                           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 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"), and Cygnus Imaging, Inc. ("Cygnus").  All significant
      intercompany balances and transactions are eliminated in consolidation.

2.    On January 8, 1997, the Company's merger with Bio-Dental was completed. On
      December 30, 1996, Bio-Dental's shareholders approved the all-stock
      transaction which provided for a per share exchange of .825 shares of the
      Company's common stock for each share of Bio-Dental common stock
      outstanding.

      The Bio-Dental merger has been accounted for as a pooling-of-interests,
      and accordingly, the condensed consolidated financial statements give
      retroactive effect to the Bio-Dental merger and include the combined
      operations of Zila and Bio-Dental for all periods presented. Certain
      adjustments and reclassifications have been made to conform previously
      issued Bio-Dental financial statements to classifications and accounting
      policies used by Zila.

3.    Net loss per common share is computed based on the weighted average number
      of shares outstanding during each period after giving effect to any
      dilutive stock options and warrants which are considered to be common
      stock equivalents. For the quarters and nine month periods ended April 30,
      1997 and 1996, options and warrants that would otherwise qualify as common
      stock equivalents are excluded since their inclusion would have the effect
      of decreasing the loss per share.

5.    On June 1, 1997, the Company's revolving bank line of credit which was
      collateralized by trade accounts receivable, inventories and rights to
      payment expired. At July 31, 1996 and April 30, 1997, the Company had $0
      and $260,000 in borrowings against this line of credit, respectively.
      Included in short-term borrowings at April 30, 1997 is $85,784 for
      installments due on the Company's directors and officers liability
      insurance, product liability insurance, and installments due on an
      equipment loan.


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.    The Company adopted Statement of Financial Accounting Standards ("SFAS")
      No. 121, Accounting for Impairment of Long-Lived Assets and for Long-Lived
      Assets to Be Disposed Of, on August 1, 1996. As a result of this analysis,
      the Company determined that the long-lived assets associated with
      Integrated Dental Technologies ("IDT"), a wholly owned subsidiary of
      Bio-Dental, would not likely be recoverable, as defined by SFAS No. 121.
      As a result, a $587,659 impairment loss was recognized to reduce the
      carrying value of these long-lived assets.


8.    In October 1995, the Financial Accounting Standards Board issued SFAS No.
      123 "Accounting for Stock-Based Compensation" which became effective for
      the Company beginning August 1, 1996. SFAS No. 123 requires expanded
      disclosures of stock-based compensation arrangements with employees and
      encourages (but does not require) compensation cost to be measured based
      on the fair value of the equity instrument awarded. Companies are
      permitted, however, to continue to apply APB Opinion No. 25, which
      recognizes compensation cost based on the intrinsic value of the equity
      instrument awarded. The Company has elected to continue to apply APB
      Opinion No. 25 in its


                                       8
<PAGE>   9
      financial statements and will disclose the pro forma effect on net income
      and earnings per share, as if the Company had applied the new Statement in
      its year-end financial statements.

9.    a) On April 13, 1994, the Company filed a complaint in the United States
      District Court for the District of Arizona, titled Zila Pharmaceuticals,
      Inc. v. Colgate-Palmolive Company ("Colgate"). The complaint alleged that
      Colgate's Orabase Gel product infringes the Company's U.S. Patent No.
      5,081,158 (the "'158 Patent"), which covers the Company's
      non-prescription, film-forming, bioadhesive medications. The complaint
      sought to enjoin Colgate's manufacture and distribution of Orabase Gel and
      requested an award of damages in an appropriate amount. The case was
      settled on March 6, 1997 and had no material impact on the Company's
      financial statements.

      b) 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. In November 1996,
      Bio-Dental was granted a summary judgment in which the court ruled in
      favor of Bio-Dental. The plaintiffs filed a motion to reconsider the
      summary judgment ruling, which was denied by the court in January 1997.
      Having lost the summary judgment ruling and later having this ruling
      upheld, the plaintiffs are in the process of filing an appeal. Bio-Dental
      will continue to vigorously defend against the claims set forth in the
      lawsuit; however, a contingent liability has been accrued to cover
      probable losses.

      c) 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 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.

10.   On April 4, 1997, the Company acquired Cygnus Imaging, Inc., a small
      privately held company located in Scottsdale, Arizona that manufactures
      and distributes intra-oral camera systems and other dental imaging
      products. The acquisition was accounted for as a purchase and resulted in
      the issuance of approximately 260,000 shares of Zila common stock and the
      recording of approximately $2,059,000 of goodwill. The Company is still
      evaluating certain contingencies that could impact the allocation of the
      purchase price.


