ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

On December 20, 1999, Zila, Inc. (the "Company"), through its wholly owned
subsidiary, Integrated Dental Technologies, Inc. ("IDT"), completed the sale of
substantially all of IDT's assets and liabilities related to its PracticeWorks
division located in Gold River, California to InfoCure, Corporation
("InfoCure"), of Atlanta, Georgia for approximately $4.7 million. InfoCure is a
national provider of healthcare practice management software products and
services to targeted healthcare practice specialties and is listed on the NASDAQ
under the symbol INCX.

Under the terms of the agreement, the purchase price will be subject to
adjustment based on the net worth of the PracticeWorks division as of November
30, 1999, which will be determined over the next 60 days. In addition, ten
percent (10%) of the sales price will be held in escrow for one year in order to
secure the representations, warranties, and covenants made by the Company to
InfoCure. It is currently estimated that the adjusted sales price will be
approximately $4.6 million.

As previously disclosed in Form 10K/A for the fiscal year ended July 31, 1999,
on October 28, 1999, the Company's wholly owned subsidiary, Cygnus Imaging
("Cygnus"), completed the sale of substantially all of its assets and certain of
its liabilities to Procare Laboratories, Inc. ("Procare"), of Scottsdale,
Arizona for approximately $4.0 million. Procare is controlled by the former
owner and President of Cygnus, Egidio Cianciosi. The purchase price was paid
through the issuance to the Company of a note collateralized by the assets of
Procare. The note was paid in full on November 10, 1999. The sale resulted in a
$139,000 gain which was recognized in the Company's financial statements for the
period ended October 31, 1999.

Hundred Thousand and No/100 Dollars ($4,700,000.00).

Liabilities and the Base Consideration Amount, subject to adjustment pursuant to
Section 2.1.1. below.

                                       3
<PAGE>   5
                  2.1.1. Net Worth Adjustment. The Purchase Price will be
subject to adjustment as described in this Section 2.1.1. below.

                           A. Within sixty (60) days after the Effective Time,
Seller will deliver to Buyer a calculation of the net worth of the Acquired
Business as of November 30, 1999 (the "Effective Time Net Worth"). For purposes
hereof, Effect Time Net Worth shall be equal to (i) the total assets of the
Acquired Business as reflected on a balance sheet (the "November 30 Balance
Sheet") of the Acquired Business as of the Effective Time (prepared without
regard to any Excluded Assets) less (ii) the total liabilities of the Acquired
Business as reflected on the November 30 Balance Sheet (prepared without regard
to any Excluded Liabilities).

                           B. Buyer will have forty-five (45) days from receipt
of the November 30 Balance Sheet to object to the calculation of the Effective
Time Net Worth contained therein by delivering written notice to Seller. If
Seller does not receive notice of an objection within such time, the November 30
Balance Sheet prepared by Seller will be final and binding on the parties. If
Buyer timely notifies Seller of an objection, the parties will have thirty (30)
days from the date of Buyer's notice to resolve the objection. If the parties do
not resolve the objection within such time, either Seller or Buyer may submit
the dispute to Ernst & Young (the "Independent Auditors") for resolution, and
such resolution will be final and binding on the parties. The fees and expense
of the Independent Auditors will be borne by Seller and Buyer in proportion to
the respective differences between their positions submitted to the Independent
Auditors and the final determination of the Independent Auditors.

                           C. The November 30 Balance Sheet will be prepared on
a basis consistent with the preparation of that certain August 31, 1999 summary
balance sheet of the Acquired Business which has been previously provided to
Buyer.

                           D. The Purchase Price will be reduced if the
Effective Time Net Worth reflected on the November 30 Balance Sheet is less than
negative Three Hundred Thousand and No/100 Dollars ($300,000.00). The actual
amount of the reduction shall be the amount of such deficiency.

                           E. The Purchase Price will be increased if the
Effective Time Net Worth reflected on the November 30 Balance Sheet is greater
than negative Three Hundred Thousand and No/100 Dollars ($300,000.00). The
actual amount of the increase shall be the amount of such increase.

