April 17, 2002
Special Committee to the Board of Directors c/o CombiMatrix Corporation 6500 Harbour Heights Parkway Mukilteo, WA 98275
Gentlemen:
You have requested our opinion as to the fairness, from a financial point of view, to the shareholders ("Minority Shareholders") other than Acacia Research Corporation ("Acacia") of CombiMatrix Corporation ("CombiMatrix" or the "Company") of the consideration ("Consideration") to be received by the Minority Shareholders in the proposed Merger ("Merger") by and among CombiMatrix, Acacia and Combi Acquisition Corp. pursuant to the terms of the Agreement and Plan of Reorganization (the "Agreement") signed on March 20, 2002. The Consideration to be received by the Minority Shareholders in the Merger will consist of one share of Acacia CombiMatrix stock (as defined in the Agreement and the Restated Certificate of Incorporation of Acacia Research Corporation) for each share of CombiMatrix common stock owned by the Minority Shareholders.
A.G. Edwards & Sons, Inc. ("A.G. Edwards"), as part of its investment banking business, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate or other purposes. We are not aware of any present or contemplated relationship among A.G. Edwards, the Company, the Company's directors and officers or its shareholders, or among A.G. Edwards, Acacia (including other related entities), Acacia's directors and officers or shareholders, which in our opinion would affect our ability to render a fair and independent opinion in this matter.
We are acting as exclusive financial advisor to the Special Committee of the Board of Directors of the Company in connection with the Merger and will receive a fee from the Company for our services pursuant to the terms of our engagement letter with the Company dated as of March 13, 2002.
In connection with this opinion, we have reviewed and considered such financial and other matters as we have deemed relevant, including, among other things:
i. the signed Agreement dated March 20, 2002, and discussions with counsel representing Acacia, CombiMatrix and the Special Committee concerning the Agreement and other related documents;
ii. the historical and future business and operations of Acacia, CombiMatrix and Acacia Media Technologies ("Media Technologies");
iii. the historical financial performance of Acacia through a review of their audited financial results;
iv. the historical and forecasted financial statements for CombiMatrix as prepared by CombiMatrix's management;
v. an investigation of the future operational and financial performance and anticipated cash needs of CombiMatrix and Media Technologies, respectively;
vi. an investigation regarding the current operations and future prospects of CombiMatrix and Media Technologies, primarily through discussions with the managements of CombiMatrix and Media Technologies, respectively;
vii. the biological array processor market and the primary market segments CombiMatrix will pursue;
viii. the market data for stocks of public companies in the same or similar markets as CombiMatrix;
ix. an investigation of the existing patent portfolio of Media Technologies through discussions with internal and external counsel representing Media Technologies;
x. an investigation of the role and responsibilities of Acacia concerning the post-merger management and operations of CombiMatrix and Media Technologies;
xi. the history and performance of "tracking" stocks and similar transaction structures;
xii. an investigation of studies related to marketability discounts applied to minority interests in private companies;
xiii. Acacia's annual report on Form 10-K for its fiscal year ended December 31, 2001, Acacia's quarterly reports on Form 10-Q for its fiscal quarters ended March 31, 2001, June 30, 2001 and September 30, 2001, and certain other publicly available information for the Company and Acacia; and
xiv. other analyses which A.G. Edwards deemed necessary.
In preparing our opinion, A.G. Edwards has assumed and relied upon the accuracy and completeness of all financial and other information that was publicly available, or supplied or otherwise made available to us by CombiMatrix, Acacia and Media Technologies. We have not been engaged to, and therefore we have not, verified the accuracy or completeness of any of such information. A.G. Edwards has relied upon the assurances of the managements of CombiMatrix, Acacia and Media Technologies that they are not aware of any facts that would make any financial or other information inaccurate or misleading.
A.G. Edwards has been informed and assumed that financial projections supplied to, discussed with or otherwise made available to us reflect the best currently available estimates and judgments of the management of CombiMatrix as to the expected future financial performance of the Company. A.G. Edwards has not independently verified such information or assumptions nor do we express any opinion with respect thereto.
As discussed with managements of Acacia and Media Technologies, A.G. Edwards relied upon their statements that they had neither prepared nor reviewed any projections or estimates of the potential revenue, income or value that could be derived from any current or future litigation or licensing efforts related to the patents held by Media Technologies and its related entities.
A.G. Edwards has not made any independent valuation or appraisal of the assets or liabilities of CombiMatrix, Acacia or Media Technologies, nor have we been furnished with any such valuations or appraisals. A.G. Edwards also did not independently attempt to assess or value any of the intangible assets (including goodwill) nor did it make any independent assumptions with respect to their application in the Merger.
A.G. Edwards' opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. The analyses performed by A.G. Edwards are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by such analyses. It should be understood that, although subsequent developments may affect our opinion, A.G. Edwards does not have any obligation to update, revise or reaffirm our opinion and it expressly disclaims any responsibility to do so. Our opinion as expressed herein, in any event, is limited to the fairness, from a financial point of view, to the Minority Shareholders, of the Consideration to be received in the Merger pursuant to the Agreement.
For purposes of rendering our opinion we have assumed in all respects material to our analysis that the representations and warranties of each party contained in the Agreement are true and correct, that each party will perform all of the covenants and agreements required to be performed by it under the Agreement and that all conditions to the consummation of the Merger will be satisfied without waiver thereof. We have also assumed that all governmental, regulatory and other consents and approvals contemplated by the Agreement will be obtained and that in the course of obtaining any of those consents, no restrictions will be imposed or waivers made that would have an adverse effect on the contemplated benefits of the Merger.
A.G. Edwards was not engaged to and did not review, nor is it expressing any opinion with respect to, any alternative transaction or strategic alternatives that may be available to the Company or the Minority Shareholders. We are not expressing any opinion as to what the value of the Company's common stock has been or will be, nor have we considered the tax implications of the Merger. Our opinion also does not address the merits of the underlying decision by the Company to engage in the Merger.
In rendering its opinion, A.G. Edwards assumed that (a) the Merger will be accounted for in accordance with U.S. Generally Accepted Accounting Principles and (b) the Merger will be consummated on the terms contained in the Agreement without any waiver of any material terms or conditions by CombiMarix.
G-3
It is understood that this letter is for the information of the Special Committee of the Board of Directors and does not constitute a recommendation as to how any holder of the outstanding shares of the Company's common stock should vote with respect to the Merger. This opinion may not be reproduced, summarized, excerpted from or otherwise publicly referred to without our prior written consent.
Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration to be received by the Minority Shareholders in the Merger pursuant to the Agreement is fair, from a financial point of view, to the Minority Shareholders.
Very truly yours,
A.G. EDWARDS & SONS, INC.
