    Basis of Consolidation

         The accompanying condensed consolidated financial statements include
the accounts of Renaissance Worldwide, Inc. and its wholly owned subsidiaries.
All intercompany balances and transactions have been eliminated.

    Interim Financial Statements

         The condensed consolidated balance sheet at September 25, 1999 and
condensed consolidated statements of operations and of cash flows for the nine
month periods ended September 26, 1998 and September 25, 1999 are unaudited and,
in the opinion of management, include all adjustments (consisting of normal and
recurring adjustments) necessary for a fair presentation of results for these
interim periods. Certain information and footnote disclosures normally included
in the Company's annual consolidated financial statements have been condensed or
omitted. The results of operations for the interim period ended September 25,
1999 are not necessarily indicative of the results to be expected for future
quarters or the entire year. The balance sheet at December 26, 1998 contained
herein has been derived from the audited consolidated financial statements at
that date but does not include all of the information and footnotes required by
generally accepted accounting principles for complete financial statements.
These interim condensed consolidated financial statements should be read in
conjunction with the audited consolidated financial statements for the year
ended December 26, 1998, which are contained in the Company's 1998 Report on
Form 10-K.

    Earnings Per Share

         Basic earnings per share has been computed by dividing net income by
the weighted average number of common shares outstanding. Diluted earnings per
share has been computed by dividing net income by the weighted average number of
common shares and dilutive potential common stock outstanding. Potential common
stock includes stock options and warrants, calculated using the treasury stock
method. A reconciliation of the weighted average number of common shares
outstanding is as follows:

    Translation of Foreign Currencies

         The functional currency for the Company's subsidiaries is the local
currency. Assets and liabilities are translated into U.S. dollars at exchange
rates in effect at the balance sheet date. Income and expense items and cash
flows are translated at average exchange rates for the period. Cumulative net
translation adjustments are included in stockholders' equity. Gains and losses
resulting from foreign currency transactions, not significant in amount, are
included in the results of operations as other income (expense).

    Other Comprehensive Income

         The Company accounts for comprehensive income in accordance with
Statement of Financial Accounting Standards No. 130, "Reporting of Comprehensive
Income." This Statement requires disclosure of comprehensive income and its
components in interim and annual reports. For the quarters ended September 26,
1998 and September 25, 1999, comprehensive income (expense) items included in
stockholders' equity consisted of translation adjustments of $(128) and $(1).
For the nine months ended September 26, 1998 and September 25, 1999,
comprehensive income (expense) items included in stockholders' equity consisted
of translation adjustments of $(55) and $(630).


2. Acquisition of Subsidiaries--Purchases

         In January 1999, the Company completed the acquisition of
Infosolutions.edu for approximately $5,200 including a $2,500 notes payable.
Infosolutions.edu is an addition to the Company's Enterprise Solutions Group and
specializes in providing services to universities and other non-profit
organizations.

         In connection with certain earnout agreements related to previous
acquisitions, the Company paid $9,500 in contingent consideration during the
nine months ended September 25, 1999, which was recorded as additional purchase
price.

3. Acquisition of Subsidiaries--Pooling of Interests

         In the second quarter of 1998, the Company, through a wholly owned
subsidiary, acquired all of the outstanding stock of Neoglyphics Media
Corporation ("Neoglyphics") and Triad Data, Inc. ("Triad"). In total, 4,554,759
shares of the Company's Common Stock were exchanged for all of the outstanding
common stock of Neoglyphics and Triad. In addition, outstanding stock options to
purchase Neoglyphics common stock were converted into options to purchase
119,940 shares of the Company's Common Stock. These transactions were accounted
for as pooling of interests and, therefore, the financial statements were
restated to include the financial condition, results of operations and cash
flows of these two companies for all periods presented. The Company incurred
$6,904 in acquisition-related expenses during the period related to these
transactions. These costs are disclosed as a separate line in the statement of
income for the period.


4. Long-Term Debt

         The Company's line of credit existing at December 26, 1998 was
terminated on March 24, 1999. In February of 1999, the Company entered into a
new line of credit ("Interim Facility") with a different bank to provide a
borrowing base of 85% of eligible accounts receivable as defined, up to a
maximum borrowing of $110,000. Interest was payable monthly in arrears at the
LIBOR rate plus 2.00% or the higher of the bank's prime rate or the Fed Funds
rate plus 0.50%, plus 0.75%, at the Company's option. The Interim Facility was
collateralized by all of the assets of the Company, contained certain
restrictions, and required maintenance of certain financial covenants. The
Interim Facility was a short-term facility to be used until syndication of a
senior term loan facility committed to by the bank. The Interim Facility was
used to repay the outstanding borrowings on the existing line of credit that was
terminated on March 24, 1999.

