     Re:  Separation of Employment

Dear Richard:

     Your employment with Roving Software, Inc. ("Constant Contact" or "the
Company") and Administaff is being terminated. The purpose of this letter is to
establish an amicable arrangement for ending your employment in a manner that
will permit you to obtain certain payments and other benefits in return for,
among other things, your release of any claims against the Company.

     Your final day of employment will be January 1, 2007 ("Separation Date").

     You will receive your final paycheck according to the regular payroll
cycle. It will be comprised of: (1) all salary due and owing to you through the
Separation Date, less applicable state and federal taxes and other deductions;
and (2) payment equal to the value of all accrued, unused vacation through the
Separation Date, less applicable state and federal taxes and other deductions.
Administaff will provide you with written documentation concerning your right to
unemployment benefits.

     Following the Separation Date, the Company will continue to maintain you as
eligible for participation its health insurance plan as required by, and insofar
as you elect coverage under, the Consolidated Omnibus Budget Reconciliation Act
of 1985 (often referred to as "COBRA"). Information concerning your insurance
continuation under COBRA will be provided to you separately. Your coverage under
all other Company-sponsored insurance plans will expire on the Separation Date,
unless otherwise specified by applicable plan documents.

     If you are enrolled in the Company's group health and dental plans on the
Separation Date and elect, no later than the effective date of this Agreement,
to continue your coverage and that of your eligible dependents in those plans
under the federal law known as "COBRA," the Company will pay the premium cost of
that coverage through June 30, 2007 or, if less, until the date you become
eligible for coverage under the health and/or dental plan of another employer.
You agree to notify Constant Contact immediately if you become eligible for
health and/or dental coverage from another employer during the ninety days
following the Separation Date and to repay any excess contributions made by the
Company. After the Company's contributions end, you may continue coverage for
the remainder of the COBRA period, if any, by paying the full premium cost plus
a small administrative fee.

     Additionally, if you are interested in converting your group life insurance
into an individual policy, please contact human resources.

<PAGE>

     Except for funds that may have vested in the Company-sponsored benefit
plans or expressly referenced in this letter, you will not be entitled to any
other compensation or benefits. To the extent you have any stock options, you
are advised to refer to the applicable stock option agreements and plan for
guidance as to your rights and obligations.

     You must immediately turn over all confidential information and property
belonging to the Company, including, without limitation, all records, files,
memoranda, notes, designs, data, reports, price lists, customer lists, drawings,
plans, computer programs, software, software documentation, hardware, sketches,
laboratory and research notebooks and other documents, as well as all copies or
reproductions of such material relating to the business of the Company. You are
also advised that you will be expected to abide by your obligations under your
Nondisclosure, Non-competition and Developments Agreement, a copy of which is
attached.

     The Company offers you the opportunity to obtain severance pay equivalent
to six months of base salary, less appropriate federal and state taxes and other
deductions ("Severance Benefits"). YOU WILL BE ENTITLED TO THE SEVERANCE
BENEFITS ONLY IF YOU AGREE TO THE FOLLOWING ADDITIONAL TERMS AND CONDITIONS,
TIMELY EXECUTE THIS AGREEMENT AND DO NOT REVOKE IT DURING THE SEVEN-DAY
REVOCATION PERIOD (EXPLAINED IN MORE DETAIL BELOW). The Company will pay the
Severance Benefits in a lump sum of $82,500.00 within a reasonable period of
time after this agreement becomes enforceable and non-revocable.

     Additionally you will be eligible for a 2006 fourth quarter bonus based on
your fourth quarter targeted AMRG incentive, subject to the terms of the
existing plan. This payment will be made to you in accordance to the regular
payroll cycle for performance bonuses in 2007. You are also eligible to receive
up to 3 months of outplacement services through ClearRock.

     In exchange for the Severance Benefits, you agree and/or acknowledge the
following:
