5.1 Closing and Delivery on Closing Date. No later than two (2) business days prior to the date on which the closing of the Merger (as defined below) or the merger under the Alternate Merger Agreement (as defined below) is expected to occur, Seller shall deliver to Purchaser written notice stating that the closing of the Merger is expected to occur on such date, provided, that if Purchaser has elected to go forward with this Agreement pursuant to Section 6.1(b) in circumstances in which there is no Merger Agreement or Alternate Merger Agreement, the Closing shall take place two (2) business days following the satisfaction of all the conditions to Closing set forth in Section 5.3 at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, 1 Beacon Street, Boston, Massachusetts 02108.

In the event that Purchaser has elected to continue this Agreement in full force and effect in accordance with Section 6.1(b) in circumstances involving an Alternate Merger Agreement, Closing shall occur

5

on the same day as the closing of the merger under the Alternate Merger Agreement, unless otherwise waived by Purchaser in which event the time of the Merger shall be as consented to by Purchaser, if all of the conditions to Closing set forth in Section 5.3 shall have been satisfied or, to the extent permitted under applicable Law, waived (other than those conditions that by their nature can only be satisfied at Closing, but subject to the satisfaction or waiver of those conditions at Closing); provided that such Closing Date shall be at least two (2) business days after all of such conditions in Section 5.3 have been satisfied or waived; provided, further, that if the conditions to Closing are not satisfied on such day, Closing shall occur on the second (2nd) business day following the first day on which the conditions to Closing shall have been satisfied or, to the extent permitted under applicable Law, waived (other than those conditions that by their nature can only be satisfied at Closing, but subject to the satisfaction or waiver of those conditions at Closing).

Seller shall deliver to Purchaser no later than five (5) business days prior to Closing hereunder the final version of Exhibit C that has been updated through the Closing Date in accordance with the immediately preceding sentence for Purchaser’s information only; it being understood and agreed that such updated Exhibit C

6

shall not in any way affect, modify or qualify the representations and warranties set forth in Section 7 or the conditions to Closing set forth in Section 5.3(g). Assuming Seller has provided Purchaser with the written notice referenced in the first sentence of this Section 5.1, on the Closing Date, prior to the Closing, Purchaser shall deliver to Seller a written notice confirming that Purchaser is prepared to, and at the Closing will have sufficient available funds to, consummate the transactions contemplated by Section 2.1 and Section 2.2 pursuant to the terms of this Agreement, subject to the satisfaction at Closing of the conditions to Closing set forth in Section 5.3.

(c) with respect to a party, the other party shall have, in all material respects, performed or complied with all agreements, obligations or covenants required to be performed or complied with by it under this Agreement at or prior to the Closing;

5.4 Allocation of Payment. Seller and Purchaser shall jointly prepare, within ninety (90) days after the Closing Date, a schedule allocating the Payment among the Assigned Patents (the “Allocation Schedule”), which allocation shall take into account the relative fair market values of the U.S. and non-U.S. Assigned Patents. Seller and Purchaser shall (a) reasonably cooperate with each other in preparing the Allocation Schedule, (b) promptly provide each other with any information reasonably requested by the other party to prepare the Allocation Schedule and (c) attempt in good faith to resolve any dispute with respect to the Allocation Schedule. If within ninety (90) days after the Closing Date, Seller and Purchaser are unable to resolve any dispute with respect to the Allocation Schedule, Seller and Purchaser, or, if applicable, the relevant members and affiliates of Purchaser, shall refer the dispute to a mutually agreeable, independent accounting firm of international standing (the “Accounting Firm”) for resolution within sixty (60) days. The Accounting Firm shall determine, based solely on written submissions by Seller

8

and Purchaser, or, if applicable, the relevant members and affiliates of Purchaser (and not by independent review) only those issues in dispute and shall render a written report as to the resolution of the dispute and the resulting Allocation Schedule. In resolving any disputed item, the Accounting Firm may not assign a fair market value to any Assigned Patent (i) greater than the greatest fair market value for such Assigned Patent claimed by any party or (ii) less than the smallest fair market value for such Assigned Patent claimed by any party. Each of Purchaser and Seller shall bear and be responsible for one-half of the fees, costs and expenses of the Accounting Firm. The Accounting Firm’s resolution will be binding on both Seller and Purchaser (and their respective affiliates) and will be incorporated into the Allocation Schedule. The Allocation Schedule shall be revised to take into account subsequent adjustments, if any, to the Payment. The Allocation Schedule derived pursuant to this Section 5.4 shall be binding on Seller and Purchaser (and their respective affiliates) for all tax reporting purposes, and neither Seller nor Purchaser shall agree to any proposed adjustment to the Allocation Schedule by any taxing authority without first giving the other party prior written notice and the opportunity to challenge such proposed adjustment.