                           F. If there is an adjustment in the Purchase Price
pursuant to this Section 2.1.1., within ten (10) days after final determination
of the adjustment (whether by Buyer's failure to object, agreement of the
parties or determination by the Independent Auditors), Seller or Buyer, as
applicable, will pay the applicable amount by wire transfer of immediately
available funds to the account(s) designated by Seller or Buyer, as applicable.

                  2.1.2. Escrow Agreement. As security for the indemnities
provided herein by Seller, Seller shall deposit in escrow with the escrow agent
named in the Escrow Agreement attached hereto as EXHIBIT A the cash sum equal to
Four Hundred Seventy Thousand and No/100


                                       4
<PAGE>   6
Dollars ($470,000.00) (which shall be deducted from the Base Consideration
Amount referenced in Section 2.1.1. above).

         2.2. Assumed Liabilities. Buyer agrees to and shall at the Closing
assume and agree to pay, discharge and perform when lawfully due only those
liabilities, contracts, commitments and other obligations of Seller that are
listed on SCHEDULE 2.2 hereto (the "Assumed Liabilities").

         2.3. Excluded Liabilities. Except for the Assumed Liabilities set forth
in Section 2.2., Buyer shall not assume, and shall have no liability for, any
debts, liabilities, obligations, expenses, taxes, contracts or commitments of
the Seller or the Acquired Business of any kind, character or description,
whether accrued, absolute, contingent or otherwise, arising out of any act or
omission occurring or state of facts existing prior to or on the Closing Date
including, but not limited to, all liabilities of Seller for federal, state,
local or foreign taxes attributable to the operations of the Acquired Business
for any taxable year or portion thereof ending prior to the Closing Date,
arising out of the conduct of the Acquired Business prior to the Closing Date
(collectively the "Excluded Liabilities" and individually an "Excluded
Liability"). Seller shall remain fully liable for the Excluded Liabilities.

         2.4. Allocation of the Purchase Price. Within a reasonable time after
the November 30 Balance Sheet has been finally determined pursuant to Section
2.1.1., the parties shall execute the Allocation Agreement in the form of
EXHIBIT B (including appropriate adjustment to SCHEDULE 1 thereto).

sale of the Purchased Assets shall take place at Morris, Manning & Martin,
L.L.P., Atlanta, Georgia, on or about December 20, 1999, the second (2nd)

Sections 8. and 9. have been satisfied or complied with or, if not all

not been so satisfied or complied with have been waived by the party entitled to

Date."

         The parties agree to use their best efforts to cause all conditions to

Purchased Assets will be deemed to have transferred, and the Assumed Liabilities
will be deemed to have been assumed, as of the beginning of business on December

all representations, warranties and covenants shall extend to that date.

         3.2. Procedure at the Closing. At the Closing, the parties agree to
take the following steps in the order listed below (provided, however, that upon
their completion all such steps shall be deemed to have occurred
simultaneously):

                  3.2.5. Buyer shall deliver to Seller instruments, in the form

4.       REPRESENTATIONS AND WARRANTIES OF SELLER AND ZILA.

         In order to induce Buyer to enter into this Agreement and to consummate
the transactions contemplated hereunder, Seller and Zila, jointly and severally,
make the following representations and warranties as of the date hereof and as
of the Closing Date:

         4.1. Organization, Power and Authority of Seller. Seller is a
corporation duly organized and legally existing in good standing under the laws
of California and has full corporate power and authority to carry on the
Acquired Business as it is now being conducted, to own and lease the Purchased
Assets, to enter into this Agreement and to carry out the transactions and
agreements contemplated hereby. The Seller is in good standing and authorized to
do business in each jurisdiction in which the character of the Acquired Business
makes such qualification necessary except for such jurisdictions where the
failure to be in such standing and so authorized will not materially adversely
affect the financial condition, business or operations of the Seller or the
ability of the Seller to perform its obligations hereunder.

accounting principles which have been consistently applied through the
respective periods and present fairly the financial condition of the Acquired

the Purchased Assets.

                  4.5.2. Except as set forth on SCHEDULE 4.5.2 all taxes and

real estate leased, used or occupied by Seller in connection with its Acquired
Business (collectively, the "Real Property"). Except as set forth in SCHEDULE

the extent that such modifications are disclosed by the SCHEDULE 4.6.

                  Seller is not in default and no circumstances exist which
would result in a default, under any of such leases, and to the best knowledge
of Seller, no other party to such leases has the right to terminate, accelerate
performance under or otherwise modify (including upon the giving of notice or
the passage of time) any of such leases. To the best knowledge of Seller, no
lessor under any such lease is in default under any of such leases.

                  4.6.3. Seller has not assigned, transferred, conveyed,
mortgaged, deeded in trust, granted a security deed, subleased or encumbered any
interest in any of the leaseholds or subleaseholds described in SCHEDULE 4.6.

personal property set forth on SCHEDULE 2.2 and SCHEDULE 4.6), free and clear of
all Encumbrances, except for (i) Encumbrances for current taxes, assessments or
government changes or levies on property not yet due or delinquent or which are
being contested in good faith and for which adequate reserves have been

referred to as "Permitted Encumbrances") which are set forth in SCHEDULE 4.7.1.

                  4.7.2. The inventory and supplies of Seller consist of items
of a quality and quantity usable and saleable in the normal course of Seller's
Acquired Business at values in the aggregate at least equal to the values at
which such items are carried on its books. The values of obsolete or slow-moving
inventory and inventory of below standard quality, if any, have been written
down to the lower of cost or realizable market values or have been written off.

                  The value at which such inventories are carried on the Closing
Date Balance Sheet reflects the normal inventory valuation policies of Seller,
stating inventories at the lower of cost or market, all determined in accordance
with generally accepted accounting principles.

                  4.7.3. Except as otherwise set forth in this Agreement, the
tangible assets to be sold and transferred hereunder are to be sold and
transferred and are to be accepted by Buyer in an "AS IS" physical condition,

                           F. Except as set forth on SCHEDULE 4.9.2, with
respect to Seller Software which is licensed by Seller to third parties or used

Software or Intangibles listed on SCHEDULE 4.9.1 or 4.9.2, or their respective
past or current uses by or through Seller, has violated or infringed upon, or is

secrets and copyrights with respect to the Software. Seller has performed all
obligations imposed upon it with regard to the Customer Software and Other
Software which are required to be performed by it on or prior to the date
hereof, and neither Seller nor, to the knowledge of Seller, any other party, is
in breach of or default thereunder in any respect, nor to Seller's knowledge, is
there any event which with notice or lapse of time or both would constitute a
default thereunder.

                           I. To the knowledge of Seller, no person is violating
or infringing upon, or has violated or infringed upon at any time, any of

therein or right thereto, including, but not limited to, the right to royalty
payments. Except as listed on SCHEDULE 4.9.2, Seller has granted no third party
any exclusive rights related to any Owned Software.

                           K. No litigation is pending and no claim has been
made against Seller or, to the knowledge of Seller, is threatened, which
contests the right of Seller to sell or license to


                                       11
<PAGE>   13
any person or entity or use any of the Owned Software, or to the knowledge of
Seller, Customer Software or Other Software. No former employer of any employee
or consultant of Seller has made a claim against Seller or, to the knowledge of
Seller, against any other person, that Seller or such employee or consultant is
misappropriating or violating the Intangibles of such former employer.

                           L. Seller is not a party to or bound by and, upon the
consummation of the transactions contemplated by this Agreement, Buyer will not
be a party to or bound by (as a result of any acts or agreements of Seller), any
license or other agreement requiring the payment by Seller or its assigns of any
royalty or license payment, excluding such agreements relating to the Customer
Software to the extent such royalty or license payment is expressly set forth on

                           N. Except as set forth on SCHEDULE 4.9.2, the use,
adaptation, modification, reproduction, distribution, sale or exhibition of the
Software will not infringe upon or violate the privacy, publicity or moral
rights of any third party or defame any third party.

                           O. Except as set forth in SCHEDULE 4.9.2, there is no

               4.16.1. SCHEDULE 4.16 lists all employees and agents who on
the date hereof perform services on a regular basis in the Acquired Business
operations of or for Seller. No such employee or agent has terminated or given
notice of termination of his employment as of the date hereof, nor, to the
knowledge of Seller, plans to refuse employment with Buyer after the Closing
Date.

