ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

   On February 1, 1996, the Registrant ("IRIS") and Norfolk Scientific, Inc.,
d/b/a StatSpin Technologies, ("StatSpin") effected a combination of their
respective businesses through a merger of StatSpin Acquisition Corporation, a
newly-formed Massachusetts corporation and wholly-owned subsidiary of IRIS
("Merger Sub"), with and into StatSpin, with StatSpin being the surviving
corporation and becoming a wholly-owned subsidiary of IRIS (the "Merger").

   StatSpin, based in Norwood, MA, manufactures special purpose centrifuges and
other small instruments widely used in clinical, veterinary, physician's office
and research laboratories and distributes its products primarily through the
Curtin Matheson Scientific Division of Fisher Scientific and a number of leading
distributors to the physician's office and veterinary laboratories markets.
StatSpin had net sales of $2.9 million in its last fiscal year.

   IRIS completed the acquisition of StatSpin for approximately 340,000 shares
of IRIS common stock and the assumption of options and warrants to purchase an
additional 126,000 shares of IRIS common stock.  The total consideration paid by
IRIS is valued at $3,000,000 based on a value of $7.58 per share of IRIS common
stock which was the average closing price for the ten-day period ending on
January 26, 1996.  The acquisition is expected to qualify as a pooling-of-
interests for financial accounting purposes.

   IRIS plans to continue current StatSpin operations as well as its channels of
distribution with StatSpin operating as an IRIS subsidiary.  Dr. Thomas F.
Kelley, StatSpin founder and chief executive, will be the General Manager of the
new subsidiary and also will become a member of the IRIS Board of Directors.

INC., a Delaware corporation ("IRIS"), NORFOLK SCIENTIFIC, INC., a Massachusetts

     B.   The Boards of Directors of IRIS and StatSpin believe it is in the best
interests of each company and their respective stockholders to consummate such

Merger shall become effective (the "EFFECTIVE TIME") upon the filing of the
Articles of Merger.

     1.4  ARTICLES OF ORGANIZATION; BY-LAWS.  The Articles of Organization and
By-Laws of Merger Sub, as in effect immediately prior to the Effective Time and
as amended by the Articles of Merger, shall become the Articles of Organization
and By-Laws of the Surviving Corporation and thereafter shall continue in effect
until amended as provided therein and in the Massachusetts Business Corporation
Law.

     1.5  DIRECTORS AND OFFICERS.  The directors and officers of Merger Sub
immediately prior to the Effective Time shall become the directors and officers
of the Surviving Corporation and shall hold office from the Effective Time until
their respective successors are duly elected or appointed and qualified in the
manner provided in the By-Laws of the Surviving Corporation, or as otherwise
provided by law.

     1.6  CONVERSION OF CAPITAL STOCK.  At the Effective Time and subject to the
provisions of Sections 1.9 (Escrow of Shares) and 1.10 (Maximum Merger
Consideration), by virtue of the Merger and without any action on the part of
IRIS, StatSpin, Merger Sub or any stockholder of StatSpin:

          1.6.1  CONVERSION OF OUTSTANDING STATSPIN STOCK.  Each share of
StatSpin Common Stock issued and outstanding immediately prior to the Effective
Time, other than shares held by StatSpin as treasury stock and shares held by

into the right to receive 4.0950 shares of IRIS Common Stock (the "EXCHANGE
RATIO").

          1.6.2  CANCELLATION OF STATSPIN TREASURY SHARES.  Each Share held by
StatSpin as treasury stock immediately prior to the Effective Time shall be
cancelled and extinguished at the Effective Time without any conversion thereof
and no payment shall be made with respect thereto.

          1.6.3  CONVERSION OF MERGER SUB STOCK.  Each share of common stock,

<PAGE>

transfer agent for IRIS, together with a duly executed letter of transmittal or
affidavit of loss and such other documents as may be reasonably requested by
IRIS or the transfer agent (including, without limitation, an indemnification
agreement with respect to lost certificates), and shall thereupon be entitled to
receive in exchange therefor a certificate or certificates representing the
number of whole shares of IRIS Common Stock into which the shares so surrendered
shall have been converted.  No fractional shares shall be issued, but in lieu
thereof holders of certificates who would otherwise be entitled to receive a
fraction of a share of IRIS Common Stock shall be paid an amount in cash equal
to the value of such fraction of a share based upon the IRIS Stock Price.  The
fractional share interests of each holder shall be aggregated so that no holder
receives cash in an amount equal to or greater than the value of one full share
of IRIS Common Stock.  Until so surrendered, each certificate which, prior to
the Effective Time, represented shares of StatSpin Common Stock shall, from and
after the Effective Time, represent only the right to receive shares of IRIS
Common Stock and cash in lieu of any fractional interests.  Neither IRIS, its
transfer agent, Merger Sub, StatSpin or the Surviving Corporation shall be
liable to any holder of such certificates for any cash or shares of IRIS Common
Stock properly paid to a public official pursuant to applicable abandoned
property, escheat or similar law.

     1.7  CONVERSION OF STOCK APPRECIATION RIGHTS.  At the Effective Time and
subject to (A) applicable federal and state withholding requirements, (B) the
provisions of Section 1.9 (Escrow of Shares) and (C) the provisions of
Section 1.10 (Maximum Merger Consideration), IRIS shall issue as satisfaction in
full for each StatSpin SAR issued and outstanding immediately prior to the
Effective Time the number of shares of IRIS Common Stock determined in
accordance with this Section 1.7.

          1.7.1  UNCAPPED STATSPIN SAR'S.  With respect to each holder of a
StatSpin SAR on the Effective Date which is not subject to an SAR Cap, IRIS
shall issue a number of shares of IRIS Common Stock equal to (A) the number of
shares of StatSpin Common Stock with respect to which such holder's StatSpin SAR
has vested MULTIPLIED BY (B) the difference between the StatSpin Stock Price and
the base price of such StatSpin SAR (i.e. the "spread") DIVIDED BY (C) the IRIS
Stock Price.

          1.7.2  CAPPED STATSPIN SAR'S.  With respect to each holder on the
Effective Date of a StatSpin SAR subject to an SAR Cap, IRIS shall issue a
number of shares of IRIS Common Stock equal to (A) the number of shares of
StatSpin Common Stock with respect to which such holder's StatSpin SAR has
vested MULTIPLIED BY (B) the difference between the SAR Cap and the base price
of such StatSpin SAR (i.e. the "spread") DIVIDED BY (C) the IRIS Stock Price.

