                SECTION 1.01 DEFINITIONS. All capitalized terms used in this
Agreement which are not otherwise defined herein shall have the respective
meanings set forth in Appendix A hereto (the "Definitions Appendix"), and the
rules of construction and usage set forth in the Definitions Appendix shall be
applicable herein and therein. The Definitions Appendix is incorporated herein
by reference in its entirety and is a part of this Agreement to the same extent
as if it had been set forth in this Section 1.01 in full. Capitalized terms used
but not defined in this Agreement shall have the meanings set forth in the
Venture Agreement.

                                   ARTICLE II
                                    THE LOAN

                SECTION 2.01 THE LOAN. Lender agrees, on the terms and
conditions set forth in this Agreement, to make a loan on a revolving basis (the
"Loan") to the Borrower in the maximum amount outstanding at any one time of
Twenty Million Dollars and 00/100 ($20,000,000.00), in order to provide Borrower
with funds that it will contribute to its indirect Subsidiaries, to be used by
such Subsidiaries in the development of the Projects. Sums borrowed and repaid
may be readvanced upon compliance with the terms and conditions of this
Agreement.

                SECTION 2.02 FUNDING OF LOAN. Subject to the terms and
conditions set forth in this Agreement, Lender shall make advances of the Loan
to Borrower in immediately available funds within five (5) days after Lender's
receipt of a requisition for a loan advance complying with this Agreement;
provided, however, that Lender shall not be obligated to make more than two (2)
advances per month. Unless the Lender determines that any applicable condition
specified in Article III has not been satisfied, the Lender shall make the funds
available to the Borrower at the Lender's address as set forth on the signature
page to this Agreement.

                SECTION 2.03 USE OF LOAN PROCEEDS. All Loan proceeds made
available to Borrower by Lender in accordance with this Agreement shall be made
available by Borrower to its Subsidiaries to fund costs associated with the
development of the Projects, as identified on Exhibit B attached hereto. Each
loan advance requisition delivered by Borrower to Lender shall identify the
Project for which the advance is being requested.


<PAGE>

                SECTION 2.04 NOTE: EVIDENCE OF LOAN. The Loan shall be evidenced
by a single, non-negotiable promissory note payable to Lender in an amount equal
to the Loan, in the form of the Note.

                SECTION 2.05 INTEREST RATE. Interest shall accrue on the
outstanding principal amount of the Loan at the rate of ten percent (10%) per
annum.

                SECTION 2.06 MATURITY OF LOAN. The principal amount of the Loan
together with accrued interest shall be due and payable on the Termination Date.

                SECTION 2.07 LOAN REPAYMENT. The principal amount of the Loan,
together with any accrued interest, shall be repaid from the proceeds of the
construction loans for the Projects. To the extent that any existing Loan
balance exists with respect to a Project for costs for which the Borrower
receives construction loan proceeds, to the extent permitted by any lender, such
construction loan proceeds shall be applied to that portion of the Loan balance
advanced, incurred, or accrued in connection with such costs. In addition,
Borrower may, upon at least three (3) Business Days notice to the Lender, repay
the Loan, in whole, or in part in any amount, by paying the principal amount to
be repaid together with accrued interest thereon to the date of repayment.

                SECTION 2.08 GENERAL PROVISIONS AS TO PAYMENTS. Notwithstanding
any Loan repayment Borrower may undertake or which may be required under Section
2.07 above, Borrower shall also make monthly payments of interest only on the
Loan not later than 12:00 Noon, prevailing U.S. Eastern Standard Time, on the
first (1st) day of each month, without set-off, counterclaim or other deduction,
in U.S. Dollars or other funds immediately available to the Lender at its
address. Whenever the payment of principal of, or interest on, the Loan shall be
due on a day which is not a Business Day, the date for payment thereof shall be
extended to the next succeeding Business Day unless such Business Day falls in
another calendar month, in which case the date for payment thereof shall be the
next preceding Business Day. If the date for payment of principal is extended by
operation of law or otherwise, interest thereon shall be payable for such
extended time.

                Notwithstanding the foregoing or any other provision of this
Agreement to the contrary, payments of interest shall be required to be made
only if and to the extent that Borrower has sufficient Gross Revenues or
Proceeds from Capital Transactions available to pay such interest in accordance
with the provisions of Sections 3.2(h), 5.3.1 and 5.3.2 of the Venture
Agreement; and payments of principal shall be required to be made only if and to
the extent that Borrower has sufficient Proceeds from Capital Transactions
available to pay such principal in accordance with the provisions of Sections
5.3.1 and 5.3.2 of the Venture Agreement. To the extent that such Gross Revenues
or Proceeds from Capital Transactions are insufficient to pay interest under the
Loan on a current basis, as set forth in this paragraph, any such interest shall
accrue.

caused by the act or omission of Lender or SALII, Borrower agrees to indemnify
the Lender, its Affiliates and the respective directors, officers, trustees,
agents and employees of the foregoing (each an "Indemnitee") and hold each
Indemnitee harmless from and against any and all liabilities, losses, damages,
costs and expenses of any kind, including, without limitation, the reasonable
fees and disbursements of counsel, which may be incurred by such Indemnitee in

                SECTION 7.05 SUCCESSORS AND ASSIGNS. The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, provided that neither Lender nor

to the nonexclusive jurisdiction of the United States District Court for the
Eastern District of Virginia and of any Virginia state court for purposes of all
legal proceedings arising out of or relating to this agreement or the
transactions contemplated hereby. Each of the parties hereto irrevocably waives,
to the fullest extent permitted by law, any objection which it may now or
hereafter have to the laying of the venue of any such proceeding brought in such
a court and any claim that any such proceeding brought in such a court has been
brought in an inconvenient forum.

                SECTION 7.07 COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument. This Agreement and the Note constitute the entire agreement
and understanding among the parties hereto and supersede any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective upon receipt by the Lender of
counterparts hereof signed by each of the parties hereto (or, in the case of any
party as to which an executed counterpart shall not have been received, receipt
