                                   (Unaudited)


Note 1: GENERAL
-------

As contemplated by the Securities and Exchange Commission under Item 310(b) of
Regulation S-B, the accompanying financial statements and footnotes have been
condensed and therefore do not contain all disclosures required by generally
accepted accounting principles. The interim financial data are unaudited;
however, in the opinion of Simulations Plus, Inc. (the "Company"), the interim
data include all adjustments, consisting only of normal recurring adjustments,
necessary for a fair statement of the results for the interim periods. Results
for interim periods are not necessarily indicative of those to be expected for
the full year.


Note 2: CASH AND CASH EQUIVALENTS
-------

The Company maintains cash deposits at banks located in California. Deposits at
each bank are insured by the Federal Deposit Insurance Corporation up to
$100,000. The Company has not experienced any losses in such accounts and
believes it is not exposed to any significant credit risk on cash and cash
equivalents.


Note 3: CAPITALIZED COMPUTER SOFTWARE DEVELOPMENT COSTS
-------

Software development costs are capitalized in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 86, "Accounting for the Cost of
Computer Software to be Sold, Leased, or Otherwise Marketed." Capitalization of
software development costs begins upon the establishment of technological
feasibility and is discontinued when the product is available for sale. The
establishment of technological feasibility and the ongoing assessment for
recoverability of capitalized software development costs require considerable
judgement by management with respect to certain external factors including, but
not limited to, technological feasibility, anticipated future gross revenue,
estimated economic life, and changes in software and hardware technologies.
Capitalized software development costs are comprised primarily of salaries and
the purchase of existing software to be used in the Company's software products.

Amortization of capitalized software development costs is provided on a
product-by-product basis on the straight-line method over the estimated economic
life of the products, not exceeding three years. Management periodically
compares estimated net realizable value by product with the amount of software
development costs capitalized for that product to ensure the amount capitalized
is recoverable through revenues. Any excess of development costs to expected net
realizable value is expensed at that time.

GENERAL

BUSINESS
--------

Simulations Plus, Inc. (the "Company" or "Simulations Plus") and its wholly
owned subsidiary, Words+, Inc. ("Words+") produce two types of products: (1)
Simulations Plus, incorporated in 1996, develops and produces modeling and
simulation software for use in pharmaceutical research and for education, and
also provides contract research services to the pharmaceutical industry, and (2)
Words+, founded in 1981, produces computer software and specialized hardware for
use by persons with disabilities, as well as a personal productivity software
program called Abbreviate! for the retail market.

DESCRIPTION OF SIMULATION AND MODELING SOFTWARE
-----------------------------------------------

The development of simulation software involves (1) identifying and
understanding the underlying chemistry, physics, biology, and physiology of the
processes to be simulated, (2) breaking those processes down into the lowest
practical level of individual sub-processes at which the behaviors can be
well-represented mathematically, (3) developing appropriate mathematical
relationships/equations, and (4) converting them into computer subroutines. The
software subroutines representing these individual processes are then integrated
into an overall simulation program, with appropriate coordination between
modules and design of user-friendly interface for inputs and outputs. The
predictions of these programs are then compared to known results in order to
calibrate the simulations and to demonstrate the validity of the models as
useful tools for predicting new results.

The types of simulation software produced by the Company are based on the
equations of chemistry and physics that describe or "model" the behavior of
things in the real world.

                                       7


The Company's GastroPlus(TM) pharmaceutical software simulates the movement,
dissolution/precipitation, chemical/metabolic degradation and absorption of
orally-dosed drug compounds in the gastrointestinal tract of humans and several
laboratory animal species, and with additional inputs, it also simulates the
blood plasma concentration-time history of the drug after it reaches the central
circulation. In 2001, the Company completed the development of, and is now
selling licenses for, an important new extension module for GastroPlus called
the Metabolism and Transporter Module. This module extends the basic simulation
to include enzyme-specific metabolism in both the liver and in intestinal walls,
as well as the effects of transporter proteins that line the intestinal tract
and serve to promote or inhibit drug absorption. In 2002, the Company released a
module called PDPlus(TM), which extends the utility of GastroPlus into
pharmacodynamic modeling, which is the modeling of how a drug affects the body
in terms of both therapeutic effect and adverse side effects. This extends the
market for GastroPlus into Clinical Pharmacology departments in addition to the
use it already enjoys in early discovery and middle development.

