      medical devices is 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      be delayed or withdrawn for failure to comply with regulatory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, the Company's products are purchased primarily by hospitals
      and other users which then bill various third party payors including
      Medicare, Medicaid, private insurance companies and managed care
      organizations. These third party payors reimburse fixed amounts for
      services based on a specific diagnosis. The impact of changes in third
      party payor reimbursement policies and any amendments to existing
      reimbursement rules and regulations which restrict or terminate the
      eligibility of the Company's products could have an adverse impact on the
      Company's financial condition and results of operations.

(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.

      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, 1996 Annual
      Report on Form 10-K. The results of operations for periods ended March 31
      are not necessarily indicative of operations for the full year.

      The consolidated financial statements include the accounts of Quest
      Medical, Inc. and subsidiaries (the "Company"). All significant
      intercompany balances and transactions have been eliminated in
      consolidation.

      At March 31, 1997, no individual security represented more than 30
      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, 1997.

(4)   CURRENT AND LONG-TERM NOTES PAYABLE

      On March 3, 1997, the Company amended its $5 million working capital line
      of credit. Under the amended agreement, the working capital line of
      credit was increased to $5,650,000 and a $350,000 term loan facility was
      added. Borrowings under the working capital line of credit bear interest
      at prime plus 100 basis points, or at the Company's option, LIBOR plus
      275 basis points. Borrowings under the term loan bear interest at prime
      plus 100 basis points, or at the Company's option, LIBOR plus 225 basis
      points. The facilities are collateralized by all of the Company's assets
      with the exception of the real property, building, and equipment that
      collateralize the long-term financing on the Allen facility described
      below. The Company is subject to certain covenants related to the loan
      agreement including the maintenance of a minimum fixed charge ratio, a
      maximum total liabilities to tangible net worth ratio, and a maximum
      margin ratio (as defined). Under the amended agreement, the Company is
      prohibited from paying cash dividends. Under the working capital line of
      credit, the Company is required to make monthly payments of $90,000 with
      interest payable quarterly. Under the term loan, no principal payments
      are due until maturity and interest is payable quarterly. These
      facilities will expire on January 31, 1998. On March 3, 1997, the company
      increased its borrowings under the working capital line of credit by
      $1,100,000 and borrowed $350,000 under the term loan facility. These
      additional borrowings were utilized to pay a portion of the debt under
      the February 6, 1997 Settlement discussed below. At March 31, 1997, the
      Company had advances in the amount of $5,560,000 outstanding under its
      working capital line with a weighted average interest rate of 8.42
      percent. At March 31, 1997, the Company had advances in the amount of
      $350,000 under the term loan facility with a weighted average interest
      rate of 7.96 percent.

      On February 21, 1997, the Company borrowed $2,000,000 from a nonaffiliate
      shareholder pursuant to a promissory note. The promissory note bears
      interest at the

                                       9                            (Continued)

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


      rate of 6 percent per annum. Under the terms of the promissory note, the
      Company is required to make quarterly interest payments with a principal
      payment of $2,000,000 due and payable at the maturity of the note on
      February 21, 1998. In conjunction with the promissory note, the Company
      issued the shareholder five-year warrants to purchase 100,000 shares of
      common stock at an exercise price of $6.50 per share, the closing sales
      price on the date the indebtedness was incurred. Under the warrant
      agreement, the shareholder has the right to one demand registration in
      addition to piggyback registration rights. The loan is subordinated to
      the bank debt described above and the shareholder has a second lien on
      all of the assets collateralizing the bank debt. Proceeds of the loan
      were utilized to pay a portion of the debt under the Settlement described
      below.

      At December 31, 1996, the Company had a short-term, noninterest-bearing
      note payable in the amount of $972,197 due in connection with certain
      purchase price adjustments (primarily tax refunds and tax credits)
      awarded through an arbitration to the former owner of Neuromed, Inc. (a
      company acquired in March 1995). The note was paid during January 1997
      from cash reserves. In addition, on February 6, 1997, the Company reached
      a Settlement (the "Settlement") on all outstanding issues with the former
      owner of Neuromed relating to the Neuromed acquisition. Under the
      Settlement, the Company agreed to pay $4.5 million in settlement of the
      earn-out provisions of the purchase agreement and the purchase of certain
      patent rights. Of the Settlement, $3.5 million was paid in the form of an
      interest-bearing note at 10.25 percent per annum from February 6, 1997
      which was due and payable on March 3, 1997. The Company paid such note on
      March 3, 1997, utilizing proceeds from the bank debt and shareholder debt
      described above. In addition, the Company issued the former owner a
      promissory note in the amount of $1,000,000. The promissory note bears
      interest at the rate of 10 percent per annum with interest payable
      monthly and a principal payment of $1,000,000 due and payable on February
      6, 1998. The loan is subordinated to the bank debt described above and is
      collateralized with a second lien that is pari passu with the
      shareholder's lien.

