         DISCLOSURES RELATED TO DISTRIBUTOR SALES TRANSACTIONS, AS NECESSARY, IN
         FUTURE FILINGS.

RESPONSE TO COMMENT 1

As with all customers, the Company records revenues on sales to distributors net
of provisions for estimated returns at the time of sale. As further demonstrated
below, the Company believes that its revenue recognition policies and existing
disclosures are in full compliance with SAB 104 and SFAS 48.

DISTRIBUTOR RELATIONSHIPS

The majority of the Company's sales are through its direct (i.e. employed) sales
organization. The Company sells its products to independent stocking
distributors (i.e. distributors that purchase and physically take possession of
product) in those countries where the Company does not have a direct sales
force. In 2005, 2004 and 2003, sales in the United States represented
approximately 75%, 80% and 75% of product revenues, respectively, and virtually
all of the Company's sales to stocking distributors in 2005, 2004 and 2003 were
outside of the United States. The Company maintained a variety of relationships
with over 600 active distributors both domestically and internationally in 2005.
These distributors fell into three categories: (1) "customer-repping"
distributors which process orders for end-users but which hold no inventory; (2)
foreign stocking distributors which maintain inventory for their resale; and (3)
other fully integrated medical device companies for whom the Company
manufactures specific products or components of products. Each of these
distributor relationships is discussed below.

1.  "CUSTOMER-REPPING" DISTRIBUTORS

Through November 2005, the Company's JARIT business sold products through
"customer-repping" distributors. Sales to "customer-repping" distributors are
economically analogous to sales through the Company's direct sales organization.
That is, "customer-repping" distributors did not stock inventory and did not
take possession of product. Rather, "customer-repping" distributors placed
orders with the Company in response to end-user customer orders. The Company
shipped these products directly to the end-user customer (usually a hospital) at
the direction of the distributor. Title (but not the physical product) passed to
the distributor, and the distributor paid the Company and was responsible for
billing and collecting from the end customer. The distributor's obligation to
the Company was not contingent on its ability to collect from its end customer.
As of November 2005, the JARIT business now sells these products directly to the
end-user hospitals, and the Company has the credit risk for these customers.

The key terms applicable to "customer-repping" distributors included: (i) the
right to purchase product upon delivery of a properly executed purchase order;
(ii) title passing to either the customer or the distributor once the product
left the Company's warehouse (when product was shipped FOB shipping point or ex
works) or upon verification of receipt by the customer (when product was shipped
FOB destination); and (iii) payment due in 30 to 90 days. The Company generally
accepts returns on account of defective product, shipment in error or
mis-ordering at



SEPTEMBER 8, 2006
PAGE 3



the Company's sole discretion. The recognition of revenue in these relationships
occurred when title passed.

2.  FOREIGN STOCKING DISTRIBUTORS

Independent foreign stocking distributors market and sell the Company's products
in those countries where the Company does not have a direct sales force or
"customer-repping" distributors. Sales to stocking distributors resulted in
approximately $45 million, or 16% of product revenues in 2005, $33 million, or
14% of product revenues in 2004, and $21 million, or 13% of product revenues in
2003. Additionally, sales to the single largest stocking distributor customer
represented less than 2% of product revenues in each of 2005, 2004 and 2003.

The Company has formal contracts with certain of its foreign stocking
distributors. The Company's sales to the majority of foreign stocking
distributors are governed by standard sales terms which are contained in sales
invoices and in the Company's catalogue which are reflective of custom and
practice. The key terms applicable to foreign stocking distributors include: (i)
the right of the distributor to purchase product upon delivery of a properly
executed purchase order; (ii) title passing to the distributor (a) once the
product leaves the Company's warehouse (FOB shipping point or ex works) or (b)
upon verification of receipt when shipped FOB destination; (iii) payment due in
30 to 90 days; and (iv) a right to return product within 90 days (120 days in
the case of one distributor) with the Company's prior authorization. On
infrequent occasions, the Company has accepted returns after the expiration of
the 90- or 120-day period at its sole discretion.

