                               AMENDMENT NO. 1 TO
                       STRATEGIC AND MARKETING AGREEMENT

     This AMENDMENT NO. 1 (the "Amendment") to the Strategic and Marketing
Agreement is entered into as of this 1st day of October, 2000 (the "Effective
Date"), by and among SBC Communications Inc., a Delaware corporation ("SBC"),
SBC Internet Communications, Inc., a Delaware corporation and an indirect wholly
owned subsidiary of SBC ("SBC Sub"), Prodigy Communications Corporation, a
Delaware corporation ("Prodigy"), and Prodigy Communications Limited
Partnership, a Delaware limited partnership ("Operating Partnership") (each of
SBC, SBC Sub, Prodigy, and Operating Partnership, a "Party" and collectively,
the "Parties").  Capitalized terms used but not defined herein shall have the
meaning assigned to them in the Strategic Agreement (as defined below).

     WHEREAS, the Parties have entered into a Strategic and Marketing Agreement
dated as of November 19, 1999 (the "Strategic Agreement");

     WHEREAS, the Parties each desire to enter into this Amendment for the
purpose of amending the Strategic Agreement;

     WHEREAS, Section 10.6 of the Strategic Agreement permits the Parties to
vary, amend or extend the Strategic Agreement by written agreement executed and
delivered by duly authorized officers or representatives of the respective
Parties; and

     WHEREAS, the Parties each desire that, except to the extent amended by this
Amendment, all terms of the Strategic Agreement shall remain in full force and
effect without amendment, change or modification;

     NOW, THEREFORE, in consideration of the mutual agreements of the Parties
contained herein and in the Strategic Agreement, the Parties hereto agree as
follows:

1.   Deferred Marketing Payments

     1.1.  Deferred Payments. Notwithstanding anything to the contrary contained
           in Section 2.6(e) ("SBC New Subscriber Marketing Payments") of the
           Strategic Agreement, the marketing fees described in Section 2.6(a)
           ("SBC New Subscriber Marketing Payments") of the Strategic Agreement
           (each such fee, a "Bounty") shall be payable by Operating Partnership
           to SBC Sub in three (3) annual payments, each equal to one third of
           the Bounty (each an "Installment"), plus interest on the unpaid
           portion of the Bounty at the Interest Rate (the "Interest", and,
           together with the Installment, a "Payment").
<PAGE>

     1.2.  Interest Rate. The "Interest Rate" shall be the lesser of twelve
           percent (12%) per annum (on the basis of a 360 day year for the
           actual number of days involved) or the maximum rate permitted by New
           York law; provided, however, that if Operating Partnership shall have
           failed to make a scheduled Payment within seven (7) days of such
           Payment coming due, the Interest Rate shall increase to the lesser of
           fifteen percent (15%) per annum or the maximum rate permitted by New
           York law; provided further however, that once Operating Partnership
           shall have paid all Payments in arrears, the Interest Rate shall
           revert to the lesser of twelve percent (12%) per annum or the maximum
           rate permitted by New York law.

     1.3.  Interest Accrual. Interest shall begin to accrue on each Bounty on
           the day following the date on which the Bounty was Earned (as defined
           below) by SBC, its Affiliates or distributors of the Prodigy Service
           pursuant to Section 2.6(a) ("SBC New Subscriber Marketing Payments")
           of the Strategic Agreement. For purposes of Sections 1.2, 1.3, 1.4
           and 1.5 hereof, a Bounty shall be deemed earned ("Earned") on the
           last day of the calendar month in which SBC, its Affiliates or its
           distributors of the Prodigy Service shall have procured a Subscriber
           in accordance with Section 2.6(a) ("SBC New Subscriber Marketing
           Payments") of the Strategic Agreement. For example, SBC shall be
           deemed to have Earned Bounties as of October 31, 2000 for all
           Subscribers procured by SBC, its Affiliates or its distributors of
           the Prodigy Service between October 1, 2000 and October 31, 2000.

     1.4.  Payment Due Date. The first Payment on any Bounty Earned in a fiscal
           year commencing October 1 and ending on September 30 (a "Bounty
           Year") shall be due on the day that is fifteen (15) calendar days
           after the end of such Bounty Year. Subsequent Payments on such
           Bounties are due annually. For example, Operating Partnership must
           make the first Payment for Bounties Earned between October 31, 2000
           and September 30, 2001 (the "Example Bounty Year") no later than
           October 15, 2001. Subsequent Payments on Bounties Earned in the
           Example Bounty Year will be due on October 15, 2002 and October 2003.

     1.5.  Outstanding Bounties. All Bounties Earned prior to October 1, 2000
           and not paid as of the Effective Date, shall have accrued Interest
           as if this Amendment were in effect as of the date that such Bounty
           was Earned. Notwithstanding Section 1.4 hereof, the first Payment on
           all Bounties Earned prior to October 1, 2000 shall be due on
           February 5, 2001.

     1.6.  Waiver of Additional Fees. Notwithstanding Section 2.6(d) ("SBC New
           Subscriber Marketing Payments") of the Strategic Agreement, for the
           term of this Amendment, SBC and SBC Sub agree to waive payment by
           Operating Partnership of any CPE, installation and hardware charges
           (the "Provision Fees") payable pursuant to 2.6(d) ("SBC New
           Subscriber Marketing Payments") of the Strategic Agreement.
           Additionally, SBC and SBC Sub agree to waive payment by
<PAGE>

           Operating Partnership of any such Provision Fees earned but not paid
           by Operating Partnership to SBC Sub prior to the Effective Date.

