                               REGISTER.COM, INC.
                            STOCK ISSUANCE AGREEMENT

            AGREEMENT made this 13th day of August 2002, to be effective as of
May 2nd, 2002 by and between Register.com, Inc., a Delaware corporation, and
Rajiv Samant, a Participant in the Corporation's Amended and Restated 2000 Stock
Incentive Plan.

            All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

      A. PURCHASE OF SHARES

            1. PURCHASE. Participant hereby purchases 34,247 shares of Common
Stock (the "Purchased Shares") pursuant to the provisions of the Stock Issuance
Program at the purchase price of $0.0001 per share (the "Purchase Price").

            2. PAYMENT. Concurrently with the delivery of this Agreement to the
Corporation, Participant shall pay the Purchase Price for the Purchased Shares
in cash or check payable to the Corporation and shall deliver a duly-executed
blank Assignment Separate from Certificate (in the form attached hereto as
Exhibit I) with respect to the Purchased Shares.

            3. STOCKHOLDER RIGHTS. Until such time as the Corporation exercises
the Repurchase Right, Participant (or any successor in interest) shall have all
the rights of a stockholder (including voting, dividend and liquidation rights)
with respect to the Purchased Shares, subject, however, to the transfer
restrictions of this Agreement.

            4. ESCROW. The Corporation shall have the right to hold the
Purchased Shares in escrow until those shares have vested in accordance with the
Vesting Schedule.

            5. COMPLIANCE WITH LAW. Under no circumstances shall shares of
Common Stock or other assets be issued or delivered to Participant pursuant to
the provisions of this Agreement unless, in the opinion of counsel for the
Corporation or its successors, there shall have been compliance with all
applicable requirements of Federal and state securities laws, all applicable
listing requirements of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock is at the time listed for trading and all
other requirements of law or of any regulatory bodies having jurisdiction over
such issuance and delivery.

      B. TRANSFER RESTRICTIONS

            1. RESTRICTION ON TRANSFER. Except for any Permitted Transfer,
Participant shall not transfer, assign, encumber or otherwise dispose of any of
the Purchased Shares which are subject to the Repurchase Right.
<Page>

            2. RESTRICTIVE LEGEND. The stock certificate for the Purchased
Shares shall be endorsed with the following restrictive legend:

                  "The shares represented by this certificate are unvested and
      subject to certain repurchase rights granted to the Corporation and
      accordingly may not be sold, assigned, transferred, encumbered, or in any
      manner disposed of except in conformity with the terms of a written
      agreement dated August 13th, 2002 between the Corporation and the
      registered holder of the shares (or the predecessor in interest to the
      shares). A copy of such agreement is maintained at the Corporation's
      principal corporate offices."

            3. TRANSFEREE OBLIGATIONS. Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to the Repurchase Right to
the same extent such shares would be so subject if retained by Participant.

      C. REPURCHASE RIGHT

            1. GRANT. The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the ninety (90)-day period
following the date Participant ceases for any reason to remain in Service, to
repurchase at the Purchase Price all or any portion of the Purchased Shares in
which Participant is not, at the time of his or her cessation of Service, vested
in accordance with the Vesting Schedule or the provisions of Paragraph C.5 of
this Agreement (such shares to be hereinafter referred to as the "Unvested
Shares").

            2. EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the ninety (90)-day exercise period. The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice. The certificates representing the Unvested Shares
to be repurchased shall be delivered to the Corporation on or before the close
of business on the date specified for the repurchase. Concurrently with the
receipt of such stock certificates, the Corporation shall pay to Owner, in cash
or cash equivalent (including the cancellation of any purchase-money
indebtedness), an amount equal to the Purchase Price previously paid for the
Unvested Shares to be repurchased from Owner.

            3. TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph C.2. In addition, the Repurchase Right shall terminate
and cease to be exercisable with respect to any and all Purchased Shares in
which Participant vests in accordance with the following Vesting Schedule:

      The Participant will vest in 100% of the Purchased Shares on May 2, 2005.

      Vesting will cease on the date of Participant's cessation of Service.