      At March 31, 1997, the Company had a 7.75 percent note payable for
      $159,179. This note was collateralized by certain of the Company's
      marketable security investments, held by an investment company, which had
      a carrying value of $516,875. Borrowings under this note are restricted
      to 50 percent of the market value of the Company's marketable securities
      held by the investment company. At March 31, 1997, the amount available
      for additional borrowing under this note was $99,259.

      The Company also has two agreements for long-term financing of its
      principal office and manufacturing facility in the amounts of $2,911,916
      and $1,355,071 at March 31, 1997.

           Scheduled payments of current and long-term notes payable are as
      follows:

(5)   COMMITMENTS AND CONTINGENCIES

      As a consequence of the Neuromed Acquisition in March 1995, the Company
      is a party to product liability claims related to SCS devices sold by
      Neuromed prior to the acquisition. Product liability insurers have
      assumed responsibility for defending the Company against these claims,
      subject to reservation of rights in certain cases. While historically
      product liability claims against Neuromed have not resulted in
      significant monetary liability for Neuromed 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
      unavailable or inadequate for any reason, or that the Company's SCS
      business and new SCS product lines will not be adversely affected by
      these product liability claims.

      Except for such product liability claims and other ordinary routine
      litigation incidental or immaterial to its business, 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.

(6)   INCOME TAXES

      The Company recorded income tax expense during the three months ended
      March 31, 1997, of $56,743, an effective tax rate of 37.6 percent. The
      Company's expense for amortization costs in excess of net assets acquired
      (goodwill) is not deductible for tax purposes, thus explaining the higher
      effective tax rate compared to the U.S. statutory rate for corporations
      of 34 percent. During the three months ended March 31, 1996, the Company
      recorded income tax expense of $18,347, despite incurring a loss before
      income taxes of $76,225, as a consequence of the nondeductibility of
      amortization expense of costs in excess of net assets acquired.

(7)   NEW ACCOUNTING PRONOUNCEMENT

      In February 1997, the Financial Accounting Standards Board issued
      Statement No. 128, Earnings per Share, which is required to be adopted on
      December 31, 1997. At that time, the Company will be required to change
      the method currently used to compute earnings per share and to restate
      all prior periods. Under the new requirements for calculating primary
      earnings per share, the dilutive effect of stock options will be
      excluded. Utilizing the new method would not impact primary earnings
      (loss) per share for the quarters ended March 31, 1997 or March 31, 199.
      The impact of Statement 128 on the calculation of fully diluted earnings
      (loss) per share for these quarters is not expected to be material.

(8)   RECENT EVENTS

      On March 10, 1997, the Company announced that the Company's Board of
      Directors had engaged Smith Barney and Rauscher Pierce Refsnes to seek
      strategic alternatives to enhance shareholder value. These strategic
      alternatives may include a merger, sale of assets, other business
      combination, or a joint venture or strategic alliance.

                      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 Condensed Consolidated
Financial Statements of the Company and the related Notes thereto.

RESULTS OF OPERATIONS

COMPARISON OF THE THREE MONTHS ENDED MARCH 31, 1997 AND 1996

Revenues. Net revenue of $6.67 million for the three months ended March 31,
1997 was $520,000, or 8.5 percent above the level for the comparable 1996
period of $6.15 million. This increase was primarily the result of higher unit
sales volume at the Company's Advanced Neuromodulation Systems ("ANS")
subsidiary, formerly Neuromed, which was acquired on March 31, 1995 and
provides electronic spinal cord stimulation ("SCS") devices used to manage
chronic severe pain. During the first quarter of 1996, management announced
plans to build the infrastructure and improve the current products of ANS to
transform ANS into an industry leader and compete effectively in the SCS
market. During 1996 and into the first quarter of 1997, the Company dedicated
significant engineering and marketing resources in these efforts. Management
believes these measures account for the increase in net revenue of ANS products
for the three months ended March 31, 1997 to $3.14 million, an increase of
$700,000, or 28.3 percent, over the comparable 1996 period.

