INDEMNIFICATION. The Sprint Parties and the Alamosa Parties will indemnify, hold harmless and defend each other against all claims, demands, judgments, causes of action, losses, costs, damages, penalties, fines, taxes, expenses or liabilities, including reasonable attorneys' fees and costs of defense, brought against or incurred by them, arising from or in connection with an attempt by or on behalf of any third party to enforce or collect an amount based on a Claim or Specific Claim. 11. EXPENSES. The Parties will pay their own expenses and attorneys' fees incurred in connection with the negotiation and execution of this Agreement. 12. ADDITIONAL FACTS. The Parties are aware that they may after the date of this Agreement discover claims or facts in addition to or different from those they now know or believe to be true with respect to Claims and Specific Claims. Nevertheless, it is the intention of the Parties to fully, finally and forever settle and release all such claims, including claims for damages and losses that are presently unknown or unanticipated, other than Business Activity Amounts that accrue before the Effective Date and that are not Specific Claims. In furtherance of this intention, the releases given in this Agreement are and will remain in effect as full and complete mutual releases of Claims and Specific Claims, other than Business Activity Amounts that accrue before the Effective Date and that are not Specific Claims, notwithstanding the discovery or existence of any additional or different facts relative to them. Each Party assumes the risk of any mistake in executing this Agreement and furnishing the releases set forth in this Agreement. Without limiting the generality of the foregoing, each Party waives and relinquishes any right or benefit that such Party has or may have under any provision of statutory or non-statutory law that may provide that a release does not extend to claims that a person does not know or suspect to exist at the time of execution of the release that, if known, would or may have materially affected the decision to give the release. 13. WAIVERS. No waiver by a Party of any breach of or default under this Agreement will be deemed to be a waiver of any other breach or default of any kind or nature of this Agreement. No acceptance of payment or performance by a Party after any such breach or default will be deemed to be a waiver of any breach or default of this Agreement, whether or not such Party knows of such breach or default at the time it accepts such payment or performance. No failure or delay on the part of a Party to exercise any right it may have will prevent the exercise of that right by that Party at any time the other Party continues to be in default, and no such failure or delay will operate as a waiver of any default. 14.

(B) Each Party acknowledges and agrees that in the event of any breach of this Agreement, the non-breaching Party or Parties may be irreparably harmed and may not be made whole by monetary damages. Accordingly, the Parties, in addition to any other 5 remedy to which they may be entitled, will be entitled to seek injunctive or other equitable relief in any court of competent jurisdiction to the extent permitted by applicable law. (C) Each Party waives, to the fullest extent permitted by law, the right to trial by jury in any legal proceeding arising out of or relating to the enforcement of this Agreement. (D) Each breaching Party agrees to reimburse the non-breaching Parties that prevails in the enforcement of this Agreement for the costs and expenses, including attorneys' fees, incurred by the non-breaching Parties. 15. ASSIGNMENT.

LIMITATION ON RIGHTS OF OTHERS. Nothing in this Agreement, whether express or implied, will be construed to give any person other than the Parties any legal or equitable right, remedy or claim under or in respect of this Agreement. 17.

(B) JURISDICTION. (i) Each Party irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any Kansas state court located in the County of Johnson or any Federal court of the United States of America located in the District of Kansas, and any appellate court from any such court, in any suit action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment.

Each Party irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such suit, action or proceeding in any such court and further waives the right to object, with respect to such suit, action or proceeding, that such court does not have jurisdiction over such party. (C) ENTIRE AGREEMENT; BINDING EFFECT.

The Parties participated in the negotiation and drafting of this Agreement.

If any term or provision of this Agreement or the Addenda is illegal, invalid or unenforceable for any reason whatsoever, that term or provision will be enforced to the maximum extent permissible so as to effect the intent of the Parties, and such illegality, invalidity or unenforceability will not affect the validity, legality or enforceability of the remainder of this Agreement or Addenda.
