                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)

                                  MAY 31, 2001



1.       ORGANIZATION AND OPERATIONS

         We are a Michigan corporation that was formed in January 1982. We
develop, manufacture and market the INVOS(R) Cerebral Oximeter, the only
non-invasive patient monitoring system commercially available in the United
States that continuously measures changes in the blood oxygen level in the
brain. The Cerebral Oximeter is based on our proprietary In Vivo Optical
Spectroscopy, or INVOS, technology. INVOS analyzes various characteristics of
human blood and tissue by measuring and analyzing low-intensity visible and near
infrared light transmitted into portions of the body. We are also developing the
CorRestore(TM) patch for use in cardiac repair and reconstruction, including
heart surgeries called surgical anterior ventricular restoration, or SAVR.

2.       FINANCIAL STATEMENT PRESENTATION

         We prepared our unaudited interim financial statements pursuant to the
Securities and Exchange Commission's rules. Accordingly, they do not include all
of the information and footnotes normally included in our annual financial
statements prepared in accordance with generally accepted accounting principles.
We believe, however, that the disclosures are adequate to make the information
presented not misleading.

         The unaudited interim financial statements in this report reflect all
adjustments which are, in our opinion, necessary to a fair statement of the
results for the interim periods presented. All of these adjustments that are
material are of a normal recurring nature. Our operating results for the
six-month period ended May 31, 2001 do not necessarily indicate the results that
you should expect for the year ending November 30, 2001. You should read the
unaudited interim financial statements together with the financial statements
and related footnotes for the year ended November 30, 2000 included in our
Annual Report on Form 10-K for the fiscal year ended November 30, 2000.

         We have incurred an accumulated deficit of $51,684,678 through May 31,
2001. We had working capital of $2,319,770, cash and cash equivalents of
$1,036,141, total current liabilities of $654,383 and shareholders' equity of
$3,668,036 as of May 31, 2001.

         We believe that markets exist for the products we have developed and
are developing; however, whether our products will be successful is uncertain.
You should consider the following factors in evaluating the likelihood of our
success: our limited resources and current financial condition, the problems and
expenses frequently encountered by companies developing a new business, our
ability to raise new funds, our ability to develop, apply and market new
technology, and our industry and competitive environment.

         For further discussion of our financial condition, including recent
sales of securities, our working capital, our liquidity resources, requirements
and plans, and our ability to continue as a going concern, please refer to
"Liquidity and Capital Resources" in "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

</TABLE>

         Intangible Assets consist of patents and trademarks, and license
acquisition costs. Patents and trademarks are recorded at cost and are being
amortized on the straight-line method over 17 years. License acquisition costs
are related to our acquisition of exclusive, worldwide, royalty-bearing licenses
to specified rights relating to the CorRestore(TM) patch and related products
and accessories.

         We entered into a License Agreement as of June 2, 2000 with the
inventors and their company, CorRestore LLC. The license grants us exclusive,
worldwide, royalty-bearing licenses to specified rights relating to the
CorRestore(TM) patch and related products and accessories for SAVR, subject to
the terms and conditions of the license agreement. Pursuant to the license
agreement, CorRestore LLC has agreed to provide various consulting services to
us. We have agreed to pay all of the expenses of such consultation, of clinical
testing of the CorRestore(TM) patch, training doctors in SAVR and training our
personnel and customers in the use of the CorRestore(TM) patch.

         In exchange for the licenses and consulting services, we agreed to the
following compensation for CorRestore LLC and its agent, Wolfe & Company: (1) a
royalty of 10% of our "net sales" of products subject to the licenses, (2)
five-year warrants to purchase up to 400,000 Common Shares at $3.00 a share,
exercisable to purchase 300,000 shares immediately and to purchase an additional
50,000 shares upon our receipt of clearance or approval from the FDA to market
the CorRestore(TM) patch in the United States and another 50,000 shares upon our
receipt of CE certification for the CorRestore(TM) patch, (3) additional
five-year warrants to purchase up to 2,100,000 common shares at $3.00 a share,
to be granted when we receive clearance or approval from the FDA to market the
CorRestore(TM) patch in the United States, exercisable based on our cumulative
net sales of the CorRestore(TM) patch products, and (4) a consulting fee of
$25,000 a year to each of the inventors until we sell 1,000 CorRestore(TM)
patches.

