sale of  certain  products  which it sells  under  the  OREX(R)  trademark  (the
"OREX(R)  Products") all of which are manufactured  from Isolyser's  proprietary
degradable  polyvinyl  alcohol  ("PVA")  or  novel  dispersal  polymers  ("NDP")
material  which can be dissolved  and then  disposed via normal  sanitary  sewer
systems ("Material"); and

     WHEREAS, Isolyser is also the owner of the trademarks ENVIROGUARD and OREX,
for water soluble fabrics and products made therefrom ("Trademarks"),  for which
registrations  or applications  for  registrations  of said Trademarks have been
filed in various jurisdictions; and

defined); and

     WHEREAS, Isolyser wishes to expand its commercial opportunities through the
manufacture  and  sale  of  the  Material  to  Allegiance  and by  licensing  to
Allegiance  the  Patents  and  Trademarks  relating  to the right to make,  use,
distribute,  sell  and  dispose  healthcare  products  made  from  the  Material
("Products"); and

     WHEREAS,  Allegiance  desires to distribute and sell the Products under the
Trademarks  and Patents and to practice  the methods of disposal as described in
the Patents on the Products as Allegiance may deem appropriate; and

     NOW,  THEREFORE,  in  consideration  of the  premises  and  of  the  mutual
agreements   and   covenants   hereinafter   set  forth,   and  other   valuable
consideration,  the receipt  and  sufficiency  of which is hereby  acknowledged,

                               2.PATENT PROVISIONS

     2.1. PATENT

          2.1.1. PATENT LICENSE FOR PRODUCTS.

               Isolyser  grants to Allegiance a worldwide  exclusive  license to
          make, use and sell Products  embodying or made in accordance  with the
          inventions   claimed  in  the  Patents   within  and  for   healthcare
          applications. "Products" shall include any healthcare device made from
          the Material or an  improvement  of the  Material,  including  but not
          limited to blow molded, injection molded and case extrusion substances
          that are dissolvable  and are made using PVA or NDP  ("Improvements").
          "Patents"  shall  include all patents  owned or controlled by Isolyser
          relating to the Material and shall include, but not be limited to, the
          patents  listed in Exhibit 1 together with any patents which may issue
          upon any pending applications,  continuations,  continuations-in-part,
          divisions, reissues,  reexaminations, or renewals of any such patents,
          as well as any  patents  which  may issue on  Improvements.  The price
          terms of  Improvements  under the Agreement shall be negotiated by the
          parties.




          2.1.2. PATENT LICENSE FOR MATERIALS

               Isolyser grants to Allegiance a worldwide  exclusive royalty free
          license for the Term, and any extension thereof, to use the Patents to
          make  Material  or have  Material  made if  Isolyser is unable to meet
          Allegiance's  requirements.  Allegiance  shall  exercise the foregoing
          license only if during any calendar month Isolyser is unable to supply
          Material  in an amount at least  equal to the amount  supplied  in the
          preceding  calendar month and Isolyser is unable to supply Material in
          such  amount  during  each  of  the  two  following  calendar  months.
          Notwithstanding the foregoing, in the event that Isolyser is unable to
          meet  Allegiance's  requirements  because of the failure of Isolyser's
          suppliers  to supply  Material  to  Isolyser  or  because of demand by
          Allegiance in excess of  Isolyser's  productive  capacity,  Allegiance
          shall not be  entitled  to  exercise  its rights  under the  foregoing
          license  until six months  after  written  notice from  Allegiance  to
          Isolyser  of  Isolyser's   failure  to  satisfy  the  requirements  of
          Allegiance.  If  Isolyser  has  identified  an  alternative  source of
          Materials  and is  satisfying  Allegiance's  requirements  as provided
          above within such six month period,  Allegiance shall not be permitted
          to exercise its rights under the foregoing license.