                                       9
<PAGE>   10
11.   Effective April 30, 1997, Zila entered into an investment agreement (the
      "Investment Agreement") with Deere Park Capital Management (the
      "Investor") which allows the Company to sell up to $25 million of Zila's
      common stock with the proceeds to be used to fund OraTest marketing and
      general corporate purposes. The option to sell stock to the Investor will
      remain available for a period of twelve months following the effective
      date of the registration statement discussed below (the "Twelve Month
      Period"). As part of the Investment Agreement, Zila sold $3.0 million of
      stock on April 30, 1997, and has committed to sell an additional $10
      million of common stock to the Investor over the Twelve Month Period. At
      April 30, 1997, the net proceeds of $2.9 million from the initial sale of
      shares were held in escrow. During May 1997, the cash held in escrow was
      released to the Company.

      The Investment Agreement provides that Zila can obtain up to $2 million at
      any one time through the sale of the Company's common stock. All shares
      sold will be at a 7% discount to the average low trading price of the
      Company's common stock over a specified period of time, subject to a
      maximum purchase price calculation. Sales are subject to the satisfaction
      of certain conditions, including registration of the shares, a minimum
      market volume, and certain limitations on the number of shares of the
      Company's common stock outstanding.

      As a commitment fee for keeping the equity line available for the Twelve
      Month Period, the Company has issued warrants dated May 7, 1997 (the
      "Warrants") to the Investor exercisable for 300,000 shares of common stock
      at an exercise price of $8.6125 per share. The Warrants are exercisable
      for a three-year period commencing October 31, 1997. A registration
      statement pertaining to the shares issued and to be issued under the
      Investment Agreement and the warrants is to be filed and effective no
      later than August 30, 1997 before any funds, other than the initial draw
      of $2.9 million, are drawn under the Investment Agreement.

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


ZILA, INC. AND SUBSIDIARIES

MERGER WITH BIO-DENTAL:

      On January 8, 1997, the Company's merger with Bio-Dental was completed. On
December 30, 1996, Bio-Dental's shareholders approved the all-stock transaction
which provided for a per share exchange of .825 shares of the Company's common
stock for each share of Bio-Dental common stock outstanding.

      The Bio-Dental merger has been accounted for as a pooling-of-interests,
and accordingly, the condensed consolidated financial statements give
retroactive effect to the Bio-Dental merger and include the combined operations
of Zila and Bio-Dental for all periods presented. Certain adjustments and
reclassifications have been made to conform previously issued Bio-Dental
financial statements to classifications and accounting policies used by Zila.

RESULTS OF OPERATIONS:

      For the quarter ended April 30, 1997, the Company had a net loss of
$1,447,087 compared to a net loss of $492,364 for the quarter ended April 30,
1996. For the nine month period ended April 30, 1997, the Company had a net loss
of $5,174,228 compared to a net loss of $1,604,248 for the nine month period
ended April 30, 1996.

      Net sales during the third quarter of the current fiscal year totaled
$9,912,648 compared to net sales of $9,143,739 during the third quarter of the
prior fiscal year, an 8.4% increase. For the first nine months of this fiscal
year, net sales were $28,880,090 compared to $28,435,990 for the same period of
the prior fiscal year, a 1.6% increase. The increases for both the quarter and
nine months ended April 30, 1997, were primarily the result of increased sales
of products in the Zila Pharmaceuticals' line, as well as increased sales at The
Supply House, a subsidiary of Bio-Dental, offset by decreased sales in certain
discontinued product lines associated with the restructuring of Bio-Dental's IDT
subsidiary, which occurred in prior periods.

      Cost of sales as a percentage of net sales decreased from 75.1% in the
quarter ended April 30, 1996 to 61.2% in the quarter ended April 30, 1997 and
from 66.3% to 61.8% for the nine month periods in 1996 and 1997, respectively.
The decreases for the quarter and nine months ended April 30, 1997 were
primarily due to the lower costs resulting from the restructuring of IDT.

      Licensing fees and royalty revenues were $15,345 for the quarter ended
April 30, 1997 compared to $1,005,488 for the quarter ended April 30, 1996. For
the nine month period ended April 30, 1997, licensing fees and royalty revenues
were $57,640 compared to $1,811,264 for the same period of the prior fiscal
year. Approximately $278,000 for the quarter and $977,000 for the nine months
ended April 30, 1996 were due to royalty revenues earned in fiscal 1996, related
to the licensing agreement between Bio-Dental and Denticator International, Inc.
("DII"). In July 1996, Bio-Dental disposed of its rights to receive future
royalty payments from DII in exchange for a lump sum payment of approximately
$7,500,000. In addition, amounts were recorded in fiscal 1996 attributable to
the licensing of OraTest for markets in the United Kingdom and the United States
by the Stafford-Miller Company and The Procter & Gamble Company, respectively.
Of these amounts, $625,000 was paid by Procter & Gamble as a one-time licensing
fee required in connection with the termination of its license agreement with
the Company.