                                   (UNAUDITED)

                                  MAY 31, 2001

         License acquisition costs consist of professional service fees recorded
at cost, our estimate of the fair value of the ten-year vested stock options to
purchase 50,000 common shares at $3.00 a share granted to one of our directors
in connection with negotiating and assisting us in completing the transaction,
and our estimate of the fair value of the 300,000 common share vested portion of
the five-year warrants to purchase up to 400,000 common shares at $3.00 a share
issued in the transaction. We estimated the value of the stock options to
purchase 50,000 common shares using the Black-Scholes valuation model with the
following assumptions: expected volatility (the measure by which the stock price
has fluctuated or is expected to fluctuate during the period) 111.16%, risk-free
interest rate of 7.5%, expected life of 4 years and dividend yield of 0%. We
estimated the value of the warrants to purchase 300,000 common shares using the
Black-Scholes valuation model with the following assumptions: expected
volatility (the measure by which the stock price has fluctuated or is expected
to fluctuate during the period) 111.16%, risk-free interest rate of 7.5%,
expected life of 5 years and dividend yield of 0%.

These costs are being amortized on the straight-line method over 5 years.
Intangible assets consist of:

</TABLE>

         Intangible assets are reviewed periodically for impairment whenever
events or changes in circumstances indicate that the carrying value of the asset
may not be recovered.

         Loss Per Common Share - basic and diluted, is computed using the
weighted average number of common shares outstanding during each period. Common
shares issuable under stock options and warrants have not been included in the
computation of the net loss per Common Share - diluted, because such inclusion
would be antidilutive. As of May 31, 2001 and May 31, 2000, we had outstanding
2,685,515 and 1,944,981, respectively, of warrants and options to purchase
common shares.

         Accounting Pronouncements Effective December 1, 2000, we adopted
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement had no impact on our
financial statements.

         Reclassifications - Certain reclassifications have been made to the
financial statements for 2000 to conform to the 2001 presentation.

5.       COMMITMENTS AND CONTINGENCIES

         We may become subject to products liability claims by patients or
physicians, and may become a defendant in products liability or malpractice
litigation. We have obtained products liability insurance and an umbrella
policy. We might not be able to maintain such insurance or such insurance might
not be sufficient to protect us against products liability.

6.       COMMON STOCK

         On December 4, 2000, we completed the sale of 112,994 common shares to
Kingsbridge, at a price of $1.77 per share, for gross proceeds of $200,000.

         Effective December 4, 2000, we granted 10-year options under the 1991
Stock Option Plan to purchase 14,667 common shares, and we granted 10-year
options under the 1997 Stock Option Plan to purchase 180,333 common shares, to
27 of our key employees (including officers) and one of our consultants at an
exercise price of $1.97 per share (the closing sale price of the common shares
as of the date of grant). Effective March 5, 2001, we granted 10-year options
under the 1997 Stock Option Plan to purchase 322,800 common shares to seven of
our key employees (including officers) at an exercise price of $2.00 per share
(the closing sale price of the common shares as of the date of grant). Stock
Options issued to non-employees are valued at the date of grant using the Black
Scholes valuation model, and are expensed as compensation expense over the
vesting period of the stock option.

         Effective February 22, 2001, we granted to five of our directors, who
are not officers or employees, 10-year options under the 1997 Stock Option Plan
to purchase an aggregate of 10,000 common shares at an exercise price of $2.31
per share (the closing sale price of the common shares as of the date of grant).

         On February 22, 2001, our shareholders approved the issuance of
warrants to purchase 2,100,000 common shares to CorRestore LLC under specified
circumstances pursuant to our CorRestore(TM) license agreement and to issue the
underlying shares upon exercise of those warrants.

         On February 22, 2001, our shareholders approved an amendment to the

                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)

                                  MAY 31, 2001

         Effective March 5, 2001, we de-registered the remaining shares
originally registered for resale by Kingsbridge Capital Limited under the
Private Equity Line Agreement, because we no longer intend to sell any more
shares to Kingsbridge, except upon any exercise of its warrant, and Kingsbridge
is no longer publicly offering for resale the shares subject to the warrant we
granted to them. On April 10, 2001, we mutually agreed with Kingsbridge to
terminate the Private Equity Line Agreement, the related Registration Rights
Agreement, and Kingsbridge's right to the discount on any unsold shares, in
exchange for our payment of $200,000 to Kingsbridge.

