CALCULATION OF FILING FEE

Transaction Valuation*	Amount of Filing Fee**
$3,754,827.60	$467.48

The transaction valuation was calculated by multiplying 9,387,069 issued and outstanding shares of common stock, par value $0.005 (the “Shares”), of Cartesian, Inc., a Delaware corporation (“Cartesian”), multiplied by the offer price of $0.40 per Share. The calculation of the filing fee is based on information provided by Cartesian as of April 10, 2018.

** 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 2018, issued August 24, 2017, by multiplying the transaction valuation by 0.0001245.

This Amendment No. 1 (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO filed with the Securities and Exchange Commission (“SEC”) on April 10, 2018 (as amended, the “Schedule TO”) which relates to the tender offer by Cartesian Holdings, Inc., a Delaware corporation (“Merger Sub”) and a wholly owned direct subsidiary of Cartesian Holdings, LLC, a Delaware limited liability company (“Parent”), for all of the outstanding shares of common stock, par value $0.005 per share (“Shares”), of Cartesian, Inc., a Delaware corporation (“Cartesian”), at a price of $0.40 per share, net to the seller in cash, without interest thereon and less any applicable withholding taxes, upon the terms and conditions set forth in the offer to purchase dated April 10, 2018 (the “Offer to Purchase”), a copy of which is attached to the Schedule TO as Exhibit (a)(1)(A), and in the related letter of transmittal (the “Letter of Transmittal”), a copy of which is attached to the Schedule TO as Exhibit (a)(1)(B), which, as each may be amended or supplemented from time to time, collectively constitute the “Offer.” This Amendment also constitutes Amendment No. 1 to the Schedule 13D filed jointly with the SEC by Parent, Merger Sub, Blackstreet Capital Holdings, LLC, BCH Investors, LLC, Blackstreet Capital Investors, LLC and Murry N. Gunty on April 10, 2018 with respect to the Shares.

All the information set forth in the Offer to Purchase, including Schedule I thereto, is incorporated by reference herein in response to Items 1 through 9 and Item 11 of the Schedule TO, and is supplemented by the information specifically provided in the Schedule TO, except that such information is hereby amended and supplemented to the extent provided herein. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Offer to Purchase.

Item 1 through 9 and Item 11.

The Offer to Purchase and Item 1 through 9 and 11 of the Schedule TO, to the extent Item 1 through 9 and 11 incorporate by reference the information contained in the Offer to Purchase, are hereby amended and supplemented by adding the following paragraphs thereto:

“The Offer and withdrawal rights expired as scheduled on May 11, 2018, at one minute after 11:59 p.m., New York City time. The Depositary has advised Parent and Merger Sub that, as of the Expiration Date, an aggregate of 7,200,990 Shares had been tendered and not validly withdrawn pursuant to the Offer, which represented approximately 76.7% of the Shares outstanding as of the Expiration Date (excluding Shares tendered pursuant to guaranteed delivery procedures that have not been delivered in settlement or satisfaction of such guarantee). In addition, as of such time, Notices of Guaranteed Delivery had been delivered for 1,465 Shares, which, when combined with the Shares tendered and not properly withdrawn from the Offer equal approximately 0.02% of the outstanding Shares as of the Expiration Date.

The number of Shares validly tendered and not validly withdrawn in the Offer (excluding Shares tendered pursuant to guaranteed delivery procedures that have not been delivered in settlement or satisfaction of such guarantee) satisfies the Minimum Condition. All conditions to the Offer have been satisfied or waived and Merger Sub has accepted for payment, and expects to promptly pay for, all Shares validly tendered into and not withdrawn from the Offer.

Because less than 90% of the outstanding Shares were purchased in the Offer, Cartesian expects to call the Cartesian Shareholder Meeting to approve the Merger Agreement as soon as practicable. If the holders of more than fifty percent (50%) of the outstanding shares vote to approve the Merger Agreement and the other conditions set forth in the Merger Agreement are satisfied or waived, the Merger will be completed. Pursuant to the Merger Agreement, at the Effective Time, Merger Sub will merge with and into Cartesian, with Cartesian surviving as a wholly owned subsidiary of Parent. In the Merger, each Share issued and outstanding immediately prior to the Effective Time (unless such Share (a) is held by Cartesian immediately prior to the Effective Time or irrevocably accepted by Merger Sub for purchase in the Offer, in which case such Share will be canceled and no payment will be made with respect thereto, or (b) is a Dissenting Share) will be canceled and converted into the right to receive an amount equal to the Offer Price, net to the seller in cash, without interest thereon and subject to any withholding of taxes required by applicable law. As a consequence of the Merger, the Shares will be removed from the OTCQB Marketplace and the Common Stock will be deregistered under the Exchange Act.”
