         InMedica  is a  medical  products  research  and  development  company.
Through  its  subsidiary,  MicroCor,  it has  developed  a method for  measuring
hematocrit  non-invasively  (without  drawing  blood)  and has  applied  for and
received  four (4) patents  from the U.S.  Patent and  Trademark  Office.  As of
December 12, 1995,  MicroCor's  application  for a patent  entitled  "Method and
Apparatus for  Non-Invasively  Determining  Hematocrit"  was allowed by the U.S.
Patent and Trademark Office,  and such patent issued on June 18, 1996, as Patent
No.  5,526,808 with a term of 17 years and an expiration  date of June 18, 2013.
MicroCor has been issued three additional patents, Patent No. 5,642,734,  Patent
No.  6,128,518  and Patent No.  6,766,191,  each of which claims  priority  from
October 4, 1990, the date of the first patent's filing, and each of which has an
expiration date of October 4, 2010.

         Pursuant to a Development,  Licensing and Manufacturing Agreement dated
May 10, 2001 (the "2001  Agreement"),  Chi Lin and InMedica  pursued  additional
development  on  the  non-invasive   hematocrit  technology.   The  methods  and
procedures to measure hematocrit  non-invasively,  including without limitation,
the patents and technologies incorporated in the patents and patent applications
described above and the development work pursued by Chi Lin and/or InMedica, are
collectively referred to herein as the "Hematocrit Technology."

         InMedica  is  a  publicly  traded  corporation.  Chi  Lin  is  a  major
shareholder of InMedica,  owning one-third of the issued and outstanding  shares
of  InMedica's  common  stock.  MicroCor is a privately  held  corporation  with
5,000,000  shares of common stock (the "MicroCor  Stock")  authorized  under its
Articles  of  Incorporation  and no other  class or series of stock  authorized.
InMedica  and Chi  Lin  own all of the  issued  and  outstanding  shares  of the
MicroCor Stock (147,101  shares),  with InMedica owning 117,681 shares (80%) and
Chi Lin owning 29,420 shares (20%). In order to facilitate  further  development
of the Hematocrit  Technology described in this Agreement,  InMedica and Chi Lin
propose to  transfer,  assign,  or license  their  respective  interests  in the
Hematocrit Technology to MicroCor.

the exercise of the option  granted to Wescor is deemed to be at a price that is
too low.


                                    AGREEMENT

         In  consideration  of the  foregoing  recitals,  the  mutual  covenants
described  herein and other good and  valuable  consideration,  the  receipt and
sufficiency  of which are hereby  acknowledged,  the  parties,  intending  to be
legally bound, hereby agree as follows:

         1. Ownership and Licensing of Hematocrit Technology.

                  1.1  Transfer  of  Hematocrit   Technology.   InMedica  hereby
         transfers,  assigns and conveys to MicroCor all of its right, title and
         interest  in  and to  the  Hematocrit  Technology  and  any  derivative
         thereof,   including,   without   limitation,   ownership,   licensing,
         marketing,  sales, distribution and manufacturing rights. The foregoing
         transfer, assignment and conveyance is intended by the parties to cover
         all of the rights,  title and  interests of InMedica in the  Hematocrit
         Technology and any derivative  thereof,  whether such rights,  title or
         interests are held jointly or separately by InMedica,  and whether such
         rights, title or interests are in and to a part or whole of any element


                                       2


         of the Hematocrit  Technology.  The obligation of InMedica to transfer,
         assign and convey as described in this Section 1.1 shall  include,  but
         not be limited  to, the  obligation  to cause any  agents,  independent
         contractors and research partners (including Medical Physics, Inc., and
         Billings & Associates)  to transfer,  assign and convey to MicroCor any
         such  rights  in  the  Hematocrit   Technology,   including  rights  to
         government grants. The parties acknowledge and agree that no royalty or
         other  compensation  is due or payable  to  InMedica  arising  from the
         Hematocrit  Technology or any Product  developed  therefrom,  except as
         expressly  set  forth  herein in  Section  6.  Upon  execution  of this
         Agreement,  InMedica acknowledges and agrees that the 2001 Agreement is
         hereby  superceded  and  terminated  and  that all  obligations  of the
         parties thereunder have been performed, waived, fulfilled, or otherwise
         relieved.

                  1.2 License of Hematocrit Technology. Chi Lin hereby grants to
         MicroCor,   its  successors  and  assigns,  an  exclusive,   worldwide,
         royalty-free right and license (the "Chi Lin License") in and to all of
         its right,  title and interest in and to the Hematocrit  Technology and
         any derivative  thereof,  to make, have made, use, sell, offer to sell,
         and import  Products and to practice  methods covered by or included in
         the Hematocrit Technology for the life of any protectable rights in the
         Hematocrit  Technology.  MicroCor  shall have the right to  sublicense,
         assign or transfer  the Chi Lin License to third  parties.  The Chi Lin
         License is intended  by the parties to cover all of the rights,  title,
         and  interests  of  Chi  Lin  in  the  Hematocrit  Technology  and  any
         derivative thereof,  whether such rights,  title, or interests are held
         jointly or  separately by Chi Lin, and whether such rights,  title,  or
         interests  are in  and  to a  part  or  whole  of  any  element  of the
         Hematocrit  Technology.  Chi Lin agrees  that it shall take all actions
         reasonably necessary to maintain the rights included within the Chi Lin
         License and to diligently and vigorously defend and protect such rights
         from infringement,  improper use, depreciation,  or other loss of right
         due to the acts of third  parties or the public in general,  including,
         without limitation,  pursuing  appropriate patents and other applicable
         protections;  provided,  however,  that  any  and  all  reasonable  and
         appropriate  costs and expenses  incurred in the defense and protection
         of such rights, including but not limited to legal fees, shall be borne
         by MicroCor if Chi Lin obtains  MicroCor's prior written consent before
         incurring  any such  costs and  expenses,  which  consent  shall not be
         unreasonably  withheld  in view  of the  cost  involved  and in view of
         MicroCor's products, business and marketing practices, and business and
         marketing  plans.   Notwithstanding  the  foregoing,  Chi  Lin  has  no
         obligations  to take any action to protect or defend any right included
         within the Chi Lin  License if  MicroCor  does not  consent to bear the
         costs and expenses to be incurred in such defense and  protection.  Chi
         Lin further  agrees that it shall take no action,  with  respect to the
         rights included within the Chi Lin License,  that would have the effect
         of negatively impacting the right of MicroCor to use exclusively,  such
         rights.  In the event Chi Lin or MicroCor learns of any event,  any act
         of a third party, or any action or proceeding,  whether such event, act
         or action has occurred,  been  commenced or is being  threatened,  that
         would negatively  impact the rights included within the Chi Lin License
         (a  "Negative  Action"),  then such party  shall  give the other  party
         written  notice  of such  Negative  Action.  Chi Lin  agrees  to retain
         counsel  acceptable  to  MicroCor,   at  MicroCor's  expense  and  with
         MicroCor's prior written consent,  to take all reasonable and necessary
         steps to protect or defend  against such  Negative  Action.  If Chi Lin
         fails to retain  counsel  or to take  other  reasonable  and  necessary
         protective  and  defensive   actions  within  five  (5)  business  days
         following  the  date  MicroCor  delivers  written  notice  to  Chi  Lin
         requesting  such  actions,  MicroCor  shall have the right,  at its own
         expense,  to take such actions in the name of Chi Lin or in  MicroCor's


