CALCULATION OF FILING FEE

Transaction Valuation (1)	Amount of Filing Fee (2)
$32,261,090.75	$3,248.70

(1) Estimated solely for purposes of calculating the amount of the filing fee. The transaction valuation was calculated by adding the sum of (A) 88,836,561 outstanding shares of common stock, par value $0.01 per share (“Shares”), of ANADIGICS, Inc. (“Anadigics”), (B) 8,542 Shares subject to issuance pursuant to outstanding options with an exercise price less than the offer price of $0.35 per Share, (C) 3,044,442 Shares subject to issuance pursuant to outstanding time-based restricted stock units, and performance-based restricted stock units earned prior to the end of the offer, and (D) up to 285,000 Shares issuable with respect to the current offering period under Andigics’s Employee Stock Purchase Plan, with such sum multiplied by the offer price of $0.35 per Share. The calculation of the filing fee is based on information provided by Anadigics as of November 20, 2015.

(2) The filing fee was calculated in accordance with Rule 0-11 of the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory #1 for fiscal year 2016, issued August 27, 2015, by multiplying the transaction value by .0001007.

This Amendment No. 4 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO filed by GaAs Labs, LLC, a California limited liability company (“GaAs Labs”), Aloha Holding Company, Inc., a Delaware corporation (“Aloha”) and wholly-owned subsidiary of GaAs Labs, and Aloha Acquisition Sub, Inc., a Delaware corporation (“Purchaser”) and a wholly-owned subsidiary of Aloha, with the Securities and Exchange Commission on November 24, 2015 (together with any amendments and supplements thereto, the “Schedule TO”). This Schedule TO relates to the offer by Purchaser to purchase all of the outstanding shares of common stock, par value $0.01 per share (the “Shares”), of ANADIGICS, Inc., a Delaware corporation (“Anadigics”), at a price of $0.35 per Share, net to the seller in cash, without interest, less any applicable withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated November 24, 2015 (as it may be amended or supplemented, the “Offer to Purchase”), and the related Letter of Transmittal (as it may be amended or supplemented, the “Letter of Transmittal,” and together with the Offer to Purchase, the “Offer”), copies of which are attached to this Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively. Capitalized terms used but not otherwise defined herein shall have the meaning ascribed to such terms in the Offer to Purchase.

All information contained in the Offer to Purchase and the accompanying Letter of Transmittal, including all schedules thereto, is hereby incorporated by reference in response to Items 1 through 9 and Item 11 in the Schedule TO.

This Amendment is being filed to amend and supplement Items 1 through 9 and Item 11 as provided below

Items 1 through 9 and Item 11.

Items 1 through 9 and Item 11 of the Schedule TO are hereby amended and supplemented as follows:

On December 24, 2015, pursuant to the Merger Agreement, Aloha and Purchaser extended the expiration date of the Offer. The Offer was previously scheduled to expire at 11:59 P.M. (New York City time) on December 23, 2015. The Expiration Date of the Offer is extended to 11:59 P.M. (New York City time) on January 8, 2016, unless further extended. The Depositary has advised Purchaser that, as of 5:00 p.m., New York City time, on December 23, 2015, 3,218,686 shares of common stock of Anadigics were tendered pursuant to the tender offer, which represented approximately 3.6% of the outstanding shares of common stock of Anadigics.

On December 24, 2015, GaAs Labs issued a press release announcing the extension of the Offer. The full text of the press release is attached as Exhibit (a)(5)(A) to the Schedule TO and is incorporated herein by reference.

All references in the Offer to Purchase (Exhibit (a)(1)(A)), Letter of Transmittal (Exhibit (a)(1)(B)), Notice of Guaranteed Delivery (Exhibit (a)(1)(C)), Letter to Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees (Exhibit (a)(1)(D)) and Letter to Clients for Use by Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees (Exhibit (a)(1)(E)) of the expiration date of the Offer being “11:59 P.M., New York City time, on December 23, 2015” are amended and replaced with “11:59 P.M., New York City time, on January 8, 2016.”

The information set forth in Section 11 of the Offer to Purchase entitled “Background of the Offer; Past Contacts, Transactions, Negotiations and Agreements with Anadigics” is amended and supplemented by adding the following paragraphs at the end of the section:

“On November 24, 2015, the Offer commenced and the Schedule TO was filed with the SEC. Also on November 24, 2015, Anadigics filed its Solicitation/Recommendation Statement on Schedule 14D-9.

On December 7, 2015, Anadigics announced that the Go-Shop Period elicited Acquisition Proposals, which the Anadigics Board determined are likely to lead to a Superior Offer, as defined in the Merger Agreement. Therefore, Anadigics deemed certain bidders as Excluded Parties, as defined in the Merger Agreement, and Anadigics informed Aloha and Purchaser that it intended to continue negotiations with each of these Excluded Parties.

On December 15, 2015, Aloha and Purchaser received written notice of a Superior Offer from Anadigics which stated that Anadigics had received a definitive proposal from another party (the “Competing Bidder”) to acquire all outstanding Shares for $0.48 per share in cash (the “New Proposal”).

On December 16, 2015, Mr. Ocampo contacted Mr. Michels to express that Purchaser would be willing to increase its purchase price to match that of the New Proposal. In addition, representatives of Aloha and Purchaser discussed with Needham the proposed purchase price increase, an increase of the termination fee and other logistics. Conversations between the Purchaser and Anadigics continued through December 22, 2015.

On December 21, 2015, representatives of Aloha and Purchaser delivered an executed amendment to the Merger Agreement to Needham with an offer price of $0.48 per Share, a termination fee of $2.5 million and certain other amendments.

On December 23, 2015, Anadigics gave written notice to Aloha and Purchaser that it received a proposed amendment to the Competing Bidder’s proposal that increases the proposed offer price to $0.54 per Share, and that the Anadigics Board determined that the amended proposal constitutes a Superior Offer. Pursuant to the Merger Agreement, Aloha and Purchaser have two business days to negotiate a proposal with Anadigics that would cause the amended Acquisition Proposal to no longer constitute a Superior Offer.

On December 24, 2015, GaAs Labs issued a press release announcing the extension of the Offer through 11:59 P.M., New York City time, on January 8, 2016.”

The seventh paragraph in Section 2 of the Offer to Purchase entitled “Acceptance for Payment and Payment for Shares” is amended by deleting the phrase “or unless otherwise mutually agreed by us and Anadigics” from the end of the paragraph.

Section 7 of the Offer to Purchase entitled “Certain Information Concerning Anadigics” is amended by deleting the first paragraph in its entirety.

Items 12. Exhibits.

Item 12 of the Schedule TO is hereby amended and supplemented by adding the following exhibits:
