             ANNUAL REPORT FOR THE FISCAL YEAR ENDED MARCH 31, 1996

                                     PART I

ITEM 1.  DESCRIPTION OF BUSINESS.

GENERAL.

         Bio-Dental Technologies Corporation, formerly Springfield Capital
Corporation (hereinafter referred to as the "Company" or the "Registrant"), was
organized under the laws of the State of Colorado on April 5, 1988, to evaluate,
structure and complete a merger with or acquisition of private corporations,
partnerships or sole proprietorships. On July 13, 1990, the Company changed its
name from "Springfield Capital Corporation" to "Bio-Dental Technologies
Corporation," providing a name and image more accurately reflecting its business
plan.

(1) The material set forth in this Form 10-KSB and its accompanying exhibits
includes forward-looking statements and references to anticipated future events
and developments that are based on management's beliefs and expectations. There
is no assurance that such statements and references will prove to be correct.
Such statements and references are set forth herein in reliance upon numerous
assumptions that may or may not prove to be accurate or correct. The major
assumptions upon which these forward-looking statements and references are based
include the following: (1) the consummation of the proposed merger transaction
between the Company and Zila, Inc.; (2) the consummation of the Company's
proposed transaction with Young Innovations, Inc. ("Young"), which would involve
Young's cash buy-out of the Company's rights to receive future royalties from
Denticator International, Inc.; (3) the successful restructuring of the
operations of the Company's IDT operating subsidiary and the redirection of
IDT's marketing focus away from hardware-based comprehensive computer solutions
and towards the sale of practice management software systems and intra-oral
cameras; (4) the growing market demand for IDT's technology products; (5) the
improvements of operating margins on products sold by the Company's dental
products distribution unit, The Supply House; (6) the continued growth in sales
and market share of The Supply House; (7) the success of The Supply House in
obtaining additional contracts with managed dental care insurance companies and
in increasing its sales as a result of such contracts; (8) the obtaining of FDA
approval of Zila, Inc.'s oral cancer diagnostic product, OraTest; (9) the
successful realization of the anticipated market benefits of combining the
market appeal of the OraTest product with the strength of the Company's existing


                                        3
<PAGE>   4
product distribution network; (10) the adequacy of available debt and equity
capital to fund inventories, receivables, product introduction and marketing;
(11) the Company's ability to settle the Wildwood litigation on terms favorable
to the Company; and (12) the retention of key management personnel following
consummation of the Company's proposed merger with Zila, Inc.


         Formation and Disposition of Denticator International, Inc. Subsidiary.
In March 1991, the Company incorporated a wholly owned subsidiary, Denticator
International, Inc. ("DII") and transferred the Company's manufacturing
operations into DII in exchange for the issuance of a $600,282 note to the
Company with monthly principal payments of $10,005 plus interest at 150% of the
Company's cost of funds from April 1, 1994 through March 31, 1999. Interest only
payments were made from March 1991 through March 31, 1994. Effective with the
date of incorporation, the Company entered into a licensing agreement with DII
for the manufacture and sale of certain dental products owned by the Company.
Under this agreement DII pays the Company a monthly royalty equal to the greater
of $30,000 or 17% of net sales of DII. In addition, the agreement provides for
further royalties to be paid to the Company if DII achieves certain levels of
profitability.

         On March 31, 1991, the Company sold all of the outstanding capital
stock of DII to DII's former operations manager, thus allowing the Company to
cease operating as a manufacturing concern, and to focus on its distribution
operations. The sales agreement incorporated the licensing agreement described
above. The details of this transaction are described in the Company's Form 8-K
dated March 31, 1991, which is hereby incorporated by this reference.

         Effective April 1, 1994, the licensing agreement was amended. The terms
included herein reflect all amendments. In March 1999, DII has the option to
purchase the rights under this licensing agreement. The purchase price is equal
to the greater of 1.5 times average annual sales of DII during the period
covered by the amended agreement (April 1, 1994 - March 31, 1999) or six times
the average pre-tax income of DII after certain adjustments. The purchase price
will be reduced by 50% of the additional royalties paid by DII between April 1,
1994 and March 31, 1999.

         In connection with the amendments to the licensing agreement, warrants
to purchase 50,000 shares of the Company's restricted common stock were issued
to DII at an exercise price of $4.00 per share. These warrants expire on March
31, 2004.


                                        4
<PAGE>   5
         Effective January 1995, DII increased the minimum royalty to the
Company to $43,000 per month in exchange for the Company waiving the provision
in the agreement whereby the Company could purchase products made by DII at
specified prices.

         The Company's revenues are affected, in part, by the revenue levels and
successful operations of the Denticator product line, as operated and controlled
by DII.

         On January 19, 1996, the Company entered into an agreement to defer
principal payments on the note payable from DII, beginning with the principal
payment due for the month of October 1995 and extending through September 1996.
The agreement expires September 30, 1996. Additionally, this agreement provides
a basic understanding between the Company and DII with respect to the proceeds
of any sale of DII which may occur prior to September 30, 1996.

         On May 10, 1996, the Company executed a letter of intent which sets
forth a general understanding of a transaction by which Young Innovations Inc.
(Young) will purchase certain assets and liabilities of DII. If the transaction
contemplated by the letter of intent is consummated, it is expected the Company
would receive approximately $7.5 million in exchange for the cancellation of its
March 31, 1991, as amended, licensing agreement dated March 31, 1991, with DII.
Under the terms of the Young letter of intent any amounts owed and outstanding
to the Company by DII as of the closing date of this transaction would be
assumed by Young. Young would issue a credit to the Company against future
purchases (Product Credit) in an amount equal to, and payment in full for, all
accrued royalties, notes current and long term and accrued interest owed by DII
to the Company. The Product Credit would be usable by the Company for future
purchase of products from Young and any of its affiliates at prevailing prices
in effect at the time of the purchases. The Company, Young and DII currently are
engaged in negotiations of the final terms and conditions of the transaction
which is expected to close by the end of July 1996.

THE ACQUISITION OF SAN DIEGO DENTAL SUPPLY, INC. ("SDDS").

         Acquisition of SDDS. On March 4, 1991, the Company purchased all of the
outstanding stock of SDDS of El Cajon, California, in exchange for the issuance
of 390,000 shares of the Company's restricted common stock. Subsequently, 37,500
of these shares were surrendered by the former shareholders in accordance with
specific terms of the agreement. The terms of this purchase, along with the
financial statements of SDDS, are set forth in the Company's Form 8-K filing
dated July 29, 1990, and filed in April, 1991, and hereby incorporated by this
reference.


                                        5
<PAGE>   6
         SDDS was incorporated under the laws of the State of California on
November 20, 1987. SDDS, which operated under the trade name "The Supply House",
was subsequently merged into Ryker Dental of Kentucky, Inc. ("Ryker"), as
described below, and the surviving entity (Ryker) continues to operate as "The
Supply House", a distributor of professional dental supplies and an authorized
dealer for several lines of dental products.

THE MERGER OF SAN DIEGO DENTAL SUPPLY, INC. INTO RYKER DENTAL OF
KENTUCKY, INC.

         Merger of Ryker Dental of Kentucky. On January 3, 1994 (but effective
after the close of business on December 31, 1993), the Company acquired all of
the outstanding capital stock of Ryker Dental of Kentucky, Inc. ("Ryker")
pursuant to the merger ("Merger") of the Company's wholly-owned subsidiary, San
Diego Dental Supply, Inc. ("SDDS"), with and into Ryker with Ryker being the
surviving entity. Pursuant to the Merger, the Company issued an aggregate of
220,000 shares of its previously unissued restricted Common Stock to the
shareholders of Ryker in cancellation of the shares of Ryker Common Stock owned
by such shareholders. The Company became the sole shareholder of Ryker through
the conversion of each outstanding share of Common Stock of SDDS into one share
of Common Stock of Ryker. As part of the transaction, the Company retired
approximately $720,000 of Ryker's debt, thereby releasing the former
shareholders of Ryker from their personal guarantees on such debt. The Articles
of Merger were filed with the Secretary of State of Kentucky on January 3, 1994.

         The transaction was accounted for as a purchase. The purchase price was
allocated to the fair value of Ryker's assets and liabilities and the excess of
$388,186 was allocated to goodwill. The goodwill is being amortized on the
straight line method over a period of twenty years, in accordance with the
Company's accounting policies. The depreciable assets acquired are being
depreciated over the remaining useful life on a straight line basis, in
accordance with the Company's accounting policies.

         The two former shareholders of Ryker each entered into employment
agreements to continue managing Ryker for a period of three (3) years. As a part
of these employment agreements, each former shareholder received $40,000 in cash
bonuses over the first year of the agreement, in addition to an annual salary of
$80,000 each. Under the terms of the employment agreements, each shareholder may
also earn performance bonuses each year of up to $10,000 cash and options to
purchase 10,000 shares of the Company's common stock, exercisable at the fair
market value of the common stock on the date of the option grant. In addition,


                                        6
<PAGE>   7
the two former shareholders of Ryker each received $60,000 cash as consideration
for entering into a non-competition agreement with the Company. These
non-competition agreements extend for a period of eighteen months following the
employee's termination of employment with the Company.

         The assets of Ryker consist mainly of trade inventory and accounts
receivable. The amount of consideration given was determined by good-faith,
arms-length negotiations between the parties. The shareholders of Ryker were
Danny D. Ramsey and George Barton Mahan. As a result of the merger, Mr. Mahan
was appointed to the Company's Board of Directors in January 1994.

         Ryker distributes professional dental supplies and equipment to dental
offices nationwide under the trade name, "The Supply House". In addition, Ryker
also sells large equipment, such as sterilizers, compressors, and dental lights
and chairs, previously not sold by the Company. Ryker also has an in-house
design department to assist dentists in the architectural design of their
offices.

         Effective June 1994, the Company began to utilize Ryker's strategic
location as its eastern distribution center, saving the Company up to several
thousands of dollars per month in freight costs. Ryker also augments the
Company's existing product line, allowing the Company to offer a much broader
range of products to its customers nationwide.

         Ryker now operates from two (2) leased facilities: one in Rancho
Cordova, California and one in Lexington, Kentucky, and has approximately
ninety-two (92) employees.


MANAGEMENT AGREEMENTS AND SUBSEQUENT ACQUISITION OF ORAL VISION,
INC.

         Marketing Agreement with Oral-Vision, Inc. In August 1992, the Company
was granted exclusive U.S. marketing rights to the intra-oral camera
manufactured by Oral-Vision, Inc. ("Oral Vision") of New Albany, Indiana. The
agreement provided that the Company would receive a commission on all sales of
Oral-Vision cameras over a three year period.

         The camera allows a patient to see into the recesses of his own mouth
to better understand the treatment plans being recommended by his dentist. The
goal of this tool is to enhance dentist-patient communication and to improve a
patient's understanding of his dental needs, thereby increasing his acceptance
of recommended treatment options. This greater acceptance leads to better
patient care and increased revenue


                                        7
<PAGE>   8
levels for those dentists using the Oral-Vision intra-oral camera.

         Management Agreement with Oral-Vision, Inc. Effective June 1, 1993, the
Marketing Agreement outlined above was replaced and superseded by a Management
Agreement under which Bio-Dental was hired by Oral Vision to manage the business
operations of Oral Vision.

         Under the terms of this Management Agreement, Oral Vision agreed to pay
all expenses related to the business as well as financing any necessary
investment in inventory, accounts receivable, fixed assets, etc. All of the
assets remained with Oral Vision, while the Company was responsible for managing
those assets on Oral Vision's behalf.

         The Company was paid a management fee by Oral Vision, on a monthly
basis, equal to one-half of Oral Vision's pre-tax income after reimbursing the
Company for any expenses incurred on Oral Vision's behalf. As discussed below,
the Company purchased all the assets and certain liabilities of Oral Vision
effective January 1, 1994. The Management Agreement was terminated on the
effective date of the purchase. Net revenues received prior to acquisition were
$502,209 in 1994.

         Acquisition of Oral Vision Assets and Liabilities. On July 6, 1994, the
Company signed an agreement and purchased the assets and certain liabilities of
Oral Vision, Inc. The acquisition was effective as of January 1, 1994, as the
Company effectively maintained control of the operations, assets and liabilities
of Oral Vision, Inc. as of that date. In connection with this purchase, the
Company issued 272,727 shares of its previously unissued restricted common stock
to the sole shareholder of Oral Vision, Inc., Dr. William Oakes. The assets
acquired consist mainly of trade inventory and accounts receivable. As part of
the transaction, on July 6, 1994, the Company retired approximately $515,000 of
the assumed liabilities, thereby


                                        8
<PAGE>   9
releasing certain security interests held by a vendor of Oral Vision, Inc.

         The transaction has been accounted for as a purchase. The purchase
price was allocated to the fair value of Oral Vision's assets and liabilities
and the excess of $215,919 was allocated to goodwill. The goodwill is being
amortized on the straight line method over a period of twenty years, in
accordance with the Company's accounting policies. The assets and liabilities
are held in Integrated Dental Technologies, Inc. ("IDT") a wholly-owned
subsidiary of the Company formed for this purpose.

         In addition, Dr. William Oakes agreed to remain with the Company under
the terms of a four year consulting agreement. Under the terms of the consulting
agreement, Dr. Oakes received $30,000 in the first year and will receive $75,000
per year for each of the following three years.

         The Company expanded the scope of products offered through IDT beyond
the Oral Vision cameras to include such innovative technologies as filmless
x-ray systems, automated patient and periodontal charting systems, and
multi-media patient-education systems. Beginning in March 1995, IDT began
selling personal computer hardware to its customers.

         The Company integrates all of these technologies through a proprietary
common-user interface developed by the Company. All of these modular
technologies were marketed via IDT's education-based seminar series and a
national outside sales force. These seminars are accredited for continuing
education credits by the American Dental Association and the Academy of General
Dentistry.

         Effective January, 1996, the Company began a restructuring of its IDT
operations. This restructure reduced the emphasis on the integration of the
technologies discussed previously, including computer hardware and filmless
x-ray, and focused IDT's marketing and selling effort on the intra-oral camera
and software products offered by IDT. These products are believed to


                                        9
<PAGE>   10
have the largest market potential and offer the highest gross margins of the
various products which made up the IDT product line. IDT's education-based
seminar series continued with emphasis on the use of the intra-oral camera and
related products.

         Acquisition of Crown Systems Assets and Liabilities. On November 14,
1994, the Company signed an agreement and purchased the assets and certain
liabilities of Crown Systems, Inc. ("Crown"), effective November 1, 1994. In
connection with this purchase, the Company issued 47,501 shares of its
previously unissued restricted common stock to Crown. The assets acquired
consisted mainly of accounts receivable and dental practice management software
rights. As part of the transaction, the Company retired approximately $205,000
of assumed liabilities.

         The transaction was accounted for as a purchase. The purchase price was
allocated to software rights and the fair value of Crown's assets and
liabilities. Software rights were valued at $287,985 and are being amortized on
the straight line method over a period of five years, in accordance with the
Company's accounting policies. The depreciable assets acquired will be
depreciated over the remaining useful life on a straight line basis, in
accordance with the Company's accounting policies. The assets and liabilities of
Crown are held in IDT.

         Crown developed and marketed dental practice management software
systems and will continue to develop additional software for IDT. As part of the
transaction, the principals of Crown entered into one year employment agreements
and three year non-compete agreements with IDT.

         Since the date of the acquisition, the former principals of Crown have
been instrumental in developing IDT's common user interface, which allowed for
the integration of all of IDT's technology based products.

         Current Operations - The Supply House. Ryker Dental of Kentucky, one of
the Company's operating subsidiaries, operates under the trade name "The Supply
House." The Supply House is a national distributor of professional dental
supplies, carrying brand names such as Eastman Kodak, Dentsply, Hu-Friedy,
Premier and 3M. Most of The Supply House's sales are through telemarketing and
direct mail, as opposed to deploying the more traditional outside sales force.
As a result, The Supply House believes it can operate more efficiently than its
major competitors.

         There are estimated to be over 120,000 practicing dentists in the
United States. The annual market for dental supplies in the U.S. is
approximately $2.0 billion, representing approximately $16,000 per dentist.

         Currently, the Company represents the products of over 400 dental
manufacturers. It is believed that these products constitute the vast majority
of supplies used in the day-to-day operations of a dental practice. For example,
the Company carries a broad line of dental alloys, x-ray film, composite filling
materials, impression materials, latex gloves, diamond and carbide cutting
instruments, anesthetics, asepsis and infection control products, operative,
hygiene and surgical instruments, and a variety of other widely used items.

         Historically, the Company has carried only consumable supplies and very
small equipment, such as hand pieces. With the Ryker acquisition, the Company is
now distributing a select group of large items of dental equipment, such as
compressors, sterilizers, dental lights and chairs.

         Traditionally, dentists have purchased their supplies from local
full-service supply companies, or from mail-order firms. The Supply House is
attempting to combine the level of service typically associated with the local
dealer with the convenience and competitive prices found with most mail-order
firms. The Supply House can do this partially as a result of the increased


                                       11
<PAGE>   12
efficiencies brought about by telemarketing. Where a traditional outside sales
person might call on 10 to 15 accounts per day, a telemarketer can reach 50 to
70 offices. Additionally, telemarketing has been shown to significantly increase
the response to direct mail pieces (like catalogs), giving The Supply House a
decided advantage over mail order firms which do not follow-up by phone.

         The Supply House's Competition. There are approximately 300 dental
supply dealers and mail order supply houses in the United States, some of which
have significantly greater financial resources than the Company. The Company's
sales make up less than 2% of the total market for dental supplies. The
Company's position with respect to its competitors is difficult to determine
since most of the companies are privately-held and do not disclose financial
information. However, the Company believes that approximately 50 percent of the
market is dominated by three (3) public companies: Patterson Dental, Sullivan
Dental, and Henry Schein.

         Current Operations - IDT. Integrated Dental Technologies, Inc. ("IDT")
represents the Company's other wholly-owned operating subsidiary.

         IDT was formed on the premise that there was a growing market demand
for integrated, computer-based technology dental systems, yet there was no
company prepared to deliver such a product. Through the fiscal year 1995
acquisitions of Crown Systems Inc. and Oral Vision Inc., and distribution
agreements for other key products, IDT developed a broad array of products
designed to enhance the efficiency and profitability of the dental practice.

         These products included an intra-oral camera, filmless x-ray system,
patient and periodontal charting system, practice management computer system,
electronic claims processing, and multi-media patient education.

         In addition, through some proprietary Windows(TM) software written by
IDT's own programmers, IDT integrated all of these technologies into one system,
thereby creating the first virtually "paperless" dental office.


                                       12
<PAGE>   13
         In addition to marketing the product, IDT also provided full
installation, training and support for both hardware and software elements of
the system.

         While this market is reported to be one of the fastest growing segments
of the dental products industry, IDT found that the present market demand was
not sufficient to allow IDT to operate profitably with this type of product
offering. As a result of lower-than-expected sales coupled with higher marketing
and support costs, IDT incurred substantial losses during the fiscal year ending
March 31, 1996. Thus, in the fourth quarter of fiscal year 1996, IDT announced
its plan to restructure its operations to focus exclusively on the Company's
software and intra-oral camera products.

         It is believed that the software and intra-oral camera products have
the largest existing market potential, are well positioned to compete in their
respective markets, and offer higher margins to the Company. As a part of this
restructuring, the Company discontinued its promotion and sales of computer
hardware, of the Schick filmless x-ray system, and fully-integrated "paperless"
systems.

         This restructuring, which was phased in during the fourth quarter of
fiscal 1996, has allowed the Company to reduce its ongoing operating expenses
while focusing more attention on those products which the Company believes
currently have the broadest market appeal and offer the Company the greatest
margins.

         The Company took a $271,631 restructuring charge in the fourth quarter
of fiscal 1996 to cover employee severance and other reserves for expenses
related to the business operations being phased out. As a result of the
restructuring, $307,331 of inventory was written off to cost of products sold
and the reserve for returned product was increased by $250,000. In addition, as
the Company introduced its new, upgraded camera system, a $312,026 inventory
reserve was taken against old intra-oral camera and related inventory. Total
restructuring charges, inventory writedowns and the reserve increases totaled
$1,140,988.

         As previously mentioned, IDT ceased selling its own line of computer
hardware (although it still supports those existing customers who already have
IDT hardware in their office) as part of this restructuring.


                                       13
<PAGE>   14
         In an effort to continue to provide its customers with a
"one-stop-shop" for their computer needs, IDT entered into an agreement with
DELL Computer Corporation to provide a line of specially-configured computers
directly to IDT customers. DELL will also agree to support their hardware
through their contracted field-support organization during the full warranty
period.

SECURITIES ISSUANCES AND OTHER EVENTS.

         In September of 1991, the Company initiated a private placement,
offering to sell a total of 600,000 units at $2.25 per unit, with each unit
consisting of one share of 7 3/4% Series A Participating Convertible Preferred
Stock and one Series A Redeemable Common Stock Purchase Warrant. The Company
sold 90,667 units under this private placement.

         On October 1, 1991, the Company entered into a letter agreement with
Ladenburg, Thalmann & Co., Inc., a New York investment banking firm
("Ladenburg"). The Company retained Ladenburg to provide investment banking
advice and services. The term of the letter agreement extended through September
30, 1992. In lieu of Ladenburg's normal retainer, the Company agreed to issue to
Ladenburg a common stock purchase warrant, expiring on September 30, 1996,
providing Ladenburg the right to purchase 200,000 shares of the Company's common
stock at an exercise price of $3.50 per share. The exercise price was
subsequently adjusted to $3.11 per share pursuant to a ratchet anti-dilution
provision contained in the warrant, which was triggered by the issuance of the
ICP warrants described below. In April 1994, 96,333 shares of the Company's
common stock were issued to Ladenburg as a result of a cashless exercise of the
common stock purchase warrant, which reduced the purchase rights from 200,000
shares to 96,333 shares.

         On January 6, 1992, the Company entered into a letter agreement with
Josephberg Grosz & Co., Inc., a New York investment banking firm ("JG"). The
Company retained JG to assist the Company in raising capital through a financing
transaction the nature of which was undecided at the time of the letter
agreement. As partial consideration for their services, JG received 12,000
shares of the Company's restricted common stock, which became "freely tradeable"
upon the effectiveness of the Company's Form S-1 registration statement on June
30, 1992 (described below).


                                       14
<PAGE>   15
         On May 1, 1992, the Company filed a registration statement on Form S-1
(which is incorporated herein by this reference) with the Securities and
Exchange Commission to register shares of common stock issued in an earlier
private placement, as well as other outstanding shares of the Company. The Form
S-1 registration statement, which was declared effective on June 30, 1992,
registered a total of 1,622,656 shares of the Company's common stock. The
registration significantly increased the total number of "freely tradeable"
shares of the Company's common stock outstanding.

         On September 7, 1992, the Company issued 1,004,000 shares of
unregistered common stock to 34 investors (the "Investors") at a price of $1.50
per share in a private placement. In connection with the transaction, the
Company issued warrants for the purchase of 150,000 shares of common stock to
International Capital Partners, Inc., a Connecticut corporation ("ICP") and lead
member of the investor group. The transaction was pursuant to a Stock Purchase
Agreement, dated August 31, 1992, by and among the Company, ICP and the
Investors (the "Agreement").

         The Agreement features a purchase price adjustment provision whereby
the Company agreed to adjust the purchase price retroactively by the issuance of
additional shares to the Investors upon the occurrence of certain events.
Specifically, a provision of this Agreement allowed for the issuance of 220,390
additional shares of common stock if certain earnings benchmarks were not
achieved in fiscal 1995. Due to the various strategic investments and other
factors cited earlier, these benchmarks were not, in fact, achieved. However,
since the 1995 earnings per share benchmark was achieved in fiscal 1994 (a full
year ahead of schedule), the Company requested a waiver to this additional
shares provision. The waiver request was denied and the Company issued the
additional 220,390 shares of common stock on October 17, 1995. The Agreement
gives to the Investors demand registration rights for up to 20% of their common
stock and all of their warrants (one time only), and piggyback registration
rights on the balance of their shares. The proceeds from the private placement
were used primarily to retire existing debt and to expand inventories to meet
increasing demand for the Company's products.

         In May 1994, the Company offered to sell up to 300,000 shares of its
restricted common stock in a private placement. Sale of the stock was restricted
to non-"U.S. persons" within the


                                       15
<PAGE>   16
meaning of Regulation S as promulgated by the United States Securities and
Exchange Commission. The placement was completed in June 1994 when the Company
issued 100,000 shares of restricted common stock, with net proceeds of
approximately $380,000, after commissions and other expenses. Certain transfer
restrictions apply to the shares.

         On April 1, 1996, the Company issued two (2) Term Notes in a private
placement to two (2) institutional investors in connection with the borrowing of
$1,250,000. These Term Notes accrue interest at a rate of 12% per annum and
accrued interest is due and payable on September 30, 1996 and March 29, 1997.
The principal amounts of the Term Notes are due not later than March 29, 1997.
As additional consideration for the Term Notes, the Company issued warrants to
the Lenders which totaled 250,000 warrants at an exercise price of $3.03 and
50,000 warrants at an exercise price of $3.03 to International Capital Partners,
Inc. as part payment for the placement fee. For additional information on the
Term Notes and associated warrants, see the section on Debt Financing under Item
6 below (Management Discussion and Analysis of Financial Condition and Results
of Operations).


EMPLOYEES.

         As of May 31, 1996, the Company and its operating subsidiaries employed
one hundred and twenty-four (124) people. Of these employees, three (3) are
executive officers and fifty (50) employees are involved in sales functions. The
accounting and administration departments employ forty-two (42) people, with
twenty-nine (29) employees in the purchasing and distribution departments. No
employees are represented by a labor union, nor are there any current labor
relations complaints on file with any agency.

ITEM 2.  PROPERTIES.

         The Company holds leases on three (3) separate facilities and is a
guarantor on a fourth lease. The Company leases 25,000 square feet of
office/warehouse space in a concrete building located at 11291 Sunrise Park
Drive, Rancho Cordova, California. The current lease rate for the Rancho Cordova
facility is $9,270 per month, and is constant for the duration of the lease. The
lease for the Rancho Cordova facility expires on November 30,


                                       16
<PAGE>   17
1996, however the Company has an option to renew the lease for two subsequent
five-year terms. The Company's executive offices are located in the Rancho
Cordova facility.

         The Company leases 19,200 square feet in an office/warehouse complex at
172 Lisle Road, Lexington, Kentucky. The current lease rate is $2,800 per month,
and expires on October 31, 1998.

         The Company also leases 1,500 square feet of office space located at
3935 Eagle Creek Parkway in Indianapolis, Indiana. The current lease rate is
$1,715 per month. The lease expired in September 1995, and continued on a month
to month basis pending evaluation of other suitable space. On May 31, 1996, IDT
entered into a three year lease for 2,000 square feet beginning July 15, 1996 in
an office complex at 6021-A West 71st Street, Indianapolis, Indiana. The current
lease rate is $1,783 per month, and expires on July 14, 1999. The Company is a
guarantor of this lease. The Company anticipates terminating its lease at 3935
Eagle Creek Parkway, Indianapolis, Indiana.

         In addition, the Company is a guarantor of a lease obligation of its
former subsidiary, Denticator International, Inc. ("DII"). This guarantee will
terminate upon the sale of DII, should the sale occur. DII leases 6,400 square
feet of office/warehouse space in a one-story concrete building in Rancho
Cordova, California. The lease rate on this facility is $2,100 per month, and
remains fixed until its expiration in May 1997.





ITEM 3.  LEGAL PROCEEDINGS.

         Oral Vision, Inc. (still owned by Dr. Oakes) filed a claim against a
former consultant alleging breach of contract, misappropriation of trade
secrets, and other similar causes of action. Oral Vision, Inc. sought to secure
a judgment against this consultant and his affiliate companies. The Company has
subsequently been advised that the Consultant, and his resulting firm, have
since ceased operation. As a result, the Company, as the current owner of the
Oral Vision claim, agreed to settle the litigation in March of 1996 for $22,000
in cash payable to the Company. To date, however, no payments have been received
toward this settlement amount.


                                       17
<PAGE>   18
         Also, in 1993 Oral Vision, Inc. received a letter from a product
manufacturer alleging that the Oral Vision product, which was manufactured for
Oral Vision by a sub-contractor, infringed upon one or more patents held by the
complaining product manufacturer. The Company is no longer marketing the camera
upon which this original complaint was alleged.

         As reported earlier in the Company's Form 10-QSB for the quarter ended
September 30, 1995, dated November 13, 1995 and the Company's Form 10-QSB for
the quarter ended December 31, 1995, dated February 13, 1996, the Company was
been served with a lawsuit (the "Wildwood litigation") which was filed on July
6, 1995, in the California Superior Court, County of Sacramento, against the
Company, its transfer agent, OTR, Inc., and Mr. G. Michael Montross, a
shareholder of the Company (Wildwood Limited Partnership Oversight Committee, et
al, v. Bio-Dental Technologies Corporation, et al; Sacramento Superior Court No.
95A503733).

         The Wildwood litigation alleges that in 1992, G. Michael Montross
pledged 200,000 shares of the Company's common stock owned by Mr. Montross to an
agent for the plaintiffs, to secure debts allegedly owing by Mr. Montross to the
plaintiffs. The lawsuit further alleges that Mr. Montross subsequently executed
a fraudulent affidavit of loss claiming that the certificates for the 200,000
shares had been lost or destroyed. Mr. Montross thereby achieved a reissuance of
such shares through the Company's transfer agent, OTR, Inc. The plaintiffs
allege that Mr. Montross subsequently defaulted on his debts to the plaintiffs
and that plaintiffs foreclosed on the Company's shares that their agent held as
security for Mr. Montross' debts. The Wildwood litigation seeks the recovery of
general and special damages from the defendants, or in the alternative, that the
200,000 shares in dispute be reissued in their names. Plaintiffs claim that they
have lost security for more than $320,000 in debts owed by Mr. Montross, and
have suffered damages in the amount of the highest fair market value that the
200,000 shares have obtained since October 16, 1992, estimated by the plaintiffs
at $1,250,000.

         The Company has referred this matter to outside counsel with the
directions that counsel vigorously defend against the claims set forth in the
Wildwood litigation. The Company has filed an Answer, which denies all of the
material allegations of the Wildwood litigation and asserts various affirmative
defenses.


                                       18
<PAGE>   19
The Company and OTR have tendered the defense of this lawsuit to each other.
Both tenders have been denied. The parties to this lawsuit have been unable to
locate Mr. Montross and thus have been unable to serve him personally with any
of the pleadings in this matter. Mr. Montross has been served with the Company's
summonses and complaint by publication and a default was then entered against
him.

         The Company has also filed a Cross-Complaint for Indemnity, Negligence,
Fraudulent Misrepresentation, Conversion, Imposition of a Constructive Trust and
Conspiracy against Mr. Montross, OTR, Inc. and the Plaintiffs. Specifically, the
Company alleges that its transfer agent, OTR, was negligent for not securing a
surety bond from Mr. Montross at the time Mr. Montross filed an affidavit of
loss claiming the certificates for the 200,000 shares had been lost or
destroyed. OTR has filed a Cross-Complaint against Mr. Montross and the Company
for Implied Indemnity, Contractual Indemnity, Negligence, Fraudulent
Misrepresentation, Conversion and Imposition of Constructive Trust. The Company
has filed an Answer which denies all of the material allegations of the
Cross-Complaint.

         The Company has tendered the defense of this lawsuit to its insurance
carriers. The insurance carriers have denied coverage by claiming that one or
more policy exclusions apply. While the Company disagrees with the insurance
carriers' position, it does not appear likely that the insurance carriers will
become involved voluntarily in this litigation.

         The Wildwood litigation was referred by the Court to non-binding
arbitration. After a brief hearing, the court-appointed arbitrator rendered a
decision unfavorable to the Company. In his ruling, the arbitrator found that
the Company was liable to the plaintiffs for either 200,000 shares of the
Company's stock or $1,250,000. The Company has now filed a request for Trial De
Novo, which has the effect of vacating the arbitration award.

         Because formal discovery is at an early stage in this matter, the
Company is not in a position at this time to evaluate the merits of the various
claims.

         On April 5, 1996, an action was filed whereby Ryker Dental of Kentucky,
Inc. dba The Supply House, and Curtis Rocca, along with Dr. Woody Oakes, Dr.
Travis McFee, and Excellence in Dentistry, Inc., were alleged to have written
and/or published


                                       19
<PAGE>   20
libelous statements about a dental management consulting group, the "Practice
Builder". This allegedly libelous letter was written by Mr. Rocca as a "Letter
to the Editor" to the dental newsletter published by Doctors Oakes and McFee.

         This letter was written in response to the Practice Builder's
introduction of a multi-level marketing program designed to sell dental supplies
to dentists. Under this program, the Practice Builder made certain claims about
how much money a dentist would save on his supplies, along with how much money
he could make through downstream "commissions".

