                  2. Prior Advances. Stratosphere and Grand acknowledge and
agree that Grand has previously advanced an aggregate of $18,551,902 under the

have advanced an aggregate of $50,000,000 pursuant to the Guarantee, and

in full all obligations and liabilities of Grand under the Guarantee. In
accordance with the Guarantee, funds advanced by Grand pursuant to the Guarantee
will constitute loans to Stratosphere and will be evidenced by one or more
promissory notes bearing interest at the rate of 14-1/4% per annum, will mature
one year after the maturity of the Notes, and will be subordinated to the full
repayment in cash of all principal, premium (if any), interest and other
payments under the Notes.

                  4. Completion of Resort. Stratosphere represents and warrants
that upon payment by Grand in Section 3 hereof, sufficient funds will be

Resort to become Operating (as defined in the Indenture) on or before September
30, 1996 and (b) all Amounts Required For Completion (as defined in the
Guarantee) payable by the Obligors on or prior to the date on which the Resort
becomes Operating. On or before September 30, 1996, Stratosphere shall take all
actions necessary to ensure that the Resort is Operating (as defined in the
Indenture) by that date.

                  5. Miscellaneous. (a) This Agreement shall be governed by and
construed in accordance with the laws of the State of Nevada, including the
Gaming Control Act and the regulations promulgated thereunder, without giving
effect to the principles of conflict of laws thereof.

                           (b) No provision of this Agreement or right granted
hereunder may be amended or waived in whole or in part, except by a writing duly
executed by authorized officers of each of Stratosphere and Grand, and no other
consents or approvals (of any additional beneficiaries or otherwise) shall be
required.

                           (c) This Agreement is intended only for the benefit
of Stratosphere and Grand and is not intended to benefit any other third party,
including the Trustee, the Holders or any other creditor of Stratosphere.

                           (d) Should any term, covenant, condition or provision
of this Agreement be determined to be invalid or unenforceable, it is the intent
of the parties that all other terms, covenants, conditions and provisions hereof
shall nonetheless remain in full force and effect.


                  IN WITNESS WHEREOF, the parties hereto have executed this
Funding Agreement as of the date first above written.