          1.7.3  EXCHANGE OF AGREEMENTS; FRACTIONAL SHARES.  As soon as
practicable after the Effective Time, each holder of an outstanding agreement
that prior thereto represented a StatSpin SAR shall surrender such agreement to
the transfer agent for IRIS, together with a duly executed letter of transmittal
or affidavit of loss and such other documents as may be reasonably requested by
IRIS or the transfer agent (including, without limitation, an indemnification
agreement with respect to lost

                                       -3-

<PAGE>

certificates), and shall thereupon, subject to applicable federal and state
withholding requirements, be entitled to receive in exchange therefor a
certificate or certificates representing the number of whole shares of IRIS
Common Stock into which the StatSpin SAR agreement so surrendered shall have
been converted.  No fractional shares shall be issued, but in lieu thereof
holders of StatSpin SAR agreements who would otherwise be entitled to receive a
fraction of a share of IRIS Common Stock shall be paid an amount in cash equal
to the value of such fraction of a share based upon the IRIS Stock Price.  The
fractional share interests of each holder shall be aggregated so that no holder
receives cash in an amount equal to or greater than the value of one full share
of IRIS Common Stock.  Until so surrendered, each agreement which, prior to the
Effective Time, represented a StatSpin SAR shall, from and after the Effective
Time, represent only the right to receive shares of IRIS Common Stock and cash
in lieu of any fractional interests.  Neither IRIS, its transfer agent, Merger
Sub, StatSpin or the Surviving Corporation shall be liable to any holder of such
StatSpin SAR for any cash or shares of IRIS Common Stock properly paid to a
public official pursuant to applicable abandoned property, escheat or similar
law.

     1.8  ASSUMPTION OF WARRANTS AND STOCK OPTIONS.  At the Effective Time and
subject to the provisions of Section 1.10 (Maximum Merger Consideration), IRIS
shall assume each outstanding warrant (a "STATSPIN WARRANT"), and each
outstanding option, whether vested or unvested, (a "STATSPIN OPTION"), to
purchase shares of StatSpin Common Stock.  From and after the Effective Time,
each outstanding StatSpin Warrant and each outstanding StatSpin Option shall
entitle the holder to purchase shares of IRIS Common Stock on the same terms and
conditions as set forth in such StatSpin Warrant or StatSpin Option (including,
without limitation, any applicable vesting schedule), EXCEPT THAT (i) the holder
shall be entitled to purchase the number, rounded down to the nearest whole
integer, of full shares of IRIS Common Stock such holder would have been
entitled to receive pursuant to the Merger had such holder exercised such
StatSpin Warrant or StatSpin Option in full, including as to unvested shares,
immediately prior to the Effective Time, (ii) the price per share of IRIS Common
Stock shall be an amount, rounded up to the nearest whole cent, equal to (A) the
exercise price per share for the shares of StatSpin Common Stock otherwise
purchasable pursuant to the StatSpin Warrant or StatSpin Option DIVIDED BY
(B) the Exchange Ratio, and (iii) the registration rights of the holder shall be
as set forth in the Registration Rights Agreement which shall supersede any
registration rights previously associated with or contained in such holders
StatSpin Option or StatSpin Warrant.  As soon as practicable after the Effective
Time, upon receipt by IRIS of a copy of such StatSpin Warrant or StatSpin
Option, IRIS issue and deliver to the holder thereof an originally signed
agreement evidencing the foregoing assumption of such StatSpin Warrant or
StatSpin Option by IRIS.

     1.9  ESCROW OF SHARES.  At the Closing, the holders of record of StatSpin
Common Stock at the Effective Time and the holders of record of StatSpin SAR's
at the Effective Time shall deposit in escrow ten percent (10%) of the aggregate
number of shares of IRIS Common Stock received by them in connection with the
Merger (the "ESCROWED SHARES").  For purposes of creating such escrow, each
holder of record of at the Effective Time of StatSpin Common Stock and each
holder of record at the Effective

                                       -4-


<PAGE>

Time of StatSpin SAR's shall contribute a pro rata number of the shares of IRIS
Common Stock based on the number of shares of IRIS Common Stock to which all
such holders are entitled at the Effective Time.  Subject to compliance with the
provisions of Sections 1.6.4 (Exchange of Stock Certificates) and 1.7.3
(Exchange of StatSpin SAR Agreements), as applicable, the Escrowed Shares shall
be released in accordance with the terms of the Escrow Agreement to the holders
of record at the Effective Time of StatSpin Common Stock and the holders or
record at the Effective Time of StatSpin SAR's pro rata based on the number of
shares of IRIS Common Stock to which each holder was entitled at the Effective
Time.  The escrow shall be administered in accordance with the terms of the
Escrow Agreement.  The parties agree that for federal income tax purposes, the
holders of record at the Effective Time of StatSpin Common Stock and the holders
of record at the Effective Time of StatSpin SAR's will own the Escrowed Shares
as of the Effective Time.

     1.10 MAXIMUM MERGER CONSIDERATION.  The parties acknowledge that the
Exchange Ratio was based on an exchange of $3,000,000 of IRIS Common Stock for
all of the outstanding StatSpin Common Stock, StatSpin SAR's, StatSpin Warrants
and StatSpin Options.  Therefore, the parties agree that the maximum
consideration to be paid by IRIS (including IRIS Common Stock to be reserved for
issuance upon exercise of StatSpin Options and StatSpin Warrants assumed by
IRIS) pursuant to the Merger shall be limited to a number of shares of IRIS
Common Stock equal to $3,000,000 plus the aggregate exercise price of the
outstanding StatSpin Options and StatSpin Warrants divided by the IRIS Stock
Price.  In the event that the outstanding StatSpin Common Stock, StatSpin SAR's,
StatSpin Warrants and StatSpin Options at the Effective Time is greater as set
forth on SCHEDULES 2.4(A) AND 2.4(B), the Exchange Ratio shall be
proportionately decreased.  No adjustment shall be made in the aggregate
consideration to be paid in the Merger as a result of any cash proceeds received
by StatSpin pursuant to the exercise of currently outstanding StatSpin Warrants
or StatSpin Options.

     1.11 TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after the
Effective Time, any such further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of StatSpin and Merger Sub, the officers and directors of
StatSpin and Merger Sub are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action.

