          Item 2. Acquisition or Disposition of Assets

          On February 15, 1999, Irwin Naturals/4Health, Inc., a Utah
corporation, ("IN"), Health & Vitamin Express, Inc., a California corporation
("HVE"), and Messrs.  David Mandel, Jeffrey Segal and Gordon Barker, the
shareholders of HVE (the "Selling Shareholders"), entered into an Agreement and
Plan of Merger (the "Merger Agreement"), providing for the merger (the "Merger")
of HVE with and into HealthZone.com, a California corporation and newly formed
wholly-owned subsidiary of IN ("HZ"). On February 17, 1999, pursuant to the
terms of the Merger Agreement, HVE was merged with and into HZ, and, in
connection therewith, the shares of common stock, no par value, of HVE (the "HVE
Common Stock"), issued and outstanding immediately prior to the Merger were
converted into (i) the immediate right to receive an initial tranche of 363,636
shares (the "Initial Shares") of the common stock, par value $0.01 per share, of
IN ("IN Common Stock"), and (ii) contingent rights to receive up to an
additional 363,636 shares of IN Common Stock (the "Earn-Out Shares" and together
with the Initial Shares, the "Shares"), issuable if HZ achieves certain net
revenues and pre-tax profits targets.

          Under the terms of the Merger Agreement, IN has the right to
repurchase up to 65% of the Shares at a price, depending on the circumstances,
of either $9.63 per Share or $13.75 per Share.  This repurchase right terminates
as early as February 13, 2000 with respect to certain Shares and may extend as
late as February 13, 2007 with respect to other Shares.

          The Selling Shareholders will receive the Earn-Out Shares
automatically, whether or not the HZ net revenues or pre-tax profits targets are
reached, (i) if IN does not invest at least $4 million in HZ by August 13, 2000
and a further $6 million in HZ by February 13, 2002 or (ii) upon a change in
control of IN.

          A complete description of all of the terms and conditions of the
Merger, including the Share issuances and the related repurchase rights is set
forth in the Merger Agreement attached as Exhibit 10.1 hereto.

          HVE was organized in September 1992.  Since its formation, HVE has
been engaged in the online sale of vitamins and other health-related products.
IN expects that the principal employees of HVE will continue as employees of HZ.

          HZ was organized in February 1999 for the purpose of acquiring the
business of HVE. HZ has no material assets or operations other than the business
of HVE.

                          AGREEMENT AND PLAN OF MERGER

     THIS AGREEMENT AND PLAN OF MERGER, effective as of February 15, 1999 (this
"Agreement"), by and among Irwin Naturals/4Health, Inc., a Utah corporation
(together with HZ (as defined below), "IN"), Health & Vitamin Express, Inc., a
California corporation ("HVE") and Mr. David Mandel ("Mandel"), Mr. Jeffrey D.
Segal ("Segal") and Mr. Gordon D. Barker ("Barker", and together with Mandel and
Segal, the "Selling Shareholders"; the Selling Shareholders and HVE are
hereinafter collectively referred to as the "Sellers").

                                    RECITALS

(c)     HVE, upon the terms and subject to the conditions of this Agreement and
     in accordance with the General Corporation Law of the State of California
     ("California Law"), will merge (the "Merger"), with and into
     HealthZone.com, a California corporation and wholly-owned subsidiary of IN
     ("HZ") and pursuant thereto, the shares (the "HVE Shares") of common stock,
     no par value per share of HVE ("HVE Common Stock"), issued and outstanding
     immediately prior to the Effective Time (as defined herein) of the Merger,
     not owned directly or indirectly by IN or HVE, will be converted at the
     Effective Time into the right to receive the Merger Consideration (as
     defined below).
 
(c)  For federal income tax purposes, it is intended that the Merger qualify as
     a tax-free reorganization under the provisions of Section 368(a) of the
     United States Internal Revenue Code of 1986 as amended (the "Code").
 
     NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged and confirmed, the parties hereto
agree as follows:

                                   THE MERGER

     SECTION 1.1.   The Merger.  Upon the terms and subject to the conditions
                    ----------                                               
set forth in this Agreement, and in accordance with California Law, at the
Effective Time, HVE shall be merged with and into HZ(each a "Constituent

place at the offices of IN at 10549 West Jefferson Boulevard, Culver City, CA
90232 as soon as practicable (but in any event within five business days) after
the satisfaction or, if permissible, waiver of the conditions set forth in
Article VII, or at such other date, time and place as HVE and IN may agree. The
date on which the Closing takes place is referred to herein as the "Closing
Date". As promptly as practicable on the Closing Date, the parties hereto shall
cause the Merger to be consummated by executing and filing Agreement of Merger,
in substantially the form of Exhibit A attached hereto, with the Secretary of
State of the State of California (the date and time of such filing, or such
later date or time agreed upon by HVE and IN and set forth therein, being the
"Effective Time"). For all tax purposes, the Closing shall be effective at the
end of the day on the Closing Date.

     SECTION 1.3.   Effect of the Merger.  At the Effective Time, to the full
                    --------------------                                     
extent provided under California Law, the Surviving Corporation shall possess
all the rights, privileges, powers and franchises of a public as well as of a
private nature, and be subject to all the restrictions, disabilities and duties
of each of the Constituent Corporations; and any and all rights, privileges,
powers and franchises of each of the Constituent Corporations, and all property,
real, personal and mixed, and all debts due to either of the Constituent
Corporations on whatever account, as well as stock subscriptions and all other
things in action belonging to each of the Constituent Corporations, shall be
vested in the Surviving Corporation; and all property, rights, privileges,
powers and franchises, and all and every other interest shall be thereafter as
effectually the property of the Surviving Corporation as they were of the
Constituent Corporations, and the title to any real estate vested by deed or
otherwise, in either of the Constituent Corporations, shall not revert or be in
any way impaired; but all rights of creditors and all liens upon any property of
either of the Constituent Corporations shall be preserved unimpaired, and all
debts, liabilities and duties of the Constituent Corporations shall thenceforth
attach to the Surviving Corporation and may be enforced against it to the same
extent as if said debts, liabilities and duties had been incurred or contracted
by it.

     SECTION 1.4.   Articles of Incorporation; Bylaws.  At the Effective Time,
                    ---------------------------------                         
the articles of incorporation of HZ shall be the articles of incorporation of
the Surviving Corporation and thereafter shall continue to be its articles of
incorporation until amended as provided therein and pursuant to California Law.
The bylaws of HZ shall be the bylaws of the Surviving Corporation and thereafter
shall continue to be its bylaws until amended as provided therein and in the
articles of incorporation and pursuant to California Law.

     SECTION 1.5.   Directors and Officers.  Immediately after the Effective
                    ----------------------                                  
Time, the officers and directors of the Surviving Corporation shall be the
individuals identified as such in Schedule 1.05, each of such directors and
officers to hold office in accordance with the articles of incorporation and
bylaws of the Surviving Corporation, in each case until his successor is duly
elected or appointed and qualified.

     SECTION 1.6.   Merger Consideration; Conversion and Cancellation of
                    ----------------------------------------------------
Securities.  At the Effective Time, by virtue of the Merger and without any
- ----------                                                                 
action on the part of HVE, HZ or their respective stockholders:

          (1) Subject to the other provisions of this Article II, each share of
HVE Common Stock issued and outstanding immediately prior to the Effective Time
(excluding any HVE Common Stock described in Section 2.01(c) of this Agreement)
shall be converted into the right to receive the Merger Consideration

          (2) Notwithstanding any provision of this Agreement to the contrary,
each share of HVE Common Stock held in the treasury of HVE, and each share of
HVE Common Stock owned by IN or any direct or indirect wholly owned subsidiary
of IN immediately prior to the Effective Time shall be canceled and extinguished
without any conversion thereof and no payment shall be made with respect
thereto.

