         This Amendment No. 3 amends and supplements the Tender Offer Statement,
as amended, on Schedule TO ("Schedule TO") filed with the Securities and
Exchange Commission on June 11, 2002, relating to a tender offer by Kingfish
Acquisition Corporation, a Delaware corporation (the "Purchaser") and a
wholly-owned subsidiary of Tier Technologies, Inc., a California corporation
("Parent"), to purchase all of the outstanding shares of common stock, par value
$0.01 per share (the "Shares"), of Official Payments Corporation, a Delaware
corporation (the "Company"), at a price of $3.00 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 June 11, 2002 and in the related Letter of
Transmittal (which, together with any supplements or amendments, collectively
constitute the "Offer"). Capitalized terms used and not otherwise defined shall
have the meanings assigned to such terms in the Offer to Purchase.

Item 11. Additional Information

         (a)(5) On June 19, 2002, a purported class action complaint was filed
in the Delaware Court of Chancery against the Company, each of the Company's
directors, Parent and Purchaser (the "Complaint"). The Complaint purports to
assert claims on behalf of all public stockholders of the Company. The Complaint
alleges, among other things, that (i) the individual defendants breached a
fiduciary duty of disclosure by failing to disclose certain allegedly material
information in publicly-filed documents and (ii) Parent and Purchaser are acting
in violation of Section 203 of Delaware General Corporations Law by purportedly
failing to obtain the approval of the Company's board of directors before
becoming an "interested stockholder" (as that term is defined under Section
203) of the Company. The Complaint seeks, among other things, (1) certification
of this action as a class action, plaintiff as the class representative and the
attorneys as class counsel; (2) to enjoin the Offer; (3) an award of recissory
and/or monetary damages; and (4) such other relief as the Court deems equitable
and just, including attorneys' fees and costs.

         The foregoing summary of the Complaint is qualified in its entirety by
reference to the Complaint, a copy of which is filed as Exhibit (a)(5)(C) hereto
and incorporated by reference herein.

         On June 26, 2002, the parties to the Complaint entered into a
Memorandum of Understanding with respect to a proposed settlement of the
purported stockholder class action stockholder. The Memorandum of Understanding
provides for certain additional disclosure set forth in the Company's Amendment
No. 1 to the Schedule 14D-9 to be filed with the SEC and for full releases of
the defendants and certain related or affiliated persons and extinguishes all
claims that have been, could have been or could be asserted by or on behalf of
any member of the class against the defendants and/or any related or affiliated
persons which in any manner relate to the allegations, facts or other matters
raised in the lawsuits or which otherwise relate to the transactions
contemplated by the Merger Agreement, including the Offer and the Merger. The
Memorandum of Understanding provides for the payment of up to $175,000 of fees
and expenses for the plaintiff's counsel upon final approval of the settlement
of the actions. The final settlement of the Complaint, including the amount of
attorneys' fees to be paid, is subject to court approval and there can be no
assurance that such approval will be obtained.

         The defendants to the lawsuits have denied that they have engaged in
any wrongdoing whatsoever, and have agreed to the Memorandum of Understanding to
eliminate the burden and expense of further litigation and to permit the Offer
and Merger to proceed as scheduled.

         The foregoing summary of the Memorandum of Understanding is qualified
in its entirety by reference to the Memorandum of Understanding, a copy of which
is filed as Exhibit (a)(5)(D) hereto and is incorporated herein by reference.
