("Pledgor"), to and for the benefit of CITICORP USA, INC., a Delaware corporation (which, together with its successors, assigns, endorsees, transferees and assignees, is hereinafter referred to as "Lender"). RECITALS A. Lender has made a loan (the "Loan") to Greenwood Plaza Partners, LLC ("Borrower") in the amount of $29,000,000 (the "Loan"), which Loan is evidenced by Borrower's Promissory Note of even date herewith in the amount of $29,000,000 payable to Lender (the "Note").

E. Pledgor's execution of this Agreement and pledging and assigning the Accounts to Lender is a condition precedent to Lender making the Loan to Borrower. Lender would not make the Loan to Borrower unless Pledgor entered into this Agreement 5 and pledged and assigned the Accounts to Lender. Pledgor acknowledges receipt of adequate consideration for entering into this Agreement and pledging the Accounts. AGREEMENT IN CONSIDERATION of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Pledgor agrees with Lender as follows: 1.

Security for Obligations. This Agreement secures the payment of all obligations of Borrower to Lender now or hereafter existing under the Note and all other Loan Documents, including any extensions, replacements, modifications, substitutions, amendments and renewals thereof, whether for principal, interest, fees, expenses or otherwise (all such obligations being the "Obligations").

(c) Pledgor will not create, assume or suffer to exist any lien on the Collateral other than pursuant to this Agreement.

(e) The pledge of the Collateral pursuant to this Agreement is made for the purpose of inducing Lender to make the Loan to Borrower, which Lender would not make without such pledge, and the proceeds of such Loan will be used to repay the outstanding loan from Pledgor to Borrower. (f) Pledgor has full power to enter into and perform its obligations under this Agreement and all other documents contemplated hereby or executed pursuant hereto. The execution and delivery of this Agreement and all other documents contemplated hereby or executed pursuant hereto and the performance and observance of their terms, conditions and obligations have been duly authorized by all necessary action on the part of Pledgor. This Agreement and all other documents contemplated hereby or executed pursuant hereto constitute or will constitute when executed and delivered by Pledgor, valid and binding obligations of Pledgor enforceable in accordance with their terms. (g) The execution and delivery of this Agreement and all other documents contemplated hereby or executed pursuant hereto and the consummation of all transactions contemplated hereby and thereby, do not and will not conflict with, or be in contravention of, any of Pledgor's governing documents, any law, order, rule or regulation applicable to Pledgor or any agreement or instrument to which Pledgor is a party or by which the Property is bound or affected, and will not result in the creation of any lien, charge or encumbrance of any nature upon the Property other than that contemplated hereby. 4. Covenants/Further Assurances. Pledgor agrees that, at any time and from time to time, at the expense of Pledgor, Pledgor will promptly execute and deliver all further instruments and documents and take all further action that may be necessary or desirable, or that Lender may request, in order to perfect and protect the assignment and security interest granted or purported to be granted hereby or to enable Lender to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, Pledgor will execute and file such financing or continuation statements, or amendments thereto, and such other assignments, instruments or notices, as may be necessary or desirable, or as Lender may request, in order to perfect and preserve the assignment and security interest granted or purported to be granted hereby. 4 8 5. Waiver/Withdraw of Collateral. (a) Pledgor waives any right to require Lender to proceed against any other person, including Borrower or any Guarantor, or to apply any other collateral or security which Lender may hold at any time for the account of the Borrower or Pledgor, or to exercise any other remedy. Without limiting the generality of the foregoing, the Pledgor specifically waives demand, protest, notice of protest, notice of default or dishonor (other than as specifically provided for in Section 6 below), notice of payment and non-payment, notice of default and non-payment at maturity (other than as specifically provided for in Section 6 below) and agrees that the Obligations and the rights of the Lender pursuant to this Agreement shall not be waived or modified in any respect by any release, substitution, or addition of collateral, security, guarantors, or endorsers with respect to the Obligations. (b) Pledgor acknowledges and agrees that, except as specifically set forth in the Loan Agreement with respect to certain releases of the Collateral under the conditions set forth therein, Pledgor has no right to and hereby relinquishes any right to withdraw or remove or have access to or the use of the Collateral or any funds in the Accounts. 