                              EMPLOYMENT AGREEMENT

         The Agreement made this 10th day of August 1999 between ALLIANCE
MEDICAL CORPORATION ("Employer") and TIM EINWECHTER ("Employee"). The parties
hereto, intending to be legally bound hereto, agree upon the following terms of
employment of Employee by Employer.

         1. TERM. Employment shall commence August 16th, 1999 and shall
terminate as provided in paragraph 5.

         2. DUTIES. Employee is employed in the capacity of CHIEF FINANCIAL
OFFICER and shall perform such duties for Employer and its affiliates as may be
requested of Employee by Employer.

         3. PERFORMANCE BY EMPLOYEE. Except as may be otherwise directed or
approved by Employer from time to time, during the period of employment under
this Agreement, Employee shall devote his full time and efforts to the business
and affairs of Employer and shall perform his duties competently and
efficiently. Employee agrees that during the period of his employment under this
Agreement he will not undertake any outside business affiliations without the
prior written approval of Employer.

         Employee may engage in such personal investment activities during the
term of this Agreement as Employee deems appropriate and consistent with
Employee's position hereunder so long as such activities do not materially
interfere with the performance of Employee's duties under this Agreement and are
not in contravention of this Agreement.

         4. COMPENSATION. For all services to be performed by Employee during
the term of employment under this Agreement (including, without limitation,
services as an officer, director, employee, member of any committee of Employer
or of any division or subsidiary of Employer, or otherwise), Employee shall:

                  (a) Receive an annual salary at the rate of One Hundred and
Thirty-Eight Thousand Dollars ($138,000) per year for the first year of such
term. Salary payments shall be made in accordance with Employer's customary
practice, but not less than bi-weekly. Employee's salary shall thereafter be
subject to annual review and adjustment by Employer, and/or by Employee's direct
supervisor;

                  (b) Be eligible to earn an annual bonus of an amount not to
exceed twenty-five percent (25%) of the then current annual salary, paid
quarterly in arrears. The annual bonus plan shall be reviewed with Employee at
the beginning of each fiscal year;

                  (c) In addition to any cash compensation payable hereunder, be
entitled to participate in the various fringe benefits generally made available
to employees of Employer;

                  (d) Car allowance at $500 per month;
<PAGE>   2
                  (e) Be entitled to three (3) weeks paid vacation during each
full year that this Agreement is in force. Such vacation shall not be
cumulative. The time or times during which vacation is taken shall first be
approved by Employer;

                  (f) Be reimbursed by Employer for any reasonable expenses
incurred in conjunction with his employment within thirty (30) days of
submitting same. Employee shall present to Employer an itemized written account
of expenses within thirty (30) days after they have been incurred. Employee
shall not be reimbursed for expenses in substantial amounts unless they have
been approved in advance by Employer;

         5. TERMINATION. This Agreement shall be terminated upon the happening
of any of the following events:

                  (a) Death. The Employee's death;

                  (b) Disability. In the event Employee becomes physically or
mentally disabled so as to become unable, for a period of more than Ninety (90)
consecutive calendar days or for more than Ninety (90) calendar days in the
aggregate during any twelve-month period, to perform his duties hereunder on a
full-time basis, Employer may at its option terminate Employee's employment
hereunder upon written notice;

                  (c) Cause. Employer may terminate Employee's employment
hereunder for Cause. "Cause" shall include but not be limited to:

                           (i) dishonesty in connection with the duties to be
performed by Employee;

                           (ii) continuing inattention to or neglect of the
duties to be performed by Employee, which inattention or neglect is not the
result of illness or accident;

                           (iii) willful disloyalty to Employer or any of its
affiliates; or

                           (iv) violation of any of the provisions of Paragraphs
6 and 7 hereunder.

                           (d) Without Cause. Employer, at its option, may
terminate Employee's employment hereunder for any reason and without cause upon
ninety (90) days written notice to Employee.