         Mr. Rocca and the Company continue to believe that the statements made
in Mr. Rocca's letter are true, and the Company plans to defend this action
vigorously. In addition, the Company has been notified that, subject to a
reservation of rights, the defense of this action will be covered under the
Company's general liability insurance policy.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

         No matters were submitted to a vote of security holders of the Company
during the fourth quarter of the Company's fiscal year ended March 31, 1996.

ITEM 6.  MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS.

         The Year Ended March 31, 1996 -- Results of Operations. Fiscal 1996
marked the second full year of operations of both Ryker Dental of Kentucky, Inc.
and Oral Vision, following the Company's acquisition of these entities effective
January 1, 1994. In addition, it was the first full year of operations following
the November 1, 1994 acquisition of Crown Systems, Inc.

         For fiscal 1996, the Company's net revenues rose to $33,091,216, a 5
percent increase over revenues of $31,582,277 for fiscal 1995. The growth in net
revenues was attributable mainly to the ability of the Company's distribution
subsidiary, "The Supply House", to increase its average volume per customer.

         Sales for The Supply House rose to $24,270,762, up 13 percent from
$21,550,535 last year. The Company's other operating subsidiary, Integrated
Dental Technologies ("IDT") experienced a decline in revenues from $8,366,043 in
fiscal 1995 to $7,441,783 this year. This decline in revenues resulted mainly as
a result of the Company's launch of the IDT "paperless" dental office. This
product offering, while very popular in concept, was met with little initial
demand. Previously, IDT had sold only dental practice management software
systems and intra-oral cameras on a stand-alone basis. When the Company began
focusing on these larger, "integrated" systems, sales of the individual
components declined.

         In December 1995, the Company announced that it was discontinuing its
"paperless" dental office offering, and


                                       21
<PAGE>   22
returning to its previously-successful strategy of selling just intra-oral
cameras and dental practice management software packages.

         The Company believes that these products represent the greatest market
opportunity for IDT for a number of reasons. Among these are: 1) these markets
are believed to be the most developed markets in the dental technology field at
this time, 2) the Company believes that IDT's products are well positioned to
compete in these markets, and 3) these products offer the highest gross margins
and lowest service costs. As a result of this strategic change in market
positioning and product focus, the Company should post significantly improved
results from IDT in fiscal 1997.

         It is management's belief that the large dedication of both human and
financial resources devoted to IDT during the past year also had an adverse
effect on the operations of The Supply House. As a relatively small company,
much of the available resources were channeled toward addressing the many
challenges inherent in the IDT business strategy and operation. With IDT's
simpler product offerings and market strategy designed for fiscal 1997, the
Company believes that it should be able to turn more of its attention and
resources to continuing to grow The Supply House.

         The Company has received three endorsements from Managed Dental Care
insurance companies wherein such insurance companies are endorsing the services
of The Supply House and IDT to its member dentists. Currently, these three
organizations represent nearly 18,000 dentists. Under the terms of these
endorsements, The Supply House is offering preferred pricing to dentists
associated with these insurance companies. Through the endorsements and the
attractive pricing offers, the Company hopes to rapidly expand its sales to
participating dentists. Managed care sales are expected to provide slightly
lower gross margins but the sales volume increase from these contracts
should improve the net income of The Supply House.

         The Company has identified this niche as a growing area within
dentistry, and is actively seeking out additional relationships similar to those
which it has arranged thus far.

         The Company believes that The Supply House's "Guaranteed Lowest Prices"
approach is ideally positioned to appeal to those dentists opting to participate
in a managed care environment.

         In addition, the productivity-enhancing tools of IDT create an
additional opportunity for the dentist to more easily operate


                                       22
<PAGE>   23
his practice profitably under the lower-reimbursement policies of managed care.

         Thus, the Company believes that it is well positioned to continue to
win additional contracts and endorsements as more dentists are forced to cut
costs and look for more cost-effective and efficient ways to run their practice.

         Royalty revenues from Denticator International, Inc. ("DII") decreased
from $1,665,699 last year to $1,408,671 this fiscal year. This reduction came
mainly as a result of lower levels of profitability at DII, which had a
resulting effect on royalties payable to the Company. It is believed that the
lower profitability levels were due mainly to increased competition in the
marketplace, an expanded marketing budget, more favorable employee benefit
programs, and increased legal expenses.

         Subsequent to the end of fiscal 1996, the Company signed a letter of
intent to sell its economic interest in the future royalty payments from DII to
Young Innovations, Inc. of Earth City, MO ("Young"). The terms of this
transaction call for the Company to receive approximately $7.5 million in cash
in lieu of future royalties. In addition, any monies owing to the Company from
DII at the time of the closing shall be converted to a "product credit" upon
which The Supply House can draw free product at a specified rate until depleted.
This product credit is expected to be approximately $1 million. The transaction
with Young is part of a larger transaction whereby Young will be acquiring the
assets and liabilities of DII. The transaction, expected to close in July 1996,
is subject to due diligence of both parties, as well as the parties' ability to
execute a mutually acceptable definitive agreement.

         Cost of products sold rose from $21,252,851 in fiscal 1995 to
$23,926,770 this year. This 13 percent increase was directly attributable to
increased sales volume and, to a lesser degree, a change in the Company's mix of
products and services. Cost of products sold increased as a percentage of net
revenues, from 67 percent in fiscal 1995 to 72 percent this year. This increase
was a result of a variety of factors. Foremost among these were: 1) decreased
gross margins at The Supply House, 2) the changing product mix to include lower
margin items (filmless x-ray and computer hardware) at IDT, and 3) decreased
royalty revenues. Additionally, $307,331 of inventory was written off as a
result of the IDT restructuring program implemented during the fourth


                                       23
<PAGE>   24
quarter. Also, a reserve of $312,026 was established in recognition of a
potential degradation of inventory value of older model intra-oral camera
inventory, as the Company released its newer model camera. The inventory
writedown and the reserve were not included as "restructuring charges", but
rather were taken against cost of products sold.

         The Company believes that newly-adopted pricing and product-mix
strategies adopted during the first quarter of fiscal 1997 should enable the
Company to reverse this trend toward lower gross margins.

         Selling, general and administrative costs rose from $10,653,386 in
fiscal 1995, or 34 percent of revenues, to $11,829,832, or 36 percent of
revenues this year. While part of this increase is directly attributable to the
higher revenue level, the bulk of the increase related to the higher than
expected costs of marketing, selling and supporting the various products of IDT.
Particularly expensive to support were the Company's filmless x-ray and computer
hardware products. Since these products are no longer part of the revised IDT
product offerings for fiscal 1997, management believes that its selling, general
and administrative expenses , as a percentage of sales, should decline. In
addition, IDT's more focused marketing approach should further reduce sales and
marketing expense, as the Company will strive to communicate a more limited, yet
more direct, marketing message.

         Operating expenses for The Supply House were slightly less than
expected, resulting partly from lower-than-anticipated sales, as well as
effective cost-containment methods invoked by the Company.

         Additional expenses incurred this fiscal year, but not last year, were
$271,631 of restructuring charges taken by the Company related to the
restructuring of its IDT subsidiary. The restructuring charges are specifically
outlined as follows:

<TABLE>
         <S>                               <C>    
         Writedown of other assets         $90,002
         Future contractual obligations     85,000
         Employee severance                 13,800
         Other                              82,829
</TABLE>

         As mentioned earlier, management's decision to restructure its IDT
operation also resulted in an inventory writedown of


                                       24
<PAGE>   25
$307,331 and an increase to the reserve for returned product of $250,000. In
addition, a reserve of $312,026 was established in recognition of a potential
degradation in value of older model intra-oral cameras and related inventory.
The inventory writedown and the reserve for older cameras were charged against
cost of products sold. The reserve for returned product was charged against net
revenes. Total restructuring charges, inventory writedowns and the reserve
increase totaled $1,140,988.

         Management decided to restructure its IDT operations largely as a
result of a change in marketing focus. Beginning in late fiscal 1995, IDT
endeavored to be the first Company in the United States to be able to provide a
dentist with a "paperless" dental office, combining such state-of-the-art dental
technologies as: 1) digital, filmless x-ray, 2) intra-oral camera, 3)
computerized patient charting, 4) multi-media patient education, and 5)
Windows(TM) based dental practice management software.

         It was believed that there was a growing trend toward greater
automation of dental practices in the United States. However, while the Company
still believes this to be true, this trend was not sufficiently developed nor
large enough in scope to support the extensive marketing and support costs
necessary to bring a revolutionary new product like this to market.

         IDT provided, and continues to provide, nationwide support for its
customers for any software or hardware products purchased from IDT. It quickly
became very expensive for IDT to provide this level of customer support to its
users on a nationwide basis.

         As a result of these and other factors, in January 1996 the Company
decided to initiate the restructuring of its IDT operations in order to focus on
selling just intra-oral cameras and dental practice management software, as
outlined above. Management believes that this restructuring will enable IDT to
produce significantly more positive results as the Company focuses strictly on
those products which have large established markets, offer the Company
attractive profit margins, and are well positioned to compete in their
respective markets.

         The restructuring was largely completed during the fourth quarter, and
the few remaining aspects should be fully executed during the first quarter of
fiscal 1997.


                                       25
<PAGE>   26
         Interest and other income decreased from $203,130 last year to $81,849
this fiscal year. The majority of the decrease was due to the termination of
lease revenues from DII in March 1995, as scheduled. These lease charges were
billed to DII throughout all of last fiscal year but there were no lease charges
to DII in this fiscal year.

         Interest expense increased from $127,185 last year to $231,722 this
fiscal year. The increase was due to the increased borrowings from the bank,
both on the line of credit and on a term note.

         The Company reported a loss before taxes of ($3,563,977), compared to a
pre-tax loss of ($599,437) last year. This year's after tax loss was
($2,265,977), or ($0.36)per share, compared to a net loss of ($419,437), or
($0.07) per share, in fiscal 1995.

         This loss resulted primarily from the poor financial performance of
IDT, although lower gross margins within The Supply House and higher interest
expense also contributed somewhat.

         The Company believes that the strategic changes outlined above should
enable the Company to report significantly improved results in fiscal 1997.


         Liquidity and Capital Resources. As of March 31, 1996, the Company held
total assets of $10,966,592. Of these, $8,626,608 (78%) consisted of cash,
accounts receivable, inventories, deferred income taxes and other current
assets. As of this same date, the Company had total liabilities of $7,165,756,
all being current liabilities. The Company's current ratio at March 31, 1996 was
1.20, down from 1.65 at the end of fiscal 1995. The debt to equity ratio was
1.87, up from 1.07 at the end of fiscal 1995. These ratios, specifically debt to
equity, were affected by the net loss for the year.

          Cash and cash equivalents were $612,911 for fiscal 1996 compared to
$322,848 for fiscal 1995. Inventory decreased from $5,318,845 at March 31, 1995
to $3,667,161 at March 31, 1996. This decrease resulted primarily from the
Company's restructure of IDT and the write down of inventory value for
discontinued products and other inventory allowances in the fourth quarter of
fiscal 1996.


                                       26
<PAGE>   27
      Accounts receivable decreased from $2,137,276 at March 31, 1995 to
$1,973,943 at March 31, 1996. This decrease resulted primarily from continued
focus on managing the Company's credit and collection efforts and higher credit
card sales for The Supply House during fiscal 1996.

         Prepaid expenses and other current assets decreased from $471,931 for
fiscal 1995 to $272,197 for fiscal 1996. The decrease in prepaids and other
assets results from reduced direct mailing expenditures and marketing costs
associated with seminars, trade shows and other special events for IDT.

         Deferred income taxes totaled $1,614,500 at March 31, 1996 compared to
$474,500 at March 31, 1995. The $1,140,000 increase relates to the tax benefit
resulting from the current year operating results. The tax benefit is expected
to be recognized by the Company as a result of the sale of DII in fiscal 1997.

         Property and equipment was $717,152 at March 31, 1996 compared to
$888,410 at March 31, 1995. Additions to property and equipment before current
year depreciation were $172,424. Accumulated depreciation increased $306,891
during fiscal 1996.

         Assets of business transferred under contractual arrangements decreased
from $490,518 at March 31, 1995 to $440,354 at March 31, 1996. The decrease
resulted from principal payments made by DII on the Company's note receivable.

         Intangible assets were $1,227,862 at March 31, 1996, compared to
$1,354,852 at March 31, 1995. The net decrease of $126,990 resulted primarily
from the amortization of these assets during fiscal 1996. Software rights are
amortized using a five year amortization in accordance with the Company's
accounting policies.

         Accounts payable and accrued expenses increased from $4,303,907 at
March 31, 1995 to $4,851,628 at March 31, 1996. The $547,721 increase results
from accruals (approximately $272,000) related to the IDT restructuring
initiated during the fourth quarter of fiscal 1996 with the remainder related to
increases in vendor accounts payable.

         Notes payable at March 31, 1996 totaled $2,109,459, all classified as a
current liability. Total notes payable at March 31, 1995 were $2,034,000, of
which $1,311,770 was classified as a


                                       27
<PAGE>   28
current liability. The increase in the current portion of notes payable results
from a modification to the Company's bank agreements whereby the Term Note is
due September 30, 1996 compared to the previous maturity date of May 1, 1998.

         Deferred revenues were $204,669 at March 31, 1996, compared to $125,035
at March 31, 1995. Deferred revenues represent prepaid customer support fees,
prepaid seminar fees from customers and customer deposits or pre-payments on
sales orders not yet delivered or completed. The $79,634 increase results
primarily from an increase in prepaid customer support fees related to IDT's
software products.

         Total stockholders' equity at March 31, 1996 was $3,830,836, which
represents a decrease of $2,200,249 from March 31, 1995. Retained earnings
decreased $2,265,977 during fiscal 1996 as a result of operations. Common stock
and capital contributed in excess of par value increased $65,728 with the
increase resulting from the issuance of additional shares related to the Crown
Systems, Inc. acquisition in fiscal 1995, fiscal 1995 employee stock option
contribution, and the issuance of additional shares of common stock to lecturing
dentists pursuant to the acquisition agreement of Oral Vision, Inc.

         In accordance with generally accepted accounting principles, the
balance sheet does not reflect the future interest and royalty income which
Bio-Dental contractually receives from DII, its former manufacturing subsidiary.
This royalty was a monthly minimum of $30,000 for the year ended March 31, 1994
and from April through December 1994. Effective January 1995, the monthly
minimum royalty payment increased to $43,000 per month. However, actual royalty
payments have continued to be higher than the minimum requirements.

         If the Company were to repeatedly have losses similar to that which it
experienced in fiscal 1996, the Company could run into liquidity problems and
eventually have difficulty meeting its credit obligations. The Company believes,
however, that these levels of losses are unlikely to continue in fiscal 1997
and, in fact, believes that the Company will return to profitability in fiscal
1997.

         Debt Financing. In December 1992, the Company secured a $1 million line
of credit from The Bank of California. In December 1993, the Company obtained an
increase to this line of credit


                                       28
<PAGE>   29
from $1 million to $1.5 million. In August 1994, the line was increased again,
from $1.5 million to $3 million. In addition to the line of credit, a $1 million
term note with the bank was secured in March 1995. In July 1995, the bank
amended certain covenants regarding tangible net worth, total indebtedness and
profitability requirements. The line expired on August 31, 1995. The bank
subsequently extended the agreement through November 19, 1995. Effective October
31, 1995, the bank modified the agreement and a Second Amended and Restated
Credit Agreement was executed with a February 29, 1996 expiration date.

         The Second Amended and Restated Credit Agreement changed the interest
rate on both the line of credit and term loan to prime plus 1.25%, compared to
the previous rate of prime plus 0.75%. Since the Company's eligible inventory
and accounts receivable have never been sufficient to take full advantage of a
$3 million credit line, the maximum borrowing base on the line of credit was
reduced to $2.5 million, an amount more consistent with the Company's eligible
asset base.

         The Second Amended and Restated Credit Agreement expired on February
29, 1996 and the Company and the bank subsequently executed a Replacement
Revolving Credit Note and Modification Agreement effective March 31, 1996. The
Modification Agreement amended the maximum borrowing base to $1,394,000 and the
interest rate on the line of credit and term note was changed to prime plus
2.5%, compared to the previous rate of prime plus 1.25%. The line of credit and
term note each expire September 30, 1996. In addition to monthly interest
payments on the line of credit and term note, monthly principal payments of
$27,777 are due on the term note.

         On April 1, 1996, in accordance with the terms of the Modification
Agreement, the Company secured additional funding pursuant to an agreement to
borrow $1,250,000 from two institutional investors (Lenders). The Term Notes
accrue interest at the rate of 12% per annum and accrued interest is due and
payable on September 30, 1996 and March 29, 1997.