         On July 15, 1999 the Company entered into a three-year, $150,000
revolving credit and term loan agreement (the "Credit Facility") with a bank
syndicate. The Credit Facility consists of a revolving line of credit of
$100,000 ("Revolving Credit Facility") and a term loan of $50,000 ("Term Loan").
The Credit Facility bears interest at the higher of the Federal Funds Rate plus
0.50% or the prime rate, plus up to 1.75% or LIBOR plus up to 3.0%, depending on
the Company's level of compliance with certain financial ratios. The Credit
Facility requires the Company to make quarterly principal payments of $250 on
the Term Loan beginning September 15, 2000 and each quarter thereafter until
June 15, 2002. The remaining obligations under the Term loan would be repaid on
July 15, 2002 along with any outstanding borrowings under the Revolving Credit
Facility. The Credit Facility contains various covenants, including the
maintenance of defined financial ratios and is secured by all of the assets of
the Company and contains certain restrictions.

         On September 15, 1999, the Company announced that it was revising its
revenue and earnings estimates for the third and fourth quarters of 1999 due to
a softening in the demand for services in two of its core industry sectors -
Enterprise Solutions and IT Consulting Services. Based upon this revised
outlook, the Company informed the bank syndicate that it would not be in
compliance with certain of its financial covenants for the third quarter of
1999. On November 4, 1999, the Company and the banks signed an amendment to the
Credit Facility amending certain financial covenants for the third quarter of
1999 through the third quarter of 2000, reverting back to the original financial
covenants established in the Credit Facility thereafter. The Credit Facility, as
amended, now bears interest at the higher of the Federal Funds Rate plus 0.50%
or the prime rate, plus up to 2.25% or LIBOR plus up to 3.5%, depending on the
Company's level of compliance with certain financial ratios. In connection with
this amendment, the Company will be required to pay amendment fees to the banks
and related expenses of approximately $500 which was recorded in the third
quarter of 1999 as interest and other expense, net.

         As of September 25, 1999, the availability under the Credit Facility
was approximately $18,500. The weighted average interest rate on the Credit
Facility at September 25, 1999 was 8.39%.

5. Extraordinary Item and Writedown of Assets

        In May 1999, the Company sold certain assets related to the Enterprise
Solutions group for $10,000 in cash and $2,000 in notes receivable. In
connection with this sale, the Company recognized an after tax gain of $833. The
gain on sale has been classified as an extraordinary item because the pooling of
interests method of accounting was applied to the original acquisition of these
assets within the last two years. The Company also recorded a $2,950 charge
associated with this sale which has been classified as a writedown of assets
within income from operations. This charge relates to other assets, not related
to prior pooling of interests transaction, disposed of in the sale of this
business.


6. Segment Reporting

         The Company adopted SFAS 131 in fiscal 1998. The Company's four primary
business segments include: Business Strategy, Enterprise Solutions, Government
Solutions and IT Consulting Services. The following presents information about
reported segments for the three and nine months ended September 26, 1998 and
September 25, 1999. Certain amounts previously reported have been reclassified
to conform to the Company's current basis of presentation.

Item II: Management's Discussion and Analysis of Financial Condition
         and Results of Operations

         On September 15, 1999 the Company announced that it expected revenue
and earnings per share for the third quarter ending September 25, 1999 to be
below published estimates of security analysts. The Company attributes the
expected shortfalls in revenue and earnings to a softening in demand for
services in two of its core business units; Enterprise solutions and IT
Consulting Services. The Company also believes that the slowdown in demand for
enterprise resource planning ("ERP") and IT consulting and staffing services
will continue through the end of the year, and that's its revenue and earnings
for the fourth quarter would be similarly affected. The Company believes this
softening has resulted from its customers and potential customers curtailing
current projects or deferring new project development and spending to next year
because of concerns about the impact of the Year 2000 (Y2K) issue. The Company
believes that this Y2K issue has created a significant slowdown in the industry
and a hesitation in the marketplace as clients shift their staffing and spending
priorities away from initiating new IT projects.