3.  OTHER MEDICAL DEVICE COMPANIES

The Company supplies product under distribution agreements to various
fully-integrated medical device companies. Each of the Company's agreements with
these entities is individually negotiated. The key terms typically include (i)
annual minimum purchase requirements of specified proprietary products at
specified prices; (ii) title passing to the medical device company once the
Company delivers the product to the carrier (FOB shipping point or ex works);
(iii) payment due in 30 to 60 days; and (iv) a right to return only products or
shipments of products that do not conform to product or purchase order
specifications.

2005 RETURN STATISTICS

The total amount of products returned was 1.8% of total consolidated product
revenues in 2005.

DISCUSSION

In accordance with SAB 104, revenue is generally realized or realizable and
earned when all of the following criteria are met:

     o   Persuasive evidence of an arrangement exists,

     o   Delivery has occurred or services have been rendered,

     o   The seller's price to the buyer is fixed or determinable, and



SEPTEMBER 8, 2006
PAGE 4



     o   Collectibility is reasonably assured.

Virtually all of the Company's revenue-generating activities relate to the
shipment of product. Revenues from sales of products are recognized when title
and risk of loss passes to the customer. This occurs at the time of shipping
when products are shipped FOB shipping point or after verification of delivery
if shipped FOB destination. Each transaction with end-user customers or
"customer repping" distributors is reflected in a purchase order, and each
transaction with the other distributors described above is evidenced by either a
contract or the distributor's purchase order accepted by the Company according
to its general sales terms, as well as the sales invoice which includes the
sales terms. There is no significant customer acceptance or other conditions
that prevent the Company from recognizing revenue upon shipment (when product is
shipped FOB shipping point or ex works) or upon verification of receipt by the
customer (when product is shipped FOB destination). The sales invoice issued to
the customer contains the Company's price, and reasonable estimates are
determined for sales returns at the time of sale. These estimates were based on
years of historical sales returns and other known factors. The provisions were
recorded as a reduction to revenues. A reserve for uncollectible accounts on a
specific customer basis is also maintained.

Under paragraph 6 of SFAS 48, revenue from a sales transaction to the Company's
distributors may be recognized at the time of sale only if all of the following
conditions are met:

         a.       THE SELLER'S PRICE TO THE BUYER IS SUBSTANTIALLY FIXED OR
                  DETERMINABLE AT THE DATE OF SALE. The Company's prices are set
                  forth on a sales invoice and are not subject to any
                  adjustment, reduction or offset after shipment.

         b.       THE BUYER HAS PAID THE SELLER, OR THE BUYER IS OBLIGATED TO
                  PAY THE SELLER AND THE OBLIGATION IS NOT CONTINGENT ON RESALE
                  OF THE PRODUCT. The customer's obligation to pay arises when
                  title and risk of loss passes and is not contingent on the
                  customer's resale of the product.

         c.       THE BUYER'S OBLIGATION TO THE SELLER WOULD NOT BE CHANGED IN
                  THE EVENT OF THEFT OR PHYSICAL DESTRUCTION OR DAMAGE OF THE
                  PRODUCT. With respect to goods shipped FOB shipping point or
                  ex works, the risk of loss passes to the customer at the time
                  of shipment. With respect to goods shipped FOB destination,
                  the risk of loss passes at the time of delivery. In cases
                  where the goods are shipped FOB destination, the Company has a
                  procedure to review shipping documents at period ends to defer
                  revenue recognition if the goods have not been delivered prior
                  to that period end date. The buyer's obligation or risk of
                  loss would not change in the event of theft or physical
                  destruction or damage of the product.

         d.       THE BUYER ACQUIRING THE PRODUCT FOR RESALE HAS ECONOMIC
                  SUBSTANCE APART FROM THAT PROVIDED BY THE SELLER. All of the
                  Company's distributors are independent entities actually
                  engaged in business. Since the Company had more than 600
                  active distributors in 2005, it is difficult to broadly
                  characterize them by size or financial strength. However, none
                  of them were affiliates of the Company.