6. Events of Default. The occurrence of any one or more of the following events or existence of any one or more of the following conditions shall constitute an Event of Default under this Agreement and all other Loan Documents: (a) Borrower shall fail to pay, when due, the principal of or interest on the Note, or any installment thereof (whether due on the date provided for herein or by acceleration or otherwise). (b) Pledgor shall fail to observe or perform any term, condition or covenant of this Agreement, and such failure shall not be cured within 10 days after notice from Lender. (c) Any material representation or warranty made by Pledgor herein or in connection with the making of the Loan or in any certificate, statement or report made pursuant to this Agreement is false, misleading or erroneous in any material respect. (d) There shall occur a default, or the occurrence of any event or circumstance defined as an Event of Default, under any of the Loan Documents other than this Agreement. 5 9 7. Remedies. Upon the occurrence and during the continuance of an Event of Default hereunder or an event which, with the giving of notice or the lapse of time, or both, would become an Event of Default hereunder: (a) Pledgor hereby irrevocably constitutes and appoints Lender its respective true and lawful attorney, with full power of substitution: to demand, collect, and receive payment of any and all monies or proceeds due or to become due under the Collateral; to execute any and all instruments required for the withdrawal or repayment of same, or any part thereof; and to complete such instruments in any respect; and in all respects to deal with the Collateral as the holder thereof; and, in its discretion, file any claim or take any other action or proceeding, either in its own name or in the name of the Pledgor which Lender may deem necessary or appropriate to protect and preserve the right, title, assignment, pledge, transfer, and interest of Lender hereunder. (b) All payments received by Pledgor under or in connection with the Collateral shall be received in trust for the benefit of Lender, shall be segregated from other funds of Pledgor and shall be forthwith paid over to Lender in the same form as so received (with any necessary endorsement), to the extent of the Obligations then due. (c) All payments made under or in connection with the Collateral and received by Lender may, in the discretion of Lender, be held by Lender as collateral for, and/or then or at any time thereafter applied in whole or in part by Lender against, all or any part of the Obligations in such order as Lender shall elect. Any surplus of such payments held by Lender and remaining after payment in full of all the Obligations shall be paid over to Pledgor or to whomsoever may be lawfully entitled to receive such surplus. (d) Take possession of the Collateral and apply all or any part of the Collateral to repay the Loan and satisfy Borrower's Obligations in such order as Lender may elect, irrespective of whether there is any breach or default under the Master Lease. Pledgor acknowledges that such a breach or default is not a condition to application of the Collateral by Lender to repay the Loan because the pledge of the Collateral is absolute and unrelated to the Master Lease. (e) Lender may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the Uniform Commercial Code (the "Code"). 8. Indemnity. Pledgor agrees to indemnify Lender from and against any and all claims, losses and liabilities growing out of or resulting from this Agreement (including, 6 10 without limitation, enforcement of this Agreement), except claims, losses or liabilities resulting from Lender's gross negligence or willful misconduct. 9. Security Interest Absolute. All rights of Lender and the assignment and security interest hereunder, and all obligations of Pledgor hereunder, shall be absolute and unconditional, irrespective of: (a) any lack of validity or enforceability of the Loan Documents; (b) any change in the time, manner or place of payment of, or in any other term of; all or any of the Obligations or any other amendment or waiver of or any consent to any departure from the Loan Documents; (c) any amendment, modification or restatement of the Loan Documents; (d) any exchange, release or nonperfection of any other collateral, or any release or amendment or waiver of or consent to departure from any guaranty, for all or any of the Obligations; (e) the existence of any claim, setoff, defense or other right that Borrower or Pledgor may have at any time against Lender or any other person, whether in connection with this Agreement or the Loan Documents; or (f) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, which might otherwise constitute a defense available to, or a discharge of, Pledgor or a third-party grantor of a security interest. 10. Amendments, Etc. No amendment or waiver of any provision of this Agreement nor consent to any departure by Pledgor herefrom, shall in any event be effective unless the same shall be in writing and signed by Lender, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which give. 11. Notices. Any notice required to be given to any party pursuant to any provision of this Agreement shall be given in the manner prescribed in the Loan Agreement. 12. Continuing Security Interest; Transfer of Note; Release of Collateral. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the payment in full of the Obligations (except that if Lender enters into a written agreement to voluntarily extend the Loan without Pledgor's consent, then this Agreement and Lender's security interest in the Collateral shall terminate), 7 11 (b) be binding upon Pledgor, its successors and assigns and (c) inure, together with the rights and remedies of Lender hereunder, to the benefit of Lender, its successors, transferees and assigns.