During the third quarter of 1996, the Company completed clinical validation of
the MPS system for cardioplegia delivery and began commercial shipments during
September 1996. Revenue from the MPS system and related disposable products
since that time have not met management's expectations. Clinical use of the MPS
since its introduction has validated that the MPS provides simpler, more
flexible and cost-effective management of myocardial protection. As a
consequence of the current hospital consolidation trend, coupled with the
intense pressure hospitals are under to minimize capital expenditures, however,
hospitals have been reluctant to make timely purchase decisions on new capital
equipment. Therefore, to accelerate adoption of MPS and shorten the selling
process, in March 1997, the Company began to offer MPS on a one-year rental
basis and on a lease/purchase basis. This strategy will not generate the level
of short-term revenues that sales would because the rental approach does not
qualify as a sale. In management's opinion, however, this strategy is more
likely to accelerate placement of MPS systems and generate related disposable
revenue. The Company believes that once a surgeon uses MPS, it will be very
difficult to return to old, make-shift systems. There can be no assurance, or
course, that the Company's rental strategy will accelerate placement of MPS
systems.

Net revenue from sales of the Company's other cardiovascular products, pressure
monitoring kits used in labor and delivery, and specialized fluid delivery
tubing sets, decreased from $3.70 million during the three months ended March
31, 1996 to $3.38 million for the same period during 1997, primarily due to
lower unit sales volume from the Company's specialized intravenous fluid
delivery tubing sets and pressure monitoring kits.


                                       12

<PAGE>   14

Gross Profit. Gross profit of $3.86 million for the three months ended March
31, 1997, was $365,000, or 10.4 percent above the level for the comparable 1996
period. As a percentage of net revenue, gross profit increased during the three
months ended March 31, 1997 to 57.9 percent as compared to 56.9 percent for the
comparable 1996 period. This increase in gross profit and gross profit margin
was attributable to the increased revenue generated by ANS, since ANS products
contribute higher gross profit margins than the Company's other product lines.

Operating Expenses. Research and development expense decreased to $605,000
during the three months ended March 31, 1997, compared to $896,000 for the same
period a year ago, and decreased as a percentage of net revenue from 14.6
percent in 1996 to 9.1 percent in 1997. This decrease in expense during 1997
compared to 1996 was the result of a reduction in salary and contract labor
expense from staffing reductions due to the completion of the development of
the MPS system. Management expects research and development expenditures to
approximate $2.2 million for the remainder of 1997 and expects about half of
such expenditures to be directed to refining current ANS products and
developing next generation ANS products for market introduction during 1998.
The other half of expenditures for the remainder of 1997 will be directed to
continued developments in the MPS system. Management expects that most of its
research and development activities during 1997 will continue to be financed
through internally generated funds.

Marketing, general and administrative expenses as a percentage of net revenue
increased to 42.7 percent for the three months ended March 31, 1997, compared
to 41.9 percent for the comparable period during 1996, and the dollar amount
increased by $269,000. The largest increase occurred in marketing expense with
expenditures in 1997 increasing by $247,000 over the comparable period a year
ago, and as a percentage of net revenue, increased to 24.9 percent in 1997
compared to 23.0 percent in 1996. Of such increase, $209,000 was additional
marketing expense of ANS related to additional salary, benefit, commission, and
consulting expense. During the first quarter of 1997, the Company continued
implementing ANS training, customer support, and sales and marketing materials
and videos. The Company has also reestablished relationships with key
implanters who had discontinued using the ANS products prior to the Company's
acquisition during March 1995. The remainder of the increase in marketing
expense of $62,000 in 1997 compared to 1996 was primarily the result of
additional promotional expense and convention expense directed toward sales
efforts of the MPS system. Currently, the Company has five direct salespersons
marketing the MPS system and does not anticipate adding additional salespersons
during the remainder of 1997. In early 1997, the Company decided to offer MPS
on a one-year rental basis and on a lease/purchase basis to accelerate the
adoption of MPS and shorten the selling process. If this strategy is
successful, management would reevaluate adding salespersons during 1997, as
circumstances warrant. Management expects to continue to focus its efforts for
MPS during the remainder of 1997 on the U.S. and Canadian markets, and does not
plan market introduction of the MPS internationally until fiscal 1998.

General and administrative expense as a percentage of net revenue decreased to
17.8 percent during the three months ended March 31, 1997 compared to 18.9
percent for the same period during 1996, while the dollar amount increased by
$22,000. This slight increase in expense during 1997 compared to 1996 was the
result of higher amortization expense of ANS intangibles.


