Item 2.           ACQUISITION OR DISPOSITION OF ASSETS

         Effective July 12, 1996, the Company completed the purchase of the
outstanding capital stock of MediTek Health Corporation ("MediTek") from HEICO
Corporation ("HEICO"), pursuant to a stock purchase agreement dated as of June
20, 1996 and effective as of July 1, 1996. The consideration was $13 million of
cash and a $10 million convertible note (the "Note"). The Note bears interest at
a rate of 6 1/2% per annum, is payable on June 30, 2001 and is convertible into
Common Stock of the Company ("USDL Common Stock") at $9.25 per share, or an
aggregate of 1,081,081 shares. The Company has agreed to register the USDL
Common Stock issuable upon conversion of the Note prior to January 1, 1997. The
USDL Common Stock is also subject to certain volume restrictions on resale until
June 30, 1998. In addition, HEICO granted to Jeffrey Goffman, the Company's
Chairman and Chief Executive Officer, a voting proxy with respect to the
election of directors and any vote involving a proposed change of control.

         MediTek owns and operates 16 diagnostic imaging centers located in New
Jersey, Florida, Georgia and Alabama, some of which are joint ventures with
hospitals. MediTek had net collected revenues in the fiscal year ended October
31, 1995 of $14.7 million, income before HEICO management fees and allocated
interest expense or $2,152,000 and net income before taxes of $581,000. The
Company expects that MediTek will have revenues of 1996 of over $20 million and
net income before taxes of over $3 million as a result of incurred revenues,
elimination of the management fee and some corporate overhead.

INDEPENDENT AUDITORS REPORT

To the Board of Directors and Stockholder of
MediTek Health Corporation


We have audited the accompanying consolodated balance sheets of MediTek Health
Corporation and subsidiaries (the "Company) as of April 30, 1996 and October
31, 1995, and the related consolidated statements of operations, changes in
HEICO Corporation investment, and cash flows for the year ended October 31,
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
assesing 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, such consolidated financial statements present fairly, in all
material respects, the financial position of the Company as of April 30, 1996
and October 31, 1995, and the results of its operations and its cash flows for
the year ended October 31, 1995 in conformity with generally accepted accounting
principles.

MEDITEK HEALTH CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial
Statements as of April 30, 1996 and for the year ended October 31, 1995

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF COMPANY
MediTek Health Corporation (the Company) is a wholly-owned subsidiary of HEICO
Corporation (HEICO or parent company). The Company is engaged in the
acquisition, development and operation of medical diagnostic imaging facilities
which specialize in magnetic resonance imaging (MRI), computed axial tomography
(CT), ultrasound, and other state-of-the-art diagnostic technologies. MediTek
offers its operation and management services to hospitals, physician groups and
other health care providers. As of April 30, 1996, MediTek operated a total of
twelve high technology medical diagnostic facilities (centers) in three States
(Florida, Georgia and New Jersey). In addition, MediTek has entered into
agreements to open its thirteenth center in Newark, New Jersey, to open its
fourteenth center in the Birmingham, Alabama area and to purchase a fifteenth
center in Fort Lauderdale, Florida (see Note 11).

USE OF ESTIMATES
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

BASES OF PRESENTATION
The accompanying consolidated financial statements include the operations,
assets and liabilities of the Company as a stand-alone entity. The financial
statements exclude HEICO's corporate assets and liabilities not specifically
identifiable to the Company, except for certain prepaid expenses and accrued
expenses which were allocated between the Company and HEICO based on consistent
and reasonable allocation methods.
         The consolidated financial statements include the accounts of the
Company and its wholly-owned or majority owned subsidiaries and controlled
partnerships. The Company's investments in uncontrolled entities are accounted
for under the equity method. All significant intercompany balances and
transactions are eliminated.
         Principally due to the use of estimates and allocations, the financial
information included herein may not necessarily reflect the financial position
and results of operations of the Company in the future or what the financial
position and results of operations of the Company would have been had it been a
separate, stand-alone entity during the periods presented. Management does not
consider it practicable to estimate what the results of operations would have
been had the Company operated as a separate, stand-alone entity.

<PAGE>
CASH AND CASH EQUIVALENTS
For purposes of the consolidated financial statements, the Company considers all
highly liquid investments purchased with an original maturity of three months or
less to be cash equivalents.

PROPERTY, PLANT AND EQUIPMENT
Property, plant and equipment is stated at cost. Depreciation and amortization
is provided mainly on the straight-line method over the estimated useful lives
of the various assets, including assets recorded under capital leases which are
amortized over the shorter of their useful lives or the term of the related
leases. Property, plant and equipment estimated useful lives are as follows:

         Buildings and components.............      30 years
         Building improvements................ 6 to 15 years
         Machinery and equipment.............. 3 to  8 years

         The costs of major renewals and betterments are capitalized. Repairs
and maintenance are charged to operations as incurred. Upon disposition, the
cost and related accumulated depreciation are removed from the accounts and any
related gain or loss is reflected in earnings.

INTANGIBLE ASSETS
Intangible assets include the excess of cost over the fair value of net assets
acquired and deferred charges which are amortized on the straight-line method
over their legal or estimated useful lives, whichever is shorter, as follows:

         Excess of cost, including con-
           tingent consideration as paid,
           over the fair market value
           of net assets acquired............. 29 to 40 years
         Deferred charges.....................  3 to  5 years

         The Company continually evaluates the periods of intangible asset
amortization to determine whether events and circumstances subsequent to the
origination dates of such assets warrant revised estimates of useful lives. In
addition, the Company periodically reviews the excess of cost over the fair
value of net assets acquired (goodwill) to assess recoverability based upon
expectations of undiscounted cash flows and operating income of each
consolidated entity having a material goodwill balance. An impairment would be
recognized in operating results, based upon the difference between each
consolidated entities' respective present value of future cash flows and the
carrying value of the goodwill, if a permanent diminution in value were to
occur. There have not been any significant revised estimates nor recognition of
goodwill impairment during the eighteen months ended April 30, 1996.

REVENUE RECOGNITION
Revenues are recognized on an accrual basis, primarily upon the rendering of
services. Patient revenues are reduced by contractual allowances for services
billed to third party reimbursement sources in addition to provisions for
doubtful accounts.


                                       -8-

INCOME TAXES
The Company has adopted Statement of Financial Accounting Standard (SFAS) No.
109 "Accounting for Income Taxes," which requires the use of the liability
method of accounting for deferred income taxes. The Company is a member of
HEICO's affiliated group and, therefore, is included in HEICO's consolidated
Federal income tax return. In accordance with the tax sharing agreement that
exists between the parties, the provision for income taxes is determined as
though the Company prepares its income tax return separately from HEICO and
includes Federal, state and local income taxes currently payable and those
deferred because of temporary differences between the financial statement and
tax basis of assets and liabilities.

HEICO CORPORATION INVESTMENT
HEICO's investment in the Company consists of HEICO's initial capital
contribution, the Company's accumulated deficit and the net payable to HEICO
resulting from cash and non-cash transfers and intercompany allocations.

