Introduction

This Management's  Discussion and Analysis of Financial Condition and Results of
Operations contains forward-looking  statements. The actual results might differ
materially from those projected in the  forward-looking  statements.  Additional
information  concerning  factors that could cause actual  results to  materially
differ from those in the forward-looking statements is described below under the
heading  "Factors  That May  Affect  Future  Results"  and is  contained  in the
Company's other SEC filings,  including its Registration  Statement on Form S-1,
copies of which are available upon request from the Company.

The  following  discussion  should  be read in  conjunction  with the  unaudited

report.  Unless the context indicates  otherwise,  all references to the Company
include   Cardiovascular   Diagnostics,   Inc.  and  its   subsidiaries,   Coeur

disposable  test cards which are inserted into the analyzer to perform a variety
of hemostasis tests. Coeur currently manufactures and sells a line of disposable
syringes  used in  angiography  injectors,  as  well  as a line of  angiographic
procedure kit manifolds (collectively, "Imaging Products").

Results of Operations

Three Months Ended September 30, 1996 vs. September 30, 1995

Net sales for the three  months ended  September  30, 1996 were  $1,572,000,  an
increase of 12% or  $169,000,  as  compared to the same period in 1995.  The net
increase reflects  increased TAS sales of $306,000 1995 to 1996, offset by lower
Imaging  Product sales of  $1,143,000 in 1996 as compared to $1,280,000  for the
same period in 1995. The lower Imaging Product sales were a result of production
delays  experienced in the third quarter due to a raw material supplier problems
which created a sales backlog. The Company believes that this situation has been
resolved and the backlog was filled in October.

Cost of  goods  sold  increased  $127,000  or 11%  from  September  30,  1995 to
September 30, 1996, as a direct result of increased sales of TAS products. Gross
profit  increased  16% for the  three-month  period ended  September 30, 1996 as
compared to the same period in 1995.

Total operating expenses increased $628,000 for the three months ended September
30, 1996 as compared to the same period in 1995. This increase was primarily due
to increased  staffing,  as headcount  increased to 85 employees as of September
30, 1996 from 61 employees as of September 30, 1995.

Administration and finance expenses increased $243,000, or 53%, due to increased
staffing,  as well as  additional  expenses,  such as those  related  to being a
public company.

Sales and marketing  expenses for the three months ended September 30, 1996 were
$173,000 greater than the same period in 1995, reflecting increased staffing and
travel  expenses,  as well as  increased  advertising  expenses  to  expand  the
marketing efforts related to TAS products.


                                        7

<PAGE>

Research and  development  expenses were  $212,000  greater for the three months
ended September 30, 1996 than for the same period in 1995. This increase was due
to  additional  engineering  support for  continued  product  and  manufacturing
development.

Interest income  increased  $130,000 for the three-month  period ended September
30,  1996  from the  three-month  period  ended  September  30,  1995 due to the
investment of the funds  received from the Company's  initial  public  offering,
which was  consummated  in December  1995.  Grant and royalty  income  decreased
$92,000  from the  three-month  period in 1996 as compared to the same period in
1995. During the three-month  period ended September 30, 1996 there was no grant
or royalty income.

Nine Months Ended September 30, 1996 vs. September 30, 1995

Net sales for the nine  months  ended  September  30, 1996 were  $4,796,000,  an
increase  of  25%  or  $974,000,  as  compared  to  the  same  period  in  1995.
Approximately  $929,000 of the increase from 1995 to 1996 was generated from TAS
sales,  which did not  commence on a commercial  basis until May 1995.  Sales of
Imaging Products for the nine months ended September 30, 1996 were $3,558,000 as
compared to $3,513,000 for the nine months ended September 30, 1995.

Cost of  goods  sold  increased  $876,000  or 31%  from  September  30,  1995 to
September  30, 1996,  primarily as a result of increased  sales of TAS products.
Gross  profit  increased  10% for the nine months  ended  September  30, 1996 as
compared to the same period in 1995 however,  the gross profit margin  decreased
3%.

Total  operating  expenses  increased  $1,835,000  for  the  nine  months  ended
September  30, 1996 as compared to the same period in 1995.  This  increase  was
primarily due to increased  staffing,  expansion of the  facilities,  additional
sales  and  marketing  expenses,   and  continued  validation  of  manufacturing
processes.

Administration and finance expenses increased $785,000 for the nine months ended
September  30, 1996 as compared  to the same period in 1995,  due to  additional
staffing,  increased  rent and  associated  expenses  incurred with the facility
expansion and associated expenses for a public company.

Sales and marketing  expenses for the nine months ended  September 30, 1996 were
$677,000  greater  than  the  same  period  in 1995.  This  increase  was due to
additional  staffing,  associated travel expenses and advertising as the Company
expanded marketing efforts related to TAS products.



Research and development  expenses for the nine-month period ended September 30,
1996 increasesd $373,000 due to additional  staffing,  increased efforts for new
test card  development,  and 510(k)  submissions  and associated  field/clinical
trials.

Interest income increased  $443,000 for the nine months ended September 30, 1996
from the nine months  ended  September  30, 1995 due to the  investments  of the
funds received from the Company's initial public offering, which was consummated
in December 1995. Grant and royalty income decreased $322,000 in the nine months
ended  September  30,  1996,  as  compared  to the same  period in  1995
primarily  as a  result  of the Company  changing its  focus from  research
and development to commercialization.

Liquidity and Capital Resources

In December 1995, the Company completed its initial public offering,  generating
net  proceeds of  approximately  $16,700,000.  In January  1996,  an  additional
100,000  shares were  purchased by the  underwriters  to cover  over-allotments,
which resulted in the Company receiving additional net proceeds of approximately
$1,000,000.

From  December  31,  1995 to  September  30,  1996,  cash and  cash  equivalents
decreased  $14,336,000.  A portion  of this  decrease  was due to  purchases  of
Treasury Bills and Treasury Notes of  $10,688,000  during the nine-month  period
ended September 30, 1996. These  investments have maturity dates greater than 90
days  and  accordingly  have  been  classified  as  investments.   In  addition,
utilization of cash for  operations was  $5,181,000,  capital  expenditures  for
property and equipment  were  $1,145,000 and repayment of debt  obligations  was
$726,000.

Accounts  receivable  increased $425,000 from December 31, 1995 to September 30,
1996 due to the increase in TAS sales during 1996.

The Company  expects to incur  additional  operating  losses  during  1996.  The
Company's working capital  requirements  will depend on many factors,  primarily
the  amount of time for  hospitals  to  complete  evaluations  of TAS and decide
whether or not to purchase  TAS  analyzers  and test  cards.  In  addition,  the
Company  expects to incur costs  associated  with  clinical  trials for new test
cards.  The Company may acquire other products,  technologies or businesses that
complement  the Company's  existing and planned  products,  although the Company
currently has no understanding, commitment or agreement with respect to any such
acquisitions.

Management  believes that its existing capital resources and the cash flows from
operations will be adequate to satisfy its planned capital  requirements through
at least 1997.

Factors That May Affect Future Results

A number of  uncertainties  exist that may affect the Company's future operating
results and stock price,  including  managed  care,  FDA  regulations  and other
regulatory  guidelines  affecting  the  Company.  The market price of the Common
Stock could be subject to significant  fluctuations in response to variations in
the Company's quarterly operating results, as well as other factors which may be
unrelated  to the  Company's  performance.  The stock market in recent years has
experienced extreme price and volume fluctuations that often have been unrelated
or disproportionate to the operating performance of or announcements  concerning
public companies.  Such broad fluctuations may adversely affect the market price
of the Company's  Common Stock.  Securities of issuers having  relative  limited
capitalization  or securities  recently issued in an initial public offering are
particularly susceptible to volatility based on short-term trading strategies of
certain investors.

