              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


Note 1.         BASIS OF PRESENTATION

         The accompanying financial statements of Nextera Enterprises, Inc.
("Nextera" or the "Company") have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments (consisting of normal recurring adjustments)
considered necessary for a fair presentation have been included. Operating
results for the three-month period ended March 31, 2000 are not necessarily
indicative of the results that may be expected for the year ended December 31,
2000.

         The consolidated balance sheet as of December 31, 1999 has been derived
from the 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 financial statements should be read in conjunction with the
financial statements and notes thereto, together with management's discussion
and analysis of financial condition and results of operations, contained in the
Company's Annual Report on Form 10-K filed by the Company with the Securities
and Exchange Commission on March 30, 2000.

ACQUISITIONS

         The Company has used the purchase method of accounting for all
acquisitions. Operating results of acquired companies have been included in the
Company's results of operations only from the date of each respective
acquisition. Allocation of purchase price for these acquisitions was based upon
estimates of the fair value of the net assets acquired and is subject to
adjustments based upon finalization of the purchase price allocation and post
closing adjustments. The Company does not expect that the aggregate purchase
price allocation or post-closing adjustments will be material.

2000

         Effective January 1, 2000, the Company acquired substantially all of
the assets and certain liabilities of Cambridge Economics, Inc. ("Cambridge
Economics"), a Massachusetts-based consulting firm that provides strategic,

million of cash and a $2.1 million promissory note payable June 30, 2002,
subject to post-closing adjustments.

         Effective September 30, 1999, the Company, through Sibson AP, LLC, a
newly formed acquisition subsidiary of the Company, acquired substantially all
of the assets of SCCAP Pty Limited ("SCCAP"). SCCAP, an Australian human
resources consulting firm, was acquired for $1.7 million in cash.

performance criteria for ERG.

acquisition.

         Effective January 29, 1999, the Company acquired The Alexander
Corporation Limited ("Alexander"), a United Kingdom-based human resources

Note 2.         EARNINGS (LOSS) PER SHARE

         Basic net income (loss) per share ("Basic EPS") is computed by dividing
net income by the weighted average number of common shares outstanding. Diluted
net income (loss) per common share ("Diluted EPS") is computed by dividing net
income by the weighted average number of common shares and dilutive common share
equivalents then outstanding.

         Basic and diluted earnings (loss) per share were calculated as follows:

Item 2.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    The disclosure and analysis in this quarterly report contain
"forward-looking statements." Forward-looking statements give our current
expectations or forecasts of future events. These statements can be identified
by the fact that they do not relate strictly to historic or current facts. They
use words such as "anticipate," "estimate," "foresee," "should," "expect,"
"project," "intend," "plan," "believe," and other words and terms of similar
meaning in connection with any discussion of future operating or financial
performance. In particular, these forward-looking statements include statements
relating to future actions or the outcome of financial results. From time to
time, we also may provide oral or written forward-looking statements in other
materials released to the public. Any or all of the forward-looking statements
in this report and in any other public statements may turn out to be incorrect.
They can be affected by inaccurate assumptions or by known or unknown risks and
uncertainties. Consequently, no forward-looking statement can be guaranteed.
Actual results may vary materially.

         Forward-looking statements are based on many factors that may be
outside our control, causing actual results to differ materially from those
suggested. These factors include, but are not limited to, those disclosed in the
Company's filings with the Securities and Exchange Commission, which include
risks associated with: our limited combined operating history; our history of
losses and the possibility that we may not be able to sustain or increase recent
profitability; uncertainties concerning the growth rate for commerce on the
Internet; our ability to attract and retain skilled consultants; our ability to
successfully integrate recent acquisitions; and voting control held by a single
large stockholder whose interests may be different than those of other
stockholders. New factors emerge from time to time, and it is not possible for
us to predict all these factors nor can we assess the impact of these factors on
our business or the extent to which any factor or combination of factors may
cause actual results to differ materially from those contained in any
forward-looking statements. Given these risks and uncertainties, you should not
place undue reliance on forward-looking statements as a prediction of actual
results.

COMPARISON OF THREE MONTHS ENDED MARCH 31, 2000 AND THREE MONTHS ENDED
MARCH 31, 1999

         Net Revenues. Net revenues increased 30% to $47.0 million for the three
months ended March 31, 2000 from $36.1 million for the three months ended March
31, 1999. This increase was primarily attributable to an increase in e-commerce
and e-business revenues and to the inclusion of revenues generated by ERG, which
was acquired effective June 1, 1999, SCCAP, which was acquired September 30,
1999 and Cambridge Economics, which was acquired January 1, 2000.

         Gross Profit. Gross profit increased 32.7% to $20.7 million for the
three months ended March 31, 2000 from $15.6 million for the three months ended
March 31, 1999. Gross margin as a percentage of sales increased to 44.2% for the
three months ended March 31, 2000 from 43.3% for the three months ended March
31, 1999. The increase in gross margin was due primarily to the acquisitions of
ERG and Cambridge Economics.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 31.8% to $13.4 million for the three months


                                      -8-

ended March 31, 2000 from $10.2 million for the three months ended March 31,
1999. As a percentage of revenues, such expenses increased slightly to 28.5% for
the three months ended March 31, 2000 from 28.1% for the three months ended
March 31, 1999.