FINANCIAL INSTRUMENTS
The carrying amounts of cash and cash equivalents, accounts receivable, accounts
payable and accrued expenses and other current liabilities approximate fair
value due to the relatively short maturity of the respective instruments. The
Company's financial instruments also include long-term debt. The estimated fair
values of such financial instruments have been determined by the Company using
available market information and interest rates as of April 30, 1996 and October
31, 1995. The fair value of these financial instruments were not materially
different than their carrying value.

IMPACT OF NEW ACCOUNTING STANDARD
In March 1995, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards No. 121 (SFAS 121) "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of."
SFAS 121 amends the impairment provisions of the existing accounting literature
which required the Company's long-lived assets to be carried at the lower of
cost or net realizable value. Under the new provisions, if the Company's
long-lived assets are determined to be impaired, the impairment loss is measured
based upon the difference between the fair value of the asset and its carrying
amount.
         SFAS 121 is required to be adopted in fiscal 1997. The Company has not
completed its analysis of the impact of this new pronouncement.

NOTE 2 - INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED PARTNERSHIPS

Condensed balance sheet and statement of operations information for the
Company's unconsolidated partnerships at April 30, 1996 and the year ended

                                                                    ------------

                                                                    -----------
  Income (loss)......................                               $  (458,000)
                                                                    ============

         The Company has recorded income for management services rendered to the
unconsolidated partnerships during fiscal 1995 in the amount of $526,000.
         The Company has an interest in one partnership through which it
operated two centers as a co-general partner. In November 1994, the Company
increased its ownership in the first of these two centers from 40.5% to 42% for
$136,000. In August 1995, the second of these two centers was merged with a
previously unrelated medical imaging business to form a new partnership. The
Company operates this center as a 50% co-general partner for which it
contributed $140,000. In October 1994, the Company acquired a portion of the
minority interests of the limited partners in a third partnership it operates as
the general partner for $88,000, increasing the Company's ownership from 37% to
49.5%. The Company accounted for these acquisitions using the purchase method.
The excess of the total acquisition cost of these purchases over the fair market
value of the assets acquired was not significant.
         In connection with the Company's general partnership interest in one of
its unconsolidated partnerships, the Company indemnified the seller of this
general partnership interest from liability relating to a guarantee and security
agreement for a $1.4 million mortgage on one of the partnership's centers.


                                      -10-

NOTE 3 - SALE OF ACCOUNTS RECEIVABLE

The Company has entered into an agreement with an unaffiliated third party
whereby it can sell certain accounts receivable with recourse. The aggregate
proceeds related to purchased receivables that remain uncollected can not exceed
$3,000,000 at any point in time. The proceeds from the sale of receivables
during fiscal 1995 totaled $8,626,000. As of April 30, 1996, the Company was
contingently liable for $2,239,000 related to $3,589,000 of sold accounts
receivable that remains uncollected. As of April 30, 1996, such sold accounts
receivable had $2,669,000 in reserve allowances, including $1,009,000 for
contractual allowances and $747,000 in hold back reserves, which management
believes is an adequate provision against any such uncollected accounts
receivables. The fees related to the sale of receivables have been included in
cost of services.

NOTE 4 - TRANSACTIONS WITH HEICO

HEICO provides certain corporate general and administrative services to the
Company including legal, treasury and finance for a fixed amount of $1,500,000
per year. Additionally, other costs related to specific services were allocated
to the Company on a basis that approximated either the proportional share of the
Company's usage of the actual services provided or a representative share of
certain corporate fixed expenses. Management believes these allocations are
reasonable. These historical amounts are not necessarily representative of the
costs that the Company would have incurred as a stand-alone entity.
         HEICO manages cash and financing requirements of all its business
segments. Generally, the Company's available cash is periodically forwarded to
HEICO and the Company's net cash requirements are subsequently transferred by
HEICO as necessary.
         The accompanying consolidated balance sheets reflect HEICO's total
investment in the Company, a portion of which represents HEICO's general
corporate financing. HEICO has only passed through to the Company interest
expense from a line of credit borrowing with a bank which proceeds were used
exclusively to finance a portion of the Company's acquisitions.
         Interest expense reflected in the consolidated statement of operations
does not necessarily reflect the interest expense the Company would have
incurred as a stand-alone entity.

         Advances and allocations for the year ended October 31, 1995 were as
follows:

Balance, October 31, 1994.........................           $14,023,000
Advances, net.....................................               637,000
Allocations:
   Allocated service costs........................               235,000
   Allocated interest expense.....................                71,000
   Income taxes...................................                23,000
   Management fee.................................             1,500,000
                                                             -----------
Balance, October 31, 1995.........................           $16,489,000
                                                             ===========

         The average monthly balance of advances and allocations during the year
ended October 31, 1995 was $15,810,000.
         Because HEICO manages the cash and financing requirements of the
Company as set forth above, it is not practicable to estimate cash paid on
behalf of the Company for interest and income taxes.
         The Company is one of the guarantors for a HEICO credit facility with a
bank, which had an outstanding balance of $475,000 as of April 30, 1996, and a
$2 million letter of credit of a HEICO subsidiary.

NOTE 5 - LONG-TERM DEBT AND CAPITAL LEASES

Long-term debt and capital leases consist of:

                                              ==========        ==========

         The amount of long-term debt maturing in each of the next five twelve
month periods ending April 30, is $336,000 in 1997, $336,000 in 1998, $371,000
in 1999, $393,000 in 2000 and $422,000 in 2001.

EQUIPMENT LOAN FACILITY

         In February 1996, the Company negotiated a restructuring of four
capital leases with an equipment provider whereby the total monthly payments
were reduced. This restructuring created a deferred gain of $1.4 million that is
being recognized as a reduction of expenses ratably over the remaining life of
these leases.
         The Company also leases certain property and equipment, including
medical and office facilities, diagnostic medical imaging equipment and office
equipment under operating leases. Some of these leases provide the Company with
the option after the initial lease term either to purchase the property at the
then fair market value or renew its lease at the then fair rental value.
Generally, management expects that leases will be renewed or replaced by other
leases in the normal course of business.
         Minimum payments for capital and operating leases having initial or
remaining noncancelable terms in excess of one year are as follows:

NOTE 10 - LITIGATION

The Company is involved in various legal actions arising in the normal course of
business. After taking into consideration legal counsel's evaluation of such
actions, management is of the opinion that the outcome of these matters will not
have a significant effect on the Company's consolidated financial statements.

NOTE 11 - OTHER COMMITMENTS

The Company has entered into agreements to open two new imaging centers in
Newark, New Jersey and Birmingham, Alabama. The centers are expected to begin
operation in August 1996. In connection with these centers, the Company has
entered into purchase commitments and equipment financing agreements aggregating
$2.7 million. In addition, the Company purchased a mobile MRI unit in May 1996
for approximately $650,000 for use at one of its centers. The purchase of mobile
MRI and deposits related to the purchase commitments have been funded by
advances from HEICO pending arrangement of permanent equipment financing.
         In May 1996, the Company, through a subsidiary, entered into an
agreement to purchase the stock of RNF II, Inc. (RNF) for $1,900,000 in cash and
a $600,000 8% note payable over three years. RNF operates a diagnostic imaging
center offering MRI services in Ft. Lauderdale, Florida. RNF had unaudited
annual revenues of approximately $2.5 million and unaudited annual pre-tax
income of approximately $700,000 in 1995. Consummation of the purchase agreement
is subject to the satisfactory completion of the Company's due diligence, which
must be completed by June 29, 1996. If the acquisition is consummated, it will
be accounted for as a purchase transaction for financial statement purposes.
         During fiscal years 1994 and 1993, the Company purchased the net assets
and businesses of two diagnostic imaging centers for consideration that included
notes payable which are contingent upon the level of future earnings of these
two centers. The final note payments are due June 30, 1996 and are estimated by
the Company to aggregate approximately $300,000. Contingent note payments, as
paid, are recorded as goodwill.

