         NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1.  BASIS OF PRESENTATION

         The accompanying unaudited condensed consolidated financial statements
of Lason, Inc. (together with its subsidiaries, "Lason" or the "Company") have
been prepared in conformity with generally accepted accounting principles for
interim financial information and with the instructions for Form 10-Q and Rule
10-01 of Regulation S-X. Accordingly, such interim financial statements do not
include all of the information and footnotes required by generally accepted
accounting principles for complete consolidated financial statements.

         In the opinion of management, all necessary adjustments (consisting of
normal recurring adjustments) considered necessary for a fair presentation have
been included. The operating results for the nine month period ended September
30, 1999 are not necessarily indicative of the results to be expected for the
year ending December 31, 1999.

         For further information, refer to the consolidated financial statements
and notes thereto included in the Company's Annual Report on Form 10-K for the
year ended December 31, 1998 filed with the Securities and Exchange Commission
on March 31, 1999.

         Certain reclassifications have been made to the consolidated financial
statements for 1998 to conform to the 1999 presentation.

         In the unaudited condensed consolidated financial statements previously
presented and filed with the Securities and Exchange Commission on Form 10-Q on
November 15, 1999, the acquisition of MR Group plc ("M-R") was accounted for
using the pooling of interests method of accounting. In December 1999, Lason
took certain actions which require a change to the purchase method of accounting
for the acquisition of M-R. The accompanying unaudited condensed consolidated
financial statements, which are included in Form 10-Q/A, are restated to present
the acquisition of M-R using the purchase method of accounting. All other
information is as previously filed, unless otherwise indicated. See Note 2.

NOTE 2.  MERGERS AND ACQUISITIONS

         On June 30, 1999, the Company completed its merger with M-R Group plc
("M-R"), a leading document and data management company headquartered in the
United Kingdom. In connection with the merger, the Company issued 3,071,863 new
shares of its common stock in exchange for all of the outstanding common stock
of M-R, including 47,222 shares issued in connection with the settlement of
certain M-R stock options (the "Executive Options"). Pursuant to the merger
agreement, M-R shareholders received 5.376 new shares of Lason common stock for
every 100 M-R shares held for a total value of approximately $152.4 million as
of June 30, 1999.

         In connection with the Executive Options, M-R previously established a
trust that purchased shares of M-R common stock on the open market. Such shares
were to be issued to employees upon exercise of their respective individual
stock options. Such shares were converted into approximately 112,000 shares of
Lason common stock as part of the aforementioned 3,071,863 shares of Lason
common stock issued. The June 30, 1999 value of such shares of common stock
issued is recorded as treasury stock in the Company's condensed consolidated
financial statements.


                                        5

         Under terms of the merger agreement, certain M-R stock options (the
"Staff Options") were exchanged for options to receive 39,540 shares of Lason
common stock, calculated at the same exchange ratio discussed above. The Staff
Options must be exercised, in accordance with the terms of the M-R option plan,
on or before December 29, 1999 or the options expire. A total of 8,064 such
shares were issued in the three month period ended September 30, 1999.

         In connection with the M-R merger, the Company recorded approximately
$7.8 million of merger-related expenses which were charged to operations during
the second quarter of 1999, related to discontinued leases, the consolidation of
facilities, severance and other related expenses for Lason facilities which were
closed or consolidated into M-R facilities. For the business that have had
facilities closed or consolidated with other facilities, the tangible assets to
be disposed of have been written down to their estimated fair value, less cost
of disposal. In addition, as a result of the consolidation of approximately 21
facilities, approximately 410 employees have been separated from the Company as
of September 30, 1999. The remaining accrual for such costs at September 30,
1999 is $500,000, which is expected to be fully used by the end of the first
quarter of 2000.

