1.      General

        In the opinion of management, the June 30 unaudited condensed
        consolidated financial statements contain all adjustments (consisting
        only of normal recurring accruals) which the Company considers
        necessary for a fair presentation of the financial position and
        results of operations of the Company. Operating results for the
        periods ended June 30, 1999 are not necessarily indicative of the
        results to be expected for the entire year. Certain information and
        footnote disclosures normally included in financial statements
        prepared in accordance with generally accepted accounting principles
        have been condensed or omitted. The preparation of financial
        statements in conformity with generally accepted accounting principles
        requires management to make estimates and assumptions that affect the
        reported amounts of assets and liabilities, including disclosures of
        contingent assets and liabilities and the reported amounts of revenues
        and expenses during the reporting periods. Actual results could differ
        from those estimates. These unaudited condensed consolidated financial
        statements should be read in conjunction with the Company's
        consolidated financial statements for the year ended December 31, 1998
        included in the Company's Annual Report on Form 10-K.


2.      Strategic Alliance

        On June 15, 1999, the Company and Johnson & Johnson Medical, Division
        of Ethicon, Inc. ("JJM") signed an agreement (the "JJM Agreement")
        providing JJM with exclusive marketing and distribution rights to
        INTEGRA(TM) Artifical Skin ("INTEGRA Skin") worldwide, excluding
        Japan, for a minimum of ten years. JJM may extend the JJM Agreement
        for successive ten-year periods solely at its discretion. Under the
        JJM Agreement, the Company will continue to manufacture INTEGRA Skin
        and will collaborate with JJM to conduct research and development and
        clinical research aimed at expanding indications and developing future
        products in the field of skin repair and regeneration.

        Upon signing the JJM Agreement, the Company received a payment from JJM
        of $5.3 million for the exclusive use of the Company's trademarks and
        regulatory filings related to INTEGRA Skin and certain other rights.
        This amount has been recorded as deferred revenue and will be amortized
        over the ten-year term of the JJM Agreement. Additionally, the JJM
        Agreement requires JJM to make non-refundable payments to the Company
        each year based upon minimum purchases of INTEGRA Skin. As a result, the
        Company received a $1.2 million prepayment upon signing the JJM
        Agreement for minimum purchases in 1999, which was recorded in current
        liabilities as customer advances.

        The JJM Agreement also provides for annual research funding beginning
        in 2000 and additional payments upon achieving certain clinical
        and regulatory milestones and for funding expansion of the Company's
        INTEGRA Skin production capacity as certain sales targets are achieved.

3.      Acquisition

        On March 29, 1999 the Company acquired the business, including certain
        assets and liabilities, of the NeuroCare group of companies
        ("NeuroCare"), a leading provider of neurosurgical products. The $25.4
        million acquisition price was comprised of $14.0 million of cash,
        $11.0 million of assumed indebtedness under a term loan from Fleet
        Capital Corporation ("Fleet"), and $0.4 million of contingent purchase
        price adjustments. Fleet is also providing a $4.0 million revolving
        credit facility to fund working capital requirements, of which $13,000
        was drawn down as of June 30, 1999. The cash portion of the purchase
        price was financed in part by affiliates of Soros Private Equity
        Partners LLC, through the sale of $10 million of Series B Convertible
        Preferred Stock and warrants. The convertible preferred shares are
        convertible into 2,617,801 shares of the Company's common stock, have
        a liquidation preference of $10.0 million with a 10% compounded annual
        return and are senior to all other equity securities of the Company.
        The warrants issued are for the right to acquire 240,000 shares of the
        Company's common stock at an exercise price of $3.82 per share. The
        acquisition has been accounted for under the purchase method of
        accounting. The purchase price has been preliminarily allocated based
        on estimated fair values at the date of acquisition. This preliminary
        allocation has resulted in acquired intangibles and goodwill of
        approximately $13.5 million, which is being amortized on a
        straight-line basis over 15 years. The following is a summary of the
        preliminary allocation (in thousands):

            Cash.................................................  $    285
            Accounts receivable..................................     4,958

        The following unaudited pro forma financial information assumes that the
        acquisition had occurred as of the beginning of each period (in
        thousands):

                                                 For the Six Months
                                                   Ended June 30,

                  per share...............    $  (0.43)       $  (0.41)

        The pro forma amounts for the six months ended June 30, 1999 exclude the
        $3.7 million aftertax gain ($0.22 per share) from the sale of the
        Panafil(R) product line (see Note 4). The pro forma amounts are based
        upon certain assumptions and estimates, and do not reflect any
        activities that might have occurred as a result of the acquisition. The
        pro forma results do not necessarily represent results that would have
        occurred if the acquisition

        had taken place on the basis assumed above, nor are they indicative of
        the results of future combined operations.