RESULTS OF OPERATION:

Three months ended September 26, 1998 and September 25, 1999

         Revenue. Total revenue decreased 9.4% to $189,409 for the third quarter
of fiscal 1999 from $209,073 in the third quarter of 1998. This revenue decrease
was attributable to a 33.7% decrease in Enterprise Solutions revenue which
decreased to $40,439 for the third quarter of 1999 from $61,025 for the
corresponding period of 1998 and a 28.3% decrease in Business Strategy revenue
which decrease to $8,510 for the third quarter of 1999 from $11,868 for the
corresponding period of 1998. These decreases were partially offset by a 69%
increase in Government Solutions revenue which increased to $9,248 in the third
quarter of 1999 from $5,472 for the corresponding period of 1998 while IT
Consulting Services revenue increased only 0.4% to $131,212 from $130,708 for
the corresponding period of 1998. The Company believes that the overall decrease
in Enterprise Solutions and IT Consulting Services revenue can be attributed to
the previously mentioned Y2K issues mentioned above. In addition, Enterprise
Solutions was impacted by the disposition of Neoglyphics Media business in the
second quarter of 1999. Business Strategy experienced a decrease in revenue
primarily due to the disposition of the COBA UK and Technomics subsidiaries
during the first quarter of 1999.

         Gross Profit. Gross profit decreased 18.5% to $58,173 for the third
quarter of 1999 from $71,392 for the comparable prior period. As a percentage of
revenue, gross profit decreased to 30.7% for the period compared to 34.1% for
the comparable prior period. The decrease in gross profit percentage was
attributable primarily to a shift in the mix of the Company's business as the
percentage of revenue derived from the higher margin Business Strategy,
Enterprise Solutions and Government Solutions Groups decreased in relation to
the lower margin IT Consulting Services for the third quarter of 1999.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased by 5.1% to $53,930 for the third quarter of
1999 from $51,297 for the comparable prior period. As a percentage of revenue,
selling, general and administrative expenses increased to 28.5% from 24.5% for
the comparable prior period. This increase was attributable primarily to
investments in the Company's information technology, corporate finance and
administrative functions and telecommunications and facilities infrastructure to
accommodate the growth of the past year.

        Restructuring Charges and Asset Writedowns. Restructuring charges and
asset writedowns of $8,980 in the third quarter of 1998 were incurred in
connection with the implementation of a restructuring plan designed to eliminate
redundant facilities and processes. The charges included $3,528 to writedown
non-performing assets, $1,254 for ongoing lease payments in excess of estimated
sublease income for facilities vacated and employee severance and other payments
of $4,198 related to the restructuring.

         Interest and Other Expense, Net. Interest and other expense, net,
increased to $2,308 for the third quarter of fiscal 1999 from $1,811 in expense
for the comparable prior period. This increase was primarily associated with
bank amendment fees and related expenses incurred in connection with the
amendment of the Company's financial covenants under its Credit Facility (see
Note 4 -Long-Term Debt).

Nine months ended September 26, 1998 and September 25, 1999

         Revenue. Total revenue increased 4.7% to $608,166 for the first nine
months of fiscal 1999 from $580,904 in the first nine months of 1998. These
increase was attributable to a 98.2% increase in Government Solutions revenue
which increased to $26,827 in the first nine months of 1999 from $13,525 for the
corresponding period of 1998 while IT Consulting Services revenue increased
10.6% to $414,830 from $374,937 for the corresponding period of 1998. These
revenue increases were partially offset by a 11.0% decrease in Enterprise
Solutions revenue which decreased to $139,438 for the first nine months of 1999
from $156,677 for the corresponding period of 1998 and a 24.3% decrease in
Business Strategy revenue which decreased to $27,071 for the first nine months
of 1999 from $35,755 for the corresponding period of 1998. The Company believes
that the overall decrease in Enterprise Solutions and the slow down in the IT
Consulting Services revenue can be attributed to the previously mentioned Y2K
issues. In addition, Enterprise Solutions was impacted by the disposition of
Neoglyphics Media business in the second quarter of 1999. Business Strategy
experienced a decrease in revenue primarily due to the disposition of the COBA
UK and Technomics subsidiaries during the first quarter of 1999.

         Gross Profit. Gross profit decreased 4.9% to $187,033 for the third
quarter of 1999 from $196,762 for the comparable prior period. As a percentage
of revenue, gross profit decreased to 30.8% for the period compared to 33.9% for
the corresponding period of 1998. The decrease in gross profit percentage was
attributable primarily to a shift in the mix of the Company's business as the
percentage of revenue derived from the higher margin Business Strategy,
Enterprise Solutions and Government Solutions Groups decreased in relation to
the lower margin IT Consulting Services for the third quarter of 1999.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased by 12.4% to $166,333 for first nine months of
fiscal 1999 from $147,959 in the corresponding period of 1998. As a percentage
of revenue, selling, general and administrative expenses increased to 27.4% from
25.5% for the comparable prior period. This increase was attributable primarily
to investments in the Company's information technology, corporate finance and
administrative functions and telecommunications and facilities infrastructure to
accommodate the growth of the past year.