         6. DISCLOSURE OF INFORMATION. Employee shall not, during or any time
after termination of employment hereunder (whether or not for cause), without
authorization of Employer, disclose or make use of for himself or for any person
or corporation or other entity, any files or trade secrets or other confidential
information concerning the business, clients, methods, operations, financing or
services of Employer or its affiliates. Trade secrets and confidential
information shall mean information disclosed to Employee or known by him as a
consequence of his employment by Employer, whether or not pursuant to this
Agreement, and not generally known to or used by competitors in Employer's
business.
<PAGE>   3
         7. COVENANT NOT TO COMPETE.

                  (A) Restrictive Covenant. For a period of two (2) years after
termination of Employee's employment, whether or not for cause, Employee shall
not, within the Restricted Area as hereinafter defined, directly or indirectly
own, operate, control, be employed by, participate in, or be connected in any
way with the ownership, management, operation or control of any business which
is substantially similar to the business of Employer or any affiliate of
Employer to which Employee has provided services. FOR PURPOSES OF THIS SECTION,
THE "RESTRICTED AREA" MEANS THE UNITED STATES OF AMERICA.

                  (B) Solicitation of Customers or Employees. In furtherance of
the foregoing, and not in limitation thereof, for a period of two (2) years
after termination of employment (whether or not for cause), Employee shall not,
within the product market and within the Restricted Area set forth in
subparagraph (A) above, directly or indirectly solicit or service in any way, on
behalf of himself or on behalf of or in conjunction with others, any client or
customer, or prospective client or customer, which has been solicited or
serviced by Employer or any affiliate of Employer within one (1) year prior to
the termination of his employment.

                           So long as Employee is employed by Employer and for a
period of two (2) years after termination of employment, Employee shall not
solicit any employee of Employer or any of its affiliates to become employed by
or otherwise associated with Employee in any other business.

                  (C) Competitive Activities. Employee shall be deemed to be
competing with Employer or soliciting a customer, prospective customer or
employee of Employer if, without the knowledge and written consent of the Board
of Directors of Employer, Employee is engaged in any such activity directly or
indirectly, whether for his own account or as a principal, agent, proprietor,
officer, director, employee, consultant or in any other capacity for any other
person, corporation or other entity. The foregoing provision, however, shall not
prohibit Employee from investing in securities of any corporation whose
securities are listed on a national securities exchange or traded in the
over-the-counter market if Employee shall be the owner, beneficially or of
record, of less than five percent (5%) of any class of the stock of such
corporation.

                  (D) Extension of Period. If Employee violates this restrictive
covenant and Employer brings legal action for injunctive or other relief,
Employer shall not, as a result of the time involved in obtaining such relief,
be deprived of the benefit of the full period of the restrictive covenant.
Accordingly, the restrictive covenant shall be deemed to have the duration
specified in subparagraph (A) hereof, computed from the date such relief is
granted but reduced by the time expired between the date the period of
restriction began to run and the date of the first violation of the covenant by
Employee.

                  (E) Reformation or Judicial Modification. Employee
acknowledges and agrees that the duration and geographical restrictions set
forth herein have been specifically discussed and negotiated and are reasonable
in view of all the facts and circumstances known to Employee. Nevertheless, if
any court shall determine that such duration or geographical limits are
unenforceable, the restrictions set forth herein shall be deemed modified to
apply for the
<PAGE>   4
maximum duration and geographical area which are reasonable in view of all the
facts and circumstances, and the Agreement shall be reformed to that extent.

         8. REMEDIES OF EMPLOYER. As an employee of Employer, Employee may have
access to customer lists, trade secrets and other confidential information of
Employer. Moreover, his continued employment will be instrumental to the
continuity and development of Employer's business. Employee therefore
acknowledges that the restrictions contained in Paragraphs 6 and 7 of this
agreement are a reasonable and necessary protection of the legitimate interests
of Employer, that any violation of them could cause substantial injury to
Employer and that Employer would not have entered into this Agreement with
Employee without receiving the additional consideration of Employee's binding
himself to said restrictions. In the event of any violation of the said
restrictions, Employer shall be entitled, in addition to any other remedy, to
preliminary and permanent injunctive relief.

         9. SURRENDER OF BOOKS AND RECORDS. Employee acknowledges that all
files, lists, books, records, literature, products and any other materials owned
by Employer or its affiliates or used by them in connection with the conduct of
their business, shall at all times remain the property of Employer and its
affiliates and that upon termination of employment hereunder, irrespective of
the time, manner or cause of said termination, Employee will surrender to
Employer and its affiliates all such lists, books, records, literature, products
and other materials.

