certificates,   permits,   franchises  and  other  governmental   authorizations
necessary to the ownership of their  respective  properties or to the conduct of

non-compliance  with such laws,  ordinances or governmental rules or regulations
or  failures  to  obtain or  maintain  in effect  such  licenses,  certificates,

     The  Company  and ICON will and will  cause each of their  Subsidiaries  to
maintain, with financially sound and reputable insurers,  insurance with respect
to their  respective  properties  and  businesses  against such  casualties  and
contingencies,  of such  types,  on such  terms and in such  amounts  (including

properly  conducted at all times,  provided  that this Section shall not prevent
the Company,  ICON or any of their Subsidiaries from discontinuing the operation


                                       12
<PAGE>

accordance  with  GAAP  or  IAAP  on the  books  of the  Company,  ICON  or such

aggregate could not reasonably be expected to have a Material Adverse Effect.

           The  Company  and ICON  will at all times  preserve  and keep in full
force and effect its  corporate  existence.  Subject to Section 13.2 the Company

full  force and  effect  the  corporate  existence  of each of its  Subsidiaries
(unless  merged  into the  Company,  ICON or a  Subsidiary)  and all  rights and
franchises  of the  Subsidiaries  unless,  in the  good  faith  judgment  of the
Company,  the  termination  of or failure to preserve and keep in full force and

<PAGE>

           This  Agreement  and  the  Secured  Notes  may be  amended,  and  the
observance  of any term  hereof or of the  Secured  Notes may be waived  (either
retroactively or prospectively), with (and only with) the written consent of the
Company  and the  holders of a majority  in  aggregate  principal  amount of the
Secured  Notes at the time  outstanding  except that (a) no  amendment or waiver
will be  effective as to you unless  consented to by you in writing,  and (b) no
such amendment or waiver may,  without the written consent of the holder of each
Secured  Note at the time  outstanding  affected  thereby,  (i)  subject  to the
provisions  of Section 15 relating to  acceleration  or  rescission,  change the
amount or time of any  prepayment or payment of principal of the Secured  Notes,
(ii) change the  percentage  of the  principal  amount of the Secured  Notes the
holders of which are  required to consent to any such  amendment  or waiver,  or
(iii) amend any of Sections 5, 10, 14(a), 14(b), 15 or 19.

19.2. Solicitation of Holders of Secured Notes.

           The  Company  will  provide  the  Collateral  Agent  with  sufficient

with respect to any proposed  amendment,  waiver or consent in respect of any of
the provisions hereof or of the Secured Notes. The Company will deliver executed
or true and  correct  copies  of each  amendment,  waiver  or  consent  effected

or impair any right consequent thereon. No course of dealing between the Company
and the  holder of any  Secured  Note nor any  delay in  exercising  any  rights
hereunder or under any Secured  Note shall  operate as a waiver of any rights of
any  holder  of such  Note.  As used  herein,  the  term  "this  Agreement"  and

amended or supplemented.

           Any provision of this Agreement  that is prohibited or  unenforceable

of such  prohibition  or  unenforceability  without  invalidating  the remaining
provisions  hereof,  and  any  such  prohibition  or   unenforceability  in  any
jurisdiction  shall (to the full  extent  permitted  by law) not  invalidate  or
render unenforceable such provision in any other jurisdiction.