                                       3


         own  name,  as may  be  appropriate.  Nothing  herein  shall  authorize
         MicroCor  to settle such  Negative  Actions  without the prior  written
         consent of Chi Lin, if by any such  settlement  Chi Lin is obligated to
         make any monetary payment, to assume any other obligation, to part with
         any property or any interest therein,  to be subject to any injunction,
         or to grant  any  license  or any  right  included  within  the Chi Lin
         License.  Notwithstanding the foregoing,  Chi Lin has no obligations to
         take any action to protect or defend  against  any  Negative  Action if
         MicroCor does not consent to bear the costs and expenses to be incurred
         in such defense and  protection,  nor does Chi Lin have any obligations
         to take any  action to defend  against  any  action,  threat,  claim or
         proceeding  alleging  that the Products  have  infringed  any patent or
         other intellectual  property right of any third party due to any causes
         other  than  the  rights  included  within  the  Chi Lin  License.  The
         obligation of Chi Lin to license the rights included within the Chi Lin
         License shall  include,  but not be limited to, the obligation to cause
         any agents,  independent contractors,  and research partners (including
         Medical Physics,  Inc., and Billings & Associates) to similarly license
         to MicroCor any such rights. The parties acknowledge and agree that the
         rights included within the Chi Lin License do not include any rights in
         new  developments,  discoveries or other  intellectual  property rights
         developed or  discovered as a result of future work done by MicroCor or
         Chi Lin, their agents,  independent contractors,  and research partners
         after the execution of this Agreement pursuant to any government grants
         concerning the Hematocrit  Technology,  and that all such developments,
         discoveries and intellectual property rights shall be the sole property
         of MicroCor.  The rights included  within the Chi Lin License  include,
         without  limitation,  any rights  still  remaining  under any  licenses
         granted  to it under  the 2001  Agreement  to sell and  distribute  the
         Products  in  "Asia,"  as  defined  in  Section   6.2.4.   The  parties
         acknowledge  and agree that no royalty or other  compensation is due or
         payable  to Chi Lin  arising  from  the  Hematocrit  Technology  or any
         Product  developed  therefrom,  except as expressly set forth herein in
         Section 6. Upon execution of this Agreement,  Chi Lin  acknowledges and
         agrees that the 2001 Agreement is hereby  superceded and terminated and
         that all  obligations of the parties  thereunder  have been  performed,
         waived, fulfilled, or otherwise relieved.

         2. MicroCor  Finances and Capital  Structure.  InMedica  shall take all
reasonable  action, or cause MicroCor to take all reasonable  action, as soon as
is reasonably  practicable before or upon the execution of this Agreement to (i)
terminate any agreements,  resolve any disputes, pay any liabilities and perform
any  obligations of MicroCor  existing as of the time  immediately  prior to the
effectiveness  of this  Agreement  such that,  after the  transfer  described in
Section 1,  MicroCor's  only  assets  and  liabilities  shall be the  Hematocrit
Technology and the related rights and duties described in or reasonably  arising
from this  Agreement;  (ii) effect a  restructuring  and split of the issued and
outstanding  shares  of the  MicroCor  Stock  so  that  immediately  after  such
restructuring  and split  the  total  outstanding  shares  of  MicroCor  will be
2,500,000  shares  with  InMedica  owning  2,000,000  shares  and Chi Lin owning
500,000  shares  of the  MicroCor  Stock;  and  (iii)  recall  all  certificates
representing  issued and  outstanding  shares of MicroCor Stock and re-issue new
certificates to the holders of such shares in the new share amounts described in
the  preceding  clause (ii) and include on such new  certificates  a conspicuous
reference to the existence of this  Agreement and the fact that it restricts the
transfer of the shares and affects the management of MicroCor.  All certificates
representing  shares  of the  MicroCor  Stock  issued  during  the  term of this


                                       4


Agreement  shall  include  a  conspicuous  reference  to the  existence  of this
Agreement  and the fact that it restricts the transfer of the shares and affects
the management of MicroCor.  Chi Lin shall reasonably cooperate with InMedica to
the extent necessary to accomplish the purposes described in this Section.

         3. Stock Restrictions. During the term of this Agreement:

                  3.1. Transfers Prohibited. Without obtaining the prior written
         consent of all parties  hereto,  each of  InMedica,  Chi Lin and Wescor
         shall   be   prohibited   from   transferring,   conveying,   pledging,
         hypothecating or otherwise assigning, and each of InMedica, Chi Lin and
         Wescor  hereby  covenants  and  warrants  that it shall  not  transfer,
         convey, pledge, hypothecate or otherwise assign, any part or all of its
         interest  in any  shares of the  MicroCor  Stock,  whether  now held or
         hereafter  acquired,  to or for the benefit of any party or third party
         except as expressly provided herein. The provisions of this Section are
         subject to the provisions of Section 3.4.

                  3.2.  Newly  Authorized  or Issued Stock  Prohibited.  Without
         obtaining the prior  written  consent of all parties  hereto,  MicroCor
         shall be prohibited  from  authorizing or issuing,  and MicroCor hereby
         covenants and warrants that it shall not authorize or issue, any shares
         of  MicroCor  Stock or any  shares of any other  class or series of the
         capital  stock of  MicroCor to or for the benefit of any party or third
         party except as expressly provided herein.

                  3.3.  MicroCor  Board  Composition.  During  the  term of this
         Agreement, regardless of the number of shares of MicroCor Stock held by
         the  parties,  the Board of  Directors  of  MicroCor  shall  consist of
         exactly  five (5)  directors,  three  (3) of whom  shall be  chosen  by
         InMedica, one (1) of whom shall be chosen by Chi Lin, and the remaining
         one (1)  director  shall be chosen  by  Wescor.  InMedica,  Chi Lin and
         Wescor  shall  take  all  necessary  action,  in  their  capacities  as
         shareholders  of MicroCor,  to accomplish  the foregoing  provisions of
         this Section.  Only upon the written  consent of InMedica,  Chi Lin and
         Wescor, may the size or composition of MicroCor's Board of Directors be
         changed during the term of this Agreement.

                  3.4.  Right of First  Refusal.  The provisions of this Section
         3.4 shall apply in the event the parties have received an offer for the
         acquisition  of MicroCor  that  InMedica and Chi Lin have  approved and
         intend to accept (an "Acquisition Offer"). An Acquisition Offer must be
         a bona fide offer from a qualified  third party to (i)  purchase all of
         the outstanding  MicroCor Stock, (ii) purchase all or substantially all
         the assets of MicroCor,  or (iii) merge or otherwise  combine  MicroCor
         with one or more entities upon the consummation of which the holders of
         MicroCor  Stock  immediately  prior thereto would hold less than 50% of
         the  shares of the voting  stock or other  ownership  interests  in the
         surviving  entity.  The  value  equivalent  in the case of a merger  or
         combination or where the  consideration is other than cash as set forth
         in the  Acquisition  Offer  must be  supported  by a  fairness  opinion
         rendered by a recognized business valuation expert. Upon the receipt of
         an  Acquisition  Offer,  InMedica and Chi Lin shall give Wescor written
         notice (the "Acquisition  Offer Notice") thereof and of their intent to
         accept the Acquisition Offer.  InMedica and Chi Lin hereby grant Wescor
         a right of first  refusal (the "First  Refusal  Right") to purchase all
         (but not less than all) of the MicroCor Stock held by both InMedica and
         Chi  Lin.  Any  First  Refusal  Right  shall  exist  from  the date the


                                       5


         Acquisition  Offer Notice is delivered to Wescor and shall expire sixty
         (60) days thereafter.  To exercise a First Refusal Right, Wescor shall,
         prior to its expiration,  give InMedica and Chi Lin written notice (the
         "Exercise  Notice") of Wescor's  intent to exercise  the First  Refusal
         Right. The terms of such First Refusal Right shall be as follows:

                           3.4.1.   Purchase   Price.   The  purchase  price  of
                  InMedica's  and Chi Lin's  MicroCor  Stock shall be calculated
                  as: (x) the total  number of shares of MicroCor  Stock held by
                  InMedica   and  Chi  Lin  divided  by  the  total   number  of
                  outstanding  shares of MicroCor  Stock,  (y) multiplied by the
                  purchase  price  (or its  value  equivalent  in the  case of a
                  merger or combination or where the consideration is other than
                  cash) set forth in the  Acquisition  Offer,  (z) multiplied by
                  90%.

