INSIDE FRONT COVER
 
The inside front cover of the prospectus features nine photographs broken into
three sets, with each set running horizontally under a block of text. At the top
of the page, the following paragraph describes a geographic information system:
 
       "A geographic information system is a high-resolution, large scale
       (e.g., one inch = 100 feet), richly detailed `intelligent map'
       that allows users to input, update, query, analyze and display
       information about a geographic area. A GIS integrates database
       operations, such as query and statistical analyses, with the
       unique visualization and geographic analyses offered by paper
       maps."
 
The first set of photographs is of the GIS data gathering process and runs under
the following text:
 
       "The Company provides an experienced field inventory staff to
       collect and verify information in the field and uses computerized
       and manual techniques to verify and digitize data from paper
       sources."
 
Image #1 is an aerial photograph of streets and homes within a neighborhood.
Image #2 is a photograph of two men near a fire hydrant working with global
positioning equipment. Image #3 is a photograph of a man viewing a series of
maps spread out on a light table.
 
The second set of photographs depicts the GIS data conversion process and runs
under the following text:
 
       "The Company offers a full range of services to create the digital
       base maps and databases of related geo-referenced information used
       in geographic information systems. The base maps are created using
       one of three technologies, depending on the needs of the customer:
       photogrammetric mapping, digital orthophotography or cadastral
       mapping."
 
Image #4 is a photograph of a man working on a computer while looking into a
viewing device. Image #5 is of a man sitting and working among several
specialized computer terminals and scanning devices. Image #6 is of a man
working at a computer and performing conversion work on a digitized aerial
photograph.
 
The third and final set of photographs is of on-screen GIS images and runs under
the following text:
 
       "Once the base map is produced, links to tabular databases are
       created and other geo-referenced data, such as buildings,
       telephone poles and zoning restrictions, are collected, verified,
       converted into digital format and added to the base map to create
       a GIS. Once a GIS is completed, the user can view the base map and
       any or all of the layers of data on a computer screen and can
       retrieve selected data concerning any desired location appearing
       on the screen or all data matching one or more variables."
 
Image #7 shows property lines and street locations of a neighborhood. Image #8
is an aerial photograph of a highway and the surrounding buildings. Colored,
computerized lines in the image show the location of various utilities and
property boundaries. Image #9 is a digital map that includes lines depicting
contours, roads, buildings and other features.
<PAGE>
TWO-PAGE GATEFOLD
 
Page one of this two-page gatefold features four digital images taken from a GIS
developed for the New York City Department of the Environment.
 
The following text accompanies the images:
 
       "The images on this page are from a GIS pilot project Analytical
       Surveys completed for the New York City Department of the
       Environment. The images depict various features -- such as water
       mains, road edges and buildings -- within lower Manhattan. To
       create the images, ASI collected extensive data on the physical
       characteristics of various features and then converted the
       information into multiple layers of digital data.
 
       "Image #1 depicts the location of water mains and manholes. In
       Image #2, road edges and centerlines have been layered on top of
       the waterline information. A river and piers have been added in
       Image #3, and in Image #4, a digital orthophoto has been draped
       over the information from the three previous images."
 
       "The GIS serves a variety of functions, including management of
       sewer and water data, emergency repair management and maintenance
       scheduling."
 
All four images feature the same 2- to 3-square-block area as well as part of
the shore line of the East River. However, each image features a different
"layer" of geo-referenced information. The images appear to be floating above
one another, visually emphasizing the idea of each image being a distinct layer.
Image #1, which appears as the bottom layer of the four images, shows the
locations of water lines and manholes. Image #2 shows all road edges, as well as
the features from image #1. Image #3 shows the shore of the East River and two
piers stretching into the river, as well as all of the information from the
first two images. Image #4 adds an overhead aerial photograph of the area mapped
in the first three images.
 
Also on the page is a 3-D model of the lower east side of Manhattan as if viewed
from a distance.
 
Page two of the gatefold features another set of four digital images layered in
the same fashion as was used on page one of the gatefold. These images were
taken from a GIS project conducted for Illinois Power.
 
The following text accompanies the images:
 
       "This series of images is from a utility mapping project conducted
       by the Company for Illinois Power. Aerial photographs were taken
       of the project area and served as the base on which the GIS was
       built.
 
       "Image #1 includes various landbase features such as
       rights-of-way, streets and property lines. Image #2 adds primary
       electric features such as conductors, transformers and
       substations. Features associated with the gas distribution
       network, such as mains, valve fittings and services, have been
       added in Image #3. Finally, in Image 4, secondary electric
       features are overlaid, including ducts, manholes, vaults and
       poles."
 
       "Uses of this GIS range from outage identification and management
       to maintenance scheduling to mapping new service areas."
 
As described in the text that accompanies the imaging, Image #1 is of various
landbase features such as rights-of way, streets and property lines. Image #2
adds primary electric features such as conductors and transformers. Image #3
adds features from the gas distribution network. Image #4 adds secondary
electric features such as manholes, vaults and poles.

                                  THE COMPANY
 
    Analytical Surveys, Inc. ("ASI" or the "Company") is a leading provider of
customized data conversion and digital mapping services for the geographic
information systems market. A geographic information system ("GIS") is a
high-resolution, large-scale, richly detailed "intelligent map" that allows
users to input, update, query, analyze and display detailed information about a
geographic area. Geographic information systems are widely used by utilities,
state and local governments, federal agencies and commercial businesses to
manage massive infrastructures effectively, to improve operating efficiencies
and to analyze future demand for facilities. The Company primarily targets
utilities and state and local governments, and its current customers include the
New York City Department of the Environment, Florida Power & Light, Michigan
Consolidated Gas, Southern New England Telephone, U S WEST, British Telecom and
FirstEnergy Corp. (formerly known as Ohio Edison).
 
    The Company believes that the market for geographic information systems is
experiencing substantial growth due to a number of factors, including: growing
awareness of the benefits of GIS technology; significant reductions in computer
hardware prices; increased capability and reliability of hardware and software;
deregulation and consolidation in the utility industry; and increased demand for
geographic information systems in growing communities. In addition, the Company
believes that GIS users are increasingly outsourcing their data conversion and
other GIS services projects to large third-party providers such as ASI. The
Company provides its customers with a single source for all data conversion
services necessary in the production of a customized GIS.
 
    Frost & Sullivan, an industry research firm, estimates that the global GIS
market will grow from $4.5 billion in 1997 to $8.1 billion by 2002. Frost &
Sullivan identifies five segments within the GIS market: software for personal
computers; software for work stations; software for mainframes; data; and
services (which includes consulting, systems integration, database design, data
collection and data conversion). The Company competes primarily in the data
conversion and collection portions of the GIS services industry. Frost &
Sullivan estimates that the GIS services market, which represents approximately
70% of the global GIS market, will grow from $3.2 billion in 1997 to $5.5
billion in 2002.
 
    The GIS services business is very competitive and highly fragmented. The
Company's competitors include small regional firms, large independent firms,
large companies with GIS services divisions, customer in-house operations and
international providers of data conversion services. The Company
 
                                       3
<PAGE>
believes that many of the businesses in the GIS services industry do not have
adequate access to capital for expansion, lack the capacity to complete large,
long-term projects and do not have the technical expertise or experience that
customers increasingly require of their GIS services vendors. As a result, the
Company believes that the industry is poised for consolidation.
 
    In 1995, ASI embarked on its current growth strategy, which includes
consolidation of the fragmented GIS services industry. To date, the Company has
completed four strategic acquisitions that have expanded the Company's
geographical scope, capacity, customer base, product offerings, proprietary
technology and operational expertise. The Company acquired Intelligraphics, Inc.
("Intelligraphics") located in Wisconsin in December 1995; Westinghouse Landmark

                                  RISK FACTORS
 
    THE COMMON STOCK OFFERED BY THIS PROSPECTUS INVOLVES A HIGH DEGREE OF RISK.
IN ADDITION TO THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, THE RISK
FACTORS DESCRIBED BELOW SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN
INVESTMENT IN THE SHARES OF COMMON STOCK OFFERED BY THIS PROSPECTUS.
 
RISKS ASSOCIATED WITH ACQUISITION STRATEGY
 
    A major component of the Company's strategy is the acquisition of
complementary GIS services businesses. The Company acquired Intelligraphics in
December 1995; ASI Landmark in July 1996; MSE in July 1997; and Cartotech in
June 1998. Acquisitions involve a number of special risks, including, but not
limited to, potential adverse short-term effects on the Company's operating
results, diversion of management's attention, the loss of key personnel, risks
associated with the assimilation of the operations and personnel of the acquired
companies, unanticipated business problems or legal liabilities and amortization
of acquired intangible assets. In addition, when the Company acquires another
business, it assumes the obligation to complete the acquired company's contracts
that are in process. The Company's results of operations following any
acquisition will depend, in part, on the ability of the Company to profitably
complete such contracts, which could be adversely affected by the acquired
company's underestimation of the cost or amount of work required to complete the
project as well as additional costs necessary to correct problems associated
with the acquired company's prior performance. The success of the Cartotech
acquisition in particular may depend to a substantial degree on the ability of
the Company to profitably complete a project for the largest customer of
Cartotech. There is no assurance that the Company will be able to integrate
Cartotech or other acquired businesses into the Company without substantial
costs, delays or other operational or functional difficulties, or to obtain the
synergies expected from such acquisitions. Some or all of these risks could have
a material adverse effect on the Company. In addition, there can be no assurance
that the Company will be able to identify and acquire additional strategic
businesses, and, to the extent that consolidation becomes more prevalent in the
GIS services industry, the prices for attractive acquisition candidates may
reach unacceptably high levels. The inability of the Company to implement and
manage its acquisition strategy successfully for the reasons set forth above or
for other reasons would have an adverse effect on the Company. See "--Risks
Associated with Terms of Customer Contracts," "Business--Strategy" and
"Business--Recent Acquisitions."
 
ABILITY TO MANAGE GROWTH
 
    The Company has grown substantially since 1996 and, in particular, since its
acquisition of MSE in July 1997. An integral part of the Company's strategy is
to continue its growth, primarily as a result of acquisitions and increased
sales by the Company to new and existing clients. To the extent that the Company
is able to continue to grow, its ability to manage any such growth will be
critical to its success and will require the establishment of financial controls
and accounting procedures at the acquired companies and the control of
acquisition-related overhead generally, the continued enhancement of
operational, financial and information systems, and the attraction and retention
of additional management and trained personnel. There can be no assurance that
the Company will be able to manage expanded operations effectively, and its
failure to do so would have a material adverse effect on the Company. See
"--Risks Associated with Acquisition Strategy" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
COMPETITION
 
    The GIS services business is very competitive and highly fragmented. The
Company's competitors include small regional firms, independent firms, large
companies with GIS services divisions, customer in-house operations and
international low-cost providers of data conversion services. Additionally, as
the GIS services industry evolves, additional competitors with greater resources
than the Company may enter the industry. Several large companies with
substantial financial resources are in the process of launching
 
                                       6
<PAGE>
satellites with imagery technology that provides much more detailed photographs
than have been available with such technology in the past. Although current
commercially available satellite imagery does not provide the degree of
resolution required by most of the Company's customers, if such technology
becomes commercially available, satellite companies may attempt to enter the GIS
services business or could form strategic alliances with the Company's
competitors, and thereby could pose a substantial competitive threat to the
Company. In addition, other improvements in technology could provide competitors
or customers with tools to perform the services provided by the Company and
lower the cost of entry into the GIS services industry. A number of the
Company's competitors or potential competitors have capabilities and resources
greater than those of the Company. See "--Dependence on Business Alliances" and
"Business--Competition."
 
RISKS ASSOCIATED WITH TERMS OF CUSTOMER CONTRACTS
 
    Virtually all of the Company's revenue is earned under long-term,
fixed-price contracts. The Company's contractual obligations typically include
several large projects that will extend over one to four years. The Company's
ability to estimate its costs accurately when negotiating the overall price of a
project is critical to ensuring the profitability of such project. The Company
must also control the costs of performance under such fixed-price contracts. As
the Company increases its marketing efforts to obtain larger projects, the needs
to estimate costs accurately and to control costs of performance become more
important. Schedule delays resulting from a customer's lack of available funding
or schedule compressions required by customers may place additional strains on
management to hire and train the personnel required for project completion. The
Company's contracts with its customers are generally terminable by the customer
on relatively short notice, and customers may request that the Company slow down
or scale back the scope of a project in order to satisfy the customer's budget
or cash flow requirements. In addition, the Company could experience material
contract terminations or slowdowns. Long-term, fixed-price contracts for larger
projects generally increase the Company's risk due to inflation. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Customer Contracts."
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS; VOLATILITY OF STOCK PRICE
 
    The Company has experienced and expects to continue to experience quarterly
variations in sales and operating income as a result of many factors, including
the effects of acquisitions, timing of customers' budget processes, slowdowns or
acceleration of work by customers, the number of operating days in each quarter
and the impact of weather conditions on the ability of subcontractors to obtain
satisfactory aerial photography. In addition, the Company has in the past
experienced lower sales in its first fiscal quarter (ended December 31) due to
certain customers' year-end funding constraints, seasonal limitations on
obtaining aerial photography and seasonal slowdowns associated with the year-end
holidays. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Quarterly Results."
 
    The Common Stock has experienced, and is likely to continue to experience
significant price and trading volume fluctuations. The trading price of the
Common Stock has been and may continue to be subject to significant fluctuations
in response to actual or anticipated variations in the Company's quarterly
operating results and other factors, such as: the introduction of new services
or technologies by the Company or its competitors; changes in other conditions
in the GIS industry or in the industries of any of the Company's customers;
changes in governmental regulation, government spending levels or budgetary
procedures; changes in securities analysts' estimates of the future performance
of the Company, its competitors or the industry generally; or general market
conditions. The trading price of the Common Stock may vary without regard to the
operating performance of the Company. General market price declines or market
volatility in the future, or future declines or volatility in the prices of
stock for companies in the GIS industry, also could affect the market price of
the Common Stock. See "Price Range of Common Stock."
 
                                       7
<PAGE>
RELIANCE ON TECHNOLOGY; LIMITED PROTECTION OF PROPRIETARY RIGHTS
 
    The Company has devoted significant resources to developing and acquiring
specialized data conversion hardware and software. In order to remain
competitive, it will be necessary for the Company to continue to select, invest
in, acquire and develop new and enhanced technology on a timely basis. There can
be no assurance that the Company will be successful in these efforts or in
anticipating developments in data conversion technology. Although the Company
believes that its operating procedures and proprietary software have been
important factors in its success, the technology used by the Company in
developing its proprietary software is readily available to, or could legally be
duplicated by, its competitors. The Company does not have any patent protection
for its products or technology. Although the Company relies to a great extent on
trade secret protection for much of its technology and has obtained
confidentiality agreements from most of its employees, third parties could
independently develop similar technology, obtain unauthorized access to the
Company's proprietary technology or misappropriate technology to which the
Company has granted access. See "Business--Strategy" and "Business--Research and
Development."
 
DEPENDENCE ON CERTAIN CUSTOMER MARKETS
 
    The Company derives its revenues primarily from two core markets, utilities
and state and local governments, and also serves federal agencies and commercial
businesses. The ongoing consolidation of the utility industry could increase
competition for the GIS services projects of the utilities that remain. Also, to
the extent that utilities remain regulated, legal, financial and political
considerations may constrain the ability of utilities to fund geographic
information systems. Many state and municipal entities are subject to legal
constraints on spending, and a multi-year contract with any such entity may be
subject to termination in any subsequent year if the entity does not choose to
appropriate funds for such contracts in that year. Moreover, fundamental changes
in the business practices or capital spending policies of any of these
customers, whether due to budgetary, regulatory, technological or other
developments or changes in the general economic conditions in the industries in
which they operate, could cause a material reduction in demand by such customers
for the services offered by the Company. Any such reduction in demand could have
a material adverse effect on the Company. See "Business--Customers."
 
DEPENDENCE ON INTERNAL LABOR FORCE
 
    The Company's business is labor-intensive and requires trained employees. In
order to support additional growth, if any, the Company must increase production
capacity by the addition of more employees. There can be no assurance that the
Company will be able to continue to hire, train and retain sufficient numbers of
qualified employees. A significant portion of the Company's costs consists of
wages to hourly workers. An increase in hourly wages, costs of employee benefits
or employment taxes could have a material adverse effect on the Company.
Although the Company believes that its employee turnover rate is at an
acceptable level, turnover could increase for any of several reasons, including
the disruption that is sometimes associated with the acquisition of businesses
and increased competition for labor in any geographic area where the Company
operates. A higher turnover rate among the Company's employees would increase
the Company's recruiting and training costs, could affect the Company's ability
to perform services and earn revenues on a timely basis, and could decrease
operating efficiencies and productivity. See "Business--Personnel."
 
DEPENDENCE ON SUBCONTRACTORS
 
    ASI employs certain selected subcontractors for tasks outside its expertise,
such as aerial photography and ground survey. The Company also uses
subcontractors for work similar to that performed by ASI employees in order to
expand capacity, meet deadlines, reduce production costs, manage work load and
encourage businesses owned by women and minorities. The inability to obtain
services of such subcontractors when needed or at all could have a material
adverse effect on the Company. See "Business-- Subcontractors."
 
                                       8
<PAGE>
RISKS RELATING TO INTERNATIONAL SALES
 
    In fiscal 1997, revenues from international sales represented approximately
6.3% of the Company's total revenues. The Company intends to continue expanding
its operations outside the United States and to enter additional international
markets, which will require management's attention and financial resources. If
foreign sales become a more significant component of the Company's net sales,
the Company's business will become more vulnerable to the inherent risks of
doing business internationally, including increased difficulties in collection
of accounts receivable, unexpected changes in regulatory requirements, tariffs
and other trade barriers, fluctuations in currency exchange rates, potentially
adverse tax consequences and political instability. The existence or occurrence
of any one of these factors could have a material adverse effect on the Company.
See "Business--Strategy" and "Business--Sales and Marketing."
 
DEPENDENCE ON BUSINESS ALLIANCES
 
    A significant portion of the Company's sales is the result of referrals
derived, either directly or indirectly, from consultants in the GIS industry.
The Company believes that its continued success in the GIS services market is
dependent, in part, on its ability to maintain current relationships and to
cultivate additional relationships with other leading consultants. Such
consultants could independently acquire a GIS data collection or data conversion
business or businesses or form other relationships with the Company's
competitors. There can be no assurance that relationships with GIS consultants
will continue to be a source of business for the Company. The inability of the
Company to maintain such relationships or to form new relationships could have a
material adverse effect on the Company. See "Business--Sales and Marketing."
 
DEPENDENCE ON KEY PERSONNEL
 
    The success of the Company depends in large part upon the continued service
of its executive officers and other key employees. While the Company has
employment agreements with certain of its key personnel, there is no assurance
that the Company will be able to retain the services of such key personnel. The
Company does not maintain any key person life insurance policies. Moreover, in
order to support additional growth, if any, the Company will be required to
recruit, develop and retain additional qualified management personnel. The loss
of key personnel or the inability to obtain additional key personnel could have
a material adverse effect on the Company.
 
DEPENDENCE ON OFFSHORE OPERATIONS
 
    The Company utilizes operations in Mumbai, India to perform certain data
capture tasks at lower costs than could be achieved in the United States. These
operations were acquired in May 1998. Expenses incurred by these operations
represented approximately 7% of subcontractor expenses for the three-month
period ended March 31, 1998. Although the Company believes that it could replace
the personnel in India, and while the amounts paid for the performance of
services overseas have not, to date, been material, the ability of the Company
to perform services under some existing contracts on a profitable basis is
dependent upon the continued availability of its overseas operations. In the
past, India has experienced significant inflation as well as civil unrest and
regional conflicts. India's recent testing of nuclear devices has resulted in
the imposition of economic sanctions by the United States, and it is not known
what effect these events might have on the attitude of the Indian government
toward U.S. businesses in India. Moreover, the Indian government has exercised
and continues to exercise significant influence over many aspects of the Indian
economy. Events or governmental actions that would impede or prohibit the
operations of the Company's Mumbai facility could have a material adverse effect
on the Company. See "Business--Personnel" and "Business-- Subcontractors."

SHARES ELIGIBLE FOR FUTURE SALE
 
    Sales of substantial amounts of Common Stock in the public market after this
offering could adversely affect the market price of the Common Stock. Upon
completion of this offering, there will be 8,437,327 shares of Common Stock
outstanding. Of these shares, 7,196,116 will be freely tradeable without
restriction. On June 27, 1999 and June 27, 2000, an aggregate of 238,743 and
115,424 shares, respectively, will become eligible for sale in the public market
upon the expiration of certain lock-up agreements entered into in connection
with the Cartotech acquisition. In addition, the holders of an aggregate of
887,044 shares of Common Stock have agreed, pursuant to certain lock-up
agreements entered into in connection with this offering, not to offer or sell
any shares of Common Stock of the Company for a period of 90 days following the
date of this Prospectus without the prior written consent of NationsBanc
Montgomery Securities LLC. Upon the expiration of these lock-up agreements with
NationsBanc Montgomery Securities LLC and subject in each case to provisions of
Rule 144 under the Securities Act, (i) 262,044 of these shares will be eligible
for sale in the public market, and (ii) the remaining 625,000 shares will be
eligible for sale on July 2, 1999 upon the expiration of a lock-up agreement
entered into in connection with the MSE acquisition. Holders of approximately
863,743 shares of "Restricted Securities " (as such term is defined in the
Securities Act) are entitled to certain incidental and demand registration
rights with respect to registration of such shares for offer or sale to the
public. To the extent that such registration rights are exercised, the number of
shares freely tradeable in the public market will increase, which could
adversely affect the market price of the Common Stock. See "Principal and
Selling Shareholders" and "Shares Eligible for Future Sale."
 