     1.12 REGISTRATION RIGHTS.  The shares of IRIS Common Stock issued to
holders of StatSpin Common Stock and holders of StatSpin SAR's in connection
with the Merger, and the shares of IRIS Common Stock issuable upon exercise to
holders of StatSpin Warrants and StatSpin Options assumed by IRIS in connection
with the Merger, shall have the registration rights set forth in the
Registration Rights Agreement.

     1.13 LEGEND.  Each certificate for IRIS Common Stock issued hereunder or
under any StatSpin Warrant or StatSpin Option assumed hereunder, and each
certificate

                                       -5-

<PAGE>

issued in exchange or upon transfer of any thereof, shall be stamped or
otherwise imprinted with a legend in substantially the following form:

     The securities represented by this certificate have not been
     registered under the Securities Act of 1933, as amended, or qualified
     under any applicable state securities laws and may not be transferred,
     sold, assigned, pledged or otherwise disposed of unless (i) a
     registration statement under the Securities Act of 1933, as amended,
     shall have become effective with respect thereto and all applicable
     qualifications under state securities laws have been obtained with
     respect thereto, (ii) or a written opinion from counsel for the holder
     reasonably satisfactory to the issuer has been obtained stating that
     no such registration or qualification is required.


                                    SECTION 2

                   REPRESENTATIONS AND WARRANTIES OF STATSPIN

for the disposal of, any waste or Hazardous Materials to any location which is

accounting principles consistently applied (except as may be indicated in the
notes thereto or, in the case of unaudited statements, as permitted by Form 10-Q
of the SEC), fairly present the consolidated financial position of IRIS at the
dates thereof and of its operations and cash flows for the periods then ended

in the SEC Filings or the Offering Memorandum.  The IRIS press release dated
November 15, 1995 announcing the development program with Poly U/A Systems, Inc.
and the completion of a related unit offering is true and correct in all
material respects.

                                COVENANTS OF IRIS

     5.1  REPRESENTATIONS TRUE.  Until the Effective Time, IRIS will use its
best efforts to prevent the occurrence of any event which would cause any of its
representations and warranties set forth in this Agreement not to be true and
correct in any material respect.

     5.2  CONSENTS.  As promptly as practicable after the date of this
Agreement, IRIS shall effect all filings, registrations and requests for consent
with, and use reasonable efforts to obtain all consents, authorizations,
approvals and declarations from, all third parties and government agencies

party for IRIS or Merger Sub to consummate the Transactions other than the
filing of a registration statement under the Securities Act or any similar
filing with any state agency under the securities or "blue sky" laws of any
state.  StatSpin shall use reasonable efforts to assist IRIS as reasonably
requested with all matters described above in this Section 5.2.

     5.3  OFFERING MEMORANDUM.  As soon as practicable, IRIS shall prepare and
deliver to StatSpin an Offering Memorandum (the "OFFERING MEMORANDUM") in form
and substance satisfactory to StatSpin and IRIS describing IRIS, StatSpin and
the Transactions.

     5.4  LEGAL OPINION.  IRIS shall use reasonable efforts to cause Irell &
Manella, counsel for IRIS and Merger Sub, to render an opinion at the Closing,
dated as of the Closing Date, in substantially the form attached hereto as
EXHIBIT B.

     5.5  BENEFIT PLANS.  IRIS agrees to provide employees of StatSpin with
credit for all prior service with StatSpin for purposes of vesting and
eligibility under any employee benefit plan, program or arrangement of IRIS and
to enroll the Statspin employees in such employee benefit plans, programs and
arrangements (including, without limitation, enrolling qualified employees in
the IRIS Key Employee Stock Purchase Program) as soon as practicable after the
Effective Time; PROVIDED, HOWEVER, IRIS shall continue StatSpin's current health
plan absent a significant increase in the cost thereof.  Commencing three months
after the Effective Date, the senior management of the StatSpin will be eligible
for consideration for stock option awards under the 1994 IRIS Stock Option Plan
consistent with the Compensation Committee's general practices and policies.

     5.6  INDEMNIFICATION OF STATSPIN DIRECTORS AND OFFICERS.  The Articles of
Organization and Bylaws of the Surviving Corporation shall contain provisions
identical with respect to exculpation and indemnification to those set forth in
Article X of the Articles of Organization of StatSpin and Article V of the
Bylaws of StatSpin, respectively, which provisions shall not be amended,
repealed or otherwise modified for a period of six (6) years from the Effective
Time in any manner that would adversely

                                      -22-

<PAGE>

affect the rights thereunder of the individuals who were directors or officers
of StatSpin at the Effective Time.  The parties acknowledge that, in the event
of a merger of the Surviving Corporation with and into IRIS, the assumption by
IRIS of such indemnification obligations would not adversely affect the rights
of such directors and officers.

     5.7  TAX COMPLIANCE, REPORTING AND OTHER ACTIONS.  The parties acknowledge
that the Merger is intended to qualify as a reorganization within the meaning of
Section 368(a) of the Code.  Accordingly, IRIS shall comply with, and shall
cause Merger Sub and the Surviving Corporation to comply with, the reporting
requirements set forth in Treasury Regulation Section 1.368-3 applicable to them
with respect to the Merger Acquisition, and none of them shall make any election
or take any reporting or other position inconsistent with the treatment of the
Merger as a reorganization within the meaning of Section 368(a) of the Code
except as required by law.  Further, IRIS, Merger Sub and/or the Surviving
Corporation shall not take any action, or fail to take any action, which would
disqualify the Merger as a tax free reorganization under Section 368(a) of the
Code.  Without limiting the foregoing, IRIS shall cause the Surviving
Corporation to satisfy the "continuity of business enterprise" requirement as
provided in Section 1.368-(1)(d) of the Treasury Regulations, and IRIS will not
transfer the stock, and the Surviving Corporation will not transfer the assets,
of the Surviving Corporation in a manner which would disqualify the Merger as a
tax free reorganization under Section 368(a) of the Code.

