ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On July 31, 1998 Bio-Vascular, Inc., a Minnesota corporation
("Bio-Vascular") acquired Jer-Neen Manufacturing Co., Inc., a Minnesota
corporation ("Jer-Neen"). The acquisition was completed pursuant to an
Acquisition Agreement and Plan of Reorganization dated as of such date (the
"Acquisition Agreement") by and among Bio-Vascular, Jer-Neen and Jer-Neen
Acquisition, Inc., a Minnesota corporation and a wholly-owned subsidiary of
Bio-Vascular (the "Acquisition Subsidiary"), and George Nelson, Jr., Ronald
Breckner, James Pfau, Willard Sykes and Catherine Sykes as the shareholders of
Jer-Neen (the "Shareholders"). Under the terms of the Acquisition Agreement,
Jer-Neen merged with and into the Acquisition Subsidiary, with the separate
existence of Jer-Neen ceasing and the Acquisition Subsidiary surviving (the
"Merger").

     Pursuant to the terms of the Acquisition Agreement, all of the issued and
outstanding shares of common stock of Jer-Neen were converted into the right to
receive an aggregate of $1,750,000 in cash and an aggregate of 585,872 shares of
common stock, $.01 par value per share, of Bio-Vascular ("Bio-Vascular Common
Stock"), with all of such cash paid and shares issued at the closing of the
Merger. The total consideration paid by Bio-Vascular was determined pursuant to
arms' length negotiations and took into account various factors concerning the
business and prospects of Jer-Neen.

     The number of shares of Bio-Vascular Common Stock issued in connection with
the Merger was determined pursuant to a letter of intent among Bio-Vascular and
each of the Shareholders, dated May 28, 1998. The letter of intent provided for
the stock portion of the consideration to consist of a number of shares of
Bio-Vascular Common Stock having an aggregate value of $2,750,000, based on the
average closing price of a share of Bio-Vascular Common Stock reported by the
Nasdaq National Market for (i) the ten consecutive trading days prior to public
announcement of execution of the letter of intent and (ii) the ten consecutive
trading days ending July 27, 1998. The 585,872 shares of Bio-Vascular Common
Stock issued to the Shareholders represented approximately 6.5% of the issued
and outstanding shares of Bio-Vascular Common Stock immediately prior to
issuance and approximately 6.1% of the issued and outstanding shares of
Bio-Vascular Common Stock immediately following issuance. All of the shares of
Bio-Vascular Common Stock issued to the Shareholders in connection with the
Merger are "restricted stock," as defined in the rules promulgated under the
Securities Act of 1933, as amended (the "Securities Act"), but the Acquisition
Agreement provides that Bio-Vascular will use reasonable best efforts to
register the resale of such shares under the Securities Act. Under the
Acquisition Agreement, Bio-Vascular will bear all registration, filing and
listing fees, printing expenses, fees and disbursements of counsel and
accountants for Bio-Vascular and all blue sky fees incurred in connection with
registration of such shares of Bio-Vascular Common Stock.

     At the closing of the Merger Bio-Vascular also paid an additional $950,000
in cash allocated among the Shareholders in consideration of each Shareholder's
covenant under the Acquisition Agreement, for a period of ten years following
closing of the Merger, not to engage, directly or indirectly, in certain
activities competitive with the business conducted by Jer-Neen prior to the
Merger.

                                       2
<PAGE>
 
     The total cash portion of the consideration paid to the Shareholders for
their Jer-Neen stock and with respect to the non-competition covenants was paid
out of Bio-Vascular's existing cash at the time of the closing of the Merger.

     Jer-Neen is a value-added manufacturer of precision components such as
micro coils, wire forms and spring components used in implantable
defibrillation, interventional medicine and other surgical applications within
the medical device industry. Following the Merger, Bio-Vascular will continue
Jer-Neen's business through the Acquisition Subsidiary, which has been re-named
Jer-Neen Manufacturing Co., Inc.

     James F. Pfau will continue to manage Jer-Neen's business as the president
of the Acquisition Subsidiary pursuant to an Employment Agreement among Mr.
Pfau, Bio-Vascular and the Acquisition Subsidiary, dated July 31, 1998. The
Employment Agreement provides for an initial term of three (3) years. Under the
Employment Agreement Bio-Vascular will grant Mr. Pfau restricted shares of
Bio-Vascular Common Stock vesting over a period of four (4) years and options to
purchase Bio-Vascular Common Stock becoming exerciseable over a period of four
(4) years. Bio-Vascular and Mr. Pfau have also entered into a Change in Control
Agreement providing Mr. Pfau with certain benefits in the event of a change in
control of Bio-Vascular. Mr. Pfau's Employment Agreement and Change in Control
Agreement are filed as exhibits to this report and are incorporated herein by
reference. Following the Merger Mr. Pfau will also be appointed as a vice
president of Bio-Vascular.

     For accounting purposes, it is intended that the Merger will be treated as
a purchase.

     Additional information regarding the Merger is contained in the Acquisition
Agreement, which is an exhibit to this report and is incorporated herein by
reference.

5.16. EMPLOYEE BENEFIT PLANS.

         (a) Schedule 5.16 sets forth an accurate schedule of each "employee
benefit plan," as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), and all nonqualified deferred
compensation arrangements, whether formal or informal and whether legally
binding or not, covering any present or former director, officer or employee of
the Company under which the Company has any current or future obligation or
liability or under which any present or former director, officer or employee of
the Company, or such present or former director's, officer's or employee's
dependents or beneficiaries, has any current or future right to benefits (each
such plan and arrangement referred to hereinafter as a "Plan"). Except as set
forth in Schedule 5.16, the Company does not sponsor, maintain or contribute
currently, or at any time since November 1, 1994, to any plan, program, fund or
arrangement that constitutes an employee pension benefit plan. Each Plan may be
terminated by the Company, at any time without any liability, cost or expense,
other than costs and expenses that are customary in connection with the
termination of a Plan. For purposes of this Agreement, the term "employee
pension benefit plan" shall have the meaning given that term in Section 3(2) of
ERISA.

         (b) Each Plan listed in Schedule 5.16 is in compliance in all material
respects with the applicable provisions of ERISA, the Code, the Public Health
Service Act and any other applicable Law. Except as set forth in Schedule 5.16,
with respect to each Plan of the Company (other than a "multiemployer plan," as
defined in Section 4001(a)(3) of ERISA), all reports and other documents
required under ERISA or other applicable Law to be filed with any Governmental
Authority, the failure of which to file could reasonably be expected to result
in a liability to the Company, or required to be distributed to participants or
beneficiaries, have been duly and timely filed or distributed. True and complete
copies of all such reports and other documents with respect to the past three
years for each Plan have been provided to BVI. No "accumulated funding
deficiency" (as defined in Section 412(a) of the Code) with respect to any Plan
has been incurred (without regard to any waiver granted under Section 412 of the
Code), nor has any funding waiver from the Internal Revenue Service been
received or requested. Except as set forth in Schedule 5.16, each Plan that is
intended to be "qualified" within the meaning of Section 401(a) of the Code (a
"Qualified Plan") is, and has been during the period from its adoption to the
date hereof, so qualified, both as to form and operation and all necessary
approvals of Governmental Authorities, including a favorable determination as to
the qualification under the Code of each of such Qualified Plans and each
amendment thereto, have been timely obtained. Except as set forth in Schedule
5.16, all accrued contribution obligations of the Company with respect to any
Plan have either been fulfilled in their entirety or are fully reflected in the
Financial Statements.

         (c) No Plan has incurred or will incur, and the Company has not
incurred and will not incur with respect to any Plan, any liability for excise
tax or penalty due to the Internal Revenue Service. There have been no
terminations, partial terminations or discontinuances of contributions to any
Qualified Plan since November 1, 1994 without notice to and approval by the
Internal Revenue Service and payment of all obligations and liabilities
attributable to such Qualified Plan.

                                       14
<PAGE>
 
         (d) Except as set forth in Schedule 5.16, the Company has not made any
promises of retirement or other benefits to employees, except as set forth in
the Plans, and the Company neither maintains nor has established any Plan that
is a "welfare benefit plan" within the meaning of Section 3(1) of ERISA that
provides for retiree medical benefits or any other continuing benefits or
coverage for any participant or any beneficiary of a participant after such
participant's termination of employment, except as may be required by Part 6 of
Subtitle B of Title I of ERISA and Section 4980B of the Code and similar state
Law provisions, and at the expense of the participant or the beneficiary of the
participant. The Company neither maintains, has established nor has ever
participated in a multiple employer welfare benefit arrangement as described in
Section 3(40)(A) of ERISA. Except as set forth in Schedule 5.16, the Company has
no current or future obligation or liability with respect to a Plan pursuant to
the provisions of a collective bargaining agreement.

         (e) The Company has not incurred any material liability to the Pension
Benefit Guaranty Corporation in connection with any Plan. The assets of each
Plan that are subject to Title IV of ERISA are sufficient to provide the
benefits under such Plan, the payment of which the Pension Benefit Guaranty
Corporation would guarantee if such Plan were terminated, and such assets are
also sufficient to provide all other "benefits liabilities" (as defined in ERISA
Section 4001(a)(16)) due under such Plan upon termination.

         (f) No "reportable event" (as defined in Section 4043 of ERISA) has
occurred and is continuing with respect to any Plan subject to Title IV of
ERISA. There are no pending claims, lawsuits or actions (other than routine
claims for benefits in the ordinary course) asserted or instituted against, and
to the Knowledge of the Stockholders there are no threatened litigation or
claims against, the assets of any Plan or its related trust or against any
fiduciary of a Plan with respect to the operation of such Plan. There are no
investigations or audits of any Plan by any Governmental Authority currently
pending and there have been no such investigations or audits that have been
concluded that resulted in any liability to the Company that has not been fully
discharged. The Company has not participated in any voluntary compliance or
closing agreement programs established with respect to the form or operation of
a Plan.

         (g) The Company has not engaged in any prohibited transaction, within
the meaning of Section 406 of ERISA or Section 4975 of the Code, in connection
with any Plan for which exemption was not available. Except as set forth in
Schedule 5.16, the Company neither is, nor ever has been, a participant in or is
obligated to make any payment to a multiemployer plan. No person or entity that
was engaged by the Company as an independent contractor since November 1, 1994
reasonably can or will be characterized or deemed to be an employee of the
Company under applicable Laws for any purpose whatsoever, including, without
limitation, for purposes of federal, state and local income taxation, workers'
compensation and unemployment insurance and Plan eligibility.

         (h) The Company has no liability or obligation with respect to any plan
or program maintained by any ERISA Affiliate which would be a Plan if it were
maintained by the Company for its employees. For purposes of this subsection
(h), the term "ERISA Affiliate" means any 

                                       15
<PAGE>
 
corporation or trade or business under common control with the Company as
determined under Section 414(b), (c), (m) or (o) of the Code.

5.17. LITIGATION AND COMPLIANCE WITH LAW. Except as set forth in Schedule 5.17,
there are no claims, actions, suits or proceedings, pending or to the Knowledge
of the Stockholders, threatened against or affecting the Company, at law or in
equity, or before or by any Governmental Authority having jurisdiction over the
Company. Except to the extent set forth in Schedule 5.17, the Company has
conducted and is conducting its business in compliance with all Laws applicable
to the Company, its assets or the operation of its business, except where such
noncompliance would not have a material adverse effect upon the financial
condition, operations, results of operations or business of the Company.

