Item 2.  Acquisition or Disposition of Assets.
- ----------------------------------------------

On February 9, 1998, I-Flow Corporation, a California corporation (the
"Registrant") entered into an Agreement and Plan of Merger (the "Agreement") by
and among the Registrant, I-Flow Subsidiary, Inc., a California corporation, and
a wholly owned subsidiary of the Registrant ("I-FlowSub"), InfuSystems II, Inc.,
a Michigan corporation ("InfuSystems"), Venture Medical, Inc., a Michigan
corporation ("VMI") and the shareholders of InfuSystems and VMI, contemplating
the merger of InfuSystems and VMI with and into I-FlowSub. Pursuant to the
Agreement, VMI and InfuSystems were merged with and into I-FlowSub (the
"Merger") effective as of February 11, 1998 (the "Effective Time").

In the Merger, all of the outstanding shares of common stock of VMI and
InfuSystems were exchanged for shares of common stock of the Registrant. The
aggregate number of shares of common stock of the Registrant issued in the
Merger to the shareholders of VMI and InfuSystems was 972,372 shares, valued at
approximately $2.9 million (subject to certain post-effective adjustments). As
contemplated by the Agreement, shares of common stock of the Registrant issued
in the Merger valued at $1.5 million (the "Escrowed Shares") were withheld by
the Registrant and were delivered to U.S. Trust Company of California, N.A., as
escrow agent, to be deposited in escrow. The Escrowed Shares, or cash equal to
the closing value of the Escrowed Shares, will be held for a period of two years
from the Effective Time during which time they will be subject to claims by the
Registrant and I-FlowSub to satisfy the obligations of InfuSystems, VMI and the
shareholders of InfuSystems and VMI under the Agreement (subject to the possible
earlier release of a portion of the Escrowed Shares in connection with
collection by I-FlowSub of certain accounts receivable). At each of the six
month, one year, eighteen month and two year anniversary of the closing, if the
value of the Registrant's common stock at such time is less than the value of
the Registrant's common stock as of the closing ($2.98 per share), then the
Registrant will be obligated to pay additional amounts as merger consideration.
The additional amounts, if any, will be calculated pursuant to the formula set
forth in Section 1.6(a)(ii) of the Agreement. At the Registrant's election, the
Registrant may pay such additional merger consideration, if any, by the issuance
of additional shares of the Registrant's common stock, in cash, or any
combination thereof.

In accordance with the terms of the Agreement, 59,395 shares of the Registrant's
common stock were issued to Amherst Capital Partners, L.L.C. ("Amherst"),
investment banker for InfuSystems and VMI, as payment of Amherst's fees and
expenses in connection with the Merger. In addition, in accordance with the
terms of the Agreement, the Registrant paid $50,000 to Cohen & Ellias, P.C.,
counsel for VMI and InfuSystems, as partial payment of the fees and expenses of
Cohen & Ellias, P.C. incurred in connection with the Merger.

The amount of consideration paid in the Merger was determined through
negotiations between the parties. The terms of the Merger were approved by the
Boards of Directors

                                       1

and shareholders of I-FlowSub, InfuSystems and VMI and by the Board of Directors
of the Registrant.

There is no material relationship between InfuSystems, VMI and the Registrant or
any of its affiliates, any director or officer of the Registrant, or any
associate of any such director or officer. Steven E. Watkins, former president
of VMI and InfuSystems, has been appointed president of I-FlowSub and has 
entered into an employment agreement with I-FlowSub.

               NOW, THEREFORE, in consideration of the premises and the
representations, warranties and agreements contained herein, the parties hereto
agree as follows:


                                    ARTICLE I

                            MERGER AND REORGANIZATION

               1.1 Merger. At the Effective Time (as defined in Section 1.4
below) and subject to and upon the terms and conditions of this Agreement,
California Law and Michigan Law, VMI and INFUSYSTEM shall be merged with and
into I-FLOWSUB, the separate corporate existences of VMI and INFUSYSTEM shall
cease and I-FLOWSUB shall continue as the surviving corporation. I-FLOWSUB as
the surviving corporation after the Merger is hereafter sometimes referred to as
the "SURVIVING CORPORATION." Upon consummation of the Merger, the corporate name
of I-FLOWSUB shall be changed to "Infusystem, Inc."

               1.2 Shareholder Approvals.

                   (a) I-FLOW, as the sole shareholder of I-FLOWSUB, has
approved and adopted this Agreement and the Merger contemplated hereby in
accordance with California Law and the Articles of Incorporation of I-FLOWSUB;
and

                   (b) VMI and INFUSYSTEM, acting through their respective
Boards of Directors, shall duly call, give notice of, convene and hold special
meetings of their shareholders (the "SPECIAL MEETINGS") to consider and vote
upon the approval and adoption of this Agreement and the Merger contemplated
hereby or prepare and distribute to their shareholders an action by written
consent of the shareholders approving and adopting this Agreement and the Merger
contemplated hereby (the "WRITTEN CONSENTS"), all in accordance with Michigan
Law and their respective Articles of Incorporation. VMI and INFUSYSTEM shall use
their best efforts to hold the Special Meetings or send the Written Consents as
soon as practicable after the date hereof.

               1.3 Closing. The closing of the Merger (the "CLOSING") will take
place at the offices of Gibson, Dunn & Crutcher LLP, 4 Park Plaza, Irvine,
California 92614, at 10:00 a.m. (local time) on January 30, 1998 or at such
other time or date as agreed to by the parties after the date on which the
shareholders of VMI and INFUSYSTEM shall have approved the Merger in accordance
with their respective Articles of Incorporation and Michigan Law but not later
than the third (3rd) business day following the satisfaction or waiver of all
applicable conditions to Closing; provided, however, that in no event shall the
Closing occur, except as agreed by the parties in writing, after February 6,
1998. The date of the Closing is referred to herein as the "CLOSING DATE."

               1.4 Consummation of Transactions. If, at the Closing, each of the
conditions in Article VII has been satisfied or any such condition is not
satisfied and the party whose obligation to close is subject to the satisfaction
of such condition elects to waive satisfaction of the condition, then the
transaction shall be consummated on such date and, then 



                                       2
<PAGE>   15

and thereupon, I-FLOW, I-FLOWSUB, VMI and INFUSYSTEM will each carry out the
procedures specified under the applicable provisions of California Law and
Michigan Law, to the end that the Merger shall become effective. The Merger
shall be consummated and become effective by filing the Agreement of Merger (the
"CALIFORNIA AGREEMENT OF MERGER") with the Secretary of State of the State of
California and the Certificate of Merger (the "MICHIGAN CERTIFICATE OF MERGER")
with the Secretary of State of the State of Michigan, in such form as required
by and executed in accordance with the relevant provisions of California Law and
Michigan Law, respectively. When used in this Agreement, "EFFECTIVE TIME" shall
mean the time at which the California Agreement of Merger and the Michigan
Certificate of Merger are so filed in accordance with California Law and
Michigan Law, respectively.

               1.5 Effect of the Merger.  At the Effective Time:

                   (a) VMI and INFUSYSTEM shall be merged with and into
I-FLOWSUB, with I-FLOWSUB as the Surviving Corporation;

                   (b) the separate existences of VMI and INFUSYSTEM shall
cease;

                   (c) the Articles of Incorporation of I-FLOWSUB shall be the
Articles of Incorporation of the Surviving Corporation (except that the name of
the Surviving Corporation shall be changed to "Infusystem, Inc.");

                   (d) the Bylaws of I-FLOWSUB shall be the Bylaws of the
Surviving Corporation;

                   (e) the directors and officers of I-FLOWSUB shall be the
respective directors and officers of the Surviving Corporation, each to serve
until his or her successor has been duly elected and qualified or otherwise as
provided by law;

                   (f) the Surviving Corporation's principal executive office
shall be located in the State of California; and

                   (g) the Merger, from and after the Effective Time, shall have
all the effects provided by California Law, Michigan Law and any other
applicable law.

               1.6 Merger Consideration and Effect on Capital Stock.

                   (a) Merger Consideration.

                       (i) The merger consideration ("MERGER CONSIDERATION")
shall be payable in shares of common stock of I-FLOW ("I-FLOW MERGER SHARES")
having an aggregate value of Two Million Eight Hundred Ninety-Seven Thousand Six
Hundred Sixty-Eight Dollars ($2,897,668), and be payable no later than ten (10)
calendar days after the Effective Time. The Merger Consideration shall be
divided into (A) the "VMI MERGER CONSIDERATION" which shall consist of I-FLOW
Merger Shares having an aggregate value of One Million Thirty-Seven Thousand Six
Hundred Fifty-Five Dollars ($1,037,655) (35.81% of 



                                       3
<PAGE>   16

the Merger Consideration) and (B) the "INFUSYSTEM MERGER CONSIDERATION" which
shall consist of I-FLOW Merger Shares having an aggregate value of One Million
Eight Hundred Sixty Thousand Thirteen Dollars ($1,860,013) (64.19% of the
Closing Merger Consideration).

                   The I-FLOW Merger Shares shall be valued based on the average
of the last sale price of I-FLOW's Common Stock on the Nasdaq Small Cap Market
for the period beginning fifteen (15) trading days and ending five (5) trading
days immediately preceding the Closing Date (the "CLOSING VALUE").

                       (ii) As additional consideration, I-FLOW agrees that:

                   (A) In the event the average closing price of I-FLOW's Common
Stock on the Nasdaq Small Cap Market for the twenty trading day period
immediately preceding the six month anniversary of the Closing (the "SIX MONTH
VALUE") is less than the Closing Value (subject to normal and customary
adjustment in the event of a stock split or similar event), I-FLOW will promptly
pay as additional Merger Consideration the "SIX MONTH SHORTFALL". For purposes
hereof, the Six Month Shortfall shall be the greater of zero or that dollar
amount calculated pursuant to the following calculation:

Step 1:        Multiply the aggregate number of I-Flow Merger Shares initially
               issued pursuant to this Agreement by twenty-five percent (25%)
               (the "PROPORTIONATE NUMBER OF MERGER SHARES").

