             ADVANCED NEUROMODULATION SYSTEMS, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1)  BUSINESS/NEW ACCOUNTING STANDARDS

     Advanced Neuromodulation Systems, Inc. (the "Company" or "ANS") designs,
     develops, manufactures and markets implantable neuromodulation devices used
     to manage chronic intractable pain and other disorders of the central
     nervous system. We also provide contract development and custom
     manufacturing for other medical device companies through our Hi-tronics
     Designs, Inc. ("HDI") subsidiary, which we acquired in January 2001. See
     Note 3. ANS neuromodulation revenues are derived primarily from sales
     throughout the United States, Europe and Australia while HDI revenues are
     derived within the United States.

     The research and development, manufacture, sale and distribution of medical
     devices are subject to extensive regulation by various public agencies,
     principally the Food and Drug Administration and corresponding state, local
     and foreign agencies. Product approvals and clearances can be delayed or
     withdrawn for failure to comply with regulatory requirements or the
     occurrence of unforeseen problems following initial marketing.

     In addition, ANS products are purchased primarily by hospitals and other
     users who then bill various third party payers including Medicare,
     Medicaid, private insurance companies and managed care organizations. These
     third party payers reimburse fixed amounts for services based on a specific
     diagnosis. The impact of changes in third party payer reimbursement
     policies and any amendments to existing reimbursement rules and regulations
     that restrict or terminate the eligibility of ANS products could have an
     adverse impact on the Company's financial condition and results of
     operations.

     In June 2001, the Financial Accounting Standards Board issued Statement of
     Financial Accounting Standards No. 141 ("SFAS 141"), "Business
     Combinations" and Statement of Financial Accounting Standards No. 142
     ("SFAS 142"), "Goodwill and Other Intangible Assets." SFAS 141 and SFAS 142
     are effective for fiscal years beginning after December 15, 2001. Under the
     new rules, goodwill and intangible assets deemed to have indefinite lives
     will no longer be amortized but will be subject to annual impairment tests
     in accordance with the statements. Other intangible assets will continue to
     be amortized over their useful lives. The Company adopted SFAS 141 and SFAS
     142 on January 1, 2002 and eliminated amortization of goodwill as of such
     date. Amortization expense for goodwill for the three months ended March
     31, 2001 was $139,151. The pro forma impact on net income (loss) and net
     income (loss) per share for the three months ended March 31, 2001 compared
     to the actual results for the three months ended March 31, 2002 is as
     follows:

(2)  CONDENSED FINANCIAL STATEMENTS

     The unaudited consolidated financial information contained in this report
     reflects all adjustments (consisting of normal recurring accruals)
     considered necessary, in the opinion of management, for a fair presentation
     of results for the interim periods presented. The preparation of financial
     statements in conformity with generally accepted accounting principles
     requires management to make estimates and assumptions that affect the
     reported amounts of assets and liabilities and disclosure of contingent
     assets and liabilities at the date of the financial statements and the
     reported amounts of revenues and expenses during the reporting period.
     Actual results could differ from these estimates.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

     Certain information and footnote disclosures normally included in financial
     statements prepared in accordance with generally accepted accounting
     principles have been condensed or omitted. These financial statements
     should be read in conjunction with the financial statements and notes
     thereto included in the Company's December 31, 2001 Annual Report on Form
     10-K. The results of operations for the period ended March 31, 2002 are not
     necessarily indicative of operations for the full year.

     The consolidated financial statements include the accounts of Advanced
     Neuromodulation Systems, Inc. and its subsidiaries. All significant
     intercompany balances and transactions have been eliminated in
     consolidation.

(3)  ACQUISITIONS

     On January 2, 2001, the Company acquired the assets of Implantable Devices
     Limited Partnership (IDP) and ESOX Technology Holdings, LLC (ESOX), two
     privately held Minnesota companies, for 119,100 shares of the Company's
     common stock. Based on the closing price of ANS common stock on December
     29, 2000, the value of the stock issued to acquire the assets was $2.43
     million. The assets purchased consisted primarily of intellectual property
     and technology for the fully implantable constant-rate infusion pump that
     ANS has developed. Prior to the acquisition, the Company had licensed
     rights to the technology only for pain and cancer therapy applications.