                           3.4.2.  Purchase  Terms.  Terms  for  payment  of the
                  purchase  price  shall be, at  Wescor's  option,  either:  (i)
                  twenty percent (20%) of the purchase price paid within 60 days
                  following the delivery of the Exercise Notice, and the balance
                  paid  in  equal  monthly  payments  over  twelve  (12)  months
                  (beginning  one month  following the 20%  payment),  with such
                  balance bearing interest at an annual rate of two percent (2%)
                  plus the Prime Rate;  or (ii)  payment  terms that are no less
                  favorable  to InMedica  and Chi Lin than they would be for the
                  acquirer  as set forth in the  Acquisition  Offer.  As used in
                  this  Agreement,  the term "Prime  Rate" shall mean the "prime
                  rate" as  reported  in the  Wall  Street  Journal  on the date
                  closest to the date the installment payments begin.

                           3.4.3. Merger  Alternative.  As an alternative to the
                  payment of the purchase  price,  InMedica,  Chi Lin and Wescor
                  agree to  negotiate  in good  faith to attempt to agree upon a
                  merger of InMedica, MicroCor and Wescor. In such a merger, the
                  value  attributed to MicroCor  shall be the purchase price (or
                  value equivalent) in the Acquisition Offer without reducing by
                  multiplying  by 90% as  described  in  clause  (z) of  Section
                  3.4.1; the respective values attributed to InMedica and Wescor
                  shall be  established  by a  fairness  opinion  rendered  by a
                  recognized  business  valuation expert, as to whom none of the
                  parties has a reasonable objection.

                           3.4.4.  Agreement Terminated.  In the event the First
                  Refusal Right is exercised, this Agreement shall be terminated
                  except  for the  royalty  provisions  described  in Section 6,
                  which shall survive.

                  3.5 Disclosure of Potential Acquisition Transactions.  Each of
         InMedica, Chi Lin and Wescor covenant and agree that during the term of
         this  Agreement  if it intends to solicit an offer or if it receives an
         offer  or other  indication  of  interest  from a third  party  that is
         reasonably  likely to  develop  into a serious  offer or  agreement  to
         purchase or acquire a substantial  portion of the assets of MicroCor or
         of the  MicroCor  Stock,  or to  combine  or  merge  with  MicroCor  (a
         "Potential  Acquisition  Transaction"),  then it shall  give the  other
         parties  to this  Agreement  notice  of  such  solicitation,  offer  or
         interest as soon as is reasonably  possible and shall  continue to give


                                       6


         such  other  parties   notice  of  changes  or   developments   in  the
         negotiations  concerning such Potential Acquisition  Transaction.  Such
         notices  shall  include  details  as to the  terms  of  such  Potential
         Acquisition  Transactions.  The  parties  agree that if a party  hereto
         shall  fail to  give  the  notices  required  under  this  Section  the
         Potential Acquisition Transaction shall not be entered into without the
         written  consent of any party who did not receive the required  notice.
         The parties  acknowledge  that during the term of this  Agreement  each
         party is permitted to solicit offers from and  communicate  interest to
         third parties concerning Potential Acquisition  Transactions,  although
         the consummation of such transactions can only be accomplished pursuant
         to the express  terms set forth in other  sections  of this  Agreement.
         Nothing in this Section shall be  interpreted to give a party any right
         to  enter  into a  transaction  that is  otherwise  prohibited  by this
         Agreement.

         4. Wescor Purchase of MicroCor Stock.

                  4.1. From InMedica. InMedica hereby sells to Wescor and Wescor
         hereby  purchases from InMedica  300,000 shares of MicroCor  Stock.  As
         partial  consideration  for such  purchase  and sale,  Wescor shall pay
         InMedica  $300,000 as follows:  (i) $30,000 upon the  execution of this
         Agreement,  and (ii) 18 monthly payments of $15,000 with the first such
         monthly payment due and payable on the first day of the month following
         the Effective Date and each successive monthly payment due on the first
         day of each successive month until all 18 payments are made.

                  4.2.  From Chi Lin.  Chi Lin hereby sells to Wescor and Wescor
         hereby  purchases  from Chi Lin 75,000  shares of  MicroCor  Stock.  As

         Lin  $75,000  as  follows:  (i)  $7,500  upon  the  execution  of  this
         Agreement,  and (ii) 18 monthly  payments of $3,750 with the first such

         the Effective Date and each successive monthly payment due on the first
         day of each successive month until all 18 payments are made.

                  4.3.  Special  Provision  for  Repayment  of Loan to InMedica.
         InMedica  and  Wescor  acknowledge  and agree  that  Wescor  has loaned
         InMedica certain sums of money which remain  outstanding as of the date
         this  Agreement is executed (the "Wescor  Loans").  InMedica  shall pay
         Wescor 20% of each installment  payment  (including the initial payment
         due upon  execution)  due from Wescor to InMedica  under Section 4.1 as
         partial  performance of its repayment  obligations of the Wescor Loans.
         At InMedica's  election,  InMedica may direct Wescor to pay only 80% of
         each such installment payment in satisfaction of InMedica's  obligation
         under this Section.

         5.  Management of MicroCor;  Issuance of New Stock;  Options to Acquire
         Remainder of MicroCor.

                  5.1. Management Rights and Duties of Wescor. InMedica, Chi Lin
         and Wescor,  as the current and future  (pursuant  to the terms of this
         Agreement) majority shareholders of MicroCor, agree that upon execution
         of this  Agreement  Wescor shall assume the  management  of MicroCor as
         described in this Section 5.1.



                                       7


                           5.1.1. Rights and Duties. Wescor shall have the right
                  and  obligation  to  manage  the   day-to-day   operations  of
                  MicroCor,  including the hiring and firing of its officers and
                  employees  and   contracting   for  employees  or  independent
                  contractors.  Wescor  shall  use its  best  efforts  with  all
                  reasonable  speed and  efficiency to develop or cause MicroCor
                  to  develop  the  Products  as  described   herein.   Wescor's
                  obligation  to fund  the  expenses  of  MicroCor's  operations
                  ("Wescor Funding Obligations") shall be as follows: (i) Wescor
                  shall not be responsible for funding  expenses  related solely
                  to   manufacturing   or   sales   and   marketing   operations
                  ("Manufacturing  and  Sales  Expenses");  (ii)  except  to the
                  extent   that   expenses   are   reasonably    includable   as
                  Manufacturing and Sales Expenses,  Wescor shall be responsible
                  for and shall  contribute  funds to MicroCor  to pay  expenses
                  incurred by  MicroCor  for  research  and  development  of the
                  Products  ("R&D  Expenses"),  including,  but not  limited to,
                  costs  related to  development  of the  Prototype  (as defined
                  below),  costs  related to obtaining FDA Clearance (as defined
                  below),  and R&D  Expenses  related  to First  Production  (as
                  defined  below).  Notwithstanding  the fact that Wescor has no
                  obligation to fund  Manufacturing  and Sales Expenses,  Wescor
                  agrees to exercise its commercially reasonable best efforts to
                  arrange  for the  financing  of the  Manufacturing  and  Sales
                  Expenses and of any royalty payment  obligations under Section
                  6 ("Wescor Financing Commitment"),  subject to approval of the
                  Board of MicroCor. In arranging for any such financing, Wescor
                  shall  not  be  obligated  to  loan  any  funds  itself  or to
                  separately guarantee or provide separate security for any such
                  loans which are arranged for MicroCor by Wescor.

                           5.1.2. Board Authority. MicroCor's Board reserves the
                  authority to approve or disapprove  actions by MicroCor (or by
                  Wescor on  MicroCor's  behalf)  (i) to  acquire  or dispose of
                  capital  assets,  or to incur capital  expenditures or debt if
                  such actions would involve in the aggregate  more than $20,000
                  during any  12-month  period;  (ii) to  contract  with a third
                  party to perform part or all of the  manufacturing,  marketing
                  and selling  functions  necessary to accomplish  the intent of
                  this  Agreement;  or  (iii)  to  assign,  transfer,   license,
                  sub-license,  pledge as collateral,  mortgage,  hypothecate or
                  otherwise encumber part or all of the Hematocrit Technology or
                  any other intellectual  property interest owned by or licensed
                  to MicroCor.  MicroCor (or Wescor on MicroCor's  behalf) shall
                  not  take  any  action  described  in the  preceding  sentence
                  without first  delivering  to all members of MicroCor's  Board
                  written notice of its intent to take such action.  If no Board
                  member objects within fifteen (15) business days of receipt of
                  such notice by delivering a written  notice to Wescor,  Wescor
                  may proceed to take such action.  If a Board  member  objects,
                  Wescor  shall not take such  action  until after the Board has
                  acted to  determine  whether  to consent  to such  action.  In
                  addition to other forms of notice permitted by this Agreement,
                  the  giving  of  notices  and   communicating   of  objections
                  described  in this  Section may be  accomplished  by facsimile
                  machine   transmission  or  by  email  if  a  confirmation  of
                  successful delivery or transmission is received by the sender.