     1.7.  Prepayment. Nothing contained in this Amendment shall prohibit
           Operating Partnership from making any Payment prior to the date on
           which it is due hereunder.

     1.8.  Offset Right. Notwithstanding anything to the contrary contained in
           Section 2.6(c) ("SBC New Subscriber Marketing Payments") of the
           Strategic Agreement, SBC Sub shall have the right to offset any
           amounts that it may owe to Operating Partnership pursuant to Section
           2.6(c) ("SBC New Subscriber Marketing Payments") of the Strategic
           Agreement against any Payment owed by Operating Partnership to SBC
           Sub.

     1.9.  Termination for Non-Payment. Notwithstanding Section 2.1 hereof, if,
           during the term of the Strategic Agreement, Prodigy fails to make any
           Payment due to SBC or SBC Sub within sixty (60) days of such Payment
           becoming due, SBC may, in its sole discretion, terminate this
           Amendment upon thirty (30) days' written notice to Prodigy and
           Operating Partnership. Upon termination of this Amendment in
           accordance with this Section 1.9, all remaining Payments due under
           this Amendment shall become immediately due and payable.

2.   Term and Termination.

     2.1.  Termination. This Amendment shall terminate upon the termination of
           the Strategic Agreement; provided, that SBC may terminate this
           Amendment in its sole discretion upon sixty (60) days' written notice
           to Prodigy and Operating Partnership given any day that is after the
           date six months after the Effective Date (the "Amendment Termination
           Date"). Upon the termination of this Amendment in accordance with the
           proviso contained in this Section 2.1, all remaining Payments due
           with respect to any Bounty earned prior to the Amendment Termination
           Date shall be due and payable on the day that is 90 days after the
           Amendment Termination Date.

     2.2.  No Effect on Strategic Agreement. Termination of this Amendment
           pursuant to Section 2.1 hereof shall not affect the Strategic
           Agreement, which shall remain in full force and effect without
           amendment, change or modification, except as may otherwise be agreed
           in accordance with the terms of the Strategic Agreement.

3.   Other Rights

     3.1.  Payment Data. Operating Partnership shall provide SBC and SBC Sub
           with all information, data and calculations SBC and SBC Sub may
           request with respect to

           any Payments due to enable SBC and SBC Sub to verify Operating
           Partnership's and Prodigy's compliance with its obligations
           hereunder.

     3.2.  SBC Audit Rights. SBC and SBC Sub or their representatives shall have
           the right to make an inspection of the business, books and records of
           Operating Partnership and Prodigy related to any Payments payable
           under this Amendment and the Strategic Agreement, during normal
           business hours and upon five (5) days' written notice to Operating
           Partnership and Prodigy, that are relevant for the purpose of
           verifying Operating Partnership's and Prodigy's compliance with its
           obligations under this Amendment and the Strategic Agreement.
           Operating Partnership and Prodigy shall maintain business records,
           books, account information, computer logs and related materials that
           are sufficient to permit SBC and SBC Sub to reasonably verify that
           Operating Partnership and Prodigy is in compliance with its
           obligations hereunder.

4.   Miscellaneous.

     4.1.  Each of the Parties hereto represents that this Amendment has been
           duly authorized, executed and delivered by it and constitutes its
           legal, valid and binding obligation, enforceable against it in

           such counterpart being deemed to be an original instrument, and may

        A.  North Queen Street LP, a Massachusetts limited partnership and

Landlord shall complete, or cause to be completed on Landlord's behalf, the work
set forth on Exhibit B hereto (the "Landlord Work") in accordance with plans and
specifications reasonably satisfactory to Tenant. In the event that the Landlord
Work is not so completed, Tenant may, but shall not be obligated to, take such
steps and incur such costs as may be reasonably necessary to complete the
Landlord Work for the account of Landlord, and Landlord shall, within ten days
of demand therefore, reimburse Tenant for any sums paid or costs incurred
therein, failing which Tenant shall have the right to deduct such amount against

cooperate with Shuster in connection with the Landlord Work.

            c.  Landlord hereby consents to the improvements and alterations set

shall be $138,584.25, Monthly Rent for the Premises shall be $11,548.69 and

that it has not dealt, either directly or indirectly, with any broker in
connection with the partial termination set forth in Section 2 above other than
McCall & Almy and Spaulding & Slye Colliers International, to whom Tenant shall
be responsible for the payment of a commission, if any, pursuant to a separate
written agreement.  Landlord and Tenant shall indemnify each other (and Tenant
shall also indemnify Shuster) from and against any and all loss, costs and
expenses, including reasonable attorney's fees, incurred by such indemnified
party, resulting from a breach of the foregoing representation and warranty.

     5.  Definitions.  All capitalized terms used herein shall have the same
meaning as set forth in the Lease unless specifically otherwise provided herein.

     6. Effect of Amendment. Except as set forth herein, the Lease shall remain
unchanged and in full force and effect. All references to the "Lease" shall be
deemed to be references to the Lease as amended by this Second Amendment.