A second type of software consists of statistically significant models that
allow prediction of various properties of a chemical compound from just its
molecular structure. These models are not simulations, but instead are formed
from a variety of mathematical functions and relationships, including linear,
nonlinear, and artificial neural network models.

The Company's QMPRPlus(TM) program is the second type of program, and it
provides estimates for the values of several important physicochemical
characteristics of new drug-like molecules with only the structures of the
molecules as input. An optional module for this program predicts permeability in
a special line of cells called MDCK cells. This predictive model was developed
under a funded collaboration with the Affymax Research Institute, at that time a
division of Glaxo Wellcome. During 2002, the Company announced the release of a
powerful "4D Data Mining" module for QMPRPlus, which further extends the utility
of the software through enhanced data visualization and statistical analysis.
Both the MDCK module and the 4D Data Mining module are additional-cost options
to the program.

GastroPlus and QMPRPlus are used by almost every major and a number of smaller
pharmaceutical companies in the U.S., Europe, and Japan. The number of licensee
continues to grow each quarter, and revenues reflect the cumulative effect of
annual license renewals added to new sales.

The Company is now completing the development of one new core product called
QMPRchitect(TM), and is conducting research toward a new additional-cost module
for GastroPlus called PBPKPlus(TM). PBPKPlus will be a module for GastroPlus
that will enable the program to simulate the distribution of drug to various
tissues in the body, such as brain, heart, lungs, pancreas, liver, spleen, and
reproductive organs. The ability to integrate such detail into GastroPlus will
enable researchers to more accurately predict the pharmacokinetic effects (what
happens to the drug when it gets into the body) and the pharmacodynamic effects
(what happens to the body when the drug gets into the body) of new drugs and new

                                       8


dosing regimens. QMPRchitect will allow users to build their own ensemble
artificial neural network models using a highly sophisticated, state-of-the-art
model-building engine that automates the process of finding the most effective
artificial neural network models for a particular database, using the fast
descriptor engine that is part of QMPRPlus to generate the inputs needed to
build the model. In-house testing of QMPRchitect has demonstrated a reduction in
the time required to build very high quality ensemble artificial neural network
(i.e., multiple artificial neural networks whose outputs are averaged) from
60-90 days to as little as a single day. This significant reduction in both
labor and calendar time is expected to revolutionize artificial neural network
model building for structure-to-property predictions. Initial customer
presentations in the U.S., Europe, and Japan have received very enthusiastic
responses.

The Company's award-winning FutureLab(TM) science experiment simulations for
middle school and high school students incorporate the equations of chemistry
and physics for each experiment (optics, electrical circuits, gravity, universal
gravitation, ideal gases, etc.), and allow students to design and conduct their
own experiments in a virtual laboratory environment. Although development of
FutureLab software was discontinued in 1998, low-level sales have continued
through distributors in the U.S., U.K. Australia, and New Zealand.

PRODUCTS
--------

The Company's pharmaceutical software products provide cost-effective solutions
to a number of critical problems in pharmaceutical research, and also serve in
the education of pharmacy and medical students. The Company's pharmaceutical
software products and services to date are focused on the area of pharmaceutical
research known as ADMET (Absorption, Distribution, Metabolism, Elimination, and
Toxicity). The Company released its first pharmaceutical software product,
GastroPlus, in August 1998 and immediately received enthusiastic interest from
researchers in large pharmaceutical companies such as Astra, Glaxo Wellcome,
Pfizer, Pharmacia, The Roche Group, SmithKline Beecham and Zeneca. Since then,
the majority of the world's largest pharmaceutical companies and a steadily
growing number of smaller companies have licensed the software. Some of these
companies have merged to become single companies (e.g., AstraZeneca and
GlaxoSmithKline, Pfizer and Parke-Davis, and soon, Pfizer and Pharmacia), which
give the appearance of fewer customers, but the Company's software is licensed
on an annual basis by geographic location, so no actual loss in sales has
resulted from these mergers. In fact, several of these mergers have resulted in
increased licenses and new geographic locations as divisions who had the
software demonstrate its use to those who did not.

