ITEM 2.     ACQUISITION OR DISPOSITION OF ASSETS

      On September 30, 1997 Henley Healthcare, Inc., a Texas corporation (the
"Company"), entered into an agreement with Cybex International, Inc., a New York
corporation ("Cybex"), whereby the Company purchased certain assets of (and
assumed certain liabilities associated with) the isokinetic rehabilitation
product line (the "Product Line") of Cybex for an estimated purchase price of
approximately $3.2 million. The assets acquired consist of tangible personal
property including machinery, equipment, furniture and fixtures; general
intangibles; contracts; intellectual property; business licenses; inventory; and
prepaid expenses.

      The purchase price was paid in cash which the Company obtained pursuant to
an amendment to its Amended and Restated Loan Agreement (the "Amended Loan
Agreement") entered into with Comerica Bank - Texas, a Texas banking corporation
("Comerica"). The Amended Loan Agreement with Comerica provides for a revolving
loan which permits borrowings up to $8,000,000 pursuant to a borrowing base
calculation derived from the Company's accounts receivable and inventory. In
connection with the Amended Loan Agreement, the Company paid off its Term Note A
with Comerica in the amount of $893,000 and issued a substitute Term Note A in
the amount of $1,430,000. The revolving loan's maturity date is February 1,
1999, while the maturity date of the $1,430,000 Term Note A is September 30,
2002. All of the borrowings from Comerica are secured by substantially all of
the assets of the Company including the assets acquired from Cybex. The Amended
Loan Agreement also contains a number of affirmative covenants, negative
covenants and financial covenants with which the Company must comply including a
minimum tangible net worth, leverage ratio, working capital ratio, fixed charge
ratio and interest coverage ratio.

      In connection with the Amended Loan Agreement with Comerica relating to
the acquisition of the Product Line from Cybex, the Company entered into an
amendment to the Subordination Agreement (the "Subordination Amendment") by and
among Maxxim Medical, Inc. ("Maxxim"), Comerica and the Company. Pursuant to the
Subordination Amendment, the maximum amount of the Company's debt with Comerica
that can be issued senior to Maxxim's Convertible Subordinated Promissory Note
from the Company (the "Maxxim Note) was increased from $10,000,000 to
$12,000,000. In exchange for Maxxim's execution of the Subordination Amendment,
the Company entered into a note modification agreement with Maxxim in which the
Conversion Price (as defined in the Maxxim Note) was reduced from $3.00 to
$2.00. The modification of the Maxxim Note increases the number of shares of the
Company's common stock, par value $.01 per share ("Common Stock"), beneficially
owned by Maxxim from 2,333,333 to 3,500,000 which upon conversion would
represent approximately 53% (compared to approximately 43% prior to the
adjustment of the conversion price) of the currently issued and outstanding
Common Stock. The Maxxim Note is convertible into Common Stock at any time at
Maxxim's option.

                                     2

The Company intends to continue the manufacturing and marketing of the Product
Line and, after a short transition period, will move the manufacturing activity
from the Cybex facilities in Ronkonkoma, New York to the Company's manufacturing
plants in Sugar Land and Belton, Texas.

      1.10 OUTSTANDING WARRANTY OBLIGATIONS. Buyer hereby assumes, as of the
Closing Date, all of Seller's Outstanding Warranty Obligations. Buyer further
agrees to respond to and fulfill the Outstanding Warranty Obligations in a
timely manner and in accordance with the terms and provisions of Seller's
standard product warranty (the "Standard Product Warranty," a copy of which is
attached hereto as SCHEDULE 1.10), and the unwritten warranty with regard to the

part of SCHEDULE 1.10). In addition, Buyer agrees to continue to provide
replacement parts and/or repair services with respect to the Product Line, at
Buyer's standard rates, following the expiration of any warranty period for a
commercially reasonable length of time. Seller acknowledges that it is

<PAGE>
prior to the Closing Date, and Seller agrees to so cooperate with Buyer
concerning Claims brought against Buyer involving products in the Product Line
sold after to the Closing Date.

      1.11 WARRANTY SERVICE AGREEMENT. As a condition precedent to the Buyer's
obligations under this Agreement, the Buyer, on or before the Closing Date,

Agreement") to replace the Statement of Work to Technical Support Agreement

any way be responsible or liable to Seller for any nonpayment of or failure to
collect the Accounts Receivable.

      1.15 OFFSET. If Buyer is entitled to indemnification pursuant to the
provisions of Article 4, Buyer at its option shall be entitled to offset the
amount of any such expenses or Claims, respectively, against any payments
otherwise due to Seller under this Agreement or any payments due under the
Trademark License Agreement. The rightful exercise of the right of offset
hereunder shall not constitute a breach or default of any provision requiring
payment of sums so offset, or relieve the party against whom such right of
offset is exercised from performing its obligations thereunder.