         10. SEVERABILITY. The invalidity or unenforceability of any particular
provision, or any part thereof, of this Agreement shall not affect the other
provisions hereof and this Agreement shall be continued in all respects as if
such invalid or unenforceable provision were omitted.

         11. NOTICES. All notices, requests, demands and other communications
required under this Agreement shall be in writing and shall be deemed duly given
and received (i) if personally delivered, on the date of delivery; (ii) if
mailed, three (3) days after deposit in the United States mail, registered or
certified, return receipt requested, postage prepaid and addressed as provided

      THIS LOAN AND SECURITY AGREEMENT dated June 11, 2001, between SILICON
VALLEY BANK, whose address is 3003 Tasman Drive, Santa Clara, California 95054
("Bank") and ALLIANCE MEDICAL CORPORATION, whose address is 10232 South 51st
Street, Phoenix, Arizona 85044 ("Alliance") and PARAGON HEALTH CARE CORPORATION,
whose address is 10809 Executive Center Drive, Suite 110, Little Rock, Arkansas
72211 ("Paragon") (Alliance and Paragon are sometimes collectively, jointly and
severally referred to herein as "Borrower"), provides the terms on which Bank
will lend to Borrower and Borrower will repay Bank. The parties agree as
follows:

1     ACCOUNTING AND OTHER TERMS

      Accounting terms not defined in this Agreement will be construed following
GAAP. Calculations and determinations must be made following GAAP. The term
"financial statements" includes the notes and schedules. The terms "including"
and "includes" always mean "including (or includes) without limitation," in this
or any Loan Document.

2     LOAN AND TERMS OF PAYMENT

2.1   PROMISE TO PAY.

      Borrower promises to pay Bank the unpaid principal amount of all Credit
Extensions and interest on the unpaid principal amount of the Credit Extensions.

2.1.1 REVOLVING ADVANCES.

      (a) Bank will make Advances not exceeding (i) the lesser of (A) the
Committed Revolving Line or (B) the Borrowing Base, minus (ii) the amount of all
outstanding Letters of Credit (including drawn but unreimbursed Letters of
Credit). Amounts borrowed under this Section may be repaid and reborrowed during
the term of this Agreement.

      (b) To obtain an Advance, Borrower must notify Bank by facsimile or
telephone by 12:00 p.m. Pacific time on the Business Day the Advance is to be
made. Borrower must promptly confirm the notification by delivering to Bank the
Payment/Advance Form attached as Exhibit B. Bank will credit Advances to
Borrower's deposit account. Bank may make Advances under this Agreement based on
instructions from a Responsible Officer or his or her designee or without
instructions if the Advances are necessary to meet Obligations which have become
due. Bank may rely on any telephone notice given by a person whom Bank believes
is a Responsible Officer or designee. Borrower will indemnify Bank for any loss
Bank suffers due to such reliance.

      (c) The Committed Revolving Line terminates on the Revolving Maturity
Date, when all Advances are immediately payable.

2.1.2 LETTERS OF CREDIT SUBLIMIT.

      Bank will issue or have issued Letters of Credit for Borrower's account
not exceeding (i) the lesser of the Committed Revolving Line or the Borrowing
Base minus (ii) the outstanding
<PAGE>   5
principal balance of the Advances; however, the face amount of outstanding
Letters of Credit (including drawn but unreimbursed Letters of Credit) may not
exceed $500,000. Each Letter of Credit will have an expiry date of no later than
180 days after the Revolving Maturity Date, but Borrower's reimbursement
obligation will be secured by cash on terms acceptable to Bank at any time after
the Revolving Maturity Date if the term of this Agreement is not extended by
Bank. Borrower agrees to execute any further documentation in connection with
the Letters of Credit as Bank may reasonably request.

2.1.3 ACQUISITION TERM LOAN.

      (a) Bank will make the Acquisition Term Loan to Borrower in a single
advance on the earlier of (i) Borrower's completion of its filing with the U.S.
Securities and Exchange Commission on Form S-1 or (ii) July 31, 2001.