NOTE 12 - SUBSEQUENT EVENT

On June 20, 1996, HEICO entered into an agreement to sell the stock of
the Company to U.S. Diagnostic Labs, Inc.  The sale is subject to
customary closing conditions.

obligations set forth therein (which shall be completed on or prior to the

practices or on its ability to acquire any property or conduct its business in
any area. References in this Agreement to the phrase "to the best of
Stockholder's or MediTek's knowledge" or to the "knowledge of stockholder or
MediTek", or words of similar import, mean the actual (as opposed to imputed or

the case may be, and not to the knowledge of any other employee or agent of such
party.

         2.10. TITLE TO PROPERTIES; ENCUMBRANCES. MediTek has good, valid and
marketable title to all the properties and assets which it purports to own

free and clear of all liens, mortgages, security interests, pledges, charges and
encumbrances ("Encumbrances") (except as may be described in such Schedule 2.10

are valid and in full force and effect, and true copies thereof have been
heretofore made available to Purchaser. Except as set forth in such Schedule
2.11 or in any other schedule to this Agreement or disclosed in the Financial
Statements, neither MediTek or any Subsidiary:

         (a) has any agreements, contracts, commitments or restrictions which
are material to its business, operations or prospects or which require the

obligation of any person, corporation, partnership, joint venture, association,
organization or other entity.

                                       -6-

<PAGE>
and repairs which are material in nature or cost. Neither MediTek nor any
Subsidiary has received any notification that it is in violation of any
applicable building, zoning, anti-pollution, health or other law, ordinance or
regulation in respect of its Business or structures or their operations and to
the best of its knowledge, no such violation exists. There are no laws, statutes
or ordinances, or building or use restrictions applicable to the building,
structures and appurtenances owned or leased by MediTek or any Subsidiary which
might prohibit or impair the uses presently being made thereof in any material
respect.

         2.13. LEASES. Schedule 2.13 contains an accurate and complete list of
the terms of all leases pursuant to which MediTek or any Subsidiary leases real
or personal property, other than leases of office equipment (including, without
limitation, furniture, computer equipment, telephone systems, photocopiers and
postage meters) and leases which provide for annual rentals of less than
$10,000. All such leases are valid, binding and enforceable in accordance with
their terms, and are in full force and effect; there are no existing defaults by
MediTek or any Subsidiary thereunder.

         2.14. TAXES. Stockholder has duly filed all tax reports and returns
required to be filed by it relating to MediTek (the "Tax Returns") and has duly
paid all taxes and other charges due or claimed to be due from it relating to
MediTek by federal, state or local taxing authorities (including, without
limitation, those due in respect of the properties, income, franchises,
licenses, sales or payrolls of any of them); the reserves for taxes reflected in
the Financial Statements are adequate; and there are no tax liens upon any
property or assets of MediTek except liens for current taxes not yet due. No
state of facts exists or has existed which would constitute ground for the
assessment of any tax liability against MediTek by the Internal Revenue Service.
All taxes that MediTek or any Subsidiary is or was required by law to withhold
or collect have been duly withheld or collected and, to the extent required,
have been paid to the proper governmental body or other person. To the best of
stockholder's and MediTek's knowledge, there is no claim, audit, action, suit,
proceeding or investigation with respect to taxes due or claimed to be due from
MediTek or any Tax Return filed or required to be filed by or relating to
MediTek pending or to the best of Stockholder's and MediTek's knowledge,
threatened against or with respect to MediTek.

         2.15. INSURANCE. Schedule 2.15 contains an accurate and complete list
of all material policies of fire, liability (including malpractice), workmen's
compensation and other forms of insurance owned or held by MediTek or any
Subsidiary. All such policies are in full force and effect, all premiums with
respect thereto covering all periods up to and including the Closing Date have
been paid, and no notice of cancellation or termination has been received with
respect to any such policy. To the best of Stockholder's and MediTek's
knowledge, such policies are sufficient for compliance with all requirements of
law and all agreements to which MediTek or any Subsidiary is a party; are valid,
outstanding and enforceable policies. Except as set forth in Schedule 2.15, such
policies will remain in full force and effect through the respective dates set
forth in Schedule 2.15 without the payment of additional premiums; and will not
in any way be affected by or terminate or lapse by reason of, the transactions
contemplated by this Agreement. Schedule 2.15 identifies all risks which MediTek
or any Subsidiary has designated as being self-insured. Neither MediTek nor any
Subsidiary has been refused any insurance with respect to its assets or
operations, nor has its coverage been limited, by any insurance carrier to which
it has applied for any such insurance or with which it has carried insurance
during the last two years.

         3.03. NO VIOLATION. Neither the execution and delivery of this
Agreement or the other Acquisition Documents nor the consummation of the
transactions contemplated hereby or thereby will violate any provisions of the
Certificate of Incorporation or By-Laws of Purchaser, or violate, or be in
conflict with, or constitute a default (or any event which, with notice or lapse
of time or both, would constitute a default) under, or cause the acceleration of
the maturity of any debt or obligation pursuant to any agreement or commitment
to which Purchaser is a party or by which Purchaser is bound, or violate any
statute or law or any judgment, decree, order, regulation or rule of any court
or governmental authority.

Annual Report on Form 10-KSB for the year ended December 31, 1995 and its
Quarterly Report on Form 10-QSB for the three months ended March 31, 1996 (the

make the statements therein, in light of the circumstances under which they were
made, not misleading. The financial statements in such Reports, together with
the notes thereto, present fairly the consolidated financial position of
Purchaser and its subsidiaries as of the respective dates indicated and the
consolidated results of operations, consolidated changes in stockholders' equity

debt by Purchaser or any subsidiary or any material adverse change in its
condition (financial or other), net worth, results of operations, business or
properties.

         3.06 LICENSES AND PERMITS. Purchaser and its subsidiaries have
sufficient licenses, permits and other governmental authorizations as are
required for the conduct of their businesses or the ownership of their
properties and are in all material respects complying therewith except where the
failure to obtain or comply with such permits would not have a material
adversely affect the financial condition, results of operations, business or
properties of Purchaser and its subsidiaries taken as a whole.

         3.07. LITIGATION. There is no pending or threatened action, suit,
inquiry, proceeding or investigation by or before any court or governmental or
other regulatory or administrative agency or commission pending or threatened
against or involving Purchaser or its subsidiaries, or which questions or
challenges the validity of this Agreement or any action taken or to be taken by
Purchaser or its subsidiaries pursuant to this Agreement or in connection with
the transactions contemplated hereby; nor is there any valid basis for any such
action, proceeding or investigation.

