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

     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 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.  Burdick 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 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 + $225,099 = $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 month after the "Effective Date"
unless this Agreement is terminated at an earlier date as provided in Section 9
below.

for believing that the actions or associations are or could be materially
detrimental to the Corporation.