The Optimization Module for GastroPlus was released in November 1998. Two
additional modules, IVIV Correlation and PKPlus(TM) were released in November
2000. The Metabolism and Transporter Module was released in June 2001. The
PDPlus(TM) Module was released during the 4th quarter of last fiscal year.

                                       9


The majority of new sales now include these additional extra-cost modules,
contributing significantly to revenue and earnings growth. GastroPlus has now
become the "gold standard" for simulation of oral drug absorption and
pharmacokinetics, and is in use throughout the industry in the U.S., Japan, and
Europe. Recent sales have included a number of drug delivery companies
(companies that design the actual tablet or capsule for a drug compound that was
developed by another company). Although these companies are considerably smaller
than the pharmaceutical giants, they can realize significant savings in cost and
time through accurate simulation of their drug delivery technologies. The
Company believes this part of the industry, which includes hundreds of
companies, represents major growth potential for GastroPlus.

QMPRPlus (Quantitative Molecular Property Relationships), which can be used as a
companion program to GastroPlus or by itself, takes as inputs the structures of
molecules, and provides estimates for human intestinal permeability,
octanol-water partition coefficient (logP), solubility, diffusivity, blood-brain
barrier penetration, plasma protein binding, and volume of distribution. The
ability to predict these properties prior to running wet lab experiments allows
screening of undesirable compounds much faster and at much lower cost than using
traditional experimental methods.

Most of the estimated parameters generated by QMPRPlus are inputs to GastroPlus.
QMPRPlus thereby extends the utility of GastroPlus into early drug discovery,
during which pharmaceutical companies may not have even made many of the
molecules that have been identified as potential drug candidates. By providing
estimates of physicochemical properties from structure alone, QMPRPlus, by
itself or coupled with GastroPlus, allows researchers to rank order large
numbers of candidate compounds in terms of their potential for human intestinal
absorption. Because pharmaceutical companies are dealing with many millions of
compounds per year, and because the area of ADMET has become a bottleneck, ultra
high throughput screening on the computer ("IN SILICO") is becoming not just a
convenience, but a necessity.

In 1998, the Company executed a License Agreement with Therapeutic Systems
Research Laboratories, Inc. ("TSRL"), Ann Arbor, Michigan, to obtain exclusive
rights to TSRL's technology and database, including data from nearly 60
laboratory experiments to measure the intestinal permeability of drug compounds
in human and/or rat small intestines. As a part of this License Agreement, the
Company is also entitled to ongoing consulting assistance in the development and
further enhancement of the GastroPlus absorption simulation model from TSRL
staff, including Dr. Gordon Amidon. The Company believes that the strategic
advantage of exclusive access to TSRL's database, technology and expertise,
combined with the Company's now well-developed expertise in absorption,
pharmacokinetics, and pharmacodynamics simulation, have resulted in GastroPlus
becoming the de facto standard for oral drug absorption simulation and analysis
within the pharmaceutical industry. The Company is aware that other companies
have developed competitive software; however, based on customer feedback,
management believes there is no significant competition for GastroPlus at this
time. The Company believes that the addition of the Metabolism and Transporter
Module last year, the recently released PDPlus module, and ongoing upgrades of
the core simulation, are advances in the state-of-the-art of oral drug
absorption, pharmacokinetics, and pharmacodynamics analysis. The PBPKPlus module

now in development will further extend the utility of GastroPlus within the
industry. The Company's recognized expertise in oral absorption and
pharmacokinetics is evidenced by the fact that Company staff members have been
invited speakers at over 30 prestigious scientific meetings worldwide in the
past two years, and they continue to be invited to present at a variety of
meetings worldwide. The Company conducts contracted studies for a number of
customers who prefer to have the studies run by the Company's scientists rather
than to acquire the software and train someone to use it.

CONTRACT RESEARCH SERVICES
--------------------------

The Company offers contract research services to the pharmaceutical industry in
the area of gastrointestinal absorption, pharmacokinetics, and related
technologies. The Company continues to perform study contracts for a variety of
pharmaceutical and biotechnology companies. These studies provide an additional
source of revenue for the Company, as well as a means to introduce the Company's
software products to new customers. These studies are also beneficial to the
Company to validate and enhance its products by studying actual data in the
pharmaceutical industry. The company recently completed two study contracts to
analyze drugs that are now in clinical trials. A services contract with a major
pharmaceutical company was recently signed. This company has numerous software
licenses, but desires additional consultation assistance from Company scientists
with certain complex simulation problems.

