in full force and effect.  The Company has no reason to believe that any of the
Licenses will be revoked, canceled, rescinded, or not renewed in the ordinary
course and on the same or more favorable material terms, other than any such
revocation, cancellation, rescission, or non-renewal of any License which is not

the business or operations of the Company and the Subsidiaries taken as whole.
There is not now pending any material complaint nor, to the knowledge of the

is operating in all material respects in accordance with the terms of the

is engaged, in amounts which are customarily considered adequate in relation to
the business and properties of such Company Party, and all premiums to date have
been paid in full.  No Company Party has been refused any insurance, nor has its
coverage been limited, by an

                                       29

insurance carrier to which it has applied for insurance or with which it has

part of the Indemnified Party in notifying any Indemnifying Party shall relieve
the Indemnifying Party from any obligation hereunder unless (and then solely to
the extent) the Indemnifying Party thereby is prejudiced; it being understood

Indemnifying Party prior to settling a Third Party Claim (whether by paying a
claim or executing a binding settlement agreement with respect thereto) or the

against the entirety of any Adverse Consequences the Indemnified Party may
suffer resulting from, arising out of, relating to, in the nature of, or caused
by the Third Party Claim (it being understood by the Parties that the
Indemnified Party may take such actions as are reasonable in connection with its
defense until it receives such notice from the Indemnifying Party), and (ii) the
Indemnifying Party conducts the defense of the Third Party Claim actively and
diligently.

     (c)  So long as the Indemnifying Party is conducting the defense of the
Third Party Claim in accordance with Section 6.4(b) above, (i) the Indemnified
                                     --------------
Party may retain separate co-counsel at its sole cost and expense and
participate in the defense of the Third Party Claim (provided that the
Indemnified Party will have the right to employ separate counsel to represent
the Indemnified Party (the fees and expenses of which will be borne by the
Indemnifying Party if, in the Indemnified Party's reasonable judgment, a
conflict of interest between the Indemnified Party and the Indemnifying Party
exists with respect to such claim), (ii) the Indemnified Party will not consent
to the entry of any judgment or enter into any settlement with respect to the
Third Party Claim without the prior written consent of the Indemnifying Party
(not to be withheld unreasonably), and (iii) the Indemnifying Party will not,
without the prior written consent of the Indemnified Party (not to be withheld
unreasonably), consent to the entry of any judgment or enter into any settlement
with respect to the Third Party Claim in which any relief other than the payment
of money damages is sought against any Indemnified Party, unless such
settlement, compromise or consent includes as an

                                       42
<PAGE>

unconditional term thereof the giving by the claimant, petitioner or plaintiff,
as applicable, to such Indemnified Party of a release from all liability with
respect to such Third Party Claim.

     (d)  In the event any of the conditions in Section 6.4(b) above is or
                                                --------------
becomes unsatisfied, however, (i) the Indemnified Party may defend against, and
consent to the entry of any judgment or enter into any settlement with respect
to, the Third Party Claim in any manner it reasonably may deem appropriate (and
the Indemnified Party need not consult with, or obtain any consent from, any
Indemnifying Party in connection therewith), (ii) the Indemnifying Parties will
reimburse the Indemnified Party promptly and periodically for the costs of
defending against the Third Party Claim (including reasonable attorneys' fees
and expenses), and (iii) the Indemnifying Parties will remain responsible for
any Adverse Consequences the Indemnified Party may suffer resulting from,
arising out of, relating to, in the nature of, or caused by the Third Party
Claim to the fullest extent provided in this Article VI.

     8.7  Amendments and Waivers.  No amendment of any provision of this
          ----------------------
Agreement shall be valid unless the same shall be in writing and signed by the
Parties.  No waiver by any Party of any default, misrepresentation, or breach of
warranty or covenant hereunder, whether intentional or not, shall be deemed to
extend to any prior or subsequent default, misrepresentation, or breach of
warranty or covenant hereunder or affect in any way any rights arising by virtue
of any prior or subsequent such occurrence.  No waiver shall be effective
hereunder unless contained in a writing signed by the Party sough to be charged
with such waiver.

     8.8  Severability.  If any provision of this Agreement or any other
          ------------
Transaction Document or the application thereof to any person or circumstance is
held by a court of competent jurisdiction to be invalid, void or unenforceable,
the remaining provisions hereof, or the application of such provision to Persons
or circumstances other than those as to which it has been held invalid, void or
unenforceable, shall remain in full force and effect and shall in no way be
affected, impaired or invalidated thereby, provided, that if any provision

hereof or thereof or the application of any such provisions shall be so held to
be invalid, void or unenforceable by a court of competent jurisdiction, then
such court may substitute therefor a suitable and equitable provision in order
to carry out, so far as may be valid and enforceable, the intent and purpose of
the invalid, void or unenforceable provision and, if such court shall fail or
decline to do so, the Parties shall negotiate in good faith a suitable and
equitable substitute provision. To the extent that any such provision shall be
judicially unenforceable in any one or more states, such provision shall not be
affected with respect to any other state, each provision with respect to each
state being construed as several and independent.

     8.9  Fees and Expenses.  (a)  The Company shall be responsible for the

incurred in connection with any filings to be made with any governmental agency.
The Company also agrees to reimburse the Purchasers for all out-of-pocket
expenses reasonably incurred by the Purchasers in connection with the
Transaction Documents and the transactions contemplated thereby, regardless of
whether or not the transactions are consummated, including, without limitation,