Step 2:        Add the number of Escrowed Shares released to the Indemnified
               Parties to the number of Escrowed Shares (valued at the Closing
               Value) equal to the estimate of the amount of Buyer's Damages in
               connection with one or more outstanding and specified Buyer's
               Claims (the "NUMBER OF INDEMNIFICATION SHARES").

Step 3:        Add the aggregate number of I-Flow Merger Shares sold by the
               Shareholders to the Number of Indemnification Shares (the "NUMBER
               OF SUBTRACTED SHARES").

Step 4:        Subtract the Number of Subtracted Shares from the Proportionate
               Number of Merger Shares (the "NUMBER OF PRICE-GUARANTEED
               SHARES").

Step 5:        Subtract the Six Month Value from the Closing Value (the "PRICE
               DIFFERENTIAL").

Step 6:        Multiply the Price Differential by the Number of Price-Guaranteed
               Shares (the "SIX MONTH SHORTFALL").

                   (B) in the event the average closing price of I-FLOW's Common
Stock on the Nasdaq Small Cap Market for the twenty trading day period
immediately preceding the first anniversary of the Closing (the "ONE YEAR
VALUE") is less than the Closing Value (subject to normal and customary
adjustment in the event of a stock split or similar event), I-FLOW will promptly
pay as additional Merger Consideration the "ONE YEAR SHORTFALL".

                                       4
<PAGE>   17

               For purposes hereof, the One Year Shortfall shall be the greater
of zero or that dollar amount calculated pursuant to the following calculation:

Step 1:        Multiply the aggregate number of I-Flow Merger Shares initially
               issued pursuant to this Agreement by twenty-five percent (25%)
               (the "PROPORTIONATE NUMBER OF MERGER SHARES").

Step 2:        Add the number of Escrowed Shares released to the Indemnified
               Parties since the six month anniversary of the Closing to the
               number of Escrowed Shares (valued at the Closing Value) equal to
               the estimate of the amount of Buyer's Damages in connection with
               one or more outstanding and specified Buyer's Claims asserted
               since the six month anniversary of the Closing (the "NUMBER OF
               INDEMNIFICATION SHARES").

Step 3:        Add the aggregate number of I-Flow Merger Shares sold by the
               Shareholders since the six month anniversary of the Closing to
               the Number of Indemnification Shares (the "NUMBER OF SUBTRACTED
               SHARES").

Step 4:        Subtract the Number of Subtracted Shares from the Proportionate
               Number of Merger Shares (the "NUMBER OF PRICE-GUARANTEED
               SHARES").

Step 5:        Subtract the One Year Value from the Closing Value (the "PRICE
               DIFFERENTIAL").

Step 6:        Multiply the Price Differential by the Number of Price-Guaranteed
               Shares (the "ONE YEAR SHORTFALL").

               (C) in the event the average closing price of I-FLOW's Common
Stock on the Nasdaq Small Cap Market for the twenty trading day period
immediately preceding the eighteen month anniversary of the Closing (the
"EIGHTEEN MONTH VALUE") is less than the Closing Value (subject to normal and
customary adjustment in the event of a stock split or similar event), I-FLOW
will promptly pay as additional Merger Consideration the "EIGHTEEN MONTH
SHORTFALL". For purposes hereof, the Eighteen Month Shortfall shall be the
greater of zero or that dollar amount calculated pursuant to the following
calculation:

Step 1:        Multiply the aggregate number of I-Flow Merger Shares initially
               issued pursuant to this Agreement by twenty-five percent (25%)
               (the "Proportionate Number of Merger Shares").

Step 2:        Add the number of Escrowed Shares released to the Indemnified
               Parties since the one year anniversary of the Closing to the
               number of Escrowed Shares (valued at the Closing Value) equal to
               the estimate of the amount of Buyer's Damages in connection with
               one or more outstanding and specified Buyer's Claims asserted
               since the one year anniversary of the Closing (the "Number of
               Indemnification Shares").

                                       5
<PAGE>   18

Step 3:        Add the aggregate number of I-Flow Merger Shares sold by the
               Shareholders since the one year anniversary of the Closing to the
               Number of Indemnification Shares (the "Number of Subtracted
               Shares").

Step 4:        Subtract the Number of Subtracted Shares from the Proportionate
               Number of Merger Shares (the "Number of Price-Guaranteed
               Shares").

Step 5:        Subtract the Eighteen Month Value from the Closing Value (the
               "Price Differential").

Step 6:        Multiply the Price Differential by the Number of Price-Guaranteed
               Shares (the "Eighteen Month Shortfall").

               (D) in the event the average closing price of I-FLOW's Common
Stock on the Nasdaq Small Cap Market for the twenty trading day period
immediately preceding the two year anniversary of the Closing (the "TWO YEAR
VALUE") is less than the Closing Value (subject to normal and customary
adjustment in the event of a stock split or similar event), I-FLOW will promptly
pay as additional Merger Consideration the "TWO YEAR SHORTFALL". For purposes
hereof, the Two Year Shortfall shall be the greater of zero or that dollar
amount calculated pursuant to the following calculation:

Step 1:        Multiply the aggregate number of I-Flow Merger Shares initially
               issued pursuant to this Agreement by twenty-five percent (25%)
               (the "Proportionate Number of Merger Shares").

Step 2:        Add the number of Escrowed Shares released to the Indemnified
               Parties to the number of Escrowed Shares (valued at the Closing
               Value) equal to the estimate of the amount of Buyer's Damages in
               connection with one or more outstanding and specified Buyer's
               Claims asserted since the eighteen month anniversary of the
               Closing (the "Number of Indemnification Shares").

Step 3:        Add the aggregate number of I-Flow Merger Shares sold by the
               Shareholders since the eighteen month anniversary of the Closing
               to the Number of Indemnification Shares (the "Number of
               Subtracted Shares").

Step 4:        Subtract the Number of Subtracted Shares from the Proportionate
               Number of Merger Shares (the "Number of Price-Guaranteed
               Shares").

Step 5:        Subtract the Two Year Value from the Closing Value (the "Price
               Differential").

Step 6:        Multiply the Price Differential by the Number of Price-Guaranteed
               Shares (the "Two Year Shortfall").

                   The Six Month Shortfall, if any, shall be paid to the VMI
Shareholders and the INFUSYSTEMS Shareholders according to the percentages set
forth on 


                                       6
<PAGE>   19

Schedule 1.6(a) and the One Year Shortfall, Eighteen Month Shortfall and Two
Year Shortfall, if any, shall be paid according to the percentages set forth on
Schedule 1.6(b).

                   At its election, I-FLOW may pay the Six Month Shortfall, One
Year Shortfall, Eighteen Month Shortfall and Two Year Shortfall, if any, by the
issuance of additional shares of I-FLOW Common Stock valued at the Six Month
Value, One Year Value, Eighteen Month Value or Two Year Value, respectively, in
cash, or any combination of I-FLOW Common Stock and cash.

                   (b) Conversion. At the Effective Time:

                       (i) each holder of shares of common stock, par value
$0.01 per share, of VMI (the "VMI COMMON STOCK") which are outstanding
immediately prior to the Effective Time, other than any Dissenting Shares (as
defined in Section 1.6(g)), shall be entitled to receive in exchange for his VMI
Common Stock the number of shares of I-FLOW Merger Shares which, when valued at
the Closing Value, is equal to (x) the dollar amount of the VMI Merger
Consideration (y) divided by the number of shares of VMI Common Stock
outstanding immediately prior to the Effective Time and (z) multiplied by that
holder's number of shares of VMI Common Stock immediately prior to the Effective
Time; and

                       (ii) each holder of shares of common stock, no par value
per share, of INFUSYSTEM (the "INFUSYSTEM COMMON STOCK") which are outstanding
immediately prior to the Effective Time, other than any Dissenting Shares (as
defined in Section 1.6(g)), shall be entitled to receive in exchange for his
INFUSYSTEM Common Stock the number of shares of I-FLOW Merger Shares which, when
valued at the Closing Value, is equal to (x) the dollar amount of the INFUSYSTEM
Merger Consideration (y) divided by the number of shares of INFUSYSTEM Common
Stock outstanding immediately prior to the Effective Time and (z) multiplied by
that holder's number of shares of INFUSYSTEM Common Stock immediately prior to
the Effective Time.

                       Each holder of a certificate representing any VMI Common
Stock or INFUSYSTEM Common Stock (except for Dissenting Shares) shall after the
Effective Time cease to have any rights with respect to such VMI Common Stock or
INFUSYSTEM Common Stock, except the right to receive his pro rata share of the
Merger Consideration upon the surrender of such certificate in accordance with
this Section 1.6.

                   (c) Fractional Shares. No fractional shares of I-FLOW Common
Stock shall be issued in the Merger. In lieu of the issuance of any such
fractional shares, I-FLOW shall pay to each VMI Shareholder and INFUSYSTEM
Shareholder who otherwise would be entitled to receive fractional shares of
I-FLOW'S Common Stock an amount in cash (rounded to the nearest whole cent)
determined by multiplying (i) the Closing Value by (ii) the fraction of a share
of I-FLOW's Common Stock which such holder would otherwise be entitled to
receive pursuant to Section 1.6 (b).

