                   Notes to Consolidated Financial Statements
                                   (Unaudited)


1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited interim consolidated financial statements have been
prepared by management in accordance with the accounting policies described in
the Company's annual report for the year ended September 30, 1999. The
consolidated financial statements include the accounts of the Company and its
subsidiaries. All significant intercompany balances and transactions have been
eliminated in consolidation. Certain information and note disclosures normally
included in consolidated financial statements prepared in accordance with
generally accepted accounting principles have been omitted. These condensed
consolidated financial statements should be read in conjunction with the audited
consolidated financial statements and related notes included in the Company's
Annual Report on Form 10-K for the year ended September 30, 1999.

The consolidated financial statements reflect all adjustments which are, in the
opinion of management, necessary to present fairly the financial position of
Analytical Surveys, Inc., and subsidiaries at December 31, 1999 and the results
of their operations and cash flows for the three months ended December 31, 1998
and 1999.

Investment securities consist of corporate equity securities that are classified
as available-for-sale. Available-for-sale securities are recorded at fair value.
Unrealized holding gains and losses, net of the related tax effect, on
available-for-sale securities are excluded from earnings and are reported as a
separate component of stockholders' equity until realized.



2.       LITIGATION

The Company has been named as a defendant in several putative securities class
actions alleging a misstatement or omission of material facts concerning the
Company's operations and financial results. Plaintiffs seek to represent
themselves and a class of all public investors who purchased or otherwise
acquired common stock of the Company and who suffered damages, and seek an award
of compensatory damages and attorneys' fees and costs.

Because this litigation is at an early stage, it is impossible to evaluate the
impact that the above actions, or any future, related actions, may have on the
Company. However, it is reasonably possible that an unfavorable outcome in the
present litigation, or in any related future actions, could have a material
adverse impact on the Company's financial condition or results of operations in
one or more future reporting periods. The Company intends to defend itself
vigorously in this litigation.

OVERVIEW

ASI, a leading provider of data conversion and digital mapping services to users
of customized geographic information systems, was founded in 1981. From 1981 to
1995, the Company experienced steady growth in revenues with periodic
fluctuations in financial results. In 1995, the Company embarked on a growth
strategy, which sought to consolidate the fragmented GIS services industry. The
Company's acquisitions during the period are summarized in the following table:

         Date        Company                    Location              Employees
         ----        -------                    --------              ---------

         12/95       Intelligraphics            Wisconsin             200

         7/96        Westinghouse Landmark      North Carolina        105

         7/97        MSE Corporation            Indiana               325

         6/98        Cartotech                  Texas                 270

The Company recognizes revenue using the percentage of completion method of
accounting on a cost-to-cost basis. For each contract, an estimate of total
production costs is determined; these estimates are reevaluated regularly.
Production costs consist of internal costs, primarily salaries and wages, and
external costs, primarily subcontractor costs. Internal and external production
costs may vary considerably among projects and during the course of completion
of each project. At each accounting period and for each of the Company's
contracts, the percentage of completion is based on production costs incurred to
date as a percentage of total estimated production costs. This percentage is
then multiplied by the contract's total value to calculate the sales revenue to
be recognized. The percentage of completion is effected by any factors which
influence either the estimate of future productivity or the production cost per
hour used to determine future costs.

The Company recognizes losses on contracts in the period such loss is
determined. From the beginning of fiscal 1995 through the end of the first three
months of fiscal 2000, the Company has recognized aggregate losses on contracts
of approximately $1.6 million. Over the same period, the Company recognized
sales of approximately $250 million. Sales and marketing expenses associated
with obtaining contracts are expensed as incurred.

Backlog increases when new contracts are signed and decreases as revenue is
recognized. As of December 31, 1999, backlog was $79.8 million as compared with
$91.3 million as of September 30, 1999.

The Company engages in research and development activities. The majority of
these activities occur as the Company develops software or designs a product for
a particular contract, so that the costs of such efforts are included as an
integral part of the Company's services. Such custom-designed software can often
be applied to projects for other customers. These amounts expended by the
Company are not included in research and development expenses, although the
Company retains ownership of such proprietary software or products. The Company,
through its Advanced Technology Division, also engages in research and
development activities independently of the Company's work on particular
customer projects. For the three months ended December 31, 1998 and 1999, the
Company expended $67,072 and $95,567, respectively on such independent research
and development activities in the Advanced Technology Division.

