from time to time, the principal sum of Four Hundred Eight Thousand Seven
Hundred Two and 60/100 DOLLARS ($408,702.60), or so much as may be advanced
hereunder, payable with interest as provided below. The proceeds of the loan
("Loan") evidenced by this Note are to be advanced under the terms and
conditions of the Loan and Pledge Agreement ("Pledge Agreement") between Lender
and Borrower dated the same date as this Note.

1.    Definitions

      Except as set forth in this Note, capitalized terms shall have the

following terms shall have the definitions set forth below:

      "Business Day" means any day, other than Saturday, Sunday or a day on
which national banks in Seattle, Washington are authorized or required by law to
be closed.

      "Loan Documents" means this Note, the Pledge Agreement, and all related
documents.

      "Maturity Date" means the earlier of (i) October 26, 2002, (ii) the date

which Avenue A demands repayment.

2.    Interest

            (a) This Note shall bear interest at the rate of 9% per annum.

            (b) All computations of interest and fees shall be based on a
360-day year for the actual number of days elapsed.

            (c) Notwithstanding any provision contained herein or in the Note,
the total liability of Borrower for payment of interest pursuant hereto,
including late charges, shall not exceed the maximum amount of interest
permitted by applicable law to be charged, collected
<PAGE>

or received from Borrower; and if any payments by Borrower include interest in
excess of that maximum amount, Lender shall apply the excess first to reduce the
unpaid balance of the Loan, then the excess shall be returned to Borrower.

3.    Payments

      3.1   Time and Place of Payments

            (a) Borrower's interest obligations under this Note shall be due
upon the Maturity Date, at which time all sums due hereunder shall be paid in
full.

            (b) All payments made hereunder shall be delivered to Lender at the
address set forth above, or at a different place required by Lender or by any
other party who takes this Note by transfer and who is entitled to receive
payment ("Holder").

            (c) All sums payable hereunder shall be paid in immediately
available United States funds.

            (d) Whenever any payment to be made hereunder or on the Note becomes
due and payable on a day that is not a Business Day, such payment may be made on
the next succeeding Business Day and such extension of time shall in such case
be included in computing interest on such payment.

      3.2   Application of Payments

      Payments shall be applied in the following order: (1) to the payment of
late charges, if any; (2) to the payment of accrued interest, computed on a
360-day yearly basis and collected for the actual number of days in the month,
based on the outstanding principal balance to the due date; (3) at the option of
Holder, to the payment of any advances the Holder may have made for taxes,
assessments, insurance premiums, or other charges on any property given as
security herefor; and (4) to the reduction of the principal balance.

4.    Prepayment

      Borrower shall have the right, at any time, to prepay the whole or any
part the principal hereof without prepayment charges. All prepayments shall be
credited first upon accrued interest and then upon the last maturing installment
of principal. If Borrower makes such a partial prepayment, there will be no
changes in the due dates of the monthly payments unless Lender agrees in writing
to those changes. When a prepayment is made by Borrower, Borrower will tell
Lender in writing that Borrower is doing so.

      This Note is secured by the Pledge Agreement, pledging the Pledged Shares.
<PAGE>

6.    Events of Default

      The occurrence of either of the following shall constitute an "Event of
Default" under this Note: (i) the failure by Borrower to make any payment under
this Note upon the date it is due, or (ii) the occurrence of an Event of Default
as defined in any of the other Loan Documents.

7.    Remedies; Default Interest

      Upon the occurrence of any Event of Default, Lender may declare the entire
principal balance and all accrued interest immediately due and payable. Whether
or not Lender exercises such option to accelerate upon the occurrence of any
Event of Default, the entire principal balance and all accrued interest under
the Loan and all other amounts payable under the Loan Documents shall bear
interest from the date of the Event of Default at a default rate equal to 5
percent plus the rate of interest otherwise payable under this Note. Such
default interest shall be payable on demand. Lender's failure to exercise any
right or remedy shall not be a waiver of the right to exercise the same upon any
subsequent Event of Default. The foregoing remedies shall be in addition to all
other legal and equitable rights and remedies of Lender.

8.    General

      (a) Waivers. Except as otherwise provided in the Loan Documents, Borrower
waives all notices required by law; including without limitation presentment and
demand for payment, protest, and notice of demand, protest, dishonor and
nonpayment.