                   (d) No Subsequent Transfers; Lost, Stolen or Destroyed
Certificates. After the Effective Time, there shall be no transfers on the stock
transfer books of the 

                                       7
<PAGE>   20

Surviving Corporation of shares of VMI Common Stock or INFUSYSTEM Common Stock
or Dissenting Shares that were registered as outstanding immediately prior to
the Effective Time. In the event that any registered certificate shall have been
lost, stolen or destroyed, the Surviving Corporation, upon the making of an
affidavit of that fact by the person claiming such certificate to be lost,
stolen or destroyed and an indemnification (subject to the following sentence),
shall make payment of the Shareholder's pro rata share of the Merger
Consideration for the shares of VMI Common Stock or INFUSYSTEM Common Stock
represented by such certificate in accordance with this Section 1.6 to the
persons legally entitled thereto. The Surviving Corporation, in its sole
discretion and as a condition precedent to the delivery of the Shareholder's pro
rata share of the Merger Consideration in exchange for the shares of VMI Common
Stock or INFUSYSTEM Common Stock represented by such certificate, may require
the owner of such lost, stolen or destroyed certificate to provide a bond or
other security in such sum as it reasonably may direct as indemnity against any
claim that may be made against the Surviving Corporation with respect to the
certificate alleged to have been so lost, stolen or destroyed.

                   (e) Tax Withholding. The right of any holder of shares of VMI
Common Stock or INFUSYSTEM Common Stock to receive the Merger Consideration as
provided herein shall be subject to and reduced by the amount of any required
tax withholding obligation. To the extent that I-FLOW withholds taxes from
payments to holders of shares of VMI Common Stock or INFUSYSTEM Common Stock,
I-FLOW shall provide each such holder with documentary evidence of any amounts
so withheld and information as to the basis therefor.

                   (f) I-FLOWSUB Capital Stock. Each share of common stock, par
value $0.01 per share, of I-FLOWSUB issued and outstanding immediately prior to
the Effective Time shall continue to represent one (1) share of issued and
outstanding common stock of the Surviving Corporation and shall not be affected
by the Merger.

                   (g) Dissenting Shares.

                       (i) Notwithstanding any provision of this Agreement to
the contrary, any shares of VMI Common Stock or INFUSYSTEM Common Stock held by
a holder who has exercised his dissenter's rights and demanded payment of the
fair value of such shares in accordance with Michigan Law and who, as of the
Effective Time, has not effectively withdrawn or lost such dissenter's rights
("DISSENTING SHARES"), shall not be converted into or represent a right to
receive the Merger Consideration pursuant to Section 1.6, but the holder thereof
shall only be entitled to such rights as are granted by Michigan Law.

                       (ii) Notwithstanding the provisions of Section 1.6(g)(i),
if any holder of shares of VMI Common Stock or INFUSYSTEM Common Stock who
exercises his dissenter's rights under Michigan Law shall effectively withdraw
or lose (through failure to perfect or otherwise) such rights, then, as of the
later of the Effective Time or the occurrence of such event, such holder's
shares shall automatically be converted into and represent only the right to
receive his pro rata share of the Merger Consideration applicable to such shares
as 


                                       8
<PAGE>   21

provided in this Section 1.6, without interest thereon, upon surrender of the
certificate or certificates representing such shares.

                       (iii) VMI and INFUSYSTEM shall give I-FLOW (A) prompt
notice of any exercise of any dissenter's rights by the holders of any shares of
VMI Common Stock or INFUSYSTEM Common Stock, withdrawals of such exercise, and
any other instruments served pursuant to Michigan Law and received by VMI and
INFUSYSTEM, and (B) the opportunity to direct all negotiations and proceedings
with respect to dissenter's rights under Michigan Law. VMI and INFUSYSTEM,
except with the prior written consent of I-FLOW, shall not voluntarily make any
agreement or payment with respect to any demand for appraisal of VMI Common
Stock or INFUSYSTEM Common Stock or offer to settle any such demands.

               1.7 Escrow Deposit. No later than ten (10) calendar days after
the Effective Time, I-FLOW shall deposit in escrow pursuant to Article IX
hereof, the number of shares of I-FLOW Common Stock constituting the Escrowed
Merger Consideration (as defined herein). Such shares shall be issued in the
name of the Escrow Agent (as defined below) "as Escrow Agent under that Escrow
Agreement dated [the Closing Date or otherwise with equivalent effect]". Such
shares shall be held for the purposes described in Article IX, Article X and the
Escrow Agreement (as hereinafter defined), and released to I-FLOW and/or the VMI
Shareholders and INFUSYSTEM Shareholders in accordance with the provisions of
Article IX, Article X and the Escrow Agreement.


                                   ARTICLE II
                      REPRESENTATIONS AND WARRANTIES OF VMI

               VMI and each VMI Shareholder jointly and severally represents and
warrants to I-FLOW and I-FLOWSUB as follows:

               2.1 Organization and Qualification. VMI is a corporation duly
organized, validly existing and in good standing under Michigan Law. VMI has the
requisite corporate power and authority to own, use or lease its properties and
to carry on its business as it is now being conducted and as it is now proposed
to be conducted. VMI has made available to I-FLOW and I-FLOWSUB a complete and
correct copy of its Articles of Incorporation and Bylaws, each as amended to
date, and VMI's Articles of Incorporation and Bylaws as so delivered are in full
force and effect. VMI is not in default in any material respect in the
performance, observation or fulfillment of any provision of its Articles of
Incorporation or Bylaws. For purposes of this Agreement, a "VMI MATERIAL ADVERSE
CHANGE" shall mean any event, circumstance, condition, development or occurrence
causing, resulting in or having (or with the passage of time could cause, result
in or have) a material adverse effect on the financial condition, business,
properties, prospects or results of operations of VMI taken as a whole.

<PAGE>   22

               2.2 Capitalization. The VMI Shareholders collectively own,
beneficially and of record, all of the issued and outstanding capital stock of
VMI. The authorized capital stock of VMI consists solely of 750,000 shares of
VMI Common Stock, $0.01 par value, of which 250,000 shares are issued and
outstanding. Such shares are owned of record as set forth on Schedule 2.2.
Except as set forth on Schedule 2.2, no agreement or other document grants or
imposes on any shares of the VMI Common Stock any right, preference, privilege
or restriction with respect to the transaction contemplated hereby (including,
without limitation, any rights of first refusal), other than the right to vote
as provided in Section 1.2 above and to dissent from the Merger as provided in
Section 1.6(g) above. All of the issued and outstanding shares of VMI's capital
stock have been duly authorized and validly issued and are fully paid,
nonassessable and free of preemptive rights created by any agreement to which
VMI is bound (except for VMI's Articles of Incorporation and Bylaws). There are
no options, warrants or other rights, commitments or agreements of any character
which call for the issuance of shares of capital stock or other securities of
VMI or any securities, instruments or rights convertible into or exchangeable
for shares of capital stock or other securities of VMI. At the Closing, the VMI
Shareholders listed on Schedule 2.2 will have good and valid title to, and sole
record and beneficial ownership of, such number of shares indicated on Schedule
2.2, free and clear of any claims, liens, pledges, options, security interests,
trusts, encumbrances or other rights or interests of any person.

               2.3 Voting Agreements. Neither VMI nor any VMI Shareholder is a
party or subject to any proxy, agreement or understanding and there is, to the
knowledge of VMI, no agreement or understanding between any other persons, that
affects or relates to the voting or giving of written consents with respect to
any VMI security or the voting by a VMI director.

               2.4 Authority Relative to this Agreement. Each VMI Shareholder
has the full right, power and authority to enter into this Agreement and to
perform his obligations hereunder. VMI has all requisite corporate power and
authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby (provided that the Merger is approved pursuant
to the provisions of Section 1.2 above and the applicable provisions of Michigan
Law). The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby on the part of VMI have been duly and validly
authorized by its Board of Directors, and no other corporate proceedings on the
part of VMI are necessary, as a matter of law or otherwise, to authorize this
Agreement or to consummate the transactions so contemplated (other than the
Merger, which is subject to the provisions of Section 1.2 and the applicable
provisions of California Law and Michigan Law). This Agreement has been duly and
validly executed and delivered by VMI and each VMI Shareholder and constitutes a
valid and binding agreement of VMI and each VMI Shareholder, enforceable against
VMI and each VMI Shareholder in accordance with its terms, except (a) as such
enforcement may be subject to bankruptcy, insolvency, reorganization, moratorium
or other similar laws now or hereafter in effect relating to creditors' rights,
and (b) as the remedy of specific performance and injunctive and other forms of
equitable relief may be subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

               2.5 Subsidiaries. VMI does not own, either directly or indirectly
any interest or investment (whether debt or equity) in any corporation,
partnership, joint venture, business, trust or other entity.

               2.6 Absence of Certain Changes. Except as set forth on Schedule
2.6, VMI, since December 31, 1996, has conducted its business only in, and has
not engaged in any transaction other than according to, the ordinary and usual
course of such business, and, since such date, there has not been (a) any VMI
Material Adverse Change; (b) any declaration, setting aside or payment of any
dividend or other distribution with respect to the capital stock of VMI; (c) any
material change by VMI in accounting principles, practices or methods; (d) any
labor dispute or difficulty which could result in any VMI Material Adverse
Change, and no such dispute or difficulty is now threatened; (e) any material
asset sold or disposed of (except inventory sold in the ordinary course of
business), any material asset mortgaged, pledged or subjected to any lien,
charge or other encumbrance; (f) any increase in the compensation payable or
which could become payable by VMI to its directors, officers, employees,
distributors, dealers or sales representatives; (g) any amendment of any
employee benefit plan; (h) any issuance, transfer, sale or pledge by VMI of any
shares of stock or other securities or of any commitments, options, rights or
privileges under which VMI is or may become obligated to issue any shares of
stock or other securities; (i) any indebtedness incurred by VMI, except such as
may have been incurred in the ordinary course of business and consistent with
past practice; (j) any loan made or agreed to be made by VMI, nor has VMI become
liable or agreed to become liable as a guarantor with respect to any loan; (k)
any waiver by VMI of any right or rights of material value or any payment,
direct or indirect, of any material debt, liability or other obligation; or (l)
any change in or amendment to the Articles of Incorporation or Bylaws of VMI.

