ORCA Series 5 products and Series 5 related FPSC Products. Seller agrees to use its reasonable commercial efforts to exercise whatever rights may be available to Seller to provide Buyer access to the TSMC model files for the ORCA Series 5 products and Series 5 related FPSC Products; provided, however, that any such access shall be for use only in connection with the manufacturing of wafers performed by TSMC for Buyer. Seller shall also provide notice to TSMC that TSMC may provide Buyer with access to, and use for the benefit of Buyer, any Technical Information of Seller relating to ORCA Series 5 products and Series 5 related FPSC Products disclosed or provided by Seller to TSMC for use only in connection with the manufacturing of wafers performed by TSMC for Buyer. Seller further agrees to use its reasonable commercial efforts to assist Buyer in obtaining access and rights to such Technical Information provided by Seller to TSMC so as to permit Buyer to design ORCA Series 5 products and Series 5 related FPSC Products for manufacture by TSMC.

5.8 Use of Agere Systems' or Lucent Technologies' Name

(a) Buyer agrees that as soon as reasonably practicable after the Closing but not in any event later than twelve months (12) following the Closing, it shall ▇▇▇▇ product, both internally and externally, with Buyer's name and ▇▇▇▇ and shall cease to ▇▇▇▇ product with the names, marks or other indicia of "Agere," "Agere Systems," "Lucent," "Lucent Technologies" or other similar ▇▇▇▇ (the "Agere Marks") and that if it uses such Agere Marks on a product it shall also ▇▇▇▇ such product externally with Buyer's name and/or ▇▇▇▇. In addition following the Closing, Buyer may continue to use or dispose of any existing stock of Inventory or packaging or shipping materials on hand that bear the Agere Marks, in a manner consistent with that employed prior to the Closing. Buyer further agrees that it shall not advertise or hold itself out as "Agere," "Agere Systems," "Lucent," "Lucent Technologies" or an Affiliate thereof after the Closing.

(b) Notwithstanding anything to the contrary in the foregoing, Buyer may continue to use the mask works and molds for products provided to Buyer hereunder or under the Intellectual Property Agreement notwithstanding that the use of such mask works or molds will imprint an Agere ▇▇▇▇ on such product and will not imprint Buyer's name or ▇▇▇▇ on such product; provided that only in the event that Buyer otherwise replaces or repairs any such mask work or mold shall Buyer remove the Agere Marks from such replacement or repaired mask work or mold and insert the name or ▇▇▇▇ of Buyer on such replacement or repaired mask work or mold.

5.9 Non-Solicitation of Employees

(a) None of Seller, any of its controlled Affiliates or any of their respective representatives will at any time prior to two years from the Closing Date, directly or indirectly, (i) solicit the employment of any Transferred Employee, (ii) hire any Transferred Employee, or (iii) continue to employ or employ a Business Employee, in each case, who refuses Buyer's offer of employment and does not become a Transferred Employee, in each case, without Buyer's prior written consent. For purposes of this Section 5.9(a), the term "solicit the employment" shall not be deemed to include generalized searches for employees through media advertisements, employment firms or otherwise that are not focused on Persons employed by Buyer, its Affiliates or any successor. This restriction shall not apply to any Transferred Employee whose employment with Buyer or its successor is involuntarily terminated by Buyer or its successor after the Closing. Solicitation of employment shall be deemed to occur if the Persons who perform such solicitation have knowledge of the existence of this Agreement or if such Persons have no knowledge of the existence of this Agreement but Seller's employees with knowledge of this Agreement have advance knowledge of any such solicitation. Seller shall use its reasonable commercial efforts to communicate the restrictions imposed by this Section 5.9(a) to all Persons who would reasonably be expected to engage in such solicitations or make such offers of employment and instruct such Persons to comply with such restrictions.

(b) None of Buyer, any of its controlled Affiliates or any of their respective representatives will at any time prior to two years from the Closing Date, directly or indirectly, solicit the employment of any employee of Seller (other than Business Employees), in each case without Seller's prior written consent. For purposes of this Section 5.9(b), the term "solicit the employment" shall not be deemed to include generalized searches for employees through media advertisements, employment firms or otherwise that are not focused on Persons employed by Seller, its Affiliates or any successor. This restriction shall not apply to any employee whose employment with Seller is involuntarily terminated by Seller after the Closing. Solicitation of employment shall be deemed to occur if the Persons who perform such solicitation have knowledge of this Agreement or if such Persons have no knowledge of this Agreement but the Buyer's employees with knowledge of the existence of this Agreement have advance knowledge of any such solicitation. Buyer shall use its reasonable commercial efforts to communicate the restrictions imposed by this Section 5.9(b) to all Persons who would reasonably be expected to engage in such solicitations or make such offers of employment and instruct such Persons to comply with such restrictions.

