(b) The indemnifying Party shall have the right to defend the indemnified Party against the third party Action with counsel and other representatives of its choice so long as (i) the indemnifying Party shall notify the indemnified Party in writing within the 15 calendar day period after its receipt of notice of the third party Action; that it will indemnify the indemnified Party from and against any damages the indemnified Party may suffer arising out of the third party Action; and (ii) the indemnifying Party diligently conducts the defense of the third party Action in the reasonable opinion of the indemnified Party. In the event the indemnifying Party does not comply with clauses (i) or (ii) of the preceding sentence, the indemnified Party may defend against the third party Action, preserving its rights to indemnification hereunder including, without limitation, for the cost of such defense.

(c) So long as the indemnifying Party is diligently conducting the defense of the third party Action in accordance with Section 6.4(b) above, (i) the indemnified Party may retain separate co-counsel, at its sole cost and expense, and

participate in the defense of the third party Action, (ii) the indemnified Party shall not consent to the entry of any judgment or enter into any settlement with respect to the third party Action without the prior written consent of the indemnifying Party, which consent shall not be unreasonably withheld or delayed, (iii) the indemnified Party shall fully cooperate within reason with the indemnifying Party’s defense of such third party Action including, without limitation, providing any and all required information and documents and access to representatives of the indemnified Party with knowledge of issues relevant to the claim or litigation (any such activities required to discharge this obligation to cooperate shall be incurred at the sole expense of the indemnified Party), and (iv) the indemnifying Party shall not consent to the entry of any judgment or enter into any settlement with respect to the third party Action without the prior written consent of the indemnified Party, which consent shall not be unreasonably withheld or delayed.

(d) Notwithstanding any contradiction in Section 6.4 (a) —(c), an indemnified Party shall be entitled to assume the defense of any third party Action (and the indemnifying Party shall be liable for the reasonable fees and expenses incurred by the indemnified Party in defending such claim) if the third party Action seeks an order, injunction, or other equitable relief or relief for other than money damages against the indemnified Party, which the indemnified Party determines, after conferring with its counsel, cannot be separated from any related claim for money damages and which, if successful, would materially adversely affect the properties or the business of the indemnified Party; provided, however, if such equitable relief portion of such third party Action can be so separated from that for money damages, the indemnifying Party shall be entitled to assume the defense of the portion relating to money damages.

6.5 Threshold Amount. Indemnification claims for losses made by either party shall be available only if and to the extent the aggregate amount of all such claims made by such party exceeds $25,000.

7. Miscellaneous.

7.1. Public Announcement. Except as required by applicable Law or any Governmental Authority with competent jurisdiction, neither Party hereto, nor any of their respective Affiliates and representatives, shall issue any press release or make any public announcement or disclosure with respect to this Agreement or the transactions contemplated hereby without the prior written consent of the other Party hereto, which consent shall not be unreasonably withheld. The Seller and the Purchaser shall agree on the content of any press release announcing the execution of this Agreement and the consummation of the transactions contemplated hereby prior to any press release. Notwithstanding the foregoing, the Seller may publish such information as it reasonably believes is necessary to comply with federal and state law and any other regulatory requirements including the requirements of any stock exchange.

7.2. Amendment; Waiver. Neither this Agreement, nor any of the terms or provisions hereof, may be amended, modified, supplemented, or waived except by a written instrument signed by all of the Parties hereto (or, in the case of a waiver, by the Party granting such waiver). No waiver of any of the terms or provisions of this Agreement shall be deemed to be or shall constitute a waiver of any other term or provision hereof (whether or not similar), nor shall such waiver constitute a continuing waiver. No failure of a Party hereto to insist upon strict compliance by another Party hereto with any obligation, covenant, agreement, or condition contained in this Agreement shall operate as a waiver of, or estoppel with respect to, any subsequent or other failure. Whenever this Agreement requires or permits consent by or on behalf of a Party hereto, such consent shall be given in a manner consistent with the requirements for a waiver of compliance as set forth in this Section 7.2.

