CALCULATION OF FILING FEE


Transaction Valuation(1)		Amount of Filing Fee(2)
$113,530,747		$13,011

(1)

Calculated solely for purposes of determining the filing fee. The calculation assumes the purchase of 7,462,688 shares of common stock, par value $0.001 per share, at $13.60 per share (which number includes 1,650,850 shares of common stock issuable pursuant to the conversion of preferred stock, par value $0.001 per share). The transaction value also includes the aggregate offer price for 1,489,875 shares issuable pursuant to outstanding options with an exercise price less than $13.60 per share, which is calculated by multiplying the number of shares underlying such outstanding options by an amount equal to $13.60 minus the weighted average exercise price of such options.

This Amendment No. 2 (this “Amendment”) to the Tender Offer Statement on Schedule TO (as amended or supplemented, the “Schedule TO”) amends and supplements the Schedule TO relating to the tender offer by Backbone Acquisition Sub, Inc., a Delaware corporation (“Purchaser”) and a wholly-owned subsidiary of Solutia Inc., a Delaware corporation (“Parent”), for all of the outstanding common stock, par value $0.001 per share (the “Shares”), of Southwall Technologies Inc., a Delaware corporation (the “Company”), at a price of $13.60 per Share, net to the seller thereof 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 October 25, 2011 (the “Offer to Purchase”), a copy of which is attached as Exhibit (a)(1)(A), and in the related letter of transmittal (the “Letter of Transmittal”), a copy of which is attached as Exhibit (a)(1)(B), which, together with any amendments or supplements thereto, collectively constitute the “Offer.” Except as specifically provided herein, this Amendment does not modify any of the information previously reported on the Schedule TO.

All the information set forth in the Offer to Purchase, including all schedules and annexes thereto, is incorporated herein by reference in response to Items 1 through 9 and Item 11 in this Schedule TO, and is supplemented by the information specifically provided in this Schedule TO.

Item 1 through 9 and Item 11 of the Schedule TO, which incorporate by reference the information contained in the Offer to Purchase, are hereby amended as follows:

(1) In Section 7 of the Offer to Purchase entitled “Certain Information Concerning the Company,” the second paragraph on page 22 is hereby deleted in its entirety and replaced with the following:

“Although neither Parent nor Purchaser has any knowledge that such information is untrue, neither Parent nor Purchaser has independently verified the accuracy or completeness of the information contained in this Offer to Purchase with respect to the Company or any of its subsidiaries or affiliates or any failure by the Company to disclose any events which may have occurred or may affect the significance of any such information but which are unknown to Parent or Purchaser.”

(2) In Section 8 of the Offer to Purchase entitled “Certain Information Concerning Parent and Purchaser,” the last paragraph on page 24 is hereby deleted in its entirety and replaced with the following:

(3) In Section 11 of the Offer to Purchase entitled “The Merger Agreement,” the first paragraph of the sub-section captioned “Representations and Warranties” on page 37 is hereby deleted in its entirety and replaced with the following:

“The Merger Agreement contains representations and warranties made as of specific dates by the Company to Parent and Purchaser and by Parent and Purchaser to the Company. These representations and warranties were made to allocate contractual risk between the parties to the Merger Agreement and not to establish such matters as facts. Moreover, the representations and warranties contained in the Merger Agreement have been negotiated with the principal purpose of establishing the circumstances in which a party may have the right not to close the Offer or the Merger if certain representations and warranties prove to be untrue due to a change in circumstance or otherwise. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and may be subject to important qualifications and limitations agreed to by the parties thereto.”

(4) In Section 11 of the Offer to Purchase entitled “The Merger Agreement,” sub-section (i)(a) of the third bullet point contained in the second paragraph of the sub-section captioned “Effect of Termination” on page 48 is hereby deleted in its entirety and replaced with the following:

“by either Parent or the Company due to the Offer not having been consummated by the End Date (taking into account the automatic extension thereof discussed above) or due to the Offer having expired or been terminated without Purchaser having accepted for payment any Shares pursuant to the Offer and at the time of such expiration or termination the only condition that has not been satisfied is the Minimum Condition or”

(5) In Section 15 of the Offer to Purchase entitled “Conditions of the Offer,” the first full bullet point on page 55 is hereby deleted in its entirety and replaced with the following:

•

Item 11. Additional Information.

Regulation M-A Item 1011

(a) Agreements, Regulatory Requirements and Legal Proceedings. Item 11(a) of the Schedule TO is hereby amended and supplemented as follows:

(2) Section 16 of the Offer to Purchase entitled “Certain Legal Matters; Regulatory Approvals” is hereby amended and supplemented by adding the following paragraphs immediately after the last paragraph of the sub-section captioned “General” and immediately prior to the sub-section captioned “State Takeover Statutes” on page 55:

Litigation. On October 31, 2011 and November 1, 2011, three purported class action lawsuits were filed on behalf of the Company’s stockholders related to the sale of the Company to Parent and Purchaser. The suits name as defendants some combination of the Company and members of the Company Board (collectively, the “Company Defendants”), Parent and Purchaser (collectively, the “Parent Defendants”), Dolphin and certain stockholders affiliated with the Needham Funds (collectively, the “Stockholder Defendants”).

Two complaints were filed in the Santa Clara Superior Court of California on October 31, 2011: Geometric Trading Company v. Capovilla et al. (Case No. 111CV212244); and Beckett v. Capovilla et al. (Case No. 111CV212260). One complaint was filed in the Court of Chancery in the State of Delaware on November 1, 2011: Parcell v. Southwall Technologies, Inc. et al. (C.A. No. 7003-VCL).

The complaints generally allege that (i) the Company Defendants breached their fiduciary duties of care, loyalty and good faith by facilitating the sale of the Company to Parent and Purchaser through an unfair process at an unfair price; (ii) the Company Defendants breached their fiduciary duty of disclosure by omitting or

misstating material information regarding the sale; (iii) the Offer and the Merger unfairly benefit certain members of the Company Board, to the disadvantage of Company stockholders; (iv) the Stockholder Defendants breached their fiduciary duties to minority stockholders by facilitating the sale of the Company to Parent and Purchaser; and (v) the Stockholder Defendants and Parent Defendants aided and abetted the Company Defendants’ alleged breaches of fiduciary duties.

The complaints seek, among other relief, to enjoin the Offer and the Merger, a declaration that the Company Defendants have breached their fiduciary duties to stockholders or aided and abetted those breaches, compensatory damages, or rescission of the Offer and the Merger in the event such transactions have been completed and an award of costs, including reasonable attorneys’ and expert fees.

On November 1, 2011, plaintiff Parcell filed a motion to expedite the proceedings in Delaware, seeking to expedite discovery and schedule a preliminary injunction hearing. The Delaware Court of Chancery denied the motion on November 8, 2011.

On November 3, 2011, plaintiff Geometric Trading Company filed an application for a temporary restraining order and expedited discovery in the Santa Clara Superior Court of California. A hearing on the application has been set for November 21, 2011.
