                                February 29, 2000

NOTE 1:  BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements have been prepared
without audit by Harding Lawson Associates Group, Inc. (the "Company") in
accordance with generally accepted accounting principles for interim financial
statements and pursuant to the rules of the Securities and Exchange Commission
for Form 10-Q. Certain information and footnotes required by generally accepted
accounting principles for complete financial statements have been omitted. It is
the opinion of management that all adjustments considered necessary for a fair
presentation have been included, and that all such adjustments are of a normal
and recurring nature. For further information, refer to the audited financial
statements and footnotes included in the Company's Annual Report on Form 10-K
for the fiscal year ended May 31, 1999. Reclassification of certain balances
from the prior fiscal year have been made to conform to the February 29, 2000
presentation.

NOTE 2:  COMMITMENTS AND CONTINGENCIES

The Company is currently subject to certain claims and lawsuits arising in the
ordinary course of its business. In the opinion of management, adequate
provision has been made for all known liabilities that are currently expected to
result from these claims and lawsuits, and in the aggregate such claims are not
expected to have a material effect on the financial position of the Company. The
estimates used in establishing these provisions could differ from actual
results. Should these estimates change significantly, the effect on operations
for any quarterly or annual reporting period could be material.

NOTE 4:  RESTRUCTURING CHARGES

During May, 1999, the Company recorded charges of $4,383,000 for i) anticipated
losses associated with the planned disposal of its investments in its Australian
and Mexican operations; such investments were written down to their anticipated
net realizable value ($2,154,000), ii) severance and other costs associated with
the corporate reorganization and corporate office relocation ($2,029,000), and
iii) the writedown of goodwill associated with the Company's acquisition of EEC
Environmental, Inc. in 1993 ($200,000). As of February 29, 2000 and May 31,
1999, the accompanying consolidated financial statements reflect $0 and
$2,768,000 in accrued expenses, respectively, in connection with the
restructuring charges. The Company now considers the restructuring complete and
expects to incur no further charges.

Third Quarter Comparison for Fiscal Years 2000 and 1999

Net revenue for the fiscal quarter ended February 29, 2000 totaled $25,731, a
decrease of 2.1% from net revenue of $26,295 for the comparable quarter in the
prior fiscal year. The decrease in net revenue for the quarter ended February
29, 2000 was attributable to a decrease of $1,811 or 13% in net revenue from
domestic industrial clients and a decrease of $911 or 100% in net revenue from
international operations, primarily due to the sale of the Australian operations
during the second quarter of fiscal 2000. Net revenue was favorably impacted by
an increase of $1,520 or 30% in net revenue from state and local government
contracts and an increase of $638 or 11% in net revenue from federal government
contracts. Net revenue from domestic industrial clients accounted for 49% of
total net revenue for the current fiscal quarter compared to 55% for the prior
fiscal quarter. Net revenue from federal government contracts accounted for 25%
of total net revenue for the current fiscal quarter compared to 23% in the prior
fiscal quarter. Net revenue from state and local government contracts was 26% of
total net revenue for the


                                       8
<PAGE>

current fiscal quarter compared to 19% for the prior fiscal quarter. Net revenue
from international operations was 0% of total net revenue for the current fiscal
quarter compared to 3% in the prior fiscal quarter. Net revenue was unfavorably
impacted during the third quarter of fiscal 2000 by the Company obtaining a
lower rate per hour for services provided compared to the prior year due to the
competitive environment of the industry.

A portion of the services provided by the Company to its public sector clients
are performed under a relatively small number of larger contracts compared to
private sector clients. If the Company is unsuccessful in realizing the full
potential of these contracts or winning new contracts, or if funding delays are
experienced on previously awarded federal contracts, a material decline in
revenue could result.

Operating income for the third quarter of fiscal 2000 was $2,019, an increase of
265.1% from $553 for the same period in fiscal 1999. Operating margin increased
to 8.2% of net revenue in the current quarter compared to 2.6% in the third
quarter of fiscal 1999. The increase in operating income resulted from the
favorable impact of the Company's restructuring which has resulted in reduced
operating costs. The decrease in general expenses is due to reductions in
administrative personnel, cost containment and lower rent and related office
expenses due to office consolidations. The effective tax rate was 41% for the
third quarter of fiscal 2000 and was 42% in the third quarter of the prior year.

Net income for the quarter was $1,231 compared with $414 in the third quarter of
fiscal 1999, an increase of 197.3%. Basic earnings per share were $0.25 on 5,004
basic weighted average shares outstanding compared to $0.09 per share on 4,815
basic weighted average shares outstanding in the same period last year. Diluted
earnings per share were $0.24 on 5,145 diluted weighted average shares
outstanding compared to $0.09 per share on 4,830 diluted weighted average shares
outstanding in the same period last year.