    The Company has registered for issuance or resale the 2,878,000 shares of
Common Stock reserved for issuance under the Company's stock option plans. As of
May 31, 1998, options to purchase 1,744,000 shares had been granted and were
outstanding under the Company's stock option plans, of which options to purchase
513,000 shares were currently exercisable. Options to purchase the remaining
1,231,000 shares become exercisable at varying times thereafter.
 
DISCRETIONARY USE OF PROCEEDS OF OFFERING
 
    The Company has no current specific plans for use of the net proceeds of
this offering, other than approximately $31.5 million that the Company intends
to use to repay the amounts outstanding under the Company's term loan and lines
of credit. As a consequence, the Company's management will have the ability to
allocate the remainder of the net proceeds of this offering in its discretion.
There can be no assurance that the net proceeds will be utilized in a manner
that the shareholders deem optimal or that the net proceeds can or will be
invested to yield a significant return following the completion of this
offering. See "Use of Proceeds."
 
EFFECT OF PREFERRED STOCK PROVISIONS
 
    The Company's articles of incorporation allow the Board of Directors to
issue up to 2,500,000 shares of preferred stock and to fix the rights,
privileges and preferences of those shares without any further vote or action by
the shareholders. The rights of the holders of Common Stock will be subject to,
and may be adversely affected by, the rights of the holders of any preferred
stock that may be issued by the Company in the future. Although the Company has
no present intention to issue any preferred stock, any such issuance could be
used to discourage an unsolicited acquisition proposal by a third party.

                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the 1,750,000 shares of
Common Stock offered by the Company hereby are estimated to be approximately
$60.3 million, assuming a public offering price of $37.00 per share, after
deduction of the underwriting discount and estimated offering expenses payable
by the Company. Approximately $31.5 million of the net proceeds of the offering
is expected to be used to repay the amounts outstanding under the Company's term
loan and lines of credit. At June 26, 1998 there was approximately $16.0 million
outstanding under the term loan, which expires June 2003; $8.3 million under the
acquisition line of credit, which expires June 2003; and $7.2 million under the
working capital line of credit, which expires June 2001. These credit facilities
bear interest at a rate equal to, at the Company's option; either the London
Interbank Offering Rate plus a margin of between 1.25% to 2.25%; or the lender's
prime rate. The Company incurred $12.5 million in borrowed funds in connection
with the acquisition of MSE in July 1997 and approximately $8.3 million in
connection with the acquisition of Cartotech in June 1998. The remaining net
proceeds of the offering are expected to be used for working capital and other
general corporate purposes. A portion of the net proceeds may also be used for
strategic acquisitions of businesses and technologies complementary to those of
the Company. The Company has no present agreements or commitments and is not
currently engaged in any negotiations with respect to any acquisition. See "Risk
Factors--Discretionary Use of Proceeds of Offering" and "Management's Discussion
and Analysis of the Results of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
    Pending the uses described above, the Company intends to invest the net
proceeds from this offering in short-term, interest bearing, investment-grade
securities. The Company will not receive any proceeds from the sale of shares of
Common Stock by the Selling Shareholders.

OVERVIEW
 
    ASI, a leading provider of data conversion and digital mapping services to
users of customized geographic information systems, was founded in 1981 by its
current Chief Technical Officer, John A. Thorpe. From 1981 to 1990, the Company
experienced steady growth in revenues with periodic fluctuations in financial
results. After the hiring of the Company's current Chief Executive Officer and
Chief Financial Officer in 1990, the Company implemented a controlled growth
strategy, including improving and standardizing operating controls and
procedures, investing in infrastructure, upgrading the Company's proprietary
software and establishing capital sources.
 
    In 1995, the Company embarked on a more aggressive growth strategy,
including consolidation of the fragmented GIS services industry. The Company
acquired substantially all of the assets of Wisconsin-based Intelligraphics,
Inc. ("Intelligraphics") in December 1995 for $3.5 million in cash and 345,000
shares of restricted Common Stock valued at $891,000. Intelligraphics, with over
200 employees, significantly expanded the Company's capacity to perform large
projects, added utility industry expertise, and established ASI's presence in
the midwestern United States. The acquisition contributed over 25 new customers
and $12.3 million in "backlog," which represents the amount of revenue that has
not been recognized on signed contracts.
 
    In July 1996, the Company expanded its services to state and local
governments by acquiring substantially all of the assets of Westinghouse
Landmark GIS, Inc. ("ASI Landmark") for $2.0 million in cash. Based in North
Carolina, ASI Landmark's primary business is land base and cadastral mapping.
Prior to this acquisition, ASI had utilized subcontractors for certain of these
services. ASI Landmark also provided the Company with additional capacity for
photogrammetry, and a presence in the eastern and southeastern United States.
The acquisition contributed approximately 20 new customers, $9.1 million in
backlog and 105 employees to the Company.
 
    The Company acquired MSE Corporation ("MSE") in July 1997 for $12.5 million
in cash and 925,000 shares of restricted Common Stock valued at $7.3 million.
The acquisition of Indiana-based MSE gave the Company greater capacity to serve
the utility market and further enhanced ASI's presence in the midwestern United
States. In addition, the acquisition of MSE contributed over 200 customers and
$43.0 million of backlog to the Company. Over 325 employees joined the ASI
workforce as a result of the MSE acquisition, including the Company's current
Chief Operations Officer and Chief Administrative Officer.
 
                                       15

    The Company acquired Texas-based Cartotech, Inc. ("Cartotech") in June 1998
for approximately $7.7 million in cash, net of cash acquired, and 354,167 shares
of restricted Common Stock valued at approximately $8.3 million. The Cartotech
acquisition extended ASI's presence in the utility market, enhanced the
Company's field inventory operations and provided the Company with a strong
presence in the southwestern United States. The Cartotech acquisition
contributed over 50 new customers and 270 employees to the Company. One of
Cartotech's customers, FirstEnergy Corp. (formerly known as Ohio Edison),
accounted for approximately 46.0% of Cartotech's revenues in calendar 1997.
 
    In conjunction with the above acquisitions, the Company has recorded
goodwill, which represents the excess of the purchase price over the fair value
of the net assets acquired in business combinations. As of March 31, 1998,
goodwill, net of accumulated amortization, was $11.9 million. The Company
expects to record approximately $15.0 million of goodwill in connection with the
Cartotech transaction. The Company will amortize the value of the intangible
assets acquired in its recent business acquisitions over a period of 15 years,
representing the expected period of benefit from the acquisitions. The Company
believes this amortization period to be appropriate based on the historical and
forecasted operating results of the acquired businesses.
 
    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. 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.
 
    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. As a result, the Company experiences yearly and
quarterly fluctuations in production costs, in salaries, wages and related
benefits and in subcontractor costs. These costs may vary as a percentage of
sales from period to period. Since 1995 the Company has relied less on
subcontractors and more on employees. The Company anticipates that, as a
percentage of sales, salaries, wages and related benefits will continue to
increase, with a corresponding decrease in subcontractor costs, due, in part, to
the Company's May 1998 purchase of Interra Technologies, an India-based company
that had been a provider of subcontractor services to the Company. The following
table illustrates the relationship of salaries, wages and related benefits and
subcontractor costs:

    The Company recognizes losses on contracts in the period such loss is
determined. From the beginning of fiscal 1995 through the six month period
ending March 31, 1998, the Company has recognized aggregate losses on contracts
of approximately $922,000. Over the same period, the Company recognized sales of
$114.4 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 March 31, 1998, backlog was $99.0 million. Recently, the
number of large projects awarded to the Company has increased. Contracts for
larger projects generally increase the Company's risk due to inflation as well
as changes in customer expectations and funding availability. The Company's
contracts are
 
                                       16
<PAGE>
generally terminable on short notice, and while in the Company's experience such
termination is rare, there is no assurance that the Company will receive all of
the revenue anticipated under signed contracts. See "Risk Factors--Risks
Associated with Terms of Customer Contracts" and "Business--Customer Contracts."
 
    The Company engages in significant 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 fiscal 1997 and for the six months ended March 31, 1998,
the Company expended $275,000 and $120,000, respectively, on such independent
research and development activities.

</TABLE>
 
    SIX MONTHS ENDED MARCH 31, 1998 AND 1997
 
    SALES.  The Company's sales consist of revenue recognized for services
performed. Sales increased $21.2 million or 131.1% to $37.4 million for the six
months ended March 31, 1998 from $16.2 million for the six months ended March
31, 1997. This increase was due to an increase in the number and size of
customer contracts with the Company (including MSE) as well as the impact of the
acquisition of MSE in July 1997. Prior to its acquisition by the Company, MSE's
sales for the six months ended March 31, 1997 were $11.7 million.
 
    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
increased 142.6% to $18.4 million for the six months ended March 31, 1998 from
$7.6 million for the six months ended March 31, 1997. This increase was
primarily due to the addition of over 325 employees as a result of the MSE
acquisition in July 1997, as well as the hiring of additional
 
                                       17
<PAGE>
employees to support the Company's increased business. As a percentage of sales,
salaries, wages and related benefits increased to 49.3% for the six months ended
March 31, 1998 from 47.0% for the six months ended March 31, 1997. This
increase, and the corresponding decrease in subcontractor costs, was primarily
attributable to the Company's increased capability to perform more tasks
internally as well as a decrease in the number of projects which required
subcontractor services. The Company anticipates that, as a percentage of sales,
salaries, wages and related benefits will continue to increase, with a
corresponding decrease in subcontractor costs, due, in part, to the Company's
May 1998 purchase of Interra Technologies, an India-based company that had been
a provider of subcontractor services to the Company.
 
    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 increased 43.5% to $4.3 million
for the six months ended March 31, 1998 from $3.0 million for the six months
ended March 31, 1997, but decreased as a percentage of sales to 11.6% for the
six months ended March 31, 1998 from 18.7% for the six months ended March 31,
1997.
 
    OTHER GENERAL AND ADMINISTRATIVE COSTS.  Other general and administrative
costs includes rent, maintenance, travel, supplies, utilities, insurance and
professional services. Such costs increased 153.8% to $6.6 million for the six
months ended March 31, 1998 from $2.6 million for the six months ended March 31,
1997, primarily due to increased travel and other expenses related to the
integration of MSE. As a percentage of sales, other general and administrative
costs increased to 17.7% for the six months ended March 31, 1997 from 16.1% for
the six months ended March 31, 1997.
 
    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 six months ended March 31, 1998, depreciation and amortization
increased 146.2% to $1.6 million from $653,000 for the six months ended March
31, 1997. This increase was primarily attributable to the increased goodwill
recorded as a result of the MSE acquisition. As a percentage of sales,
depreciation and amortization increased slightly to 4.3% for the six months
ended March 31, 1998 from 4.0% for the six months ended March 31, 1997. The
Company expects amortization expense to increase substantially as a result of
the Cartotech acquisition.
 
    OTHER EXPENSE, NET.  Other expense, net is comprised primarily of net
interest expense. Net interest expense increased 240.0% to $884,000 for the six
months ended March 31, 1998 from $260,000 for the six months ended March 31,
1997. This increase was primarily due to increased term debt incurred in
connection with the acquisition of MSE in July 1997 and increased utilization of
the Company's lines of credit for working capital.
 
    INCOME TAX EXPENSE.  Income tax expense was $2.2 million for the six months
ended March 31, 1998 compared to $777,000 for the six months ended March 31,
1997. The Company's effective income tax rate for the six months ended March 31,
1998 was 39.4%, an increase from 38.2% for the six months ended March 31, 1997,
due to the change in the mix of state tax rates as a result of the MSE
acquisition.
 
    NET EARNINGS.  Due to the factors discussed above, net earnings increased
167.5% to $3.4 million for the six months ended March 31, 1998 from $1.3 million
for the six months ended March 31, 1997.
 
    FISCAL YEARS ENDED SEPTEMBER 30, 1997 AND 1996
 
    SALES.  The Company's sales increased $18.1 million or 80.0% to $40.8
million for fiscal 1997 from $22.7 million for fiscal 1996. This increase was
due to an increase in the number and size of customer contracts with the Company
as well as the impact of the MSE acquisition in July 1997. MSE's sales from July
2, 1997 (its date of acquisition) through September 30, 1997 were $6.8 million.
 
                                       18
<PAGE>
    SALARIES, WAGES AND RELATED BENEFITS.  Salaries, wages and related benefits
increased 88.5% to $19.8 million for fiscal 1997 from $10.5 million for fiscal
1996. As a percentage of sales, salaries, wages and related benefits increased
to 48.5% in fiscal 1997 from 46.3% in fiscal 1996, primarily due to a greater
proportion of production costs being incurred as salaries and wages as opposed
to subcontractor costs in fiscal 1997.
 
    SUBCONTRACTOR COSTS.  Subcontractor costs increased 51.3% to $5.9 million
for fiscal 1997 from $3.9 million for fiscal 1996 but decreased as a percentage
of sales to 14.5% for fiscal 1997 from 17.2% for fiscal 1996. This shift in
production expenses from subcontractor costs to salaries, wages and related
benefits resulted from the normal fluctuation between internally and externally
incurred production costs and from acquisitions. These acquisitions enabled the
Company to perform more tasks internally and reduce its use of subcontractors.
 
    OTHER GENERAL AND ADMINISTRATIVE COSTS.  Other general and administrative
costs increased 93.3% to $7.1 million for fiscal 1997 from $3.7 million for
fiscal 1996. As a percentage of sales, other general and administrative costs
increased slightly to 17.4% in fiscal 1997 from 16.3% for fiscal 1996, due
primarily to increased travel and other expenses related to the integration of
newly acquired businesses.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
50.3% to $1.8 million for fiscal 1997 from $1.2 million for fiscal 1996. This
increase was primarily attributable to the increased goodwill recorded as a
result of the MSE acquisition. As a percentage of sales, depreciation and
amortization decreased slightly to 4.4% in fiscal 1997 from 5.2% in fiscal 1996.
 
    OTHER EXPENSE, NET.  Net interest expense increased 120.0% to $772,000 for
fiscal 1997 from $351,000 for fiscal 1996. This increase was primarily due to
the increased term debt incurred in connection with the acquisition of MSE in
July 1997, as well as increased utilization of the Company's lines of credit for
working capital.
 
    INCOME TAX EXPENSE.  Income tax expense was $2.1 million in fiscal 1997
compared to $1.2 million in fiscal 1996. The effective income tax rate for 1997
was approximately 38.8%, an increase from 37.6% in 1996 due to the change in the
mix of state tax rates as a result of the MSE acquisition in the fourth quarter
of fiscal 1997.
 
    NET EARNINGS.  Due to the factors discussed above, net earnings increased
74.1% to $3.3 million for fiscal 1997 from $1.9 million for fiscal 1996.
 
    FISCAL YEARS ENDED SEPTEMBER 30, 1996 AND 1995
 
    SALES.  The Company's sales increased $9.1 million or 67.4% to $22.7 million
for fiscal 1996 from $13.5 million for fiscal 1995. This increase was primarily
due to the acquisitions of Intelligraphics and ASI Landmark in fiscal 1996 as
well as an increase in the number and size of contracts.
 
    SALARIES, WAGES AND RELATED BENEFITS.  Salaries, wages and related benefits
increased 100.1% to $10.5 million for fiscal 1996 from $5.2 million for fiscal
1995. As a percentage of sales, salaries, wages and related benefits increased
to 46.3% for fiscal 1996 from 38.8% for fiscal 1995. This increase reflects a
greater proportion of production costs being incurred as salaries, as opposed to
subcontractor costs, primarily as a result of the higher mix of internal
production costs at the two acquired businesses.
 
    SUBCONTRACTOR COSTS.  Subcontractor costs increased 20.2% to $3.9 million
for fiscal 1996 from $3.2 million for fiscal 1995 but decreased as a percentage
of sales to 17.2% for fiscal 1996 from 23.9% for fiscal 1995.
 
    OTHER GENERAL AND ADMINISTRATIVE COSTS.  Other general and administrative
costs increased 64.1% to $3.7 million for fiscal 1996 from $2.2 million for
fiscal 1995. As a percentage of sales, other general and administrative costs
decreased slightly to 16.3% for fiscal 1996 from 16.6% in fiscal 1995.
 
                                       19
<PAGE>
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
50.8% to $1.2 million for fiscal 1996 from $785,000 for fiscal 1995, due
primarily to the depreciation of newly acquired capital equipment. As a
percentage of sales, depreciation and amortization decreased slightly to 5.2% in
fiscal 1996 from 5.8% in fiscal 1995.
 
    OTHER EXPENSE, NET.  Net interest expense increased 195.0% to $351,000 for
fiscal 1996 from $119,000 for fiscal 1995, due to the increased debt incurred to
complete the Intelligraphics and ASI Landmark acquisitions.
 
    INCOME TAX EXPENSE.  Income tax expense was $1.2 million in fiscal 1996
compared to $716,000 in fiscal 1995. The effective income tax rate for 1996 was
approximately 37.6%, a slight decrease from 37.7% in 1995.
 
    NET EARNINGS.  Due to the factors discussed above, net earnings increased
61.6% to $1.9 million for fiscal 1996 from $1.2 million for fiscal 1995.
 
QUARTERLY RESULTS
 
    The Company has experienced and expects to continue to experience quarterly
variations in sales and operating income as a result of many factors, including
the effect of acquisitions, the timing of customers' budget processes, slowdowns
or acceleration of work by customers, the number of operating days in each
quarter and the impact of weather conditions on the ability of subcontractors to
obtain satisfactory aerial photography. In addition, the Company has in the past
experienced lower sales in its first fiscal quarter (ended December 31) due to
certain customers' year-end funding constraints, seasonal limitations on
obtaining aerial photography and seasonal slowdowns associated with the year-end
holidays. See "Risk Factors--Fluctuations in Quarterly Operating Results" and

(2) In July 1996 the Company acquired ASI Landmark for $2.0 million in cash.
 
(3) In July 1997 the Company acquired MSE Corporation for $12.5 million in cash

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 March
31, 1998, the Company's outstanding balance on its
 
                                       21
<PAGE>
lines of credit was $6.0 million. On June 3, 1998, the Company replaced its
existing lines of credit with a three-year, $11.0 million secured working
capital line of credit and a $10.0 million line of credit for acquisitions
(which is due in quarterly installments over a five-year period), and the
Company refinanced $16.0 million of term debt. Borrowings under the new 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 2.25%. The agent bank's prime
rate was 8.25% on June 3, 1998. The Company borrowed approximately $8.3 million
under the new acquisition line of credit to fund the cash portion of the
acquisition of Cartotech. The Company expects to pay off all outstanding
balances under the three credit facilities with proceeds from this offering. See
"Use of Proceeds."
 
    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
investment by ASI in its business, affect the Company's cash flow as projects
are signed, performed, billed and collected.
 
    Net cash provided by the Company's operating activities was $594,000,
$772,000 and $2.7 million for fiscal years 1995, 1996 and 1997, respectively.
Approximately $3.9 million in cash was used in operating activities for the
first six months of fiscal 1998, compared to $2.1 million in cash generated for
the first six months of fiscal 1997. The change in operating cash flows is
primarily attributable to normal fluctuations in the investment in
contract-related accounts. At March 31, 1998, the working capital in
contract-related accounts was equivalent to 189 days sales outstanding, up from
170 days at September 30, 1997 and 184 days at December 31, 1997. The Company
believes that this level of investment is consistent with its normal operating
range of days sales outstanding.
 
    Cash used by investing activities for fiscal years 1995, 1996 and 1997 was
$704,000, $6.4 million and $12.5 million, respectively. For the six months ended
March 31, 1998, $1.9 million was used in investing activities compared to
$339,000 for the six months ended March 31, 1997. Such investing activities
principally consisted of payments for net assets acquired in business
combinations and purchases of equipment and leasehold improvements.
 
    Cash provided by financing activities for fiscal years 1995, 1996 and 1997
was $223,000, $6.0 million and $10.3 million, respectively. For the six months
ended March 31, 1998, cash provided by financing activities was $5.3 million
compared to $458,000 in cash used for the six months ended March 31, 1997.
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 lines of credit,
proceeds from this offering and cash flow from operations are adequate to
finance its operations for at least the next 18 months.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    For the quarter ended March 31, 1998, the Company has adopted Statement of
Financial Accounting Standards No. 128 "Earnings Per Share" ("SFAS 128"). SFAS
128 requires the restatement of all prior-period earnings per share ("EPS")
data. SFAS 128 replaces the presentation of the primary EPS with a presentation
of "basic EPS" and "diluted EPS." Under SFAS 128, basic EPS excludes dilution
for common stock equivalents and is computed by dividing income available to
common shareholders by the weighted average number of common shares outstanding
for the period. Diluted EPS reflects the potential dilution that could occur if
securities or other contracts to issue common stock are exercised or converted
into
 
                                       22
<PAGE>
common stock or result in the issuance of common stock that then share in the
earnings of the entity. Under SFAS 128, the Company's diluted EPS is the same as
the income per share reported by the Company prior to the adoption of SFAS 128,
while the Company's basic EPS is greater than the income per share as previously
reported.
 
YEAR 2000 ISSUES
 
    The "Year 2000" issue concerns the potential exposures related to the
automated generation of business and financial misinformation resulting from the
application of computer programs that have been written using two digits, rather
than four, to define the applicable year. The Company and the third parties with
which it does business rely on numerous computer programs in their daily
operations. The Company has assessed its internal exposure to this issue and is
in the process of upgrading or replacing systems where necessary. The Company
does not believe that the costs to upgrade or replace such systems will be
material, and such costs will be expensed as incurred. The Company's customers
specify database designs, including date fields, and the Company's delivery of
data conforms to such specifications. Accordingly, the Company has not formally
evaluated the Year 2000 issue as it relates to the computer systems used by its
customers and potential customers.