         3.08. BROKERS AND FINDERS. Neither Purchaser nor any of its officers,
directors or employees has employed any broker or finder or incurred any
liability for any brokerage fees, commissions or finders' fees in connection

limitation, the Reports), certificate, or other writing furnished or to be
furnished by Purchaser to Stockholder or any of its representatives pursuant to
the provisions hereof or in connection with the transactions contemplated
hereby, contains or will contain any untrue statement of material fact or omits
or will omit to state any material fact necessary, in light of the circumstances
under which it was made, in order to make the statements herein or therein not
misleading.

                                   ARTICLE IV

                                    COVENANTS

         4.01 MediTek and Stockholder hereby covenant and agree with Purchaser:

         (a) CONSENTS. MediTek will obtain, prior to the Closing, all consents
necessary to the consummation of the transactions contemplated hereby,
including, without limitation, (i) if required, the consent of each person
holding a mortgage or lien on real property or personal property, owned or
leased by MediTek, to the Acquisition; and (ii) use its best efforts to assist
Purchaser in obtaining all necessary approvals from any governmental agencies or
departments as may be necessary or desirable in connection with the Acquisition.
All such consents will be in writing and executed counterparts thereof will be
delivered to Purchaser prior to the Closing.

                                      -11-

<PAGE>
         (b) SUPPLEMENTS TO SCHEDULES. From time to time prior to the Closing,
Stockholder and MediTek will promptly supplement or amend any Schedule hereto
with respect to any matter hereafter arising which, if existing or occurring at
the date of this Agreement, would have been required to be set forth or
described in any such Schedule. No supplement or amendment of any such Schedule
made pursuant to this Section shall be deemed to cure any breach of any
representation or warranty made in this Agreement unless Purchaser specifically
agrees thereto in writing. If Purchaser expressly agrees in writing to any
supplement or amendment to any such Schedule, the existence of any such express
amendment or supplement will not be a basis for the Purchaser's refusing to
close the transaction contemplated by this Agreement or a basis for Purchaser's
claim for, or entitlement to, damages occasioned by such breach or
misrepresentation or for indemnification under Article X hereof in respect
thereof. If Purchaser does not agree in writing to any such supplement or
amendment, its sole recourse and remedy for such breach of warranty or
misrepresentation shall be to be relieved of its obligation to close the
transactions contemplated hereunder. If, in spite of being relieved of its
obligations to close, Purchaser nevertheless proceeds with the closing
hereunder, Purchaser shall be deemed to have waived any right or claim for
damages or indemnification by reason of (i) such breach of misrepresentation or
(ii) any fact or circumstance which is disclosed to Purchaser in any such
supplement or amendment (notwithstanding Purchaser's unwillingness to agree
thereto) prior to the Closing hereunder.

         (c) OTHER TRANSACTIONS. Except as hereinafter provided, neither MediTek
nor Stockholder shall enter into any discussions concerning, or approve or
recommend any merger, consolidation, disposition of all or substantially all of
the business, properties or assets (other than pursuant to this Agreement),
acquisition or other business combination, or proposal therefor, or furnish or
cause to be furnished any information concerning the business, properties or
assets of MediTek to any party in connection with any MediTek transaction
involving the acquisition of MediTek or all or any substantial part of its
assets by any person other than Purchaser. If Stockholder or MediTek receives
any offer or proposal, written or otherwise, of the type referred to in the
immediately preceding sentence (a "Competing Transaction"), Stockholder shall
promptly inform Purchaser of such offer or proposal and furnish Purchaser with a
copy thereof if such offer or proposal is in writing. Nothing contained in this
section, however, shall prohibit the Board of Directors of Stockholder from
furnishing information to, or entering into discussions or negotiations with,
any person or entity in connection with an unsolicited bona fide proposal by
such person or entity to enter into a Competing Transaction if, and only to the
extent that (A) the Board of Directors of Stockholder after consultation with
and based upon the advice of independent legal counsel (which may include its
regularly engaged independent legal counsel), determines in good faith that such
action is required for the Board of Directors of Stockholder to comply with its
fiduciary duties to stockholders and (B) prior to furnishing such information
to, or entering into discussions or negotiations with, such person or entity,
Stockholder (x) provides written notice to Purchaser to the effect that it is
furnishing information to, or entering into discussions or negotiations with,
such person or entity and (y) receives from such person or entity an executed
confidentiality agreement in reasonably customary form. Notwithstanding the
foregoing, Stockholder and MediTek shall give Purchaser the right to match the
terms of any Competing Transaction prior to entering into a binding agreement
with respect thereto.

                                      -12-

<PAGE>
         (d) FULL ACCESS. Stockholder and MediTek have heretofore afforded to
Purchaser, its counsel, accountants and other representatives full access to the
facilities, properties, books and records of MediTek to enable Purchaser to make
such investigations as it shall desire to make of the affairs of MediTek and
Purchaser has substantially completed such investigations. MediTek will cause
its officers and accountants to furnish to Purchaser the audited and unaudited
Financial Statements of April 30, 1996, together with such additional financial
and operating data and other information as Purchaser shall from time to time
reasonably request.

         (d) REMEDIES. Subject to the limitations contained in Section 4.01(b),
in the event of the breach or threatened breach by MediTek or Stockholder of any
of the terms and conditions of this Agreement, then Purchaser shall be entitled,
if it so elects, to institute and prosecute any proceedings in any court of
competent jurisdiction either at law or in equity, for such relief as it deems
appropriate including, without limiting the generality of the foregoing
proceedings, to obtain damages for any breach of this Agreement or to enforce
the specific performance thereof by MediTek or Stockholder. If, in any such
action, Purchaser is successful in whole or in part, Stockholder shall further,
as an element of Purchaser's damages, be liable for the attorney's fees of
Purchaser in the prosecution of such action or proceeding.

         4.02     Purchaser hereby covenants and agrees with Stockholder that

         (a) TAX RETURNS. Purchaser will cooperate with Stockholder with respect
to the filing and auditing of tax returns with respect to MediTek for all
periods prior to the Closing Date, will keep copies of all tax returns filed
with respect to MediTek for a period of eight years from the Closing and shall
give Stockholder such access to such returns as Stockholder reasonably requires
with respect to preparation of its tax returns.

         (b) REMEDIES. In the event of the breach or threatened breach by
Purchaser of any of the terms and conditions of this Agreement, then Stockholder
shall be entitled, if it so elects, to institute and prosecute any proceedings
in any court of competent jurisdiction either at law or in equity, for such
relief as it deems appropriate including, without limiting the generality of the
foregoing proceedings, to obtain damages for any breach of this Agreement or to
enforce the specific performance thereof by Purchaser. If, in any such action,
Stockholder is successful in whole or in part, Purchaser shall further, as an
element of Stockholder's damages, be liable for the attorney's fees of
Stockholder in the prosecution of such action or proceeding.