                  Alliance Cards in such accounts which Dade determines are
                  targets for hemostasis point of care systems. CVDI and Dade
                  shall comply with the Act and other applicable, legal, health
                  and safety requirements, laws and regulations in all of their
                  marketing and sales activities. Neither CVDI nor Dade shall
                  promote the Products for any uses not approved for Products by
                  applicable regulatory agencies.
         2.5      Terms and Conditions.  All orders for Products shall be
                  initiated by written purchase orders.  No order shall be
                  binding unless consistent with this Agreement.
                  Acceptance by CVDI of Dade's purchase order is expressly
                  limited to and conditioned upon, and only upon, Dade's
                  acceptance of the terms and conditions set forth in this
                  Agreement, which may not be changed or waived except in
                  a writing signed by the parties.  Dade's purchase orders
                  submitted to CVDI shall be governed by the terms of this
                  Agreement and CVDI's published Standard Terms and
                  Conditions of Sale as in effect at the time of such
                  purchase; provided, however, that in the event of a
                  conflict between the terms of this Agreement and CVDI's
                  Standard Terms and Conditions of Sale, this Agreement
                  shall control and any additional, inconsistent or
                  different terms and conditions contained in any purchase

                  order, acknowledgment, confirmation, acceptance, invoice, or
                  other documents supplied by Dade or CVDI are hereby expressly
                  rejected. A copy of CVDI's Standard Terms and Conditions of
                  Sale is attached hereto as Schedule 2.5. CVDI shall not
                  arbitrarily change its Standard Terms and Conditions. CVDI
                  shall limit its changes to correcting typographical errors,
                  conforming the terms and conditions to applicable law, and
                  changes to make the Standard Terms and Conditions consistent
                  with terms and conditions offered in the marketplace for
                  comparable products. CVDI shall advise Dade in writing at
                  least thirty (30) days in advance of any proposed changes
                  (other than minor non-material corrections) to the Standard
                  Terms and Conditions. The parties shall discuss and attempt to
                  reach agreement concerning the proposed changes which Dade
                  indicates affect Dade or its ability to market or sell the
                  Products. Dade and CVDI agree that such orders and documents
                  may include provisions which identify Products, quantities of
                  Products, shipping dates, delivery information and prices and
                  billing information in a manner not inconsistent with this
                  Agreement and such provisions shall be binding on the parties.
         2.6      Rejection.  Dade and its distributors shall notify CVDI
                  of obvious damage relating to the manufacturing or
                  packaging of the Products (other than damage solely
                  associated with the shipping of the Products) within
                  forty-five (45) days of their respective receipt of the
                  Products.  Any such Product not rejected for obvious
                  damage within forty-five (45) days after receipt by Dade
                  or its distributors (the "Rejection Period") shall be
                  deemed accepted.  A rejection by Dade shall mean that
                  CVDI has received within the Rejection Period written
                  notice of such rejection stating with particularity the

                                       8







<PAGE>



                  reason therefor. CVDI shall as promptly as possible replace
                  any rejected Products at no cost to Dade or its distributors.
                  After the Rejection Period, Dade may not return any such
                  obviously damaged Products for any reason without CVDI's prior
                  written consent.
         2.7      Expansion of Territory.  CVDI will promptly advise Dade
                  in writing of opportunities for extension of Dade's
                  distribution rights into any country in which CVDI
                  desires to expand or any country where existing rights
                  lapse or are subject to competitive bid where Dade has a
                  distribution network in place.  CVDI agrees not to enter
                  into any contract for distribution rights in such other
                  country until the earlier of the receipt of a proposal
                  from Dade regarding such country or the expiration of the
                  ninety (90) day period following Dade's receipt of
                  written notification pursuant to this sub-section.  In-
                  considering the award of any expansion territory, the
                  parties hereto agree to consider the relationship of CVDI
                  and Dade and Dade's performance hereunder as a criteria
                  in making any such award.  Nothing in this subsection
                  shall limit the rights of CVDI to solicit, review or
                  negotiate with any party at any time with respect to
                  areas outside the Territory as the same may exist from
                  time to time.
3.       Marketing and Support Activities.
         3.1      Marketing Meetings: Reports.  The parties shall meet at
                  least semi-annually to discuss market plans, product
                  improvement suggestions and other information concerning
                  the marketing and development of the Products.  Dade
                  shall provide information available to it about the
                  Products and their ability to compete with other
                  diagnostic products for related uses and to meet customer
                  needs.  Dade shall provide CVDI general information

                                       9







<PAGE>



                  regarding sales of the Products such as broad pricing trends
                  by geographic region as well as sales information indicating
                  sales by country or geographic region, where available to
                  Dade.
         3.2      Promotional Material.  CVDI will furnish Dade with copies
                  of promotional literature and advertisements it prepares
                  for the Product.  Dade shall not copy or utilize any
                  promotional material prepared by it without obtaining the
                  prior written approval thereof from CVDI.  CVDI's
                  approval shall not be unreasonably withheld or delayed.
                  Dade shall submit by courier camera ready copy for the
                  labels and package inserts to CVDI for approval.  CVDI
                  shall respond within fourteen (14) days of receipt.  If
                  no written objection is received from CVDI within
                  fourteen (14) days after the courier package is received
                  by CVDI, Dade will contact CVDI to obtain CVDI's approval
                  for the copy as submitted, or as modified in accordance
                  with CVDI's instructions.  CVDI and Dade shall comply
                  with all requirements of the Act, local laws, regulations
                  and other laws in their advertising and other promotional
                  activities.
         3.3      Packaging, Labeling.  CVDI shall manufacture, label and
                  package the Products in final form for distribution by
                  Dade.  Dade shall provide camera ready copy for the
                  labels containing Dade trade dress.  In addition to all
                  applicable legal requirements, the labels shall comply
                  with the requirements set forth in Section 3.4 below,
                  shall display "CVDI" and shall identify CVDI as the
                  manufacturer of the Products.  Dade shall not repackage
                  or label any Products and shall not alter any Products or
                  any package or label used in connection with any Products
                  except as specifically authorized by CVDI.  In the event
                  that CVDI shall authorize or require repackaging or
                  re-labeling, Dade shall comply in all respects with the
                  instructions of CVDI, at the expense of CVDI.

         3.4.     Trademarks and Trade Names.  CVDI hereby grants Dade, the
                  nontransferable right to use in the Territory the
                  trademarks and tradenames listed on Schedule 3.4, and any
                  other trademarks owned by CVDI which it may designate in
                  writing for use by Dade (the "Trademarks"), in connection
                  with the marketing and sale of the Products for the
                  duration of the Agreement.  Dade's distributors and
                  Affiliates shall be entitled to the use of such
                  Trademarks, subject to the terms and conditions of this
                  Agreement, so long as such use is authorized only in
                  connection with distribution of Products hereunder and
                  subject to terms and conditions substantially similar to
                  those contained in this Agreement.  The Product shall be
                  marketed and sold only under the Trademarks, the name
                  "CVDI" as required under Section 3.3 and such other marks
                  as Dade may use for its other hemostasis products.  Dade
                  acknowledges that it has and will obtain no proprietary
                  interest in the Trademarks and agrees not to use the same
                  as part of its corporate or business name.  Dade's, its
                  distributors' and Affiliates', right to the use of any
                  Trademark or other property of CVDI shall terminate
                  immediately upon termination of this Agreement; provided,
                  however, such right shall be extended for the period of
                  time specified in Section 11.5, at the end of which all
                  such rights shall terminate.  Dade shall use the
                  Trademarks only in the manner prescribed by CVDI.  Dade
                  hereby grants CVDI the nontransferable right to use in
                  the Territory the trademarks and tradenames listed on
                  Schedule 3.4, and any other trademarks owned by Dade
                  which it may designate in writing for use by CVDI (the
                  "Dade Trademarks"), in connection with the marketing and
                  sale of the Products.  During the period of exclusivity,
                  the Products shall be marketed and sold only under the
                  Trademarks, the Dade Trademarks, and such other marks as
                  CVDI may use for its other hemostasis products.  During
                  any period of non-exclusivity, the Products sold to Dade