         As additional consideration for the Term Notes, the Company issued
warrants to the Lenders which totaled 250,000 warrants at an exercise price of
$3.03 and 50,000 warrants at an exercise price of $3.03 to International Capital
Partners, Inc. as part payment for the placement fee. Under the terms of the
agreement,


                                       29
<PAGE>   30
the Company is required to repay the outstanding principal of the Term Notes and
accrued and unpaid interest before July 31, 1996 in order to avoid the issuance
of additional warrant shares, but in no event will the repayment occur later
than March 29, 1997. On June 7, 1996, the Company filed a Form 8-K (which is
incorporated herein by this reference) describing the details of these
subordinated loans.

         The Company's debt agreements with The Bank of California contain
various covenants regarding working capital, net worth and total indebtedness
among other items, which became effective January 1, 1996 and thereafter.
Effective March 31, 1996, the Company was not in compliance with the covenant
regarding the maintenance of current assets in an amount not less than
$2,500,000 in excess of current liabilities. The Company's failure in the future
to comply with these covenants would constitute technical defaults under its
credit arrangements and the bank could theoretically exercise certain creditor
rights with the Company.

         The Company has used its line of credit for working capital to finance
it operations, specifically in information systems and in IDT. The term loan
with the bank was used primarily to fund the retirement of existing debt
associated with the acquisitions of Ryker, Oral Vision and Crown Systems. The
balance outstanding on the line of credit as of March 31, 1996 was $1,394,000
and the balance on the note was $715,459. Because the subordinated Term Notes
were not funded until April 1, 1996, there was no balance on these notes
outstanding as of March 31, 1996.

         Effect of Inflation and Price Increases on the Company's Operations. As
mentioned earlier, The Supply House experienced decreased gross margins in
fiscal 1996. This was due mostly to suppliers of The Supply House's products
increasing the costs of such products at a greater rate than The Supply House
could raise its selling prices, due to price competition in the marketplace and
the timing of its catalog release.

         The Supply House estimates that price increases for products it sells
will average approximately 4 percent in fiscal 1997. The Supply House believes
that new pricing strategies adopted during the first quarter of fiscal 1997 will
address these anticipated cost increases and should enable The Supply House to
prevent a decrease in gross margins for its non-managed care sales. Managed care
sales are expected to provide slightly lower gross margins but the sales volume
increase from these contracts should improve the net income of The Supply House.


                                       30
<PAGE>   31
         The current rate of inflation is not believed to have any material
effect on the operations of the Company's IDT subsidiary.

         The Year Ended March 31, 1995 -- Results of Operations. The year ended
March 31, 1995 represented the fourth full year of operations following the
Company's acquisition of SDDS and the disposition of DII. In addition, fiscal
1995 included one full year of operations of both Ryker Dental of Kentucky, Inc.
and Oral Vision, following the Company's acquisition of these entities effective
January 1, 1994. For fiscal 1995, the Company's net revenues rose to
$31,582,277, a 58% increase over revenues of $20,017,039 for fiscal 1994. The
growth in revenues was attributable mainly to the acquisitions of these two
entities, although revenues of previously existing distribution operations also
continued to grow.

         Of the $11,600,000 increase in product sales, approximately $5,200,000
came as a result of Oral Vision (and the subsequent formation of IDT), while an
additional $4,000,000 came from the acquisition of Ryker. The remaining $2.4
million of revenue growth was internally generated by The Supply House, the
Company's dental products distribution subsidiary.

         While these acquisitions provided substantial revenue growth, they were
not without their share of associated costs.

         The growth in revenues from operations existing prior to the
acquisitions was somewhat affected by a number of start-up and non-recurring
events which occurred during the year. First, the Company's acquisition of Ryker
Dental Corporation in January, 1994 required a significant amount of resources
be dedicated to incorporating Ryker's method of operation within that of The
Supply House. In addition, the Company converted The Supply House (both
California and Kentucky operations), and later Integrated Dental Technologies
(IDT), to a completely new computer system.

         The $5.2 million growth in IDT revenues was approximately $2 million
less than expected for fiscal 1995. The acquisition of Oral Vision, the
subsequent formation of IDT, and the significant efforts required to build the
IDT business unit caused management attention to be focused more on this
entity's product and organizational development rather than short-term


                                       31
<PAGE>   32
revenue growth. In addition, the development of IDT's fully-integrated system
was not completed until after year-end. The Company believes that this shift in
sales focus to the integrated system, coupled with the inability of the Company
to deliver this system prior to year-end, also affected revenues.

         All of these issues imposed a drain on the Company's management and
staff resources, which impeded the Company's attainment of its growth goals for
fiscal 1995. The Company believed that many of these issues had been resolved,
which would enable management to refocus its attention on revenue and earnings
growth.

         As anticipated, royalty revenues from DII were virtually unchanged from
last year, indicating the stability of Denticator's position within the
marketplace and the relatively mature nature of this market. Royalty revenues
were $1,665,699 for 1995 compared to fiscal 1994's $1,665,664. The Company sold
DII in March 1991 in exchange for a royalty arrangement.

         Cost of products sold rose from $12,703,618, or 69 percent of product
sales, in fiscal 1994 to $21,252,851, or 71 percent of product sales in fiscal
1995. The reduction in gross margin percent arose largely as a result of a delay
in the production of The Supply House's catalog, which forced the Company to
honor last year's pricing for several additional months, even after cost
increases had been imposed upon The Supply House from its suppliers. In
addition, during the first nine months of fiscal 1994 the Company earned
profit-sharing dollars associated with its role as the manager of Oral Vision,
Inc. These dollars earned were recorded as revenues with no costs associated
with them, thereby providing 100 percent gross margin on these dollars.
Subsequent to the acquisition of Oral Vision in January 1994, the Company
records all operational activity (revenues, cost of sales and expenses) and, as
such, gross margins were naturally reduced.

         Selling, general and administrative expenses for the year totaled
$10,653,386, or 34% of net revenues, as compared to $5,123,874, or 26% of net
revenues, in 1994.

         The increase in expenses came primarily as a result of two factors.
First, the acquisition of Ryker added the staff, facility and ongoing operations
associated with that


                                       32
<PAGE>   33
organization. Secondly, the formation, development and marketing of the new IDT
business unit added a very large portion of this increased cost structure. Costs
associated with IDT were both start-up and recurring in nature. Included in the
start-up category are: 1) product development costs, 2) up-front marketing costs
associated with securing the distribution rights for IDT's filmless x-ray
system, 3) the recruiting, hiring and training of new lecturers as well as a
team of product sales representatives, 4) costs associated with the Company's
conversion to a more sophisticated computer system, 5) designing and
implementing a new series of educational seminars, and 6) the actual acquisition
of Oral Vision, Inc. and Crown Systems, Inc.

         Recurring costs associated with IDT include: 1) company marketing and
promotion, 2) product marketing and sales activity, educational seminars and
symposiums, 3) technical support services, and 4) general administrative support
and overhead.

         Operating costs and expenses for the year totaled $32,257,659, or 102%
of net revenues, as compared to $17,971,646, or 90% of net revenues, in 1994.

         Many of the above factors which served to increase the Company's
expense structure had a corresponding effect on the Company's profitability.

         For the fourth quarter ended March 31, 1995, the Company lost
approximately $(993,000), as compared to net earnings of $455,523 for the fourth
quarter ended March 31, 1994. In the fourth quarter of fiscal 1995 the Company
recorded certain adjustments, aggregating approximately $485,000, which were
required to adjust recorded accounts payable to agree to the actual amounts
payable. The adjustments were required because of the Company's prior failure to
recognize payable obligations at the time when products had been received and
were on hand, but the invoices from the product vendor had not yet been
processed. The result of this increased the net loss by approximately $291,000,
or $.05 per share, net of taxes.

         The Company incurred a net loss of $(419,437) in fiscal 1995, as
compared to net earnings of $1,553,953 in the prior year.


                                       33
<PAGE>   34
         Total fiscal 1995 net loss per share was $(0.07) as compared to net
income per share of $0.27 for the year prior.

         The decrease in profitability can be mainly attributed to the large
start up (and to a lesser degree, the ongoing operating) expenses of
Bio-Dental's new IDT subsidiary, as cited above.

         To the best of Management's knowledge, IDT was the first company in the
United States to be able to provide a dentist with a complete, virtually
"paperless" dental office, combining such state-of-the-art dental technologies
as: 1) filmless x-ray, 2) intra-oral camera, 3) computerized charting, 4)
multi-media patient education, and 5) Windows(TM)-based practice management
software.

         There is a growing trend toward automation of dental practices within
the United States. IDT was positioning itself to be the leader within the field
of integrating these new technologies into the dental practice. The Company
believed that each of the products represented in its IDT product line were, or
would be, among the highest quality products available in their respective
categories. System prices generally range from $4,000 for software only, to
around $100,000 for a ten-user system, completely networked into every operatory
within the dentist's practice.

         IDT has nationwide support capabilities for both hardware and software
service such that one call to IDT should serve to resolve any user problem -
whether it be hardware or software related. The Company charges an annual
support fee for this service.

         With regard to The Supply House, several non-recurring expenses caused
an increase in operating expenses here too. Most noteworthy of these are the
costs associated with integrating Ryker Dental into the operations of The Supply
House, and the


                                       34

computer conversions of both the California and Kentucky operations.

         To a lesser degree, the Company's investment in the redesign of its
revised catalog format, featuring full-color photographs and expanded product
descriptions for virtually every product, also affected the year's expenses.
This new catalog design required significant one-time investments in
photography, design, and copy writing. The benefits of this re-design should be
realized for many years, yet the up-front development has been expensed (with
some allocation carried over through June 1995, the expiration date of the first
catalog).

         In addition, virtually all of the start-up and development expenses
associated with IDT were similarly expensed. There are very few capitalized
development expenditures (other than those associated directly with the
acquisition of Oral Vision and Crown Systems) carried on the balance sheet.

         Liquidity and Capital Resources. As of March 31, 1995, the Company held
total assets of $12,512,119. Of these, $9,526,185 (76%) consisted of cash,
accounts receivable, inventories, and other current assets. As of this same
date, the Company had total liabilities of $6,481,034, with $5,757,297 of these
being current liabilities. The Company's current ratio at March 31, 1995 was
1.65, down slightly from 1.70 at the end of fiscal 1994. The debt to equity
ratio was 1.07, up from 0.84 at the end of fiscal 1994. These ratios,
specifically debt to equity, were affected by the net loss for the year.

           Cash and cash equivalents were $322,848 for fiscal 1995 compared to
$487,174 for fiscal 1994. Inventory increased from $4,869,402 at March 31, 1994
to $5,318,845 at March 31, 1995. This increase resulted primarily from the
Company's expansion of its product lines and to meet the higher level of sales
from fiscal 1994 to 1995.

         Accounts receivable increased only slightly from $2,125,679 at March
31, 1994 to $2,137,276 at March 31, 1995. Considering the increase in revenues
of $11,565,238 from fiscal 1994 to fiscal 1995, this slight increase in accounts
receivable reflects the Company's success in managing its credit and collection
efforts.


                                       35
<PAGE>   36
         Prepaid expenses and other current assets increased from $274,740 for
fiscal 1994 to $471,931 for fiscal 1995. The majority of this $197,191 increase
results from marketing and direct mailing expenditures which will benefit future
periods.

         Income taxes receivable was $565,720 as of March 31, 1995 compared to
$0 at March 31, 1994. The Company made estimated tax deposits based on interim
earnings in early fiscal 1995 and now expects a refund of $531,000. Also
included is a $34,720 overpayment on a prior year return.

         Property and equipment was $888,410 at March 31, 1995 compared to
$680,922 at March 31, 1994. Additions to property and equipment before current
year depreciation were approximately $470,000, with approximately $250,000
expended for Ryker Dental and the remainder for IDT. Ryker continued to expand
its computer system which accounts for a majority of their capital expenditures.
IDT acquired certain assets of Crown Systems, Inc. and the development of the
business during the fiscal year required capital investment into computer
systems, furniture and equipment and leasehold improvements. Accumulated
depreciation increased $224,362 during fiscal 1995.

         Assets of business transferred under contractual arrangements decreased
from $600,282 at March 31, 1994 to $490,518 at March 31, 1995. This decline
results from the receipt of principal payments made by DII on the Company's note
receivable.

         Intangible assets were $1,354,852 at March 31, 1995, compared to
$1,123,822 at March 31, 1994. The net increase of $231,030 resulted primarily
from the November 1, 1994 acquisition of certain assets and liabilities of Crown
Systems, Inc. This acquisition included certain software rights totaling
$275,981. Software rights are amortized using a five year amortization in
accordance with the Company's accounting policies.

         Deferred income taxes increased by $180,000 in fiscal 1995. This
increase relates to the tax benefit resulting from the current year operating
results.

         Accounts payable and accrued expenses increased from $3,967,991 at
March 31, 1994 to $4,303,907 at March 31, 1995. The $335,916 increase results
from an increase of inventory


                                       36
<PAGE>   37
attributable to the increased sales, and breadth of product line, and accrued
payroll and payroll related expenses for IDT as this business expanded during
fiscal 1995.

         Notes payable at March 31, 1995 totaled $2,034,000, of which $1,311,770
was classified as a current liability. Total notes payable at March 31, 1994
were $600,679, of which the entire amount was current. The increase of
$1,433,321 relates to expanded operations of IDT during fiscal 1995 and the
working capital requirement to develop the business.

         Deferred revenues were $125,035 at March 31, 1995, compared to $197,466
at March 31, 1994. Deferred revenues represent prepaid seminar fees from
customers and customer deposits or pre-payments on sales orders not yet
delivered or completed.

         Total stockholders' equity at March 31, 1995 was $6,031,085, which
represents an increase of $77,581 from March 31, 1994. Retained earnings
decreased $419,437 during fiscal 1995 as a result of operations. However, common
stock and capital contributed in excess of par value increased $497,018 during
fiscal 1995. The majority of the increase came from a sale of the Company's
restricted common stock in a private placement.

         In accordance with generally accepted accounting principles, the
balance sheet does not reflect the future interest and royalty income which
Bio-Dental contractually receives from DII, its former manufacturing subsidiary.
This royalty was a monthly minimum of $30,000 for the year ended March 31, 1994
and from April through December 1994. Effective January 1995, the monthly
minimum royalty payment increased to $43,000 per month. However, actual royalty
payments continued to be higher than the minimum requirements.

         If the Company were to repeatedly have losses similar to that which it
experienced in the fourth quarter of fiscal 1995, the Company could run into
liquidity problems and eventually have difficulty meeting its credit
obligations.

         Debt Financing. In December 1992, the Company secured a $1 million line
of credit from The Bank of California. In December 1993, this line was expanded
to $1.5 million and in August 1994, the line was expanded to $3 million. In
addition to the line of credit, a $1 million term note with the bank was secured
in March


                                       37
<PAGE>   38
1995. The line expires August 25, 1995 and the note is due on May 1, 1998 with
monthly principal payments of $27,777 beginning June 1, 1995. The line and note
bear interest at prime plus 0.75% with an option at the Company's discretion to
allocate part of the line balance to a fixed rate for short periods of time. The
line and note are secured by the inventories, accounts receivable and various
other assets of the Company.

         The Company has used this line of credit for working capital to finance
its growth, specifically in information systems and in IDT. The note was used
primarily to fund the retirement of existing debt associated with the
acquisitions of Ryker, Oral Vision and Crown Systems.

         The Company's debt agreements contain various covenants regarding
working capital, net worth and profitability, among other items. At March 31,
1995, the Company was not in compliance with the covenants regarding
profitability and debt to tangible net worth ratio, but received a waiver and
modification on those covenants from The Bank of California on July 12, 1995.
The Bank of California also modified the tangible net worth and working capital
requirements on July 12, 1995.


         Proposed Mergers, Acquisitions or Divestitures.

         Denticator International, Inc. On May 10, 1996, the Company signed a
letter of intent with Young Innovations, Inc. which contemplates Young's buy out
of the Company's rights to receive royalties through March 1999 from Denticator
International, Inc. (DII) for a lump sum cash payment of $7.5 million.
Denticator, a former subsidiary of Bio-Dental, was sold in 1991, and since that
time Bio-Dental has been receiving royalties from Denticator. The Company
estimates that the $7.5 million payment approximates the net-present-value of
Bio-Dental's projected future royalties, including a scheduled lump-sum payment
that would have been due in April 1999.

         The letter of intent is part of a transaction in which Denticator
International Inc., will be acquired by Young Innovations, Inc., located in
Earth City, Missouri. The transaction is subject to due diligence and other
contingencies and is scheduled to close by the end of July 1996.


                                       38
<PAGE>   39
         The sale of these royalty payments will significantly strengthen the
Company's balance sheet. The Company anticipates that the transaction will
eliminate all of its currently outstanding bank debt and notes payable, and
provide the Company with additional cash.

