ITEM 1.  BUSINESS

The Company

GENERAL

         Scientific Software-Intercomp, Inc. (the "Company") develops and
markets sophisticated software for the development and production and pipeline
and surface facilities areas of the worldwide oil and gas industry and for
graphical user interface applications.  The Company's computer-aided production
("CAP") software provides oil and gas industry professionals with a
comprehensive set of powerful, cost-effective tools that describe, simulate and
predict oil and gas production from reservoirs under alternative simulated
development plans.  These predictions are used to determine optimal development
plans for maximizing recoverable reserves, thereby reducing oil and gas finding
costs per equivalent barrel.  The Company's pipeline and surface facilities
software simulates and monitors oil and gas pipelines and surface facilities
for various uses including engineering design, leak detection, optimization of
transportation efficiency and pipeline dispatcher training.  Its graphical user
interface ("GUI") software, Sammi, facilitates the creation of customized
graphical interfaces and the display of large quantities of static and real
time data from multiple sources primarily for the oil and gas, aerospace,
process control and manufacturing industries.  The Company provides consulting
and technical support services in each of these areas.

         Since its formation in 1968, the Company believes that it has
established a reputation for technical excellence of its software products and
consulting services in reservoir description, simulation and monitoring.  In
the late 1980s, the Company recognized the need to provide an integrated system
of CAP products that could be more broadly utilized by the oil and gas
industry.  Also, the availability of increasingly powerful and affordable
computers enables the Company's CAP software products to operate on UNIX-based
workstations and personal computers, and more recently on DOS/Windows-based
personal computers, with capabilities historically available only on mainframe
computers.  The Company has developed Petroleum WorkBench, an integrated
software system that allows effective access to five of the Company's high
technology stand-alone CAP products.  It is expected that future versions of
Petroleum WorkBench will increase the technical breadth of this software
package.  These developments have had the effect of significantly expanding the
market for the Company's CAP software products from its historical market of
research experts and technical specialists using mainframe computers to include
non-expert industry professionals, such as petroleum engineers and geologists,
using workstations or personal computers.  These developments have also
increased the functionality and ease of use of the Company's CAP products to
the oil and gas industry by lowering hardware costs and reducing the need to
utilize these experts in order to take advantage of the Company's technology.

         The Company's objective is to be a leading provider of high technology
computing solutions and quality consulting services in each of its industry
areas.  The Company's long range goal is to offer a fully integrated set of
software products that will permit non-expert professionals to describe,
simulate, monitor and manage the complete range of reservoir development and
production activities and oil and gas transmission and storage activities of
oil and gas fields from personal computers.  The  Company believes that its
current products encompass nearly all technologies necessary to accomplish its
objective of integrated computer-aided field management capabilities.

         The Company's executive offices are located at 1801 California Street,
Suite 295, Denver, Colorado 80202 and its telephone number is (303) 292-1111.

COMPLETION OF PUBLIC OFFERING OF COMMON STOCK

         On June 30, 1994, the Company sold 2.0 million newly issued shares of
common stock in a public offering from which the Company received net proceeds
of $8.1 million, net of related costs of





                                      -2-
<PAGE>   3
approximately $270,000.  The Company used the proceeds from the public offering
to repay its bank indebtedness of $5.1 million, to reduce accounts payable, and
to increase working capital.

         In July 1994 the underwriters of the public offering exercised an
overallotment option, resulting in the sale by the Company of 383,000
additional newly issued shares of common stock, from which the Company received
net proceeds of approximately $1.6 million.

         Simultaneously with completion of the public offering, Renaissance
Capital Partners II, Ltd. ("Renaissance") converted $1.75 million in principal
amount of convertible debentures (see Note 3 to Consolidated Financial
Statements) into 653,846 shares of common stock, which Renaissance sold in the
public offering.  As a result of the Renaissance conversion, the Company
reduced paid-in capital by $119,000 for unamortized debt issuance costs related
to the converted debentures.

HISTORY

         The Company, a Colorado corporation, was formed in 1968 and, since
that time, has developed and marketed sophisticated applications software
together with computer-related consulting services, principally for reservoir
description and reservoir and pipeline simulation.  These technologically
complex products have been, and continue to be, sold primarily to major
multinational and large independent oil companies for use by research experts
and technical specialists.  The Company believes that it has established a
reputation for technical excellence of its software products and consulting
services in reservoir description, simulation and monitoring.

         In June 1983, the Company acquired Intercomp Resource Development and
Engineering, Inc. ("IRDE"), which had developed additional software products
for reservoir simulation.  In January 1984, the Company acquired CRC Bethany
International, Inc. ("CRC"), a wholly owned subsidiary of Crutcher Resources
Corporation.  The acquisition of CRC provided the Company with software systems
that modeled real-time data collected and stored by Supervisory Control and
Data Acquisition ("SCADA") systems installed on oil and gas pipelines.

         Several trends, including lower oil and gas prices, are driving the
oil and gas industry to reduce the risk and cost, and to increase the
effectiveness, of development and production activities.  This has led many
energy companies to reduce budgets, including a decline in the employment of
research and technical experts in the various petroleum industry disciplines,
in favor of non-expert industry professionals.  The Company recognized the need
to provide an integrated system of CAP products for use by these non-experts.
By 1991, the Company had developed Petroleum WorkBench which provides the
industry with broader access to sophisticated engineering solutions.
Management believes that these developments, coupled with the availability of
increasingly powerful and affordable workstations and personal computers, has
opened a significant market for Petroleum WorkBench.

STRATEGY

         The Company's strategy is to provide complete, high technology,
computing solutions and other services for the development and production of
oil and gas reservoirs and the pipeline transportation of oil and gas.  The
Company executes this strategy in the following ways:

         INTEGRATION OF HIGH TECHNOLOGY PRODUCTS.  Since its formation, the
Company has developed a series of software products designed to describe,
simulate and monitor oil and gas reservoirs, simulate and monitor oil and gas
pipelines and surface facilities, and develop graphical user interfaces.  These
products cover nearly all technologies needed to simulate, study, optimally
develop and monitor oil and gas reservoirs and oil and gas pipelines.  These
products also include nearly all facets of technology necessary for field
management and field monitoring in the oil and gas industry.  The Company has
begun integrating these products, which increase the functionality and ease of
use of the high technology solutions provided by the Company's products.





                                      -3-
<PAGE>   4
         The initial integrated product, Petroleum WorkBench, includes five of
the Company's major stand-alone CAP products.  It is the Company's intention to
continue integrating its products until the full breadth of the Company's
technology is included within one integrated, easily accessible product that
will allow a single non-expert professional to work in multiple disciplines,
using the same database and applications software.

         EXPANSION OF MARKETING EFFORTS AND CUSTOMER BASE.  The Company
believes that, by continuing the integration and accessibility of its software,
the market for its CAP software and related consulting services can be expanded
to increase sales to non-expert industry professionals.  The Company intends to
intensify its marketing efforts to this larger market, in addition to
continuing to market its products to its established customer base of expert
users generally employed by major multinational and large independent oil
companies.

         The Company also intends to expand its customer base in the pipeline
and surface facilities market through the testing and possible introduction in
1996 of a new leak detection product for smaller pipelines.  Finally, the
Company intends to intensify its marketing efforts for Sammi to customers
outside the oil and gas industry.

         COMPLETE RANGE OF SERVICES.  The Company believes that offering a
complete range of consulting and training services is a critical component of
its business and it intends to continue enhancing and expanding the range of
consulting services to meet the growing requirements of its customers.  The
Company also believes that providing sophisticated and comprehensive consulting
services promotes and advances acceptance and awareness of its products.

         TECHNICAL LEADERSHIP.  The Company intends to continue developing new
software products and enhancing existing software products, both internally and
through jointly-funded development efforts, to respond to developments by
competitors and changes in technology.  The Company also intends to continue to
attract and retain highly-skilled professionals in computer software
programming and various petroleum industry disciplines in order to provide for
the development and enhancement of its products and services.  Finally, the
Company intends to continue to evaluate, and, if attractive, acquire or license
products and technologies which it believes are important to achieving its
strategy.

PRODUCTS, SERVICES AND CUSTOMERS

CAP PRODUCTS AND SERVICES

         The Company's CAP products and related consulting services address the
development and production areas of reservoir description and simulation.  The
Company's reservoir description products provide for the analysis of well logs
and core and 3-D seismic data, analysis of pressure and performance of wells
and mapping and analysis of the basic geology and reservoir rock parameters.
Reservoir description data is then input into mathematical reservoir simulators
offered by the Company to predict future production performance under various
simulated development scenarios after matching historical performance.  Use of
reservoir simulation provides more accurate forecasts of oil and gas recovery
and assists in the determination of how reservoirs should be optimally
developed.  The primary CAP products being marketed by the Company are:

         LOGCALC (well log analysis).  Used to calculate rock and fluid
properties around a wellbore from well logs in order to determine the presence
and quantities of hydrocarbons.

         INTERPRET/2 (well test analysis).  Used to analyze pressure and flow
tests of a well to predict reservoir flow capability and other formation
parameters such as the location of barriers in the reservoir.





                                      -4-
<PAGE>   5
         WPM (well productivity model).  Used to analyze and simulate the
productivity of a well under various alternative completion practices, such as
hydraulic fracturing and artificial lift, so that the optimum economics for the
well can be achieved.

         PVT (pressure-volume-temperature correlations for hydrocarbon fluids).
Used to analyze laboratory tests of oil and gas samples gathered from a
reservoir to determine the accuracy of the data and to construct equations for
use of the data.

         SimBest II (reservoir simulator for oil, water and gas).  Used to
model the behavior of an oil and gas reservoir in order to predict the results
of various types of reservoir development options, such as in-fill drilling,
water floods and gas injection, in order to determine the optimal development
plan for the reservoir.  The simulator calculates the flow of oil, water and
gas in three dimensions through a complex reservoir, including the flow through
the wellbores to the surface.

         COMP III, COMP 4 (compositional reservoir simulators for oil, water
and gas).  Used when the complex fluid behavior in the reservoir requires that
oil and gas be defined more precisely by their molecular components such as
methane, ethane and propane.  This simulator is most often used to simulate and
determine the optimum development of gas condensate reservoirs and oil
reservoirs undergoing high pressure gas injection.

         THERM (thermal reservoir simulator).  Used when modeling thermal
enhanced oil recovery processes such as steam injection and in-situ combustion
and is the most complex simulator because it also includes mathematical
simulation of such thermodynamic factors as combustion reaction kinetics.  This
simulator is used to predict optimum recovery using thermal enhanced recovery
processes for reservoir development.

         SimEase (interactive pre/post processor for the Company's reservoir
simulators).  Used to prepare data easily for input to the Company's reservoir
simulators and to view the results in color.  This software includes such
displays as color 3-D and 4-D (showing the passage of time) maps and simulated
color visualizations of fluids flowing through the reservoir.

         AHM (adaptive history matching system for use with reservoir
simulators).  Used to help match a reservoir's historical production of oil,
gas and water at various pressures.  A final calibrated (history matched) model
can then be used to simulate future production under various hypothetical
operating scenarios.

         PETROLEUM WORKBENCH (an integrated set of high technology products for
reservoir management).  This integrated set of products is used to perform
reservoir description, simulation and monitoring on a workstation or personal
computer.  Either an expert or non-expert professional can use this integrated
set of products to select optimum reservoir development plans using the highest
technology more quickly and efficiently than with non-integrated and
individually designed products.  The current version of Petroleum WorkBench
includes Logcalc, Interpret/2, SimBest II, parts of SimEase and PDA (the
Company's production data analysis system), plus various display capabilities
including mapping and cross-sections.  The Company's strategy for development
of Petroleum WorkBench includes making the Company's technology accessible to a
much larger market of non-expert professionals.  Petroleum WorkBench is also a
first step toward the future integration of the Company's other products to
encompass all technologies necessary to develop and manage oil and gas fields.

         Petroleum WorkBench was originally developed for the UNIX operating
system because of the size and complexity of the code, the graphics and the
need for networking with other desktop computers.  These capabilities are now
available on the existing DOS/Windows operating systems.

         In addition, the Company has a number of other CAP products including
PDA (production data analysis), PROBE (probability analysis for geoscientists),
PERMPROBE (statistical reservoir





                                      -5-
<PAGE>   6
permeability analysis), GEOPROBE (statistical reservoir geology analysis),
EORPM (enhanced oil recovery prediction models), CHEMFLOOD (chemical flooding
reservoir simulator), N-Hance (enhanced recovery reservoir simulator), OMEGA
(gas storage reservoir simulator), OMNET (reservoir simulator for multiple gas
storage reservoirs and pipelines), MATBAL (material balance reservoir
simulator), VFLOW (wellbore vertical flow simulator), IPS (investment planning
system), and GUESS (general uncertainty economic simulator).

         The Company also provides consulting, including training, on the use
and actual application of the Company's products and technology to a client's
reservoir management problems.  The Company provides consulting services in the
areas of geophysics, geology, petrophysics, reservoir engineering and
production and completion engineering.  The Company has designed cost-effective
exploitation methods, production and injection operations, and enhanced oil
recovery schemes.  The Company also has performed reserve evaluations and
special simulation techniques for artificial lift, horizontal drilling and
massive hydraulic fracturing.  In addition, the Company has designed
development plans of an entire oil field, including the operation and
monitoring of well and reservoir performance.

         Customers include major international oil companies such as Amoco,
British Petroleum, Mobil Oil, Phillips Petroleum, Royal Dutch Shell, Texaco and
Unocal; independent oil and gas companies such as Amerada Hess, Meridian Oil
and Pennzoil; and domestic and foreign governmental agencies and
government-sponsored companies such as the United States Department of Energy
and PEMEX.

PIPELINE AND SURFACE FACILITIES PRODUCTS, SERVICES AND CUSTOMERS

         The Company's software and related services for the pipeline and
surface facilities area simulate and monitor oil and gas pipelines and surface
facilities, such as compressor stations, tank farms and pumping stations, for
uses including engineering design, leak detection, optimization of
transportation efficiency and pipeline dispatcher training.  The systems are
used in either an "on-line" or "off-line" mode.  In the on-line mode, data is
continuously collected by a SCADA system from various points along a pipeline,
or from surface facilities, and used by the software for simulation and
monitoring purposes.  In the off-line mode, real-time data is not used and is
replaced by user-provided data for engineering or training purposes.  The
Company's historical focus in this area has been on providing simulation and
monitoring software to operators of large and complex pipelines and surface
facilities.  The current focus of the Company in this area is to develop and
market a standardized and modular system that is cost-effective for smaller
pipeline systems and to expand the types of facilities that utilize these
products.  The primary software products being marketed by the Company in this
area include:

         TGNET (transient gas pipeline network simulator).  Used off-line by
pipeline engineers to study portions of gas pipeline networks in order to
simulate the design and operation of the pipeline system.

         TLNET (transient liquid pipeline network simulator).  Like TGNET, used
off-line for liquid pipeline design and operations studies.

         MNET (multiphase pipeline network steady state simulator).  Like
TGNET, used off-line for pipeline design and operations studies for the
simultaneous flow of oil, gas and/or water.

         INTERACT (interactive pipeline network simulators).  Used by pipeline
engineers to plan future flows and to train pipeline dispatchers.  INTERACT is
comprised of three separate software products for gas, liquid and multiphase
pipeline flow and can be operated either on-line using real-time data or
off-line using historical pipeline operating data.

         PIPELINE MONITOR (leak detection system for intermediate complexity
pipeline networks).  Used continuously by the pipeline operating staff to
detect leaks and to manage pipeline operations with versions available for both
oil and gas pipelines.





                                      -6-
<PAGE>   7
         ON-LINE SYSTEM (pipeline leak detection and operating efficiency
software modules).  A series of software modules that can be integrated to
provide leak detection plus additional options such as product batch tracking
in liquid systems and compressor utilization for complex gas pipeline networks.
The software operates continuously, often with full backup computers, to manage
pipeline operations.

         In addition to the products described above, the Company has various
specialty software products such as HOT (simulation of heated pipelines) and
DYNAFLEX (pipeline stress analysis).

         The Company has also developed a prototype system for low cost leak
detection that can be easily installed on a single pipe.  Offline testing with
real data has been successful and field testing is expected in the first half
of 1996.  If successful, this system will address the much larger market of all
pipeline segments.

         The Company also provides consulting, including training, as required
by customers who use the technology and/or the products.  Training is provided
for both the use of the Company's software and to train dispatchers to handle
pipeline operational problems such as leaks and product batch tracking.  A
typical consulting project would be to configure the customer's actual pipeline
and surface facilities field data that describes the pipeline network, ensure
that the data accurately describes the field operations and then install and
test the data running in configuration with the Company's product at the
customer's site.

         Customers in this area include companies such as Tenneco Gas, Brooklyn
Union Gas, Alyeska Pipeline, Pacific Gas & Electric and Statoil; SCADA vendors
such as Valmet Automation and Asea Brown Boveri (ABB); and domestic and foreign
governmental agencies and government-sponsored companies such as the United
States Department of Transportation and Saudi ARAMCO.

GRAPHICAL USER INTERFACE PRODUCTS, SERVICES AND CUSTOMERS

         The Company's graphical user interface ("GUI") software product,
Sammi, facilitates the creation of customized graphical interfaces and displays
large quantities of static and real-time data from multiple sources.  Sammi
permits the creation of these customized graphical interfaces without the need
for extensive software code development.  The base technology for Sammi was
originally designed to provide for the development of real-time pipeline
displays but was found to have major applications in other markets such as
process control, transportation, aerospace and manufacturing.  The Company's
main products in this area are:

         Sammi (a GUI software toolkit).  Used to develop color display screens
and to connect the graphical image on the screen with a static or real-time
data stream.  In operational mode, Sammi processes and displays the data as
requested by the operator.

         SDK (Sammi development kit).  An open version of Sammi that enables
users to input graphical applications from other tool kits and to develop their
own graphic applications.

         GUI consulting is focused primarily on building graphical display
items to meet customer needs for specific applications and in assisting the
customer in using the Company's GUI products.  The Company also provides
training schools in the use of its products.

         Sammi is used in the aerospace, process control-manufacturing, and
transportation industries  and is suitable for other applications requiring
graphical display of large quantities of mission-critical real-time or
database-resident information.  Kinesix' major customers include NASA sites
(Johnson Space Center, Goddard, and Marshall), the U.S. Air Force, Loral,
Siemens, ABB, IBM, Hughes, Arco, Bristol Babcock, and Harris.

RESEARCH AND DEVELOPMENT

         The Company is committed to the continued enhancement of its petroleum
industry and GUI software and to the development of software and services
having new or related applications.  The Company's objective is to develop
products that are considered to be high quality and technically advanced and
that are capable of dominating their major market areas.

         In the CAP area, enhancement of Petroleum WorkBench will continue over
the next year with a new reservoir description module, addition of the Well
Productivity Model and updates to the other modules.  A new version of SimBest
is also expected to be released in 1996.  Further, enhancements are also
expected to most other CAP stand-alone products.

         In the pipeline and surface facilities area, new versions of all
off-line products are expected to be released in 1996 with easier-to-use
graphical interfaces.  The Company also is developing new software that is
expected to assist in the reduction of the cost of gas used for compression,
one of the major operating costs of gas pipelines.  Additional enhancements are
also expected to all the other stand-alone products in this area.

         In the GUI area, Kinesix announced its release of Sammi 3.0 in April
1994 and introduced an advanced tool, the Sammi Development Kit (SDK) at the
same time.  For the first time, Sammi's users were able to import third party
or custom graphics code into Sammi's high performance run-time framework.
Plans for 1996 include a new Format Editor and Microsoft Windows (NT and Win95)
versions of Sammi.

         During the years ended December 31, 1994, 1993 and 1992, the Company
spent $6.1 million, $5.5 million, and $6.9 million, respectively, for
development of new products and the improvement and enhancement of existing
products.  The number of employees and consultants engaged on a full or part
time basis in software development was 62 in 1994, 75 in 1993, and 73 in 1992.

         Management believes that the major development costs for the initial
versions of the Company's new products have been incurred and the Company is
well positioned to capitalize on the markets for these products.

Atlanta, Georgia; Dallas, Texas; northern California; and in Kuala Lumpur and
Abu Dhabi.  Local sales agents are utilized principally in third world
countries if local representation is necessary or appropriate.  The Company
markets certain of its products through resellers and local agents in certain
foreign countries.

         The Company provides installation and product training, on-site
consulting and 24-hour telephone availability of systems and technical experts
as part of its customer support services.

BACKLOG

         The Company's backlog at December 31, 1994 and 1993, was $8.8 million
and $10.6 million, respectively.

