MedSurg and Isolyser of their respective  responsibilities under this Agreement,
MedSurg and Isolyser  shall  possess,  use and occupy the premises  described on
Exhibit G hereto (the  "Facilities").  The parties acknowledge that the tenant's
interest  in the MSI Lease  described  on said  Exhibit G has been  assigned  to
Allegiance, but that the tenant's interest in the Curtis Lease described on said
Exhibit G is currently held by MedSurg.  In order to facilitate the  performance

without  regard to  insurance  coverage,  Isolyser  and  MedSurg  shall bear all
reasonable risk of loss of, other than mutually agreed  deductibles any tangible

Assets  remain in the  possession  of Isolyser or MedSurg.  Notwithstanding  the
foregoing,  Allegiance  shall be permitted access to the Facilities at all times
during the term of this Agreement.

10. STANDARD OF CARE.  Isolyser will cause MedSurg to perform the  manufacturing

prudence customarily  exercised by similarly situated persons performing similar
functions,  and  shall  refrain  and  shall  cause  its  employees,  agents  and
representatives  to refrain from engaging in any negligent  acts or omissions in
the  performance  of such services  which result in material  damages.  Isolyser

against any and all claims, damages,  liabilities,  losses, costs,  obligations,
awards, judgments,  fines, penalties, fees, expenses or other charges (including
fees of counsel and other  out-of-pocket  costs) arising from Isolyser=s failure
to perform its obligations under this Section 10.

11. PRODUCT WARRANTIES.  Isolyser warrants that the Products manufactured for or
otherwise  supplied to  Allegiance  under this  Agreement  shall:  (i) have been
manufactured  in  accordance  with  all  applicable  statutes,   ordinances  and
regulations,  including without  limitation,  the U.S. Food, Drug & Cosmetic Act
and the  regulations  promulgated  thereunder  (the  "Act")  including  the Good
Manufacturing  Practice  regulations  which are now in force or are subsequently
adopted   ("Good   Manufacturing   Practices")   by  the  U.S.   Food  and  Drug
Administration  (the "FDA"), the Medical Device Directive  regulations,  and the
Quality System  Regulations  ("QSR") which are now in force or are  subsequently

MedSurg or its  suppliers;  and (v) when  shipped  from the  Facilities,  not be
adulterated or misbranded  within the meaning of any applicable  law,  except to
the  extent  that  any such  adulteration  or  misbranding  is  attributable  to

12.      INSPECTION AND ACCEPTANCE.

          (a)  Isolyser  will  cause  MedSurg  to test and  inspect  each lot of
Product for compliance with the Specifications prior to the release and shipment
thereof to Allegiance or its customer.  Isolyser will cause MedSurg to provide a
certificate  of analysis with each shipment of each lot of Product signed by the
responsible MedSurg quality official.  This certificate of analysis must include
the results (whether numerical or otherwise) for each test performed that verify
that the applicable lot of Product is in compliance with the Specifications,  as
well as a statement that the subject lot was manufactured in compliance with the
requirements enumerated in Section 11 above.

         (b) Allegiance shall  periodically,  in its sole  discretion,  test and
inspect certain lots of Products upon receipt thereof. Upon any such testing and
inspection, Allegiance may reject any lot of Products if it does not comply with
the  Specifications  by giving Isolyser  written notice of such  rejection.  Any
written  notice of  rejection  by  Allegiance  given to  MedSurg  shall  include
identification of the lot number and a description of the Specification failure.

         (c)  Following  receipt of written  notice of rejection of a particular
lot of Product, MedSurg shall, at Allegiance's option, and at MedSurg's expense,
provide  a credit,  refund  or prompt  replacement  of  product  to  Allegiance;
provided,  however  that if MedSurg  does not agree with  Allegiance's  claim of
noncompliance  with the  Specifications,  then the  parties  shall  designate  a
mutually  acceptable  third-party  laboratory  to make a  determination  on such
matter  from a  sample  obtained  from  the lot  shipped  to  Allegiance  or its
customer.  The decision of the  third-party  laboratory  shall be binding on all
parties  hereto  and  all  expenses  related  to  such  third-party   laboratory
investigation  shall be borne by the  party  found to have been  mistaken  as to
compliance or noncompliance of the Product.  Should such third-party  laboratory
confirm  Allegiance's claim,  Isolyser shall at Allegiance's  request,  promptly
provide Allegiance with a credit, refund or prompt replacement of Product.