     Also on January 2, 2001, the Company completed the acquisition of
     Hi-tronics Designs, Inc. (HDI), a privately-held contract developer and
     original equipment manufacturer (O.E.M.) of electro-mechanical devices with
     headquarters in Budd Lake, New Jersey. The Company acquired all of HDI's
     outstanding stock through a merger in exchange for 1,104,725 shares of ANS
     common stock. The transaction was accounted for on a pooling of interests
     basis. HDI developed and manufactured the Company's totally implantable
     pulse generator (IPG) used in the treatment of chronic intractable pain and
     was also the O.E.M. manufacturer of the transmitter used with the Company's
     Renew radio-frequency spinal cord stimulation system.

     Prior to the Company's acquisition of HDI, HDI's fiscal year ended on
     November 30. Beginning in 2001, the fiscal year-ends have been conformed to
     December 31. As a result, the results of operations of HDI for the
     one-month period ending December 31, 2000 have been recorded directly to
     retained earnings in the Consolidated Statement of Stockholders' Equity for
     the period ended December 31, 2001 and are not reflected in the
     Consolidated Statements of Income.

(4)  NOTE PAYABLE

     In connection with the acquisition of HDI (see Note 3), the Company
     assumed responsibility for a note payable with a principal balance of
     $177,028 at March 31, 2002. The note was entered into during March 2000,
     has a five-year term, and bears interest at a fixed rate of 9 percent per
     annum. The monthly installments for principal and interest are $5,623. The
     loan is collateralized by the equipment purchased from the proceeds of the
     note and accounts receivable of HDI. Maturities of the note payable are as
     follows: $39,631 in 2002, $57,304 in 2003, $62,738 in 2004 and $17,355 in
     2005.

     Estimated fair value for the real estate investment trust is determined by
     the closing price as reported on the New York Stock Exchange at each
     financial reporting period. In the case of the investment grade municipal
     bonds and FNMA and Federal Home Loan Bank notes, the brokerage firms
     holding such bonds and notes provide the values at each reporting period by
     utilizing a standard pricing service.

     At March 31, 2002, no individual security represented more than 20 percent
     of the total portfolio or 1 percent of total assets. The Company did not
     have any investments in derivative financial instruments at March 31, 2002.

(6)  COMMITMENTS AND CONTINGENCIES

     The Company entered into a sixty-three month lease agreement on its 40,000
     square feet corporate headquarters and manufacturing facility in Plano,
     Texas during February 1999. The Company relocated its operations to the
     leased facility in May 1999 and the rental period under the lease commenced
     on June 1, 1999. Under the terms of the lease agreement, the Company
     received three months free rent and the monthly rental rate for the
     remaining term of the lease is $48,308. The monthly rental rate includes
     certain operating expenses such as property taxes on the facility,
     insurance, landscape and maintenance and janitorial services. The Company
     also has the first right of refusal to acquire the facility.

     The Company also leases facilities in New Jersey as a result of the January
     2001 acquisition of HDI. One of the facilities, located in Budd Lake, New
     Jersey is 8,800 square feet of office space that is used for
     administration, design engineering, drafting, documentation and regulatory
     affairs. The lease expires on May 31, 2003 and has a monthly rental rate of
     $10,891.The Company also leases 15,000 square feet of space in
     Hackettstown, New Jersey used for the O.E.M. manufacturing operations. The
     Hackettstown lease, which expires on December 31, 2002, has a monthly
     rental rate of $9,636 and is renewable for two additional one-year periods.
     In addition, during January 2001, the Company leased 2,200 square feet of
     additional space in the Hackettstown facility adjacent to the 15,000 square
     feet of manufacturing space until June 30, 2002 at a monthly rental rate of
     $2,269.

     The Company leases transportation equipment under non-cancelable operating
     leases until May 2002 at a monthly rate of $1,472.