PHARMACEUTICAL SIMULATIONS SOFTWARE PRODUCT DEVELOPMENT
-------------------------------------------------------

In the area of simulation software for pharmaceutical research, the Company is
pursuing the development of additional modules for GastroPlus and the new
QMPRchitect core program. Although all of our development work cannot be
disclosed for competitive reasons, some of our development efforts include:

(1) PBPKPlus(TM) Module

The PBPKPlus Module for GastroPlus is in early development now. This module will
enable researchers to predict the amount of drug that reaches different body
tissues and organs, enabling more accurate estimation of therapeutic and adverse
effects for different dosing regimens. This is an important new capability
because it opens up the market to researchers who deal in later stage clinical
trials, and who routinely perform PBPK (physiologically based pharmacokinetic)
and PD (pharmacodynamic) analyses. Until now, these analyses were performed
using models that treated absorption and its related processes with simplified
models - often so simplified that calculations were in error. With PBPKPlus
integrated with the sophisticated absorption model in GastroPlus, researchers
will be able to perform more accurate simulations and analyses to better
understand how a drug partitions from the blood into different tissues and
organs. Without the ability to predict these effects, clinical trial costs can
soar when trials must be repeated to determine proper dosing levels. The Company
expects to release this additional-cost module later this year.

                                       11


(2) Multiple Particle Size Dissolution Model

The current dissolution model in GastroPlus uses a single "effective" particle
size. While this model has well represented most tablets, capsules, and
suspensions we have dealt with to date, formulation researchers know that real
dosage forms do not consist of particles that are all one size. Instead, there
is a distribution of particle sizes over some range from smaller than the
average size to larger than the average size. Smaller particles dissolve faster
than larger particles. For some drugs, this results in dissolution behavior that
is not well modeled with a single effective particle size. This new model will
allow formulation researchers to assess the effects of different particle size
distributions on dissolution and absorption.

(3) DDDPlus(TM)

The DDDPlus project was originally begin in 2000, and has proceeded at a slow
pace since in between other higher priority projects. DDDPlus (Dose
Disintegration and Dissolution Plus) will simulate the in vitro disintegration
and dissolution of various forms of capsules and tablets, and will include the
effects of a variety of formulation excipients (additives that are not the
actrive drug, but which give a capsule or tablet desirable roperties such as
longer shelf life, better large-scale processing behavior, better disintegration
and dissolution, etc.). This tool will be a valuable asset for formulation
scientists as they search for optimum formulations that provide desirable
properteis at minimum cost.

(4) QMPRPlus(TM) upgrades

We continue to add new molecular descriptors and new predicted ADMET properties
to QMPRPlus(TM). Last year we completed the development of a new,
additional-cost "4D Data Mining" module.

The number of molecular descriptors has been increased in beta versions of
QMPRPlus by about 25%. These new descriptors include over 60 electrotopological
indices that the Company believes will be valuable in building new models for
pharmacokinetic and metabolism properties, as well as certain other descriptors
that will be described at a later date.

(5) QMPRchitect(TM)

QMPRchitect is well along in development. This new core product will allow
researchers to build their own ensemble artificial neural network models from
their own data using a highly sophisticated, state-of-the-art process for
identifying critical descriptors and training ensemble artificial neural network
models in the most efficient way. Users can have such new models included in the
output of QMPRPlus along with the existing predicted ADME properties. Through
the automation provided in the proprietary software for this module, alpha
versions of the software have demonstrated a reduction in the time to build
powerful ensemble artificial neural network models from many weeks to one or two
days, with higher quality models than were previously possible. The company has

                                       12


received strong indications of interest from customers for this new capability.
The Company expects to release this new core product during the third fiscal
quarter.