                                       11







<PAGE>



                  shall be sold only under the Trademarks and the Dade
                  Trademarks and such other marks as CVDI may use for its other
                  hemostasis products. CVDI acknowledges that it has and will
                  obtain no proprietary interest in the Dade Trademarks and
                  agrees not to use the same as part of its corporate or
                  business name. CVDI's right to the use of any Dade Trademark
                  or other property of Dade shall terminate immediately upon
                  termination of this Agreement and CVDI shall, upon conversion
                  of this Agreement to a non-exclusive distributorship, cease
                  soliciting orders for Cards bearing the Dade Trademark as more
                  fully set forth in Section 11.2. CVDI shall use the Dade
                  Trademarks only in the manner prescribed by Dade. The Products
                  are offered for sale and sold by Dade and CVDI subject in
                  every case to the condition that such sale does not convey any
                  licenses, express or implied, to manufacture, duplicate or
                  otherwise copy or reproduce any Product. In the event of
                  termination of this Agreement, neither party shall manufacture
                  or have manufactured any devices, cards, components or
                  assemblies utilizing any information belonging solely to the
                  other party.
         3.5      Marketing Assistance/Training.  CVDI agrees to provide
                  technical training, and technical assistance to Dade
                  personnel at periodic intervals, with the frequency and
                  content to be determined by mutual agreement.  The
                  training and technical assistance provided to Dade shall
                  be no less than that provided to CVDI employees and sales
                  force, and shall be updated from time to time with at
                  least the frequency such updates are provided to CVDI
                  employees and sales force.  Each party to this Agreement
                  shall be responsible for its own expenses in connection
                  with any such training and assistance.
         3.6      Support. CVDI agrees, upon request from Dade, to use
                  reasonable efforts to sell and promote Specialty Products to
                  identified customers of Dade where such request is
                  commercially feasible in the sole discretion of CVDI.

                  From time to time, CVDI may request Dade's assistance in
                  offering for sale CVDI's Specialty Products to individual
                  operating room customers of CVDI and, to customers of CVDI
                  distributors of Specialty Products in the Territory. CVDI
                  presently intends to have no more than two (2) distributors,
                  excluding Dade, for Specialty Products in the Territory. In
                  the event that CVDI seeks an additional distributor of
                  Specialty Products, CVDI will promptly advise Dade in writing
                  of the opportunity for Dade to distribute Specialty Products.
                  CVDI agrees not to enter into any contract for such
                  distribution rights until the earlier of the receipt of a
                  proposal from Dade regarding such distributorship or the
                  expiration of the thirty (30) day period following Dade's
                  receipt of written notification pursuant to this subsection.
                  In considering the award of such distribution, CVDI agrees to
                  consider Dade's performance hereunder as a criteria in making
                  such award. In Dade's sole discretion and upon terms mutually
                  agreeable to Dade and to CVDI, Dade will, upon request of
                  CVDI, offer for sale CVDI's Specialty Products to such
                  operating room customers. Dade shall receive a [ ] ([ ]%)
                  percent commission on any such sale, payable within thirty
                  (30) days after CVDI or such partner/distributor receives
                  payment. In Dade's sole discretion, and upon terms mutually
                  agreeable to Dade and CVDI, Dade will, upon request of CVDI,
                  offer for sale CVDI's Specialty Products to Integrated Health
                  Networks. The commission Dade shall receive shall be on terms
                  to be mutually agreed upon by the parties. Unless otherwise
                  agreed by the parties, Dade's commission shall be paid within
                  thirty (30) days after CVDI receives payment. CVDI will advise
                  Dade on a monthly basis of the number of Specialty Products
                  sold by CVDI in accordance with this Section.

         3.7      Service.  Except as otherwise provided in this Section,
                  CVDI agrees to provide service and maintenance for
                  Instruments sold by Dade for its standard fees, as they
                  exist from time to time, and in accordance with its then
                  applicable standard service agreement.  CVDI shall offer
                  service contracts for Instruments to customers to provide
                  maintenance and services in accordance with its standard
                  contract.  CVDI shall provide Dade with its service
                  contract price list and, at its option, Dade shall be
                  entitled to sell such contracts on behalf of CVDI.  Dade
                  shall bill for the service contracts which it sells and
                  payment by Dade to CVDI shall be within thirty (30) days
                  after Dade receives payment for such service/maintenance
                  contract.  Service and maintenance shall be provided by
                  CVDI or an independent third party service company.  To
                  the extent that CVDI intends to contract with a third
                  party for service and maintenance of the Products, CVDI
                  will promptly advise Dade in writing of the opportunity
                  for Dade to perform such service and maintenance.  CVDI
                  agrees not to enter into any contract with a third party
                  for service and maintenance of the Products until the
                  earlier of the receipt of a proposal from Dade regarding
                  such service/maintenance or the expiration of the thirty
                  (30) day period following Dade's receipt of a written
                  notification pursuant to this subsection.  In considering
                  the award of such service/maintenance opportunity, CVDI
                  agrees to consider Dade's performance hereunder as a
                  criteria in making such award.
         3.8      Product Warranty. Neither party nor its subdistributors shall
                  make any representation or warranty about the Products,
                  whether in writing or orally, except as is contained in
                  written materials delivered to Dade by CVDI expressly for use
                  in promoting the sale of the Product or as may otherwise be
                  agreed to by CVDI in writing.

                  and enhancements of the Products and other products,
                  including increasing the dating of the CVDI Cards,
                  Alliance Cards and Dade Alliance Cards consistent with
                  the provisions of Exhibit 6.4.  CVDI shall consult with
                  Dade from time to time about improvements which may be
                  desired by Dade and end users without obligation to CVDI.
                  Dade may, in its sole discretion, provide product
                  suggestions, information about integration with its
                  hemostasis instruments, results of focus sessions and
                  other expectations of end users, and access to technology
                  available to it which may be useful to CVDI.
         4.2      Certain Payments by Dade.  CVDI agrees to perform certain
                  research and development projects during the term of this
                  Agreement, as more fully set forth on Schedule 4.2
                  hereof.  CVDI will use its best efforts to develop a 25
                  card sample pack.  CVDI will use its best efforts to
                  extend the minimum card dating of PT cards in accordance
                  with the specifications set forth on Exhibit 6.4.  There
                  shall be no charge to Dade for such research and
                  development projects.  CVDI further agrees to use its
                  best efforts to perform three research and development
                  projects, if funded in part by Dade, during the term of
                  this Agreement, as more fully set forth on Schedule 4.2
                  hereof.  These three projects are: the calibration of
                  CVDI Cards to Dade PT and aPTT reagents, adding Dade's
                  [       ] (either reagent or raw material) and new PTT
                  (either reagent or raw material) to CVDI Cards and the
                  development of an additional Specialty Card.  Timelines
                  and milestones for the first two (2) projects are set
                  forth on Schedule 4.2.
                  On January 6, 1997, Dade shall pay CVDI the sum of
                  $[            ] for use by CVDI in the Alliance Cards
                  project.  Upon compliance in all material respects with

                  the Specialty Cards resulting from the Specialty Cards project
                  in the United States.
                  In no event shall Dade's payments to CVDI pursuant to
                  this Section 4.2 exceed US$[ ] without Dade's prior
                  written consent. Notwithstanding any provision in this
                  Agreement to the contrary, upon termination of this
                  Agreement or upon conversion by CVDI of this Agreement
                  to a non-exclusive distributorship by Dade, Dade's

                  right, title, and interest in and to the know-how and

                  ownership of the components of the Dade Alliance Cards
                  and the Specialty Card at the time such project is

                  obtain and maintain regulatory approvals and requirements for
                  it to sell the Products and New Products in the Territory.
                  CVDI agrees to cooperate with Dade in any regulatory process
                  to permit Dade to participate in such process where feasible.
                  CVDI shall have sole discretion as to the commercial
                  reasonableness of any acts required on its part to maintain
                  any regulatory approval or requirement.