        Restructuring Charges and Asset Writedowns. The Company recorded asset
writedowns of $2,950 for the second quarter of fiscal 1999 which were incurred
in connection with the sale of assets during the quarter. Assets written down
were not related to prior pooling of interests transactions. Restructuring
charges and asset writedowns of $8,980 in the third quarter of 1998 were
incurred in connection with the implementation of a restructuring plan designed
to eliminate redundant facilities and processes. The charge included $3,528 to
writedown non-performing assets, $1,254 for ongoing lease payments in excess of
estimated sublease income for facilities vacated and employee severance and
other payments of $4,198 related to the restructuring.

        Acquisition Related Expenses. Acquisition related expenses of $6,904 for
the first nine months of fiscal 1998 were incurred in connection with the
Neoglyphics and Triad acquisitions.

         Interest and Other Expense, Net. Interest and other expense, net,
increased to $6,573 for the first nine months of fiscal 1999 from $3,743 in
expense for the comparable prior period. This change was a result of increased
balances under the Company's credit facilities due to payments for acquisitions
made in 1998, other contingent payments made for acquisitions, fixed asset
expenditures as well as increased working capital needs and bank amendment fees
and related expenses incurred in connection with the amendment of the Company's
financial covenants under its Credit Facility (See Note 4 - Long-Term Debt).

         Extraordinary gain. The extraordinary gain recognized during the second
quarter of 1999 related to the sale of certain assets related to the Enterprise
Solutions Group for $10,000 in cash and $2,000 in notes receivable. In
connection with this sale, the Company recognized an after tax gain of $833. The
gain on sale has been classified as an extraordinary item because the pooling of
interests method of accounting was applied to the original acquisition of these
assets within the last two years.

Liquidity and Capital Resources

         The Company's line of credit existing at December 26, 1998 was
terminated on March 24, 1999. In February of 1999, the Company entered into a
new line of credit ("Interim Facility") with a different bank to provide a
borrowing base of 85% of eligible accounts receivable as defined, up to a
maximum borrowing of $110,000. Interest was payable monthly in arrears at the
LIBOR rate plus 2.00% or the higher of the bank's prime rate or the Fed Funds
rate plus 0.50%, plus 0.75%, at the Company's option. The Interim Facility was
collateralized by all of the assets of the Company, contained certain
restrictions, and required maintenance of certain financial covenants. The
Interim Facility was a short-term facility to be used until syndication of a
senior term loan facility committed to by the bank. The Interim Facility was
used to repay the outstanding borrowings on the existing line of credit that was
terminated on March 24, 1999.

         On July 15, 1999 the Company entered into a three-year, $150,000
revolving credit and term loan agreement (the "Credit Facility") with a bank
syndicate. The Credit Facility consists of a revolving line of credit of
$100,000 ("Revolving Credit Facility") and a term loan of $50,000 ("Term Loan").
The Credit Facility bears interest at the higher of the Federal Funds Rate plus
0.50% or the prime rate, plus up to 1.75% or LIBOR plus up to 3.0%, depending on
the Company's level of compliance with certain financial ratios. The Credit
Facility requires the Company to make quarterly principal payments of $250 on
the Term Loan beginning September 15, 2000 and each quarter thereafter until
June 15, 2002. The remaining obligations under the Term loan would be repaid on
July 15, 2002 along with any outstanding borrowings under the Revolving Credit
Facility. The Credit Facility contains various covenants, including the
maintenance of defined financial ratios and is secured by all of the assets of
the Company and contains certain restrictions.

         On September 15, 1999, the Company announced that it was revising its
revenue and earnings estimates for the third and fourth quarters of 1999 due to
a softening in the demand for services in two of its core industry sectors -
Enterprise Solutions and IT Consulting Services. Based upon this revised
outlook, the Company informed the bank syndicate that it would not be in
compliance with certain of its financial covenants for the third quarter of
1999. On November 4, 1999, the Company and the banks signed an amendment to the
Credit Facility amending certain financial covenants for the third quarter of
1999 through the third quarter of 2000, reverting back to the original financial
covenants established in the Credit Facility thereafter. The Credit Facility, as
amended, now bears interest at the higher of the Federal Funds Rate plus 0.50%
or the prime rate, plus up to 2.25% or LIBOR plus up to 3.5%, depending on the
Company's level of compliance with certain financial ratios. In connection with
this amendment, the Company will be required to pay amendment fees to the banks
and related expenses of approximately $500 which was recorded in the third
quarter of 1999 as interest and other expense, net.