4.      Panafil(R) Product Line Disposition

        In January 1999, the Company sold the Rystan Panafil(R) product line,
        including the brand name and related production equipment, to
        Healthpoint, Ltd. for $6.4 million in cash. The Company recognized a
        pre-tax gain of $4.2 million after adjusting for the net cost of the
        assets sold and for expenses associated with the divestiture, including
        the closing of the Rystan facility.

5.      Loss per share and comprehensive loss

        Basic and diluted net loss per share and comprehensive loss for the
        three and six months ended June 30 were as follows (in thousands):

8.      Segment Reporting

        The Company's reportable business segments are outlined in the Company's
        1998 audited financial statements. As a result of the NeuroCare
        acquisition, the Company operates its neurosurgical business activities
        as a separate business segment. The majority of the Company's
        neurosurgical activity was previously included in the medical products
        business segment. Additionally, subsequent to the transfer of all
        INTEGRA Skin sales and marketing activities to JJM under the JJM
        Agreement signed in June 1999 (see Note 2) and the sale of the
        Panafil(R) product line in the first quarter of 1999, the results of the
        former skin repair and burns segment are now included in the medical
        products segment (which will now be referred to as the surgical products
        segment), as these products are now sold under OEM arrangements.

9.      Legal Matters

        In July 1996, the Company filed a patent infringement lawsuit against
        three parties: Merck KGaA, a German corporation, Scripps Research
        Institute, a California nonprofit corporation, and David A. Cheresh,
        Ph.D., a research scientist with Scripps. The complaint charges, among
        other things, that the defendant Merck KGaA willfully and deliberately
        induced, and continues to willfully and deliberately induce, defendants
        Scripps Research Institute and Dr. David A. Cheresh to infringe on one
        of the Company's patents. This patent is one of a group of five patents
        granted to The Burnham Institute and licensed by the Company that are
        based on the interaction between a family of cell surface proteins
        called integrins and the arginine-glycine-aspartic acid (known as "RGD")
        peptide sequence found in many extracellular matrix proteins. The
        defendants have filed a countersuit asking for an award of defendants'
        reasonable attorney fees.

        The ultimate liability of any litigation matter cannot be determined
        because of the considerable uncertainties that exist. The Company's
        financial statements do not reflect any significant amounts related to
        possible unfavorable outcomes of the matter above. However, it is
        possible that the Company's results of operations, financial position
        and cash flows in a particular period could be materially affected by an
        unfavorable outcome of the above matter.

Item 2.   Management's Discussion and Analysis of Financial Condition
          and Results of Operations

The following discussion should be read in conjunction with the Company's
consolidated financial statements, the notes thereto and the other financial
information included elsewhere in this report and in the Company's 1998 Annual
Report on Form 10-K filed with the Securities and Exchange Commission.

General

The Company has developed principally by combining existing businesses,
acquiring synergistic technologies and forming strategic business and
technological alliances. As a result of the Company's acquisition of Rystan
Company, Inc. ("Rystan") in September 1998 and the acquisition of the
NeuroCare Group of companies ("NeuroCare") in March 1999, the Company's
consolidated financial results for the three and six months ended June 30,
1999 and 1998 may not be directly comparable. In addition, the Company's
financial information discussed below should be considered in light of the
Company's sale of the Panafil(R) product line on January 5, 1999.

