may be bound; or (d) any order, judgment, writ, injunction, decree, license,
franchise, permit or other authorization of any Governmental Authority by which

a Material Adverse Effect on such Investor or materially impair the ability of
such Investor to consummate the transactions contemplated hereby.

         4.5     THIRD-PARTY AND GOVERNMENTAL CONSENTS. Except as previously
obtained, no approval, consent, waiver, order or authorization of, or
registration, qualification, declaration, or filing with, or notice to, any
Governmental Authority or other third party is required on the part of such
Investor in connection with the execution and delivery of this Agreement by
such Investor or the consummation of the transactions contemplated hereby or
thereby.

         4.6     ACCREDITED INVESTORS.

         (a)     Such Investor is acquiring the Special Warrants to be acquired
by it under this Agreement (including, for purposes of this representation and
warranty, the shares of Common Stock underlying such Special Warrants)
(collectively, the "Securities") for its own account, for investment purposes,
and not with a view to, or for resale in connection with, any public
distribution of the Securities in violation of the federal securities laws.

         (b)     Such Investor understands that the Securities have not been
registered under the Securities Act or any federal or state law by reason of
specific exemptions under the provisions thereof, the availability of which
depend in part upon the accuracy of its representations made in this Section
4.6.

         (c)     Such Investor understands that the Company is relying upon the
representations and agreements contained in this Section 4.6 for the purpose of
determining whether this transaction meets the requirements for such exemptions.

         (d)     Such Investor is an "accredited investor" as defined in Rule
01(a) of Regulation D under the Securities Act.

         (e)     Such Investor has such knowledge, skill and experience in
business, financial and investment matters that it is capable of evaluating the
merits and risks of an investment in the Securities. The undersigned recognizes
that an investment in the Securities is a speculative investment involving a
high degree of risk.

         (f)     Such Investor understands that the Securities are "restricted
securities" under applicable federal securities laws and that the Securities
Act and the rules of the Securities and Exchange Commission thereunder provide
in substance that it may dispose of the Securities only pursuant to an
effective registration statement under the Securities Act or an exemption
therefrom, and it understands that, notwithstanding the Registration Statement
provided to such Investor by the Company, the Company has no obligation to
register any of the Securities or securities issuable upon conversion or
exercise thereof, thereunder, except as contemplated by the Stockholders
Agreement and Amendment No. 2 to the Stockholders Agreement.

         (g)     Such Investor has been furnished by the Company all
information (or provided access to all information) regarding the business and
financial condition of the Company, its expected plans for future business
activities, the attributes of the Securities and the merits and risks of an


                                       8
<PAGE>

investment in the Securities that it has requested or otherwise needs to
evaluate the investment in the Securities.

         (h)     Such Investor is not purchasing the Securities as a result of
any form of general solicitation or general advertising.

                             ADDITIONAL AGREEMENTS

         5.1     CONFIDENTIALITY. Each party hereto shall hold and shall cause
its employees, auditors, attorneys, financial advisors, bankers and other
consultants to hold in strict confidence, unless compelled to disclose by
judicial or administrative process or by other requirements of Law, all
confidential or proprietary documents and information concerning any other
party furnished to it by such other party or its representatives in connection
with the transactions contemplated by this Agreement (except to the extent that
such information can be shown to have been (a) previously known by the party to
which it was furnished other than as a result of the evaluation or negotiation
of the transactions contemplated by this Agreement, or (b) in the public domain
through no fault of such party), and each party shall treat such information as
the sole property of the party furnishing the information and it shall not
release or disclose such information to any other person, except its employees,
auditors, attorneys, financial advisors, bankers and other consultants and
advisors in connection with this Agreement who agree to be bound by the
forgoing. If the transactions contemplated by this Agreement are not
consummated, such confidence shall be maintained except to the extent such
information comes into the public domain through no fault of the party required
to hold it in confidence, and such information shall not be used to the
detriment of, or in relation to any investment in, the other party, and all
such documents (including copies thereof) shall be destroyed or returned to the
other party. Each party shall be deemed to have satisfied its obligation to
hold confidential, proprietary or other information concerning or supplied by
the other parties if it exercises the same care as it takes to preserve
confidentiality for its own similar information.

         5.2     FURTHER ASSURANCES. Each party hereto, upon the request of any
other party hereto, shall do all such further acts and execute, acknowledge and
deliver all such further instruments and documents as may be necessary or
desirable to carry out the transactions contemplated by this Agreement.

         5.3     EXPENSES. All costs and expenses incurred in connection with
the transactions contemplated by this Agreement shall be paid by the party
incurring such cost or expense, provided that, within 60 days after the
Closing, the Company shall reimburse each of (i) the DLJMB Investors, (ii)
CalPERS, (iii) OTP and (iv) LJM2 for all reasonable documented out of pocket
expenses (including legal fees and expenses) incurred in connection with the
transactions contemplated by this Agreement, up to a maximum of $20,000 for
each of (i) the DLJMB Investors, (ii) CalPERS, (iii) OTP and (iv) LJM2.

