         FOR VALUE RECEIVED, the undersigned, SKY ALLAND RESEARCH, INC., a
Maryland corporation, and THE DATA GROUP II, INC., a Maryland corporation,
(collectively the "Borrowers" and each a "Borrower"), jointly and severally,
promise to pay to the order of SILICON VALLEY BANK, a California-chartered bank
("Bank"), at such place as the holder hereof may designate, in lawful money of
the United States of America, the aggregate unpaid principal amount of all
advances ("Equipment Advances") made by Bank to Borrowers in accordance with the
terms and conditions of the Loan and Security Agreement among Borrowers and Bank
dated as of May 28, 1998 (as amended from time to time, the "Loan Agreement"),
up to a maximum principal amount of One Million and No/100 Dollars
($1,000,000.00) ("Principal Sum"), or so much thereof as may be advanced.
Equipment Advances may be made under this Note only after the date hereof and on
or before February 28, 2000 (the "Tranche One End Date").

         Borrowers shall pay interest on the outstanding Principal Sum, as
follows:

         Commencing as of the date hereof and continuing until repayment in full
of all sums due hereunder, the unpaid Principal Sum shall bear interest at the
variable rate of interest, per annum, most recently announced by Bank as its
"prime rate," whether or not such announced rate is the lowest rate available
from Bank (the "Prime Rate"), plus three quarters of one percent (.75%) per
annum. The rate of interest charged under this Note shall change immediately and
contemporaneously with any change in the Prime Rate. All interest payable under
the terms of this Note shall be calculated on the basis of a 360-day year and
the actual number of days elapsed.

         The unpaid Principal Sum, together with interest thereon at the rate or
rates provided above, shall be payable as follows:

         (a) Interest only on the unpaid principal amount shall be due and
payable monthly in arrears, commencing on December 5, 1999, and continuing on

<PAGE>

         (b) In addition to the monthly payments of interest as set forth above,
the unpaid Principal Sum shall be due and payable in equal consecutive monthly
installments in an amount equal to one-thirty sixth (1/36) of the unpaid
Principal Sum as of the Tranche One End Date, commencing on March 5, 2000 and
continuing on the same day of each calendar month thereafter to maturity; and

         (c) Unless sooner paid, the unpaid Principal Sum, together with
interest accrued and unpaid thereon, shall be due and payable in full on
February 5, 2003.

         This Note reduces, amends and restates in its entirety that certain
Amended and Restated Equipment Note No. 1 of 2 (the "Amended Equipment Term Note
No. 1") in the maximum principal amount of Two Million Dollars ($2,000,000)
dated as of December ___, 1998 from the Borrowers in favor of the Bank. It is
expressly agreed that the indebtedness evidenced by the Amended Equipment Term
Note No. 1 has not been extinguished or discharged hereby. The Borrowers agree
that the execution of this Agreement is not intended to and shall not cause or
result in a novation with respect to Amended Equipment Term Note No. 1. As of
the date hereof, the unpaid principal balance of Equipment Term Note No. 1 is
$0, and the Borrowers have no set offs or defenses to the payment thereof.

         From and after the date hereof, this Note shall be the "Equipment Term
Note No. 1" described in the Loan Agreement, to which reference is hereby made
for a more complete statement of the terms and conditions under which the loans
and advances evidenced hereby are made. This Note is secured as provided in the
Loan Agreement. All capitalized terms used herein and not otherwise defined
shall have the meanings given to such terms in the Loan Agreement.

         Borrowers irrevocably waive the right to direct the application of any
and all payments at any time hereafter received by Bank from or on behalf of the
Borrowers and the Borrowers irrevocably agree that Bank shall have the
continuing exclusive right to apply any and all such payments against the then
due and owing obligations of the Borrowers as Bank may deem advisable. In the
absence of a specific determination by Bank with respect thereto, all payments
shall be applied in the following order: (a) then due and payable fees and
expenses; (b) then due and payable interest payments and mandatory prepayments;
and (c) then due and payable principal payments and optional prepayments.

         Bank is hereby authorized by Borrowers to endorse on Bank's books and
records each Equipment Advance made by Bank under this Note and the amount of
each payment or prepayment of principal of each such Equipment Advance received
by Bank; it being understood, however, that failure to make any such endorsement
(or any error in notation) shall not affect the obligations of the Borrowers
with respect to Equipment Advances made hereunder, and

                                      - 2 -

payments of principal by Borrowers shall be credited to Borrowers
notwithstanding the failure to make a notation (or any errors in notation)
thereof on such books and records.

         The occurrence of any one or more of the following events shall
constitute an event of default (individually, an "Event of Default" and
collectively, the "Events of Default") under the terms of this Note:

         (a) The failure of Borrowers to pay to Bank when due any and all
amounts payable by Borrowers to Bank under the terms of this Note; or

         (b) The occurrence of an Event of Default (as defined therein) under
the terms and conditions of any of the other Loan Documents.

         Upon the occurrence of an Event of Default, at the option of Bank, all
amounts payable by Borrowers to Bank under the terms of this Note shall
immediately become due and payable by Borrowers to Bank without notice to
Borrowers or any other Person, and Bank shall have all of the rights, powers,
and remedies available under the terms of this Note, any of the other Loan
Documents and all applicable laws. Borrowers and all endorsers, guarantors, and
other parties who may now or in the future be primarily or secondarily liable
for the payment of the indebtedness evidenced by this Note hereby severally
waive presentment, protest and demand, notice of protest, notice of demand and
of dishonor and non-payment of this Note and expressly agree that this Note or
any payment hereunder may be extended from time to time without in any way
affecting the liability of Borrowers, guarantors and endorsers.

         Upon the occurrence of an Event of Default, Borrowers hereby authorize
any attorney designated by Bank or any clerk of any court of record to appear
for Borrowers in any court of record and confess judgment without prior hearing
against Borrowers in favor of Bank for and in the amount of the unpaid Principal
Sum, all interest accrued and unpaid thereon, all other amounts payable by
Borrowers to Bank under the terms of this Note or any of the other Loan
Documents, costs of suit, and attorneys' fees of fifteen percent (15%) of the
unpaid Principal Sum and interest then due hereunder. Borrowers hereby release,
to the extent permitted by applicable law, all errors and all rights of
exemption, appeal, stay of execution, inquisition, and other rights to which
Borrowers may otherwise be entitled under the laws of the United States of
America or of any state or possession of the United States of America now in
force and which may hereafter be enacted. The authority and power to appear for
and enter judgment against Borrowers shall not be exhausted by one or more
exercises thereof or by any imperfect exercise thereof and shall not be
extinguished by any judgment entered pursuant thereto. Such authority may be
exercised on one or more occasions or from time to time in the same or different
jurisdictions as often as Bank shall deem necessary or desirable, for all of
which this Note shall be a sufficient warrant.