Results of Operations

Three Months Ended June 30, 1999 Compared to Three Months Ended June 30, 1998

Total revenues increased significantly to $12.6 million for the three months
ended June 30, 1999 from $3.8 million for the three months ended June 30, 1998
due to the acquisitions of NeuroCare and Rystan. Excluding the effects of the
NeuroCare and Rystan acquisitions, total revenues decreased to $3.6 million for
the three months ended June 30, 1999, primarily from a decrease in product
sales. Product sales, excluding the NeuroCare and Rystan acquisitions, decreased
from $3.4 million for the three months ended June 30, 1998 to $3.2 million for
the three months ended June 30, 1999. This decrease resulted from a decrease of
$0.4 million in sales of INTEGRA(TM) Artificial Skin ("INTEGRA Skin"), which was
partially offset by an increase of $0.2 million in sales of other surgical
products. On June 15, 1999, the Company and Johnson & Johnson Medical, Division
of Ethicon, Inc. ("JJM") signed an agreement (the "JJM Agreement") providing JJM
with exclusive marketing and distribution rights to INTEGRA Skin worldwide,
excluding Japan, for a minimum of ten years. Under the JJM Agreement, the
Company will continue to manufacture INTEGRA Skin and will collaborate with JJM
to conduct research and development and clinical research aimed at expanding
indications and developing future products in the field of skin repair and
regeneration. The Company believes that growth in the use and sale of INTEGRA
Skin will depend on JJM's ability to market the product for reconstructive and
other additional indications.

Excluding the NeuroCare and Rystan acquisitions, sales of the Company's other
surgical products increased to $2.1 million for the three months ended June 30,
1999 from $1.9 million for the three months ended June 30, 1998. This increase
was related a $0.4 million increase in sales of infection control products,
offset by a $0.2 million decrease in sales of other OEM products. Because
significant portions of the Company's surgical products segment sales are made
to marketing partners and distributors, quarter-to-quarter sales in the
segment can vary significantly depending on the timing of shipments to these
partners and distributors.

                                      11



Product sales from NeuroCare and Rystan were $8.9 million in the current
quarter, with the Panafil(R) product line providing $0.5 million of sales.
Although under the terms of the Panafil(R) disposition agreement the Company is
entitled to revenue based on identified sales into the podiatry and burn care
markets (less certain fees), the Company currently anticipates a decline in
Panafil(R) revenue in future periods.

Export sales for the three months ended June 30, 1999 were $3.2 million,
compared to $0.7 million for the three months ended June 30, 1998, primarily
due to the acquisition of NeuroCare.

Other revenue, which includes grant revenue, license fees, product development
revenue and royalties, was approximately $0.4 million for the three months
ended June 30, 1999 compared to $0.5 million for the three months ended June
30, 1998. The Company continues to seek research grants, licensing
arrangements and development funding for several of its technologies, although
the timing and amount of such revenue, if any, can not be predicted.

Cost of product sales increased significantly to $7.7 million (63% of product
sales) for the three months ended June 30, 1999 from $1.6 million (48% of
product sales) for the three months ended June 30, 1998 because of the effects
of the NeuroCare and Rystan acquisitions. The significant increase in cost of
product sales as a percentage of product sales is primarily attributable to $1.8
million of fair value purchase accounting adjustments related to NeuroCare and
Rystan inventory sold in the second quarter of 1999 and $0.5 million of
inventory reserves related to certain slow-moving products within the
neurosurgical business where the Company is reducing its sales and marketing
efforts. Excluding purchase accounting adjustments, cost of product sales would
have been 49% of product sales in the second quarter of 1999.  Excluding the
NeuroCare and Rystan acquisitions, cost of product sales increased to $1.8
million (53% of product sales) for the three months ended June 30, 1999. The
Company anticipates that the inclusion of INTEGRA Skin sales in the surgical
products segment and the lower gross margin percentage associated with sales
of INTEGRA Skin under the JJM Agreement will adversely affect the gross margin
percentage within the surgical products business. The impact on gross margin
percentage will depend on capacity utilization and product mix  within the
surgical products business. The Company's consolidated gross margin should
improve in the fourth quarter of 1999 after all inventory affected by the fair
value purchase accounting adjustments has been sold.

Research and development expense increased to $2.3 million for the three-month
period ended June 30, 1999 from $2.1 million for the three-month period ended
June 30, 1998 because of the effect of the NeuroCare acquisition. Excluding the
NeuroCare acquisition, research and development expense decreased to $1.6
million for the three months ended June 30, 1999. This decrease resulted from
the elimination of several collaborative research programs in non-core
development programs. The Company anticipates adjusting the allocation of
research and development resources as it combines NeuroCare's development
activities. The JJM Agreement will provide the Company with research funding for
INTEGRA Skin beginning in 2000. Additional funding to support the Company's
research and development programs will be available if certain clinical and
regulatory milestones related to INTEGRA Skin are achieved. The amount and
allocation of resources to fund research and development will vary depending
upon a number of factors, including the progress of development of the Company's
technologies, the timing and outcome of pre-clinical and clinical results,
changing competitive conditions, continued program funding levels, potential
funding opportunities and determinations with respect to the commercial
potential of the Company's technologies.