         On April 9, 2001, we completed the private placement of 1,325,000
newly-issued common shares at a price of $1.75 per share, for gross proceeds of
$2,318,750. Our estimated net proceeds, after deducting the placement agent's
commission and the estimated expenses of the offering, were approximately
$2,159,000. Brean Murray & Co., Inc. was our exclusive placement agent for the
offering and received for its services (1) $104,362.50 as a placement agent fee,
and (2) warrants to purchase 25,000 common shares at $2.10 per share exercisable
during the four-year period beginning April 9, 2002. A. Brean Murray, one of our
directors, and his wife control Brean Murray & Co., Inc. In addition, the Brean
Murray & Co., Inc. Profit Sharing Plan purchased 32,285 common shares in the
offering, and Robert R. Henry, one of our directors, purchased 100,000 common
shares in the offering.

7.       NOTES PAYABLE - BANK LINE OF CREDIT

         On February 13, 2001, we entered into a Loan and Security Agreement
with Crestmark Bank for a working capital line of credit for up to $750,000,
collateralized by all of our assets. Under the Agreement, Crestmark Bank may,
but is not obligated to, lend us amounts we request from time to time, up to
$750,000, if no default exists. The loans are limited by a borrowing base based
on qualifying accounts receivable and lender reserves. The loan is payable on
demand, and collections of our receivables are directed to Crestmark Bank in
payment of any outstanding balance of the loan.

         The principal amount outstanding bears interest, payable monthly, at
the prime rate (6.75% at July 2, 2001) plus 2% plus a 2.4% service fee, and we
paid a $45,000 commitment fee for the loan. Through May 31, 2001, we have
borrowed $920,050 under the agreement and repaid $920,050 in principal amount
through Crestmark's collection of our receivables and by using some of the
proceeds from our April 9, 2001 offering. As of May 31, 2001, $628,629 was
available for borrowing, at Crestmark's discretion, under the facility. We have
agreed to use the proceeds of the loans solely as working capital. The line of
credit requires us to maintain minimum tangible net worth of $500,000 and a
ratio of total liabilities to tangible net worth not to exceed 3:1. The line of
credit terminates upon Crestmark's demand.

RESULTS OF OPERATIONS

OVERVIEW

         We develop, manufacture and market the INVOS Cerebral Oximeter, the
only non-invasive patient monitoring system commercially available in the United
States that continuously measures changes in the blood oxygen level in the
brain. We are also developing the CorRestore(TM) patch for use in cardiac repair
and reconstruction, including heart surgeries called surgical anterior
ventricular restoration, or SAVR. The model 4100 Cerebral Oximeter was
introduced in October 1997 and we began shipping the model 4100 in the first
quarter of fiscal 1998. During the third quarter of fiscal 1999, we introduced
our new model 5100 Cerebral Oximeter at an international trade show, and began
international shipments of the model 5100 in August 1999. The model 5100
Cerebral Oximeter has the added capability of being able to monitor pediatric
patients. In September 2000, we received clearance from the FDA to market the
model 5100 Cerebral Oximeter in the United States. In June 2000, we entered into
a license agreement for the CorRestore patch, which requires testing and FDA
clearance or approval before we can sell it in the United States. During the
second quarter of fiscal 2001, we submitted our 510(k) application to the FDA
for the CorRestore patch, and are awaiting FDA clearance to market the
CorRestore patch in the United States.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

                                  MAY 31, 2001

         During fiscal 2000 and the first two quarters of fiscal 2001, our
primary activities consisted of sales and marketing of the Cerebral Oximeter and
the related disposable SomaSensor. We had an accumulated deficit of $51,684,678
through May 31, 2001. We believe that our accumulated deficit will continue to
increase for the foreseeable future.

         We derive our revenues from sales of Cerebral Oximeters and SomaSensors
to our distributors and to hospitals in the United States through our direct
sales employees. We recognize revenues when we ship our products to our
distributors or to hospitals. Payment terms are generally net 30 days for United
States sales and net 60 days or longer for international sales. Our primary
expenses, excluding the cost of our products, are selling, general and
administrative and research, development and engineering. During fiscal 1998, we
began a no-cap sales program whereby we ship the Cerebral Oximeter to the
customer at no charge, in exchange for the customer agreeing to purchase at a
premium a minimum monthly quantity of SomaSensors.

