provisions  of this  Section,  IBC or  Empyrean  shall be entitled to enjoin the
other party from use and  dissemination  of any and all the respective  parties'
confidential information.

     4. PROTECTION OF THE FORMULATION

     (a)  Empyrean   acknowledges  that  the  Formulation  is  confidential  and
proprietary  information  owned by IBC and that it does not have any right in or
to the  Formulation  except as provided in Section 5. Empyrean agrees to protect

                                        5

the  confidentiality  of the  Formulation in accordance with Section 3 above and
further  agrees to make no  disclosure  of the  Formulation  to any third  party
should Empyrean know or come to know the Formulation.

     5. EXCLUSIVE LICENSE FROM IBC TO EMPYREAN

     (a) IBC grants to Empyrean an exclusive right and license in the Territory:

          (i) to purchase from an Approved Manufacturer Licensed Products and/or
products  containing the Formulation for packaging into a Licensed Product by an
Approved Packager; and

          (ii) to use, have used, sell and have sold the Licensed Products.

     (b) Empyrean  agrees to use reasonable  commercial  efforts,  and to expend
within five (5) years of  executing  this  Agreement,  if  necessary,  up to ten
million United States dollars (US$10,000,000) to market the Licensed Products in
the Territory during the term of this Agreement.

     6. EXCLUSIVE LICENSE

         (a) The License  from IBC to  Empyrean,  as defined in Section 5 above,
shall be exclusive  during the term of this Agreement.  IBC covenants and agrees
not  to  sell  the  Formulation  or  Licensed  Products  to  any  person,  firm,
partnership,  corporation  or other entity other than Empyrean in the Territory,
and agrees not to sell the Formulation or Licensed Products to any person, firm,
partnership,  corporation or other entity that sells Licensed  Products into the
Territory,  and shall not grant any right or appoint any distributor or licensor
other than Empyrean to purchase,  sell, use, market, offer to sell or distribute
the  Formulation  or the Licensed  Products in the  Territory.  In the event IBC
breaches the provisions of this Section,  Empyrean may, in addition to its other

                                        6

rights,  including damages, enjoin any such breach upon thirty (30) days written
notice specifying the nature of such breach,  unless,  within such 30-day period
IBC  discontinues  such breach and provides a written notice to Empyrean of such
discontinuance  together  with the  identification  of the steps taken by IBC to
discontinue such breach.

     7. ROYALTIES

     (a) For the Term of this  Agreement,  Empyrean  shall  pay to IBC a Royalty
which shall be computed as five percent (5%) of Empyrean's Net Sales of Licensed
Products to any third party.

     (b) Empyrean  shall pay all Royalties to IBC quarterly,  within  forty-five
(45) days after the end of each calendar quarter.

     (c) IBC acknowledges that Empyrean's  obligation to pay royalties to IBC is
based upon Empyrean's  exclusive  right to sell,  offer for sale, and distribute
Licensed  Products in the Territory.  If, during the Term of this  Agreement,  a
third party not a sublicensee,  distributor or joint venturer of Empyrean sells,
offers  for sale,  or  distributes  Licensed  Products  in the  Territory  which
products originate in whole or in part from IBC ("Third Party Sales"),  Empyrean
shall  promptly  notify IBC in writing of such Third Party Sales,  including the
name of such Third Party and the type of Licensed  Product  being sold,  offered
for sale or  distributed  in  accordance  with the terms set forth in Section 19
below.  After formal notice of Third Party Sales from Empyrean to IBC,  Empyrean
shall also have the right seek a preliminary injunction against IBC or any third
party to enjoin any such Third Party Sales upon thirty (30) days written  notice
specifying  the nature of such Third  Party  Sales,  unless,  within such 30-day
period  such  Third  Party  Sales  discontinue.  If  it is  established  through
arbitration  that such Third Party Sales are the fault,  in whole or in part, of
IBC then  Empyrean  shall have the right to cease  paying  Royalties  thereafter
incurred by Empyrean until such Third Party Sales cease.