On December 30, 1999, the Company announced it had revised its previously
announced fiscal 1999 results. On January 27, 2000, the Company announced that
it was conducting a detailed review of its cost-of-completion assumptions
related to its contracts under the supervision of the Audit Committee of the
Board of Directors that might lead to a restatement of its financial results for
fiscal 1999. As a result of this comprehensive review, the Company discovered
certain accounting errors that required a downward adjustment of the revenues
recognized in



                                       7
<PAGE>   8


each of the four quarters of fiscal 1999. The errors related principally to the
exclusion of certain contract-related costs in the estimated costs to complete
on certain projects; the untimely recognition of additional anticipated costs to
complete; and the inaccurate assessment of future production efficiencies and
inefficiencies affecting estimated costs to complete. When the Company's
analysis indicated that the estimated costs to complete a specific project were
based on inaccurate information or assumptions, an estimate was made of the
impact on previously recognized revenues as well as timing of the error, and the
appropriate fiscal 1999 quarter's operating results were restated accordingly.

THREE MONTHS ENDED DECEMBER 31, 1999 AND 1998

SALES. The Company's sales consist of revenue recognized for services performed.
Sales decreased $10.0 million to $16.8 million for the first three months of
fiscal 2000 from $26.9 million for the first three months of fiscal 1999 as a
result of a reduction of new contract signings during fiscal 1999. Management
believes these market conditions were caused by consolidation in the utility
industry, year 2000 computer concerns and increased competition from companies
with offshore operations.

SALARIES, WAGES AND RELATED BENEFITS. Salaries, wages and related benefits
includes employee compensation for production, marketing, selling,
administrative and executive employees. Salaries, wages and related benefits
decreased 12.2% to $12.5 million for the first three months of fiscal 2000 from
$14.3 million for the first three months of fiscal 1999, as a result of
reductions in its workforce. The reductions in the workforce were a result the
Company's decision to subcontract a higher percentage of its production work to
offshore subcontractors. As a percentage of sales, salaries, wages and related
benefits increased to 74.5% for the first three months of fiscal 2000 from 53.2%
for the first three months of fiscal 1999, as reductions in the workforce were
insufficient to offset the reduced sales volume.

SUBCONTRACTOR COSTS. Subcontractor costs includes production costs incurred
through the use of third parties for production tasks, such as data conversion
services to meet contract requirements, aerial photography and ground and
airborne survey services. Subcontractor costs decreased 20.1% to $3.0 million
for the first three months of fiscal 2000 from $3.7 million for the first three
months of fiscal 1999, and increased as a percentage of sales to


                                       8
<PAGE>   9


17.6% for the first three months of fiscal 2000 from 13.8% for the first three
months of fiscal 1999. While overall subcontractor costs declined because of
lower sales volume, the percentage of subcontractor costs to total costs was
higher as a result of the Company's transition to subcontracting a greater
percentage of its production offshore.

OTHER GENERAL AND ADMINISTRATIVE COSTS. Other general and administrative costs
includes rent, maintenance, travel, supplies, utilities, insurance and
professional services. Such costs decreased 14.9% to $3.7 million for the first
three months of fiscal 2000 from $4.4 million for the first three months of
fiscal 1999, as a result of reductions in force. As a percentage of sales, other
general and administrative costs increased to 22.1% for the first three months
of fiscal 2000 from 13.8% for the first three months of fiscal 1999. While other
general and administrative costs declined overall, they increased as a
percentage of costs due to significantly lower sales in the three months ended
December 31, 2000 compared to the same period in the prior year.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization consists primarily
of amortization of goodwill incurred in connection with the Company's
acquisitions, as well as depreciation of certain of the Company's operating
assets. For the first three months of fiscal 2000, depreciation and amortization
decreased 7.2% to $1.25 million from $1.35 million for the first three months of
fiscal 1999. As a percentage of sales, depreciation and amortization increased
to 7.4% for the first three months of fiscal 2000 from 5.0% in the first three
months of fiscal 1999.

OTHER EXPENSE, NET. Other expense, net is comprised primarily of net interest
expense. Net interest expense decreased 27.5% to $501,000 for the first three
months of fiscal 2000 from $691,000 for the first three months of fiscal 1999,
as a result of reduced borrowing outstanding, offset in part by higher interest
rates.

INCOME TAXES. Income tax benefit was $1.5 million for the first three months of
fiscal 2000 compared to an expense of $1.1 million for the first three months of
fiscal 1999. The Company's effective income tax rate for the first three months
of fiscal 2000 was 35.5%, a decrease from 43.4% for the first three months of
fiscal 1999.



LIQUIDITY AND CAPITAL RESOURCES

Historically, the Company's principal source of liquidity has consisted of cash
flow from operations supplemented by secured lines of credit. As of December 31,
1999, the Company had not drawn on its line of credit. During 1998, the Company
replaced its existing lines of credit with a three-year, $21.0 million secured
working capital line of credit and the Company refinanced $25.4 million of term
debt. Borrowings under these credit facilities bear interest at a rate per annum
equal to, at the Company's option, (i) the agent bank's prime rate or (ii) an
adjusted London Interbank Offering Rate (LIBOR) plus a margin ranging from 1.25%
to 1.75%. The effective borrowing rate was approximately 7% on December 31,
1999.

