listed on Section 3.11(a) of the Endwave Disclosure Schedule, none of Endwave or its Subsidiaries is a party to or bound by any Contract: (i) that would be required to be filed by Endwave as a “material contract” pursuant to Item 601(b)(10) of Regulation S-K under the Securities Act; (ii) containing covenants binding upon Endwave or its Subsidiaries that materially restrict the ability of Endwave or its Subsidiaries (or which, following the consummation of the Merger, would materially restrict the ability of the Surviving Corporation) to compete in any business or geographic area that is material to Endwave and its Subsidiaries, taken as a whole, as of the date hereof, except for any such Contract that may be cancelled without penalty by Endwave or its Subsidiaries upon notice of sixty (60) days or less; or (iii) that would prevent, materially delay or materially impede Endwave’s ability to consummate the Merger or the other transactions contemplated by this Agreement. Each such Contract described in clauses (i) through (iii) is referred to herein as an “Endwave Material Contract.”

     (b) Each of the Endwave Material Contracts is valid and binding on Endwave or its Subsidiaries, as the case may be, and, to the knowledge of Endwave, each other party thereto and is in full force and effect, except for such failures to be valid and binding or to be in full force and effect as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. There is no default under any Endwave Material Contract by Endwave or its Subsidiaries and no event has occurred that with the lapse of time or the giving of notice or both would constitute a default thereunder by Endwave or its Subsidiaries, in each case except as

22

would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

     (c) Notwithstanding anything in this Section 3.11, “Endwave Material Contract” shall not include any Contract that (i) is terminable upon ninety (90) days’ or less notice without a penalty premium and does not contain payment obligations of Endwave or its Subsidiaries in excess of $100,000 or (ii) is solely between Endwave and one or more of its Subsidiaries or is solely between Subsidiaries of Endwave.

Neither Endwave nor any of its Subsidiaries has received any written, or, to Endwave’s knowledge, oral notice or other communication regarding any actual or possible violation or material breach of or material default under, or intention to cancel, call a default under, or modify, any Endwave Material Contract.

     (b) Except as listed in Section 3.12(b) of the Endwave Disclosure Schedule, neither Endwave nor any of its Subsidiaries is a party to, and no asset or property of Endwave or any of its Subsidiaries is bound or affected by, any judgment, injunction, order or decree, that restricts or prohibits Endwave, any of its Subsidiaries or, following the Effective Time, will restrict or prohibit the Surviving Corporation, GigOptix or any of its Subsidiaries, from freely engaging in the Endwave Business or from competing anywhere in the world (including any judgments, injunctions, orders or decrees, restricting the geographic area in which Endwave or any of its Subsidiaries may sell, license, market, distribute or support any products or technology or provide services or restricting the markets, customers or industries that Endwave or any of its Subsidiaries may address in operating the Endwave Business or restricting the prices which Endwave or any of its Subsidiaries may charge for its products, technology or services (including most favored customer pricing provisions)), or includes any grants by Endwave or any of its Subsidiaries of exclusive rights or licenses, rights of refusal, rights of first negotiation or similar rights.

As used in this Agreement, “Endwave-Owned IP Rights” means Endwave IP Rights that are owned or purported to be owned by Endwave or its Subsidiaries; and “Endwave-Licensed IP Rights” means Endwave IP Rights that are licensed to Endwave or its Subsidiaries by a third party.

     (b) Neither the execution, delivery and performance of this Agreement nor the consummation of the Merger and the other transactions contemplated by this Agreement shall, pursuant to any Contract to which Endwave or its Subsidiaries is a party, in accordance with its terms: (i) constitute a material breach of or default under any such Contract governing any Endwave IP Right (collectively, the “Endwave IP Rights Agreements”); (ii) cause the forfeiture or termination of, or give rise to a right of forfeiture or termination of, any Endwave IP Right; or (iii) materially impair the right of Endwave, its Subsidiaries or the Surviving Corporation to use, make, market, license, sell, copy, distribute, or dispose of any Endwave IP Right or portion thereof.

     (c) To the knowledge of Endwave, neither the operation of the Endwave Business nor the use, development, manufacture, marketing, license, sale, distribution or furnishing of any product or service, including, without limitation, all software, firmware, middleware, databases, interfaces, systems, devices, hardware, equipment, other tangible items designed, developed, produced, manufactured, assembled, sold, leased, installed, repaired, licensed, marketed, furnished, distributed or otherwise made available by Endwave or its Subsidiaries (each an “Endwave Product or Service”) as designed, developed, produced, manufactured, assembled, sold, leased, installed, repaired, licensed, marketed, furnished, distributed or otherwise by Endwave and its Subsidiaries as of the date of this Agreement (i) violates any license or other Contract between Endwave or its Subsidiaries and any third party, or (ii) infringes or misappropriates any Intellectual Property right of any other party. There is no pending, or to the knowledge of Endwave, threatened in writing, claim or litigation contesting the validity, ownership or right of Endwave or its Subsidiaries to use, develop, make, market, license, sell, distribute or furnish any Endwave-Owned IP Right or Endwave Product or Service, nor to the knowledge of Endwave is there any legitimate basis for any such claim, nor since January 1, 2008 has Endwave or its Subsidiaries received any written notice asserting that any Endwave-

24

Owned IP Right or the use, development, manufacture, marketing, licensing, sale, distribution, furnishing or disposition thereof conflicts with or infringes the rights of any other party, nor to the knowledge of Endwave is there any legitimate basis for any such assertion. Since January 1, 2008, Endwave and each of its Subsidiaries have not received any written notice from any third party notifying any of them of, or requesting that any of them enter into a license under, any third party patents. None of the Endwave-Owned IP Rights or Endwave Products or Services of Endwave or its Subsidiaries is subject to any proceeding or outstanding order or stipulation to which Endwave or any of its Subsidiaries is a party (i) restricting in any manner the use, development, manufacture, marketing, licensing, sale, distribution, furnishing or disposition by Endwave or its Subsidiaries of any Endwave-Owned IP Rights, any Endwave Product or Service, or which may affect the validity, use or enforceability of any such Endwave-Owned IP Rights or Endwave Product or Service, or (ii) restricting the conduct of the Endwave Business in order to accommodate Intellectual Property rights of a third party.

     (d) To Endwave’s knowledge, no current or former employee, consultant or independent contractor of Endwave or any of its Subsidiaries: (i) is in material violation of any term or covenant of any employment contract, patent disclosure agreement, invention assignment agreement, nondisclosure agreement, noncompetition agreement or any other Contract with any other party by virtue of such employee’s, consultant’s or independent contractor’s being employed by, or performing services for, Endwave or any of its Subsidiaries or using trade secrets or proprietary information of others without permission; or (ii) has developed any technology, software or other copyrightable, patentable or otherwise proprietary work for Endwave or any of its Subsidiaries that is subject to any Contract under which such employee, consultant or independent contractor has assigned or otherwise granted to any third party any rights (including Intellectual Property) in or to such technology, software or other copyrightable, patentable or otherwise proprietary work except as directed by Endwave or any of its Subsidiaries. To Endwave’s knowledge, neither the employment of any employee of Endwave or any of its Subsidiaries, nor the use by Endwave or any of its Subsidiaries of the services of any consultant or independent contractor subjects Endwave or any of its Subsidiaries to any Liability to any third party (including for improperly soliciting such employee, consultant or independent contractor to work for Endwave or any of its Subsidiaries).

     (e) Endwave and each of its Subsidiaries have taken commercially reasonable steps to protect, preserve and maintain the secrecy and confidentiality of the Endwave IP Rights and to preserve and maintain all Endwave’s and each of its Subsidiaries’ interests, proprietary rights and trade secrets in the Endwave IP Rights. All current and former officers, employees, consultants and independent contractors of Endwave, each of its Subsidiaries, and each of its and their predecessors having access to proprietary information of Endwave, each of its Subsidiaries, and each of its and their predecessors, including any inventions and any proprietary information received by Endwave or any of its Subsidiaries from any of their respective customers and partners have executed and delivered to Endwave or its predecessors and its Subsidiaries or their predecessors an agreement regarding the protection of such proprietary information (in the case of proprietary information of their respective customers and business partners, to the extent required by such customers and business partners); and copies of all such agreements have been

25

delivered to GigOptix. Endwave, each of its Subsidiaries, and each of its and their predecessors have secured valid written assignments from all of their current and former consultants, independent contractors and employees who were involved in, or who contributed to, the creation or development of any material Endwave-Owned IP Rights, of the rights to such contributions that may be owned by such persons or that Endwave, each of its Subsidiaries, and each of its and their predecessors did not or do not already own by operation of law, except where such assignment is not permitted by Applicable Law. No current or former employee, officer, director, consultant or independent contractor of Endwave, any of its Subsidiaries or any of its or their predecessors has any right, license, claim or interest whatsoever in or with respect to any Endwave-Owned IP Rights.

