                                     PART I

ITEM 1.  DESCRIPTION OF BUSINESS

SeraCare, Inc. (""SeraCare" or the "Company") was incorporated under the laws 
of the State of Delaware in 1986 and changed its name from American Blood 
Institute, Inc. to SeraCare, Inc. effective February 6, 1996.  The Company 
maintains its principal business and executive offices at 1925 Century Park 
East, Suite 1970, Los Angeles, California 90967, telephone (310) 772-7777.

The business of the Company is conducted through its four wholly-owned 
subsidiaries: AVRE, Inc., a Nevada corporation, Binary Associates, Inc., a 
Colorado corporation, BHM, Inc., an Arkansas corporation, and SeraCare 
Acquisitions, Inc., a Nevada corporation.  SeraCare was  initially engaged in 
the business of  whole blood collection and distribution on a "for profit" 
basis. After significant and accelerating losses, the SeraCare Board of 
Directors brought in a new management team in 1993 to do an in-depth analysis 
of the business and to formulate and implement corrective measures.  After 
completing the analysis, the Board determined to discontinue the whole blood 
operations and to change the focus of the business  to the more profitable 
plasma collection business. Accordingly, the Company designed a restructuring 
plan, obtained financing and on October 4, 1993 acquired AVRE, Inc. and 
Binary Associates, Inc. (which together owned and operated six plasma 
collection centers) to form the basic platform for the future focus of the 
Company.  Before implementing the restructuring plan for the Company,  
management met with both secured and unsecured creditors and obtained their 
support and cooperation. However, one secured lender subsequently called a 
default and attempted to foreclose on the six plasma collection centers.  The 
Company filed for protection under Chapter 11 of the Bankruptcy Code on 
January 7, 1994 in order to prevent the foreclosure. 

The Company emerged from Chapter 11 effective  February 6, 1996 as a plasma 
collection company with six plasma collection centers.  On July 2, 1996, the 
Company acquired the operating assets and licenses of Silver State Plasma 
Center in Las Vegas, Nevada from Nations Biologics in an asset purchase.  On 
July 8, 1996 the Company acquired BHM Labs, Inc., which owns and operates a 
plasma collection center in Ft. Smith, Arkansas. Effective September 1, 1996, 
the Company completed the acquisition two initial stage plasma collection 
centers in Clearfield, Utah and Raleigh, North Carolina.  The Company has also 
signed leases in preparation for starting  new plasma centers in three other 
locations. 

The plasma centers are operating under the tradename "SeraCare," which is 
registered with the United States  Patent and Trademark Office. 

COMPETITION 

The Company competes for donors with pharmaceutical companies which collect 
plasma for their own use,  several other commercial plasma collection 
companies, and non-profit organizations, such as the American Red Cross and 
community blood banks, which solicit the donation of whole blood. A number of 
these competitors have access to greater financial, marketing and other 
resources than the Company. If the Company is unable to maintain and expand 
its donor base, its business and future prospects will be adversely affected. 

Most of the plasma which the Company  sells to its customers is sold under 
long-term contracts and relationships which once established continue to be 
renewed. The plasma collected by the Company is generally used in the 
manufacture of therapeutic products to treat certain diseases. Several 
companies are attempting to develop and market products to treat these 
diseases based upon technology which would lessen or eliminate the need for 
human blood plasma. Such 

                                        2

<PAGE>

products, if successfully developed and marketed, could adversely affect the 
demand for plasma. Products utilizing technology developed to date have not 
yet proven as cost-effective or as marketable to healthcare providers as 
products based on human blood plasma. However, there can be no assurances that 
such technology will not ultimately become economically viable and cause a 
severe adverse impact upon the Company and the plasma industry as a whole. 

REGULATORY ISSUES 

The plasma collection and derivative industry is one of the most heavily 
regulated in the U.S.  Federal, state and local regulations are designed to 
protect the health of the donors as well as the integrity of the products.  
The Food and Drug Administration (the "FDA") administers the federal 
regulations across the country.  Failure to comply with FDA regulations, or 
state and local regulations, may result in the forced closure of a collection 
center or monetary fines or both, depending upon the issues involved.  A 
number of blood banks and plasma centers in the U.S. have been closed because 
of legal actions taken by the FDA. The Company is also subject to regulation  
by Occupational Safety and Health Administration ("OSHA"). 

The American Blood Resources Association ("ABRA"), an industry organization, 
has developed and adopted an industry-wide program to certify those plasma 
centers meeting or exceeding standards  which it determines are in the best 
interest of the industry, donors and the public. Within the past five years, 
ABRA has created a higher level of performance criteria and implemented this 
certification process, which has upgraded the image of the U.S. plasma 
collection industry. Examples of the requirements which are enforced by the 
FDA, state authorities and ABRA include facilities upgrade, high operating 
standards, strict donor screening for drugs and disease, verified addresses 
for all donors, use of a national registry of deferred donors and controlled 
viral reactive rates to insure they remain within prescribed limits.  The 
Quality Plasma Program ("QPP") is designed to eliminate the collection of 
plasma from donors who are homeless, transient or drug addicted. In addition, 
it requires all certified centers to maintain documented and approved 
employee-training programs. All testing required by the center must be 
performed in a QPP-approved laboratory. All eight of the Company's current 
centers have been QPP-certified. In addition, the Company's startup centers 
and initial stage centers have been designed and planned to QPP 
specifications. 

The Company's management closely monitors compliance with applicable 
governmental regulations,  ABRA standards imposed through  QPP  and the 
Company's own quality assurance standards.

                         THE INDUSTRY AND THE MARKET

THE PRODUCT

Currently, the Company's primary product is "source plasma." Source plasma is 
plasma collected from humans. Plasma is the liquid part of blood and is 
collected through a procedure similar to giving blood.  The clear plasma is 
mechanically separated from the cellular elements of the blood (such as red 
and white blood cells and platelets) through centrifugation or membrane 
filtration at the time the donation is made.  These cellular elements are then 
returned to the donor as part of the same procedure.  The process of 
collecting plasma is known as PLASMAPHERESIS. Because blood cells are 
returned, it is possible for individuals to donate plasma more frequently than 
 whole blood.  Donations of plasma  can  be made up to twice per week or 104 
times per year pursuant to FDA rules.

                          PLASMA PRODUCTS FLOWCHART

                                  [GRAPHIC]


PLASMA DERIVED PRODUCTS

Source plasma is sold to fractionators who process the plasma into two primary 
groups of plasma products: INJECTABLE AND NON-INJECTABLE.  These products are 
used  throughout  the world  to  prevent  illness  and treat injuries.

During the fractionation process, the various protein components of plasma are 
separated and purified so they can be infused into patients at concentrations 
much higher than in the liquid source plasma from which they are derived. The 
fractionators process the collected plasma through two sterilization processes 
which are designed to kill any bacterial or viral occurrences. Because of the 
commingling of plasma from various suppliers and the two sterilization 
procedures included in the process, the fractionators bear substantially all 
legal risks for the quality of plasma received by end users.  SeraCare has 
almost no legal risk because no plasma sold by SeraCare is sold to end users 
as plasma. 

INJECTABLE PLASMA PRODUCTS

SOURCE PLASMA is the base raw material used to manufacture many injectable
therapeutic products, the most important of which are:

  NORMAL SERUM ALBUMIN AND PLASMA PROTEIN FRACTION, which are primarily used to
  keep vessel walls from collapsing following major injury, as blood volume
  expanders and as a protein replacement.  They are used:

          -  to treat shock due to trauma or hemorrhage;

          -  to treat fluid loss due to severe burns;

          -  in cardiovascular surgery;

                                        4

<PAGE>

          -  to treat liver and kidney diseases; and

          -  as a carrier for many other injectable solutions.

  IMMUNE GLOBULINS, which are used to strengthen the immune system in order to 
  fight off  common diseases such as:

          -  Suppressed immune systems in cases of organ transplants, HIV and
             other immune deficiencies;

          -  Hepatitis B;

          -  Tetanus;

          -  Rabies, whooping cough, measles and polio; and

          -  Other immune related diseases.

  ANTIHEMOPHILIC FACTORS, which are specific proteins found in plasma that are
  an integral part of the blood clotting mechanism. Persons born with an
  absence or a deficient amount of the protein suffer from hemophilia, types A,
  B, or Von Willebrand's Disease.

  RH IMMUNE GLOBULIN, which is a substance administered to prevent 
  incompatibilities between the blood of a fetus and mother. Its use has
  prevented the deaths of thousands of infants.

NON-INJECTABLE PLASMA PRODUCTS

The secondary use of plasma is to manufacture certain diagnostic products which
are for the most part non- injectable. Some of the primary diagnostic products
are:

          -    BLOOD GROUPING AND TYPING REAGENTS which are used by blood banks
               to match donor blood with the recipient.

          -    LABORATORY CONTROL REAGENTS which are used by  laboratories to 
               assure the quality control of their tests.

          -    SPECIAL TEST KIT REAGENTS which are derived from the plasma of 
               donors known to have a specific disease and are used in the 
               laboratory as a positive control test.

SPECIALTY PLASMAS

Specialty Plasmas generally contain high concentrations of specific antibodies 
and are used primarily to manufacture immune globulin therapeutic products 
which bolster the immunity of patients to fight a particular infection or to 
treat certain immune system disorders. Following advances in intravenous 
therapy in the mid-1980s, use of specialty plasmas for therapeutic purposes 
significantly increased. Among the current uses for specialty plasmas are the 
production of products to prevent hepatitis, Rh incompatibility in newborns, 
tetanus and rabies. Specialty plasmas are also widely used for diagnostic and 
tissue culture purposes. Depending on the rarity of the antibody or medical 
history of the donor, the pricing for specialty plasmas currently ranges from 
$80 to $3,500 per liter. The average spot price (free market price) of source 
plasma is currently approximately $76.  Most specialty plasma is derived 
serendipitously (not the result of stimulation) which poses no abnormal risk 
to the plasma collector. 

The Company currently collects and sells two specialty plasmas, Cytomegalovirus
Antibody Plasma (CMV) and Tetanus Antibody Plasma. The Company intends to place
increased emphasis 

                                        5

<PAGE>

on the collection of specialty plasmas by identifying potential specialty 
plasma donors through screening and testing procedures and by developing more 
FDA-licensed programs to inoculate potential donors.

                               THE PLASMA INDUSTRY

The blood resource industry can be divided into two industry segments.  One is 
the non-profit or voluntary sector which is commonly thought of as Red Cross 
and independent non-profit blood centers. This "non-profit" sector is 
primarily concerned with providing whole blood and components of whole blood 
for transfusion in medical applications at hospitals. The other is the 
commercial or "for-profit" segment such as plasma collection centers. This 
"for-profit" commercial sector consists of plasma collection operations which 
collect plasma from paid donors and sell the  plasma to Fractionators, who  
produce plasma derivative products or fractions that are used in therapeutics.

The following table shows certain plasma collection data for the years 1977
through 1993.

Plasma is collected at centers owned by both foreign and U.S. fractionators 
and by independent companies who sell to diagnostic companies and other 
fractionators.

Plasma collection centers are found in most states throughout the United 
States as presented in the following illustration:

            DISTRIBUTION OF PLASMA CENTERS BY STATE - 1993

                                [GRAPHIC]

     SOURCE: AMERICAN BLOOD RESOURCES ASSOCIATION

The United States plays a leading role in the world's source plasma,  
providing approximately 65% of the world's plasma needs. The United States 
plasma industry has made a concerted effort through ABRA to increase its 
global market share.

PLASMA MARKET

The source plasma industry has experienced a number of fluctuations in the 
supply and demand cycles. The market factors driving the plasma industry have 
included: 

       -   The expanded use of immune globulins to prevent and treat disease.

       -   The worldwide plasma shortage.

       -   Extensive public concern over the safety of blood products.

       -   An increase in domestic and foreign regulatory control over the
           collection and testing of plasma.  

A worldwide shortage of plasma began in 1991, driven partially by the 
increased need for plasma components to treat larger and older populations, 
and partially by a diminished pool of donors that resulted from more 
restrictive testing and screening requirements imposed by regulatory 
authorities. In 1991, the FDA required mandatory screening for hepatitis C, 
thereby disqualifying donations from a significant portion of the then 
existing donor base. Another market factor has been increasing public concern 
over HIV and other viruses which has lead to increased testing and tighter 
scrutiny.

The Company has generally sold its plasma under contracts ranging from one to 
three years which allow for annual pricing renegotiations. Pricing for product 
deliveries is generally mutually agreed to prior to the beginning of the 
contract year and fixed for that year. Consequently, the Company may be 
adversely or beneficially affected if its costs of collecting and selling 
plasma rise or fall during the year as a result of changes in government 
regulation, donor fees  or other factors.

FRACTIONATORS

Fractionation is the process of separating the raw source plasma into a variety
of derivative products (see "The Product"  above).  Prior to being fractionated,
source plasma is blended into batches of 7,500 to 10,000 liter units from many
different donor sources.

                                        7

                              CURRENT OPERATIONS

CURRENT PLASMA CENTERS

The Company currently owns and  operates eight plasma centers at the following 
locations: Las Vegas, Nevada (2 centers); Phoenix, Arizona; Colorado Springs, 
Colorado (2 centers); Pueblo, Colorado;  Clarksville, Tennessee; and Ft. 
Smith, Arkansas.  Two initial stage centers in Clearfield, Utah and Raleigh, 
North Carolina will be operational by November 15, 1996.  The Company has also 
negotiated leases in three additional locations for startup centers, one of 
which will be operational by November 15, 1996.  Four startup centers 
(including the three for which leases have already been negotiated) are 
expected to be operational by January 1997, bringing the total number of 
operating centers to fourteen.  

The Company collected approximately 105,000 liters of plasma in calendar year 
1995, with the initial six centers.  This represented an 11%, or approximately 
10,000 liter, increase over 1994 and a 33% increase over 1993.  The current 
eight operational centers are collecting plasma at the rate of approximately 
165,000 liters annually. Approximately 90% percent of this plasma is currently 
sold under contracts with Alpha Therapeutic Corporation, a subsidiary of the 
Green Cross Corporation of Japan. Alpha Therapeutic is one of the major 
companies in the plasma collection, fractionation and product distribution 
business in the  United States. Approximately 10% of the Company's collected 
plasma is currently sold as Hyperimmune plasma (CMV) to another domestic 
customer.

DONORS

FDA standards restrict the frequency in which a donor may give plasma to twice 
a week or 104 times per year.  Most regular donors donate between 40 and 60 
times per year.

The QPP certification program attempts to exclude drug or alcohol addicts or 
homeless persons by requiring proof of permanent address as well as alcohol 
and drug use testing.

MARKETING/DONOR RECRUITMENT

Effective recruitment, management and retention of donors are essential to the 
Company's plasma business. The Company seeks to attract and retain its donor 
base in the following ways: 

                                        8

<PAGE>

        -   by utilizing competitive financial incentives which the Company 
            offers for the donation of the plasma. 

        -   by providing outstanding customer service to its donors. 

        -   by implementing programs designed to attract donors through 
            education as to the uses of plasma. 

        -   by encouraging regular participation in its donor programs.

        -   by providing incentives to encourage donors to return. 

Repeat donors are important because of the lower cost associated with 
obtaining their plasma and less risk that their plasma will not satisfy 
regulatory and customer requirements. The Company's centers advertise for 
donors through targeted mailings, flyers and newspapers. Radio and television 
ads are also used when advantageous.

The Company's donor records are maintained with the assistance of donor 
database systems at each center which allows the Company's personnel to track 
the frequency of donor visits. When a donor has not visited a center in over 
one month, the center sends a reminder card to the donor emphasizing the 
importance of the donor's continued participation.

DONOR PROCESSING

On their first visit all new donors are given a physical examination by either 
a licensed physician or physician substitute. The National Donor Deferral 
Registry and the  deferral lists of the Fractionators and other local plasma 
centers are all checked to determine if the donor has ever had positive viral 
test results or has ever been previously deferred or rejected as a donor. In 
addition to the deferral list checks,  each time the donor visits, the donor 
is given the opportunity to defer himself confidentially and is asked a number 
of screening questions which he must audibly answer. In addition, each time he 
visits, the donor is tested for: blood pressure; temperature; pulse; weight; 
hematocrit; total proteins; HIV; hepatitis B and C; and liver enzymes.

QUALITY AND OPERATIONAL CONTROLS

Through its QPP and internal operating procedures and policies, the Company 
strives to maintain the highest level of quality control. Donor charts are 
audited on a daily basis, and all equipment is regularly recalibrated. Routine 
double and triple checks of the donor processing are performed at every level. 
The quality control procedures are kept at a detailed level.  The centers also 
are routinely inspected on an unannounced basis for quality control by the 
FDA, the state regulatory authorities, CLIA (Clinical Laboratories Improvement 
Act) and the contracted  fractionators.

TRAINING

The Company is focusing on two levels of training: (a) technical training of 
employees; and (b) center management skills and development.

All employees are required to read and study detailed training materials and 
are then given a written test covering that material. Results of the written 
tests must be kept available for FDA inspection. Employees are also required 
to demonstrate specific skills to an FDA-certified trainer. Each level of an 
employee's training is tracked and documented and each employee is required to 
be retested on all  material every six months. All employees are "cross 
trained" in all three of the center's functional areas, allowing for more 
efficient scheduling. Ongoing or continuing education sessions are 
periodically held to review new procedures, equipment and FDA requirements. 
All training documentation is subject to FDA approval.

It is the Company's philosophy to continually develop competent individuals 
within the Company to move into management positions. Selected individuals are 
sent to outside management development seminars in addition to the in-house 
program of development. Consequently, all of the open manager positions during 
the past three years have been filled with existing in-house personnel.

EMPLOYEES

The Company employed approximately 150 persons as of September 30, 1996. 
Because many of the employees work on a part-time basis,  total headcount 
represents approximately 98 full time equivalents. The Company believes that 
the relations between the Company's management and its employees are good, 
although there can be no assurances that such relations will continue. The 
inability of the Company to attract or retain qualified personnel could have a 
material adverse effect on the Company. 

ITEM 2. PROPERTIES

The Company currently occupies nine locations with corporate offices at 1925 
Century Park East, Suite 1970, in Los Angeles and eight plasma centers in: Las 
Vegas, Nevada (2 centers); Clarksville, Tennessee; Phoenix, Arizona; Colorado 
Springs, Colorado (2 centers); Pueblo, Colorado; and Ft. Smith, Arkansas.  In 
September, 1996 the Company acquired leases in Clearfield, Utah and Raleigh, 
North Carolina  in connection with the acquisition of two initial stage 
collection centers which the Company expects will be operational by November 
15, 1996. In addition, the Company has signed leases in Pasco, Washington, 
Toledo, Ohio, and Macon, Georgia in preparation for starting new centers in 
those locations.  All of the Company's leased property, comprising fourteen 
locations and approximately 57,000 square feet, is leased from unaffiliated 
parties under leases expiring through 2002. Most of these leases contain 
renewal options which permit the Company to renew the leases for periods of 
from two to five years at the then fair rental value. Two of the Company's 
centers are leased on a month-to-month basis. The Company believes that in the 
normal course of its business it will be able to renew or replace its existing 
leases. The Company believes that the space it occupies is adequate for its 
existing centers.

The Company's plasma collection centers range in size from approximately 2,950 
to 5,500 square feet and generally are located in population centers of 80,000 
to 1,000,000 people.

time, the Company does not expect to declare or issue any dividends within the

the terms of the Plan of Reorganization, total recoveries of preference claims
net of legal costs are to be split one-half to the Unsecured Creditors on a pro-

INDEPENDENT AUDITORS' REPORT



The Board of Directors 
SeraCare, Inc.

We have audited the accompanying consolidated balance sheet of SeraCare, Inc.
(Restructured Company) and subsidiaries as of February 29, 1996 and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for the period February 6, 1996 to February 29, 1996. We have also audited
the consolidated balance sheet of American Blood Institute, Inc. (Predecessor
Company) (Debtor-In-Possession) and subsidiaries as of February 28, 1995 and the
related consolidated statements of operations, stockholders' equity (deficit)
and cash flows for the period March 1, 1995 to February 5, 1996 and the year
ended February 28, 1995. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the financial
statements. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of SeraCare, Inc.
(Restructured Company) and subsidiaries and American Blood Institute, Inc.
(Predecessor Company) and subsidiaries at February 29, 1996 and February 28,
1995 and the results of their operations and their cash flows for the periods
ended February 29, 1996 and February 5, 1996 and the year ended February 28,
1995, in conformity with generally accepted accounting principles.

As discussed in Note 1 to the financial statements, the Bankruptcy Court 
confirmed the Company's Plan of Reorganization on January 24, 1996, and the 
Company emerged from bankruptcy effective February 6, 1996. On February 6, 
1996 the Company accounted for the reorganization and adopted "fresh start 
accounting." As a result, the Company's February 29, 1996 financial 
statements are not comparable to the February 28, 1995 financial statements, 
since they present the financial position and results of operations of the 
reorganized entity.

                                                  SUMMARY OF ACCOUNTING POLICIES


- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

ORGANIZATION

SeraCare, Inc. (formerly American Blood Institute, Inc.) (the "Company"), a
Delaware corporation, was formed on November 8, 1991. The business of the
Company is currently carried out through its two wholly-owned subsidiaries AVRE,
Inc., a Nevada corporation, and Binary Associates, Inc., a Colorado corporation.

BUSINESS OPERATIONS

The Company was initially engaged in the business of whole blood collection and
distribution. After significant and accelerating losses, it changed the focus of
the business from whole blood to plasma collection and distribution. On October
4, 1993, the Company acquired 100% of the outstanding common stock shares of
AVRE, Inc. and Binary Associates, Inc., which owned and operated six plasma
collection centers. On January 7, 1994, the Company and subsidiaries filed for
protection under Chapter 11 of the Bankruptcy Code. The restructuring plan
which was implemented encompassed the following actions: renegotiating all
plasma sales contracts to Fractionators; developing marketing strategies
including demographic studies and donor pricing analyses for each of its six
plasma centers; reorganizing the management structure of the Company by moving
the headquarters to Los Angeles, discontinuing regional manager positions and
changing three of the six center managers; obtaining Quality Plasma Program
("QPP") certification from the American Blood Resources Association for all six
centers; and establishing consistent strategies, policies and procedures in
order to compete in the emerging QPP plasma industry. The restructuring of the
six plasma operations is substantially complete. The Company emerged from
Chapter 11 effective February 6, 1996. The six plasma centers currently operate
under the tradename "SeraCare". The name "SeraCare" is registered with the
United States Patent and Trademark Office.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its two wholly owned subsidiaries. All significant intercompany transactions and
balances have been eliminated in consolidation.

INVENTORIES

Inventories are stated at the lower of cost which is determined on a first-in,
first-out basis, or market. Inventories consist of blood plasma collected from
donors and medical supplies.


                                                                            FS-9

                                                  SUMMARY OF ACCOUNTING POLICIES



- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciation and amortization are
computed primarily using the straight-line method over the estimated useful
lives, which range from three to seven years.

INCOME TAXES

The Company utilizes FAS 109 "Accounting for Income Taxes" in accounting for
income taxes. It requires an asset and liability approach for financial
accounting and reporting of deferred income taxes. Generally, FAS 109 allows for
recognition of deferred tax assets in the current period for the future benefit
of net operating loss carryforwards and items for which expenses have been
recognized for financial statement purposes but will be deductible in future
periods. A valuation allowance is recognized, if on the weight of available
evidence it is more likely than not that some portion or all of the deferred tax
asset will not be realized.

CASH AND CASH EQUIVALENTS

For purposes of the statement of cash flows, the Company considers all highly
liquid debt instruments with an original maturity of three months or less to be
cash equivalents.

REORGANIZATION VALUE IN EXCESS OF AMOUNTS ALLOCABLE TO IDENTIFIABLE ASSETS

Under the principles of "fresh-start" reporting, the Company allocated total
reorganization value among identifiable tangible and intangible assets on the
basis of their estimated fair values. The remaining amount is classified as
reorganization value in excess of amounts allocable to identifiable assets and
is being amortized over twenty years.

FDA LICENSES

The reorganization value allocated to Food and Drug Administration ("FDA")
licenses represents the estimated value of a valid FDA license necessary to
operate a plasma donor center in the United States. An estimate value of
$150,000 per center has been allocated to the six centers owned by the Company.
The FDA license value is being amortized over forty years.


                                                                           FS-10

- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

DONOR BASE AND RECORDS

The reorganization value allocated to donor base and records represents the
estimated value to acquire a plasma center donor base and records. An estimated
value of $100,000 per center has been allocated to the six centers owned by the
Company. The donor base and records is being amortized over twenty years.

EXCESS OF COST OVER NET ASSETS ACQUIRED

Prior to February 6, 1996, the excess cost over net assets acquired represented
the excess of amounts paid over the fair value of net assets acquired relating
to the acquisitions of AVRE, Inc. and Binary Associates, Inc., and was being
amortized over forty years. The unamortized balance was written off in
connection with the Restructuring.

ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

FAIR VALUE OF LONG-TERM DEBT

The fair value of the Company's long-term debt is estimated based on the quoted
market prices for the same or similar issues or on the current rates offered to
the Company for debt of the same remaining maturities.

1. REORGANIZATION AND BASIS OF REPORTING

During 1994 and 1995 the Company prepared and has completed a plan of
reorganization (the "Plan") pursuant to Chapter 11 of the U.S. Bankruptcy Code.
The Company filed the Plan with the U.S. Bankruptcy Court for the Central
District of California (the "Bankruptcy Court") on January 24, 1996 ("the
Petition Date"). The Plan was confirmed by the Bankruptcy Court and the Company
emerged from bankruptcy on February 6, 1996 (the "Effective Date"). Pursuant to
the provisions of the Plan, on the Effective Date:

     (i)       The Company obtained $1.2 million in Debtor Notes financing which
     was fully subscribed on the Effective Date;

     (ii)      Unsecured Class 1 unsecured creditors were entitled to full
     payment equal to the amount of the allowed claim;

     (iii)     Secured Class 2 amount due CVD Financial was satisfied in the
     amount of $1,775,000 as follows: (a) a cash repayment of $625,000 on the
     Effective Date (b) the balance of $1,150,000, interest at 14% payable
     monthly, with principal payable quarterly at $82,142 over three and
     one-half years;

     (iv)      Unsecured Class 3 allowed claims due Unsecured Creditors were
     settled as follows: (a) $.10 cash for each dollar claim up to a maximum of
     $200,000 in total, (b) a pro rata share of 10,000 shares of common stock of
     the Reorganized Company, and (c) 50% of any net affirmative preference
     payment recoveries received from debtors.

     (v)       Unsecured Class 4 allowed claims due Unsecured Note Holders were
     settled through the issuance of 105,275 shares of common stock of the
     reorganized Company;

     (vi)      Unsecured Class 5 and 6 allowed claims of the two wholly-owned
     subsidiaries received $.80 for each claim dollar;

     (vii)     All preferred and common equity interests of the Company on the
     Effective Date were deemed cancelled, annulled and terminated, and any such
     holders of such interests received no distributions;

     (viii)    The Company retained full interest in the two wholly-owned
     subsidiaries.


                                                                           FS-12

1. REORGANIZATION AND BASIS OF REPORTING (Continued)

The financial statements as of and for the period ended February 29, 1996
reflect the Company's emergence from Chapter 11 and were prepared according to
the principles of fresh-start accounting contained in the provisions of American
Institute of Certified Public Accountants' Statement of Position 90-7,
"Financial Reporting by Entities in Reorganization Under the Bankruptcy Code"
("SOP 90-7"). As a result of the implementation of "fresh-start" accounting, the
Company's financial statements as of and for the period ended February 29, 1996
are not comparable to the Company's financial statements of prior periods.
Therefore, financial statements for the "Reorganized Company" have been
separately identified from those of the "Predecessor Company".

Reorganization value approximates fair value of the entity before considering
liabilities and approximates the amount a buyer would pay for the assets of the
Company after the reorganization.

The total reorganization value assigned to the Company's assets was based on the
$1.2 million debtor note financing which was converted to common stock which
represented 76.2% of the total common stock shares issued pursuant to the
Company's Plan of Reorganization. These convertible debtor notes have been used
as the basis for determining the net worth of the Company at the Effective Date.
The excess of the reorganization value over the value of the identifiable assets
is reported as "Reorganization Value in Excess of Amount Allocable to
Identifiable Assets" and is being amortized over twenty years. Under the
principles of "fresh-start" accounting, the Company's total assets were recorded
at this assumed reorganization value, with the reorganization value allocated to
identifiable tangible and intangible assets on the basis of their estimated fair
value. In addition, the Company's accumulated deficit was eliminated.


                                                                           FS-13

2. DISCONTINUED OPERATIONS

In November, 1993 the Company's Board of Directors authorized a change in the
focus of the business from whole blood to the plasma collection and distribution
business. Subsequent to determining that the Company would discontinue the whole
blood business the Company incurred various operating and other costs associated
with the discontinuance of the whole blood business. Costs amounting to $130,255
have been recognized for the year ended February 28, 1995 as a result of the
discontinued business line. These discontinued operation costs represent the
amount in excess of the estimated cost to discontinue that line of business
which was accrued at February 28, 1994.

3. INVENTORIES

Inventories at February 29, 1996 and February 28, 1995 consisted of the
following:

- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------

Softgoods supplies represent non-perishable supplies and instruments. Effective
January 1, 1996, the Company entered into new sales agreements with a customer
whereby the customer provides the softgoods supplies and the cost of such
supplies is factored into the unit sales prices as stated in the agreement.


                                                                          FS-16

5. LONG-TERM DEBT

In connection with the Restructuring, the Company entered into a New Term Loan
Agreement (the "New Loan Agreement") with CVD Financial on February 5, 1996. The
Company's New Loan Agreement replaced a Comprehensive Loan Facility and Security
Agreement dated October 1, 1993. At February 29, 1996 the Company's New Loan
Agreement provides for an outstanding balance in the face amount of $1,150,000
under a Consolidated Note. The unpaid principal balance of the Consolidated Note
will be paid in quarterly installments of $82,143 with the first principal
payment being due May 1, 1996 and the final principal payment due at maturity on
August 1, 1999. The Consolidated Note bears interest at 14% per annum.

The New Loan Agreement, which is secured by a pledge of substantially all assets
of the Company, requires the Company to comply with various covenants. The
carrying amount of the loan approximates its fair value.


                                                                           FS-17

6. CAPITAL STOCK

As discussed in Note 1, all preferred and common stock equity interests issued
prior to the Effective Date have been extinguished. The new authorized capital
stock of the company consists of 25,000,000 shares of Common Stock, par value
$.001 per share, and 25,000,000 shares of Preferred Stock, par value $.001 per

6. CAPITAL STOCK (Continued)

Current and previous management were issued 189,495 shares of common stock as of
the Effective Date of the Restructuring.

All common stock share certificates issued as a result of the aforementioned
transactions were formally issued in certificate form subsequent to February 29,
1996 (with the exception of the 10,000 common stock shares not yet issued to
Unsecured Creditors). The financial statements have been prepared on the basis
that all such shares are deemed issued on the Effective Date of the
Restructuring as a result of the extinguishment of all previously issued equity
interests. The total issued common stock shares is deemed to be 2,115,500 as of
February 29, 1996.

7. STOCK OPTIONS

The Company has entered into various employment and consulting agreements with
officers and directors of the company. As part of the agreements the officers
and directors were granted stock options as follows:

    The president and chief executive officer of the Company was granted the
    option to purchase 100,000 shares of common stock of the Company for the
    price of $1.00 per share, which was not below fair market value at that
    date. These options become fully vested upon execution of the agreement in
    February, 1996 and remain in effect until January, 2001.

    Additionally the president and chief executive officer was granted the
    following options, which, in addition to the vesting period (exercisable
    for a period of five years from the vesting date), vest only if the Company
    achieves certain projected operating results as defined in the agreement:

         (1) Option to purchase 56,147 shares of common stock of the Company at
         a mean price between $.74 and the weighted average, as defined in the
         agreement. The options vest one-third each year over a three year
         period beginning in January, 1997.

         (2) Option to purchase 50,000 shares of common stock of the Company
         for the price of $1.00 per share. These options become fully vested in
         January, 1997.

         (3) Option to purchase 50,000 shares of common stock of the Company
         for the price of $2.00 per share. These options become fully vested in
         January, 1998.

         (4) Option to purchase 50,000 shares of common stock of the Company

7. STOCK OPTIONS (Continued)

    The Vice President of Finance and Vice President of Operations were granted
    options to purchase 42,110 and 28,073 shares of common stock of the
    Company, respectively. The option purchase price is a mean price between
    $.74 and the weighted average, as defined in the agreement. The options
    vest one-third each year over a three year period beginning in January,
    1997 and vest only if the Company achieves certain projected operating
    results as defined in the agreement.

    In March, 1996 two directors were also granted options to purchase shares
    of common stock of the Company. One received options to purchase 30,000
    shares and the other received options to purchase 15,000 shares for the
    price of $1.50 per share. These options became fully vested at the granting
    date.

8.  LEASES

The Company is currently leasing its corporate office under a noncancelable
lease agreement. The corporate office lease agreement, which expires in April,
1999, replaced a previous corporate office lease which was replaced in May, 1996
as a result of the Company negotiating the terms of the current lease.

The Company is also obligated under various lease agreements for six donor
centers operated by the two wholly-owned subsidiaries. One donor center lease is
a month to month agreement. The remaining five leases expire at various dates
ranging from April, 1996 to December, 2002.

Future minimum rental obligations under the aforementioned lease agreements are
as follows:

    FEBRUARY 28,                                                     AMOUNT

     1998                                                            192,636

     2001                                                             61,582
     Thereafter                                                       42,210

9. INCOME TAXES

At February 29, 1996 the Company had a deferred tax asset in the amount of
$2,065,000 resulting primarily from net operating loss carryforwards. Due to
management's inability to conclude that it is more likely than not that the
deferred tax asset will be realized, a valuation allowance has been recorded for
the full amount.

At February 29, 1996, the Company estimates that approximately $5,900,000 of
Federal net operating loss carryforwards are available to potentially offset
future taxable income. These carryforwards will expire in various years
beginning in 2006 through 2011. As a result of the change in ownership
provisions of section 382 of the IRC, Federal tax rules will impose limitations
on the Company's ability to utilize its net operating loss carryforwards. Such
limitation will reduce the amount of these carryforwards that will be available
to offset future taxable income each year, starting with the year of
Restructuring. The dollar amount of these limitations is indeterminable at this
time.

If the Company's net operating loss carryforwards and other fresh start deferred
tax asset balances become realizable, the tax benefits will reduce
"Reorganization Value in Excess of Amount Allocable to Identifiable Assets". The
existing valuation allowance, if realized, would reduce this reorganization
value.

10. COMMITMENTS

The Company has entered into various employment and consulting agreements with
current and previous officers and directors of the Company. The following
further describes terms and obligations provided by the agreements entered into
by the Company with such officers and directors:

     The Company is obligated to the president and chief executive officer to
     pay an annual base salary of $75,000 for a three year period beginning in
     February, 1996.

     The Company is obligated to the vice president of finance to pay an annual
     salary of $125,000 for a three year period beginning in February, 1996. The
     salary is subject to quarterly adjustments with an annual increase of up to
     $10,000 in the event the Company achieves quarterly pre-tax earnings in
     excess of $100,000.


                                                                           FS-21

10. COMMITMENTS (Continued)

     The Company is obligated to the vice president of operations to pay an
     annual salary of $90,000 for a three year period beginning in February,
     1996. The salary is subject to quarterly adjustments with an annual
     increase of up to $10,000 in the event the Company achieves quarterly
     pre-tax earnings in excess of $100,000.

     The employment agreements also provide for a management bonus which will
     allocate on the basis of salaries, 10% of pre-tax earnings to management
     personnel in the event the Company achieves certain minimum annual pre-tax
     earnings, as defined in the agreements.

     The Company is obligated to a director of the Company to pay an annual
     consulting fee of $50,000 for a three year period beginning April, 1996.

The Company has entered into a termination agreement with the previous president
and chief executive officer. Under the terms of the agreement the Company is
obligated to pay the terminated officer $16,666 in two monthly installments of
$8,333 in February and March of 1996 and is obligated to pay $50,000 in twelve
installments of $4,167 beginning in February, 1996. This termination agreement
effectively cancels any previous employment agreements entered into between the
Company and the terminated officer.

11. CONCENTRATION OF CREDIT RISK, SIGNIFICANT CUSTOMERS AND SALES COMMITMENTS

The Company sells its only product, plasma, on credit primarily to fractionators
in the health care industry. The plasma provides specialty antibody products
that are used as the active ingredients in pharmaceutical products.

Plasma collection, storage, labeling and distribution activities are subject to
strict regulation and licensing by the U.S. Food and Drug Administration
("FDA"). The Company's facilities are subject to periodic inspection by the FDA.
Failure to comply or correct deficiencies with applicable laws or regulations
could subject the Company to enforcement action, including product seizures,
recalls, center or facility closure, license revocations and civil and criminal
penalties, any one or more could have a material adverse effect on the Company's
business.


                                                                           FS-22

- --------------------------------------------------------------------------------

11. CONCENTRATION OF CREDIT RISK, SIGNIFICANT CUSTOMERS AND SALES COMMITMENTS
(Continued)

Laws and regulations with similar substantive and enforcement provisions are
also in effect in many of the states and municipalities where the Company does
business. Any change in existing federal, state or municipal laws or
regulations, or in the interpretation or enforcement thereof, or the
promulgation of any additional laws or regulations could have an adverse effect
on the Company's business.

The Company is required to obtain from each donor an informed consent regarding
the donation procedure. Failure of the Company to obtain an adequate consent
could have a material adverse effect on the Company.

Three customers accounted for 100% of the net sales for the periods ended
February 28, 1995, February 5, 1996 and February 29, 1996.

The Company is currently obligated to one significant customer under the terms
of six agreements relating to the current six donor centers whereby the Company
has committed to sell substantially all of the plasma collected from those
centers at various unit prices as specified in those agreements. The agreements
expire at various dates through December 31, 1997 and may be terminated if the
donor centers fail to comply with various FDA, QPP and customer initiated
procedures.

12. SUBSEQUENT EVENTS

The Company has completed and issued a private placement memorandum dated June
1, 1996. The Company is offering $1,500,000 of security interests through the

to time the number of shares to be included in each such series, and to fix the
designation, powers, preferences and rights of the shares of each such series 
and qualifications, limitations or restrictions thereof.

       6.1 SPECIFIC AUTHORITY.  The authority of the Board with respect to 
each series shall include, but not be limited to, determination of the
following:

            (a) The number of shares constituting that series and the
distinctive designation of that series;

            (b) The dividend rate on the shares of that series, whether
dividends shall be cumulative, and, if so, from which date


                                       2

or dates, and the relative rights of priority, if any, of the payment of
dividends on shares of that series;

            (c) Whether that series shall have voting rights, in addition to
the voting rights provided by law, and, if so, the terms of such voting rights;

            (d) Whether that series shall have conversion privileges, 
and, if so, the terms and conditions of such conversion, including
provision for adjustment of the conversion rate in such events as the Board of
Directors shall determine;

            (e) Whether or not the shares of that series shall be 
redeemable, and, if so, the terms and conditions of such redemption,
including the date or date upon or after which they shall be redeemable, and the
amount per share payable in case of redemption, which amount may vary under
different conditions and at different redemption dates;

            (f) Whether that series shall have a sinking fund for the
redemption or purchase of shares of that series, and if so, the terms and amount
of such sinking fund; 

            (g) The rights of the shares of that series in the event of 
voluntary or involuntary liquidation, dissolution or winding up of
corporation, and the relative rights of priority, if any, of payment of shares
of that series;

            (h) Any other relative rights, preferences and limitations
of that series.

       6.2 DIVIDEND RIGHTS. Dividends on outstanding shares of Preferred
Stock shall be paid or declared and set apart for payment before any dividends
shall be paid or declared and set apart for payment on the shares of Common
Stock with respect to the same dividend period.

       6.3 LIQUIDATION RIGHTS.  If upon any voluntary or involuntary 
liquidation, dissolution or winding up of the Corporation, the assets
available for distribution to holders of shares of Preferred Stock of all series
shall be insufficient to pay such holders the full preferential amount to which
they are entitled, then such assets shall be distributed ratably among the
shares of all series of Preferred Stock in accordance with the respective 
preferential amounts (including unpaid cumulative dividends, if any) payable
with respect thereto.

     SEVENTH: In furtherance and not in limitation of the powers conferred by
statute and unless otherwise provided herein, the Board of Directors is, by 
action of the Board of Directors, expressly authorized to make, alter or
repeal the by-laws of the Corporation.

     EIGHTH:  Meetings of stockholders may be held within or outside of
the State of Delaware, as the by-laws of the Corporation may provide.  The books
of the Corporation may be kept outside the State of Delaware at such place or
places as may be designated from time to time by the Board of Directors of the
Corporation or in the by-laws of the Corporation.  Election of directors need
not be by written ballot unless the by-laws of the Corporation so provide.

     NINTH:  No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of his fiduciary
duty as a director; provided, however, that this provision shall not eliminate
or limit the liability of a director (1) for any breach of the director's duty
of loyalty to the Corporation or its stockholders, (2) for any acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (3) under Section 174 of the General Corporation Law of the State 
of Delaware, or (4) for any transaction from which the director derived an
improper personal benefit.

     TENTH:  The Corporation shall indemnify, in accordance with and to the 
full extent now or hereafter permitted by law, any person who was or is a 
party or is threatened to be made a party to any threatened, pending or 
completed action, suit or proceeding, whether  civil, criminal, 
administrative  or investigative (including, without limitation, an action 
by or in the right of the Corporation), by reason of his acting as a director 
or officer of the Corporation (and the Corporation, in the discretion of the 
Board of Directors, may so indemnify a person by reason of the fact that he 
is or was an employee of the Corporation or is or was serving at the request 
of the Corporation in any other capacity for or on behalf of the Corporation) 
against any liability or expense actually and reasonably incurred by such 
person in respect thereof. Such indemnification is not exclusive of any 
other right to indemnification provided by law or otherwise.  Expenses 
incurred by an officer or director in defending a civil or criminal action, 
suit or proceeding shall be paid by the Corporation in advance of the final 
disposition of such action, suit, or proceeding upon receipt of an 
undertaking by or on behalf of such officer or director to repay such amount 
if it shall ultimately be determined that such officer or director is not 
entitled to be indemnified. The right to indemnification and advancement of 
expenses on the condition specified herein conferred by this Article shall 
be deemed to be a contract between the Corporation and each person referred 
to herein.

     ELEVENTH: No amendment to or repeal of Article NINTH OR TENTH of this
Certificate of Incorporation shall apply to or have any effect on the rights of
any individual referred to in Article NINTH OR TENTH for or with respect 
to acts or omissions of such individual occurring prior to such amendment
or repeal.

                         American Blood Institute, Inc.
                             A Delaware Corporation

                                    ARTICLE I

                                     OFFICES

          Section 1.1  The corporation shall maintain a registered office in the
State of Delaware as required by law. The corporation may also have such other
offices, either within or without the State of Delaware, as the business of the
corporation may require.

                                   ARTICLE II

                                  STOCKHOLDERS

          Section 2.1  ANNUAL MEETING.  An annual meeting of the stockholders
shall be held commencing in 1992 on the first Monday of October of each year, if
not a legal holiday, and if a legal holiday, then on the next succeeding
business day, for the election of directors and for the transaction of such
other business as may come before the meeting.
          
          Section 2.2  SPECIAL MEETINGS.  Special meetings of the stockholders
may be called by the President, the board of directors, or by a request in
writing from the holders of not less than 51% of the issued and outstanding
voting stock of the corporation.  Within ten days after the receipt of such a
written request, the President or another officer designated by the President
must send a notice of meeting in accordance with section 2.4 hereof.
          
          Section 2.3  PLACE OF MEETING.  The board of directors may designate
any place, either within or without the State of Delaware, as the place of
meeting for any annual meeting or for any special meeting called by the board of
directors.  If a special meeting be called otherwise than by the board of
directors, the place of meeting must be in the county of Cook, State of
Illinois.
          
          Section 2.4  NOTICE OF MEETING.  Written notice stating the place,
date and hour of the meeting, the place where the stockholder list may be
examined prior to the meeting, if different from the place of the meeting, and,
in


<PAGE>

the case of a special meeting, the purpose or purposes for which the meeting is
called, shall be given in person or sent by mail or overnight express service
not less than ten nor more than sixty days before the date of the meeting, or in
the case of a merger or consolidation of the corporation requiring stockholder
approval or a sale, lease or exchange of all or substantially all of the
corporation's assets, not less than twenty nor more than sixty days before the
date of meeting, to each stockholder of record entitled to vote at such meeting.
If mailed, notice shall be deemed given when deposited in the United States
mail, postage prepaid, directed to the stockholder at his address as it appears
on the records of the corporation.  If notice is given by overnight express
service, such notice shall be deemed given one day after delivery to such
express service.  When a meeting is adjourned to another time or place, notice
need not be given of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken, unless the
adjournment is for more than thirty days, or unless, after adjournment, a new
record date is fixed for the adjourned meeting, in either of which cases notice
of the adjourned meeting shall be given to each stockholder of record entitled
to vote at the meeting.  Notice need not be given to any stockholder who submits
a written waiver of notice signed by such stockholder either before or after any
meeting. Attendance by a stockholder at a meeting of stockholders shall
constitute a waiver of notice of such meeting, except when the stockholder
attends the meeting for the express purpose of objecting, at the beginning of
the meeting, to the transaction of any business because the meeting is not
lawfully called or convened.  Neither the business to be transacted at, nor the
purpose of, any regular or special meeting need be specified in any waiver of
notice of such meeting.

         Section 2.5  FIXING OF RECORD DATE.  (a) In order that the corporation
may determine the stockholders entitled to notice of or to vote at any meeting
of stockholders or any adjournment thereof, the board of directors may fix a
record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the board of directors, and
which record date shall not be more than sixty nor less than ten days before the
date of such meeting. If no record date is fixed by the board of directors, the
record date for determining stockholders entitled to notice of or to vote at a
meeting of stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held.  A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any


                                        2
<PAGE>

adjournment of the meeting; provided, however, that the board of directors may
fix a new record date for the adjourned meeting.

         (b)  In order that the corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the board
of directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the board of
directors, and which date shall not be more than ten days after the date upon
which the resolution fixing the record date is adopted by the board of
directors.  If no record date has been fixed by the board of directors, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting, when no prior action by the board of directors is
required by the Delaware General Corporation Law, shall be the first date on
which a signed written consent setting forth the action taken or proposed to be
taken is delivered to the corporation by delivery to its registered office in
Delaware, its principal place of business, or an officer or agent of the
corporation having custody of the book in which proceedings of meetings of
stockholders are recorded.  Delivery made to the corporation's registered office
shall be by hand or by certified or registered mail, return receipt requested. 
If no record date has been fixed by the board of directors and prior action by
the board of directors is required by the Delaware General Corporation Law, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting shall be at the close of business on the day on
which the board of directors adopts the resolution taking such prior action.

         (c)  In order that the corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the board of directors may fix a record date, which record date
shall not precede the date upon which the resolution fixing the record date is
adopted, and which record date shall be not more than sixty days prior to such
action.  If no record date is fixed, the record date for determining
stockholders for any such purpose shall be at the close of business on the day
on which the board of directors adopts the resolution relating thereto.

         Section 2.6  VOTING LISTS.  The officer who has charge of the stock
ledger of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the



                                        3
<PAGE>

meeting, arranged in alphabetical order, and showing the address of each
stockholder and number of shares registered in his name, which list, for a
period of ten days prior to such meeting, shall be kept on file either at a
place within the city where the meeting is to be held and which place shall be
specified in the notice of the meeting, or, if not so specified, at the place
where the meeting is to be held, and shall be open to the examination of any
stockholder, for any purpose germane to the meeting, at any time during ordinary
business hours.  Such list shall also be produced and kept at the time and place
of the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

         Section 2.7  STOCK LEDGER.  The stock ledger shall be the only evidence
as to who are the stockholders entitled to examine the stock ledger or the books
of the corporation, or to vote in person or by proxy at any meeting of
stockholders.
         
         Section 2.8  QUORUM.  A majority of the outstanding shares of voting
stock of the corporation, represented in person or by proxy, shall constitute a
quorum at any meeting of stockholders; provided, however, that if less than a
majority of the outstanding shares of voting stock are represented at said
meeting, a majority of the shares of voting stock so represented may adjourn the
meeting.  If a quorum is present, the affirmative vote of a majority of the
shares of voting stock represented at the meeting shall be the act of the
stockholders in all matters other than the election of directors, who shall be
elected by a plurality of the votes of the shares present in person or by proxy
and entitled to vote on the election of directors, unless the vote of a greater
number or voting by classes is required by the Delaware General Corporation Law,
the certificate of incorporation or these by-laws. At any adjourned meeting at
which a quorum shall be present, any business may be transacted which might have
been transacted at the original meeting.  Requirements of notice at any
adjourned meeting are governed by Section 2.4 hereof. Withdrawal of stockholders
from any meeting shall not cause failure of a duly constituted quorum at that
meeting.

         Section 2.9  PROXIES.  Each stockholder entitled to vote at a meeting
of stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from its
date, unless the proxy provides for a longer period.  Every proxy must be signed
by the stockholder or his attorney-in-fact.  A duly executed proxy shall be
irrevocable if it states that it is irrevocable, and if, and only as long as, it
is coupled with an interest sufficient in law to support


                                        4
<PAGE>

an irrevocable power.  A proxy may be made irrevocable regardless of whether the
interest with which it is coupled is an interest in the stock itself or an
interest in the corporation generally.

         Section 2.10  VOTING OF STOCK.  Subject to the provisions of the
certificate of incorporation, each stockholder shall at every meeting of the
stockholders be entitled to one vote for each share of the voting stock held by
such stockholder.
         
         Section 2.11  VOTING OF STOCK BY CERTAIN HOLDERS. Persons holding stock
in a fiduciary capacity shall be entitled to vote the shares so held.  Persons
whose stock is pledged shall be entitled to vote, unless in the transfer by the
pledgor on the books of the corporation he has expressly empowered the pledgee
to vote thereon, in which case only the pledgee or his proxy may represent such
stock and vote thereon.  Shares of its own stock belonging to the corporation or
to another corporation, if a majority of the shares entitled to vote in the
election of directors of such other corporation is held, directly or indirectly,
by the corporation, shall neither be entitled to vote nor counted for quorum
purposes, but shares of its stock held by the corporation in a fiduciary
capacity may be voted by it and counted for quorum purposes.
         
         Section 2.12  CONSENT OF STOCKHOLDERS.  (a) Unless otherwise provided
in the certificate of incorporation, any action required to be taken at any
annual or special meeting of stockholders of the corporation, or any action
which may be taken at any annual or special meeting of stockholders, may be
taken without a meeting, without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted and shall be delivered to the
corporation by delivery to its principal place of business, or to an officer or
agent of the corporation having custody of the book in which proceedings of
meetings of stockholders are recorded.  Delivery made to the corporation's
registered office in Delaware shall be by hand or by certified or registered
mail, return receipt requested.

         (b) Every written consent shall bear the date of signature of each
stockholder who signs the consent and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty days of the
earliest dated consent delivered in the manner required by this section to the
corporation, written consents signed by a sufficient


                                        5

number of holders to take such action are delivered to the corporation by

         Section 2.14  INSPECTORS.  The board of directors, in advance of any
meeting, may, but need not, appoint one or more inspectors of election to act at

stockholder shall, appoint one or more inspectors.  In case any person who may
be appointed as an inspector fails to appear or act, the vacancy may be filled
by appointment made by the directors in advance of the meeting or at the meeting
by the person presiding thereat.  Each inspector, if any, before entering upon
the discharge of his duties, shall take and sign an oath faithfully to execute
the duties of inspector at such meeting with strict impartiality and according

of shares of stock outstanding and the voting power of each, the shares of stock
represented at the meeting, the existence of a quorum, the validity and effect
of proxies, and shall receive votes, ballots or consents, hear and determine all
challenges and questions arising in connection with the right to vote, count and

determined by him or them and execute a certificate of any fact found by him or
them.

         Section 3.1  GENERAL POWERS.  The business of the corporation shall be
managed by or under the direction of its board of directors, except as otherwise
provided in the certificate of incorporation.
         
         Section 3.2  NUMBER AND QUALIFICATIONS.  The number of directors of the
corporation shall be one (1) or such other number as may be determined from time
to time by the board of directors of the corporation at a duly held meeting
thereof. Directors need not be stockholders of the corporation, citizens of the
United States or residents of the State of Delaware.
         
         Section 3.3  ELECTION AND TERM.  The board of directors shall be
elected at the annual meeting of the stockholders of the corporation and shall
hold office until their successors are elected and qualified or until their
earlier death, resignation or removal.  Any director may resign at any time upon
written notice to the corporation.  Thereafter, directors who are elected at an
annual meeting of stockholders, and directors who are elected in the interim to
fill vacancies and newly created directorships, shall hold office until the next
annual meeting of stockholders and until their successors are elected and
qualified or until their earlier death, resignation or removal.  In the interim
between annual meetings of stockholders or of special meetings of stockholders
called for the election of directors and/or for the removal of one or more
directors and for the filling of any vacancy in that connection, newly created
directorships and any vacancies in the board of directors, including vacancies
resulting from the removal of directors, may be filled by the vote of a majority
of the remaining directors then in office, although less than a quorum, or by
the sole remaining director.
         
         Section 3.4  REGULAR MEETINGS.  A regular meeting of the board of
directors shall be held without other notice than this by-law, immediately
after, and at the same place as, the annual meeting of stockholders.  Meetings

         Section 3.6  NOTICE.  Notice of any special meeting stating the time
and place of such meeting shall be given at least three days previous thereto by
written notice delivered personally or sent by mail or overnight express service
to each director at his business address.  Such notice shall be deemed to be
delivered when deposited in the United States mail or given to such overnight
express service so addressed, with postage thereon prepaid.  Notice need not be
given to any director who submits a written waiver of notice signed by him
either before or after any meeting.  The attendance of a director at any meeting
shall constitute a waiver of notice of such meeting, except where a director
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened.  Neither the business to be transacted at, nor the purpose
of, any regular or special meeting of the board of directors need be specified
in the notice or waiver of such meeting.
         
         Section 3.7  QUORUM.  A majority of the number of directors fixed by or
determined in accordance with these by-laws (or of the members of any committee
in the case of a meeting of a committee of the board of directors) shall
constitute a quorum for the transaction of business at any meeting of the board
of directors or of such committee, provided, however, that if less than a
majority of such number of directors are present at said meeting, a majority of
the directors present may adjourn the meeting from time to time without further
notice.  Interested directors may be counted in determining the presence of a
quorum at a meeting of the board of directors or of a committee thereof.
         
         Section 3.8  MANNER OF ACTING.  The vote of a majority of the directors
present at a meeting at which a quorum is present shall be the act of the board
of directors or of a committee of the board, as the case may be.
         