COMPETITION

         The market for most of the products and services offered by the
Company is highly competitive, although the number of competitors generally is
limited.  Certain of the Company's competitors have substantially greater
marketing and financial resources than the Company, although management
believes the Company's senior management and technical staff compare favorably
with those of its competitors.

         The principal competitive factors faced by the Company are product
functionality and performance, product price in relation to performance and
consulting and customer support services.  Management also believes that the
Company competes effectively due to its broad product line, large customer base
and reputation for quality products and expert services.  However, sales of the
Company's products and services would be adversely affected should competitors
introduce new products with better functionality, performance, price or other
competitive characteristics.

         The principal competitors in the licensing and sale of development and
production software are Intera ECL Petroleum Technologies, a subsidiary of
Intera Information Technologies Corporation, which markets a black oil and
compositional simulator, and Integrated Technologies, a division of Western
Atlas International, which markets a line of reservoir simulators.

         The competition in the licensing and sale of pipeline and surface
facilities software is fragmented with individual companies often marketing
only one or two products. Significant competitors in software licensing and
supply of related services of real time, on-line products in the leak detection
and real-time modeling areas are Stoner and Associates and Lic Consult.

         In the GUI market, the principal competitor is V.I. Corporation which
markets a series of products which, taken as a whole, compete with Sammi.  The
Company also competes with S.L. Corporation and various small companies that
market products having portions of the functionality of Sammi.

</TABLE>


         Revenue derived from foreign sources amounted to $18.2 million (65% of
total revenue), $18.5 million (61% of total revenue), and $17.1 million (59% of
total revenue), in 1994, 1993, and 1992, respectively.  The significant levels
of foreign revenue resulted from continued unfavorable economic conditions in
the domestic petroleum industry and continued penetration of new international
markets as a result of strategic marketing efforts in these areas.  Foreign
revenue is subject to a number of factors such as political instability,
changes in protective tariffs, tax policies, and export-import controls.  See
Note 7 to Consolidated Financial Statements for the Company's United States
export revenue and selected financial data of foreign subsidiaries.

         Much of the Company's business is conducted with large, established
U.S. and foreign companies (sometimes acting as government contractors),
governments and national petroleum companies of foreign governments.
Qualifying foreign receivables are insured, subject to a deductible loss
amount, under an insurance policy with the Foreign Credit Insurance
Association, an agency of the United States Export-Import Bank.  The Company
performs credit evaluations when considered necessary and generally does not
require collateral.

*  Less than 1%.

         During 1994, approximately 450 customers utilized the Company's
software products and related services, the loss of any one of which would not
have a material adverse effect on the Company's business.  During 1994, 1993,
and 1992, the Company generated $1.2 million, $2.0 million, and $2.0 million,
which were 4%,  6%, and 7%, respectively, of its total revenue from contracts
to perform reservoir engineering, geological studies, and petrophysical
analysis at the Naval Petroleum Reserves in California.  Revenue from this
project may decrease in the future.

PROPRIETARY RIGHTS

         The Company has protected its proprietary computer software by
restricting access to the underlying source code through technical means and by
requiring its customers to enter into licensing arrangements that are
protective of the Company's intellectual property rights in such software.  For
enforcement of its rights in the software, the Company relies upon laws
relating to trade secrets and the misappropriation of confidential business
information, as well as unfair competition laws, which are generally recognized
in both state and international judicial proceedings.  Additionally, the
Company obtains federal and international protection of its computer software
through federal copyright and the international copyright protection afforded
by the Berne Convention with reciprocal copyright protection in over 75
countries.  To date, the Company has not sought to patent any of its computer
software.  While the Company does not rule out obtaining patent protection for
computer software at some future time, the present procedure for obtaining
patent protection would require the Company to secure a patent in the United
States and all foreign countries where the software might be utilized, even
though the patentability of software in some foreign countries remains
questionable and in the process of patenting the software in the United States
the Company would be required to fully disclose the source code to the public
through its patent application.

         In addition, the Company requires all employees and consultants who
have access to its proprietary information and software to execute
confidentiality agreements.

EMPLOYEES

         As of January 31, 1996, the Company employed 149 persons full-time in
all locations, plus several part-time technical consultants as required to
complete project work.

ITEM 3.  LEGAL PROCEEDINGS

         To the knowledge of management, the only claim pending or threatened
against the Company or any of its subsidiaries which individually or
collectively could have a material adverse effect upon the Company or its
financial condition is the following:

         Marshall Wolf, on his behalf and on behalf of all others similarly
situated vs. E. A. Breitenbach, R. J.  Hottovy, Jimmy L. Duckworth, and
Scientific Software-Intercomp, Inc.  On October 5, 1995, a claim was filed in
the United States District Court for the District of Colorado alleging that the
Defendants, who include the President and Chief Executive Officer of the
Company, its Chief Financial Officer and a former Executive Vice President,
violated Section 10(b) of the Securities Exchange Act of 1934 and Rule 10(b)-5
promulgated thereunder in issuing financial reports for the first three
quarters of the Company's 1994 fiscal year which failed to comply with
generally accepted accounting principles with respect to revenues recognized
from the Company's contracts with value added resellers.  The Plaintiff seeks
to have the Court determine that the lawsuit constitutes a proper class action
on behalf of all persons who purchased stock of the Company during the period
from May 30, 1994 through July 10, 1995, with certain exclusions.  The
Company's independent auditors, Ehrhardt Keefe Steiner & Hottman PC, has issued
a report to the Company that the revenues from such contracts were recognized
in accordance with generally accepted accounting principles with the exception
of a $70,000 overstatement of revenue in the first quarter of 1994 which
exception they have concluded was immaterial assuming that the remaining
elements of such quarterly report were in accordance with generally accepted
accounting principles.  Based thereon, it is the opinion of the Company's
counsel that the claim is without merit and it is the intention of the Company
and the other Defendants to vigorously defend the claim.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         In the fourth quarter of 1994, the Company's shareholders voted in
favor of an increase in the number of authorized shares of common stock from
10,000,000 shares to 25,000,000 shares.  Following is an accounting of the
votes of the shareholders:

         RESULTS OF OPERATIONS

GENERAL

         The Company develops and markets sophisticated software for the
development and production and pipeline and surface facilities areas of the
worldwide oil and gas industry and for graphical user interface applications.

         The following discussion is management's assessment of the Company's
historical financial performance and condition.  This discussion should be read
in conjunction with the Consolidated Financial Statements of the Company and
the related Notes thereto.

         The Company recognizes software license revenue on delivery and
recognizes maintenance revenue on a straight-line basis over the term of the
contract.  Certain combined software and service contracts are accounted for
using the percentage of completion method with contract revenue recognized
based on: (a) value-added output measures of progress for the software portion
of the contract after meeting certain specified contractual criteria, and
having used the installed software in completing specifications for the
engineering services on the project, which have been accepted by the client,
and (b) input measures of work performed on an hours-to-hours basis for the
services portion of the contract.  Fixed-price contract revenue is recognized
using the percentage of completion method, calculated on the ratio of labor
hours incurred to total projected labor hours.  Losses on contracts accounted
for using the percentage of completion method are recognized at the time they
are identified.  See Note 1 to the Company's Consolidated Financial Statements.

         The Company capitalizes qualifying costs incurred in developing and
enhancing its software products in accordance with FASB Statement 86.  The
Company amortizes the capitalized software development costs of its stand-alone
software products and related enhancements over a 13-year period.  The
capitalized software development costs of Petroleum WorkBench and Sammi are
amortized over a seven-year period.  See Note 1 to the Company's Consolidated
Financial Statements and "Computer Software Research and Development" below.

LIQUIDITY AND CAPITAL RESOURCES

         OVERALL FINANCIAL POSITION.  The liquidity and financial condition of
the Company improved significantly during 1994 as a result of the sale of
common stock in the June 1994 public offering and other capital transactions
described below.  At December 31, 1994, the Company's working capital ratio was
1.4 to 1, based on current assets of $12.7 million and current liabilities of
$9.2 million.  The Company's working capital ratio at December 31, 1993, was
1.39 to 1.  Total stockholders' equity increased to $28.4 million at December
31, 1994, from $20.5 million at December 31, 1993.

         At December 31, 1993 and 1992, the Company had positive working
capital of $4.4 million and $1.9 million, respectively.  During 1992 and 1993,
the Company undertook a series of steps to increase its financial flexibility
and liquidity.  In September 1992, the Company issued a $2.5 million 7-year
convertible debenture to Renaissance Capital Partners II, Ltd. ("Renaissance")
and in September 1993 issued a $1.0 million 7-year convertible debenture to
Renaissance.  See Note 3 to the Consolidated Financial Statements.  In January
1994, the Company extended the maturity of its revolving credit facility, and
the related guarantee issued by the United States Export-Import Bank, through
January 1995.  The $5.0 million outstanding under the Company's revolving
credit facility at December 31, 1993, was classified as a long-term liability.

         The Company believes that its improved financial condition and
liquidity will enable increased efforts aimed at further market penetration of
its new WorkBench and Sammi products, as well as increased efforts aimed at
further market penetration of its traditional products and services.

<PAGE>   19
         The Company's working capital and cash requirements will continue to
be influenced by the level of software research and development costs.  During
the years ended December 31, 1994 and 1993, the Company reduced the level of
software research and development costs, in the aggregate and as a percentage
of total costs incurred (excluding software amortization), to $6.4 million and
20%, and $5.5 million and 20%, respectively, from a high of $9.2 million and
31%, respectively, during the year ended December 31, 1990.  Although software
research and development costs will continue, management expects these costs to
decrease as a percentage of revenue in the future.  In an effort to reduce the
internal capital requirements for these projects, the Company actively pursues
opportunities to fund software research and development costs through
development projects with oil and gas industry partners, government agencies
and others.  In this type of funded development project, participating
companies or other entities provide all or a portion of the funds required to
develop or enhance a software product in exchange for access to the resulting
software at discounted or nominal prices with the Company retaining ownership
and licensing rights to the product.  In accordance with generally accepted
accounting principles, the Company generally records as consulting revenue
amounts received from these third parties and capitalizes the qualifying
portion of related costs incurred as software development costs in accordance
with FASB Statement 86.

         The Company believes that (a) amounts expected to continue to be
available under the Company's revolving credit facility and (b) internally
generated funds, should provide the Company with sufficient liquidity and
working capital to meet its anticipated operating needs.  There can be no
assurance, however, that the Company will generate sufficient cash flow from
operations to meet its future operating needs or be successful in obtaining any
additional debt or equity financing.

PUBLIC OFFERING AND OTHER EQUITY TRANSACTIONS.  On June 30, 1994, the Company
sold 2.0 million newly issued shares of common stock in a public offering from
which the Company received net proceeds of $8.1 million, net of related costs
of approximately $270,000.  The Company used the proceeds from the public
offering to repay its bank indebtedness of $5.1 million, to reduce accounts
payable, and to increase working capital.

         In July 1994 the underwriters of the public offering exercised an
overallotment option, resulting in the sale by the Company of 383,000
additional newly issued shares of common stock, from which the Company received
net proceeds of approximately $1.6 million.

         Simultaneously with completion of the public offering, Renaissance
Capital Partners II, Ltd. ("Renaissance") converted $1.75 million in principal
amount of convertible debentures (see Notes 2 and 3 to Consolidated Financial
Statements) into 653,846 shares of common stock, which Renaissance sold in the
public offering.  As a result of the Renaissance conversion, the Company
reduced paid-in capital by $119,000 for unamortized debt issuance costs related
to the converted debentures.

         Also, in 1994, the Company received net proceeds of approximately $1.0
million from the sale of newly issued common stock in connection with exercises
of stock options.

BANK REVOLVING CREDIT FACILITY.  Effective September 21, 1994, the Company
established a new primary banking relationship, which includes a loan agreement
with the bank that provides for a revolving credit facility pursuant to which
the Company may utilize up to $6.0 million for: (a) short-term borrowings for
working capital purposes and (b) the issuance of letters of credit for bid
guarantees, performance bonds, and advance payment guarantees.

         Borrowings and outstanding letters of credit are collateralized by
substantially all the Company's assets, excluding those of the Company's
Canadian subsidiary.  The maximum amount of cash borrowings and letters of
credit that may be outstanding at any time is determined by a borrowing base
formula related to available collateral.  The credit facility consists of a
foreign portion under which up to $5.0 million cash borrowings and letters of
credit may be outstanding if sufficient collateral of foreign accounts
receivable is available and a domestic portion under which up to $1.5 million
of





                                      -19-
<PAGE>   20
cash borrowings and letters of credit may be outstanding if sufficient
collateral of domestic accounts receivable is available.  At December 31, 1994,
the Company elected to limit insurance coverage of domestic accounts receivable
because the Company did not require financing to the full extent of the
revolving credit facility.  This enabled the Company to reduce insurance
premium costs and decreased the amount of  available credit to $1.4 million.
On a fully-guaranteed, fully-insured basis, the Company estimates that
qualifying collateral would have resulted in total available credit of
approximately $4.8 million at December 31, 1994.

         The foreign portion of the credit facility is supported by a $4.5
million guarantee by the Export-Import Bank of the United States.  The
revolving credit facility is available through July 15, 1995, concurrent with
the term of the current  Export-Import Bank guarantee.  The Company believes
that, as in the past, the Export-Import Bank will continue to grant additional
terms of its guarantee.  The Company intends to request an increase to the
amount guaranteed to $5 million if necessary for working capital needs.  The
Company expects that the Export-Import Bank would agree to such an increase, if
requested.

         As of December 31, 1994, the borrowing base, amounts of short-term
cash borrowings and letters of credit outstanding, and credit available under
the revolving credit facility were as follows:

</TABLE>


         Interest rates applicable to short-term cash borrowings under the
foreign portion of the credit facility are equal to the bank's prime rate of
interest.  Interest rates applicable to short-term cash borrowings under the
domestic portion of the credit facility are equal to the bank's prime rate of
interest plus 1.5%.  The weighted average interest rates incurred by the
Company were 8.7% and 8.5% in the years ended December 31, 1994 and 1993,
respectively.  At December 31, 1994, the interest rates applicable to
short-term cash borrowings were 8.5% and 10.2% for the foreign and domestic
portions of the line of credit, respectively.  The Company pays 2% annually for
outstanding letters of credit.  The agreement requires that the Company meet
certain requirements regarding operating results and financial condition, and
prohibits the Company from paying dividends without the bank's prior written
consent.  As of December 31, 1994, the Company is not in compliance with
certain financial covenants.  The bank has agreed to a forbearance of these
covenant violations.

         The Company pays to the Export-Import Bank an annual fee of $67,500,
equal to 1.5% of the amount of the guarantee.  In addition, the Company is
required to purchase credit insurance for all foreign and certain domestic
receivables at a cost of 0.25% of the amount of the insured receivables.

         In January 1995, the Company's United Kingdom subsidiary obtained a
bank line of credit of $300,000 for working capital financing of its projects.
This line of credit is collateralized by a Letter of Credit for $300,000, which
was issued by the Company's primary bank pursuant to the revolving credit
facility described above.  Interest related to borrowings on the United Kingdom
line of credit is charged at a rate per annum equal to the bank's prime rate of
interest plus 1.75%.

         The Company's Canadian subsidiary has a bank line of credit of
approximately $650,000 for working capital financing of its projects.  At
December 31, 1994, the Canadian subsidiary had no outstanding borrowings under
this arrangement.  Interest related to borrowings on the Canadian line of
credit is charged at a rate per annum equal to the bank's prime rate of
interest plus 1.25%.

RESULTS OF OPERATIONS

OVERALL OPERATING RESULTS

         1994 Compared to 1993.  The Company reported a loss before income
taxes of $4,630,000 in 1994.  The Company reported income before income taxes
of $2,087,000 in 1993.  In the fourth quarter of 1994 the Company increased its
provision for doubtful accounts by $5,854,000 because of uncertainty about
collectibility of accounts receivable from certain VARs, previously in the
Company's Pipeline and Facilities Division and London office.  The 1994 loss
also resulted partly from lower development and production consulting revenue
due to the timing of work on large foreign consulting contracts.  Additionally,
the Company increased its sales and marketing expenses, including increased
costs for further market penetration of the WorkBench and the Company's other
products.  Increased investment in sales and marketing activities to contribute
to future growth of the Company was one of the intended uses of part of the
proceeds of the June 1994 public offering of common stock.  The Company plans
to continue an increased level of sales and marketing expenses for several
additional quarters, which has the effect of decreasing reported income from
operations until such time that the Company realizes sufficient additional
revenue and profits as a result of the increased sales and marketing
activities.

         Part of the Company's marketing strategy has been to establish
strategic alliances with quality VARs. VARs license the Company's software
products for remarketing and sublicensing to end users or to other VARs, either
for use on a specific project for a specific customer or for general marketing
to the VARs' current and future customers.  The Company's VARs are generally
substantial companies with long operating histories.  The software products
licensed to VARs are established, proven products that have long been widely
accepted in the marketplaces served by the Company.

         In some cases, primarily to obtain preferential pricing, a VAR  makes
an unconditional commitment to pay to the Company a fixed license fee for
software to be used on a specific project for a specific customer or an
unconditional commitment to pay to the Company a minimum fixed fee for the
right of general marketing to the VAR's current and future customers for a
specified period, usually one-year.  In the case of general marketing rights, a
VAR is required to pay license fees as it has transactions with its customers.
On the due date or dates of a minimum fixed fee, which are payable either in
installments or at the end of the term of a VAR agreement, the VAR must pay to
the Company the amount, if any,  required for total payments to equal the
required minimum fixed fee amount.  General marketing VAR minimum fixed fees
are not subject to reduction based on the number of units marketed by a VAR and
are not otherwise contingent on whether a VAR is successful in marketing the
Company's software products or otherwise.

         In accounting for a VAR agreement, the Company recognizes revenue at
inception of the contract only if collection is determined to be probable and
all other requirements for revenue recognition are met.  These include: (a)
delivery of all software products on all platforms that a VAR has the right to
receive, (b)  reviewing the VAR's credit status to determine whether the VAR
has the financial capability to make the required fixed minimum payments,
regardless of whether the VAR is successful in marketing the Company's software
products, (c) determining that the VAR is not new, undercapitalized, or in
financial difficulty, and (d)  determining that the transaction is viable for
both parties.





                                      -21-
<PAGE>   22
         In the fourth quarter of 1994, certain VARs of the Company's Pipeline
and Facilities Division did not pay fixed fees when due for certain software
licensed for use on specific projects for specific customers and also certain
minimum fixed fees for rights of general marketing.

         In the fourth quarter of 1994 the Company increased its 1994 provision
for doubtful accounts by $5,854,000, of which $1,958,000 was related to the
fixed fee payments due from VARs.  The Company has determined that the chance
is remote that it will be able to collect accounts receivable of $2,118,000, of
which $1,437,000 is related to fixed fee amounts from VARs.  Accordingly, in
the December 31, 1994 balance sheet, the Company has written off accounts
receivable totaling $2,118,000.  The Company had previously filed a Form 10-K
with unaudited financial statements for the year ended December 31, 1994 which
showed a fourth quarter provision for doubtful accounts in the amount of
$2,443,000.  The increase of $3,411,000 is attributable to several accounts
which the Company has since been unable to collect and the Company, upon the
basis of facts and circumstances subsequent to the previously filed Form 10-K,
has determined that collection of these amounts is not now imminent.

         The Company commenced and continues to have discussions with VARs that
owe the Company the remaining fixed fees and is in the process of determining
if resolutions acceptable to each VAR and the Company are possible.  The need
of the Company to undertake an inquiry and the need of its auditors to await
the completion of the inquiry and to undertake their own due diligence resulted
in a substantial delay in completing the audit of the Company's 1994 financial
results.

         Effective with the fourth quarter of 1994 the Company is using
significantly more stringent qualitative and quantitative criteria and
guidelines in deciding if a VAR's fee should be considered  a fixed fee that
enables revenue recognition at inception of the VAR arrangement if all other
revenue recognition requirements are met.

         In connection with the non-payment by VARs of minimum fixed fees,
which had been recognized by the Company as revenue, the Company conducted an
investigation and discovered that certain persons in its Pipeline and
Facilities Division had indicated in writing to some of the VARs in connection
with thirteen contracts involving aggregate payments of $2,331,000 that payment
of the fixed fees would not be required under specified conditions, generally
related to whether the VARs were successful in sublicensing the software to
specific customers for use on specific projects or to other customers of the
VARs.  Most of such written representations were signed by Division employees
who are no longer employed by and have no present association with the Company.