     (f) To the knowledge of Endwave, all registered patents, trademarks, service marks, Internet domain names, Internet or World Wide Web URLs or addresses, copyrights and mask work rights that are material Endwave-Owned IP Rights are valid and subsisting, and Endwave or its Subsidiaries are the record owner thereof. To the knowledge of Endwave, all registered patents, trademarks and service marks, are currently in compliance with all legal requirements other than any requirement, that if not satisfied, with respect to a patent would not result in a revocation or lapse or otherwise adversely affect its enforceability, and with regard to a trademark or service mark would not result in a cancellation of such registration or otherwise adversely affect the use, priority or enforceability of the trademark or service mark. To the knowledge of Endwave, Endwave, each of its Subsidiaries, and each of its and their predecessors have not taken any action or failed to take any action, or used or enforced (or failed to use or enforce) any of the patents for which any of them has applied for or been issued a registration in a manner that would result in the abandonment or unenforceability of such patent. Endwave or its Subsidiaries are the exclusive owners of all trademarks and, to the knowledge of Endwave, trade names used in connection with the operation or conduct of the Endwave Business, including the sale, licensing, distribution or provision of any Endwave Products or Services by Endwave or any of its Subsidiaries.

     (g) Endwave or its Subsidiaries own all right, title and interest in and to all material Endwave-Owned IP Rights free and clear of all Encumbrances (other than Permitted Encumbrances) and licenses (other than licenses and rights listed in Section 3.13(g) of the Endwave Disclosure Schedule and non-exclusive licenses provided on Endwave’s or its Subsidiary’s standard form of agreement, without material deviation).

     (h) Except as set forth in Section 3.13(h)-1 of the Endwave Disclosure Schedule or in a standard customer agreement for Endwave and its Subsidiaries, there are no unfulfilled performance commitments under any license, sublicense or Contract, including specified upgrades and undelivered elements, except for maintenance services which have not yet been provided as it related to undelivered elements. Except as set forth on Section 3.13(h)-2 of the Endwave Disclosure Schedule, none of the licenses or other Contracts of Endwave grants any third party exclusive rights to or under any Endwave-Owned IP Rights or grants any third party the right to sublicense any of such Endwave-Owned IP Rights.

     (i) Neither Endwave, nor any of its Subsidiaries, nor any other party authorized to act on any of their behalves has disclosed or delivered to any party (other than any employee or contractor of Endwave or any of its subsidiaries in the course of their performance of work for Endwave or its Subsidiary), or permitted the disclosure or delivery to any escrow agent or other party of, any Endwave Source Code (as defined below). To the knowledge of Endwave, no event has occurred, and no circumstance or condition exists, that (with or without notice or lapse of time, or both) shall, or would reasonably be expected to, result in the disclosure or delivery by Endwave, or any of its Subsidiaries or any other party authorized to act on any of their behalves to any party of any Endwave Source Code. Except as set forth in Section 3.13(i) of the Endwave Disclosure Schedule, neither Endwave nor any of its Subsidiaries has deposited, or is or may be required to deposit, with an escrow agent or other party, any Endwave Source Code and neither the execution of this Agreement nor the consummation of the Merger or any of the other transactions contemplated by this Agreement, in and of itself, would reasonably be expected to result in the release from escrow of any Endwave Source Code. As used in this Section 3.13(i), “Endwave Source Code” means, collectively, the source code of any software or program (i.e., software code in its original, human readable, un-compiled, form), or any portion, aspect or segment of any source code, or any material proprietary information or algorithm contained in or relating to any software source code, owned by or licensed to Endwave, or its Subsidiaries, or otherwise used by Endwave or any of its Subsidiaries, or marketed or currently proposed to be marketed by Endwave or any of its Subsidiaries.

There is no intention to change the terms of any Governmental Grant, except as may result from generally applicable changes to the relevant laws and regulations thereunder.

     Section 3.15 Certain Transactions and Agreements. Since January 1, 2009, neither Endwave nor any of its Subsidiaries has entered into any material transaction with any Affiliate

30

of Endwave or any of its Subsidiaries or any transaction that would be required to be reported by Endwave pursuant to Item 404 of Regulation S-K under the Securities Act that has not been so reported.

     Section 3.16 Employees, ERISA and Other Compliance.

     (a) To the knowledge of Endwave, Endwave and each of its Subsidiaries have always been and currently are in compliance in all material respects with all Applicable Law and Contracts relating to employment, employment practices, immigration, wages, hours, and terms and conditions of employment, including employee compensation matters, and have correctly classified employees as exempt employees and nonexempt employees under the Fair Labor Standards Act and the California Labor Code. To the knowledge of Endwave, all employees of Endwave and each of its Subsidiaries are legally permitted to be employed by Endwave and such Subsidiary in the jurisdiction in which such employee is employed in their current job capacities for the maximum period allowed under Applicable Law. To Endwave’s knowledge, all independent contractors providing services to Endwave and each of its Subsidiaries have been properly classified as independent contractors for purposes of federal and applicable state tax laws, laws applicable to employee benefits and other Applicable Law. Except as set forth on Section 3.16(a) of the Endwave Disclosure Schedule, Endwave and each of its Subsidiaries do not have any employment or consulting Contracts currently in effect that are not terminable at will (other than agreements with the sole purpose of providing for the confidentiality of proprietary information or assignment of inventions). To the knowledge of Endwave as of the Agreement Date, no employees or consultants of Endwave or any of its Subsidiaries have given notice to Endwave or such Subsidiary of an intention to terminate his or her employment or relationship with Endwave or such Subsidiary.

     (b) To the knowledge of Endwave, Endwave and each of its Subsidiaries are not now, nor have ever been, subject to a union organizing effort. Endwave and each of its Subsidiaries are not subject to any collective bargaining agreement with respect to any of their employees, subject to any other Contract with any trade or labor union, employees’ association or similar organization, or subject to any current disputes with a labor organization. Endwave and each of its Subsidiaries have good labor relations, and Endwave has no knowledge of any facts indicating that the consummation of the Merger or any of the other transactions contemplated hereby shall have a material adverse effect on such labor relations. As of the date of this Agreement, Endwave has no knowledge of any facts indicating that any Endwave employee has filed or intends to file an internal or external complaint regarding his or her employment at Endwave, including, without limitation, complaints of discriminations, harassment, retaliation, and / or unpaid wages.

     (c) Neither Endwave nor any ERISA Affiliate of Endwave has participated in a pension plan which constitutes, or has since the enactment of ERISA, constituted, a “multiemployer plan” as defined in Section 3(37) of ERISA or a “multiple employer plan” as defined in Section 413(c) of the Code. No pension plan of Endwave or an ERISA Affiliate of Endwave is subject to Title IV of ERISA.

31

     (d) Each employment, consulting, severance or other similar written Contract, each “employee benefit plan” as defined in Section 3(3) of ERISA and each written plan or arrangement providing for insurance coverage (including any self-insured arrangements that are clearly identified as such), workers’ benefits, vacation benefits, severance benefits, disability benefits, death benefits, hospitalization benefits, retirement benefits, deferred compensation, profit-sharing, bonuses, stock options, stock purchase, phantom stock, stock appreciation or other forms of incentive compensation or post-retirement insurance, compensation or benefits for employees, consultants or directors that is entered into, maintained or contributed to by Endwave, any Subsidiary of Endwave or any ERISA Affiliate of Endwave and covers any employee or former employee of Endwave, its predecessors or any Subsidiary of Endwave or ERISA Affiliate of Endwave (excluding any government plans, programs or mandates) (collectively referred to as “Endwave Benefit Arrangements”) have been maintained, including as to form, in compliance in all material respects with their terms and with the requirements prescribed by any and all Applicable Law. No Endwave Benefit Arrangement is an “employee pension benefit plan” as defined in Section 3(2) of ERISA that is subject to Section 412 of the Code or Section 302 of ERISA. No Endwave Benefit Arrangement or assets associated therewith is subject to any surrender fees or services fees upon termination other than the normal and reasonable administrative fees associated with the termination of benefit plans. Subject to Applicable Laws, Endwave has the right under the terms of each applicable Endwave Benefit Arrangement to terminate such Endwave Benefit Arrangement (or terminate the participation in such Endwave Benefit Arrangement by Endwave), and no additional contribution would be required to properly effect such termination.

     (e) No suit, administrative proceeding, action or other litigation has been brought, or to the knowledge of Endwave is threatened in writing against or with respect to any Endwave Benefit Arrangement (other than claims for benefits under such Endwave Benefit Arrangement that are routine), including any audit or inquiry by the Internal Revenue Service (“IRS”) or the Department of Labor (“DOL”). No “prohibited transaction” (as defined in Section 4975 of the Code or Section 406 of ERISA) has occurred that involves the assets of any Endwave Benefit Arrangements and that is reasonably likely to subject Endwave, any of the its Subsidiaries, or any of their employees to a material tax or penalty on prohibited transactions imposed by Section 4975 of the Code or material sanctions imposed under Title I of ERISA.