                           A. Prior to the Closing Date, Buyer may offer
employment to commence on the Closing Date to any or all of the employees of
Seller related to the Acquired Business as it may determine. Buyer shall have
full and absolute discretion in determining the terms, conditions and benefits
relating to such employment. Nothing in this Agreement shall obligate Buyer or
InfoCure to employ after the Closing Date any employee of Seller or to offer
employment to any employee of Seller on the same terms or conditions or with the
same benefits offered by Seller. Nothing in this Agreement shall create any
claim or right on the part of any employee of Seller and no such employee shall
be entitled to assert any claim or right hereunder. Seller agrees to reasonably
cooperate with buyer in connection with any notices required by law including,
without limitation, the Warren Act and its state law equivalent and regarding
any


                                       17

written communications made to the employees of Seller during the period from
the date hereof until the Closing Date which relate to the transactions
contemplated by this Agreement.

                           B. Seller and Buyer agree that the employees hired by
Buyer ("Employee) will be entitled to maintain health coverage through Seller's
existing group health plan(s) (not including any flexible spending arrangements
which constitute a group health plan, but including other medical and dental
coverages) through COBRA (as defined below) continuation coverage under such
plan through 12:01 a.m. on February 1, 2000 (the "COBRA Premium Payment End
Date"). To the extent that an Employee and his or her dependents is entitled to
a right to receive continuation coverage available pursuant to, and as required
under the provisions of, ERISA Sections 601 through 608 and Code Section
4980B ("COBRA") under the Seller's group health plan and/or the Seller's group
dental plan, if such Employee and his or her dependents exercises such right in
accordance with COBRA and the terms and provisions of such group health and/or
dental plan, the Buyer shall, solely during the period beginning with the
Closing Date and ending on the COBRA Premium Payment End Date, but not
thereafter, subsidize the COBRA premium required to be paid by such Employee
(and/or his or her dependents) for such continuation coverage by paying an
amount directly to the Employee (in a timely manner so that the Employee may
timely pay his required COBRA premium) such that when such amount is added to
the amount which would have been required to be paid by the Employee for the
coverage he or she had in place under Seller's group health plan immediately
prior to the Closing, the aggregate amount is equal to the COBRA premium
required to be paid by such Employee and his or her dependents (but, in no event
greater than the actual COBRA premium. The Employee and his or her dependents
shall remain completely responsible for timely paying any additional amount
required under COBRA, so that the total amount paid equals the COBRA premium.
This COBRA premium subsidy by the Buyer shall be provided from the Closing
through the COBRA Premium Payment End Date, but not thereafter, and is intended
to ensure that the Employees and their dependents have the ability to remain
covered under the Seller's group health and dental plans through 12:01 a.m.
February 1, 2000, by paying a monthly premium amount equal to the amount they
were paying prior to the Closing, and is not intended to alter the Seller's
group health plan(s) in any manner.

                           C. Seller shall remain liable for all "Seller
Employee Liabilities," regardless of when or how such liability arose, and
regardless of whether such liability may result in or has resulted in a claim
upon the Purchased Assets. For purposes of the preceding sentence, the term
"Seller Employee Liabilities" shall mean any claims, liabilities, costs,
expenses or compensation which exist, which arise by reason of, or which are in
any way connected with or based on (i) an employee's employment relationship
with Seller and/or the termination of such relationship; (ii) foreign, federal,
state, county or municipal fair employment practices act and/or any law,
ordinance or regulation promulgated by any foreign, federal, state, county,
municipality or other state subdivision as applied to employees of Seller; (iii)

retaliatory or wrongful discharge of any employee of Seller; (v) intentional or
negligent infliction of emotional distress or mental anguish upon employees of
Seller; (vi) outrageous conduct with respect to employees of Seller; (vii)

employment relationships involving employees of Seller and any third party;

Rights Act of 1964 and/or the Civil Rights Act of 1991 and/or 42 U.S.C. Section
1981 with respect to employees of Seller; (x) violations of the Age
Discrimination in Employment Act of 1967, the Age Discrimination Claims
Assistance Act of 1988 and/or the Older Workers' Benefit Protection Act with

reasonable prior notice, to Seller's premises sufficient to enable Buyer to
inspect the assets and properties of the Acquired Business, and Seller will
furnish to such representatives during such period all such information relating
to the foregoing investigation as Buyer may reasonably request; provided,
however, that any furnishing of such information to Buyer and any investigation
by Buyer shall not affect the right of Buyer to rely on the representations and
warranties made by Seller in or pursuant to this Agreement, and, provided
further that Buyer will hold in confidence all documents and information
concerning Seller so furnished.