OVERVIEW
 
    Analytical Surveys, Inc. is a leading provider of customized data conversion
and digital mapping services for the geographic information systems market. A
geographic information system ("GIS") is a high-resolution, large-scale, richly
detailed "intelligent map" that allows users to input, update, query, analyze
and display detailed information about a geographic area. Geographic information
systems are widely used by utilities, state and local governments, federal
agencies and commercial businesses to manage massive infrastructures
effectively, to improve operating efficiencies and to analyze future demand for
facilities. The Company primarily targets utilities and state and local
governments, and its current customers include the New York City Department of
the Environment, Florida Power & Light, Michigan Consolidated Gas, Southern New
England Telephone, U S WEST, British Telecom and FirstEnergy Corp.
 
    The Company believes that the market for geographic information systems is
experiencing substantial growth due to numerous factors, including: growing
awareness of the benefits of GIS technology; significant reductions in computer
hardware prices; increased capability and reliability of hardware and software;
deregulation and consolidation in the utility industry; and increased demand for
geographic information systems in growing communities. In addition, the Company
believes that GIS users are increasingly outsourcing their data conversion and
other GIS services projects to large third-party providers such as ASI. The
Company provides its customers with a single source for all data conversion
services necessary in the production of a customized GIS.
 
    In 1995, ASI embarked on its current growth strategy, which includes
consolidation of the fragmented GIS services industry. To date, the Company has
completed four strategic acquisitions that have expanded the Company's
geographical scope, capacity, customer base, product offerings, proprietary
technology and operational expertise. The Company acquired Intelligraphics
located in Wisconsin in December 1995; ASI Landmark located in North Carolina in
July 1996; MSE located in Indiana in July 1997; and Cartotech located in Texas
in June 1998.
 
    Through internal growth and acquisitions, the Company has increased its
sales from $9.1 million for fiscal 1993 to $40.8 million for fiscal 1997, an
annual compound average growth rate of 45.5%. In addition, the Company's net
income has increased from $485,000 to $3.3 million over the same period, an
annual compound average growth rate of 61.5%. As of March 31, 1998, ASI's
backlog, which represents the amount of revenue that has not been recognized on
signed contracts, was $99.0 million.
 
INDUSTRY BACKGROUND
 
    Large organizations, such as utility companies, local governments, federal
agencies and businesses, often need tools with which they can monitor complex
networks of assets and infrastructure, forecast trends, analyze present and
future demands on facilities, and manage daily operations. Central to many of
these processes are the availability and integration of accurate geo-referenced
information.
 
    Historically, geo-referenced information, such as the location of utility
facilities and infrastructure, tax data, property assessments and zoning
restrictions, has been available only in paper-based form, such as maps, aerial
photographs and property records, or in tabular databases. Geo-referenced
information in these forms is difficult to integrate into useful information
systems and offers few opportunities to leverage information into additional
uses in a timely and effective manner. The advent of more powerful, reliable and
less expensive computer hardware and software, greater standardization of
operating systems such as Windows NT, and more cost-effective means of
delivering a GIS, such as CD-ROM or electronic distributions via the Internet,
have made geographic information systems an affordable and widely-utilized tool
in many organizations. As a result, more organizations are implementing
geographic information systems in order to manage previously overwhelming
amounts of information and are expanding both the access to and applications for
geographic information systems.

    GEOGRAPHIC INFORMATION SYSTEMS
 
    A geographic information system is a high-resolution, large-scale (E.G., one
inch = 100 feet), richly detailed "intelligent map" that allows users to input,
update, query, analyze and display information about a geographic area. A GIS
integrates database operations, such as query and statistical analyses, with the
unique visualization and geographic analyses offered by paper maps. The
capabilities of a GIS make it a valuable tool for a wide range of organizations
for complex analysis and planning.
 
    A GIS is produced by converting high-resolution aerial photography or paper
maps into a digital form to create a digital base map. Once a digital base map
has been created, additional geo-referenced data (E.G., water and sewer lines,
power lines and property boundaries) are converted into digital form and added
as additional layers of information onto the base map. The map can then be
linked to existing or newly created tabular databases, such as property records
and billing and usage history. The resulting GIS is used to perform the specific
analyses and functions required by users. New or changed data can then be added
easily, allowing users to maintain records that are more accurate, detailed and
current than paper maps, and can be accessed simultaneously by multiple users
within an organization.
 
    USERS OF GEOGRAPHIC INFORMATION SYSTEMS
 
    Geographic information systems are most widely used by utilities, state and
local governments, federal agencies and commercial businesses to manage massive
infrastructures more effectively, to improve operating efficiencies and to
analyze future demand for facilities. Typical customers and applications for
geographic information systems are illustrated below.

    THE GIS MARKET
 
    Frost & Sullivan, an industry research firm, estimates that the global GIS
market will grow from $4.5 billion in 1997 to $8.1 billion by 2002. Frost &
Sullivan identifies five segments within the GIS market: software for personal
computers; software for work stations; software for mainframes; data; and
services
 
                                       25
<PAGE>
(which includes consulting, systems integration, database design, data
collection and data conversion). The Company competes primarily in the data
conversion and collection segments of the GIS services industry. Frost &
Sullivan estimates that the GIS services market, which represents approximately
70% of the global GIS market, will grow from $3.2 billion in 1997 to $5.5
billion in 2002.
 
    The GIS services business is very competitive and highly fragmented.
Participants in the industry include small regional firms, large independent
firms, large companies with GIS services divisions, in-house operations and
international low-cost providers of data conversion services. The Company
believes that many of the businesses in the GIS services industry do not have
adequate access to capital for expansion, lack the capacity to complete large,
long-term projects and do not have the technical expertise or experience that
customers increasingly require of their GIS services vendors. As a result, the
Company believes that the industry is poised for consolidation.
 
    FACTORS DRIVING MARKET GROWTH
 
    Several factors are driving the growth of the GIS services market:
 
    - INCREASED AWARENESS OF THE BENEFITS OF GIS. As GIS technology is
      implemented and becomes an integral part of the planning and
      decision-making processes throughout organizations, such as utilities and
      governments, an increased awareness of the benefits of geographic
      information systems is driving greater demand.
 
    - ADVANCES IN TECHNOLOGY. Significant reductions in computer hardware and
      software prices, as well as increased processing power and reliability of
      information systems, have made geographic information systems more
      technologically feasible and economically viable for organizations to
      implement and maintain. As a result, GIS technology is available for more
      users within organizations, thereby increasing access and applications for
      geographic information systems.
 
    - DEREGULATION AND CONSOLIDATION IN THE UTILITY INDUSTRY. Increased
      competition in the utility industry, brought about by deregulation and
      consolidation, has fueled demand for geographic information systems as
      utilities seek the benefits of geographic information systems in order to
      market more effectively, increase operating efficiencies and manage larger
      infrastructures.
 
    - NEEDS OF GROWING COMMUNITIES. Rapid population growth has increased the
      requirements of certain state and local governments for geographic
      information systems to assist in building and managing infrastructures,
      including resources such as roads, utilities and fire departments.
 
    - TREND TOWARDS OUTSOURCING. The Company believes that GIS users are
      increasingly outsourcing their data conversion and collection projects,
      recognizing the numerous benefits of leveraging the expertise and capacity
      of third-party vendors. In addition, outsourcing allows customers to
      continue to focus on their core businesses and avoid the significant
      investments in personnel and infrastructure required to implement and
      maintain a GIS.
 
ANALYTICAL SURVEYS, INC.
 
    The Company serves as a single-source provider for all data conversion and
collection services necessary to create a customized GIS. Through internal
development and strategic acquisitions, the Company has developed significant
resources and capacity to perform the wide range of data conversion and
collection tasks necessary in the successful completion of large, complex
projects for a wide range of industries. The Company has also developed and
acquired industry-leading expertise and proprietary technology essential to
accurately and timely satisfy the unique requirements of each GIS project. In
addition, ASI's completion of four strategic acquisitions since 1995 has
established it as one of the industry's leading consolidators.
 
                                       26

STRATEGY
 
    The Company's objective is to maintain and enhance its leadership position
in the data conversion and digital mapping industry. This objective is reflected
in the Company's strategy:
 
    - EXPAND BUSINESS IN EXISTING MARKETS. The Company believes that there is
      significant potential within its existing customer base for expanded
      services and products and intends to add to the breadth of services it
      offers to such customers. The Company also intends to capitalize on the
      increasing number of GIS users in its core markets of utilities and state
      and local governments by marketing to new customers in these markets and
      increasing capacity in order to meet the demands of an expanded customer
      base.
 
    - CONSOLIDATE INDUSTRY EXPERTISE AND "BEST PRACTICES" THROUGH STRATEGIC
      ACQUISITIONS. In 1995, ASI embarked on a strategy to acquire companies
      with demonstrated records of performance, proven operating methods, solid
      management teams and complementary technologies and customer bases. To
      date, the Company has completed four strategic acquisitions that have
      expanded the Company's geographical scope, capacity, customer base,
      product offerings, proprietary technology and operational expertise. By
      retaining the core management teams at these acquired companies, the
      Company believes that it is able to take advantage of the "best practices"
      of each acquired company. The Company intends to continue consolidating
      the highly fragmented GIS services industry by targeting similar
      businesses for acquisition. See "--Recent Acquisitions" and "Risk
      Factors--Risks Associated with Acquisition Strategy."
 
    - CONTINUE TO MAINTAIN AND DEVELOP TECHNOLOGICAL AND OPERATIONAL
      LEADERSHIP. The Company believes that its past success has been largely
      due to its technological expertise and operating procedures. The Company
      has developed and acquired proprietary software and procedures that
      automate portions of otherwise labor-intensive data conversion processes,
      enabling the Company to provide cost-effective and high-quality services
      on a timely basis. The Company intends to continue its efforts to develop
      new technology and to improve its existing technology and procedures,
      thereby enhancing its ability to expand into additional markets and
      further improve its production capacity and productivity. See "--Research
      and Development."
 
    - EXPAND INTO INTERNATIONAL MARKETS. In fiscal 1997 and for the six months
      ended March 31, 1998, revenues from international sales represented
      approximately 6.3% and 8.3% of the Company's total revenues, respectively.
      The Company intends to increase its share of the international GIS
      services market by targeting international GIS users within its core
      markets. The Company believes that alliances with local businesses or
      individuals may be important to successful entry into certain
      international markets. The Company intends to continue to seek out such
      relationships and to continue to market directly to international GIS
      users. See "--Sales and Marketing."

    DESIGN OF A GIS PROJECT
 
    Data conversion and collection services comprise an important part of the
process of developing a geographic information system. The development of a GIS
typically involves multiple vendors, each of whom may participate in one or more
portions of the overall project. Such vendors, which include consultants,
hardware and software vendors and data conversion and collection providers, are
generally evaluated on the basis of experience, expertise, reputation,
production capacity and price. The typical phases of a GIS project are:
planning/bidding; contract award; data collection; data conversion; and
maintenance and updating.

    A description of the tasks performed during each phase of a typical project
is set forth below. These tasks, from planning/bidding through data conversion,
generally take between one to four years to complete. Services provided by the
Company are highlighted in italicized boldface type.

    SPECIALIZED SERVICES OF ASI
 
    The Company offers a full range of services to create the digital base maps
and databases of related geo-referenced information used in geographic
information systems.
 
    DIGITAL LAND BASE MAPS.  ASI uses specialized computers and internally
developed proprietary software to create digital land base maps from paper maps,
aerial photographs, land surveys and legal descriptions. The base maps are
created using one of three technologies, depending on the needs of the customer:
photogrammetric mapping, digital orthophotography or cadastral mapping.
 
    - PHOTOGRAMMETRIC MAPPING. Photogrammetric mapping produces a digital land
      base map using data that is extracted from aerial photographs. The process
      uses an analytical stereoplotter (a three-dimensional viewing and data
      recording device), specialized computer equipment and proprietary software
      and operating procedures to draw, with lines, a highly precise map of
      visible ground features. Photogrammetric mapping may include contour and
      elevation information.
 
    - DIGITAL ORTHOPHOTOGRAPHY. Digital orthophotography is used to create
      richly detailed digital maps that have the appearance of, and are based
      on, aerial photographs. Aerial photographs are scanned
 
                                       28
<PAGE>
      into a computer, and the resulting image is corrected (orthorectified) to
      delete distortions in order to produce a highly precise map. Vector lines
      can be superimposed onto the map to enable users to determine the precise
      location of any particular feature or to measure distances from one
      feature to another. Digital orthophotographs also can be used as base maps
      for the layering of additional geo-referenced data.
 
    - CADASTRAL MAPPING. Cadastral maps illustrate property lines and are
      prepared by digitizing existing paper maps or converting the legal
      property descriptions into map coordinates.
 
    OTHER GEO-REFERENCED INFORMATION.  Once the base map is produced, links to
tabular databases are created, and other geo-referenced data, such as buildings,
telephone poles and zoning restrictions, are collected, verified, converted into
digital format and added to the base map to create a GIS. The Company provides
an experienced field inventory staff to collect and verify information and uses
computerized and manual techniques to verify and digitize data from paper
sources. Once a GIS is completed, users can view the base map and any or all of
the layers of data on a computer screen and can retrieve selected data
concerning any desired location appearing on the screen or all data matching one
or more variables. A GIS map with layered geo-referenced information is
illustrated below.
 
This graphic is titled "GIS Data Layers" and features a black and white
graphical representation of multiple layers of GIS data. Down the center of the
page are seven stacked map images. In a column running down the left side of the
page under the title "Data Layer," each of the seven images to the right is
identified in the following order, from top to bottom: telephone, electric,
water, sewer, gas, deeds research and base map. An arrow points from the
verbiage in the left column to the image it identifies in the center of the
page. On the right side of the page, under the title "Uses," a sample usage for
each data layer is listed. Additionally, each usage includes a representative
icon. An arrow points from each of the data layers in the center to the
corresponding usage on the right. The usages are identified in the following
order: billing records (folder icon), load analysis (computer hard-drive icon)
hydrology modeling (water drop icon), maintenance records (computer diskette
icon), usage records (stacked paper icon) and tax assessment (open folder icon).

RECENT ACQUISITIONS
 
    In 1995, the Company embarked on its current growth strategy, including
consolidation of the fragmented GIS services industry. The Company acquired
substantially all of the assets of Intelligraphics, based in Wisconsin, in
December 1995. Intelligraphics, with over 200 employees, significantly expanded
the Company's capacity to perform large projects, added utility industry
expertise and established ASI's presence in the midwestern United States. The
acquisition contributed over 25 new customers and $12.3 million in backlog to
the Company.
 
    In July 1996, the Company expanded its services to state and local
governments by acquiring substantially all of the assets of ASI Landmark. Based
in North Carolina, ASI Landmark's primary business is land base and cadastral
mapping. Prior to this acquisition, ASI had utilized outside subcontractors for
certain of these services. ASI Landmark also provided the Company with
additional capacity for photogrammetry and a presence in the eastern and
southeastern United States. The acquisition contributed approximately 20 new
customers, $9.1 million in backlog and 105 employees to the Company.
 
    The Company acquired MSE in July 1997. The acquisition of Indiana-based MSE
gave the Company greater capacity to serve the utility market and further
enhanced ASI's presence in the midwestern United States. In addition, the
acquisition of MSE contributed over 200 new customers and $43.0 million of
backlog to the Company. Over 325 employees joined the ASI workforce as a result
of the MSE acquisition, including the Company's current Chief Operations Officer
and Chief Administrative Officer.
 
    The Company acquired Texas-based Cartotech in June 1998. The Cartotech
acquisition extended ASI's presence in the utility market, enhanced the
Company's field inventory operations and provided the Company with a strong
presence in the southwestern United States. The Cartotech acquisition
contributed over 50 new customers and 270 employees to the Company. One of
Cartotech's customers, FirstEnergy Corp. (formerly known as Ohio Edison),
accounted for approximately 46.0% of Cartotech's revenues in 1997.
 
    With all of its acquisitions to date, the Company has retained the core
management teams and most employees in order to capitalize on their
understanding of their respective markets and to provide continuity with
existing customer relationships. As a result, the acquired businesses continue
to operate somewhat independently while the Company has taken steps to
assimilate the businesses on a gradual basis. The Company believes that this
approach avoids disrupting existing customer relationships, promotes initiative
and responsibility by such management and personnel and avoids the disruption
that can accompany rapid assimilation. This approach also enables the Company to
promote use of the "best practices" of the acquired businesses throughout the
Company in such areas as bid preparation, production processes and utilization
of proprietary software.
 
    Acquisitions involve a number of special risks, including, but not limited
to, potential adverse short-term effects on the Company's operating results,
diversion of management's attention, the loss of key personnel, risks associated
with the assimilation of the operations and personnel of the acquired companies,
unanticipated business problems or legal liabilities and amortization of
acquired intangible assets. In addition, when the Company acquires another
business, it assumes the obligation to complete the acquired company's contracts
that are in process. The Company's results of operations following any
acquisition will depend, in part, on the ability of the Company to profitably
complete such contracts, which could be adversely affected by the acquired
company's underestimation of the cost or amount of work required to complete the
project as well as additional costs necessary to correct problems associated
with the acquired company's prior performance. There is no assurance that the
Company will be able to integrate Cartotech or other acquired businesses into
the Company without substantial costs, delays or other operational or functional
difficulties, or to obtain the synergies expected from such acquisitions. Some
or all of these risks could have a material adverse effect on the Company. See
"Risk Factors--Risks Associated with Acquisition Strategy" and "Risk Factors--
Ability to Manage Growth."

    The Company derives its revenues primarily from two core markets, utilities
and state and local governments, and also serves federal agencies and commercial
businesses. From time to time, the revenues earned on a specific contract may
exceed 10% of total Company revenues earned in a fiscal year. The only customer
that accounted for more than 10% of the Company's revenues in fiscal 1996 was
Southern New England Telephone, which accounted for approximately 10% of
revenues in that year. No customer accounted for more than 10% of the Company's
revenues in fiscal 1997. See "Risk Factors--Dependence on Certain Customer
Markets."

SALES AND MARKETING
 
    The Company markets its products and services in its domestic and
international markets primarily through an internal sales force. The Company
augments its direct sales efforts by maintaining memberships in professional and
trade associations and by actively participating in industry conferences.
 
    A significant portion of the Company's sales is the result of referrals
derived, either directly or indirectly, from consultants in the GIS industry.
The Company believes that its continued success in the GIS services market is
dependent, in part, on its ability to maintain current relationships and to
cultivate additional relationships with other leading consultants. Such
consultants could independently acquire a GIS data collection or data conversion
business or businesses or form other relationships with the Company's
competitors. There can be no assurance that relationships with GIS consultants
will continue to be a source of business for the Company. See "Risk
Factors--Dependence on Business Alliances."
 
                                       31
<PAGE>
    The Company believes that alliances with local businesses or individuals may
be important to successful entry into certain international markets and intends
to continue to seek out such relationships and to market directly to
international customers.
 
    The Company's sales cycle is generally lengthy, as customers normally take
several months to go through the bidding/planning and award phases of a GIS
project. Once awarded, it generally takes 30 to 60 days until the final contract
is signed. Most contracts take from six to 48 months to complete.
 
SUBCONTRACTORS
 
    ASI employs certain selected subcontractors for tasks outside its expertise,
such as aerial photography and ground survey. The Company also uses
subcontractors when necessary to expand capacity, meet deadlines, reduce
production costs, manage work load and encourage businesses owned by women and
minorities. The inability to obtain the services of such subcontractors when
needed or at all could have a material adverse effect on the Company. In May
1998, the Company acquired Interra Technologies, a 280-employee India-based
company, for $430,000. Interra Technologies had been a provider of subcontractor
services to the Company. See "Risk Factors--Dependence on Subcontractors," "Risk
Factors-- Dependence on Offshore Operations" and "Business--Personnel."
 
RESEARCH AND DEVELOPMENT
 
    The Company believes that its past success has been largely due to its
technological expertise and operating procedures. The Company has developed and
acquired proprietary software and procedures that automate portions of otherwise
labor-intensive data conversion processes, enabling the Company to provide
cost-effective and high-quality services on a timely basis. The Company intends
to continue its efforts to develop new technology and to improve its existing
technology and procedures, thereby enhancing its ability to expand into
additional markets and further improve its production capacity and productivity.
 
    The Company engages in significant 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 fiscal 1997 and for the six months ended March 31, 1998,
the Company expended $275,000 and $120,000, respectively, on such independent
research and development activities.
 
    The Company employs six full-time employees for research and development
activities in its Advanced Technology Division in Colorado Springs, Colorado. In
addition, the Company employs two individuals in Indianapolis, Indiana to
continue the development of certain of its proprietary software. Approximately
50 additional employees are substantially engaged in research and development
efforts as an integral part of the Company's services to its customers. See
"Risk Factors--Reliance on Technology; Limited Protection of Proprietary
Rights."
 