     (f) All contributions due from Endwave with respect to any of the Endwave Benefit Arrangements have been made or have been accrued on Endwave’s financial statements, and no further contributions shall be due or shall have accrued thereunder as of the Closing Date (other than contributions accrued in the ordinary course of business, consistent with past practices, after the Endwave Balance Sheet Date as a result of the operations of Endwave after the Endwave Balance Sheet Date).

     (g) All individuals who, pursuant to the terms of any Endwave Benefit Arrangement, are entitled to participate in any Endwave Benefit Arrangement, are currently participating in such Endwave Benefit Arrangement or have been offered an opportunity to do so and have declined to do so.

32

     (h) There has been no amendment to, written interpretation or announcement (whether or not written) by Endwave relating to, or change in employee participation or coverage under, any Endwave Benefit Arrangement that would increase materially the expense of maintaining such Endwave Benefit Arrangement above the level of the expense incurred in respect thereof during the calendar year 2010 (other than increased insurance premiums), except any such amendments that are required under Applicable Law. Except as set forth on Section 3.16(h) to the Endwave Disclosure Schedule, the execution of this Agreement and the consummation of the transactions contemplated by this Agreement will not (either alone or in connection with the termination of employment or change of position of any employee following or in connection with the consummation of the Merger) constitute an event under any Endwave Benefit Arrangement that will or may result in any material payment (whether severance pay or otherwise), acceleration of payment, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any employee.

     (i) Except as set forth on Section 3.16(i) to the Endwave Disclosure Schedule, no benefit payable or that may become payable by Endwave or any of its Subsidiaries pursuant to any Endwave Benefit Arrangement as a result of, in connection with or arising under this Agreement or the Certificate of Merger shall constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code) that is subject to the imposition of an excise tax under Section 4999 of the Code or that would not be deductible by reason of Section 280G of the Code. Unless otherwise indicated in Section 3.16(j) of the Endwave Disclosure Schedule, Endwave and each of its Subsidiaries are not a party to any: (i) Endwave Benefit Arrangement with any executive officer or other key employee thereof (A) the benefits of which are contingent, or the terms of which are materially altered, upon the occurrence of a transaction involving Endwave in the nature of the Merger or any of the other transactions contemplated by this Agreement, (B) providing any term of employment or compensation guarantee, or (C) providing severance benefits or other benefits after the termination of employment of such employee regardless of the reason for such termination of employment other than as required by Consolidation Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) (or similar state laws), vacation pay cash-outs or other arrangements governed by ERISA; or (ii) Endwave Benefit Arrangement, including any stock option plan, stock appreciation rights plan or stock purchase plan, any of the benefits of which shall be increased, or the vesting of benefits of which shall be accelerated, by the occurrence of the Merger or any of the other transactions contemplated by this Agreement, or any event subsequent to the Merger such as the termination of employment of any person, or the value of any of the benefits of which shall be calculated on the basis of any of the transactions contemplated by this Agreement. Endwave and each of its Subsidiaries have no obligation to pay any material amount or provide any material benefit to any former employee or officer, other than obligations (i) for which Endwave has established a reserve for such amount on the Endwave Balance Sheet, (ii) pursuant to Contracts entered into after the Endwave Balance Sheet Date and disclosed on Section 3.16(i) of the Endwave Disclosure Schedule and (iii) arising from governmentally mandated benefits.

     (j) To Endwave’s knowledge, no employee or consultant of Endwave or any of its Subsidiaries is in material violation of (i) any term of any employment or consulting Contract or

33

(ii) any term of any other Contract or any restrictive covenant relating to the right of any such employee or consultant to be employed by Endwave or any of its Subsidiaries or to use trade secrets or proprietary information of others. To Endwave’s knowledge, the employment of any employee or consultant by Endwave and each of its Subsidiaries does not subject it to any material Liability to any third party other than Liabilities with respect to employer payroll tax and employee tax withholding.

     (k) Endwave and each of its Subsidiaries have not established any compensation or benefit plan that is maintained or is required to be maintained or contributed to by the law or applicable custom or rule of a jurisdiction outside of the United States.

     (l) In the past two years, there has been no “mass layoff,” “employment loss,” or “plant closing” as defined by the Workers Adjustment and Retraining Notification Act (the “WARN Act”) in respect of Endwave or any of its Subsidiaries.

     (m) All required reports and descriptions of each Endwave Benefit Arrangement (including Internal Revenue Service Form 5500 annual reports, summary annual reports, summary plan descriptions and summaries of material modifications) have been timely filed with the IRS, the DOL or other governmental body and have been distributed as required.

     (n) The form of each Endwave Benefit Arrangement that is subject to Section 409A of the Code meets the requirements of Sections 409A(a)(2), (3) and (4) of the Code and has been operated in accordance with such requirements.

     (o) No amount previously paid or that is payable or that may become payable by Endwave or any of its Subsidiaries pursuant to any Endwave Benefit Arrangement or as a result of, in connection with or arising under this Agreement or the Certificate of Merger shall fail to be deductible under Section 162(m) of the Code.

     Section 3.17 Merger Expenses. No Person other than Merriman Capital, Inc. is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of Endwave or any of its Subsidiaries. The legal and accounting advisors, and any other persons, to whom Endwave currently expects to owe fees and expenses that will constitute Merger Expenses are set forth on Section 3.17 of the Endwave Disclosure Schedule, and other than the Merger Expenses that will be due to the entities set forth on Section 3.17 of the Endwave Disclosure Schedule, there are no Merger Expenses.

     Section 3.18 Insurance. Endwave and each of its Subsidiaries maintain the policies of insurance and bonds set forth in Section 3.18 of the Endwave Disclosure Schedule, including all legally required workers’ compensation and other insurance. Section 3.18 of the Endwave Disclosure Schedule sets forth the name of the insurer under each such policy and bond, the type of policy or bond, and the coverage amount and any applicable deductible. There is no material claim pending under any of such policies or bonds as to which coverage has been questioned, denied or disputed by the underwriters of such policies or bonds. All premiums due and payable under all such policies and bonds have been timely paid, and Endwave and each of its

34

Subsidiaries are otherwise in compliance in all material respects with the terms of such policies and bonds. All such policies and bonds remain in full force and effect, and Endwave has no knowledge of any threatened termination of, or material premium increase with respect to, any of such policies or bonds. All such policies provide insurance coverage for Endwave’s or its Subsidiaries assets and operation of the Endwave Business, of the kinds, in the amounts and against the risks required to comply with Applicable Law and/or any contractual or other obligations, and such policies are of the scope and amount customary and reasonable for the businesses in which Endwave and its Subsidiaries has engaged. Neither Endwave nor any of its Subsidiaries has been refused any insurance with respect to any aspect of the operations of its business, nor has its coverage been limited by any insurance carrier to which it has applied for insurance or with which it has carried insurance. The activities and operations of Endwave and each of its Subsidiaries have been conducted in a manner so as to materially conform to all applicable provisions of such policies and bonds. Endwave has delivered to GigOptix correct and complete copies of all such policies of insurance and bonds issued at the request or for the benefit of Endwave.

To the knowledge of Endwave, Endwave and its predecessors and Affiliates are in material compliance with all Environmental Laws, which compliance includes the possession by Endwave of all material permits and other governmental authorizations required under Environmental Laws and compliance with the terms and conditions thereof. Endwave has not received any written notice or other written communication, whether from a Governmental Authority, citizens groups, employee or otherwise, that alleges that Endwave is not in compliance with any Environmental Law, and to the knowledge of Endwave, there are no circumstances that may prevent or interfere with the compliance by Endwave with any current Environmental Law in the future. To the knowledge of Endwave, no current or prior owner of any property leased or possessed by Endwave has received any written notice or other written communication, whether from a Governmental Authority, citizens group, employee or otherwise, that alleges that such current or prior owner or Endwave is not in compliance with any Environmental Law.

Since January 1, 2011, Endwave has not received any written or, to Endwave’s knowledge, oral notice from any Endwave Significant Customer that such customer shall not continue as a customer of Endwave or any of its Subsidiaries or that such customer intends to terminate or materially modify existing Contracts with Endwave (or the Surviving Corporation, GigOptix or any of its Subsidiaries) or

35

that such customer refuses to make payments for products delivered or services rendered. Endwave has not had any of its products returned by an Endwave Significant Customer thereof except for normal warranty returns consistent with past history and those returns that would not result in a reversal of any material amount of revenue by Endwave.

     (b) Endwave has no outstanding material dispute concerning products and/or services provided by any supplier who, in the year ended December 31, 2010 was one of the 10 largest suppliers of products and/or services to Endwave, based on amounts paid or payable (each, an “Endwave Significant Supplier”) and Endwave has no knowledge of any material dissatisfaction on the part of any Endwave Significant Supplier.