         (d) Allegiance or its customers  shall return any rejected  products to
MedSurg,  at MedSurg's expense, to an address that Isolyser may designate within
forty-five (45) days of MedSurg receiving written notice of rejection; provided,
however, that if MedSurg does not agree with Allegiance's claim of noncompliance
with  Specifications,  Allegiance  shall not be obligated to return the rejected
Products  to  Isolyser  until  within   forty-five   (45)  days  after  a  final
determination  is made by a  third-party  laboratory  that such  Products do not
comply with  Specifications  as provided in subparagraph (c) above.  Absent such
designation  of  address,   Allegiance   shall  ship  rejected  product  to  the
Facilities.  All reasonable freight, insurance and other costs of such shipment,
along with any risk of loss, shall be borne by Isolyser.


13.      PRODUCT LIABILITY.

         (a)  Indemnification.  Isolyser  shall  indemnify  and hold  Allegiance
harmless against all claims, actions, costs, expenses (including court costs and
legal  fees on a full  indemnity  basis) and other  liabilities  ("Liabilities")
arising  out of or in  connection  with (a) any  product  liability  claim  with
respect to any Product; (b) MedSurg's failure to comply with the Specifications;
(c) any Liabilities  incurred by Allegiance  relating to MedSurg's  manufacture,
storage,  packaging,  handling or shipping of any Product; and (d) any breach of
any  representation,  warranty or covenant  contained in this  Agreement made by
Isolyser or MedSurg to Allegiance.

         (b)  Insurance.  Isolyser  shall  take out and  maintain  comprehensive
general  liability  insurance on an occurrence  form covering each occurrence of
bodily injury and property  damage in an amount  approved by Allegiance  and not
less  than  Three  Million  Dollars  ($3,000,000)  combined  single  limit  with
endorsements  providing  coverage  for: (i) products  and  completed  operations
liability;  (ii) blanket  contractual  liability  (deleting  any  exclusion  for
products and completed  operations  liability);  and (iii)  vendor's  liability.
Isolyser shall cause MedSurg and Allegiance to be named as an additional insured
on such policy.  Upon  execution of this  Agreement,  Isolyser will  immediately
furnish  to  Allegiance  a  certificate  of  insurance  issued  by  the  carrier
evidencing the foregoing endorsements, coverages, limited, and stating that such
insurance  shall not be  cancelable  without  at least  thirty  (30) days  prior
written notice to allegiance.

14.      REGULATORY MATTERS.

         (a) Quality Assurance. Each lot of Product to be supplied to Allegiance
hereunder  shall be  subject  to a quality  assurance  inspection  by MedSurg to

by  MedSurg.  At least  ninety  (90) days  prior to  implementation  of any such
change,  MedSurg  agrees to advise  Allegiance  in writing of such and to obtain
Allegiance's  prior  written  consent  to do  so,  which  consent  shall  not be
unreasonably  withheld.  Upon the  implementation of any change  contemplated by
this Section 14(b),  Allegiance shall make any appropriate  notifications to the
FDA and/or any other applicable regulatory authority or agency and shall provide
copies of such notification to MedSurg as promptly as practicable, provided that
Allegiance may exclude any  information  deemed  confidential  or  competitively
sensitive.

         (c)  Validation.  MedSurg  shall  be  responsible  to  ensure  that all
facilities,  utilities,  equipment and the processes utilized to manufacture the
Products are satisfactorily  validated  according to the FDA guidelines,  to the
extent  applicable,  except to the extent that such  facilities,  equipment  and
processes were not so validated as of the date hereof.






