INDEPENDENT AUDITORS' REPORT


Board of Directors and Stockholders
Oxycal Laboratories, Inc.
Phoenix, Arizona

We have audited the accompanying consolidated balance sheet of Oxycal
Laboratories, Inc. and subsidiaries as of June 30, 1997, and the related
consolidated statements of income, stockholders' equity and cash flows for each
of the two years in the period ended June 30, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Oxycal Laboratories,
Inc. and subsidiaries at June 30, 1997, and the results of their operations and
their cash flows for each of the two years in the period ended June 30, 1997 in
conformity with generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.       NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         a patented food supplement. The Company's products are Ester-C(R)
         mineral ascorbates which are distributed worldwide, as detailed in Note
         8.

         USE OF ESTIMATES - The preparation of financial statements in
         conformity with generally accepted accounting principles necessarily
         requires management to make estimates and assumptions that affect the
         reported amounts of assets and liabilities and the 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.

         PRINCIPLES OF CONSOLIDATION - The consolidated financial statements
         include the accounts of Oxycal Laboratories, Inc. and its wholly-owned
         subsidiaries, Inter-Cal Corp. and Oxycal Exports, Inc. All significant
         intercompany balances and transactions have been eliminated in
         consolidation.

         CASH AND CASH EQUIVALENTS include cash on hand and in banks and cash

                  over the estimated benefit period which ranges from 10 to 20
                  years for patents and 15 years for trademarks. Research and
                  development costs totaling approximately $114,000 and $104,000
                  in 1997 and 1996, respectively, were expensed.

5.       STOCK OPTIONS

         The Company adopted a Stock Option and Incentive Plan (the "Plan")
         authorizing the Board of Directors to grant options to employees and
         directors of the Company to purchase up to 750,000 shares of the
         Company's stock. Options granted under the Plan have terms between 10
         and 15 years from the date of grant. At the adoption of the Plan, all
         previously issued stock options which were still outstanding were
         incorporated into the Plan without a change in the terms of those
         options. At June 30, 1997, there were no shares available for grant
         under this Plan.

         In addition, 36,602 options to purchase shares at $1.50 per share were
         granted during 1992 and 44,000 options to purchase shares at $1.50 per
         share were granted during 1997, outside the Plan.

         Stock options, and related information, outstanding as of June 30,
         1997, which expire at various dates through 2005 are summarized in the

</TABLE>

         All options outstanding were exercisable at June 30, 1997.

         The Company applies Accounting Principles Board Opinion No. 25,
         Accounting for Stock Issued to Employees, and related interpretations
         in accounting for its stock options. Accordingly, compensation cost for
         stock options is recorded as the excess, if any, of the fair value of
         the Company's common stock at the date of grant over the exercise price
         of the option. Compensation cost recognized in the Company's
         consolidated statement of income for 1997 of $331,531 is essentially
         the same as that determined in accordance with the methodology
         prescribed under SFAS No. 123, Accounting for Stock-Based Compensation.

         The fair value of options granted during 1997 was estimated on the date
         of grant using the Black-Scholes option-pricing model with the
         following weighted average assumptions: 6.25% risk-free interest rate,
         expected option lives of 1 year, and a 4.4% dividend yield.

         During 1987 and 1991, 493,341 options with exercise prices ranging from
         $.69 to $2.18 were issued to various officers, employees and directors
         of the Company. In consideration for the past service of the officers,
         employees and directors, the Company agreed to reimburse the required
         exercise price of those certain stock options at the date of exercise.
         The Company recorded a total of $717,141 of compensation expense at the
         time those options were granted, which represented the estimated fair
         value of 493,341 shares of the Company's common stock. Option prices
         above have not been reduced for the amounts to be reimbursed by the
         Company; such amounts total approximately $491,000 at June 30, 1997. At
         June 30, 1997, all 493,341 of these options remained outstanding.

6.       RELATED PARTY TRANSACTIONS

         For the year ended June 30, 1996, the Company incurred interest at 8%
         of approximately $1,600 on related party debt with an officer, director
         and stockholder of the Company of approximately $65,000 which was
         repaid in 1996.

         The Company has two distribution agreements with companies owned by
         minority stockholders. Sales under these agreements totaled
         approximately $3,961,000 and $3,971,000 for the years ended June 30,
         1997 and 1996, respectively. No commissions were paid to these
         companies during the years ended June 30, 1997 or 1996.

9.       COMMITMENTS AND CONTINGENCIES

         During 1995, the Company received an inquiry from the Federal Trade
         Commission ("FTC") regarding product claims made in the Company's
         advertising. The Company responded to the FTC's initial request for
         information and has submitted evidence which it believes supports its
         claims. During 1996, the FTC requested further information from the
         Company. The Company responded to the FTC's request for additional
         information. In October 1996, the FTC notified the Company that its
         investigation was completed and that its regional staff concluded that
         certain claims were not adequately substantiated. Subsequently,
         additional information was submitted to the FTC and meetings were held,
         with no resolution of the regional office's allegations. The FTC
         forwarded their complaint to the Bureau of Consumer Protection ("BCP")
         for their suggestion regarding dismissal or further action against the
         Company. The Company has met with the BCP to present evidence
         supporting its claims. The FTC has the authority, among other things,
         to request further information from the Company, to impose fines or to
         issue a potential consent order regarding advertising claims.