THREE MONTHS ENDED MAY 31, 2001 COMPARED TO THREE MONTHS ENDED MAY 31, 2000

         Our net revenues decreased approximately $169,000, or 12%, from
$1,430,066 in the three-month period ended May 31, 2000 to $1,261,513 in the
three-month period ended May 31, 2001. The decrease in net revenues is primarily
attributable to a decrease in international sales of approximately $694,000,
from approximately $769,000 in the second quarter of fiscal 2000 to
approximately $75,000 in the second quarter of fiscal 2001. This decrease is
primarily due to the initial stocking order for model 4100 and model 5100
Cerebral Oximeters and SomaSensors by Tyco Healthcare AG, formerly Nellcor
Puritan Bennett Export Inc., in the second quarter of fiscal 2000, delays in
marketing the Cerebral Oximeter in 39 markets, including Europe, in fiscal 2001,
and reduced purchases by Baxter Limited in Japan in the second quarter of fiscal
2001. We expect international revenues to return to more normal levels by the
fourth quarter of fiscal 2001.

The decrease in net revenues was partially offset by

         -    An increase in United States sales of approximately $525,000, from
              approximately $661,000 in the second quarter of fiscal 2000 to
              approximately $1,186,000 in the second quarter of fiscal 2001.
              This increase is primarily attributable to increased sales of the
              disposable SomaSensor, increased sales of the Cerebral Oximeter,
              and initial purchases of demonstration equipment by independent
              sales representatives.

         -    a 35% increase in the average selling price of Cerebral Oximeters,
              and a 26% increase in the average selling price of SomaSensors,
              primarily as a result of a change in the sales mix between sales
              in the United States and sales to international distributors, a
              change in the United States sales mix between direct sales of the
              Cerebral Oximeter and no-cap placements of the Cerebral Oximeter,
              and the initial stocking purchase by Tyco Healthcare AG, at lower
              per unit prices, in the second quarter of fiscal 2000.

         Approximately 6% of our net revenues in the second quarter of fiscal
2001 were export sales, compared to approximately 54% of our net revenues in the
second quarter of fiscal 2000. Sales of SomaSensors, model 5100 Cerebral
Oximeters, and model 4100 Cerebral Oximeters as a percentage of net revenues
were as follows:

</TABLE>


Two international distributors accounted for approximately 33% and 13%,
respectively, of net revenues for the three months ended May 31, 2000.

         Gross margin as a percentage of net revenues was approximately 67% for
the quarter ended May 31, 2001 and approximately 50% for the quarter ended May
31, 2000. The increase in gross margin as a percentage of net revenues is
primarily attributable to a 35% increase in the average selling price of
Cerebral Oximeters and a 26% increase in the average selling price of
SomaSensors described above.

         Our research, development and engineering expenses increased
approximately $82,000, or 73%, from $112,501 for the three months ended May 31,
2000 to $194,816 for the three months ended May 31, 2001. The increase is
primarily attributable to a $94,000 increase in costs associated with the
development of the CorRestore patch.

     Selling, general and administrative expenses increased approximately
$13,000, or 1%, from $1,491,944 for the three months ended May 31, 2000 to
$1,505,019 for the three months ended May 31, 2001. The increase in selling,
general and administrative expense is primarily attributable to

         -    a $200,000 termination fee related to the Kingsbridge Capital
              Limited Private Equity Line, and

         -    a $54,000 increase in intangible amortization expense related to
              the amortization of license acquisition costs.

These increases were partially offset by

         -    a $144,000 decrease in salaries, wages, commissions and related
              expenses, primarily as a result of a reduction in the number of
              employees, principally sales and marketing, since June 1, 2000
              (from an average of 42 employees for the quarter ended May 31,
              2000 to an average of 33 employees for the quarter ended May 31,
              2001), and

         -    a $130,000 decrease in travel and selling-related expenses
              primarily related to reduced trade show and travel expenses.