5.18. TAXES. For purposes of this Agreement, the term "Taxes" shall mean all
taxes, charges, fees, levies or other assessments including, without limitation,
income, gross receipts, excise, property, sales, withholding, social security,
unemployment, occupation, use, service, service use, license, payroll,
franchise, transfer and recording taxes, fees and charges, imposed by the United
States or any state, local or foreign government or subdivision or agency
thereof, whether computed on a separate, consolidated, unitary, combined or any
other basis; and such term shall include any interest, fines, penalties or
additional amounts attributable to or imposed with respect to any such taxes,
charges, fees, levies or other assessments. The Company has timely filed all
requisite federal, state, local and other tax returns for all fiscal periods
ended on or before the Closing, and has duly paid in full or made adequate
provision in the Financial Statements for the payment of all Taxes for all
periods ending at or prior to the Balance Sheet Date and has duly paid in full
or made adequate provision in the books and records of the Company for the
payment of all Taxes for all periods commencing after the Balance Sheet Date and
ending at or prior to the Closing Date. The Company has duly withheld and paid
or remitted all Taxes required to have been withheld and paid in connection with
amounts paid or owing to any employee, independent contractor, creditor,
shareholder or other person or entity that required withholding under any
applicable Law, including, without limitation, any amounts required to be
withheld or collected with respect to social security, unemployment
compensation, sales or use taxes or workers' compensation. Except as set forth
in Schedule 5.18, the Company has not received any notification of any
examinations in progress relating to taxes for any period prior to the Closing.
To the Knowledge of the Stockholders, there are no claims against the Company
relating to Taxes for any period or periods prior to and including the Balance
Sheet Date. No written notice of any claim for Taxes, whether pending or
threatened, has been received. The Company has not granted or been requested to
grant any extension of the limitation period applicable to any claim for Taxes
or assessments with respect to Taxes. The Company is not a party to any Tax
allocation or sharing agreement and is not otherwise liable or obligated to
indemnify any person or entity with respect to any Taxes. The amounts shown as
accruals for Taxes on the Interim Financial Statements as of the Balance Sheet
Date are sufficient for the payment of all Taxes for all fiscal periods ended on
or before that date. True and complete copies of (a) any tax examinations, (b)
extensions of statutory limitations and (c) the federal, state and local Tax
returns of the Company for the last three fiscal years have been previously
provided to BVI. There are no requests for ruling in respect of any Tax pending
between the Company and any Taxing authority. The Company currently utilizes the
accrual method of accounting for income tax purposes. Such method of accounting
has not changed since November 1, 1994.

7.6. REGISTRATION STATEMENT ON FORM S-3.

         (a) As soon as reasonably practicable after the Closing (but without
obligation to do so earlier than September 11, 1998), BVI shall file with the
SEC a Registration Statement on Form S-3 or any successor short-form
registration statement promulgated by the SEC ("Registration Statement") to

1933 Act. After the Registration Statement is filed, BVI shall use reasonable
best efforts to (i) have the Registration Statement declared effective by the
SEC, (ii) thereafter prepare and file, as BVI shall determine may be required
under the 1933 Act and the rules and regulations thereunder, a prospectus

Statement or a post-effective amendment or amendments to the Registration
Statement and, with respect to any post-effective amendment, cause such
post-effective amendment to be declared effective by the SEC, (iii) maintain the
effectiveness of the Registration Statement until the earlier of (A) the date

to the underwriters of the Registrable Securities, if any, such reasonable
number of copies of the Registration Statement, preliminary prospectus and
prospectus supplement, final prospectus and 

                                       26
<PAGE>
 
prospectus supplement and such other documents as such Stockholders may
reasonably request in order to facilitate the public offering of the Registrable
Securities (ii) use its reasonable best efforts to register or qualify the
Registrable Securities covered by the Registration Statement under such state
securities or blue sky laws of such jurisdictions as the Stockholders may
reasonably request in writing within 20 days following the original filing of
the Registration Statement, except that BVI shall not for any purpose be
required to execute a general consent to service of process or to qualify to do
business as a foreign corporation in any jurisdiction wherein it is not so
qualified, (iii) notify the Stockholders, promptly after it shall receive notice
thereof, of the time when the Registration Statement has become effective or a

been filed, (iv) notify the Stockholders promptly of any request by the SEC for
the amending or supplementing of the Registration Statement or prospectus or
prospectus supplement or for additional information, (v) prepare and file with
the SEC, promptly upon the request of any Stockholder, any amendments or
supplements to the Registration Statement or prospectus or prospectus supplement
which, in the opinion of counsel for the Stockholders (and concurred in by
counsel for BVI), is required under the 1933 Act or the rules and regulations
thereunder in connection with the distribution of the Registrable Securities by
such Stockholder, (vi) prepare and promptly file with the SEC and promptly
notify the Stockholders of the filing of such amendment or supplement to the
Registration Statement or prospectus or prospectus supplement as may be
necessary to correct any statements or omissions if, at the time when a
prospectus relating to such securities is required to be delivered under the
1993 Act, any event shall have occurred as the result of which any such
prospectus or any other prospectus or prospectus supplement as then in effect
would include an untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in the light of the
circumstances in which they were made, not misleading, and (vii) advise the
Stockholders, promptly after BVI shall receive notice or obtain knowledge
thereof, of the issuance of any stop order by the SEC suspending the
effectiveness of the Registration Statement or the initiation or threatening of
any proceeding for that purpose and promptly use its reasonable best efforts to
prevent the issuance of any stop order or to obtain its withdrawal if such stop
order should be issued. Each Stockholder hereby agrees to cooperate with all
reasonable requests by BVI necessary to effectuate the preparation and filing of
the Registration Statement and agrees to provide the Company with all
information required in connection therewith in a timely manner and to comply
with the procedures specified in Section 7.6(b) below.

         (b) Prior to any sales of Registrable Securities under the Registration
Statement by a Stockholder, the Stockholder contemplating the sales will provide
BVI with written notice of such intention, addressed to BVI's Chief Financial
Officer (a "Sale Notice"). BVI will notify such Stockholder within two (2)
business days following receipt of the Sale Notice as to whether sales by the
Stockholder may be made or will be limited as provided below. Upon notice from
BVI permitting sales by the Stockholder, for a period beginning on the date of
receipt by the Stockholder of such notice and ending 45 days thereafter (the
"Window Period"), the Stockholder may offer and sell Registrable Securities from
time to time pursuant to the Registration Statement. Anything in this Agreement
to the contrary notwithstanding, the ability of a Stockholder to sell
Registrable Securities pursuant to the Registration Statement and this Agreement
shall be suspended in the event that, upon receiving a Sale Notice or during any
Window Period, BVI's Chief Financial Officer certifies to the Stockholders that,
in the good 

                                       27
<PAGE>
 
faith judgment of such officer (upon consultation to the extent practicable with
the Board of Directors of BVI to the extent practicable), (A) the sale would
interfere in any material respect with any financing, acquisition, corporate
reorganization or other similar material transaction under consideration by BVI,
or (B) there is some other material development relating to the condition
(financial or otherwise) of BVI that has not been generally publicly disclosed
and as to which BVI deems advisable upon the advice of counsel at the time of
the Sale Notice not to publicly disclose; provided, however, that, upon any such
event specified in (A) or (B) above, BVI may not suspend sales by Stockholders
under the Registration Statement for a period of more than forty-five (45) days
from the date of such certification by BVI's Chief Financial Officer. If, upon
receipt of the Sale Notice, BVI has reasonably determined that it is necessary
to file and cause to be declared effective a post-effective amendment to the
Registration Statement or file a new or amended prospectus supplement or to
otherwise cause disclosure to be made under the 1934 Act and incorporated by
reference into the Registration Statement, and BVI determines not to rely on the
proviso set forth in the preceding sentence in order to delay the making of such
disclosure, BVI will take such action within seven (7) business days following
receipt of the applicable Sale Notice.

         (c) If at any time following the date of this Agreement, BVI shall be
ineligible to register its securities on Form S-3 (other than by reason of gross
negligence or willful violation of BVI's covenant in Section 12.3(b) and 12.3(d)
hereof) then (i) BVI shall not be obligated to effect any registration of the
Registrable Securities under Section 7.6(a) until such time as BVI becomes
eligible to use Form S-3 (provided, however, that if at the time such
eligibility is restored all of the Registrable Securities held by a Stockholder
are then eligible for sale during any given three (3) month period under Rule
144 under the Securities Act, BVI will have no further registration obligation
under Section 7.6(a) with respect to such Stockholder's Registrable Securities);
and (ii) if the Registration Statement has become effective under the 1933 Act,
BVI may file an amendment to the Registration Statement deregistering any
Registrable Securities remaining unsold at the time that BVI became ineligible
to use Form S-3. In the event that BVI becomes ineligible to use Form S-3
through its gross negligence or willful misconduct and such ineligibility
remains uncured for a period of 10 days, BVI's obligation to register the
Registrable Securities will be deemed to extend to registration on Form S-1, S-2
or other applicable forms promulgated by the SEC. BVI will provide prompt notice
to the Stockholders of any ineligibility to use Form S-3 and of any
deregistration of the Registrable Securities under this Section.

         (d) In connection with the registration of the Registrable Securities,
BVI shall bear the following fees, costs and expenses: all registration, filing
NASD and Nasdaq National Market or exchange listing fees, printing expenses,
fees and disbursements of counsel and accountants for BVI, all internal BVI
expenses and all legal fees and disbursements and other expenses of complying
with state securities or blue sky laws of any jurisdictions in which the
Registrable Securities are to be registered or qualified. Fees and disbursements
of counsel and accountants for the Stockholders, underwriting discounts and
commissions and transfer taxes relating to the Registrable Securities included
in the offering, and any other expenses incurred by the Stockholders not
expressly included above, shall be borne by the Stockholders.

         (e) With respect to such registration:

                                       28
<PAGE>
 
             (i) Subject to compliance by a holder of Registrable Securities
             with Section 7.6(b), BVI will indemnify and hold harmless each
             holder of Registrable Securities which are included in the
             Registration Statement, and any underwriter (as defined in the 1933
             Act) for such holder and each person, if any, who controls such
             holder or such underwriter within the meaning of the 1933 Act, from
             and against, and will reimburse such holder and each such
             underwriter and controlling person with respect to, any and all
             loss, damage, liability, cost and expense to which such holder or
             any such underwriter or controlling person may become subject under
             the 1933 Act or otherwise, insofar as such losses, damages,
             liabilities, costs or expenses are caused by any untrue statement
             or alleged untrue statement of any material fact contained in the
             Registration Statement, any prospectus or prospectus supplement
             contained therein or any amendment or supplement thereto, or arise
             out of or are based upon the omission or alleged omission to state
             therein a material fact required to be stated therein or necessary
             to make the statements therein, in light of the circumstances in
             which they were made, not misleading; provided, however, that BVI
             will not be liable in any such case to the extent that any such
             loss, damage, liability, cost or expense arises out of or is based
             upon an untrue statement or alleged untrue statement or omission or
             alleged omission so made in conformity with information furnished
             by such holder, such underwriter or such controlling person in
             writing specifically for use in the preparation thereof.

             (ii) Each holder of Registrable Securities which are included in
             the Registration Statement will indemnify and hold harmless BVI,
             its directors and officers, and any controlling person thereof and
             any underwriter from and against, and will reimburse BVI, its
             directors and officers, and any such controlling person and any
             underwriter with respect to, any and all loss, damage, liability,
             cost or expense to which BVI or any controlling person and any
             underwriter may become subject under the 1933 Act or otherwise,
             insofar as such losses, damages, liabilities, costs or expenses are
             caused by any untrue or alleged untrue statement of any material
             fact contained in the Registration Statement, any prospectus or
             prospectus supplement contained therein or any amendment or
             supplement thereto, or arise out of or are based upon the omission
             or the alleged omission to state therein a material fact required
             to be stated therein or necessary to make the statements therein,
             in light of the circumstances in which they were made, not
             misleading, in each case to the extent, but only to the extent,
             that such untrue statement or alleged untrue statement or omission
             or alleged omission was so made in reliance upon and in strict
             conformity with written information furnished by such holder
             specifically for use in the preparation thereof.