                                      12



Selling and marketing expense increased to $2.9 million for the three-month
period ended June 30, 1999 from $1.5 million for the three-month period ended
June 30, 1998 because of the effect of the NeuroCare acquisition. Excluding
the NeuroCare acquisition, selling and marketing expense decreased to $1.3
million for the three months ended June 30, 1999. This decrease resulted from
the reduction of INTEGRA Skin selling and marketing activities, which was
partially offset by increased expenses relating to the Company's DuraGen(TM)
dural graft matrix ("DuraGen") product pre-launch activities. In July 1999,
the Company received FDA 510(K) clearance in the United States for DuraGen as
a dura substitute for the repair of the dura mater of the brain. In February
1999, the Company received CE Mark Certification for DuraGen which allows the
Company to market this new neurosurgical implant throughout the 18 member
countries of the European Union. In the future, selling and marketing expenses
related to INTEGRA Skin are expected to decrease, as these activities will be
assumed by JJM.

General and administrative expense increased to approximately $4.5 million for
the three-month period ended June 30, 1999 from $2.7 million for the
three-month period ended June 30, 1998 primarily due to the effect of the
NeuroCare and Rystan acquisitions. Included in the amount for the three months
ended June 30, 1999 is $0.8 million of employee severance costs relating to
NeuroCare's recently closed Wisconsin facility. Excluding these charges and
the remainder of the effect of the NeuroCare and Rystan acquisitions, general
and administrative costs decreased to $2.3 million for the three months ended
June 30, 1999. This decrease is primarily the result of decreased legal fees,
as the Company resolved various litigation matters in 1998.

While the Company believes that the consolidation of its corporate and
distribution facilities will result in an overall cost reduction, the Company
is anticipating a short-term increase in operating costs related to the
NeuroCare acquisition, including additional severance costs, the transfer and
installation of distribution and telecommunication equipment and other
transition and training costs required as a result of the Wisconsin facility
closing.

Other income, net, decreased from $0.8 million for the three months ended June
30, 1998 to $9,000 for the three months ended June 30, 1999. This decrease is
primarily the result of a $0.5 million litigation settlement gain recorded in
the second quarter of 1998 and interest expense of $0.2 million in the current
quarter on the Fleet term loan assumed in the NeuroCare acquisition.

The income tax benefit of $1.2 million for the three months ended June 30,
1999 is due to the deferred tax benefits recognized on the consolidated
post-acquisition losses to the extent of the deferred tax liability recorded
in the NeuroCare acquisition. Additional income tax benefit is expected
through the remainder of 1999 as anticipated additional consolidated losses
are incurred and the deferred tax liability is further reduced.

Six Months Ended June 30, 1999 Compared to Six Months Ended June 30, 1998

Total revenues increased significantly to $17.5 million for the six months
ended June 30, 1999 from $8.4 million for the six months ended June 30, 1998
as a result of the NeuroCare and Rystan acquisitions. Excluding the effects of
the NeuroCare and Rystan acquisitions, total revenues decreased to $7.5
million for the six months ended June 30, 1999, primarily from a decrease of
$1.1 million in other revenue. Excluding the effects of the NeuroCare and
Rystan acquisitions, product sales increased to $6.7 million for the six
months ended June 30, 1999 from $6.5 million for the six months ended June 30,
1998. This increase was the result of a $0.8 million increase in sales of other
surgical products, which was offset by a $0.6 million decrease in sales of
INTEGRA Skin. Excluding the

                                      13



NeuroCare and Rystan acquisitions, sales of the Company's other surgical
products increased to $4.4 million for the six months ended June 30, 1999 from
$3.6 million for the six months ended June 30, 1998. This increase was primarily
related to increased sales of the Company's dental and other OEM products.
Product sales from NeuroCare (post-acquisition) and Rystan were $10.0 million in
the six months ended June 30, 1999, with the Panafil(R) product line providing
$0.9 million of sales. Export sales for the six months ended June 30, 1999
increased to $4.2 million from $1.3 for the six months ended June 30, 1998.

Other revenue was $0.9 million for the six months ended June 30, 1999 compared
to $1.9 million for the six months ended June 30, 1998. The decrease related
primarily to a non-refundable $1.0 million licensing fee from Century Medical,
Inc. in the first quarter of 1998. The Company continues to seek research
grants, licensing arrangements and development funding for several of its
technologies, although the timing and amount of such revenue, if any, can not
be predicted.