     5.8  APPOINTMENT OF MR. KELLEY TO IRIS BOARD.  Promptly upon consummation
of the Merger, IRIS shall appoint Thomas F. Kelley to the IRIS Board of
Directors as a Class 3 Director and thereafter nominate Mr. Kelley for
reelection at the 1996 Annual Meeting of the IRIS stockholders.

under this Section 7.1 only if the Merger is consummated and only to the extent

otherwise have on account of this indemnity, except to the extent that the
Indemnifying Party has been materially prejudiced by such failure to notify.
The Indemnifying Party shall undertake full responsibility for the defense of
any Third-Party Claim which, if successful, would result in an obligation of
indemnity under this Section 7.  The Indemnifying Party may contest or settle
any such claim on such terms as the Indemnifying Party may choose, PROVIDED that
the Indemnifying Party will not have the right, without the Indemnified Party's
prior written consent, to settle any

                                      -27-

<PAGE>

such claim if such settlement (i) arises from or is part of any criminal action,
suit or proceeding, (ii) contains a stipulation to, confession of judgement with
respect to, or admission or acknowledgement of, any liability or wrongdoing on
the part of the Indemnified Party, (iii) relates to any Tax matters,
(iv) provides for injunctive relief, or other relief or finding other than money
damages, which is binding on the Indemnified Party, or (v) does not contain an
unconditional release of the Indemnified Party.  Such defense will be conducted
by reputable attorneys retained by the Indemnifying Party at the Indemnifying
Party's cost and expense, but the Indemnified Party will have the right to
participate in such proceedings and to be separately represented by attorneys of
its own choosing.  The Indemnified Party will be responsible for the costs of
such separate representation unless the Indemnified Party will have reasonably
concluded that the interests of the Indemnified Party and the Indemnifying Party
in the action conflict in such a manner and to such an extent as to make
advisable, consistent with applicable standards of professional responsibility,
the retention of separate counsel for the Indemnified Party, in which case the
Indemnifying Party will pay for one (but not more than one) separate counsel
chosen by the Indemnified Party.

     7.7  FAILURE TO ASSUME DEFENSE.  In the event that the Indemnifying Party,
by the 30th day after receipt of notice of any asserted claim (or, if earlier,
by the tenth day preceding the day on which an answer or other pleading must be
served in order to prevent judgment by default in favor of the person asserting
such claim), fails to assume the defense of such claim, the Indemnified Party
will (upon further notice to the Indemnifying Party) have the right to undertake
the defense, compromise or settlement of such claim on behalf of and for the
account and risk of the Indemnifying Party, subject to the right of the
Indemnifying Party to assume the defense of such claim at any time prior to
settlement, compromise or final determination thereof.  The result of any such
defense, compromise or settlement executed by the Indemnified Party in good
faith shall be binding upon the Indemnifying Party with respect to its
obligations of indemnity under this Section 7.

     7.8  COOPERATION.  The Indemnifying Party and the Indemnified Party shall
cooperate in determining the validity of any Third-Party Claim or Tax claim for
any Loss for which a claim of indemnification may be made hereunder.  Each party
shall also use all reasonable efforts to minimize all Losses.

     7.9  STOCKHOLDER REPRESENTATIVE.  The Stockholder Representative is hereby
appointed as agent and representative on behalf of the StatSpin Stockholders
with respect to any indemnification claims made hereunder and shall have full
authority to accept all notices, and consent to all settlements, on behalf of
the StatSpin Stockholders with respect to such claims.  IRIS shall, by delivery
of written notice to the Stockholder Representative but otherwise in accordance
with the applicable notice requirements, be deemed to have satisfied any
requirement to deliver notice hereunder or under the Escrow Agreement to the
StatSpin Stockholders or any subset thereof.

right to seek redress in another forum.  Each party shall bear the fees of the
arbitrator appointed by it, and the fees of

                                      -37-

the neutral arbitrators shall be borne equally by each party during the

consequence, the parties do not believe that the presumptions of California
Civil Code Section 1654 relating to the interpretation of contracts against the
drafter of any particular clause should be applied in this case and therefore
waive its effects.

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

                               INDEPENDENT AUDITORS' REPORT


The Board of Directors
Norfolk Scientific, Inc.:

We have audited the accompanying balance sheets of Norfolk Scientific, Inc.
as of March 31, 1995 and 1994, and the related statements of income and
accumulated deficit, and cash flows for the years then ended.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Norfolk Scientific, Inc. at
March  31, 1995 and 1994, and the results of its operations and its cash
flows for the years then ended, in conformity with generally accepted
accounting principles.

                           Notes to Financial Statements

                              March 31, 1995 and 1994


(1) NATURE OF BUSINESS

    Norfolk Scientific, Inc. (d/b/a StatSpin Technologies) (the "Company") was
      incorporated on June 11, 1984, as a successor to Kelley, Newhouse &
      Company, a partnership.  The Company purchased assets and rights from its
      predecessor to engage in the development, manufacture, and sale of
      medical and laboratory equipment and supplies.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (A) INVENTORIES
    Inventories are stated at the lower of cost or market, cost being determined
      using the first-in, first-out (FIFO) method.

    (B) PROPERTY AND EQUIPMENT
    Property and equipment is stated at cost.  Depreciation is provided using an
      accelerated method over the estimated useful lives of the respective
      assets.

    (C) OTHER ASSETS, NET
    Other assets consist principally of patents, stated at cost, net of
      accumulated amortization.  The cost of patents is amortized using the
      straight-line method over the estimated useful lives (five years) of the
      respective patents.

    (D) INCOME TAXES
    The Financial Accounting Standards Board has issued Statement 109,
      "Accounting for Income Taxes."  Statement 109 requires a change from the
      deferred method required under APB Opinion 11 to the asset and liability
      method.  Under the deferred method, annual income tax expense is matched
      with pretax accounting income by providing deferred taxes at current tax
      rates for timing differences between the determination of net income for
      financial reporting and tax purposes.  The objective of the asset and
      liability method is to establish deferred tax assets and liabilities for
      the temporary differences between the financial reporting basis and the
      tax basis of the Company's assets and liabilities at enacted tax rates
      expected to be in effect when such amounts are to be realized or settled.
      Under Statement 109, the effect on deferred tax assets and liabilities
      of change in tax rates is recognized in income in the period that includes
      the enactment date.

    Effective April 1, 1993, the Company adopted Statement 109.  The cumulative
      effect of the change in the method of accounting for income taxes is not
      material and therefore is not presented separately in the accompanying
      statements of operations and accumulated deficit for the year ended
      March 31, 1995.  Prior years' financial statements have not been restated
      to apply the provisions of Statement 109.

    (E) RECLASSIFICATIONS
    Certain reclassifications have been made to the fiscal 1994 financial
      statements to conform to the fiscal 1995 presentation.

                                                                   (Continued)

(3) RESTRICTED CASH

    The entire cash balance as of March 31, 1994 was restricted.  This cash
      was available for operating uses with the approval of Company's
      board of directors and the Massachusetts Technology Development
      Corporation ("MTDC").  During 1995, this restriction was removed in
      conjunction with the Company's restructuring of the debt due
      MTDC (see note 7).

