     This Amendment No. 1 amends and supplements the Solicitation/Recommendation
Statement on Schedule 14D-9, originally filed with the Securities and Exchange
Commission on December 23, 1999 (the "Schedule 14D-9" by EIS International,
Inc., a Delaware corporation (the "Company"). The Schedule 14D-9 was filed in
connection with the tender offer made by SERSys Acquisition Corporation
("Purchaser"), a Delaware corporation and a wholly owned subsidiary of SER
(USA), Inc., a Delaware corporation that is a wholly owned subsidiary of SER
Systeme AG, a German corporation ("Parent"), to purchase all of the outstanding
shares of common stock, par value $0.01 per share (the "Common Stock") and their
associated rights (the "Rights") to purchase Series A Preferred Stock, par value
$0.01, pursuant to that certain Rights Agreement, dated as of May 16, 1997
between Company and BankBoston N.A., as amended, (the "Rights Agreement") (such
Rights, together with the Common Stock, are collectively referred to herein as
the "Shares"), at a purchase price of $6.25 per Share, net to the seller in
cash, without interest thereon, upon the terms and subject to the conditions set
forth in the Offer to Purchase dated December 23, 1999, and in the related
Letter of Transmittal, each as previously submitted to the holders of the
Company's Shares (the Offer to Purchase and the Letter of Transmittal, as may be
amended from time to time, constitute the "Offer"). Copies of the Offer to
Purchase and Letter of Transmittal are attached as Exhibit (a)(1) and (a)(2) to
the Schedule 14D-9. The Offer is being made pursuant to an Agreement and Plan of
Merger dated as of December 17, 1999 (the "Merger Agreement") by and among
Parent, Purchaser and the Company.

ITEM 4.  THE SOLICITATION OR RECOMMENDATION

     Item 4 is hereby amended and supplemented by the addition of the following
information thereto:

     The fairness opinion (the "Fairness Opinion") of the Company's financial
advisor, Updata Capital, Inc. ("Updata") is addressed solely to the Company's
Board of Directors (the "Company Board") for the use of such directors in their
capacity as members of the Company Board in connection with their review and
evaluation of the Offer and Merger. The Fairness Opinion may not be relied upon
by any person other than the directors in their capacity as members of the
Company Board without the prior written consent of Updata. Accordingly, under
the terms of the Fairness Opinion, no Company stockholder may rely or allege any
reliance on Updata's Fairness Opinion or analysis in connection with the
stockholder's consideration of the merits of the Offer or Merger or otherwise.
It is Updata's position that its duties in connection with the Fairness Opinion
are solely to the Company Board, and that it has no legal responsibility to any
other persons, including the Company's stockholders. Updata would likely assert
the substance of this disclaimer as a defense to claims, if any, that might be
brought against it by a Company stockholder with respect to the Fairness
Opinion. However, Updata is not aware of any definitive court ruling on the
availability to a financial advisor of this defense to stockholder liability
with respect to a fairness opinion. That issue would need to be resolved by a
court of competent jurisdiction. In any event, the availability or
non-availability of this defense will have no effect on Updata's rights,
responsibilities or liabilities under the federal securities laws, or the rights
and responsibilities of the Company Board under the Delaware General Corporation
Law or under the federal securities laws. Updata has consented to the
reproduction of the Fairness Opinion as an Exhibit to the Schedule 14D-9.