         Upon learning of the foregoing written representations, and after
consultation with the Company's auditors, Hein + Associates, the Audit
Committee of the Board of Directors of the Company on April 27, 1995 appointed
a Special Committee, consisting of an outside Director, the Company's outside
principal legal counsel and its Chief Financial Officer, to investigate the
circumstances related to these representations and the related VAR agreements.
During the following two months the Committee interviewed thirty current and
former Company employees and extensively reviewed Company files.  Hein +
Associates was kept informed throughout of the results of the investigation and
from time to time made suggestions to the Special Committee for particular
inquiries, which suggestions were followed.

         In a May 30, 1995 report to the Audit Committee and the Board of
Directors the Special Committee concluded that the representations to the VARs
were not authorized by the Company and were not approved in advance by any of
the Company's executive officers, except for one situation described below, nor
was their existence known by any of the Company's accounting personnel.  The
Committee concluded that the individuals who made the representations about
deferral of the obligations of VARs to pay license fees until resales occurred
believed that such resales were certain to occur on a timely basis (which in a
number of instances proved correct) and therefore believed that the
representations were not material.  The Company, with the consultation and
approval of the Board of Directors, has established rigorous controls and
procedures to guard against similar unauthorized





                                      -22-
<PAGE>   23
representations to the Company's clients in the future and the Board of
Directors has also determined sanctions for those few individuals that the
Company continues to employ who had involvement with the unauthorized
representations.  These controls and procedures, as well as the sanctions, were
discussed with Hein + Associates prior to their implementation, who agreed to
their propriety.

         Subsequent to the May 30, 1995 report, it was discovered that an
Executive Vice President and Director of the Company had been involved in a
similar representation to another VAR.  The Special Committee supplemented its
inquiry to include that situation and concluded in a supplemental report to the
Board of Directors describing this situation that the Committee's previous
conclusions with respect to the non-involvement of any of the Company's other
executive officers and of its accounting personnel remained correct.  The
Special Committee also concluded that there were no facts or circumstances that
suggested that there were any additional remaining similar representations to
VARs or others which had not been investigated.  As a result of this situation,
on June 21, 1995, upon recommendation of the Chief Executive Officer of the
Company, the Board of Directors approved the immediate termination of such
Executive Vice President as an officer and employee of the Company.

         The individuals who made the representations were not actually
authorized to do so by the Company.  Also, legal counsel to the Company has
advised that there was no apparent authority basis for their representations.
Almost all of the related VAR agreements do not allow modifications to the
payment obligations of the VARs in the manner purported by the unauthorized
representations.  The Company's legal counsel has advised it that the
representations are not enforceable, that they may be disavowed by the Company,
and that the fixed fees required by the VAR agreements are due and payable.

         The Company remained in essentially daily communication with Hein +
Associates throughout this two month inquiry period.  During June, the Company
also advised its former auditors, Ernst & Young, with respect to its 1992
audited financial statements of the situation with the representations to the
VARs and the special inquiry.  Ernst & Young indicated to the Company that it
would need to perform its own extensive due diligence with respect to this
situation and the 1992 financial statements before it could consent to the use
of its audit opinion on those financial statements in spite of the fact that
Hein + Associates was able to advise Ernst & Young that nothing had come to
their attention with respect to the 1992 financial statements which would have
a material effect upon them.  Ernst & Young could further not inform the
Company of how much time or how much expense might be involved in the work
which it would need to do in connection with the 1992 financial statements.
The Company considered a number of alternatives in connection with the 1992
financial statements including the possibility of having those financial
statements reaudited by Hein + Associates but no conclusion was reached in this
respect. .  The unaudited financial statements for 1992 included herein are the
same as the audited statements previously filed in the Form 10-K for that year.

         Throughout the month of June, 1995 the Company assumed, upon the basis
of its frequent communications with Hein + Associates, that the audit of its
1994 financial statements would be promptly completed and the numerous repeated
delays in such completion therefore were not anticipated by the Company.  On
June 30, 1995, the Company was advised by Hein + Associates that it was
resigning as the Company's auditor for its 1994 financial statements although
it was not withdrawing its audit opinion with respect to the Company's 1993
financial statements.  Hein + Associates had not previously discussed the
possibility of resignation during the two month special inquiry period.  Hein +
Associates did not provide the Company with any specific reason or reasons for
its resignation other than to indicate that it was due to a number of factors.
Hein + Associates has however agreed with the Company that such resignation was
not due to any disagreement with the Company over accounting principles or
practices, financial statement disclosure, or auditing scope or procedure.

         Hein + Associates did not furnish any reason to the Company at the
time of its June 30 resignation or in the July 3 meeting, or with the July 6
communication, for its resignation and declined repeated requests from the
Company and others during the following two weeks for an explanation.  On





                                      -23-
<PAGE>   24
July 19, 1995 Hein + Associates furnished the Company with a letter advising it
that it had resigned because of a "risk of management misrepresentations" in
the financial statements.  This was the first time any such allegation had been
made throughout the entire investigating period.

         The July 19, 1995 letter of Hein + Associates also indicated that the
timing of adjustments related to the side letters was not resolved at the time
of its resignation.  The Company was however led to believe through its daily
contacts with Hein + Associates that they had in fact reached agreement on the
accounting for the transactions involving the side letters, including the fact
that in mid-June Hein + Associates had approved a final draft of the financial
statements for filing with the SEC, which was then not filed only when the
additional side letter problem involving the Company's former Executive Vice
President was discovered and required analysis.

         On September 22, 1995, the Board of Directors of the Company approved
the selection of Ehrhardt Keefe Steiner & Hottman PC as its auditors.

REVENUE

         1994 COMPARED TO 1993.  Total revenue decreased 8% to $27.9 million in
1994 from $30.3 million in 1993.  The Company reported lower revenue from both
consulting and training and also licenses and maintenance, primarily because of
the reasons discussed in the "Overall Operating Results" section.

         Total revenue from development and production products and services
decreased 3% to $17.4 million in 1994 from $18.0 million in 1993.  However,
software license and maintenance revenue increased 11% to $6.2 million in 1994
from $5.7 million in 1993.  Total revenue from the Petroleum WorkBench
increased 54% to $3.7 million in 1994 from $2.4 million in 1993.  Consulting
and training revenue decreased 13% to $10.5 million in 1994 from $12.0 million
in 1993 because of the reason discussed in the "Overall Operating Results"
section.

         Total revenue from pipeline and surface facilities products and
services decreased 13% to $7.1 million in 1994 from $8.2 million in 1993.
Consulting and training revenue decreased 36% to $2.7 million in 1994 from $4.2
million in 1993.  In 1993, the pipeline and surface facilities division had
higher consulting revenue due to continued work on the final stages of several
of the significant combined software and services contracts that were initiated
in 1991.  Software license and maintenance revenue increased 16% to $4.3
million in 1994 from $3.7 million in 1993.

         Total revenue from graphical user interface ("GUI") products and
services decreased 21% to $3.3 million in 1994 from $4.2 million in 1993.
Software license and maintenance revenue decreased 26% to $2.0 million in 1994
from $2.7 million in 1993.  The decrease was attributable primarily to what the
Company believes is a temporary decline in the aerospace industry market and
because of a temporary reduction in sales personnel during a period of internal
reorganization of the Kinesix division's sales force.

         1993 COMPARED TO 1992.  Total revenue increased 4% to $30.3 million in
1993 from $29.2 million in 1992 primarily as a result of increased sales of
Sammi and Petroleum WorkBench and related consulting services.  Total revenue
from the Company's Sammi and Petroleum WorkBench products and services
increased 25% to $6.6 million in 1993 from $5.3 million in 1992.  Revenue from
the Company's stand-alone products and services declined slightly to $23.7
million in 1993 as compared to $23.9 million in 1992.

         Total consulting and training revenue increased 7% to $17.7 million in
1993 from $16.5 million in 1992, primarily as a result of higher consulting
revenue from new foreign contracts in the exploration and production division,
which was partially offset by a decline in revenue from the Company's pipeline
and surface facilities division.  The Company's total license and maintenance
revenue declined by $299,000 during 1993 when compared to 1992, which was
partially offset by a $216,000 increase in other revenue.





                                      -24-
<PAGE>   25
         Total revenue from development and production products and services
increased 8% to $18.0 million in 1993 from $16.7 million in 1992.  Consulting
and training revenue in this area increased 13% to $12.0 million in 1993 from
$10.6 million in 1992 as a result of new foreign contracts.  Development and
production software license and maintenance revenue decreased slightly to $5.7
million in 1993 as compared with $5.8 million in 1992 primarily due to
decreased sales of the Company's stand-alone products.

         Total revenue from pipeline and surface facilities products and
services decreased 7% to $8.2 million in 1993 from $8.8 million in 1992 as a
result of a decrease in consulting and training revenue of 17% to $4.2 million
in 1993 from $5.1 million in 1992.  In 1992, the pipeline and surface
facilities division had higher consulting revenue due to the significant
combined software and services contracts that were initiated in 1991.

         Total revenue from GUI products and services increased 10% to $4.2
million in 1993 as compared to $3.8 million in 1992 as a result of an increase
in consulting and training revenue to $1.4 million in 1993 from $800,000 in
1992.  The base of clients for GUI consulting and training services has
increased as a result of the sales of GUI software licenses during 1993 and
1992.  Software license and maintenance revenue for GUI products decreased 10%
to $2.7 million in 1993 as compared with $3.0 million in 1992.

FOREIGN REVENUE

         Revenue derived from foreign sources during 1994, 1993 and 1992 is set
forth below:

<TABLE>

                 Revenue From          Percentage of

   <S>             <C>                     <C>
   1994            $18,214                  65%
   1993             18,541                  61%
   1992             17,145                  59%
</TABLE>


         Management believes that foreign revenue will continue to be an
important factor in the Company's business, primarily as a result of continued
penetration of international markets through the Company's strategic marketing
efforts.  See "Business -- Geographic and Business Line Data" for information
regarding the particular geographic areas in which the Company generated
foreign source revenue during these periods.

COSTS OF CONSULTING AND COSTS OF LICENSES AND MAINTENANCE

         1994 COMPARED TO 1993.  Costs of consulting and training decreased to
$11.3 million in 1994 from $12.5 million in 1993.  The decrease resulted
primarily from the lower level of consulting activity in 1994 because of the
reason discussed in the "Overall Operating Results" section.  Costs of
consulting and training were 75% of consulting and training revenue in 1994 and
70% in 1993.

         Costs of licenses and maintenance decreased to $6.0 million in 1994
from $6.6 million in 1993,  including software amortization of $4.6 million in
1994 and $4.1 million in 1993.  Costs of licenses and maintenance were 48% of
license and maintenance revenue in 1994 and 54% in 1993.

         1993 COMPARED TO 1992.  Direct costs of consulting and training
increased to $12.5 million in 1993 from $12.0 million in 1992.  Direct costs of
consulting and training were 70% of consulting training revenue in 1993 as
compared to 73% in 1992.  The decrease in consulting and training costs as a
percentage of revenue was attributable to minor variations in gross margins
realized on consulting contracts.





                                      -25-
<PAGE>   26
         Costs of licenses and maintenance were $6.6 million in 1993 as
compared to $6.2 million in 1992, including amortization of software of $4.1
million in 1993 and $3.6 million in 1992.  Total costs of license and
maintenance revenue were 54% of license and maintenance revenue in 1993 as
compared to 50% in 1992 with the increase being attributable primarily to
increased software amortization expense.

CONTRACT COST ACCRUALS (REVERSALS)

         Contract cost accruals and reversals are recognized on certain
combined software and service contracts as required based on the percentage of
completion applied to total estimated project costs in order to recognize a
constant gross margin over the term of such contracts.  Contract cost
(reversals) of ($4,000) in 1994, ($333,000) in 1993, and ($392,000) in 1992,
respectively, are included in costs and expenses in the statement of operations
and relate to the reversal of previous accruals to provide constant gross
margins over the terms of the contracts.  Contract cost accruals result in the
recognition of a portion of contract costs as expenses before they are
incurred.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

         1994 COMPARED TO 1993.  Selling, general, and administrative expenses
increased to $13.7 million in 1994 from $7.3 million in 1993.  The increase was
primarily attributable to the increase to the allowance for doubtful accounts
of $5,854,000, which is discussed under "Overall Operating Results."  Also, the
Company increased its sales and marketing activities, including  increased
costs for the purpose of further market penetration of the WorkBench and the
Company's other products.

         1993 COMPARED TO 1992.  Selling, general and administrative costs
decreased to $7.3 million in 1993 as compared to $8.2 million in 1992.  The
decrease was primarily attributable to reorganization of the exploration and
production division's sales and marketing staff.

SOFTWARE RESEARCH AND DEVELOPMENT

         Following is a summary of costs of development and enhancement of the
Company's software products for 1994, 1993, and 1992,  the amounts capitalized
in accordance with FASB Statement No. 86, the amounts charged to research and
development expense, the amounts of capitalized costs amortized, and the total
amounts recognized as expense in the statements of operations.

</TABLE>

         The capitalized software costs of $5.6 million for 1994, include a
one-time payment by the Company of $100,000 to acquire a paid-up software
license for software owned by a third party that is included as a component of
several of the Company's software products.  The Company had previously paid
royalties to the third party equal to a percentage of the Company's revenue
from those products.  As a result of this payment, the Company will not be
required to pay such royalties in the future.

         The Company has continued its commitment to the development and
enhancement of its software products.  Capitalized software costs increased in
1994 partly as a result of acceleration of development activities for the
WorkBench.  These activities were accelerated to enable providing an enhanced
product to the marketplace, which the Company believes will complement the
increased sales and marketing efforts.





                                      -26-
<PAGE>   27
         The Company capitalizes qualifying costs incurred in developing and
enhancing its software products in accordance with FASB Statement 86 upon
determining technological feasibility with respect to the product or
enhancement.  See Note 1 to the Consolidated Financial Statements.  Capitalized
costs of each software product are amortized over the applicable useful life of
that product.  The capitalized software development costs of the Company's
stand-alone software products are amortized over a 13-year useful life because
the fundamental equations that represent the foundations of these software
products are based upon unchanging scientific principles and thus management
believes these products have useful lives that are relatively longer than other
software products.  The unchanging characteristics of the underlying
fundamental equations that represent the foundation of the Company's software
products also means that technological feasibility of new products and
enhancements is generally determined relatively early in the development
process.  Thus, in accordance with Statement 86, the Company begins
capitalizing qualifying software development costs at a relatively earlier
stage than may be the case with other software companies.

         The Company amortizes the capitalized costs of Petroleum WorkBench and
Sammi over a seven-year period.  Although the amortization periods utilized by
the Company for its products are longer than the amortization periods generally
used in the software industry, management believes that these periods are
consistent with generally accepted accounting principles and are appropriate
based upon the relatively longer useful lives of the Company's software
products.

         Capitalized software is stated at the lower of cost or net realizable
value.  The Company capitalizes costs of purchased software and qualifying
internal costs of developing and enhancing its software products, in accordance
with FASB Statement  86.

         Amortization of capitalized software costs is determined each year
based on the greater of: (1) the amount computed using the ratio of current
year gross revenues to the sum of current and anticipated future gross revenue
for that product, or (2) straight-line amortization.  The Company uses the
following useful lives in computing straight-line amortization: basic
technology for exploration, production, and pipeline software products and
enhancements, 13 years; Petroleum WorkBench and Sammi, 7 years.

         Effective January 1, 1994, the Company allocated 67% of the net book
value of its basic technology computer aided production software products,
amounting to $9,850,000, to the carrying value of the Petroleum WorkBench.
Petroleum WorkBench is an integrated software system that includes the basic
technology production software products.  Petroleum WorkBench, which  operates
on workstations and personal computers, enables integrated use of the basic
technology software products more quickly and efficiently than with individual
and non-integrated  products.  The Company will also continue to market the
basic technology production software products on a stand-alone basis.

         The amounts allocated were substantially in proportion to respective
estimated future revenue projections for the Petroleum WorkBench and the basic
technology software products.  The amounts allocated to the Petroleum WorkBench
are being amortized over a 7-year period commencing January 1, 1994.  The
Company is continuing to amortize the remaining unamortized cost of the basic
technology software products over 13 years.

FOREIGN EXCHANGE GAINS (LOSSES)

         The Company's foreign exchange gains and losses relate principally to
the effects of fluctuations in the exchange rate of the British pound on
transactions of the Company's subsidiary in the United Kingdom that are
denominated in other currencies.

         In 1994 and 1993, the Company recognized net foreign exchange losses
of $84,000 and $141,000, respectively, primarily because of strengthening of
the British pound against the U.S. dollar.  In 1992 the Company recognized net
foreign exchange gains of $116,000 principally as a result of the weakening of
the British pound against the U.S.  dollar.

              SCIENTIFIC SOFTWARE-INTERCOMP, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS

         Scientific Software-Intercomp, Inc. ("the Company") develops and
markets sophisticated software for the development and production and pipeline
and surface facilities areas of the worldwide oil and gas industry and for
graphic user interface applications.  The Company provides consulting and
technical support services in each of these areas.

PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of
Scientific Software-Intercomp, Inc. ("the Company"), and its wholly-owned
subsidiaries, after elimination of all significant intercompany balances and
transactions.

LIQUIDITY

         The liquidity and financial condition of the Company improved
significantly during 1994 as a result of the sale of common stock in the June
1994 public offering and other capital transactions described below.  At
December 31, 1994, the Company's working capital ratio was 1.4 to 1, based on
current assets of $12.7 million and current liabilities of $9.2 million.  The
Company's working capital ratio at December 31, 1993, was 1.39 to 1.  Total
stockholders' equity increased to $28.4 million at December 31, 1994, from
$20.5 million at December 31, 1993.

         At December 31, 1993 and 1992, the Company had positive working
capital of $4.4 million and $1.9 million, respectively.  During 1992 and 1993,
the Company undertook a series of steps to increase its financial flexibility
and liquidity.  In September 1992, the Company issued a $2.5 million 7-year
convertible debenture to Renaissance Capital Partners II, Ltd. ("Renaissance")
and in September 1993 issued a $1.0 million 7-year convertible debenture to
Renaissance.  See Note 3 to the Consolidated Financial Statements.  In January
1994, the Company extended the maturity of its revolving credit facility, and
the related guarantee issued by the United States Export-Import Bank, through
January 1995. The $5.0 million outstanding under the Company's revolving credit
facility at December 31, 1993 was classified as a long-term liability.

         The Company believes that its improved financial condition and
liquidity will enable increased efforts aimed at further market penetration of
its new WorkBench and Sammi products, as well as increased efforts aimed at
further market penetration of its traditional products and services.

         The Company's working capital and cash requirements will continue to
be influenced by the level of software research and development costs.  During
the years ended December 31, 1994 and 1993, the Company reduced the level of
software research and development costs, in the aggregate and as a percentage
of total costs incurred (excluding software amortization), to $6.4 million and
20%, and $5.5 million and 20%, respectively, from a high of $9.2 million and
31%, respectively, during the year ended December 31, 1990.  Although software
research and development costs will continue, management expects these costs to
decrease as a percentage of revenue in the future.  In an effort to reduce the
internal capital requirements for these projects, the Company actively pursues
opportunities to fund software research and development costs through
development projects with oil and gas industry partners, government agencies
and others.  In this type of funded development project, participating
companies or other entities provide all or a portion of the funds required to
develop or enhance a software product in exchange for access to the resulting
software at discounted





                                      -37-

or nominal prices with the Company retaining ownership and licensing rights to
the product.  In accordance with generally accepted accounting principles, the
Company generally records as consulting revenue amounts received from these
third parties and capitalizes the qualifying portion of related costs incurred
as software development costs in accordance with FASB Statement 86.

         The Company believes that (a) amounts expected to continue to be
available under the Company's revolving credit facility and (b) internally
generated funds, should provide the Company with sufficient liquidity and
working capital to meet its anticipated operating needs.  There can be no
assurance, however, that the Company will generate sufficient cash flow from
operations to meet its future operating needs or be successful in obtaining any
additional debt or equity financing.

REVENUE

         The Company recognizes software license revenue on delivery  and
recognizes maintenance revenue on a straight-line basis over the term of the
contract.