      (b) Costs and Attorney's Fees. Upon the occurrence of any Event of
Default, Lender shall have the right, at Borrower's expense, to consult an
attorney or collection agency, to make any demand, enforce any remedy, or
otherwise protect its rights under this Note and the Loan Documents. Borrower
hereby promises to pay all costs, fees, and expenses so incurred by Lender,
including, without limitation, reasonable attorney fees (with or without
arbitration or litigation), arbitration and court costs, collection agency
charges, notice expenses and title search expenses, and the failure of the
defaulting Borrower to pay the same shall, in itself, constitute a further and
additional default. In the event that suit or action or arbitration is
instituted by Lender to enforce this Note or any rights under the Loan
Documents, Borrower hereby promises to pay, in addition to costs and expenses
provided by statute or otherwise, such sums as the court or arbitrator may
adjudge reasonable as attorney fees in such proceeding and on any appeals from
any judgment or decree entered therein and the reasonable costs and attorney
fees for collection of the amount due therein; provided that if either Borrower
or Lender institute any action or arbitration under the Loan Documents, the
prevailing party in any such action or arbitration shall be entitled to such
costs and fees, including attorney fees, as the court or arbitrator may adjudge
as reasonable in such proceeding. Borrower further agrees to pay immediately
upon demand all costs and expenses of Lender including reasonable attorney fees:
(i) if Lender seeks to have the property securing the Loan abandoned by any
estate in bankruptcy; (ii) if Lender attempts to have any
<PAGE>

stay or injunction prohibiting the enforcement or collection of the Note or
prohibiting the enforcement of any other Loan Document lifted by any bankruptcy
or other court; (iii) if Lender participates in any subsequent proceedings or
appeal from any order or judgment entered in any such proceeding; (iv) if Lender
deems it appropriate to file a proof of claim or in any other manner participate
in any bankruptcy or similar proceedings; or (v) if Lender retains legal counsel
in connection with any amendments or modifications to this Note or any other
Loan Document.

      (c) Waiver of Jury Trial. BORROWER, AND LENDER BY ITS ACCEPTANCE OF THIS
NOTE, HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM

THE LOAN TRANSACTION CONTEMPLATED BY THE LOAN DOCUMENTS OR THE LENDING
RELATIONSHIPS THAT ARE BEING ESTABLISHED. The scope of this waiver is intended
to be all-encompassing of any and all disputes that may be filed in any court
and that relate to the subject matter of this transaction, including without
limitation, contract claims, tort claims, breach of duty claims, and all other
common law and statutory claims. Borrower, and Lender by its acceptance of this
Note, acknowledges that this waiver is a material inducement to enter into a
business relationship, that each has already relied on this waiver in making and
accepting this Note, and that each will continue to rely on this waiver in their
related future dealings. Borrower, and Lender by its acceptance of this Note,
further warrants and represents that it has reviewed this waiver with its legal
counsel and that it knowingly and voluntarily waives its jury trial rights
following consultation with legal counsel. THIS WAIVER IS IRREVOCABLE, MEANING
THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL
APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS, OR MODIFICATIONS TO
THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR TO ANY OTHER DOCUMENTS OR
AGREEMENTS RELATING TO THE LOAN MADE HEREUNDER. In the event of litigation, this
agreement may be filed as a written consent to a trial by the court.

OF OR RELATING TO THIS NOTE MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION IN THE STATE OF WASHINGTON, AND BY EXECUTION AND DELIVERY

may be made by registered or certified mail, return receipt requested, to
Borrower at its address as provided in the Loan Documents, and Borrower hereby
acknowledges that such service shall be effective and binding in every respect.

                                GENERAL RELEASE

     THIS SEPARATION AGREEMENT AND GENERAL RELEASE (the "Agreement") is entered
into by Robert M. Littauer (hereinafter referred to as "EXECUTIVE") and Avenue
A, Inc. (hereinafter referred to as "THE COMPANY").

                                    RECITALS

     A.   EXECUTIVE has been employed by THE COMPANY and his employment
relationship with THE COMPANY shall terminate effective October 19, 2000 (the
"Termination Date").

     B.   EXECUTIVE and THE COMPANY wish to enter into an agreement to clarify
and resolve any disputes that may exist between them arising out of the
employment relationship and its termination, and any continuing obligations of
the parties to one another following the end of the employment relationship.

     C.   THE COMPANY has advised EXECUTIVE of his right to consult an attorney
prior to signing this Agreement and has provided him with at least 21 days to
consider its severance offer and to seek legal assistance.  EXECUTIVE has either
consulted an attorney of his choice or voluntarily elected not to consult legal
counsel, and understands that he is waiving all potential claims against THE
COMPANY.

     D.   This Agreement is not and should not be construed as an admission or
statement by either party that it or any other party has acted wrongfully or
unlawfully.  Both parties expressly deny any wrongful or unlawful action.

                                  AGREEMENTS

     NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
promises contained below, it is agreed as follows:

     1.   EMPLOYMENT:  ENDING DATE AND RESPONSIBILITIES

     EXECUTIVE's employment with THE COMPANY shall terminate effective October
19, 2000. Effective September 18 , 2000, EXECUTIVE shall have no further
employment duties or responsibilities to THE COMPANY.