DISABILITY PRODUCT DEVELOPMENT
------------------------------

The Company's wholly owned subsidiary, Words+, Inc. has been an industry
technology leader for over 20 years in introducing and improving augmentative
and alternative communication and computer access software and devices for
disabled persons and intends to continue to be at the forefront of the
development of new products. The Company will continue to enhance its major
software products, E Z Keys and Talking Screen, as well as its growing line of
hardware products. The Company announced the release of its new version of E Z
Keys for the new Microsoft XP operating system at the "Technologies for Persons
with Disabilities Conference" in Los Angeles in late March 2002. The Windows XP
version of the Company's Talking Screen software has just been completed at the
time of this writing. The Company will also consider acquisitions of other
products, businesses and companies that are complementary to its existing
augmentative and alternative communication and computer access business lines.

                                    =======================================

NET SALES

Consolidated net sales increased $13,000, or 1.2%, to $1,120,000 in the second
fiscal quarter of 2003 (FY03) from $1,107,000 in the second fiscal quarter of
2002 (FY02). Simulations Plus, Inc.'s sales, from pharmaceutical and educational
software, increased approximately $28,000, or 5.0%. The increase in the
Company's leading pharmaceutical software sales is attributable to a combination
of additional license sales to existing customers, new customers, new modules,
and major upgrades to existing products, which exceeded the a small decline
resulting from non-renewals. For Words+, sales decreased approximately $15,000,
or 2.7% for the quarter. Management attributes the decrease in Words+ sales
primarily to slowing in the economy during this time period.

COST OF SALES

Consolidated cost of sales increased $39,000, or 11.7%, to $372,000 in the
second fiscal quarter of FY03 from $333,000 in the second fiscal quarter of
FY02. The percentage of cost of sales was increased by 3.1%. For Simulations
Plus, the cost of sales increased $11,000, or 14.3%. This increase was due
primarily to increased royalty expense, for which the Company has an agreement
with TSRL, and which increased 25.9% due to increased GastroPlus license sales.
For Words+, the cost of sales increased $28,000, or 10.8%. Management attributes
the percentage increase in cost of sales for Words+ primarily to the fact that
the percentage of sales generated by product items with lower profit margins was
greater than for items with higher profit margins. During this quarter, the
sales through governmental funding increased in proportion to total sales.
Governmental funding requires significant discounts, resulting in higher cost of
sales than for regular sales.

                                       14


GROSS PROFIT

The consolidated gross profit decreased $26,000, or 3.4%, to $748,000 in the
second quarter of FY03 from $774,000 in the second quarter of FY02. Management
attributes this decrease to the increased cost of sales for both pharmaceutical
software sales and Words+ products.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Consolidated selling, general and administrative expenses increased $130,000, or
27.7%, to $599,000 in the second quarter of FY03 from $469,000 in the second
quarter of FY02. For Simulations Plus, selling, general and administrative
expenses increased $146,000, or 96.1% primarily due to increases in commission
paid in accordance with an exclusive alliance agreement, accounting fees, and
investor and public relations fees which began this quarter, increases in
medical insurance, increases in salaries and wages from last year, a transfer of
administrative personnel wages from Words+, and payroll-related expenses such as
401(k) and payroll taxes. Management terminated the public relations firm at the
end of March. Management believes the investor relations firm is performing
acceptably, and continues to employ their services. For Words+, expenses
decreased $16,000, or 5.1%, due to reduced travel expenses, and a transfer of
administrative personnel wages to Simulations plus, with resulting decreases in
payroll related expenses such as 401(k) and payroll taxes. Although there were
some increases in expenses such as health insurance and commission expense,
decreases outweighed increases. A one-time charge for greater year-end bonuses
to employees was also incurred in the second quarter. These bonuses averaged
less than $1500 per employee.

RESEARCH AND DEVELOPMENT

The Company incurred approximately $150,000 of research and development costs
for both companies during the second quarter of FY03. Of this amount, $69,000
was capitalized and $81,000 was expensed in this period. In the second quarter
of FY02, the Company incurred $116,000 of research and development costs, of
which $34,000 was capitalized and $82,000 was expensed. The increase of $34,000,
or 29.3%, in research and development expenditure from the second quarter of
FY02 to the second quarter of FY03 was primarily due to salary increases in the
existing staff members over last year and one-time charges for purchases of
databases of pharmaceutical data to be used in developing additional or improved
predictive models for QMPRPlus.

INTEREST EXPENSE

Interest expense for the second quarter of FY03 decreased by $4,000, or 80.0%,
to $1,000 in the second quarter of FY03 from $5,000 in the second quarter of
FY02. This decrease is attributable primarily to no interest expense on the
Company's revolving line of credit, and the completion of payments on the one of
existing leases.