Nine Month Comparison for Fiscal Years 2000 and 1999

Net revenue for the nine months ended February 29, 2000 was $83,782, an increase
of 3.7% from net revenue of $80,773 for the nine months ended February 28, 1999.
The increase in net revenue during fiscal 2000 was attributable to an increase
of $6,334 or 45% in net revenue from state and local government contracts
reduced by a) $1,703 or a 4% decrease in net revenue from domestic industrial
clients, b) $1,286 or a 42% decrease in net revenue from international
operations, primarily due to the sale of the Australian operations during the
second quarter of fiscal year 2000, and c) $336 or a 2% decrease in net revenue
from federal contracts. Net revenue from domestic industrial clients accounted
for 49% of total net revenue for the current fiscal year compared to 53% for the
prior fiscal year. Net revenue from federal government contracts accounted for
25% of total net revenue for the current fiscal year compared to 26% in the
prior fiscal year. Net revenue from state and local government contracts was 24%
of total net revenue for the current fiscal quarter compared to 17% for the
prior fiscal quarter. Net revenue from international operations was 2% of total
net revenue for the current fiscal year compared to 4% in the prior fiscal
quarter. During the first nine months of fiscal 2000, the Company also generated
more chargeable hours than in the prior year but at a lower rate per hour for
services provided, resulting in a net positive impact on revenues.

Operating income was $6,532, an increase of 181.7% from operating income of
$2,319 for the first nine months of the prior year. The operating margin
increased to 7.8% from 2.9% a year ago. The increase in operating income was due
to increased sales volume and the Company's restructuring which has resulted in
reduced operating expenses. The decrease in general expenses is due to
reductions in administrative personnel, cost containment and lower rent and
related office expenses due to office consolidations. In addition, during the
second quarter of the prior fiscal year, approximately $700 in charges were
incurred for severance and recruiting expenses associated with the Company's
change in its chief executive officer and costs associated with certain office
closures and abandoned office space.

The effective tax rate was 42% for the nine months ended February 29, 2000 and
February 28, 1999.


                                       9
<PAGE>

Net income for the nine months was $3,950, a 152.2% increase from net income of
$1,566 for the nine month period in the prior year. Basic earnings per share
were $0.79 on 4,984 weighted average basic shares outstanding compared to $0.32
on 4,844 weighted average basic shares outstanding in the same nine month period
of the prior year. Diluted earnings per share were $0.77 on 5,150 weighted
average diluted shares outstanding compared to $0.32 per share on 4,890 weighted
average diluted shares outstanding in the same period last year.

Liquidity and Capital Resources

For the nine months ended February 29, 2000, net cash provided by operations was
$417 compared to $2,344 for the same period last year. The decrease in cash
provided by operations was due primarily to $11,901 of increased payments of the
Company's payables and accrued liabilities, including those related to the
Company's restructuring costs, net of $8,381 from improved collections of the
Company's receivables and recovery of other current assets.

The Company made net capital expenditures of $1,779 in the first nine months of
fiscal 2000 compared to capital expenditures of $1,460 in the same period for
the prior year. The Company anticipates that its capital expenditures for the
current fiscal year will be slightly higher than those incurred in the prior
fiscal year.

On March 7, 1996 the Board of Directors of the Company approved a Common Stock
Repurchase Program ("1996 Program") that authorized the Company to purchase up
to a maximum of 500,000 shares of stock on the open market for the purpose of
funding the Company's various employee stock programs. The Company repurchased
310,000 shares during the first nine months of fiscal 1999 at an average price
of $8.72. No shares were repurchased during the same period of fiscal 2000.
There are 4,500 shares that remain available to be repurchased under the 1996
Program. On September 25, 1998, the Board authorized management to repurchase up
to 500,000 shares over four years.

The Company is a consulting engineering services firm engaged in providing
environmental, infrastructure, geotechnical and construction related services,
and encounters potential liability including claims for errors and omissions
resulting from construction defects, construction cost overruns, environmental
or other damage in the normal course of business. The Company is party to
lawsuits and is aware of potential exposure related to certain claims. In the
opinion of management, adequate provision has been made for all known
liabilities that are currently expected to result from these matters, and in the
aggregate, such claims are not expected to have a material impact on the
financial position and liquidity of the Company. The Company maintains a
consultant's environmental liability insurance policy as well as a general
liability insurance policy through an unrelated, rated carrier.

At February 29, 2000, the Company had cash on hand and cash equivalents of
$17,100. The Company has a $20 million revolving credit line agreement that
expires in November, 2000. At February 29, 2000 and February 28, 1999, the
Company had no borrowings outstanding under its line of credit. Borrowings were
available to the Company at an interest rate of 7.4% at February 29, 2000. The
Company believes it is in compliance with all covenants pertaining to the credit
line agreement.

The Company believes that its available cash and cash equivalents, as well as
cash generated from operations and its available credit line, will be sufficient
to meet the Company's cash requirements for the balance of the fiscal year.

Year 2000 Compliance

At this time the Company has not identified any significant problems associated
with the risks of Year 2000 compliance. The Company will continue to monitor its
information application and its hardware and software systems, as well as
vendors and suppliers' systems, for compliance.