                                        7

     (d) If, during the Term of this Agreement,  Empyrean is forced or otherwise
obligated  to pay a royalty  to a third  party for sale or  distribution  of the
Licensed  Products in the  Territory  by reason of such third  party's  claim of
patent or trade secret rights in or to the Formulation or the Licensed Products,
any and all Royalties thereafter incurred by Empyrean under this Agreement shall
be reduced by an amount equal to such royalties paid to such third party.

     8. REPORTING AND RECORD KEEPING

     (a) Within  forty-five  (45) days after the end of each  calendar  quarter,
irrespective  of whether any Net Sales have been made or whether any sum is then
due to IBC,  Empyrean  shall  deliver to IBC via  regular  mail a  complete  and
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
herein to compute Net Sales in specific  detail,  so as to  reasonably  allow an
audit of underlying  documents,  together  with  Empyrean's  calculation  of the
amount of royalties then due IBC for the period covered by such report.

     (b)  Empyrean  shall  keep or  cause  to be  kept  accurate,  complete  and
up-to-date  books of accounts  separately  stating by clear means records of all
sales of the Licensed Products  including records pertaining to invoiced amounts
by  customer  and  records   pertaining  to  all  freight  charges,   discounts,
allowances,  and returns allowed by Empyrean. Such books and records of accounts
shall  reflect  that a sale of the  Licensed  Products  shall be  deemed to have
occurred as of the date such  Licensed  Products  were  invoiced  to  Empyrean's
customers.

                                        8

     (c) IBC or its authorized  representatives  shall have the right, once each
calendar  year,  to inspect all records of Empyrean with respect to the Licensed
Products  and to make  copies of said  record  utilizing  Empyrean's  facilities
without charge and shall have free and full access thereto on reasonable  notice
during the normal business hours of Empyrean.  In the event that such inspection
or audit reveals an  underpayment  by Empyrean  under this  Agreement,  Empyrean
shall  immediately  pay to IBC 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 IBC until all such amounts
have been paid in full. Further, if such inspection or audit discloses that, for
the annual period reviewed or audited, Empyrean has underpaid or understated its
obligation  under this Agreement by twenty percent (20%) or more,  then Empyrean
shall also pay three times the reasonable  professional  fees of the independent
representatives  (such as auditor  and  attorneys'  fees)  engaged to conduct or
review such inspection or audit.

     9. MODIFICATION OF THE FORMULATION

     (a) Neither IBC nor Empyrean shall alter,  modify or change the Formulation
for use in the Licensed  Products in the Territory  without first  obtaining the
written approval of IBC-Empyrean LLC.

     10. THE GEL PRODUCT

     (a) IBC  covenants  and agrees to use its best  efforts to take any and all
required  action to seek and secure the  approval of the United  States Food and
Drug  Administration  (the "USFDA") to manufacture,  distribute and sell the Gel
Product,  provided,  however,  that Phase III data shows statistics that clearly
demonstrate the efficacy of the Gel Product.

                                        9

     (b) IBC further  covenants and agrees to expend,  if  necessary,  up to ten
million  United States  dollars  (US$10,000,000)  in  connection  with the USFDA
approval.  For the  avoidance  of doubt,  IBC shall not be required to spend ten
million United States dollars  (US$10,000,000)  for such clinical  trials if the
clinical trials can be successfully conducted for a lesser amount. IBC agrees to
prepare and  conduct  all such  clinical  trials,  and to prepare all  necessary
materials  required in order to achieve approval from the applicable  regulatory
bodies  for the Gel  Product,  in such a way as to  ensure  that  such  clinical
trials,  the results of such clinical trials and/or all materials  produced as a
result of or in connection with achieving  regulatory  approval shall be in such
condition  so as to be  admissible  and  acceptable  to the  USFDA and any other
regulatory  agencies in the United States  required to permit the Gel Product to
be sold in the United States.

