any agreement in respect of Pledged Equity or otherwise adversely affect or diminish any Pledged Equity.

(i) conflicts with:

(A) any domestic or foreign Law,

(C) any agreement, judgment, license, order or permit applicable to or binding upon Granter or any issuer of Pledged Equity, or

(c) If Granter fails to perform any agreement or obligation contained herein, the Secured Party may, but shall have no obligation to, itself perform, or cause performance of, such agreement or obligation, and the expenses of the Secured Party incurred in connection therewith shall be payable by Granter under Section 6.6.

(d) The Secured Party shall have the right, at any time upon the occurrence and during the continuance of an Event of Default and without notice to Granter, to transfer to or to register in the name of the Secured Party or any of its nominees any Pledged Equity, subject only to the revocable rights specified in Section 5.1.

(h) Apply by appropriate judicial proceedings for appointment of a receiver for the Collateral, or any part thereof, and Grantor consents to any such appointment.

(k) To the extent notice of sale shall be required by law with respect to Collateral, at least 10-days’ notice to Granter of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification; provided that, if the Secured Party fails in any respect to give such notice, its liability for such failure shall be limited to the liability (if any) imposed on it by law under the UCC. The Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

Section 6.3. Application of Proceeds. If an Event of Default shall have occurred and be continuing, any cash held by or on behalf of the Secured Party and all cash proceeds received by or on behalf of the Secured Party in respect of any sale of, collection from, or other realization upon any Collateral may, in the discretion of the Secured Party, be held by the Secured Party as collateral for, and/or then or at any time thereafter applied in whole or in part by the Secured Party for the benefit of the Beneficiaries against, any Secured Obligation, in the following manner:

(a) First, paid to the Secured Party for any amounts then owing to the Secured Party pursuant to the Credit Agreement or otherwise under the Loan Documents or that has otherwise been incurred by the Secured Party in connection with the payment or other satisfaction of any Lien, encumbrance or adverse claim upon or against any Collateral or any other action that the Secured Party determines is reasonably appropriate in connection with the preservation or maintenance of the Collateral.

(b) Second, paid to the Beneficiaries in payment of the Secured Obligations, ratably in accordance with the respective amounts thereof then owing to the Beneficiaries or as otherwise provided in the Credit Agreement.

(c) Third, any surplus of such cash or cash proceeds held by or on the behalf of the Secured Party and remaining after payment in full of all the Secured Obligations shall be paid over to Granter or to whatever Person may be lawfully entitled to receive such surplus.

Section 6.4. Deficiency. If the proceeds of any sale, collection or realization of or upon the Collateral of Granter by the Secured Party are insufficient to pay all Secured Obligations and all other amounts to which the Secured Party is entitled, Granter shall be liable for the deficiency, together with interest thereon as provided in the Loan Documents or (if no interest is so provided) at such other rate as shall be fixed by applicable law, together with the costs of collection and the reasonable fees of any attorneys employed by the Secured Party (that are not employees of the Secured Party or any Affiliate of the Secured Party) and/or the other Beneficiaries to collect such deficiency. Collateral may be sold at a loss to Granter, and the Secured Party shall have no liability or responsibility to Granter for such loss. Granter acknowledges that a private sale may result in less proceeds than a public sale.

Section 6.5. Private Sales of Pledged Equity. The Beneficiaries may deem it impracticable to effect a public sale of any Pledged Equity and may determine to make one or more private sales of such Pledged Equity to a restricted group of purchasers that will be

obligated to agree, among other things, to acquire the same for their own account, for investment and not with a view to the distribution or resale thereof. Any such private sale may be at a price and on other terms less favorable to the seller than the price and other terms that might have been obtained at a public sale. Any such private sale nevertheless shall be deemed to have been made in a commercially reasonable manner, and neither the Secured Party nor any other Beneficiary shall have any obligation to delay sale of any such Pledged Equity for the period of time necessary to permit their registration for public sale under the Securities Act. Any offer to sell any such Collateral that has been:

(i) publicly advertised on a bona-fide basis in a newspaper or other publication of general circulation in the financial community of Denver, Colorado (to the extent that such an offer may be so advertised without prior registration under the Securities Act), or

(ii) made privately in the manner described above to not less than 15 bona-fide offerees,

shall be deemed to involve a “public disposition” under Section 9-610(c) of the UCC, notwithstanding that such sale may not constitute a “public offering” under the Securities Act, and any Beneficiary may bid for such Collateral.

Section 6.6. Indemnity and Expenses. In addition to, but not in qualification or limitation of, any similar obligations under other Loan Documents:

(a) Grantor will indemnify the Secured Party, each other Beneficiary and any agent appointed pursuant to Section 6.9 from and against all claims, losses and liabilities growing out of or resulting from this Agreement (including enforcement of this Agreement), WHETHER OR NOT SUCH CLAIMS, LOSSES AND LIABILITIES ARE IN ANY WAY OR TO ANY EXTENT CAUSED BY OR ARISING OUT OF SUCH INDEMNIFIED PARTY’S OWN NEGLIGENCE OR STRICT LIABILITY, except to the extent such claims, losses or liabilities are proximately caused by such indemnified party’s individual gross negligence or willful misconduct.

(b) Grantor will upon demand pay to the Secured Party the amount of all costs and expenses, including the reasonable fees and disbursements of the Secured Party’s counsel (that are not employees of the Secured Party or any of its Affiliates) and of any experts and agents, that the Secured Party may incur in connection with:

(i) the transactions that give rise to this Agreement;

(ii) the preparation of this Agreement and the perfection and preservation of this security interest created under this Agreement; or

(iii) the administration of this Agreement.

(c) Grantor will upon demand pay to the Secured Party the amount of all costs and expenses, including the fees and disbursements of the Secured Party’s counsel (that are not

employees of the Secured Party or any of its Affiliates) and of any experts and agents, that the Secured Party may incur in connection with:

(i) the custody, preservation, use or operation of, or the sale of, collection from, or other realization upon, any Collateral;

(ii) the exercise or enforcement of any right of the Secured Party hereunder; or

(iii) the failure by Grantor to perform or observe any of the provisions hereof.

Section 6.7. Non-Judicial Remedies. In granting to the Secured Party the power to enforce its rights hereunder without prior judicial process or judicial hearing, to the extent permitted by applicable Law, Grantor waives, renounces and knowingly relinquishes any legal right that might otherwise require the Secured Party to enforce its rights by judicial process and confirms that such remedies are consistent with the usage of trade, are responsive to commercial necessity and are the result of a bargain at arm’s length. The Secured Party may, however, in its discretion, resort to judicial process.

Section 6.8. Limitation on Duty of the Secured Party in Respect of Collateral. Beyond the exercise of reasonable care in the custody thereof, the Secured Party shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or as to the preservation of rights against prior parties or any other rights pertaining thereto. The Secured Party shall be deemed to have exercised reasonable care in the custody of Collateral in its possession if such Collateral is accorded treatment substantially equal to which that it accords its own property, and the Secured Party shall not be liable or responsible for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of the act or omission of any warehouseman, carrier, forwarding agency, consignee or other agent or bailee selected by the Secured Party in good faith.

Section 6.9. Appointment of Other Agents. At any time, in order to comply with any legal requirement in any jurisdiction, the Secured Party may appoint any bank or trust company or one or more other Persons, either to act as co-agent or co-agents, jointly with the Secured Party, or to act as separate agent or agents on behalf of the Secured Party, with such power and authority as may be necessary for the effective operation of the provisions hereof and may be specified in the instrument of appointment.