         Section 3.9  ACTION WITHOUT A MEETING.  Any action required or
permitted to be taken at any meeting of the board of directors or of any
committee thereof may be taken without a meeting if all the members of the board
or committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the board or committee.
         
         Section 3.10  COMPENSATION,  The board of directors shall have
authority to establish reasonable compensation of all


                                        8

directors for services to the corporation as directors, officers or otherwise.

         Section 3.11  LIABILITY FOR UNLAWFUL PAYMENT OF DIVIDEND.  In case of
any willful or negligent violation of the provisions of sections 160 or 173 of
the Delaware General Corporation Law regarding the payment of dividends, any
director who may have been absent when the same was done, or who may have
dissented from the act or resolution by which the same was done, may exonerate
himself from such liability by causing his dissent to be entered on the books
containing the minutes of the proceedings of the directors at the time the same
was done, or immediately after he has notice of the same.
         
         Section 3.12  TELEPHONE MEETINGS.  Members of the board of directors or
of any committee thereof may participate in a meeting of the board by means of a
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and such participation
shall constitute presence in person at the meeting.
         
         Section 3.13  REMOVAL.  Any director or the entire board of directors
may be removed with or without cause by the holders of a majority of the shares
then entitled to vote at an election of directors.
         
         Section 3.14  COMMITTEES.  The board of directors may, by resolution
passed by a majority of the whole board, designate one or more committees, each
committee to consist of one or more of the directors of the corporation.  Any
such committee, to the extent provided in the resolution of the board of
directors, shall have and may exercise all the powers and authority of the board
of directors in the management of the business and affairs of the corporation,
to the extent permitted under the Delaware General Corporation Law.

directors held after each annual meeting of stockholders.  If the election of
officers shall not be held at such meeting, such election shall be held as soon
thereafter as convenient. New offices may be created and filled at any meeting
of the board of directors.  Each officer shall hold office until his successor
is elected and has qualified or until his earlier death, resignation or removal.
Any officer may resign at any time upon written notice to the corporation. 
Election of an officer shall not of itself create contract rights.

         Section 4.3  REMOVAL.  Any officer elected by the board of directors
may be removed by the board of directors whenever in its judgment the best
interests of the corporation would be served thereby, but such removal shall be
without prejudice to the contract rights, if any, of the person so removed.

         Section 4.4  VACANCIES.  A vacancy in any office occurring because of

transfer agent or registrar who has signed or whose facsimile signature has been
placed upon such certificate shall have ceased to be such officer, transfer
agent or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he were such officer, transfer agent or

represented thereby are issued, with the number of shares and date of issue,
shall be entered on the books of the corporation.  All certificates surrendered
to the corporation for transfer shall be cancelled and no new certificates shall
be issued until the former certificate for a like number of shares shall have
been surrendered and cancelled, except that in case of a lost, destroyed or
mutilated certificate, a new certificate may be issued therefor upon such terms,
indemnity and surety to the corporation as the board of directors may prescribe.

         Section 6.2  TRANSFER OF SHARES OF STOCK.  Transfers of shares of stock
of the corporation shall be made on the books of the corporation by the holder

corporation.

                                   ARTICLE VII

                                 INDEMNIFICATION

         Section 7.1  DIRECTORS AND OFFICERS.  (a)  The corporation shall
indemnify any person who was or is a party or is threatened to be made party to
any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director or
officer of the corporation, or is or was serving at the request of the
corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.  The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of NOLO CONTENDERE or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.
         
         (b)  The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor by reason of the fact that he is or was a director or officer of the
corporation, or is or was serving at the request of the


                                       13

<PAGE>

corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery of the State of Delaware or the court in which action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery of the State of Delaware or such other court shall deem proper.

          (c)  To the extent that any person referred to in paragraphs (a) and
(b) of this Section 7.1 has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to therein or in defense of
any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

          (d)  Any indemnification under paragraphs (a) and (b) of this section
7.1 (unless ordered by a court) shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification of the
director or officer is proper in the circumstances because he has met the
applicable standard of conduct set forth in paragraphs (a) and (b) of this
section 7.1.  Such determination shall be made (i) by the board of directors by
a majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding or (ii) if such quorum is not obtainable, or, even if
obtainable a quorum of disinterested directors so directs, by independent legal 
counsel in a written opinion, or (iii) by the stockholders.

         (e)  Expenses incurred in defending a civil or criminal action, suit or
proceeding may be paid by the corporation in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of the director or officer to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation as
provided in this section 7.1.

          (f)  The indemnification and advancement of expenses provided by or
granted pursuant to this section 7.1 shall not


                                       14

<PAGE>

be deemed exclusive of any other rights to which those seeking indemnification
or advancement of expenses may be entitled under any statute, by-law, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action
in his official capacity and as to action in another capacity while holding such
office.

         (g)  The corporation shall have power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under the provisions of this section 7.1.

         (h)  For purposes of this section 7.1, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the corporation"
shall include any service as a director, officer, employee or agent of the
corporation which imposes duties on, or involves services by, such director,
officer, employee, or agent with respect to an employee benefit plan, its
participants or beneficiaries; and a person who acted in good faith and in a
manner he reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the corporation" as referred to in
this section.

         (i)  The indemnification and advancement of expenses provided by, or
granted pursuant to, this section shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

         (j)  Unless otherwise determined by the board of directors, references
in this section to "the corporation" shall not include in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or


                                       15

<PAGE>

is or was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under this section
with respect to the resulting or surviving corporation as he would have with
respect to such constituent corporation if its separate existence had continued.

         Section 7.2  EMPLOYEES AND AGENTS.  The board of directors may, by
resolution, extend the indemnification provisions of the foregoing section 7.1
to any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding by reason of the
fact that he is or was an employee or agent of the corporation, or is or was
serving at the request of the corporation as an employee or agent of another
corporation, partnership, joint venture, trust or other enterprise.

                                SERACARE, INC.

                    -----------------------------------------

                    Pursuant to Section 151(g) of the General
                    Corporation Law of the State of Delaware

                    -----------------------------------------

          I, the undersigned, Barry D. Plost, being the President of SeraCare,
Inc., a Delaware corporation (the "Corporation"), hereby certify pursuant to
Section 151(g) of the General Corporation Law of the State of Delaware that:

          1.   The name of the Corporation is SeraCare, Inc.

          2.   The Certificate of Incorporation of the Corporation was filed
with the Secretary of State on October 1, 1991.

          3.   Pursuant to authority thereby vested in the Board of Directors 
by Article Sixth of the Corporation's Restated Certificate of Incorporation, 
the Board of Directors adopted the following resolutions on July 9, 1996 
establishing a series of up to 3,600 shares of Preferred Stock of the 
Corporation to be known as Series A Preferred Stock:

          "RESOLVED, that pursuant to Section 151(g) of the General 
Corporation Law of the State of Delaware and Article Sixth of the 
Corporation's Restated Certificate of Incorporation, there is hereby 
established a series of the Corporation's Preferred Stock having the 
following terms and designations:

          (i)  The distinctive serial designation of this series shall be 
"Series A Preferred Stock" (hereinafter called "Series A").  Each share of 
Series A shall be identical in all respects with the other shares of Series A.

          (ii) The number of shares in Series A shall initially be 3,600 which
number may from time to time be increased or decreased (but not below the number
then outstanding) by the Board of Directors.  Shares of Series A redeemed or
purchased by the Corporation shall be canceled and shall revert to authorized
but unissued Preferred Stock undesignated as to series.

          (iii) The holders of the Series A shall be entitled to receive
dividends, payable monthly, at the rate of eight percent (8%) of the Redemption
Price (as defined below) per share per annum, payable in preference to all other
shareholders.  Such dividends shall be cumulative, and no dividend shall be paid
on the shares of any other class unless the current dividend, and

<PAGE>

all arrears of dividends, if any, on the shares of the Series A shall have been
paid, or provision shall have been made for the payment thereof.  The holders of
shares of Series A shall at no time have any other right to further dividends of
any kind.

           (iv)  Subject to adjustment as set forth below, the Corporation shall
redeem the outstanding shares of the Series A at a price per share (the
"Redemption Price") equal to (a) Five Hundred Fifty Thousand and No/100
($550,000), less an amount which equals the difference between the cash, bank
accounts (to the extent that checks or drafts have not been written) and
accounts receivable (the "Assigned Assets") delivered or assigned under the
Contract for Exchange of Corporate Stock (the "Agreement"), dated July 9, 1996
(the "Assumed Indebtedness"), DIVIDED BY (b) 3,600, and rounded up to the next
$0.01.  The Corporation shall redeem 100 shares per month (in pro rata portions
from each holder of Series A according to the respective number of shares of
Series A held by such holder), beginning on the closing date under the
Agreement.  On or promptly following any redemption date, each holder of shares
of Series A redeemed shall surrender the certificate evidencing such shares to
the Corporation.  If after the closing under the Agreement, the assignee fails
to pay an Assumed Indebtedness or the Corporation learns of any indebtedness or
other liability which was not disclosed prior to the closing, the Redemption
Price shall be reduced by an amount equal to (x) the amount of money the
Corporation is required to pay to satisfy said assumed indebtedness or
undisclosed liability, DIVIDED BY (y) 3,600, and rounded up to the next $0.01. 
In such event, a new amortization schedule shall be prepared and the balance of
the aggregate Redemption Price as reduced shall be paid upon redemption of the
remaining outstanding Series A shares.

           (v)  Except as required by law, the holders of the Series A shall not
be entitled to vote on matters presented to the holders of the junior stock or
of any other Series or class of Preferred Stock which is entitled to vote by its
designations.

           (vi) The shares of the Series A shall not have any relative,
participating, optional or other special rights and powers other than as set
forth herein."

                              EMPLOYMENT AGREEMENT

           This EMPLOYMENT AGREEMENT ("Agreement") dated February 5, 1996, is
entered into by and between American Blood Institute, Inc., a Delaware
corporation, AKA SeraCare (the "Company") and Barry Plost (the "Employee").
           
          l. EMPLOYMENT AND EFFECTIVENESS.  The Company hereby employs the
Employee, and the Employee accepts employment, as of the date first set forth
above (the "Commencement Date"), under the terms and conditions of this
Agreement.
 
           2.  TERM.  The employment of the Employee pursuant to this Agreement
shall begin as of the Commencement Date and shall continue to and through the
date which is the third anniversary of the Commencement Date (the "Employment
Term"), unless terminated earlier as provided herein.
           
           3.  POSITION AND DUTIES.  The Employee shall be employed as Chairman
of the Board, President, and Chief Executive Officer and shall have the duties,
responsibilities and authority as may from time to time be assigned by the
Company's Board of Directors that are consistent with and normally associated
with such positions. The Employee shall devote sufficient amounts of his
business time, effort and energies exclusively to the business of the Company to
fulfill the duties of his office.  Employee shall not be employed by or act in
any capacity on behalf of any company which competes with the Company's plasma
collection business and shall not serve as an active principal or director or
officer or employee of any other company or entity without the prior written
consent of the Board of Directors, except that the Employee may serve as a
director or officer of any trade association, civic, educational or charitable
organization without such consent.  The Employee shall also serve without
additional compensation as an officer and director of the Company and any of its
subsidiaries, if so elected or appointed, but if not so elected or appointed the
compensation hereunder shall in no way be affected.  The Employee shall devote
his or her best efforts to advancing the interests of the Company.
           
          4.  COMPENSATION AND BENEFITS.

     (a)  During the Employment Term, the Company shall pay the Employee a 
base salary at the annual rate of seventy-five thousand dollars ($75,000) (the 
"Base Salary"), payable in accordance with the normal payroll practices 
established by the Company.  The Employee shall be entitled to such increases 
in the Base Salary as may be determined from time to time by the Company's 
Board of Directors or pursuant to its delegation.  If the Base Salary is 
increased during the

                                        1

<PAGE>

Employment Term, the new salary shall thereafter constitute the "Base Salary"
for purposes of this Agreement.

     (b)  In addition to Base Salary, the Employee shall be entitled to the
following stock option grants:

           (i)  Options to purchase 56,147 shares of common stock of the Company
for a calculated price which is the mean average between $.74 and the weighted
average of the closing bid price for the Company's common stock for the thirty
trading days prior to the vesting date.  The vesting date shall be an
anniversary date of January 24 and, contingent upon the Company achieving the
performance criteria set forth in section (v) below, the options will vest one-
third each year beginning on January 24, 1997 and shall remain excercisable by
Employee for a period of five (5) years from the vesting date.

           (ii)  Options to purchase 50,000 shares of common stock of the
Company for the price of $1.00 per share which shall vest on the one year
anniversary of the date of this Agreement in 1997, contingent upon the Company
achieving the performance criteria set forth in section (v) below, and shall
remain excercisable by Employee for a period of five (5) years from the vesting
date.

           (iii)  Options to purchase 50,000 shares of common stock of the
Company for the price of $2.00 per share which shall vest on the second year
anniversary of the date of this Agreement in 1998, contingent upon the Company
achieving the performance criteria set forth in section (v) below, and shall
remain excercisable by Employee for a period of five (5) years from the vesting
date.

           (iv)  Options to purchase 50,000 shares of common stock of the
Company for the price of $3.00 per share which shall vest on the third year
anniversary of the date of this Agreement in 1999, contingent upon the Company
achieving the performance criteria set forth in section (v) below, and shall
remain excercisable by Employee for a period of five (5) years from the vesting
date.

           (v)  The options granted in sections (i), (ii), (iii), and (iv) above
shall vest only if Employee is an employee of the Company on the date the
options are to vest and then only if the Company has achieved the projected
operating results as reflected in the Five Year Post Emergence Forecast, a copy
of which is attached hereto. However, if the Company fails to obtain the outside
funding for the acquisition centers in a timely fashion, then the calculation of
the performance criteria will be made utilizing the projected results of the
base six centers for the year (which includes corporate overhead) plus a pro-
rata calculation of the projected operating results of the  


                                        2

<PAGE>

acquisition centers for the year based upon the percentage of the outside
secondary financing actually received by the Company compared to the projected
financing.  For example, if the projections contemplate the acquisition of 12
centers during year one utilizing outside financing of $2,400,000 ($200,000 per
center) and only $1,200,000 or 504 is actually funded, then the performance
target for the option vesting will equal 100% of the projected operating results
from the six centers ($365,556), plus 50% of the one year projected operating
results of the projected acquisition centers ($50% x $450,198 = $225,099), or a
total of $590,655.  If any of the options do not vest on the vesting date, such
option rights shall terminate immediately and be of no further effect.

           (vi)  Options to purchase 100,000 shares of common stock in the
Company for the price of $1.00 per share, such options to vest upon the
execution of this Agreement and remain in effect for a period of 5 years from
such date.
 
           (vii)  If the Company is sold, merged into, or consolidated with
another entity, or the Company is substantially reorganized by a 50% or more
change in ownership (exclusive of the conversion of Debtors Notes), and either
Employee s position, duties, or compensation is reduced, then all options
granted under this Agreement shall become immediately vested and exercisable.
 
     (c)  The Employee shall be eligible to participate in other employee
benefit plans maintained by the Company during the Employment Term, and to
receive all fringe benefits, for which his or her status and level of employment
qualify in accordance with the Company's usual policies and arrangements and the
terms of such plans, policies and arrangements.  Such benefits and plans may
include vacation pay, medical insurance programs and retirement programs.

     (d)  The Company will pay to or on behalf of Employee, the costs, up to a
maximum of $10,000 per year, of Employee's Blue Cross/ Blue Shield medical
insurance coverage and a term life insurance policy in the face amount of
$500,000.

            5.  TERMINATION.  This Agreement shall terminate upon the earlier of
the following:
            
     (a)  The date provided under the provisions of Section 2 hereof.

     (b)  Upon the determination by the Board of Directors that good cause
exists to justify the termination of the Employee for gross misconduct.  For
purposes of this Agreement, "gross misconduct" shall be defined as theft,


                                        3

<PAGE>

dishonesty, alcohol or drug abuse, unethical business conduct, gross negligence,
commission of an illegal act detrimental to the Company or its reputation,
fraud, or a material breach of this Agreement by Employee.  Upon any termination
under this subsection (b) Employee shall be paid an amount equal to thirty days
of his base salary, and no other compensation or benefits other than the receipt
of his vested options.

     (c)  At the Company's option, upon the occurrence of a physical or mental
condition which prevents the Employee from performing the duties for which he or
she is responsible for a period of 120 consecutive days or 180 days in total
during the term of this Agreement,

     (d)  Upon the determination by the Board of Directors that Employee has
engaged in acts detrimental to the Company, including without limitation
insubordination, failure to comply with instructions, and actions or
associations which materially and adversely affect the Company's reputation,
business, stock price, or ability to raise capital, and Employee has failed to
cease or correct such actions within ten (10) days of his receipt of written
notice from the Board of Directors.  In the event of a termination under this
subsection (d) Employee shall be entitled to severance pay equal to his base
salary amount for the lesser of twelve months or the remaining term of this
Agreement and his vested options, and no other compensation or benefits.

     (e)  Upon Employee's death, voluntarily ceasing to perform his duties,
other than by reason of a disability under subsection (d), or agreement to
terminate this Agreement.

Except as specified above, all rights to compensation and options which have not
vested under this Agreement shall cease upon the termination of this Agreement.

          6. COVENANTS.

          (a) The Employee shall not, during the term of the employment or at
any time thereafter, directly or indirectly, publish or disclose to any person,
firm, corporation or other entity, whether or not a competitor of the Company,
or use other than on behalf of the Company any confidential information
concerning the assets, business or affairs of the Company unless required by a
court of law or governing governmental authority pursuant to a specific right to
know.  Confidential information includes, without limitation, any trade secrets,
sources of supply, costs, pricing practices, customer lists, financial data,
employee information, strategic plans, or organizational data.

          (b)  The Employee shall not during the Employment Term and for a
period of two (2) years thereafter, engage in or be interested in (as owner,
partner, shareholder, employee, director, officer, agent, consultant or
otherwise, except as a less than 1% shareholder of a publicly listed company)
with or without compensation, any business which is competitive with the
business being conducted by the Company at any time during the Employee's
employment, including any business which owns or operates a blood collection
center within 50 miles of any of the Company's collection centers. The Employee

any employee of the Company, with the view to induce or encourage such employee
to leave the employ of the Company for the purpose of being hired by the
Employee, an employer affiliated with the Employee or any competitor of the
Company.

          (c)  Employee agrees that all files, records, documents and items

are reasonable and necessary for the protection of the Company and that the
Company will be irrevocable damaged if such covenants are not specifically
enforced.  Accordingly, the Employee agrees that, in addition to any other
relief or remedies available to the Company in the form of actual or punitive
damages, the Company shall be entitled to seek and obtain injunctive relief from
a court of competent jurisdiction for the purposes of restraining the Employee
from any actual or threatened breach of such covenants.

           7.  INDEMNIFICATION.  The Company shall indemnify, defend and hold
the Employee harmless, to the maximum extent permitted by law, from any and all
claims, litigation or suits arising out of the activities of the Employee
reasonable taken in the performance of the duties hereunder, including all
reasonable expenses and professional fees that may relate thereto.  In addition,
the Company agrees to seek appropriate directors and officers liability
insurance for errors and omissions of such type and in such amount as is

           8.  ARBITRATION.  Any controversy or dispute between the Company and

Employee's employment other than pursuant to the provisions of Section 5 of this
Agreement, the Employee's complete and exclusive remedy shall be the payment in
cash, within 30 days of the termination, of the unpaid balance of the full
compensation which would be due under the full term of this Agreement, including
base salary and options, and the continuation of Employee's then current medical
and insurance benefits for a period of twelve months from the date of the
termination.

                           EMPLOYMENT AGREEMENT

          THIS EMPLOYMENT  AGREEMENT ("Agreement")  is intended  to be the
operative agreement by and between American Blood Institute, Inc., AVRE, Inc.,
and Binary  Associates, Inc.   AKA SeraCare  (referred to collectively  herein
as  the  "Corporation")  and  Jerry  L.  Burdick ("Burdick").   This Agreement
is conditional  upon confirmation  of a Plan of Reorganization  for the
Corporation and approval  of such Plan of Reorganization by the Federal
Bankruptcy Court.  The effective date of  this  Agreement  shall  be  the
Effective  Date  of  the  Plan  of Reorganization.

          l.    EMPLOYMENT  AS   VICE  PRESIDENT   OF  FINANCE.    The
Corporation hereby agrees to retain  Burdick and Burdick hereby agrees to be
employed as Vice President  of Finance for the Plasma Operations to  be acquired
by the  Corporation  via the  Plan of  Reorganization regarding  American  Blood
Institute,  Inc., AVRE,  Inc.  and  Binary Associates, Inc.  In such capacities,
Burdick shall perform all of the normal duties and responsibilities of a Vice
President of Finance.  In the performance of  his duties and responsibilities,
Burdick shall at all times  be under the  direction of the  President and the

responsibilities in accordance with  all reasonable rules, regulations and
policies adopted by the Board of Directors of the Corporation.

          2.   INDEMNIFICATION ; INSURANCE AGREEMENT  The Corporation warrants
and assures  Burdick  that the  Charter  of the  Corporation contains a
provision which provides for indemnification of officers by the corporation  to
the maximum  extent permissible under the  laws of the jurisdiction  in which
the Corporation  is incorporated.  Further, the Corporation agrees  to either or
both of the  following: (A) Enter into an  Indemnification Agreement provided
that  such Indemnification Agreement shall be  modified if necessary to conform
with  the laws of the jurisdiction in which the  Corporation is incorporated;
(B) Obtain and maintain in  full force and effect at  Corporation's sole
expense, such  director's  and officer's  liability  insurance  for errors  and
omissions  of  such type  and  in  such  amount  as is  customary  for similarly
situated companies, if available at reasonable cost.

          3.  EXTENT OF SERVICES.  Burdick agrees to devote all of his time  and
efforts on  behalf  of  the  business of  the  Corporation. Without limiting
the foregoing,  during the  term of  this Agreement, Burdick shall make written
request to  the Board of Directors and must obtain written  approval from such
Board if Burdick wishes  to devote any of  his time  to any  other business
effort,  whether or  not such business effort is in direct competition with the
Corporation.

          4.  COMPENSATION.   On the effective date  of this contract, Burdick
shall be  paid  at  the rate  of  $125,000  per year  payable bi-weekly.  There
shall  be a quarterly salary  adjustment whereby any pre-tax  earnings over
$100,000  per  quarter shall  be  paid to  the officers of the  Reorganized
Debtor (SeraCare) up to  a maximum annual amount of $25,000  to Alfred J. Moran,
Jr. and  $10,000 each for Jerry L.  Burdick  and  Brian  Olson.  The
distribution  of  the  quarterly salary adjustment shall be on a pro rata basis.

<PAGE>

          5.   PERFORMANCE BONUS.   There shall  also be  a Management Bonus
Pool which  will allocate ten percent (10%)  of pre-tax earnings which are  in
excess of $920,549  in year one following  the Effective Date of the
Reorganization Plan, $2,590,160 in year two, $4,384,187 in year three,
$6,244,536 in year four,  and $8,166,626 in year five to a bonus pool to be paid
pro rata to management on the basis of salaries. Burdick shall  be a participant
in this Management Bonus  Pool during the term of this agreement.

          6.  FRINGE  BENEFITS.  Burdick shall receive  four (4) weeks paid
vacation per  year during the course of  this Agreement.  Burdick will  also
receive  company paid:  sick pay,  group health  insurance, dental  care, vision
care, disability  insurance, life  insurance and such  other benefits  in the
amounts and  as may  be provided  in the ordinary course to the Corporation's
other senior executives.

          7.   STOCK  AND WARRANT  GRANT.   Burdock  shall be  granted 63,165
shares of common stock  of SeraCare (SeraCare is herein defined as AVRE, Inc.,
Binary Associates, Inc., American Blood Institute, Inc. and any post emergence
replacement  or successor corporation or entity into which the Plasma Operations
of Avre, Inc. and Binary Associates, Inc. are transferred, placed, controlled,
merged or which are acquired by) and  stock options to  purchase 42,110  shares
of common  stock in SeraCare for a calculated price which is the mean average
between $.74 and the  weighted average of the  closing bid price for  the
Company's stock for  the thirty  trading days  prior to  the vesting  date.  The
vesting date is defined as the  anniversary date of the Effective date of the
Reorganization Plan for SeraCare.  The options will vest at the rate  of  one-
third per  year  and  are  contingent upon  the  company achieving   the
projected   operating   results   reflected  in   the Confidential Memorandum
attached herewith except that if the indicated funding is not  provided in
timely fashion for the  acquisition of the indicated centers  reflected in  that
Confidential Memorandum,  then a calculation will be  made utilizing the
projected results  of the base six  centers (which  includes  corporate
overhead)  plus  a pro  rated calculation  of the  projected  operating results
of the  acquisition centers based upon the percentage  of the secondary
financing actually received by  SeraCare.  For  example, the projections
contemplate the acquisition of  twelve centers during  year one.  Accordingly,
at the rate of  $200,000 per  center this  acquisition program  would require
$2,400,000.   If  $1,200,000  or  50%   is  actually  funded,  then  a
calculation  will be  made utilizing  100% of  the year  one operating results
projected for the base six  centers ($365,556) plus 50% of the year one
projected operating results  for the acquisition centers (50% X $450,198 =
$225,099) with the summation of the two being ($365,556 + $225,099  = $590,655).
 Accordingly, $590,655  will be  the objective criteria for  vesting of  one
third  of the  options if  $1,200,000 of secondary financing is actually
received  by SeraCare in year one.  If SeraCare  is  sold,  merged,
consolidated  with  another  company  or reorganized  to the  extent that  there
is a  50% or  more change  in ownership, the options will become immediately
vested and exercisable.

          8.  TERM.   This Agreement is conditional  upon confirmation of  the
Plan  of Reorganization  for American  Blood Institute,  Inc., AVRE, Inc.  and
Binary  Associates, Inc. and  approval by  the Federal Bankruptcy  Court.   The
term  shall  be  for  the three  year  period beginning  on   the "Effective
Date"   of  the  Confirmed   Plan  of Reorganization and ending thirty six
months after the "Effective Date" unless this Agreement is terminated at an
earlier date per Section 9.

termination date.

               C. OTHER EVENTS.  Other events which will result in the

                    a physical and/or mental condition or   impairment  for
                    one  hundred   eighty  (180) consecutive days during the
                    term of this Agreement or  120  consecutive days  in  any

                    his duties hereunder,  other than by reason of a physical or
                    mental condition prior to the time that a disability occurs.

compensation which  would be due to complete the three year term of this
agreement, including any and all compensation, warrants,  options or  bonus
compensation, plus  the continuation  of benefits for  a period of  twelve

excess of $920,549  in year one following  the Effective Date of the 
Reorganization Plan, $2,590,160 in year two, $4,384,187 in year three, 
$6,244,536 in year four,  and $8,166,626 in year five to a bonus pool to be 
paid pro rata to management on the basis of salaries. Olson shall be a 
participant in this Management Bonus Pool during the term of this agreement.
          
          6.   FRINGE BENEFITS.   Olson shall  receive four  (4) weeks paid 
vacation  per year  during the course  of this  Agreement.  Olson will  also 
receive  company paid:  sick pay,  group health  insurance, dental  care, 
vision care, disability  insurance, life  insurance and such  other benefits  
in the amounts and  as may  be provided  in the ordinary course to the 
Corporation's other senior executives.
          
          7.  STOCK AND WARRANT GRANT.   Olson shall be granted 42,110 shares 
of common  stock of  SeraCare (SeraCare  is herein  defined as AVRE, Inc., 
Binary Associates,  Inc., American Blood  Institute, Inc. and any post 
emergence replacement  or successor corporation or entity into which the 
Plasma Operations of Avre, Inc. and Binary Associates, Inc. are transferred, 
placed, controlled, merged or which are acquired by) and  stock options to  
purchase 28,073  shares of common  stock in SeraCare for a calculated price 
which is the mean average between $.74 and the  weighted average of the  
closing bid price for  the Company's stock for  the thirty  trading days  
prior to  the vesting  date.  The vesting date is defined as the  anniversary 
date of the Effective date of the Reorganization Plan for SeraCare.  The 
options will vest at the rate  of  one-third per  year  and  are  contingent 
upon  the  company achieving   the projected   operating   results   reflected 
 in   the Confidential Memorandum attached herewith except that if the 
indicated funding is not  provided in timely fashion for the  acquisition of 
the indicated centers  reflected in  that Confidential Memorandum,  then a 
calculation will be  made utilizing the projected results  of the base six  
centers (which  includes  corporate overhead)  plus  a pro  rated calculation  
of the  projected  operating results of the  acquisition centers based upon 
the percentage  of the secondary financing actually received by  SeraCare.  
For  example, the projections contemplate the acquisition of  twelve centers 
during  year one.  Accordingly, at the rate of  $200,000 per  center this  
acquisition program  would require $2,400,000.   If  $1,200,000  or  50%  is  
actually  funded,  then  a calculation  will be  made utilizing  100% of  the 
year  one operating results projected for the base six  centers ($365,556) 
plus 50% of the year one projected operating results  for the acquisition 
centers (50% X $450,198 = $225,099) with the summation of the two being 
($365,556 + $225,099  = $590,655).  Accordingly, $590,655  will be  the 
objective criteria for  vesting of  one third  of the  options if  $1,200,000 
of secondary financing is actually received  by SeraCare in year one.  If 
SeraCare  is  sold,  merged, consolidated  with  another  company  or 
reorganized  to the  extent that  there is a  50% or  more change  in 
ownership, the options will become immediately vested and exercisable.
          
          8.  TERM.   This Agreement is conditional  upon confirmation of  the 
Plan  of Reorganization  for American  Blood Institute,  Inc., AVRE, Inc.  and 
Binary  Associates, Inc. and  approval by  the Federal Bankruptcy  Court.   
The term  shall  be  for  the three  year  period beginning  on   the  
"Effective Date"   of  the  Confirmed   Plan  of Reorganization and ending 
thirty six months after the "Effective Date" unless this Agreement is 
terminated at an earlier date per Section 9.

Board of Directors, to  correct, disassociate, cease or otherwise alter any 
actions, associations, insubordination, failure to comply  with instructions, 
failure  or other action or  omission to act  which, in  the  opinion  of the 
Board  of Directors,  materially affects   or  may   materially  affect   the 
Corporation's   business operations.  "Actions  Deemed Not  in the  Best 
Interests"  shall also include  the   association  by  Olson  with

is terminated for  "Actions Deemed Not  in the Best Interests"  as herein 
defined, Olson shall receive twelve  months severance pay and no other 
compensation other than the receipt  of any options which have already vested 
as of the termination date.
               
               C. OTHER EVENTS.  Other events which will result in the

                   this Agreement or  120  consecutive days  in  any  365 day 
                   period during the term.

               3.  The  date  on  which Olson  voluntarily  ceases  to perform
                   his duties hereunder,  other than by reason of a physical or
                   mental condition prior to the time that a disability occurs.

consolidated  or  materially  reorganized  (within the  term  of  this 
Agreement and Olson's position is  eliminated, the Company will pay to Olson

<PAGE>

Any unilateral termination of Olson  by the Corporation other than for 
"Cause", "Actions  Deemed Not in  the Best Interests", or  the reasons

breach of this agreement,  the pre-agreed remedy for which is the payment in  
cash within thirty (30) days of  such termination, the full compensation which 
 would be due to complete the  three year term of  this  agreement, including  
any  and  all compensation,  warrants, options or bonus compensation, plus the 
continuation of benefits for a period of  twelve months. If terminated for  
"Actions Deemed  Not in the  Best  Interests",  the  Corporation  must  show  
that  it  has  a reasonable basis for believing that the actions or 
associations are or could be materially detrimental to the Corporation.

                   10.   NO SOLICITATION  OF EMPLOYEES.   During the  period of
this Agreement  and for  two (2) full  years following  termination of this
Agreement,  Olson shall  not, for any  reason either  directly or indirectly,

indirectly, compete with  SeraCare either directly through  owning  and 
operating  a   plasma  center,  or  by  being  a significant investor,  officer
or  key employee  of any  company which competes  with the  Corporation.  On  a
geographic  basis, compete  is defined to mean being in the plasma collection
business within a fifty mile radius of an existing SeraCare collection center.
                   
                   12.   WITHHOLDING.   Olson  authorizes  the  Corporation  
to withhold  and/or  deduct  from his  compensation  (including,  without 
limitation,  salary  and wages),  deductions  to  recover any  amounts loaned

terms  of said loan  or  payment, must  be  repaid to  the Corporation  
including, without limitation,  loans of  money and  the value of  any of the 
Corporations property taken but not  returned by Olson.  Corporation shall

sell to Purchaser, upon the terms and subject to the conditions set forth
herein, the Transferred Assets (defined below) including the seller's startup
blood plasma donor centers located in (i) Clearfield, Utah (the "Clearfield
Center") and (ii) Raleigh, North Carolina (the "Raleigh Center"); and

     WHEREAS, Purchaser and Seller have made and entered into that certain
Employment Agreement dated September 3, 1996, a copy of which is attached as
Exhibit A.

                                 AGREEMENTS

     Seller agrees to sell to Purchaser all rights and interests in leases,
leasehold improvements, fixed assets and/or any other personal property
attributable of both the Clearfield Center and the Raleigh Center currently

ASSETS TO BE ACQUIRED. On the Closing Date, as defined herein, Seller shall
assign, transfer, convey and deliver to Purchaser an assignment of the leases,
leasehold improvements, plus ownership in any and all other rights or assets
attributable to those locations, including the rights to any FDA or QPP licenses
and/or certifications which attach or may attach to those locations, including
the right to file for such licenses and/or certifications if they have not

Seller also agrees to complete the process of establishing both startup
locations as operational plasma collection centers by opening the doors as a
plasma collection center in both locations within a reasonable period of time
not to exceed 120 days from the Closing Date.

In the event that Seller (aka Rabe) voluntarily ceases to be an employee of

ASSUMPTION OF CERTAIN LIABILITIES. Purchaser hereby assumes and agrees to
perform and discharge all liabilities and continuing obligations of the Seller
specific to the Clearfield Center and Raleigh Center and disclosed herein as
follows:

a. the real estate leases specific to the Clearfield Center and the Raleigh 
   Center as listed on Schedule 2 attached hereto under the heading Leases; and

b. all other contracts, agreements policies, licenses, permits and
   certifications in effect on the Closing Date and which are listed on 
   Schedule 2 attached hereto under the heading "Other Contracts and 
   Obligations".

c. Other than those liabilities and obligations listed on Schedule 2, Purchaser
   assumes no responsibility for any other obligation.

                                 CONSIDERATION

BASE CONSIDERATION. As consideration to Seller, Purchaser agrees to deliver
175,000 shares of common stock of the Purchaser within fifteen days of the "Open
For Business Date" (herein defined as the date that both the Raleigh Center and
Clearfield Center have processed their first donor). Both parties agree that the
175,000 shares of common stock are predicated upon a calculated Base Value of
$262,500 ($1.50 X 175,000) and an estimated investment by the purchaser of
$135,000 in total for both centers to render them ready to open for business.
Both parties further hereby agree that to the extent that the amount of
investment by the Purchaser exceeds $135,000, a corresponding reduction will be
made in the number of shares to be issued to Seller and to the extent that the
investment required of Purchaser is less than $135,000, a corresponding increase
will be made in the number of shares to be issued to Seller. By way of example,
if the actual investment by Purchaser totals $157,500, the Base Value would be
adjusted to $240,000 and the total number of shares of common stock to be issued
to Seller on the "Open For Business Date" would be 160,000. If the actual
investment by Purchaser totals 112,500, the Base Value would be adjusted to
$285,000 and the total number of shares to be issued would be 190,000.

ADDITIONAL CONSIDERATION. In addition to the Base Consideration, Seller and
Purchaser hereby agree on certain performance criteria which will serve as the
basis for Additional Consideration of a maximum of 125,000 shares of common
stock of Purchaser if all performance criteria as hereinafter defined are met.
Accordingly, if Clearfield Center and Raleigh Center in total generate a net
profit before taxes of $310,000 for the measurement period of twelve months
ending on the last day of eighteenth month following the Closing Date, Seller
shall receive as additional consideration 62,500 shares of common stock of
Purchaser. Further, if Clearfield Center and Raleigh Center in total generate a
net profit before taxes of $310,000 for the measurement period of twelve months
ending on the last day of thirtieth month following the Closing Date, Seller
shall receive as additional consideration another

                                       3
<PAGE>

62,500 shares of common stock of Purchaser. The maximum Additional 
Consideration to be delivered by Purchaser to Seller under this Agreement is 
125,000 shares of common stock of Purchaser if the Clearfield Center and the 
Raleigh Center generate a net profit before taxes of $310,000 or more for 
each of the two twelve month periods.

In the event that the Employment Agreement between Seller (referred to as 
Rabe in the Employment Agreement attached herewith as Exhibit A) and 
Purchaser (referred to as the Corporation in the Employment Agreement 
attached herewith as Exhibit A) is terminated for cause and the performance 
criteria referred to above are met, Seller shall be entitled to receive the 
Additional Consideration referred to above.

confidential information concerning the Business.

and shall cause their respective Affiliates to, cooperate fully in the

<PAGE>

other any records and other information requested by such parties in connection
therewith as well as access to, and the cooperation of, their respective
accountants.  Silver State and SeraCare shall, and shall cause their respective
Affiliates to, cooperate fully in connection with any Tax investigation, audit
or other proceeding.

     5.3  SILVER STATE'S COVENANT NOT TO COMPETE.

          5.3.1     RESTRICTIONS.  In consideration of the Noncompetition
     Payment, Silver State agrees for a period of five years after the Closing
     Date, Silver State shall not, directly or indirectly, within a 50 mile
     radius of Las Vegas, Nevada, compete with, assist any Person in competing
     with or acquire an interest in any Person competing with, any product
     presently manufactured and distributed by Silver State, whether as an
     owner, shareholder, joint venturer, partner, officer, employee, consultant,
     agent or otherwise. Nothing contained in this Section 5.3 shall prohibit
     Silver State or its Affiliates from holding and making investments in
     securities of any corporation or limited partnership whose securities are
     traded in a generally recognized market, provided, Silver State's or such
     Affiliate's equity interest therein does not exceed five percent (5%) of
     the outstanding shares or interests in such corporation or partnership.

          5.3.2     SPECIAL REMEDIES AND ENFORCEMENT. Silver State and SeraCare
     agree that a breach by Silver State of any of the covenants set forth in
     this Section 5.3 could cause irreparable harm to SeraCare, that SeraCare's
     remedies at law in the event of such breach would be inadequate, and that,
     accordingly, in the event of such breach, a restraining order or injunction
     or both may be issued against Silver State, in addition to any other rights
     and remedies that are available to .  In connection with any such action or
     proceeding for injunctive relief, Silver State hereby waives the claim or
     defense that a remedy at law alone is adequate and agrees, to the maximum
     extent permitted by Law, to have each provision of this Section 5.3
     specifically enforced against Silver State and consents to the entry of
     injunctive relief against Silver State enforcing or restraining any breach
     or threatened breach of this Section 5.3.

          5.3.3     SEVERABILITY.  If this Section 5.3 is more restrictive than
     permitted by the Laws of any jurisdiction in which SeraCare seeks
     enforcement hereof, this Section 5.3 shall be limited to the extent
     required to permit enforcement under such Laws.  In particular, the parties
     intend that the covenants

<PAGE>

     contained in Section 5.3.1 shall be construed as a series of separate
     covenants, one for each county and city in which the Business has been
     carried on and in which SeraCare conducts a similar business after the
     Closing Date.  Except for geographic coverage, each such separate covenant
     shall be deemed identical in terms.  If, in any proceeding, a court or
     arbitrator shall refuse to enforce any of the separate covenants, then such
     unenforceable covenant shall be deemed eliminated from this Section 5.3 for
     the purpose of those proceedings to the extent necessary to permit the
     remaining separate covenants to be enforced.  If the provisions of this
     Section 5.3 shall ever be deemed to exceed the duration or geographic
     limitations or scope permitted by applicable law, then such
     provisions shall be reformed to the maximum time or geographic limitations
     in scope, as the case may be, permitted by applicable Law.

          5.3.4     RESPONSIBLE HEAD TO FDA.  Silver State shall provide without
     charge to SeraCare the services of the acting "responsible head" to the FDA
     for a maximum of 90 days or until a new "responsible head" is designated
     for the Business.  SeraCare agrees to indemnify Silver State for the
     services of the "responsible head" according to the provisions of Article 6
     below.

                                   ARTICLE 6
                                INDEMNIFICATION

     6.1  OBLIGATIONS OF SILVER STATE.

          Silver State agrees to indemnify and hold harmless SeraCare and its
directors, officers, employees, affiliates, agents and assigns from and against
any and all Losses, directly or indirectly, as a result of, or based upon or
arising from:

           (a)  any breach of any representation, warranty or covenant of 
Silver State made in this Agreement; or

           (b)  any liability or obligation of, or claims against, Silver 
State or the Business other than the Assumed Liabilities.

     6.2  PROCEDURE.

           (a)  NOTICE.  Any party seeking indemnification with respect to 
any Loss shall give notice to the party required to provide indemnity 
hereunder (the "Indemnifying Party").

<PAGE>

           (b)  DEFENSE. If any claim, demand or liability is asserted by any 
third party against any Indemnified Party, the Indemnifying Party shall, upon 
the written request of the Indemnified Party, defend any actions or 
proceedings brought against the Indemnified Party in respect of matters 
embraced by the indemnity with counsel satisfactory to the Indemnified Party. 
If, after a request to defend any action or proceeding, the Indemnifying 
Party neglects to defend the Indemnified Party, a recovery against the latter 
suffered by it in good faith, is conclusive in its favor against the 
Indemnifying Party, provided however that, if the Indemnifying Party has not 
received reasonable notice of the action or proceeding against the 
Indemnified Party, or is not allowed to control its defense, judgment against 
the Indemnified Party is only presumptive evidence against the Indemnifying 
Party.  Each party hereto, to the extent that it is or becomes an 
Indemnifying Party, hereby stipulates that a judgment against the Indemnified 
Party shall be conclusive upon the Indemnifying Party.  The parties shall 
cooperate in the defense of all third party claims which may give rise to 
Indemnifiable Claims hereunder.  In connection with the defense of any claim, 
each party shall make available to the party controlling such defense, any 
books, records or other documents within its control that are necessary or 
appropriate for such defense.

           (c)  ADJUSTMENTS FOR INSURANCE PROCEEDS.  The amount of any Loss 
entitling a party to indemnification under this Article 6 shall be reduced by 
the amount of any insurance proceeds recovered by the Indemnified Party for 
such Loss, net of all costs and expenses incurred in collecting such 
insurance proceeds (including, without limitation, reasonable attorneys' 
fees).  Nothing in this Section 6.2 shall be deemed to obligate any person to 
maintain any insurance or to pursue any claim against any insurer or third 
party.

     6.3  NOTICE BY SILVER STATE.  Silver State agrees to notify SeraCare of any
liabilities, claims or misrepresentations, breaches or other matters covered by
this Article 6 upon discovery or receipt of notice thereof (other than from ),
whether before or after Closing.

     6.4 OFFSET.  The principal amount of the Promissory Note shall be reduced
in the amount of any expenses, liabilities or obligations relating to the pre-
Closing operations of the Business that are paid by SeraCare after the Closing
only by agreement of Silver State or by the amount of any indemnification
payment required by Silver State under Section 6.2(b).

                         AMENDED RESTATED LOAN AGREEMENT


         THIS AMENDED AND RESTATED LOAN AGREEMENT ("Agreement") is made
effective the 5th day of February, 1996, between CVD Financial Corporation, a

"Borrowers."

                                   WITNESSETH

         A.    SI is a party to that certain Comprehensive Loan Facility and
Security Agreement, dated October 1, 1993 (the "Original Loan Agreement"), under
which Lender made a revolving loan to SI in the amount of $1,500,000 (the
"Original Revolving Loan") and a term loan in the amount of $1,000,000 (the
"Original Term Loan") to the Borrower, represented by an Original Revolving Loan
Note in the principal amount of $1,500,000, dated October 1, 1993 (the
"Original Revolving Note") and an Original Term Loan Note in the principal
amount of $1,000,000, dated October 1, 1993 (the "Original Term Note"). On
October 5, 1993, AVRE and Binary ratified the Original Loan Agreement, Original
Revolving Note and Original Term Note and agreed to repay all sums due
thereunder and provided Lender with security therefor as reflected in that
certain Agreement to be Bound by Comprehensive Loan Facility and Security
Agreement, dated October 5, 1993.

11 of title 11 of the United States Code (Case No. LA 94-11730-AA). Binary and
AVRE also filed voluntary chapter 11 petitions on January 7, 1994, as Case Nos.

              2.1.1 CONSOLIDATED LOAN AMOUNT. The Consolidated Loan will be
evidenced by the Consolidated Note in the face amount of One Million One Hundred
Fifty Thousand Dollars ($1,150,000). Lender acknowledges the receipt from
Borrowers, concurrent with the execution hereof, of the sum of $625,000 which
has been first applied to all the outstanding amounts due under the Original
Revolving Note then to amounts due under the Original Loan Agreement. CVD

Except for the amounts represented by the Consolidated Note, from and after the

deemed to be amended and restated in full, modified and entirely controlled by
the terms of the Loan Documents, whether consisting of principal, interest,
default interest, late charges, costs of collection, attorneys' fees or other
sums. The Warrants, and the rights of Lender thereunder, are canceled. Upon the
Effective Date of this Agreement, and after receipt by Lender of $625,000, the
total amount due to Lender by Borrowers shall be the principal sum of One
Million One Hundred Fifty Thousand Dollars ($1,150,000).

              2.1.2 INTEREST. The Consolidated Note will bear interest on the
unpaid principal balance accrued from the Effective Date of this Agreement at
the Note Rate calculated on the basis of the actual days elapsed based on a per
diem charge computed over a year composed of three hundred sixty (360) days.
Interest under the Consolidated Note, accrued through the last day of each
month, will be paid on the first day of the succeeding calendar month.

              2.1.3 AMORTIZATION. The unpaid principal balance of the
Consolidated Note will be paid in consecutive quarterly installments of
$82,142.86 payable on May 1, August 1, November 1 and February 1 of each year

         2.3 NO READVANCES. The Consolidated Loan shall not be a revolving
credit and Borrowers shall not be entitled to redraw upon or to obtain

the Lender hereunder. As of the date hereof the Consolidated Loan has been fully

business.

         4.9   REORGANIZATION. AVRE and Binary will not liquidate, dissolve,

and Binary. Prior to the shares of SI trading on any of the following national

transaction or reorganization which results in an entity becoming the parent of
or holding, directly or indirectly, an equity interest of over thirty percent
(30%) in SI prior to full payment of all obligations to Lender under the Loan
Documents, then such parent or entity (in addition to SI) must become a Borrower
and assume the Consolidated Loan within thirty (30) days and fulfil all of SI's
obligations under the Loan Documents. It is the Borrowers' intent for SI to
issue shares to be traded on a recognized securities exchange. SI will not
liquidate, dissolve or materially change the general character of its business.
Notwithstanding the foregoing, SI may establish and invest in Affiliates which
are wholly-owned subsidiaries of SI consistent with the provisions of this
Agreement and, specifically, the limitations of paragraphs 4.10 and 4.11 hereof
so long as no Event of Default shall have occurred and be continuing.

          4.10  CORPORATE ACTIONS. The Borrowers will not:

                (a)   Declare or pay dividends on account of any stock of the
Borrowers, except that SI may issue warrants, options, stock, rights or any
other form of equity security as a dividend;

                (b)   Permit AVRE or Binary to directly or indirectly, make or
commit to make investments of any kind or capital expenditures or expenditures
for the lease or rental of real or personal property during any fiscal year
which shall exceed in the aggregate Two Hundred Thousand Dollars ($200,000),
except for new acquisitions of centers or startup Facilities conducting Blood
Business which becomes part of Lender's Collateral, and Borrowers execute and
deliver all reasonable Security Agreements in substantially similar form to the
Loan Documents to grant the Lender a perfected first priority lien and security
interest therein;

                (c)   Without Lender's prior consent, the Borrowers will not 
sell, transfer, liquidate, assign or otherwise dispose of the Collateral or any 
interest therein, except as to (i) sales of Inventory in the ordinary course of 
business; (ii) one or more

                                      -15-

<PAGE>

sales of assets outside the ordinary course of business in any fiscal year
having an aggregate book value of Seventy-Five Thousand Dollars ($75,000) or
less; or (iii) a sale of an Existing Facility provided that the following
conditions are met: (a) Lender must receive the purchase price less costs of
sale (the "Net Sale Proceeds"); (b) all cash proceeds of sale due on sale
closing after deducting costs of sale ("Cash Sale Proceeds") are paid to Lender
at closing; (c) the sale will provide Lender with at least Two Hundred Thousand
Dollars ($200,000) in Cash Sale Proceeds OR Borrowers will pay to Lender the
difference between Two Hundred Thousand Dollars ($200,000) and the Cash Sale
Proceeds concurrently with the closing of the sale; (d) Borrowers disclose all
relations with and provide information concerning the identity of the proposed
purchaser to the extent reasonably satisfactory to Lender so that Lender can
verify that the proposed purchaser is in no way related to or affiliated with
one or more of the Borrowers; (e) the purchaser must be a bona fide third party
and cannot be an Affiliate or affiliated with an officer, director or
shareholder of any Borrower or Affiliate; and (f) before a Borrower may sell an
Existing Facility or accept a binding offer, letter of intent or agreement to do
so, the Borrower will notify Lender of all terms of sale and provide all
documents then existing reflecting the binding offer, letter of intent and
agreement, and unconditionally offer to sell the Existing Facility to Lender in
writing on the same material terms as the proposed sale to the third party
except any terms which would preclude Lender from accepting because it would
place Lender at a competitive disadvantage with respect to the exercise of the
rights of first refusal. Lender shall have thirty (30) days after receiving the
offer, letter of intent or preliminary agreement concerning the proposed sale to
the third party, during which Lender and its agents will be given full access to
conduct any due diligence concerning the proposed sale and the purchaser and to
notify Borrowers that Lender unequivocally accepts and will purchase the
Existing Facility for the same purchase price, method of purchase price payment
(subject to Lender's credit bit rights as set forth below) and material terms as
the third party, except any terms which would preclude Lender from accepting
because it would place Lender at a competitive disadvantage with respect to its
first refusal rights. After the earlier of Lender's notice of non-acceptance or
expiration of Lender's option period, Borrowers are free to complete the
transaction presented to the Lender, on the conditions set forth below in this
paragraph 4.10(c), free and clear of Lender's liens and security interests for a
period of ninety (90) days.

                    So long as Borrowers' obligations to Lender exceed the
proposed sale price of the Existing Facility to the third party, Lender may
purchase the Existing Facility and satisfy the proposed sale price by credit
bidding a sufficient amount of Borrowers' then outstanding obligations to Lender
against the sale price. Lender's credit bid will be deemed to have been made no
later than the time period scheduled for the closing of the proposed sale to the
third party.

                    With respect to a proposed sale of an Existing Facility to a
third party calling for a partial payment of the purchase price upon the closing
and deferred payments thereafter, Lender shall credit bid such amounts of
Borrowers' then


                                      -16-

<PAGE>

outstanding obligations to Lender in such amounts and such times as the proposed
third party purchaser is required to pay under the proposed sale or sooner in
Lender's discretion. In the event of such a sale of an Existing Facility, the
Borrower must take back a negotiable purchase money promissory note ("Purchase
Money Note") secured by a first priority security interest in such Existing
Facility and, if previously pledged to Lender, Lender's lien on the Leasehold.
At the sale closing, the selling Borrower must assign as Collateral such
Purchase Money Note and security documents and deliver them to Lender or Lender
shall not be required to release its liens and security interests against the
Existing Facility. In the event of a reasonable request by Borrower to retake
possession of the Purchase Money Note for purposes of collection, Lender shall
deliver it to Borrower and Borrower will take all necessary steps to continue
Lender's perfected security interest in such Collateral. Unless there is an
Event of Default, Borrower can undertake reasonable steps to enforce the
Purchase Money Note and deliver collections of the Purchase Money Note to
Lender. If the Cash Sale Proceeds were less than $200,000 on closing, Borrower
shall pay Lender the difference between $200,000 and the Cash Sale Proceeds at
closing. Borrowers shall remit the full amount of each payment under the
Purchase Money Note to Lender within ten (10) days of receipt until Lender has
received a total amount equal to the Net Sale Proceeds. Thereafter, Borrower may
recoup their prior payments to Lender at closing from the subsequent collections
of the Purchase Money Note.

                    In the event the sale of the Existing Facility to the third
party is in an amount in excess of all of Borrowers' then outstanding
obligations to Lender, Lender may credit bid the remaining obligations of
Borrowers to Lender and pay the remaining portion of the purchase price in cash
in a manner consistent with the other provisions of this Paragraph, except that
Lender's obligations to pay cash shall not arise until all of Borrowers' then
outstanding obligations to Lender have first been satisfied in full.

              (d)   Permit AVRE or Binary to transfer, sell, liquidate, assign
or otherwise dispose of any license or permit to conduct a Blood Business
without Lender's prior approval, except as permitted hereby;

              (e)   Have outstanding accounts receivable (except as permitted
by subparagraph 1) of this paragraph 4.10), loans or other advances owing to any
Borrower by any Affiliate, shareholders, directors, officers, consultants or
employees of any Borrower or any Affiliate;

              (f)   Permit any ownership interest in AVRE, Binary or a
subsidiary of AVRE or Binary or other Affiliate to be owned or held, in whole or
in part, by any other person or entity other than SI or, as applicable, AVRE or
Binary;

              (g)   Permit payment by AVRE or Binary, of any salary, bonus,
compensation, expense sharing, tax reimbursement, management fee, overhead


                                      -17-

allocation (including office rent expenses), or other payment of any kind
whatsoever to SI (except payments for obligations owed to Lender), any
Affiliate, any shareholder, director, officer, consultant or employee of SI or
any Affiliate except for payments by AVRE or Binary for management or overhead
fees which shall not exceed (i) $70,000 per month, and (ii) $840,000 in any
calendar year. It is understood that for such fees AVRE and Binary will be
provided such general and administrative services of at least the scope and
quality as are being currently provided so that neither AVRE nor Binary will
incur any other general or administrative expenses or any other expenses for
such services.

               (h)    Except as approved in writing by Lender, which approval
may be withheld for any reason, invest in or permit the operation by any
Affiliate of any Blood Business other than a Blood Business conducted at
facilities operated by an Affiliate, directly or indirectly, which is a wholly-
owned subsidiary of SI other than AVRE or Binary.

              (i)     Permit any Affiliate to conduct Blood Business within ten
(10) miles of an Existing Facility, except under the following conditions:

                      (1)   Lender shall be first notified that the Affiliate is
engaging in the Blood Business;

                      (2)   The Borrowers provide the Lender with the historical
operating information for such Existing Facility, including production volume,
gross revenue and operating income for each of the previous twelve (12) months.

