CALCULATION OF FILING FEE

Transaction valuation*	Amount of filing fee**
$230,873,760.02	$26,758.27

* Estimated solely for purposes of calculating the filing fee. The transaction value was determined by adding (i) 67,641,585, the number of outstanding shares of GigPeak, Inc. common stock, multiplied by $3.08, the offer price, (ii) 6,894,399, the number of shares of common stock issuable pursuant to outstanding options with an exercise price less than the offer price of $3.08 per share, multiplied by $0.82, which is the offer price of $3.08 minus the weighted average exercise price for such options of $2.26 per share, (iii) 5,470,038 shares of common stock underlying restricted stock units, multiplied by the offer price of $3.08 per share, and (iv) 36,554, the number of shares of common stock issuable pursuant to the exercise of outstanding warrants with an exercise price less than the offer price of $3.08 per share, multiplied by $1.00, which is the offer price of $3.08 minus the weighted average exercise price for such warrants of $2.08 per share. The foregoing share figures have been provided by the issuer to the offerors and are as of March 1, 2017, the most recent practicable date.

** The filing fee was calculated in accordance with Rule 0-11 under the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory No. 1 for Fiscal Year 2017, issued August 31, 2016, by multiplying the transaction value by 0.0001159.

This Amendment No. 1 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO (the “Schedule TO”), filed with the United States Securities and Exchange Commission on March 7, 2017 by Glider Merger Sub, Inc. (the “Purchaser”), a Delaware corporation and a wholly owned subsidiary of Integrated Device Technology, Inc. (“IDT”) and IDT, a Delaware corporation. The Schedule TO relates to the offer by Purchaser to purchase all of the outstanding shares of common stock, par value $0.001 per share of GigPeak, Inc. (“GigPeak”), a Delaware corporation, including the associated purchase rights for Series A Junior Preferred Stock of GigPeak (the “Rights”) issued under the Rights Agreement, dated as of December 16, 2014, as amended, between GigPeak and American Stock Transfer & Trust Company, LLC, as rights agent (such Rights, together with the common stock, the “Shares”), at a price of $3.08 per Share, in cash, without interest and subject to any applicable withholding of taxes, upon the terms and subject to the conditions described in the Offer to Purchase, dated March 7, 2017 (as it may be amended or supplemented from time to time, the “Offer to Purchase”), and in the related letter of transmittal (as it may be amended or supplemented from time to time, the “Letter of Transmittal”), copies of which are attached hereto as Exhibits (a)(1)(i) and (a)(1)(ii), respectively, which Offer to Purchase and Letter of Transmittal collectively constitute the “Offer.”

The information in the Offer to Purchase and the Letter of Transmittal is incorporated in this Amendment by reference to all of the applicable items in the Schedule TO, except that such information is amended and supplemented to the extent specifically provided in this Amendment. Capitalized terms used and not otherwise defined in this Amendment shall have the meanings assigned to such terms in the Offer to Purchase or in the Schedule TO.

The items of the Schedule TO set forth below are hereby amended and supplemented as follows:

Item 11. Additional Information

Section 17 — “Certain Legal Matters; Regulatory Approvals — Litigation” of the Offer to Purchase is hereby amended and supplemented by adding the following paragraphs immediately after the last paragraph of such subsection:

On February 17, 2017, a purported stockholder class action complaint was filed in the Superior Court of the State of California in and for the County of Santa Clara against GigPeak, the members of the board of directors of GigPeak, as well as against IDT and Purchaser, captioned Carbajal v. GigPeak Inc., et al., Case No. 17CV306571 (the “California State Action”). The complaint alleges that the members of GigPeak’s board of directors breached their fiduciary duties of loyalty, good faith, due care and disclosure by, inter alia, (i) agreeing to sell GigPeak without first taking steps to ensure that Plaintiff and all the other public shareholders of GigPeak would obtain adequate, fair and maximum consideration under the circumstances and (ii) engineering the Offer and the Merger Agreement to benefit themselves and/or IDT without regard for the public shareholders of GigPeak, and alleges that GigPeak, IDT and Purchaser aided and abetted such breaches of fiduciary duties. The complaint seeks to enjoin any transaction, declaratory relief, certain other equitable relief, and unspecified damages and attorneys’ fees and costs. On February 24, 2017, Plaintiff requested voluntary dismissal of the California State Action. On March 7, 2017, the Court dismissed the California State Action without prejudice.

On March 8, 2017, a purported stockholder class action complaint was filed in the United States District Court of the District of Delaware against GigPeak, the members of the board of directors of GigPeak, as well as against IDT and Purchaser, captioned Gusinsky Rev. Trust v. GigPeak Inc. et al., Case No. 1:17-cv-00241-UNA (the “Delaware Action”). On March 13, 2017, a second purported stockholder class action complaint was filed in the United States District Court of the Northern District of California against GigPeak and the members of the board of directors of GigPeak, captioned Mendoza v. GigPeak Inc. et al., Case No. 1:17-cv-01351 (the “California Federal Action”). Both the Delaware Action and California Federal Action complaints allege that the Solicitation/Recommendation Statement on Schedule 14D-9 (the “Solicitation Statement”) filed by GigPeak with the SEC on March 7, 2017 violates Sections 14(e), 14(d) and 20(a) of the Exchange Act. Both complaints allege, inter alia, that the Solicitation Statement omits material information regarding the transactions contemplated by the Merger Agreement, which renders the Solicitation Statement false and misleading. Both complaints seek to enjoin any transaction, declaratory relief, certain other equitable relief, and unspecified damages and attorneys’ fees and costs.

IDT and Purchaser intend to vigorously defend against these Actions.

Section 17 — “Certain Legal Matters; Regulatory Approvals — Antitrust Compliance — HSR Act” of the Offer to Purchase is hereby amended and in its entirety to read as follows:

As of 11:59 p.m., New York City time, on March 13, 2017, the waiting period under the HSR Act applicable to the Offer expired. Accordingly, the condition to the Offer relating to the expiration or termination of the waiting period under the HSR Act has been satisfied.