                                    ARTICLE V

                                    ARTICLE X

                                 INDEMNIFICATION

         10.01. INDEMNIFICATION BY STOCKHOLDER. (a) In the event that the
transactions contemplated by this Agreement are consummated, Stockholder shall
indemnify Purchaser and hold Purchaser harmless from, against and in respect of
and shall on demand reimburse Purchaser for: (i) all its losses, liabilities,
damages, costs and expenses arising from any misrepresentation or breach of any
representation, warranty, covenant or agreement on the part of Stockholder or
MediTek under this Agreement; (ii) any and all actions, suits, claims, or legal,
administrative, arbitration, governmental or other proceedings or investigations
against Purchaser that relate to MediTek or the Business in which the principal
event giving rise thereto occurred before the Closing Date or which result from
or arise out of any action or inaction before the Closing Date of Stockholder,
MediTek or any employee, agent, representative or subcontractor of MediTek in
each case, where such event or action or inaction is not disclosed in this
Agreement, any schedule hereto or the Financial Statements; and (iii) any and
all actions, suits, proceedings, demands, assessments, judgments, costs and
expenses, including without limitation, reasonable legal fees and expenses,
incident to any of the foregoing or incurred in investigating or attempting to
avoid same or to oppose the imposition thereof, or in enforcing this indemnity
(collectively, "Losses"). Notwithstanding the foregoing in the event that a
court of competent jurisdiction having final adjudicative authority and from
which no appeal is available shall determine that Purchaser is not entitled to
indemnification then Purchaser shall not be entitled to recover its legal fees,
costs or expenses with respect to such claim from the Stockholder.

         (b) Stockholder shall not be required to indemnify the Purchaser under
Section 10.01(a) unless the amount of any Loss for which the Purchaser seeks
indemnification under Section 10.01(a), when aggregated with all other such
Losses, exceeds $250,000 after the adjustment in the final sentence of this
paragraph. Stockholder's maximum liability hereunder shall not exceed $3,000,000
in the aggregate. For purposes of the calculation under this Section 10.01(b),
there shall be an offset against Losses of an amount equal to the sum of (i) the
value of any net tax benefit actually realized by Purchaser (by reason of a tax
deduction, basis reduction, credits or otherwise) and (ii) the amount of any
cash payment actually received by Purchaser or MediTek after the Closing Date
covering any such any Loss from any insurance policy.

         10.02. INDEMNIFICATION BY PURCHASER. In the event that the transactions
contemplated by this Agreement are consummated, the Purchaser shall indemnify
Stockholder and hold it harmless from,

                                      -22-

<PAGE>
against and in respect of and shall on demand reimburse Stockholder for: (i) all
its losses, liabilities, damages, costs and expenses arising from or in
connection with any misrepresentation or breach of any representation, warranty,
covenant or agreement on the part of the Purchaser under this Agreement; (ii)
any and all actions, suits, claims, or legal, administrative, arbitration,
governmental or other proceedings or investigations against Stockholder that
relate to Purchaser or the business in which the principal event giving rise
thereto occurred after the Closing Date or which result from or arise out of any
action or inaction after the Closing Date of Purchaser or any officer, employee,
agent, representative or subcontractor of Purchaser; and (iii) any and all
actions, suits, proceedings, demands, assessments, judgments, costs and
expenses, including without limitation, reasonable legal fees and expenses,
incident to any of the foregoing or incurred in investigating or attempting to
avoid same or to oppose the imposition thereof, or in enforcing this indemnity.
Notwithstanding the foregoing in the event that a court of competent
jurisdiction having final adjudicative authority and from which no appeal is
available shall determine that Stockholder is not entitled to indemnification
then Stockholder shall not be entitled to recover its legal fees with respect to
such claim from the Purchaser.

         10.03. PROCEDURES FOR INDEMNIFICATION. Promptly after receipt by an
indemnified party under Section 10.01 or 10.02 of notice of the commencement of
any action for which indemnification may be available under Section 10.01 or
10.02 such indemnified party shall, if a claim in respect thereof is to be made
against an indemnifying party under such section, give notice to the
indemnifying party of the commencement thereof, but the failure so to notify the
indemnifying party shall not relieve it of any liability that it may have to any
indemnified party except to the extent the indemnifying party demonstrates that
the defense of such action is prejudiced thereby. In case any such action shall
be brought against an indemnified party and it shall give notice to the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall elect, to
assume the defense thereof with counsel reasonably satisfactory to such
indemnified party and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
section for any fees of other counsel or any other expenses, in each case
subsequently incurred by such indemnified party in connection with the defense
thereof, other than reasonable costs of investigation and costs and expenses of
legal counsel, if the indemnified party and the indemnifying party are both
parties to the action and the indemnified party has been advised by counsel that
there may be one or more defenses available to it and not available to the
indemnifying party. If an indemnifying party assumes the defense of such an
action, (a) no compromise or settlement thereof may be effected by the
indemnifying party without the indemnified party's consent (which shall not be
unreasonably withheld) unless (i) there is no finding or admission of any
violation of law or any violation of the rights of any person and no effect on
any other claims that may be made against the indemnified party and (ii) the
sole relief provided is monetary damages that are paid in full by the
indemnifying party and (b) the indemnifying party shall have no liability with
respect to any compromise or settlement thereof effected without its consent
(which shall not be unreasonably withheld). If notice is given to an
indemnifying part of the commencement of any action and it does not, within ten
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense thereof, the
indemnifying party shall be bound by any determination made in such action or
any compromise or settlement thereof effected by the indemnified party.
Notwithstanding

                                      -23-

<PAGE>
the foregoing, if an indemnified party determines in good faith that there is a
reasonable probability that an action may materially and adversely affect it or
its affiliates other than as a result of monetary damages, such indemnified
party may, by notice to the indemnifying party, assume the exclusive right to
defend, compromise or settle such action, but the indemnifying party shall have
the right to participate in such action and not be bound by any determination of
an action so defended or any compromise or settlement thereof effected without
its consent (which shall not be unreasonably withheld).

         10.04. SATISFACTION OF INDEMNIFICATION CLAIMS. All indemnification
obligations pursuant to Article X shall be paid within a reasonable period of
time after a claim for indemnification has been made and its validity finally
determined. In the event that Purchaser is entitled to indemnification from
Stockholder under this Article X, Stockholder shall have the right to satisfy
its indemnification obligation in any one or more of the following ways which
Stockholder shall elect by written notice to Purchaser (a "Satisfaction Notice")
given at any time prior to the time required for the first payment of such
obligation:

                  (a)      By a cash payment to Purchaser;

                  (b) By exchanging the Note for a new Note of Purchaser in a
         principal amount equal to $10,000,000 LESS any prepayments of principal
         theretofore made thereon by Purchaser LESS the amount of Stockholder's
         indemnification obligation specified by Stockholder in the Satisfaction
         Notice LESS any payments of interest theretofore made on the Note which
         payments are attributable to the reduction in principal amount
         specified in the Satisfaction Notice; and/or

                  (c) By assigning and delivering, contemporaneously with its
         giving the Satisfaction Notice, a number of shares USDL Common Stock
         (or any stock or other securities into which such Common Stock may be
         converted by reason of the anti-dilution provisions of the Note) which
         have an aggregate Market Value (as hereinafter defined) equal to the
         amount of Stockholder's indemnification obligation specified in the
         Satisfaction Notice. For purposes hereof, the "Market Value" of a share
         of USDL Common Stock shall mean the average closing price of such share
         on the principal securities market on which USDL Common Stock is then
         actively traded for the thirty (30) days immediately preceding the date
         the Satisfaction Notice is given to Purchaser.

