     This Amendment No. 2 amends and supplements the Tender Offer Statement on
Schedule TO-T filed with the Securities and Exchange Commission on November 21,
2001 (as previously amended and amended hereby, the "Schedule TO") by
Information Holdings Inc., a Delaware corporation ("Parent"), and Fluid
Acquisition Corp., a Delaware corporation ("Purchaser") and a wholly owned
subsidiary of Parent, and amended by Amendment No. 1 filed on December 7, 2001,
with respect to the offer by Purchaser to purchase all outstanding shares of
common stock, par value $0.001 per share (the "Shares"), of Liquent, Inc.
(formerly known as ESPS, Inc.), a Delaware corporation, at a purchase price of
$2.27 per Share, net to the seller in cash, upon the terms and subject to the
conditions set forth in the Offer to Purchase and in the related Letter of
Transmittal. Capitalized terms used and not defined herein have the meanings
given to them in the Offer to Purchase and the Schedule TO.

     The Statement is also a Statement on Schedule 13D of Parent and Purchaser.
This Amendment No. 2 also constitutes Amendment No. 1 to such Schedule 13D.

ITEM 6. INTEREST IN SECURITIES OF THE SUBJECT COMPANY.

     The information set forth in Item 6 of the Statement is hereby amended and
supplemented by amending and supplementing "Section 9-Certain Information
Concerning Purchaser and Parent" of the Offer to Purchase as follows:

          The Offer expired at 12:00 Midnight, New York City time, on Wednesday,
          December 19, 2001. Based on information provided by the Depositary,
          16,839,161 Shares or 92% of the outstanding Shares were validly
          tendered and not withdrawn pursuant to the Offer (including 5,942,981
          Shares tendered by means of guaranteed delivery) at the expiration of
          the Offer. Purchaser has accepted for payment, and has notified the
          Depositary to promptly pay for the tendered and accepted Shares, in
          accordance with the Offer. On December 20, 2001, Parent issued a press
          release, a copy of which is attached hereto as Exhibit (a)(9) and
          incorporated herein by reference.

          Parent and Purchaser intend to complete the acquisition of the
          remaining Shares by promptly merging Purchaser with and into the
          Company in accordance with Delaware's merger provisions.
