Subscriber's power and authority and has been duly authorized by all necessary
action (corporate, partnership or otherwise), (b) does not contravene the teens
of such Subscriber's organizational documents or any amendment thereof, and (c)
will not violate, conflict with or result in any breach or contravention of or
the creation of any Lien under any Contractual Obligation of such Subscriber or
any Requirement of Law applicable to such Subscriber.

            6.2 Binding Effect. This Agreement and the other Transaction
Agreements to which such Subscriber is a party have been duly executed and
delivered by such Subscriber, and each constitutes the legal, valid and binding
obligation of such Subscriber enforceable against it in accordance with its

insolvency or other similar laws affecting the enforcement of creditors' rights
generally or by equitable principles relating to enforceability.

                                   ARTICLE 7

                                 INDEMNIFICATION

            7.1 Indemnification. In addition to all other sums due hereunder or
provided for in this Agreement, the Company (the "Indemnifying Party" for
purposes of indemnification under this Section 7.1) agrees to indemnify and hold
harmless each of the Subscribers and their Affiliates and their respective
officers, directors, agents, employees, subsidiaries, partners and controlling
persons (each, an "Indemnified Party" for purposes of indemnification under this
Section 7.1) to the fullest extent permitted by law from and against all losses,
claims, damages, expenses (including, without limitation, reasonable fees,
disbursements and other charges of counsel) or other liabilities (collectively,
"Liabilities") resulting from or arising out of any breach of any representation
or warranty, covenant or agreement of the Indemnifying Party in any Transaction
Agreement, or any legal, administrative or other actions, proceedings or
investigations (whether formal or informal), or written threats thereof, based
upon, relating to or arising out of this Agreement, any other

Transaction Agreement or any transaction contemplated hereby or thereby or any
Indemnified Party's role therein or in any transaction contemplated hereby or
thereby; provided, however, that the Indemnifying Party shall not be liable
under this Section 7.1 to an Indemnified Party (i) for any amount paid in
settlement of claims without the Indemnifying Party's consent (which consent
shall not be unreasonably withheld), (ii) to the extent that it is finally
judicially determined that such Liabilities resulted primarily from the wilful
misconduct or gross negligence of such Indemnified Party, or (iii) to the extent
that it is finally judicially determined that such Liabilities resulted from the
breach by such Indemnified Party of any representation, warranty, covenant or
other agreement of such Indemnified Party contained in any Transaction
Agreement.

            7.2 Notification. Each Indemnified Party under this Article 7 will,
promptly after the receipt of notice of the commencement of any action,
investigation, claim or other proceeding against such Indemnified Party in
respect of which indemnity may be sought from an Indemnifying Party under this
Article 7, notify the Indemnifying Party in writing of the commencement thereof.
The omission of any Indemnified Party to so notify the Indemnifying Party of any
such action shall not relieve the Indemnifying Party from any liability which it
may have to such Indemnified Party (i) other than pursuant to this Article 7 or
(ii) under this Article 7 unless, and only to the extent that, such omission
results in the forfeiture or impairment of substantive rights or defenses. In
case any such action, claim or other proceeding shall be brought against any
Indemnified Party and it shall notify the Indemnifying Party of the commencement
thereof, the Indemnifying Party shall be entitled to assume the defense thereof
at its own expense, with counsel satisfactory to such Indemnified Party in its
reasonable judgment; provided, however, that any Indemnified Party may, at its
own expense, retain separate counsel to participate in such defense.
Notwithstanding the foregoing, in any action, claim or proceeding in which the
Indemnifying Party, on the one hand, and an Indemnified Party, on the other
hand, is, or is reasonably likely to become, a party, such Indemnified Party
shall have the right to employ separate counsel at the Indemnifying Party's
expense and to control its own defense of such action, claim or proceeding if,
in the reasonable opinion of counsel to such Indemnified Party, a conflict or
potential conflict exists between the Indemnifying Party, on the one hand, and
such Indemnified Party, on the other hand, that would make such separate
representation necessary to avoid prejudice to the Indemnified Party.