5.10 Non-Competition

(a) Seller agrees that, as part of the consideration for the payment of the Purchase Price, for the period of five (5) years immediately following the Closing Date in the case of items (b)(i) and (b)(ii) below, and for the period of three (3) years immediately following the Closing Date in the case of item (b)(iii) below, neither Seller nor any of its controlled Affiliates will, directly or indirectly, for its own benefit or as agent of another, carry on or own, manage or operate, perform, participate in, control the management or operation of, or allow its name to be used as a brand in or for, or have any ownership interest in, any Competing Business (i) in the County of Santa Clara, California, (ii) in the State of California, (iii) in the County of Washington, Oregon, (iv) in the State of Oregon, (v) in the County of Lehigh, Pennsylvania, (vi) in the State of Pennsylvania, (vii) in the United States of America or (viii) anywhere else in the world.

(b) For purposes of this Section 5.10, a "Competing Business" shall mean the design, manufacture, support, marketing or sale of (or the investment in or acquisition of any manufacturer of) any "stand alone" integrated circuit comprising (i) a general purpose array of logic gates (whether AND arrays or OR arrays) which can be interconnected by programming a matrix of interconnect lines between the logic gates, including any accompanying circuitry to provide I/O buffer control and protection, programming control and data path, embedded memory and other embedded subsidiary circuitry, timing control and distribution clocking, voltage control and regulation, and chip protection functions (a "Programmable Logic Device"); or (ii) a general purpose array of logic blocks built from basic logic gates or LUTs (Look Up Tables) which can be interconnected by programming a matrix of interconnect lines between the logic blocks, including any accompanying circuitry to provide I/O buffer control and protection, programming control and data path, embedded memory and other embedded subsidiary circuitry, timing control and distribution clocking, voltage control and regulation, and chip protection functions (a "Field Programmable Gate Array"); or (iii) Programmable Logic Device or Field Programmable Gate Array that is combined on an integrated circuit with other devices (including without limitation, networking communication, SERDES or other communication cores, memory, microprocessors, embedded analog circuitry, or other functions of integrated circuitry), regardless of whether any of the above devices is marketed as a Programmable Logic Device or Field Programmable Gate Array or FPSC; provided, however, that for the purposes of this clause (iii), a device in which the Programmable Logic Device or the Field Programmable Gate Array forms no more than 40% of the die area of such device shall not be considered within the scope of any such combined device.

(c) Nothing contained in this Section 5.10 shall (i) limit Seller or its Affiliates (A) from acquiring (including through a merger) or investing in any business, development arrangement or joint venture in which a Competing Business constitutes, represents or is responsible for not more than 25% of the revenues or earnings of such business, development arrangement or joint venture, or (B) from, directly

or indirectly, holding or making investments in securities of any business so long as Seller's direct or indirect holdings do not exceed 5% of the outstanding equity securities thereof, or (C) from incorporating, combining or using Third Party standard, commercially available Programmable Logic Devices or Field Programmable Gate Arrays in the form of discrete chips in Seller's products, or (ii) apply to any Person who acquires, directly or indirectly, the equity securities of, or control of, Seller or to the activities of any Person merging with or into Seller as conducted prior to such merger by any Person merging with or into Seller.

