                     AMENDED AND RESTATED PROMISSORY NOTE


$29,013.00 (U.S.)                                        Seattle, Washington

                                     Original Issuance Date: October 8, 1999

                                         Amended and Restated: July 16, 2001

         For value received, the undersigned, Michael Galgon, promises to
pay on demand to the order of Avenue A, Inc., a Washington corporation (the
"Company"), the principal sum of Twenty Nine Thousand Thirteen Dollars
($29,013.00) with interest compounded annually from the original issuance
date (the "Original Issuance Date") at a rate equal to the greater of (i)
the applicable federal funds rate as determined on the Original Issuance
Date and redetermined each year on the anniversary date of the Original
Issuance Date, or (ii) the lowest rate necessary to avoid the imputation of
interest under the Internal Revenue Code of 1986, as amended, from the
Issuance Date on the unpaid balance until this Amended and Restated
Promissory Note (this "Note"), including the interest thereon, is paid in
full or forgiven in accordance with the terms hereof, such interest to be
paid annually on each anniversary date of this Note.

         If payment of any sum is not made within ten days after demand,
then this Note shall be in default, and, at the option of the holder hereof,
without prior notice, the principal sum and interest shall bear interest
from such default until paid at the rate of twelve percent (12%), compounded
quarterly, or the maximum rate permitted by law, whichever is less.

         Principal and interest are payable in lawful money of the United
States of America at such place as the holder may designate. All payments of
principal and interest hereunder shall be applied first against accrued
interest and then against principal. The undersigned shall have the right,
upon payment of all accrued interest to the date of payment, to pre-pay at
any time in advance of maturity, without premium or penalty, all or any part
of the outstanding principal amount of this Note.

         One-third of the principal balance outstanding on January 1, 2002
and all accrued interest as of such date shall be forgiven on such date if
the undersigned continues to be employed by the Company as of January 1,
2002, one-half of the principal balance outstanding on January 1, 2003 and
all accrued interest as of such date shall be forgiven on such date if the
undersigned continues to be employed by the Company as of January 1, 2003,
and any remaining principal amount and accrued interest shall be forgiven on
January 1, 2004 if the undersigned continues to be employed by the Company
as of January 1, 2004. Promptly after each date on which an amount hereunder
is forgiven in accordance with the preceding sentence, the Company shall
provide to the undersigned, on a "grossed up" basis, an amount equal to the
amount of applicable federal taxes that the undersigned shall owe in respect
of any amounts forgiven on such date (including any taxes on "gross up"
payments).
<PAGE>

Such amounts shall be deposited into an appropriate withholding account on
behalf of the undersigned.

         If the undersigned voluntarily resigns or is terminated for "Cause"
(as that term is defined in Exhibit A hereto ("Cause")), the outstanding
principal amount and accrued interest shall become immediately due and
payable without notice. If (a) the undersigned is terminated without
"Cause," (b) the undersigned is subject to a "Total Disability" (as that
term is defined in Exhibit A hereto), (c) a "Corporate Transaction" (as that
term is defined in Exhibit A hereto) occurs, or (d) the Company winds up its
operations and ceases doing business, then in any such case any outstanding
principal amount plus accrued interest shall be forgiven and the Company
shall promptly thereafter provide to the undersigned, on a "grossed up"
basis, an amount equal to the amount of applicable federal taxes that the
undersigned shall owe in respect of any amounts so forgiven (including any
taxes on "gross up" payments). Such amounts shall be deposited into an
appropriate withholding account on behalf of the undersigned.

         If suit is brought on this Note, or if it is placed in the hands of
an attorney for collection, after any default in any payment, the
undersigned promises and agrees to pay all costs of collection, including
attorneys' fees, incurred thereby. Such costs of collection include, without
limitation, any attorneys' fees and costs incurred by the holder in a
bankruptcy case or proceeding in which the undersigned is a debtor.

         This Note is with full recourse against the undersigned. This Note
is to be construed in all respects and enforced according to the laws of the
State of Washington, without regard for any choice of law rules that might
be asserted to subject this Note to the laws of any other jurisdiction.
Presentment, notice of dishonor and protest are waived by the undersigned.


                                      -2-

         This Note shall be fully binding on and inure to the benefit of the
successors, heirs, legal representatives and assigns of the parties hereto.
This Note supercedes and replaces in its entirety the promissory note issued
by the Company to the undersigned on October 8, 1999.

ORAL AGREEMENTS OR ORAL COMMITMENTS TO LOAN MONEY, EXTEND CREDIT, OR TO
FORBEAR FROM ENFORCING REPAYMENT OF A DEBT ARE NOT ENFORCEABLE UNDER
WASHINGTON LAW.

         below);

            (b) willful actions (or intentional failures to act) in bad faith

            (c) conviction of a felony involving an act of dishonesty, moral

         representing more than sixty percent (60%) of the combined voting power
         the capital stock of such corporation are then beneficially owned,
         directly or indirectly, by all or substantially all of the beneficial
         owners of securities representing the combined voting power of the
         capital stock of the Company (the "Company Voting Securities")

         stock of the corporation resulting from such reorganization, merger or
         consolidation are then beneficially owned, directly, or indirectly, by
         all or substantially all of the individuals and entities who were the
         beneficial owners of Company Voting Securities immediately prior to
         such reorganization, merger or consolidation in substantially the same
         proportion as their ownership, immediately prior to such
         reorganization, merger or consolidation, of Company Voting Securities,
         (B) no Person (excluding the Company, any employee benefit plan (or

         individual whose initial assumption of office occurs as a result of
         either an actual or threatened election contest (as such terms are used
         in Rule 14a-11 of Regulation 14A promulgated under the Securities
         Exchange Act of 1934, as amended (the "Exchange Act")) or other actual

shall be deemed to occur (a) at the end of the calendar month in which the
undersigned's death occurs or (b) provided that an independent physician
appointed by the Company and reasonably acceptable to the undersigned or his
personal representative (the "Independent Physician") has determined in a
written report made available to the undersigned or his personal representative
that the undersigned is unable to perform his or her duties at the Company as a
result of physical or mental illness, loss of legal capacity or any other cause
beyond the undersigned's control, and such disability has been in effect for a
period or periods aggregating ninety (90) calendar days in a 12-month period,
immediately upon notice to the undersigned or his or her personal
representative. Notwithstanding the foregoing, Total Disability shall not
include any temporary illness or condition that prevents the undersigned from
performing his or her duties for a period of no more than 180 days if, in the
opinion of the Independent Physician, the undersigned is reasonably likely to
recover within 180 days or less from the onset of the illness or condition, such
that he or she can permanently resume performance of his or her duties.

         3. The definition of "Corporate Transaction" means either of the
following events:

            (a) Consummation of any merger or consolidation of the Company in
         which the Company is not the continuing or surviving corporation, or

         into cash, securities or other property, if following such merger or
         consolidation the holders of the Company's outstanding voting
         securities immediately prior to such merger or consolidation do not own
         at least 50% of the outstanding voting securities of the surviving
         corporation (or its parent); or

            (b) Consummation of any sale, lease, exchange or other transfer in
         one transaction or a series of related transactions of all or
         substantially all the Company's outstanding securities or all or
         substantially all the Company's assets other than a transfer of the
         Company's securities or assets to a majority-owned "subsidiary
         corporation" (as that term is defined in Section 422 of the Internal
         Revenue Code) of the Company.