      Selling, general and administrative expenses increased $309,183 from
$4,892,970 for the third quarter of fiscal year 1996 to $5,202,153 for the same
period in fiscal year 1997 and increased $736,959 from $13,689,731 during the
nine months of fiscal 1996 to $14,426,690 during the nine months of fiscal 1997.
Approximately $318,000 of the increase for the quarter ended April 30, 1997 was
attributable to costs associated with the funding of ORATEST research,
marketing, and start-up manufacturing costs. An additional $70,000, was expensed
during the quarter ended April 30, 1997 for shareholder relations and public
relations as compared to the same quarter of the previous year. Additionally,
the Company incurred approximately $109,000 in amortization costs related to the
purchased technology rights during the quarter ended April 30, 1997.

      For the nine months ended April 30, 1997, approximately $923,000 of the
increases were attributable to costs associated with the funding of ORATEST
research, start-up manufacturing costs and staffing. The Company also incurred
approximately $327,000 in amortization costs related to the purchased technology
rights during the nine months ended April 30, 1997. The increases for the
quarter and nine months ended April 30, 1997, were partially offset by decreases
in marketing, selling, product development and administrative expenses at
Bio-Dental resulting from the restructuring of IDT, which occurred in prior
periods.

      Merger related expenses of $38,311 for the quarter and $366,866 for the
nine months ended April 30, 1997, are directly related to the Bio-Dental merger.
Impairment charges of $587,659 for the nine months ended April 30, 1997, relate
to an impairment loss recognized to reduce the carrying value of IDT's
long-lived assets which included goodwill and software rights.

      Litigation costs, related to the Colgate and the Shareholder suits, during
the third quarter of fiscal year 1997 increased $73,087 from $10,950 in the
third quarter of fiscal year 1996 to $84,037 during the same period of fiscal
year 1997. For the nine months ended April 30, 1997, litigation costs increased
$878,967 to $1,144,288 from the same period last year. These increases were due
to the accrual of a contingent liability in the event that the outcome of the
Shareholder litigation would be unfavorable to Bio-Dental and also due to legal
expenses arising out of the Company's efforts to prevent infringements of the
Zilactin patents (See "Part II - Other Information Item 1 - Legal Proceedings")


                                       12
<PAGE>   13
      Restructuring charges for the nine months ended April 30, 1996, are
directly attributable to the restructuring of IDT.

      Interest income during the third quarter of fiscal year 1997 increased
$24,313 from $12,780 in the third quarter of fiscal year 1996 to $37,093 during
the same period in fiscal 1997. For the nine months ended April 30, 1997,
interest income increased $55,377 to $157,092 from the same period last year.
Interest expense decreased from $39,694 in the third quarter of the 1996 fiscal
year to $22,112 in the third quarter of 1997 and from $160,782 to $65,499 for
the nine month periods in 1996 and 1997, respectively. The decreases were
attributable to lower debt obligations during the first nine months of fiscal
year 1997 as compared to fiscal year 1996.



LIQUIDITY AND CAPITAL RESOURCES

      At July 31, 1996, the Company had net working capital of $6,579,463 and a
current ratio of 2.0 to 1. At April 30, 1997, the Company had net working
capital of $6,117,929 and a current ratio of 2.1 to 1.

      Accounts receivable at April 30, 1997 were $2,840,070 compared to accounts
receivable at July 31, 1996 of $2,821,440. Accounts receivable as a percentage
of quarterly net sales were 28.7% at April 30, 1997 compared to 30.9% at July
31, 1996. There continues to be an emphasis on strong credit management.

      At April 30, 1997, the Company had inventories of $3,651,752, a decrease
of $548,690 from inventories at July 31, 1996. The decrease was primarily due to
the planned reduction of IDT inventory and lower inventory at The Supply House
due to greater than anticipated April sales offset by an increase in inventory
levels at Zila Pharmaceuticals due to market expansion of its Zilactin family
line of products. The Company believes current inventories are at levels
necessary to support market expansion and to maintain adequate liquidity.

