39

6.2Registration Rights.  The Company shall not grant any right of registration under the Securities Act relating to any of its securities to any Person other than the Purchaser if such rights would or could reasonably be expected to frustrate, impede or limit the Purchaser’s rights pursuant to the Registration Rights Agreement.

6.3Rule 144.  The Company shall file all reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as the Purchaser may reasonably request, all to the extent required to enable the Purchaser to sell the Common Stock into which the Note may be converted pursuant to and in accordance with Rule 144.  Such action shall include, but not be limited to, making available adequate current public information meeting the requirements of paragraph (c) of Rule 144.

Any director designated by the Purchaser to serve on any committee may designate as his or her alternate another director designated by the Purchaser.

The Board of Directors shall recommend the Certificate Amendment and such recommendation shall be included in the proxy statement filed with the Commission and disseminated to Company stockholders in connection with such stockholders meeting. The “Certificate Amendment” shall mean an amendment to the Certificate of Incorporation that, at the sole discretion of the Purchaser, (i) will provide that the Company expressly elects not to be governed by Section 203 of the DGCL and/or (ii) will provide that each member of the Board of Directors shall be elected annually for a one (1) year term.

42

reasonably informed of any actions or suits under this Section 6.10(b).  The Purchaser shall have the right, at its own cost, to participate in all decisions and actions concerning the validity of any Intellectual Property relating to or embodied in the Imagify Product, including the right to join as a party any such Action for infringement brought by or against the Company with respect to any Intellectual Property relating to or embodied in the Imagify Product where a defense or claim of patent invalidity or unenforceability has been or will be raised.  The Purchaser shall have the right to retain its own counsel, at its own expense, for the purpose of defending the validity or enforceability of any of the Intellectual Property relating to or embodied in the Imagify Product.

Miscellaneous Provisions

Section 7.1Indemnification.

(a)The Purchaser.  The Purchaser agrees to defend the Company, its Affiliates and their respective directors, officers, employees and agents at the Purchaser ‘s cost and expense, and shall indemnify and hold harmless the Company and its Affiliates and their respective directors, officers, employees and agents from and against any liabilities, losses, costs, damages, fees or expenses arising out of any Third Party claim relating to (i) any breach by the Purchaser of any of its representations, warranties or obligations pursuant to this Agreement or (ii) personal injury, property damage or other damage resulting from the development or commercialization by the Purchaser or its Affiliates or sublicensees of a product Covered by any of the Licensed Patent Rights.

(b)The Company.  The Company agrees to defend the Purchaser, its Affiliates and their respective directors, officers, employees and agents at the Company’s cost and expense, and shall indemnify and hold harmless the Purchaser and its Affiliates and their respective directors, officers, employees and agents from and against any liabilities, losses, costs, damages, fees or expenses arising out of any Third Party claim relating to any breach by the Company of any of its representations, warranties or obligations pursuant to this Agreement or (ii) personal injury, property damage or other damage resulting from the development or commercialization by the Company or its Affiliates or sublicensees of a product Covered by any of the Licensed Patent Rights.

(c)Claims for Indemnification.  A person entitled to indemnification under this Section 7.1 (an “Indemnified Party”) shall give prompt written notification to the person from whom indemnification is sought (the “Indemnifying Party”) of the commencement of any action, suit or proceeding relating to a Third Party claim for which indemnification may be sought or, if earlier, upon the assertion of any such claim by a Third Party (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a third-party claim as provided in this Section 7.1(c) shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice).  Within thirty (30) days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such action, suit, proceeding or claim with counsel reasonably satisfactory to the Indemnified Party.  If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense.  The Party not controlling such defense may participate therein at its own expense; provided that, if the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes, based on advice from counsel, that the Indemnifying Party and the Indemnified Party

13

have conflicting interests with respect to such action, suit, proceeding or claim, the Indemnifying Party shall be responsible for the reasonable fees and expenses of counsel to the Indemnified Party solely in connection therewith; provided, however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one counsel for all Indemnified Parties.  The Party controlling such defense shall keep the other Party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other Party with respect thereto.  The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned.  The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto or that imposes any liability or obligation on the Indemnified Party without the prior written consent of the Indemnified Party.

Section 7.2Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.  This Agreement shall be governed by and construed in accordance with the Requirements of Law of the State of Delaware without giving effect to the principles of conflict of laws.  Each of the parties hereto hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the courts of the State of Delaware or the United States District Court for the District of Delaware and the appellate courts having the jurisdiction with respect to appeals from such courts, for any action arising out of or relating to this Agreement (and agrees not to commence any action relating thereto except in such courts), and further agrees that service of any process, summons, notice or document by U.S. registered mail to its respective address set forth in this Agreement, or such other address as may be given by one or more parties to the other parties in accordance with the notice provisions of Section 7.5, shall be effective service of process for any action, suit or proceeding brought against it in any such court.  Each of the parties hereto hereby irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in the courts of the State of Delaware or the United States District Court for the District of Delaware and the appellate courts having the jurisdiction with respect to appeals from such courts, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action brought in any such court has been brought in an inconvenient forum.  Each of the parties irrevocably and unconditionally waives, to the fullest extent permitted by applicable Requirements of Law, any and all rights to trial by jury in connection with any action, suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Section 7.3Assignment.  Neither this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred by either Party without the prior written consent of the other Party (which consent shall not be unreasonably withheld); provided, however, that either Party may assign this Agreement and its rights and obligations hereunder without the other Party’s consent (a) in connection with the transfer or sale of all or substantially all of the business of such Party to a Third Party, whether by merger, sale of stock, sale of assets or otherwise or (b) to any Affiliate; provided that  no such assignment to an Affiliate shall relieve the assigning Party of its responsibilities for performance of its obligations under this Agreement.

14

Section 7.4Entire Agreement; Amendments.  This Agreement constitutes the entire agreement between the Parties with respect to the subject matter hereof, and supersedes all previous arrangements with respect to the subject matter hereof, whether written or oral.  Any amendment or modification to this Agreement shall be made in writing signed by both Parties.