                           5.1.3.  Termination  of  Management  Duties.  If  not
                  earlier  terminated  hereunder,  if (i) no Prototype  has been
                  completed  (as defined and  described  in Section  5.2) by the
                  date that is twelve (12) months  following the Effective Date,
                  (ii) no FDA  Clearance  (as described in Section 5.3) has been
                  received  by the date that is eighteen  (18) months  following
                  the  Effective  Date  (subject to the extension of such period
                  pursuant  to  Section  5.3),  (iii)  there  has  been no First
                  Production  (as defined in Section  5.4.1) of a Product by the
                  date that is twenty four (24) months  following  the Effective
                  Date  (subject to the  extension  of such  period  pursuant to
                  Section  5.3),  or (iv)  Wescor has not  fulfilled  the Wescor
                  Funding  Obligations  within a reasonable period following the
                  date such  obligations  become due from time to time, then the
                  Board of Directors of MicroCor  shall have the right to review
                  Wescor's  actions  in  fulfilling  its  obligations  to manage
                  MicroCor, and shall have the right to make such changes in the
                  management as it deems  appropriate.  The parties  acknowledge
                  and agree that such  changes  may, in the Board's  discretion,
                  include termination of this Agreement, in which case the Board
                  of Directors of MicroCor  shall  thereafter  have complete and
                  autonomous  control  over the  management  and  operations  of
                  MicroCor.  The parties  further  acknowledge  and agree that a
                  failure  by  Wescor  to comply  with its  covenants  under the
                  Wescor  Financing  Commitment  may result in MicroCor's  Board
                  assuming  the  rights  and  duties  pertaining  to the  Wescor
                  Financing  Commitment  and  terminating  Wescor's  rights  and
                  duties thereunder.

                  5.2.   Development  of  FDA  Prototype;   Stock  Purchase  and
         Issuance.  Wescor shall use its best efforts with all reasonable  speed
         and efficiency to develop, or cause MicroCor to develop, a prototype or
         prototypes of the Product(s) (the "Prototype")  suitable for conducting
         the  clinical  trials  necessary  to  prepare  for  submission  or  the
         Product(s) to the FDA for  regulatory  review and marketing  clearance.
         Upon such completion of the Prototype,  MicroCor shall issue to Wescor,
         500,000 new shares of MicroCor Stock. The  consideration for the shares
         issued to Wescor shall be the amounts  contributed  to MicroCor to fund
         the Wescor  Funding  Obligations  incurred to the date of completion of
         the  Prototype.  Such shares shall be deemed fully paid and not subject
         to any assessment.

                  5.3. FDA Clearance. Wescor shall use its best efforts with all
         reasonable  speed and  efficiency  to conduct  and  complete,  or cause
         MicroCor  to conduct  and  complete,  such  actions  as are  reasonably
         necessary  to gather data and prepare a 510(k)  Premarket  Notification
         submission  to the  FDA  covering  the  Product(s)  and to  obtain  the
         necessary  clearances  from the FDA to market  such  Product(s)  in the
         United States market ("FDA  Clearance").  In the event MicroCor's Board
         of  Directors  determines  that  Wescor  has acted in good faith in the
         performance  of its  obligations  to obtain FDA  Clearance but such FDA
         Clearance  has not been  obtained,  and the Board of Directors  further
         determines  that it is reasonable to expect that FDA Clearance  will be
         obtained in the future,  the Board of Directors  may extend for six (6)
         months the period  described  in clause  (ii) of Section  5.1.3,  which
         extension  would also  automatically  extend the  period  described  in
         clause (iii).  Upon subsequent  identical  determinations by MicroCor's
         Board of Directors,  additional  six-month extensions may be granted in
         the Board's discretion.



                                       9


                           5.3.1. Stock Issuance.  Upon obtaining FDA Clearance,
                  MicroCor shall issue to Wescor, 500,000 new shares of MicroCor
                  Stock. The consideration for the shares issued to Wescor shall
                  be the  amounts  contributed  to  MicroCor  to fund the Wescor
                  Funding  Obligations  incurred  to the date of  obtaining  FDA
                  Clearance.  Such  shares  shall be deemed  fully  paid and not
                  subject to any assessment.

                           5.3.2.  Option and Trump  Option to Acquire  MicroCor
                  Stock.  Upon  obtaining FDA  Clearance,  Wescor shall have the
                  option (the  "Option") to purchase all (but not less than all)
                  of the MicroCor Stock held by InMedica and Chi Lin pursuant to
                  the provisions of this Section 5.3.2. To exercise the Option:

                                    a. Notice.  Wescor  shall  deliver a written
                           notice  (the  "Option  Notice")  of its  election  to
                           exercise  the  Option  to both  InMedica  and Chi Lin
                           within  ninety  (90) days  following  receipt  of the
                           first   formal   notice  of  FDA   Clearance  of  the
                           Product(s).

                                    b. Purchase Price.  The purchase price under
                           the Option shall be the pro rata portion of the total
                           value of MicroCor attributable to the total shares of
                           MicroCor  Stock  held  by  InMedica  and  Chi Lin (as
                           compared to the total outstanding  shares of MicroCor
                           Stock).  The value of MicroCor (the "MicroCor  Option
                           Value") shall be  determined  as follows:  (i) Wescor
                           may choose to pay for and obtain an  appraisal of the
                           value (the "Option Appraisal Value") of MicroCor from
                           a nationally  recognized  appraisal  firm, as to whom
                           neither  InMedica  nor  Chi  Lin  have  a  reasonable
                           objection,  and the MicroCor Option Value shall equal
                           the Option Appraisal Value multiplied by 90%; or (ii)
                           Wescor may suggest a  reasonable  value for  MicroCor
                           (the  "Option  Suggested  Value"),  and the  MicroCor
                           Option Value shall equal the Option  Suggested  Value
                           (not multiplied by 90%). Wescor shall,  within thirty
                           (30)  days  following  the  delivery  of  the  Option
                           Notice,  deliver  to  InMedica  and Chi  Lin  written
                           notice (the  "Option  Value  Notice") of the MicroCor
                           Option  Value and all reports  and data that  support
                           its  determination  of such value.  InMedica  and Chi
                           Lin, at their expense, shall have the right to obtain
                           a  fairness  opinion  ("Fairness   Opinion")  from  a
                           recognized  business  valuation  expert  as  to  whom
                           Wescor has no  reasonable  objection  concerning  the
                           Option Appraisal Value or the Option Suggested Value,
                           as appropriate.  If the Fairness  Opinion  determines
                           that either the Option  Appraisal Value or the Option
                           Suggested Value, as applicable,  is not within a fair
                           range of value,  the Option shall  terminate.  In the
                           event the  Option is  exercised,  any  holders of the
                           MicroCor  Stock other than  InMedica and Chi Lin, who
                           have obtained  MicroCor shares in compliance with the
                           provisions  of Section  3.1,  shall have the right to
                           require  Wescor to purchase  their  MicroCor Stock at
                           the same pro rata price per share.