                      (3)   The Affiliate shall have first executed a Negative
Pledge Agreement;

                      (4)   At Lender's request, such Affiliate adheres to the
same reporting requirements of AVRE and Binary as set forth in paragraphs 4.3
through 4.5 of this Agreement; and

                      (5)   The Affiliate first certifies to Lender in writing
that it will not violate the unfair trade practice laws of the State where is it
located.

              (j)     Permit any Existing Facility to substantially curtail its
Blood Business operation or close an Existing Facility unless Borrowers first
pay Lender Two Hundred Thousand Dollars ($200,000) prior to or contemporaneously
with Borrowers' decision to substantially curtail the operations of or close the
Existing Facility which may be applied by Lender in its discretion as permitted
by the Loan Documents.;


                                      -18-

<PAGE>

              (k)    Knowingly permit any Affiliate to offer Blood Business or
other products and services on terms, including without limitation, price and
quality, that would place the services and products provided by the Existing 
Facilities at a competitive or economic disadvantage with those offered at the 
facilities of such Affiliate;

              (l)    Permit SI or any Affiliate to engage in purchases, sales or

receipt of any investment from SI.

         4.12 OTHER AGREEMENTS. The Borrowers will not enter into any agreement

with the terms of the Loan Documents or the ability of any Affiliate to comply
with the Negative Pledge Agreement.

         4.17 BANKRUPTCY; ADVANCE WAIVER. In the event any Borrower (or any
transferee or successor of any Borrower) files a bankruptcy proceeding or
attempts to reopen or modify the Plan to affect the treatment of Lender
postconfirmation, or has commenced against it any involuntary bankruptcy
proceeding which is not dismissed within thirty (30) days, at any time after
execution of this Agreement and before the earlier of: (i) a period of two (2)
years; or (ii) seventy-five percent (75%) of the principal indebtedness owing to
Lender under the Consolidated Note has been repaid, and subjects all or any part
of the Collateral to the jurisdiction of the United States Bankruptcy Courts, as
a substantial consideration for Lender's consent to the terms of the Settlement
Agreement, the Bankruptcy Plan and acceptance of the Loan Documents, Lender
shall be entitled to immediate and unconditional relief from the automatic stay
(11 U.S.C. Section 362) in order to pursue all legal and equitable remedies
hereunder, including any foreclosure proceeding against the Collateral and any
other security for the Consolidated Note or other Loan Documents, and the filing
of such proceeding shall be deemed consent to such relief by all Borrowers or
the owner of the Collateral. Lender and Borrowers expressly acknowledge and
agree that this provision neither directly nor indirectly waives, prohibits or
limits the right or ability of Borrowers (or any transferee or successor of
Borrowers) to file any bankruptcy proceeding.

     5.  `REPRESENTATIONS; WARRANTIES. The Borrowers jointly and severally
represent and warrant to the Lender as follows:

         5.1  OWNERSHIP. The Borrowers are the sole owners of the Collateral
free from all claims, liens, security interests, encumbrances and title
retention devices, except possible liens on the Vacant Parcels. The Borrowers
will defend title to the Collateral against all claims and demands of any person
which are adverse to the Lender as long as the Consolidated Loan has not been
paid in full.

         5.2  LITIGATION. To the best of Borrowers' knowledge, other than the
Bankruptcy Proceeding, there is no action, suit, proceeding or investigation
pending or threatened against the Borrowers or the Collateral (except as listed
in Schedule "J"). In addition, Borrowers are not aware of litigation which might
materially and adversely affect the Borrowers or the Collateral or result in any
substantial liability not adequately covered by insurance or impair the ability
of Borrower to carry on Borrowers' business as the same is conducted as of the
date hereof.

         5.3  NO DEFAULT. Execution and delivery by the Borrowers of, and the
performance by the Borrowers, of its obligations under this Agreement and each
of the Loan Documents have been authorized by all necessary action and do not
and to the best of Borrowers' knowledge will not: (a) violate or conflict with
any provision of any contract, lease or other agreement or document to which any
Borrower is a party or by which any of its assets or the Collateral are bound;
(b) result in or require the creation of any lien, claim, charge or other right
of others of any kind on or with respect to any property now or hereafter owned
or leased by any Borrower other than the liens granted to the Lender; or (c)
violate any provision of any law or regulation presently in effect.

         5.4  FINANCIAL INFORMATION. The financial information to be delivered
to the Lender relating to the Borrowers and the Collateral is correct, complete
and fairly represents the financial condition and the results of operations of
the Borrowers and the value of the Collateral as of the dates of such financial
information and there has occurred no material adverse change in such financial
information.

         5.5  VALIDITY. ENFORCEABILITY AND PERFECTION. As already approved by
the Bankruptcy Court's confirmation Order in the Bankruptcy Proceedings, (i) the
Loan Documents constitute the legal, valid and binding obligations of the
Borrowers enforceable against the Borrowers in accordance with their respective
terms; (ii) the Lender has good, valid and perfected first priority security
interests in the Collateral described in the Security Agreements (with the
possible exception of the Vacant Parcels), subject to paragraph 1.11.11 and the
provisions of paragraph 4.7(a), (c) and (d) of this Agreement; and (iii) Lender
has a good, valid and perfected first priority security interest in and to the
shares of AVRE and Binary pledged to Lender under the Stock Pledge Agreement. To
the best of Borrower's knowledge after appropriate


                                      -21-

applicable to the Borrowers or the Collateral including, without implied
limitation, all state and federal securities laws, the Employee Retirement
Income Security Act of 1974, as amended, the Fair Labor Standards Act,
Regulations of 1974, as amended, the Fair Labor Standards Act, Regulations G, T,

acquiring or entering any new lease or purchase of property, Borrowers shall
make reasonable inquiry into compliance with all Environmental Laws and any
claims for remediation of Hazardous Substances with respect to any new property
to be owned or occupied by any Borrower.

         5.9  DISCLOSURE. No representation or warranty made by the Borrowers in
the Loan Documents contains any untrue statement of a material fact or omits to
state any material fact necessary to make the statements therein not misleading.

Collateral (excluding a third party to whom one or more Borrowers is in
contractual privity or to whom such Borrower is a direct obligor); (ii) such

    8.   REMEDIES. On the occurrence of an Event of Default, in addition to any
other rights and remedies which the Lender might hold under the terms of any one
or more of the Loan Documents, the Lender will have the following remedies to
the full extent permitted by law:

         8.1  ACCELERATION OF MATURITY. The Lender may, at the Lender's option,
terminate any or all obligations of the Lender hereunder and/or declare the
Consolidated Note and all other amounts owing by the Borrowers to the Lender to
be immediately due and payable, demand performance of all other obligations of
the Borrowers under the Loan Documents and proceed to selectively and
successively enforce any one or more of the Lender's rights under the Loan
Documents.


                                      -27-

<PAGE>

         8.2  SELECTIVE ENFORCEMENT. In the event the Lender elects to
selectively and successively enforce the Lender's rights under any one or more
of the Loan Documents, such action will not be deemed a waiver or discharge of
any other right, lien or encumbrance securing payment of the Consolidated Note.
Lender may proceed against the Borrowers or any guarantor selectively and
without any requirement to proceed against all of them or against any of them in
any particular order.

         8.3  PERFORMANCE BY LENDER. In the event the Borrowers fail to cure or
cause to be cured any Event of Default within the time periods provided herein,
the Lender will at any time thereafter have the right, but not the obligation,
to cause the Event of Default to be cured on the Borrowers' behalf and to pay
any secured or unsecured claim (whether prior to or subordinate to the claims of
the Lender) affecting the Collateral or lease payments in such manner and at
such times as the Lender determines to be appropriate under the circumstances.
The Borrowers hereby authorize the Lender to increase the indebtedness owing by
the Borrowers to the Lender by the cost of curing any Event of Default or
satisfying any claim against the Borrowers or the Collateral and agrees that the
Loan Documents will evidence and secure payment of such costs whether or not the
total funds advanced by the Lender exceed the face amount of the Loan Documents.

         8.4  WAIVER OF DEFAULT. The Lender may, by an instrument in writing
signed by the Lender, waive any Event of Default which has occurred and any of
the consequences of such Event of Default and, in such event, the Lender, the
Borrowers will be restored to their respective former positions, rights and
obligations hereunder. Any Event of Default so waived will, for the purposes of
the Loan Documents, be deemed to have been cured and not to be continuing, but
no such waiver will extend to any subsequent or other Event of Default or impair
any consequences of such subsequent or other Event of Default. No waiver of any
Event of Default by the Lender will be implied from the failure or delay by the
Lender to take any action in respect of the Event of Default. No express waiver
of any condition precedent or Event of Default will affect any other Event of
Default or extend any period of time for performance other than as specified in
such express waiver. One or more waivers of any Event of Default will not be
deemed a waiver of any subsequent failure by the Borrowers to perform the same
provision or any other provision. The consent to or approval of any act or
request by the Lender will not be deemed to waive or render unnecessary the
consent to or approval of any subsequent similar act or request. The partial
exercise of any right or remedy under the Loan Documents will not preclude any
other or further exercise thereof or the exercise of any other right or remedy.
No course of dealing between the Borrowers and the Lender will be deemed to
amend the terms of the Loan Documents or to preclude the Lender from exercising
the rights and remedies therein contained notwithstanding such course of
dealing.

         8.5  CUMULATIVE REMEDIES. The rights and remedies of the Lender
provided by the Loan Documents are cumulative and no right or remedy will be
exclu-


                                      -28-

<PAGE>

sive of any other or of any other right or remedy which the Lender might
otherwise have by virtue of the occurrence of an Event of Default and the
exercise of any right or remedy by the Lender will not impair the Lender's
standing to exercise any other right or remedy.

         8.6  WAIVER OF MARSHALLING OF ASSETS. The Borrowers, jointly and
severally, for themselves and all who may claim through or under them, hereby
expressly waive and release all rights to have the Collateral, or any part
thereof, or any of their other properties, marshalled on any foreclosure, sale
or other enforcement of remedies, and the Lender or any court in which the
foreclosure of liens or security interests in the Collateral are sought, shall
have the right to sell the Collateral as an entirety in a single parcel.

    9.   NO FURTHER MODIFICATION. No provision hereof can be changed, waived,
discharged or terminated, except by an instrument in writing signed by the party
against whom the enforcement of the change, waiver, discharge or termination is
sought. It is understood that the Lender is under no obligation to extend the
term of any credit extended under this Agreement or any other Loan Document and
any such further modifications or extensions will be made in the Lender's sole
and absolute discretion. Any such modifications or extensions will be evidenced
by the acceptance by Lender of a written agreement having terms acceptable to
the Lender. Each of the Borrowers acknowledge that all of the terms and all of
the obligations of Lender with respect to any credit of any kind extended to the
Borrowers is fully contained in this Agreement and any other Loan Documents and
that no other understanding, written or oral, has been entered into in
connection herewith.

    10.  RELEASE OF LENDER. As additional consideration for the undertaking to
execute and deliver this Agreement, the Borrowers hereby each release and
forever discharge the Lender, the Lender's agents, servants, employees,
officers, directors, attorneys, and shareholders, as well as the respective
successors and assigns of any and all thereof (collectively, the "Released
Lender Parties") from all damage, loss, claims, demands, liabilities,
obligations, actions and causes of action whatsoever which the Borrowers, or any
of them, might now have or claim to have against the Lender, whether presently
known or unknown, and of every nature and extent whatsoever, on account of or in
any way concerning, arising out of or founded on the Original Loan Agreement, or
any document described therein or delivered in connection therewith, or any
other dealings between Borrowers and Lender, and including without implied
limitation, all such loss or damage of any kind heretofore sustained that might
arise as a consequence from the dealings between the parties.

         To the extent applicable, the Borrowers each waive the provisions of
Section 1542 of the California Civil Code which provides as follows:


                                      -29-

         "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
         NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE
         RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
         SETTLEMENT WITH THE DEBTOR"

$1,150,000.00                                            Los Angeles, California
                                                                February 5, 1996

          FOR VALUE RECEIVED, SERACARE, INC., a Delaware corporation formerly 
named American Blood Institute, Inc. ("SI"), AVRE, INCORPORATED, a Nevada 
corporation ("AVRE"), and BINARY ASSOCIATES, INC., a Colorado corporation 
("Binary"), promise to pay to the order of CVD FINANCIAL CORPORATION, a 
Delaware corporation, its successors and assigns (the "Lender") at 2121 
Avenue of the Stars, 22nd Floor, Los Angeles, California 90067, or at such 
other place as might be designated in writing by the Lender, the principal 
sum of One Million One Hundred Fifty Thousand Dollars ($1,150,000.00), or so 
much thereof as remains unpaid, together with interest thereon at a rate 
equal to the Note Rate (as hereafter defined). SI, AVRE and Binary are 
referred to herein collectively as the "Borrowers." The "Note Rate" shall be 
equal to fourteen percent (14%) per annum. Interest will be calculated on the 
basis of the actual days elapsed based on a per diem charge computed over a 
year composed of three hundred sixty (360) days.

          Principal and interest will be paid as follows: Interest on the 
unpaid principal balance hereunder accrued from the date hereof through the 
last day of each month, will be paid on the first day of each succeeding 
calendar month, commencing on March 1, 1996. The unpaid principal balance 
will be paid in consecutive quarterly installments of Eighty Two Thousand One 
Hundred Forty Two Dollars and 86/100 ($82,142.86) payable on May 1, August 1, 
November 1 and February 1 of each year during the term hereof with the first 
principal payment being due May 1, 1996. The final installment of principal 
and all accrued but unpaid interest will be due and payable at maturity on 
August 1, 1999.

          The Borrowers will have the right at any time and from time to time 
to prepay all or any portion of the unpaid principal balance of this Note 
without penalty.

          This Note is issued by the Borrowers and accepted by the Lender 
pursuant to a certain Amended and Restated Loan Agreement (the "Loan 
Agreement") between the Borrowers and the Lender dated February 5, 1996 and 
evidences the Consolidated Loan to be made pursuant to the Loan Agreement.

          The Borrowers agree that if, and as often as, this Note is placed 
in the hands of an attorney for collection or to defend or enforce any of the 
Lender's rights under this Note, the Loan Documents (as defined in the Loan 
Agreement) or otherwise relating to the indebtedness hereby evidenced, the 
Borrowers will pay the Lender's reasonable attorneys'

<PAGE>

fees, all court costs and all other expenses incurred by the Lender in 
connection therewith. The Lender may collect a late charge equal to five 
percent (5%) of each payment which is not received by the Lender within ten 
(10) days after the due date of such payment. Such late charge represents the 
estimate of reasonable compensation for the loss which will be sustained by 
the Lender arising from the Borrowers' failure to make timely payments and 
may be collected without prejudice to the rights of the Lender to collect any 
other amounts arising from the Borrowers' default in payment or to accelerate 
the maturity of the indebtedness hereby evidenced. In addition to the 
foregoing late charge, at the option of the Lender, after the occurrence of 
any Event of Default (as defined in the Loan Agreement), the unpaid balance 
of this Note will bear interest at that rate which is equal to two percent 
(2.0%) per annum in excess of the Note Rate and such interest which has 
accrued will be paid at the time of and as a condition precedent to curing 
any Default (as defined in the Loan Agreement). During the existence of any 
Default, the Lender may apply payments received on any amount due hereunder 
or under the terms of any instrument now or hereafter evidencing or securing 
payment of this indebtedness as the Lender determines from time to time.

          Payment of the indebtedness hereby evidenced is secured by certain 
liens and security interests described in the Loan Documents (as defined 
under the Loan Agreement). On the breach by the Borrowers of any provision of 
this Note, or any one or more of the Loan Documents or any other instrument 
now or hereafter evidencing or securing payment of the indebtedness hereby 
evidenced, at the option of the Lender, the entire indebtedness evidenced by 
this Note will become immediately due, payable and collectible then or 
thereafter as the Lender might elect, regardless of the date of maturity of 
this Note. Failure by the Lender to exercise such option will not constitute 
a waiver of the right to exercise the same on the occurrence of any 
subsequent Event of Default.

          The makers, endorsers, sureties, guarantors and all other persons 
who might be or become liable for all or any part of this obligation 
severally waive presentment for payment, protest and notice of nonpayment. 
Such parties consent to any extension of time (whether one or more) of 
payment hereof, release of all or any part of the collateral securing payment 
hereof or release of any party liable for the payment of this obligation. Any 
such extension or release may be made without notice to any such party and 
without discharging such party's liability hereunder. If more than one maker 
executes this Note, the liability of each of the undersigned is and shall be 
joint and several.

          The lending transaction contemplated by this Note and the Loan 
Documents has been negotiated, consummated and is to be performed in the 
State of California. This Note and the other Loan Documents (as described in 
the Loan Agreement), except to the extent otherwise provided therein, shall 
be governed by, and construed and enforced in accordance with the substantive 
law of the State of California to the fullest extent permitted by law, 
including choice of laws. Any action or proceeding arising in connection with 
this Note and the Loan Documents shall be brought in a federal or state court 
within Los

<PAGE>

Angeles County, California, and the Borrowers hereby consent to the 
jurisdiction of any federal or state court within the State of California and 
located in State of California and located in Los Angeles County, California. 
The Borrowers irrevocably and unconditionally submit to the jurisdiction 
(both subject matter and personal) of each such court and irrevocably and 
unconditionally waive (1) any objection that they might now or hereafter have 
to the venue in any such court; and (2) any claim that any action or 
proceeding brought in any such court has been brought in an inconvenient 
forum. Notwithstanding the foregoing, the Lender may, in its sole and 
absolute discretion, initiate proceedings in the courts of any other 
jurisdiction in which any Borrower may be found or in which its assets may be 
located.

          THE BORROWERS HEREBY EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY JURY OF 
ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS NOTE, ANY 
OF THE LOAN DOCUMENTS DESCRIBED HEREIN OR ANY OTHER INSTRUMENT, DOCUMENT OR 
AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (2) IN ANY WAY 
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES OR ANY 
OF THEM WITH RESPECT TO THIS NOTE, THE LOAN AGREEMENT, THE LOAN DOCUMENTS, OR 
ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN 
CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH 
CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN 
CONTRACT OR TORT OR OTHERWISE; AND THE BORROWERS HEREBY AGREE AND CONSENT 
THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY 
COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY MAY FILE AN ORIGINAL 
COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF 
THE CONSENT OF THE PARTIES THERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY

                    binding obligation of McGhee, enforceable against McGhee in
                    accordance with its terms, except as may be limited by
                    bankruptcy, insolvency, reorganization, moratorium, and
                    other similar laws and equitable principles relating to or
                    limiting creditors' rights generally.

               d.   The equipment located at the Plasma Collection Center in
                    Fort Smith, Arkansas includes all the equipment necessary to
                    conduct the business of BHM Labs. Such equipment is in
                    working order, reasonable wear and tear excepted, and there
                    exists no material defect in the condition of any of the
                    equipment. True and correct lists of the equipment owned and
                    leased by BHM Labs are attached hereto as Schedules 1 and 2,
                    respectively. 

               e.   McGhee has delivered to SeraCare a balance sheet for BHM
                    Labs at May 31, 1996, and the related statement of
                    operations and cash flows and changes in stockholder's
                    equity for the period then ended.  All such financial
                    statements have been prepared on an accrual basis and in
                    conformity with GAAP applied on a consistent basis except
                    for changes, if any, required by GAAP and as disclosed
                    therein.  The statement of operations and cash flows
                    presents fairly the results of operations and cash flows of
                    BHM Labs for the period covered, and the balance sheet
                    presents fairly the financial condition of BHM Labs as of
                    its date.

               f.   Since May 31, 1996, whether or not in the ordinary course of
                    business, there has not been, occurred or arisen any change
                    in or event affecting BHM Labs that has had or may
                    reasonably be expected to have a material adverse effect on
                    BHM Labs.

               a.   SeraCare, Inc. is a corporation duly organized, validly
                    existing and in good standing under the laws of the state of
                    Delaware, which has taken all corporate, shareholder, and
                    other action necessary to authorize the execution and
                    delivery of this agreement, and the transactions
                    contemplated hereby.  This agreement is a valid and binding
                    obligation of SeraCare, enforceable in accordance with its
                    terms except as may be limited by bankruptcy, insolvency,
                    reorganization, moratorium, and other similar laws and
                    equitable principles relating to or limiting creditors'

                    preferred stock, free and clear of all pledges, liens,
                    claims, mortgages and encumbrances.

               c.   Neither the execution and delivery of this Agreement, nor
                    the consummation of the transactions contemplated hereby
                    will constitute a violation or breach of (1) the certificate
                    of incorporation or by-laws of SeraCare, (2) any provision
                    of any contract or other instruments to which SeraCare is a
                    party or by which SeraCare's business, assets, or properties
                    may be affected or secured, or (3) any order, writ,
                    injunction, decree, statute, rule or regulation binding on
                    SeraCare.

               d.   SeraCare has delivered to McGhee financial statements for
                    1995 and for the period ending May 31, 1996.  All such

<PAGE>

                    conformity with GAAP applied on a consistent basis except
                    for changes, if any, required by GAAP and as disclosed
                    therein.  The statement of operations and cash flows
                    presents fairly the results of operations and cash flows of
                    SeraCare for the periods covered, and the balance sheets
                    present fairly the financial condition of SeraCare as of
                    their dates.

               e.   Since May 31, 1996, whether or not in the ordinary course of
                    business, there has not been, occurred or arisen any change
                    in or event affecting SeraCare that has had or may
                    reasonably be expected to have a material adverse effect on
                    SeraCare.

               f.   SeraCare is not currently a party to any loan agreement,
                    security agreement, financing statement or similar agreement
                    with a third party under which SeraCare has agreed to grant
                    the third party a security interest in or has otherwise
                    agreed to encumber the stock of BHM Labs or the assets of
                    BHM Labs.

               g.   SeraCare's representations and warranties contained herein
                    shall be true and correct on the closing date and shall be
                    made again at that time.

          12.  RESPONSIBLE HEAD/GOOD STANDING CERTIFICATE.

          (a)  RESPONSIBLE HEAD.  McGhee is currently the "responsible head"
under BHM Labs's FDA label.  After closing McGhee agrees, at the option of
SeraCare, to continue to act as and to perform the functions of the "responsible
head" under BHM Labs's label until such time as a new "responsible head" has
been approved by the FDA and the change in the ownership of the stock of BHM
Labs has been approved by the FDA.  After closing, SeraCare or BHM Labs, or
both, shall forthwith apply for and shall use their reasonable efforts to
promptly obtain FDA approval of a change of the responsible head and the change
in the stock ownership of BHM Labs.

          (b)  GOOD STANDING CERTIFICATE. McGhee agrees to deliver to SeraCare a
good standing certificate from the Arkansas Secretary of State for BHM Labs,

after the Closing, McGhee shall not, directly or indirectly, within 50 miles of
any collection center owned by SeraCare or BHM Labs, compete with, assist any

SeraCare or BHM Labs, whether as an owner, shareholder, joint venturer, partner,
officer, employee, consultant, agent or otherwise.

               (b)  SPECIAL REMEDIES AND ENFORCEMENT.  SeraCare and McGhee agree
that a breach by McGhee of any of the covenants set forth in this Section 13
could cause irreparable harm to SeraCare, that SeraCare's remedies at law in the
event of such breach would be inadequate, and that, accordingly, in the event of
such breach, a restraining order or injunction or both may be issued against
Seller, in addition to any other rights and remedies that are available to
SeraCare. In connection with any such action or proceeding for injunctive
relief, McGhee hereby waives the claim or defense that a remedy at law alone is
adequate and agrees, to the maximum extent permitted by Law, to have each
provision of this Section 13 specifically enforced against McGhee and consents
to the entry of injunctive relief against McGhee enforcing or restraining any
breach or threatened breach of this Section 13.

           (c)  SEVERABILITY.  If this Section 13 is more restrictive than
permitted by the laws of any jurisdiction in which SeraCare seeks enforcement
hereof, this Section 13 shall be limited to the extent required to permit
enforcement under such laws. If the provisions of this Section 13 shall ever be
deemed to exceed the duration or geographic limitations or scope permitted by
applicable law, then such provisions shall be


                                        6

<PAGE>

reformed to the maximum time or geographic limitations in scope, as the case may
be, permitted by applicable Law.

shall be unaffected by any investigation conducted by, to be conducted by, or
which could have been conducted by McGhee. Except as limited herein below,
SeraCare agrees to defend, indemnify and hold McGhee harmless from and against
any and all demands, claims, causes of action, losses, damages, liabilities,
costs and expenses asserted against, resulting to or incurred by McGhee by
reason of or resulting from any breach of said warranty. The liability of
SeraCare under this indemnification shall continue for the maximum period
provided by law. SeraCare's indemnity obligation shall be limited to the value
of the preferred shares immediately at closing.

               (b)  SeraCare also agrees to indemnify and hold McGhee harmless
from all claims arising from the operation of BHM Labs's business after closing,
including but not limited to any claim arising from any act or omission by an
officer, director, employee or representative of BHM Labs other than McGhee, so
long as the act or omission giving rise to the claim occurs after the date of
closing.

          15.  INDEMNIFICATION BY MCGHEE.    (a) McGhee warrants that all
statements contained herein or in any document delivered in connection with the

directors and officers harmless from and against any and all demands, claims,
causes of action, losses, damages, liabilities, costs and expenses asserted
against, resulting to or incurred by SeraCare, its shareholders, directors or
officers by reason of or resulting from any breach of said warranty.  The
liability of McGhee under this indemnification shall continue for the maximum
period provided by law.  McGhee's indemnity obligation shall be limited to the
value of the preferred shares immediately at closing.

               (b)  McGhee also agrees to indemnify and hold SeraCare harmless
from all claims arising from the operation of BHM Labs's business whether prior
to or after closing, including but not limited to any claim arising from any act
or omission by an officer, director, employee or representative of BHM Labs so
long as the act or omission giving rise to the claim occurs on or prior to the
date of closing.
 
          16.  RESIGNATION OF OFFICERS AND DIRECTORS.  At closing, McGhee shall
make available to SeraCare the written


                                        7

<PAGE>

resignation of BHM Labs current directors and officers and shall take, or cause
to be taken, such action as SeraCare may request with respect to changes in
directors and officers.

and SeraCare shall both have the right to demand specific performance on the
part of the other as a remedy for either party's breach of this agreement.

          18.  CONFIDENTIALITY.  The parties agree that the terms of this
agreement shall remain absolutely confidential.  Unless required by law, neither
party shall disclose the existence or the terms of this agreement without the
express, written consent of the other party, which consent shall not be
unreasonably withheld.

          19.  ARBITRATION.  All disputes arising out of or in connection with
this contract, which cannot be settled by mutual agreement between the parties,
shall be settled by arbitration in Fort Smith, Arkansas in accordance with the
rules in effect of the American Arbitration Association.  Within ten (10) days
from the date either party receives notice from the other party of its appointed
arbitrator, such party shall appoint its arbitrator. In the event such party has
not appointed its arbitrator within such time, the arbitration may be conducted
by the sole arbitrator appointed by the first appointing party.  In the event
such party does appoint an arbitrator within such time period, the two
arbitrators shall then appoint a third arbitrator, within ten (10) business days
from the date of appointment of the second arbitrator.  If the arbitrators are
unable to agree upon the selection of the third arbitrator within such time
period, then the appointment of such third arbitrator shall be deemed a
"controversy" and either party hereto may request the American Arbitration
Association to appoint such third arbitrator.  Any award by the Arbitrator shall
be final, binding and non-appealable.  Notwithstanding anything herein to the
contrary, the parties may apply to any court of competent jurisdiction for
injunctive relief without breach of this arbitration provision.

          20.  MISCELLANEOUS.

               a.   JOINT DRAFTING. Both McGhee and SeraCare have jointly
                    participated in the negotiations and drafting of this

          The securities represented hereby have not been registered under 
     the Securities Act of 1933, as amended, or any state securities laws and

     reasonably satisfactory to counsel for this corporation, is available.

                       SERIES A WARRANT AGREEMENT

     This Agreement (the "AGREEMENT") dated September 4, 1996 between SeraCare,
Inc., a Delaware corporation (the "COMPANY" and the "WARRANT AGENT") and those
individuals and entities purchasing the "Units" in a private offering by the
Company,

                          W I T N E S S E T H:

     WHEREAS, the Company proposes to privately offer (the "PRIVATE 
OFFERING") up to 200 Units (subject to an option for an additional 80 Units) 
to individuals and entities, each Unit to consist of five-thousand shares of 
the Company's common stock (the "Common Stock"), and two-thousand 
five-hundred warrants to purchase an additional share of Common Stock, such 
right to be evidenced by a "Series A Warrant", with the Series A Warrants 
being collectively referred to herein as the "Series A Warrants" or 
"Warrants";

     WHEREAS, exclusive of the aforesaid option, in connection with the 
proposed Private Offering, the Company anticipates its issuance of up to 
500,000 Series A Warrants to purchase up to 500,000 shares of Common Stock 
(the shares received upon exercise of the Series A Warrants are referred to 
herein as the "WARRANT SHARES");

     WHEREAS, the Company desires to provide for the issuance of certificates 
representing the Series A Warrants (a "Series A Warrant Certificate" or 
collectively the "Series A Warrant Certificates");

     WHEREAS, the Company desires to act as its own warrant agent in 
connection with the issuance, registration, transfer and exchange of Series A 
Warrant Certificates and the exercise of the Series A Warrants;

     NOW, THEREFORE, in consideration of the above and foregoing premises and 
the mutual promises and agreements hereinafter set forth, it is agreed that:

                                       1
<PAGE>

     1.   SERIES A WARRANT CERTIFICATES.

          (a)  Each Series A Warrant shall entitle the holder (the 
"Registered Holder," or, in the aggregate, the "Registered Holders") in whose 
name the certificate shall be registered on the books maintained by the 
Company to purchase one (1) share of Common Stock on the exercise thereof, 
subject to modification and adjustment as provided in Section 9 hereof.  
Series A Warrant Certificates shall be executed by the Company's Chairman, 
President or Senior Vice President and attested to by the Company's 
Secretary.  The Series A Warrant Certificates shall be immediately detachable 
from certificates representing shares of Common Stock and shall be 
distributed to the purchasers thereof concurrently with each closing of the 
Private Offering.

          (b)  Subject to the provisions of Sections 3, 5, and 7 hereof, the 
Company shall deliver Series A Warrant Certificates in required whole number 
denominations to Registered Holders in connection with any transfer or 
exchange permitted under this Agreement.  Except as provided in Section 7 
hereof, no certificates shall be issued except (i) certificates initially 
issued hereunder, (ii) certificates issued on or after their initial issuance 
date upon the exercise of any Warrant to evidence the unexercised Series A 
Warrants held by the exercising Registered Holder and (iii) Series A Warrant 
certificates issued after their initial issuance date, upon any transfer or 
exchange of certificates or replacements of lost or mutilated certificates.

     2.   FORM AND EXECUTION OF SERIES A WARRANT CERTIFICATES.

           (a)  The Series A Warrant certificates shall be dated the date of 
the original issuance of the Series A Warrants, whether on initial transfer 
or exchange or in lieu of mutilated, lost, stolen or destroyed certificates.  
The form of Series A Warrant certificate is annexed hereto as "Exhibit A."

           (b)  Each Series A Warrant certificate shall be numbered serially 
bearing "WA" as an initial designation, and subsequent to this designation 
the serial numbering of the Series A Warrant certificate should match, to the 
extent possible, the serial numbering of the Common Stock initially attached 
thereto.

           (c)  The Series A Warrant Certificates shall be manually signed on 
behalf of the Company by a proper officer thereof and shall not be valid for 
any purpose unless so signed. In the event any officer of the Company who 
executed certificates shall cease to be an officer of the Company such 
certificates may be issued and delivered by the Company or transferred by the 
Registered Holders with the same force and effect as though the person who 
signed such certificate had not ceased to be an

                                       2
<PAGE>

officer of the Company; and any certificate signed on behalf of the Company 
by any person, who at the actual date of the execution of such certificate 
was a proper officer of the Company, shall be proper notwithstanding that at 
the date of execution of this Agreement any such person was not such an 
officer.

     3.   EXERCISE.

          (a)  Subject to the provisions of Sections 5 and 9 hereof, the 
Series A Warrants, as they may be adjusted as set forth herein, may be 
exercised at a price (the "WARRANT EXERCISE PRICE") of $2.75 per share of 
Common Stock subject to adjustment, in whole or in part at any time during 
the period (the "WARRANT EXERCISE PERIOD") commencing on the date of issuance 
of the Series A Warrant and terminating on the earlier of (i) the date three 
years after effectiveness of the Initial Registration Statement, provided, 
however, that (x) if the Common Stock underlying the Warrants is not subject 
to an effective registration for an aggregate of 600 days within three years 
after the final closing of the Private Offering, then the remaining exercise 
period under this clause (i) shall be tolled until the Common Stock 
underlying the Warrants shall have been subject to an effective registration 
for an aggregate of 600 days and (y) in no event shall the Series A Warrants 
terminate under this clause (i) unless a registration statement covering the 
Warrant Shares shall have then been in effect for 45 days prior to such 
termination, and (ii) six years from the date of issuance (the "WARRANT 
EXPIRATION DATE"), unless extended by a majority vote of the Board of 
Directors for such length of time as they, in their sole discretion, deem 
reasonable and necessary.

          (b)  Each Series A Warrant shall be deemed to have been exercised 
immediately prior to the close of business on the date (each, an "EXERCISE 
DATE") of the surrender to the Company for exercise of the Series A Warrant 
certificate.  The exercise form shall be executed by the Warrant Holder 
thereof or his attorney duly authorized in writing and shall be delivered 
together with payment to the Company at its corporate offices located at 1875 
Century Park East, Suite 2130, Los Angeles, CA.   90067 (the "CORPORATE 
OFFICE"), or at any such other office or agency as the Company may designate, 
in cash or by official bank or certified check, of an amount equal to the 
aggregate Exercise Price, in lawful money of the United States of America.

          (c)  Unless Warrant Shares may not be issued as provided herein, 
the person entitled to receive the number of Warrant Shares deliverable on 
exercise shall be treated for all purposes as the holder of such Warrant 
Shares as of the close of business on the Exercise Date.  The Company shall 
not be obligated to issue any fractional share interest in Warrant Shares 
issuable or deliverable on the exercise of any Series A

                                       3
<PAGE>

Warrant or scrip or cash therefore and such fractional shares shall be of no
value whatsoever.

          (d)  Within ten days after the Exercise Date and in any event prior 
to the Warrant Expiration Date, the Company, at its own expense, shall cause 
to be issued and delivered to the person or persons entitled to receive the 
same, a certificate or certificates in the name requested by the Registered 
Holder for the number of Warrant Shares deliverable on such exercise.  No 
adjustment shall be made in respect of cash dividends on Warrant Shares 
delivered on exercise of any Series A Warrant.  All shares of Common Stock 
delivered upon the exercise of the Series A Warrants shall be validly issued, 
fully paid and non-assessable. Any Series A Warrants redelivered to the 
Registered Holder in the event of the exercise of less than all of the Series 
A Warrants pertaining to a surrendered Series A Warrant certificate, shall be 
validly issued, fully paid and non-assessable.

          (e)  The Series A Warrants shall not entitle the holder thereof to 
any of the rights of shareholders or to any dividend declared on the Common 
Stock unless such holder or holders shall have exercised the Series A 
Warrants prior to the record date fixed by the Board of Directors for the 
determination of holders of Common Stock entitled to such dividends or other 
rights.

     4.   REGISTRATION RIGHTS.

          The holders of Series A Warrants shall have the registration rights 
under the Securities Act of 1933, as amended (the "ACT"), and the rules and 
regulations promulgated thereunder by the Securities and Exchange Commission 
(the "COMMISSION"), provided for in that certain Registration Rights 
Agreement executed by the Company and the A Warrant holders on even date 
herewith (the "REGISTRATION RIGHTS AGREEMENT").  The Registration Rights 
Agreement is incorporated herein by this reference in its entirety as if 
fully set forth herein.

     5.   RESERVATION OF SHARES AND PAYMENT OF TAXES.

           (a)  The Company covenants that it shall at all times reserve and 
have available from its authorized Common Stock such number of shares as 
shall then be issuable on the exercise of all outstanding Series A Warrants.  
The Company covenants that all Warrant Shares shall be duly and validly 
issued, fully paid and non-assessable, and shall be free from all taxes, 
liens and charges with respect to the issuance thereof.

           (b)  The Company shall pay all documentary, stamp or similar taxes 
and other government charges that may be imposed with respect of the issuance 
of the Series A Warrants, and/or the issuance of any Common Stock 
constituting the Warrant Shares on the exercise of the Series A Warrants.  In 
the event the Warrant

                                       4
<PAGE>

Shares are to be delivered in a name other than the name of the initial
Registered Holder of the certificate, no such delivery shall be made unless the
person requesting the same has paid to the Company the amount of any such taxes,
charges, or transfer fees incident thereto.

     6.   REGISTRATION OF TRANSFER.

          (a)  The Series A Warrant certificates may, subject to provisions 
of the Federal Securities Laws and any applicable state securities laws, be 
transferred in whole or in part Certificates to be transferred shall be 
surrendered to the Company at its Corporate Office.  The Company shall 
execute, issue and deliver in exchange therefor the Series A Warrant 
certificates in the names and amounts that the holder making the transfer 
shall have designated in writing.  The Company shall keep transfer books at 
its Corporate Office which shall register certificates and the transfer 
thereof.  On due presentment for registration of transfer of any certificate 
at the Corporate Office, the Company shall execute, issue and deliver to the 
transferee or transferees a new certificate or certificates representing an 
equal aggregate number of securities.  All such certificates shall be duly 
endorsed or be accompanied by a written instrument or instruments of transfer 
in form reasonably satisfactory to the Company.  The established transfer fee 
for any registration of transfer of certificates shall be paid by the Warrant 
Holder or the person presenting the certificate for transfer.

          (b)  Prior to due presentment for registration or transfer thereof, 
the Company may treat the Registered Holder of any certificate as the 
absolute owner thereof (notwithstanding any notations of ownership or writing 
thereon made by anyone), and the parties hereto shall not be affected by any 
notice to the contrary.

     7.   LOSS OR MUTILATION.

          On receipt by the Company of evidence satisfactory as to the ownership
of and the loss, theft, destruction or mutilation of any Series A Warrant
certificate, the Company shall execute and deliver in lieu thereof a new
certificate representing an equal number of Series A Warrants.  In the case of
loss, theft or destruction of any certificate, the individual requesting
reissuance of a new certificate shall be required to indemnify the Company and,
at the request of the Company, to post an open-penalty insurance or indemnity
bond.  In the event a certificate is mutilated, such certificate shall be
surrendered and canceled by the Company prior to delivery of a new certificate. 
Applicants for a new certificate shall also comply with such other regulations
and pay such other reasonable charges as the Company may prescribe.


                                       5

     8.   REDEMPTION OPTION.

     The Company shall have the right and option, upon 30 days' prior written 
notice to each Registered Holder, to, at any time thereafter, call, redeem 
and acquire all or a portion of the Series A Warrants which remain 
outstanding and unexercised at the date fixed for redemption (the "Series A 
Warrant Redemption Date") at a price of $.01 per Series A Warrant if, and 
only if, the average of the closing bid and closing asked price per share of 
the Common Stock for each of the 20 consecutive trading days immediately 
prior to the mailing of said notification, and for each day thereafter until 
the Series A Warrant Redemption Date shall have exceeded 133.3% of the then 
Exercise Price.  The Series A Warrant Holders shall in all events have the 
right during the period immediately following the date of such notice and 
prior to the Series A Warrant Redemption Date to exercise the Series A 
Warrants in accordance with the provisions of Section 3 hereof.

     No call for redemption and no redemption of the Series A Warrants shall 
be made unless the Company shall have an effective registration statement 
under the Act on file during such period from the date of mailing of the 
notice of redemption through the applicable redemption date with the 
Commission and all applicable state securities commissions relating to the 
Common Stock and the Warrant Shares, except that this obligation, as it 
relates to the Warrant Shares or Common Stock, may be satisfied if such 
Warrant Shares or Common Stock, respectively, may be transferred publicly in 
accordance with Rule 144 or otherwise without registration under the Act.  In 
the event that any Series A Warrants are exercised following notice but prior 
to redemption, this call option shall be deemed not to have been exercised by 
the Company as to the Series A Warrants so exercised.

     The redemption notice shall require each Warrant Holder to surrender the 
Series A Warrants on or before the Redemption Date in accordance with the 
provisions of the redemption notice.  In the event the Series A Warrant 
Certificates representing the Series A Warrants called for redemption have 
not been surrendered for redemption and cancellation on the applicable 
redemption date, such Series A Warrants shall be deemed to have expired and 
all rights of the holders of such unsurrendered Series A Warrants shall cease 
and terminate, other than the right to receive the redemption price without 
interest; provided, however, that such right to receive the redemption price 
shall itself expire one year from the Series A Warrant Redemption Date if no 
claim is made therefor prior to such date.

     9.   ADJUSTMENT OF INITIAL EXERCISE
          PRICE AND NUMBER OF SHARES PURCHASABLE.

          For purposes hereof, the term "INITIAL EXERCISE PRICE" shall mean, 
with respect to the A Warrants, $2.75.  The Initial Exercise Price and the 
number of shares of Common Stock purchasable pursuant to the A Warrants shall 
be subject to adjustment from time to time as hereinafter set forth in this 
Section 9.

          9.1  ADJUSTMENTS.  The number of Warrant Shares purchasable upon the
exercise of the Warrants and the Exercise Price shall be subject to adjustment
as follows:

          (a)  In case the Company shall (i) pay a dividend in shares of 
     Common Stock or make a distribution in shares of Common Stock, (ii) 
     subdivide its outstanding shares of Common Stock, (iii) combine its 
     outstanding shares of Common Stock into a smaller number of shares of 
     Common Stock or (iv) issue by reclassification of its Common Stock other 
     securities of the Company, the number of Warrant Shares purchasable upon 
     exercise of the Warrants immediately prior thereto shall be adjusted so 
     that the holder shall be entitled to receive the kind and number of 
     Common Stock or other securities of the Company which it would have 
     owned or would have been entitled to receive after the happening of any 
     of the events described above, had the Warrants been exercised 
     immediately prior to the happening of such event or any record date with 
     respect thereto.  Any adjustment made pursuant to this Paragraph (a) 
     shall become effective immediately after the effective date of such 
     event retroactive to the record date, if any, for such event.

          (b)  In case the Company shall issue rights, options, warrants or 
     convertible securities to all or substantially all holders of its Common 
     Stock, without any consideration, entitling them to subscribe for or to 
     purchase shares of Common Stock at a price per share which is lower at 
     the record date mentioned below than the then Current Market Price (as 
     defined below), the number of Warrant Shares thereafter purchasable upon 
     the exercise of a Warrant shall be determined by multiplying the number 
     of Warrant Shares theretofore purchasable upon exercise of each Warrant 
     by a fraction, of which the numerator shall be (1) the number of shares 
     of Common Stock outstanding immediately prior to the issuance of such 
     rights, options or warrants plus (2) the number of additional shares of 
     Common Stock offered for subscription or purchase, and of which the 
     denominator shall be (x) the number of shares of Common Stock 
     outstanding immediately prior to the issuance of such rights, options or 
     warrants plus (y) the number of shares which the aggregate offering 
     price of the total number of shares offered would

                                       7
<PAGE>

     purchase at the Current Market Price.  Such adjustment shall be made 
     whenever such rights, options or warrants are issued, and shall become 
     effective immediately and retroactively after the record date for the 
     determination of shareholders entitled to receive such rights, options 
     or warrants.

          (c)  In case the Company shall distribute to all or substantially 
     all holders of its shares of Common Stock evidences of its indebtedness 
     or assets (excluding cash dividends or distributions out of earnings) or 
     rights, options, warrants or convertible securities containing the right 
     to subscribe for or purchase shares of Common Stock (excluding those 
     referred to in paragraph (b) above), then, in each case, the number of 
     Warrant Shares thereafter purchasable upon the exercise of the Warrants 
     shall be determined by multiplying the number of Warrant Shares 
     theretofore purchasable upon exercise of the Warrants by a fraction, of 
     which the numerator shall be the then Current Market Price on the date 
     of such distribution, and of which the denominator shall be such Current 
     Market Price on such date minus the then fair value of the portion of 
     the assets or evidence of indebtedness so distributed or of such 
     subscription rights, options or warrants applicable to one share.  Such 
     adjustment shall be made whenever any such distribution is made and 
     shall become effective on the date of distribution retroactive to the 
     record date for the determination of shareholders entitled to receive 
     such distribution.

          (d)  No adjustment in the number of Warrant Shares purchasable 
     hereunder shall be required unless such adjustment would require an 
     increase or decrease of at least one percent (1%) in the number of 
     Shares then purchasable upon the exercise of a Warrant;  PROVIDED, 
     HOWEVER, that any adjustments which by reason of this Paragraph (d) are 
     not required to be made immediately shall be carried forward and taken 
     into account in any subsequent adjustment.

          (e)  Whenever the number of Warrant Shares purchasable upon the 
     exercise of a Warrant is adjusted as herein provided, the Exercise Price 
     payable upon exercise of a Warrant shall be adjusted by multiplying such 
     Exercise Price immediately prior to such adjustment by a fraction, of 
     which the numerator shall be the number of Warrant Shares purchasable 
     upon the exercise of a Warrant immediately prior to such adjustment, and 
     of which the denominator shall be the number of Shares so purchasable 
     immediately thereafter.

          (f)  The Exercise Price of the Series A Warrants shall be 
     automatically and permanently reduced by $.10 per share each if (i) the 
     Initial Registration Statement (as defined

                                       8
<PAGE>

     in the Registration Rights Agreement) has not become effective on or 
     prior to that date which is 270 days from the Final Closing Date, (ii) 
     the Commission shall have issued a stop order suspending the 
     effectiveness of the Initial Registration Statement and the number of 
     days stop orders have been in effect, together with the number of days a 
     notice under Section 4.1(d) of the Registration Rights Agreement has 
     been issued or required to be issued, exceeds 180 days, or (iii) (A) the 
     Company for the third time, notifies or is required to notify the 
     holders of the Warrants pursuant to Section 4.1(d) of the Registration 
     Rights Agreement, or (B) a notice under such Section 4.1(d) is effective 
     or required to be effective at a time when the aggregate number of days 
     for which all such notices issued or required to be issued pursuant to 
     such Section 4.1(d) have been, or were required to be, in effect, 
     exceeds 180 days (270 days from the Final Closing Date in the case of 
     clause (i), or the date the third notice is sent or required to be sent 
     or the date on which the 180-day limit is exceeded in the case of clause 
     (ii) or (iii), is each referred to herein as an "Event Date").  
     Additionally, the Exercise Price of each Series A Warrant then 
     outstanding shall be subject to further downward adjustment in the 
     amount of $.10 each on the same day of each month following the initial 
     Event Date (or, if there is no numerically corresponding day in any such 
     subsequent month, then on the last day of such applicable subsequent 
     month) until the Registration Statement becomes effective; PROVIDED, 
     HOWEVER, that such adjustments will, in each case, cease to accrue on 
     the date which (x) the Initial Registration Statement is declared 
     effective, with respect to the adjustments for failure to be declared 
     effective by that date which is 270 days from the Final Closing Date, 
     (y) the Initial Registration Statement is no longer subject to an order 
     suspending the effectiveness thereof, with respect to adjustments for 
     the failure to remain effective or (z) a notice issued, or required to 
     be issued, pursuant to Section 5.1(d) is no longer effective or required 
     to be effective, with respect to adjustments payable pursuant to clause 
     (iii) above.  In no event shall the Series A Warrant exercise price be 
     adjusted below $1.50 solely due to this Section 9.1

          (g) Whenever the number of Warrant Shares purchasable upon the 
     exercise of a Warrant or the Exercise Price is adjusted as herein 
     provided, the Company shall cause to be promptly mailed to the holder by 
     first class mail, postage prepaid, notice of such adjustment or 
     adjustments and a certificate of a firm of independent public 
     accountants selected by the Board of Directors of the Company (who may 
     be the regular accountants employed by the Company) setting forth the 
     number of Warrant Shares purchasable upon the

                                       9
<PAGE>

     exercise of a Warrant and the Exercise Price after such adjustment, a 
     brief statement of the facts requiring such adjustment and the 
     computation by which such adjustment was made.

          (h)  For the purpose of this Subsection 9.1, the term "Common 
     Stock" shall mean (i) the class of stock designated as the Common Stock 
     of the Company at the date of this Agreement or (ii) any other class of 
     stock resulting from successive changes or reclassifications of such 
     Common Stock.  In the event that at any time, as a result of an 
     adjustment made pursuant to this Section 9, the holder shall become 
     entitled to purchase any securities of the Company other than shares of 
     Common Stock, thereafter the number of such other securities so 
     purchasable upon exercise of the Warrant and the Exercise Price of such 
     securities shall be subject to adjustment from time to time in a manner 
     and on terms as nearly equivalent as practicable to the provisions with 
     respect to the Warrant Shares contained in this Section 9.

          (i)  Upon the expiration of any rights, options, warrants or 
     conversion privileges which caused an adjustment under this Section 9.1, 
     if such shall not have been exercised, the number of Warrant Shares 
     purchasable upon exercise of the Warrants and the Exercise Price, to the 
     extent the Warrants have not then been exercised, shall, upon such 
     expiration, be readjusted and shall thereafter be such as they would 
     have been had they been originally adjusted (or had the original 
     adjustment not been required, as the case may be) on the basis of (A) 
     the fact that the only shares of Common Stock so issued were the shares 
     of Common Stock, if any, actually issued or sold upon the exercise of 
     such rights, options, warrants or conversion rights and (B) the fact 
     that such shares of Common Stock, if any, were issued or sold for the 
     consideration actually received by the Company upon such exercise plus 
     the consideration, if any, actually received by the Company for the 
     issuance, sale or grant of all such rights, options, warrants or 
     conversion rights whether or not exercised; PROVIDED, HOWEVER, that no 
     such readjustment shall have the effect of increasing the Exercise Price 
     by an amount in excess of the amount of the adjustment initially made in 
     respect of the issuance, sale or grant of such rights, options, warrants 
     or conversion privileges.

     9.2  PRESERVATION OF PURCHASE RIGHTS UPON RECLASSIFICATION, CONSOLIDATION, 
ETC.  In case of any consolidation of the Company with or merger of the Company
into another corporation or in case of any sale or reconveyance to another
corporation of the property, assets or business of the Company as an entirety or
substantially as an entirety, the Company or such successor or

                                       10
<PAGE>

purchasing corporation, as the case may be, shall provide that the holder 
shall have the right thereafter upon payment of the Exercise Price in effect 
immediately prior to such action to purchase upon exercise of the Warrant the 
kind and amount of shares and other securities and property which he would 
have owned or have been entitled to receive after the happening of such 
consolidation, merger, sale or conveyance had the Warrant been exercised 
immediately prior to such action.  Such agreement shall provide for 
adjustments, which shall be as nearly equivalent as may be practicable to the 
adjustments provided for in this Section 9.  The provisions of this 
Subsection 9.2 shall similarly apply to successive consolidations, mergers, 
sales or conveyances.

     9.3  PAR VALUE OF COMMON STOCK.  Before taking any action which would 
cause an adjustment reducing the Exercise Price below the then par value of 
the shares of Common Stock issuable upon exercise of the Warrant, the Company 
will take any corporate action which may, in the opinion of its counsel, be 
necessary in order that the Company may validly and legally issue fully paid 
and non-assessable shares of Common Stock at such adjusted Warrant Price.

     9.4  STATEMENT ON WARRANT CERTIFICATES.  Irrespective of any adjustments 
in the Exercise Price or the number of securities purchasable upon the 
exercise of the Warrant, the Warrant certificate or certificates theretofore 
or thereafter issued may continue to express the same price and number of 
securities as are stated in the similar Warrant certificates initially 
issuable pursuant to this Agreement.  However, the Company may at any time in 
its sole discretion (which shall be conclusive) make any change in the form 
of the Warrant certificate that it may deem appropriate and that does not 
affect the substance thereof, and any Warrant certificate thereafter issued, 
whether upon registration or transfer of, or in exchange or substitution for, 
an outstanding Warrant certificate, may be in the form so changed.

     9.5  PRIOR NOTICE TO WARRANT HOLDERS.  In the event that at any time 
prior to the expiration of the Warrant and prior to its exercise, any of the 
following events shall occur:

          1.   any action which would require an adjustment pursuant to 
Sections 9.1 or 9.2; or

          2.   a dissolution, liquidation or winding up of the Company (other 
than in connection with a consolidation, merger or sale of its property, 
assets and business, as an entirety) shall be proposed;

then, in any such event, the Company shall cause at least twenty (20) days' 
prior written notice to be mailed to each Warrant

                                       11
<PAGE>

Holder at the address of such holder shown on the books of the Company.  The 
notice shall also specify the date on which the books of the Company shall 
close or a record be taken for such stock dividend, distribution or 
subscription rights, or the date on which such reclassification, 
reorganization, consolidation, merger, sale, transfer, disposition, 
liquidation, dissolution, winding up, or dividend, as the case may be, shall 
take place, and the date of participation therein by the holders of shares of 
Common Stock if any such date is to be fixed, and shall also set forth such 
facts with respect thereto as shall be reasonably necessary to indicate the 
effect of such action on the rights of the Warrant Holder.

     9.6  DISPUTES.  In the event that there is any dispute as to the 
computation of the Exercise Price or the number of shares of Common Stock 
required to be issued upon the exercise of the Warrants, the Company will 
retain an independent and nationally recognized accounting firm to conduct an 
audit of the computations pursuant to the terms hereof involved in such 
dispute, including the financial statements or other information upon which 
such computations were based.  The determination of such nationally 
recognized accounting firm shall, in the absence of manifest error, be 
binding.  If there shall be a dispute as to the selection of such nationally 
recognized accounting firm, such firm shall be appointed by the American 
Institute of Certified Public Accountants ("AICPA") if willing, otherwise the 
American Arbitration Association ("AAA").  If the Exercise Price or number of 
shares of Common Stock as determined by such accounting firm is one percent 
or more higher or lower than the calculations thereof computed by the 
Company, the expenses of such accounting firm and, if any, off AICPA and AAA, 
shall be borne completely by the Company.  In all other cases, they shall be 
borne by the complaining Warrant Holders, as applicable.

     9.5  CURRENT MARKET PRICE.  For the purpose of this Section 9, the term 
"Current Market Price" shall mean (i) if the Common Stock is traded in the 
over-the-counter market or on the National Association of Securities Dealers, 
Inc. Automated Quotations System ("NASDAQ"), the average per share closing 
bid prices of the Common Stock on the 20 consecutive trading days immediately 
preceding the date in question, as reported by NASDAQ or an equivalent 
generally accepted reporting service, or (ii) if the Common Stock is traded 
on a national securities exchange, the average for the 20 consecutive trading 
days immediately preceding the date in question of the daily per share 
closing prices of the Common Stock on the principal stock exchange on which 
it is listed, as the case may be.  The closing price referred to in clause 
(ii) above shall be the last reported sales price or in case no such reported 
sale takes place on such day, the average of the reported closing bid and 
asked prices, in either case on the national securities exchange on which the 
Common Stock is then listed.