         During the nine months ended September 30, 1999, the Company completed
several additional acquisitions, the most significant of which were: Vetri
Systems, Inc. and its affiliate Vetri Software India, Ltd., Bonner & Moore
Computing Company, a division of Bonner & Moore Associates, Inc., the Texas
division of Compex Legal Services, MSI Digital Imaging Solutions, Inc.,
Cover-All Computer Holdings Company and its affiliates, MSCI, Inc., Crest
Information Technologies, Inc., Marketing Associates, Inc., and Addressing
Services Company, Inc.

         Aggregate consideration for all acquisitions completed during the first
nine months of 1999 (the "1999 Acquisitions"), excluding liabilities assumed,
was approximately $279.3 million, consisting of approximately $110.5 million in
cash, 3,377,206 shares of the Company's common stock valued at approximately
$166.9 million and debentures convertible into 32,532 shares of the Company's
common stock valued at approximately $1.9 million at the date of acquisition.

         For the 1999 Acquisitions, 270,705 shares of the Company's common stock
valued at approximately $13.0 million on the transaction date, and approximately
$1.7 million in cash are being held in escrow to indemnify the Company if
contingencies set forth in the purchase agreements occur within specified time
frames ranging from 12 to 24 months from the date of acquisition. In addition,
$4.2 million of the aggregate cash will be paid only if certain contingencies
are met. Finally, certain of the purchase agreements provide for an increase to
the purchase price if operating income of the acquired business exceeds targeted
levels. The maximum amount of additional purchase price which may be recorded
should such targets be achieved for the 1999 Acquisitions is approximately
$115.0 million. Purchase price contingencies, if any, will be recorded as an
adjustment to the purchase price when the related contingency is resolved.

         Each of the 1999 Acquisitions was accounted for as a purchase. The
results of operations for the three and nine month periods ended September 30,
1999 include the results of operations for each of the acquisitions since the
date of their respective acquisition.

         The purchase price for the 1999 Acquisitions was allocated to the
assets acquired and liabilities assumed based on the estimated fair values at
the date of acquisition. The excess of the aggregate purchase price over the
fair values of assets acquired and liabilities assumed has been allocated to
goodwill and is being amortized on a straight-line method over 30 years. The
allocation of the excess purchase price is based on preliminary estimates and
assumptions, and is subject to revision upon final determination of the fair
market value of the net assets acquired. Management does not expect the final
allocations to differ materially from the preliminary estimates.

     In October 1999, the Company purchased all of the outstanding common stock
of Atlantic Document Centers, Inc. for aggregate consideration of $6.0 million
consisting of approximately $5.1 million in cash and 19,537 shares of the
Company's common stock valued at approximately $0.9 million

NOTE 3.  LONG-TERM DEBT

     In August of 1999, the Company amended and restated its credit agreement
with its lenders. Borrowings under the amended credit agreement are expected to
be used to finance additional acquisitions of businesses, working capital,
capital expenditures and other corporate purposes. Such borrowings are secured
by guarantees of certain of the Company's subsidiaries, as well as pledges of
the capital stock of certain subsidiaries. Interest on amounts outstanding is
calculated based on interest rates determined at the time of borrowing.
Borrowings bear interest at rates ranging from a Eurodollar rate plus a maximum
of 2.00% ( 6.87% as of September 30, 1999) or a base percentage rate plus a
maximum of 0.50% ( 8.25% at September 30, 1999), at the Company's election at
the time of borrowing. The credit agreement contains restrictions on
acquisitions, disposition of assets, and the incurrance of other liabilities and
contains certain financial ratio covenants.

     The amended credit agreement includes a revolving credit facility of $150
million, which the Company may increase to up to $250 million subject to certain
limitations. A portion of the revolving credit facility of up to $50 million is
available to the Company for borrowings in Euro, British pound sterling,
Canadian dollar and other freely traded currencies to be agreed upon with the
lenders. Lason is not required to make principal payments until final maturity
in 2004.