      (b) Borrower will pay equal monthly installments of principal plus
interest (the "Acquisition Term Loan Payment"). Each Acquisition Term Loan
Payment is payable on the 11th of each month during the term of the Acquisition
Term Loan. Borrower's final Acquisition Term Loan Payment, due on April 30,
2004, includes all outstanding Acquisition Term Loan principal and accrued
interest.

2.1.4 EQUIPMENT TERM LOAN.

      (a) Bank will make an Equipment Term Loan available to Borrower. On the
Closing Date, Bank will make a single advance to Borrower in an amount not to
exceed 75% of the eligible Equipment previously financed under Borrower's
existing Equipment facility. Up to 15% of eligible Equipment may include
software and other soft costs, including sales tax, freight and installation
expenses. Borrower will deliver to Bank with the request for the Equipment Term
Loan an invoice for the Equipment to be refinanced.

      (b) Borrower will pay 36 equal installments of principal plus interest
(the "Equipment Term Loan Payment"). Each Equipment Term Loan Payment is payable
on the 11th of each month during the term of the Equipment Term Loan.

      (c) Borrower's final Equipment Term Loan Payment, due on April 30, 2004,
includes (i) all outstanding Equipment Term Loan principal and accrued interest,
plus (ii) an additional payment equal to 5% of the total amount advanced under
the Equipment Term Loan.

2.2   OVERADVANCES.

      If Borrower's Obligations under Section 2.1.1 and 2.1.2 exceed the lesser
of either (i) the Committed Revolving Line or (ii) the Borrowing Base, Borrower
must immediately pay Bank the excess.

2.3   INTEREST RATE, PAYMENTS.

(a) Interest Rate. (i) Advances accrue interest on the outstanding principal
balance at a per annum rate of 1 percentage points above the Prime Rate; (ii)
the Equipment Term Loan accrues interest at a per annum rate of 1.5 percentage

      Borrower and each Subsidiary is duly existing and in good standing in its
state of formation and qualified and licensed to do business in, and in good
standing in, any state in which the conduct of its business or its ownership of
property requires that it be qualified, except where the failure to do so could
not reasonably be expected to cause a Material Adverse Change.

      The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's formation documents, nor
constitute an event of default under any material agreement by which Borrower is
bound. Borrower is not in default under any agreement to which or by which it is
bound in which the default could reasonably be expected to cause a Material
Adverse Change.

5.2   COLLATERAL.

      Borrower has good title to the Collateral, free of Liens except Permitted
Liens. The Accounts are bona fide, existing obligations, and the service or
property has been performed or delivered to the account debtor or its agent for
immediate shipment to and unconditional acceptance by the account debtor.
Borrower has no notice of any actual or imminent Insolvency Proceeding of any
account debtor whose accounts are an Eligible Account in any Borrowing Base
Certificate. All Inventory is in all material respects of good and marketable
quality, free from material defects. Borrower is the sole owner of the
Intellectual Property, except for non-exclusive licenses granted to its
customers in the ordinary course of business. Each Patent is valid and
enforceable and no part of the Intellectual Property has been judged invalid or
unenforceable, in whole or in part, and no claim has been made that any part of
the Intellectual Property violates the rights of any third party, except to the
extent such claim could not reasonably be expected to cause a Material Adverse
Change.

consolidated financial condition since the date of the most recent financial
statements submitted to Bank.

5.5   SOLVENCY.

      The fair salable value of Borrower's assets (including goodwill minus

9     BANK'S RIGHTS AND REMEDIES

9.1   RIGHTS AND REMEDIES.

      When an Event of Default occurs and continues, Bank may, without notice or
demand, do any or all of the following:

      (a) Declare all Obligations immediately due and payable (but if an Event
of Default described in Section 8.5 occurs, all Obligations are immediately due
and payable without any action by Bank); (

      b) Stop advancing money or extending credit for Borrower's benefit under
this Agreement or under any other agreement between Borrower and Bank;

      (c) Settle or adjust disputes and claims directly with account debtors for
amounts, on terms and in any order that Bank considers advisable;