(d) Seller recognizes and agrees that compliance with the covenant contained in this Section 5.10 is necessary to protect Buyer, and that a breach by Seller of any of the covenants set forth in this Section 5.10 could cause irreparable harm to Buyer, that Buyer's remedies at law in the event of such breach would be inadequate, and that, accordingly, in the event of such breach, a restraining order or injunction or both may be issued against Seller without the requirement that Buyer post a bond, in addition to any other rights and remedies which are available to Buyer. If this Section 5.10 is more restrictive than permitted by the Laws of any jurisdiction in which Buyer seeks enforcement hereof, this Section 5.10 shall be limited to the extent required to permit enforcement under such Laws. In particular, the Parties intend that the covenants contained in the preceding portions of this Section 5.10 shall be construed as a series of separate covenants, one for each location specified. Except for geographic coverage, each such separate covenant shall be deemed identical in terms. If, in any judicial proceeding, a court shall refuse to enforce any of the separate covenants deemed included in this Section 5.10, then such unenforceable covenant shall be deemed eliminated from these provisions for the purpose of those proceedings to the extent necessary to permit the remaining separate covenants to be enforced. If any court of competent jurisdiction shall determine the foregoing covenant to be unenforceable with respect to the term or the scope of the subject matter or geography covered thereby, then such covenant shall nevertheless be enforceable by such court against the other party upon such shorter term or within such lesser scope as may be determined by such court to be reasonable and enforceable.

5.11 No Negotiation or Solicitation

Prior to the Closing Date, Seller and its Affiliates will not (and Seller will cause each of its employees, officers, directors, representatives and agents not to) (a) solicit, initiate, consider, entertain, encourage or accept the submission of any proposal or offer from any third party relating to the direct or indirect acquisition of the FPGA/FPSC Business or (except to the extent permitted by Section 5.2) any portion of the Purchased Assets, or (b) participate in any discussions or negotiations (and as of the date hereof, Seller shall immediately cease any discussions or negotiations that are ongoing) regarding, furnish any information with respect to, assist or participate in, or facilitate in any other manner any effort or attempt by any third party to do or seek any of the foregoing. Seller will notify Buyer promptly if any third party makes any proposal, offer, inquiry or contact with respect to any of the foregoing (including the terms thereof and the identity of such third party subject to any existing applicable confidentiality agreement or applicable Law) within two Business Days after receipt of any such offer or proposal.

5.12 Customer Commitments

Schedule 5.12 contains a list of customer commitments of the FPGA/FPSC Business (the "Customer Commitments"). Buyer agrees that following the Closing Date it shall use reasonable commercial efforts to continue to honor and perform such Customer Commitments. If (i) Seller fails to perform its obligations under the Collateral Agreements in a manner and at a level sufficient to permit Buyer to satisfy its obligations under this Section 5.12, or (ii) Buyer reasonably determines that it is likely to incur liability to a Third Party, including in connection with infringement of such third party's Intellectual Property Rights, then Buyer shall be excused from its obligations under this Section 5.12.

5.13 Recording of Patents

Not later than the Closing Date, Seller will record in the United States Patent and Trademark Office, at its own expense, any assignment, grant or conveyance, not previously recorded therein, by which it acquired ownership or any right to convey from a party other than a party to this Agreement, any of the Assigned Patents, as such term is defined in the Intellectual Property Agreement.

5.14 Assignment of FPGA Software License

In the event that the Closing occurs prior to December 15, 2001, on December 15, 2001, Seller shall assign all of its right, title and interest in and under the FPGA Software License Agreement, dated as of December 14, 1995 ("NeoCAD License"), among NeoCAD, Inc., Xilinx, Inc. and AT&T Corp.

5.15 Relocation of Certain Employees of the FPGA/FPSC Business

On or before the Closing Date, the Business Employees at the Premises located in Allentown, Pennsylvania shall be relocated by Seller, at Seller's sole cost and expense, to the Premises covered by the Sublease. Premises covered by the Sublease, and the furniture, equipment and work spaces shall be substantially similar to and of comparable quality as the Premises currently occupied by the Business Employees located in Allentown, Pennsylvania as of the date hereof.

5.16 Third Party Confidentiality Agreements

On or prior to the Closing Date, Seller shall provide Buyer with originals, or true, correct and redacted copies of all confidentiality agreements pursuant to which, since December 31, 2000, in connection with the proposed sale of the FPGA/FPSC Business or any material portion thereof, Seller or any of its Affiliates has disclosed on a confidential basis any confidential or proprietary information of, or relating to, the FPGA/FPSC Business to any Third Party. Within two Business Days after the date hereof, Seller shall request that all parties (other than any party with whom Seller is actively engaged in negotiations with respect to a potential business combination or other similar transaction not related to the FPGA/FPSC Business) who received any such confidential or proprietary information of or relating to the FPGA/FPSC Business either return or destroy such confidential or proprietary information in accordance with the provisions of the applicable confidentiality agreement.