         The amendment to the credit agreement also added a term loan facility
of $150 million. Quarterly principal payments commence May 2000, with final
maturity August 2004, as follows (in thousands):

Prior to the amendment, the credit agreement provided for revolving loans of up
to $200 million, which the Company supplemented with an agreement providing for
revolving credit loans of up to an additional $50 million. Borrowings under the
credit agreement were collateralized by substantially all of the Company's
assets before the recent amendment.

NOTE 4.  COMPREHENSIVE INCOME

     The assets and liabilities of foreign subsidiaries are translated into
United States dollars using period end exchange rates while income statements
are translated using average exchange rates during the periods. Differences
arising from the translation of assets and liabilities in comparison with the
translation of the previous periods are included as a separate component of
Stockholders' Equity. The net accumulated foreign currency translation
adjustment is approximately $5.9 million at September 30, 1999, and zero at
December 31, 1998.

     The components of other comprehensive income are as follows (in thousands):

NOTE 6. SEGMENT AND RELATED INFORMATION

        SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information" was issued in June 1997 and is effective for financial statements
issued after December 15, 1998. The statement requires the Company to report
certain information about its operating segments.

        For years prior to 1998, the Company was managed as one operating
segment. Beginning in 1998, the Company's reportable segments consist of groups
of business units that are organized geographically. Each of the Company's
geographic regions has a separate management team and infrastructure, and offers
different combinations of the Company's services. The Company evaluates the
performance of its operating segments based on income before income taxes and
net corporate interest expense. Intersegment sales and transfers are not
significant.

        The following table presents summarized financial information for the
Company's reportable segments for the three and nine months ended September 30,
1999 and 1998 (in thousands). The "Other" balances include corporate related
items, results of insignificant operations and, as it relates to segment profit
(loss), income and expenses not allocated to reportable segments. The
international segment was previously included in "other" but is now shown
separately as certain quantitative thresholds under SFAS No. 131 have now been
met. The international segment includes the United Kingdom, Canada and Mexico.
Prior periods have been restated accordingly. Additionally, prior periods have
been restated for the reallocation of certain business units among regions
during 1999.

        OF OPERATIONS

     The following discussion contains forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933, as amended, and Section
21E of the Securities Exchange Act of 1934, as amended. Those statements include
statements regarding the intent, belief or current expectations of the Company
and its management. Prospective investors are cautioned that any such
forward-looking statements are not guarantees of future performance and involve
a number of risks and uncertainties, and that actual results could differ
materially from those indicated by such forward-looking statements. Among the
important factors that could cause actual results to differ materially from
those indicated by such forward-looking statements are: (i) the assimilation of
acquisitions, (ii) the management of the Company's growth and expansion, (iii)
dependence on major customers, or on key personnel, (iv) development by
competitors of new or superior products or services, or entry into the market of
new competitors, (v) fluctuations in paper prices, (vi) integrity and
reliability of the Company's data, (vii) volatility of the Company's stock
price, (viii) changes in the business services outsourcing industry, (ix)
significance of intangible assets, (x) changes related to compensatory stock
options and (xi) other risks identified from time to time in the Company's
reports and registration statements filed with the Securities and Exchange
Commission.

OVERVIEW

     During the nine months ended September 30, 1999, the Company completed
several acquisitions which were accounted for as purchases, the most significant
of which were: M-R Group plc ("M-R"), Vetri Systems, Inc. and its affiliate
Vetri Software India, Ltd., Bonner & Moore Computing Company, a




                                       12


<PAGE>   14


division of Bonner & Moore Associates, Inc., the Texas division of Compex Legal
Services, MSI Digital Imaging Solutions, Inc., Cover-All Computer Holdings
Company and its affiliates, MSCI, Inc., Crest Information Technologies, Inc.,
Marketing Associates, Inc. and Addressing Services Company, Inc.

     In connection with the M-R merger, the Company recorded approximately $7.8
million of merger-related costs which were charged to operations during the
second quarter of 1999, related to leases, the consolidation of facilities,
severance and other related expenses for Lason facilities closed or consolidated
into M-R facilities.