                  (b) CVDI shall promptly provide to Dade copies of all required
                      Product notifications and registrations to regulatory
                      agencies (including device listing reports) including
                      copies of all letters received from the FDA.

         5.2      Reporting Obligations.  Dade shall maintain, or cause to
                  be maintained, all complaint files and other records
                  required to be maintained by the FDA and other regulatory
                  agencies with respect to Products purchased by Dade and
                  its Affiliates from CVDI.  CVDI shall promptly provide to
                  Dade copies of all complaints received with respect to
                  the Products sold to Dade as well as responses sent, if
                  any.  Dade shall promptly provide CVDI with copies of any
                  complaints relating to the Products received by Dade.
                  Except to the extent Dade is otherwise required by law,
                  CVDI shall submit to the FDA all reports of complaints,
                  malfunctions, failures or deterioration in the
                  characteristics or performance or instructions for use or
                  inadequacy in labeling which may have led or lead to
                  death or serious injury and all other information about
                  the Products required to be submitted to any regulatory
                  agency, including the reports required under 21 CFR Parts
                  803 and 804 applicable to the Products.
         5.3      Manufacturing. CVDI shall use its best efforts to comply with
                  all applicable GMP requirements, including all national
                  technical and quality standards applicable to the Products
                  which are incorporated into GMP. From time-to-time, with
                  reasonable prior notice to CVDI, Dade

                                       18

                  may inspect CVDI facilities and upon reasonable request,
                  review CVDI's methods used to audit its subcontractors for GMP
                  compliance. CVDI shall have sole discretion as to the
                  commercial reasonableness of any acts required on its part
                  with respect to GMP compliance, provided, however, CVDI shall
                  notify Dade of any citations from discussions with a
                  regulatory body where such discussions and citations relate to
                  a material aspect of GMP compliance.
         5.4      Samples.  CVDI shall retain samples of each lot of the
                  Products for time periods which are in accordance with
                  GMP.
         5.5      Product Recalls and Field Corrective Actions.  In the
                  event (i) any government authority issues a directive or
                  order that a Product be recalled, (ii) a court of
                  competent jurisdiction orders such a recall or (iii) Dade
                  and CVDI determine that a Product should be recalled or
                  that a Field Corrective Action should occur, the parties
                  shall take all appropriate corrective actions.  If CVDI
                  and Dade cannot agree as to whether or not a Product
                  should be recalled or that a Field Corrective Action
                  should occur, the parties will select a mutually agreed
                  upon third party to assist them in the decision process.
                  The parties shall share equally all costs and expenses
                  associated with such third party involvement.  If, after
                  consultation with such third party, CVDI and Dade cannot
                  agree as to whether or not a Product should be recalled
                  or that a Field Corrective Action should occur, and Dade
                  obtains an opinion of counsel that the Product should be
                  recalled or some Field Corrective Action should occur,
                  Dade shall so notify CVDI and shall be entitled to
                  initiate the appropriate corrective action.  Dade or its
                  Affiliates will provide notice to customers of the recall
                  of the Product.  Upon determination of the party
                  responsible for the recall or Field Corrective Action,
                  such party shall be responsible for the cost of notifying

                                       19

                  end users and for determining the corrective actions to be
                  taken and the costs associated with such actions. CVDI and
                  Dade shall fully cooperate with one another and provide all
                  reasonable assistance in conducting any recall or Field
                  Corrective Action under this Paragraph. Dade shall maintain
                  records of all sales of the Products sufficient to carry out a
                  recall with respect to Products purchased under the Agreement.

                           Cards unless any such order contains terms or
                           conditions inconsistent with orders placed with
                           similarly situated customers) from Non-Dade Accounts.

                           to orders of CVDI Cards, Alliance Cards, Dade
                           Alliance Cards, and Specialty Cards to Non-Dade

                           acceptance, and Dade will accept orders of Cards
                           unless any such order contains terms or conditions
                           inconsistent with orders placed with similarly
                           situated customers), during the period of
                           exclusivity, Dade shall be entitled to retain [ ]

                           net sales price of such cards by Dade and the net
                           cost to Dade applicable at the time of such sale. For
                           purposes of this Agreement, the term "net sales
                           price" shall mean Dade's invoiced price to the

                           incurred by Dade. Dade shall pay CVDI the [ ]% within
                           thirty (30) days of payment by the customer to Dade.
                           Notwithstanding anything to the contrary in this
                           Section, Dade shall retain 100% of the profits from
                           the sale of Products in the Territory by Dade.
                  (b)      CVDI shall manufacture, test, package, label and

                           relating to the Products for the time periods
                           required by applicable laws and regulations.  CVDI
                           shall make such data available to the FDA upon
                           request of the FDA, such request being made either
                           directly to Dade or to CVDI, or otherwise as
                           required by applicable law.
                  (e)      Dade Reagents.  During the term of this Agreement,
                           Dade shall sell its reagents and products and its

                           forth on Schedule 5.6(e).  Prices for such reagents
                           may be adjusted annually in an amount not to exceed
                           the increase in the Producer Price Index for the
                           immediately prior calendar year, such adjustment to
                           begin not earlier than January 1, 1998.  Prices for
                           such Sysmex equipment may be adjusted annually in
                           amounts not to exceed the Producer Price Index, but
                           in no event, shall such price be less than the
                           actual landed price to Dade.  Dade shall sell
                           certain raw materials to CVDI in accordance with
                           terms, conditions, and pricing to be negotiated

                           Dade shall provide monthly, by the fifteenth day of
                           each month, its estimated forecast of its and its

                           the six (6) months following the end of the month
                           in which such forecast is submitted (each a

                           and updates thereof for any period will constitute a
                           firm obligation of Dade to purchase the quantities of
                           Cards indicated only for the first three months of
                           such Forecast.
                  (b)      Purchase orders.  In January, February and March,
                           1997, Dade will order CVDI, Alliance, Dade Alliance
                           Cards, and/or Specialty Cards ("Cards") on a level

                           obligation shall be reduced on a card for card
                           basis by the amount of Specialty Products sold by
                           Dade, pursuant to the provisions of Section 3.6
                           above, beginning ninety (90) days from the date of

                  (c)      Delivery.  CVDI shall use its best efforts to
                           supply the Products ordered by Dade and by its

                           specified by Dade provided; however, CVDI shall not
                           be obligated to deliver Cards to the extent that
                           orders for such Cards exceed 125% of the quantities
                           stated in the portion of any forecast which
                           contains the firm obligation of Dade to purchase
                           Cards.  CVDI shipments of Products shall be

                           paid by Dade. (Packing for refrigerated distribution
                           is not a special packing expense.) Dade shall bear
                           any and all applicable taxes, duties and similar
                           charges that may be assessed against the Products

                           reasonable requests.
         5.8      Packaging.  All Alliance Card, Dade Alliance Card and
                  Specialty Card labels and labeling produced by CVDI,
                  including in terms of packaging layout, design and color,
                  shall be consistent with artwork supplied or approved by
                  Dade.  CVDI shall provide all necessary labels and
                  package inserts for all CVDI Cards, Specialty Cards,
                  Alliance Cards, and Dade Alliance Cards as well as for
                  the shipping container, which labels and package inserts
                  shall comply with applicable FDA requirements. Dade shall
                  not use any other labels or package inserts for any of
                  such cards.
         5.9      Taxes; Duties.  The actual amount of sales, use, excise,
                  value-added and similar taxes levied upon or applicable
                  to the transfer of Product to Dade or its Affiliates are
                  payable by Dade and its Affiliates.  Dade and its
                  Affiliates shall pay all duties, tariffs, surcharges and
                  other customs and other governmental fees levied in
                  connection with the export of the Cards outside of the
                  United States but within the Territory.
6.       Product Warranty.
         6.1      Standard Limited Warranty.  CVDI warrants that the CVDI
                  Cards, the Alliance Cards, the Dade Alliance Cards, the
                  Specialty Cards, and the Specialty Products and Controls
                  shall, at the time of shipment, (a) comply with the
                  requirements of the Act, if applicable, and shall until
                  their expiration date conform to the labeling and package
                  inserts approved by CVDI; (b) will not be products that