COMPETITION
 
    The GIS services business is very competitive and highly fragmented. The
Company's competitors include small regional firms, independent firms, large
companies with GIS services divisions, customer in-house operations and
international low-cost providers of data conversion services. Additionally, as
the GIS services industry evolves, additional competitors with greater resources
than the Company may enter the industry. Several large companies with
substantial financial resources are in the process of launching satellites with
imagery technology that provides much more detailed photographs than have been
available
 
                                       32
<PAGE>
with such technology in the past. Although current commercially available
satellite imagery does not provide the degree of-resolution required by most of
the Company's customers, if such technology becomes commercially available,
satellite companies may attempt to enter the GIS services business or could form
strategic alliances with the Company's competitors, and thereby could pose a
substantial competitive threat to the Company. In addition, other improvements
in technology could provide competitors or customers with readily available
tools to perform the services provided by the Company and lower the cost of
entry into the GIS services industry. A number of the Company's competitors or
potential competitors have capabilities and resources greater than those of the
Company.
 
    ASI seeks to compete on the basis of the quality of its products and the
accuracy, responsiveness and efficiency with which it can provide services to
customers. The Company uses its internally-developed proprietary production
software as well as commercially available software to automate much of the
otherwise labor-intensive GIS production process. The Company believes that its
automated approach enables it to achieve more consistent quality and greater
efficiencies than it could if it used more manually-intensive methods. The
Company also believes that the retention of highly qualified managers and
executive officers is critical to its ability to compete in the GIS data
conversion industry. See "Risk Factors--Competition" and "Dependence on Key
Personnel."
 
CUSTOMER CONTRACTS
 
    Virtually all of the Company's revenue is earned under long-term,
fixed-price contracts. The Company's contractual obligations typically include
several large projects that will extend over one to four years. The Company's
ability to estimate its costs accurately when negotiating the overall price of a
project is critical to ensuring the profitability of such project. The Company
must also control the costs of performance under such fixed-price contracts. As
the Company increases its marketing efforts to obtain larger projects, the needs
to estimate costs accurately and to control costs of performance become more
important. Schedule delays resulting from a customer's lack of available funding
or schedule compressions required by customers may place additional strains on
management to hire and train the personnel required for project completion. The
Company's contracts with its customers are generally terminable by the customer
on relatively short notice, and customers may request that the Company slow down
or scale back the scope of a project in order to satisfy the customer's budget
or cash flow requirements. In addition, the Company could experience material
contract terminations or slowdowns. Long-term, fixed-price contracts for larger
projects generally increase the Company's risk due to inflation. See "Risk
Factors-- Risks Associated with Terms of Customer Contracts."
 
PERSONNEL
 
    As of June 26, 1998, ASI had approximately 1,745 employees, virtually all of
whom are full-time. ASI does not have a collective bargaining agreement with any
of its employees and generally considers relations with its employees to be
good.
 
    The Company's business is labor intensive and requires specially trained
employees. Each new data conversion technician receives on-the-job training and
is generally considered to be fully trained after approximately four to six
months. Management constantly tracks performance under existing contracts and
projects staffing needs for continuing and new contracts. The increased capacity
from its four recent acquisitions has given the Company added flexibility to
allocate its personnel resources to meet customer demand. The Company has kept
the management teams from its recent acquisitions essentially intact and has
retained most of the employees.
 
    In order to support additional growth, if any, the Company must increase
production capacity by the addition of more employees. There can be no assurance
that the Company will be able to continue to hire, train and retain sufficient
numbers of qualified employees. A significant portion of the Company's costs
 
                                       33
<PAGE>
consists of wages to hourly workers. An increase in hourly wages, costs of
employee benefits or employment taxes could have a material adverse effect on
the Company. Although the Company believes that its employee turnover rate is at
an acceptable level, turnover could increase for any of several reasons,
including the disruption that is sometimes associated with the acquisition of
businesses and increased competition for labor in any geographic area where the
Company operates. A higher turnover rate among the Company's employees would
increase the Company's recruiting and training costs, could affect the Company's
ability to perform services and earn revenues on a timely basis, and could
decrease operating efficiencies and productivity. See "Risk Factors--Dependence
on Internal Labor Force."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Sales of substantial amounts of Common Stock in the public market after this
offering could adversely affect the market price of the Common Stock. Upon
completion of this offering, there will be 8,437,327 shares of Common Stock
outstanding. Of these shares, 7,196,116 will be freely tradeable without
restriction. On June 27, 1999 and June 27, 2000, an aggregate of 238,743 and
115,424 shares, respectively, will become eligible for sale in the public market
upon the expiration of certain lock-up agreements entered into in connection
with the Cartotech acquisition. In addition, the holders of an aggregate of
887,044 shares of Common Stock have agreed, pursuant to certain lock-up
agreements entered into in connection with this offering, not to offer or sell
any shares of Common Stock of the Company for a period of 90 days following the
date of this Prospectus without the prior written consent of NationsBanc
Montgomery Securities LLC. Upon the expiration of these lock-up agreements with
NationsBanc Montgomery Securities LLC and subject in each case to provisions of
Rule 144 under the Securities Act, (i) 262,044 of these shares will be eligible
for sale in the public market, and (ii) the remaining 625,000 shares will be
eligible for sale on July 2, 1999 upon the expiration of a lock-up agreement
entered into in connection with the MSE acquisition. Holders of approximately
863,743 shares of "Restricted Securities " (as such term is defined in the
Securities Act) are entitled to certain incidental and demand registration
rights with respect to registration of such shares for offer or sale to the
public. To the extent that such registration rights are exercised, the number of
shares freely tradeable in the public market will increase, which could
adversely affect the market price of the Common Stock. See "Principal and
Selling Shareholders" and "Shares Eligible for Future Sale."
 
    The Company has registered for issuance or resale the 2,878,000 shares of
Common Stock reserved for issuance under the Company's stock option plans. As of
May 31, 1998, options to purchase 1,744,000 shares had been granted and were
outstanding under the Company's stock option plans, of which options to purchase
513,000 shares were currently exercisable. Options to purchase the remaining
1,231,000 shares become exercisable at varying times thereafter.
 
    In general, under Rule 144 as currently in effect, a shareholder who has
beneficially owned for at least one year shares privately acquired directly or
indirectly from the Company or from an affiliate of the Company, and persons who
are affiliates of the Company who have acquired the shares in registered
transactions, will be entitled to sell within any three-month period a number of
shares that does not exceed the greater of: (i) 1% of the outstanding shares of
the Common Stock (approximately 84,373 shares immediately after consummation of
the offering); or (ii) the average weekly trading volume in the Common Stock
during the four calendar weeks preceding such sale. Sales under Rule 144 are
also subject to certain requirements relating to the manner and notice of sale
and the availability of current public information about the Company.
 
    The Company has agreed with the Underwriters not to offer, sell or otherwise
dispose of Common Stock or securities convertible into or exercisable or
exchangeable for such shares for a period of 90 days after the offering without
the prior written consent of NationsBanc Montgomery Securities LLC, except that
the Company may grant options or issue stock upon exercise of new or outstanding
options pursuant to its stock option plans without such consent.

                                  UNDERWRITING
 
    NationsBanc Montgomery Securities LLC and Dain Rauscher Wessels, a division
of Dain Rauscher Incorporated ("Dain Rauscher Wessels"), (collectively, the
"Underwriters") have severally agreed, subject to the terms and conditions
contained in the Underwriting Agreement (the "Underwriting Agreement") by and
among the Company, the Selling Shareholders and the Underwriters, to purchase
from the Company and the Selling Shareholders the number of shares of Common
Stock indicated below opposite their respective names, at the public offering
price less the underwriting discount set forth on the cover page of this
Prospectus. The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters are committed to purchase all of such shares of Common Stock, if
any are purchased.

    The Underwriters have advised the Company and the Selling Shareholders that
the Underwriters propose initially to offer the shares of Common Stock to the
public on the terms set forth on the cover page of this Prospectus. The
Underwriters may allow to selected dealers a concession of not more than $
per share, and the Underwriters may allow, and such dealers may reallow, a
concession of not more than $      per share to certain other dealers. After
this offering, the offering price and other selling terms may be changed by the
Underwriters. The Common Stock is offered subject to receipt and acceptance by
the Underwriters, and to certain other conditions, including the right to reject
orders in whole or in part.
 
    The Company and the Selling Shareholders have granted the Underwriters an
option exercisable during the 30-day period after the date of this Prospectus to
purchase up to a maximum of 337,500 additional shares of Common Stock to cover
over-allotments, if any, at the same price per share as the initial 2,250,000
shares to be purchased by the Underwriters. To the extent that the Underwriters
exercise this overallotment option, the Underwriters will be committed, subject
to certain conditions, to purchase such additional shares in approximately the
same proportion as set forth in the above table.
 
    The Company, the Selling Shareholders and the Company's directors and
executive officers have agreed that, until 90 days after the date of this
Prospectus, they will not, without the prior written consent of NationsBanc
Montgomery Securities LLC, offer, sell or otherwise dispose of any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for any shares of Common Stock, except that the Company, without such consent,
may grant options or issue stock upon exercise of new or outstanding options
pursuant to the Company's stock option plans.
 
    The Underwriting Agreement provides that the Company and the Selling
Shareholders will indemnify the Underwriters against certain liabilities,
including civil liabilities under the Securities Act, or will contribute to
payments the Underwriters may be required to make in respect thereof.
 
    Until the distribution of the Common Stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the Underwriters and
certain selling group members to bid for and purchase the Common Stock. As an
exception to these rules, the Underwriters are permitted to engage in certain
transactions that stabilize the price of the Common Stock. Such transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the Common Stock. If the Underwriters create a short position in
the Common Stock in connection with the offering, i.e., if they sell
 
                                       40
<PAGE>
more shares of Common Stock than are set forth on the cover page of this
Prospectus, the Underwriters may reduce that short position by purchasing Common
Stock in the open market. The Underwriters may also elect to reduce any short
position by exercising all or part of the over-allotment option described above.
The Underwriters may also impose a penalty bid on certain Underwriters and
selling group members. This means that if the Underwriters purchase shares of
Common Stock in the open market to reduce the Underwriters' short position or to
stabilize the price of the Common Stock, they may reclaim the amount of the
selling concession from the Underwriters and selling group members who sold
those shares as part of the offering.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it
discourages resales of the security. Neither the Company nor any of the
Underwriters makes any representation or predictions as to the direction or
magnitude of any effect that the transactions described above may have on the
price of the Common Stock. In addition, neither the Company nor any of the
Underwriters makes any representation that the Underwriters will engage in such
transactions or that such transactions, once commenced, will not be discontinued
without notice.
 
    The Underwriters have advised the Company that the Underwriters and dealers
may engage in passive market making transactions in the Common Stock in
accordance with rules promulgated by the Commission. In general, a passive
market maker may not bid for or purchase the Common Stock at a price that
exceeds the highest independent bid. In addition, the net daily purchases made
by any passive market maker generally may not exceed 30% of its average daily
trading volume in the Common Stock during a specified two-month prior period or
200 shares, whichever is greater. A passive market maker must identify passive
market making bids as such on the Nasdaq electronic inter-dealer reporting
system. Passive market making may have the effect of stabilizing or maintaining
the market price of the Common Stock at a level above that which might otherwise
prevail in the open market. Underwriters and dealers are not required to engage
in passive market making and may discontinue such activities at any time.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Analytical Surveys, Inc.:
 
    We have audited the accompanying consolidated balance sheets of Analytical
Surveys, Inc. and subsidiaries as of September 30, 1996 and 1997, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for each of the years in the three-year period ended September 30, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Analytical
Surveys, Inc. and subsidiaries as of September 30, 1996 and 1997, and the
results of their operations and their cash flows for each of the years in the
three-year period ended September 30, 1997 in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                          SEPTEMBER 30, 1996 AND 1997
 
                         AND MARCH 31, 1998 (UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    (A) BUSINESS AND BASIS OF FINANCIAL STATEMENT PRESENTATION
 
    Analytical Surveys, Inc. (ASI or the Company) is a Colorado corporation
formed in 1981. ASI's primary business is the production of precision
computerized maps and information files used in Geographic Information Systems
(GIS). Federal, state and local government agencies and commercial companies use
GIS to manage information relating to utilities, natural resources, streets,
land use and property taxation.
 
    The consolidated financial statements include the accounts of the Company
and its wholly and majority owned subsidiaries. All significant intercompany
balances and transactions have been eliminated in consolidation.
 
    Unaudited interim financial information as of March 31, 1998 and for the six
months ended March 31, 1997 and 1998 has been prepared by the Company on a basis
consistent with the annual financial statements and, in the opinion of
management, includes all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of such information. The results
of operations for the six months ended March 31, 1998 are not necessarily
indicative of the results to be expected for the entire fiscal year.
 
    The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
    (B) EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
    Equipment and leasehold improvements are recorded at cost. Depreciation and
amortization are provided using the straight-line method over the following
estimated useful lives:
 
<TABLE>
<S>                                                             <C>
                                                                3 to 10
Equipment.....................................................  years
                                                                5 to 10
Furniture and fixtures........................................  years
                                                                5 to 10
Leasehold improvements........................................  years
</TABLE>
 
    Maintenance, repairs and renewals which do not add to the value of an asset
or extend its useful life are charged to expense as incurred.
 
    (C) REVENUE RECOGNITION
 
    The Company recognizes revenue using percentage of completion accounting
based on the cost-to-cost method, whereby the percentage complete is based on
costs incurred in relation to total estimated costs. Costs associated with
obtaining contracts are expensed as incurred. The Company does not combine
contracts for purposes of recognizing revenue and, generally, does not segment
contracts.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                          SEPTEMBER 30, 1996 AND 1997
 
                         AND MARCH 31, 1998 (UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Revenue in excess of billings represents revenue related to services
completed but not billed. The Company bills customers based upon the terms
included in the contract, which is generally upon delivery. When billed, such
amounts are recorded as accounts receivable. Billings in excess of revenue
represent billings in advance of services performed.
 
    The Company recognizes losses on contracts in the period such losses are
determined. The Company does not believe warranty obligations on completed
contracts are significant.
 
    (D) GOODWILL
 
    Goodwill represents the excess of the purchase price over net assets
acquired in business combinations and is being amortized over a fifteen-year
period using the straight-line method.
 
    (E) INCOME TAXES
 
    The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS 109).
SFAS 109 requires the use of the asset and liability method of accounting for
income taxes. Under the asset and liability method of SFAS 109, deferred tax
assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases. Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered or settled. Under SFAS 109, the effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date.
 
    (F) STOCK-BASED COMPENSATION
 
    The Company accounts for its stock-based employee compensation plans using
the intrinsic value based method prescribed by Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, and related
interpretations (APB 25). The Company has provided pro forma disclosures of net
income as if the fair value based method of accounting for the plans, as
prescribed by Statement of Financial Accounting Standards No. 123, Accounting
for Stock-Based Compensation (SFAS 123), had been applied. Pro forma disclosures
include the effects of employee stock options granted during the years ended
September 30, 1997 and 1996.
 
    (G) IMPAIRMENT OF LONG-LIVED ASSETS
 
    Effective October 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to Be Disposed Of (SFAS 121) which requires that
long-lived assets and certain identifiable intangibles held and used by an
entity be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying value of an asset may not be recoverable. An
impairment loss is recognized when estimated undiscounted future cash flows
expected to be generated by an asset are less than its carrying value.
Measurement of the impairment loss is based on the fair value of the asset,
which is generally determined using valuation

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                          SEPTEMBER 30, 1996 AND 1997
 
                         AND MARCH 31, 1998 (UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
techniques such as the discounted present value of expected future cash flows or
independent appraisal. The adoption of SFAS 121 on October 1, 1996 had no effect
on the consolidated financial statements of the Company.
 
    (H) RESEARCH AND DEVELOPMENT COSTS
 
    The Company expenses research and development costs as they are incurred.
Research and development costs, which are included in general and administrative
expenses in the consolidated statements of operations, totaled $274,905,
$283,872 and $347,321 for the years ended September 30, 1997, 1996 and 1995,
respectively.
 
    (I) EARNINGS PER SHARE
 
    Earnings per share has been presented in accordance with the provisions of
Statement of Financial Accounting Standards No. 128 "Earnings Per Share" (SFAS
128). SFAS 128 requires the presentation of basic earnings per share (EPS) and
diluted EPS. Basic EPS excludes dilution for potential common stock and is
computed by dividing earnings available to common shareholders by the weighted
average number of common shares outstanding for the period. Diluted EPS reflects
the potential dilution that could occur if securities or other contracts to
issue common stock were exercised or converted into common stock or resulted in
the issuance of common stock. The Company's diluted EPS for prior periods was
the same as primary EPS previously reported while the Company's basic EPS is
greater than the primary EPS previously reported.
 
    (J) FINANCIAL INSTRUMENTS
 
    The carrying amounts of the Company's financial instruments at September 30,
1997 and 1996 approximate estimated fair values. The fair value of a financial
instrument is the amount at which the instrument could be exchanged in a current
transaction between willing parties. The carrying amounts of cash and cash
equivalents, receivables, accounts payable and accrued liabilities approximate
fair value due to the short maturity of these instruments. The carrying amounts
of debt approximate fair value due to the variable nature of the interest rates
of these instruments.
 
    (K) RECLASSIFICATIONS
 
    Certain prior year amounts have been reclassified to conform to the 1997
presentation.
 
(2) BUSINESS COMBINATIONS
 
    In July 1997, the Company acquired all of the issued and outstanding common
stock of MSE Corporation for cash of $12,500,000 and 925,000 shares of
restricted common stock valued at $7,313,000, for total consideration of
$19,813,000.
 
    In July 1996, the Company, through its wholly owned subsidiary, ASI
Landmark, Inc., acquired substantially all of the assets and assumed certain
liabilities of Westinghouse Landmark GIS, Inc. which

provides photogrammetric mapping and data conversion services to the municipal
and county markets for cash of $1,992,598.
 
    In December 1995, the Company acquired substantially all of the assets and
assumed certain liabilities of Intelligraphics, Inc. which provides data
conversion services primarily to the utilities market, for $3,548,019 cash and
345,000 shares of restricted common stock valued at $891,250, for total
consideration of $4,439,269.
 
    All of the acquisitions were accounted for using the purchase method of
accounting and, accordingly, the accompanying consolidated financial statements
include the results of operations of the acquired businesses since the date of
acquisition. The aggregate purchase prices of the acquisitions were allocated
based on fair values as follows (amounts in thousands):

(4) DEBT
 
    The Company had two revolving lines-of-credit with banks which provided for
total borrowings of $4,850,000, expiring in February 1999, and bore interest at
0.25% over the prime rate (8.75% at September 30, 1997) and the prime rate
(8.50% at September 30, 1997). The lines-of-credit were collateralized by
substantially all of the assets of the Company. Borrowings of $500,000,
$1,473,000 and $5,990,000 were outstanding under the lines-of-credit as of
September 30, 1996 and 1997 and March 31, 1998, respectively.
 
    In February 1997 the Company entered into an additional $1,000,000 revolving
line-of-credit with a bank bearing interest at 8.25%. The line-of-credit is
collateralized by all equipment and general intangibles and expires February
2003. No borrowings were outstanding under the line-of-credit as of September
30, 1997 or March 31, 1998.
 
    On June 3, 1998, the Company replaced its existing lines-of-credit with a
three-year $11,000,000 secured line of credit and a $10,000,000 line of credit
for acquisitions (which is due in quarterly installments over a five-year
period), and the Company refinanced $16,000,000 of term debt. Borrowings under
the new credit facilities bear interest at either the prime rate or LIBOR plus
1.25% to 2.25%.

totaled $437,000, $885,000 and $1,307,000 in 1995, 1996 and 1997, and $713,000
and $2,509,000 for the six months ended March 31, 1997 and 1998 (unaudited),
respectively.
 
    Actual income tax expense differs from the amount computed using the federal
statutory rate of 34% for the years ended September 30, 1995, 1996 and 1997 and

    Management believes that it is more likely than not that future operations
will generate sufficient taxable income to realize the deferred tax assets.
 
(7) STOCKHOLDERS' EQUITY AND STOCK OPTIONS
 
    The Board of Directors may issue preferred stock with rates of dividends,
voting rights, redemption prices, liquidation prices, liquidation premiums,
conversion rights and other requirements without a vote of the shareholders.
 
    The Company currently has six nonqualified stock option plans under which
the Board of Directors may grant options to purchase approximately 267,000
shares of the Company's common stock to officers, directors and key employees.
The exercise price of the options is established by the Board of Directors on
the date of grant. Employees may vest in their options either 100% on date of
grant or 25% six months from date of grant and 25% on the anniversary of date of
grant thereafter, as determined by the Board of Directors. The options are
exercisable in whole or in part for a period of up to ten years from date of
grant.
 
    As discussed in note 1, the Company applies APB Opinion 25 and related
interpretations in accounting for its stock option plans. Accordingly, because
the Company grants its options at or above market value at date of grant, no
compensation cost has been recognized under the plans. Had compensation cost for
the Company's stock-based compensation plans been determined based upon the fair
value of options on the grant dates, consistent with the provisions of SFAS 123,
the Company's 1996 and 1997 pro

forma net income and diluted earnings per share would have been approximately
$1.8 million and $2.8 million and $.35 and $.50, respectively. The weighted
average fair value of options granted during 1996 and 1997 was $4.99 and $5.49
per share, respectively. The weighted average remaining contractual life of all
options at September 30, 1997 and March 31, 1998 was approximately three years.
 
    The fair value of each option grant was estimated at the date of grant using
the Black-Scholes option-pricing model with the following assumptions: no
expected dividends, expected life of the options of three years, 60% volatility
and a risk-free interest rate of 6.00%.
 
    Stock option activity for the plans for the years ended September 30, 1995,

(10) CONCENTRATIONS OF CREDIT RISK
 
    Financial instruments which potentially expose the Company to concentrations
of credit risk, as defined by Financial Accounting Standards Board's Statement
No. 105, Disclosure of Information about Financial Instruments with
Off-Balance-Sheet Risk and Financial Instruments with Concentration of Credit
Risk, consist primarily of accounts receivable with the Company's various
customers.
 
