ARTICLE IX

MISCELLANEOUS

Section 9.1 Injunctive Relief. Each party hereto acknowledges that it would be impossible to determine the amount of damages that would result from any breach of any of the provisions of this Agreement and that the remedy at law for any breach, or threatened breach, of any of such provisions would likely be inadequate and, accordingly, agrees that the other party shall, in addition to any other rights or remedies which it may have, be entitled to such equitable and injunctive relief as may be available from any court of competent jurisdiction to compel specific performance of, or restrain any party from violating, any of such provisions. In connection with any action or proceeding for injunctive relief, each party hereto hereby waives the claim or defense that a remedy at law alone is adequate and agrees, to the maximum extent permitted by Law, to have each provision of this Agreement specifically enforced against it, without the necessity of posting bond or other security against it, and consents to the entry of injunctive relief against it enjoining or restraining any breach or threatened breach of such provisions of this Agreement.

Section 9.2 Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors, heirs, legal representatives and permitted assigns. Neither party may directly or indirectly assign any of its rights or delegate any of its obligations under this Agreement, by operation of law or otherwise, without the prior written consent of the other party other than, for the avoidance of doubt, to any successor to DT in connection with a change in control of DT. Any purported direct or indirect assignment in violation of this Section 9.2 shall be null and void ab initio.

Section 9.3 Amendments; Waiver. No amendment, modification or discharge of this Agreement, and no waiver hereunder, and no extension of time for the performance of any of the obligations hereunder, shall be valid or binding unless set forth in writing and duly executed by (a) the Company where enforcement of the amendment, modification, discharge, waiver or extension is sought against the Company or (b) DT where enforcement of the amendment, modification, discharge, waiver or extension is sought against DT. Any such waiver shall constitute a waiver only with respect to the specific matter described in such writing and shall in no way impair the rights of the party granting such waiver in any other respect or at any other time. The waiver by the Company or DT of a breach of, or a default under, any of the provisions hereof, or to exercise any right or privilege hereunder, shall not be construed as a waiver of any other breach or default of a similar nature, or as a waiver of any of such provisions, rights or privileges hereunder. Except as expressly provided in this Agreement, the rights and remedies herein provided are cumulative and none is exclusive of any other, or of any rights or remedies that any party may otherwise have at law or in equity.

Section 9.4 Termination. This Agreement shall terminate at any time after which all DT Notes have been repaid in full; provided, however, that the provisions of this Article IX shall survive any termination of this Agreement or any provision hereof. Nothing in this Agreement shall be deemed to release any party from any liability for any willful and material breach of this Agreement occurring prior to any termination hereof or to impair the right of a party to compel specific performance by the other party of its obligations under this Agreement.

Section 9.5 Notices. Any notice, request, instruction or other document to be given hereunder by any party to the others shall be in writing and delivered personally or sent by registered or certified mail, return receipt requested and postage prepaid, or by facsimile (providing confirmation of such facsimile transmission):