          (3) All shares of HVE Common Stock shall cease to be outstanding and
shall automatically be canceled and retired, and each certificate previously
evidencing HVE Common Stock, immediately prior to the Effective Time (other than
HVE Common Stock described in Section 2.01(b) of this Agreement) (the "Converted
Shares" or "Converted Share Certificates," as the case may be) shall thereafter
represent the right to receive, subject to Section 2.02(d) of this Agreement,
(the Merger Consideration).  The holders of Converted Share Certificates shall
cease to have any rights with respect to such Converted Shares except as
otherwise provided herein or by law.

          (4) All shares of IN Common Stock issued to holders of HVE Common
Stock in the Merger shall be issued in a transaction intended to qualify for the
exemption from registration provided by Section 4(2) of the Securities Act of
1933, as amended (the "Securities Act") and Regulation D promulgated thereunder
("Regulation D") and shall be deemed "restricted securities" as defined in Rule
144 promulgated under the Securities Act.

     SECTION 1.7.   Merger Consideration.
                    -------------------- 

          (1) In consideration for the HVE Shares:

          (1) at the Closing, IN shall issue to the Selling Shareholders an
aggregate of 363,636 shares (the "Initial HVE Shares") of IN Common Stock, to be
allocated among the Selling Shareholders as set forth in Schedule 2.02 (a)
hereto;

          (2) for each $1,000,000.00 of Net Revenues (as defined below) from

                                      -3-
<PAGE>
 
Internet sales received by the Internet Division (as defined below) during any
period of twelve consecutive  months during the first forty-two consecutive
months after the Closing Date, IN shall issue to the Selling Shareholders 90,909
shares (the "Revenues Earn-Out Shares"), of IN Common Stock up to a maximum
aggregate amount of 272,727 shares of IN Common Stock, such shares to be
allocated among the Selling Shareholders as set forth on Schedule 2.02(a)
hereto; as used herein, the "Internet Division" shall mean the division of IN
making sales of products out of IN or Internet Division inventory on-line or in
e-commerce,  and "Net Revenues" shall mean the gross revenues (including,
without limitation, advertising revenues) of the Internet Division less returns;
and

          (3) if the Division Pre-Tax Profits (as defined below) for any
calendar year after the Closing Date during the first seven (7) years after the
Closing Date shall equal or exceed $2,000,000.00, IN shall, once and only once,
issue to the Selling Shareholders an aggregate of 90,909 shares (the "Profits
Earn-Out Shares") of IN Common Stock, to be allocated among the Selling
Shareholders as set forth on Schedule 2.02(a) hereto; as used herein, "Division
Pre-Tax Profits" shall mean the net income of the Internet Division, including
only those expenses properly attributable to the activities of the Internet
Division, as computed without deduction for any federal, state or other income
taxes, as determined by IN's accountants in accordance with GAAP (as defined
below).

     The Initial HVE Shares, the Revenues Earn-Out Shares and the Profits Earn-
Out Shares are collectively referred to herein as the "Merger Consideration".

          (2) Notwithstanding the provisions of subsection (a) of Section 2.02,
if IN does not invest or contribute to the Internet Division at least (A)
$4,000,000.00 during the eighteen month period following the Closing Date and
(B) $10,000,000.00 (inclusive of the $4,000,000.00 provided in clause (A) above)
during the thirty six month period following the Closing Date (each, a "Funding
Failure"), then the Selling Shareholders shall automatically be entitled to
receive at the time of such Funding Failure the maximum allowable number of
Revenues Earn-Out Shares and the Profits Earn-Out Shares without regard to the
revenue or profits of the Internet Division.

          (3) Any revenue and income of IN attributable to on-line or e-commerce
sales generated as a result of the purchase by IN of any mail direct to consumer
catalog order wholesale vitamin or health related companies after the Closing
and the conversion of telephone orders from such companies to  on-line or e-
commerce orders, shall be included in the calculation of Net Revenues and
Division Pre-Tax Profits, respectively.

          (4) In the event that IN acquires any company with on-line and e-
commerce sales, IN shall provide the Internet Division with access to the
customer database of such company.

          (5) In the event that a third-party (i) acquires all or substantially
all of the assets of IN or (ii) acquires more than 50% of the issued and
outstanding capital stock of IN, or that IN 

                                      -4-
<PAGE>
 
is merged or consolidated with a third-party and the holders of IN Common Stock
immediately prior to such merger or consolidation do not own more than 50% of
the capital stock of the surviving corporation of such merger or consolidation,
then the Selling Shareholders shall automatically be entitled to receive the
maximum allowable number of Revenues Earn-Out Shares and Profits Earn-Out Shares
without regard to the revenues or profits of the Internet Division.


     SECTION 1.8.   Right of Repurchase.
                    ------------------- 
 
          (1) Subject to subsections (b), (c), (d), (e) and (f) of this Section
2.03, IN shall have the right (the "Repurchase Option"), in its sole discretion,
to repurchase from the Selling Shareholders pro-rata all or any portion, up to
65%, of the Merger Consideration that has been issued to the Selling
Shareholders, for a period of one (1) year following the date of issuance (the
"Repurchase Period"), at a purchase price of $13.75 per share (the "Repurchase
Price"); provided, however, that for the purpose of determining the termination
         --------  -------                                                     
of the Repurchase Period with respect to the Initial HVE Shares, the Initial HVE
Shares shall be deemed to have been issued contemporaneously with the issuance
of an equivalent number of Revenues Earn-Out Shares and the Profits Earn-Out
Shares.   For example, if the first 90,909 Revenues Earn-Out Shares are issued
to the Selling Shareholders on August 1, 2000 and the second 90,909 Revenues
Earn-Out Shares are issued to the Selling Shareholders on November 15, 2001 and
no Profits Earn-Out Shares have been issued prior to November 15, 2001, then the
Repurchase Period for the first 90,909 Initial HVE Shares will terminate on July
31, 2001 and the Repurchase Period for the second 90,909 Initial HVE Shares will
terminate on November 14, 2002.  In all cases, the Repurchase Period with
respect to the Initial HVE Shares shall begin on the Closing Date.  As used in
this Agreement, pro-rata with respect to the Selling Shareholders shall mean in
proportion to their respective percentage allocations of the Merger
Consideration as set forth in Schedule 2.02(a).  In the event that no Profits
Earn-Out Shares and/or no Revenues Earn-Out Shares are issued pursuant to this
Agreement, the Repurchase Period with respect to Mandel's portion of the Initial
HVE  Shares shall expire thirty-six months following the Closing Date.

          (2) Notwithstanding the provisions of subsection (a) of this Section
2.03 and subject to the provisions of subsection (c) of this Section 2.03, (i)
if IN exercisers the Repurchase Option during the first twelve months following
the Closing Date, the Repurchase Option shall be applied pro-rata among the
Selling Shareholders and (ii) at any time that IN shall exercise the Repurchase
Option after twelve months from the Closing Date, the Repurchase Option shall be
exercisable as to Mandel only with respect up to a maximum of 73% of his Merger
Consideration.