         Zila, Inc. On May 31, 1996 The Company signed a letter of intent to
merge Bio-Dental into Zila, Inc. The transaction will involve the exchange of
Zila stock for all of Bio-Dental's outstanding stock. Zila's acquisition of
Bio-Dental is subject to a number of conditions, including satisfactory
completion of due diligence by both companies, execution of definitive
agreements, the ability to account for the transaction as a
pooling-of-interests, and the approval of Bio-Dental's shareholders.

        The terms of the letter of intent call for Zila to exchange between
0.75 and 0.825 shares of its stock for each of Bio-Dental's 6.4 million shares,
with the actual rate to be based upon the average closing bid prices of Zila's
stock during the ten (10) day "calculation period" ending on the trading date
that is five trading days prior to the closing date. In no event, however, will
Zila issue less than $4.95 worth of its stock for each share of Bio-Dental.

         If Zila's stock averages between $6 and $7.75 during the valuation
period, then the exchange rate will be 0.825:1. If Zila's stock averages over
$8.52, then the exchange rate shall be 0.75:1. If Zila's stock averages between
$7.75 and $8.25 during the valuation period, then Zila will issue that
fractional number of shares necessary to provide each Bio-Dental share with
$6.39 worth of Zila stock. If Zila's stock averages below $6.00 during the
valuation period, then Zila shall issue that number of shares necessary to
provide $4.95 per share of value for each share of Bio-Dental. The table below
illustrates the above information:

         Zila, headquartered in Phoenix, Arizona, markets a rapidly growing line
of non-prescription oral health care products, and is introducing what the
Company believes to be the first oral cancer diagnostic, OraTest(TM). FDA
approval to market OraTest in the U.S. is pending.

         OraTest is a patented, inexpensive, highly accurate diagnostic adjunct
used to examine patients at high risk of oral cancer -- those 40 and over who
use tobacco or drink heavily. According to Zila, clinical studies have shown
OraTest to be highly sensitive for detecting squamous cell carcinoma. It is also
used to delineate sites for biopsy and surgery, and has proven to be a highly
effective smoking cessation counseling tool.

         The Company will become the exclusive distributor of OraTest in the
U.S. when regulatory approval is granted. As the exclusive distributor of
OraTest, the Company anticipates that it will have the opportunity to
significantly expand its market share by cross-selling other dental supplies to
new OraTest customers.

         Oral cancer is reportedly the eighth most common form of cancer in the
U.S. and Europe, with approximately 30,000 new cases diagnosed each year,
accounting for approximately 8,000 deaths.

         OraTest is a simple solution that the patient gargles with, causing any
cancerous lesions to be stained an almost-florescent blue color so they can be
easily identified.

         It is currently contemplated that management for both companies will
remain in place, and the Company does not believe that any material personnel
changes will occur as a result of this merger. Zila will continue to run their
existing operations out of Phoenix and Bio-Dental will continue to run its
operations out of its existing facilities. No definitive changes in employee
benefits have been identified.

         It is anticipated that the merger will be consummated during the third
quarter of the current fiscal year following Bio-Dental


                                       40

Shareholder approval of the proposed merger. Until that time Bio-Dental, will
continue its normal business operations.

Board of Directors and Stockholders
BIO-DENTAL TECHNOLOGIES CORPORATION AND SUBSIDIARIES

We have audited the accompanying consolidated balance sheet of BIO-DENTAL
TECHNOLOGIES CORPORATION AND SUBSIDIARIES as of March 31, 1996 and the related
consolidated statements of operations, stockholders' equity and cash flows for
the years ended March 31, 1996 and 1995. 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 financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Bio-Dental
Technologies Corporation and Subsidiaries as of March 31, 1996 and the
consolidated results of their operations and their consolidated cash flows for
the years ended March 31, 1996 and 1995 in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                             March 31, 1996 and 1995



NOTE A - ORGANIZATION AND NATURE OF BUSINESS

   Bio-Dental Technologies Corporation (the Company) was incorporated April 5,
   1988. The Company is a dental products marketing organization which sells
   professional dental products nationally through the operations of two
   wholly-owned subsidiaries. Ryker Dental of Kentucky, Inc., (Ryker) markets
   consumable dental merchandise and supplies and equipment via telemarketing
   and catalog sales under the trade name "The Supply House." The Company's
   other subsidiary, Integrated Dental Technologies, Inc., (IDT) markets
   high-technology dental products such as intra-oral cameras and practice
   software to dentists.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   1. Principles of consolidation

   The consolidated financial statements include the accounts of the Company and
   its wholly owned subsidiaries. All significant intercompany balances and
   transactions have been eliminated.

   2. Use of estimates

   In preparing financial statements in conformity with generally accepted
   accounting principles, management makes estimates and assumptions that affect
   the reported amounts of assets and liabilities and disclosures of contingent
   assets and liabilities at the date of the financial statements, as well as
   the reported amounts of revenues and expenses during the reporting period.
   Actual results could differ from those estimates.

   3. Cash and cash equivalents

   For purposes of the statements of cash flows, the Company considers all
   highly liquid debt instruments purchased with a maturity of three months or
   less to be cash equivalents.

   4. Inventories

   All Company inventories are valued at the lower of cost or market. The
   Company utilizes a method which approximates first in - first out to
   determine cost.

   5. Property and equipment

   Property and equipment are stated at cost. Depreciation is computed using the
   straight line method over the estimated useful lives of the assets ranging
   from two to ten years. Leasehold improvements are amortized over the lease
   term or the estimated useful life, whichever is shorter.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

   6. Intangible assets

   Intangible assets consist of goodwill, software rights, organizational costs,
   and covenants not to compete. All intangible assets are amortized on a
   straight line basis. Organizational costs and goodwill are being amortized
   over 20-40 years and covenants are amortized over the term of the agreement.
   Software rights are being amortized over five years. On an ongoing basis,
   management reviews the valuation and amortization of intangible assets. As
   part of this review, the Company estimates the value and future benefits of
   the cash flows generated by the related subsidiaries to determine whether
   impairment has occurred.

   7. Income taxes

   The Company utilizes an asset and liability approach in accounting for income
   taxes. This approach requires the recognition of the deferred tax liabilities
   and assets for the expected future tax consequences of temporary differences
   between the financial statement carrying amounts and tax basis of assets and
   liabilities. Deferred tax assets and liabilities are reflected at currently
   enacted income tax rates applicable to the period in which the deferred tax
   assets or liabilities are expected to be realized or settled. As changes in
   tax laws or rates are enacted, deferred tax assets and liabilities are
   adjusted through the provision for income taxes.

   8. Loss per share

   Loss per share is based upon the weighted average number of common shares
   outstanding.

   9. Financial instruments

   The carrying amounts of financial instruments, including cash, accounts
   receivable, accounts payable, assets of business transferred under
   contractual arrangements, and notes payable approximated fair value as of
   March 31, 1996 because of the relatively short maturity of these instruments.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

   10. Stock-based compensation

   The Company grants stock options for a fixed number of shares to employees
   with an exercise price equal to the fair value of the shares at the date of
   grant. The Company accounts for stock option grants in accordance with
   Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
   Employees. That opinion requires that compensation cost related to fixed
   stock option plans be recognized only to the extent that the fair value of
   the shares at the grant date exceeds the exercise price. Accordingly, the
   Company recognizes no compensation expense for its stock option grants.

   11. Future effect of recently issued accounting pronouncement

   In March 1995, the Financial Accounting Standards Board issued Statement of
   Financial Accounting Standards 121, Accounting for the Impairment of
   Long-Lived Assets and for Long-Lived Assets to Be Disposed Of (SFAS 121).
   SFAS 121 requires that long-lived assets and certain identifiable intangibles
   held and used by an entity be reviewed for impairment whenever events or
   changes in circumstances indicate that the carrying amount of an asset may
   not be recoverable. If the sum of the expected future cash flows
   (undiscounted and without interest) is less than the carrying amount of the
   asset, an impairment loss is recognized. Measurement of that loss would be
   based on the fair value of the assets. SFAS 121 also generally requires
   long-lived assets and certain identifiable intangibles to be disposed of, to
   be reported at the lower of the carrying amount or the fair value less cost
   to sell. SFAS 121 is effective for the Company's 1997 fiscal year end. The
   Company has made no assessment of the potential impact of adopting SFAS 121
   at this time.


NOTE C - ACCOUNTS RECEIVABLE

   Accounts receivable consist of the following at March 31, 1996:

         Accounts receivable, net                            $1,973,943

</TABLE>

   Financial instruments which potentially subject the Company to credit risk
   consist principally of trade receivables. The Company provides credit, in the
   normal course of business, to dentists. The Company performs ongoing credit
   evaluations of its customers and maintains an allowance for potential credit
   losses. IDT sales are generally transacted on a pre-approved, lease, credit
   card, or prepaid basis, thereby minimizing credit risk.

NOTE D - INVENTORY

   Ryker inventory includes consumable dental products and supplies as well as
   dental equipment. IDT inventory includes intra-oral cameras, their
   components, filmless x-rays and computer hardware. Due to a restructuring
   (note P), the Company will no longer sell the filmless x-ray or computer
   hardware. As a result of this restructuring, a writedown of approximately
   $300,000 has been made to the related inventory. An unrelated writedown of
   approximately $300,000 has been made for potentially obsolete intra-oral
   cameras. The writedown was due to the introduction of a new intra-oral
   camera.

   Inventory balances as of March 31, 1996 are as follows:

   Certain financial covenants with which the Company was not in compliance as
   of March 31, 1996 were waived by the Bank until April 1, 1996. The bank has
   the right to make all principal and interest on the loans immediately due and
   payable as the result of noncompliance with the covenants. The Company's
   future ability to comply with such covenants is uncertain. However, the
   Company expects that the sale of Denticator International, Inc. (note K) will
   result in compliance with the covenants.

NOTE K - ASSETS OF BUSINESS TRANSFERRED UNDER CONTRACTUAL ARRANGEMENTS (NOTE 
         RECEIVABLE)

   In March 1991, the Company incorporated a wholly owned subsidiary, Denticator
   International, Inc. (DII) and transferred the Company's manufacturing
   operations into DII in exchange for the issuance of a $600,282 note to the
   Company with monthly principal payments of $10,005 plus interest at 150% of
   the Company's cost of funds from April 1, 1994 through March 31, 1999.
   Interest only payments were made from March 1991 through March 31, 1994.
   Effective with the date of incorporation, the Company entered into a
   licensing agreement with DII for the manufacture and sale of certain dental
   products owned by the Company. Under this agreement, DII will pay the Company
   a monthly royalty equal to the greater of $30,000 or 17% of net sales of DII.
   In addition, the agreement provides for further royalties to be paid to the
   Company if DII achieves certain levels of profitability.

   On March 31, 1991, the Company sold all of the outstanding capital stock of
   DII to DII's former operations manager. The sales agreement incorporated the
   licensing agreement described above.

   Effective April 1, 1994, the licensing agreement was amended. The terms
   included herein reflect all amendments. In March 1999, DII has the option to
   purchase the rights under this licensing agreement. The purchase price is
   equal to the greater of 1.5 times average annual sales of DII during the
   period covered by the amended agreement (April 1, 1994 - March 31, 1999) or
   six times the average pre-tax income of DII after certain adjustments. The
   purchase price will be reduced by 50% of the additional royalties paid by DII
   between April 1, 1994 and March 31, 1999.

   During the year ended March 31, 1995, the Company earned royalties under the
   DII licensing agreement totaling $1,665,699, which is included in royalty
   revenue, and interest on the note payable totaling $69,418, which is included
   in interest and other income. DII paid the Company $58,652 in lease payments
   for equipment leased by DII from the Company. Effective January 1995, DII
   increased the minimum monthly royalty to the Company to $43,000 per month in
   exchange for the Company waiving the provision in the agreement whereby the
   Company could purchase products made by DII at specified prices. At March 31,
   1995, DII owed $312,263 in royalties and interest to the Company. The Company
   purchased products from DII amounting to $142,480 during the fiscal year and
   owed DII $1,004 at March 31, 1995.

   During the year ended March 31, 1996, the Company earned royalties under the
   DII licensing agreement totaling $1,408,671, which is included in royalty
   revenue, and interest on the note payable totaling $72,178, which is included
   in interest and other income. At March 31, 1996 DII owed the Company $424,690
   in royalties and interest. The Company purchased products from DII amounting
   to $364,899 during the fiscal year and owed DII $2,741 at March 31, 1996.

NOTE K - ASSETS OF BUSINESS TRANSFERRED UNDER CONTRACTUAL ARRANGEMENTS (NOTE 
         RECEIVABLE) - CONTINUED

   The Company continues to guarantee DII's lease for its office and warehouse
   space due to the fact that DII was a wholly-owned subsidiary of the Company
   at the time this contract was originated, and the lessor is unwilling to
   release the guarantee.

   On May 10, 1996 the Company signed a letter of intent to sell the DII
   licensing agreement to Young Innovations, Inc. (Young) for approximately $7.5
   million in cash. Young will also issue to the Company a credit against future
   purchases in the amount equal to all accrued royalties and notes payable by
   DII to the Company as payment for such items. As of the closing date, the
   Company will cancel 50,000 Company stock options that are currently held by
   DII. The transaction is subject to due diligence, and the obtaining of bank
   financing by Young.

   are authorized to be issued.

NOTE M - BENEFIT PLAN

   The Company adopted an Employee Stock Ownership Plan (ESOP) during the fiscal
   year ended March 31, 1991. The benefits allocated to each participant are in
   direct proportion to that person's annual compensation. All employees who
   meet the following criteria are eligible for benefits: (1) must be 18 years
   of age or older; (2) must have worked at least 1,000 hours in the given plan
   (fiscal) year; and (3) must be employed on the last day of the plan year. All
   participants become fully vested after 5 years of continuous employment with
   the Company.

   Once vested, a person may receive benefits under the plan:

         A)   No later than 6 years from the date of termination of employment 
              with the Company; or

         B)   Upon reaching the age of 60.

NOTE N - ACQUISITION OF CROWN SYSTEMS ASSETS AND LIABILITIES

   On November 14, 1994, the Company signed an agreement and purchased the
   assets and certain liabilities of Crown Systems, Inc. (Crown), effective
   November 1, 1994. In connection with this purchase, the Company issued 36,191
   shares of its previously unissued restricted common stock to Crown. The
   assets acquired consisted mainly of accounts receivable and dental practice
   management software rights. As part of the transaction, the Company retired
   approximately $205,000 of assumed liabilities. On October 25, 1995, the
   Company issued an additional 11,310 shares of restricted common stock to the
   previous owners of Crown due to a change in the calculated purchase price.

   The transaction was accounted for as a purchase. The depreciable assets
   acquired are being depreciated over their remaining useful lives on a
   straight line basis, in accordance with the Company's accounting policies.
   The software rights which were acquired are being amortized over a period of
   five years. The assets and liabilities are held in Integrated Dental
   Technologies, Inc., a wholly-owned subsidiary of the Company.

NOTE N - ACQUISITION OF CROWN SYSTEMS ASSETS AND LIABILITIES - CONTINUED

   Crown develops and markets dental practice management software systems and
   will continue to develop additional software for IDT. As part of the

   agreements and three year non-compete agreements with IDT.

 NOTE O - WARRANTS TO PURCHASE RESTRICTED COMMON STOCK

   In connection with certain capital financing activities during the years
   ended March 31, 1991 and 1992, the Company issued 350,000 stock purchase
   warrants at $2.25 to $3.11 per share. As a result of a cashless exercise of
   200,000 warrants, 96,333 shares were issued at $3.11 on April 20, 1994. The
   remaining warrants expire in August 1997, unless sooner exercised.

   Options to purchase 50,000 shares of the Company's restricted common stock
   were issued to DII in connection with the amendments to the licensing
   agreement, as described in note K. These options expire on the earlier of
   March 31, 2004, or upon closing of the DII sale described in note K.

 NOTE P - RESTRUCTURING

   During the quarter ending March 31, 1996, the Company recorded a charge of
   $271,631 for the restructuring of IDT. As a result of the restructuring, IDT
   no longer sells computer hardware or filmless x-ray systems. Costs included
   in the restructuring charge include contract costs and other costs. These
   costs involve the use of estimates as described in note B. The Company
   expects that the liabilities associated with such costs will be paid or
   settled within the next fiscal year.

   As a result of management's decision to restructure its operations,
   approximately $300,000 of inventory was written off to cost of products sold
   and management reserved approximately $250,000 for sales returns related to
   these discontinued items. Total restructuring charges, inventory writedowns,
   and return reserves amount to approximately $822,000.