         (f) For the purposes of this Section 7.6, the term "Registrable
Securities" shall mean (i) the Restricted Shares, and (ii) any BVI Common Stock
issued or issuable with respect to such Restricted Shares by way of a stock
dividend or stock split or in connection with a combination of shares,
recapitalization, merger, consolidation or other reorganization or a sale of
substantially all of BVI's assets.

7.9. INSURANCE. In the event BVI or Newco determines to cancel or reduce any of
the insurance coverages described on Schedule 7.9, the effect of which may
result in an increase in the Stockholders' indemnification obligations
hereunder, each of BVI and Newco shall use its reasonable best efforts to
provide the Stockholders with notice of such action at least 30 days prior to

Wright and John Reed shall have the option, for a period of five (5) business
days after the Closing Date, to assume the key man life insurance policy or
policies currently held by the Company on such person's life and the Surviving
Corporation will permit any such transfer and will take all actions necessary to
release and terminate the interest of Norwest Bank Minnesota, N.A. in such
policies and will take all other actions (at no cost to the Surviving
Corporation) reasonably requested to facilitate such purchase.


                                  ARTICLE VIII
                                 INDEMNIFICATION

The Stockholders, BVI and Newco each make the following covenants:

8.1. GENERAL INDEMNIFICATION BY THE STOCKHOLDERS.

         (a) Subject to Section 8.4, each of the Stockholders covenants and
agrees that such Stockholder will severally indemnify, defend, protect and hold
harmless BVI, Newco and the Surviving Corporation, and their respective
officers, directors, employees, stockholders, agents, representatives and
Affiliates, from and against all Losses incurred by any of such indemnified
persons as a result of or arising from (i) any breach of the representations and
warranties of such Stockholder set forth in Sections 5.31, 5.32, 12.1 and 12.2,
(ii) any breach or nonfulfillment of any covenant or agreement on the part of
such Stockholder under this Agreement, and (iii) all transfer taxes arising from
the transactions contemplated by this Agreement (for each Stockholder, the items
listed in clauses (i), (ii) and (iii), referred to collectively as such
Stockholder's "Individual Stockholder Indemnification Obligations").

         (b) Subject to Section 8.4, the Stockholders covenant and agree that
they will jointly and severally indemnify, defend, protect and hold harmless
BVI, Newco and the Surviving Corporation, and their respective officers,
directors, employees, stockholders, agents, representatives and Affiliates, from
and against all Losses incurred by any of such indemnified 

                                       30
<PAGE>
 
persons as a result of or arising from any breach of the representations and
warranties of the Stockholders set forth in Article V except those set forth in
Sections 5.31 and 5.32.

An escrow fund to be funded in cash in the amount of $100,000 shall be
established at Closing (the "Escrow") pursuant to the terms of the Escrow
Agreement attached to this Agreement as Schedule 8.1., such fund to be comprised
of $85,000 contributed by Ronald Breckner and $15,000 contributed by James Pfau
(such amounts to be deducted from the Merger Consideration due each of them at
Closing).

8.2. INDEMNIFICATION BY BVI. Subject to Section 8.4, BVI , Newco and the
Surviving Corporation covenant and agree that they will jointly and severally
indemnify, defend, protect and hold harmless the Stockholders and their
respective agents, representatives, Affiliates, beneficiaries and heirs and
employees from and against all Losses incurred by any of such indemnified
persons as a result of or arising from (a) any breach of the representations and
warranties of BVI or Newco set forth herein, (b) any breach or nonfulfillment of
any covenant or agreement on the part of BVI or Newco under this Agreement, and
(c) any facts or circumstances first arising, or actions or inactions of the
Surviving Corporation or BVI occurring solely after the Closing which result in
liability to the Stockholders as a result of their former capacities as
officers, directors or shareholders of the Company.

8.3. THIRD PERSON CLAIMS. Promptly after any party hereto (hereinafter the
"Indemnified Party") has received notice of or has knowledge of any claim by a
person not a party to this Agreement ("Third Person"), of the commencement of
any action or proceeding by a Third Person, which the Indemnified Party believes
in good faith is an indemnifiable claim under this Agreement, the Indemnified
Party shall give to the party obligated to provide indemnification pursuant to
Section 7.6, 8.1, or 8.2 hereof (hereinafter the "Indemnifying Party") written
notice of such claim or the commencement of such action or proceeding; provided,
that the failure of the Indemnified Party promptly to notify the Indemnifying
Party of any such matter shall not release the Indemnifying Party, in whole or
in part, from its obligations under Section 7.6 or this Article VIII except to
the extent the Indemnified Party's failure to so notify in breach of this
paragraph materially prejudices the Indemnifying Party's ability to defend
against such third party claim or litigation. Such notice shall state the nature
and the basis of such claim. The Indemnifying Party shall have the right to
defend and settle, at its own expense and by its own counsel, any such matter so
long as the Indemnifying Party pursues the same diligently and in good faith. If
the Indemnifying Party undertakes to defend or settle, it shall promptly notify
the Indemnified Party of its intention to do so, and the Indemnified Party shall
cooperate with the Indemnifying Party and its counsel in all commercially
reasonable respects in the defense thereof and in any settlement thereof. Such
cooperation shall include, but shall not be limited to, furnishing the
Indemnifying Party with any books, records and other information reasonably
requested by the Indemnifying Party and in the Indemnified Party's possession or
control. After the Indemnifying Party has notified the Indemnified Party of its
intention to undertake to defend or settle any such asserted liability, and for
so long as the Indemnifying Party diligently pursues such defense, the
Indemnifying Party shall not be liable for any additional legal expenses
incurred by the Indemnified Party in connection with any defense or settlement
of such asserted liability; provided, however, that the Indemnified Party shall
be entitled, at its expense, to participate in the defense of such asserted
liability and the negotiations of the settlement thereof 

                                       31
<PAGE>
 
and provided, further, if the defendants in any action include both the
Indemnified Party and the Indemnifying Party and the Indemnified Party shall
have reasonably concluded that there may be legal defenses available to it
and/or other indemnified parties which are different from or additional to those
available to the Indemnifying Party, or if there is a conflict of interest which
would prevent counsel for the Indemnifying Party from also representing the
Indemnified Party, the Indemnified Party or parties shall have the right to
select separate counsel to participate in the defense of such action on behalf
of such Indemnified Party or Parties, at the expense of the Indemnifying Party.
The Indemnifying Party shall not settle any such Third Person claim without the
consent of the Indemnified Party, unless the settlement thereof imposes no
liability or obligation on, and includes a complete release from liability of,
the Indemnified Party. If the Indemnifying Party desires to accept a final and
complete settlement of any such Third Person claim and the Indemnified Party
refuses to consent to such settlement, then the Indemnifying Party's liability
under this Section with respect to such Third Person claim shall be limited to
the amount so offered in settlement by said Third Person; provided, however,
that notwithstanding the foregoing, the Indemnified Party shall be entitled to
refuse to consent to any such proposed settlement and the Indemnifying Party's
liability hereunder shall not be limited by the amount of the proposed
settlement if such settlement does not provide for the complete release of the
Indemnified Party. If, upon receiving notice, the Indemnifying Party does not
undertake to defend such matter within thirty (30) days to which the Indemnified
Party is entitled to indemnification hereunder, or fails diligently to pursue
such defense, the Indemnified Party may undertake such defense through counsel
of its choice, at the cost and expense of the Indemnifying Party, and the
Indemnified Party may settle such matter, in its sole and absolute discretion,
and the Indemnifying Party shall reimburse the Indemnified Party to the extent
the amount paid in such settlement and any other liabilities or expenses
incurred by the Indemnified Party in connection therewith are indemnifiable
Losses under this Agreement. Except as provided in writing to such effect signed
by such person, no action or inaction of an Indemnifying Party under this
Section 8.3 shall be deemed a waiver of such person's right to contest any claim
for indemnification under this Agreement.

8.4. INDEMNIFICATION DEDUCTIBLE. In no event shall any Stockholder be liable
under Section 8.1(b) hereof unless the Losses therefrom exceed $100,000 and then
only to the extent the Losses exceed $100,000. The parties hereto acknowledge
and agree that each of Willard Sykes and Catherine Sykes shall only have
indemnification obligations pursuant to Section 8.1(a) with respect to
Individual Stockholder Indemnification Obligations and will not have
indemnification obligations pursuant to Section 8.1(b) as a result of any
breaches of any representation and warranties contained in Article V hereof
other than those made by such Stockholders in Section 5.31. In no event shall
the liability of any Stockholder for Losses resulting from such Stockholder's
Individual Stockholder Indemnification Obligations (other than Losses resulting
from a breach of the terms and conditions of Sections 9.1 or 10.1 of this
Agreement), exceed the following amounts:

                                       32
<PAGE>
 
                           G. Nelson, Jr. - $1,127,500
                            R. Breckner - $1,100,000
                               J. Pfau - $357,500
                                W. Sykes $82,500
                                C. Sykes $82,5000

In no event shall the liability of any Stockholder for all Losses pursuant to
Section 8.1 hereof, (other than Losses resulting from a breach of the terms and
conditions of Sections 9.1 or 10.1 of this Agreement) including and together
with any liability for Losses for which such Stockholder is responsible pursuant
to the preceding sentence, exceed the following amounts:

                           G. Nelson, Jr. - $1,174,250
                            R. Breckner - $1,146,750
                               J. Pfau - $429,000.

In no event shall the liability of any Stockholder for Losses resulting from
such Stockholder's breach of the terms and conditions of Sections 9.1 and 10.1
of this Agreement exceed the following amounts:

                           G. Nelson, Jr. - $2,750,000
                            R. Breckner - $2,750,000
                              J. Pfau - $2,750,000
                               W. Sykes $2,750,000
                               C. Sykes $2,750,000

In no event shall BVI, Newco and the Surviving Corporation be liable under
Section 8.2 hereof, unless the Losses therefrom exceed $100,000 and then only to
the extent the Losses exceed $100,000. In no event shall the liability of BVI,
Newco and the Surviving Corporation for Losses pursuant to Section 8.2 hereof
exceed $2,750,000 in the aggregate.

8.5. SUBROGATION. At the Stockholders' joint election, the Stockholders shall be
subrogated to any claims or rights of BVI or Newco as against any other persons
with respect to any Losses paid by any Stockholder under this Article VIII;
provided that the Stockholders vigorously pursue such claim against such other
persons and pay to BVI or Newco, as appropriate, all amounts received from such
other persons until such time as BVI's or Newco's Losses have been reduced to
zero and provided further, that the obligations of the Stockholders to BVI,
Newco and the Surviving Corporation in accordance with Section 8.1 of this
Agreement shall not be contingent upon or delayed by the Stockholders' pursuit
of any subrogated claims in accordance with this Section 8.5. BVI and Newco
shall cooperate with the Stockholders, to the extent reasonable under the
circumstances, at the sole expense of Stockholders, in connection with the
assertion by the Stockholders of any such claim against any such other persons;
provided that BVI and Newco shall not be required to institute litigation or
file any claim in a proceeding.

8.6. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations and
warranties set forth in ARTICLE V and ARTICLE VI shall survive the Closing for a
period of eighteen months from the Closing Date (the "Expiration Date"), except
that the representations and warranties set 

                                       33
<PAGE>
 
forth in SECTIONS 5.3, 5.16, 5.18, 5.31(B) AND 5.32(A) hereof shall survive the
transaction contemplated by this Agreement and not terminate and the Expiration
Date shall not be applicable to said representations. Notwithstanding anything
in this Article VIII to the contrary, an Indemnifying Party's indemnification
obligations under Article VIII shall not terminate as of the Expiration Date
with respect to any claims for indemnification to which the Expiration Date
would otherwise be applicable which are asserted in writing prior to the
Expiration Date and have not been finally resolved prior to the Expiration Date.