                                    c. Trump  Option.  Notwithstanding  Wescor's


                                       10


                           right to  exercise  the Option,  upon  receipt of the
                           Option  Value  Notice,  or, if a Fairness  Opinion is
                           obtained,  upon  receipt of a Fairness  Opinion  that
                           does not terminate  the Option,  InMedica and Chi Lin
                           jointly,  or  InMedica  by itself (but not Chi Lin by
                           itself)  shall  then  have  the  option  (the  "Trump
                           Option") to terminate  Wescor's  Option by purchasing
                           all (but not less  than  all) of the  MicroCor  Stock
                           held by Wescor. To exercise the Trump Option,  either
                           InMedica  or  InMedica  and Chi Lin  together,  shall
                           deliver a written notice (the "Trump Option  Notice")
                           to  Wescor  within  thirty  (30) days  following  the
                           receipt of the Option  Value  Notice.  In the event a
                           Fairness Opinion is being obtained, the period during
                           which a Trump Option Notice may be given shall extend
                           to  thirty  (30)  days  following   receipt  of  such
                           Fairness Opinion.  The purchase price under the Trump
                           Option  shall be the pro rata  portion  of the  total
                           value of MicroCor attributable to the total shares of
                           MicroCor  Stock  held by Wescor (as  compared  to the
                           total  outstanding  shares of  MicroCor  Stock).  The
                           total  value of  MicroCor  for  purposes of the Trump
                           Option shall be 110% of the Option Appraisal Value or
                           the Option  Suggested  Value, as appropriate,  as set
                           forth in Wescor's  Option Value Notice.  The purchase
                           price under the Trump  Option shall be paid to Wescor
                           as follows: 20% within thirty (30) days following the
                           delivery  of  the  Trump  Option   Notice,   and  the
                           remainder in equal monthly  installments of principle
                           and  interest  on the  first  day of each  successive
                           month for thirty six (36) months.  Interest  accruing
                           on such  remainder  shall be an annual  rate equal to
                           two percent  (2%) plus the Prime  Rate.  In the event
                           InMedica  and  Chi  Lin  exercise  the  Trump  Option
                           jointly,   they   shall   participate   in  the  same
                           proportions as their individual ownership of MicroCor
                           Stock bears to their aggregate  ownership of MicroCor
                           Stock.  If  the  Trump  Option  is  exercised,   this
                           Agreement shall then automatically terminate.

                                    d.  Option  Revival.   Notwithstanding   the
                           provisions of the preceding Paragraph c, Wescor shall
                           have the  right  to  revive  an  Option  (an  "Option
                           Revival")   terminated   by  the   Trump   Option  by
                           increasing by at least ten percent (10%) the purchase
                           price  provision  of the Option and  delivering a new
                           Option  Value  Notice to InMedica  and Chi Lin within
                           fifteen (15) days  following  the delivery of a Trump
                           Option  Notice.  Such new Option  Value  Notice shall
                           terminate the Trump  Option,  and shall be treated as
                           if it were an original Option Value Notice under this
                           Agreement. InMedica, or InMedica and Chi Lin jointly,
                           shall  again  have the  right to  exercise  the Trump
                           Option   pursuant  to   Paragraph  c,  based  on  the
                           increased  purchase price provision in the new Option
                           Value  Notice.  The Option,  Trump  Option and Option
                           Revival   may  be   repeated  as  many  times  as  is
                           necessary.

                                    e. Option Payment  Terms.  If a Trump Option
                           Notice is not  delivered  within the time  allowed by
                           InMedica or by InMedica and Chi Lin, the Trump Option
                           shall  expire.  Wescor  shall  then be  obligated  to
                           exercise  the  Option by paying  the  purchase  price
                           under the Option as follows:  20% within  thirty (30)
                           days  following  the  deadline  for the Trump  Option
                           Notice,   and  the   remainder   in   equal   monthly


                                       11


                           installments  of principle  and interest on the first
                           day of each  successive  month  for  thirty  six (36)
                           months.  Interest accruing on such remainder shall be
                           an annual  rate  equal to two  percent  (2%) plus the
                           Prime Rate.

                                    f. Merger Alternative.  As an alternative to
                           the payment of the  purchase  price under the Option,
                           InMedica,  Chi Lin and Wescor  agree to  negotiate in
                           good  faith  to  attempt  to agree  upon a merger  of
                           InMedica,  MicroCor and Wescor. In such a merger, the
                           value  attributed to MicroCor shall be 100% of either
                           the Option  Appraisal  Value or the Option  Suggested
                           Value; the respective  values  attributed to InMedica
                           and Wescor shall be established by appraisals  from a
                           recognized  appraisal  firm,  as to whom  none of the
                           parties  has  a  reasonable  objection.  The  parties
                           acknowledge that InMedica shall have no obligation to
                           agree  to  a  merger  the  terms  of  which  are  not
                           determined to be fair pursuant to a fairness  opinion
                           from a  recognized  business  valuation  expert as to
                           whom none of the parties has a reasonable objection.

                                    g. Effect on Agreement. If the Option is not
                           exercised,  this  Agreement  shall  continue  in full
                           force and effect.  If the Option is  exercised,  this
                           Agreement shall be  automatically  terminated  except
                           for the  royalty  provisions  set forth in Section 6,
                           which shall  survive,  and the Board of  Directors of
                           MicroCor   shall   thereafter   have   complete   and
                           autonomous control over the management and operations
                           of MicroCor.

                  5.4. Product Launched in Market. After obtaining FDA Clearance
         of a Product,  Wescor shall use its best  efforts  with all  reasonable
         speed  and  efficiency  to  cause  MicroCor  to  begin   manufacturing,
         marketing  and selling such Product in the market.  The  manufacturing,
         marketing and selling  functions shall be the right and  responsibility
         of MicroCor,  which may, in the  discretion  of its Board of Directors,
         contract  with  third  parties  for  part or all of the  manufacturing,
         marketing and selling of the Products.

                           5.4.1.  Stock  Issuance.  Upon  the  first  completed
                  production  run  of  units  of  the  Products  for  which  FDA
                  Clearance has been received and upon preparation of such units
                  for sale (the  "First  Production"),  MicroCor  shall issue to
                  Wescor,   700,000   new   shares  of   MicroCor   Stock.   The
                  consideration  for the  shares  issued to Wescor  shall be the
                  amounts  contributed  to MicroCor  to fund the Wescor  Funding
                  Obligations incurred to the date of the First Production. Such
                  shares  shall be  deemed  fully  paid and not  subject  to any
                  assessment.

                           5.4.2.  Second  Option  and Trump  Option to  Acquire
                  MicroCor Stock. After the First Production and issuance of the
                  shares to Wescor pursuant to section 5.4.1 Wescor shall have a
                  second  option  (the  "Second  Option"),  subject to the Trump
                  Option,  pursuant  to the  same  terms as  described  above in
                  Section  5.3.2,   except  that  the  Second  Option  shall  be
                  triggered  by the  First  Production,  and the  Second  Option


                                       12


                  Notice shall be delivered  within  ninety (90) days  following
                  the date of the First Production.

                           5.4.3.  Termination  of  Management.  Upon the  First
                  Production:  (i) Wescor's  rights and duties under Section 5.1
                  to manage MicroCor,  including the Wescor Funding  Obligations
                  and the  Wescor  Financing  Obligations,  shall  automatically
                  terminate,  (ii)  MicroCor  shall  operate  as  a  stand-alone
                  company  subject  to the  autonomous  control  of its Board of
                  Directors,  and (iii) the size and  composition  of MicroCor's
                  Board of Directors shall thereafter be determined  pursuant to
                  applicable  corporate  law,  provided that the parties to this
                  Agreement hereby agree that shareholders  shall have the right
                  to vote their shares  cumulatively in subsequent  elections of
                  MicroCor's  Board of Directors.  InMedica,  Chi Lin and Wescor
                  shall  take  all  necessary  action,  in their  capacities  as
                  shareholders   of  MicroCor,   to  accomplish   the  foregoing
                  provision of this Section.

         6. Grant of Royalties.

                  6.1. Minimum Royalty.  MicroCor hereby grants and shall pay to
         InMedica and Chi Lin a minimum annual  royalty (the "Minimum  Royalty")
         as defined and divided  below in Sections  6.1.1 and 6.1.2 as a minimum
         amount  until the Revenue  Royalty (as defined in Section  6.2) reaches
         the amounts described below.