5.17 Advice of Changes

Each party will promptly advise the other party in writing of (i) any event known to such party that would render any of its representations or warranties contained in this Agreement, if made on or as of the date of such event or the Closing Date, untrue or inaccurate in any material respect, (ii) any change, condition or event that has had or could reasonably be expected to have a Material Adverse Effect, or (iii) any failure of by such party to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied hereunder.

Seller shall process and approve product warranty claims, product recalls, excess or obsolete product returns and stock rotations and perform warranty and recall work required after the Closing for products sold or consigned by the FPGA/FPSC Business on or prior to the Closing Date in substantially the same manner as the FPGA/FPSC Business did on or prior to the Closing Date. In the event that Seller requires Buyer's assistance in performing any such activities, Buyer agrees to provide such assistance on a transition basis in accordance with the terms and conditions of the Transition Services Agreement.

5.19 Assistance with Nonassignable Licenses

Upon Buyer's request from the date hereof through the date 90 days after the Closing, Seller shall assist Buyer in obtaining, at Buyer's sole expense, a license to third party Intellectual Property that was licensed to Seller for use in operation of the FPGA/FPSC Business if such Intellectual Property was licensed to Seller pursuant to a Nonassignable License or will not be sublicensed by Seller to Buyer in connection with the transactions contemplated by this Agreement; provided, however, that the

foregoing obligation of Seller shall be limited to assisting in situations where, as between Buyer and Seller, Seller is best situated to facilitate Buyer obtaining the relevant license (e.g., where the relevant Intellectual Property is not generally commercially available).

6. Confidential Nature of Information

6.1 Confidentiality Agreement

Buyer and Seller agree that the Confidentiality Agreement shall continue to apply to (a) all documents, materials and other information that it shall have obtained regarding the other party or its Affiliates during the course of the negotiations leading to the consummation of the transactions contemplated hereby (whether obtained before or after the date of this Agreement), any investigations made in connection therewith and the preparation of this Agreement and related documents, and (b) all analyses, reports, compilations, evaluations and other materials prepared by Buyer or its counsel, accountants or financial advisors that contain or otherwise reflect or are based upon, in whole or in part, any of the provided information; provided, however, that, the Confidentiality Agreement shall terminate as of the Closing and shall be of no further force and effect thereafter with respect to information of Seller or an Affiliate of Seller the ownership of which is transferred to Buyer.

9.2 General Agreement to Indemnify

(a) Seller and Buyer shall indemnify, defend and hold harmless the other party hereto, and Affiliates thereof, and any director, officer or employee of such other party or Affiliates thereof (each an "Indemnified Party") from and against any and all claims, actions, suits, proceedings, liabilities, obligations, losses, damages, amounts paid in settlement, penalties, fines, interest, costs and expenses (including reasonable attorney's fees, court costs and other out-of-pocket expenses incurred in investigating, preparing or defending the foregoing) (collectively, "Losses") incurred or suffered by any Indemnified Party arising out of, resulting from, or relating to: (i) any failure of any representation or warranty of the Indemnifying Party to have been true and correct when made or deemed made as of the Closing Date, or at such different date or period specified for such representation or warranty; or (ii) the breach by such party of any covenant or agreement of such party contained in this Agreement to the extent not waived by the other party.

(b) Seller further agrees to indemnify and hold harmless any Indemnified Party of Buyer from and against any Losses incurred or suffered by such Indemnified Party of Buyer arising out of, resulting from, or relating to: (i) any of the Excluded Liabilities; (ii) Seller's failure to comply with applicable Bulk Sales Laws notwithstanding the waiver contained in Section 2.9; and (iii) any claims with respect to, or arising out of, any Business Employee in connection with any Benefit Plan or such Business Employee's employment or termination thereof with Seller or any of its Affiliates and any Liabilities that are obligations of the Seller or any of its Affiliates under Section 5.4.

(c) Buyer further agrees to indemnify and hold harmless any Indemnified Party of Seller from and against any Losses incurred or suffered by such Indemnified Party of Seller arising out of, resulting from, or relating to: (i) any of the Assumed Liabilities; (ii) medical, health or disability claims of any Transferred Employee under any benefit plan of Buyer or its Affiliates; (iii) any Liability of Buyer with respect to FPGA/FPSC Business or the Purchased Assets, solely with regard to conditions or events occurring after the Closing, in each case as conducted or used by Buyer after the Closing; and (iv) any Liabilities of Buyer with respect to, or arising out of, the employment by Buyer or the termination of employment by Buyer of any Transferred Employee after the Closing.

