To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

We have been engaged by Tiger Merger Sub, Inc., a Delaware corporation (the “Offeror”) and a wholly owned subsidiary of Autokiniton US Holdings, Inc., a Delaware corporation (“Parent”), which is controlled by certain private equity funds for which KPS Investors IV, Ltd., a Cayman Islands exempted company (“KPS IV”), acts as General Partner, to act as information agent (“Information Agent”) in connection with the Offeror’s offer to purchase all of the issued and outstanding shares (the “Shares”) of common stock, par value $0.01 per share, of Tower International, Inc., a Delaware corporation (“Tower”), at a purchase price of $31.00 per Share, net of applicable withholding and without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated August 15, 2019 (the “Offer to Purchase”), and in the related Letter of Transmittal (the “Letter of Transmittal” which, together with the Offer to Purchase, as each may be amended or supplemented from time to time as permitted under the Merger Agreement described below, collectively constitute the “Offer”). Please furnish copies of the enclosed materials to those of your clients for whom you hold Shares registered in your name or in the name of your nominee.

For your information and for forwarding to your clients for whom you hold Shares registered in your name or in the name of your nominee, we are enclosing the following documents:

2. the Letter of Transmittal to be used by stockholders of Tower in accepting the Offer and tendering Shares, including IRS Form W-9;

3. the Notice of Guaranteed Delivery to be used to accept the Offer if Shares to be tendered and/or all other required documents cannot be delivered to Broadridge Corporate Issuer Solutions, Inc. (the “Depositary and Paying Agent”) by the expiration of the Offer or if the procedure for book-entry transfer cannot be completed by the expiration of the Offer;

4. Tower’s Solicitation/Recommendation Statement on Schedule 14D-9;

5. the form of letter that may be sent to your clients for whose accounts you hold Shares in your name or in the name of your nominee, with space provided for obtaining such clients’ instructions with regard to the Offer; and

Certain conditions to the Offer are described in Section 13—“Conditions of the Offer” of the Offer to Purchase. There is no financing condition to the Offer.

Your prompt action is requested. We urge you to contact your clients as promptly as possible. Please note that the Offer will expire at 5:00 P.M., New York City time, on September 13, 2019, unless the Offer is extended or earlier terminated. Previously tendered Shares may be withdrawn at any time until the Offer has expired.

The Offer is being made in connection with the Agreement and Plan of Merger, dated as of July 12, 2019, by and among Tower, Parent and the Offeror (as it may be amended from time to time, the “Merger Agreement”). The Merger Agreement provides, among other things, that as soon as practicable following the consummation of the Offer and subject to certain conditions, the Offeror will merge with and into Tower (the “Merger”), without the vote of stockholders of Tower, pursuant to Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”) with Tower surviving as a wholly-owned subsidiary of Parent. As a result of the Merger, the Shares will cease to be publicly traded.

The Board of Directors of Tower unanimously (a) determined that it is advisable and in the best interests of Tower and its stockholders to enter into the Merger Agreement and to consummate the transactions contemplated by the Merger Agreement, including, without limitation, the Offer and the Merger, (b) determined that the Merger Agreement and the transactions contemplated by the Merger Agreement, including, without limitation, the Offer and the Merger, are fair to and in the best interests of Tower and its stockholders, (c) approved and declared advisable the Merger Agreement, the Merger, the Offer and the other transactions contemplated by the Merger Agreement, in each case, in accordance with the DGCL, (d) resolved that the Merger Agreement and the Merger shall be governed by and effected under Section 251(h) of the DGCL and (e) recommended that the stockholders of Tower accept the Offer and tender their Shares in and pursuant to the Offer.

For Shares to be validly tendered pursuant to the Offer, (a) the share certificates or confirmation of receipt of such Shares under the procedure for book-entry transfer, together with a properly completed and duly executed Letter of Transmittal, including any required medallion signature guarantees, or an “Agent’s Message” (as defined in Section 3—“Procedures for Tendering Shares” of the Offer to Purchase) in the case of book-entry transfer, and any other documents required in the Letter of Transmittal, must be timely received by the Depositary and Paying Agent or (b) the tendering stockholder must comply with the guaranteed delivery procedures, all in accordance with the Offer to Purchase and the Letter of Transmittal.

Neither Parent nor the Offeror will pay any fees or commissions to any broker or dealer or other person (other than the Information Agent and the Depositary and Paying Agent, as described in the Offer to Purchase) for soliciting tenders of Shares pursuant to the Offer. The Offeror will, however, upon request, reimburse brokers, dealers, commercial banks, trust companies and other nominees for reasonable and necessary costs and expenses incurred by them in forwarding materials to their customers. The Offeror will pay all stock transfer taxes applicable to its purchase of Shares pursuant to the Offer, subject to Instruction 6 of the Letter of Transmittal.

The Offer is not being made to, nor will tenders be accepted from or on behalf of, holders of Shares in any jurisdiction in which the making of the Offer or acceptance thereof would not be in compliance with the securities, “blue sky” or other laws of such jurisdiction.

Questions and requests for assistance or for additional copies of the enclosed materials may be directed to the Information Agent, at the address and telephone number set forth in the Offer to Purchase. Additional copies of the enclosed materials will be furnished at the Offeror’s expense.

Very truly yours,
