promises, variances, judgments, extents, executions, claims, and demands, of any
type whatsoever,  including any claim for indemnity or for contribution, in law,
admiralty, or equity, that any of Jean-Francois Rossignol,  Romark Laboratories,
L.C. and/or Marc S. Ayers now has, ever had, or that may hereafter have, whether
known or unknown,  suspected or unsuspected,  potential or actual,  asserted, or
warranted,  from  the  beginning  of the  world  up to the  date of this  letter
agreement.  This release shall not  constitute a release of any  obligations  or
duties  expressly  and  specifically  imposed  upon  any  Party  by this  letter
agreement,  nor shall it  constitute a release of any claims made in the pending
court case,  Ayers v.  Belmac,  Case No.  93-4515,  in the  Thirteenth  Judicial
Circuit of Florida. This release shall become effective immediately upon payment
of the final $100,000  installment  due on or before March 3, 1996, as set forth
above.

As consideration  for the payments made pursuant to this letter  agreement,  the
settlement of the pending court case and the pending arbitration and the release
provided  herein,  Belmac  Corporation  hereby  releases and forever  discharges
Jean-Francois Rossignol,  Romark Laboratories,  L.C. and Marc S. Ayers and their
employees, agents, partners, attorneys,  affiliates,  representatives,  privies,
successors,  assigns,  shareholders,  directors, officers, and subsidiaries from
any and all actions, causes of action, lawsuits, arbitrations, injuries, losses,
payments,  attorneys' fees, benefits,  rights,  damages, costs, loss of service,
loss of opportunities,  loss of profits, liens, expenses,  compensation,  suits,
debts, dues, sums of money,  accounts,  reckonings,  bonds, stock claims, bills,
securities,  specialities,  covenants,  contracts,  controversies,   agreements,
promises, variances, judgments, extents, executions, claims, and demands, of any
type whatsoever,  including any claim for indemnity or for contribution, in law,
admiralty,  or equity,  that Belmac  Corporation  now has, ever had, or that may
hereafter have, whether known or unknown, suspected or unsuspected, potential or
actual,  asserted, or warranted,  from the beginning of the world up to the date
of this letter  agreement.  This release  shall not  constitute a release of any
obligations or duties expressly and specifically  imposed upon any Party by this
letter  agreement,  nor shall it  constitute a release of any claims made in the
pending  court  case,  Ayers v.  Belmac,  Case No.  93-4515,  in the  Thirteenth
Judicial  Circuit of Florida.  This release shall become  effective  immediately
upon payment of the final $100,000  installment due on or before March 31, 1996,

The Parties  agree to file,  on or before  December 8, 1995, a  stipulation  for
voluntary  dismissal with regard to the pending court case (Belmac v. Rossignol,

Jean-Francois  Rossignol  agrees,  on or before December 8, 1995, to dismiss the
pending arbitration (American Arbitration Association Case No. 33-133-00050-95).
Each of the Parties will bear their own attorneys' fees and costs.

Finally,  the Parties agree that they have not relied upon any  representations,
statements,  inducements,  acts or omissions of any other Party in entering into
this letter agreement. Because




                                                                                






of the history and nature of the litigation and the relationship of the Parties,
it would be unreasonable for the Parties to rely upon any such  representations,
statements,  inducements,  acts or omissions of any other party. Therefore,  the
Parties hereby expressly and specifically  waive any and all claims for fraud in
the inducement,  recision, and any other claims relating to the validity of this
letter agreement.