GLORIOSO ---------------------------------- Title: VICE PRESIDENT --------------------------------- 19 GENERAL HYPOTHECATION AGREEMENT CITICORP USA, INC. Not for Consumer Transactions In consideration of any liability of Greenwood Plaza Partners, LLC to Citicorp USA, Inc. (the "Lender") and/or in order to induce the Lender, acting in its discretion, to make loans or otherwise to extend or continue credit at any time(s) to Greenwood Plaza Partners, LLC, the undersigned hereby agree(s): I. That, as security for that certain Loan from Lender to Greenwood Plaza Partners, LLC in the amount of $29,000,000, as evidenced by that certain Loan Agreement of even date herewith (the "Loan Agreement") and all obligations in connection therewith (the "Obligations"), the undersigned hereby pledges and grants to the Lender a lien upon, a security interest in and an assignment of any and all property (as defined below) in which the undersigned at any time has rights and which at any time has been delivered, transferred, pledged, mortgaged or assigned to, or deposited in or credited to (a) the Permanant Cash Collateral Account (as defined in the Loan Agreement), or any other account in which the Permanent Cash Collateral (as defined in the Loan Agreement) is held, or (b) Account No. 554797 in the name of the undersigned maintained by Citibank, N.A. (the "Securities Intermediary") and all assets on deposit therein, (collectively, the "Pledged Account") and that is otherwise at any time in the possession or under the control or recorded on the books of or has been transferred to the Lender, the Securities Intermediary or any other third party(ies) acting in its behalf or designated by it to the extent identified with or intended for deposit in the Pledged Account. Stock dividends and the distributions on account of any stock or other securities subject to the terms and provisions hereof shall be deemed an increment thereto and if not received directly by the Lender shall be delivered immediately to it by the undersigned in form for transfer. II. That the Lender shall exercise reasonable care in the custody of any property at any time(s) in its possession or control hereunder, or otherwise subject to the terms and provisions hereof, but shall be deemed to have exercised reasonable care if such property is accorded treatment substantially equal to that which the Lender accords its own property (it being understood that the Lender shall have no responsibility for ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any property and whether or not the Lender has or is deemed to have knowledge of such matters), or if the Lender takes such action with respect to the property as the undersigned shall reasonably request in writing and to which the Lender consents, but no failure to comply with any such request nor any omission to do any such act requested by the undersigned shall be deemed a failure to exercise reasonable care, nor shall any failure of the Lender to take necessary steps to preserve rights against any parties with respect to any property in its possession or control, or otherwise subject to the terms and provisions hereof, be deemed a failure to exercise reasonable care. III. That, in addition to its rights and interests as herein set forth, the Lender may, as its option at any time after the occurrence of an Event of Default under the Loan Agreement and with or without notice to the undersigned, appropriate and apply to the payment or reduction, either in whole or in part of the amount owing on any one or more of the Obligations, then due, any and all moneys now or hereafter with the Lender, any affiliate of the Lender or any third party acting in its behalf or designated by it, on deposit or otherwise to the credit of or belonging to the undersigned in the Pledged Account. The undersigned understands and agrees that the Lender shall not be obligated to assert or enforce any rights, liens or security 20 interests hereunder or to take any action in reference thereto, and that the Lender may in its discretion at any time(s) relinquish its rights as to particular property or in any instance without thereby affecting or invalidating its rights hereunder as to any other property hereinbefore referred to or in any similar or other circumstance. IV. That, so long as any of the Obligations shall remain unpaid, the undersigned will not, unless the Lender shall otherwise consent in writing, create or suffer to exist any lien, security interest or other charge or encumbrance, or any other type of preferential arrangement, upon or with respect to the Pledged Account. V. That, so long as any of the Obligations shall remain unpaid the undersigned will maintain at all times in the Pledged Account assets acceptable to the Lender, consisting of cash and cash equivalents. Such cash and cash equivalents, and any additional securities, cash and cash equivalents pledged to the Lender from time to time and deposited in the