                           ZILA, INC. AND SUBSIDIARIES
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.       In the opinion of management of Zila, Inc. and Subsidiaries ("Zila" or
         the "Company"), all adjustments, consisting of normal recurring
         accruals, considered necessary for a fair presentation have been
         included in the condensed consolidated financial statements. The
         results of operations for the interim period are not necessarily
         indicative of the results that may be expected for the entire year. 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 those estimates.

         The condensed consolidated financial statements include the accounts of
         Zila, Inc. and its wholly-owned subsidiaries, Zila Pharmaceuticals,
         Inc., Zila International Inc., Zila Ltd., Bio-Dental Technologies
         Corporation ("Bio-Dental"), Cygnus Imaging, Inc. ("Cygnus"), and Oxycal
         Laboratories, Inc. ("Oxycal"). All significant intercompany balances
         and transactions are eliminated in consolidation.

2.       On November 5, 1997, the Company's Zila Pharmaceuticals, Inc.
         subsidiary completed its acquisition of the Peridex(R) product line
         ("Peridex"), a prescription anti-bacterial oral rinse from The Procter
         & Gamble Company ("P&G"). The purchase price was $12,000,000 plus the
         value of acquired inventory. Payment of the purchase price was
         structured as follows: $6,000,000 paid at closing, $1,000,000 payable
         within 30 days after closing, $3,000,000 payable within 180 days after
         closing, $1,000,000 is payable within 12 months after closing, and
         $1,000,000 is payable within 24 months after closing.

         On November 10, 1997, the Company acquired, by merger, Oxycal
         Laboratories, Incorporated ("Oxycal"). Oxycal develops, manufactures
         and markets a patented, enhanced form of Vitamin C under the trademark
         Ester-C(R). The Company paid $28,000,000 for all outstanding shares of
         Oxycal. The Company raised the funds to consummate the Merger in a
         private placement of 30,000 shares of the Company's Series A
         Convertible Redeemable Preferred Stock ("Preferred Stock") and warrants
         to purchase 360,000 shares of the Company's Common Stock for
         $30,000,000.

         The Preferred Stock is convertible into shares of the Company's common
         stock at a conversion rate based on the price of such common stock at
         the date of issuance. However, if the market price of the Company's
         common stock does not appreciate by a fixed percentage at various
         measurement dates, the holders of the Preferred Stock have the right to
         receive additional shares of the Company's 


                                       7
<PAGE>   8
         common stock upon conversion, based on a repricing formula. Per
         guidance from the Securities and Exchange Commission, the intrinsic
         value of the beneficial conversion feature of the Preferred Stock has
         been measured and recognized as an embedded dividend and such non-cash
         embedded dividend has been deducted from net income in the accompanying
         condensed consolidated statement of operations to arrive at the amount
         of net loss available to common shareholders. Additionally, because
         the Preferred Stock has conditions for redemption that are not solely
         within the control of the Company, it has been classified outside of
         permanent equity in the accompanying condensed consolidated balance
         sheet and is being accreted to its redemption value.

         The Peridex and Oxycal acquisitions were accounted for using the
         purchase method of accounting for business combinations. In connection
         with the Oxycal acquisition, the Company has not yet completed the
         process of allocating the excess of assets acquired over liabilities
         assumed to specific assets and liabilities, but believes that this
         excess will relate principally to goodwill, which will be amortized
         over 20 years. In connection with the Peridex acquisition, the excess
         has been allocated to goodwill and is being amortized over 12 years.
         Results of operations of Peridex and Oxycal have been included in the
         Company's statement of operations from their respective acquisition
         dates.

         The following pro forma summary presents the consolidated results of
         operations as if the acquisitions had occurred as of the beginning of
         each period presented and do not purport to be indicative of what would
         have occurred had the acquisitions been made as of those dates or of
         results which may occur in the future. The pro forma summary data for
         the six months ended January 31, 1997 combines historical financial
         information of the Company for the six months ended January 31, 1997
         and Peridex and Oxycal for the six months ended December 31, 1996. The
         pro forma summary data for the six months ended January 31, 1998
         combines actual financial results of the Company for the six months
         ended January 31, 1998, which includes Peridex and Oxycal results for
         the three months ended January 31, 1998, and Peridex and Oxycal for the
         three months ended September 30, 1997. The embedded dividend for the
         six months ended January 31, 1998 and 1997 represents 180 days of
         accretion and is based on the assumption that the Preferred Stock had
         been issued at the beginning of each period.