         6.4. Preservation of and Access to Books and Records. Seller and Zila

longer period (i) as may be required by any federal, state, local or foreign
governmental body or agency; (ii) as may be reasonably necessary with respect to
the prosecution or defense of any audit, suit, action, litigation or
administrative arbitration or other proceeding or investigation that is then
pending or threatened or (iii) that is equivalent to the period established by
any applicable statute of limitations (or any extension or waiver thereof) with
respect to matters pertaining to taxes. Seller and Zila agree not to destroy any
books, records or other documents containing such information without the prior
written consent of Buyer.

         Seller and Zila shall afford to Buyer and its employees, counsel and

                                       28
<PAGE>   30
Purchased Assets and as may be appropriate otherwise to carry out the
transactions contemplated by this Agreement.

         10.2. Nonassignable Contracts. To the extent that the assignment
hereunder by Seller to Buyer of any contract, commitment, license, lease or
other agreement of Seller (the "Contracts") is prohibited or is not permitted
without the consent of any other party to the Contract, this Agreement shall not
be deemed to constitute an assignment of any such Contract if such consent is
not given or if such assignment otherwise would constitute a breach of, or cause
a loss of contractual benefits under, any such Contract, and Buyer shall assume
no obligations or liabilities thereunder.

         Prior to the Closing, Seller shall advise Buyer promptly in writing
with respect to any Contract as to which it knows it will not receive any
required consent. Without in any way limiting Seller's obligation pursuant to
Section 8.3. make efforts to obtain all consents and waivers necessary for the

reasonable arrangement designed to provide Buyer with the rights and benefits
(subject to the obligations) under the Contract, including, if reasonably
requested by Buyer, by enforcing for the benefit of Buyer any and all rights of
Seller against any other person arising out of breach or cancellation by such
other person, acting as an agent on behalf of Buyer, subcontracting to Buyer the
right to perform under the Contract on the same economic terms as applied to
Seller prior to the Closing and acting as Buyer shall otherwise reasonably
require, in each case at Buyer's expense.

         Acceptance of any such arrangement shall constitute a waiver by Buyer
of any claim or alleged breach under this Agreement with respect to such
Contracts.

         10.3. Announcements. Seller and Buyer shall work together after the
Closing to coordinate the preparation and mailing by each of any announcements
each of them desires to make to customers relating to this transaction.

interest) incurred in connection with this Agreement (including the acquisition

tax returns and other documentation with respect to such transfer, documentary,
sales, use, stamp, registration and other taxes and fees.

         10.5. Disclosure. Zila, Seller, Buyer and InfoCure each agree not to
issue any press release or make any public announcement or other disclosure to
competitors, customers, employees or any other person (except to employees and
agents on a need-to-know basis in order to complete the transactions
contemplated by this Agreement and who agree to maintain the confidentiality of
the disclosed information) concerning this Agreement except as required by


                                       29
<PAGE>   31
law or with the advance written approval of the other parties, which approval
will not be unreasonably withheld.

11.      INDEMNIFICATION.

         11.1. Agreement by Seller to Indemnify. Zila and Seller, jointly and
severally, agree to indemnify and hold harmless Buyer and InfoCure and each of
their respective officers, directors, shareholders, successors and assigns
(collectively, the "Seller Indemnified Parties") in respect of the aggregate of
all indemnifiable damages caused to the Acquired Business or any of the Seller
Indemnified Parties. The parties agree that the indemnification provisions set
forth in this Article 11. are the sole remedy for any claims of the Seller
Indemnified Parties relating to the Acquired Business or Purchased Assets and
this Agreement; provided, however, nothing in this Section 11. Shall preclude
Buyer or InfoCure from seeking damages that arise from fraud.