8.7. ADDITIONAL NOTICE; COOPERATION. In addition to any notice which BVI, the
Surviving Corporation or Newco may give to the Stockholders pursuant to this
Article VIII, BVI, the Surviving Corporation and Newco agree that they shall
give written notice to the Stockholders promptly upon the receipt by BVI, the
Surviving Corporation or Newco of knowledge of a state of facts which, if not
corrected, would in BVI's, the Surviving Corporation's or Newco's judgment be
reasonably likely to become the subject of a claim for indemnification
hereunder; provided, that the failure of BVI, the Surviving Corporation or Newco
promptly to notify the Stockholders of any such matter shall not release the
Stockholders, in whole or in part, from their obligations under this Article
VIII.

8.8. EXCLUSIVE REMEDY. The indemnification provisions of this Article VIII shall
be the sole and exclusive remedy of BVI, Surviving Corporation, Newco and the
Stockholders relative to the matters set forth herein and are in lieu of any
other statutory, equitable, common law or other remedy BVI, Surviving
Corporation, Newco or the Stockholders may have relative to the matters set
forth therein, other than claims for specific performance or other equitable
relief pursuant to Sections 9.2 and 10.2 and other than claims based in fraud
and other than claims made pursuant to Section 7.6.


                                   ARTICLE IX
                            NONCOMPETITION COVENANTS

9.1 PROHIBITED ACTIVITIES.

         (a) For the additional consideration of $950,000 to be allocated among
the Stockholders in accordance with Schedule 9.1, each Stockholder hereby agrees
that such Stockholder will not for ten years following the Closing Date directly
or indirectly, for himself or on behalf of or in conjunction with any other
person, company, partnership, corporation or business of whatever nature:

             (i)   engage, as an officer, director, shareholder, owner, partner,
                   joint venturer, or in a managerial or advisory capacity,
                   whether as an employee, independent contractor, consultant or
                   advisor, or as a sales representative, in the Business any
                   where in the world (such areas being herein referred to as
                   the "Territory");

             (ii)  call upon any person, who is, at that time, an employee or
                   consultant of BVI or the Surviving Corporation or any of
                   their respective subsidiaries, 

                                       34
<PAGE>
 
                   for the purpose or with the intent or effect of enticing such
                   employee or consultant away from or out of the employ or
                   contract with BVI or the Surviving Corporation or any of
                   their respective subsidiaries; or

             (iii) call upon any person or entity which is, at that time, or
                   which has been, within one year prior to that time, a
                   customer of the Company, BVI or the Surviving Corporation or
                   any of the subsidiaries of such parties within the Territory
                   for the purpose of soliciting or selling services or products
                   in the Business within the Territory.

         (b) Notwithstanding the above, Section 9.1(a) shall not be deemed to
prohibit any Stockholder from acquiring, as a passive investor with no
involvement in the operations of the business, not more than 4.99 percent of the
capital stock of an entity engaged in the Business.

9.2. EQUITABLE RELIEF. Because of the difficulty of measuring economic losses to
BVI and the Surviving Corporation as a result of a breach of the foregoing
covenant, because a breach of such covenant would diminish the value of the
Company being sold pursuant to this Agreement, and because of the immediate and
irreparable damage that could be caused to BVI and the Surviving Corporation for
which they would have no other adequate remedy, each Stockholder agrees that the
foregoing covenant may be enforced against such individual by injunctions,
restraining orders and other equitable actions.

9.3. REASONABLE RESTRAINT. It is agreed by the parties hereto that the foregoing
covenants in this ARTICLE IX are necessary in terms of time, activity and
territory to protect BVI's and the Surviving Corporation's interest in the
shares being acquired pursuant to the terms of this Agreement and impose a
reasonable restraint on each Stockholder in light of the activities and
businesses of the Company on the date of the execution of this Agreement and the
current plans of the Company.

9.4. SEVERABILITY; REFORMATION. The covenants in this ARTICLE IX are severable
and separate, and the unenforceability of any specific covenant shall not affect
the continuing validity and enforceability of any other covenant. In the event
any court of competent jurisdiction shall determine that the scope, time or
territorial restrictions set forth in this ARTICLE IX are unreasonable and
therefore unenforceable, then it is the intention of the parties that such
restrictions be enforced to the fullest extent which the court deems reasonable
and this Agreement shall thereby be reformed.

9.5. MATERIAL AND INDEPENDENT COVENANT. Each Stockholder acknowledges that his
or her agreements and the covenants set forth in this ARTICLE IX are material
conditions to BVI's and Newco's agreements to execute and deliver this Agreement
and to consummate the transactions contemplated hereby and that BVI and Newco
would not have entered into this Agreement without such covenants. All of the
covenants in this ARTICLE IX shall be construed as an agreement independent of
any other provision in this Agreement.

                                    ARTICLE X
                    NONDISCLOSURE OF CONFIDENTIAL INFORMATION

10.1 GENERAL. Each Stockholder recognizes and acknowledges that he or she has in
the past or currently has access to certain confidential information relating to
the businesses of the Company, such as lists of customers, operational policies,
and pricing and cost policies that are, and following the Closing will be,
valuable, special and unique assets of the Surviving Corporation. Each
Stockholder agrees that he or she will not use or disclose such confidential
information to any person, firm, corporation, association or other entity for
any purpose whatsoever, except as is required in the course of performing his or
her duties, if any, to the Surviving Corporation and/or BVI, unless (a) such
information becomes known to the public generally through no fault of such
Stockholder, or (b) disclosure is required by Law, provided that prior to
disclosing any information pursuant to this clause (b) such Stockholder shall,
if possible, give prior written notice thereof to BVI and the Surviving
Corporation and provide BVI with the opportunity to contest such disclosure. In
the event of a breach or threatened breach by any Stockholder of the provisions
of this Section, BVI shall be entitled to an injunction restraining such
Stockholder from disclosing, in whole or in part, such confidential information.
Nothing herein shall be construed as prohibiting BVI from pursuing any other
available remedy for such breach or threatened breach, including, without
limitation, the recovery of damages.

10.2. EQUITABLE RELIEF. Because of the difficulty of measuring economic losses
as a result of the breach of the foregoing covenants, because a breach of such
covenant would diminish the value of the Company being sold pursuant to this
Agreement, and because of the immediate and irreparable damage that would be
caused for which the Surviving Corporation and/or BVI would have no other
adequate remedy, each Stockholder agrees that the foregoing covenants may be
enforced against him or her by injunctions, restraining orders and other
equitable actions.


                                   ARTICLE XI
                             INTENDED TAX TREATMENT

11.1 TAX-FREE REORGANIZATION. BVI and the Stockholders are entering into this
Agreement with the intention that the Merger qualify as a tax-free
reorganization within the meaning of Section 368(a)(2)(D) of the Code for
federal income tax purposes, except to the extent of any "boot" received, and
neither BVI nor the Stockholders will take any actions that disqualify the
Merger for such treatment. Notwithstanding the foregoing, the parties
acknowledge that none of them has filed a request for a private letter ruling
with the Internal Revenue Service that the Merger is a tax-free reorganization
within the meaning of Section 368(a) of the Code. In the event of a final
determination by the Internal Revenue Service that the Merger is not a tax-free
reorganization, BVI and the Surviving Corporation hereby agree that (i) they,
and not the Stockholders, shall be responsible for any taxes, interest and
penalties that would result from the taxation of the Company, and (ii) the
Stockholders, and not BVI or the Surviving Corporation, shall be responsible for
any taxes, interest and penalties resulting from their status as stockholders of
the Company or from their receipt of the Merger Consideration in the Merger.

                                   ARTICLE XII
           FEDERAL SECURITIES ACT OF 1933 AND CONTRACTUAL RESTRICTIONS
                               ON BVI COMMON STOCK

12.1 COMPLIANCE WITH LAW. Each of the Stockholders acknowledges that the shares
of BVI Common Stock issued at the Closing in accordance with the terms of this
Agreement (the "Restricted Shares") will not as of the Closing Date be
registered under the 1933 Act and therefore may not be resold without compliance
with the 1933 Act. The Restricted Shares are being or will be acquired by each
of the Stockholders solely for his or her own account and without a view to
distribution within the meaning of the 1933 Act. Each of the Stockholders
covenants, warrants and represents that none of the Restricted Shares will be,
directly or indirectly, offered, sold, assigned, pledged, hypothecated,
transferred or otherwise disposed of except after full compliance with all of
the applicable provisions of the 1933 Act and the rules and regulations
thereunder. Certificates representing the Restricted Shares shall bear a legend
in substantially the following language:

         THE SHARES REPRESENTED BY THIS CERTIFICATE WERE NOT ISSUED IN A
         TRANSACTION REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
         ("1933 ACT"), OR ANY APPLICABLE STATE SECURITIES LAWS. THE SHARES
         REPRESENTED HEREBY HAVE BEEN ACQUIRED WITHOUT A VIEW TO DISTRIBUTION
         WITHIN THE MEANING OF THE 1933 ACT AND MAY NOT BE SOLD OR TRANSFERRED
         UNLESS SUCH SALE OR TRANSFER IS COVERED BY AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE 1933 ACT AND APPLICABLE STATE SECURITIES LAWS OR,
         IN THE OPINION OF COUNSEL TO THE ISSUER, IS EXEMPT FROM THE
         REGISTRATION REQUIREMENTS OF THE 1933 ACT AND SUCH LAWS.

12.2. ECONOMIC RISK; SOPHISTICATION. Each Stockholder is able to bear the
economic risk of an investment in the Restricted Shares and can afford to
sustain a total loss of such investment. Each Stockholder represents to BVI and
Newco that such Stockholder is an "accredited investor," as that term is defined
in Regulation D under the 1933 Act for the reasons specified on such
Stockholder's Certification, the form of which is attached hereto as Schedule
12.2. Each Stockholder or her or his representatives have had an adequate
opportunity to ask questions and receive answers from the officers of BVI and
Newco concerning, among other matters, BVI, its management, its plans for the
operation of its business and potential additional acquisitions.

12.3. RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the SEC that may permit the resale of BVI
Common Stock to the public without registration and to maintain eligibility for
the use of Form S-3, for a period of two years after the Closing, BVI agrees to
use its commercially reasonable efforts to:

         (a) make and keep current public information (as contemplated by Rule
144) regarding BVI available;

         (b) file with the SEC in a timely manner all reports and other
documents required of BVI under the 1933 Act and the 1934 Act;

                                       37
<PAGE>
 
         (c) furnish to each Stockholder upon written request a written
statement by BVI as to its compliance with the reporting requirements of Rule
144, the 1933 Act and the 1934 Act, a copy of the most recent annual or
quarterly report of BVI, and such other reports and documents so filed as such
Stockholder may reasonably request in availing himself of any rule or regulation
of the SEC allowing such Stockholder to resell any such shares without
registration; and

         (d) not fail to pay any dividend or sinking fund installment on
preferred stock or default on either (a) any installment on indebtedness for
borrowed money or (b) on any rental on long term leases, which defaults in the
aggregate are material to the consolidated financial position of BVI.


                                  ARTICLE XIII
                                  MISCELLANEOUS

13.1 SUCCESSORS AND ASSIGNS. This Agreement and the rights of the parties
hereunder may not be assigned (except by operation of Law) and shall be binding
upon and shall inure to the benefit of the parties hereto, the successors of
BVI, Newco, the Surviving Corporation and the Company, and the heirs and legal
representatives of the Stockholders.