          2.1.3. RIGHT OF FIRST REFUSAL

               Isolyser  shall submit to Allegiance  specifications  and,  where
          possible,  samples of any and all  Improvements  to the Products which
          Isolyser  may  conceive or reduce to practice  during the term of this
          Agreement.  Within ninety (90) days after such submission,  Allegiance
          may  acquire  rights to such  Improvements  by  advising  Isolyser  in
          writing that Allegiance is electing to have such Improvements included
          within the  definition  of Products and by entering  into an agreement
          with  Isolyser  negotiated  at the time which is determined to benefit
          both parties and maintains a mutually profitable relationship.  In the
          event  Allegiance  does not  elect to  distribute  such new  Products,
          Isolyser  shall have the right to sell those  Products as it deems fit
          in its sole  discretion on terms and conditions no more favorable than
          those offered to Allegiance  under this section.  It being  understood
          that  no  up-front  license  fee  shall  be  required  to be  paid  by
          Allegiance.

     2.2. TRADEMARK LICENSE

          2.2.1. LICENSE GRANT

               Isolyser  grants to Allegiance a worldwide  exclusive  license to
          the  Trademarks   for  use  in  conjunction   with  the  Products  and
          Improvements for healthcare applications, subject to the provisions of
          this Agreement.

          2.2.2. RESERVATION OF RIGHTS IN TRADEMARKS

               The Trademarks are acknowledged by Allegiance to be the exclusive
          property of Isolyser.  Allegiance agrees that the use of any Trademark
          by  Allegiance  anywhere  in the world  shall  inure to the benefit of
          Isolyser.  If Allegiance  determines that a trademark  registration is
          desirable in any country,  it will so advise  Isolyser who may proceed
          to seek the appropriate  trademark  protection in such country, in its
          sole discretion.



                                         [***]- CONFIDENTIAL TREATMENT REQUESTED
     2.3. NO REPRESENTATIONS

     The Patent and Trademark  licenses shall be effective  worldwide.  However,
Isolyser  does not  represent  that it has  patent  or  trademark  rights in any
particular  country and Isolyser is not  obligating  itself by this Agreement to
seek such rights in any country.

     2.4. NON-TRANSFERABLE

     These  licenses  shall be  non-transferable  by Allegiance and shall not be
subject to  sublicenses,  without the express  written  permission  of Isolyser,
except that there shall be an implied  sub-license  to any purchaser of Products
to use such  products  for  their  intended  purpose  and  except  as part of an
assignment not prohibited by Section 5.3.

     2.5. ROYALTIES

          2.5.1. DISSOLUTION ROYALTY

               Allegiance  shall pay  Isolyser  or its  designee  a  dissolution
          royalty  of  [***] of the Net  Sales  Price  of the  Products  for all
          Products which are dissolved by or on behalf of Allegiance's customers
          ("Royalty"),  provided that Isolyser  shall provide  documentation  to
          Allegiance  regarding  the  dissolution  of  such  Products  in a form
          acceptable to  Allegiance.  The term "Net Sales Price" means the total
          receipts  by  Allegiance  from  the  sale of the  Product(s)  less all
          freight,  sales or use taxes, trade discounts,  returns and allowances
          granted  in lieu of  returns.  In the event the  Product  is sold as a
          component of a kit or other  assembly of product,  the Net Sales Price
          for such Products shall be the average Net Sales Price during the same
          calendar  quarter for the Product  when sold alone or as not part of a
          kit.

          2.5.2. REPORTS AND RECORDS

               Allegiance  shall provide  Isolyser with tracing reports of sales
          of Products by Allegiance.  Allegiance  shall keep records showing the
          sales or other  disposition of Products under licenses  granted herein
          in  sufficient  detail to enable the  Royalties  payable  hereunder by
          Allegiance to be determined, and further agrees to permit such records
          to be  examined  by  Isolyser  to the extent  necessary  to verify the
          accuracy  of the  calculation  of the  Royalty  payments  above,  such
          examination  to be made at the expense of  Isolyser  by any  certified
          public  accountant  appointed  by  Isolyser  who  shall be  reasonably
          acceptable to Allegiance,  provided such certified  public  accountant
          executes a confidentiality  agreement covering such books and records.
          Such  examination  shall occur not more than once in any twelve  month
          period during normal business hours.

     2.6. USE OF TRADEMARKS

          2.6.1. CONFUSINGLY SIMILAR MARKS

               Allegiance  shall not use any trademark,  mark, name or symbol in
          conjunction with the Products which may be confusingly  similar to the
          Trademarks  and shall not use the Trademarks in any manner which could
          affect the  validity of their  registration  or  Isolyser's  exclusive
          ownership thereof.  Allegiance shall not make or permit any removal or
          modification  of any  Trademarks  placed by  Isolyser  on  Products or
          associated literature, media, drawings and manuals.