         For this purpose, "indemnifiable damages" caused to the Acquired
Business or any of the Seller Indemnified Parties means the aggregate of all
expenses, losses, penalties, costs, deficiencies, liabilities and damages
(including related counsel fees and expenses) incurred or suffered by the
Acquired Business or any of the Seller Indemnified Parties resulting from:

                  A. The breach of any warranty made by Seller in or pursuant to
this Agreement;

                  B. The breach of any of the covenants or agreements made by
Seller in this Agreement;

                  C. The failure of Seller to pay, discharge or perform any
liability or obligation of Seller which is not an Assumed Liability;

                  D. Any actions, claims, proceedings, demands, grievances or
disputes brought or initiated by third parties against the Acquired Business or
any of the Seller Indemnified Parties in connection with an Excluded Liability;

                  E. The conduct of the Acquired Business by Seller through and
including the Closing Date; or

                  F. Any actions, claims, proceedings, demands, grievances or
dispute brought or initiated by third parties against the Acquired Business or
any of the Seller Indemnified Parties in connection with any Plan (as defined in
Section 4.17.1.) or any Seller Employee Liabilities (as defined in Section
4.16.1.B.).

         The foregoing obligation of Zila and Seller to indemnify the Seller
Indemnified Parties shall be subject to each of the following principles or
qualifications:

                  11.1.1. Each of the representations and warranties made by
Zila and Seller in this Agreement or pursuant hereto, shall survive for a period
of two (2) years after the Closing Date, notwithstanding any investigation at
any time made by or on behalf of Buyer or InfoCure, and thereafter all such
representations and warranties shall be extinguished; provided, however, that


                                       30
<PAGE>   32
the representations and warranties made by Zila and Seller to the extent they
relate to Seller's title to the Purchased Assets shall survive forever; the
representations and warranties made by Seller to the extent they relate to any
Plan or Seller Employee Liabilities shall survive until no possible liability
with respect thereto can be asserted; and that the representations and
warranties made by Seller in Section 4.4. hereof ("Tax Matters") shall in each
case survive until the first (1st) anniversary of the later of:

                  A. The date on which applicable period of limitation on
assessment or refund of tax has expired; or

                  B. The date on which the applicable taxable year (or portion
thereof) has been closed.

         No claim for the recovery of indemnifiable damages may be asserted by
any of the Seller Indemnified Parties against Seller or its successors in
interest after such representations and warranties shall be thus extinguished;
provided, however, that claims first asserted in writing within the applicable
period shall not thereafter be barred. In addition, the Seller shall have no
liability with respect to indemnifiable damages until the total of all such
damages exceeds Seventy-Five Thousand and No/100 Dollars ($75,000.00) in which
event Buyer shall be entitled to claim only the excess of the amount of such
damages over Seventy-Five Thousand and No/100 Dollars ($75,000.00).
Notwithstanding the foregoing, in no event shall the aggregate liability of Zila
and Seller under this Section 11. exceed the Purchase Price.

         Notwithstanding any prior provision of this Agreement to the contrary,
to the extent that there exists, or there shall arise, any "Seller Controlled
Group Plan Liability", as that term is defined in Section 4.17.3. of this
Agreement, the Seller shall indemnify and hold harmless InfoCure, Buyer and
their subsidiaries, any successors or assigns thereto, and all employees,
officers, directors, agents, independent contractors and other persons
affiliated with InfoCure, Buyer and/or their subsidiaries or their successors
and assigns (herein the "Indemnitees") from and against any and all such
liabilities, and any losses, damages, claims, liabilities, actions, suits,
proceedings and costs and expenses of defense thereof, including reasonable
attorneys' fees, and the Seller shall take any action reasonably requested by
InfoCure to prevent the imposition of such liability. Notwithstanding any
provision of this Agreement to the contrary, to the extent that there exists, or
there shall arise, any Seller Employee Liabilities (as defined in Section
4.16.1.B.) as of and from and after the Closing Date, the Seller shall indemnify
and hold harmless the Indemnitees from and against any and all such liabilities,
and any losses, damages, claims, liabilities, actions, suits, proceedings and
costs and expenses of defense thereof, including reasonable attorneys' fees, and
the Seller shall take any action reasonably requested by InfoCure to prevent the
imposition of such liability. Notwithstanding any provision of this Agreement to
the contrary, the indemnification of the preceding two sentences shall survive
the Closing Date and shall remain in effect until no Seller Controlled Group
Plan Liability and no Seller Employee Liabilities could possibly be asserted
against any of the Indemnitees.