          (3) Notwithstanding the provisions of subsection (a) of this Section
2.03, the maximum number of Initial HVE Shares subject to the Repurchase Option
shall be 213,636 shares and the other 150,000 Initial HVE Shares shall not be
subject to the Repurchase Option and such 150,000 Initial HVE Shares which are
not subject to the Repurchase Option shall be allocated among the Selling
Shareholders in the same proportions as are set forth in Schedule 2.02(a).

                                      -5-
<PAGE>
 
          (4) Notwithstanding the provisions of subsection (a) of this Section
2.03, the Repurchase Period with respect to the Initial HVE Shares, the Revenues
Earn-Out Shares and the Profits Earn-Out-Shares allocated to Segal or Barker
shall, in all cases, expire one year from the Closing Date notwithstanding the
fact that some or all of the Revenues Earn-Out Shares or the Profits Earn-Out
Shares may not have been issued by such date.

          (5) If on date that IN shall exercise the Repurchase Option, the
closing bid price of IN Common Stock on a national securities exchange or the
NASDAQ National Market System (the "Market Price") shall be greater than $20.00
per share, then IN shall pay to the Selling Shareholders pro-rata an amount (the
"Market Profit") equal to fifty percent (50%) of the product of (x) the
difference of the Market Price less $20.00 multiplied by (y) the number of
shares repurchased by IN pursuant to the Repurchase Option.

          (6) Notwithstanding the provisions of subsection (a) of this Section
2.03, in the event that the Selling Shareholders receive their Revenues Earn-Out
Shares and Profits Earn-Out Shares because of a Funding Failure and the Net
Revenues and Division Pre-Tax Profits thresholds set forth in clauses (ii) and
(iii) of Section 2.02 have not been met, then the Repurchase Price with respect
to such shares and the equivalent amount of Initial HVE Shares shall be reduced
from $13.75 per share to $9.63 per share.

          (7) At any time that IN shall be entitled to exercise the Repurchase
Option, it may do so by sending a written notice (the "Repurchase Notice") to
each Selling Shareholder setting forth (i) the number of shares with respect to
which IN is exercising the Repurchase Option, (ii) the purchase price therefor,
(iii) the closing date on which the Selling Shareholders shall deliver share
certificates evidencing the indicated number of shares together with stock
powers duly executed in blank and IN shall deliver the purchase price and (iv)
if applicable, the amount of Market Profit payable by IN to such Selling
Shareholder at the closing of the repurchase.  The closing date for any exercise
of the Repurchase Option shall be no more than five business days and no less
than three business days after IN shall have sent the Repurchase Notice to the
Selling Shareholders; provided that notwithstanding anything to the contrary
                      --------                                              
contained herein, in no event shall IN be entitled to designate a closing date
for the exercise of the Repurchase Option with respect to any Merger
Consideration that is after the expiration of the related Repurchase Period.


     SECTION 1.9.   Exchange and Surrender of Certificates.
                    ---------------------------------------

          (1) At the Closing, IN shall deliver to each registered holder of a
Converted Share Certificate against delivery by such holder of all of his
Converted Share Certificates representing issued and outstanding shares of HVE
Common Stock a certificate representing that number of whole shares of IN Common
Stock which such holder has the right to receive in exchange for the Converted
Share Certificates surrendered pursuant to the provisions of this Article II
(after taking into account all Converted Shares then held by such holder), and
the 

                                      -6-
<PAGE>
 
Converted Share Certificates so surrendered shall forthwith be canceled.
The certificate representing the IN Common Stock shall bear a restrictive legend
in the form set forth in Exhibit B.  Until surrendered as contemplated by this
Section 2.04, each Converted Share Certificate shall be deemed at any time after
the Effective Time to represent only the IN Common Stock into which the
Converted Shares represented by such Converted Share Certificate have been
converted as provided in this Article II.

          (2) After the Effective Time, there shall be no further registration
of transfers of HVE Common Stock.  If, after the Effective Time, certificates
representing shares of HVE Common Stock are presented to the Surviving
Corporation, they shall be canceled and exchanged for the Merger Consideration
provided for in this Agreement in accordance with the procedures set forth
herein.

          (3) Any portion of the Merger Consideration that remains unclaimed by
the holders of shares of HVE Common Stock, one year after the Effective Time
shall be returned to the Surviving Corporation, upon demand, and any such holder
who has not exchanged his  shares of HVE Common Stock in accordance with this
Section 2.04 prior to that time shall thereafter look only to the Surviving
Corporation for payment of the Merger Consideration in respect of his shares of
HVE Common Stock.  Notwithstanding the foregoing, the Surviving Corporation
shall not be liable to any holder of Converted Shares for any amount paid to a
public official pursuant to applicable abandoned property, escheat or similar
laws.

          (4) No dividends, interest or other distributions with respect to
shares of IN Common Stock shall be paid to the holder of any unsurrendered
Converted Share Certificates unless and until such Converted Share Certificates
are surrendered as provided in this Section 2.04.  Upon such surrender, IN shall
pay, without interest, all dividends and other distributions payable in respect
of such shares of IN Common Stock on a date subsequent to, and in respect of a
record date after, the Effective Time.


                                  ARTICLE III

                   REPRESENTATIONS AND WARRANTIES OF SELLERS

     Each of the Sellers (other than Barker, whose representations hereunder are
limited to the last sentence of Section 3.03(a)), individually with respect to
the representations with respect to the Selling Shareholders set forth in
Sections 3.03(c), 3.04, 3.05 and 3.22, and jointly and severally with respect to

business conducted by it or the ownership or leasing of its properties makes
such qualification necessary, other than where the failure to be so duly
qualified and in good standing would not have an HVE Material Adverse Effect.
The term "HVE Material Adverse Effect" as used in this Agreement shall mean any
change or effect that, individually or when taken together with all other such
changes or effects, would be reasonably likely to be materially adverse to the
assets, liabilities, financial condition, results of operations or current or

party or bound, and such outstanding shares or other equity interests owned by
HVE or any Selling Shareholder are owned free and clear of all security
interests, liens, claims, pledges, agreements, limitations on HVE's or any
Selling Shareholder's voting rights, charges or other encumbrances of any nature
whatsoever.

          (2) Except as disclosed in Schedule 3.03(b), there are no options,

Selling Shareholder is a party or by which HVE or any Selling Shareholder is or

          (3) Each Selling Shareholder is the record and beneficial owner of the
number of shares of HVE Common Stock set forth opposite such Selling
Shareholder's name below, and each Selling Shareholder has full power and legal

or order of, or to make any filing with or notification to, any governmental or
regulatory authority, domestic or foreign (collectively, "Governmental
Entities"), except  for filing appropriate merger documents as required by
California Law; and  where the failure to obtain such consents, licenses,
permits, approvals, waivers, authorizations or orders, or to make such filings
or notifications, would not, either individually or in the aggregate, materially
interfere with HVE's performance of its obligations under this Agreement and
would not have an HVE Material Adverse Effect.