         Interest Expense, Net. Interest expense, net decreased to $1.7 million
for the three months ended March 31, 2000 from $3.8 million for the three months
ended March 31, 1999. This decrease was due primarily to the repayment of a
portion of the Company's outstanding indebtedness with the proceeds from the
Company's initial public offering of Class A Common Stock, which was completed
in May 1999.

         Special Charges. In March 1999, the Company granted to certain
non-employee consultants of Lexecon fully-vested options to purchase 445,245
shares of Class A Common Stock at an exercise price of $14.00 per share. The
Company recorded a non-cash compensation charge of $4.4 million related to the
grant of these options in the three months ended March 31, 1999.

         Income tax expense. Income tax expense of $1.8 million, or 42.3% of
pretax income, was recorded for the three months ended March 31, 2000. The
provision varies from the statutory rate primarily due state income taxes and
the unfavorable impact of nondeductible goodwill amortization. No tax benefit
was recorded during the three months ended March 31, 1999 due to the Company's
inception to date lack of cumulative profitability.

LIQUIDITY AND CAPITAL RESOURCES

         Consolidated working capital was $43.9 million on March 31, 2000,
compared with $33.0 million on December 31, 1999. Included in working capital
were cash and cash equivalents of $4.3 million and $7.0 million on March 31,
2000 and December 31, 1999, respectively.

         Net cash used in operating activities was $11.7 million for the three
months ended March 31, 2000. The primary components of net cash used in
operating activities were an increase in accounts receivables of $16.4 million,
offset in part by net income of $2.5 million and depreciation and amortization
expense of $2.4 million.

         Net cash used in investing activities was $10.4 million for the three
months ended March 31, 2000. The primary components of cash used in investing
activities were the acquisition of Cambridge Economics in January 2000, totaling
$8.2 million, net of cash acquired, expenditures of $1.8 million for furniture,
equipment and leasehold improvements and other investments of $0.4 million.

         Net cash provided by financing activities was $19.5 million for the
three months ended March 31, 2000. The primary components of cash generated from
financing activities were borrowings under notes payables to banks totaled $20.0
million, of which $8.4 million was incurred in connection with acquisitions
completed during the three months ended March 31, 2000.

         Effective December 30, 1999, the Company entered into a Senior Credit
Facility which matures on March 29, 2002 and, as currently allocated, provides
for a $25 million revolving credit arrangement, intended for general corporate
purposes, and a $30 million revolving acquisition facility. The Senior Credit
Facility contains covenants, with which the Company was in compliance as of
March 31, 2000, related to the maintenance of financial


                                      -9-

ratios, operating restrictions and restrictions on the payment of dividends and
disposition of assets. As of March 31, 2000, total borrowings outstanding under
the Senior Credit Facility were $42,926,000. The Company believes that the
available capacity under the credit facility will be sufficient to meet its
operating and capital requirements for the next twelve months. However, there
can be no assurances that the Company's actual cash needs will not exceed
anticipated levels, that the Company will generate sufficient operating cash
flows to fund its operations in the absence of other sources or that acquisition
opportunities will not arise that require resources in excess of those currently
available.

IMPACT OF YEAR 2000

         Although the date is now past January 1, 2000 and the Company has not
experienced immediate adverse impact from the transition to the Year 2000, we do
not know whether we, our customers or our vendors have been affected in a manner
that is not yet apparent. We will continue to monitor our Year 2000 compliance
and the Year 2000 compliance of our customers and vendors. Due to the general
uncertainty inherent in the Year 2000 problem, especially the uncertainty
regarding the Year 2000 compliance of our customers and vendors, we are unable
to determine at this time whether the Year 2000 problem will have a material
adverse effect on our business, results of operations and financial condition.

         To date we have spent immaterial amounts to comply with accounting and
statutory requirements regarding the Year 2000. We believe that we will spend
minimal additional amounts for Year 2000 issues in the foreseeable future. These
assessments have not been independently verified. If we discover Year 2000
errors or defects in our internal systems, we may have to spend substantial
amounts in making repairs.

Item 3.  Quantitative and Qualitative Disclosures About Market Risks

         Interest Rate Risk

         We are exposed to changes in interest rates primarily from our senior
credit facility. We do not currently use interest rate derivative instruments to
manage exposure to interest rate changes. A hypothetical 100 basis point adverse
move in interest rates along the interest rate yield curve would not have a
material adverse effect on interest sensitive financial instruments at March 31,
2000.

         Foreign Currency Risk

         Currently, the majority of our sales and expenses are denominated in
U.S. dollars and as a result we have not experienced significant foreign
exchange gains and losses to date. While we are conducting some transactions in
foreign currencies during 2000, we do not anticipate that foreign exchange gains
or losses will be significant. We have not engaged in foreign currency hedging
activities to date.