SEPTEMBER 8, 2006
PAGE 5



         e.       THE SELLER DOES NOT HAVE SIGNIFICANT OBLIGATIONS FOR FUTURE
                  PERFORMANCE TO DIRECTLY BRING ABOUT RESALE OF THE PRODUCT BY
                  THE BUYER. The Company has no obligation to facilitate
                  distributor sales. Once product was shipped to a distributor,
                  the Company did not retroactively adjust, reduce or offset the
                  price of such product in order to facilitate distributor
                  sales.

         f.       THE AMOUNT OF FUTURE RETURNS CAN BE REASONABLY ESTIMATED
                  (PARAGRAPH 8). The Company's sales consist of a large volume
                  of relatively homogenous transactions, and, as noted above,
                  the maximum return period is only 90 days (120 days in the
                  case of one distributor) subject to minimal exceptions as
                  noted above. Substantial history (directly and including
                  historical information for acquired companies) with sales of
                  each of the Company's products and actual returns against
                  those sales permits reasonable estimates of returns.

Consistent with sales to all of the Company's customers including distributors,
revenues are recorded net of provisions for estimated returns, which are
established at the time of the sale as all of the conditions in paragraph 6 of
SFAS 48 have been met at that time.

The Company recognizes that its accounting policy disclosure regarding sales
returns is included under the heading "Trade Accounts Receivable, Allowances For
Doubtful Accounts and Sales Returns" and will disclose this policy under the
"Revenue Recognition" heading in future filings.

         ACCRUE FOR LOSS CONTINGENCIES ON A GROSS BASIS BEFORE CONSIDERATION OF

         SFAS 5.

RESPONSE TO COMMENT 2

The Company has historically accrued for loss contingencies in accordance with
SFAS 5; that is, when it is deemed probable that a loss has been incurred and
that loss is estimable. The amounts accrued are based on the full amount of the
estimated loss, and do not include an estimate for legal fees expected to be
incurred in connection with the loss contingency. The Company consistently
accrues legal fees expected to be incurred in connection with loss contingencies
as those fees are incurred by outside counsel as a period cost, as permitted by
EITF Topic D-77.

The Company's experience with loss contingencies that are covered by insurance
or otherwise indemnified has been minimal. During the three-year period ended
December 31, 2005, the Company was named as a party in only six loss
contingencies that were covered by insurance. The status of these six loss
contingencies is as follows:

     o   Two of these matters remain outstanding. Management, in consultation
         with legal counsel, has not deemed it probable that a loss has been
         incurred in either of these matters. Accordingly, the Company has not
         recorded any liability for these matters.



SEPTEMBER 8, 2006
PAGE 6



     o   In one of these matters, the Company was dismissed from the claim and
         incurred no damages. At no point did management, in consultation with
         legal counsel, deem it probable that a loss had been incurred in this
         matter. Accordingly, the Company did not record any liability for this
         matter.

     o   In the remaining three matters, the Company reached a settlement with
         the counterparty.

         -    In one of these matters, the Company paid the settlement without
              submitting a claim to the insurance carrier. When management, in
              consultation with legal counsel, deemed it probable that a loss
              had been incurred and that loss was estimable, the Company
              properly recorded a liability in accordance with SFAS 5 for the
              gross amount of the estimated damages.

         -    In the other two settled matters, each of which was settled in
              February 2006 for $200,000 and $5,000, respectively, the
              settlement amounts were fully covered and paid for by the
              Company's insurance carrier on March 3, 2006 and May 24, 2006,
              respectively. There was no deductible applicable in either of
              these matters, and the loss had not been deemed probable by
              management prior to the February 2006 settlement dates. The
              Company did not record a gross liability and receivable in the
              December 31, 2005 financial statements for these subsequent events
              due to the fact that the amounts were clearly immaterial in
              relation to the Company's total assets, total equity and total
              revenues ($448.4 million and $289.8 million at December 31, 2005
              and $277.9 million for the twelve months then ended,
              respectively). This matter did not have any affect on the
              Company's statement of operations.

The Company will expand its disclosures in future filings to clarify that it
accrues for loss contingencies on a gross basis before considering insurance
proceeds and to disclose the Company's policy regarding the accrual for legal
fees.