      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
support the production of its products in quantities sufficient to support
continued market expansion and to fund future OraTest manufacturing and
marketing costs. In anticipation of these potential requirements, effective
April 30, 1997, Zila entered into an investment agreement (the "Investment
Agreement") with Deere Park Capital Management (the "Investor") which allows the
Company to sell up to $25 million of Zila's common stock with the proceeds to be
used to fund OraTest marketing and general corporate purposes. The option to
sell stock to the Investor will remain available for a period of twelve months
following the effective date of the registration statement discussed below (the
"Twelve Month Period"). As part of the Investment Agreement, Zila sold $3
million of stock on April 30, 1997, and has committed to sell an additional $10
million of common stock to the Investor over the Twelve Month Period. At April
30, the net


                                       13
<PAGE>   14
proceeds of $2.9 million from the initial sale of shares were held in escrow.
During May 1997, the cash held in escrow was released to the Company.

      The Investment Agreement provides that Zila can obtain up to $2,000,000 at
any one time through the sale of the Company's common stock. All shares sold
will be at a 7% discount to the average low trading price of the Company's
common stock over a specified period of time, subject to a maximum purchase
price calculation. Sales under the Investment Agreement are subject to the
satisfaction of certain conditions, including registration of the shares, a
minimum market volume, and certain limitations on the number of shares of the
Company's common stock outstanding.

             As a commitment fee for keeping the equity line available for the
Twelve Month Period, the Company has issued warrants dated May 7, 1997 (the
"Warrants") to the Investor exercisable for 300,000 shares of common stock at an
exercise price of $8.6125 per share. The Warrants are exercisable for a
three-year period commencing October 31, 1997. A registration statement
pertaining to the shares issued and to be issued under the Investment Agreement
and the warrants is to be filed and effective no later than August 30, 1997
before any funds, other than the initial draw of $3,000,000, are drawn under the
Investment Agreement.

      In addition, the Company obtained a $500,000 bank line of credit in
December 1996, which was secured by trade accounts receivable, inventories and
rights to payment. This line of credit expired June 1, 1997. Interest is payable
monthly on the unpaid balance outstanding at the bank's prime rate (8.5% at
April 30, 1997) plus 1.75%. At April 30, 1997, the Company had borrowings of
$260,000 against the line of credit. Subsequent to April 30, 1997, all
outstanding balances against the line of credit were repaid.

PART II - OTHER INFORMATION

Item 1.- Legal Proceedings

      Colgate-Palmolive. On April 13, 1994, Zila filed a complaint in the United
States District Court for the District of Arizona, titled Zila Pharmaceuticals,
Inc. v. Colgate-Palmolive Company ("Colgate"), CIV No. 94-0756 PHX-EHC. The
complaint was served on Colgate on May 10, 1994. The complaint alleged that
Colgate's Orabase Gel product infringes the Company's U.S. Patent No. 5,081,158
(the "'158 Patent") which covers Zila's non-prescription, film-forming,
bioadhesive medications sold in food and drug stores nationwide. The complaint
sought to enjoin Colgate's manufacture and distribution of Orabase Gel and
requested an award of damages in an appropriate amount. The case


                                       14
<PAGE>   15
was settled on March 6, 1997 and had no material impact on the Company's
financial statements.

      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. In November 1996, Bio-Dental
was granted a summary judgment in which the court ruled in favor of Bio-Dental.
The plaintiffs filed a motion to reconsider the summary judgment ruling, which
was denied by the court in January 1997. Having lost the summary judgment ruling
and later having this ruling upheld, the plaintiffs are in the process of filing
an appeal. Bio-Dental will continue to vigorously defend against the claims set
forth in the lawsuit; however, a contingent liability has been accrued to cover
probable losses.

      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 5 - Other information

      Bio-Dental Technologies. On January 8, 1997, the Company's merger with
      Bio-Dental Technologies Corporation ("Bio-Dental") was completed. On
      December 30, 1996, Bio-Dental's shareholders approved the all-stock
      transaction which provided for a per share exchange of .825 shares of the
      Company's common stock for each share of Bio-Dental common stock
      outstanding.

      The Bio-Dental merger has been accounted for as a pooling of interests,
      and accordingly, the condensed consolidated financial statements give
      retroactive effect to the Bio-Dental merger and include the combined
      operations of Zila and Bio-Dental for all periods presented.

      Cygnus Imaging, Inc. On April 4, 1997, the Company acquired Cygnus
      Imaging, Inc., a small privately held company located in Scottsdale,
      Arizona that manufactures and distributes intra-oral oral camera systems
      and other dental imaging products. The acquisition was accounted for as a
      purchase and resulted in the issuance of approximately 260,000 shares of
      Zila common stock and the recording of approximately $2,059,000 of
      goodwill. The Company is still evaluating certain contingencies that could
      impact the allocation of the purchase price.