     2.   CHARACTERIZATION OF TERMINATION

     EXECUTIVE and THE COMPANY agree that for all future purposes they will
characterize his termination of employment as a voluntary resignation.
<PAGE>

     3.   SEVERANCE AND BENEFITS

     Commencing on the Termination Date, THE COMPANY will pay to EXECUTIVE 12
months' salary as severance, in addition to his salary through the Termination
Date, such payments to be made in accordance with THE COMPANY's regular payroll.
THE COMPANY will also pay EXECUTIVE's COBRA premiums for health insurance
benefit continuation through October 31, 2001.  All other benefits shall cease
effective the date that employment terminated, except EXECUTIVE's right to self-
pay health insurance benefits under COBRA beyond October 31, 2001, if he elects
to do so.

     In addition, EXECUTIVE shall receive one-year's accelerated vesting on all
outstanding option shares in Avenue A common stock.  Specifically, (1) the
portion of any Avenue A stock option held by Executive immediately prior to the
Termination Date, that is unvested shall automatically vest, immediately prior
to the Termination Date, in an amount equal to the portion that would have
vested in the period commencing on the Termination Date and ending on the one-
year anniversary of the Termination Date, had EXECUTIVE'S employment continued
through the latter date; and (2) the number of unvested shares, if any, held by
Executive immediately prior to the Termination Date that were obtained on
exercise of any Avenue A stock options that is equal to the number of such
unvested shares that would have vested during in the period commencing on the
Termination Date and ending on the one-year anniversary of the Termination Date,
had EXECUTIVE'S employment continued through the latter date, shall, immediately
prior to the Termination Date, automatically vest and be no longer subject to
the right of repurchase in favor of Avenue A.  Because the one-year anniversary
of the Termination Date falls between vesting milestones, the vesting
acceleration described above shall be pro rated to include a partial
acceleration for the number of days between the beginning of the last quarter
falling within the one-year acceleration period and the one-year anniversary of
the Termination Date.

     4.   VALID CONSIDERATION

     EXECUTIVE and THE COMPANY agree that payment by THE COMPANY to EXECUTIVE of
the amounts described in the preceding paragraph is not required by THE COMPANY
policies or procedures or by any contractual obligation of THE COMPANY, and is
offered by THE COMPANY solely as consideration for this Agreement.

                                      -2-

     5.   REAFFIRMATION OF CONFIDENTIALITY AGREEMENT

     EXECUTIVE expressly reaffirms the Confidentiality Agreement that he signed
as part of his employment with THE COMPANY, a copy of which is attached as
Exhibit A and which shall remain in full effect.  EXECUTIVE confirms that he has
or will immediately upon termination turn over to THE COMPANY all files,
memoranda, records, credit cards, and other documents or physical property which
he received from THE COMPANY or its Employees or generated himself in the course
of his employment with THE COMPANY.

     6.   CONFIDENTIALITY OF SEPARATION AGREEMENT

     EXECUTIVE agrees that he will keep the terms of this Agreement (including
but not limited to the severance amount) completely confidential, and that he
will not disclose any information concerning this Agreement or its terms to
anyone other than his immediate family, legal counsel, and/or financial
advisors, who will be informed of and bound by this confidentiality clause.

     7.   GENERAL RELEASE OF CLAIMS

     EXECUTIVE expressly waives any claims against THE COMPANY and releases THE
COMPANY (including its officers, directors, stockholders, managers, agents and
representatives) from any claims that he may have in any way connected with his
employment with THE COMPANY and the termination thereof.  It is understood that
this release includes, but is not limited to, any claims for wages, bonuses,
employment benefits, or damages of any kind whatsoever, arising out of any
contracts, express or implied, any covenant of good faith and fair dealing,
express or implied, any theory of wrongful discharge, any legal restriction on
THE COMPANY's right to terminate employment, or any federal, state or other
governmental statute or ordinance, including, without limitation, Title VII of
the Civil Rights Act of 1964, the federal Age Discrimination in Employment Act,
the Americans with Disabilities Act, the Family and Medical Leave Act, the
Washington Law Against Discrimination, or any other legal limitation on the
employment relationship.

     EXECUTIVE represents that he has not filed any complaints, charges or
lawsuits against THE COMPANY with any governmental agency or any court, and
agrees that he will not initiate, assist or encourage any such actions.

     This waiver and release shall not waive or release claims where the events
in dispute first arise after execution of this Agreement, nor shall it preclude
EXECUTIVE from filing a lawsuit for the exclusive purpose of enforcing his
rights under this Agreement.

                                      -3-

THE COMPANY and supersedes any prior agreements or understandings, express or
implied, pertaining to the terms of his employment with THE COMPANY and the
termination of the employment relationship.  EXECUTIVE acknowledges that in
executing this Agreement, he does not rely upon any representation or statement
by any representative of THE COMPANY concerning the subject matter of this
Agreement, except as expressly set forth in the text of the Agreement.