                  are adulterated or misbranded within the meaning of the Act;
                  (c) shall have been manufactured, packaged, stored and shipped
                  in conformity with applicable GMP requirements; and (d) will
                  not be products that may not be introduced into interstate
                  commerce pursuant to applicable federal or state law. CVDI
                  warrants that all Instruments and Products (other than Cards
                  and Controls), shall, until the earlier of twenty-four (24)
                  months from shipment by CVDI or twelve (12) months after the
                  date of installation with the customer: (a) comply with the
                  requirements of the Act, if applicable, and shall conform to
                  the labeling and package inserts approved by CVDI; (b) will
                  not be products that are adulterated or misbranded within the
                  meaning of the Act; (c) shall have been manufactured,
                  packaged, stored and shipped in conformity with applicable GMP
                  requirements; and (d) will not be products that may not be
                  introduced into interstate commerce pursuant to applicable
                  federal or state law.
                  This limited warranty is contingent upon proper use of
                  a Product in the application for which such Product
                  was intended and does not cover Products that were
                  modified without CVDI's written approval, that have
                  expired, or that were improperly stored or handled. As
                  of the date of the execution of this Agreement, CVDI
                  has no knowledge that any of the Products, or the sale
                  or use of any of the Products for their intended
                  purposes infringe any intellectual property of any
                  third party.

         6.2      No Other Warranty.  EXCEPT FOR THE EXPRESS LIMITED
                  WARRANTIES SET FORTH IN SECTION 6.1 ABOVE, CVDI GRANTS
                  NO WARRANTIES FOR THE PRODUCTS, EXPRESS OR IMPLIED,
                  EITHER IN FACT OR BY OPERATION OF LAW, BY STATUTE OR
                  OTHERWISE, AND CVDI SPECIFICALLY DISCLAIMS ANY IMPLIED

                  WITH RESPECT TO ANY PRODUCTS SHALL BE LIMITED AS FOLLOWS:
                  (1) IN THE EVENT OF PRODUCT RECALLED OR NOT IN COMPLIANCE
                  WITH THE WARRANTIES SET FORTH IN THIS AGREEMENT DUE TO
                  THE FAULT OF CVDI, CVDI SHALL, AT THE REQUEST OF DADE,
                  REFUND DADE'S COST OR THE REPLACEMENT OF SUCH PRODUCT AT
                  NO COST TO DADE, ITS DISTRIBUTORS OR CUSTOMERS; (2) IN
                  ALL OTHER CIRCUMSTANCES, A REFUND OF DADE'S COST OF THE
                  CARDS OR REPAIR OR REPLACEMENT, IN ALL EVENTS WHETHER
                  UNDER (1) OR (2), AT CVDI'S SOLE DISCRETION.  EXCEPT AS
                  OTHERWISE PROVIDED HEREIN, IN NO EVENT SHALL CVDI BE
                  LIABLE FOR THE COST OF PROCUREMENT OF SUBSTITUTE PRODUCT
                  OR FOR ANY-SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES
                  FOR BREACH OF WARRANTY OR OTHERWISE.  CVDI SHALL BEAR THE
                  EXPENSE OF FREIGHT FOR ALL RETURNED GOODS.
         6.4      Card Dating.  CVDI will use best efforts to deliver all
                  CVDI Cards, Alliance Cards, Dade Alliance Cards, and
                  Specialty Cards within three (3) months of the date of
                  manufacture.  Except as otherwise provided in Exhibit
                  6.4, CVDI will use best efforts to deliver all CVDI PT
                  Cards with a minimum card dating of nine (9) months from
                  the date of receipt by Dade.  CVDI will use best efforts
                  to deliver all CVDI aPTT Cards within a minimum card
                  dating of twenty-one (21) months from date of receipt by
                  Dade.  CVDI will use best efforts to deliver all Alliance
                  Cards and Dade Alliance Cards with minimum card dating
                  the same as for the corresponding CVDI PT and aPTT Cards.
                  CVDI will use best efforts to extend the dating of CVDI
                  PT Cards, Alliance PT Cards and Dade Alliance PT Cards in
                  accordance with the time schedule set forth in Exhibit
                  6.4 hereto.
         6.5      Remedy for "Short-Dated" Cards.  To the extent that CVDI
                  delivers any CVDI Cards, Dade Alliance Cards, and

                                       26







<PAGE>



                  Alliance Cards with less than twenty-one (21) months dating at
                  the time of such delivery, CVDI agrees to replace at the
                  request of Dade all such Cards at the time of their expiration
                  at CVDI's variable cost, not to exceed US $[ ] per card FOB
                  CVDI's distribution site. CVDI agrees to adjust such variable
                  cost to reflect actual reductions in its costs of
                  manufacturing cards as CVDI's production volume increases. All
                  cards delivered to Dade with less than the three (3) month
                  dating from the date of manufacture or less than nine (9)
                  months from the date of receipt by Dade shall be returned to
                  CVDI at CVDI's cost or destroyed by Dade at CVDI's discretion
                  and expense and shall be replaced by CVDI at no cost to Dade
                  at the time of expiration. Supply of replacement CVDI Cards,
                  Alliance Cards, Dade Alliance Cards, Specialty Cards, and
                  Instruments shall not count toward Dade's minimum purchase
                  requirements.
         6.6      Assertion of Claims.  In any case where Dade expects to
                  make a claim against CVDI with respect to nonconforming
                  Product, Dade shall retain the Product for the lesser of
                  thirty (30) days or receipt of written authorization and
                  instructions of CVDI either to dispose of the Product or
                  to return the Product to CVDI.  Dade will provide CVDI
                  proof of destruction of cards when requested by CVDI.
7.       Payments for Product.
         7.1      Purchase Price.  Except as provided otherwise herein,
                  Dade or an Affiliate of Dade shall pay CVDI a purchase
                  price per CVDI Card, Alliance Card, and Dade Alliance
                  Card (the "Card Purchase Price") of US$[    ].  Except as
                  otherwise provided herein, Dade or an Affiliate of Dade
                  shall pay CVDI a purchase price per Instrument (the
                  "Instrument Purchase Price") of US$[       ].  The
                  parties shall negotiate in good faith the purchase price
                  of the Specialty Card.  Schedule 1.11 sets forth the

                  initial prices at which CVDI will sell to Dade Products other
                  than Instruments and Cards. Such prices are subject to
                  adjustment from time to time but prices shall not be increased
                  to exceed the increase in the Producer Price Index for the
                  immediately prior calendar year, such an adjustment to begin
                  not earlier than January 1, 1998.
         7.2      Dade Commitment.  Dade agrees to purchase from CVDI a
                  minimum of [       ] in the aggregate of CVDI Cards,
                  Alliance Cards, Specialty Cards, or Dade Alliance Cards
                  ("Cards"), invoiced by CVDI to Dade at a rate of not less
                  than [       ] Cards per month during January, February
                  and March, 1997; provided however, that such firm order
                  obligation shall be reduced by the amount of Specialty
                  Products sold by Dade, pursuant to the provisions of
                  Section 3.6 above, beginning ninety (90) days from the
                  date of the first sale of such Specialty Products.  Dade
                  agrees to purchase from CVDI a minimum of [
                      ( )] Instruments by December 31, 1997; provided, however,
                  that Dade shall be entitled to a credit against the minimum
                  Instrument purchase obligation for each Instrument sold by
                  CVDI and its distributors in the Territory during 1997 where
                  such Instrument is placed with a customer for any use outside
                  of the customer's operating room facilities. CVDI shall report
                  to Dade on a monthly basis the number of all such Instrument
                  sales. During 1997, if Dade's firm forecast for any month
                  after March is less than [ ] Cards for reasons other than
                  those set forth in Section 11.4(a) (i) (ii) or (iii), the
                  parties shall discuss the reasons for such forecast and
                  possible actions the parties can take to increase Dade's sales

                  such CVDI invoices shall be paid net sixty (60) days from
                  date of CVDI's invoice in US dollars.  Dade shall provide
                  CVDI with documentation of such arrangements.  Any
                  invoiced amounts not paid when due shall be subject to a

                  disclosure of Proprietary Information, including, without
                  limitation:
                  (a)      ensuring that only its employees whose duties
                           require them to possess such information have
                           access thereto; and
                  (b)      exercising at least the same degree of care that it
                           uses for its own Proprietary Information.
         8.3      Duties Upon Termination.  Except as otherwise permitted
                  under this Agreement, upon request by the disclosing
                  party after expiration or termination of this Agreement,