                           6.1.1.  InMedica  Minimum  Royalty.  MicroCor  hereby
                  grants to  InMedica  a portion  of the  Minimum  Royalty  (the
                  "InMedica  Minimum  Royalty").  The InMedica  Minimum  Royalty
                  shall be in the amount of $160,000 per year, but shall be paid
                  in equal monthly royalty payments, with the first such monthly
                  royalty  payment  beginning  and first due on the date that is
                  eighteen  (18)  months   following  the  Effective  Date.  The
                  InMedica Minimum Royalty shall have the same term of existence
                  as the Revenue  Royalty (as defined in Section 6.2), and shall
                  terminate  on the same date the  Revenue  Royalty  terminates.
                  InMedica  shall pay  Wescor 20% of each such  monthly  royalty
                  payment due under this Section 6.1.1 as partial performance of
                  its repayment  obligations of the Wescor Loans until such time
                  as the Wescor Loans are fully repaid. At InMedica's  election,
                  InMedica  may  direct  Wescor  to pay  only  80% of each  such
                  monthly  royalty  payment with the remaining 20% thereof being
                  credited against InMedica's obligation under the Wescor Loans.

                           6.1.2.  Chi  Lin  Minimum  Royalty.  MicroCor  hereby
                  grants to Chi Lin the remaining portion of the Minimum Royalty
                  (the "Chi Lin Minimum  Royalty").  The Chi Lin Minimum Royalty
                  shall be in the amount of $40,000 per year,  but shall be paid
                  in equal monthly royalty payments, with the first such monthly
                  royalty  payment  beginning  and first due on the date that is
                  eighteen (18) months following the Effective Date. The Chi Lin
                  Minimum  Royalty  shall have the same term of existence as the
                  Revenue  Royalty  (as  defined  in  Section  6.2),  and  shall
                  terminate on the same date the Revenue Royalty terminates.



                                       13


                  6.2. Revenue Royalty.  MicroCor hereby grants and shall pay to
         InMedica and Chi Lin an annual royalty (the "Revenue Royalty") based on
         "Revenues"  (as defined in Section  6.2.1) as divided in Sections 6.2.3
         and 6.2.4. The Revenue Royalty shall be effective immediately and shall
         continue  for all  Revenues  received  or  accrued  through  the latest
         expiration  date  of  the  currently   existing  U.S.  Patents  on  the
         Hematocrit Technology,  which the parties acknowledge and agree include
         the following U.S.  Patents with the following  expiration  dates:  (i)
         Patent No. 5,526,808  expiring June 18, 2013, (ii) Patent No. 5,642,734
         expiring October 4, 2010,  (iii) Patent No. 6,128,518  expiring October
         4, 2010, and (iv) Patent No. 6,766,191 expiring October 4, 2010.

                           6.2.1 Revenues Defined. "Revenues" shall mean the sum
                  of  (i)  Royalty  Revenues,   and  (ii)  Sales  and  Licensing
                  Revenues.

                                    a.  Royalty  Revenues.   "Royalty  Revenues"
                           shall mean  payments  received  by  MicroCor  and its
                           assignees  and  successors in the nature of royalties
                           from licensees, sub-licensees and other third-parties
                           ("Third-Party  Licensees")  based  on  sales or other
                           dispositions by Third-Party  Licensees of Products or
                           any other goods or services incorporating any portion
                           of the Hematocrit Technology.

                                    b. Sales and Licensing Revenues.  "Sales and
                           Licensing  Revenues" shall mean revenues  received by
                           MicroCor and its  assignees and  successors  that are
                           (i)  net  sales  revenues  from  the  sale  or  other
                           disposition  of all  Products  or any other  goods or
                           services  incorporating any portion of the Hematocrit
                           Technology,  (ii)  revenues from the licensing of any
                           portion of the Products or the Hematocrit  Technology
                           (where such revenues are not Royalty  Revenues),  and
                           (iii)  any  other  revenues  (but  excluding  Royalty
                           Revenues)  generated by the Products,  the Hematocrit
                           Technology,  or any right or  interest  therein.  Net
                           sales revenues, as a component of Sales and Licensing
                           Revenues,  shall be the invoice price of all Products
                           sold less (i) standard  trade  discounts  and returns
                           actually allowed, (ii) all sales commissions or sales
                           discounts actually allowed, (iii) taxes applicable to
                           such sales, and (iv) shipping charges which are to be
                           paid by MicroCor or its assignees or  successors  and
                           not separately  invoiced.  Revenue from only one arms
                           length sale of the same  Product unit may be included
                           in Sales and Licensing Revenues,  and, in cases where
                           a  Product  unit is sold  more  than  once,  only the
                           revenue  from the first arms  length sale (the "First
                           Sale") of such Product unit will be included in Sales
                           and Licensing Revenues;  that is, revenue from a sale
                           of a Product  unit by a purchaser  of such unit shall
                           not be  included in Sales and  Licensing  Revenues if
                           the revenue from the sale of such Product unit to the
                           purchaser  (or to a prior  seller) has  already  been
                           included in Sales and Licensing Revenues. Further, if
                           the Product or use of the  Hematocrit  Technology  is
                           only a portion of a larger product or system, or if a
                           license is granted to include a Product or use of the
                           Hematocrit  Technology in a larger product or system,
                           then  only that  portion  of the  revenue  reasonably


                                       14


                           attributable to the Product or Hematocrit  Technology
                           (as  part of a  larger  product  or  system)  will be
                           included  in Sales and  Licensing  Revenues.  In such
                           instances   where  a  larger  product  or  system  is
                           involved,  the parties  may  further  agree as to the
                           portion of revenues  from such product or system that
                           is to be included in Sales and Licensing Revenues.

                           6.2.2 Calculation and Payment of Revenue Royalty. The
                  total Revenue Royalty payments payable by MicroCor,  including
                  both the InMedica Revenue Royalty (described in Section 6.2.3)
                  and the Chi Lin Revenue  Royalty  (described in Section 6.2.4)
                  (the  "Total  Revenue  Royalties"),  shall  be  calculated  as
                  follows:  The  sum of (i) in any  given  calendar  year,  four
                  percent (4%) of the first  $5,000,000  in Sales and  Licensing
                  Revenues,  three percent (3%) of Sales and Licensing  Revenues
                  in amounts exceeding $5,000,000 but not exceeding $20,000,000,
                  and two  percent  (2%) of  Sales  and  Licensing  Revenues  in
                  amounts exceeding  $20,000,000;  plus (ii) twenty five percent
                  (25%) of all Royalty Revenues.  Revenue Royalty payments shall
                  be paid by MicroCor  to InMedica  and/or Chi Lin by the end of
                  each month following the month in which there are any Revenues
                  to which the Revenue Royalty  applies.  In order to verify the
                  Revenues  described in this Section  6.2,  MicroCor  agrees to
                  make or cause the accounting books and records of MicroCor and
                  its assignees and successors available to InMedica and Chi Lin
                  or  to  their  agents,   including  independent  auditors,  in
                  reasonable form and at reasonable times and places.

                           6.2.3.  InMedica  Revenue  Royalty.  MicroCor  hereby
                  grants to  InMedica  a portion  of the  Revenue  Royalty  (the
                  "InMedica Revenue Royalty").  The InMedica Revenue Royalty for
                  any given  period  shall  equal the  Total  Revenue  Royalties
                  multiplied  by a  fraction,  the  numerator  of  which  is the
                  worldwide  Revenues  less the "Asian  Revenues" (as defined in
                  Section 6.2.4) for such period,  and the  denominator of which
                  is the  worldwide  Revenues  for  such  period.  The  InMedica
                  Revenue  Royalty  shall be  effective  immediately  and  shall
                  continue  for  all  non-Asian  Revenues  received  or  accrued
                  through  the date of  termination  of the  Revenue  Royalty as
                  described in Section 6.2 above.