   On March 29, 1996, the Company signed term notes in the aggregate principal
   amount of $1,250,000. As additional consideration for the term notes, the
   Company issued 250,000 warrants to purchase the common stock of the Company
   at an initial exercise price of $3.03 per share. In conjunction with the
   transaction, the Company paid to a third-party, a placement fee of $100,000
   and issued warrants to purchase 50,000 shares of the Company's stock at an
   initial exercise price of $3.03 per share. The transaction was completed on
   April 1, 1996, when the purchasers of the notes transferred cash to the
   Company.

   The notes bear interest at a rate of 12%. Accrued interest is due on
   September 30, 1996 and March 31, 1997. Thereafter, interest is due on a
   quarterly basis. Principal is due on the earliest of (i) March 29, 1997, or
   (ii) the disposition of either or both of (A) the Company's Supply House
   division or (B) the Company's royalty rights from Denticator, or (iii) a
   disposition of the Company.

   An additional 27,778 warrants to purchase Company stock at an initial
   exercise price of $3.03 per share will be issued to the purchasers of the
   notes on a monthly basis beginning July 31, 1996, for each month in which the
   principal and accrued interest on the term notes is not repaid in full. The
   purchase price and number of shares purchasable upon exercise of warrants may
   be adjusted upon the occurrence of certain events. The maximum number of
   warrants issued to the purchasers of the notes is 500,000. The warrants
   expire on the earlier of (i) March 29, 2001, or (ii) the closing of a
   consolidation or merger of the Company with or into another corporation or a
   sale of all or substantially all of the assets of the Company.

 NOTE R - PROPOSED MERGER

   On May 31, 1996, the Company signed a letter of intent to merge into Zila,
   Inc. (Zila), a marketer of non-prescription oral healthcare products. Zila
   will exchange no less than 0.75 and no more than 0.825 shares of its common
   stock for each share of the Company's common stock, with the final rate to be
   based upon the price at which Zila's stock trades during the "calculation
   period" preceding the close of the transaction. The transaction is subject to
   the completion of due diligence by both parties, execution of a definitive
   agreement, the ability to account for the transaction as a
   pooling-of-interests, and Company shareholder approval.

 NOTE S - CONTINGENT LIABILITY

   In July 1995, the Company was named as a defendant, along with the Company's
   transfer agent and a shareholder of the Company (Shareholder), in a lawsuit.
   The lawsuit alleges that the Company wrongfully failed to register 200,000
   Company 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.

   The Company denies all of the material allegations of the lawsuit against it
   and asserts various affirmative defenses. The Company will vigorously defend
   against the claims set forth in the lawsuit. Nonetheless, there is a
   reasonable possibility that the Company will sustain a loss in this matter,
   estimated in a range from $320,000 to $1,250,000, or the re-issuance of
   200,000 shares of the Company's common stock. However, because of the
   inherent uncertainties associated with litigation and other factors, no
   accrual for a loss contingency has been made in the financial statements for
   the year ended March 31, 1996.

         Insurance Policy as Collateral dated "December 22", as acknowledged by

         identified above are hereinafter collectively referred to as the

D.       LOAN DOCUMENTS. The following documents evidence Borrower's obligations

<PAGE>   2
         upon execution, the Replacement Revolving Credit Note, the
         Subordination Agreement and the escrow assignment documents described
         in Section 3.2 below. The documents described above, to-ether with any
         other documents executed by or among the parties in connection with the
         Liabilities, and any and all amendments and modifications thereto, are
         referred to collectively in this Agreement as "Loan Documents". There
         are no written or oral agreements concerning or affecting the
         Liabilities between Borrower and/or Guarantors on the one hand and Bank
         on the other, other than the Loan Documents. Unless otherwise defined
         herein, all capitalized terms shall have the meanings assigned to them
         in the Loan Documents.

E.       DEFAULT. Based upon the information that Borrower has provided to Bank,
         Bank is aware that Borrower is and has been in default under the Notes
         as follows: (i) The Revolving Note matured on February 26, 1996, on
         which date all sums outstanding thereunder were due and payable in
         full, and Borrower has failed to pay these sums by said date. (ii)
         Failure to pay sums owed under the Revolving Note is also an event of
         default under the Term Note. (iii) In addition, Borrower has failed to
         satisfy minimum Tangible Net Worth and minimum working capital
         requirements established in the Credit Agreement. The foregoing
         defaults are collectively referred to hereinafter as the "Designated
         Defaults." Borrower and Guarantors each acknowledge that it has
         received adequate and reasonable notice of the Designated Defaults from
         Bank. Upon execution of this Agreement, Bank agrees to waive the
         Designated Defaults identified in (iii) above, and Bank further agrees
         that Borrower shall not be required to comply with these two financial
         covenants, as modified by this Agreement, until April 1, 1996 and
         thereafter. Borrower and Guarantor acknowledge that, except as
         expressly provided above, Bank has not waived any of its rights with
         respect to any breach by Borrower of any Loan Documents.

F.       BANK'S DEFAULT RIGHTS. Because of the existence of the Designated
         Defaults, Bank has no obligation to make any further Advances under the
         Revolving Note and has advised the Borrower that no such Advances are
         available until due execution of this Agreement. Bank also has the
         current right to exercise any and all of its other rights and remedies
         against Borrower, Guarantors or otherwise under applicable law and the
         Loan Documents. Such remedies include, without limitation, the right to
         charge interest at the post-default or postmaturity rate established in
         the other Loan Documents and to foreclose upon the Collateral.

G.       EXTENSION/MODIFICATION. At Borrower's and Guarantors' request, Bank is
         willing to modify the Loan Documents as set forth herein, provided that
         the conditions set forth herein are satisfied within the time periods
         required under this Agreement. Borrower has represented to Bank that it
         and Jose Mendoza are actively pursuing the sale of Denticator
         International, Inc. ("Denticator"), a corporation wholly owned by
         Mendoza. Borrower has represented to Bank that Borrower is
         contractually entitled to certain of the proceeds of the sale of
         Denticator, and that such sums will be paid to Borrower concurrently
         with the completion of such sale. Borrower has represented to Bank that
         Borrower will use such proceeds received by Borrower from the sale of
         Denticator to repay the Liabilities in full.

                                    AGREEMENT

NOW THEREFORE, in consideration of the foregoing and for other valuable
consideration, the receipt and sufficiency of which are hereby acknowledged

6. REPRESENTATIONS AND WARRANTIES. To induce Bank to enter into this Agreement
each of Borrower and Guarantors hereby represents and warrants to Bank as
follows:

         6.1 REPRESENTATIONS AND WARRANTIES TRUE AND CORRECT; SURVIVAL. All
         representations and warranties contained in this Agreement and in any
         and all of the other Loan Documents are true and correct as of the date
         of this Agreement, and all such representations and warranties shall
         survive the execution of this Agreement;

         6.2 NO VIOLATION. The execution, delivery and performance by Borrower
         and Guarantors of this Agreement and all documents contemplated
         hereunder are within Borrower's and each powers, have been duly
         authorized, and are not in conflict with Borrower's or any Guarantor's
         articles of incorporation or bylaws, or the terms of any charter or
         other organizational document of Borrower or any Guarantor; and all
         such documents constitute valid and binding obligations of Borrower and
         each respective Guarantor, enforceable in accordance with their terms.
         In addition, such execution, delivery and performance by Borrower and
         each Guarantor will not violate any law, rule or order of any court or
         governmental agency or body to which Borrower or any Guarantor is
         subject; and cannot (except as expressly provided or contemplated
         herein) result in the creation or imposition of any lien, security
         interest or encumbrance on any now owned or hereafter acquired property
         of Borrower or any Guarantor;

         6.3 NO BREACH. With the exception of the Designated Defaults, no event
         has occurred or failed to occur that is, or, with notice or lapse of
         time or both would constitute A default, an event of default, or a
         breach or failure of any condition under any Loan Document;

         6.4 UNCONDITIONAL OBLIGATION; NO DEFENSES. Each of the Notes represents
         an unconditional, absolute, valid and enforceable obligation against
         Borrower. Borrower has no claims or defenses against Bank or any other
         person or entity which would or might affect (a) the enforceability of
         any provisions of the Loan Documents or (b) the collectability of sums
         advanced by Bank in connection with the Liabilities. Borrower
         understands and acknowledges that the Bank is entering into this
         Agreement in reliance upon, and in partial consideration for, this
         acknowledgment and representation, and agrees that such reliance is
         reasonable and appropriate.

7. BORROWER'S AND GUARANTORS' COVENANTS. Unless Bank otherwise consents in
writing during remaining term of the Notes, each of Borrower and Guarantors will
do the following:

         7.1 Comply with all requirements of all Loan Documents to the extent
         not inconsistent with this Agreement:

         7.2 Not enter into any agreements with any of its other creditors that
         might impair its ability to perform under this Agreement. Borrower
         shall promptly provide the Bank copies of any and all such agreements
         that Borrower may have entered into before the date of this Agreement
         and any agreements with any other creditor that may constitute such an
         agreement that Borrower may enter into during the term of the Notes.

         7.3 Pay on a current basis all of its other creditors for indebtedness
         incurred during the term of the Notes.

<PAGE>   6
         7.4 Ensure that Bank is fully informed at all times of all matters
         relating to the operation of Borrower's business, including any planned
         changes in key personnel or manner of operating its business.

         7.5 Take any and all actions of any kind or nature whatsoever, either
         directly or indirectly, that are necessary to prevent Bank from
         suffering a loss with respect to the Liabilities or being deprived of
         the Collateral or of any rights or remedies of Bank with respect to the
         Loan, the Loan Documents or this Agreement in the event of a default by
         Borrower under this Agreement or any other Loan Documents (or the
         ability to exercise such any rights or remedies.

8. ADDITIONAL EVENTS OF DEFAULT. In addition to the events of default set forth
in the Loan Documents, the occurrence of any of the following events of default
other than a Designated Default shall be an event of default and, at Bank's
option, may make all obligations of Borrower immediately due and payable, all
without demand, presentment or notice, all of which requirements Borrower hereby
waives:

         8.1 SALE OF BUSINESS. The sale of part or all of Borrower, RDK, IDT
         and/or Denticator, or the sale of a material part of the assets of any
         of the foregoing;

         8.2. FAILURE TO PERFORM. Failure to perform any of the obligations set
         forth in this Agreement or in any other Loan Documents (as the same may
         be modified by this Agreement);

         8.3 REPRESENTATIONS AND WARRANTIES. Any representation or warranty of
         Borrower or Guarantors herein or in any other Loan Document shall be
         false, misleading or incorrect;

         8.4 MATERIAL ADVERSE CHANGES. If there is any further substantial
         impairment of the prospect of Borrower's satisfaction of its
         obligations to Bank or substantial impairment of the value of the
         Collateral or any substantial impairment of the priority of Bank's
         security interest in or lien on any Collateral or if there is any
         substantial impairment of the ability of any Guarantor to perform under
         its respective Guaranty.

9. REMEDIES. Upon the occurrence of an event of default and at all times
thereafter, Bank, without the necessity of obtaining any prior approval of any
court, shall be entitled to (a) terminate all Advances under the Revolving Note;
(b) return any and all checks drawn against Borrower's account at Bank upon
payment of all checks issued prior to the occurrence of such event of default,
(c) apply all funds in Borrower's account at Bank to Liabilities; and (d)
exercise in respect of any Collateral it may hold all rights and remedies of a
secured creditor available to it under applicable laws, and Bank shall also be
entitled to exercise all rights and remedies available to Bank as a creditor
generally, including without limitation all remedies available to Bank under the
Loan Documents, as well as rights and remedies available to Bank at law or in
equity. All such rights and remedies shall be cumulative. No failure or delay on
the part of Bank in exercising any power, right or remedy under any of the Loan
Documents shall operate as a waiver thereof, and no single or partial exercise
of any such power, right or remedy shall preclude any further exercise thereof
or the exercise of any other party, right or remedy.

10. RELEASE. Borrower and each Guarantor each hereby, for itself, its
successors, heirs, executors, administrators and assigns, releases, acquits and
forever discharges Bank, its directors, officers, employees, agents, affiliates,
successors, administrators and assigns ("Released Parties") of and from any and
all claims, actions, causes of action, demands, rights, damages, costs, loss of
service, expenses and compensation whatsoever which Borrower or any Guarantor,
or both, might have because of anything done, omitted to be done, or allowed to
be done by any of Released Parties and in any way connected with the Liabilities
or this Agreement or the other Loan Documents as of the date of execution of
this Agreement, WHETHER KNOWN OR UNKNOWN, FORESEEN OR UNFORESEEN, including
without limitation, any specific claim raised by Borrower and/or any Guarantor,
and also including without limitation any settlement negotiations and also
including without limitation, any damages


                                        6
<PAGE>   7
and the consequences thereof resulting or to result from the events described,
referred to or inferred hereinabove ("Released Matters"). Borrower and each
Guarantor each further agrees never to commence, aid or participate in (except
to the extent required by order or legal process issued by a court or
governmental agency of competent jurisdiction) any legal action or other
proceeding based in whole or in part upon the foregoing. In furtherance of this
general release, Borrower and each Guarantor each acknowledges and waives the
benefits of California Civil Code section 1542 (and all similar ordinances and
statutory, regulatory, or judicially created laws or rules of any other
jurisdiction), which provides:

"A general release does not extend to claims which the creditor does not know or
suspect to exist in his favor at the time of executing the release, which if
known by him must have materially affected his settlement with the debtor."

Borrower and each Guarantor each agrees that this waiver and release is an
essential and material term of this Agreement and that the agreements in this
paragraph are intended to be in full satisfaction of any alleged injuries or
damages in connection with the Released Matters. Borrower and each Guarantor
each represents and warrants that it has not purported to convey, transfer or
assign any right, title or interest in any Released Matter to any other person
or entity and that the foregoing constitutes a Ml and complete release of the
Released Matters. Borrower and each Guarantor also understands that this release
shall apply to all unknown or unanticipated results of the transactions and
occurrences described above, as well as those known and anticipated. Borrower
and each Guarantor each has consulted with legal counsel prior to signing this
release, or had an opportunity to obtain such counsel and knowingly chose not to
do so, and executes such release voluntarily, with the intention of fully and
finally extinguishing all Released Matters.

11.      DISPUTE RESOLUTION.

         11.1 MANDATORY MEDIATION/ARBITRATION. Any controversy or claim between
         or among the parties, their agents, employees and affiliates, including
         but not limited to those arising out of or relating to this Agreement
         or any related agreements or instruments ("Subject Documents"),
         including without limitation any claim based on or arising from an
         alleged tort, shall, at the option of any party, and at that party's
         expense, be submitted to mediation, using either the American
         Arbitration Association ("AAA") or Judicial Arbitration and Mediation
         Services, Inc. ("JAMS"). If mediation is not used, or if it is used and
         it fails to resolve the dispute within 30 days from the date AAA or
         JAMS is engaged, then the dispute shall be determined by arbitration in
         accordance with the rules of either JAMS or AAA (at the option of the
         party initiating the arbitration) and Title 9 of the U. S. Code,
         notwithstanding any other choice of law provision in the Subject
         Documents. All statutes of limitations or any waivers contained herein
         which would otherwise be applicable shall apply to any arbitration
         proceeding under this subparagraph 11.1. The parties agree that related
         arbitration proceedings may be consolidated. The arbitrator shall
         prepare written reasons for the award. Judgment upon the award rendered
         may be entered in any court having jurisdiction. This subparagraph 11.1
         shall apply only if, at the time of the proposed submission to AAA or
         JAMS, none of the obligations to Bank described in or covered by any of
         the Subject Documents are secured by real property collateral or, if so
         secured, all parties consent to such submission.

         11.2 JURY WAIVER/JUDICIAL REFERENCE. If the controversy or claim is not
         submitted to arbitration as provided and limited in subparagraph I 1.
         1, but becomes the subject of a judicial action, each party hereby
         waives its respective right to trial by jury of the controversy or
         claim. In addition, any party may elect to have all decisions of fact
         and law determined by a referee appointed by the court in accordance
         with applicable state reference procedures. The party requesting the
         reference procedure shall ask AAA or JAMS to provide a panel of retired
         judges and the court shall select the referee from the designated
         panel. The referee shall prepare written findings of fact and
         conclusions of law. Judgment upon the award rendered shall be entered
         in the court in which such proceeding was commenced.