      1.16 FURTHER ASSURANCES. From time to time, as and when requested by any
party hereto, any other party hereto shall execute and deliver, or cause to be
executed and delivered, such documents and instruments and shall take, or cause

leased and operated by it. Seller is duly qualified or licensed to do business
and is in good standing as a foreign corporation authorized to do business in
all jurisdictions in which the character of the properties owned or the nature

information furnished by Buyer or its representatives to Seller and any of its

                                   ARTICLE 4

                                INDEMNIFICATION

      4.1 INDEMNIFICATION BY SELLER. Seller shall indemnify, defend and hold
harmless Buyer and its officers, directors, employees, agents and shareholders,
against and with respect to any and all Claims that such indemnitees shall incur
or suffer, which arise, result from or relate to (i) any breach of, or failure
by Seller to perform, any of Seller's representations, warranties, covenants or
agreements in this Agreement or in any schedule, certificate, exhibit or other

and (ii) any and all Retained Liabilities of Seller, including, without
limitation, any tax liabilities, with respect to which Seller or any other
Person at any time asserts a Claim therefor against the Buyer ("Liability

      4.2 INDEMNIFICATION BY BUYER. Buyer shall indemnify, defend and hold
harmless Seller and its officers, directors, employees, agents and shareholders,
against and with respect to any and all Claims that such indemnitees shall incur
or suffer, which arise, result from or relate to (i) any breach of, or failure

instrument furnished to Seller by Buyer under this Agreement ("Breach Claims"),
and (ii) any and all liabilities of Buyer relating to the Outstanding Warranty
Obligations with respect to which any other Person at any time asserts a Claim

      4.3   INDEMNIFICATION PROCEDURE.

            4.3.1 Promptly upon the receipt of notice of any third-party (I.E.,
      one who is not a party to this Agreement) Claim, judicial or otherwise,
      with respect to any matter as to which indemnification may be claimed
      under this Article 4, the indemnified party shall give written notice
      thereof to the indemnifying party together with such information
      respecting such matter as the indemnifying party shall then have; PROVIDED
      HOWEVER, that the failure of the indemnified party to give notice as
      provided herein shall not relieve the indemnifying party of any
      obligations, to the extent the indemnifying party is not materially
      prejudiced thereby. If indemnification is sought with respect to a
      third-party Claim asserted or brought against an indemnified party, the
      indemnifying party shall be entitled to participate in and to assume the
      defense thereof, jointly with any other indemnifying party similarly
      notified, to the extent that it may wish, with counsel reasonably
      satisfactory to such indemnified party. After such notice from the
      indemnifying party to such indemnified party of its election to so assume
      the defense of such a third-party Claim, the indemnifying party shall not
      be liable to such indemnified party for any legal or other expenses
      subsequently incurred by the latter in connection with the defense
      thereof, other than reasonable and necessary costs of investigation,
      unless the indemnifying party has failed to assume and diligently
      prosecute the

                                      11
<PAGE>
      defense of such third-party Claim and to employ counsel reasonably
      satisfactory to such indemnified Person. An indemnifying party who elects
      not to assume the defense of a third-party Claim shall not be liable for
      the fees and expenses of more than one counsel in any single jurisdiction
      for all parties indemnified by such indemnifying party with respect to
      such Claim or with respect to Claims separate but similar or related in
      the same jurisdiction arising out of the same general allegations.
      Notwithstanding any of the foregoing to the contrary, the indemnified
      party will be entitled to select its own counsel and assume the defense of
      any action brought against it if the indemnifying party fails to select
      counsel reasonably satisfactory to the indemnified party or if counsel
      fails to diligently prosecute, the expenses of such defense to be paid by
      the indemnifying party. No indemnifying party shall consent to entry of
      any judgment or enter into any settlement with respect to a claim without
      the consent of the indemnified party, which consent shall not be
      unreasonably withheld. No indemnified party shall consent to entry of any
      judgment or enter into any settlement of any such action the defense of
      which has been assumed by an indemnifying party without the consent of
      such indemnifying party, which consent shall not be unreasonably withheld.

            4.3.2 If any party becomes aware of a fact, circumstance, claim,
      situation, demand or other matter (other than a third-party Claim) for
      which it or any other indemnified party has been indemnified under this
      Article 4 and which has resulted or could result in a Claim being owed to
      the indemnified party by the indemnifying party, the indemnified party
      shall give prompt written notice to the indemnifying party of the Claim,
      stating the nature and basis of the Claim and the amount claimed
      thereunder, together with supporting information to the Claim, if any. If
      the indemnifying party does not notify the indemnified party within 30
      days from the date such Claim notice is given that it disputes the Claim,
      the amount of the Claim shall conclusively be deemed to be a liability of
      the indemnifying party hereunder.

            4.3.3 Payments of all amounts owing hereunder with respect to any
      Claim shall be made immediately after the settlement between the parties
      of the third party Claim.

      4.4 INDEMNIFICATION THRESHOLD AND LIMITATIONS. Any request for
indemnification by an indemnified party under the indemnification procedures of
this Article 4 regarding the breach of any representation or warranty under this
Agreement must be asserted by such indemnified party prior to the expiration of
the applicable survival period as set forth in Section 6.5. Notwithstanding any
provision to the contrary contained in this Agreement, neither Buyer nor Seller
shall make any request for indemnification against the other party for any
Breach Claim under this Agreement until the dollar amount of all losses to such
other party for such Breach Claims suffered after the Closing, shall exceed in
the aggregate the amount of $300,000, and, if such amount is exceeded, Buyer or
Seller, as the case may be, shall be required to pay the entire amount of such
aggregate loss to the other party for all such Breach Claims; PROVIDED, HOWEVER,
that a party's obligation and liability for any and all Breach Claims shall not
exceed in the aggregate an amount equal to the purchase price set forth in
Section 1.3. Without regard to the above-mentioned $300,000 aggregate Claim
threshold: (i) Seller shall reimburse Buyer for any and all Liability Claims,
and (ii) Buyer shall reimburse Seller for any and all Warranty Claims.

                                   ARTICLE 5

                           NON-COMPETITION AGREEMENT

      As used in this Article 5, any reference to "Buyer" or "Seller" shall mean
and include their respective Affiliates.