5.5 Indemnity for Taxes of Seller. Seller shall indemnify, defend and hold harmless Purchaser and any of Purchaser’s direct or indirect owners (collectively, the “Purchaser Indemnified Parties”) for any taxes (of any kind or nature, whether federal, state, local, or foreign, and including any interest, penalties, and additions to tax) (a) of Seller for any taxable period, or portion thereof, that ends on or prior to the Closing Date or (b) imposed on the sale, transfer and assignment of the Assigned Patents to Purchaser as contemplated by this Agreement (including the portion of Transfer Taxes payable by Seller, but excluding the portion of Transfer Taxes payable by Purchaser, under Section 8.14(b)). Notwithstanding anything else to the contrary in this Agreement, the indemnity for taxes in this Section 5.5 shall survive until sixty (60) days after the expiration of the applicable statute of limitation.

5.6 Other Acquisition Proposals. Seller shall as promptly as reasonably practicable, and in any event within the earlier of (i) forty-eight (48) hours and (ii) one (1) business day after receipt, notify Purchaser orally and in writing of the receipt of any Acquisition Proposal or any inquiry, proposal, indication of interest or offer (whether in writing or otherwise) from any person (other than Purchaser) to acquire or license any of the Assigned Patents (collectively, a “Proposal”) and of the price and other material terms and conditions of each such Proposal (including the identity of the person making such Proposal) and of any changes or supplements thereto.

5.7 Merger Agreement Amendment. Seller shall not agree to the amendment of the conditions to, or the termination of, the Merger Agreement, or the amendment of any other provisions of the Merger Agreement, in each case that would adversely affect, impair or delay the rights of Purchaser hereunder in any material respect.

6.1 This Agreement will terminate (a) upon mutual written agreement of Purchaser and Seller, (b) automatically, without requirement of any action by either Seller or Purchaser, upon

9

the termination of the Merger Agreement in accordance with the terms of the Merger Agreement prior to the consummation of the Merger, provided that, notwithstanding the foregoing, in the event that Seller receives an Acquisition Proposal (within the meaning of the Merger Agreement as in effect on the Effective Date, or within the meaning of any comparable term in any amended version of the Merger Agreement after the Effective Date) that contemplates an acquisition of Seller other than by an acquirer whose acquisition proposal contemplates that Seller will retain all of the Assigned Patents, Seller will provide Purchaser with notice thereof, and if Purchaser provides written notice to Seller at any time within three (3) days following written notice from Seller that it has received such an Acquisition Proposal, that Purchaser elects to continue this Agreement, and Seller deems such Acquisition Proposal to be a Superior Proposal (within the meaning of the Merger Agreement as in effect on the Effective Date, or within the meaning of any comparable term in any amended version of the Merger Agreement after the Effective Date), this Agreement shall remain in full force and effect and shall not have been considered to have been terminated, and references contained in this Agreement to the “Merger Agreement” shall automatically be deemed to be to the Agreement and Plan of Merger (or other form of acquisition agreement) between Seller and the party from which Seller has accepted such Superior Proposal (the “Alternate Merger Agreement”); and provided further that notwithstanding the foregoing, in the event that the Merger Agreement is terminated for any other reason other than the receipt by Seller of an Acquisition Proposal (within the meaning of the Merger Agreement as in effect on the Effective Date, or within the meaning of any comparable term in any amended version of the Merger Agreement after the Effective Date) for all of Seller that Seller deems to be a Superior Proposal, Seller will provide Purchaser with notice thereof, and if Purchaser provides written notice to Seller, at any time within three (3) days following written notice from Seller that the Merger Agreement has been terminated, that Purchaser elects to continue this Agreement, this Agreement shall remain in full force and effect and shall not have been considered to have been terminated, and references contained in this Agreement to the “Merger Agreement” shall automatically be deemed to not have any force or effect; (c) by either party, upon written notice to the other party, if the Closing Date has not occurred on or prior to April 20, 2011, unless the April 20, 2011 date is extended under the terms of the Merger Agreement, in which event such date shall be as extended under the Merger Agreement; provided that if Purchaser elects to continue this Agreement in full force and effect following Seller’s termination of the Merger Agreement in accordance with its terms prior to consummation of the Merger to accept a Superior Proposal pursuant to the immediately preceding subclause (b), such date shall be extended to the outside termination date provided for in the Alternate Merger Agreement, as identified in good faith by Purchaser to Seller; provided, further that this termination right shall not be available to any party if its breach of this Agreement has been the cause of, or resulted in, the failure to consummate the transactions contemplated by this Agreement by the Closing Date, (d) by either party, upon written notice to the other party, if it will not be possible for the Closing Date to occur by the outside termination date applicable under subclause (c) above, provided that this termination right shall not be available to any party if its breach of this Agreement has been the cause of, or resulted in, the failure to consummate the transactions contemplated by this Agreement by the Closing Date, or (e) by either party, upon written notice to the other party, in the event the Closing occurs but the Merger does not occur immediately thereafter on the Closing Date, such notice to be given no later than the business day immediately succeeding the Closing Date (unless such timing of the Merger has been waived by Purchaser in which event the time of the Merger shall be as

