This Amendment No. 1 amends and supplements the tender offer Statement on
Schedule TO originally filed with the Securities and Exchange Commission on
November 15, 2004 (the "Schedule TO") relating to the issuer tender offer of
MemberWorks Incorporated, a Delaware corporation ("MemberWorks"), to purchase up
to 500,000 shares of its common stock, $0.01 par value per share. When the
Schedule TO was filed on November 15, 2004, the Company's name was MemberWorks
Incorporated. The tender offer was also commenced on this date. On November 18,
2004, upon shareholder approval, the Company changed its name to Vertrue
Incorporated. Therefore, all references in this Amendment No. 1, the attached
Offer to Purchase, Letter of Transmittal, the Direction Forms to Participants in
the MemberWorks Incorporated 401(k) Profit Sharing Plan and Employee Stock
Purchase Plan and all related documents to "the Company", "MemberWorks", "we" or
"us" refer to Vertrue Incorporated. The Company is offering to purchase these
shares at a price not greater than $35.00 nor less than $30.00 per share, net to
the seller in cash, without interest, upon the terms and subject to the
conditions set forth in the Offer to Purchase, dated November 15, 2004, (the
"Offer to Purchase"), and in the related Letter of Transmittal, which, as
amended or supplemented from time to time, together constitute the tender offer.
This tender offer Statement on Schedule TO is intended to satisfy the reporting
requirements of Rule 13e-4(c)(1) of the Securities Exchange Act of 1934, as
amended.

The information in the Offer to Purchase and related Letter of Transmittal
originally filed as Exhibits (a)(1)(i) and (a)(1)(ii) respectively, to the
Schedule TO and the Direction Forms to Participants in the MemberWorks
Incorporated 401(k) Profit Sharing Plan and Employee Stock Purchase Plan
originally filed as Exhibits (a)(1)(vi) and (a)(1)(vii) respectively, to the
Schedule TO are hereby amended to the extent specifically provided herein, such
amendments being incorporated herein by reference in response to Items 1-11 of
this Amendment No. 1 and are filed as Exhibits (a)(1)(i), (a)(1)(ii), (a)(1)(vi)
and (a)(1)(vii). This Amendment No. 1 is filed to incorporate revisions made to
the Offer to Purchase, Letter of Transmittal and the Direction Forms to
Participants in the MemberWorks Incorporated 401(k) Profit Sharing Plan and
Employee Stock Purchase Plan.