(d) Amounts payable in respect of the parties' indemnification obligations shall be treated as an adjustment to the Purchase Price. Buyer and Seller agree to use their reasonable commercial efforts to cooperate in the preparation of a supplemental Asset Acquisition Statement as required by Section 5.3 and Treasury Reg. § 1.1060-1(e)(1)(ii)(B) as a result of any adjustment to the Purchase Price pursuant to the preceding sentence. Whether or not the Indemnifying Party chooses to defend or prosecute any Third-Party Claim, both parties hereto shall cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be reasonably requested in connection therewith or as provided in Section 5.1.

(e) The amount of the Indemnifying Party's liability under this Agreement shall be net of any applicable insurance proceeds (reduced by the incremental costs of any increase in premiums related to such receipt of proceeds) actually received by, and Tax savings (net of all Tax costs and other effects that would result from any such Tax savings, including the positive and negative effects on any Tax attributes of Buyer), that actually reduce the overall impact of the Losses upon, the Indemnified Party. In computing the amount of any such Tax savings, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnity payment hereunder or the incurrence of any payment of any indemnified Loss. Notwithstanding this Section 9.2(e), in no event shall any Indemnified Party be required to take any action, or forebear from exercising any right, with respect to its Taxes or the filing of its Returns. The indemnification obligations of each party hereto under this Article 9 shall inure to the benefit of each Indemnified Party of the other party hereto on the same terms as are applicable to such other party.

(f) The Indemnifying Party's liability for all claims made under Section 9.2(a)(i) shall be subject to the following limitations: (i) the Indemnifying Party shall have no liability for such claims until the aggregate amount of the Losses incurred shall exceed $1,500,000, in which case the Indemnifying Party shall be liable for all Losses starting from the first dollar of such Losses, and (ii) the Indemnifying Party's aggregate liability for all such claims shall not exceed $100,000,000. Notwithstanding the above provisions of this Section 9.2(f), the limitations provided in this Section 9.2(f) shall not apply to (i) any claim for fraud or intentional misrepresentation, or (ii) any claim for breach of any agreement or covenant contained herein.

(g) The indemnification provided in this Article 9 shall be the sole and exclusive remedy after the Closing Date for damages available to the parties to this Agreement for breach of any of the covenants, agreements, representations or warranties contained herein; provided, however, this exclusive remedy for damages does not preclude a party from (i) bringing an action for specific performance or other equitable remedy for a breach of covenant or agreement under this Agreement, or (ii) pursuing remedies under applicable Law for fraud or intentional misrepresentation.

(h) Notwithstanding anything contained in this Agreement to the contrary, no party shall be liable to the other party for any indirect, special, punitive, exemplary or consequential loss or damage (including any loss of revenue or profit) arising out of this Agreement, provided, however, that the foregoing shall not be construed (i) to preclude recovery by the Indemnified Party in respect of Losses directly incurred from Third Party Claims and (ii) shall not apply to any remedies under applicable Law for fraud or intentional misrepresentation. Both parties shall mitigate their damages as may be required by applicable Law.

(i) The rights to indemnification under this Section 9.2 shall not be subject to set-off for any claim by the Indemnifying Party against any Indemnified Party, whether or not arising from the same event giving rise to such Indemnified Party's claim for indemnification.

9.3 General Procedures for Indemnification

(a) The Indemnified Party seeking indemnification under this Agreement shall promptly notify in writing the party against whom indemnification is sought (the "Indemnifying Party") of the assertion of any claim, or the commencement of any action, suit or proceeding by any third party, in respect of which indemnity may be sought hereunder and shall give the Indemnifying Party such information with respect thereto as the Indemnifying Party may reasonably request, but failure to give such notice shall not relieve the Indemnifying Party of any liability hereunder (unless and to the extent that the Indemnifying Party has suffered prejudice by such failure). The Indemnifying Party shall have the right, but not the obligation, exercisable by written notice to the Indemnified Party within thirty (30) days of receipt of notice from the Indemnified Party of the commencement of or assertion of any claim, action, suit or proceeding by a third party in respect of which indemnity may be sought hereunder (a "Third-Party Claim"), to assume the defense and control the settlement of such Third-Party Claim (with counsel reasonably acceptable to the Indemnified Party) that (i) involves (and continues to involve) solely money damages, or (ii) involves (and continues to involve) claims for both money damages and equitable relief against the Indemnified Party that cannot be severed, where the claims for money damages are the primary claims asserted by the third party and the claims for equitable relief are incidental to the claims for money damages and, such equitable relief, if reasonably expected to be awarded, would not be reasonably expected to be material to Buyer; provided, however, that the Indemnifying Party shall not impair the defense of the Indemnified Party with respect to any claims for equitable relief against the Indemnified Party. Failure by the Indemnifying Party to so notify the Indemnified Party shall be deemed a waiver by the Indemnifying Party of its right to assume the defense of such Third-Party Claim.