No pension plan of GigOptix or an ERISA Affiliate of GigOptix is subject to Title IV of ERISA.

56

     (d) Each employment, consulting, severance or other similar written Contract, each “employee benefit plan” as defined in Section 3(3) of ERISA and each written plan or arrangement providing for insurance coverage (including any self-insured arrangements that are clearly identified as such), workers’ benefits, vacation benefits, severance benefits, disability benefits, death benefits, hospitalization benefits, retirement benefits, deferred compensation, profit-sharing, bonuses, stock options, stock purchase, phantom stock, stock appreciation or other forms of incentive compensation or post-retirement insurance, compensation or benefits for employees, consultants or directors that is entered into, maintained or contributed to by GigOptix, any Subsidiary of GigOptix or any ERISA Affiliate of GigOptix and covers any employee or former employee of GigOptix, its predecessors or any Subsidiary of GigOptix or ERISA Affiliate of GigOptix (excluding any government plans, programs or mandates) (collectively referred to as “GigOptix Benefit Arrangements”) have been maintained, including as to form, in compliance in all material respects with their terms and with the requirements prescribed by any and all Applicable Law. No GigOptix Benefit Arrangement is an “employee pension benefit plan” as defined in Section 3(2) of ERISA that is subject to Section 412 of the Code or Section 302 of ERISA.

The execution of this Agreement and the consummation of the transactions contemplated by this Agreement will not (either alone or in connection with the termination of employment or change of position of any employee following or in connection with the consummation of the Merger) constitute an event under any GigOptix Benefit Arrangement that will or may result in any material payment (whether severance pay or otherwise), acceleration of payment, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any employee.

     (i) To GigOptix’s knowledge, no employee or consultant of GigOptix or any of its Subsidiaries is in material violation of (i) any term of any employment or consulting Contract or (ii) any term of any other Contract or any restrictive covenant relating to the right of any such employee or consultant to be employed by GigOptix or any of its Subsidiaries or to use trade secrets or proprietary information of others.

     (j) GigOptix and each of its Subsidiaries have not established any compensation or benefit plan that is maintained or is required to be maintained or contributed to by the law or applicable custom or rule of a jurisdiction outside of the United States.

     (m) The form of each GigOptix Benefit Arrangement that is subject to Section 409A of the Code meets the requirements of Sections 409A(a)(2), (3) and (4) of the Code and has been operated in accordance with such requirements.

     (n) No amount previously paid or that is payable or that may become payable by GigOptix or any of its Subsidiaries pursuant to any GigOptix Benefit Arrangement or as a result of, in connection with or arising under this Agreement or the Certificate of Merger shall fail to be deductible under Section 162(m) of the Code.

     Section 4.17 Insurance. GigOptix and each of its Subsidiaries maintain the policies of insurance and bonds set forth in Section 4.17 of the GigOptix Disclosure Schedule, including all legally required workers’ compensation and other insurance. Section 4.17 of the GigOptix

58

All such policies and bonds remain in full force and effect, and GigOptix has no knowledge of any threatened termination of, or material premium increase with respect to, any of such policies or bonds. All such policies provide insurance coverage for GigOptix’s or its Subsidiaries assets and operation of the GigOptix Business, of the kinds, in the amounts and against the risks required to comply with Applicable Law and/or any contractual or other obligations, and such policies are of the scope and amount customary and reasonable for the businesses in which GigOptix and its Subsidiaries has engaged. Neither GigOptix nor any of its Subsidiaries has been refused any insurance with respect to any aspect of the operations of its business, nor has its coverage been limited by any insurance carrier to which it has applied for insurance or with which it has carried insurance. The activities and operations of GigOptix and each of its Subsidiaries have been conducted in a manner so as to materially conform to all applicable provisions of such policies and bonds. GigOptix has delivered to Endwave correct and complete copies of all such policies of insurance and bonds issued at the request or for the benefit of GigOptix.

Since January 1, 2011, GigOptix has not received any written notice from any GigOptix Significant Supplier that such supplier shall not continue as a supplier to GigOptix or any of its Subsidiaries or that such supplier intends to terminate or materially modify existing Contracts with GigOptix (or the Surviving Corporation, Endwave or any of its Subsidiaries).

The board of directors of GigOptix has received the opinion of Roth Capital Partners, dated as of the Agreement Date, based on and subject to the assumptions, matters considered and limitations described therein, regarding the fairness to GigOptix from a financial point of view of the Merger Consideration to be paid by GigOptix in connection with the Merger.

     Section 4.24 Disclosure. No representation or warranty of GigOptix in this Agreement and no statement in the GigOptix Disclosure Schedule omits to state a material fact necessary to make the statements herein or therein, in light of the circumstances in which they were made, not misleading.

     Section 4.25 Reorganization. None of GigOptix, any of its Subsidiaries nor, to the knowledge of GigOptix, any of GigOptix’s Affiliates has taken or agreed to take any action that would prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368 of the Code and GigOptix is not aware of any agreement, plan or other circumstance that would prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368 of the Code.

     Section 5.02 No Solicitation.

     (a) From and after the Agreement Date until the Effective Time or termination of this Agreement pursuant to Article VIII, Endwave and its Subsidiaries will not, nor will they authorize or permit any of their respective officers, directors, affiliates or employees or any investment banker, attorney or other advisor or representative retained by any of them to, directly or indirectly, (i) solicit, initiate, encourage or induce the making, submission or announcement of any Endwave Acquisition Proposal (as hereinafter defined), (ii) participate in any discussions or negotiations regarding, or furnish to any person any non-public information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any Endwave Acquisition Proposal, (iii) engage in discussions with any person with respect to any Endwave Acquisition Proposal, except as to the existence of these provisions, (iv) approve, endorse or recommend any Endwave Acquisition Proposal or (v) enter into any letter of intent or similar document or any contract agreement or commitment contemplating or otherwise relating to any Endwave Acquisition Transaction. Notwithstanding anything to the contrary contained in this Section 5.02 or in any other provision of this Agreement, Endwave and its board of directors: (i) may furnish information to, or participate in discussions with, any third party that has made an unsolicited Endwave Acquisition Proposal (a “Potential Acquirer”) that the board of directors reasonably concludes may lead to an Endwave Superior Offer (as defined in Section 5.04(c) hereof); and (ii) may participate in discussions or negotiations with any Potential Acquirer or approve an unsolicited Endwave Acquisition Proposal if the board of directors is advised by its financial advisor that the Potential Acquirer submitting such Endwave Acquisition Proposal has the financial wherewithal to be reasonably capable of consummating such an Endwave Acquisition Proposal, and the board of

64

directors determines in good faith, (A) after receiving advice from its financial advisor, that such Endwave Acquisition Proposal is an Endwave Superior Offer (as defined in Section 5.04(c) hereof), and (B) after consultation with its legal counsel, that the failure to participate in such discussions or negotiations or to furnish such information or approve an Endwave Acquisition Proposal would be inconsistent with the board of directors’ fiduciary duties under Applicable Law. Endwave agrees that any non-public information furnished to a Potential Acquirer will be pursuant to a confidentiality, standstill and nonsolicitation agreement containing provisions at least as favorable to Endwave as the confidentiality, standstill and nonsolicitation provisions of the Confidentiality Agreement (as defined in Section 5.03). In the event that Endwave shall determine to provide any information as described above, or shall receive any Endwave Acquisition Proposal (or any material amendment to an Endwave Acquisition Proposal previously received), it shall promptly, and in any event within 24 hours, inform GigOptix in writing as to that fact and shall furnish to GigOptix the identity of the recipient of such information to be provided and/or the Potential Acquirer and the terms of such Endwave Acquisition Proposal (or material amendment). For purposes of this Agreement, “Endwave Acquisition Proposal” shall mean any offer or proposal (other than an offer or proposal by GigOptix) relating to any Endwave Acquisition Transaction.

     (b) In addition to the obligations of Endwave set forth in Section 5.02(a), Endwave as promptly as practicable shall advise GigOptix orally and in writing of any Endwave Acquisition Proposal or any request for non-public information or inquiry which Endwave reasonably believes would lead to an Endwave Acquisition Proposal or to any Endwave Acquisition Transaction, the material terms and conditions of such Endwave Acquisition Proposal, request or inquiry, and the identity of the person or group making any such Endwave Acquisition Proposal, request or inquiry. Endwave will keep GigOptix informed as promptly as practicable in all material respects of the status and details (including material amendments or proposed material amendments) of any such Endwave Acquisition Proposal, request or inquiry.