Cost of product sales increased significantly to $10.4 million (62% of product
sales) for the six months ended June 30, 1999 from $3.3 million (51% of product
sales) for the six months ended June 30, 1998 because of the effects of the
NeuroCare and Rystan acquisitions. The significant increase in cost of product
sales as a percentage of product sales is primarily attributable to $2.0 million
of fair value purchase accounting adjustments related to NeuroCare and Rystan
inventory and $0.5 million of inventory reserves related to certain slow-moving
products within the neurosurgical business. Excluding purchase accounting
adjustments, cost of product sales would have been 50% of product sales for the
six months ended June 30, 1999. Excluding the NeuroCare and Rystan acquisitions,
cost of product sales increased to $3.8 million (57% of product sales) for the
six months ended June 30, 1999, compared to $3.3 million (51% of product sales)
for the six months ended June 30, 1998, largely due to lower utilization of the
INTEGRA Skin manufacturing capacity in the first quarter of 1999.

Research and development expense increased to $4.3 million for the six months
ended June 30, 1999 compared to $4.2 million for the six months ended June 30,
1998 due to the NeuroCare acquisition. Excluding the NeuroCare acquisition,
research and development expense decreased to $3.6 million for the six months
ended June 30, 1999. This decrease resulted from the elimination of several
collaborative research programs in non-core development programs.

Selling and marketing expense increased to $4.5 million for the six-month
period ended June 30, 1999 from $3.1 million for the six-month period ended
June 30, 1998 because of the effect of the NeuroCare acquisition. Excluding
the NeuroCare acquisition, selling and marketing expense decreased to $2.8
million for the three months ended June 30, 1999. This decrease resulted from
the reduction of INTEGRA Skin selling and marketing costs, which was partially
offset by increased expenses relating to the Company's pre-launch activities
for DuraGen.

General and administrative expense increased to $6.7 million for the six-month
period ended June 30, 1999 from $5.6 million for the six-month period ended
June 30, 1998 due primarily to the effects of the NeuroCare and Rystan
acquisitions. Included in the amount for the six months ended June 30, 1999 was
$0.8 million of employee severance costs relating to NeuroCare's recently
closed Wisconsin facility. Excluding these charges and the remainder of the
effect of the NeuroCare and Rystan acquisitions, general and administrative
costs decreased to $4.3 million for the three months ended June 30, 1999. This
decrease is primarily the result of a significant decrease in legal fees in
1999, as the Company resolved various litigation matters in 1998, and a $0.2
million asset impairment charge recorded in the first quarter of 1998.

                                      14



Other income, net increased to $4.4 million for the six months ended June 30,
1999 from $1.3 million for the six months ended June 30, 1998. This increase
is primarily the result of a $4.2 million gain ($3.7 million net of taxes)
related to the sale in January 1999 of the Panafil(R) product line along with
certain other assets related to the product. Offsetting this gain is a $0.5
million litigation settlement gain recorded in the second quarter of 1998 and
interest expense of $0.3 million in the six months ended June 30, 1999 on the
Fleet term loan assumed in the NeuroCare acquisition.

The income tax benefit of $0.8 million for the six months ended June 30, 1999
included $0.5 million of taxes associated with the gain on the sale of the
Panafil(R) product line, offset by a $1.2 million deferred tax benefit discussed
above.

Liquidity and Capital Resources

The Company has funded its operations to date primarily through private and
public offerings of equity securities, product revenues, research and
collaboration funding, borrowings under a revolving credit line and cash
acquired in connection with business acquisitions. At June 30, 1999, the Company
had cash, cash equivalents and short-term investments of approximately $23.2
million and $10.6 million in short and long-term debt. The Company's principal
uses  of funds during the six-month period ended June 30, 1999 were $14.1
million in the acquisition of NeuroCare, $0.8 million in purchases of property
and equipment and $0.4 million in repayments of term loans. Cash flows provided
by operations for the six months ended June 30, 1999 were $1.6 million, which
included $6.5 million received from the JJM Agreement. During the six months
ended June 30, 1999, the Company also raised $10.0 million with the sale of
Series B Preferred Stock and warrants to Soros Private Equity Partners LLC,
assumed $11 million of term debt in connection with the NeuroCare acquisition
and received $6.4 million in connection with the sale of the Panafil(R) product
line.