                                       15


NET INCOME

Consolidated net income for the three months ended February 28, 2003 decreased
by $151,000, or 69.3%, to $67,000 in the second quarter of FY03 compared to
$218,000 in the second quarter of FY02. Management attributes this decrease
primarily to increases in cost of sales and selling, general and administrative
costs, which outweighed increases in net sales, and decrease in interest
expense.

                                    =======================================


NET SALES

Consolidated net sales increased $84,000, or 4.0%, to $2,198,000 for the six
months ended February 28, 2003 compared to $2,114,000 for the six months ended
February 28, 2002. Simulations Plus, Inc.'s sales from pharmaceutical software
and services and educational software increased approximately $145,000, or
15.3%, however, Words+, Inc.'s sales decreased approximately $61,000, or 5.2%
for the six months ended February 28, 2003. Management attributes the increase
in pharmaceutical software sales partially to the Roche order for a new product
package called the "ADME Partners" program, which provides virtually unlimited
licenses for the use of GastroPlus, QMPRPlus and all modules coupled with
product training and consultation. Additionally, average order size has
increased with new orders and with renewals from existing customers due to
additional module licenses. Management attributes the decrease in Words+ sales
primarily to the delay in development of Talking Screen for Windows XP, which
was completed at the end of the second quarter of FY03, as well as overall
slowing in the economy during this time period.

                                       16


COST OF SALES

Consolidated cost of sales decreased $1,000, or 0.1%, to $705,000 for the six
months ended February 28, 2003 from $706,000 for the six months ended February
28, 2002. The percentage of cost of sales decreased by 1.3%. For Simulations
Plus, the cost of sales increased $2,000, or 1.4%. A significant portion of the
cost of sales is the amortization of capitalized software cost, which produced a
2.4% decrease; however, this decrease was offset by a 3.8% increase in royalty
cost. For Words+, the cost of sales decreased $3,000, or 0.5%. Expressed as a
percentage, the change in cost of sales for Words+ between the six months
operations ended February 28, 2003 and February 28, 2002 is an increase of 2.4%.
Management attributes this percentage increase primarily to increased sales of
lower margin items during the first six months compared to the same period of
the previous fiscal year. It is also due to the fact that the sales through
governmental funding increased in proportion to total sales. Governmental
funding requires significant discounts, resulting in a higher cost of sales.

GROSS PROFIT

The consolidated gross profit increased $85,000, or 6.0%, to $1,493,000 for the
six months ended February 28, 2003 from $1,408,000 for the six months ended
February 28, 2002. Management attributes this increase to an increase in
pharmaceutical software and services sales while maintaining the cost of sales
relatively the same. This increase outweighed the slightly decreased gross
profit generated by Words+ products.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Consolidated selling, general and administrative expenses increased $108,000, or
10.9%, to $1,102,000 for the six months ended February 28, 2003 from $994,000
for the six months ended February 28, 2002. For Simulations Plus, selling,
general and administrative expenses increased $151,000, or 46.0% primarily due
to increases in commissions paid in accordance with an exclusive alliance
agreement, new investor relations and public relations services, increases in
health insurance, increases in salary over last year, transfer of administrative
personnel wages from Words+, and payroll-related expenses such as 401(k),
payroll taxes, and increased travel expenses associated with an increase in
customer training. For Words+, expenses decreased $43,000, or 6.5%, due
primarily to transfer of administrative personnel wages to Simulations plus,
payroll related expenses, such as 401(k) and payroll taxes, telephone and auto
expense. Although there are some increases in expenses such as health insurance
and commission expense, the decreases outweighed increases.

RESEARCH AND DEVELOPMENT

The Company incurred approximately $278,000 of research and development costs
for both companies for the six months ended February 28, 2003. Of this amount,
$87,000 was capitalized and $191,000 was expensed in this period. In the same
period of 2002, the Company incurred $226,000 of research and development costs,
of which $50,000 was capitalized and $176,000 was expensed. The increase of

                                       17


$52,000, or 23.0% in research and development expenditure from the six months
operations in the fiscal year 2002 to 2003 was due primarily to an payroll
increases in the existing staff members and one-time charges for purchases of
databases of pharmaceutical data to be used in developing additional or improved
predictive models for QMPRPlus.

