years then ended and for the period from inception, May 4, 1988, through
December 31, 1997, in conformity with generally accepted accounting principles.
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 of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

VIROTEX CORPORATION
(A DEVELOPMENT STAGE ENTERPRISE)
NOTES TO FINANCIAL STATEMENTS

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

         ViroTex Corporation (the "Company") was incorporated on May 4, 1988, to
         develop, manufacture and market topical dermatological pharmaceutical
         products. The Company has since evolved to a developer of proprietary
         drug delivery systems that use the skin and mucosa as the primary site
         of delivery. These technologies have a variety of product applications
         for local and systemic delivery of pharmaceutical compounds. The
         Company has operated as a development stage enterprise since its
         inception by devoting substantially all of its efforts to financial
         planning, raising capital, research, product and market development and
         out-licensing product. Following is a summary of the Company's
         significant accounting policies.

         CASH AND CASH EQUIVALENTS

         For purposes of the statements of cash flows, the Company considers all
         highly liquid investments purchased with an original maturity date of
         three months or less to be cash equivalents.

         INVENTORY

         Inventories, consisting of finished goods, are stated at the lower of
         cost or market. Cost is determined by the first-in, first out method.
         All inventories were sold, transferred or disposed of in 1996.

         PROPERTY AND EQUIPMENT

         Property and equipment are recorded at cost. Depreciation for property
         and equipment, excluding leasehold improvements, is provided over the
         estimated useful lives of the depreciable assets using the
         straight-line method for financial reporting purposes. Amortization of
         leasehold improvements is provided using the straight-line method over
         the estimated useful lives of the improvements or the remaining term of
         the lease, whichever is shorter. Additions or improvements that
         increase the value or extend the life of an asset are capitalized.
         Expenditures for normal maintenance and repairs are expensed as
         incurred. Disposals are removed from the accounts at cost less
         accumulated depreciation, and any gain or loss from disposition is
         reflected in the statements of operations.

         INCOME TAXES

         The Company uses the liability method of accounting for income taxes
         pursuant to Statement of Financial Accounting Standards No. 109 ("SFAS
         No. 109"). Under this method, deferred income taxes are recorded to
         reflect the tax consequences on future years of temporary differences
         between the tax basis of assets and liabilities and their financial
         amounts at year end. A valuation allowance is provided, if necessary,
         to reduce any resulting deferred tax assets to their net realizable
         value.

         REVENUE RECOGNITION

         Sales and royalty revenue is recognized as earned on the accrual basis
         of accounting. Research grants are recognized in income as work is
         performed. Deferred federal grants are recorded to reflect amounts
         received in excess of costs incurred. During 1997 and 1996, all of the
         Company's sales and royalty revenue was derived from one product,
         Viractin Cold Sore and Fever Blister medicine ("Viractin") (see Note
         11).

         RESEARCH AND DEVELOPMENT

         Costs of research and development are expensed as incurred.

         PATENTS

         The Company has applied for certain United States and foreign patents,
         some of which are currently pending. Patent costs, which consist
         primarily of legal fees, have been capitalized and are amortized,
         beginning at the patent issue date, using the straight-line method over
         periods ranging from 17 to 20 years. If such patents are rejected, the
         costs will be expensed at the date of rejection.

         LICENSE AGREEMENTS

         The Company periodically acquires rights to utilize technology and
         materials required to produce new products. License costs have been
         capitalized and are amortized using the straight-line method over a
         period of 3 years.

         ESTIMATES

         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.

         STOCK-BASED COMPENSATION

         In October 1995, the Financial Accounting Standards Board ("FASB")
         issued Statement of Financial Accounting Standards No. 123, "Accounting
         for Stock-Based Compensation" ("FAS 123"), which encourages, but does
         not require, all entities to record compensation expense on all
         stock-based compensation plans based upon fair value. However, it also
         allows an entity to continue to measure compensation costs for options
         granted to employees using the intrinsic value method of accounting
         prescribed by Accounting Principles Board ("APB") Opinion No. 25,
         "Accounting for Stock Issued to Employees." The Company accounts for
         compensation cost for stock issued to employees in accordance with APB
         Opinion No. 25. In accordance with FAS 123, the Company has disclosed
         pro forma compensation expense as if the fair value-based method of
         accounting had been applied. See Note 10.

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

         CONCENTRATION OF CREDIT RISK

         The Company maintains its cash account with a major investment bank.
         Management periodically assesses the financial condition of the
         institution and believes that any possible credit risk is minimal.

         RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1997, the FASB issued Statement of Financial Accounting
         Standards No. 130, "Reporting Comprehensive Income") ("SFAS 130"). SFAS
         130 establishes standards for the reporting and display of
         comprehensive income and its components (revenues, expenses, gains and
         losses) in a full set of general-purpose financial statements. It
         requires classification of the components of other comprehensive income
         by their nature in a financial statement and the display of the
         accumulated balance of the other comprehensive income separate from
         retained earnings and additional paid-in capital in the equity section
         of a statement of financial position. SFAS 130 is effective for years
         beginning after December 15, 1997, and is not expected to have a
         material impact on financial position or results of operation.

         stock to buy out a license agreement. As of December 31, 1997, the
         Company owed $125,000 to the licensor. These noncash transactions have

6.       STOCKHOLDERS' EQUITY:

         PREFERRED STOCK

         In August 1990, the Company's Articles of Incorporation were amended to
         authorize 5,000,000 shares of Serial Preferred Stock with a par value
         of $.001 per share. In April 1995, the Company's Articles of
         Incorporation were amended to increase the authorized shares of Serial
         Preferred Stock to 10,000,000 shares. The Company's Board of Directors
         is authorized to divide the Preferred Stock into series and to fix and
         determine the relative rights and preferences of each series.

         Prior to 1992, the Company issued 350,000 and 384,616 shares of Series
         A and B convertible Preferred Stock, respectively. In March and June
         1992, the Company issued 100,000 and 240,000 shares, respectively, of
         Series C convertible Preferred Stock for $510,000 cash. In May 1993,

         Stock for $1,600,000 cash and cancellation of a note payable in the
         principal amount of $100,000 to a stockholder. In November 1993, the

         1,100,000 shares of Series F convertible Preferred Stock for $2,200,000
         cash.

         The Series A, B, C, D, E and F Preferred Stock (the "Series") each have
         par values of $.001, are noncumulative and have liquidation preferences
         of $.50, $1.30, $1.50, $2.00, $1.50 and $2.00, respectively.
         Additionally, the Series are entitled to vote on all matters submitted
         to a vote of the stockholders on an "as if converted basis" and the
         holders of Series D and E Preferred Stock, together as a class, are
         each entitled to elect one director to the Board of Directors. The
         Series are also convertible, at the option of the holder, at any time
         after the date of issuance, into shares of common stock as is
         determined by the number of Preferred Stock shares outstanding divided
         by the respective liquidation preference amount. Additionally, each
         share of the Series shall automatically be converted into shares of
         common stock at its then effective conversion rate, as defined in the
         amended Articles of Incorporation, immediately upon the effectiveness
         of a registration statement under the Securities Act of 1933, as
         amended, with a firm commitment to underwrite the Company's common
         stock for aggregate gross proceeds greater than $10,000,000 and a per
         share price greater than $7.50.

         COMMON STOCK

         In April 1995, the Company's Articles of Incorporation were amended to
         increase the authorized shares of common stock to 15,000,000 shares.

         In March 1996, the Company issued 25,000 shares of its common stock at
         estimated fair value as of the date of grant as part of a license
         agreement (see Note 7).

         Subsequent to December 31, 1997, the Company modified its lease of
         office space. This modification requires monthly payments of $3,452
         from February 2000 through March 2003. In March 1998, the Company
         signed a lease with its landlord moving its research facilities to a
         new location. This new lease requires monthly payments of $9,715
         through March 2003. Upon execution of this lease, the Company was
         released from its previous lease of research facilities that required
         monthly payments of $2,335 through January 2000.

         EMPLOYMENT AGREEMENTS

         The Company entered into new employment agreements with two officers of
         the Company in fiscal year 1995. These agreements superseded two
         agreements previously entered into in fiscal years 1993 and 1992. Under
         the terms of the new agreements, the employees are entitled to
         compensation ranging from three to nine months if the employees are
         terminated prior to the expiration of the agreements. The Company
         entered into employment agreements with two new officers of the Company
         in fiscal year 1996. Under the terms of these agreements, the employees
         are entitled to compensation for three months if the employees are
         terminated prior to the expiration of the agreements.

7.      COMMITMENTS AND CONTINGENCIES, CONTINUED:

         LICENSE AGREEMENT

         In May 1990, the Company entered into a license agreement with
         Ginamarie Products (the "Licensor") for the purpose of undertaking
         development to manufacture, use and sell certain licensed products.
         Under the terms of the agreement, the Company paid a license fee of
         $10,000 and shall pay the Licensor royalties equal to the greater of
         two percent of the net sales of each licensed product or $25,000 per
         year commencing upon the expiration of four years from the effective
         date of the agreement.