         Beginning in 1991 the Company entered into certain combined software
and service contracts pursuant to which the Company provides off-the-shelf
software, combined with pipeline engineering services, relating to leak
detection and operations analysis of pipeline networks.  The engineering
services provided pursuant to these contracts include analysis of the
characteristics of the client's specific pipeline network and entering these
characteristics into the Company's software.  Programming changes to the
off-the-shelf software are not necessary for completion of the contract.  The
Company also markets the off-the-shelf software for use by clients, as is,
without the services included in these contracts.  The Company measures
progress-to-completion for combined software and services contracts on a value
added output basis for the off-the-shelf software portion of the contracts
when:  (1) a license for the off-the-shelf software has been executed that is
enforceable for the customary price of the Company's off-the-shelf software,
(2) the off-the-shelf software has been installed on the project computer, and
(3) the installed off-the-shelf software has been used for completing and
providing to the client specifications for the engineering services on the
project, which have been accepted by the client.  The Company measures
progress-to-completion for the engineering services portion of the contracts
based on labor hours incurred.  Contract costs are recognized based on the
percentage of completion applied to total estimated project costs, resulting in
a constant gross margin percentage over the term of the contract.  Net contract
cost (reversals) of ($4,000), ($333,000), and ($392,000), are included in costs
and expenses in the statements of operations for 1994, 1993 and 1992,
respectively, related to the accrual and reversal of costs to provide the
constant gross margin over the term of each contract.

         Revenue earned in performance of time and material contracts is
recognized at contractual rates as labor hours and associated costs are
incurred.  Fixed-price contract revenue is recognized using the percentage of
completion method, calculated based on the ratio of labor hours incurred to
total projected labor hours.  Revenue accrued under time and material contracts
is classified as work in progress if contractual milestones for billing have
not been reached.  Such amounts are later billed in accordance with applicable
contract terms.  The work in progress amounts at December 31, 1994, are
expected to be billed and collected by December 31, 1995.  Losses on contracts
accounted for using the percentage of completion method are recognized at the
time they are identified.  Costs incurred for specific anticipated contracts
are deferred when recoverability of the costs from the anticipated contract is
determined to be probable.

         Work in progress at December 31, 1994 and 1993, includes $301,000 and
$314,000, respectively, related to fixed price contracts for the development of
software that is funded by others.  The revenue on these contracts is
recognized using the percentage of completion method, and related qualifying
software development costs are capitalized if the Company retains ownership and
the right to market the developed software.

         Part of the Company's marketing strategy has been to establish
strategic alliances with quality VARs. VARs license the Company's software
products for remarketing and sublicensing to end users or to other VARs, either
for use on a specific project for a specific customer or for general marketing
to the VARs' current and future customers.  The Company's VARs are generally
substantial companies with long operating histories.  The software products
licensed to VARs are established, proven products that have long been widely
accepted in the marketplaces served by the Company.

         In some cases, primarily to obtain preferential pricing, a VAR  makes
an unconditional commitment to pay to the Company a fixed license fee for
software to be used on a specific project for a specific customer or an
unconditional commitment to pay to the Company a minimum fixed fee for the
right of general marketing to the VAR's current and future customers for a
specified period, usually one-year.  In the case of general marketing rights, a
VAR is required to pay license fees as it has transactions with its customers.
On the due date or dates of a minimum fixed fee, which are payable either in
installments or at the end of the term, the VAR must pay to the Company the
amount, if any,  required for total payments to equal the required minimum
fixed fee amount.  General marketing VAR minimum fixed fees are not subject to
reduction based on the number of units marketed by a VAR and are not otherwise
contingent on whether the a VAR is successful in marketing the Company's
software products or otherwise.

         In accounting for a VAR agreement, the Company recognizes revenue at
inception of the contract only if collection is determined to be probable and
all other requirements for revenue recognition are met.  These include: (a)
delivery of all software products on all platforms that a VAR has the right to
receive, (b)  reviewing the VAR's credit status to determine whether the VAR
has the financial capability to make the required fixed minimum payments,
regardless of whether the VAR is successful in marketing the Company's software
products, (c) determining that the VAR is not new, undercapitalized, or in
financial difficulty, and (d)  determining that the transaction is viable for
both parties.

         In the fourth quarter of 1994 the Company increased its 1994 provision
for doubtful accounts by $5,854,000, of which $1,958,000 was related to the
fixed fee payments due from VARs.  The Company has determined that the chance
is remote that it will be able to collect accounts receivable of $2,118,000, of
which $1,437,000 is related to fixed fee amounts from VARs.  Accordingly, in
the December 31, 1994 balance sheet, the Company has written off accounts
receivable totaling $2,118,000.  The Company had previously filed a Form 10-K
with unaudited financial statements for the year ended December 31, 1994 which
showed a fourth quarter provision for doubtful accounts in the amount of
$2,443,000. The increase of $3,411,000 is attributable to several accounts
which the Company has since been unable to collect and the Company, upon the
basis of facts and circumstances subsequent to the previously filed Form 10-K,
has determined that collection of these amounts is not now imminent.

         The Company commenced and continues to have discussions with VARs that
owe the Company the remaining fixed fees and is in the process of determining
if resolutions acceptable to each VAR and the Company are possible.  The need
of the Company to undertake the foregoing inquiry and the need of its auditors
to await the completion of the inquiry and to undertake their own due diligence
resulted in a substantial delay in completing the audit of the Company's 1994
financial results.

         Effective with the fourth quarter of 1994 the Company is using
significantly more stringent qualitative and quantitative criteria and
guidelines in deciding if a VAR's fee should be considered  a fixed fee that
enables revenue recognition at inception of the VAR arrangement if all other
revenue recognition requirements are met.

CAPITALIZED SOFTWARE COSTS

         Capitalized software is stated at the lower of cost or net realizable
value.  The Company capitalizes costs of purchased software and qualifying
internal costs of developing and enhancing its software products, in accordance
with FASB Statement 86.

         Amortization of capitalized software costs is determined each year
based on the greater of: (1) the amount computed using the ratio of current
year gross revenues to the sum of current and anticipated future gross revenue
for that product, or (2) straight-line amortization.  The Company uses the
following useful lives in computing straight-line amortization: basic
technology for exploration, production, and pipeline software products and
enhancements, 13 years; Petroleum WorkBench and Sammi, 7 years.

         Effective January 1, 1994, the Company allocated 67% of the net book
value of its basic technology computer aided production software products,
amounting to $9,850,000, to the carrying value of the Petroleum WorkBench.
Petroleum WorkBench is an integrated software system that includes the basic
technology production software products.  Petroleum WorkBench, which  operates
on workstations and personal computers, enables integrated use of the basic
technology software products more quickly and efficiently than with individual
and non-integrated  products.  The Company will also continue to market the
basic technology production software products on a stand-alone basis.

         The amounts allocated were substantially in proportion to respective
estimated future revenue projections for the Petroleum WorkBench and the basic
technology software products.  The amounts allocated to the Petroleum WorkBench
are being amortized over a 7-year period commencing January 1, 1994.  The
Company is continuing to amortize the remaining unamortized cost of the basic
technology software products over 13 years.

Following is a summary of capitalization and amortization for the Company's
software products.

PROPERTY AND EQUIPMENT

         Property and equipment are stated at cost, and depreciation and
amortization are provided on a straight-line basis over the estimated useful
lives of these assets.  Maintenance and repairs are charged to expense as
incurred.  The cost and accumulated depreciation and amortization of property
and equipment sold or otherwise disposed of are retired from the accounts and
the resulting gain or loss is included in profit or loss in the period
realized.  Total depreciation expense was $740,000, $614,000, and $671,000 for
the years ended December 31, 1994, 1993, and 1992, respectively.

FOREIGN CURRENCY TRANSLATION

         Gains and losses from the effects of exchange rate fluctuations on
transactions denominated in foreign currencies are included in results of
operations.  Assets and liabilities of the Company's foreign subsidiaries are
translated into U.S. dollars at period-end exchange rates, and their revenue
and expenses are translated at average exchange rates for the period.  Deferred
taxes have not been allocated to the cumulative foreign currency translation
adjustment included in stockholders' equity because there is no intent to
repatriate earnings of the foreign subsidiaries.

INCOME TAXES

         The Company accounts for income taxes in accordance with FASB
Statement No. 109, Accounting for Income Taxes.  Under the provisions of
Statement 109, a deferred tax liability or asset is provided in the financial
statements by applying the provisions of applicable tax laws to measure the
deferred tax consequences of temporary differences that will result in net
taxable or deductible amounts in future years as a result of events recognized
in the financial statements in the current or preceding years.  The types of
differences between the tax bases of assets and liabilities and their financial
reporting amounts that give rise to significant portions of the temporary
differences include: software development expenditures capitalized for books
and deducted currently for taxes and related amortization, depreciation of
property and equipment, amortization of rental obligations, losses accrued for
book purposes, the recognition of software license revenues, and goodwill
determined for tax purposes that is not deductible.  Investment tax credits are
recognized using the flow-through method.

         Foreign subsidiaries are taxed according to applicable laws of the
countries in which they do business.  The Company has not provided U.S. income
taxes that would be payable on remittance of the cumulative undistributed
earnings of foreign subsidiaries because such earnings are intended to be
reinvested for an indefinite period of time.  At December 31, 1994, the
undistributed earnings of the foreign subsidiaries were not significant.

<PAGE>   42
INCOME PER SHARE

         Primary income per common and common equivalent share is computed
based on the weighted average number of common and dilutive common equivalent
shares consisting of stock options and redeemable preferred stock outstanding
during each period.  For the year ended December 31, 1994, no common stock
equivalents and stock options are included in the income per share calculation.
Fully diluted income per share assumes the effects of conversion of all
potentially dilutive securities, including the convertible debentures (see Note
3).  Fully diluted earnings per share is not presented for 1992 because the
effects of assumed conversion would be antidilutive.  Fully diluted earnings
per share is not presented for 1994 because of the net loss.

CASH EQUIVALENTS

         For purposes of the consolidated financial statements, the Company
considers all highly liquid debt instruments purchased with an original
maturity of three months or less to be cash equivalents.

NOTE 2 - COMPLETION OF PUBLIC OFFERING OF COMMON STOCK

         On June 30, 1994, the Company sold 2.0 million newly issued shares of
common stock in a public offering from which the Company received net proceeds
of $8.1 million, net of related costs of approximately $270,000.  The Company
used the proceeds from the public offering to repay its bank indebtedness of
$5.1 million, to reduce accounts payable, and to increase working capital.

         In July 1994 the underwriters of the public offering exercised an
overallotment option, resulting in the sale by the Company of 383,000
additional newly issued shares of common stock, from which the Company received
net proceeds of approximately $1.6 million.

         Simultaneously with completion of the public offering, Renaissance
Capital Partners II, Ltd. ("Renaissance") converted $1.75 million in principal
amount of convertible debentures (see Note 3) into shares of common stock,
which Renaissance sold in the public offering.  As a result of the Renaissance
conversion, the Company reduced paid-in capital by $119,000 for unamortized
debt issuance costs related to the converted debentures.

NOTE 3 - BANKING ARRANGEMENTS, LONG-TERM OBLIGATIONS AND NOTE PAYABLE

BANKING ARRANGEMENTS

         Effective September 21, 1994, the Company established a new primary
banking relationship, which includes a loan agreement with the bank that
provides for a revolving credit facility pursuant to which the Company may
utilize up to $6.0 million for: (a) short-term borrowings for working capital
purposes and (b) the issuance of letters of credit for bid guarantees,
performance bonds, and advance payment guarantees.

         Borrowings and outstanding letters of credit are collateralized by
substantially all the Company's assets, excluding those of the Company's
Canadian subsidiary.  The maximum amount of cash borrowings and letters of
credit that may be outstanding at any time is determined by a borrowing base
formula related to available collateral.  The credit facility consists of a
foreign portion under which up to $4.5 million cash borrowings and letters of
credit may be outstanding if sufficient collateral of foreign accounts
receivable is available and a domestic portion under which up to $1.5 million
of cash borrowings and letters of credit may be outstanding if sufficient
collateral of domestic accounts receivable is available.  At December 31, 1994,
the Company elected to limit insurance coverage of domestic accounts receivable
because the Company did not require financing to the full extent of the





                                      -42-
<PAGE>   43
revolving credit facility.  This enabled the Company to reduce insurance
premium costs and decreased the amount of available credit to $1.4 million.  On
a fully-guaranteed, fully-insured basis, the Company estimates that qualifying
collateral would have resulted in total available credit of  approximately $4.8
million at December 31, 1994.

         The foreign portion of the credit facility is supported by a $4.5
million guarantee by the Export-Import Bank of the United States.  The
revolving credit facility is available through July 15, 1995, concurrent with
the term of the current Export-Import Bank guarantee.  The Company believes
that, as it has for a number of years, the Export-Import Bank will continue to
grant additional terms of its guarantee.  The Company intends to request an
increase to the amount guaranteed to $5 million if necessary for working
capital needs.  The Company expects that the Export-Import Bank would agree to
such an increase, if requested.

         As of December 31, 1994, the borrowing base, amounts of short-term
cash borrowings and letters of credit outstanding, and credit available under
the revolving credit facility were as follows:

</TABLE>


         Interest rates applicable to short-term cash borrowings under the
foreign portion of the credit facility are equal to the bank's prime rate of
interest.  Interest rates applicable to short-term cash borrowings under the
domestic portion of the credit facility are equal to the bank's prime rate of
interest plus 1.5%.  The weighted average interest rates incurred by the
Company were 7.5% and 8.5% in the years ended December 31, 1994 and 1993,
respectively. At December 31, 1994, the interest rates applicable to short-term
cash borrowings were 8.5% and 10.2% for the foreign and domestic portions of
the line of credit, respectively.  The Company pays 2% annually for outstanding
letters of credit.  The agreement requires that the Company meet certain
requirements regarding operating results and financial condition, and prohibits
the Company from paying dividends without the bank's prior written consent.  As
of December 31, 1994, the Company is not in compliance with certain financial
covenants.  The bank has agreed to a forbearance of these covenant violations.

         The Company pays to the Export-Import Bank an annual fee of $67,500,
equal to 1.5% of the amount of the guarantee.  In addition, the Company is
required to purchase credit insurance for all foreign and certain domestic
receivables at a cost of 0.25% of the amount of the insured receivables.

         In January 1995, the Company's United Kingdom subsidiary obtained a
bank line of credit of $300,000 for working capital financing of its projects.
This line of credit is collateralized by a Letter of Credit for $300,000, which
was issued by the Company's primary bank pursuant to the revolving credit
facility described above.  Interest related to borrowings on the United Kingdom
line of credit is charged at a rate per annum equal to the bank's prime rate of
interest plus 1.75%.

         The Company's Canadian subsidiary has a bank line of credit of
approximately $650,000 for working capital financing of its projects.  At
December 31, 1994, the Canadian subsidiary had no





                                      -43-
<PAGE>   44
outstanding borrowings under this arrangement.  Interest related to borrowings
on the Canadian line of credit is charged at a rate per annum equal to the
bank's prime rate of interest plus 1.25%.

CONVERTIBLE DEBENTURES

         On September 30, 1992, the Company sold a $2.5 million 7-year
convertible debenture to Renaissance Capital Partners II, Ltd. ("Renaissance").
Proceeds from the sale of the convertible debenture were used to reduce
accounts payable.  The debenture bears interest at 11% per annum and is
convertible into common stock of the Company at a conversion price of $2.50 per
share.  The conversion price is adjustable if the Company issues significant
additional amounts of common stock for consideration less than the conversion
price of $2.50 per share.  Interest is payable monthly with principal payments
of $25,000 commencing October 1, 1995.

         On September 15, 1993, the Company sold a $1.0 million 7-year
convertible debenture to Renaissance.  Proceeds from the sale of the debenture
were used by the Company for general working capital purposes.  The debenture
bears interest at 11% per annum, payable monthly, and is convertible into
common stock of the Company at a conversion price of $3.25 per share.  The
conversion price is adjustable if the Company issues significant additional
amounts of common stock for consideration less than the conversion price of
$3.25 per share.  The principal of the debenture is payable in 48 equal monthly
installments of $10,000 over a four-year period commencing October 1, 1996 and
ending September 1, 2000, and $520,000 on October 1, 2000.  See Note 2
regarding conversion of a portion of the debentures.

         The financing agreement with Renaissance with respect to the
debentures requires that the Company satisfy certain financial covenants
regarding operating results and financial condition.  As of December 31, 1994,
the Company is not in compliance with certain financial covenants.  Renaissance
has agreed to waive the covenant violations through December 31, 1995.
Renaissance is also entitled to appoint an individual to participate in an
advisory capacity to the Company's Board of Directors as long as $850,000 in
principal amount of the debentures is outstanding.  Commencing on October 1,
1996, the Company has the right at any time upon 90 days prior notice to call
both debentures for redemption.  A call premium applies to such redemption
equal to 15% of the amount redeemed during the fourth year of the debentures,
10% during the fifth year, and 8% thereafter.  During the initial three years
of the debentures, the debentures may be called for redemption at a premium of
20% only if the common stock of the Company has been trading for at least $7.50
per share for 14 trading days prior to the redemption notice and if the Company
has earned at least $.40 per share, in the aggregate, for the last four
consecutive quarters preceding the notice.

         Simultaneously with completion of the Company's June 1994 public
offering of common stock (see Note 2), the Company agreed to change the
conversion price of the $2.5 million and $1.0 million convertible debentures to
$2.67, the average conversion price of both debentures.  Renaissance then
converted $1.75 million in principal amount of the $2.5 million convertible
debentures into 653,846 shares of common stock, which Renaissance sold in the
public offering.  The outstanding balance of $1.75 million consists of a
balance of $750,000 on the original $2.5 million debenture and the $1 million
debenture all of which is convertible at a $2.67 per share.  The Company
reduced paid-in capital by $119,000 for unamortized debt issuance costs related
to the converted debentures.

         At December 31, 1994, the Company had the following net operating
loss, tax credit, and capital loss carry forwards.  Included in the net
operating loss and credit carry forwards are tax benefits from an acquired
company, which can be utilized to offset future taxable income of that acquired
company.

         In addition, the Company has net operating loss carryforwards for U.K.
and Canadian income tax purposes of approximately $12.0 million and $500,000,
respectively.

         During 1992, the Company and the Internal Revenue Service settled a
proposed adjustment of  tax deductions claimed in prior years for amortization
of software acquired in connection with the acquisition of a business.  The
terms of the settlement resulted in a reallocation of acquisition cost for tax
purposes of approximately $4.5 million from software to goodwill, which is not
deductible in computing taxable income.  The Company's net operating loss carry
forwards were reduced by the amount of acquisition cost allocated to goodwill.

NOTE 5 - CAPITAL STOCK

REDEEMABLE PREFERRED STOCK

         In April 1990, Halliburton Company, a major oil and gas services
supplier, invested $3.0 million in a subordinated convertible debenture of the
Company and received non-exclusive rights to market certain of the Company's
new products and to incorporate them into Halliburton's product line.  During
June 1990, following approval by the Company's shareholders for the issuance of
600,000 shares of Series A Redeemable Preferred Stock, par value $5.00 per
share (the "Preferred Stock") the debenture was exchanged for 600,000 shares of
Series A Convertible Preferred Stock.  The preferred stock was convertible into
600,000 shares of common stock.  In September 1990 Halliburton invested an
additional $1.0 million in a convertible debenture of the Company.  In August
1991 the Company's shareholders authorized an additional 600,000 shares of
Preferred Stock and Halliburton exchanged the $1.0 million debenture for
200,000 shares of such stock which were convertible into 200,000 shares of
common stock.  Redemption would have been at the greater of $5.00 per common
share equivalent or the then market price for the Common Stock.

         In the consolidated balance sheet, the Preferred Stock has been
classified outside stockholders' equity in accordance with Rule 5-02.28 of
Regulation S-X, which requires that preferred stock for which redemption may be
required under any conditions beyond control of the issuer be classified
outside of permanent equity.

         In 1994 the Company and Halliburton agreed to amend the conversion and
redemption provisions of the 800,000 shares of the Company's Preferred Stock
held by Halliburton.  As amended, the Preferred Stock is convertible into
300,000 shares of the Company's common stock instead of 800,000 shares prior to
the amendment.  The Company continues to have the right to redeem the Preferred
Stock at any time and also continues to be obligated to do so on the tenth
anniversary of the amendment if the Preferred Stock is still held by
Halliburton.  The Preferred Stock continues to not be entitled to receive or
accrue dividends unless the Company pays dividends on its common stock and as
before the amendment, no interest accrues on the mandatory redemption amount.

joint venture of the Company and Halliburton for the development and marketing
of reservoir monitoring technology and services was terminated and the Company
received a non-exclusive license for the use of certain reservoir monitoring
technology patents.

STOCK OPTION PLANS

         The Board of Directors, at its discretion, may grant options to
purchase shares of the Company's common stock to key employees, officers, and
non-employee members of the Board of Directors.  Prior to 1984 the options were
non-statutory and either vested over a three-year period or were exercisable
at any time for a five or ten-year period after the date of grant or at the
date of amendment of the options.  In 1984 the Company established an incentive
stock option plan for key employees, pursuant to which options to purchase up
to 350,000 shares of Common Stock were reserved for grant.