                           6.2.4.  Chi  Lin  Revenue  Royalty.  MicroCor  hereby
                  grants to Chi Lin the remaining portion of the Revenue Royalty
                  (the "Chi Lin Revenue  Royalty").  The Chi Lin Revenue Royalty
                  for any given period shall equal the Total  Revenue  Royalties
                  multiplied by a fraction, the numerator of which is the "Asian
                  Revenues"  (as  defined  below)  for  such  period,   and  the
                  denominator  of  which  is the  worldwide  Revenues  for  such
                  period.  "Asian  Revenues"  shall  mean (i)  Royalty  Revenues
                  received  from a  Third-Party  Licensee  for  sales  or  other
                  dispositions  made by such Third-Party  Licensee in "Asia" (as
                  defined below), (ii) Sales and Licensing Revenues that are net
                  sales  revenues  from a First Sale made in Asia where,  at the
                  time of such First Sale, the seller does not  reasonably  know
                  that the ultimate  sale to the end user will be to a purchaser
                  outside of Asia,  (iii) Sales and Licensing  Revenues that are
                  net sales  revenues  from a First  Sale made  outside  of Asia
                  where,  at the time of such First Sale, the seller  reasonably
                  knows  that the  ultimate  sale to the end  user  will be to a


                                       15


                  purchaser  in Asia,  and (iv) any other  Sales  and  Licensing
                  Revenues  that are not net sales  revenues  that are  received
                  from a Third-Party  Licensee whose main office or headquarters
                  is  located  in  Asia.   "Asia"   shall  mean  the   following
                  geographical areas:  Australia,  New Zealand and the countries
                  of Asia (including without limitation, Indonesia, Malaysia and
                  the island countries of the Western Pacific Rim; but excluding
                  Russia,  Turkey and the countries of the Middle East from Iran
                  and to the west). No Chi Lin Revenue Royalty shall be owed for
                  any month in which  there are no Asian  Revenues.  The Chi Lin
                  Revenue  Royalty  shall be  effective  immediately  and  shall
                  continue for all Asian  Revenues  received or accrued  through
                  the date of termination of the Revenue Royalty as described in
                  Section 6.2 above.

                           6.2.5 Asian Marketing  Right. Chi Lin, at its option,
                  and upon giving  thirty (30) days written  notice to MicroCor,
                  Wescor and InMedica, shall have the right to terminate the Chi
                  Lin  Revenue   Royalty   and  the  Chi  Lin  Minimum   Royalty
                  permanently in exchange for the exclusive  right to distribute
                  and sell the Products in Asia (the "Asian  Marketing  Right").
                  Chi Lin shall exercise the foregoing right to exchange the Chi
                  Lin Revenue Royalty and the Chi Lin Minimum Royalty rights for
                  the  Asian  Marketing  Right,  if at all,  by the date that is
                  eighteen (18) months  following the Effective  Date. The Asian
                  Marketing   Right,   if  elected,   shall  then  be  effective
                  immediately and shall continue through the date of termination
                  of the Revenue  Royalty as described in Section 6.2 above.  In
                  the event Chi Lin  exchanges  the Chi Lin Revenue  Royalty and
                  the Chi Lin  Minimum  Royalty  rights for the Asian  Marketing
                  Right,  the InMedica Revenue Royalty payable to InMedica shall
                  be based on only non-Asian Revenues.

                  6.3. Minimum Royalty Credit.  Notwithstanding  anything to the
         contrary in this Section 6, the parties  acknowledge and agree that the
         Revenue  Royalty  payments  are intended to be in place of - and not in
         addition  to - the  Minimum  Royalty  payments,  to the extent that the
         Revenue  Royalty   payments   exceed  the  Minimum  Royalty   payments.
         Accordingly,  (i) InMedica  Minimum Royalty  payments made in any given
         calendar  year  shall  be a credit  against  InMedica  Revenue  Royalty
         payments in such calendar year, and InMedica  Revenue Royalty  payments
         shall only be paid to the extent that they exceed the InMedica  Minimum
         Royalty  payments  for such  calendar  year;  and (ii) Chi Lin  Minimum
         Royalty  payments  made in any given  calendar  year  shall be a credit
         against Chi Lin Revenue Royalty payments in such calendar year, and Chi
         Lin Revenue Royalty payments shall only be paid to the extent that they
         exceed the Chi Lin Minimum Royalty payments for such calendar year.

                  6.4 Royalty Buyout Right.  In the event of the occurrence of a
         "MicroCor  Change of Control," the provisions of this Section 6.4 shall
         apply.  "MicroCor  Change of Control" shall mean the acquisition by any
         party or third party of more than eighty percent (80%) of the assets or
         equity securities of MicroCor, or the merger of MicroCor with any party
         or third party where the parties to this Agreement own in the aggregate
         less  than  twenty  percent  (20%)  of  the  equity  securities  of the
         surviving entity.  Upon the occurrence of a MicroCor Change of Control,
         MicroCor,  or its  successors  or  assigns,  shall  have the right (the
         "Buyout  Right"),  notwithstanding  any  contrary  provisions  in  this
         Section 6, to purchase and terminate the Minimum  Royalty,  the Revenue


                                       16


         Royalty and, if applicable, the Asian Marketing Right from InMedica and
         Chi Lin.  MicroCor (or its  successors or assigns)  shall  exercise the
         Buyout  Right,  if at all,  within  twelve  (12) months  following  the
         occurrence of a MicroCor  Change of Control by giving  InMedica and Chi
         Lin thirty (30) days prior  written  notice of its intent to  exercise,
         and by paying to  InMedica  and Chi Lin,  upon the  expiration  of such
         thirty (30) days, the following amounts:

                  (i)      to InMedica, the greater of: (a) $800,000, or
                           (b)      80% of five (5) times the sum of the Minimum
                                    Royalty payments payable for the immediately
                                    preceding   twelve   (12)  months  plus  the
                                    Revenue  Royalty  payments  payable  for the
                                    immediately preceding twelve (12) months;
                  and
                  (ii) to Chi Lin:
                           (A)      if Chi Lin has not  exercised its option for
                                    the Asian Marketing  Right,  the greater of:
                                    (a)  $200,000,  or (b) 20% of five (5) times
                                    the  sum of  the  Minimum  Royalty  payments
                                    payable
                                            for the immediately preceding twelve
                                            (12) months plus the Revenue Royalty
                                            payments payable for the immediately
                                            preceding twelve (12) months, or
                           (B)      if Chi Lin has  exercised its option for the
                                    Asian Marketing  Right,  the greater of: (a)
                                    $200,000  or (b) one  (1)  times  the  gross
                                    revenue Chi Lin has generated in the
                                            immediately  preceding  twelve  (12)
                                            months  through its  exercise of the
                                            Asian Marketing Right.

         In order to verify the relevant  values  described in this Section 6.4,
         the  parties  agree that they shall  make  their  accounting  books and
         records  available to each other or to the parties'  agents,  including
         independent  auditors,  in reasonable form and at reasonable  times and
         places.

         7. Title to  Hematocrit  Technology.  Notwithstanding  anything  to the
contrary  contained  herein,  this  Agreement  shall  not be  construed  to be a
transfer of the Hematocrit Technology to Wescor, and the parties acknowledge and
warrant that subject to Section 1 hereof, the Hematocrit  Technology is and will
be owned  by or  licensed  to  MicroCor  at all  times  during  the term of this
Agreement.  The  term  "Hematocrit  Technology"  shall  include  the  Hematocrit
Technology as presently  constituted  plus any and all additions,  enhancements,
improvements,  and  developments,  whether  developed or discovered by MicroCor,
Wescor,  InMedica,  Chi Lin, or any  employee,  agent,  contractor,  subsidiary,
successor or assignee thereof.

         8.  Disclosure  of  Hematocrit  Technology.  InMedica and Chi Lin shall
disclose  to  MicroCor  and Wescor all aspects of their  existing  research  and


                                       17


findings,  as well as the research and findings in their possession performed by
others,  with respect to the  Hematocrit  Technology.  MicroCor and Wescor shall
keep all such  information  confidential  and  shall  not  disclose  any of such
information to third parties except to the extent allowed  hereunder or required
by law. Nothing herein shall be construed to be, and InMedica and Chi Lin hereby
expressly  disclaim  any,  warranty  or  representation  as to  the  current  or
potential function, success, accuracy, marketability,  profitability or possible
sales of the Hematocrit  Technology or any Products.  Wescor and MicroCor hereby
acknowledge that they have not relied on any such warranty or representation and
further  acknowledge  that  there  is a  significant  amount  of risk  that  the
Hematocrit Technology and the Products will not be developable, will not receive
FDA Clearance, or cannot be manufactured and marketed profitably, and that there
are other significant risk factors involving research, regulatory,  business and
economic  variables  over which  InMedica and Chi Lin have no control that could
negatively impact the success of the Hematocrit Technology and the Products.