If Stockholder does not timely give the Satisfaction Notice, Stockholder shall
be deemed to have elected to satisfy its indemnification by making payment
thereof in cash.

         10.05 LIMITATION ON CLAIMS. All claims for indemnification under this
Article X must be brought within eighteen (18) months of the Closing Date.

                                      -24-

                                   ARTICLE XI

                              RESTRICTIVE COVENANTS

          In consideration of Purchaser's purchase of the MediTek Stock and
Purchaser's payment of the Purchase Price, a portion of which is allocated to
the covenants included in this Article XI in accordance with this Agreement, and
such other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, the Stockholder covenants and agrees with the Purchaser
as follows:

         11.01. NON-COMPETITION. Stockholder agrees that for a period of five
(5) years following the Closing Date, it will not, directly or indirectly,
become or remain interested in, associated with, an owner, officer, director,
partner, shareholder, employee, agent, advisor or consultant in or indebted to
(other than as a recipient of service provided by any person, firm, corporation,
association, entity or organization) any person, firm, corporation, association,
entity or organization (collectively "Organization") (other than Purchaser or
its affiliates), that is engaged in the operation of diagnostic imaging
facilities or any other business similar to that of the businesses of Purchaser
on the Closing Date and/or any of the Purchaser's affiliates on the Closing
Date, that is operating in any form, manner or fashion, directly or indirectly,
within a radius of fifty (50) miles from a diagnostic imaging center facility
operated, or radiology facility managed, by Purchaser; PROVIDED, HOWEVER, that
nothing herein shall require Stockholder or its affiliates to cease operating
any such facility if the same, at the time it was organized or acquired by
Stockholder or such affiliate, was located more than 50 miles from any similar
facility operated or radiology facility managed, by Purchaser. Stockholder
acknowledges that a violation of this covenant will cause irreparable injury to
the Purchaser and its affiliates.

         11.02. NONSOLICITATION OF CUSTOMERS OR CLIENTS. Notwithstanding any
other provisions hereof, Stockholder shall not, for a period of five (5) years
following the Closing Date, at any time or in any manner, either directly or
indirectly, for its own behalf or for or on behalf of any Organization (other
than the Purchaser or its affiliates), solicit or attempt to solicit any
business similar to the Business from any customers or clients of MediTek and/or
Purchaser (as of the date of Closing). A "customer" or "client" shall mean any
Organization with which any of the foregoing have dealt or provided products or
services to.

         11.03. NONSOLICITATION OF EMPLOYEES. Except to the extent provided in
the existing terms of an employment agreement between Joseph Paul and Purchaser,
notwithstanding any other provision of this Agreement, Stockholder shall not for
a period of five (5) years following the Closing Date, either on its own behalf
or for or on behalf of any Organization (other than the Purchaser or its
affiliates), directly or indirectly, solicit, divert or otherwise encourage or
attempt to solicit, divert or otherwise encourage employees or agents of
MediTek, the Purchaser and/or any of their affiliates to enter into any
employment, consulting or advisory arrangement or contract with or to perform
any services for or on behalf of any Organization (other than the Purchaser
and/or any of its affiliates), or to enter into any kind of business, including
without limitation any business similar to either of the Business.

                                      -25-

<PAGE>
         11.04. REASONABLENESS. Stockholder has carefully read and considered
the provisions of this Article XI and, having done so, agrees that the
restrictions set forth herein (including without limitation, the time period of
restriction and the geographical areas of restriction) are fair and reasonable
and are reasonably required for the protection of the interests of the Purchaser
and its affiliates and to prevent irreparable harm to the foregoing.

         11.05. INJUNCTIVE RELIEF. The parties agree that the covenants of
Stockholder herein are material parts of the consideration received by the
Purchaser for entering into this Agreement and purchasing the MediTek Stock and
that any breach of this Article XI by Stockholder will result in irreparable
injury to the Purchaser and/or its affiliates. For that reason and because the
actual damages that might be sustained by the Purchaser and/or its affiliates
might be difficult, if not impossible, to ascertain and may not be adequate to
redress any injuries, the Purchaser and/or its affiliates shall, in addition to
any and all other remedies provided by law or otherwise, be entitled to an
injunction to prevent a breach or contemplated breach of any covenant of
Stockholder contained in this Article XI.

         11.06. SEVERABILITY. Each of the covenants in this Article XI is
independent and severable. Each such covenant shall remain in full force and
effect regardless of the enforceability of any other covenant herein, or of the
breach thereof by either party. If it shall be determined at any time by any
court of competent jurisdiction that any provision of this Article XI or any
portion thereof is unenforceable, or that any provision relating to the time
period or area of restriction exceeds the maximum time period or areas such
court deems reasonable, then such portions as shall have been determined to be
unreasonably restrictive or unenforceable or to exceed the maximum reasonable
time period or area of restriction shall thereupon be deemed to be so amended as
to make such restrictions reasonable in the determination of such court or to
become and thereafter be the maximum time period and/or areas which such court
deems reasonable and enforceable and the provision, as so amended, shall be
enforceable between the parties to the same extent as if such amendment had been
made prior to the date of any alleged breach of such provision.

                                   ARTICLE XII

                                OTHER AGREEMENTS

         12.01 REPRESENTATION ON PURCHASER'S BOARD OF DIRECTORS. (a) As soon as
practical but in no event later than 30 days after the Closing Date, Purchaser
shall cause Laurans A. Mendelson or such other person designated by Stockholder
to be elected to the Board of Directors of Purchaser, to serve until the
conclusion of the next annual meeting of stockholders in accordance with the
By-Laws of Purchaser. After the first one-year term, the obligations hereunder
shall be that Purchaser shall cause Mendelson or such designee to be nominated
for election to Purchaser's Board of Directors as part of the management slate
and to recommend to the stockholders his election to the Board of Directors of
Purchaser for a period of two (2) successive one-year terms after the original
one-year term.

shall be subject to the
                                      -26-

Promptly after first proposing a candidate, Stockholder shall furnish to
Purchaser such information as may be requested by Purchaser about Stockholder's
designee (i) that is required to be included in a Registration Statement under

Purchaser's securities.

         (c) Purchaser has applied for and will purchase a directors' and
officers' liability insurance policy which will cover each of its directors.
Such policy will be furnished to Stockholder prior to the appointment of
Stockholder's designee to the Board.

                     REGISTRATION AND SALE RIGHTS AGREEMENT

         THIS REGISTRATION AND SALE RIGHTS AGREEMENT is made as of July 1, 1996,
by and among U.S. Diagnostic Labs Inc. a Delaware corporation ("USDL" or the
"Company") and HEICO Corporation, a Florida corporation (the "Holder").