(4) INVENTORIES

    Inventories consist of the following at March 31:

    Note payable to bank consists of borrowings under a $300,000 line of
      credit, expiring on September 30, 1995, that is secured by all of the
      assets of the Company. Under the line of credit the Company can borrow
      up to 75% of any of its accounts receivable balances, excluding those
      that have invoices outstanding for over 90 days. Interest is payable
      monthly at the bank's base rate plus 1.5% (9.5% and 8.25% at March 31,
      1995 and 1994, respectively).  The Company had $0 and $160,000 of

      in borrowings dated April 30, 1991, payable in 36 monthly installments
      of approximately $2,097, commencing May 1, 1993, and $150,000 in
      borrowings dated March 13, 1992, due on March 13, 1997.  Interest on
      the $75,500 note accrues on the unpaid principal balance at 11% and is
      payable monthly in arrears on the first day of each month starting
      November 1, 1991, with the first six months' interest having been
      deferred and paid in equal installments over the eighteen-month period
      commencing November 1, 1991. Interest on the $150,000 note accrues on
      the unpaid principal balance at 12% and is payable monthly in arrears
      on the first day of each month starting November 1, 1993, with the
      first eighteen months' interest having been deferred and paid in equal
      installments over the eighteen-month period commencing November 1,
      1993.  Interest expense for notes payable to stockholders for the years

                           Notes to Financial Statements


    Under the notes payable agreements, the Company is required to comply
      with various restrictive covenants.  As of March 31, 1995, the Company
      was not in compliance with certain covenants.  The Company has
      constructively received a waiver of such defaults as outlined in the
      note agreements as of March 31, 1995.

    In addition, 4,651 and 23,332 warrants, respectively, were issued to
      related parties in connection with the April 30, 1991 and March 13,
      1992 issuance of subordinated notes payable.  These warrants allow the
      holders to purchase 4,651 and 23,332 shares of the Company's common
      stock at $29.99 and $15.00 per share through April 30, 1996 and March
      13, 1997, respectively. No warrants have been exercised.

    During fiscal years 1995 and 1994, the Company performed product
      development and manufacturing activities for a stockholder of the
      Company.  Revenue for these sales and services amounted to $9,869 and
      $194,748 in fiscal years 1995 and 1994, respectively.

    Notes payable to MTDC totaling $166,660 and $373,605 at March 31, 1995 and
      1994, respectively, consist of unsecured subordinated borrowings, with
      interest payable monthly at rates ranging from 9% to 12%.  The notes
      consist of $250,000 in borrowings dated April 30, 1991, payable in 36
      monthly installments of approximately $6,944, commencing May 1, 1993,
      and $200,000 in borrowings dated March 13, 1992, due on March 13, 1997.
      Interest on the $250,000 note accrues on the unpaid principal balance
      at 11% and is payable monthly in arrears on the first day of each
      month.  Interest on the $200,000 note accrues on the unpaid principal
      balance at 12% and shall be paid monthly in arrears on the first day of
      each month starting November 1, 1993, with the first eighteen months'
      interest having been deferred and paid in equal installments over the
      eighteen-month period commencing November 1, 1993.  Interest expense
      for notes payable to MTDC for the years ended March 31, 1995 and 1994,
      amounted to $40,055 and $48,629.

    On February 17, 1995, the Company signed a Note Restructuring Agreement
      whereby the Company paid $200,000 to MTDC in settlement of the March
      13, 1992 borrowing and signed an Amended and Restated Subordinated
      Secured Promissory Note (the "Amended and Restated Note") in the amount
      of $166,660, with interest at 9% per year, to restructure the balance
      remaining under the April 30, 1991 borrowing.  Under the Amended and
      Restated Note, principal is repayable in 36 monthly installments of
      $4,629 beginning on April 1, 1995, with the final installment payable
      on March 1, 1998.  In connection with the Note Restructuring Agreement,
      MTDC agreed to return to the Company 16,906 warrants to purchase the
      Company's common stock (note 8).

(8) STOCKHOLDERS' EQUITY

    In June 1984, the Company adopted an Incentive Stock Option Plan ("ISOP").
      The ISOP provides that the board of directors may grant options to
      purchase shares of the Company's common stock to employees of the
      Company at not less than the fair market value of the common stock at
      the time of grant.  The Company reserved 26,800 shares for issuance
      under the ISOP.  At March 31, 1995, 18,300 options are available under
      the ISOP.

                                                         (Continued)

                           Notes to Financial Statements


    The Stock Appreciation Rights Plan ("SARP") allowed holders of outstanding
      options under the ISOP to participate by agreeing to cancel their ISOP
      shares.  Some participants received more shares than previously awarded
      under the ISOP; others received fewer.  The SARP provides that the
      board of directors set the terms of each particular award at the time
      of the granting of such award, including, without limitation, the
      identity of the grantee(s), vesting schedules, exercise price,
      expiration date, number of shares subject to the award, and whether and
      to what extent the award shall terminate upon termination of employment
      or competitive activities.  The SARP allows participants to acquire
      common stock of the Company only if the Company is sold.  Due to the
      uncertainty of a sale and the Company's inability to reasonably
      estimate the amount of proceeds if a sale were to occur, the Company
      has not provided for any compensation expense related to the SARP.
      During 1995, the board of directors authorized issuances of up to
      20,000 shares under the SARP.  At March 31, 1995, a total of 15,900
      stock appreciation rights remain outstanding at a price of $1.50 per
      share with vesting dates extending through January 1, 1997. The stock
      appreciation rights expire at various dates through January 29, 2005.

    The Company has granted 4,183 stock options under its 1985 Nonqualified
      Stock Option Plan at per share option prices ranging from $18.75 to
      $35.00.  At March 31, 1995, 1,250 options remain outstanding and are
      exercisable at option prices ranging from $18.75 to $35.00.

    At March 31, 1995, the Company has warrants outstanding which allow the
      holders to purchase 29,145 shares of the Company's common stock at
      prices ranging from $15.00 to $29.99 per share.  These warrants include
      those originally issued to related parties (note 6) and MTDC (note 7).
      The warrants issued to MTDC were returned to the Company for
      cancellation in accordance with the terms of the agreement
      restructuring the Company's debt with MTDC.  These warrants were
      reissued to the remaining holders of the notes.

