(d)                                 Construction.  The Parties have participated jointly in the negotiation and drafting of this Agreement.  In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement.

(e)                                  Headings; Construction.  The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.  All words used in this Agreement will be construed to be of such gender or number as the circumstances require.  Unless otherwise expressly provided, the word “including” does not limit the preceding words or terms.

(f)                                   Severability.  If any term or other provision of this Agreement is determined to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party.  Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties hereto as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

(g)                                 Entire Agreement and Modification.  This Agreement (together with the Exhibits and schedules) constitutes the entire agreement of the Parties and supersedes all prior agreements and undertakings, both written and oral, between the Parties hereto with respect to the subject matter hereof.  This Agreement may not be amended except by a written agreement executed by the Party to be charged with the amendment.

(h)                                 Assignment.  This Agreement shall not be assigned by operation of law or otherwise.

(i)                                    Parties in Interest.  This Agreement shall be binding upon and inure solely to the benefit of each Party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

15

(j)            Waiver; Remedies Cumulative.  No failure or delay on the part of any Party hereto in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof or of any other right.  To the maximum extent permitted by applicable law, (i) no claim or right arising out of this Agreement or the documents referred to in this Agreement can be discharged by one Party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other Party; (ii) no waiver that may be given by a Party will be applicable except in the specific instance for which it is given; and (iii) no notice to or demand on one Party will be deemed to be a waiver of any obligation of such Party or of the right of the Party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.  All rights and remedies existing under this Agreement are in addition to, and not exclusive of, any rights or remedies otherwise available.

(k)           Further Assurances.  The Parties hereto agree (i) to furnish upon request to each other such further information, (ii) to execute and deliver to each other such other documents, and (iii) to do such other acts and things, all as another Party hereto may reasonably request for the purpose of carrying out the intent of this Agreement and the documents referred to in this Agreement.

(l)            Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAW.

(n)           Counterparts.  This Agreement may be executed in one or more counterparts, and by the different Parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.  The Parties further agree that facsimile signatures or signatures scanned into .pdf (or similar) format and sent by e-mail shall be deemed original signatures.

16

(o)           Damages.  The Parties agree and acknowledge that money damages may not be an adequate remedy for any breach of the provisions of this Agreement; therefore, in the event of a breach by either party of any of the provisions of this Agreement, the other party or its successors or assigns may, in addition to other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violations of the provisions hereof.