13.2. ENTIRE AGREEMENT. Except as referenced on Schedule 13.2, this Agreement
(including the Schedules, exhibits and annexes attached hereto) and the
documents delivered pursuant hereto constitute the entire agreement and
understanding among the Stockholders, the Company, Newco and BVI and supersede
any prior agreement and understanding relating to the subject matter of this
Agreement. Except for the representations and warranties of BVI, Newco, the
Company and the Stockholders, which are contained in this Agreement, there are
no other representations and warranties by or on behalf of BVI, Newco, the
Company or the Stockholders which are being relied upon by the parties hereto.
Any provision of this Agreement may be modified, amended or waived only by a
written instrument duly executed by the Stockholders, the Company, Newco and BVI
in the case of an amendment or modification, or by the party against whom the
waiver is to be effective, in the case of a waiver.

13.3. COUNTERPARTS. This Agreement may be executed simultaneously in two or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute but one and the same instrument.

13.4. BROKERS AND AGENTS. Except as set forth on Schedule 13.4, each party
hereto represents and warrants that it employed no broker or agent (collectively

<PAGE>
 
defined in Paragraph 4.1 of this Agreement, or (ii) a change in control as
defined in the Change in Control Agreement attached hereto as Exhibit B (the
"Change in Control Agreement"), the Executive shall receive:

         (a)    a cash severance payment equal to the difference between the
                amount of Base Salary the Executive was actually paid between
                the date of this Agreement and the date of the Executive's
                termination of employment, and the total amount of Base Salary
                that Executive was entitled to receive pursuant to the terms of
                this Agreement if the Executive were employed for the full
                amount of the Original Term (the "Termination Payment"). This
                Termination Payment will be payable in equal payments during the
                period between the date of the Executive's termination and the
                expiration of the Original Term (the "Severance Term") in
                accordance with the Employer's customary wage payment policies
                and practices and shall be subject to federal and state tax
                withholding and FICA.

         (b)    The Employer will also provide to the Executive, at the
                Employer's expense, group medical and dental insurance during
                the Severance Term in an amount equal to that portion of such
                benefits that the Employer paid the Executive for such benefits
                immediately preceding the date of the Executive's termination
                (the "Employer Contribution Amount"), it being acknowledged and
                agreed that such Employer Contribution Amount will be paid
                directly to the Employer's insurer for any such benefits to be
                paid during the first eighteen months following the date of
                termination of Employment and, if necessary, directly to the
                Executive thereafter.

         (c)    In addition to the group medical and dental paid to Executive
                during the Severance Term, subject to the condition that the
                Employer's disability insurance plan permits such participation
                by the Executive, the Employer will provide to the Executive
                during the Severance Term, at the Employer's expense, in an
                amount equal to the Employer Contribution Amount, group
                disability insurance. However, nothing herein obligates the
                Employer to modify or amend in any manner whatsoever its
                disability insurance plan to accommodate the Executive, although
                the Employer may make such modifications or amendments, at its
                sole discretion, if it is consistent with the Employer's
                developing employment policies.

         (d)    In addition to the group medical, dental and disability benefits
                paid to the Executive during the Severance Term, subject to the
                condition that the applicable Employer's plans permit such
                participation by the Executive, the Employer will provide to the
                Executive, at the Employer's expense, in an amount equal to the
                Employer Contribution Amount, group medical, dental, life and
                disability insurance for the period between the expiration date
                of the Severance Term and the later date of (i) the third
                anniversary of the date of the termination of the Executive's
                employment or (ii) the date the Executive has attained age 62.

                                      -3-
<PAGE>
 
                However, nothing herein obligates the Employer to modify or
                amend in any manner whatsoever its health, dental, life and
                disability insurance plans to accommodate the Executive,
                although the Employer may make such modifications or amendments,
                at its sole discretion, if it is consistent with the Employer's
                developing employment policies.

Notwithstanding any other provision of this Section 2.5, in the event the
Severance Term is less than six (6) months and the employment of the Executive
is terminated as provided in the first paragraph of this Section 2.5, the
Executive shall receive (i) six (6) months of Base Salary as of the date of
termination of employment in equal payments over the six month period in
accordance with the Employer's customary wage payment practices and policies,
and (ii) six (6) months of group medical, dental and disability insurance at the
Employer Contribution Amount.

It is specifically acknowledged and agreed that (i) in the event Executive
resigns, Executive shall not be entitled to any Termination Payment, and (ii) in
the event Executive's employment is terminated by the Employer for any reason,
Executive shall not be entitled to a pro-rata cash incentive bonus as provided
in Section 2.2 of this Agreement.

In consideration for the payments provided in this Section 2.5, Executive agrees
to execute a release of any and all claims against the Employer, at the time of
termination of the Executive's employment, the release to be in such reasonable
form as prepared by the Employer.

2.6. RESTRICTED STOCK COMPENSATION. The Employer hereby grants to the Executive
that number of shares BVI common stock as determined by (a) multiplying the
Executive's Base Salary on the Commencement Date by 10%, then (b) multiplying
such amount by the sum of 3 plus the number of months remaining in fiscal year
1998 divided by 12, then (c) dividing such amount by the closing bid price
(hereinafter, the "Stock Price") of BVI common stock on the Commencement Date.
Such stock shall vest in four (4) installments on each of October 31, 1998,
1999, 2000 and 2001, as long as the Executive continues to be employed by the
Employer. The number of shares to vest on October 31, 1998 shall be the product
of (a) 10% of the Executive's Base Salary on the Commencement Date multiplied by
(b) the ratio of the number of months remaining in fiscal year 1998 by 12. The
remainder of such stock shall vest in three (3) equal installments on October
31, 1999, 2000 and 2001. Such stock will contain such restrictions or other
provisions as are applicable to other similarly circumstanced Executives issued
restrictive stock as part of their compensation plans.

2.7.     STOCK OPTIONS.

         (a)    The Employer hereby grants to the Executive an option to
                purchase that number of shares of BVI common stock as determined
                by (a) multiplying the Executive's Base Salary on the
                Commencement Date by 20%, then (b) multiplying such 

                                      -4-
<PAGE>
 
                amount by the sum of 3 plus the number of months remaining in
                fiscal year 1998 divided by 12, then (c) dividing such amount by
                the Stock Price of BVI common stock on the Commencement Date.
                Such option shall become exercisable in four increments on
                October 31, 1998, 1999, 2000 and 2001, as long as the Executive
                continues to be employed by the Employer. The number of shares
                to become exercisable on October 31, 1998 shall be determined by
                multiplying 20% of the Executive's Base Salary on the
                Commencement Date by a fraction, the numerator of which is the
                number of months remaining in fiscal year 1998, and the
                denominator of which is 12. The remainder of such options will
                become exercisable in equal installments on October 31, 1999,
                2000 and 2001. The terms of the option will be governed by a
                separate stock option agreement to be delivered at the time the
                option is granted.

         (b)    On the Commencement Date the Employer will grant to the
                Executive an option to purchase 7,000 shares of BVI common
                stock. The terms of the option will be governed by a separate
                stock option agreement to be delivered at the time the option is
                granted. The option shall become exercisable on the fourth
                anniversary of the Commencement Date, as long as the Executive
                is employed by the Employer on the fourth anniversary of the
                Commencement Date.

2.8. CHANGE IN CONTROL. The Executive shall be entitled to certain benefits upon
a change in control as defined in and in accordance with the terms of the Change
in Control Agreement attached hereto as Exhibit B.

                                      -5-

2.9 REIMBURSEMENT OF EXPENSES. The Employer shall reimburse the Executive for
all reasonable, ordinary and necessary expenses incurred by him in the
performance of his duties hereunder and the Executive shall account to the
Employer therefor in the manner normally prescribed by the Employer for
reimbursement of Executive expenses.

                               DUTIES OF EXECUTIVE

3.1 SERVICES. The Executive shall perform all duties and obligations charged to
the Executive by the Board of Directors of the Employer, as the same may be
determined from time to time, provided, however, that it is acknowledged and
agreed that the President and Chief Executive Officer of BVI shall direct the
Executive's day-to-day activities. The Board shall assure adequate time,
resources and authority for the Executive to achieve goals mutually agreed upon
by the Employer and the Executive.

3.2 TIME AND EFFORT. The Executive shall devote his full time and effort to the
business of the Employer, provided, however, that Executive shall be allowed to
continue to serve as both (i) a member of an advisory group for U.M.C., Inc., a
private machine shop and (ii) a director of INNOVATIVE CUISINE, INCORPORATED
d/b/a FIVE STAR FOOD BASE COMPANY. The Executive shall perform the duties and
obligations required of the Executive hereunder in a competent, efficient and
satisfactory manner at such hours and under such conditions as the performance
of such duties and obligations may require.

3.3 ARTICLES AND BY-LAWS. The Executive shall act in accordance with and so as
to abide by the Articles of Incorporation of the Employer, the Bylaws of the
Employer and all decisions of the Board of Directors of the Employer.

3.4 CONFIDENTIALITY AND LOYALTY. Executive acknowledges that, during the course
of his employment he has produced and may produce and have access to material,
records, data and information not generally available to the public
("Confidential Information") regarding the Employer, its customers and
affiliates. Accordingly, during and subsequent to the termination of this
Agreement, Executive shall hold in confidence and not directly or indirectly
disclose, use, copy or make lists of any such confidential information, except
to the extent authorized in writing by the Employer, or as required by law or
any competent administrative agency or as otherwise is reasonably necessary or
appropriate in connection with the performance by Executive of his duties
pursuant to this Agreement. Upon termination of his employment under this
Agreement, Executive shall promptly deliver to the Employer (i) all records,
manuals, books, documents, letters, reports, data, tables, calculations and all
copies of any of the foregoing which are the property of Employer or which
relate in any way to the customers, business, practices or techniques of the
Employer and (ii) all other property of Employer and Confidential Information
which in any of these cases are in his possession or 

                                      -6-
<PAGE>
 
under his control. Executive agrees to abide by the Employer's reasonable
policies as in effect from time to time, respecting avoidance of interests
conflicting with those of the Employer.

3.5 COVENANT NOT TO COMPETE. In exchange for the consideration (i) received by
the Executive in accordance with the terms of the Merger Agreement and (ii)
given by Employer to Executive pursuant to this Agreement, specifically
including, but not limited to, the Severance Payment provided in Section 2.5 of
this Agreement, Executive agrees, represents to and covenants with the Employer
that during the period of Executive's employment by or with Employer, and for
the longer of (i) a period of one (1) year immediately following the termination
of Executive's employment with Employer under this Agreement or otherwise, and
(ii) ten (10) years following the Closing Date (as such term is defined in the
Merger Agreement), for any reason whatsoever, either directly or indirectly, for
himself or on behalf of or in conjunction with any other person, persons,
Employer, partnership, corporation or business of whatever nature violate the
noncompetition covenants of Article IX of the Merger Agreement, which are hereby
incorporated by reference in this Agreement in their entirety.

3.6. CREATIONS. Subject to Executive's rights under Minnesota Statutes ss.
181.78, Executive hereby agrees that every idea, concept, invention and
improvement (whether patented or not) conceived by Executive and all copyrighted
or copyrightable matter created by Executive that relates to the Employer's
business (collectively, "Creations") shall be the property of the Employer (or
its designee). Executive shall communicate promptly and disclose to the
Employer, in such form as the Employer may request, all information, details and
data pertaining to each Creation. Every copyrightable Creation, regardless of
whether copyright protection is sought or preserved by the Employer, shall be a
"work for hire" as defined in 12 U.S.C. ss. 101 and the Employer shall own all
rights in and to such matter throughout the world, without the payment of any
royalty or other consideration to Executive or anyone claiming through
Executive.