     13.  SEVERABILITY.

          If any provision of this Agreement shall be held, declared or 
pronounced void, voidable, invalid, unenforceable, or inoperative for any 
reason by any court of competent jurisdiction, government authority or

adversely any other provision of this Agreement, which shall otherwise remain 
in full force and effect and be enforced in accordance with its terms, and

or admitted to unlisted trading privileges on such exchange, the price of the 
Common Stock to be determined during any applicable twenty (20) day trading 
period shall be the last reported sale price of the Common Stock on such 
exchange; or

     (b)  not quoted on the Bulletin Board listed or admitted to unlisted

                                    EXHIBIT A

          The securities represented hereby have not been registered under 
     the Securities Act of 1933, as amended, or any state securities laws and 
     neither the securities nor any interest therein may be offered, sold, 
     transferred, pledged or otherwise disposed of except pursuant to an 
     effective registration statement under such Act and such laws or an 
     exemption from registration under such Act and such laws which, in the 
     opinion of counsel for the holder, which counsel and opinion are 
     reasonably satisfactory to counsel for this corporation, is available.

                         SERIES A WARRANT CERTIFICATE 

                                 SERACARE, INC.

Warrant No. WA-1                                           No. of A Warrants: 2

     This certifies that, for value received and subject to the terms and
conditions set forth herein, 3 or his registered assign (the "Warrant Holder")
is the registered holder of 2 Series A Warrants.

     1.   EXERCISE.  The warrants evidenced hereby ("Series A Warrants"), as 
they may be adjusted from time to time, may be exercised at a price of $2.75 
per Warrant to acquire one (1) share of the common stock of SeraCare, Inc. 
which is with par value of $0.001 (the "Common Stock" and the "Company," 
respectively). (The Common Stock acquirable upon exercise hereof is referred 
to herein as "Warrant Stock.")  If, at the time of any exercise of a Series A 
Warrant, the Shares deliverable upon exercise of such Warrant shall not be 
registered under the Securities Act, the Company may require, as a condition 
of allowing such exercise, that the holder or transferee of such Warrant 
furnish to the Company an opinion of counsel of recognized standing in 
securities law to the effect that such exercise may be made without 
registration under the Securities Act; provided that, the exercise of the 
Warrant shall at all times be within the control of such holder or 
transferee, as the case may be, and, if required by the Company, accompanied 
by a written representation (i) that the shares being acquired by the 
exercise of the Warrant are being purchased for investment and not for 
distribution, (ii) acknowledging that such shares have not been registered 
under the Securities Act of 1933, as amended (the "1933 Act"), and (iii) 
agreeing that such shares may not be sold or transferred unless there is an 
effective Registration Statement for them under the 1933 Act, or in the 
opinion of counsel to the Company such sale or transfer is not in violation

                                     A-1
<PAGE>

of the 1933 Act.  No fractional shares may be acquired upon exercise hereof.

     2.   TERM OF WARRANT.  This Series A Warrant may be exercised at any 
time and from time to time in whole or in part commencing immediately upon 
issuance and terminating on the earlier of (i) the date three years after 
effectiveness of the Initial Registration Statement (as defined in the 
Warrant Agreement), provided, however, that (x) if the Common Stock 
underlying the Warrants is not subject to an effective registration for an 
aggregate of 600 days within three years after the final closing of the 
Private Offering, then the remaining exercise period under this clause (i) 
shall be tolled until the Common Stock underlying this Series A Warrant shall 
have been subject to an effective registration for an aggregate of 600 days 
and (y) in no event shall this Series A Warrant terminate under this clause 
(i) unless a registration statement covering the Warrant Stock shall have 
then been in effect for 45 days prior to such termination, and (ii) six years 
from the date of issuance, unless extended by a majority vote of the Board of 
Directors for such length of time as they, in their sole discretion, deem 
reasonable and necessary.

     3.   ADJUSTMENT OF EXERCISE PRICE.  The number of shares purchasable 
upon exercise of this Series A Warrant is subject to adjustment in accordance 
with the Series A Warrant Agreement.

     4.   REDEMPTION.    These Warrants may be redeemed upon 30 days advance 
notice upon conditions set forth in the Series A Warrant Agreement.

     5.   RESERVATION OF COMMON STOCK.  The Company agrees that the number of 
shares of Common Stock sufficient to provide for the exercise of the A 
Warrants upon the basis set forth herein will at all times during the term of 
this Series A Warrant be reserved for the exercise hereof.

     6.   MANNER OF EXERCISE.  Exercise may be made of all or any part of the 
A Warrants by surrendering this certificate, with the purchase form to be 
provided by the Company, duly executed by the Warrant Holder or by the 
Warrant Holder's duly authorized attorney, plus payment of the exercise price 
therefor in cash at the office of the Company or its designated assign.

     7.   ISSUANCE OF COMMON STOCK UPON EXERCISE.  The Company, at its own 
expense, shall cause to be issued, within ten (10) days after exercise of 
this Series A Warrant, a certificate or certificates in the name or names 
requested by the Warrant Holder representing the number of shares of Common 
Stock to which the Warrant Holder is entitled upon such exercise.  All shares 
of Common Stock or other securities delivered upon the exercise of

                                     A-2
<PAGE>

this Series A Warrant shall be validly issued, fully paid and non-assessable.

     Irrespective of the date of issuance and delivery of any certificate 
representing the shares of Common Stock upon the exercise of this Series A 
Warrant, each person in whose name any such certificate is to be issued will 
for all purposes be deemed to have become the holder of record of the Common 
Stock acquired on the date on which a duly executed notice of exercise of 
this A Warrant and payment for the number of shares exercised are received by 
the Company.

     8.   REGISTRATION RIGHTS.  The Company will use its best efforts to
register the Warrant Stock prior to that date which is 270 days after the Final
Closing of the Private Offering and the Company agrees to use its best efforts
to maintain an effective Registration Statement during the term of the A
Warrants, as more fully set forth in the Warrant Agreement and the Registration
Rights Agreement governing the issuance and registration of the A Warrants and
Warrant Stock.

     9.   NO RIGHT AS STOCKHOLDER.  The Warrant Holder is not, by virtue of his
ownership of this Series A Warrant, entitled to any rights whatsoever as a
stockholder of the Company.

     10.  ASSIGNMENT.  This Series A Warrant may not be assigned without 
providing the Company an opinion satisfactory to its counsel that an 
exemption from registration for the transfer exists.

     11.  STATE LEGENDS.  Residents of Connecticut are advised of the 
following:

          THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER SECTION 36-485 OF
          THE CONNECTICUT UNIFORM SECURITIES ACT, CHAPTER 662 OF THE 
          CONNECTICUT GENERAL STATUTES, AND ARE SUBJECT TO RESTRICTIONS ON 
          TRANSFERABILITY AND SALE AND CANNOT BE RESOLD UNLESS THEY ARE

          SKY REGULATIONS.)

     12.  WARRANT AGREEMENT.  The actual terms and conditions of this Series A
Warrant are contained in a Warrant Agreement entered into by and between the

Ladies and Gentlemen:

     Enclosed for your records is a corrected page 5 from the Subscription 
Agreement in connection with your recent purchase of Units from SeraCare, 
Inc. Section 7 of the Subscription Agreement originally provided that Barry 
Plost and Jerry Burdick be appointed as your attorney-in-fact to execute the 
Registration Rights Agreement, but inadvertently failed to provide for the

documents provided to you. Section 7 of the Subscription Agreement has been 
revised to clarify that Barry Plost and Jerry Burdick may also execute the 
Series A Warrant Agreement as attorney-in-fact on your behalf.

     Please acknowledge your agreement to the foregoing by signing the 
enclosed copy of this letter and returning it in the enclosed self-addressed 
stamped envelope. If you have any questions, please feel free to call me at: 
(310) 771-7777.

Very Truly Yours,

         registered under the Securities Act of 1933, as amended, 
         or any state securities laws and neither the securities 
         nor any interest therein may be offered, sold, 
         transferred, pledged or otherwise disposed of except 
         pursuant to an effective registration statement under 
         such Act and such laws or an exemption from registration 
         under such Act and such laws which, in the opinion of

         reasonably satisfactory to counsel for this corporation, 
         is available.
          
                          SERIES A WARRANT AGREEMENT

     This Agreement (the "AGREEMENT") dated October 23, 1996 between SeraCare,
Inc., a Delaware corporation (the "COMPANY" and the "WARRANT AGENT") and those
individuals and entities purchasing the "Units" in a private offering by the
Company,
     
                             W I T N E S S E T H:

     WHEREAS, the Company proposes to privately offer (the "PRIVATE OFFERING")
up to 200 Units (subject to an option for an additional 80 Units) to individuals
and entities, each Unit to consist of five-thousand shares of the Company's
common stock (the "Common Stock"), and two-thousand five-hundred warrants to
purchase an additional share of Common Stock, such right to be evidenced by a
"Series A Warrant", with the Series A Warrants being collectively referred to
herein as the "Series A Warrants" or "Warrants";
     
     WHEREAS, exclusive of the aforesaid option, in connection with the proposed
Private Offering, the Company anticipates its issuance of up to 500,000 Series A
Warrants to purchase up to 500,000 shares of Common Stock (the shares received
upon exercise of the Series A Warrants are referred to herein as the "WARRANT
SHARES");
     
     WHEREAS, the Company desires to provide for the issuance of certificates
representing the Series A Warrants (a "Series A Warrant Certificate" or
collectively the "Series A Warrant Certificates");
     
     WHEREAS, the Company desires to act as its own warrant agent in connection
with the issuance, registration, transfer and exchange of Series A Warrant
Certificates and the exercise of the Series A Warrants;
     
     NOW, THEREFORE, in consideration of the above and foregoing premises and
the mutual promises and agreements hereinafter set forth, it is agreed that:

                                       1

<PAGE>

     1.   SERIES A WARRANT CERTIFICATES.
     
          (a)  Each Series A Warrant shall entitle the holder (the 
"Registered Holder," or, in the aggregate, the "Registered Holders") in whose 
name the certificate shall be registered on the books maintained by the 
Company to purchase one (1) share of Common Stock on the exercise thereof, 
subject to modification and adjustment as provided in Section 9 hereof.  
Series A Warrant Certificates shall be executed by the Company's Chairman, 
President or Senior Vice President and attested to by the Company's 
Secretary.  The Series A Warrant Certificates shall be immediately detachable 
from certificates representing shares of Common Stock and shall be 
distributed to the purchasers thereof concurrently with each closing of the 
Private Offering.

           (b)  Subject to the provisions of Sections 3, 5, and 7 hereof, the 
Company shall deliver Series A Warrant Certificates in required whole number 
denominations to Registered Holders in connection with any transfer or 
exchange permitted under this Agreement.  Except as provided in Section 7 
hereof, no certificates shall be issued except (i) certificates initially 
issued hereunder, (ii) certificates issued on or after their initial issuance 
date upon the exercise of any Warrant to evidence the unexercised Series A 
Warrants held by the exercising Registered Holder and (iii) Series A Warrant 
certificates issued after their initial issuance date, upon any transfer or 
exchange of certificates or replacements of lost or mutilated certificates.

     2.   FORM AND EXECUTION OF SERIES A WARRANT CERTIFICATES.
     
           (a)  The Series A Warrant certificates shall be dated the date of 
the original issuance of the Series A Warrants, whether on initial transfer 
or exchange or in lieu of mutilated, lost, stolen or destroyed certificates.  
The form of Series A Warrant certificate is annexed hereto as "Exhibit A."

           (b)  Each Series A Warrant certificate shall be numbered serially 
bearing "WA" as an initial designation, and subsequent to this designation 
the serial numbering of the Series A Warrant certificate should match, to the 
extent possible, the serial numbering of the Common Stock initially attached 
thereto.

           (c)  The Series A Warrant Certificates shall be manually signed on 
behalf of the Company by a proper officer thereof and shall not be valid for 
any purpose unless so signed. In the event any officer of the Company who 
executed certificates shall cease to be an officer of the Company such 
certificates may be issued and delivered by the Company or transferred by the 
Registered Holders with the same force and effect as though the person who 
signed such certificate had not ceased to be an

                                       2

<PAGE>

officer of the Company; and any certificate signed on behalf of the Company 
by any person, who at the actual date of the execution of such certificate 
was a proper officer of the Company, shall be proper notwithstanding that at 
the date of execution of this Agreement any such person was not such an 
officer.

     3.   EXERCISE.
     
           (a)  Subject to the provisions of Sections 5 and 9 hereof, the 
Series A Warrants, as they may be adjusted as set forth herein, may be 
exercised at a price (the "WARRANT EXERCISE PRICE") of $2.75 per share of 
Common Stock subject to adjustment, in whole or in part at any time during 
the period (the "WARRANT EXERCISE PERIOD") commencing on the date of issuance 
of the Series A Warrant and terminating on the earlier of (i) the date three 
years after effectiveness of the Initial Registration Statement, provided, 
however, that (x) if the Common Stock underlying the Warrants is not subject 
to an effective registration for an aggregate of 600 days within three years 
after the final closing of the Private Offering, then the remaining exercise 
period under this clause (i) shall be tolled until the Common Stock 
underlying the Warrants shall have been subject to an effective registration 
for an aggregate of 600 days and (y) in no event shall the Series A Warrants 
terminate under this clause (i) unless a registration statement covering the 
Warrant Shares shall have then been in effect for 45 days prior to such 
termination, and (ii) six years from the date of issuance (the "WARRANT 
EXPIRATION DATE"), unless extended by a majority vote of the Board of 
Directors for such length of time as they, in their sole discretion, deem 
reasonable and necessary.

           (b)  Each Series A Warrant shall be deemed to have been exercised 
immediately prior to the close of business on the date (each, an "EXERCISE 
DATE") of the surrender to the Company for exercise of the Series A Warrant 
certificate.  The exercise form shall be executed by the Warrant Holder 
thereof or his attorney duly authorized in writing and shall be delivered 
together with payment to the Company at its corporate offices located at 1875 
Century Park East, Suite 2130, Los Angeles, CA. 90067 (the "CORPORATE 
OFFICE"), or at any such other office or agency as the Company may designate, 
in cash or by official bank or certified check, of an amount equal to the 
aggregate Exercise Price, in lawful money of the United States of America.

           (c)  Unless Warrant Shares may not be issued as provided herein, 
the person entitled to receive the number of Warrant Shares deliverable on 
exercise shall be treated for all purposes as the holder of such Warrant 
Shares as of the close of business on the Exercise Date.  The Company shall 
not be obligated to issue any fractional share interest in Warrant Shares 
issuable or deliverable on the exercise of any Series A

                                       3

<PAGE>

Warrant or scrip or cash therefore and such fractional shares shall be of no
value whatsoever.

           (d)  Within ten days after the Exercise Date and in any event 
prior to the Warrant Expiration Date, the Company, at its own expense, shall 
cause to be issued and delivered to the person or persons entitled to receive 
the same, a certificate or certificates in the name requested by the 
Registered Holder for the number of Warrant Shares deliverable on such 
exercise.  No adjustment shall be made in respect of cash dividends on 
Warrant Shares delivered on exercise of any Series A Warrant.  All shares of 
Common Stock delivered upon the exercise of the Series A Warrants shall be 
validly issued, fully paid and non-assessable. Any Series A Warrants 
redelivered to the Registered Holder in the event of the exercise of less 
than all of the Series A Warrants pertaining to a surrendered Series A 
Warrant certificate, shall be validly issued, fully paid and non-assessable.

           (e)  The Series A Warrants shall not entitle the holder thereof to 
any of the rights of shareholders or to any dividend declared on the Common 
Stock unless such holder or holders shall have exercised the Series A 
Warrants prior to the record date fixed by the Board of Directors for the 
determination of holders of Common Stock entitled to such dividends or other 
rights.

     4.   REGISTRATION RIGHTS.
     
          The holders of Series A Warrants shall have the registration rights 
under the Securities Act of 1933, as amended (the "ACT"), and the rules and 
regulations promulgated thereunder by the Securities and Exchange Commission 
(the "COMMISSION"), provided for in that certain Registration Rights 
Agreement executed by the Company and the A Warrant holders on even date 
herewith (the "REGISTRATION RIGHTS AGREEMENT").  The Registration Rights 
Agreement is incorporated herein by this reference in its entirety as if 
fully set forth herein.
          
     5.   RESERVATION OF SHARES AND PAYMENT OF TAXES.
     
           (a)  The Company covenants that it shall at all times reserve and 
have available from its authorized Common Stock such number of shares as 
shall then be issuable on the exercise of all outstanding Series A Warrants.  
The Company covenants that all Warrant Shares shall be duly and validly 
issued, fully paid and non-assessable, and shall be free from all taxes, 
liens and charges with respect to the issuance thereof.

           (b)  The Company shall pay all documentary, stamp or similar taxes 
and other government charges that may be imposed with respect of the issuance 
of the Series A Warrants, and/or the issuance of any Common Stock 
constituting the Warrant Shares on the exercise of the Series A Warrants.  In 
the event the Warrant

                                       4

<PAGE>

Shares are to be delivered in a name other than the name of the initial 
Registered Holder of the certificate, no such delivery shall be made unless 
the person requesting the same has paid to the Company the amount of any such 
taxes, charges, or transfer fees incident thereto.

     6.   REGISTRATION OF TRANSFER.
     
           (a)  The Series A Warrant certificates may, subject to provisions 
of the Federal Securities Laws and any applicable state securities laws, be 
transferred in whole or in part Certificates to be transferred shall be 
surrendered to the Company at its Corporate Office.  The Company shall 
execute, issue and deliver in exchange therefor the Series A Warrant 
certificates in the names and amounts that the holder making the transfer 
shall have designated in writing.  The Company shall keep transfer books at 
its Corporate Office which shall register certificates and the transfer 
thereof.  On due presentment for registration of transfer of any certificate 
at the Corporate Office, the Company shall execute, issue and deliver to the 
transferee or transferees a new certificate or certificates representing an 
equal aggregate number of securities.  All such certificates shall be duly 
endorsed or be accompanied by a written instrument or instruments of transfer 
in form reasonably satisfactory to the Company.  The established transfer fee 
for any registration of transfer of certificates shall be paid by the Warrant 
Holder or the person presenting the certificate for transfer.

           (b)  Prior to due presentment for registration or transfer 
thereof, the Company may treat the Registered Holder of any certificate as 
the absolute owner thereof (notwithstanding any notations of ownership or 
writing thereon made by anyone), and the parties hereto shall not be affected 
by any notice to the contrary.

     7.   LOSS OR MUTILATION.
     
          On receipt by the Company of evidence satisfactory as to the 
ownership of and the loss, theft, destruction or mutilation of any Series A 
Warrant certificate, the Company shall execute and deliver in lieu thereof a 
new certificate representing an equal number of Series A Warrants.  In the 
case of loss, theft or destruction of any certificate, the individual 
requesting reissuance of a new certificate shall be required to indemnify the 
Company and, at the request of the Company, to post an open-penalty insurance 
or indemnity bond.  In the event a certificate is mutilated, such certificate 
shall be surrendered and canceled by the Company prior to delivery of a new 
certificate. Applicants for a new certificate shall also comply with such 
other regulations and pay such other reasonable charges as the Company may 
prescribe.

                                       5

<PAGE>

     8.   REDEMPTION OPTION.
     
     The Company shall have the right and option, upon 30 days' prior written 
notice to each Registered Holder, to, at any time thereafter, call, redeem 
and acquire all or a portion of the Series A Warrants which remain 
outstanding and unexercised at the date fixed for redemption (the "Series A 
Warrant Redemption Date") at a price of $.01 per Series A Warrant if, and 
only if, the average of the closing bid and closing asked price per share of 
the Common Stock for each of the 20 consecutive trading days immediately 
prior to the mailing of said notification, and for each day thereafter until 
the Series A Warrant Redemption Date shall have exceeded 133.3% of the then 
Exercise Price.  The Series A Warrant Holders shall in all events have the 
right during the period immediately following the date of such notice and 
prior to the Series A Warrant Redemption Date to exercise the Series A 
Warrants in accordance with the provisions of Section 3 hereof.
     
     No call for redemption and no redemption of the Series A Warrants shall 
be made unless the Company shall have an effective registration statement 
under the Act on file during such period from the date of mailing of the 
notice of redemption through the applicable redemption date with the 
Commission and all applicable state securities commissions relating to the 
Common Stock and the Warrant Shares, except that this obligation, as it 
relates to the Warrant Shares or Common Stock, may be satisfied if such 
Warrant Shares or Common Stock, respectively, may be transferred publicly in 
accordance with Rule 144 or otherwise without registration under the Act.  In 
the event that any Series A Warrants are exercised following notice but prior 
to redemption, this call option shall be deemed not to have been exercised by 
the Company as to the Series A Warrants so exercised.
     
     The redemption notice shall require each Warrant Holder to surrender the
Series A Warrants on or before the Redemption Date in accordance with the
provisions of the redemption notice.  In the event the Series A Warrant
Certificates representing the Series A Warrants called for redemption have not
been surrendered for redemption and cancellation on the applicable redemption
date, such Series A Warrants shall be deemed to have expired and all rights of
the holders of such unsurrendered Series A Warrants shall cease and terminate,
other than the right to receive the redemption price without interest; provided,
however, that such right to receive the redemption price shall itself expire one
year from the Series A Warrant Redemption Date if no claim is made therefor
prior to such date.

     9.   ADJUSTMENT OF INITIAL EXERCISE
          PRICE AND NUMBER OF SHARES PURCHASABLE.
     
          For purposes hereof, the term "INITIAL EXERCISE PRICE" shall mean, 
with respect to the A Warrants, $2.75.  The Initial Exercise Price and the 
number of shares of Common Stock purchasable pursuant to the A Warrants shall 
be subject to adjustment from time to time as hereinafter set forth in this 
Section 9.
          
          9.1  ADJUSTMENTS.  The number of Warrant Shares purchasable upon the
exercise of the Warrants and the Exercise Price shall be subject to adjustment
as follows:

          (a) In case the Company shall (i) pay a dividend in shares of Common
    Stock or make a distribution in shares of Common Stock, (ii) subdivide its
    outstanding shares of Common Stock, (iii) combine its outstanding shares of
    Common Stock into a smaller number of shares of Common Stock or (iv) issue
    by reclassification of its Common Stock other securities of the Company, the
    number of Warrant Shares purchasable upon exercise of the Warrants
    immediately prior thereto shall be adjusted so that the holder shall be
    entitled to receive the kind and number of Common Stock or other securities
    of the Company which it would have owned or would have been entitled to
    receive after the happening of any of the events described above, had the
    Warrants been exercised immediately prior to the happening of such event or
    any record date with respect thereto. Any adjustment made pursuant to this
    Paragraph (a) shall become effective immediately after the effective date of
    such event retroactive to the record date, if any, for such event.
 
          (b) In case the Company shall issue rights, options, warrants or
    convertible securities to all or substantially all holders of its Common
    Stock, without any consideration, entitling them to subscribe for or to
    purchase shares of Common Stock at a price per share which is lower at the
    record date mentioned below than the then Current Market Price (as defined
    below), the number of Warrant Shares thereafter purchasable upon the
    exercise of a Warrant shall be determined by multiplying the number of
    Warrant Shares theretofore purchasable upon exercise of each Warrant by a
    fraction, of which the numerator shall be (1) the number of shares of Common
    Stock outstanding immediately prior to the issuance of such rights, options
    or warrants plus (2) the number of additional shares of Common Stock offered
    for subscription or purchase, and of which the denominator shall be (x) the
    number of shares of Common Stock outstanding immediately prior to the
    issuance of such rights, options or warrants plus (y) the number of shares
    which the aggregate offering price of the total number of shares offered
    would
 
                                       7
<PAGE>
    purchase at the Current Market Price. Such adjustment shall be made whenever
    such rights, options or warrants are issued, and shall become effective
    immediately and retroactively after the record date for the determination of
    shareholders entitled to receive such rights, options or warrants.
 
          (c) In case the Company shall distribute to all or substantially all
    holders of its shares of Common Stock evidences of its indebtedness or
    assets (excluding cash dividends or distributions out of earnings) or
    rights, options, warrants or convertible securities containing the right to
    subscribe for or purchase shares of Common Stock (excluding those referred
    to in paragraph (b) above), then, in each case, the number of Warrant Shares
    thereafter purchasable upon the exercise of the Warrants shall be determined
    by multiplying the number of Warrant Shares theretofore purchasable upon
    exercise of the Warrants by a fraction, of which the numerator shall be the
    then Current Market Price on the date of such distribution, and of which the
    denominator shall be such Current Market Price on such date minus the then
    fair value of the portion of the assets or evidence of indebtedness so
    distributed or of such subscription rights, options or warrants applicable
    to one share. Such adjustment shall be made whenever any such distribution
    is made and shall become effective on the date of distribution retroactive
    to the record date for the determination of shareholders entitled to receive
    such distribution.
 
          (d) No adjustment in the number of Warrant Shares purchasable 
    hereunder shall be required unless such adjustment would require an 
    increase or decrease of at least one percent (1%) in the number of Shares
    then purchasable upon the exercise of a Warrant; PROVIDED, HOWEVER, that any
    adjustments which by reason of this Paragraph (d) are not required to be
    made immediately shall be carried forward and taken into account in any
    subsequent adjustment.
 
          (e) Whenever the number of Warrant Shares purchasable upon the 
    exercise of a Warrant is adjusted as herein provided, the Exercise Price 
    payable upon exercise of a Warrant shall be adjusted by multiplying such 
    Exercise Price immediately prior to such adjustment by a fraction, of which
    the numerator shall be the number of Warrant Shares purchasable upon the 
    exercise of a Warrant immediately prior to such adjustment, and of which 
    the denominator shall be the number of Shares so purchasable immediately 
    thereafter.
 
          (f) The Exercise Price of the Series A Warrants shall be automatically
    and permanently reduced by $.10 per share each if (i) the Initial
    Registration Statement (as defined
 
                                       8

<PAGE>

    in the Registration Rights Agreement) has not become effective on or prior
    to that date which is 270 days from the Final Closing Date, (ii) the
    Commission shall have issued a stop order suspending the effectiveness of
    the Initial Registration Statement and the number of days stop orders have
    been in effect, together with the number of days a notice under Section
    4.1(d) of the Registration Rights Agreement has been issued or required to
    be issued, exceeds 180 days, or (iii) (A) the Company for the third time,
    notifies or is required to notify the holders of the Warrants pursuant to
    Section 4.1(d) of the Registration Rights Agreement, or (B) a notice under
    such Section 4.1(d) is effective or required to be effective at a time when
    the aggregate number of days for which all such notices issued or required
    to be issued pursuant to such Section 4.1(d) have been, or were required to
    be, in effect, exceeds 180 days (270 days from the Final Closing Date in the
    case of clause (i), or the date the third notice is sent or required to be
    sent or the date on which the 180-day limit is exceeded in the case of
    clause (ii) or (iii), is each referred to herein as an "Event Date").
    Additionally, the Exercise Price of each Series A Warrant then outstanding
    shall be subject to further downward adjustment in the amount of $.10 each
    on the same day of each month following the initial Event Date (or, if there
    is no numerically corresponding day in any such subsequent month, then on
    the last day of such applicable subsequent month) until the Registration
    Statement becomes effective; PROVIDED, HOWEVER, that such adjustments will,
    in each case, cease to accrue on the date which (x) the Initial Registration
    Statement is declared effective, with respect to the adjustments for failure
    to be declared effective by that date which is 270 days from the Final
    Closing Date, (y) the Initial Registration Statement is no longer subject to
    an order suspending the effectiveness thereof, with respect to adjustments
    for the failure to remain effective or (z) a notice issued, or required to
    be issued, pursuant to Section 5.1(d) is no longer effective or required to
    be effective, with respect to adjustments payable pursuant to clause (iii)
    above. In no event shall the Series A Warrant exercise price be adjusted
    below $1.50 solely due to this Section 9.1(f).
 
          (g) Whenever the number of Warrant Shares purchasable upon the 
    exercise of a Warrant or the Exercise Price is adjusted as herein provided,
    the Company shall cause to be promptly mailed to the holder by first class
    mail, postage prepaid, notice of such adjustment or adjustments and a 
    certificate of a firm of independent public accountants selected by the 
    Board of Directors of the Company (who may be the regular accountants 
    employed by the Company) setting forth the number of Warrant Shares 
    purchasable upon the

                                       9

<PAGE>

    exercise of a Warrant and the Exercise Price after such adjustment, a brief
    statement of the facts requiring such adjustment and the computation by
    which such adjustment was made.
 
          (h) For the purpose of this Subsection 9.1, the term "Common Stock"
    shall mean (i) the class of stock designated as the Common Stock of the
    Company at the date of this Agreement or (ii) any other class of stock
    resulting from successive changes or reclassifications of such Common Stock.
    In the event that at any time, as a result of an adjustment made pursuant to
    this Section 9, the holder shall become entitled to purchase any securities
    of the Company other than shares of Common Stock, thereafter the number of
    such other securities so purchasable upon exercise of the Warrant and the
    Exercise Price of such securities shall be subject to adjustment from time
    to time in a manner and on terms as nearly equivalent as practicable to the
    provisions with respect to the Warrant Shares contained in this Section 9.
 
          (i) Upon the expiration of any rights, options, warrants or conversion
    privileges which caused an adjustment under this Section 9.1, if such shall
    not have been exercised, the number of Warrant Shares purchasable upon
    exercise of the Warrants and the Exercise Price, to the extent the Warrants
    have not then been exercised, shall, upon such expiration, be readjusted and
    shall thereafter be such as they would have been had they been originally
    adjusted (or had the original adjustment not been required, as the case may
    be) on the basis of (A) the fact that the only shares of Common Stock so
    issued were the shares of Common Stock, if any, actually issued or sold upon
    the exercise of such rights, options, warrants or conversion rights and (B)
    the fact that such shares of Common Stock, if any, were issued or sold for
    the consideration actually received by the Company upon such exercise plus
    the consideration, if any, actually received by the Company for the
    issuance, sale or grant of all such rights, options, warrants or conversion
    rights whether or not exercised; PROVIDED, HOWEVER, that no such
    readjustment shall have the effect of increasing the Exercise Price by an
    amount in excess of the amount of the adjustment initially made in respect
    of the issuance, sale or grant of such rights, options, warrants or
    conversion privileges.
     
    9.2  PRESERVATION OF PURCHASE RIGHTS UPON RECLASSIFICATION. CONSOLIDATION 
ETC.  In case of any consolidation of the Company with or merger of the Company
into another corporation or in case of any sale or reconveyance to another
corporation of the property, assets or business of the Company as an entirety or
substantially as an entirety, the Company or such successor or


                                     10

<PAGE>

purchasing corporation, as the case may be, shall provide that the holder shall
have the right thereafter upon payment of the Exercise Price in effect
immediately prior to such action to purchase upon exercise of the Warrant the
kind and amount of shares and other securities and property which he would have
owned or have been entitled to receive after the happening of such
consolidation, merger, sale or conveyance had the Warrant been exercised
immediately prior to such action.  Such agreement shall provide for adjustments,
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 9.  The provisions of this Subsection 9.2 shall
similarly apply to successive consolidations, mergers, sales or conveyances.

     9.3  PAR VALUE OF COMMON STOCK.  Before taking any action which would cause
an adjustment reducing the Exercise Price below the then par value of the shares
of Common Stock issuable upon exercise of the Warrant, the Company will take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may validly and legally issue fully paid and non-assessable
shares of Common Stock at such adjusted Warrant Price.
     
     9.4  STATEMENT ON WARRANT CERTIFICATES.  Irrespective of any adjustments in
the Exercise Price or the number of securities purchasable upon the exercise of
the Warrant, the Warrant certificate or certificates theretofore or thereafter
issued may continue to express the same price and number of securities as are
stated in the similar Warrant certificates initially issuable pursuant to this
Agreement.  However, the Company may at any time in its sole discretion (which
shall be conclusive) make any change in the form of the Warrant certificate that
it may deem appropriate and that does not affect the substance thereof; and any
Warrant certificate thereafter issued, whether upon registration or transfer of,
or in exchange or substitution for, an outstanding Warrant certificate, may be
in the form so changed.
     
     9.5 PRIOR NOTICE TO WARRANT HOLDERS.  In the event that at any time prior
to the expiration of the Warrant and prior to its exercise, any of the following
events shall occur:
     
          1.  any action which would require an adjustment pursuant to 
              Sections 9.1 or 9.2; or
          
          2.  a dissolution, liquidation or winding up of the Company (other
              than in connection with a consolidation, merger or sale of its 
              property, assets and business, as an entirety) shall be proposed;
          
then, in any such event, the Company shall cause at least twenty (20) days'
prior written notice to be mailed to each Warrant

                                     11

<PAGE>

Holder at the address of such holder shown on the books of the Company.  The
notice shall also specify the date on which the books of the Company shall close
or a record be taken for such stock dividend, distribution or subscription
rights, or the date on which such reclassification, reorganization,
consolidation, merger, sale, transfer, disposition, liquidation, dissolution,
winding up, or dividend, as the case may be, shall take place, and the date of
participation therein by the holders of shares of Common Stock if any such date
is to be fixed, and shall also set forth such facts with respect thereto as
shall be reasonably necessary to indicate the effect of such action on the
rights of the Warrant Holder.

          9.6 DISPUTES.  In the event that there is any dispute as to the
computation of the Exercise Price or the number of shares of Common Stock
required to be issued upon the exercise of the Warrants, the Company will retain
an independent and nationally recognized accounting firm to conduct an audit of
the computations pursuant to the terms hereof involved in such dispute,
including the financial statements or other information upon which such
computations were based.  The determination of such nationally recognized
accounting firm shall, in the absence of manifest error, be binding.  If there
shall be a dispute as to the selection of such nationally recognized accounting
firm, such firm shall be appointed by the American Institute of Certified Public
Accountants ("AICPA") if willing, otherwise the American Arbitration Association
("AAA").  If the Exercise Price or number of shares of Common Stock as
determined by such accounting firm is one percent or more higher or lower than
the calculations thereof computed by the Company, the expenses of such
accounting firm and, if any, off AICPA and AAA, shall be borne completely by the
Company.  In all other cases, they shall be borne by the complaining Warrant
Holders, as applicable.
          
          9.5 CURRENT MARKET PRICE.  For the purpose of this Section 9, the term
"Current Market Price" shall mean (i) if the Common Stock is traded in the over-
the-counter market or on the National Association of Securities Dealers, Inc.
Automated Quotations System ("NASDAQ"), the average per share closing bid prices
of the Common Stock on the 20 consecutive trading days immediately preceding the
date in question, as reported by NASDAQ or an equivalent generally accepted
reporting service, or (ii) if the Common Stock is traded on a national
securities exchange, the average for the 20 consecutive trading days immediately
preceding the date in question of the daily per share closing prices of the
Common Stock on the principal stock exchange on which it is listed, as the case
may be.  The closing price referred to in clause (ii) above shall be the last
reported sales price or in case no such reported sale takes place on such day,
the average of the reported closing bid and asked prices, in either case on the
national securities exchange on which the Common Stock is then listed.

                                  EXHIBIT A

         The securities represented hereby have not been 
         registered under the Securities Act of 1933, as amended, 
         or any state securities laws and neither the securities 
         nor any interest therein may be offered, sold, 
         transferred, pledged or otherwise disposed of except 
         pursuant to an effective registration statement under 
         such Act and such laws or an exemption from registration 
         under such Act and such laws which, in the opinion of 
         counsel for the holder, which counsel and opinion are 
         reasonably satisfactory to counsel for this corporation, 
         is available.

                        SERIES A WARRANT CERTIFICATE
                               SERACARE, INC.

Warrant No. WA-1                                           No. of A Warrants: 2

     This certifies that, for value received and subject to the terms and
conditions set forth herein, 3 or his registered assign (the "Warrant Holder")
is the registered holder of 2 Series A Warrants.
     
     1.   EXERCISE.  The warrants evidenced hereby ("Series A Warrants"), as
they may be adjusted from time to time, may be exercised at a price of $2.75 per
Warrant to acquire one (1) share of the common stock of SeraCare, Inc. which is
with par value of $0.001 (the "Common Stock" and the "Company," respectively). 
(The Common Stock acquirable upon exercise hereof is referred to herein as
"Warrant Stock.")  If, at the time of any exercise of a Series A Warrant, the
Shares deliverable upon exercise of such Warrant shall not be registered under
the Securities Act, the Company may require, as a condition of allowing such
exercise, that the holder or transferee of such Warrant furnish to the Company
an opinion of counsel of recognized standing in securities law to the effect
that such exercise may be made without registration under the Securities Act;
provided that, the exercise of the Warrant shall at all times be within the
control of such holder or transferee, as the case may be, and, if required by
the Company, accompanied by a written representation (i) that the shares being
acquired by the exercise of the Warrant are being purchased for investment and
not for distribution, (ii) acknowledging that such shares have not been
registered under the Securities Act of 1933, as amended (the "1933 Act"), and
(iii) agreeing that such shares may not be sold or transferred unless there is
an effective Registration Statement for them under the 1933 Act, or in the
opinion of counsel to the Company such sale or transfer is not in violation

                                      A-1

<PAGE>

of the 1933 Act.  No fractional shares may be acquired upon exercise hereof.

     2.   TERM OF WARRANT.  This Series A Warrant may be exercised at any time
and from time to time in whole or in part commencing immediately upon issuance
and terminating on the earlier of (i) the date three years after effectiveness
of the Initial Registration Statement (as defined in the Warrant Agreement),
provided, however, that (x) if the Common Stock underlying the Warrants is not
subject to an effective registration for an aggregate of 600 days within three
years after the final closing of the Private Offering, then the remaining
exercise period under this clause (i) shall be tolled until the Common Stock
underlying this Series A Warrant shall have been subject to an effective
registration for an aggregate of 600 days and (y) in no event shall this Series
A Warrant terminate under this clause (i) unless a registration statement
covering the Warrant Stock shall have then been in effect for 45 days prior to
such termination, and (ii) six years from the date of issuance, unless extended
by a majority vote of the Board of Directors for such length of time as they, in
their sole discretion, deem reasonable and necessary.
     
     3.   ADJUSTMENT OF EXERCISE PRICE.  The number of shares purchasable upon
exercise of this Series A Warrant is subject to adjustment in accordance with
the Series A Warrant Agreement.
     
     4.   REDEMPTION.    These Warrants may be redeemed upon 30 days advance
notice upon conditions set forth in the Series A Warrant Agreement.
     
     5.   RESERVATION OF COMMON STOCK.  The Company agrees that the number of
shares of Common Stock sufficient to provide for the exercise of the A Warrants
upon the basis set forth herein will at all times during the term of this Series
A Warrant be reserved for the exercise hereof.
     
     6.   MANNER OF EXERCISE.  Exercise may be made of all or any part of the A
Warrants by surrendering this certificate, with the purchase form to be provided
by the Company, duly executed by the Warrant Holder or by the Warrant Holder's
duly authorized attorney, plus payment of the exercise price therefor in cash at
the office of the Company or its designated assign.
     
     7.   ISSUANCE OF COMMON STOCK UPON EXERCISE.  The Company, at its own
expense, shall cause to be issued, within ten (10) days after exercise of this
Series A Warrant, a certificate or certificates in the name or names requested
by the Warrant Holder representing the number of shares of Common Stock to which
the Warrant Holder is entitled upon such exercise.  All shares of Common Stock
or other securities delivered upon the exercise of

                                      A-2

<PAGE>

this Series A Warrant shall be validly issued, fully paid and non-assessable.

     Irrespective of the date of issuance and delivery of any certificate
representing the shares of Common Stock upon the exercise of this Series A
Warrant, each person in whose name any such certificate is to be issued will for
all purposes be deemed to have become the holder of record of the Common Stock
acquired on the date on which a duly executed notice of exercise of this A
Warrant and payment for the number of shares exercised are received by the
Company.
     
     8.   REGISTRATION RIGHTS.  The Company will use its best efforts to
register the Warrant Stock prior to that date which is 270 days after the Final
Closing of the Private Offering and the Company agrees to use its best efforts
to maintain an effective Registration Statement during the term of the A
Warrants, as more fully set forth in the Warrant Agreement and the Registration
Rights Agreement governing the issuance and registration of the A Warrants and
Warrant Stock.
     
     9.   NO RIGHT AS STOCKHOLDER.  The Warrant Holder is not, by virtue of his
ownership of this Series A Warrant, entitled to any rights whatsoever as a
stockholder of the Company.
     
     10.  ASSIGNMENT.  This Series A Warrant may not be assigned without
providing the Company an opinion satisfactory to its counsel that an exemption
from registration for the transfer exists.
     
     11.  STATE LEGENDS.  Residents of Connecticut are advised of the following:
     
         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER SECTION

           (f)  The Company and the Purchasers acknowledge and agree that the

Agreement with respect to this Section 2 directly against the Company in any 
manner permitted by applicable law, as if the Placement Agent and each

     3.   PIGGYBACK REGISTRATION
     
           (a)  If, prior to the effectiveness of the Initial Registration 
Statement or at any time the Initial Registration Statement is not effective, 
any Registrable Securities continue to be Restricted Registrable Securities, 
each time that the Company shall propose the registration under the Act of any 
shares of Common Stock of the Company, other than a registration relating to 
employee benefit plans, or a corporate reorganization or other transactions 
under Rule 145, notice of such proposed registration stating the total number 
of shares proposed to be the subject of such registration shall be given to 
the Holders of Restricted Registrable Securities and Warrants, if any have not 
yet been exercised.  The Company will use its best efforts to include in any 
registration statement filed with the Commission with regard to such proposed 
registration the number of Restricted Registrable Securities specified in 
writing by any such Holders to it within 20 days after receipt of said notice, 
provided that any Holders of any Warrant exercises such of his Warrants within 
20 days after receipt of said notice as is necessary to have included in the 
registration statement the shares of Common Stock so specified by him.  Any 
Holders who

                                       3

<PAGE>

participates in the public offering pursuant to such registration statement 
shall be entitled to all the benefits of this Agreement in connection with any 
registration hereunder, except as otherwise provided in this Section 3.  The 
right to registration provided in this Section is in addition to and not in 
lieu of the registration rights provided in Section 2 hereof.

           (b)  All Registration Expenses, as hereinafter defined, in 
connection with the offering of securities of the Company pursuant to any 
registration statement filed pursuant to this Section 3, whether or not such 
registration statement becomes effective under the Act, shall be borne by the 
Company and the Holders, provided that the Holders of Restricted Registrable 
Securities then being registered shall pay (pro rata between or among the 
Holders thereof) to the Company only that portion of such Registration 
Expenses attributable to the inclusion in such registration statement of such 
Restricted Registrable Securities (i.e., the marginal amount).  Such Holders 
shall pay all transfer taxes and out-of-pocket expenses incurred by them with 
respect to the registration and sale of the shares of Restricted Registrable 
Securities owned by them and included in such registration statement.  
Notwithstanding the foregoing, in the event the Company fails to file and 
cause to become effective, and/or thereafter maintain the effectiveness of,  a 
registration statement for the Initial Registration Period as provided for in 
Section 2 above, all Registration Expenses shall be borne by the Company.

           (c)  Notwithstanding anything to the contrary in this Section 3, 
the Holders of the Restricted Registrable Securities and Warrants shall not be 
entitled to include in any registration statement filed pursuant to this 
Section 3 Restricted Registrable Securities to the extent such inclusion would 
materially and adversely affect the proposed distribution of the Common Stock 
in respect of which registration was originally to be effected.  The number of 
Restricted Registrable Securities to be included by each Holder shall be 
allocated in accordance with Section 3(e), below.

           (d)  The piggyback registration rights provided in this Section 3 
may be exercised by the Holders of Restricted Registrable Securities from time 
to time with respect to any or all registrations under the Act of Common Stock 
of the Company in accordance with the provisions of this Section 3.

           (e)  In any circumstances in which all of the Restricted 
Registrable Securities requested to be included in a registration cannot be so 
included as a result of limitations on the aggregate number of shares of 
Restricted Registrable Securities that may be so included, the number of 
shares of Restricted Registrable Securities that may be so included shall

                                       4

<PAGE>

be allocated among the Holders of Restricted Registrable Securities pro rata 
on the basis of the number of shares of Restricted Registrable Securities that 
would be held by such Holders, assuming exercise of the Warrants; provided, 
however, that if any Holder does not request inclusion of the maximum number 
of shares of Restricted Registrable Securities allocated to him pursuant to 
the above-described procedure, then the remaining portion of his allocation 
shall be reallocated among those requesting Holders whose allocations did not 
satisfy their requests pro rata on the basis of the number of shares of 
Restricted Registrable Securities which would be held by such Holders, 
assuming exercise, and this procedure shall be repeated until all of the 
shares of Restricted Registrable Securities which may be included in the 
registration have been so allocated. Such allocation shall not operate to 
reduce the aggregate number of Restricted Registrable Securities permitted to 
be included in such registration.

     4.   REGISTRATION PROCEDURES
     
     4.1  In connection with each registration provided for in Sections 2 or 3 
hereof, the Company will as expeditiously as practicable:
     
           (a)  furnish to each seller of Restricted Registrable Securities, 
the prospectus included in such registration statement and amendments thereto 
and such other documents as such seller may reasonably request in order to 
facilitate the disposition of the Restricted Registrable Securities owned by 
such seller;

           (b)  use its best efforts to register or qualify the Restricted 
Registrable Securities included in any registration statement filed in 
accordance with Sections 2 or 3 hereof under such securities or blue sky laws 
of such jurisdictions as any such seller reasonably requests and do any and 
all other acts and things which may be reasonably necessary or advisable to 
enable such seller to consummate the disposition in such jurisdictions of the 
Restricted Registrable Securities owned by such seller; provided that the 
Company will not be required to (i) qualify generally to do business in any 
jurisdiction where it would not otherwise be required to qualify but for this 
paragraph (b), (ii) subject itself to taxation in any such jurisdiction by 
reason of such registration or qualification of any Restricted Registrable 
Securities, or (iii) consent to general service of process in any such 
jurisdiction;

           (c)  use its best efforts to cause the Restricted Registrable 
Securities covered by any such registration statement to be registered with or 
approved by such other governmental agencies or authorities as may be 
necessary by virtue of the business and operations of the Company to enable 
the seller or

                                       5

<PAGE>

sellers thereof to consummate the disposition of such Restricted Registrable
Securities;

           (d)  notify each seller of such Restricted Registrable Securities, 
at any time when a prospectus relating thereto is required to be delivered 
under the Act, of the happening of any event as a result of which the 
prospectus included in any such registration statement contains an untrue 
statement of a material fact or omits to state any material fact required to 
be stated therein or necessary to make the statements therein not misleading, 
and prepare a supplement or amendment to such prospectus so that, as 
thereafter delivered to the purchasers of such Restricted Registrable 
Securities, such prospectus will not contain an untrue statement of a material 
fact or omit to state any material fact required to be stated therein or 
necessary to make the statements therein not misleading;

           (e)  use its best efforts to cause all such Restricted Registrable 
Securities to be listed on each securities exchange on which similar 
securities issued by the Company are then listed, provided that the applicable 
listing requirements are satisfied;

          (f)  make available for inspection by any seller of such Restricted 
Registrable Securities, any underwriter participating in any disposition 
pursuant to any such registration statement, and any attorney, accountant or 
other agent retained by any such seller or underwriter (collectively, the 
"INSPECTORS"), all financial and other records, pertinent corporate documents 
and properties of the Company (collectively, the "RECORDS") as shall be 
reasonably necessary to enable them to exercise their due diligence 
responsibility, and cause the Company's officers, directors and employees to 
supply all information reasonably requested by any such inspector in 
connection with such registration statement.  All such records shall be deemed 
to be confidential and each seller shall cause the Inspectors to keep the 
information therein confidential and not disclose it to third parties unless 
(i) the disclosure of such Records is necessary to avoid or correct a 
misstatement or omission in the registration statement, (ii) the release of 
such Records is ordered pursuant to regulatory reporting requirements or a 
subpoena or other order from a court of competent jurisdiction or (iii) the 
filing of such Records as exhibits to such registration statement is required 
by the Commission's rules and regulations.  Each seller of such Restricted 
Registrable Securities agrees that it will, upon learning that disclosure of 
such Records is sought in a court of competent jurisdiction, give notice to 
the Company and allow the Company, at the Company's expense, to undertake 
appropriate action to prevent disclosure of the Records;

                                       6

<PAGE>

           (g)  in the event the sale of such Restricted Registrable 
Securities is pursuant to an underwritten offering, use its best efforts to 
obtain a "comfort" letter from the Company's independent public accountants in 
customary form and covering such matters of the type customarily covered by 
"comfort" letters as the underwriters reasonably request; and

           (h)  otherwise use its bast efforts to comply with all applicable 
rules and regulations of the Commission.

     4.2  The Company may require, as a condition to its obligations under 
this Agreement, that each seller of Restricted Registrable Securities 
registered pursuant to Sections 2 or 3 hereof furnish to the Company such 
information regarding the distribution of such securities as the Company may 
from time to time reasonably request in writing.
     
     4.3  Each seller of Restricted Registrable Securities registered pursuant 
to Sections 2 or 3 hereof agrees that, upon receipt of any notice from the 
Company of the happening of any event of the kind described in Section 4.1(d) 
hereof, such seller will forthwith discontinue disposition of such Restricted 
Registrable Securities pursuant to the registration statement covering such 
securities until such seller's receipt of the copies of the supplemented or 
amended prospectus contemplated by Section 4.1(d) hereof, and, if so directed 
by the Company, such seller will deliver to the Company (at the Company's 
expense) all copies, other than permanent file copies then in such seller's 
possession, of the prospectus covering such Restricted Registrable Securities 
that is current at the time of receipt of such notice.
     
     5.   REGISTRATION EXPENSES
     
          Registration Expenses shall be borne as set forth in Sections 2 and 
3 hereof.  Registration Expenses ("Registration Expenses") shall consist of 
all expenses incidental to the Company's performance of or compliance with 
this Agreement, including without limitation all registration and filing fees, 
fees and expenses of compliance with securities or blue sky laws (including 
reasonable fees and disbursements of counsel in connection with blue sky 
qualifications of the Restricted Registrable Securities), printing expenses, 
messenger and delivery expenses, internal expenses (including, without 
limitation, all salaries and expenses of the Company's officers and employees 
performing legal or accounting duties), the fees and expenses incurred in 
connection with the listing of such securities on each securities exchange on 
which similar securities issued by the Company are then listed, and fees and 
disbursements of counsel for the Company and of its independent certified 
public accountants (including the expenses of any

                                       7

<PAGE>

special audit or "comfort" letters required by or incident to such 
performance), securities acts liability insurance (if the Company elects to 
obtain such insurance), the reasonable fees and expenses of any special 
experts retained by the Company in connection with any registration of 
Restricted Registrable Securities.

     6.   INDEMNIFICATION: CONTRIBUTION
     
           (a)  INDEMNIFICATION BY THE COMPANY.  The Company agrees to 
indemnify, to the full extent permitted by law, each seller of Restricted 
Registrable Securities, its officers and directors and each person who 
controls such seller (within the meaning of the Act) against all losses, 
claims, damages, liabilities and expenses caused by any untrue or alleged 
untrue statement of material fact contained in any registration statement, 
prospectus or preliminary prospectus or amendment or supplement thereto or any 
omission or alleged omission to state therein a material fact required to be 
stated therein or necessary to make the statements therein, in the light of 
the circumstances under which they were made not misleading, and the Company 
will reimburse legal or other expenses reasonably incurred by such seller in 
investigating or defending any claims relating to or arising from such untrue 
statements or omissions, in all cases except insofar as such are caused by (i) 
statements or omissions made in reliance upon or contained in any information 
with respect to such seller furnished in writing to the Company by such seller 
expressly for use therein or (ii) such seller's failure to deliver a copy of 
the final prospectus as then amended or supplemented after the Company has 
furnished such seller with a sufficient number of copies of the same, but only 
if delivery of same is required by law and if same would have cured the defect 
giving rise to any such loss, claim, damage, liability or expense.  Such 
indemnification shall be effective irrespective of any investigation by any 
seller.

           (b)  INDEMNIFICATION BY SELLERS OF RESTRICTED REGISTRABLE 
SECURITIES.  In connection with any registration statement relating to a sale 
of Restricted Registrable Securities, each seller thereof will furnish to the 
Company in writing such information and affidavits with respect to such seller 
as the Company reasonably requests for use in connection with any such 
registration statement (or prospectus contained therein) and will indemnify, 
to the extent permitted by law, the Company, its directors, its officers who 
sign the registration statement and each person who controls the Company 
(within the meaning of the Act) against any losses, claims, damages, 
liabilities and expenses resulting from any untrue or alleged untrue statement 
of material fact or any omission or alleged omission of a material fact 
required to be stated in such registration statement or prospectus or any 
amendment thereof or supplement thereto or necessary to make the statements 
therein,

                              8

<PAGE>

in the light of the circumstances under which they were made, not misleading, 
in each case to the extent, but only to the extent, that any such loss, 
liability, claim, damage or expense arises out of or is based upon any such 
untrue statement or alleged untrue statement or omission or alleged omission 
made therein in reliance upon and in conformity with such written information 
or affidavits relating to such seller furnished to the Company by such seller 
expressly for use therein.

           (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS.  Any person entitled 
to indemnification hereunder agrees to give prompt written notice to the 
indemnifying party after the receipt by such person of any written notice of 
the commencement of any action, suit, proceeding or investigation or threat 
thereof made in writing for which such person will claim indemnification or 
contribution pursuant to this Agreement and, unless in the reasonable judgment 
of such indemnified party a conflict of interest may exist between such 
indemnified party and the indem-nifying party, shall permit the indemnifying 
party to assume the defense of such claim with counsel reasonably satisfactory 
to such indemnified party.  If the indemnifying party is not entitled to, or 
elects not to, assume the defense of a claim, it will not be obligated to pay 
the fees and expenses of more than one counsel for the indemnified party with 
respect to such claim. The indemnifying party will not be subject to any 
liability for any settlement made without its consent.  Failure of notice by a 
seller of Restricted Registrable Securities entitled to indemnification 
hereunder will not relieve the Company of its obligations under this Section 6 
unless the Company is actually prejudiced thereby.