         In March 1996, the Company bought out the license agreement for 25,000
         shares of common stock and $400,000 cash, of which $300,000 was placed
         in escrow to be paid out over a period of three years on a quarterly
         basis at $25,000 per quarter.



8.      FEDERAL INCOME TAXES:

</TABLE>

         Net operating loss carryforwards for financial reporting purposes and
         alternative minimum tax reporting purposes are approximately the same
         as those under the regular tax method.

         Special limitations exist under the tax law which may restrict the
         utilization of the regular tax net operating loss carryforwards.

         The Company provides a valuation allowance to reduce deferred income
         tax assets to their net realizable value. The tax effects of loss
         carryforwards that give rise to deferred income tax assets and the
         valuation allowance at December 31, 1997 and 1996 are as follows:

9.       RELATED PARTY TRANSACTIONS:

         The Company made payments for legal, research and development and
         consulting services provided by certain stockholders and/or directors
         for 1997 and 1996 totaling approximately $59,200 and $21,900,
         respectively.

         The Company's operating leases for office and research facilities (see
         Note 7) and long-term debt (see Note 5) obligations are with The
         Woodlands Corporation, a stockholder of the Company.

         During 1996, the Company borrowed and repaid $300,000 from Ventures
         Medical, L.P., a stockholder of the Company. The Company paid $3,863 of
         interest expense in connection with this borrowing.

10.      STOCK-BASED COMPENSATION:

         STOCK OPTION PLAN

         In May 1991, the stockholders approved the Company's 1991 Stock Option
         Plan (the "Plan"). The Plan, as amended, provides for the granting of
         500,000 stock options to officers, other key employees of the Company
         and independent contractors under the terms and conditions determined
         by the Board of Directors. Options granted may be either "incentive
         stock options," within the meaning of Section 422A of the Internal
         Revenue Code, or nonqualified options. The stock options vest over
         periods ranging from 2-5 years, and are exercisable over a period
         determined by the Board of Directors, but no longer than ten years from
         the date of grant. All options become exercisable in full in the event
         of a change in control, as defined by the board of directors. The
         option price is generally greater than or equal to the fair value of
         the common stock at the date of grant. In October 1994, the Board of
         Directors approved an additional 500,000 stock options under the Plan.
         In July 1996, the Board of Directors approved an additional 500,000
         stock options under the Plan. Following is an analysis of stock option
         activity in the Plan for the years ended December 31, 1997 and 1996.

</TABLE>


         As of December 31, 1997 and 1996, outstanding stock options which were
         exercisable totaled 816,830 and 416,691, respectively. As of December
         31, 1997, 1,364,274 options were outstanding with a weighted-average
         exercise price of $.25 and a weighted-average contractual life of 4.8
         years.

         The fair value of each stock option granted during 1997 and 1996 was
         estimated as of the date of grant using the minimum value method with
         the following weighted-average assumptions for grants in 1997 and 1996:
         no dividend yield; no volatility; risk-free interest rates ranging from
         5.63% to 6.80%; and expected option lives from 3.5 to 6 years.

         Pursuant to APB Opinion No. 25, the Company was not required to
         recognize a charge for compensation expense for equity-based
         compensation awarded in 1997 or 1996. If the fair value based method of
         accounting in FAS 123 had been applied, the Company would have
         recognized $13,799 in 1997 and $7,521 in 1996 as compensation expense.
         The initial effects of applying FAS 123 are not indicative of future
         amounts.

11.      ROYALTIES AND CORPORATE ALLIANCE FEES:

         In March 1996, the Company entered into a license agreement (the
         "Agreement") with Schering-Plough Healthcare Products, Inc. ("SPHCP")
         for the purpose of transferring certain trademarks, patents and
         technology associated with Viractin in North America and Mexico. Under
         the terms of the Agreement, SPHCP paid the Company a technology access
         fee of $750,000, which was recorded as license fees in the statements
         of operations. Additionally, SPHCP paid the Company royalties equal to
         the greater of ten percent of the net sales of Viractin or $150,000 at
         the end of each calendar quarter. For the years ended December 31, 1997
         and 1996, the Company recorded $320,000 and $300,000, respectively, in
         royalty revenue related to the Agreement. In July 1997, the Company and
         SPHCP mutually terminated the Agreement. In July 1997, the Company
         entered into an asset purchase agreement (the "Purchase Agreement")
         with CEP Holdings, Inc. ("CEP") for the purpose of transferring all
         trademarks, patents, technology and assets associated with Viractin.
         Under the terms of the Purchase Agreement, CEP paid the Company
         $4,500,000. CEP will also pay the Company royalties equal to ten
         percent of the net sales of Viractin at the end of each calendar
         quarter for five years commencing upon execution of the Purchase
         Agreement. For the year ended December 31, 1997, the Company recorded
         $67,600 in royalty revenue related to the Purchase Agreement.
         Approximately 97% of the Company's 1997 revenues were derived from the
         sale of Viractin and royalties received under terms of the agreements
         mentioned above.