The Company's loan agreement was amended on March 6, 2000 to establish new
covenants requiring the Company to maintain a minimum of $25 million in net
tangible assets and to achieve a minimum level of profitability for the three
remaining quarters of fiscal 2000. The amended agreement also reduced the line
of credit to a maximum of $7.5 million based on eligible accounts receivable,
increased the interest rate to LIBOR plus 3%, and accelerated the final maturity
of the balance of the term loan to February 2001.

The Company's cash flow is significantly affected by three contract-related
accounts: accounts receivable; revenues in excess of billings; and billings in
excess of revenues. Under the percentage of completion method of accounting, an
"account receivable" is created when an amount becomes due from a customer,
which typically occurs when an event specified in the contract triggers a
billing. "Revenues in excess of billings" occur when the Company has performed
under a contract even though a billing event has not been triggered. "Billings
in excess of revenues" occur when the Company receives an advance or deposit
against work yet to be performed. These accounts, which represent a significant
business investment, affect the Company's cash flow as projects are signed,
performed, billed and collected.

Net cash used by the Company's operating activities was $3.4 million and $0.8
million for first three months of fiscal years 1999 and 2000, respectively. The
change in operating cash flows is primarily attributable to normal fluctuations
in the contract-related accounts described in the previous paragraph. At
December 31, 1999, the working capital in contract-related accounts was
equivalent to 215 days sales outstanding, up from 202 days at


                                       9

September 30, 1999. The Company believes that this level of investment is at the
high end of the normal operating range of days sales outstanding.

Cash used by investing activities for the first three months of fiscal years
2000 and 1999 was $0.4 million and $1.2 million, respectively. Such investing
activities principally consisted of payments for purchases of equipment and
leasehold improvements.

Cash used by financing activities for the first three months of fiscal year 2000
was $1.5 million as compared to $4.5 million provided by financing activities
for the first three months of fiscal 1999. Financing activities consisted
primarily of net borrowings and payments under lines of credit for working
capital purposes and net borrowings and payments of long-term debt used for
business combinations and the purchase of equipment and leasehold improvements.

The Company believes that funds available under its lending arrangements and
cash flow from operations are adequate to finance its operations for at least
the next twelve months.



YEAR 2000 ISSUES

The "Year 2000" issue is the result of computer programs using two digits,
rather than four, to define the applicable year. The failure of such programs to
recognize the year 2000 as such could result in systems failures and
miscalculations. The Company and the third parties with which it does business
rely on numerous computer programs in their daily operations.

To the best of its knowledge, the Company believes that neither it nor any of
its customers or key suppliers experienced any adverse impact due to Year 2000
problems.



ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The Company may from time to time employ risk management techniques such as
interest rate swaps and foreign currency hedging transactions. None of these
techniques are used for speculative or trading purposes and the amounts involved
are not considered material.

Short-term interest rate changes can impact the Company's interest expense on
its variable interest rate debt. Variable interest rate debt of $20.7 million
was outstanding as of December 31, 1999. Assuming December 31, 1999 debt levels,
an increase or decrease in interest rates of one percentage point would impact
the Company's interest expense by $207,000.



                                     PART II

ITEM 1.  LEGAL PROCEEDINGS.

The Company and certain of its present and former officers and employees (the
"Individual Defendants") have been named as defendants in several putative
securities class actions filed in the United States District Court for the
Southern District of Indiana, beginning February 2, 2000. Plaintiffs in each of
the actions allege that the defendants violated Section 10(b) of the Exchange
Act, and SEC Rule 10b-5 promulgated thereunder, alleging that they misstated or
omitted to state material facts concerning the Company's operations and
financial results in the Company's financial statements filed with the SEC, and
in press releases and other public statements, issued during the period from
January 25, 1999, through January 27, 2000 (the "putative class period").
Plaintiffs seek to represent themselves and a class of all public investors who
purchased or otherwise acquired common stock of the Company during the putative
class period and who suffered damages thereby, and seek an award of compensatory
damages and attorneys' fees and costs.

It is expected that the various actions will be consolidated before one judge,
and that plaintiffs then will file a single, consolidated class action
complaint. Because this litigation is at an early stage, it is impossible to
evaluate the impact that the above actions, or any future, related actions, may
have on the Company. However, it is reasonably possible that an unfavorable
outcome in the present litigation, or in any related future actions, could have
a material

adverse impact on the Company's financial condition or results of operations in
one or more future reporting periods. The Company and the Individual Defendants
intend to defend themselves vigorously in this litigation.