          (d)  CONTRIBUTION
          
                (i)  If the indemnification provided for in this Section 6 
from the indemnifying party is unavailable to an indemnified party hereunder 
in respect of any losses, claims, damages, liabilities or expenses referred 
to therein, then the indemnifying party, in lieu of indemnifying such 
indemnified party, shall contribute (on the basis of relative fault) to the 
amount paid or payable by such indemnified party as a result of such losses, 
claims, damages, liabilities or expenses.  The relative fault of such 
indemnifying and indemnified parties shall be determined by reference to, 
among other things, whether any action in question, including any untrue or 
alleged untrue statement of a material fact or omission or alleged omission 
to state a material fact, has been made by, or relates to informa-tion 
supplied by, such indemnifying or indemnified parties, and the parties' 
relative intent, knowledge, access to information and opportunity to correct 
or prevent such action.  The amount paid or payable by a party as a result of 
the losses, claims, damages, liabilities and expenses referred to above shall 
be deemed to include, subject to the limitations set forth in

                              9

<PAGE>

Section 6(c), any legal or other fees or expenses reasonably incurred by such 
party in connection with any investigation or proceeding.  Notwithstanding the 
provisions of this Section 6(5)(i), in no case shall any seller of Restricted 
Registrable Securities be liable or responsible for any amount in excess of 
the net proceeds received by such seller from the sale of the Restricted 
Registrable Securities of such seller which are included in any registration 
statement contemplated by this Agreement.

               (ii)  No person guilty of fraudulent misrepresentation (within 
the meaning of Section 11(f) of the Act) shall be entitled to contribution 
from any person who was not guilty of such fraudulent misrepresentation.

              (iii)  If indemnification is available under this Section 6, the 
indemnifying parties shall indemnify each indemnified party to the full extent 
provided in Sections 6(a) and (b) without regard to the relative fault of said 
indemnifying party or indemnified party.

     7.   PARTICIPATION IN UNDERWRITTEN REGISTRATIONS
     
           (a)  No Holder of Restricted Registrable Securities may 
participate, pursuant to Section 3 hereof, in any underwritten offering of 
Common Stock of the Company, notice of which is given pursuant to Section 3 
hereof, unless such owner (i) agrees to sell its Restricted Registrable 
Securities pursuant to the underwriting arrangements approved by the Company 
and its counsel and (ii) completes and executes all questionnaires, powers of 
attorney, indemnities, underwriting agreements and other documents reasonably 
required under the terms of such underwriting arrangements.

           (b)  The Company shall have no obligation under Section 3 to the 
extent that any underwriter in connection with the registered public offering 
reasonably notifies the Company of its determination that the Restricted 
Registrable Securities or a portion thereof should be excluded therefrom.  In 
the event that a portion is to be excluded, the number of Restricted 
Registrable Securities to be included by each Holder shall be allocated in 
accordance with Section 3(e), above.

     8.   RULE 144
     
          The Company covenants that it will timely file the reports required 
to be filed by it under the Act and the Exchange Act and the rules and 
regulations adopted by the Commission thereunder, and it will take such 
further action as any record owner of Restricted Registrable Securities may 
reasonably request, all to the extent required from time to time to enable 
such owner to sell Restricted Registrable Securities without

                                      10

<PAGE>

registration under the Act within the limitation of the exemptions provided by 
(a) Rule 144 under the Act, as such Rule may be amended from time to time, or 
(b) any similar rule or regulation hereafter adopted by the Commission.  Upon 
the request of any record owner of Restricted Registrable Securities, the 
Company will deliver to such owner a written statement as to whether it has 
complied with such requirements.

     9.   TERMINATION
     
          This Agreement shall terminate on the fifth anniversary of the final 
closing (as that term is defined in the Confidential Private Placement 
Memorandum dated June 1, 1996).  The provisions of Section 6 hereof shall 
survive such termination.
          
     10.  MISCELLANEOUS
     
           (a)  AMENDMENTS AND WAIVERS.  Except as otherwise provided herein, 
the provisions of this Agreement may not be amended, modified or supplemented,

given unless the Company has obtained the written consent of Holders of at 
least a majority in number of shares of Restricted Registrable Securities then 
outstanding affected by such amendment, modification, supplement, waiver or 
departure.  Such amendment, modification or supplement, waiver or departure, 
if consented to in writing by such majority of Holders, shall thereby amend, 
modify or supplement, waive or act to consent to depart from, this Agreement

           (f)  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND

                             SERACARE, INC.

                     REGISTRATION RIGHTS AGREEMENT

     This Registration Rights Agreement (this "AGREEMENT") is made and 
entered into on October 23, 1996, by and among Seracare, Inc., a Delaware 
corporation (the "COMPANY"), and those individuals and entities (the 
"PURCHASERS") purchasing units (the "UNITS"), each consisting of 
five-thousand shares (the "SHARES") of the Company's Common Stock, with 
$0.001 par value (the "COMMON STOCK"), and two-thousand five-hundred warrants 
to purchase one share of Common Stock exercisable at $2.75 (the "A WARRANTS" 
or "WARRANTS").
     
     In order to induce the Purchasers to enter into the Subscription 
Agreements, the Company has agreed to provide the registration rights set 
forth in this Agreement.  The execution of this Agreement is a condition to 
the closing under the Subscription Agreements.  Capitalized terms used herein 
without definition shall have the meaning set forth in the Subscription 
Agreements.
     
The parties hereby agree as follows:

     1.   DEFINITIONS.

          (a)  "REGISTRABLE SECURITIES" means each of the following:  (i) the 
shares of Common Stock included in the Units to be sold to the Purchasers 
pursuant to the Subscription Agreements, and (ii) the shares of Common Stock 
issued or issuable upon exercise of the Warrants, provided that Registrable 
Securities shall not include any shares which (x) can be publicly resold by 
the holders thereof without registration under the Securities Act of 1933, as 
amended (the "ACT") or the availability of an exemption thereunder, (y) which 
are currently registered under an effective registration statement, or (z) 
which have been sold to the public or in a private transaction in which the 
transferor's rights under this agreement are not assigned.

          (b)  "RESTRICTED REGISTRABLE SECURITIES" means the Registrable 
Securities until (i) a registration statement covering such Registrable 
Securities has been declared effective and they have been disposed of 
pursuant to such effective registration statement, (ii) they are eligible for 
distribution to the public pursuant to Rule 144 (or any similar provision 
then in force) under the Act or (iii) they have been otherwise transferred 
and the Company has delivered new certificates or other evidences of 
ownership for them not subject to any stop transfer order or other 
restriction on transfer (including, without limitation, sale).

                                       1
<PAGE>

          (c)  "HOLDER(S)" means (i) the Purchasers who are the record owners 
of Registrable Securities and/or Restricted Registrable Securities, as 
applicable; and/or (ii) the record owners of Registrable Securities and/or 
Restricted Registrable Securities, as applicable, to whom registration rights 
have been transferred in accordance with Section 10(c) below.

     2.   MANDATORY REGISTRATION
     
          (a)  The Company will use its best efforts to file with the 
Securities and Exchange Commission (the "COMMISSION") and to cause to become 
effective no later than that date which is 270 days from the Final 
Closing(such day is referred to herein as the "EFFECTIVE DATE"), a 
registration statement (the "INITIAL REGISTRATION STATEMENT") under the Act 
for the offering and sale of the Restricted Registrable Securities, and, 
further, the Company shall use its best efforts to keep such Initial 
Registration Statement effective through the earliest of: (i) the expiration 
date of all the Warrants issued to the Holders, and (ii) the exercise in full 
of all Warrants by the Holders, and (iii) the redemption of all Warrants 
issued to the Holders by the Company, but in any event, with respect to the 
Shares, until such time as the Shares are no longer deemed Restricted 
Registrable Securities hereunder (the period during which  the Initial 
Registration Statement remains effective is hereinafter referred to as the 
"Initial Registration Period.")

          (b)  The Company further agrees, if necessary, to supplement or 
make amendments to the Initial Registration Statement and any prospectus 
contained therein, if required by the Initial Registration Statement form 
utilized by the Company or by the instructions applicable to such 
registration form or by the Act or the rules and regulations thereunder, and 
the Company agrees to furnish copies of such Initial Registration Statement, 
prospectus, supplement or amendment as soon as practicable after its being 
used and/or filed with the Commission to the security holders whose 
Restricted Registrable Securities are included in the Initial Registration 
Statement.

          (c)  The Company will pay all Registration Expenses (as hereinafter 
defined) incurred in connection with the Company's registration obligations 
pursuant to this Section 2.

          (d)  The Company agrees to take whatever actions are reasonably 
deemed necessary by First Equity Capital Securities, Inc. (the "PLACEMENT 
AGENT") in order to assist the Investors, First Equity, and their agents when 
selling securities of the Company in complying with Rule 15c6-1 of the 
Securities Exchange Act of 1934, as amended.

          (e)  The Company will make available to its security holders, as 
soon as reasonably practicable, an earnings statement

                                       2

<PAGE>

covering a period of twelve months, commencing on the first day of the fiscal 
quarter next succeeding the effective date of each sale of any Restricted 
Registrable Securities pursuant to the Initial Registration Statement, which 
earnings statement shall satisfy the provisions of Section 11(a) of the Act.

          (f)  The Company and the Purchasers acknowledge and agree that the 
rights of First Equity Capital Securities, Inc. (the "PLACEMENT AGENT") and 
any other dealers or registered representatives thereof chosen by the 
Placement Agent with the approval of the Company that are members of the 
National Association of Securities Dealers, Inc. (each, a "SELECTED DEALER" 
and collectively, the "SELECTED DEALERS"), under Section 3 of that certain 
Dealer Registration Rights Agreement dated the date hereof by and between the 
Company and the Placement Agent (the "DEALER REGISTRATION RIGHTS AGREEMENT"), 
include the right of the Placement Agent and/or any Selected Dealer to have 
added to and made a part of the Initial Registration Statement the number of 
shares of Common Stock of the Company (including those shares included in the 
Dealer Warrants and underlying the "Series B Warrants" as such term is 
defined in the Dealer Registration Rights Agreement) requested in writing by 
the Placement Agent and/or the Selected Dealers.  The Placement Agent and 
each Selected Dealer shall each be direct third party beneficiaries of this 
Section 2 and the rights arising therefrom, and may enforce the provisions of 
this Agreement with respect to this Section 2 directly against the Company in 
any manner permitted by applicable law, as if the Placement Agent and each 
Selected Dealer were signatories hereto.

     3.   PIGGYBACK REGISTRATION
     
          (a)  If, prior to the effectiveness of the Initial Registration 
Statement or at any time the Initial Registration Statement is not effective, 
any Registrable Securities continue to be Restricted Registrable Securities, 
each time that the Company shall propose the registration under the Act of 
any shares of Common Stock of the Company, other than a registration relating 
to employee benefit plans, or a corporate reorganization or other 
transactions under Rule 145, notice of such proposed registration stating the 
total number of shares proposed to be the subject of such registration shall 
be given to the Holders of Restricted Registrable Securities and Warrants, if 
any have not yet been exercised.  The Company will use its best efforts to 
include in any registration statement filed with the Commission with regard 
to such proposed registration the number of Restricted Registrable Securities 
specified in writing by any such Holders to it within 20 days after receipt 
of said notice, provided that any Holders of any Warrant exercises such of 
his Warrants within 20 days after receipt of said notice as is necessary to 
have included in the registration statement the shares of Common Stock so 
specified by him.  Any Holders who

                                3
<PAGE>

participates in the public offering pursuant to such registration statement 
shall be entitled to all the benefits of this Agreement in connection with 
any registration hereunder, except as otherwise provided in this Section 3.  
The right to registration provided in this Section is in addition to and not 
in lieu of the registration rights provided in Section 2 hereof.

          (b)  All Registration Expenses, as hereinafter defined, in 
connection with the offering of securities of the Company pursuant to any 
registration statement filed pursuant to this Section 3, whether or not such 
registration statement becomes effective under the Act, shall be borne by the 
Company and the Holders, provided that the Holders of Restricted Registrable 
Securities then being registered shall pay (pro rata between or among the 
Holders thereof) to the Company only that portion of such Registration 
Expenses attributable to the inclusion in such registration statement of such 
Restricted Registrable Securities (i.e., the marginal amount).  Such Holders 
shall pay all transfer taxes and out-of-pocket expenses incurred by them with 
respect to the registration and sale of the shares of Restricted Registrable 
Securities owned by them and included in such registration statement.  
Notwithstanding the foregoing, in the event the Company fails to file and 
cause to become effective, and/or thereafter maintain the effectiveness of,  
a registration statement for the Initial Registration Period as provided for 
in Section 2 above, all Registration Expenses shall be borne by the Company.

          (c)  Notwithstanding anything to the contrary in this Section 3, 
the Holders of the Restricted Registrable Securities and Warrants shall not 
be entitled to include in any registration statement filed pursuant to this 
Section 3 Restricted Registrable Securities to the extent such inclusion 
would materially and adversely affect the proposed distribution of the Common 
Stock in respect of which registration was originally to be effected.  The 
number of Restricted Registrable Securities to be included by each Holder 
shall be allocated in accordance with Section 3(e), below.

          (d)  The piggyback registration rights provided in this Section 3 
may be exercised by the Holders of Restricted Registrable Securities from 
time to time with respect to any or all registrations under the Act of Common 
Stock of the Company in accordance with the provisions of this Section 3.

          (e)  In any circumstances in which all of the Restricted 
Registrable Securities requested to be included in a registration cannot be 
so included as a result of limitations on the aggregate number of shares of 
Restricted Registrable Securities that may be so included, the number of 
shares of Restricted Registrable Securities that may be so included shall

                                       4
<PAGE>

be allocated among the Holders of Restricted Registrable Securities pro rata 
on the basis of the number of shares of Restricted Registrable Securities 
that would be held by such Holders, assuming exercise of the Warrants; 
provided, however, that if any Holder does not request inclusion of the 
maximum number of shares of Restricted Registrable Securities allocated to 
him pursuant to the above-described procedure, then the remaining portion of 
his allocation shall be reallocated among those requesting Holders whose 
allocations did not satisfy their requests pro rata on the basis of the 
number of shares of Restricted Registrable Securities which would be held by 
such Holders, assuming exercise, and this procedure shall be repeated until 
all of the shares of Restricted Registrable Securities which may be included 
in the registration have been so allocated. Such allocation shall not operate 
to reduce the aggregate number of Restricted Registrable Securities permitted 
to be included in such registration.

     4.   REGISTRATION PROCEDURES
     
     4.1  In connection with each registration provided for in Sections 2 or 
3 hereof, the Company will as expeditiously as practicable:
     
          (a)  furnish to each seller of Restricted Registrable Securities, 
the prospectus included in such registration statement and amendments thereto 
and such other documents as such seller may reasonably request in order to 
facilitate the disposition of the Restricted Registrable Securities owned by 
such seller;

          (b)  use its best efforts to register or qualify the Restricted 
Registrable Securities included in any registration statement filed in 
accordance with Sections 2 or 3 hereof under such securities or blue sky laws 
of such jurisdictions as any such seller reasonably requests and do any and 
all other acts and things which may be reasonably necessary or advisable to 
enable such seller to consummate the disposition in such jurisdictions of the 
Restricted Registrable Securities owned by such seller; provided that the 
Company will not be required to (i) qualify generally to do business in any 
jurisdiction where it would not otherwise be required to qualify but for this 
paragraph (b), (ii) subject itself to taxation in any such jurisdiction by 
reason of such registration or qualification of any Restricted Registrable 
Securities, or (iii) consent to general service of process in any such 
jurisdiction;

          (c)  use its best efforts to cause the Restricted Registrable 
Securities covered by any such registration statement to be registered with 
or approved by such other governmental agencies or authorities as may be 
necessary by virtue of the business and operations of the Company to enable 
the seller or

                                       5
<PAGE>

sellers thereof to consummate the disposition of such Restricted Registrable 
Securities;

          (d)  notify each seller of such Restricted Registrable Securities, 
at any time when a prospectus relating thereto is required to be delivered 
under the Act, of the happening of any event as a result of which the 
prospectus included in any such registration statement contains an untrue 
statement of a material fact or omits to state any material fact required to 
be stated therein or necessary to make the statements therein not misleading, 
and prepare a supplement or amendment to such prospectus so that, as 
thereafter delivered to the purchasers of such Restricted Registrable 
Securities, such prospectus will not contain an untrue statement of a 
material fact or omit to state any material fact required to be stated 
therein or necessary to make the statements therein not misleading;

          (e)  use its best efforts to cause all such Restricted Registrable 
Securities to be listed on each securities exchange on which similar 
securities issued by the Company are then listed, provided that the 
applicable listing requirements are satisfied;

          (f)  make available for inspection by any seller of such Restricted 
Registrable Securities, any underwriter participating in any disposition 
pursuant to any such registration statement, and any attorney, accountant or 
other agent retained by any such seller or underwriter (collectively, the 
"INSPECTORS"), all financial and other records, pertinent corporate documents 
and properties of the Company (collectively, the "RECORDS") as shall be 
reasonably necessary to enable them to exercise their due diligence 
responsibility, and cause the Company's officers, directors and employees to 
supply all information reasonably requested by any such inspector in 
connection with such registration statement.  All such records shall be 
deemed to be confidential and each seller shall cause the Inspectors to keep 
the information therein confidential and not disclose it to third parties 
unless (i) the disclosure of such Records is necessary to avoid or correct a 
misstatement or omission in the registration statement, (ii) the release of 
such Records is ordered pursuant to regulatory reporting requirements or a 
subpoena or other order from a court of competent jurisdiction or (iii) the 
filing of such Records as exhibits to such registration statement is required 
by the Commission's rules and regulations.  Each seller of such Restricted 
Registrable Securities agrees that it will, upon learning that disclosure of 
such Records is sought in a court of competent jurisdiction, give notice to 
the Company and allow the Company, at the Company's expense, to undertake 
appropriate action to prevent disclosure of the Records;

                                       6

<PAGE>

          (g)  in the event the sale of such Restricted Registrable 
Securities is pursuant to an underwritten offering, use its best efforts to 
obtain a "comfort" letter from the Company's independent public accountants 
in customary form and covering such matters of the type customarily covered 
by "comfort" letters as the underwriters reasonably request; and

          (h)  otherwise use its best efforts to comply with all applicable 
rules and regulations of the Commission.

     4.2  The Company may require, as a condition to its obligations under 
this Agreement, that each seller of Restricted Registrable Securities 
registered pursuant to Sections 2 or 3 hereof furnish to the Company such 
information regarding the distribution of such securities as the Company may 
from time to time reasonably request in writing.
     
     4.3  Each seller of Restricted Registrable Securities registered 
pursuant to Sections 2 or 3 hereof agrees that, upon receipt of any notice 
from the Company of the happening of any event of the kind described in 
Section 4.1(d) hereof, such seller will forthwith discontinue disposition of 
such Restricted Registrable Securities pursuant to the registration statement 
covering such securities until such seller's receipt of the copies of the 
supplemented or amended prospectus contemplated by Section 4.1(d) hereof, 
and, if so directed by the Company, such seller will deliver to the Company 
(at the Company's expense) all copies, other than permanent file copies then 
in such seller's possession, of the prospectus covering such Restricted 
Registrable Securities that is current at the time of receipt of such notice.

     5.   REGISTRATION EXPENSES

          Registration Expenses shall be borne as set forth in Sections 2 and 3
hereof.  Registration Expenses ("Registration Expenses") shall consist of all
expenses incidental to the Company's performance of or compliance with this
Agreement, including without limitation all registration and filing fees, fees
and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel in connection with blue sky
qualifications of the Restricted Registrable Securities), printing expenses,
messenger and delivery expenses, internal expenses (including, without
limitation, all salaries and expenses of the Company's officers and employees
performing legal or accounting duties), the fees and expenses incurred in
connection with the listing of such securities on each securities exchange on
which similar securities issued by the Company are then listed, and fees and
disbursements of counsel for the Company and of its independent certified public
accountants (including the expenses of any

                                       7

<PAGE>

special audit or "comfort" letters required by or incident to such 
performance), securities acts liability insurance (if the Company elects to 
obtain such insurance), the reasonable fees and expenses of any special 
experts retained by the Company in connection with any registration of 
Restricted Registrable Securities.

     6.   INDEMNIFICATION; CONTRIBUTION
     
          (a)  INDEMNIFICATION BY THE COMPANY.  The Company agrees to 
indemnify, to the full extent permitted by law, each seller of Restricted 
Registrable Securities, its officers and directors and each person who 
controls such seller (within the meaning of the Act) against all losses, 
claims, damages, liabilities and expenses caused by any untrue or alleged 
untrue statement of material fact contained in any registration statement, 
prospectus or preliminary prospectus or amendment or supplement thereto or 
any omission or alleged omission to state therein a material fact required to 
be stated therein or necessary to make the statements therein, in the light 
of the circumstances under which they were made not misleading, and the 
Company will reimburse legal or other expenses reasonably incurred by such 
seller in investigating or defending any claims relating to or arising from 
such untrue statements or omissions, in all cases except insofar as such are 
caused by (i) statements or omissions made in reliance upon or contained in 
any information with respect to such seller furnished in writing to the 
Company by such seller expressly for use therein or (ii) such seller's 
failure to deliver a copy of the final prospectus as then amended or 
supplemented after the Company has furnished such seller with a sufficient 
number of copies of the same, but only if delivery of same is required by law 
and if same would have cured the defect giving rise to any such loss, claim, 
damage, liability or expense.  Such indemnification shall be effective 
irrespective of any investigation by any seller.

          (b)  INDEMNIFICATION BY SELLERS OF RESTRICTED REGISTRABLE 
SECURITIES.  In connection with any registration statement relating to a sale 
of Restricted Registrable Securities, each seller thereof will furnish to the 
Company in writing such information and affidavits with respect to such 
seller as the Company reasonably requests for use in connection with any such 
registration statement (or prospectus contained therein) and will indemnify, 
to the extent permitted by law, the Company, its directors, its officers who 
sign the registration statement and each person who controls the Company 
(within the meaning of the Act) against any losses, claims, damages, 
liabilities and expenses resulting from any untrue or alleged untrue 
statement of material fact or any omission or alleged omission of a material 
fact required to be stated in such registration statement or prospectus or 
any amendment thereof or supplement thereto or necessary to make the 
statements therein,  

                                       8

<PAGE>

in the light of the circumstances under which they were made, not misleading, 
in each case to the extent, but only to the extent, that any such loss, 
liability, claim, damage or expense arises out of or is based upon any such 
untrue statement or alleged untrue statement or omission or alleged omission 
made therein in reliance upon and in conformity with such written information 
or affidavits relating to such seller furnished to the Company by such seller 
expressly for use therein.

          (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS.  Any person entitled 
to indemnification hereunder agrees to give prompt written notice to the 
indemnifying party after the receipt by such person of any written notice of 
the commencement of any action, suit, proceeding or investigation or threat 
thereof made in writing for which such person will claim indemnification or 
contribution pursuant to this Agreement and, unless in the reasonable 
judgment of such indemnified party a conflict of interest may exist between 
such indemnified party and the indemnifying party, shall permit the 
indemnifying party to assume the defense of such claim with counsel 
reasonably satisfactory to such indemnified party.  If the indemnifying party 
is not entitled to, or elects not to, assume the defense of a claim, it will 
not be obligated to pay the fees and expenses of more than one counsel for 
the indemnified party with respect to such claim.  The indemnifying party 
will not be subject to any liability for any settlement made without its 
consent.  Failure of notice by a seller of Restricted Registrable Securities 
entitled to indemnification hereunder will not relieve the Company of its 
obligations under this Section 6 unless the Company is actually prejudiced 
thereby.

          (d)  CONTRIBUTION
          
                (i)  If the indemnification provided for in this Section 6 from
the indemnifying party is unavailable to an indemnified party hereunder in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute (on the basis of relative fault) to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities or expenses.  The relative fault of such indemnifying and
indemnified parties shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying or
indemnified parties, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action.  The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include, subject to the
limitations set forth in 
             
                                       9

<PAGE>

Section 6(c), any legal or other fees or expenses reasonably incurred by such 
party in connection with any investigation or proceeding.  Notwithstanding 
the provisions of this Section 6(d)(i), in no case shall any seller of 
Restricted Registrable Securities be liable or responsible for any amount in

certificates may be issued and delivered by the Company or transferred by the
Warrant Holders with the same force and affect as though the person who signed
such certificate had not ceased to be an officer of the Company; any certificate
signed on behalf of the Company by any person, who at the actual date of the
execution of such. certificate was a proper officer of the Company, shall be
proper notwithstanding that at the date of execution of this Agreement any such
person was not such an officer.

<PAGE>

aggregate of 600 days within three years after the final closing of the Private

tolled until the Dealer Shares and the Series B Warrant Shares shall have been
subject to an effective registration for an aggregate of 600 days and (y) in no
event shall the Dealer Warrants terminate under this clause (i) unless a
registration statement covering the Dealer Shares and the Series B Warrant
Shares shall have then been in effect for 45 days prior to such termination, and
(ii) six years from the date of issuance, unless extended by a majority vote of
the Board of Directors for such length of time as they, in their sole
discretion, deem reasonable and necessary.  Each date on which a Dealer Warrant
is exercised is hereafter referred to as a "DEALER WARRANT EXERCISE DATE".

           (ii) Subject to the provisions of Section 9 hereof the Series B
Warrants, as they may be adjusted as set forth herein, may be exercised at a
price (the "SERIES B WARRANT EXERCISE PRICE") of $2.75 per share of Common

surrender for exercise of the certificate representing such warrant. The
exercise form shall be executed by the Warrant Holder thereof or his attorney
duly authorized in writing and shall be delivered together with payment to the
Company at its corporate offices located at 1875 Century Park East, Suite 2130,
Los Angeles, California 90067 (the "CORPORATE OFFICE"), or at any such other
office or agency as the Company may designate, in cash or by official bank or
certified check, of an amount equal to the aggregate Exercise Price, as adjusted
pursuant to Section 9 hereof, in lawful money of the United States of America.

           (c)  Unless Dealer Shares or Series B Warrant Shares may not be
issued as provided herein, the person entitled to receive the number of Dealer
Shares and/or Series B Warrant Shares deliverable on exercise shall be treated
for all purposes as the holder of such Dealer Shares and/or Series B Warrant
Shares, as applicable, as of the close of business on the Exercise Date. The
Company shall not be obligated to issue any fractional share interest in Dealer
Shares or Series B Warrant Shares issuable or deliverable on the exercise of any
Dealer Warrant or any Series B Warrant or scrip or cash therefore and such
fractional shares shall be of no value whatsoever.

Company, at its own expense,



                                        4

<PAGE>

shall cause to be issued and delivered to the person or persons entitled to
receive the same, a certificate or certificates in the name requested by the
holder of such Dealer Warrant or Series B Warrant for the number of Dealer
Shares or Series B Warrant Shares deliverable on such exercise.  No adjustment

Shares delivered on exercise of any Dealer Warrant or Series B Warrant.  All
shares of Common Stock or other securities delivered upon the exercise of the
Dealer Warrants or the Series B Warrants shall be validly issued, fully paid and
nonassessable.

           (e)  Neither the Dealer Warrants nor the Series B Warrants shall
entitle the holder thereof to any of the rights of shareholders or to any
dividend declared on the Common Stock unless such holder or holders shall have
exercised the Dealer Warrants or the Series B Warrants, as applicable, prior to
the record date fixed by the Board of Directors for the determination of holders
of Common Stock entitled to such dividends or other rights.

     4.   REGISTRATION RIGHTS.

          The Dealer Warrant Holders and the Series B Warrant Holders shall have

     5.   RESERVATION OF SHARES AND PAYMENT OF TAXES.

           (a)  The Company covenants that it shall at all times reserve and
have available from its authorized Common Stock such number of shares as shall
then be issuable on the exercise of all outstanding Dealer Warrants and Series B
Warrants. The Company covenants that all the Dealer Shares and all the Series B
Warrant Shares shall be duly and validly issued, fully paid and non- assessable,
and shall be free from all taxes, liens and charges with respect to the issuance
thereof.

          (b)  The Company shall pay all documentary, stamp or similar taxes and
other government charges that may be imposed with respect of the issuance of the
Dealer Warrants and the Series B Warrants, and/or the issuance and delivery of
any Common Stock constituting the Dealer Shares or the Series B Warrant Shares
upon exercise of the Dealer Warrants and the Series B Warrants, as applicable.
In the event the Common Stock constituting the Dealer Shares or the shares
issuable upon the exercise of the Series B Warrants are to be delivered in a
name other than the name of the initial Dealer Warrant Holder, no such delivery
shall be made unless the person requesting the same has


                                        5

<PAGE>

paid to the Company the amount of any such taxes, charges, or transfer fees
incident thereto.

     6.   REGISTRATION OF TRANSFER.

           (a)  The Dealer Warrant Certificates and the Series B Warrant

therefor the Dealer Warrant Certificates or Series B Warrant Certificates, as
applicable, in the names and amounts that the holder making the transfer shall

reasonably satisfactory to the Company. The established transfer fee for any
registration of transfer of certificates shall be paid by the Warrant Holder or
the person presenting the certificate for transfer.

           (b)  Prior to due presentment for registration or transfer thereof,
the Company may treat the Registered Holder of any certificate as the absolute
owner thereof (notwithstanding any notations of ownership or writing thereon
made by anyone), and the parties hereto shall not be affected by any notice to
the contrary.

     7.   LOSS OR MUTILATION.

          On receipt by the Company of evidence satisfactory to the Company as

     8.   NO REDEMPTION OPTION.

          Neither the Dealer Warrants nor the Series B Warrants may be called or
redeemed by the Company.

     9.   ADJUSTMENT OF EXERCISE PRICE
          AND NUMBER OF SHARES PURCHASABLE.

          For purposes hereof, the term "EXERCISE PRICE" shall mean (i) with
respect to the Dealer Warrants, $3.00, and (ii) with respect to the Series B
Warrants, $2.75.  The Exercise Price and the number of shares of Common Stock
purchasable pursuant to the Dealer Warrants and the Series B Warrants shall be
subject to adjustment from time to time as hereinafter set forth in this Section
9; PROVIDED, HOWEVER, that no adjustment shall be made unless such adjustment
would not conflict with the applicable rules of the National Association of
Securities Dealers, Inc.

          9.1  ADJUSTMENTS.  The number of Dealer Shares and Series B Warrant
Shares purchasable upon the exercise of the Dealer Warrants and the Series B
Warrants and the Exercise Price shall be subject to adjustment as follows:

          (a)  In case the Company shall (i) pay a dividend in shares of Common
     Stock or make a distribution in shares of Common Stock, (ii) subdivide its
     outstanding shares of Common Stock, (iii) combine its outstanding shares of
     Common Stock into a smaller number of shares of Common Stock or (iv) issue
     by reclassification of its Common Stock other securities of the Company,
     the number of Dealer Shares and Series B Warrant Shares purchasable upon
     exercise of the Dealer Warrants and the Series B Warrants, respectively,
     immediately prior thereto shall be adjusted so that the holder of any such
     Dealer Warrant or Series B Warrant shall be entitled to receive the kind
     and number of Common Stock or other securities of the Company which it
     would have owned or would have been entitled to receive after the
     happening of any of the events described above, had the Dealer Warrants and
     the Series B Warrants been exercised immediately prior to the happening of
     such event or any record date with respect thereto. Any adjustment made
     pursuant to this Paragraph (a) shall become effective  immediately after
     the effective date of such event retroactive to the record date, if any,
     for such event.

          (b)  In case the Company shall issue rights, options, warrants or
     convertible securities to all or substantially all holders of its Common
     Stock, without any consideration, entitling them to subscribe for or to
     purchase shares of Common Stock at a price per share which is lower at the
     record date mentioned below than the then Current Market Price (as defined
     below), the number of Dealer Shares and Series B Warrant Shares thereafter
     purchasable upon the


                                        7

<PAGE>

     exercise of a Dealer Warrant and a Series B Warrant, respectively, shall be
     determined by multiplying the number of Dealer Shares and Series B Warrant
     Shares theretofore purchasable upon exercise of each Dealer Warrant and
     Series B Warrant by a fraction, of which the numerator shall be (1) the
     number of shares of Common Stock outstanding immediately prior to the
     issuance of such rights, options or warrants plus (2) the number of
     additional shares of Common Stock offered for subscription or purchase, and
     of which the denominator shall be (x) the number of shares of Common Stock
     outstanding immediately prior to the issuance of such rights, options or
     warrants plus (y) the number of shares which the aggregate offering price
     of the total number of shares offered would purchase at the Current Market
     Price. Such adjustment shall be made whenever such rights, options or
     warrants are issued, and shall become effective immediately and
     retroactively after the record date for the determination of shareholders
     entitled to receive such rights, options or warrants.

          (c)  In case the Company shall distribute to all or substantially all
     holders of its shares of Common Stock evidences of its indebtedness or
     assets (excluding cash dividends or distributions out of earnings) or
     rights, options, warrants or convertible securities containing the right to
     subscribe for or purchase shares of Common Stock (excluding those referred
     to in paragraph (b) above), then, in each case, the number of Dealer Shares
     and Series B Warrant Shares thereafter purchasable upon the exercise of the
     Dealer Warrants and the Series B Warrants, respectively, shall be
     determined by multiplying the number of Dealer Shares and Series B Warrant
     Shares, as applicable, theretofore purchasable upon exercise of the Dealer
     Warrants and the Series B Warrants, respectively, by a fraction, of which
     the numerator shall be the then Current Market Price on the date of such
     distribution, and of which the denominator shall be such Current Market
     Price on such date minus the then fair value of the portion of the assets
     or evidence of indebtedness so distributed or of such subscription rights,
     options or warrants applicable to one share. Such adjustment shall be made
     whenever any such distribution is made and shall become effective on the
     date of distribution retroactive to the record date for the determination
     of shareholders entitled to receive such distribution.

          (d)  No adjustment in the number of Dealer Shares or Series B Warrant
     Shares purchasable hereunder shall be required unless such adjustment would
     require an increase or decrease of at least one percent (1%) in the number
     of shares then purchasable upon the exercise; PROVIDED, HOWEVER. that any
     adjustments which by reason of this Paragraph (d) are not required to be
     made immediately shall


                                        8

<PAGE>

     be carried forward and taken into account in any subsequent adjustment.

          (e)  Whenever the number of Dealer Shares or Series B  Warrant 
     Shares purchasable upon the exercise of a Dealer Warrant or Series B 
     Warrant is adjusted as herein provided, the Exercise Price payable upon 
     exercise of a Dealer Warrantor Series B Warrant shall be adjusted by 
     multiplying the Exercise Price immediately prior to such adjustment by a 
     fraction, of which the numerator shall be the number of Dealer Warrant 
     Shares or Series B Warrant Shares purchasable upon the exercise of the 
     Dealer Warrant or Series B Warrant, respectively, immediately prior to 
     such adjustment, and of which the denominator shall be the number of 
     shares so purchasable immediately thereafter.

          (f)  The Exercise Price of the Series B Warrants shall be 
     automatically and permanently reduced by $.10 per share each if (i) the 
     Initial Registration Statement (as defined in the Dealer Registration 
     Rights Agreement) has not become effective on or prior to that date 
     which is 270 days from the Final Closing Date, (ii) the Commission shall 
     have issued a stop order suspending the effectiveness of the Initial 
     Registration Statement and the number of days stop orders have been in 
     effect, together with the number of days a notice under Section 4.1(d) 
     of the Dealer Registration Rights Agreement has been issued or required 
     to be issued, exceeds 180 days, or (iii) (A) the Company for the third 
     time, notifies or is required to notify the holders of the Warrants 
     pursuant to Section 4.1(d) of the Dealer Registration Rights Agreement, 
     or (B) a notice under such Section 4.1(d) is effective or required to be 
     effective at a time when the aggregate number of days for which all such 
     notices issued or required to be issued pursuant to such Section 4.1(d) 
     have been, or were required to be, in effect, exceeds 180 days (270 days 
     from the Final Closing Date in the case of clause (i), or the date the 
     third notice is sent or required to be sent or the date on which the 
     180-day limit is exceeded in the case of clause (ii) or (iii), is each 
     referred to herein as an "Event Date"). Additionally, the Exercise Price 
     of each Series B Warrant then outstanding shall be subject to further 
     downward adjustment in the amount of $.10 each on the same day of each 
     month following the initial Event Date (or, if there is no numerically 
     corresponding day in any such subsequent month, then on the last day of 
     such applicable subsequent month) until the Registration Statement 
     becomes effective; PROVIDED, HOWEVER, that such adjustments will, in 
     each case, cease to accrue on the date which (x) the Initial 
     Registration Statement is declared effective, with respect to the 
     adjustments for failure to be declared effective by that date which is 
     270 days from the Final Closing Date, (y) the Initial Registration 
     Statement is no longer subject to an order


                                        9

<PAGE>

     suspending the effectiveness thereof, with respect to adjustments for the 
     failure to remain effective or (z) a notice issued, or required to be 
     issued, pursuant to Section 4.1(d) of the Dealer Registration Rights 
     Agreement is no longer effective or required to be effective, with 
     respect to adjustments payable pursuant to clause (iii) above.  In no 
     event shall the Series B Warrant Exercise Price be adjusted below $1.50 
     solely due to this Section 9.1 (f).

          (g)  Whenever the number of Shares purchasable upon the exercise of a
     Warrant or the Exercise Price is adjusted as herein provided, the 
     Company shall cause to be promptly mailed to the holder by first class 
     mail, postage prepaid, notice of such adjustment or adjustments and a 
     certificate of a firm of independent public accountants selected by the 
     Board of Directors of the Company (who may be the regular accountants 
     employed by the Company) setting forth the number of Shares purchasable 
     upon the exercise of a Dealer Warrant or Series B Warrant, as the case 
     may be, and the related Exercise Price after such adjustment, a brief 
     statement of the facts requiring such adjustment and the computation by 
     which such adjustment was made.

          (h)  For the purpose of this Subsection 9.1, the term "Common 
     Stock" shall mean (i) the class of stock designated as the Common Stock 
     of the Company at the date of this Agreement or (ii) any other class of 
     stock resulting from successive changes or reclassifications of such 
     Common Stock. In the event that at any time, as a result of an 
     adjustment made pursuant to this Section 9, the holder shall become 
     entitled to purchase any securities of the Company other than shares of 
     Common Stock, thereafter the number of such other securities so 
     purchasable upon exercise of the Dealer Warrant or the Series B Warrant 
     and the Exercise Price of such securities shall be subject to adjustment 
     from time to time in a manner and on terms as nearly equivalent as 
     practicable to the provisions with respect to the Dealer Shares and 
     Series B Warrant Shares contained in this Section 9.

          (i)  Upon the expiration of any rights, options, warrants or 
     conversion privileges which caused an adjustment under this Section 9.1, 
     if such shall not have been exercised, the number of Dealer Shares and 
     Series B Warrant Shares purchasable upon exercise of the Dealer Warrants 
     and the Series B Warrants and the applicable Exercise Prices, to the 
     extent the Dealer Warrants or the Series B Warrants have not then been 
     exercised, shall, upon such expiration, be readjusted and shall 
     thereafter be such as they would have been had they been originally 
     adjusted (or had the original adjustment not been required, as the case 
     may be) on the basis of (A) the fact that the only shares of Common 
     Stock so issued were the shares of Common Stock, if any, actually


                                       10

<PAGE>

     issued or sold upon the exercise of such rights, options, warrants or 
     conversion rights and (B) the fact that such shares of Common Stock, if 
     any, were issued or sold for the consideration actually received by the 
     Company upon such exercise plus the consideration, if any, actually 
     received by the Company for the issuance, sale or grant of all such 
     rights, options, warrants or conversion rights whether or not exercised; 
     PROVIDED, HOWEVER, that no such readjustment shall have the effect of 
     increasing the applicable Exercise Prices of the Dealer Warrants or 
     Series B Warrants by an amount in excess of the amount of the adjustment 
     initially made in respect of the issuance, sale or grant of such rights, 
     options, warrants or conversion privileges.

          (j)  The Company shall have the right to reduce the exercise price 
     of any or all of the Dealer Warrants or the Series B Warrants at any 
     time and from time to time that such appears in the Company's best 
     interests to do so.

          9.2 PRESERVATION OF PURCHASE RIGHTS UPON RECLASSIFICATION.
CONSOLIDATION. ETC.  In case of any consolidation of the Company with or merger
of the Company into another corporation or in case of any sale or reconveyance
to another corporation of the property, assets or business of the Company as an
entirety or substantially as an entirety, the Company or such successor or
purchasing corporation, as the case may be, shall provide that the holder shall
have the right thereafter upon payment of the Exercise Price in effect
immediately prior to such action to purchase upon exercise of the Dealer Warrant
the kind and amount of shares and other securities and property which he would
have owned or have been entitled to receive after the happening of such
consolidation, merger, sale or conveyance had the Dealer Warrant been exercised
immediately prior to such action.  Such agreement shall provide for adjustments,
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 9. The provisions of this Subsection 9.2 shall
similarly apply to successive consolidations, mergers, sales or conveyances.

          9.3 PAR VALUE OF COMMON STOCK.  Before taking any action which would
cause an adjustment reducing the Exercise Price below the then par value of the
shares of Common Stock issuable upon exercise of the Dealer Warrant, the Company
will take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
non-assessable shares of Common Stock at such adjusted Exercise Price.

          9.4  STATEMENT ON WARRANT CERTIFICATES.  Irrespective of any
adjustments in the Exercise Price or the number of securities purchasable upon
the exercise of the Dealer Warrant or Series B Warrant, the Warrant certificate
or certificates theretofore or thereafter issued may continue to express the
same


                                       11

<PAGE>

price and number of securities as are stated in the similar Warrant certificates
initially issuable pursuant to this Agreement.  However, the Company may at any
time in its sole discretion (which shall be conclusive) make any change in the
form of the Warrant certificate that it may deem appropriate and that does not
affect the substance thereof; and any Warrant certificate thereafter issued,
whether upon registration or transfer of, or in exchange or substitution for, an
outstanding Warrant certificate, may be in the form so changed.

          9.5 PRIOR NOTICE TO WARRANT HOLDERS.  In the event that at any time
prior to the expiration of the Warrants and prior to their exercise, any of the
following events shall occur:

          i.   any action which would require an adjustment
               pursuant to Sections 9.1 or 9.2; or

          ii.  a dissolution, liquidation or winding up of the
               Company (other than in connection with a
               consolidation, merger or sale of its property,
               assets and business, as an entirety) shall be
               proposed;

then, in any such event, the Company shall cause at least twenty (20) days'
prior written notice to be mailed to each Warrant Holder at the address of such
holder shown on the books of the Company.  The notice shall also specify the
date on which the books of the Company shall close or a record be taken for such
stock dividend, distribution or subscription rights, or the date on which such
reclassification, reorganization, consolidation, merger, sale, transfer,
disposition, liquidation, dissolution, winding up, or dividend, as the case may
be, shall take place, and the date of participation therein by the holders of
shares of Common Stock if any such date is to be fixed, and shall also set forth
such facts with respect thereto as shall be reasonably necessary to indicate the
effect of such action on the rights of the Warrant Holder.

          9.6 DISPUTES.  In the event that there is any dispute as to the
computation of the Exercise Price or the number of shares of Common Stock or
other securities required to be issued upon the exercise of the Warrants, the
Company will retain an independent and nationally recognized accounting firm to
conduct an audit of the computations pursuant to the terms hereof involved in
such dispute, including the financial statements or other information upon which
such computations were based.  The determination of such nationally recognized
accounting firm shall, in the absence of manifest error, be binding.  If there
shall be a dispute as to the selection of such nationally recognized accounting
firm, such firm shall be appointed by the American Institute of Certified Public
Accountants ("AICPA") if willing, otherwise the American Arbitration Association
("AAA"). If the Exercise Price or number of shares of Common Stock as


                                       12


<PAGE>

determined by such accounting firm is one percent or more higher or lower than
the calculations thereof computed by the Company, the expenses of such
accounting firm and, if any, of AICPA and AAA, shall be borne completely by the
Company.  In all other cases, they shall be borne by the complaining Warrant
Holders, as applicable.

          9.7 CURRENT MARKET PRICE.  For the purpose of this Section 9, the term
"Current Market Price" shall mean (i) if the Common Stock is traded in the over-
the-counter market or on the National Association of Securities Dealers, Inc.
Automated Quotations System ("NASDAQ"), the average per share closing bid prices
of the Common Stock on the 20 consecutive trading days immediately preceding the
date in question, as reported by NASDAQ or an equivalent generally accepted
reporting service, or (ii) if the Common Stock is traded on a national
securities exchange, the average for the 20 consecutive trading days immediately
preceding the date in question of the daily per share closing prices of the
Common Stock on the principal stock exchange on which it is listed, as the case
may be. The closing price referred to in clause (ii) above shall be the last
reported sales price or in case no such reported sale takes place on such day,
the average of the reported closing bid and asked prices, in either case on the
national securities exchange on which the Common Stock is then listed.

     10.  NOTICES.

          All notices, demands, elections, opinions or requests (however
characterized or described) required or authorized hereunder shall be deemed
given sufficiently if in writing and sent by registered or certified mail,
return receipt requested and postage prepaid, or by confirmed telex, telegram,
facsimile transmission or cable to, in the case of the Company:

                     DEALER REGISTRATION RIGHTS AGREEMENT

     This Registration Rights Agreement (this "AGREEMENT") is made and entered
into on September 4, 1996, by and among SERACARE, Inc., a Delaware corporation
(the "COMPANY"), and those individuals and entities (the "PURCHASERS")
purchasing warrants (the "DEALER WARRANTS") pursuant to the Dealer Warrant
Agreement, dated as of the date hereof, by and between the Company and the
Purchasers, which Dealer Warrants entitle the Purchasers to acquire an
aggregate of 34,500 Dealer Units at an exercisable price of $3.00 per Dealer
Unit.  Each Dealer Unit consists of two shares (the "SHARES") of the Company's
Common Stock, with $0.001 par value (the "COMMON STOCK"), and a warrant to
purchase one share of Common Stock exercisable at $2.75 (the "B WARRANTS").

     In order to induce the Agent to enter into the Placement Agency Agreement
relating to the offering of the Units (the "PLACEMENT AGENCY AGREEMENT"), the
Company has agreed to provide the registration rights set forth in this
Agreement.  Capitalized terms used herein without definition shall have the
meaning set forth in the Placement Agency Agreement.

     The parties hereby agree as follows:

     1.   DEFINITIONS.

          (a)  "REGISTRABLE SECURITIES" means each of the following: (i) the 
shares of Common Stock included in the Dealer Units issuable upon exercise of 
the Dealer Warrants (the "DEALER UNIT COMMON STOCK"), whether or not such 
Common Stock has been issued and (ii) the shares of Common Stock issuable 
upon exercise of the B Warrants, whether or not such B Warrants or the Common 
Stock underlying such B Warrants have been issued; provided that Registrable 
Securities shall not include any shares which (x) can be publicly resold by 
the holders thereof without registration under the Securities Act of 1933, as 
amended (the "ACT") or the availability of an exemption thereunder, (y) which 
are currently registered under an effective registration statement, or (z) 
which have been sold to the public or in a private transaction in which the 
transferor's rights under this agreement are not assigned.

          (b)  "HOLDER(S)" means (i) the record owners of Registrable 
Securities (including the record owners of the Dealer Warrants and Series B 
Warrants issued pursuant to Section 1(g) of the Placement Agency Agreement); 
and (ii) the record owners of Registrable Securities (including the record 
owners of the Dealer Warrants and Series B Warrants issued pursuant to

registration rights have been transferred in accordance with Section 10(c)

                                       1

<PAGE>

     2.   MANDATORY AND DEMAND REGISTRATION RIGHTS.

           (a)  MANDATORY REGISTRATION RIGHTS.  The Company will use its best 
efforts to file with the Securities and Exchange Commission (the 
"COMMISSION") and to cause to become effective no later than that date which 
is 270 days from the Final Closing (such day is referred to herein as the 
"EFFECTIVE DATE"), a registration statement (the "INITIAL REGISTRATION 
STATEMENT") under the Act for the offering and sale of the Registrable 
Securities and the securities registrable pursuant to Section 2(a) of the 
Registration Rights Agreement, dated September 4, 1996, by and among the 
Company and certain purchasers of Units of the Company (the "PURCHASER 
REGISTRATION RIGHTS AGREEMENT").  The Company shall use its best efforts to 
keep such Initial Registration Statement effective for the period required 
under the Purchaser Registration Rights Agreement.

           (b)  DEMAND REGISTRATION RIGHTS.  If the Company has failed to 
register the Registrable Securities in accordance with Section 2(a) above, or 
if such Initial Registration Statement is not then effective, and the 
majority of the Holders of Registrable Securities shall so request in 
writing, but no more than six (6) years after the final closing of the 
offering of the Units, the Company shall use its best efforts to effect the 
registration of the Registrable Securities under the Act (the "DEMAND 
REGISTRATION STATEMENT"). This right may be exercised at any time during the 
aforesaid period, but may be exercised one time only.  In the event of such a 
demand, the Company shall, as expeditiously as practicable, use its best 
efforts to effect the registration under the Act of the Registrable 
Securities, but in no event shall such Demand Registration Statement become 
effective later than 150 days after such demand (the ""EFFECTIVE DATE").  
Further, the Company shall use its best efforts to keep the Demand 
Registration Statement effective throughout the 180 day period commencing on 
the Effective Date.  (The period during which the Demand Registration 
Statement is in effect shall hereinafter be referred to as the "REGISTRATION 
PERIOD".)  Only the days during which such Demand Registration Statement is 
effective shall be counted for the purpose of the 180 day period referred to 
above in this Section 2(b).  The Company agrees to promptly notify all 
Holders of the (formerly) Registrable Securities upon the effectiveness 
thereof.

           (c)  AMENDMENTS TO DEMAND REGISTRATION STATEMENT.  The Company 
further agrees, if necessary, to supplement or make amendments to the Demand 
Registration Statement and any prospectus contained therein, if required by 
the Registration Statement form utilized by the Company or by the 
instructions applicable to such registration form or by the Act or the rules 
and regulations thereunder, and the Company agrees to furnish copies of each 
Demand Registration Statement, prospectus, supplement or amendment prior to 
or concurrently with its being used and/or filed with the Securities and 
Exchange Commission


                                       2

(the "Commission") to the Holders of Registrable Securities making the demand
specified under subsection (b) of this Section 2.

           (d)  EARNINGS STATEMENT.  The Company will make available to its 
security holders, as soon as reasonably practicable, an earnings statement 
covering a period of twelve months, commencing on the first day of the fiscal 
quarter next succeeding the effective date of each sale of any Registrable 
Securities pursuant to the Demand Registration Statement, which earnings 
statement shall satisfy the provisions of Section 11(a) of the Act.

           (e)  The Company will pay all Registration Expenses (as hereinafter
defined) incurred in connection with the Company's registration obligations
pursuant to this Section 2.

           (f)  The Company agrees to take whatever actions are reasonably 
deemed necessary by the Agent in order to assist the Purchasers and their 
agents when selling securities of the Company in complying with Rule 15c6-1 
of the Securities Exchange Act of 1934, as amended.

     3.   PIGGYBACK REGISTRATION.

           (a)  If, prior to the effectiveness of the Initial Registration 
Statement or at any time the Initial Registration Statement or a Demand 
Registration Statement is not effective, any Registrable Securities continue 
to be Registrable Securities, each time that the Company shall propose the 
registration under the Act of any shares of Common Stock of the Company, 
other than a registration relating to employee benefit plans, or a corporate 
reorganization or other transactions under Rule 145, notice of such proposed 
registration stating the total number of shares proposed to be the subject of 
such registration shall be given to the Holders of Registrable Securities.  
The Company will use its best efforts to include in any registration 
statement filed with the Commission with regard to such proposed registration 
the number of Registrable Securities specified in writing by any such Holders 
to it within 20 days after receipt of said notice, provided that any Holders 
of any Warrant exercises such of his Warrants within 20 days after receipt of 
said notice as is necessary to have included in the registration statement 
the shares of Common Stock so specified by him.  Any Holder who participates 
in the public offering pursuant to such registration statement shall be 
entitled to all the benefits of this Agreement in connection with any 
registration hereunder, except as otherwise provided in this Section 3.  The 
right to registration provided in this Section is in addition to and not in 
lieu of the registration rights provided in Section 2 hereof.

           (b)  All Registration Expenses, as hereinafter defined, and any
transfer taxes incurred by the Holders of Registrable


                                       3

<PAGE>

Securities, in connection with the offering of securities of the Company 
pursuant to any registration statement filed pursuant to this Section 3, 
whether or not such registration statement becomes effective under the Act, 
shall be borne by the Company. Such Holders shall pay all out-of-pocket 
expenses incurred by them with respect to the registration and sale of the 
shares of Registrable Securities owned by them and included in such 
registration statement. Notwithstanding the foregoing, in the event the 
Company fails to file and cause to become effective, and thereafter maintain 
the effectiveness of, an Initial Registration Statement as provided for in 
Section 2 above, all Registration Expenses shall be borne by the Company.

           (c)  Notwithstanding anything to the contrary in this Section 3, the
Holders of the Registrable Securities shall not be entitled to include in any
registration statement filed pursuant to this Section 3 Registrable Securities
to the extent such inclusion would materially and adversely affect the proposed
distribution of the Common Stock in respect of which registration was originally
to be effected.  The number of Registrable Securities to be included by each
Holder shall be allocated in accordance with Section 3(e), below.

           (d)  The piggyback registration rights provided in this Section 3 
may be exercised by the Holders of Registrable Securities from time to time 
with respect to any or all registrations under the Act of Common Stock of the 
Company in accordance with the provisions of this Section 3.

           (e)  In any circumstances in which all of the Registrable 
Securities requested to be included in a registration cannot be so included 
as a result of limitations on the aggregate number of shares of Registrable 
Securities that may be so included, the number of shares of Registrable 
Securities that may be so included shall be allocated among the Holders of 
Registrable Securities pro rata on the basis of the number of shares of 
Registrable Securities that would be held by such Holders, assuming exercise 
of the Warrants; provided, however, that if any Holder does not request 
inclusion of the maximum number of shares of Registrable Securities allocated 
to him pursuant to the above-described procedure, then the remaining portion 
of his allocation shall be reallocated among those requesting Holders whose 
allocations did not satisfy their requests pro rata on the basis of the 
number of shares of Registrable Securities which would be held by such 
Holders, assuming exercise, and this procedure shall be repeated until all of 
the shares of Registrable Securities which may be included in the 
registration have been so allocated.  Such allocation shall not operate to 
reduce the aggregate number of Registrable Securities permitted to be 
included in such registration.