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         The financial statements included herein are unaudited, condensed and
do not contain all information required by generally accepted accounting
principles to be included in a full set of financial statements. In the opinion
of management, all adjustments considered necessary (which consist only of
normal recurring accruals) for a fair presentation have been included. The
results of operations for any interim period are not necessarily indicative of
results of operations for the entire year. These financial statements should be
read in conjunction with the audited financial statements and notes thereto for
the year ended December 31, 1997 included with this report.

NOTE 2.  SUBSEQUENT EVENTS

         ViroTex develops over-the-counter and prescription products based on
proprietary drug delivery systems that provide topical and transmucosal delivery
of medications requiring quick onset of action. On November 24, 1998 Atrix
Laboratories, Inc. a Delaware corporation ("Atrix"), completed the acquisition
of ViroTex through the merger of its wholly-owned subsidiary, Atrix Acquisition
Corporation, a Delaware corporation, with and into ViroTex. 

         Under the terms of the Agreement and Plan of Reorganization dated
November 24, 1998 (the "Merger Agreement"), the stockholders of ViroTex are
entitled to receive $7.5 million in cash and $500,000 in value of shares of the
Registrant's common stock, $.001 par value (the "Common Stock"). In addition,
the ViroTex stockholders are entitled to receive additional consideration of up
to $3,000,000, payable in shares of Common Stock or cash, upon satisfaction of
certain earn-out events set forth in the Merger Agreement related to the
performance of certain products of ViroTex. Atrix also issued a warrant to
purchase shares of Common Stock in replacement of a warrant to purchase shares
of ViroTex common stock for partial payment of services provided to ViroTex, and
agreed to replace certain options held by employees of ViroTex who will become
employees or consultants of Atrix.

  INTRODUCTION TO UNAUDITED CONDENSED COMBINED PRO FORMA FINANCIAL STATEMENTS
                ATRIX LABORATORIES, INC. AND VIROTEX CORPORATION
                                  (UNAUDITED)

         The following unaudited condensed combined pro forma financial
statements are based on the historical financial statements of Atrix
Laboratories, Inc. ("Atrix") and ViroTex Corporation ("ViroTex") for the year
ended December 31, 1997 and the nine-month periods ended September 30, 1998. The
pro forma financial statements have been prepared to give effect to the merger
("Transaction") between Atrix and ViroTex.

         The accompanying Unaudited Condensed Combined Pro Forma Income
Statements for the year ended December 31, 1997 and for the nine month period
ended September 30, 1998 have been presented on the assumption that the
transactions occurred on January 1, 1997 and January 1, 1998, respectively. The
accompanying Unaudited Pro Forma Condensed Combined Balance Sheet as of
September 30, 1998 has been presented on the assumption that the transactions
occurred as of September 30, 1998. The unaudited pro forma adjustments are 
described in the accompanying notes.

         The unaudited pro forma financial information presented does not
attempt to quantify any operating expense synergies or cost reductions of the
combined operations of Atrix and ViroTex that may be realized after the
Transaction. Nor does the unaudited pro forma financial information consider the
incremental expense, capital or conversion costs which may be incurred as a
result of the Transaction.

         These unaudited pro forma financial statements are not necessarily
indicative of the results of operations that would have been reported if the
transactions had occurred at the time presented and are not necessarily
indicative of the results that will be achieved for future periods as a result
of the transactions. However, Atrix management does anticipate that the
acquisition will positively impact the Atrix financial condition and operating
results over the expectant lives of the acquired technologies.

         The pro forma financial information should be read in conjunction with
the historical financial statements of Atrix included in Form 10-K for the
period ended December 31, 1997 and the historical financial statements of
ViroTex included in this report.

         These unaudited condensed financial statements are prepared based on a
preliminary allocation of purchase price to the assets of ViroTex. This estimate
is subject to change as a result of further analysis of the amount allocated to
in process research and development.
