RE:      Offer Letter

This will confirm our offer of employment and the terms of your employment by
Register.com, Inc. (the "Company" or "Employer").

         1. Position and Duties. You will be employed by the Company as an "at
will" employee, with the title of Vice President and Chief Financial Officer.
Your duties will be as directed by, and you will report directly to, Richard D.
Forman, the President and Chief Executive Officer of the Company, or his
designee.

         2. Base Salary. You will be paid a base salary at the annual rate of
$200,000, payable on a bi-weekly basis, less applicable withholdings, based upon
full time employment with the Company and commencing on the date you start your
full time employment. It is understood that you will begin your employment with
the Company on a part-time basis beginning the week of July 10, 2000 as mutually
agreed to by you and by the Company.

         During your part-time employment with the Company, you will be paid at
the rate of $1,153.85 for each day that you work for the Company.

         3. Guaranteed Bonus. You will be guaranteed to receive a bonus at the
annual rate of $100,000 based upon full time employment with the Company. The
bonus will be paid on a monthly basis. You must be actively employed by the
Company at such time to receive the guaranteed bonuses awarded to you and the
bonus will be considered as additional salary in calculating any benefit or
other bonus plan that is tied to salary. The guaranteed bonus is subject to
applicable withholdings.

         4. Senior Executive Bonus. You will be eligible to receive a senior
executive bonus based upon the Company's performance against Company goals. You
must be actively employed by the Company at such time to receive the senior
executive bonus awarded to you. The senior executive bonus is subject to
applicable withholdings.

         5. Review. You will be reviewed approximately every twelve (12) months
from your start date.

         6. Parking expense. The Company will reimburse the cost of your monthly
parking expenses for the duration of your employment.

         7. Vacation and Benefits Packages. You will be eligible to participate
in the Company's standard vacation and benefit packages and all subsequent
revisions thereto as in effect from time to time. In no event, however, shall
you receive less than four weeks of vacation for every year that you work.
Therefore, your vacation allowance will accrue at the rate of 1.66 days per
month.

         8. Medical Insurance. You will be eligible to participate in the firm's
current medical insurance program after a three (3) month waiting period.

         9. Stock Options. Subject to approval of the Compensation Committee,
you shall receive the right (the "Option") to purchase 155,000 shares of common
stock of the Company at the price to be set forth in the Stock Option Agreement.
The Option shall not vest nor be exercisable until six months from the date that
you commence full time employment with the Company (the "Blackout Period"). At
the expiration of the Blackout Period, the Option shall vest and become
exercisable monthly as to approximately [1/42nd] of all shares of common stock
subject to the Option. In the event that you begin employment with the Company
during the week of July 10, 2000, then the strike price of your options will be
the lower of (a) $35 per share or (b) the closing price on the day that the
compensation committee grants you your stock options. In the event that you
begin work during the week of September 5, 2000, then the strike price of your
options will be the lower of (a) the closing price on the date of grant or (b)
the median closing price during the calendar month prior to September 5, 2000.
The Option is subject to the standard terms and conditions of the Company's 2000
Equity Incentive Plan; however, you understand that your stock options will most
likely be treated as non-qualified stock options (NQSO).

         If you are terminated without cause within four (4) months of a change
in control of the Company, all of your unvested options will vest immediately.

         10. Severance. Notwithstanding that your status would be as an at-will
employee, in the event the Company terminates your employment without "cause" at
any time following the start date of your employment, (a) you will be eligible
to receive the base salary and guaranteed bonus to which you would have been
entitled to receive for a period of one full year from the effective date of
notice of termination (b) any Options that would have vested during such one
year period shall be deemed to have vested as of the effective date of
termination.

The term "cause" as used in this Section 10 shall mean: (1) any action by you
constituting fraud, self-dealing, embezzlement, or dishonesty in the course of
your employment hereunder; (2) any conviction of a crime involving moral
turpitude; (3) any action by you constituting sexual harassment or
discrimination in the course of your employment hereunder; (4) any action of
yours, regardless of its relation to your employment, that has brought or
reasonably could bring the Company into substantial public disgrace or
disrepute; (5) failure by you to take and pass any randomly administered drug
test; (6) failure by you after reasonable written notice promptly to comply with
any valid and legal directive of the Board of Directors or the Chief Executive

Officer; (7) a breach by you of any of your obligations under the Proprietary
Information, Inventions and Non-Solicitation Agreement in the form attached
hereto as Exhibit A (the "PIIN Agreement"); (8) a failure by you to perform
adequately your responsibilities to the Company as demonstrated by objective and
verifiable evidence showing that the business operations under your control have
been materially harmed as a result of your gross negligence or willful
misconduct; or (9) you fail to become a full-time employee on or before
September 8th, 2000. Nothing herein shall be construed to alter the fact that
the Employee is an employee-at-will.

         11. Disability Severance. Notwithstanding the preceding, in the event
that your employment is severed for cause due solely to a disability which
prevents you from being able to perform your duties, the Company will provide
you with up to a maximum of six (6) months salary and guaranteed bonus (paid on
a monthly basis). Disability Severance payments will begin upon the termination
of your disability insurance. These Disability Severance payments will be paid
on a monthly basis for so long as you use your best efforts to secure full time
employment yet remain unemployed. You agree that at this time, you have no
pre-existing conditions which may or might result in your being terminated by
the firm due to any short-term or long-term disability and that you are
currently covered by disability insurance and will remain so throughout the term
of your employment.

         12. Employment Relationship. This Is Not A Contract of Employment.
Notwithstanding any provision of this agreement, either party can terminate
Employee's employment at any time with or without cause. Advance notice by
either party is to be given to the other party according to the following
schedule:

         During the first three (3) months of your employment   None
         After three (3) months of employment                   Thirty (30) days

Provided, however, the Company shall not be required to provide any prior notice
where the Employee's employment is being terminated for "cause."

         13. PINN Agreement. In order to accept this offer of employment, you
must sign a counterpart of this offer letter and execute and deliver the
Proprietary Information, Inventions and Non-Solicitation Agreement in the form
attached hereto as Exhibit A.

action, suit or proceeding arising under or out of this agreement or any of the
transactions or relationships contemplated hereby will be resolved solely in the
state or federal courts located in New York County in the State of New York. We
both hereby submit to the jurisdiction of such court for such purpose.