(9) COMMITMENTS AND CONTINGENCIES

    (A) LEASES
    The Company leases office space under an operating lease agreement,
      expiring on March 31, 1995.  The Company renewed this lease for five
      additional years beginning on April 1, 1995.  In addition to base rent
      due under the terms of the lease, beginning April 1, 1998, the lease
      provides for additional rent calculated as the base rent adjusted for
      the increase in the Consumer Price Index for All Urban Consumers.
      Total rent expense was $95,703 and $93,939 for the years ended March
      31, 1995 and 1994, respectively.

    (B) ROYALTY AGREEMENTS
    In 1989, the Company obtained exclusive worldwide rights to manufacture
      and distribute a unit-dose product for clearing lipemic serum.  In
      consideration of this right, the Company agreed to pay royalties of
      7-1/2% of net sales of the product, with a minimum royalty of $12,000
      per year.  This agreement expires on June 30, 1997.  The Company
      incurred $12,000 of royalty expense for the years ended March 31, 1995
      and 1994, related to this agreement.

    In 1993, the Company obtained the right from a related party to manufacture
      and distribute a slide spinner centrifuge which creates a monolayer of
      whole blood cells.  In consideration of this right, the Company agreed
      to pay royalties of 3-1/2% of net sales of the product and 1-1/2% of
      net sales of related disposable products.  If net sales of such
      disposables reach $500,000 during the royalty period, the disposable
      royalty will increase to 3% of net sales of related disposables.  The
      royalty period is for the five-year period beginning January 30, 1991.
      The Company incurred $1,000 and $6,245 of royalty expense for the years
      ended March 31, 1995 and 1994, respectively, related to this agreement.

    (C) CONTINGENCIES
    On April 22, 1994, the U.S. Food & Drug Administration (FDA) notified the
      Company that the Company was not in compliance with the requirement of
      Good Manufacturing Practice (GMP).  The Company responded on May 10,
      1994 and has taken steps to bring itself into compliance with GMP.  The
      FDA revisited the Company on March 9, 1995 and verbally informed
      management that there were no material deficiencies that would warrant
      a written notice.  No provision has been made in the accompanying
      financial statements for adjustments, if any, should the Company be
      unsuccessful in satisfying the FDA's cirterion for GMP compliance.

(10) INCOME TAXES

    For the years ended March 31, income tax expense consisted of:

</TABLE>

    Actual tax expense for fiscal year 1995 differs from expected tax
      computed applying the U.S. federal corporate income tax rate of
      34% to income before taxes mainly due to the utilization of net operating
      loss carryforwards and research and experimentation credits
      carryforwards.

</TABLE>


     The valuation allowance for deferred tax assets as of April 1, 1994,
       was $197,776.  The net change in the total valuation allowance for the
       year ended March 31, 1995, was a decrease of $26,435.

     At March 31, 1995, the Company had net operating loss carryforwards of
       approximately $161,000 to offset future federal income taxes.  In
       addition, at March 31, 1995, the Company had net operating loss
       carryforwards of approximately $122,000 to offset future state income
       taxes.  The Company's net operating loss carryforwards may be subject
       to limitation in the event that the Company experiences more than a 50%
       change of stock ownership during a three-year period.  At March 31,
       1995, the Company also had research and experimentation credit
       carryforwards of approximately $51,000.  The net operating loss and
       research and experimentation credit carryforwards expire at various
       dates through the year 2007.

(11) 401(K) PLAN

     In October 1993, the Company adopted a deferred compensation plan (the
       "Plan").  Employees with one or more years of service are eligible to
       participate in the Plan.  The Plan requires the Company to match
       employee contributions up to $500 annually.  The Company incurred
       $4,298 and $9,625 for fiscal years 1995 and 1994, respectively, related
       to the employer match under the Plan.

(12) SIGNIFICANT CUSTOMERS

     The Company sells primarily to laboratories, hospitals and doctors'
       offices.  Included in accounts receivable at March 31, 1995 are amounts
       from two customers representing approximately 49% of net accounts
       receivable.  Additionally, 43% and 45% of net sales were to the same
       two customers during the years ended March 31, 1995 and 1994,
       respectively.

                            Notes to Financial Statements

                               March 31, 1994 and 1993


(1) NATURE OF BUSINESS

    Norfolk Scientific, Inc. (d/b/a StatSpin Technologies) was incorporated on
      June 11, 1984, as a successor to Kelley, Newhouse & Company, a
      partnership. The Company purchased assets and rights from its predecessor
      to engage in the development, manufacture, and sale of medical and
      laboratory equipment and supplies.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (A) INVENTORIES
    Inventories are stated at the lower of cost or market, cost being determined
      using the first-in, first-out (FIFO) method.

    (B) PROPERTY AND EQUIPMENT
    Property and equipment is stated at cost.  Depreciation is provided using an
      accelerated method over the estimated useful lives of the respective
      assets.

    (C) OTHER ASSETS, NET
    Other assets consist principally of patents, stated at cost, net of
      accumulated amortization.  The cost of patents is amortized using the
      straight-line method over the estimated useful lives of the respective
      patents.

    (D) INCOME TAXES
    The Financial Accounting Standards Board has issued Statement 109,
      "Accounting for Income Taxes."  Statement 109 requires a change from the
      deferred method required under APB Opinion 11 to the asset and liability
      method.  Under the deferred method, annual income tax expense is matched
      with pretax accounting income by providing deferred taxes at current tax
      rates for timing differences between the determination of net income for
      financial reporting and tax purposes.  The objective of the asset and
      liability method is to establish deferred tax assets and liabilities for
      the temporary differences between the financial reporting basis and the
      tax basis of the Company's assets and liabilities at enacted tax rates
      expected to be in effect when such amounts are to be realized or settled.
      Under Statement 109, the effect on deferred tax assets and liabilities
      of change in tax rates is recognized in income in the period that
      includes the enactment date.

    Effective April 1, 1993, the Company adopted Statement 109.  The cumulative
      effect of the change in the method of accounting for income taxes is not
      material and therefore is not presented separately in the accompanying
      statements of operations and accumulated deficit for the year ended
      March 31, 1994.  Prior years' financial statements have not been restated
      to apply the provisions of Statement 109.

    (E) RECLASSIFICATIONS
    Certain reclassifications have been made to the fiscal 1993 financial
      statements to conform to the fiscal 1994 presentation.

                                                                  (Continued)

      cash is available for operating uses with the approval of Company's board
      of directors and the Massachusetts Technology Development Corporation
      ("MTDC") (see note 7).