     4.   REGISTRATION PROCEDURES

     4.1  In connection with each registration provided for in Sections 2 or 3
hereof, the Company will as expeditiously as practicable:

           (a)  furnish to each seller of Registrable Securities, the prospectus
included in such registration statement and amendments thereto and such other
documents as such seller may reasonably request in order to facilitate the
disposition of the Registrable Securities owned by such seller;

           (b)  use its best efforts to register or qualify the Registrable 
Securities included in any registration statement filed in accordance with 
Sections 2 or 3 hereof under such securities or blue sky laws of such 
jurisdictions as any such seller reasonably requests and do any and all other 
acts and things which may be reasonably necessary or advisable to enable such 
seller to consummate the disposition in such jurisdictions of the Registrable 
Securities owned by such seller; provided that the Company will not be 
required to (i) qualify generally to do business in any jurisdiction where it 
would not otherwise be required to qualify but for this paragraph (b), (ii) 
subject itself to taxation in any such jurisdiction by reason of such 
registration or qualification of any Registrable Securities, or (iii) consent 
to general service of process in any such jurisdiction;

           (c)  use its best efforts to cause the Registrable Securities 
covered by any such registration statement to be registered with or approved 
by such other governmental agencies or authorities as may be necessary by 
virtue of the business and operations of the Company to enable the seller or 
sellers thereof to consummate the disposition of such Registrable Securities; 

           (d)  notify each seller of such Registrable Securities, at any time
when a prospectus relating thereto is required to be delivered under the Act, of
the happening of any event as a result of which the prospectus included in any
such registration statement contains an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, and prepare a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers 
of such Registrable Securities, such prospectus will not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading;

           (e)  use its best efforts to cause all such Registrable Securities 
to be listed on each securities exchange on which similar securities issued 
by the Company are then listed, provided that the applicable listing 
requirements are satisfied;


                                       5

<PAGE>

           (f)  make available for inspection by any seller of such 
Registrable Securities, any underwriter participating in any disposition 
pursuant to any such registration statement, and any attorney, accountant or 
other agent retained by any such seller or underwriter (collectively, the 
"INSPECTORS"), all financial and other records, pertinent corporate documents 
and properties of the Company (collectively, the "RECORDS") as shall be 
reasonably necessary to enable them to exercise their due diligence 
responsibility, and cause the Company's officers, directors and employees to 
supply all information reasonably requested by any such inspector in 
connection with such registration statement.  All such records shall be 
deemed to be confidential and each seller shall cause the Inspectors to keep 
the information therein confidential and not disclose it to third parties 
unless (i) the disclosure of such Records is necessary to avoid or correct a 
misstatement or omission in the registration statement, (ii) the release of 
such Records is ordered pursuant to regulatory reporting requirements or a 
subpoena or other order from a court of competent jurisdiction or (iii) the 
filing of such Records as exhibits to such registration statement is required 
by the Commission's rules and regulations.  Each seller of such Registrable 
Securities agrees that it will, upon learning that disclosure of such Records 
is sought in a court of competent jurisdiction, give notice to the Company 
and allow the Company, at the Company's expense, to undertake appropriate 
action to prevent disclosure of the Records;

           (g)  in the event the sale of such Registrable Securities is 
pursuant to an underwritten offering, use its best efforts to obtain a 
"comfort" letter from the Company's independent public accountants in 
customary form and covering such matters of the type customarily covered by 
"comfort" letters as the underwriters reasonably request; and

           (h)  otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission.

      4.2  The Company may require, as a condition to its obligations under this
Agreement, that each seller of Registrable Securities registered pursuant to
Sections 2 or 3 hereof furnish to the Company such information regarding the
distribution of such securities as the Company may from time to time reasonably
request in writing.

      4.3  Each seller of Registrable Securities registered pursuant to Sections
2 or 3 hereof agrees that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 4.1(d) hereof, such
seller will forthwith discontinue disposition of such Registrable Securities
pursuant to the registration statement covering such securities until such
seller's receipt of the copies of the supplemented or amended prospectus
contemplated by Section 4.1(d) hereof, and, if so directed by the Company, such
seller will deliver to the


                                       6

<PAGE>

Company (at the Company's expense) all copies, other than permanent file copies
then in such sellers possession, of the prospectus covering such Registrable
Securities that is current at the time of receipt of such notice.

     5.   REGISTRATION EXPENSES

          Registration Expenses shall be borne as set forth in Sections 2 and 3
hereof.  Registration Expenses ("Registration Expenses") shall consist of all
expenses incidental to the Company's performance of or compliance with this
Agreement, including without limitation all registration and filing fees, fees
and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel in connection with blue sky
qualifications of the Registrable Securities), printing expenses, messenger and
delivery expenses, internal expenses (including, without limitation, all
salaries and expenses of the Company's officers and employees performing legal
or accounting duties), the fees and expenses incurred in connection with the
listing of such securities on each securities exchange on which similar
securities issued by the Company are then listed, and fees and disbursements of
counsel for the Company and of its independent certified public accountants
(including the expenses of any special audit or "comfort" letters required by or
incident to such performance), securities acts liability insurance (if the
Company elects to obtain such insurance), the reasonable fees and expenses of
any special experts retained by the Company in connection with any registration
of Registrable Securities.

     6.   INDEMNIFICATION: CONTRIBUTION

           (a)  INDEMNIFICATION BY THE COMPANY.  The Company agrees to 
indemnify, to the full extent permitted by law, each seller of Registrable 
Securities, its officers and directors and each person who controls such 
seller (within the meaning of the Act) against all losses, claims, damages, 
liabilities and expenses caused by any untrue or alleged untrue statement of 
material fact contained in any registration statement, prospectus or 
preliminary prospectus or amendment or supplement thereto or any omission or 
alleged omission to state therein a material fact required to be stated 
therein or necessary to make the statements therein, in the light of the 
circumstances under which they were made not misleading, and the Company will 
reimburse legal or other expenses reasonably incurred by such seller in 
investigating or defending any claims relating to or arising from such untrue 
statements or omissions, in all cases except insofar as such are caused by 
(i) statements or omissions made in reliance upon or contained in any 
information with respect to such seller furnished in writing to the Company 
by such seller expressly for use therein or (ii) such seller's failure to 
deliver a copy of the final prospectus as then amended or supplemented after 
the Company has furnished such seller with a 


                                       7

<PAGE>

sufficient number of copies of the same, but only if delivery of same is
required by law and if same would have cured the defect giving rise to any such
loss, claim, damage, liability or expense.  Such indemnification shall be
effective irrespective of any investigation by any seller.

           (b)  INDEMNIFICATION BY SELLERS OF REGISTRABLE SECURITIES.  In 
connection with any registration statement relating to a sale of Registrable 
Securities, each seller thereof will furnish to the Company in writing such 
information and affidavits with respect to such seller as the Company 
reasonably requests for use in connection with any such registration 
statement (or prospectus contained therein) and will indemnify, to the extent 
permitted by law, the Company, its directors, its officers who sign the 
registration statement and each person who controls the Company (within the 
meaning of the Act) against any losses, claims, damages, liabilities and 
expenses resulting from any untrue or alleged untrue statement of material 
fact or any omission or alleged omission of a material fact required to be 
stated in such registration statement or prospectus or any amendment thereof 
or supplement thereto or necessary to make the statements therein, in the 
light of the circumstances under which they were made, not misleading, in 
each case to the extent, but only to the extent, that any such loss, 
liability, claim, damage or expense arises out of or is based upon any such 
untrue statement or alleged untrue statement or omission or alleged omission 
made therein in reliance upon and in conformity with such written information 
or affidavits relating to such seller furnished to the Company by such seller 
expressly for use therein.

           (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS.  Any person entitled 
to indemnification hereunder agrees to give prompt written notice to the 
indemnifying party after the receipt by such person of any written notice of 
the commencement of any action, suit, proceeding or investigation or threat 
thereof made in writing for which such person will claim indemnification or 
contribution pursuant to this Agreement and, unless in the reasonable 
judgment of such indemnified party a conflict of interest may exist between 
such indemnified party and the indemnifying party, shall permit the 
indemnifying party to assume the defense of such claim with counsel 
reasonably satisfactory to such indemnified party.  If the indemnifying party 
is not entitled to, or elects not to, assume the defense of a claim, it will 
not be obligated to pay the fees and expenses of more than one counsel for 
the indemnified party with respect to such claim. The indemnifying party will 
not be subject to any liability for any settlement made without its consent.  
Failure of notice by a seller of Registrable Securities entitled to 
indemnification hereunder will not relieve the Company of its obligations 
under this Section 6 unless the Company is actually prejudiced thereby.


                                       8

<PAGE>

           (d)  CONTRIBUTION

                (i)  If the indemnification provided for in this Section 6 
from the indemnifying party is unavailable to an indemnified party hereunder 
in respect of any losses, claims, damages, liabilities or expenses referred 
to therein, then the indemnifying party, in lieu of indemnifying such 
indemnified party, shall contribute (on the basis of relative fault) to the 
amount paid or payable by such indemnified party as a result of such losses, 
claims, damages, liabilities or expenses.  The relative fault of such 
indemnifying and indemnified parties shall be determined by reference to, 
among other things, whether any action in question, including any untrue or 
alleged untrue statement of a material fact or omission or alleged omission 
to state a material fact, has been made by, or relates to information 
supplied by, such indemnifying or indemnified parties, and the parties' 
relative intent, knowledge, access to information and opportunity to correct 
or prevent such action.  The amount paid or payable by a party as a result of 
the losses, claims, damages, liabilities and expenses referred to above shall 
be deemed to include, subject to the limitations set forth in Section 6(c), 
any legal or other fees or expenses reasonably incurred by such party in 
connection with any investigation or proceeding.  Notwithstanding the 
provisions of this Section 6(d)(i), in no case shall any seller of 
Registrable Securities be liable or responsible for any amount in excess of 
the net proceeds received by such seller from the sale of the Registrable 
Securities of such seller which are included in any registration statement 
contemplated by this Agreement.

               (ii)  No person guilty of fraudulent misrepresentation (within 
the meaning of Section 11(f) of the Act) shall be entitled to contribution 
from any person who was not guilty of such fraudulent misrepresentation.

             (iii)  If indemnification is available under this Section 6, the 
indemnifying parties shall indemnify each indemnified party to the full 
extent provided in Sections 6(a) and (b) without regard to the relative fault 
of said indemnifying party or indemnified party.

     7.   PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

           (a)  No Holder of Registrable Securities may participate, pursuant 
to Section 3 hereof, in any underwritten offering of Common Stock of the 
Company, notice of which is given pursuant to Section 3 hereof, unless such 
owner (i) agrees to sell its Registrable Securities pursuant to the 
underwriting arrangements approved by the Company and its counsel and (ii) 
completes and executes all questionnaires, powers of attorney, indemnities, 
underwriting agreements and other documents reasonably required under the 
terms of such underwriting arrangements.


                                       9

<PAGE>

           (b)  The Company shall have no obligation under Section 3 to the 
extent that any underwriter in connection with the registered public offering 
reasonably notifies the Company of its determination that the Registrable 
Securities or a portion thereof should be excluded therefrom.  In the event 
that a portion is to be excluded, the number of Registrable Securities to be 
included by each Holder shall be allocated in accordance with Section 3(e), 
above.

     8.   RULE 144

          The Company covenants that it will timely file the reports required to
be filed by it under the Act and the Exchange Act and the rules and regulations
adopted by the Commission thereunder, and it will take such further action as
any record owner of Registrable Securities may reasonably request, all to the
extent required from time to time to enable such owner to sell Registrable
Securities without registration under the Act within the limitation of the
exemptions provided by (a) Rule 144 under the Act, as such Rule may be amended
from time to time, or (b) any similar rule or regulation hereafter adopted by
the Commission.  Upon the request of any record owner of Registrable Securities,
the Company will deliver to such owner a written statement as to whether it has
complied with such requirements.

     9.   TERMINATION

          This Agreement shall terminate on the sixth anniversary of the final
closing (as that term is defined in the Confidential Private Placement
Memorandum dated June 1, 1996).  The provisions of Section 6 hereof shall
survive such termination.

     10.  MISCELLANEOUS

the provisions of this Agreement may not be amended, modified or 
supplemented, and waivers or consents to departures from the provisions

Securities then outstanding affected by such amendment, modification,

written notice at the time of or within a reasonable time after said transfer 
or assignment, stating the name and address of the transferee or assignee and 
identifying the securities with respect to which such registration rights are 
being transferred or assigned, and, provided further, that the transferee or 
assignee of such rights assumes in writing the obligations of such transferor 
under this agreement.

           (d)  COUNTERPARTS.  This Agreement may be executed in any number 
of counterparts and by the parties hereto in separate counterparts, each of

TO THE HONORABLE ALAN M. AHART, UNITED STATES BANKRUPTCY JUDGE; THE UNITED 
STATES TRUSTEES; CREDITORS OF THE ABOVE-NAMED DEBTORS AND ALL OTHER

         This Motion is made on the grounds that the Plan meets all of the

                                     ------------
 
       This memorandum and the materials filed concurrently as exhibits 
hereto are submitted for the purpose of assisting the Court at arriving at a 
fully informed judgment on the issue of whether the plan is worthy of 
confirmation.  Since its inception, this reorganization proceeding has been a 
great challenge to all involved in it.  The final act of the reorganization 
process is now at hand, and it remains for this Court to determine whether 
the Plan meets the statutory requirements for confirmation.  This memorandum 
attempts to make comprehensive analysis of the economic, financial and legal 
issues placed before the Court in this case.
                
                                         II.
                                           
                       ABBREVIATED HISTORY OF THESE PROCEEDINGS
                       ----------------------------------------

These proceedings were commenced January 7, 1994 by the filing of voluntary 
petitions by each of the Debtors under chapter 11 of the Bankruptcy Code.  
Early in the case the Court entered an order approving joint administration 
of all these cases thereby avoiding duplication of costs and expenses.        
    
     By order entered September 21, 1994 the Bankruptcy Court authorized ABI 
to obtain up to $4.5 million in credit through the issuance of Debtors' 
Notes. The Debtors filed a plan

           

                                      -3-

based on such financing.  ABI initially attempted to place the Notes through 
Relco Corporation ("Relco"), an investment banking firm primarily engaged in 
restructuring and financing companies in chapter 11.  Relco was unable to 
place the Notes, and ABI was forced to turn to other sources and withdraw the 
Plan based on financing from Relco.

     More recently, ABI received a best efforts commitment from First Equity 
Capital Corporation ("First Equity") to place $1.2 million in Debtors' Notes 
with its clients, which will net approximately $1 million to ABI.  Based on 
this new financing source, the Debtors filed their Second Amended Joint Plan 
on October 26, 1995.  In order to meet certain objections to the Second 
Amended Joint Plan and its accompanying disclosure statement, the Debtors 
filed their Third Amended Joint Plan of Reorganization (the "Plan") and 
accompanying disclosure statement.  The disclosure statement for the Plan was 
approved by the Court by order entered December 28, 1996 pursuant to the 
hearing held on December 6, 1995 as containing adequate information, it was 
disseminated to creditors and other interested parties together with the 
ballots and certain other materials on December 8, 1995.  A copy of the order 
approving the disclosure statement for the Plan is attached hereto as Exhibit 
"A"

    As of the date of the filing of this Motion, the $1.2 million in Debtors' 
Notes have been substantially subscribed.  As is shown more fully in the 
disclosure statement to the Plan, full subscription of $1.2 million in 
Debtors' Notes will yield sufficient cash to fund the Plan.

    Meanwhile, CVD Financial Corporation ("CVD") obtained relief from stay to 
foreclose on its security effective January 2, 1996 by order entered August 
25, 1995.  CVD is the major creditor of the Debtors and is secured by the 
assets of each of the Debtors and the stock of AVRE and Binary.  On November 
29, 1995 the Debtors filed a complaint against CVD seeking to enjoin CVD from 
proceeding with foreclosure until after the confirmation hearing on the Plan. 
 Hearing on a preliminary injunction in connection with the complaint 
scheduled for December 20, 1995 has been continued to January 17, 1996, and 
CVD has agreed that it will not foreclose on its security until after the 
hearing on the preliminary injunction.

                        THE DISCLOSURE STATEMENT AND THE PLAN
                                           
    As noted above, on November 27, 1995 the Debtors filed the Plan with the 
Court.  Also on November 27, 1995 the Debtors filed the Disclosure Statement 
with respect to the Plan, which Disclosure Statement was approved by this 
Court's order entered December 28, 1995. 

    The Debtors' management worked closely with bankruptcy counsel to prepare 
the Disclosure Statement, which the Court has ruled contains adequate 
information regarding the Plan.  After obtaining approval of the Disclosure 
Statement, the Debtors caused materials consisting of the Disclosure 
Statement, the form of ballots, the Plan, the Notice of Hearing to Consider 
Confirmation of the Plan and Time Fixed for Filing Acceptance or

                 

                                      -5-

Rejection of the Plan, and a letter from counsel to the Official Creditors 
Committee to be disseminated to creditors.  A copy of the materials so 
disseminated is filed herewith as Exhibit "B."

    The Disclosure Statement is quite complete, describing the history and 
nature of the Debtors and the reorganization proceedings and describing the 
management, business and finances of the Debtors. The Disclosure Statement 
also summarizes the Plan, including a forecast of post-reorganization 
operations, and has a copy of the Plan attached as an exhibit.  The 
Disclosure Statement contains the liquidation, implementation and feasibility 
analysis that will serve as a cornerstone for showing that the Plan complies 
with the confirmation requirements of the Code discussed below.  Rather than 
repeat material contained is the Disclosure Statement, this memorandum 
incorporates by reference the discussion in the Disclosure Statement.

                                CONFIRMATION CRITERIA
                                           
     In order to be confirmed, the Plan must comply with all of the 
requirements set forth in 11 U.S.C. sections 1129(a)(1)-(13).  This memorandum 
demonstrates conclusively that the Plan complies with each of the 
requirements set forth in the Code and should therefore be confirmed by this 
Court.

      A.   THE PLAN COMPLIES WITH THE APPLICABLE PROVISIONS 
           OF CHAPTER 11 (SECTION 1129(a)(1)).      

     Section 1129(a)(1) of the Code requires a plan to comply with the 
applicable provisions of Chapter 11.  In general, a plan must comply with 
sections 1121 and 1123 of the Code.  IN RE SULLIVAN, 26 B.R. 677, 678 (Bankr. 
W.D.N.Y. 1982).
                 
           1.   SECTION 1122.
        
            Section 1122 of the Code relates to classification of claims or 
interests. Section 1122 (a) requires a plan to place a claim or interest in a 
particular class only if the claim or interest is substantially similar to 
other claims or interests of such class.  Article II of the Plan designates 
classes of claims and interests.                  

     Class 1 consists of all allowed unsecured claims entitled to priority 
under Section 507(a)(3), (4), (5), (6) or (7) of the Code.  Since these 
claims are all entitled to priority and all receive identical treatment under 
the Plan, and since this class is unimpaired under Section 1124(3) of the 
Code because each holder of a class 1 claim will receive cash on the 
effective date of the plan equal to the allowed amount of the claim, it is 
not necessary to classify separately the various priority claims into 
different classes.                  

     Class 2 consists of the allowed secured claim of CVD, estimated at 
approximately $1.6 million.  The Plan provides that the Class 2 claimant will 
be paid $600,000 cash on the effective date, the balance to be amortized and 
paid over four years with interest of 14% per annum on the unpaid balance.  A 
copy of the

         

                                      -7-

<PAGE>

proposed note to be given CVD is attached hereto as Exhibit "C" and is
incorporated herein by this reference.  CVD shall retain any valid security
interest it holds for its claim.

                 Class 3 consists of all allowed unsecured claims against 
ABI. Pursuant to Section 4.4 of the Plan, holders of Class 3 Claims will 
share in the distribution of the balance remaining from $200,000 cash after 
payment of Class 5 and Class 6 Claims therefrom up to a maximum payment of 
Class 3 Claims of $.10 cash for each claim dollar.  Holders of Class 3 Claims 
will also share 10,000 shares of Reorganized ABI common stock and 50% of any 
net affirmative recovery received by Debtors on account of any avoidable 
transfers.

    Class 4 consists of holders of unsecured Notes of ABI. Holders of 
unsecured Notes shall receive 105,275 shares of common stock of reorganized 
ABI.

    Class 5 consists of all allowed unsecured claims against AVRE. Pursuant 
to Section 4.6 of the Plan, holders of Class 5 Claims shall receive $.80 for 
each claim dollar in cash as soon as practicable after the effective date.

    Class 6 consists of all allowed unsecured claims against Binary pursuant 
to Section 4.7 of the Plan, creditors of Binary holding unsecured claims 
shall receive $.80 for each claim dollar in cash as soon as practicable after 
the effective date.

    Class 7 consists of preferred and common equity interests of ABI. 
Pursuant to Section 4.8 of the Plan, on the effective date all preferred and 
common equity interests of ABI shall be deemed cancelled, annulled and 
terminated, and the

                                      -8-

<PAGE>

holders of such interests shall receive no distribution under the Plan on 
account of their interests in such class.

    Class 8 consists of the holder of the issued and outstanding common stock 
of AVRB and Binary.  Pursuant to Section 4.a of the Plan, the holder of such 
stock, ABI, shall retain all such interests.
                 
    2.   SECTION 1123.

    A plan must also comply with the requirements of Section 1123 of the 
Code.  Subsection (a) of Section 1123 sets forth seven mandatory 
requirements. Under paragraph one, a plan must designate classes of claims 
other than claims of a kind specified in paragraphs 1, 2 and 8 of 
Section 507(a).  Article II of the Plan designates classes of claims and 
interests in accordance with this requirement.  Claims of the kind specified in
paragraphs 1, 2 and 8 of Section 507(a) are not classified and are treated in 
Article III of the Plan.

    Paragraph 2 of Section 1123(a) requires that a plan specify any class of 
claims or interests that is not impaired under the plan.  Article V of the 
Plan specifies classes of claims and interests that are not impaired under 
the plan thereby satisfying this requirement.

    Paragraph 3 of Section 1123(a) requires that a plan specify the treatment 
of any class of claims or interests that is impaired under the Plan. Article 
IV of the Plan indicates the treatment of the impaired classes of claims and 
interests under the Plan.

             

                                      -9-

<PAGE>

    Paragraph 4 of Section 1123(a) requires that a plan provide the same 
treatment for each claim or interest of a particular class unless the holder 
of particular claim or interest agrees to less favorable treatment of such 
particular claim or interact.  Articles III and IV of the Plan each specify 
identical treatment of all claims and interests in a various class unless a 
holder agrees to a different or a lees favorable treatment.

    Paragraph 5 of Section 1123(a) requires that a plan provide adequate 
means for the execution of the plan.  Article VII of the Plan provides the 
means for the implementation and execution of the plan, including continued 
business operations of the Debtors' entities and the borrowing of up to 
$1,175,000 by means of Debtors' Notes.

    Paragraph 6 of Section 1123(a) specifies that a plan must provide for the 
inclusion in the charter of the debtor of a provision prohibiting the 
issuance of non-voting equity securities and providing, as to the several 
classes of securities possessing voting power, an appropriate distribution of 
such power among such classes.  Article X of the Plan, which provides for the 
amendment to charter documents of the Debtors, is consistent with these 
requirements.  Furthermore, the Amendment to the Plan filed contemporaneously 
herewith and attached hereto as Exhibit 'D' specifies that the Reorganized 
Debtor shall adopt an amendment to its Articles of Incorporation that shall 
contain provisions that prohibit the issuance of nonvoting equity securities.

                                      -10-
<PAGE>

    Paragraph 7 of Section 1123(a) requires that a plan contain only 
provisions that are consistent with the interests of creditors and equity 
security holders and with public policy with respect to the manner of 
selection of any officer, director or trustee under the plan, and any 
successor to such officer, director or trustee.  The Plan does not propose to 
alter the rights of shareholders with respect to the election of directors in 
accordance with applicable law.  The exercise of voting rights under 
applicable law is consistent with the interests of creditors and equity 
security holders and with public policy.

    Subsection (b) of Section 1123 specifies five permissive provisions that 
may be included in the plan. Paragraph 1 of Section 1123(b) provides that a 
plan may impair or leave unimpaired any class of claims, secured or 
unsecured, or of interests.  The plan does so in Article IV.

    Paragraph 2 of Section 1123(b) specifies that, subject to Section 365 of 
the Code, a plan may provide for the assumption or rejection of any executory 
contract or unexpired lease of the Debtors not previously rejected.  Article 
IX of the Ply does so. The Debtors, by means of this Notice, request as order 
of the Court assuring the following executory contracts consistent with 
Article IX of the Plan:

    (1)  Leases of real property for the following
    locations:

         a)   611 North Las Vegas Boulevard, Las Vegas,
              Nevada;
         b)   1174 Fort Campbell Boulevard, Clarksville,
              Tennessee;

                                      -11-

<PAGE>

         c)   129 and 141 North Spruce, Colorado Springs,
              Colorado; and
    
         d)   411 and 413 West 4th Street, Pueblo,
              Colorado.

    (2)  Contracts for sale of source plasma with Alpha
    Therapeutics, Inc.

The Debtors are current with respect to their obligations under each of the 
contracts or leases specified above and are entitled to assume each such 
contract or lease.

    Paragraph 3 of Section 1123(b) specifies that a plan may provide for the 
settlement or adjustment of any claim or interest belonging to the debtor or 
to the estate and for the retention and enforcement by the debtor, by the 
trustee, or by a representative of the estate appointed for such purpose of 
any such claim or interest.  Section 7.5 of the Plan provides that all 
property of each of the bankruptcy estates, including but not limited to 
claims for relief under 11 U.S.C. Sections 544, 545, 546, 548, 549, 550 and 
551, shall be revested in the reorganized debtor of that estate.

    Paragraph 4 of Section 1123(b) specifies that a plan may provide for the 
sale of all or part of the property of the estate.  The provision is 
permissive, and the Plan does not provide for any sale of property.

    Paragraph 5 of Section 1123(b) specifies that a plan may include any 
other appropriate provision not inconsistent with the applicable provisions 
of the Code.  For example, Article III of the Plan specifies the treatment of 
unclassified claims.  This is entirely appropriate due to the confirmation 
requirements

                                      -12-

<PAGE>

specified in Section 1129(a)(9) of the Code.  Article I of the Plan contains 
the definitions of various terms of the Plan consistent with the purposes of 
the Code.  Miscellaneous provisions of the Plan provide for retention of 
jurisdiction by the Court, the discharge of the Debtors, and the issuance of 
stock.  Each of these provisions is consistent with the Code.

    Based upon the foregoing analysis, it is respectfully submitted that the 
Plan complies with the applicable provisions of Chapter 11, and, therefore, 
the requirements of Section 1129(a)(1) are met.
                
    B.   UNDER SECTION 1129(a)(2) THE PROPONENTS OF THE
         PLAN COMPLY WITH THE APPLICABLE PROVISIONS OF
         CHAPTER 11.

    The Debtors are the proponents of the Plan.  Chapter 11 essentially
requires the proponent to comply with Section 1125 before soliciting 
acceptances of the Plan and to comply with Section 1127 for any modification 
of a plan.

    Section 1125 of the Code specifies that acceptance or rejection of a plan 
may not be solicited after the commencement of a case unless at the time of 
or before such solicitation there is transmitted to the party being solicited 
a summary of the plan and a written disclosure statement approved by the 
court. Section 1125 also requires the same disclosure statement to be 
transmitted to each holder of the claim or interest of a particular class.  
As previously noted, the Debtors obtained entry of an order of this Court 
approving the Disclosure Statement.  The order specifies that the Disclosure 
Statement

                                      -13-

<PAGE>

contains adequate information.  SEE Exhibit "A" filed concurrently 
herewith.

    The attached Declarations of Jerry L. Burdick and Martin J. Brill show 
that the Debtors did not solicit the acceptance or rejection of the Plan from 
a holder of a claim or interest prior to the dissemination to such holder of 
a summary of the Plan and the written Disclosure Statement approved by the 
Court in the form of Exhibit "B" filed concurrently herewith.  As is shown by 
the Declaration of Martin J. Brill attached hereto, the Disclosure Statement 
was transmitted to each holder of a claim or interest of a particular class.

    Section 1127 of the Code provides that the proponent of the Plan may 
modify such Plan at any time before confirmation, but may not modify such 
Plan so that such Plan as modified fails to meet the requirements of sections 
1122 and 1123 of this Title. Contemporaneously with the Motion, the Debtor 
has filed a modification to the Plan, a copy of which is attached as Exhibit 
"D" hereto. The modification provides (1) that Barry D. Plost will become 
chairman, president and CEO of the Reorganized Debtors on the effective date 
of the Plan instead of Alfred Jay Moran, Jr. and (2) that the Reorganized 
Debtors shall amend their Articles of Incorporation to prohibit the issuance 
of nonvoting equity securities in compliance with section 1123(a)(6) of the 
Code.

    These amendments conform to and meet the requirements of sections 1122 
and 1123 of the Code.

    Furthermore, Federal Rule of Bankruptcy Procedure 3019 provides as follows:

                                      -14-
<PAGE>

      "In a chapter 9 or chapter 11 case, after a
      plan has been accepted and before its
      confirmation, the proponent may file a
      modification of the plan.  If the court finds
      after hearing on notice to the trustee, any
      committee appointed under the Code, and any
      other entity designated by the Court that the
      proposed modification does not adversely
      change the treatment of the claim of any
      creditor or the interest of any equity
      security holder who has not accepted in
      writing the modification, it shall be deemed
      accepted by all creditors and equity security
      holders who have previously accepted the
      plan."

    The modifications described above do not adversely change the rights of 
any creditor or interest holder.  By this Motion, the Debtor requests that 
the Court so find and that the Court order that the modification is deemed 
accepted by all creditors and equity security holders who have previously 
accepted the Plan.

    Based on the foregoing, it is respectfully submitted that the Debtors 
have complied with the applicable provisions of Chapter 11.  Therefore the 
requirements of Section 1129(a)(2) of the Code are met.
              
                                      -15-

<PAGE>

     C.   UNDER SECTION 1129(a)(3) THE PLAN HAS BEEN
          PROPOSED IN GOOD FAITH AND NOT BY ANY MEANS
          FORBIDDEN BY LAW.

    Bankruptcy Rule 3020(b)(2) provides that the Court need not require 
evidence that a plan has been proposed in good faith and not by any means 
forbidden by law if no objection has been filed.  The Debtors are not aware 
of any objections to the Plan on the basis that it was not proposed in good 
faith or was proposed by any means forbidden by law.  Therefore, this Court 
need not receive evidence on this issue.  The Debtors are prepared to offer 
testimony to show that the Plan has been proposed in good faith and not by 
any means forbidden by law to the extent it becomes an issue.
                 
     D.   UNDER SECTION 1129(a)(4) VARIOUS DISCLOSURES HAVE
          BEEN MADE.

    Section 1129(a)(4) of the Code requires that any payment made or promised 
by the proponent, debtor or person issuing securities or acquiring property 
under a plan for services or for costs and expenses in, or connection with, 
the case, or in connection with the plan, and incident to the case, has been 
disclosed to the Court and that any such payment, if made before 
confirmation, be reasonable or, if fixed after confirmation, be subject to 
the approval of the Court as reasonable.  Under the Plan, all professionals 
rendering services in the case are receiving compensation only with Court 
approval; all payments made or promised under the Plan have been disclosed to 
the Court in the Plan.

                                      -16-

<PAGE>

     E.   UNDER SECTION 1129(a)(5) DISCLOSURES REGARDING
          INSIDERS HAVE BEEN MADE.

    Section 1129(a)(5) of the Code requires the proponent of a Plan to 
disclose the identity of any individuals proposed to serve as officers, 
directors or voting trustees of the debtor after confirmation.  Such 
disclosures with respect to the Debtors have been made in Article IX of the 
Disclosure Statement. Concurrently with the filing of this Motion, the 
Debtors are filing an amendment to the Plan, which provides, in part, that on 
the Effective Date Barry D. Plost will replace Alfred Jay Moran, Jr. as 
Chairman, President and Chief Executive Officer.  The amendment, a copy of 
which is attached hereto as Exhibit "D", makes all the disclosures as 
required by Section 1129(a)(5).
                 
     F.   REGULATORY APPROVAL UNDER SECTION 1129(a)(6)

    Section 1129(a)(6) of the Code requires the approval of any regulatory 
commission of any rate change provided for in a plan.  The Plan provides for 
no rate change and, to the best knowledge of Debtors' management, no 
regulation commission has such jurisdiction.

                
     G.   UNDER SECTION 1129(a)(7) THE PLAN SATISFIES THE
          BEST INTERESTS OF CREDITORS TEST.

    Section 1129(a)(7) of the Code requires, with respect to each class of 
claims or interests, that the holder of a claim or interest in such class 
will receive or retain under a plan, on account of such claim or interest, 
property of a value, as of the affective date of the plan, that is not less 
than the holder

                                      -17-

<PAGE>

would receive or retain if the debtor were liquidated under Chapter 7 of the 
Code on such date.  This provision requires a liquidation analysis commonly 
referred to as the "best interest of creditors test."

    A liquidation analysis for each of the three debtor entities is presented 
in Article XII of the Disclosure Statement. In essence, it shows that 
unsecured creditors and shareholders would not recover any consideration for 
their claims or interests on liquidation.  Under the Plan, general unsecured 
creditors of ABI will receive a cash distribution up to a maximum of $.10 on 
the dollar, a PRO RATA distribution of common stock of reorganized ABI, plus 
50% of any net affirmative recovery received by the Debtors against the 
recipients of avoidable transfers.  Furthermore, general unsecured creditors 
of AVRE and Binary will receive cash in the amount of 80% of the allowed 
amount of their claims.  Thus, the Plan satisfies the requirements of Section 
1129(a)(7).

                
     H.   ALL CLASSES EXCEPT CLASS 2 HAVE ACCEPTED THE PLAN
          OR ARE NOT IMPAIRED UNDER THE PLAN UNDER SECTION
          1129(a)(8).

    Section 1129(a)(8) of the Code requires that each class of claims or 
interests is either unimpaired under the Plan or has accepted the Plan, 
subject to the so called "cramdown" provisions of Section 1129(b).  Pursuant 
to Section 1126 of the Code a class of claims has accepted a plan if at least 
two-thirds an amount and more than one-half in number of those voting have 
accepted the plan.  A class of interests has accepted a plan if at least 
two-thirds in

                                      -18- 

<PAGE>

amount of the allowed interests of those voting have accepted the plan.

    In this case, all classes and interests other than Class 2 are either 
unimpaired or have voted to accept the Plan. A tally of the balloting on the 
Plan has been filed contemporaneously with this Motion and a copy of the 
tally is attached hereto as Exhibit "E". The tally is summarized in the chart 
that follows:
                 
            I.   ACCEPTANCE BY CLASS 2 OF THE PLAN IS NOT NECESSARY
                (SECTION 1129(b)).
                 Section 1129(b) of the Code states, in pertinent part that:

    "(1) notwithstanding Section 510(a) of this Title, if all 
    of the applicable requirements of subsection (a) of this 
    Section other than paragraph (8) are met with respect to 
    a plan, the court, on request of the proponent of the plan,
    shall confirm the plan notwithstanding the requirements of 
    such paragraph if the plan does not discriminate unfairly, 
    and is fair and equitable, with respect to each class of 
    claims or interests that is impaired under, and has not 
    accepted, the plan.
            
    (2)  For the purpose of this subsections the condition that a plan be 
    fair and equitable

          with respect to a class includes the
          following requirements: (A) with respect to a
          class of secured claims, the plan provides --
          
              (i) (I) that the holders of such claims 
              retain the liens securing such claims,
              whether the property subject to such liens
              is retained by the debtor or transferred to
              another entity, to the extent of the allowed
              amount of such claims; and (II) that each 
              holder of a claim of such class receive on
              account of such claim deferred cash payments
              totalling at least the allowed amount of such 
              claim, of a value, as of the effective date 
              of the plan, of at least the value of such 
              holder's interest in the estate's interest 
              in such property; . . . "

    Thus, the acceptance of the Plan by the holder of the Class 2 Claim is 
not necessary if the Plan does not discriminate unfairly and provides that 
the holder of such claim retains its security interest and receives deferred 
cash payments totalling at least the allowed amount of the claim with a value 
as of the effective date of the holder's interest in its security.

    Unfair discrimination under Section 1129(b) only concerns the different 
treatment of unsecured claims of equal rank. SEE Pachulski, "The Cramdown and 
Valuation Under Chapter 11 of the Bankruptcy Code," 58 N.C.L. Rev. 925, 
936-938 (1980) ("...requirement that a plan not 'discriminate unfairly' seems 
to be designed to ensure that the defending class is not treated in an 
unfairly discriminatory manner vis-a-vis other classes of equal rank."); Klee, 
"All You Ever Wanted to Know About Cramdown Under the New Bankruptcy Code," 
53 Am. Bankr. L.J. 133, 141-142, 167-168 (1979) ("the legislative history 
states that the [prohibition against unfair discrimination] 'is included for 
clarity' and applies in the context of subordinated debentures. The 
requirement is intended . . . to permit the court to evaluate the complex 
relationship inherent in the relative priority of classes caused by partial 
subordination." (footnote omitted)); IN RE PINE LAKE VILLAGE APARTMENT CO., 
19 B.R. 819, 830 (Bankr. S.D.N.Y. 1982) (debtor cannot "cramdown" class 
consisting of the unsecured deficiency claim of an undersecured creditor 
while treating other unsecured claims differently,  "this [Section 1122(b) 
which allows a class of reduced claims for administrative convenience] is 
the only exception expressed in the Code for separately designating unsecured 
claims.  Any other designation would have to comply with 11 U.S.C. Section 
1129(b)(1) that prescribes as a prerequisite for confirmation that 'the plan 
does not discriminates unfairly.'"

    CVD's secured claim was properly treated in a separate class from all 
other claims because it is secured by different property than any other 
claims.  5 COLLIER ON BANKRUPTCY

                                      -21-

1122.03[6] at 1122-12 (15th ed. 1983) ("ordinarily each holder of an allowed 
claim secured by a security interest in specific property of the debtor must 
be placed in a separate class."); IN RE HOLLINGER, 15 B.R. 35 (Bankr. 
W.D.L.A. 1981) (Chapter 11 plan separately classifying creditors secured by 
different properties as property).  Thus, since there is no other secured 
claim of equal rank with respect to which Class 2 Claims are discriminated 
and, to the extent CVD may have any unsecured claim, that unsecured claim 
will be treated identically with all other unsecured claims in Class 3, the 
Plan does not unfairly discriminate against Class 2.

    It is also evident that the Plan satisfies the fair and equitable 
requirement by giving CVD a replacement note amortized over four years.  It 
has long been held that a stretching out of a secured creditor for a 
reasonable time with appropriate interest meets the fair and equitable 
requirement of S1129(b):
                
- -           . . . where dissenting claimant is receiving 
            payment in full over a reasonable period of time,
            with an appropriate interest or discount factor being
            paid, that creditor is receiving all that the law 
            requires, that is - full payment over a reasonable 
            period of time . . .  Therefore, payment over a 
            reasonable period of time with an appropriate interest
            or discount factor is generally the equivalent of 
            payment now; or at least, it is a satisfactory
            substitute (provided by
             
                                      -22-

<PAGE>


                reorganization law) for any rights
                surrendered by the secured claimant pursuant
                to the 'cram down' provided in the plan."

IN RE HOLLINGER, 15 B.R. 35 (Bankr. W.D.La. 1981).  The Ninth Circuit 
standard for determining a fair interest or discount rate has been set forth 
IN RE HOTEL ASSOCIATES, 165 B.R. 470 (9th BAP 1994) as follows:

         "To determine whether a secured creditor has been 
         provided the present value of its claim, the 
         bankruptcy court must make a case-by-case 
         determination of what interest the reorganizing 
         debtor would have to pay a creditor in order to obtain
         a loan on equivalent terms in the open market. 
         (citations omitted)  The appropriate interest rate 
         is the prevailing market rate for that type and
         quality of loan."
         
         In the instant case, the Debtors propose to pay down the current 
balance on the CVD obligation by $600,000 on the Effective Date and issue a 
replacement Note for the balance.  A copy of the proposed replacement Note is 
attached as Exhibit "C". The Note terms are fair and equitable as to CVD and 
provide, INTER ALIA, to fully amortize the balance over four years at an 
interest rate of 14% per annum.

         As the declaration of Steven Green, a partner of the business 
consulting firm of Kibel, Green Inc. shows, the 14% rate

                                      -23-

<PAGE>

proposed here actually exceeds the market rate for this type of loan and is 
more than fair and equitable -- even generous -- under the Ninth Circuit 
standard cited above.  Furthermore, CVD will retain all valid security 
interests it previously enjoyed. This includes all of the issued stock of 
AVRE and Binary.  This stock has been valued by the outside accounting firm 
of Duitch Franklin & Company at over $2,000,000.00.  SEE, Declaration of 
Chell Chelliah attached hereto. Accordingly, the CVD obligation, which will 
be paid down to approximately $1 million on the Effective Date will be 
secured by assets worth at least $2 million.  Furthermore, business 
projections of the Debtors, which Duitch Franklin & Company have examined and 
find reasonable, show the Reorganized Debtor will be able to meet its 
obligations under the Plan, including repayment of the replacement Note to 
CVD.

         Thus, since the Plan does not discriminate unfairly and is fair and 
equitable with respect to Class 2, the acceptance of the Plan by Class 2 is 
not necessary for the Plan to be confirmed.
         
     J.   UNDER SECTION 1129(a)(9) PRIORITY PAYMENTS ARE
          TREATED APPROPRIATELY UNDER THE PLAN.

         Section 1129(a)(9) of the Code requires particular treatment with 
respect to priority claims.  Under subparagraph (A), administrative claims and 
expenses entitled to priority under Section 507(a)(1) are entitled to cash on 
the effective date of the Plan equal to the allowed amount of the claim 
unless the holder of the claim agrees to a different treatment.  Section 3.1 
of the Plan so provides.

                                      -24-

<PAGE>

         Under subparagraph (B), a class of claims of the kind specified in 
Section 507(a)(3), (4), (5), (6) or (7) is entitled to receive cash on the 
effective date of the Plan equal to the allowed amount of such claim unless 
the class has voted to accept deferred payment.  Under Section 4.1 of the 
Plan, Class 1 (consisting of unsecured claims entitled to priority under 
507(a)(3), (4), (5), (6) or (7) of the Bankruptcy Code) is entitled to 
receive cash on the effective date of the Plan, unless such holder shall have 
agreed to a different treatment. Thus, the Plan complies with Section 
1129(a)(9)(B).

         Under subparagraph (C), each holder of a priority tax claim as 
specified in 507(a)(8) is entitled to receive deferred cash payments over a 
period not exceeding six years after the date of assessment of such claim of a 
value, as of the effective date of the Plan, equal to the allowed amount of 
such claim. Under Section 3.2 of the Plan, tax claims against the Debtors shall
be paid in full in cash on the effective date or as soon thereafter as is 
practicable.  Accordingly, since the Plan provides more favorable treatment 
than required by the Code, the Plan complies with Section 1129(a)(9)(C).
         
     K.   UNDER SECTION 1129(a)(10) AT LEAST ONE CLASS OF
          IMPAIRED CLAIMS HAS ACCEPTED THE CCI PLAN.

         Section 1129(a)(10) of the Coda requires that if a class of claims is 
impaired under the Plan, at least one class of claims that is impaired under 
the Plan has accepted the Plan, determined without including any acceptance 
of the Plan by any insider.  In this case, Classes 3, 4, 5, 6, and 7, all 
impaired

                                      -25-

<PAGE>

classes, have voted to accept the Plan as discussed in Section H of this 
memorandum.  Also SEE Exhibit "E."  Thus the requirements of 1129(a)(10) are 
satisfied.

     L.   UNDER SECTION 1129(a)(11) THE PLAN IS FEASIBLE.

    Section 1129(a)(11) requires that the Court find that confirmation of the 
Plan is not likely to be followed by the liquidation or the need for further 
financial reorganization of the Debtor.  In this connection, the Debtors have 
provided financial projections for the life of the Plan.  Those projections 
show that the Debtors will be able to meet all of their post-confirmation 
obligations without the further need of financial reorganization.  These 
projections together with supporting records have been analyzed by the 
outside accounting firm of Duitch Franklin & Company and found to be 
reasonable. SEE Declaration of Chell Chelliah attached hereto.

    Furthermore, the Debtors have obtained the necessary funding to meet its 
obligations under the Plan following confirmation.  SEE Declaration of Jerry 
Burdick attached hereto. Accordingly, the Debtors will be able to make all 
payments required under the Plan and the Reorganized Debtors will be able to 
operate following confirmation of the Plan without liquidation or the need 
for further financial reorganization.
         
     M.   UNDER SECTION 1129(a)(12), ALL FEES PAYABLE UNDER
          SECTION 1930 OF TITLE 28 HAVE BEEN PAID.

    Section 1129(a)(12) requires that the Court find all fees payable under 
Section 1930 of Title 28, as determined by the

                                      -26-

<PAGE>

Court at the hearing on confirmation of the Plan, have been paid or the Plan 
provides for the payment of all such fees as of the effective date of the 
Plan. As is shown by the Declaration of Jerry Burdick, all such fees have 
been paid or will be paid prior to the hearing on confirmation of the Plan.  
Accordingly, the requirements of 11 U.S.C. Section 1129(a)(12) have been mat.

     N.   THE REQUIREMENTS OF SECTION 1129(a)(13) HAVE BEEN
          MET.

    Section 1129(a)(13) requires that the Plan provide for the continuation 
after its effective date of payment of all retiree benefits established prior 
to confirmation of the Plan for the duration of the period the Debtor is 
obligated itself to provide such benefits.  In this case, none of the Debtors 
have provided retiree benefits at any time prior to confirmation. 
Accordingly, the Debtors are not required to make provisions in the Plan 
under this section and have therefore met the requirements of Section 
1129(a)(13).

    Based on the foregoing discussion, the Debtors respectfully request that 
the Plan be confirmed by this Court.

                             DECLARATION OF MARTIN J. BRILL
                             ------------------------------

    I, MARTIN J. BRILL, do hereby declare as follows:

    1.   I am an attorney at law duly licensed to practice before this Court. 
I am a member of Robinson, Diamant, Brill & Klausner, attorneys for the 
Debtors herein.  I have personal knowledge of the facts stated herein and if 
called as a witness, could and would testify competently thereto.

    2.   These proceedings were commenced January 7, 1994 by the filing of 
voluntary petitions by each of the Debtors under chapter 11 of the Bankruptcy 
Code.  Early in the case the Court entered an order approving joint 
administration of all these cases thereby avoiding duplication of costs and 
expenses.

    3.   By order entered September 21, 1994 the Bankruptcy Court authorized 
ABI to obtain up to $4.5 million in credit through the issuance of Debtors' 
Notes.  The Debtors filed a plan based on such financing.  ABI initially 
attempted to place the Notes through Relco Corporation ("Relco"), an 
investment banking firm primarily engaged in restructuring and financing 
companies in chapter 11.  Relco was unable to place the Notes, and ABI was 
forced to turn to other sources and withdraw the Plan based on financing from 
Relco.

    4.   More recently, ABI received a best efforts commitment from First 
Equity Capital Corporation ("First Equity") to place $1.2 million in Debtors' 
Notes with its clients, which will net approximately $1 million to ABI.  
Based on this new financing source, the Debtors filed their Second Amended 
Joint Plan on October 26, 1995.  In order to meet certain objections to
                                           

                                      -29-

<PAGE>

the Second Amended Joint Plan and its accompanying disclosure statement, the 
Debtors filed their Third Amended Joint Plan of Reorganization (the "Plan") 
and accompanying disclosure statement.  The disclosure statement for the Plan 
was approved by the Court on by order entered December 28, 1995 pursuant to a 
hearing held December 6, 1995 as containing adequate information and was 
disseminated to creditors and other interested parties together with the 
ballots and certain other materials on December 8, 1995.  A copy of the order 
approving the disclosure statement for the Plan is attached hereto as Exhibit 
"A".

    5.   As of the date of the filing of this Motion, the $1.2 million in 
Debtors' Notes have been substantially subscribed.  As is shown more fully in
the disclosure statement to the Plan, full subscription of $1.2 million in 
Debtors' Notes will yield sufficient cash to fund the Plan.

    6.   Meanwhile, CVD Financial Corporation ("CVD") obtained relief from 
stay to foreclose on its security effective January 2, 1996 by order entered 
August 25, 1995.  CVD is the major creditor of the Debtors and is secured by 
the assets of each of the Debtors and the stock of AVRE and Binary.  On 
November 29, 1995 the Debtors filed a complaint against CVD seeking to enjoin 
CVD from proceeding with foreclosure until after the confirmation hearing on 
the Plan.  Hearing on a preliminary injunction in connection with the company 
scheduled for December 20, 1995 has been continued to January 17, 1996, and 
CVD has agreed that it will not foreclose on its security until after the 
hearing on January 17, 1996.

    7.   After obtaining approval of the Disclosure Statement, on behalf of 
the Debtors, I caused materials consisting of the Disclosure Statement, the 
form of Ballots, the Notice of Hearing to Consider Confirmation of the Plan 
and time for fixed for filing acceptances or rejections of Plan, and a letter 
from counsel to the Official Creditors Committee to be mailed to creditors 
and interested parties.  A true and correct copy of the materials so mailed 
is attached hereto as Exhibit                                          "B".

    8.   These materials were mailed on December 8, 1995 under my direction 
to all entities for whom Proofs of Claim or interest have been filed under 
the Chapter 11 cases, to the holders of allowed claims, to holders of record 
of the Debtors securities, the U.S. Trustee, and to all persona requesting 
special notice in the cases.

    9.   To my knowledge, none of the Debtors solicited votes accepting or 
rejecting the Plan prior to December 8, 1995.

    10.  The Plan proposes to pay down the CVD obligation by $600,000 on the 
effective date and give CVD a Replacement Note for the balance amortized over 
4 years.  A true and correct copy of the proposed Replacement Note la 
attached hereto as Exhibit "C" and is incorporated herein by this reference.

    11.  I am the person responsible for tabulation of the votes accepting or 
rejecting the Plan.  True and correct copies of the tabulations of the votes 
accepting or rejecting the Plan, which votes were received prior to 5:00 
p.m., December 29, 1995, are attached hereto as Exhibit "E" and incorporated 
herein by

                                      -31-

this reference.  To the beat of my knowledge, the tabulations filed as 
Exhibit "E" are accurate and complete.

    12.  Attached hereto as Exhibit 'D' is a true and correct copy of the 
Amendment to the Plan filed by the Debtors, the Plan proponents herein.

    I declare under penalty of perjury that the foregoing is true and correct 
and that this Declaration was executed on January 2, 1996, at Los Angeles, 
California.

                        DECLARATION OF JERRY L. BURDICK
                        -------------------------------

    I, JERRY L. BURDICK, do hereby declare as follows:

    1.   I am the Executive Vice-President, Finance and Administration, and 
Chief Financial Officer of each of the Debtor entities.  I have personal 
knowledge of each of the facts set forth herein and if called as a witness, 
could and would testify competently thereto.

   2.   Pursuant to Article IX of the Plan, the Debtor seeks to assume the    
 executory contracts and unexpired leases:

         (1)  Leases of real property for the following locations:

               (a)  611 N. Law Vegas Boulevard, Las Vegas,
                    Nevada;

               (b)  1174 Port Campbell Boulevard, Clarksville,
                    Tennessee;
    
               (c)  129 and 141 N. Spruce, Colorado Springe,
                    Colorado; and
    
               (d)  411 and 413 West 4th Street, Pueblo,
                    Colorado.
         (2)  Contracts for sale of source plasma with Alpha Therapeutics, Inc.

    3.   The Debtors are current with respect to their obligations under each 
of the executory contracts or unexpired leases specified above, and are 
entitled to assume such contracts or leases.

                                      -33-

<PAGE>

    4.   To my knowledge, neither the Debtors herein nor anyone acting on 
their behalf solicited votes accepting or rejecting the Plan prior to 
December 8, 1995.

    5.   I am informed and believe that the funding to be provided by First 
Equity Capital Corporation is substantially in place and will be fully 
subscribed in advance of the date set for hearing on the Disclosure Statement.

    6.   Each of the Debtors is current with respect to fees payable under 
Section 1930 of Title 28 and will make such further payments as determined 
by the Court at the hearing on the confirmation of the Plan.

    7.   I have personally prepared the insolvency analysis contained in the 
Disclosure Statement for the Third Amended Joint Plan of Reorganization of 
American Blood Institute, Inc.; AVRE, Inc., and Binary Associates, Inc.  The 
statements contained therein are based on records of the Debtors and 
accurately reflect those records.  The liquidation analysis shows, and it is 
my opinion that in the event of a Chapter 7 liquidation there would be no 
funds to distribute to general unsecured creditors in any of the bankruptcy 
estates herein.

    I declare under penalty of perjury under the laws of the United States of 
America that the foregoing is true and correct and that this Declaration was 
executed at Los Angeles, California on January 2, 1996.

                            DECLARATION OF STEVEN GREEN
                            ---------------------------

     I, Steven Green, do hereby declare as follows:

    l.   I am 42 years of age, a recognized specialist in turnaround crisis 
consulting management, and the Co-Pounder and President of the Los 
Angeles-based management consulting firm of Kibel, Green Inc.  I am known for 
taking troubled companies and turning their crisis condition into one of 
healthy stability. I have had extensive experience assisting debtor companies 
restructure and refinance in Chapter 11 bankruptcy proceedings.

    2.   Founded in 1984, Kibel, Green Inc. advises a wide range of companies 
in a diversified array of industries such as real estate, manufacturing, 
aerospace, service, distribution, retail and financial institutions.  The 
firm has been involved with more than $5 billion of refinancing and has 
advised hundreds of companies.

    3.   Prior to starting Kibel, Green Inc., I directed the turnaround of 
several failing companies.  Working concurrently as Chief Operating Officer 
for four separate companies, one operating under the protection of Chapter 11 
bankruptcy proceedings, while the other three experienced varying degrees of 
financial and operational difficulties, I was able to reorganize and 
stabilize each company.  These successful turnarounds earned me a reputation 
for creativity, tenacity, and financial acumen, and led me to co-found the 
now nationally recognized advisory firm of Kibel, Green Inc.

    4.   I am one of a handful of individuals across the nation who has both 
an undergraduate and graduate degree in

                                      -35-

<PAGE>

entrepreneurship.  My undergraduate degree is from Northeastern University, 
Boston (1976), and my graduate degree is from the University of Southern, 
California (1977).  I have taught classes at Cal Poly and given seminars of 
"Managing Your Company During Crisis Situations."  In addition, I am a 
sought-after lecturer and have written published articles covering topics 
associated with financially troubled companies.

    5.   Also active in other educational pursuits, I am a member of the 
Advisory Council for the Entrepreneur Program at the University of Southern 
California.  The Advisory Council is comprised of successful business men and 
women who donate their time and money to students in the Entrepreneur 
Program. Recently I was honored as the "Outstanding Alumni of the Year" award 
by the University of Southern California Entrepreneur Program.  I am also a 
member of the Los Angeles Chapter of Young Presidents Organization.

    6.   I am familiar with the obligation owed to CVD Financial Corporation 
("CVD") by American Blood Institute, Inc. ("ABI"), AVRE, Inc. ("AVRE") and 
Binary Associates, Inc. ("Binary').  I am also familiar with the provisions 
made by payment of the CVD obligation in the Third Plan of Reorganization of 
ABI, AVRE, and Binary.  In that regard, I am familiar with the terms of the 
Replacement Note to be given CVD under the Plan.

    7.   Current market interest rates for secured loans to reorganized 
Debtors is in the range of Prime plus 4% to Prime plus 7%, which in today's 
market would be 12 1/2% to 15 1/2%.

                                   -36-

<PAGE>

    8.   It is my opinion that the proposed rate of 14% interest on the CVD 
Replacement Note is in the range of current market interest rates for loans 
of this nature.