INTEREST EXPENSE

Interest expense for the six months ended February 28, 2003 decreased by $7,000,
or 70.0%, to $3,000 from $10,000 for the six months ended February 28, 2002.
This decrease is attributable primarily to an interest rate reduction on the
company's revolving line of credit, and the completion of payments on the one of
existing leases.

NET INCOME

Consolidated net profit for the six months ended February 28, 2003 decreased by
$31,000, or 13.6%, to $197,000 for the six months ended February 28, 2003
compared to $228,000 for the six months ended February 28, 2002. Management
attributes this decrease due to increased selling, general and administrative
expenses and research and development expense, which outweighed the increase in
pharmaceutical software sales and decrease in interest expense. Much of the
increase in SG&A was due to one-time charges for year-end employee bonuses, as
well as new investor relations and public relations expenses. Management
terminated the public relations consultant at the end of March 2003.

LIQUIDITY AND CAPITAL RESOURCES

The Company's principal sources of capital have been cash flows from its
operations and a bank line of credit. The Company has available a $100,000
revolving line of credit from a bank. Interest is payable on a monthly basis at
the bank's prime rate, with a minimum floor of 7.5%, plus 3.5%. At February 28,
2003, the outstanding balance under the revolving line of credit was zero, and
it was $100,000 at February 28, 2002. The revolving line of credit is not
secured by any of the assets of the Company but is personally guaranteed by Mr.
Walter S. Woltosz, the Company's Chief Executive Officer, President and Chairman
of the Board of Directors.

Beginning in August 1998, certain executive officers and managers accepted
reduced salaries on a temporary basis in order to protect the cash assets of the
Company. The unpaid portions of salaries were accrued and was to be paid at such
future time as management deemed the Company's cash flow and cash reserves were
sufficient to make such payments without adverse effects to the Company's
financial position. The amount of such accrued and unpaid salaries due to the
Company's executive officers was approximately $91,000 as of February 28, 2003.
Effective as of March 1, 2002, all officers' salaries have been restored to
their full levels and the remaining balance of $91,000 will be paid as described
above.

The Company believes that existing capital and anticipated funds from operations
will be sufficient to meet its anticipated cash needs for working capital and
capital expenditures for the foreseeable future. Thereafter, if cash generated
from operations is insufficient to satisfy the Company's capital requirements,
the Company may have to sell additional equity or debt securities or obtain
expanded credit facilities. In the event such financing is needed in the future,
there can be no assurance that such financing will be available to the Company,
or, if available, that it will be in amounts and on terms acceptable to the
Company. If cash flows from operations became insufficient to continue
operations at the current level, and if no additional financing was obtained,
then management would restructure the Company in a way to preserve its
pharmaceutical and disability businesses while maintaining expenses within
operating cash flows.

                           PART II. OTHER INFORMATION

Item 1.  Legal Proceedings
         -----------------

         In the normal course of business, the Company may be subject to various
         lawsuits and claims. The Company believes that the final outcomes of
         these matters, either individually or in the aggregate, will not have a
         material effect on the financial statements. The Company is not
         involved in any such litigation at this time.

Item 2.  Changes in Securities
         ---------------------

         None.

Item 3.  Defaults Upon Senior Securities
         -------------------------------

         None.

Item 4.  Submission of Matters to a Vote of Security Holders
         ---------------------------------------------------

         On January 31, 2003, the Registrant held its annual meeting of
         shareholders. The following proposals were submitted to a vote of
         security holders at the meeting.

         (1) Election of directors Walter S. Woltosz, Virginia E. Woltosz, Dr.
             David Z. D'Argenio, and Dr. Richard Weiss

         (2) Ratification of the appointment of Singer, Lewak, Greenbaum &
             Goldstein, LLP as their independent public accountants.

         The preparation and mailing of a proxy was omitted because two persons,
         Walter Woltosz and his wife, Virginia Woltosz, hold a majority of
         voting shares. Instead, a board meeting was held prior to the annual
         meeting at which the two items above were unanimously approved for the
         next fiscal year 2003. There were no other voting issues.

Item 5.  Other Information
         -----------------

         None.
