Item 4. Purpose of Transaction

On January 30, 2017, the Reporting Person entered into an Agreement and Plan of Merger (the “Merger Agreement”) with the Issuer, pursuant to which the Reporting Person would acquire all of the outstanding equity interests of the Issuer. Under the terms and subject to the conditions set forth in the Merger Agreement, a wholly-owned subsidiary of the Reporting Person (“Merger Sub”) will be formed and will merge with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as a wholly-owned subsidiary of the Reporting Person (the “Surviving Corporation”). As of the effective time of the Merger (the “Effective Time”), each outstanding share of Common Stock (other than shares owned by the Issuer or the Reporting Person or any of its subsidiaries (including Merger Sub), which shall be cancelled, and any Dissenting Shares (as defined in the Merger Agreement)), will be converted automatically into the right to receive $19.65 in cash, without interest (the “Merger Consideration”), subject to any applicable tax withholdings.

As of the Effective Time, any outstanding and unexercised stock options of the Issuer with an exercise price below the Merger Consideration, whether or not vested, will be converted into the right to receive a cash payment equal to the Merger Consideration minus the exercise prices of such options for each share of Common Stock underlying such options, and stock options with an exercise price above the Merger Consideration will be cancelled. Any outstanding restricted stock units of the Issuer, whether or not vested, will be converted into the right to receive a cash payment equal to the Merger Consideration for each share of Common Stock underlying such restricted stock units. Prior to the Effective Time (or, if earlier, the last day of the current purchase period under the Issuer’s employee stock purchase plan (the “ESPP”)), any amounts credited to the accounts of participants in the Issuer’s ESPP will be used to purchase shares of Common Stock, and each such share shall then be converted into the right to receive a cash payment equal to the Merger Consideration. The payments described in this paragraph will be subject to any applicable tax withholdings.

Each of the Reporting Person’s, Merger Sub’s and the Issuer’s obligation to consummate the Merger is subject to a number of conditions specified in the Merger Agreement, including (1) the approval of the Merger Agreement and the principal terms of the Merger by the affirmative vote of the holders of a majority of total number of shares of Common Stock outstanding, (2) the receipt of certain required regulatory approvals, (3) the absence of an order, judgment, injunction or law prohibiting the consummation of the Merger, (4) the accuracy of the other party’s representations and warranties contained in the Merger Agreement (subject to certain materiality standards set forth in the Merger Agreement) and (5) the other party’s compliance with or performance of its pre-closing covenants and agreements contained in the Merger Agreement in all material respects.

The description of the Merger Agreement included in this Item 4 is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is incorporated herein by reference under Exhibit 1 hereto.

In connection with the Merger Agreement, Errol Ginsberg, the Errol Ginsberg and Annette R. Michelson Family Trust dated October 13, 1999, Laurent Asscher and Katelia Capital Group, Ltd. (together, the “Shareholders”), in their capacity as shareholders of the Issuer, entered into voting and support agreements (each, a “Voting and Support Agreement”) with the Reporting Person and the Issuer. Pursuant to the Voting and Support Agreements and as more fully described therein, each Shareholder, among other things, has agreed (a) that at any meeting (whether annual or special and each adjourned or postposed meeting) of Issuer’s shareholders, however called, or in connection with any written consent of Issuer’s shareholders, such Shareholder will (i) appear at such meeting or otherwise cause all of the shares of Common Stock which such Shareholder beneficially owns as of the applicable record date (the “Subject Shares”), to be counted as present at the meeting for purposes of calculating a quorum and (ii) vote or cause to be voted (including by proxy or written consent, if applicable) all Subject Shares, among other things, (A) in favor of the approval of the Merger Agreement and the principal terms of the Merger,