    I declare under penalty of perjury under the laws of the United States of 
 America that the foregoing is true and correct and that this Declaration was 
executed at Los Angeles, California on January 3, 1996.

                         DECLARATION OF S. CHELL CHELLIAH
                         -------------------------------


I, S. CHELL CHELLIAH, declare as follows:

    1.   I submit this declaration in support of the THIRD AMENDED JOINT PLAN 
OF REORGANIZATION ("PROPOSED PLAN") of American Blood Institute, Inc. 
("ABI"); AVRE, Inc. ("AVRE") and Binary Associates, Inc. ("Binary"), Debtors 
in Possession herein (collectively "the Debtors") and to address the 
objections of CVD Financial Corporation ("CVD") relating to the financial 
viability of the PROPOSED PLAN. I am a member of Duitch, Franklin & Co., 
("DF&Co.") Certified Public Accountants and Business Consultants, which has 
been retained by the Debtors as financial consultants subject to 
authorization by the United States Bankruptcy Court. The facts stated herein 
are based on my own personal knowledge, except those on information and 
belief, and as to those facts, I am informed and believe that they are true.

    2.   I am a Certified Public Accountant, a Certified Fraud Examiner, a 
Certified Insolvency and Reorganization Accountant and the head of the 
Litigation Support and Insolvency Services Group of DF&Co. I have spent the 
last fourteen years in public accounting as an investigative accountant, 
financial consultant and auditor with an international firm as well as with 
DF&Co. During this time I have performed numerous audits, business 
valuations, due-diligence reviews including financial viability studies and 
collateral reviews for buyers of businesses and finance corporations, 
directed Chapter 7 liquidations, Chapter 11 plans of reorganization and state 
court receiverships, including litigation support services as accountant to 
the trustee, examiner, creditors' committee, debtor in possession and 
receiver. Further details regarding my background and qualifications can be 
found in my resume, a true and correct copy of which is attached as Exhibit 7 
and is incorporated herein by this reference.

    3. This declaration sets forth my opinions as an independent accountant 
concerning the reasonableness of the underlying assumptions of the Debtors 
financial projections and the related impact on the overall financial 
viability of the PROPOSED PLAN. Based on the Debtors financial projections, I 
have also opined on the estimated collective value of the stock of AVRE and 
Binary. Furthermore, I have investigated the issues and objections raised by 
CVD pertaining to certain financial aspects of the PROPOSED PLAN. The outcome 
of these investigations and my opinion on the validity of these issues

                                      -l-

<PAGE>

and concerns are also set forth in this declaration. In forming these 
opinions, I have relied only on the types of information upon which I and 
other persons within my area of expertise customarily and necessarily rely 
upon.

    4. Specifically, I have relied primarily upon my personal inspection of 
the past financial history, disclosure statement, PROPOSED PLAN, the Debtors 
financial projections, articles and statistics published by the American 
Blood Resources Association ("ABRA") on the plasma and plasma products 
industry, discussions with Mr. Alfred J. Moran, Jr., Mr. Jerry L. Burdick and 
Mr. Brian Olsen, the key personnel of the Debtors ("Management").

OVERVIEW

    5. Based on my personal inspection and investigation of the Debtors 
financial history, future   outlook and the plasma industry, it is my opinion 
that the underlying assumptions of the Debtors   projections, as reflected in 
the disclosure statement (see Exhibit 6) and PROPOSED PLAN, are   reasonable. 
Based on this, it is my opinion that the PROPOSED PLAN is viable with respect 
to these   aspects. The estimated total collective value of the stock of AVRE 
and Binary, based on the Debtors   financial projections, is in my opinion, 
in excess of $2,000,000. The issues and objections raised by  CVD, relating 
to the financial viability of the PROPOSED PLAN, were investigated (addressed 
in detail   below) and were found to be without merit. The financial 
projections were prepared by Management   of the Debtors and are based upon 
assumptions which I believe are reasonable. Nevertheless, no   assurance can 
be given that any of the results or events described in the PROPOSED PLAN and 
the   Debtors financial projections will occur in the manner stated and at 
the predicted times. Actual results   may vary from projected results.    

BACKGROUND

    6. ABI was incorporated in 1986 and was initially engaged in the business 
of whole blood collection and distribution on a "for profit" basis, which 
proved to be unprofitable. The current  Management team was brought in 1993, 
to perform an in-depth analysis of the business and to formulate  and 
implement corrective measures. After completing the analysis, the Management 
decided to change the focus of the business from whole blood to the more 
profitable plasma collection business.

                                       -2-

<PAGE>

Accordingly, ABI obtained financing and acquired the six plasma collection 
centers (AVRE and Binary) which now form the core business of the Debtors. 
The Debtors product is source plasma. Source plasma is plasma collected from 
humans. Plasma is the liquid part of blood and is collected with a procedure 
similar to giving blood. The clear plasma is mechanically separated from the 
cellular elements of the blood (such as red and white blood cells and 
platelet) through centrifugation and/or membrane filtration at the time of 
the donation. These cellular elements are then returned to the donor as part 
of the same procedure. The process of collecting plasma is known as 
plasmapheresis. Because blood cells are returned, it is possible for 
individuals to donate plasma more frequently than whole blood. Donations of 
plasma can be made up to twice a week or 104 times per year by an individual 
pursuant to FDA rules (medically, a donor can give 182 times a year). Most 
regular donors give between 40 to 60 times per year. The six plasma centers 
of the wholly owned subsidiaries (AVRE and Binary) of ABI are currently 
operating under the d.b.a. SeraCare. The name SeraCare is registered with the 
United States Patent and Trademark Office. Management anticipates that after 
emergence from Chapter 11, ABI will file for a name change from ABI to 
SeraCare, Inc. The locations of the six plasma collection centers are:

              a)   Las Vegas, Nevada
              b)   Phoenix, Arizona
              c)   Colorado Springs, Colorado (two centers)
              d)   Pueblo, Colorado
              e)   Clarksville, Tennessee


The Debtors filed for protection under Chapter 11 of the Federal Bankruptcy 
Code on January 7, 1994 when the secured lender (CVD) called a default and 
attempted to foreclose on the six plasma collection  centers.   

    7. Based on the foregoing, the factors that should be taken into 
consideration in reviewing the financial history of the Debtors are:          

               (a) ABI's business changed dramatically in late 1993 and 1994 
                   from whole blood to plasma
                            
                                      -3-

<PAGE>

      (b)  The change was achieved through acquisition of six plasma 
           collection centers via two wholly owned subsidiaries, AVRE, Inc. 
           and Binary Associates, Inc.
      (c)  During 1994 and early 1995 Management has essentially completed the
           internal restructuring of the plasma operations which included; 
           structural and cosmetic upgrades to the centers; personnel changes 
           and improved marketing efforts.
      (d)  Internal restructuring would have impacted the immediate revenue and
           profitability of the business whilst in transition.
      (e)  The later period in 1995 would therefore, be more indicative of the
           future potential and profitability of the Debtors.

PLASMA INDUSTRY OVERVIEW

    8.  The source plasma is sold to fractionators who process the plasma 
into two primary groups of plasma products; injectible and non-injectible.  
The fractionators process the collected plasma through two sterilization 
processes which are specifically designed to kill bacterial or viral 
occurrences. Because of the commingling of plasma from various suppliers and 
the sterilization process, the fractionators bear substantially all risks of 
plasma received by end users.

    9.  Specialty plasmas generally contain high concentrations of specific 
antibodies and are used primarily to manufacture immune globulin therapeutic 
products, which bolster the immunity of patients or treat certain immune 
system disorders.  The Debtors currently collect and sell two specialty 
plasmas, Cytomegalovirus Antibody Plasma ("CMV") and Tetanus antibody plasma. 
The Debtors intends to place a greater emphasis on the collection of 
specialty plasmas by identifying potential specialty plasma donors through 
screening and testing procedures, and by developing more FDA-licensed 
programs to inoculate donors.

    10.  Depending on the rarity of the antibody or medical history of the 
donor, the pricing for specialty plasmas currently range from $80 to $3,500 
per liter.  The average spot price of source plasma is currently 
approximately $76.  Donors are typically paid from $15 to $25 per visit.  The 
source plasma industry has experienced a number of fluctuations in the supply 
and demand cycles.  The market factors driving the plasma industry include:

                                     -4-

<PAGE>

        a)   The expanded use of immune globulins to prevent and treat
             disease.
        b)   The worldwide plasma shortage.
        c)   Extensive public concern over the safety of blood products.
        d)   An increase in regulatory control over the collection and testing
             of plasma.

A worldwide shortage of plasma began in 1991, driven partly by the increased 
need for plasma components to treat larger and older populations, and partly 
by a diminished pool of donors that resulted from more restrictive testing 
and screening requirements imposed by regulatory authorities.  In 1991 the 
FDA required mandatory screening for Hepatitis C, thereby disqualifying 
donations from a significant portion of the then existing donor base.  
Another market factor has been the increasing concern over HIV and other 
viruses, which has led to increased testing and higher scrutiny.

    11. The source plasma is sold to fractionators.  The five leading 
fractionators in the U.S. are:

        a)   Alpha Therapeutic Corporation
        b)   Armour Pharmaceutical
        c)   Miles Laboratories
        d)   Hyland Therapeutics
        e)   North American Biologicals, Inc.

The Debtors generally sell their plasma (approximately 32% currently) under 
contracts ranging from one to three years which allow for annual pricing 
renegotiations.  Pricing for product deliveries is generally mutually agreed 
to prior to the beginning of the contract year and fixed for that year. 
Consequently, the Debtors may be adversely or beneficially affected if, 
costs of producing and selling plasma rise or fall during the year, as a 
result of changes in governmental regulation, changes in donor fees or other 
factors.  In fact the Debtors operations were adversely impacted in April 
1995 due to a surprise curtailment in volume by their main contractual 
customer (see section on Current Operations).

    12. The total number of plasma centers in the U.S. was estimated at 440 
as of February 1994. Total collections of plasma in the U.S. for the 
comparable period approximated 8,100,000 liters which approximates to 
18,400 liters per center per year.  The industry is fairly evenly distributed 
with large numbers of small operators and three larger operators with greater 
than 30 centers (see below) .  These

                                     -5-

<PAGE>

organizations would form the main competitors to the Debtors operations.  
Note that the larger competitors are also the main contractual customers of 
the Debtors:

      Total number of centers in the U.S.    100%                  440
      --------------------------------------------------------------------

    13.  Donors vary depending upon the location of the centers as well as 
the donor's economic status.  Donors are typically paid from $15 to $25 per 
visit.  They commonly include blue collar workers, housewives, college 
students and military personnel.  Ages range from 18 to 60, with the  
predominant number being white males under 30 and middle-aged housewives. 
Typically 20% are females, 22% are college students, 77% are Caucasians and 
85% are below 40 years of age.  Medically, a donor could give 182 times a 
year; however, FDA standards restrict the frequency to twice a week or 104 
times per year.  Most regular donors give between 40 to 60 times per year. 
Quality Plasma Program certification now excludes drug or alcoholic addicts 
or homeless persons by requiring proof of permanent address as well as 
alcohol and drug use testing.

    14.  The Debtors has qualified all six centers for Quality Plasma Program 
("QPP") certification by the American Blood Resources Association.  Within the 
past five years, ABRA has created this certification process which has been 
successful in upgrading the U.S. plasma collection industry.  Examples of the 
strict rules which are enforced by the FDA, state authorities and ABRA

                                     -6-

<PAGE>

include facilities upgrade, high operating standards, strict donor screening 
for drugs and disease, verified addressess for all donors, use of a national 
registry of deferred donors and viral reactive rate within prescribed limits.

CURRENT OPERATIONS

    15.  The Debtors six plasma collection centers currently collect 
approximately 9,500 liters of plasma per month (114,000 liters per annum or 
19,000 liters per center per annum).  Approximately thirty two percent (32%) 
of this plasma is sold under a long term contract to Alpha Therapeutics 
Corporation, a subsidiary of Green Cross Corporation of Japan.  Alpha 
Therapeutics is one of the major companies in the plasma collection, 
fractionation and product distribution businesses in the U.S.  Approximately 
forty two percent (42%) of the Debtors plasma is sold through brokers to 
European fractionators.  Approximately twenty six percent (26%) of the 
Debtors collected plasma is sold as specialty plasma (Hyperimmune 
plasma-Tetanus and CMV) to domestic customers.

    16.  The actual operating results for the ten month period to October 31,
1995 were as follow (See Exhibit 1 and 2):

                                     -7-

<PAGE>

    17.  The actual results of the Debtors for the 10 month period to October 
31, 1995 (for the existing six centers), show that the months April, May, 
June, and July were abnormally low compared to the months January, February, 
March, August, September and October of 1995 (See Exhibit 1).  This reduction 
reflects the fact that Alpha Therapeutics, for the first time in ten years 
exercised its contractual option to decrease its purchase of source plasma 
volumes by twenty five percent (25%) for six months.  The Debtors Management 
used this opportunity to negotiate a CMV Hyperimmune program and a Tetanus 
hyperimmune stimulation program with North American Biologicals, 
Incorporated; thus, more than compensating for the twenty five percent (25%) 
shortfall in volume, at a $2.00 per liter increase in margin for Tetanus and 
an $8.00 per liter increase in margin for CMV hyperimmune plasma.  The time 
it took to initiate the hyperimmune programs negatively impacted earnings; 
however, as can be seen, beginning with September 1995, the earnings 
recovered to near first quarter actual for 1995.  Furthermore, the new 
contract with Alpha Therapeutics, beginning January 1996, includes a lower 
maximum reduction possible of ten percent (10%) instead of the previous 
twenty five percent (25%).

OVERVIEW OF FINANCIAL OUTLOOK AND PROJECTIONS

    18.  The Management believes that the Debtors are ready to emerge from 
Chapter 11 and that it can improve the profitability of the present centers 
by expanding marketing efforts, focussing more on specialty plasmas, and 
continuing to reduce costs.  In addition, the Debtors plan to grow over the 
next four years through the acquisition of additional plasma collection 
centers and the development of higher profit hyperimmune plasma stimulation 
programs in addition to its current Tetanus and CMV programs.  Currently, 
most of the specialty plasma is derived serendipitiously (not the result of 
stimulation).

    19.  The fundamental elements of the Debtors business strategy are:

         a)   To manage the existing centers effectively to increase operating
              efficiency, monthly volume and profitability. 

         b)   To maintain all facilities at QPP standards (the industry quality
              standards for plasma collection centers).

         c)   To pay close attention to trends in the plasma market in order to
              maintain an optimal mix of contract and spot market sales.

                                     -8-

<PAGE>

         d)   To initiate an aggressive program to acquire additional plasma
              centers, utilizing internally generated cash flow.  The Debtors
              believes that it will be possible to increase its centers from 
              the current six (6) to twelve (12) over a four year period from 
              internally generated cash flows.  This does not take into account 
              the additional significant impact possible from acquiring 
              additional centers by raising external financing.

         e)   To institute a specialty plasma collection program whereby 
              specialty plasma donors within the Debtors donor base are 
              identified and their plasma is collected and sold at higher 
              margins.

         f)   To develop a hyper-immune specialty plasma business by converting

ASSUMPTIONS UNDERLYING FOUR YEAR FORECAST

    20.  The detailed assumptions prepared by the Debtors which supports the 
Debtors financial projections is attached as Exhibit 6 and was extracted 
from Exhibit C of the disclosure statement of the PROPOSED PLAN.  A review of 
the charts above and supporting Exhibits 1, 2 and 3 show that the revenue 
projections for Year 1 are approximately 11% below the annualized current 
year (1995) results with net operating profits almost on-par with the 
annualized 1995 results.  The increased margins are

                                     -9-

likely to be achieved given that Management already has a more profitable 
contract with North American Biologicals, Incorporated.  As mentioned 
before, during 1995, Management negotiated a CMV hyperimmune program and a 
Tetanus hyperimmune stimulation program with North American Biologicals, 
Incorporated, at a $2.00 per liter increase in margin for Tetanus and an 
$8.00 per liter increase in margin for CMV hyperimmune plasma.  Based on all 
of the foregoing, I believe that the Debtors financial projections for Year 1 
are reasonable.

    21.  The Debtors financial projections for Year 2 to 4 are all based on 
similar gross profit margins as Year 1, but take into account increased 
revenues and profits from newly acquired centers.  The increase in indirect 
(administrative and overhead type) expenses are reasonably expected to be 
less than directly proportional.  In other words as the Debtors continue to 
expand through acquisition of new centers, economies of scale would help 
beneficially impact the net operating profits.



                                   [CHART]



Overall the Debtors revenue projections and gross profit margins per center 
are reasonable based on the actual results to date.  Furthermore, the Debtors 
projected gross profit margins show a progressive decrease with the 
increasing number of centers.  This is reasonable and allows for any 
inefficiencies that may arise as a result of the expansion.  Eventually it 
can be contemplated that the higher profit margins will be achieved by the 
Debtors as the business stabilizes after a period of rapid growth.

The average monthly net operating profit per the Debtors actual and 
projections are as follows:

            September                $29,608             6          $4,935

            Projection - Year 2      $28,096             6.42       $4,376

            Projection - Year 3      $37,557             7.67       $4,897

            Projection - Year 4      $54,688            10.75       $5,087

Based on all of the foregoing, I believe that the assumptions underlying the 
Debtors four year financial projections are reasonable.

ISSUES AND CONCERNS RAISED BY CVD

    22.  Pertinent excerpts from CVD Financial Corporation's objections to 
the disclosure statement for the PROPOSED PLAN ("the CVD objections") read as 
follows:

         a)   Page 3, lines 11 and 17; "The Debtors actual post-petition 
              financial results severely question the plan's feasibility and 
              the Debtors projections.  The Debtors

                                     -11-
<PAGE>
              so-called profitable operations appear to be no more than creative
              accounting by delaying and doubling the unpaid accounts payable.  
              The Debtors projections forecast more than double the average 
              monthly net income per plasma center received in the 12 months 
              operating results."

         b)   Page 5, lines 1 to 3; "The operating reports of Binary show
              that the outstanding accounts payable as of August 31, 1995, have 
              doubles since March 1995 while gross sales have declined."

         c)   Page 5, lines 6 to 8; "The substantial unpaid accounts payable 
              raise questions about the purported "profitability" of Debtors 
              operations 1995."

         d)   Page 5, lines 20 to 22; "However, in the three months 
              ending August 31, 1995, AVRE and Binary had a combined net income,
              before bankruptcy expenses, of approximately $42,000."

RESPONSE TO ISSUES AND CONCERNS RAISED BY CVD

    23.  The main issue raised in (a), (c) and (d) relates to the past 
profitability of the operations as an indicator of the future profitability as
reflected in the Debtors financial projections.  In expressing concern 
regarding the profitability of the Debtors, CVD fails to take into 
consideration the following facts:

         a)   The Debtors operations have undergone a significant 
              reorganization and are now returning to a more stable mode of 
              operations.

         b)   The Debtors operations during the months of April, May, June and
              July were adversely affected by the surprise volume reduction 
              action taken by their main contractual customer (see section on 
              Current Operations).

         c)   Management had taken  corrective action to compensate for this
              unforeseen and unusual event (see section on Current Operations).

         d)   Based on all of the foregoing and on the profitable results of
              the earlier months.  The later months in 1995 should accepted as 
              more indicative of the future potential and profitability of the
              Debtors.

                                     -12-

<PAGE>

    24.  The actual operating results of August, September and October of 
1995 were significantly profitable and show a marked improvement compared to 
the prior months (see section on "Current Operations").  The Debtors net 
operating profit for the later months in 1995 were as follows:

              August                         $20,440

              September                      $29,608

              October                        $37,219
                                             -------
              Total for three months         $87,267
                                             -------
              MONTHLY AVERAGE                $29,089
                                             -------

The Debtors were also significantly more profitable in the earlier months of 
1995 as follows:

              January                        $35,712

              February                       $34,248

              March                          $34,672
                                             -------
              Total for three months        $104,632
                                             -------
              MONTHLY AVERAGE                $34,877
                                             -------

Therefore, it is clear that net operating profits in excess of $25,000 per 
month with six operating centers is reasonable for the Debtors and that this 
amount can reasonably be expected to increase with additional centers.

    25.  The financial projections for the first twelve months after 
reorganization ("Year 1") are based on average monthly net operating profits 
of $21,220 (based on six operating locations) and are thus comparable and 
consistent with the actual results proven to be achievable in 1995.  In my 
opinion, the amounts reflected in the first twelve month projections by the 
Debtors, are reasonable for the reasons specified above.  The latter twelve 
month periods show progressive increase in net operating profits with a 
progressive increase in the number of operating locations.  The rationale for 
this is that indirect expenses will not increase in direct proportion to the 
increase in location and associated revenues and profits.  This correctly 
assumes that the infra-structure required to support the operations such as 
upper management, financial etc. are already in place and have excess 
capacity capable of handling the planned expansion.  Per the Debtors 
projections, the amounts of average monthly net operating profits of 

                                     -13-

<PAGE>

$28,096 for the second twelve month period ("Year 2") is based on increasing 
the number of locations by one during this period (total seven), with the 
average number of operating locations during the year computed as 6.42.  Per 
the Debtors projections, the amounts of average monthly net operating profits 
of $37,558 for the third twelve month period ("Year 3") is based on 
increasing the number of locations by two during this period (total nine), 
with the average number of operating locations during the year computed as 
7.67.  Per the Debtors projections, the amounts of average monthly net 
operating profits of $54,688 for the fourth twelve month period ("Year 4") 
is based on increasing the number of locations by three during this period 
(total twelve), with the average number of operating locations during the 
year computed as 10.75.

The average monthly net operating profit per the Debtors actual and 
projections are as follows:

                               Total Per Month     # of Centers   Per Center
                               ---------------     ------------   ----------
         August                    $20,440              6           $3,407
                              
         September                 $29,608              6           $4,935
                              
         October                   $37,219              6           $6,203
                              
         Full Year - 1995          $21,498              6           $3,583
                              
         Projection - Year 1       $21,220              6           $3,537
                              
         Projection - Year 2       $28,096              6.42        $4,376
                              
         Projection - Year 3       $37,557              7.67        $4,897
                              
         Projection - Year 4       $54,688             10.75        $5,087

This comparison of actual operating results in 1995 to the Debtors projected 
results, clearly indicates that the Debtors financial projections are 
reasonable.  The average monthly net operating profit per location assumed in 
the financial projections for Year 1 is $3,537; Year 2 is $4,379; Year 3 is 
$4,899 and Year 4 is $5,087.  The amount projected for Year 4 is lower than 
that already achieved by the Debtors in October 1995.  Based on all of the 
foregoing, I believe that the operating profits reflected in the financial 
projections are reasonable.  

    26.  In expressing concern regarding accounts payable increasing from 
March 1995 to August 1995 (paragraph 22, (a) (b) & (c)) CVD is choosing to 
ignore the fact that the operations of the Debtors

                                     -14-
<PAGE>

did not generate significant profits during this specific period due to the 
unexpected and unusual action taken by Alpha Therapeutics as described in 
paragraph 17, which is reiterated below.  This reduction reflects the fact 
that Alpha Therapeutics, for the first time in ten years, exercised its 
contractual option to decrease its purchase of source plasma volumes by 
twenty five percent (25%), for six months.  This adversely impacted the 
earnings for this period. The Debtors management used this opportunity to 
negotiate a CMV hyperimmune program and a Tetanus hyperimmune stimulation 
program with North American Biologicals, Incorporated; thus, more than 
compensating for the twenty five percent (25%) shortfall in volume, at a 
$2.00 per liter increase in margin for Tetanus and an $8.00 per liter 
increase in margin for CMV hyperimmune plasma. The time it took to initiate 
the hyperimmune programs negatively impacted earnings; however, as can be 
seen, beginning with September 1995, the earnings recovered to near first 
quarter historical actual for early 1995.  The new contract with Alpha 
Therapeutics beginning January 1996, includes a lower maximum reduction 
possible of ten percent (10%) instead of the previous twenty five percent 
(25%).  The resulting decrease in cash flow led to the increase in accounts 
payable, the eventual payment of which is clearly contemplated and addressed 
in the Debtors PROPOSED PLAN.

    27.  Based on all of the foregoing it is my opinion that the issues and 
concerns raised by CVD are without merit and are clearly unsupported by the 
facts available relating to the actual operating results and profitability of 
the Debtors.

ESTIMATED TOTAL COLLECTIVE VALUE OF THE STOCK OF AVRE AND BINARY

     28.  I have performed a business valuation to estimate the collective 
value of the stock of AVRE and Binary and have found this to be in excess of 
$2,000,000 (see Exhibit 4 and 5).  For this business valuation, I have 
selected an income approach of business valuation which discounts the 
projected net cash flows of the business to their present value.  This method 
handles expected uneven income or cash flow streams, unusual lump sum 
payments, new centers and the likes, thus is particularly suitable to the 
Debtors business.  Additional reasons for selecting the income method were 
the unsuitability of the asset based methods for a business of this type the 
lack of availability or reliable comparable data for this type of small 
privately owned businesses in a rather specialized market niche.

                                     -15-

<PAGE>

The latter fact precluded the effective use of a market comparable method. 
Another available method, the asset based method is unsuitable for a non 
capital intensive business with significant characteristics of a service 
business.  The base information for use in such a discounted cash flow method 
are reasonable financial projections.  I have reviewed the Debtors financial 
projections and have found these to be reasonable.  The Debtors financial 
projections contain the expenses attributable to ABI as the parent company of 
AVRE and Binary.  In preparing this business valuation, I have assumed that 
these expenses fairly reflect the expenses that would be incurred by AVRE and 
Binary if they were to operate as independent entities.  Therefore my 
collective business valuation of AVRE and Binary is based on the Debtors 
financial projections.  No other allowances need to be made for ABI, since 
ABI is not projected to generate any revenues other than through the 
operations of AVRE and Binary.
 
    29.  In arriving at the estimate of business value, I have estimated that 
the return an investor would require for a business of this type would be 
approximately 21%.  This consists of two components, the risk premium and 
the safe rate of return.  I estimated the risk at 15% by evaluating the risk 
environment of the Debtors.  I considered amongst other factors, competition, 
management ability and depth, profitability and stability of earnings and 
financial strength of both AVRE and Binary.  The current risk free rate of 
return is estimated at 6.25% based on the quoted value (Wall Street Journal - 
12/18/95) of the Lehman Brothers Long Term T-Bond rate. This reflects the 
nearest equivalent to a long term safe investment return currently available 
in the marketplace.  Based on all of the above, the total return likely to be 
anticipated by an informed investor ( the discount rate) is estimated as 
21.25% (15% + 6.25%).  This expected rate of return was used in discounting 
back to the present value, the projected future cash flows of the Debtors.  
Furthermore, I have estimated that the long term real growth rate (i.e. 
growth rate without any allowance for inflation) after Year 4 onwards will be 
6%.  The long term inflation rate based on all available current economic 
data in the marketplace, is estimated at 3%.  Therefore the total long term 
growth is computed as 9% (6%+3%).  The capitalization rate was computed as 
12.25% by taking the estimated discount rate less long term growth rate 
(21.25% - 9%) and was used in computing the terminal value (i.e. the value of 
the business at the end of year 5 which reflects all of its earning potential 
from Year 5 onwards, as a going concern).  Please

refer to Exhibit 4 and 5 for details of the business valuation computation, 
reflecting the collective value of the stock of AVRE and Binary in excess of 
$2,000,000.

CONCLUSION

    30.  Based on all of the foregoing it is my opinion that the underlying 
assumptions on which the Debtors financial projections are based, are 
reasonable and the PROPOSED PLAN is viable with respect to these aspects.  
Based on the future outlook as portrayed in the Debtors financial 
projections, I believe that the estimated collective value of the stock of 
AVRE and Binary is in excess of $2,000,000.  It is my opinion that the 
issues and objections rasied by CVD relating to the financial viability of 
the plan were found to be without merit, as addressed in detail above.  The 
financial projections were prepared by the Management of the Debtors and are 
based upon assumptions which I believe to be reasonable.  Nevertheless, no 
assurance can be given that any of the results or events  described in the 
PROPOSED PLAN and the Debtors financial projections will occur in the manner 
stated and at the predicted times.  Actual results may vary from projected 
results.

    I declare, under penalty of perjury, that the above is true and correct. 
Executed the 28th day of December, 1995 at Los Angeles, California.

                                   SeraCare
                   Assumptions Underlying Four Year Forecast

The attached financial forecast were prepared by management of SeraCare and are
based upon assumptions which management believes are reasonable.  Nevertheless,
the attached financial forecast are based upon assumptions which may or may not
prove to be accurate or appropriate.  No assurances can be given that any of
the results or events described herein will occur, or that if they do occur,
they will occur at the predicted times.  Actual results may vary widely from
projected results.  Accordingly, the financial forecasts should not be relied
upon to indicate the actual results which will be attained by SeraCare during
the forecasted periods.

The four years  forecasted herein have been predicated on meeting the Company's
strategic objective of expanding the business through internally generated cash
flow.  To this end, the forecast illustrates how additional plasma centers can
be acquired during the four year period.  While there is no particular reason
why such acquisitions can not be made, there can be no guarantees that they
will be made or that the results will be presented herein.

Other assumptions are as follows:

1.   The assumed rate of acquisition is reflected on the projected Statements
     of Income attached herewith.

2.   The attached forecasts assume that production from acquired centers  
     will be sold domestically at approximately the same prices as currently
     being received. 

                                    EXHIBIT C

                            EXHIBIT 6 PAGE 1 OF 15


<PAGE>

3.   It is expected that by January  1996, 25% of the plasma collected      
     (approximately 25,000 annually) will be hyperimmune and will yield a $3.00
     to $8.00 premium per liter over source plasma.

4.   The cost of acquired centers is assumed to be $200,000 each with 
     fixed assets of $90,000, goodwill of $60,000, and net current assets of
     $50,000.  It has been assumed that all acquisitions will be made for cash
     with no financing.

5.   Goodwill has been amortized over 17 years consistent to the AICPA 
     pronouncement.

6.   After considering the impact of the "1986 tax act", taxes have been
     calculated based upon the assumption that the current loss carry-forward
     of approximately $6.5 million will be available to SeraCare at the rate of
     $150,000 per year for 15 years.  Under the provisions of the 1986 tax act,
     such an assumption may or may not be valid depending upon the ultimate
     determination of ownership, control and business activity.

7.   The basic framework of this presentation is that a net of $.995 million is
     received by SeraCare and used as follows:

                                December 7, 1995

To:  UNSECURED CREDITORS OF AMERICAN BLOOD INSTITUTE, AVRE INC. AND   
     BINARY ASSOCIATES, INC.

    We have been counsel to the  unsecured creditors committee since the 
inception of these cases.  The Committee has monitored all of the debtors' 
prior efforts to  formulate a plan of reorganization that would  permit 
unsecured creditors of the three debtors  to receive a reasonable dividend.

    The Committee believes  that the plan of reorganization  that accompanies 
the enclosed disclosure statement is  the last opportunity that unsecured 
creditors will have to receive any recovery.

    Those creditors who have been following  the activities in this case are 
aware of the fact that  CVD Financial has been granted relief from the 
automatic stay provisions of the Bankruptcy Code.  If the debtors' proposed 
plan of reorganization is not confirmed, CVD will undoubtedly move forward to 
foreclose on its collateral and as a result,  the unsecured creditors of all 
three debtors  will receive nothing.

    The Committee recommends that the proposed plan of reorganization be 
confirmed and it urges all unsecured creditors to vote in favor of the plan. 
To do so, creditors must indicate their acceptance of the plan on the  
enclosed ballot and return it to the attorney for the debtors in the 
envelope that  has been provided.  Ballots must be received by December 29, 
1995 to be counted. However, in order to forestall CVD's foreclosure 
action it would be helpful if you returned your ballot by December 19, 
1995. Therefore, we ask that you give this matter your immediate attention 
and mark and return your ballot today.

                                     Very truly yours,

                                     KATZ, HOYT, SEIGEL, & KAPOR

claims in each class and the holders of two-thirds in amount of equity 
security interests in each class voting on the Plan.  In the event the 
requesite acceptances are not obtained, the  Court may nevertheless confirm a
plan if the Court finds  that the Plan accords fair and  equitable treatment 
to the Class rejecting it.  To have your vote count, you must complete and 
return this Ballot.

                                 INTRODUCTION

     Contemporaneously with this Disclosure Statement, American Blood Institute,
Inc. ("ABI"), AVRE, Inc. ("AVRE") and Binary Associates, Inc. ("Binary"),
Debtors in Possession herein (collectively the "Debtors") have filed with the
Bankruptcy Court a proposed Third Amended Joint Plan of Reorganization (the
"Plan").

     The Plan herein provides for the continued operation of the Debtors under
the new name SeraCare, Inc. ("SeraCare").  Having divested its unprofitable
whole blood collection business, SeraCare will concentrate on operation and
development of its plasma collection centers.

     Under the Plan, Unsecured Creditors of ABI will receive approximately 10%
of the allowed amount of their Claims, a pro rata distribution of 10,000 shares
of Reorganized ABI's  (SeraCare's) common stock and fifty percent of any net
affirmative recovery received by the Debtors against recipients of avoidable
transfers.  Holders of Unsecured Notes of ABU will receive securities in
Reorganized ABI.  Holders of equity interests of ABI will not receive any
distributions.  General unsecured creditors of AVRE and Binary will receive cash
distributions totaling 80% of the allowed amount of their claims. 

                                      II.

                       VOTING AND CONFIRMATION PROCEDURES

     After notice and hearing, this Disclosure Statement was approved by the
Bankruptcy Court as containing adequate information in sufficient detail to
enable the Holders of Claims against the Debtors to make an informed judgment
about the merits of approving the Plan of Reorganization.

     THE PLAN OF REORGANIZATION IS SET FORTH IN FULL IN EXHIBIT "A" TO THIS
DISCLOSURE STATEMENT.  EACH RECIPIENT OF THIS DISCLOSURE STATEMENT IS URGED TO
REVIEW THE PROVISIONS OF THE PLAN OF REORGANIZATION FULLY PRIOR TO REVIEWING
THIS DISCLOSURE STATEMENT.

     The Bankruptcy Court will set a hearing on the Confirmation of the Plan of
Reorganization after Creditors have voted.  Creditors may vote on the Plan of
Reorganization by filling out and mailing the accompanying Ballot for Accepting
or Rejecting Plan of Reorganization to Douglas D. Kappler of Robinson, Diamant,
Brill & Klausner, A Professional Corporation, 1888 Century Park East, Suite
1500, Los Angeles, California 90067.  In order for Creditors' votes to count,
ballots must be received on or before December 29, 1995.  The Debtors will file
the ballots timely received with the Bankruptcy Court.

Each Creditor is entitled to vote for or against the Plan.  As a Creditor your
vote is important.  The Bankruptcy Court cannot consider Confirmation of the
Plan or Reorganization until acceptance thereof has been

                                      -1-


                              EXHIBIT B  PAGE 93

obtaining pursuant to the affirmative vote of each impaired class of Creditors
who holds at least two-thirds ( 2/3 ) in dollar amount and more than one-half
(1/2) in number of the allowed Claims of such classes voting on the Plan of
Reorganization.  Following acceptance, the Bankruptcy Court will hold a hearing
on the Confirmation of the Plan of Reorganization and will enter an Order of
Confirmation with respect to the Plan of Reorganization if it finds that, among
other things, all payments to be made by the Debtors in connection with the case
or Plan of Reorganization have been disclosed to the Bankruptcy Court; each
class of Creditors has accepted the Plan of Reorganization or is not impaired by
the provisions thereof, and that Confirmation is nor likely to be followed by
the liquidation or need for further financial reorganization of the Reorganized
Debtor.


     The Plan of Reorganization may be confirmed even if it is not accepted by
all of the classes of Creditors if the Bankruptcy Court finds that the Plan does
not discriminate unfairly against and is "fair and equitable" as to such class
or classes.  This provision, set forth in Section 1129 (b) of the Bankruptcy
Code, requires that, among other things, the claimants in the impaired classes
must either receive the full value of their Claims or, if they receive less
than the full value of their Claims, no class with junior liquidation priority
may receive anything and no senior claimant may receive more than full payment. 
Section 1129 (b) is a complex provision and this summary is not intended to be a
complete statement of the law.  The Debtor will elect to rely upon this
provision to seek Confirmation of the Plan if it is not accepted by each
impaired class of Creditors. 

     NO REPRESENTATIONS CONCERNING THE DEBTORS' FINANCIAL CONDITION, THE PLAN OF
REORGANIZATION, OR THE VALUE OF THE ASSETS TO BE LIQUIDATED PURSUANT TO THE PLAN
ARE AUTHORIZED BY THE DEBTORS OTHER THAN AS SET FORTH IN THIS DISCLOSURE
STATEMENT.

whole blood business, it was determined that (a) the Company had lost
significant sums of money, (b) the whole blood business in California was too
cost intensive, and (c) the Plasma business presented an opportunity to build a
significant operation relatively quickly.  As a result, the blood collection
activities were ceased and six (6) plasma collection centers were acquired.  The
Company currently owns and operates six such centers.

     ABI filed for reorganization under Chapter 11 when CVD Financial
Corporation ("CVD") commenced foreclosure upon ABI's assets.  The Company is
completing its operational turnaround, and has filed its Second Amended Chapter
11 Plan or Reorganization together with this Disclosure Statement.

     2.   THE PRODUCT.

     ABI's product is source plasma.  It is the strategy of ABI to build its 
source plasma operation via acquisition of ABRA Quality Plasma Program (QPP) 
certified plasma centers throughout the United States and then convert 
certain of its facilities to the collection of hyperimmune plasma; however, 
for the purposes of this statement source plasma will be the only product 
discussed. Source plasma is collected from humans, and is the liquid part of 
blood. When plasma is donated during a procedure similar to that of giving 
blood, the clear plasma is mechanically separated from the cellular elements 
of the blood, with the later being returned to the donor. Plasma carries many 
needed substances including valuable proteins and antibodies.  After 
donation, the plasma is shipped to pharmaceutical manufacturers who 
fractionate (separate) the proteins and antibodies as part of processes to 
manufacture a large number of both therapeutic and diagnostic products.  
These products are used throughout the world to prevent and treat illnesses 
and to treat injuries. Plasma products are the fastest growing segment of the
blood products industry and also provide vital raw materials for medical and 
biotechnology research and development.

     3.   THE INDUSTRY AND THE MARKET.

     There are currently approximately 440 plasma collection centers located
across the United States which supply 65% of the world's plasma needs.  These
collection centers, which are protected under the blood immunity statutes, sell
their plasma to fractionators of which the top five are located in the United
States.  Four of these five are large international companies.  Commercial
source plasma operations are relatively new,  beginning in the early 1960's. 
The industry has grown rapidly and for the past few years, collection has
averaged around 7.5 million liters within the United States.  Of this amount,
approximately 4.5 million liters is collected by or sold to major fractionators
in the U.S.  Such plasma is usually sold under a long term contract, with the
fractionator paying the cost of testing and soft goods.(1)  The balance is sold,
often through brokers into the spot market to

- ------------------

    (1) Soft goods are items such as containers, tubing and other materials 
which are consumed during the plasma collection process.  Testing consists of
assays to ensure that collected plasma is free from infection with, for example,
Hepatitis A, B & C and the HIV viruses.

                                      - 3 -


                              EXHIBIT B  PAGE 95


<PAGE>

(usually) European customers.  Plasma contracted to U.S. fractionators 
typically sells for between $40 and $48 per liter.  Spot market plasma sells 
for approximately $76 per liter.  The cost of producing plasma for the spot 
market, however, must include the price of testing and soft-goods (currently 
around $29 per liter).

     4.   QUALITY PLASMA PROGRAM (QPP) CERTIFICATION.

     Within the past five years, American Blood Resources Association (ABRA), 
the plasma industry trade association with self-regulatory powers, has 
created a certification called Quality Plasma Program (herein called "QPP"). 
The QPP certification program has been successful in upgrading the United 
States plasma collection industry in that a QPP certification of a Plasma 
Center requires that the centers follow strict rules including facilities 
upgrade, high operating standards, minimum FDA citations, strict donor 
screening for drug and disease, bona fide addresses for donors, etc.

     The result of the QPP program is that non-QPP plasma is less and less
desirable in the world plasma market.  United States QPP plasma is considered to
be of a high quality worldwide, thus, providing product differentiation based
upon quality in the world market for United States collected plasma.

     When ABI purchased AVRE and Binary, none of the six centers were QPP
certified.  Under the current management, the Company has received QPP
certification for all of its six centers.

     5.   CURRENT OPERATIONS.

     ABI's six plasma collection locations were the result of an acquisition of
two companies: AVRE, Inc. ("AVRE") and Binary Associates, Inc. ("Binary"). These
facilities owned by AVRE and Binary currently collect approximately 9,500 liters
of plasma per month.  Approximately 30% of this product is currently sold under 
a long-term contract to Alpha Therapeutics,  a subsidiary of Green Cross of
Japan.  Approximately 60% of the production is sold through brokers to European
fractionators.  The balance represents tetanus and CMV hyperimmune plasma which
is sold domestically.  Forecasted pretax profits before bankruptcy and
extraordinary expenses for the year ended December 31, 1995 are estimated at
$300,000.2/

     6.   BUSINESS STRATEGY.

     ABI believes there is an opportunity to improve the profitability of the
present centers.  To this end, management has been involved in re-negotiating
plasma contracts on more favorable terms as they come due, and has been working
to increase the operating efficiency of the individual centers.  The Company
also intends to expand by purchasing additional centers through the use of
warrants, a secondary offering or other financial vehicles available at the
discretion of the Board of Directors.  It is also felt that operations will
generate significant amounts of cash annually which can ultimately be

     2/   ABI currently has a tax loss carry-forward of approximately $6 
million. Therefore the company does not expect to pay tax on income until 
1996.

<PAGE>

invested in additional centers or into derivative businesses including
hyperimmune plasma collection.

     7.   MANAGEMENT.

     ABI has assembled an experienced management team including individuals with
many years' experience in source plasma collection, business turnaround
management, strategic business planning and corporate finance.

B.   BACKGROUND.
     
     American Blood Institute was founded and incorporated with its original
purpose to enter the blood collection and distribution business on a "for
profit" basis.  Originally conceived as a "Blood Bank" with national roll-out
potential, ABI lost significant sums of money until 1993, when following an
analysis of the company and the industry, new management decided that the
original business was:

     a.   Overly complicated,
     
     b.   Too highly regulated, and

     c.   Not economically feasible in California as a "for profit" business.

     At that time, the strategic direction of the Company was changed whereby 
it was determined to acquire a core group of plasma collection centers and 
ultimately to discontinue the whole blood operations. ABI acquired AVRE and 
Binary and immediately entered into renegotiations of the plasma sales 
contracts, began developing marketing strategies including demographic 
studies and donor pricing analysis, applied for QPP designation on five of 
the six centers, and began to establish consistent policies and strategies in 
order to compete in the emerging QPP Plasma industry.

     For the fiscal year ending December 31, 1993, ABI lost approximately $2.7
Million.  For the fiscal year ending December 31, 1994, ABI, AVRE and Binary
broke even before extraordinary and chapter 11 expenses.

     1.   OWNERSHIP. 

     ABI common stock is currently held by the following entities.

Gerant Industries, Inc.                                25%

Conversion Industries, Inc.                            28%

Essex Venture Partners, L.P.                           17%

Others                                                 30%

Alfred Jay Moran, Jr., Chairman of the Board and President of Gerant, is
Chairman, President and CEO of ABI.

     2.   HISTORY OF THE PLASMA CENTERS.

     In 1976, Binary was started by Dale Gallinatti and Larry Carey (both of
whom are no longer with the company) with one plasma center located in Nogales,
Arizona.  The owners later added a second corporation, AVRE.  Over


                                      -5-


                              EXHIBIT B  PAGE 97

<PAGE>

the years, the two corporations had as many as ten plasma centers, but by 1993
the number had been reduced to six.  In October 1993, ABI purchased both Binary
and AVRE for $1 million.  The purchase was made with a $1 million loan from CVD
which was guaranteed by Company Industries, Inc.  ("Conversion").  Gerant owned
over 60% of the  Company prior to the CVD loan, but was required to give  1/2 of
its ownership in ABI as a fee to Conversion in order to obtain the financing.  

C.   THE MARKET.

     The blood resource industry can be divided into two industry segments.  
One is the non-profit or voluntary whole blood sector which is commonly 
thought of as Red Cross or regional blood centers.  The other is the 
commercial or for-profit  segment as plasma collection centers. 

     The non-profit sector is primarily concerned with providing whole blood and
components of blood for transfusion in medical applications.

     The for-profit commercial sector commonly collects plasma from paid donors
and sells this source plasma to fractionators who then produce plasma products
or fractions which are used in the prevention and/or treatment for various
illnesses and injuries.

     The U. S. plasma industry has continued to expand rapidly, and in 1990
there were about 50,000 donor collections per day.  This total came from a donor
pool of just over 1 million individuals.  There were 23 new licensed source
plasma centers opened in 1989 and 22 more in 1990 bringing the total to 440
located in the U.S.

     The commercial U.S. source plasma centers collected over 7 million liters
of plasma.  The market is structured among centers owned by both foreign and
U.S. fractionators and by independent companies who sell to diagnostic companies
and other fractionators.

     Because of its position as a world leader in medicine and medical biotech
development, the United States plays the leading role in supplying the world's
source plasma.  This is due to our superior health standards and our seeming
obsession with a high degree of regulation resulting in a superior source plasma
product.  The United States commercial sector provides 65% of the world's plasma
needs.

D.   BUSINESS STRATEGY. 

     The fundamental elements of the strategy which underlie the Debtors'
forecast are:
          
          a.   Managing the existing centers effectively to increase 
operating efficiency and monthly volume

          b.   Upgrading all facilities to meet recent industry quality 
standards for plasma collection centers (QPP standards).

                                      -6-


                              EXHIBIT B  PAGE 98

<PAGE>

          c.   Paying close attention to trends in the plasma market in order to
maintain an optimum mix of contract and spot market sales.

E.   OPERATIONS.

     The Debtors currently operate six plasma centers at the following
locations:

     *    Clarksville,  Tennessee

     *    Colorado Springs,  Colorado (2 centers)

     *    Las Vegas,  Nevada

     *    Phoenix,  Arizona

     *    Pueblo  Colorado

     These locations are forecasted to collect approximately 105,000 liters of 
plasma in calendar year 1995.  This represents an increase of approximately 
26,000 liters over 1993 and 10,000 liters over 1994.  Management expects to 
see continued growth resulting from better marketing (donor recruitment) 
practices, better customer service (donor throughput), more attention to the 
yield of plasma per donor and increased margins from the Company's hyperimmune 
plasma programs.

     1.   MANAGEMENT.

     ABI is headquartered in Los Angeles, California and operates with a small 
head office staff in addition to the employees at the collection centers. 

     The Board of Directors will be comprised of five members.  The members 
will be: Alfred Jay Moran, Jr., Chairman, President and Chief Executive 
Officer of ABI and Samuel Anderson, former Chairman and Chief Executive 
Officer of Alpha Therapeutics.  The three remaining Board Member positions 
will be selected by the purchasers of the $1.2 million in Debtor's Notes (the 
"Investor Group").

     2.   REGULATORY ISSUES.

     The plasma collection and derivative industry is one of the most heavily 
regulated in the United States.  Federal, state and local regulation are 
basically designed to protect the health of the donors as well as the 
integrity of the products.  Although the Food and Drug Administration 
administers the particulars of the Code of Federal Regulations rather evenly 
across the country, patchworks of state and local regulations can be, in some 
cases, very restrictive.  In recent years, as a result of some "less than 
perfect" practices in the blood and plasma industry, the FDA has become much 
more focused on plasma centers and blood banks in general.  Recent history has 
demonstrated this by the actual closing of a number of blood banks and plasma 
centers in the United States because of legal action taken by the FDA.  The 
Company's management has, and will continue to, closely monitor the compliance 
with regulations as well as with overall quality assurance standards.

                                      V.

                     REASONS FOR FILING BANKRUPTCY CASES 

     Because of six years of losses in the whole blood collection and 
distribution business and their accumulated debt, new management decided to 
effect a strategic refocusing of operations via an effort to reorganize 
voluntarily outside of bankruptcy.  That effort was initially agreed to by 
CVD which later attempted to foreclose on ABI's primary assets thereby 
forcing ABI to file for protection under the provisions of Chapter 11 of the 
Federal Bankruptcy Laws in order to complete its reorganization plans.  
Voluntary petitions under chapter 11 were filed by ABI, AVRE and Binary on 
January 7, 1994, after CVD, the Debtor's primary lender, declared a default 
under its loan agreements.

                                     VI. 

               SIGNIFICANT EVENTS DURING THE CHAPTER 11 PROCEEDINGS

A.   GENERAL.

     Following the filing of the Debtors' petitions seeking reorganization 
under chapter 11 of the Bankruptcy Code, the Debtors have operated their 
businesses as debtors in possession.

     The Bankruptcy Court has certain supervisory powers over the operations 
of the Debtors during the reorganization.  These powers generally consist of 
reviewing and ruling upon any objection raised by a party in interest to 
business operations or proposed transactions of the Debtor.  Except as 
otherwise authorized by the Bankruptcy Court, the Debtors have given notice or 
any transactions not in the ordinary course of business, and of any other 


                                    - 9 -


                              EXHIBIT B  PAGE 101

<PAGE>

matters that require notice pursuant to Bankruptcy Court Rules or as ordered 
by the Bankruptcy Court.  In addition, the Bankruptcy Court has exercised 
supervisory powers in connection with the employment of attorneys and other 
professionals.

B.   APPOINTMENT OF CREDITORS COMMITTEE.

     Shortly after the commencement of the ABI's Chapter 11 case the United 
States Trustee appointed an Official Committee of Unsecured Creditors (the 
"Committee") pursuant to Bankruptcy Code Section 1102.  The Committee consists 
of Belle Bonfile Memorial; Blood Bank of Alaska, Inc.; Blood Systems, Inc.; 
Central California Blood Banks; Lifesource Blood Services; and Oklahoma Blood 
Institute.

C.    RETENTION OF PROFESSIONALS.

     The Committee has retained Katz, Hoyt, Seigel & Kapor as its attorneys. 
ABI and its counsel have been in frequent communication with the Committee and 
have kept the Committee regularly informed concerning the operation of the 
ABI's business and other matters of interest to the Committee.

     During the course of its chapter 11 proceedings, the Debtors have 
employed pursuant to authority granted by the Bankruptcy Court various 
professional to assist it in these Chapter 11 proceedings and in conducting 
its ongoing operations.  The Debtors employed Robinson, Diamant, Brill & 
Klausner as bankruptcy counsel; Tilles, Webb, Kulla & Grant as special 
corporate counsel; Fisher & Phillips as special litigation counsel; and Samuel 
T. Anderson and Stephen Wyle as management consultants.

D.   PAYMENT OF PRIORITY WAGES.

     AVRE and Binary, along with their parent company ABI, filed their 
voluntary petitions under chapter 11 of the Bankruptcy Code on January 7, 
1994.  At that time, the payroll of approximately 72 employees of  AVRE and 
Binary for the period from December 31, 1993 through January 7, 1994 was due 
on January 21, 1994.  Accordingly, AVRE and Binary each brought motions for 
permission to pay prepetition priority wages that had accrued as of the 
petition date.  The motions were granted on an emergency basis thereby 
allowing AVRE and Binary to remain in business without loss of staff for 
failure to pay wages.  Total amounts of gross employee compensation paid to 
the Binary and AVRE employees pursuant to order of Court were $13,246.07 and 
$6,323.85, respectively.

E.   JOINT ADMINISTRATION OF CHAPTER 11 CASES.

     Early in the case ABI, AVRE and Binary jointly moved the Bankruptcy Court 
for an order authorizing joint administration of their Chapter 11 cases.  
Since three Debtors were and still are, respectively, a parent company and its 
two wholly owned subsidiaries, whose business operations are conducted under 
common management and with consolidated administrative and operation 
functions, it made sense that the three cases be jointly administered.  
Furthermore, the three Debtors have in common a single secured creditor group, 
whose claims on any of the three bankruptcy estates arise out of and relate to 
the same events, transactions and documents.  Accordingly,


                                     -10-


                              EXHIBIT B  PAGE 102

<PAGE>

the Court entered an order for joint administration of the above-named 
bankruptcy cases thereby avoiding duplication of costs and expenses and 
needless complication in the administration of these three matters.  The order 
for joint administration further provided for the non-allocation of time 
expended by professionals for each of the Debtors and such other professionals 
whose employment is approved by the Court.

F.   EXTENSION OF EXCLUSIVITY.

     Before expiration of the exclusivity periods provided by Bankruptcy Code
Section 1121 (b), which gives a debtor an exclusive right to file and confirm a
plan of reorganization, the Debtors moved on several occasions for extensions of
such periods.  The latest extension of exclusivity ended in July, 1995, and the
Debtors did not seek to have it extended further.

G.   UNEXPIRED LEASES AND EXECUTORY CONTRACTS.

     The Debtors have also sought and obtained extensions of time within which
to assume or reject certain nonresidential leases of real property.  Currently
the Debtors intend to assume the leases for the following business locations:
611 North Las Vegas Boulevard, Las Vegas, Nevada; 1174 Fort Campbell Boulevard,
Clarksville, Tennessee; 129 and 141 North Spruce, Colorado Springs, Colorado;
and 411 and 413 West 4th Street, Pueblo, Colorado.  The Debtors are current on
all of their obligations under the foregoing leases.

H.   SALES OF PROPERTY.

     Prior to bankruptcy, ABI discontinued its business operations consisting of
collecting and distributing whole blood and blood components.  As a result, ABI
owned certain equipment, furniture and inventory that could be sold.  Prior to
bankruptcy, ABI had received offers to purchase some of its personal property. 
Following bankruptcy, ABI sought and obtained permission of the Bankruptcy Court
to consummate the proposed sales.  Later, ABI sought and obtained permission of
the Bankruptcy Court to sell the balance of its equipment and furniture provided
that the total sales price for such property was at least fifty percent (50%) of
its value as estimated by Evaluation Counselors, a professional appraisal
company.

I.   DEBTOR FINANCING.

     By order entered September 21, 1994, the Bankruptcy Court authorized ABI to
obtain up to $4.5 million in credit through the issuance of Debtor's Notes.  The
order provides, among other things, that Debtor's Notes carry an interest rate
of 12%, allows superiority over other administrative claims and provides for the
payment of certain finders' fees.

     ABI initially attempted to place the Notes through Relco Corporation
("Relco"), an investment banking firm primarily engaged in restructuring and
financing companies in chapter 11.  Relco was unable to place the Notes, and ABI
was forced to turn to other sources.


                                     -11-


                              EXHIBIT B  PAGE 103

<PAGE>

     More recently, ABI has received a best efforts commitment from First 
Equity Capital Securities, Inc.  ("First Equity") to place $1.2 million in 
Debtor's Notes with its clients, which will net approximately $1 million to 
ABI, an amount sufficient to fund the Third Amended Plan of Reorganization 
described herein. (1) ABI has filed a motion wherein it is seeking an order of 
the Bankruptcy Court modifying some of the terms of the Debtor's Notes.  
Copies of the commitment letter and the firm resume of First Equity are 
attached hereto collectively as Exhibit "B".