                                    RECITALS

         WHEREAS, the Company and the Holder are parties to the Stock Purchase
Agreement of even date herewith (the "Purchase Agreement") relating to the
purchase by the Company of the stock of MediTek Health Corporation, the
consideration of which consists in part of a note (the "Note") convertible into
Common Stock, $.01 par value, of the Company ("USDL Common Stock" such
definition to include any other stock or equity securities issuable by reason of
the anti-dilution provisions of the Note);

         WHEREAS, in order to induce the Holder to enter into the Purchase
Agreement and to induce the Company to purchase such stock pursuant to the
Purchase Agreement, the Holder and the Company hereby agree that this Agreement
shall govern (i) the rights of the Holder to cause the Company to register
shares of the USDL Common Stock issuable to the Holder upon the conversion of
the Note, (ii) the terms of the voting proxy granted by the Holder and (iii)
certain other matters as set forth herein;

         NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

         1. REGISTRATION RIGHTS. The Company covenants and agrees with respect
to the USDL Common Stock issuable upon conversion of the Note, as follows:

         1.1      DEFINITIONS.  For purposes of this Agreement:

         (a) The term "Act" means the Securities Act of 1933, as amended, or any
successor act.

         (b) The term "Holder" means any person owning or having the right to
acquire Registrable Securities or any assignee thereof in accordance with this
Agreement.

         (c) The term "1934 Act" shall mean the Securities Exchange Act of 1934,
as amended, or any successor act.

         (d) The terms "register", "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document under the Act, and the declaration or order of effectiveness of
such registration statement or document.
                                       -1-

<PAGE>
         (e) The term "Registrable Securities" means the USDL Common Stock
issuable upon conversion of the Note, excluding (i) any Registrable Securities
sold by a person in a transaction in which his rights under this Section 1 are
not assigned or are assigned in violation of this Agreement and (ii) any
Registrable Securities that have already been registered under the Act or which
are freely transferable without registration under the Act due to the lapse of
time or otherwise and which are not subject to any sales volume limitation under
Rule 144 promulgated by the SEC under the Act ("Rule 144") based on the Holder's
holding's of Registrable Securities.

         (f) The number of shares of "Registrable Securities then outstanding"
for the Company shall be determined by the number of shares of USDL Common Stock
outstanding which are, and the number of shares of USDL Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities.

         (g) The term "SEC" shall mean the Securities and Exchange Commission.

         1.2      REQUIRED REGISTRATION.

         (a) The Company shall file with and use its best efforts to cause to be
declared effective by, the SEC on or before January 1, 1997 a registration
statement on Form S-3 under the Act or such other form that is available to the
Company covering the registration of the Registrable Securities.

         (b) Notwithstanding the foregoing, the Company shall be permitted to
postpone the filing of any registration pursuant to this Section 1.2 if during
the period from November 1, 1996 to January 31, 1997, the Company is engaged, or
has fixed plans to engage prior to February 28, 1997, in a registered public
offering in which Registrable Securities will not be included, or is engaged, or
has fixed plans to engage within sixty (60) days of January 1, 1997, in a
material acquisition or any other activity that, in the good faith determination
of the Board of Directors of the Company, would require premature disclosure of
such activity to the material detriment of the Company, then the Company may at
its option direct that such filing be delayed for a period not in excess of
sixty (60) days from the effective date of such offering, or the date of
commencement of such other material activity, as the case may be, provided in
any case that the effective date of such registration statement shall not be
later than March 1, 1997.

         1.3 "PIGGY-BACK" REGISTRATION RIGHTS. If (but without any obligation to
do so), during the three (3) year period commencing on January 1, 1997, the
Company proposes to register any of its Common Stock under the Act (a) in
connection with a public offering by the Company solely for cash or (b) on
behalf of stockholders other than the Holder in an underwritten offering (other
than a registration on Form S-8 or S-4 or relating solely to the sale of
securities to participants in a Company stock plan, or a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given
                                       -2-

<PAGE>
within twenty (20) business days after mailing of such notice by the Company,
the Company shall, subject to the limitations set forth in this Agreement
(including the limitations of Section 1.7), include in the Company's
registration statement under the Act all of the Registrable Securities that each
such Holder has requested to be registered; provided, however, that (i) the
Company shall not be obligated to effect any registration pursuant to this
Section 1.3 after the Company has effected two (2) such registrations in which
Registrable Securities are included and each such registration has been declared
or ordered effective, (ii) the Company need not include any Registrable
Securities in any registration statement relating to an underwritten offering if
such Registrable Securities are included in a then current registration
statement, and (iii) nothing in this Section 1.3 shall prevent the Company from
at any time abandoning or delaying any such registration without obligation to
any Holder, provided that such abandoned registration shall not be considered
one of the registrations referred to in clause (i) of this sentence.

         1.4 OBLIGATIONS OF THE COMPANY. Whenever required under this Section 1
to effect the registration of any Registrable Securities or to include
Registrable Securities in a registration statement, the Company shall, as
expeditiously as reasonably possible:

         (a) Prepare and file with the SEC a registration statement with respect
to such Registrable Securities and use its reasonable best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for a period of two years or such shorter
period as required until the distribution contemplated in the Registration
Statement has been completed; provided, however, that such period shall be
extended for a period of time equal to the period the Holder refrains from
selling any securities included in such registration at the request of an
underwriter of Common Stock (or other securities) of the Company.

         (b) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

         (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

         (d) Use its reasonable best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Act.

         (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing
                                       -3-

<PAGE>
underwriter of such offering. Each Holder participating in such underwriting
shall also enter into and perform its obligations under such an agreement.

         (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

         (g) Cause all such Registrable Securities registered pursuant hereunder
to be listed on each securities exchange on which similar securities issued by
the Company are then listed.

         (h) The Company covenants and agrees to: (i) make and keep available
adequate current public information as such is understood and defined in Rule
144 under the Act; and (ii) file with the SEC in a timely manner all reports and
other documents required of the Company under the 1934 Act.

         1.5 FURNISH INFORMATION. It shall be a condition precedent to the
obligation of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding the Holder, the
Registrable Securities held by the Holder, and the intended method of
disposition of such securities as shall be required to effect the registration
of such Holder's Registrable Securities.

         1.6 EXPENSES OF REGISTRATION. The Company shall bear and pay all
expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to Section
1 for each Holder, including all registration, filing, and qualification fees,
printers and accounting fees relating or apportionable thereto, but excluding
underwriting discounts and commissions relating to Registrable Securities;
provided, however, that the Company shall not bear the cost of any professional
fees or costs of accounting, financial or legal advisors to the Holder.
Notwithstanding the foregoing, Holder shall pay all registration expenses which
such Holder is required to pay under applicable law.

         1.7 UNDERWRITING REQUIREMENTS. In connection with any offering
involving an underwriting of USDL Common Stock, the Company shall not be
required under Section 1.3 to include any of the Holders' securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it (or by other persons
entitled to select the underwriters), and then only in such quantity as the
underwriters determine in their sole discretion will not jeopardize the success
of the offering by the Company. If the total amount of securities, including
Registrable Securities, requested by stockholders to be included in such
offering exceeds the amount of securities to be offered, other than by the
Company, that the underwriters determine in their sole discretion is compatible
with the success of the offering, then the Company shall be required to include
in the offering only
                                       -4-

<PAGE>
that number of such securities, if any, including Registrable Securities, which
the underwriters determine in their sole discretion will not jeopardize the
success of the offering (the securities so included to be apportioned pro rata
among the selling stockholders according to the total amount of securities
entitled to be included therein owned by each selling stockholder or in such
other proportions as shall mutually be agreed to by such selling stockholders,
provided that no other stockholder shall be permitted to include a greater
proportion of their shares of USDL Common Stock in such registration statement
than Holder desires to include therein).