      (d) Make any payments and do any acts it considers necessary or reasonable
to protect its security interest in the Collateral. Borrower will assemble the
Collateral if Bank requires and make it available as Bank designates. Bank may
enter premises where the Collateral is located, take and maintain possession of
any part of the Collateral, and pay, purchase, contest, or compromise any Lien
which appears to be prior or superior to its security interest and pay all
expenses incurred. Borrower grants Bank a license to enter and occupy any of its
premises, without charge, to exercise any of Bank's rights or remedies;

      (e) Apply to the Obligations any (i) balances and deposits of Borrower it
holds, or (ii) any amount held by Bank owing to or for the credit or the account
of Borrower;

      (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for
sale, advertise for sale, and sell the Collateral. Bank is granted a
non-exclusive, royalty-free license or other right to use, without charge,
Borrower's labels, Patents, Copyrights, Mask Works, rights of use of any name,
trade secrets, trade names, Trademarks, servicemarks, and advertising matter, or
any similar property as it pertains to the Collateral, in completing production
of, advertising for sale, and selling any Collateral and, in connection with
Bank's exercise of its rights under this Section, Borrower's rights under all
licenses and all franchise agreements inure to Bank's benefit; and

      (g) Dispose of the Collateral according to the Code.

9.2   POWER OF ATTORNEY.

      Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrower's name
on any invoice or bill of lading for any Account or drafts against account
debtors; (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as the Code
permits. Bank may

                                       12
<PAGE>   16
exercise the power of attorney to sign Borrower's name on any documents
necessary to perfect or continue the perfection of any security interest
regardless of whether an Event of Default has occurred. Bank's appointment as
Borrower's attorney in fact, and all of Bank's rights and powers, coupled with
an interest, are irrevocable until all Obligations have been fully repaid and
performed and Bank's obligation to provide Credit Extensions terminates.

9.3   ACCOUNTS COLLECTION.

      When an Event of Default occurs and continues, Bank may notify any Person
owing Borrower money of Bank's security interest in the funds and verify the
amount of the Account. Borrower must collect all payments in trust for Bank and,
if requested by Bank, immediately deliver the payments to Bank in the form
received from the account debtor, with proper endorsements for deposit.

9.4   BANK EXPENSES.

      If Borrower fails to pay any amount or furnish any required proof of
payment to third persons, Bank may make all or part of the payment or obtain
insurance policies required in Section 6.5, and take any action under the
policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral. No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

9.5   BANK'S LIABILITY FOR COLLATERAL.

      If Bank complies with reasonable banking practices and the Code, it is
not liable for: (a) the safekeeping of the Collateral; (b) any loss or damage
to the Collateral; (c) any diminution in the value of the Collateral; or (d)
any act or default of any carrier, warehouseman, bailee, or other person.
Borrower bears all risk of loss, damage or destruction of the Collateral.

9.6   REMEDIES CUMULATIVE.

      Bank's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative. Bank has all rights and remedies provided
under the Code, by law, or in equity. Bank's exercise of one right or remedy is
not an election, and Bank's waiver of any Event of Default is not a continuing
waiver. Bank's delay is not a waiver, election, or acquiescence. No waiver is
effective unless signed by Bank and then is only effective for the specific
instance and purpose for which it was given.

9.7   DEMAND WAIVER.

      Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

11    CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

      Arizona law governs the Loan Documents without regard to principles of
conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of
the State and Federal courts in Maricopa County, Arizona.

      BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY CONTEMPLATED
TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS
WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT.
EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

12    GENERAL PROVISIONS

12.1  SUCCESSORS AND ASSIGNS.

      This Agreement binds and is for the benefit of the successors and
permitted assigns of each party. Borrower may not assign this Agreement or any
rights under it without Bank's prior written consent which may be granted or
withheld in Bank's discretion. Bank has the right, without the consent of or
notice to Borrower, to sell, transfer, negotiate, or grant participation in all
or any part of, or any interest in, Bank's obligations, rights and benefits
under this Agreement.