is aware of the risks attendant to an investment in the IN Common Stock.  He has
relied solely upon the independent investigations made by him and his
representatives and IN's representations and warranties set forth herein in
making a decision to approve the Merger and to acquire the IN Common Stock and
has a full understanding and appreciation of the risks inherent in such a
speculative investment.  In connection with such investigation, he and his

or for offer or resale in connection with, a distribution thereof in violation
of any Securities Laws. He understands that the effect of such representations
and warranties is that such Stock must be held indefinitely unless the sale or
transfer thereof is subsequently registered under applicable Securities Laws or
an exemption from such registration is available at the time of the proposed
sale or transfer thereof. Except as provided in Section 6.02 hereof, IN is under
no obligation to file a registration statement under the Securities Act covering
the sale or transfer of the IN Common Stock or otherwise to register such Stock

defined in Rule 501 of Regulation D, in the case of Mandel, based on among other
things his ownership of HVE Common Stock; and that the statements contained in

rules and regulations promulgated thereunder, or (b) such Stock is included in a
currently effective registration statement under the Securities Act. No Selling
Shareholder has been convicted of any felony or misdemeanor in connection with
the purchase and sale of any security or involving the making of any false
filing with the Securities and Exchange Commission ("Commission"). No Selling
Shareholder nor HVE, nor any officer, director and/or shareholder of HVE, is

judgment or decree of any court of competent jurisdiction, permanently
restraining or enjoining, such person from engaging in or continuing any conduct
or practice in connection with the purchase and sale of any security or
involving the making of any false filing with the Commission. Each Selling
Shareholder agrees to secure and furnish to IN prior to the Effective Time

any, addressed to IN containing the same representations and warranties made by
each Selling Shareholder in this Section 3.22.

     SECTION 1.32.  Intellectual Property.  Schedule 3.23 lists all the
                    ---------------------

conditions as in effect prior to the Effective Time. Except as set forth in
Schedule 3.23, there are no claims or proceedings pending or, to any Seller's
knowledge, threatened, against HVE asserting that HVE is infringing or engaging
in the unauthorized use of any Intellectual Property of any other person or
entity. Schedule 3.23 sets forth all agreements and arrangements (i) pursuant to
which HVE has licensed Intellectual Property to, or the use of Intellectual
Property in other areas permitted (through non-assertion, settlement or similar
agreements or otherwise) by, any other person and (ii) pursuant to which HVE has
had Intellectual Property licensed to it, or has otherwise been permitted to use
Intellectual Property (through non-assertion, settlement or similar agreements
or otherwise). All of the agreements or arrangements to the extent set forth on

and no Seller is aware that any default exists thereunder by HVE or by any other
party thereto; (x) are free and clear of liens; and (y) do not contain any

have, individually or in the aggregate, a IN Material Adverse Effect; (ii) any
declaration, setting aside or payment of any dividend or other distribution

proceeding, arbitration or, to the knowledge of IN, investigation of any kind,
at law or in equity (including actions or proceedings seeking injunctive relief)
pending or, to the knowledge of IN, threatened, against IN or any of its
properties or rights (except for claims, actions, suits, litigation,
proceedings, arbitrations or investigations which would not have a IN Material
Adverse Effect), and IN is not subject to any continuing order of, consent
decree, settlement agreement or other similar written agreement with, or, to the
knowledge of IN, continuing investigation by, any

warranty made in this Section 4.11 to be true and correct which would not have a
IN Material Adverse Effect:

          (1) Except to the extent that the applicable statute of limitations
has expired, all Returns required to be filed by or on behalf of IN have been
duly filed on a timely basis with the appropriate Governmental Entities and such
Returns are true, correct and complete.  Except to the extent that the
applicable statute of limitations with respect thereto has expired, all Taxes
have been duly paid in full or a provision has been made in accordance with
generally accepted accounting principles for the payment of all Taxes for all
periods covered by such Returns or with respect to any period prior to the
Effective Time.  IN has disclosed on its income tax returns all positions taken
therein which could give rise to a substantial understatement penalty within the
meaning of Code Section 6662.  No waiver or extension of any statute of
limitations is in effect with respect to Taxes or Returns of IN.

          (2) IN has complied in all respects with all applicable laws, rules
and regulations relating to the payment and withholding of Taxes (including any
estimated Taxes and the withholding of Taxes pursuant to Sections 1441 and 1442
of the Code or similar provisions under any foreign laws) and have, within the
time and the manner prescribed by law, withheld from employee wages and paid
over all amounts withheld under applicable laws.

          (3) There is no audit of any of the Returns of IN by a Governmental
Entity in process or threatened and there is no material dispute or claim
concerning any liabilities for Taxes of IN either raised or reasonably expected
to be raised by any taxing authority.  There are no liens on any assets of IN
with respect to Taxes, other than liens set forth in Schedule 4.11 of the IN
Disclosure Schedule for Taxes that are being contested in good faith through
appropriate proceedings and for which appropriate reserves have been
established.

          (4) IN has made available to HVE complete copies of (i) all federal
income tax returns of IN for all periods open under the statute of limitations
for assessments and (ii) examination reports, and statements of deficiencies
assessed against IN.

          (5) No consent under Section 341(f) of the Code has been filed with
respect to IN.

          (6) IN has not entered into any compensatory agreements with respect
to the performance of services under which payment would result in a
nondeductible expense pursuant to Section 280G of the Code.

          (7) IN has not agreed, nor is it required to make, prior to the
Effective Time, 

                                      -27-

any adjustment under Code Section 481(a) by reason of a change in accounting
method or otherwise.

          (8) IN has not issued or assumed any corporate acquisition
indebtedness that is subject to Sections 279(a) and (b) of the Code.

          (9) The amount of liability for unpaid Taxes of IN for all periods
ending on or before the Effective Time will not, in the aggregate, materially
exceed the amount of the liability accruals for Taxes reflected on the balance
sheet of IN filed in it Quarterly Report on Form 10-Q for the fiscal quarter
ended September 30, 1998 (the "IN Balance Sheet").

          (10) The tax returns provided by IN to HVE contain accurate and
complete information with respect to the net operating losses, net operating
loss carry forwards and other tax attributes of IN, and the extent to which they
are subject to any limitation under Code Sections 381, 382, 383 or 384, or any
other provision of the Code or the federal consolidated return regulations (or
any predecessor provision of any Code section or the regulations) and, apart
from any such limitations and apart from any limitation that would be imposed as
a result of the Merger, there is nothing that would prevent IN from utilizing
these net operating losses, net operating loss carry forwards or other tax
attributes as so limited if sufficient income were realized.

          (11) IN is not required to treat any of its assets as owned by another
person for federal income tax purposes or as tax-exempt bond property or as tax-
exempt use property within the meaning of Section 168 of the Code.

     SECTION 1.59.  Covenants and Consent of the Selling Shareholders.  In lieu
                    -------------------------------------------------          
of a meeting of stockholders, the Merger, this Agreement and the transactions
contemplated hereby shall be approved upon written consent, without a meeting,
in accordance with the provisions of California Law, and the execution and
delivery of this Agreement by the Selling Shareholders shall constitute their
written consent to the Merger, this Agreement and the consummation of the
transactions contemplated hereby for all purposes required by the applicable
provisions of California Law in order to approve and effectuate the Merger.
Each Selling Shareholder hereby irrevocably waives any and all rights to assert
any dissenters' rights and appraisal rights granted under the provisions of any
Law with respect to the Merger, this Agreement or the transactions contemplated
hereby.  HVE hereby agrees to secure similar proxies and written consents from
all other HVE stockholders, if any, and deliver them to IN prior to the
Effective Time in sufficient time to meet all applicable procedural requirements
of California Law regarding stockholder approval of mergers or other business
combinations.  Prior to the Closing Date, the Selling Shareholders shall not,
directly or indirectly, sell, transfer, convey, encumber, pledge, assign,
hypothecate, or otherwise dispose of or lose possession of any of their shares
of HVE Common Stock.