         1.8 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this Section 1:

         (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, each of Holder's directors and officers, any underwriter
(as defined in the Act) for such Holder and each person, if any, who controls
such Holder or underwriter within the meaning of the Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the Act, or the 1934 Act, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereof) arise out of or
are based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, or any rule or regulation promulgated under
the Act, and the Company will pay to each such Holder, underwriter or
controlling person any reasonable legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.8(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld), nor shall the Company be liable in any such case for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
information furnished for use in connection with such registration by any such
Holder, underwriter or controlling person.

         (b) To the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company, each of the Company's directors, each of the
Company's officers who has signed the registration statement, each person, if
any, who controls the Company within the meaning of the Act, any underwriter,
any other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Act, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereto) arise out of or are
based upon any Violation, in each case to the extent (and only to the extent)
that such Violation occurs in reliance upon and in conformity with information
furnished by such Holder for use in connection with such registration; and each
such
                                       -5-

<PAGE>
Holder will pay any legal or other expenses reasonably incurred by any person
intended to be indemnified pursuant to this subsection 1.8(b), in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
subsection 1.8(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder (which consent shall not be unreasonably withheld);
provided, that, in no event shall the aggregate liability for indemnification by
any Holder under this subsection 1.8(b) exceed the gross proceeds from the
offering relating to securities sold by such Holder.

         (c) Promptly after receipt by an indemnified party under this Section
1.8 of notice of the commencement of any action (including any governmental
action), such indemnified party shall, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.8, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly notified, to assume the defense thereof with counsel selected by the
indemnifying party and approved by the indemnified party (whose approval shall
not be unreasonably withheld); provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.8, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.8.

         (d) If the indemnification provided for in this Section 1.8 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified
party and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

         (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control.

         (f) The obligations of the Company and Holders under this Section 1.8
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

                  2.       OTHER AGREEMENTS.

         2.1 VOTING AGREEMENT AND PROXY. The Holder hereby grants to Jeffrey A.
Goffman, Chairman of the Board of the Company, an irrevocable proxy (the
"Proxy") to vote the Registrable Securities in the election of directors of the
Company and in any vote of stockholders involving proposed changes of control,
mergers and other similar extraordinary transactions. The Proxy will be voted at
the direction of a majority of the Board of Directors of the Company, but in any
event will be voted for the election of HEICO Corporation's designee on the
Company's Board of Directors. The Company shall also cause (to the extent
permitted by law) each of its officers and directors and each of the Company's
officers' and directors' designees to vote any securities over which they have
authority to vote (whether by proxy, voting trust or otherwise) for the election
of the HEICO Corporation's designee on the Company's Board of Directors during
the term of the Proxy. The Proxy shall have a term of three years, but subject
to Section 2.2, shall automatically terminate upon the sale of such shares by
Holder to an unaffiliated third party. Holder agrees to execute any documents
necessary to enforce the provisions of this section.

         2.2 RESTRICTION ON TRANSFER. Until January 1, 1997, the Holder agrees
not to directly or indirectly sell, offer to sell, contract to sell (including,
without limitation, any short sale), grant any option to purchase or otherwise
transfer or dispose of any Registrable Securities held by it except (i) in a
private transaction in which the transferee agrees to be bound by the Proxy, or
(ii) in a pro-rata distribution by Holder to its stockholders in a transaction
that would not require registration of such shares under the Act prior to the
filing required to be made pursuant to Section 1.2 hereof. Thereafter until June
30, 1998, Holder shall be permitted to sell the greater of one-quarter (1/4) of
the Registrable Securities during each calendar month on a noncumulative basis
or the number of shares which, but for the absence of the required holding
period, the Holder would be entitled to sell pursuant to Rule 144 (provided
always that such sale is pursuant to an effective registration statement under
the Act or qualifies for an exemption under the Act). This Section 2.2 shall be
binding upon any transferee of the Registrable Securities and the certificates
shall bear a legend to such effect. In addition, prior to a distribution by
Holder to its stockholders, if any, any person which shall be entitled to
receive shares of USDL Common Stock constituting two percent (2%) or more of
USDL Common Stock outstanding at such time shall agree in writing (a) not to
sell in any month more than the amount which Holder could sell pursuant to the
preceding sentence, and (b) to the terms of the Proxy described in Section 2.1.
In order to enforce the foregoing covenants, the Company may impose

                                       -7-
<PAGE>
stop-transfer instructions with respect to the Registrable Securities of each
Holder (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

         2.3 SELLING AGENT; BLOCK TRADES. If a Holder desires to sell any
Registrable Securities in an open market transaction prior to June 30, 1998,
such shares shall be made through a broker-dealer reasonably acceptable to the
Company and the Holder (a "Sales Agent"). Prior to the appointment of a Sales
Agent, such Sales Agent shall agree, if requested by the Company, to execute any
such sales in a manner which does not have a material adverse impact on the
market for the USDL Common Stock. Any such sales shall be on terms to be
negotiated between the Sales Agent and the Holder. Notwithstanding the
foregoing, privately negotiated "block" trades (i.e., a sale of at least 50,000
shares) shall be permitted to be made without the Sales Agent; provided that
such transfer is made subject to the Proxy and the provisions of the second
sentence of Section 2.2.

         2.4 SALES TO QIB'S. Notwithstanding anything to the contrary contained
in this Agreement, the restrictions on transfer and proxy/voting provisions of
this Agreement, including without limitation the provisions of Section 2.1, 2.2
and 2.3, shall not apply to any transfer of USDL Common Stock by a Holder to a
"Qualified Institutional Buyer", as such term is defined in Rule 144A of the SEC
under the Act.

                  3.       MISCELLANEOUS.

         3.1 SUCCESSORS AND ASSIGNS. Except as otherwise provided in Section 3.2
below and elsewhere herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective successors and
assigns of the parties (including transferees of any shares of Registrable
Securities). Nothing in this Agreement, express or implied, is intended to
confer upon any party other than the parties hereto or their respective
successors and assigns any rights, remedies, obligations, or liabilities under
or by reason of this Agreement, except as expressly provided in this Agreement.

         3.2 TRANSFER OF RIGHTS. The rights granted to the Holder pursuant to
Section 1 may not be transferred or assigned except (a) in connection with the
transfer or assignment of the Note, (b) to a transferee or assignee of at least
25% of the Registrable Securities or (c) to a Qualified Institutional Buyer.

         3.3 GOVERNING LAW. This Agreement shall be governed by and construed
under the laws of the State of Florida as applied to agreements among Florida
residents entered into and to be performed entirely within Florida without
regard to principles of conflicts of law.

         3.4 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall be deemed an original, but all of which together shall constitute
one and the same instrument.

this Agreement and the balance of the Agreement shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its
terms. The parties hereto shall endeavor to replace any such unenforceable
provision or provisions with a valid and enforceable provision or provisions
which shall have substantially the same economic effect as the unenforceable
provision or provisions.