12.2  INDEMNIFICATION.

      Borrower will indemnify, defend and hold harmless Bank and its officers,
employees, and agents against: (a) all obligations, demands, claims, and
liabilities asserted by any other party in connection with the transactions
contemplated by the Loan Documents; and (b) all losses or Bank Expenses
incurred, or paid by Bank from, following, or consequential to transactions
between Bank and Borrower (including reasonable attorneys' fees and expenses),
except for losses caused by Bank's gross negligence or willful misconduct.

12.3  TIME OF ESSENCE.

      Time is of the essence for the performance of all obligations in this
Agreement.

12.4  SEVERABILITY OF PROVISION.

      Each provision of this Agreement is severable from every other
provision in determining the enforceability of any provision.

12.5  AMENDMENTS IN WRITING, INTEGRATION.

      All amendments to this Agreement must be in writing and signed by Borrower
and Bank. This Agreement represents the entire agreement about this subject
matter, and supersedes prior negotiations or agreements. All prior agreements,
understandings, representations, warranties, and negotiations between the
parties about the subject matter of this Agreement merge into this Agreement and
the Loan Documents.

12.6  COUNTERPARTS.

      This Agreement may be executed in any number of counterparts and by
different parties on separate counterparts, each of which, when executed and
delivered, are an original, and all taken together, constitute one Agreement.

12.7  SURVIVAL.

      All covenants, representations and warranties made in this Agreement
continue in full force while any Obligations remain outstanding. The obligations
of Borrower in Section 12.2 to indemnify Bank will survive until all statutes of
limitations for actions that may be brought against Bank have run.

12.8  CONFIDENTIALITY.

      In handling any confidential information, Bank will exercise the same
degree of care that it exercises for its own proprietary information, but
disclosure of information may be made (i) to Bank's Subsidiaries or Affiliates
in connection with their business with Borrower, (ii) to prospective transferees
or purchasers of any interest in the loans (provided, however, Bank shall use
commercially reasonable efforts in obtaining the agreement of such prospective
transferee or purchaser to the terms of this provision), (iii) as required by
law, regulation, subpoena, or other order, (iv) as required in connection with
Bank's examination or audit and (v) as Bank considers appropriate exercising
remedies under this Agreement. Confidential information does not include
information that either: (a) is in the public domain or in Bank's possession
when disclosed to Bank, or becomes part of the public domain after disclosure to
Bank; or (b) is disclosed to Bank by a third party, if Bank does not know that
the third party is prohibited from disclosing the information.

12.9  ATTORNEYS' FEES, COSTS AND EXPENSES.

      In any action or proceeding between Borrower and Bank arising out of the
Loan Documents, the prevailing party will be entitled to recover its reasonable
attorneys' fees and other reasonable costs and expenses incurred, in addition to
any other relief to which it may be entitled.

                             LITIGATION SCHEDULE

      On January 19, 2001, Vanguard Medical Concepts, Inc. filed a complaint
against Donny A. Green, one of our employees, and our company in the Ninth
Judicial Circuit in Orange County, Florida. The complaint alleges causes of
action for breach of contract and misappropriation of trade secrets arising from
the breach of a confidentiality and non-compete agreement between Mr. Green and
Vanguard and unauthorized access to confidential portions of Vanguard's web
site. Vanguard is seeking damages from us, including attorneys' fees and costs,
in excess of $10 million plus punitive damages. We deny that any trade secrets
were misappropriated and will vigorously defend this lawsuit.

      On March 15, 1999, Dr. Wade Hill filed a complaint against our company and
several of our subsidiaries in the Third Judicial District Court of Salt Lake
County, Utah. The complaint alleges conversion, fraud, breach of contract,
breach of fiduciary duty, unjust enrichment and conspiracy. The allegations
arise out of the March 1996 transaction in which Dr. Hill entered into a joint
venture with Pauline Sill and Raymond Graves. Dr. Hill alleges that Sill and
Graves misrepresented a business opportunity and defrauded him during the
formation of their joint venture, Applied Medical Technologies, L.L.C. Although
Sill and Graves appear to be the primary defendants, we were made a party to the
lawsuit when we acquired an indirect ownership interest in the joint venture.
Dr. Hill alleges that we furthered any fraud committed by Sill and Graves. Dr.
Hill seeks unspecified damages which could exceed $350,000. We deny ever having
committed any fraud and will vigorously defend this lawsuit.