                                                       35

                  the other party shall either return all of such disclosing
                  party's Proprietary Information (including data, memoranda,
                  drawings and other writings and tapes and all copies thereof)
                  received or prepared by it or destroy the same, and in any
                  event shall make no further use of such Proprietary
                  Information provided, however, that counsel for the receiving
                  party may keep one copy of the Proprietary Information for
                  purposes of ascertaining the receiving party's obligations
                  pursuant to this Section 8.
         8.4      Use of Proprietary Information. During the duration of this
                  Agreement and for a period of five (5) years thereafter,
                  neither party shall use the other party's Proprietary
                  Information for any purposes, except to perform its
                  obligations hereunder.
         8.5      Injunctive Relief.  Each party acknowledges that the
                  other party would not have an adequate remedy at law for
                  breach of any of the covenants contained in this Section
                  8 and hereby consents to the enforcement of same by the
                  other party by means of temporary or permanent injunction
                  issued by any court having jurisdiction thereof and
                  further agrees that the other party shall be entitled to
                  assert any claim it may have for damages resulting from
                  the breach of such covenants in addition to seeking
                  injunctive or other relief.
9.       Indemnification.
         9.1      Indemnification by CVDI.  Subject to Dade's compliance
                  with its obligations set forth in Section 9.3 below, CVDI

                  and expenses (including, without limitation, reasonable
                  attorneys' fees and other costs of defense) (collectively
                  "Losses") attributable to, or arising out of a breach by CVDI
                  of any of CVDI's warranties, representations, covenants or
                  obligations hereunder or any claim, lawsuit or other action by
                  a third party for, breach of contract, personal injury or
                  property damage to the extent caused by a breach by CVDI of
                  this Agreement, or out of or connected with the use or sale of
                  the Product to the extent directly caused by CVDI's fault,
                  negligence or breach of any of its obligations hereunder

                  their shareholders, directors, officers, employees and
                  agents harmless from and against any and all Losses
                  attributable to, or arising out of a breach by Dade of
                  any of Dade's warranties, representations, covenants or
                  obligations hereunder, or any claim, lawsuit or other
                  action by a third party for, breach of contract, personal
                  injury or property damage to the extent caused by a
                  breach by Dade or any of its Affiliates of this
                  Agreement, or out of or connected with the use or sale of
                  the Product to the extent directly caused by Dade's
                  fault, negligence or breach of any its obligations
                  hereunder concerning the use or sale of the Product.

         9.3      Notice and Assistance.  A party (the "indemnitee") which
                  intends to claim indemnification under this Section 9
                  shall promptly notify the other party (the "indemnitor")
                  in writing of any action, claim or other matter in
                  respect of which the indemnitee or any of its employees
                  or agents intend to claim such indemnification.  The
                  indemnitee shall permit, and shall cause its employees
                  and agents to permit, the indemnitor, at its discretion,
                  to settle any such action, claim or other matter and
                  agrees to the complete control of such defense or
                  settlement by the indemnitor; provided, however, that
                  such settlement does not adversely affect the
                  indemnitee's rights hereunder or impose any obligations
                  on the indemnitee in addition to those set forth herein
                  in order for it to exercise such rights.  No such action,
                  claim or other matter shall be settled without the prior
                  written consent of the indemnitor and the indemnitor
                  shall not be responsible for any legal fees or other
                  costs incurred other than as provided herein.  At the
                  expense of the indemnitor, the indemnitee shall render
                  the indemnitor all assistance reasonably necessary in
                  defending against such claim, suit, or action.  The
                  indemnitee party shall have the right at its expense, to
                  retain separate counsel to act in an advisory capacity in
                  connection with any matter involving a claim for
                  indemnity and the indemnitor will cooperate with such
                  counsel.

         10.1     Ownership.  Except as provided herein with respect to
                  trademarks, Dade acknowledges that it does not have, nor
                  does it hereby acquire, any right, title and interest in
                  and to any patents, patent applications, trademarks or
                  other proprietary rights of CVDI owned by CVDI at the
                  time of the execution of this Agreement.  Except as
                  provided herein with respect to trademarks, CVDI
                  acknowledges that it does not have, nor does it hereby
                  acquire, any right, title and interest in and to any
                  patents, patent applications, trademarks or other
                  proprietary rights of Dade owned by Dade at the time of
                  the execution of this Agreement.
         10.2     Patent Infringement.
                  (a)      Defense.  Dade agrees that CVDI has the right to
                           defend or at CVDI's option to settle, and CVDI
                           agrees at CVDI's expense, to defend or at CVDI's
                           option to settle, each claim, suit or proceeding
                           brought against Dade or Dade's customers arising
                           out of or related to an allegation of infringement
                           of any United States patent, copyright, or
                           trademark or misappropriation of trade secrets by
                           the sale of Products sold hereunder or the use
                           thereof, subject to the limitations hereinafter set
                           forth.  CVDI shall have sole control of any such
                           action or settlement negotiations, and CVDI agrees
                           to pay, subject to the limitations hereinafter set
                           forth, any final judgment (including all pre-
                           judgment and post-judgment interest) entered
                           against Dade or Dade's customers on such issue in

                                                       39


<PAGE>
                           any such suit or proceeding defended by CVDI. Dade
                           agrees that CVDI at CVDI's sole option, shall be
                           relieved of the foregoing obligations unless Dade
                           shall notify CVDI promptly in writing of such claim,
                           suit or preceding and give CVDI authority to proceed
                           as contemplated herein, and at CVDI's expense,
                           cooperates with CVDI to settle and/or defend any such
                           claim, suit or proceeding. CVDI shall not be liable
                           for any costs or expenses incurred without CVDI's
                           written authorization.
                  (b)      Limitation.  Notwithstanding the provisions of
                           subsection 10.2(a) above, CVDI assumes no liability
                           for (i) infringements covering completed Products
                           or any composition, assembly, combination method or
                           process in which any of the Products may be used
                           but not covering Products when used alone;
                           provided, however, that such limitation shall not
                           apply where the sale or use of the Product (whether
                           or not in any composition, assembly, combination,
                           method or process) is a sale for a use or a use
                           intended or approved by CVDI; (ii) infringements
                           involving any marking or branding not applied by
                           CVDI or applied at the request of Dade; or (iii)
                           infringements involving the modification or
                           servicing of the Products, or any part thereof
                           unless such modification or servicing was performed
                           by CVDI or in accordance with CVDI's written
                           instructions or approved by CVDI.
                  (c)      THE FOREGOING PROVISIONS OF THIS SECTION 10.2 STATE
                           THE ENTIRE LIABILITY AND OBLIGATION OF CVDI AND THE