               2.7 Financial Statements. The balance sheet of VMI as of December
31, 1996 and the related statements of operations and cash flow for the twelve
(12) month periods ended December 31, 1995 and December 31, 1996 (the "VMI
YEAR-END FINANCIAL STATEMENTS") are attached hereto as Schedule 2.7. The VMI
Year-End Financial Statements have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis throughout the
period indicated (except as may be noted therein), and present fairly the
financial position of VMI as of the end of such fiscal year and the results of
operations and cash flows for such fiscal year in conformity with generally
accepted accounting principles. The financial statements of VMI as of and for
the twelve (12) month period ended December 31, 1997 (also attached hereto as
Schedule 2.7) have been prepared in accordance with generally accepted
accounting principles applied on a basis consistent with the VMI Year-End
Financial Statements, and present fairly the financial position of VMI as of the
end of such twelve (12) month period and the results of operations and cash
flows for such twelve (12) month period in conformity with generally accepted
accounting principles, except that such financial statements may not contain all
footnotes required by generally accepted accounting principles and are subject
to normal recurring year-end adjustments. Such financial statements are
collectively referred to herein as the "VMI FINANCIAL STATEMENTS," and the
financial statements for the twelve (12) month period ended December 31, 1997
are referred to herein as the "VMI 1997 FINANCIAL STATEMENTS."

                   (a) Except as disclosed on Schedule 2.8 and to the extent
reserved against or reflected in the balance sheet of VMI included in the VMI
1997 Financial Statements, VMI did not have, at such date, any material
liabilities or obligations (contingent or otherwise) which were required by
generally accepted accounting principles, consistently applied, to be reflected
therein, and since that date VMI has not incurred any material liabilities or
obligations which, had they been incurred prior to December 31, 1997, would have
been required by such principles, so applied, to have been reflected in such
balance sheet, except such liabilities or obligations incurred in the ordinary
and usual course of business and consistent with past practice.

                   (b) VMI is not and will not be liable for prepayment or other
penalties in connection with the early retirement of any VMI indebtedness for
borrowed money.

               2.9 Consents and Approvals; No Violation. Except as disclosed on
Schedule 2.9, the execution and delivery of this Agreement by VMI, the
consummation of the transactions contemplated hereby or the performance by VMI
of its obligations hereunder will not:

                   (a) subject to the obtaining of any requisite approvals of
VMI's shareholders, conflict with any provision of VMI's Articles of
Incorporation or Bylaws;

                   (b) require any consent, approval, authorization or permit
of, or filing with or notification to, any governmental or regulatory authority,

or guaranteed payments) under any of the terms, conditions or provisions of any
material note, lease, mortgage, license, agreement, contract or other instrument
or obligation to which VMI is a party or by which VMI or any of its assets may
be bound;

                   (d) conflict with or violate the provisions of any order,
writ, injunction, judgment, decree, statute, rule or regulation applicable to
VMI; or

                   (e) result in the creation of any lien, charge or encumbrance
upon any shares of capital stock or assets of VMI under any agreement or
instrument to which VMI is bound.

               2.10 Broker's Commission or Finder's Fees. Except as disclosed in
Schedule 2.10, no person or entity has acted for VMI in connection with the
transactions provided for in this Agreement in a way which would entitle such
person to, and no person or entity is entitled 


                                       12
<PAGE>   25

to receive from VMI, any broker's commissions or finder's fees (or other similar
fees or commissions) in connection with this Agreement.

               2.11 Employment and Similar Agreements. Except as set forth on
Schedule 2.11:

                   (a) there are no employment, severance, bonus or
indemnification arrangements, agreements, understandings or plans between VMI
and any director, officer or employee thereof except those indemnification
provisions set forth in VMI's Articles of Incorporation and Bylaws;

                   (b) there are no agreements of the type described in Section
2.11(a) above (i) the benefits of which are contingent, or the terms of which
are altered, upon the occurrence of a transaction involving VMI of the nature of
any of the transactions contemplated by this Agreement, (ii) providing any term
of employment or compensation guaranty not terminable at will or (iii) providing
severance benefits or other benefits (which are conditioned upon a change in
control) after the termination of employment of such employee, regardless of the
reason for such termination of employment;

                   (c) there are no agreements or plans, any of the benefits of
which will be materially increased, or the vesting of benefits of which will be
materially accelerated, by the occurrence of any of the transactions
contemplated by this Agreement or the value of any of the benefits of which will
be calculated on the basis of any of the transactions contemplated by this
Agreement;

                   (d) subject to general principles related to wrongful
termination of employees, there are no officers or employees of VMI whose
employment is not terminable at the will of VMI;

                   (e) VMI is not obligated to compensate any consultants
pursuant to any agreement or arrangement which is material to VMI taken as a
whole; and

                   (f) VMI is not a party to, nor is bound by, any collective

True and complete copies of any agreements disclosed in Schedule 2.11 have been
delivered or made available to I-FLOW and I-FLOWSUB.

               2.12 Litigation. Except as set forth on Schedule 2.12, there is
no claim, action or proceeding pending or, to the knowledge of VMI, threatened
against or relating to VMI before any court or other competent governmental or
regulatory authority or body acting in an adjudicative capacity, or, to the
knowledge of VMI, any reasonable basis therefor. VMI, nor any officer, director
or employee of VMI, has been permanently or temporarily enjoined by any order,
judgment or decree of any court or any other governmental or regulatory
authority from engaging in or continuing any conduct or practice in connection
with the 


                                       13
<PAGE>   26

business, assets or properties of VMI nor, to the knowledge of VMI, is any
officer, director or employee of VMI under investigation by any governmental or
regulatory authority. There is not in existence any order, judgment or decree of
any court or other tribunal or other agency enjoining or requiring VMI to take
any action of any kind with respect to its business, assets or properties.

               2.13 Taxes.

                    (a) Except as set forth on Schedule 2.13(a), VMI has timely
filed all Returns (as defined below) required to be filed by it and all such
Returns are true, complete, and correct. All Taxes (as defined below) shown to
be payable on the Returns or subsequent assessments with respect thereto have
been paid in full on a timely basis, and no other Taxes are payable by VMI with
respect to items or periods covered by such Returns (whether or not shown on or
reportable on such Returns) or with respect to any period prior to the date of
this Agreement. VMI has withheld and paid over all Taxes required to have been
held and paid over, and complied with, all information reporting and backup
withholding requirements, including maintenance of required records with respect
thereto, in connection with amounts paid or owing to any employee, creditor,
independent contractor, or other third party. There are no liens on any of the
assets of VMI with respect to Taxes, other than liens for Taxes not yet due and
payable or for Taxes that VMI is contesting in good faith through appropriate
proceedings and for which appropriate reserves have been established.

                    (b) The amount of VMI's liability for unpaid Taxes for all
periods ending on or prior to the date of this Agreement do not, in the
aggregate, exceed the amount of the current liability accruals reflected on the
VMI Financial Statements for Taxes (excluding reserves for deferred Taxes and
excluding liability for unpaid Taxes incurred by VMI in the ordinary course of
business since the date of the VMI 1997 Financial Statements) with respect to
VMI as of the date of this Agreement, and the amount of VMI's liability for
unpaid Taxes for all periods on or prior to the Closing Date shall not, in the
aggregate, exceed the amount of the current liability accruals reflected on the
VMI Financial Statements for Taxes (excluding reserves for deferred Taxes and
excluding liability for unpaid Taxes incurred by VMI in the ordinary course of

VMI as of the Closing Date.

                    (c) Except as set forth on Schedule 2.13(c), the Returns of
VMI have never been audited by a government or taxing authority, nor is any such
audit in process, pending, or threatened (either in writing or verbally,
formally or informally) or are expected to be asserted with respect to Taxes of
VMI, and VMI has not received notice (either in writing or verbally, formally or
informally) or expects to receive notice that it has not filed a Return or paid
Taxes required to be filed or paid by it. VMI is neither a party to any action

sharing agreement and has not assumed the tax liability of any other person

                    (g) There is no plan or intention ("PLAN") on the part of
the VMI Shareholders to engage in a sale, exchange, transfer, pledge,
disposition, or any other transaction which results in a reduction in the risk
of ownership or a direct or indirect disposition (a "SALE") of the VMI Closing
Merger Consideration and the VMI Escrowed Merger Consideration that would reduce
ownership by the VMI Shareholders of such consideration to a number of shares
having a value as of the Effective Time of the Merger of less than fifty percent
(50%) of the aggregate fair market value, immediately prior to the Merger, of
all outstanding shares of VMI Common Stock. For purposes of this representation,
shares of VMI Common Stock exchanged for cash in lieu of fractional shares and
disposed of through the exercise of dissenters' rights shall be considered
shares of VMI Common Stock outstanding prior to the Merger.

