Dear Sirs:

1. Introductory. ANADIGICS, Inc., a Delaware corporation (“Company”), proposes to issue and sell 9,200,000 shares (“Firm Securities”) of its common stock, par value $0.01 per share (“Securities”), and also proposes to issue and sell to the Underwriters, at the option of the Underwriters, an aggregate of not more than 1,350,000 additional shares (“Optional Securities”) of its Securities as set forth below. The Firm Securities and the Optional Securities are herein collectively called the “Offered Securities”. The Company hereby agrees with the several Underwriters named in Schedule A hereto (“Underwriters”) as follows:

2. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the several Underwriters that:

(a) A registration statement (No. 333-110538), including a prospectus, relating to the Registered Securities has been filed with the Securities and Exchange Commission (“Commission”) and has become effective; no stop order suspending the effectiveness of such registration statement is in effect, and no proceedings for such purpose are pending before or, to the Company’s knowledge, threatened by the Commission. Such registration statement, as amended, as of any time, means the “Registration Statement” in the form then filed with the Commission, including any document incorporated by reference therein and any prospectus or prospectus supplement deemed or retroactively deemed to be a part thereof that has not been superseded or modified. “Registration Statement” without reference to a time means the Registration Statement as of the time of the first contract of sale for the Offered Securities, which time shall be considered the “effective date” of the Registration Statement. For purposes of this definition, information contained in a form of prospectus or prospectus supplement that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Registration Statement as of the time specified in Rule 430B. “Statutory Prospectus” as of any time means the prospectus relating to the Offered Securities that is included in the Registration Statement immediately prior to that time, including any document incorporated by reference therein and any basic prospectus or prospectus supplement deemed to be a part thereof that has not been superseded or modified. For purposes of this definition, information contained in a form of prospectus (including a prospectus supplement) that is deemed

retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Statutory Prospectus only as of the actual time that form of prospectus (including a prospectus supplement) is filed with the Commission pursuant to Rule 424(b). “Prospectus” means the Statutory Prospectus that discloses the public offering price and other final terms of the Offered Securities and otherwise satisfies Section 10(a) of the Securities Act of 1933, as amended (the “Act”) including any document incorporated by reference therein and any basic prospectus or prospectus supplement deemed to be a part thereof that has not been superseded or modified. “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433, relating to the Offered Securities in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g). “General Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule B to this Agreement. “Limited Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not a General Use Issuer Free Writing Prospectus, as evidenced by its being specified in Schedule B to this Agreement. “Applicable Time” means 6:00 p.m. (Eastern time) on the date of this Agreement.

(b) (i) On the effective date of the registration statement relating to the Offered Securities, such registration statement conformed in all respects to the requirements of the Act and the rules and regulations of the Commission (“Rules and Regulations”) and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) on the date of this Agreement, the Registration Statement conforms, and at the time of filing of the Prospectus pursuant to Rule 424(b) the Registration Statement and the Prospectus will conform, in all respects to the requirements of the Act and the Rules and Regulations, and neither of such documents includes, or will include, any untrue statement of a material fact or omits, or will omit, to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from a Registration Statement or the Prospectus based upon written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information is that described as such in Section 8(b) hereof.

(c) As of the Applicable Time, neither (i) the General Use Issuer Free Writing Prospectus(es) issued at or prior to the Applicable Time, the Statutory Prospectus and the price to the public of the Offered Securities, the underwriting discount relating to the Offered Securities and the number of Offered Securities being offered in the offering, each as set forth in Schedule C, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Limited Use Issuer Free Writing Prospectus, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from any prospectus included in the Registration Statement or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8(b) hereof.

If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict

with the information then contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, (i) the Company has promptly notified or will promptly notify the Representative and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8(b) hereof.

(a)The Company represents and agrees that, unless it obtains the prior consent of the Lead Underwriter, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Lead Underwriter, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Lead Underwriter is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

7. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Firm Securities on the First Closing Date and the Optional Securities to be purchased on each Optional Closing Date will be subject to the accuracy of the representations and warranties on the part of the Company herein, to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

(a) The Representative shall have received letters, dated the date of this Agreement, of X.X. Xxxx LLP and Ernst & Young LLP in form and substance satisfactory to the Lead Underwriter containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement, the General Disclosure Package and the Prospectus.