    Historically, the Company's customers have included cities, counties,
engineering companies, utility companies and federal government agencies.
Substantially more than 50% of revenues have historically been derived from
state and local government contracts. In addition, a significant portion of the
Company's revenues are generated from utility clients, both commercial and
municipal.
 
    The Company's accounts receivable are due from a variety of organizations
throughout the United States. The Company provides for uncollectible amounts
upon recognition of revenue and when specific credit and collection issues
arise. Management's estimates of uncollectible amounts have been adequate in
prior years, and management believes that all significant credit and collection
risks have been identified and adequately provided for at September 30, 1997 and
March 31, 1998.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 7-108-402 of the Colorado Business Corporation Act (the "Act")
provides, generally, that the articles of incorporation may contain a provision
eliminating or limiting the personal liability of a director to the corporation
or its shareholders for monetary damages for breach of fiduciary duty as a
director; except that any such provision may not eliminate or limit the
liability of a director (i) for any breach of the director's duty of loyalty to
the corporation or its shareholders, (ii) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) acts
specified in Section 7-108-403, or (iv) any transaction from which a director
directly or indirectly derived an improper personal benefit. Such provision may
not eliminate or limit the liability of a director for any act or omission
occurring prior to the date on which such provision becomes effective. The
Company's articles of incorporation contain such a provision.
 
    Section 7-109-103 of the Act provides, that a corporation organized under
Colorado law shall be required to indemnify a person who is or was a director of
the corporation or an individual who, while serving as a director of the
corporation, is or was serving at the corporation's request as a director,
officer, partner, trustee, employee or fiduciary or agent of another corporation
or other entity or of any employee benefit plan (a "Director") or officer of the
corporation and who was wholly successful, on the merits or otherwise, in
defense of any threatened, pending, or completed action, suit, or proceeding,
whether civil, criminal, administrative, or investigative and whether formal or
informal (a "Proceeding"), in which he was a party, against reasonable expenses
incurred by him in connection with the Proceeding, unless such indemnity is
limited by the corporation's articles of incorporation.
 
    Section 7-109-102 of the Act provides, generally, that a corporation may
indemnify a person made a party to a Proceeding because the person is or was a
Director against any obligation incurred with respect to a Proceeding to pay a
judgment, settlement, penalty, fine (including an excise tax assessed with
respect to an employee benefit plan) or reasonable expenses incurred in the
Proceeding if the person conducted himself or herself in good faith and the
person reasonably believed, in the case of conduct in an official capacity with
the corporation, the person's conduct was in the corporation's best interests
and, in all other
 
                                      II-1
<PAGE>
ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS. (CONTINUED)
cases, his or her conduct was at least not opposed to the corporation's best
interests and, with respect to any criminal proceedings, the person had no
reasonable cause to believe that his or her conduct was unlawful. A corporation
may not indemnify a Director in connection with any Proceeding by or in the
right of the corporation in which the Director was adjudged liable to the
corporation or, in connection with any other Proceeding charging the Director
derived an improper personal benefit, whether or not involving actions in an
official capacity, in which Proceeding the Director was judged liable on the
basis that he or she derived an improper personal benefit. Any indemnification
permitted in connection with a Proceeding by or in the right of the corporation
is limited to reasonable expenses incurred in connection with such Proceeding.
Under Section 7-109-107 of the Act, unless otherwise provided in the articles of
incorporation, a corporation may indemnify an officer, employee, fiduciary, or
agent of the corporation to the same extent as a Director and may indemnify an
officer, employee, fiduciary, or agent who is not a Director to a greater
extent, if not inconsistent with public policy and if provided for by its
bylaws, general or specific action of its board of directors or shareholders, or
contract.
 
    In addition, the Company's articles of incorporation provide that each
person who was or is made a party or is threatened to be made a party to or is
otherwise involved in any Proceeding by reason of the fact that he or she, or a
person of whom he or she is the legal representative, is or was a director,
officer or employee of the Company or is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans (an "indemnitee"), whether the basis of such
proceeding is alleged action in an official capacity as a director, officer,
employee or agent in any other capacity while serving as a director, officer,
employee or agent, shall be indemnified and held harmless by the corporation to
the fullest extent authorized by the Colorado Corporation Code against all
expense, liability and loss (including attorney's fees, judgments, fines, ERISA
excise taxes or penalties and amounts paid or to be paid in settlement)
reasonably incurred or suffered by such indemnitee in connection therewith. Such
indemnification shall continue as to an indemnitee who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
indemnitee's heirs, executors and administrators; provided, however, that,
except as provided in Paragraph (B) hereof with respect to proceedings to
enforce rights to indemnification, the Company shall indemnify any such
indemnitee in connection with a proceeding (or part thereof) initiated by such
indemnitee only if such proceeding (or part thereof) was authorized by the Board
of Directors of the Company.
 
    The Company's articles require that the Company maintain insurance to
protect itself and any director, officer, employee or agent of the corporation
or another corporation, partnership. joint venture, trust or other enterprise
against any such expense, liability or loss, whether or not the corporation
would have the power to indemnify such person against such expense, liability or
loss under the Act.
 
    The Company's articles of incorporation provide that the Company shall
indemnify any director or officer, or former director or officer, or any person
who may have served at its request as a director or officer of another
corporation in which it owns shares of capital stock, or of which it is a
creditor, and the personal representative of all such persons, against expenses
actually and necessarily incurred by him in connection with the defense of any
action, suit or proceeding in which he is made a party by reason of being or
having been such director or officer, except in relation to matters as to which
he shall be adjudged in such action, suit or proceedings, to be liable for
negligence or misconduct in the performance of duty; but such indemnification
shall not be deemed exclusive of any other rights to which such director or
officer may be entitled, under any by-law, agreement vote of shareholders, or
otherwise nor shall anything herein contained restrict the right of the
corporation to indemnify or reimburse such person in any proper case, even
though not specifically herein provided for. The Company, its directors,
officers, employees and agents shall be fully protected in taking any action or
making any payment under this provision, or in refusing so to do, in reliance
upon the advice of counsel.

ITEM 17. UNDERTAKINGS.
 
    (a) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    (b) The undersigned registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.
 
    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

                                                                   _______, 1998




NATIONSBANC MONTGOMERY SECURITIES LLC
DAIN RAUSCHER WESSELS, a division of Dain Rauscher Incorporated
As Representatives of the several Underwriters
c/o NATIONSBANC MONTGOMERY SECURITIES LLC
600 Montgomery Street
San Francisco, California  94111


Ladies and Gentlemen:

INTRODUCTORY.

     Analytical Surveys, Inc., a Colorado corporation (the "Company), proposes
to issue and sell to the several underwriters named in SCHEDULE A (the
"Underwriters") an aggregate of 1,750,000 shares of its Common Stock, no par
value per share (the "Common Stock"); and the shareholders of the Company named
on SCHEDULE B (collectively, the "Selling Shareholders") severally propose to
sell to the Underwriters an aggregate of 500,000 shares of Common Stock.  The
1,750,000 shares of Common Stock to be sold by the Company and the 500,000
shares of Common Stock to be sold by the Selling Shareholders are collectively
called the "Firm Common Shares". In addition, the Company has granted to the
Underwriters an option to purchase up to an additional 262,500 shares of Common
Stock and the Selling Shareholders have severally granted to the Underwriters an
option to purchase up to an additional 75,000 shares of Common Stock, each
Selling Shareholder selling up to the amount set forth opposite such Selling
Shareholder's name on SCHEDULE B, all as provided in Section 2.  The additional
262,500 shares to be sold by the Company and the additional 75,000 shares to be
sold by the Selling Shareholders pursuant to such option are collectively called
the "Optional Common Shares".  The Firm Common Shares and, if and to the extent
such option is exercised, the Optional Common Shares are collectively called the
"Common Shares".  NationsBanc Montgomery Securities LLC ("NMSI") and Dain
Rauscher Wessels, a division of Dain Rauscher Incorporated, have agreed to act
as representatives of the several Underwriters (in such capacity, the
"Representatives") in connection with the offering and sale of the Common
Shares.

     The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3 (File
No. 333-[___]), which contains a form of prospectus to be used in connection
with the public offering and sale of the Common Shares.  Such registration
statement, as amended, including the financial statements, exhibits and
schedules thereto, in the form in which it was declared effective by the
Commission under the Securities Act of 1933 and the rules and regulations
promulgated thereunder (collectively, the "Securities Act"), including all
documents incorporated or deemed incorporated by reference therein, any
information deemed to be a part thereof at the time of effectiveness pursuant to


                                          1
<PAGE>

Rule 430A or Rule 434 under the Securities Act or the Securities Exchange Act of
1934 and the rules and regulations promulgated thereunder (collectively, the
"Exchange Act"), is called the "Registration Statement".  Any registration
statement filed by the Company pursuant to Rule 462(b) under the Securities Act
is called the "Rule 462(b) Registration Statement", and from and after the date
and time of filing of the Rule 462(b) Registration Statement the term
"Registration Statement" shall include the Rule 462(b) Registration Statement.
Such prospectus, in the form first used by the Underwriters to confirm sales of
the Common Shares, is called the "Prospectus"; PROVIDED, HOWEVER, if the Company
has, with the consent of NMSI, elected to rely upon Rule 434 under the
Securities Act, the term "Prospectus" shall mean the Company's prospectus
subject to completion (each, a "preliminary prospectus") dated ______, 1998
(such preliminary prospectus is called the "Rule 434 preliminary prospectus"),
together with the applicable term sheet (the "Term Sheet") prepared and filed by
the Company with the Commission under Rules 434 and 424(b) under the Securities
Act and all references in this Agreement to the date of the Prospectus shall
mean the date of the Term Sheet.  All references in this Agreement to the
Registration Statement, the Rule 462(b) Registration Statement, a preliminary
prospectus, the Prospectus or the Term Sheet, or any amendments or supplements
to any of the foregoing, shall include any copy thereof filed with the
Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval
System ("EDGAR").

     All references in this Agreement to financial statements and schedules and
other information which is "contained," "included" or "stated" in the
Registration Statement or the Prospectus (and all other references of like
import) shall be deemed to mean and include all such financial statements and
schedules and other information which is or is deemed to be incorporated by
reference in the Registration Statement or the Prospectus, as the case may be;
and all references in this Agreement to amendments or supplements to the
Registration Statement or the Prospectus shall be deemed to mean and include the
filing of any document under the Exchange Act which is or is deemed to be
incorporated by reference in the Registration Statement or the Prospectus, as
the case may be.

     The Company and each of the Selling Shareholders hereby confirm their
respective agreements with the Underwriters as follows:

SECTION 1.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     A.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

     The Company hereby represents, warrants and covenants to each Underwriter
as follows:

        (a) COMPLIANCE WITH REGISTRATION REQUIREMENTS.

        The Registration Statement and any Rule 462(b) Registration Statement
   have been declared effective by the Commission under the Securities Act.
   The Company has complied to the Commission's satisfaction with all requests
   of the Commission for additional or supplemental information.  No stop order
   suspending the effectiveness of the Registration Statement or any
   Rule 462(b) Registration Statement is in effect and no proceedings for such
   purpose have been instituted or are pending or, to the best knowledge of the
   Company, are contemplated or threatened by the Commission.

        Each preliminary prospectus and the Prospectus when filed complied in
   all material respects with the Securities Act and, if filed by electronic
   transmission pursuant to EDGAR


                                          2
<PAGE>

   (except as may be permitted by Regulation S-T under the Securities Act), was
   identical to the copy thereof delivered to the Underwriters for use in
   connection with the offer and sale of the Common Shares.  Each of the
   Registration Statement, any Rule 462(b) Registration Statement and any
   post-effective amendment thereto, at the time it became effective and at all
   subsequent times, complied and will comply in all material respects with the
   Securities Act and did not and will not contain any untrue statement of a
   material fact or omit to state a material fact required to be stated therein
   or necessary to make the statements therein not misleading.  The Prospectus,
   as amended or supplemented, as of its date and at all subsequent times, did
   not and will not contain any untrue statement of a material fact or omit to
   state a material fact necessary in order to make the statements therein, in
   the light of the circumstances under which they were made, not misleading.
   The representations and warranties set forth in the two immediately
   preceding sentences do not apply to statements in or omissions from the
   Registration Statement, any Rule 462(b) Registration Statement, or any
   post-effective amendment thereto, or the Prospectus, or any amendments or
   supplements thereto, made in reliance upon and in conformity with
   information relating to any Underwriter furnished to the Company in writing
   by the Representatives expressly for use therein.  There are no contracts or
   other documents required to be described in the Prospectus or to be filed as
   exhibits to the Registration Statement which have not been described or
   filed as required.


        (b) OFFERING MATERIALS FURNISHED TO UNDERWRITERS.

        The Company has delivered to each of the Representatives one complete
   manually signed copy of the Registration Statement and of each consent and
   certificate of experts filed as a part thereof, and conformed copies of the
   Registration Statement (without exhibits) and preliminary prospectuses and
   the Prospectus, as amended or supplemented, in such quantities and at such
   places as the Representatives have reasonably requested for each of the
   Underwriters.

        (c) DISTRIBUTION OF OFFERING MATERIAL BY THE COMPANY.

        The Company has not distributed and will not distribute, prior to the
   later of the Second Closing Date (as defined below) and the completion of
   the Underwriters' distribution of the Common Shares, any offering material
   in connection with the offering and sale of the Common Shares other than a
   preliminary prospectus, the Prospectus or the Registration Statement.

        (d) THE UNDERWRITING AGREEMENT.

        This Agreement has been duly authorized, executed and delivered by, and
   is a valid and binding agreement of, the Company, enforceable in accordance
   with its terms, except as rights to indemnification hereunder may be limited
   by applicable law and except as the enforcement hereof may be limited by
   bankruptcy, insolvency, reorganization, moratorium or other similar laws
   relating to or affecting the rights and remedies of creditors or by general
   equitable principles.

        (e) AUTHORIZATION OF THE COMMON.

        The Common Shares to be purchased by the Underwriters from the Company
   have been duly authorized for issuance and sale pursuant to this Agreement
   and, when issued and


                                          3
<PAGE>

   delivered by the Company pursuant to this Agreement, will be validly issued,
   fully paid and nonassessable.

        (f) NO APPLICABLE REGISTRATION OR OTHER SIMILAR RIGHTS.

        There are no persons with registration or other similar rights to have
   any equity or debt securities registered for sale under the Registration
   Statement or included in the offering contemplated by this Agreement other
   than the Selling Shareholders with respect to the Common Shares included in
   the Registration Statement, except for such rights as have been exercised or
   duly and validly waived.

        (g) NO MATERIAL ADVERSE CHANGE.

        Except as otherwise disclosed in the Prospectus, subsequent to the
   respective dates as of which information is given in the Prospectus: (i)
   there has been no material adverse change, or any development that could
   reasonably be expected to result in a material adverse change, in the
   condition, financial or otherwise, or in the earnings, business, operations
   or prospects, whether or not arising from transactions in the ordinary
   course of business, of the Company and its subsidiaries, considered as one
   entity (any such change is called a "Material Adverse Change"); (ii) the
   Company and its subsidiaries, considered as one entity, have not incurred
   any material liability or obligation, indirect, direct or contingent, not in
   the ordinary course of business nor entered into any material transaction or
   agreement not in the ordinary course of business; and (iii) there has been
   no dividend or distribution of any kind declared, paid or made by the
   Company or, except for dividends paid to the Company or other subsidiaries,
   any of its subsidiaries on any class of capital stock or repurchase or
   redemption by the Company or any of its subsidiaries of any class of capital
   stock.

        (h) INDEPENDENT ACCOUNTANTS.

        KPMG Peat Marwick LLP, who have expressed their opinion with respect to
   the financial statements (which term as used in this Agreement includes the
   related notes thereto) and supporting schedules filed with the Commission as
   a part of the Registration Statement and included in the Prospectus, are
   independent public or certified public accountants as required by the
   Securities Act and the Exchange Act.

        (i) PREPARATION OF THE FINANCIAL STATEMENTS.

        The financial statements filed with the Commission as a part of the
   Registration Statement and included in the Prospectus present fairly the
   consolidated financial position of the Company and its subsidiaries as of
   and at the dates indicated and the results of their operations and cash
   flows for the periods specified.  The supporting schedules included in the
   Registration Statement present fairly the information required to be stated
   therein.  Such financial statements and supporting schedules have been
   prepared in conformity with generally accepted accounting principles applied
   on a consistent basis throughout the periods involved, except as may be
   expressly stated in the related notes thereto.  No other financial
   statements or supporting schedules are required to be included in the
   Registration Statement.  The financial data set forth in the Prospectus
   under the captions "Prospectus Summary--Summary Selected Financial Data",
   "Selected Financial Data" and "Capitalization" fairly present the
   information set forth therein on a basis consistent with that of the audited
   financial statements contained in the Registration Statement.


                                          4

        (j) INCORPORATION AND GOOD STANDING OF THE COMPANY AND ITS
            SUBSIDIARIES.

        Each of the Company and its subsidiaries has been duly incorporated and
   is validly existing as a corporation in good standing under the laws of the
   jurisdiction of its incorporation and has corporate power and authority to
   own, lease and operate its properties and to conduct its business as
   described in the Prospectus and, in the case of the Company, to enter into
   and perform its obligations under this Agreement.  The Company is duly
   qualified as a foreign corporation to transact business and is in good
   standing in Indiana, North Carolina, Texas and Wisconsin and each of the
   Company and each subsidiary is duly qualified as a foreign corporation to
   transact business and is in good standing in each other jurisdiction in
   which such qualification is required, whether by reason of the ownership or
   leasing of property or the conduct of business, except for such
   jurisdictions where the failure to so qualify or to be in good standing
   would not, individually or in the aggregate, result in a Material Adverse
   Change.  All of the issued and outstanding capital stock of each subsidiary
   has been duly authorized and validly issued, is fully paid and nonassessable
   and is owned by the Company, directly or through subsidiaries, free and
   clear of any security interest, mortgage, pledge, lien, encumbrance or
   claim.  The Company does not own or control, directly or indirectly, any
   corporation, association or other entity other than the subsidiaries listed
   in Exhibit 22i  to the Company's Annual Report on Form 10-K for the fiscal
   year ended September 30, 1997, Cartotech, Inc. and Interra Technologies.

        (k) CAPITALIZATION AND OTHER CAPITAL STOCK MATTERS.

        The authorized, issued and outstanding capital stock of the Company is
   as set forth in the Prospectus under the caption "Capitalization" (other
   than for subsequent issuances, if any, pursuant to employee benefit plans
   described in the Prospectus or upon exercise of outstanding options or
   warrants described in the Prospectus).  The Common Stock (including the
   Common Shares) conforms in all material respects to the description thereof
   contained in or incorporated by reference into the Prospectus.  All of the
   issued and outstanding shares of Common Stock (including the shares of
   Common Stock owned by Selling Shareholders) have been duly authorized and
   validly issued, are fully paid and nonassessable and have been issued in
   compliance with federal and state securities laws.  None of the outstanding
   shares of Common Stock were issued in violation of any preemptive rights,
   rights of first refusal or other similar rights to subscribe for or purchase
   securities of the Company.  There are no authorized or outstanding options,
   warrants, preemptive rights, rights of first refusal or other rights to
   purchase, or equity or debt securities convertible into or exchangeable or
   exercisable for, any capital stock of the Company or any of its subsidiaries
   other than those accurately described in the Prospectus.  The description of
   the Company's stock option, stock bonus and other stock plans or
   arrangements, and the options or other rights granted thereunder, set forth
   in or incorporated by reference into the Prospectus accurately and fairly
   presents the information required to be shown with respect to such plans,
   arrangements, options and rights.


                                          5
<PAGE>

        (l) STOCK EXCHANGE LISTING.

        The Common Stock (including the Common  Shares) is registered pursuant
   to Section 12(g) of the Exchange Act and is listed on the Nasdaq National
   Market, and the Company has taken no action designed to, or likely to have
   the effect of, terminating the registration of the Common Stock under the
   Exchange Act or delisting the Common Stock from the Nasdaq National Market
   nor has the Company received any notification that the Commission or the
   National Association of Securities Dealers, Inc. (the "NASD") is
   contemplating terminating such registration or listing.

        (m) NON-CONTRAVENTION OF EXISTING INSTRUMENTS; NO FURTHER
            AUTHORIZATIONS OR APPROVALS REQUIRED.

        Neither the Company nor any of its subsidiaries is in violation of its
   charter or by-laws or is in default (or, with the giving of notice or lapse
   of time, would be in default) ("Default") under any indenture, mortgage,
   loan or credit agreement, note, contract, franchise, lease or other
   instrument to which the Company or any of its subsidiaries is a party or by
   which it or any of them may be bound (including, without limitation, the
   Company's term loan and lines of credit with BankOne Colorado N.A., or to
   which any of the property or assets of the Company or any of its
   subsidiaries is subject (each, an "Existing Instrument"), except for such
   Defaults as would not, individually or in the aggregate, result in a
   Material Adverse Change.  The Company's execution, delivery and performance
   of this Agreement and consummation of the transactions contemplated hereby
   and by the Prospectus (i) have been duly authorized by all necessary
   corporate action and will not result in any violation of the provisions of
   the charter or by-laws of the Company or any subsidiary, (ii) will not
   conflict with or constitute a breach of, or Default under, or result in the
   creation or imposition of any lien, charge or encumbrance upon any property
   or assets of the Company or any of its subsidiaries pursuant to, or require
   the consent of any other party to, any Existing Instrument, except for such
   conflicts, breaches, Defaults, liens, charges or encumbrances as would not,
   individually or in the aggregate, result in a Material Adverse Change, and
   (iii) will not result in any violation of any law, administrative regulation
   or administrative or court decree applicable to the Company or any
   subsidiary.  No consent, approval, authorization or other order of, or
   registration or filing with, any court or other governmental or regulatory
   authority or agency, is required for the Company's execution, delivery and
   performance of this Agreement and consummation of the transactions
   contemplated hereby and by the Prospectus, except such as have been obtained
   or made by the Company and are in full force and effect under the Securities
   Act, applicable state securities or blue sky laws and from the NASD.