               2.14 ERISA Plans. Each employee pension benefit plan, program,
agreement or arrangement ("VMI PLAN") maintained or contributed to by VMI which
is subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), if any, is set forth on Schedule 2.14 and such VMI Plans conform in
all material respects to, and their administration is in conformity in all
material respects with, all applicable federal laws; no

accepted accounting principles; there is not in the aggregate any accumulated
funding deficiency with respect to such VMI Plans; and the current value of
accrued benefits of each such VMI Plan does not exceed the current value of such
VMI Plan's assets. VMI has delivered or made available to I-FLOW and I-FLOWSUB

vehicles, policies or contracts and any related summary plan descriptions with
respect to each VMI Plan; (ii) the most recent determination letters received

of:

                    (a) Each material customer contract, whether written or
oral, between VMI and any party to whom VMI provides goods or services; and

                    (b) Each contract, whether written or oral, between VMI and
any party to whom VMI is obligated to make any payments.

        The contracts and agreements which are required to be identified in

                        (i) Each of the VMI Contracts is a valid, binding and
enforceable agreement of VMI and, to the knowledge of VMI, the other parties
thereto and, to the knowledge of VMI, will, subject to the satisfaction of the
conditions in Article VII, continue to be valid, binding and enforceable
immediately after the Closing, except (a) as such enforcement may be subject to
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to creditors' rights, and (b) as the remedy of
specific performance and injunctive and other forms of equitable relief may be
subject to equitable defenses and to the discretion of the court before which
any proceeding therefor may be brought;

                        (ii) VMI has no reason to believe that VMI will not be
able to fulfill in all material respects all of its obligations under the VMI
Contracts which remain to be performed;

                                       16
<PAGE>   29

                        (iii) To the knowledge of VMI, there has not occurred
any material default (or event which upon provision of notice or lapse of time
or both would become such a default) under any of the VMI Contracts on the part
of VMI; and

                        (iv) The VMI Contracts listed on Schedule 2.15 are all
of the agreements, promissory notes, contracts and instruments (except
employment agreements which are set forth on Schedule 2.11) that are material to
VMI or its business.

               2.16 Patents, Marks, Trade Names, Copyrights and Registrations.

                    (a) VMI has sufficient right, title and interest in all
Intellectual Property (as defined below) necessary for the business of VMI as

not alter or impair in an adverse manner such Intellectual Property rights.

                    (b) "INTELLECTUAL PROPERTY" includes United States and
foreign inventions, invention disclosures, patents, inventors' certificates,
utility models, trademarks, service marks, trade names, copyrights, mask work

action and remedies therefor.

                    (c) VMI is not in default under any material agreement
pursuant to which it is licensing Intellectual Property of a third party or
granting licenses to its own Intellectual Property. VMI has not notified any
other party of an alleged default of any such agreement. VMI has not received
any communications alleging that VMI has violated in any material respect any
other person's Intellectual Property rights or has engaged in unfair competition
against such person.

                    (d) VMI does not now infringe or misappropriate any third
party's Intellectual Property rights and does not have any material liability
for any past infringement or misappropriation. No material dispute or

with regard to any third party Intellectual Property right, including any
allegation of Intellectual Property infringement or misappropriation or of any
breach or default of an Intellectual Property license or similar agreement.

               2.17 Properties, Liens. Except as set forth on Schedule 2.17, VMI
owns, free and clear of any liens, claims, charges, options or other
encumbrances, all of its tangible and intangible property, real and personal,
whether or not reflected in the VMI 1997 Financial Statements (except property
sold or disposed of in the ordinary course of business since August 31, 1997)
and all such property acquired since such date that is necessary to conduct its
business as it is now being conducted, and there has not been any violation of
any law, regulation or ordinance (including without limitation laws, regulations
and ordinances relating to health, fire, safety, zoning, environmental,
building, city planning or similar issues) relating to its properties or its
business which could result in a VMI Material Adverse Change. All material
plants, structures and equipment owned or leased by VMI and material to the
operation of its business are in satisfactory condition and repair for the
requirements of its 

                                       17
<PAGE>   30

business as now being conducted. There are no proceedings affecting any of such
properties pending or, to the knowledge of VMI, threatened which may reasonably
be expected to curtail, materially and adversely, the use of such property for
the purpose for which it was acquired or the purpose for which it is now used.

               2.18 Real Property. VMI does not own any real property. Schedule
2.18 lists each lease of real property under which VMI is a lessee, lessor,
sublessee or sublessor, as so designated therein (the "VMI REAL PROPERTY").
Except as indicated in Schedule 2.18, all material leases, easements and other
real property interests held by VMI are valid and enforceable and VMI is not in
material default thereunder.

               2.19 Compliance with Applicable Laws. Except as disclosed in

and authorizations necessary for the lawful conduct of its respective
businesses, as then and now conducted and (b) such businesses have not been and
are not being, and VMI has not received any notice from any authority or person
that such businesses have been or are being, conducted in violation of any law,
ordinance or regulation, including without limitation any law, ordinance or
regulation relating to (i) the protection of the environment, (ii) the provision
of medical supplies and services, or (iii) occupational health and safety.

               2.20 Insurance. Schedule 2.20 sets forth a true and correct list
of all insurance policies of any nature whatsoever maintained by VMI pertaining
to the business of VMI. VMI maintains, with responsible insurance carriers,
property, auto liability, professional liability, workers' compensation and
general liability insurance. Such policies and binders are and will be in full
force and effect through the Effective Time and, except as otherwise set forth
on Schedule 2.20, such policies, or other policies covering the same risks, have
been in full force and effect, without gaps, continuously for the past five (5)
years. Copies of all such policies have been made available to I-FLOW for its
inspection. VMI is not in default under any of such policies or binders, and VMI
has not failed to give any notice or to present any claim on behalf of VMI, that
could result in a claim in excess of $5,000, under any such policy or binder in
a due and timely fashion. Except as set forth on Schedule 2.20, VMI is not aware
of any facts concerning VMI or its businesses, operations, assets and
liabilities, contingent or otherwise, upon which an insurer might be justified
in reducing coverage or increasing premiums on existing policies or binders.

formerly owned or operated by VMI, alleging liability under any Environmental
Law;

it is now proposed to be conducted. INFUSYSTEM has made available to I-FLOW and
I-FLOWSUB a complete and correct copy of its Articles of Incorporation and
Bylaws, each as amended to date, and INFUSYSTEM's Articles of Incorporation and
Bylaws as so delivered are in full force and effect. INFUSYSTEM is not in
default in any material respect in the performance, observation or fulfillment
of any provision of its Articles of Incorporation or Bylaws. For purposes of
this Agreement, an "INFUSYSTEM MATERIAL ADVERSE CHANGE" shall mean any event,
circumstance, condition, development or occurrence causing, resulting in or
having (or with the passage of time could cause, result in or have) a material
adverse effect on the financial condition, business, properties, prospects or
results of operations of INFUSYSTEM taken as a whole.

               3.2 Capitalization. The INFUSYSTEM Shareholders collectively own,
beneficially and of record, all of the issued and outstanding capital stock of
INFUSYSTEM. The authorized capital stock of INFUSYSTEM consists solely of 60,000
shares of INFUSYSTEM Common Stock, no par value, of which 6,000 shares are
issued and 

                                       23

outstanding. Such shares are owned of record as set forth on Schedule 3.2.
Except as set forth on Schedule 3.2, no agreement or other document grants or
imposes on any shares of the INFUSYSTEM Common Stock any right, preference,
privilege or restriction with respect to the transaction contemplated hereby
(including, without limitation, any rights of first refusal), other than the
right to vote as provided in Section 1.2 above and to dissent from the Merger as
provided in Section 1.6(g) above. All of the issued and outstanding shares of
INFUSYSTEM's capital stock have been duly authorized and validly issued and are
fully paid, nonassessable and free of preemptive rights created by any agreement
to which INFUSYSTEM is bound (except for INFUSYSTEM's Articles of Incorporation
and Bylaws). There are no options, warrants or other rights, commitments or
agreements of any character which call for the issuance of shares of capital
stock or other securities of INFUSYSTEM or any securities, instruments or rights
convertible into or exchangeable for shares of capital stock or other securities
of INFUSYSTEM. At the Closing, the INFUSYSTEM Shareholders listed on Schedule
3.2 will have good and valid title to, and sole record and beneficial ownership
of, such number of shares indicated on Schedule 3.2, free and clear of any
claims, liens, pledges, options, security interests, trusts, encumbrances or
other rights or interests of any person.

               3.3 Voting Agreements. Neither INFUSYSTEM nor any INFUSYSTEM
Shareholder is a party or subject to any proxy, agreement or understanding and
there is, to the knowledge of INFUSYSTEM, no agreement or understanding between
any other persons, that affects or relates to the voting or giving of written
consents with respect to any INFUSYSTEM security or the voting by an INFUSYSTEM
director.

               3.4 Authority Relative to this Agreement. Each INFUSYSTEM
Shareholder has the full right, power and authority to enter in this Agreement
and to perform his obligations hereunder. INFUSYSTEM has all requisite corporate
power and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby (provided that the Merger is approved pursuant
to the provisions of Section 1.2 above and the applicable provisions of Michigan
Law). The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby on the part of INFUSYSTEM have been duly and
validly authorized by its Board of Directors, and no other corporate proceedings
on the part of INFUSYSTEM are necessary, as a matter of law or otherwise, to
authorize this Agreement or to consummate the transactions so contemplated
(other than the Merger, which is subject to the provisions of Section 1.2 and
the applicable provisions of California Law and Michigan Law). This Agreement
has been duly and validly executed and delivered by INFUSYSTEM and constitutes a
valid and binding agreement of INFUSYSTEM and each INFUSYSTEM Shareholder
enforceable against INFUSYSTEM and each INFUSYSTEM Shareholder in accordance
with its terms, except (a) as such enforcement may be subject to bankruptcy,
insolvency, reorganization, moratorium or other similar laws now or hereafter in
effect relating to creditors' rights, and (b) as the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought.

respect to its business, assets or properties.