Pledged Account, together with any income and distributions in connection with the securities (including stock splits) and any proceeds thereof deposited in the Pledged Account, shall be the "Pledged Collateral", provided that the Pledged Collateral specifically excludes Pledger's Account No. 554796 and any amounts on deposit therein. VI. That, so long as any of the Obligations shall remain unpaid, the undersigned may not withdraw any Pledged Collateral from the Pledged Account. VII. That each type of Pledged Collateral shall at all times be cash or cash equivalents as determined by Lender in Lender's sole and absolute discretion. VIII. That the undersigned shall comply with the following minimum collateral value requirements: (a) If at any time the loanable value of the Pledged Collateral as reasonably determined by Lender is less than $5,000,000, the undersigned shall deposit additional Pledged Collateral into the Pledged Account, as specified by the Lender in its sole discretion, so that, after giving effect to such deposit or repayment, the loanable value of the Pledged Collateral as reasonably determined by Lender is at least $5,000,000, or such lower amount as may be approved by Lender. The loanable value of any collateral shall be determined by Lender at the time that the collateral is included as part of the Pledged Collateral. The loanable value of cash and cash equivalence acceptable to Lender (e.g., short term U.S. Government Treasuries) shall generally be 100% of the market value. The loanable value of other types of Pledged Collateral may be less than 100% of the fair market value and such loanable value shall be determined by Lender in its sole discretion. IX. That in the event of the happening of any one or more of the following, any one of which shall constitute an event of default, to wit: (a) the non-payment of any of the Obligations when payable, or, in the case of Obligations payable on demand, when payment is demanded; (b) the failure of the undersigned forthwith to furnish additional collateral to the satisfaction of the Lender to the extent required hereunder, or to perform or observe any other covenant or obligation hereunder, or under any instrument, agreement or other document delivered in connection herewith; (c) any representation or warranty made by the undersigned under or in connection herewith shall have been incorrect when made or deemed made; (d) the insolvency, death, failure in or suspension of business, termination of current 2 21 employment, dissolution or termination of existence of the undersigned or any guarantor or endorser of any of the Obligations, except as otherwise permitted by the Loan Agreement; (e) the filing of a petition in bankruptcy by or against the undersigned or any such guarantor or endorser, or the commencement of any proceedings in bankruptcy, or under any Acts of Congress relating to the relief of debtors, for the relief or readjustment of any indebtedness of the undersigned or any such guarantor or endorser, either through the commencement of voluntary liquidation, reorganization, composition, extension or otherwise, or the taking of any action by the undersigned or any such guarantor or endorser authorizing any of the foregoing; (f) the making of an assignment for the benefit of creditors or the taking advantage of any insolvency law by the undersigned or any such guarantor or endorser; (g) the appointment of a receiver, conservator, liquidator, or similar officer for, or for any property of, the undersigned or any such guarantor or endorser; (h) the occurrence of a default or event of default under the Loan Agreement; (i) the attachment of or restraint as to any Pledged Collateral -- then, or at any time after the happening of any such event of default, any or all of the Obligations then existing, although otherwise unmatured or contingent, shall at the option of the Lender, become due and payable forthwith, without demand upon or notice to the undersigned; provided, however, that in the event of any actual or deemed entry of an order for relief with respect to the undersigned, under the Federal Bankruptcy Code, any or all of the Obligations then existing, although otherwise unmatured or contingent, shall automatically become and be due and payable. Furthermore, upon the occurrence of any such event of default the Lender shall have all of the rights and remedies provided to a secured party by the Uniform Commercial Code in effect in New York State and Colorado State at that time and the undersigned further agrees that (1) in the event that notice is necessary, written notice mailed to the undersigned at the address given below three business days prior to the date of public sale of property subject to the security interest of the Lender or prior to the date after which private sale or any other disposition of said property will be made shall constitute reasonable notice, but notice given in any other reasonable manner or at any