The following discussion of our historical results of operations and our
liquidity and capital resources should be read in conjunction with the condensed
consolidated financial statements and related notes that appear elsewhere in
this report and our most recent annual report for the year ended April 30, 2022,
as filed on Form 10-K.

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains certain "forward-looking
statements," which include information relating to future events, future
financial performance, strategies, expectations, competitive environment,
regulation, and availability of resources. These forward-looking statements
include, without limitation, statements regarding: proposed new programs;
expectations that regulatory developments or other matters will not have a
material adverse effect on our financial position, results of operations, or
liquidity; statements concerning projections, predictions, expectations,
estimates, or forecasts as to our business, financial and operational results,
and future economic performance; and statements of management's goals and
objectives and other similar expressions concerning matters that are not
historical facts. Words such as "may," "should," "could," "would," "predicts,"
"potential," "continue," "expects," "anticipates," "future," "intends," "plans,"
"believes," "estimates" and similar expressions, as well as statements in future
tense, identify forward-looking statements.

Forward-looking statements should not be read as a guarantee of future
performance or results and will not necessarily be accurate indications of the
times at, or by, which such performance or results will be achieved.
Forward-looking statements are based on information available at the time those
statements are made or management's good faith belief as of that time with
respect to future events, and are subject to risks and uncertainties that could
cause actual performance or results to differ materially from those expressed in
or suggested by the forward-looking statements.

Forward-looking statements speak only as of the date the statements are made.
Factors that could cause actual results to differ from those discussed in the
forward-looking statements include, but are not limited to, those described in
"Risk Factors" in Part I, Item 1A of our Annual Report on Form 10-K for the
fiscal year ended April 30, 2022, as updated in our subsequent reports filed
with the SEC, including any updates found in Part II, Item 1A of this or other
reports on Form 10-Q, if any. You should not put undue reliance on any
forward-looking statements. We assume no obligation to update forward-looking
statements to reflect actual results, changes in assumptions, or changes in
other factors affecting forward-looking information, except to the extent
required by applicable securities laws. If we do update one or more
forward-looking statements, no inference should be drawn that we will make
additional updates with respect to those or other forward-looking statements.

Overview and Recent Developments
We are a technology-enabled research organization engaged in creating
transformative technology solutions to be utilized in drug discovery and
development. Our research center consists of a comprehensive set of
computational and experimental research platforms. Our pharmacology, biomarker,
and data platforms are designed to facilitate drug discovery and development at
lower costs and increased speeds. We perform studies which we believe may
predict the efficacy of experimental oncology drugs or approved drugs as
stand-alone therapies or in combination with other drugs and can stimulate the
results of human clinical trials. These studies include in vivo studies that
rely on implanting multiple tumors from our TumorBank in mice and testing the
therapy of interest on these tumors. Studies may also include bioinformatics
analysis that reveal the differences in the genetic signatures of the tumors
that responded to a therapy as compared to the tumors that did not respond.
Additionally, we provide computational or experimental support to identify novel
therapeutic targets, select appropriate patient populations for clinical
evaluation, identify potential therapeutic combination strategies, and develop
biomarker hypothesis of sensitivity or resistance. These studies include the use
of our in vivo, ex vivo, analytical and computational platforms.

We are engaged in the development and sale of advanced technology solutions and
products to personalize the development and use of oncology drugs through our
Translational Oncology Solutions ("TOS"). This technology ranges from
computational-based discovery platforms, unique oncology software solutions, and
innovative and proprietary experimental tools such as in vivo, ex vivo and
biomarker platforms. Utilizing our TumorGraft Technology Platform ("The
Platform"), a comprehensive
                                       18
--------------------------------------------------------------------------------

Bank of unique, well characterized models, we provide select services to
pharmaceutical and biotechnology companies seeking personalized approaches to
drug development. By performing studies to predict the efficacy of oncology
drugs, our Platform facilitates drug discovery with lower costs and increased
speed of drug development as well as increased adoption of existing drugs.

As part of our growth strategy, we launched Lumin Bioinformatics ("Lumin"), an
oncology data-driven software program. Our Lumin software contains comprehensive
information derived from our research services and clinical studies. Lumin
leverages our large Datacenter coupled with analytics and artificial
intelligence to provide a robust tool for computational cancer research. It is
the combination of the Datacenter and the analytics that create a unique
foundation for Lumin. Insights developed using Lumin can provide the basis for
biomarker hypotheses, reveal potential mechanisms of therapeutic resistance, and
guide the direction of additional preclinical evaluations.

Our drug discovery and development business leverages the computational and
experimental capabilities within our platforms. Our discovery strategy utilizes
our rich and unique Datacenter, coupled with artificial intelligence and other
advanced computational analytics, to identify novel therapeutic targets. We then
employ the use of our proprietary experimental platforms to rapidly validate
these targets for further drug development efforts.

We have a rich pipeline of targets at various stages of discovery and
validation, with a select group that has progressed to therapeutic development.
Our commercial strategy for the validated targets and therapeutics established
from this business is wide-ranging and still being developed. It will depend on
many factors, and will be specific for each target or therapeutic area
identified. Any expenses associated with this part of our business are research
and development and are expensed as incurred.

We regularly evaluate strategic options to create additional value from our drug discovery business, which may include, but are not limited to, potential spin-out transactions or capital raises.

