Agreement provides for Merger Sub to be merged (the "Merger") with and into
the Issuer with the Issuer surviving as a wholly-owned subsidiary of TriNet.
Pursuant to and subject to the terms and conditions of the Merger Agreement,
each share of the Issuer's Common Stock issued and outstanding immediately
prior to the effective time of the Merger will be automatically converted
into the right to receive $4.00 in cash (the "Merger Consideration").

 ValueAct Master Fund and ValueAct Master Fund III agreed in the Support
Agreement to, or cause the holder of record on any applicable record date to,
appear at the meeting, in person or by proxy, or otherwise cause all of their
shares of the Issuer's Common Stock to be counted as present thereat for
purposes of establishing a quorum and vote (or caused to be voted), in person
or by proxy, all of their shares of the Issuer?s Common Stock (i) in favor of
the adoption of the Merger, the Merger Agreement and the other transactions
contemplated by the Merger Agreement (and any actions required in furtherance
thereof), (ii) against any action, proposal, transaction or agreement that
would reasonably be expected to result in a breach in any respect of any
covenant, representation or warranty or obligation or agreement of the Issuer
contained in the Merger Agreement or of ValueAct Master Fund or ValueAct
Master Fund III contained in the Support Agreement and (iii) except with the
written consent of TriNet, against the following actions or proposals (other
than the transactions contemplated by the Merger Agreement): (A) any
Acquisition Proposal (as defined in the Merger Agreement); or (B) any other
action or proposal, involving the Issuer or any subsidiary of the Issuer that
would reasonably be expected to prevent or materially impede, interfere with,
delay, postpone or adversely affect the Merger or any other transaction
contemplated by the Merger Agreement. In addition, ValueAct Master Fund and
ValueAct Master Fund III granted to TriNet irrevocable proxies to vote their
shares as described above.

 ValueAct Master Fund and ValueAct Master Fund III also agreed not to
transfer any of their shares of the Issuer's Common Stock during the term of
the Support Agreement, subject to certain exceptions, and not to grant any
proxies or powers of attorney, deposit any shares of the Issuer's Common
Stock into a voting trust, enter into a voting agreement with respect to any
shares or participate directly or indirectly in the solicitation of any
proxies from any person to vote in a manner which would be inconsistent with