                                       2

            4. RECAPITALIZATION. Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right and any
escrow requirements hereunder, but only to the extent the Purchased Shares are
at the time covered by such right or escrow requirements. Appropriate
adjustments to reflect such distribution shall be made to the number and/or
class of securities subject to this Agreement and to the price per share to be
paid upon the exercise of the Repurchase Right in order to reflect the effect of
any such Recapitalization upon the Corporation's capital structure; PROVIDED,
however, that the aggregate purchase price shall remain the same.

            5. CHANGE IN CONTROL.

                  (a) To the extent the Repurchase Right remains in effect
following a Change in Control, such right shall apply to the new capital stock
or other property (including any cash payments) received in exchange for the
Purchased Shares in consummation of the Change in Control, but only to the
extent the Purchased Shares are at the time covered by such right. Appropriate
adjustments shall be made to the price per share payable upon exercise of the
Repurchase Right to reflect the effect of the Change in Control upon the
Corporation's capital structure; PROVIDED, however, that the aggregate purchase
price shall remain the same. Any capital stock or other property (including cash
payments) issued or distributed with respect to the Purchased Shares may be held
in escrow.

                  (b) The Repurchase Right may also be subject to termination in
whole or in part on an accelerated basis, and the Purchased Shares subject to
immediate vesting, in accordance with the terms of any special Addendum attached
to this Agreement.

      D. SPECIAL TAX ELECTION

            1. SECTION 83(B) ELECTION . Under Code Section 83, the excess of the
fair market value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date. For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Participant may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions. Such election must be filed
with the Internal Revenue Service within thirty (30) days after the date of this
Agreement. Even if the fair market value of the Purchased Shares on the date of
this Agreement equals the Purchase Price paid (and thus no tax is payable), the
election must be made to avoid adverse tax consequences in the future. THE FORM
FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO. PARTICIPANT
UNDERSTANDS THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY
(30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE
FORFEITURE RESTRICTIONS LAPSE.

            2. FILING RESPONSIBILITY. PARTICIPANT ACKNOWLEDGES THAT IT IS
PARTICIPANT'S SOLE RESPONSIBILITY, AND NOT THE

                                       3
<Page>

CORPORATION'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(B), EVEN IF
PARTICIPANT REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING
ON HIS OR HER BEHALF.

      E. GENERAL PROVISIONS

            1. ASSIGNMENT. The Corporation may assign the Repurchase Right to
any person or entity selected by the Board, including (without limitation) one
or more stockholders of the Corporation.

            2. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement or
in the Plan shall confer upon Participant any right to continue in Service for
any period of specific duration or interfere with or otherwise restrict in any
way the rights of the Corporation (or any Parent or Subsidiary employing or
retaining Participant) or of Participant, which rights are hereby expressly
reserved by each, to terminate Participant's Service at any time for any reason,
with or without cause.

            3. NOTICES. Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

            4. NO WAIVER. The failure of the Corporation in any instance to
exercise the Repurchase Right shall not constitute a waiver of any other
repurchase rights that may subsequently arise under the provisions of this
Agreement or any other agreement between the Corporation and Participant. No
waiver of any breach or condition of this Agreement shall be deemed to be a
waiver of any other or subsequent breach or condition, whether of like or
different nature.

            5. CANCELLATION OF SHARES. If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement). Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

            6. PARTICIPANT UNDERTAKING. Participant hereby agrees to take
whatever additional action and execute whatever additional documents the
Corporation may deem necessary or advisable in order to carry out or effect one
or more of the obligations or restrictions imposed on either Participant or the
Purchased Shares pursuant to the provisions of this Agreement.

                                       4

            7. AGREEMENT IS ENTIRE CONTRACT. This Agreement constitutes the
entire contract between the parties hereto with regard to the subject matter
hereof. This Agreement is made pursuant to the provisions of the Plan and shall
in all respects be construed in conformity with the terms of the Plan.

            8. GOVERNING LAW. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York without resort to that
State's conflict-of-laws rules.

            9. SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Participant, Participant's assigns and the legal
representatives, heirs and legatees of Participant's estate, whether or not any
such person shall have become a party to this Agreement and have agreed in
writing to join herein and be bound by the terms hereof.