     The Company leases office equipment under non-cancelable operating leases
     expiring through 2004. Monthly payments on the office equipment leases are
     $3,600.

     The Company is a party to product liability claims related to ANS
     neurostimulation devices. Product liability insurers have assumed
     responsibility for defending the Company against these claims. While
     historically product liability claims for ANS neurostimulation devices have
     not resulted in significant monetary liability for the Company beyond its
     insurance coverage, there can be no assurances that the Company will not
     incur significant monetary liability to the claimants if such insurance is
     inadequate, and there can be no assurance that the Company's
     neurostimulation business and future ANS product lines will not be
     adversely affected by these product liability claims.

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

     Except for such product liability the Company is not currently a party to
     any other pending legal proceeding. The Company maintains general liability
     insurance against risks arising out of the normal course of business.

(7)  INCOME TAXES

     The Company recorded income tax expense during the three months ended March
     31, 2002 of $471,449, an overall effective tax rate of 36.0%. This
     effective tax rate is higher than the U.S. statutory rate of 34% for
     corporations due to a provision for state taxes. During the three months
     ended March 31, 2001, the Company recorded a tax benefit of $6,899. The
     effective tax rate in 2001 of 52.4% was higher than the U.S. statutory rate
     of 34% because the Company's 2001 expense for goodwill is not deductible
     for tax purposes, and, when combined with a provision for state taxes,
     results in the higher effective tax rate. In addition, approximately
     $234,000 of the $484,000 of costs incurred in the acquisition of HDI
     recorded in the three month period ended March 31, 2001 are not deductible
     for tax purposes, which also contributed to the higher effective tax rate
     in 2001.

     As of December 31, 2001, the Company had a net operating loss carry forward
     of approximately $1.8 million which expires in years through 2022. As a
     result of the enactment of certain tax law changes during the first
     quarter, the Company will carry back approximately $1.6 million of net
     operating losses resulting in carry forwards which consist primarily of net
     operating losses acquired from HDI. This net operating loss carry forward
     may be subject to Section 382 of the Internal Revenue Code or other
     provisions which may limit the use of the net operating loss carry forward
     in any tax year.

(8)  NET INCOME PER SHARE

     Basic net income per share is computed based only on the weighted average
     number of common shares outstanding during the period. Diluted net income
     per share is computed using the additional dilutive effect, if any, of
     stock options and warrants using the treasury stock method based on the
     average market price of the stock during the period. The following table
     presents the reconciliation of basic and diluted shares:

     For the three months ended March 31, 2002, the incremental shares used for
     dilutive income per share relate to stock options whose exercise price was
     less than the average market price in the underlying quarterly
     computations. For the three months ended March 31, 2002, all stock options
     were included in the computation of diluted income per share since all
     exercise prices were less than the average market price of the common
     shares for that three-month period. For the three months ended March 31,
     2001, no options were included in the computation of diluted income per
     share because the effect would be antidilutive.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

The following discussion of the financial condition and results of operations of
the Company should be read in conjunction with the Consolidated Financial
Statements of the Company and the related Notes.

OVERVIEW

We design, develop, manufacture and market neuromodulation devices for patients
suffering from chronic pain. Neuromodulation devices include implantable
neurostimulation devices, which deliver electric current directly to targeted
nerves, and implantable infusion pumps, which deliver small, precisely
controlled doses of drugs directly to targeted sites within the body. We also
provide contract development and custom manufacturing for other medical device
companies through our Hi-tronics Designs, Inc. subsidiary, which we acquired in
January 2001. See Note 3.

The use of neuromodulation devices is growing rapidly. According to an
independent industry study, the worldwide market for neuromodulation products
was approximately $525 million in 2001, up 21% from the previous year. This
study estimates that the market will grow to approximately $1.1 billion
worldwide by 2005, based solely on currently approved treatment indications in
the U.S. for neuromodulation devices.

Our principal neurostimulation product in 2001 was Renew(R), our latest
generation radio-frequency (RF) spinal cord stimulation device. We have sold
Renew in the U.S. since June 1999 for treatment of chronic pain of the trunk and
limbs.