other reasonable time shall be sufficient; (2) without precluding any other methods of sale, the sale of property shall have been made in a commercially reasonable manner if conducted in conformity with reasonable commercial practices of banks disposing of similar property, but in any event, the Lender may sell at its option on such terms as it may choose without assuming any credit risk and without obligation to advertise; and (3) the Lender may require the undersigned to assemble the property subject to the security interest of the Lender and to make such property available to the Lender at a time and place designated by the Lender, all at the expense of the undersigned. Upon the occurrence of an event of default, if the fair market value of the Pledged Collateral exceeds $5,000,000, the maximum amount Lender shall be entitled to hereunder shall be Pledged Collateral with a fair market value of $5,000,000 (on the date that Lender exercises its rights with respect to such collateral). X. That all rights of the Lender and liens of the Lender shall continue unimpaired, and that the undersigned shall be and remain bound by the Obligations in accordance with the terms thereof, notwithstanding the release of any of the aforementioned property, or of any rights or interests therein, or any delay, extension of time, renewal, compromise or other indulgence granted by the Lender in reference to any of the Obligations or any promissory note, draft, bill of exchange or other instrument or other obligations given in connection therewith or constituting a part of the said property, the undersigned hereby waiving all notice of any such delay, extension, release, substitution, renewal, compromise or other indulgence, and hereby consenting to be bound thereby as fully and effectually as if the undersigned had expressly agreed thereto in advance. XI. That the Lender may, at its option and without obligation to do so, at any time after an event of default transfer to or register in the name of its nominee(s), including any "clearing corporation" 3 22 or "custodian bank" as defined in the Uniform Commercial Code in effect in the state of New York or Colorado and any nominee(s) thereof, all or any part of the aforementioned property and it may do so before or after the maturity of any of the Obligations and with or without notice to the undersigned. XII. That the Lender may assign or otherwise transfer all or any of the Obligations, and may deliver all or any of the property to the transferee(s), who shall thereupon become vested with all the powers and rights in respect thereof given to the Lender herein or otherwise and the Lender shall thereafter be forever relieved and fully discharged from any liability or responsibility with respect thereto, all without prejudice to the retention by the Lender of all rights and powers not so transferred. Furthermore that the Lender may, in connection with any such assignment, transfer or delivery, disclose to the assignee or transferee or proposed assignee or proposed transferee any information relating to the undersigned furnished to the Lender by or on behalf of the undersigned, provided, that, prior to any such disclosure, the assignee or transferee or proposed assignee or proposed transferee shall agree to preserve the confidentiality of any confidential information related to the undersigned received by it from the Lender. XIII. That, if this agreement is executed by two or more parties, they shall be severally bound and committed hereunder, and the term "undersigned" wherever used herein shall be construed to refer to each of such parties separately, all in the same manner and with the same effect as if each of them had signed separate instruments. If any party hereto is a partnership, the agreements herein contained shall remain in force and applicable notwithstanding changes in the individuals comprising the partnership, and the term "undersigned" shall include any altered or successor partnerships, but the predecessor partnerships and their partners shall not thereby be released from any liability. XIV. That the Lender is authorized, at its option, to file Financing Statement(s), Amendments and Continuation Statement(s) without the signature of the undersigned with respect to any of the aforementioned property; XV. That, the Lender is irrevocably appointed the attorney-in-fact of the undersigned with full authority in the place and stead of the undersigned and in the name of the undersigned, in the Lender's name or otherwise, from time to time in the Lender's discretion, to take any action and to execute any instrument, document or agreement (including, without limitation, financing statements, amendments thereto and continuation statements) which the Lender may deem necessary or advisable to accomplish the purposes of this agreement including, without limitation, to perfect, preserve, and protect the security interest granted or purported to be granted hereunder.