RESPONSE TO COMMENT 3

Integra believes that the presentation of non-GAAP financial measures in the
form of an adjusted statement of operations provides important supplemental
information to management and investors regarding non-cash expenses and
financial and business trends relating to the




SEPTEMBER 8, 2006
PAGE 7



Company's financial condition and results of operations. Management uses
non-GAAP financial measures in the form of an adjusted statement of operations
when evaluating operating performance because the Company believes that the
inclusion or exclusion of certain items, for which the amounts and/or timing may
vary significantly depending upon the Company's acquisition and restructuring
activities, provides a supplemental measure of the Company's operating results
that facilitates comparability of the Company's operating performance from
period to period, against the Company's business model objectives, and against
other companies in the Company's industry. The Company has chosen to provide
this information to investors so they can analyze the Company's operating
results in the same way that management does and use this information in their
assessment of the valuation of the Company.

Internally, non-GAAP financial measures in the form of an adjusted statement of
operations are used by management for purposes of:

o        supplementing the financial results and forecasts reported to the
         Company's board of directors;

o        evaluating, managing and benchmarking the operating performance of the
         Company;

o        establishing internal operating budgets;

o        comparing performance with internal forecasts and targeted business
         models; and

o        evaluating and valuing potential acquisition candidates.

The Company has disclosed only those non-GAAP financial measures utilized by
management internally which management wished to highlight for investors with
appropriate reconciliations for each measure. On a prospective basis, the
Company intends to highlight only two non-GAAP financial measures currently
presented in the adjusted statement of operations (net income and diluted
earnings per share, both on an adjusted basis). As a result, the Company will
not include an adjusted statement of operations in future earnings releases. On
a prospective basis, the Company will provide all disclosures required by Item
10(e)(1)(i) of Regulation S-K, including the reasons why management uses the
non-GAAP financial measure and why management believes the presentation of each
of the individual non-GAAP measures provides useful information to investors.

4.       UNDER REGULATION G AND ITEM 10(e)(I)(i) OF REGULATION S-K, YOU MUST
         ACCOMPANY EACH NON-GAAP FINANCIAL MEASURE WITH THE FOLLOWING:

         o        A PRESENTATION, WITH EQUAL OR GREATER PROMINENCE, OF THE MOST
                  DIRECTLY COMPARABLE FINANCIAL MEASURE OR MEASURES CALCULATED
                  AND PRESENTED IN ACCORDANCE WITH GENERALLY ACCEPTED ACCOUNTING
                  PRINCIPLES (GAAP);

         o        A RECONCILIATION (BY SCHEDULE OR OTHER CLEARLY UNDERSTANDABLE
                  METHOD), WHICH SHALL BE QUANTITATIVE FOR HISTORICAL NON-GAAP
                  MEASURES PRESENTED, AND QUANTITATIVE, TO THE EXTENT AVAILABLE

         o        A STATEMENT DISCLOSING THE REASONS WHY THE REGISTRANT'S
                  MANAGEMENT BELIEVES THAT PRESENTATION OF THE NON-GAAP

                  THE NON-GAAP FINANCIAL MEASURE.

         THIS APPLIES TO EVERY AMOUNT THAT YOU PRESENT AS A NON-GAAP MEASURE
         INCLUDING SHARES AND PER SHARE AMOUNTS. WHEN YOU PRESENT A STATEMENT OF
         NON-GAAP MEASURES, PLEASE NOTE THAT EACH MEASURE IN THE STATEMENT
         REPRESENTS A NON-GAAP MEASURE FOR WHICH YOU SHOULD PROVIDE THE REQUIRED
         DISCLOSURES. THE RECONCILIATION SHOULD BOTH IDENTIFY AND QUANTIFY EACH
         RECONCILING ADJUSTMENT INCLUDED IN THE NON-GAAP MEASURE. THE STATEMENT
         OF REASONS SHOULD ADDRESS EACH OF THE ADJUSTING ITEMS INCLUDED IN THE
         NON-GAAP MEASURE TO THE EXTENT NECESSARY TO EXPLAIN THE REASONS WHY
         MANAGEMENT BELIEVES THE MEASURE IS USEFUL. THE DISCUSSION OF YOUR
         REASONS FOR PROVIDING THE MEASURE SHOULD BE SPECIFIC AND NOT BROAD OR

         NON-GAAP MEASURE YOU PRESENT. PLEASE REVISE FUTURE FILINGS TO COMPLY
         AND PROVIDE US WITH A SAMPLE OF YOUR PROPOSED DISCLOSURE.