     (c) From and after the Agreement Date until the Effective Time or termination of this Agreement pursuant to Article VIII, GigOptix and its Subsidiaries will not, nor will they authorize or permit any of their respective officers, directors, affiliates or employees or any investment banker, attorney or other advisor or representative retained by any of them to, directly or indirectly, (i) solicit, initiate, encourage or induce the making, submission or announcement of

65

any GigOptix Acquisition Proposal (as hereinafter defined), (ii) participate in any discussions or negotiations regarding, or furnish to any person any non-public information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any GigOptix Acquisition Proposal, (iii) engage in discussions with any person with respect to any GigOptix Acquisition Proposal, except as to the existence of these provisions, (iv) approve, endorse or recommend any GigOptix Acquisition Proposal or (v) enter into any letter of intent or similar document or any contract agreement or commitment contemplating or otherwise relating to any GigOptix Acquisition Transaction. For purposes of this Agreement, “GigOptix Acquisition Proposal” shall mean any offer or proposal (other than an offer or proposal by GigOptix) relating to any GigOptix Acquisition Transaction. For purposes of this Agreement, “GigOptix Acquisition Transaction” shall mean any transaction or series of related transactions involving: (A) any purchase from GigOptix or acquisition by any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a 30% interest in the total outstanding voting securities of GigOptix or any of its subsidiaries or any tender offer or exchange offer that if consummated would result in any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) beneficially owning 30% or more of the total outstanding voting securities of GigOptix or any of its subsidiaries or any merger, consolidation, business combination or similar transaction involving GigOptix; (B) any sale, lease (other than in the ordinary course of business), exchange, transfer, license (other than in the ordinary course of business), acquisition or disposition of more than 30% of the assets of GigOptix; or (C) any liquidation or dissolution of GigOptix.

     (d) Notwithstanding anything contained in Section 5.02(c), prior to the Effective Time, GigOptix may furnish nonpublic information regarding GigOptix to, and enter into discussions or negotiations with, any Person in response to an unsolicited, bona fide written GigOptix Acquisition Proposal made or received after the date of this Agreement, which GigOptix’s board of directors determines in good faith constitutes, or is reasonably likely to result in, a GigOptix Superior Offer (and is not withdrawn) if: (A) neither GigOptix nor any representative of GigOptix shall have failed to comply with this Section; (B) the board of directors of GigOptix concludes in good faith, after consultation with outside counsel, that the failure to take such action would result in a breach of the fiduciary duties of the board of directors of GigOptix under Applicable Law; (C) within 24 hours following the furnishing of any such nonpublic information to, or entering into discussions with, such Person, GigOptix gives Endwave written notice of the identity of such Person and of GigOptix’s intention to furnish nonpublic information to, or enter into discussions with, such Person or has furnished, or entered into discussions with, such Person. For purposes of this Agreement, “GigOptix Superior Offer” shall mean an unsolicited, bona fide written offer made by a third party to consummate any of the following transactions: (i) a merger or consolidation involving GigOptix pursuant to which the stockholders of GigOptix immediately preceding such transaction hold less than a majority of the equity interest in the surviving or resulting entity of such transaction or (ii) the acquisition by any person or group (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a cash-out merger

66

involving GigOptix), directly or indirectly, of ownership of 90% of the then outstanding shares of capital stock of GigOptix, on terms that the board of directors of GigOptix determines, in its reasonable judgment (based on the advice of counsel and the written advice of its financial advisor) to be an offer that the GigOptix board of directors must consider in order to fulfill its fiduciary duties; provided, however, that any such offer shall not be deemed to be an “GigOptix Superior Offer” if any financing required to consummate the transaction contemplated by such offer is not committed and is not likely in the reasonable judgment of GigOptix board of directors (based on the advice of its financial advisor) to be obtained by such third party on a timely basis.

     Section 5.03 Access to Information. From the Agreement Date until the Effective Time, Endwave and GigOptix will each afford to the other and their authorized representatives (including counsel, environmental and other consultants, accountants, auditors and agents) reasonable access during normal business hours and upon reasonable notice to all of its facilities, personnel and operations and to all of its and its Subsidiaries’ Books and Records, will permit the other and its authorized representatives to conduct inspections as they may reasonably request and will instruct its officers and those of its Subsidiaries to furnish such persons with such financial and operating data and other information with respect to its business and properties as they may from time to time reasonably request, subject to the restrictions set forth in the Confidentiality Agreement between GigOptix and Endwave (the “Confidentiality Agreement”). GigOptix and Merger Sub agree that each of them will treat any such information in accordance with the Confidentiality Agreement, which shall remain in full force and effect in accordance with its terms.

     Section 5.04 Special Meetings; Registration Statement; Board Recommendations.

     (a) Endwave Special Meeting. Promptly after the date hereof, subject to Section 5.04(c) and 5.04(e), Endwave will take all action necessary in accordance with Delaware Law and its Amended and Restated Certificate of Incorporation and bylaws to convene a meeting of Endwave Stockholders to consider adoption of this Agreement and approval of the Merger (the “Endwave Special Meeting”) to be held as promptly as practicable, and in any event (to the extent permissible under Applicable Law) within 45 days after the declaration of effectiveness of the Registration Statement. Subject to Section 5.04(c), Endwave will use its commercially reasonable efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and the approval of the Merger and will take all other action necessary or advisable to secure the vote or consent of its stockholders required by the rules of the NASDAQ Stock Market LLC (“NASDAQ”) or Delaware Law to obtain such approvals. Notwithstanding anything to the contrary contained in this Agreement, Endwave may adjourn or postpone the Endwave Special Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Proxy Statement is provided to Endwave’s stockholders in advance of a vote on the Merger and this Agreement or, if as of the time for which the Endwave Special Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of Endwave Common Stock represented (either in person or by proxy) to constitute a quorum

67

necessary to conduct the business of the Endwave Special Meeting. Endwave shall ensure that the Endwave Special Meeting is called, noticed, convened, held and conducted, and that all proxies solicited by Endwave in connection with the Endwave Special Meeting are solicited, in compliance with the Delaware Law, the Endwave Charter Documents, the rules of NASDAQ and all other applicable legal requirements.

     (b) Subject to Section 5.04(c): (i) the board of directors of Endwave shall unanimously recommend that Endwave’s stockholders vote in favor of and adopt and approve this Agreement and approve the Merger at the Endwave Special Meeting; (ii) the Proxy Statement shall include a statement to the effect that the board of directors of Endwave has unanimously recommended that Endwave’s stockholders vote in favor of and adopt and approve this Agreement and the Merger at the Endwave Special Meeting; and (iii) neither the board of directors of Endwave nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to GigOptix, the unanimous recommendation of the board of directors of Endwave that Endwave’s stockholders vote in favor of and adopt and approve this Agreement and the Merger. For purposes of this Agreement, said recommendation of the board of directors shall be deemed to have been modified in a manner adverse to GigOptix if said recommendation shall no longer be unanimous, provided that, for all purposes of this Agreement, an action by any board of directors or committee thereof shall be unanimous if each member of such board of directors or committee has approved such action other than (i) any such member who has appropriately abstained from voting on such matter because of an actual or potential conflict of interest and (ii) any such member who is unable to vote in connection with such action as a result of death or disability.

     (c) Nothing in this Agreement shall prevent the board of directors of Endwave from withholding, withdrawing, amending or modifying its unanimous recommendation in favor of the Merger if (i) an Endwave Superior Offer (as defined below) is made to Endwave and is not withdrawn, (ii) Endwave shall have provided written notice to GigOptix (a “Notice of Endwave Superior Offer”) advising GigOptix that Endwave has received an Endwave Superior Offer, specifying the material terms and conditions of such Endwave Superior Offer and identifying the person or entity making such Endwave Superior Offer, (iii) GigOptix shall not have, within five business days of GigOptix’s receipt of the Notice of Endwave Superior Offer, made an offer that the board of directors of Endwave by a majority vote determines in its good faith judgment (based on the written advice of its financial advisor) to be at least as favorable to Endwave’s stockholders as such Endwave Superior Offer (it being agreed that the board of directors Endwave shall convene a meeting to consider any such offer by GigOptix promptly following the receipt thereof), (iv) the board of directors of Endwave concludes in good faith, after consultation with its outside counsel, that, in light of such Endwave Superior Offer, the failure to withhold, withdraw, amend or modify such recommendation would be inconsistent with the fiduciary obligations of the board of directors of Endwave to Endwave’s stockholders under Applicable Law and (v) Endwave shall not have violated any of the restrictions set forth in Section 5.02 or this Section 5.04(c). Endwave shall provide GigOptix with at least three business days prior notice (or such lesser prior notice as provided to the members of Endwave’s board of directors but in no event less than twenty-four hours) of any meeting of Endwave’s

68

board of directors at which Endwave’s board of directors is reasonably expected to consider any Endwave Acquisition Transaction. For purposes of this Agreement, “Endwave Superior Offer” shall mean an unsolicited, bona fide written offer made by a third party to consummate any of the following transactions: (i) a merger or consolidation involving Endwave pursuant to which the stockholders of Endwave immediately preceding such transaction hold less than a majority of the equity interest in the surviving or resulting entity of such transaction or (ii) the acquisition by any person or group (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a cash-out merger involving Endwave), directly or indirectly, of ownership of 90% of the then outstanding shares of capital stock of Endwave, on terms that the board of directors of Endwave determines, in its reasonable judgment (based on the written advice of its financial advisor) to be more favorable to Endwave stockholders than the terms of the Merger; provided, however, that any such offer shall not be deemed to be an “Endwave Superior Offer” if any financing required to consummate the transaction contemplated by such offer is not committed and is not likely in the reasonable judgment of Endwave’s board of directors (based on the advice of its financial advisor) to be obtained by such third party on a timely basis.