      5.1 SELLER COVENANT NOT TO COMPETE. For a two-year period beginning on the
Closing Date, Seller shall not directly or indirectly, engage or invest in,
finance, own, manage, operate, control or participate in the ownership,
management, operation or control of, be employed by, associated or in any manner
connected with, render services or advice to, or assist (whether or not for
compensation), any Competing Business (as defined below); PROVIDED HOWEVER, that
this Section 5.1 shall not preclude the Seller or its Affiliates from (a)
investing in up to an aggregate of 5% of the securities of any enterprise
engaged in a Competing Business (but without otherwise participating in the
activities of such enterprise) if such securities are listed on any United
States national or regional securities exchange or have been registered under
Section 12(g) of the Securities Exchange Act of 1934, provided that the Seller
and its Affiliates combined do not purchase or hold (directly or indirectly) an
aggregate equity interest of more than 5% in any such enterprise, or (b)
pursuant to Seller's Distributor Agreement.

      5.2 COVENANTS NOT TO INTERFERE OR HIRE. For a two-year period beginning on
the Closing Date, neither Seller nor Buyer shall directly or indirectly, either
as principal, agent, independent contractor, consultant, director, officer,
employee, employer, advisor (whether paid or unpaid), stockholder, partner or in
any other individual or representative capacity whatsoever, either for their own
benefit or for the benefit of any other Person, either (i) hire, attempt to
hire, contact or solicit with respect to hiring any employee (not including
independent sales representatives) of the other party hereto as of the Closing
Date, (ii) induce or otherwise counsel, advise or encourage any employee of the
other party as of the Closing Date to leave the employment of that party, or
(iii) induce any distributor, vendor, supplier, representative or agent of or to
the other party to terminate or modify its relationship with that party;
PROVIDED, HOWEVER, that the covenants in this Section shall not prohibit the
Buyer from hiring any of the employees listed on SCHEDULE 5.2, nor shall the
hiring of any such employees constitute a breach of such covenants.

      5.3 NECESSITY AND REASONABLENESS. The parties hereto hereby specifically
acknowledge, agree and represent to each other as a material inducement for
their entering into this Agreement:

            5.3.1 the covenants and agreements of the parties in this Article 5
      are necessary and essential to the protection of the business which will
      be conducted by the parties after the Closing Date, and to enable the
      parties to realize and derive all of the benefits, rights and expectations
      associated with this Agreement;

            5.3.2 Buyer will suffer great loss and irreparable harm if the
      Seller directly or indirectly enters into a Competing Business;

            5.3.3 the temporal and other restrictions contained in this Article
      5 are in all respects reasonable and necessary to protect the business
      goodwill, trade secrets, prospects and other business interests of Buyer
      in respect of the Seller;

                                      13
<PAGE>
            5.3.4 the enforcement of this Agreement in general, and of this
      Article 5 in particular, will not work an undue or unfair hardship on
      either party or otherwise be oppressive to it, it being specifically
      acknowledged and agreed by the Seller that it has other business interests
      and opportunities which will provide it adequate means of support if the
      provisions of this Article 5 are enforced;

            5.3.5 the enforcement of this Agreement in general, and of this
      Article 5 in particular, will neither deprive the public of needed goods
      or services nor otherwise be injurious to the public; and

            5.3.6 good, independent and valuable consideration exists for the
      agreement of the parties to be bound by the covenants and agreements
      contained in this Article 5.

      5.4 ENFORCEMENT. Because of the unique nature of the Assets and the
Product Line, the business to be conducted and further developed by Buyer
therewith, and the confidential and proprietary information relating thereto,
the Seller acknowledges, understands and agrees that Buyer will suffer immediate
and irreparable harm if the Seller or its Affiliates fail to comply with any of
their respective obligations under this Article 5 and that monetary damages will
be inadequate to compensate Buyer for such breach. Accordingly, the Seller
agrees that Buyer shall, in addition to any other remedies available to it at
law or in equity, be entitled to temporary, preliminary, and permanent
injunctive relief and specific performance to enforce the terms of this Article

will expire on June 1, 1999.

      6.6 KNOWLEDGE, GENDER AND CERTAIN REFERENCES. Unless otherwise provided
for herein, a representation or statement made herein to the knowledge of Seller
or Buyer shall mean the actual knowledge of Seller or Buyer. Unless otherwise
specified, all references herein to days, weeks, months or years shall be to
calendar days, weeks, months or years. Capitalized terms defined in this
Agreement are equally applicable to both their singular and plural forms.
Whenever the context requires, the gender of all words used herein shall include
the masculine, feminine and neuter. References to Articles or Sections shall be
to Articles or Sections of this Agreement unless otherwise specified. The
headings and captions used in this Agreement are solely for convenient reference
and shall not affect the meaning or interpretation of any article, section or
paragraph herein, or this Agreement. The terms "hereof," "herein" or "hereunder"
shall refer to this Agreement as a whole and not to any particular article,
section or paragraph. The terms "including" or "include" are used herein in an
illustrative sense and not to limit a more general statement. When computing
time periods described by a number of days before or after a stated date or
event, the stated date or date on which the specified event occurs shall not be
counted and the last day of the period shall be counted.

      6.7 SUCCESSOR AND ASSIGNS. This Agreement shall bind, inure to the benefit
of and be enforceable by the parties hereto and their respective successors and
permitted assigns, and if an individual, by his executors, administrators, and
beneficiaries of his estate by will or the laws of descent and distribution.
This Agreement and the rights and obligations hereunder shall not be assignable
or delegable by any party; provided, however, that Buyer shall be entitled to

      6.8 APPLICABLE LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Texas and of the United States
applicable in Texas, excluding, however, any rule of conflict-of-laws that would
direct or refer the resolution of any issue to the laws of any other
jurisdiction. Each party hereto hereby acknowledges and agrees that it has
consulted legal counsel in connection with the negotiation of this Agreement and
that it has bargaining power equal to that of the other parties hereto in
connection with the negotiation and execution of this Agreement. Accordingly,
the parties hereto agree that the rule that an agreement shall be construed
against the draftsman shall have no application in the construction or
interpretation of this Agreement.