     Although management anticipates that the Company will continue to acquire
complementary businesses in the future, there can be no assurance that the
Company will be able to identify and acquire attractive acquisition candidates,
profitably manage such acquired companies or successfully integrate such
acquired companies into the Company without substantial costs, delays or other
problems. In addition, there can be no assurance that any companies acquired in
the future will be profitable at the time of acquisition or will achieve sales
and profitability justifying the Company's investment therein or that the
Company will recognize the synergies expected from such acquisitions.

RESULTS OF OPERATIONS - THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED WITH
THREE MONTHS ENDED SEPTEMBER 30, 1998.

     Consolidated net revenues increased 91% to $148.9 million for the three
months ended September 30, 1999 from $77.9 million in the third quarter of 1998.
Approximately $60.7 million of the increase was due to acquisitions and
approximately $10.3 million was due to growth in the Company's existing
business. The majority of the internal growth came from an increase in image and
data capture revenues of approximately $10.7 million, largely the result of
successful cross-selling of the Company's core services and the Company's focus
on fast growing markets such as e-commerce.

     Gross profit increased to $57.2 million for the third quarter of 1999 from
$27.0 million for the comparable 1998 quarter primarily due to the increase in
net revenues. Gross profit as a percentage of net revenues was 38% for the three
months ended September 30, 1999 versus 35% for the comparable period of 1998.
M-R's margins were higher due to higher revenues at divisions with relatively
fixed costs (divisions providing software and digitization services).

     Selling, general and administrative expenses increased $18.9 million to
$34.5 million, or 23% of net revenues, for the three months ended September 30,
1999 from $15.6 million, or 20% of net revenue for the comparable 1998 quarter.
Approximately $14.0 million of the increase was due to selling, general and
administrative expenses of acquired companies. The remaining increase was
primarily due to higher compensation and other corporate overhead expenses
associated with managing a larger consolidated organization.

     Amortization of intangibles increased to $4.8 million for the three months
ended September 30, 1999 from $1.7 million for the third quarter of 1998
primarily due to an increase in goodwill related to the business acquisitions
completed.

     Net interest expense was $3.8 million for the 1999 third quarter compared
to $1.7 million in 1998. The increase is primarily due to higher average
borrowing balances resulting from borrowings used primarily to fund business
acquisitions.

     Provision for income taxes as a percentage of pre tax income increased to
42% for the third quarter of 1999 from 40% in the comparable 1998 quarter
primarily due to an increase in goodwill amortization expense which is not
deductible for federal income tax purposes.

<PAGE>   15


RESULTS OF OPERATIONS - NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED WITH NINE
MONTHS ENDED SEPTEMBER 30, 1998.

     Consolidated net revenues increased 100% to $374.4 million for the nine
months ended September 30, 1999 from $187.1 million for the comparable period of
1998. Approximately $154.7 million of the increase was due to acquisitions and
approximately $32.8 million was due to growth in the Company's existing
business. The internal growth was primarily the result of higher image and data
capture and data management revenue.

     Gross profit increased to $137.9 million for the nine months ended
September 30, 1999 from $65.9 million for the comparable 1998 period primarily
due to the increase in net revenues. Gross profit as a percentage of net
revenues was 37% and 35% for the nine months ended September 30, 1999 and 1998,
respectively.

     Selling, general and administrative expenses increased $46.7 million to
$84.8 million, or 23% of net revenues for the first nine months of 1999, from
$38.1 million, or 20% of net revenues in the same period of 1998. Approximately
$31.1 million of the increase was due to selling, general and administrative
expenses of acquired companies. The remaining increase was primarily due to
increased compensation and other corporate overhead expenses associated with
managing a larger consolidated organization.

     Amortization of intangibles increased to $10.6 million for the nine months
ended September 30, 1999 from $3.9 million for the comparable 1998 period
primarily due to an increase in goodwill related to business acquisitions
completed.