     SECTION 1.60.  Affirmative Covenants of IN.
                    --------------------------- 

          (1) IN hereby covenants and agrees that, at or prior to the Effective
Time, unless otherwise expressly contemplated by this Agreement or consented to
in writing by HVE, IN will:

          (1) continue to operate its business in all material respects in the
usual and ordinary course, consistent with past practice;

          (2) use all reasonable efforts to preserve substantially intact its
business organization, maintain its material rights and franchises, retain the
services of its respective officers and IN employees and maintain its
relationships with its material customers and suppliers;

          (3) maintain and keep its material properties and assets in as good
repair and condition as at present, ordinary wear and tear excepted, and
maintain supplies and inventories in quantities consistent with its customary
business practice;

          (4) use all reasonable efforts to keep in full force and effect
insurance 

                                      -36-
<PAGE>
 
and bonds comparable in amount and scope of coverage to that currently
maintained;

          (5) take all such steps as are commercially reasonable in order to
consummate the Merger and all other transactions contemplated hereby, including,
without limitation, securing all requisite consents thereto.


     SECTION 1.61.  Access and Information.
                    ---------------------- 

          (1) Except for HVE's proprietary product and customer databases,  HVE
shall afford IN and its officers, directors, employees, accountants,
consultants, legal counsel, agents and other representatives (collectively, the
"IN Representatives") reasonable access at reasonable times, upon reasonable
prior notice, to the officers, employees, agents, properties, offices and other
facilities of HVE and to the books and records thereof and  furnish promptly to
IN and the IN Representatives such information concerning the business,
properties, contracts, records and personnel of HVE (including, without
limitation, financial, operating and other data and information) as may be
reasonably requested, from time to time, by IN or such Representatives.

          (2) IN shall (i) afford to HVE and its officers, directors, employees,
accountants, consultants, legal counsel, agents and other representatives
(collectively, the "HVE Representatives") reasonable access at reasonable times,
upon reasonable prior notice, to the officers, employees, accountants, agents,
properties, offices and other facilities of IN and to its books and records and
(ii) furnish promptly to HVE and HVE Representatives such information concerning
the business, properties, contracts, records and personnel of IN (including,
without limitation, financial, operating and other data and information) as may
be reasonably requested, from time to time, by HVE or such Representatives.

          (3) Notwithstanding the foregoing provisions of this Section 5.05,
neither party shall be required to grant access or furnish information to the
other party to the extent that such access to or the furnishing of such
information is prohibited by Law.  No investigation by the parties hereto made
heretofore or hereafter shall affect the representations and warranties of the
parties which are herein contained and each such representation and warranty
shall survive such investigation.

          (4) Each of the parties hereto will treat and hold as confidential any
information ("Confidential Information") concerning the business and affairs of
IN or HVE that is not already generally available to the public, refrain from
using any of the Confidential Information except in connection with this
Agreement, and deliver promptly to the party providing such information or
destroy, at the request and option of such party, all tangible embodiments (and
all copies) of the Confidential Information which are in his or its possession.
In the event that any party hereto is requested or required (by oral question or
request for information or documents in any legal proceeding, interrogatory,
subpoena, civil investigative demand, or similar process) to disclose any
Confidential Information, such person will notify the other parties promptly of
the request or requirement so that the other parties may seek an appropriate
protective order or waive compliance 

                                      -37-
<PAGE>
 
with the provisions of this Section 5.05 (d). If, in the absence of a protective
order or the receipt of a waiver hereunder, any party hereto is, on the advice
of counsel, compelled to disclose any Confidential Information to any tribunal
or else stand liable for contempt, such person may disclose the Confidential
Information to the tribunal; provided, however, that the disclosing person shall
                             --------  -------
use his or its best efforts to obtain, at the request of the other parties, an
order or other assurance that confidential treatment will be accorded to such
portion of the Confidential Information required to be disclosed as the other
parties shall designate. The foregoing provisions shall not apply to any
Confidential Information which is generally available to the public immediately
prior to the time of disclosure.


                                   ARTICLE VI

                             ADDITIONAL AGREEMENTS

     SECTION 1.62.  Stockholder Approval.
                    -------------------- 

          HVE shall, promptly after the date hereof, take all actions necessary
in accordance with California Law, and its articles of incorporation and bylaws
to solicit written consents of stockholders, to act on this Agreement.  HVE
shall solicit from stockholders of HVE written consents in favor of the approval
and adoption of this Agreement required by California Law and its articles of
incorporation and bylaws to approve and adopt this Agreement, the Merger and the
consummation of the transactions contemplated hereby.

     SECTION 1.63.  Registration Statement; Information.
                    ----------------------------------- 

          (1) If at any time IN proposes to register any of its Common Stock
under the Securities Act for sale to the public (such sale being hereinafter
referred to as a "Public Offering"), except with respect to registration
statements on Forms S-4, S-8 or their then equivalents, until such time as the
Merger Consideration shall become transferable under the Securities Act pursuant
to Rule 144 promulgated thereunder, IN shall  give written notice to each
Selling Shareholder of its intention to do so.  Upon the written request of any
Selling Shareholder, received by IN within thirty (30) days after the giving of
any such notice by IN to include in the registration statement with respect to
such Public Offering (each, a "Piggyback Registration Statement") any of his
Merger Consideration (which request shall state the intended method of
disposition thereof), IN shall use its best efforts to cause such shares to be
included in the securities to be sold in such Public Offering, all to the extent
requisite to permit the sale or other disposition by each requesting Selling
Shareholder (in accordance with his written request) of his shares.

          (2) Once and only once, as promptly as practicable after the receipt
of a written demand from a majority in number of the Selling Shareholders
(provided they continue to hold beneficially at least 70,000 issued and
outstanding shares of IN Common Stock and such shares are not freely
transferable under Rule 144 without any discount in price due to the volume or
other 

                                      -38-
<PAGE>
 
limitations imposed by such Rule), IN shall prepare and file with the
Commission a registration statement on Form S-1, S-2 or S-3, or their then
equivalent (the "Demand Registration Statement", and together with any Piggyback
Registration Statements, the "Registration Statements")  registering the shares
of IN Common Stock issued in connection with the Merger.   IN shall use its best
efforts to cause such Demand Registration Statement to be declared effective by
the Commission as promptly as practicable.

          (3) IN shall furnish each Selling Shareholders whose shares are being
registered on any Registration Statement with a reasonable number of copies of
the prospectus included in such Registration Statement for use in connection
with any sales of his shares as soon as practicable after such Registration
Statement is declared effective by the Commission.  IN agrees to bear all of the
costs associated with the preparation and filing of any Registration Statement,
including all filing fees, legal, accounting and printing costs but shall not be
required to pay the legal or accounting costs or underwriting fees and expenses,
if any, incurred by any Selling Shareholder.  If a Demand Registration Statement
is on Form S-1 or S-2, IN shall prepare and file with the Commission all Post-
Effective Amendments necessary to keep such Registration Statement current for
the period ending on the earlier of (i) the sale of all the shares of IN Common
Stock included in such Registration Statement or (ii) the second anniversary of
the Effective Time.  The inclusion of any Selling Shareholders  shares of IN
Common Stock in any Registration Statement shall be contingent upon the receipt
from such Selling Shareholder of all such information required to be disclosed
in the Registration Statement under the Securities Act by the Selling
Shareholder pursuant to applicable rules and regulations promulgated by the
Commission.