                           EXCLUSIVE REMEDY OF DADE, ITS AFFILIATES,
                           DISTRIBUTORS AND CUSTOMERS WITH RESPECT TO ANY
                           ALLEGED INFRINGEMENT OF PATENTS, COPYRIGHTS,
                           TRADEMARKS, OR OTHER INTELLECTUAL PROPERTY RIGHTS BY
                           THE PRODUCTS OR ANY PART THEREOF.
                  (d)      Patent Enforcement.  If Dade believes that a third
                           party is reasonably likely infringing CVDI's patent
                           rights in the Territory, Dade shall promptly notify
                           CVDI of that fact and shall provide to CVDI
                           reasonable evidence of any such claim based upon
                           materials available to Dade.  Upon receipt of
                           evidence satisfactory to CVDI of infringement, in
                           CVDI's sole discretion CVDI shall then have the
                           sole right to take action against such infringing
                           third party.  If CVDI fails to take commercially
                           reasonable action within two (2)months to stop such
                           infringement, and such infringement, if allowed to
                           continue, would have a substantial effect on Dade's
                           sales of the Product, Dade shall then be entitled
                           to take commercially reasonable action to stop such
                           infringement, including the filing of suit;
                           provided, that Dade shall not have such right so
                           long as CVDI is then diligently taking action
                           against at least one infringing third party in at
                           least one country in the Territory.  For purposes
                           of this Section 10.2(b), "commercially reasonable
                           action" requires at a minimum advising the
                           infringing party to cease and desist its
                           infringement.  For purposes of this Section
                           10.2(b), "substantial effect on Dade's sales of the

                                                       41


<PAGE>
                           Product" means a third party offering for sale the
                           Product or an equivalent of the Product. For purposes
                           of this Section 10.2(b), "diligently taking action"
                           means that CVDI has filed at least one patent
                           infringement lawsuit against at least one infringer
                           in at least one country. Any recovery of damages or
                           settlement amounts from any court actions or out of
                           court actions shall be divided as follows: one
                           hundred percent to cover costs of the parties until
                           expenses are reimbursed in full and thereafter
                           seventy five percent to CVDI and twenty-five percent
                           to Dade. CVDI shall have the right to settle any such
                           action. Dade shall have the right to renegotiate its
                           minimum performance obligations under Sections 7.2
                           and 7.4 to the extent they may be affected by such
                           third party sales of the Product(s) in the Territory.
                  (e)      Cooperation.  If either party takes action against
                           a third party pursuant to this Section 10.2, or if
                           a third party claims the manufacture, use or sale
                           of Product in the Territory infringes its patent or
                           other proprietary rights, the other party agrees to
                           provide reasonable assistance by supplying
                           information within its control which may assist the
                           party taking the enforcement action or defending
                           such claim.
         10.3     Distribution Rights.  CVDI hereby grants to Dade the
                  right to act as its authorized distributor in the
                  Territory to sell the Existing Products for the term of
                  this Agreement.  During the term of this Agreement CVDI

                                                       42


<PAGE>

                  shall not bring any claim or action against Dade or any of its
                  Affiliates for the infringement or misappropriation of any
                  intellectual property owned or licensed to CVDI based upon the
                  use or sale by Dade or any of its Affiliates of Products
                  pursuant to the terms and conditions of this Agreement.
11.      Term; Termination; Conversion to Non-Exclusive.
         11.1     Term.  The initial term of this Agreement shall be from
                  the Effective Date until December 31, 2001, unless terminated
                  earlier under the provisions of this Agreement. This Agreement
                  shall renew automatically for one year periods unless at least
                  one hundred eighty (180) days prior to year end, either party
                  provides to the other written notice of its intent to
                  terminate.
         11.2     Conversion to Non-Exclusive.  CVDI shall have the right
                  to convert the exclusivity of Dade's rights to sell the
                  Products and to use the Trademarks to a non-exclusive
                  distribution agreement at any time the minimum sales to
                  end users, as set forth in Section 7.4, are not met.
                  Such right shall be exercised upon at least sixty (60)
                  days' prior written notice.  Upon exercise of such
                  conversion right:
                  (a)      CVDI will not sell Alliance Cards, including cards
                           calibrated to Dade reagents, or Dade Alliance Cards,
                           except to Dade; provided, however, that if CVDI
                           exercises such conversion right in 1997, CVDI shall
                           not be limited as to any sales of cards calibrated to
                           Dade reagents; provided, however, CVDI may not sell
                           Cards bearing Dade marks except to Dade;

                  (b)      CVDI will use best efforts to honor and
                           fulfill card unit requirements contained in
                           existing customer agreements of Dade; and
                  (c)      CVDI will not sell Specialty Cards using or including
                           that which the parties agree is Dade's proprietary
                           technology in accordance with Section 4.3 or Dade
                           Alliance Cards except to Dade;
                  (d)      CVDI will be free to negotiate distribution
                           agreements in the Territory; and
                  (e)      Dade's obligations to make further payments
                           pursuant to Section 4.2 hereof shall cease.
                  In the event of such conversion, CVDI and Dade shall negotiate
                  annual volumes of Cards and the price for the same on a year
                  to year basis; provided, however, that price levels shall not
                  exceed the pricing structure included in this Agreement to the
                  extent that Dade's sales volume meets any of the volume
                  discounts described in Section 7.3, adjusted by the Producer
                  Price Index as it may change from time to time and, provided,
                  however, that the minimum volumes shall be less than those
                  required to maintain exclusivity. CVDI shall be entitled to
                  terminate this Agreement in event that the negotiated minimum
                  volumes shall be less than those stated in Section 7.4(c).
                  Dade agrees to submit an annual sales volume plan to CVDI.
                  Beginning thirty (30) days subsequent to such conversion, Dade
                  shall provide quarterly its Forecast of requirements for the
                  Cards for each of the six (6) months following the end of the
                  quarter in which such forecast is submitted. The monthly sales
                  quantities shown in the Forecast for the first

         11.3     Termination for Cause -- Either Party.  Without prejudice
                  to any other rights it may have hereunder or at law or in
                  equity, either party may terminate this Agreement

                           import;
                  (b)      the other party makes an assignment for the benefit

                           appointed for it or its business is placed under
                           attachment, garnishment or other process involving a
                           significant portion of its business;
                  (c)      after sixty (60) days' written notice from the

                           party not involving minimum sales or payments;
                  (d)      the failure by Dade to make any payment due under

                           in Section 7.3;
                  (e)      the failure by Dade to maintain sales to end users

                  (a)      In the event that CVDI cannot meet (i) its delivery
                           of Product obligations consistent with the
                           provisions of Section 5.7(c); (ii) the delivery of

                           Dade's obligation to fund research and development
                           under Section 4.2 shall be waived for the period of
                           non-performance by CVDI.  If at the end of the

                           has not cured deficiencies in all obligations in
                           which it is in default, then: (x) for each
                           following month in which CVDI remains in default,

                           the minimum sales necessary to prevent termination
                           of this Agreement by CVDI pursuant to Section 7.4,
                           and if Dade fails to meet the minimums stated in
                           Section 7.4(c) within such timeframe, CVDI shall be
                           entitled to terminate this Agreement; or (y) Dade

                           4.2 shall be reinstated for the full balance of any
                           such obligations beginning ninety (90) days
                           subsequent to any such cure.
                  (b)      In the event that Dade does not fulfill its
                           obligations under Section 7.4 and CVDI elects to
                           change the Agreement to a non-exclusive basis, Dade
                           shall have the right upon ninety (90) days advance

                           shall not affect any rights or obligations accrued by
                           either party prior to the effective date of
                           termination, including under any purchase order for

                  (b)      Except as provided otherwise in this Section 11.5,
                           upon termination of the Agreement, CVDI shall use

                           Products to Dade and its Affiliates in such
                           quantities as ordered but in quantities no greater
                           than reasonably appropriate in connection with:
                           (a) fulfilling contractual commitments to customers
                           of Dade, its Affiliates and its subdistributors for

                           not to exceed thirty-six (36) months.  Prices for

                           increases/decreases in material, labor, and
                           reasonable overhead. Upon termination of this
                           Agreement, and to the extent permitted under
                           applicable law, in each and every case for a price
                           paid by CVDI equal to the cost and expense incurred
                           by Dade and its Affiliates to obtain such approvals
                           and registrations, Dade, upon CVDI's request, shall
                           assign to CVDI (or such other entities designated by
                           CVDI) all product approvals, registrations and
                           regulatory approvals to sell Products in each country
                           in the Territory; or, if assignment of any such
                           registration or approval is not permissible under
                           applicable law, where requested by CVDI, Dade shall
                           grant CVDI (or its designee) a right of reference to
                           such registrations and approvals. Dade shall
                           otherwise use reasonable efforts to enable CVDI to
                           import and sell the Products in such countries.
                  (c)      At Dade's discretion, Dade may continue to sell
                           Instruments or return them, unsold by Dade, to
                           CVDI.  If Dade returns the unsold Instruments to
                           CVDI, and for all unsold Instruments purchased by
                           Dade pursuant to Section 7.2, CVDI agrees to
                           repurchase from Dade all such Instruments at the
                           price which Dade purchased such Instruments less a
                           twenty percent (20%) restocking fee.
                  (d)      Upon termination of this Agreement by Dade, CVDI will
                           not sell cards bearing Dade marks except to Dade.