        (n) NO MATERIAL ACTIONS OR PROCEEDINGS.

        There are no legal or governmental actions, suits or proceedings
   pending or, to the best of the Company's knowledge, threatened (i) against
   or affecting the Company or any of its subsidiaries, (ii) which has as the
   subject thereof any officer or director of, or property owned or leased by,
   the Company or any of its subsidiaries, or (iii) relating to environmental
   or discrimination matters, where in any such case (A) there is a reasonable
   possibility that such action, suit or proceeding might be determined
   adversely to the Company or such subsidiary and (B) any such action, suit or
   proceeding, if so determined adversely, would reasonably be expected to
   result in a Material Adverse Change or adversely affect the consummation of
   the transactions contemplated by this Agreement.  No material labor


                                          6
<PAGE>

   dispute with the employees of the Company or any of its subsidiaries exists
   or, to the best of the Company's knowledge, is threatened or imminent.

        (o) INTELLECTUAL PROPERTY RIGHTS.

        The Company and its subsidiaries own or possess sufficient trademarks,
   trade names, patent rights, copyrights, licenses, approvals, trade secrets
   and other similar rights (collectively, "Intellectual Property Rights")
   reasonably necessary to conduct their businesses as now conducted, and the
   expected expiration of any of such Intellectual Property Rights would not
   result in a Material Adverse Change.  Neither the Company nor any of its
   subsidiaries has received any notice of infringement or conflict with
   asserted Intellectual Property Rights of others, which infringement or
   conflict, if the subject of an unfavorable decision, would result in a
   Material Adverse Change.

        (p) ALL NECESSARY PERMITS, ETC.

        The Company and each subsidiary possess such valid and current
   certificates, authorizations or permits issued by the appropriate state,
   federal or foreign regulatory agencies or bodies necessary to conduct their
   respective businesses, and neither the Company nor any subsidiary has
   received any notice of proceedings relating to the revocation or
   modification of, or non-compliance with, any such certificate, authorization
   or permit which, singly or in the aggregate, if the subject of an
   unfavorable decision, ruling or finding, could result in a Material Adverse
   Change.

        (q) TITLE TO PROPERTIES.

        The Company and each of its subsidiaries has good and marketable title
   to all the properties and assets reflected as owned in the financial
   statements referred to in Section 1(A) (i) above (or elsewhere in the
   Prospectus), in each case free and clear of any security interests,
   mortgages, liens, encumbrances, equities, claims and other defects, except
   such as do not materially affect the value of such property so as to cause a
   Material Adverse Change and do not interfere with the use made or proposed
   to be made of such property by the Company or such subsidiary so as to cause
   a Material Adverse Change.  The real property, improvements, equipment and
   personal property held under lease by the Company or any subsidiary are held
   under valid and enforceable leases, with such exceptions as are not material
   and do not interfere with the use made or proposed to be made of such real
   property, improvements, equipment or personal property by the Company or
   such subsidiary so as to cause a Material Adverse Change.

        (r) TAX LAW COMPLIANCE.

        The Company and its subsidiaries have filed all necessary federal,
   state and foreign income and franchise tax returns or have properly
   requested extensions thereof and have paid all taxes required to be paid by
   any of them and, if due and payable, any related or similar assessment, fine
   or penalty levied against any of them, except such as would not result in a
   Material Adverse Change. The Company has made adequate charges, accruals and
   reserves in the applicable financial statements referred to in Section 1(A)
   (i) above in respect of all federal, state and foreign income and franchise
   taxes for all periods as to which the tax liability of the Company or any of
   its subsidiaries has not been finally determined, except such as would not
   result in a Material Adverse Change.


                                          7

        (s) COMPANY NOT AN "INVESTMENT COMPANY".

        The Company has been advised of the rules and requirements under the
   Investment Company Act of 1940, as amended (the "Investment Company Act").
   The Company is not, and after receipt of payment for the Common Shares will
   not be, an "investment company" within the meaning of Investment Company Act
   and will conduct its business in a manner so that it will not become subject
   to the Investment Company Act.

        (t) INSURANCE.

        Each of the Company and its subsidiaries are insured by recognized,
   financially sound and reputable institutions with policies in such amounts
   and with such deductibles and, in the reasonable judgement of the Company,
   covering such risks as are generally deemed adequate and customary for their
   businesses including, but not limited to, policies covering real and
   personal property owned or leased by the Company and its subsidiaries
   against theft, damage, destruction, acts of vandalism and earthquakes.  The
   Company has no reason to believe that it or any subsidiary will not be able
   (i) to renew its existing insurance coverage as and when such policies
   expire or (ii) to obtain comparable coverage from similar institutions as
   may be necessary or appropriate to conduct its business as now conducted and
   at a cost that would not result in a Material Adverse Change.  Since January
   1, 1993, neither the Company nor any subsidiary has been denied any
   insurance coverage which it has sought or for which it has applied.

        (u) NO PRICE STABILIZATION OR MANIPULATION.

        The Company has not taken and will not take, directly or indirectly,
   any action designed to or that might be reasonably expected to cause or
   result in stabilization or manipulation of the price of any security of the
   Company to facilitate the sale or resale of the Common Shares.

        (v) RELATED PARTY TRANSACTIONS.

        There are no business relationships or related-party transactions
   involving the Company or any subsidiary or any other person required to be
   described in the Prospectus which have not been described as required.

        (w) NO UNLAWFUL CONTRIBUTIONS OR OTHER PAYMENTS.

        Neither the Company nor any of its subsidiaries nor, to the best of the
   Company's knowledge, any employee or agent of the Company or any subsidiary,
   has made any contribution or other payment to any official of, or candidate
   for, any federal, state or foreign office in violation of any law or of the
   character required to be disclosed in the Prospectus.

        (x) COMPLIANCE WITH ENVIRONMENTAL LAWS.

        Except as would not, individually or in the aggregate, result in a
   Material Adverse Change (i)  neither the Company nor any of its subsidiaries
   is in violation of any federal,


                                          8
<PAGE>

   state, local or foreign law or regulation relating to pollution or
   protection of human health or the environment (including, without
   limitation, ambient air, surface water, groundwater, land surface or
   subsurface strata) or wildlife, including without limitation, laws and
   regulations relating to emissions, discharges, releases or threatened
   releases of chemicals, pollutants, contaminants, wastes, toxic substances,
   hazardous substances, petroleum and petroleum products (collectively,
   "Materials of Environmental Concern"), or otherwise relating to the
   manufacture, processing, distribution, use, treatment, storage, disposal,
   transport or handling of Materials of Environment Concern (collectively,
   "Environmental Laws"), which violation includes, but is not limited to,
   noncompliance with any permits or other governmental authorizations required
   for the operation of the business of the Company or its subsidiaries under
   applicable Environmental Laws, or noncompliance with the terms and
   conditions thereof, nor has the Company or any of its subsidiaries received
   any written communication, whether from a governmental authority, citizens
   group, employee or otherwise, that alleges that the Company or any of its
   subsidiaries is in violation of any Environmental Law; (ii) there is no
   claim, action or cause of action filed with a court or governmental
   authority, no investigation with respect to which the Company has received
   written notice, and no written notice by any person or entity alleging
   potential liability for investigatory costs, cleanup costs, governmental
   responses costs, natural resources damages, property damages, personal
   injuries, attorneys' fees or penalties arising out of, based on or resulting
   from the presence, or release into the environment, of any Material of
   Environmental Concern at any location owned, leased or operated by the
   Company or any of its subsidiaries, now or in the past (collectively,
   "Environmental Claims"), pending or, to the best of the Company's knowledge,
   threatened against the Company or any of its subsidiaries or any person or
   entity whose liability for any Environmental Claim the Company or any of its
   subsidiaries has retained or assumed either contractually or by operation of
   law; and (iii) to the best of the Company's knowledge, there are no past or
   present actions, activities, circumstances, conditions, events or incidents,
   including, without limitation, the release, emission, discharge, presence or
   disposal of any Material of Environmental Concern, that reasonably could be
   expected to result in a violation of any Environmental Law or form the basis
   of a potential Environmental Claim against the Company or any of its
   subsidiaries or against any person or entity whose liability for any
   Environmental Claim the Company or any of its subsidiaries has retained or
   assumed either contractually or by operation of law.

        (y) ERISA COMPLIANCE.

        The Company and its subsidiaries and any "employee benefit plan" (as
   defined under the Employee Retirement Income Security Act of 1974, as
   amended, and the regulations and published interpretations thereunder
   (collectively, "ERISA")) established or maintained by the Company, its
   subsidiaries or their "ERISA Affiliates" (as defined below) are in
   compliance with ERISA except for such instances that singly or in the
   aggregate would not result in a Material Adverse Change.  "ERISA Affiliate"
   means, with respect to the Company or a subsidiary, any member of any group
   of organizations described in Sections 414(b), (c), (m) or (o) of the
   Internal Revenue Code of 1986, as amended, and the regulations and published
   interpretations thereunder (the "Code") of which the Company or such
   subsidiary is a member.  No "reportable event" (as defined under ERISA) has
   occurred or is reasonably expected to occur with respect to any "employee
   benefit plan" established or maintained by the Company, its subsidiaries or
   any of their ERISA Affiliates except for such instances that singly or in
   the aggregate would not result in a Material Adverse Change.  No "employee
   benefit plan" established or maintained by the Company, its subsidiaries or
   any of their ERISA Affiliates, if such "employee benefit plan" was
   terminated, would have any "amount


                                          9
<PAGE>

   of unfunded benefit liabilities" (as defined under ERISA), except for such
   instances that singly or in the aggregate would not result in a Material
   Adverse Change.  Neither the Company, its subsidiaries nor any of their
   ERISA Affiliates has incurred or reasonably expects to incur any liability
   under (i) Title IV of ERISA with respect to termination of, or withdrawal
   from, any "employee benefit plan" or (ii) Sections 412, 4971, 4975 or 4980B
   of the Code, except for such instances that singly or in the aggregate would
   not result in a Material Adverse Change. Each "employee benefit plan"
   established or maintained by the Company, its subsidiaries or any of their
   ERISA Affiliates that is intended to be qualified under Section 401(a) of
   the Code is so qualified and nothing has occurred, whether by action or
   failure to act, which would cause the loss of such qualification.

        (z) EXCHANGE ACT COMPLIANCE.

        The documents incorporated or deemed to be incorporated by reference in
   the Prospectus, at the time they were or hereafter are filed with the
   Commission, complied and will comply in all material respects with the
   requirements of the Exchange Act, and, when read together with the other
   information in the Prospectus, at the time the Registration Statement and
   any amendments thereto become effective and at the First Closing Date and
   the Second Closing Date, as the case may be, will not contain an untrue
   statement of a material fact or omit to state a material fact required to be
   stated therein or necessary to make the fact required to be stated therein
   or necessary to make the statements therein, in the light of the
   circumstances under which they were made, not misleading.

        Any certificate signed by an officer of the Company and delivered to
   the Representatives or to counsel for the Underwriters shall be deemed to be
   a representation and warranty by the Company to each Underwriter as to the
   matters set forth therein.

     B.  REPRESENTATIONS AND WARRANTIES OF THE SELLING SHAREHOLDERS.

     Each Selling Shareholder severally represents, warrants and covenants to
each Underwriter as follows:

        (a) THE UNDERWRITING AGREEMENT.

        This Agreement has been duly authorized, executed and delivered by or
   on behalf of such Selling Shareholder and is a valid and binding agreement
   of such Selling Shareholder, enforceable in accordance with its terms,
   except as rights to indemnification and contribution hereunder may be
   limited by applicable law and except as the enforcement hereof may be
   limited by bankruptcy, insolvency, reorganization, moratorium or other
   similar laws relating to or affecting the rights and remedies of creditors
   or by general equitable principles.

        (b) THE CUSTODY AGREEMENT AND POWER OF ATTORNEY.

        Each of the (i) Custody Agreement signed by such Selling Shareholder
   and American Securities Transfer Inc., as custodian (the "Custodian"),
   relating to the deposit of the Common Shares to be sold by such Selling
   Shareholder (the "Custody Agreement") and (ii) Power of Attorney appointing
   certain individuals named therein as such Selling Shareholder's
   attorneys-in-fact (each, an "Attorney-in-Fact") to the extent set forth
   therein relating to the transactions contemplated hereby and by the
   Prospectus (the "Power of Attorney"), of such Selling Shareholder has been
   duly authorized, executed and delivered by


                                          10

   such Selling Shareholder and is a valid and binding agreement of such
   Selling Shareholder, enforceable in accordance with its terms, except as
   rights to indemnification thereunder may be limited by applicable law and
   except as the enforcement thereof may be limited by bankruptcy, insolvency,
   reorganization, moratorium or other similar laws relating to or affecting
   the rights and remedies of creditors or by general equitable principles.

        (c) TITLE TO COMMON SHARES TO BE SOLD; ALL AUTHORIZATIONS OBTAINED.

        Such Selling Shareholder has, and on the First Closing Date and the
   Second Closing Date (as defined below) will have, good and valid title to
   all of the Common Shares which may be sold by such Selling Shareholder
   pursuant to this Agreement on such date and the legal right and power
   required by law to enter into this Agreement and its Custody Agreement and
   Power of Attorney, to sell, transfer and deliver all of the Common Shares
   which may be sold by such Selling Shareholder pursuant to this Agreement and
   to comply with its other obligations hereunder and thereunder.

        (d) DELIVERY OF THE COMMON SHARES TO BE SOLD.

        Delivery of and payment for the Common Shares which are sold by such
   Selling Shareholder pursuant to this Agreement will pass good and valid
   title to such Common Shares, free and clear of any security interest,
   mortgage, pledge, lien, encumbrance or other claim, assuming that the
   purchaser of such Common Stock acquires such Common Stock with due power and
   authority.

        (e) NON-CONTRAVENTION; NO FURTHER AUTHORIZATIONS OR APPROVALS
            REQUIRED.

        The execution and delivery by such Selling Shareholder of, and the
   performance by such Selling Shareholder of its obligations under, this
   Agreement, the Custody Agreement and the Power of Attorney will not
   contravene or conflict with, result in a breach of, or constitute a Default
   under, or require the consent of any other party to, the charter or by-laws,
   partnership agreement, trust agreement or other organizational documents of
   such Selling Shareholder or any other agreement or instrument to which such
   Selling Shareholder is a party or by which it is bound or under which it is
   entitled to any right or benefit (other than the consents and waivers
   referred to in section 1(B) (g) hereof), any provision of applicable law or
   any judgment, order, decree or regulation applicable to such Selling
   Shareholder of any court, regulatory body, administrative agency,
   governmental body or arbitrator having jurisdiction over such Selling
   Shareholder.  No consent, approval, authorization or other order of, or
   registration or filing with, any court or other governmental authority or
   agency, is required for the consummation by such Selling Shareholder of the
   transactions contemplated in this Agreement, except as provided in Section
   1(B)(g) hereof and except for the registration of the Common Shares under
   the Securities Act and such approvals, authorizations, registrations or
   qualifications as may be required under the Securities Act, applicable state
   securities or blue sky laws and from the NASD.

        (f) NO REGISTRATION OR OTHER SIMILAR RIGHTS.

        Such Selling Shareholder does not have any registration or other
   similar rights to have any equity or debt securities registered for sale by
   the Company under the Registration


                                          11
<PAGE>

   Statement or included in the offering contemplated by this Agreement, except
   for such rights as are described in the Prospectus under "Shares Eligible
   for Future Sale".

        (g) NO FURTHER CONSENTS, ETC.

        Except for the (i) exercise by Sol C. Miller of certain registration
   rights pursuant to that Registration Rights Agreement dated as of July 2,
   1997 (the "Miller Registration Rights Agreement"), (ii) consent of such
   Selling Shareholder to the respective number of Common Shares to be sold by
   each of the Selling Shareholders pursuant to this Agreement and (iii)
   waiver by the Company of certain provisions contained in the Miller
   Registration Rights Agreement as to the number of Common Shares to be sold
   by Sol C. Miller in the offering, no consent, approval or waiver is required
   under any instrument or agreement to which such Selling Shareholder is a
   party or by which it is bound or under which it is entitled to any right or
   benefit, in connection with the offering, sale or purchase by the
   Underwriters of any of the Common Shares which may be sold by such Selling
   Shareholder under this Agreement or the consummation by such Selling
   Shareholder of any of the other transactions contemplated hereby.

        (h) DISCLOSURE MADE BY SUCH SELLING SHAREHOLDER IN THE PROSPECTUS.

        All information furnished by or on behalf of such Selling Shareholder
   in writing to the Company expressly for use in the Registration Statement
   and Prospectus is, and on the First Closing Date and the Second Closing Date
   will be, true, correct, and complete in all material respects, and does not,
   and on the First Closing Date and the Second Closing Date will not, contain
   any untrue statement of a material fact or omit to state any material fact
   necessary to make such information not misleading.  Such Selling Shareholder
   confirms as accurate the number of shares of Common Stock set forth opposite
   such Selling Shareholder's name in the Prospectus under the caption
   "Principal and Selling Shareholders" (both prior to and after giving effect
   to the sale of the Common Shares).

        (i) NO PRICE STABILIZATION OR MANIPULATION.

        Such Selling Shareholder has not taken and will not take, directly or
   indirectly, any action designed to or that might be reasonably expected to
   cause or result in stabilization or manipulation of the price of any
   security of the Company to facilitate the sale or resale of the Common
   Shares.

        (j) CONFIRMATION OF COMPANY REPRESENTATIONS AND WARRANTIES.

      Such Selling Shareholder has no reason to believe that the
   representations and warranties of the Company contained in Section 1(A)
   hereof are not true and correct in all material respects, is familiar with
   the Registration Statement and the Prospectus and has no knowledge of any
   material fact, condition or information not disclosed in the Registration
   Statement or the Prospectus which has had or may have a Material Adverse
   Change and is not prompted to sell shares of Common Stock by any information
   concerning the Company which is not set forth in the Registration Statement
   and the Prospectus.

   Any certificate signed by or on behalf of any Selling Shareholder and
delivered to the Representatives or to counsel for the Underwriters shall be
deemed to be a representation and warranty by such Selling Shareholder to each
Underwriter as to the matters covered thereby.

SECTION 2.  PURCHASE, SALE AND DELIVERY OF THE COMMON SHARES.

     A.     THE FIRM COMMON SHARES.

     Upon the terms herein set forth, (i) the Company agrees to issue and sell
to the several Underwriters an aggregate of 1,750,000 Firm Common Shares and
(ii) the Selling Shareholders agree to sell to the several Underwriters an
aggregate of 500,000 Firm Common Shares, each Selling Shareholder selling the
number of Firm Common Shares set forth opposite such Selling Shareholder's name
on SCHEDULE B.  On the basis of the representations, warranties and agreements
herein contained, and upon the terms but subject to the conditions herein set
forth, the Underwriters agree, severally and not jointly, to purchase from the
Company and the Selling Shareholders the respective number of Firm Common Shares
set forth opposite their names on SCHEDULE A.  The purchase price per Firm
Common Share to be paid by the several Underwriters to the Company and the
Selling Shareholders shall be $[___] per share.

     B.     THE FIRST CLOSING DATE.

     Delivery of certificates for the Firm Common Shares to be purchased by the
Underwriters and payment therefor shall be made at the offices of NMSI, 600
Montgomery Street, San Francisco, California  (or such other place as may be
agreed to by the Company and the Representatives) at 6:00 a.m. San Francisco
time, on [4TH BUSINESS DAY AFTER DATE OF THIS AGREEMENT] ______, 1998 or such
other time and date not later than 10:30 a.m. San Francisco time, on [10
BUSINESS DAYS AFTER THE 1ST CLOSING] ____, 1998 as the Representatives shall
designate by notice to the Company (the time and date of such closing are called
the "First Closing Date").  The Company and the Selling Shareholders hereby
acknowledge that circumstances under which the Representatives may provide
notice to postpone the First Closing Date as originally scheduled include, but
are in no way limited to, any determination by the Company, the Selling
Shareholders or the Representatives to recirculate to the public copies of an
amended or supplemented Prospectus or a delay as contemplated by the provisions
of Section 10.