          (4) IN hereby represents and warrants to each Selling Shareholder that
the information contained in any Registration Statement including Merger
Consideration (other than information to be furnished by the Selling
Shareholders) shall not, at the time the Registration Statement is declared
effective by the Commission mailed to IN stockholders contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.  All documents
that IN is responsible for filing with the Commission in connection with the
transactions contemplated herein shall comply as to form in all material
respects with the applicable requirements of the Securities Act and the rules
and regulations thereunder and the Exchange Act and the rules and regulations
thereunder.

          (5) Each Selling Shareholder represents and warrants to IN that the
information to be supplied by such  Selling Shareholder for inclusion any
Registration Statement shall not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading.

          (6) If any offering of IN Common Stock pursuant to a Registration
Statement is an underwritten public offering and the managing underwriter
determines in good faith and advises IN in writing that the number of shares of
IN Common Stock which IN proposes to offer 

                                      -39-
<PAGE>
 
under such Registration Statement, together with the Merger Consideration and
other shares of Common Stock requested to be included in such Registration
Statement by the holders of securities having registration rights similar to
those of this Section 6.02, exceeds the number of shares of equity securities it
is advisable to offer and sell at such time, then the number of shares to be
sold by IN, each Selling Shareholder and such other shareholders shall be
reduced pro-rata; provided that the number of shares to be sold by IN, each
requesting Selling Shareholder and such other shareholders after such reduction
shall be allocated among IN, each requesting Selling Shareholder and such other
shareholders such that IN shall have the right to have offered no less than 75%
of the original number of shares proposed or requested by IN to be registered.
Notwithstanding the foregoing provisions, IN may withdraw any Piggyback
Registration Statement referred to in this Section 6.02 without thereby
incurring any liability to any Selling Shareholder provided that IN withdraws
the entire registration statement to which such Piggyback Registration Statement
relates.

     SECTION 1.64.  Appropriate Action; Consents; Filings; Indemnification.
                    ------------------------------------------------------ 

          (1) HVE and IN shall each use all reasonable efforts to (i) take, or
cause to be taken, all appropriate action, and do, or cause to be done, all
things necessary, proper or advisable under applicable Law or otherwise to
consummate and make effective the transactions contemplated by this Agreement,
(ii) obtain from any Governmental Entities any consents, licenses, permits,
waivers, approvals, authorizations or orders required to be obtained or made by
IN or HVE in connection with the authorization, execution and delivery of this
Agreement and the consummation of the transactions contemplated hereby,
including, without limitation, the Merger, (iii) make all necessary filings, and
thereafter make any other required submissions, with respect to this Agreement
and the Merger required under (A) the Securities Act and the Exchange Act and
the rules and regulations thereunder, and any other applicable federal or state
securities laws, and (B) any other applicable Law; provided that IN and HVE
shall cooperate with each other in connection with the making of all such
filings, including providing copies of all such documents to the nonfiling party
and its advisors prior to such filings and, if requested, shall accept all
reasonable additions, deletions or changes suggested in connection therewith.
HVE and IN shall furnish all information required for any application or other
filing to be made pursuant to the rules and regulations of any applicable Law
(including, without limitation, all information required to be included in the
Registration Statement) in connection with the transactions contemplated by this
Agreement.

          (2) IN and HVE agree to cooperate with respect to, and shall  cause
each of their respective subsidiaries to cooperate with respect to, and agree to
use all reasonable efforts vigorously to contest and resist, any action,
including legislative, administrative or judicial action, and to have vacated,
lifted, reversed or overturned any decree, judgment, injunction or other order
(whether temporary, preliminary or permanent) (an "Order") of any Governmental
Entity that is in effect and that restricts, prevents or prohibits the
consummation of the Merger or any other transactions contemplated by this
Agreement, including, without limitation, by vigorously pursuing all available
avenues of administrative and  judicial appeal and all available legislative
action.  Each of IN and HVE also agree to take any and all actions, including,
without limitation, the disposition of assets or the withdrawal from doing
business in particular jurisdictions, required 

                                      -40-
<PAGE>
 
by regulatory authorities as a condition to the granting of any approvals
required in order to permit the consummation of the Merger or as may be required
to avoid, lift, vacate or reverse any legislative or judicial action which would
otherwise cause any condition to Closing not to be satisfied; provided, however,
that in no event shall IN be required to take any action that would or could
reasonably be expected to have a IN Material Adverse Effect, and HVE shall not
be required to take any action which would or could reasonably be expected to
have an HVE Material Adverse Effect.

          (3) Each of IN and HVE shall promptly notify the other of (w) any
material change in its current or future business, assets, liabilities,
financial condition or results of operations, (x) any complaints, investigations
or hearings (or communications indicating that the same may be contemplated) of
any Governmental Entities with respect to its business or the transactions
contemplated hereby, (y) the institution or the threat of material litigation
involving it or any of its subsidiaries or (z) any event or condition that might
reasonably be expected to cause any of its representations, warranties,
covenants or agreements set forth herein not to be true and correct at the
Effective Time.  As used in the preceding sentence, "material litigation" means
any case, arbitration or adversary proceeding or other matter which would have
been required to be disclosed on the HVE Disclosure Schedule pursuant to Section
3.09 or the IN Disclosure Schedule pursuant to Section 4.09, as the case may be,
if in existence on the date hereof, or in respect of which the legal fees and
other costs  to HVE might reasonably be expected to exceed $10,000 over the life
of the matter or  to IN (or its subsidiaries) might reasonably be expected to
exceed $10,000 over the life of the matter.

          (4) In the event of any threatened, pending or completed claim,
action, suit, investigation or any legal, administrative or other proceeding
("proceeding") by any governmental entity or other person which questions the
validity or legality of the transactions contemplated by this Agreement or seeks
to enjoin, restrain or prohibit such transactions, or seeks damages in
connection therewith, whether before or after the Effective Time of the Merger,
IN and IN agree, to the fullest extent permissible by law, to vigorously defend
and respond thereto.

     SECTION 1.65.  Tax and Accounting Treatment.  Each party hereto shall use
                    ----------------------------                              
all reasonable efforts to cause the Merger to qualify, and shall not take, and
shall use all reasonable efforts to prevent any affiliate of such party from
taking, any actions that could prevent the Merger from qualifying, as a
reorganization under the provisions of section 368(a) of the Code or from
qualifying for the "pooling of interests" method of accounting as provided in
APB 16.

     SECTION 1.66.  Public Announcements.  Neither party shall issue any press
                    --------------------                                      
release or otherwise make any public statements with respect to the Merger
without the approval of the other.

     SECTION 1.67.  No Interference.  Pending the Closing, neither party shall
                    ---------------                                           
take any action which would unreasonably be expected to interfere with the
business or operations of the other.