(b) The Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 5(b) of this Agreement. No stop order suspending the effectiveness of the Registration Statement or of any part thereof shall have been issued and no proceedings for that purpose shall have been instituted or, to the best of the Company’s knowledge or any Underwriter, shall be contemplated by the Commission.

(c) Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as one enterprise which, in the judgment of a majority in interest of the Underwriters including the Representative, is material and adverse and makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Offered Securities; (ii) any downgrading in the rating of any debt securities of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement that the Company has been placed on negative outlook; (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of a majority in interest of the Underwriters including the Representative, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any material suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum prices for trading on such exchange; (v) or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (vi) any banking moratorium declared by U.S. Federal or New York authorities; (vi) any major disruption of settlements of securities or clearance services in the United States or (viii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of a majority in interest of the Underwriters including the Representative, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Offered Securities.

(d) The Representative shall have received an opinion, dated such Closing Date, of Xxxxxx Xxxxxx & Xxxxxxx LLP, counsel for the Company, in form and substance satisfactory to counsel for the Underwriters to the effect set forth in Exhibit A-1.

(e) The Representative shall have received an opinion, dated such Closing Date, of Xxxxxx Xxxxx & Bockius, special counsel for the Company, in form and substance satisfactory to the counsel for the Underwriters, to the effect set forth in Exhibit A-2.

(f) The Representative shall have received from Xxxxx Xxxx & Xxxxxxxx, counsel for the Underwriters, such opinion or opinions, dated such Closing Date, with respect to the incorporation of the Company, the validity of the Offered Securities delivered on such Closing Date, the Registration Statements, the Prospectus, the General Disclosure Package and other related matters as the Representative may require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(g) The Representative shall have received a certificate, dated such Closing Date, of the President or any Vice President and a principal financial or accounting officer of the Company in which such officers, to the best of their knowledge after reasonable investigation, shall state that: the representations and warranties of the Company in this Agreement are true and correct as of the Closing Date; the Company has complied with all agreements and satisfied all conditions

(h) The Representative shall have received a letter, dated such Closing Date, of X.X. Xxxx LLP which meets the requirements of subsection (a) of this Section, except that the “cut-off date” referred to in such letter shall be a date not more than three days prior to such Closing Date for the purposes of this subsection. (i) On or prior to the date of this Agreement, the Representative shall have received lockup letters from each of the executive officers and directors of the Company in the form set forth in Schedule D to this Agreement.

The Company will furnish the Representative with such conformed copies of such opinions, certificates, letters and documents as the Representative reasonably requests. The Lead Underwriter may in its sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder, whether in respect of an Optional Closing Date or otherwise.

	8. Indemnification and Contribution.

	(a) The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, each Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below. (b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, its directors and officers and each person, if any who controls the Company within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, each Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the

extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the fourth paragraph under the caption “Underwriting” and the information appearing under the caption “Underwriting” relating to stabilization transactions, over-allotment transactions, syndicate covering transactions, penalty bids and passive market making.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue

statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed (or authorized an attorney-in-fact to sign on such officer’s behalf) a Registration Statement and to each person, if any, who controls the Company within the meaning of the Act.

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Lead Underwriter may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Lead Underwriter and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company and the Underwriters pursuant to Section 8 shall remain in effect, and if any Offered Securities have been purchased hereunder the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than

solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 7(c), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

11. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to the Representative at Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: Transactions Advisory Group, or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at ANADIGICS, Inc., 000 Xxxxx Xxxxxx Xxxx, Xxxxxx, XX 00000, Attention: Xxxxxx X.

Xxxxxx, Esq.; provided , however , that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Underwriter.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder.

13. Representation of Underwriters. The Representative will act for the several Underwriters in connection with this financing, and any action under this Agreement taken by the Representative will be binding upon all the Underwriters.

14. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

15. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) The Representative has been retained solely to act as underwriter in connection with the sale of the Company’s securities and that no fiduciary, advisory or agency relationship between the Company and the Representative has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Representative has advised or is advising Company on other matters;

(b) the price of the securities set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Representative and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) it has been advised that the Representative and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Representative has no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) it waives, to the fullest extent permitted by law, any claims it may have against the Representative for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Representative shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

16. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to principles of conflicts of laws.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

If the foregoing is in accordance with the Representative’s understanding of our agreement, kindly sign and return to the Company one of the counterparts hereof, whereupon it will become a binding agreement between the Company and the several Underwriters in accordance with its terms.

Re: ANADIGICS, Inc.

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 7(d) of the Underwriting Agreement dated March [ ], 2006 (the “Underwriting Agreement”), between ANADIGICS, Inc., a Delaware corporation (the “Company”) and Credit Suisse Securities (USA) LLC, as representative of the several underwriters (the “Underwriters”) named in Schedule I thereto. The Underwriting Agreement relates to the issuance and sale by the Company to the Underwriters of [ ] shares of common stock, par value $.01 per share (the “Common Stock”) of the Company comprised of [ ] shares of Common Stock offered by the Company in the primary offering and [ ] shares of Common Stock offered by the Company pursuant to the exercise of an over-allotment option by the Underwriters. For purposes of this opinion letter, (a) capitalized terms used in this opinion letter have the respective meanings set forth in the Underwriting Agreement unless otherwise defined herein and (b) the term “Material Agreements” shall mean the agreements listed on Exhibit A annexed to this letter. The Company has advised us that the Material Agreements are the only outstanding agreements of the Company and its subsidiaries which are material to the Company and its subsidiaries taken as a whole.

We have examined the originals, photocopies or conformed copies of all such records of the Company and its subsidiaries and all such agreements, certificates of public officials, certificates of officers and representatives of the Company and such other documents as we have deemed relevant and necessary as a basis for the opinions hereinafter expressed. In such examinations, we have assumed the genuineness of all signatures on original documents and the conformity to the originals of all copies submitted to us as conformed copies or photocopies. We have relied, to the extent we deem such reliance proper, on certificates of officers of the Company and other documents as to factual matters.
Based on the foregoing and subject to the qualifications expressed herein, we are of the opinion that:

1. The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, with power and authority (corporate and other) to own its properties, conduct its business, to execute and deliver the Underwriting Agreement and to authorize, issue and sell the Offered Securities as described in the General Disclosure Package and Prospectus.

2. The Company has an authorized capitalization as set forth in the General Disclosure Package and Prospectus, and all of the issued shares of capital stock of the Company (including the Offered Securities) have been duly and validly authorized and issued and are fully paid and non-assessable and conform to the description thereof contained in the General Disclosure Package in all material respects; and the stockholders of the Company have no preemptive rights with respect to the Securities.

3. The Company has been duly qualified as a foreign corporation for the transaction of business and is in good standing under the laws of each other jurisdiction in which it owns or leases properties or conducts any business, so as to require such qualification, or is not subject to any material liability or disability by reason of the failure to be so qualified in any such jurisdiction.

4. To the best of our knowledge and other than as set forth in the General Disclosure Package and Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject which, if determined adversely to the Company or any of its subsidiaries, would individually or in the aggregate have a Material Adverse Effect; and, to the best of our knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

5. To the best of our knowledge, there are no contracts, agreements or understandings between the Company and any person granting such person the right to require the Company to file a registration statement under the Act with respect to any securities of the Company owned or to be owned by such person or to require the Company to include such securities in the securities registered pursuant to the Registration Statement or any securities being registered pursuant to any other registration statement filed by the Company under the Act, except for (i) the Registration Rights Agreement, dated as of November 21, 2001, between the Company and Xxxxxxx, Xxxxx & Co., (ii) the Registration Rights Agreement, dated as of September 24, 2004, between the Company and Xxxxxx Xxxxxxx & Co. Incorporated and (iii) the Registration Rights Agreement, dated as of March 31, 2003, between the Company and R.F. Solutions, Inc.

