respective business as now being conducted and (ii) duly qualified to do

Purchaser's ability to perform its obligations hereunder.

     3.2  Due Authorization. The Purchaser has all right, power and authority to
enter into this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement by the Purchaser and the
consummation by the Purchaser of the transactions contemplated hereby have been
duly authorized by all necessary action on behalf of the Purchaser. This
Agreement has been duly executed and delivered by the Purchaser and constitutes

     3.3  Conflicting Agreements and Other Matters. Neither the execution and
delivery of this Agreement nor the performance by the Purchaser of its
obligations hereunder will, in any material manner, conflict with, result in a

     9.9  Expenses and Remedies.

          (a)  Irrespective of whether the Closing is effected, each party to

the negotiation, execution, delivery and performance of this Agreement and any
of the other documents associated with the consummation of the transactions
contemplated herein. If any action at law or in equity is necessary to enforce
or interpret the terms of this Agreement, the Investor's Rights Agreement or the
Certificate of Designation, the prevailing party shall be entitled to reasonable
attorney's fees, costs and necessary disbursements in addition to any other
relief to which such party may be entitled.

          (b)  The Company further agrees to indemnify and hold harmless the
Purchaser and the Purchaser's officers, directors, partners, employees, trustees
and agents, each Person who controls the Purchaser within the meaning of the
Securities Act or the Exchange Act, from and against any and all costs,
expenses, damages or other liabilities resulting from any breach of this
Agreement by the Company, including any legal, administrative or other
proceedings arising out of such breach (other than such costs, expenses, damages
or other liabilities resulting, directly or indirectly, from (i) the breach by
the Purchaser of any of its representations, warranties or other agreements
contained herein, (ii) the gross negligence or willful misconduct of the
Purchaser or any of its officers, directors, partners, employees or agents, or
any Person who controls the Purchaser within the meaning of the Securities Act
or the Exchange Act or (iii) an ERISA violation resulting from any action or
inaction by the Purchaser, other than an ERISA violation resulting from a breach
by the Company of this Agreement); provided, however, that, if and to the extent
that such indemnification is unenforceable for any reason, the Company shall
make

                                       15
<PAGE>

the maximum contribution to the payment and satisfaction of such indemnified
liability which shall be permissible under applicable laws.

          (c)  The indemnified party under this Section 9.9 will, promptly after
the receipt of notice of the commencement of any action against such indemnified
party in respect of which indemnity may be sought from the Company on account of
an indemnity agreement contained in this Section 9.9 notify the Company in
writing of the commencement thereof. The omission of any indemnified party so to
notify the Company of any such action shall not relieve the Company from any
liability which it may have to such indemnified party except to the extent the
Company shall have been prejudiced by the omission of such indemnified party so
to notify the Company, pursuant to this Section 9.9. In case any such action
shall be brought against any indemnified party and it shall notify the Company
of the commencement thereof, the Company shall be entitled to participate
therein and, to the extent that it may wish, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the Company to such indemnified party of its election so to assume the defense
thereof, the Company will not be liable to such indemnified party under this
Section 9.9 for any legal or other expense subsequently incurred by such
indemnified party in connection with the defense thereof nor for any settlement
thereof entered into without the consent of the Company; provided, however, that
(i) if the Company shall elect not to assume the defense of such claim or action
or (ii) if the indemnified party reasonably determines (x) that there may be a
conflict between the positions of the Company and of the indemnified party in
defending such claim or action or (y) that there may be legal defenses available
to such indemnified party different from or in addition to those available to
the Company, then separate counsel for the indemnified party shall be entitled
to participate in and conduct the defense, in the case of (i) and (ii) (x), or
such different defenses, in the case of (ii)(y), and the Company shall be liable
for any reasonable legal or other expenses incurred by the indemnified party in
connection with any such defenses. The obligations of the Company to each
indemnified party hereunder shall be separate obligations, and the Company's
liability to any such indemnified party hereunder shall not be extinguished
solely because any other indemnified party is not entitled to indemnity