On November 21, 2001, the U.S. Food and Drug Administration (FDA) approved our
Genesis(TM) totally implantable pulse generator (IPG) spinal cord stimulation
device. We began selling Genesis in Europe in the first quarter of 2001 and in
the U.S. and Australia in January 2002 for the treatment of chronic pain of the
trunk and limbs. Until our launch of the Genesis IPG, only one other company
marketed an approved IPG device in the United States.

In 2000, we completed development of AccuRx, our constant rate implantable drug
pump, in part using proprietary technology we licensed from Implantable Devices
Limited Partnership (IDP). We initiated clinical trials of AccuRx under an
Investigational Device Exemption (IDE) in the first quarter of 2001, and began
selling AccuRx in certain international markets in the second quarter of 2001.
On January 2, 2001, we strengthened our position in the neuromodulation market
by acquiring the assets of IDP and ESOX Technology Holdings, LLC (ESOX) for
119,100 shares of our common valued at approximately $2.43 million. This
acquisition provided us with intellectual property surrounding implantable drug
pump technologies in all applications, including pain and cancer therapy.

Also, on January 2, 2001, we completed the acquisition of Hi-tronics Designs,
Inc. (HDI), a privately-held O.E.M. developer and manufacturer, for
approximately 1.1 million shares of our common stock. We accounted for this
acquisition using the pooling method and, accordingly, the financial information
for all periods prior to the acquisition has been restated. Prior to the

                                       14
<PAGE>

acquisition, HDI developed and manufactured our Genesis IPG, as well as the
transmitter for our Renew system. Acquiring HDI provided us with additional
in-house expertise in the design and manufacture of highly sophisticated
electromechanical devices. Combined with our capabilities in the design and
manufacture of implantable leads, electronic device control and communication
systems and implantable drug pumps, we believe HDI's expertise will allow us to
develop more sophisticated products in less time. Additionally, HDI continues to
provide contract development and manufacturing services to third parties, which
we report as a separate segment for financial reporting purposes (the O.E.M.
segment). In the quarter ended March 31, 2002, our O.E.M. segment provided $2.48
million or 21.7% of our total revenue. We expect our O.E.M. segment revenue to
decrease as a percentage of our total revenue in the future, as we grow revenue
from our proprietary neurostimulation systems and drug pumps and increasingly
utilize HDI's research and development capabilities for internal product
development.

Our current neuromodulation product line includes our Genesis IPG system, Renew
RF system and AccuRx constant rate drug pump. With the launch of Genesis, we now
compete in 100% of the implantable neurostimulation market to treat chronic pain
of the trunk and limbs. Although Renew and Genesis are targeted toward treatment
of different chronic pain conditions, sales growth of Renew has slowed since the
launch of Genesis. Though it is too early to accurately predict future sales
trends, management believes it possible that sales of Renew may plateau or even
decline modestly, at least in the near term.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

General

Our discussion and analysis of our financial condition and results of operations
are based upon our consolidated financial statements, which have been prepared
in accordance with accounting principles generally accepted in the U.S. The
preparation of these financial statements requires management to make estimates
and judgments that affect the reported amounts of assets, liabilities and
related disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period. On an on-going basis, management evaluates its estimates
and judgments, including those related to product returns, bad debts,
inventories, intangible assets, warranty obligations and contingencies and
litigation. Management bases its estimates on historical experience and on
various other factors that are believed to be reasonable under the
circumstances, the results of which form the basis for making judgments about
the carrying value of assets and liabilities that are not readily apparent from
other sources. Actual results may differ from these estimates under different
assumptions or conditions.

Management believes the following critical accounting policies involve its more
significant judgments and estimates used in preparation of its consolidated
financial statements.

Revenue Recognition

Revenue from the sale of our neuromodulation products and custom manufactured
O.E.M. products is recognized when the goods are shipped to our customers. We
record, as a reduction in revenue, a provision for estimated sales returns and
allowances on these product

                                       15
<PAGE>

sales in the same period as the related revenue is recorded. These estimates are
based on historical sales returns, analysis of credit memo data and other known
factors. If the historical data we use to calculate these estimates does not
properly reflect future returns, revenue could be overstated.