10

consented to by Purchaser and the termination right in this subclause (e) shall be as consented to by Purchaser in connection with such waiver); provided that this termination right shall not be available to any party if its actions have been the cause of, or resulted in, the failure to consummate the transactions contemplated by the Merger Agreement by the Closing Date; provided, further, that in the event of such termination pursuant to subclause (e), Seller shall immediately return to Purchaser the Payment and the transactions contemplated by Sections 2.1 and 2.2 shall be null and void and Purchaser shall return any documents delivered thereby. In the event that Purchaser has elected to continue this Agreement pursuant to Section 6.1(b), Purchaser and Seller shall enter into a royalty-free, fully paid-up patent cross license for no additional consideration, effective as of Closing, with respect to all patents and patent applications owned or controlled by them on mutually acceptable terms that are no less favorable in the aggregate to either party than the terms of any other patent cross license offered by Purchaser to any other person (other than any member of Purchaser or an affiliate of any such member). The parties agree that the obligations of Seller pursuant to subclause (e) of this Section 6.1 shall be specific to the terms of such subclause (e) and Purchaser shall have the right to seek specific performance from the other party for failure to return the Payment under such subclause (e). If Seller terminates the Merger Agreement in accordance with its terms prior to the consummation of the Merger to accept a Superior Proposal or otherwise, Seller shall provide Purchaser written notice of such action no later than the time it notifies Sub of its decision to terminate the Merger Agreement.

6.2 Upon termination of this Agreement as provided in Section 6.1, this Agreement shall be deemed null and void and Purchaser will return all confidential materials provided by Seller within five (5) business days from the date of notice of termination; provided that (i) no such termination shall relieve any party from any damages, liabilities or obligations relating to any intentional breach of this Agreement prior to such termination, and the other party to this Agreement shall continue to have the right to pursue any and all remedies in respect of such breach following such termination and (ii) this Section 6.2 and Sections 8.2-8.18 shall survive any such termination and remain in full force and effect.

7.1 Seller hereby represents and warrants to Purchaser that, as of the date hereof and as of the Closing:

Seller has the right and authority, and has been duly authorized by all necessary corporate and other actions of Seller, to execute and deliver this Agreement and to perform its obligations hereunder and requires no third party consent, approval, and/or other authorization to execute and deliver this Agreement and to perform its obligations hereunder, including, without limitation, to assign the Assigned Patents to Purchaser. Neither the execution and delivery of this Agreement by Seller, nor the performance by Seller of its obligations hereunder, will (i) conflict with or result in any material breach or violation of any of the terms or conditions of, or constitute a default under, any instrument, contract or other agreement to which Seller is a party or by which Seller or any of the Assigned Patents is bound, (ii) result in the imposition of any Lien upon the Assigned Patents, (iii) conflict with or result in any breach

Seller shall not assign or delegate this Agreement or any of its rights or obligation under this Agreement, without the prior written consent of Purchaser, except in connection with the Merger by operation of law. Any such purported assignment or delegation by Seller without such prior written consent shall be null and void.

Seller and Purchaser agree to cooperate and take all actions reasonably requested by the other side (including, without limitation, all actions necessary to effect the electronic delivery of the Assigned Patents, in the manner and to the extent requested by Purchaser) to minimize the amount of Transfer Taxes payable under this Section 8.14(b).

18

8.15 Interim Operations of Seller. Between the Effective Date and the Closing Date, Seller agrees that it shall not, nor shall it permit any of its subsidiaries to, enter into any enforceable contract, agreement, commitment or arrangement that would make the representations and warranties of the Seller untrue or incorrect as of the Closing.

8.17 Specific Performance. Each party agrees that the failure of any other party to perform its agreements and covenants hereunder will cause irreparable damage to the first party and that the first party would not have any adequate remedy at law in such event.