Executive shall execute and deliver to the Employer such formal transfers and
assignments and such other documents as the Employer may request to confirm and
protect the Employer's rights hereunder. Any idea, copyrightable matter or other
property relating to the Employer's business and disclosed by Executive or
discovered by the Employer prior to the first anniversary of the date of the
Executive's termination of employment (the "Termination Date") shall be deemed
to be governed hereby unless proved by Executive to have been first conceived
and made after the Termination Date.

3.7 CONFIDENTIALITY AND INSIDER TRADING AGREEMENTS. Concurrently with the
execution of this Agreement, Executive agrees to execute and deliver to the
Employer (i) the Executive Patent and Confidential Information Agreement and
(ii) the Statement of Policy regarding Insider Trading attached hereto as
Exhibits C and D, respectively.

3.8 REMEDIES. Executive agrees and understands that any breach of any of the
covenants 

                                      -7-
<PAGE>
 
or agreements set forth in this ARTICLE III of this Agreement will cause the
Employer irreparable harm for which there is no adequate remedy at law, and,
without limiting whatever other rights and remedies Employer may have under this
paragraph, Executive consents to the issuance of an injunction in favor of the
Employer enjoining the breach of any of the aforesaid covenants or agreements by
any court of competent jurisdiction. If any or all of the aforesaid covenants or
agreements are held to be unenforceable because of the scope or duration of such
covenant or agreement or the area covered thereby, the parties agree that the
court making such determination shall have the power to reduce or modify the
scope, duration and/or area of such covenant to the extent that allows the
maximum scope, duration and/or area permitted by applicable law.

                                   ARTICLE IV.

                                   TERMINATION

4.1 TERMINATION FOR CAUSE. Notwithstanding anything contained in this Agreement
to the contrary, the Employer shall have the right to terminate the employment
of the Executive upon the occurrence of any of the following events:

         (a)    The commission in the course of the Executive's employment by
                the Employer of any fraudulent act;

         (b)    Conviction of a felony (from which, through lapse of time or
                otherwise, no successful appeal shall have been made) whether or
                not committed in the course of his employment by the Employer;

         (c)    The willful refusal to carry out reasonable instructions of the
                Board; provided, however, that the Executive may only be
                discharged after he shall have been given 30 days written notice
                setting forth his alleged deficiencies and that he shall not,
                within such 30-day period, have ceased or otherwise cured the
                activity or activities or omission constituting the grounds for
                termination;

         (d)    The willful disclosure of any trade secrets or confidential
                corporate information of the Employer or BVI to persons not
                authorized to know same, unless such disclosure is required by
                any law or court order or similar process; and

         (e)    Inability of the Executive to perform the essential functions of
                his duties in accordance with the terms of this Agreement, with
                or without reasonable accommodation.

Where the employment of the Executive is terminated pursuant to this Article IV,
Section 4.1 of this Agreement, such termination shall be effective upon the
delivery of notice thereof to the 

                                      -8-
<PAGE>
 
Executive.

4.2 DEATH OF EXECUTIVE. In the event of Executive's death during the term of
this Agreement, this Agreement and the Employer's and the Executive's rights and
obligations under this Agreement shall terminate.

4.3 RESIGNATION OF EXECUTIVE. Executive may resign at any time for any reason
upon sixty (60) days advance written notice to the Chairman of the Board of
Directors provided that the Employer's obligations to the Executive, pursuant to
the terms of this Agreement, shall cease on the date the Executive's termination
is effective.

4.4. SURVIVING RIGHTS. Notwithstanding the termination of the Executive's
employment, the parties shall be required to carry out any provisions hereof
which contemplate performance subsequent to such termination; and such
termination shall not affect any liability or other obligation which shall have
accrued prior to such termination, including, but not limited to, any liability
for loss or damage on account of a prior default.

                                 INDEMNIFICATION

6.1 INDEMNIFICATION. Executive shall be entitled to indemnification and
advancement of expenses by reason of Executive's status with the Employer to the
fullest extent permitted under the laws of the State of Minnesota and the
Articles of Incorporation and bylaws of the Employer, and likewise, shall be
entitled to indemnification and advancement of expenses by reason of Executive's
status with Employer to the fullest extent permitted under the laws of the State
of Minnesota and Articles of Incorporation and bylaws of Employer. The Employer
represents to the Executive that as of the date hereof there is no provision of
the Articles of Incorporation or bylaws of the Employer that prohibits or limits
indemnification or advances of expenses or imposes conditions on indemnification
or advances of expenses in addition to the conditions set forth in Minnesota
law.

                                  ARTICLE VII.

Allocation of Annual Cash Incentive to be paid to Executive in accordance with
Section 2.2 of Executive's Employment Agreement to which this Exhibit A is
attached hereof.

                                                                   PERCENT
                                                                   ALLOCATION

Achievement of Personal Management by Objectives
("MBO") Goals as determined by the Employer                            20%

Employer Performance Goals:

         Operating Income                   40%
         Net Revenue                        40%                        80%
                                            ---                        ---

Total Allocation                                                      100%
                                                                      ===
For example, without limitation, assuming a Base Salary of $100,000 and the
Board determines that Executive has met all his MBO goals and the Employer has
met its Operating Income and Net Revenue goals, then Executive would receive
$20,000 ($100,000 X 20%). However, if the Board determines that the Executive
has met all his MBO goals, and the Employer has not met 100% of its Operating
Income and its Net Revenue goals, the Executive would receive $4,000 ($100,000 X
20% X 20%), only that incentive due related to MBO's. Likewise, if the Board
determines that the Executive has met only 75% of his MBO goals (and the
Employer has not met either of its Performance Goals) the Executive would
receive $3,000 (100,000 x 20% x 20% x75%).

                           CHANGE IN CONTROL AGREEMENT
                           ---------------------------

July 31, 1998

Mr. James F. Pfau
1788 Fremont Avenue South
Minneapolis, MN  55403

Dear Mr. Pfau:

You are presently the President of Jer-Neen Manufacturing Co., Inc., an
Affiliate of Bio-Vascular, Inc., a Minnesota corporation (the "Company"). The
Company considers the establishment and maintenance of a sound and vital
management to be essential to protecting and enhancing the best interests of the
Company and its shareholders. In this connection, the Company recognizes that,
as is the case with many publicly held corporations, the possibility of a Change
in Control may arise and that such possibility and the uncertainty and questions
which it may raise among management may result in the departure or distraction
of management personnel to the detriment of the Company and its shareholders.

Accordingly, the Board has determined that appropriate steps should be taken to
minimize the risk that Company management will depart prior to a Change in
Control, thereby leaving the Company without adequate management personnel
during such a critical period, and that appropriate steps also be taken to
reinforce and encourage the continued attention and dedication of members of the
Company's management to their assigned duties without distraction in
circumstances arising from the possibility of a Change in Control. In
particular, the Board believes it important, should the Company or its
shareholders receive a proposal for transfer of control, that you be able to
continue your management responsibilities without being influenced by the
uncertainties of your own personal situation.

The Board recognizes that continuance of your position with the Company involves
a substantial commitment to the Company in terms of your personal life and
professional career and the possibility of foregoing present and future career
opportunities, for which the Company receives substantial benefits. Therefore,
to induce you to remain in the employ of the Company, this Agreement, which has
been approved by the Board, sets forth the benefits which the Company agrees
will be provided to you in the event your employment with the Company is
terminated in connection with a Change in Control under the circumstances
described below.

The following terms will have the meaning set forth below unless the context
clearly requires otherwise. Terms defined elsewhere in this Agreement will have
the same meaning throughout this Agreement.

                                   ARTICLE I.
                                   DEFINITIONS

1.       "Affiliate" means (i) any corporation at least a majority of whose
         outstanding securities ordinarily having the right to vote at elections
         of directors is owned directly or indirectly by the Company or (ii) any
         other form of business entity in which the Company, by virtue of a
         direct or indirect ownership interest, has the right to elect a
         majority of the members of such entity's governing body.

2.       "Agreement" means this letter agreement as amended, extended or renewed
         from time to time in accordance with its terms.

3.       "Board" means the board of directors of the Company duly qualified and
         acting at the time in question. On and after the date of a Change in
         Control, any duty of the Board in connection with this Agreement is
         nondelegable and any attempt by the Board to delegate any such duty is
         ineffective.

4.       "Cause" means:

         a.    your gross misconduct;

         b.    your willful and continued failure to perform substantially your
               duties with the Company (other than any such failure (1)
               resulting from your Disability or incapacity due to bodily injury
               or physical or mental illness or (2) relating to changes in your
               duties after a Change in Control which constitute Good Reason)
               after a demand for substantial performance is delivered to you by
               the chair of the Board which specifically identifies the manner
               in which you have not substantially performed your duties and
               provides for a reasonable period of time within which you may
               take corrective actions; or

         c.    your conviction (including a plea of nolo contendere) of
               willfully engaging in illegal conduct constituting a felony or
               gross misdemeanor under federal or state law which is materially
               and demonstrably injurious to the Company or which impairs your
               ability to perform substantially your duties for the Company.

         An act or failure to act will be considered "gross" or "willful" for
         this purpose only if done, or omitted to be done, by you in bad faith
         and without reasonable belief that it was in, or not opposed to, the
         best interests of the Company. Any act, or failure to act, based upon
         authority given pursuant to a resolution duly adopted by the Company's
         board of directors (or a committee thereof) or based upon the advice of
         counsel for the Company will be conclusively presumed to be done, or
         omitted to be done, by you in good faith and in the best interests of
         the Company. It is also expressly understood that your attention to
         matters not directly related to the business of the Company will not
         provide a basis for termination for Cause so long as the Board did not
         expressly disapprove in writing of your engagement in such activities
         either before or within a reasonable period of time after the Board
         knew or could reasonably have known that you engaged in those
         activities. Notwithstanding the foregoing, you may not be terminated
         for Cause unless and until there has been delivered to 
<PAGE>
 
Mr. James F. Pfau
Page 3

         you a copy of a resolution duly adopted by the affirmative vote of not
         less than a majority of the entire membership of the Board at a meeting
         of the Board called and held for the purpose (after reasonable notice
         to you and an opportunity for you, together with your counsel, to be
         heard before the Board), finding that in the good faith opinion of the
         Board you were guilty of the conduct set forth above in clauses a., b.
         or c. of this definition and specifying the particulars thereof in
         detail.

5.       "Change in Control" means any of the following:

               more than 50 percent of the combined voting power of the

         objection to such nomination).

6.       "Code" means the Internal Revenue Code of 1986, as amended. Any
         reference to a specific provision of the Code includes a reference to
         such provision as it may be amended from time to time and to any

7.       "Company" means Bio-Vascular, Inc. and/or any Affiliate.

         information which you have a reasonable basis to consider confidential

         without regard to the manner in which you obtain access to that and any
         other proprietary information.

9.       "Date of Termination" following a Change in Control (or prior to a
         Change in Control if your termination was either a condition of the
         Change in Control or was at the request or insistence of any Person
         related to the Change in Control) means:

         a.    if your employment is to be terminated for Disability, 30 days

               given unless you and the Company otherwise expressly agree;

         c.    if your employment is to be terminated by the Company for any
               reason other than Cause, Disability, death or Retirement, the

               of, or after; receiving such Notice of Termination; or

         d.    if your employment is terminated by reason of death or

         Termination with respect thereto, you may notify the Company that a
         dispute exists concerning the termination, in which event the Date of
         Termination will be the date set either by mutual written agreement of
         the parties or by the judge or arbitrators in a proceeding as provided
         in Section 13 of this Agreement. During the pendency of any such
         dispute, you will continue to make yourself available to provide
         services to the Company and the Company will continue to pay you your
         full compensation and benefits in effect immediately prior to the date
         on which the Notice of Termination is given (without regard to any
         changes to such compensation or benefits which constitute Good Reason)
         and until the dispute is resolved in accordance with Section 13 of this
         Agreement. You will be entitled to retain the full amount of any such
         compensation and benefits without regard to the resolution of the
         dispute unless the judge or arbitrators decide(s) that your claim of a
         dispute was frivolous or advanced by you in bad faith.