     C.     THE OPTIONAL COMMON SHARES; THE SECOND CLOSING DATE.

     In addition, on the basis of the representations, warranties and agreements
herein contained, and upon the terms but subject to the conditions herein set
forth, the Company and the Selling Shareholders hereby grant an option to the
several Underwriters to purchase, severally and not jointly, up to an aggregate
of 337,500 Optional Common Shares from the Company and the Selling Shareholders
at the purchase price per share to be paid by the Underwriters for the Firm
Common Shares.  The option granted hereunder is for use by the Underwriters
solely in covering any over-allotments in connection with the sale and
distribution of the Firm Common Shares.  The option granted hereunder may be
exercised at any time (but not more than once) upon notice by the
Representatives to the Company and the Selling Shareholders, which notice may be
given at any time within 30 days from the date of this Agreement.  Such notice
shall set forth (i) the aggregate number of Optional Common Shares as to which
the Underwriters are exercising the option, (ii) the names and denominations in
which the certificates for the Optional Common Shares are to be registered and
(iii) the time, date and place at which such certificates will be delivered
(which time and date may be simultaneous with, but not earlier than, the First
Closing Date; and in such case the term "First Closing Date" shall refer to the
time and date of delivery of certificates for the Firm Common Shares and the
Optional Common Shares).  Such time and date of delivery, if subsequent to the
First Closing Date, is called the "Second Closing


                                          13
<PAGE>

Date" and shall be determined by the Representatives and shall not be earlier
than three nor later than five full business days after delivery of such notice
of exercise.  If any Optional Common Shares are to be purchased, (a) each
Underwriter agrees, severally and not jointly, to purchase the number of
Optional Common Shares (subject to such adjustments to eliminate fractional
shares as the Representatives may determine) that bears the same proportion to
the total number of Optional Common Shares to be purchased as the number of Firm
Common Shares set forth on SCHEDULE A opposite the name of such Underwriter
bears to the total number of Firm Common Shares and (b)  the Company and each
Selling Shareholder agrees, severally and not jointly, to sell the number of
Optional Common Shares (subject to such adjustments to eliminate fractional
shares as the Representatives may determine) that bears the same proportion to
the total number of Optional Common Shares to be sold as the number of Optional
Common Shares set forth in SCHEDULE B opposite the name of such Selling
Shareholder (or, in the case of the Company, as the number of Optional Common
Shares to be sold by the Company as set forth in the paragraph "Introductory" of
this Agreement) bears to the total number of Optional Common Shares.  The
Representatives may cancel the option at any time prior to its expiration by
giving written notice of such cancellation to the Company and the Selling
Shareholders.

     D.     PUBLIC OFFERING OF THE COMMON SHARES.

     The Representatives hereby advise the Company and the Selling Shareholders
that the Underwriters intend to offer for sale to the public, as described in
the Prospectus, their respective portions of the Common Shares as soon after
this Agreement has been executed and the Registration Statement has been
declared effective as the Representatives, in their sole judgment, have
determined is advisable and practicable.

     E.     PAYMENT FOR THE COMMON SHARES.

     Payment for the Common Shares to be sold by the Company shall be made at
the First Closing Date (and, if applicable, at the Second Closing Date) by wire
transfer of immediately available funds to the order of the Company.  Payment
for the Common Shares to be sold by the Selling Shareholders shall be made at
the First Closing Date (and, if applicable, at the Second Closing Date) by wire
transfer of immediately available funds to the order of the Custodian.

     It is understood that the Representatives have been authorized, for their
own accounts and the accounts of the several Underwriters, to accept delivery of
and receipt for, and make payment of the purchase price for, the Firm Common
Shares and any Optional Common Shares the Underwriters have agreed to purchase.
NMSI, individually and not as the Representative of the Underwriters, may (but
shall not be obligated to) make payment for any Common Shares to be purchased by
any Underwriter whose funds shall not have been received by the Representatives
by the First Closing Date or the Second Closing Date, as the case may be, for
the account of such Underwriter, but any such payment shall not relieve such
Underwriter from any of its obligations under this Agreement.

     Each Selling Shareholder hereby agrees that (i) it will pay all stock
transfer taxes, stamp duties and other similar taxes, if any, payable upon the
sale or delivery of the Common Shares to be sold by such Selling Shareholder to
the several Underwriters, or otherwise in connection with the performance of
such Selling Shareholder's obligations hereunder and (ii) the Custodian is
authorized to deduct for such payment any such amounts from the proceeds to such
Selling Shareholder hereunder and to hold such amounts for the account of such
Selling Shareholder with the Custodian under the Custody Agreement.


                                          14
<PAGE>

     F.     DELIVERY OF THE COMMON SHARES.

     The Company and the Selling Shareholders shall deliver, or cause to be
delivered, to the Representatives for the accounts of the several Underwriters
certificates for the Firm Common Shares to be sold by them at the First Closing
Date, against the irrevocable release of a wire transfer of immediately
available funds for the amount of the purchase price therefor.  The Company and
the Selling Shareholders shall also deliver, or cause to be delivered, to the
Representatives for the accounts of the several Underwriters, certificates for
the Optional Common Shares the Underwriters have agreed to purchase from them at
the First Closing Date or the Second Closing Date, as the case may be, against
the irrevocable release of a wire transfer of immediately available funds for
the amount of the purchase price therefor.  The certificates for the Common
Shares shall be in definitive form and registered in such names and
denominations as the Representatives shall have requested at least two full
business days prior to the First Closing Date (or the Second Closing Date, as
the case may be) and shall be made available for inspection on the business day
preceding the First Closing Date (or the Second Closing Date, as the case may
be) at a location in New York City as the Representatives may designate.  Time
shall be of the essence, and delivery at the time and place specified in this
Agreement is a further condition to the obligations of the Underwriters.

     G.     DELIVERY OF PROSPECTUS TO THE UNDERWRITERS.

     Not later than 12:00 p.m. on the second business day following the date the
Common Shares of released by the Underwriters for sale to the public, the
Company shall deliver or cause to be delivered copies of the Prospectus in such
quantities and at such places as the Representatives shall request.

SECTION 3.  ADDITIONAL COVENANTS OF THE COMPANY AND THE SELLING SHAREHOLDERS.

     A.     COVENANTS OF THE COMPANY.

     The Company further covenants and agrees with each Underwriter as follows:

       (a)   REPRESENTATIVES' REVIEW OF PROPOSED AMENDMENTS AND SUPPLEMENTS.

       During such period beginning on the date hereof and ending on the later
   of the First Closing Date or such date, as in the opinion of counsel for the
   Underwriters, the Prospectus is no longer required by law to be delivered in
   connection with sales by an Underwriter or dealer (the "Prospectus Delivery
   Period"), prior to amending or supplementing the Registration Statement
   (including any registration statement filed under Rule 462(b) under the
   Securities Act) or the Prospectus including any amendment or supplement
   through incorporation by reference of any report filed under the Exchange

   against any loss, claim, damage, liability or expense, as incurred, to which

                                          23
<PAGE>

   or (iv) in whole or in part upon any failure of the Company to perform its
   obligations hereunder or under law; or (v) any act or failure to act or any
   alleged act or failure to act by any Underwriter in connection with, or
   relating in any manner to, the Common Stock or the offering contemplated
   hereby, and which is included as part of or referred to in any loss, claim,
   damage, liability or action arising out of or based upon any matter covered
   by clause (i) or (ii) above, PROVIDED that the Company shall not be liable
   under this clause (v) to the extent that a court of competent jurisdiction
   shall have determined by a final judgment that such loss, claim, damage,
   liability or action resulted directly from any such acts or failures to act
   undertaken or omitted to be taken by such Underwriter through its bad faith
   or willful misconduct; and to reimburse each Underwriter and each such
   controlling person for any and all expenses (including the reasonable fees
   and disbursements of counsel chosen by NMSI) as such expenses are reasonably
   incurred by such Underwriter or such controlling person in connection with
   investigating, defending, settling (pursuant to Section 8(e)), compromising
   or paying any such loss, claim, damage, liability, expense or action;
   PROVIDED, HOWEVER, that the foregoing indemnity agreement shall not apply to
   any loss, claim, damage, liability or expense to the extent, but only to the
   extent, arising out of or based upon any untrue statement or alleged untrue
   statement or omission or alleged omission made in reliance upon and in
   conformity with written information furnished to the Company by the
   Representatives expressly for use in the Registration Statement, any
   preliminary prospectus or the Prospectus (or any amendment or supplement
   thereto); and PROVIDED, FURTHER, that with respect to any preliminary
   prospectus, the foregoing indemnity agreement shall not inure to the benefit
   of any Underwriter from whom the person asserting any loss, claim, damage,
   liability or expense purchased Common Shares, or any person controlling such
   Underwriter, if copies of the Prospectus were timely delivered to the
   Underwriter pursuant to Section 2 and a copy of the Prospectus (as then
   amended or supplemented if the Company shall have furnished any amendments
   or supplements thereto) was not sent or given by or on behalf of such
   Underwriter to such person, if required by law so to have been delivered, at
   or prior to the written confirmation of the sale of the Common Shares to
   such person, and if the Prospectus (as so amended or supplemented) would
   have cured the defect giving rise to such loss, claim, damage, liability or
   expense. The indemnity agreement set forth in this Section 8(a) shall be in
   addition to any liabilities that the Company may otherwise have.

       (b)   INDEMNIFICATION OF THE UNDERWRITERS BY THE SELLING SHAREHOLDERS.

       Each of the Selling Shareholders, severally and not jointly, agrees to
   indemnify and hold harmless each Underwriter, its officers and employees,
   and each person, if any, who controls any Underwriter within the meaning of
   the Securities Act and the Exchange Act against any loss, claim, damage,
   liability or expense, as incurred, to which such Underwriter or such
   controlling person may become subject, under the Securities Act, the
   Exchange Act or other federal or state statutory law or regulation, or at
   common law or otherwise (including in settlement of any litigation, if such
   settlement is effected with the written consent of such Selling
   Shareholder), insofar as such loss, claim, damage, liability or expense (or
   actions in respect thereof as contemplated below) arises out of or is based
   (i) upon any untrue statement or alleged untrue statement of a material fact
   contained in the Registration Statement, or any amendment thereto, including
   any information deemed to be a part thereof pursuant to Rule 430A or
   Rule 434 under the Securities Act, or the omission or alleged omission
   therefrom of a material fact required to be stated therein or necessary to
   make the statements therein not misleading to the extent that such untrue
   statement or alleged untrue statement or omission or alleged omission was
   made in reliance upon and in conformity with written information furnished
   to the Company or the Representatives, directly or through such


                                          24

   Selling Shareholder's representatives, specifically for inclusion therein;
   or (ii) upon any untrue statement or alleged untrue statement of a material
   fact contained in any preliminary prospectus or the Prospectus (or any
   amendment or supplement thereto), or the omission or alleged omission
   therefrom of a material fact necessary in order to make the statements
   therein, in the light of the circumstances under which they were made, not
   misleading to the extent that such untrue statement or alleged untrue
   statement or omission or alleged omission was made in reliance upon and in
   conformity with written information furnished to the Company or the
   Representatives, directly or through such Selling Shareholder's
   representatives, specifically for inclusion therein; or (iii) in whole or in
   part upon any inaccuracy in the representations and warranties of such
   Selling Shareholder contained herein; or (iv) in whole or in part upon any
   failure of such Selling Shareholder to perform their respective obligations
   hereunder or under law; or (v) any act or failure to act or any alleged act
   or failure to act by any Underwriter in connection with, or relating in any
   manner to, the Common Stock or the offering contemplated hereby, and which
   is included as part of or referred to in any loss, claim, damage, liability
   or action arising out of or based upon any matter covered by clause (i) or
   (ii) above, PROVIDED that such Selling Shareholder shall not be liable under
   this clause (v) to the extent that a court of competent jurisdiction shall
   have determined by a final judgment that such loss, claim, damage, liability
   or action resulted directly from any such acts or failures to act undertaken
   or omitted to be taken by such Underwriter through its bad faith or willful
   misconduct; and to reimburse each Underwriter and each such controlling
   person for any and all expenses (including the reasonable fees and
   disbursements of counsel chosen by NMSI) as such expenses are reasonably
   incurred by such Underwriter or such controlling person in connection with
   investigating, defending, settling (pursuant to Section 8(e)), compromising
   or paying any such loss, claim, damage, liability, expense or action;
   PROVIDED, HOWEVER, that the foregoing indemnity agreement shall not apply to
   any loss, claim, damage, liability or expense to the extent, but only to the
   extent, arising out of or based upon any untrue statement or alleged untrue
   statement or omission or alleged omission made in reliance upon and in
   conformity with written information furnished to the Company by the
   Representatives expressly for use in the Registration Statement, any
   preliminary prospectus or the Prospectus (or any amendment or supplement
   thereto); and PROVIDED, FURTHER, that with respect to any preliminary
   prospectus, the foregoing indemnity agreement shall not inure to the benefit
   of any Underwriter from whom the person asserting any loss, claim, damage,
   liability or expense purchased Common Shares, or any person controlling such
   Underwriter, if copies of the Prospectus were timely delivered to the
   Underwriter pursuant to Section 2 and a copy of the Prospectus (as then
   amended or supplemented if the Company shall have furnished any amendments
   or supplements thereto) was not sent or given by or on behalf of such
   Underwriter to such person, if required by law so to have been delivered, at
   or prior to the written confirmation of the sale of the Common Shares to
   such person, and if the Prospectus (as so amended or supplemented) would
   have cured the defect giving rise to such loss, claim, damage, liability or
   expense; and PROVIDED, FURTHER, that with respect to any untrue statement or
   omission made in the Registration Statement, the Prospectus or any
   supplement or amendment thereto, the liability of each Selling Shareholder
   under this paragraph shall be limited to an amount equal to the net proceeds
   received by the Selling Shareholders from the sale of the Common Shares sold
   by such Selling Shareholder to the Underwriters pursuant to the terms
   hereof.  The indemnity agreement set forth in this Section 8(b) shall be in
   addition to any liabilities that the Selling Shareholders may otherwise
   have.

<PAGE>

       (c)   INDEMNIFICATION OF THE COMPANY, ITS DIRECTORS AND OFFICERS BY THE
             UNDERWRITERS.

       Each Underwriter agrees, severally and not jointly, to indemnify and
   hold harmless the Company, each of its directors, each of its officers who
   signed the Registration Statement, the Selling Shareholders and each person,
   if any, who controls the Company or any Selling Shareholder within the
   meaning of the Securities Act or the Exchange Act, against any loss, claim,
   damage, liability or expense, as incurred, to which the Company, or any such
   director, officer, Selling Shareholder or controlling person may become
   subject, under the Securities Act, the Exchange Act, or other federal or
   state statutory law or regulation, or at common law or otherwise (including
   in settlement of any litigation, if such settlement is effected with the
   written consent of such Underwriter), insofar as such loss, claim, damage,
   liability or expense (or actions in respect thereof as contemplated below)
   arises out of or is based upon any untrue or alleged untrue statement of a
   material fact contained in the Registration Statement, any preliminary
   prospectus or the Prospectus (or any amendment or supplement thereto), or
   arises out of or is based upon the omission or alleged omission to state
   therein a material fact required to be stated therein or necessary to make
   the statements therein not misleading, in each case to the extent, but only
   to the extent, that such untrue statement or alleged untrue statement or
   omission or alleged omission was made in the Registration Statement, any
   preliminary prospectus, the Prospectus (or any amendment or supplement
   thereto), in reliance upon and in conformity with written information
   furnished to the Company and the Selling Shareholders by the Representatives
   expressly for use therein; and to reimburse the Company, or any such
   director, officer, Selling Shareholder or controlling person for any and all
   expenses (including the reasonable fees and disbursements of counsel chosen
   by the Company and the Selling Shareholders) as such expenses are reasonably
   incurred by the Company, the Selling Shareholders or such controlling person
   in connection with investigating, defending, settling (pursuant to Section
   8(e)), compromising or paying any such loss, claim, damage, liability,
   expense or action.  The Company and each of the Selling Shareholders, hereby
   acknowledges that the only information that the Underwriters have furnished
   to the Company and the Selling Shareholders expressly for use in the
   Registration Statement, any preliminary prospectus or the Prospectus (or any
   amendment or supplement thereto) are the statements set forth (A) as the
   last two paragraphs on the inside front cover page of the Prospectus
   concerning stabilization and passive market making by the Underwriters and
   (B) in the table following the first paragraph and as the second and last
   paragraphs under the caption "Underwriting" in the Prospectus; and the
   Underwriters confirm that such statements are correct. The indemnity
   agreement set forth in this Section 8(c) shall be in addition to any
   liabilities that each Underwriter may otherwise have.

       (d)   NOTIFICATIONS AND OTHER INDEMNIFICATION PROCEDURES.

       Promptly after receipt by an indemnified party under this Section 8 of
   notice of the commencement of any action, such indemnified party will, if a
   claim in respect thereof is to be made against an indemnifying party under
   this Section 8, notify the indemnifying party in writing of the commencement
   thereof, but the omission so to notify the indemnifying party will not
   relieve it from any liability which it may have to any indemnified party
   under the indemnity agreement contained in this Section 8, for contribution
   under Section 9 or otherwise, except to the extent it is prejudiced as a
   proximate result of such failure.  In case any such action is brought
   against any indemnified party and such indemnified party seeks or intends to
   seek indemnity from an indemnifying party, the indemnifying party will be
   entitled


                                          26
<PAGE>

   to participate in, and, to the extent that it shall elect, jointly with all
   other indemnifying parties similarly notified, by written notice delivered
   to the indemnified party promptly after receiving the aforesaid notice from
   such indemnified party, to assume the defense thereof with counsel
   reasonably satisfactory to such indemnified party; PROVIDED, HOWEVER, if the
   defendants in any such action include both the indemnified party and the
   indemnifying party and the indemnified party shall have reasonably concluded
   that a conflict may arise between the positions of the indemnifying party
   and the indemnified party in conducting the defense of any such action or
   that there may be legal defenses available to it and/or other indemnified
   parties which are different from or additional to those available to the
   indemnifying party, the indemnified party or parties shall have the right to
   select separate counsel to assume such legal defenses and to otherwise
   participate in the defense of such action on behalf of such indemnified
   party or parties.  Upon receipt of notice from the indemnifying party to
   such indemnified party of such indemnifying party's election so to assume
   the defense of such action and approval by the indemnified party of counsel,
   the indemnifying party will not be liable to such indemnified party under
   this Section 8 for any legal or other expenses subsequently incurred by such
   indemnified party in connection with the defense thereof unless (i) the
   indemnified party shall have employed separate counsel in accordance with
   the proviso to the next preceding sentence (it being understood, however,
   that the indemnifying party shall not be liable for the expenses of more
   than one separate counsel (together with local counsel), approved by the
   indemnifying party (NMSI in the case of Section 8(b) and Section 9),
   representing the indemnified parties who are parties to such action) or
   (ii) the indemnifying party shall not have employed counsel satisfactory to
   the indemnified party to represent the indemnified party within a reasonable
   time after notice of commencement of the action, in each of which cases the
   fees and expenses of counsel shall be at the expense of the indemnifying
   party.

       (e)   SETTLEMENTS.

       The indemnifying party under this Section 8 shall not be liable for any
   settlement of any proceeding effected without its written consent, but if
   settled with such consent or if there be a final judgment for the plaintiff,
   the indemnifying party agrees to indemnify the indemnified party against any
   loss, claim, damage, liability or expense by reason of such settlement or
   judgment.  Notwithstanding the foregoing sentence, if at any time an
   indemnified party shall have requested an indemnifying party to reimburse
   the indemnified party for fees and expenses of counsel as contemplated by
   Section 8(d) hereof, the indemnifying party agrees that it shall be liable
   for any settlement of any proceeding effected without its written consent if
   (i) such settlement is entered into more than 30 days after receipt by such
   indemnifying party of the aforesaid request, (ii) such indemnifying party
   shall not have reimbursed the indemnified party in accordance with such
   request prior to the date of such settlement and (iii) the indemnified party
   gives the indemnifying party three business days prior notice of any
   proposed settlement.  In any event, no indemnifying party shall, without the
   prior written consent of the indemnified party, effect any settlement,
   compromise or consent to the entry of judgment in any pending or threatened
   action, suit or proceeding in respect of which any indemnified party is or
   could have been a party and indemnity was or could have been sought
   hereunder by such indemnified party, unless such settlement, compromise or
   consent includes an unconditional release of such indemnified party from all
   liability on claims that are the subject matter of such action, suit or
   proceeding.


                                          27

SECTION 9.  CONTRIBUTION.

     If the indemnification provided for in Section 8 is for any reason held to
be unavailable to or otherwise insufficient to hold harmless an indemnified
party in respect of any losses, claims, damages, liabilities or expenses
referred to therein, then (subject to the first sentence of Section 8(a)) each
indemnifying party shall contribute to the aggregate amount paid or payable by
such indemnified party, as incurred, as a result of any losses, claims, damages,
liabilities or expenses referred to therein in such proportion as is appropriate
to reflect the relative benefits received by the Company and the Selling
Shareholders, on the one hand, and the Underwriters, on the other hand, from the
offering of the Common Shares pursuant to this Agreement and the relative fault
of the Company and the Selling Shareholders, on the one hand, and the
Underwriters, on the other hand, in connection with the statements or omissions
or inaccuracies in the representations and warranties herein which resulted in
such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations.  The relative benefits received by the
Company and the Selling Shareholders, on the one hand, and the Underwriters, on
the other hand, in connection with the offering of the Common Shares pursuant to
this Agreement shall be deemed to be in the same respective proportions as the
total net proceeds from the offering of the Common Shares pursuant to this
Agreement (before deducting expenses) received by the Company and the Selling
Shareholders, and the total underwriting discount received by the Underwriters,
in each case as set forth on the front cover page of the Prospectus (or, if
Rule 434 under the Securities Act is used, the corresponding location on the
Term Sheet) bear to the aggregate initial public offering price of the Common
Shares as set forth on such cover.  The relative fault of the Company and the
Selling Shareholders, on the one hand, and the Underwriters, on the other hand,
shall be determined by reference to, among other things, whether any such untrue
or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact or any such inaccurate or alleged inaccurate
representation or warranty relates to information supplied by the Company or the
Selling Shareholders, on the one hand, or the Underwriters, on the other hand,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

     The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and expenses referred to above shall be deemed to include,
subject to the limitations set forth in Section 8(d), any reasonable legal or
other fees or expenses incurred by such party in connection with investigating
or defending any action or claim.  The provisions set forth in Section 8(d) with
respect to notice of commencement of any action shall apply if a claim for
contribution is to be made under this Section 9; PROVIDED, HOWEVER, that no
additional notice shall be required with respect to any action for which notice
has been given under Section 8(d) for purposes of indemnification.