J.   MOTION  FOR RELIEF FROM STAY BY CVD.  

     Prior to the commencement of the within cases CVD entered into a financial
transaction with ABI wherein CVD granted ABI a line of credit and term loan
secured by a first priority lien against the accounts receivable, inventory and
equipment of ABI, AVRE and Binary.  Additionally, the CVD line of credit and
term loan were secured by the common shares of AVRE and Binary.  On or about
July 7,1995, CVD filed a motion for relief from stay seeking permission to
foreclose on its liens and security interests in the property of the Debtors. 
By order of the Bankruptcy Court, CVD's motion was granted effective January 2,
1996.

K.   STIPULATION RE ADMINISTRATIVE CLAIM OF DRS. FRISCH AND GOLDING.

     In or about October 1995 the Debtors entered into a stipulation with the
Committee and Doctors David M. Frisch and Arthur Golding (the "Doctors") wherein
the Debtors agreed to reimburse the Doctors for all of their expenses incurred
in assisting the Debtors and the Committee in opposing CVD's motion for relief
and in connection with the Doctors' efforts to structure a plan involving the
Doctors' purchase of the Debtors' assets.  The stipulation which is subject to
Bankruptcy Court approval provides for an administrative claim in favor of the
Doctors in an amount up to $42,000 for such expenses.  The administrative claim
may be increased under certain circumstances but in no event will such claim
exceed $100,000.

L.   MISCELLANEOUS.

     Pursuant to an order of this Court entered April 19, 1994, June 30, 1994
was set as the last day to file proofs of claims or other interests in these
cases.

- -------------------

     (1)  A prior plan contemplated a national buildout of up to 42 centers,
utilizing the major portion of the proceeds from the $4.5 million in Debtor's
Notes authorized by the Court for the buildout.  The current Plan does not
incorporate a national buildout in its projections thereby substantially
decreasing the cash needs of the Debtor.  However, the Reorganized Debtor
intends to expand post-confirmation by purchasing additional centers through the
use of warrants, a secondary offering, or other financial devices available at

                                     VII.

                               SUMMARY OF PLAN

     The Plan is attached as Exhibit "A" to this Disclosure Statement.  The
Plan, if confirmed, will constitute a legally binding agreement between the
Debtor and the holders of claims, and it is therefore important for you to
understand its provisions.  Holders of claims are urged to discuss any 
questions they may have with their respective counsel and/or accountants.  

     The Reorganized Debtors will consist of ABI, AVRE and Binary.  AVRE and
Binary will continue to operate as wholly owned subsidiaries of ABI.  ABI will
continue in business under a single new name SeraCare, Inc. ("SeraCare"). 
SeraCare ("Reorganized ABI") will be involved in the business of owning and
operating plasma collection centers.  The Plan thereby contemplates 
preservation of ABI's net operating loss carry forward, which exceeds 
$6,000,000.

     For purposes of the plan, the Debtors have divided their creditors into
different classes of claims and interests.  Essentially, the Plan proposes to
treat creditors as follow:

     1.   ADMINISTRATIVE PRIORITY CLAIMS.

     All professionals who have been rendering services to the Debtors or the
Committee in these cases will be paid in full in cash as and when allowed by 
the Court.  The Debtors estimate these costs and expenses at $195,000, 
including the claim of Doctors Frisch and Golding (SEE Article VI.K 
hereinabove).  All unpaid expenses of operation of the Debtors post-petition 
will be paid pursuant to normal business terms.  Additional Administrative 
Claims include Debtor's Notes issued or to be issued in the face amount of 
$1,200,000;  compensation to management consisting of 189,495 shares of 
Reorganized ABI and 126,300 options to purchase shares of Reorganized ABI 
to Alfred Jay Moran, Jr., Jerry L. Burdick  and Brian Olson; investment 
banker fees to First Equity of $90,000 plus reimbursement of expenses 
including legal fees; finder's fees to Anthony J.A. Bryan, Sr. Of $60,000; 
and finder's fees to Stuart Sundlun of $30,000.  Additionally, First Equity 
will receive 94,748 shares of common stock of Reorganized ABI, Anthony J.A. 
Bryan, Sr. 84,220 shares of common stock of Reorganized ABI and Stuart 
Sundlun 21,055 shares of common stock of Reorganized ABI. 

     Debtors' Notes shall be payable in accordance with their terms, and may be
converted to up to 1,610,708 shares of Reorganized ABI on or after the 
Effective Date.

     Upon confirmation of the Plan, as a bonus and for compensation for
management services rendered by Alfred Jay Moran, Jr., Jerry L. Burdick and
Brian Olson during the course of the Chapter 11 case Mr. Moran shall be issued
84,220 shares of Reorganized ABI's common stock and 56,147 options to purchase
common stock of Reorganized ABI.  Mr. Burdick shall be issued 63,165 shares of
Reorganized ABI's common stock and 42,110 options to purchase common stock of
Reorganized ABI., and Mr. Olson shall be issued 42,110 shares of Reorganized 
ABI's common stock and 28,073 options to purchase common stock

of ABI.  The exercise terms of the options are described in detail in Exhibit
"B" attached hereto.  The vesting date of the options will be the anniversary
date of the Effective Date.  The options will vest at the rate of one-third per
year and are contingent upon Reorganized ABI achieving certain projected
operating results.  Messrs. Moran, Burdick and Olson have filed Insider 
Compensation Request forms with the United States Trustee's Office requesting 
the stock and options as bonuses payable upon the successful confirmation of 
the Plan.  As set forth in those notices it is too speculative for the 
Debtors to estimate the value of the securities to be issued to management.  

     2.   TAX CLAIMS.

     The Plan proposes to pay pre-petition priority taxes in cash, in full on
the Effective Date or as soon thereafter as is practicable.  The Debtors
estimate that the total pre-petition  Tax Claims are approximately $5,000.

     3.   PRIORITY CLAIMS, CLASS 1.

     With the exception of pre-petition priority taxes and administrative
claims, all Claims entitled to  priority under Bankruptcy Code section 507 
will be paid in cash, in full on the Effective date.  The Debtors estimate 
that the total Priority Claims are approximately $11,500.

     4.   THE SECURED CLAIM OF CVD - CLASS 2.

     The secured claim of CVD, estimated by the Debtor to be approximately
$1,600,000, shall be paid down by $600,000 on the Effective Date.(1)  CVD shall
receive a replacement note for the balance of its claims payable over four 
years from the Effective Date, interest to accrue at the rate of 14% per 
annum on the unpaid balance.  The replacement note may be pre-paid at any 
time without penalty.  CVD shall maintain its present secured position, 
unless eliminated or altered by order of the Bankruptcy Court.  



__________________

     1/   The CVD claim is estimated by the Debtors not to exceed $1.6 
Million.  CVD filed a claim for $1,813,234.85 in June 1994, but it does not 
take into account certain payments made by the Debtors on account of assets 
liquidated by the Debtors or adequate protection payments made after the 
claim was filed.  The claim also includes a default rate of interest and 
certain other charges to which the Debtors intend to object.  Among other 
things, the Debtors contend that CVD is not entitled to a default rate of 
interest, attorneys' fees or other costs; CVD received preferential and 
fraudulent transfers;   CVD received avoidable post-petition transfers;  
CVD's claim should be equitably subordinated as a capital contribution 
disguised as a loan;  CVD wrongfully instituted foreclosure proceedings;  
and CVD breached the covenant of good faith and fair dealing.  The Debtors 
intend to pursue these and other claims and defenses against CVD 
post-confirmation.  The Debtors have requested a current accounting from CVD, 
but as of the date hereof have not yet received a response.  If, after 
objection to CVD's claim such claim exceeds the sum of $1,600,000, the 
replacement note given to CVD shall equal the difference between the Allowed 
Secured Claim amount and the sum of $600,000.

     5.   UNSECURED CREDITORS OF ABI - CLASS 3.

     Class 3 Claimants shall receive a pro rata distribution of the balance
remaining from the sum of $200,000 after payment of all Class 5 and Class 6
Claimants, up to a maximum of $.10 cash for each Claim dollar, payable as soon
as practicable after the Effective Date.  The Debtors estimate that Class 3
Claimants should receive a distribution of approximately 9-10% on  their 
Claims. Class 3 Claimants also shall receive 10,000 shares of common stock of
Reorganized ABI to be distributed on a pro rata basis as soon as practicable
after the Effective Date.  In addition, Class 3 Claimants shall receive for pro
rata distribution fifty percent (50%) of any "net affirmative recovery" 
received by the Debtors against recipients of avoidable transfers.  "Net 
affirmative recovery" means any cash  consideration actually received by the 
Debtors on account of an action brought against a creditor for an avoidable 
transfer, less costs and attorneys' fees incurred in obtaining such recovery. 
The Debtors estimate that Class 3 Claims total approximately $1,960,000 without
consideration of certain Claims which were filed as contingent or unliquidated.

     6.   UNSECURED NOTE HOLDERS - CLASS 4.
     
     Holders of Unsecured Notes totalling approximately $420,000 shall be
converted into 105,275 shares of Common Stock or Reorganized ABI.  All
distributions shall be made on a pro rata basis.

     7.   UNSECURED CREDITORS OF AVRE - CLASS 5.

     Unsecured Creditors of AVRE holding unsecured claims totalling 
approximately $5,000 shall receive eighty cents on the dollar in cash as 
soon as practicable after the Effective Date.

     8.   UNSECURED CREDITORS OF BINARY - CLASS 6.

     Unsecured Creditors of Binary holding unsecured claims totalling
approximately $9,500 shall receive eighty cents on the dollar in cash as 
soon as practicable after the Effective Date.

     9.   PREFERRED AND COMMON EQUITY INTERESTS OF ABI - CLASS 7.

     On the Effective Date all Preferred and Common Equity Interests of ABI
shall be deemed cancelled, annulled and terminated, and Holders of preferred
equity  Interests consisting of approximately 139,700 shares and common stock
consisting of 4,350,912 shares shall not be entitled to any distribution.

     All outstanding warrants shall be cancelled and the holders of warrants or
other equity claims not described above shall not be entitled to any
distribution.

     10.  COMMON EQUITY INTEREST HOLDER OF AVRE AND BINARY - CLASS 8.

     All of the issued and outstanding shares of AVRE and Binary are held by
ABI.  ABI shall retain its interests unimpaired.

the ordinary course on the Debtors' business.

                            MANAGEMENT OF REORGANIZED DEBTOR

A.   EXECUTIVE COMPENSATION.

    The executive officers of the Debtors are set forth in Paragraph 6.1 of
Article III, SUPRA, together with a brief statement of the background and
qualifications of each such officer.  The following table sets forth the key
officers and employees of Reorganized ABI and the annual salary to be paid on
confirmation of the Plan:

Name                          Position                      Salary
- ----                          --------                      ------
Alfred Jay Moran, Jr.         Chairman, President           $150,000
                              and CEO

Jerry L Brudick               Executive Vice President      $125,000
                              and CEO

Brian Olson                   Vice President                $ 90,000

There will be a quarterly salary adjustment whereby any pretax earnings over 
$100,000 per quarter shall be paid to the officers up to an annual maximum of
$25,000 to Mr. Moran, $10,000 to Mr. Burdick and $10,000 to Mr. Olson.  

    The officers of the Reorganized Debtors shall receive three year 
standard renewable contracts, copies of which are collectively attached 
hereto as Exhibit "C".  Also, a Management Bonus Plan will be established for 
the above-listed officers by the board of directors of Reorganized ABI 
whereby the Company will allocate ten percent of Pre-Tax Earnings which are 
in excess of $920,549 in year one after confirmation, $2,590,160 in year two, 
$4,384,187 in year three, $6,244,536 in year four and $8,166,636 in year five 
to a bonus pool to be paid to management pro rata based on salary level. No 
bonuses will be paid to management if the Debtors are in default under 
the Plan.  Based upon the four-year projections attached hereto as Exhibit 
"D" management would not be eligible for any bonuses.

                                       X.

                POST-REORGANIZATION OPERATION OF REORGANIZED DEBTORS

    Four (4) year financial projections have been prepared by management and
are attached as Exhibit "D".  The projections have been prepared in accordance
with generally accepted accounting principles and utilize the accrual method. 
Assumptions used in calculating the projections are as set forth below.



                                       -17-


                              EXHIBIT B  PAGE 109

<PAGE>

      These financial projections represent an estimate of future events that 
may or may not occur.  It is probable that some of the assumptions on which 
the financial projections are based will not materialize and that 
unanticipated events and circumstances will occur which will affect these 
projections. Therefore, there can be no assurance, and no representation or 
implication is made, that the financial projections or related assumptions 
will constitute an accurate reflection of the actual operating cash flow of 
the Reorganized Debtors during the periods indicated and the financial 
projections should not be relied upon as assurances of the actual results 
that will be obtained.

    Attached hereto and collectively marked Exhibit "E" are income statements 
for the Debtors' operating entities, AVRE and Binary, for the year ending 
1994 and for the nine (9) months ending September 30, 1995.  These income 
statements have been prepared by the Debtors and are unaudited.  Since ABI 
discontinued its operations prior to the Chapter 11 filing, no historical 
financial information is provided.  The income statements for "SeraCare" 
reflect the combined operation of AVRE and Binary.

    The Debtors believe that its business operations have sufficiently 
changed over the past two years that reliance upon historical financial data 
to project future operations is misleading.  For example, commencing January  
1, 1996, the Debtors have entered into a new contract with Alpha Therapeutic 
which provides for a $2.00 per unit higher pricing than the previous contract 
with Octafarma. In addition, 1994 was a transition year wherein the Debtors: 
(1) obtained QPP certification for all six plasma centers, (2) cancelled 
subpar contracts with existing customers at non-QPP  pricing, (3) negotiated 
new contracts for QPP production with Alpha Therapeutics and Octafarma, (4) 
initiated advertising programs at all centers to increase donors, (5) 
replaced 4 of the 6 center managers and substantially upgraded the other 
personnel through newly established training programs, (6) initiated the CMV 
hyperimmune program which generates an $8.00 premium over standard source 
plasma, and (7) initiated the tetanus hyperimmune program.

    Attached hereto and marked Exhibit "F" is a chart showing the proposed
equity ownership of Reorganized ABI.

                                       XI.

                    COMPARISON OF THE DEBTORS' PLAN TO ALTERNATIVES

     In chapter 11 proceedings such as these, there are usually only three plan
scenarios.  First, there is a scenario under which substantially all of the
assets of the debtor are sold as a going concern.  This type of sale usually
preserves going concern values and provides to creditors an enhanced
distribution over that which they would receive in a piece meal liquidation. 
The second scenario involves liquidation of a debtor's assets either by the
debtor or by professionals such as an auctioneer.  In light of the presence of
secured debt, as in the present case, and because of the failure to

                                       -18-


                              EXHIBIT B  PAGE 110

<PAGE>

exploit going concern values, this process usually results in the smallest 
distribution to creditors.  The third scenario involves a reorganization 
based upon a debtor's continuing operations.  That is the type of plan that
the Debtors are proposing herein.

    The Debtors do not believe that a liquidation of their assets would be in 
the best interest of Creditors.  By virtue of the existence of a large 
Secured Claim and the forefeiture of going concern values, there would be no 
distribution to Unsecured Creditors in a liquidation (SEE liquidation 
analysis, INFRA, Article XIII).

    With regard to the second scenario, i.e., the sale of the Debtors' business
as a going concern, the Debtors have not received any offers for the purchase of
the entire business better than the Plan proposal, nor are they aware of any
interest in such an acquisition by any third parties.

    The Debtors have thus proposed a Plan which is based upon the continued 
operation of the business by the Debtors.  The Debtors have already divested 
themselves of the unprofitable whole blood collection business and are now 
engaged solely in the operation of plasma collection centers, which have 
historically generated a profit.

    The Debtors believe that the Reorganized Debtors will have the capability 
of generating sufficient earnings to satisfy the obligations in connection 
with the Plan.  Under the Debtors' Plan , Unsecured Creditors will receive 
cash payment totaling approximately 10% of the Allowed amount of their 
Claims, a cash distribution on the Effective Date of $200,000.  In addition, 
Unsecured Creditors shall received 10,000 shares of common stock of 
Reorganized ABI for pro rata distribution.  Holders of Unsecured Notes will 
receive 105,275 shares of common stock in Reorganized ABI.

    The foregoing demonstrated that the total "package" to Creditors under 
the proposed Plan is far more valuable than the distribution which Unsecured 
Creditors would receive in a liquidation.  Accordingly, the consideration 
being given to Creditors under the Plan is far more valuable than the 
distribution they could expect to receive in a liquidation.

                                 RISK FACTORS


              The Debtors' abilities to implement the Plan, to assure, 
           insofar as is possible, the feasibility of the Plan and to achieve 
           Confirmation of the Plan is subject to certain matters which 
           constitute important risk factors.  As yet, each of these matters 
           continues to be a risk.  Although the Debtors expect to resolve 
           successfully each of these matters, they cannot warrant that each, 
           or all, of these will be successfully resolved or how long 
           resolution of these matters will take.

     1.   FINANCIAL PROJECTIONS.

     The feasibility of the Plan and the Reorganized Debtors' ability to meet 
their obligations in the future are premised upon the Reorganized Debtors' 
performance after they emerge from Chapter 11.  The Reorganized Debtors' 
future performance is predicated in terms of financial projections which rest 
upon a number of overall economic assumptions and assumptions made by the 
Debtors about their future business and the markets in which they function.  
Such information is necessarily forward looking and is provided herein to 
demonstrate the feasibility of the Plan.  Although the Debtors believe that 
the projections and assumptions are reasonable, no assurance can be given 
that they are correct.  In particular, it should be understood that the 
Debtors face severe competition in all the markets in which they compete.  
Furthermore, unanticipated events and circumstances such as economic 
recession may affect the actual financial results.

     2.   NATIONAL RESTRICTIONS ON THE IMPORT OF PLASMA.

     A significant portion of plasma collected in the United States (around 
40%) is exported to Europe where it is fractionated.  Recent events in 
Germany have provided motivation for the government to declare its intention 
to make Germany independent of foreign source plasma.  It is estimated that 
Germany currently imports around 1 million liters from the U.S. annually.  
Observers of the industry believe, however, that despite the rhetoric, there 
is no practical plan being considered within Germany which would allow this 
goal to be achieved or even seriously attempted.  To further ensure the 
continuation of the German market for U.S. plasma, the U.S. plasma industry 
has been adopting voluntary quality standards (QPP standards) which would 
further minimize any legitimate German concern over the quality of U.S. 
source plasma.  

     3.   DEVELOPMENT OF RECOMBINANT PRODUCTS.

     Significant amounts of plasma are used in the production of Factor VIII. 
Recently, a genetically engineered Factor VIII has been approved by the FDA 
and is available in the market.  The advantage of this recombinant product is 
an increased margin of safety from contamination by Hepatitis or HIV.  On the 
other hand, recombinant Factor VIII will sell for approximately three times 
the price of plasma derived from Factor VIII.  While patients have been able 
to get reimbursement for the new Factor VIII, many are finding that they are 
reaching the lifetime limits of their policies at an unacceptably high rate.

     Offsetting revenues which will be lost due to recombinant Factor VIII is 
the significant increase in the use of plasma in the manufacture of IV immune 
globulins.

     While research is continuing on genetically engineered substances, it is 
unlikely that other recombinant substitutes for plasma derived products will 
be available for at least ten years.

                CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE PLAN

     Under the Internal Revenue Code of 1986 (the "Internal Revenue Code"), 
there are significant federal income tax consequences associated with the 
Plan described in this Disclosure Statement.  However, it is not practicable 
to present a detailed explanation of all of the federal income tax aspects of 
the Plan and the following is only a summary discussion of certain of the 
significant consequences.

     The tax consequences of the implementation of the Plan to a creditor 
receiving ABI securities will depend in part on whether that Creditor's 
present debt Claim constitutes a "security" for federal income tax purposes.  
The determination as to whether the Claim of any particular Creditor 
constitutes a "security" for federal income tax purposes is complex, and 
depends on the facts and circumstances surrounding the origin and nature of 
the Claim.  Generally, Claims arising out of the extension of trade credit 
have been held not to be securities, while corporate debt obligations 
evidenced by written instruments with maturities when issued, of 10 years or 
more, have generally been held to be securities.  The Debtors express no 
views with respect to whether the Claim of any particular Creditor 
constitutes a "security" for federal income tax purposes and urges each 
Creditor to consult its tax advisor.

     A Creditor which exchanges its existing Claim for securities of ABI may 
recognize income or loss with regard to consideration received in respect of 
accrued interest attributable to its existing Claim, and gain or loss on the 
exchange of the principal of the Claim for securities.

     Under present law, there is substantial uncertainty surrounding many of 
the tax consequences.  Uncertainty is created, in part, by the changes made 
by the Bankruptcy Tax Act of 1980, the Tax Reform Act of 1984, the Tax Reform 
Act of 1986 and the Revenue Reconciliation Act of 1990, certain provisions of 
which call for the promulgation of regulations by the Treasury Department 
which have not yet been promulgated in final form.  In addition, there are 
differences in the nature of the Claims of various Creditors, their methods 
of tax accounting and prior actions taken by Creditors with respect to their 
Claims.  Further, the federal income tax consequences to any particular 
Creditor may be affected by a variety of matters.  For example, certain types 
of Creditors (including non-resident aliens and tax exempt organizations) may 
be subject to special rules. The transactions contemplated herein may also 
have significant state and local tax consequences.  Neither a ruling from the 
Internal Revenue Service (the "IRS") nor an opinion of counsel has been 
requested with respect to the federal income tax consequences of the Plan.

     ACCORDINGLY, HOLDERS OF CLAIMS AND INTEREST ARE URGED TO CONSULT THEIR 
TAX ADVISORS WITH SPECIFIC REFERENCE TO THE FEDERAL, STATE AND LOCAL TAX 
CONSEQUENCES OF THE PLAN WITH RESPECT TO THEIR CLAIM OR INTEREST.

           STATUS AND RESALE OF SECURITIES TO BE ISSUED PURSUANT TO PLAN

     Under Bankruptcy Code section 1145, the original issuance of the 
Reorganized Debtor's securities (hereinafter "Securities") under the Plan 
will be exempt from the registration on requirements of the Securities Act of 
1933 and applicable state laws requiring registration of securities.  Resale 
of Securities by a Creditor receiving them directly under the Plan will also 
be exempt provided the Creditor is not an underwriter.  Generally, a Creditor 
will not be deemed to be an underwriter if it:  (1) has not become a Creditor 
of the Debtor with a view to distribution of any Securities to be received in 
exchange for claims under the Plan; (2) has not offered to sell the 
securities for others; (3) has not offered to buy the securities from others 
where that offer is with a view to their distribution, and under an agreement 
made in connection with the Plan; (4) is not an issuer as that term is used 
in the Securities Act of 1933.  The determination of whether a particular 
Creditor would be deemed to be an underwriter is necessarily an individual 
one, and any Creditor considering reselling Securities under the Plan should 
consult with its securities advisor to determine whether it would be an 
underwriter, and therefor, ineligible for the exemption described above.

     A Creditor who is deemed to be an underwriter may be able to sell 
Securities without registration pursuant to the provisions of Rule 144 under 
the Securities Act of 1933, which fact may permit the public sale of 
Securities received pursuant to the Plan by underwriters subject to volume 
limitations and certain other conditions.  Creditors who believe they may be 
underwriters are advised to consult their own counsel with respect to the 
availability of the exemptions provided by Rule 144.

     THE ABOVE DISCUSSION IS INTENDED AS GENERAL INFORMATION ONLY, AND ANY 
ENTITY DESIRING TO RESELL ANY SECURITIES RECEIVED BY IT PURSUANT TO THE PLAN 
IS URGED TO CONSULT ITS SECURITIES ADVISOR REGARDING THE AVAILABILITY OF ANY 
REGISTRATION EXEMPTION.

                                    XVI.

                         ACCEPTANCE AND CONFIRMATION

A.   ACCEPTANCE.

     As a condition to Confirmation, the Bankruptcy Code requires that each 
impaired class of claims or interests accepts the Plan, with the exceptions 
described in the following section.  The Bankruptcy Code defines acceptance 
of a plan by a class of claims as acceptance by holders of two-thirds in 
dollar amount and a majority in number of claims of that class, but for this 
purpose counts only those who actually vote to accept or to reject the plan.  
The Bankruptcy Code defines acceptance of a plan by a class of interests 
(equity securities) as acceptance by two-third of the number of shares, but for
this purpose counts only shares actually

                                       -25-


                              EXHIBIT B  PAGE 117

<PAGE>

two-thirds voted.  Holders of claims or interests who fail to vote are not 
counted as either accepting or rejecting the Plan.

     Classes of claims and interest that are not "impaired" under a plan are 
deemed to have accepted the plan.  Acceptances of the Plan are being 
solicited only from those persons who hold claims or interests in impaired 
classes.  A class is "impaired" if the legal, equitable, or contractual 
rights attaching to the classes or interests of that class are modified, 
other than by curing defaults and reinstating maturities or by payment in 
full in cash.  Classes 2, 3, 4, 5 and 6 Claims and Class 7 Interests are 
impaired under the Plan.

B.   CONFIRMATION WITHOUT ACCEPTANCE BY ALL IMPAIRED CLASSES.

     The Bankruptcy Code contains provisions for confirmation of a plan even 
if the plan is not accepted by all impaired classes, provided at least one 
impaired class of claims has accepted it.  These "cramdown" provisions for 
confirmation of a plan despite the nonacceptance of one or more impaired 
classes of claims or interests are set forth in Section 1129(b) of the 
Bankruptcy Code.

     If a class of unsecured claims rejects the Plan, it may still be 
confirmed so long as the Plan provides that (i) each holder of a claim 
included in the rejecting class receives or retains on account of that claim 
property which has a value, as of the Effective Date, equal to the allowed 
amount of such claim; or that (ii) the holder of any claim or interest that 
is junior to the claims of such class will not receive or retain on account of 
such junior claim or interest any property at all.  The Debtors believe that 
the Plan does meet this test with regard to ABI and therefore the Plan may be 
confirmed if it is rejected by Class 3 or 4 claimants.  With regard to AVRE 
and Binary, the Debtors believe that the Plan does not meet this test and 
therefore the Plan cannot be confirmed if it is rejected by Class 5 or Class 
6 claimants.

     If a class of equity security interest rejects the Plan, the Plan may 
still be confirmed so long as the plan provides that (i) each holder of an 
interest included in the rejecting class receives or retains on account of 
that claim property which has a value, as of the Effective date, equal to the 
greatest of the allowed amount of any fixed liquidation preference to which 
such holder is entitled, any fixed redemption price to which such holder is 
entitled, and the value of such interest; (ii) the holder of any interest 
that is junior to the interests of such class will not receive or retain 
under the plan on account of such junior interest any property at all.  The 
Debtors believe that the plan meet this test with respect to Classes 7 and 8 
Interests, and, therefore, the Plan can be confirmed even if it is rejected 
by the holders of Classes 7 and 8 Interests.

                                      CONCLUSION

     The Bankruptcy Court, after notice and hearing, approved this Disclosure 
Statement as containing information adequate to permit holders of Allowed 
Claims and Allowed Interests that are impaired under the Plan to make an 
informed judgment as to whether or not to accept the Plan.  The Debtors 
believe that the Plan is feasible and in the best interests of all persons 
holding Allowed Claims and Allowed Interests, and recommend acceptance of the 
Plan.

payment of approximately 10% of the allowed amount of its Claim, a pro rata 
distribution of 10,000 shares of Reorganized ABI's common stock and fifty 
percent of any net affirmative recovery received by the Debtors against 
recipients of avoidable transfers.  Holders of Unsecured Notes will receive 
securities in Reorganized ABI.  Equity interests in ABI are wiped out.  
General unsecured creditors of AVRE and Binary will be paid in cash 80% of 
their claims as soon as practicable after the Effective Date.

Interests in the Debtors.

     SECTION 4.2  CLASS 1 - PRIORITY CLAIMS.  Each Holder of a Class 1 Claim

Claim on the Effective Date, unless such Holder shall have agreed to a

first payment to CVD under the promissory note shall commence on the first 
day of the month, one full month after the Effective Date.

the Reorganized Debtors will continue making payments of interest and 
principal based upon a promissory note with a face amount of not more than 
$1,000,000 until the Bankruptcy Court renders a decision on the challenge to

                                  ARTICLE VIII

                            EFFECT OF CONFIRMATION

     SECTION 8.1  DISCHARGE.  Except as otherwise provided in this 
Reorganization Plan or in the Confirmation Order, Confirmation shall operate 
as a discharge pursuant to Bankruptcy Code Section 1141(d)(1), of any and all 
debts or Claims against each Debtor that arose at any time before 
Confirmation, including but not limited to all principal and interest, 
whether accrued before, on or after the filing date.  The discharge shall 
become effective after the Effective Date and when the initial distribution 
to creditors holding uncontested Claims of the cash and securities has been 
made.  The Debtors will apply for an order of discharge upon providing a 
declaration to the Court setting forth that such initial distribution has 
been made.  As to every discharged debt and Claim, the creditor that held 
such debt or Claim shall be precluded from asserting against any Debtor 
herein or against a Debtor's assets or a Reorganized Debtor or any assets of 
a Reorganized Debtor, any or further Claim based upon any document, 
instrument or act, omission, transaction or any other activity of any kind or 
nature that occurred prior to the Confirmation Date, including, without 
limitation, Claims in the nature of successor liability.  Without limiting 
the generality of the foregoing, on the Effective Date the Debtor shall be 
discharged from any debt that arose before the date of Confirmation and any 
debt of the kind specified in Sections 502(g), 502(h) or 502(i) of the 
Bankruptcy Code to the full extent permitted by Section 1141 (d)(1)(A) of the 
Bankruptcy Code.  Furthermore, all Claims and debts against each Debtor which 
are so discharged may not be asserted against any Reorganized Debtor under 
any circumstances unless pursuant to the provisions of the Reorganization 
Plan.

     The Order of Confirmation shall operate as an injunction against the 
commencement or continuation of any act relating to the collection or 
enforcement of any Claim governed by the discharge provisions hereof.

existence at any time before these cases were filed.  Any Claims arising out 
of the rejection of executory contracts or leases under Article IX must be 
filed with the Court within thirty (30) days after Confirmation or be forever 
barred.  A separate notice will be sent by the Debtors upon Confirmation to 
the holders of contracts to be rejected advising them of this deadline for 
filing Claims.

     The failure of the Reorganized Debtors to make timely payment of any of 
their monetary obligations or to timely perform any of their non-monetary 
obligations under and pursuant to the terms and conditions herein set forth 
shall constitute an event of default.  The Committee or any party in interest

pursue any remedy provided for herein or pursuant to any other applicable law 
which remedies shall include, but shall not necessarily be limited to the 
following:

          a.   The Committee or any party in interest may declare a default

law in support thereof.  Following the entry of such an order and the same 
becoming a final order, any party affected thereby may initiate an action in 
any court of competent jurisdiction to recover the balance due to such party.

          b.   The Committee or any party in interest may seek to convert the 
case to one under Chapter 7 of the Bankruptcy Code or seek the entry of an 
order dismissing the case pursuant to the provisions of 11 U.S.C. Section 
1112(b).

Mr. Alfred Jay Moran, Jr.
American Blood Institute, Inc.
A.K.A. SeraCare
1875 Century Park East
Suite 2130
Los Angeles, CA  90067


Dear Mr. Moran:

First Equity Capital Securities, Inc. ("First Equity") is interested in and 
intends to procure financing for American Blood Institute, Inc. A.K.A. 
SeraCare (the "Company"). First Equity agrees to raise, on behalf of the 
Company proceeds to purchase 10% Promissory Note ("Debtor Certificates") in a 
net amount of at least $1,175,000.  The holders of the Debtor Certificates 
shall receive 76.1% of the common stock of the Company.

     Private Placement

The Company will appoint First Equity as the exclusive Selling Agent 
assisting in the selling of the Debtor Certificates in connection with this 
private placement.  The private placement will take place on a "best efforts" 
basis.

No funds shall leave escrow without the written approval of First Equity.  
The closing of this offering shall be contingent upon approval by the 
Bankruptcy Court of the plan to be submitted by the debtor in possession 
(such plan to be approved by First Equity) and upon the successful emergence 
of the Company from Bankruptcy.

The terms and conditions of this private placement shall be as set forth on 
the Term Sheet attached hereto.

     Compensation due on Emergence/Closing

The Company shall be obligated to pay First Equity the compensation as set 
forth on the Term Sheet only upon (i) the closing of the offering and (ii) 
successful emergence of the Company from bankruptcy.

     Expenses

Upon closing and emergence, the Company will bear all reasonable costs and 
expenses incident to the issuance, offer, sales and delivery of the units, 
including reasonable legal expenses of First Equity's counsel and any other 
reasonable expenses incurring by First Equity in connection with this private 
placement.

                              EXHIBIT B  PAGE 143

<PAGE>

     Bridge Loan

First Equity shall procure for the Company a bridge loan in the amount of not 
less than $50,000 or more than $50,000 on or before November 3, 1995 (unless 
such date is extended by the Company).  Such funds shall be used to pay 
expenses of the Company related to this offering and the bankruptcy.  The 
bridge lender(s) shall receive the right to convert such bridge loan interests
into the private placement on favorable terms.  Such premium shall not 
increase the gross amount of shares to be issued to the investors.

     Intention to be a Public Company

First Equity and the Company each acknowledge that it is the intention of all 
parties that the Common Stock of the Company be free trading and that the 
Company be a publicly traded company as soon as possible, although the 
Company intends that it be public and that its common stock will be freely 
tradable concurrent with its emergence from bankruptcy, all parties agree 
that the issuance of additional shares may be necessary in order to achieve 
this end (i.e., 300 shareholders).  Both parties also acknowledge that, if 
this scenario is not achievable or if the parties otherwise desire, a 
reverse merger into a public shell may be necessary. Under these of
other scenarios, all parties acknowledge that additional shares (above
2,000,000) may be issued and that all parties shall be diluted thereby. 

     Indemnification

First Equity and the Company will each agree to indemnify and hold harmless 
the other against any and all claims, etc., with respect to any information 
provided by the indemnifying party for inclusion in any private placement 
memorandum or offering circular.

Very truly yours,
FIRST EQUITY CAPTIAL SECURITIES, INC.

SeraCare
Term Sheet for Financing and Plan of Reorganization

This Term Sheet assumes a gross raise of $1,175,000.00 of which $50,000.00 
will be deposited with SeraCare on or before November 3, 1995.  The balance 
of $1,125,000 will be deposited into escrow on or before December 30, 1995 
and will be used to purchase Debtor Certificates on or about the effective 
date of the Plan of Reorganization.

Use of Funds is anticipated as follows:
     General Unsecured Creditors                             $  200,000
     Downpayment to Secured Creditors                           600,000
     Administrative costs (mainly legal)                        195,000
     Investment Banker Fees - First Equity Capital (1)           90,000
     Investment Banker Fees - Anthony Bryant (1)                 60,000
     Investment Banker Fees - Sundlund Capital (1)               30,000
                                                            -------------
                                                             $1,175,000
                                                            -------------
                                                            -------------

(1) All Investment Banker fees are contingent upon the emergence from 
    bankruptcy.

The Debtor Certificates representing the $1,175,000.00 shall convert into 
1,610,708 shares of SeraCare on emergence.  SeraCare contemplates utilizing 
warrants or a secondary offering to provide for the secondary financing 
necessary for the purchase of additional centers.

Management will receive 189,495 shares of common stock of SeraCare plus 
options to purchase 126,330 shares of common stock of SeraCare at a 
calculated price which is the mean average between $.74 per share and the 
weighted average of the closing bid price for the company's stock for the 
thirty trading days prior to the vesting date.  The vesting date is defined 
as the anniversary date of the effective date of the Reorganization Plan as 
herein defined.  The options will vest at the rate of one-third per year and 
are contingent upon the company achieving the projected operating results 
reflected in the Confidential Memorandum except that if the indicated funding 
is not provided in timely fashion for acquisition of the indicated centers 
reflected  in that Confidential Memorandum then a calculation will be made 
utilizing the projected results of the base six centers (which includes 
corporate overhead) plus a pro rated calculation of the projected operating 
results of the acquisition centers based upon the percentage of the secondary 
acquisition financing actually received by SeraCare.  For example, the 
projections contemplate the acquisition of twelve centers during the first 
year after emergence.  Accordingly, at the rate of $200,000 per center this 
acquisition program would require $2,400,000.  If $1,200,000 or 50% is 
actually funded, then a calculation will be made utilizing 100% of the First 
Year projected operating results which include corporate overhead ($365,556) 
plus 50% of the First Year projected operating results from the acquisition 
centers (50% X $450,198 = $225,009) with the summation of the two being 
($365,556 + 225,099 = $590,655).  Accordingly, $590,655 will be the objective 
criteria for vesting of one third of the options

if $1,200,000 of secondary financing is actually funded in Year One.  If 
SeraCare is sold, merged, or consolidated with another company, at which time 
the options will become immediately vested and exercisable.

Anthony Bryant will receive 78,956 shares of common stock of SeraCare.

First Equity will receive 94,748 shares of common stock of SeraCare.

Sundlund Capital will receive 26,319 shares of common stock of SeraCare.

The Unsecured Note Holders shall receive 105,275 shares of SeraCare.
Agreed Upon Plan of Reorganization:

     Class I -      Certain administrative claimants will be paid in cash:

                    Mainly Bankruptcy Counsel                  $195,000
                    
                    The invested funds of $1,175,000 will purchase Debtor 
                    Certificates which will convert into 1,610,708 shares 
                    of common stock of SeraCare on the effective date.
               
     Class II -     The tax claims of about $5,000 will paid in cash.
     
     Class III -    The Secured claim of CVD Financial estimated to be 
                    $1,600,000 will be paid in full ($600,000 upon

     Class IV -     Unsecured Note Holders totaling approximately $440,000

     5.   PERFORMANCE BONUS. There shall also be a Management Bonus Pool 
which will allocate ten percent (10%) of pre-tax earnings which are in excess 
of $920,549 in year one following the Effective Date of the Reorganization 
Plan, $2,590,160 in year two, $4,384,187 in year three, $6,244,536 in year 
four, and $8,166,626 in year five to a bonus pool to be paid pro rata to 
management on the basis of salaries.  Moran shall be a participant in this

and as may be provided in the ordinary course to the Corporation's other 
senior executives.

     7.   STOCK AND WARRANT GRANT.  Moran shall be granted 84,220 shares of 
common stock of SeraCare (SeraCare is herein defined as AVRE, Inc., Binary 
Associates, Inc., American Blood Institute, Inc. and any post emergence 
replacement or successor corporation or entity into which the Plasma 
Operations of Avre, Inc. and Binary Associates, Inc. are transferred, placed, 
controlled, merged or which are acquired by) and stock options to purchase 
56,147 shares of common stock in SeraCare for a calculated price which is the 
mean average between $.74 and the weighted average of the closing bid price 
for the Company's stock for the thirty trading days prior to the vesting 
date.  The vesting date is defined as the anniversary date of the Effective 
date of the Reorganization Plan for SeraCare.  The options will vest at the 
rate of one-third per year and are contingent upon the company achieving the 
projected operating results reflected in the Confidential Memorandum attached 
herewith except that if the indicated funding is not provided in timely 
fashion for the acquisition of the indicated centers reflected in the 
Confidential Memorandum, then a calculation will be made utilizing the 
projected results of the base six centers (which includes corporate overhead) 
plus a pro rated calculation of the projected operating results of the 
acquisition centers based upon the percentage of the secondary financing 
actually received by SeraCare.  For example, the projections contemplate the 
acquisition of twelve centers during year one.  Accordingly, at the rate of 
$200,000 per center this acquisition program would require $2,400,000.  If 
$1,200,000 or 50% is actually funded, then a calculation will be made 
utilizing 100% of the year one operating results projected for the base six 
centers ($365,099) plus 50% of the year one projected operating results for 
the acquisition centers (50% X $450,198 = $225,099) with the summation of two 
being ($365,556 + $225,198 = $590,655).  Accordingly, $590,655 will be the 
objective criteria for vesting of one third of the options if $1,200,000 of 
secondary financing is actually received by SeraCare in year one.  If 
SeraCare is sold, merged, consolidated with another company or reorganized to 
the extent that there is a 50% or more change in ownership, the options will 
become immediately vested and exercisable.

     8.   TERM.  This Agreement is condition upon confirmation of the Plan of 
Reorganization for American Blood Institute, Inc., AVRE, Inc. and Binary 
Associates, Inc. and approval by the Federal Bankruptcy Court.  The term 
shall be for the three year period beginning on the "Effective Date" of the 
Confirmed Plan of Reorganization and ending thirty six months after the 
"Effective Date" unless this Agreement is terminated at an earlier date as 
provided in Section 9 below.

and as may be provided in the ordinary course to the Corporation's other 
senior executives.

     7.   STOCK AND WARRANT GRANT.  Olson shall be granted 42,110 shares of 
common stock of SeraCare (SeraCare is herein defined as AVRE, Inc., Binary 
Associates, Inc., American Blood Institute, Inc. and any post emergence 
replacement or successor corporation or entity into which the Plasma 
Operations of Avre, Inc. and Binary Associates, Inc. are transferred, placed, 
controlled, merged or which are acquired by) and stock options to purchase 
28,073 shares of common stock in SeraCare for a calculated price which is the 
mean average between $.74 and the weighted average of the closing bid price 
for the Company's stock for the thirty trading days prior to the vesting 
date.  The vesting date is defined as the anniversary date of the Effective 
date of the Reorganization Plan for SeraCare.  The options will vest at the 
rate of one-third per year and are contingent upon the company achieving the 
projected operating results reflected in the Confidential Memorandum attached 
herewith except that if the indicated funding is not provided in timely 
fashion for the acquisition of the indicated centers reflected in the 
Confidential Memorandum, then a calculation will be made utilizing the 
projected results of the base six centers (which includes corporate overhead) 
plus a pro rated calculation of the projected operating results of the 
acquisition centers based upon the percentage of the secondary financing 
actually received by SeraCare.  For example, the projections contemplate the 
acquisition of twelve centers during year one.  Accordingly, at the rate of 
$200,000 per center this acquisition program would require $2,400,000.  If 
$1,200,000 or 50% is actually funded, then a calculation will be made 
utilizing 100% of the year one operating results projected for the base six 
centers ($365,556) plus 50% of the year one projected operating results for 
the acquisition centers (50% X $450,198 = $225,099) with the summation of two 
being ($365,556 + $225,198 = $590,655).  Accordingly, $590,655 will be the 
objective criteria for vesting of one third of the options if $1,200,000 of 
secondary financing is actually received by SeraCare in year one.  If 
SeraCare is sold, merged, consolidated with another company or reorganized to 
the extent that there is a 50% or more change in ownership, the options will 
become immediately vested and exercisable.

     8.   TERM.  This Agreement is condition upon confirmation of the Plan of 
Reorganization for American Blood Institute, Inc., AVRE, Inc. and Binary 
Associates, Inc. and approval by the Federal Bankruptcy Court.  The term 
shall be for the three year period beginning on the "Effective Date" of the 
Confirmed Plan of Reorganization and ending thirty six month after the 
"Effective Date" unless this Agreement is terminated at an earlier date as 
provided in Section 9 below.

Agreement, the successful or prevailing party shall be entitled to recover 
reasonable attorney's fees incurred after a judgement has been rendered by a

                              SeraCare
             Assumptions Underlying Four Year Forecast

The  attached financial forecasts were prepared by management  of SeraCare 
and are based upon assumptions which management believes are  reasonable.  
Nevertheless, the attached financial  forecasts are  based  upon  assumptions 
which may or may not  prove  to  be accurate or appropriate.  No assurances 
can be given that any  of the  results or events described herein will occur, 
or  that  if they  do  occur, they will occur at the predicted times.   
Actual results may vary widely from projected results.  Accordingly, the 
financial  forecasts should not be replied upon to  indicate  the actual  
results  which will be attained by  SeraCare  during  the forecasted periods.

The  four years forecasted herein have been predicated on meeting the  
Company's  strategic objective of  expanding   the  business through  the  
internally generated cash flow.  To this  end,  the forecast  illustrates  
how  additional  plasma  centers  can   be acquired  during  the  four  year  
period.   While  there  is  no particular reason why such acquisitions can not 
be made, there can be  no guarantees that they will be made or that the 
results will be presented herein.

Other assumptions areas follows:

1.   The  assumed  rate  of  acquisition  is  reflected  on  the projected
     Statements of Income attached herewith.

2.   The  attached forecasts assume that production from acquired
     centers  will  be  sold  domestically at approximately  the  same
     prices as currently being received.


                              EXHIBIT D  PAGE 72


                              EXHIBIT B  PAGE 168

<PAGE>




3.   It is expected that by January 1996, 25% of the plasma
     collected (approximately 25,000 annually) will be hyperimmune
     and will yield a $3.00 to $8.00 premium per liter over source
     plasma.

4.   The  cost of acquired centers is assumed  to be $200,000 each
     with fixed assets of $90,000, goodwill of $60,000, and net
     current assets of $50,000. It has been assumed that all
     acquisitions will be made for cash with no financing.

5.   Goodwill has been amortized over 17 years consistent with the
     AICPA pronouncement .

6.   After considering the impact of the "1986 tax act", taxes
     have been calculated based upon the assumption that the current
     loss carry-forward of approximately $6.5 million will be
     available to SeraCare at the rate of $150,000 per year for 15
     years.  Under the provisions of the 1986 tax act, such an
     assumption may or may not be valid depending upon the ultimate
     determination of ownership, control and business activity.

7.   The basic framework of this presentation is that a net of 
     $.995 million is received by SeraCare and used as follows:

           To pay down secured lender         $600,000
           To pay Unsecured Creditors          200,000
           Administrative legal fees           195,000
                                              --------
                                              $995,000
                                              --------
                                              --------

8.   In preparation of the four year forecast for SeraCare, the
     following Monthly Acquisition Model was used to reflect the
     impact of acquisitions:

     Revenue(1)                   63,000

           liters per week.

     (2)   Staffing includes: one manager @$2,500; one nurse @$2,500;
           10 technicians/receptionists/phlebotomists  @$8,000; and one

<PAGE>

Robinson, Diamant, Brill & Klausner, A Professional Corporation by Martin J.
Brill.  Other appearances were made as reflected on the record.

          Based upon the pleadings and records on file in this case, the
amendments to the Joint Plan, the settlement with CVD Financial Corporation
("CVD") previously approved by the Court, the arguments of counsel and other
evidence presented at the hearing, the Court finds as follows:

          1.   Notice of the confirmation hearing was appropriate under
Bankruptcy Code section 102, Federal Rule of Bankruptcy Procedure 2002, and the
order approving the Disclosure Statement regarding the Joint Plan;

          2.   This matter is a core proceeding under 28 U.S.C. Section 157;

          3.   The Joint Plan was filed on November 27, 1995, and copies of 
the Joint Plan, Disclosure Statement, notice of hearing to consider 
confirmation, and ballots were transmitted to all creditors, equity security 
holders of the Debtors and other parties in interest on December 8, 1995 in 
accordance with the Order approving the Disclosure Statement;

          4.   The Joint Plan was modified by Amendment to Third Amended Joint
Plan of Reorganization of American Blood Institute, Inc., AVRE, Inc., and Binary
Associates, Inc. filed on January 3, 1996 (the "First Amendment");

          5.   The Joint Plan was further modified by Second Amendment to Third
Amended Joint Plan of Reorganization of American Blood Institute, Inc., AVRE,
Inc., and Binary
          
                                   -2-
          
<PAGE>

Associates, Inc. filed on January 19, 1996 (the "Second Amendment");

           6.   The Debtors have solicited consents to the Joint Plan consistent
with Bankruptcy Code section 1125, Federal Rule of Bankruptcy Procedure 2002 and
this Court's order approving the Disclosure Statement regarding the Joint Plan;

           7.   The Joint Plan complies with all the requirements of Bankruptcy
Code section 1129;

           8.   The Debtors have complied with all of the provisions of Title 11
of the United States Code;

           9.   The Joint Plan complies with all of the provisions of Title 11
of the United States Code;

           10.  The Joint Plan has been proposed by the Debtors in good faith
and not by any means forbidden by law;

           11.  The Joint Plan has been accepted in writing by all creditors and
equity security holders whose acceptances are required by law;

           12.  At least one class of claims that is impaired under the Joint
Plan has accepted the Joint Plan, determined without including any acceptance of
the Joint Plan by any insider;

           13.  Each holder of a Claim or Interest has accepted the Joint Plan
or will receive or retain under the Joint Plan property of a value, as of the
Effective Date of the Joint Plan, that is not less than the amount that such
holder would receive or retain if the Debtors' assets were liquidated under
chapter 7 of the Bankruptcy Code on that date;

                                   -3-
<PAGE>

           14.  The Joint Plan does not discriminate unfairly and is fair and
equitable with respect to each class of Claims or Interests that is impaired
under the Joint Plan;

           15.  All payments made or promised by the Debtors for services or
costs and expenses in, or in connection with the Joint Plan and incident to this
chapter 11 case, have been fully disclosed to the Court and are reasonable, or,
if to be fixed after confirmation of the Joint Plan will be subject to the
approval of the Court;

           16.  The identities, qualifications, and affiliations of the persons
who are to be directors or officers of the Debtors after the Effective Date have
been fully disclosed, and the appointment of such persons to such offices, or
their continuance therein, is equitable and consistent with the interest of
creditors and equity security holders and with public policies;

           17.  Confirmation of the Joint Plan is not likely to be followed by
any liquidation, or the need for further financial reorganization, of the
Debtors; and

           18.  The Joint Plan complies with the requirements of Bankruptcy Code
section 1123.

           NOW, THEREFORE, for the foregoing reasons and good cause, it is
hereby

           ORDERED that:

           A.   The Joint Plan as modified by the First Amendment and the Second
Amendment is hereby confirmed pursuant to Bankruptcy Code section 1129(a);
           
                                   -4-
<PAGE>

          B.   The Debtors are authorized to take all steps and to enter into
any transaction reasonably necessary to implement the Joint Plan;

          C.   In accordance with Bankruptcy Code section 1141(a), the
provisions of the Joint Plan shall bind the Debtors, any entity acquiring
property under the Joint Plan, and any creditor or equity security holder,
whether or not the Claim or Interest of such creditor or equity security holder
is impaired under the Joint Plan and whether or not such creditor or equity
security holder has accepted the Joint Plan;

          D.   The Debtors may apply for a discharge in accordance with and to
the fullest extent allowed by Bankruptcy Code section 1141 once the initial
distribution of the cash and securities has been made to creditors holding
uncontested Claims;

          E.   Pursuant to Article IX of the Joint Plan, the Debtors assume the
following executory contracts:

               1.   Leases of real property for the following locations:

                    a.   611 North Las Vegas Boulevard, Las Vegas, Nevada;

                    b.   1174 Fort Campbell Boulevard, Clarksville, Tennessee;

                    c.   129 and 141 North Spruce, Colorado Springs, Colorado; 
and

                    d.   411 and 413 West 4th Street, Pueblo, Colorado.

               2.   Contracts for sale of source plasma with Alpha Therapeutics,

                                   -5-
<PAGE>

          F.   In accordance with Article IX of the Joint Plan, each 
executory contract or unexpired lease of the Debtors that is or was not 
assumed by order of the Bankruptcy Court and that is not assumed by the 
Debtors pursuant to Article IX of the Joint Plan, is rejected.  Within thirty 
(30) days following entry of this Order, the holder of any Claim arising from 
rejection of an executory contract or unexpired lease shall file with the 
Clerk and serve upon the Debtors and its counsel a proof of claim for damages 
resulting from rejection or be barred from asserting such Claim or receiving 
any dividend or payment on account of such Claim;

          G.   All applications for final compensation of professional persons
for services rendered and for reimbursement of expenses incurred on or before
the Effective Date (including, without limitation, any compensation requested by
any professional or other entity for making a substantial contribution to these
cases), and all other requests for payment of administrative costs and expenses
incurred before the Effective Date, shall be filed no later than 60 days after
the Effective Date unless otherwise extended by the Court.  Holders of
Administrative Claims who fail to timely file such requests shall be barred from
asserting such Claims against the Debtors;

          H.   The Court shall retain jurisdiction as provided in the Joint Plan
and in accordance with the Joint Plan and applicable law;

          I.   All securities of Reorganized ABI to be issued in accordance with
the Plan to creditors or equity interest holders will not be registered under
the Securities Act of 1933, as
          
                                   -6-
<PAGE>

amended, or under any state or local securities laws and will be issued under an
exemption from registration provided by section 1145 of the Bankruptcy Code (11
U.S.C. Section 1145);

          J.   The Reorganized Debtors are authorized to enter into the
employment agreements with Jerry L. Burdick and Brian Olson attached to the
Disclosure Statement as Exhibit "C", which agreements are approved and made
binding upon the Reorganized Debtors;

          R.   On the Effective Date, the rights afforded in the Joint Plan, and
the treatment of all Claims and Interests therein, shall be in exchange for, and
in complete satisfaction, discharge and release of all Claims, including without
limitation, all Administrative Claims, Secured Claims, Priority Tax Claims,
other Priority Claims and Unsecured Claims, including any interest accrued on
such Claims from and after the Petition Date, against the Debtors;

          L.   Except as to those Claims and Interests which are assumed,
preserved or treated under the Joint Plan, on the Effective Date, all persons
shall be permanently enjoined by Bankruptcy Code section 524 from asserting
against the Debtors, their successors or their assets or properties, any other
or future Claims, Administrative Claims, or Interests based upon any act or
omission, transaction, or other activity of any kind or nature that occurred
prior to the Confirmation Date;

          M.   Subject to paragraphs 1.11.10, 1.11.11 and 4.7(a), (c) and (d) of
the Amended and Restated Loan Agreement ("the Loan Agreement"), and analogous
provisions of the Security Agreement, both incorporated into the Joint Plan 
through the Second

<PAGE>

Amendment, and excepting the Vacant Parcels as defined in the Loan Agreement and
Security Agreement, this Order shall provide CVD with a valid and perfected
first priority security interest in all of the collateral defined in the Loan
Agreement and Security Agreement ("the Collateral"), including without
limitation all now owned or hereafter acquired Accounts, Chattel Paper,
Contracts, Equipment, Fixtures, General Intangibles, Goods, Instruments,
Inventory and Proceeds of each of the Reorganized Debtors as those terms are
used in the California Commercial Code and all of ABI's shares of stock in AVRE
and Binary;

          N.   This Order shall supersede the perfection requirements of any
state law such that CVD will have no obligation to record any documents with any
state or county office or take any other steps to perfect CVD's liens and
security interests in the Collateral;

          0.   Within 120 days of the entry of this Order, the Debtors shall

consummation of the confirmed Plan. The initial Report must be served on the

days thereafter and served on the same entities, unless otherwise ordered by the
Court; and