          2.6.2. TRADEMARK INFRINGEMENT

               If, as a result of the use of the Trademarks,  Allegiance, or any
          of   Allegiance's   customers   should  be  charged   with   trademark
          infringement,  Allegiance  shall  immediately  notify  Isolyser  after
          Allegiance receives notice of such charge and Isolyser will assume the
          defense and  expense of any  proceedings  instituted  pursuant to such
          charge. Allegiance shall not institute proceedings for infringement of
          the Trademarks in its own name.  Allegiance  agrees to assist Isolyser
          when  requested  in such  defense  or  protection  of the  Trademarks.
          Isolyser will reimburse Allegiance for out-of-pocket  expenses. If any
          misuse of the Trademarks comes to the Allegiance's attention, it shall
          promptly  notify  Isolyser and  cooperate  with  Isolyser in trying to
          correct such misuse.

          2.6.3. MISLEADING CLAIMS

               Allegiance shall not make any false,  exaggerated,  or misleading
          claim or statement  relating to the Products or the performance of the
          Materials.  If such  claims  or  statements  are  made by  Allegiance,
          Allegiance,   upon  the  request  of   Isolyser,   shall   discontinue
          immediately  any  use,  display,   advertising  or  promotion  of  the
          Trademark  for  the  Products  in  conjunction   with  such  false  or
          misleading claims.

          2.6.4. QUALITY ASSURANCE

               Allegiance shall permit a designated  representative  of Isolyser
          to periodically visit the manufacturing and warehousing  facilities of
          Allegiance  which  manufacture  or store  the  Products,  or any other
          entity  to  whom  Allegiance  has  contracted  all  or a  part  of the
          manufacture of the Products  hereunder,  for the sole purpose to allow
          Isolyser  to  inspect  the  quality of the  Products  in the course of
          manufacture  or in storage;  provided such  representative  executes a
          confidentiality  agreement  and visits during  normal  business  hours
          after reasonable notice.

     2.7. INTELLECTUAL PROPERTY RIGHTS AND OBLIGATIONS

          2.7.1. ISOLYSER RIGHTS

               Nothing in this Agreement shall be construed as:

               (a)  a warranty or  representation by Isolyser as to the validity
                    of any Patent;

               (b)  a warranty or representation that any Product made, used, or
                    sold under any license  granted in this Agreement is or will
                    be free from infringement of the patents of third parties;

               (c)  A   requirement   that   Isolyser   shall  file  any  patent
                    application,  secure  any patent or  maintain  any patent in
                    force; or

               (d)  An obligation to bring or prosecute actions or suits against
                    third parties for infringement.

          2.7.2. WARRANTY

               Notwithstanding   the  foregoing,   Isolyser  warrants  that  the
          Material as manufactured by Isolyser or its disposal by dissolution in
          accordance  with written  guidelines set forth by Isolyser does not to
          Isolyser's knowledge infringe the intellectual  property rights of any
          third party.




          2.7.3. PATENT MARKING

               Allegiance agrees to observe the reasonable written  requirements
          of Isolyser  with  respect to the  marking of  Products  with the word

          Patents  indicated  by  Isolyser  in writing to be  applicable  to the
          Products or its disposal.

     2.8. INFRINGEMENT

          2.8.1. INFRINGEMENT BY ALLEGIANCE

               Allegiance  shall give  Isolyser  prompt  notice of each claim or
          allegation  that  the  manufacture,  use,  or sale  of the  Product(s)
          constitutes  an  infringement  of a patent or patents owned by others.
          Isolyser  shall defend such claims and  allegations at its expense and
          shall indemnify  Allegiance against any and all liabilities,  costs or
          expenses  arising  in  connection  therewith.  If  Isolyser  does  not
          undertake  within thirty (30) days of such notice to defend such claim
          or  allegation,  Allegiance  shall have the right to retain all of the
          Royalties otherwise payable to Isolyser, provided Allegiance uses such
          Royalties  to pay for or defray the costs of  defending  each claim or
          allegation, including the costs of settling or satisfying the claim or
          allegation.   During  the  defense  of  such  claims  or  allegations,
          Allegiance shall submit written reports to Isolyser,  showing payments
          accruing to Isolyser and the expenses of defending  against the claims
          or allegations of  infringement.  Upon  termination of all proceedings
          involving  such  claims or  allegations,  Allegiance  shall  remit the
          balance, if any, of the Royalties accrued but not yet paid to Isolyser
          and not spent by Allegiance under the terms of this provision.  In the
          event of any infringement  claim or allegation as provided above, upon
          the request of Isolyser, Allegiance will cooperate with the defense of
          such claim or allegation.