         In 1993 the Company adopted a stock option plan for non-employee
directors.  Pursuant to the plan, each non-employee director is granted an
option to purchase 5,000 shares of Common Stock upon  initial election to the
board.  Exercise prices are set at the fair market value of the Common Stock on
the date of the grant.  Upon re-election to the Board, for each year to be
served, each non-employee director is granted an option to purchase 2,500
shares of Common Stock at an exercise price set at the fair market value on the
date of the grant.  Pursuant to this plan, options to purchase 12,500 shares at
an exercise price of $4.50 per share were issued  in 1994 and options to
purchase 17,500 shares at an exercise price of $3.50 per share were issued in
1993.

         Following is a summary of stock option activity for the three years
ended December 31, 1994:

CONCENTRATIONS OF CREDIT RISK

         Most of the Company's clients are large, established U.S. and foreign
companies (sometimes acting as government contractors), governments, and
national oil and gas companies of foreign governments.  Qualifying foreign
receivables are insured, subject to a deductible loss amount, under an
insurance policy with the Foreign Credit Insurance Association, an agency of
the United States Export-Import Bank.  The Company performs credit evaluations
of its customers' financial condition when considered necessary and generally
does not require collateral.  In the fourth quarter of 1994 the Company
increased its 1994 provision for doubtful accounts by $5,854,000, of which
$1,958,000 was related to the fixed fee payments due from VARs.  See Note 10 to
the Company's Consolidated Financial Statements.

         At December 31, 1994 and 1993, accounts receivable, net, and work in

NOTE 8 - LEASE COMMITMENTS

         At December 31, 1994, the Company's minimum cash rental commitments
under operating leases for office space and equipment were as follows:


<TABLE>
<CAPTION>
Year                                  Amount
- ----------                        --------------
                                  (In thousands)
<S>                                  <C>
1995                                 $1,515
1996                                  1,322
1997                                  1,029
1998                                    333
1999                                    299
Thereafter                            2,783
</TABLE>




         Total rent expense amounted to $1.4  million in each of 1994, 1993,
and 1992.

         The above minimum cash rental commitments include certain amounts that
have been recorded in the balance sheet as long-term accrued lease obligations
of $720,000 and $1.1 million at December 31, 1994 and 1993, respectively, and
short-term accrued lease obligations of $570,000 and $403,000 at December 31,
1994 and 1993, respectively.  When these amounts are paid, they will be
recorded as a reduction of the accrued lease obligations liability and will not
result in expense in the statement of operations.  The accrued lease
obligations relate to differences in the timing of reportable rental expense
for accounting purposes and the timing of cash receipts and disbursements





                                      -51-
<PAGE>   52
in connection with several office lease transactions.  The accrued lease
obligations will be retired as follows: $616,000 in 1995, $403,000 in 1996,
$288,000 in 1997, and $32,000 in 1998.  These amounts include approximately
$49,000 in interest expense that will be recognized representing the total
discount to present value of accrued lease obligations.

NOTE 9 - CLAIMS AND CONTINGENCIES

         To the knowledge of management, the only claim pending or threatened
against the Company or any of its subsidiaries which individually or
collectively could have a material adverse effect upon the Company or its
financial condition is the following:

         Marshall Wolf, on his behalf and on behalf of all others similarly
situated vs. E. A. Breitenbach, R. J.  Hottovy, Jimmy L. Duckworth, and
Scientific Software-Intercomp, Inc.  On October 5, 1995, a claim was filed in
the United States District Court for the District of Colorado alleging that the
Defendants, who include the President and Chief Executive Officer of the
Company, its Chief Financial Officer and a former Executive Vice President,
violated Section 10(b) of the Securities Exchange Act of 1934 and Rule 10(b)-5
promulgated thereunder in issuing financial reports for the first three
quarters of the Company's 1994 fiscal year which failed to comply with
generally accepted accounting principles with respect to revenues recognized
from the Company's contracts with value added resellers.  The Plaintiff seeks
to have the Court determine that the lawsuit constitutes a proper class action
on behalf of all persons who purchased stock of the Company during the period
from May 30, 1994 through July 10, 1995, with certain exclusions.  The
Company's independent auditors, Ehrhardt Keefe Steiner & Hottman PC, has issued
a report to the Company that the revenues from such contracts were recognized
in accordance with generally accepted accounting principles with the exception
of a $70,000 overstatement of revenue in the first quarter of 1994 which
exception they have concluded was immaterial assuming that the remaining
elements of such quarterly report were in accordance with generally accepted
accounting principles.  Based thereon, it is the opinion of the Company's
counsel that the claim is without merit and it is the intention of the Company
and the other Defendants to vigorously defend the claim.

         Other assets at December 31, 1994 and 1993 includes $470,000 related
to a claim for costs incurred pursuant to a gas pipeline project in India.
Depending on the amount collected on a claim by the primary contractor against
the ultimate customer, the Company could receive up to $1.4 million.  An
allowance for doubtful accounts of $470,000 has been recorded as of December
31, 1994.

         In 1994 the Company settled a lawsuit against Central Hispano Banco
(U.K.) Limited (the "Bank") seeking a declaratory judgment on whether the
Company was liable on the Bank's claim of $473,000 representing unpaid rent
under a computer lease that was assigned to the Bank by the now bankrupt
lessor.  The settlement, which is subject to court approval, did not result in
a material gain or loss.

         The Company's long-term services contracts generally include
provisions for penalty charges for delay in the completion of contracts.
Certain contracts in progress at December 31, 1994 have not been subsequently
completed by the scheduled dates.  Management believes that the delays were not
caused by the Company and that no significant penalties will be incurred.

NOTE 10 - FOURTH QUARTER ADJUSTMENTS

         In the fourth quarter of 1994, certain VARs of the Company's Pipeline
and Facilities division did not pay when due fixed fees for certain software
licensed for use on specific projects for specific customers and also certain
minimum fixed fees for rights of general marketing.  The related transactions
were originally recorded in 1992, 1993 and the first three quarters of 1994.
In the fourth quarter of 1994 the Company increased its 1994 provision for
doubtful accounts by $5,854,000, of which $1,958,000 was related to the fixed
fee payments due from VARs.  The Company has





                                      -52-
<PAGE>   53
determined that the chance is remote that it will be able to collect accounts
receivable of $2,118,000, of which $1,437,000 is related to fixed fee amounts
from VARs, and accordingly, in the December 31, 1994 balance sheet, the Company
has written off accounts receivable totaling $2,118,000.  The Company had
previously filed a Form 10-K with unaudited financial statements for the year
ended December 31, 1994 which showed a fourth quarter provision for doubtful
accounts in the amount of $2,443,000. The increase of $3,411,000 is
attributable to several accounts which the Company has since been unable to
collect and the Company, upon the basis of facts and circumstances subsequent
to the previously filed Form 10-K, has determined that collection of these
amounts is not now imminent.

         The Company commenced and continues to have discussions with VARs that
owe the Company the remaining fixed fees and is in the process of determining
if resolutions acceptable to each VAR and the Company are possible.  The need
of the Company to undertake the foregoing inquiry and the need of its auditors
to await the completion of the inquiry and to undertake their own due diligence
resulted in a substantial delay in completing the audit of the Company's 1994
financial results.

         The Company also recorded adjustments in the fourth quarter of 1994
related to certain fixed-price contracts.  The effect of these adjustments was
to reduce revenue by approximately $300,000.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON
         Accounting and Financial Disclosure

         On September 24, 1993, the Board of Directors of the Company approved
the engagement of Hein + Associates LLP, Denver, Colorado, to audit and report
on the Company's financial statements for the year ended December 31, 1993.  On
August 5, 1993, the Company received the resignation of Ernst & Young, Denver,
Colorado, as the Company's previous auditors.

         The report of Ernst & Young LLP on the Company's financial statements
as of December 31, 1992 and 1991, and for the years then ended, did not contain
any qualifications.  During the fiscal years and any subsequent interim period
preceding the resignation of Ernst & Young, there were no disagreements with
Ernst & Young on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which disagreement, if
not resolved to the satisfaction of the former accountant, would have caused it
to make reference to the subject matter of the disagreement in connection with
its report.

         The Company has provided the former accountant, Ernst & Young, with a
copy of the foregoing disclosures.  A letter, addressed to the Commission, by
the former accountant stating that it agrees with the above statements made by
the Company, was provided to the Commission on August 17, 1993.

         No consultation occurred between the Company and Hein + Associates
during the fiscal years ended December 31, 1992 and 1991 and any subsequent
interim period prior to Hein + Associates' appointment regarding the
application of accounting principles, the type of opinion, or other information
considered by the Company in reaching a decision as to an accounting, auditing,
or financial reporting issue.

On June 30, 1995, the Company was advised by Hein + Associates that it was
resigning as the Company's auditor for its 1994 financial statements although
it was not withdrawing its audit opinion with respect to the Company's 1993
financial statements.  Hein + Associates had not previously discussed the
possibility of resignation during the two month special inquiry period.  Hein +
Associates did not provide the Company with any specific reason or reasons for
its resignation other than to indicate that it was due to a number of factors.
Hein + Associates has however agreed with the Company that such resignation was
not due to any disagreement with the Company over accounting principles or
practices, financial statement disclosure, or auditing scope or procedure.





                                      -54-
<PAGE>   55
         Hein + Associates did not furnish any reason to the Company at the
time of its June 30 resignation or in the July 3 meeting, or with the July 6
communication, for its resignation and declined repeated requests from the
Company and others during the following two weeks for an explanation.  On July
19, 1995 Hein + Associates furnished the Company with a letter advising it that
it had resigned because of a "risk of management misrepresentations" in the
financial statements.  This was the first time any such allegation had been
made throughout the entire investigating period.

         The July 19, 1995 letter of Hein + Associates also indicated that the
timing of adjustments related to the side letters was not resolved at the time
of its resignation.  The Company was however led to believe through its daily
contacts with Hein + Associates that they had in fact reached agreement on the
accounting for the transactions involving the side letters, including the fact
that in mid-June Hein + Associates had approved a final draft of the financial
statements for filing with the SEC, which was then not filed only when the
additional side letter problem involving the Company's former Executive Vice
President was discovered and required analysis.

         On September 22, 1995, the Board of Directors of the Company approved
the selection of Ehrhardt Keefe Steiner & Hottman PC as its auditors.

                                    PART III

         Items 10, 11, 12 and 13 of Part III (except for information required
with respect to executive officers of the Company which is set forth under Item
1, Part I of this report) have been omitted from this report.  The Company has
filed a definitive proxy statement pursuant to Regulation 14A concurrently with
the filing of its initial Annual Report on Form 10-K for the year ended
December 31, 1994.  The information required by Items 10, 11, 12, and 13 of
this report is included in the definitive proxy statement and is incorporated
by reference thereto into Part III of this report.

amount of such Advances or issued standby letters of credit outstanding at any
time does not exceed the Borrowing Base. For Borrowing Base purposes, standby
letters of credit denominated in foreign currencies will be marked up by 20% to
cover currency fluctuations unless hedged with a forward option currency
contract. Any letters of credit prior to the date of shipment of the Items
covered by the subject letter of credit are excluded from the borrowing
availability.  Disbursements shall not be made to finance the cost of
manufacturing or selling of those Items which are to be sold on terms other than
those set forth in Item (7) the Transaction Attachment (Exhibit B).
Disbursements shall not be made (a) except for the purpose of enabling the
Borrower to finance the cost of manufacturing or selling the Items, and (b)
after the Availability Date set forth in item (10) of the Transaction
Attachment. Within the foregoing limits, Borrower may borrow, partially or
wholly prepay, and reborrow under this Agreement as follows.

         CONDITIONS PRECEDENT TO EACH ADVANCE. Lender's obligation to make any
         Advance to or for the account of Borrower and to issue standby letters
         of credit under this Agreement is subject to the following conditions
         precedent, with all documents, instruments, opinions, reports, and
         other items required under this Agreement to be in form and substance
         satisfactory to Lender:

         (a) Lender shall have received evidence that this Agreement and all
         Related Documents have been duly authorized, executed, and delivered by
         Borrower to Lender.

         (b) Lender shall have received such documents, and, if an Event of
         Default has occurred, such opinion of counsel or supplemental opinion
         as Lender may request.

         (c) The security interests in the Collateral shall have been duly
         authorized, created, and perfected with first lien priority and shall
         be in full force and effect.

         (d) All guaranties required by Lender for the Lines of Credit shall
         have   been executed by each Guarantor, delivered to Lender, and be in 
         full force and effect.      
        
         (e) Lender shall have received a 100% guarantee acceptable to Lender
         from the Export-Import Bank of the U.S.  for Lender's export revolving
         line of credit to Borrower. The lack of this guarantee would also
         preclude Lender from extending the domestic revolving line of credit
         (Facility #1).

         (f) Lender, at its option and for its sole benefit, shall have
         conducted an audit of Borrower's Accounts, Inventory, books, records,
         and operations, and Lender shall be satisfied as to their condition.

         (g) Borrower shall have paid or will pay to Lender all fees, costs and
         expenses specified in this Agreement and the Related Documents as are
         then due and payable. Lender will not impose any charge on Borrower in
         connection with this Loan Agreement and the Note(s) other than
         reasonable fees charged by the Lender in accordance with normal
         commercial lending practices.

         (h) There shall not exist at the time of any Advance a condition which
         would constitute an Event of Default under this Agreement.

         MAKING LOAN ADVANCES. Advances under the credit facility, as well as
         directions for payment from Borrower's accounts, may be requested
         orally or in writing by authorized persons. Lender may, but need not,
         require that all oral requests be confirmed in writing. Each Advance
         shall be conclusively deemed to have been made at the request of and
         for the benefit of Borrower (a) when credited to any deposit account
         of Borrower maintained with Lender or (b) when advanced in accordance
         with the instructions of an authorized person. Lender, at its option,
         may set a cutoff time, after which all requests for Advances will be
         treated as having been requested on the next succeeding Business Day.

         MANDATORY LOAN REPAYMENTS/ADDITIONAL COLLATERAL. If at any time the
         aggregate principal amount of the outstanding Advances plus issued
         standby letters of credit shall exceed the applicable Borrowing Base,
         Borrower, immediately upon written or oral notice from Lender shall
         either (a) pay to Lender an amount equal to the difference between the
         outstanding principal balance of the Advances plus issued letters of
         credit and the Borrowing Base or (b) furnish additional security to
         Lender, in form and amount satisfactory to Lender and the Export-
         Import Bank of the U.S.

         LOAN ACCOUNT. Lender shall maintain on its books a record of account
         in which Lender shall make entries for each Advance and such other
         debits and credits as shall be appropriate with the credit facility.
         Lender shall provide Borrower with periodic statements of Borrower's
         accounts, which statements will be considered to be correct and
         conclusively binding on Borrower unless Borrower notifies Lender to
         the contrary with thirty (30) days after Borrower's receipt of any
         such statement which Borrower deems to be incorrect.

REPAYMENT TERM. Provided that the Borrower and any and all Guarantors are not in
default as to the payment of either principal or interest on the Loan, after
all amounts under the Loan Agreement and the Note have been disbursed, all such
amounts shall be due and payable on the Business Day which occurs no later than
the earlier of: (1) the date of the Lender's receipt of all amounts deposited
into the Lender's Account in accordance with the paragraph titled "Lender's
Account" below; or (2) 180 calendar days from the Availability Date.

OPERATING ACCOUNT. Borrower shall utilize a regular operating account. Proceeds
from export sales generated by the United Kingdom and Canadian subsidiaries of

                        SPECIAL CONDITIONS: (AP068039XX)

1.       Cross Default. The Lender and the Borrower shall enter into a loan
         agreement for the Loan which shall include a provision stating that an
         event of default has occurred under the Loan if the Borrower fails to
         pay when due any amount payable to the Lender under any non-Eximbank
         guaranteed loan to the Borrower. It shall further state that, in the
         event of default under the Loan, Eximbank shall have the right to: (i)
         direct the Lender to accelerate the maturities of the Loan; and (ii)
         request that the Lender accelerate the maturities of any of the
         Borrower's non-Eximbank guaranteed loans.

2.       Assignment of Eximbank Export Credit Insurance Policy Proceeds. An
         assignment of the proceeds of the Eximbank Export Credit Insurance
         policy ("Eximbank Policy") opened by the Borrower shall be executed in
         favor of the Lender for the benefit of the Loan. The proceeds of any
         such assignment paid to the Lender shall be applied first towards
         reducing any amount then outstanding under the Loan. The Lender shall
         require that the Borrower notify the Lender and Eximbank in writing
         immediately upon the event of an occurrence under the Eximbank Policy.
         Thereafter, the Lender shall not make any further Disbursements to the
         Borrower under the Loan without the prior written approval of
         Eximbank.

3.       Performance Guarantees. The terms of any and all bid bonds,
         performance bonds, surety bonds, insurance bonds and standby letters
         of credit ("Performance Guarantee,,) are subject to Eximbank's prior
         approval as a condition to their being covered by the Guarantee
         Agreement. Eximbank's Guarantee shall be null and void ab initio with
         respect to any Performance Guarantee which terms conflict with the
         terms and conditions of Eximbank's Guarantee.

4.       Subordinated Non-Eximbank Debt. The Lender shall obtain a written
         undertaking from Renaissance Capital Partners II, Ltd. and the
         Borrower stating that repayment of the principal of the loans owed by
         the Borrower to Renaissance Capital Partners II, Ltd. shall be
         subordinated to repayment by the Borrower of all amounts due and
         outstanding under the Loan.

5.       The Loan may not be used to service any of the Borrower's pre-existing
         or future indebtedness unrelated to the Loan. As a condition precedent
         to the first Disbursement, the Lender shall obtain a written
         undertaking from the Borrower stating that the Loan shall not be
         utilized for the purpose of servicing any of the Borrower's
         pre-existing or future indebtedness unrelated to the Loan.
         Notwithstanding the foregoing, the first Disbursement on the Loan may
         be used to support a single domestic letter of credit, with First
         Interstate Bank of Denver, N.A.(FIBD) as beneficiary, which will, in
         turn, support six (6) export related standby letters of credit issued
         by FIBD under Eximbank guarantee no.

         each country and the funds from these accounts shall be remitted to
         the Lender in the United States on a monthly basis.

9.       Transfer of Controlling Equity Interest. The language of Section 5(j),
         "Transfer of Controlling Equity Interest", of the Guarantee Agreement
         is hereby amended so that the clause "any shares of the borrower's

PRINCIPAL AMOUNT: $5,000,000.00                    INITIAL RATE: 7.750%                DATE OF NOTE: SEPTEMBER 20, 1994
</TABLE>

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC. ("BORROWER") PROMISES TO
PAY TO BANK ONE, BOULDER, N.A.  ("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE
UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF FIVE MILLION & 00/100
DOLLARS ($5,000,000.00) OR SO MUCH AS MAY BE OUTSTANDING, TOGETHER WITH
INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL BALANCE OF EACH ADVANCE. INTEREST
SHALL BE CALCULATED FROM THE DATE OF EACH ADVANCE UNTIL REPAYMENT OF EACH
ADVANCE.

PAYMENT. Borrower will pay this loan in one payment of all outstanding
principal plus all accrued unpaid interest on May 31, 1995. In addition,
Borrower will pay regular monthly payments of accrued unpaid interest beginning
October 31, 1994, and all subsequent interest payments are due on the last day
of each month after that. Interest on this Note is computed on a 365/360 simple
interest basis; that is, by applying the ratio of the annual interest rate over
a year of 360 days, multiplied by the outstanding principal balance, multiplied
by the actual number of days the principal balance is outstanding. Borrower
will pay Lender at Lender's address shown above or at such other place as
Lender may designate in writing. Unless otherwise agreed or required by
applicable law, payments will be applied first to accrued unpaid interest, then
to principal, and any remaining amount to any unpaid collection costs and late
charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change
from time to time based on changes in an index which is the Lender's prime rate
(the "Index"). Prime rate is the Lender's base Lending rate as announced by the
Lender from time to time at its sole discretion. At any given time, the Lender
may make loans at, above, or below its prime rate. Lender will tell Borrower
the current Index rate upon Borrower's request. Borrower understands that
Lender may make loans based on other rates as well. The interest rate change
will not occur more often than each day. The Index currently is 7.750% per
annum. The interest rate to be applied to the unpaid principal  balance of this
Note will be at a rate equal to the Index, resulting in an initial rate of
7.750% per annum. NOTICE: Under no circumstances will the interest rate on this
Note be more than the maximum rate allowed by applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due. Early payments will not, unless agreed to by
Lender in writing, relieve Borrower of Borrower's obligation to continue to
make payments of accrued unpaid interest. Rather, they will reduce the
principal balance due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due.  (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to perform promptly at the time
and strictly in the manner provided in this Note or any agreement related to
this Note, or in any other agreement or loan Borrower has with Lender. (c)
Borrower defaults under any loan, extension of credit, security agreement,
purchase or sales agreement, or any other agreement, in favor of any other
creditor or person that may materially affect any of Borrower's property or
Borrower's ability to repay this Note or perform Borrower's obligations under
this Note or any of the Related Documents. (d) Any representation or statement
made or furnished to Lender by Borrower or on Borrower's behalf is false or
misleading in any material respect. (e) Borrower becomes insolvent, a receiver
is appointed for any part of Borrower's property, Borrower makes an assignment
for the benefit of creditors, or any proceeding is commenced either by Borrower
or against Borrower under any bankruptcy or insolvency laws. (f) Any creditor
tries to take any of Borrower's property on or in which Lender has a lien or
security interest. This includes a garnishment of any of Borrower's accounts
with Lender. (g) Any of the events described in this default section occurs
with respect to any guarantor of this Note.