         11.2. Agreements by Buyer and InfoCure to Indemnify. Buyer and InfoCure
(the "Buyer Indemnifying Parties"), jointly and severally, agree to indemnify
and hold Seller and Zila and each of their respective officers, directors,
shareholders, successors and assigns (collectively,


                                       31
<PAGE>   33
for purposes of this Section 11.2., "Seller") harmless in respect of the
aggregate of all indemnifiable damages of Seller.

         For this purpose, "indemnifiable damages" of Seller means the aggregate
of all expenses, losses, costs, deficiencies, liabilities and damages (including
related counsel fees and expenses) incurred or suffered by Seller (in each case
net of any insurance or other third party recoveries) from:

                  A. The breach of any representation or warranty made by Buyer
pursuant to this Agreement; or

                  B. The breach of any of the covenants or agreements made by
Buyer or InfoCure in this Agreement.

                  C. Any actions, claims, proceedings, demands, grievances or
disputes brought or initiated by third parties against the Seller in connection
with the Assumed Liabilities, and in connection with Buyer's employment
practices and contractual obligations to third parties after the Closing Date.

         The foregoing obligation of Buyer Indemnifying Parties to indemnify
Seller shall be subject to each of the following principles or qualifications:

                  11.2.1. Each of the representations and warranties made by
Buyer in Section 5. of this Agreement shall survive for a period of two (2)
years after the Closing Date, and thereafter all such representations and
warranties shall be extinguished.

         No claim for the recovery of indemnifiable damages pursuant to clause
(i) of Section 11.2. may be asserted by Seller against Buyer Indemnifying
Parties or their successors in interest after such representations and
warranties shall be thus extinguished; provided, however, that claims first
asserted in writing within the applicable period shall not thereafter be barred.

         11.3. Matters Involving Third Parties. If any third party shall notify
Buyer or Seller (the "Indemnified Party") with respect to any matter which may
give rise to a claim for indemnification against any other Party (the
"Indemnifying Party") under this Section 11. then the Indemnified Party shall
notify each Indemnifying Party thereof promptly; provided, however, that no
delay on the part of the Indemnified Party in notifying any Indemnifying Party
shall relieve the Indemnifying Party from any liability or obligation hereunder
unless (and then solely to the extent that) the Indemnifying Party thereby is
damaged.

         If any Indemnifying Party notifies the Indemnified Party within fifteen
(15) days after the Indemnified Party has given notice of the matter that the
Indemnifying Party is assuming the defense thereof, then:

                  A. The Indemnifying Party will defend the Indemnified Party
against the matter with counsel of its choice satisfactory to the Indemnified
Party;

                                       32
<PAGE>   34
                  B. The Indemnified Party may retain separate co-counsel at its
sole cost and expense (except that the Indemnifying Party will be responsible
for the fees and expenses of the separate co-counsel to the extent the
Indemnified Party concludes that the counsel the Indemnifying Party has selected
has a conflict of interest);

                  C. The Indemnified Party will not consent to the entry of any
judgment or enter into any settlement with respect to the matter without the
written consent of the Indemnifying Party (not to be withheld or delayed
unreasonably); and

                  D. The Indemnifying Party will not consent to the entry of any
judgment with respect to the matter, or enter into any settlement which does not
include a provision whereby the plaintiff or claimant in the matter releases the
Indemnified Party from all liability with respect thereto, without the written
consent of the Indemnified Party (not to be withheld or delayed unreasonably).

         If no Indemnifying Party notifies the Indemnified Party within fifteen
(15) days after the Indemnified Party has given notice of the matter that the
Indemnifying Party is assuming the defense thereof, then the Indemnified Party
may defend against, or enter into any settlement with respect to, the matter in
any manner it may deem appropriate.

         11.4. Other Agreements. Any indemnity obligations which Zila and Seller
may have to Buyer can be discharged by the Escrow Agent from the funds held in
escrow pursuant to Section 2.1.2. above in accordance with the terms of the
Escrow Agreement.

