Prior to Closing, Seller will deliver to Purchaser a Transmitted Copy of the Assignment of Patent Rights in the form set forth in Exhibit B prior to Closing and will deliver or cause to be delivered to Seller’s agent the original Assignment of Patent Rights in the form set forth in Exhibit B (as may be updated based on Purchaser’s review pursuant to paragraph 3.1).

(a) inventions, invention disclosures, and discoveries specifically disclosed in any of the Patents;

(b) rights to apply in any or all countries of the world for patents, certificates of invention, utility models, industrial design protections, design patent protections, or other governmental grants or issuances of any type related to any of the Patents and the inventions, invention disclosures, and discoveries specifically disclosed therein;

(c) causes of action (whether known or unknown or whether currently pending, filed, or otherwise) and other enforcement rights under, or on account of, any of the Patents and/or the rights described in subparagraph 4.2(b), including, without limitation, all causes of action and other enforcement rights for (i) damages, (ii) injunctive relief, and (iii) any other remedies of any kind for past, current and future infringement; and

(d) rights to collect royalties or other payments under or on account of any of the Patents and/or any of the foregoing.

4.3 Assignment of Rights in Certain Assets. Upon the Closing, Seller hereby sells, assigns, transfers, and conveys to Purchaser all Seller’s right, title, and interest in and to the Abandoned Assets.

Page 4

4.4 License Back to Seller under Patents. Upon the Closing, Purchaser hereby grants to Seller and its Affiliates, under the Patents, and for the lives thereof, a royalty-free, non-exclusive, non-sublicensable right and license (“Seller License”) to practice the methods and to make, have made, use, distribute, lease, sell, offer for sale, import, export, develop and otherwise dispose of and exploit any Seller products and products of Affiliates of Seller covered by the Patents (“Covered Products”). The Seller License shall apply to the reproduction and subsequent distribution of Covered Products under Seller’s trademarks and brands, in substantially identical form as they are distributed by the Seller, by authorized agents of the Seller such as a distributor, replicator, VAR or OEM. The Seller License is nontransferable (by operation of law or otherwise) except as set forth in paragraph 4.5. The Seller License, as to any Affiliate of Seller, will terminate as to such Affiliate if and when such Affiliate ceases to meet the requirements of being an Affiliate of Seller.

4.5 Limitation on Transferability of Seller License. The Seller License may be assigned by Seller once and only once within two (2) years of the Effective Date (the “Unrestricted Assignment Period”) without restriction on the assignee (“Assignee”) other than such restrictions as are set forth in paragraph 4.4 above (provided that Seller gives Purchaser prompt written notice of the assignment within fifteen (15) days after such assignment), and after such assignment the assignee and its Affiliates shall have all license rights granted hereunder to Seller and its Affiliates, respectively, subject to the restrictions set forth herein. After the earlier of the expiration of the Unrestricted Assignment Period or the assignment of the Seller License in accordance with the preceding sentence, the Seller License may be transferred only to a transferee that is purchasing the entire business line of the Covered Products of Seller or the Assignee, as applicable (a “Permitted Transferee”). In the event of such a transfer(a “Transfer”), the Permitted Transferee and its Affiliates shall have all license rights granted hereunder to Seller and its Affiliates, respectively, subject to the restrictions set forth herein. Further, in the event of a Transfer, the Covered Products will be limited to the products that had been commercially released by Seller and, if applicable, the Assignee, or that are in the prototype phase of development and are intended for commercial release solely by or on behalf of Seller or the Assignee, as applicable, prior to the effective date of such Transfer and the merely incremental differences of such products, and the Covered Products will not include, and in no event will the Seller License extend to, any other products, processes or services of (x) a Permitted Transferee, (y) any affiliate (other than Seller, the Assignee or an Affiliate of the Permitted Transferee, as applicable) of such purchaser or successor, or (z) any other person. Seller or the Assignee, as applicable, shall, within thirty (30) days after a Transfer, provide Purchaser with written notice of such Transfer, which notice will contain: (i) the effective date of the Transfer, (j) a description of the transaction through which the Transfer occurred, and (k) detailed information regarding the respective products, processes and services of Seller, the Assignee, the Permitted Transferee, and the purchasing entity, as applicable, as of the effective date of the Transfer, and the Seller License will immediately terminate in the event that Seller or the Assignee, as applicable, fails to provide such notice as and when set forth above. The Permitted Transferee may not transfer the Seller License (by operation of law or otherwise). The Seller License will immediately terminate upon any attempted transfer (by operation of law or otherwise) that is not in strict conformance with this paragraph 4.5, and any such attempted transfer will be void.

4.6 Right to Sue Visionary Solutions, Inc. for Breach of Contract. Notwithstanding paragraph 4.2, Seller will retain, and will not transfer in whole or in part to Buyer, the sole right to sue Visionary Solutions, Inc. (“Visionary Solutions”) for breach of contract under the Technology License Agreement between Seller and Visionary Solutions dated as of December 11, 2001. The right retained by Seller under this paragraph 4.6 does not include the right to bring against Visionary Solutions any claim other than a breach of contract claim, and Seller will have no right to sue Visionary Solutions or any other party for infringement of any of the Assigned Patent Rights.