     (d) Nothing contained in this Agreement shall prohibit Endwave or its board of directors from taking and disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2 promulgated under the Exchange Act.

     (e) As promptly as practicable after the execution of this Agreement, Endwave and GigOptix shall mutually prepare, and GigOptix shall file with the SEC, the Registration Statement including the preliminary Proxy Statement. Prior to the effectiveness of the Registration Statement: (a) Endwave shall execute and deliver to Cooley LLP and to Nixon Peabody LLP a tax representation letter in a customary form to be mutually agreed to by the parties; and (b) GigOptix and Merger Sub shall execute and deliver to Cooley LLP and Nixon Peabody LLP a tax representation letter in a customary form to be mutually agreed to by the parties. To the extent requested by GigOptix or Endwave, each of GigOptix, Merger Sub and Endwave shall confirm to Cooley LLP and to Nixon Peabody LLP the accuracy and completeness as of the Effective Time of the tax representation letters delivered pursuant to the immediately preceding sentence. Following the delivery of the tax representation letters pursuant to the second sentence of this Section 5.04(e): (a) GigOptix shall use commercially reasonable efforts to cause Nixon Peabody LLP to deliver to it a tax opinion satisfying the requirements of Item 601 of Regulation S-K under the Securities Act; and (b) Endwave shall use its reasonable best efforts to cause Cooley LLP to deliver to it a tax opinion satisfying the requirements of Item 601 of Regulation S-K under the Securities Act. In rendering such opinions, each of such counsel shall be entitled to rely on the tax representation letters referred to in this Section 5.04(e). GigOptix and Endwave shall use all commercially reasonable efforts to have the preliminary Proxy Statement cleared by the SEC and the Registration Statement declared effective by the SEC as promptly as practicable. As promptly as practicable following receipt of SEC comments on such Registration Statement and preliminary Proxy Statement, GigOptix and Endwave shall mutually prepare a response to such comments. Upon resolution of all comments, GigOptix shall file the Registration Statement with the SEC, in which the Proxy

69

Statement will be included, as a prospectus. GigOptix shall also take any action required to be taken under applicable state blue sky or securities laws in connection with GigOptix Common Stock to be issued in exchange for the shares of Endwave Common Stock. GigOptix and Endwave shall promptly furnish to each other all information, and take such other actions (including without limitation using all commercially reasonable efforts to provide any required consents of their respective independent auditors), as may reasonably be requested in connection with any action by any of them in connection with the preceding sentences of this Section 5.04(e). Whenever any party learns of the occurrence of any event which is required to be set forth in an amendment or supplement to the Proxy Statement, the Registration Statement or any other filing made pursuant to this Section 5.04(e), GigOptix or Endwave, as the case may be, shall promptly inform the other of such occurrence and cooperate in filing with the SEC or its staff and/or mailing to stockholders of Endwave such amendment or supplement.

     (f) As promptly as practical after the execution of this Agreement, GigOptix shall prepare and make such filings as are required under applicable blue sky laws for the purpose of obtaining necessary permits and qualifications (to the extent that exemptions from the need to obtain such permits or qualifications are not available) in connection with the issuance of GigOptix Common Stock in the Merger or pursuant to Section 2.02 in such jurisdictions for which Endwave and GigOptix determine such filings are required to be made. Endwave shall provide promptly all information in its possession that is reasonably requested by GigOptix for the purpose of compliance with this Section 5.04(f).

     Section 5.05 Commercially Reasonable Efforts.

     (a) Subject to the terms and conditions herein provided, GigOptix, Merger Sub and Endwave shall use commercially reasonable efforts to take, or cause to be taken, all actions and do, or cause to be done, all things necessary, proper or appropriate under this Agreement, Applicable Laws to consummate and make effective the transactions contemplated by this Agreement, including, without limitation, (i) using commercially reasonable efforts to obtain all necessary governmental and private party consents, approvals or waivers, and (iii) using commercially reasonable efforts to lift any legal bar to the Merger. GigOptix shall cause Merger Sub to perform all of its obligations under this Agreement. Without limiting the foregoing, in the event that any submission is required under the Antitrust Laws, GigOptix Merger Sub, and Endwave will as soon as reasonably practicable after the date of this Agreement and in no event later than 10 business days after the date of this Agreement, for any obligations triggered by the HSR Act, and in no event later than 15 business days, for any obligations triggered by any of the other Antitrust Laws, file or cause to be filed all notices, reports and other documents required to be filed by such party with any Governmental Authority with respect to the transactions contemplated by this Agreement to initiate the approval process. Each of GigOptix, Merger Sub and Endwave shall promptly (1) supply the other party with any information that may be required in order to effectuate notices, reports, documents or other filings with any Governmental Authority required to be made pursuant to any Antitrust Laws, (2) supply any additional information which reasonably may be required by any Governmental Authority in connection with any submission required under the Antitrust Laws, and (3) promptly inform the

70

other party of the substance of any communication to or from any Governmental Authority regarding the transactions contemplated by this Agreement.

     (b) Notwithstanding anything to the contrary in this Agreement, neither GigOptix, nor the Surviving Corporation, nor any of their Subsidiaries shall be required to (i) divest, hold separate or license any business(es), product line(s) or asset(s), (ii) take any action or accept any limitation that would reasonably be expected to have a GigOptix Material Adverse Effect or an Endwave Material Adverse Effect, or (iii) agree to any of the foregoing.

     Section 5.06 Public Announcements. Before issuing any press release or otherwise making any public statement with respect to the Merger or any of the other transactions contemplated hereby, GigOptix, Merger Sub and Endwave agree to consult with each other as to its form and substance, and agree not to issue any such press release or general communication to employees or make any public statement prior to obtaining the consent of the other (which shall not be unreasonably withheld, conditioned or delayed), except as may be required by Applicable Law or by the rules and regulations of or listing agreement with NASDAQ or as may otherwise be required by NASDAQ or the SEC.

     Section 5.07 Notification of Certain Matters. Each of Endwave and GigOptix shall promptly notify the other party of the occurrence or non-occurrence of any event the respective occurrence or non-occurrence of which would be reasonably likely to cause any condition to the obligations of the notifying party to effect the Merger not to be fulfilled. Each of Endwave and GigOptix shall also give prompt notice to the other of any communication from any Person alleging that the consent of such Person is or may be required in connection with the Merger or other transactions contemplated hereby.

     Section 5.08 NYSE AMEX Listing. GigOptix shall use commercially reasonable efforts to cause the GigOptix Common Stock issuable pursuant to Section 2.01 to be authorized for listing on the NYSE AMEX, subject to official notice of issuance, prior to the Closing Date, and if that is not reasonably possible, then as soon thereafter as is reasonably possible. If within 60 days following the Effective Time, such shares of GigOptix Common Stock has not been so authorized, then the board of directors of GigOptix will use its best efforts to take further actions as appropriate to achieve such listing on NYSE AMEX, subject to official notice of issuance.

     Section 5.09 Resignation of Directors and Officers. Prior to the Effective Time, Endwave shall deliver to GigOptix at no cost the resignations of such directors and officers of Endwave and its Subsidiaries as GigOptix shall specify at least ten business days prior to the Closing, effective at the Effective Time.

     Section 5.10 Appointment of New GigOptix Directors. The board of directors of GigOptix shall take such action as deemed necessary to elect Joseph Lazzara and John Mikulsky as new members of the such board of directors, with terms expiring in 2012 and 2013, respectively. Not later than each such director’s appointment to the board of directors, GigOptix will enter into an indemnity agreement with each director in the same form as then exists

71

between GigOptix and each of its other directors. Such directors shall be entitled to the same compensation as all other GigOptix non-employee directors.

     Section 5.11 Directors’ and Officers’ Indemnification and Insurance.

     (a) GigOptix shall, or shall cause the Surviving Corporation to, fulfill and honor the obligation of Endwave to Endwave’s present and former directors and officers (the “Indemnified Directors and Officers”) pursuant to the terms of Endwave’s Amended and Restated Certificate of Incorporation and bylaws.

     (b) Notwithstanding anything else set forth in this Agreement, (i) this Section 5.11 shall survive the consummation of the Merger, (ii) is intended to benefit the Indemnified Directors and Officers and their respective heirs and (iii) is in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have against GigOptix or the Surviving Corporation first arising after the Closing Date by contract or otherwise. This Section 5.11 shall not be terminated or modified in such a manner as to adversely affect the rights of any Indemnified Director and Officer under this Section 5.11 without the written consent of such affected Indemnified Director and Officer.