                           sell, except to Dade, the Specialty Card using or
                           including that which the parties agree is Dade's
                           proprietary technology in accordance with Section 4.3
                           nor Dade Alliance Cards.
                  (f)      Sections of this Agreement shall survive any
                           termination of this Agreement which relate to
                           confidentiality and indemnification, or otherwise
                           which by their nature cannot be accomplished or
                           fulfilled prior to termination or which relate to
                           obligations of the parties accrued prior to
                           termination.

                  terminated prior to October 15, 1997, as a result of the
                  failure by CVDI to deliver the Alliance Card in
                  accordance with the terms of Schedule 4.2 or the Dade
                  Alliance [      ] Card (if Dade has funded the Dade
                  Alliance [      ] Card project) in accordance with the
                  terms of Schedule 4.2, or the failure by CVDI to deliver
                  to Forecast as set forth in Section 5.7(c), CVDI shall
                  refund to Dade all research and development funds paid by

                  projects.

         or arising from any alleged wrongful conduct or omission related to
         this Agreement, may upon mutual agreement of the parties, be determined
         by arbitration. The arbitration shall be conducted in accordance with

         for purposes of this Agreement (1) preliminary injunctions,
         appointments of receivers, attachments, temporary protective
         orders and writs of possession constitute "provisional
         remedies," and (2) judicial actions to enforce a decision
         reached pursuant to this section constitute "ancillary

                  or to such other address as the addressee may have specified
                  in notice duly given to the sender as provided herein. Such
                  notice, request, demand, waiver, consent, approval or other
                  communications will be deemed to have been given as of the
                  date so delivered, transmitted by facsimile or fifteen (15)
                  days after so mailed.
         13.3     Severability.  In the event that any provision of this
                  Agreement shall be found in any jurisdiction to be in
                  violation of public policy or illegal or unenforceable in
                  law or equity, such finding shall in no event invalidate
                  any other provision of this Agreement in that
                  jurisdiction, and this Agreement shall be deemed amended
                  to the minimum extent required to comply with the law of
                  such jurisdiction.
         13.4     Entire Agreement. This Agreement states the entire agreement
                  between the parties hereto about the transactions contemplated
                  hereby and may not be amended or modified except by written
                  instrument duly executed by the parties hereto.
         13.5     No waiver. The failure of either party hereto to enforce at
                  any time, or for any period of time, any provision of this
                  Agreement shall not be construed as a waiver of such provision
                  or of the right of such party thereafter to enforce each and
                  every provision.

         13.6     Assignment, Binding Effect.  Neither party shall assign
                  this Agreement nor any of their respective rights or
                  obligations hereunder without the prior written consent
                  of the other party, except that either party may assign
                  this Agreement to any of its Affiliates or to any person
                  to which substantially all of the assets comprising its
                  hemostasis products business are transferred by operation
                  of law or otherwise, including, but without limitation,
                  by merger or transfer of stock.  Any other attempted
                  assignment without such consent shall be void.  Any
                  assignee or transferee of this Agreement and/or the
                  rights or obligations hereunder shall expressly assume in
                  writing all obligations of the assignor/transferor
                  pursuant to this Agreement.  In performing this
                  Agreement, Dade may, upon sixty (60) days advance written
                  notice, delegate to its Affiliates or Allegiance its
                  obligations hereunder.  Dade shall remain primarily
                  liable to CVDI despite such delegation.
         13.7     Independent Contractor.  Each party shall act as the
                  independent contractor of the other party.  Neither party
                  shall be the legal agent of the other for any purpose
                  whatsoever and therefore has no right or authority to
                  make or underwrite any promise, warranty or
                  representation, to execute any contract or otherwise to
                  assume any obligation or responsibility in the name of or
                  in behalf of the other party, except to the extent
                  specifically authorized in writing by the other party.
                  Neither of the parties hereto shall be bound by or liable
                  to any third persons for any act or for any obligation or
                  debt incurred by the other toward such third party,

                                                       53


<PAGE>

                  except to the extent specifically agreed to in writing by
                  the party so to be bound.
         13.8     Headings. All section headings contained in this Agreement are
                  for convenience of reference only, do not form a part of this
                  Agreement and shall not affect in any way the meaning or
                  interpretation of this Agreement.
         13.9     Counterparts.  This Agreement may be executed in any
                  number of counterparts and any party hereto may execute
                  any such counterpart, each of which when executed and
                  delivered shall be deemed to be an original and all of
                  which counterparts taken together shall constitute but
                  one and the same instrument.  It shall not be necessary
                  in making proof of this Agreement or any counterpart
                  hereof to account for any of the other counterpart.
        13.10     Force Majeure.  Neither party shall be deemed to be in
                  default for failure or delay in performance to the extent
                  of causes which are reasonably unforeseeable or, if
                  foreseeable, reasonably unremediable in spite of diligent
                  efforts to effect a reasonable remedy, and which are
                  caused by act or omission of any governmental authority
                  or of the other party, compliance with new governmental
                  regulations, insurrection, riot, embargo, delays or
                  shortages in transportation or inability to obtain
                  necessary materials, and Acts of God or Nature.
        13.11     Insurance.  CVDI and Dade shall at all times maintain
                  insurance, including product liability insurance, in the
                  amount of $5,000,000.00.  Each party shall, at the
                  request of the other party, provide such evidence of such
                  insurance as requested, including a certificate of

                                                       54

                  insurance. Such insurance shall not be canceled without at
                  least thirty (30) days prior written notice to Dade.
        13.12     Books and Records.  CVDI and Dade shall, during the term
                  of this Agreement and for three (3) years thereafter,
                  make and keep full and accurate books and records showing
                  the quantities of Products sold in sufficient detail to
                  determine applicable pricing pursuant to Section 7.3, the
                  maintenance of exclusivity pursuant to Section 7.4, and
                  applicable Card, commission, and Instrument credits
                  pursuant to Sections 3.6, 5.6, 5.7, and 7.2.  Each party
                  shall be permitted to designate an independent third
                  party such as a nationally recognized "Big Six"
                  accounting firm to inspect the applicable books and
                  records of the other party from time to time, during
                  regular business hours to the extent necessary to verify
                  applicable pricing and credits.  The designated party
                  shall report its findings to the requesting party.  Each
                  party agrees to treat as Proprietary Information all
                  information learned in the course of any such


                                                       55

                  inspection hereunder, except when it is necessary for the
                  party to reveal such information in order to enforce its
                  rights under this Agreement. Notwithstanding anything to the
                  contrary contained herein, the party to be inspected may waive
                  at any time the requirement contained in this section relating
                  to the use of an independent third party.
        13.13     Press Releases; Publicity.  Neither party shall publicly
                  disclose or announce any term of this Agreement;
                  provided, however, that a party may issue a press release
                  disclosing the existence of this Agreement and other
                  terms only upon prior written agreement of the other
                  party, further provided, that each party shall at all
                  times be entitled to make disclosures required by
                  applicable securities laws.

         IN WITNESS WHEREOF, this Agreement has been duly executed and delivered