We also design and develop products under fixed price development agreements
with third parties. Each development agreement reflects the terms and conditions
of the project, including project objectives, product specifications,
responsibilities for tasks, licenses and fields of use of intellectual
properties, manufacturing rights and compensation, among other terms and
conditions. A typical development project will take one to two years to complete
and is undertaken in accordance with the FDA's Quality System Regulations, which
address design controls and methods, facilities and quality assurance controls
used in manufacturing medical devices, and similar international standards. We
recognize revenue and profit under the development agreements using the
percentage-of-completion method, which relies on estimates of total expected
revenue and costs. We follow this method since reasonably dependable estimates
of revenue and costs applicable to various stages of a development agreement can
be made. If we do not accurately estimate the resources required or the scope of
work to be performed under a development agreement, then future profit margins
and results of operations may be negatively impacted.

In certain cases, we will undertake a development project on a cost plus basis.
In these cases, we invoice the customer for actual time and material expended on
the project at predetermined hourly billing rates and mark ups.

Bad Debt

We are required to estimate the collectibility of our trade receivables. A
considerable amount of judgment is required in assessing the ultimate
realization of the receivables including the current credit-worthiness of each
customer. If the financial condition of our customers were to deteriorate,
resulting in an impairment of their ability to make payments, additional
allowances or write-offs may be required.

Inventory

Our reserve for excess and obsolete inventory is based upon forecasted demand
for our products. If the demand for our products is less favorable than those
projected by management, additional inventory write-downs or write-offs may be
required.

Intangible Assets

Goodwill associated with the excess purchase price over the fair value of assets
acquired was amortized using the straight-line method through December 31, 2001
over the estimated life of 20 years.

On January 1, 2002, we adopted Statement of Financial Accounting Standards No.
141, "Business Combinations" and Statement of Financial Accounting Standards No.
142, "Goodwill and Other Intangible Assets". Under the new accounting rules,
goodwill and intangible assets deemed to have indefinite lives are no longer
amortized but will be subject to annual impairment tests in accordance with the
statements. We determined that our

                                       16
<PAGE>

goodwill at December 31, 2001 was unimpaired and eliminated amortization of the
goodwill effective January 1, 2002. Prior to adoption of these statements, our
amortization expense for goodwill was $139,151 per quarter, or $556,604 on an
annual basis.

Other identifiable intangible assets, such as patents, purchased technology,
trademarks and covenants not to compete, are currently amortized on the
straight-line method over their estimated useful lives.

In assessing the recoverability of our intangible assets, we must make
assumptions regarding estimated future cash flows and other factors to determine
the fair value of the respective assets. If these estimates or their related
assumptions change in the future, we may be required to record impairment
charges for these assets not previously recorded.

Warranty Obligations

Our products are generally covered by a one-year warranty. We accrue a warranty
reserve for estimated costs to provide warranty services. Our estimate of costs
to service our warranty obligations is based on historical experience and
expectation of future conditions. To the extent we experience increased warranty
claim activity or increased costs associated with servicing those claims, our
warranty accrual will increase resulting in decreased gross profit.

Contingencies

We are subject to proceedings, lawsuits and other claims related to our products
and business. We are required to assess the likelihood of any adverse judgments
or outcomes to these matters, as well as potential ranges of probable losses. A
determination of the amount of reserves required, if any, for these
contingencies is made after careful analysis of each individual issue. The
required reserves may change in the future due to new developments in each
matter or changes in approach, such as a change in settlement strategy, in
dealing with these matters.

Currently, product liability claims are the only litigation to which we are a
party. While historically our product liability claims have not resulted in
significant monetary liability beyond our insurance coverage, an adverse
judgment beyond our insurance coverage could have a material adverse impact on
our results of operations and financial condition.