RESPONSE TO COMMENT 4

On a prospective basis, the Company will provide all disclosures required by
Item 10(e)(1)(i) of Regulation S-K for each non-GAAP measure presented. Sample
disclosure is provided on Annex A to this letter and contemplates certain
disclosures in a Current Report on Form 8-K which would furnish an earnings
press release which contains hypothetical non-GAAP financial measures. The
sample disclosure reflects proposed language for both documents that meets the
requirements of Item 10(e)(1)(i) of Regulation S-K. The specific non-GAAP
financial measures provided in Annex A and the adjustments used to calculate

actual disclosures would be revised and expanded accordingly.

5.       WHILE THERE IS NO per se PROHIBITION AGAINST REMOVING A RECURRING ITEM,
         YOU MUST MEET THE BURDEN OF DEMONSTRATING THE USEFULNESS OF ANY MEASURE
         THAT EXCLUDES RECURRING ITEMS, ESPECIALLY IF THE NON-GAAP FINANCIAL
         MEASURE IS USED TO EVALUATE PERFORMANCE. WHETHER A NON-GAAP FINANCIAL
         MEASURE THAT ELIMINATES A RECURRING ITEM OR ITEMS FROM THE MOST
         DIRECTLY COMPARABLE GAAP FINANCIAL MEASURE IS ACCEPTABLE DEPENDS ON ALL
         OF THE FACTS AND CIRCUMSTANCES. HOWEVER, IF THERE IS A PAST PATTERN OF
         THE CHARGES, NO ARTICULATED DEMONSTRATION THAT SUCH CHARGES WILL NOT
         CONTINUE AND NO OTHER UNUSUAL REASON THAT A COMPANY CAN SUBSTANTIATE TO
         IDENTIFY THE SPECIAL NATURE OF THE CHARGE, IT WOULD BE DIFFICULT FOR A
         COMPANY TO MEET THE BURDEN OF DISCLOSING WHY SUCH A NON-GAAP FINANCIAL
         MEASURE IS USEFUL TO INVESTORS. IN SUCH CIRCUMSTANCES, ITEM 10(e) OF
         REGULATION S-K WOULD NOT PERMIT THE USE OF THE NON-GAAP FINANCIAL
         MEASURE AND SIMILAR CONSIDERATIONS MAY APPLY UNDER ITEM 12 OF FORM 8-K.

         USING A SHARE FIGURE THAT IS PRESENTED ON A DILUTED BASIS IN ACCORDANCE
         WITH GAAP, SPECIFICALLY NON-GAAP ADJUSTED DILUTED EARNINGS PER SHARE,
         YOU SHOULD CONSIDER WHETHER THIS PRESENTATION COMPLIES WITH THE
         REQUIREMENT OF REGULATION G THAT A REGISTRANT, OR A PERSON ACTING ON
         ITS BEHALF, SHALL NOT MAKE PUBLIC A NON-GAAP FINANCIAL MEASURE THAT,
         TAKEN TOGETHER WITH THE INFORMATION ACCOMPANYING THAT MEASURE, CONTAINS

         FACT NECESSARY IN ORDER TO MAKE THE PRESENTATION OF THE NON-GAAP
         FINANCIAL MEASURE, IN LIGHT OF THE CIRCUMSTANCES UNDER WHICH IT IS
         PRESENTED, NOT MISLEADING. SEE RULE 100 OF REGULATION G.