     (c) From the Effective Time until the sixth anniversary of the Effective Time, neither GigOptix nor the Surviving Corporation shall take any action to terminate any liability insurance that Endwave acquires and fully pays for prior to the Effective Time with respect to claims arising against Endwave’s officers and directors with respect to their acts and omissions as directors and officers of Endwave occurring prior to the Effective Time (the “Tail Policy”); provided that the Surviving Corporation may, but under no circumstances shall be obligated to, substitute a policy of at least the same coverage containing terms and conditions that, in the aggregate, are no less advantageous. Endwave shall purchase the Tail Policy, which for clarity, would constitute a Merger Expense.

     Section 5.12 Consents of GigOptix’s and Endwave’s Accountants. Each of GigOptix and Endwave shall use commercially reasonable efforts to cause its independent accountants to deliver to GigOptix a consent, dated the date on which the Registration Statement shall become effective, in form reasonably satisfactory to GigOptix and customary in scope and substance for consents delivered by independent public accountants in connection with registration statements on Form S-4 under the Securities Act.

     Section 5.13 Notification of Certain Matters. Endwave shall give prompt notice to GigOptix and Merger Sub, and GigOptix and Merger Sub shall give prompt notice to Endwave, of (i) the occurrence or nonoccurrence of any event the occurrence or nonoccurrence of which would be likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate such that the condition in Section 7.01(a) or 7.02(a), as applicable, would not be satisfied, (ii) any material failure of the Endwave, GigOptix or Merger Sub, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder such that the condition in Section 7.01(b) or 7.02(b), as applicable, would not be satisfied, (iii) any notice or other communication from any third party alleging that the consent of

72

such third party is or may be required in connection with the transactions contemplated by this Agreement, or (iv) any facts or circumstances that arise that could reasonably be expected to result in an Endwave Material Adverse Effect or a GigOptix Material Adverse Effect, as the case may be.

     Section 5.14 SEC Filings.

     (a) Endwave will deliver promptly to GigOptix true and complete copies of each report, registration statement or statement mailed by it to its security holders generally or filed by it with the SEC, in each case subsequent to the Agreement Date and prior to the Effective Time. As of their respective dates, such reports, including the consolidated financial statements included therein, and statements (excluding any information therein provided by GigOptix or Merger Sub, as to which Endwave makes no representation) will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading and will comply in all material respects with all applicable requirements of law. Each of the consolidated financial statements (including, in each case, any related notes hereto) contained in such reports, (x) shall comply as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto, (y) shall be prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited interim financial statements, as may be permitted by the SEC on Form 10-Q under the Exchange Act) and (z) shall fairly present the consolidated financial position of Endwave and its Subsidiaries as at the respective dates thereof and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim financial statements were or are subject to normal and recurring year-end adjustments which were not, or are not expected to be, material in amount.

     (b) GigOptix will deliver promptly to Endwave true and complete copies of each report, registration statement or statement mailed by it to its security holders generally or filed by it with the SEC, in each case subsequent to the Agreement Date and prior to the Effective Time. As of their respective dates, such reports, including the consolidated financial statements included therein, and statements (excluding any information therein provided by Endwave, as to which GigOptix makes no representation) will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading and will comply in all material respects with all applicable requirements of law. Each of the consolidated financial statements (including, in each case, any related notes hereto) contained in such reports, (x) shall comply as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto, (y) shall be prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited interim financial statements, as may be permitted by the SEC on Form 10-Q under the Exchange Act) and (z) shall fairly present the consolidated financial position of GigOptix and its Subsidiaries as at the respective dates

73

thereof and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim financial statements were or are subject to normal and recurring year-end adjustments which were not, or are not expected to be, material in amount.

     Section 5.15 Employees. Endwave, prior to the Closing, and Surviving Corporation, immediately after the Effective Time and for such period of time as it determines in its sole discretion, shall continue the at-will employment of Endwave’s employees who remain employed by Endwave or its Subsidiaries at the Effective Time (the “Continuing Employees”) on terms and conditions commensurate with similarly situated employees of GigOptix or GigOptix’s Affiliates. Prior to the Effective Time, GigOptix shall make written offers of such employment terms and conditions, on behalf of the Surviving Corporation, to each Continuing Employee. Continuing Employees who are employed by the Surviving Corporation shall receive credit for service with Endwave and its Subsidiaries (including credit with predecessors recognized by Endwave and its Subsidiaries) for purposes of earning and accruing paid time off. Endwave shall, upon the request of GigOptix, take all required corporate action to terminate Endwave’s 401(k) plan, effective immediately prior to the Effective Time but contingent thereon. Endwave shall take all required corporate action to terminate all other Endwave Benefit Arrangements which it may terminate under Applicable Law and without the consent of any participants under such Endwave Benefit Arrangement, effective immediately prior to the Effective Time but contingent thereon.

     Section 5.16 Endwave International Company Limited. Endwave shall cause John Mikulsky and Dan Teuthorn upon the Effective Time to transfer the two shares of stock of Endwave International Company Limited, an Endwave subsidiary and a corporation registered under the laws of Thailand, to GigOptix and to Lumera Corporation, respectively.

     (a) by mutual written consent duly authorized by the boards of directors of GigOptix and Endwave;

     (b) by either Endwave or GigOptix if the Merger shall not have been consummated by June 30, 2011 (the “End Date”) for any reason; provided, however, that the right to terminate this Agreement under this Section 8.01(b) shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Merger to occur on or before such date and such action or failure to act constitutes a material breach of a covenant of such party set forth in this Agreement;

     (d) by Endwave or GigOptix if the Stockholder Approval shall not have been obtained by reason of the failure to hold a meeting or the failure to obtain the required vote at a meeting of Endwave stockholders duly convened therefor or at any adjournment thereof; provided, however, that the right to terminate this Agreement under this Section 8.01(d) shall not be available to Endwave where the failure to hold a meeting or the failure to obtain Stockholder Approval shall have been caused by the action or failure to act of Endwave (other than in compliance with Section 5.04(c)) and such action or failure to act constitutes a material breach by Endwave of its covenants set forth in this Agreement.

     (e) by GigOptix or Endwave (at any time prior to the Effective Time) if an Endwave Triggering Event (as defined below) shall have occurred;

     (f) by Endwave, upon a breach of any representation, warranty, covenant or agreement on the part of GigOptix set forth in this Agreement, or if any representation or warranty of GigOptix shall have become untrue, in either case such that the conditions set forth in Section 7.01(a) or Section 7.01(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that such inaccuracy in GigOptix’s representations and warranties or breach by GigOptix remains uncured on the date which is twenty business days following written notice of such breach or inaccuracy from Endwave to GigOptix (it being understood that Endwave may not terminate this Agreement pursuant to this paragraph (f) if it shall have materially breached any of its covenants in this Agreement and remains in breach of such covenants as of the date of such termination);

     (g) by GigOptix, upon a breach of any representation, warranty, covenant or agreement on the part of Endwave set forth in this Agreement, or if any representation or

77

warranty of Endwave shall have become untrue, in either case such that the conditions set forth in Section 7.02(a) or Section 7.02(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that such inaccuracy in Endwave’s representations and warranties or breach by Endwave remains uncured on the date which is twenty business days following written notice of such breach or inaccuracy from GigOptix to Endwave (it being understood that GigOptix may not terminate this Agreement pursuant to this paragraph (g) if it shall have materially breached any of its covenants in this Agreement and remains in breach of such covenants as of the date of such termination);

For the purposes of this Agreement, an “Endwave Triggering Event” shall be deemed to have occurred if: (i) the board of directors of Endwave or any committee thereof shall for any reason have withdrawn or shall have amended or modified in a manner adverse to GigOptix its recommendation in favor of, the adoption and approval of the Agreement or the approval of the Merger; (ii) Endwave shall have failed to include in the Proxy Statement the recommendation of the board of directors of Endwave in favor of the adoption and approval of the Agreement and the approval of the Merger; (iii) the board of directors of Endwave fails to reaffirm its recommendation in favor of the adoption and approval of the Agreement and the approval of the Merger within ten days after GigOptix requests in writing that such recommendation be reaffirmed at any time following the public announcement of an Endwave Acquisition Proposal; (iv) the board of directors of Endwave or any committee thereof shall have approved or recommended any Endwave Acquisition Proposal; or (v) a tender or exchange offer relating to securities of Endwave shall have been commenced by a Person unaffiliated with GigOptix and Endwave shall not have sent to its security holders pursuant to Rule 14e-2 promulgated under the Securities Act, within ten business days after such tender or exchange offer is first published, sent or given, a statement disclosing that Endwave recommends rejection of such tender or exchange offer.