RESULTS OF OPERATIONS

Comparison of the Three Months Ended March 31, 2002 and 2001

We reported net income of $837,000, or $.08 per diluted share, for the three
months ended March 31, 2002, compared to a net loss of $6,300 or $.00 per
diluted share in the same 2001 period. Results for the first quarter of 2002
reflect the U.S. launch of our Genesis IPG system. The net loss during the 2001
period included $484,000 of expense for costs associated with our acquisition of
HDI in January 2001. These costs were expensed instead of capitalized because
the acquisition is accounted for under the pooling of interests method.
Excluding such acquisition related costs, on a pro forma basis, net income was
$269,000, or $.03 per diluted share, for the three-month period ended March 31,
2001.

                                       17
<PAGE>

Net revenue increased 37.5% to $11.47 million for the three months ended March
31, 2002, compared to $8.34 million in the comparable 2001 period. Net revenue
of our neuromodulation products increased 41.8% to $9.00 million in 2002 from
$6.34 million in 2001 due to the U.S. launch of our Genesis IPG system. Net
revenue from our O.E.M. business increased 24.1% to $2.48 million in 2002 from
$2.00 million in 2001 due to higher volume of O.E.M. product sales and contract
engineering fees.

Gross profit increased to $6.96 million during the three months ended March 31,
2002 from $4.77 million in 2001, principally due to the increase in net revenue
discussed above. Additionally, gross profit margins increased to 60.7% in 2002,
compared to 57.2% in 2001, due to higher sales of our neuromodulation products,
which contribute higher margins than O.E.M. product sales, and operational
efficiencies from higher manufacturing volumes.

Total operating expenses increased to $5.72 million for the three months ended
March 31, 2002 from $4.44 million in the same period during 2001. However, as a
percentage of net revenue, these expenses decreased to 49.9% in 2002 from 53.2%
in 2001 due to elimination of goodwill amortization and leveraging of research
and development expense.

Research and development expense increased to $1.29 million, or 11.3% of net
revenue, during the three months ended March 31, 2002, from $1.15 million, or
13.8% of net revenue, during the same period in 2001. This increase in the
absolute dollar amount in 2002 compared to 2001 was the result of higher salary
and benefit expense from staffing additions, annual salary increases, and higher
test material expense. Our development efforts continue to be focused on
next-generation IPG stimulation systems, next-generation RF stimulation systems,
an IPG stimulation systems for deep brain stimulation to address essential
tremor and Parkinson's Disease, next generation drug pumps, and clinical trials
of our AccuRx.

Sales and marketing expense, as a percentage of net revenue, increased to 25.2%
during the three months ended March 31, 2002 from 24.7% in the same 2001 period,
and the absolute dollar amount increased to $2.90 million in 2002 from $2.06
million during 2001. This increase in the absolute dollar amount during 2002
compared to 2001 was principally attributable to higher salary and benefit
expense from staffing additions in direct sales, reimbursement and sales support
positions, annual salary increases, higher commission expense from increased
product sales, and higher sample and promotional expense in support of the
Genesis IPG launch.

General and administrative expense, as a percentage of net revenue, increased to
11.4% during the three months ended March 31, 2002 from 11.0% in the same 2001
period, and the absolute dollar amount increased to $1.30 million in 2002 from
$918,000 during 2001. This increase in the absolute dollar amount of $384,000
during 2002 compared to 2001 was principally attributable to higher salary
expense from staffing additions, annual salary increases, higher employee
benefit costs and increased legal costs.

No amortization expense of goodwill was recorded during the three months ended
March 31, 2002 due to the adoption of Statement of Financial Accounting
Standards No. 141 and Statement of Financial Accounting Standards No. 142 on
January 1, 2002. For the three months ended March 31, 2001, we recorded $139,000
of amortization expense for goodwill.

                                       18
<PAGE>

Amortization of other intangibles increased to $228,000 during the three months
ended March 31, 2002 from $173,000 in the same period in 2001, due to additional
patent amortization.

Other income increased to $69,000 during the three months ended March 31, 2002
from an expense of $346,000 during the three months ended March 31, 2001
primarily as a result of the $484,000 of expense associated with the acquisition
of HDI.