      6.9 SEVERABILITY; JUDICIAL MODIFICATION. If any term, provision, covenant,
or restriction of this Agreement is held by a court of competent jurisdiction to
be invalid, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions shall remain in full force and effect

                                      18
<PAGE>
and shall in no way be affected, impaired or invalidated. It is hereby
stipulated and declared to be the intention of the parties that they would have
executed this Agreement had the terms, provisions, covenants and restrictions
which may be hereafter declared invalid, void, or unenforceable not initially
been included herein. If a court of competent jurisdiction determines that the
length of time or any other restriction, or portion thereof, set forth in
Article 5 is overly restrictive and unenforceable, the court may reduce or
modify such restrictions to those which it deems reasonable and enforceable
under the circumstances, and the parties agree to request the court to exercise
such power, and, as so reduced or modified, the parties hereto agree that the
restrictions of Article 5 shall remain in full force and effect, shall be
enforceable and shall be enforced.

      6.10 AMENDMENT AND ENTIRETY. This Agreement, the Ancillary Agreements, and
any exhibits hereto or thereto, may be amended, modified, or superseded only by
written instrument executed by all parties hereto. This Agreement sets forth the
entire agreement and understanding of the parties with respect to the
transactions contemplated hereby and supersedes all prior agreements,
arrangements, and understandings relating to the subject matter hereof. In the
event of any conflict or inconsistency between the provisions of this Agreement
and the contents or provisions of any schedule or exhibit hereto, the provisions
of this Agreement shall control. Except as expressly permitted by this
Agreement, the contents of schedules and exhibits hereto shall not be deemed to
negate or modify any representation, warranty, covenant or agreement contained
in this Agreement. Without limiting the generality of the preceding sentence,
any representation, warranty, covenant or other agreement contained in any
document, instrument or agreement delivered pursuant hereto or entered into in
connection herewith is made in addition to, and not in lieu of, any
representation, warranty, covenant or other agreement contained herein.

      6.11 RIGHTS OF PARTIES. Nothing in this Agreement, whether express or
implied, is intended to confer any rights or remedies under or by reason of this
Agreement on any Persons other than the parties hereto and their respective
successors and assigns, nor shall any provision give any third Persons any right
of subrogation or action over against any party to this Agreement. Without
limiting the generality of the foregoing, it is expressly understood that this
Agreement does not create any third party beneficiary rights.

      6.12 TIME OF ESSENCE. Time is of the essence in the performance of this
Agreement.

      6.13 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, and by facsimile signature, each of which shall be deemed an
original and all which together shall constitute one and the same instrument.

            2.4.4. TERM NOTE B ANNUAL CALL PROVISIONS. Notwithstanding anything
contained in this Agreement, Term Note B or any of the Loan Documents (and
without limiting any other provision contained in any of them for the
acceleration of the maturity of Term Note B), beginning with April 30, 2001, and
with respect to each April 30 occurring thereafter, the Bank, in its sole and
absolute discretion, with or without cause, may elect to accelerate the final
stated maturity of Term Note B to any such April 30 date by giving written
notice to the Borrower of such election no later than 30 days prior to the
applicable anniversary date.

      2.5. MAXIMUM RATE. The following provisions shall control this Agreement
and the Note:

            (a) No agreements, conditions, provision or stipulations contained
      in this Agreement, any Note, any of the other Loan Documents or in any
      other agreement between the Borrower and the Bank, or the occurrence of an
      Event of Default, or the exercise by the Bank of the right to accelerate
      the payment of the maturity of principal and interest, or to exercise any
      option whatsoever contained in this Agreement or any other agreement
      between the Borrower and the Bank, or the arising of any contingency
      whatsoever, shall entitle the Bank to collect, in any event, interest
      exceeding the maximum rate of nonusurious interest allowed from time to
      time by applicable state or federal laws as now or as may hereinafter be
      in effect (the "MAXIMUM LEGAL RATE") and in no event shall the Borrower be
      obligated to pay interest exceeding such Maximum Legal Rate, and all
      agreements, conditions or stipulations, if any, which may in any event or
      contingency whatsoever operate to bind, obligate or compel any Obligor to
      pay a rate of interest exceeding the Maximum Legal Rate shall be without
      binding force or effect, at law or in equity, to the extent only of the
      excess of interest over such Maximum Legal Rate. In the event any interest
      is charged in excess of the Maximum Legal Rate (the "EXCESS"), the
      Borrower acknowledges and stipulates that any such charge shall be the
      result of an accidental and bona fide error, and such Excess shall be,
      first, applied to reduce the principal of any obligations due, and,
      second, returned to the Borrower, it being the intention of the parties
      hereto not to enter at any time into an usurious or otherwise illegal
      relationship. The parties hereto recognize that with fluctuations in the
      Prime Rate from time to time announced by the Bank such an unintentional
      result could inadvertently occur. By the execution of this Agreement, the
      Borrower covenants that the credit or return of any Excess shall
      constitute the acceptance by the Borrower of such Excess, and the Borrower
      shall not seek or pursue any other remedy, legal or equitable, against the
      Bank based, in whole or in part, upon the charging or receiving of any
      interest in excess of the Maximum Legal Rate. For the purpose of
      determining whether or not any Excess has been contracted for, charged or
      received by the Bank, all interest at any time contracted for,

                                    -19-
<PAGE>
      charged or received by the Bank in connection with the Borrower's
      obligations shall be amortized, prorated, allocated and spread in equal
      parts during the entire term of this Agreement. If at any time the rate of
      interest payable hereunder with respect to any Note shall be computed for
      such Note on the basis of the Maximum Legal Rate, any subsequent reduction
      in the Contract Rate shall not reduce such interest thereafter payable
      hereunder with respect to such Note below the amount computed on the basis
      of the Maximum Legal Rate until the aggregate amount of such interest
      accrued and payable under this Agreement equals the total amount of
      interest which would have accrued if such interest had been at all times
      computed solely on the basis of the Contract Rate for such Note.