                                       13

<PAGE>   15
Earnings From Operations. Earnings from operations increased to $412,000 during
the three months ended March 31, 1997 compared to $25,000 for the comparable
1996 period. This increase during 1997 compared to 1996 was the result of the
$365,000 increase in gross profit discussed above and an overall decrease of
$22,000 in operating expenses.

Other Expense. Other expense increased to $261,000 during the three months
ended March 31, 1997, compared to $101,000 for the comparable 1996 period as a
result of three factors. First, interest expense increased by $60,000 during
1997 compared to 1996. During the first quarter of 1997, the Company incurred
additional indebtedness of $4.45 million which was utilized to pay contingent
earn-out consideration and purchase certain patent rights from Neuromed's
former owner. See Note 4 of the Notes to Condensed Consolidated Financial
Statements. In addition, higher overall interest rates on borrowed money also
contributed to the increase in interest expense during 1997 compared to 1996.
Second, interest income decreased $54,000 during 1997, compared to 1996,
reflecting lower funds available for investment. Finally, the Company incurred
a net loss of $36,000 during the three months ended March 31, 1997 from the
sale of certain marketable security investments compared to net gains on the
sale of certain marketable security investments during the same period in 1996
of $10,000.

Income Taxes. The Company recorded income tax expense during the three months
ended March 31, 1997, of $57,000, an effective rate of 37.6 percent. The
Company's expense for amortization costs in excess of net assets acquired
(goodwill) is not deductible for tax purposes, thus explaining the higher
effective tax rate compared to the U.S. statutory rate for corporations of 34
percent. During the three months ended March 31, 1996, the Company recorded
income tax expense of $18,000, despite incurring a loss before income taxes of
$76,000, as a consequence of the nondeductibility of amortization expense of
costs in excess of net assets acquired.

Net Earnings (Loss). Net earnings increased to $94,000 during the three months
ended March 31, 1997 compared to a net loss of $95,000 during the same period a
year earlier. This increase during 1997 compared to 1996 was the result of the
increase in earnings from operations discussed above.

LIQUIDITY AND FINANCIAL POSITION

The Company's working capital decreased from $11.1 million at year-end 1996 to
$3.55 million at March 31, 1997, principally due to a reclassification of notes
payable from long-term to short-term. The ratio of current assets to current
liabilities was 1.3:1 at March 31, 1997, compared to 3.0:1 at December 31,
1996.

Inventories decreased slightly to $8.32 million at March 31, 1997, compared to
the December 31, 1996 level of $8.36 million. The Company anticipates a
decrease in its investment in inventories of approximately $1.0 million by
year-end 1997 from the year-end 1996 level.

During the three months ended March 31, 1997, the Company invested $128,000 in
capital expenditures for additional manufacturing tooling and equipment. The
Company expects to incur approximately $1.3 million of additional capital
expenditures during the remainder of fiscal 1997, principally for manufacturing
tooling and equipment for the Company's current ANS SCS products and next
generation neuromodulation products.

In connection with the Neuromed acquisition in March 1995, the Company agreed
to pay contingent earn-out consideration in January 1996 and January 1997,
depending on Neuromed's attainment of certain sales objectives. At year-end
1995, the Company had a note payable in connection with the 1995 earn-out
consideration in the amount of $1.5 million, payable in January 1996. The
Company withheld payment of the $1.5 million obligation pending arbitration of
certain disputes between the Company and Neuromed's former owner. In October
1996, the sales objectives for the 1996 earn-out were reached and the Company
recorded a note payable in the amount of $3.37 million which was due and
payable in January 1997. The Company similarly withheld payment of this note
pending arbitration. In addition, the Company had a short-term note payable to
the former owner of Neuromed at December 31, 1996, in the amount of $972,000
due in January 1997, related to certain purchase price adjustments (principally
tax refunds and future tax credits) awarded through an arbitration. The Company
paid the $972,000 obligation during January 1997 utilizing a portion of its
cash reserves. On February 6, 1997, the Company and the former owner of
Neuromed reached a settlement (the "Settlement") of all issues between them.
Under terms of the Settlement, the Company agreed to pay $3.0 million in cash
on March 3, 1997, to purchase certain patent rights from Neuromed's former
owner and $500,000 in cash and $1.0 million in a promissory note payable on
February 6, 1998, for full settlement of the contingent earn-out
considerations. The promissory note bears interest at the rate of 10 percent
per annum with interest due and payable monthly. On March 3, 1997, the Company
made payment of the $3.5 million in cash pursuant to the Settlement with
borrowed funds discussed below. See Note 4 of the Notes to Condensed
Consolidated Financial Statements.