Income tax expense increased to $471,000 during the three months ended March 31,
2002 from a tax benefit of $6,900 for the same period in 2001. The 2001 period
reflects a loss before income taxes of $13,000 due to the costs associated with
the acquisition of HDI recorded in the first quarter of 2001.

LIQUIDITY AND CAPITAL RESOURCES

At March 31, 2002 our working capital increased to $26.93 million from $24.91
million at December 31, 2001. The ratio of current assets to current liabilities
was 6.32:1 at March 31, 2002, compared to 4.77:1 at December 31, 2001. Cash,
cash equivalents and marketable securities totaled $10.82 million at March 31,
2002 compared to $11.94 million at December 31, 2001.

We increased our investment in inventories to $10.45 million at March 31, 2002,
from $9.75 million at December 31, 2001. This increase from year-end 2001 was
primarily additional inventory to support our market launch of the Genesis IPG
including consignment inventory for additional sales agents to whom we provide
approximately $30,000 in consignment inventory each.

We spent $351,000 during the three months ended March 31, 2002 for capital
expenditures for additional equipment and fixtures. These expenditures consisted
primarily of additional tooling, molds and test equipment for new parts and
products we developed, and furniture and data processing equipment for new
personnel we have hired. We expect capital expenditures for the remainder of
fiscal 2002 to approximate $2.1 million.

We received $399,000 of cash during the three months ended March 31, 2002 from
the exercise of 63,111 stock options.

We believe our current cash, cash equivalents, marketable securities and cash
generated from operations will be sufficient to fund our current operating needs
and capital expenditures for the foreseeable future. We currently have no credit
facilities in place. If we decide to acquire complementary businesses, product
lines or technologies, or enter into joint ventures or strategic alliances that
require substantial capital, we intend to finance those activities by the most
attractive alternative available, which could include bank borrowings, or the
issuance of debt or equity securities.

On April 24, 2002, we filed a registration statement with the Securities and
Exchange Commission to register for issuance and sale by us through underwriters
of up to 2,875,000 shares of common stock, which includes 375,000 shares subject
to an over-allotment option granted to the underwriters. This registration
statement has not yet become effective. The securities may not be sold, nor may
offers to buy be accepted, prior to the time the

                                       19
<PAGE>

registration statement becomes effective. We plan to use the net proceeds from
this offering, if and when completed, to expand our worldwide sales and
marketing resources, to fund development of new technologies, products and
applications for existing products, to pursue regulatory approvals, and to
invest in product lines, businesses, companies, services or technologies that
complement our current business through mergers, acquisitions, joint ventures
or otherwise, as well as for working capital and other general purposes.

CASH FLOWS

Net cash used by operations was $1.06 million for the three months ended March
31, 2002, while operating activities provided cash of $755,000 during the same
period in 2001. Although we reported net earnings of $837,000 during the 2002
period compared to a net loss of $6,300 in the 2001 period, we used cash in our
operating activities during 2002 primarily for increases in accounts receivable
and inventories of $1.0 million and $705,000, respectively, and for reducing our
current liabilities by nearly $1.54 million.

Net cash used in investing activities was $717,000 for the three months ended
March 31, 2002, as compared to $1.35 million for the same period in 2001, a
decrease of $633,000. This decrease in the use of cash in investing activities
during the 2002 period compared to 2001 was the result of a $761,000 reduction
in additions to patents and intangible assets and capital expenditures for
equipment and fixtures.

Net cash provided by financing activities was $387,000 for the three months
ended March 31, 2002, as compared to $118,000 for the same period in 2001.
During the first quarter of 2002, we used $13,000 to reduce certain debt
obligations, while we received $399,000 from the exercise of stock options.
During the first quarter of 2001, we used $12,000 to reduce our obligations
under certain debt agreements, while we received $130,000 from the exercise of
stock options.

CURRENCY FLUCTUATIONS

Substantially all of our international sales are denominated in U.S. dollars.
Fluctuations in currency exchange rates in other countries could reduce the
demand for our products by increasing the price of our products in the currency
of the countries in which the products are sold, although we do not believe
currency fluctuations have had a material effect on the Company's results of
operations to date.