                           Notes to Financial Statements


    Under the notes payable agreements, the Company is required to comply with
      various restrictive covenants.  As of March 31, 1994, the Company was not
      in compliance with certain covenants.  The Company has received a waiver
      of such defaults from a majority of the noteholders as of March 31, 1994.

    In addition, 1,079 and 9,999 warrants, respectively, were issued to related
      parties in connection with the April 30, 1991 and March 13, 1992 issuance
      of subordinated notes payable.  These warrants allow the holders to
      purchase 1,079 and 9,999 shares of the Company's common stock at $29.99
      and $15.00 per share through April 30, 1996 and March 13, 1997,
      respectively.  Upon the issuance of the March 13, 1992 warrants, the
      April 30, 1991 warrant price (originally $35.00) was adjusted downward
      to $29.99 pursuant to Section 4(a) of the warrant agreement.  No
      warrants have been exercised.

    During fiscal years 1994 and 1993, the Company performed product development
      and manufacturing activities for a stockholder of the Company.  Revenue
      for these sales and services amounted to $194,748 and $27,320 in fiscal
      years 1994 and 1993, respectively.

      1993, respectively, consist of unsecured subordinated borrowings, with
      interest payable monthly at rates ranging from 11% to 12%.  The notes
      consist of $250,000 in borrowings dated April 30, 1991, payable in 36
      monthly installments of approximately $6,944, commencing May 1, 1993, and

      Interest expense for notes payable to MTDC for the years ended March 31,
      1994 and 1993, amounted to $48,629 and $51,500.

    On February 17, 1995, the Company signed a Note Restructuring Agreement
      whereby the Company paid $200,000 to MTDC in settlement of the March 13,
      1992 borrowing and signed an Amended and Restated Subordinated Secured
      Promissory Note (the "Amended and Restated Note") in the amount of
      $166,660, with interest at 9% per year, to restructure the balance
      remaining under the April 30, 1991 borrowing.  Under the Amended and
      Restated Note, principal is repayable in 36 monthly installments of $4,629
      beginning on April 1, 1995, with the final installment payable on February
      1, 1998.  In connection with the Note Restructuring Agreement, MTDC agreed
      to return to the Company 16,906 warrants to purchase the Company's common
      stock (note 8).

    The balance sheet at March 31, 1994 has been adjusted to reflect
      indebtedness to MTDC under the terms of the Note Restructuring Agreement.

                                                                    (Continued)

(8) STOCKHOLDERS' EQUITY

    In June 1984, the Company adopted an Incentive Stock Option Plan ("ISOP").
      The ISOP provides that the board of directors may grant options to
      purchase shares of the Company's common stock to employees of the Company
      at not less than the fair market value of the common stock at the time of
      grant. The Company reserved 26,800 shares for issuance under the ISOP.
      At March 31, 1994, 18,300 options are available under the ISOP.

    The Stock Appreciation Rights Plan ("SARP") allowed holders of outstanding
      options under the ISOP to participate by agreeing to cancel their ISOP
      shares.  Some participants received more shares than previously awarded
      under the ISOP; others received fewer.  The SARP provides that the board
      of directors set the terms of each particular award at the time of the
      granting of such award, including, without limitation, the identity of the
      grantee(s), vesting schedules, exercise price, expiration date, number of
      shares subject to the award, and whether and to what extent the award
      shall terminate upon termination of employment or competitive activities.
      The SARP allows participants to acquire common stock of the Company only
      if the Company is sold.  Due to the uncertainty of a sale and the
      Company's inability to reasonably estimate the amount of proceeds if a
      sale were to occur, the Company has not provided for any compensation
      expense related to the SARP.  During 1994, the board of directors
      authorized issuances of up to 20,000 shares under the SARP.  At March 31,
      1994, a total of 17,900 stock appreciation rights remain outstanding
      at a price of $1.50 per share with vesting dates extending through
      January 1, 1997.  The stock appreciation rights expire at various
      dates through January 29, 2005.

    The Company has granted 4,183 stock options under its 1985 Nonqualified
      Stock Option Plan at per share option prices ranging from $18.75 to
      $35.00.  At March 31, 1994, 1,250 options remain outstanding and
      are exercisable at option prices ranging from $18.75 to $35.00.

    At March 31, 1994, the Company has warrants outstanding which allow the
      holders to purchase 29,145 shares of the Company's common stock at prices
      ranging from $15.00 to $29.99 per share.  These warrants include those
      issued to related parties (note 6) and MTDC (note 7) during 1992, as well
      as 1,000 warrants previously issued and subsequently increased to 1,161
      warrants pursuant to Section 6.4 of the warrant agreement dated January
      23, 1989.

(9) COMMITMENTS AND CONTINGENCIES

    (A) LEASES
    The Company leases office space under an operating lease agreement,
      expiring on March 31, 1995.  The Company, at its option, may extend the
      term of the lease for an additional five-year period.  In addition to
      base rent due under the terms of the lease, beginning April 1, 1993, the
      lease provides for additional rent calculated as the base rent adjusted
      for the increase in the Consumer Price Index for All Urban Consumers.
      Such additional rent is adjusted biannually.  Total rent expense was
      $93,939 and $87,662 for the years ended March 31, 1994 and 1993,
      respectively.

    Future minimum lease payments are as follows:

    (B) ROYALTY AGREEMENTS
    In 1989, the Company obtained exclusive worldwide rights to manufacture and
      distribute a unit-dose product for clearing lipemic serum.  In
      consideration of this right, the Company agreed to pay royalties of 7-
      1/2% of net sales of the product, with a minimum royalty of $12,000 per
      year.  This agreement expires on June 30, 1994.  The Company incurred
      $12,000 of royalty expense for the years ended March 31, 1994 and 1993,
      related to this agreement.

    During the year ended March 31, 1993, the Company obtained the right from a
      related party to manufacture and distribute a slide spinner centrifuge
      which creates a monolayer of whole blood cells.  In consideration of this
      right, the Company agreed to pay royalties of 3-1/2% of net sales of the
      product and 1-1/2% of net sales of related disposable products.  If net
      sales of such disposables reach $500,000 during the royalty period, the
      disposable royalty will increase to 3% of net sales of related
      disposables.  The royalty period is for the five-year period beginning
      January 30, 1991.  The Company incurred $6,245 and $12,317 of royalty
      expense for the years ended March 31, 1994 and 1993, respectively,
      related to this agreement.