7.3. Fees and Expenses. Each of the Parties hereto shall bear and pay all fees, costs, and expenses incurred by it or any of its Affiliates in connection with the origin, preparation, negotiation, execution, and delivery of this Agreement and the Assignment Agreements and the transactions contemplated hereby or thereby (whether or not such transactions are consummated), including, without limitation, any fees, expenses, or commissions of any of its representatives.

(b) This Agreement and/or any of the rights, interests, or obligations hereunder of Seller may be assigned and/or transferred by Seller only with

Seller may assign and/or transfer all of its rights hereunder to any successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of the business of Seller only with the prior written consent of Purchaser, which consent shall be withheld only if the successor in interest either is a direct competitor of Purchaser in the Field of Use or is engaged in pending or imminent litigation with Purchaser.

(c) Neither this Agreement nor any of the rights, interests, or obligations hereunder of Purchaser may be assigned and/or transferred by Purchaser without the prior written consent of Seller, which consent shall not be unreasonably withheld or delayed except that the Purchaser may, without the consent of the Seller, assign and/or transfer all of its rights hereunder to any successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of the business of the Purchaser.

(d) If one Party requires consent under Sections 7.5(b)-(c) of the other to assign and / or transfer rights, interests, or obligations hereunder, that Party will request in writing consent of the other Party, who must respond in writing within sixty (60) calendar days. Failure to respond to the request for consent within sixty (60) calendar days will be deemed consent.

(a) This Agreement and the legal relations among the Parties hereto shall be governed by and construed under the substantive laws of the United States of America and the State of Illinois, without regard to conflict of laws rules.

(b) Each Party to this Agreement hereby irrevocably submits to the exclusive jurisdiction of any state or federal court sitting or located in the State of Illinois in any Action arising out of or relating to this Agreement or the other Assignment Agreements.

7.7. Headings. The headings contained in this Agreement and the schedules hereto are for convenience of reference only and shall not constitute a part hereof or define, limit, or otherwise affect the meaning of any of the terms or provisions hereof.

7.8. Entire Agreement. Other than as set forth in this Section 7.8 or any other Assignment Agreements, this Agreement and the Assignment Agreements embody the entire agreement and understanding between the Parties hereto with respect to the subject matter hereof and supersede all prior agreements, commitments, arrangements, negotiations or understandings, whether oral or written, between the Parties hereto, their respective Affiliates or any of the representatives of any of them with respect thereto, except as specifically referenced. There are no agreements, covenants, or undertakings with respect to the subject matter of this Agreement and the Assignment Agreements other than those expressly set forth or referred to herein or therein and no representations or warranties of

any kind or nature whatsoever, express or implied, are made or shall be deemed to be made herein by the Parties hereto except those expressly made in this Agreement and the Assignment Agreements.

7.9. Severability. Each term and provision of this Agreement constitutes a separate and distinct undertaking, covenant, term, and/or provision hereof. In the event that any term or provision of this Agreement shall be determined by a court of competent jurisdiction to be unenforceable, invalid or illegal in any respect, such unenforceability, invalidity or illegality shall, to the fullest extent permitted by law, not affect any other term or provision hereof, but this Agreement shall be construed as if such unenforceable, invalid or illegal term or provision had never been contained herein. Moreover, if any term or provision of this Agreement shall for any reason be held by a court of competent jurisdiction to be excessively broad as to time, duration, activity, scope or subject, the Parties request that it be construed, by limiting and reducing it, so as to be enforceable to the fullest extent permitted under applicable law.

7.10. No Third Party Beneficiaries. Except as and to the extent otherwise provided herein, nothing in this Agreement is intended, nor shall anything herein be construed, to confer any rights, legal or equitable, in any Person other than the Parties hereto and their respective successors and permitted assigns.

7.11. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which, when taken together, shall constitute one and the same instrument.

IN WITNESS WHEREOF, the Parties have executed, or caused their duly authorized representatives to execute, this Asset Purchase Agreement as of the date first written above.