Liquidity and Capital Resources



Our liquidity needs have typically arisen from the funding of our research and
development programs and the launch of new products, working capital
requirements, and other strategic initiatives. Recently, we have met these cash
requirements through cash, working capital management, and sales of products and
services. In the past, we have also received proceeds from certain private
placements and public offerings of our securities. For the six months ended
October 31, 2022, the Company had a net loss of approximately $335,000 and cash
provided by operations of $3.1 million. As of October 31, 2022, the Company had
an accumulated deficit of approximately $72.3 million, working capital of $1.9
million, and cash of $10.8 million. We believe that our cash on hand, together
with expected positive cash flows from operations for fiscal year 2023, are
adequate to fund operations through at least 12 months from the filing of this
10-Q. However, should our revenue expectations not materialize, we believe we
have cost reduction strategies that could be implemented without disrupting the
business or restructuring the Company. Should the Company be required to raise
additional capital, there can be no assurance that management would be
successful in raising such capital on terms acceptable to us, if at all.

Oncology Services Revenue

Oncology services revenue, which is primarily derived from pharmacology studies,
was $14.3 million and $11.8 million for the three months ended October 31, 2022
and 2021, respectively, an increase of $2.5 million or 21.2%. Oncology services
revenue was $28.0 million and $23.0 million for the six months ended October 31,
2022 and 2021, respectively, an increase of $5.0 million or 21.6%. The increase
in revenue was primarily due to continued demand for our services and platform
expansion leading to larger in-vivo and ex-vivo pharmacology studies.

Cost of Oncology Services



Cost of oncology services for the three months ended October 31, 2022 and 2021
were $7.4 million and $5.6 million, respectively, an increase of $1.8 million or
32.7%.  Cost of oncology services for the six months ended October 31, 2022 and
2021 were $14.5 million and $11.0 million, respectively, an increase of $3.5
million or 31.7%. The increase in cost of oncology services was primarily from
compensation, mice and supply expenses for pharmacology studies and compensation
expense for our SaaS platform. For the three months ended October 31, 2022 and
2021, total gross margins were 47.9% and 52.4%, respectively. For the six months
ended October 31, 2022 and 2021, total gross margins were 48.3% and 52.2%,
respectively. For the three months ended October 31, 2022 and 2021, gross
margins for pharmacology services were 50.5% and 53.1%, respectively. For the
six months ended October 31, 2022 and 2021, gross margins for pharmacology
services were 51.1% and 52.8%, respectively. The lower pharmacology margins
resulted from an increase in up-front study related expenses in advance of the
revenue recognition. Additionally, Lumin related depreciation and amortization
expense during the three and six months ended October 31, 2022 was higher
compared to the three and six months ended October 31, 2021, contributing to the
total margin decline.

Research and Development



Research and development expenses for the three months ended October 31, 2022
and 2021 were $2.6 million and $2.3 million, respectively, an increase of
approximately $305,000 or 13.3%. Research and development expenses for the six
months ended October 31, 2022 and 2021 were $5.5 million and $4.6 million,
respectively, an increase of approximately $888,000 or 19.3%. The increase for
the three and six-month periods was mainly due to compensation and lab supply
expense related to the investment in our therapeutic drug discovery platform.

Sales and Marketing



Sales and marketing expenses for the three months ended October 31, 2022 and
2021 were $1.7 million and $1.6 million, respectively, an increase of $60,000,
or 3.7%. Sales and marketing expenses for the six months ended October 31, 2022
and 2021 were $3.4 million and $3.2 million, respectively, an increase of
178,000, or 5.5%. The increase for both periods was mainly due to compensation
expense.

General and Administrative

General and administrative expenses for the three months ended October 31, 2022
and 2021 were $2.5 million and $2.0 million, an increase of $552,000, or 27.9%.
General and administrative expenses for the six months ended October 31, 2022
and 2021 were $4.9 million and $4.1 million, an increase of $800,000, or 19.3%.
General and administrative expenses are primarily comprised of compensation,
insurance, professional fees, IT, and depreciation and amortization expenses.
The increase for the three and six-month period was mainly due to an increase in
compensation and IT related expenses to support the overall infrastructure
growth of the Company. Additionally, bad debt expense increased during the three
and six-month periods ended October 31, 2022, compared to the three and
six-month periods ended October 31, 2021.


Cash Flows

The following discussion relates to the major components of our cash flows:

Cash Flows from Operating Activities



Net cash provided by operating activities was $3.1 million compared to net cash
provided by operations of $1.4 million for the six months ended October 31, 2022
and 2021, respectively. The cash provided by operating activities during the
current period was primarily due to positive operating results excluding
non-cash expenses combined with increases in accounts receivable collections and
accounts payable balances in the ordinary course of business.

Cash Flows from Investing Activities

Net cash used in investing activities was $1.4 million and $1.5 million for the six months ended October 31, 2022 and 2021, respectively. The cash used in investing activities was primarily for the investment in additional lab and computer equipment.

Cash Flows from Financing Activities



Net cash provided by financing activities was $86,000 for the six months ended
October 31, 2022 compared to cash provided by financing activities of $123,000
for the six months ended October 31, 2021. The decrease in cash provided by
financing is related to decrease in stock option exercise activity.

Critical Accounting Estimates and Policies



The preparation of these condensed consolidated financial statements in
conformity with GAAP in the United States requires management to apply
methodologies and make estimates and assumptions that affect the reported
amounts of assets and liabilities and the disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenue and expenses during the reporting period. Significant estimates of the
Company include, among other things, accounts receivable realization, revenue
recognition (replacement of licensed tumors), valuation allowance for deferred
tax assets, valuation of goodwill, and stock compensation and warrant
assumptions. Actual results could differ from those estimates. The Company's
critical accounting policies are summarized in the Company's Annual Report on
Form 10-K, filed with the SEC on July 22, 2022.
                                       21