            (b) Unless preempted by federal law, the rate of interest from time
      to time in effect hereunder shall not exceed the "INDICATED RATE CEILING"
      from time to time in effect under Chapter 1 of the Texas Credit Code
      (Vernon's Texas Civil Statutes), Section (a)(1), Article 5069-1.04, as
      amended.

            (c) The provisions of this Section shall be deemed to be
      incorporated into every document or communication relating to the
      Indebtedness which sets forth or prescribes any account, right or claims
      or alleged account, right or claim of the Bank with respect to the
      Borrower (or any other Obligor in respect of the Indebtedness), whether or
      not any provisions of this Section is referred to therein. All such
      documents and communications and all figures set forth therein shall, for
      the sole purpose of computing the extent of the obligations asserted by
      the Bank thereunder, be automatically recomputed by the Borrower or any
      other Obligor, and by any court considering the same, to give effect to
      the adjustments or credits required by this Section.

            (d) If the applicable state or federal law is amended in the future
      to allow a greater rate of interest to be charged under this Agreement
      than is presently allowed by applicable state or federal law, then the
      limitation of interest hereunder shall be increased to the maximum rate of
      interest allowed by applicable state or federal law, as amended, which
      increase shall be effective hereunder on the effective date of such
      amendment, and all interest charges owing to the Bank by reason thereof
      shall be payable upon demand.

            (e) The provisions of Chapter 15 of the Texas Credit Code (Vernon's
      Texas Civil Statutes), Article 5069-15, as amended, are specifically
      declared by the parties hereto not to be applicable to this Agreement or
      any of the other agreements executed in connection herewith or therewith
      or to the transactions contemplated hereby or thereby.

      9.17. SEVERABILITY OF PROVISIONS. Any provision of this Agreement, any
Note or any other Loan Documents that is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions of this Agreement, such Note or such other documents or affecting the
validity or enforceability of such provision in any other jurisdiction.

result thereof will be to cause the Borrower to deal directly with another

Loans. Unless the provisions would otherwise require, any reference to "Loan
Agreement" contained in any Loan Document shall be deemed to refer to this
Agreement, as it may be amended, restated, modified and supplemented from time
to time. The Bank hereby waives the occurrence of any Default or Event of
Default (as those terms are defined in the Original Loan Agreement) which may or
may not have occurred under the provisions of Section 6.7 of the Original Loan
Agreement (the "Fixed Charge Coverage Ratio") prior to the date of this

but which are defined in the Loan Agreement or in the other Loan Documents,
shall have the meanings herein ascribed to them therein. The term "Agreement" as
used in the Loan Agreement and the term "Loan Agreement," as used in the other
Loan Documents or any other instrument, document or writing

                                     6
<PAGE>
furnished to Lender by Borrower shall mean the Loan Agreement as hereby amended.
The term "Revolving Note" as used in the Loan Agreement and the other Loan
Documents or any other instrument, document or writing furnished to Lender by
Borrower shall mean the Revolving Note as substituted for pursuant to this
Amendment. The term "Term Note A" as used in the Loan Agreement and the other
Loan Documents or any other instrument, document or writing furnished to Lender
by Borrower shall mean Term Note A as substituted for pursuant to this
Amendment.

      16. EXPENSES; INDEMNIFICATION. TO THE EXTENT NOT PROHIBITED BY APPLICABLE
LAW, BORROWER WILL PAY ALL COSTS AND EXPENSES AND REIMBURSE LENDER FOR ANY AND
ALL EXPENDITURES OF EVERY CHARACTER INCURRED OR EXPENDED FROM TIME TO TIME,
REGARDLESS OF WHETHER A DEFAULT HAS OCCURRED, IN CONNECTION WITH THE
PREPARATION, NEGOTIATION, DOCUMENTATION, RECORDING, CLOSING, RENEWAL, REVISION,
MODIFICATION, INCREASE, REVIEW OR RESTRUCTURING OF THIS AMENDMENT.

      17. NO USURY INTENDED; SPREADING. Notwithstanding any provision to the
contrary contained in this Amendment, the Notes or any of the other Loan
Documents, it is expressly provided that in no case or event shall the aggregate
of (i) all interest on the unpaid balance of the Notes, accrued or paid from the
date hereof and (ii) the aggregate of any other amounts accrued or paid pursuant
to the Notes or any of the other Loan Documents, which under applicable laws are
or may be deemed to constitute interest upon the indebtedness evidenced by the
Notes ever exceed the Maximum Legal Rate. In this connection, the parties hereto
expressly stipulate and agree that it is their common and overriding intent to
contract in strict compliance with the applicable usury laws. In furtherance
thereof, none of the terms of the Notes or any of the other Loan Documents shall
ever be construed to create a contract to pay, as consideration for the use,
forbearance or detention of money, interest at a rate in excess of the Maximum
Legal Rate. No Borrower nor any other parties now or hereafter becoming liable
for payment of the indebtedness evidenced by the Notes shall ever be liable for
interest in excess of the Maximum Legal Rate. If, for any reason whatever, the
interest paid or received on the Notes during its full term produces a rate
which exceeds the Maximum Legal Rate, the holder of the Notes shall credit
against the principal of the Notes (or, if such indebtedness shall have been
paid in full, shall refund to the payor of such interest) such portion of said
interest as shall be necessary to cause the interest paid on the Notes to
produce a rate equal to the Maximum Legal Rate. All sums paid or agreed to be
paid to the holder of the Notes for the use, forbearance or detention of the
indebtedness evidenced thereby shall, to the extent permitted by applicable law,
be amortized, prorated, allocated and spread in equal parts throughout the full
term of the Notes, so that the interest rate is uniform throughout the full term
of the Notes. The provisions of this paragraph shall control all agreements,
whether now or hereafter existing and whether written or oral, between Borrower
and Lender.