10.      "Disability" means a disability as defined in the Company's long-term
         disability plan as in effect immediately prior to the Change in Control
         or; in the absence of such a plan, means permanent and total disability

               an executive of the Company as in effect immediately prior to the
               Change in Control which, in your reasonable judgment, is an
               adverse change (other than, if applicable, any such change
               directly attributable to the fact that the Company is no longer
               publicly owned) except in connection with the termination of your
               employment for Cause, Disability or Retirement or as a result of
               your death or by you other than for Good Reason;

         b.    a reduction by the Company in your base salary (or an adverse
               change in the form or timing of the payment thereof) as in effect

               which you (and/or your family) are eligible to participate at any
               time during the 90-day period immediately preceding the Change in
               Control (or Plans providing you (and/or your family) with at
               least substantially similar benefits) other than as a result of
               the normal expiration of any such Plan in accordance with its
               terms as in effect immediately prior to the 90-day period
               immediately preceding the time of the Change in Control, or the
               taking of any action, or the failure to act, by the Company which
               would adversely affect your (and/or your family's) continued
               eligibility to participate in any of such Plans on at least as
               favorable a basis to you (and/or your family) as is the case on
               the date of the Change in Control or which would materially
               reduce your (and/or your family's) benefits in the future under
               any of such Plans or deprive you (and/or your family) of any
               material benefit enjoyed by you (and/or your family) at the time
               of the Change in Control;

         d.    the Company's requiring you to be based more than 30 miles from

               Control, except for required travel on the Company's business,
               and then only to the extent substantially consistent with the
               business travel obligations which you undertook on behalf of the
               Company during the 90-day period immediately preceding the Change
               in Control (without regard to travel related to or in
               anticipation of the Change in Control);

         e.    the failure by the Company to obtain from any Successor the
               assent to this Agreement contemplated by Section 6 of this
               Agreement;

         f.    any purported termination by the Company of your employment which
               is not properly effected pursuant to a Notice of Termination and
               pursuant to any other requirements of this Agreement, and for
               purposes of this Agreement, no such purported termination will be
               effective;

         g.    any refusal by the Company to continue to allow you to attend to
               matters or engage in activities not directly related to the
               business of the Company which, at any time prior to the Change in
               Control, you were not expressly prohibited in writing by the
               Board from attending to or engaging in; or

         h.    your termination of your employment with the Company for any
               reason other than death, Disability or Retirement during the
               twelfth (12th) month following the month in which a Change in
               Control occurs.

13.      "Highest Monthly Compensation" means one-twelfth of the highest amount
         of your compensation for any 12 consecutive calendar-month period
         during the 36 consecutive calendar-month period prior to the month that
         includes the Date of Termination. For purposes of this definition,
         "compensation" means the amount reportable by the Company, for federal
         income tax purposes, as wages paid to you by the Company, increased by
         the amount of contributions made by the Company with respect to you

         in your income by reason of the operation of section 402(a)(8) or

         compensation deferred for any reason.

14.      "Notice of Termination" means a written notice given on or after the

         the Change in Control was either a condition of the Change in Control
         or was at the request or insistence of any Person related to the Change
         in Control) which indicates the specific termination provision in this
         Agreement pursuant to which the notice is given. Any purported
         termination by the Company or by you for Good Reason on or after the
         date of a Change in Control (or before the date of a Change in Control
         if your termination was either a condition of the Change in Control or
         was at the request or insistence of any Person related to the Change in
         Control) must be communicated by written Notice of Termination to be
         effective; provided, that your failure to provide Notice of Termination
         will not limit any of your rights under this Agreement except to the
         extent the Company demonstrates that it suffered material actual
         damages by reason of such failure.

15.      "Person" means any individual, corporation, partnership, group,
         association or other "person," as such term is used in section 14(d) of
         the Exchange Act, other than the Company, any Affiliate or any employee
         benefit plan(s) sponsored by the Company or an Affiliate.

         as a stock option, restricted stock plan or other equity-based plan),

         thrift, pension, profit sharing, medical, dental, disability, accident,
         life insurance, relocation, salary continuation, expense
         reimbursements, vacation, fringe benefits, office and support staff
         plan or policy) or any other plan, program, policy or agreement of the
         Company intended to benefit employees (and/or their families)
         generally, management employees (and/or their families) as a group or
         you (and/or your family) in particular.

         Company's outstanding securities ordinarily having the right to vote at
         the election of directors or, all or substantially all of its assets or

                                TERM OF AGREEMENT

This Agreement is effective immediately and will continue in effect until July
30, 1999; provided, however; that commencing on July 31, 1999 and each July 31st
thereafter, the term of this Agreement will automatically be extended for 12
additional months beyond the expiration date otherwise then in effect, unless at
least 90 calendar days prior to any such July 31, the Company or you has given
notice that this Agreement will not be extended; and, provided, further; that if
a Change in Control has occurred during the term of this Agreement, this
Agreement will continue in effect beyond the termination date then in effect for
a period of 12 months following the month during which the Change in Control
occurs or, if later, until the date on which the Company's obligations to you
arising under or in connection with this Agreement have been satisfied in full.

                                  ARTICLE III.
                           CHANGE IN CONTROL BENEFITS

1.       Benefits upon a Change in Control Termination. You will become entitled
         to the payments and benefits described in clauses (a) and (b) of this
         Article III., subject to the limitations described in clause (c) of
         this Article III., and to the benefit of the provisions described in
         clause (d), if and only if (i) your employment with the Company is
         terminated for any reason other than death, Cause, Disability or
         Retirement, or if you terminate your employment with the Company for
         Good Reason; and (ii) the termination occurs either within the period
         beginning on the date of a Change in Control and ending on the last day
         of the twelfth month that begins after the month during which the
         Change in Control occurs or prior to a Change in Control if your
         termination was either a condition of the Change in Control or was at
         the request or insistence of a Person related to the Change in Control.

         a.    Cash Payment. Within five business days following the Date of
               Termination or, if later, within five business days following the
               date of the Change in Control, the Company will make a lump-sum
               cash payment to you in an amount equal to the product of (i) your
               Highest Monthly Compensation multiplied by (ii) 36.

         b.    Welfare Plans. The Company will maintain in full force and
               effect, for the continued benefit of you and your dependents for
               a period terminating 36 months after the Date of Termination, all
               insured and self-insured employee welfare benefit Plans
               (including, without limitation, medical, life, dental, vision and
               disability plans) in which you were eligible to participate at
               any time during the 90-day period immediately preceding the
               Change in Control, provided that your continued participation is
               possible under the general terms and provisions of such Plans and
               any applicable funding media and without regard to any
               discretionary amendments to such Plans by the Company following
               the Change in Control (or prior to the Change in Control if
               amended as a condition or at the request or insistence of a
               Person (other than the Company) related to the Change in Control)
               and provided that you continue to pay an amount equal to your
               regular contribution under such 
<PAGE>
 
Mr. James Pfau
Page 9


               Plans for such participation (based upon your level of benefits
               and employment status most favorable to you at any time during
               the 90-day period immediately preceding the Change in Control).
               The continuation period under federal and state continuation
               laws, to the extent applicable, will begin to run from the date
               on which coverage pursuant to this clause (b) ends. If, at the
               end of the 36-month period, you have not previously received or
               are not then receiving equivalent benefits from a new employer
               (including coverage for any pre-existing conditions), the Company
               will arrange, at its sole cost and expense, to enable you to
               convert your and your dependents' coverage under such Plans to
               individual policies or programs upon the same terms as executives
               of the Company may apply for such conversions. In the event that
               your or your dependents' participation in any such Plan is
               barred, the Company, at its sole cost and expense, will arrange
               to have issued for the benefit of you and your dependents
               individual policies of insurance providing benefits substantially
               similar (on a federal, state and local income and employment
               after-tax basis) to those which you otherwise would have been
               entitled to receive under such Plans pursuant to this clause (b)
               or; if such insurance is not available at a reasonable cost to
               the Company, the Company will otherwise provide you and your
               dependents equivalent benefits (on a federal, state and local
               income and employment after-tax basis). You will not be required
               to pay any premiums or other charges in an amount greater than
               that which you would have paid in order to participate in such
               Plans.

         c.    Limitation on Payments and Benefits. Notwithstanding anything in
               this Agreement to the contrary, if any of the payments or
               benefits to be made or provided in connection with this
               Agreement, together with any other payments, benefits or awards
               which you have the right to receive from the Company, or any
               corporation which is a member of an "affiliated group" (as
               defined in section 1504(a) of the Code without regard to section
               1504(b) of the Code) of which the Company is a member
               ("Affiliate"), constitute an "excess parachute payment" (as
               defined in section 280G(b) of the Code), such payments, benefits
               or awards to be made or provided in connection with this
               Agreement, or any other agreement between you and the Company or
               its Affiliates, may be reduced, eliminated, modified or waived to
               the extent necessary to prevent all, or any portion, of such
               payments, benefits or awards from becoming "excess parachute
               payments" and therefore subject to the excise tax imposed under
               section 4999 of the Code. You will have the sole right and
               discretion to determine whether the payments, benefits or awards
               to be made or provided in connection with this Agreement, or any
               other agreement between you and the Company, should be reduced,
               whether or not such other agreement with the Company or an
               Affiliate expressly addresses the potential application of
               Sections 280G or 4999 of the Code (including, without limitation,
               that "payments" under such agreement be reduced). You will also
               have the right to designate the particular payments, benefits or
               awards that are to be reduced, eliminated, modified or waived;
               provided that no such adjustment will be made if it results in
               additional expense to the Company in excess of expenses the
               Company would have experienced if no

               adjustment had been made. The determination as to whether any
               such decrease in the payments or benefits is necessary must be
               made in good faith by legal counsel or a certified public
               accountant selected by you and reasonably acceptable to the
               Company, and such determination will be conclusive and binding
               upon you and the Company. The Company will pay or reimburse you
               on demand for the reasonable fees, costs and expenses of the
               counsel or accountant selected to make the determinations under
               this clause (c).

2.       Disposition. If, on or after the date of a Change in Control, an
         Affiliate is sold, merged, transferred or in any other manner or for
         any other reason ceases to be an Affiliate or all or any portion of the
         business or assets of an Affiliate are sold, transferred or otherwise
         disposed of and the acquiror is not the Company or an Affiliate (a
         "Disposition"), and you remain or become employed by the acquiror or an
         affiliate of the acquiror (as defined in this Agreement but
         substituting "acquiror" for "Company") in connection with the
         Disposition, you will be deemed to have terminated employment on the
         effective date of the Disposition for purposes of this section unless
         (a) the acquiror and its affiliates jointly and severally expressly
         assume and agree, in a manner that is enforceable by you, to perform
         the obligations of this Agreement to the same extent that the Company
         would be required to perform if the Disposition had not occurred and
         (b) the Successor guarantees, in a manner that is enforceable by you,
         payment and performance by the acquirer.

                                   ARTICLE IV.
                                 INDEMNIFICATION

Following a Change in Control, the Company will indemnify and advance expenses
to you to the full extent permitted by law and the Company's articles of
incorporation and bylaws for damages, costs and expenses (including, without
limitation, judgments, fines, penalties, settlements and reasonable fees and
expenses of your counsel) incurred in connection with all matters, events and
transactions relating to your service to or status with the Company or any other
corporation, employee benefit plan or other entity with whom you served at the
request of the Company.