    (C) CONTINGENCIES
    On April 22, 1994, the U.S. Food & Drug Administration (FDA) notified the
      Company that the Company was not in compliance with the requirement of
      Good Manufacturing Practice (GMP).  The Company responded on May 10, 1994
      and has taken steps to bring itself into compliance with GMP.  The FDA
      has agreed to put the Company on the list for re-inspection.  Management
      believes that the Company will be found in GMP compliance in the
      forthcoming re-inspection.  No provision has been made in the
      accompanying financial statements for adjustments, if any, should the
      Company be unsuccessful in satisfying the FDA s criterion for GMP
      compliance.

</TABLE>

    Actual tax expense for fiscal year 1994 differs from expected tax computed
      applying the U.S. federal corporate income tax rate of 34% to income
      before taxes mainly due to the utilization of net operating loss
      carryforwards and research and experimentation credits carryforwards.

                                                                 (Continued)

     The valuation allowance for deferred tax assets as of April 1, 1993, was
       $215,210.  The net change in the total valuation allowance for the year
       ended March 31, 1994, was a decrease of $17,434.

     At March 31, 1994, the Company had net operating loss carryforwards of
       approximately $302,000 to offset future federal income taxes.  In
       addition, at March 31, 1994, the Company had net operating loss
       carryforwards of approximately $168,000 to offset future state income
       taxes.  The Company's net operating loss carryforwards may be subject to
       limitation in the event that the Company experiences more than a 50%
       change of stock ownership during a three-year period.  At March 31, 1994,
       the Company also had research and experimentation credit carryforwards of
       approximately $51,000.  The net operating loss and research and
       experimentation credit carryforwards expire at various dates through the
       year 2007.

(11) 401(K) PLAN

     In October 1993, the Company adopted a deferred compensation plan (the
       "Plan").  Employees with one or more years of service are eligible to
       participate in the Plan.  The Plan requires the Company to match employee
       contributions up to $500 annually.  During fiscal year 1994, the Company
       incurred $9,625 related to the employer match under the Plan.

(12) SIGNIFICANT CUSTOMERS

     The Company sells primarily to laboratories, hospitals and doctors'
       offices.  Included in accounts receivable at March 31, 1994 are amounts
       from two customers representing approximately 39% of net accounts
       receivable.  Additionally, 45% and 38% of net sales were to the same
       customer during the years ended March 31, 1994 and 1993, respectively.

                     UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS


The  combination of International Remote Imaging Systems ("IRIS") and Norfolk
Scientific, Inc., doing business as StatSpin Technologies ("StatSpin") is
expected to be accounted for using the pooling-of-interests method of accounting
which accounts for a business combination as the uniting of the ownership
interests by exchange of equity securities.  Under this method of accounting,
ownership interests continue and the former bases of accounting are retained;
the recorded assets and liabilities of IRIS and StatSpin are carried forward to
the combined corporation at their recorded amounts; income of the combined
corporation includes income of IRIS and StatSpin for the entire fiscal period in
which the combination occurs; and the reported income of the separate
corporations for prior periods is combined and restated as income of the
combined corporation.

The accompanying Unaudited Pro Forma Condensed Combined Balance Sheet combines
the balance sheets of IRIS and StatSpin as of September 30, 1995.  The annual
Unaudited Pro Forma Condensed Combined Statements of Income combine the
statements of income of IRIS for the fiscal years ended December 31, 1992, 1993
and 1994 with those of StatSpin for the fiscal years ended March 31, 1993, 1994
and 1995. The statements of income  for StatSpin included in the Unaudited Pro
Forma Condensed Combined Statements of Income for the nine months ended
September 30, 1995 and 1994 have been recast to conform with IRIS's fiscal year
end.

The Unaudited Pro Forma Condensed Combined Financial Statements are based upon
the respective historical financial statements of IRIS and StatSpin and should
be read in conjunction with those historical financial statements and the
related notes thereto, and with the Notes to Unaudited Pro Forma Condensed
Combined Financial Statements.  The Pro Forma Condensed Combined Financial
Statements do not purport to be indicative of the results which would actually
have been obtained if the merger had been effected on the date or dates
indicated or which may be obtained in the future.

                 NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS


1. Periods Presented

The annual Unaudited Pro Forma Condensed Combined Financial Statements have been
prepared by combining the separate historical financial statements of IRIS and
StatSpin for their historical fiscal periods.  The historical financial
information of StatSpin included in the Unaudited Pro Forma Condensed Combined
Statements of Income for the nine months ended September 30, 1995 and 1994 have
been recast to conform with IRIS's fiscal year end.

The Unaudited Pro Forma Condensed Combined Balance Sheet as of September 30,
1995 reflects the issuance of approximately 340,179 shares of IRIS common stock
in exchange for all shares of StatSpin common stock (including common stock
attributable to stock appreciation rights) outstanding at September 30, 1995,
based upon an exchange ratio of 4.0950 shares of IRIS common stock (assuming an
IRIS stock price of $7.58 per share) for each share of StatSpin common stock.

2. Earnings Per Share

The unaudited pro forma net income (loss) per common and common equivalent share
outstanding was computed based on the combined weighted average number of shares
of common stock and common stock equivalents of IRIS and StatSpin outstanding
based upon an exchange ratio of 4.0950 shares of IRIS common stock for each
share of StatSpin common stock (including common stock attributable to stock
appreciation rights); a warrant to purchase 4.0950 shares of IRIS common stock
for each outstanding StatSpin warrant; and an option to purchase 4.0950 shares
of IRIS common stock for each outstanding StatSpin warrant.

3. Pro Forma Adjustments

The only pro forma adjustment is to restate common stock and paid in capital for
the difference in the par value of StatSpin common stock surrendered and the par
value of IRIS common stock issued.

The Unaudited Pro Forma Condensed Combined Financial Statements contain one
adjustment to conform the accounting policies of the two companies.  IRIS
retroactively adopted the accounting standards required by Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109") effective January 1, 1991.  StatSpin adopted the standards required by FAS
109 effective April 1, 1993.  The Unaudited Pro Forma Condensed Combined
Statement of Income for 1992 contains an adjustment to reflect both IRIS and
StatSpin adopting the standards required by FAS 109 effective January 1, 1991.
The effect of this adjustment on the combined historical financial data as
presented herein was a reclassification of the utilization of a net operating
loss carryforward from an extraordinary item


<PAGE>

to an offset against the income tax provision because utilization of net
operating loss carryforwards is not treated as an extraordinary item under
SFAS 109.

No provision has been reflected in the Unaudited Pro Forma Condensed  Combined
Financial Statements for direct expenses related to the merger.  IRIS and