12.      MISCELLANEOUS.

         12.1. Brokers' Commission. Buyer will indemnify and hold harmless
Seller from the commission, fee or claim of any person, firm or corporation
employed or retained or claiming to be employed or retained by Buyer to bring
about, or to represent it in, the transactions contemplated hereby. Seller will
indemnify and hold harmless Buyer from the commission, fee or claim of any
person, firm or corporation employed or retained or claiming to be employed or
retained by Seller to bring about, or to represent them in the transactions
contemplated hereby.

         12.2. Amendment and Modification. The parties hereto may amend, modify
and supplement this Agreement in such manner as may be agreed upon by them in
writing.

         12.3.    Termination.

                  12.3.1. Anything to the contrary herein notwithstanding, this
Agreement may be terminated and the transactions contemplated hereby may be
abandoned:

                           12.3.1.1. By the mutual written consent of all of the
Parties hereto at any time prior to the Closing Date;

                           12.3.1.2. Unless terminated pursuant to Section

         12.9. Schedules. To the extent any disclosure in a Schedule puts Buyer
on actual notice of the facts reflected therein, such disclosure shall be deemed
to be a disclosure in all other Schedules under this Agreement as to such facts.

         12.10. Governing Law/Consent to Jurisdiction. This Agreement shall be
governed by and construed in accordance with the laws of the State of Georgia
applicable to contracts made and to be performed herein. With respect to any
dispute, controversy or claim arising out of, relating to or in connection with,
this Agreement, or the breach, termination or validity hereof, the parties shall
first attempt to resolve the matter in good faith for a period of fourteen (14)
days, thereafter, any such dispute, controversy or claim shall be finally
settled by arbitration conducted in accordance with this Section. The
arbitration shall be conducted in accordance with the Commercial Arbitration
Rules of the American Arbitration Association (the "AAA") in effect at the time
of the arbitration, except as they may be modified herein or by mutual agreement
of the parties. The seat of the arbitration shall be Atlanta, Georgia and each
party hereto irrevocably submits to the jurisdiction of the arbitration panel in
Atlanta, Georgia. The arbitration shall be conducted by three (3) arbitrators,
at least two (2) of which are attorneys having more than seven (7) years
experience in the general mergers and acquisitions field. The party initiating
arbitration (the "Claimant") shall identify its arbitrator within twenty (20)
days of receipt of a request for arbitration (the "Request") and shall notify
the Claimant of such appointment in writing. If the Respondent fails to identify
an arbitrator within such twenty (20) day period, the arbitrator named in the
Request shall decide the controversy or claim as the sole arbitrator. Otherwise,
the two (2) arbitrators appointed by the parties shall appoint a third (3rd)
arbitrator within twenty (20) days after the Respondent has notified Claimant of
the appointment of the Respondent's arbitrator. When the third (3rd) arbitrator
has accepted the appointment, the two (2) party-appointed arbitrators shall
promptly notify the parties of the appointment. If the two (2) arbitrators
appointed by the parties fail or are unable to so appoint a third (3rd)
arbitrator, then the appointment of the third (3rd) arbitrator shall be made by
the AAA, which shall promptly notify the parties of the appointment. The third
(3rd) arbitrator shall act as chair of the panel. The arbitration award shall be
in writing and shall be final and binding on the parties. The award may include
an award of costs, including reasonable attorneys' fees and disbursements.
Judgment upon the award may be entered by any court having jurisdiction thereof
or having jurisdiction over the parties or their assets. Notwithstanding the
foregoing, the parties may apply to any court of competent jurisdiction for a
temporary restraining order, preliminary injunction, or other interim or
conservatory relief, as necessary, without breach of this Section and without
any abridgment of the powers of the arbitrators. The parties agree to be subject
to the jurisdiction of the Superior Court of Cobb County or United States
District Court for the Northern District of Georgia (provided said court has
subject matter jurisdiction), which shall be the exclusive venue and
jurisdiction for such adjudication, and the parties hereby agree to subject
themselves to the jurisdiction and venue of such court for all such purposes and
agree to waive any objections thereto.