                                  MAY 31, 2001

         For the three-month period ended May 31, 2001, we realized a 8%
decrease in our net loss over the same period in fiscal 2000. The decrease is
primarily attributable to

         -    a 17% increase in gross margin percentage, and

         -    a $55,000 decrease in realized losses on sales of securities due
              to a realized loss on the sale of marketable securities in the
              second quarter of fiscal 2000.

The decreased net loss was achieved despite

         -    a 12% decrease in net revenues, and

         -    a 6% increase in operating expenses.

SIX MONTHS ENDED MAY 31, 2001 COMPARED TO SIX MONTHS ENDED MAY 31, 2000

         Our net revenues increased approximately $231,000, or 9%, from
$2,467,680 in the six-month period ended May 31, 2000 to $2,699,006 in the
six-month period ended May 31, 2001. The increase in net revenues is primarily
attributable to

         -    An increase in United States sales of approximately $734,000, from
              approximately $1,247,000 in the first two quarters of fiscal 2000
              to approximately $1,981,000 in the first two quarters of fiscal
              2001. This increase is primarily attributable to increased sales
              of the disposable SomaSensor, increased sales of the Cerebral
              Oximeter, and initial purchases of demonstration equipment by
              independent sales representatives.

         -    a 16% increase in the average selling price of Cerebral Oximeters,
              and a 10% increase in the average selling price of SomaSensors,
              primarily as a result of a change in the sales mix between sales
              in the United States and sales to international distributors, and
              a change in the United States sales mix between direct sales of
              the Cerebral Oximeter and no-cap placements of the Cerebral
              Oximeter.

The increase in net revenues was partially offset by a decrease in international
sales of approximately $503,000, from approximately $1,220,000 in the first two
quarters of fiscal 2000 to approximately $717,000 in the first two quarters of
fiscal 2001. This decrease is primarily due to reduced purchases by Baxter
Limited in Japan, the initial stocking order for model 4100 and model 5100
Cerebral Oximeters and SomaSensors by Tyco Healthcare AG in the second quarter
of fiscal 2000, and delays in marketing the Cerebral Oximeter in 39 markets,
including Europe, in fiscal 2001.

         Approximately 27% of our net revenues in the first two quarters of
fiscal 2001 were export sales, compared to approximately 49% of our net revenues
in the first two quarters of fiscal 2000. Sales of SomaSensors, model 4100
Cerebral Oximeters, model 5100 Cerebral Oximeters, and model 4100 exchanges as a
percentage of net revenues were as follows:

         One international distributor accounted for approximately 13% of net
revenues for the six months ended May 31, 2001, and two international
distributors accounted for approximately 19% and 17%, respectively, of net
revenues for the six months ended May 31, 2000.

         Gross margin as a percentage of net revenues was approximately 62% for
the six months ended May 31, 2001 and approximately 51% for the six months ended
May 31, 2000. The increase in gross margin as a percentage of net revenues is
primarily attributable to a 16% increase in the average selling price of
Cerebral Oximeters, and a 10% increase in the average selling price of
SomaSensors described above.

         Our research, development and engineering expenses increased
approximately $187,000, or 87%, from $215,526 for the six months ended May 31,
2000 to $402,104 for the six months ended May 31, 2001. The increase is
primarily attributable to a $193,000 increase in costs associated with the
development of the CorRestore patch.

     Selling, general and administrative expenses decreased approximately
$1,000, from $2,852,865 for the six months ended May 31, 2000 to $2,851,677 for
the six months ended May 31, 2001. The decrease in selling, general and
administrative expense is primarily attributable to

         -    a $166,000 decrease in travel and selling-related expenses
              primarily related to reduced trade show and travel expenses,

         -    a $155,000 decrease in salaries, wages, commissions and related
              expenses, primarily as a result of a reduction in the number of
              employees, principally sales and marketing, since June 1, 2000
              (from an average of 42 employees for the six months ended May 31,
              2000 to an average of 34 employees for the six months ended May
              31, 2001), and

         -    an $84,000 decrease in incentive compensation expense primarily
              due to our executive officers not participating in the 2001
              Employee Incentive Compensation Plan in exchange for a grant of
              stock options.

                             SOMANETICS CORPORATION

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

                                  MAY 31, 2001

These decreases were partially offset by

         -    a $200,000 termination fee related to the Kingsbridge Capital
              Limited Private Equity Line,

         -    a $110,000 increase in intangible amortization expense related to
              the amortization of license acquisition costs, and

         -    $45,000 in connection with the Loan and Security Agreement with
              Crestmark Bank.