          2.8.2. SETTLEMENT OF CLAIM OF INFRINGEMENT

               If the  settling  or  satisfying  of any claim or  allegation  of
          patent  infringement  requires  the payment by  Allegiance  to a third
          party of any amounts,  including  royalties for  manufacture,  use, or
          sale of the  Product(s),  Allegiance  shall be  entitled to deduct the
          amounts so paid to a third party from the Royalties due Isolyser under
          this Agreement.




          2.8.3. INFRINGEMENT BY THIRD PARTY

               Upon learning of the  infringement  of a Patent by third parties,
          Allegiance  shall  inform  Isolyser  in writing of that fact and shall
          supply  Isolyser  with  any  evidence  available   pertaining  to  the
          infringement.  Isolyser may at its own expense take whatever steps are
          necessary to stop the infringement and recover damages therefore,  and
          shall be entitled to retain all damages so recovered. If Isolyser does
          not  undertake  within  thirty (30) days of such notice to enforce the
          Patent against the  infringement,  Allegiance  shall have the right to
          take whatever action it deems appropriate in Isolyser=s name or in its
          own  name to  enforce  the  Patent,  to  retain  all of the  Royalties
          otherwise payable to Isolyser, and to use such Royalties to pay for or
          defray the costs of enforcing the Patent against the  infringement  by
          third parties.  During proceedings  relating to the enforcement of the
          Patent,  Allegiance  shall submit written  reports,  showing  payments
          accruing to Isolyser and the expenses of enforcing the Licensed Patent
          against the  infringement  by third parties.  Upon  termination of all
          proceedings  involving such claims or  allegations,  Allegiance  shall
          remit the balance, if any, of the payments accrued but not yet paid to
          Isolyser.  The monetary recovery,  if any, shall be shared by Isolyser
          and  Allegiance  in the same ratio as they have shared the expenses of
          the Licensed Patent enforcement.

point.  Allegiance  will use reasonable  efforts to purchase a [***] product mix

to lower the basis weight of surgical drapes to reduce isolyser's costs.  The
cost for purchase  exceeding [***] shall be subject to negotiation and agreement
between the parties.


          4.2.1. PRICE INCREASES

               Isolyser  will not  increase  its  prices  during the Term of the
          Agreement.

     4.3. ALLEGIANCE'S DUTIES

          4.3.1. PURCHASE EXISTING INVENTORY

               Allegiance agrees to purchase  Isolyser's  existing  inventory of
          Material  ("Isolyser  Inventory"),  which  inventory  is  described on
          Exhibit  4  hereto,  during  the  first  nine (9)  months of the Term.
          Allegiance  shall not be obligated to purchase  Isolyser  Inventory to
          the  extent  it has a cost to  Allegiance  in  excess  of two  million
          dollars  ($2,000,000).  Allegiance  will use  commercially  reasonable
          business  efforts  to  sell  the  Isolyser   Inventory  to  Allegiance
          customers  during  the first  nine  months of this  Agreement.  To the
          extent that  Allegiance  is not able to sell such  Isolyser  Inventory
          during this time  period,  Isolyser  agrees to  repurchase  any unsold
          Isolyser Inventory held by Allegiance 120 days after Allegiance begins
          to sell Products  under its own 510(k).  Isolyser  shall purchase such
          remaining Isolyser Inventory from Allegiance at Allegiance's  original
          cost from  Isolyser as  specified in Exhibit 4.  Purchases  under this
          Section  4.3.1 are not credited  against the  obligation of Allegiance
          under Section 4.3.2.