         (d) Batch Records.  Records which include the  information  relating to
the  manufacturing,  packaging  and quality  operations  for each lot of Product
shall be  prepared  by  Isolyser  or  MedSurg  for  each  lot at the  time  such
operations  occur.  Such  records  shall be  prepared  in  accordance  with Good
Manufacturing  Practices and Isolyser's  standard  operating  procedures.  These
documents  for  each  lot  may be  reviewed  during  normal  business  hours  by
Allegiance at Isolyser's  sites of manufacturing of the Products upon Allegiance
giving  seven (7) days  written  notice of its intent to review such  documents.
Allegiance  shall be permitted to review such  documents as soon as  practicable
after giving notice to Isolyser of its intent to do so. MedSurg shall keep batch
records  for each lot of Product  for a period of time  required  by any and all
applicable statutes, ordinances and regulations,  including with limitation, the
Act and the regulations promulgated by the FDA.

         (e)  Regulatory  Visits and  Inspections.  MedSurg shall permit FDA and
other regulatory agents to perform routine inspections of the Facilities and any
other facilities which contain the manufacturing operations for the Products and
shall immediately  notify Allegiance of any such regulatory  inspections and the
results thereof that affect the manufacturing  processes of the Products or that
may impair MedSurg's ability to supply Products to Allegiance. Should any issues
arise in the course of such  inspection,  Isolyser and Allegiance  shall consult
with each other in resolving  such issues.  Upon  reasonable  advance  notice to
MedSurg's plant manager at the applicable facility,  Isolyser shall allow a duly
authorized  representative of Allegiance to enter and inspect such facility from
time to time during  normal  business  hours to monitor  MedSurg's  adherence to
quality assurance and regulatory compliance standards.

         (f) Regulatory Correspondence. Isolyser shall deliver to Allegiance all
copies of correspondence between Isolyser or MedSurg and any regulatory agencies
or authorities  that in any way may impair the ability of Isolyser or MedSurg to
comply with their obligations under this Agreement.  Isolyser shall deliver such
correspondence  to Allegiance  within five (5) business days of  distributing or
receiving such correspondence, as the case may be.

         (g) No Debarred Service Providers.  To their knowledge after reasonable
inquiry,  Isolyser  and  MedSurg  have  not and  will  not use the  services  of
employees or  subcontractors  who have been  debarred by the FDA, in  connection
with complying with its obligations under this Agreement.






         (h) Product Complaints.  In the event that Isolyser or MedSurg receives
any complaints  regarding the Products,  it shall promptly notify  Allegiance of
such.  Isolyser shall be responsible  for  evaluating  and  investigating  these
complaints and communicating the results thereto to Allegiance in writing within
ten (10) business days of notification; provided that, if any such investigation
requires more than ten (10) business days to complete,  Isolyser shall so notify
Allegiance  of such in writing  within the  aforesaid  ten (10)  business  days.
Isolyser will make a preliminary  evaluation of each complaint received and will
conduct all follow-up, communications and maintenance of records with respect to
such complaints as required by applicable law and will cooperate with Allegiance
in the resolution of such product  complaints.  Allegiance  shall be responsible
for  making  all  necessary  reports  to the FDA  and/or  any  other  applicable
regulatory  agency or  authority  and shall  provide  copies of such  reports to
Isolyser as promptly as  practicable,  provided that  Allegiance may exclude any
information deemed confidential or competitively sensitive.

         (i)      Recall Action.

                  (i) In the  event  Allegiance  should  be  required  or should
voluntarily decide to initiate a recall, Product withdrawal, or field correction

its recall letter.  In conjunction with such recall,  Isolyser and MedSurg shall
assist in the investigation to determine the cause and extent of the problem and
the parties shall fully  cooperate with each other  concerning the necessity and
nature of such action.

                  (ii) In the event that Isolyser  independently believes that a
recall, Product withdrawal or field of correction for any of the Products may be
necessary or appropriate, Isolyser shall notify Allegiance of Isolyser's belief,
and the parties shall fully  cooperate with each other  concerning the necessity
and nature of such action.

                  (iii)  All  coordination  of any  recall  or field  correction
activities  involving any of the Products shall be handled by Allegiance whether
