together with interest as set out herein at its offices in the District of
Columbia or such other place as Holder may designate in writing, or by wire
transfer to Holder's designated bank account.

     1. LOAN AGREEMENT. This Promissory Note (this "Note") has been issued under
the terms of a Loan Agreement (Unsecured) between the Maker and the Holder dated
the date hereof (collectively with all modifications, renewals, extensions and
replacements thereof and therefor, the "Agreement"). This Note evidences the
obligation of the Maker to repay a loan in the aggregate principal amount of Ten
Million Dollars ($10,000,000) made pursuant to the Agreement. The Holder is
entitled to the benefits of the Agreement and all of the exhibits thereto, and
reference is made thereto for a description of all rights and remedies
thereunder. Neither reference to the Agreement, nor any provision thereof shall
affect or impair the absolute and unconditional obligation of the Maker to pay,
when due, the principal amount hereof, together with all interest accrued
thereon. Capitalized terms not otherwise defined herein shall have the meanings
set forth in the Agreement.

     2. INTEREST RATE; PAYMENT; DEFAULT RATE.

        (a) ACCRUAL, PAYMENT AND DEFAULT RATES. Commencing on the date hereof
and continuing until payment of the indebtedness hereunder in full, interest
shall (subject to the immediately following sentence) accrue on the unpaid
balance hereof at the fixed rate of fifteen percent (15%) per annum (the
"Accrual Rate") and shall be payable semi-annually, in arrears, at the fixed
rate of ten percent (10%) per annum (the "Payment Rate") as set out in
subparagraph (b) below. The Accrual Rate shall increase to 18% per annum when
and if an Event of Default shall occur, and such rate shall remain in effect
until the relevant payment is made or such Event of Default is otherwise cured,
whereupon the Accrual Rate shall decline to the rate previously in effect.

        (b) PAYMENTS. On the fifteen (15th) day of each May and November of the
term hereof commencing May 15, 2001, payments of interest accrued at the
Interest Rate through the end of the immediately preceding six-month period (or
in the case of the payment due on May 15, 2001, through the end of the period
beginning at Closing and ending on May 14, 2001) shall be due and payable.

<Page>

        (c) DEFERRAL AND COMPOUNDING. On the fourteenth (14th) day of each May
and November of the term hereof, the then outstanding principal balance of this
Note shall be increased by an amount (the "PIK Amount") equal to the difference
between (i) interest accruing at the Accrual Rate on the principal balance of
this Note outstanding from time to time during the immediately preceding
six-month period (or in the case of such increase occurring on May 14, 2001,
during the period beginning at Closing and ending on May 14, 2001), and (ii)
interest calculated at the Payment Rate on the principal balance of this Note
outstanding from time to time during such six-month period (or in the case of
such increased occurring on May 14, 2001, during the period beginning at Closing
and ending on May 14, 2001). After the end of each such period, interest shall
be calculated on the then outstanding principal balance of this Note, as
increased by the PIK Amount for such period and decreased by any principal
repayments during such period, with the end result that unpaid interest under
this Note shall be compounded semi-annually.

        (d) OPTIONAL PAYMENT OF PIK AMOUNT. Maker may pay the PIK Amount for any
period in whole or in part at any time, either before or after it is added to
the principal balance hereof.

     3. RIGHT TO REPAYMENT UPON CHANGE IN CONTROL. If a Change of Control shall
occur, Holder shall have the right to require the unpaid principal balance of
the Note, and all accrued and unpaid interest thereon, to become due and payable
in accordance with the terms of Article 8 of the Agreement.

     4. MATURITY. The entire indebtedness hereunder shall become due and payable
July 1, 2005, if not previously paid in full or brought to maturity by the
provisions herein for acceleration.

     5. PREPAYMENT. Payment of any installment of principal may be made in whole
or in part prior to the date when payment thereof shall become due without
penalty or premium.