                                        7
<PAGE>   8
         11.3 PROVISIONAL REMEDIES, SELF HELP, AND FORECLOSURE. No provision of,
         or the exercise of any rights under, subparagraph I 1. I shall limit
         the right of any party to exercise self help remedies such as setoff,
         to foreclose against any real or personal property collateral, or to
         obtain provisional or ancillary remedies such as injunctive relief or
         the appointment of a receiver from a court having jurisdiction before,
         during or after the pendency of any mediation or arbitration. At Bank's
         option, foreclosure under a deed of trust or mortgage may be
         accomplished either by exercise of power of sale under the deed of
         trust or mortgage, or by judicial foreclosure. The institution and
         maintenance of an action for judicial relief or pursuit of provisional
         or ancillary remedies or exercise of self help remedies shall not
         constitute a waiver of the right of any party, including the plaintiff,
         to submit the controversy or claim to mediation or arbitration.

         11.4 CONFLICT. To the extent any provision of the dispute resolution
         clause is different than the terms of this Agreement, the terms of this
         dispute resolution clause shall prevail.

12. WAIVER OF STATUTE OF LIMITATIONS. Borrower and each Guarantor each shall not
plead the statute of limitations to any action brought by Bank with respect to
the Liabilities, Notes, Credit Agreement, Guaranties, Security Agreements and
any other Loan Document, and the Collateral, and hereby waives the statute of
limitations in respect of any and all sums due from it under the Notes.

13. CONFIRMATION OF GUARANTIES; UNCONDITIONAL OBLIGATIONS; WAIVER. Each
Guarantor reaffirms its obligations under its Guaranty and reaffirms and
restates each and every term, condition, and provision of its Guaranty. In
addition each, Guarantor hereby agrees that its obligations under its Guaranty
shall be unconditional, irrespective of (i) the absence of any attempt to
collect the Liabilities from Borrower or any other guarantor or other action to
enforce the same, (ii) the waiver or consent by Bank with respect to any
provision of any instrument evidencing the Liabilities, or any part thereof, or
any other agreement now or hereafter executed by Borrower and delivered to Bank,
(iii) Bank's election, in any proceeding instituted under Chapter 11 of Title 1
of the United States code (11 U.S.C. Section101 et seq.) (the "Bankruptcy
Code"), of the application of Section 111l(b)(2) of the Bankruptcy Code, (iv)
any borrowing or grant of a security interest by Borrower, as
debtor-in-possession, under Section 364 of the Bankruptcy Code, or (v) the
disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of
Bank's claim(s) for repayment of the Liabilities. Each Guarantor further
reaffirms that its obligations under its Guaranty are primary and are separate
and distinct from Borrower's obligations. Each Guarantor further represents and
warrants that it has no defenses or claims against Bank that would or might
affect the enforceability of its Guaranty and that its Guaranty remains in full
force and effect. Each Guarantor irrevocably and permanently (even if such
Guarantor pays said obligations in full) waives any and all rights of
subrogation, reimbursement indemnity, contribution or any other claim arising
from the existence of performance of its Guaranty which Guarantor may now or
hereafter have against Borrower or any other Person (or their respective
properties) directly or contingently liable for said obligations.
                                                                            7
14.      MISCELLANEOUS

         14.1 AGREEMENT TO COOPERATE. All the parties hereto agree to and will
         cooperate fully with each other in the performance of this Agreement
         and the Loan Documents, including without limitation executing and
         additional documents and instruments reasonable or necessary to the
         full performance of this Agreement. Without limiting the generality of
         the foregoing, Borrower agrees to execute such other and further
         documents and instruments as Bank may request to implement the
         provisions of this Agreement and to perfect and protect the liens and
         security interests created by this Agreement, the Security Agreements
         or the Guaranties or any other Loan Document.

         14.2 BENEFIT OF AGREEMENT. This Agreement shall be binding upon and
         inure to the benefit of and be enforceable by the parties hereto, their
         respective successors and assigns. No other person or entity


                                        8
<PAGE>   9
         shall be entitled to claim any right or benefit hereunder, including,
         without limitation, the status of a third party beneficiary hereunder.

         14.3 EFFECT OF AGREEMENT. Bank, Borrower and each Guarantor agree that
         except as expressly provided herein, the Loan Documents shall remain in
         full force and effect in accordance with their respective terms, and
         this Agreement shall not be construed to:

                  14.3.1 Impair the validity, perfection or priority of any lien
                  or security interest securing Borrower's obligations to Bank;

                  14.3.2 Waive or impair any rights, powers or remedies of Bank
                  under the Loan Documents;

                  14.3.3 Constitute an agreement by Bank or require Bank to
                  grant forbearance periods or extend the term of the Credit
                  Agreement or the time for payment of any of Borrower's
                  obligations to Bank except as expressly provided herein, none
                  of which Bank agrees or has agreed to do, and all of which
                  matters are in Bank's sole and absolute discretion; or

                  14.3.4 Make any other loans or other extension of credit to
                  Borrower or any Guarantor.

                  In the event of any inconsistency between the terms of this
                  Agreement and any other Loan Document, this Agreement shall
                  govern. Borrower and each Guarantor each acknowledges that it
                  has consulted with counsel and with such other experts and
                  advisors as it has deemed necessary in connection with the
                  negotiation, execution and delivery of this Agreement, or has
                  had an opportunity to so consult and has knowingly chosen not
                  to do so. This Agreement shall be construed without regard to
                  any presumption or rule requiring that it be construed against
                  the party causing this Agreement or any part hereof to be
                  drafted. The headings used in this Agreement are for
                  convenience only and shall be disregarded in interpreting the
                  substantive provisions of this Agreement.

         14.4 LIMITATION ON RELATIONSHIP. This Agreement and the other Loan
         Documents shall not be deemed or construed to create a partnership,
         tenancy in common, joint tenancy, joint venture, co-ownership or any
         other relationship aside from a continuing debtor-creditor relationship
         between Borrower and any Guarantor on the one hand and Bank on the
         other.

         14.5 INTEGRATION. This Agreement and the other Loan Documents are
         intended by the parties as the final expression of their agreement and
         therefore incorporate all negotiations of the parties hereto and are
         the entire Agreement of the parties hereto. Borrower and each Guarantor
         each acknowledges that it is relying on no written or oral agreement,
         representation, warranty, or understanding of any kind made by Bank or
         any employee or agent of Bank except for the agreements of Bank set
         forth herein or in the other Loan Documents. Except as expressly set
         forth in this Agreement, the other Loan Documents remain unchanged and
         in full force and effect.

         14.6 SEVERABILITY. In case any provision in this Agreement shall be
         invalid, illegal or unenforceable, such provision shall be severable
         from the remainder of this Agreement and the validity, legality and
         enforceability of the remaining provisions shall not in any way be
         affected or impaired thereby.

         14.7 REVERSAL OF PAYMENTS. If Bank receives any payments or proceeds of
         Collateral which are subsequently invalidated, declared to be
         fraudulent or preferential, set aside or required to be paid to a
         trustee, debtor-in-possession, receiver or any other party under any
         bankruptcy law, common law, equitable cause or otherwise, then, to such
         extent, the obligations or part thereof intended to be satisfied by


                                        9
<PAGE>   10
         such payments or proceeds shall be reserved and continue as if such
         payments or proceeds had not been received by Bank.

         14.8 MODIFICATION. This Agreement may not be amended, waived or
         modified in any manner without the prior written consent of the party
         against whom the amendment, waiver or modification is sought to be
         enforced.

         14.9 REIMBURSEMENT. Borrower shall reimburse Bank for all costs and
         expenses, including without limitation reasonable attorneys' fees and
         disbursements (and fees and disbursements of Bank's in-house counsel)
         expended or incurred by Bank in any arbitration, mediation, judicial
         reference, legal action or otherwise in connection with (a) the
         negotiation, preparation, amendment, interpretation and enforcement of
         the Loan Documents, including without limitation during any workout,
         attempted workout, and/or in connection with the rendering of legal
         advice as to Bank's rights, remedies and obligations under the Loan
         Documents, (b) collecting any sum which becomes due Bank under any Loan
         Document, (c) any proceeding for declaratory relief, any counterclaim
         to any proceeding, or any appeal, or (d) the protection, preservation
         or enforcement of any rights of Bank. For the purposes of this section,
         attorneys' fees shall include, without limitation, fees incurred in
         connection with the following: (1) contempt proceedings; (2) discovery;
         (3) any motion, proceeding or other activity of any kind in connection
         with a bankruptcy proceeding or case arising out of or relating to any
         petition under Title 11 of the United States Code, as the same shall be
         in effect from time to time, or any similar law; (4) garnishment, levy,
         and debtor and third party examinations; and (5) postjudgment motions
         and proceedings of any kind, including without limitation any activity
         taken to collect or enforce any judgment. All of such costs and
         expenses shall bear interest from the time of demand at the rate then
         in effect under the Notes.

         14.10 APPLICABLE LAW; JURISDICTION. Except as otherwise provided
         herein, this Agreement and all other Loan Documents and the rights and
         obligations of the parties hereto shall be governed by the laws of the
         State of California without regard to principles concerning choice of
         law. In any action arising out of or connected with this Agreement,
         Borrower and each Guarantor each hereby expressly consents to the
         personal jurisdiction of any state or federal court located in the
         State of California and also consents to service of process by any
         means authorized by federal or governing state law.

         14.11 COUNTERPARTS. This Agreement may be executed in any number of
         counterparts which, when taken together, shall constitute but one
         agreement.

         14.12 SURVIVAL. All representations, warranties, covenants, agreements,
         waivers and releases of Borrower and each Guarantor contained herein
         shall survive the payment in full of Borrower's obligations to Bank.

         14.13 NOTICES. Any notices required or contemplated under this
         Agreement shall be provided as specified in Section 9.1 of the Credit
         Agreement.

         14.14 TRANSFER BY BANK. Bank reserves the right to sell, assign,
         transfer, negotiate or grant participations in all or any part of
         Bank's rights and obligations under the Loan Documents. In that
         connection, Bank may disclose all documents and information which Bank
         may now or hereafter have relating to the Liabilities, Borrower or any
         Guarantor or the business of any of the foregoing.

IN WITNESS WHEREOF, Bank, Borrower and each Guarantor have executed this
Agreement as of the date SET forth in the preamble.

                        REPLACEMENT REVOLVING CREDIT NOTE

    $1,394,000.00                                                 March 31, 1996
    (Subject to Borrowing Base)

    Each signer of this Note ("Borrower") promises to pay to the order of The
    Bank of California, N.A. ("Bank") at its office at 400 California Street,
    San Francisco, CA 94014 or at such other place as Bank may designate in
    writing, in lawful money of the United States of America, the principal sum
    of ONE MILLION THREE HUNDRED NINETY FOUR THOUSAND DOLLARS ($1,394,000.00),
    or so much thereof as may be advanced and outstanding under the Borrowing
    Base, with interest on each Advance from the date it is disbursed until
    maturity, whether scheduled or accelerated, at a fluctuating rate per annum
    at all times equal to the rate Bank announces to be in effect from time to
    time as its prime rate (the "Prime Rate") plus 2.50%. The Prime Rate is a
    rate set by Bank based upon various factors including general economic and
    market conditions, and is used as a reference point for pricing certain
    loans. Bank may price its loans at, above, or below the Prime Rate.

    During the term of this Note, Borrower may borrow, repay and reborrow as
    Borrower may elect, in minimum amounts of ONE THOUSAND DOLLARS ($1,000.00)
    and subject to all limitations, terms and conditions contained herein and in

    Agreement"), provided however, that the outstanding principal balance of
    this Note shall at no time exceed the amount available under the Borrowing
    Base.

    Interest shall be payable on the first day of each consecutive month and

    and principal remaining unpaid shall be due and payable in full.

    Borrower hereby authorizes Bank to debit Borrower's account no. _________ at
    Bank's Sacramento office for the payment of interest hereunder. Borrower
    shall ensure that the balance of such account is adequate to fully pay all
    such interest when due.

    interest from their respective maturities, whether scheduled or accelerated,
    at a fluctuating rate per annum at all times equal to the Prime Rate plus
    5%, until paid in full, whether before or after judgment. Borrower shall pay
    such interest on demand.

    determine whether a specific request purportedly made by or on behalf of
    Borrower is actually authorized or authentic. As it is in Borrower's best
    interest that Bank advance funds in response to these forms of request,
    Borrower assumes all risks regarding the validity, authenticity and due
    authorization of any request purporting to be made by or on behalf of
    Borrower. Borrower promises to repay any sums, with interest, that are
    advanced by Bank pursuant to any request which Bank in good faith believes
    to be authorized, or when the proceeds of any Advance are deposited to the
    account of Borrower with Bank, regardless of whether any individual or
    entity ("Person") other than Borrower may have authority to draw against
    such account.

        remedies or the exercise of self help remedies shall not constitute a

of January 1996 are considered past due if not paid to BDTC by March 31, 1996.
For purposes of the calculation of the past due amount owed, the past due amount
shall be reduced by the amount owed for product to DII by BDTC.

DII will make timely payments to BDTC in accordance with the Extension and
Modification of the Exclusive Licensing Agreement. RDTC will defer principal
payments on the Promissory Note dated March 31, 1991 from October 1995 through
September 1996. Any principal payments made by DII to BDTC to date for the
months of October 1995 through January 1996 will be applied by BDTC against the
royalty/consulting receivable from DII and the Promissory Note
<PAGE>   2
balance will be adjusted accordingly. DII agrees the following expenditures will
not be made without prior written authorization/approval from BDTC while
principal payments are being deferred:

           - capital expenditures of any type;

           - research and development of any type;

           - debt of any type which does not exist on DII's balance sheet as of
           September 30, 1995: A fluctuation in accounts payable will not be
           considered an increase in debt;

           - compensation increases or benefit increases to any DII employees
           beyond planned annual cost of living adjustments (Exhibit B reflects
           all pay raises given since October 1, 1995);

           - no bonuses except those disclosed in Exhibit A.

9. DII agrees to prepare an operating budget to assist BDTC in projecting
anticipated cash flows.

10. Any and all sums paid or to be paid to JLM in excess of $120,000 per annum
by the purchaser, its assigns or successors shall be deemed to be an increase in
the sales price. The not present value of said excess shall be computed on a
monthly basis using a 10% discount factor for the period of time JLM receives
compensation in any form after the sale of DII from the purchaser, its assigns
or successors. The net present value shall be added to the sales price for
purposes of computing the amount to be paid to JLM under paragraph 12 of the
Letter of Intent. After Computing the amount due to JLM under paragraph 12, the
net present value of the amount in excess of $120,000 per annum shall reduce the
amount due JLM under paragraph 12. Compensation shall not include payments for
the benefit of JLM for health and dental insurance premiums or currently paid
automobile allowance. Increases in JLM's compensation package equal to the
compensation package received by the senior officer of BDTC (currently Curtis
Rocca) shall not be considered excess compensation. Unusual events that benefit
BDTC and therefore increase Curt Rocca's compensation, that are unrelated to DII
shall not be considered part of Curt Rocca's compensation package for purposes
Of this paragraph.

11. BDTC guarantees JLM, regardless of the sales price of DII, the sum of
$500,000 if the sale is agreed upon by June 30, 1996 and evidenced by an
executed sales agreement and the sale is finalized by September 30, 1996.
Otherwise the guarantee will be reduced by $100,000.

  12.        In addition to the minimum guarantee of paragraph 11, JLM will be 
paid:

             a.  Five percent of the sales price up to eleven million dollars.

             b. Twenty five percent of the sales price between eleven million
             dollars and twelve million dollars.


                                        2
<PAGE>   3
             c.  One half of the sales price above twelve million dollars.

The above amounts are not subject to right of claim, reduction or offset except
as provided in this agreement.

13. All patents developed by DII and JLM after April 1, 1991 shall be assigned
to JLM. To the extent the purchaser desires to utilize said patents, JLM
promises to grant the purchaser a royalty free license limited to dental
purposes only. JLM further agrees that all amounts paid by the purchaser for the
royalty free license shall be treated as part of the sales price of DII. Dental
purposes is defined as the maintenance and/or preservation of teeth; all
procedures involving the underlying bone structure and medical applications are
excluded from the definition of dental purposes. JLM reserves all other rights
in the patents.

14. BDTC DII and JLM acknowledge that each party may be required to make certain
representations and warranties to a prospective purchaser in connection with the
transaction contemplated by this Letter of Intent such as representations and
warranties as to the due authorization execution, delivery and enforceability of
a purchase agreement; good, valid and marketable title free of any adverse liens
relative to any assets or stock to be transferred by a party to a prospective

business affairs. BDTC agrees to provide all reasonable representations and
warranties required by a prospective purchaser relative to BDTC and DII and JLM
agree to provide all reasonable representations and warranties required by a
prospective purchaser with respect to DII and JLM. Each party shall be solely
responsible for all indemnity obligations relating to any breach of such party's
representations and warranties. At the closing of the transaction contemplated
by this Letter of Intent, BDTC, DII and JLM shall mutually release each other
from any and all claims, liabilities and other matters arising prior to the
closing.