     The Company, the Selling Shareholders and the Underwriters agree that it
would not be just and equitable if contribution pursuant to this Section 9 were
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 9.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.  The
Underwriters' obligations to contribute pursuant to this Section 9 are several,
and not joint, in proportion to their respective underwriting commitments as set
forth opposite their names in SCHEDULE A.  Each Selling Shareholder's obligation
to contribute


                                          28
<PAGE>

pursuant to this Section 9 are several, and not joint, in proportion to the net
proceeds to be received by such Selling Shareholder pursuant to the sale of
Common Shares hereunder.  For purposes of this Section 9, each officer and
employee of an Underwriter and each person, if any, who controls an Underwriter
within the meaning of the Securities Act and the Exchange Act shall have the
same rights to contribution as such Underwriter, and each director of the
Company, each officer of the Company who signed the Registration Statement, and
each person, if any, who controls the Company with the meaning of the Securities
Act and the Exchange Act shall have the same rights to contribution as the
Company.

SECTION 10.  DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITER.

     If, on the First Closing Date or the Second Closing Date, as the case may
be, any one or more of the several Underwriters shall fail or refuse to purchase
Common Shares that it or they have agreed to purchase hereunder on such date,
and the aggregate number of Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase does not exceed 10% of the
aggregate number of the Common Shares to be purchased on such date, the other
Underwriters shall be obligated, severally, in the proportions that the number
of Firm Common Shares set forth opposite their respective names on SCHEDULE A
bears to the aggregate number of Firm Common Shares set forth opposite the names
of all such non-defaulting Underwriters, or in such other proportions as may be
specified by the Representatives with the consent of the non-defaulting
Underwriters, to purchase the Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date.  If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the Underwriters shall fail or refuse to purchase Common Shares and the
aggregate number of Common Shares with respect to which such default occurs
exceeds 10% of the aggregate number of Common Shares to be purchased on such
date, and arrangements satisfactory to the Representatives and the Company for
the purchase of such Common Shares are not made within 48 hours after such
default, this Agreement shall terminate without liability of any party to any
other party (other than the defaulting Underwriter or Underwriters) except that
the provisions of Section 4, Section 8 and Section 9 shall at all times be
effective and shall survive such termination.  In any such case either the
Representatives or the Company shall have the right to postpone the First
Closing Date or the Second Closing Date, as the case may be, but in no event for
longer than seven days in order that the required changes, if any, to the
Registration Statement and the Prospectus or any other documents or arrangements
may be effected.

     As used in this Agreement, the term "Underwriter" shall be deemed to
include any person substituted for a defaulting Underwriter under this
Section 10.  Any action taken under this Section 10 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

SECTION 11.  TERMINATION OF THIS AGREEMENT.

     Prior to the First Closing Date this Agreement maybe terminated by the
Representatives by notice given to the Company and the Selling Shareholders if
at any time (i) trading or quotation in any of the Company's securities shall
have been suspended or limited by the Commission or by the Nasdaq Stock Market,
or trading in securities generally on either the Nasdaq Stock Market or the New
York Stock Exchange shall have been suspended or limited, or minimum or maximum
prices shall have been generally established on any of such stock exchanges by
the Commission or the NASD; (ii) a general banking moratorium shall have been
declared by any of federal, New York, Colorado or California authorities;
(iii) there shall have


                                          29
<PAGE>

occurred any outbreak or escalation of national or international hostilities or
any crisis or calamity, or any change in the United States or international
financial markets, or any substantial change or development involving a
prospective substantial change in United States' or international political,
financial or economic conditions, as in the judgment of the Representatives is
material and adverse and makes it impracticable to market the Common Shares in
the manner and on the terms described in the Prospectus or to enforce contracts
for the sale of securities; (iv) in the judgment of the Representatives there
shall have occurred any Material Adverse Change; or (v) the Company shall have
sustained a loss by strike, fire, flood, earthquake, accident or other calamity
of such character as in the judgment of the Representatives may interfere
materially with the conduct of the business and operations of the Company
regardless of whether or not such loss shall have been insured.  Any termination
pursuant to this Section 11 shall be without liability on the part of (a) the
Company or the Selling Shareholders to any Underwriter, except that the Company
and the Selling Shareholders shall be obligated to reimburse the expenses of the
Representatives and the Underwriters pursuant to Sections 4 and 6 hereof, (b)
any Underwriter to the Company or the Selling Shareholders, or (c) of any party
hereto to any other party except that the provisions of Section 8 and Section 9
shall at all times be effective and shall survive such termination.

SECTION 12.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY.

     The respective indemnities, agreements, representations, warranties and
other statements of the Company, of its officers, of the Selling Shareholders
and of the several Underwriters set forth in or made pursuant to this Agreement
will remain in full force and effect, regardless of any investigation made by or
on behalf of any Underwriter or the Company or any of its or their partners,
officers or directors or any controlling person, or the Selling Shareholders, as
the case may be, and will survive delivery of and payment for the Common Shares
sold hereunder and any termination of this Agreement.

each case located in the City and County of San Francisco (collectively, the
"Specified Courts"), and each party irrevocably submits to the exclusive

SECTION 17.  FAILURE OF ONE OR MORE OF THE SELLING SHAREHOLDERS TO SELL AND
             DELIVER COMMON SHARES.

     If one or more of the Selling Shareholders shall fail to sell and deliver
to the Underwriters the Common Shares to be sold and delivered by such Selling
Shareholders at the First Closing Date pursuant to this Agreement, then the
Underwriters may at their option, by written notice from the Representatives to
the Company and the Selling Shareholders, either (i) terminate this Agreement
without any liability on the part of any Underwriter or, except as provided in
Sections 4, 6, 8 and 9 hereof, the Company or the Selling Shareholders, or
(ii) purchase the shares which the Company and other Selling Shareholders have
agreed to sell and deliver in accordance with the terms hereof.  If one or more
of the Selling Shareholders shall fail to sell and deliver to the Underwriters
the Common Shares to be sold and delivered by such Selling Shareholders pursuant
to this Agreement at the First Closing Date or the Second Closing Date, then the
Underwriters shall have the right, by written notice from the Representatives to
the Company and the Selling Shareholders, to postpone the First Closing Date or
the Second Closing Date, as the case may be, but in no event for longer than
seven days in order that the required changes, if any, to the Registration
Statement and the Prospectus or any other documents or arrangements may be
effected.

SECTION 18.  GENERAL PROVISIONS.

     This Agreement constitutes the entire agreement of the parties to this
Agreement and supersedes all prior written or oral and all contemporaneous oral
agreements, understandings and negotiations with respect to the subject matter
hereof.  This Agreement may be executed in two or more counterparts, each one of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument.  This Agreement may not be amended or
modified unless in writing by all of the parties hereto, and no condition herein
(express or implied) may be waived unless waived in writing by each party whom
the condition is meant to benefit.  The Table of Contents and the Section
headings herein are for the convenience of the parties only and shall not affect
the construction or interpretation of this Agreement.

     Each of the parties hereto acknowledges that it is a sophisticated business
person who was adequately represented by counsel during negotiations regarding
the provisions hereof, including, without limitation, the indemnification
provisions of Section 8 and the contribution provisions of Section 9, and is
fully informed regarding said provisions.  Each of the parties hereto further
acknowledges that the provisions of Sections 8 and 9 hereto fairly allocate the
risks in light of the ability of the parties to investigate the Company, its
affairs and its business in order to assure that adequate disclosure has been
made in the Registration Statement, any preliminary prospectus and the

[THE FINAL OPINION IN DRAFT FORM WILL BE ATTACHED AS EXHIBIT A AT THE TIME THIS
AGREEMENT IS EXECUTED.]

          Opinion of counsel for the Company to be delivered pursuant to
Section 5(e) of the Underwriting Agreement.

          References to the Prospectus in this EXHIBIT A include any supplements
thereto at the Closing Date.

      (i)    The Company has been duly incorporated and is validly existing as
  a corporation in good standing under the laws of the State of Colorado.

      (ii)   The Company has corporate power and authority to own, lease and
  operate its properties and to conduct its business as described in the
  Prospectus and to enter into and perform its obligations under the
  Underwriting Agreement.

      (iii)  The Company is duly qualified as a foreign corporation to transact
  business and is in good standing in the States of Indiana, North Carolina,
  Texas and Wisconsin in each other jurisdiction in which such qualification is
  required, whether by reason of the ownership or leasing of property or the
  conduct of business, except for such jurisdictions (other than the States of
  Indiana, North Carolina, Texas and Wisconsin) where the failure to so qualify
  or to be in good standing would not, individually or in the aggregate, result
  in a Material Adverse Change.

      (iv)   Each significant subsidiary (as defined in Rule 405 under the
  Securities Act) has been duly incorporated and is validly existing as a
  corporation in good standing under the laws of the jurisdiction of its
  incorporation, has corporate power and authority to own, lease and operate
  its properties and to conduct its business as described in the Prospectus
  and, to the best knowledge of such counsel, is duly qualified as a foreign
  corporation to transact business and is in good standing in each jurisdiction
  in which such qualification is required, whether by reason of the ownership
  or leasing of property or the conduct of business, except for such
  jurisdictions where the failure to so qualify or to be in good standing would
  not, individually or in the aggregate, result in a Material Adverse Change.

      (v)    All of the issued and outstanding capital stock of each such
  significant subsidiary has been duly authorized and validly issued, is fully
  paid and non-assessable and is owned by the Company, directly or through
  subsidiaries, free and clear of any security interest, mortgage, pledge,
  lien, encumbrance or, to the best knowledge of such counsel, any pending or
  threatened claim.

      (vi)   The authorized, issued and outstanding capital stock of the
  Company (including the Common Stock) conform to the descriptions thereof set
  forth or incorporated by reference in the Prospectus.  All of the outstanding
  shares of Common Stock (including the shares of Common Stock owned by Selling
  Shareholders) have been duly authorized and validly issued, are fully paid
  and nonassessable and, to the best of such counsel's knowledge,


                                         A-1
<PAGE>

  have been issued in compliance with the registration and qualification
  requirements of federal and state securities laws.  The form of certificate
  used to evidence the Common Stock is in due and proper form and complies with
  all applicable requirements of the charter and by-laws of the Company and the
  General Corporation Law of the State of Colorado.  The description of the
  Company's stock option, stock bonus and other stock plans or arrangements,
  and the options or other rights granted and exercised thereunder, set forth
  in the Prospectus accurately and fairly presents the information required to
  be shown with respect to such plans, arrangements, options and rights.

      (vii)  No shareholder of the Company or any other person has any
  preemptive right, right of first refusal or other similar right to subscribe
  for or purchase securities of the Company arising (i) by operation of the
  charter or by-laws of the Company, (ii) or the General Corporation Law of the
  State of Colorado, or (iii) to the best knowledge of such counsel, otherwise.

      (viii) The Underwriting Agreement has been duly authorized, executed and
  delivered by, and is a valid and binding agreement of, the Company,
  enforceable in accordance with its terms, except as rights to indemnification
  thereunder may be limited by applicable law and except as the enforcement
  thereof may be limited by bankruptcy, insolvency, reorganization, moratorium
  or other similar laws relating to or affecting creditors' rights generally or
  by general equitable principles.

      (ix)   The Common Shares to be purchased by the Underwriters from the
  Company have been duly authorized for issuance and sale pursuant to the
  Underwriting Agreement and, when issued and delivered by the Company pursuant
  to the Underwriting Agreement against payment of the consideration set forth
  therein, will be validly issued, fully paid and nonassessable.

      (x)    Each of the Registration Statement and the Rule 462(b)
  Registration Statement, if any, has been declared effective by the Commission
  under the Securities Act.  To the best knowledge of such counsel, no stop
  order suspending the effectiveness of either of the Registration Statement or
  the Rule 462(b) Registration Statement, if any, has been issued under the
  Securities Act and no proceedings for such purpose have been instituted or
  are pending or are contemplated or threatened by the Commission.  Any
  required filing of the Prospectus and any supplement thereto pursuant to Rule
  424(b) under the Securities Act has been made in the manner and within the
  time period required by such Rule 424(b).

      (xi)   The Registration Statement, including any Rule 462(b) Registration
  Statement, the Prospectus, including any document incorporated by reference
  therein, and each amendment or supplement to the Registration Statement and
  the Prospectus including any document incorporated by reference therein, as
  of their respective effective or issue dates (other than the financial
  statements and supporting schedules included or incorporated by reference
  therein or in exhibits to or excluded from the Registration Statement, as to
  which no opinion need be rendered) comply as to form in all material respects
  with the applicable requirements of the Securities Act and the Exchange Act.

      (xii)  The Common Stock is listed on the Nasdaq National Market, and to
  the best knowledge of such counsel, the Company has taken no action designed
  to, or likely to have the effect of, terminating the registration of the
  Common Stock under the Exchange Act or delisting the Common Stock from the
  Nasdaq National Market nor has the Company


                                         A-2
<PAGE>

  received any notification that the Commission or the National Association of
  Securities Dealers LLC (the "NASD") is contemplating terminating such
  registration or listing.

      (xiii) The statements (i) in the Prospectus under the captions "Risk
  Factors--Risks Associated with Terms of Customer Contracts; --Shares Eligible
  for Future Sale; and --Effect of Certain Charter and Bylaw Provisions,"
  "Business--Customer Contracts," "Business--Intellectual Property," "Shares
  Eligible for Future Sale," and "Underwriting" and (ii) in Items 14 and 15 of
  the Registration Statement, insofar as such statements constitute matters of
  law, summaries of legal matters, the Company's charter or by-law provisions,
  documents or legal proceedings, or legal conclusions, has been reviewed by
  such counsel and fairly present and summarize, in all material respects, the
  matters referred to therein.

      (xiv)  To the best knowledge of such counsel, there are no legal or
  governmental actions, suits or proceedings pending or threatened which are
  required to be disclosed in the Registration Statement, other than those
  disclosed therein.

      (xv)   To the best knowledge of such counsel, there are no Existing
  Instruments required to be described or referred to in the Registration
  Statement or to be filed as exhibits thereto other than those described or
  referred to therein or filed or incorporated by reference as exhibits
  thereto; and the descriptions thereof and references thereto are correct in
  all material respects.

      (xvi)  No consent, approval, authorization or other order of, or
  registration or filing with, any court or other governmental authority or
  agency, is required for the Company's execution, delivery and performance of
  the Underwriting Agreement and consummation of the transactions contemplated
  thereby and by the Prospectus, except as required under the Securities Act,
  applicable state securities or blue sky laws and from the NASD.

      (xvii) The execution and delivery of the Underwriting Agreement by the
  Company and the performance by the Company of its obligations thereunder
  (other than performance by the Company of its obligations under the
  indemnification section of the Underwriting Agreement, as to which no opinion
  need be rendered) (i) have been duly authorized by all necessary corporate
  action on the part of the Company; (ii) will not result in any violation of
  the provisions of the charter or by-laws of the Company or any subsidiary;
  (iii) will not constitute a breach of, or Default under, or result in the
  creation or imposition of any lien, charge or encumbrance upon any property
  or assets of the Company or any of its subsidiaries pursuant to, [(A) LIST
  DEBT INSTRUMENTS] or (B) to the best knowledge of such counsel, any other
  material Existing Instrument; or (iv) to the best knowledge of such counsel,
  will not result in any violation of any law, administrative regulation or
  administrative or court decree applicable to the Company or any subsidiary.

      (xviii)     The Company is not, and after receipt of payment for the
  Common Shares will not be, an "investment company" within the meaning of
  Investment Company Act.

      (xix)  Except as disclosed in the Prospectus, to the best knowledge of
  such counsel, there are no persons with registration or other similar rights
  to have any equity or debt securities registered for sale under the
  Registration Statement or included in the offering contemplated by the
  Underwriting Agreement, other than the Selling Shareholders, except for such
  rights as have been duly and validly waived.


                                         A-3
<PAGE>

      (xx)   To the best knowledge of such counsel, neither the Company nor any
  subsidiary is in violation of its charter or by-laws or any law,
  administrative regulation or administrative or court decree applicable to the
  Company or any subsidiary or is in Default in the performance or observance
  of any obligation, agreement, covenant or condition contained in any material
  Existing Instrument, except in each such case for such violations or Defaults
  as would not, individually or in the aggregate, result in a Material Adverse
  Change.

      (xxi)  Each document filed pursuant to the Exchange Act (other than the
  financial statements and supporting schedules included therein, as to which
  no opinion need be rendered) and incorporated or deemed to be incorporated by
  reference in the Prospectus complied when so filed as to form in all material
  respects with the Exchange Act.

     In addition, such counsel shall state that they have participated in
conferences with officers and other representatives of the Company,
representatives of the independent public or certified public accountants for
the Company and with representatives of the Underwriters at which the contents
of the Registration Statement and the Prospectus, and any supplements or
amendments thereto, and related matters were discussed and, although such
counsel is not passing upon and does not assume any responsibility for the
accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectus (other than as specified above), and
any supplements or amendments thereto, on the basis of the foregoing, nothing
has come to their attention which would lead them to believe that either the
Registration Statement or any amendments thereto, at the time the Registration
Statement or such amendments became effective, contained an untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading or that the
Prospectus, as of its date or at the First Closing Date or the Second Closing
Date, as the case may be, contained an untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading (it being understood that such counsel need express no belief as to
the financial statements or schedules or other financial or statistical data
derived therefrom, included or incorporated by reference in the Registration
Statement or the Prospectus or any amendments or supplements thereto).

     In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the General
Corporation Law of the State of Delaware, the General Corporation Law of the
State of Colorado or the federal law of the United States, to the extent they
deem proper and specified in such opinion, upon the opinion (which shall be
dated the First Closing Date or the Second Closing Date, as the case may be,
shall be satisfactory in form and substance to the Underwriters, shall expressly
state that the Underwriters may rely on such opinion as if it were addressed to
them and shall be furnished to the Representatives) of other counsel of good
standing whom they believe to be reliable and who are satisfactory to counsel
for the Underwriters; PROVIDED, HOWEVER, that such counsel shall further state
that they believe that they and the Underwriters are justified in relying upon
such opinion of other counsel, and (B) as to matters of fact, to the extent they
deem proper, on certificates of responsible officers of the Company and public
officials.

THE FINAL OPINION IN DRAFT FORM WILL BE ATTACHED AS EXHIBIT B AT THE TIME THIS
AGREEMENT IS EXECUTED.


     The opinion of such counsel pursuant to Section 5(h) shall be rendered to
the Representatives at the request of the Company and shall so state therein.
References to the Prospectus in this EXHIBIT B include any supplements thereto
at the Closing Date.

      (i)    The Underwriting Agreement has been duly authorized, executed and
  delivered by or on behalf of, and is a valid and binding agreement of, such
  Selling Shareholder, enforceable in accordance with its terms, except as
  rights to indemnification and contribution thereunder may be limited by
  applicable law and except as the enforcement thereof may be limited by
  bankruptcy, insolvency, reorganization, moratorium or other similar laws
  relating to or affecting creditors' rights generally or by general equitable
  principles.

      (ii)   The execution and delivery by such Selling Shareholder of, and the
  performance by such Selling Shareholder of its obligations under, the
  Underwriting Agreement, Custody Agreement and Power of Attorney will not to
  the best of such counsel's knowledge, (a) violate or contravene any provision
  of applicable law or regulation, or (b) violate, result in a breach of or
  constitute a default under the terms of any other agreement or instrument to
  which such Selling Shareholder is a party or by which it is bound, or any
  judgment, order or decree applicable to such Selling Shareholder of any
  court, regulatory body, administrative agency, governmental body or
  arbitrator having jurisdiction over such Selling Shareholder.

      (iii)  Such Selling Shareholder has the legal right and power to enter
  into the Underwriting Agreement, Custody Agreement and Power of Attorney, to
  sell, transfer and deliver all of the Common Shares which may sold by such
  Selling Shareholder under the Underwriting Agreement and to comply with its
  other obligations under the Underwriting Agreement, Custody Agreement and
  Power of Attorney.

      (iv)   Each of the Custody Agreement and Power of Attorney of such
  Selling Shareholder has been duly authorized, executed and delivered by such
  Selling Shareholder and is a valid and binding agreement of such Selling
  Shareholder, enforceable in accordance with its terms, except as rights to
  indemnification thereunder may be limited by applicable law and except as the
  enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
  moratorium or other similar laws relating to or affecting creditors' rights
  generally or by general equitable principles.


                                         B-1
<PAGE>

      (v)    Assuming that the Underwriters purchase the Common Shares which
  are sold by such Selling Shareholder pursuant to the Underwriting Agreement
  for value, in good faith and without notice of any adverse claim, the
  delivery of such Common Shares pursuant to the Underwriting Agreement will
  pass good and valid title to such Common Shares, free and clear of any
  security interest, mortgage, pledge, lieu encumbrance or other claim.

      (vi)   To the best of such counsel's knowledge, no consent, approval,
  authorization or other order of, or registration or filing with, any court or
  governmental authority or agency, is required for the consummation by such
  Selling Shareholder of the transactions contemplated in the Underwriting
  Agreement, except as required under the Securities Act, applicable state
  securities or blue sky laws, and from the NASD.

     In rendering such opinion, such counsel may rely as to matters of fact, to
the extent they deem proper, on certificates of the Selling Shareholders and
public officials