If any default, other than a default in payment, is curable and if Borrower has
not been given a notice of a breach of the same provision of this Note within
the preceding twelve (12) months, it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender
demanding cure of such default: (a) cures the default within ten (10) days; or
(b) if the cure requires more than ten (10) days, immediately initiates steps
which Lender deems in Lender's sole discretion to be sufficient to cure the
default and thereafter continues and completes all reasonable and necessary
steps sufficient to produce compliance as soon as reasonably practical.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, do one or both of the following: (a) increase the variable
interest rate on this Note to 5.000 percentage points over the Index, and (b)
add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Note (including any increased
rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this Note
if Borrower does not pay. Borrower also will pay Lender that amount. This
includes, subject to any limits under applicable law, Lender's attorneys' fees
and Lender's legal expenses whether or not there is a lawsuit, including
attorneys' fees and legal expenses for bankruptcy proceedings (including
efforts to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgment collection services. If not prohibited by
applicable law, Borrower also will pay any court costs, in addition to all
other sums provided by law. This Note has been delivered to Lender and accepted
by Lender in the State of Colorado. If there is a lawsuit, Borrower agrees upon
Lender's request to submit to the jurisdiction of the courts of Boulder County,
the State of Colorado. Lender and Borrower hereby waive the right to any jury
trial in any action, proceeding, or counterclaim brought by either Lender or
Borrower against the other. This Note shall be governed by and construed in
accordance with the laws of the State of Colorado.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Note against any and all such
accounts.

LINE OF CREDIT. This note evidences a revolving line of credit. Advances under
this Note, as well as directions for payment from Borrower's accounts, may be
requested orally or in writing by Borrower or by an authorized person. Lender
may, but need not, require that all oral requests be confirmed in writing.
Borrower agrees to be liable for all sums either: (a) advanced in accordance
with the instructions of an authorized person or (b) credited to any of
Borrower's accounts with Lender. The unpaid principal balance owing on this Note
at any time may be evidenced by endorsements on this Note or by Lender's
internal records, including daily computer print-outs. Lender will have no
obligation to advance funds under this Note if: (a) Borrower or any guarantor
is in default under the terms of this Note or any agreement that Borrower or
any guarantor has with Lender, including any agreement made in connection with
the signing of this Note; (b) Borrower or any guarantor ceases doing business
or is insolvent; (c) any guarantor seeks, claims or otherwise attempts to
limit, modify or revoke such guarantor's guarantee of this Note or any other
loan with Lender; or (d) Borrower has applied funds provided pursuant to this
Note for purposes other than those authorized by Lender.

GENERAL PROVISIONS. Lender may delay or forgo enforcing any of its rights or
remedies under this Note without losing them. Borrower and any other person who
signs, guarantees or endorses this Note, to the extent allowed by law, waive
presentment, demand for payment, protest and notice of dishonor. Upon any
change in the terms of this Note, and unless otherwise expressly slated in
writing, no party who signs this Note, whether as maker, guarantor,
accommodation maker or endorser, shall be released from liability. All such
parties agree that Lender may renew or extend (repeatedly and for any length of
time) this loan, or release any party or guarantor or collateral; or impair,
fail to realize upon or perfect Lender's security interest in the collateral;
and take any other action deemed necessary by Lender without the consent of or
notice to anyone. All such parties also agree that Lender may modify this loan
without the consent of or notice to anyone other than the party with whom the
modification is made.

PAY TO BANK ONE, BOULDER, N.A.  ("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE
UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF ONE MILLION FIVE HUNDRED 
THOUSAND AND 00/100 DOLLARS ($1,500,000.00) OR SO MUCH AS MAY BE OUTSTANDING, 
TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL BALANCE OF EACH 
ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH ADVANCE UNTIL 
REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON MAY 31, 1995. In addition,
Borrower will pay regular monthly payments of accrued unpaid interest beginning
October 31, 1994, and all subsequent interest payments are due on the last day
of each month after that. Interest on this Note is computed on a 365/360 simple
interest basis; that is, by applying the ratio of the annual interest rate over
a year of 360 days, multiplied by the outstanding principal balance, multiplied
by the actual number of days the principal balance is outstanding. Borrower
will pay Lender at Lender's address shown above or at such other place as
Lender may designate in writing. Unless otherwise agreed or required by
applicable law, payments will be applied first to accrued unpaid interest, then
to principal, and any remaining amount to any unpaid collection costs and late
charges.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change
from time to time based on changes in an index which is the Lender's prime rate
(the "Index"). Prime rate is the Lender's base Lending rate as announced by the
Lender from time to time at its sole discretion. At any given time, the Lender
may make loans at, above, or below its prime rate. Lender will tell Borrower
the current Index rate upon Borrower's request. Borrower understands that
Lender may make loans based on other rates as well. The interest rate change
will not occur more often than each day. The Index currently is 7.750% per
annum. The interest rate to be applied to the unpaid principal balance of this
Note will be at a rate of 1.500 percentage points over the Index, resulting in 
an initial rate of 9.250% per annum. NOTICE: Under no circumstances will the 
interest rate on this Note be more than the maximum rate allowed by applicable 
law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due. Early payments will not, unless agreed to by
Lender in writing, relieve Borrower of Borrower's obligation to continue to
make payments of accrued unpaid interest. Rather, they will reduce the
principal balance due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to perform promptly at the time
and strictly in the manner provided in this Note or any agreement related to
this Note, or in any other agreement or loan Borrower has with Lender. (c)
Borrower defaults under any loan, extension of credit, security agreement,
purchase or sales agreement, or any other agreement, in favor of any other
creditor or person that may materially affect any of Borrower's property or
Borrower's ability to repay this Note or perform Borrower's obligations under
this Note or any of the Related Documents. (d) Any representation or statement
made or furnished to Lender by Borrower or on Borrower's behalf is false or
misleading in any material respect. (e) Borrower becomes insolvent, a receiver
is appointed for any part of Borrower's property, Borrower makes an assignment
for the benefit of creditors, or any proceeding is commenced either by Borrower
or against Borrower under any bankruptcy or insolvency laws. (f) Any creditor
tries to take any of Borrower's property on or in which Lender has a lien or
security interest. This includes a garnishment of any of Borrower's accounts
with Lender. (g) Any of the events described in this default section occurs
with respect to any guarantor of this Note.

If any default, other than a default in payment, is curable and if Borrower has
not been given a notice of a breach of the same provision of this Note within
the preceding twelve (12) months, it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender
demanding cure of such default: (a) cures the default within ten (10) days, or
(b) if the cure requires more than ten (10) days, immediately initiates steps
which Lender deems in Lender's sole discretion to be sufficient to cure the
default and thereafter continues and completes all reasonable and necessary
steps sufficient to produce compliance as soon as reasonably practical.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, do one or both of the following: (a) increase the variable
interest rate on this Note to 5.000 percentage points over the Index, and (b)
add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Note (including any increased
rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this Note
if Borrower does not pay. Borrower also will pay Lender that amount. This
includes, subject to any limits under applicable law, Lender's attorneys' fees
and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including
efforts to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by
applicable law, Borrower also will pay any court costs, in addition to all
other sums provided by law. This Note has been delivered to Lender and accepted
by Lender in the State of Colorado. If there is a lawsuit, Borrower agrees upon
Lender's request to submit to the jurisdiction of the courts of Boulder County,
the State of Colorado. Lender and Borrower hereby waive the right to any jury
trial in any action, proceeding, or counterclaim brought by either Lender or
Borrower against the other. This Note shall be governed by and construed in
accordance with the laws of the State of Colorado.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Note against any and all such
accounts.

LINE OF CREDIT. This note evidences a revolving line of credit. Advances under
this Note, as well as directions for payment from Borrower's accounts, may be
requested orally or in writing by Borrower or by an authorized person. Lender
may, but need not, require that all oral requests be confirmed in writing.
Borrower agrees to be liable for all sums either: (a) advanced in accordance
with the instructions of an authorized person or (b) credited to any of
Borrower's account with Lender. The unpaid principal balance owing on this Note
at any time may be evidenced by endorsements on this Note or by Lender's
internal records, including daily computer print-outs. Lender will have no
obligation to advance funds under this Note if: (a) Borrower or any guarantor
is in default under the terms of this Note or any agreement that Borrower or
any guarantor has with Lender, including any agreement made in connection with
the signing of this Note; (b) Borrower or any guarantor ceases doing business
or is insolvent; (c) any guarantor seeks, claims or otherwise attempts to
limit, modify or revoke such guarantor's guarantee of this Note or any other
loan with Lender; or (d) Borrower has applied funds provided pursuant to this
Note for purposes other than those authorized by Lender.

GENERAL PROVISIONS. Lender may delay or forgo enforcing any of its rights or
remedies under this Note without losing them. Borrower and any other person who
signs, guarantees or endorses this Note, to the extent allowed by law, waive
presentment, demand for payment, protest and notice of dishonor. Upon any
change in the terms of this Note, and unless otherwise expressly slated in
writing, no party who signs this Note, whether as maker, guarantor,
accommodation maker or endorser, shall be released from liability. All such
parties agree that Lender may renew or extend (repeatedly and for any length of
time) this loan, or release any party or guarantor or collateral; or impair,
fail to realize upon or perfect Lender's security interest in the collateral;
and take any other action deemed necessary by Lender without the consent of or
notice to anyone. All such parties also agree that Lender may modify this loan
without the consent of or notice to anyone other than the party with whom the
modification is made.

this Agreement, Borrower understands that Lender is entitled to a MINIMUM

Agreement or any agreement related to this Agreement, or in any other agreement
or loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 5% over Index per annum, and (b)
add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Agreement (including any
increased rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this
Agreement if Borrower does not pay. Borrower also will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed in
writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will have
no obligation to advance funds under this Agreement if: (a) Borrower or any
guarantor is in default under the terms of this Agreement or any agreement that
Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of this
Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms of
the original obligation or obligations, including all agreements evidenced or
securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a satisfaction
of the obligation(s). It is the intention of Lender to retain as liable parties
all makers and endorsers of the original obligation(s), including accommodation
parties, unless a party is expressly released by Lender in writing. Any maker or
endorser, including accommodation makers, will not be released by virtue of this
Agreement. If any person who signed the original obligation does not sign this
Agreement below, then all persons signing below acknowledge that this Agreement
is given conditionally, based on the representation to Lender that the
non-signing party consents to the changes and provisions of this Agreement or
otherwise will not be released by it. This waiver applies not only to any
initial extension, modification or release, but also to all such subsequent

</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994, IN THE ORIGINAL PRINCIPAL AMOUNT OF $1,500,000.00.

DESCRIPTION OF CHANGE IN TERMS: MATURITY DATE WILL NOW BE JULY 15, 1995.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("Borrower") promises to pay to BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF ONE
MILLION FIVE HUNDRED THOUSAND & 00/100 DOLLARS ($1,500,000.00) OR SO MUCH AS
MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON JULY 15, 1995. Interest on this
Agreement is computed on a 365/360 simple interest basis; that is, by applying
the ratio of the annual interest rate over a year of 360 days, multiplied by
the outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's address
shown above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied first
to accrued unpaid interest, then to principal, and any remaining amount to any
unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 9.000% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 1.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 10.500% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Note be more than
the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum 
interest charge, Borrower may pay without penalty all or a portion of the 
amount owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due.  (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
of loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 5% over Index per annum, and (b)
add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Agreement (including any
increased rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this
Agreement if Borrower does not pay. Borrower also will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's account with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms of
the original obligation or obligations, including all agreements evidenced or
securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a satisfaction
of the obligation(s). It is the intention of Lender to retain as liable parties
all makers and endorsers of the original obligation(s), including accommodation
parties, unless a party is expressly released by Lender in writing. Any maker or
endorser, including accommodation makers, will not be released by virtue of this
Agreement. If any person who signed the original obligation does not sign this
Agreement below, then all persons signing below acknowledge that this Agreement
is given conditionally, based on the representation to Lender that the
non-signing party consents to the changes and provisions of this Agreement or
otherwise will not be released by it. This waiver applies not only to any
initial extension, modification or release, but also to all such subsequent
actions.

change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 1.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 10.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be 
more than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum 
interest charge, Borrower may pay without penalty all or a portion of the 
amount owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
of loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 25.000%  per annum, and (b) add
any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Agreement (including any 
increased rate). The interest rate will not exceed the maximum rate permitted 
by applicable law. Lender may hire or pay someone else to help collect this 
Agreement if Borrower does not pay. Borrower also will pay Lender that amount. 
This includes, subject to any limits under applicable law, Lender's attorneys' 
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including
efforts to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

MILLION FIVE HUNDRED THOUSAND & 00/100 DOLLARS ($1,500,000.00) OR SO MUCH AS
MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL

ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON AUGUST 15, 1995. Interest on this
Agreement is computed on a 365/360 simple interest basis; that is, by applying
the ratio of the annual interest rate over a year of 360 days, multiplied by
the outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's address
shown above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied first
to accrued unpaid interest, then to principal, and any remaining amount to any

change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 2.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 11.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be more
than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum
interest charge, Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due.  (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this
Agreement, or any agreement related to this Agreement, or in any other agreement
of loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 25.000%  per annum, and (b) add
any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Agreement (including any
increased rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this
Agreement if Borrower does not pay. Borrower also will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed in
writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will have
no obligation to advance funds under this Agreement if: (a) Borrower or any
guarantor is in default under the terms of this Agreement or any agreement that
Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of this
Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms of
the original obligation or obligations, including all agreements evidenced or
securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a satisfaction
of the obligation(s). It is the intention of Lender to retain as liable parties
all makers and endorsers of the original obligation(s), including accommodation
parties, unless a party is expressly released by Lender in writing. Any maker or
endorser, including accommodation makers, will not be released by virtue of this
Agreement. If any person who signed the original obligation does not sign this
Agreement below, then all persons signing below acknowledge that this Agreement
is given conditionally, based on the representation to Lender that the
non-signing party consents to the changes and provisions of this Agreement or
otherwise will not be released by it. This waiver applies not only to any
initial extension, modification or release, but also to all such subsequent
actions.

</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $5,000,000.00.

DESCRIPTION OF CHANGE IN TERMS: THE MATURITY DATE WILL NOW BE SEPTEMBER 15,
1995. SEE BELOW FOR NEW PAYMENT SCHEDULE. THIS REVOLVING LINE OF CREDIT IS
HEREBY CAPPED AT $4,500,000.00.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("BORROWER") PROMISES TO PAY TO BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF FOUR
MILLION FIVE HUNDRED THOUSAND & 00/100 DOLLARS ($4,500,000.00) OR SO MUCH AS
MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON SEPTEMBER 15, 1995. Interest on
this Agreement is computed on a 365/360 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate
in writing. Unless otherwise agreed or required by applicable law, payments
will be applied first to accrued unpaid interest, then to principal, and any
remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 1.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 10.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Note be more than
the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. Borrower agrees that all loan fees and
other prepaid finance charges are earned fully as of the date of the loan and
will not be subject to refund upon early payment (whether voluntary or as a
result of default), except as otherwise required by law. In any event, even
upon full prepayment of this Agreement, Borrower understands that Lender is
entitled to a MINIMUM INTEREST CHARGE OF $25.00. Other than Borrower's
obligation to pay any minimum interest charge, Borrower may pay without penalty
all or a portion of the amount owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform 
when due any other term, obligation, covenant, or condition contained in this 
Agreement or any agreement related to this Agreement, or in any other agreement
or loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor
tries to take any of Borrower's property on or in which Lender has a lien or
security interest. This includes a garnishment of any of Borrower's accounts
with Lender. (g) Any of the events described in this default section occurs
with respect to any guarantor of this Agreement. (h) A material adverse change
occurs in Borrower's financial condition, or Lender believes the prospect of
payment or performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 25.000% per annum, and (b) add
any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Note (including any increased
rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this
Agreement if Borrower does not pay. Borrower also will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $1,500,000.00.

DESCRIPTION OF CHANGE IN TERMS. THE MATURITY DATE WILL NOW BE SEPTEMBER 15,
1995. SEE BELOW FOR NEW PAYMENT SCHEDULE.  THIS REVOLVING LINE OF CREDIT IS
HEREBY CAPPED AT $633,000.00.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("Borrower") promises to pay to BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF SIX
HUNDRED THIRTY THREE THOUSAND & 00/100 DOLLARS ($633,000.00) OR SO MUCH AS MAY
BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON AUGUST 15, 1995. Interest on this
Agreement is computed on a 365/360 simple interest basis; that is, by applying
the ratio of the annual interest rate over a year of 360 days, multiplied by
the outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's address
shown above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied first
to accrued unpaid interest, then to principal, and any remaining amount to any
unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 2.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 11.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be 
more than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum
interest charge, Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due.  (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
of loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 25.000% per annum, and (b) add
any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Agreement (including any
increased rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this
Agreement if Borrower does not pay. Borrower also will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Note or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

MISCELLANEOUS PROVISIONS. Lender may delay or forgo enforcing any of its rights
or remedies under this Agreement without losing them. Borrower and any other
person who signs, guarantees or endorses this Agreement, to the extent allowed
by law, waive presentment, demand for payment, protest and notice of dishonor.
Upon any change in the terms of this Agreement, and unless otherwise expressly
stated in writing, no party who signs this Agreement, whether as maker,
guarantor, accommodation maker or endorser, shall be released from liability.
All such parties agree that Lender may renew or extend (repeatedly and for any
length of time) this loan, or release any party or guarantor or collateral; or
impair, fail to realize upon or perfect Lender's security interest in the
collateral; and take any other action deemed necessary by Lender without the
consent of or notice to anyone. All such parties also agree that Lender may

</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $5,000,000.00.

DESCRIPTION OF CHANGE IN TERMS: THE MATURITY DATE WILL NOW BE SEPTEMBER 15,
1995.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("BORROWER") PROMISES TO PAY TO BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF FOUR
MILLION FIVE HUNDRED THOUSAND & 00/100 DOLLARS ($4,500,000.00) OR SO MUCH AS
MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON SEPTEMBER 15, 1995. Interest on
this Agreement is computed on a 365/360 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate
in writing. Unless otherwise agreed or required by applicable law, payments
will be applied first to accrued unpaid interest, then to principal, and any
remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 1.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 10.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be 
more than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum 
interest charge, Borrower may pay without penalty all or a portion of the 
amount owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
or loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 5.00% over the Index, and (b)
add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Agreement (including any 
increased rate). The interest rate will not exceed the maximum rate permitted 
by applicable law. Lender may hire or pay someone else to help collect this 
Agreement if Borrower does not pay. Borrower also will pay Lender that amount. 
This includes, subject to any limits under applicable law, Lender's attorneys' 
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including
efforts to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 5.00% over the Index, and (b)

LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER AGREES UPON

THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by

that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $5,000,000.00.