                                      -41-
<PAGE>
 
     SECTION 1.68.  Form D Filing.  At or immediately after the Closing, IN
                    -------------                                          
shall file with the Commission an appropriately completed, dated and executed
Form D reflecting the issuance of the Merger Consideration.

competent jurisdiction shall have enacted, issued, promulgated, enforced or

the grant of a regulatory approval necessary, in the reasonable business
judgment of IN, to the continuing operation of the current or future business of

              -----------------------                                          
shall have been no change, occurrence or circumstance in the current or future

          (4) Absence of Regulatory Conditions.  There shall not be any action
              --------------------------------                                
taken, or any statute, rule, regulation or order enacted, entered, enforced or

     SECTION 1.72.  Termination.  This Agreement may be terminated at any time
                    -----------

          (1)  by mutual consent of IN and HVE;

          (2) by IN, upon a material breach of any representation, warranty,
covenant or agreement on the part of HVE set forth in this Agreement, or if any
representation or warranty of HVE shall have become untrue, in either case such
that the conditions set forth in Section 7.02(a) or Section 7.02(b) of this
Agreement, as the case may be, would be incapable of being satisfied by February
28, 1999 (or as otherwise extended as described in Section 8.01(e)); provided,
that in any case, a wilful breach shall be deemed to cause such condition as to
be incapable of being satisfied for purposes of this Section 8.01(b);

          (3) by HVE, upon a material breach of any representation, warranty,
covenant or agreement on the part of IN set forth in this Agreement, or if any
representation or warranty of IN shall have become untrue, in either case such
that the conditions set forth in Section 7.03, (a) or Section 7.03(b) of this
Agreement, as the case may be, would be incapable of being satisfied by February
28, 1999 (or as otherwise extended as described in Section 8.01(e)); provided,
that in any case, a wilful breach shall be deemed to cause such conditions to be
incapable of being satisfied for purposes of Section 8.01(c);

          (4) by either IN or HVE, if there shall be any Order which is final
and nonappealable preventing the consummation of the Merger, except if the party
relying on such Order to terminate this Agreement has not complied with its
obligations under Section 6.03(b) of this Agreement;

          (5) by either IN or HVE, if the Merger shall not have been consummated
before February 28, 1999; provided, however, that this Agreement may be extended
by written notice of either IN or HVE to a date not later than March 15, 1999,
if the Merger shall not have been consummated as a direct result of HVE or IN
having failed by February 28, 1999 to receive all required regulatory approvals
or consents with respect to the Merger; or

          (6) by IN, if this Agreement and the Merger shall fail to be approved
and adopted by the requisite numbers of stockholders of HVE in accordance with
California Law.

          The right of any party hereto to terminate this Agreement pursuant to
this Section 8.01 shall remain operative and in full force and effect regardless
of any investigation made by or on behalf of any party hereto, any person
controlling any such party or any of their respective officers, directors,
representatives or agents, whether prior to or after the execution of this
Agreement.

     SECTION 1.73.  Effect of Termination.  Except as provided in Section 8.05
                    ---------------------                                     
or Article IX of this Agreement, in the event of the termination of this
Agreement pursuant to Section 8.01, this Agreement shall forthwith become void,
there shall be no liability on the part of IN or HVE to the other and all rights
and obligations of any party hereto shall cease, except that nothing herein
shall relieve any party of any liability for  any material breach of such
party's covenants or agreements contained in this Agreement, or  any willful
breach of such party's representations 

                                      -45-

or warranties contained in this Agreement.

     SECTION 1.74.  Amendment.  This Agreement may be amended by the parties
                    ---------                                               
hereto at any time prior to the Effective Time; provided, however, that, after
approval of the Merger by the stockholders of HVE,  no amendment, which under
applicable Law may not be made without the approval of the stockholders of HVE,
may be made without such approval.  This Agreement may not be amended except by
an instrument in writing signed by the parties hereto.

     SECTION 1.75.  Waiver.  At any time prior to the Effective Time, any party
                    ------                                                     
hereto may  extend the time for the performance of any of the obligations or
other acts of the other party hereto,  waive any inaccuracies in the
representations and warranties of the other party contained herein or in any
document delivered pursuant hereto and  waive compliance by the other party with
any of the agreements or conditions contained herein.  Any such extension or
waiver shall be valid only if set forth in an instrument in writing signed by
the party or parties to be bound thereby.

     SECTION 1.76.  Fees, Expenses and Other Payments.
                    --------------------------------- 

          (1) Except as provided in Section 8.05(c) of this Agreement, in the
event the Merger is not consummated all Expenses (as defined in paragraph (b) of
this Section 8.05) incurred by the parties hereto shall be borne solely and
entirely by the party that has incurred such Expenses.

          (2) "Expenses" as used in this Agreement shall include all out-of-
pocket expenses (including, without limitation, all fees and expenses of
counsel, accountants, investment bankers, experts and consultants to a party
hereto and its affiliates) incurred by a party or on its behalf in connection
with or related to the authorization, preparation, negotiation, execution and
performance of this Agreement, and all other matters related to the consummation
of the transactions contemplated hereby.

          (3) If the Merger is consummated, IN shall pay any sales or transfer
taxes payable with respect to the exchange and surrender of the HVE Shares.


                                   ARTICLE IX

                                INDEMNIFICATION

     SECTION 1.77.  Survival of Representations and Warranties.  Except to the
                    ------------------------------------------                
extent otherwise specified  herein to the contrary, the rights of the respective
parties hereto to enforce or assert a claim for breach of any of the
representations, warranties, covenants and agreements herein shall survive the
execution and delivery of this Agreement and the Closing hereunder and shall
thereafter terminate and expire with respect to any theretofore unasserted claim
by IN against any Selling Shareholder for indemnification pursuant to Section
9.02 hereof, or with respect to any 

                                      -46-
<PAGE>
 
theretofore unasserted claim by any Selling Shareholder against IN for
indemnification pursuant to Section 9.03 hereof, on the date which is twenty-
four (24) months after the Closing Date, except for the representations and
warranties contained in Sections 3.01, 3.02, 3.11, 3.12, 3.13, 3.14, 3.22, 4.11
and 4.24 and the provisions of Sections 5.05(d), 6.02, 8.02, 8.05 and this
Article IX, which shall survive and continue in full force and effect as
provided therein until the expiration of the applicable statute of limitation.
Notwithstanding the foregoing, the right to enforce or assert a claim for
damages for breach of any representation, warranty, covenant or agreement in
respect of which indemnity may be sought under Section 9.02 or 9.03 shall
survive the time at which it would otherwise terminate if notice of the
inaccuracy or breach thereof giving rise to such right to indemnity shall have
been given to the party against whom such indemnity may be sought prior to such
time. The right to indemnification, payment of Losses (as defined below) or
other remedy based on such representations, warranties, covenants and
obligations will not be affected by any investigation conducted with respect to,
or any knowledge acquired (or capable of being acquired) at any time, whether
before or after the execution and delivery of this Agreement on the Closing
Date, with respect to the accuracy or inaccuracy of or compliance with, any such
representation, warranty, covenant or obligation. The waiver of any condition
based on the accuracy of any representation or warranty, or on the performance
of or compliance with any covenant or obligation, will not affect the right to
indemnification, payment of Losses, or other remedy based on such
representations, warranties, covenants and obligations. In respect of any matter
for which indemnification may be claimed hereunder, no claim for indemnification
hereunder of less than $1,000 shall be made unless and until the aggregate
amount of such claims against IN or any Selling Shareholder exceeds $15,000, in
which case such aggregate amount, and any subsequent such claims, may be claimed
hereunder.

     SECTION 1.78.  Indemnification of IN.  (a) Subject to the provisions of
                    ---------------------                                   
Section 9.01, each Selling Shareholder (other than Barker, with respect to whom
the Indemnity provisions hereunder are limited to Barker's express
representaions in this Agreement) hereby agrees, individually with respect to
the representations with respect to the Selling Shareholders set forth in
Sections 3.03(c), 3.04, 3.05 and 3.22, and jointly and severally with respect to
all other representations and covenants, to indemnify and hold IN and its
officers, directors, employees, agents, attorneys and other representatives
(collectively, "Representatives"), stockholders and controlling persons harmless
against any and all damages, losses, settlement payments, liabilities,
judgments, penalties, interest, and reasonable costs and expenses (including,
without limitation, reasonable attorneys' fees and disbursements (collectively,
"Losses")) suffered, sustained, incurred or required to be paid by IN or its
Representatives, stockholders or controlling persons, and affiliates relating
to, arising, directly or indirectly, out of, or in connection with:

     (a) the claims of brokers or finders hired by or claiming to have been
hired by any Seller; or

     (b) the breach of any representation or warranty made by any Seller in this
Agreement either when made or as if such representation or warranty were made on
and as of the Closing Date (in each case, without giving effect to any
supplement to the Schedules  made after the date hereof), or breach of any
covenant or agreement of any Seller contained in this Agreement.