15. Any controversy among the parties regarding the construction or application
of this letter of intent and any claim arising out of this letter of intent or
its breach, shall be submitted to arbitration upon the written request of one
party after the service of that request on the other parties.

BDTC shall appoint one person and DII and JLM shall jointly appoint one person
to hear arid determine the dispute. The cost of the arbitration shall be borne
by the losing party or in such proportions as the arbitrators shall decide.

16. This agreement shall terminate on October 1, 1996. Upon agreement of all
parties, it may be extended.

Dear Mr. Rocca and Mr. Mendoza:

This letter will set forth the general understanding of a transaction by which
Young Innovations Inc. or any of its affiliated or associated companies,
(collectively, "Young") intends to purchase certain agreed assets and
liabilities of Denticator International Inc. (hereinafter referred to as
Denticator). It is understood and agreed that Young has not conducted a due
diligence investigation of Denticator and that its proposal regarding the
acquisition of certain of the Denticator assets and liabilities and this letter
were prepared based upon certain limited information furnished to Young by
Denticator and Bio Dental Technologies Corp. (hereinafter referred to as Bio
Dental) which Young has assumed to be accurate and upon which it has relied.
Subject to the conditions in this letter and the execution of final definitive
agreements, an acquisition company affiliate of Young (hereinafter called New
Denticator) will purchase certain agreed assets and liabilities of Denticator
from Denticator in accordance with the following.

1. The assets and liabilities of Denticator at the date of closing of the
transaction contemplated hereby (the "Closing Date") will include those at March
31, 1996 (unaudited) as set forth in Schedule A of this letter, subject to
conditions set forth in paragraphs 2, 4, and 5 immediately below, and will
include all intangible assets of Denticator including patents, contract rights,
tradenames (including the name Denticator), copyrights, secrecy and noncompete
agreements, and all other property, assets and agreements necessary for Young to
continue the business of Denticator without interruption immediately following
the Closing Date.

2. At the Closing Date, Denticator will have retired the entire amount of
current and long-term bank indebtedness, which at March 31, 1996 totaled
($21,823 + $32,000) $53,823.

3. Denticator will surrender to Bio Dental the 50,000 Bio Dental options at the
Closing date and the options will be canceled by Bio Dental.

4. At the Closing Date, the royalty contract (dated March 31, 1991) and all
amendments and/or modifications of said contract, between Denticator and Bio
Dental, will be canceled and/or completed and Denticator will be free to
transfer the right to the Denticator name and right to manufacture and
distribute all of its products free from any future royalties and free from any
other liabilities from said contract. Denticator, Jose Mendoza (hereinafter
referred to as Mendoza) and Bio Dental agree that the "Letter of Intent"
executed on January 19, 1996, shall be superseded by the agreements related to
this purchase agreement and shall be terminated on the closing date.

5. At the Closing Date, Young will pay to Bio Dental, subject to the limitations
set forth below, cash in the amount of $7,549,087 (see Schedule B), such amount
referred to hereinafter as the "Cash Purchase Price". Young will also issue a
credit against future purchases (hereinafter referred to as the 'Product
Credit"). Said Product Credit shall be in the amount equal to, and payment in
full, for all accrued
<PAGE>   2
royalties to Bio Dental and notes current and long term to Bio Dental as
reflected on the audited balance sheet of Denticator at the Closing Date. It is
contemplated that this amount will be approximately $953,581 (see Schedule B),
plus any additions, less any payments, made and/or incurred in the normal course
of business (as reflected in the Denticator financials dated March 31, 1996)
between March 31, 1996 and the closing date. Said Product Credit shall be usable
by Bio Dental, or any of its affiliates, for the future purchase of products
from Young and any of its affiliates, including New Denticator, at prevailing
prices in effect at the time of the purchases. Denticator will make timely
payment to Bio Dental in accordance with the Extension and Modification of the
Exclusive License Agreement through the closing date. However, it is expressly
agreed that Denticator may deviate from said license agreement for purposes of
retiring its debt to the Bank of California, per paragraph two (2) above.

6. At the Closing Date, Young will purchase Denticator's agreed assets and
assume its agreed liabilities as reflected on its audited balance sheet on the
Closing Date. For payment of said assets Young will pay to Denticator $50,000
and assume said liabilities. It is understood that these agreed assets and
liabilities will be substantially the same as those reflected on Schedule A,
except that the Bank of California debt shall have been retired per paragraph
two (2) and paragraph five (5) above.

7. At the Closing Date, Mendoza will enter into an employment agreement, at his
same compensation that he presently receives from Denticator and a noncompete

with Mendoza, for the purchase of Young common stock, in the total amount of
$800,000 of said stock. Such stock option contract shall be exercisable by
Mendoza upon the meeting of certain financial performance goals of New
Denticator, as mutually agreed. As part of said stock option contract or stock
bonus plan, at the option of Mendoza, Young will repurchase for cash up to 40%
of the stock received by Mendoza under said stock option or bonus.

8. To assure the continuity of the management team, Young agrees, as part of
said employment agreement, per paragraph seven (7) above, to pay Mendoza an
amount equal to $305,000 in four equal three month installments, the first
payment being paid on the Closing Date.

liabilities by said New Denticator acquisition company, that said company will
be renamed Denticator International Co. and that Mendoza will be the president
and CEO, subject to the terms of the Mendoza employment contract. It is also the
intention of Young that said New Denticator will operate independently 'of Young
in its general business operations, however, there may be certain common and/or
joint practices such as banking, purchasing, accounting, planning and legal
functions.

10. In consideration for on going expenses of Young for incorporating the New
Denticator in its family of affiliates, New Denticator will pay annually to

CONFIDENTIAL

Mr. Curtis M. Rocca III
President
BioDental Technologies Corporation
11291 Sunrise Drive
Rancho Cordova, California 95742

        RE:     PROPOSED ACQUISITION OF BIODENTAL TECHNOLOGIES CORPORATION
                ("BDTC") BY ZILA, INC. ("ZILA") 

Dear Curt:

        This letter sets forth a proposal with respect to the principal terms
for the acquisition of all of the outstanding stock of BDTC by Zila (the
"Transaction"). If accepted by you, this letter will evidence the mutual
intention of BDTC and Zila to proceed diligently and in good faith to attempt
to negotiate the terms and conditions of a definitive written agreement
regarding the Transaction. Except for Sections 6 through 14 hereof, this letter
shall not constitute an agreement or binding obligation with respect to the
subject matter hereof, but shall only express the intent of the parties with
respect thereto. Any such agreement or binding obligation shall be evidenced
solely by a definitive agreement between BDTC and Zila (the "Agreement").

        Subject to the foregoing, we propose the following:

        1.      The Transaction.  Zila will acquire all of the outstanding stock
of BDTC (the "BDTC Stock"). Zila will issue 0.825 shares of Zila common stock
(the "Zila Stock") for each share of BDTC stock; provided that if the average
closing bid prices of the Zila Stock as reported by the NASDAQ Small Cap Market
during the ten trading days ending on the trading day that is five trading days
prior to the closing date (the "Calculation Period") is less than $6.00, Zila
<PAGE>   2
Mr. Curtis M. Rocca III
May 24, 1996
Page 2

shall pay for each share of BDTC Stock no less than $4.95 ($6.00 x 0.825) in
equivalent value of Zila Stock; provided further that if the average of the
closing bid prices of the Zila Stock as reported by the NASDAQ Small Cap Market
during the Calculation Period is greater than $7.75, Zila shall pay for each
share of BDTC Stock no more than $6.39 ($7.75 x 0.825) in equivalent value of
Zila Stock; provided however, that in no event will Zila issue less than 0.75
shares of Zila Stock for each share of BDTC Stock. On the closing date of the
Transaction there will be no more than 6,428,000 shares of BDTC Stock issued and
outstanding, plus any shares issued upon exercise of presently outstanding
options and warrants, and no more than 1,311,308 shares of BDTC Stock issuable
pursuant to options and warrants, less any shares issued upon exercise of
presently outstanding options and warrants. All shares of Zila Stock issued to
the holders of BDTC Stock will be registered with the Securities and Exchange
Commission ("SEC"), and at the closing date, such shares will not constitute
"restricted securities" under applicable federal and state securities laws. 

        2.      Board Representation.  On the closing date of the Transaction,
at least two persons nominated by BDTC will be appointed to serve on Zila's
Board of Directors.

        3.      Options.  As of the date of this letter, BDTC has outstanding
employee stock options to purchase 861,308 shares of BDTC Stock. In the
Transaction, provision will be made to exchange each such option to purchase a
share of BDTC Stock for an option to purchase one share of registered Zila
Stock on the same terms as such BDTC option so long as the holder of the Zila
option remains employed by Zila for one year following the closing date of the
Transaction. If the holder of the Zila option terminates his or her employment
with Zila within one year of the closing date of the Transaction, then each
such Zila option shall be exercisable in accordance with its terms for 0.825
shares of Zila Stock. As of the date of this letter, BDTC also has outstanding
warrants to purchase 450,000 shares of BDTC Stock. In the Transaction, provision
will be made to exchange each such warrant for a warrant to purchase that
number of shares of Zila Stock which the holder of such warrant would have
received in the Transaction if such holder had exercised the warrant and
acquire BDTC Stock prior to the Transaction.

        4.      Employment Arrangements/Employees.  On the closing date of the
Transaction, Zila will enter into employment arrangements with each of Curt
Rocca, Terry Bane and Tim Purdy on mutually acceptable terms and conditions.
All BDTC employees who are employed by Zila on the closing date of the
Transaction shall, for purposes of participating in Zila's employee stock
option plans, receive credit for each month of service to BDTC. Zila's
executive officers prior to the closing date of the Transaction will continue
in their respective positions after the closing date.

        5.      Payoff of BDTC's Debt.  BDTC has entered into a letter of
intent to sell its economic interest in royalties due from Denticator
International, Inc., which, if consummated, will produce sale proceeds which
will be sufficient and will be used to pay off all of BDTC's bank debt. If such
letter of intent is abandoned or does not result in such sale prior to the
closing of the Transaction, then, at the closing, Zila will pay off all of
BDTC's bank debt and subordinated debt, which shall not exceed $3.5 million in
the aggregate.

        6.      Agreement.  Commencing upon the execution hereof, and
continuing until the Termination Date (as hereinafter defined), the parties
will use their good faith efforts to attempt to negotiate the Agreement. The
Agreement shall contain provisions consistent with the intentions of the parties
set forth herein, together with customary covenants, conditions,
representations and warranties for a transaction of this type, and such other
terms and conditions as the parties shall determine to be mutually acceptable.
In the event that, for any reason, the Agreement is not executed prior to the
Termination Date, either party may terminate negotiations with respect to the
Transaction without liability to the other.

        7.      Term.  This letter and the agreements of the parties hereto
shall expire on July 1, 1996, or such later date as the parties may mutually
agree (the "Termination Date"). 

        8.      Due Diligence; Access to Books, Records and Personnel.  The
proposal set forth herein is subject to the satisfactory completion of your and
our respective due diligence investigations. During the term hereof, Zila and
its attorneys, accountants, consultants and representatives shall have access to
the books and records of BDTC and such other information pertaining to the
business and assets of BDTC as Zila shall reasonably request, and BDTC and its
attorneys, accountants, consultants and representatives shall have access to
the books and records of Zila and such other information pertaining to the
business and assets of Zila as BDTC shall reasonably request. Each of BDTC and
Zila shall provide the other with reasonable access to its officers and other
personnel for the purpose of conducting due diligence.

        9.      Conditions.  The proposal contained herein is subject to (i)
execution of mutually acceptable definitive agreements; (ii) receipt of required
approvals of Zila's and BDTC's respective stockholders; (iii) compliance with
all applicable securities laws and regulations; (iv) the ability of Zila to
account for the Transaction under the "pooling-of-interests" method of
accounting; and (v) if necessary, approval of the transaction by BDTC's lender.

        10.     Confidentiality.  During the course of negotiations and due
diligence, BDTC and Zila each from time to time may provide the other with
certain information regarding the business, operations and financial condition
of the other. Other than as described in subparagraph

(b) below, any information delivered by one party to the other in accordance
with this letter is referred to as the "Information." BDTC and Zila acknowledge
and agree that any Information provided to the other is proprietary and highly
confidential and that the unrestricted disclosure of any Information by one
party would result in substantial damage to the other, which damage would be
irreparable and extremely difficult to quantify. Accordingly, in consideration
of the furnishing of such information by BDTC and Zila to each other, BDTC and
Zila agree to maintain the confidentiality of any Information obtained from the
other, on the following terms and conditions:

        (a)  Each party hereto agrees that it will hold in strict confidence all
Information obtained from the other party in connection with or during the
course of any discussions or negotiations respecting the Transaction and will
use such Information only for the purposes of the discussions or negotiations
respecting the Transaction. Each party shall restrict access to the Information
to those officers, directors, employees, agents and representatives whose
duties require them to have access to the Information. Before disclosing any
Information to any such person, each party shall require such person to be
subject to the same restrictions and requirements respecting use, nondisclosure
and confidentiality as contained herein.

        (b)  It is understood and agreed that neither party has an obligation
to maintain confidential any information that:

                  (i)   Such party can establish to have been known to it at the
        time the information was disclosed;

                 (ii)   Such party can establish to have been or become known to
        the general public, other than as a result of a violation of this
        letter or any other agreement with the other party; or 

                (iii)   Such party can establish to have become known to it
        from any independent third party who had the right to disclose such
        information.

        (c)  Neither party nor any of its officers, directors, employees,
agents or representatives shall use any of the Information, directly or
indirectly, for competitive purposes or for any purpose other than in
connection with discussions and negotiations respecting the Transaction.

        (d)  Each party accepts full responsibility for any use or disclosure
of any Information by it or any of its officers, directors, employees, agents
or representatives in contravention of this letter.

        (d)  Neither party nor any of its officers, directors, employees,
agents or representatives may provide originals, copies or other reproductions
of any of the Information to any third party without the prior written consent
of the other party, except as required by law, legal process, rule, regulation
or regulatory authority. Any consent given by the other party may be
conditioned on the requirement that the party seeking consent obtain from the
third party a written agreement providing for the third party to be subject to
the same restrictions and requirements respecting use, nondisclosure and
confidentiality as contained in this letter.

        (f)  If either party or any of its officers, directors, employees,
agents or representatives is requested in any judicial or administrative
proceedings, or by any governmental or regulatory authority to disclose any
Information provided hereunder, that party will give the other written notice
of such request as promptly as practicable. If in the absence of a protective
order, that party or any of its officers, directors, employees, agents or
representatives are nonetheless compelled to disclose any Information, that
party may make such disclosure without liability hereunder provided that party
gives the other written notice of the Information to be disclosed as far in
advance of its disclosure as is practicable and uses its reasonable good faith
efforts to obtain reasonable assurance that confidential treatment will be
accorded to such Information.

        (g)  All Information will remain the property of the party providing
such Information. All documents provided by one party to the other or any one
or more of its officers, directors, employees, agents or representatives in
connection with any discussions or negotiations respecting the Transaction and
all copies or other reproductions of any and all of such documents, shall, at
the request of the party providing such documents, on or after the Termination
Date, be returned to such party, at the other party's cost and expense, and the
other party and its officers, directors, employees, agents or representatives
shall maintain strictly confidential all Information contained in the documents.

        (h)  Each party acknowledges and agrees that any violation of this
Section 9 would result in substantial and irreparable injury to the other
party, and that the other party would not have an adequate remedy at law with
respect to any such violation. Accordingly, each party agrees that, in the
event of any actual or threatened violation hereof, the other party shall have
the right and privilege to obtain, in addition to any other remedies that may
be available, equitable

relief, including temporary and permanent injunctive relief, to cease or
prevent any actual or threatened violation of any provision hereof.

        11.  Expenses.  Except as otherwise provided in the Agreement, each
party shall bear its own expenses incurred in connection with the proposed 
transaction.

       12.  Exclusivity.  During the term hereof, BDTC and Zila each agree that
they will not directly or indirectly solicit, entertain or encourage inquiries
or proposals to enter into an agreement, or negotiate with any third party, to
sell or enter into any merger or consolidation with respect to each of their
respective businesses and/or assets; provided, however, that (a) BDTC shall be
permitted to seek a buyer for its economic interest in royalties due from

        were outstanding at March 31, 1996 and 1995. Warrants to acquire 50,000
        shares of common stock at $4.00 per share were outstanding at March 31,

        at $3.11 per share were outstanding for part of the year ended March 31,
        1995. The effects of these warrants were antidilutive at March 31, 1996

        31, 1995 respectively. The effects of these options were antidilutive at