Page 5 of 9

(B) in favor of any proposal to adjourn or postpone such meeting of the Issuer’s shareholders to a later date if such adjournment or postponement is done in accordance with the terms in the Voting and Support Agreement, (C) against any action, proposal, transaction or agreement in favor of an Acquisition Proposal (as defined in the Merger Agreement), without regard to the terms of such Acquisition Proposal, and (D) against any action, proposal, transaction or agreement that is intended to or would prevent, materially impede, materially delay or otherwise materially and adversely affect the Issuer’s, the Reporting Person’s or Merger Sub’s ability to timely consummate the transactions contemplated by the Merger Agreement, including the Merger, (b) that such Shareholder shall not, and shall cause each of its Affiliates (as defined in the Merger Agreement) and its and their respective directors, officers or employees not to, and shall use his or her reasonable best efforts to cause its and their other Representatives (as defined in the Merger Agreement) not to, directly or indirectly solicit, initiate, knowingly encourage or knowingly facilitate any Acquisition Proposal and (c) to certain transfer restrictions with respect to the Subject Shares, in each case subject to the terms and conditions contained therein. The Voting and Support Agreements will terminate upon the earliest to occur of (i) the consummation of the Merger, (ii) the termination of the Merger Agreement pursuant to and in compliance with the terms therein, (iii) the Issuer’s board of directors effecting a Company Adverse Recommendation Change (as defined in the Merger Agreement) and (iv) the entry without the prior written consent of the Shareholders into any amendment or modification of the Merger Agreement, or any written waiver of the Issuer’s rights under the Merger Agreement made in connection with a request from the Reporting Person, in each case, which results in a decrease in, or change in the composition of, the Merger Consideration payable to any shareholder.

The Reporting Person did not pay any additional consideration to the Shareholders in connection with the execution and delivery of the Voting and Support Agreements. The purpose of the Voting and Support Agreements is to increase the likelihood that the Merger will be consummated.

The description of the Voting and Support Agreements included in this Item 4 is qualified in its entirety by reference to the full text of each of the Voting and Support Agreements, copies of which are incorporated herein by reference under Exhibit 2 and Exhibit 3 hereto.

From and after the completion of the Merger, (i) the directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, and (ii) the individuals appointed by the Reporting Person prior to or as of the Effective Time shall be the officers of the Surviving Corporation. In addition, upon completion of the Merger, subject to the requirements of Section 5.06 of the Merger Agreement, the articles of incorporation and by-laws of the Surviving Corporation will be amended and restated to be the articles of incorporation and by-laws of Merger Sub in effect immediately prior to the Effective Time (except with respect to the name of the Surviving Corporation, which shall be “Ixia”).

Upon the consummation of the Merger, the shares of Common Stock will become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act, and the Reporting Person will cause them to be deregistered. In addition, the Reporting Person will cause the shares of Common Stock to be delisted from the NASDAQ Global Select Market.

Other than as described in this Item 4, the Reporting Person currently has no plans or proposals that relate to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D. The Reporting Person intends to continue to review the Issuer and its assets, corporate structure, dividend policy, capitalization, operations, properties, policies, management and personnel, and to further consider, following the consummation of the Merger and the appointment of directors to the Issuer’s board of directors, whether any changes would be desirable in light of the circumstances then existing, and reserves the right to take such actions or effect such changes as it deems desirable.

Such 18,053,853 shares of Common Stock represent approximately 21.8% of the outstanding shares of Common Stock as of January 26, 2017 based upon 82,649,261 shares of Common Stock outstanding as of such date (as represented by the Issuer in the Merger Agreement).

Including Subject Shares that the Shareholders may subsequently receive due to the Shareholders’ exercise of options or vesting of restricted stock units within 60 days of the date of this Schedule 13D, as a result of the execution of the Voting and Support Agreements, as of January 30, 2017, the Reporting Person may be deemed to have acquired beneficial ownership of 18,783,066 shares of Common Stock, which are either owned directly by the Shareholders or over which the Shareholders have the power to vote or dispose.

Other than the Subject Shares, which may be deemed to be beneficially owned by the Reporting Person as a result of the execution of the Voting and Support Agreements, the Reporting Person does not beneficially own any other shares of Common Stock, and, to the knowledge of the Reporting Person, none of the persons listed on Schedule A hereto beneficially own any shares of Common Stock.

The Reporting Person hereby disclaims that it constitutes a “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with the Shareholders and, pursuant to Rule 13d-4 under the Exchange Act, hereby disclaims beneficial ownership of any shares of Common Stock beneficially owned by the Shareholders or any of their affiliates including, without limitation, the Subject Shares.

The Reporting Person may also be deemed to share with the Shareholders the power to dispose, or direct the disposition, of the Subject Shares solely to the extent the Voting and Support Agreement restricts the ability of the Shareholders to transfer the Subject Shares, as more fully described in Item 4 of this statement and in the Voting and Support Agreements.

The Reporting Person hereby disclaims that it constitutes a “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with the Shareholders and, pursuant to Rule 13d-4 under the Exchange Act, hereby disclaims beneficial ownership of any shares of Common Stock beneficially owned by the Shareholders or any of their affiliates including, without limitation, the Subject Shares.
