(c) This Waiver constitutes the legal, valid and binding obligations of the
Company, enforceable against it in accordance with its terms.

Agreement are true and correct (except to the extent such representations and

and correct as of such earlier date and except that this subsection (d) shall be

which financial statements have then been delivered in respect of the
representation and warranty made in subsection 6.11(a) of the Credit Agreement
and to take into account any amendments to the Schedules to the Credit Agreement
and other disclosures made in writing by the Company to the Agent and the Banks
after the Closing Date and approved by the Agent and the Required Banks).

(e) The Company is entering into this Waiver on the basis of its own
investigation and for its own reasons, without reliance upon the Agent and the
Banks or any other Person.

(f) The Company's obligations under the Credit Agreement and under the other
Loan Documents are not subject to any defense, counterclaim, set-off, right of
recoupment, abatement or other claim.

4.       Conditions of Effectiveness.
         ---------------------------

(a) The effectiveness of Section 2 of this Waiver shall be subject to the
satisfaction of each of the following conditions precedent:

(1) The Agent shall have received from the Company and the Required Banks a duly
executed original (or, if elected by the Agent, an executed facsimile copy) of
this Waiver.

(2) The Agent shall have received all other documents it or any of the Required
Banks may reasonably request relating to any matters relevant hereto, all in
form and substance satisfactory to the Agent and each such Bank.

(3)      The representations and warranties in Section 3 of this Waiver shall be
true and correct on and as of the date hereof.

(4) The Agent shall have acknowledged a duly executed original counterpart (or,
if elected by the Agent, an executed facsimile copy counterpart) of this Waiver
signed by the Company and the Required Banks.

(b) The Agent shall have received evidence of payment by the Company of all fees
referenced in Section 5 of this Waiver.

(c) For purposes of determining compliance with the conditions specified in this
Section 4, each Bank that has executed this Waiver shall be deemed to have
consented to, approved or accepted, or to be satisfied with, each document or
other matter either sent, or made available for inspection, by the Agent to such
Bank for consent, approval, acceptance or satisfaction, or required thereunder
to be consented to or approved by or acceptable or satisfactory to such Bank.

(d) Except as expressly waived pursuant hereto, the Credit Agreement and the
other Loan Documents shall remain unchanged and in full force and effect and are
hereby ratified and confirmed in all respects.

(e)      The Agent will notify the Company and the Banks of the effectiveness of
this Waiver.

5. Fees. Contingent upon the satisfaction of the conditions precedent set forth

this Waiver on or prior to the date hereof a fee equal to 0.10% of the
Commitment of such Bank.

6.       Miscellaneous.
         --------------

(a) The Company acknowledges and agrees that the execution and delivery by the
Agent and the Required Banks of this Waiver shall not be deemed to create a
course of dealing or an obligation to execute similar waivers or amendments
under the same or similar circumstances in the future.

(b) This Waiver shall be binding upon and inure to the benefit of the parties
hereto and to the Credit Agreement and their respective successors and assigns.

(c) This Waiver shall be governed by and construed in accordance with the law of
the State of California, provided that the Agent and the Banks shall retain all
rights arising under Federal law.

(d) This Waiver may be executed in any number of counterparts, each of which
shall be deemed an original, but all such counterparts together shall constitute
but one and the same instrument. Each of the parties hereto understands and
agrees that this document (and any other document required herein) may be
delivered by any party thereto either in the form of an executed original or an
executed original sent by facsimile transmission to be followed promptly by
mailing of a hard copy original, and that receipt by the Agent of a facsimile
transmitted document purportedly bearing the signature of a Bank or the Company
shall bind such Bank or the Company, respectively, with the same force and
effect as the delivery of a hard copy original. Any failure by the Agent to
receive the hard copy executed original of such document shall not diminish the
binding effect of receipt of the facsimile transmitted executed original of such
document of the party whose hard copy page was not received by the Agent.

(e) This Waiver contains the entire and exclusive agreement of the parties
hereto with reference to the matters discussed herein. This Waiver supersedes
all prior drafts and communications with respect hereto. This Waiver may not be
amended except in accordance with the provisions of Section 11.1 of the Credit
Agreement.

(f) If any term or provision of this Waiver shall be deemed prohibited by or
invalid under any applicable law, such provision shall be invalidated without
affecting the remaining provisions of this Waiver, the Credit Agreement or the
other Loan Documents.

(g) The Company agrees to pay or reimburse BofA (including in its capacity as
Agent), upon demand, for all reasonable costs and expenses (including reasonable
Attorney Costs) incurred by BofA (including in its capacity as Agent) in
connection with the development, preparation, negotiation, execution and
delivery of this Waiver.

(h) This Waiver shall constitute a "Loan Document" under and for all purposes of
the Credit Agreement and the other Loan Documents.

                              [Signatures follow.]






                  IN WITNESS WHEREOF, the parties hereto have caused this Waiver
to be duly executed and delivered in San Francisco, California by their proper
and duly authorized officers as of the day and year first above written.