               3.13 Taxes.

                    (a) Except as set forth on Schedule 3.13(a), INFUSYSTEM has
timely filed all Returns (as defined below) required to be filed by it and all
such Returns are true, complete, and correct. All Taxes (as defined below) shown
to be payable on the Returns or subsequent assessments with respect thereto have
been paid in full on a timely basis, and no other Taxes are payable by
INFUSYSTEM with respect to items or periods covered by such Returns (whether or
not shown on or reportable on such Returns) or with respect to any period prior
to the date of this Agreement. INFUSYSTEM has withheld and paid over all Taxes
required to have been held and paid over, and complied with all information
reporting and backup withholding requirements, including maintenance of required
records with respect thereto, in connection with amounts paid or owing to any
employee, creditor, independent contractor, or other third party. There are no
liens on any of the assets of INFUSYSTEM with respect to Taxes, other than liens

                    (b) The amount of INFUSYSTEM's liability for unpaid Taxes
for all periods ending on or prior to the date of the Agreement do not, in the

INFUSYSTEM Financial Statements for Taxes (excluding reserves for deferred Taxes
and excluding liability for unpaid Taxes incurred by INFUSYSTEM in the ordinary
course of business since the date of the INFUSYSTEM 1997 Financial Statements)
with respect to INFUSYSTEM as of the date of this Agreement, and the amount of
INFUSYSTEM's liability for unpaid Taxes for all periods on or prior to the
Closing Date shall not, in the aggregate, exceed the amount of the current
liability accruals reflected on the INFUSYSTEM Financial Statements for Taxes
(excluding reserves for deferred Taxes and excluding liability for unpaid Taxes
incurred by INFUSYSTEM in the ordinary course of business since the date of the
INFUSYSTEM 1997 Financial Statements) with respect to INFUSYSTEM as of the
Closing Date.

                    (c) Except as set forth on Schedule 3.13(c), the Returns of
INFUSYSTEM have never been audited by a government or taxing authority, nor is
any such 


                                       28

audit in process, pending, or threatened (either in writing or verbally,
formally or informally) or are expected to be asserted with respect to Taxes of
INFUSYSTEM, and INFUSYSTEM has not received notice (either in writing or
verbally, formally or informally) or expects to receive notice that it has not
filed a Return or paid Taxes required to be filed or paid by it. INFUSYSTEM is
neither a party to any action or proceeding for assessment or collection of
Taxes, nor has such event been asserted or threatened (either in writing or
verbally, formally or informally) against INFUSYSTEM or any of its assets. No
waiver or extension of any statute of limitations is in effect with respect to
Taxes or Tax Returns of INFUSYSTEM. INFUSYSTEM has disclosed on its federal
income tax returns all positions taken therein that could give rise to a
substantial understatement penalty within the meaning of Section 6662 of the
Code.

                    (d) INFUSYSTEM is not (nor has it ever been) a party to any
tax sharing agreement and has not assumed the tax liability of any other person
under contract.

                    (e) For purposes of this Section 3.13, (i) the term "TAXES"
shall mean all taxes, however denominated, including any interest, penalties, or
other additions to tax that may become payable in respect thereof, imposed by
any federal, territorial, state, local, or foreign government or any agency or

foregoing, which INFUSYSTEM is required to pay, withhold, or collect, and (ii)
the term "RETURN" shall mean all reports, estimates, declarations of estimated
tax, information statements and returns relating to, or required to be filed in
connection with, any Taxes, including information returns or reports with
respect to backup withholding and other payments to third parties.

                    (f) Other than dispositions made in the ordinary course of
business, INFUSYSTEM has not disposed of any of its assets (including any
distribution of assets with respect to, or in redemption of, its stock) during
the two year period ending on the date of this Agreement.

                    (g) There is no plan or intention ("PLAN") on the part of 
the INFUSYSTEM Shareholders to engage in a sale, exchange, transfer, pledge,
disposition, or any other transaction which results in a reduction in the risk
of ownership or a direct or indirect disposition (a "SALE") of the INFUSYSTEM
Closing Merger Consideration and the INFUSYSTEM Escrowed Merger Consideration
that would reduce ownership by the INFUSYSTEM Shareholders of such consideration
to a number of shares having a value as of the Effective Time of the Merger of
less than fifty percent (50%) of the aggregate fair market value, immediately
prior to the Merger, of all outstanding shares of INFUSYSTEM Common


                                       29
<PAGE>   42

Stock. For purposes of this representation, shares of INFUSYSTEM Common Stock
exchanged for cash in lieu of fractional shares or disposed of through the
exercise of dissenters' rights shall be considered shares of INFUSYSTEM Common
Stock outstanding prior to the Merger.

INFUSYSTEM Financial Statements in accordance with generally accepted accounting
principles; there is not in the aggregate any accumulated funding deficiency
with respect to such INFUSYSTEM Plans; and the current value of accrued benefits
of each such INFUSYSTEM Plan does not exceed the current value of such
INFUSYSTEM Plan's assets. INFUSYSTEM has delivered or made available to I-FLOW

related trusts or funding vehicles, policies or contracts and any related

services; and

                    (b) Each contract, whether written or oral, between

                        (i) Each of the INFUSYSTEM Contracts is a valid, binding
and enforceable agreement of INFUSYSTEM and, to the knowledge of INFUSYSTEM, the
other parties thereto and, to the knowledge of INFUSYSTEM, will, subject to the
satisfaction of the conditions in Article VII, continue to be valid, binding and
enforceable immediately after the Closing, except (a) as such enforcement may be
subject to bankruptcy, insolvency, reorganization, moratorium or other similar
laws now or hereafter in effect relating to creditors' rights, and (b) as the
remedy of specific performance and injunctive and other forms of equitable
relief may be subject to equitable defenses and to the discretion of the court

of time or both would become such a default) under any of the INFUSYSTEM
Contracts on the part of INFUSYSTEM; and

                        (iv) The INFUSYSTEM Contracts listed on Schedule 3.15
are all of the agreements, promissory notes, contracts and instruments (except
employment agreements which are set forth on Schedule 3.11) that are material to
INFUSYSTEM or its business.

               3.16 Patents, Marks, Trade Names, Copyrights and Registrations.

                    (a) INFUSYSTEM has sufficient right, title and interest in
all Intellectual Property (as defined below) necessary for the business of

                    (c) INFUSYSTEM is not in default under any material
agreement pursuant to which it is licensing Intellectual Property of a third

infringement or misappropriation. No material dispute or disagreement involving

whether or not reflected in the INFUSYSTEM 1997 Financial Statements (except
property sold or disposed of in the ordinary course of business since August 31,
1997) and all such property acquired since such date that is necessary to
conduct its business as it is now being conducted, and there has not been any
violation of any law, regulation or ordinance (including without limitation

properties or its business which could result in an INFUSYSTEM Material Adverse
Change. All material plants, structures and equipment owned or leased by
INFUSYSTEM and material to the operation of its business are in satisfactory
condition and repair for the requirements of its business as now being
conducted. There are no proceedings affecting any of such properties pending or,
to the knowledge of INFUSYSTEM, threatened which may reasonably be expected to

person that such businesses have been or are being, conducted in violation of
any law, ordinance or regulation, including without limitation any law,
ordinance or regulation relating to (i) the protection of the environment, (ii)

validly executed and delivered by I-FLOW and I-FLOWSUB and constitutes a valid
and binding agreement of both I-FLOW and I-FLOWSUB, enforceable against each of
them in accordance with its terms, except (a) as such enforcement may be subject
to bankruptcy, insolvency, reorganization, moratorium or other similar laws now
or hereafter in effect relating to creditors' rights, and (b) as the remedy of
specific performance and injunctive and other forms of equitable relief may be
subject to equitable defenses and to the discretion of the court before which

               4.3 Broker's Commission or Finder's Fees. No person or entity has
acted for I-FLOW or I-FLOWSUB in connection with the transactions provided for
in this Agreement in a way which would entitle such person to any broker's

connection with this Agreement or the transactions contemplated hereby.

               4.4 I-FLOW Shares. Upon consummation of the transactions
contemplated by this Agreement, the I-FLOW Shares issued as the Merger

issued, fully paid and non-assessable. Upon delivery of their shares of VMI
Common Stock or INFUSYSTEM Common Stock, the VMI Shareholders and the INFUSYSTEM
Shareholders receiving the Closing Merger Consideration 


                                       38

all material respects with the applicable requirements of the 1933 Act and the
1934 Act.

               4.6 Tax-Free Reorganization. Neither I-FLOW nor I-FLOWSUB has any
reason to believe that the Merger will not qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Code.

               4.7 Full Disclosure. All instruments, agreements and other
documents delivered or to be delivered, or made available, to VMI and INFUSYSTEM
pursuant to this Agreement are complete and correct in all material respects. No

will omit to state a material fact required to be stated herein or therein
necessary to make the statements on behalf of I-FLOW and I-FLOWSUB in this
Article IV, in the light of the circumstances in which they are made, not

than as reflected in the preliminary operating results previously provided,
there has not been any change in I-FLOW's business, assets, financial condition

<PAGE>   58

result in a VMI Material Adverse Change or an INFUSYSTEM Material Adverse Change

Amherst Capital Partners, L.L.C. ("AMHERST"), neither VMI nor INFUSYSTEM shall

in effect prior to the Effective Time. In case at any time after the Effective
Time any further action is necessary or desirable to carry out the purposes of
this Agreement or to vest the Surviving Corporation with full title to all
properties, assets, rights, approvals, immunities and franchises of either of
I-FLOWSUB or VMI or INFUSYSTEM, the proper officers and directors of each
corporation which is a party to this Agreement shall take all such necessary
action.