      18. BUSINESS LOANS. Borrower warrants and represents to Lender and all
other holders of the Notes that all loans evidenced by the Notes are and will be
for business, commercial, investment or other similar purpose and not primarily
for personal, family, household or agricultural use, as such terms are used in
Chapter One.

                                     7
<PAGE>
      19. WAIVER OF JURY TRIAL. BORROWER AND LENDER HEREBY IRREVOCABLY WAIVE THE
RIGHT TO TRAIL BY JURY WITH RESPECT TO ANY AND ALL ACTIONS OR PROCEEDINGS AT ANY
TIME IN WHICH THE BORROWER AND LENDER ARE PARTIES ARISING OUT OF THIS AMENDMENT,
THE LOAN AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.

      20. LIEN CONTINUATION; MISCELLANEOUS. Borrower and Lender hereby
acknowledge, confirm and agree that the Security Documents secure and shall
continue to secure the obligations of Borrower and any other party to any of the
Loan Documents (other than Lender) under the Loan Documents, including, without
limitation, this Amendment, the Notes, the Letter of Credit Liabilities and the
Security Documents are hereby deemed modified to the extent necessary to
evidence the foregoing acknowledgments, agreements and confirmations. Nothing
contained in this Amendment or the Notes or any other document, instrument or
other writing executed in connection with this Amendment shall be construed as a
release or impairment of any of the liens, assignments and security interests
created or granted pursuant to the Security Documents and such liens,
assignments and security interests are hereby ratified and confirmed. The Liens
are not waived. To the extent of any conflict between the Loan Agreement or any
of the other Loan Documents (or any earlier modification of any of them) and
this Amendment, this Amendment shall control. Except as hereby expressly
modified, all terms of the Loan Agreement and the other Loan Documents (as any
of them may have been previously modified by any written agreement) remain in
full force and effect. This Amendment (a) shall bind and benefit Borrower and,
except as herein expressly limited, Lender, and their respective receivers,
trustees, successors and assigns (PROVIDED, that Borrower may not assign its
rights hereunder without the prior written consent of Lender); (b) may be
modified or amended only by a writing signed by each party; (c) SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE APPLICABLE LAWS OF THE STATE OF
TEXAS AND THE UNITED STATES OF AMERICA FROM TIME TO TIME IN EFFECT; (d) may be
executed in several counterparts, and by the parties hereto in separate
counterparts, and each counterpart, when executed and delivered, shall
constitute an original agreement enforceable against all who signed it without
production of or accounting for any other counterpart, and all separate
counterparts shall constitute the same agreement and (e) embodies the entire
agreement and understanding between the parties with respect to modifications of
instruments provided for herein and supersedes all prior conflicting or
inconsistent agreements, consents and understandings relating to such subject
matter. Borrower acknowledges and agrees that there are no oral agreements among
the parties with respect to the transactions contemplated by the Loan Documents
which have not been incorporated in this Amendment or in the Loan Documents. If
any provision of this Amendment should be determined by any court of competent
jurisdiction to be illegal, invalid or unenforceable under present or future
laws, the legality, validity and enforceability of the remaining provisions of
this Amendment shall not be affected thereby. Each waiver in this Amendment is
subject to the overriding and controlling rule that it shall be effective only
if and to the extent that (a) it is not prohibited by applicable law and (b)
applicable law neither provides for nor allows any material sanctions to be
imposed against Lender for having bargained for and obtained it. Wherever

                                     8
<PAGE>
the term "including" or a similar term is used in this Amendment, it shall be
read as if it were "including by way of example only and without in any way
limiting the generality of the clause or concept referred to." Any exhibits,
appendices and annexes described in this Amendment as being attached to it are
hereby incorporated into it. The headings in this Amendment shall be accorded no

      2. LOAN AGREEMENT; ADVANCES; SECURITY. This note has been issued pursuant
to the terms of the Loan Agreement, and is Term Note A referred to in the Loan
Agreement. Advances against this note by Payee or other holder hereof shall be
governed by the terms and provisions of the Loan Agreement. Reference is hereby
made to the Loan Agreement for all purposes. Payee is entitled to the benefits