RESPONSE TO COMMENT 6

In calculating adjusted net income and adjusted diluted earnings per share, one
of the adjustments was to add back all equity-based compensation expense
determined in accordance with FASB 123R to be more comparable with prior years.
In order to make the 2006 presentation more comparable to prior years, the
calculation of weighted average shares outstanding on a diluted basis had to be
conformed as well. In calculating diluted EPS, the dilutive effect of restricted
stock and stock options on the denominator is determined through application of
the treasury stock method, and unearned equity-based compensation is one factor
that is used to calculate assumed share repurchases under the treasury stock
method. Because the unrecognized equity-based compensation expense under FAS
123R is higher than if no equity-based compensation charges are assumed (which
is how the Company calculates adjusted net



SEPTEMBER 8, 2006
PAGE 10



income), the number of shares that are included in the denominator of diluted
EPS when applying FAS 123R is less than the number of shares that are included
in the Company's method of reporting adjusted earnings per share (i.e. in order
to be consistent, since all equity-based compensation expense was added back in
the calculation of adjusted net income, the weighted average shares used to
calculate adjusted earnings per share were also adjusted so that no unearned
equity-based compensation is considered in the treasury stock method). As was
disclosed in the release, the difference in the weighted average shares was
138,000 as compared to total weighted average shares outstanding on a diluted
basis as reported of approximately 33,800,000.

Because the Company will add back the effects of all equity-based compensation
costs in its adjusted net income going forward to promote more consistency with
the prior year's presentation, management believes that the determination of
weighted average shares outstanding for purposes of calculating adjusted
earnings per diluted share should also continue to be adjusted as described
above.

PROPOSED FORM OF DISCLOSURE FOR FUTURE CURRENT REPORTS ON FORM 8-K:

ITEM 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION

The information in this Current Report, including the accompanying exhibit, is
being furnished and shall not be deemed filed for the purposes of Section 18 of
the Securities Exchange Act of 1934, as amended, or otherwise subject to the
liabilities of that Section. The information in this Current Report shall not be
incorporated by reference into any registration statement or other document
filed pursuant to the Securities Act of 1933, as amended, regardless of any
general incorporation language contained in such filing.

On __________, 2006, Integra LifeSciences Holdings Corporation issued a press
release announcing the unaudited financial results for its third quarter ended
September 30, 2006. A copy of the press release is furnished herewith as Exhibit
99.1 and is incorporated by reference herein.

DISCUSSION OF ADJUSTED FINANCIAL MEASURES

In addition to our GAAP results, we provide adjusted net income and adjusted
earnings per diluted share. Adjusted net income consists of net income excluding
equity-based compensation charges, acquisition-related charges, facility
consolidation, manufacturing transfer and system integration charges and certain
employee termination and related costs. Adjusted earnings per diluted share is
calculated by dividing adjusted net income by adjusted diluted weighted average
shares outstanding. Because all equity-based compensation expense is added back
in the calculation of adjusted net income, the calculation of diluted weighted
average shares outstanding is adjusted to exclude the benefits of unearned
equity-based compensation costs attributable to future services and not yet
recognized in the financial statements. These unearned equity-based compensation
costs are treated as proceeds assumed to be used to repurchase shares in the
calculation of GAAP diluted weighted average shares outstanding.

Integra believes that the presentation of adjusted net income and adjusted
earnings per diluted share provides important supplemental information to
management and investors regarding non-cash expenses and financial and business
trends relating to the Company's financial condition and results of operations.
Management uses non-GAAP financial measures in the form of adjusted net income
and adjusted earnings per diluted share when evaluating operating performance
because we believe that the inclusion or exclusion of the items described below,
for which the amounts and/or timing may vary significantly depending upon the
Company's acquisition and restructuring activities, provides a supplemental
measure of our operating results that facilitates comparability of our operating
performance from period to period, against our business model objectives, and
against other companies in our industry. We have chosen to provide this
information to investors so they can analyze our operating results in the same
way that management does and use this information in their assessment of our
core business and the valuation of our Company.



SEPTEMBER 8, 2006
PAGE 13



Internally, adjusted net income and adjusted earnings per diluted share are
significant measures used by management for purposes of:

o        supplementing the financial results and forecasts reported to the
Company's board of directors;

o        evaluating, managing and benchmarking the operating performance of the
Company;

o        establishing internal operating budgets;

o        determining compensation under bonus or other incentive programs;

o        enhancing comparability from period to period;

o        comparing performance with internal forecasts and targeted business
models; and

o        evaluating and valuing potential acquisition candidates.