         For the six-month period ended May 31, 2001, we realized a 14% decrease
in our net loss over the same period in fiscal 2000. The decrease is primarily
attributable to

         -    a 9% increase in net revenues,

         -    an 11% increase in gross margin percentage, and

         -    a $55,000 decrease in realized losses on sales of securities due
              to a realized loss on the sale of marketable securities in the
              second quarter of fiscal 2000.

The decreased net loss was achieved despite

         -    a 6% increase in operating expenses, and

         -    an approximately $44,000 decrease in interest income, primarily
              due to the absence of marketable securities for fiscal 2001.


LIQUIDITY AND CAPITAL RESOURCES

         Net cash used in operations during the six-month period ended May 31,
2001 was approximately $1,319,000. Cash was used primarily to

         -    fund our net loss, primarily selling, general and administrative
              expenses and research, development and engineering expenses,
              totaling approximately $1,306,000, before depreciation and
              amortization expense,

         -    increase inventories by approximately $464,000, primarily due to a
              depletion of inventory resulting from fourth quarter 2000 sales,
              and the purchase of components related to our new generation
              SomaSensor, and

         -    decrease accrued liabilities by approximately $131,000 as a result
              of payments made in fiscal 2001.

These uses of cash were partially offset by a decrease in accounts receivable of
approximately $540,000, primarily because of lower second quarter 2001 sales
than fourth quarter 2000 sales.

         We expect our working capital requirements to increase if sales
increase. Capital expenditures in the first six months of fiscal 2001 were
approximately $113,000. Approximately $64,000 of these expenditures were for
Cerebral Oximeter demonstration units and no-cap units, and approximately
$49,000 of these expenditures were for manufacturing tooling for our new
generation SomaSensor. We expect our capital requirements to increase as a
result of the costs of developing and testing the CorRestore patch.

                             SOMANETICS CORPORATION

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

                                  MAY 31, 2001

         On December 4, 2000, we completed the sale of 112,994 common shares to
Kingsbridge Capital Limited, at a price of $1.77, for gross proceeds of
$200,000. Our net proceeds, after deducting the commissions and the estimated
expenses of the offering, were approximately $187,000. Effective March 5, 2001,
we de-registered the remaining shares originally registered for resale by
Kingsbridge under the Private Equity Line Agreement, because we no longer intend
to sell any more shares to Kingsbridge, except upon any exercise of its warrant,
and Kingsbridge is no longer publicly offering for resale the shares subject to
the warrant we granted to them. On April 10, 2001, we mutually agreed with
Kingsbridge to terminate the Private Equity Line Agreement, the related
Registration Rights Agreement, and Kingsbridge's right to the discount on any
unsold shares, in exchange for our payment of $200,000 to Kingsbridge.

         On February 13, 2001, we entered into a Loan and Security Agreement
with Crestmark Bank for a working capital line of credit for up to $750,000,
collateralized by all of our assets. Under the agreement, Crestmark Bank may,
but is not obligated to, lend us amounts we request from time to time, up to
$750,000, if no default exists. The loans are limited by a borrowing base based
on qualifying accounts receivable and lender reserves. The loan is payable on
demand, and our collections of our receivables are directed to Crestmark Bank in
payment of any outstanding balance of the loan.

         The principal amount outstanding bears interest, payable monthly, at
the prime rate (6.75% at July 2, 2001) plus 2% plus a 2.4% service fee, and we
paid a $45,000 commitment fee for the loan. Through May 31, 2001, we have
borrowed $920,050 under the agreement and repaid $920,050 in principal amount
through Crestmark's collection of our receivables, and by using some of the
proceeds from our April 9, 2001 offering. As of May 31, 2001, $628,629 was
available for borrowing, at Crestmark's discretion, under the facility. We have
agreed to use the proceeds of the loans solely as working capital. The line of
credit requires us to maintain minimum tangible net worth of $500,000 and a
ratio of total liabilities to tangible net worth not to exceed 3:1. The line of
credit terminates upon Crestmark's demand.