DESCRIPTION OF CHANGE IN TERMS: THE MATURITY DATE WILL NOW BE OCTOBER 15, 1995.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("BORROWER") PROMISES TO PAY TO BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF FOUR
MILLION FIVE HUNDRED THOUSAND & 00/100 DOLLARS ($4,500,000.00) OR SO MUCH AS
MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON OCTOBER 15, 1995. Interest on
this Agreement is computed on a 365/360 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate
in writing. Unless otherwise agreed or required by applicable law, payments
will be applied first to accrued unpaid interest, then to principal, and any
remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender
will tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL  BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 1.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 10.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be more
than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum
interest charge, Borrower may pay without penalty all or a portion of the
amount owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform
when due any other term, obligation, covenant, or condition contained in this 
Agreement or any agreement related to this Agreement, or in any other agreement
of loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor
tries to take any of Borrower's property on or in which Lender has a lien or
security interest. This includes a garnishment of any of Borrower's accounts
with Lender. (g) Any of the events described in this default section occurs
with respect to any guarantor of this Agreement. (h) A material adverse change
occurs in Borrower's financial condition, or Lender believes the prospect of
payment or performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 5.00% over the Index per annum,
and (b) add any unpaid accrued interest to principal and such sum will bear
interest therefrom until paid at the rate provided in this Agreement (including
any increased rate). The interest rate will not exceed the maximum rate
permitted by applicable law.  Lender may hire or pay someone else to help
collect this Agreement if Borrower does not pay. Borrower also will pay Lender
that amount. This includes, subject to any limits under applicable law,
Lender's attorneys' fees and Lender's legal expenses whether or not there is a
lawsuit, including attorneys' fees and legal expenses for bankruptcy
proceedings (including efforts to modify or vacate any automatic stay or
injunction), appeals, and any anticipated post-judgement collection services.
If not prohibited by applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law. THIS AGREEMENT HAS BEEN DELIVERED
TO LENDER AND ACCEPTED BY LENDER IN THE STATE OF COLORADO.  IF THERE IS A
LAWSUIT, BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF
THE COURTS OF BOULDER COUNTY, THE STATE OF COLORADO. LENDER AND BORROWER HEREBY
WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM
BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

PRINCIPAL AMOUNT: $633,000.00                                                      DATE OF AGREEMENT: SEPTEMBER 30, 1995
</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $1,500,000.00.

DESCRIPTION OF CHANGE IN TERMS: THE MATURITY DATE WILL NOW BE OCTOBER 15, 1995.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("BORROWER") PROMISES TO PAY TO BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF SIX
HUNDRED THIRTY THREE THOUSAND & 00/100 DOLLARS ($633,000.00) OR SO MUCH AS MAY
BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON OCTOBER 15, 1995. Interest on
this Agreement is computed on a 365/360 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate
in writing. Unless otherwise agreed or required by applicable law, payments
will be applied first to accrued unpaid interest, then to principal, and any
remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 2.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 11.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be more
than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum 
interest charge, Borrower may pay without penalty all or a portion of the 
amount owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due.  (b) Borrower breaks any
promise Borrower has made to Lender, or Borrower fails to comply with or to
perform when due any other term, obligation, covenant, or condition contained in
this Agreement or any agreement related to this Agreement, or in any other
agreement of loan Borrower has with Lender. (c) Borrower defaults under any
loan, extension of credit, security agreement, purchase or sales agreement, or
any other agreement, in favor of any other creditor or person that may
materially affect any of Borrower's property or Borrower's ability to repay this
Note or perform Borrower's obligations under this Note or any of the Related
Documents. (d) Any representation or statement made or furnished to Lender by
Borrower or on Borrower's behalf is false or misleading in any material respect
either now or at the time made or furnished. (e) Borrower becomes insolvent, a
receiver is appointed for any part of Borrower's property, Borrower makes an
assignment for the benefit of creditors, or any proceeding is commenced either
by Borrower or against Borrower under any bankruptcy or insolvency laws. (f) Any
creditor tries to take any of Borrower's property on or in which Lender has a
lien or security interest. This includes a garnishment of any of Borrower's
accounts with Lender. (g) Any of the events described in this default section
occurs with respect to any guarantor of this Agreement. (h) A material adverse
change occurs in Borrower's financial condition, or Lender believes the prospect
of payment or performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 5.0% over the Index per annum,
and (b) add any unpaid accrued interest to principal and such sum will bear
interest therefrom until paid at the rate provided in this Agreement (including
any increased rate). The interest rate will not exceed the maximum rate
permitted by applicable law.  Lender may hire or pay someone else to help
collect this Agreement if Borrower does not pay. Borrower also will pay Lender
that amount. This includes, subject to any limits under applicable law, Lender's
attorneys' fees and Lender's legal expenses whether or not there is a lawsuit,
including attorneys' fees and legal expenses for bankruptcy proceedings
(including efforts to modify or vacate any automatic stay or injunction),
appeals, and any anticipated post-judgement collection services. If not
prohibited by applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO
LENDER AND ACCEPTED BY LENDER IN THE STATE OF COLORADO.  IF THERE IS A LAWSUIT,
BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE
COURTS OF BOULDER COUNTY, THE STATE OF COLORADO. LENDER AND BORROWER HEREBY
WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM
BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's account with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

         precedent, with all documents, instruments, opinions, reports, and
         other items required under this Agreement to be in form and substance
         satisfactory to Lender:

         (a) Lender shall have received evidence that this Agreement and all
         Related Documents have been duly authorized, executed, and delivered by
         Borrower to Lender.

         (b) Lender shall have received such documents, and, if an Event of
         Default has occurred, such opinion of counsel or supplemental opinion
         as Lender may request.

         (c) The security interests in the Collateral shall have been duly

         from the Export-Import Bank of the U.S. for Lender's export revolving
         line of credit to Borrower. The lack of this guarantee would also
         preclude Lender from extending the domestic revolving line of credit
         (Facility #1).

         (f) Lender, at its option and for its sole benefit, shall have
         conducted an audit of Borrower's Accounts, Inventory, books, records,
         and operations, and Lender shall be satisfied as to their condition.

         (g) Borrower shall have paid or will pay to Lender all fees, costs and
         expenses specified in this Agreement and the Related Documents as are
         then due and payable. Lender will not impose any charge on Borrower in
         connection with this Loan Agreement and the Note(s) other than
         reasonable fees charged by the Lender in accordance with normal
         commercial lending practices.

         (h) There shall not exist at the time of any Advance a condition which
         would constitute an Event of Default under this Agreement.

         MAKING LOAN ADVANCES. Advances under the credit facility are
restricted solely to the export revolving line of credit guaranteed by the
Export-Import Bank of the U.S. Advances, as well as directions for payment from
Borrower's accounts, may be requested orally or in writing by authorized
persons. Lender may, but need not, require that all oral requests be confirmed
in writing. Each Advance shall be conclusively deemed to have been made at the
request of and for the benefit of Borrower (a) when credited to any deposit
account of Borrower maintained with Lender or (b) when advanced in accordance
with the instructions of an authorized person. Lender, at its option, may set a
cutoff time, after which all requests for Advances will be treated as having
been requested on the next succeeding Business Day.

         MANDATORY LOAN REPAYMENTS/ADDITIONAL COLLATERAL. If at any time the
         aggregate principal amount of the outstanding Advances plus issued
         standby letters of credit shall exceed the applicable Borrowing Base,
         Borrower, immediately upon written or oral notice from Lender shall
         either (a) pay to Lender an amount equal to the difference between the
         outstanding principal balance of the Advances plus issued letters of
         credit and the Borrowing Base or (b) furnish additional security to

         in which Lender shall make entries for each Advance and such other
         debits and credits as shall be appropriate with the credit facility.
         Lender shall provide Borrower with periodic statements of Borrower's
         accounts, which statements will be considered to be correct and
         conclusively binding on Borrower unless Borrower notifies Lender to
         the contrary with thirty (30) days after Borrower's receipt of any
         such statement which Borrower deems to be incorrect.

OPERATING ACCOUNT. Borrower shall utilize a regular operating account with
Lender. 

COLLATERAL. To secure payment of the Lines of Credit and performance of all
other Loans, obligations and duties owed by Borrower to lender, Borrower (and
others, if required) shall grant to Lender Security Interests in such property
and assets as Lender may require (the "Collateral"), including without
limitation Borrower's present and future Accounts, contract rights, general

become a lien or charge upon any of Borrowers properties, income, or profits.

without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable

such accounts. However, the Lender's right of setoff will be limited to
Borrower's pro-rata share of any joint venture equity interest.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

         DEFAULT ON INDEBTEDNESS. Failure of Borrower to make any payment when
due on the Loans.

         OTHER DEFAULTS. Failure of Borrower or any Grantor to comply with or
to perform when due any other term, obligation, covenant or condition contained
in this Agreement or in any of the Related Documents, or failure of Borrower to
comply with or to perform any other term, obligation, covenant or condition
contained in any other agreement between Lender and Borrower ten (10) days
after receiving written notice from Lender demanding cure of such default. If
the cure requires more than ten (10) days, Borrower shall immediately initiate
steps which Lender deems in Lender's sole discretion to be sufficient to cure
the default and thereafter shall continue and complete all reasonable and
necessary steps sufficient to produce compliance as soon as reasonably
practical.

         DEFAULT IN FAVOR OF THIRD PARTIES. Should Borrower or any Grantor
default under any loan, extension of credit, security agreement, purchase or
sales agreement, or any other agreement, in favor of any other creditor or
person that may materially affect any of Borrower's property or Borrower's or
any Grantor's ability to repay the Loans or perform their respective
obligations under this Agreement or any of the Related Documents.

         FALSE STATEMENTS. Any warranty, representation, or statement made or

Agreement or the Related Documents is false or misleading in any material
respect, either now or at the time made or furnished.

         DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related
Documents ceases to be in full force and effect (including failure of any
Security Agreement to create a valid and perfected Security interest) at any
time and for any reason.

         INSOLVENCY. Any dissolution or termination of Borrower's existence as
a going business, insolvency, appointment of a receiver for any part of
Borrower's property, any assignment for the benefit of creditors, any type of
creditor workout, or the commencement of any proceeding under any bankruptcy or
insolvency laws by or against Borrower.

         CREDITOR OR FORFEITURE PROCEEDING. Commencement of foreclosure or
forfeiture proceedings, 



                                       7

<PAGE>   8

whether by judicial proceeding, self-help, repossession or any other method, by
any creditor of Borrower, any creditor of any Grantor against any collateral
securing the indebtedness, or by any governmental agency. This includes a
garnishment, attachment, or levy on or of any of Borrower's deposit accounts
with Lender.

         CHANGE IN OWNERSHIP. Any single change in ownership of twenty-five
percent (25%) or more of the common stock of Borrower.

         ADVERSE CHANGE. A material adverse change occurs in Borrower's
financial condition, or Lender believes the prospect of payment or performance
of the indebtedness is impaired.

EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, all 
commitments and obligations of Lender under this agreement or the Related 
Documents or any other agreement immediately will terminate (including any 
obligation to make Loan Advances or disbursements), and, at Lender's option, 
all Loans immediately will become due and payable except that in the case of an 
Event of Default of the type described in the "insolvency" subsection above,
such acceleration shall be automatic and not optional.

NOTICE IN EVENT OF FILING OF ACTION FOR DEBTOR'S RELIEF. The Borrower shall
promptly notify the Lender in writing of the occurrence of any of the
following: (1) the Borrower begins or consents in any manner to any proceeding
or arrangement for its liquidation in whole or in Part or to any other
proceeding or arrangement whereby any of its assets are subject generally to
the payment of its liabilities or whereby any receiver, trustee, liquidator or
the like is appointed for it or any substantial part of its assets (including
without limitation the filing by the Borrower of a petition for appointment as
a debtor-in-possession under Title 11 of the U.S. Code); (2) the Borrower fails
to obtain the dismissal or stay on appeal within thirty (30) calendar days of
the commencement of any proceeding arrangement referred to in (1) above; (3)
the Borrower begins any other procedure for the relief of financially
distressed or insolvent debtors, or such procedure has been commenced against
it, whether voluntarily or involuntarily, and such procedure has not been
effectively terminated, dismissed or stayed within thirty (30) calendar days
after the commencement thereof, or (4) the Borrower begins any procedure for
its dissolution, or a procedure therefore has been commenced against it.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

         AMENDMENTS. This Agreement, together with any Related Documents,
constitutes the entire understanding and agreement of the parties as to the
matters set forth in this Agreement. No alteration of or amendment to this
Agreement shall be effective unless given in writing and signed by the party or
parties sought to be charged or bound by the alteration or amendment.

         APPLICABLE LAW. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND
ACCEPTED BY LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT, BORROWER
AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF
BOULDER COUNTY, THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE
RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY
EITHER LENDER OR BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

         CAPTION HEADINGS. Caption headings in this Agreement are for
convenience purposes only and are not to be used to interpret or define the
provisions of this Agreement.

         MULTIPLE PARTIES. All obligations of Borrower under this Agreement
shall be joint and several, and all references to Borrower shall mean each and
every Borrower. This means that each of the persons signing below is
responsible for all obligations in this Agreement.

         COSTS AND EXPENSES. Borrower agrees to pay upon demand all of Lender's
out-of-pocket expenses, including reasonable attorneys' fees, incurred in
connection with the preparation, execution, enforcement and collection of this
Agreement or in connection with the Loans made pursuant to this Agreement.
Lender may pay someone else to help collect the Loans and to enforce this
Agreement, and Borrower will pay that amount. This includes, subject to any
limits under applicable law, Lender's attorney's fees and Lender's legal
expenses, whether or not there is a lawsuit, including attorney's fees for
bankruptcy proceedings (including efforts to modify or vacate any automatic
stay or injunction), appeals, and any anticipated post-judgment collection
services. Borrower also will pay any court costs, in addition to all other sums
provided by law.

         NOTICES. All notices required to be given under this Agreement shall
be effective when actually delivered or when deposited with a nationally
recognized overnight courier or deposited in the United States mail, first
class, postage prepaid, addressed to the party to whom the notice is to be
given at the address shown above. Any party may change its address for notices
under this Agreement by giving formal written notice to the other parties,
specifying that the purpose of the notice is to change the party's address. To
the extent permitted by Applicable law, if there is more than one Borrower,
notice to any Borrower will constitute notice to all Borrowers. For notice
purposes, Borrower agrees to keep Lender informed at all times of Borrower's
current address(es).

         SEVERABILITY. If a court of competent jurisdiction finds any provision
of the Agreement to be invalid or unenforceable as to any person or
circumstance, such finding shall not render that provision invalid or
unenforceable as to any other persons or circumstances. If feasible, any such
offending provision shall be deemed to be modified to be within the limits of
enforceability or validity; however, if the offending provision cannot be so
modified, it shall be stricken and all other provisions of this Agreement in
all other respects shall remain valid and enforceable.

         SUBSIDIARIES AND AFFILIATES. To the extent the context of any
provisions of this Agreement makes it appropriate, including without limitation
any representation, warranty or covenant, the word "Borrower" as used herein
shall include all subsidiaries of Borrower, with the exception of its Canadian
subsidiary, IRDE. Notwithstanding the foregoing however, under no circumstances
shall this Agreement be construed to require Lender to make any Loan or other
financial accommodation to any subsidiary of Borrower.

         SUCCESSORS AND ASSIGNS. All covenants and agreements contained by or
on behalf of Borrower shall bind its successors and assigns and shall inure to
the benefit of Lender, its successors and assigns. Borrower shall not, however,
have the right to assign its rights under this Agreement or any interest
therein, without the prior written consent of Lender.

         SURVIVAL. All warranties, representations, and covenants made by
Borrower in this Agreement or in any certificate or other instrument delivered
by Borrower to Lender under this Agreement shall be considered to have been
relied upon by Lender and will survive the making of the Loan and delivery to
Lender of the Related Documents, regardless of any investigation made by Lender
or on Lender's behalf.

         TIME IS OF THE ESSENCE. Time is of the essence in the performance of
this Agreement.


                                       8

         Waiver. Lender shall not be deemed to have waived any rights under
this Agreement unless such waiver is given in writing and signed by Lender. No
delay or omission on the part of Lender in exercising any right shall operate
as a waiver of such right or any other right. A waiver by Lender of a provision
of this Agreement shall not prejudice or constitute a waiver of Lender's right
otherwise to demand strict compliance with that provision or any other
provision of this Agreement. No prior waiver by Lender, nor any course of
dealing between Lender and Borrower, or between Lender and any Grantor, shall
constitute a waiver of any of Lender's rights or of any obligations of Borrower
or of any Grantor as to any future transactions. Whenever the consent of Lender
is required under this Agreement, the granting of such consent by Lender in any
instance shall not constitute continuing consent in subsequent instances where 
such consent is required and in all cases such consent may be granted or 
withheld in the sole discretion of Lender.

AGREEMENT, AND BORROWER AGREES TO ITS TERMS. THIS AGREEMENT IS DATED AS OF

PRINCIPAL AMOUNT: $4,500,000.00                                                      DATE OF AGREEMENT: OCTOBER 15, 1995
</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $5,000,000.00.

DESCRIPTION OF CHANGE IN TERMS: THE MATURITY DATE WILL NOW BE MARCH 30, 1996.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("BORROWER") PROMISES TO PAY TO BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF FOUR
MILLION FIVE HUNDRED THOUSAND & 00/100 DOLLARS ($4,500,000.00) OR SO MUCH AS
MAY BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON MARCH 30, 1996. IN ADDITION,
BORROWER WILL PAY REGULAR MONTHLY PAYMENTS OF ACCRUED UNPAID INTEREST BEGINNING
NOVEMBER 30, 1995, AND ALL SUBSEQUENT INTEREST PAYMENTS ARE DUE ON THE SAME DAY
OF EACH MONTH AFTER THAT. Interest on this Agreement is computed on a 365/360
simple interest basis; that is, by applying the ratio of the annual interest
rate over a year of 360 days, multiplied by the outstanding principal balance,
multiplied by the actual number of days the principal balance is outstanding.
Borrower will pay Lender at Lender's address shown above or at such other place
as Lender may designate in writing. Unless otherwise agreed or required by
applicable law, payments will be applied first to accrued unpaid interest, then
to principal, and any remaining amount to any unpaid collection costs and late
charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY. THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 1.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 10.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Note be more than
the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum
interest charge, Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due. Early payments will not, unless agreed to by Lender
in writing, relieve Borrower of Borrower's obligation to continue to make
payments of accrued unpaid interest. Rather, they will reduce the principal
balance due.

     DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, convenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
or loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to Prime Rate plus 5% per annum,
and (b) add any unpaid accrued interest to principal and such sum will bear
interest therefrom until paid at the rate provided in this Agreement (including
any increased rate). The interest rate will not exceed the maximum rate
permitted by applicable law.  Lender may hire or pay someone else to help
collect this Agreement if Borrower does not pay. Borrower also will pay Lender
that amount. This includes, subject to any limits under applicable law, Lender's
attorneys' fees and Lender's legal expenses whether or not there is a lawsuit,
including attorneys' fees and legal expenses for bankruptcy proceedings
(including efforts to modify or vacate any automatic stay or injunction),
appeals, and any anticipated post-judgement collection services. If not
prohibited by applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO
LENDER AND ACCEPTED BY LENDER IN THE STATE OF COLORADO. IF THERE IS A LAWSUIT,
BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE
COURTS OF BOULDER COUNTY, THE STATE OF COLORADO. LENDER AND BORROWER HEREBY
WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM
BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security 
interest in, and hereby assigns, conveys, delivers, pledges, and transfers
to Lender all Borrower's right, title and interest in and to, Borrower's
accounts with Lender (whether checking, savings, or some other account),
including without limitation all accounts held jointly with someone else and all
accounts Borrower may open in the future, excluding however all IRA, Keogh, and
trust accounts.  Borrower authorizes Lender, to the extent permitted by
applicable law, to charge or setoff all sums owing on this Agreement against any
and all such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

MISCELLANEOUS PROVISIONS. Lender may delay or forgo enforcing any of its rights
or remedies under this Agreement without losing them. Borrower and any other
person who signs, guarantees or endorses this Agreement, to the extent allowed
by law, waive presentment, demand for payment, protest and notice of dishonor.
Upon any change in the terms of this Agreement, and unless otherwise expressly
stated in writing, no party who signs this Agreement, whether as maker,
guarantor, accommodation maker or endorser, shall be released from liability.
All such parties agree that Lender may renew or extend (repeatedly and for any
length of time) this loan, or release any party or guarantor or collateral; or
impair, fail to realize upon or perfect Lender's security interest in the
collateral; and take any other action deemed necessary by Lender without the
consent of or notice to anyone. All such parties also agree that Lender may
modify this loan without the consent of or notice to anyone other than the
party with whom the modification is made.

PRIOR TO SIGNING THIS AGREEMENT, BORROWER READ AND UNDERSTOOD ALL THE

PRINCIPAL AMOUNT: $633,000.00                                                        DATE OF AGREEMENT: OCTOBER 15, 1995
</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $1,500,000.00.