      5. NO USURY INTENDED; SPREADING. Reference is hereby made to Section 2.5
of the Loan Agreement, which is incorporated herein and hereby made a part
hereof. Notwithstanding any provision to the contrary contained in this note or
any of the other Loan Documents, it is expressly provided that in no case or
event shall the aggregate of (i) all interest on the unpaid balance of this
note, accrued or paid from the date hereof and (ii) the aggregate of any other
amounts accrued or paid pursuant to this note or any of the other Loan
Documents, which under applicable laws are or may be deemed to constitute
interest upon the indebtedness evidenced by this note from the date hereof, ever
exceed the Maximum Legal Rate. In this connection, Maker and Payee stipulate and
agree that it is their common and overriding intent to contract in strict
compliance with applicable usury laws. In furtherance thereof, none of the terms
of this note or any of the other Loan Documents shall ever be construed to
create a contract to pay, as consideration for the use, forbearance or detention
of money, interest at a rate in excess of the Maximum Legal Rate. Maker or other
parties now or hereafter becoming liable for payment of the indebtedness
evidenced by this note shall never be liable for interest in excess of the
Maximum Legal Rate. If, for any reason whatever, the interest paid or received
on this note during its full term produces a rate which exceeds the Maximum
Legal Rate, the holder of this note shall credit against the principal of this
note (or, if such indebtedness shall have been paid in full, shall refund to the
payor of such interest) such portion of said interest as shall be necessary to
cause the interest paid on this note to produce a rate equal to the Maximum
Legal Rate. All sums paid or agreed to be paid to the holder of this note for
the use, forbearance or detention of the indebtedness evidenced hereby shall, to
the extent permitted by applicable law, be amortized, prorated, allocated and
spread in equal parts throughout the full term of this note, so that the
interest rate is uniform throughout the full term of this note. The provisions
of this Paragraph shall control all agreements, whether now or hereafter
existing and whether written or oral, between Maker and Payee.

      6. DEFAULT. If any Default or Event of Default or similar event (however
denominated) occurs under any Loan Document, then that shall automatically
constitute default under this note, the obligation (if any) of Payee to make
further advances against this note shall cease and terminate and the owner or
holder hereof may, at its, his or her option, exercise any or all rights, powers
and remedies afforded under any Loan Document and by law, including the right to
declare the unpaid balance of principal and accrued interest on this note at
once mature and payable.

      7. NO WAIVER BY PAYEE. No delay or omission of Payee or any other holder
hereof to exercise any power, right or remedy accruing to Payee or any other
holder hereof shall impair any such power, right or remedy or shall be construed
to be a waiver of the right to exercise any such power, right or remedy. Payee's
right to accelerate this note for any late payment or Maker's failure to timely
fulfill its other obligations hereunder or under the other Loan Documents shall
not be waived or deemed waived by Payee by Payee's having accepted a late
payment or late payments in the past or Payee otherwise not accelerating this
note or exercising other remedies for Maker's failure to timely perform its
obligations hereunder or under the other Loan Documents. Payee shall not be

                             Page 3 of 6 Pages
<PAGE>
obligated or be deemed obligated to notify Maker that it is requiring Maker to
strictly comply with the terms and provisions of this note and the other Loan
Documents before accelerating this note and exercising its other remedies
hereunder or under the other Loan Documents because of Maker's failure to timely
perform its obligations under this note and the other Loan Documents.

      8. WAIVERS BY MAKER AND OTHERS. Except to the extent, if any, that notice
of default is expressly required herein or in any of the other Loan Documents,
Maker and any and all co-makers, endorsers, guarantors and sureties severally
waive notice (including, but not limited to, notice of intent to accelerate and
notice of acceleration, notice of protest and notice of dishonor), demand,
presentment for payment, protest, diligence in collecting and the filing of suit
for the purpose of fixing liability and consent that the time of payment hereof
may be extended and re-extended from time to time without notice to any of them.
Each such person agrees that his, her or its liability on or with respect to
this note shall not be affected by any release of or change in any guaranty or
security at any time existing or by any failure to perfect or to maintain
perfection of any lien against or security interest in any such security or the
partial or complete unenforceability of any guaranty or other surety obligation,
in each case in whole or in part, with or without notice and before or after
maturity.

      9. PARAGRAPH HEADINGS. Paragraph headings appearing in this note are for
convenient reference only and shall not be used to interpret or limit the
meaning of any provision of this note.

      10. VENUE; CHOICE OF LAW. This note is performable in Harris County,
Texas, which shall be a proper place of venue for suit on or in respect of this
note. Maker hereby irrevocably agrees that any legal proceeding in respect of
this note shall be brought in the district courts of Harris County, Texas, or in
the United States District Court for the Southern District of Texas, Houston
Division (collectively, the "SPECIFIED COURTS"). Maker hereby irrevocably
submits to the nonexclusive jurisdiction of the state and federal courts of the
State of Texas. Maker hereby irrevocably waives, to the fullest extent permitted
by law, any objection which it may now or hereafter have to the laying of venue
of any suit, action or proceeding arising out of or relating to this note or any
of the Loan Documents brought in any Specified Court, and hereby further
irrevocably waives any claims that any such suit, action or proceeding brought
in any such court has been brought in an inconvenient forum. Maker further
irrevocably consents to the service of process out of any of the Specified
Courts in any such suit, action or proceeding by the mailing of copies thereof
by certified mail, return receipt requested, postage prepaid, to Maker. Nothing
herein shall affect the right of Payee to commence legal proceedings or
otherwise proceed against Maker in any jurisdiction or to serve process in any
manner permitted by applicable law. Maker agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE

                             Page 4 of 6 Pages
<PAGE>
APPLICABLE LAWS OF THE STATE OF TEXAS AND THE UNITED STATES OF AMERICA FROM TIME

      11. OFFSET RIGHTS. Payee is hereby authorized at any time and from time to
time, without notice to any person or entity (and Maker hereby WAIVES any such

monies, securities and other properties of Maker now or in the future in the
possession, custody or control of Payee, or on deposit with or otherwise owed to
Maker by Payee--including without limitation all such monies, securities and
other properties held in general, special, time, demand, provisional or final
accounts or for safekeeping or as collateral or otherwise (but excluding those
accounts clearly designated as escrow or trust accounts held by Maker for others
unaffiliated with Maker)--against any and all of Maker's obligations to Payee
now or hereafter existing under this note, irrespective of whether Payee shall
have made any demand under this note. Payee agrees to use reasonable efforts to
promptly notify Maker after any such set-off and application made by Payee,
PROVIDED that failure to give--or delay in giving--any such notice shall not
affect the validity of such set-off and application or impose any liability on
Payee. Payee's rights under this Paragraph are in addition to other rights and
remedies (including, without limitation, other rights of set-off) which Payee
may have.

and enforceability of the remaining provisions of this note shall not be
affected thereby, and this note shall be liberally construed so as to carry out
the intent of the parties to it. Each waiver in this note is subject to the
overriding and controlling rule that it shall be effective only if and to the
extent that (a) it is not prohibited by applicable law and (b) applicable law
neither provides for nor allows any material sanctions to be imposed against
Payee for having bargained for and obtained it.