     The decline in operating income as a percentage of revenue from 13% in the
first nine months of 1998 to 9% in the corresponding period of 1999 is the
result of the merger-related charges of $7.8 million discussed in the overview
of this Item 2, offset by increased operating income from acquisitions and
internal growth.

     Net interest expense was $8.7 million for the first nine months of 1999
compared to $3.9 million in 1998. The increase is primarily due to higher
average borrowing balances resulting from borrowings used mainly to fund
business acquisitions.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has funded its operations and acquisitions through a
combination of cash flow from operations, bank borrowings and the issuance of
shares of common stock.

     Cash flows provided by operating activities totaled $9.0 million for the
nine months ended September 30, 1999 compared to $4.7 million usage for the
comparable period of 1998. The increase in operating cash flows in 1999 is
primarily due to an increase in net income before noncash merger-related
expenses and other non-cash charges such as depreciation and amortization,
partially offset by higher accounts receivable and other current assets.

         Cash flows used in investing activities totaled $156.2 million and
$131.3 million for the nine months ended September 30, 1999 and 1998,
respectively, and was primarily used to fund the acquisition of businesses and
invest in capital equipment and software development activities. Cash used for
acquisitions was approximately $127.9 million and $117.9 million for the nine
months ended September 30, 1999 and 1998, respectively. Cash used to invest in
capital equipment and software development activities totaled $29.1 million for
the 1999 first nine months, compared to $13.8 million for the


                                       14




<PAGE>   16

comparable period of 1998. During the first nine months of 1999 and 1998, the
Company invested approximately $5.7 and $3.4, respectively, for the development
and implementation of computer software primarily to support the Company's
domestic and international operations and information processing needs. These
projects and related costs will continue as the Company pursues its acquisition
strategy and its focus on high technology services such as e-commerce.

     Cash flows provided by financing activities totaled $156.2 million in 1999
compared to $135.1 million for the comparable period of 1998 and largely
consisted of borrowings on the Company's revolving line of credit and term loan
primarily used to fund the payments for acquired businesses and for working
capital requirements. In the 1998 period, the Company sold 2,925,000 shares of
its common stock for net proceeds of approximately $130.8 million, after
deducting underwriting discounts and other offering expenses. Additionally,
during the first quarter of 1999 and 1998 the Company repaid promissory notes in
the amount of $18.6 million and $6.2 million, respectively, relating to business
acquisitions in the fourth quarter of 1998 and 1997, respectively.

     Credit Agreement Borrowings

     During the quarter ended September 30, 1999, the Company amended and
restated its credit agreement with its lenders. The amended credit agreement has
a revolving credit facility of $150 million, which the Company may increase up
to $250 million, subject to certain limitations. A portion of the revolving
credit facility of up to $50 million is available to the Company for borrowings
in Euro, British pound sterling, Canadian dollars and other freely traded
currencies to be agreed upon with the lenders. The amendment to the credit
agreement also added a term loan facility of $150 million. The Company is
required to begin quarterly principal and interest payments on the term loan
commencing May 31, 2000, with final maturity on both loan portions in 2004.
Borrowings under the credit agreement will be used to finance additional
acquisitions of businesses, working capital, capital expenditures and other
corporate purposes. Borrowings under the credit agreement are secured by
guarantees of certain of the Company's subsidiaries, as well as pledges of the
capital stock of certain subsidiaries. Interest on amounts outstanding is
calculated based on interest rates determined at the time of borrowing.
Borrowings bear interest at rates ranging from a Eurodollar rate plus a maximum
of 2.00% (7.68% at November 10, 1999) or a base rate plus a maximum of 0.50%
(8.25 at November 10, 1999), at the Company's election at the time of borrowing.
The credit agreement contains restrictions on acquisitions, dispositions of
assets and the incurrence of other liabilities and contains certain financial
ratio covenants. As of November 10, 1999, $267.4 million was borrowed under the
credit agreement.