3.       The Company has scheduled a special meeting of its shareholders on
         April 14, 1998, seeking ratification of the sale of the Series A
         Preferred Stock in accordance with the terms of the securities purchase
         agreement relating to the sale of the Preferred Stock which requires,
         at the request of the holders of the Preferred Stock, the Company to
         hold a special meeting in the event the average market price of the
         Company's Common Stock drops below $6.50 per share. The shareholders
         will be asked to ratify the terms of the sale of the Preferred Stock
         and, in the event a majority of the Company's shareholders do not vote
         in favor of such proposal, the holders of the Preferred Stock could
         (depending on the price of the common stock on the date of conversion)
         be limited in their ability to fully convert their shares of Preferred
         Stock into Common Stock of the Company. The securities purchase
         agreement relating to the sale of the Preferred Stock provides that if
         the holders of the Preferred Stock are unable to fully convert their
         shares, they have the right to require the Company to repurchase those
         shares of Preferred Stock that cannot be converted. If the Company is
         required to repurchase a significant percentage of the Preferred Stock,
         such repurchase could have a significant adverse impact on the Company
         depending on the price of the Common Stock on the date of repurchase.


4.       In March 1997, the Financial Accounting Standard Board ("FASB") issued
         Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings
         Per Share", which is effective for financial statements for both
         interim and annual periods ending after December 15, 1997. The Company
         has implemented this Statement and, as required, has restated earnings
         per share ("EPS") for all periods presented. This new standard requires
         dual presentation of "basic" and "diluted" EPS on the face of the
         statement of operations and requires a reconciliation of the numerator
         and denominator of basic and diluted EPS calculations. Basic earnings
         per common share is computed on the weighted average number of shares
         of common stock outstanding during each period. Diluted earnings per
         common share is computed on the weighted average number of shares of
         common stock outstanding plus additional shares that would have been
         outstanding if all dilutive potential common shares had been issued.
         The Company's loss per common share is computed by taking the net
         income for the quarter and six months ended January 31, 1998 and
         deducting the Series A Preferred Stock embedded dividend and dividing
         the sum of these amounts by the weighted average number of shares
         outstanding during each period.

         Options and warrants to purchase shares of common stock at various
         prices were outstanding during the quarter and six months ended January
         31, 1998 and 1997 but were not included in the computation of diluted
         earnings per share because their effect would be antidilutive. In
         addition, the incremental shares 



                                       9
<PAGE>   10
         from assumed conversion of Series A Convertible Preferred Stock to
         shares of common stock were not included in the computation of diluted
         earnings per share for the quarter and six months ended January 31,
         1998 because their effect would also be antidilutive.



5.        Inventories consist of the following:

6.       The Company has a New Drug Application pending with the Food and Drug
         Administration ("FDA") for ORATEST. The initiation of the marketing of
         ORATEST in the United States is dependent upon the approval of the New
         Drug Application by the FDA. During 1994, the FDA approved the
         Company's application for an Investigational New Drug for ORATEST,
         which allows the Company to manufacture the product in the United
         States for clinical studies and export to certain foreign countries.
         The Company believes that the FDA will approve the New Drug Application
         and the production and marketing of ORATEST.

7.       In July 1995, Bio-Dental was named as a defendant, along with
         Bio-Dental's transfer agent and a shareholder of Bio-Dental
         ("Shareholder"), in a lawsuit. The lawsuit alleges that Bio-Dental
         wrongfully failed to register 200,000 Bio-Dental shares in the name of
         the plaintiffs which were pledged as security by the Shareholder for a
         debt owed by the Shareholder to the plaintiffs.

         Bio-Dental denied all of the material allegations of the lawsuit
         against it and has asserted various affirmative defenses. Bio-Dental
         will continue to vigorously defend against the claims set forth in the
         lawsuit. In September 1996, Bio-Dental accrued a liability of $450,000
         because it decided to attempt a settlement of this litigation.
         Bio-Dental's attempt was not successful. In January 1997, a judgement
         by the court in favor of Bio-Dental and against the plaintiffs was
         filed. In February 1997, the plaintiffs started the process to appeal
         the judgement.

         Upon consummation of the Company's merger with Bio-Dental, each of the
         outstanding shares of Bio-Dental common stock was converted into .825
         shares of the Company's common stock. Subsequent to the merger, the
         Company's stock transfer agent was presented with a certificate
         purporting to represent 220,000 shares of Bio-Dental common stock which
         did not appear on the records of Bio-Dental's stock transfer agent as
         of the closing date. The Company is 


                                       10
<PAGE>   11
         currently investigating this matter and has not determined whether any
         shares of the Company's common stock are required to be issued in
         exchange for the shares purportedly represented by this certificate.

         The Company occasionally encounters minor litigation as a means to
         resolve disputes, which arise in the ordinary course of business. None
         of these minor lawsuits are believed to be material to the Company's
         ongoing operations or operating results.


