RECITALS A. Landlord is the owner or the ground lessee of the real property described on Exhibit A attached hereto (the "Property"). B. Pursuant to a certain Lease dated _____________________, _______________ (the "Lease"), Landlord has leased to Tenant all or a portion of the Property. C. Financing for the Property is to be provided by a loan to be made by Lender to Borrower (the "Loan"). The Loan will be secured, in part, by a Deed of Trust (the "Deed of Trust") from Landlord to the Public Trustee of Boulder County, Colorado, for the use and benefit of Lender. D. The parties wish to provide for subordination of the Lease to the Deed of Trust, for the continuation of Tenant's right to occupy the Property so long as no default exists under the Lease, notwithstanding any foreclosure of the Deed of Trust, and for Tenant's attornment to any person or entity who may acquire title to the Property upon or in lieu of foreclosure of the Deed of Trust. NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: TERMS AND CONDITIONS 1. Status of Lease. Tenant represents and warrants to Lender that the Lease has been duly authorized, executed and delivered by Tenant. Landlord and Tenant each represent and warrant to Lender that the Lease is in full force and effect and has not been modified or amended in any way, and neither party to the Lease is in default with respect to such party's obligations under the Lease as of the date of this Agreement. 2. Assignment of Landlord's Interest in Lease. Tenant acknowledges that, pursuant to the Deed of Trust, Landlord has assigned all of the rights and benefits (but none of the obligations) of Landlord under the Lease to Lender. Upon notice from Lender that Lender has revoked its revocable waiver of Lender's rights under the Deed of Trust, and until subsequent notice from Lender to the contrary, Tenant shall pay all rent and other sums coming due under the Lease directly to Lender or in accordance with Lender's instructions, notwithstanding any contrary instruction which Tenant may receive from Landlord. Landlord hereby expressly authorizes Tenant to make such payments directly to Lender and agrees that the rights of Tenant under the Lease will in no way be prejudiced or impaired by reason of Tenant's compliance with any such notice from Lender. 3. Subordination of Lease. Tenant hereby subordinates the Lease, and all of Tenant's right, title and interest in and to the Property, to the Deed of Trust and to any and all increases, renewals, Copyright (C) 1999 Flatiron Park Company modifications, extensions, substitutions, replacements and/or consolidations of the Deed of Trust. The lien of the Deed of Trust shall, with respect to all amounts now or at any time hereafter secured by such lien (including amounts in excess of the principal face amount of the Note referred to in the Deed of Trust) be senior and superior in all respects to any interest of Tenant in the Property. 4. Non-Disturbance. Lender agrees that so long as Tenant is not in default under the Lease and no right exists under the terms of the Lease whereby the owner of the Property is entitled to terminate the Lease, the Lease will not be terminated, and Tenant will not be disturbed in its possession of the Property, by or as a result of any foreclosure of the Deed of Trust or any conveyance in lieu of any such foreclosure. Nothing in this paragraph shall prevent Lender from giving any notice to Tenant required by law in connection with any such foreclosure, or joining Tenant as a party in any judicial foreclosure action, but no such notice and no such joinder shall have any effect inconsistent with the first sentence of this paragraph. 5. Attornment. Tenant shall attorn to, and recognize as Tenant's landlord under the Lease, Lender or any other person who may acquire title to the Property upon foreclosure of the Deed of Trust or by conveyance in lieu of such foreclosure. The provisions of this paragraph shall be self-executing and no further writing or other formal act of attornment shall be required, but Tenant shall, upon the request of any person so acquiring title to the Property, execute and deliver to such person an instrument in recordable form acknowledging such attornment, but not otherwise modifying or amending Tenant's obligations under the Lease. From and after any such attornment, Lender or any other person who may acquire title to the Property upon or in lieu of a foreclosure of the Deed of Trust shall be bound to Tenant under all of the terms, covenants and conditions of the Lease; provided, however, that Lender or such other person shall not be (a) liable for any act or omission of any prior landlord (including Landlord); (b) bound by Tenant's payment to any prior landlord (including Landlord) under the Lease of any rents beyond that due for the then-current rent period; (c) liable for the return or application of any security deposits unless Landlord delivers such deposits to Lender or such other person; (d) bound by any amendment or modification to the Lease made without Lender's written consent, which consent shall not be unreasonably withheld; or (e) subject to any offsets or deficiencies which Tenant might be entitled to assert against any prior landlord (including Landlord). 6. Notice and Cure Rights. Notwithstanding anything to the contrary in the Lease, Tenant agrees that it shall not commence any action against Landlord or otherwise pursue any right or remedy against Landlord in consequence of a default by Landlord under the terms and provisions of the Lease unless written notice of such default is given to Lender. Tenant further agrees that Lender shall have the right, but shall not be obligated, to cure such default on behalf of Landlord within thirty (30) days after receipt of such notice. Tenant further agrees not to invoke any of its remedies under the Lease (except in the case of emergency repairs) unless such default shall remain uncured at the expiration of the thirty (30) day period after such notice of default is given to Lender, or if such default cannot reasonably be cured within such thirty (30) day period, unless the cure of such default is not commenced within such thirty (30) day period and thereafter prosecuted diligently to completion. In addition to such notice and cure rights, Tenant agrees that if the Event of Default is one that Lender cannot reasonably cure, such Event of Default shall be considered excused. 7. Casualty. Notwithstanding anything to the contrary that may be contained in the Lease, Lender shall have the right, in its sole discretion, to apply any insurance proceeds received as a result of any casualty to the Property to reduce the mortgage or debt owed to Lender. 8. Responsibility. Neither this Agreement nor the Deed of Trust shall, prior to Lender's succession to Landlord's interest in the Property, through foreclosure, assignment in lieu of foreclosure, or a possessory action, operate to place responsibility for the control, care, management or repair of the Property upon Lender, or impose upon Lender any responsibility for the performance of the terms and conditions of the Lease.

Any party may change such party's address for future notices by notice to the other parties in accordance with this paragraph. 10. Real Covenants; Successors and Assigns.