         On April 9, 2001, we completed the private placement of 1,325,000
newly-issued common shares at a price of $1.75 per share, for gross proceeds of
$2,318,750. Our estimated net proceeds, after deducting the placement agent's
commission and the estimated expenses of the offering, were approximately
$2,159,000. Brean Murray & Co., Inc. was our exclusive placement agent for the
offering and received for its services (1) $104,362.50 as a placement agent fee,
and (2) warrants to purchase 25,000 common shares at $2.10 per share exercisable
during the four-year period beginning April 9, 2002. A. Brean Murray, one of our
directors, and his wife control Brean Murray & Co., Inc. In addition, the Brean
Murray & Co., Inc. Profit Sharing Plan purchased 32,285 common shares in the
offering, and Robert R. Henry, one of our directors, purchased 100,000 common
shares in the offering.

         As of May 31, 2001, we had working capital of $2,319,770, cash and cash
equivalents of $1,036,141, total current liabilities of $654,383 and
shareholder's equity of $3,668,036.

         Assuming the FDA requires 510(k) clearance and not PMA approval for the
CorRestore patch, and human clinical trials are not required, we expect the
process of development, testing, application, clearance and preparing to
manufacture the product to take approximately one year and to cost us
approximately $750,000. If the 510(k) process requires human clinical trials, we
expect the process of development, testing, application, clearance and preparing
to manufacture the product to take approximately two years and to cost us
approximately $1,500,000.

                             SOMANETICS CORPORATION

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS

                                  MAY 31, 2001

         We believe that the cash and cash equivalents on hand at May 31, 2001,
together with the estimated net borrowings available under the Crestmark Bank
Loan and Security Agreement, will be adequate to satisfy our operating and
capital requirements through the second quarter of fiscal 2002. By that time we
will be required to raise additional cash either through additional sales of our
products, through sales of securities, by incurring indebtedness or by some
combination of these alternatives. If we are unable to raise additional cash by
that time, we will be required to reduce or discontinue our operations.

         The estimated length of time current cash and cash equivalents will
sustain our operations is based on estimates and assumptions we have made. These
estimates and assumptions are subject to change as a result of actual
experience. Actual capital requirements necessary to market the Cerebral
Oximeter and SomaSensor, to develop and test the CorRestore patch, to undertake
other product development activities, and for working capital might be
substantially greater than current estimates.

         We do not believe that product sales will be sufficient to fund our
operations in fiscal 2001. Although we expect to incur an operating loss for
fiscal year 2001, we expect to achieve positive earnings before interest, taxes,
depreciation and amortization by the fourth quarter of fiscal 2001.

         The underwriter of the June 1997 public offering received warrants to
purchase 200,000 common shares exercisable at $4.80 per share until May 29,
2002. In addition, Kingsbridge Capital Limited has warrants to purchase 203,108
common shares exercisable at $4.29 per share until September 3, 2005 pursuant to
the Private Equity Line Agreement. Also, CorRestore, LLC and its agent, Wolfe &
Company, received warrants to purchase 400,000 common shares exercisable at
$3.00 per share until June 2, 2005 pursuant to the CorRestore license agreement,
and when specified events occur we agreed to issue them five-year warrants to
purchase an additional 2,100,000 common shares exercisable at $3.00 per share
pursuant to the CorRestore license agreement. Also, as described above, the
placement agent in the April 9, 2001 private placement received warrants to
purchase 25,000 common shares exercisable at $2.10 per share until April 9,
2006. It is unlikely that these warrants will be exercised if the exercise price
exceeds the market price of the common shares.

         We are a party to the Loan and Security Agreement with Crestmark Bank
described above. As of July 2, 2001, we had no outstanding principal loan
balance, and $495,830 was available for borrowing, at Crestmark's discretion,
under the facility. We do not have any other loan commitments.

         Even if we receive additional capital, we might not be able to achieve
the level of sales necessary to sustain our operations, and we will incur the
costs of developing and testing the CorRestore patch before we realize any
revenues from the patch. We might not be able to obtain any funds on terms
acceptable to us and at times required by us through sales of our products,
sales of securities or loans in sufficient quantities. Our Independent Auditors'
report in our Annual Report on Form 10-K for the fiscal year ended November 30,
2000 contains an explanatory paragraph relating to an uncertainty concerning our
ability to continue as a going concern.