     6. COMPUTATION OF INTEREST. Interest due hereunder shall be computed on the
per annum basis of a year of three hundred sixty (360) days for the actual
number of days (including the first day but excluding the last day), elapsed.

     7. INTEREST RATE LIMIT. Notwithstanding any other provision herein or in
any related document, Holder shall not be entitled to contract for, charge,
take, reserve, receive or apply as interest on the indebtedness any amount in
excess of the sum corresponding to the highest rate of interest allowable under
applicable law (hereinafter, "the Highest Lawful Rate"); and in the event that
Holder contracts for, charges, takes, reserves, receives or applies as interest
any such amount, it shall be deemed a partial prepayment of principal and
treated hereunder as such; and, if the indebtedness is paid and performed in
full, any remaining excess shall forthwith be paid to the Maker. In determining
whether or not the interest paid or payable, under any specific contingency,
exceeds the Highest Lawful Rate, Holder and the Maker shall, to the maximum
extent permitted under applicable law, (i) treat all loans by Holder to Maker as
but a

                                       2
<Page>

single extension of credit, (ii) characterize any nonprincipal payment as
an expense or fee rather than as interest, (iii) exclude voluntary prepayments
and the effects thereof and (iv) "spread" the total amount of interest
throughout the entire contemplated term of the indebtedness, PROVIDED, THAT if
the indebtedness is paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest received for the actual period of
existence thereof exceeds the Highest Lawful Rate, Holder shall refund such
excess and, in such event, Holder shall not be subject to any penalties provided
by any laws limiting rates of interest.

     8. OTHER PAYMENT PROVISIONS. The Maker shall make each payment hereunder
not later than 4:00 P.M. (Eastern time) on the day when due, without offset, in
lawful money of the United States of America to the Holder in same day funds.
All payments will be applied first to costs and fees owing hereunder, second to
the payment of interest accrued through the date of payment and third to the
payment of principal. If the date for any payment or prepayment hereunder falls
on a day which is not a business day, then for all purposes of this Note the
same shall be deemed to have fallen on the next business day, and such extension
of time shall be included in the computation of interest.

     9. DEFAULT AND ACCELERATION. If payments are not made within thirty (30)
days of the due date of any principal or interest installment as and when
provided herein, or if any other Event of Default, as defined in the Agreement,
should occur then by written notice to Maker a default may be declared at the
option of the Holder without presentment, demand, protest, or further notice of
any kind (all of which are hereby expressly waived). In such event and upon such
declaration having been made, the full balance of the indebtedness hereunder
may, at Holder's option, become due and payable, including all unpaid principal
amounts, accrued interest and any costs (including reasonable attorneys' fees),
and the Holder shall be entitled to any other remedies which may be available
hereunder, under the Agreement, the other Loan Documents, or any applicable law.

     10. NO IMPLIED WAIVER. No course of dealing between the Holder and any
other party hereto or any failure or delay on the part of the Holder in
exercising any rights or remedies hereunder shall operate as a waiver of any
rights or remedies of the Holder under this or any other applicable instrument.
No single or partial exercise of any rights or remedies hereunder shall operate
as a waiver or preclude the exercise of any other rights or remedies hereunder.

parties hereto determined, in accordance with the laws of the District of

adjudication hereof may be in the courts of the District of Columbia or the
Federal courts in the District of Columbia, to the jurisdiction of which courts
the Maker hereby submits, as the agreement of such party, as not inconvenient
and as not subject to review by any court other than such courts in the District
of Columbia. The Maker intends and agrees that the courts of the jurisdictions
in which the Maker is incorporated and conducts business shall afford full faith
and credit to any judgment rendered by a court of the District of Columbia
against the Maker hereunder, and that such District of Columbia and federal
courts shall have IN PERSONAM

Default or an Event of Default, for the enforcement or preservation of Holder's
rights under this Note, including but not limited to reasonable attorneys' fees,

document amendment, involving the Maker or any other obligor under the Note.