         9.  Condition  Precedent.  Notwithstanding  anything  to  the  contrary
contained  herein,  the rights  granted and  obligations  assumed  hereunder are
conditioned   upon  the  approval  by  the   shareholders  of  InMedica  of  the
transactions  described herein.  InMedica  represents and warrants that it shall
act with all reasonable speed and diligence to obtain such approval  pursuant to
all applicable  corporate and securities  laws and regulations as advised by its
legal  counsel.  Chi Lin,  Larry E. Clark,  Ralph  Henson and Richard  Bruggeman
covenant and agree that they shall each vote their respective shares of InMedica
stock in favor of approving the transactions  described  herein.  InMedica shall
deliver to the other parties to this  Agreement a written  notice of the results
of seeking  shareholder  approval  within ten (10) days  following  the relevant
shareholder  action. If InMedica delivers a notice stating that its shareholders
have not approved the transactions,  or if no written notice  (regardless of its
contents) has been  delivered by the date that is forty five (45) days following
the date this  Agreement  is  executed  by all  parties,  this  Agreement  shall
automatically  terminate.  Before  the  end  of  such  45-day  period  (and  any
successive  45-day extension  period),  InMedica may deliver a written notice to
the  other  parties  extending  such  deadline  by forty  five  (45) days if the
Securities and Exchange  Commission has not acted on InMedica's request that the
appropriate  information statement and/or proxy statement be approved for use in
connection with seeking the shareholder  approval described in this Section.  In
the event of such automatic  termination,  the parties shall take all reasonable
actions to return any items,  repay any funds or  otherwise  put each other back
into the same situation they were in prior to the execution of this Agreement.

         10. Audit of Financial Records. For purposes of confirming  performance
of obligations under this Agreement,  InMedica and Chi Lin shall have the right,
at their expense,  at all reasonable times and from time to time, to review,  or
engage an independent  auditor to review, the accounting and operational records
of MicroCor and Wescor.  MicroCor  and Wescor  shall keep and maintain  accurate
records of their  accounting data that shall  reasonably and accurately  reflect
their  operations  and shall  maintain such records for at least three (3) years
following  the close of each  relevant  accounting  period.  MicroCor and Wescor
shall  make all such  information  available  to  InMedica  or Chi Lin upon such
party's  written  request  either by providing  access thereto at the offices of
MicroCor or Wescor,  or by copying all such information and delivering it to the
requesting  party.  Either InMedica or Chi Lin shall have the right to terminate
this  Agreement if either  MicroCor or Wescor  fails to perform its  obligations
under this Section, or provides inaccurate or false records under this Section.

         11. Miscellaneous.

                  11.1. Expenses. Except as otherwise expressly provided in this
         Agreement,  each  party to this  Agreement  shall  bear its  respective
         expenses  incurred in connection with the preparation,  execution,  and
         performance of this Agreement and the transactions contemplated hereby,
         including  all fees and expenses of agents,  representatives,  counsel,

                  11.3.   Jurisdiction;   Service  of  Process.  Any  action  or
         proceeding  seeking to enforce any  provision of, or based on any right
         arising out of, this  Agreement  shall be brought  only in the state or
         federal courts  located in the County of Salt Lake,  State of Utah, and
         each of the parties hereby consents and agrees to the sole jurisdiction
         of such courts (and of the  appropriate  appellate  courts) in any such
         action or  proceeding  and waives any  objection to venue laid therein.
         Process  in any  action  or  proceeding  referred  to in the  preceding
         sentence may be served on any party anywhere in the world.

                  11.4.  Further  Assurances.  The parties  agree (a) to furnish
         upon request to each other such further information, (b) to execute and
         deliver to each other  such other  documents,  and (c) to do such other
         acts and things,  all as the other party may reasonably request for the
         purpose of carrying out the intent of this  Agreement and the documents
         and  transactions  referred to in this Agreement.  Each party agrees to
         use its best efforts in good faith to fulfill its obligations hereunder
         in a timely and efficient manner.

                  11.5.  Waiver.  The rights and remedies of the parties to this
         Agreement are cumulative and not  alternative.  Neither the failure nor
         any delay by any party in  exercising  any right,  power,  or privilege
         under this  Agreement or the  documents  referred to in this  Agreement
         will operate as a waiver of such right,  power,  or  privilege,  and no
         single or partial exercise of any such right,  power, or privilege will
         preclude  any  other or  further  exercise  of such  right,  power,  or
         privilege or the exercise of any other right,  power, or privilege.  To
         the maximum extent  permitted by applicable  law, (a) no claim or right
         arising  out of this  Agreement  or the  documents  referred to in this
         Agreement  can be  discharged  by one party,  in whole or in part, by a
         waiver or  renunciation  of the claim or right unless in writing signed
         by the other party;  (b) no waiver that may be given by a party will be
         applicable  except in the specific  instance for which it is given; and
         (c) no notice  to or demand on one party  will be deemed to be a waiver
         of any  obligation  of such  party or of the right of the party  giving
         such notice or demand to take further  action  without notice or demand
         as  provided in this  Agreement  or the  documents  referred to in this
         Agreement.

                  11.6.   Entire   Agreement;   Modification.   This   Agreement
         supersedes all prior agreements between the parties with respect to its
         subject matter and constitutes (along with the documents referred to in
         this Agreement) a complete and exclusive  statement of the terms of the
         agreement between the parties with respect to its subject matter.  This
         Agreement may not be amended except by a written agreement  executed by
         the party to be charged with the amendment.

                  11.7.  Assignment;  Successors;  No Third-Party Rights. Except
         for  MicroCor's  right to  sublicense,  assign or transfer  the Chi Lin
         License  described  in Section  1.2,  and  except for any other  rights
         described in this  Agreement that by their express terms are assignable
         or  transferable,  no party  hereto may assign any of its rights  under
         this Agreement  without the prior written consent of the other parties.
         Subject to the preceding  sentence,  this Agreement  shall apply to, be
         binding  in  all  respects  upon,  and  inure  to  the  benefit  of the
         successors and permitted  assigns of the parties.  Nothing expressed or


                                       20


         referred to in this Agreement  shall be construed to give any person or
         entity other than the parties to this  Agreement any legal or equitable
         right,  remedy, or claim under or with respect to this Agreement or any
         provision of this  Agreement.  This Agreement and all of its provisions
         and conditions are for the sole and exclusive benefit of the parties to
         this Agreement and their successors and assigns.

                  11.8. Severability. If any provision of this Agreement is held
         invalid or  unenforceable by any court of competent  jurisdiction,  the
         other  provisions  of this  Agreement  shall  remain in full  force and
         effect.  Any provision of this Agreement held invalid or  unenforceable
         only in part or degree  shall  remain in full  force and  effect to the
         extent not held invalid or unenforceable.

                  11.9. Section Headings; Construction. The headings of Sections
         in this Agreement are provided for convenience only and will not affect
         its  construction  or  interpretation.  All  references to "Section" or
         "Sections"  refer to the  corresponding  Section  or  Sections  of this
         Agreement.  All words used in this Agreement will be construed to be of
         such gender or number as the  circumstances  require.  Unless otherwise
         expressly  provided,  the word "including" does not limit the preceding
         words or terms.

                  11.10.  Time of  Essence.  With  regard  to all dates and time
         periods  set forth or  referred  to in this  Agreement,  time is of the
         essence.

                  11.11.  Governing Law. This Agreement shall be governed by the
         laws  of the  State  of  Utah  without  regard  to  conflicts  of  laws
         principles.

                  11.12. Counterparts.  This Agreement may be executed in one or
         more counterparts,  each of which will be deemed to be an original copy
         of this Agreement and all of which, when taken together, will be deemed
         to  constitute  one and the same  agreement.  Execution and delivery of
         this  Agreement  by facsimile  machine  shall be deemed as effective as