     Section 8.02 Notice of Termination; Effect of Termination. Any termination of this Agreement under Section 8.01 will be effective immediately upon the delivery of a valid written notice of the terminating party to the other parties hereto.

     Section 8.03 Fees and Expenses.

     (a) General. Except as set forth in this Section 8.03, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses whether or not the Merger is consummated; provided, however, that GigOptix and Endwave shall share equally all fees and expenses, other than attorneys’ and accountants’ fees and expenses, incurred in relation to the printing and filing (with the SEC) of

78

the Proxy Statement (including any preliminary materials related thereto) and the Registration Statement (including financial statements and exhibits) and any amendments or supplements thereto.

     (b) Endwave Payments. In the event that this Agreement is terminated by GigOptix or Endwave pursuant to Section 8.01(e), Endwave shall promptly, but in no event later than two days after the date of such termination, pay GigOptix a fee equal to $1,000,000, plus all reasonable documented expenses incurred by GigOptix in connection with this Agreement and the transactions contemplated hereby, in immediately available funds (the “Termination Fee”). Endwave acknowledges that the agreements contained in this Section 8.03(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, GigOptix would not enter into this Agreement; accordingly, if Endwave fails to pay in a timely manner the amounts due pursuant to this Section 8.03(b) , and, in order to obtain such payment, GigOptix makes a claim that results in a judgment against Endwave for the amounts set forth in this Section 8.03(b), Endwave shall pay to GigOptix its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts set forth in this Section 8.03(b) at the prime rate of interest that under current practice is listed as such under the heading “Money Rates” in the Eastern Edition of The Wall Street Journal on the date such payment was required to be made. Payment of the fees described in this Section 8.03(b) shall be credited toward any damages payable by Endwave in the event of breach of this Agreement.

Exhibit 99.1

GigOptix, Inc. To Acquire Endwave Corporation

The Leader in Optical High Speed and the Leader in High Frequency RF Electronics to Combine

GigOptix and Endwave Also Provide Preliminary Financial Results for Fourth Quarter and 2010

Palo Alto, CA (February 7, 2011) GigOptix, Inc. (OTCBB: GGOX), a leading supplier of high performance electronic and electro-optic components that enable next generation 40G and 100G optical networks, today announced that it has signed a definitive merger agreement to acquire Endwave Corporation (NASDAQ: ENWV), a leading provider of high frequency RF solutions and semiconductor products for the wireless mobile backhaul communications, satellite communications, electronic instruments and defense and security markets. The combined company will retain the name GigOptix, Inc. to become a high speed, high frequency leader for optical and wireless communications. The acquisition is expected to close in the second quarter of this year.

“I am very excited about the strategic merger of GigOptix and Endwave. Once complete, the combined company will be well positioned to be a leader in high speed communication components. We are set to offer solutions to both the optical and microwave RF front ends that will drive continued growth and bring added value to our customers and stockholders,” commented Dr. Avi Katz, GigOptix’s Chairman of the Board of Directors and Chief Executive Officer. “Responding to the core issue of increasing bandwidth to meet customer demand has shaped the technology advancements for both companies. By combining Endwave’s extensive point to point microwave radio system knowledge and Monolithic Microwave IC (MMIC) product portfolio with GigOptix’s portfolio of optical modulators and broadband amplifiers, it positions us to not only expand our market opportunities, but also enables us to increase our penetration of the existing customer bases and market segments. The combined company will be able to leverage Endwave’s manufacturing and GigOptix’s high speed fiber optic front end technology to provide cutting-edge solutions for next generation 100G and 400G drivers and electro-optic sub-systems.”

Merger Highlights:

The merger will enable the combined company to:

• Address customers’ growing needs for high speed solutions in both wireless mobile backhaul and optical networks by providing a one-stop-shop with a comprehensive solution portfolio to consolidate and simplify supply chains;

• Strengthen its financial performance with estimated post-merger consolidated cash of about $16 million after payment of closing expenses and severance, as well as enhance revenue and deliver operational cost savings beginning in 2011, reaching approximately $1 million per quarter in 2012;

• Strengthen the combined company’s high speed design capabilities in both point to point radio and optical networks while providing advanced and low cost assembly, testing and production through Endwave’s facility in Thailand;

• Leverage GigOptix’s high speed broadband ICs, mixed signal technologies, and Thin Film Polymer on Silicon (TFPS™) technology and Endwave’s MLMS™ system-on-chip technology to further increase the level of integration of electro-optical front ends;

• Develop electro-optical systems-on-a-chip such as integrated drivers and modulators; electro-optical transceivers on a chip; and microwave photonic transceivers for base stations;

• Consolidate GigOptix’s microwave products with Endwave’s MMIC product line for commercial and military applications with the potential for expansion into the high speed instrumentation market;

• Strengthen the combined company’s IC design capabilities in both GaAs and SiGe manufacturing processes, which will enable additional integration, functionality and cost reductions for products targeting microwave/millimeter wave and broadband fiber optic applications; and

• Strengthen the company’s 40G, 100G and next generation 400G Surface Mount Technology (SMT) packaging capabilities by leveraging Endwave’s expertise in millimeter wave SMD packaging.

“The acquisition of Endwave, an acknowledged leader in high frequency point to point radio communication systems, confirms GigOptix’s continuous commitment to support new generation communication networks,” added Andrea Betti-Berutto, GigOptix’s Chief Technology Officer. “In addition to the many technical synergies between high speed RF microwave and millimeter wave radio and fiber optic network electronic designs, we see exciting growth opportunities for wireless mobile backhaul to build out the broadband communication infrastructure. Driven by increasing use of bandwidth intensive smartphones and services, the same market demands that force network operators to upgrade their optical equipment from 10Gb/s to 40Gb/s and 100Gb/s and next generation 400Gb/s, force operators to upgrade their mobile backhaul equipment to higher frequencies into the 71 to 95GHz E-band to support the increased bandwidth generated from cellular networks.”

“We have a proven track record of successfully integrating acquisitions. As with all transactions based upon our initial 2007 Strategic Plan of inorganic and organic growth, this merger with Endwave is the next step in our long-term vision of building the industry’s premier supplier of front end solutions for high speed optical and microwave RF communication links, based on solid financial foundations,” said Dr. Avi Katz. “We look forward to furthering our leadership position as the only pure play provider of electronic devices for high-speed fiber-optic and wireless communications covering all applications, all speeds and all distances. Adding Endwave’s products and manufacturing capabilities to the GigOptix catalog will further simplify our customers’ supply chain as we become the one-stop shop for solutions that address the demands of both the optical core and the mobile backhaul networks. The combined company will have a strong balance sheet with about $16 million of cash, a significant revenue base and together with the optimization of the sales, marketing, and operations teams we have a clear short term path to profitability.”

Commenting on the merger, Mr. John Mikulsky, Endwave’s President and Chief Executive Officer stated, “The merger of Endwave and GigOptix is an ideal combination of technology, opportunity and vision. As a combined company, I believe we can effectively build upon our technology leadership and success for a strong and exciting future. Together, we can deliver the most extensive and comprehensive product portfolio in the industry, providing customers with the highest quality yet cost-effective technology solutions. The Endwave team and I look forward to working with Dr. Katz and his team to achieve the next generation of success for the combined company.”

Terms of the Transaction:

Under the terms of the merger agreement, all outstanding shares of Endwave common stock, including those issuable upon settlement of outstanding restricted stock units, and outstanding in-the-money Endwave stock options, will be converted into shares of GigOptix common stock such that immediately after the merger, such shares represent approximately 42.5% of all outstanding GigOptix common stock. Based on the number of shares of Endwave and GigOptix common stock outstanding as of January 31, 2011, approximately 9.1 million shares of GigOptix common stock will be issued to holders of Endwave common stock, registered stock units and stock options. The issuance of shares will be made pursuant to an effective Registration

Statement on Form S-4 to be filed shortly with the Securities and Exchange Commission. GigOptix will continue its best efforts to list GigOptix common stock on NYSE Amex or another national securities exchange.

The transaction is subject to customary closing conditions and regulatory approvals, as well as the approval of the merger by Endwave’s stockholders. The merger is expected to close during the second quarter of 2011.

A PowerPoint presentation has been posted on the Web site of both companies, detailing the transaction rationale, motivation and prospects of the merger between GigOptix and Endwave.

Key Management and Board of Directors

Dr. Katz will maintain his positions as Chairman of the Board of Directors, Chief Executive Officer and President of the combined company. Curt P. Sacks, the current Chief Financial Officer of Endwave, will serve as the Chief Financial Officer of the combined company. Andrea Betti-Berutto, the current Chief Technology Officer of GigOptix, will serve as the Chief Technology Officer of the combined company. Other key executives from both companies

will serve on the management team. GigOptix’s new Board of Directors will consist of all five existing GigOptix directors and two directors that will be recommended by the Endwave Board of Directors, subject to the approval of the GigOptix Chairman of the Board, one of which will be Mr. Mikulsky.