               6.9 Tax Treatment of Merger. Each party agrees to report the
Merger on all tax returns and other filings as a tax-free reorganization under

party, there is not "substantial authority," as defined in Section 6662 of the
Code, to support such a position.

               6.10 Tax-Free Reorganization. From and after the Effective Time,
neither VMI, INFUSYSTEMS, I-FLOW, I-FLOWSUB, the VMI Shareholders nor the
INFUSYSTEM Shareholders shall take or permit to be taken any action which will
cause the Merger not to constitute a tax-free reorganization within the meaning
of Section 368(a) of the Code.

               6.11 Affiliates of VMI and INFUSYSTEM. Schedule 2.2 sets forth
the names of all persons or entities who or which may be deemed to be
"affiliates" of VMI for purposes of Rule 145 under the 1933 Act and Schedule 3.2
sets forth the names of all persons or entities who or which may be deemed to be
"affiliates" of INFUSYSTEM for purposes of Rule 145 under the 1933 Act
(collectively, the "RULE 145 AFFILIATES"). Each such Rule 145 Affiliate has
delivered to I-FLOW a written agreement (the "AFFILIATES AGREEMENT") in the form
attached hereto as Exhibit 6.11 that such Rule 145 Affiliate will not sell,
pledge, transfer or otherwise dispose of any shares of I-FLOW Common Stock
issued to such Rule 145 Affiliate pursuant to the Merger, except pursuant to an
effective registration statement or in compliance with Rule 145 or an exemption
from the registration requirements of the 1933 Act. I-FLOW agrees that, at all
times during which any Rule 145 Affiliate is subject to the resale restrictions
of Rule 144 and/or Rule 145, I-FLOW shall file all SEC Reports required to be
filed with the SEC under the 1933 Act and the 1934 Act including without
limitation in a manner that satisfies the requirements of Rule 144(c)(1).

               6.12 Restriction on Sale of I-FLOW Merger Shares. I-FLOW shall
use its commercially reasonable best efforts to cause the I-FLOW Merger Shares
to be registered under the 1933 Act within six (6) months of the Closing Date
and any additional shares of I-FLOW Common Stock issued pursuant to Section
1.6(a)(ii) to be registered under the 1933 Act within six (6) months of the date
of issuance. Subject to the provisions of this Section 6.12 and applicable laws,
each of the VMI Shareholders and the INFUSYSTEM Shareholders may sell up to
twenty-five percent (25%) of his pro rata share of (1) the I-FLOW Merger Shares

                                       47
<PAGE>   60

received in the Merger plus (2) any additional shares received pursuant to
Section 1.6(a)(ii) (collectively, "TOTAL SHARES") each six (6) months beginning
180 days following the Closing Date; provided, however, a VMI Shareholder or an
INFUSYSTEM Shareholder will be permitted to sell more than twenty-five (25%) of
his pro rata share of Total Shares, if (i) the aggregate number of Total Shares
being sold by all of the VMI Shareholders and the INFUSYSTEM Shareholders
collectively for that six (6) month period does not exceed twenty-five percent
(25%) of Total Shares, and (ii) the Shareholder requesting to sell more than
twenty-five percent (25%) of his pro rata share of Total Shares files with
I-FLOW, prior to the sale, a certificate signed by each VMI Shareholder and
INFUSYSTEM Shareholder consenting to such Shareholder's proposed sale of
additional Total Shares and confirming that they will not, in the aggregate,
sell shares in amounts that would cause the twenty-five percent (25%) limitation
to be violated. Notwithstanding the foregoing, if any VMI Shareholder or
INFUSYSTEM Shareholder is selling any portion of his pro rata share of the
Escrowed Shares (as defined herein) in accordance with this Section 6.12 prior
to the release, subject to the terms of the Escrow Agreement and Article IX
hereof, of the Escrow Fund on the second anniversary of the Effective Time, such
Shareholder shall deposit into the Escrow Fund an amount in cash equal to the
product of the number of Escrowed Shares to be sold by such Shareholder in
accordance with this Section 6.12 times the Closing Value of such Escrowed
Shares. Subject to the restrictions on the sale of I-FLOW Merger Shares set
forth herein and under applicable laws, each VMI Shareholder and each INFUSYSTEM
Shareholder listed on Schedule 7.1(d) shall be permitted to replace any portion
of his pro rata share of the Escrowed Shares with an amount of cash equal to the
product of the number of Escrowed Shares to be so replaced times the Closing
Value at any time prior to release, subject to the terms of the Escrow Agreement
and Article IX hereof, of the Escrow Fund on the second anniversary of the
Effective Time. Notwithstanding anything herein to the contrary, none of the VMI
Shareholders or the INFUSYSTEM Shareholders are obligated to sell any of their
shares of I-FLOW Merger Shares at any time.

               6.13 Profitability of Surviving Corporation. I-FLOW acknowledges
that it has performed due diligence on the businesses and operations of VMI and
INFUSYSTEM and that neither VMI nor INFUSYSTEM are making any guaranty regarding
the future profitability of the Surviving Corporation; provided, however, such
due diligence performed by I-FLOW shall not affect or be deemed to modify any
representation or warranty made by VMI, INFUSYSTEM or their respective
Shareholders herein.

               6.14 Spinka Lawsuit. VMI, INFUSYSTEM, the VMI Shareholders and
the INFUSYSTEM Shareholders acknowledge and agree that neither I-FLOW nor
I-FLOWSUB shall have any liability in connection with the lawsuit Scott Spinka
v. Infusystems II, Inc., et al., filed September 11, 1997 in the United States
District Court for the Eastern District of Michigan or the refiling of such
lawsuit to another venue or forum (the "SPINKA LAWSUIT") and that the VMI
Shareholders shall jointly and severally indemnify I-FLOW and I-FLOWSUB for any
and all Damages (as defined herein) either of them shall incur or suffer which
arise, result from or relate to the Spinka Lawsuit or any action related to or
arising out of any of the allegations within the Spinka Lawsuit.

                       (iv) On the second anniversary of the Effective Time (the
"EXPIRATION DATE") and subject to the terms of the Escrow Agreement, all of the
remaining Escrowed Shares and cash amounts in the Escrow Fund shall be
transferred to the VMI Shareholders and the INFUSYSTEM Shareholders according to
their pro rata interest in such Escrowed Shares and cash amounts, except for
Escrowed Shares and cash amounts which may be necessary to satisfy Buyer's
Claims under this Section 9.1(b). Subject to this Section 9.1(b), I-FLOW shall
execute and deliver any instructions to the Escrow Agent required by the Escrow
Agent to effect such transfer. If, on the Expiration Date, there exists any
Buyer's Claim which was timely asserted by the Indemnified Party but which is
not then finally resolved and discharged, there shall remain in the Escrow Fund
cash amounts and/or an aggregate number of Escrowed Shares with an aggregate
fair market value (determined by the Closing Value) equal to the reasonable
estimate (determined in accordance with Section 9.2) of the amount of Damages
asserted to be caused by such Buyer's Claim. Upon the final resolution and
discharge of any such Buyer's Claim, I-FLOW shall execute and deliver any
instructions to the Escrow Agent required by the Escrow Agent to effect the
transfer of any shares of Escrowed Shares and cash amounts remaining in the
Escrow Fund to the VMI Shareholders and the INFUSYSTEM Shareholders according to
their pro rata interest therein.

               9.2 Notice of Claim. The Indemnified Party shall promptly notify
the Shareholder Representative in writing of any Buyer's Claim asserted against
or imposed upon or incurred by it that might give rise to any indemnity
obligation hereunder (a "NOTICE OF CLAIM"), specifying the basis and, if
possible, a reasonable estimate of the amount (as determined in good faith by
the Board of Directors of I-FLOW) of Damages sought by such Indemnified Party on
account thereof and in reasonable detail such information as the Indemnified
Party may have with respect to the matter that is the subject of the Notice of
Claim (including copies of any summons, complaint or other pleading that may
have been served on it and any written claim, demand, invoice, billing or other
document evidencing or asserting the same). The date of a Notice of Claim to the
Shareholder Representative shall mean (a) the date the Shareholder
Representative receives the registered or certified mail containing the Notice
of Claim, or (b) if the Notice of Claim is transmitted by courier, the date of
its delivery to the courier by the Indemnified Party or (c) if the Notice of
Claim is personally delivered, the date of such personal delivery, or (d) if the
Notice of Claim is delivered by facsimile transmission (with written or
facsimile confirmation of receipt), the date of such transmission. In the event
the Indemnified Party does not promptly notify the Shareholder Representative in
writing of any Buyer's Claim in accordance with this Section 9.2, the failure to
provide such prompt notification shall not relieve the VMI Shareholders or the
INFUSYSTEM Shareholders of any liability hereunder unless and then to the extent
such failure causes the Shareholder Representative to lose the right to assert a
reasonable defense to such Buyer's Claim.

               9.3 Defense and Settlement of Claims. The Shareholder
Representative shall have the right (without prejudice to the right of the
Indemnified Party to participate at its own expense through counsel of its own
choosing) to defend against any Buyer's Claim that is the subject of a Notice of
Claim and to pay the expenses thereof (including the expenses of counsel
reasonably acceptable to the Indemnified Party), and to control such defense if
he provides written notice of his intention to do so within fifteen (15)
business days of receipt of the Notice 


                                       60
<PAGE>   73

of Claim. The Indemnified Party shall cooperate fully in the defense of such
Buyer's Claim and shall make available to the Shareholder Representative or his
counsel all pertinent information under its control relating thereto. The
Indemnified Party shall have the right to elect to settle any such Buyer's
Claim; provided, however, there shall be no indemnification obligation with
respect to any monetary payment to any third party required by such settlement
unless the Shareholder Representative shall have consented in writing thereto,
which consent shall not be unreasonably withheld, delayed or conditioned.