                                INDEMNIFICATION

         7.1     SURVIVAL

         (a)     All of the representations and warranties of the Company and
the Investors shall survive the date hereof and continue in full force and
effect for a period of two (2) years thereafter, after which they shall
terminate and be of no further force or effect; provided that the
representations set forth in Sections 3.1 and 4.1 shall survive the date hereof
for the applicable statute of limitations.

         (b)     All of the covenants of the parties hereto that are intended
to be performed after the date hereof shall survive the date hereof.

         7.2     THE COMPANY'S AGREEMENT TO INDEMNIFY. Subject to the terms and
conditions of this Article VII, the Company hereby agrees to indemnify, defend
and hold harmless the Investors, from and against all demands, claims, actions
or causes of action, assessments, losses, damages, liabilities, costs and
expenses, including, without limitation, interest, penalties and attorney's
fees and expenses (collectively, "Damages"), asserted against, resulting to,
imposed upon or incurred by the Investors, directly or indirectly, by reason of
or resulting from any breach of any representation, warranty or agreement of
the Company contained in or made pursuant to this Agreement, provided that, in
the case of a breach of a representation or warranty, a written claim for
indemnification against the Company is given pursuant to Section 8.3 below
within the survival period set forth in Section 7.1(a).

         7.3     INVESTORS' AGREEMENT TO INDEMNIFY. Subject to the terms and
conditions of this Article VII, each Investor, severally and not jointly,
hereby agrees to indemnify, defend and hold harmless the Company from and
against any and all Damages asserted against, resulting to, imposed upon or
incurred by the Company, directly or indirectly, by reason of or resulting from
a breach of any representation, warranty or agreement of such Investor
contained in or made pursuant to this Agreement, provided that, in the case of
a breach of a representation or warranty, a written claim for indemnification
against the Investors is given pursuant to Section 8.3 below within the
survival period set forth in Section 7.1(a).

         7.4     MATTERS INVOLVING THIRD PARTIES. If any third party shall
notify any party hereto (the "Indemnified Party") with respect to any matter
which may give rise to a claim for


                                      11
<PAGE>

indemnification against any other party hereto (the "Indemnifying Party") under
this Article VII, then the Indemnified Party shall notify each Indemnifying
Party thereof promptly; PROVIDED, HOWEVER, that no delay on the part of the
Indemnified Party in notifying any Indemnifying Party shall relieve the
Indemnifying Party from any liability or obligation hereunder unless (and then
solely to the extent) the Indemnifying Party thereby is prejudiced as a result
of such delay. In the event any Indemnifying Party notifies the Indemnified
Party within thirty (30) days after the Indemnified Party has given notice of
the matter that the Indemnifying Party is assuming the defense thereof, (A) the
Indemnifying Party will defend the Indemnified Party against the matter with
counsel of its choice reasonably satisfactory to the Indemnified Party, (B) the
Indemnified Party may retain separate co-counsel at its sole cost and expense
(except that the Indemnifying Party will be responsible for the fees and
expenses of the separate co-counsel to the extent the Indemnified Party has
been advised by counsel that (i) the counsel the Indemnifying Party has
selected has a conflict of interest or (ii) there may be one or more legal
defenses available to the Indemnified Party that are different from or
additional to those available to the Indemnifying Party), (C) the Indemnified
Party will not consent to the entry of any judgment or enter into any
settlement with respect to the matter without the written consent of the
Indemnifying Party (not to be withheld unreasonably), and (D) the Indemnifying
Party will not consent to the entry of any judgment with respect to the matter,
or enter into any settlement which does not include a provision whereby the
plaintiff or claimant in the matter releases the Indemnified Party from all
liability with respect thereto, without the written consent of the Indemnified
Party (not to be withheld unreasonably). In the event no Indemnifying Party
notifies the Indemnified Party within thirty (30) days after the Indemnified
Party has given notice of the matter that the Indemnifying Party is assuming
the defense thereof, however, the Indemnified Party may defend against, or
enter into any settlement with respect to, the matter in any manner it
reasonably may deem appropriate. At any time after commencement of any such
action, any Indemnifying Party may request an Indemnified Party to accept a
bona fide offer from the other parties to the action for a monetary settlement
payable solely by such Indemnifying Party (which does not burden or restrict
the Indemnified Party nor otherwise prejudice it) whereupon such action shall
be taken unless the Indemnified Party determines that the dispute should be
continued, in which case the Indemnifying Party shall be liable for indemnity
hereunder only to the extent of the lesser of (i) the amount of the settlement
offer or (ii) the amount for which the Indemnified Party may be liable with
respect to such action. In addition, the party controlling the defense of any
third party claim shall deliver, or cause to be delivered, to the other party
copies of all correspondence, pleadings, motions, briefs, appeals or other
written statements relating to or submitted in connection with the defense of
the third party claim, and timely notices of, and the right to participate in
(as an observer) any hearing or other court proceeding relating to the third
party claim.