Adjusted net income reflects net income adjusted for the following items:

o EQUITY-BASED COMPENSATION. Equity-based compensation relates primarily to
employee stock options and restricted stock units issued by the Company.
Although recurring in nature, equity-based compensation expense is heavily
influenced by management decisions regarding equity-based awards that were
granted at a time when different accounting rules applied to such awards and is
a non-cash expense that varies in amount from period to period and is affected
by market forces that are difficult to predict and are not within the control of
management, such as the price of our common stock. Accordingly, management
excludes this item from its internal operating forecasts and models and as it
assesses the Company's performance. Management believes that exclusion of this
item is consistent with the guidance in Staff Accounting Bulletin No. 107.

o ACQUISITION-RELATED CHARGES. Acquisition-related charges include in-process
research and development charges and inventory fair value purchase accounting
adjustments. Inventory fair value purchase accounting adjustments consist of the
increase to cost of goods sold that occur as a result of expensing the "step up"
in the fair value of inventory that we purchased in connection with acquisitions
as that inventory is sold during the financial period. Although recurring given
the ongoing character of our acquisition program, these acquisition-related
charges are not factored into the evaluation of our performance by management
after completion of acquisitions because they are of a temporary nature, they
are not related to our core operating performance and the frequency and amount
of such charges vary significantly based on the timing and magnitude of our
acquisition transactions as well as the level of inventory on hand at the time
of acquisition.



SEPTEMBER 8, 2006
PAGE 14



o FACILITY CONSOLIDATION, MANUFACTURING TRANSFER AND SYSTEM INTEGRATION CHARGES.
These charges, which include employee termination and other costs associated
with exit or disposal activities and costs associated with the worldwide
implementation of a single enterprise resource planning system, result from
rationalizing our existing manufacturing, distribution and administrative
infrastructure. Many of these cost-saving and efficiency-driven activities are
identified as opportunities in connection with acquisitions that provide the
Company with additional capacity or economies of scale. Although recurring in
nature given management's ongoing review of the efficiency of our manufacturing,
distribution and administrative facilities and operations, management excludes
these items when evaluating the operating performance of the Company because the
frequency and amount of such charges vary significantly based on the timing and
magnitude of the Company's rationalization activities and are, in some cases,
dependent upon opportunities identified in acquisitions, which also vary in
frequency and magnitude.

o EMPLOYEE TERMINATION AND RELATED COSTS. Employee termination and related costs
consist of charges related to significant reductions in force that are not
initiated in connection with facility consolidations or manufacturing transfers.
Management excludes these items when evaluating Integra's operating performance
because these amounts do not affect our core operations, given the large-scale
and one-time nature of these activities.

o INCOME TAX EXPENSE (BENEFIT). Income tax expense is adjusted by the amount of
additional tax expense or benefit that the Company estimates that it would
record if it used non-GAAP results instead of GAAP results in the calculation of
its tax provision. Such additional tax expense or benefit is calculated at the
statutory rate.

The calculation of adjusted earnings per diluted share is further adjusted for
the following item:

o As noted above, in calculating adjusted net income, one of the Company's
adjustments is to add back all equity-based compensation expense determined in
accordance with FASB 123R to be more comparable to prior years. In order to make
the 2006 presentation more comparable to prior years, the calculation of
weighted average shares outstanding on a diluted basis had to be conformed as
well. In calculating diluted EPS, the dilutive effect of restricted stock and
stock options on the denominator is determined through application of the
treasury stock method, and unearned equity-based compensation is one factor that
is used to calculate assumed share repurchases under the treasury stock method.
Because the unrecognized equity-based compensation expense under FAS 123R is
higher than if no equity-based compensation charges are assumed (which is how we
calculate adjusted net income), the number of shares that are included in the
denominator of diluted EPS when applying FAS 123R is less than the number of
shares that are included in our method of reporting adjusted earnings per share
(i.e. in order to be consistent, since all equity-based compensation expense was
added back in the calculation of adjusted net income, the weighted average
shares used to calculate adjusted earnings per share were also adjusted so that
no unearned equity-based compensation is considered in the treasury stock
method). As was disclosed in the release, the difference in the weighted average
shares was 138,000 as compared to total weighted average shares outstanding on a
diluted basis as reported of approximately 33.8 million. Our calculation of
adjusted earnings per diluted share is based on a different number of shares
than GAAP earnings per share.