                                    ARTICLE X

                          INDEMNIFICATION AND SURVIVAL

                        OF REPRESENTATIONS AND WARRANTIES

               10.1 Relationship to Escrow Fund. Indemnification for the
following shall be handled in accordance with this Article X: (i) all Seller's
Claims, (ii) all Buyer's Claims to the extent that the Escrow Fund is not
sufficient or has already been released from the Escrow and (iii) all Buyer's
Claims in connection with Seller's Obligations relating to Sections 2.19, 2.21,
2.29, 3.19, 3.21, 3.29, 6.14 or 6.16 hereof asserted after the second
anniversary of the Effective Time.

               10.2 Survival of Representations, Warranties, Covenants and
Agreements. The representations, warranties, covenants and agreements of VMI,
INFUSYSTEM, the VMI Shareholders, the INFUSYSTEM Shareholders, I-FLOW and
I-FLOWSUB contained herein or in any exhibit, schedule, document, certificate or
other instrument delivered by or on behalf of any party pursuant to this
Agreement shall survive for a period of two (2) years from the Closing Date,
except that Seller's Obligations relating to Sections 2.19, 2.21, 2.29, 3.19,
3.21, 3.29, 6.14 and 6.16 hereof shall survive for a period of three (3) years
from the Closing Date. Any investigations made by or on behalf of I-FLOW and
I-FLOWSUB or VMI and INFUSYSTEM prior to the Closing Date shall not affect
Buyer's Obligations or Seller's Obligations hereunder. Completion of the
transactions contemplated herein shall not be deemed or construed to be a waiver
of any right or remedy of I-FLOW and I-FLOWSUB or VMI, INFUSYSTEM, the VMI
Shareholders and the INFUSYSTEM Shareholders notwithstanding the existence of
any facts that I-FLOW and I-FLOWSUB or VMI INFUSYSTEM, the VMI Shareholders and
the INFUSYSTEM Shareholders knew or should have known at the time hereof or
thereof.

               10.3 Indemnification of I-FLOW and I-FLOWSUB. Notwithstanding any
resolution, consent or separate covenant of VMI, INFUSYSTEM, the VMI
Shareholders or the INFUSYSTEM Shareholders to the contrary, each of the VMI
Shareholders and each of the INFUSYSTEM Shareholders set forth on Schedule
7.1(d) shall severally indemnify, defend and hold harmless the Indemnified
Parties against and in respect of any and all Buyer's Claims; provided, however,
each of the VMI Shareholders and each of the INFUSYSTEM Shareholders set forth
on Schedule 7.1(d) shall jointly and severally indemnify, defend and 


                                       61
<PAGE>   74

hold harmless the Indemnified Parties against and in respect of any and all
Buyer's Claims in connection with the Spinka Lawsuit. For the purposes of
defining the several liability of each of the VMI Shareholders and each of the
INFUSYSTEM Shareholders under this Section 10.3, the obligations of each VMI
Shareholder and each INFUSYSTEM Shareholder shall be limited to the percentages
set forth on Schedule 10.3. Notwithstanding the foregoing, (i) the Indemnified
Parties shall not be entitled to indemnification by the VMI Shareholders or the
INFUSYSTEM Shareholders under this Agreement for the first Ten Thousand Dollars
($10,000) in the aggregate of Buyer's Claims (unrelated to Individualized
Billing Adjustments), but after such first Ten Thousand Dollars ($10,000) shall
be entitled to full indemnification for any Buyer's Claims, (ii) during the
period beginning at the Effective Time and ending on the first anniversary of
the Effective Time (the "FIRST YEAR PERIOD"), the Indemnified Parties shall not
be entitled to indemnification by the VMI Shareholders or the INFUSYSTEM
Shareholders under this Agreement for the first Thirty Thousand Dollars
($30,000) in the aggregate of Buyer's Claims relating to Individualized Billing
Adjustments, but after such first Thirty Thousand Dollars ($30,000) shall be
entitled to full indemnification for any Buyer's Claims relating to
Individualized Billing Adjustments during the First Year Period, and (iii)
during the period beginning on the first anniversary of the Effective Time and
ending on the second anniversary of the Effective Time (the "SECOND YEAR
PERIOD"), the Indemnified Parties shall not be entitled to indemnification by
the VMI Shareholders or the INFUSYSTEM Shareholders under this Agreement for the
first Thirty Thousand Dollars ($30,000) in the aggregate of Buyer's Claims
relating to Individualized Billing Adjustments, but after such first Thirty
Thousand Dollars ($30,000) shall be entitled to full indemnification for any
Buyer's Claims relating to Individualized Billing Adjustments during the Second
Year Period. The maximum indemnification obligation of the VMI Shareholders and
the INFUSYSTEM Shareholders under this Agreement shall be limited to Two Million
Eight Hundred Ninety-Seven Thousand Six Hundred Sixty-Eight Dollars
($2,897,668).

               10.4 Claims for Indemnification. Whenever any Buyer's Claim shall
arise for indemnification under this Article X, I-FLOW shall notify the VMI
Shareholders and the INFUSYSTEM Shareholders of the Buyer's Claim and, when
known, the facts constituting the basis for such Claim. In the event of any
Claim for indemnification hereunder resulting from or in connection with any
legal proceedings by a third party, such notice shall also specify, if known,
the amount or an estimate of the amount of the liability arising therefrom.
I-FLOW and I-FLOWSUB shall give the VMI Shareholders and the INFUSYSTEM
Shareholders a reasonable opportunity to defend any such Buyer's Claim at their
own expense and with counsel of their own selection and reasonably acceptable to
I-FLOW, provided that I-FLOW and I-FLOWSUB shall at all times also have the
right to fully participate in the defense at their own expense. If the VMI
Shareholders and the INFUSYSTEM Shareholders shall, within a reasonable time
after notice, fail to defend, I-FLOW and I-FLOWSUB shall have the right to
undertake the defense of, and to compromise or settle (exercising reasonable
business judgment) the Buyer's Claim on behalf, for the account, and at the risk
of, the VMI Shareholders and the INFUSYSTEM Shareholders. I-FLOW shall notify
the VMI Shareholders and the INFUSYSTEM Shareholders in writing of the existence
of any Buyer's Claim to which the VMI Shareholders and the INFUSYSTEM
Shareholders' indemnification would apply, but failure to so notify the VMI
Shareholders and the INFUSYSTEM 


                                       62
<PAGE>   75

Shareholders shall not relieve the VMI Shareholders and the INFUSYSTEM
Shareholders of any liability hereunder unless and then to the extent such
failure causes the VMI Shareholders and the INFUSYSTEM Shareholders to lose the
right to assert a reasonable defense to such Buyer's Claim.

               10.5 Manner of Indemnification of I-FLOW and I-FLOWSUB.
Indemnification by the VMI Shareholders and the INFUSYSTEM Shareholders under
this Article X shall be effected by the delivery of a cashier's or certified
check by the VMI Shareholders and INFUSYSTEM Shareholders not later than ten
(10) business days from the date notice of such Buyer's Claim was given to the
VMI Shareholders and the INFUSYSTEM Shareholders.

               10.6 Indemnification of VMI and INFUSYSTEM. I-FLOW and I-FLOWSUB
jointly and severally shall indemnify, defend and hold harmless the VMI
Shareholders and the INFUSYSTEM Shareholders against and in respect of any and
all Seller's Claims.

               10.7 Claims for Indemnification. Whenever any Seller's Claim
shall arise for indemnification of under this Article X, the VMI Shareholders
and the INFUSYSTEM Shareholders shall notify I-FLOW and I-FLOWSUB of the
Seller's Claim and, when known, the facts constituting the basis for such
Seller's Claim. In the event of any Seller's Claim for indemnification hereunder
resulting from or in connection with any Seller's Claim or legal proceedings by
a third party, such notice shall also specify, if known, the amount or an
estimate of the amount of the liability arising therefrom. The VMI Shareholders
and the INFUSYSTEM Shareholders shall give I-FLOW and I-FLOWSUB a reasonable
opportunity to defend any such Seller's Claim at its own expense and with
counsel of their own selection and reasonably acceptable to the VMI Shareholders
and the INFUSYSTEM Shareholders, provided that the VMI Shareholders and the
INFUSYSTEM Shareholders shall at all times also have the right to fully
participate in the defense at their own expense. If I-FLOW and I-FLOWSUB shall,
within a reasonable time after notice, fail to defend, the VMI Shareholders and
the INFUSYSTEM Shareholders shall have the right to undertake the defense of,
and to compromise or settle (exercising reasonable business judgment) the
Seller's Claim on behalf, for the account, and at the risk of, I-FLOW and
I-FLOWSUB. The VMI Shareholders and the INFUSYSTEM Shareholders shall notify
I-FLOW and I-FLOWSUB in writing of the existence of any Seller's Claim to which
I-FLOW and I-FLOWSUB's indemnification would apply, but failure to so notify
I-FLOW and I-FLOWSUB shall not relieve I-FLOW and I-FLOWSUB of any liability
hereunder unless and to the extent such failure causes I-FLOW and I-FLOWSUB to
lose the right to assert a reasonable defense to such Seller's Claim.

               10.8 Manner of Indemnification of the VMI Shareholders and the
INFUSYSTEM Shareholders. Indemnification by I-FLOW and I-FLOWSUB under this
Article X shall be effected by the delivery of a cashier's or certified check
not later than ten (10) business days from the date the notice of such Claim was
given to I-FLOW and I-FLOWSUB.

               10.9 Equitable Contribution. Nothing herein shall diminish any
party's right to seek equitable contribution from another party.