5.	ADDITIONAL OBLIGATIONS

5.1 Further Cooperation. At the reasonable request of Purchaser, Seller will execute and deliver such other instruments and do and perform such other acts and things as may be necessary or desirable for effecting completely the consummation of the transactions contemplated hereby, including, without limitation, execution, acknowledgment, and recordation of other such papers, and using commercially reasonable efforts to obtain the same from the respective inventors, as necessary or desirable for fully perfecting and conveying unto Purchaser the benefit of the transactions contemplated hereby. To the extent any attorney-client privilege or the attorney work-product doctrine applies to any portion of the Patent History Files, Seller will ensure that, if any such portion of the Patent History File remains under Seller’s possession or control after Closing, it is not disclosed to any third party unless (a) disclosure is ordered by a court of competent jurisdiction, after all appropriate appeals to prevent disclosure have been exhausted, and (b) Seller gave Purchaser prompt notice upon learning that any third party sought or intended to seek a court order requiring the disclosure of any such portion of the Patent History File. In addition, Seller will continue to prosecute, maintain, and defend the Patents at its sole expense until the Closing.

5.2 Payment of Fees. Seller will pay any maintenance fees, annuities, and the like due or payable on the Patents until the Closing. For the avoidance of doubt, Seller shall pay any maintenance fees for which the fee is payable (e.g., the fee payment window opens) on or prior to the Closing even if the surcharge date or final deadline for payment of such fee would be within one month after the Closing.

6.	REPRESENTATIONS AND WARRANTIES OF SELLER

Seller hereby represents and warrants to Purchaser as follows that, as of the Effective Date and as of the Closing:

6.1 Authority. Seller has the full power and authority and has obtained all third party consents, approvals, and/or other authorizations required to enter into this Agreement and to carry out its obligations hereunder, including, without limitation, the assignment of the Assigned Patent Rights to Purchaser.

6.2 Title and Contest. Seller owns all right, title, and interest to the Assigned Patent Rights, including, without limitation, all right, title, and interest to sue for infringement of the Patents. Seller has obtained and properly recorded previously executed assignments for the Patents as necessary to fully perfect its rights and title therein in accordance with governing law and regulations in each respective jurisdiction. The Assigned Patent Rights are free and clear of all liens, claims, mortgages, security interests or other encumbrances, and restrictions. There are no actions, suits, investigations, claims, or proceedings threatened, pending, or in progress relating in any way to the Assigned Patent Rights. There are no existing contracts, agreements, options, commitments, proposals, bids, offers, or rights with, to, or in any person to acquire any of the Assigned Patent Rights.

6.3 Existing Licenses. No licenses under the Patents, or interest or rights in any of the Assigned Patent Rights, have been granted or retained by Seller, any prior owners, or inventors.

Page 6

6.4 Restrictions on Rights. Purchaser will not be subject to any covenant not to sue or similar restrictions on its enforcement or enjoyment of the Assigned Patent Rights or the Abandoned Assets as a result of any prior transaction related to the Assigned Patent Rights or the Abandoned Assets.

6.5 Validity and Enforceability. None of the Patents or the Abandoned Assets (other than Abandoned Assets for which abandonment resulted solely from unpaid fees and/or annuities) has ever been found invalid, unpatentable, or unenforceable for any reason in any administrative, arbitration, judicial or other proceeding, and Seller does not know of and has not received any notice or information of any kind from any source suggesting that the Patents may be invalid, unpatentable, or unenforceable. To the extent “small entity” fees were paid to the United States Patent and Trademark Office for any Patent, such reduced fees were then appropriate because the payor qualified to pay “small entity” fees at the time of such payment and specifically had not licensed rights in the any Patent to an entity that was not a “small entity.”

6.6 Conduct. To Seller’s knowledge formed after reasonable due diligence and investigation, Seller or its agents or representatives have not engaged in any conduct, or omitted to perform any necessary act, the result of which would invalidate any of the Patents or hinder their enforcement, including, without limitation, misrepresenting Seller’s patent rights to a standard-setting organization.

6.7 Enforcement. Seller has not put a third party on notice of actual or potential infringement of any of the Patents or the Abandoned Assets. Seller has not invited any third party to enter into a license under any of the Patents or the Abandoned Assets. Seller has not initiated any enforcement action with respect to any of the Patents or the Abandoned Assets.

6.8 Patent Office Proceedings. None of the Patents or the Abandoned Assets has been or is currently involved in any reexamination, reissue, interference proceeding, or any similar proceeding, and no such proceedings are pending or threatened.

6.9 Fees. All maintenance fees, annuities, and the like due or payable on the Patents as set forth in paragraph 5.2 have been timely paid on or before the date of the Closing. Exhibit E sets forth all future payment deadlines known to Seller after reasonable due diligence and investigation with respect to the Patents, and Seller will update Exhibit E to cause it to be current as of Closing.

6.10. Abandoned Assets. According to each applicable patent office, each of the Abandoned Assets has expired, lapsed, or been abandoned or deemed withdrawn.

7.	REPRESENTATIONS AND WARRANTIES OF PURCHASER

Purchaser hereby represents and warrants to Seller as follows that, as of the Effective Date and as of the Closing:

7.1 Purchaser is a limited liability company duly formed, validly existing, and in good standing under the laws of the jurisdiction of its formation.

7.2 Purchaser has all requisite power and authority to (i) enter into, execute, and deliver this Agreement and (ii) perform fully its obligations hereunder.