On February 21, 1997, the Company borrowed $2.0 million from a shareholder
pursuant to a promissory note. The promissory note is due and payable on
February 21, 1998, and bears interest at the rate of 6 percent per annum. In
addition, the Company issued the shareholder five-year warrants to purchase
100,000 shares of common stock at an exercise price of $6.50 per share, the
closing sales price on the date the indebtedness was incurred. The Company
utilized proceeds from the loan to pay a portion of the Settlement discussed
above. See Note 4 of the Notes to Condensed Consolidated Financial Statements.

On March 3, 1997, the Company amended its $5.0 million working capital line of
credit and $15 million acquisition line of credit with NationsBank of Texas,
N.A. Under the third amended agreement, the working capital line of credit was
increased to $5.65 million and a $350,000 term loan facility replaced the
acquisition line of credit. Both facilities expire on January 31, 1998.
Borrowings under the working capital line of credit bear interest at prime plus
100 basis points, or at the Company's option, LIBOR plus 275 basis points.
Borrowings under the term loan facility bear interest at prime plus 100 basis
points, or at the Company's option, LIBOR plus 225 basis points. The facilities
are collateralized by all of the Company's assets with the exception of the
real property, building, and equipment that collateralize the long-term
financing on the Company's facility in Allen, Texas. Under the working capital
line, the Company is required to make monthly principal payments of $90,000,
with interest payable quarterly. Under the term loan facility, no principal
payments are due until maturity and interest is payable quarterly. On March 3,
1997, the Company increased its borrowings under the working capital line of
credit by $1.1 million and borrowed $350,000 under the term loan facility.
These additional borrowings were utilized to pay a portion of the debt under
the Settlement described above. See Note 4 of the Notes to Condensed 
Consolidated Financial Statements.

Management believes that its current cash, cash equivalents and marketable
securities and funds generated from operations will be sufficient to satisfy
normal cash operating requirements, debt service and capital requirements
during the remainder of 1997. During the first quarter of 1998, however, $8.1
million of debt will become due and payable. The Company is exploring various
means to either refinance or payoff the debt entirely, including without
limitation, a new loan facility, alternative debt or equity financing, asset or
division sale, technology transfer or other arrangements.

CASH FLOWS

Net cash provided by operating activities decreased to $483,000 during the
three months ended March 31, 1997, from $645,000 for the same period a year ago
primarily due to a reduction in the level of accounts payable by $1,004,000 in
the 1997 period.

Net cash provided by investing activities increased to $288,000 during the
three months ended March 31, 1997, compared to a net use of cash during 1996 of
$833,000. This increase resulted from two factors. First, the Company reduced
its use of cash for capital expenditures from $413,000 during 1996 to $128,000
during 1997, a decrease of $285,000. Second, the Company during the 1997 period
was a net seller of marketable securities which provided cash of $416,000 while
in the 1996 period, the Company was a net purchaser of marketable securities
which used cash of $420,000.

Net cash used in financing activities for the three months ended March 31,
1997, was $936,000 while financing activities during the same period in 1996
provided net cash of $459,000. This decrease was primarily due to the use of
$1,286,000 in 1997 to reduce debt under short-term and long-term notes payable.

RECENT EVENTS

On March 10, 1997, the Company announced that the Company's Board of Directors
had engaged Smith Barney and Rauscher Pierce Refsnes to seek strategic
alternatives to enhance shareholder value. These strategic alternatives may
include a merger, sale of assets, other business combination, or a joint
venture or strategic alliance.

FORWARD-LOOKING STATEMENTS

The following is a "safe harbor" statement under the Private Securities
Litigation Reform Act of 1995:  Other than historical information, the matters
discussed in this Management's Discussion and Analysis of Financial Condition
and Results of Operations are forward-looking statements that are based on
management assumptions and involve risks and uncertainties, including but not
limited to the Company's ability to develop, clinically validate, and gain
market acceptance for new products, including the MPS system, new generation
ANS products, and other products; continued growth in ANS revenues;
accelerating the adoption of MPS systems and  the related disposables utilizing
one-year rental agreements; successfully developing the infrastructure at ANS
to enable the Company to grow the business into a solid player in the SCS
market; government regulation; competition and technological changes that may
render the Company's products obsolete or noncompetitive; general domestic and
international economic conditions; and other risks detailed from time to time in
the Company's SEC public filings. Consequently, if such management assumptions
prove to be incorrect or such risks or 


                                       16

uncertainties materialize, the Company's actual results could differ materially
from the results forecasted in the forward-looking statements.            

CURRENCY FLUCTUATIONS

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