                                      -47-
<PAGE>
 
     (c) The remedies provided in this Section 9.02 shall not be exclusive of or
limit any other remedies that may be available to any Indemnified Party (as
defined below in Section 9.04).

Notwithstanding any other provision of this Agreement, the Indemnity obligations
of each of the Selling Shareholders shall be limited to the amount of Merger
Consideration actually received by such  Selling Shareholder.

     SECTION 1.79.  Indemnification of Sellers.  Subject to the provisions of
                    --------------------------                               
Section 9.01, IN hereby agrees to indemnify and hold each Selling Shareholder
and its Representatives harmless against any and all Losses suffered, sustained,
incurred or required to be paid by such Selling Shareholder and its
Representatives relating to, arising, directly or indirectly, out of, or in
connection with:

          (i) the claims of brokers or finders hired by or claiming to have been
hired by IN; or

          (ii) the breach by IN of any of its obligations under this agreement
or the breach by IN of any of the representations, warranties or covenants of IN
hereunder.

     SECTION 1.80.  Notice to Indemnifying Party.  Promptly after any Selling
                    ----------------------------                             
Shareholder or IN, as the case may be, (i) receives notice of any claim or the
commencement of any investigation, action or proceeding against any of them or
(ii) has knowledge of any claim, investigation, action or proceeding brought
against them, or of circumstances which are likely to give rise to any such
claim, investigation, action or proceeding, or rights to indemnification
hereunder, such party (the "Indemnified Party") shall, if a claim for
reimbursement or setoff with respect thereto is to be made against a party
hereto obligated to provide indemnification (the "Indemnifying Party") under
Section 9.02 or 9.03 above or Section 9.06 below, give the Indemnifying Party
written notice of such claim, threatened claim or circumstances or of the
commencement of such investigation, action or proceeding.  Such written notice
shall be given within thirty (30) days after receipt of written notice, or a
summons and complaint or other legal process, or within sixty (60) days after
receipt of knowledge of any other claim, investigation, action or proceeding or
of circumstances which are likely to give rise to any such claim, investigation,
action or proceeding or rights to indemnification hereunder.  The failure to so
notify the Indemnifying Party will not relieve the Indemnifying Party  of any
liability that it may have to any Indemnified Party hereunder, except to the
extent that the Indemnifying Party demonstrates that the defense of such action
is prejudiced by such failure by the Indemnifying Party to give such notice.

     SECTION 1.81.  Compromise of Claims.  (a) If a claim under this Article IX
                    --------------------                                       
involves a claim by a third party against the Indemnified Party, the
Indemnifying Party shall have thirty (30) days after receipt of written notice
thereof to decide whether the Indemnifying Party will undertake, conduct and
control, through counsel of its own choosing and at its own expense, the
settlement or defense thereof, and if it so decides, the Indemnified Party may
cooperate with it in connection therewith; provided, that the Indemnified Party
                                           --------                            
may participate in such settlement or defense 

                                      -48-
<PAGE>
 
through counsel chosen by it; and provided further, that the fees and expenses 
                                  -------- -------
of such counsel shall be borne by the Indemnified Party. If the Indemnifying
Party assumes the defense of a proceeding, (i) it will be conclusively
established for purposes of this Agreement that the claims made in that
proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the Indemnifying
Party without the Indemnified Party's consent, which shall not be unreasonably
withheld, unless (A) there is no finding or admission of any violation of law or
any violation of the rights of any person and no effect on any other claims that
may be made against the Indemnified Party, (B) the sole relief provided is
monetary damages and (C) such compromise or settlement does not contemplate or
result in any monetary damages that are to be paid by the Indemnified Party; and
(iii) the Indemnified Party will have no liability with respect to any
compromise or settlement of such claims effected without its consent. If notice
is given to an Indemnifying Party of the commencement of any proceeding and the
Indemnifying Party does not, within ten days after the Indemnifying Party's
notice is given, give notice to the Indemnified Party of its election to assume
the defense of such proceeding, the Indemnifying Party will be bound by any
determination made in such proceeding or any compromise or settlement effected
by the Indemnified Party.

          (b) The Indemnified Party shall cooperate fully in all aspects of any
investigation, defense, pretrial activities, trial, compromise, settlement or
discharge of any claim in respect of which indemnity is sought pursuant to this
Article IX, including, but not limited to, providing the other party with
reasonable access to physical facilities and offices, books and records and
employees and officers (including as witnesses) and other information.

          (c) Notwithstanding the foregoing, if an Indemnified Party determines
in good faith that there is a reasonable probability that a proceeding may
adversely affect it or its affiliates other than as a result of monetary damages
for which it would be entitled to indemnification under this Agreement, the
Indemnified Party may, by notice to the Indemnifying Party, assume the exclusive
right to defend, compromise or settle such proceeding, but the Indemnifying
Party will not be bound by any determination of a proceeding so defended or any
compromise or settlement effected without its consent (which shall not be
unreasonably withheld).

          (d) Each Indemnifying Party hereby consents to the non-exclusive
jurisdiction of any court in which a proceeding is brought by a third party
against any Indemnified Party for purposes of any claim that an Indemnified
Party may have under this Agreement with respect to such proceeding or the
matters alleged therein, and agrees that process may be served on such
Indemnifying Party with respect to such a claim anywhere in the world.

     SECTION 1.82.  Right of Set-Off.  Upon notice to the Selling Shareholders
                    ----------------                                          
specifying in reasonable detail the basis for such set-off, IN may set off any
amount to which it may be entitled under this Article IX against amounts
otherwise payable to any Selling Shareholder hereunder as Merger Compensation.
The exercise of such right of set-off by IN in good faith will not constitute a
breach of this Agreement.  In the event that IN shall exercise its right of set
off hereunder with respect to a portion of the Merger Consideration (the "Set-
Off Shares"), and it is finally determined by a court of competent jurisdiction
(including all appellate counts) that IN is not, in fact, entitled 

                                      -49-
<PAGE>
 
to the Set-Off Shares under this Article IX, then IN shall issue the Set-Off 
Shares to the Selling Shareholders, together with additional shares of IN Common
Stock in the amount equal to 10% of the amount of the Set-Off Shares, such
additional shares to serve as liquidated damages for the delay suffered by the
Selling Shareholders in receiving their Set-Off Shares. Neither the exercise of
nor the failure to exercise such right of set-off will constitute an election of
remedies or limit IN in any manner in the enforcement of any other remedies that
may be available to it; nor will the exercise, failure to exercise or existence
of IN's right hereunder to exercise such right of set-off prejudice in any way
the adjudication of the merits of any claim asserted by IN in any subsequent
proceeding. Nothing contained herein shall prevent the Selling Shareholders from
seeking or obtaining all of their damages from IN as a result of the wrongful
set-off by IN of the Set-Off Shares.