     (c) IBC agrees to use its best  efforts to  commence  the  appropriate  and
necessary  governmental  regulatory  approvals  to market the Gel Product in the
United States as preventing the transmission of chlamydia,  gonorrhea, syphilis,
Trichomonas,  herpes I and II  within  twelve  (12)  months  of the date of this
Agreement,  provided, however, that Phase III data shows statistics that clearly
demonstrate the efficacy of the Gel Product.

     (d) IBC agrees to use its best  efforts to  commence  the  appropriate  and
necessary  governmental  regulatory  approvals  to market the Gel Product in the
United  States as  preventing  the  transmission  of HIV within twenty four (24)
months of the date of this  Agreement,  provided,  however,  that Phase III data
shows statistics that clearly demonstrate the efficacy of the Gel Product.

                                       10

     11. TERM

     (a) The term of this Agreement  shall begin on the Effective Date and shall
continue for a period of ten (10) years (the "Initial Term").

     (b) This Agreement shall be automatically  renewed at the conclusion of the
Initial Term, and each subsequent Additional Term, if applicable, for Additional
Terms of ten (10) years, unless terminated in accordance with Section 12 below.

     12. TERMINATION

     (a) IBC shall  have the right to  terminate  this  Agreement  upon  written
notice to  Empyrean  at least  sixty (60) days prior to the end of any  calendar
year, in the event that Empyrean,  its affiliates and/or  distributors,  sell no
Licensed Products in the Territory for a period of two (2) years.

     (b)  In  the  event  that  Empyrean  otherwise   materially  breaches  this
Agreement,  IBC's sole remedy shall be to seek specific performance by filing an
appropriate  action in  arbitration,  in the event  Empyrean  fails to cure such
breach within sixty (60) days after  receipt of written  notice of such material
breach.

     (c) If, within the first two years of this Agreement, Empyrean fails to pay
any Royalties  with respect to a calendar  quarter for which  Royalties are due,
IBC's  sole  remedy  shall be the right to bring an action  in  arbitration  for
payment of such  Royalties,  plus  interest at the prime  interest rate plus 6%,
plus  attorneys  fees,  in the event  Empyrean  fails to cure such breach within
sixty (60) days after receipt of written notice of such breach.

     (d) If, within the third, fourth and fifth year of this Agreement, Empyrean
fails  to pay any  Royalties  with  respect  to a  calendar  quarter  for  which
Royalties  are due, IBC shall,  in addition to the remedies set forth in Section

                                       11

12 (c)  above,  have the right to  convert  Empyrean's  exclusive  license  to a
non-exclusive  license,  in the event  Empyrean fails to cure such breach within
sixty (60) days after receipt of written notice of such breach.

     (e) If, after the fifth year of this  Agreement,  Empyrean fails to pay any
Royalties  with respect to a calendar  quarter for which  Royalties are due, IBC
shall,  in addition to the  remedies set forth in Sections 12 (c) and (d) above,
have the right to terminate this Agreement,  in the event Empyrean fails to cure
such  breach  within  thirty (30) days after  receipt of written  notice of such
breach.  IBC shall not be obligated  to arbitrate  its right to any remedy under
this subsection 12(e).

     13. PRESS RELEASES

     (a) IBC and Empyrean  each agree that, in the event either party desires to
issue a press release that refers to the other party by name,  the party issuing
the press release shall, in advance,  submit a copy of such press release to the
other  party  for the  other  party's  approval,  which  approval  shall  not be
unreasonably   withheld;   provided,   however,   that  the  foregoing  approval
requirement  shall not apply in such  circumstances  where a party shall, on the
advice  of  counsel,  issue a press  release  in order to  comply  with any then
applicable  Federal or state  securities law disclosure  requirement.  The other
party  shall have two (2)  business  days to object to such press  release.  The
failure of the other party to object,  or approve,  within two (2) business days
will be deemed by the issuing party as an approval of the press release.

     14. NO PARTNERSHIP or JOINT VENTURE

     (a) Nothing  herein  contained  shall be construed so as to constitute  the
parties  hereto as  partners  or as joint  venturers,  or either as agent of the
other, and neither IBC nor Empyrean shall have the power to obligate or bind the
other in any manner whatsoever.