6. The Underwriting Agreement has been duly authorized, executed and delivered by the Company

7. No consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body having jurisdiction over the Company or any of its subsidiaries or their properties is required for the issuance and sale of the Offered Securities or the consummation by the Company of the transactions contemplated by the Underwriting Agreement, except consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws or such approvals as have been obtained from the Securities and Exchange Commission (the “Commission”).

8. The Company is not (A) in violation of its Amended and Restated Certificate of Incorporation or by-laws or (B) to the best of our knowledge, after due inquiry, in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any Material Agreement.

9. The Company is not, and after giving effect to the offering and sale of the Offered Securities and the application of the proceeds thereof as described in the Prospectus, will not be, required to register as an “investment company” as such term is defined in the Investment Company Act of 1940.

10. The statements set forth in the General Disclosure Package and the Prospectus under the caption “Description of Capital Stock” insofar as they purport to constitute a summary of the terms of the Securities are accurate, complete and fair in all material respects.

11. The execution, and delivery of the Underwriting Agreement and the performance by the Company of its obligations under the Underwriting Agreement did not and do not conflict with or constitute a breach or violation of or default under (a) any Material Agreement, (b) its Amended and Re-stated Certificate of Incorporation or By-laws, or (c) any applicable law, rule or administrative regulation or order known to us of any governmental agency or body or any court having jurisdiction over the Company or any subsidiary of the Company or any of their respective properties, except in the case of clauses (a) and (c), respectively, for conflicts, breaches, violations or defaults that individually or in the aggregate would not have a Material Adverse Effect.

12.

All capitalized terms used herein and not defined herein shall have the meanings ascribed to such terms in the Underwriting Agreement.

We have participated in conferences with officers and other representatives of the Company, representatives of the independent registered public accounting firm for the Company, representatives of counsel for the Underwriters and representatives of the Underwriters at which the contents of the Registration Statement, the Prospectus and the documents specified in Schedule A hereto (the “General Disclosure Documents”) and related matters were discussed. Although we have made certain inquiries and investigations in connection with the preparation of the Registration Statement, the Prospectus and the General Disclosure Documents, the limitations inherent in the role of outside counsel are such that we cannot and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in such documents, except as provided in paragraph 10 of our opinion to you of even date herewith. Subject to the foregoing, we advise you that no facts have come to our attention that lead us to believe that (i) the Registration Statement, including the documents incorporated therein by reference, at the time the Registration Statement became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Prospectus, as of its date or as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the General Disclosure Documents, taken together, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no comment with respect to the financial statements or other financial data that is included in or omitted from the Registration Statement, the Prospectus or the General Disclosure Documents).

This letter is solely for your benefit in connection with the issuance of the Securities on the date hereof and may not be delivered to, or used for any other purpose or relied upon by any person other than you, without our prior written consent.

Very truly yours,

Based upon our knowledge of the Company’s intellectual property matters as set forth above, inquiries of officials of the Company regarding factual matters and our general knowledge of applicable law, it is our opinion and judgment that:

A. The Company has good title to and ownership of all the patents owned by it of record, free and clear of all liens and other encumbrances, except such as do not materially affect the value of such patents and do not interfere with the use made or proposed to be made of such patents by the Company and its subsidiaries.

B. To our knowledge, there are no legal or governmental proceedings that involve a challenge to the rights of the Company or its subsidiaries in, or a challenge to the scope, validity or enforceability of, any patents, trademarks, copyrights, trade secrets or other intellectual property rights (“Intellectual Property”) of the Company and its subsidiaries, and to our knowledge, no such proceedings are threatened or contemplated.

C.

D. The Company has taken reasonable measures to prevent the unauthorized dissemination and publication of the confidential information of the Company, its subsidiaries and third parties in the possession of the Company or its subsidiaries.

We express no opinion other than as stated above, and neither that opinion nor any other statements above are intended to imply or be an opinion on the adequacy of the disclosure concerning such matters under the Federal securities laws.

The information contained in this opinion is applicable as of March ___, 2006, and is based on facts and circumstances presently known to us. We assume no continuing obligation to advise Credit Suisse, or to

advise anyone else, of any change after that date or of any facts and circumstances not presently known to us.