         7.5     EXCLUSIVE REMEDY; LIMITATION ON DAMAGES

         (a)     NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY AND EXCEPT AS
PROVIDED IN THE PROVISO CLAUSE TO THIS SENTENCE AND IN SECTION 8.8, IN
CONNECTION WITH ANY CLAIM MADE BY A PARTY AGAINST ANOTHER PARTY HEREUNDER, THE
CLAIMING PARTY SHALL NOT BE ENTITLED TO RECOVER


                                      12
<PAGE>

ANY PUNITIVE, CONSEQUENTIAL, SPECIAL, INCIDENTAL OR INDIRECT DAMAGES
(INCLUDING, WITHOUT LIMITATION, ANY EXEMPLARY DAMAGES, TREBLE DAMAGES,
PENALTIES, OR LOSS OF PROFITS OR INCOME), WHETHER BASED ON STATUTE, IN TORT,
CONTRACT OR OTHERWISE, REGARDLESS OF WHETHER SUCH DAMAGES MAY BE AVAILABLE
UNDER APPLICABLE LAW OR OTHERWISE, AND WHETHER OR NOT ARISING FROM A PARTY'S
SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT, THE
PARTIES HERETO HEREBY WAIVING THEIR RIGHT, IF ANY, TO RECOVER SUCH DAMAGES IN
CONNECTION WITH ANY CLAIMS HEREUNDER; PROVIDED, HOWEVER, THAT (A) IN NO EVENT
SHALL SUCH LIMITATIONS OR RESTRICTIONS PREVENT A PARTY FROM RECOVERING ITS
ACTUAL DAMAGES AND (B) THE FOREGOING LIMITATIONS AND RESTRICTIONS SHALL NOT
APPLY TO ANY SUCH DAMAGES THAT ARE ATTRIBUTABLE TO THE GROSS NEGLIGENCE,
WILLFUL MISCONDUCT OR FRAUD OF THE PARTY AGAINST WHOM SUCH CLAIM IS MADE.

         (b)     THE COMPANY AND THE INVESTORS AGREE THAT THEIR SOLE RESPECTIVE
RIGHTS FOR ANY RECOURSE OF ANY KIND WITH RESPECT TO ANY BREACHES OF ANY
REPRESENTATIONS, WARRANTIES OR COVENANTS UNDER THIS AGREEMENT SHALL BE THEIR
RESPECTIVE RIGHTS TO INDEMNIFICATION AS EXPRESSLY SET FORTH IN THIS ARTICLE VII.

         7.6     EXPRESS NEGLIGENCE CLAUSE. THE PARTIES HERETO INTEND THAT THE
INDEMNITIES SET FORTH IN THIS ARTICLE VII BE CONSTRUED AND APPLIED AS WRITTEN
ABOVE NOTWITHSTANDING ANY RULE OF CONSTRUCTION TO THE CONTRARY. WITHOUT
LIMITING THE FOREGOING, THE INDEMNITIES SHALL APPLY NOTWITHSTANDING ANY STATE'S
"EXPRESS NEGLIGENCE RULE" OR SIMILAR RULE THAT WOULD DENY COVERAGE BASED ON AN
INDEMNITEE'S SOLE, CONCURRENT OR CONTRIBUTORY ACTIVE OR PASSIVE NEGLIGENCE OR
GROSS NEGLIGENCE OR STRICT LIABILITY. IT IS THE INTENT OF THE PARTIES THAT, TO
THE EXTENT PROVIDED IN THIS ARTICLE VI, THE INDEMNITIES SET FORTH HEREIN SHALL
APPLY TO AN INDEMNITEE'S SOLE, CONCURRENT OR CONTRIBUTORY ACTIVE OR PASSIVE
NEGLIGENCE, GROSS NEGLIGENCE OR STRICT LIABILITY. THE PARTIES AGREE THAT THIS
PROVISION IS "CONSPICUOUS" FOR PURPOSES OF ALL STATE LAWS.


                                  ARTICLE VIII
                               GENERAL PROVISIONS

         8.1     ENTIRE AGREEMENT; TERMINATION OF PRIOR AGREEMENT. This
Agreement (including the exhibits and schedules) contains the entire agreement
among the parties with respect to the subject matter hereof and the related
transactions and supersedes all prior agreements, written or oral, with respect
thereto.

         8.2     WAIVERS AND AMENDMENTS. This Agreement may be amended,
superseded, canceled, renewed or extended only by a written instrument signed
by the parties hereto. The


                                      13
<PAGE>

provisions hereof may be waived in writing by the parties hereto. No delay on
the part of any party in exercising any right, power or privilege hereunder
shall operate as a waiver thereof, nor shall any waiver on the part of any
party of any such right, power or privilege, nor any single or partial exercise
of any such right, power or privilege, preclude any further exercise thereof or
the exercise of any other such right, power or privilege.

         8.3     NOTICES.