            7.3 Resolution of Actions. Each Indemnifying Party agrees that it
will not, without the prior written consent of the relevant Indemnified Parties,
settle, compromise or con-sent to the entry of any judgment in any pending or
threatened claim, action or proceeding relating to the matters contemplated by
this Article (if any Indemnified Party is a party thereto or has been actually
threatened to be made a party thereto) unless such settlement, compromise or
consent includes an unconditional release of the Subscribers and each other
Indemnified Party from all liability arising or that may arise out of such
claim, action or proceeding. The rights accorded to Indemnified Parties
hereunder shall be in addition to any rights that any Indemnified Party may have
at common law, by separate agreement or otherwise.

                                   ARTICLE 8

                              AFFIRMATIVE COVENANTS

            8.1 Operation of Company. From and after the date hereof through the
Second Closing Date, the Company shall not enter into arty transaction or take
any action other than in the ordinary course of business, except that the
Company may enter into such transactions and take


                                       9
<PAGE>

such other actions outside of the ordinary course of business if specifically
approved in advance in writing by the Subscribers, or as may be permitted by the
Transaction Agreements.

            8.2 Taxes. The Company shall prepare and timely file, in accordance
with applicable laws and regulations, all Tax returns required to be filed on or
before each Closing Date, and all such Tax returns will be true and complete in
all material respects. The Company shall timely pay all Taxes required to be
paid by them on or before each Closing Date, or that are claimed or asserted by
any taxing authority to be due on or before each Closing Date, except for those
Taxes that are being contested in good faith by appropriate proceedings and with
respect to which adequate reserves have been set aside.

                                   ARTICLE 9

                                  MISCELLANEOUS

            9.1 Obligations of the Subscribers. Each Subscriber's obligation and
the obligations of the Company hereunder are subject to the execution and
delivery of this Agreement by the other Subscriber. The obligations of each
Subscriber shall be several and not joint and no Subscriber shall be liable or
responsible for the acts of the other Subscriber.

            9.2 Termination.

                  (a) This Agreement may be terminated prior to the Second
Closing Date, as to transactions scheduled to take place on the Second Closing
Date, as follows:

                        (i) at the election of the Company if any one or more of
the conditions to its obligation to close has not been fulfilled as of the
Second Closing Date;

                        (ii) at the election of either of the Subscribers if any
one or more of the conditions to their obligation to close has not been
fulfilled as of the Second Closing Date;

                        (iii) at the election of the either of the Subscribers
if the other Subscriber has breached a covenant or agreement contained in this
Agreement, which breach cannot be or is not cured by the Second Closing Date;

                        (iv) at the election of either of the Subscribers if the
Company has breached a covenant or agreement contained in this Agreement, which
breach cannot be or is not cured by the Second Closing Date; or

                        (v) at any time on or prior to the Second Closing Date,
by mutual written consent of the Company and the Subscribers.

            If this Agreement so terminates, it shall become null and void and
have no further force or effect, except as provided in Section 9.2(b).

<PAGE>

                  (b) If this Agreement is terminated in accordance with Section
9.2(a) and any of the transactions contemplated by this Agreement are not
consummated, this Agreement shall become null and void and of no further force
and effect with respect to those transactions not consummated, except for the
provisions of Article 7. Any such termination shall have no effect on
transactions consummated on the First Closing Date, and such consummated
transactions shall continue to be governed by the Transaction Agreements to the
fullest extent possible. None of the parties shall have any liability in respect
of a termination of this Agreement except to the extent that failure to satisfy
any conditions results from the intentional or willful violation by such party
of its obligations contained in this Agreement or any documents delivered
pursuant to this Agreement.

            9.3 Survival of Representations and Warranties. All of the
representations and warranties made herein shall survive the execution and
delivery of this Agreement, any investigation by or on behalf of the

termination of this Agreement and shall remain in full force and effect until
the second anniversary of the Second Closing Date.
