                        (a)   Administrator.  The arbitration of all Covered Claims will be administered by the American Arbitration Association, Inc., a New York not-for-profit corporation, together with its successors (the “Arbitration Administrator”).

                        (b)   Procedural Law.  Except as otherwise provided herein, the arbitration of all Covered Claims will be governed by Colorado procedural law (including the rules of civil procedure, evidence and court (excluding local rules)) as if the Covered Claims had been brought in a District Court of the State of Colorado; provided, however, that (i) the parties waive any right to jury, (ii) there shall be no appellate relief available, and (iii) discovery will be limited to matters which are directly relevant to the issues in the arbitration.

                        (c)   Arbitrator.  The arbitration shall be conducted by a single, neutral arbitrator (the “Arbitrator”) to be selected under this Section 11.3(c).  Within seven (7) business days from service of an arbitration complaint, the Company and Investors Representative will either agree upon an Arbitrator or, failing such agreement, shall exchange lists containing the names of five (5) candidates proposed by each of them to serve in such capacity.

                        (1)   If any proposed candidate shall be common to both lists, that individual shall serve as the Arbitrator (with the individual whose last name comes first alphabetically being chosen in case more than one individual is common to both lists).

If any individual selected in accordance with the procedures provided in this Section 11.3(c) is at any time, including after the selection of the Arbitrator, unable or unwilling to act as the Arbitrator, the individual whose ranking is next lowest shall be approached until an Arbitrator is selected.  If none of the candidates on the Combined List is capable or willing to serve as the Arbitrator, the Company and Investors Representative may either agree to repeat the process until an Arbitrator is selected or, at the election of either of them, proceed in accordance with the then prevailing rules of the Arbitration Administrator regarding arbitrator selection.

                        (d)   Emergency Relief.  Applications for emergency relief made prior to the appointment of the Arbitrator shall be made in accordance with the Arbitration Administrator’s Optional Rules for Emergency Measures of Protection.

                        (e)   Excluded Claims.  “Covered Claims”, as used in this Agreement, shall not include compulsory or permissive cross-claims between or among the parties that arise in a legal action brought by or against a non-signatory hereto (each, a “Non-Signatory Action”); provided, however, that a party that has the right to assert a permissive cross-claim against another party in a Non-Signatory Action may choose to treat that claim as a Covered Claim and assert it in accordance with the terms of this Section 11.3(e).

                        (f)   Record and Proceedings.  A full stenographic or electronic record of all proceedings in the arbitration shall be maintained, and the Arbitrator shall issue rulings, a statement of decisions and a judgment as if the Arbitrator were a sitting Judge of the District Court of the State of Colorado, with all of the powers (including with respect to remedies) vested in such a judge.

                        (g)   Res Judicata, Collateral Estoppel and Law of the Case.  A decision of the Arbitrator shall have the same force and effect with respect to collateral estoppel, res judicata and law of the case that such decision would have been entitled to if decided in a court of law, but in no event shall such a decision be used by or against a party to this Agreement in a Non-Signatory Action.

                        (h)   Jurisdiction; Venue; Enforcement of Award.  The parties hereto consent and submit to the exclusive personal jurisdiction and venue of the District Court and the Federal District Court, located in the County of Denver, State of Colorado, to compel arbitration of Covered Claims in accordance herewith, to enforce any arbitration award granted pursuant hereto, including any award granting equitable relief, and to otherwise enforce this Agreement and carry out the intentions of the parties to resolve all Covered Claims through arbitration.

                        (i)   Confidentiality.  All arbitration proceedings, including any appellate proceedings, will be closed to the public and confidential, and all records relating thereto will be permanently sealed, except as necessary to obtain court confirmation of the judgment of the Arbitrator and except as necessary to give effect to res judicata and collateral estoppel (such as in a dispute between the parties to such arbitration proceedings that is not a Covered Claim), in

-31-

which case all filings with any court shall be sealed to the extent permissible by the court.  A party (including such party’s counsel or other representatives) may disclose to the media only the fact and generic nature of a Covered Claim that is being, or has been, arbitrated pursuant hereto.  Nothing in this Section 11.3(i) is intended to, or shall, preclude a party from communicating with, or making disclosures to, its lawyers, tax advisors, auditors and insurers, as necessary and appropriate, or from making such other disclosures as may be required by law.

                        (j)   Fees and Costs.  The Company and Investors shall split equally the fees of the Arbitrator and the administrative costs of the arbitration.  All other costs associated with the arbitration, or any litigation to enforce any arbitration award granted pursuant hereto (including attorney’s fees and related costs), shall be borne by the parties incurring such costs and expenses.
