                                [FACILITY A NOTE]

$22,500,000                                                      October 1, 2002

     FOR VALUE RECEIVED, after date, without grace, in the manner, on the dates
and in the amounts so herein stipulated, the undersigned, EQUUS II INCORPORATED,
a Delaware corporation, acting by and through its duly authorized officer
("Borrower"), PROMISES TO PAY TO THE ORDER OF BANK OF AMERICA, N.A. ("Lender"),
in Houston, Harris County, Texas, the sum of TWENTY-TWO MILLION FIVE HUNDRED
THOUSAND AND 00/100 DOLLARS ($22,500,000) or, if less, the aggregate unpaid
principal amount of advances made by Lender to Borrower pursuant to this Note,
in lawful money of the United States of America, which shall be legal tender in
payment of all debts and dues, public and private, at the time of payment, and
to pay interest on the unpaid principal amount from date until maturity at a
rate equal to the Stated Rate (as defined in the Loan Agreement described
herein), not to exceed the maximum non-usurious interest rate permitted by
applicable law from time to time in effect as such law may be interpreted,
amended, revised, supplemented or enacted ("Maximum Rate"), provided that if at
any time the Stated Rate exceeds the Maximum Rate then interest hereon shall
accrue at the Maximum Rate. In the event the Stated Rate subsequently decreases
to a level which would be less than the Maximum Rate or if the Maximum Rate
applicable to this Note should subsequently be changed, then interest hereon
shall accrue at a rate equal to the applicable Maximum Rate until the aggregate
amount of interest so accrued equals the aggregate amount of interest which
would have accrued at the Stated Rate without regard to any usury limit, at
which time interest hereon shall again accrue at the Stated Rate. This Note is
payable as follows:

          The entire balance of principal and accrued interest shall be due and
     payable on the 1st day of January, 2003.

     It is agreed that time is of the essence of this agreement. In the event of
default in the payment of any installment of principal or interest when due or
in the event of any other default hereunder, Lender may accelerate and declare
this Note immediately due and payable without notice. Any failure to exercise
this option shall not constitute a waiver by Lender of the right to exercise the
same at any other time.

     In the event of default in the making of any payment herein provided,
either of principal or interest, or in the event this Note is declared due,
interest shall accrue at Prime Rate plus 2% not to exceed the Maximum Rate.

     Borrower hereby agrees to pay all expenses incurred, including reasonable
attorneys' fees, all of which shall become a part of the principal hereof, if
this Note is placed in the hands of an attorney for collection or if collected
by suit or through any probate, bankruptcy or any other legal proceedings.

     Interest charges will be calculated on amounts advanced hereunder on the
actual number of days these amounts are outstanding on the basis of a 360-day
year, except for calculations of the Maximum Rate which will be on the basis of
a 365-day or 366-day year, as is applicable. It is the intention of the parties
hereto to comply with all applicable usury laws; accordingly, it is

                                        1

<PAGE>

agreed that notwithstanding any provision to the contrary in this Note, or in
any of the documents securing payment hereof or otherwise relating hereto, no
such provision shall require the payment or permit the collection of interest in
excess of the Maximum Rate. If any excess of interest in such respect is
provided for, or shall be adjudicated to be so provided for, in this Note or in
any of the documents securing payment hereof or otherwise relating hereto, then
in such event (1) the provisions of this paragraph shall govern and control, (2)
neither Borrower, endorsers or guarantors, nor their heirs, legal
representatives, successors or assigns nor any other party liable for the
payment hereof, shall be obligated to pay the amount of such interest to the
extent that it is in excess of the Maximum Rate, (3) any such excess which may
have been collected shall be either applied as a credit against the then unpaid
principal amount hereof or refunded to Borrower, and (4) the provisions of this
Note and any documents securing payment of this Note shall be automatically
reformed so that the effective rate of interest shall be reduced to the Maximum
Rate. For the purpose of determining the Maximum Rate, all interest payments
with respect to this Note shall be amortized, prorated and spread throughout the
full term of the Note so that the effective rate of interest on account of this
Note is uniform throughout the term hereof.

     Borrower agrees that the Maximum Rate to be charged or collected pursuant
to this Note shall be the applicable indicated rate ceiling as defined in the
Texas Finance Code, as supplemented by Article 1D.003 of the Texas Credit Title,
provided that Lender may rely on other applicable laws, including without
limitation laws of the United States, for calculation of the Maximum Rate if the
application thereof results in a greater Maximum Rate. Except as provided above,
the provisions of this Note shall be governed by the laws of the State of Texas.

     Each maker, surety, guarantor and endorser (i) waives demand, grace,
notice, presentment for payment, notice of intention to accelerate the maturity
hereof, notice of acceleration of the maturity hereof and protest, (ii) agrees
that this Note and the liens securing its payment may be renewed, and the time
of payment extended from time to time, without notice and without releasing any
of the foregoing, and (iii) agrees that without notice or consent from any
maker, surety, guarantor, or endorser, Lender may release any collateral which
may from time to time be pledged to secure repayment of this Note, or may
release any party who might be liable for this Note. Borrower grants to Lender a
lien on any of Borrower's funds which may from time to time be deposited with
Lender.

     Borrower may prepay this Note, in whole or in part, at any time prior to
maturity without penalty, and interest shall cease on any amount prepaid. Any
partial prepayment shall be applied toward the payment of the principal
installments last maturing on the Note, that is, in the inverse order of
maturity, without reducing the amount or time of payment of the remaining
installments.

     The principal of this Note represents funds which Lender will advance to
Borrower from time to time upon request of Borrower. Any part of the principal
may be repaid by Borrower and thereafter reborrowed, provided the outstanding
principal amount of this Note shall never exceed the face amount of this Note.
Each advance shall constitute a part of the principal hereof and shall bear
interest from the date of the advance. The provisions of Tex. Rev. Civ. Stat.
Ann. art. 5069-15.01, et seq., as may be amended, shall not apply to this Note
or to any of the security documents executed in connection with this Note.