      15. SALE AND ASSIGNMENT. Payee reserves the right, exercisable in its sole

      THIS FIRST MODIFICATION TO CONVERTIBLE SUBORDINATED PROMISSORY NOTE (this
"Modification") dated as of September 30, 1997, between Henley Healthcare, Inc.,
a Texas corporation (the "Company"), and Maxxim Medical, Inc., a Delaware
corporation (the "Holder"). Hereinafter, capitalized words and phrases used
herein which are defined in the Note (as such term is hereinafter defined) are
used herein as therein defined, unless otherwise indicated.

                                   WITNESSETH

      WHEREAS, the Company issued to the Holder a $7,000,000 Convertible
Subordinated Promissory Note dated as of April 30, 1996 (the "Note");

      WHEREAS, the Company intends to enter into that certain Asset Purchase
Agreement on September 30, 1997, between the Company and CYBEX International,
Inc., a New York corporation ("CYBEX"), whereby the Company will acquire certain
of the assets of CYBEX;

      WHEREAS, in connection with the CYBEX acquisition, the Company has
requested that the Holder execute an amendment (the "Subordination Amendment")
to that certain Subordination Agreement, dated as of April 30, 1996, by and
among the Holder, the Company and Comerica Bank - Texas (the "Subordination
Agreement") increasing the amount of allowable indebtedness under the Senior
Loan Documents (as defined in the Subordination Agreement) from $10,000,000 to
12,000,000;

      WHEREAS, the Holder has agreed to execute the Subordination Amendment in
exchange for the reduction of its Conversion Price (as defined in the Note) from
$3.00 to $2.00; and

      WHEREAS, the parties hereto desire to modify the applicable provisions of
the Note.

      NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants and agreements hereinafter set forth, the parties hereto hereby agree
as follows:

      1.    MODIFICATION OF THE NOTE.

            1.1 Section 4.1 of the Note is hereby deleted and the following
      section is substituted therefor:

            "4.1 CONVERSION PRIVILEGE AND CONVERSION PRICE. Subject to and upon
      compliance with the provisions of this Article IV, at the option of the
      Holder, all or any portion of the amounts owed and outstanding under this
      Note may be converted at any time and from time to time into fully paid
      and nonassessable shares of Common Stock (the "Shares"), calculated as to
      each conversion to the nearest 1/100 of a share at the Conversion Price,
      determined as hereinafter provided, in effect at the

                                      1
<PAGE>
      time of conversion. Unless and until the occurrence of an Event of
      Default, the Conversion Price shall be $2.00 per share of Common Stock,
      subject to adjustment in accordance with Article 5 hereof. Upon the
      occurrence of an Event of Default, the Conversion Price shall be
      automatically adjusted to an amount equal to the lesser of (i) the
      Conversion Price in effect as of the date of the Event of Default and (ii)
      80% of the average Market Price for the 30 trading days immediately
      preceding the date of the Event of Default, which amount shall be subject
      to further adjustment in accordance with Article 5 hereof. All amounts so
      converted shall be applied first to pay any accrued and unpaid interest
      and second to reduce the principal amount of this Note as of the date of
      such conversion as if payment or prepayment in such amount has occurred,
      with any reduction in principal to be applied to satisfy the Company's
      redemption obligations under Section 2.3.2 hereof in accordance with
      Section 2.3.4 hereof. This right of conversion must be exercised by
      delivery of a written notice to the Company setting forth the amount to be
      converted to be effective upon the Company's receipt of such notice (the
      "Conversion Notice"). Notwithstanding the foregoing, in the event the
      Company provides notice to the Holder of its intention to redeem all or
      any portion of the outstanding principal balance of this Note pursuant to
      Section 2.3.1 hereof, the Company must receive the Conversion Notice on or
      before the last Business Day prior to the effective date of such
      redemption to the extent that the Holder desires to convert all or any
      portion of the amount to be redeemed by the Company."

            1.2 Section 6.7(b) of the Note is hereby deleted and the following
      section is substituted therefor:

                  "(b) Funded Debt of the Company under the Senior Indebtedness
      not exceeding $12,000,000 in aggregate principal amount at any one time
      outstanding;"

      2. NO FURTHER EFFECT. Except as expressly modified hereby, the Note shall
remain in full force and effect.

      3. GOVERNING LAW. This Modification shall be governed by and construed in
accordance with the laws of the State of Texas.

      4. COUNTERPARTS; EFFECTIVENESS. This Modification may be signed in any
number of counterparts, each of which shall be an original, and with the effect
as if the signatures thereto and hereto were upon the same instrument. This
Modification shall be effective as of the date hereof when each of the parties
hereto shall have executed counterparts hereof.

      5. ORAL AGREEMENTS. This Modification represents the final expression
between the parties with respect to the subject matter hereof, and may not be
contradicted by evidence of prior or contemporaneous oral agreement of the
parties.

      IN WITNESS WHEREOF, the parties hereto have caused this Modification to be
executed as of the date first written above.