8.       Under the Company's Equity Line Agreement with Deere Park Capital
         Management (the "Investor"), the Company is allowed to sell up to $25
         million of its common stock. The Company was committed to sell $10
         million of its common stock to the Investor over the commitment period
         and fulfilled this commitment with the sale of $2,000,000 of the
         Company's common stock in January 1998. The proceeds are to be used for
         general corporate purposes.

9.       Deferred income taxes reflect the tax effect of temporary differences
         between the amounts of assets and liabilities recognized for finacial
         reporting and tax purposes. In the past, the Company had fully offset
         its net deferred tax asset with a valuation allowance due to the
         Company's lack of earnings history. For the quarter ended January 31,
         1998, the Company returned to profitability and as a result recorded an
         income tax benefit of $1,000,000 ($300,000 of which was attributable to
         the exercise of common stock options and therefore was credited to
         capital in excess of par value).

10.      In June 1997, the FASB issued SFAS No. 130, Reporting Comprehensive
         Income, and SFAS No. 131, Disclosures about Segments of an Enterprise
         and Related Information. SFAS No. 130 requires that an enterprise (a)
         classify items of other comprehensive income by their nature in a
         financial statement and (b) display the accumulated balance of other
         comprehensive income separately from retained earnings and additional
         capital in the equity section of a statement of financial position.
         SFAS No. 131 established standards for the way that public enterprises
         report information about operating segments in annual financial
         statements and requires that those enterprises report selected
         information about operating segments in interim financial reports to
         shareholders. It also establishes standards for disclosures about
         products and services, geographic areas and major customers. Both
         statements are effective for fiscal years beginning after December 15,
         1997. The Company has not completed evaluating the impact of
         implementing the provisions of SFAS Nos. 130 and 131.

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

                           ZILA, INC. AND SUBSIDIARIES

RESULTS OF OPERATIONS:

                  For the quarter ended January 31, 1998, the Company had net
income of $1,281,999 compared to a net loss of $1,455,619 for the quarter ended
January 31, 1997. For the six month period ended January 31, 1998, the Company
had net income of $852,209 compared to a net loss of $3,727,141 for the six
month period ended January 31, 1997.

                  Additionally, as a result of the embedded dividend on the
Series A Preferred Stock issued in November 1997, net income available to common
shareholders has been reduced by the $3,154,692 accretion of such dividend
during the quarter and six months ended January 31, 1998. Therefore, for the
quarter and six months ended January 31, 1998, when taking into account the
embedded dividend, the Company had a net loss available to common shareholders
of $1,872,693 and $2,302,483, respectively.

                  Revenues during the second quarter of the current fiscal year
totaled $16,940,983 compared to revenues of $9,779,214 during the second quarter
of the prior fiscal year, a 73.2% increase. For the first six months of this
fiscal year, revenues were $27,741,165 compared to $19,009,737 for the same
period of the prior fiscal year, a 45.9% increase. The growth in revenues was
primarily attributable to the Company's acquisitions of Oxycal and Peridex.
Additional growth in revenues during the quarter and six months ended January
31, 1998 was attributable to the Company's Zilactin family of products, software
and dental supply sales.

                  Cost of products sold as a percentage of revenues decreased to
47.9% in the quarter ended January 31, 1998 from 62.0% in the quarter ended
January 31, 1997 and to 53.0% from 62.0% for the six month periods in 1998 and
1997, respectively. These decreases are primarily due to lower costs resulting
from the acquisitions of Oxycal and the Peridex(R) product line.

                  Selling, general and administrative expenses increased
$2,587,160 from $4,534,207 in the second quarter of fiscal year 1997 to
$7,121,367 for the same period in fiscal year 1998 and increased $2,711,928 from
8,696,367 during the six months of fiscal 1997 to $11,408,295 during the six
months of fiscal 1998. These increases are attributable mainly to selling,
general and administrative expenses resulting from the Oxycal acquisition.
Additional expenses were incurred related to regulatory, pre-marketing and
clinical activities associated with the Company's OraTest oral cancer detection
system.


                                       12
<PAGE>   13
         
                  Depreciation and amortization expenses increased $671,657 from
$245,969 in the second quarter of fiscal 1997 to $917,626 for the same period in
fiscal year 1998 and increased $722,438 from $528,170 during the six months of
fiscal 1997 to $1,250,608 during the six months of fiscal 1998. The increases
are mainly due to the additional amortization of goodwill from the Oxycal and
Peridex acquisitions which occurred during the second quarter of fiscal 1998 and
the Cygnus acquisition which occurred during the third quarter of fiscal 1997.