     Future Capital Needs

     The Company's liquidity and capital resources have been significantly
affected by acquisitions of businesses and, given the Company's acquisition
strategy, may be significantly affected for the foreseeable future. To date, the
Company has financed its acquisitions with borrowings under its credit
agreement, with shares of its common stock and with cash from operations.

     The Company's ability to obtain cash adequate to fund its needs depends
generally on the results of its operations and the availability of financing.
Management believes that cash flow from operations, in conjunction with
borrowings from its existing and any future credit agreements and possible
issuance of shares of its common stock, will be sufficient to meet debt service
requirements, make possible future acquisitions and fund capital expenditures in
the future. However, there can be no assurance in this regard or that the terms
available for any future financing, if required, would be favorable to the
Company.

YEAR 2000

     The Company uses a significant number of computer software programs and
operating systems in its internal operations. To the extent that these software
applications contain a source code that is unable to interpret appropriately the
upcoming calendar year 2000, some level of modification or even possible
replacement of such source code or program applications will be necessary. In
addition, the Company may experience significant adverse business interruptions
if significant customers and/or suppliers are not prepared for the year 2000.

     The Company has a standing committee consisting of key management personnel
to address the year 2000 issue. The Company has surveyed its customers and
suppliers identifying those that are most critical to the operations of the
Company. Meetings were scheduled between such entities and Company personnel to
gain a clear understanding of their year 2000 readiness and any potential impact
on the Company. Appropriate contingencies were developed based upon these
meetings.

     The Company is currently modifying its computer software programs and
operating systems to make each significant system and program "Year 2000
Compliant". Substantially all critical business systems are year 2000 compliant,
and most individual business-unit systems (including those of M-R) are currently
compliant. All final audits and certifications will be completed by the end of
November 1999. The 10 largest site audits were performed by an independent
agency. As of September 30, 1999, the Company has incurred approximately $3.8
million in connection with its year 2000 compliance program and anticipates that
it will incur an additional estimated $0.5 to complete the program.

     The Company does not anticipate a material year 2000 business interruption
due to the nature of its operating systems, and the customers and suppliers with
which it transacts business. However, there can be no assurance that the Company
will not incur unanticipated costs or systems interruptions, which could have a
material adverse effect on the Company's business, financial condition or
results of operations. In addition, there can be no assurance that failure of
the Company's critical customers or suppliers to be year 2000 compliant will not
have a material adverse effect on the Company's business, financial condition or
results of operations. In addition, there can be no assurance that businesses
acquired in the future will not incur unanticipated costs or systems
interruption, which could have an adverse effect on the Company's business,
financial condition or results of operations.

INFLATION

     Certain of the Company's expenses, such as wages and benefits, occupancy
costs, and equipment repair and replacement, are subject to normal inflation.
Supplies, such as paper and related products, can be subject to significant
price fluctuations. Although the Company to date has been able to substantially
offset any such cost increases through increased operating efficiencies, there
can be no assurance that the Company will be able to offset any future cost
increases through similar efficiencies or increased charges for its products and
services.

LITIGATION

     The Company is, from time to time, a party to legal proceedings arising in
the normal course of its business. Management believes that none of the legal
proceedings currently outstanding will have a material adverse effect on the
Company's business, financial condition or results of operations.

ITEM 3. QUANTITIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Lason has exposure to interest rate risk on its obligations outstanding
under the existing credit agreement, which bear interest at a variable rate.
Based on the Company's outstanding balance under the credit agreement on
September 30, 1999, a one-percent increase or decrease in interest rates would
decrease or increase, respectively, the Company's pre tax earnings and operating
cash flows by approximately $2.4 million on an annualized basis.

plan, an additional 8,064 shares were issued in the third quarter of 1999 and
additional shares could be issued upon exercise of M-R options still
outstanding.