(b) The Indemnifying Party or the Indemnified Party, as the case may be, shall have the right to participate in (but not control), at its own expense, the defense of any Third-Party Claim that the other is defending, as provided in this Agreement.

(c) The Indemnifying Party, if it has assumed the defense of any Third-Party Claim as provided in this Agreement, shall not consent or agree to a compromise or settlement of, or the entry of any judgment arising from, any such Third-Party Claim without the Indemnified Party's prior written consent (which consent shall not be unreasonably withheld subject to the next sentence) unless such settlement or judgment relates solely to monetary damages. The Indemnifying Party shall not, without the Indemnified Party's prior written consent, enter into any compromise or settlement that (i) commits the Indemnified Party to take, or to forbear to take, any action, or (ii) does not provide for a complete written release by such third party of the Indemnified Party. The Indemnified Party shall have the sole and exclusive right to settle any Third-Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third-Party Claim involves equitable or other non-monetary relief against the Indemnified Party, and shall have the right to settle any Third-Party Claim involving money damages for which the Indemnifying Party has not assumed the defense pursuant to this Section 9.3 with the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

(d) In the event an Indemnified Party shall claim a right to payment pursuant to this Agreement, such Indemnified Party shall send written notice of such claim to the Indemnifying Party; but failure to give such notice shall not relieve the Indemnifying Party of any liability hereunder (unless and to the extent that the Indemnifying Party has suffered prejudice by such failure). Such notice shall specify the basis for such claim, the amount thereof, if known, and the method of computation thereof, all with reasonable particularity and shall contain a reference to the provisions of this Agreement in respect of which such a claim shall have been incurred. Such notice shall be given promptly after the Indemnified Party becomes aware of the basis for each such a claim. The Indemnifying Party shall, within thirty (30) days after receipt of such notice of an indemnified Loss, and subject to the limitations set forth in Section 9.2, (i) pay or cause to be paid to the Indemnified Party the amount of such Loss specified in such notice which the Indemnifying Party does not contest, or (ii) notify the Indemnified Party if it wishes to contest the existence or amount of part or all of such a Loss by stating with particularity the basis upon which it contests the existence or amount thereof.

This Agreement shall be binding upon and inure to the benefit of and be enforceable by the successors, legal representatives and permitted assigns of each party hereto. The

provisions of this Agreement are severable, and in the event that any one or more provisions are deemed illegal or unenforceable the remaining provisions shall remain in full force and effect unless the deletion of such provision shall cause this Agreement to become materially adverse to either party, in which event the parties shall use reasonable commercial efforts to arrive at an accommodation that best preserves for the parties the benefits and obligations of the offending provision.

10.5 Governing Law

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK IRRESPECTIVE OF THE CHOICE OF LAWS PRINCIPLES OF THE STATE OF NEW YORK, AS TO ALL MATTERS, INCLUDING MATTERS OF VALIDITY, CONSTRUCTION, EFFECT, ENFORCEABILITY, PERFORMANCE AND REMEDIES.

Except for such press release, neither Seller nor Buyer shall, without the approval of the other, make any press release or other public announcement concerning the existence of this Agreement or the terms of the transactions contemplated by this Agreement, except as and to the extent that any such party shall be so obligated by Law, in which case the other party shall be advised and the parties shall use their reasonable commercial efforts to cause a mutually agreeable release or announcement to be issued; provided, however, that the foregoing shall not apply to communications or disclosures necessary to comply with accounting rules, stock exchange or market rules or federal securities or labor relations Law disclosure obligations.

10.9 No Third-Party Beneficiaries

(c) Failure of Seller Condition.