         The Company has a $200,000 unsecured bank line of credit available
         until June 1998. Interest on outstanding balances is at variable
         interest rates which were approximately 8.25% at June 30, 1997. No
         amounts were outstanding under the line of credit at June 30, 1997.

10.      401(k) DEFINED CONTRIBUTION PLAN

         The Company adopted a 401(k) defined contribution plan (the "Plan")
         effective November 1, 1995 for all eligible employees. An employee may
         contribute up to certain maximum amounts each year. Company
         contributions were $34,640 for 1997. The Company did not make a
         contribution to the Plan during 1996.

11.      NOTE TO UNAUDITED FINANCIAL STATEMENTS (UNAUDITED)

         The accompanying unaudited consolidated financial statements for the
         three months ended September 30, 1997 and 1996, have been prepared in
         accordance with generally accepted accounting principles for interim
         financial information. In the opinion of management, all adjustments
         and reclassifications considered necessary for a fair and comparable
         presentation have been included and are only of a normal recurring
         nature. Operating results for the three months ended September 30, 1997
         are not necessarily indicative of the results that may be expected for
         the year ending June 30, 1998.

         NEW PRONOUNCEMENTS - In June 1997, the Financial Accounting Standards
         Board ("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 establishes 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
         issued to shareholders. It also establishes standards for disclosures
         about products and services, geographic area and major customers. Both
         statements are effective for financial statements for periods beginning
         after December 15, 1997. The Company has not completed evaluating the
         impact of implementing the provisions of SFAS Nos. 130 and 131.

         (b)      Pro Forma Financial Information - The required pro forma
                  financial information is set forth below:

Zila, Inc. (the "Company" or "Zila"), through its wholly owned subsidiary Zila
Pharmaceuticals, Inc., completed its acquisition of the Peridex(R) product line
("Peridex") from The Procter & Gamble Company ("P&G") pursuant to the terms of
that Asset Sale and Purchase Agreement dated November 5, 1997 (the "Agreement")
between P&G, The Procter & Gamble Distributing Company and Zila Pharmaceuticals,
Inc. Peridex is a prescription anti-bacterial oral rinse.

Under the terms of the Agreement, the Company also acquired certain inventory,
technology, contract rights, trademarks and other intellectual property
associated with Peridex. The purchase price of the Peridex product line, which
was determined in arms-length negotiations, was $12 million plus the value of
the inventory acquired at the closing. Under the terms of the Agreement, the
purchase price is to be delivered to P&G as follows: $6 million was paid at
closing, $4 million is payable within 180 days after closing, $1 million is
payable within 12 months after closing and $1 million is payable within 24
months after closing. The initial $6 million payment of the purchase price was
drawn from the funds available pursuant to the terms of that certain Private
Equity Line of Credit Agreement dated as of April 30, 1997 (the "Equity
Financing") between Deere Park Capital Management and the Company.

On November 10, 1997 (the "Closing Date"), the Company acquired by merger (the
"Merger") Oxycal Laboratories, Incorporated ("Oxycal") pursuant to the terms of
the Acquisition Agreement and Plan of Merger dated October 28, 1997, by and
among the Company, Oxycal and Zila Acquisition Corp. ("Acquisition Corp.").
Under the terms of the Merger, Oxycal was merged into Zila Acquisition Corp., a
wholly owned subsidiary of Zila, with Oxycal being the surviving corporation.
After the Closing Date, all the issued and outstanding shares of Acquisition
Corp. were converted into the common stock of Oxycal, the separate existence of
Acquisition Corp. ceased, and Oxycal continued its corporate existence under the
laws of the State of Arizona as a wholly owned subsidiary of Zila. Under the
terms of the Merger, each outstanding share of Oxycal common stock was converted
into the right to receive per share cash consideration of $10.1795. The total
cash consideration equaled twenty eight million dollars ($28,000,000) (the
"Merger Consideration") which was reached by arms-length negotiations between
the Company and Oxycal. Oxycal develops, manufactures and markets a patented and
enhanced form of vitamin C under the trademark name Ester-C(R).

The Company raised the funds to consummate the Merger in a private placement of
30,000 shares of the Company's Series A Convertible Preferred Stock (the "Series
A Preferred Stock") and warrants to purchase 360,000 shares of the Company's
Common Stock (the "Warrants") for $30,000,000 (the "Preferred Stock Proceeds").
The shares of Series A Preferred Stock, the Warrants and the Preferred Stock
Proceeds were deposited into escrow and were released from escrow upon the
consummation of the Merger.