The Company anticipates that it will continue to use its liquid assets to fund
operations until sufficient revenues can be generated through product sales and
collaborative arrangements. With the acquisition of NeuroCare, the Company has
approximately $2.4 million in liabilities related to the acquisition that will
need to be funded over the remainder of 1999, including $0.4 million of a
contingent purchase price adjustment. As part of the assumption of the NeuroCare
term loan, the Company obtained a $4.0 million revolving credit facility to
fund working capital needs of NeuroCare, of which $13,000 was drawn down at June
30, 1999. The Company anticipates that NeuroCare will utilize the revolving
credit facility to fund its capital needs. In the short-term, the Company
believes that it has sufficient resources to fund its operations. However, in
the longer-term, there can be no assurance that the Company will be able to
generate sufficient revenues to obtain positive operating cash flows or
profitability.

Year 2000 Disclosure

As is true for most companies, the potential for problems involving existing
information systems as we approach and pass January 1, 2000 creates a risk for
the Company. These potential problems are the result of the inability of
certain date-sensitive computer programs and embedded controls to recognize a
two-digit date field designated as "00" as the year 2000 instead of the year
1900, the consequences of which could lead to system failures or
miscalculations causing disruptions to operations and normal business
activities. This is a significant issue with far reaching implications, some
of which cannot be anticipated or predicted with any degree of certainty and
is commonly referred to as a Year 2000 (Y2K) compliance issue.

                                      15



The Company's Businesses
The Company has completed its initial assessment as well as its correction
plan for all areas previously identified as potentially compromised by the
advent of Y2K. This correction plan was comprised of (i) the assessment of
information technology systems ("IT systems") and non-IT systems for Y2K
compliance, (ii) the modification and/or replacement of non-compliant systems,
(iii) the testing of modified and/or replaced systems, and (iv) the deployment
of Y2K compliant systems. Actions taken to achieve Y2K compliance included
upgrading current hardware and software as well as purchasing additional
hardware and software to enhance current IT systems. The majority of the
capital expenditures and operating costs associated with these upgrades and
purchases would have occurred in the normal course of business regardless of
the Y2K issue, although a portion of such expenditures and costs is
attributable to the Company's Y2K correction plan. The Company's upgrades and
purchases for all critical systems have been implemented and tested. We have
tested and confirmed that all critical systems are fully Y2K compliant or only
require a simple manual update on the first of the new year to be compliant.
The few remaining non-critical systems will be made Y2K compliant before
December 31, 1999 as part of regularly scheduled system upgrades.

The only business division of the Company that makes and sells products that
contain computer processors is Integra NeuroCare. The Company has determined
that the Camino line of intracranial pressure monitors does not include a
dating function, and therefore will not be affected by Y2K considerations. The
Neuro Navigational line of neuroendoscopy products does contain certain dating
functions that will be affected by Y2K considerations, but the substantive
performance of the devices will not be affected. The Company is providing its
customers with instructions for resetting the dating function to overcome
effects of the Y2K considerations. No other products manufactured by the
Company contain any materials that would make such products susceptible to
disruptions relating to the Y2K.

Suppliers
The Company has been reviewing and has requested assurances on the status of
the Y2K readiness of its critical suppliers. Many of these suppliers, however,
have provided limited assurances on the status on their Y2K readiness. The
Company plans to continue to monitor critical suppliers during 1999. As a
precaution, Integra LifeSciences is beginning to build inventories of both raw
materials and finished goods so that temporary shortages or an increase in
product demand will not negatively effect the companies operations. The
Company has also reviewed information regarding its major customers to assess
their readiness for Y2K. If a significant number of suppliers and customers
experience disruptions as a result of the Y2K issue, this could have a
material adverse effect on the financial position and results of operations of
the Company. Although the Company is formulating contingency plans to deal
with Y2K problems of key business partners and major customers, there can be
no assurance that these plans will address all Y2K problems or that the
implementation of these plans will be successful.

Given the information available at this time, the Company currently
anticipates that the amount that will be spent to complete its Y2K correction
plan will not have a material adverse impact on the Company's business,
results of operations, financial position and cash flow. Furthermore, Integra
does not expect that the effects of any Y2K non-compliance on its systems
will have any material adverse impact on the Company's business, results of
operations, financial positions or cash flows. However, there can be no
assurance that Integra will not incur additional expenses or experience
business disruption as a result of systems problems associated with the
century change, including system and equipment problems with third parties
with which Integra does business.