DESCRIPTION OF CHANGE IN TERMS: THE MATURITY DATE WILL NOW BE NOVEMBER 15,
1995.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("BORROWER") PROMISES TO PAY TO BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF SIX
HUNDRED THIRTY THREE THOUSAND & 00/100 DOLLARS ($633,000.00) OR SO MUCH AS MAY
BE OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL
BALANCE OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH
ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING
PRINCIPAL PLUS ALL ACCRUED UNPAID INTEREST ON NOVEMBER 15, 1995. Interest on
this Agreement is computed on a 365/360 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate
in writing. Unless otherwise agreed or required by applicable law, payments
will be applied first to accrued unpaid interest, then to principal, and any
remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS, AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL  BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 2.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 11.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be 
more than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum 
interest charge, Borrower may pay without penalty all or a portion of the 
amount owed earlier than it is due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due.  (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or perform when
due any other term, obligation, covenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
or loan Borrower has with Lender.   (c) Borrower defaults under any loan, 
extension of credit, security agreement, purchase or sales agreement, or any 
other agreement, in favor of any other creditor or person that may materially 
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired. 
                                        
LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to Prime Rate + 5.0% per annum, and
(b) add any unpaid accrued interest to principal and such sum will bear
interest therefrom until paid at the rate provided in this Agreement 
(including any increased rate). The interest rate will not exceed the maximum 
rate permitted by applicable law.  Lender may hire or pay someone else to help 
collect this Agreement if Borrower does not pay. Borrower also will pay Lender 
that amount. This includes, subject to any limits under applicable law, 
Lender's attorneys' fees and Lender's legal expenses whether or not there is a 
lawsuit, including attorneys' fees and legal expenses for bankruptcy 
proceedings (including efforts to modify or vacate any automatic stay or 
injunction), appeals, and any anticipated post-judgement collection services. 
If not prohibited by applicable law, Borrower also will pay any court costs, 
in addition to all other sums provided by law. THIS AGREEMENT HAS BEEN 
DELIVERED TO LENDER AND ACCEPTED BY LENDER IN THE STATE OF COLORADO.  IF THERE 
IS A LAWSUIT, BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE 
JURISDICTION OF THE COURTS OF BOULDER COUNTY, THE STATE OF COLORADO. LENDER 
AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, 
PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE 
OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH 
THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts.  Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

                             EFFECTIVE May 14, 1995

It is agreed that pursuant to the provisions of Ex-Im Bank loans and guarantees

November 13, 1994 country limitation schedule and any amendments thereto.

Insureds, and brokers will be notified of any amendments to this country
limitation schedule in writing. A full revision is generally completed every
six months to one year. All special conditions should be reviewed as many have
been amended.

                               GENERAL CONDITIONS

Exceptions to any condition or limitation contained herein must be obtained in
writing from Ex-Im Bank.

Ex-Im Bank reserves the right to set additional conditions for any particular
buyer or issuing bank including the right to set a different percentage of
coverage. Ex-Im Bank also reserves the right to reject any particular
application.

           Bank is developing arrangements with other Chinese financial
           institutions. Ex-Im Bank will consider transactions with other

           insurance, Ex-Im Bank will require an indication of host government
           support for the application. Contact Ex-Im Bank for more detailed
           information on specific markets.

 #5.       Ex-Im Bank cover/support for private sector transactions is limited

                           INFORMATION SUPPLEMENT ON
                         MEDIUM- AND LONG-TERM PROGRAMS

"Open for Cover" versus "Off-Cover". The attached Country Limitation Schedule
indicates where Ex-Im Bank is "open for cover" and where Ex-Im Bank is
"off-cover". The Schedule is organized along three dimensions: the country
where the risk lies, sector (public sector or private sector), and term of
total exposure (including both disbursement period and repayment term. Ex-Im
Bank defines "public sector" as including those obligors or guarantors which
are at least 50% owned, directly or indirectly, by the government. Where the
CLS Presents an X Mark, Ex-IM Bank is "off-cover", and is therefore not willing
to consider approval of routine transactions. These "off-cover" determinations
are due to economic and/or political risks associated with the country.

WHERE EX-IM BANK IS OPEN FOR COVER. The "open for cover" designation refers to
the possibility, rather than the certainty, of Ex-Im Bank support in particular
cases. Proposed obligors, guarantors, and transaction structures under medium-
and long-term programs are all subject to case-by-case Bank approval. Approval
depends on the case-by-case application of Bank policies, particularly the
Bank's determination of reasonable assurance of repayment. The following
paragraphs provide very general guidance to the application of policies in
markets where Ex-Im Bank is on-cover.

    o      IDENTIFICATION OF OBLIGOR OR GUARANTOR. Ex-Im Bank will approve a
           final commitment, a preliminary commitment (PC), or a medium-term
           insurance policy or commitment (MTIP or MTIC), only if a specific
           obligor or guarantor has been identified, Ex-Im Bank may approve an
           indicative letter of interest (LI) for a proposed transaction,
           subject to the condition that an obligor or guarantor is identified
           at the time the LI is converted to a final commitment, PC, MTIP, or
           MTIC; an Ex-Im Bank can accept the credit risk of the proposed
           obligor or guarantor.

    o      INFORMATION REQUIREMENTS REGARDING OBLIGORS OR GUARANTORS. Ex-Im
           Bank requires that obligors or guarantors offer "reasonable
           assurance of repayment." To process applications for final
           commitments, PCs, MTIPs, and MTICs, Ex-Im Bank will first require
           information on proposed obligors and guarantors. Such information
           includes financial statements and credit references. Engineering
           data is required for long-term transactions.  Generally, Ex-Im Bank
           will require more detailed information regarding obligors or
           guarantors when processing relatively large transactions, or
           transactions with obligors or guarantors with which Ex-Im Bank has
           had no favorable direct credit experience. Ex-Im Bank's application
           form and program literature specify the Bank's standard information
           requirements.

    o      SOVEREIGN GUARANTEES FOR PUBLIC SECTOR BUYERS OR OBLIGORS. For most 
           cases involving proposed public sector buyers or obligors, Ex-Im 
           Bank will routinely require a sovereign guarantee. This is 
           particularly true when the public sector obligor is dependent on 
           government budget support or otherwise lacks financial and 
           operating independence.

    o      PRIOR-HOST GOVERNMENT REVIEW OF SOVEREIGN CASES IN SOME COUNTRIES.
           In some countries, Ex-Im Bank requires prior review of proposed
           public sector cases by government authorities responsible for
           providing the sovereign guarantee, before Ex-Im Bank will begin
           processing action.
<PAGE>   40
Page 10 of 11

    o      TEMPORARY SUSPENSION OF COVER. In countries where the CLS indicated
           that Ex-Im Bank is "open for cover", Ex-Im Bank may, under certain
           circumstances, temporally suspend cover. This is most likely to be
           the case for public sector obligors and guarantors only, but may
           involve all obligors and guarantors. In such an event, Ex-Im Bank
           will advise applicants as quickly as possible.

    o      LARGE TRANSACTIONS IN SMALLER MARKETS. Relatively large transactions
           in smaller economies, even when sovereign guaranteed, will be
           subject to special Ex-Im Bank review. Ex-Im Bank will review the
           potential macroeconomic impacts of the transaction, in terms of
           higher debt burden and improved debt repayment capacity.

    o      PRIVATE COMPANIES. Ex-Im Bank will accept the direct credit risks of
           private buyers, if available information suggests that these buyers
           offer a "reasonable assurance of repayment." For closely-held
           companies, Ex-Im Bank may require financial information from owners.
           For holding companies, Ex-Im Bank may require financial information
           on operating components, and may require their counter-guarantee.

    o      COMMERCIAL BANK GUARANTEES. Ex-Im Bank may require the guarantees of
           acceptable commercial banks in the event that information available
           to Ex-Im Bank on proposed private buyers suggests that these buyers
           by themselves do not offer a "reasonable assurance of repayment."

    o      LIMITED RECOURSE PROJECTS. Ex-Im Bank will consider limited-recourse
           project finance structures (those without full recourse to an
           acceptable, established obligor or guarantor), but only after a
           comprehensive review of project features. These features shall
           include the financial commitment of the project's equity
           shareholders over the life of the proposed Ex-Im Bank commitment;
           the experience and capacity of project participants, including 
           suppliers and offtakers; project cash flow coverage of foreign 
           currency debt service; and security structures, including hard 
           currency external payments arrangements. Ex-Im Bank will review 
           only well- developed proposals, and will require project sponsors 
           to fund review of project proposals by consultants retained by the
           Bank. Significant changes to proposed structures may be required.

    o      POLITICAL-ONLY COVER. Ex-Im Bank's standard guarantee and insurance
           cover is "comprehensive", under which Ex-Im Bank will pay claims
           resulting from both commercial and political perils. Ex-Im Bank also
           offers a narrower form of coverage, under "political-only" cover.
           Ex-Im Bank's guarantee agreements and insurance policies describe in
           detail and or define the specific risks which are subject to this
           form of coverage.

           THE FOLLOWING IS INTENDED AS A SUMMARY: For long-term transactions,
           Ex-Im Bank covers default arising from three "core" perils: transfer
           risk; expropriation, and political violence. Transfer risk involves
           borrowers' inability to acquire foreign exchange through legal
           foreign exchange markets. Expropriation involves the government's
           confiscation of assets or ownership, or arbitrary or discriminatory
           intervention in business operations. Political violence involves
           war, revolution, insurrection, and other such acts. Under
           medium-term insurance policies, Ex-Im Bank also covers defaults
           arising from other defined risks.
<PAGE>   41
                                                                   Page 11 of 11

           Suppliers and/or lenders choosing political-only cover must be
           prepared to assume broad commercial risks associated with the
           borrower's capacity. Ex-Im Bank's political-only cover does not
           cover defaults arising from the borrower's capacity to withstand
           domestic or international commercial market disruptions, or currency
           devaluation or depreciation. If suppliers and/or lenders are unable
           to assume these and other commercial risks, the Ex-Im Bank
           comprehensive cover would be a more appropriate form of coverage.

           Political-only cover is offered only for private buyers or
           borrowers, those which are not subject to the administration of
           government authorities, and for which it is possible to distinguish
           between commercial perils and political-risk perils. Political-only
           cover is the only form of coverage available from Ex-Im Bank for
           borrowers which are effectively controlled by suppliers and/or
           lenders participating in transactions.  Political-only cover is
           available only in those countries where Ex-Im Bank is "open for
           cover" for private sector risk.

WHERE EX-IM BANK IS OFF COVER FOR COUNTRY CREDIT REASONS. Ex-Im Bank will not
consider routine transactions in countries and sectors (public or private)
where the country limitation schedule indicates that the Bank is off-cover
(where there is an X). However, four special categories of transactions may be
eligible for Ex-Im Bank support, under restrictive conditions, subject to
additional special review:

    o      BORROWERS ON INTERNATIONAL CAPITAL MARKETS. Individual borrowers
           (either public sector or private sector) with a strong record of
           independent access to private international capital markets, absent
           external (including sovereign) guarantees. The fee grade assigned,
           and the extent of Ex-Im Bank support, will take into account
           information related to the borrower's capital market financings and
           ratings. For Ex-Im Bank to consider such borrowers, information on
           the borrower's internationally-traded securities, including their
           credit ratings, face values and coupons, recent market values, and
           recent yields, must accompany the application.

    o      INSULATED PROJECT FINANCE STRUCTURES. Ex-Im Bank's approval in
           "off-cover" markets/sectors of limited-recourse structures depends
           on the establishment of structures which do not require the
           financial or operating commitments of host government agencies and
           which are effectively insulated from government involvement.
           Furthermore, these structures must involve the channeling of project
           foreign exchange earnings through offshore payments and escrow
           mechanisms. In some country environments, the only acceptable
           limited-recourse structures may be "enclave" projects which are
           almost completely insulated from the broader country environment.
           The fee grade assigned, and the extent of Ex-Im Bank support, will
           take into account project structure and other conditions.

    o      SECURED LONG-RANGE AIRCRAFT LEASES. Ex-Im Bank approval of
           asset-secured long-range aircraft lease transactions requires that
           the airline's country of registry become a signatory to
           international conventions protecting aircraft property rights. Ex-Im
           Bank approval for aircraft transactions in off-cover markets is more
           likely for privately-owned airlines with established operating
           records. Depending on the nature of transaction participants and
           structures, Ex-Im Bank may also require offshore payments and escrow
           mechanisms, or may provide a reduced percentage of cover. Aircraft
           transactions are subject to special fees and covenants.

    o      ACCEPTABLE BORROWER OUTSIDE THE COUNTRY. Support may be available if
           an acceptable financial institution (e.g. commercial or
           multinational bank) outside of the country acts as the obligor.

Because these transactions are subject to individual special review, Ex-Im Bank
will not approve letters of interest (LIs) for them. It should be noted that
these exceptions do not apply in countries where Ex-Im Bank is legally
prohibited form operating.

========================================================================================================================
PRINCIPAL AMOUNT: $500,000.00                                                     DATE OF AGREEMENT: NOVEMBER 15, 1995
</TABLE>

DESCRIPTION OF EXISTING INDEBTEDNESS. A PROMISSORY NOTE DATED SEPTEMBER 20,
1994 IN THE ORIGINAL PRINCIPAL AMOUNT OF $1,500,000.00.

DESCRIPTION OF CHANGE IN TERMS: THE MATURITY DATE WILL NOW BE MARCH 30, 1996.

PROMISE TO PAY. SCIENTIFIC SOFTWARE - INTERCOMP, INC., A COLORADO CORPORATION
("BORROWER") PROMISES TO PAY TO BANK ONE, COLORADO, N.A. ("LENDER"), OR ORDER,
IN LAWFUL MONEY OF THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF FIVE
HUNDRED THOUSAND & 00/100 DOLLARS ($500,000.00) OR SO MUCH AS MAY BE
OUTSTANDING, TOGETHER WITH INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL BALANCE
OF EACH ADVANCE. INTEREST SHALL BE CALCULATED FROM THE DATE OF EACH ADVANCE
UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING PRINCIPAL
PLUS ALL ACCRUED UNPAID INTEREST ON MARCH 30, 1996. IN ADDITION, BORROWER WILL
PAY REGULAR MONTHLY PAYMENTS OF ACCRUED UNPAID INTEREST BEGINNING NOVEMBER 30,
1995, AND ALL SUBSEQUENT INTEREST PAYMENTS ARE DUE ON THE SAME DAY OF EACH MONTH
AFTER THAT. Interest on this Agreement is computed on a 365/360 simple interest
basis; that is, by applying the ratio of the annual interest rate over a year of
360 days, multiplied by the outstanding principal balance, multiplied by the
actual number of days the principal balance is outstanding. Borrower will pay
Lender at Lender's address shown above or at such other place as Lender may
designate in writing. Unless otherwise agreed or required by applicable law,
payments will be applied first to accrued unpaid interest, then to principal,
and any remaining amount to any unpaid collection costs and late charges.

VARIABLE INTEREST RATE. The interest rate on this Agreement is subject to
change from time to time based on changes in an index which is the LENDER'S
PRIME RATE (the "Index"). PRIME RATE IS THE LENDER'S BASE LENDING RATE AS
ANNOUNCED BY THE LENDER FROM TIME TO TIME AT ITS SOLE DISCRETION. AT ANY GIVEN
TIME, THE LENDER MAY MAKE LOANS AT, ABOVE, OR BELOW ITS PRIME RATE. Lender will
tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each DAY.  THE INDEX
CURRENTLY IS 8.750% PER ANNUM. THE INTEREST RATE TO BE APPLIED TO THE UNPAID
PRINCIPAL  BALANCE OF THIS AGREEMENT WILL BE AT A RATE OF 2.500 PERCENTAGE
POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 11.250% PER ANNUM.
NOTICE: Under no circumstances will the interest rate on this Agreement be 
more than the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. In any event, even upon full prepayment of
this Agreement, Borrower understands that Lender is entitled to a MINIMUM
INTEREST CHARGE OF $25.00. Other than Borrower's obligation to pay any minimum 
interest charge, Borrower may pay without penalty all or a portion of the 
amount owed earlier than it is due. Early payments will not, unless agreed to 
by Lender in writing, relieve Borrower of Borrower's obligation to continue to 
make payments of accrued unpaid interest. Rather, they will reduce the 
principal balance due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this
Agreement or any agreement related to this Agreement, or in any other agreement
of loan Borrower has with Lender. (c) Borrower defaults under any loan,
extension of credit, security agreement, purchase or sales agreement, or any
other agreement, in favor of any other creditor or person that may materially
affect any of Borrower's property or Borrower's ability to repay this Note or
perform Borrower's obligations under this Note or any of the Related Documents.
(d) Any representation or statement made or furnished to Lender by Borrower or
on Borrower's behalf is false or misleading in any material respect either now
or at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor tries
to take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with Lender.
(g) Any of the events described in this default section occurs with respect to
any guarantor of this Agreement. (h) A material adverse change occurs in
Borrower's financial condition, or Lender believes the prospect of payment or
performance of the indebtedness is impaired.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Agreement and all accrued unpaid interest immediately due,
without notice, and then Borrower will pay that amount. Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following: (a) increase
the variable interest rate on this Agreement to 5% over the Index per annum, and
(b) add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Agreement (including any
increased rate). The interest rate will not exceed the maximum rate permitted by
applicable law. Lender may hire or pay someone else to help collect this
Agreement if Borrower does not pay. Borrower also will pay Lender that amount.
This includes, subject to any limits under applicable law, Lender's attorneys'
fees and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including efforts
to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgement collection services. If not prohibited by applicable
law, Borrower also will pay any court costs, in addition to all other sums
provided by law. THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED BY
LENDER IN THE STATE OF COLORADO.  IF THERE IS A LAWSUIT, BORROWER AGREES UPON
LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF BOULDER COUNTY,
THE STATE OF COLORADO. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY
TRIAL IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR
BORROWER AGAINST THE OTHER. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF COLORADO.

RIGHT OF SETOFF. Borrower grants to Lender a contractual possessory security
interest in, and hereby assigns, conveys, delivers, pledges, and transfers to
Lender all Borrower's right, title and interest in and to, Borrower's accounts
with Lender (whether checking, savings, or some other account), including
without limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA, Keogh, and trust
accounts. Borrower authorizes Lender, to the extent permitted by applicable
law, to charge or setoff all sums owing on this Agreement against any and all
such accounts.

LINE OF CREDIT. This Agreement evidences a revolving line of credit. Advances
under this Agreement, as well as directions for payment from Borrower's
accounts, may be requested orally or in writing by Borrower or by an authorized
person. Lender may, but need not, require that all oral requests be confirmed
in writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Agreement at any time may be evidenced by endorsements on this Agreement or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Agreement if: (a) Borrower or
any guarantor is in default under the terms of this Agreement or any agreement
that Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Agreement; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Agreement or any other loan with Lender; or (d) Borrower has applied funds
provided pursuant to this Agreement for purposes other than those authorized by
Lender.

CONTINUING VALIDITY. Except as expressly changed by this Agreement, the terms
of the original obligation or obligations, including all agreements evidenced
or securing the obligation(s), remain unchanged and in full force and effect.
Consent by Lender to this Agreement does not waive Lender's right to strict
performance of the obligation(s) as changed, nor obligate Lender to make any
future change in terms. Nothing in this Agreement will constitute a
satisfaction of the obligation(s). It is the intention of Lender to retain as
liable parties all makers and endorsers of the original obligation(s),
including accommodation parties, unless a party is expressly released by Lender
in writing. Any maker or endorser, including accommodation makers, will not be
released by virtue of this Agreement. If any person who signed the original
obligation does not sign this Agreement below, then all persons signing below
acknowledge that this Agreement is given conditionally, based on the
representation to Lender that the non-signing party consents to the changes and
provisions of this Agreement or otherwise will not be released by it. This
waiver applies not only to any initial extension, modification or release, but
also to all such subsequent actions.

or remedies under this Agreement without losing them. Borrower and any other
person who signs, guarantees or endorses this Agreement, to the extent allowed

Upon any change in the terms of this Agreement, and unless otherwise expressly
stated in writing, no party who signs this Agreement, whether as maker,

length of time) this loan, or release any party or guarantor or collateral; or

year.  In the opinion of management, no events have occurred that would require
any change to the financial statements covered by the report.

without explanation.

                        CONSENT OF INDEPENDENT AUDITORS

This report is a copy of a previously issued Ernst & Young LLP audit report.
Ernst & Young LLP resigned as Company auditors on August 5, 1993, has not
withdrawn its opinion for 1992, but has declined to reissue this report.  The
1992 financial statements included in this report are the same as the audited
financial statements previously filed in the Form 10-K for that year. In the
opinion of management, no events have occurred that would require any change to
the financial statements covered by the report.

The Company's management understands that Ernst & Young LLP has declined to
reissue its report in light of the problems relating to the value added
reseller (VAR) contracts because the reissuance of said report would require an
amount of time and expense so as to make reissuance impracticable.