The unaudited pro forma condensed balance sheet at October 31, 1997 combines
historical financial information as if the acquisitions of Peridex and Oxycal
occurred on October 31, 1997. The unaudited pro forma condensed combined
statement of operations data for the year ended July 31, 1997 and the three
months ended October 31, 1997 combine historical statements of operations data
for the Company, Peridex and Oxycal, as if the acquisitions had occurred on
August 1, 1996.

The unaudited pro forma condensed combined balance sheet data at October 31,
1997 combines historical financial information of the Company at October 31,
1997 and Peridex and Oxycal at September 30, 1997. The unaudited pro forma
condensed combined statement of operations data for the three months ended
October 31, 1997 combines historical financial information of the Company for
the three months ended October 31, 1997 and Peridex and Oxycal for the three
months ended September 30, 1997. The unaudited pro forma condensed combined
statement of operations data for the year ended July 31, 1997 combines
historical financial information of the Company for the year ended July 31, 1997
and Peridex and Oxycal for the year ended June 30, 1997. As the most recent
fiscal year ends of both Peridex and Oxycal differ from the Company's fiscal
year end by less than 93 days, no adjustments were made to Peridex's or Oxycal's
statement of operations data for the purpose of the pro forma presentation.

The detailed assumptions used to prepare the unaudited pro forma condensed
combined financial information are contained herein. The unaudited pro form
condensed combined financial information reflects the use of the purchase method
of accounting for the acquisitions. The purchase price allocation used in the
preparation of the pro forma financial information is preliminary and subject to
change based upon final evaluations being performed.

The unaudited pro forma combined financial information assumes the initial $6
million payment of the purchase price for Peridex was drawn from the funds
available pursuant to the Equity Financing. The remaining amount of purchase
price of Peridex is reflected as current and long-term contractual obligations.
The unaudited pro forma combined financial information assumes the acquisition
of Oxycal was funded from the private placement of the Series A Preferred Stock
and Warrants.

The pro forma data are not necessarily indicative of the financial position or
results of operations which would actually have been reported had the
transaction been consummated at the date mentioned above or which may be
reported in the future.

The pro forma data should be read in conjunction with the notes to unaudited pro
forma condensed combined financial information and the historical financial
statements and notes thereto of Zila and Peridex (incorporated by reference
herein) and Oxycal (contained elsewhere herein).

(b)   Represents income tax receivable resulting from Oxycal generating income
      tax deductions immediately prior to the acquisition date. The tax
      deduction is a result of certain Oxycal option holders exercising their
      options to purchase common stock which generated an ordinary deduction for
      Oxycal.

(c)   Represents the following adjustments to inventories:

</TABLE>

      The purchase price for the Peridex inventory is subject to adjustment
      based on the actual value of inventory purchased. Based on information
      received from P&G, the amount of such adjustment may result in an increase
      in the purchase price of approximately $100,000. The purchase price
      adjustments to Oxycal inventories reflect adjustments to value raw
      materials inventories at replacement cost and finished goods inventories
      at estimated selling prices less costs of disposal and selling effort
      profit.

(d)   Represents purchase accounting adjustment to increase the value of
      property, plant and equipment of Oxycal to current replacement cost.

      While the Company has yet to complete the allocation of the excess of cost
      over net assets acquired to the specific assets acquired, based on its
      preliminary estimate, the Company believes that the excess will be
      allocated principally to patents, trademarks and goodwill, which is
      estimated to be amortized over 15 years for Peridex and 20 years for
      Oxycal.



(f)   Represents pro forma adjustment for contractual obligation to pay
      remaining purchase price of Peridex as follows: $4 million is payable
      within 180 days after closing, $1 million is payable within 12 months
      after closing and $1 million is payable within 24 months after closing.
      The contractual obligation does not have a stated interest rate and,
      therefore, has been discounted using an imputed interest rate that
      approximates the rate the Company would have negotiated in a similar
      transaction.

(g)   Represents eliminating entries for combination purposes.

                        FOR THE YEAR ENDED JULY 31, 1997


(a)   Represents the amortization of excess of assets acquired over liabilities
      assumed of Peridex and Oxycal. While the Company has yet to complete the
      allocation of the excess of cost over net assets acquired to the specific
      assets acquired, based on its preliminary estimate, the Company believes
      that the excess will be allocated principally to patents, trademarks and
      goodwill, which is estimated to be amortized over 15 years for Peridex and
      20 years for Oxycal.

(b)   Represents amortization of discount on contractual obligation.


(c)   Represents elimination of income taxes associated with Oxycal. The
      historical financial statements of Peridex reflect only direct revenues
      and direct expenses of the Peridex brand of P&G and do not reflect a
      provision for income taxes. It is assumed that net operating loss
      carryfowards of the Company would be utilized to offset income from
      Peridex and Oxycal.

(d)   Includes 982,000 shares issued in connection with the Equity Financing, as
      if such shares were issued on August 1, 1996.