                                   ARTICLE V.
                                 CONFIDENTIALITY

You will not use, other than in connection with your employment with the
Company, or disclose any Confidential Information to any person not employed by
the Company or not authorized by the Company to receive such Confidential
Information, without the prior written consent of the Company; and you will use
reasonable and prudent care to safeguard and protect and prevent the
unauthorized disclosure of Confidential Information. Nothing in this Agreement
will prevent you from using, disclosing or authorizing the disclosure of any
Confidential Information: (a) which is or hereafter becomes part of the public
domain or otherwise becomes generally available to the public through no fault
of yours; (b) to the extent and upon the terms and conditions that the Company
may have previously made the Confidential Information available to certain
persons; or (c) to the 
<PAGE>
 
Mr. James Pfau
Page 11


extent that you are required to disclose such Confidential Information by law or
judicial or administrative process.

                                   ARTICLE VI.
                                   SUCCESSORS

The Company will seek to have any Successor, by agreement in form and substance
satisfactory to you, assent to the fulfillment by the Company of the Company's
obligations under this Agreement. Failure of the Company to obtain such assent
at least three business days prior to the time a Person becomes a Successor (or
where the Company does not have at least three business days' advance notice
that a Person may become a Successor, within one business day after having
notice that such Person may become or has become a Successor) will constitute
Good Reason for termination by you of your employment. The date on which any
such succession becomes effective will be deemed the Date of Termination and
Notice of Termination will be deemed to have been given on that date. A
Successor has no rights, authority or power with respect to this Agreement prior
to a Change in Control.

                                  ARTICLE VII.
                                OTHER PROVISIONS

1.       Fees and Expenses. The Company, upon demand, will pay or reimburse you
         for all reasonable legal fees, court costs, experts' fees and related
         costs and expenses incurred by you in connection with any actual,
         threatened or contemplated litigation or legal, administrative,
         arbitration or other proceeding relating to this Agreement to which you
         are or reasonably expect to become a party, whether or not initiated by
         you, including, without limitation: (a) all such fees and expenses, if
         any, incurred in contesting or disputing any such termination; or (b)
         your seeking to obtain or enforce any right or benefit provided by this
         Agreement; provided, however; you will be required to repay (without
         interest) any such amounts to the Company to the extent that a court
         issues a final and non-appealable order setting forth the determination
         that the position taken by you was frivolous or advanced by you in bad
         faith.

2.       Binding Agreement. This Agreement inures to the benefit of, and is
         enforceable by, you, your personal and legal representatives,
         executors, administrators, successors, heirs, distributees, devisees
         and legatees. If you die while any amount would still be payable to you
         under this Agreement if you had continued to live, all such amounts,
         unless otherwise provided in this Agreement, will be paid in accordance
         with the terms of this Agreement to your devisee, legatee or other
         designee or; if there be no such designee, to your estate.

3.       No Mitigation. You will not be required to mitigate the amount of any
         payments or benefits the Company becomes obligated to make or provide
         to you in connection with this Agreement by seeking other employment or
         otherwise. The payments or benefits to be made or provided to you in
         connection with this Agreement may not be reduced, offset or 
<PAGE>
 
Mr. James Pfau
Page 12


         subject to recovery by the Company by any payments or benefits you may
         receive from other employment or otherwise.

4.       No Setoff. The Company has no right to setoff payments or benefits owed
         to you under this Agreement against amounts owed or claimed to be owed
         by you to the Company under this Agreement or otherwise.

5.       Taxes. All payments and benefits to be made or provided to you in
         connection with this Agreement will be subject to required withholding
         of federal, state and local income, excise and employment-related
         taxes.

6.       Notices. For the purposes of this Agreement, notices and all other
         communications provided for in, or required under, this Agreement must
         be in writing and will be deemed to have been duly given when
         personally delivered or when mailed by United States registered or
         certified mail, return receipt requested, postage prepaid and addressed
         to each party's respective address set forth on the first page of this
         Agreement (provided that all notices to the Company must be directed to
         the attention of the chair of the Board), or to such other address as
         either party may have furnished to the other in writing in accordance
         with these provisions, except that notice of change of address will be
         effective only upon receipt.

7.       Disputes.If you so elect, any dispute, controversy or claim arising
         under or in connection with this Agreement will be settled exclusively
         by binding arbitration administered by the American Arbitration
         Association in Minneapolis, Minnesota in accordance with the Commercial
         Arbitration Rules of the American Arbitration Association then in
         effect. Judgment may be entered on the arbitrator's award in any court
         having jurisdiction; provided, that you may seek specific performance
         of your right to receive payment or benefits until the Date of
         Termination during the pendency of any dispute or controversy arising
         under or in connection with this Agreement. The Company will be
         entitled to seek an injunction or restraining order in a court of
         competent jurisdiction (within or without the State of Minnesota) to
         enforce the provisions of Section 5 of this Agreement.

8.       Jurisdiction. Except as specifically provided otherwise in this
         Agreement, the parties agree that any action or proceeding arising
         under or in connection with this Agreement must be brought in a court
         of competent jurisdiction in the State of Minnesota, and hereby consent
         to the exclusive jurisdiction of said courts for this purpose and agree
         not to assert that such courts are an inconvenient forum.

9.       Related Agreements. To the extent that any provision of any other Plan
         or agreement between the Company and you limits, qualifies or is
         inconsistent with any provision of this Agreement, then for purposes of
         this Agreement, while such other Plan or agreement remains in force,
         the provision of this Agreement will control and such provision of such
         other Plan or agreement will be deemed to have been superseded, and to
         be of no force or effect, as if such other agreement had been formally
         amended to the extent necessary to accomplish such purpose. Nothing in
         this Agreement prevents or limits your continuing or 
<PAGE>
 
Mr. James Pfau
Page 13


         future participation in any Plan provided by the Company and for which
         you may qualify, and nothing in this Agreement limits or otherwise
         affects the rights you may have under any Plans or other agreements
         with the Company. Amounts which are vested benefits or which you are
         otherwise entitled to receive under any Plan or other agreement with
         the Company at or subsequent to the Date of Termination will be payable
         in accordance with such Plan or other agreement.

10.      No Employment or Service Contract. Nothing in this Agreement is
         intended to provide you with any right to continue in the employ of the
         Company for any period of specific duration or interfere with or
         otherwise restrict in any way your rights or the rights of the Company,
         which rights are hereby expressly reserved by each, to terminate your
         employment at any time for any reason or no reason whatsoever, with or
         without cause.

11.      Funding and Payment. Benefits payable under this Agreement will be paid
         only from the general assets of the Company. No person has any right to
         or interest in any specific assets of the Company by reason of this
         Agreement. To the extent benefits under this Agreement are not paid
         when due to any individual, he or she is a general unsecured creditor
         of the Company with respect to any amounts due. The Company with whom
         you were employed immediately before your Date of Termination has
         primary responsibility for benefits to which you or any other person
         are entitled pursuant to this Agreement but to the extent such Company
         is unable or unwilling to provide such benefits, the Company and each
         other Affiliate are jointly and severally responsible therefor to the
         extent permitted by applicable law. If you were simultaneously employed
         by more than one Company immediately before your Date of Termination,
         each such Company has primary responsibility for a portion of the
         benefits to which you or any other person are entitled pursuant to this
         Agreement that bears the same ratio to the total benefits to which you
         or such other person are entitled pursuant to this Agreement as your
         base pay from the Company immediately before your Date of Termination
         bears to your aggregate base pay from all such Companies.

12.      Survival.The respective obligations of, and benefits afforded to, the
         Company and you which by their express terms or clear intent survive
         termination of your employment with the Company or termination of this
         Agreement, as the case may be, including without limitation the
         provisions of Articles III, IV, V and VI and Sections 1, 4, 5, 6 and 7
         of Article VII of this Agreement, will survive termination of your
         employment with the Company or termination of this Agreement, as the
         case may be, and will remain in full force and effect according to
         their terms.

                                  ARTICLE VIII.
                                  MISCELLANEOUS

1.       Modification and Waiver. No provision of this Agreement may be
         modified, waived or discharged unless such modification, waiver or
         discharge is agreed to in a writing signed by you and the chair of the
         Board. No waiver by any party to this Agreement at any time of any
         breach by another party to this Agreement of, or of compliance with,
         any condition or 
<PAGE>
 
Mr. James Pfau
Page 14


         provision of this Agreement to be performed by such party will be
         deemed a waiver of similar or dissimilar provisions or conditions at
         the same or at any prior or subsequent time.

2.       Entire Agreement. No agreements or representations, oral or otherwise,
         express or implied, with respect to the subject matter to this
         Agreement have been made by any party which are not expressly set forth
         in this Agreement.

3.       GoverningLaw. This Agreement and the legal relations among the parties
         as to all matters, including, without limitation, matters of validity,
         interpretation, construction, performance and remedies, will be
         governed by and construed exclusively in accordance with the internal
         laws of the State of Minnesota (without regard to the conflict of laws
         principles of any jurisdiction).

4.       Headings. Headings are for purposes of convenience only and do not
         constitute a part of this Agreement.

5.       Further Acts. The parties to this Agreement agree to perform, or cause
         to be performed, such further acts and deeds and to execute and deliver
         or cause to be executed and delivered, such additional or supplemental
         documents or instruments as may be reasonably required by the other
         party to carry into effect the intent and purpose of this Agreement.

6.       Severability. The invalidity or unenforceability of all or any part of
         any provision of this Agreement will not affect the validity or
         enforceability of the remainder of such provision or of any other
         provision of this Agreement, which will remain in full force and
         effect.

7.       Counterparts. This Agreement may be executed in several counterparts,
         each of which will be deemed to be an original, but all of which
         together will constitute one and the same instrument.

FOR IMMEDIATE RELEASE


                       BIO-VASCULAR COMPLETES ACQUISITION
                       OF JER-NEEN MANUFACTURING CO., INC.

         ST. PAUL, MINN., AUGUST 3, 1998 - Bio-Vascular, Inc., (Nasdaq: BVAS)
announced today that it has completed the acquisition of Jer-Neen Manufacturing
Co., Inc., Lino Lakes, Minn., a value-added manufacturer of proprietary products
such as micro precision coils, wire forms and spring components used in
implantable defibrillation, interventional medicine and other surgical
applications within the medical device industry.
         Bio-Vascular issued 585,872 shares of common stock, together with cash
of $1.8 million, in exchange for all of the common stock of Jer-Neen, including
the assumption of Jer-Neen's liabilities as of the closing. Bio-Vascular paid an
additional $950,000 for a 10-year non-compete agreement covering the former
Jer-Neen shareholders.
         "The addition of Jer-Neen's medical components business broadens our
participation in the medical device industry and increases the company's
immediate and long-term revenue potential," said Karen Gilles, president and
chief executive officer of Bio-Vascular. "These benefits can be achieved without
diverting resources that are required for the development, manufacturing and
marketing of Bio-Vascular's current and future branded devices. The combination
achieves a strategic balance in market opportunities, consistent with the
corporate development objectives targeted by the company."
         Gilles said Jer-Neen is profitable and should have a neutral to
positive impact on Bio-Vascular's 1998 per-share results. For the nine months
ended July 31, 1998, Jer-Neen had net revenues of approximately $4.1 million
from its medical component business, which grew more than 30 percent over the
first three quarters of 1997. James F. Pfau will continue to manage Jer-Neen as
its president under a three-year employment agreement.
         Bio-Vascular, based in St. Paul, develops, manufactures and markets
proprietary specialty medical products for use in thoracic, cardiac, neuro,
ophthalmic and vascular surgery.