                  Merger related expenses decreased $20,313 from $178,730 in the
second quarter of the prior fiscal year to $158,417 in the second quarter of the
1998 fiscal year. For the six months ended January 31, 1998, merger related
expenses decreased to $230,632 from $328,555 from the same period last year.
Merger related expenses during the first six months of fiscal 1997 related to
the acquisition of Bio-Dental, whereas the expenses incurred during the first
six months of fiscal 1998 relate to the acquisitions of Oxycal and the
Peridex(R) product line.

                  Impairment charges during the first six months of fiscal year
1997 of $587,659 related to an impairment loss recognized to reduce the carrying
value of certain Bio-Dental long-lived assets including goodwill and software
rights.

                  Litigation expenses of $227,500 for the quarter and $1,060,251
for the six months ended January 31, 1997, related to legal expenses arising out
of the Company's efforts to prevent infringements on the Zilactin patents and an
accrual of a liability based on the Company's attempted settlement of the
litigation described in Note 7 to the financial statements (See "Part II - Other
Information Item 1 - Legal Proceedings").

                  In the past, the Company had fully offset its net deferred tax
asset with a valuation allowance due to the Company's lack of earnings history.
For the quarter ended January 31, 1998, the Company returned to profitability
and as a result recorded an income tax benefit of $1,000,000 ($300,000 of which
was attributable to the exercise of common stock options and therefore was
credited to capital in excess of par value).

LIQUIDITY AND CAPITAL RESOURCES

                  At January 31, 1998, the Company had net working capital of
$16,530,170 and its current ratio was 2.5 to 1, an increase from the $4,974,084
of net working capital and 1.9 to 1 current ratio at July 31, 1997.

                  Trade accounts receivable, net of allowance for uncollectible
accounts at January 31, 1998 were $5,448,299 compared to net receivables at July
31, 1997 of $2,822,687. Trade accounts receivable as a percentage of quarterly
net sales of $16,839,471 were 32.4% at January 31, 1998 as compared to 29.1% at
July 31, 1997 which had quarterly net sales of $9,712,162.


                                       13
<PAGE>   14
                  At January 31, 1998, the Company had inventories of
$9,597,885, an increase of $5,311,258 from inventories at July 31, 1997. The
increase is mainly due to inventories acquired in the Oxycal and Peridex
acquisitions. The Company will need to build up inventories of Peridex over the
last six months of fiscal 1998 to prepare for a short-term stoppage in
production due to a change in contract manufacturers of Peridex. The Company
believes current inventories, other than Peridex, are at levels necessary to
support market expansion and to maintain adequate liquidity.

                  Operating cash flows for the six months ended January 31, 1998
increased when compared to the six month period ended January 31, 1997,
primarily as the result of the Company's net income in the current fiscal period
versus a net loss in the prior comparative period, offset in part by the
differences in the net changes in working capital items in each period.

                  Management believes that continued growth in the Company's
sales of its products will provide sufficient funding for the Company's current
operations for the next twelve months. The Company may require additional
financing to fund future OraTest manufacturing and marketing costs, Peridex
contractual obligation payments and the buildup of Peridex inventories. The
Company's Equity Line Agreement (the "Investment Agreement") with Deere Park
Capital Management allows the Company to raise a total of $25 million through
the sale of its common stock. As of January 31, 1998, the Company has raised $13
million under the Investment Agreement.

                  The Company has not completed its evaluation of the impact the
Year 2000 computer problem may have on its business. However, the Company does
not expect the costs to address the problem to be material and it does not
expect the consequences of incomplete or untimely resolution of the problem to
materially impact the operation of its business.

PART II - OTHER INFORMATION

Item 1.- Legal Proceedings

         Wildwood. In July 1995, Bio-Dental was named as a defendant, along with
Bio-Dental's transfer agent and a shareholder of Bio-Dental ("Shareholder"), in
a lawsuit. The lawsuit alleges that Bio-Dental wrongfully failed to register
200,000 Bio-Dental shares in the name of the plaintiffs which were pledged as
security by the Shareholder for a debt owed by the Shareholder to the
plaintiffs.

         Bio-Dental denied all of the material allegations of the lawsuit
against it and has asserted various affirmative defenses. Bio-Dental will
continue to vigorously defend against the claims set forth in the lawsuit. In
September 1996, Bio-Dental accrued a liability of $450,000 because it decided to
attempt a settlement of this litigation. Bio-Dental's attempt was not
successful. In January 1997, a judgement by the court in favor of Bio-Dental and
against the plaintiffs was filed. In February 1997, the plaintiffs started the
process to appeal the judgement.

         The Company occasionally encounters minor litigation as a means to
resolve disputes, which arise in the ordinary course of business. None of these
minor lawsuits are believed to be material to the Company's ongoing operations
or operating results.


Item 4 - Submission of matters to a vote of security holders.

         (a)      The Company held its Annual Meeting on December 11, 1997.