SEPTEMBER 8, 2006

Adjusted net income and adjusted earnings per diluted share are not calculated
in accordance with GAAP, and should be considered supplemental to, and not as a
substitute for, or superior to, financial measures calculated in accordance with
GAAP. Non-GAAP financial measures have limitations in that they do not reflect
all of the costs or benefits associated with the operations of the Company's
business as determined in accordance with GAAP. As a result, you should not
consider these measures in isolation or as a substitute for analysis of
Integra's results as reported under GAAP. Integra expects to continue to incur
expenses of a nature similar to the non-GAAP adjustments described above, and
exclusion of these items from its adjusted net income should not be construed as
an inference that these costs are unusual, infrequent or non-recurring. Some of
the limitations in relying on adjusted net income and adjusted earnings per
diluted share are:

o Adjusted net income does not include equity-based compensation expense
related to equity awards granted to our workforce. Our equity incentive plans
are important components of our employee incentive compensation arrangements and
are reflected as expenses in our GAAP results in accordance with Statement of
Financial Accounting Standards No. 123R, Share-Based Payment, commencing with
the first quarter of 2006. While we include the dilutive impact of such equity
awards in weighted average shares outstanding, the expense associated with
equity -based awards is excluded from adjusted net income.

o Integra periodically acquires other companies or businesses, and we expect to
continue to incur acquisition-related expenses and charges in the future. These
costs can directly impact the amount of the Company's available funds or could
include costs for aborted deals which may be significant and reduce GAAP net
income.

o Although the charges related to the restructuring of our operations occur on
a sporadic basis, they may recur in the future and they are cash charges that
reduce our available cash. There is no assurance that we will not incur other
restructuring and additional one-time expenditures in the future.

o All of the adjustments have been tax effected at Integra's actual tax rates.
Depending on the nature of the adjustments and the tax treatment of the
underlying items, the effective tax rate on adjusted income could differ
significantly from the effective tax rate on GAAP income.

In the financial statements portion of its earnings press release for the third
quarter of 2006, which is attached hereto as Exhibit 99.1, the Company has
included a reconciliation of GAAP to non-GAAP net income and non-GAAP earnings
per diluted share used by management for the three and nine months ended
September 30, 2006 and 2005.

DISCUSSION OF ADJUSTED FINANCIAL MEASURES

Adjusted net income consists of net income excluding equity-based compensation
charges, acquisition-related charges, facility consolidation, manufacturing
transfer and system integration charges and certain employee termination and
related costs. Adjusted earnings per diluted share is calculated by dividing
adjusted net income by adjusted diluted weighted average shares outstanding.
Because all equity-based compensation expense is added back in the calculation
of adjusted net income, the calculation of diluted weighted average shares
outstanding is adjusted to exclude the benefits of unearned equity-based
compensation costs attributable to future services and not yet recognized in the
financial statements. These unearned equity-based compensation costs are treated
as proceeds assumed to be used to repurchase shares in the calculation of GAAP
diluted weighted average shares outstanding.

Integra believes that the presentation of adjusted net income and adjusted
earnings per diluted share provides important supplemental information to
management and investors regarding non-cash expenses and financial and business
trends relating to the Company's financial condition and results of operations.
For further information regarding why Integra believes that these non-GAAP
measures provide useful information to investors, the specific manner in which
management uses these measures, and some of the limitations associated with the
use of these measures, please refer to the Company's Current Report on Form 8-K
regarding this earnings press release filed today with the Securities and
Exchange Commission. The section of the Company's report is available on the
SEC's website at www.sec.gov or on our website at www.Integra-LS.com.