OUTLOOK AND UNCERTAINTIES

The following is a "safe harbor" statement under the Private Securities
Litigation Reform Act of 1995: The matters discussed in this Quarterly Report on
Form 10-Q contain statements that constitute forward-looking statements within
the meaning of Section 21E of the Securities Exchange Act of 1934, as amended.
The words "expect", "estimate", "anticipate", "predict", "believe", "plan",
"will", "should", "intend", "potential", "new market", "potential market
applications" and similar expressions and variations thereof are intended to
identify forward-looking statements. Such statements appear in a number of
places in this Quarterly Report on Form 10-Q and include statements regarding
our intent, belief or current expectations with respect to, among other things:
(i) trends affecting our financial condition or results of operations; (ii) our
financing plans; and (iii) our business growth strategies. We caution our
readers that any forward-looking statements are not guarantees of future
performance and involve risks and uncertainties. Actual results may differ
materially from those projected in the forward-looking statements as a result of
various factors. These risks and uncertainties include the following:

o    failure of our Genesis IPG to gain market acceptance would adversely affect
     our revenue growth and profitability

o    because our main competitor has significantly greater resources than we do
     and new competitors may enter the neuromodulation market, it may be
     difficult for us to compete in this market

o    if pain management specialists do not recommend and endorse our products,
     our sales could be negatively impacted and we may be unable to increase our
     revenues and profitability

o    the launch of Genesis and other market factors could impede growth in or
     reduce sales of Renew, which would adversely affect our revenues and
     profitability

o    if patients choose less invasive or less expensive alternatives to our
     products, our sales could be negatively impacted

o    any adverse changes in coverage or reimbursement amounts by Medicare and
     Medicaid, private insurance companies and managed care organizations, or
     workers' compensation programs could limit our ability to market and sell
     our products

o    if we fail to protect our intellectual property rights, our competitors may
     take advantage of our ideas and compete directly against us

o    other parties may sue us for infringing their intellectual property rights

o    failure to obtain necessary government approvals for new products or for
     new applications for existing products would mean we could not sell those
     new products, or sell our existing products for those new applications

o    modification of any marketed device could require a new 510(k) clearance or
     PMA or require us to cease marketing or recall the modified device until we
     obtain this clearance or approval

o    we will be unable to sell our products if we fail to comply with
     manufacturing regulations

o    our products are subject to product recalls even after receiving FDA
     clearance or approval, which would negatively affect our financial
     performance and could harm our reputation

o    we are subject to potential product liability claims and we may not have
     the insurance or other resources to cover the cost of any successful claim

                                       21
<PAGE>

o    we are subject to substantial government regulation and our failure to
     comply with all applicable government regulations could subject us to
     numerous penalties, any of which could adversely affect our business

o    our reliance on single suppliers for critical components used in our main
     products could adversely affect our ability to deliver products on time

o    two distributors currently account for a significant percentage of our
     revenue from our neuromodulation products segment, and several of our
     competitors currently account for a significant percentage of our revenue
     from our O.E.M. segment

o    we are dependent upon the success of neuromodulation technology; our
     inability to continue to develop innovative neuromodulation products, or
     the failure of the neuromodulation market to develop as we anticipate,
     would adversely affect our business

o    our success will depend on our ability to attract and retain key personnel
     and scientific staff

o    if we choose to acquire complementary business, products or technologies
     instead of developing them ourselves, we may be unable to complete these
     acquisitions or to successfully integrate an acquired business, product or
     technology in a cost-effective and non-disruptive manner

o    we are subject to additional risks associated with international operations

o    our operations are conducted at three locations, and a disaster at any of
     these facilities could result in a prolonged interruption of our business

o    general economic risks

o    other risks detailed from time to time in our SEC public filings

Consequently, if our assumptions prove to be incorrect or such risks or
uncertainties materialize, anticipated results could differ materially from
those forecasted in forward-looking statements.