          4.3.2. REQUIREMENTS AND MINIMUM PURCHASE AMOUNT

               Allegiance  shall  purchase its  requirements  for a  dissolvable
          material  made from PVA for use in the  healthcare  field  solely from
          Isolyser  during  the Term and any  extended  term of this  Agreement.
          Allegiance's  requirements  shall include a minimum of [***] ("Minimum
          Purchase Amount") during the Term of this Agreement; provided Isolyser
          has not  materially  breached  this  Agreement.  Isolyser will seek to
          obtain  the  dissolution  approvals  specified  in  Exhibit 7 within 9
          months of the Effective Date (18 months in the case of Japan).  If any
          of the pending  approvals are not obtained with such time frames,  the
          Minimum  Purchase  Amount  will be reduced  by three  times the amount
          specified  for each  applicable  pending  approval.  If any  potential
          customer of Allegiance would have to pay an extra fee or surcharge for
          disposal of the Products  because of the  composition of the Products,
          the Minimum Purchase Amount shall be reduced by a reasonable  estimate
          of the total sales  amount for  Products  that could have been sold to
          each such customer.  In addition, if Isolyser or any of its Affiliates
          shall fail to perform in any material manner any of its obligations to
          any of Allegiances  customers with respect to the disposal of Products
          or if any disposal  facilities  operated or managed by Isolyser or any
          of its  Affiliates  shall  fail in any  material  manner to operate at
          anticipated  levels, then the Minimum Purchase Amount shall be reduced
          by an amount equal to the estimated  "normal" purchases of Products by
          the affected customer minus the actual purchases by such customer. Any
          ORE(R)  Products  included as a component of any  kits/packs  shall be
          credited toward the Minimum Purchase  Amount.  In the event Allegiance
          purchases  less than the  Minimum  Purchase  Amount,  Isolyser's  sole
          remedy  shall be to convert  this  Supply and License  Agreement  to a
          nonexclusive agreement.

          4.3.3. SUBMIT ORDERS

               Allegiance  shall  submit  its orders  for the  Minimum  Purchase
          Amount of Materials  during the Term of this Agreement on its standard
          purchase order form, a copy of which is attached  hereto as Exhibit 5,

          of the Materials in accordance with Material  information  provided by
          Isolyser.

          that will assist  Allegiance  in obtaining  any  necessary  regulatory
          approval  required by Allegiance to sell the Products or to support an
          advertising or similar challenge to marketing claims; and

          4.4.7. 510(K) SUPPORT

          for Allegiance to file its own 510(k)  application or applications for

     Any written or verbal  information which either party provides to the other
and  identifies  as  "confidential"  will be held in confidence by the receiving
party  and  will  not be  used  for  any  purpose  other  than  to  further  the
relationship   between  the  parties   under  this   Agreement.   The  foregoing
confidentiality   obligation   shall  not  apply  if  the  receiving  party  can
demonstrate that such information:  (i) was, at the time of disclosure to it, in
the public  domain;  (ii) after  disclosure  to it, is  published  or  otherwise

          Product or allegedly caused by Isolyser's  manufacture,  or the use or
          disposal of any Material or Product, except to the extent any personal

          misrepresentation    by   Allegiance    concerning    the   Material's

          packaged,  labeled or held solely in order to  determine  whether said
          Materials  are  being  manufactured,  packaged,  labeled  or  held  in
          conformity   with  the  terms  of  this   Agreement,   (provided  such
          representative executes an appropriate  confidentiality  agreement and
          visits  during  normal  business  hours after  reasonable  notice) and
          further  agrees to provide  Allegiance  with such  documents as it may
          reasonably  require  to  determine  whether  the  Materials  are being
          manufactured,  packaged,  labeled  or  held  in  accordance  with  the
          provisions of this Agreement.

          negotiations  in the  spirit of mutual  cooperation  between  business
          executives with authority to resolve the controversy. Each party shall
          designate  an employee who will be the initial  contact for  resolving
          disputes.  Each party shall raise any questions,  claim or controversy
          with the  designated  employee  of the  other  party.  The  designated
          employees will work together to resolve the relevant issue in a manner
          that  meets  the  interests  of both  parties,  or until  the issue is
          referred to  designated  officers of the parties as set forth below in
          this Section 5.6.1. The employees  initially  designated by each party
          for purposes of this Section are as follows:

