     4. ROYALTIES

     (a) For the Term of this  Agreement,  IBC shall pay to  Empyrean  a Royalty
which  shall be  computed  as five  percent  (5%) of IBC's Net Sales of Licensed
Products  in the  Territory  to any  third  party.  Royalties  shall be  payable
regardless  of whether the Licensed  Product  contains  Empyrean  Trade Dress or
Trademark.

(45) days after the end of each calendar quarter.

accurate written  statement  setting forth the amount of Licensed Products sold,
the gross price at which such  Licensed  Products  were sold,  the amount of any
discount or allowances  given  consistent with the terms of this Agreement,  the
credit for Licensed Products allowed to be returned and other deductions allowed

     5. REPORTING AND RECORD KEEPING

     (a) IBC shall keep or cause to be kept  accurate,  complete and  up-to-date

and  records  pertaining  to all freight  charges,  discounts,  allowances,  and

sale of the Licensed  Products  shall be deemed to have  occurred as of the date
such Licensed Products were invoiced to IBC's customers.

                                        5

     (b) Empyrean or its authorized  representatives  shall have the right, once
each  calendar  year,  to inspect  all such  records of IBC with  respect to the
Licensed  Products and to make copies of said record  utilizing IBC's facilities
without charge and shall have free and full access thereto on reasonable  notice
during the normal  business  hours of IBC. In the event that such  inspection or
audit reveals an underpayment by IBC under this Agreement, IBC shall immediately
pay to Empyrean the balance of all such amounts found to be due pursuant to such
audit or  inspection  together  with  interest  thereon at the "best  commercial
customer" rate at the Bank of America,  plus six percent (6%) per annum from the
date such amounts first became due to Empyrean  until all such amounts have been
paid in full.  Further,  if such  inspection or audit  discloses  that,  for the
annual  period  reviewed  or  audited,  IBC has  underpaid  or  understated  its
obligation  under this Agreement by twenty percent (20%) or more, then IBC shall
also  pay  three  times  the  reasonable  professional  fees of the  independent
representatives engaged to conduct or review such inspection or audit.

     6. TRADEMARK

     (a) IBC  recognizes  that  Empyrean  is the owner of all  right,  title and
interest in and to the Trademark in any form or  embodiment  thereof and is also
the  owner of the  goodwill  attached  or which  shall  become  attached  to the
Trademark  in  connection  with the  business and goods in relation to which the
same has been,  is, or shall be used.  Sales by IBC shall be deemed to have been
made by Empyrean for the  purposes of goodwill and all uses of the  Trademark by
IBC shall inure to the benefit of Empyrean and any rights of Empyrean. IBC shall
not at any time  intentionally  or  recklessly do or suffer to be done by anyone
acting on its behalf or in  connection  with IBC any act or thing  which will in
any way impair the rights of Empyrean in or to the Trademark or any  application
or registration  thereof or which  depreciates the value of the Trademark or its
reputation.

                                        6

     (b) IBC shall, at the request of Empyrean, fully cooperate with Empyrean in
preparing,  executing  and  causing  to be  recorded  or filed  such  agreements
(including registered user agreements and other documents reasonably required by
Empyrean)  to  confirm  the  ownership  by  Empyrean  of the  Trademark,  and to
evidence,  protect and implement its rights to the Trademark  within and outside
the  Territory  and the  respective  rights of Empyrean and IBC pursuant to this
Agreement.  Empyrean  and IBC  acknowledge  that  only  Empyrean  may  file  and
prosecute  trademark  applications  regarding  the Trademark or IBC's use of the
Trademark anywhere.  IBC will cooperate with Empyrean, at Empyrean's request, in
connection  with  the   preparation,   execution,   filing  and  prosecution  of
applications to register the Trademark both inside and outside the Territory and
the  maintenance  of  such  registrations  as  may  issue.  Upon  expiration  or
termination  of this Agreement for any reason  whatsoever,  IBC will execute and
file  such  documents  as shall  be  required  by  Empyrean,  including  without
limitation, termination of any agreements and assignments of rights.

     (c) IBC shall cause to appear on all Licensed Products and on all materials
on or in connection  with which the Trademark is used such legend,  markings and
notice of any  trademark,  trade  name or other  rights  therein  or  pertaining
thereto as Empyrean  shall  reasonably  require and shall comply with all notice
and marking requirements of any law applicable or necessary to the protection of
the Trademark.

     (d) IBC  shall  never (i)  challenge  Empyrean's  ownership  of or right to
license,  or the validity of, the Trademark,  any application  for  registration
thereof or any  trademark  registration  thereof nor (ii)  contest the fact that
IBC's rights under this Agreement are solely those of a Licensee.

     (e) At the expiration or termination of this Agreement, except as expressly
provided  herein,  all rights of IBC with respect to use of the Trademark  shall
thereupon cease and terminate for all purposes whatsoever.

the Trademark and Trade Dress requires Empyrean to reasonably  control the type,
image and  quality of products  manufactured  and sold using the  Trademark  and
Trade Dress and the use of the Trademark and Trade Dress in connection  with the
manufacture and sale of Licensed Products.

     (b)  IBC  shall  only  use  the  Trademark  on  the  Licensed  Products  in

Empyrean, or as Empyrean may direct, for Empyrean approval,  free of charge, one
(1)  pre-production  sample and six (6) production  samples  related to same, of

understanding of the parties that IBC may use the same solely in connection with
Licensed Products.

     (g) IBC will use and  display  the  Trademark  and Trade Dress only in such
forms and manners as are approved by Empyrean, specifically, as displayed in the

be required,  such approval,  consent or permission,  shall not be  unreasonably
withheld or delayed. If Empyrean shall deny approval,  it shall state in writing
the reasons  therefor.  After any sample,  copy or art work has been approved by
Empyrean, IBC shall not vary or depart therefrom in any material respect without
the further approval of Empyrean.

the  parties  agree that  co-branding  the  Trademark  and Trade  Dress with the