         As of September 25, 1999, the availability under the Credit Facility
was approximately $18,500. The weighted average interest rate on the Credit
Facility at September 25, 1999 was 8.39%.

         The Company had cash flows from operations of $36,047 for the nine
months ended September 25, 1999. The operating cash flows were due primarily to
a $17,567 decrease in other current assets and other assets primarily attributed
to a reduction in prepaid expenses, security deposits on facilities and the
refund on income taxes offset partially by an increase in accounts receivable of
$5,084.

         The Company used cash of $18,997 for investing activities for the nine
months ended September 25, 1999. The Company used $12,149 of cash for
acquisitions, of which approximately $9,500 was for certain earnout agreements
related to previous acquisitions which was recorded as additional purchase
price, and $15,420 for fixed asset purchases during the period. This use of
funds was partially offset by $10,000 of cash received from the sales of certain
assets in the Enterprise Solutions Group.

         The Company used $13,424 of cash for financing activities for the nine
months ended September 25, 1999. This use of cash was attributable primarily to
repayments on the Company's credit facilities, net of the establishment of the
Term Loan portion under the new Credit Facility.

                           RENAISSANCE WORLDWIDE, INC.


              The Company anticipates that its primary uses of working capital
in future periods will be for funding growth, either through acquisitions, the
internal development of existing branch offices or the development of new branch
offices and new service offerings. The Company also anticipates making
approximately $18,000 in capital expenditures in the next twelve months
principally to upgrade its computer systems and facilities. In connection with
certain of its acquisitions, the Company may be obligated to make certain
contingent payments during the next several years, including approximately
$9,000 which the Company is currently required to pay over the next 12 months.
The Company does not believe that such payments will have a material impact on
the Company's liquidity, results of operations or capital requirements. The
Company's principal capital requirement is working capital to support the
accounts receivable associated with its revenue growth. The Company believes
that its new Credit Facility, together with cash flows from operations, will be
sufficient to meet the Company's presently anticipated working capital and
financing needs for at least the next 12 months.

Year 2000

         Generally, the Company has completed an assessment of Year 2000 issues
with respect to its business systems and has already begun to take actions to
ensure their compliance. Plans and associated milestones are being executed to
ensure that those business systems not currently certified as compliant are
either upgraded to certified status or replaced well in advance of December 31,
1999. Based on the completed assessment, management does not expect that the
costs of bringing the Company's systems into compliance with Year 2000 to have a
material adverse effect on the Company's financial position, results of
operations or liquidity. The Company does not believe that it is subject to
significant business risks related to its customers' and suppliers' Year 2000
efforts.

         The Company does not currently have contingency plans with respect to
the Year 2000 problem. Should any Year 2000 issues be identified in the current
months which the Company believes could remain unresolved at year end, the
Company will develop contingency plans. Consultants' internal work for the
Company could negatively impact the Company's ability to employ its consultants
on billable projects which could have a material adverse effect on the Company's
results of operations, financial position or cash flow.

Item III.  Quantitative and Qualitative Disclosures About Market Risk

         The Company is exposed to a variety of risks, including foreign
currency fluctuations and changes in interest rates on its borrowings. The
Company does not engage in trading market risk sensitive instruments for
speculative purposes. There have been no material changes in market risk
exposures from the information disclosed in the Form 10-K for the year ended
December 26, 1998.

Certain Factors That May Affect Future Operating Results

         The foregoing forward-looking statements involve risks and
uncertainties. The Company's actual performance and results may differ
materially due to many important factors, including, but not limited to, the
Company's dependence on the availability of qualified IT consultants, its
ability to sustain and manage growth, the risks associated with acquisitions,
its dependence on key clients, risks associated with international operations,
its dependence on key personnel, the relatively short history of profitability,
the impact of the government regulation on immigration, fluctuations in
operating results due in part to the opening of new branch offices, general
economic conditions, employment liability risks, and the like. For additional
and more comprehensive discussion of the risks associated with ownership of
Common Stock of the Company, please see the Risk Factors section of the
Company's Report on Form 10-K. As a result of these and other factors, there can
be no assurance that the Company will not experience material fluctuations in
future operating results on a quarterly or annual basis.