                  ISOLYSER:         Migo Nalbantyan

                  ALLEGIANCE:       Mike Hudson






               The parties may change such  designation by giving notice of such
          change  pursuant to Section 5.5 of this  Agreement.  If the designated
          employees  are unable to resolve  any claim or  controversy,  prior to
          taking  action as provided in Section  5.6.2,  the parties shall first
          submit such claim or controversy to the appropriate general counsel or
          appropriate legal representative of each party for resolution,  and if
          such general counsel or appropriate legal representative are unable to
          resolve such claim or controversy, either party may request that their
          respective chief executive  officers,  or their  respective  delegees,
          attempt to resolve the  dispute.  The officers or delegees to whom any
          such claim or controversy is submitted as provided above shall attempt
          to  resolve  the  dispute  through  good  faith  negotiations  over  a
          reasonable  period,  not to  exceed  30 days in the  aggregate  unless
          otherwise  agreed.  Such 30 day period  shall be deemed to commence on
          the date of a notice from either party describing the particular claim
          or controversy.

          5.6.2. ARBITRATION

               Any  dispute  that is not  resolved by  negotiations  pursuant to
          Section  5.6.1 will,  upon the  written  request of either  party,  be
          resolved by binding arbitration  administered by American  Arbitration
          Association in accordance with the Commercial Arbitration Rules of the
          American  Arbitration  Association by a panel of three arbitrators who
          are qualified in the field of  healthcare  products.  Such  arbitrator
          shall  determine  a  schedule  for   determination  of  such  dispute,
          establish  the scope of discovery and establish the length of hearings
          that is reasonable  under the  circumstances.  Such  arbitrator  shall
          determine  the  dispute  in  accordance  with this  Agreement  and the
          substantive  rules of law and the  rules  regarding  admissibility  of
          evidence (but not the rules of  procedure)  that would be applied by a
          federal court sitting in Illinois. The arbitration shall take place in
          Nashville,  Tennessee.  Notwithstanding  any  choice of law  provision
          included  in this  Agreement,  the United  States  Arbitration  Act, 9
          U.S.C.  Sections 1-16 shall govern the  interpretation and enforcement
          of this arbitration provision. Judgment upon the award rendered by the
          arbitrator may be entered by any court having jurisdiction. Where this
          Agreement  provides for future  agreement  by the parties,  failure to
          reach such  agreement  shall not  constitute a dispute  subject to the
          provisions  of  this  Section  5.6.2  except  as  expressly   provided
          otherwise.

          5.6.3. INJUNCTIVE RELIEF

               Either party may,  without  inconsistency  with this Section 5.6,
          apply to any court having  jurisdiction  hereof and seek  provisional,
          injunctive or other  equitable  relief as necessary to prevent serious
          and  irreparable  injury  to such  party  or to  others.  The  parties
          acknowledge  that this  contract  evidences  a  transaction  involving
          interstate  commerce.  The use of arbitration  procedures  will not be
          construed  under the doctrine of laches,  waiver or estoppel to affect
          adversely either party's right to assert any claim or defense.




     5.7 FORCE MAJEURE

     If performance by either party (the  "Performing  Party") of any service or
obligation under this Agreement is prevented,  restricted, delayed or interfered
with by reason  of labor  disputes,  strikes,  acts of God,  floods,  lightning,
severe  weather,  shortages of  materials,  rationing  utility or  communication
failures,  failure or delay in  receiving  electronic  data,  earthquakes,  war,
revolution,  civil commotion, acts of public enemies, blockade,  embargo, or any
law, order, proclamation,  regulation,  ordinance,  demand or requirement having
legal effect of any government or any judicial  authority or  representative  of
any such government, or any other act or omission whatsoever, whether similar or
dissimilar to those referred to in this clause,  which are beyond the reasonable
control of such Performing  Party,  then such Performing  Party shall be excused
from such  performance  to the extent  that (i) such  cause,  and the  resulting
prevention,  restriction,  delay or  interference,  were  beyond the  reasonable
control  of such  Performing  Party;  and (ii) such  Performing  Party  took all
reasonable  steps  to  prevent  and  mitigate  such  cause,  and  the  resulting
prevention,  restriction, delay or interference.  Notwithstanding the foregoing,
if any prevention,  restriction, delay or interference under this Section 5.7 of
any material  service or obligation of Isolyser  continues for at least 60 days,
then  Allegiance by written  notice to Isolyser may  terminate  its  obligations
under Section 4.3.2 without further obligation.






     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be
executed  by their duly  authorized  officers  on the day and due first  written
above.
